It is well known that osteoblasts and osteoc1asts playa key role in bone metabolism. They involve in osteoformation or bone destruction which are ragulated by various factors such as thyroid hormone, parathyroid hormone, estrogen, growth factor and cytokine. Recently, it is demonstrated that oxidative stress is one of pathological factors in bone metabolism, but it is left unknown about mechanism between oxidative stress and bone metabolism.(omitted)

An analysis program for the evaluation of pressure vessel integrity under pressurized thermal shock (PTS) is developed. For given material properties and transient history such as temperature and pressure, the stress distribution is calculated and then stress intensity factors are obtained for a wide range of crack sizes. The stress intensity factors are compared with the fracture toughness to check if cracking is expected to occur during the transient. Using this program a round robin problem of PTS during a small break loss of coolant transient has been analyzed as a part of the international comparative assessment study. The allowable maximum reference nil-ductility transition temperatures are determined for various crack sizes.

Purpose: The purpose of this research was to find out factors affecting job stress and job satisfaction of nurses working at the welfare centers. Methods: This study was performed with 140 nurses who were working at or had retired within 1 year from general welfare centers in Seoul during the period from March 29 to February 29 2004. We used a questionnaire asking about general characteristics. work characteristics. stress factors and job satisfaction. We analysed 103 subjects who replied to the questionnaires. Results: The mean job stress level was 2.84 out of 5 and. as for the sub-factors of job stress. income was 4.19, career development 3.69, service environment 3.26 and support system 1.90. The mean job satisfaction level was 3.32 out of 5 and. as for the sub-factors of job satisfaction, job control was 3.58, efficiency of organization 3.27, job burden and responsibility 2.92 and role ambiguity 2.25. When the nurses' job stress was compared according to their general and work characteristics. stress level was significantly high in nurses who had a short experience. were working at the department of senior welfare center. or were the only staff at their workplace (p <0.05). In addition. satisfaction level was significantly high in nurses who were working at the department of senior welfare center and medical welfare team. were the only staff at their workplace or had a heavy work load (p<0.05). According to the results of multiple regression analysis. job stress level was influenced by age ($R^2$=0.212. p<0.01). and job satisfaction level by the number of staffs and work' load ($R^2$=0.272. p<0.1). Conclusions: The results of the study suggest that good atmosphere should be made up to communicate between the departments at the workplace in order to lessen job stress and enhance job satisfaction of nurses working at welfare centers. In addition. role division and job duties among special staffs should be reviewed in order to achieve high efficiency in performing job duties.

The purpose of this study was to identify the effect of the Stress Management Education Program (SMEP) on the nurses stress and stress management ability, and to identify the main factors affecting them. The subjects were 72 nurses who participated in the In-Service education program of the Jin-Ju District, Kyeong-Nam Branch of the Korean Nurses Association during the period from Oct. 1 to Nov. 30, 1985. The book of“The stress management education program”was developed by the investigators. With this book, we executed the 1st education through the lecture & showing an example, After 15 days from the 1st education, we mailed a reminding booklet to the individuals. (2nd education). Then, we mailed a questionnaire on 15th day from the 2nd education. Before and after the SMEP We measured the stress management ability & stress, and identified the affecting factors. Findings of this study are as follows ; 1. The 1st hypothesis that“the SMP will increase the. knowledge about the nurses' stress management”was supported (t= -6.60, p <.001) 2. The 2nd hypothesis that“the SMEP will increase the nurses' practice about the stress management”was rejected. 3. The 3rd hypothesis that“the SEMP will decrease the nurses' stress”was rejected. 4. The 4th hypothesis that“the higher the know-ledge about the stress management, the lower the nurses' stress”was rejected. 5. The 5th hypothesis that“the higher the degree of the practice about the stress management, the lower the nurses' stress”was supported. (r= - .2859, p<.05). 6. There were significant correlations between the knowledge about stress management and age (r= -.3717, p<.01), between the knowledge about stress management and the period of her work. (r= -.2897, p<0.5). There was significant difference in the knowledge about stress management between those who had married and those who had not. (t=2.82, p<.01) 7. There was significant difference in the practice about the stress management between those who had religion and those who had not. (t=2.7, p< .01) 8. There was significant difference in the stress according to the type or work. (t=6. 127, P <.05) There was significant correlation between the stress and supportive system. (r=-.2647, p<.05).

Purpose: This study was conducted to examine the influencing factors of social support, self efficiency and depression among the hearing-impaired and physically disabled on their job stress. Methods: The data were collected from Jan.1 to Aug. 30, 2010 from 151 disabled workers. The instruments for this study were the Korean Occupational Stress Scale (KOSS), Social Support Scale, General Self-Efficacy Scale and Beck Depression Inventory-Korean Version (K-BDI). The data were analyzed using t-test, Pearson correlation coefficient and multiple regression with the SPSS/WIN 18.0. Results: The physically disabled show higher social support (t=0.284, p= .001) and self efficacy (t=0.165, p= .024) but lower in depression (t=0.789, p<.001) than the hearing-impaired. There are negative correlation between job stress and social support, job stress and self efficacy but a positive correlation between job stress and depression. These three factors explained 42.9% of the variance in job stress. Conclusion: Social support and self efficacy have positive impacts on job stress but depression has negative impact.

Purpose The purpose of this study was to investigate the factors affecting the users' stress and using reluctant intention to use social network service(SNS). This study especially focused on stress of SNSs' user. Because SNS has led to negative effects such as invasion of privacy, addiction and social overload recently. In addition, adverse effects of SNS had caused SNSs' user to feel stress and fatigue. Design/methodology/approach This study developed hypotheses to empirically examine the factors that affect SNS users' stress and using reluctant intention. In order to verify research hypotheses, this study collected data from 362 users who currently use the SNS in Korea. Further, we used the smartPLS analysis. Findings The results of this study are as follows; First, reputation perception, unwanted relation burden, privacy concern, information overload and interaction overload had a significant positive effect on SNS users' stress. But international influence had no significant positive effect on SNS users' stress. Second, SNS users' stress had a significant positive effect on using reluctant intention. The results of this study provides theoretical foundations on the research for dark side of SNS and implies that SNS providers are in need of exerting an effort to minimize the negative aspects.
