Rhetorical Analysis Essay The Pound Cake speech by Bill Cosby a well-known actor, comedian, and Philanthropist delivered a controversial speech called The Pound Cake Speech which was presented on May 17, 2004 at the NAACP Gala at Constitution Hall in Washington, DC. In this speech, Cosby was highly critical to members and divisions of the African American community in the United States. He criticized the use of African American dialect, the problems with bad parenting and various other social behaviors. Bill Cosby was effective in his speech because he combined a humorous approach with an emotional and logical appeal. In Bill Cosby’s, Pound Cake Speech, he discusses the African American community’s uncertainty towards parenting. Cosby states that we cannot blame people for the way their children turn out. It can only be the parents fault for letting them develop that way. He strongly believes that parents are the blame for their children’s actions in today’s society. He mentions the Brown vs. Board of education, and how the people fought for their children’s education, only for them to complain about learning. Bill Cosby criticized the African American race in his speech. His reason for this was to make his audience angry. He speaks on the 50% high school dropout rate for blacks and how he believes it is a major problem, also how people call on God for help but they are not doing their parts, the frequency of single mothers, and other social behaviors with today’s youth. However, throughout the whole speech it all lead up to parents not providing good parenting skills. Cosby’s audience was mainly black folks so he knew how to keep their attention by appealing to their emotions. His speech was effective because he combined the pathos and logical appeal, which kept his audience engaged and interested in his speech.

Sex Education in Secondary Schools Essay Background The health and bright future of every adolescent is shadowed by risk of sexually transmitted diseases, unintended pregnancy and even abortion, that will enable them to reach their goals in life. Research shows that one youth is infected with HIV every hour of everyday, while 5% increase in teenage birthrate, 40.5 births per 100 young woman ages 15-19 (Hamilton et.al.2009).This mind numbing fact, is pointed to the aggressiveness, curiosity and misguidance of teens about the issues of sexuality. In a Christian country, like Philippines, these issues are taken with great care and fragility, hence, according to Wagoner (2001), this are public issues that should be treated with rights, respect and responsibility instead of fear, denial and blame. The youth have the right to accurate information, deserving of respect and do have an obligation to act responsibly. Ignorance regarding this is a crucial matter that has an easy remedy: educate the youth and give hope for a more informed tomorrow (Leavitt, 2009). Because like what Wagoner (2001) said, â€Å"By this we could protect their (youth) health and their lives.† Sex education on the other hand, according to Kirby (2002) and Alford (2003), it teaches about abstinence as the best method of avoiding STDs and unintended pregnancy through contraception, it talks about interpersonal and communication skills which help young people explore their own values, goals and options, a prevention program that will affect multiple behavior and achieve positive health impacts. As support to the global call of sex education, Representative Lagman (2008) said that Reproductive Health Bill was formulated by the congress here in the Philippines, that promotes information on access to both natural and modern family planning method, which are medically safe and illegal permissible and assures an enabling environment where women and couples have the freedom and choice on the mode of planning their family while strengthening PopCom in educating the youth. For this reason, the researchers would like to expose the importance and effects of sex education program in the learning of teens and in the preservation of the country as a whole at the same time, assist and guide the youth to be responsible not only in their decision but more importantly to their judgment as to what Villegas (2009) said, â€Å"The only thing that will bring things to order is time.† Statement of the Problem 1. What are the importance of integrating sex education in the learning of teenagers? 2. What are the effects of integrating sex education in the learning and intellectual growth of teens? 3. What would be the impacts of sex education in social, spiritual and sexual development of teens? Statement of the Objectives 1. To instill among the youth the importance of sex education. 2. To show the effects of integrating sex education in the learning and intellectual growth of teens. 3. To reveal the impacts of sex education in social, spiritual and sexual development of teens. Scope and Limitations of the Study The study is only limited on the importance and effects of integrating sex education on the learning of teenagers in the secondary level and it’s feasible contribution towards nation building and global prosperity. It was conducted at La Filipina National High School, La Filipina, Tagum City, from February to March 2010 and was participated by 100 respondents consisting of 20 teachers (five every year level) and 80 students (20 per year level). Significance of the Study For the youth: The main purpose of this study is to provide information about sex education, its importance and effects to the academic performance of teens towards self-preservation and to showcase a wide array of choices to help live a healthy and productive life that would ensure active participation of youth in nation building and global development in the future. For the parents: The significance of the study is to help them to realized their big and vital duty to guide the youth and inculcate among them the values they should bear in mind to lighten their path towards a brighter future. For the teachers: The relevance of this research is to equip them with the right concept in providing not only quality education but also how education be used in fighting ignorance as core cause of deemed tomorrow. For the community: The importance of this research is to give the correct and clear meaning of sex education, as well as, its objectives to awaken the community of its advantage to address the increasing population growth and lessen if may not eradicate sexually transmitted diseases infected and to bring back youth closer to the Almighty creator. Definition of Terms Sex Education -is a program that teaches about abstinence and about using condoms and contraception to avoid STDs and unintended pregnancy, thus develop interpersonal and communication skills. Abstinence -refraining from doing sexual activity before marriage. Sexually Transmitted Disease -or STD is a disease transferred sexually like AIDS, HIV and many more. Morality-is a conduct or attitude judgment from moral standpoint. Unintended Pregnancy -is similar to unwanted pregnancy. Contraception is the process of controlling birth. Reproductive Health Bill -is a bill in the congress that: †¢ Aims to control rapid population growth, unwanted pregnancy and abortion. †¢ Provide the public contraceptives and intensive discussions about issues of sexuality. Chapter II Review of Related Literature The question of weather sex education should be taught in school took along debate up to this very moment inspite with the fact given by the University of the Philippines Population Institute (UPPI) and Demographic Research and Development Foundation, restated by Dr. Singson (2010), 26 percent of our Filipino youth nation wide from 15 to 25 admitted to have a premarital sex experience, and worst is 38 percent of youth are already in live-in arrangement. The Philippine Situationer dated 2009, added that about 1.8m boys and 670,000 girls aging 15-24 have pre-marital relations already, 766 HIV seropositive children and youth, and got pregnant between 18-19 years old that contribute to 400,000 indused abortion annually thus infecting the quality of education gained by youth that unable them to be productive. Wagoner (2001), emphasized sexuality education is not an either/ or proposition, it’s the reality young people needed and deserved. He further stretched, that he will always believe that the better way is to try rights, respect and responsibility to give young people tools and, more they will make safe and responsible decision out of it. Sex education on the other hand, according to Alford (2001), teaches abstinence as the best method to avoid HIV, unintended pregnancy and abortion, it provides value based education, shows variety of choices in the manner of living, accurate information about the reality of sexual issues, teaches proper usage of contraceptive materials to serve as protection, and preaches religious values to give youth opportunity to explore their own. Macken in 2006 also mentioned the programs efficacy in preventing HIV and other STD. Leavitt (2009), determined ignorance regard safe sex is a crucial matter with an easy remedy: educate the youth and give them hope for an informed tomorrow. However, Anderson (1993) President of Probe Ministries International, viewed that the problem is not lack of education, but lack of moral instruction, according to him, young people needed information about sex, but it must be placed in moral context. He further said that we should provide youth with biblical principles and moral leadership in dissecting this issues. In contrary, researchers of Advocates of Youth (2009), stated that sex education clearly shows programs that do not encourage teens to start sexual intercourse, do not increase even the frequency, instead decrease the number of sexual partners which was supported by Kirby (2001) and Alford (2003) and in Mckeon’s research in 2006. That is why Rep. Edcel C. Lagman (2008), author of the RH Bill of the Philippines, wishes to proved that, (1) Information and access to natural and modern family planning (2) Maternal, infant and child health and nutrition (3) Promotion of breast feeding (4) Prevention of abortion and management of post-abortion complications (5) Adolescent and youth health (6) Prevention and management of reproductive tract infections, HIV/AIDS and STDs (7) Elimination of violence against women (8) Counseling on sexuality and sexual and reproductive health (9) Treatment of breast and reproductive tract cancers (10) Male involvement and participation in RH; (11) Prevention and treatment of infertility and (12) RH education for the youth strengthen PopCom, are vital to promote a well oriented community that shall raised the level of public awareness on the urgent need to protect and promote reproductive health and rights. The study of Kohler and et al. (2008) said, that its not harmful to teach teens about birth control in addition to abstinence. Mauluer et al. (2009) also added, that sex education greatly boost the delay if not decreased the intercourse participation rate. Dr. Markham (2009), told that we need to develop prevention programs that address the needs of the students who are not yet sexually active to promote skills and attitude to help them wait until they are older to have sex, we need to provide knowledge of condom and other contraceptive materials to the sexuality active and to give accurate and factual information and services related to STD’s through education. Albert (2010) said, that no one suggests to set guidelines alone will work at all time for all people, that it is important that we will have a large portfolio and effective options, and that is what education could cater. Effects In the academic and intellectual growth. Supposed sex education is effectively implemented. The Millennium Development Goal or MDG #2, which seeks to achieve universal primary education will be attained, for the program will help youth to proceed and finish proper education, thus, creating them employable, said Virola (2009). Senderowitz in 2000 analyzed that, learning about the reproductive health is pout of the larger developmental process as child become adult. He further stated, this developed self-esteem, a sense of hope and goals for the future, and respect for others. Pick de Weiss et al. (1998), said that the study of Institute Mexicano de Investigacion de Familia y Poblacion or (IMIFP) and the New York- based Population Council showed that the course can increase student’s knowledge on how to incorporate sex in the larger context of life. Delano in 2000, Association for Reproductive and Family Health Executive Director, revealed that this assessment could provoke life-building skills like negotiation skills, values classification, refusal skills, decision- making and goal setting. She further emphasized, that this skill will enable youth to cope with the demands and challenges of growing up and self management. Moreover, Mahler (1896) agreed, because according to her this will help youth develop and practice decision- making skills, because sex education is not just about sex, but it facilitates self-esteem and the feeling that you have options and you are in control of things. Nguer in 1999 added, that this education allows youth to be more mature and to be able and face some of life’s problems, it was also supported by Vincent et al. (1987), that the program is focused to improve decision-making skills, interpersonal communication skills, self-esteem and balancing of personal values, which is parallel to what Bailie said in 1995, thus, expressed a strong desire for better education and parents should be part of it. In the study of Cairns (1990), he found out the self-esteem and locus of control were associated with benefits in a single sex school than a mixed- sex environment. Mallam (1993) also revealed that this kind of curriculum showed attitudes toward academic subjects. Impacts on the Social, Sexual and Spiritual development †¢ Social advancements Since social aspect is defined as the relationship and communication into someone or to the community, as a whole. Integrating sex education according to Kirby, restated by Leavitt (2009), that this program can effectively reduced the number of sexual partners. Sex education had been successful in various settings. Sendorovitz (2000), written that the program include peer-based approaches and media activities to reach people thus young people can comfortably and safely explore issues and concerns to practice safer sexual behaviors. Whitaker (2000), reported that its effects were safer behavior and strong ties in the family, school and church. Nguer of 2000 also emphasized, that this also involves respect and responsibility. Since the values of respect for women by men and violence were instill in their minds. Bailie (1995) also added that the opportunity for individual counseling with someone they trust like their parents and friends are also given importance. According to Dohoney (2007) they (youth) learned about how to say no to sex which is a clear result of having a sound judgment. †¢ Sexual improvements Sexual activities are both natural to human and animals yet for human it’s more sacred and treated with respect. Kirby (2007) found that 30 percent of this program lessens sex frequency and 60 percent reduced unprotected sex. Kohler et al. (2008) said that teens who received sex education were 60 percent was likely to report becoming pregnant. According to Grunseit (1997) this activity delayed the inset of sexual activity, reduced the number of sexual partners and decrease unplanned pregnancy and STD rates and a significant reduction in sexual risk-taking. Dohoney (2007) said, that receiving sex education before the first sexual activity has the positive outcome. According to Lagman (2008) this reduces abortion rates by as much as 85 percent that negates the need to legalize abortion. He added that the United Nation and countries with sex education stated, that the youth understand the proper sexual values, early initiation is delayed, multiple sex partners is avoided, spread of STDs is prevented. In conclusion he said this raise the level of public awareness on the urgent need to protect and promote reproductive health and rights. †¢ Spiritual enlightenment When temptation comes let GOD be your guide. 1 Corinthian 10:13 said, â€Å"There hath no temptations taken you but such as in common man: but GOD is faithful, who will not suffer you to be tempted. â€Å"It is clearly stated that with intimate relation with GOD no temptation will ever shake the foundation of our very soul which is faith. According to Leavitt, the mission can only be achieved by offering a personal relationship with Jesus Christ as the best way to live a sexually pure life. In addition, Sanches (2010) said, that if you’re sexually pure because you are educated, you will avoid things that may tempt you to do pre-marital sex, and aborting baby. You won’t feel cheap like used rags, because you believe in God and with it the pursuit for sexually pure is easy. Chapter III Methodology Locale of the Study The location of the study may be classified into two: First, was at La Filipina National High School, La Filipina, Tagum City and the second was at the University of Southeastern Philippines,Tagum-Mabini Campus, Apokon, Tagum City. The former, includes the gathering of data through survey and latter, signifies the interpretation, analysis and making of the entire research study. Procedure After deciding the topic, researches of the anything related to it followed. From these researches, the researchers come up to a survey questionnaire form making it accurate to answer the problems and objectives of the study. The survey was made last March 2, 2010 at La Filipina National High School which was participated by 20 students and 5 teachers every year level summed up to 100 respondents. In every year level, the focus of the survey was only on the first section class having 20 respondents each, composed of 10 boys and 10 girls selected on random order. For the teachers, there were no specific guidelines on choosing who will answer the survey questionnaire. The respondents were chosen for they will be the one who will be affected directly for what so ever the result may be. Interpretation and analysis of the data gathered followed to form the summary, conclusions and recommendations.

Atraumatic Restorative Treatment for Dental Caries

Atraumatic Restorative Treatment for Dental Caries Atraumatic restorative treatment for the management of dental caries: A Review Abstract: Atraumatic restorative treatment is a method of minimal caries intervention that uses only hand instruments. Over the past few years, there has been an increase in the number of studies reporting on various aspects of the Atraumatic Restorative Treatment and it is over three decades ART has been introduced, so this was considered an appropriate time for a systematic review on ART. Objective of this review article was to assess the effectiveness of ART in management of dental caries. All randomized or quasi-randomized control trials on ART were included. Intervention with adhesive restorative material such as GIC with different viscosity was evaluated. Primary outcomes measures such as pain relief, patient discomfort, anxiety and durability of restoration was assessed. Studies showed survival rates ranging from 66% to 76% at 6 year for single surface restorations ART approach provided higher survival percentages for single surface restorations and it causes less pain and dis comfort. Key words: Atraumatic restorative treatment, Survival, Deciduous teeth, Permanent teeth Introduction: Dental caries is one of the most prevalent oral diseases of public health concern. It affects almost all individuals irrespective of age, sex, occupation, religion, castes etc in developed as well as developing countries. It varies greatly among countries, even within a country and from region to region and there are several reasons for this problem like changes in food habits, poverty, lack of facilities especially to underprivileged section of the society, etc. WHO objective of â€Å"Health for All† still remains a dream, particularly in the underprivileged population of the world. Also, there has been a radical change in the methods of treatment of dental disease. We have seen a change in approach of treatment by the dentist, starting with extraction, then conservation of tooth structure and now stress is being laid on preventive dentistry. But the underprivileged population have not benefited from these developments that have brought about improved oral health in the indus trialized world. Realizing the magnitude of this problem, particularly lack of oral health care in below poverty line segment of society, JE Frencken embarked on simplistic approach of removing caries with hand instruments and filling up the ‘cavity’. This approach is termed as Atraumatic Restorative Treatment.[1] ART was first discovered in Tanzania in mid 1980s to suit the needs of the developing countries by JE Frencken Later, in Zimbabwe, the experiment was repeated by his team in larger school population group. WHO endorsed the ART procedure for the underprivileged population on world health day in April 7, 1994.[2] The idea of ART is strongly supported by the modern scientific approach to controlling caries maximal prevention, minimal invasiveness and minimal cavity preparation.[3] Different studies have been investigating the various aspects of ART approach in the past and still continue to increase. Most of the studies have investigated the survival of ART restoration and sealants. As ART approach is being utilized all over the world since more than 25 years, there is a need to carry out a systematic investigation about the survival and effectiveness of ART restorations. So the present systematic review focuses on the effectiveness of ART in management of dental caries in deciduous and permanent teeth. Materials and Methods We attempted to identify all relevant studies. Detailed search strategies were developed for each database to be searched and it was carried out in the Medline, Embase, Hinari, k-hub. All randomized controlled trials or quasi-randomized controlled trials were included. Non-randomized controlled trials were excluded. Studies with Dentate participants, regardless of the age and sex, with a history of dental (coronal) caries who have undergone restorative treatment using either conventional restorative or ART approaches were included. Studies in which evaluators were calibrated and independent, Survival result more than 1 year were included. Interventions were adhesive restorative materials, such as GICs with different viscosities, placed with the ’true’ Atraumatic Restorative Treatment (ART) approach, including Interim therapeutic restoration (ITR) with hand instruments, compared with different restorative materials, such as amalgam, placed with conventional cavity prepar ation methods. Studies on modified ART approaches, Survival results Selection of Studies All records identified by the searches printed off and checked on the basis of title first, then by abstract or keywords or both. Records that obviously irrelevant were discarded and the full text of all remaining records were obtained. The full reports obtained from all the electronic and other methods of searching assessed independently by two review authors to establish whether the studies meet the inclusion criteria or not, using an inclusion criteria form, which previously prepared and pilot tested. Where resolution was not possible, a third review author consulted. If more than one publication of a trial was identified, all publications were reviewed and the paper with the first publication date included as a primary version. All studies meeting the inclusion criteria then underwent data extraction and a quality assessment. Types of Outcome Measures Primary Outcome Measure Pain relief, i.e. freedom from symptoms of pain and sensitivity as reported and experienced by the patient. Patient discomfort during the procedure measured by physiological measurement or behavioral observation. Patient’s anxiety and stress after treatment. Durability of restoration survival time of restoration (in months) from the time of placement. Secondary outcome measures Defects of restorative materials such as wear, fracture and staining (color changes) of restoration. Restoration failure, e.g. replaced restorations. Marginal integrity of restoration. Secondary caries. Results Pain, Anxiety and Discomfort: Five studies were reported on pain out of which three studies suggested that ART was found to be less painful.[4,5,6] In a study conducted by Rahimtoola S et al[7] pain was reported when ART technique was used but was significantly less than the conventional restorative technique. While in one study there was no significant difference in the pain levels of children treated using conventional restorative treatment, atraumatic restorative treatment or ultraconservative treatment but it was observed that when conventional restorative treatment was used, more children neededlocal anesthesia.[8] One study showed that the levels of dental anxiety were less in patients treated with ART as compared to conventional restorative treatment.[9]The studies from Topaloglu et al[10] and de Menezes Abreu et al[11] reported no difference in the levels of dental anxiety. ART technique has a potential to cause less discomfort to the patient and to less invasive to the dental tissue than conventional approach. The patient’s acceptance of ART was verified by Mickenautsch et al[12] who observed that both children and adults receiving ART restorations responded positively to the treatment. Study conducted by Schriks MC[13] and Van Amerongen WE[14] stated that children treated according to the ART approach using hand instruments alone experience less discomfort than those treated using rotary instrument. Similar findings were reported by ECM Lo CJ Holmgren also.[5] A summary of these studies outcomes is presented in Table1. TABLE 1: Overview of studies having assessed dental pain, anxiety and discomfort between the ART and the traditional treatment approach Comparison Age Operator background Variable measured Conclusion ART vs rotary Instruments[7] 6–16 years old Dentists Pain: -Questions: Did you feel any pain during treatment?

Lo ECM[16] Suggested that cumulative survival rates of the large restoration were lower, being 77% and 46% after 3 and 6 year respectively. There were no statistically significant differences in cumulative survival percentages of the evaluated ART restorations between single and multiple-surface restorations at 1-year (p=0.137) and 2-year (p=0.377) evaluations. But at the 10-year evaluation, the survival rate for single-surface restorations (65.2%) was 2.1 times higher than that for the multiple surface restorations (30.6%). This difference was statistically significant (p=0.009).[17] Secondary Outcome Measures: Defects of restorative materials wear and fracture of restoration: Studies conducted by Lo ECM[16] and Frencken JE[18] showed that most of the restoration were in good condition and had only minor defects and wear which did not warrant further treatment. Secondary caries Increment of secondary caries was found to be maximum in a study conducted by Zanata RL[17] while other studies showed no statically significant difference.[18,19] Operator effect. Frencken JE [18] et al observed an operator effect for single surface ART restorations. It was observed in one study that experienced operators place better ART restoration than inexperienced operators.[15] Marginal Integrity of Restoration: In a study the restorations that were evaluated with the USPHS criteria at the 5-year examination, unacceptable marginal integrity, either a crevice extending to the enamel–dentine junction or the restoration being fractured was found in 9% of the small and 21% of the large restorations.[18] While in another study, 63.6% of the ART restorations were assessed as ‘good’, 15% as having a ‘slight marginal defect’ at 3years.[19] Restoration Failure Failure occurred in 24% of the small restorations and 41% of the large restorations. The large restorations had a higher relative risk of failure, 5.87, compared with the small restorations.[16] Failures were related to unacceptable marginal defects and total loss of restoration. Frencken JE [18] reported failure of total 28 ART restorations placed in 25 students during the 3 year period. While same author in another study reported 106 ART restoration failures from total of 487 ART single surface posterior restorations.[15] Discussion: The ART approach seems to be an economic and effective method for improving the oral health not only of people in developing but also of those in industrialized countries (Frencken and Holmgren 2004).[1] It may be considered as a safe and conservative alternative for conventional restorative dental treatment, particularly for Class I (occlusal) dental cavities. Pr imary outcome measures: Pain, Discomfort and Anxiety: The originators of the ART approach noticed that the technique had a potential to cause less discomfort to the patient and to be less invasive to the dental tissues than the conventional approach. The patients acceptance of ART was verified by Mickenautsch and Rudolph[12], who observed that both children and adults receiving ART restorations responded very positively to the treatment. Dentists also seemed to approve the â€Å"new† approach. Among the main reasons given were those related to the patients comfort: the reduced use of local anesthetic and absence of the noisy drill and suction.[20] Some suggested that ART as found to be less painful and cause less dental anxiety. The reasons could be contributed to the operator’s level of specialization and /or skills in handling anxious children. The studies from Topaloglu et al [10] and de Menezes Abreu et al [4,11] in which no difference in levels of dental anxiety and dental pain were observed, were performed by pediatric dentists. In the studies that favored ART [7,8,13] all operators, but the one from de Menezes Abreu et al, [8] were non-pediatric dentists (general practitioners, dental therapists or dental students). However, the latter study had included children younger than 6 years, and all those given the conventional treatment received local anesthesia and the restorations were performed under rubber dam isolation. It is not unrealistic to argue that age and the use of the needle and that of rubber dam might have influenced childrens perception of pain. In light of all these aspects, it can be hypothesized th at the behavior management provided by a pediatric dentist may overcome much of the discomfort that a child can feel independent of the restorative treatment approach. Durability of Restoration: The survival percentages of single surface non occlusal posterior ART restoration were significantly higher than for comparable amalgam restoration 4.4, 5.3 and 6.3 years. Although it is known that non occlusal glass ionomer restoration survive long but significant lower survival results for non occlusal amalgam than for comparable ART glass ionomer restorations were observed.[15] The cumulative survival rate of ART single surface restoration remained high throughout the study 92.7% (SE 3.0%) over 2 years and65.2%(SE 7.3%) up to 10 years. These rates are in the line with the results of other investigations, which reported survival rates ranging from 66% to 76% at 6 year for single surface restorations. The cumulative success of 65.2% observed in this study could be considered even better due to the longer period of clinical service. The survival rates of multiple surface restorations (class II) decreased significantly from 2 to 10 years. After 2 years, the survival rates between single and multiple surface restorations were similar. These results are consistent with those of Cefaly and Farag which observed similar survival rates for class 1 and class II restoration after 1 and 5 years, respectively. However, a statistical difference was apparent over the 10 year evaluation period (65.2Ãâ€"30.6% success rates for single and multiple surface restorations, respe ctively).[17] Secondary outcome measures: Defects of restorative material such as Wear, Fracture and Staining of Restoration: The annual wear rate of the high strength glass–ionomer material used in their study was rather stable at around 20-25 m after the first year and this did not increase much with time or size of the restoration. This rate is very satisfactory and may help to alleviate some of the concerns of earlier reviews on ART. The use of an adhesive material in ART restorations also makes repair of restorations with gross defects and wear possible and total replacement may not be necessary.[15] Reasons for minor defects and wear can be explained by the fact that firm finger pressure was applied over the restorative material to ensure good penetration of glass ionomer into the pits and fissures, as recently demonstrated.[18] Secondary caries: It has been shown that caries left in occlusal enamel lesions had either not progressed at all or only progressed slightly under clinically ‘intact’ as well as ‘sometimes intact’ sealants after 3 years. In contrast, caries had progressed under sealants that were ‘never intact’.[18] No ART restoration failed because of carious lesion development only. Restorations failed because of a combination of dentine carious lesions and mechanical defects.[17] This pattern of failure was also observed by Frencken et al[15] but contrasts with the study of Prakki et al[21] which observed no caries even in those teeth whose ART restorations were missing. Operator effect: An operator effect has been cited in a number of ART studies.[18,22,23] Although all operators (dentists and dental therapists) in the studies referred to above had followed a training course on ART, the operator effect seems to indicate that in order to perform quality ART restorations, the operating dental personnel requires skill, diligence and comprehension. An ART training course of a couple of days may be too short for some qualified dentists and dental therapists.[15] The operators’ greater experience in applying ART and the use of a high-viscous glass ionomer in the study may explain the higher results.[18] Failure of Restoration: The finding that failures of ART restorations placed in the same child were correlated suggests that some factors related to the individual subjects such as diet, occlusion, and caries risk may influence restoration survival.[16] The predominant reasons for ART restorations to fail were unacceptable defects at the margin and re restoration.[15] Almost half of the failures were related both to the physical characteristics of the glass ionomer used and to the operators’ handling of the material. Few failures were due to excessive wear. The other half of the failures were considered to be operator related. The exact reasons for the unacceptable marginal defects were unknown. However, it can be speculated that improper mixing of glass ionomer, providing a mixture that was either too dry or too wet, was one of the reasons. Another reason could be the difficulty in inserting the material into the depths of deep and small preparations. Subsurface voids produced during insertion may have resulted in later fracture of the surface layer under pressure.[18] Compared to conventional treatment approaches, ART is still very young. Despite this, much progress has been made in researching various aspects of the ART approach. More experience in the actual technique of cleaning carious cavities with hand instruments has been gained and newer, physically stronger glass ionomers have been marketed as a result of its existence. These developments have most probably led to the higher survival results of ART restorations in permanent teeth in the more recent compared to the early studies. Conclusion: ART technique has proved to be less painful and causes less discomfort to the patients with high survival rate in both in primary and permanent teeth. This technique has the potential to make oral health care more available to a larger part of the world’s population than before. The greater part of the world’s population has no access to restorative dental care. ART should be taken seriously by the dental profession and educational courses should be organized before the approach is used in the clinic.

Huckleberry Finn Learns He Must Grow Up Fast If He Wants to Survive Life   Ã‚  Ã‚  Ã‚  Ã‚  Huckleberry Finn, the main character, learns he must grow up fast if he wants to survive life. Huck Finn has a drunkard as a father, a hogshead as a home, and a mother (dead ) of which he never knew. He is a congenital liar, a thief, and someone who has no respect for the rules of society. He will use every technicality to get off with doing something completely wrong, but is ok by him. Huck is not all evil as one would think by this introduction. He in fact believes in personal freedom, something which he never really has had.   Ã‚  Ã‚  Ã‚  Ã‚  Jim, a supporting character, also has to deal with many problems of society. The greatest one in fact is, the fact that he is a slave. Jim is a very modest person, he will sacrifice anything to help his fellow man. Huck sees this and begins to think of Jim as a human being also, and will â€Å"go to hell † for Jim. Although Jim is a slave, he does not think of people based on their skin color, but in fact believes that everyone is equal regardless of skin, and even age. One may ever say that Jim is Huck's true father.   Ã‚  Ã‚  Ã‚  Ã‚  Both Jim and Huck have experienced life at a tedious level. They have their highs and lows, but mainly life is not all it is cracked up to be. For Huck, he must experience having a horrendous father who beats Huck to a pulp any time he is sober. And for Jim, the fact that his family is not considered human by society but rather chattel that can be bought, sold or even traded at the slightest whim. Together Huck and Jim must work together to escape the society which has allowed them to live the vile life they had, and move to a place where society will let them start a brand new life. When Pap , was not around, Huck felt better about himself. He enjoyed life a little more, did not have to worry about coming home on time, only to get beat up by his own pap. He kept me with him all the time, and I never got a chance to run off. We lived in that old cabin, and he always locked the door and put the key under his head nights. He had a gun which he had stole, I reckon, and we fished and hunter, and that was what we lived on

Larnyx Cancer :: essays research papers

Cancer Information: Larynx Cancer  Ã‚  Ã‚  Ã‚  Ã‚     Ã‚  Ã‚  Ã‚  Ã‚  Larynx cancer is a cancer that effects the larynx, or voice box, in people; it can also be called laryngeal cancer. The cancer occurs most frequently in people over the age of fifty-four and in black males. The larynx is approximately two inches long and is located below the nose passage way and above the trachea. Tumors can develop anywhere in the three parts of the larynx, the glottis, supraglottis, and subglottis. When the cancer spreads to other parts of the body it is called metastatic cancer.   Ã‚  Ã‚  Ã‚  Ã‚  Symptoms for this type of cancer depend mainly on the size and location of the tumor. Most cases of larynx cancer occurs in the glottis area, or vocal cord section. When a tumor develops in this area it is usually painless, but almost always results in hoarseness and a change in the person’s voice. If the tumor occurs in the supraglottis, or the section above the vocal cords, it may cause a lump in the throat, sore throat, or earaches. When the tumor develops in the area where the larynx and trachea join, subglottis, the person experiences trouble in breathing, very noisy breathing. Constant coughing or a feeling of a lump that doesn’t go away are also signs of larynx cancer. Tumor development in the subglottis is very unusual and rare. As a tumor grows it may cause pain, weight loss, bad breath, frequent choking on food, and hard swallowing. Only qualified doctors are able to tell if any of the signs are really symptoms of the cancer.   Ã‚  Ã‚  Ã‚  Ã‚  A person with larynx cancer can be treated according to the person’s age, general health, and preferences. The size of the tumor, location of the tumor, and whether the cancer has spread or not also plays a major role in determining the type of treatment. Treatment can be done by local therapy or systemic therapy. In local therapy there is a choice of radiation therapy, surgery, or a combination of both. The only choice in systemic therapy is chemotherapy. When radiation therapy is used high-energy rays damage the cancerous cells and stops them from growing larger. A patient treated by radiation has a better chance of keeping his or her voice after the treatment. Treatment usually last for five days per week for five to six weeks. Surgery is used when the tumor continues to grow even after radiation has been applied.

The Discovery Of Economy Essay -- essays research papers

It is a pristine tradition that much matters to a nation, when it comes to issues irrelevant to human development. Speaking in terms of reality, the economic boom of a nation is what human development all about. Now let us profoundly analyze what exactly is the economic boom of a nation. As we begin our analysis, it is highly important for the reader to be enlightened with the fact that it is necessary to think the right way if he has to understand this immensely valuable message. The reader will have to discredit all economic and political concepts and thoughts in considering the planet earth as a single nation and its people as just its citizens with no individual nationalities. Thinking this way alone can make this message more comprehending. Today everyone knows the fact that the world has, due to the advancement in human transportation and communication technology, virtually shrunk to a small global village. Much gossip is evident in the electronic media on the virtual currencies in circulation on the Internet. So it is clearly evident that it solely depends on the way we think, for which each single nation is a proof. Let us consider for example that if fifty states of the USA are divided into fifty nations, then fifty different currencies come into existence with different living standards in each nation. Formalities and barriers will have to be braved by the people as for the flow of people, goods and services from one state to the other. Bureaucratic interference will always remain whenever there is an exchange of business, trade or travel between any two nations from among the fifty. On the contrary if the fifty are again merged into a union of the USA, then there is no need for working out on policies, sovereignty , constitutional amendments, economy, GDP's, GNP's, exports and imports of the fifty states with each state as a separate nation. Similarly let us apply the concept to all the so-called countries of this world considering them to be a single nation at least in economic terms, if not socio-politically. Let us keep in mind the fact that the all the nations of the world, just for the purpose of serving their selfish national ends, have been committing blunders on the economy of this world. Because of the absurd and weird reason that we are socio-politically, culturally, lingually and in many other aspects different from each other, we h... ...0. A coke can in India may be Rs. 15 or more and if it is being bought by 10 million people per day then at Rs. 1 or 2, certainly 200 million people at least will buy it every day. The electricity and medical services must be free of cost and should be considered as a mandatory requirement for all the people of earth’s expanse. Let any form of government rule the world union’s so-called nations. Let us pave way to the economic development of the masses of this world, being irrespective of whether a nation is ruled by a military regime or democracy or any other form of Government. Let the penal code be the strictest of all human times. Let us value human or victim’s rights more than criminals’ rights. For some time the world will have to abandon all sporting events, and unnecessary re-search in space, cloning etc. and plan in a smart manner the smooth and speedy union of all nations of this world into a single nation. Let us make nations a single market for all businessmen on Earth’s land, and earth’s Union a home for the entire community of this world with a healthy, wealthy and hygienic environment, which is economically sustainable, viable, affordable, prosperous and livable.

Critical Analysis for Composed Upon Westminster Bridge

William Wordsworth growing up spending most of this time alone and almost always around nature, typically writes of how we are affecting nature. However in the poem Composed upon Westminster Bridge we see a different side of Wordsworth were he describes a city so still and peaceful the beauty is hard to pass unnoticed. Throughout Composed upon Westminster Bridge Wordsworth uses imagery, figures of speech and tone. This poem we see a new side to Wordsworth’s writing, Wordsworth uses imagery as a way to make us see and feel what he is as he looks over Westminster Bridge. He uses visual imagery to make us picture the beauty he is it witnessing. â€Å"All bright and glittering in the smokeless air†, he sees that even the things we never thought to have beauty can prove to be some of the most beautiful things. â€Å"Never did a sun more beautiful steep†, nature has a way of taking the most simple things and making them look of something of great beauty. In line eleven Wordsworth uses the sense of inter emotions. Saying â€Å"Ne’re saw I, never felt a calm so deep†, what he saw that morning made him feel so at ease. It is as though he is surprised at how the simplest things from nature can sway our emotions. Wordsworth uses personification in several places in the poem, in reference to the city, sun, river, and houses. He creates the impression that nature is a living being with a soul. In line twelve, â€Å"the river glideth at his own sweet will†, is saying nature has a way of taking its own path and journey when it’s not corrupted by humans. The beauty of such simple things can be seen better when all is still. With the tranquility we can view nature’s natural beauty, like said in line thirteen, â€Å"Dear God! The very houses seem asleep†. Nature has a way of dressing the city with beauty that we cannot always imagine, â€Å"this city now doth, like a garment†, Wordsworth is using a simile to compare the morning beauty to clothing. The manner in which Composed upon Westminster Bridge is written shows a few different tones. Such as, in the first three lines he is showing admiration for the beautiful sight he sees. It’s as though he’s praising the simplicity of the beauty. Also shown in line nine, â€Å"never did the sun more beautifully steep†, is a tone of praise and awe at just how beautiful a sight it was. The last four lines Wordsworth writes give the tone of peace. How the city was so calm that for those moments it was peaceful. The way Wordsworth uses imagery, figures of speech and tone in the writing of Composed upon Westminster Bridge is how he can get other to feel as if they were there that morning to see and feel what he did. This poem shows that there is beauty in everything, but that to sometimes see this beauty we must look harder to find it.
