With the development of Internet of Things (IoT) technology, the combination of ICT and medical services has been increasing to improve the quality of medical services. Using the IoTs, we can collect personal health information continuously in a patient's everyday life. We expect that this will improve the quality of medical service through analysis. However, the problem of ensuring the protection of personal information within the personal health information has been hampering the research, development, and application of such services. Other problems include lack of IoT devices and lack of user convenience for collecting health information about a patient's everyday life. Therefore, in this study, we construct a daily health information management service that can collect the health related information at any time and store this data in personal storage. This data is then only provided to the healthcare worker when necessary. We built a test bed for an IoT-based smart home platform and are currently conducting user experiments. Based on the results of this study, we are attempting to provide a high quality medical trial service based on daily health information through linkage with medical device manufacturers, medical clinics, insurance companies, etc. We expect the proposed health information management service will contribute to the revitalization of smart health care services via activating various health related IoT devices and analyzing daily health information.

현재 날로 심각해 지는 환경오염문제와 에너지 문제로 인하여 광촉매 기술이 하나의 대안으로 떠오르고 있다. 1970년대 초 일본에서 시작된 광촉매 관련 연구 개발은 90년대와 2000년대를 거쳐 오면서 다양한 상업화 과정을 시도하고 있고, 그 활용 가치가 높아 지고 있다. 광촉매 응용 기술은 일상생활에서 사용하는 각종 공기정화기, 살균기 등의 제품부터 산업계와 도시의 환경개선을 위한 수처리장치등의 적용시장이 점차로 증가하고 있다. 최근 가시광 반응 광촉매, 광촉매 고정화기술 등의 연구개발과 제품 개발이 학계와 기업을 통하여 활발히 진행되고 있으며, 이는 국가 경쟁력을 높이게 됨과 동시에 쾌적한 환경을 만드는데 큰 도움이 될 것으로 기대된다.

The purpose of this study was to investigate the caregiving stress and depression of spouses who support adults with physical disabilities, calculate the activity of daily living (ADL) of the disabled and determine the correlation of each area and the influence of their ADL on the caregiving stress and depression of spouses. This study was performed on 86 spouses of the disabled who were receiving rehabilitation treatment in two hospitals located in S and K cities from July to August 2016. According to the results, the total caregiving stress scores were $71.43{\pm}17.78$ and the economic and psychological stresses among low items were higher than the other items. The total depression score was $50.34{\pm}26.41$, which was slightly higher than the average of normal adults. The caregiving stress and depression were high for aged women, for cases of high caregiving expense and time, for young disabled and for stroke disease. Factors that affected the caregiving stress were the age of the disabled and the duration of their disability; their ADL had no influence on the caregiving stress. The result showed that the depression affected their age, disabled type and grade, and ADL. Actual policy support capable of giving economic, physical, and psychological assistance should be prepared to reduce caregiving stress and depression.

This study was conducted using non-face-to-face care technology for the elderly with mild dementia and the physically weak living in the community, as various methods of care for the elderly have been raised due to the prolonged COVID-19. The purpose of this study is a similar experimental study before and after the inequality control group to compare cognitive function, daily living activities, and the degree of depression by applying an AI robot integrated management program using. The data was collected from June 4 to September 17, 2021, and the survey results of 17 people in the experimental group and 18 in the control group were analyzed using the SPSS 25.0 program. As a result of the study, the experimental group was significant in language function, activities of daily living, and depression. In particular, the results showed a decrease in moderate to severe depression and mild depression. Cognitive function was significant with long-term care grade and daily living activity with family living together. Therefore, if such non-face-to-face care technology is introduced to the elderly care field in the 'With Corona era', it is thought that it will contribute to cognitive function training and depression reduction of the elderly.

우주는 앞에서 말한 바와 같이 인간의 새로운 활동영역으로 무한한 잠재력을 갖고 있따. 첫 인공위성이 발사된 지 반세기도 안 되었지만 오늘날 우주이용은 국가안보는 물론이고 우리의 일상생활에 있어서도 지대한 영향을 미치고 있따. 현대전의 특징은 엘빈 토플러의 저서 "전쟁과 반전쟁"에서 기술한 것처럼 전격전과 초정밀 타격전이라 할 수 있다. 우주기술은 조기경보와 전장감시, 사각 없는 통신 및 초정밀 측위(GPS)와 유도를 가능케 함으로써 현대적 군사력 건설의 핵심이 되고 있다.

In this paper, we propose a distributed model that recognize ADLs of human can be occurred in daily living places. We collect and analyze user's environmental, location or activity information by simple sensor attached home devices or utensils. Based on these information, we provide a lifecare services by inferring the user's life pattern and health condition. But in order to provide a lifecare services well-refined activity recognition data are required and without enough inferred information it is very hard to build an ADL activity recognition model for high-level situation awareness. The sequence that generated by sensors are very helpful to infer the activities so we utilize the sequence to analyze an activity pattern and propose a distributed linear time inference algorithm. This algorithm is appropriate to recognize activities in small area like home, office or hospital. For performance evaluation, we test with an open data from MIT Media Lab and the recognition result shows over 75% accuracy.

This study introduces trends on silver care implemented with the fourth industrial revolution technology, and discusses the use of digital technology for elderly health and rehabilitation by reviewing relevant literature to examine and present directions for future digital-based silver care commercialization. First, health smart home, which is a smart residential service available through digital technology or IT technology that supports independent living in your home, is available. Second, there are technical services using artificial intelligence(AI) and robots. Robots based on advanced intelligence can serve as an assistant for the health and rehabilitation of senior citizens by supporting services that enable the daily lives of senior, checking their health conditions, and high-quality medical care. For the commercialization of these silver care systems, information and services appropriate to the current situation, such as the physical ability and health status of the elderly, should be provided, and it would be desirable to gradually expand the use of essential technology to reflect the needs of the elderly in use so that the digital alienated.

The purpose of this study was to investigate the balance reaction characteristics of dementia patients. Under the object of 30 dementia patients, they were divided into moderate group and severe group and examined the correlation among Clinical test of sensory interaction and balance(CTSIB), Berg balance scale(BBS) and Bathel index(BI) according to perceptional function. As a result, CTSIB was no significant difference between severe group and very severe group and BBS was significant difference between severe group ($47.32{\pm}4.80$) and very severe group ($43.09{\pm}4.18$)(p<0.05) and BI was significant difference between severe group ($92.89{\pm}9.33$) and very severe group ($76.82{\pm}6.81$)(p<0.05) and significant correlation among perceptional function, BBS and BI(p<0.05, p<0.01). Therefore, these results should be used the base data of developing rehabilitation program or protection management for dementia patients.

The purpose of this study was to examine the effects of regular physical activity program on young children's basic motor skills and daily stress. The outdoor physical activity program was conducted with 40 participants who were divided into two groups(experimental group and control group) for 10 weeks twice a week. Results of the study were as following. The outdoor physical activity program improved young children's basic motor skills in the experiment group compared to the control group. Also it had positive effects on the reduction of daily stress in the experimental group compared to the control group. This result suggests that the physical activity program have positive effects on the development of young children's basic motor skills and the reduction of daily stress.
