This study aimed to examine the impact of internal communication(IC) on collaborative performance(CP) and organizational effectiveness(OE), and the moderating effect of online communication tools. First, IE and RS, ISI, RS, and COMN had a significant impact on ISI, Perf, respectively. The all factors of CP affected JS and OC. Second, IE, COMN, and RS influenced OC through CC and Perf. Third, online cooperative tools for collaboration have been moderated between RS and ISI, CoW and CC, IE and Perf, Perf and JS, repectively- IE(Infromation Exchange), CoW(Collaboration Work), Communication(COMN), Relationship(RS), Information Sharing Intention(ISI), CC(Collaboration Culture), Perf(Performance), JS(job satisfactino), and OC(Organization Commiment). These results could provide one implication for the establishment and utilization of online communication collaboration tools that take into account internal communication components within the organization.

Amplified Collaboration Environment(ACE) is a display-rich project room that enables distributed teams to intensively work together to solve a complex problem. This paper presents reviews of some most important shared workspace models in real-time collaboration systems. It then describes a set of iterative design studies of evaluation the shared workspace for ACEs. The study involved small groups of users in two ACEs performed a collaborative visualization and analysis task while varying the display technology configuration. The goal of this study was to enhance intensive collaborative work in ACEs. The results showed that the participants benefited from the ability to see others' work over the high-resolution shared workspace, which helped enhance group awareness and performance.

As recent multilateral collaboration design system has been advanced, BIM based data exchange is a key factor for successful next generation building project. Even though many studies have been trying to set up a data compatibility system for collaboration, There are still a lot of problem in data exchange between design and engineering phase. Therefore, In this study, we analysis causes of problem for information exchange and suggest a IFC based Information exchange framework for improving BIM based design collaboration environment. In order to find out problems that hinder establishment of advanced open BIM information exchange, proper analysis about transition of process from current and to-be BIM based design collaboration process is important, at first. From analysis of main obstacles to information exchange, this research suggests solution plan using open API and IFC based BIM collaboration supporting system. The suggested open API solution named Integrity feedback system perform a role making up for weak point derived from IFC based data exchange. And main system suggestion about framework for IFC based information exchange reflect technological system support, requirement of function for collaboration including API/BCF plug-in.

In recent years, the global financial crisis has worsened the economic environment for small and medium-sized businesses. A great number of South Korean enterprises are having various managerial difficulties, such as insufficient funds, shortage of manpower and lack of market information. To overcome these difficulties, many experts have suggested plans to encourage cooperation among small businesses, and such cooperation has provided diverse services to complement the insufficient capabilities of the individual companies. In spite of the efforts made by government to incite cooperation, however, the businesses themselves have displayed a lack of willingness to such cooperation. Cooperation requires a series of complicated and interdependent processes and, thus, governmental support alone cannot guarantee the necessary willingness to cooperate among small businesses. This research empirically analyzed how cooperative and creative leaderships influence the willingness to cooperate among corporate members. We also empirically studied how relationships among corporate members vary in accordance with their absorptive capacity.

e-Science is for increasing the research productivity in epochal way using research resources like high performance computers, large capacity data storage, experimental instrument and researchers. For the research activities without being limited by time and space, the collaboration system is prerequisite condition. This paper shows the comparisons and analysis of features of popular collaboration systems in the point of e-Science. We considered that the number of supporting video streams, scalability and cost are main issues for the e-Science collaboration system. By these, we conclude that Access-Grid(AG) is best suitable for the e-Science collaborative research system. This paper shows the current AG status and the future way of AG.

Recently government is set to expand its policy to promote technical proposal tendering in a dimension of technical competitiveness reinforcement. Because a variety of complicated techniques are applied in technical proposal tendering and variables could be occurred in terms of cost, schedule, constructability and others when techniques are reflected on design document collaboration management among participants is considered insignificantly. So the research would determine primary management factors and presents management direction for collaboration among participants. First action for this is categorization of hindrance factors to collaboration into five factors as 'Poor work processing', 'Communication cap among participants', 'Lack of understanding about technical proposal tendering', 'Difficulty of decision making' and 'Insufficiency in managing the work data'. Second correlation analysis is conducted between the categorized factors and participants according to tasks in technical proposal tendering to figure out the correlation degree of variables. If there is a strong correlation between variables, hindrance factor in that case regarded primary management factor to collaboration and finally management direction is presented at each task.

웹툰의 양은 방대하여 사용자가 원하는 웹툰을 찾는데 어려움이 있기 때문에 체계적인 추천 시스템이 필요하다. 하지만 기존의 추천 시스템은 조회수가 많은 인기 웹툰을 추천하는 방식과 사용자와 비슷한 연령대, 성별의 사용자들이 조회한 콘텐츠를 추천해주는 인구 통계학적 추천(demographic filtering)방식, 그리고 비슷한 사용자를 분석하여 추천해주는 협업적 추천(collaborative filtering)방식에 국한되어 있어, 개인의 성향을 반영하여 추천하고 있다고 보기 어렵다. 따라서 사용자 개인의 성향을 분석하는 방식에 대한 시도가 필요하다. 본 연구에서는 이러한 한계를 극복하기 위해서 개인의 성향을 분석하는 지표로 MBTI(Myers-Briggs Type Indicator) 유형을 이용하고, 같은 MBTI 유형의 사용자간의 협업적 필터링 추천 방식을 제안하였다. 또, 협업적 필터링 방식에서 발생하는 콜드 스타트 문제와 초기 평가자 문제를 해결하는 방안을 제시하였다.

As construction projects are complicated and large in scale, a collaboration between project participants is getting more emphasized over the last few years. The collaboration tools for participants are various. but traditionally drawings and specifications have played an important role. Especially, though storage form in drawings vary in entire construction lifecycle, drawings are still important as the core factor in latest information technology streams in regard to usefulness and reusability of information. As an attempt to standardize drawings in the public construction based on CALS/EC, this study analyzes user's requirements for drawings qualitatively, and looks into drawings standards in Korea, America and Japan, and each kind of ISO standard for drawings. And this study predicts future-oriented user's requirement for drawings based on Construction CALS/EC, and presents future-oriented direction of development applicable in domestic drawing standard in construction.

To compensate signal loss due to the channel blockage in satellite communication link, we propose a cooperative communication scheme for OTM(On-The-Move) terminal in next generation satellite communication systems. The proposed scheme configures cooperation subnet with adjacent OTM terminal with the help of ground communication equipment. Shared data is spread by orthogonal spreading code, then the spread sequences are transmitted simultaneously. The receiver combines the power of received signals by EGC(Equal gain combining). The OTM terminal blockage channel is modeled by 2-state Markov chain. We evaluate the bit error rate according to the blockage channel of the channel state for the performance analysis of the proposed scheme. As a result, the proposed scheme shows better BER performance than traditional scheme with the help of subset members. In particular, the proposed scheme shows superior performance as the channel block probability is higher. However, as the number of subset members is increasing, there is a constraint because of the higher multiple access interference.
