The purpose of this study was to examine the prevalence and correlated factors of sexual behavior among high school students in Seoul A sample of 233 male and 248 female high school students were analyzed using cross-tabulation and logit regression models. Correlated factors examined include type of school, level of mothers education, perceived living status of family, whether family has two parents or not, and whether students have ever lived away from the family, whether students received reproductive health education at school and whether they have friends with sexual experience, whether students have ever smoking and alcohol drinking. The prevalence of alcohol drinking was 73% among boys and 55% among girls and the prevalence of smoking was 64% of boys and 40% of girls, whereas the prevalence of sexual activity was 27% among boys and 15% among girls. Risk taking was more prevalent among boys than among girls. Multiple risk taking behavior was common for both boys and girls. Students who did not have two parents were more likely to engage in risk taking behavior than those who had two parents. For both boys and girls, the factor that affects their own sexual activity most was having a friend who was sexually active and having an experience of living away from their family also increases the odds. For girls, the factor that affects having experience of alcohol drinking and smoking. Receiving reproductive health education at school had no effect on students sexual behavior. Much higher risk taking behavior with sexual behavior among students in Seoul implies that the overall prevalence of risk taking behavior among high school students was likely to rise as South Korea continues its modernization. In-school and community health education programs need to be modified to be effective in protecting students from risk taking sexual behavior.

This study tries to show the physical growth patterns and various adolescent characteristics by using longitudinal data for the height, weight, chest girth and sitting height of 1, 132 high school students in Seoul. And this study also tries to show what influencing factors on the physical growth of this aged population. The followings are the results. 1. The boys have their peak velocity of height when they are 12~13 years old. And the girls have when they are 10~11 years old. Peak velocity of weight for boys is at the age of 13~14. And for girls is at the age ofr11~12. Peak velocity of chest girth for boys is at the age of 12~13. And for girls is at the age of 11~12. Peak velocity of sitting height for boys is at the age of 13~14. And for girls is at the age of 11~13. So girls of this period grow more rapidly by around two years than boys. 2. The menarche of girls begins at the age of 12.4. So it begins 1.4 year before peak height velocity period. 3. Of life behavior boys contingency coefficient between essential time and height and weight is .5150 and .479 5, that between studying time and height and weight is .3344 and and .2912(In case of girls is .4735, .4321, .3247, .3134).

This study examined the effects of peer relationships, depression, and aggression on bullying and victimization among boys and girls. The subjects were 364 3rd grade students (boys, 218; girls, 146) and 368 6th grade students (boys, 186; girls, 182), that is, a total of 732 students from three elementary schools. Data were collected on bullying, victimization, peer relationships (mutual friendship, mutual antipathy, and peer popularity), depression, and aggression (overt aggression and relationship aggression) from July 12, 2012 to July 13, 2012. These data were analyzed by means of a chi-squared analysis, t-test, and a logistic regression analysis. The results revealed that there were differences by sex in the case of direct bullying and victimization but no differences in the case of indirect bullying and victimization. Among boys, the factors influencing direct bullying were depression and overt aggression, and the factor influencing direct/indirect victimization was depression. Among girls, the factors influencing direct bullying were mutual antipathy relations and relational aggression, the factors influencing indirect victimization were mutual antipathy relations and peer popularity, the factor influencing indirect bullying was mutual antipathy relations, and the factor influencing indirect victimization was peer popularity. The results of this study showed that the factors influencing bullying and victimization are differences in sex. Finally, the implications and methodology for developing bullying prevention education programs were discussed.

Longitudinal studies have shown mixed findings on the association between body image dissatisfaction and self-esteem among adolescents. This study examined the longitudinal, reciprocal influences between body image dissatisfaction and self-esteem among Korean pre- and early adolescents by using nationally representative longitudinal panel data from the Korean Youth Panel Study (KYPS). Analyses based on 2,230 participants indicated that girls' body image dissatisfaction was significantly higher than boys'. The trajectory of body image dissatisfaction increased sharply during pre- and early adolescence, but stabilized afterwards for both boys and girls. Self-esteem deteriorated rapidly initially, but began to recover as adolescent girls and boys matured. Structural equation modeling showed that reciprocal influences between body image dissatisfaction and self-esteem were detected for boys. Body image dissatisfaction among girls predicted self-esteem during the entire period, while the opposite direction from self-esteem to body image dissatisfaction emerged two years later. The present study found that, during pre- and early adolescence, body image dissatisfaction and self-esteem develop in a circular fashion by forming a vicious cycle. Implications for the development of intervention and prevention programs are discussed in consideration of age and gender.

Objectives : It has been suggested that obesity in childhood may lead early menarche and rapid bony maturation. The purpose of this study is to investigate correlation between bone maturation and obese degree in childhood in Korea. Methods : Height, body weight, BMI, percent body fat were taken 138 patients. Ultrasonic scan was taken through calcaneous of the right foot to evaluate bone age. $DA({\Delta}age)$ was calculated from the difference of bone age and chronological age, and it was used in correlation with obese degree. Results : 1. The average age of patients was $11.91{\pm}2.86$ years old in boys, $11.44{\pm}2.27$ years old in girls. 2. The average BMI was $20.92{\pm}4.53kg/m2$ in boys, $19.76{\pm}4.05kg/m2in$ girls, and average percent body fat was $25.13{\pm}8.23%$ in boys, $27.66{\pm}5.95%$ in girls. 3. The average OI(osteo index) was 37.88 in boys, 36.64 in girls, and average bone age was $12.00{\pm}2.61$ years old in boys, $11.81{\pm}2.11$ years old in girls. 4. There was significant correlation between $DA({\Delta}age)$ and PBF in boys, but no significant correlation with BMI(p<0.05). 5. There was significant correlation between $DA({\Delta}age)$ and PBF, BMI in girls(p<0.01). 6. There was significant correlation between RA and OI(p<0.01). Conclusion : It is suggested that obese degree may have an impact on early bony maturation especially in case of girls.

This study investigated the effects of mothers' perceived social support, stress, and children's temperament on parenting self-efficacy of boy's and girl's mothers among 416 Korean mothers living in Seoul, Korea. Results showed that mothers' parenting self-efficacy of boys and girls were positively related to mothers' perceived social support and children's temperament. On the other hand, parenting self-efficacy of both boys' and girls' mothers were negatively related to mothers' stress. Multiple regression indicated that mothers' perceived social support and children's temperament were the significant predictors for mothers' parenting self-efficacy of boys and girls. Husbands' support, support from social network, approach-withdrawal, and activity level-general were the significant predictors for mothers' parenting self-efficacy of boys. Husbands' support, support from social network, conflict with their children, transition of husband's job, difficulty of finance and business were the significant predictors for mothers' parenting self-efficacy of girls. Husbands' support was the strongest predicator of mothers' parenting self-efficacy of boys and girls.

This study investigated the relationship between school-age children's overt/covert narcissism with self-control and mothers' parenting. The subjects were 517 children in the 5th and 6th grades attending elementary schools located in Daegu and Gyeongbuk Province. The collected data were analyzed by t-test, Pearson's correlation, multiple regressions and SPSS Win 19.0 was used. The results were as follows: (1) School-age children's overt narcissism differed in boys and girls. However, this was not the case for covert narcissism. (2) The overt narcissism of school-age boys and girls was positively correlated with self-control. However covert narcissism was negatively correlated with self-control. (3) The active-responsive and active-restrictive parenting of mothers influenced on the overt narcissism of school-age boys, while the active-responsive parenting of mothers influenced the overt narcissism of school-age girls. Also, the active-responsive and active-restrictive parenting of mothers influenced the covert narcissism of school-age boys, while the active-responsive and passive-permissive parenting of mothers influenced the overt narcissism of school-age girls. (4) The active-restrictive parenting of mothers was the most powerful factor in the overt/covert narcissism of school-age boys and the covert narcissism of school-age girls.

The purpose of this study was to explore leacher and peer relationships and child development in two types of early childhood program; halfway kindergarten and full-day childcare. The subjects were 90 four and half year old children and their teachers enrolled in 10 kindergartens and 20 childcare centers in Seoul. Each teacher evaluated her children with six scales developed by NICHD Early Child Care Research Network(1996); child-leacher relationship, peer relationship, social competence, adaptive language, behavior characteristics, and behavior problems. The data were analyzed by ANOVA. The results of this study were as follows: First, the girls in both programs had closer relationship with their teachers than the boys. The boys in the daycare were less dependent than those of kinder; on the other hand, the girls in the daycare were more dependent than those of kinder. Second, there was no significant difference in peer relationship between the children in both centers. Third, the girls of both centers scored higher than the boys in social competence. Fourth, in the child's adaptive language, both boys and girls were well developed, but girls were higher than boys, especially in kinder Fifth, the children in both centers behaved attentively in the groups, but in particular, the girths were more attentive. Finally, most of children were received low scores in the behavior problem scale.
