Purpose: The purpose of this study is to demonstrate the mediating effect of happiness in the relationship between internet addiction, depression and suicidal ideation among adolescents from multicultural families. Methods: 1,065 adolescents from multicultural families who participated in the 16th (2020) Adolescent Health Behavior Survey were selected as the final subjects for the study, and were analyzed with descriptive statistics, independent t-test, ANOVA, Pearson's correlation coefficient, and stepwise multiple regression. Results: There was a fully mediating effect of happiness in the relationship between internet addiction and suicidal ideation of the adolescents from multicultural families (F=6.65, p<.001). There was a partial mediating effect of happiness in the relationship between depression and suicidal ideation of the adolescents from multicultural families (F=10.01, p<.001). Conclusion: To mitigate the suicidal ideation of adolescents from multicultural families, it is necessary to develop and apply a positive psychological treatment program that enhances happiness for adolescents from multicultural families who are experiencing internet addiction and depression.

This study examined the resilience factors of multi-cultural families using depth interviews. Thirty-one multi-cultural families(totaling 98 individuals) were interviewed on a range of issues, including the process of marriage, the attitude of international marriage, family relations, social networks, the process of social adaptation, and their needs for specific social services. The resilience theory was used to categorize resilience factors, multi-cultural families. Analysis of results from depth interviews identified three broad resilience factors. The first was related to for belief systems which included 'family's common goal', The second was related to family functioning systems which included 'family cohesion', 'family adaptability', and 'satisfaction for role-expectation'. The third was related to social networking which included 'satisfaction from social activities'. These resilience factors helped multi-cultural families cope with stressful events and risk situations related to every day life. Results from this study imply that multi-cultural families possess the abilities to lead a meaningful and healthy life-style regardless of obstacles such as communication difficulties, cultural differences, and societal stigma.

This study clarifies the definition of and to provides guidelines on educational objectives, core concepts, and content in developing a Human Rights Education Program for families. The Delphi survey method was used to develop a Human Rights Education Program for families. As a result, a Human Rights Education Program for families was defined as education that would ensure all members of the family enjoy universal human rights without discrimination. In addition, that the prejudice and discrimination against socially marginalized would not be created within the family by learning values and attitudes that respects human rights and freedom. The objectives were to learn the merit of respecting individuals, relationships, and community. Core concepts of the program were the rights for myself and others, communicating and responsibilities and a sense of citizenship. Content included human rights, respect of oneself and others, empathetic understanding, acceptance, communication in an intimate relationship, conflict management, sharing the role of caring the family, no discrimination against the socially marginalized, and creating an inclusive community culture. This study can be used as a guideline for family human rights education based on family human rights, which is the core of family democracy.

The purpose of this study is to investigate low- and middle-income preschoolers' pretend negotiation. Pretend negotiation of 78 five-year-old children were analyzed by children's sex and their socioeconomic status. Dyads were participated in social pretend play session during 20 minutes. The play session was videotaped and the videotaped data were transcribed. Each transcript was analysed according to the modified version of Howe et al. (1998)'s coding schemes. Results showed that children from middle-income families were higher in directive and responsive pretend negotiation than children from low-income families. And girls from middle-income families were higher in pretend negotiation (play role) than girls from low-income families.

Histone deacetylases (HDACs) play a pivotal role in epigenetic regulation, affecting the structure of chromatin and gene expression across different stages of plant development and in response to environmental stresses. Although the role of HDACs in Arabidopsis and rice has been focused on in extensive research, the role of the HDAC gene family in various medicinal plants remains unclear. In the genome of the balloon flower (Platycodon grandiflorus), we identified 10 putative P. grandiflorus HDAC (PlgHDAC) proteins, which were classified into the three families (RPD3/HDA1, SIR2, and HD2 HDAC families) based on their domain compositions. These HDACs were predicted to be localized in various cellular compartments, indicating that they have diverse functions. In addition, the tissue-specific expression profiles of PlgHDACs differed across different plant tissues, indicating that they are involved in various developmental processes. Furthermore, the expression levels of all PlgHDACs were upregulated in leaves after waterlogging treatment, implying their potential role in coping with waterlogging-induced stress. Overall, our findings provide a comprehensive foundation for further research into the epigenetic regulation of PlgHDACs, and particularly, on their functions in response to environmental stresses such as waterlogging. Understanding the roles of these HDACs in the development and stress responses of balloon flower could have significant implications for improving crop yield and the quality of this important medicinal plant.

The purposes of this article are to find out general trends of dual-career couples' role expectations role conflicts and marital satisfactions and to estimate the differences according to related variables and to analyze the effects of indepedent variables on ole conflicts and marital satisfactions. For these objectives two kinds of questionaire were used and the data were obtained through 169 dual-career couples. The results were as follows; The results were as follows; 1) Dual-career couples' role expectations and marital satisfactions were relatively high but role conflicts were not. Husbands' role expectations were higher than them of wives but wive's role conflicts and marital satisfactions were higher than them of husbands. 2) Dual-career couples' role expectations role conflicts and marital satisfcations were significantly different by communication role related variables and job related variables. 3) Husbands' role conflicts and marital satisfactions were significantly influenced by communication satisfaction and role expectations,. Wives' role conflicts and marital satisfactions were significantly influenced by communication satisfaction husbands' housework aid and role expectations.

This study was based on a recognition that the married mens role of performing multiple roles should be redefined. Family and work roles were composed of four domains, such as marital, parental, homecare, and occupational roles. The data of this study had been collected from the married men, who had his spouse and his first child younger than twelve years old, and held a job in Seoul. The main findings of this study were as follows: First, as for family and work role salience perceptions, it showed that men relatively higher perceived four role saliences: marital role salience, parental role salience, homecare role salience, and occupational role salience. Second, among four salience perceptions of family and work roles, married men highest perceived homecare role salience while they lowest perceived occupational role salience. Third, regarding the married mens family and work role performances, the parental and homecare roles were equally performed and higher than the marital and occupational roles. In general, the degree of family and work role salience perceptions of the married men in Korean society was higher than that of family and work role performances.

The purpose of this study was to describe the current status of dual-earner families in Seoul. The specific aims of this study were to examine the dynamics of marital relationship, parent-child relationship and old mother-daughter/daughter in law relationship in the same family. The sample consised of 265 dual-earner families was selected based on wives' jobs, primarily non-professional. The information was gathered from working couples and their school-aged children. The findings of this study were as follows: 1. Sex role attitude of husbands was more traditional than their wives. Therefore, housework sharing of husbands was very low and wives' perception of inequity was high. Wives' marital satisfaction was affected by the wives' perception of inequity, joint leisure activity, sexual satisfaction, and wives' job satisfaction. Husbands' marital satisfaction was affected by sexual satisfaction, perceived difficulties and problems of the husbands caused by wives' employment, and the degree of their housework participation. 2. The emotional uneasiness of children during mothers' absence was reported. The communication about mothers' job was helpful to gain children's understanding toward mothers' job. Mothers suffered from guilty feeling of neglecting their children in spite of their good performance of mothering role. 3. The employed daughters/daughters in law perceived high rewards and low cost in relationships with their mothers/mothers in law. The perceived quality of daughter-mother relationship was higher with low cost and high rewards than that of daughter in law/mother in law. Finally practical and policy implications were suggested.

Long terminal repeat retrotransposons (LTR-Rs) are major elements creating new genome structure for expansion of plant genomes. However, in addition to the genome expansion, the role of LTR-Rs has been unexplored. In this study, we constructed new reference genome sequences of two pepper species (Capsicum baccatum and C. chinense), and updated the reference genome of C. annuum. We focused on the study for speciation of Capsicum spp. and its driving forces. We found that chromosomal translocation, unequal amplification of LTR-Rs, and recent gene duplications in the pepper genomes as major evolutionary forces for diversification of Capsicum spp. Specifically, our analyses revealed that the nucleotide-binding and leucine-rich-repeat proteins (NLRs) were massively created by LTR-R-driven retroduplication. These retoduplicated NLRs were abundant in higher plants, and most of them were lineage-specific. The retroduplication was a main process for creation of functional disease-resistance genes in Solanaceae plants. In addition, 4-10% of whole genes including highly amplified families such as MADS-box and cytochrome P450 emerged by the retroduplication in the plants. Our study provides new insight into creation of disease-resistance genes and high-copy number gene families by retroduplication in plants.
