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 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.

The purpose of this study is to investigate the effects of high school students' academic problems such as academic stress and low academic achievement on suicidal ideation and the mediating effects of individual-level risk factors (e.g., depression, aggression) and protective factors (self-esteem, emotion regulation) on the relationship between academic problems and suicidal ideation. This study used data of three waves(2005-2007) from the Korea Youth Panel Survey(KYPS). The analyses were conducted on 2,093 academic high school students, who participated in this panel study. The results from structural equation modeling show that academic stress has positive effects on depression and aggression, but negative effect on self-esteem. Low academic achievement has positive effect on aggression but negative effect on self-esteem. Depression and aggression as individual-level risk factors have positive effects on suicidal ideation. In contrast, self-esteem and emotion regulation as individual-level protective factors have negative effects on suicidal ideation. The relationship between academic problems and suicidal ideation is mediated by depression, aggression, and self-esteem. Based on the study findings, practice implications for youth welfare are discussed to screen high-risk youths and to prevent adolescent suicide in advance.

This study examines the scale of occurrence of Catastrophic Health Expenditure, and identifies the factors influencing Catastrophic Health Expenditure among disabled elderly households. Catastrophic Health Expenditure is defined by when the households' health care spending out of ability to pay exceeds 10%, 20%, 30%, and 40%. This study used the 2008, 2009, and 2010 surveys of the Panel Survey of Employment for the Disabled(PSED) to explore how gender, age, spouse, the level of education, the degree of disability, the type of disability, disability duration, subjective health status, chronic disease, the number of household members, the proportion of disabled households, the proportion of working households, the proportion of aged households, the type of poverty, household income, net asset, determine Catastrophic Health Expenditure among disabled elderly households. The study examines the frequency of Catastrophic Health Expenditure with 726 households, and conducted the panel logit model. The empirical results show that Catastrophic Health Expenditures are significantly related to age, spouse, the type of disability, subjective health status, chronic disease, the number of households, the proportion of disabled households, the proportion of aged households, the type of poverty. This study showed that the health care safety net in South Korea was insufficient for disabled elderly households and that a policy should be established in ordered to protect disabled elderly households from occurrence of Catastrophic Health Expenditure.

The purpose of this study was to investigate the effects of attachments to parents, teachers, and friends on delinquencies among elementary school students. Participants were 2844 elementary school students from the 2004-2006 panel 2 data of the Korea Youth Panel Survey(KYPS). For analyses of research questions, frequencies, descriptive statistics, independent sample t-tests, Pearson correlations and multiple regression analysis were used with SPSS 12.0. Results of the study indicated that : (1) For boys, attachments to parents reduced delinquencies more than for girls. However, for girls, attachments to teachers reduced delinquencies more than for boys. (2) Attachments to friends influenced delinquencies negatively in the 4th grade, but influenced delinquencies positively in the 6th grade. (3) When boys and girls kept in touch with delinquent peers, attachments to parents largely influenced delinquencies.

The purpose of this study is to examine the mediating effect of self-esteem on the effect of family relationship satisfaction on depression among the elderly and to draw implications for the social welfare field. For this study, raw data from the 16th Korean Welfare Panel Survey were used for analysis, and a sample of 4,310 elderly people aged 65 years or older was selected as respondents. The collected data were subjected to frequency analysis and correlation analysis using IBM SPSS 24.0, and the Process Macro of SPSS proposed by Hayes (2018) was used to examine the mediating effect. The results of the significance test of family relationship satisfaction on depression showed that family relationship satisfaction was significant, i.e., the higher the level of family relationship satisfaction, the lower the depression. In addition, the results of the significance test of the effects of family relationship satisfaction and self-esteem on depression showed that family relationship satisfaction had a significant effect, and the mediating variable, self-esteem, had a significant effect on depression. Therefore, this study aims to identify the characteristics of family relationship satisfaction among the elderly and provide policy suggestions and social work practice directions to reduce the level of depression among the elderly.

Background and objective: This study identifies whether children's planning-organizing executive function can be significantly classified and predicted by home environment quality and wealth factors. Methods: For empirical analysis, we used the data collected from the 10th Panel Study on Korean Children in 2017. Using machine learning tools such as support vector machine (SVM) and random forest (RF), we evaluated the accuracy of the model in which home environment factors classify and predict children's planning-organizing executive functions, and extract the relative importance of variables that determine these executive functions by income group. Results: First, SVM analysis shows that home environment quality and wealth factors show high accuracy in classification and prediction in all three groups. Second, RF analysis shows that estate had the highest predictive power in the high-income group, followed by income, asset, learning, reinforcement, and emotional environment. In the middle-income group, emotional environment showed the highest score, followed by estate, asset, reinforcement, and income. In the low-income group, estate showed the highest score, followed by income, asset, learning, reinforcement, and emotional environment. Conclusion: This study confirmed that home environment quality and wealth factors are significant factors in predicting children's planning-organizing executive functions.

The purpose of this study is to examine the trends of income inequality by gender since 1997 economic crisis and to investigate what is the most influential factor on these changes for males and females. Data used for this study are nine waves of Korean Labor and Income Panel Study(KLIPS). Income inequality is measured by the Gini coefficient and the mean logarithmic deviation(MLD) and the MLDs are decomposed into three components to quantify within- and between-group inequalities. The results show that the extent of income inequality is greater for women during the whole period and is fluctuated more widely. Women's income inequality is mainly affected by the family-related variables, such as age and marital status, while men's inequality is primarily determined by the labor market factors, such as employment status, industrial types and occupation status. These results imply that gender-sensetive welfare policies need to be implemented and that it is necessary to assist the poor women and men through the benefits from the income assistance programs and labor market programs.

The purpose of this study was to investigate levels of self-esteem and related variables among the elderly. The data is from the Korea Welfare Panel Study conducted in 2007. The data was gathered from 2077 elderly, over 65 years old, and was analyzed by Step multiple regression analysis. The major results were as follows. First, the overall level of self-esteem was in the middle range, with an average of 28.18 points. Second, self-esteem levels showed significant differences in terms of gender, age, education level, health, spouse, health insurance, job, monthly household expenses, national pension, assets, home ownership, satisfaction with spouse, satisfaction with leisure, satisfaction with social network, economic services, medical services, and other services. Finally, Model 1 showed meaningful influences from gender, age, education level, health, spouse, and health insurance. Model 2 showed meaningful influences from education level, health, spouse, health insurance, job, and national pension. Models 3 and 4 showed meaningful influences from education level, health, job, satisfaction of spouse, satisfaction with leisure, and satisfaction with social network. In other words, the factors that had the most significant impact on self-esteem were satisfaction.
