Lesch-Nyhan syndrome is a disease caused by metabolic disorder of purine. General muscle stiffness and hyposomia are shown from infancy and symptoms can include involuntary or irregular movements of arms and legs, mental retardation, and compulsive self-mutilating behaviors. Self-mutilating behaviors begin at approximately the first year or sometimes at late teens. The patients bite their lips, especially lower lip, tongue, buccal mucosa, hands and fingers. Tongue and lips can be injured or mutilated in severe cases. As the patient gets older, self-mutilating behaviors become more serious and extensive and secondary infection of injured areas is possible. Periodic soft tissue damage due to self-mutilating may evolve to cancer. Medical treatment, appliance treatment, extraction of tooth and surgical operation was attempted to control self-mutilaing behaviors. We hereby report the case of child Lesch-Nyhan syndrome patient who has self-inflicted labial damage as chief complaint. When patient was treated with conservate therapy, such as removable or fixed appliance, the frequency of labial damage could be subdued and yielded favorable results.

The purpose of this study was to examine the influential relationship between the type of dental treatment and the dental fear of teens in a bid to seek ways of relieving adolescents of dental anxiety and fear. The subjects were teenaged students in South Gyeongsang Province. After a survey was conducted for eight days from December 2 to 9, 2009, the answer sheets from 420 students were analyzed. The findings of the study were as follows: When a correlation analysis was employed to look for connections between dental treatment experiences and dental fear, the components of dental treatment experiences had a significant correlation to those of dental fear. As a result of making a regression analysis, overall dental fear was under the significant influence of prosthodontic treatment experiences, and avoidance of dentistry was significantly affected by conservative treatment experiences. Oral and maxillofacial treatment experiences had a significant impact on physiologic response, and dental stimulus was significantly affected by prosthodontic treatment experiences. Therefore dental institutions should direct their efforts into the development of manuals geared toward different types of treatment and different patients in order for adolescents to receive dental treatment without any anxiety or fear, to get a regular dental checkup, to receive more preventive treatment, to promote their oral health and ultimately to lead a healthy life.

Injury has recently become a major world-wide health problem. Injury related deaths occur in many actively working young people and produce major social and economical losses. However health related specialists do not recognize the importance of injury and there have not been many studies related to this problem. This research studied the trends of injury related research in Korea, mortality rate and prevalence rate, socio-economical losses and control in Korea and out of the country, based on literature from Korea and without such as statistical yearly reports on causes of deaths and OECD health reports, as well as WHO web sites. Studies in Korea about injury were very few, with 9 in the 1960's, 5 in the 1980's, 4 in the 1990's and 5 in 2000's. Mortality rate of injury was higher in Korea than in England, USA or Japan, especially in car accidents, suicide and falls. In Korea, the yearly trends in mortality rates were highest in car accidents but those rates are falling, suicide is steadily rising, with highest rate in 2003. Falls is in second rank with no change in rates. In 2003, the ten causes of death in Korea were suicide in 5th rank, transport accidents in 7th rank, and falls in 10th rank. Considering age groups, in the teens, transport accidents were 1st rank, in the 20's and 30's, suicide was 1st rank, and although there were some differences, falls, drowning, assault, fire were in the top 10. Prevalence rates of injury could not be known, but in 2001, according to the National Health and Nutrition Survey, lifelong injury was 10%, and yearly major injury was 1.3%, major injury for two weeks was 0.1%, and minor injury was 10%. In other foreign countries, injury has become to be recognized as a major health related problem, and much programs are being set up to reduce injury related deaths and injuries. WHO is putting much effort in prevention of violence and transport accidents, and in the USA, Canada and Europe, there are injury surveillance systems. Recently, as suicide is increasing rapidly and providing much problems, each country are managing suicide prevention programs. In Korea, Ministry of Construction and Transportation is managing and guiding the policies for prevention of transport accidents. In September of 2004, the Ministry of Health and Welfare has set up a 5 year plan of suicide prevention.

Cabbage (Baechu) Kimchi in its truncated form was placed in four different packing materials, Ny/PE/LLDP, OPP/AL/PE, PP and PET, and quality changes were observed during storage. Changes in pH and total acidity showed an x-shaped cross-curve as pH decreased and total acidity increased during storage. PP tray showed the slowest change at $5^{\circ}C$ with time. The pH was initially 6.25, but decreased to 4.12~4.16 at 20 days, and total acidity showed a 4 to 4.8-fold increase after 20 days of storage compared to the initial value. During storage at $5^{\circ}C$, total bacterial count and lactic acid bacterial count rapidly increased after 4 days. The total bacterial quantity decreased after a period of time and there were differences according to packaging material; OPP/AL/PE packaging showed the most dramatic decrease. Change in microbial count mostly followed a similar pattern to that of total acidity for all packaging materials. Changes in the color of Kimchi liquid, when examined by color index in $L{\cdot}b$/a form, rapidly decreased over time, similar to pH. Small Ny/PE/PP and OPP/AL/PE packages of Kimchi were examined for changes in free volume inside the packaging. After 13 days of storage at $5^{\circ}C$, the volume was 243 mL, but storage at $20^{\circ}C$ resulted in a volume of 372 mL, a more than 1.5-fold increase in free volume. There were changes in the quality characteristics of small package Kimchi according to storage temperature and packaging material, and large changes in pH, total acidity, and microbial count were evident upon storage at $5^{\circ}C$ for 8 days, which was the optimum palatability period. Mostly, PP treatment showed the slowest quality changes upon storage at $5^{\circ}C$. However, due to small package Kimchi's fast consumption system, the appropriate choice of packaging material must consider the product's turnover ratio. Further, the varieties of small package Kimchi should be diversified according to different consumer preferences by offering Kimchi with different maturity levels. Further, since the leading consumer base ranges in age from the teens to thirties, the development of various products targeting such consumers is necessary.

In this study, we examined the use of cosmetics among adolescents in our country and their purchasing behavior, as the use of cosmetics has increasingly been prevailing in the younger generation. The aims of this study were to investigate the state of the youth cosmetics market, to grasp the needs of youth and ultimately to suggest the right directions for the youth cosmetics market. The subjects in this study were 1,092 boys and girls from 10 selected secondary schools in Seoul. After a survey was conducted, the answer sheets from 1,074 respondents were gathered, and the collected data were analyzed by the statistical package (SPSS WIN 18.0). The vast majority of the teens participated in the survey were answered to use basic cosmetics daily, and there was a gradual increase in the frequency that they used color cosmetics. They started to use cosmetics earlier in ages than the older generations. Most of them were in trouble due to acne, and the most dominant way to get rid of their skin troubles was by using cosmetics. The most common place at which they purchased cosmetics were brand shops, and they gave priority to the function of the products when they bought cosmetics. The adolescents were still told by their schools to abstain from using cosmetics, and that was the case for social climate as well. Yet they definitely wanted to be allowed to use cosmetics.

This study examined whether any differences can be found in desirable character traits and creative personality characteristics depending on the appearance management behaviors of male and female adolescents in Gwangju, South Korea. It was conducted by administering a self-report survey to 544 male and female middle school students. The collected survey data were analyzed by Means, Cronbach's ${\alpha}$, Factor analysis, One-way ANOVA, and Duncan-test using the SPSS/PC WIN 19.0 statistical program. The results were as follows: According to the results of the survey, total coordination seeking in appearance management behavior is very important to teens and is deeply related to desirable character traits and creative personality characteristics. Desirable character traits show positive results for basic living habits, filial piety, respect and affection. Creative personality characteristics show positive results for curiosity, open thinking, risk taking, assignment completion and esthetic appreciation. Considering these findings, there is a need for supplementary content on total coordination seeking behavior in home economics courses. Positive effects in terms of desirable character traits and creative personality characteristics can be expected through after class activities involving clothing habits or searching for a path in life and given the depth of education related to total coordination through a free semester system.

Generation Z(Gen Z), which is referred to people in their late teens to early 20s, becomes one of new major consumer groups in the society. More than 80 percent Gen Z use YouTube content as a main information channel. In this study, we investigate what kind of factors make Gen Z immersed when watching YouTube content. In the background study, we examined immersion and set the cognitive conditions of immersion as reality, fascination, control, and driving as a framework for analysis of case study. In the case study, we analyzed the most popular YouTube channels of each category among the Gen Z with the established framework and then identified 3 main factors: reality, 5 senses, and unpretentiousness and 8 characteristics of them. By conducting survey with Gen Z, we wanted to verify the validity of the characteristics and find out the difference among categories. Subjects answered on a five-point scale how the characteristics of each immersion factor corresponded to their favorite channels. As a result, seven characteristics: 1) familiarity of background, 2) reality of acting, 3)familiarity of material, 4)YouTubers' appearance and 5) voice, 6)multi-sensory, and 7)YouTuber's ability to resemble viewers influenced more than 50% of users' immersion. Although there was no significant difference among categories, the familiarity of the material and the five senses stimulus (YouTube's appearance, voice, audiovisual and surrogate taste) were the most important factors in the entertainment category.

The concentrations in women's hair of essential and toxic elements such as Zn, Ni, Fe, Mn, Cu, Cr, Pb and Cd in residential and factory areas in Pusan were determined, and all the elements were detected from all the samples. It was apparent that employees working in factory areas in Pusan were exposed directly to the essential and toxic heavy matals. This is based on the fact that average concentrations of Ni, Fe, Mn, Cu, Cr, Pb, and Cd in hair samples from women aged 10 to 29 in factory area, who were considered to be main members among women employees, were much higher than those of residential areas. That is, the highest concentrations found in the hair samples taken from women 10 to 29 years old living in factory areas were 110 times higher in Cr (in the women in their 20's), 92 times higher in Pb (in the women in their teens) and 23 times higher in Cd (in the women in their 20's) than those living in residential areas. Furthermore, it was suggested that the heavy metals may be accumulated gradually in human bodies as humans get older, based on the fact that the concentrations of Cr, Pb, and Cd in women living in residential areas were higher in older age groups, although the average contents of these elements in residents from residential areas were similar with those of several foreign countries.

Oral health projects that cater to the disabled should be more prevailing in order to ensure the maintenance and successful promotion of the oral health of disabled people. 70 public dental clinics that conducted oral health projects geared toward the disabled were examined to get a precise grip on their oral health projects. The findings of the study were as follows: 1. 31 out of 70 public dental clinics investigated(44.3%) were equipped with two or more dental hygienists who were professional human resources in charge of the oral health projects for the disabled. As for the age and disability type of the beneficiaries of the oral health projects, adolescents(74.3%) and people with mental retardation(87.1%) benefited most from the oral health projects. Concerning the most common implementation frequency of the projects, the projects were carried out once to three times a week(62.9%). 2. The most dominant oral disease treatment provided to disabled people was amalgam treatment and resin treatment(68.6%), which were the early dental caries treatment. The most common preventive treatment that was offered to improve their oral health was oral prophylaxis(82.9%). As for reform measures for the oral health projects, education of personnels in charge of the projects and their specialization(58.6%) were most emphasized. 3. Regarding factors related to the preventive oral health projects for the disabled, the implementation of oral prophylaxis and toothbrushing education was linked to the age of the beneficiaries. More oral prophylaxis was offered to teens, and more toothbrushing education was provided to preschoolers and adolescents. The age of the beneficiaries and the number of dental hygienists responsible for the projects had something to do with the application of fluorides. 4. Concerning the relationship of the preventive oral health projects for the disabled to the number of dental hygienists, one of the personnels in charge of the projects, the application of fluorides( 54.4%) and pit & fissure sealing(56.8%) were more prevalent when there were two or more dental hygienists. There was a statistically significant disparity in that regard(p<0.05). The above-mentioned findings illustrated that in order to boost the oral health of the disabled, dental hygienists who are responsible for the oral health projects for the disabled should put ceaseless efforts into fostering their professional knowledge and ability and offering quality service to disabled patients. Every public dental clinic should be equipped with plenty of professional personnels to enlarge the scope of treatment and ensure the efficiency of treatment and the preventive projects.
