The purpose of this study is to examine the effect of care workers' assistance services on behavioral changes of the elderly. To achieve this, a survey was carried out on 100 elderly people, who receive the services from care workers in J area-based elderly care facilities, and elderly patient families. The results of this study are as follows. First, the effect of care workers' assistance services on the elderly's satisfaction of physical activities showed that the nursing and caregiving services have a significant positive effect on their satisfaction of physical activities(p<.05). Second, the effect of care workers' assistance services on the elderly's satisfaction of psycho-emotional activities showed that the caregiving services have a significant positive effect on their satisfaction of psycho-emotional activities(p<.01). Third, the effect of care workers' assistance services on the elderly's satisfaction of social cognition activities showed that the caregiving services have a significant positive effect on their satisfaction of social cognition activities(p<.01). Consequently, if the elderly receive the repetitive and continuous nursing and caregiving service in the limit that is forced to deteriorate the elderly's physical, psychological and cognitive development, and slow down their activities, there will be changes and promotion in their physical, psychological and cognitive behaviors. In other words, it is of use in that care workers' continuous assistance services can improve the elderly's life, driven by the changes of their physical, psychological and cognitive behaviors.

To compare of body composition and backmusclestrength between physical activity group (PAG) and non-physical activity group (Non-PAG). From Jun 14 to July 13 2018, 66 students were divided into PAG (male 20, female 13) and Non-PAG (male 18, female 15) from questionnaires for general characteristics and activity. All participants were measured body composition (Inbody 720, Biospace, Korea) and backmusclestrength (T.K.K. 5402, TAKEI, Japan) after obtaining written informed consent. Statistical analysis was performed by independent t-test and cross-sectional test using SPSS ver. 19.0 (USA). Sex and body mass index were not significant difference between two groups. Exercise was significant difference between PAG and Non-PAG(100% vs. 45.5%, p<0.001), especially running and push-up, sit-up(p<0.001). Body composition was no significant difference between PAG and Non-PAG (p>0.05). Backmusclestrength was significantly higher in PAG than that in N on-PAG (p<0.01). It is suggested that exercise affects to Backmusclestrength.

This paper explores the how the disability type, severeness and economic activeness affects marital satisfaction, and seeks to improve marital satisfaction among disabled by clarifying mediating effects of discriminatory experiences in everyday experiences. This research was done with 3,463 married disabled who were prone to everyday discrimination, among whom were enrolled in research database of Employment Development Institute of Korea Employment Promotion Agency for the Disabled. The research showed positive effects between marital satisfaction and everyday discriminatory experience except for unemployed people and severe among all the disabled type (external disability, sensory disability, mental disability, internal disability), disability severeness (severe and light), and economic activeness (paid workers, self-employed, home-worker, unemployed, not economically active). Also, relationship between disability type, severeness, economical activeness and marital satisfaction was partly mediated through everyday discriminatory experiences. Therefore, active movements to reduce everyday discrimination are strongly advised.

This study was investigated to identify the factors influencing health related quality of life in older women with low muscle strength in Korea. The study design was a cross sectional study based on 7th Korea National Health and Nutrition Examination Survey data and the data were analyzed using the SPSS 26.0 program. The level of Health related Quality of Life(HRQoL) in older women with low muscle strength was 0.84. There were significant differences on HRQoL according to age, education level, perceived health, aerobic exercise, perceived stress, arthritis, osteoporosis and depression. The risk factors of HRQoL in older women with low muscle strength were age, education level, perceived health, perceived stress, aerobic exercise and arthritis. Based on this results to improve HRQoL, physical activity intervention should be developed to improve muscle strength and to manage arthritis in older women.

Purpose The purpose of this study was to examine the relationship between physical activities, sleep disturbance, and health related quality of life (HRQOL) in patients with chronic obstructive pulmonary disease (COPD). Methods A descriptive survey design used pretest dataset of COPD symptom management intervention study (N=245). Measures included the international physical activity questionnaire, the COPD and asthma sleep impact scale, and the St. George's respiratory questionnaire of HRQOL. The data were analyzed using descriptive analysis, t-test, ANOVA, Pearson correlation coefficients, and simultaneous multiple regression by the SPSS WIN 18.0 program. Results The mean scores (SD) of HRQOL and sleep disturbance were 36.04 (19.43) and 14.33 (6.20), respectively. About 32% of participants were physically inactive. The multivariate approach showed the patients who have more sleep disturbance (β=.27), lower levels of FEV1 % predicted (β=-.23), lower physical activities (β=-.19), lower household income (β=-.16), and diagnosed longer than 5 years (β=.14) reported lower HRQOL (R²=.34). Conclusion The findings of this study suggest that improving the quality of sleep and physical activities can be efficient strategies for HRQOL in patients with COPD. Future research in enhancing HRQOL through improving sleep quality and physical activities is needed.

This study tends to grasp the physical activity on its influences and effect s to the mental health of middle school students and we tried to look for a specific plan that will help to improve middle school students' mental health. We analyzed 36,530 students in middle school using a basic data "9th (2013) health behavior of juvenile on the online". The study is analyzed by complex sample data analysis method. The degree of euphoria recognition showed the low feeling of happiness when students exercise directly below two times rather than three times a week in the Physical Education class at school. On the other hand, the possibility of stress perception degree and suicide attempt is lowered. If the number of sports team participating is below one team, euphoria would be lowered and the limit of stress perception is high. However, the participation of one or two teams make the possibility of suicide lessens rather than students taking part in more 4 teams. In order to help middle school students reduce their stress and improve their happiness, they need to participate in sports as a regular team and join intramural games more than three times a week. In this case of the lower grade, it is considered that it is necessary for them to combine the educational program for the emotional support to control their extreme behavior.

This study was conducted to determine which factors would predict metabolic syndrome (MetS) perception and exercise by applying a machine learning classifier, or Extreme Gradient Boosting algorithm (XGBoost) from July 2014 to December 2015. Data were obtained from the Korean Community Health Survey (KCHS), representing different community-dwelling Korean adults 19 years and older, from 2009 to 2013. The dataset includes 370,430 adults. Outcomes were categorized as follows based on the perception of MetS and physical activity (PA): Stage 1 (no perception, no PA), Stage 2 (perception, no PA), and Stage 3 (perception, PA). Features common to all questionnaires for the last 5 years were selected for modeling. Overall, there were 161 features, categorical except for age and the visual analogue scale (EQ-VAS). We used the Extreme Boosting algorithm in R programming for a model to predict factors and achieved prediction accuracy in 0.735 submissions. The top 10 predictive factors in Stage 3 were: age, education level, attempt to control weight, EQ mobility, nutrition label checks, private health insurance, EQ-5D usual activities, anti-smoking advertising, EQ-VAS, education in health centers for diabetes, and dental care. In conclusion, the results showed that XGBoost can be used to identify factors influencing disease prevention and management using healthcare bigdata.
