The domestic construction companies have implemented a various of management methodology and tools for time management. However, the work completion rate versus work plan have a big difference with the planned work completion rate previously despite of implementing the time management methodology and tools. The research searches the problems that the previous time management process and tools focusing on the management factors that can be controlled. Also, It suggest the improvement direction for these limits.

A construction manager tries to complete a construction project within its duration and budget using available resources. Schedule networks such as Bar-chart and CPM(critical path method) are used to finish the project within the duration. A survey shows that small contractors prefer Microsoft Excel to commercial time management softwares to manage construction time in their fields, because the Excel is useful to control cost with schedule and few time management experts works in the small contractors. A college produces talented graduates who are able to manage time of a construction project. But the quality and quantity of college eduction for time management is insufficient. Another survey shows that majors in Architectural engineering of local national universities have the curriculum for time management, and teach mainly the theory of network scheduling and how to make the network schedule. The several majors have classes for the theory and exercise of commercial time management softwares in several majors. It is necessary to educate time management experts able to use Bar-chart and commercial time management softwares for the small contractors.

The purpose of this study is to develop a supporting tool for efficient management, at preconstruction phase, of the schedule risk that is able to generate at construction phase. The main contents of this study to develop a practical tool are as follows. First steel work was selected as a relevant trade and a risk breakdown structure focused on the process of steel work having large effect on total construction process was made. Secondly, the work flow considering schedule risk factor was made and schedule risks that must be managed preferentially through analyzing the grade of importance for risk was selected. Finally, based on above two procedure, the management form for schedule risk was developed It is necessary to accumulate abundant data for schedule risk for other construction process and to develop a manual and a schedule risk management system.

As contemporary society becomes information-oriented, major construction companies have recently invested in information management, but small and medium ones have not. Though the small and medium companies recognize the information management is necessary and important, they don't have an ability to possess technical expertises. The purpose of this study is to develop a Schedule Risk Control System based on blogs using IT and web technologies for construction managers in small and medium construction companies. The system makes a chance to identify risk factors and prepare for responses to settle risks happened in preconstruction phases, and enables the managers and headquarters to predict and handle schedule risks by sharing information about risks on the blogs.

국내 게임 산업은 여타 문화 산업과 비교하였을 때 상업화의 시기는 가장 늦었음에도 불구하고 2002년을 기준으로 3조 4천억에 이를 정도로 급성장을 하였다 그러나 게임 제작사의 95% 이상이 적자에 시달리고 있는데 이는 게임 제작과 관련하여 개발 단계에 있어 담당자의 역할 분배 및 각 단계에 대한 적절한 관리를 하지 못해 팀원간 의사소통, 게임제작 공정 생성물 관리, 핵심 기술 및 관리 등의 문제가 발생하기 때문이다. 이러한 문제점들은 CASE 툴을 통해서 해결이 가능하다. CASE 툴을 통해 게임제작 공정에 있어 팀원간의 의사 소통과 인력 자원 관리, 공정 자료의 버전컨트롤 및 이력관리의 정보를 체계적으로 관리할 수 있도록 한다. 이에 본 논문에서는 ISO12207 과 RUP 프로세스를 기반으로 게임제작 공정의 생산성과 효율성을 증가시킬 수 있는 게임제작 지원도구(GDSS)를 설계 및 구현하였다.

It is very important to manage the risk in building construction because construction process has too many internal risk compared with others. So construction managers need more developed risk management system than the Present. While the study for the solution and management of generated risk is comparatively enough, the effort to confirm the risk of construction phase on pre-construction phase haying an major effect on total duration, is insufficient. For supporting the schedule risk management of pre-construction, this study suggests the reclassified risk breakdown structure and the investigation form for advance preparations on pre-construction Phase, which help the Poorly experienced construction manager to make more correct decisions and efficiently to execute risk management.

Scheduling management is one of the most important factors for the efficient performance of construction projects. Various computer-aided solutions for schedule management have been developed, but they are not commonly used in practice. This study conducted surveys on scheduling management methods and the related solutions to identify their status and problems in practice. Based on the results of the surveys, this study also developed a scheduling assistant program to improve the usability of scheduling management solutions. Through the developed program, the usability of scheduling management solutions will be improved in practice, thus enabling efficient scheduling management.

Cost and schedule are the major concerns for the successful construction project management. The four dimensional CAD (4D CAD) integrating graphical data and scheduling data has also been an area of research interests for improving construction controls. In order to achieve the benefits from these areas in an integrated way, this study proposes a 4D-EVMS system for the owners. Managerial requirements for cost and schedule control for the owners are identified first. A 4D-EVMS model is then proposed which provides functional flexibility in order to enhance the efficiency of the system. Lessons learned and practical implications are briefly summarize.
