This study was to investigate factors influencing the school adjustment according to gender and body mass index (BMI) of middle school students who participated in the 2nd-wave Korea Children and Youth Panel Study (KCYPS). This study used a crosssectional design with secondary analysis with KCYPS. The variables were parental interest, behavioral problem, aggression, attention problem, somatic symptom, social withdrawal, depression, and academic achievement. The data were analyzed with descriptive statistics, Pearson's correlation coefficients, and multiple regressions. School adjustment was significantly associated with academic achievement high, explaining 11.3~19.1% of the variance in boys. School adjustment was significantly associated with attention problem, explaining 14.9~42.4% of the variance in girls. Factors influencing school adjustment were significantly different according to gender and BMI. To improve the school adjustment, it is necessary to develop gender-specific school adjustment promotion programs according to BMI.

The purpose of the present study was to investigate the relationship between perceived parenting style and life satisfaction among adolescents transitioning from middle to high schools and to ascertain whether self-esteem functions as a mediating variable between the two aforementioned variables. Based on the results of literature review, a research model, in which there were perceived parenting style, self-esteem, and life satisfaction as latent variables, was designed. The current study analyzed the 6th and 7th wave data of the 4th grade panel of elementary school from the Korea Children and Youth Panel Survey (KCYPS). Major results were as follows. First, perceived democratic parenting style had a significant positive effect on life satisfaction whereas controlling parenting style did not have a significant impact on life satisfaction. Second, self-esteem partially mediated the effect of perceived democratic parenting style on life satisfaction. Third, self-esteem fully mediated the effect of perceived controlling parenting style on life satisfaction. Finally, implications and recommendations were provided to improve parenting style and to enhance self-esteem of adolescents experiencing school transitions.

This study focuses on the application of the data mining technique logistic regression analysis and decision tree analysis to the domestic public database called Korean Children Youth Panel Survey (KCYPS) to derive a series of important factors affecting the enhancement of life satisfaction of domestic youth. As a result, the general impact factors on life satisfaction for each grade were derived from logistic regression. Using decision tree analysis, we came to conclusions that those factors such as depression, overall grade satisfaction, household economic level, and school adaptation play crucial roles in affecting high school adolesscents' life satisfaction.

The study used cross-lagged path modeling to examine the longitudinal associations between self-esteem and community spirit among adolescents. This is a longitudinal study designed to examine the developmental changes of adolescents' self-esteem and community spirit in Korea. This study used the data collected by the Korean Children and Youth Panel Survey (KCYPS) from 2014 through 2016. Participants were surveyed from the 5^th grade to the 7^th, which belonged to the 1^st elementary school cohort panel of the KCYPS. To be used as the data of this study, children should have all information at 3-time points: the 5^th grade; 6^th grade; 7^th grade. The collected data were analyzed with PSAW 18.0 and AMOS statistical program. The participants in this study were 903 males (51.6%) and 847 females (48.4%). The level of self-esteem was 3.29±.51, 3.19±.55, and 3.15±.57 point at 5^th grade, 6^th grade, and 7^th grade each. The level of community spirit was 3.12±.52, 3.09±.59, 3.15±.55 point respectively. Community spirit from elementary school to middle school is consistently predicted by previous self-esteem. Likewise self-esteem has a significant predictive effect on subsequent community spirit.

The purpose of this research is to identify the longitudinal reciprocal relationship between family social capital and self-esteem of adolescents. Five waves of panel data from the Korea Youth Panel Survey were employed for this research. Korean Adolescents Policy Research Institute collected the first wave data in 2004 from elementary school children in 4th grade. Autoregressive cross-lagged modeling was performed to analysis the longitudinal reciprocal relationship between family social capital and self-esteem. The major findings were as follows. First, stability coefficient of family social capital and self-esteem showed that both variables were significantly stable over time. Secondly family social capital(t) had statistically significant effect on self-esteem(t+1), whereas self-esteem did not predict family social capital at a statistically significant level. These findings suggest that family social capital and self-esteem is stable overtime, and that obtaining family social capital and establishing positive self-esteem is important during this period in childhood. In addition, the results show that family social capital affects self-esteem, which highlights the importance of family social capital accumulation on the development of adolescent self-esteem.

This study attempted to derive high-risk groups of adolescent status delinquency(ASD) and to identify related factors. This study was conducted with 1,979 adolescents enrolled in the first year of high school, data from the 7th year of the 4th grade panel of the Korean Children and Youth Panel Survey. Classification and regression tree analysis method was used. The ASD group was 264, which was 13.3% of the total. The high-risk group for ASD is that is male who has a low perception of positive parenting style. Positive parenting style was found to be the most important influencing factor in ASD, followed by gender, emotional problems, relationship with teacher, and achievement value. In order to prevent ASD, it is necessary to develop a parenting education program and an intervention program specialized for male adolescents. In addition, interventions that comprehensively deal with emotional problems such as depression and social withdrawal are required, going beyond the previous interventions that focused on aggression. In particular, it has been found that relationship with teachers is the most important influencing factor in the school environment. Through education on the causes and consequences of ASD and training on counseling techniques, the promotion of relationships with teachers will act as a protective factor to prevent ASD.

The purpose of this study was to raise validity of the result through using national data, to analyze the effect of children's smartphone addiction on aggression and moderating effect of parenting styles on the relationship between children's smartphone addiction and aggression. The data were obtained from 4th waves of KCYPS(Korean Children Youth Panel Study), and 1,686 4th graders in elementary schools who have smartphone were analysed. To achieve the purpose, this study executed frequency analysis, descriptive statistic, and hierarchical multiple regression analysis through SPSS 21.0. The results of this study are as follows: First, the higher children's smartphone addiction level, the higher children's aggression goes. Second, parents' supervision, affection, neglect have moderating effects on the relationship between children's smartphone addiction and aggression which means parenting styles could reduce children's aggression despite serious smartphone addiction. Based on these results, this study suggests that the combination of preventive discipline of smartphone addiction and parental education program is needed to reduce children's aggression which is main factor of bullying. In addition, this study suggests the establishment of special arrangement such as 'shut down' for smartphone addiction prevention.
