This study is made for the survey of the effectiveness of the auricular reflexology, now accepted as a part of alternative medicine, applied to the patients of musculoskeltal disease patients, and data about its cognition and the success rate of the therapy. 106 patient was employed in this study who works in various part in a company in Jun-ju in Junrabukdo. From them, data such as, musculoskeletal symptoms by questionnaire examination, and data from ear inspections and interviews were collected and used for the basal data. Auricular reflexology therapies were applied to them at the areas that reflect the musculoskeletal system, for five times, each time with intervals of three or four days. The data about the effectiveness were collected by questionnaire examination, including descriptive answers. The results are as follows; cognition to the auricular reflexology was 62.3%, and acceptance rate of this method was 81.1%. From this results, I think that this therapy can be easily acceptable. The success rates of this therapy were 32.1% after 1 time application, and 84.9% after 5 times applications. This result shows that auricular reflexology therapy has therapeutic effect in musculoskeletal diseases, and the success rates increase according to the application times. Between sex, its success rate were 80% in male patients, and 88.5% in female patients, so this therapy is rather more effective in female patients. According to the body weight, the success rate were 85.8% in normal weight patients, and 71.5% in over- weight patients, so this therapy is more effective in normal weight patients. Comparisons according to other factors, such as age, marriage state etc. shows no definite differences. Conclusively, I think that auricular reflex therapy is easy and useful preventative and treatment method in our usual life. With more investigation, we can apply this method to other musculoskeletal diseases and to the diseases of other systems in the body, I hope so.

In 2003, Korean government made the 11 scopes of overburdened work[Ministry of Labor(MOL), Notification No. 2003-24] to prevent musculoskeletal disorders(MSDs). MOL Notification was established based on 'Washington Administrative Code 296-62-051, Ergonomics'. When initially investigating the contents, the labor unions and the specialists pointed out the possibility of devaluation on risk factors of MSDs. The present study aimed to compare the result of the NIOSH revised lifting equation(NLE) analysis with the MOL Notification(No.8, 9, 10) on manual lifting tasks. A study sample of 568 manual lifting tasks (automobile parts, foods, and tire manufacture) were evaluated for this study. All 502 tasks exceed lifting index(LI) of 1.0, but 276 tasks(55.0%) out of 502 tasks were evaluated non-over burdened work for musculoskeletal system by the MOL Notification. Particularly, 47 tasks(30.9%), in spite of exceeding LI of 3.0, were evaluated non-over burdened work. This study has shown the possibility of devaluation on risk factors of MSDs, when evaluated by MOL Notification. Therefore, it will be necessary to repeal or complement the scope of over-burdened work(MOL Notification) to prevent musculoskeletal disorders.

The industrial disaster caused by a work-related disease like a Musculoskeletal Disorders(MSDs) becomes a big social problem and increases rapidly. This leads to the degradation of the labor desire and the productivity. Welding work belongs to the work with a high intensity. This paper aims to analyze the welding work in the various positions from a view-point of the burden of the human musculoskeletal system and to propose the desired position with lower burden. For this purpose the real welding work was observed in the shipyard and analyzed using the RULA method, a powerful ergonomics tool. The 3-dimensional simulation model fur this work was also developed. In this model, ergonomics human model and welding work environment were built. This model was verified through the comparison to the real work. This paper showed that the improvement of welding position by changing the location of a stool and using some auxiliary tool can reduce the work intensity remarkably and lead to the decrease of MSDs.

Objectives: Sahrmann, an American physical therapist, has developed a set of movement-related diagnoses on musculoskeletal pain syndromes (MPS). We reviewed articles for studies of objectification and quantification of Oriental medicine diagnosis system about MPS. Methods: The authors reviewed a total of 12 studies found on PubMed to obtain movement system impairment (MSI)-based classification categories. Results: The MSI system has been developed for objectification and quantification of physical therapists' MPS diagnoses. The MSI system of classification is based on the basic premise that loss of precise movement is the result of specific repetitive movements and positions in everyday life. The MSI system defines 8 categories in the shoulder region, 5 in the lumbar region, and 7 in the knee region. Treatment involves (1) educating the person about the specific directions of alignment and movement that appear to be contributing to the musculoskeletal problem, (2) modifying the direction - specific alignment and movement patterns during daily activities, and (3) exercises to address the impairments. Conclusions: The authors propose that MSI studies could help to advance an Oriental medical diagnosis system on musculoskeletal pain syndromes, because MSI shares similarity with Oriental medicine in terms of holism, views of constant motion, and mi-byung (subhealth) treatment.
