The purpose of this study was to find pathways among factors that distinguish the mothers' intention to have a second child. As for factors affecting the childbirth intention of mothers, this study aimed to explore pathways from fathers' participation in childrearing to intention of second childbirth as mediating variables, maternal parenting stress and marital satisfaction. This study used the third wave data of the Panel Study of Korean Children (PSKC) that is a national-representative birth-cohort study. Among the 1,802 participants of the PSKC, 717 mothers who have a husband/partner and only one child have responded a decided intention of second childbirth. SPSS 19.0 and Amos 19.0 were used to implement exploratory analyses of predictors and test path models. Results showed that the hypothetical model assuming a path from paternal involvement in childrearing to mothers' intention of second childbirth, mediated by maternal parenting stress and marital satisfaction fitted the data of working mothers and non-working mothers well. The results suggest policies focusing on internal characteristics of mothers and dynamics in the family.

Objectives: The study examined the mediated role of family functioning in the relation between fathers' and mothers' depression and drinking behaviors, and children's internalizing/externalizing problems and peer-play behavior. Methods: The study utilized data from the Panel Study on Korean Children(PSKC), namely Wave 5 data(N=1,703) for parental depression and drinking behavior, Wave 6 data(N=1,662) for family functioning, and Wave 7 data(N=1,620) for children's internalizing/externalizing problems and peer-play behavior. Results: Mothers' perceived family functioning mediated the relation between parental depression and boys' internalizing/externalizing problems. Second, fathers' perceived family functioning mediated the relation between parental depression and children's peer-play behavior. Third, only when both parents engaged in an above-average level of drinking behavior, did father perceive that their family functioning was low. Conclusions: This study showed the mediated effect of family functioning in the influence of parental depression and drinking behavior on children's developmental outcomes. The study ditermined that fathers and mothers played different roles in children's development, and found different mechanisms related to parental depression and their drinking behavior.

Objective: This study was conducted to examine the significant factors affecting media device addiction using the data mining technique for large-scale data from the Panel Study on Korean Children Survey (PSKC). The PSKC data of this study were gathered from the elementary school students in their 10th survey (1,286 3rd grade students). Methods: The SPSS 21.0 program was used for data mining decision tree analysis, and the results are as follows. Results: First, the most important predictor of media device addiction was planning-organization which was among the sub-factors of executive function. Second, as a result of the decision tree analysis, the children with the highest probability of addiction to media devices were ones that had difficulties in planning and organizing, had mothers with a permissive parenting attitude felt difficulties in controlling behavior, and were alone at home for more than two hours a day without any adult supervision. Conclusion/Implications: The results of this study can help guide the direction of future research related to children's addiction to media devices by exploring and analyzing factors that significantly affect children's addiction to media devices.

The purpose of this study was to examine the effect of parent-child interactions on children's academic performance focusing on the mediating effect of children's executive function difficulty. The data for this study were drawn from the Panel Study on Korean Children(PSKC). The participants were 559 children of elementary school and their families from 8th wave(1^st graders), 9th wave(2^nd graders), and 10th wave(3^rd graders) of PSKC. The data were analyzed with structural equation modeling. The results of this study were as follows. First, mother-child interaction and father-child interaction didn't have a significant direct effect on children's academic performance. Second, mother-child interaction had a significant positive indirect influences on academic performance through children's executive function difficulty. The results of this study indicated that mother-child interaction and children's executive function difficulty are important for children's academic performance.

This study examined whether there are underlying latent classes of growth trajectories of maternal depression in the Korean population. Data from the first phase of the Panel Study of Korean Children (PSKC) of the Institute of Child Care and Education (KICCE) were used for this study. The final sample of participants included 1,471 mothers, who completed three interviews: at birth, at one month, and at four months. A two-class model consisting of depression (12.3%) and non-depression (87.7%) was considered the best-fitting solution using Mplus 3.13. The changes in postnatal depression in the Korean population within four weeks after childbirth, which is the period of "postpartum onset", seem to be important. Logistic regression analysis showed that duration of breast-feeding and planned pregnancy effects were significantly associated with trajectory class membership.

This study examined the causal relationships between parenting stress and self-efficacy of Korean mothers with an infant according to employment status using the second through fourth wave data of the Panel Study of Korean Children (PSKC). Autoregressive cross-lagged modeling was performed to test the longitudinal reciprocal relationships between the two constructs. Our results indicated that both maternal parenting stress and self-efficacy were consistent over time. The results also indicated that there was a significant cross-lagged effect of maternal parenting stress on their self-efficacy, rather than vice versa. No differences between working and non-working mothers were found in the relationship between the two constructs.

The main purpose of this study was to investigate the paths from the cumulative risk factors to infant's development at 24 months of age via the mediation of maternal parenting behaviors. The data consisted of 3 year's worth of data harvested from 1802 families participating in the Panel Study on Korean Children (PSKC). The results revealed that cumulative family risk factors tended to stay in the family in relatively stable ways. Early risk factors significantly predicted later risk factors. Cumulative risk factors were negatively associated with the parenting styles of mothers, which in turn, significantly predicted the development of the infants concerned. Statistical tests supported the notion that mothers' parenting behavior is the mediator of the relation between family risk factors and infant's developmental outcomes.

The current study examined the effects of early social support of first-time mothers on the home environment for their preschool-aged children via the mediation of mothers' depression. The study sample included 755 first-time mothers participating in the Panel Study on Korean Children(PSKC). Using Structural Equation Modeling(SEM), the longitudinal structure from mothers' social support when the child is one year old to the quality of the home environment when the child is 4 years old was examined. The results revealed that mothers' social support at age 1 predicted social support at age 3, which in turn predicted higher quality of the home environment for their children at age 4. The mediation of depression was also significant. Mothers' social support predicted lower levels of depression at both phases and mothers' depression was significantly associated with the quality of the home environment.

The purpose of the study was to examine the effects of family related factors (mothers' self-esteem, mothers' parenting stress, mothers' marital satisfaction, fathers' parenting involvement, and social support) on mothers' postpartum depression. The subjects were 797 households that were extracted from the $1^{st}$ wave of the Panel Study of Korean Children (PSKC). The study variables were measured using the survey questionnaires, and analyses of Pearson's correlation and multiple regression were conducted. Results showed that family related factors significantly predicted mothers' postpartum depression. Moreover, the most significant predictor was mothers' parenting stress, followed by marital satisfaction, self-esteem, fathers' parenting involvement, and social support. Study findings indicate that mothers' postpartum depression is attributed to not only personal but also family related factors. Our results suggest importance of parent education and family support along with social support.

The purpose of the study was to examine the effects of preschool teachers' qualification (education level, teaching experience, major, and certification) and competency variables (teaching efficacy and teacher-child interaction) on young children's development (cognition, language, and social development). The data came from $5^{th}$ Wave of Panel Study on Korean Children (PSKC) from the Korea Institute of Child Care and Education, and the multiple regression analyses as well as Pearson's correlation analyses were used. The results showed the positive associations between teachers' competency (teaching efficacy and teacher-child interaction) and child development. However, we did not find significant effects of teachers' qualification on young children's development. Based on the results, we proposed a policy implication that teacher qualification needed to be discussed with teacher competency to improve teacher quality.
