Recently various applications have been proposed to improve supply chain process and management by not only using various management theories such as JIT(just In Time) and SCM(Supply Chain Management) but also utilizing emerging technology like RFID(Radio Frequency Identification). But existing research was merely focused on the use of the theories and technology on a particular work or material. Therefore, the objective of this study is to derive basic types of construction supply chain management which spans from manufacturing to installation at the construction site. This research proposes the seven types of construction supply chain processes, which has been derived based on the progress management theory and budget items for construction project. It is expected that the result of this study can be applied for RFID-based construction supply chain management as well as more efficiencies in various management areas.

One role of waterproofing work is to block external moisture and water. Defects in waterproofing work in building construction brings on huge repair costs for related construction work as well as for the waterproofing layer itself. However, we don't have a quantitative probabilistic management method for waterproofing work to successfully anticipate and prevent defects. From an analysis of the literature and prior research, defects in the waterproofing work in the underground parts of buildings occur frequently. We selected Fluid-Applied Membrane waterproofing work as representing waterproofing work in the underground parts of a building, and researched the general types and causes of defects. In this study, we developed the Relative-FMEA (Failure Mode and Effect Analysis) approach that merges the Matrix method and FMEA. From a survey of experts, we deduced the most important management factors for Fluid-Applied Membrane waterproofing work for the underground parts of buildings.

This study analyzed operating condition and the problems of damage compensation insunace (property insurance) for qualified architect and derived some suggsetions for improvement. The Certified Architects Act requires all building design and construction supervision to buy property insurance. This study proposes following suggestions to solve problems of current architect property insurance. Firstly, we need to increase the insurance purchasing rate of damage compensation insurance for qualified architect. It is necessary to clearly specify the matters concerning the submission of insurance policies by the architects, which is currently carried out by the Minister's official letter, in the form of official announcement. Secondly, proper insured amount should be adjusted. In order to insured substantial compensation capacity, total amount of insurance should be enlarged. Thirdly, the insurance period should be extended to one year after completion of building to allow compensation for accidents due to design negligence. Generally, the design defect can mostly be identified within one year after completion. Fourthly, insurance coverage should be extended. In the long run, it is essential to enlarge the scope of the security not only to property damage but also to human losses. Finally, an accident record sharing system should be established among insurance companies, so that proper insurance premiums or discounts can be made based on the system.

University campus plans include urban and spatial values and identities that they emphasize. The purpose of this study is to analyze sustainable campus policy, space, and the application to architectural planning, which UBC in Canada pursues independently from a Green Campus Certificate System. Sustainable directions and architectural components are deduced. The results are as follows: 1) the correspondence between the campus plan's goal and architectural implementation is the most important. Thus, the university must build a system for the plan's goal and a strategy to make a sustainable campus. 2) A guideline and system are requested to make many experts in various fields and stakeholders participate in the initial stage through "Design Charrette." 3) A system of virtuous circulation must be built so that feedback can be applied through the real-time comparison and verification of building energy consumption. Another goal of this study is emphasizing the necessity of campus policy and plans based on the "Living Laboratory" concept to make a sustainable city. This study could be meaningful because it supports a basis for triggering the establishment of goals for a sustainable plan and implementation in Korean universities.

Since the late 20th century, post-modern society has needed new styles in environmental design. The land art begun during that time supplied the momentum for the birth of the hybrid environmental design. The new design approach, focusing on land form and landscaping begun with land-form architecture, raised a powerful current of hybridization in the environmental design genres. The new picturesque landscape design distinguished by manipulated land forms and sublimated aesthetics appeared under the influence of land art and land-form architecture. Similarly, landscape urbanism was formed by the fusion of landscape architecture and urbanism. Therefore, the representative hybrid styles in environmental design appear as new picturesque landscape design, land-form architecture and landscape urbanism. With the new, strong interest in land and landscape, this same new interest was given to 'time' on account of the dynamics and indeterminacy of urban society. This new interest in land and time gave rise to new hybrid methodologies for environmental design such as mapping, diagramming and folding. These three tools have been applied most comprehensively in landscape urbanism. The 'fold' is the most popular design tool for most of the hybrid genres. The 'diagram' is the second-most popular design tool mostly for landscape urbanism and land-form architecture. Mapping is being actively applied to landscape urbanism and passively applied in new picturesque landscape design. In general, landscape urbanism seems to be a timely and suitable alternative for contemporary urban society. It displays very high potentials in the regeneration of the locality through the comprehensive hybrid methodology. It is necessary to actively engage in and develop landscape urbanism fit the local needs.

Considering the entire critical path, underground works in construction projects occupy a large part of the total construction period, as well as a large part of the construction costs. Particularly in the downtown area, the scale of underground work has been increasing every year. Currently, underground retaining walls, which are built at construction sites, require many skilled workers, and the works are being undertaken by means of the Euroform+Soldier system, which is quite disadvantageous in terms of the construction period. In order to complement this, forms made of new materials and new construction methods have been developed. Now more than eyer, the shortening of construction periods and the reduction of construction costs is required. Considering this, in this study, the researcher has tried to compare the Euroform+Soldier system, which has been the system most frequently used on construction sites, to the non-supporting form system, which has been used on the sites of civil engineering work. The results of the research revealed that although the Euroform+Soldier system was advantageous from the perspective of material costs, it was disadvantageous in terms of labor costs. It is thought that an additional study on a method for reducing the material costs is required, so as to revitalize the application of non-supporting forms to the construction site.

Recently, the trend has been for buildings to become larger and more sophisticated, and this has created safety issues. Because the buildings are big it takes lots of time to check building codes related to anti-disaster and safety manually, and there is the high possibility of making mistakes. Due to these problems, according to a study, 83% of architecture and construction workers believe that an automated code-checking system is needed. This study researches past automated code checking systems and research activity, and using Building Information Model (BIM) technology, determines the feasibility of developing a system to automatically check domestic codes related to egress and anti-disaster. This paper describes the necessity of an automated building code checking system and expected effects. It then reports whether the methods used in previous studies can be deployed in domestic building code checking and discusses problems and limitations. It also suggests an alternative approach. Although this study covers limited codes related to egress, we need to find out what is needed for automatic general code checking system and do further studies for that.

The building design projects which are being proceeded nowadays pursue a complex and various shape of structures, escaping from the traditional and regular shape of buildings. In this new trend of the architecture, there rises a demand of the research in the structural engineering for the effective realization of such complex-shaped buildings which disassembles the orthogonality of frames. As a distinguished characteristics of the buildings in a complex-shape, there frequently are inclined columns included in the structural frame. The inclined column causes extra axial force and bending moment at the beam-column connection so it is necessary to assess those effects on the structural behavior of the frame and the connection by experiment or analysis. However, with comparing to the studies on the normal beam-column connections, the inclined column connections have not been studied sufficiently. Therefore, this study evaluated the beam-column connections having an inclined column using nonlinear and finite element analysis method. In this paper, steel moment frames having inclined columns were analyzed by the nonlinear pushover analysis to check the global behavior and beam-column connection models were analyzed by the finite element analysis to check the buckling behavior and the fracture potentials.

우리나라는 1960년대의 경제개발계획에 따른 공업화 시축의 추진으로 산업의 발달과 경제성장은 인구를 도시로 집중시키면서 도시건축물은 대형화, 고층화, 과밀화 현상을 가져왔다. 한편, 국민생활의 향상과 산업활동의 다양화로 화재발생의 주요원인이 되는 전기, 가스, 유류등의 사용량이 해마다 늘어나고 있어 화재의 위험을 가중시키고 있다. 최근 10연간('81~'90) 전국에서 발생한 화재사고는 9만 5,154건이 발생하여 인명피해 1만1,117명, 재산피해 1,859억 2,200만원의 많은 손실을 가져 왔으며, 이 중에는 서울에서 발생한 화재가 3만6,089건으로 전체의 37.9%을 차지하고 있다. 화재가 발생할 경우 대형 참사를 방지하고 귀중한 인명피해는 물론 경제적 손실을 최저로 줄일 수 있는 소방시설을 도시건축물에 설치하여 이에 대비하는 것이 무엇보다 귀중한 일이다. 이는 화재예방 또는 발생 초기에 이를 감지, 통보하고 피난하며 소화활동에 이르는 모든 방재 및 소화를 위한 소방시설의 유용성을 최대로 발휘할 수 있기 때문이다. 본 논문에서는 서울특별시를 중심으로 도시건축물에 설치된 소방시설의 유지 관리 실태와 화재시 소방시설의 이용실태를 분석하여 문제점을 도출하고 이에 대한 개선방향을 제시하므로서 예방소방행정의 발전을 기하고저 하였으며, 그 내용을 요약하면 다음과 같다. 제1장에서는 서론부분으로서 연구의 목적과 범위및 접근 방법을 서술하였고, 제2장에서는 도시소방행정의 특성 및 소방환경의 변화로 먼저 소방행정의 의의와 도시소방행정의 유형으로 예방소방과 진압소방 그리고 구급.구조업무등을 살피고. 도시소방환경변화에 따른 화재발생추세를 살펴 보았다. 제3장에서는 도시건축물에 설치하는 소방시설의 설치.유지 및 이용실태를 검사.분석하였다. '90년도 서울시내 소방서에서 실시한 소방대상물에 대한 소방검사와 방화관리자에 대한 설문조사를 실시하여 소방시설의 유지관리실태를 통계.분석한 결과, 소방시설이 양호한 소방대상물은 전체의 75.9%이며, 불량소방대상물은 24.1%로 나타났다. 그리고 화재가 발생한 소방검사대상물에 대한 화재현장 조사결과 화재시 소방시설을 사용한 소방대상물은 전체의 72.1%를 차지하고 있다. 제4장에서 는 소방시설의 문제점으로 \circled1 소방설비부실공사, \circled2 소방시설 유지관리능력부족, \circled3 소방검사제도 불합리등이며, 이에 대한 개선방향으로 \circled1 소방설비 시공자의 지도. 감독강화, \circled2 자체시설관리능력향상, \circled3 예방소방행정제도의 개선을 제시하였다. 제5장은 결론으로, 우리나라가 최근 경제성장과 산업의 발달로 도시건축물의 화재발생 위험이 가중되면서 이에 대한 소방안전대비책이 요구된다. 이에는 도시건축물에 방화시설과 소방시설을 완비하고, 그리고 자격있고 유능한 방화관리자 선임하여 자체 소방계획을 수립하여 시설점검, 정비와 유지관리를 철저히 한다면 어떠한 화재도 예방 또는 초기에 진압할 수 있고, 또한 입주검자에 대한 소방교육 및 훈련을 지속적으로 수행하여 나간다면 여하한 도시건축물의 소방안전도 그 목적을 달성하리라고 생각한다.
