The purpose of this study was to compare parenting stress between mothers who have young children with and without disabilities. The subjects of this study were 100 mothers who take care of disabled children and 123 mothers who take care of non-disabled children. The children's ages were from 3 to 6 years. The results of this study were as follows; First, the mothers who have disabled children have more parenting stress than those who have ordinary children. Second, the mothers who have developmentally disabled children had more parenting stress than mothers who had other disabled children. Children's and mothers' ages had an influence on the parenting stress of the ordinary mothers. The mothers who had children with and without disabilities got less parenting stress as the mothers received more higher parenting efficacy, parent role satisfaction, marital satisfaction and family support.

Have elderly parents parted with parental role after the children were grown up? If they still have, what kinds and degrees of parental responsibilities endured? Do they actively perform the role? Do they satisfy to engage in parenting? The main purpose of present study explored these questions conceming rural old-aged families using data of 143 elderly parents aged 60 years and above. The results indicate that elderly parents perceived parenting adult children to be very important, regarding themselves as househeads to teach family members how to integrate together. The results also demonstrate that elderly parents performed parental role actively in teaching family rituals and providing emotional support. The elderly parents also report that they were fairly satisfied with involvement in adult children's lives. Our findings suggest that further in-depth research is required in eliciting the role parameters of elderly parents based on our social and cultural changes. In addition, it is encouraged to examine the adult children's expectation of their elderly parents for renegotiating and restructuring parent-child relationships when both are adults.

The purpose of this study was to investigate the effects of Mother's anger and depression on young children's problem behaviors. Data collection was from May 1, to July 1, 2019, and 244 Mother's entrusted infants and young children to three early childhood education institutions in Daejeon, Busan and Ulasn. The collected data were analyzed using descriptive statistics, t-test, ANOVA, Pearson correlation coefficient, and multiple liner regression analysis using SPSS/WIN 24.0. The results of this study showed that the young children's problem behavior had a statistically significant positive correlation with Mother's anger(r=.261, p=<.001), and depression(r=.435, p<.001). The multiple regression analysis showed that the factors that significantly affect the young children's problem behavior were depression(𝛽=16.57, p<.001) of the Mother's and the total explanatory power was 19.2%. Therefore, it provided implication for the need to develop parent education program to support the reduction of depression factors along with the emotional support Mother's.

Pumasi and Cooperative Child Care Sharing have had positive results among participants and show possibilities of spreading out to the community in general. However, performance was not proved where it is clarified, and the experience of 23 local Healthy Family Support Centers have that ran the demonstration project were unable to be collected. It is the point of time when the initial backing up is important but the centers do not have the systematic support. Therefore, this research presents an effective management plan through qualitative research involving Pumasi participants and person in charge. The operation strategies by the stage of the project were as follows: First, in the beginning stage, the person in charge establishes the target and vision of the project. Second, when comprising the Pumasi team, it was necessary to consider their characteristics according to the team organization subjects. Third, it is necessary to extend the turn-off time and provide many programs so that the various populations can participate. Fourth, in the advertising step, word of mouth and individual contact needs to be utilized. Fifth, in a medium or small city or an urban-rural complex area, the person in charge should support the participants' Pumasi activities. Sixth, various programs such as a passive and active parent education program and Pumasi education program for the leader needs to be provided for the activation of Pumasi activities. Lastly, a cooperative child care sharing location needs to be constructed by the duality system of the base space and outer space. In this location, the inside play space for the children is essential.

This study is to examine the mediating effects of parenting efficacy the relation between the self-esteem and child career support behavior(encourage, meddle, non-involvement) of mothers of multicultural families. To this end, data from the 7th year's multicultural youth-parent panel were used, and descriptive statistics, correlation analysis, and regression analysis were conducted on the data of 1,188 married immigrant women. The result of the analysis showed that self-esteem (β=.277) and parental efficacy (β=.134) were positively significant as factors affecting the child career support behavior of mothers of multicultural families. In addition, parental efficacy was found to provide partial mediation in the relationship between self-esteem and child career support behavior. Based on this, this study suggested policy and practical measures to improve parental efficacy of mothers of multicultural families and to conduct desirable child career guidance.

The regulation of neurotoxicants has usually been based upon setting reference doses by dividing a no observed adverse effect level (NOAEL) by uncertainty factors that theoretically account for interspecies and intraspecies extraploation of experimental results in animals to humans. Recently, we have proposed a four-step alternative procedure which provides quantitative estimates of risk as a function of dose. The first step is to establish a mathematical relationship between a biological effect or biomarker and the dose of chemical administered. The second step is to determine the distribution (variability) of individual measurements of biological effects or their biomarkers about the dose response curve. The third step is to define an adverse or abnormal level of a biological effect or biomarker in an untreated population. The fourth and final step is to combine the information from the first three steps to estimate the risk (proportion of individuals exceeding on adverse or abnormal level of a biological effect or biomarker) as a function of dose. The primary purpose of this report is to enhance the certainty of the first step of this procedure by improving our understanding of the relationship between a biomarker and dose of administered chemical. Several factors which need to be considered include: 1) the pharmacokinetics of the parent chemical, 2) the target tissue concentrations of the parent chemical or its bioactivated proximate toxicant, 3) the uptake kinetics of the parent chemical or metabolite into the target cell(s) and/or membrane interactions, and 4) the interaction of the chemical or metabolite with presumed receptor site(s). Because these theoretical factors each contain a saturable step due to definitive amounts of required enzyme, reuptake or receptor site(s), a nonlinear, saturable dose-response curve would be predicted. In order to exemplify this process, effects of the neurotoxicant, methlenedioxymethamphetamine (MDMA), were reviewed and analyzed. Our results and those of others indicate that: 1) peak concentrations of MDMA and metabolites are ochieved in rat brain by 30 min and are negligible by 24 hr, 2) a metabolite of MDMA is probably responsible for its neurotoxic effects, and 3) pretreatment with monoamine uptake blockers prevents MDMA neurotoxicity. When data generated from rats administerde MDMA were plotted as bilolgical effect (decreases in hippocampal serotonin concentrations) versus dose, a saturation curve best described the observed relationship. These results support the hypothesis that at least one saturable step is involved in MDMA neurotoxicity. We conclude that the mathematical relationship between biological effect and dose of MDMA, the first step of our quantitative neurotoxicity risk assessment procedure, should reflect this biological model information generated from the whole of the dose-response curve.

Objective: The present study aimed to investigate the sequential mediation effects of creative home environment and preschoolers' playfulness on the relationship between mothers' play beliefs and preschoolers' happiness. Methods: The subjects of this study were 233 preschoolers between the ages of 3 and 5 and their mothers. Mothers were asked to complete a questionnaire that assessed their beliefs about play, the creative home environment they provided, as well as their child's playfulness and happiness. The data collected were analyzed using the SPSS Process Macro program to investigate the sequential mediating effects. Results: The study found that the mothers' play support beliefs were directly associated with their preschoolers' happiness. Additionally, the creative home environment was found to mediate the relationship between the mother's play beliefs and their preschooler's happiness. The children's playfulness was also identified as a mediator in the relationship between the mother's play beliefs and their preschooler's happiness. Furthermore, the findings of this study indicated that the relationship between the mother's play beliefs and preschoolers' happiness was sequentially mediated by the creative home environment and preschoolers' playfulness. Conclusion/Implications: Findings of this study provide insights into the potential development of a parent education program aimed at modifying mothers' play beliefs and the home environment.
