Objective : This study aims to contribute to developing improved strategies for the rehabilitation programs of stroke patients by analyzing the relationship between obesity, relative grip strength, subjective health status, and health-related quality of life in stroke patients. Method : A secondary analysis was conducted on 651 stroke patients among the raw data from the 6th, second year(2014) to the 8th, first year(2019) of the National Health and Nutrition Examination Survey, in which the grip strength test was conducted. Obesity, relative grip strength, subjective health status, health-related quality of life, and control variables of stroke patients were selected and the relationship between each variable was analyzed. Result : The main results of this study are: First, factors affecting health-related quality of life included subjective health status(β=0.39, p=0.00) and relative grip strength(β=0.28, p=0.00), and obesity have no significant effect. Second, it was confirmed that the interaction between relative grip strength and body mass index showed a positive relationship with health-related quality of life after adjusting for sociodemographic and health behavior factors(β=0.27, p=0.00). Third, the group with high relative grip strength had a significantly higher health-related quality of life than the group with low relative grip strength(F=14.78, p=0.00). Fourth, the group with good subjective health status had significantly higher health-related quality of life than the group with poor subjective health status (F=12.64, p=0.00). Conclusion : Since relative grip strength is a major factor in evaluating the subjective health status and health-related quality of life of stroke patients, an intervention program through strength training, including grip strength training, was attempted to improve the quality of life for patients whose quality of life is expected to decline. In addition, the application of differentiated intervention programs according to the size of relative grip strength in obese group can be a way to improve the health-related quality of life of stroke patients.

Objective : This study attempted to identify differences in performance in daily life activities and participation in leisure activities according to grip strength for the elderly by age and gender group in Korea, and to present basic data on the actual conditions of the elderly in Korea. Methods : Based on the 8th year survey data of the Korean Longitudinal Study of Ageing (KLoSA) collected from August 2020 to December of the same year, 3,789 elderly people over 65 years of age were targeted. The elderly were divided by gender, age, dominant hand, and non-dominant hand to check the grip strength, the degree of performance of basic activities of daily living and instrumental activities of daily living, and the degree of participation in leisure activities, and the relevance of each variable was analyzed. Continuous variable analysis by grip strength for the elderly was analyzed using an independent t-test. Results : In the difference in activities of daily living by the grip strength, there was a significant difference in instrumental activities of daily living of both men and women over the age of 75 (p<.05). The elderly under the age of 75 showed no significant difference by the grip strength in both activities of daily living and instrumental activities of daily living (p>.05). In the difference in leisure by the grip strength, there was a significant difference in the number of travel, tourism, and outing experiences for men of all ages and women aged 75 to 84, and there was a significant difference in the viewing number of movies, performances, concerts, exhibitions, and sports games for men aged 75 to 84, and for women aged 65 to 74, there was a significant difference in the time to participate in hobbies and entertainment-related meetings or programs for women aged 75 to 84 (p<.05). Conclusion : Since the elderly with high grip strength were found to have high activities of daily living and leisure, efforts to improve grip strength are needed to improve the elderly's daily functions.

Objective : The purpose of this study was to investigate the effects of Life skills occupational therapy program on the improvement of psychotic symptoms, functional performance, social functions, and performance capacity of daily activities in chronic schizophrenia patients. Methods : It was conducted on 19 patients registered at the Mental Health Welfare Center. The program applied to the study group was developed overseas and was modified and supplemented according to the domestic situation and was conducted once a week for 75 minutes, a total of 16 times. Results : As a result of comparing before and after the program, the study group showed a significant effect on psychotic symptoms, functional performance, social functions, and activities of daily living. Control group was a significant difference in some part of social functions, but there were no significant differences in other areas. When comparing the changes between the groups after the program, there were significant differences in positive symptoms and overall symptoms, which are subtypes of psychotic symptoms. Conclusion : In this study, it was confirmed that there was a positive effect on symptom improvement and performance capacity of daily activities as a result of applying Life skills occupational therapy program to patients with chronic schizophrenia living in the community.

Objective : The purpose of this study was to identify the factors influencing the quality of life of stroke elderly. Methods : The number of samples was calculated using the G*Power 3.1 program, and the study was conducted on a total of 164 elderly stroke patients. The 2019 National Statistical Office's Living Time Diary was used to evaluate the study subjects' time use, and the World Health Organization Quality of Life-BREF evaluation tool was used to evaluate the quality of life. Pearson's correlation coefficient and multilinear regression analysis were performed to identify variables that can predict the quality of life of the study subjects' time use. Results : The results of this study can be divided into two main categories. First, a correlation analysis of variables affecting the quality of life was conducted, and as a result, instrumental activities of daily living (r=.367, p<.001), leisure (r=.315, p<.001), and social participation (r=.205, p<.01) showed a positive correlation, while rest and sleep (r=-.396, p<.001) showed a negative correlation. Second, as a result of analyzing the causal relationship between time use and quality of life, the F value (21.386), which represents the model's suitability, was statistically significant (p<.001), and the modified coefficient of determination (Adj. R2) representing the model's explanatory power was found to explain 20% of the quality of life by rest and sleep (B=-.002, p<.001) and activities of daily living (B=-.002, p<.01) Conclusion : Balanced time use is significantly correlated with quality of life of the elderly with stroke. Providing opportunities to actively participate in a variety of tasks should be considered when approaching occupational therapy interventions to improve quality of life of the elderly with stroke.
