한국농어촌공사에서는 과학적이고 체계적인 농업기반시설 및 용수관리로 재해를 예방하고 물관리의 효율성 증대를 위한 유지관리 종합정보시스템인 농업기반시설관리시스템을 구축하여 운영중에 있다. 한국농어촌공사는 2012년부터 저수지별 일공급량을 측정하여 기록 관리하고 있어, 저수지의 수위차와 공급량을 사용하여 저수지의 일유입량을 산정 할 수 있는 체계를 구축하였고 저수지 종합건전성 평가를 위해 이 자료를 사용하였다. 수량부문은 수문학적으로 하천환경 및 수생태계에 민감한 영향을 끼치는 인자들로 지표를 구성하였다. 선정된 지표는 High Flow, Low Flow, Seasonality, Zero Flow, Variability로 구성하였다. 수질부문은 자연적 요인과 사회·경제적 요인 기준에 의한 분류를 통해 저수지의 건전성 상태를 파악할 수 있는 지표를 선정하였다. 자연적 요인은 환경부의 수질환경기준에 제시된 항목 중 저수지 건전성을 대표할 수 있는 수온, DO, COD, SS, TN, TP 및 TOC를 선정하였다. 농업용 저수지 수량·수질을 고려한 수환경 평가체계 적용을 위해 적누, 이담, 송고 저수지를 선정하였다. 3개 저수지를 대상으로 수량, 수질 부문으로 나누어 부문별 건전성 및 종합건전성 평가를 수행하였다. 선정된 지표의 분석단위를 통일시키기 위하여 표준화를 수행하였으며 자료의 왜곡정도가 큰 경우에는 로그변환을 취하여 표준화를 수행하였다. 가중치 적용은 주관적인 견해가 들어갈 수 있는 전문가의 설문에 의한 방법보다는 수학적 방법을 이용한 주성분과 엔트로피 가중치 방법을 적용하였다. 최종적으로 산정된 지수에 따라 하천별 현황을 주제별, 시기별로 검토하였으며 객관적이고 이해가 쉽게 5개 등급으로 등급분류를 해 저수지별 건전성 정도를 쉽게 파악할 수 있도록 하였다.

Energy consumption of building is given a sizable portion in total national energy conservation and if current trends continues, energy conservation level will rise as level of developed country. For this reason, a basic plan is proposed for integrated management system to manage energy conservation of buildings using a link with energy information and building information. Specifically, the questionnaire investigation conducted by building energy expert is performed to determine the projects along with time schedule and demands level of management system. In addition, to investigate study on energy usage information and management situation the management architecture of energy supplier is also studied.

This paper has studied and developed a tool for water and waste-water maintenance management with which builds a database of various construction information and makes easier the report writing and data searching. The maintenance management for water and waste and water is a method and system to control a water and waste-water scientifically and structurally, and is also a combination system that connects water and waste-water construction companies with the related department of government, or local government by using a database. It has also analyzed problems on controlling method of an existing water and waste water, and explained functions to improve fallouts of a conventional system and expected effects when using the improved program.

막대한 비용을 들여 모든 건설공사에서 시행하는 지반조사의 결과물을 현재는 종이문서 형태로 각 관리주체가 개별적으로 보관하고 있어 재활용과 공유가 거의 이루어지고 있지 않은 실정이다. 이를 데이터베이스화하여 웹을 통해 서비스함으로써 효과적인 저장과 활용을 유도할 수 있다. 그 일환으로 현재 웹 기반의 지반정보 통합 D/B 시스템을 구축, 운영 중에 있다. 현재는 지방국토관리청이나 공사현장과 같이 지반정보가 발생하는 기관 및 현장을 직접 방문하여 지반조사 결과물을 수집한 후 이를 전산화와 검수를 실시해 시스템에 반영을 하는 방식으로 지반정보를 데이터베이스화하고 있지만, 많은 시간과 비용이 소요되고 수집에 한계가 있어 이를 개선하기 위한 자동화시스템의 도입이 검토되고 있다. 지반정보의 수집, 전산화, 검수, 웹서비스의 일련 과정을 보다 자동화시키고, 효과적이며, 수집범위를 획기적으로 넓힐 수 있는 방안으로 웹 기반의 입력자동화 시스템 도입, 지반정보 관리 주체의 직접 입력 지침 마련, 입력 실무자에 대한 권한 부여와 사용자 교육 등에 대한 전략을 본 연구를 통해 모색해 보았다.

The curtain wall engineering of local high-rise buildings consists of many phases such as design, curtain wail design, manufacture, procurement, construction and facility management, each of which also involves many' actors such as architect, curtain wall consultants, manufacturers, contractors, and facility managers. Moreover, the method for controlling the C/W process of each participant is needed. Eliminating wastes and problems existed in the C/W process can be more effective. What is more, it is necessary to improve the efficiency of the current process and to strengthen the competence through application of SCM to the C/W life-cycle. In addition, it is important that a ]ot of information transfer smoothly and share through information system. Therefore, this study aimed to propose the scope of application and the improvement directions in applying Supply Chain Management concept.

This study represents construction progress management model based on quality inspection process in addition to cost-schedule integration. Quality inspection process cycle, resource estimate as progress measurement parameter, hierarchical structure of schedule, and inspection lots linking quality inspection to resource estimate are addressed as four main information areas. The authors established several process models to give a structure and correlations among information elements on each of these areas. Applying the process models proposed, an information system was implemented and utilized for nuclear power plant construction. It reveals that the system achieves accurate and objective progress information in near real time with significantly reduced time and effort as well as administrative efficiencies from making quality inspection process online.

To help a owner selecting proper contractors about the specified contract, the Evaluation and Public Announcing System of the Contractor's Construction Capacity has been introduced since 1997. But, the system has been done violence to its original meaning and purpose as time went on. When annually announcing the Contractor's Construction Capacity, especially, there was frequently a large range of opinion on the issues. On that account, MLTM(Ministry of Land, Transport and Maritime Affairs) has had to make a alteration to improve those and is making efforts for a constructive policy now. The purpose of this paper is to conduct a basis study on the Integrated System after reflecting points to be considered about improvements and the current of the times.

With the development of construction information, a computerization tool for architectural process control is a necessary tool. However, the reality is that the conditions and understanding of users are not sufficient to fully utilize such a tool. In particular, it was analyzed that the reason for the negative feedback from hands-on workers regarding the current process control information system is that there is a difficulty in accessing the system for users that are not process and planning experts, due to a lack of information and technical contents at the phase of control and planning prior to the process plan. Therefore, the demands of users and a direction for the improvement of a system in terms of optimizing process control computerization were investigated, with the aim of addressing the disadvantages of the existing system and developing a professional system that is specialized in the construction industry. Therefore, it is necessary to construct an integrated WBS (IWBS) that combines WBS with CBS, and subsequently, it is judged that the most important aspect is the integrated technology of compatibility and operation of data that is linked with OBS. The process information must then deal with the changing information; in other words, the amount of construction, construction cost, and the required construction period etc., by coding data into a 4-unit index, such as a project unit (WBS Level 1), a project facility unit (WBS Level 2), a management department unit (OBS Level 1), and a control manager unit (OBS Level 2). After that, it was found that it is necessary to develop a computer system to consistently integrate process information into a management department.
