지적장애인은 인지기능과 조정기술의 손상, 낮은 운동능력 등으로 인해 신체활동수준이 부족하고 음식섭취 욕구가 강하여 생활습관질환의 이환율이 높아 삶의 전 영역에 영향을 미친다. 안타깝게도 현대의학으로는 지적장애인의 삶의 질을 개선시키기에는 많은 어려움이 있다. 하지만 규칙적인 신체활동은 이러한 문제점을 개선시키는 중요한 중재로 인정되고 있다. 본 연구는 유희성과 중독성이 있는 가상현실 게임프로그램을 통한 운동프로그램과 일반적인 빠르게 걷기 프로그램을 통해 건강관련체력과 정신건강수준 등을 비교하였다. 중도탈락자를 제외하고 가상현실 게임운동프로그램군 5명, 빠르게 걷기 운동프로그램군 4명을 대상으로 비모수검증을 통해 비교분석하였다. 가상현실 게임바이크운동프로그램군의 체중, 근지구력 요소에서 유의한 개선이 있었으며, 모든 집단의 중성지방, 유연성, 최대산소섭취량, 운동지속시간에서는 통계적으로 유의하지는 않았지만 개선되는 경향을 보였다. 운동프로그램 전·후 우울, 사회적 부적응, 정신건강에서는 빠르게 걷기 운동프로그램군에 비해 가상현실 게임바이크운동프로그램군에서 유의하지는 않지만 개선되는 경향을 보였으며, 운동 흥미도가 높고, 자각인지도는 낮게 나타났다. 이는 게임기를 이용한 가상현실 운동프로그램의 적용이 게임으로 인한 부정적인 측면보다 운동으로 인한 긍정적인 면이 크다는 것을 의미하므로 지적장애인의 운동프로그램을 계획하는 데 적극적으로 활용할 필요가 있다고 판단된다.

Objective: The aim of this paper is to introduces Hyundai Heavy Industry's ergonomic risk assessment tool, H-OWAS, which is considering work load and frequency compared to the OWAS. Background: As prevalence of work-related musculoskeletal disorders(WMSDs) in ship building industries has been much higher than that in other industries, most of the large scaled corporations have implemented their own prevention program since legislation on the prevention of WMSDs had introduced in 2003. Method: This paper introduces WMSDs prevention program, HEMP(HHI Ergonomics Management Program) which consists of risk assessment, improvement efforts of working environments, medical treatment and training/evaluation and describes how to operate the program. We also describe application of OWAS method considering work load and frequency for risk factor analysis(H-OWAS) and shows methodology for assessing the ergonomic risk factor. And comparison of the assessment results between OWAS and H-OWAS is carried out by statistical analysis. Result: There was statistically significant difference in the assessment results between OWAS and H-OWAS, and regression shows H-OWAS explains the borg's scale of perceived exertion more clearly than OWAS. Conclusion: H-OWAS has been proved more effective tool than OWAS to evaluate ergonomic risk factor under real working condition. Application: H-OWAS can be widely applied to the many other companies when implementing the ergonomics risk assessment.

Purpose: This study was to develop and evaluate stability and effects of an early exercise program for patients with open heart surgery. Methods: The subjects of this study were 30 patients who had either a coronary bypass surgery or a valvular heart surgery at a tertiary hospital in Seoul. The data was collected by observation and measurement from October 1, 2004 to November 15, 2004. Results: The early exercise program developed for this study consisted of range of motion exercise and walking. Intensity of walking was 1~3 METs and increased progressively to daily target distance. During exercise, the subjects were monitored heart rate, blood pressure and RPE (Rating of Perceived Exertion). The mean FIM (Functional Independent Measurements) score of subjects was significantly improved after the early exercise program. However, several complaints such as dizziness or pain were also reported. Most complaints were associated with chest tube and RPE. Conclusion: The early exercise program can help to recover patients' physical activities after surgery, and can be applied to most patients. Patients' RPE, dizziness and pain was possible limitations, therefore, active pain control and prevention of accidents for patients would be needed.

PURPOSE: Improving elderly people's balance ability through pilates which may be easily applied in ordinary life is considered an important intervention method for elderly people. Therefore, this study examines the effects of pilates training on elderly people's static and dynamic balance abilities and provides clinical data to improve this ability. METHODS: The pilates program was applied to 19 elderly subjects three times per week for 8 weeks. Their training level took into consideration their age and was set so that the rating scales of perceived exertion became 13 to 14. Prior to the initiation of the experiment, the subjects had an adaptation period in order to practice the order and motions of pilates. After the adaptation period, the subjects received training. The program was conducted three times per week, for eight weeks. Their dynamic balance ability was observed through the timed up and go (TUG) test and tandem walk test (TWT), and their static balance ability was evaluated by the center of pressure (COP) area, medial-lateral displacement, and anterior-posterior displacement. RESULTS: The results of the TUG test and TWT and evaluations of the COP area and medial-lateral displacement were significantly different after the pilates exercise program compared to those before the program began. CONCLUSION: The results show that an 8-week pilates exercise program is an effective method to increase elderly people's static and dynamic balance abilities. In addition, the application result of the pilates exercise program will provide useful information for future research on elderly people's balance ability.

Purpose: The purpose of this study was to identify the time for young adults to reach resting blood pressure after walking as measured by an automatic and a mercury sphygmomanometer. Methods: Participants were 33 nursing students in their 20s. Blood pressure after walking was measured every minute on both arms simultaneously for a total of 6 times after walking for 12 minutes on a treadmill at ratings of perceived exertion (RPE) of 11. Data were analyzed using paired t-test, Bland-Altman plots and repeated measures ANOVA. Results: Systolic blood pressure after walking was the same as measurements corresponding to resting blood pressure after 3 minutes of resting if measured with the automatic sphygmomanometer and 4 minutes of resting if measured with the mercury sphygmomanometer. Conclusions: In order to measure the resting blood pressure for healthy young adults who performed low-density walking for 12 minutes on flat land, the measurement needs to be made after a resting time of at least 3 minutes in the case of an automatic sphygmomanometer and 4 minutes in the case of a mercury sphygmomanometer.

The purpose of this study was to compare the effects of underwater treadmill gait training (UTGT) and overground treadmill gait training (OTGT) on the gait, balance ability and pulmonary function of stroke patients. Twenty subjects were recruited for this study. The subjects were randomly assigned to two groups: UTGT ($n_1$=10) and OTGT ($n_2$=10). The 10 m walk test (10 MWT), Berg Balance Scale, Timed Up and Go (TUG) test, center of pressure, pulmonary function of forced vital capacity (FVC), forced expiratory volume after 1 sec (FEV1) and FEV1/FVC were measured before and after 4 weeks of training. Both groups undertook the gait training for 30 min a day, 3 times a week, for 4 weeks, and rating of perceived exertion of the groups were measured and compared. All the studied variables were significantly improved in both groups (p<.05) at the end of the study, except in the FEV1 of OTGT (p>.05). There was significant between-group difference in all of the variables, except in the 10 MWT (p>.05). These findings suggest that UTGT is more effective than OTGT in improving the balance and pulmonary functions of stroke patients.

Purpose: The aim of this study was to investigate whether job satisfaction in clinical nurses was dependent on work intensity and whether physical discomfort mediated the relationships between these variables. Methods: Structural equation modeling was used with a sample of 253 clinical nurses from four general hospitals. In the model, absolute work intensity, relative work intensity, and flexibility were considered as exogenous variables and physical discomfort as a mediating variable. Data were collected using self-report measures such as the Labor Intensity Questionnaire, the Rating of Perceived Exertion, and the Index of Job Satisfaction. Results: The results of the structural equation modeling found that the higher scores on absolute and relative work intensity were positively associated with physical discomfort but only relative work intensity was significantly related to job satisfaction. Physical discomfort mediated the relationships between absolute work intensity and job satisfaction and between relative work intensity and job satisfaction. Among three kinds of work intensity, only relative work intensity had direct and indirect effects on job satisfaction. Conclusion: The findings suggest that increase in relative work intensity might play an important role in decreasing job satisfaction in clinical nurses and a reasonable reward system considering relative work intensity could be necessary.
