The purpose of this study was to analyze the longitudinal causal relationship between caregiver relations and peer relations of children in out-of-home care. We analyzed the three years(2011-2013) of longitudinal data from the Panel Study on Korean Children in Out-of-Home Care. The autoregressive cross-lagged model (ARCL) was used to measure the longitudinal causal relationship between caregiver relations and peer relations. As a result, first, caregiver relations and peer relations showed stability over time. In other words, the results of the measurement at three time points showed that the caregiver relations and peer relations at the previous time had a significant effect on the caregiver relations and peer relations at the later time point. Second, the previous caregiver relations had a significant effect on the subsequent peer relations over time. Third, the previous peer relations had a significant effect on the subsequent caregiver relations over time. This study confirmed the interrelationships of caregiver relations and peer relations of children in care by examining the longitudinal data using the longitudinal analysis method.

The purpose of this study is to examine moderating effect of social relationship on the relationship between academic stress and psychological health among of adolescents. This data used in this study used data was derived from the wave 2-4(2004-2006) of Korean Youth Panel Study (KYPS). The results show that social relationship(parent-child relationship and peer relationship) had a moderating effect on academic stress and psychological health of adolescents. In short, it was verified that in the case of good social relationship, academic stress could actually buffer the effect of psychological health. However, it terms of parent-child relationship, it was not confirmed to have a moderating effect on academic stress and psychological health in the 11th grade. The results from above suggest that schools and related facilities adolescent should consider the program to reinforce social relationship and the timing of the intervention.

The present longitudinal study examined reciprocal influence between self-esteem and academic achievement using cross-lagged autoregressive model. This study employed data(four wave) from Korea Youth Panel Survey. Participants were 300 students(143 boys, 157 girls) who were 4th graders in 2004 and 7th graders in 2007. The results of this study indicated that 4th graders' self-esteem influenced 5th graders' academic achievement, in turn, 5th graders' academic achievement influenced 6th graders' self-esteem. However, students' self-esteem in 6th grade did not influence their academic achievement during 7th grade. Conversely, 6th graders' academic achievement influenced 7th graders' self-esteem.

This study examines the effect of children's school satisfaction on academic achievement using the Seoul Children Panel Study data. More specifically, this study aims to add new knowledge to understaning the causal relationship between school satisfaction and academic achievement by taking into account of temporal order of the events of interest. In the analysis, we examine the effect of school satisfaction at the 4th- and 5th- grades on academic achievement at the 6th grade while controlling for the other factors including the level of academic achievement at the 4th grade. The results show that children's school satisfaction significantly affects their academic achievement. The findings of this study have implications for the school social welfare programs that attempt to improve academic achievement of children by raising the level of school satisfaction among children.

Objective: The purpose of this study was to identify the longitudinal relationship between child maltreatment and adolescent suicidal ideation. Several studies suggest that child maltreatment is associated with adolescent suicidal ideation. However, these studies have not focused on the duration of child maltreatment. Methods: Participants were 420 adolescents (52.6% male; 47.4% female) involved in the Korea Welfare Panel Study. Data were collected via youth self-report in 2006, 2009, and 2012. A self-report assessment of children and youths' experiences of physical, emotional, or neglect had been surveyed longitudinally. Questionnaires on adolescent suicidal ideation were answered in 2012. A growth mixture model and multiple regression were conducted using Mplus 5.21. Results: The study results showed that 93.5% of the children had experienced no maltreatment; 6.5% had experienced increasing maltreatment longitudinally. The trajectory of increasing maltreatment was positively associated with adolescent suicidal ideation. Conclusion: These results show that children suffering from chronic maltreatment are subject to a high risk of suicide and therefore require continuous supervision and management.

This study examines the effects and process of housing poverty on children's physical health, internalizing problems and academic achievement using the first Korea Welfare Panel Study. The results show that sub-minimum standard housing condition and housing expenditures have increased the housing instability, non-study activities, while harming parent's health and decreasing non-housing expenditures. And this process negatively affects children's internalizing problems and academic achievement. The findings of this study have value for controlling the confounding factors as income poverty, neighborhood poverty and characters of household. This research is significant in that it develops the theoretical model of housing poverty and suggests the necessity of interventions to alleviate housing poverty.

This study analyzed whether depression and social support had a mediating effect between income status and life satisfaction of middle-aged and elderly people with disabilities using data from the 15th year of the Korea Welfare Panel data. As a result of the analysis, first, the income status of the middle-aged and disabled was depressed(B=.241, p<.001), social support(B=-.167, p<.001), and life satisfaction(B=-.277, p<.001) was confirmed to have a direct effect. Second, the mediating effect of depression and social support was verified on the influence between the income status of middle-aged and disabled people between life satisfaction. Third, it was confirmed that depression and social support had a multi-mediating effect between the income status and life satisfaction of middle-aged and disabled people. Therefore, an income support system that supports middle-aged and disabled people to live at an appropriate level should be prepared. In addition, in order to increase the life satisfaction of middle-aged and disabled people, it is necessary to intervene in mental health support services that can actively cope with depression and to expand the social support network.

Objective: This study aimed to examine the predictors of indoor play behaviors using cluster analyses. Methods: Data from 963 children (age 4 years) who participated in the $5^{th}$ phase of the Panel Study of Korean Children, their parents, and their teachers were analyzed using K-means clustering analyses, F-tests and multinomial logistic regression analyses. Results: The clustering analyses revealed three distinctive profiles: positive-theme oriented, general-exploratory/manipulative, and negative-exploratory/manipulative groups. Child characteristics, including cognition, language, and social level, and teachers' age were significantly associated with the groups in a different way; the clusters were partially different in the gender and creativity of children, interaction level of teachers' interaction, classroom environment, and program types that children attended. Conclusion: Findings revealed three clusters of play behaviors and highlighted the importance of the ecological variables that determined the clusters.

The primary purpose of this study is to analyze the decreasing effect of public and private income transfers on poverty rate. Two year data of Korean Labor and Income Panel Study (KLIPS, 1998, 1999) are used for the analysis, and 1/2 of median income and 1/3 of mean income are adopted to measure poverty rate. Although private income transfer contributes more to reduce the rate than the public transfer, the main effect for decreasing poverty rate is forced by the wage. Statistically significant variables that affect to the exit of poverty based on the logistic regression analysis are number of family members(-), wage(+), property income(+), social insurance benefit(+), and the transfer income(+). Therefore, the future policy should be more related with the active labor market policy for developing better human resources among the poor family.

The purpose of the present study was to test the impact of depression on mobile phone dependency among elementary school students, to test the mediating effect of self-esteem between depression and mobile phone dependency, and to draw out theoretical and practical implications in terms of preventing or reducing mobile phone dependency. Based on previous studies, a longitudinal research model between the aforementioned three variables has been identified. The present study analyzed the 4th, 5th, and 6th wave data from Korea Children and Youth Panel Study 2010 (KCYPS 2010). The major results were as follows. First, depression could have a significant negative effect on self-esteem. Second, self-esteem could have a significant negative effect on mobile phone dependency. Third, the influence of depression on mobile phone dependency was not significant. Fourth, gender could be a significant moderating variable between depression and self-esteem. Finally, a number of implications of these findings were also discussed.
