[ $\lceil\;Cost Effectiveness Analysis\;\rfloor$ ] has been widely used to evaluate effectiveness of R&D resources. But, almost of cost effectiveness evaluation systems have some problems, especially estimating method of effect on R&D project is very rough and imprecise. To solve this problem, we have designed new single effect evaluation system, which are able to apply the distribution of order statistics and to transform relative measure into absolute measure for getting single effect.

Group social capital can be defined as an intangible asset that promotes knowledge sharing and social interaction. It is posited here that the group social capital raised and nurtured among group members positively influences on team performance in IS (Information Systems) development projects. And communication effectiveness is selected as a critical antecedent and its detailed relationships with the dimensions of group social capital are analyzed. Effective communication plays important role in ISD project teams by integrating knowledge from different areas. Moderating effects of project phase between the sub-dimensions of social capital and project performance are investigated. Hypotheses are tested using data from 131 project teams of 85 manufacturing firms. The results indicated that Communication effectiveness positively impacted sub-dimensions of social capital (social ties, trust, and shared vision). Moreover, the team performance is influenced by shared vision and trust, leaving social ties as a leading subcontract, as theoretically proposed in prior research. The project phase moderates the impact of shared vision on team performance.

Under increased complexity and uncertainty of overseas construction projects, it is important for construction companies to improve their own project risk management capabilities instead of risk-taking strategies to secure competitiveness in the overseas construction market. Although most of the risks occur in project execution stage, many previous studies focused on planning stage including risk identification and analysis among PRM process. Therefore, this study aims to verify the effectiveness of whole PRM process during project execution stage through empirical study on participants of overseas construction projects. As the result it was found that first, the factor directly affects the project success is the execution process of PRM. It implies that appropriate actions such as appointing charged manager for risks, timely implementation of responding plan, continuous risk monitoring and updating established plan are the key for contribution to the project success. Second, the importance of communication in PRM is also found, which is not conducted at a specific but throughout the entire PRM process and need to be managed as essential factor for successful PRM..

IT프로젝트는 구성원들간의 역할과 업무구분에 있어서 불확실성이 높은 지식서비스형 프로젝트이다. 본 연구에서는 이러한 불확실한 환경에서의 촉진행위를 설명하고 있는 사회적 상호의존성 이론의 틀에 의거하여 IT프로젝트의 상황을 실증적으로 분석하였다. 연구모델로서 목표와 업무의 상호의존성을 독립변수로 하여 촉진행위인 커뮤니케이션 효과성과 지식공유를 매개변수, 그리고 성과를 종속변수로 설정하였고 기존에 개발되어 온 항목들을 활용하여 설문을 구성하였다. 123개의 IT프로젝트에 참여하였던 개발자와 현업실무자들을 일대일 쌍으로 구성하여 데이터를 수집하였다. 분석결과 기본적으로 사회적 상호의존성 이론이 적용됨을 실증할 수 있었고 세부적으로는 지식공유가 무엇보다 중요한 매개역할을 하고 있음을 확인할 수 있었다. 커뮤니케이션 효과성은 프로젝트 성과에 직접적으로 영향을 미치기보다는 지식공유를 통하여 간접적으로 영향을 미치는 것으로 추정할 수 있었다. 목표의 상호의존성은 지식공유보다는 커뮤니케이션을 활성화시키는 효과가 있었고 지식공유는 이러한 커뮤니케이션 활성화와 더불어 업무의 상호의존성에 영향을 받아 프로젝트의 성과를 높이는 것으로 추정할 수 있었다. IT프로젝트의 실무에 있어서는 프로젝트를 성공시키기 위해서 팀 구성원들간의 지식공유를 촉진할 필요성이 확인되었다. 이러한 지식공유 활성화를 위해서는 무엇보다도 프로젝트 구성원들이 서로간의 상호의존성을 다양한 측면에서 지속적으로 확인하면서 촉진행위를 할 수 있도록 조직을 구성하고 자원을 배분하고 소통의 강도를 높여야 할 것으로 보인다.

The present study is aimed at evaluating the economic effectiveness of Abalone, haliotis discus hanai Releasing Project(ARP) conducted in the fishing ground owned by a fishing village in Ulsan, Korea. The results were summarized as follows: First, an average ratio of released abalones in the total landing after releasing is shown to be 85.0%. Second, the recapture rate of released abalones is 46.8%, exceeding the recapture rate of BEP(Break-Even-Point), 22.9%. Third, it is evaluated that total economic effectiveness of the ARP is 6.7-6.8 times, net effectiveness is 2.2-2.3 times, and the NPV(Net Present Value) discounted by a 8% interest rate is 474, 635 thousand wons, indicating the project is profitable. Considerable parts of the positive results on the ARP are based on some beneficial conditions, including the selection of favorable releasing sites, best self-regulation system of a fishing village for preservation of seaweed facilities and continued activities for protecting small abalones and their rearing. These results imply that the success of the ARP would be primarily dependent upon the selection of releasing site and effective management system after releasing.

The main purpose of this paper is to examine the aid effectiveness of ODA projects through a case of an e-Government ODA. The case at hand is the Mongolian National Data Center project, which was supported by Korea International Cooperation Agency in 2007~2009. In this paper, we analyze aid effectiveness through a case instead of a long-term macroeconomic analysis. By using OECD DAC guideline for performance evaluation of ODA project combined with PRM (Performance Reference Model) for evaluating e-Government, authors undertakes a post-implementation evaluation on the Mongolian NDC project. The result shows that the NDC project has been relevant and implemented effectively and efficiently given the political instability incurred by the election fraud in 2008. However, there have been problems as well. Provision of defected monitors was a critical problem while disagreement on the safety of the building was lasted for two more years to be settled. Some comments on the training program are also worth to hear to ameliorate similar projects. But more fundamental problems are found in impacts and sustainability areas. Low political status of ICTPA as a coordinating organization for ICT ODA and unstable job security of NDC are serious hurdles to increase effectiveness and efficiency of NDC. ICTPA has played very limited roles in coordinating government-wide ICT ODA projects because it lacks actual power and control over them. Other government organizations do not fully trust NDC as a reliable government data center due to low political status and lack of job security. Thus critical factors to affect the effectiveness and efficiency of e-Government ODA projects are political and organizational instead of economic.
