This cross-sectional study was investigated musculoskeletal discomfort symptoms and related factors on some middle high school teachers. Self-questionnaire of KOSHA CODE H-30-2003 was done with 250 teachers from 1st to 15th October, 2010, the data from 231 teachers (68 male, 163 female) was statistically analyzed to search the factors related to musculoskeletal discomfort symptoms. According to NIOSH rate of musculoskeletal discomfort symptoms by body parts was 36.8%. Musculoskeletal discomfort symptoms related to age, school types, subjective health status, housekeeping time, VDT work time and regular rest. After adjusting for related variables, odds ratio (OR) of musculoskeletal discomfort symptoms was correlation significantly to subjective health status unhealthy (OR 11.75, 95% Confidence Interval, CI, 3.56-378.78). In addition, ORs (95% CI) of age (40-49) and housekeeping time (${\geq}3$) were 4.63 (1.82-26.18) and 4.33 (1.97-19.34). Analysis of the factors influencing the musculoskeletal discomfort symptoms vary in different parts of the body. The most discomfort symptoms by parts was neck (26.0%) and shoulder (30.0%). In the neck region was related to subjective health status and regular rest. In the shoulder and waist region was subjective health status and sex. Age was wrist/finger, leg/foot was related to subjective health status, sex and VDT work time. Age, school types, subjective health status, housekeeping time, VDT work time and regular rest related to musculoskeletal discomfort symptoms and the most discomfort symptoms by parts was neck and shoulder.

Purpose: This study aimed to investigate the prevalence of musculoskeletal symptoms (MSSs) and their correlation with subjective health condition (SHC) among emergency medical technicians (EMTs). Methods: A self-reported questionnaire was disseminated to EMTs (N=257) at emergency medical institutions and fire stations. Results: The prevalence of MSSs was very high in the studied EMTs: 88.3% reported having MSSs. The most commonly affected site was the lower back (73.9%) followed by the neck (56.8%) and the shoulder (55.6%). MSSs were more common in women than in men, and its frequency increased with age. MSSs in the neck and shoulder were more increased in EMTs with < 1 year of service. MSSs in the hand / wrist / finger or leg / foot were significantly increased in EMTs of emergency medical institutions than those of fire stations. Job satisfaction was significantly lower in those with MSSs of the lower back. The subjective heath condition was decreased with age, marriage, or smoking. There was significant corelation between MSSs and SHC. Conclusion: This study suggests that MSSs are a reasonably common problem for EMTs, and that solutions need to be imposed such as some actual tasks or items related to work postures, work control, and work organization.

The purpose of this study was to investigate the related factor for the prevalence of musculoskeletal symptoms among 212 sewing worker. The survey was performed with self-administered questionnaire for the risk factors related to musculoskeletal disorders(MSDs) from August 5 to 7 in 2005. The prevalence of musculoskeletal symptoms were 75.8% and the those of the local symptoms were 71.7 % for shoulder, 60.4 % for neck, 35.8 % for arm and 50.9 % for wrist. The risk factors related the self-reported MSDs had not shown in general characteristics. But, there was a significant difference between daily working hour and wrist, working speed and neck, the degree of satisfaction and wrist for work related factor. Also, it was shown the significant difference between chair height and neck, the height of sewing machine and wrist among the space below work station, neck, waist for the prevalence of musculoskeletal symptoms. The significant correlation was shown for daily working hour and wrist, working speed and arm, work load and shoulder and the degree of satisfaction and arm for work related subjective symptom. Considering above results, it is suggested the ergonomic design be provided to working hour, the height of chair and work station as well as daily working hour even there is a significant difference for the prevalence of symptoms in each body part for sewing workers.

This study was conducted to evaluate the differences in symptoms of work-related musculoskeletal disorders (WMSDs) and health-related quality of life (HRQoL) between vinylhouse farmers and non-vinylhouse farmers. The study included 118 residents who lived in a rural community. All subjects were assigned to the vinylhouse farmers group (N=58) and the non-vinylhouse farmers group (N=60) according to main agricultural work type. All respondents were interviewed by means of a structured questionnaire. WMSDs symptoms were measured by a self- assessed questionnaire on symptoms of musculoskeletal disorders, and HRQoL was measured by SF-36. Vinylhouse farmers had significant more symptoms of WMSDs in each regional parts of musculoskeletal system, and had significant poor total health status in SF-36. Symptoms of WMSDs were most reliable risk factor for HRQoL. Various health promotion interventions are needed to prevent WMSDs in all farmers and especially vinylhouse workers.

Although dental laboratory technicians are prone to be exposed to various work-related health hazardous materials such as dusts, chemicals, etc., the prevalence and nature of work-related health problems of them have not been a matter of great concern in the field of occupational health service in Korea. The purpose of the present investigation was to describe a collected profile of subjective health symptoms and their attributable factors in Korean dental laboratory technicians. A questionnaire listing five groups of health symptoms and five health symptom-related factors was mailed to randomly selected 1,900 dental laboratory technicians. Among them, 1,344 dental laboratory technicians filled out the questionnaires and returnde them. Five groups of health symptoms included musculoskeletal symptom, dermal symptoms, respiratory symptoms, eys symptoms, and ear symptoms. Five health symptom-related factors were occupational environment-related health risk factors, work history, health related habits and status, use of personal protective equipment and general characteristics. Detailed parameters of health risk factors were work posture, vibration, and chemical or physical hazards such as dust, fume, vapor, solvent, light, and noise for occupational environment-related factors; work place, area, number of employees, work hours, career, work part, and work load for work history; Broca's index, hours of sleep, eating, smoking, alcohol, exercise, health examination, and self assessed health status for health habits and status; face masks, goggles, and so on for use of personal protective equipment, and; age, sex, marital status, and education for general characteristics. Before the start of main survey, a pilot survey was carried out for validity and reliability tests of the questionnaire. All the data obtained were coded and analyzed with PC/SAS 6.12 program. The prevalence of health symptoms was the highest in musculoskelton (87.3%), and followde by eyes (78.9%), respiratory organs (64.3%), ears (57.8%), and skin (52.2%) in descending order. Statistically significant risk factors by multiple logistic regression analyses were sex, health examination, self assessed health status, and hand/finger posture in musculoskeletal symptoms; sex, self assessed health status, career, acid gas, and hand contact with resin mixture in deraml symptoms; Broka's smoking, exercise, self assessed health status, and face mask in respiratory symptoms; sex, hours of sleep, self assessed health status, work hours, work load, plaster dust, inadequate lighting, and goggle in eys symptoms, and eating, smoking, self assessed health status, and work load in ear symptoms. With the above considerations in mind, prevalence of subjective symptoms among Korean dental laboratory technicians was relatively high, and they were attributable to most of the occupational environment-related factors, work history, use of personal protective equipment, health habits and status, and general characteristics. Particularly, it is suggested that health promotion programs for promoting self- assessed health status and smoking cessation, preventive measures for protection of the female technicians’health, and reducing work load be necessary, since those factors were associated with more than one subjective symptom.

Purpose: The purpose of this study was to compare subjective symptoms of VDT between computer-addicted and non-addicted adolescents. Method: A descriptive survey design was used and 646 students in one middle and two high schools were selected as participants. Result: The VDT subjective symptoms and degree of severity differed according to whether the students were computer-addicted or not, and in all symptoms, general, musculoskeletal, eye and mental, the mean score for subjective symptoms was higher in the addicted group than in the non-addicted group. The score for VDT subjective symptoms was highest in the addicted group for girls and students who were not healthy. The most frequent physical symptom reported by students who visited the school health room for a health problem after using the computer was headache. The most frequent type of treatment at the school health room was treatment of the symptom. Conclusions: This study suggests that students must acquire correct habits in computer use and be careful not to be addicted to the computer in order to avoid VDT syndrome. For this, educational authorities should develop computer-related health education programs and start the programs from the lower grades of elementary school.
