Objective: The purpose of this study was to investigate the effects of parenting stress of mothers, warm parenting behaviors and controlling parenting behaviors on children's social competence. Methods: A total of 1515 mothers of young children(780 boys, 735 girls), who had participated in wave 7 of the Panel Study on Korean Children(PSKC), answered the questionnaires. The questionnaires included items about mothers' parenting stress, parenting behaviors, and their children's social competence. The collected data were analyzed using descriptive statistics, Pearson's correlation and structural equation models using SPSS 23 and AMOS 22. Results: First, there was a significantly negative correlation between mothers' parenting stress and children's social competence. Also, there was a significantly positive correlation between mothers' warm parenting behaviors and controlling parenting behavior and children's social competence. Second, mothers' parenting stress showed a direct negative effect on children's social competence. Third, mothers' warm parenting behaviors and controlling parenting behaviors showed partial mediating roles in the relationship between mothers' parenting stress and children's social competence. Conclusion/Implications: In order to develop positive social competence of children, programs and social support are needed to reduce mothers'parenting stress and induce positive parenting behaviors.

Cerebral monoamines play important roles as neurotransmitters that are associated with various stressful stimuli. Some components such as ginsenosides (triterpenoidal glycosides derived from the Ginseng Radix) may interact with monoamine systems. The aim of this study was to determine whether ginsenoside Rb1 can modulate levels of the monoamines such as dihydroxyphenylalanine (DOPA), dopamine (DA), norepinephrine (NE), epinephrine (EP), 3,4-dihydroxyphenylacetic acid (DOPAC), 5-hydorxytryptamine (5-HT), 5-hydroxindole-3-acetic acid (5-HIAA), and 5-hydroxytryptophan (5-HTP) in mice frontal cortex and cerebellum in response to immobilization stress. Mice were treated with ginsenoside Rb1 (10 mg/kg, oral) before a single 30 min immobilization stress. Acute immobilization stress resulted in elevation of monoamine levels in frontal cortex and cerebellum. Pretreatment with ginsenoside Rb1 attenuated the stress-induced changes in the levels of monoamines in each region. The present findings showed the anti-stress potential of ginsenoside Rb1 in relation to regulation effects on the cerebral monoaminergic systems. Therefore, the ginsenoside Rb1 may be a useful candidate for treating several brain symptoms related with stress.

Objective: The purpose of this study was to examine the relationship between child care teachers' emotional intelligence, communicative competence, and job stress. Methods: Four hundred and fifty child care teachers answered questionnaires on three research variables. Data were analyzed by correlation analyses and regression analyses. Results: First, child care teachers' emotional intelligence, i.e. self-emotion appraisal, others' emotion appraisal, uses of emotion, and regulation of emotion, were negatively related to job stress. Second, child care teachers' emotional intelligence, i.e. self-emotion appraisal, others' emotion appraisal, uses of emotion, and regulation of emotion, were positively associated with communicative competence. Third, child care teachers' communicative competence was negatively linked to job stress. Lastly, child care teachers' communicative competence partially mediated the relationship between self-emotion appraisal, others' emotion appraisal, regulation of emotion, and job stress, and child care teachers' communicative competence fully mediated the relationship between uses of emotion and job stress. Conclusion/Implications: This study suggests that high emotional intelligence and effective communication are important in order to reduce child care teachers' job stress.

The plant-specific NAC transcription factors control various biological processes, including plant development and stress responses. We have isolated an ANAC032 gene, one of the NAC transcription factor family, which was highly activated by multi-abiotic stresses, including high salt and drought in Arabidopsis. Here, we generated transgenic plants constitutively expressing ANAC032 and its knockout to identify the functional roles of ANAC032 in Arabidopsis under abiotic stress responses. The ANAC032-overexpressing plants showed enhanced tolerance to salinity and drought stresses. The anac032 knockout mutants were observed no significant changes under the high salt and drought conditions. We also monitored the expression of high salt and drought stress-responsive genes in the ANAC032 transgenic plants and anac032 mutant. The ANAC032 overexpression upregulated the expression of stress-responsive genes, RD29A and ERD10, under the stresses. Thus, our data identify that transcription factor ANAC032 plays as an enhancer for salinity and drought tolerance through the upregulation of stress-responsive genes and provides useful genetic traits for generating multi-abiotic stress-tolerant forage crops.

Purpose: Child Health nurse practitioners (CHNPs) in Korea have important roles in disease management and health promotion for children and adolescents. Yet, practices of CHNPs licensed and employed in hospitals have not been adequately identified. Thus, in this study the scope of practice by CHNPs and job satisfaction and stress were investigated and compared according to the CHNPs' position in the working place. Methods: A descriptive cross-sectional survey design was used. All 53 licensed CHNPs participated in the mail survey which included a 71-item questionnaire on job performance and job satisfaction and a job contents questionnaire. Descriptive statistics, ${\chi}^2$ test, independent t-test and Mann-Whitney U test were used to compare CHNPs employed as nurse practitioner (NP) and CHNPs employed as staff nurses. Results: Compared to CHNPs employed as staff nurses, CHNPs employed as NPs more frequently provided education, environment management, coordination and research in their practice areas. No significant difference was found in job satisfaction between the two groups except for the administration and income subdomains. Only the physical exertion subdomain in job stress was stressful to CHNP employed as staff nurse. Conclusions: Job performance of CHNPs in Korea needs to be revised to include more practical practice in education, coordination, and research related areas.

MYB-type transcription factors (TFs) play important roles in plant growth and development, and in the rapid responses to unfavorable environmental conditions. We recently reported the isolation and characterization of a rice (Oryza sativa) MYB TF, OsMYB102, which is involved in the regulation of leaf senescence by downregulating abscisic acid (ABA) biosynthesis and the downstream signaling response. Based on the similarities of their sequences and expression patterns, OsMYB102 appears to be a homolog of the Arabidopsis thaliana AtMYB44 TF. Since AtMYB44 is a key regulator of leaf senescence and abiotic stress responses, it is important to examine whether AtMYB44 homologs in other plants also act similarly. Here, we generated transgenic Arabidopsis plants expressing OsMYB102 (OsMYB102-OX). The OsMYB102-OX plants showed a delayed senescence phenotype during dark incubation and were more susceptible to salt and drought stresses, considerably similar to Arabidopsis plants overexpressing AtMYB44. Real-time quantitative PCR (RT-qPCR) revealed that, in addition to known senescence-associated genes, genes encoding the ABA catabolic enzymes AtCYP707A3 and AtCYP707A4 were also significantly upregulated in OsMYB102-OX, leading to a significant decrease in ABA accumulation. Furthermore, protoplast transient expression and chromatin immunoprecipitation assays revealed that OsMYB102 directly activated AtCYP707A3 expression. Based on our findings, it is probable that the regulatory functions of AtMYB44 homologs in plants are highly conserved and they have vital roles in leaf senescence and the abiotic stress responses.

The purpose of this study is to explore various environmental factors that explain parenting practices. Those factors considered are stress and characteristics of single-mother/child together with psychological distress experienced by the single mother. A total of 285 poor single mothers with a child attending elementary school or junior high school completed a structured questionaire. The relationships among the variables were analyzed by the path analysis. The results showed that poor single mothers rely on affectiv $e^portive involvement more frequently then punitive/inconsistent discipline. It is also confirmed that the enviromental factors such as financial stress living environmental stress and job status play important roles in determining the quality of parenting practices with the mediating role of psychological distress.ss.
