The planning process for roadway construction involves a large amount of information on design, construction methods, quantities, unit costs, production rates, and site conditions. Therefore, it is very important to acquire, manage, and process the necessary information efficiently to produce a rigorous construction plan. GIS (Geographic Information System) is a very effective tool for integrating and managing various types of information including spatial and non-spatial data required for roadway construction planning. This paper proposes a GIS-based system for improving roadway construction planning with its 'Interactive Space Scheduling' and 'Operation Level Planning' functions. The proposed system can assist construction planners in a unique way by integrating design and construction information and creating modularized design elements for space scheduling in real time. It is expected that the proposed system could improve the efficiency of roadway construction planning.

Modular Construction is regarded as having enhanced safety compared to traditional construction since most of modular manufacturing process in plants. Unlike general consideration for safety in modular construction, several industrial accident data and studies have pointed out that the accident rate of modular construction is not enough less as much as the practitioners have expected. It means that there is a clear need for improvement of safety management in modular construction. To enhance safety, it is necessary to identify the type and cause of accident through accident cases in order to prevent safety accident in advance. In this consideration, this study analyzed the types and causes of accidents through root cause analysis procedure with accident cases of U.S. OSHA. The classification was carried out in the order of process type, accident type and cause of accident. By following the classification criteria in this study, the causal factor was derived and the root cause map was created. Based on the analysis results, cross-analysis was conducted and it is shown that activity characteristics of modular construction are related to safety accidents. In addition, prevention methods to reduce safety accident by major activity are presented in terms of organizational, educational and technical aspects. This study contributes that the result can be used as the basic safety management in the manufacturing and construction process of modular construction.

그래픽 시뮬레이션은 건설공사의 시공계획을 위해서 매우 유용하게 쓰일 수 있으나, 토공과 같이 비정형의 물체를 다루는 경우에는 그래픽 시뮬레이션의 적용에 한계를 갖게 된다. 이러한 경우에는 사용 장비의 작업시간, 대기시간, 작업용량 등의 수치적 데이터에 근거하여 공정 전체의 생산성에 대한 분석을 수행하게 되는 수학/통계적 시뮬레이션이 그 장점을 보이지만, 프로세스 모델 구축의 어려움, 수치적 시뮬레이션 결과의 신뢰성 확보 문제 등으로 건설 분야에서의 활용이 매우 제한되어 있는 실정이다. 본 연구에서는 비정형 물체를 다루는 공사인 토공작업에 대한 시각화를 건설공사에 주로 사용되는 수학/통계적 시뮬레이션인 불연속사건 시뮬레이션(Discrete Event Simulation) 프로그램들의 출력을 분석하여 작업시간, 대기시간, 운반물량 등에 대한 수치적 결과를 건설작업의 그래픽 시각화로 표현하였다. 이를 통하여 건설공사의 시공계획 시에 시뮬레이션을 활용하면 사전에 시공과정을 수행하여 봄으로써 최적의 건설장비 및 공법을 선택하여 효율적으로 운용하게 함이 가능함을 입증하고자 하였다.

고등학교 영재학급의 학생들의 수준과 능력에 적절한 교수 학습 프로그램 개발에 대한 연구와 영재프로그램에 참여한 학생들에 대한 과정 평가의 필요성에 기반하여 본 연구는 수학 영재 학생들의 문제해결 과정에서 발현되는 창의성을 과정 중심으로 평가할 수 있는 교수 학습 사례를 제시하였다. 수학 교수 학습 소프트웨어의 일종인 GeoGebra를 활용하여 학생들이 도형을 작도하는 과정에서 GeoGebra의 인터페이스의 사용과 대수적 계산을 병행하여 다양하고 창의적 방법으로 도형을 작도하는 과정을 분석하였다. GeoGebra의 '구성단계'와 '구성단계 네비게이션 바' 기능을 활용하여 학생 개개인이 작도 과정에서 사용한 명령어, 실행 과정 및 실행 횟수를 확인하고, 이 과정에서 발견되어지는 학생들의 창의성을 도출하였다. 이를 학생 개개인의 고등학교 교육과정에 대한 선행 정도와 비교 분석하여 이러한 교수 학습 방법이 교육청 단위로 선발하는 영재교육원 뿐만 아니라 단위학교 영재학급에서도 적용 가능함을 확인하였다.

"The Act on Ubiquitous City Construction and etc." stipulates the regulations on the planning, construction and management of the u-City. As its national-level law system is about to take its effects, future new city developments are expected to have its legal basis to be built to meet u-City requirements. Also, it is anticipated that such needs would require much more planning techniques and strategies. In reaction to those upcoming needs, this study is to search for new IT infrastructure construction process of the u-City in reality. It is also to supply with the each step framework to execute the u-City projects in more structuralize and systemize manner. Therefore, with the u-City IT infra construction guide line v1.0, purpose of the establishment of comprehensive IT infrastructure construction process.

Since 1980, rapid social and economic development due to increased plant construction has led to a plant dormitory in a short period. In recent years, by the advent of the durability of dormitory remodeling is a critical need. However, user requirements due to the lack of owner's budget do not reflected. As a result, users have complained about the scope of construction, and construction stakeholder in accordance with the budget efficiency of the complaints have decreased. In this study the remodeling requirements in the planning stages is proposed for the remodeling process. In addition work type and element can select a range of construction worksheet are proposal.

The Development of Cost Management is embossed efficiently to use the budget for the construction industry. The government is exploring every efforts and polices to control increasing the budget for the construction industry. However, despite of the government's efforts, researches are insufficient for a cost management of development. Also, the changed cost of construction by frequent plan change is caused of decline in quality etc during an accomplishing project. Therefore, in this study, analyzed about principal official phase of design phase to solve the problem. In order to define clearly the target cost concepts in the planning phase apply to the DTC(Design To Cost) concept and technique at the development of cost management process which will be able to manage the enterprise expense. It's process is expected with the fact that will be the possibility efficiently of fixing target cost in the planning phase by the construction client and designer.
