The purpose of this study is to examine whether family relationships of elderly single-person households affect community participation and whether these relationships differ by gender. Based on Baltes and Baltes (1990) 's selection, optimization, and compensation theory (SOC) and the argument that family members are a social capital by Prandini (2014), we test whether family relationships can affect community participation in old age. In order to verify this, single-person households were extracted from the 2017 National Survey of Living Conditions and Welfare Needs conducted by the Korea Institute for Health and Social Affairs (Male sample=370, Female sample=1770), multiple regression analysis were conducted with the dependent variables of friends·neighbors and the participation at Kyungrodang·welfare centers for the elderly. The results are as follows. In the case of men, family relations showed no significant effect on their participation in friends·neighbors, or Kyungrodang·welfare centers. However, in the case of women, the frequency of contact with family had a positive effect on the frequency of meeting friends·neighbors. Family contact frequency and child relationship satisfaction had a positive (+) effect on Kyungrodang·welfare center participation, while family meeting frequency had a negative effect on participation in Kyungrodang·welfare centers. For women, although Prandini's (2014) claim that family members are a social capital seems to be supported, it was found that the impact could vary depending on the type of community participation. In addition, practical discussions and suggestions were presented.

This study has been implemented under the two purposes. One is to critically explore how married immigrant women had experienced or experience conflicts, differentiation and so on occurred in their relations to family, neighbor, friend, organization and nation. The other is to understand married immigrant women and family through a new perspective based on a relational space of interacting trans-nation, local and nation. The results of the study are summarized as the followings. Firstly, transnational space is produced by international marriage between Korean man and foreign woman and kept (or activated ) by (non) everyday activities of married immigrant women and family. There are remittance, children's rearing and education, visits to mother's house, emotional interactions by phone and computer and so on. Secondly, multi-layered and relational local spaces have been (re)produced by married immigrant women's various activities related to family, neighbor, friend, nation and so on. Thirdly, married immigrant women's relations to nation state or government has been specifically presented (or expressed) through the acquiring of Korean nationality and government's activities of supporting multicultural family. Married immigrant women feel that their national identity between mother's nation and Korea is ambiguous and undecided.

The purpose of this study are the following two: first, to identify success level of elderly's Aging by their household types and second, to analyze the factors affecting successful aging. The results of this study are expected to be used as basic data for policy and program development for the successful life of the elderly. For this purpose, 699 single household, 1,412 couple household and 238 couple/child household data in personal survey and supplementary survey of the 4th Korean Retirement and Income Study. According to the analysis, the level of successful later life of single household is lower than that of couple or couple/children household. Multiple regression analysis was conducted to identify the factors affecting successful aging in single household. The results showed that economic activity, economic independence, housework, neighborhood affairs, family relations, and parent-child relationship were statistically significant. Economic independence, physical health, friendship, and parent-child relationship were found to affect in couple household. Physical health and friendship were found to be significant factors for successful aging in couple/child household.

모션 캡쳐 장비는 사람의 자연스러운 행동이나 동작 정보를 정밀하게 얻기 위해 널리 사용되며, 영화나 게임과 같은 콘텐츠에서 자주 활용되고 있다. 하지만 모션 캡쳐 장비가 고가이기 때문에 한번 입력받은 데이터를 모션별로 분할하고 상황에 맞게 재결합하여 사용할 필요가 있으며, 입력 데이터를 모션별로 분할하는 것은 대부분 수동으로 이루어진다. 이 때문에 캡쳐된 데이터를 자동으로 분할하기 위한 연구들이 다양하게 시도되고 있다. 기존의 연구들은 크게 전역적 특성에 대한 고려없이 이웃하는 프레임만을 고려하는 온라인 방식과 데이터를 전역적으로 고려하나 이웃하는 프레임 사이의 관계를 고려하지 않는 오프라인 방식으로 나누어진다. 본 논문에서는 온라인과 오프라인 방식을 병합한 그래프 기반의 모션 분할 방법을 제안한다. 분할을 위해 먼저 모션데이터를 기반으로 그래프를 생성하며, 그래프는 이웃하는 각 프레임사이의 유사도뿐만 아니라 시간축을 기반으로 일정시간내의 프레임들의 유사도를 모두 고려하였다. 이렇게 생성된 그래프를 분할하기 위해 분할된 모션내의 유사도 합을 최소화하고 각 모션간의 유사도는 최대화할 수 있는 normalized cuts을 이용하였다. 실험에서 제안된 방법은 기존의 오프라인 방식 중 하나인 GMM과 온라인 방식 중 하나인 국부최소값 분할 방법보다 좋은 결과를 보였으며, 이는 각 프레임 사이의 유사도뿐만 아니라 일정시간내의 유사도를 전역적으로 고려하기 때문이다.

Given that the number of people with developmental disabilities is continuously increasing in Korea, we need to pay attention to the lives of parents who rear the children with developmental disabilities. Accordingly, this study examined the effects of parenting stress on the quality of life in parents of children with developmental disabilities, and moderating effects of information application in the process. This study conducted a survey to 194 parents who rear such children in Chungnam and Chungbuk provinces. This study utilized PASW Statistics 18.0 for analysis, and the study results are as follows. First, it was found that parenting stress was more than average level, and information application was somewhat lower than average level. Quality of life was found to be lower than average level, and the level of relationship with neighborhood and emotional condition was relatively lower than other sub-factors. Second, influential factors of life quality were parenting stress, disability degree, information application, residential area, and disability type. Third, information application was found to have moderating effects on the relationship between parenting stress and quality of life. Based on such empirical analysis results, this study suggested concrete and comprehensive working strategies to improve quality of life in parents of children with developmental disabilities.

In traditional social network analysis, the betweenness centrality measure has been heavily used to identify the relative importance of nodes in terms of message delivery. Since the time complexity to calculate the betweenness centrality is very high, however, it is difficult to get it of each node in large-scale social network where there are so many nodes and edges. In this paper, we define a new type of network, called the expanded ego network, which is built only with each node's local information, i.e., neighbor information of the node's neighbor nodes, and also define a new measure, called the expended ego betweenness centrality. Through the intensive experiment with Barab$\acute{a}$si-Albert network model to generate the scale-free networks which most social networks have as their embedded feature, we also show that the nodes' importance rank based on the expanded ego betweenness centrality has high similarity with that based on the traditional betweenness centrality.

This study is to test the relationship between job stress, social support and subjective well-being among security agents. From 2. 23 to 3.30. 2009, covering a 35day period, 14 private security companies in Seoul were selected. Total 356 copies were picked up as the final sample. First, job stress of security agents showed that it was related to social support of neighbor and there's no relation to social support of family. Second, it showed that job stress of security agents negative affected on subjective well-being. Third, social support attentively affected on social well-being. Especially, it showed that the more social support by family was, the more subjective well-being was. Considering all the factors, social support by neighbors functions as an important parameter in relationship between subjective well-being and job stress among security agents.

선박의 접/이안 및 협수로 운항은 사고 위험성이 가장 높은 과정 중에 하나로, 많은 이해관계자들의 협업으로 진행된다. 하지만 날로 복잡해져가는 연안 지역에서, 접/이안 및 협수로 운항에서 가장 필요한 정보인 이웃 지형과의 거리 및 주변 선박과의 거리 정보 등을 대부분 목측에 의존하고 있어 이해관계자들 간의 정보 차이 또는 부주의로 인해 사고 위험성이 높아지고 있다. 이러한 문제를 해결하기 위해, 객체 인식 및 센서 융합 기반의 3차원 어라운드 뷰 도선지원 시스템을 개발하고자 하고 총 5년의 개발 계획에서 2차년도까지의 개발 내용을 소개하고자 한다..

The consensus algorithm has a faster convergence speed as the number of cooperating neighbors increases, but the information sharing delay in the wireless network increases due to access collisions as the number of cooperating neighbors increases. Therefore, there exists a tradeoff between these two performances according to node's coverage. In this paper, we present a method of coverage control that minimizes consensus time according to network scale.
