This study aimed to identify the actor and partner effects of parenting efficacy, spousal support on parenting stress and depression in couples with children with attention deficit hyperactivity disorder (ADHD). Methods: A cross-sectional survey design was used. Participants were 103 couples (103 husbands, 103 wives) with children with ADHD visiting child adolescent psychiatry clinic or community mental health center in Seoul, Gyeonggi-do, South Korea. Data were analyzed by SPSS 20.0 and AMOS 20.0 program. Results: The parenting efficacy of husbands and wives had direct actor effect (β=-.69, p=.004; β=-.60, p=.004) and partner effect (β=-.22, p=.007; β=-.18, p=.026) on their parenting stress. In addition, husbands and wives's parenting efficacy had a direct actor effect (β=-.25, p=.031; β=-.21, p=.025) on their depression and indirect actor effect (β=-.25, p=.004; β=-.34, p=.004) through parenting stress on their depression. However, parenting stress did not show a partner effect on depression. Husband and wife's parenting efficacy had a direct effect (β=.46, p=.004; β=.25, p=.009) on perceived spousal support. The effects of husbands and wives were the same in actor effect size (χ² differences=0.74, p=.390) and partner effect size (χ² differences=0.20, p=.652) of parenting efficacy on parenting stress. In addition, the effect sizes of husbands and wives were the same in actor effect size (χ² differences=0.93, p=.334) and partner effect size (χ² differences=0.15, p=.704) for parenting stress and depression. Conclusion: The results of this study may provide the foundation for developing a nursing intervention program that can maximize interaction between couples with ADHD children.

In order to improve self-management of elderly hypertensives in this study, the researcher examined the effect of blood pressure regulation by an abdominal relaxed breathing training which regulates physical response to stress and lessens the activity of the sympathetic nerve. Method: A quasi-experimental pre-test and post-test design was used. Thirty elderly hypertensive patient ; Sixteen in the abdominal breathing group and fourteen in the control group participated in this study. The abdominal relaxed breathing training consisted of eight sessions twice a week for four weeks. There was no intervention for the control group. Result: 1. There was a significant decrease in systolic and diastolic blood pressure between the experimental group and control group over three different times, and interaction by groups and over time. 2. There was no significant difference in the level of total stress response, physical stress response, behavioral-cognitive stress response between the experimental group and control group over three different times, and interaction by groups and over time. Conclusion: Findings indicate that this study will contribute to develop nursing strategies for the regulation of blood pressure for the elderly, which is easy for the elderly to learn as a nonpharmacologic approach.

Purpose: This study investigated the moderating role of general self-efficacy (GSE) on how stress caused by pregnancy and daily hassle affect the risk of preterm birth (PTB) in women experiencing preterm labor. Methods: This cross-sectional study included 196 pregnant women experiencing preterm labor before 37 weeks of gestation. We used IBM SPSS Statistics 27 and employed Hayes process macro version 4 (model 1) and hierarchical regression to analyze the moderating effect of GSE on the relationship between pregnancy stress, daily hassle stress, and PTB risk. Results: Stress caused by pregnancy and daily hassle was positively correlated to PTB risk (r = .54, p < .001; r = .25, p < .001, respectively). While GSE did not significantly correlate with pregnancy stress, it negatively correlated with daily hassle stress (r = - .19, p = .009). GSE significantly moderated the relationship between combined stressors and PTB risk. As GSE levels increased, escalation in PTB risk in response to increasing stress levels was a more pronounced, highlighting a complex interaction between higher GSE levels and response to escalating stress levels. This model accounted for 39.5% of the variance in the PTB risk. Conclusion: Higher GSE may amplify the impact of stress on PTB risk, rather than mitigate it, which suggests a more nuanced role of GSE in the stress response of pregnant women at risk of preterm labor. GSE should be considered in care strategies, and managing its impact on stress perception and responses in pregnant women is crucial.

The load interaction effect can be best illustrated by the phenomenon of overload retardation. Some prediction methods for retardation are reviewed and the problems discussed in the present paper. The so-called under-load effect much of the retardation disappears if a very low level minimum stress follows the overload, is also of importance for a prediction model to work properly under random load spectrum. The concept of Interactive Zone (IZ) fully considering reversed plasticity during unloading was discussed. This IZ concept can be combined with existing models to derive some improved models that can naturally take account of the under-load effect. Some simulations by IZ improved models for test under complex load sequences including multiple overloads and both over/under loads are compared with test results. It is seen that the improvement by IZ concept greatly enhanced the ability of existing models to accommodate complex load interaction effects.

This study was to investigate the effects of children's temperament, parenting behavior, and parenting stress on preschool children's prosocial behavior. The subjects were 190 children consisting of five and six years old and their mothers and fathers. They were selected from 6 kindergartens. Data was collected using the children's prosocial behavior index, the children's temperament index, the parenting behavior questionnaire, and the parenting stress questionnaire. The results were statistically analyzed using t-test, correlation analysis and multiple regression analysis. The study showed that there were some significant differences in children's prosocial behavior according to the children's gender, but there were no significant differences according to the children's age. Correlation analysis indicated that the children's prosocial behavior and children's temperament had significant correlation, especially the children's adaptability and activity indicated high positive correlations. In addition, the children's prosocial behavior and mother's warmth acceptance behavior had significant high positive correlation, and father's rejection restriction behavior had significant high negative correlation. Also, correlation analysis indicated that the children's prosocial behavior and the mother's and father's stress of parent-child dysfunctional interaction and educational distress had significant negative correlations. It was also found that children's gender, mother's permissiveness non- intervention behavior, mother's educational distress, mother's stress of parent-child dysfunctional interaction, and father's stress of parent-child dysfunctional interaction were all significant predictors of the preschool children's prosocial behavior.

The purpose of this study was to identify the convergent interaction effects of work environment on the relation between patients related stress and nurse's burnout. Data were collected with a convenience sample of 168 nurses at hospital in Seoul, Korea from 1 July to 15 July 2014. The structured questionnaires measured patients related stress, work environment, and burnout. In the results, patients related stress enhanced burnout. The analysis of moderating effect of work environments to relation between patients related stress to burnout showed that high control, rewards, fairness, and value and low overload reduced the influence of patients related stress to burnout. And community had main effect to burnout. Based on these results, it is necessary to develop nurse's work environment improvement strategies for relieving burnout.

Background: A chronic social defeat stress (CSDS) model has been proposed as relevant to stress-induced behavioral change in humans. In this study, we examined the effect of Korean Red Ginseng (KRG) on CSDS-induced mood disorders and protein expression in an animal model. Methods: To evaluate the effect of KRG on social defeat stress, test mice were exposed in the resident aggressor's home cage compartment for 14 days beginning 1 h after KRG treatment (10, 20, and 40 mg/kg, per oral (p.o.)). After the exposure, behavioral tests to measure anxiety, social interaction, and depression-like behavior were performed. To investigate the underlying mechanism, N-methyl-D-aspartate receptor expression levels in CSDS-induced mice were evaluated using Western blot analysis. Results: CSDS induced anxiety-like behaviors by decreasing central activity in the open-field test and open-arm approach in the elevated plus maze test and led to social avoidance behavior in the social interaction test. CSDS mice showed upregulated NR1, NR2A, and NR2B expression in the hippocampus. KRG 20 and 40 mg/kg ameliorated anxiety-like activities and KRG 20 mg/kg alleviated social avoidance by decreasing time in the corner zone. KRG treatment recovered CSDS-induced NR1, NR2A, and NR2B protein levels in the hippocampus. Conclusion: These results indicate that KRG has a therapeutic effect on CSDS-induced mood disorder by alleviating N-methyl-D-aspartate receptor overexpression in the hippocampus.

Regular exercise training improves body composition, blood lipid profiles and exercise adaptation. This study was conducted to investigate the effect of exercise training at different times of day on body composition, blood lipids, stress hormones and nutrient intakes. Twenty four male graduate students carried out this experiment. The subjects were divided into three groups; morning exercise group, evening exercise group and control group. Two exercise groups performed running and muscular resistance training at mid intensity for 12 week periods. Body composition, blood lipid profiles, blood cortisol, ACTH and nutrient intakes were analyzed prior to, midway and after training. There were significant differences about interaction between different exercise times and training periods in plasma TG and HDL-C of the evening exercise training (p < 0.05). Also the evening exercise group was showed the decreasing of TC after training (p < 0.05). No significant differences about interaction between different exercise times and training periods were shown in body composition, stress hormones and nutrient intakes in the three groups. But evening exercise training decreased body fat ($\%$) and blood ACTH (p < 0.05). Also the increasing of carbohydrate intakes was shown by the evening exercise training (p < 0.05). In contrast, morning exercise group indicated a decrease of body fat ($\%$) after 6 week training (p < 0.05), but this effect was not maintained after 12 weeks of training. These results suggested that regular evening exercise is more effect than morning exercise from the viewpoint of improving body composition, blood lipids, nutrient intakes and exercise adaptation.

The purpose of this study was to investigate the effects of perceived daily stress on the adjustment of children and to examine whether social support has a moderating effect on the relationship between daily stress and adjustment. The results are summarized as follows. First, it was found that stress caused by school, family environments and friends had significant effects on the self-concept of children. In addition, it was found that stress caused by teachers/school and family environments had significant effects on achievement motivation and social behavior. Second, the interaction between daily stress and support from family and friends affected self-concept. Furthermore, achievement motivation was positively affected by the interactions between daily stress and family support, between daily stress and teacher support and between daily stress and friend support.

A comparison was made between the effect of subjective stress and that of objective stress on immune function in male medical college students. Interaction between perceived stress, psychopathology and natural killer-cell(NK) activity was assessed during an exam period, non-exam period, and vacation. No significant difference was found in NK activity among these three periods, but scores of perceived stress related to unusual happenings during an exam period and related to interpersonal relationship during vacation were found to have significantly positive correlation with NK activity, respectively. In psychopathology, only scores of anxiety during an exam period had significantly positive correlation with NK activity. These results suggest that immune function is more likely to be affected by subjective stress than objective stress and that subjective stress such as some perceived stress and subclinical level of anxiety may positively affect immune function.
