The use of Project Management Information System (PMIS) is increasing in project management industries such as construction, defense, manufacturing, software development, telecommunication, etc. It is generally known that PMIS helps to improve the quality of decision making in project management, and consequently improves the project performance. However, how much and which parts of project management performance are affected by PMIS still need to be studied further. The purpose of this study is to investigate the impact of PMIS quality on project management performance. We collected data from various project based industries such as construction, defense, manufacturing, software development and telecommunication by using survey questionnaire. PMIS quality was measured in three dimensions. They are system quality, information quality and service quality. Project management performance was measured in nine variables such as time reduction, work accuracy, cost management, etc. Statistical analyses such as multiple regression were used to analyze the data. The results showed that PMIS quality had significant impacts on the project management performance and user satisfaction. It was notable that only two dimensions out of the three PMIS quality dimensions, system quality and information quality, affected the project management performance. Also, it was found that PM performance played a mediating role between PMIS and user satisfaction, and between PMIS and reuse intention. The contribution of this research is that it helps to clarify what aspects of PMIS affect the project management performance and user satisfaction.

현재 모든 산업 분야가 급변함에 따라 건설 분야도 많은 변화를 겪고 있는데 대표적인 변화가 건설 분야에서 양적 팽창보다는 질적 수준을 높이는데 주력하고 있다는 것이다. 건설 분야에 있어서 프로젝트의 성공 여부가 기업의 생존에 직결된다고 할 수 있으며, 건설 프로젝트를 성공적으로 완수시키기 위하여 성과 측정 지표가 필요하다 국내 건설 기업들은 비용성과를 가장 우선으로 한 프로젝트를 수행하고 있지만 개별 프로젝트 성과에 대한 심도 있는 측정 및 분석 방법론에 대한 연구는 여전히 미비하다. 개별 프로젝트 성과 측정 방법으로는 린 건설을 기초로 한 성과측정 방법이 제시되어 있는데 이 성과측정 방법은 작업의 관점에서 개별 작업의 완수 유무로 측정하며 생산성, 신뢰성, 효용성의 세 가지 지표를 사용한다. 세가지 성과지표에 관한 측정은 공기에 관련하여 작업 완료 여부에만 집중하여 측정되고 평가되고 있다. 본 연구에서는 린 건설을 기초로 한 성과 측정 방법에 공사계획 신뢰도와 가중치 그리고 측정범위의 세 가지 고려사항을 개선방향으로 제시하였다. 제시된 고려사항들이 반영된다면 린 건설을 기초로 한 건설 프로젝트 성과측정 지표가 보다 객관적이고 정확한 지표가 도출될 것이다.

리모델링 공사는 신축공사와 달리 철거공사가 주공정으로 선행되어야 하는데 현행 철거공사는 개략적 수준의 철거관리계획에 의한 생산성만을 강조한 철거 형태로 인해 폐자재 재활용이 되지 않고 있어 자원낭비, 환경파괴를 가중시키고 있으며, 철거작업 중 작업자의 안전과 구조체의 안전등이 전혀 고려되지 않고 철거하는 것이 현실이다. 따라서 친환경 철거공사가 되기 위해서는 프로세스의 개선이 우선 되어야하며 그 단계를 1) 철거관련 조사분석, 2) 철거관리 도서작성, 3) 철거관리 시공계획서작성, 4) 철거시공 및 감리, 5) 철거 후 관리의 5단계로 구분하였으며, 특히 철거도면 작성으로 표준철거 WBS가 구축되고, 철거장비 및 공법, 폐기물 투하, 철거공정계획 수립이 가능하며 마감재 철거 후 구조체의 안전점검을 실시하므로써 철거중 불가피한 보수보강이 가능하며, 철거완료 Check list 작성에 따라 리모델링 본 공사의 Database 활용이 가능하게 되었다. 본 논문에서는 현행 리모델링 철거공사 프로세스(AS-IS)의 문제점을 분석하고 개선된 친환경 리모델링 철거공사 프로세스(TO-BE)를 IDEF0 모델을 사용하여 제안하고자 한다.

Defects are the risk factors in the construction process of buildings. They cause damage, delaying the construction duration. They especially cause adverse effects on the top-down construction method. This study analyzed the degree of construction delay induced by each work type, focusing on defects in the top-down method. Then, we derived construction delay induction coefficient from different work types in order by using the severity of construction delay per defect and the occurrence probability of defect; this assessment model measures the impact of defects on construction delay for each work type. Furthermore, by comparing each work type based on the defect frequency and the construction delay induction coefficient, we found work types that need to be administered attentively. We identified that plastering work was easy to overlook, requiring caution in defect management. This study provides an efficient defect management system suitable for the buildings that are built using the top-down construction method.

In order to seek a efficiency of site cooperation and slope stabilization in a rock sloping work, it would rather take into consideration, in its importance, a concurrent performance of civil works and landscaping works than give any part a special priority. It can enable us to achieve an expanded scope of landscaping works and improvement of slope scenery via this sort of cooperation. However, this can not be achieved without assurance on the slope stabilization and scenic view of the project owner, and further via this cooperation, environmentally familiar works can be performed, becoming natural environment and minimizing damages on surrounding scenery and environment. It is foreseeable that improvement of functions of civil equipment, introduction of technology and development of landscaping materials can facilitate an improvement in the betterment of slope scenery. Landscaping related parties need to enhance their understanding of rock sloping and scenic view based on knowledge on the fundermental understanding of slope stabilization and on the base rock characteristics.

Several environmental problems have occurred and extremely affected throughout the East Asia region. Satellite imageries and spatial information have been used in the applications of environmental and natural hazard management for years. Sharing these data and resources in the community is considered as one of the optimal solution. It would consequently bring cost saving to all participated countries and eventually be beneficial to mankind as a whole. Encouraged by these factors, ASEAN＋3 Satellite Image Archive for Environmental Study project was submitted by Thailand in the 3rd Senior Official Meeting between ASEAN, China, Japan and Korea (SEOM＋3 Meeting) and approved by the SEOM＋3. The main objectives of this project are to share satellite images, information related to natural resources and environmental issues, and to provide data information services to all ASEAN＋3 countries. The proposed system is basically embedded by distributed system. The network of data users, data providers, and the center will be established using the Internet. User can access, navigate, display, and even download some archived contents. Its service site can be generally categorized into two parts, which are environmental related data archive and the Integrated satellite image catalogue. The extension of web based GIS is also planned for future development so that GIS users can conduct some preliminary analysis directly on line. This presentation will indicate scope of work, system, working scenario, and work plan of the project.
