This study investigated the muscular dystrophin levels in freely moving Australian cattle mainly fed grass, freely moving Korean cattle fed mainly a grain diet, and Korean cattle fed a grain diet but housed in a relatively limited space of a cow house. The total skeletal muscle specimens of 244 cattle were collected and immediately fixed in 10% neutral formalin. The same area was biopsied from the cattle in both countries. The findings showed that fatty infiltration is highly correlated with membrane-associated protein degradation in skeletal muscle, and that among several membrane-associated proteins, dystrophin showed the most significant reduction in expression in the cattle with fatty infiltration. Similarly, CD36 was more highly expressed in the cattle with fatty infiltration of skeletal muscle. Various breeding factors, such as oxidative stress; the presence of oxidized lipids in the diet; and environmental factors such as exercise, temperature and amount of time spent, may have critical effects on the degradation of normal cytoskeleton proteins, which are required for maintaining normal skeletal muscle architecture. Among the sarcolemma membrane-associated proteins, dystrophin is the most sensitive membrane protein that is involved muscular dystrophy and muscular degeneration. Thus, the present findings may be useful for studies on muscular dystrophy in humans or the pathogenesis of muscular diseases in animal models.

Purpose : The purpose of this study was to identify musculoskeletal symptom and pain related working posture with operation-room workers. Methods: The subjects of this study were 73 people who were working from hospital operating-room. A questionnaire consisting of general characteristics, pain symptoms, and pain frequency was given. Objective working posture analysis was done by using REBA after recording moving images in hospital operating-rooms. Results: The result were as follows. The risk level of musculoskeletal symptom related working posture was high, and the management level was at the least 2; 'some management was required for musculoskeletal symptom'. The frequency of pain was 3~4 times/week and the severe pain were experienced from legs, neck, and shoulder. The result of relation of general characteristics and pain were significant variable with sex, age, marital status, weight, past working history, average working time(hr/day), working style, and working department. Conclusion: These results contribute to a better understanding of operation-room workers have high possibility of musculoskeletal disease and are severe musculoskeltal pain related working posture.

The purpose of this study was to analyze the factors of health services that satisfy chronic musculoskeletal patients in the northern part of Gyeong-buk, South Korea. One hundred and seven chronic musculoskeletal patients who had visited a clinic in Gyeong-buk were recruited for this study. The data were collected through a questionnaire survey administered from May 7 to June 6, 2012. The collected data were analyzed by multiple regression analysis. The major findings of this research are as follows. The chronic musculoskeletal patients' satisfaction was determined by the "physical therapist's explanation," "registration process," "home exercise," "respect from staff," and whether the physical therapist and staff "listened to concerns." The chronic musculoskeletal patients' likely to revisit is strongly related to "physical therapist's explanation," "registration process," and "up-to-date equipment." Therefore, it is very important for clinics to improve the quality of the "physical therapist's explanation," "registration process," "respect from staff," "informed consent," "up-to-date equipment," and "home exercise." Furthermore, it is expected that the outcomes of this study will contribute to the customer satisfaction of chronic musculoskeletal patients in clinics.

This study aims to identify the relations between self-reported symptoms of industrial workers work-related musculoskeletal disorders and psychosocial factors. The subjects of the study were 120 male workers who were using the rehabilitation center of K company and they were voluntarily interviewed with a use of organized questionnaire. Except the responses from eighteen subjects whose responses were insincere and who had disorders in musculoskeletal areas, the responses of 102 ones were decided for the final analysis. The results showed that there were significant differences in self-reported symptoms of work-related musculoskeletal disorders between the subjects according to smoking, physical burden and self-efficacy. To prevent and control work-related musculoskeletal disorders, multi-characteristic aspects of how the disorders appeared and psychological factors, in particular, self-efficacy, should be carefully considered. Then, as psychosocial factors affect musculoskeletal disorders, relations between the disorders and factors should be analysed through long-term follow-up studies, psychosocial factors should be actively intervened, and the effect should be evaluated.

This study aims to identify the symptoms and related factors of musculoskeletal disorders among teacher librarians, with the goal of raising awareness about their health and safety, and providing foundational data for the prevention of musculoskeletal disorders. An online survey was conducted with teacher librarians working in elementary, middle, and high school libraries, and data were analyzed based on responses from 204 participants. The survey provided by KOSHA was utilized to identify the musculoskeletal disorder symptoms and the collected data were analyzed using the SPSS 29.0 program. Of the 204 librarian teachers, 92.6% have experienced symptoms of musculoskeletal disorders such as pain, soreness, and tingling in relation to their work over the past year. Additionally, 20.6% were classified as normal, 44.1% as requiring management, and 35.3% as reporting pain. By body part, the highest incidence was reported in the hands·wrists·fingers, followed by the lower back, shoulders, neck, arms·elbows, and legs·feet.

In this study we investigated the effects of physical therapeutic intervention through electromyography, ultrasonographic imaging and changes of the IL-$1{\beta}$, IGF-1 and IGF-2 in skeletal muscle of rats injured experimentally. The twenty Sprague-Dawley male rats were randomly divided into the 4 groups: a normal, a control, a low power laser and a neuromuscular electrical stimulation group. Abnormal spontaneous activities had not been shown, both in normal and skeletal muscle injured rats. The maximum diameter of the calf muscle was significantly increased in the low power laser and neuromuscular electrical stimulation groups compared with control group. The level of the serum IL-$1{\beta}$ was more decreased in the low power laser and neuromuscular electrical stimulation groups than that of control group. The activation level of the IGF-1 and the IGF-2 were significantly higher in the control, low power laser and neuromuscular electrical stimulation groups than that of normal group. However, there was no statistically significant difference among the control, low power laser and neuromuscular electrical stimulation groups.
