  • This paper Various services exist to detect and monitor abnormal event. However, most services focus on fires and gas leaks. so It is impossible to prevent and respond to emergency situations for the elderly and severely disabled people living alone. In this study, AI model is designed and compared to detect abnormal event of heart rate signal which is considered to be the most important among various bio signals. Specifically, electrocardiogram (ECG) data is collected using Physionet's MIT-BIH Arrhythmia Database, an open medical data. The collected data is transformed in different ways. We then compare the trained AI model with the modified and ECG data.

  • The aging society increases emergency situations of the elderly living alone and a variety of social crimes. In order to prevent them, techniques to detect emergency situations through voice are actively researched. This study proposes CutPaste-based anomaly detection model using multi-scale feature extraction in time series streaming data. In the proposed method, an audio file is converted into a spectrogram. In this way, it is possible to use an algorithm for image data, such as CNN. After that, mutli-scale feature extraction is applied. Three images drawn from Adaptive Pooling layer that has different-sized kernels are merged. In consideration of various types of anomaly, including point anomaly, contextual anomaly, and collective anomaly, the limitations of a conventional anomaly model are improved. Finally, CutPaste-based anomaly detection is conducted. Since the model is trained through self-supervised learning, it is possible to detect a diversity of emergency situations as anomaly without labeling. Therefore, the proposed model overcomes the limitations of a conventional model that classifies only labelled emergency situations. Also, the proposed model is evaluated to have better performance than a conventional anomaly detection model.

  • 최근 지속적인 출산율의 감소와 평균수명의 증가로 인하여, 대한민국의 초고령 사회는 예상보다 훨씬 빠르게 증가하고 있다. 핵가족 형태가 보편화되며 1인 가구도 함께 늘고 있어서 홀로 사는 노인의 수 역시 증가하는 추세이다. 주거 공간에서 낙상사고와 같은 고령화 안전사고가 많이 발생하고 있다. 혼자 사는 독거노인들의 경우 사고 발생 즉시 대처가 가능한 보호자가 없다는 문제점이 있다. 본 논문에서는 MediaPipe를 이용한 낙상사고 감지 시스템을 개발한다. 먼저, 이 시스템은 MediaPipe를 이용해서 카메라를 통해 실시간으로 수신된 영상에서 사람을 인식하고, 자세 유형 분석을 통해 낙상사고 발생 여부를 판별하여 애플리케이션을 통해 보호자에게 현장 상황을 알려주는 시스템이다. 낙상사고가 발생했다면 보호자용 애플리케이션을 통해 사고 발생 알림 및 현장 사진을 보여준다. 이와 같은 기술을 활용하여 응급상황에 처한 노인을 빠르게 구조하며 독거노인의 생활안전사고 문제를 해결하는 데에 기여하고자 한다.

  • 고령화가 가속되면서 독거노인의 사회적 고립으로 인해 신체, 정신적 어려움이 발생하고 고독사하는 노인들의 수가 증가해 사회적 문제가 되고 있다. 또한 독거노인 관리를 위한 정부 인력은 한정되어 한 명이 담당해야 하는 사람의 수가 너무 많아 수많은 독거노인의 안전과 복지를 보장하는 데 현실적인 어려움이 있다. 이에 따라 본 논문에서는 독거노인의 안전과 복지를 책임지기 위해 IoT와 각종 센서를 활용하여 생체 정보를 수집하는 웨어러블 기기를 제작하고 데이터베이스 서버를 활용한 IT 인프라 구축을 통해 적은 인력으로 효율적인 의료 지원을 목표로 한다. 본 논문은 독거노인의 거주 환경에서 생체 데이터를 수집하고 이를 효과적으로 분석하여 컴퓨터를 통해 실시간으로 모니터링이 가능하다. 이는 고독사 상황을 사전에 감지할 뿐만 아니라 노인들의 일상생활에서 발생할 수 있는 위험 상황에 즉각적인 대처를 통해 독거노인의 안전 및 복지 수준 향상에 기여하고 나아가 소외 계층의 의료 환경 개선에 도움이 될 것으로 예측된다.

  • The aim of this paper is to find out different preference of common spaces and shared activities in senior cohousing community between regions in Korea: Seoul and other cities. Social survey was conducted nationwide and the respondents were 50s only, since they are the generation who will face to elderly housing subject within 10 years in turbulent Korean society. Collected data, about 1000, were analyzed by SPSS program using frequency, percentage, and Chi-square test. In summary, respondents mostly would like to move to senior cohousing on circumstance when they remain alone without big difference between regions. Loneliness and housekeeping were considered as the most difficult issues for the elderly to manage by themselves. Among common spaces, exercise room was the most preferred space to meeting room and kitchen. Exercise room was more preferred in Seoul than in other cities, on the contrary meeting room was evidently less preferred in other cities than in Seoul. Regarding shared activities, resident meeting, gardening, and common meal were revealed as less preferred activities than hobby exercise and tea meeting. As a conclusion, I would like to propose that a big common living room is better to be designed for meeting room cum dining and gathering room with flexibility in order to give residents chances to know each other more often. And since common space and shared activity show different preferences by regions, those are to be designed and planned reflecting region's different circumstance.

  • Ubiquitous is a Latin-derived word meaning "to exist at any time and place" like water or air. In computing, the word "ubiquitous" indicates an environment in which users have access to networks without any limitation regarding computer networks or places. Important issues in building Ubiquitous Korea (U-Korea) are the social problems appearing with a rapid increase in the old age population. Nowadays, with the rise of the nuclear family, the increase in the number of elderly people living alone, and the change in the status of women, both wives and husbands are employed outside the home, and the relatives who would be responsible for supporting the elderly sometimes are on long or short business trips, and it happens that old people can't be looked after. Therefore the government developed a wireless paging system for the sick, disabled, old and weak so that when an emergency happens, by just simply dialing 119, an emergency aid center could take prompt action. However, the present wireless paging systems composing the under-layer of the emergency aid information system have some problems, such as, a lack of reliability, problems among terminals, mobile transmitters and receiving terminals, the users' refusal to admit the need for the system and poor operational skills, administrators' perfunctory management and checks, etc. On account of these problems, the system efficiency has degraded and therefore a system upgrade is necessary. In this paper, we attempt to evaluate the newly implemented SAFE119 system, a new wireless paging system seeking to correct the problems of the current system.

  • Background: The purpose of this study is to examine the characteristics of and factors associated with long-term care (LTC) utilization under public long-term care insurance (LTCI) among end-of-life older adults in Korea. Methods: Using a 5% sample of older people aged 65 or older and their health and LTC insurance data, two-part model analyses were conducted. We compared LTC uses and their determinants during the last year of life among decedents in the year 2010 with those of survivors. We also compared the medical uses of the same sample with their LTC uses. Results: The end-of-life elderly were more likely to use LTC, and their expenditure on LTC was higher than their counterparts. Whether or not older people used LTC during their last year of life was significantly affected by age, sex, health insurance, household income, and living alone; however, LTC costs of the decedents were only affected by functional status, which may have been due to the reimbursement scheme of the current LTCI, which is mainly based on functional dependency level. For the survivors, having chronic diseases significantly increased the likelihood of LTC use, which was not the case for the decedents. End-of-life elderly with relatively low social economic status were more likely to use the LTC other than medical services, while the health conditions affected their medical uses most significantly. Conclusion: The study findings provide key information for predicting demand related to the increasing LTC needs of Korean older people at the end of life.

  • Purpose: The purpose of this study was to examine the association between oral health impact profile, depression and quality of life among community-dwelling elderly persons in South Korea. Methods: The design of this research was cross-sectional descriptive study. The participants were 266 community-dwelling individuals aged 65 and older. Data were collected from November 20 to December 20, 2011. The measurements for assessing the subjects' oral health, depression, quality of life were OHIP-14, GDS-SF and QOL. Data were collected using self-administered or interviewer-administered questionnaires. Collected data were analyzed using descriptive statistics, Pearson's correlation coefficient and stepwise multiple regression. Results: The participants' mean age was 77.68, and 86.5% were female, 42.9% were living-alone elders. Pearson's correlation coefficient analysis found that oral health impact profile was significantly associated with depression (r=-.622, p<.001), QOL (r=-.400, p<.001), number of disease (r=.298, p<.001), age (r=.198, p=.002), education (r=-.149, p=.015), eating habit (r=.185, p=.003). The QOL was explained 54.7% by depression (${\beta}$=-.619), oral health impact profile (${\beta}$=-.127), number of benefited welfare service (${\beta}$=.235), perceived health (${\beta}$=-.327), eating habit (${\beta}$=-.094) using stepwise multiple regression analysis. Conclusion: These results indicate that the intervention program of oral health promotion for community-dwelling elders is needed from now on.

  • Objective: Because the number of geriatric cancer patients is on the rise but information on treatments for this population is limited, this study aimed to analyze clinical characteristics and the factors that influence treatment decisions among elderly cancer patients.Method: Data on elderly cancer patients (≥65 years of age) who were admitted to a traditional Korean medicine hospital from March 2014 to February 2016 were collected. We compared the clinical characteristics and overall survival rates of the chemotherapy group and the non-chemotherapy group.Results: Nineteen patients were included in this study. Nine people received chemotherapy, and ten people did not receive chemotherapy due to concerns about quality of life. Age, activities of daily living (ADL) score, and Eastern Cooperative Oncology Group (ECOG) performance status all showed differences between the two groups, although median survival times did not differ significantly between the two. Compared with chemotherapy alone, traditional Korean medicine combined with chemotherapy prolonged median survival times.Conclusion: Old age and low ECOG performance status and ADL scores appear to be influential factors for the decision to undergo chemotherapy. Further studies are needed to confirm that these factors influence decisions about cancer treatment methods among geriatric cancer patients.
