The PT program provides relief to most patients with symptom of TOS. So the purpose of our study is to evaluate a effects of PT program in patients with TOS. PT program included orthopaedic manual therapy with the aim of restoring the function of the upper thoracic aperture is to be recommended, and long-term following is advisable. 1. Mean treatment duration was over an 11.4 day(range 4~24). 2. At the follow-up evaluation, 88.1% of the patients were satisfied with the effects of their therapy. 3. 73% of the patients returened to work after PT and 88% of the patients carried through the recommendations given at discharge during follow up. 4. Normalized grip strength and Tinel' sign predicted patient satisfaction(p< .001) and return to work(p< .001). 5. Return to work was more often successful if the work was sedentary rather than heavy (p< .05).

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.

Background: A variety of sociodemographic factors, such as gender, age, household income, and educational level, influence individuals' likelihood of smoking.Work-related factors may also be linked to smoking behavior.We sought to investigate the relationship between smoking and work environment in South Korea. Methods: We analyzed data from the Fifth Korean National Health and Nutrition Examination Survey to determine whether there was an association between smoking and occupation type (e.g., manual, nonmanual, or service work), night-shift work, and hours worked/week (e.g., <40, 40-48, 49-60, or >60 hours) for 4,685 workers. Regression models were adjusted for sociodemographic variables such as age, recent alcohol consumption, hours slept, educational level, and household income. Results: The prevalence of smoking was 50.1% in men and 7.2% in women. For women, manual workers had 2.34 times [95% confidence interval (CI): 1.02-5.36] greater odds of smoking compared with nonmanual workers, whereas service workers had 2.37 times greater odds (95% CI: 1.28-4.40). Furthermore, women who worked 49-60 hours had 2.21 times greater odds of smoking (95% CI: 1.10-3.75) as compared with women who worked 40-48 hours. Conclusion: Women who work long hours or who are employed in service or manual positions are more likely to smoke. These results indicate a need in South Korea to target these specific groups when creating nonsmoking policies.

This study aims to find the way how to operate cataloging work effectively and share it between libraries through web based cataloging manual. There have been various trials in using web based tools in ether parts of library such as acquisition and reference service. However, in case of cataloging. the rules and policies of each library are not united. and any cooperation In sharing them between libraries is not done. Therefore. for Information sharing, practical cooperation and unification in cataloging work, each library needs to make web cataloging manuals and share them. That is, building the web based cataloging tools makes it easier to access the cataloging works and keep them updated. Additionally, it could improve the communication between the librarians who are in charge of cataloging and provide the chance for cooperation and information sharing between libraries. With these roles, web based cataloging manual could be the basic for standardization of cataloging.

Background: The purpose of this study was to develop a problem-based learning model for orthopedic manual physical therapy. A problem-based learning (PBL) model for orthopedic manual physical therapy developed from PBL module of Jeju C university (Halla-Newcastle PBL Center). A summary of this study is as follows: 1) PBL model is comprised of a class of 30 students, operated small group as of 4~5 students. 2) PBL is suggested a scenario of clinical case, induced variety reaction through group discussion and presentation. 3) PBL is occurred wide variety learning through group work activity and self-directed learning. 4) The tutor as a facilitator is played a guide for group discussion, work activity and team learning. 5) The evaluation for PBL is performed such as student self-evaluation, group activity evaluation, individual presentation, and practice. This model is considered wide variety learning through team learning and self-directed learning by clinical reasoning and problem solving for musculoskeletal clinical case. We suggest problem based learning for the education of orthopedic manual physical therapy in which the learners are very interested in and has the effective outcome.

Purpose: The National Institute for Occupational Safety and Health (NIOSH) lifting equation (NLE) is a useful tool to ergonomically analyze a workload. The NLE has high reliability and it can assess tasks by analyzing the work process. The purpose of this case study was to try using the NLE to analyze the workload of transferring patients by physical therapists in the hospital setting. Methods: We observed a physical therapist (PT) transferring patients from a wheelchair to a tilt table and a therapeutic table in one day. Two types of patient transferring methods were evaluated; (1) the manual single person method of stand, pivot and transfer, and (2) manual two person lifting under the thigh and grasping the waist for totally dependent patients. Results: The NIOSH lifting indexes of a person grasping the waist during the manual two person lifting were 5.52~4.48 according to the patient's weight. The NIOSH lifting indexes were 3.34 and 4.48 for the tasks performed by the manual single person method. Conclusion: Because transferring patients is not done very frequently, patients transferring tasks by a PT are not included as one of the musculoskeletal disorder related risky work criteria of the Korea Ministry of Labor. But the NIOSH lifting indexes of a person grasping the waist during the manual two person lifting and the manual single person method were over the NIOSH recommended weight limit threshold.

The objective of this study was to investigate the effects of carrying postures and weight of load carried one time on a worker when carrying heavy loads. Six male students participated in this study to perform a manual materials carrying task as subjects. To make comparison of work loads with physical work capacity, maximal oxygen uptake measurement tests were performed with submaximal test. The average oxygen consumption for the tasks of this study was 27.59~31.93% $VO_2$max. The results showed that the weight of load carried one time affects on working heart rate and oxygen consumption($VO_2$). It was found that the workload was significantly lower when handling a 20kg load at a frequency rate of 3times/min than when handling a 40kg load at a frequency rate of 1.5 times/min. There was no difference between carrying postures. It is concluded from the results of this study that the workload can be reduced by controlling conditions of a manual materials handling task.
