Objectives: The aim of this study is to evaluate the association between shiftwork and skeletal muscle mass index in a single university health check-up. Methods: We used data from 98,227 workers who answered in a special interview on health check-up at a local university hospital from 2014 to 2020. Pearson correlation analysis was conducted for comparing the association between skeletal muscle mass index and demographic and hematological variables in shiftwork and non-shiftwork groups. Mixed linear model analysis after controlling demographic and hematological variables was used to analyze the difference of skeletal muscle mass index between groups at every visit for seven years. Results: In linear regression analysis, the variables most significantly correlated with skeletal muscle index in both groups were shiftwork(p=0.049), BMI(p<0.001), hypertension(p=0.024), platelet(p<0.001), total protein (p<0.001), AST(p=0.028), ALT(p=0.003), ALP(p<0.001), total cholesterol(p=0.002), triglyceride(p=0.019), BUN (p=0.001), creatinine(p<0.001), and uric acid(p=0.002). After the adjustment for demographic and hematologic variables, the skeletal muscle mass index at every visit was decreased both in the shiftwork group and non-shiftwork group. The slope of the shiftwork group was -0.240 and non-shiftwork group -0.149, showing a significant difference (p<0.001). Conclusions: In the shiftwork group, the skeletal muscle mass index showed a tendency to decrease markedly over time compared to the non-shiftwork group. It is presumed that shift workers' skeletal muscle health was adversely affected by changes in the biological clock due to changes in wake-up and sleep patterns, and changes in food intake.

To overcome obstacles and to attain the goals of practical training for the students in the department of physical therapy it is necessary to effective an effective system for practical training. And to develop a good System it is essential to monitor the response of the students in practical training of physical therapy and to gather fundamental data. The author made up a questionnaire to the students in the department of physical therapy after the end of practical training course. The questionnaire consisted of 13 questionnaire for the general characterisitcs of the students, 19 questions for the degree of satisfaction (4 for the environment of practical training, 4 for the environment of practical training, 4 for the content 3 for the time assignment and 4 for the evaluation) and one open question. As results the students were satisfied with the practicality and fresh experience. But they were relatively unsatisfied with the environment of the practical training and the number and sincerity of the trainers. Especially they were dissatisfied with the correspondence with the objectives of education, conection with the lecture, communication with the trainers, time assignment and evaluation. As a Part of efforts to formulate an effective system fer practical training it is necessary to estabilish concrete goals and detail check lists to guide both trainers and students.

This study was designed to develop preventing occupational disease programme in small-medium scale industries. The intervention was done in 354 enterprises from July to December in 1993 by health personnels in mobile occupational health centers. The summarized results of the above achievements were as follows. 1. Total number of enterprises were 354. Among them $66.9\%$ was under 100 workers, $26.6\%$ was u!1der 200 workers, and $6.5\%$ was belong to over 200 workers. The majority manufactures were non-metallic mineral product industries $(11.3\)$ fabricated metal product industries $(11.0\%)$. and textile industries $(10.7\%)$. 2. In 1993, for 350 enterprises were carried out evaluation of workplace environment. A total of $76.3\%$ industries were found to improper showing higher level of hazardous agent than the TLV. Noise and dust are the typical agent of which levels in workplace were high in most of industries. 3. A total 60 cases $(0.8\%)$ of occupational diseases were detected through physical check-up from 7,394 industrial workers in 1993. Detection rate by hazardous agent was highest among workers in relation to dust, and secondly highest to noise. 4. Through the systematic approach by hazardous agent was increased to the monitoring of work condition and follow up care of occupational disease. In future, there should be development in the scaled check list of preventing occupational disease management.

Regular dental visit of disabled patients is an important strategy for maintenance of oral health because of the lack of awareness of oral care. But there is limited information about follow up period in disabled patients after dental treatment. The aim of this study was to investigate the pattern of dental visit and dental management of special care needs patients according to the types of disabilities. A total of 140 patients who received dental treatment at Seoul National University Dental Hospital from 2010 to 2012 were reviewed. Patients were divided 3 groups according to the types of disabilities (disorder of external physical function, disorder of internal organ, psychic disability). Patient's characteristic, dental treatment performed, follow up period and frequency were investigated. The mean follow up period was 28.2 months and average frequency of visit was 3.69 times per year. There was no difference in period and annual visit between 3 groups, but significantly difference in cooperation with medical hospital in affiliation. Regular check-up was the most common dental treatment in all groups. In psychic disorder group, the proportion of sedative treatment was significantly higher than other groups. The results of this study provide information necessary for treatment planning and dental management of disabled patients.

Purpose : The purpose of this study is to check the current status of accessability to rehabilitation therapy in local areas and to review how to improve the accessability. In fact, first, it is very hard for patients to find out a local medical center with rehabilitation therapy capability. Moreover they needs to wait long time to get a treatment they need, because of lack of nearby rehabilitation centers. The best way to enhance the accessability to the rehabilitation therapy service is to allow therapists to set up rehabilitation centers in local areas on their own, physically independent from medical doctors. Basically, the current law does not prohibit therapists' own sole practice. However, it needs to be amended by inserting an explicit legal basis on the setting-up process. If it is legally permissible for the therapists to set up rehabilitation centers to perform a rehabilitation treatment with referrals from of medical doctors (though physically independent from the doctors), it would result in the increase of profits for the doctors and at the same time raise therapists' freedom of occupation, a constitutional right. Furthermore, with their own places to practice, therapists will have to compete with other therapists, that would raise the quality of their treatments, which will in turn benefit patients ultimately. A proposed bill of amendments to the Act on Medical Technicians and etc. is pending for review at the National Assembly. I look forward to vigorous discussion on the bill based on this article, and resulting in revision of the law for the benefits of patients.

Researches on after-sales quality have centered on home electric appliances, figuring out how factors influencing after-sales service quality are causally related to customer's behavioral intentions, via consumer satisfaction as an intermediary parameter In most cases of after-sales service in home electric appliances, upon customer's request, service agents make a visit to where the appliance is installed, and check the product and do repairs. However, in case of a small portable device such as a cell phone, which people carry around at all times, most of the times customers themselves show up at the after-sales center, and demand a check-up and repairs. The main difference here is that the after-sales services are provided when a product can no longer perform its basic function and customer dissatisfaction is already up. In this case, the basic function of a product corresponds to must-be factor according to Kano model. The goal of our research is to identify critical factors for effective and efficient after-sales service, and how to monitor them on a routine basis. In our research, the quality after-sales service consists of three dimensions, interactive quality, result quality, and physical environment quality. We set up variables for each dimension, which would measure from customer's perspective key determining factors in service delivery process. Instead of focusing on customer satisfaction aspect, we focused on how after-sales service factors contribute to addressing customer complaints. Additionally, our future research would aim to verify how customer's behavioral intentions are affected, as the resolution of consumer complaints becomes more successful when adjustment of relevant quality factors improves after-sales service quality.

The differential quantum chromodynamics (QCD) predictions for the $W^{\pm}$ boson and a single jet as functions of the lepton pseudorapidity in proton-proton collisions are presented up next-to-leading order correction in QCD. The predictions are done by using the most modern parton distribution functions (PDFs). To check the reliability of the PDFs, we compared 7 TeV predictions with the available experimental results at the corresponding energy. Finally, the differential QCD predictions and the asymmetry between the $W{^+}+1$ jet and $W{^-}+1$ jet events at $\sqrt{s}=7$, 8, 13, 14 and 100 TeV are discussed in detail.

This study was undertaken to obtain information about selected characteristics and the degree of physical disability of patients with a diagnosis of cerebrovascular accident upon their discharge from a general hospital. It was hoped that this information would contribute to the assessment of their needs for follow-up nursing care. Nurse's and Physician's Progress Notes of all stroke patients discharged from five general hospitals in Seoul from January to December 1975 were analysed using a prepared check list. Patients with other complicating diagnosis such as diabetes, tuberculosis or heart disease were excluded from the sample. According to six factors used to grade the total sample of 334 stroke victims degree of physical ability at discharge, 144 (43%) of the Survivors had good functional ability, 72 (22%) fair, 62 (18%) poor, and 57(17%) very Poor. Certain clinical diagnosis correlated with the degree of physical ability. Intra cranial Hemorrhage and Subarachnoid Hemorrhage tended to be related to poor and very poor outcome categories. There was no significant correlation between nae and ability outcome, women had revealed a significantly positive correlation with poor and very poor ability outcomes. The hospitalization period was less than three days for 37.5% of the total group, and more than one month for 4.7%. Those patients with less than three days hospitalization accounted for the highest relationship with poor and very poor ability outcomes. Of the total groups 175(50.99%), were discharged with a diagnosis of condition improved (though not necessarily with good physical ability). The results suggest serious need for comprehensive follow- up nursing care for stroke survivors discharged a from general hospitals in Seoul.

Purpose: Myofascial syndrome is a chronic muscle pain caused by repetitive motions with stress-related muscle tension. This study aimed to investigate the validity and reliability of the evidence for diagnosing myofascial pain syndrome in trapezius muscle using a pressure algometer and surface electromyography. Methods: The experiments were performed using a total of 10 subjects, and the target locations were determined by means of a pressure algometer in the right upper trapezius muscle. The part with the lowest pain value as the trigger point and the part with the highest pain value as the non-pain trigger point were selected for measuring the locations. The median frequency and average frequency were measured in those locations with electromyography. To check the muscle fatigue, the upper trapezius muscle was moved up and down for 2 seconds at 5-second intervals in 30 seconds. The measured values were evaluated using the independent paired t-test and MannWhitney U-test. Results: The median frequency at the non-trigger point (13.7) was significantly higher than that at the trigger point (7.3). Furthermore, the mean frequency (14.7) at the non-trigger point was significantly higher than that at the trigger point (6.3). Conclusion: The results showed the correlations between the trigger points of the muscle pain and frequency analysis of surface electromyography. Thus, this study may be possible to use as a diagnostic tool for myofascial pain syndrome.

PURPOSE: This research was designed to study the correlations between physical activities such as foot sensory impairment, balance and ambulatory abilities, as well as fall risk factors and mental activities such as cognitive performance and depression in order to provide fundamental data for the prevention of falling in the elderly. METHODS: A total of 36 elderly people over the age of 65 years who voluntarily joined the research were selected as subjects. Sensory perception in both feet was measured by using a monofilament in 10 parts with each part given one point. The points for each foot were integrated to analyze the correlations between physical and mental activities indices, and the results were analyzed by using Pearson's correlation coefficient. RESULTS: The results of this research show that the extent to which senses in feet were impaired was correlated to TUG, a functional activity index involved in tranfers, gait, and turning movements, which was correlated to BBS (balance index) as well as MMSE-K and K-GDS (mental activities index). BBS was interrelated to FES-K (physical activities index) and MMSE-K. The muscular strength of the right ankle dorsiflexor had mutual relations with FES-K. CONCLUSION: The results of this research indicate that TUG is widely correlated to foot sensory impairment as well as general physical and mental activities in elderly people. BBS was also shown to be correlated with TUG, FES-K, and MMSE-K. Thus, it might be necessary that TUG and BBS be included as two items in physical and mental check-ups for the elderly, and further studies on correlations using evaluation items for physical and mental activities should lead to the simplification of the evaluation criteria.
