This study aims to investigate various cultural activities of the Korean youth including the subcultural and popular cultural activities and their characteristics and influences on the youth fashion during the period 1996-2004. This study employs a qualitative approach based on the previous discussions of relevant literatures dealing with Korean youth culture and their fashion styles. The result of the study shows that the most prominent characteristic in youth fashion of the period was 'bricolage.' The appearance of 'Seotaiji' and the activities of his group laid the cornerstone of youth culture in the early 1990's. The influence of postmodernism changed the conventional sexism and androgynous outfit thrived. The androgynous effect also had strong influence on men's fashion in what turned out to be Metro-Sexual in early 2004. During the period 2000-2004 the postmodernism regained its popularity both in culture and fashion. 'Body' was also an important part of youth culture and has become the most popular and prevalent word of this era. At the same time the 'Well-Being' and sports look were the new trend of youth fashion. Sports look, also known as Caports, is one of these new trends and the most important youth fashion style like mix & match reformation. The youth became more and more aware of the body image and were interested in fashion as well. This trend awareness of their body and Well-Being image as well as their inclination to the fashion in the youth is expected to continue. Therefore the fashion industry, as their marketing strategy, needs to analyze the characteristics of the cultural trends among the youth and to prepare for the future need of youth fashion.

The Ministry of Health and Welfare of Japan has set up six research groups concerning the endocrine disrupting chemicals. One of these projects was "A study on development of testing methodology for health effects due to exposure of environmental endocrine disruptors". In this paper, three topics are described. In OECD collaboration for pre-validation of uterotrophic assay, the most sensitive response to ethnyl estradiol was noted in the ovarectomized rats treated subcutaneously for 7 days. Secondly, it was suggested that changes of the serum $\alpha_{2u}$-globulin level may be a sensitive parameter for detecting the estrogenic activities of chemicals. Finally, development of the sexually dimorphic nucleus of preoptic area in the brain oj male rats was inhibited by the treatment with estrogenic chemicals, and their masculine behaviors and reproductive abilities were impaired after sexual maturation. In conclusion, these parameters are considered to be sensitive endpoints for testing estrogenic chemicals.chemicals.

Purpose: This study aimed to identify the prevalence of alcohol and cigarette use and assess its relationship with socio-environmental, psychological, violent and behavioral factors among a sample of high school students from Lima and Callao, Peru. Methods: We utilized the data from a cross-sectional study conducted by the Yonsei Global Health Center in collaboration with the Korea International Cooperation Agency (KOICA) Peru office in November 2016. The total sample size of this study was 1,477 students. For analysis, we used bivariate and multivariate logistic regression to calculate the unadjusted and adjusted odds ratios and their respective 95% confidence intervals. Results: The current prevalence of alcohol and cigarette use among adolescents was found to be 24.2% and 12.1%, respectively. Alcohol use was affected by age, friends' alcohol use, experience of physical fighting, and involvement in other risk behaviors (smoking, drug use, and sexual intercourse). Cigarette use was affected by perceived academic performance, friends' cigarette use, and involvement in other risk behaviors (drinking, drug use, and sexual intercourse). Furthermore, students who received affection from their parents and whose parents monitored their activities were less likely to report using both alcohol and cigarettes. Conclusion: Alcohol and cigarette use among Lima and Callao adolescents is affected by socio-environmental, violent and behavioral factors. Alcohol and cigarette use prevention initiatives should promote positive parenting practices, family togetherness, and a supportive school climate. In addition, it is needed to establish peer-led programs that promote behavioral changes in students and strengthen social relations without the presence of alcohol, cigarettes, and other harmful substances.

Sex hormones not only regulate external sexual characteristics but several internal biochemical processes. It is well accepted that life-span of female is longer than that of male. Life-span is closely related with aging process in which free radicals are known to be involved. We investigated the effect of testosterone on free radical generating systems and lipid peroxidation based on the sexual difference. Lipid peroxide levels of male and female mouse were increased proportionately with age, especially in male mouse. Increase in enzyme activity of aldehyde oxidase with age was observed in male mouse, while no siginificant change in enzyme activity was found in female mouse. Enzyme activity of xanthine oxidase also showed similar results. It, however, was not significant statistically. Lipid peroxide level and xanthine oxidase type conversion ratio of male and female mouse liver homogenate incubated at $37^{\circ}C$, increased remarkably in proportion to incubation time, especially in male mouse. Lipid peroxide level and aldehyde oxidase activity were measured in normal male mouse, castrated mouse and testosterone treated-castrated mouse. Castrated mouse group showed decrease in lipid peroxide level and aldehyde oxidase activity compared with normal group. Treatment of castrated mouse with testosterone, however turned the level of lipid peroxide and aldehyde oxidase activity back to normal. From the above results, it might be concluded that testosteron could increase the activities of free radical generating enzymes which would result in the formation of lipid peroxide, consequently leading to aging.

암컷의 배우자 선택은 여러 수컷들이 가지고 있는 다양한 특성에서 각기 다른 종류의 정보를 수집, 종합하여 가장 최적의 개체를 배우자로 결정하는 매우 복잡한 행동이다. 본 연구에서는 순차적인 교배 시스템($4{\times}4$ block breeding)을 이용하여 각시붕어(Rhodeus uyekii) 암컷의 배우자 선택방식을 조사하였고, 가중과 비가중 유전적 이득의 상대적 기여도를 추정해 보고자 하였다. 실험장치 내에서 총 48회의 암, 수간 배우자 상호작용이 관찰되었고, 암컷은 일반적으로 카로티노이드 혼인색 발현이 강한 수컷들을 배우자로 선호하는 것으로 나타났다. 하지만, 배우자 선호 정도가 개체에 따라 차이가 나타나므로, 비가중적 요소도 암컷이 배우자를 선택하는데 있어 기여를 할 것으로 예상된다.
