오늘날 오피스 임차수요 급증에 따른 임대료 가격의 분포와 서울시 도시공간구조 변화 행태와 연관성을 띄는지에 대해 연구 필요성이 제기되고 있다. 따라서 본 연구의 목적은 오피스 가격경사계수를 토대로 영향력을 추정하고, 도시공간구조의 동태적 변화를 계량적으로 설명할 수 있는 시계열 모형을 제시하는 것이다. 이를 규명하기 위해 금융위기 이후 2010년부터 2019년말 까지 서울시를 대상으로 지난 10년간 분기별 오피스 임대료 시세를 이용하고, 실증분석 방법론으로 수정반복매매모형을 채택하였다. 본 연구의 주된 결과를 간단히 요약·정리하면 다음과 같다. 첫째, 권역별 오피스 가격경사계수 추정결과, 공통적으로 도심권은 영향력 변동이 거의 없이 일정 수준을 유지한 반면, 강남과 여의도권의 영향력은 지속적으로 증가하였다. 이 사실은 전통적인 도심이 쇠퇴 또는 정체기 진입을, 강남과 여의도권은 꾸준한 성장세속에 부상하며 기능 분화가 이루어져, 종전 1도심 위주의 단핵에서 3대 핵심 고용 중심지의 다핵구조로 빠르게 전환되었음을 시사한다. 요컨대 이러한 현상은 궁극적으로 기업들이 공간적으로 분산 집중화가 점차 가속화됨을 의미하며, 임차인 간 네트워크 요소를 중시 여기는 경향과도 밀접한 것으로 추측된다. 둘째, 규모별로 소형과 중형은 영향력 증감이 미미한 편이나, 대형은 영향력 증가가 뚜렷하게 관찰되어 대조적인 양상이 전개되었다. 특히 중소형은 도심권과 강남, 여의도권의 가격경사계수 영향력이 반비례가 성립되어 서로 경쟁관계인 것으로 드러났다. 즉 경제적 속성인 오피스 임대료 지표로 살펴본 도시공간구조는 권역 외 규모별로도 각기 다른 특색을 지닌 이질적인 하위시장이 여실히 존재함을 알 수 있다. 아마도 규모별 도시공간구조 변화 차이는 권역 간 투자매력도나 산업 경쟁구도, 임차인의 신용도 및 선호 특성에 상당 부분 기인한 것으로 해석된다. 결론적으로 「2030 서울도시기본계획」 상의 개편된 3대 핵심권역의 서울시 중심지 체계 및 위상과 정확히 일치할 뿐더러, 다수 선행연구들이 경험적으로 주장한 가설을 뒷받침한다고 말할 수 있다. 이로써 주택 외 오피스로 조사대상을 넓히고 임대시세로 다양한 인자의 모의적용을 시도한 수정반복매매모형은 도시공간구조의 시계열적인 변화를 파악하는데 효율적이고, 대안적 접근이 될 수 있는 가능성을 충분히 확인하였다. 나아가 본 연구결과는 시장참여자들이 급변하는 대내외 환경속에서 미래 서울시 도시공간구조를 탐색·예측하고 고용 중심지를 식별함으로써, 향후 바람직한 도시성장전략을 유도하는 계획구상 및 정책수립에 도움이 될 것이다.

Recently, As the high rise buildings have been demanded due to the rising current of land price, the permanent drainage method have been applied during and after the construction as a way to reduce the buoyancy acting on the bottoms of the foundations in the basement. This method has brought about the consolidation subsidence of the ground and turned out to be the problems of sinking hole and foundation re-settlement. The representative methods to be used for extending the life cycle of the existing building structure which is tilted by the foundation re-settlement or differential settlement of the foundation can be divided into the building structures reinforcement and soil reinforcement. The purpose of this study is to analyze and present the application example of steel pipe pile method to extend the life cycle of the six -stories building tilted in a soft ground.

The utilization of underground space has recently increased with the complication of road, the rise of the land price, and the development of green technology. Underground space ranges from classical excavations to subway, underground cities, and shopping malls where there are crowds of people. At this time, government has spent a lot of money in installing various types of safety facilities for preparations of increasing potential disasters. Therefore, an effective facility management system is required. In this paper, we propose an information retrieval process to effectively extract the facilities' information based on the ontology and spatial analysis in underground space. The ontology-based searching supports hierarchical and associated results as well as knowledge sharing with hierarchy concepts. The spatial analysis based searching has "Buffer" and "Near" functions to operate on a map without understanding any property of the facility information.

Due to social problems such as the increasing of land price and the expanding of city, buildings require more complex and bigger components and structure. However, the complex and massive building projects need new technology to solve effect of local buckling and the needs for more space. Hence, Concrete Filled Tube Steel (CFT), the tube steel to hold concrete during pouring and curing of concrete procedure, which helps to reduce local buckling and space, was developed. Most researches on CFT might not be focused on the characteristic of concrete 'filled in tube but structural analysis. However, it is the essential factor to increase the strength of concrete on CFT for having efficient results. Therefore, this paper will describe how to apply CFT into the construction site through examining High Strength Concrete $(800kg/cm^2)$, the strength of core, and bleeding during pouring strategy.

Agricultural and municipal wastes arc serious nuisance. in Korea. Disposal of these wastes by land application, incineration or burial have created serious environmental problems such as air pollution and ground water contamination. Uncomposted waste materials are also potential sources of plant and soil pathogens. As available sites for waste burial become more difficult to find and air quality standards for incineration become stricter, composting as a method for treating solid wastes will become more attractive. This article discussed the recent topics on composting to further develop a rational strategy. The future of composting is developed based on the interacting factors of the price of energy and fertilizer, public policy, economic considerations, and biotechnology.
