The purpose of the present study was to examine mechanisms by which the characteristics of child temperament influences academic achievement in late childhood. It was hypothesized that the effects of child temperament on achievement would be mediated by assertive behavior on the part of children and maternal parenting behavior. Data for this study came from self-report questionnaires completed by 657 elementary school children (343 boys, 314 girls). The results of structural equation modeling demonstrated that child temperament affected academic achievement through both assertive behavior and maternal parenting behavior; this was evidenced across the entire sample. Child temperament (approach-withdrawal, mood quality, persistence) also had a number of positive effects on assertive behavior (directiveness, social assertiveness, defense of rights and interests) and maternal parental behavior (warmth-acceptance, guidance). These results were found to be the case for both boys and girls. The results of this study further revealed that maternal parenting behavior mediated the relationship between child temperament and achievement for boys, whereas assertive behavior played the same role for girls. These findings suggest the need for different approaches in developing programs to improve levels of academic achievement which give due consideration to child temperament and social behavior as well as parenting, based on child gender.

Direct and maternal genetic heritabilities and their correlations with body weight at 5 stages in the life span of purebred Berkshire pigs, from birth to harvest, were estimated to scrutinize body weight development with the records for 5,088 purebred Berkshire pigs in a Korean farm, using the REML based on an animal model. Body weights were measured at birth (Birth), at weaning (Weaning: mean 22.9 d), at the beginning of a performance test (On: mean 72.7 d), at the end of a performance test (Off: mean 152.4 d), and at harvest (Finish: mean 174.3 d). Ordinary polynomials and Legendre with order 1, 2, and 3 were adopted to adjust body weight with age in the multivariate animal models. Legendre with order 3 fitted best concerning prediction error deviation (PED) and yielded the lowest AIC for multivariate analysis of longitudinal body weights. Direct genetic correlations between body weight at Birth and body weight at Weaning, On, Off, and Finish were 0.48, 0.36, 0.10, and 0.10, respectively. The estimated maternal genetic correlations of body weight at Finish with body weight at Birth, Weaning, On, and Off were 0.39, 0.49, 0.65, and 0.90, respectively. Direct genetic heritabilities progressively increased from birth to harvest and were 0.09, 0.11, 0.20, 0.31, and 0.43 for body weight at Birth, Weaning, On, Off, and Finish, respectively. Maternal genetic heritabilities generally decreased and were 0.26, 0.34, 0.15, 0.10, and 0.10 for body weight at Birth, Weaning, On, Off, and Finish, respectively. As pigs age, maternal genetic effects on growth are reduced and pigs begin to rely more on the expression of their own genes. Although maternal genetic effects on body weight may not be large, they are sustained through life.

The postpartum is a period of transition to motherhood where a childless woman transforms into a woman with children. Parents, especially mothers must perform an essential role of implementing instrumental and emotional care behaviors on part of the helpless, dependent, and immature infant. First-time mothers, however, suddenly face the responsibility of round the clock duty without neither parenting training during pregnancy, nor a time to gradually adapt to growing responsibilities after birth, with confusion and frustration as a result. Thus, after providing first-time mothers with childcare education as maternal role preparation, this study will try to examine its effects on childcare behaviors and confidence in maternal role during the early postpartum period. This quasi-experimental study using a nonequivalent control group non-synchronized design, was carried out from March 1995 to May 1996 to verify the effects of a childcare education program with first-time mothers who had vaginal delivery in Ewha University Hospital, Seoul, Korea, and collected data from 60 subjects who consented to the study. The education was given in the early postpartum period(48-72 hours after delivery) and to measure its effects, a posttest was done 4 weeks later with the results analyzed by SPSS shown in the following : 1. The childcare behavior score of the experimental group that had received the newborn care education was higher than the control group(t=3.5, P=.001). 2. The control group and the experimental group which had received the education showed no difference in degree of confidence in maternal role. 3. The higher the childcare behavior score, the higher the degree of confidence in maternal role was among the subjects(r=.56, P=.001). The preceding results are significant in that childcare practices can be promoted by providing child-care education to first-time mothers in the early postpartum period. Thus, this education can be used as a nursing intervention strategy in the early postpartum period.

This study examined the impact of academic achievement and maternal differential treatment on academic self-concept among adolescent siblings. The sample consisted of 438 students attending middle schools in Seoul (M = 15.2 yrs.), who had a sibling. Data were analyzed using Structural Equation Modeling. Academic achievement compared with a sibling and maternal differential treatment had direct effects on academic self-concept, indicating that children with higher academic achievement scores than their sibling and with perceived maternal differential treatment reported a significantly higher academic self-concept. Also, the relationship between academic achievement as compared with a sibling and academic self-concept was mediated by maternal differential treatment. These findings could be used in educational settings as a basis for improving the academic self-concept of early adolescents.

Objective: This study examined the relationship between maternal beliefs on social development, management strategies of peer relations, and their child's peer competence in order to understand how to promote children's peer competence. Methods: Self-report questionnaires were used on 195 mothers with children four to years old. Data were analyzed using Pearson Correlation Analysis and Baron and Kenny's three-step regression. Results: First, there was a positive relationship between maternal beliefs on social development and their child's peer competence. Second, this study found that there were partial mediating effects of advice·support and supervision on the relationship between maternal beliefs on social development and children's social competence. Conclusion/Implications: The findings confirm that mothers' beliefs on social development and management strategies of peer relationships are proceeding factors for children's peer competence. Significant attention should be paid to mothers' beliefs on social development and management strategies of peer relationships for children's positive social development.

The purpose of this research is to study the causal model among mother related variables, child abuse, and children's emotional maladjustment behaviors. The sample subjects were 542 pairs of fifth and sixth grade elementary school students and first as well as eighth grade middle school students, and their mothers. The major findings of the research are as follows: First, the result of multiple regression analysis on the effects of the maternal parenting stress and marital satisfaction to the children's abuse indicates that stress related to learning expectation and stress related to relationship with child are the significant contributing factor to physical abuse and verbal abuse. Second, the result of multiple regression analysis on the effects of the maternal parenting stress and child abuse to the children's emotional maladjustment behaviors indicate that verbal abuse is the significant contributing factor. Third, looking at causal relations of the maternal variables (maternal parenting stress, marital satisfaction) and child abuse (physical abuse, verbal abuse, neglect) to the children's emotional maladjustment behaviors, maternal variables impact indirectly through the child abuse factor.

The study examined the pathways from maternal reactions to children's negative emotions to children's emotion intelligence through children's resilience by gender. The participants in this study comprised 413 elementary school 4th-6th graders (of which 214 were boys, and 199 were girls). They completed questionnaires on maternal reactions to children's negative emotions, children's resilience and levels of children's emotional intelligence. Data were analyzed by means of T-test and structural equation modeling. In the case of the male group, it was found that maternal emotion coaching, when done indirectly, but not directly, had an influence on their levels of emotional intelligence. On the other hand, in the case of the female group, it was found that emotion coaching, when done indirectly, as well as directly, had an influence on their levels of emotional intelligence. Therefore, these results indicate that children's resilience mediated the effects of maternal emotion coaching on emotional intelligence. It also found that there are distinct pathways from maternal reactions to children's negative emotions to emotion intelligence through resilience by gender.

The purpose of this study was to examine the effects of maternal rejective parenting behaviors and preschoolers' aggression and social skills on preschoolers' exclusion by peers. Subjects were 91 5- to 6-year-old preschoolers(49 boys, 42 girls) and their mothers. Data was analyzed by descriptive statistics, correlation analysis and stepwised multiple regression analysis. The major findings are summarized as follows: (1) preschoolers' exclusion by peers was positively correlated with maternal rejective parenting behaviors and preschoolers' aggression. On the other hand, preschoolers' exclusion by peers was negatively correlated with preschoolers' social skills. (2) The most influential factor on preschoolers' exclusion by peers was preschoolers' cooperative behaviors, and the next influential factor on preschoolers' exclusion by peers was maternal rejective parenting behaviors. In conclusion, maternal rejective parenting behaviors and preschoolers' social skills influence preschoolers' exclusion by peers.

This study examined the mediating effect of self-esteem in the relationship between maternal rejective parenting attitude and children's leadership as well as identified gender differences in the mediating pathways. The mediating effects of this study were examined after controlling the effect of maternal employment status on rejection parenting attitude and the effect of siblings on the children's leadership. Participants consisted of 330 five- and six-year-old children (151 boys and 179 girls) and their mothers. Data analyses included t-tests, F tests, $Scheff{\acute{e}}$ post-hoc tests and Pearson's correlation. Structure equation modeling examined the mediating effect of self-esteem. Bootstrapping method was applied to examine the significance of the mediating effects. Gender differences in the mediating effect were examined through multiple group path analyses. The results of this study were as follows. First, self-esteem mediated the relationship between the maternal rejective parenting attitude on children's leadership. Second, there was a significant gender difference in the mediating pathways with a full mediating effect of self-esteem for boys; however, there was only a partial mediating effect for the girls. This study has implication for investigating gender difference in the mediating mechanism of explaining variance in the leadership of preschoolers. The limitations and more implications of this study are also discussed.

This study examines the effects of maternal behaviors and children's self-control ability on their subjective well-being. Data were collected from 416 fifth- and sixth-graders residing in Kwangju, Korea. Cronbach's ${\alpha}$ and the hierarchical regression analysis method were employed for a statistical analysis. According to the results of the hierarchical multiple regression analysis, children's self-control ability best explained their subjective well-being. For individual factors, motivational self-control had the greatest effect on subjective well-being, followed by behavioral self-control, cognitive self-control, the level of income, gender, and the employment status, in that order. The results for effects of maternal behaviors and children's self-control ability on children's subjective well-being highlight. The important roles played by the mother and the child's self-control ability in improving the child's subjective well-being. The study contributes to the literature by providing fundamental insights into children's higher quality of life.
