The study was examined the multiple mediated effects of maternal self-efficacy and depression between perception gap about paternal involvement and marital conflict for dual-income parents. The data used were the fifth year data of the Panel Study on Korean Children from Korea Institute of Child Care and Education in 2012. The subjects consisted of 449 dual-income parents with more than one child. Data were analyzed using descriptive statistics, one-way analysis of variance, paired t -test, and correlation. SPSS macro and bootstrapping methods also assessed the mediation effects of maternal self-efficacy and depression between the perception gap about paternal involvement and marital conflict in dual-income parents. The results of this study were as follows. Significant positive correlations were observed for marital conflict, perception gap of dual-income parents about paternal involvement and maternal depression. Perception gaps by parents and self-efficacy were negatively correlated. Perception gaps by parents showed a direct effect on marital conflict. The results of indirect effects of all mediators showed the mediated effect of maternal self-efficacy and depression. The study revealed that the perceptive gap about paternal involvement has a significant impact on maternal self-efficacy and depression, as well as marital conflict. The perceptive gap of dual-income parents about paternal involvement has critical effects on marital conflict as much as the quantity of paternal involvement.

Purpose: The purpose of the study was to investigate the mediating effects of self-efficacy on the relationship between job stress and turnover intention of paramedics in hospitals. Methods: A self-reported questionnaire was completed by 209 paramedics in hospitals from September 4 to 24, 2015. Data were analyzed by descriptive statistics, t-test, ANOVA, Pearson's correlation coefficients, and multiple regression analysis using Baron & Kenny's 3 step procedure. Indirect effect was confirmed with Sobel test using SPSS/Win 22.0 program. Results: There were negative relationships between job stress, self-efficacy, and turnover intention (r=-.509, p<.001). There was a negative relationship between job stress and self efficacy (r=-.821, p<.001). The self-efficacy and turnover intention showed a positive relationship (r=.636, p<.001) with job stress and turnover intention. Concerning the mediated effect of self efficacy on job stress and turnover intention, the influence of job stress at step 2 on turnover intention was significant (B=1.207, p<.001), while job stress at step 3 had significant influence on turnover intention (B=.474, p<.001). The mediated effect of self-efficacy on job stress and turnover intention showed significant partially mediated effect of self-efficacy (z=7.100, p<.001). Conclusion: Improvement of self-efficacy and job stress was effective at decreasing turnover intention in paramedics in hospitals.

Background: This study aimed to examine the impact of chronotype on depressive symptoms and explore the mediating effects of sleep quality, pre-sleep cognitive arousal, and social jetlag in a sample of wage earners. Methods: A total of 3,917 waged workers were surveyed online in July 2022. Logistic regression and mediation analysis were used to assess the relationship between chronotype (morningness, intermediate, and eveningness) and depressive symptoms (Patient Health Questionnaire ≥ 5), and the mediating effects of Insomnia Severity Index (ISI), Pittsburgh Sleep Quality Index (PSQI), and Pre-Sleep Arousal Scale (PSAS). All analyses were adjusted for age, education level, income level, marital status, coffee consumption, alcohol consumption, physical activity, occupation, employment status, and working hours to calculate odds ratios (ORs). Results: The chronotypes of all the participants were divided into morningness (4.7%), intermediate (93.5%), and eveningness (1.8%). Multiple logistic regression analysis showed an increased risk of depression in the eveningness chronotype (OR: 2.96; 95% confidence interval [CI]: 1.51, 5.86). Regarding the mediation analysis, ISI mediated 28.44% (95% CI: 16.39-40.5), PSQI for 31.25% (95% CI: 19.36, 43.15), and PSAS-Cognitive Score (PSAS-C) for 23.58% (95% CI: 10.66, 36.50) of the association between chronotype and depressive symptoms. However, social jetlag did not significantly mediate this relationship. (percentage mediated = 0.75%, 95% CI: -3.88, 5.39) Conclusions: Evening chronotypes exhibit an increased risk of depressive symptoms, which ISI, PSQI, and PSAS-C partially mediated. This suggests that interventions to improve sleep quality and maintain adequate sleep habits may effectively prevent and treat depression in employees with an eveningness chronotype.

The purpose of this study was to understand the effects of hotel employees' physical attractiveness on person-job fit and to empirically analyze whether self-esteem and self-efficacy play a mediating role in the causality between an employee's physical attractiveness and person-job fit. Self-administered questionnaires were completed by 345 employees and the data were analyzed by frequency analysis, factor analysis, reliability analysis, correlation analysis and multiple regression analysis. The primary results were as follows: Multiple regression analysis showed that hotel employee physical attractiveness had a positive significant influence on self-esteem ($\beta=.504$, p<.001) and self-efficacy ($\beta=.441$, p<.001). Also, employee selfesteem ($\beta=.281$, p<.001) and self-efficacy ($\beta=.478$, p<.001) each had a positive significant influence on person-job fit. As a result of analyzing the mediating role, the effect of hotel employees' physical attractiveness on person-job fit was partially mediated by self-esteem and self-efficacy.

to more effectively drive immune responses toward antigen-specific T helper type 2 (Th2) cell-mediated responses, we constructed a mammalian expression vetor (oPVA/IL4) carrying a fused gene in which the ovalbumin (OVA) cDNA was covalently linked to murine interleukin-4 (IL-4) cDNA. A biologically active OVA/IL4 DNA, as demonstrated by Wes tern blotting and cytokine bioassay. In tramuscular injection of BALB/c mice with the pOVA/IL4 DNA increased both the production of OVA-specific IL-4 by CD$4^{+}$ T cells and the ratio of anti-OVA lgG1 to anti-OVA lgG2a isotypes, while the injection with the pOVA DNA alone, or with the mixture of the pOVA and pIL4 DNA did no or little increase. furthermore, the OVA-specific, Th2 cell-mediated immune responses were significantly enhanced by multiple injections with the pOVA/IL4 DNA. These studies indicate that the direct linkage of an OVA gene to an IL-4 gene in the expression plasmid confines the effects of IL-4 to the OVA-specific cells, efficiently driving the immune response toward OVA-specific, Th2 cell-mediated responses.

This study investigated the relationships among emotion knowledge, negative emotionality, and autobiographical memory in a sample of 131 three- to five-year-old children attending day care center in seoul. The collected data were analyzed using simple regression and hierarchical multiple regression. The main results of this study were as follows. First, children's emotion knowledge exerted negative effects on their negative emotionality. Second, children's negative emotionality had a positive influence on their autobiographical memory. Finally, the effect of children's emotion knowledge on their autobiographical memory was partially mediated by their negative emotionality. These findings provide a preliminary evidence that children's emotion knowledge and negative emotionality may predict their autobiographical memory.
