The outcomes of solution annealing and stress corrosion cracking in cold-worked 316L austenitic stainless steel have been studied using x-ray diffraction (XRD) and the slow strain rate test (SSRT) technique. The good compatibility with a high-temperature water environment allows 316L austenitic stainless steel to be widely adopted as an internal structural material in light water reactors. However, stress corrosion cracking (SCC) has recently been highlighted in the stainless steels used in commercial pressurized water reactor (PWR) plants. In this paper, SCC and inter granular cracking (IGC) are discussed on the basis of solution annealing in a chloride environment. It was found that the martensitic contents of cold-worked 316L stainless steel decreased as the solution annealing time was increased at a high temperature. Moreover, mode of SCC was closely related to use of a chloride environment. The results here provide evidence of the vital role of a chloride environment during the SCC of cold-worked 316L.

This study was carried out to measure the degree of work-related stress and to identify factors influencing the excessive stress among clinical physical therapists. One thousand and five physical therapists surveyed nationwide met the established criteria for inclusion in the study. The respondents were an average age of 27.1 years, $34.5\%$ were married, and $61.2\%$ were female. Most of the respondent $(48.1\%)$ worked in local clinics. The average stress score was 50.9. Analysis-of-variance test demonstrated significant difference in the degree of stress among treatment facilities. There was a significant relationship between treatment facilities (general hospital, local hospital, clinic), number of patients treated per day, job satisfaction, low back pain and work-related stress, respectively. Work-related stress was unrelated to matters of sex, marital status, education. Hospital administrators, physical therapydirectors, directors, and individual therapists should work within their organizations to reduce work stress and its detrimental effects. Further research is necessary to investigate preventive measures to decrease the work-related stress.

Objectives: The aim of this study was to investigate the association between work-related stress and depressive symptoms among dental hygienists. Methods: This survey of dental hygienists was conducted in Gyeonggi province, South Korea. Total of 198 dental hygienists were interviewed in 2014. The occupational stress was evaluated by depression symptoms, which was assessed by the Beck Depression Inventory Scale. To estimate the odds ratio with 95% confidence intervals, logistic regression model was used. Results: Depressive symptoms were reported 46.0%(n=91) among dental hygienists. We found that the work-related stress increased with age, smoking(OR=5.16; 95% CI 1.73-15.3), and those who had the poor perceived health status(OR=4.22; 95% CI=1.50-11.86) was associated with the risk of depressive symptoms. After controlling potential confounders, such as dental hospital(OR=11.05; 95% CI=1.02-118.9), 5-7 years time since first employment(OR=0.15; 95% CI=0.03-0.89), and the group with the high job stress(OR=2.84; 95% CI=1.22-6.79) showed higher risks of depressive symptoms than did no depressive symptoms. Conclusion: Our findings suggest that the risk of depression appears to be related to age, smoking, self-reported health status, type of dental facility, years of practice and the stress of job.

The purpose of this study was to evaluate job stress factors of school food service nutritionists according to the number of years they have worked. The subjects of this survey included 125 nutritionists (69 from full-time employees and 56 from part-time nutritionists) from elementary school, middle school, and high school in the Gangwon area. The results showed that stress related to duty was the top job stress factor, followed by environment-related stress, personal stress, organization-related stress and stress caused by human relations. In terms of the degree of stress, part-time nutritionists have more stress compared to full-time nutritionists. This was especially true for nutritionists that had been employed for one year. In this case, the degree of stress was much higher than long time employed nutritionists. In terms of how to deal with job stress, school nutritionists eliminated stress directly (with direct countermeasures). In order to deal with stress, workers expected stable employment such as pay (wages), promotions, etc. In particular, part-time school nutritionists had stronger expectations. When correlation between job stress factors were examined, environment-related, duty-related, organization-related, human relations-related and personal stress were all shown to be mutually related.

The purpose of this study is to examine the job satisfaction and the job stress of British child care teachers. Respondents, including childminders, were 137 British child care teachers who worked in nursery school, day nursery, creche, and playgroup. In the survey on the job satisfaction of British child care teachers, they were asked to answer two items. In the survey on their job stress level, they were required to rate their job-related stress levels on a 5 point scale of 'Job Stress scale' by Davis et al(2003). The results indicated: firstly, the British child care teachers are much satisfied with their job and have the low level of job stress. Secondly, their job satisfaction depends on who runs the child care facilities, what position they have in the centers, how long they work for child care, what qualifications they have. The levels of their job stress depend significantly on their present position in the centers. Thirdly, the job satisfaction of British child care teachers is explained about 27%, is related to their performing of daily routine, their age, the management of child care centers and qualifications of the teachers.

Background: This study aimed to identify the impacts of job stress and cognitive failure on patient safety incidents among hospital nurses in Korea. Methods: The study included 279 nurses who worked for at least 6 months in five general hospitals in Korea. Data were collected with self-administered questionnaires designed to measure job stress, cognitive failure, and patient safety incidents. Results: This study showed that 27.9% of the participants had experienced patient safety incidents in the past 6 months. Factors affecting incidents were found to be shift work [odds ratio (OR) = 6.85], cognitive failure (OR = 2.92), lacking job autonomy (OR = 0.97), and job instability (OR = 1.02). Conclusion: Patient safety incidents were affected by shift work, cognitive failure, and job stress. Many countermeasures to reduce the incidents caused by shift work, and plans to reduce job stress to reduce the workers' cognitive failure are required. In addition, there is a necessity to reduce job instability and clearly define the scope and authority for duties that are directly related to the patient's safety.
