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.

Purpose: This study was conducted to determine factors affecting workers' physiological somatic complain using the Job Stress Model proposed by the National Institute for Occupational Safety and Health (NIOSH). Method: Data were collected from the 1st to the 30th of December 1999. The subjects were 2.123 workers employed at 155 work sites. Collected date were analyzed through SAS/PC program. Result: According to individual characteristics, younger and women groups showed significantly higher physiological somatic complaint than elder men groups. By work condition, groups with higher physiological somatic complaint included workers of irregular shift work. Dark lighting, improper temperature in winter, improper ventilation, inappropriate humidity, unpleasant work environment and crowded work place were significantly related with physiological somatic complaint. By work-related factor, physiological somatic complaint was high in those with higher variance in work load, quantitative work load, role conflict, job burden, role ambiguity and future ambiguity. On the other hand, physiological somatic complaint was low in those with little underutilization of ability. As for the relationships between physiological somatic complaint and non-work related factors, physiological somatic complaint was high in workers who had a side job, were bringing up infants alone, cleaned the house alone, cared for the elderly and disabled persons, were studying, were volunteering at another organization, and were spending 5-10 hours in religious activities per week. Physiological somatic complain was in significantly negative correlations with overall social support, supervisory support and family support, but in significantly positive correlations with co-worker support. Conclusion: The main predictors of physiological somatic complain were gender, shift work pattern, overtime work, ventilation, role ambiguity, role conflict, future ambiguity, job control, variance in work load, overall social support, worker with side job, worker who cleans the house alone, worker who is studying. These predictors explained 19.10% of the total variance of physiological somatic complain.

The purpose of this study is to investigate the relationship between the expenditure on private education and stress from private education, and the role conflicts of the mothers of junior and senior high school students. The subjects were 300 mothers of students who are enrolled in junior and senior high school and receiving private education in Seoul and its suburbs. The results were as follows: First, the level of stress from private education was found to be higher than the scale range of the median, whereas the degree of role conflicts was slightly lower than the scale range of the median. Second, a hierarchical regression analysis was performed by using the expenditure on private education and stress from private education as independent variables and the socio-demographic variables of mothers as the control variables in order to identify their effect on the role conflicts of the mothers of the junior and senior high school students. The results show that the age of the mother, the household monthly income, the monthly expenditure on private education, and stress from private education were significantly related to the role conflicts of the mothers. That is, the older the age of the mother, the lower the level of monthly income, the lower the level of the monthly expenditure on private education, and the higher the level of stress from private education, the greater the degree of the role conflicts of the mother.

Stress and its related hormones epinephrine (E) and norepinephrine (NE) play a crucial role in tumor progression. Macrophages in the tumor microenvironment (TME) polarized to M2 is also a vital pathway for tumor deterioration. Here, we explore the underlying role of macrophages in the effect of stress and E promoting breast cancer growth. It was found that the weight and volume of tumor in tumor bearing mice were increased, and dramatically accompanied with the rising E level after chronic stress using social isolation. What is most noteworthy, the number of M2 macrophages inside tumor was up-regulated with it. The effects of E treatment appear to be directly related to the change of M2 phenotype is reproduced in vitro. Moreover, E receptor $ADR{\beta}2$ involved in E promoting M2 polarization was comprehended simultaneously. Our results imply psychological stress is influential on specific immune system, more essential for the comprehensive treatment against tumors. [BMB Reports 2015; 48(5): 295-300]

This study examined the characteristics of children, parents, family, and the extra context related to the parenting stress of employed and unemployed mothers from a broader perspective. The subjects were 323 employed mothers 3nd 300 unemployed mothers of pre-school age children. Parenting stress due to the role of being a parent for both employed and unemployed mothers was correlated with the chid's activity level, husband support, quality of life, available social support, and satisfaction of early childhood program's location. Parenting stress due to child-rearing of both employed and unemployed mothers was correlated with child's birth order, activity level and rhythmicity of child, husband support, quality of life, available social support, and satisfaction of early childhood program. Number of children was the strongest predictor of parenting stress due to the role of being a parent for employed mothers and the child's activity level for unemployed mothers. Besides, the child's activity level was the strongest predictor of parenting stress due to child-rearing for both employed and unemployed mothers.

This experiment was carried out to examine the roles of selenium in arsenic- and chromium-induced oxidative stress, which results in chromosomal damage, such as sister chromatid exchange (SCE) and chromosomal aberration (CA). For this purpose, the frequency of CA and SCE related to the level of 0xidative stress were analyzed. Selenium decreased the frequency of CA induced by As. In order to evaluate the effect of selenium on clastogenic factors, media from As- and Cr-treated cells were ultrafiltered and added again to cells in the presence or absence of selenium. Selenium decreased the frequency of SCE by As and Cr. This observation indicates the possibility of presence of clastogenic factor. In addition, the clastogenic factor would be involed in oxidative stress since selenium decreased the level of oxidative stress. Thus, it is suggested that selenium may play a role as an anti-clastogenic effector by preventing the oxidative stress, thereby decreasing the frequency of Asand Cr-induced chromosomal damage.

The purpose of this study was to contribute to family nursing for reducing stress and improving coping of the parents of mentally retarded children. Data were collected through self-reported questionnaires during a period of 2 months between November 1994 and January 1995 in the Kyoung-in area. The subjects consist of 180 parents (90 mothers and 90 fathers) of mentally retarded children attending schools for the handicapped and 186 parents (93 mothers and 93 fathers) of normal children. The levels of general stress and of parental role stress were measured with the General stress scale and the Parental role stress scale, respectively, while the Coping scale was adopted to measure the level of coping. The data were analyzed by using Chi-square test. fisher's exact test, Repeated masured ANOVA, oneway ANOVA and Scheffe comparison test. The results were as follows ; 1. The level of general stress was significantly higher in the mothers and the fathers of the men-tally retarded than in the respective parents of the normal. Of the parents, the mothers experienced significantly greater level of general stress than the fathers did in both groups of the retarded and of the normal. 2. As for the parental role stress, the mothers and the fathers of the mentally retarded experienced significantly greater stress than respective parents of normal children did. In particular, the stress was significantly higher in the mothers than the fathers of these children in both groups. The difference in the levels of parental role stress experienced by mothers and by fathers was significantly bigger among those of the mentally retarded tnan among those of normal children. 3. No significant difference in the level of coping was observed between the mothers of both groups and the fathers of both groups. By contrast, the fathers revealed significantly greater scores in coping than the mothers in both groups. 4. General stress experienced by the fathers of the mentally retarded was different by health status, satisfaction with spouses, and the supports from their spouses. Health status, satisfaction with spouses, and monthly income Influenced parental role stress experienced by those fathers. Their level of coping was associated with their satis-faction with spouses and family life. 5. Of the mothers of the mentally retarded, the level of general stress was different by their health status, while parental role stress was related to the satisfaction with their spouses and the child's age. The level of coping among the mothers was different by the supports from their spouses. The above findings indicate that those parents of the mentally retarded did not take more coping strategies than those of the normal did, despite greater stress experienced among themselves. Hence, nursing intervention for managing stress should be given to those parents including fathers of mentally retarded children. Mothers of the mentally retarded, in particular, should receive high priority in planning nursing care, since they experience greater levels of both general stress and parental role stress than their spouses, which is most likey due to primary responsibility in child rearing given to them at home.

The purpose of this study was to investigate job stressors, job stress symptoms, and job performance of workers in fashion industry. The data were obtained from questionnaire completed by 529 workers who were employed in textile or clothing manufactures located in Seoul, Daegu, Busan, and Masan area. The SPSS package was used for data analysis which included frequency, mean, correlation, and factor analysis. Job stressors consisted of environmental related stressors, job related stressors(task characteristics and role characteristics) and organization related stressors(organization climate and career development). Most of job stressors were significantly correlated with job stress symptoms but their correlation coefficients were low. Among job stressors, quantitative work overload was found to be a major stressor. Workers in fashion industry appeared to evaluate their job performance relatively good. Also, it was found that behavioral and psychological symptoms were negatively correlated with job performance.
