Purpose: This study was to analyze the factors that affect the service relationship of long term care workers for the elderly and to provide basic resource for the successful connection of long term care services. Methods: 259 subjects who were engaged in long term care units completed a self-administered questionnaire that measured the extent of service linkage among one another. The Cronbach's ${\alpha}$ score determined the internal consistency of the acquired data and the discriminated validity was estimated by Pearson's correlation coefficient. Multiple regression analysis was conducted to investigate the influence of the known factors on the service linkage. Results: Acceptance and participation negatively influenced on the service linkage. Reliance, comprehension, recognition on service, and frequent contact with others positively activated the service linkage of long term care workers. Conclusion: The establishments of systemic training courses providing education that emphasizes reliability and recognizes other services, including work environment to contact easily are needed to improve the service-linkage of long-term care workers for the elderly.

Purpose: The purpose of this study is to analyze the hand functions of elderly persons according to their cognitive status and age. Methods: A total of 65 persons voluntarily participated in the study. The subjects were divided into three groups: impairment cognitive group, normal cognitive group, adult group (persons in their twenties). Assessment of cognitive status was performed using a mini-mental state examination for Koreans (MMSE-K). Hand function was assessed using the Purdue pegboard test. The collected data were analyzed using a one-way ANOVA and Pearsonn Acorrelation. Results: There were significant differences in hand functions in the three groups. Post-hoc test results showed significant differences between each group. There were statistically significant differences in the correlation among hand functions, cognitive status, and age. The findings of this study suggest that hand functions have a positive correlation with cognitive status. However, a negative correlation was found between hand function and age. Conclusion: According to the study's results, hand functions are correlated with age and cognitive functions in elderly persons. This study suggests that hand rehabilitation with cognitive intervention increases hand functions in elderly persons.

Purpose: The purpose of this study was to identify motivational factors that may influence health behaviors of patients with coronary artery disease. Methods: Structured questionnaires were used with a convenience sample of 164 subjects who were discharged from the hospital. The subjects were recruited for an interview at outpatient clinic in hospitals. The tools for the study were the motivational factors and health behaviors measure for the Elderly with cardiovascular disease. The data were analyzed using frequency, t-test, ANOVA, sheffe, Pearson correlation coefficient and stepwise multiple regressions. Results: There were significant correlations between motivational factors and health behaviors, ranging from r=.192 to .692. Stepwise multiple regression analyses indicated that 51% of variance in health behaviors was explained by self-efficacy and perceived benefits among four motivational factors(F=34.988, p<.01). Self-efficacy contributed the greatest amount of variance in health behaviors(${\beta}=.467$), followed by perceived benefits(${\beta}=.235$). Conclusions: The results of the study indicate that motivation, especially self-efficacy, was very important in predicting health behaviors of patients with coronary artery disease. Thus it would be necessary to include motivational factors in designing rehabilitation program for people with coronary artery disease.

This study was designed to examine a 3-week modified constraint-induced movement therapy (CIMT) to the less-affected arm of patients with Parkinson's disease (PD) would improve function of the more-affected arm in PD. The subjects were 6 institutional older adults with PD and clients of the social welfare facilities. The subjects (2 men, 4 women) ranged in age from 66 to 90 years (mean age 77.2 yrs). Three clinical tests were used to determine the improvement of functional activity between before and after modified CIMT. The tests included Unified Parkinson's Disease Rating Scale (UPDRS). Wolf Motor Function Test (WMFT), and Action Research Arm Test (ARAT). There were significantly differences after the modified CIMT for time performance in WMFT and pinch in ARAT (p<.05), No significant difference was noted after the modified CIMT for UPDRS and functional ability scale in WMFT. Therefore, the modified CIMT might improve time performance and is available to therapeutic program helping them improve functional ability for upper extremity in Parkinson's disease.

In this paper, we propose a system that can perform dumbbell exercise by recognizing the weight of dumbbells without wearing and device. With the development of virtual reality technnology, many studies are being conducted to simulate the pysical feedback of the real world in the virtual world. Accurate motion recognition is important to the elderly for rehabilitation exercises. They cannot lift heavy dumbbells. For rehabilitation exercise, correct body movement according to an appropriate weight must be performed. We use a machine learning algorithm for the accuracy of motion data input in real time. As an experiment, we was test three types of bicep, double, shoulder exercise and verified accuracy of exercise. In addition, we made a virtual gym game to actually apply these exercise in virtual reality.

Objective: This study aimed to evaluate the validity of a depth camera-based system for monitoring physical function, assessing its feasibility for accurately monitoring activities of daily living. Design: A cross-sectional study. Methods: Twenty-three participants were enlisted to perform fifteen activities of daily living within a living laboratory designed to simulate a home environment. Activities were monitored using a depth camera system capable of classifying actions into standing, sitting, and lying down, with a conventional video camera employed for activity recording. The duration of each activity, as measured by the system, was compared to direct observations made by a physical therapist which were analyzed using a motion analysis software. The association between these two measurement approaches was assessed through correlation analysis, coefficient of determination, intraclass correlation coefficient (ICC), and Bland-Altman plots. Results: Our findings indicated that standing activities exhibited the highest correlation (r=0.847) between the system measurements and physical therapist observations, followed by sitting (r=0.817) and lying down (r=0.734), which demonstrated lower correlations. However, the ICC and Bland-Altman plots revealed notable variances between the two measurement methods, particularly for activities involving lying down. Conclusions: In this study, the depth camera-based physical monitoring system showed promise feasibility in distinguishing standing, sitting, and lying down activities at home environments. However, the current study also underlined some necessities of enhancements in capturing lying down activities.

Objectives: This study was aimed to inspect what relation there exists between the elderly's social support, self-esteem and the suicidal thinking, and examined factors influencing their suicidal ideation. Methods: For 207 old persons above 65 residing at Seoul, questionnaire survey was performed for 4 weeks. For response data, t-test and ANOVA, Pearson's Correlation Coefficient and Multiple Regression Analysis were performed using spss 18.0 program. Results: The results of analysis are like followings. 1. As for the social support according to the general characteristics, there was statistically significant difference in sex distinction, religion, living arrangement, educational level, monthly allowance and mode to use spare time. As for self-esteem according to the general characteristics, there was statistically significant difference in sex distinction, religion, living arrangement and monthly allowance. And as for the suicidal ideation, there was statistically significant difference in the marital status. 2. As for the relation between the social support, self-esteem and the suicidal ideation, it showed statistically very significant positive correlation in the social support and self-esteem. And there existed relatively higher positive correlation in family support among sub-factors of the social support and the positive self-recognition among sub-factors of self-esteem. 3. It showed that positive and negative self-recognition as sub-factors of self-esteem, others' support as sub-factor of the social support influence on the suicidal ideation. In other words, as positive self-recognition was lower, as negative self-recognition was higher, as social support of others was lower, they had much more effect on the suicidal ideation of the elderly. And it showed about 36.1% of the explanatory capability. Conclusions: Health care providers should develop school health education for the elderly.

Purpose: This study aimed to compare balance ability according to the immersion level of virtual reality-based training for the balance enhancement of the elderly. Methods: This study included 48 elderly people aged 65 years and older (male 16, female 32). According to the immersion level of applied virtual reality training, 16, 17, and 15 persons were randomly assigned to full immersion, semi-immersion, and control groups. The subjects who were assigned to the full immersion group and semi-immersion group received virtual reality training for 6 weeks at 20 min at a time, 3 times per week. The control group received no intervention. Balance ability was evaluated by measuring the stability limit and the tandem walking test before and after the intervention. Results: Results showed significant differences among the three groups in the limit of stability of all directions and the tandem walking test after the intervention. The results of the limit of stability showed a significantly higher value in the full-immersion group than in the control group, and the results of the tandem walking test showed a significantly lower value in the full-immersion and semi-immersion groups than in the control group. Conclusion: The results indicate that the head-mounted display equipment for applying full-immersion virtual training is the most effective in enhancing the balance ability of the elderly.
