The purpose of this study is to identify changing patterns in multicultural adolescent's life satisfaction and to explore longitudinal changes in the effects of acculturation stress, self-esteem and family support on the changes in life satisfaction. For this purpose, the survey data from the 4th to 6th years of the Multicultural Youth Panel Survey were used for the analysis. As a result of the analysis, life satisfaction, self-esteem, and family support decreased for 3 years through each linear change model. As a result of examining the longitudinal mediating effects of self-esteem and family support between acculturation stress and life satisfaction through the multivariate potential growth model, the mediating effect of self-esteem and family support was confirmed. Based on these results, practical implications for improving life satisfaction, self-esteem, and family support of multicultural youth were presented.

Background: This study purposed to compare the difference on medical utilization and health expenditure of baby boomer generation by depression between gender. Methods: Korea Welfare Panel Survey 2016, provided by the Korea Institute for Health and Social Affairs, was used for the analysis. For the research, we used the two-part model, yes or no of use (part 1), and frequency of use (part 2) for medical utilization. The dependent variables are the whether or not to use of hospitalization services, outpatient services, length of stay, outpatient service visits, and health expenditure. And the independent variables are used as the predisposing (education, spouse presence), enabling (insurance type, private insurance, economic activity, income), and need (chronic disease, self-rated health, disability) factors in the Andersen behavior model. Depression was used as intervening variables. Structural equation model and multiple group analysis by gender were used. Results: There were differences in the medical care usage and cost between men and women in baby boomer. For men, mediating effects of depression were present at the hospitalization (yes/no), length of stay, and health expenditure. On the other hand, for women, the mediating effect of depression was found only at the outpatient visits. Specially, depression was working at the medical services by the different way between gender. The size of effect (multiple group analysis) was affected by significant differences between men and women. Conclusion: This study found that the mediating effect of depression is increased medical usage and health expenditure and the effect factors are different by gender. Therefore, it is necessary to establish a medical care policy considering the socio-economic characteristics of baby boomers.

This study aimed to examine the associations between family economic status, social relationships, and the career identity of adolescents. The study assessed the mediating effects of social relationships on the relationship between economic status and the career identity of adolescents, utilizing data from the Korean Children and Youth Panel Survey (KCYPS). The result indicated that family economic status was related to the quality of the social relationships that significantly affected the career identity of adolescents. These findings suggested that the inequality in career development of adolescents due to family economic status could be reduced by promoting positive social relationships. Convergent interventions that help adolescents to build positive social relationships would be necessary to improve the career outcomes of those from low-income families.

Purpose The purpose of this study is to develop a prediction model and decision rules for the elderly's suicidal ideation based on the Korean Welfare Panel survey data. By utilizing this data, we obtained many decision rules to predict the elderly's suicide ideation. Design/methodology/approach This study used classification analysis to derive decision rules to predict on the basis of decision tree technique. Weka 3.8 is used as the data mining tool in this study. The decision tree algorithm uses J48, also known as C4.5. In addition, 66.6% of the total data was divided into learning data and verification data. We considered all possible variables based on previous studies in predicting suicidal ideation of the elderly. Finally, 99 variables including the target variable were used. Classification analysis was performed by introducing sampling technique through backward elimination and data balancing. Findings As a result, there were significant differences between the data sets. The selected data sets have different, various decision tree and several rules. Based on the decision tree method, we derived the rules for suicide prevention. The decision tree derives not only the rules for the suicidal ideation of the depressed group, but also the rules for the suicidal ideation of the non-depressed group. In addition, in developing the predictive model, the problem of over-fitting due to the data imbalance phenomenon was directly identified through the application of data balancing. We could conclude that it is necessary to balance the data on the target variables in order to perform the correct classification analysis without over-fitting. In addition, although data balancing is applied, it is shown that performance is not inferior in prediction rate when compared with a biased prediction model.

The purpose of this study was to improve children's positive perceptions of the future by examining the relationship between parental attachment, parental involvement in learning, and children's perceptions of the future, and by identifying the specific influence of each variable on children's perceptions of the future. Frequency analysis and descriptive statistical analysis were performed on data from the 12th year of the Korean Children's Panel (2019), and Pearson's moment correlation coefficient was calculated for correlation analysis between variables. Multiple regression analysis was performed to examine the explanatory power of parental attachment to children's perception of the future and parental participation in learning. The research results are as follows. First, the correlations among all the latent variables of parental attachment, parental participation in learning, and children's future perception showed significant correlations. Second, the explanatory power of children's perception of the future was found in the order of 'mother' trust, 'family'-based participation, 'father' trust, and 'mother' communication. These results suggested that parental trust and warm, warm participation in home-based learning were important variables in children's positive perception of the future.

The purpose of this study was to examine the relationship among children's perceived parental attachment, parental happiness, and children's autonomy, and to find out in detail the influence of parental attachment and parental happiness on children's autonomy. Frequency analysis and descriptive statistical analysis were performed on data from the 12th year of the Korean Children's Panel (2019), and Pearson's moment correlation coefficient was calculated for correlation analysis between variables. Multiple regression analysis was conducted to examine the influence of parental attachment and parental happiness on children's autonomy. The research results were as follows. First, parental attachment perceived by children, parental happiness, and children's autonomy were all positively correlated. Second, among the sub-variables of parental attachment, maternal trust, paternal trust, and maternal communication were found to have an influence, and only maternal happiness was found to have an effect on parental happiness. This means that parental attachment acts as a more important variable than parental happiness. Therefore, we need constant attention and effort to support children in a more intimate and stable relationship with their parents so that they can gain life satisfaction through active and proactive choices and decisions.
