동시출현단어 분석을 통한 국내외 정보학 학회지 연구동향 파악
김하진,송민 한국정보관리학회 2014 정보관리학회지 Vol.31 No.1
This paper carried out co-word analysis of noun and noun phrase using text-mining technique in order to grasp the research trends on domestic and international information science articles. It was conducted based on collected titles and articles of the papers published in the Journal of the Korean Society for Information Management (KOSIM) and Journal of American Society for Information Science and Technology (JASIST) from 1990 to 2013. By dividing whole period into five publication window, this paper was organized into the following processes: 1) analysis of high frequency co-word pair to examine the overall trends of both information science articles 2) analysis of each word appearing with high frequency keyword to grasp the detailed subject 3) focused network analysis of trend after 2010 when distinctively new keyword appeared. The result of the analysis shows that KOSIM has considerable portion of studies conducted regarding topics such as library, information service, information user and information organization. Whereas, JASIST has focused on studies regarding information retrieval, information user, web information, and bibliometrics. 이 연구는 국내외 정보학 분야 학회지 동향을 파악하기 위하여 1990년부터 2013년까지 국내 정보관리학회지와 국외 JASIST의 논문 제목과 초록을 대상으로 텍스트 마이닝 기법을 통한 명사, 명사구 동시출현 분석을 수행하였다. 전 기간을 5구간으로 나누고 전체적인 동향을 살펴보기 위해 고빈도 동시출현단어를 분석하였으며, 세부 주제를 파악하기 위해 상위 키워드와 동시에 출현하는 단어를 분석하였다. 마지막으로 과거와 다르게 새로운 키워드가 등장하는 2010년 이후 동향을 중점적으로 네트워크 분석을 수행하였다. 분석 결과 전반적으로 국내의 경우 정보관리학회지는 도서관, 정보 서비스, 정보 이용자, 정보 자료 조직 주제 분야가 많이 차지하고 있었고 JASIST는 정보 검색, 정보 이용자, 웹 관련 정보학, 계량 정보학 중심으로 연구가 진행되었다.
선호가 배제된 지각적 판단에서 관찰된 선택 후 판단 변화 현상

Choice-induced preference change (CIPC) refers to a change in one’s preference after making a choice. The present experiment is the first to examine whether a similar phenomenon occurs after non-preference based choices, such as in perceptual judgments. In the first phase, participants rated the perceived degree of morphing for each face stimulus. Next, two faces that had been rated similarly were presented side by side and participants were asked to choose the face which seemed to have been morphed to a greater degree. Lastly, participants re-evaluated the perceived degree of morphing for each face again. The results showed that the ratings of chosen faces increased whereas those of rejected faces decreased. The present study suggests that CIPC may not be limited to preference-based choices, but may be generalized to non-preference based decision making as in perceptual judgments and choices. 선택 후 선호도 변화(Choice-Induced Preference Change, CIPC)는 의사결정 이후 대상에 대한 선호가 변화하는 현상을 말한다. 본 연구는 지각적 판단, 즉 선호가 배제된 선택 후에도 CIPC와 유사한 현상이 나타나는지 최초로 살펴보고자 하였다. 먼저, 첫 번째 평정 단계에서 참가자는 각 얼굴 자극의 지각된 모핑(morphing) 정도에 대한 평정을 내렸다. 이후 선택 단계에서는 평정 단계에서 비슷한 점수를 받은 두 얼굴을 나란히 제시하고, 참가자에게 둘 중 더 많이 모핑된 얼굴을 선택하도록 하였다. 마지막으로, 두 번째 평정 단계에서는 참가자가 각 얼굴의 지각된 모핑 정도에 대해 재평정하도록 하였다. 실험 결과, 참가자가 선택한 얼굴의 평정 점수는 증가한 반면, 선택하지 않은 얼굴의 평정 점수는 감소하였다. 따라서 본 연구는 CIPC로 알려진 현상이 선호에 기반한 선택에 국한되지 않고, 선택 후 판단 변화(Choice-Induced Judgment Change, CIJC) 현상으로 일반화될 가능성을 제안한다.

The purpose of this study is to find the improvement ways of TMSCs(Town Management Social Cooperatives) as a residential association to maintain and develop the effects of urban regeneration projects. Three steps are carried out to achieve this research purpose. First, the concepts, related policies, and establishment status of the town management cooperatives are investigated. Second, research items are driven to understand the management status of the town management cooperatives by reviewing documents related to the establishment and operation of the town management cooperatives and the results of previous studies. Third, the improvement plan of the town management cooperatives is presented by investigating and analyzing the size and type of members, the composition of the operating organization, business areas, and management performance of the town management cooperatives currently in operation. The results of this study are as follows. First, the checklists to survey the management status of the town management cooperatives are driven. Second, the tasks for improvement are presented through investigation on management status of the town management cooperatives in Gangneung-si. Third, a improvement plans for the town management cooperatives are driven.

Phase transition is not unique to solid state systems or homogeneous molecular systems but it is also observed in highly heterogeneous biological systems. Phase transition and phase separation in cells are recently being found to be central to many biological functions by temporarily and locally controlling the storage and exchange of certain proteins and RNAs. There are also clues suggesting them to be playing pivotal roles in the spatial organization of chromosomes into topological domains and its time-dependent control. Here we introduce early efforts to explain at the molecular level how the spatiotemporal organization of chromosomes are programmed and modulated by the sequence and chemical modifications of the DNA. Continuing works may provide a physical framework to understand the molecular level control of chromosome structure and dynamics that determine the epigenetic state and the fate of the cells.

As hospitals change continuously and rapidly, the way of growth and change becomes another important factor in the design of a hospital. The hospitals are also adapted for the continuous growth and change during their life span, because of the requirement of the hospital that changes endlessly, and develops continuously. But the ward areas built in 1970's and 80's have been expanded and reconstructed without reasonable plan of growth and change. So, there is required to the architectural planning on the remodeling strategy of the ward areas. The purpose of this study is to provide the fundamental data for the reasonable design planning and the basic principles of the construction plan in the ward remodeling. So, this study is to investigate and analyze the characteristics of the ward remodeling, the remodeling planning, and the scheduling process in terms of construction. As a result, this study would apply to design strategy for the ward remodeling of general hospitals.
