This study was conducted for the purpose of obtaining basic information on the patterns of medical care expenditures, and identifying some determinants of medical care expenditures in the rural Korea. Nine guns were chosen from the eight provinces, excluding Cheju island. One gun in each province and two villages were selected from the each myon or ub within the selected guns. The total number of households was 1,789 and the sample size was 9,826 non-institutionalized people. Followings are the major findings of the study : 1) Medical care expenditures increase proportionally with age in terms of cost per patient, per episode of illness, per treated case, and per person. Averagely, it cost 2,756 won per patient, 2,614 won per spell of illness, 4,361 won per treated case, and 413 won per person. 2) Medical care expenditures increase proportionally with educational level of patients. College graduates spent the most, 4,726 won per patient, 5,987 won per treated case, and 670 won per person. 3) The male spent a little more than the female in terms of per patient, per episode, and per person. For example, a male spent 23 won more than a female. 4) Those who were suffering from illnesses longer than 1 year spent three times more than that had illnesses of less than 1 year duration. 5) The simple correlation coefficient between activity restriction and medical care expenditures was the highest among others, 0.491. The next was 0.294 between duration of illness and medical care expenditures. 6) Attempts are made to identify the explanatory variables in medical care expenditures. Thirty one per cent of the variances in tile expenditures can be accounted for by the selected 15 predictors. Those predictors belonged to clinical renditions, such as activity restriction, duration of illness, and nature of conditions, are proved to be the most potent independent variabes. Level of education and monthly family income are also significant in terms of beta coefficient. Further studies are called for to unreveal the determinants of medical expenditures.

Shoulder pain, injury and discomfort are public health and economic issues world-wide. The function of these joints and the stresses developed during their movement is a major concern to the orthopedic surgeon to study precisely the injury mechanisms and thereby analyze the post-operative progress of the injury. Shoulder is one of the most critical joints in the human anatomy with maximum degrees of freedom. It mainly consists of the clavicle, scapula and humerus; the articulations linking them; and the muscles that move them. In order to understand the behavior of individual muscle during abduction arm movement, an attempt has been made to analyze the stresses developed in the shoulder muscles during abduction arm movement during the full range of motion by using the 3D FEM model. 3D scanning (ATOS III scanner) is used for the 3D shoulder joint cad model generation in CATIA V5. Muscles are added and then exported to the ANSYS APDL solver for stress analysis. Sensitivity Analysis is done for stress and strain behavior amongst different shoulder muscles; deltoid, supraspinatus, teres minor, infraspinatus, and subscapularies during adduction arm movement. During the individual deltoid muscle analysis, the von Mises stresses induced in deltoid muscle was maximum (4.2175 MPa) and in group muscle analysis it was (2.4127MPa) compared to other individual four rotor cuff muscles. The study confirmed that deltoid muscle is more sensitive muscle for the abduction arm movement during individual and group muscle analysis. The present work provides in depth information to the researchers and orthopedicians for the better understanding about the shoulder mechanism and the most stressed muscle during the abduction arm movement at different ROM. So during rehabilitation, the orthopedicians should focus on strengthening the deltoid muscles at earliest.

^x This study was executed to measure the user's psychological carrying capacity in the National Park Campsite in the district of Temple Ku- Ryong as a model of analysis, which is made socio - psychological approach. The results are as follows ; 1. Since this Place hart a beautiful scenery and some cultural assets prosperties and lies near the metroplitan area, 67.5% of the user come from the district, such as Seoul, Inchon, Kyong - Ki Do, and the purpose of camping is to appease their stress and to promote friendly relationship one another. 2. Since most of the campers(86%) didn't recognize the injury of the natural environment, the enlightment movement and the public information for the protection of natural environment are urgent. And they thought that the good campsite is located near the stream(43.6%) or a quiet place(33.4%). 3. As the space per a man increase, the degree of their satisfactions showed the tendency to increase. The user's satisfaction were analyzed by three statistic methods, correlation, multiple regression and factor analysis. Affecting factors to the user's psychology by the varimax varimax rotated factor analysis were classified physical arts ecological satisfaction. 4. The carrying capacity of the campsite by the degree of psychological satisfaction of the user was measured. The result was that the proper space for one user campsite was 35m$^2$ 5. The 58% of the informants said that they root disturbed by the overcrowding in the campsite. But most of the users thought that it was not good to control the number of the users. And the 67.3% of the respondents answered that the best method was that we control the number of the users by order of arrival if we have to control it.

With the introduction of the 40 hours workweek system, an intensive discussion was made among relevant departments. Building facilities does not necessarily guarantee more leisure activities and higher satisfaction for the public. It is essential to draft at the trend of leisure policy in Japan and learn from the experiences to set the policy direction best fitting future changes in Korea, as Japan has gone through comprehensive changes ahead of us. With this understanding, this study analyzed key leisure policies of Japan and examined the trend of changes of time. The followings are the findings of the research. First, Japan's leisure policies could be categorized into five stages and six terms. Second, leisure policies in Japan are being established as a local welfare system, not in the context of industrial perspective, to help people in local community. This is to make voluntary move by eliminating the factors that restrict social demand with an effort to expand leisure time and to secure and enhance access to leisure space. Third, Neighborhood leisure space has taken the center stage, in an effort to seek solutions to the issues of improving space utilization, restoring local community and encouraging participation of local residents. The conclusion drawn from the research is as follows. It is required to recommend the use of the specific term 'leisure' for leisure policies in Korea and for leisure space policies in Korea that are now facing sociocultural challenges similar to the ones emerging in Japan, measures are required to improve physiological access of local residents including information promotion, lifetime education and relationships enhancement along with the establishment of neighborhood leisure space.

Objectives : The purpose of this study was to provide some information on down-to-earth oral health policy to improve the systemic health involving oral health and the quality of life in Korean adults. Methods : The third-year data of the 4th National Health and Nutrition Survey in 2009 were analyzed, and $x^2$(Chi-square) test was carried out to see whether there would be any gaps in subjective oral health status according to demographic characteristics, systemic health state, frequency of eating between meals and oral health behavior. In terms of the DMFT index, one-way ANOVA was utilized, and then Scheffe post-hoc analysis was conducted. Besides, multiple regression analysis was made to grasp the relationship of oral health behavior to subjective oral health state and the DMFT index. Results : The demographic characteristics, systemic health status and oral health behavior had a significant relationship to both of subjective oral health status and the DMFT index. As a result of analyzing the relationship of oral health behavior to subjective oral health state and the DMFT index, the subfactors of oral health behavior exerted a significant independent influence on subjective oral health status and the DMFT index. Conclusions : The findings of the study suggest that in order to promote the oral health of adults, preventive measures should be taken, and systematic oral health education should be provided. As there is an increase in the elderly population in Korea, the successful implementation of senior oral health plans and the development of oral health programs geared toward adults are both required.

Objectives : The purpose of this study is to develop a job performance assessment tool for dental hygienists. Methods : The development consisted of three steps. The first step was to construct the contents of the assessment tool and a pretest questionnaire. In the second step, validity and reliability tests were done and modified for the pretest questionnaires and an assessment tool was made. The third step was verification of the assessment tool. A total of 678 data from the dental hygienists were analyzed to verify the validity and reliability. The assessment tool consisted of two areas such as job performance and competency/attitude: the job performance area covered four sub-areas including oral health education, preventive dental care, assistance for dental treatment, and administrative management. Results : The number of questions and reliability test result for each sub-area were as follows. Reliability coefficient for oral health education (10 questions) was 0.899, preventive dental care (8 questions) was 0.861, assistance for dental treatment (18 questions) was 0.915, administrative management (8 questions) was 0.919, competency of dental hygienists (11 questions) was 0.947, and attitude of dental hygienists (15 questions) was 0.955. Cronbach ${\alpha}$ coefficient for reliability of total 70 questions of the assessment tool was 0.980. Conclusions : The validity of the assessment tool was verified by three steps and the reliability proved to be significant. Consequently the assessment tool was found to be useful as an objective and valid job performance assessment tool for the dental hygienists.

Objectives: The aim of this study was to investigate whether a medium to high degree of total physical activity and indoor physical activity were associated with reduced all-cause and cardiovascular mortality among elderly Korean women. Methods: A prospective cohort study was done to evaluate the association between physical activity and mortality. The cohort was made up of elderly (${\geq}65$ years of age) subjects. Baseline information was collected with a self-administered questionnaire and linked to death certificates retrieved from a database. Cox proportional hazard models were used to estimate the hazard ratios (HRs) with 95% confidence interval (CI) levels. Results: Women who did not suffer from stroke, cancer, or ischemic heart disease were followed for a median of 8 years (n=5079). A total of 1798 all-cause deaths were recorded, of which 607 (33.8%) were due to cardiovascular disease. The group with the highest level of total physical activity and indoor physical activity was significantly associated to a reduced all-cause mortality (HR, 0.60; 95% CI, 0.51 to 0.71 and HR, 0.58; 95% CI, 0.50 to 0.67, respectively) compared to the group with the lowest level of total physical activity and indoor physical activity. Additionally, the group with the highest level of total physical activity and indoor physical activity was significantly associated to a lower cardiovascular disease mortality (HR, 0.53; 95% CI, 0.40 to 0.71 and HR, 0.51; 95% CI, 0.39 to 0.67, respectively) compared to the group with the lowest level of total physical activity and indoor physical activity. Conclusions: Our study showed that regular indoor physical activity among elderly Korean women has healthy benefits.
