To realize advanced collaboration environments for knowledge workers distributed geographically, there are extensive researches in ubiquitous computing environments. Especially, to cope with several known problems in traditional collaboration tools such as limited display resolution, uncomfortable shared documentation, difficult operation of collaboration environments, various approaches are attempted in the aspect of framework design. In this paper, we design a framework for collaboration environments covering hardware/software/networking architecture to flexibly coordinate a set of collaboration services and devices considering users' expectation and node capabilities. Based on the proposed framework, we develop the collaboration environment supporting the interactive networked tiled display enabling media/data sharing via networking, display interaction using pointing/tracking, and high-resolution tiled display. Finally the demonstration of the developed prototype is introduced to prove the possibility of its realization.

The objective of this study was to investigate the actual state of the national project to promote the management of Forest Management Cooperatives(FMC). To fulfil the objective, we have reviewed recent statistics, regulations, and publications related with FMC and interviewed officials and professionals engaged in FMC-related organizations. Also cognition of members on the actual state of the management of FMC's was studied by a questionnaire survey. The questionnaire was designed to get understandings of the general cognition of FMC's members associated with forest management and FMC's management activities. According to the results of the survey, more than 50% of members are not interested in forest management and most of them are not satisfied with the activity of FMC. In this paper, the results of analyses for the survey are discussed in detail. On the other hand, statistics indicate that the basic policy for FMC contributes to rapid growth in the number of local FMC's. However, the increase of FMC's has negative effect on management conditions of existing FMC's because of reduced budget allocation from the government. In addition, we concluded that some parts of current regulations for FMC are unfavorable in promoting the spontaneous management activities of local FMC's.

ITA법 제정 이후 많은 공공기관들이 ITA/EA 도입 및 구축을 추진하고 있으나, 명시적인 성과를 보여주는 경우는 많지 않은 것으로 조사되고 있다. 특히, 공공기관 EA 성숙도 수준 평가 결과 EA 도입에 비하여 관리 및 활용 영역의 수준이 낮게 나타나고 있다. 본고는 EA의 활용성을 저해하는 제 원인 중 EA 관리체계의 부실에 주목하였다. EA 도입과 함께 EA관리 체계가 수립됨에도 불구하고 EA 관리 및 활용 수준이 낮은 이유는 첫 번째로, EA관리 조직 설계 시에 EA 산출물의 작성 주체 및 협업 방안이 구체화되지 않은 상태로 관리 조직 및 역할이 수립되는 경향을 지적할 수 있다. 두번째로 EA 관리체계 설계 시에 각 EA 산출물의 특성이 고려되지 않은 획일적 관리 프로세스의 설계로 인하여 관리체계가 오작동하는 문제를 지적할 수 있다. 본 연구에서는 이러한 문제의식을 근간으로 개별 산출물에 대하여 요구되는 정확성과 정합성 수준에 따라 범정부 EA 산출물들을 구성도/정의서(Diagram/Description)형, 모델(Model)형, 정보자동생성(Auto Description)형, 설계서(Description)형, 서지정보(Metadata)형으로 유형화하고, 각각의 산출물 유형에 따른 조직의 역할과 협업 방안, 관리 프로세스를 제시하였다. 본 연구를 통해 향후 EA 관리체계 수립 및 조정 시에 산출물 유형별로 작성 주체 및 관리 조직간 요구되는 역할과 관리절차를 명확히 함으로써 효율적인 EA 산출물 관리가 이루어지도록 하고, 이를 통해 궁극적으로 EA 활용도 증진 및 EA의 근원적 목적 달성이 가능할 것으로 기대한다.

In this paper we present an improved method by using demographic information for overcoming the similarity miss-calculation from the sparsity problem in collaborative filtering recommendation systems. The similarity between a pair of users is only determined by the ratings given to co-rated items, so items that have not been rated by both users are ignored. To solve this problem, we add virtual neighbor's rating using demographic information of neighbors for improving prediction accuracy. It is one kind of extentions of traditional collaborative filtering methods using the peason correlation coefficient. We used the Grouplens movie rating data in experiment and we have compared the proposed method with the collaborative filtering methods by the mean absolute error and receive operating characteristic values. The results show that the proposed method is more efficient than the collaborative filtering methods using the pearson correlation coefficient about 9% in MAE and 13% in sensitivity of ROC.

This study, To find practical problems with the imaging of webtoons, propose their alternatives, and secure the professionalism of research along with 22 field experts including writers, directors, producers, investors and importance survey was carried out with 30 practical experts. There were four major interview areas including the stages of imaging production, investment and support for imaging, difficulties with imaging, and improvement of production methods and systems. Responses were collected from a total of 13 questions. All agreed that the biggest difficulty with imaging was a low level of collaboration, but they had different ideas about an ideal collaboration system. A low level of collaboration was mainly attributed to a shortage of professionals and lack of communication. There should be an effort to bring up such experts in three major areas including professional adaptation writers, professional IP producers, and investment agencies specialized in content.

What are the meanings of abduction as a methodology of Cultural Studies? By contextualizing Charles Sanders Peirce's logic of abduction in the discipline of Cultural Studies, I explore the epistemological discussion on the modern scientific research methodology of social sciences. Abduction is a kind of logical inference, which is often associated with guessing or intuition. Peirce's method of abduction and Cultural Studies' contextual formation in effect address an alternative methodology to positivism. Criticizing the modern Eurocentric structure of knowledge construction, I suggest that the virtue of abduction, as a logic of discovery, should be re-discovered in the context of Cultural Studies. Abduction holds important lessons for Cultural Studies as well as social sciences in general because of its focus on intuition, empathy, and intellectual collaboration. Through its elaboration of the logic of abduction, Cultural Studies is able to maintain not only its epistemological ground but also its methodological communicability.

Start-up support policy is expanding for the activation of creative economy. Domestic start-up is activated in early 2000, but is shrinked rapidly because there is not enough collaborative system of R&D, start-up, finance, and management support. Many organizations and collaborative environment in Silicon valley of USA is developed for long time. In Korea, creative economy is constructing rapidly led by government like building industrialization and information society. VCDP(Virtual Cluster-type Dynamic Collaboration Platform) is a good tool for the start-up support policy. This study explains the necessity and effectiveness of VCDP and suggests creative activation policy using this tool.

The land under Japanese-type names remains in the Korean cadastral record as an official register due to land exploitation, land and field survey programs, and the forceful name-changing system of Japan during its colonial era. This research aims to find a measure to survey and organize such land. Research details are as follows. First, this research put together the purpose and status of land exploitation in the Japanese colonial era. Japan wanted to reduce its population through agricultural emigration of the Japanese and increase food supply by producing more crops in Joseon. Therefore, land of three southern provinces, the breadbasket of Korea, was intensively plundered. Secondly, this research organized how Joseon people changed their surnames into Japanese-style ones. The initially voluntary name-changing system became mandatory and about 3.22 million households (79.3%) reported the change of their names. Thirdly, this research established a process to survey land under Japanese-style names. Fourthly, this research yielded visible outcomes as a result of the pilot program. Especially, it revealed 718 lots as land under Japanese-style names and 8 lots as land under the names of Japanese. Fifthly, this research presented internal & external collaboration and cooperation measures for surveys.

영재교육의 목표는 개인의 자아실현 및 국가 사회에 이바지하는 인재를 양성하는 데 있다. 그러나 그 동안 우리의 영재교육이 지적인 영역에 치중한 결과, 우리나라 영재의 리더십 수준은 미국의 일반 학생과 비슷하다는 분석이 제기되기도 하였다. 지적능력만 뛰어난 영재는 현대사회에서 요구하는 타인을 배려하고 소통하며 합리적 의사결정을 내릴 수 있는 인재상과는 거리가 멀다. 이에 본 논문에서는 정보영재를 위한 리더십 교육 프로그램을 개발하고 그 도구로 SNS를 활용하였다. SNS는 다양한 자료를 검색, 공유할 수 있고 사람사이의 관계 맺기, 타인과의 소통을 기반으로 하기에 리더십 교육의 목표 실현에 적합한 특징을 지녔고, 컴퓨터나 인터넷 등 첨단 기기의 사용을 즐기는 정보 영재의 특성과도 일치하는 도구이기 때문이다. 유투브, 위키피디아, 트위터 등의 SNS를 사용하여 동영상을 제작하고 간단한 메시지로 타인과 소통하며, 위키에서 협업하여 과제를 수행해나가는 과정을 통해 대인관계와 조직능력, 타인과 공동체 배려 등 리더십이 향상될 것으로 기대한다.
