Efforts to employ smart home sensors to monitor the indoor activities of elderly single residents have been made to assess the feasibility of a safe and healthy lifestyle. However, the bathroom remains an area of blind spot. In this study, we have developed and evaluated a new edge computer device that can automatically detect water usage activities in the bathroom and record the activity log on a cloud server. Three kinds of sound as flushing, showering, and washing using wash basin generated during water usage were recorded and cut into 1-second scenes. These sound clips were then converted into a 2-dimensional image using MEL-spectrogram. Sound data augmentation techniques were adopted to obtain better learning effect from smaller number of data sets. These techniques, some of which are applied in time domain and others in frequency domain, increased the number of training data set by 30 times. A deep learning model, called CRNN, combining Convolutional Neural Network and Recurrent Neural Network was employed. The edge device was implemented using Raspberry Pi 4 and was equipped with a condenser microphone and amplifier to run the pre-trained model in real-time. The detected activities were recorded as text-based activity logs on a Firebase server. Performance was evaluated in two bathrooms for the three water usage activities, resulting in an accuracy of 96.1% and 88.2%, and F1 Score of 96.1% and 87.8%, respectively. Most of the classification errors were observed in the water sound from washing. In conclusion, this system demonstrates the potential for use in recording the activities as a lifelog of elderly single residents to a cloud server over the long-term.

Every year the number of the elderly increases in Korea thanks to the improvemen of social and economical levels and the development of medicine. However, many problems such as insufficent care and the isolation of the elderly have been commonplace. This trend exists not only because of increased lifespan but also the changing social structure of the nuclear family. Accordingly, inspite of the development of medicine, geriatric diseases including circulatory diseases are increasing in proportion of elderly population, as well as the severity. Therefore, it is important to emphasize that health care programs provide the best possible health care and functional capacities in terms of healthy elderly lifestyles. Especially, the phenomena of aging and geriatric diseases taking place with the elderly naturally are affected by lifestyle and the drastic changes in exercise patterns. This study aims to improve geriatric health by introducing a rhythmic movement program for the elderly to estabilish a health-promoting self-care system and by developing quality of life, perceived health status, their physical and physiological functions and emotional state. The theoretical framework used in this dissertation is derived from the Health-Promoting Self-Care System Model (Simmons, 1990), which integrates the Self-Care Deficit Nursing Theory (Orem, 1985), the interaction model of Client Health Behavior (Cox, 1982) and the Health Promotion Model (Pender, 1987). As a quasi-experimental design, the nonequivalent control group pretest-posttest design is utilized for this study. The subjects of this study consist of 64 people, over 65 years old who live in 2 nursing homes for the aged located in S city , Kyong-gi province and volunteered for this study from July, 12, 1999 to September, 17, 1999. They are divided into two groups：33 in the experimental group and 31 in the control group. The experimental group particpated in the Rhythmic Movement Program at the nursing home, which was comprised of 45 minutes a session, 5 sessions a week during 9 weeks. In order to measure the results of the Rhythmic Movement Program, aspects of perceived health status, balance, flexibility, grip strength, leg strength, heart rate, blood pressure, depression, anxiety and the quality of life were measured before and after participating in the Rhythimic Movement Program for the experimental group after 9 weeks, as well as the control group. The collected data were processed by SPSS PC+ and analyzed by the X2 test, t-test, ANCOVA and the Pearson Correlation Coefficient. The results of this study are as follows: 1. The perceived health status conditions in the experimental group show statistically significant improvement when compared to the control group (F=17.51, p=.000). 2. The physical and physiological functions, that is, balance (F=17.51, p=.000), flexibility (F=8.01, p=.006), grip strength (F=3.21, p=.018) and leg strength (F=25.78, p=.000) in the experimental group are higher than the control group. The vital signs, that is, the number of heart rate (F=.022, p=.884), systolic pressure (F=1.73 p=.193), and diastolic pressure (F=2.74, p=.103) in the experimental group compared to the control group decreased, but doesn't show statistically significant differences. Immune responses (F=5.13, p=.003) showed statistically significant increases in the experimental group when compared to the control group. 3. The emotional state are improved, that is, degree of depression (F=11.56, p=.001) and degree of anxiety (F=9.14, p=.004) in the experimental group showed statistically significant decreases. 4. The quality of life in the experimental group (F=3.03, p=.037) showed statistically significant differences compared to the control group. 5. The observations of the relationships among the perceived health status, emotional state , the quality of life, the relationships between the perceived health status, the degree of depression (r=-.653, p=.000) and the degree of anxiety (r=-.786, p=.000) were in contrary propotions, while the relationships between the perceived health status and the quality of life (r=.234, p=.008) were in direct propotion. In conclusion, the Rhythmic Movement Program used in this study for geriatric nursing care is simple and safe for application to the elderly and shows significant effects by implementing 5 sessions a week for 9 weeks. The Rhythmic Movement Program improves the quality of life, maintains as well as improves the physical and physiological fuctions and emotional state, therefore this program is strongly recommended for positive applications for independant geriatric nursing health care.

Purpose: Previous evaluation studies of the visiting nursing program explained an average change of the participants' health status, without considering socio-ecological characteristics and their impacts. However, these factors must affect individual health problems and lifestyles. For effective and appropriate community based programs, the Geographical Information System(GIS) can be utilized. GIS is a computer-based tool for mapping and analyzing things that happen on earth, and integrates statistical analysis with unique visualization. The purpose of this study was to evaluate visiting nursing care and to advocate the usefulness of planning and evaluating visiting nursing programs using Exploratory Spatial Data Analysis(ESDA) with GIS technology. Methods: One hundred eighty-four elderly participants with cerebrovascular risk factors who lived in 13 areas of one community received visiting nursing care. The data analyzed characteristics of pre-post change and autocorrelation by ESDA using GIS technology. Results: Visiting nursing care showed an improvement in the participants' lifestyle habits, and family management ability and stress level, while the improvements were different depending on the regions. The change of family management ability and stress level correlated with neighborhoods (Morgan's I=0.1841, 0.1675). Conclusions: Community health providers need to consider the individual participant's health status as well as socio-ecological factors. Analysis using GIS technology will contribute to the effective monitoring, evaluation and design of a visiting nursing program.

Purpose: This study was performed to measure expectations regarding aging among community-residing older adults, identify sociodemographic characteristics associated with the level of expectations regarding aging, and examine whether expectations regarding aging were associated with health-promoting behaviors. Methods: Data was collected by using questionnaires of a short version of the Expectations Regarding Aging Survey (ERA-18) and Health Promoting Lifestyle Profile II (HPLP II) from 99 older adults who resided in the community of Kyunggi, Daegu, and Kyungpook province. Results: More than 75% of the participants reported that it was an expected part of aging to have more aches and pains, to become depressed, and to become more forgetful. The mean score of expectations regarding aging was $23.15{\pm}17.80$ (possible range 0-100). The old-old, women, those with less education, less monthly allowance and poor health status had lower expectations regarding aging than other elderly. After controlling for sociodemographic characteristics and perceived health, expectations regarding aging were independently associated with health-promoting behaviors in older adults. Conclusion: The findings demonstrate that older Korean adults have low expectations regarding aging, and expectations regarding aging influence health-promoting behaviors.

A small apartment housings in Korea, which is built mass-product from 1980s, are dissatisfied, in spite of good condition, due to the growing living areas and changing lifestyle of the residents. Many of them confronted with slum areas and the kinds of housing stock accumulated much more in Korean contexts. For the existing small houses, it could be discuss an adaptation model to the increasing requirement standards of the house residents; wider living area, new facilities and a style of new residence. A social policy for elderly people who are handicap in physical and economical aspects, is home stay system rather than national support. But it is not easy to find the three generation family house in Korea context, specially apartment house. This paper deals with the vertical unification typology of two dwelling units to one, in order to supply three generation houses by remodel existing small apartment houses constructed by Korea National Housing Corporation. The use of convert houses into vertical expansion are expected to be a house of three generation family, it can also enhance privacy against conflictive activities in a house. And also the merging types of two dwelling units into one can be used as a device to get rid of the monotonous characteristics and gain diversity in the declining stock housing.

Purpose: This qualitative study aimed to understand older adults' perspectives on successful aging and develop a model of a successful aging process, within the Korean socio-cultural context. Methods: This study used a Grounded Theory approach. Through theoretical sampling, 14 participants were selected from older adults at a public health center and a volunteer institution in Gyeonggi Province, South Korea. Results: The basic social process identified was "expanding the aging self", which was preceded by three phases, namely, adjusting to the changes, developing the valuable self, and embracing the environment. Participants used 2-3 strategies for successful aging in each phase. For adjusting to the changes, participants used strategies such as "adopting a positive attitude", "accepting the changes", and "being at the center of life". To develop the valuable self, "re-identifying capacities", "having something to do", and "advancing to a healthy lifestyle" were used. Participants embraced their environments with "sharing with others" and "embracing younger generations". The causal condition for expanding the aging self was the changes in participants' physical, mental, or psychosocial situations. Conclusion: These findings suggest a theoretical foundation for the development of potential nursing interventions to promote self-care management and the interpersonal relationship for successful aging among Korean elderly individuals.

Purpose: The aim of this study was to examine the characteristics of hypertension-related nursing intervention programs and their effects on systolic and diastolic blood pressure. Methods: Fifteen studies were selected from four databases (Korean studies, Riss4U, RICHIS, and JKAN) published as of 2009. They were analyzed by meta-analysis method. The selected studies contained a control group with pre-test and post-test design, measured blood pressure as a dependent variable, and used a reported statistical value for blood pressure to measure the size of effects. Results: The hypertension-related nursing intervention programs were relatively effective in lowering both systolic and diastolic blood pressure, although they were more efficient to decrease diastolic pressure. Among the hypertension-related intervention programs, complementary and alternative therapies were more effective in lowering blood pressure compared to lifestyle change intervention. Conclusions: To acquire substantial data of intervention effects, and complementary and alternative therapy, subjects in pre-hypertensive stage, and elderly people, better industrial and scholastic research methods need to be developed for future research. Further studies are needed to establish complementary and alternative therapies. Studies with different group of participants and studies using effective research design are in need as well.

주거 공간에 건강관리에 필요한 서비스가 제공되는 것은 'aging in place'의 실현을 가속화할 것이다. 그리고 이러한 주거공간의 변화는 의료비를 절감하고 삶의 질을 향상하는 복지 측면에서도 중요하다. 본 연구에서는 고령자가 스스로 건강을 관리할 수 있도록 헬스케어 서비스(Healthcare service)를 아파트 단지 내에 적용하는 계획방안에 대해 도출하고 주거복지동의 첫 사업 대상지인 가양 7단지 영구임대주택 단지를 중심으로 내용을 전개하고자 한다. 먼저 거주자의 헬스케어 서비스 이용의향에 대해 조사하고 관심이 높은 응답자를 중심으로 실제 시범사업이 적용된 서비스의 사용모습 관찰 및 심층 인터뷰를 통해 추후 계획시 고려할 사항에 대해 도출하였다. 가양 7단지의 경우 유헬스케어 서비스에 대한 요구는 고령자보다는 고령자 진입층에서 더 강력하게 나타나지만 공통적으로 주호의 협소함으로 기기 설치 및 측정에 어려움을 느끼고 있었다. 관찰조사 결과 주호는 사용자세의 불편함으로 입식구조의 측정공간 계획이 필요하며 장비보관장소도 필요하다. 그리고 헬스케어 서비스를 위한 프로그램은 건강측정, 건강관리, 외부 시설과 연계된 시설로 나눠 계획할 수 있으며, 이는 건강측정 공간을 기본형, 즉 최소형으로 하여 점차 확대 적용할 수 있다. 가양 7단지의 경우, 별도의 복지 건물이 신축되므로 기능을 복합적으로 구성하는 혼합형의 프로그램을 적용할 수 있으며, 반자립 사용자에 대한 서비스까지 확대 적용하는 계획이 필요하다.
