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.

The purpose of this study is to identify the factors influencing the musculoskeletal discomfort and the physical region related symptoms. The outcome of the study uses KOSHA Code H-30-2003 which defines possible symptoms into different categories. Symptom I, ll showing the highest occurrence rate in shoulder and neck regions and most of Symptom III, IV come from back region. Analysis of the factors influencing the musculoskeletal discomfort vary in different parts of the body. In the neck region, the discomfort related to rest and the computer keyboard. Gender affects the magnitude of pain in the shoulder region. Wrist pain is related to the chairs being used and back discomfort is influenced by shoulder exercise and the degree of rest taken. Physical fatigue due to work affects all the regions mentioned above. Conclusively, office workers are prone to the musculoskeletal discomfort due to their work environment. To alleviate this problem, the workers need to be educated with proper long-term musculoskeletal related health programs and exercise program containing various stretching methods. In addition, the effort to improve the variables in this study would help to reduce the rate of musculoskeletal discomfort.

Background: Assembly lines work is frequently associated to work-related upper limb musculoskeletal disorders. The related disability and absenteeism make it important to implement efficient health surveillance systems. The main objective of this study was to identify self-reported variables that can determine work-related upper limb musculoskeletal symptoms-discomfort/pain-during a 6-month follow-up. Methods: This was a prospective study with a 6-month follow-up period, performed in an assembly line. Upper limb musculoskeletal discomfort/pain was assessed through the presence of self-reported symptoms. Uni- and multivariate logistic regression analyses were used to evaluate which self-reported variables were associated to upper limb symptoms after 6 months at the present and to upper limbs symptoms in the past month. Results: Of the 200 workers at baseline, 145 replied to the survey after 6 months. For both outcomes, "having upper limb symptoms during the previous 6 months" and "education" were possible predictors. Conclusion: Our results suggest that having previous upper limb symptoms was related to its maintenance after 6 months, sustaining it as a specific determinant. It can be a hypothesis that this population had mainly workers with chronic symptoms, although our results give only limited support to self-reported indicators as determinants for upper limb symptoms. Nevertheless, the development of an efficient health surveillance system for high demanding jobs should implicate self-reported indicators, but also clinical and work conditions assessment should be accounted on the future.

Purpose: The present study attempted to find subjective musculoskeletal symptoms of operating room nurses (OR nurses) and then to use them as basic data for prevention and management of musculoskeletal symptoms of OR nurses. Method: This study was an exploratory research, and data were collected from OR nurses working in 8 polyclinics in Korea from July 26 to August 19, 2004, using a self-report questionnaire. The questionnaire contains items concerned with subjective musculoskeletal symptoms include ones with the presence of symptoms and with the degree of discomfort, in the joints such as neck, shoulder, arm/elbow, hand/wrist/finger and waist. For data collection, the aim of the study was explained to the operating room managers to obtain their help, and these questionnaires were sent to hospitals, and were retrieved by post. 271(90.3%) questionnaires were returned among those sent to 300 nurses. 249 questionnaires excluding 22 insufficient ones such as no response were used for data analysis. Data were analyzed using SPSS WIN 12.0. Subjective musculoskeletal symptoms were analyzed in the number and percentage. Result: 187(75.1%) nurses said they 'had' subjective musculoskeletal symptoms and 62 (24.9%) said they had 'nothing'. 130(52.2%), 125 (50.2%), 113 (45.4%), 86(34.5%), and 42 (16.9%) nurses had subjective musculoskeletal symptoms in waist, shoulder, hand/wrist/finger, neck, and arm/elbow, respectively. 51(27.3%) and 136 (72.7%) nurses complained of the pain in one site, and in two or more sites, respectively. In particular, 51% and 47.4% nurses said that they were 'discomforted' due to the pain in waist and in shoulder, respectively. Conclusion: Subjective musculoskeletal symptoms which OR nurses complained of were significant. This may cause difficulty in nursing tasks in the operating room. So various arrangements have to be made for OR nurse with subjective musculoskeletal symptoms at an early stage.

Musculoskeletal disorders are a major cause of occupational disabilities. Approximately thirty percent state that the major reason for an inability to work is a musculoskeletal problem. A farm work is associated with increased stress and trauma to joints. Chronic overuse injuries are a result of stresses that exceed the body's adaptive or healing capabilities. They can occur in bone, tendons and muscle-tendon-bone junctions. The aim of the investigation was to the study the frequency of pain, ache, and discomfort in the musculoskeletal system among farmers, to find possible correlations between these symptoms and various working positions and different working actions. A questionnaire was answered by 138 farmers. Of those who answered the questionnaire 82% had pain and discomfort from back, shoulders, arms in orders, The result showed that musculoskeletal pain predominate in the farming seasons, and of those who had pain and discomfort 89% thought that farm works had a correlation with the pain and discomfort of musculoskeletal system. But only 17% of quationnaire were put to periodic medical examinations, and 50% of those who had pain and discomfort consulted a doctor. Education in effective pain treatment should therefore be intensifide to ascertain that farmers in rural areas have satisfactory knowledge of the musculoskeletal pain as a chronic overuse syndrome.

Purpose: This study was done to examine physical, psycho-social, and individual factors influencing musculoskeletal symptoms among Korean military trainees. Methods: Using a correlation study design, military trainees who had completed almost of all the basic combat training (BCT) days were recruited from two military training units selected by convenience sampling. Data from 415 participants were analyzed. Results: Prevalence of musculoskeletal symptoms was 29.6% defined as a participant having pain or discomfort in one or more body parts during training hours for more than seven consecutive days. Back/pelvic (10.8%), knees (10.1%), shoulders (7.7%), feet/toes (5.6%), ankles (4.8%) were prone to musculoskeletal symptoms. Musculoskeletal symptoms appeared to be related to physical exertion during BCT, stress during BCT, social support from fellow trainees, or previous musculoskeletal injuries. In the logistic regression model, physical exertion during BCT (OR=2.27, 95% CI: 1.42~3.65), stress during BCT (OR=1.79, 95% CI: 1.15~2.78), and previous musculoskeletal injuries (OR=1.58, 95% CI: 1.01~2.47) were the significant factors affecting prevalence of musculoskeletal symptoms. Conclusion: Findings indicate that physical exertion and psycho-social stress should be managed to prevent musculoskeletal symptoms in military trainees with more attention being given to trainees having a history of musculoskeletal injuries.

This study was to investigate the prevalence rate of musculoskeletal disorders in relation to general characteristic factors, living environment factors, and work environment factors for sonographer's. For the response questions, the guidelines for musculoskeletal burden work were used. For statistical analysis, SPSS 26.0 version was used. For the common body parts of the sonographer's who responded, the prevalence was investigated by dividing the group into a group with high pain or discomfort and a group with low pain or discomfort according to the degree to which they experienced symptoms during the past 12 months. Multiple logistic regression analysis was used to determine the variance inflation factor(VIF), odds ratio (OR) and corresponding 95% confidence interval (CI). A p-value of <0.05 was considered statistically significant. As a result, housework hours, examination history, regular physical activity, number of patient examinations per day, and sitting posture were investigated as variables for rate musculoskeletal disorders. The sonographer's occupational group was found to have a high prevalence rate of musculoskeletal disorders like various other occupational groups. Based on the results of this study, it is judged that musculoskeletal disorders can be reduced by recognizing musculoskeletal disorders and improving work environment factors.

PURPOSE: It is known that work stress was linked to WRMDs in workplace. The purpose of this study was to identify the characteristics of work related musculoskeletal disorders (WRMDs) related to job stress among prosthetists and orthotists. METHODS: Eighty-six self-reported symptoms of discomfort (SRSD) and job stress were collected by questionnaire and analyzed. RESULTS: The results were as follows: Over 70% of respondents had WRMDs. The shoulder was the most painful region and each of "within 15 minutes", "once a week" and "severe moving or doing exercise" items were main characteristics in the SRSD. Finally, the "repetition of simple work" item in job stress ranked as resulting in "often discomfort" in over 43% of respondents. Additionally, there was a statistically significant correlation between job stress and pain intensity (p<.05, $r_s$=.36). CONCLUSION: Further studies are needed to identify the factors affecting musculoskeletal symptoms and job stress of prosthetists and orthotists in Korea.

Background: This study was planned to investigate the relationship between musculoskeletal problems, depression, and quality of life in students preparing for university entrance exams. Methods: A total of 180 students were included in the study, 104 were female (57.77%), and 76 were male (42.22%). Students were reached through the cram schools ("dershane") in Denizli. Musculoskeletal system problems, depression status, and quality of life were determined with the Musculoskeletal-Postural Discomfort Scale (MDS), Boratav Depression Screen Scale (Bordepta), and Short Form-36 (SF-36), respectively. Demographic data, daily study, and sleep duration were also recorded. Results: Students have moderate musculoskeletal discomfort. Musculoskeletal disorders and depressive symptoms are more observed in female students than male students (P = 0.000). The SF-36 results were significantly negatively correlated with the MDS and Bordepta scores. A significant positive correlation was found between musculoskeletal disorders and depression status (r = 0.351, P = 0.000). Sleep duration was negatively correlated with the MDS and Bordepta (r = -0.209, P = 0.005; r = -0.148, P = 0.047, respectively) and positively correlated with the SF-36 role limitation/emotional and social functioning subscales (r = 0.225, P = 0.002 and r = 0.191, P = 0.010 respectively). Conclusions: Musculoskeletal problems and depression status negatively affects general health status especially in female students who are preparing for university entrance examinations. Students should be informed about musculoskeletal problems by healthcare professionals and the study room, tables, and chairs should be arranged ergonomically. Further studies might be determined that why musculoskeletal disorders and depression status are more widely among female students.
