This study examined the structural relationships among parent's play participation, children's playfulness, self-regulation and happiness. In this Study, subjects were 274 children who were 4 through 5 years old. The participants included 274 preschoolers' parents and their teachers in D city. The parents completed questionnaires regarding parent's play participation with their children and children's self-regulation. The teachers completed questionnaires regarding preschoolers' happiness and playfulness. Data was analyzed using descriptive statistics, pearson correlation analysis and mediation analysis based on structural equation modeling with SPSS 25.0 and AMOS 23.0 program. Also, specific indirect effects were analyzed using AMOS user-defined estimand function. The primary results of this study were as follows. 1) The parent's play participation had an influence upon children's playfulness and self-regulation. 2) The children's playfulness had an influence upon children's self-regulation and happiness. 3) The children's self-regulation had an influence upon children's happiness. 4) Between the parent's play participation and children's happiness were mediated by the children's playfulness and self-regulation. This study revealed that parent's play participation, children's playfulness and self-regulation need to be considered simultaneously to explain the level of the children's happiness. The results highlight the structural relationships among parent's play participation, children's playfulness, self-regulation and happiness.

Chromosomes located in the nucleus form discrete units of genetic material composed of DNA and protein complexes. The genetic information is encoded in linear DNA sequences, but its interpretation requires an understanding of three-dimensional (3D) structure of the chromosome, in which distant DNA sequences can be juxtaposed by highly condensed chromatin packing in the space of nucleus to precisely control gene expression. Recent technological innovations in exploring higher-order chromatin structure have uncovered organizational principles of the 3D genome and its various biological implications. Very recently, it has been reported that large-scale genomic variations may disrupt higher-order chromatin organization and as a consequence, greatly contribute to disease-specific gene regulation for a range of human diseases. Here, we review recent developments in studying the effect of structural variation in gene regulation, and the detection and the interpretation of structural variations in the context of 3D chromatin structure.

This study examined the structural relationships among the child's playfulness, self-regulation, and ego-resilience. Through an examination of these relationship, this research aimed to analyze the direct and indirect influences of the child's playfulness on self-regulation and ego-resilience. The participants of this study consisted of 359 children attending kindergartens in the Seoul and Gyeonggi-do area. The sample was analyzed using the SPSS 21.0, AMOS 21.0, and Maximum Likelihood method (ML). The significance of the indirect effects was tested by means of bootstrapping. The results of this study were as follows: (i) the child's playfulness had a direct influence on relational ego-resilience; (ii) the child's playfulness directly affected self-regulation; (iii) the child's self-regulation directly affected relational and aptitudinal ego-resilience; and (iv) the child's playfulness was indirectly influential to relational resilience and resilient competency through self-regulation. The discussion also took into account the specific methods which can be used to enhance the child's playfulness and self-regulation.

Objective: The purpose of this study was to explore the structural relationships of child negative emotionality, mother rejective parenting, teacher-child conflict, and child emotion regulation on child aggression. Methods: The participants in this study were 3- to 5-year-old kindergarten children, their mothers, and their teachers (all of whom lived in Busan). The data were analyzed using PASW Statistics 18.0 and AMOS 21.0. For data analysis, frequency, Cronbach's alphas, Pearson's correlation coefficients, SEM were used. Results: First, mother rejective parenting had an indirect effect on child aggression through child emotion regulation. Second, teacher-child conflict had a direct effect on child aggression and had an indirect effect on child aggression through child emotion regulation. Third, child negative emotionality had an indirect effect on child aggression through mother rejective parenting and teacher-child conflict and child emotion regulation. Conclusion: These finding suggest the importance of mediating effect of mother rejective parenting, teacher-child conflict and child emotion regulation between child negative emotionality and aggression.

The purpose of this study examined the path model of maternal emotional expression, temperament and self-esteem on emotion regulation among children. The subjects were 487 5th and 6th graders. Data was gathered through questionnaires reported by children and their mothers and analyzed by structural equation modeling. The results showed that children's 'activity level' temperament and maternal negative emotional expression directly affected maladaptive emotion regulation. Children's 'emotionality' temperament and maternal positive emotional expression directly affected adaptive emotion regulation. Children's 'approach-flexibility' temperament and self-esteem directly affected both maladaptive and adaptive emotion regulation. Maternal emotional expression and children's self-esteem mediated between children's temperament and emotion regulation. Additionally, the most important variable predicting children's maladaptive emotion regulation was the children's 'activity level' temperament, and the most important variable for adaptive emotion regulation was the children's 'emotionality' temperament.

This study examined the effects of maternal grandmothers' positive parenting behavior, mothers' emotion regulation, and positive parenting behavior on children's emotion regulation. A total of 348 mothers of fourth and fifth graders responded to questionnaires, which included items related to their mothers' positive parenting behavior, their own emotion regulation and positive parenting behavior, and their children's emotion regulation. The data were analyzed by means of correlations and Structural Equation Modeling (SEM). First, maternal grandmothers' positive parenting behavior significantly affected mothers' emotion regulation, but mothers' emotion regulation did not directly affect their children's emotion regulation. Second, maternal grandmothers' positive parenting behavior had an effect on mothers' positive parenting behavior, which led to a high level of their children's emotion regulation. Lastly, maternal grandmothers' positive parenting behavior indirectly influenced children's emotion regulation through mothers' emotion regulation and positive parenting behavior. This study emphasizes the intergenerational transmission of positive parenting, as well as a crucial influence of mothers' positive parenting behavior on children's emotion regulation.
