A smart home system improves the elderly's quality of life by monitoring and analyzing their movements and health conditions with better health-care and social support services. Therefore, there has been an effort to adopt a smart home system for the independently living elderly. However, to the best of our knowledge, no study has investigated the usability of a smart home system on actual independently living elderly housing in long-term settings. Thus, this study aims to demonstrate the usability of a smart home system on independently living elders in living lab conditions. The BLE smart band and the BLE receiver were chosen for the smart home system to monitor the movement of the participants in their homes as well as to monitor the heart rates, step counts, sleep index. Nine independent living elderly from the senior welfare center in Kimjae participated in this living lab demonstration experiment for ten months. This demonstration experiment confirmed the effectiveness of low-cost and easily adoptable IoT-based BLE sensor sets on independent living elders and discussed the troubles and limitations of the experiment. By grasping the pros and cons of IoT-based BLE sensor sets, this study seeks to improve the accessibility and usability of smart home systems for the elderly population in independent living arrangements.

Purpose: This descriptive study investigated the mediating and moderating effects of fear of fall on the relationships between health belief on fall, fall-related knowledge and fall prevention behaviors among older adults Methods: We enrolled 229 older adults residing in a senior citizen hall and community welfare center, and investigated their health belief on fall, fall-related knowledge, fall prevention behavior, and fear of fall. Descriptive statistics, ANOVA and t-test were used to analyze differences in variables. Pearson correlation and multiple regression were used to investigate mediating and moderating effects of the fear of fall on the relationships between health belief on fall, fall-related knowledge, and fall prevention behaviors. Results: The fear of fall significantly mediated the health belief on fall and fall prevention behaviors, but there was no significant mediation between knowledge of fall and fall prevention behaviors. The fear of fall did not have a moderating effect on the relationships between health belief on fall, knowledge of fall, and fall prevention behaviors. Conclusion: It is important to investigate and implement health belief on fall and fear of fall among older adults to improve their fall prevention behaviors.

This study aim to evaluate dietary quality and nutritional status according to the consumption of health functional food using Nutrition Quotient for Korean elderly (NQ-E) for 288 elderly people attending senior welfare centers in Gyeonggi-do. The questionnaire consisted of items about general information, health functional food, and Nutrition Quotient for Korean elderly (NQ-E). Chi-squared test, Fisher's exact tests, and Analysis of Covariance (ANCOVA) were performed using the SAS program ver. 9.4. Among the male and female subjects, the female subjects consumed more health functional food. The results of the dietary quality and nutritional status difference according to the intake of health functional food showed significant differences only in the areas of variety and abstinence among nutrition quotient factors for men, while no significant differences were observed in any of the nutrition quotient factors for women. In conclusion, focused-nutrition education program and useful guideline is needed for promoting adequate consumption of health functional foods in elderly.

Purpose: The number of people with disabilities and the elderly over 65 years of age is gradually increasing due to physical disabilities and social aging. Their typical physical disorders or chronic diseases include low back pain, sciatic pain, arthritis, and musculoskeletal systems such as discs. The average prevalence of disease is 78%. These are various physical obstacles and hindrances in daily life. Research design, data and methodology: From August 6, 2019 to September 24, 2019, the Senior Welfare Center in Gyeyang-gu, Incheon, operated a healthy body exercise and health education program for living health management. Results: The vascular health index using U-Bio pulse wave was relatively good at the first average of +7.4, but the second average of -6.3. This can be seen as a result of the combination of diet and lifestyle education along with the effect of corrective exercise. As a result of body shape measurement analysis, the number of persons requiring management with 3 or more body imbalances was found to be from 75% before to 62.5% afterwards. Conclusions: Exercise effect appears when exercise lasts for at least 10 weeks. Some performances were good, but there were limitations due to the operation of a short training period.

This study proposed a multiple regression equation for predicting VO2max of elderly men and women using functional performance variables required to conduct daily activities. The subjects of this study were 58 elderly men (72.4±5.9 yrs) and 117 elderly women (73.4±4.5 yrs) aged 65-90 who belong to the senior welfare center. The maximal graded exercise test using a cycle ergometer and functional performance representing muscle strength, endurance, static and dynamic flexibility, mobility, and agility were measured. For statistical processing, multiple regression analysis was performed, and the statistical significance level was α = .05. As a result, the VO2max estimation formula for the elderly was 0.419 (standing up and sitting down a chair) + 0.199 (leg endurance against wall) + 5.383, and R2=0.406. In addition, the VO2max estimation formula for elderly women is - 0.737 (standing up from a supine position) - 0.144 (waking around two cones in a figure 8) - 0.135 (%body fat) + 0.042 (one leg balance with eyes open) + 29.395, R2=0.367 was calculated. The conclusion is that if the maximal graded exercise test is not available, it is considered that VO2max of the elderly can be predicted properly by using the estimation formula calculated based on the functional performance variable.

This study examines the impact of Long-Term Care Insurance(LTCI) on family caregivers(especially focused on female household members) labor supply in South Korea. When public care and informal care are substitutes, LTCI will change allocation of time of family caregivers to spend more time to paid work. The impact of LTCI on labor supply depends on each country's institutional level of public care services. If public care can not substitute for informal care, labor supply of family caregivers will not rise significantly. The conclusions of vigorous empirical study from western countries' are incompatible and problem of endogeneity in terms of methodology has been raised consistently. The dataset of this study are used the third and ninth waves of Korea Welfare Panel. As a result, the introduction of LTCI had no effect on labor supply of household members. Robust findings suggest the positive effects of caregiving on labor market outcomes in simple comparison t-test, but not in fixed-effect regression. Compared with western countries, South Korea's public care services can be interpreted as a supplement to only part that remained at the level does not substitute informal care. These findings may suggest that if LTCI become much more prevalent in the future, senior citizens and family members will be able to choose the LTCI arrangement that best suits their needs.

This study examined the role of social support and mastery in the effects of hopelessness and depression on suicidal ideation in order to identify elders' suicide and it's related factors. Especially, it focused to find out whether the hopelessness excluding depression has an independent effect on elders' suicidal ideation, and psychosocial factors such as social support and mastery has an interaction effects with elders' hopelessness variables and depression on suicidal ideation. This study recruited 297 elders over 65(older persons in the elder education programs of senior welfare center in Masan, Changwon and Jinhae) and employed a self-administered survey method during January, 2007. The following are the major results of the study. First, the level of hopelessness, depression and suicidal ideation related elders' suicide indicated differences according to their educational level, marital state, income, and their chronical disease numbers. Especially, the lower income and higher chronical disease numbers showed higher level of hopelessness, depression and suicidal ideation among the elder subjects. Second, interaction effects of social support and depression were significant in suicidal ideation, the more level of social support in elder' subjects, the lower the suicidal ideation. While, interaction effects of social support and hopelessness, and mastery and depression/hopelessness in suicidal ideation were not statistically significant. Third, psychosocial factors such as social support and mastery on elders' suicidal ideation have a significant effect when other relevant variables are controlled. From these results, hopelessness is other significant factor predicting suicidal ideation(suicide) among elders. Also, social support and mastery is very significant factor influencing to prevent or decrease suicidal ideation among elders.
