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.

Objectives : This study was conducted to investigate the levels of psychosocial stress, job stress and their related factors among medical doctors practicing at local clinics. Methods : A survey using a self administered questionnaire was administered to 1,456 doctors practicing at private clinics via post for 2 months (2006. 1 - 2006. 3). Psychosocial stress, job stress, demographic factors, job related factors and health related behaviors were investigated. Among the eligible study population, the respondents were 428 doctors (29.4%). Results : The average scores of psychosocial stress and job stress were 2.19 and 3.13, respectively. The levels of psychosocial stress and job stress were statistically lower in older respondents, those who worked shorter or who were more satisfied with their job, and those with higher socioeconomic status. The level of psychosocial stress was related with smoking status, drinking status and exercise. The level of job stress was related with smoking status and exercise. In multiple linear regression analysis using psychosocial stress as a dependent variable, age, working hours per day, job satisfaction and perception on socioeconomic status were significant independent variables. In analysis using job stress as a dependent variable, age, working hours per day and job satisfaction were significant independent variables. Conclusions : Stress affects the doctor-patient relationship, productivity and overall health level of people. Therefore, it is important to manage and relieve the stress of doctors. It is suggested that more advanced studies on stress level and related factors and ways to improve the stress and health related behaviors of medical doctors should be conducted.

This study investigated relationships between the after-school extracurricular activities of kindergarten children and their daily stress. The subjects were 380 kindergarten children; they were interviewed regarding the degree of their daily stress. Their mothers completed questionnaires on the children's extracurricular after-school activities. Statistical analysis of the data showed that kindergarteners who participated in extracurricular after-school activities showed a higher degree of daily stress than children who did not. It was concluded that developmental appropriateness of extracurricular activities should be considered, and educational curricular and strategies to help children cope with daily stress due to excessive extracurricular activities should be prepared. Further research on this subject is recommended.

Objectives: The study was performed to examine the dietary behaviors and life stress of middle school students in the Gyeonggi area. Methods: A total of 580 middle school students (295 males, 285 females) in the Gyeonggi area participated in the study between July and August in 2011. The study was a questionnaire-based survey that included dietary habits, dietary behaviors, and life stress. Results: For dietary habits, the score for drinking milk was higher in male students than in female students, whereas the score for eating fruits was higher in female students compared to male students. There were significant differences in foods eaten and preferred under stress between male and female students. Male students showed significantly less changes in the number of meals, amount of meal intake, number of snacks, snack intake, frequency of overeating, and appetite during stress than female students. Life stress score of students largely came from academic factors, and female students showed higher stress levels in personal and surrounding environment factors than male students. Life stress score was significantly lower in students with high and moderate levels of dietary habits than in students with a low level of dietary habits. Total score for dietary habits and scores for eating adequate amounts of foods for each meal, considering a combination of food groups at each meal and eating green and orange vegetables, were significantly negatively correlated with life stress score. Life stress score was significantly negatively correlated with meal regularity and positively with the level of overeating. Conclusions: This study may provide basic information on dietary habits and life stress according to gender and the relationship between dietary behaviors and life stress of middle school students, and it suggests gender-based nutrition education programs to solve undesirable dietary habits and dietary behaviors in students with higher stress.

The purpose of this study was to investigate factors associated with coping responses in Korean public high school students. Methods: This study employed a descriptive survey research design. The sample included 263 high school students who responded to a self-report questionnaire. Variables included socio-demographic characteristics, health-related characteristics, academic stress, somatization symptoms, social support, and coping responses. Data were analyzed using descriptive statistics, t-tests, ANOVA, Pearson's correlations, and multiple regressions. Results: Participants, regarding their school life, reported moderate levels of academic stress ($M{\pm}SD=2.3{\pm}0.52$) and somatization symptoms ($M{\pm}SD=2.3{\pm}0.71$), and a relatively high level of social support ($M{\pm}SD=4.2{\pm}0.67$). All the variables were associated with the use of multiple coping responses. Active-cognitive coping ($M{\pm}SD=2.9{\pm}0.68$) was most frequently used, followed by active-behavioral coping ($M{\pm}SD=2.5{\pm}0.56$). and avoidant coping ($M{\pm}SD=2.3{\pm}0.75$). Significant relationships were found among the measured variables: positive relation between academic stress and somatization symptoms, but, negative between academic stress and both somatization symptoms and social support. Students who had higher stress and more somatization symptoms were more likely to use avoidant coping than the others. In multiple regression analysis, while factors associated with each coping response differed, gender appeared to be a significant factor in all methods. Variables included in the final model explained 27% of the variance in avoidant coping (F=11.40, p<.001). Conclusion: Based on the study results, schools should provide tailored educational programs to help high school students reduce multisource stress and somatization symptoms at school and cope with them in more active and effective ways.

The main purpose of this study was to examine the mediating roles of mothers' psychological well-being and support/control in the relationship between maternal child-related stress and adolescents' school adjustment. Participants were 389 3rd grade middle school students and their mothers. Mothers completed questionnaires about child-related stress and psychological well-being. Adolescents completed scales of maternal controlling/supportive parenting and school adjustment. Results indicated that a direct effect of mothers' child-related stress on adolescents' school adjustment was not significant. However, mothers' psychological well-being and support/control mediated the relations between child-related stress and adolescents' school adjustment. A higher level of child-related stress in mothers was associated with a lower level of psychological well-being, followed by a lower level of adolescents' school adjustment. Mothers who reported a higher level of child-related stress tended to be less supportive and more controlling, which led to a lower level of school adjustment. These findings suggest the need for considering both maternal characteristics and parenting in explaining adolescents' school adjustment.

For cam and roller-follower contacting surfaces, the effect of tangential loading on the subsurface stress field at an elaso-hydrodynamic lubrication condition has been studied numerically. As tangential load increases, the subsurface stress field extended more widely to the direction of the tangential load. The positions of the maximum shear stress and the maximum effective stress are getting closer to the surface with the increasing tangential load. The tangential load at the elasto-hydrodynamic lubrication condition is of little consequence to the subsurface stress field.

This paper introduces a rapid measurement technique for the stress-optic coefficient, using terahertz time-domain spectroscopy. First we propose a design combining a four-point bending device with a scanning stage to streamline the loading process. Then we detail the measurement principle and outline the signal-processing algorithm. The experiments are carried out on Al₂O₃, a representative ceramic material. The experimental data reveal that the refractive index of Al₂O₃ exhibits a linear decrease with increasing stress. This work supplies an efficient method for stress measurement rooted in the stress-optic effect.
