  • According to the Statistics Korea, in 2011, people over the age of 65 years old accounted for 11.8% of Korea's population. This number is expected to rise to 15.0% by 2019, making Korea an "aged society". As age increases, physical ability degrades to the point that the workload must be adjusted limitations. However, workloads are given regardless of workers' ages or abilities. In addition, a decline in work efficiency due to aging also increases the risk of work-related injuries. Furthermore, the cases of stress related diseases along with musculoskeletal disorders(MSDs) rise as main factors of industrial disasters and excessive job stress gives negative influence not only on mental health but also on physical health so that job stress becomes a hot issue as a main cause of work ability falloff and turnover. The purpose of this research is to examine how the sociodemographic characteristics, MSDs symptoms and musculoskeletal workload of workers in the manufacturing industry of automobile parts influence work ability and job stress. As a result of the research, job ability showed significant differences statistically according to age, working year, sex, marital status and musculoskeletal workload and job stress showed significant differences statistically according to age, working year, marital status and musculoskeletal workload. In addition, it showed that as the worker's job ability decreases, job stress increases.

  • Changes in viscosity and dynamic theological properties of Job's-tears were measured by Bohlin dynamic tester as a function of moisture, and measurement was performed within a linear viscoelastic range. The result of the shear stress vs shear rate of Job's-tears at different moisture contents $(50{\sim}75%)$ was applied to mathematical models and Herschel-Bulkley model showed the highest correlation coefficient. Lower moisture content (55%) produced higher yield stress and consistency index, but lower flow behavior index, whereas higher moisture content showed reverse effects. Job's-tears with $50{\sim}70%$ moisture contents showed a higher storage modulus (G') than loss modulus (G') at all frequencies, showing a higher concentrated polymer characteristics. However, higher moisture content (>75%) showed crossover point between G' and G', and frequency dependency. As the moisture content was increased, the amount of viscoelastic properties such as G', G', complex viscosity decreased during heating, and initial temperature and miximum value of viscoelastic properties shifted to higher temperatures, representing the moisture-dependence of Job's-tears upon theological properties.

  • Purpose: This survey was conducted to investigate the level of coronavirus disease 2019 (COVID-19)-related peritraumatic distress and job stress among clinical nurses and evaluate their effects on nursing performance. Methods: The participants were 115 nurses from 5 hospitals in 3 regions in Korea. The peritraumatic distress index (PDI), job stress, and nursing performance scales were used for the analysis. The data were analyzed using descriptive statistics, t-test, ANOVA, Pearson correlation coefficient, and multivariate regression analysis. Results: The level of peritraumatic distress of nurses was scored at 22.8 ± 9.26 (range 0 to 45). The level of job stress was scored at 2.69 ± 0.51 (range 1.3 to 3.7). The level of nursing performance was scored at 3.73 ± 0.51(range 1.76 to 5.0). Peritraumatic distress was observed to be positively correlated with job stress (r=.408, p<.001). However, peritraumatic distress and job stress were not correlated with nursing performance. In multivariate regression, the only variable seen to affect nursing performance was the work experience of the nurses. Work experience levels of five to fifteen years were observed to have a significant positive effect on nursing performance. Conclusion: The work experience of nurses directly influenced nursing performance during the pandemic period. Thus, to retain more nurses and to improve nursing performance, it would be necessary to develop various strategies to decrease their peritraumatic distress and job stress caused by the pandemic.

  • Purpose: This descriptive study aimed to identify shift nurses' retention intention, need satisfaction, calling and vocation, and job stress, as well as the effects of these factors on retention intention. Methods: The participants of this study were 193 nurses working shifts with more than three months' clinical experience at general hospitals. Data were collected using a structured questionnaire from February 1 to 28, 2023. Nurses' Retention Index and Nurse Needs Satisfaction Scale, Korean version of the Calling and Vocational Questionnaire, Korean Occupational Stress Scale were used. Data were analyzed using SPSS/WIN 23.0 program. Independent t-test, one-way ANOVA, Pearson's correlation analysis, and hierarchical multiple regression analysis were conducted for statistical analysis. Results: Regarding nurses' shift work, the mean scores for retention intention, needs satisfaction, calling and vocation, and job stress were 32.12±9.04, 94.87±14.74, 26.95±6.84, and 66.12±10.34. Moreover, the nurses' retention intention differed significantly by age, education level, religion, marital status, clinical experience, satisfaction with wage, and job satisfaction. Furthermore, retention intention was positively correlated with needs satisfaction and calling and vocation and negatively correlated with job stress. Needs satisfaction, and calling and vocation as well as education level of bachelor's degree, job satisfaction had positive effects on shift work nurses' retention intention. Job dissatisfaction had relatively negative effects on retention intention compared to having neutral job satisfaction. Conclusion: It is necessary to develop programs that promote needs satisfaction, calling and vocation, and job satisfaction to improve nurses' retention intention in relation to shift work; moreover, institutional support for acquiring a bachelor's degree or higher is needed.

  • Objectives: This study was conducted to investigate the association between job stress and mental health among male and female workers in a large electric manufacture company. Methods: A cross-sectional study was carried out on 3,228 employees who participated in annual medical check-up working in a large electric manufacture company in Gyeonggi Province. Medical check-up and self-administrated questionnaire were performed at the same time. Korean Occupational Stress Scale Short Form (KOSS-SF) and Psychosocial Wellbeing Index Short Form (PWI-SF) were applied to assess occupational stress and mental health. Hierarchical multiple linear regression and multiple logistic regression were performed to estimate the association between job stress and mental health. Results: The proportion of high risk of mental health was 17.1% in male, and 46.9% in women. Job stress had a greater effect on mental health than other general and work characteristics. All subscales of job stress were revealed to affect mental health. Bad occupational climate and lack of reward are the strongest risk factors in mental health of male and female respectively. Conclusions: Our results suggest that job stress could affect mental health among large electronic manufacture workers.

  • Purpose: The purpose of this study was to identify associations among the sleep disturbance, fatigue, job stress, and blood and body fluid (BBF) exposure of shift-work nurses. Methods: A total of 299 shift-work nurses from two tertiary hospitals were enrolled in this study. We used the Insomnia Severity Index (ISI), and the Fatigue Severity Scale (FSS), and the Korean Occupational Stress Scale-Short Form (KOSS-SF) to evaluate sleep disturbance, fatigue, and job stress, respectively. The data were analyzed using t-test or chi-squared test and Logistic regression analysis using the SPSS 23.0 program. Results: We found that 43.8% of participants reported BBF exposure over the past year. Splash or exposure to broken skin of BBF were most frequent (56.9%), and followed by needlestick injuries (30.4%) and sharp injuries (12.8%). Age, hospital, working period, level of stress, sleep disturbance ($ISI{\geq}15$), fatigue (FSS $score{\geq}4$), job demand and organizational climate subset in KOSS-SF were significantly associated with BBF exposure in shift-work nurses. In multivariate analysis after adjusting age and hospital, the risk factors of BBF exposure in shift-work nurses were the level of stress and fatigue (FSS $score{\geq}4$). Conclusion: Fatigue and job stress were related to BBF exposure in shift-work nurses. Our results suggest that management of sleep disturbance, fatigue, and high job stress in shift-work nurses is needed to reduce risk of BBF exposure.

  • The success of construction projects is heavily dependent on the work ability of the field managers who manage the execution of projects. The work ability of field managers is influenced by various elements such as job stress and individual characteristics. The purpose of this study is to reveal the factors influencing the work ability of construction field managers in Korea. Work ability is evaluated bases on the Work Ability Index(WAI) developed by the Finnish Institute of Occupational Health, while job stress is measured using the Korean Occupational Stress Questionnaire Short Form developed by the Korean Occupational Safety & Health Agency. The results showed that field managers under higher job stress have lower work abilities. In addition, it is revealed that exercise or religious practice have a positive influence on work ability. This study will help to increase the work ability and enable the efficient management of organization at building construction sites.
