This study was performed to identify the predictability of maternal authority from the perspective of children's social competence and mothers' control behavior. The subjects of this study were 369 children from an elementary school in Mokpo. The results were as follows: 1) There were relationships among children's social competence and maternal control behavior and authority. 2) Children's social competence was explained by the maternal control behavior. Maternal imperative control nagatively effected the sociability among children's social competence. Maternal position control positively effected all the children's social competence. 3) Children's social competence was explained by the maternal authority. All maternal control types changed when maternal authority was included. The change of children's social competence was related due to maternal control plus maternal authority. This result illustrates that maternal authority exhibited a powerful effect on children's social competence.

This study looked into estimation of variance component over swine's economic traits by multiple animal model and maternal effect model using on-farm test data of total 31,455 swine of Duroc, Landrace and Yorkshire species that were born between 2000 and 2008. Heritability by estimated additive genetic effect showed higher than one by maternal genetic effect using multivariate maternal animal model in each trait examined by each breed and most heritability when considering only additive genetic effect in multiple traits animal model was estimated to be higher than one by estimated additive genetic effect in multivariate maternal animal model. In correlation between breeding value by estimated maternal genetic effect and phenotypic value using multivariate maternal animal model, rank correlation and simple correlation of breeding value and phenotypic value by maternal genetic effect also showed low positive correlation or strong negative correlation, which can be considered that if correlation with phenotype were increased properly considering maternal genetic effect in each trait by each breed, even better improvement could be promoted.

Objectives: The purpose of this study was to examine the effect of children's values, parent-child interaction, family cohesion and flexibility on paternal and maternal warmth and control parenting. Method: The sample used in this study included 806 parents of boys and 748 of girls who were first married couples and living together in the 6th wave of the Panel Study on Korean Children(PSKC). Hierarchical regression analyses were used to identify the effect of predictable variances on paternal and maternal parenting. Results: Variables found to have a statistically significant effect on parenting differed in terms of warmth and control parenting. Fathers who engaged in playing with their children were found to have a strong effect on paternal warmth parenting, whereas participation in children's activities has the strongest effect on maternal warmth parenting. Conclusions: This study suggested that there were differences in paternal and maternal warmth and control parenting according to the gender of the child. Further implications were discussed for exploring maternal and paternal parenting of young children.

Stored maternal factors in oocytes regulate oocyte differentiation into embryos during early embryonic development. Before zygotic gene activation (ZGA), these early embryos are mainly dependent on maternal factors for survival, such as macromolecules and subcellular organelles in oocytes. The genes encoding these essential maternal products are referred to as maternal effect genes (MEGs). MEGs accumulate maternal factors during oogenesis and enable ZGA, progression of early embryo development, and the initial establishment of embryonic cell lineages. Disruption of MEGs results in defective embryogenesis. Despite their important functions, only a few mammalian MEGs have been identified. In this review we summarize the roles of known MEGs in mouse fertility, with a particular emphasis on oocytes and early embryonic development. An increased knowledge of the working mechanism of MEGs could ultimately provide a means to regulate oocyte maturation and subsequent early embryonic development.

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.

Objectives The loss of maternal care during early postnatal period may increase development of mood-related disorders, such as depression, anxiety, and personality disorders. In this study, the effect of acupuncture on depression in relation with cell proliferation in the hippocampal gyrus dentatus was investigated using maternal-separated rat pups. Methods On the postnatal 14th day, rat pups from six dams were grouped into following groups: maternal care group, maternal separation group, maternal separation and non-acupoint-acupunctured group, maternal separation and Zusanli-acupunctured group, and maternal separation and fluoxetine-treated group. Acupuncture was performed from postnatal 28th day to postnatal 37th day. The rat pups that belong in the maternal separation and fluoxetine-treated group were injected subcutaneously with 5 mg/kg fluoxetine hydrochloride once a day for the same period of time. To evaluate activity of the rat pups, open field test was performed. Immunohistochemistry for serotonin (5-hydroxytryptamine, 5-HT) and tryptophan hydroxylase (TPH) in the dorsal raphe and for 5-bromo-2'-deoxyuridine (BrdU) in the hippocampal gyrus dentatus was conducted. Results The present results reveal that the activity was decreased by maternal separation. In contrast, acupuncture at Zusanli overcame maternal separation-induced hypoactivity. Maternal separation suppressed TPH expression and 5-HT synthesis in the dorsal raphe and decreased cell proliferation in the hippocampal gyrus dentatus of rat pups. In contrast, acupuncture at Zusanli alleviated maternal separation-induced decrease of 5-HT synthesisand TPH expression. Conclusions The present results demonstrate that acupuncture at Zusanli ameliorated depressive state through increasing cell proliferation and enhancing 5-HT synthesis.

This study considered the problem of whether the method of Lamaze education changes maternal attitudes toward childrearing, material-infant interaction and is feasible for Korean culture in nineteen mother. infant dyads. Among those mothers, nine were assigned experimental group who received Lamaze education at the period of 7th and 8th month of gestation, and ten were assigned control group who received obstetric routine care. Maternal attitudes were assessed with selected items from Cohler's Maternal Atttiude Scale. Maternal Play Interaction Scale was used during play session to evaluate maternal sensitivity, infant response and mother-infant dyadic synchrony. There were no significant differences not only between the two groups, but also between the period of pre-lamaze education and post-delivery on the Cohler's maternal attitude scale. Experimental mothers and babies scored significantly higher on maternal sensitivity and infant response. But no differences in mother-infant, dyadic synchrony were found. This findings mean that the effect of the lamaza education on the maternal attitudinal change related to be needed the change of cognitive structure is delayed while the effect of that on the maternal infant behavioral response showed immediatly. Modification of Lamaze method is necessary for practical use in our sociocultural system.

Objective: The purpose of this study is to confirm the structural relationship among maternal parenting stress, neglectful mediation of smart media and the over use of smart media in preschool children. Methods: Quantitative surveys were conducted to measure maternal parenting stress, smart media neglect mediation, and over use of smart media in preschool children. In addition, the mediating effect of maternal neglectful smart media mediation in maternal parenting stress and preschool children's over use of smart media was verified using the Amos 23.0 and SPSS 26.0 programs Results: Maternal parenting stress and mother's neglectful mediation of smart media had a direct effect on preschool children's over use of smart media. In addition, mother's neglectful mediation of smart media mediated the influence of the mother's parenting stress on preschooler children's over use of smart media. Conclusion/Implications: These findings emphasize the important role of maternal stress in preschool children's over use of smart media. And maternal competence such as supervision and limit setting is an important role in preschool children's use of smart media, so it is necessary to develop a practical and diverse parenting education program in order to reduce.

Objective: Studies have revealed that parenting is a crucial factor for children's effortful control and externalizing behaviors, however, less is known about the underlying mechanism that may be moderated by maternal depression. Therefore, the present study is aimed to testify the mediating effect of children's effortful control and moderating effect of maternal depression in the association between parenting(i.e. limit setting, overprotective/permissive parenting) and children's externalizing behaviors. Methods: Three hundred and one mothers with 4 to 6 years old children reported their parenting behaviors, depression, their children's effortful control and externalizing behaviors. Data were analyzed using SPSS and Process Macro. Results: Results showed that children's effortful control mediated the association between parenting and children's externalizing behaviors and maternal depression moderated the association between parenting behaviors and children's effortful control as well as between parenting behaviors and children's externalizing behaviors. The moderated mediation effects were stronger among mothers with lower levels of depression. Conclusion/Implications: These findings could contribute to a better understanding of how and when maternal limit setting and overprotective/permissive parenting impact children's externalizing behaviors. It is suggested that future efforts to provide the parenting intervention take a target specific approach (e.g. considering mother's depression symptom), on order to maximize the effectiveness of program to ultimately facilitate children's positive adjustment.

Objectives : The aim of this study was to examine the effects of maternal sociodemographic characteristics, especially education and employment, and parenting stress on the child's self-concept. Attention was also paid to the mediating impact of parenting style on the relationship between the maternal variables and a child's self-concept. Methods : A questionnaire and three scales were completed by fifth graders and their mothers, and 270 sets of paired data were analyzed. Results : The results showed that mothers with higher education experienced less child-related parenting stress, were perceived to be more achievement-oriented and rational by their children, and also had children with more positive self-concept. The relationship between maternal education and child's self-concept was mediated by the rationality dimension of parenting style. Maternal employment was not related to parenting stress, parenting style and most aspects of the child's self-concept. Lastly, child-related parenting stress had a negative effect on the child's self-concept, and this effect was mediated by the warmth and rationality dimensions of parenting style. Conclusion : Parenting style had a mediating effect on the relationships between the child's self-concept and maternal education and child-related parenting stress.
