폐콘크리트양은 건설폐기물 발생량의 약 50%정도인 연간 약 500만톤 이상으로 추정하고 있다. 따라서, 건설폐기물인 폐콘크리트에 대한 적절한 기술적 처리와 재활용 시스템이 구축된다면 도로포장 및 기타 포장 하층노반재료, 재생 입도조정쇄석, 건축물의 기초재, 토목 구조물의 기초재, 공작물의 되메우기 재료 등으로 활용될 수 있어 폐기되어버릴 단순한 쓰레기가 아니라 오히려 재활용 용도를 적극 개발하여야 할 중요한 자원이라고 볼 수 있다. 본 연구의 목적은 여러가지 건설 폐기물 중에서도 재활용 가능성이 높으며 구조물 해체시 다량으로 얻어지는 폐콘크리트를 대상으로 건설공사에 재이용하기 위해 폐콘크리트 골재를 사용한 재생콘크리트의 공학적 특성을 실험을 통해 검토하고자 하는 것이다.

Explosives demolition mothod is allowed for more efficient time-saving and safer demolitioni operations as compared to conventional / mechanical demolition methods. CDI has to minimize the effects of noise, dust and various demolition hazards to the public areas, and residences that are located adjacent to the project site. CDI's explosives demolition work on the Nam san Foreigner's Apartment Complex and chosun trading Co's factory are backed by over 45 years of explosives experience in the demolition of over 6,000 structures worldwide, many of these structures are similar to the Nam san Foreigner's Apt. and Chosun trading's factory in construction and proximity to sensitive adjacent exposures. Recoginized worldwide as the founder of the leader in explosives demolitioni technology, CDI always will applied "State-of-the-Art" explosives techniques to safely and successfully achieve the desired demolition results on these project. CDI has never injured, much less caused any fatality, to either a worker on one of our sites or to a third party during the implosion of high-rise structure.

The formal constructions of deconstructive architecture in the contemporary fashion expressed as intertexruality, difference and trace and the working of DIS and DE, and intertextuality in deconstructive has manifested itself as the intertextuality of material, hybridization of items, the blending of modes and the bi-sexuality of sexes. And the difference and trace found in fashion are fantastic and playful and come to exist as historicity. DIS and DE in fashion shows the retrogression of gravity through non-structural silhouette. Their disentring expression emerged as construction through mixture and repetition as well as overlapping of planes or spaces. And their disjuctive representation appeared in the form of mutual juxtaposition and substitution with the double-side of formal construction in fuctional terms.

1973년 창업한 (주)대우건설은 IMF 이후 지난 2000년 그룹 해체와 WORKOUT에 들어가는 어려움을 겪었다. 그러나 전 임직원이 일심단결 해서 어려움을 슬기롭게 극복하여 2005년에는 수주 8조, 1,900억원, 매출 5조 756억원, 영업이익 4,315억원으로 업계최고의 실적을 올렸다. 또한 최근 발표한 2006년 시공능력평가에서 드디어 1위로 등극해 명실상부한 최고의 건설사로 올라서는 쾌거를 달성했다. (주)대우건설은 건축, 주택, 토목, 플랜트, 해외사업 등 건설 전 분야에서 업계최고의 실적을 유지하고 있다. 특히 주택 분야에서는 푸르지오의 브랜드를 앞세워 5년 연속 주택 공급 1위의 실적을 자랑하고 있다. 2006년 (주)대우건설은 업계최고의 기술력과 영업경쟁력, 우량재무구조를 바탕으로 수주8조 5,000천억 매출 5조 5,826억원의 경영목표를 세웠으며, 이를 위해 전 임직원이 「도전과 열정」, 「자율과 책임」의 핵심 가치를 바탕으로 오늘도 매진하고 있다.

최근 지구온난화로 인한 환경 문제의 심각성이 증가하고 있다. 이에 전 산업 부문에서 지구온난화에 가장 큰 영향을 미치는 온실가스 배출량에 대한 규제를 강화하고 있다. 건설 산업에서도 온실가스 저감 대책으로 친환경 에너지 개발, 친환경 건축물 인증제도등 녹색기술의 활동이 활발히 진행 중에 있다. 그러나 이러한 활발한 연구와 노력에도 불구하고 건설공사의 각 단계별 과정에 따른 온실가스 배출량과의 이해관계를 파악하기에는 어려움이 있다. 따라서, 본 논문은 기존 연구문헌을 조사하여 건설공사 과정을 원자재 생산, 시공, 유지 및 관리, 해체 및 재활용의 단계로 구분하여, 건설공사의 각 단계에서 온실가스 배출량에 영향을 미치는 요인을 도출하고, 시스템 다이내믹스의 인과지도 작성을 통하여 온실가스 배출 원인을 분석하였다.

In order to recycled wast concrete which is occurred from demolition of the old building, it is effective that the recycled aggregate used as structural concrete aggregate. For used recycled aggregate with structural concrete, the structural capacity must be confirmed. This Study investigated bond capacity which follows in difference of absorption of the aggregate between rebar and concrete. Test results show that there are not a difference of bond strength and slip behavior according to absorption ratio of natural and recycled coarse aggregate.

Deconstruction Architecture takes various approaching ways in the plural situation of modem times while it has a common thinking way in the whole area of society, art field, etc. This plural phenomenon is expressed by collage used as a painting technique. We examine the relations of collage and Deconstruction Architecture to see what kind of space formation factor collage is applied in the Deconstruction Architecture, which can be applied to the architecture composing vocabulary, and classify the aspects that collage technique is expressed with space formation factor of Deconstruction Architecture by category. We can see that superimpositon, interpenetration, juxtaposition, scaling, open structure, undecidability, assemblage, etc. are expressed as various factors in the space of Deconstruction.

The main focus of this paper is to apply contemporary aesthetics and psychological study with interior design analysis. Up to now, the methodology of interior design analysis has been developed toward a more qualitative way. By the virtue of the perception , congnition , and information theory, which oriented toward a quantitative approach, it became possible to investigate interior space analysis to a more objective and scientific ways. The purpose of this study is to investigate Modern and Post-Modern interior - architectural style with quantitative analytical method. The subjective interior critique studied by intuitive research will be transferred to scientific way by using quantitative formula . Savoye Villa and Guardiola House were selected as study model, because each architectural works ware regarded as masterpieces of Modern and Post-Modern style. These two oppositional style model will be distinguished with mathematical quantity by calculating Iave , Hmax, and Redundancy formula.

In the early 20'c, scientific thoughts make a change the absolute and separate concept of space-time into relative concept of continual entity; a kind of ideal world. It suggests that the meaning of geometry as absolute truth with which has endowed human beings would changed to a relative meaning of accumulation in intellectual work on 'nature'. This cognitive changes appeared into absolute arts in 20'c like Cubism, Superematism or Constructivism. De Stijl movement which had recepted the relative concepts like Einstein's 'theory of relativity' as a developed thought from Newton-Cartesian cognition on the world. Abstration would be adequate method for expressing the dynamics and interrelationship between forms and for giving values to indivisual elements in a compositiov. This method had appeared Modern architectural form, as a common framework. The expression characteristics of geometrical design in Deconstructive and Experimental architecture were summerized in four features through the results of the analysis. First, the relation of architectural element and intertextuality is expressed in discontinuation of context and refusal of functional building. Second, the concept of trace expresses as connection of place, decomposing of excavation of trace, trace of axis, trace of fragments. Third, anti-gravity expression is there to express of open cubic, to outgrow of rectangular system, to outgrow of volume, to separate of ground connectiov. Fourth, the complex composition of abstracted geometric form is these to abstracted geometry about indefinite shape, to layer through the overlap and collage, to de-meaning and amusement of form through the pursuit of uncertainty, to indeterminate of formal meaning through operation and composition of similar form cause to the diverse of meaning.
