This study aimed to verify the reciprocal casual relationship between self-rated health status and depression in the elderly through longitudinal analysis. An autoregressive cross-lagged model was identified. This study analyzed 3,363 elderly people aged 65 or older using the 5th, 6th, and 7th wave data from Korean Longitudinal Study of Ageing(KLoSA). The results are as follows. First, self-rated health status had a positive(+) autoregressive effect. Second, depression had a positive(+) autoregressive effect. Third, self-rated health status had a negative(-) cross-lagged effect on depression, but depression was not a casual predictor of self-rated health status. Based on these findings, it was suggested that there is a need for systematic policies to improve basic fitness in the early stages of old age, as well as the need to expand health promotion programs and implement integrated depression management programs.

This study aims to examine the mutual influences of negative parenting attitudes, self-esteem, and life satisfaction perceived by adolescent children through longitudinal perspective. Data from the first to third years of the panel of the first year middle school students were used among the 2018 data of the Korean Children and Youth Panel Survey (KCYPS) of the Korea Youth Policy Institute. The longitudinal correlation was analyzed by applying the autoregressive cross-lagged model which can determine the direction of longitudinal causality between variables. As a result of the analysis, it was found that the negative parenting attitudes, self-esteem, and life satisfaction perceived by adolescents had a positive effect on the negative parenting attitude perception, self-esteem, and life satisfaction at later times, respectively. In addition, the higher the negative parenting attitude at the previous point was, the lower the self-esteem or life satisfaction afterward. The higher the life satisfaction, the lower the negative parenting attitude of the parents, and the higher the self-esteem. Recognition of negative parenting attitudes of parents lowered the self-esteem of adolescents, whereas the cross-delay coefficient from self-esteem to negative parenting attitude perception was not significant. Through these results, the longitudinal relationship between negative parenting attitude perception of adolescence, self-esteem, and life satisfaction was confirmed and efforts to form positive self-esteem and improve life satisfaction were discussed.

This study explored the longitudinal relationships between school life adjustment and the parents' neglect/abuse as perceived by children according to gender. The participants were 5th and 6th grade children and the instruments were parents' neglect/abuse scale and school life adjustment scale. Using Korea Youth Panel data of Child Youth Policy Institute of Korea, 5th and 6th grade data were analyzed. The results were as follows: Neglect/abuse as perceived by children were different according to their gender and grade. Children who had perceived more parents' neglect/abuse were more likely to have difficulty in school life adjustment. The results of this study suggest that the appropriate interventions for the parents' neglect and abuse is needed by showing the stability of the child's perception of the parents' neglect and abuse during the 5th-6th grade.

This study aims to examine how children's life satisfaction is interrelated with parents' life satisfaction longitudinally. Autoregressive cross-lagged model was employed to analyze the interrelationship between children's and parents' life satisfaction. This study used 6 waves (Elementary school 4th year to Middle school 3rd year) from the Korean Children and Youth Panel Study (KCYPS). The sample size was 1,963 families with child and parent. Key findings are as follows: First, children's and parents' life satisfaction, respectively, was found to influence each other during the study period. Second, parents' life satisfaction were found to have positive and significant cross-lagged impacts on children's life satisfaction. Third, similarly, children's life satisfaction was positively related to parents' life satisfaction longitudinally. The findings suggest that children's and parents' life satisfaction are interrelated in an autoregressive cross-lagged model. This study concludes with implications for enhancing children's and parents' life satisfaction.

The purpose of this study was to provide better understanding of longitudinal effects of early maternal employment on mother-child relationship using 1364 families participating the NICHD Study of Early Child Care in the U.S. Based on the information on maternal employment from 6 months after the child's birth, three employment groups were created: mothers who had always worked more than 30 hours per week, mother who had worked part-time or had been inconsistently employed, and mothers who had never worked. At 36 months, mothers who had extensively employed for the first 36 months showed significantly lower level of supportive presence compared to mothers who had never worked. Mothers who had partly employed for the first year of child's life displayed higher level of supportive presence at 36 months compared to mothers in the other two 12 month employment groups. No other significant employment group differences were found in the mothers' respect for child's autonomy and hostility at 36 months. At first grade, mothers in three employment groups were not different in their relationship with their child. The findings suggested that maternal employment, specifically early extensive maternal employment, does not consistently predict lower quality of mother-child interaction in two or three years later.

This study examined the longitudinal relationship between academic achievement and school satisfaction using a data of the Seoul Panel Study of Children(SPSC). Fully autoregressive cross-lagged analysis and multi-group comparison were performed to measure the longitudinal relationship between two constructs as well as differences between poverty and non-poverty groups. The results showed that both academic achievement and school satisfaction were stable over time in non-poverty group. Academic achievement at the 4th grade significantly affected the school satisfaction at the 6th grade and it subsequently affected on the academic achievement at the 8th grade in non-poverty group. In contrast, academic achievement was not consistent over time in poverty group. Only the school satisfaction at the 6th grade affected the academic achievement at the 8th grade. The findings of this study have various practical implication for school interventions. It is more important to keep supporting the children to maintain the level of academic achievement in non-poverty group. While, in poverty group, it is essential to make school satisfaction and academic motivation increase with school attachment programs.

The purpose of this study is to investigate the change of students' perceptions by comparing factors affecting e-learning intention before and after e-learning experience based on longitudinal data. For this purpose, a research study was conducted targeting university students at Y and K universities in Gyeongsangbuk-do. As a result, first, the convenience of learning time, the ease of learning process, and the usefulness of e-learning had an effect on e-learning intention regardless of the learning experience. Second, the convenience of the learning space was different in the perception before and after the learning experience, and it was found to affect the intention to use after the e-learning experience. Third, college students who have experienced e-learning have shown that the ease of learning process has the most influence on their intention to use. The results of this study can provide an effective direction of e-learning activation and provide basic data for longitudinal research on e-learning learners.

Drawing on third to fifth wave data from the Longitudinal Study of North Korean Migrant Youths' Education, we examined the longitudinal relationship between social capital of North Korean Migrant Youths and school adjustment using latent growth modeling(LGM). Specifically, we sought to answer the following research questions: Do social capital and school adjustment among North Korean Migrant Youths change over time? Is there a relationship between the changes in social capital and school adjustment among these students? Our LGM results showed that trends in social capital and school adjustment among these students were not fixed but changed over time. While the social capital developed by these students was found to influence school adjustment at the time of its development, it did not continue to influence changes in school adjustment over time. Changes in school adjustment of North Korean migrant youths were affected by changes in social capital. These results suggest that there is room for gradual improvement of school adjustment level by strengthening social capital of North Korean migrant youths.

In general, design of urban intersections are fundamentally different from rural intersections, but current urban intersection design has been appled to rural standards. This study has suggested the design standard for urban intersection grades based on the existing literature, field investigating and comparative analysis. Moreover, this study analyzes and compares the differences between urban and rural intersections, and intersections have been derived by appropriate design standards after reviewing the domestic and international grades design criteria. Site survey was performed to validate the derived design criteria by analyzing statistically to establish the design standards. Results were produced for the intersection portion grade standards by comparing the number of instructions which produced appropriate slope degree from 2.5% to 3% in normal condition and slope can be extended to 5% in some critical cases. In-situ investigation was performed to validate the produced data where slope was found from 0.0~8.6%. Additional data of accident analysis were also collected for the validation of the suggested data and correlation analysis was performed using the SPSS tool. Data were analyzed statistically using 95% significance level for vehicle-to-vehicle collided, head-on collision accident rates, where accident rates significantly correlated with the grade. Therefore, appropriate grade at the intersection should be designed and applied in order to reduce the number of accidents at the intersection. Finally, appropriate grades for urban intersections are suggested from 1-3% for normal cases and grades could extend up to 5% for unavoidable cases where extra care must be taken when designing.

The purpose of this study is to verify the causal relationship between social withdrawal and peer alienation among Korean children. The survey study participants were 2,110 children in 2nd, 3rd, 4th, and 5th grades. The 5-year longitudinal data (Korean Child and Youth Panel Survey; KCYPS) of 1st grade elementary school student cohort was used. Latent Growth Modeling was applied to analyze the causality over time of social withdrawal and peer isolation. The results revealed that the trajectories of children's social withdrawal decreased over time. Children's social withdrawal showed significant individual differences in terms of initial value and rates of change. The initial value and slope of children's social withdrawal had an effect on the peer alienation in the 3rd grade; however, there was no significant effect on the peer alienation in the 5th grade.
