The reliable determination of the stress intensity factors for cracks in bolted Joints is needed to evaluate the safety and fatigue life of them widely used in mechanical components. The weight function method is an efficient technique to calculate the stress intensity factors for various loading conditions using the stresses of an uncracked model. In this paper the mixed-mode stress intensity factors for cracks in bolted joints are obtained by weight function method, in which the coefficients of weight function are determined by finite element analyses far reference loadings. The effects of the magnitude of clearance and factional coefficient on the stress intensity factors are investigated.

Most of previous studies on civil servants' stress factors and job satisfaction have been focused on low job satisfaction caused by stress from role relations and human relations. In case of fire officers, however, their stress is expected to be influenced by their unique job characteristics such as risk, urgency, stand-by, and shift. Thus, this study divided fire officers'stress factors into job-related factors (risk, urgency, stand-by, alternation) and role-related factors (role conflict, role ambiguity, role overload), and empirically analyzed how these factors affect their job satisfaction. According to the results of this study, fire officers' job characteristics and their roles in the organization had a significant effect on their job satisfaction. Particularly, among the job-related factors, urgency and stand-by had a positive effect on job satisfaction, and among role-related factors, role conflict and role overload had a negative effect on job satisfaction. In addition, fire officers' stress and job satisfaction were significantly different according to their job (fire fighting, rescue and first aid, fire administration, others), and according to their workplace (fire fighting headquarters, fire station, 119 safety center).

Purpose: The purpose of this study was to identify the factors influencing Symptoms of Stress among hospital staff nurses. Method: Data was collected by questionnaires from 249 hospital staff nurses in three General Hospital. The data were analyzed using descriptive statistics, pearson correlation coefficients, and stepwise multiple regression. Results: The score of the symptoms of stress showed a significantly positive correlation with the score of work stress(r=.22, p=.00). The symptoms of stress showed a significantly negative correlation with the score of social support(r=-.28, p=.00), self efficacy(r=-.31, p=.00), and hardiness(r=-.24, p=.00). The most powerful predictor of symptoms of stress was social support and the variance explained was $16\%$. A combination of social support, ways of coping, and work stress account for $32\%$ of the variance in symptoms of stress among hospital staff nurses. Conclusion: This study suggests that social support, ways of coping, self efficacy, hardiness, and work stress are significantly influencing factors on symptoms of stress among hospital staff nurses.

Purpose: We wanted to examine the degree of employment stress that university seniors suffer and to find the factors affecting on this employment stress. Methods: The subjects were 250 university seniors in Seoul and Gyeonggido, and the data were gathered by using questionnaires that were administered from September to October in 2004. The data were analyzed with the SAS program by t-test, ANOVA, Pearson correlation coefficient and stepwise multiple regression. Results: The mean score of the respondents' total employment stress was 96.5 point out of 200. Their sub-factors of employment stress was 2.0 out of 4.0 for 'academic', 1.9 for 'personality', 2.1 for 'school environments' and 1.9 for 'home environments'. The degree of the seniors' employment stress from such things as their majors, their available jobs in the future, leaves of absence from school, the employment status, and the number of semesters within the leave was found to have significant differences. The major factors affecting on the employment stress were those related to personality stress and majors of the students, and these were 92.7% of the total stress. Conclusion: This study suggests the necessity of intervention or counseling with consideration being given to seniors' employment stress and the other symptoms like depression for improving the health of university seniors.

Objectives : This study aimed to determine the effects of stress coping type on self-esteem and satisfaction with life in dental hygiene students. In particular, an attempt is made to determine the effects of sub-factors of stress coping type on self-esteem and satisfaction with life, get a better understanding of self-esteem and satisfaction with life for dental hygiene students, and provide basic data in developing a program that can identify, prevent, and control the problems with stress for dental hygiene students. Methods : This is descriptive correlation research to determine the relations between self-esteem and stress coping type in dental hygiene students. 212 dental hygiene students at colleges in Ulsan Metropolitan City were asked to complete a self-administered questionnaire from June 10 to 20, 2013; then, 209 copies were used in analysis, with the exception of 3 copies which were excluded from recording. Results : Self-esteem and satisfaction with life were positively affected by active stress coping but were negatively affected by passive stress coping. As for such sub-factors of stress coping type as problem-focused coping, pursuit of social support, emotional relief coping, and hopeful thinking, the sub-factors of active coping type also positively affected self-esteem and satisfaction with life. Self-esteem interacted with the sub-factors of stress coping type and satisfaction with life. Conclusions : Since stress coping type was found to be a factor affecting self-esteem and satisfaction with life for students, the results of this study are expected to be used as basic data in developing a program that can help them cope actively with stress.

Objective : To investigate the sources, extent and related factors in South Korean doctors. Methods : The study subjects were 934 doctors in Taegu, Kyungpook Province, Korea(540 independent practitioners, 105 employed at hospitals and 289 residents in training). Information concerning job stress was obtained using a 9-item questionnaire. Information regarding related factors such as demographic characteristics(age, sex, marital status), perceptions on the socioeconomic status of doctors and working conditions(work time, on-call days per week) was also obtained by self-administered questionnaire during April and May, 2000. Results : Major sources of job stress included clnical responsibility/judgement factor, patient factor and work loading factor. The job stress score of residents was the highest among three groups. The score was lower in older doctors. The score was low among those who thought doctors' socioeconomic status was not good. The longer the work time, the higher the job stress score was. Multiple regression analysis was conducted to control for the mutual influence of independent variables. In regression analysis, the score of residents was higher than practitioners. Work time and socioeconomic status perception had negative effects on job stress score. Conclusion : The average job stress score of the doctors was high. Age, work type, working conditions and perceptions of socioeconomic status were found to besignificantly related to job stress score. Although the job stress of doctors is somewhat inevitable due to the nature of the doctor's job, control of work time, development of coping tools and other intervention methods are needed to reduce job stress of doctors. Further studies are required to understand the characteristics of iob stress and reduce the job stress of doctors.

Stress is a primary health promotion issue in worksite research because psychological distress is closely related not only to workers' health status but also to their job performance. This study identified the significant health behaviors affecting workers' job-related stress in Korean manufacturing industry with the national survey data conducted by the Korean Occupational Safety and Health Agency in 2003. A total of 7,818 factory workers in 1,562 manufacturing companies participated in the Korean nation-wide occupational health survey and 3,390 workers answered that they had any stressors in their workplace among the 7,818 workers finally participated in the analysis. Participants were selected by the stratified proportional sampling process by manufacturing industry classification, company size, and company locations (8 metropolitan and 8 non-metropolitan regions) in Korea. Trained interviewers visited the target companies and interviewed the factory workers randomly selected in each company. Smoking, drinking, weight control, exercise, sleeping, break time at work, and perceived fatigue were included in the health behavior construct. Stress symptoms was consisted of physical and psychological stress with 8 items. All survey responses were anonymously coded into the SPSS statistical program and testified using stepwise multiple regression analysis. Male workers were 73.5% and the 30s were 40.0% among the age groups. The married and the high school graduate were majority with 52.1% and 61.8% each. Current smokers were 44.7% and More than 50% of the participants drank alcohol sometimes. No exercise group was 59.3% and the participants who dissatisfied with their daily sleeping hours were 43.5%. In t-test and analysis of variance, the significant general characteristics associated with physical and psychological job stress were young age (p<0.001), single marital status (p<0.001), and short working period at the present company (p<0.001). The health behaviors related to physical job stress were current smoking, weight change during the past one year (p<0.001), weight control effort (p<0.001), exercise (p<0.001), daily sleeping dissatisfaction (p<0.001), break time, and perceived fatigue (p<0.001). All 10 health behavior factors were significantly associated with psychological job stress (p<0.05). Weight change, weight control effort, exercise, daily sleeping dissatisfaction, little break at work, and high perceived fatigue were significant factors affecting job stress. Daily sleeping dissatisfaction, little break at work, little exercise, weight change for the past one year and young age were selected as the significant health behavior and general factors affecting physical job stress symptoms in stepwise multiple regression analysis. The five factors explained 18.9% of the physical stress score variance. Six factors were selected as the significant health behaviors affecting psychological job stress: daily sleeping dissatisfaction, little exercise, frequent drinking alcohol, high perceived fatigue, little break at work, and little weight control effort. The six factors explained 10.6% of the psychological stress score variance.

This study analyzed the effect of workers' socio-psychological burden factors on musculoskeletal disorders. A survey was conducted targeting office and field workers in the Seoul metropolitan area. Analysis was performed using the results of 357 surveys out of 400 surveys. The analysis results were derived as follows. First, the socio-psychological burden factor did not show statistically significant results for musculoskeletal disorders. Second, it was found that job stress factors also had a positive effect on musculoskeletal disorders. Third, social psychological burden factors were found to be more positive than office workers than field workers. Fourth, there was a statistically significant correlation between job stress and musculoskeletal disease risk scores. From the above results, job stress factors affect musculoskeletal disease risk factors (work frequency, pain level, and duration) and the increase in musculoskeletal disorders and the number of accidents.
