Objectives: Frailty and sarcopenia are recent important concepts in elder health care. Sarcopenia is the most important factor influencing frailty, and exercise and nutritional status are known to affect sarcopenia. The purpose of this study was to identify the relationship between nutritional status, sarcopenia, and frailty. Methods: This study was a cross-sectional design. The subjects of this study were 411 elderly people aged 65 or older from 10 villages in Gyeongnam. The survey tools were the K-FRAIL for frailty, the GDS-SF for depression, the SARC-F questionnaire for sarcopenia, and the DETERMINE for nutritional status. Frequency analysis, the chi-square test, and multiple logistic regression analysis were performed using the SPSS 25.0 program. Results: As a result of the chi-square test, there was a significant difference in the nutritional status and the frailty proportion (p<0.001), and there was a significant difference between frailty and suspected sarcopenia (p<0.001). After adjustment, nutritional status was significantly associated with sarcopenia (OR=2.946, p<0.001). In addition, nutritional status was significantly associated with frailty (OR=2.958, p<0.001), and sarcopenia also had a significant effect on frailty (OR=5.898, p<0.001). Finally, even after including sarcopenia, nutritional status had a significant effect on frailty (OR=2.246, p=0.002). Conclusions: Nutritional status can have both a direct effect on frailty and an indirect effect through sarcopenia, and it was found that sarcopenia also affects frailty. Therefore, it is necessary to evaluate sarcopenia and nutritional status and to evaluate their levels in the elderly and to take appropriate interventions.

The purpose of the present study was to develop a community-based intensive health care program for the community dwelling elderly to strength their functional status and to verify the effect on their geriatric syndrome. A one-group pretest-posttest design was used for the study. A total of 69 frail elderly, who lived in the area within 20 minutes by car, were committed themselves to the day care center(Sangikjae), and had the ability of verbal communication were selected from G city in Kyunggi province. The participants completed a set of questionnaires to measure the sub-score of frailty, fall, urinary incontinence, malnutrition, and mild cognitive disorder domain, using the Otasha-Kensin through the physical examinations and interviews. After 4 weeks of intervention, the outcome was measured to evaluate the effects of the program, and the data obtained were analyzed using descriptive statistics, paired t-test and McNemar test. The results showed that the sub-score of frailty, fall, urinary incontinence, and malnutrition domain were statistically significantly decreased after intervention except those of urinary incontinence and mild cognitive disorder domain, implying that the risk of frailty, fall, and malnutrition was decreased. These findings indicated that community-based the intensive health care program is effective for relieving geriatric syndrome of the community dwelling elderly.

If frail elderly could use home care services adequately, quality of their life might improve and their costs of service would be decreased. The purpose of this study is to examine the factors on institutionalization of elderly using home care services in Korean long-term care insurance system. This study used the data of '2009 satisfaction survey of Korean long-term care system'. The survey proceeded using sampling data by region, level of long-term care need, and insurance type among beneficiaries from August 2009 to September 2010. The onset dates of institutionalization of 1,230 participants were ascertained from long-term care insurance claim data. This study calculated hazard ratio through Cox Proportional Hazard Model. The results showed that if elderly using home care services suffer a fracture, the hazard ratio of institutionalization is higher significantly. Although not significant, if older persons have more items of damaged cognitive functions, the hazard ratio of institutionalization is higher. The results have policy implications to supplement of home care service system and postpone institutionalization of elderly.

The purpose of this study was to describe the overall physical environment's features of nursing homes for Korean American elders in the United States. This investigation was conducted in Korean American nursing homes on the East Coast and in the Midwest with multiple qualitative data collection methods, such as interviews, observations, document review, and field notes. The findings of this study are as follows: 1) Although almost all respondents were unable to speak and understand English at all, most written materials in nursing homes were in only English; 2) The nursing homes were placed near or within the Korean communities; thus, it contributed to close ties with religious Korean American groups and other groups in the ethnic communities; 3) Whether the facility's physical features looked like those of a hospital or a home, many residents did not consider a nursing homes as a real home; 4) A fenced garden in the nursing home in the Midwest was the residents' favorite public space; 5) Due to being forced to room with residents who had dementia and were bedridden, they were more likely to have conflicts with their roommates and feel uncomfortable living in their room; and 6) The facilities seemed to be designed without consideration to protect residents' privacy.

Purpose: Behavioral symptoms in dementia (BSD) are one of the most disturbing behaviors to caregivers and a major reason for nursing home placement. Behavioral symptoms are often treated with psychotropic drugs (PD), however, the effect of such drugs for the frail elderly dementia patient is not certain because of their critical adverse effects. Theoretical model applicable to nursing practice for BSD in nursing homes, which is essential in guiding and evaluating such interventions, is absent. This article presents the process of developing a theoretical model of BSD in nursing homes. Method: Using Walker and Avants' theory synthesis method, three behavior models and two system models were incorporated into the proposed model to provide the theoretical and analytical explanation of the relationships between PD usage, its determinants, and BSD. Results: Resident variables and nursing home variables related to the two focal concepts (i.e., PD usage and BSD) were identified. Resident variables include demographical characteristics such as age and gender, and dementia-compromised functions such as cognitive and functional impairment. Nursing home variables include facility characteristics such as ownership type and size, and physical and psychosocial environment. Conclusion: The proposed model suggests that fulfillment of resident unmet needs through improvement of physical and psychosocial environment may produce better health outcomes of nursing home residents with BSD. Assessment and intervening environmental triggers of such behaviors are also suggested to be prior to the PD usage.

Purpose: To develop and test the validity and reliability of the Korean version of outcome expectations-2 for exercise. Methods: The Korean version of outcome expectations for exercise-2 was developed through forward-backward translation techniques. Content, criterion, and construct validity using confirmatory factor analysis and an internal consistency reliability were conducted. Survey data were collected from 200 older adults living in a community. Results: The Korean version of outcome expectations for exercise-2 had factor loadings of the 13 items ranged from .20 to .76, and was validated by confirmatory factor analysis (CFI=.829, NFI=.754, RMSEA=.086). Also there was a reliable internal consistency with a Cronbach's ${\alpha}$ for the positive domain of outcome expectations for exercise scale-2 of .73. Negative domain, however, reported slightly low Cronbach's ${\alpha}$ of .63. Conclusion: The findings of this study demonstrated that the Korean version of outcome expectations for exercise-2 had satisfactory validity to measure expectations regarding exercise among older adults in Korea. Negative domain, however, should be retested to verify reliability for the further study.

Purpose: The aim of this study is to identify core keyword of frailty research in the past 35 years to understand the structure of knowledge of frailty. Methods: 10,367 frailty articles published between 1981 and April 2016 were retrieved from Web of Science. Keywords from these articles were extracted using Bibexcel and social network analysis was conducted with the occurrence network using NetMiner program. Results: The top five keywords with a high frequency of occurrence include 'disability', 'nursing home', 'sarcopenia', 'exercise', and 'dementia'. Keywords were classified by subheadings of MeSH and the majority of them were included under the healthcare and physical dimensions. The degree centralities of the keywords were arranged in the order of 'long term care' (0.55), 'gait' (0.42), 'physical activity' (0.42), 'quality of life' (0.42), and 'physical performance' (0.38). The betweenness centralities of the keywords were listed in the order of depression' (0.32), 'quality of life' (0.28), 'home care' (0.28), 'geriatric assessment' (0.28), and 'fall' (0.27). The cluster analysis shows that the frailty research field is divided into seven clusters: aging, sarcopenia, inflammation, mortality, frailty index, older people, and physical activity. Conclusion: After reviewing previous research in the 35 years, it has been found that only physical frailty and frailty related to medicine have been emphasized. Further research in psychological, cognitive, social, and environmental frailty is needed to understand frailty in a multifaceted and integrative manner.

The topic of this paper is the recognition of human activities using egocentric vision, particularly captured by body-worn cameras, which could be helpful for video surveillance, automatic search and video indexing. This being the case, it could also be helpful in assistance to elderly and frail persons for revolutionizing and improving their lives. The process throws up the task of human activities recognition remaining problematic, because of the important variations, where it is realized through the use of an external device, similar to a robot, as a personal assistant. The inferred information is used both online to assist the person, and offline to support the personal assistant. With our proposed method being robust against the various factors of variability problem in action executions, the major purpose of this paper is to perform an efficient and simple recognition method from egocentric camera data only using convolutional neural network and deep learning. In terms of accuracy improvement, simulation results outperform the current state of the art by a significant margin of 61% when using egocentric camera data only, more than 44% when using egocentric camera and several stationary cameras data and more than 12% when using both inertial measurement unit (IMU) and egocentric camera data.

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.

There can be little dissension that the ultimate goal of all physical therapy interventions with the elderly is to restore or maintain the highest level of function possible for the individual. Whenever physical therapists take on this challenge, they assist elders in maintaining their identities as competent adults. Advancing age is associated with profound changes in body composition, including increased fat mass, decreased fat-free mass(particularly muscle), decreased total body water and decreased bone density. Along with these changes in body compositions, and perhaps as a direct result of them, elderly people have lower energy needs, reduced strength and functional capacity and a greatly increased risk for such diseases as noninsulin-dependent diabetes mellitus and osteoporosis. Resistance training is considered a promising intervention for reversing the loss of muscle function and the deterioration of muscle structure that is associated with advanced age. This reversal is thought to result in improvements in functional abilities and health status in the elderly by increasing muscle mass, strength and power and by increasing bone mineral density. In the past couple of decades, many studies have examined the effects of Resistance training on risk factors for age-related diseases or disabilities. We have explored the positive and negative aspects of older adults' participation in resistance training programs. The benefits to older adults are reported to be increased strength, endurance, muscle capacity, and flexibility; more energy; and improved self-image and confidence. The negative aspects include some pain or stiffness and other nonspecific problems. The positive and negative aspects of resistance training are therefore very similar to those in younger populations. Scientific investigations over the past 10 years have demonstrated that resistance training can be safely and successfully implemented in older populations. Even the frail and very sick elderly can benefit and improve their quality of life. Proper design and progression of a resistance training program for older adults is vital to optimal benefits from resistance exercise. The results of data provided by this research on resistance training for health shows that there is enough existing evidence to conclude that resistance training, particularly when incorporated into a comprehensive fitness program, can offer substantial health benefits which can be obtained by persons of all ages. These benefits, including improvements in functional capacity, translate into an improved quality of life.
