This study examined the effect of digital technologies on adolescent mental health; attention deficit, aggression, depression. Furthermore, we investigated the role of parenting style and peer attachment as they might have effects on digital technologies. Using two-wave longitudinal data, we conducted longitudinal analysis from the Korean Children and Youth Panel Survey done in 2015 and 2016. Results showed that computer and internet usage for learning purpose has a positive effect on mental health, while computer games and social media have negative effects. Also, the positive effects of learning on depression indicated stronger in adolescents who felt less affection from their parents. On the other hand, the negative effects of computer games and social media could be moderated by both parenting style and peer attachment. Implications of these results and directions for future research are discussed.

Purpose Cyber deviance of adolescents has become a serious social problem. With a widespread use of smartphones, incidents of cyber deviance have increased in Korea and both quantitative and qualitative damages such as suicide and depression are increasing. Research has been conducted to understand diverse factors that explain adolescents' delinquency in cyber space. However, most previous studies have focused on a single theory or perspective. Therefore, this study aims to comprehensively analyze motivations of juvenile cyber deviance and to develop a predictive model for delinquent adolescents by integrating four different theories on cyber deviance. Design/methodology/approach By using data from Korean Children & Youth Panel Survey 2010, this study extracts 27 potential factors for cyber deivance based on four background theories including general strain, social learning, social bonding, and routine activity theories. Then this study employs econometric analysis to empirically assess the impact of potential factors and utilizes a machine learning approach to predict the likelihood of cyber deviance by adolescents. Findings This study found that general strain factors as well as social learning factors have positive effects on cyber deviance. Routine activity-related factors such as real-life delinquent behaviors and online activities also positively influence the likelihood of cyber diviance. On the other hand, social bonding factors such as community commitment and attachment to community lessen the likelihood of cyber deviance while social factors related to school activities are found to have positive impacts on cyber deviance. This study also found a predictive model using a deep learning algorithm indicates the highest prediction performance. This study contributes to the prevention of cyber deviance of teenagers in practice by understanding motivations for adolescents' delinquency and predicting potential cyber deviants.

The purpose of this study is to explore methods to prevent and improve the problem of overdependence on smartphones by analyzing the differences in satisfaction with college life satisfaction of freshmen. For this, data on freshmen of KCYPS were extracted and used. The data were analyzed using non-hierarchical cluster(K-means) analysis, T-test, one-way ANOVA, and Scheffé tests. The results of this study are as follows. First, it has been shown that freshmen who are overdependent on smartphones experience inconvenience in their daily life, withdrawal and anxiety, and resistance. Second, there is no significant difference in the level of satisfaction with college life according to gender(t=-.015, p<.05). Third, it is shown that the level of satisfaction with college life of overdependent freshmen on smartphone is significantly lower compared to that of average and moderate dependent freshmen. Based on the results, it was suggested that university-level efforts such as emotional support and learning strategy support are needed for freshmen who are overdependent on smartphones.

This thesis aims to investigate the mediatorial effect of peer attachments and self-esteem between the child abuse by their parents and the adolescents' life-satisfaction. In order to achieve this goal, the author analyzed the data gathered over 6 year period, which subjected 1823 third-year middle school students, a sample selected by the stratified-multilevel-sampling from the "Korean Children and Youth Panel Survey". The author collected the source material by means of SPSS WIN. 21.0 Program, frequency analysis, technological statistic analysis, relative analysis, path analysis (for satisfaction), and sobel test, etc. The results of analysis are as follows: Firstly, the child abuse by their parents has had a significant negative maladjustment on the participants' life satisfaction level. Secondly, the peer attachments had an influence on partial mediatorial effect between the child abuse by their parents and adolescents' content(satisfied) lives. Lastly, the self-esteem had an influence on the complete mediatorial effect between the child abuse by their parents and the adolescents' happy lives. The author gave an improved counterplan for peer attachments and self-esteem. The author suggests following researchers to include the impact of versatile environmental factors on adolescents' life satisfaction level which was excluded in the present research.
