The purpose of the present study was to examine the causal relationship between aggression and mobile phone dependency among high school students and to test the mediating effect of self-esteem, and to draw out implications in order to encourage proper use of mobile phone. In this paper, we proposed a research model between aggression, self-esteem and mobile phone dependency. The present study analyzed the fourth, fifth, and sixth wave data from KCYPS 2010, using the structural equation modeling. The primary results were as follows. First, the effect of high school students' aggression on mobile phone dependency was not significant. Second, high school students' aggression had a significantly negative effect on self-esteem. Third, high school students' self-esteem had a significantly positive effect on mobile phone dependency. Fourth, high school students' self-esteem could be a significant mediator between aggression and mobile phone dependency. In conclusion, theoretical and practical suggestions were discussed in order to solve the problem of adolescents' mobile phone dependency.

The purpose of this study was to identify the relationship between self-identity, Career choice factors and employment preparation activities of college students. The research subjects were the group of 2091 college students who participated in Korean Children Youth Panel Survey(KCYPS) as 7th graders. Their 7th year data in 2016 were analyzed by using SPSS 21.0, descriptive statistics, correlation analysis and regression analysis. Self identity was found significant and positive correlations between career choice factors and not employment preparation activities. and It was found that their self-identity of college students exerts a statistically significant effect on their career choice factors but not on their employment preparation activities. The research result is expected to help arrange detailed educational programs and/or self-identifying programs to help college students choose a career choice and prepare for employment-seeking activities.

The current study analyzed the 1st through 7th wave data in the 4th grade panel of elementary school from the Korea Children and Youth Panel Survey (KCYPS). The research model was tested using auto-regressive cross-lagged model. The major results were as follows. First, adolescents' school life adjustment had a positive auto-regressive effect. Second, adolescents' life satisfaction had a positive auto-regressive effect. Third, adolescents' school life adjustment was a causal predictor of life satisfaction, but not vice versa. Finally, implications in terms of enhancing adolescents' school life adjustment and life satisfaction were also discussed.

This study was to examine the group difference of parental composition (parents, single parent group) in the relationship between parental attitude (supervision, affection, rational explanation) and children's life satisfaction through ego-resilience as a mediating factor. For this, a multi-group analysis was conducted using 310 student data from the 4th panel data of the KCYPS. The results were as follows: First, parents' affectionate parenting attitude on children's life satisfaction was significant in both groups. Second, affectionate and supervisory attitude had effects to improve ego-resilience only in the single-parent group. Third, the affectionate attitude showed a significant positive effect on children's life satisfaction by mediating ego-resilience only in single parent group. This study verified the structural relationship of factors affecting children's life satisfaction and different the pattern of that relationship depending on parental composition. Finally, limitations and implications for future research were presented.

As for results, frist, in terms of individual factors, gender, physical health status, and self-resilience significantly affected depression in adolescents. Second, among school factors, learning activities and peer relationship significantly affected depression in adolescents.

The purpose of this study is to identify the effects of adolescents' experience activity satisfaction on their life satisfaction, and verify the mediating effects of sense of community between the two factors. For this, analysis has been conducted using Korean Children and Youth Panel Study (KCYPS, Ed. 6). Analysis were performed using the SPSS 24.0 program to verify the mediating effect, and the Sobel test was performed to analyze the statistical significance of the mediating effect. First, it was analyzed that the experience activity satisfaction had a statistically significant positive (+) effect on sense of community. Second, it was found that the adolescents' experience activity satisfaction had a significant positive (+) effect on the life satisfaction. Third, it was confirmed that snse of community had a positive (+) effect on life satisfaction, and at the same time, it was found that adolescents' experience activity satisfaction had a significant positive (+) effect on life satisfaction, so sense of community had a partial mediating effect.

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.
