The purpose of this research was to delineate the effect of parenting stress of the children's self-esteem. Such variables as the mother's age, her education level and maternal parenting stress were chosen for the analysis. The sample subjects were 659 pairs of fifth/sixth grade of elementary school and first/second grade of middle school and their mothers. The major findings of the research were as follows : First, the children's self-esteem was significantly different to mother's education level but the children's self-esteem not significantly different to mother's age. Second, parenting stress related to temperament, relationship and learning expectation was significantly different to children's self-esteem. Third, the result of stepwise multiple regression analysis on the effects of the maternal variables(mother's age, her education level, parenting stress) to the children's self-esteem indicated that maternal parenting stress related to temperament, relationship and mother education level were the significant contributing factors.

This study examined the effects on preschooler's social competence of preschooler's emotional regulation strategies and maternal attitude toward child's emotional expressiveness. Subjects were 57 3-to 5-year-old preschoolers, their mothers and 3 teachers in their classes. Data were adapted from the Social Intelligence part of Project Spectrum and analyzed by Pearson Correlation Coefficient and Stepwise Multiple Regression Analysis. Findings were that : (1) preschoolers' positive emotion regulation strategies significantly explained their social competence. (2) Older children showed higher social competence than younger children; the effect of children's age on social competence was more influential than emotional strategies or maternal attitudes. In conclusion, preschooler's emotion regulation strategies are an important factor as their social competence develops with age.

This study examined the effects of paternal participation in child care and social support on planning for a second childbirth, focusing on the mediating effect of the mother's parenting stress. The 887 subjects studied in this paper were mothers who have a first child, and were selected from a sample of the 2nd Panel Study of Korean Children(PSKC) by the Korea Institute of Child Care and Education(KICCE), conducted in 2009. Data was analyzed using a Structural Equation Model(SEM) to identify a structure and relationships among factors. The significance of indirect effects to test the mediating effect of maternal parenting stress was identified via bootstrapping. Results indicated that maternal parenting stress partially mediated the relationship between the father's participation in child care and planning for a second childbirth, and absolutely mediated the relationship between social support and planning for a second childbirth. The findings reveal the importance of reducing parenting stress, given its substantial impact on planning for a second childbirth.

Objectives：This study investigated the relationship among child's behavior problems, maternal depression, and parenting stress in children with psychiatric diagnoses and their mothers, and the effect of these variables to the mothers' parenting stress. Methods：Seventy-three children(31 externalizing, 24 internalizing, 18 mixed) and their mothers were involved in this study. The mothers of three groups completed MMPI, KPI-C(Korean Personality Inventory for Children), and PSI(Parenting Stress Index). To investigate the relationships among each variables, ANOVA, Pearson correlation, stepwise regression analysis were performed. Results：There was no significant difference in maternal depression among three groups of children. In 2-Way ANOVA, main effect of maternal depression was statistically significant on depression, parent health, and relationship with spouse subfactor in parent domain, parent domain total, and overall parenting stress. But the main effect of child group was statistically significant on distractability/hyperactivity subfactor in child domain only. In regression analysis, maternal depression explained the parent domain of parenting stress most effectively, and child's hyperactivity and anxiety explained the child domain of parenting stress significantly. Conclusion：These findings suggest that it is important to intervene maternal depression to reduce the parenting stress, along with the treatment of the child's behavior problems.

This study was to examine the role for children's prosocial behavior in terms of maternal parenting behavior, smart-media addiction and ADHD-related behaviors. The study sample was 537 children who had participated in the tenth wave of the Panel Study on Korean Children. The data were analyzed for descriptive statistics, correlation, and serial multiple mediation analysis. The results of this study are as follows. First, it was found that the direct effect of maternal parenting behavior on children's prosocial behavior was not significant. Second, in the relationship between the maternal parenting behavior and the children's prosocial behavior, the mediating effects of smart-media addiction and ADHD-related behaviors were significant, respectively. Third, in the effect of maternal parenting behavior on children's prosocial behavior, it was found that smart-media addiction and ADHD-related behaviors mediate it in series. These results provide to a better understanding of the process between maternal parenting behavior to children's prosocial behavior and especially emphasize the importance of smart-media addiction and ADHD-related behaviors.

Growth traits, such as body weight, directly influence productivity and economic efficiency in the swine industry. In this study, we estimate heritability for body weight traits usinginformation from pedigree and genome-wide single nucleotide polymorphism (SNP) chip data. Four body weight phenotypes were measured in 1,105 $F_2$ progeny from an intercross between Landrace and Jeju native black pigs. All experimental animals were subjected to genotypic analysis using PorcineSNP60K BeadChip platform, and 39,992 autosomal SNP markers filtered by quality control criteria were used to construct genomic relationship matrix for heritability estimation. Restricted maximum likelihood estimates of heritability were obtained using both genomic- and pedigree- relationship matrix in a linear mixed model. The heritability estimates using SNP information were smaller (0.36-0.55) than those which were estimated using pedigree information (0.62-0.97). To investigate effect of common environment, such as maternal effect, on heritability estimation, we included maternal effect as an additional random effect term in the linear mixed model analysis. We detected substantial proportions of phenotypic variance components were explained by maternal effect. And the heritability estimates using both pedigree and SNP information were decreased. Therefore, heritability estimates must be interpreted cautiously when there are obvious common environmental variance components.

This study uses the 1999-2009 Korean Time Use Survey to explore how mothers' employment affects parental time spent in activities that may relate to their children's weight. Specifically, it estimates two-part regression models to assess the effects of maternal employment upon the amount of time mothers spend in activities potentially related to their preschool children's eating and physical activity. The findings suggest that working mothers and those mothers who work longer hours allocate significantly less time in food preparation, eating with the child, and supervising the child's physical activity than mothers who are not employed and those who work fewer hours. The paper also finds that spouses of working mothers do not allocate more time to these activities to offset the reduction in mothers' time. Also, using local unemployment rates as instrumental variables, maternal employment is found to allow mothers to spend significantly more time on food preparation and family meals, although its effect on mothers' total childcare time is negative. Several aspects of Korean society may have made the relationship between maternal employment and childhood weight issues different from what was found in other countries.

Objective: The purpose of this study was to examine the direct and indirect effects of mothers' and children's emotional instability and maternal affectionate-rational parenting on children's attributional style. Methods: The participants of this study were 253 4th, 5th and 6th grade elementary school students and their mothers in Seoul and Incheon. Data were analyzed by path analysis using AMOS 21.0. Results: The results were as follows: First, children's attributional style for negative and positive events was significantly related to children's emotional instability and maternal affectionate-rational parenting. Also, mothers' and children's emotional instability was significantly associated with affectionate-rational parenting. Second, mothers' emotional instability had indirect effects on children's attributional style for negative and positive events through maternal affectionate-rational parenting. Finally, children's emotional instability had not only significant effects on children's attributional style for positive achievement events, but also indirect effects on children's attributional style for negative and positive events through maternal affectionate-rational parenting. Conclusion/Implications: The results of this study suggest that both environmental and individual factors, including mothers'and children's emotional instability and maternal affectionate-rational parenting, need to be considered to explain children's attributional style. Also, these findings have implications for developing intervention programs for children's attributional style and parental education.

This study examined the relationship between maternal attitudes toward children's expressiveness, children's emotional intelligence and problem behaviors. The question as to whether emotional intelligence mediated the relationship between maternal attitudes and problem behaviors was also explored. A sample of 307 preschool children were used as subjects. Mothers rated their levels of acceptance toward their children's emotions, while teachers reported on the children's emotional abilities and behavioral problems. The data were analyzed by means of regression analyses. Our results indicated that mothers' controlling attitudes were associated with low levels of worry-anxiety. Additionally, it was found that children with high emotional intelligence showed low levels of worry-anxiety, hostility-aggression, and hyperactivity-inattention. While multiple factors of emotional intelligence had differential impacts, the self-control factor was the most powerful predictor for all the problem behaviors. It was further found that a mother's receptive attitude was related to higher levels of self-awareness in children. Instead of the significant mediating effect of emotional intelligence, it was revealed that emotional intelligence had greater effects upon problem behaviors than maternal attitudes toward children's expressiveness.

This study investigated the relationship between infants' temperament and mothers' parenting stress. This investigation is done by focusing on the interaction effects between the infants' temperament and maternal factors. A total of 1,120 infants and their mothers from a national sample were selected as subjects for carrying this investigation. The EAS (Emotionality, Activity and Sociality) Temperament Survey for Children: Parental Ratings was used to measure the infants' emotionality temperament, and PSI-SF(Parenting Stress Index-Short Form), KMSS(Kansas Marital Satisfaction Scale) and a survey on socio-demographic variables were used for the maternal factors. Two-way ANOVA revealed that the parenting stress was significantly different according to the infants'emotionality temperament. Most importantly, there were significant interaction effects between the infants' emotionality temperament and maternal factors(education level, employment status and marital satisfaction). The results were discussed in terms of the goodness of fit of the temperament and parenting models.
