This study is about the system for knowledge management in the Wiki-based project learning. We implement the Wiki-based project learning system which is focused on a new Web paradigm and technology development to grasp the knowledge flow of a learner effectively under a project learning condition. Implementation of the system has used a Web 2.0 technology to easily understand SECI Knowledge Management types which form the Externalization, Combination and Internalization steps. Moreover, the system structure has been designed instinctively for harmonious knowledge use or reuse. As a result of the experiment, we found out that the collaborative knowledge steps moved along the flow of project learning.

This research proposes a new risk analysis model in order to guarantee successful performance of construction projects. The risk analysis model, called Construction Risk Analysis System(CRAS), is introduced to help contractors Identify project risks through RBS and through the procedures in risk analysis model. The proposed CRAS model consists of three phases. First step, CRAS model can help contractors decide whether or not they bid for a project by analysing risks involved in the project. Second step, the influence diagraming, decision tree and Monte Carlo simulation are used as tools to analyze and evaluate project risks quantitatively. Third step, Monte Carlo simulation is used to assess risk for groups of activities with probabilistic branching and calendars. Consequently, it will help contractors identify risk elements in their projects and quantify the impact of risk on project time and cost.

Software project planning includes several processes for estimating the effort required to complete software project tasks, allocating human resources to tasks, and creating a project plan. Because software planning is becoming more complicated as the size of software projects grow, it is difficult for project managers to decide on a reasonable project plan. To help them, many automatic software project planning approaches have been proposed. The approaches all focus on minimizing project duration. But if the plan is simply to minimize the duration, without considering software quality, the plan can harm the eventual software quality. In our research to create a reasonable project plan, we consider software quality as well as duration of the project, by defining a software quality score. The project manager can plan the project to maximize software quality for a specific project duration.

A typical construction project involves participation of various parties including clients, contractors, architects, and engineers for its successful completion, and yet has intrinsic differences of interests among the participants during the project execution period. A construction management (CM) services's role is then to resolve these differences of interests among the participants during the project execution, and lead the projects to its successful completion while representing the clients' demands and interests. The use of building information modeling (BIM) is increasing recently among construction projects, and those CM service companies are experiencing difficulties applying BIM. This is because the use of BIM in construction projects suggests a quite new set of operational paradigm. The purpose of this paper is then to review the recent cases of projects which used BIM; to analyze the these projects' processes; to reengineer the design phase process based on the lessons learned from recent BIM application; and to suggest a modified design phase process model that could improve the use of BIM and related coordination operations.

Normally there is a one-time relationship between stakeholders in the construction projects. Thus, project participants are easily exposed to opportunistic behavior. According to the theory of transaction costs, a contract effectively influence the behavior of counter-party. The important role of contracts in limiting opponent opportunistic behavior has been academically acknowledged and studied in inter-firm relationships. The purpose of this study is to reveal the mediating effect of the contract on the power of the contractor in the contractor's behavior. Power is divided into mediated and non-mediated power. We surveyed construction companies' employees who have conducted construction projects. Based on the questionnaire response, we examined the influence of the Employer's power on the behavior of the contractor. Both non-mediated power and mediated power were significant for in-role and out-role behaviors. Both non-mediated power and mediated power were found to have a significant effect on the control and coordination function of contracts. The results show that the control function of the contract is significant for the in-role behavior and the extra-role behavior. Finally, the mediating effect of the contract function was significant only in the control function.

This paper presents an analysis of construction project management from supply chain management perspective to gain insight from all constituents and to identify areas of improvement. In order to suggest opportunities for improvement, interviews with the members of a typical urban office building project in US were held. Based on that, a qualitative analysis of construction projects is presented. Focusing on electrical and mechanical sub-systems, this study illustrates the roles of subcontractors, suppliers, distributors, and manufacturing representatives as well as the complexity that a general contractor fares in managing its supply chain. The author$^{\circ}\phi$s recommendations are focused on process restructuring and automation, which include some quantifiable performance measures, incentives, and their alignment with each other

Recently, Several Mega project are been performing as a multi-dimensional development project in Korea, but some problem has been revealed about deficiency of the history, experience, and skill. A multi-dimensional development project require the technology which can manage mega project to its specific at the level of program management. predicting schedule and schedule management are the most important for mega project, been performing over several years. This research shows the method of predicting and planning schedule in the early stage as a pre-study on developing a technology of schedule management. First of all, it presents the development of database considering the specific of mega project that can accumulate the history of schedule and search the schedule according to the type of single and multi building. Also it suggests the method of prediction schedule by creating scenarios according to owner requirements and cash flow, affecting schedule management in the early stage, and the shortening possibility of schedule duration using CCPM theory.

Labor work information can be converted into the useful construction information in an effort to analyze project status, measure performance, and design a new similar project plan. The labor work information can also be used to make productivity data, which can be used to analyze the relationship between 'as planned' and 'as built' in scheduling management of a project, and to calculate 'percent completion' as well as analyzing delay cause. It is require to effectively collect the labor work information base on the activities. In general, current project management heavily depends on the experience and judgment of project managers, according to the work progress. However, relying on the oかy experience and judgment of the project managers might deteriorate the transparency or reliability of the collected labor work information. The purpose of this research is thus to develop a computer-based system for monitoring the work information generated by labors input in activities using PDA and Barcode technologies, and to propose a application method of the productivity data for effective project management.

IT 융 복합 산업에서 소프트웨어가 차지하는 비중이 높아짐에 따라 프로젝트 관리는 점차 중요해지고 IT기업의 경쟁력을 결정하는 중요 요소가 되고 있다. 프로젝트 관리 중 일정 관리는 가장 기초적이고 관리적 요소가 가장 많이 들어있으며 일정 관리의 실패는 Time-To-Market을 맞추지 못한다. 일정 관리를 위해 고려해야할 문제점들은 겉으로 확인되는 진척율과 실제로 개발된 진척율의 차이, 팀원의 낭비되는 시간을 지속적 관리 등이 있음에도 현장에서는 도구 또는 파일을 통해 진행 사항을 관리하지만 세부 작업별 활동까지 연계가 되지 않아 일정 관리의 진행 상황이 명확히 드러나지 않는다. 따라서 본 논문에서는 소스코드 기반의 실시간 프로젝트 일정 관리 도구를 제안한다. 프로젝트 계획 단계에서 작업을 컴포넌트 별로 세분화되어 있을 때 이 도구를 사용하여 컴포넌트 내부 메서드의 소스코드 작성을 통해 소프트웨어 개발 진척도를 명확하게 파악하고 해당 소스 코드의 테스트를 통해 의도대로 개발이 이루어졌는지를 확인 가능하다. 그리고 피드백을 통해 개발자에게 개발 일정 및 계획 수정에 대한 알림으로 지연되는 시간 없이 수정 가능하다.
