Integrated construction site management using RFID(Radio Frequency Identification) and facility maintenance introducing USN (Ubiquitous Sensor Network) have been widely used in the mega construction project sites. But, the validation on performance of RFID systems after introducing those has not been carried out. Given that the use of RFID systems have been increased, the construction industry as well as other industries needs the evaluation of the RFID system. By regarding the necessities for evaluation, a research to the satisfaction and importance evaluation of RFID system from the end-users' view point for site management was conducted. Satisfaction-importance matrix of satisfaction standards and importance standards was created (organised) according to the analysis result of a survey, proposed improvement methods and analysis about the items presented by each region like areas of sustainable maintenance, maintenance, progressive improvement and priority improvement. The result would contribute to enhance the utilization of system and its performance.

The goal of this paper is to develop a regional environmental education program using a regional environment of dam, and to set up a regional education for sustainable development with applying that program to the students. This environmental education program is based on Hungerford's project, which consists of 4 subjects. They are good and bad influences of dam environment which students can experience easily in daily life. Through the volunteering activities such as discussion, search and observation, pre- and post-test, study of value, presentation and game, students can decide which is a favorable strategy for preserving dam facilities well. And they are encouraged to take part in environmental preservation and practice what they learn everyday in the community. The following are the outcomes of this environmental education program: First, students are much more interested in regional and general environmental problems than before and participate in conservation activities voluntarily. Second, students express their willingness for the prevention of water pollution in Hapcheon Dam by collecting garbages and reducing synthetic detergent. Third, students demand some measures which connect the school program to citizen groups for the prevention of water pollution in Hapcheon Dam.

Accurate assessment of $CO_2$ emission from buildings requires gathering $CO_2$ emission data of various construction materials. Unfortunately, the amount of available data is limited in most countries. This study was conducted to present the $CO_2$ emission data of concrete, which is the most important construction material in Korea, by conducting a statistical analysis of the concrete mix proportion. Finally, regression models that can be used to estimate the $CO_2$ emission of concrete in all strengths were developed, and the validity of these models was evaluated using 24 and 35MPa concrete data. The validation test showed that the error ratio of the estimated value did not exceed a maximum of 5.33%. This signifies that the models can be used in acquiring the $CO_2$ emission data of concrete in all strengths. The proposed equations can be used in assessing the environmental impact of various construction structural designs by presenting the $CO_2$ emission data of all concrete types.

This report is the summary of case studies about four quarry rehabilitation and restoration works in France and Austria. In Europe, the rehabilitation program should be prepared before quarrying, and this program should be meet with the expectations of stakeholders (owners, neighbors and NGOs), and the requirements of ecological restoration and environmental protection of the government. This program integrates the concept of sustainable development as well as the often exceptional potential for enhancing ecological diversity offered by quarries. Subsequently, the long-term rehabilitation effort is coordinated as closely as possible with quarrying operations, and finally the site is shut down, all measures are taken to ensure the long-term future of the rehabilitated site. The coordinated restoration project applicable to sections where quarrying operations are still in progress confines the working area to keep the visual impact of the quarry to a minimum. The re-established sites offer such great ecological diversity that they were classified as special plant and wildlife ecological zones. Wide range of rehabilitation alternatives offer opportunities to combine environmental preservation goals with social benefits. The actions include agriculture/forestry, recreational/educational developments and other uses.

The scientific objectives of PACRIM (Pacific Rim) are to advance the understanding of polarimetric and interferometric radar and to promote its application in environmental research designed to detect and quantify changes found in both the physical and humanly dominated ecosystems on the earth's surface. The information derived is used to more readily identify environments at risk; improve environmental decision making and the management of resources and thereby lead to the implementation of more effective and sustainable land use practices. PACRIM is a collaborative research project was organized by NASA's Mission to Planet Earth, Airborne Sciences Program; the Jet Propulsion Laboratory; CSIRO-COSSA and the Centre for Remote Sensing and GIS at the University of New South Wales. A decade of working with AIRSAR data (1993-2003) in the Australia-Asian-Pacific region has provided the opportunity for more than 400 investigators from 20 countries to collect, analyse, interpret and apply state-of-the-art radar data to earth-science studies. This has been achieved by scientists working within seven broad research themes; o Forestry and vegetation o Geology and tectonic processes o Interferometry o Disaster management o Coastal analysis o Agriculture o Urban and regional development. This paper presents an overview of the three data acquisition missions (1993,1996 and 2000) and the science research outcomes achieved from analyzing high quality radar data.

시화호 개발 시점은 1975년 농업진흥공사가 시화호 유역을 간척농지로 개발한다는 계획을 수립한 시점부터 잡을 수 있으나 건설교통부가 이 지역을 반월특수지역 개발구역으로 지정한 1986년 9월 27일로 보는 것이 타당할 것으로 본다. 1986년에 정부가 그렇게 지정한 목적은 이 지역을 방조제로 막아서 담수호를 만들어 농업용수를 공급하고 농지 조성과 수자원 확보를 기한다는 목적 및 그에 따른 수도권 인구 분산 및 도서 지역 균형 개발을 이루겠다는 것이었다. 그러나 1995년 4월 2억4천백85만 톤의 썩은 시화호 물을 서해로 당류하고 바닷물을 유입한 이래 2001년 2월 정부가 다시 해수호로 인정하기까지 이 호수는 숟한 우여 곡절과 정부의 잦은 정책 변경으로 자연 환경이 파괴되었으며 생태계 변화에 따른 인근 지역과 농작물에 많은 피해를 보았고 염색 공단에서 흘러나온 폐수로 인해 악취를 풍기는 등 오염이 심각해 완전히 실패로 돌아간 '환경실패대작'이라고 할 수 있다. 이렇게 된 데는 정책 집행 과정에서 환경오염 저해 요인에 대한 무사 안일한 대처, 비밀주의, 철저하지 못한 오폐수의 단속 등 정부 폭의 실책을 우선해서 말할 수 있다. 본 논문에서는 이런 것을 포함해서 시화호가 실패하게 된 여타 중요 요인에 대해서 알아보고 또 지속 가능한 활용방안 및 대책에 대해서 간략히 알아보고자 한다.

Recently the architectural paradigm have been changing into eco-friendly architecture as an sustainable architecture. This social background encourages the development of various methods of building applicable for eco-friendly buildings in architectural design. Among them, passive architecture is an design approach for eco-friendly design that contrasts with technology-based methods through MEP for renewable energy. This study researches the Passive Architectural Design methodology with two points of view; Passive Architectural Design Techniques as a guideline, which defines the elements to consider for passive architecture, and the project of Sejong Municipal Public Library as a case, which is to analysis the architectural design process. The purpose of this study is to propose an eco-friendly public building based on the methodology which is suitable for passive architectural design. Finally, this study suggests that the eco-friendly public building design for passive architecture should consider from the early step of design process, such as concept and building form etc. What is important for the passive architecture is not how much building can produce the natural energy but how less building consumes it to maintain.
