Objective: The purpose of this study was to explore the mediating effects of executive function and emotion regulation of preschoolers on the relationships between mothers' affective parenting and preschoolers' peer competence. Methods: The participants were 3 to 5 year old preschoolers and their mothers (N = 241) living in Busan and Kyungnam province. Data analysis methods included descriptive statistics, Cronbach ${\alpha}$, Pearson's correlation analysis, and SEM. Data were analyzed using the SPSS Statistics 23.0 program and Amos 23.0 program. Results: The major findings of this study are as follows. First, mothers' affective parenting, preschoolers' executive function, emotion regulation, and peer competence correlated positively. Second, the relationship between mothers' affective parenting and preschoolers' peer competence was mediated by preschoolers' executive function and emotion regulation. Conclusion: These findings suggest the importance of mediating effects of preschoolers' executive function and emotion regulation on the relationship between mothers' affective parenting and preschoolers' peer competence.

This study was to investigate the relationships between stress coping strategies, emotion regulation ability and behavior problems with children from low-income families and middle-income families. Subjects were 171 children from low-income families and 228 children from middle-income families, 4th - 6th grade in elementary school. The major findings are followings: (1) The level of emotion regulation ability in children from low-income families was lower and active stress coping strategies were less than children from middle-income families. In the behavior problem, children from low-income families were higher than children from middle-income families. (2) The stress coping strategies(active/ social support) in children from low-income families were related with internal behavior problem(anxiety /withdrawal). And the emotion regulation ability was related to the children's behavior problem. (3) Regression analysis model showed that emotion-regulation ability was the most influential factor to the children's behavior problem, and children from low-income families with aggressive coping strategy showed hyperactive behavior problem. So, the education/therapy programs for children from low-income families have to be developed and practiced in schools, local children centers and so on.

Accumulating evidence indicates many brain functions are mediated by epigenetic regulation of neural genes, and their dysregulations result in neuronal disorders. Experiences such as learning and recall, as well as physical exercise, induce neuronal activation through epigenetic modifications and by changing the noncoding RNA profiles. Animal models, brain samples from patients, and the development of diverse analytical methods have broadened our understanding of epigenetic regulation in the brain. Diverse and specific epigenetic changes are suggested to correlate with neuronal development, learning and memory, aging and age-related neuronal diseases. Although the results show some discrepancies, a careful comparison of the data (including methods, regions and conditions examined) would clarify the problems confronted in understanding epigenetic regulation in the brain.

The intestinal immune system has an ability to distinguish between the microbiota and pathogenic bacteria, and then activate pro-inflammatory pathways against pathogens for host defense while remaining unresponsive to the microbiota and dietary antigens. In the intestine, abnormal activation of innate immunity causes development of several inflammatory disorders such as inflammatory bowel diseases (IBD). Thus, activity of innate immunity is finely regulated in the intestine. To date, multiple innate immune cells have been shown to maintain gut homeostasis by preventing inadequate adaptive immune responses in the murine intestine. Additionally, several innate immune subsets, which promote Th1 and Th17 responses and are implicated in the pathogenesis of IBD, have recently been identified in the human intestinal mucosa. The demonstration of both murine and human intestinal innate immune subsets contributing to regulation of adaptive immunity emphasizes the conserved innate immune functions across species and might promote development of the intestinal innate immunity-based clinical therapy.

This study examined the effects of family climate, peer support and self-esteem on children's self-regulation. The participants in this study were 369 children (M=11.78 year) who completed questionnaires regarding family climate, peer support, self-esteem and self-regulation. Data were analyzed means by of a Structural equation model using AMOS 7.0. Our results indicated that (1) family climate, peer support and self-esteem were directly linked with children's self-regulation (2) the associations between family climate or peer support and children's self-regulation were mediated by children's self-esteem. These results imply that family climate and peer support are important antecedent variables in predicting children's self-regulation as well as their relative levels of self-esteem.

The purpose of this study was to examine the path model of child's sex, temperament, maternal parenting behavior, and child's emotion regulation on child social behaviors. The subjects were 286 elementary school children. Data were gathered through questionnaires reported by mothers and teachers. Path analysis revealed that (1) mother's overprotective or coercive parenting behaviors effected neither child's emotion regulation nor social behaviors (2) child's sex and activity level effected child's aggression both directly and indirectly through child's emotion regulation (3) child's 'activity level' and 'avoidance' temperament effected child's social withdrawal both directly and indirectly through child' emotion regulation. Findings underscore the role of emotion regulation as a mediator in predicting child aggression and social withdrawal.

This study examined the relationship between COVID-19 stress, self-regulation, and smartphone addiction among university students. It also assessed whether self-regulation mediates the relationship between COVID-19 stress and smartphone addiction. The participants comprised 346 students enrolled in G city university. Data were analyzed using SPSS and AMOS to generate descriptive statistics, perform a correlation analysis, and create a structural equation model. The main findings were as follows. First, COVID-19 stress had a negative correlation with self-regulation, but a positive correlation with smartphone addiction. A negative correlation was observed between self-regulation ability and smartphone addiction. Secondly, self-regulation partially mediated the relationship between COVID-19 stress and smartphone addiction. The results will inform educational and counseling interventions aimed at preventing smartphone addiction among university students living in the era of the COVID-19 pandemic.

We review the research literature on relationship between environmental regulation and industrial development in three aspects of environmental regulation and investment, environmental regulation and efficiency, environmental regulation and trade. Indeed, the linkage between environmental regulation and material consumption of industrial system is absent. Environmental regulation is measured as the expenditure share for industrial pollutants abatement, and effluent charge intensity. Using panel-level data from 31 provinces, municipalities and autonomous regions in China, we build correlation models between material consumption and environmental regulation, results show that: (1) there are significant quadratic function relationship between material consumption and environmental regulation. And there is the fact that inflection point exists. (2) On basis of inflection points, we make two remarkable reflections. Firstly, the inflection points are the most important scale to judge reasonability and performance of regulations. Secondly, a Pareto improvement may occur when the regulations achieve a certain target. (3) Both intensities of industrial pollutants abatement expenditure and effluent charge have not yet achieved the expected target in most regions of mainland China at present. And most of regions of material consumption decreasing are distributed in western China. Main reasons lie in the impacts of industrial features as well as the regulations.

This study examined the regulation status on wastewater treatment in agro-food processing and a case study on effluent treatment m ethods was carried out to evaluate any change after the mitigation of regulation. First, in order to clarify the area of investigation, the definition of small-scale agro-processing facilities was reviewed through literature survey and local government ordinance. The current law were separately analyzed into four areas; effluent treatment facilities, development of agro-processing industries, land use and food processes equipment. The exclusion clauses on wastewater discharging facility in the enforcement regulation were defined in detail, which can be served in practice. Site survey, after the questionnaire survey of the person in charge of the local unit, was carried out. As the result, this survey confirmed the positive effects of the deregulation on promoting sewer system service in rural areas, introducing the new processing construction and so on. In addition, it was found that some matters to be considered to determine whether to introduce wastewater treatment plan for public food processing facilities.

The developmental regulation of Caenorhabditis elegans DNA topoisomerase I expression was examined using synchronized Caenorhabditis elegans cultures. Variations of the relative mRNA and protein levels of the enzyme during their development were measured by Northern and Western analyses, respectively. The mRNA level was the highest at the embryonic stage, decreasing rapidly to the one tenth level at the L1 stage, and then increasing by a few fold at the L4 and young adult stages. The protein level was the highest at the L1 stage, with gradual decreasing at the following stages until it showed a slight increase at the young adult stage. Based on our results of the expressional regulation, the possible roles of DNA topoisomerase I in the development of C. elegans are discussed.
