This study investigated the descriptive statistics and correlation among self-identity, school violence experience, and family social capital of adolescents and examined influence of school violence experience on self-identity and moderating effect of family social capital on the relationship between school violence experience and self-identity. Data used for analysis was from 7th grade students in The Korean Children and Youth Panel Survey in 2012. Analyses were performed using the IBM SPSS program for demographic analysis, pearson correlation, and stepwise regression analyses. Results of the study were as follows: First, the average was slightly higher for self-identity, parents' affectionate attention, and awareness of their child's friends; the average was lower for misconduct experience and victimization experience; second, there was a weak negative correlation between self-identity and bully victimization; there was a positive correlation between self-identity and family social capital (parents' affectionate attention and awareness of their child's friends). Third, to investigate the effect of school violence experience (bullying and bully victimization) on self-identity, stepwise regression analysis results were as follows: Bullying had a statistically positive influence on self-identity and bully victimization had a statistically negative influence on self-identity; both parents' affectionate attention and awareness of their child's friends had a statistically positive influence on self-identity; fourth, parents' affectionate attention had a statistically negative moderating effect on the self-identity; therefore, it signifies that the relationship between bully victimization and self-identity appears differently depending on the parents' affectionate attention, which means that the parents' affectionate attention had a negative effect on the self-identity of the adolescents who were victimized by school violence.

This study examined the associations among self-disclosure tendency, self-activities and friends' responses on Facebook, and perceived usefulness of Facebook in social networking. Sex differences were also examined. Results showed that participants' self-disclosure tendency was positively related to their activities in Facebook, which were strongly related to friends-activities. Self- and friends-activities significantly increased usefulness in social networking. Regarding sex differences, the relationships between self-disclosure tendency and self-activities and between self-activities and usefulness were stronger for men, while the relationship between friends-activities and usefulness was stronger for women. These results suggest women tend to value friends' responses more in assessing relational qualities than men in Facebook contexts.

This study aimed to investigate the effect of adolescent development environment including parenting attitude, peer relationship, and school environment on delinquent behavior, and between these relationships, the mediate effect of media environment such as computer and mobile devices. The $6^{th}$ year data from Korean Children & Youth Panel Survey (KCYPS) was used and the subjects were limited to 518 students of $7^{th}$ grade who are in their early adolescence. The result shows that adolescents under more affectionate, over involvement, and abusive parenting attitude will commit delinquent behaviors more frequently, and so does alienated youth from their friends. Parenting inconsistency and communication with friends make them use computer and cell phone more often, and excessive media usage increases adolescent's delinquent behavior. In conclusion, family environment and peer relation have influence on adolescents' delinquent behavior. Therefore, there is necessity to build development environment that prevent adolescents' delinquencies like parent education program or peer communication program for example. Also, proper education program for using computer or cell phone usage can reduce adolescents' delinquent behaviors, especially when its addictive aspect was recently issued.

People tend to perceive their loved others (e.g., children, spouse, romantic partner) as their extended selves and then control over the loved others' fashion style corresponding to their self-concept. The study conceptually suggested that people's perceptions on legitimacy to interfere the others and their own fashionability would separately or interactively influence their control over the loved others' fashion style. To investigate the suggestions, an experiment with female participants in their 20's was conducted by using a scenario. The results indicated that participants' perception of legitimacy to interfere their boyfriends or their own fashionability did not have a separate effect on control over their boyfriends' fashion style. However, the legitimacy and the fashionability did have an interactive effect on the control. In particular, for high legitimacy groups, there was no difference in the control between low and high fashionability groups. For low legitimacy groups, the control was stronger in high fashionability group than in low fashionability group.

Given the 4 contexts-parents, friends, teachers and community- of adolescents, this research verified the casual relationships between each contextual support and the suicidal impulse, and the gender difference. The 4-year longitudinal data(KYPS) collected from 3,697 adolescents were used in this study. Using the Autoregressive Cross-Lagged Model, the suicidal impulse was consistently present from the 3rd grade in middle school to the 3rd grade in high school with significant stability. Gender differences were founded in the effect of parental support among the 3rd grade in middle school. Also the negative effect of friends' support on the suicidal impulse among the first grade high school students. The effects were more stronger for girls than boys. Previous supports by teachers and community had no significant effects on later suicidal impulses. These results suggest that the study of suicidal impulse needs to examine the complex support system of multiple context layers.

This study examined the effects of parental attachment and peer attachment in elementary school children upon early adolescent delinquency. The participants were 2,844 taken from data from the Korean Youth Panel Survey (KYPS). Data from secondary questionnaires data on parent and peer attachment, problem behavior, delinquent peers, and delinquency were used for this study. Data were analyzed by means of a Structural Equation Model using AMOS 5.0. Our results indicated that, firstly, parental attachment was negatively related to problem behavior for both male and female adolescents, whereas peer attachment was positively related to problem behavior only for males, but not for females. Secondly, problem behavior in childhood has a direct effect on adolescent delinquency, which also can be indirectly mediated by contact with delinquent peers. In conclusion, the path model from parental and peer attachment in early childhood to adolescent delinquency was supported only in the case of males.

This study is to test moderating effects of family support, friend's support and teacher's support in the relationship between experienced violence in school and adolescent suicidal impulse. For the purpose of this study, 298 adolescents who were experienced violence in school were sampled and surveyed. The analytical results are the followings: Moderating effects of family support, friend support and teacher support are significant in the relationship between experienced violence and depression. They are also significant in the relationship between experienced violence and suicidal impulse. On the other hand, only family support is significant in the relationship between depression and suicidal impulse. This study suggests some policy implications based on this findings.

This study analyzed the mediating effects of self-esteem and peer relationship in the effects between physical satisfaction and academic adaptation of multicultural youth. The subjects of the study were 1,064 first-year high school students at the time of the survey using the 8th Multicultural Youth Panel (MAPS) data. For data analysis, descriptive statistics, correlations, and path analysis of measurement variables were carried out using SPSS 25.0. According to the analysis, first, multicultural youth's body satisfaction has a positive effect on academic adaptation, and second, self-esteem is completely mediated in the relationship between body satisfaction and academic adaptation. Third, the relationship between multicultural youth's body satisfaction and academic adaptation has been partially mediated. The results will be used to develop basic data and programs to support healthy growth of multicultural youth. These results can be used to develop basic data and programs to devise support measures for healthy growth of multicultural youth.
