Wearable ECG monitoring is regarded as one of the most essential part in the ubiquitous healthcare environment and subsequently day-life monitoring of a heart condition has been pursued especially for the elder people. However, there are many problems to accomplish this task such as; i) implementation of long-term monitoring device, ii) development of non-irritating electrode on skin and iii) stable signal acquisition. With these aims, we have focused on implementing a non-irritating electrode with an endurable monitoring device for day-life. To accomplish our tasks, we basically developed four different types of textile electrodes that are adapted by both shape and the composed material; flat or convex shape and Ag-conductive paste material or not. It turns out to be that a convex shape and Ag-paste textile electrode has the best performance in terms of both signal-to-noise ratio (SNR) and Impedance/Phase characteristics. Furthermore, ECG amplifier (35 ${\times}$ 35 mm) has developed to resolve the ECG signal and transfer the signal to desktop computing device or portable one by RF serial communication.

Purpose: The purpose of this study was to identify family resiliency, ADL in elders with dementia, and symptom for families with an elder with dementia. Method: The participants were 102 people who were caregivers to elders with dementia and who visited the out-patient department at S. hospital for follow up care. Data were collected from August to October 2003 using a questionnaire. The collected data were analyzed using descriptive statistics and t-test aided by the SPSS/PC. Result: Family resiliency for the whole sample was within normal limits but when the sample was quarter-divided by good and poor family resiliency, based on established cut-off scores, there were differences for some characteristics according to good/poor family resiliency. These differences were for perceived health state of caregivers (t=-2.78, p=.008), economic state of family (t=-3.34, p=.002), and ADL (t=-2.56, p=.014). Conclusion: Future research should focus on the way in which family resiliency can be enhanced and on the effects of interventions for those caregivers who report poor family resiliency.

Purpose: The purpose of the study was to analyze the ADL, IADL and cognitive function of low-income elderly who are receiving the visiting nurse service in the community. Method: Study participant were 2,413 community-dwelling elderly who live in S City. The data were collected from 5th Jan. to 28th Feb. 2006. The cross-sectional descriptive survey was done using a structured questionnaire through interviews by visiting nurses. Result: The average scores of ADL and IADL was respectively high, which indicates a relatively independent everyday life. However, the score of cognitive function was 21.87(normal range is over 23). There was a significantly positive correlation among ADL, IADL and cognitive function with the pearson correlation coefficients. Conclusion: It is concluded that elder subjects who are women, old aged, and live alone should be watched carefully for the cognitive impairment. In addition, the government should apply early detection and management system for cognitive impaired people who live in the community.

This is a basic study to investigate possibility to application of cohousing model into Korea. Purpose of this study is to grasp respondents' housing value, and its influence on intention to live in cohousing. Research method used for this study was a social survey. Respondents were 214 married people residing in Seoul and its outskirts by accidential sampling. The collected data were analyzed by SPSS 12.0 program using frequency, mean, average, factor analysis, t-test, one-way ANOVA, Duncan's multiple range test, multiple regression and legit analysis. Result of this study was as follows. Housing values were classified into three categories named as individualism oriented housing value, tradition oriented housing value, and economy oriented housing value. Housing values were different by respondents groups. For example, individualism oriented housing value showed difference according to age and housing area. Tradition oriented housing value showed difference according to sex, occupation, and period of residence, while economy oriented housing value showed difference according to housing type, and home ownership. In detail, men than women, single-income family than double-income family, and detached house resident than flat resident had higher tradition oriented housing value. The younger than the elder, and Seoul resident than outskirts resident had higher economy oriented housing value. Also home owner than tenant, and the higher tradition oriented group had stronger intention to live in cohousing than others.

Background: With the increasing elderly population, the need for gait analysis of these elderly individuals is also increasing. Most devices are costly and not portable; however, smartphones using built-in sensors capable of measuring motion and are easily available. Objectives: To examine the reliability and validity of knee joint angles of the elderly using smartphone measurements during walking. Design: Quasi-experimental research. Methods: Sixteen elderly people, aged 65+ and living in Daejeon and Chungbuk, South Korea, participated in the study. Electrogoniometers and smartphones were attached to the thigh and the side and front of the shank of each subject, respectively, using double-sided tape, an arm band, and an elastic band. Each subject completed two sets of at least seven gait cycles (14 steps). Results: Both the smartphones and electrogoniometers exhibited high agreement in terms of their primary and secondary measurements (ICC>.75). The agreement between the smartphones and electrogoniometers was also high in terms of both the primary and secondary measurements (ICC<.60). Conclusion: These results indicate that smartphones can be costly equipment cannot, even though they cannot completely replace existing clinical-grade devices. Their utility is emphasized herein for measuring knee joint angles of the elderly during walking.

This paper conducted a feasibility study by applying an Internet of Things and Artificial intelligence-based management system for the elderly living alone in an aging society. The number of single-person families over the age of 50 is expected to increase, and problems such as health, safety, and loneliness may occur due to aging. Therefore, by establishing an IoT-based care system for the elderly living alone, a stable service was developed through securing a rapid response system for the elderly living alone and automatically reporting 119. The participants of the demonstration test were subjects under the jurisdiction of the "Seongnam Senior Complex," and the data collection rate between the IoT sensor and the emergency safety gateway was high. During the demonstration period, as a result of evaluating the satisfaction of the IoT-based care system for the elderly living alone, 90 points were achieved. We are currently in the COVID-19 situation. Therefore, the number of elderly living alone is continuously increasing, and the number of people who cannot benefit from care services will continue to occur. Also, even if the COVID-19 situation is over, the epidemic will happen again. So the care system is essential. The elderly care system developed in this way will provide safety management services based on artificial intelligence-based activity pattern analysis, improving the quality of in-house safety services.

Since 1980's, Countless schools across the nation, particularly in rural areas, have been closed down by the large fall in number of students. Otherwise, an elderly population has been increasing rapidly, so the demand for welfare services for the elderly population is also increasing. However, the supply of elderly welfare facilities remains inadequate. The purpose of this study is to propose remodelling plan of elderly welfare facility using Closed schools. The result of this study were as follows; in unit-based facility plans, Single room type can be used for elder who lives alone or an elderly couple. Senior Congregate Housing type can be used for four to five people. These two types have equal sunlight and ventilation conditions for each room, and are for an old man in relatively good health. Membership resort type is for the healthy senior who lives in the rural area or lives in the city who wants short-term residence. In case of a Nursing home type, the existing one-sided corridor was converted into a central corridor and each classroom is divided into four rooms. This type has advantage for nursing and management, on the other hand, the corridor is narrow and each room has differences for sunlight and ventilation.

Advances in information and communication technology have introduced self-service technologies (SSTs) to service companies, changing the way they serve. In addition, as SSTs are expanding for low cost and high efficiency, opportunities for technology to interact with consumers have increased. Restaurant managers have the advantage of the SSTs win-win strategy, which allows consumers to freely receive the products or services they want, but some consumers have low satisfaction of the SSTs, especially elder people and the blind. This study examines the effect of unmanned order payment technology on service quality evaluation. For this, we interviewed a total of 12 consumers in their 10s to 50s with the experiences of using unmanned order payment technology, applying the Grounded Theory Method(GTM). Through a review of the research participant interview materials, totally 84 concepts were derived and the concepts were analyzed to derive 15 subcategories and 10 upper categories. Finally, a paradigm model of the effect of unmanned order payment technology on service quality assessment was derived. It also found the importance of consumers' sense of obligation to use unmanned order payment technology, recognition of advantages (e.g., time savings), recognition of shadow labor, and recognition of whether the technology usage process is in the service quality assessment stage.
