Background: Both the rapid concentric and eccentric contractions during exercise repeatedly impose excessive stress on muscle tissue. The hamstring muscles are very susceptible to injury due to the tensile stress. Various interventions are currently being undertaken to prevent strain injury before exercise. Stretching is the most common method and is known to have a positive effect on flexibility and muscle performance. However, relatively few studies have investigated the potential negative factors of stretching. Objects: The purpose of this study was to examine changes in pain following the different intensity of the stretching and types of physical stress. Methods: The subjects were divided into three groups based on the intensity of stretching: 100% (S100), 75% (S75), and 50% (S50) of the measured force at the point of discomfort in static stretching and 100% (P100), 75% (P75), and 50% (P50) of the maximum voluntary isometric contraction in Proprioceptive Neuromuscular Facilitation (PNF) stretching. The pain individual subjects perceived after stretching was measured via a Visual Analog Scale (VAS) and compared between the groups Results: Despite the decrease in the intensity of static stretching, no decrease in VAS value was observed. In PNF stretching, a significant decrease was observed at P50 compared to P100. S100 was significantly higher than P75 and P50. Conclusion: Previous studies have shown that PNF has a superior or the same effect on flexibility in comparison with static stretching. This effect was maintained even in moderate intensity. PNF stretching performed under moderate rather than high intensive static stretching, which causes pain and discomfort, might be recommended in clinical settings.

Purpose: This study investigated the dietary behavior of experienced shiftwork nurses and aimed to identify factors related to dietary behavior. Methods: This study was a secondary analysis based on the Shift Work Nurses' Health and Turnover study (2018-2021) among Korean nurses. In total, 247 experienced (>12 months) shiftwork nurses were included in this study. The participants' dietary behavior, depression, level of occupational stress, fatigue, physical activity, and general characteristics were measured. Descriptive statistics, Pearson correlation coefficients, independent t-test, one-way analysis of variance, the Kruskal-Wallis test, and multiple regression analysis were conducted. Results: The dietary behavior score of the participants using the Mini-Dietary Assessment Index was 29.35±5.67. Thirty percent of the participants were depressed, the participants experienced moderate occupational stress, and 74.1% of the participants engaged in an inadequate amount of physical activity. The factors influencing shiftwork nurses' dietary behavior were having child(ren) (β=.16, p=.027), depression (β=-.13, p=.032), level of occupational stress related to occupational climate (β=-.13, p=.035), and an inadequate amount of physical activity (β=-.17, p=.006). These factors explained 10.4% of the variance in experienced shiftwork nurses' dietary behavior scores. Conclusion: Experienced nurses with child(ren) tended to have healthier diets. However, a higher level of occupational stress related to occupational climate, depression, and engaging in an inadequate amount of physical activity were associated with a higher risk of having an unhealthy diet. Therefore, strategies are needed to encourage physical activity and alleviate adverse occupational climate and depression among experienced nurses.

In the perspective of industrial health management, it is important for the employee to decrease their job stress, to improve their productivity and quality of labor. In this study, the job stress, and it's influence on PWI(Psychosocial Wellbeing Index) were investigated by the questionnaire survey of 138 industrial workers who had studied assistive technology in college. The contents of questionnaire consist of the demographic characteristics, job-related characteristics, job stress and psycho-social stress. We evaluated job stress by KOSS-SF(Korean Occupational Stress Scale-Sort Form) and psychosocial stress by PWI-SF(Psychosocial Well-being Index-Short Form). To analyze the results, we evaluated the exposure level of KOSS and PWI by demographic characteristics and job-related characteristics using significance tests. Also, we estimated the relationship among demographic characteristics, job-related characteristics, job stress and psychosocial stress, using correlation analysis. As a results, all workers were found to be in a group under the high risky stress. It showed that the scale index of female's job non-autonomy and pwi were much larger than those of male's. Therefore, to guarantee job autonomy of female workers should be more emphasized, to improve their working environment. Job type had significant relationships with many job stress category; physical environment, job demand, job instability and organization culture. Regarding pwi, the scale index of the workers who is in charge of the civil service such as contacting the disabled and the aged in person, were much larger than that of the other workers. Accordingly, the job stress management program including physical environment, job demand, job instability and organization culture, should be suggested, to decrease the stress of the workers in charge of the disabled and the elders service. The strongest predictors of pwi was organization system through maximum positive relations between organization system and pwi. Therefore, it indicates that improvement of organization system such as a fair merit rating, a manpower supply, demand plan and department cooperation is urgently needed to reduce pwi.

The purpose of this study is to identify the effects of lifestyle, study stress and training stress on health status, and provide fundamental data for health management of university students majoring in physical education. In this study, 149 students participated and they were surveyed demographic characteristics, lifestyle, Maslach burnout inventory (student stress inventory), training stress inventory, and Mibyeong index. Height and weight were measured for calculating BMI. For statistical analysis, Student t-test, ANOVA test, chi-square test, correlation analysis, and multinominal logistic regression test has been used. There were differences between Mibyeong groups according to digestion status, smoking for female students and quality of sleeping for both male and female students. Study stress and training stress also affected to health status. Cynicism among study stress categories and all categories among training stress showed differences between sex. Correlation analysis and logistics regression analysis was used to estimate related factors of health status after adjusting for sex and age. Based on logistics regression analysis, quality of sleeping affected to Mibyeong 1 group and quality of sleeping, smoking and digestion status affected to Mibyeong 2 group. Among training stress category, dissatisfaction with game result and skills and lack of leisure time were affected to both Mibyeong 1 and 2 group. This study suggests that lifestyle, study stress and training stress might be significantly associated with university students majoring in physical education. Through managing those influence factors, health status of students could be improved.

Purpose: This study was done to investigate the prevalence of job stress and musculoskeletal symptoms, and to identify the factors that affect work-related musculoskeletal symptoms of the 119 Emergency medical technicians (EMT). Method: From August 26 to September 10, 2010, the data were obtained from 456 EMT working in Daejeon city or Choongnam province. For data analysis, descriptive statistics and multiple logistic regression were performed using SAS version 9.1. Results: Physical environment, job demand, interpersonal conflict, and occupational climate were stressful to 119 EMT. The prevalence of musculoskeletal symptoms of female EMT was higher than those of the male EMT's. After gender and age were adjusted, there ware significant relationships between musculoskeletal symptoms and some risk factors including occupational class, hours of intensive musculoskeletal use, previous injury or work-related injury, physical burden, and job stress. Overall, a higher degree of job stress increased musculoskeletal symptoms. Conclusion: Job stress is a major cause of musculoskeletal symptoms. To prevent and manage musculoskeletal disease of 119 EMT, there is a need to develop a management program for musculoskeletal symptoms to reduce occupational stress, considering gender differences.

Purpose: The purpose of this study was to investigate occupational stress and fatigue level of neonatal nurses and to assess relationship between the two of them. Methods: Subjects were 109 neonatal nurses working at 2 university hospitals and 9 women's hospitals in D city, and the data were analyzed using descriptive statistics and binary logistic regression analysis by the SPSS/WIN 15.0. Results: The mean score of nurses' occupational stress level was 3.22, and the highest was 'night shift' among the 7 subcategories, and fatigue level was 62.0, and the highest was physical fatigue in configuration field. In logistic regression analyses, 'heavy workload' and 'inadequate physical environment' led to most occupational stress. Conclusion: In addition to significantly higher levels of occupational stress of neonatal nurses, the cumulative fatigue also resulted in decreased quality of nursing, job satisfaction and nursing productivity; therefore, appropriate number of nurses and improvement of work environment is necessary. Furthermore, to reduce the occupational stress and fatigue, we should try to develop adequate clinical guidelines and intervention strategies and apply them in neonatal care unit.

Objective: This study is based on a parallax design before and after a non-equivalent control group to examine the effects of laughter therapy on the anxiety, depression, and stress in patients with cancer admitted to a nursing hospital. Design: A randomized controlled trial. Methods: Data collection was conducted on 34 patients who agreed to participate in the study among patients admitted to E Cancer Hospital from September to November 2018. Laughter treatment interventions were performed three times a week for 50 minutes each and a total of eight times. In this study, a tool developed by Spielberger was used to measure state anxiety, a tool developed by Beck was used to measure depression, and the Perceived Stress Scaled eveloped by Cohen was used to measure stress. Results: Anxiety was significantly lower in the experimental group than in the control group (F=10.74, p=0.003). Depression was lower in both the experimental group and the control group that did not participate in the laughter therapy intervention and was not significant (F=0.58, p=0.451). Stress was significantly lower in the experimental group than in the control group (F=4.36, p=0.045). Conclusions: The results of this study suggest that laughter therapy has a positive effect on reducing anxiety and stress in patients with cancer admitted to nursing hospitals.
