Risk Assessment and Intervention of Ergonomic Risk Factor in Beekeeping / 農村醫學 地域保健

OBJECTIVES: The purpose of this study was to assess the ergonomic risk factors in beekeeping, and to evaluate the effectiveness of assistive device hive lift. METHODS: This study included 30 subjects of beekeeper in Pocheon, Korea. We assessed the ergonomic risk of main task in beekeeping with NLE, OWAS and evaluate the effectiveness of hive lift. We also surveyed prevalence of musculoskeletal symptoms among the subjects based on the Korea Working Condition Survey. RESULTS: Moving to different floral origin, internal inspection of beehives, feeding syrup is the most burdensome to musculoskeletal system (NLE LI value=2~3. OWAS action category=4). The prevalence of musculoskeletal symptoms (lower and upper extremities) among the subjects was over 80 %. The introduction of assistive devices in the three hazardous tasks has dramatically reduced the risk by removing manual lifting hives (OWAS action category<1). CONCLUSIONS: Beekeeping is a heavy workload on the musculoskeletal system because it has a lot of manual lifting task. As a result of applying the hive lift, the burden could be reduced.

The Relationship of Physical and Psychosocial Risk Factors to Work-related Musculoskeletal Upper Extremity Symptoms amongst Male Automobile Manufacturing Workers / 대한산업의학회지

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.

Job Stress and Musculoskeletal Symptoms of Care Workers at Medical Welfare Facilities for Elders

PURPOSE: This study is a descriptive survey to find out musculoskeletal symptoms in care workers working at medical welfare facilities for elders and factors affecting such symptoms. METHODS: Data were collected from 115 care workers selected through convenient sampling from 6 medical welfare facilities in Seoul and Gyeonggi-do during the period from May 15th to May 19th, 2006. The Korean version of Job Content Questionnaire (JCQ) were used. RESULT: Of the subjects, 81.7% complained of musculoskeletal symptoms in two or more parts of their body. The frequency of body parts with musculoskeletal symptoms was high in order of shoulder, leg/foot, waist, neck/hand/wrist/finger and arm/elbow. The average job insecurity instability in the age group of 50-59 was 9.19, the average degree of regular exercise was 59.68, and the average job demand in those diagnosed with musculoskeletal diseases was 47.06, and the average job demand in those wounded during exercise or by an accident was 47.78, and all these were statistically significant. The heavier physical load in their work was, the higher their complaint of musculoskeletal symptoms was. In the lower social support group, the degree of complaint on musculoskeletal symptoms was remarkably high. CONCLUSION: The physical load of their duty and social support worked as the factors affecting musculoskeletal symptoms in care workers.

Relationship of Burdened Work and Musculoskeletal Symptoms in Small-to-medium-sized Enterprises / 대한산업의학회지

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.

The Relationship between Musculoskeletal Symptoms and Job Stress & Intensity of Labor among Shipbuilding Workers / 대한산업의학회지

OBJECTIVES: This study aimed to reveal the multiple factors that are related to the work-related musculoskeletal disorders (WMSDs) of shipbuilding workers, and to elucidate the relationship between musculoskeletal symptoms and factors such as the change of working conditions, job stress and physical workload. METHODS: The study sample comprised 1,059 shipbuilding workers. A structured-questionnaire was used to assess the general characteristics, job stress, psychosocial well-being index (PWI), physical workload, change of working conditions and information concerning musculoskeletal symptoms. We estimated the relations of job stress, physical workload and intensity of labour to musculoskeletal symptoms using univariate and multiple logistic regression analyses. RESULTS: The symptom prevalence of musculoskeletal disorders in any part of the body was 89.5% by 'criteria 1'in the order of back (58.6%) and shoulder (56.3%). After adjustment for sociodemographic factors, posture factor (Odds ratio [OR]=1.06, 95% confidence interval [ C I ] = 1 . 0 0~1.12), non-posture factor (OR=1.17, CI=1.05~1.31), Borg scale (OR=1.15, C I = 1 . 0 0~1.32), relative work intensity increase (OR=1.92, CI=1.08~3.41), labor flexibility increase (OR=2.04, CI=1.04~4.01), high job demand (OR=2.68, CI=1.48~4.88), and high risk stress group (OR=13.50, CI=3.15~57.97) were all found to be significantly associated with musculoskeletal disorders. CONCLUSION: These results suggest that WMSDs have multiple risk factors such as stress, physical workload and change of working conditions. High job demand, increased relative intensification of work and increased flexibility, especially such as subcontract, outsourcing and importing of contingent work, were very important factors associated with increasing WMSDs.

Symptom Prevalence and Related Factors of Upper Limb Musculoskeletal Symptoms in Automobile Related Job Workers / 대한산업의학회지

OBJECTIVES: The purpose of this study was to determine the prevalence and related factors of upper limb musculoskeltal symptoms among workers in automobile related jobs. METHODS: Two-hundred and twenty-one workers were volunteered in this 'study consisting of 112 seat installers and 109 auto mechanics. A questionnaire was administered to the workers consisting of questions on demographics, work type and duration, sleep hours, health habits, and standardized descriptions of NJOSH on musculoskeletal symptoms. RESULTS: Complaint rates of neck and upper extremity musculoskeletal symptoms by anatomical site were as follows: shoulder, 52.0%; neck, 47.1%; wrist and hand, 39.4 elbow, 26.2% and; arm, 24.4%. Significantly higher prevalence of shoulder musculoskele tal symptom was found in middle school than high school graduate, married than unmar ned, less than 6 hours sleep than over 6 hours sleep and, seat installer than auto mechanic group. A significantly higher prevalence of arm, elbow, hand and wrist mus loskeletal symptoms was disclosed in the less than 6 hours sleep than over 6 hours sleep group and the seat installer than the auto mechanic group. Multiple logistic regression analysis identified education, sleep hours and, job type as the main affecting factors for shoulder musculoskeletal symptoms. Sleep hours and job type were the main affecting factors for wrist and hand musculoskeletal symptoms. Sleep hours were the main affecting factors for arm and elbow musculoskeletal symptoms. CONCLUSIONS: The prevalence of neck and upper limb musculoskeletal symptoms was high in workers who did routine tasks at confined places like seat install-line work. It is recommended that workers performing simple and routine tasks be provided adequate sleep time since lack of sleep was the main affecting factor for most upper limb mus loskeletal symptoms in automobile factory related jobs workers.
