Biography of and Principles Taught By Niccolo Machiavelli...

Machiavelli Essay: Question 1 Born in the 15th century, Niccolà ² Machiavelli was an Italian historian, politician, philosopher, diplomat and humanist. Following his career as an official in the Florentine Republic, Machiavelli was a founder of modern political science and political ethics. In the political treatise The Prince, written in 1532, Machiavelli outlines several key traits of a successful princedom such as; how to incorporate newly acquired provinces, the most successful way to conquer territories, the establishment of successful defense and military forces, as well as qualities which would make for the most desirable prince. Machiavelli also brings to attention the pitfalls of previous Italian princes as to prevent the same†¦show more content†¦The increase on virtue shifted the public’s attitude away from chance and towards ambition and risk taking. Machiavelli outlines several steps that princes can take in order to create a successful principality. When analyzing the success of principalities, a balance of state interests with those of the individual’s must exist. The original moral basis for princely rule focused on domination and forced subjection, whereas the new basis suggesting the gain of citizen support as well as appearance of generosity and the ability to balance cruelty and mercy. The observation that a change is necessary can be seen through the lines, â€Å"He who abandons what is done for what ought to be done, will rather learn to bring his own ruin than his preservation† (Machiavelli 56). Machiavelli believed that the rulers of Italy had lost their states as a result of ignoring the political and military principles he believed attributes to a successful ruler. Throughout The Prince Machiavelli outlines and offers advice to future rulers with the hopes that they will improve themselves and thus improve the society as a whole as shown in the quote, â€Å"Whoever considers the past and the present will readily observe that all cities and all people are end ever have been animated by the same desires and the same passions;† (Machiavelli 216).

I like to think that I am caring, hardworking and honest. I’m thoughtful because I care for other people; I like to know what’s going on with people and if something is on their mind. I’m a hard worker because I strive to do my best at anything I do, I don’t like to see myself fail at any goal I’m trying to accomplish. I’m truthful because I’ve been lied to as a child and in the past. The feeling of being lied to hurts, it makes someone feel as though their feelings or emotions don’t matter and that their not strong enough to handle the truth. Me personally, I would never want to lie to someone and put them through anything they shouldn’t have to go through. One bad thing about me is that I’m judgmental, I judge people before I even get the chance to meet them or even know what their like. If I see someone I stereotype them and until I really get to know the person well, I always just have those thoughts. Another thing about me is that I’m naive. I believe anything anyone tells me; someone can tell me there’s a fire in my house while I’m in it and ill say â€Å"where? † The worst thing about me is my attitude. I have a bad attitude and if I don’t like someone it definitely shows, but I have frequent mood swings. If I’m having a bad day or someone frustrated me, half my day will be ruined and ill take it out on everyone else but not intentionally. I have a well rounded personality, I feel as though I’m a easy person to get along with; I’m helpful, friendly, and trustworthy. I like to be beneficial to anyone who needs it, everyone needs a helping hand every once in a while and need someone to help them get on their feet; I like to be that person. I’m extremely outgoing I like to have a good time and enjoy myself know matter where I’m at. I don’t like anyone feeling left out so I always try to make the person I’m with have as much as a good time I’m having. Having someone who is dependable is important. Everyone needs that one friend who they can run to and tell all there secrets to and not second guess them even telling a soul, I feel as though I’m very reliable. A few negative personality traits I have are being shy, stubborn and not talkative. I’m very timid around people I don’t know or around people I feel uncomfortable with, but once I get to know you very welcoming and outgoing. If I don’t know you, I wont talk to you or try to conversate with you, I’m not talkative to people I’m not familiar with. The worst personality trait I have is being stubborn. If I could change me being stubborn I definitely would. Being obstinate can cause a lot of conflict especially with other obstinate people; if things don’t go my way I become highly frustrated very fast. I interviewed three people and how they view me as an individual, I wasn’t too surprise with the responses I received because I can see why they would think that way about me. Some positive things that were said about me are that I’m very responsible, dependable and hardworking. I, myself had also thought I was hardworking; I like to achieve all my goals and get everything done. I’m reliable because everyone knows if they ask me to do something and I’m able to do it, it will get done. That’s sort of where my perfectionist kicks in, where everything has to be done right and in order. A few negative things that my family thought was being hardheaded, impatient and having a bad attitude. I admit that I’m hardheaded because I don’t listen to what people tell me even if they know for a fact it’s a bad decision. I like to make my own mistakes and learn from them because if you don’t learn from your mistakes you’re going to keep making them. I also agree that I’m intolerant because I have no patience to wait for anything. I get easily frustrated when something takes longer than it has to. I take my school work and jobs very seriously, so when it comes to school I work I don’t play around and try my hardest to do everything the way it’s suppose to be and to do everything on time. I’m extremely hard working; I strive to do my best in any and everything I do so I can make something out of myself. I’m a very driven person when it comes to something important because if you loose sight of the big picture, your goals or ambitions you will be lost in the long run and it will take you longer to get to where you want to be. I’m so determined to make something of myself because my whole life I’ve seen my family struggling just to make ends meet and I don’t want to see myself in their shoes, I want to succeed and be someone in the future. I do have a few negative attribute when it comes to performance at school or work, just like everyone else. I’m easily sidetracked because when I’m focused on something I want done and another thing pops up or needs to be done such as cleaning, phone calls or picking up my sister I’ll do it with out finishing the first thing I was doing. I’m most distracted when I’m in school because if I get a text message or phone call while taking notes or listening to a lecture I loose concentration. Being a procrastinator is the worst trait I think I could have picked up on because I throw important things to the backburner, thinking I will do it when I’m ready or when I’m finished with something and I end up forgetting about it all together. I’m often sluggish because I go to school Monday through Thursdays and work everyday, so sometimes I won’t finish or accomplish many things such as homework, projects or studying because I just want sit around, rest or sleep all day. Throughout the day, I’m a pretty laid back relaxed person. I get things done in that process though. I keep myself motivated because if I’m not motivated I won’t succeed but I’m a very organized person and that shows that I care about my priorities. My biggest problem that I’ve dealt with my whole life is waking up late. I tend to sleep in or over sleep most of the time, that’s not a good attribute because I waste my entire day by sleeping and sometimes I’m late to class and miss parts of a lectures. Throughout the day I find myself cleaning up after my self and other all the time. I’m too much of a clean freak, I usually annoy people who are with or around me and because I’m always straightening up the house. A non-clean person irritates me to death, it makes me mad when people don’t clean up after their selves. When it comes to mental functioning I like to think of myself as a multitasked person, very curious and spontaneous, independent, antagonistic, horrible at math and having a bad memory. Being able to do a lot of things at once is a positive attribute to me as long as your doing all the things correct; I can get many things done at one time while doing an impressive job. I like the fact that I’m curious and spontaneous, I like to discover and try new things because we only live once. My friends love hanging out with me and anyways ask me about things to do. I’m a very independent person who doesn’t like to seek help from others, I like to do things on my own and provide for myself, it makes me feel good. I feel as though I need to work for what I want because nothing is ever given to you. Math is my worst subject and I’ve always struggled with it throughout my life, but I’ve come to realize that I am not the only person with that problem. Now that I am in college and need to take 3 more semesters of math I seek help from the math tutors and by doing that I have learned a great amount, math is beginning to become understanding instead of stressful. Having a bad memory is a bad attribute that I have I can never remember important things that I’m suppose to remember. If I’m having a conversation with someone and I get sidetracked I’ll forget my entire train of thought. My friends and family get frustrated with me when I forget things.

The Middle Ages free essay sample

The Middle Ages come into being around A. D. 500, which was after the western half of the Roman Empire collapsed. They lasted to about A. D. 1400 and are referenced to as a period of time that experienced violence by Barbaric invasion, feudalism, disease, and strong feelings for faith. The Dark Ages, the Age of Feudalism and the Age of Faith are all appropriate titles, however the label that best fits is the Age of Faith because of the political, economic and social influence the church held. The middle ages are often identified as the Dark Age because of the Black Death, invasions by the Barbarians, and because of lack of enlightenment for the common people. A plague most likely originating from Asia spread throughout Europe. Towns and even large cities had no garbage collection or a sewage system and this caused the crowded towns to become filthy and attract rats (OI). The Black Death caused social unrest and people pondered what was going on; many believed that God was punishing them while others claimed the Jews were to blame. With the Black Death overtaking the lives of everyone there were not many achievements or educational advancements during this time as all focus was on trying to get through the plague. After the fall of the Roman Empire there was no stable centralized government in Rome. Different Barbarian civilizations began invasions in Europe. According to historian Frantz Funk-Brentano they raided and destroyed villages and left the people in terror. Brentano also said that to avoid the violence people tried to abandon their fields. Churches and entire towns were burned down; the town of Dordrecht was burned down by Barbarian tribes such as the Vikings triggered chaos (Doc. 3). This caused people to abandon their lifestyles and that meant a decline in trade, which brought down the economy. During this period of time most people were illiterate and they did not go to school. Instead they learned different skills and jobs from their parents, apprenticeships, and the guild system. One of the few ways to become educated was to join the clergy where Priests and Monks would learn Latin. OI) It took dedication to become a part of the clergy, A Brother taking his monastic vows had to renounce everyone he knew and everything he had including his free will (Doc. 8). Not everyone was able to become a part of the clergy so they were reliant on these people to share the word of God from them. The Dark Ages had negative impact because the increased reliance on the church gave them even more power, and this challenged Kings and created potential political tension. During the middle ages the lack of protection and a stable government after the Fall of Rome created the need for a new political system. Feudalism was the political system that emerged and shaped the lives of people socially and politically. Manors were small communities that were made up of a castle, church, village, and land for farming. The structured society provided a place and responsibility for everyone. The feudal obligations showed that in exchange for one thing they would be provided with something else. Serfs and peasants would work and produce goods for the rest of the manor and in return had their land and promised protection. The vassals would need to obtain land from the Lord and in return would provide the Lord with military service, loyalty, and ransom if asked for (Doc. 4). To make clear the vassal’s specific allegiance to their lord whom they owed in for exchange for their fief they would take the Homage Oath (Doc. 2). This interdependent system required everyone to do their part and it created social classes that they were born into. Their daily lives were centered on the manor and that was how it stayed until towns began to grow into cities after the crusades (OI). Feudalism had positive bearings because it was the solution for decentralized government and lack of protection but also held people back due to lack of social mobility. The Age of Faith is most accurate for describing the Middle Ages because of the political, social and economic influence the church held. Feudalism was still not providing one united central government but instead many small ones and so the church gained a governmental authority over Western Europe. People were all working to try to get into Heaven, and because of that there was a lot of control over telling people what to do. The church could excommunicate people and even Kings if they felt that they were refusing to comply (OI). This gave the church power over the Kings because they controlled who would not be allowed to return to the church; if someone were excommunicated they would not be able to reach Heaven. At the time the bible was written in Latin, which only could be read to the common people by a clergy member who could explain what was written. With the reliance on the church the pope’s words and explanations were taken as God’s. The Truce of God stated different peace agreements, which they enforced by exerting their power and influence (Doc. 5). The Crusades were a major part of this because the church declared to try to capture the Holy land. Pope Urban II called for people to join the Holy Crusade and persuaded them by saying that those who agreed to fight during the crusades were promised entrance into heaven and forgiveness of sins (Doc. 9). This was the beginning of economic expansion because the crusaders became accustomed with the culture and goods. Trade opened up and port/merchant cities developed. Church also dominated sectors of society such as architecture, which began to grow because during the age of Faith having a Cathedral gave a town an identity. Gothic Cathedrals had dramatic features and stood out in height and important in comparison to other structures in the towns (Doc. 10). The church also issued a tithe tax, which was 1/10 of a person’s income to go towards building churches, monasteries, convents, and universities (OI). The Church’s control and influence over Western Europe was sometimes used for corrupt purposes and persuasion but that was not only the case because it brought prosperity to the economy. The Middle Ages can also be stated as the Age of Faith because the main center of attention and one’s purpose in life was to serve God and live righteously. More than one title can be assigned to the Middle Ages due to the overlapping of events but the Age of Faith applied almost continuously to the lives of people throughout the Middle Ages while other labels such as the Dark Age and the Age of Feudalism represented certain periods of it.

Role of Women in Society

A woman is opposite sex of a man. Women have been of great importance for many generations. Women play the role of wives and mothers in any society. Some religious principals such as the Christians do believe that a woman was created out of man and was given the mandate of giving companionship to the man.Advertising We will write a custom essay sample on Role of Women in Society specifically for you for only $16.05 $11/page Learn More This principal has some truth in the fact that in our society we see women giving companionship to men by being their wives. Apart from this, the woman is the one who gives new life. She posses a womb that a man does not posses. The womb was specifically created for the development of the baby. After this, she gives birth and becomes the mother to the baby. Women are more responsible when it comes to matters related to the family; they have to ensure that every thing is running smoothly as expected. Not only are women conce ntrated on matters of the family but in today’s generation, they are also a key player of the economy in different ways. In the past, the woman was seen as an inferior person who was only expected to remain at home, do the household chores, and take care of the babies. The man was the one to go to work and provide the daily bread for the family, which made men mistreat their wives because women had no power to raise their views or opinions but rather they had to submit to their husbands’ orders. Nevertheless, in today’s world, women go to work and earn money that they join with that of the husband to keep up the family. In addition, the small girls were also gender biased in the fact that they were expectected to remain at home and help their mothers in the house chores while the boys went to school to get education. This left the female child with no option but to remain uncivilized in her entire life. However, in today’s generation, the female child goe s to school and acquires the same education as the male child. It is considered unethical if the parents of the female child fail to take the female child to school and in some countries it is punishable by law. This has led the female child to develop into a very civilized woman that is well updated with the current matters that surround her. Today it is not a shock to see a woman driving good cars, building modern houses because they have become capable to do so. They benefit the economy of a particular country as stated earlier in the fact that they become tax payers which adds a certain percentage of revenue to that particular country.Advertising Looking for essay on gender studies?

This stance is really h elping the respective state and that is why the government of a particular country is protecting the rights of the women in their countries. The woman of today has been given the freedom to exercise their views and opinions concerning political matters. They can even try themselves for any parliamentary seat as long as they meet the legal requirements as stipulated by the constitution of that particular country. This has really contributed to the development of countries because men in power are aware of the present competition and criticism if they fail to deliver their mandate effectively. Women are also becoming key players in technological advancement all over the world, they possess innovative minds, they are developing machines and other related gadgets to reduce the manual work of human labor and increase the use of machines. This creates employment to the people that will be handling the machines. Women are also human beings that are identified by beauty. it is said that a w oman can take 50 percent of her time to look appealing. If a woman does not look beautiful, she faces discrimination in the society. This makes the women all over the world place their beauty as a priority and not as an option. Every man in the world desires to marry a woman that is envied by the society, therefore, the woman who does not maintain her beauty is at the risk of being left unmarried. It is important that all women should ensure that they maintain their inward and outward beauty if they have to be considered as beautiful and responsible in the society. Being a woman also has its disadvantages in various ways such as in the birth stage. Some women hate when they are pregnant so they try to avoid this stage and prefer an operation, which is costly and dangerous. Women also are disadvantaged when they are undergoing menstrual cycle because it is accompanied by some specific features. Another disadvantage that the majority of women hate is the issue of being submissive to t heir husbands. Although they may prefer to remain independent, they have no option but to get married because they need a man to bear and have a child. Even if they decide to get a child out of marriage that will affect their child or children lacking a father being part and parcel of normal upbringing.Advertising We will write a custom essay sample on Role of Women in Society specifically for you for only $16.05 $11/page Learn More Being a woman is full of responsibilities because they did not elope from household chores even though they live in a civilized society. In fact, their responsibilities have increased because they have to perform their household chores as they still have to perform their household responsibilities. They also have to leave some spare time for spending with their families. That is why a research that has been conducted demonstrates women as people who can multi task unlike men who can only do one thing at a time. From the abov e essay, it is evident that women are creatures of great significant in our society today. They should not be prejudiced by anyone in the society. Women are continuing to establish roots and fight for their rights by developing their organizations that do fight for their rights. It is my hope that each woman in the world will embrace the traits discussed in the above essay to ensure that they truly know the value of being a woman.

She Walks In Beauty Essays - Lord Byron, Missolonghi, Philhellenes

She Walks In Beauty Essays - Lord Byron, Missolonghi, Philhellenes She Walks in Beauty George Gordon Noel Byron's poem titled, "She Walks in Beauty," plainly put, is a love poem about a beautiful woman and all of her features. The poem follows a basic iambic tetrameter with an unaccented syllable followed by an accented syllable that allows for a rhythm to be set by the reader and can be clearly seen when one looks at a line: She walks / in beau / ty like / the night. T.S. Eliot, an American poet criticizes Byron's work by stating the poem, "needs to be read very rapidly because if one slows down the poetry vanishes and the rhyme is forced" (Eliot 224). With this rhythm the reader can, however, look deeper into the contents of Byron's poem and discover a battle of two forces. The two forces involved in Byron's poem are the darkness and light- at work in the woman's beauty, and also the two areas of her beauty-the internal and the external. The poem appears to be about a lover, but in fact was written about "Byron's cousin, Anne Wilmot, whom he met at a party in a mourning dress of spangled black" (Leung 312). This fact, the black dress that was brightened with spangles, helps the reader to understand the origin of the poem. Byron portrays this, the mixing of the darkness and the light, not by describing the dress or the woman's actions, but by describing her physical beauty as well as her interior strengths. In the beginning of the poem, the reade r is given the image of darkness: "She walks in beauty, like the night," but then the line continues explaining that the night is cloudless and the stars are bright. So immediately the poem brings together its two opposing forces that are at work, darkness and light. In lines three and four Byron emphasizes that the unique feature of the woman is her ability to contain opposites within her; "the nest of dark and bright/meet" in her. The joining together of the darkness and the light can be seen in her "aspect," or appearance, but also in her "eyes." In this case, "the woman's eyes aren't to be associated with a physical feature, but more as an internal aspect of her: the eyes reveal her heart"(Martin 24). L.C. Martin, from the University of Nottingham, also writes that Byron, "emphasizes the unique feature of this woman to contain opposites within her,"(24) therefore agreeing with the concept that not only is there a struggle between the darkness and the light, but also within the woman. Beginning with line five, the word "meet" is emphasized again as she creates a "tender light," not the gaudiness of daytime, but a gentler light that even "heaven" does not bestow an the day. The night can be thought of in terms of irrationality and the day in terms or reason and neither day nor night is pleasing, only the meeting of the two extremes in this woman. In the second stanza, once again, the opposites are combined. "Shade" or darkness is combined with "day" or light, and "raven tress" or dark hair is linked with a lightened face. If the woman contained with in her and in her appearance either a little bit more of darkness or a little bit more of light, she would be "half impaired." A key word in this section is "grace." Although Byron continuously talks about appearances, in actuality he is referring to the "nameless grace" that is in her hair and face. Once again, it is something internal as well as external that is so attractive about this woman. Although this poem begins with the image of a woman walking, there are no images given by Byron of her legs or arms or feet; this is a head poem, confined to hair, eyes, face, cheeks, and brows. The conclusion to the second stanza contains insight into "the dwelling place" of the woman's thoughts, creating an insight into her mind by using alliteration. The repetition of the "s" sounds is soothing in the phrase "serenely sweet express," because "Byron is referring to her thoughts, and her thoughts are serene and pure"(25). In the third and final stanza, Byron concludes the poem

Burger King Business Communication Case Study

Burger King Business Communication Case Study Burger King is a fast food Corporation. It is the second largest fast-food chain in the United States, trailing only McDonalds. The company franchises more than 10,400 restaurants and owns about 1,000 for a chain wide total exceeding 11,455, with locations in all 50 states and 56 countries. The company serves 15.7 million customers each day and over 2.4 billion Burger King Hamburgers are sold each year across the globe. Miami entrepreneurs James McLamore and David Edgerton founded Burger King Corporation in 1954. REASONING The reason as to why I have chosen to write a report on Burger King is to illustrate its communication strategies and its communication effectiveness. Business Demographics Demographics are attributes used for marketing purposes. Burger King uses the means of networking, media and the internet to communicate between different locations. The organisation uses its demographical strategies to meets it consumer interests and also for profitability to the company. Burg er King’s demographic strategy is well planned and well laid out, making it easy to market the organisation to its customers who are from different age groups and from different cultural backgrounds. Organisational Goals Burger King’s main aims and objectives are to serve its customers with the bests meals and services a fast food company could possibly provide. To achieve this, the organisation has a zero compromise policy for the communication of its aims and objectives. The aims and objectives are highly important to the organisation, for it is the only way the organisation maintains its integrity amongst it competitors and its customers. Burger King’s aims and objectives are well set and structured, making it relatively easy to communicate them within the organisation and also to its customers. The organisation’s main source to communicate its aims and objectives are through the media, banners, coupons, handouts and also through the internet. ORGANISA TIONAL CULTURE AND ETHICS Burger King is an organisation that serves customers from various backgrounds and cultures. This makes it extremely important to manage communication in the most delicate manner as possible. The organisation has to keep in mind that not all customers consume all the menus the company offers. For example: customers who are from an Indian background won’t eat beef, customers who are from a Muslim background won’t eat pork. Its vital information like these that the organisation has to keep track of in order to meet the needs of people who are from different backgrounds and cultures. Management of Knowledge Resource Management of knowledge resources is critical for any organisation. It helps in ensuring that vital knowledge is passed on within the organisation so that the organisation can maintain its ever long trend of providing the quality of work or service as it has been providing in the past. Burger King is one such Organisation that takes pr ide in its quality of service that it has been known of providing. Achieving this however took a lot of work and experience for the organisation. To ensure that knowledge and experience is passed on within the organisation, the Burger King Management team relies heavily on their old staffs who possess the skills and experience needed for the organisation to maintain its quality of work. The old staff members train and groom the new recruits so that they can cope with the organisations requirement standards and deliver quality services to its customers. The Management team of Burger King also holds staff meetings and orientations to ensure that vital knowledge and experience is equally shared amongst each and every member of the team. The also shuffle the teams together so that there is an equal balance of knowledge and experience within the teams.

Managerial Decision Making essay 8 Example | Topics and Well Written Essays - 1250 words

Managerial Decision Making 8 - Essay Example Most researchers explain analogical thinking as the process of remembering a situation of the past and abstracting information from the same in order to develop better understanding of the present situation (Foreman & Selly, 2001). The purchasing decisions of individuals are influenced by analogical reasoning. It is considered as a technique which shoppers use to increase the satisfaction regarding the purchased commodity or service (Foreman & Selly, 2001). Last week when I was purchasing a mobile handset, I adhered to the information that was provided to me by the store keeper. Instead, if I had used my own analogical reasoning, perhaps I could have made a better purchase. Through analogical reasoning I could have analyzed my previous experiences with different brands. Analogical reasoning could have also helped me to consider and match my needs with the offerings of the product and chose more wisely. Biased behavior is a common issue faced in the daily lives of most individuals. Biasness refers to supporting a particular theory, an individual or to think in a particular manner without being rational. Biasness from others may arise out of different reasons such as lack of knowledge, attachment with particular individuals or the lack of familiarity with certain situations. Biasness may often cause individuals to take wrong decisions (Frame, 2012). Biased thinking may also arise out of individual heuristics. Heuristics is the process of taking decisions quickly without analyzing the same in depth or logically. Such an effect leads to the generation of cognitive biasness. Biased judgment can also arise out of wishful thinking. Wishful thinking and beliefs of individuals may act as suitable motivations for biased decision making. Understanding other people’s biasness is an important aspect while working in teams or while taking decisions collectively. This helps in understandi ng the motive behind their biased thinking. Once the motive is

Organizational Change Final Assignment Example | Topics and Well Written Essays - 2000 words

Organizational Change Final - Assignment Example Apart from the increase in salaries, workers are motivated by various factors such as increased commission, training, freedom to join trade unions, training, gifts, holidays, promotion and increased responsibilities among other factors. On their part, the management team should ensure that employees are involved in the decision making process and that a proper management style is adopted.

Special Needs and the ESL Culture Essay Example for Free

Special Needs and the ESL Culture Essay Special education students are unique because teachers have to do more to teach them than regular students. They already have issues that impair their learning, so it is important that teachers work to individualize instruction as much as possible. This will help ensure the most success. Students who are from another culture, those who do not speak English as their first language, pose additional obstacles for the teacher. First, the teacher has to figure out what part of the student’s delay is caused by limited English proficiency, and what part is caused by the actual disability. This can be time-consuming and difficult, especially if language development is part of their disability. This will affect the way the teacher presents the material. Visual instruction would be most beneficial since there is no language barrier. Second, the teacher has to learn how much English is spoken at home. If the parents speak fluently, then they can take part in helping the student. If the parents are learning themselves, the teacher will have to adapt homework so that they will be able to assist their child. Collaboration is the key for students, parents, and teachers to feel they are doing the most and getting the best results for special needs, ESL students (Collaboration, para 3). If another language is spoken at home, it will take the student even longer to catch up. The teacher could send home material to help parents talk to their child. Students who come from other cultures also may not be prepared for the schedule of a typical school day here in the U. S. A full day of school might be too taxing at the beginning, so the teacher would have to have many breaks built in to the daily activities. It is important that teachers pay attention to the student’s needs since they may not be able to communicate them. Students will also not know what to expect when they are first learning the routine of school here. Picture schedules could be vital in ensuring the student’s feel the safety of a daily routine. The native cultural traditions will also affect how teachers teach in this environment. Some students may be absent for religious holidays when school is in session. Some students may talk about upcoming holidays that we do not have. Teachers should be thoughtful and try to include as many of the customs and traditions as they can. A Cinco de Mayo party may be just the activity to make the student feel welcome and wanted. A final way that ESL students affect the class is their interactions with the other students. The ESL student may try to talk with another student, but because of the language barrier, the student may not be able to understand. The teacher needs to be available to let the student know they did a good job in initiating conversation, and then try to translate so the other student remains engaged. There are so many different factors that make up a special needs class. The delays in development can be ever further hindered if the student is not fluent in English. While there are more obstacles if students do not speak English as their native language, there are also opportunities. The teacher can help ensure the students feel at home here, and that the other students learn to appreciate their culture as well.

Analysis of the Running Man :: essays research papers fc

Analysis of the Running Man Sometimes there are hurdles in life that require great courage to overcome. We must utilize our inner strengths to motivate these courageous actions. Loren Eiseley sets an example of this in The Running Man- a chapter from his autobiography, All the Strange Hours. In this essay he reveals memories that show his lonely childhood which gives him the courage to overcome his problems.   Ã‚  Ã‚  Ã‚  Ã‚  Loneliness is what ultimately sparks his courageous action later on in his life. â€Å"I remember the pacing, the endless pacing of my parents after midnight, while I lay shivering in the cold bed and tried to understand the words that passed between my mother and my father.†(Eisley,337) This quote taken from the running man is just one example of his deep loneliness that he was faced with as a child. Even when he was around his family he still felt lonely. Whenever he came upon a ruined farmhouse and found old papers scattered across the floor that shared his last name, he realized that a German possibly like him had lived there. He was amazed that his family hadn’t known this family. If only the family could have still lived there he would possibly have companions that were a lot like him. After years of torment by his loneliness he grasps his courage and runs. Eiseley is always running, through his childhood and most of his adult life.   Ã‚  Ã‚  Ã‚  Ã‚  He felt there was more out there for him. The life he was living was inadequate. This determination is a product of his childhood aspirations for a better life. This is proven by his childhood tradition of burying things and digging them up again instead of participating in childish games. Eiseley does not know why he would dig in the dirt or play with the gravel. â€Å"There was a lot of building being done then on our street. I used to spend hours turning over the gravel. Why, I wouldn’t know.†(338) As a child he embraces the rush of discovery and the thrill of adventure in his seemingly insignificant dirt pile. He was fueled by a unknown force in his childhood to discover more in life. This gave him the courage to leave home and discover things like science and anthropology.   Ã‚  Ã‚  Ã‚  Ã‚  It takes great courage for Eisley to return to his mother’s grave. In an affect this completes the circle of his life.

Slim Wave in Singapore

A number of diet pill manufacturers from China, such as Kunming Dali Industry and Guangzhou Shining Trading, are riding on Singapore’s â€Å"slim wave† to make money. In Asia, the idea of a slim figure has turned from a Hollywood-induced dream into an obsession. The glossy magazines geared toward women have covers adorned with slim, petite models. Local newspapers constantly feature advertisements portraying slim actresses and models who have transformed themselves from bloated balloons into sunbathing beauties.Slimming is increasingly seen as one of the panaceas for Singapore’s societal ills, many young women feel that being slimmer can change the way they feel about themselves. The obesity rate among young Chinese women in Singapore is only 4. 2 percent. However, Singapore is ranked fifth in per capita consumption of diet pills in the world.

Evidence For Prescribing Fluoride Varnishes Health And Social Care Essay

Dental cavities is one of the most common disease processes across all populations throughout the universe and a cardinal factor in dental hurting and tooth loss. Caries is a procedure that can happen on any tooth surface in the oral cavity where alveolar consonant plaque is able to develop over clip. Bing a biofilm, plaque contains many different microorganisms that work together and are continually active. Some of these bacteriums are able to ferment soluble saccharides to bring forth acids, ensuing in a bead in sourness below pH 5 and hence doing demineralization of the enamel surface. Acid is neutralized by spit and the demineralization procedure halted, as the pH rises, mineral may be regained and remineralisation can happen. If the cumulative consequence of these procedures is a net loss in mineral, a carious lesion will be observed. The carious procedure is hence natural and can non be prevented nevertheless with suited intercession, the patterned advance into a seeable lesion can be avoided1. The bar of cavities is considered more cost-efficient than intervention and is hence considered a priority2. Fluoride varnishes since the 1960 ‘s have been clinically utilized for this reason17,18. Application of concentrated fluoride varnishes to tooth surfaces consequences in the formation of Ca fluoride. As the sourness of the environment additions, a greater sum of enamel disintegration occurs and hence an copiousness of ionic Ca allows for a considerable sum of Ca fluoride formation. Significant precipitation of spherical globules of Ca fluoride in dental plaque and unaccessible countries is of great benefit leting for important remineralisation due to the high concentration of free ionic Ca available3. Fluoride besides has a direct consequence on bacterial metamorphosis ( see appendix 4, table 1 for details16 ) .MethodOf the three surveies reviewed, one was carried out in Sweden4, one in Florida5 and one in San Francisco6. In these trials,1375 participants were studied ru ning from ?1.8 to 16 old ages old and followed for periods between 9 months and 3 old ages. Each survey had a specific purposes, one focused on a school based fluoride varnish programme and the patterned advance and incidence of approximal cavities from high, medium and low socio-economic backgrounds4. Another concerned the efficaciousness of fluoride varnish in add-on to reding in the bar of early childhood caries6, whilst the concluding survey evaluated the consequence of fluoride varnish on enamel cavities patterned advance in the primary dentition5. The chief features of each survey and their consequences are displayed in Appendices 14, 25 and 36. Randomization was used to delegate participants into each of the groups in all tests and one study6 outlined the allotment technique used. Two surveies were individual blind4,5 where the tooth doctor was incognizant of the group allotments and one was conducted as a dual blind trial6. All surveies used Duraphat ( 5 % Sodium Fluoride 22,600 F-ppm ) with two studies5,6 using varnish to all tooth surfaces and the 3rd study4 using varnish merely to approximal surfaces from the distal surface of the eyetooths to the mesial surface of the 2nd grinders. Two surveies stated the sum of fluoride varnish to be used ; 0.1ml per arch6 and ?0.3ml in total4. Examination techniques differed amongst the three selected surveies. One conducted a ocular scrutiny three times6, another conducted four overall bitewing radiogram at baseline and after the trial4. The 3rd conducted both radiographic bitewings and a ocular scrutiny besides at baseline and following the test, explicitly discoursing the method6. All experiments experienced a loss of participants to some grade. Weintraub et al.6 concluded 67 % of participants enrolled at baseline saw the survey through, the test conducted by Autio-Gold et al.5 retained 81 % of initial participants. In the concluding experiment by Sk & A ; ouml ; ld et al.4, 89 % of topics completed the test. Ultimately, all surveies agreed fluoride varnish is of significance in forestalling caries4,5,6 and may be effectual in change by reversaling cavity and crevice enamel lesions5. Findingss were assessed in footings of statistical significance and all three4,5,6 gave P values. Differences in measuring lesions clinically can be seen. Sk & A ; ouml ; l et al.4 used a self-devised numbered marking system to find cavities incidence and patterned advance of carious lesions. Weintraub et al.6 used the NIDCR diagnostic standards for dental caries7 for the appraisal of cavitated, decayed and filled surfaces on primary dentitions and auxiliary criteria8 to name pre-cavitated lesions. Finally Autio-gold et al.5 utilised a marking system9 which differentiates between active and inactive enamel carious lesions.DiscussionAlthough all surveies statistically support the usage of fluoride varnish in the bar of cavities, the methodological analysis of each demand to be considered before any decisions c an be drawn. Double blind randomized control tests are considered the ‘gold criterion ‘ in footings of survey design10 and minimise prejudice. In all of these tests, the tooth doctors were incognizant of patient allocated groups nevertheless in two4,5, the participants were cognizant. This could hold led to bias in those surveies as cognizing they were portion of a test with regular follow up periods, patients may hold been more self-aware with respect to their unwritten wellness and hence take more preventive steps compared to groups with fewer visits. Overall this consequence may give the feeling that a more frequent application of varnish reduces cavities incidence. Sample size demands to be taken into history as a larger cohort will give a more accurate representation of the population, doing Sk & A ; ouml ; l et al.4 the most representative of the three tests. Gender was reasonably every bit distributed in both varnish and hazard groups. This is of significance as it has been shown that females are by and large more compliant than males11 and therefore are more likely to brush on a regular basis, maintaining to the survey design. Bias in this illustration is hence reduced as females are every bit distributed across all groups. Weintraub6 and Autio-Gold5 did non advert gender distribution and hence lend themselves to this prejudice. When sing the clip period in which tests are conducted, a greater clip graduated table allows for a more comprehensive result. Potential side effects of fluoride varnish are more likely to go evident and its anti cavities consequence can be reviewed for any possible alterations as there may be a critical period for which it has consequence. Again, Sk & A ; ouml ; l et al.4 conducted the longest test at 3 old ages and hence in footings of clip period, have the most accurate consequences for effects of fluoride and its side effects, of which they found none. Weintraub et al.6 besides used a sensible clip period and would demo any side-effects or critical periods for fluoride applications, merely one kid in the group having fluoride four times a twelvemonth developed an ulcer on their cheek which had resolved at the following followup. There is no grounds to back up unwritten ulcerations as a consequence of fluoride varnish application. The test conducted Autio-Gold5 was over a shorter period and hence compared to Weintraub6 and Sk & A ; ouml ; l4, can non be as conclusive in critical periods of application and side effects. Follow up periods are of relevancy as changing frequences of application can be assessed for effectivity. Sk & A ; ouml ; l et al.4 utilised the greatest figure of groups with the most differing frequences to set up the most effectual intervals. The method in which fluoride varnish was applied varied and one specific survey, Autio-Gold5, failed to stipulate whether application on all tooth surfaces at the 2nd follow up occurred, as at the baseline. Besides the sum of fluoride varnish applied is non stated as in the two other studies4,6. Therefore the survey can potentially be classified as inconsistent and cogency of the consequences questionable. Application of the varnish was conducted in similar ways across all three tests nevertheless Weintraub et al.6 used ?66 % of the fluoride varnish than Sk & A ; ouml ; l et al.4 and it must be considered that a higher dose of fluoride may hold a greater preventive consequence. The locations in which the surveies took topographic point differ. Sk & A ; ouml ; l et al.4 conducted their probe in Sweden where H2O is fluoridated. Socio-economic position is associated with unwritten health12 and in this survey, the low hazard group had a high socio-economic position. The extra factor nevertheless, is that the location of this group is besides in an country of H2O fluoridization ten times higher than that of the medium or low hazard groups. It has been shown that fluoridization reduces cavities incidence13 intending these participants technically received an increased dose and therefore may hold influenced the consequences to demo a decreased effectivity of fluoride varnish. In the other two studies5,6 this variable was controlled and Weintraub et al.6 ensured participants resided in the country for at least 2 old ages. Age of participants is of importance as striplings in the Sk & A ; ouml ; l et al.4 survey are responsible for their ain unwritten hygiene and it has been shown that 25 % of 14-year-olds do non on a regular basis brush their teeth14,15. Consequences can hence be influenced in this test. If ?25 % participants did non brush on a regular basis, theoretically it would do increased cavities incidence in these people compared to the other 75 % of the cohort and finally give the feeling fluoride varnish has a lesser consequence than in world. Autio-Gold5 and Weintraub6 used primary5 and pre-school6 kids where parents and defenders are more likely to conform to the survey design and better the cogency of the consequences. Consequences were based on the findings of the testers therefore their determinations are important. Autio-Gold5 and Weintraub6 both calibrated testers nevertheless Sk & A ; ouml ; l et al.4 did non advert any dependability apart from re-examining radiogram after 2 months, the consequences of which, are non published. There is hence a possibility of inaccuracy in cavities diagnosing at each follow up, which would give either a greater or lesser perceived fluoride consequence depending on tester tolerance. Caries diagnosing methods vary, ideally a radiographic and ocular scrutiny should be conducted as white topographic point lesions and early cavities can non be seen radiographically, the attack taken by Autio-Gold et al.5. Weintraub et al.6 used merely ocular scrutinies and hence, although improbable, potentially leting for non-cavitated lesions to be missed. Sk & A ; ouml ; l et al.4 took merely radiographs nevertheless this was appropriate as approximal cavities can be merely be s een in this manner. Deviations in protocol can be seen in two surveies. In Sk & A ; ouml ; l et Al. ‘s4 test, all groups received an extra application of fluoride every one-year visit including the control group. Realistically the control group hence received intercession and perchance affected the consequences. Weintraub et al.6 experienced a more terrible divergence. For 10 months, participants received a placebo varnish alternatively of the active merchandise and merely one kid received all four planned applications. Besides 21 applications could non be confirmed as active and were assumed placebo. This may hold given the feeling of a greater good consequence of fluoride varnish if the placebo was active. Any long term positive or negative effects can therefore non be concluded with every bit much assurance as the other two trials4,5 as there was a interruption in the application of active merchandise. A Cochrane systematic review19 determined that on norm, fluoride varnish reduced cavities in the deciduous teething by 33 % and by 46 % in the lasting teething.DecisionIn decision, holding considered the grounds base for the usage of fluoride varnish and evaluated the advantages and disadvantages of all mentioned surveies and their restrictions, fluoride varnish is an effectual method in commanding cavities incidence and patterned advance.RecommendationsFluoride varnish should be indicated in all kids and striplings. Adults with a high cavities hazard should besides be considered, such as those with particular demands, dry mouth or active carious lesions. Children and striplings should have application biannually and grownups with carious lesions or particular demands should hold varnish applied between two and four times yearly. No common or serious inauspicious effects have been reported in any surveies. As a safeguard fluoride varnish is contraindicated in terrible asthmatics, ulc erative gingivitis and stomatitis. Besides allergy to seal components is an obvious contraindication.MentionsKidd EAM. Introduction. In: Kidd EAM editor. Necessities of Dental Caries. 3rd erectile dysfunction.

Fukuzawa lived during one of the most incredible changes in Japanese history, the Meiji Restoration, and was one of the biggest supporters for opening the country to foreign thought and civilization. Fukuzawa dreamed of a nation were the strict class system did not exist and a nation that welcomed foreign influence openly and warmly. Fukuzawa writes, â€Å"The final purpose of all my work was to create in Japan a civilized nation as well equipped in the arts of war and peace as those of the Western world. I acted as if I had become the sole functioning agent for the introduction of Western learning† (214).

To Regulate or Not to Regulate (Pick an area to apply the question to Research Paper

To Regulate or Not to Regulate (Pick an area to apply the question to it, as per the instructions) - Research Paper Example Many say absolutely; while others say definitely not. It is the intention of this work to outline reliable viewpoints to determine if self regulation is even a feasible contention. It is the overall determination of this research that it is not. Regulation of the banking system is essential. Reforms are certainly called for, but completely â€Å"free banking† would be foolish and economically dangerous to the United States. Regulations were initially introduced to unify the banking industry, but, also, to protect the monies of the people and to encourage universal honesty in banking business practices. Today the regulations have been altered, reformed, and added to accommodate the changing times in comparison to the earliest appearances and the opinions about those regulations placed on the banking industry have been heavily debated and will probably continue to be so for a long time to come. There are viewpoints that stretch the entire spectrum of the topic. There are those that believe that there should be absolutely no regulations dedicated to banking. There are those that feel that the regulations need to be stronger and even stricter that they currently are. There are, also, those that remain somewhere in the middle on the issue. They feel some regulations are definitely in order, but are not certain if even more restrictions will actually solve the problems within the banking industry, or just ma ke things much worse. So which viewpoint is right? Can the banking system be self regulated? Will the viewpoints ever find a compromise that result in a solution that is effective and successful? Would anyone feel comfortable depositing their hard earned money in a bank that did not possess FDIC insurance? Without that insurance and the regulations involved your money could become leveraged while the bank takes financial risks. If something goes wrong and that money was lost banks would have little incentive or responsibility to you or that money.("Office

Trace the complex seemingly contradictory relationship between the Essay

Trace the complex seemingly contradictory relationship between the exotic 'newness' of primitivism and the urge to explore ethnic or national roots - Essay Example The canvas included portraits, still lifes, landscape, verve, nudes of spontaneity with rich textured surfaces, bold colors and lively linear patterns. The Fauves used startling contrasts of emerald green, vermilion, vivid orange and cerulean blue in bold strokes and sweeping brush strokes. Fauves desired to use both sides of Expressionism. Outward expression was expressed in the bold release of internal thoughts in wild color, brutal and powerful brushworks and the depiction of inward expression awakened the emotion of the viewers through the designs. There was no official organization of Fauve painters. The laxity of stylistic affinities and personal connections led the Fauve movement to disintegrate as soon as the art form emerged. The artists who followed Fauve principles departed from the idea and followed their own personal styles. The short tenure of Fauvism however made remarkable contribution to the art of painting by experimenting expressive, structural and aesthetic capabi lities. Henri Matisse was a prominent figure among the Fauve group.1 German Expressionism evolved from Fauvism and moved beyond the art in compelling, dramatic portrayal of people and scenes. Three main groups of German Expressionism were Die Brucke, Der Blaue Reiter and Die Neue Sachlichkeit. Der Blaue Reiter  or the Blue Rider group took shape in Munich which is home of avant-garde New Artist Association. The most famous artist of Der Blaue Reiter was Wassily Kandinsky and Franz Marc. Der Blaue Reiter was a loose association with artists like Paul Klee, August Macke and Gabriele Munter. The objective of the Blue Rider was to infuse art with spiritual values with the use of color. Blue riders mean vague. Marc instilled the idea that animal had innocence and so it is superior to human. The Blue Rider Expressions are mild forms which are seen in Cossacks by Kandinsky, Little Blue Horse and The Little Blue Horses by

Financial statement analysis Essay Example | Topics and Well Written Essays - 750 words

Financial statement analysis - Essay Example This implies that the firm has less liquidity as compared to the industry generally. However, both ratios are below the Third quartile and therefore there are companies in the industry with higher liquidity ratios than S&S Air. The company may therefore have less predictable cash flows and less access to short-term borrowing (Fridson, & Alvarez, F., 2002). A quick ratio of 0.37 is slightly higher than the industry median and this has the meaning that S&S has about the same value of inventory as the Current Liabilities. Since the company has about the same inventory as the industry median, its inventory to current liabilities ratio is more or less the same as the median for the industry. The turnover ratios as compared to the industry median are all higher and even higher than the upper quartile. This implies the efficiency of S&S Air than the whole of the industry. On the other hand, the leverage ratios are all below the industry median depicting that the firm is less dependent on debt than related companies are. In addition, the Profit Margin for the company is equal to that of the industry median while the ROA and the ROE are all above the industry median as well as the lower quartile. In short, the performance of the airline is good despite the liquidity ratios indicating that close monitoring is necessary in its operations. Using ROA of 10.61% and the retention ratio, we will be able to get the internal growth rate. The constant b= $9,233,930/$1,845,242 = 5.004; Using the internal growth rate equation: Internal growth rate = (0.1061 Ãâ€" 5.004) / [1 – (0.1061 Ãâ€" 5.004)] =113.18%. we go further to find the sustainability growth rate using ROE of 19.31% as follows; Sustainable growth rate = (0.1931 Ãâ€" 5.004) / [1 – (0.1931 Ãâ€" 5.004)] = 28.65. Without outside financing of any sort, the company is able to achieve a growth rate of 113.18% and the growth rate would even be enormously higher when it gets funding externally (Robinson,

Licensed Futurist Essay Example | Topics and Well Written Essays - 750 words

Licensed Futurist - Essay Example In his DVD, An Inconvenient Truth, he talks about how our entire world is changing. The challenge for Gore is that the people who need to listen and do something about it on a larger scale, are turning a deaf ear. Many so-called scientists want to say that there is no such thing as Global Warming. However, everyone is experiencing climate changes. We have more damaging storms and many areas that should have snow in the winter have spring days. In some areas, the summers are hotter than ever before and we are losing our oceans. We are not paying attention to this because we do not think that it is affecting us. However, everything that happens to the planet will have an effect on us eventually. Another area where we are not watching is what is happening in technology. With cell phones alone, we have a device that baby sits, takes away time from the family and does everything but get up and dance; who knows, someone may be working on that one right now! We are told that many discoveries in telecommunications and other technology are good for us. A prediction that "there will be intelligent electronic systems almost everywhere" (Hall, 2007, p. 1) is a common prediction. Why? Because ewe are becoming so advanced with our technology that it is difficult to embrace all of it at once. One prediction in this area that we have already realized is the Internet connections anywhere we go. Many restaurants, hospital waiting rooms, even Burger King has a wireless connection today. Although this is a great idea, when we embrace it to the fullest, we will move away from our children and families in favor of talking on the phone or being on the computer most of the time. According to Rub ner (2010), some experts predict that we will be wearing mobile electronics in our clothing; Rubner says we will not need computers eventually because we will be wearing them. Hall adds to what Rubner says and we can expect live

Internet Protocol (VoIP) Technology

Internet Protocol (VoIP) Technology Abstract Voice over Internet Protocol (VoIP) technology has come of age and is quickly gaining momentum on Broadband networks. VoIP packetizes phone calls through the same routes used by network and Internet traffic and is consequently prone to the same cyber threats that plague data networks today. It presents lower cost and greater flexibility for a venture but presents considerable security challenges. Many solutions for VoIP security are projected, however these solutions should take into account the real-time constriction of voice service and their methods be supposed to address probable attacks and overhead related with it. One of these solutions is to make use of Firewalls, which implement a security strategy by examining and straining traffic arriving or leaving from a protected network. This is normally done by evaluating an incoming packet to a set of policies and performing the corresponding rule action, which is accept or reject. Undesirably packet examinations can require considerable interruptions on traffic due to the difficulty and size of policies. Consequently, improving firewall performance is significant for the VoIP networks. In this paper, we propose a new firewall deign that is able to dynamically update firewall policy based on Neural Network and achieve packet examinations under rising traffic loads, higher traffic speeds, and stringent QoS necessities. The design consists of several firewalls configured in parallel that jointly impose a defense strategy. Every firewall outfits part of the rule and incoming packets is processed through all the firewalls concurrently. Once the neural network is trained, it continuously updates the firewall policy using the selected parameters to perform its evaluation. Since many firewalls are utilized to process each packet, the proposed parallel firewall system has considerably lower delays and a higher throughput than other firewalls. Introduction Voice over IP the transmission of voice over traditional packet-switched IP networks is one of the hottest trends in telecommunications. Although most computers can provide VoIP and many offer VoIP applications, the term â€Å"voice over IP† is typically associated with equipment that lets users dial telephone numbers and communicate with parties on the other end who have a VoIP system or a traditional analog telephone. (The sidebar, â€Å"Current voice-over-IP products,† describes some of the products on the market today.) As with any new technology, VoIP introduces both opportunities and problems. It offers lower cost and greater flexibility for an enterprise but presents significant security challenges. As with any new technology, VoIP introduces both opportunities and problems.. Security administrators might assume that because digitized voice travels in packets, they can simply plug VoIP components into their already secured networks and get a stable and secure voice network. Quality of service (QoS) is fundamental to a VoIP networks operation. A VoIP application is much more sensitive to delays than its traditional data counterparts. Latency turns traditional security measures into double-edged swords for VoIP. Tools such as encryption and firewall protection can help secure the network, but they also produce significant delay. Latency isnt just a QoS issue, but also a security issue because it increases the systems susceptibility to denial-of-service attacks. To succeed in a VoIP network, a DoS attack need not completely shut down the system, but only delay voice packets for a fraction of a second. The necessary impediment is even less when latency-producing security devices are slowing down traffic. As described in the introduction, parallelization offers a Scalable technique for improving the performance of network firewalls. Using this approach an array of m firewalls processes packets in parallel. However, the two designs depicted in differ based on what is distributed: packets or rules. The design was Consisted of multiple identical firewalls connected in parallel, each firewall j in the system implements a local policy Rj where Rj = R. Arriving packets are distributed across the firewalls for processing (one packet is sent to one firewall), allowing different packets to be processed in parallel. Since each packet is processed using the policy Rj = R, policy integrity is maintained. A neural network is a group of interconnected nodes. The well-known example is the human brain, the most complicated and difficult neural network. We can make very fast and reliable choice in portion of a second. In the face of the clear neatness of usual thinking, outcome are usually not-white and -black or binary, but quite engage a broad diversity of alert and secreted inputs, we have an wonderful facility to recognize well-known patterns as well as extraordinary patterns more or less directly, the neural network approach effort to reproduce the way humans visually the usual consumer speedily studies to identify spam from correct connection. The reason for this is generally since we illustration our brains both on reason to a broad variety of message content and the brain learns to create lightning-fast, very exact guess. The capacity of utilizing packet changed networks as a transmit standard for real-time tone of voice connections has drawn broad awareness among both research and possible communities alike. The current progress in speech conventions and high speed information communication technology hold up the notice in equipment such as voice over Internet protocol (VoIP), the mathematical character of information interchange and the energetic routing method engaged in packet-switched networks outcomes in an unbalanced network delay (jitter) practiced by IP packets. [chris miller]. Although a data-parallel firewall can achieve higher throughput than a traditional (single machine) firewall, it suffers from two major disadvantages. First, stateful inspection requires all traffic from a certain connection or exchange to traverse the same firewall. Successful connection tracking is difficult to perform at high speeds using the data-parallel approach Second, distributing packets is only beneficial when each firewall in the array has a significant amount of traffic to process (never idle), which only occurs under high traffic loads. In order to understand parity in a carrier network maintaining secrecy, the studying techniques to know excluded traffic from partial information, such as the header information and show pattern of a series of packets. The propose a traffic credit technique for a direct request which uses mathematical information such as incidence of packet coming. This method is to be used for stop idea by recognize traffic generate by not only VoIP but video request as well. By using this method, travel that is clearly mediator excluded is not needed, the quality of traffic that is classified into best services, such as urgent situation message and moving sharing, is certain, and, for best effort services, suitable operation are perform so that capital can not be busy by a few edge, so as to understand fairness in symbol services. This advance is to applications that generate traffic from the presentation of the traffic. It can be underground into the following three types regarding the granularity of the observed traffic. [Toshiya Okabe Tsutomu Kitamura 2006]. Transaction-level behavior This approach is a system focus on the skin of an application-level action, such as an HTTP request message, and its response, an HTTP response message or MAIL message. With this progress, a request is indirect from the change patterns, the size of each message. A method to order maintain by the time-series changes in the size of messages. These techniques are useful for sense a signal protocol, but are not suitable for discovery of real-time message traffic whose features are boring and last for a fairly long time. [Toshiya Okabe Tsutomu Kitamura 2006] Flow-level behavior This method is to make out an application from mathematical information such as the inter-arrival time, period of the run, packet size. Here, a run is defined as a sequence of packets having a common source address, source port, destination address, destination port and transport protocol. It is extract skin of size data message request flows, such as HTTP, FTP and SMTP graceful from side to side a network, in order to create workload for a network simulator and classify traffic into three lessons, bulk data message such as FTP, informal message. [Toshiya Okabe Tsutomu Kitamura 2006] Packet-level behavior This is techniques that identify a request from the header or load of a single packet. A group method mainly based on port facts has been used but its efficiency has been lost due to the arrival of P2P applications that illegitimately use chance port numbers and port numbers for HTTP to traverse a Firewall. [Toshiya Okabe Tsutomu Kitamura 2006]. Average packet length and variation The result of extract skin correlated to the normal packet size and difference in packet size. Difference in packet size here indicates the number of types of packet size for a request whose packet size is fixed. It is the result of take out the skin of voice applications. The packet size of the voice application is lesser than that of the other application. [ Takayuki Shizuno 2006] As with any new knowledge, VoIP introduce both opportunity and problems. It offers lesser cost and greater give for an project but presents significant security challenge. Security administrator strength suppose that because digitized voice actions in packets, the plug VoIP mechanism into their previously protected networks and get a stable and secure voice network address translation (NAT), and most VoIP mechanism have counterpart in data network, VoIPs presentation stress mean you must extra ordinary network software and hardware with special VoIP mechanism. Packet network depend on many configurable bound: IP and physical addresses of say terminal of routers and firewalls. VoIP networks add specific software, to place and route calls. Many network bound are recognized with passion each time a network part is restart or when a VoIP phone is restart or added to the network.. So many nodes in a VoIP network have dynamically configurable bound; But VoIP systems have much stricter presentation constraint than data networks with important implication for security. [ Takayuki Shizuno 2006]. Quality-of-service issues Quality of service is basic to a VoIP networks process. A VoIP request is much more responsive to delay than its customary data matching part. In the VoIP language, this is the latency problem. Latency turns conventional safety measured. Tools such as encryption and firewall defense can help secure the system, but they also set up important delay. Latency isnt just a QoS issue, but also a safety issue because it increases the system weakness to denial-of-service attacks. To do well in a VoIP network, a DoS attack need not totally shut down the system, but only delay voice packets for a part of a second. The necessary let is even less when latency-producing security devices are slowing down traffic. Another QoS issue jitter, refers to no uniform delays that can cause packets to turn up and be process out of series. The Real-Time Transport Protocol (RTP), which is used to move voice media, so packets received out of order cant be reassembled at the move level, but must be rearrange at the request level, introduce major above your head. When packets turn up in order, high jitter causes them to arrive at their target in spurts. To control jitter, network expensive can use buffers and implement QoS-supporting network elements that let VoIP packets when larger data packets are listed in front of them. The buffer can use one of several plans to resolve when to let go voice data, counting several scheme that adapt the payout time also encompass packet loss. In addition to the usual packet loss issue related with data networks, even VoIP packets that reach their target can be make useless by latency and jitter. [thomas j. walsh and d. richard kuhn ]. Project Background Neural network is the bury order growing fast in current years. It is jointly of a massive deal of easy giving out units of neuron with providing connect as a neural network. It can replicate the information distribution task of human being brain, with huge talent of nonlinear estimate, consecutively storage, large-scale similar development, and self-training lessons. The information distribution in the neural network is recognizing by the communication between the neurons, and the storage of data and in progression as increase physical interconnection of the network parts. [, a. shelestov, v. pasechnik, a. sidorenko, n. kussul , 2006]. A parallel firewall (also called a load-balancing firewall) is a scalable approach for increasing the speed of inspecting network traffic. As seen in figure .the system consists of multiple identical firewalls connected in parallel. Each firewall in the system implements the complete security policy and arriving packets are distributed across the firewalls such that only one firewall processes any given packet. How the load-balancing algorithm distributes packets is vital to the system and typically implemented as a high-speed switch in commercial products. Although parallel firewalls achieve a higher throughput than traditional firewalls and have a redundant design, the performance benefit is only evident under high traffic loads. Furthermore, stateful inspection requires all traffic from a certain connection or exchange to traverse the same firewall, which is difficult to perform at high speeds. This paper introduces a new scalable parallel firewall architecture designed for increasing network speeds and traffic loads. The design consists of multiple firewalls where each firewall implements only a portion of the security policy. Since the policy is divided across the firewalls, rule distribution guidelines are provided that maintains integrity, ensuring the new parallel design and a traditional single firewall always reach the same decision. Unlike the previous parallel design, When a packet arrives to the new architecture it is processed by every firewall in parallel, thus the processing time required per packet is reduced. Simulation results for the new architecture (consisting of four firewalls) yielded a 74% reduction in processing time as compared to other parallel firewall designs. Furthermore, the proposed architecture can provide stateful inspections since a packet is processed by every firewall. Therefore, the new parallel design is a scalable solution that can offer better performance and more capabilities than other designs. In list-based rule symbol, when packets arrive at a firewall, it is in sequence check against the system in the rule list until a match is found or attainment the end of the list. Then, the parallel action is applied to mass or pass the packet. To make the policy complete of match is always found for each packet, the computational difficulty of the sort process depends on the length of rule as the depth of result a matched rule in the rule list. Apply more composite policy can result in major traffic wait which is not only a presentation block in high speed environment but also can make it weaker to rejection of service attacks. Moreover, attractive the filter time is more difficult for multimedia applications that require firm quality of service promise. Although hardware solutions can very much decrease the packet giving out time, they are costly for large policy and improvement hardware may not be suitable in inheritance systems. on the other hand, better data structure for inner policy symbol and better search mechanism have been planned to provide relatively and effective solution to benefit on hand hardware systems. The rules are group to allow multidimensional search by at once eliminate multiple rules with few comparison. While tries have shown great agree in improving the search time, the storage condition and difficulty in maintain try and policy honesty increases as more rules . Moreover, a policy trie does not take into report the traffic personality. In a method for trie sorting is proposed that sustain the policy honesty while reorder rules for unreliable traffic situation. The number of contrast as compare to the original trie. Traffic-aware optimization of list-based firewalls has been addressed in rules are assigned matching probability that depend on the traffic information. Other firewall models have been planned to signify and analyze policy whether for central or distributed firewall architectures with main focus on identify rule conflicts and variance; Wireless local (WLAN) and wireless personal (WPAN) area networks are being used increasingly to implement VoIP forces. The main drives for using these architectures are user mobility. Behind realible real-time repair is one of the major concerns for generally use of VoIP in these wireless IPbased networks and safety is now getting the notice of researchers. The security and efficiency are consisting requirements. [El-Sayed M. El-Alfy and Shokri Z. Selim 2007] Literature Review Introduction: Literature Review is the process of finding information for help on searching for resources on the Internet. Reading intensively in the chosen topic area is essential, but the task can prove daunting if they do not approach it in a systematic way. The continuous number of high-profile Internet security breeches reported in the mass media shows that despite an emphasis on security processes that there is still a gap between theory and practice. Not only is there a need to develop better software engineering processes but also theoretical security improvements need to find their way into real systems. Software design patterns are defined as â€Å"descriptions of communicating objects and classes that are customized to solve a general design problem in a particular context†. As software design patterns have proven their value in the development of production software, they are a promising new approach to help in both the theoretical development and practical implementation of better security processes. First, many/most software developers have only a limited knowledge of security processes and patterns are a proven way to improve their understanding. Second, patterns work against â€Å"reinventing-the-wheel† to promote learning best practices from the larger community to save time, effort, and money with easily accessible and validated examples. Third, code can be reused since the same security patterns arise in many different contexts Investigating existing resources in our area of research will generally cover three areas: Exploratory investigations, as part of the development and evaluation of possible topics in an area Investigation is some depth, sufficient to support a formal research and dissertation proposal Complete research that is described in the literature / research section of the dissertation. [from Writing the Doctoral Dissertation, To Author names] 2. Related Research Work Available: Wireless local (WLAN) and wireless personal (WPAN) area networks are being used progressively to implement VoIP services. The main motivation for using these architectures are user mobility, setup flexibility, increasing transmission rate and low costs, despite this convergence depends on the answers of several technical problems Supporting reliable real-time service is one of the major concerns for widely deployment of VoIP in these ireless IPbased networks and security is now receiving the attention of researchers. The problem of offering security to WLAN and WPAN is that security does not come for free and, security and efficiency are conflicting requirements. The introduction of a security mechanism such as the IPSec encryption-engine to overcome these issues impacts directly in the speech quality of established calls and in the channel capacity. Moreover, largely deployed radio technology standards as IEEE 802.11 and Bluetooth used to achieve wireless connectivity have several constraints when delivering real-time traffic, as transmission errors at the channel, introducing delay and loss which with security mechanisms impact can lead to low quality VoIP calls. Although these technologies offer some security mechanisms, they have some flaws which need to be addressed by an additional level of security. In this paper we focus on the IPSec protocol to achieve the data secrecy due to its widely deployment and implementation of many encryption algorithms. During final decades information technology founded on the computer networks take part in an essential role in different areas of human being action. Troubles of huge importance are assigned on them, such as maintenance, communication and mechanization of information processing. The safety level of processed information is able to differ from private and viable to military and state secret. Herewith the destruction of the information secrecy, reliability and accessibility may cause the spoil to its proprietor and contain important unattractive consequences. Hence the trouble of information safety is concerned. Many associations and companies expand safety facilities that need important aids. In additional, the impracticality of creating wholly protected system is a recognized fact – it will always hold faults and  «gaps » in its understanding. To guard computer systems such familiarized mechanisms as classification and verification, methodologies of the delimitation and limit of the access to data and cryptographic techniques are applied. But they hold following drawbacks: †¢ Disclosure from interior users with spiteful purpose; †¢ Complexity in access separation caused by data sources globalization, which cleans away difference between personal and foreign topics of the system; †¢ Diminution of efficiency and communication complexity by reason of methods for access control to the sources, for occasion, in e-commerce; †¢ Effortlessness of passwords description by crating arrangements of simple users relations. Hence classification and audit systems are utilized beside with these methods. between them are interruption. Intrusion Detection Systems (IDS). IDS are generally separated to systems detecting previously identified attacks (mishandling exposure systems) and variance exposure systems registering the life cycle differences of the computer system from its usual (distinctive) action. Besides, IDS are divided to network-based and host-based category by data source. Network-based IDS examine network dataflow, caring its members, almost not moving the output of their work. Network-based systems do not utilize data about progression from divide workstation. A firewall is a mixture of hardware and software used to put into practice a security policy leading the flow of network traffic between two or more networks. In its simplest form, a firewall acts as a safety barrier to control traffic and manage links between internal and external network hosts. The actual means by which this is able varies and ranges from packet sort and proxy service to stateful examination methods. A more difficult firewall may hide the topology of the network it is employed to keep, Firewalls have recognized to be useful in trade with a large number of pressure that create from outer a network. They are becoming ever-present and necessary to the action of the network. The constant growth of the Internet, coupled with the increasing difficulty of attacks, however, is placing further stress and difficulty on firewalls design and management. . [ Subrata Acharya, Jia Wang, Albert Greenberg 2006] Furthermore, the need to deal with large set of varied safety policy and rules impose additional load on firewalls, thus depiction the presentation of the firewall highly serious to enforce the network safety policy. In this context, the defense that a firewall provides only the policies it is configured to execute, but evenly importantly the speed at which it enforces these policy. Under attack or deep load, firewalls can simply become a bottleneck. As the network size, bandwidth, and giving out power of networked hosts carry on increasing, there is a high demand for optimizing firewall operation for improved performance. [ Subrata Acharya, Jia Wang, Albert Greenberg 2006] Multi-dimensional firewall research group of people to focus on mounting various optimizations to make firewalls more resourceful and steady. In spite of significant progress in the design of firewalls, the techniques for firewall optimization remains static and fail to get used to to the always varying dynamics of the network. This is frequently due to their failure to take into account the traffic individuality by the firewall, such as source and purpose, service requests and the resultant action taken by the firewall in reply to these requests. Moreover, current firewall designs do not support adaptive difference discovery and counter measure device. As a result, they run the risk to become unbalanced under attack. The object of this paper is to address the above failing and develop a sound and effective toolset to hasten firewall operation and adapt its performance to the dynamically altering network traffic individuality. Achieve this goal, however is tough, as the number of policy and safety rules a firewall has to enforce for enterprise network. In addition, there is a need for preserve high policy addition. This is further compounded by the limited resources of firewalls relation to the increased ability of the network to process and forward traffic at very high speed.

In this section data parallel [Carsten Benecke,1999] and function parallel designs [Errin W. Fulp,2002] for parallel firewalls are explained. Similar to their distributed computing descriptions necessitate, data parallel partition the information set across the array of firewalls, while function parallel distributes the work set across the array of firewalls. The data parallel technique is a scalable substitute to a single firewall that permits for better throughput potentials. Function parallel techniques can diminish the dispensation time necessary on any firewall node yielding enhanced presentation. In addition, unlike data parallel designs, the proposed function parallel architecture can offer stateful assessments. This proposal shows that function parallel designs are scalable solution that can offer better performance and more facilities than other designs. Parallel Firewall Architecture: Function Parallel Firewall [W. Fulp and Ryan J] consists of multiple firewalls coupled in parallel and a gatedevice, as shown in figure. Every firewall in the system outfits a local strategy, where incoming packets are disseminated across the firewalls for processing (one packet is sent to one firewall), permitting different packets to be processed in parallel. Because every packet is processed by the policy, reliability is maintained. The common operation of the scheme can be described as follows. When a packet reaches to the function-parallel system it is promoted to all the firewall and the gate. Each firewall processes the packet with its local policy, as well as any state information. The firewall then signals the gate representing either no match was found, or offers the rule number and action if a match was found. As local policies are a division of the original, a no-matchis a suitable answer and is necessary for the function-parallel design. The gate stores the outcomes and establishes the final action to achieve on the packet using the Firewall rule. Parallel Firewall System Components A function parallel system consists of a collection of firewall nodes. Packets are replicated to all firewall nodes as they go into the system. Policies must be disseminated across the system such that they specify an accept set identical to the original accept set and no local policys accept set can overlap another local policys accept set. The received packets are then combined into one stream to arrive at the destination. A control plane is also essential to permit common system management. Firewall Nodes The firewall nodes contain a network interface card for every network input and control plane. This design implements the firewall nodes as PCs running the Linux operating system with a kernel that supports iptables. It must be stated that iptables was selected for an profitable feature of provisional rule dispensation. By default there are built-in sets of policies called chains divided by whether they hold traffic bound for procedures pay attention on local input devices, proposed for routing throughout the system to another network or outbound and supplied from a local procedure. In addition iptables has support for user defined chains. The user defined chains can be called if a packet matches a rule in a sequence. Packet Duplicator Packet Duplicator is essential on all links which will input traffic into the system. In Ethernet networks packet duplication is easily achieved with a network hub because any packets arriving on a hub port are copied to all other hub ports. But, in high speed networks hub technology is not presented. The only available devices in high speed networks to attain duplication are network taps. These devices are used for duplicating network traffic, usually used in intrusion detection systems that necessitate network monitoring. Control Plane In a single firewall system, protected customer communication can be offered through the prerequisite of physical existence. To generate a protected technique of management, communication to the collection of firewall nodes can be quarantined on a separate control plane. In the simplest form this entails a separate subnet which all firewall nodes survive on. Component Integration Joining these components into a functional design can be cut down into two network representations. The first utilizes simply one packet duplicator and can simply offer protection for traffic from one source. The second topology allows two networks to communicate bi-directionally through the system. One-Directional System This technique only thinks about packets traveling in one direction; for example, only packets are moving from source to destination. The collection of firewall nodes use the same IP address and MAC address and all will take the incoming network interface card in immoral mode. All but one firewall node will allow existing networking equipment outside of the system to cooperate with no alterations. The firewall node which does respond to user requirements can also be permitted to respond to ICMP ping requests in order to formulate the system additional compatible. For the outgoing network interface cards, any IP or MAC can be used as long as it permits communication with the destination. Bi-directional System The Bi-directional system considers packets moving in both directions; for example, packets traveling from source to destination and then back to source. Set Internet Protocol (VoIP) Technology Internet Protocol (VoIP) Technology Abstract Voice over Internet Protocol (VoIP) technology has come of age and is quickly gaining momentum on Broadband networks. VoIP packetizes phone calls through the same routes used by network and Internet traffic and is consequently prone to the same cyber threats that plague data networks today. It presents lower cost and greater flexibility for a venture but presents considerable security challenges. Many solutions for VoIP security are projected, however these solutions should take into account the real-time constriction of voice service and their methods be supposed to address probable attacks and overhead related with it. One of these solutions is to make use of Firewalls, which implement a security strategy by examining and straining traffic arriving or leaving from a protected network. This is normally done by evaluating an incoming packet to a set of policies and performing the corresponding rule action, which is accept or reject. Undesirably packet examinations can require considerable interruptions on traffic due to the difficulty and size of policies. Consequently, improving firewall performance is significant for the VoIP networks. In this paper, we propose a new firewall deign that is able to dynamically update firewall policy based on Neural Network and achieve packet examinations under rising traffic loads, higher traffic speeds, and stringent QoS necessities. The design consists of several firewalls configured in parallel that jointly impose a defense strategy. Every firewall outfits part of the rule and incoming packets is processed through all the firewalls concurrently. Once the neural network is trained, it continuously updates the firewall policy using the selected parameters to perform its evaluation. Since many firewalls are utilized to process each packet, the proposed parallel firewall system has considerably lower delays and a higher throughput than other firewalls. Introduction Voice over IP the transmission of voice over traditional packet-switched IP networks is one of the hottest trends in telecommunications. Although most computers can provide VoIP and many offer VoIP applications, the term â€Å"voice over IP† is typically associated with equipment that lets users dial telephone numbers and communicate with parties on the other end who have a VoIP system or a traditional analog telephone. (The sidebar, â€Å"Current voice-over-IP products,† describes some of the products on the market today.) As with any new technology, VoIP introduces both opportunities and problems. It offers lower cost and greater flexibility for an enterprise but presents significant security challenges. As with any new technology, VoIP introduces both opportunities and problems.. Security administrators might assume that because digitized voice travels in packets, they can simply plug VoIP components into their already secured networks and get a stable and secure voice network. Quality of service (QoS) is fundamental to a VoIP networks operation. A VoIP application is much more sensitive to delays than its traditional data counterparts. Latency turns traditional security measures into double-edged swords for VoIP. Tools such as encryption and firewall protection can help secure the network, but they also produce significant delay. Latency isnt just a QoS issue, but also a security issue because it increases the systems susceptibility to denial-of-service attacks. To succeed in a VoIP network, a DoS attack need not completely shut down the system, but only delay voice packets for a fraction of a second. The necessary impediment is even less when latency-producing security devices are slowing down traffic. As described in the introduction, parallelization offers a Scalable technique for improving the performance of network firewalls. Using this approach an array of m firewalls processes packets in parallel. However, the two designs depicted in differ based on what is distributed: packets or rules. The design was Consisted of multiple identical firewalls connected in parallel, each firewall j in the system implements a local policy Rj where Rj = R. Arriving packets are distributed across the firewalls for processing (one packet is sent to one firewall), allowing different packets to be processed in parallel. Since each packet is processed using the policy Rj = R, policy integrity is maintained. A neural network is a group of interconnected nodes. The well-known example is the human brain, the most complicated and difficult neural network. We can make very fast and reliable choice in portion of a second. In the face of the clear neatness of usual thinking, outcome are usually not-white and -black or binary, but quite engage a broad diversity of alert and secreted inputs, we have an wonderful facility to recognize well-known patterns as well as extraordinary patterns more or less directly, the neural network approach effort to reproduce the way humans visually the usual consumer speedily studies to identify spam from correct connection. The reason for this is generally since we illustration our brains both on reason to a broad variety of message content and the brain learns to create lightning-fast, very exact guess. The capacity of utilizing packet changed networks as a transmit standard for real-time tone of voice connections has drawn broad awareness among both research and possible communities alike. The current progress in speech conventions and high speed information communication technology hold up the notice in equipment such as voice over Internet protocol (VoIP), the mathematical character of information interchange and the energetic routing method engaged in packet-switched networks outcomes in an unbalanced network delay (jitter) practiced by IP packets. [chris miller]. Although a data-parallel firewall can achieve higher throughput than a traditional (single machine) firewall, it suffers from two major disadvantages. First, stateful inspection requires all traffic from a certain connection or exchange to traverse the same firewall. Successful connection tracking is difficult to perform at high speeds using the data-parallel approach Second, distributing packets is only beneficial when each firewall in the array has a significant amount of traffic to process (never idle), which only occurs under high traffic loads. In order to understand parity in a carrier network maintaining secrecy, the studying techniques to know excluded traffic from partial information, such as the header information and show pattern of a series of packets. The propose a traffic credit technique for a direct request which uses mathematical information such as incidence of packet coming. This method is to be used for stop idea by recognize traffic generate by not only VoIP but video request as well. By using this method, travel that is clearly mediator excluded is not needed, the quality of traffic that is classified into best services, such as urgent situation message and moving sharing, is certain, and, for best effort services, suitable operation are perform so that capital can not be busy by a few edge, so as to understand fairness in symbol services. This advance is to applications that generate traffic from the presentation of the traffic. It can be underground into the following three types regarding the granularity of the observed traffic. [Toshiya Okabe Tsutomu Kitamura 2006]. Transaction-level behavior This approach is a system focus on the skin of an application-level action, such as an HTTP request message, and its response, an HTTP response message or MAIL message. With this progress, a request is indirect from the change patterns, the size of each message. A method to order maintain by the time-series changes in the size of messages. These techniques are useful for sense a signal protocol, but are not suitable for discovery of real-time message traffic whose features are boring and last for a fairly long time. [Toshiya Okabe Tsutomu Kitamura 2006] Flow-level behavior This method is to make out an application from mathematical information such as the inter-arrival time, period of the run, packet size. Here, a run is defined as a sequence of packets having a common source address, source port, destination address, destination port and transport protocol. It is extract skin of size data message request flows, such as HTTP, FTP and SMTP graceful from side to side a network, in order to create workload for a network simulator and classify traffic into three lessons, bulk data message such as FTP, informal message. [Toshiya Okabe Tsutomu Kitamura 2006] Packet-level behavior This is techniques that identify a request from the header or load of a single packet. A group method mainly based on port facts has been used but its efficiency has been lost due to the arrival of P2P applications that illegitimately use chance port numbers and port numbers for HTTP to traverse a Firewall. [Toshiya Okabe Tsutomu Kitamura 2006]. Average packet length and variation The result of extract skin correlated to the normal packet size and difference in packet size. Difference in packet size here indicates the number of types of packet size for a request whose packet size is fixed. It is the result of take out the skin of voice applications. The packet size of the voice application is lesser than that of the other application. [ Takayuki Shizuno 2006] As with any new knowledge, VoIP introduce both opportunity and problems. It offers lesser cost and greater give for an project but presents significant security challenge. Security administrator strength suppose that because digitized voice actions in packets, the plug VoIP mechanism into their previously protected networks and get a stable and secure voice network address translation (NAT), and most VoIP mechanism have counterpart in data network, VoIPs presentation stress mean you must extra ordinary network software and hardware with special VoIP mechanism. Packet network depend on many configurable bound: IP and physical addresses of say terminal of routers and firewalls. VoIP networks add specific software, to place and route calls. Many network bound are recognized with passion each time a network part is restart or when a VoIP phone is restart or added to the network.. So many nodes in a VoIP network have dynamically configurable bound; But VoIP systems have much stricter presentation constraint than data networks with important implication for security. [ Takayuki Shizuno 2006]. Quality-of-service issues Quality of service is basic to a VoIP networks process. A VoIP request is much more responsive to delay than its customary data matching part. In the VoIP language, this is the latency problem. Latency turns conventional safety measured. Tools such as encryption and firewall defense can help secure the system, but they also set up important delay. Latency isnt just a QoS issue, but also a safety issue because it increases the system weakness to denial-of-service attacks. To do well in a VoIP network, a DoS attack need not totally shut down the system, but only delay voice packets for a part of a second. The necessary let is even less when latency-producing security devices are slowing down traffic. Another QoS issue jitter, refers to no uniform delays that can cause packets to turn up and be process out of series. The Real-Time Transport Protocol (RTP), which is used to move voice media, so packets received out of order cant be reassembled at the move level, but must be rearrange at the request level, introduce major above your head. When packets turn up in order, high jitter causes them to arrive at their target in spurts. To control jitter, network expensive can use buffers and implement QoS-supporting network elements that let VoIP packets when larger data packets are listed in front of them. The buffer can use one of several plans to resolve when to let go voice data, counting several scheme that adapt the payout time also encompass packet loss. In addition to the usual packet loss issue related with data networks, even VoIP packets that reach their target can be make useless by latency and jitter. [thomas j. walsh and d. richard kuhn ]. Project Background Neural network is the bury order growing fast in current years. It is jointly of a massive deal of easy giving out units of neuron with providing connect as a neural network. It can replicate the information distribution task of human being brain, with huge talent of nonlinear estimate, consecutively storage, large-scale similar development, and self-training lessons. The information distribution in the neural network is recognizing by the communication between the neurons, and the storage of data and in progression as increase physical interconnection of the network parts. [, a. shelestov, v. pasechnik, a. sidorenko, n. kussul , 2006]. A parallel firewall (also called a load-balancing firewall) is a scalable approach for increasing the speed of inspecting network traffic. As seen in figure .the system consists of multiple identical firewalls connected in parallel. Each firewall in the system implements the complete security policy and arriving packets are distributed across the firewalls such that only one firewall processes any given packet. How the load-balancing algorithm distributes packets is vital to the system and typically implemented as a high-speed switch in commercial products. Although parallel firewalls achieve a higher throughput than traditional firewalls and have a redundant design, the performance benefit is only evident under high traffic loads. Furthermore, stateful inspection requires all traffic from a certain connection or exchange to traverse the same firewall, which is difficult to perform at high speeds. This paper introduces a new scalable parallel firewall architecture designed for increasing network speeds and traffic loads. The design consists of multiple firewalls where each firewall implements only a portion of the security policy. Since the policy is divided across the firewalls, rule distribution guidelines are provided that maintains integrity, ensuring the new parallel design and a traditional single firewall always reach the same decision. Unlike the previous parallel design, When a packet arrives to the new architecture it is processed by every firewall in parallel, thus the processing time required per packet is reduced. Simulation results for the new architecture (consisting of four firewalls) yielded a 74% reduction in processing time as compared to other parallel firewall designs. Furthermore, the proposed architecture can provide stateful inspections since a packet is processed by every firewall. Therefore, the new parallel design is a scalable solution that can offer better performance and more capabilities than other designs. In list-based rule symbol, when packets arrive at a firewall, it is in sequence check against the system in the rule list until a match is found or attainment the end of the list. Then, the parallel action is applied to mass or pass the packet. To make the policy complete of match is always found for each packet, the computational difficulty of the sort process depends on the length of rule as the depth of result a matched rule in the rule list. Apply more composite policy can result in major traffic wait which is not only a presentation block in high speed environment but also can make it weaker to rejection of service attacks. Moreover, attractive the filter time is more difficult for multimedia applications that require firm quality of service promise. Although hardware solutions can very much decrease the packet giving out time, they are costly for large policy and improvement hardware may not be suitable in inheritance systems. on the other hand, better data structure for inner policy symbol and better search mechanism have been planned to provide relatively and effective solution to benefit on hand hardware systems. The rules are group to allow multidimensional search by at once eliminate multiple rules with few comparison. While tries have shown great agree in improving the search time, the storage condition and difficulty in maintain try and policy honesty increases as more rules . Moreover, a policy trie does not take into report the traffic personality. In a method for trie sorting is proposed that sustain the policy honesty while reorder rules for unreliable traffic situation. The number of contrast as compare to the original trie. Traffic-aware optimization of list-based firewalls has been addressed in rules are assigned matching probability that depend on the traffic information. Other firewall models have been planned to signify and analyze policy whether for central or distributed firewall architectures with main focus on identify rule conflicts and variance; Wireless local (WLAN) and wireless personal (WPAN) area networks are being used increasingly to implement VoIP forces. The main drives for using these architectures are user mobility. Behind realible real-time repair is one of the major concerns for generally use of VoIP in these wireless IPbased networks and safety is now getting the notice of researchers. The security and efficiency are consisting requirements. [El-Sayed M. El-Alfy and Shokri Z. Selim 2007] Literature Review Introduction: Literature Review is the process of finding information for help on searching for resources on the Internet. Reading intensively in the chosen topic area is essential, but the task can prove daunting if they do not approach it in a systematic way. The continuous number of high-profile Internet security breeches reported in the mass media shows that despite an emphasis on security processes that there is still a gap between theory and practice. Not only is there a need to develop better software engineering processes but also theoretical security improvements need to find their way into real systems. Software design patterns are defined as â€Å"descriptions of communicating objects and classes that are customized to solve a general design problem in a particular context†. As software design patterns have proven their value in the development of production software, they are a promising new approach to help in both the theoretical development and practical implementation of better security processes. First, many/most software developers have only a limited knowledge of security processes and patterns are a proven way to improve their understanding. Second, patterns work against â€Å"reinventing-the-wheel† to promote learning best practices from the larger community to save time, effort, and money with easily accessible and validated examples. Third, code can be reused since the same security patterns arise in many different contexts Investigating existing resources in our area of research will generally cover three areas: Exploratory investigations, as part of the development and evaluation of possible topics in an area Investigation is some depth, sufficient to support a formal research and dissertation proposal Complete research that is described in the literature / research section of the dissertation. [from Writing the Doctoral Dissertation, To Author names] 2. Related Research Work Available: Wireless local (WLAN) and wireless personal (WPAN) area networks are being used progressively to implement VoIP services. The main motivation for using these architectures are user mobility, setup flexibility, increasing transmission rate and low costs, despite this convergence depends on the answers of several technical problems Supporting reliable real-time service is one of the major concerns for widely deployment of VoIP in these ireless IPbased networks and security is now receiving the attention of researchers. The problem of offering security to WLAN and WPAN is that security does not come for free and, security and efficiency are conflicting requirements. The introduction of a security mechanism such as the IPSec encryption-engine to overcome these issues impacts directly in the speech quality of established calls and in the channel capacity. Moreover, largely deployed radio technology standards as IEEE 802.11 and Bluetooth used to achieve wireless connectivity have several constraints when delivering real-time traffic, as transmission errors at the channel, introducing delay and loss which with security mechanisms impact can lead to low quality VoIP calls. Although these technologies offer some security mechanisms, they have some flaws which need to be addressed by an additional level of security. In this paper we focus on the IPSec protocol to achieve the data secrecy due to its widely deployment and implementation of many encryption algorithms. During final decades information technology founded on the computer networks take part in an essential role in different areas of human being action. Troubles of huge importance are assigned on them, such as maintenance, communication and mechanization of information processing. The safety level of processed information is able to differ from private and viable to military and state secret. Herewith the destruction of the information secrecy, reliability and accessibility may cause the spoil to its proprietor and contain important unattractive consequences. Hence the trouble of information safety is concerned. Many associations and companies expand safety facilities that need important aids. In additional, the impracticality of creating wholly protected system is a recognized fact – it will always hold faults and  «gaps » in its understanding. To guard computer systems such familiarized mechanisms as classification and verification, methodologies of the delimitation and limit of the access to data and cryptographic techniques are applied. But they hold following drawbacks: †¢ Disclosure from interior users with spiteful purpose; †¢ Complexity in access separation caused by data sources globalization, which cleans away difference between personal and foreign topics of the system; †¢ Diminution of efficiency and communication complexity by reason of methods for access control to the sources, for occasion, in e-commerce; †¢ Effortlessness of passwords description by crating arrangements of simple users relations. Hence classification and audit systems are utilized beside with these methods. between them are interruption. Intrusion Detection Systems (IDS). IDS are generally separated to systems detecting previously identified attacks (mishandling exposure systems) and variance exposure systems registering the life cycle differences of the computer system from its usual (distinctive) action. Besides, IDS are divided to network-based and host-based category by data source. Network-based IDS examine network dataflow, caring its members, almost not moving the output of their work. Network-based systems do not utilize data about progression from divide workstation. A firewall is a mixture of hardware and software used to put into practice a security policy leading the flow of network traffic between two or more networks. In its simplest form, a firewall acts as a safety barrier to control traffic and manage links between internal and external network hosts. The actual means by which this is able varies and ranges from packet sort and proxy service to stateful examination methods. A more difficult firewall may hide the topology of the network it is employed to keep, Firewalls have recognized to be useful in trade with a large number of pressure that create from outer a network. They are becoming ever-present and necessary to the action of the network. The constant growth of the Internet, coupled with the increasing difficulty of attacks, however, is placing further stress and difficulty on firewalls design and management. . [ Subrata Acharya, Jia Wang, Albert Greenberg 2006] Furthermore, the need to deal with large set of varied safety policy and rules impose additional load on firewalls, thus depiction the presentation of the firewall highly serious to enforce the network safety policy. In this context, the defense that a firewall provides only the policies it is configured to execute, but evenly importantly the speed at which it enforces these policy. Under attack or deep load, firewalls can simply become a bottleneck. As the network size, bandwidth, and giving out power of networked hosts carry on increasing, there is a high demand for optimizing firewall operation for improved performance. [ Subrata Acharya, Jia Wang, Albert Greenberg 2006] Multi-dimensional firewall research group of people to focus on mounting various optimizations to make firewalls more resourceful and steady. In spite of significant progress in the design of firewalls, the techniques for firewall optimization remains static and fail to get used to to the always varying dynamics of the network.

This is further compounded by the limited resources of firewalls relation to the increased ability of the network to process and forward traffic at very high speed.
