커뮤니티 컴퓨팅 (Community Computing)은 유비쿼터스 환경을 하나의 사회(Society)로 보고 이 사회 내에서 특정한 목표(Goal)가 생겼을 경우 이를 달성시키기 위해 커뮤니티(Community)라는 개념을 이용하는 컴퓨팅 방법이다. 커뮤니티 컴퓨팅에서 목표가 발생함에 따라 커뮤니티는 동적으로 생성되며, 한 커뮤니티내에 속하는 구성원(Member)들은 그 커뮤니티의 목표 달성을 위해 상호 작용한다. 기존의 커뮤니티 컴퓨팅 연구에서는 커뮤니티를 생성하고 멤버를 관리하는데 있어 서로 다른 커뮤니티 혹은 멤버 간에 충돌이 발생할 수 있다. 본 논문에서는 커뮤니티 컴퓨팅에서 발생할 수 있는 충돌요인을 제시하고 이의 해결을 위하여 커뮤니티 정책(Community Policy)에 기반한 방법을 제안하였다. 이의 구현 방법론으로 정책 표현을 위하여 많이 사용되는 Ponder 언어를 적용하는 사례를 제시하였다.

With the deepening of population aging, pension has become an urgent problem in most countries. Community smart pension can effectively resolve the problem of traditional pension, as well as meet the personalized and multi-level needs of the elderly. To predict the pension intention of the elderly in the community more accurately, this paper uses the decision tree classification method to classify the pension data. After missing value processing, normalization, discretization and data specification, the discretized sample data set is obtained. Then, by comparing the information gain and information gain rate of sample data features, the feature ranking is determined, and the C4.5 decision tree model is established. The model performs well in accuracy, precision, recall, AUC and other indicators under the condition of 10-fold cross-validation, and the precision was 89.5%, which can provide the certain basis for government decision-making.

코로나19 전염병 예방을 위한 공공장소에서의 마스크 착용이 의무화되고 있다. 그러나 사람들이 다양한 이유로 마스크를 제대로 착용하지 않아 감염에 노출되는 위험이 발생하고 있다. 이러한 방역 문제를 해결하고 본 논문은 영상을 인식하여 마스크를 쓴 얼굴과 쓰지 않은 얼굴을 검출하는 방식을 제안한다. 제안 방법은 마스크 착용자와 비착용자 얼굴 영상을 딥러닝 기반의 YOLO 네트워크로 학습하여, 마스크 착용 유무를 판별한다. 동일 YOLO 네트워크에 대해 여러가지 조건으로 학습을 수행하고, 학습에 사용되지 않은 검증 데이터를 이용해 정확도가 가장 높은 네트워크의 가중치를 선택하였다. 실험결과, 마스크 착용자는 67.2%, 미착용자는 39.8%의 판별 정확도를 보였다. 미착용자에 대해 낮은 정확도를 보인 이유는 학습 데이터의 부족으로 판단되며, 이를 보완하기 위하여 더 많은 학습데이터를 제작하여 성능을 개선시키고자 한다.

Objective : The purpose of this study was to verify the effectiveness of home-visit occupational therapy in stroke patients. Methods : Two patients with stroke who applied for home-based occupational therapy services at a health center in Seoul were enrolled. The home-visit occupational therapy program evaluates the subject's daily living, task performance, cognitive, and emotional functions, sets occupational therapy goals and plans interventions based on a client-centered approach. Occupational therapy programs consisted of 12 sessions based on the client's major problems. Results : COPM scores improved in both cases, there was an improvement in COPM scores, and in Case 2 there were improvements in MBI and K-MMSE scores. There was also an improvement in KGDS scores in Case 1. Conclusion : Home-visit occupational therapy was found to be effective in improving daily activities, cognition, and mental function of stroke patients. During home and community integration, continuous and continuous rehabilitation services need to be activated from institutional rehabilitation to community-based rehabilitation. Active home-visit occupational therapy is needed to promote physical, cognitive, mental and social access in stroke patients discharged from hospitals.

Since the 1960s, Korean welfare regime has been characterized by developmental welfare regime, of which invisible welfare programs like relation-based welfare are one of core elements. Developmental welfare regime of Korea has been dismantled after 1990s by the internal and external pressures. Focusing on the declines of relation-based welfare, this study examines the dismantle of developmental welfare regime of Korea. Since the late-1990s, the roles of inter-family income transfer and public income transfer are significant changed in terms of each share of total household income and each contribution of poverty alleviation. In other words, the role of public welfare has been growing while that of relation-based welfare has been decreased in the last twenty years. For the sake of a successful welfare regime transition in Korea, redistributional function of public welfare is quite important, but the development of reciprocal social economy and open community are also needed. Because, at this time and in this place, traditional welfare state building strategy is not proper in many aspects. However, it is impossible to achieve the development of reciprocal open community by restoration of relation-based welfare which has been already declined. This study regards enlargement of social economy or third sector as a development of reciprocal open community, and insists that cooperatives are especially worthy of notice.

Health promotion has more comprehensive approaches in recent years. Nevertheless we accept the concept of health promotion differently, we are agree on that community is the most important field in health promotion which includes population at the aspect of health policy, individual skill and, environment. And there are a number of different approaches to health promotion. In them, 'population approaches' and 'high -risk group approaches' has the most different characteristics. 'Population approaches' is equally important or more important than 'individual approaches' for maintaining and promoting population health. Almost part of this article contents is the summary of the guideline and population strategy of health promotion in Korea, 1999 - 2005. Community based health promotion program should be reinforced, integrated, comprehensive, collaborative through efficiently utilizing community resources. Recent new orientation of community health program is integrated health program, we can find this orientation at Ottawa charter 1986. Comprehensive approaches with the determinant factors for health are essential task. Physical activity is a key health determinant. The population-health approach suggests that educating people about physical activity is not enough. Individual behavior changes are important too, but need to be balanced with strategies for environmental change. Population strategy with physical activity for health promotion should be developed through improving social and physical supportive environment, linking and integrating community resources between public and private sectors in national, regional and local level. Continuous public education and social marketing should be provided through collaborating with community physical activity organization, facilities, work-places and school for increasing concern of all the people of community about physical activity. Governments, agencies and citizens should held and participate to building movement. And the strategy that various 'active for life' program should be developed, delivered, maintained and reinforced continuously. Basically, adequate and sufficient financing, developing human resources, policies and legislation would be provided and supported fully too. At last, research development and knowledge exchange are required domestically and internationally. In Korea, we had classified the category of strategic priority of physical activity programs by environmental support, life-course approach, high-risk group approach and disease group approach for physical activity program based on community health center. Community based core programs for physical activity that includes infrastructure building and establishment of supporting environment, community campaign, health promotion education and public service announcement, physical activity programs for elderly and obesity, exercise prescription program.
