Background: The skin is the largest body organ that regulates excretion of metabolic waste products, temperature, and plays an important role in body protection against environmental physical and chemical, as well as biological factors. These include agents that may act as oxidants or catalysts of reactions producing reactive oxygen species (ROS), reactive nitrogen species (RNS), and other oxidants in skin cells. An increased amount of the oxidants, exceeding the antioxidant defense system capacity is called oxidative stress, leading to chronic inflammation, which, in turn, can cause collagen fragmentation and disorganization of collagen fibers and skin cell functions, and thus contribute to skin diseases including cancer. Moreover, research suggests that oxidative stress participates in all stages of carcinogenesis. We report here a summary of the present state of knowledge on the role of oxidative stress in pathogenesis of dermatologic diseases, defensive systems against ROS/RNS, and discuss how physical activity may modulate skin diseases through effects on oxidative stress. The data show duality of physical activity actions: regular moderate activity protects against ROS/RNS damage, and endurance exercise with a lack of training mediates oxidative stress. These findings indicate that the redox balance should be considered in the development of new antioxidant strategies linked to the prevention and therapy of skin diseases.

Background: In this study, the measurement of job stress of electric overhead traveling crane operators and quantification of the effects of operator and workplace characteristics on job stress were assessed. Methods: Job stress was measured on five subscales: employee empowerment, role overload, role ambiguity, rule violation, and job hazard. The characteristics of the operators that were studied were age, experience, body weight, and body height. The workplace characteristics considered were hours of exposure, cabin type, cabin feature, and crane height. The proposed methodology included administration of a questionnaire survey to 76 electric overhead traveling crane operators followed by analysis using analysis of variance and a classification and regression tree. Results: The key findings were: (1) the five subscales can be used to measure job stress; (2) employee empowerment was the most significant factor followed by the role overload; (3) workplace characteristics contributed more towards job stress than operator's characteristics; and (4) of the workplace characteristics, crane height was the major contributor. Conclusion: The issues related to crane height and cabin feature can be fixed by providing engineering or foolproof solutions than relying on interventions related to the demographic factors.

Purpose: The purpose of this study was to identify the influencing factors of mothers' confidence in their maternal role during the early postpartum period. Methods: Participants were 178 postpartum women who delivered at three specialized obstetrics and gynecology facilities and used the postpartum care facility in city B. Data were collected from February to April, 2012 using the scales of measurements of self-confidence in maternal role performance, maternal self-esteem, mother-to-infant attachment, social support, and childcare stress. Descriptive statistics, Pearson correlation coefficients, and stepwise multiple regression were used with the SPSS/WIN 18.0 program to analyze the data. Results: The scores for self-confidence in the maternal role showed significant negative correlations with the scores of childcare stress (r=-.40, p<.001). Parity and maternal attachment were significant predictors and accounted for 97.4% of the variance in self-confidence in the maternal role. Conclusion: To strengthen self-confidence in the maternal role of early postpartum mothers, prenatal class programs need to be complemented in order to reduce childcare stress and promote mother-to-infant attachment.

The purposes of this research were to find out general trends of employed women's stress and to investigate the differences and effects of related variables. The data were obtained through 239 employed women living in Kwangju and Chonnam. The major findings were as follows : 1) Employed women's scores of stressor, stress cognition and distress were under medium but coping scores were relatively high. 2) Significant differences in employed women's stressors were found according to age, income, job satisfaction, and family life cycle. Stress cognition differed according to job adjustment conditions and self-esteem. Also distress related with job conditions and object. Stress coping levels were different according to income, job conditions, self-esteem, and sex-role attitude. 3) In analyzing the causal effects among related variables, employed women's stressors were affected by job satisfaction and age. Also stress cognition were influenced by job satisfation and self-esteem. Job conditions showed significant effects on distress and self-esteem, sex-role attitudes showed on coping. Conclusively job satisfaction, self-esteem and gender equality were most important variables for employed women's stress. (Korean J of Human Ecology 2(1) : 25-37 1999)

Previous studies on the relationship between stress and performance have shown inconsistent results. Thus, this study focused on the effect of challenging stress among the two types of stress types and investigated the nonlinear relationship between the challenging stress and the performance. In particular, performance was divided into job performance, which is related to in-role behavior, and organizational citizenship behavior, which is characterized as extra-role behavior. Empirical results using 222 samples of Chinese workers have showed that challenging stress had a nonlinear relationship with job performance and organizational citizenship behavior. However, it was found that the shape of nonlinear relationship of the challenging stress on job performance and organizational citizenship behavior was slightly different. Finally, the theoretical and practical implications of this paper and future research directions are discussed.

Recently, organizations are increasing their investment to protect information resources from information security(IS) threats through the adoption of IS policies and technologies. However, IS incidents occur in a variety of ways, such as intrusions from outside the organization and exposure to the inside. Our study presented the negative effects of IS role stress on organizational insiders and suggested factors from the organizational and individual perspectives for mitigating IS role stress. We conducted a survey on employees of companies that introduced and applied IS policies to their work and tested the hypothesis using 329 samples. As a result, IS organization justice reduced IS role stress and strengthened IS positive psychological capital, thereby affecting the IS compliance intention of employees. Also, IS positive psychological capital moderated the relationship between IS stress and IS compliance intention. This study contributes to the achievement of internal IS goals by suggesting the conditions that affect the IS compliance behavior of employees in terms of the organizational environment and individual characteristics

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.
