Factors Associated with Quality on Sleep of Subway Workers by Shift-Work: Min Gi Kim, Won Chul Lee, Young Min Lee, Jae Hong Ryoo, Hawn Cheol Kim, Seung Won Yoo, Kyung Han Nam; Korean Journal of Occupational and Environmental Medicine 2008;20(4):326-334. Published online December 31, 2008; DOI: https://doi.org/10.35371/kjoem.2008.20.4.326

BACKGROUND
The sleep quality of subway drivers who work in the dark underground with an rotating shift system is generally poor, which can degrade the quality of a worker's life. This study examined the relationship between the sleep quality of subway worker and shift work by comparing three shift systems (rotating shift system, a three day shift system, and no-shift system).
METHOD
Questionnaires including The short form of the Korean Occupational Stress Scale (KOSS), Pittsburgh Sleep Questionnaire (PSQI), the worker's age, gender, job type, accident, near miss and shift system were given to a total of 1010 workers. The results of 759 qualified questionnaires (75.15 %) were analyzed using the SPSS (ver 12.0) program.
RESULT
The highest level of job stress was found among those working a rotating shift system followed by three shift system and no-shift system. The mean sleep quality score in the rotating shift workers was 5.1 (SD+/-3.2), which was greater than the sleep symptom score (5). 34.8% of rotating shift workers suffered from sleep symptoms. The sleep quality score by shift-work was significantly different. High job demand, strong external locus control, the experience of a near miss or an accident in the workplace during previous year has an adverse affect on the sleep quality. The sleep quality improved in case of a change into a no-shift system or a strong internal locus control.
CONCLUSION
A rotating shift system is more harmful to the quality of sleep in subway workers than a 3 shift system or no-shift system. In addition, job stress, personality, near miss and the experience of an accident affect the sleep quality of subway workers.

Association Between Job-Stress and VDT Work, and Musculoskeletal Symptoms of Neck and Shoulder Among White-Collar Workers: Eui Cheol Lee, Hawn Cheol Kim, Dal Young Jung, Dong Hyun Kim, Jong Han Leem, Shin Goo Park; Korean Journal of Occupational and Environmental Medicine 2007;19(3):187-195. Published online September 30, 2007; DOI: https://doi.org/10.35371/kjoem.2007.19.3.187

Abstract PDF

Objective: The purpose of this study was to evaluate and compare the association of job stress and working with video display terminal (VDT) to musculoskeletal symptoms of the neck-shoulder which were most common in white-collar workers.
METHODS
From 122 workplaces, 1,790 white-collar workers with no trauma, and no history of musculoskeletal disease were selected for the study. The questionnaire survey included general characteristics, work related characteristics, Job Content Questionnaire (JCQ) and musculoskeletal symptoms. Multiple logistic regression, adjusted for age, smoking status, drinking habit, housekeeping, work time, job tenure, and work-load change, were used to evaluate the effects of job stress and VDT-work on the symptoms.
RESULTS
The prevalence of neck-shoulder symptoms was overall 24.3% overall. The prevalence odds ratio of job demand (high/low) to neck-shoulder symptoms, adjusted for general and work-related factors, was 1.56 (95% confidence interval 1.12~2.17), and that of job strain (high strain/low strain) was 1.72 (1.07~2.79). However, VDT-work was not associated with neck-shoulder symptoms in the multiple logistic regression model.
CONCLUSIONS
To prevent musculoskeletal disorders in white-collar workers, it is important to consider psychosocial factors such as job demand and job strain, as well as VDT-work.

Relationship of Burdened Work and Musculoskeletal Symptoms in Small-to-medium-sized Enterprises.: Sin Goo Park, Hong Jae Chae, Joo Youn Shin, Dal Young Jung, Yong Kyu Kim, Tae Jin Jung, Jong Han Leem, Hawn Cheol Kim, Yeui Cheol Lee; Korean Journal of Occupational and Environmental Medicine 2006;18(1):59-66. Published online March 31, 2006; DOI: https://doi.org/10.35371/kjoem.2006.18.1.59

Abstract PDF

OBJECTIVE: This study was performed to evaluate relationship of burdened work and musculoskeletal symptoms in small-to-medium sized enterprises.
METHOD
After a questionnaire survey was administered to 9,950 workers in 122 workplace, 7,626 workers(76.6%) were finally selected for the study analysis. Industrial hygienists visited 122 small-to-medium sized enterprises to investigate the presence of burdened works within the workplace. The selection of jobs with significant burden was based on the Ministry of Labor's recent notification in 11 types of job description associated with musculoskeletal disorders. The subjects of this study were then divided into three categories. 1) non-burdened white collar workers, 2) non-burdened blue collar workers, and 3) burdened workers (include some VDT workers). Multiple logistic regression was used to evaluate the relationship between burdened work and musculoskeletal symptoms.
RESULTS
The burdened workers reported significantly more musculoskeletal symptoms than non-burdened white collar workers and non-burdened blue collar workers(OR:1.57, 95% CI: 1.314-1.875). There was no significant difference in reports of musculoskeletal symptoms between non-burdened white and blue collar workers.
CONCLUSION
To prevent or diminish musculoskeletal disorders in small-to-medium sized enterprises, we need to better manage burdened works.
