Objective : This study aimed to identify the quantitative changes and trends in research topics related to vocational rehabilitation in Korea over time, thereby examining shifts in the domestic vocational rehabilitation paradigm. Methods : The study analyzed a total of 1,531 academic and thesis publications related to vocational rehabilitation, which were registered in the database of the Korea Education and Research Information Service (KERIS) by 2023. Quantitative analysis was conducted on the collected data, and general frequency analysis and keyword analysis, and topic modeling were applied to 938 documents that contained abstracts. For topic modeling, the Latent Dirichlet Allocation (LDA) algorithm was used to classify keywords. Excel, SPSS, and R were used for analysis. Results : The quantitative analysis revealed 904 academic papers and 627 theses. The Korean Society of Vocational Rehabilitation had the highest number of academic publications, while Daegu University produced the most theses. In the keyword frequency analysis of vocational rehabilitation studies, "job" had the highest frequency, followed by "persons with disabilities", "vocational rehabilitation", "rehabilitation facilities", "needs", and "society". Among the 11 main topics derived from topic modeling, "Topic 7: Return to Work for Injured Workers" was the most commonly discussed. The analysis of changes in research topics over time showed that "Topic 2: The Meaning and Value of Vocational Rehabilitation Based on Personal Experience", "Topic 6: Effectiveness of Vocational Rehabilitation Services", and "Topic 7: Return to Work for Injured Workers" have been steadily increasing, whereas "Topic 5: Personal and Social Efforts for Economic Independence", "Topic 8: Policy and System Improvement to Promote Employment of Persons with Disabilities", and "Topic 9: Vocational Training for Successful Employment and Job Retention" have been decreasing. Conclusion : This study confirmed that vocational rehabilitation can be defined as "achieving employment and satisfaction for persons with disabilities through rehabilitation facilities, social support, services, and programs", aligning closely with the goals and directions of occupational therapy. It was also found that the quantitative and qualitative changes in vocational rehabilitation research are closely related to the enactment and revision of national laws and policies.

Objective : This study aimed to provide basic data for finding ways to manage and promote the health of the elderly by analyzing the relationship between grip strength and the ability to perform activities of daily living in the elderly depending on whether or not they exercise regularly. Method : A secondary analysis was conducted on 5,192 subjects from the 9th (2022) Aging Research Panel Survey raw data. The relationships between the variables were analyzed by selecting the elderly's grip strength, basic activities of daily living, instrumental activities of daily living, regular exercise, and control variables. Result : The main results of this study were as follows: First, among the factors affecting the activities of daily living, the score was significantly lower for women, those under 75 years of age, those with a middle school diploma or higher, those with a marital status, and those without hypertension or diabetes, indicating a higher ability to perform activities of daily living (p<0.05). Second, the higher the grip strength, the lower the score of activities of daily living, and there was a negative correlation in the correlation analysis (r=-0.60, p=0.00), and in the multiple regression analysis, the grip strength was found to have a negative effect on the score of activities of daily living (β =-0.06, p=0.00). Third, even when controlling for demographic factors, health behavior factors, and regular exercise, it had a negative effect of 11-14% on the scores of basic and instrumental activities of daily living (p<0.05), confirming that the higher the grip strength, the higher the ability to perform activities of daily living. Fourth, the group that exercised regularly had significantly lower scores on activities of daily living (p<0.05), and in particular, in the 1st quartile group with the lowest grip strength, there was a significant difference in the scores on activities of daily living depending on whether or not they exercised regularly, indicating that regular exercise had a greater effect on the ability to perform activities of daily living when grip strength was low. Conclusion : In order to improve the elderly's ability to perform activities of daily living to enhance their independence, it is thought that developing an intervention program that allows them to participate in regular exercise in their daily lives, along with grip strength training, could be one strategy for improving the elderly's ability to perform activities of daily living.

Objective : The purpose of this study was to analyze how physical activity, sleep, and mental health, which are generally seen in elderly stroke patients, affect the quality of life of individual patients and to provide basic data for the development of a community rehabilitation intervention program. Methods : We analyzed the amount of physical activity, quality of sleep, stress, and quality of life through a questionnaire targeting elderly stroke patients using welfare facilities for the disabled, and confirmed the correlation between variables. We also conducted a regression analysis to analyze the effects of physical activity, quality of sleep, and stress on quality of life. Results : The results of this study were as follows: First, there were significant differences in gender, education level, and economic level in comparing the general characteristics of elderly stroke patients. Second, there was a significant correlation in comparing the correlation between the quality of life of elderly stroke patients and physical activity, sleep, and mental health. Third, the physical activity, sleep, and mental health of elderly stroke patients affected the quality of life. Conclusion : For stroke patients who experience difficulties in the form of physical, mental, social, and environmental burdens, prevention is the most important, and after the onset, we should do our best to use accurate basic data to provide intervention and rehabilitation to improve the quality of life.

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 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.
