The number of elderly people with dementia is increasing as fast as the proportion of older people due to aging, which creates a social and economic burden. In particular, dementia care costs, including indirect costs such as increased care costs due to lost caregiver hours and caregivers, have grown exponentially over the years. In order to reduce these costs, it is urgent to introduce a management system to care for dementia patients. Therefore, this study proposes a sensor-based abnormal behavior detection system to manage dementia patients who live alone or in an environment where they cannot always take care of dementia patients. Existing studies were merely evaluating behavior or evaluating normal behavior, and there were studies that perceived behavior by processing images, not data from sensors. In this study, we recognized the limitation of real data collection and used both the auto-encoder, the unsupervised learning model, and the LSTM, the supervised learning model. Autoencoder, an unsupervised learning model, trained normal behavioral data to learn patterns for normal behavior, and LSTM further refined classification by learning behaviors that could be perceived by sensors. The test results show that each model has about 96% and 98% accuracy and is designed to pass the LSTM model when the autoencoder outlier has more than 3%. The system is expected to effectively manage the elderly and dementia patients who live alone and reduce the cost of caring.

Living conditions of the rural elderly were assessed in terms of clothing behavior, health and nutritional status, housing and envioronmental condition, and psychological adjustment. The subjects were eighty individuals over sixty residing in the rural community of Iksan-kun, Chollabukdo. The interview method using questionnaires, direct measurement, and observation was used for this study. Data were compared with those obtained from a previous study of the elderly residing in an urban area. Clothing behavior showed that the elderly residing in the rural community were more concerned about plain and conservative design of clothes than their urban counterparts. Special protective clothes for cropdusting with agricultural chemicals had not been prepared. The following urgent needs were pointed out: development and supply of agricultural chemical protective clothing and development and education of appropriate washing and clothing care methods. The health status of the elderly was generally good, but poor eating habits were found more frequently in the rural elderly than among the urban dwellers. Several dietary nutrient intakes were insufficient. Contrasting the urban elderly with the rural group, it was found that the urban group lacked sufficient vitamin A and vitamin C and the urban women had insufficient calorie whereas the rural group was deficient in protein, vitamin A, calorie, and fat. A significant relationship was found between dietary nutrient intake and health index, food habit points, self recognized health status, meal satisfaction, and economic status. Urgent needs of the development of a nutrition education program for the elderly were pointed out. Most of elderly residing in the surveyed rural communities were living alone or with their spouse only, therefore only one room was used among the three or four available rooms. Most of the rural elderly were living either in a traditional Korean house built with differing floor levels or in a modified Korean style house. Minimal modernization had been made for kitchen facilities such as sink and gas range or for heating facilities with the briquette boiler. However, sanitary space such as lavatory and bathroom had not been remodeled. A housing welfare program for rural communities should be implemented at the national level. The comparison of psychological characteristics of the rural elderly with their city counterparts revealed that the rural elderly have a more stable psychological status and optimistic attitude than those living in a city. However, it was found that most of the elderly did not have any future plan. Community programs for the elderly including hobbies or leisure activities or education programs to generate close interpersonal relationships with their children should be developed and provided.

This study was conducted to identify the effects of a comprehensive health care program for elderly living alone on blood pressure, fasting glucose, body composition, and depression at a senior welfare center in M city. The study employed a one-group, pre-posttest design. The comprehensive health care program lasted for three months, from March to June in 2015, and consisted of open health education, exercise class, health consulting and personal education, nutritional consultation, and a self-support group. The sample elements of this study were individuals over 65-years-old with hypertension or diabetes mellitus, living near a welfare center in M city. A total of 34 participants were initially selected, but five subjects who were attended less than five times were excluded; therefore, a total of 29 individuals were included. The t-test and Pearson's correlation were used to analyze the data. The characteristics of subjects were 19 male(65.52%) and 10 female(34.48%). The most common age was 70 (16 subjects;55.17%). Additionally, 14 subjects were suffering from hypertension and diabetes mellitus (48.27%), which were occupied in the largest number in this study. The average attendance number of health programs was 10.28 times(${\pm}4.17$). In this study of subjects were significantly lower systolic blood pressure(t=3.275, p=0.004), body weight(t=3.878, p=0.001), depression(t=3.308, p=0.004) compared to pre-test. As the elderly population has increased, the number of individuals living alone has also increased. Accordingly, then need for physical and psycho-social health programs targeting the elderly is greater.

This study examined the prevalence of and factors associated with unmet care need among community-dwelling middle-aged and older people in Korea. Data were from the 2006 Korean Longitudinal Study on Ageing (KLoSA), a national survey of 10,254 non-institutionalized adults aged 45 or older. Having unmet care needs was defined as needing personal assistance with activities of daily living (ADL) or instrumental activities of daily living (IADL) but having no available helper. Weighted logistic regressions were fitted to examine factors associated with unmet care needs. Overall, 7.3%, 14.5%, and 41.8% of subjects among the middle-aged, younger old, and older old, respectively, reported care needs of these, 34%, 33%,and 24% had unmet needs. Factors associated with unmet needs differed among the three groups: Education and income level were negatively associated with unmet needs among the middle-aged, but living alone was the only factor positively associated with unmet needs in both the younger and older old. The prevalence of and factors associated with unmet care needs differ by life-stage. Needed are home- and community-based care and services to meet the need for personal assistance among the elderly living alone in a community.
