Purpose: The aim of this study was to identify sexual experiences and associated factors among middle and high school students in Korea. Methods: Data were analyzed from 74,186 participants who completed the 2012 Korea Youth Risk Behavior Web-based Survey. Descriptive statistics were used to identify the condition of sexual behavior, and a complex sample logistic regression was used to examine the factors related to sexual behavior. Results: Data showed that 4.3% of adolescents had engaged in sexual intercourse (5.9% of males and 2.6% of females). According to the logistic regression analysis for complex samples, the school level, socioeconomic status, experience of part time work, and living with parents, were all factors associated with the decision to engage in sexual intercourse among boys and girls. In particular, sex education in schools was associated with a reduced risk of sexual intercourse. Conclusion: The results of this study highlight the importance of developing a program that focuses on enhancing sex education and promoting refusal and better decision-making skills in order to effectively reduce the likelihood of sexual experience among adolescents in Korea.

The courtship and fighting behaviors and the sexual dimorphism of the salamander Hynohius leechil were studied. The parameters, snout vent length, body length (from snout to tail tip), and proportion of snout vent length to body size were larger in the female than the male. Five physical parameter in males were significantly correlated with one another, body length, snout vent length, head width, tail vent length, and tall depth, while all, except tail depth, were significantly correlated in females. Sexual behavior of H. leechIl involved external fertilization and consisted of three stages, identifying the female, aifrading the female, and insemination. The identification stage consisted of a positive advance by the male toward the female and display of snout contact. The male attracted the female with chin rubbing, tail undulation, smelling, and digging displays. The insemination process consisted of four phases, amplex, separating egg sacs from the female's cloacal, fertilizing eggs, and post fertilization. liighting behaviors were quite simple. The attacking male would generally bite the opposite male's upper chin or hind limbs and then shakes his head two or three times. The bitten male, which in most cases was of a dissimilar body size, quicidy escaped from the attacking male. After fighting, winning male usually displayed rapid tail undulation.

Seventy four Holstein heifers were randomly assigned over three trials to PRID-7+PG-6 and Synchromate B-9 regimens to synchronize estrus cycle for embryo transfer. Sexual behaviors; moounting, standing, orientation, chin-resting, sniffing, licking, rubbing and butting, vaginal swelling and mucus discharge were observed between 06-08, 12-14 and 18-20 h on 1st day and 00-02, 06-08, 12-14 and 18-20 h on 2nd day after removal of hormones. Synchromate-B treatment (81.6%) showed higher synchronized estrus rate than PRID treatment (77.8%) during observation period. Standing estrus was observed within 74 h after PG injection in PRID and within 52 h after removal of implant in Synchromate-B. About 68% of heifers in PRID and 74% of heifers in Synchromate-B showed standing estrus between 0-14 h on 2nd day after removal of the hormones. Synchromate-B resulted in a tighter synchrony of standing estrus than PRID. Incidence of average mounting and standing per head during observation period was 22.3 and 16.6 in PRID and 28.1 and 13.6 in Synchromate-B. The PRID showed peak in active mounting at 18-20 h on 1st day, however, the Synchromate-B showed at 0-2 h on 2nd day after removal of hormone. Active standing was shown between 18 h on 1st day to 20h on 2nd day in PRID, however, between 0-14 h on 2nd day after removal of hormone is Synchromate-B. There was slight difference in pattern of active mounting and standing during estrus between PRID and Synchromate-B. Conception rate of synchronized heifers transferred with fresh and frozen embryos by non-surgical and surgical methods was higher in synchromate-B (62.5%) than in PRID (38.5%). Chin-resting showed highest incidence among 6 sexual behavioral components in the both treatments. Synchromate-B showed higher incidence of chin-resting (16.6) than PRID (10.7). Synchromate-B group showed also higher incidence of orientation, sniffing and butting than PRID group. Synchromate-B resulted in more active sexual behaviors than PRID. The pattern of incidence of chin-resting, licking and butting was almost symmetrical in PRID with their peak values at 6-8 h on 2nd day, however in Synchromate-B chin-resting and sniffing was symmetrical with their peak values at 12-14 h on 2nd day after removal of hormone. There was tendency to increase vaginal swelling according to time passage of synchronized estrus in the both treatments. Incidence of mucus discharge in Synchromate-B was slightly higher than in PRID. Twenty to 40% was false negative in conception rate by tall painting before re-estrus day as judged by rectal palpation.

Purpose： This study reviews the Youth Risk Behavior Surveillance System (YRBSS) in the United States. This review focuses on the purposes, questionnaires, survey methods, and use of survey results. The author also discussesthe establishment and use of Korean Youth Risk Behavior Surveillance System. Results：The YRBSS was developed in 1990 to monitor priority health risk behaviors that contribute to the leading causes of death, disability, and social problems among youth and adults in the United States. The purpose of YRBSS is to determine the prevalence of health risk behaviors, to assess the trend of health risk behavior prevalence, provide comparable data, monitor progress toward achieving the Healthy People 2010. The questionnaires inquire about health-related behaviors, including tobacco use, unhealthydietary behaviors, inadequate physical activity, alcohol and drug use, sexual activity, behaviors that contribute to unintentional injuries and violence. The results of YRBS have been used to estimate the prevalence of risk behaviors among youth, to set goals for school health programs, for training and development of health program personnel, for the development of health education curriculum, to support enactment of health-related regulations, and to support funding for futher research. Conclusions： The YRBSS represents a potentially valuable program that can be applied in Korea. Assessment of risk behaviors among Korean youths will provide invaluable insight for many potential purposes.

Purpose: This research examined the trend of school health education, using online research data on health behaviors of adolescents. Then it compared the health perceptions, healthy life practice, and health risk behaviors between students who received health education and students who did not. In addition, it predicted the impact of health education on health risk behaviors of students. Methods: Data from 72,435 participants of this survey were analyzed. Statistical analyses were performed on weighted data using the complex sampling design. Results: In the results of the research, general high schools students had the lowest rate of receiving health education, while sex education was the most actively held throughout the all locations. Next, medium-small cities had the lowest rate of receiving health education. Regarding health risk behaviors, students receiving health education had significantly lower rates of smoking, drinking, and sexual intercourse. Conclusion: This study shows that healthy life practices by students improves with the inclusion of health education, thus indicating that schools should invest in health education. This research generated evidence for the first time in Korea that school health education has a positive impact on health risk behaviors and provides basic data for policy development of school health education.

This study analyzed the health risk behavior of Korean college students by comparing them based on the college location (Seoul vs. non-Seoul). Converging analyses of health risk behaviors (drinking behavior, sex, suicidality) and health risk factors (mental health, stress) were attempted. The results showed the 23% of students were at risk of serious drinking problem, and the 52.6% of students consumed alcohol once in every other week or more often. In case of the sexual behavior, 40.6% had sexual experience. Importantly, the 25.4% and the 20.3% of college students in Seoul and non-Seoul area, respectively, had two or more sexual partners. Also, students in non-Seoul area had a tendency of the higher level of suicidality, and the lower level of mental health. Overall, the self-respect score was the only statistically significant factor showing the Seoul/non-Seoul difference. These results may be able to intervene the health risk behaviors of college students.

Based upon the first national sample of adult men and women, the study aims to examine the prevalence of chid sexual abuse in Korea and factors related to the incidence of child sexual abuse. The results of the study show that 20.8% of the sample experienced one or more types of sexual abuse in their childhood, which indicates that Korean society is not any longer immune to child sexual abuse. With regard to how to cope with sexual abuse, "not informed to anyone and did not get any help at all" is the most major one for all types of sexual abuse. Even those who got help were reported to depend heavily upon private routes such as parents, relatives, or friends, indicating the urgency of establishing systematic intervention schemes for the problem. The results of a logistic regression analysis show that gender of the child, involvement in delinquent behaviors, economic status of the family, number of siblings, and residence in high-crime region are significantly related to the incidence of child sexual abuse. These results of the study would be expected to provide a useful guideline for developing policies or intervention programs aimed to prevent or address child sexual abuse.

The purpose of this research was to identify the relationship between specific personality characteristics and maladaptive social behaviors in order to contribute to development of a pragmatic intervention for the prevention of sexual aggression. This was accomplished by examining the mediating effects of entitlement rage (K-PNI) or sociosexuality (K-MSAS) on sexual aggression, and moderating effects of cognitive emotion regulation strategies (K-CERQ) or state empathy (K-CMEM) on sexual aggression in narcissistic men. Data were obtained from male college students (n = 264) who completed self-report questionnaires, such as K-NPI and K-CMEM, and hierarchical regression analysis was applied to examine these relationships. Both entitlement rage and cognitive emotion regulation strategies were found to be unassociated with sexual aggression. Rather, sociosexuality was the mediating factor between narcissism and sexual aggression, Whereas state empathy was a moderating factor between narcissism and sexual aggression. These findings indicate a tendency for sociosexuality to increase sexual aggression in males. However, individuals with low state empathy are more likely to show sexual aggression than those with high state empathy, indicating that intervention for increased state empathy may be a more effective treatment than cognitive emotion regulation strategies.

The purposes of this study were to investigate female adolescents' attitude toward the social instrumentality of appearance and to examine the effects of the attitude toward the social instrumentality of appearance on female adolescents' body satisfaction and appearance management behaviors. The subjects for this study were 435 female middle school and high school students in Daejeon and Chungnam province. The research method was a survey and the measuring instruments were a self-administrated questionnaire with 4 parts (social instrumentality of appearance, body satisfaction, appearance management behaviors, and subjects' demographics attributions). The data were analyzed by Cronbach's ${\alpha}$, factor analysis, cluster analysis, ${\chi}^2$ test, t-test, using SPSS statistical program. The results were as follows. Three dimensions (the utility of interpersonal relationship, sexual partnership and social achievement) were emerged on social instrumentality of appearance, and female adolescents were divided into 2 groups(unreceptive group and receptive group) by social instrumentality of appearance. Social instrumentality of appearance had significant effects on female adolescents' body satisfaction and appearance management behaviors. The group who had receptive attitude toward the social instrumentality of appearance was showed the lower body satisfaction and more positive attitude to perform appearance management behaviors including clothing and accessories management, fitness, skin and hair care, and plastic surgery than unreceptive group.

To evaluate effect of Gamimajeonojahwan(GMOH) water extract on sexual functions, we orally administered GMOH exract(1,100㎎/㎏) for four weeks in male rats impaired by 2,3,7,8-tetrachlorodibenzo-p-dioxin(TCDD) and ketoconazole(KZ). And we investigated the sexual behaviors such as mount latency, mount frequency, intromission latency, intromission frequency, ejaculation period and ejaculation latency. Serum testosterone concentrations also are evaluated in GMOH-and/or vehicle-treated male rats. The results were obtained as follows: GMOH inhibited the increase of intromission latency by TCDD in male rats. GMOH inhibited the decrease of intromission frequency by TCDD in male rats. GMOH inhibited the increase of ejaculation latency by TCDD in male rats. GMOH inhibited the decrease of serum testosterone concentration by TCDD in male rats. GMOH inhibited the decrease of serum testosterone concentration by KZ in male rats. These results suggest that GMOH water extract is active in improving sexual functions and protecting a decrease of testosterone concentrations induced by TCDD and KZ in male rats.
