The thermal stress intensity factors for interface cracks of Griffith and symmetric lip cusp types under vertical uniform heat flow in a finite body are calculated by boundary element method. The boundary conditions on the crack surfaces are insulated or fixed to constant temperature. The relationship between the stress intensity factors and the displacements on the nodal point of a crack tip element is derived. The numerical values of the thermal stress intensity factors for interface Griffith crack in an infinite body and for symmetric lip cusp crack in a finite and homogeneous body are compared with the previous solutions. The thermal stress intensity factors for symmetric lip cusp interface crack in a finite body are calculated with respect to various effective crack lengths, configuration parameters, material property ratios and the thermal boundary conditions on the crack surfaces. Under the same outer boundary conditions, there are no appreciable differences in the distribution of thermal stress intensity factors with respect to each material properties. But the effect of crack surface thermal boundary conditions on the thermal stress intensity factors is considerable.

Stress is the main source of a human error or can potentially contribute to it. Recently, the rate of accidents which is associated with human factors among the total aircraft accidents is showing a tendency of gradual increase. In order to prevent the accidents related to human factors, stress mitigation of the mission personnel is highly required. In this study, a 'stress cognitive alteration' technique, which is one of the stress relief methods, is applied to the Air Force pilots to verify if the technique is effective in reducing stress. The 'stress cognitive alteration' technique is comprised of two parts: a positive function of stress and a process to positively alter the physical, psychological response to stress. As a result of the application, it is found that this technique has an effect of reducing stress of the pilots under a relatively high level of stress.

Purpose: The purpose of this study was to measure the level of stress and symptoms of stress (SOS) in soldiers and to investigate the factors that have effects on the symptoms of stress. Methods: Data was collected from soldiers of two military units located in north Kyounggi-Do from August 2 to 9, 2006 by using the survey instruments. Results: This research found that the average values on the level of stress and symptoms of stress were about $2.53{\pm}0.60$ (range 1.00-4.35) and $0.95{\pm}0.55$ (range 0.04-2.83), respectively. The things which affected symptoms of stress, according to this study, were the external factors in the military (${\beta}=.28$, p<.001), role and relation factors (${\beta}=.21$, p<.001), work factors (${\beta}=.15$, p=.01) and passive coping styles (${\beta}=.19$, p<.001). These variables explained 28% (F=36.68, p<.001) of the variance of the total symptoms of stress. Conclusion: This study suggests that soldiers need to under go stress management.

Purpose: This study was performed to identify workers' Job stress status and to analyse the influencing factors. Method: Data were collected from 456 workers with Korean Occupational Stress Questionnaire Short Form(KOSQ SF) and analysed using descriptive statistics, t-test, ANOVA. Results: Total job stress status of men was slightly lower than Korean workers' standard. In case of women, the score of total job stress was lower than Korean workers' standard. The most significant influencing factors to stressors were insufficient sleeping time and self cognitive bad health condition. Among seven domains of job stressors, job demand was affected by 8 characteristics. Conclusion: This study indicated that workers' job stress level were various by their characteristics except workplace size. The development of stress management programs by types of industry is required. On the base of the model program, planning of customized program for every company or employee is required. High job demand, insufficient job control, insufficient sleeping time, bad health condition are the key factors of workers' job stress in this study. The change of workers' health behavior with supportive environment is essential to stress management program. More researches for adding physical environment domain to KOSQ SF are expected.

The purpose of this study was to discuss the difference of stress by the grade, examine the relationship between characteristics and main stress, and to investigate the effect of the National Examination of Registered Nurses on stress by using the stress self-rating scale targeting university nursing students (n=314), The stress self-rating scale consists of three subscales: stress responses, stressors and coping parts, such as perceived social support and a sense of humor. The data were analyzed by descriptive statistics, t-test, Pearson's correlation coefficient and regression analysis. The results showed that passing the National Examination of Registered Nurses was the first problem among the stressors. Stressors of the living factors and nursing factors, and subjective stressors of the surveyed nursing students were the highest among the senior students, but stressors of nursing factors increased according to the grade of the nursing students. Perceived stress responses were high in psychological responses of other aspects, and perceived stress responses increased according to the grade (p<.001). Senior students had a high weight of perceived stress responses (problem-focused, emotion-focused). and active and negative coping modes. Significant factors that explained the stressors were coping mode(r=.62-82. p<.01) and cognition(r=.19. p<.01). including the social support. These findings suggest that social support was very important for seniors. and that we have to develop approaches to decrease stress according to the student grade for nursing education process.

For the purpose of disclosing the mental health status as well as its stress factors of female workers in industry, a questionaire survey was carried out on 283 female workers, namely. 134 of a service industry(department store) in seoul and 149 of a manufacturing industry(food) in Kyunggi-do district from 24 to 29 January, 1994. The result were as follows : 1. The mean scores of poor mental health indicator showed no significant difference between service industry and manufacturing industry, while the mean scores of good mental health indicator showed a significant difference between those two industries. 2. The mean scores of work stress as social stress factors showed a significant difference between service industry and manufacturing industry. However, no significant difference was observed between the mean scores of personal stress factor between those two industries. 3. In general, the work stress factor was more significantly contributed by marital status, while the social stress as well as the personal stress factor were contributed more by monthly income. 4. The major contributing factor to the poor mental health was the personal stress factor in general, followed by the work stress factor. However, the weight of these two stress factors was reversed according to the type of industries.

Stress is a common risk factor for health and is associated with the endocrine gland and immune system. Studies on the association between stress and biochemical factors have been conducted worldwide, but studies on the association have been rare in South Korea. Therefore, the aims of this study are to analyze the relationship of stress with demographic information and biochemical factors for domestic adults and derive risk factors for stress. For data analysis, stress and normal groups were analyzed using binary logistic regression. In both men and women, age and average daily sleep time during the weekday were highly associated with stress, and the depression score (Patient Health Questionnaire-9) was also highly related with stress. In women, white blood cell levels were highly associated with stress, and in men, red blood cell levels were highly related with stress. These findings will contribute to the prevention of stress and the national health in the future.
