Objective: This study focused on the longitudinal associations between self-esteem and peer relationships in Korean adolescents while considering gender and timing-early and late adolescence-differences. Methods: The study made use of data from the Korean Children and Youth Panel Survey. Three waves of data collected from 2,351 adolescents were analyzed by means of autoregressive cross-lagged modeling. Results: The results indicated that self-esteem predicted subsequent changes in peer relationship but not vice versa. Further, the results that longitudinal associations between self-esteem and peer relationships differed between male and female adolescents and between early and late adolescence. Conclusion: The findings revaluated the longitudinal relationship between self-esteem and peer relationships. Both gender and timing should be considered when planning interventions related issues about self-esteem and peer relationships in adolescence.

The purposes of this research were to segment consumer groups according to sportswear benefits sought and to find the differences among the groups in regard to domestic vs imported brand attitudes, internet vs department store attitudes, and sportswear purchasing behavior. The subjects used for the research were 773 male and female consumers who were residents in Seoul. The data were analyzed by factor analysis, cluster analysis, ANOVA, and Duncan test. The results showed that there were four sportswear benefit segments: figure compensation/ ostentation, individuality, comfort/function, and youth-oriented groups. Statistical analyses showed that the four sportswear benefit segments were different in regard to imported brand attitudes, department store attitudes, and sportswear purchasing behavior. For example, figure compensation/ ostentation segment had more positive attitude toward imported brands and department stores, considered design and advertisement important as sportswear selection criteria, and had a highest expenditure on sportswear purchase. The implications of the research were discussed.

The purposes of this phenomenological study were to investigate the sexual experiences of juvenile delinquents, and to understand how ecological systems affected their sexual activities. The participants were 13 adolescents on probation and 12 adolescents from juvenile correctional facilities or prisons. They explained their meanings of sex, their sexual behaviors, and their coping strategies for sexual problems. Participants conceptualized sex as physical intercourse, while excluding the emotional aspects of sex. They accepted adults' sexist attitudes toward male and female sexual behaviors, and followed adults' commercialization of sex. In contrast to their routinizing sexual behaviors, they had neither enough knowledge of sex nor effective strategies to solve sexual problems. The sexual activities of juvenile delinquents were influenced by their peer groups and sexual messages from media and internet, rather than by their tamely and school. The holistic view of the study highlights the importance of interactions between individuals and the ecological systems when interpreting the sexual experiences of juvenile delinquents.

Purpose: The purpose of this study was to identify the influence of early menarche on sexual experience among high school girls in South Korea. Methods: The study sample was comprised of 16,286 high school girls. Using statistics from the 11th (2015) Korea Youth Risk Behavior Web-based Survey, hierarchical logistic regression analysis was conducted. Results: Among the girls, 5.8% reported early menarche. Early menarche was associated with sexual experience (Odds Ratio (OR), 5.27; 95% Confidence Interval (CI), 4.11-6.77). Controlled for sociodemographic, emotional and health behavior characteristics, early menarche was associated with sexual experience (OR, 3.98; 95% CI, 3.04-5.21). Conclusion: The results indicate that early menarche predicts an increase in sexual experience among female adolescents. Therefore, health education programs and health policy for interventions to improve sexual health are required for girls who are expected to experience early menarche.

Image of Modern Art & Fashion are created on the whole in daily life. Image itself is not simple. There is no more distinction between content & form through mutual crossing for intellectual thinking. Specially, image of reproduction circumstance too many mixtual and compromise (collage) are continued to occur. They could pursuit to change their image through the more increase of impulse, exception and popular experience. In this thesis, I studied about image of Modern fashion & Art. In the modern art, visual image showed as anti-beauty and combination of cultural system. It has shown in the theory of Fred Davis and through fashion brand advertising image as follows; Youth vs maturity (ageless image), male s female and androgynous vs unisexuality (genderless image), colligation vs monopoly (street mode image). As a results, the modern trend image are showing the value of the ambivalence. It can be said that he anti-beauty which are occasionally showed in ambivalence has shown a tendency toward another tradition (feminity) through giving an impulse and paradox.

Enhancing labor market flexibility is currently posted as one of the major economic policy objectives in Korea. However, the labor market effects of specific policies to achieve it have not been sufficiently investigated. This paper takes up the issue of employment protection deregulation and surveys and empirically analyzes its policy effects. Academic researches generally confirm that deregulation tends to promote labor turnover and employment of the disadvantaged groups such as the youth and female by raising the overall efficiency of the economy, but its effects on unemployment is not clear. In the Korean labor market, both job creation and destruction, and labor mobility have increased after the economic crisis of 1998, but they can not be seen as deregulation effects as the changes are confined to the temporary and daily employment whose labor markets are least regulated whereas the regular employment market remains virtally unchanged. Such results suggest that labor market deregulation need to be pursued consistently as a policy goal since the labor demand condition shift and the need for expanding regular employment necessitates it, for which detailed policy agenda for removing market inefficiencies should be carefully arranged.

This study was performed to provide normative isokinetic strength of knee muscles of middle school non-athletic and athletic populations for rehabilitation and pre-season screening for injury prevention. Seven non-athletic subjects and 8 hockey players participated in this investigation. Each subject was tested at speeds of $60^{\circ}/sec$, $180^{\circ}/sec$, and $300^{\circ}/sec$. The free weight of lower leg was measured at speed of $60^{\circ}/sec$ to take gravity effect Into consideration when peak torque of knee muscles occurred. The results showed that the relative peak torque production of knee flexors did not change but the relative peak torque of knee extensors decreased significantly. Mamstring/quadriceps ratios increased mainly due to significant decreases in knee extensors torque production. No significant differences were found between groups. The hamstring/quadriceps ratios for both groups were significantly lower when the gravity effect was not eliminated.

Objectives: The purpose of the study was to investigate the effect of gender in the association between the oral symptoms experience and health behavior. Methods: The subjects were 54,219 adolescents selected from the web-based survey of the 11th (2015) Korean Youth Risk Behavior of Korean Center for Disease Control. Data were analyzed using SPSS 18.0. The subjects consisted of 27,198 male students(50.2%) and 27,021 female students(49.8%) from 400 middle schools and 400 high schools. Results: Multiple logistic regression analysis after adjustment to demographic characteristics and oral health behavior showed experience with drinking and smoking in adolescents increased oral symptoms experienced by both male and female students (OR = 1.3, 95% CI = 1.20-1.34 / OR =1.3, 95% CI = 1.18-1.33), (OR = 1.3, 95% CI = 1.24-1.40 / OR = 1.4, 95% CI = 1.43-1.30). But the difference was not significant between genders. In terms of diet, consumption of carbonated beverages, snacks and fast food saw an increase in oral symptoms experience both gender compared with those whose "No(weekly)" in particular to women, alternatively vegetable, fruit consumption(weekly) were having less intake adolescents increase oral symptoms experience than "time daily(weekly)" intake adolescents both boy and girl especially to girl. Conclusions: There was a correlation between oral symptom experiences and health behaviors. There was also slight differences between genders, with more effect shown on female students. Based on this study, proper and systematic education of oral health management should be carried out at schools.
