RESUMEN
OBJECTIVES: This study was conducted to investigate the association between emotional labor and dysmenorrhea among women working in sales and call centers in Seoul, South Korea. METHODS: Working women in sales jobs and call centers in Seoul were interviewed face-to-face by well-trained interviewers. In total, 975 participants were analyzed in the final model. Emotional labor was measured using a constructed questionnaire with two components: an emotive effort component with three questions and an emotive dissonance component with five questions. To examine the association between emotional labor and dysmenorrhea, chi-squared tests and logistic regression were applied. RESULTS: The prevalence of dysmenorrhea among sales workers and call center workers were 43.0% and 61.1%, respectively. The adjusted odds ratios (OR) of emotive effort and emotive dissonance for dysmenorrhea in call center workers were 1.88 (95% confidence interval [CI], 1.07-3.28) and 1.72 (95% CI, 1.13-2.63), respectively. The adjusted OR of emotive effort and emotive dissonance for dysmenorrhea in sales workers were 1.71 (95% CI, 0.92-3.16) and 1.15 (95% CI, 0.67-1.98), respectively. CONCLUSIONS: Emotional labor was found to be associated with dysmenorrhea in call center workers. Further studies to investigate other factors, such as management strategies and the relationship between emotional labor and dysmenorrhea, are needed to support interventions to prevent dysmenorrhea that will further promote the quality of health and life of working women.

OBJECTIVES: The objective of this study was to determine the relationship of physical and psychosocial risk factors to work-related musculoskeletal upper extremity symptoms amongst automobile manufacturing workers. METHODS: The cross-sectional study was conducted using male automobile manufacturing workers in order to examine the relationship of physical and psychosocial risk factors to work-related musculoskeletal upper extremity symptoms. A total of 1,793 male workers were asked to complete a self-administered questionnaire. The questionnaire consisted of questions regarding general characteristics, health related behaviors, work-related characteristics, job stress, ergonomic risk factors, and the presence of musculoskeletal symptoms (neck, shoulder, arm, and hand). Work-related musculoskeletal symptoms were evaluated using the National Institute of Occupational Safety and Health (NIOSH) surveillance criteria. In order to measure the physical risk factors, the American National Standard Institute (ANSI) Z-365 Quick checklist was incorporated into the questionnaire. Job stressors were measured using the Korean Occupational Stress Scale (KOSS). A binary logistic regression analysis was performed that examined the relationship of physical and psychosocial risk factors to musculoskeletal symptoms. RESULTS: The result showed that the physical and psychosocial risk factors were associated with musculoskeletal upper extremity symptoms. The workers with high physical risk factors reported more musculoskeletal symptoms than those having low physical risk factors (OR: 2.37, 95% CI: 1.56~3.62). The workers with high job stress were more likely to have an increased risk of musculoskeletal upper extremity symptom compared to those with normal job stress (OR: 2.65, 95% CI: 2.03~3.47). A significant relationship between the combined effects of physical and psychosocial risk factors on musculoskeletal upper extremity symptoms was also found. The workers exposed to high physical risk factors, high job stress, and long working hours were more likely to report musculoskeletal symptoms than those having low physical risk factors, normal job stress and moderate working hours(OR: 2.37, 95% CI: 1.56~3.62). CONCLUSIONS: The results suggest that some physical and psychosocial risk factors increase the risk of work-related musculoskeletal upper extremity symptoms amongst automobile manufacturing workers. In order to prevent or reduce musculoskeletal disorders amongst automobile manufacturing workers, it is strongly recommended to manage the physical psychosocial risks occurring in the workplace.

OBJECTIVES: A growing body of research has documented that job stress has a pivotal role in developing adverse health outcomes. However, little is known about the relationship between farmers' job stress and health outcomes. This study was undertaken to identify the relationship between job stress and self-perceived fatigue in Korean farmers. METHODS: A total of 526 Korean farmers were asked to participate in this study. A self-administered questionnaire was used to assess the participants' general characteristics, job stress and self-perceived fatigue. Job stress was measured using a forty-eight item Farm Stressor Inventory (FSI), and the self-perceived fatigue was estimated by Multidimensional Fatigue Scale (MFS). Binary logistic regression analysis was conducted to examine the relationship between job stress and self-perceived fatigue. RESULTS: The result showed that job stress was associated with self-perceived fatigue. For the farmers with high job stress, the risk of self-perceived fatigue was more likely to increase compared to those with low job stress. For males, labor intensity (OR, 3.88; 95% CI, 1.91~7.89), job environment (OR, 2.45; 95% CI, 1.22~4.93), social support (OR, 2.10; 95% CI, 1.07~4.13), social isolation (OR, 2.45; 95% CI, 1.15~5.60), financial problems (OR, 3.25; 95% CI, 1.53~6.91), uncertainty (OR, 2.48; 95% CI, 1.30~4.75) and health problems (OR, 5.77; 95% CI, 2.46~13.53) were associated with self-perceived fatigue. For females, job environment (OR, 2.23; 95% CI, 1.22~4.08), social isolation (OR, 2.08; 95% CI, 1.05-4.15), physical environment & weather condition (OR, 2.61; 95% CI, 1.33~5.12), financial problems (OR, 2.87; 95% CI, 1.55~5.32), uncertainty (OR, 3.65; 95% CI, 1.95~6.83) and health problems (OR, 3.38; 95% CI, 1.57~7.27) were associated with self-perceived fatigue. CONCLUSIONS: This result suggests that farmers' job stress plays a role in the development of fatigue, and job stressors related to fatigue are slightly different according to gender.

BACKGROUND AND OBJECTIVES: Otitis media with effusion (OME) is one of the most common diseases in children and may be frequently related with dizziness. However, the association between OME and dizziness seems to be not clear and remains controversy. The purpose of this study was to determine the incidence of dizziness in children with long lasting OME, and to investigate the difference in vestibular functions between children with long lasting OME and the control group. MATERIALS AND METHOD: Thirty one children who had long-lasting OME over than 6 months (study group) and 28 normal hearing children without OME who were scheduled for adenotonsillectomy (control group), were given questionnaires and vestibular function tests (VFT) including electronystagmography (ENG) and rotation chair test (RCT). Statistical analysis was performed with chi-square test. RESULTS: Dizziness was found in 7 (22.6%) of 31 children in the study group and 2 (7.1%) of 28 children in the control group (p>0.05). The difference of abnormal findings in VFT between the study group and the control was not significant except visual vestibulo-ocular reflex (VVOR) in RCT. Most of the correlations in the study group, bilateral vs. unilateral OME, OME with dizziness vs. OME without dizziness, and preoperative vs. postoperative, were not significant. CONCLUSION: We did not find any evidences of significant difference of the incidence of dizziness and findings of VFT between children with long lasting OME and children without OME. However, there was a significant abnormal response in VVOR in RCT in children with long-lasting OME, suggesting the children with OME may be more dependent on the nonvestibular system including visual compensation to maintain balance.
