Abstract: BACKGROUND: Currently, there are no assessment tools for measuring coping strategies for stress at work in the Korean language. OBJECTIVE: The purpose of this study was to translate the Latack Coping Scale to workplace stress into Korean and examine its psychometric properties in a Korean working population. METHODS: Translation of the the Latack Coping Scale was performed according to the scientific guidelines for cross-cultural adaptation. Two hundred and forty one general workers in Korea completed the new Korean version of the Latack Coping Scale as well as the Type D Personality Scale-14 (negative affectivity). Psychometric properties …(reliability and validity) were evaluated. RESULTS: Factor analysis yielded a model that was consistent with the originally proposed subscales of the questionnaire. Good to excellent internal consistency and measurement consistency over a one week interval were obtained for five subscales (Cronbach’s alpha; 0.61 to 0.86 and ICC (2.2); 0.80 to 0.87). Escape coping scales were positively associated with Type D personality while control coping scales were negatively associated with Type D personality. CONCLUSIONS: This Korean version of the Latack Coping Scale has shown excellent validity and reliability in the Korean working population. Organizations investigating work stress and coping methods in Korean workers can use this instrument with confidence. Show more

Abstract: BACKGROUND: Preschool teachers can easily become exhausted and worn out, otherwise known as job burnout. Studies have explored the effects of emotional labor strategies and psychological capital on job burnout; however, few have examined their trilateral relationship, especially the role of psychological capital with respect to emotional labor strategies and job burnout. OBJECTIVE: This study explored the mediating and moderating effects of psychological capital in the relationship between three kinds of emotional labor strategies and job burnout in preschool teachers. METHODS: A cross-sectional study was conducted among preschool teachers in China. A total of 355 preschool …teachers completed a self-report questionnaire, including three scales that measured emotional labor strategies, psychological capital, and job burnout. Resultant data were analyzed based on correlations, multiple regressions, and structural equation modeling. RESULTS: Results showed that for preschool teachers, two emotional labor strategies (deep acting and expression of natural emotion) were found to be negatively correlated with psychological capital and positively correlated with job burnout. However, surface acting was positively correlated with psychological capital and negatively correlated with job burnout. Psychological capital partially mediated the effects of the three emotional labor strategies on job burnout. Additionally, psychological capital significantly moderated the effects of surface acting and deep acting on job burnout. CONCLUSIONS: Psychological capital can significantly mediate and moderate the effects of emotional labor strategies on job burnout. Show more

Abstract: BACKGROUND: Standing desks are a low cost option for the reduction of sedentary behavior. OBJECTIVE: This study evaluated changes in utility and health outcomes during a standing desk intervention. METHODS: Thirty-five participants (BMI >25) who reported sitting an average of≥six hours per workday were recruited. Participants were randomized into a control or intervention group. Eleven were enrolled in the control group and 24 in the intervention group. Participants in the intervention group were outfitted with an adjustable standing desktop accessory while participants in the control group maintained a standard work desk. Self-reported and objective measures of …sedentary time during an eight hour workday were captured for a baseline and intervention period. Changes in health outcomes and workplace satisfaction were assessed after six months. RESULTS: Self-recorded sedentary behavior decreased by 25% after six months though no changes in health outcomes were observed. Subjective assessments of standing time were over-estimated by 10% (compared to accelerometer recordings) in the intervention group. The intervention group reported higher levels of satisfaction with comfort, customizability, and overall personal workplace. CONCLUSIONS: Despite a decrease in sedentary behavior, no changes in health outcomes occurred after a six month intervention. Future studies should incorporate objective measures of diet and physical activity to assess compensatory behaviors that may offset sedentary reduction. More sensitive health outcome measures should also be considered. Show more

Abstract: BACKGROUND: Metal co-exposure of human subjects is an important matter of public health concern. It has been shown that Acetylcholinesterase activity is a suitable biomarker for the neurological risk assessment of some metals. A few studies have reported neurotoxicity risk among humans in co-exposure to chromium and nickel. OBJECTIVE: In this study, AChE activity was assessed in occupational exposure to chromium (VI) and co-exposure to nickel (II) and chromium (VI). METHODS: Air sampling was done in chromium electroplating workshops with the NIOSH 7600 and OSHA ID-121 methods for chromium and nickel assessment. Thirty-two workers from hard …chromium plating and 30 from decorative chromium plating were evaluated, while AChE activity was measured by the Elman method. RESULTS: Personal exposure to chromium in 20% of the studied people exceeded the TWA set by ACGIH. Occupational exposure to nickel in 47% of the DCP subjects was found to be higher than TWA. Cholinergic inhibition in plating workers was marked by a decrease in AChE compared to controls. Subjects with chromium (VI) exposure contained significantly higher inhibition of AChE activity (p  < 0.001) than workers with co-exposure to nickel (II) and chromium (VI). CONCLUSIONS: The chromium-matched electroplaters have no significant difference in AChE activity. It can be concluded that cholinergic inhibition with chromium (VI) is higher than nickel (II) exposure. Show more

Abstract: BACKGROUND: Laptop computers are used in various places and situations. The number of laptop users experiencing musculoskeletal disorders (MSDs) has increased drastically due to, in part, inappropriate workstations. OBJECTIVE: To investigate the neck and shoulder postures, and muscle activity relative to perceived pain when using the laptop at a low-height table, sofa, and bed. METHODS: Twenty male participants aged 18–25 years were randomly assigned to perform laptop computer operation at 3 workstations for 10 minutes during which neck and shoulder angles, muscle activity, and pain were recorded by using an Electrogoniometer, Electromyography (EMG), and visual analog …scale (VAS), respectively. RESULTS: Neck flexions when working at the sofa (18.6°±12.2°) and bed (17.2°±10.5°) were significantly (p  < 0.05) greater than that at the low-height table (7.8°±6.5°). However, shoulder flexion when working at the low-height table (28.2°±13.0°) was significantly (p  < 0.05) greater than that at the sofa (13.8°±8.6°) and bed (10.91°±7.8°). Working at the low-height table caused the shoulder flexor muscle activity to be significantly (p  < 0.05) higher than working at the sofa and bed. Neck pain was reported during laptop computer use at the sofa and bed, and upper back pain when working at the low-height table. CONCLUSIONS: High neck flexion and pain were found while working at sofa and bed, whereas high muscle activity at shoulder and upper back pain were found while working at the low-height table.

Abstract: BACKGROUND: Musculoskeletal disorders are not properly managed in office workers because of their busy work life. In-house physical therapy is a good way to manage the musculoskeletal disorders in office workers. Despite the numerous advantages of in-house physical therapy, the establishment and research of in-house physical therapy were insufficient. OBJECTIVE: The purpose this study was to determine the characteristics of musculoskeletal disorders in office workers and to investigate their satisfaction with in-house physical therapy clinics and the associated factors. METHODS: In this study, 664 office workers who used in-house physical therapy clinics were surveyed for characteristics …of musculoskeletal disorders and satisfaction with in-house physical therapy clinics. RESULTS: Of these office workers, the most common causes of damage were nontraumatic (36.8%) and the most common lesion sites were the neck (30.3%) and lower back (25.6%). In the empirical characteristics of in-house physical therapy clinics, basic thermoelectric treatments were the most common (46.8%). The satisfaction with in-house physical therapy clinic was generally high. In addition, the cause of damage and treatment contents affected treatment-related and functional return-related satisfaction. CONCLUSION: In-house physical therapy, including therapeutic exercises and self-management education, is a good system to manage musculoskeletal disorders in office workers. Show more

Abstract: BACKGROUND: The quality of the places where workers take their breaks may affect the completeness of recovery in the time available. Little is known about how characteristics of a company canteen buffer the relationship between job demands and fatigue. OBJECTIVE: We addressed the possibility that the company canteen buffers the relationship between job demands and fatigue to the extent that workers perceive it to hold restorative quality. Further, we considered how the restorative quality of the canteen signals the provision of organizational support, another job resource thought to buffer the demands-fatigue relationship. ETHODS: A questionnaire was …completed by 141 male blue collars workers during their lunch break in the factory canteen of an Italian industrial organization. RESULTS: Canteen restorative quality correlated positively with organizational support. In multivariate regression analyses, the demands-fatigue association was weaker among workers who saw greater restorative quality in the canteen. This buffering effect was accounted for by a buffering effect of organizational support. CONCLUSIONS: When settings for rest in the workplace have higher restorative quality, they may better function as job resources in two respects: serving the immediate needs of workers for recovery from job demands, and signaling the interest of the organization in their well-being.

Abstract: BACKGROUND: The manual brick field industry is one of the most important and oldest industries in India, where millions of male and female workers make their livelihood. OBJECTIVE: To estimate the different ergonomic risk factors associated with brick making, identify potential gender differences and the prevalence of Work-related musculoskeletal disorders (WMSDs), physiological and psychological stress among the brickfield workers. METHODS: Brickfield workers - 152 male and 148 female were randomly selected from the 12 brickfields. The Modified Nordic Questionnaire was applied to assess the discomfort reported among both groups of brickfield workers. Objective measurement of physiological …parameters and lung function values were also recorded. RESULTS: From this study, it was revealed that there is significantly higher discomfort reported in hands, lower back and knees among female brick molders than male brick molders. The physiological parameters did not show any significant change between male brickfield workers and female brickfield workers. The mean values of FVC, FEV1 and PEFR for females were lower than those for male brickfield workers. CONCLUSION: This study concludes that female brickfield workers reported more discomfort than male brickfield workers; perhaps in part due to their additional domestic work responsibilities.
