A Special Building Zone, which could relieve or ignore part of the Building Act and the regulations in relevant laws, was practically established for the creation of new urban landscape, the improvement of construction technology, and the improvement of construction-related policy. However, due to the lack of understanding the Special Building Zone as well as the insufficiency of detailed standards in policies, the system currently cannot be operated in universal matters. In such circumstance, this study, which is based on the current data on the Special Building Zone defined in exiting law, attempts to analyze the multi-unit housing that has been planned by the system of Special Building Zone. Also, this study aims to derive the Special Building Zone's possibilities and implications that contribute to the improvement of landscape, so as to suggest solutions for effective improvement of the system. With the results above, solutions for the improvement of the system can be derived and summarized as the following. On the one hand, from 'planning perspective', it is necessary to improve the system in a comprehensive way with consideration of urban and local contexts. On the other hand, from 'procedure perspective', some foundation shall be prepared for a system that can allows comprehensive tasks, including the settlement of the zone, the alleviation/elimination of regulations, the approval of building's construction, the process of construction, and the monitoring.

본 시험은 L. casei, S. lactis, C. utilis, M. heimalis, S. albus, R. palustris, R. sphaeroides 통의 유용미생물이 혼합된 복합미생물 발효제를 비육돈 사료에 0.5% 및 1% 수준으로 첨가하여 급여할 경우 증체량, 사료섭취량, 사료요구율, 비육돈사내 암모니아, 황화수소 및 이산화탄소 농도에 미치는 영향을 분석하기 위하여 3처리$\times$3반복$\times$15두로서 총 135두를 공시하여 실시하였는데, 그 결과를 요약하면 다음과 같다. 1. 복합미생물 발효제 급여는 일당증체량에는 영향을 미치지 않았으나, 사료섭취량은 0.5% 급여구가 가장 낮았으며(p<0.05), 사료 요구율은 복합미생물 발효제 급여로 개선되는 경향을 나타내었고 0.5% 급여구가 가장 우수하게(p<0.05) 나타났다. 2. 복합미생물 발효제 급여가 비육돈사내 환경개선에 미치는 영향은 긍정적인 것으로 평가된다. 복합미생물 발효제 급여는 돈사내 암모니아 농도를 30% 이상 저감시키는 효과가 인정되었으며, 황화수소 농도는 복합미생물 발효제 1% 급여구에서 대조구에 비하여 뚜렷한 저감 효과를 나타내었다. 그러나 이산화탄소 농도에는 영향을 미치지 않았다. 이상의 결과를 요약해보면 비육돈에 대한 복합미생물 발효제 40일 간의 급여는 사료요구율을 개선시키고, 돈사내 암모니아 및 황화수소 농도에 영향을 미치며, 암모니아의 경우 30% 이상의 저감효과가 인정되어 복합미생물 발효제는 돈사 환경개선에 효과적인 것으로 판단된다.

Renovation of existing sports facilities or construction of temporary ones for international complex games requires a wide variety of hundreds of sub construction projects to be awarded at the same time but there are few precedents required regarding the study of tendering process required in such cases. As award of construction contracts to build sports facilities for various international complex games is a critical determinant of fate of international complex games in the initial phase, it is very critical that adequate construction tendering process bedetermined. This research is aimed to study tendering cases for renovation or construction of critical international sports facilities to enhance efficiency of facility construction and define most reasonable tendering approach to satisfy schedule constraints often associated with international complex games and contribute to improvement of international competitiveness of their host cities and propose a direction for further development. This study also provides inputs to subsequent sports events of comparable scale to minimize trial and error.

The successful project management is based on definition of project goals in construction industry. The WBS(Work Breakdown Structure) is one of the major factors which defines works related to project goals. The necessity of the WBS for owners in multi complex projects which would help them to understand the whole project is rising because the multi-complex project in the construction industry has increasing recently. Therefore, this study suggests directions to establish the WBS for owners through investigating a concept of the multi-complex project first and analyzing types of project, domestic and foreign WBS, and case studies.

Strong wind flow around a building complex was numerically studied by LES. The original motivation of this work stemmed from the efforts to develop a risk assessment technique for windstorm hazards. Lagrangian-averaged scale-invariant dynamic subgrid-scale model was used for turbulence modeling, and a log-law-based wall model was employed on all the solid surfaces including the ground and the surface of buildings to replace the no-slip condition. The shape of buildings was implemented on the Cartesian grid system by an immersed boundary method. Key flow quantities for the risk assessment such as mean and RMS values of pressure on the surface of the selected buildings are presented. In addition, characteristics of the velocity field at some selected locations vital to safety of human beings is also reported.

There are many place of business in complex building, and recently claims of noise have increased in those buildings. It is most desirable reducing the noise problems to establish the noise criteria considering the noise source and the receiving place of business, which are derived from the dose-response of noise and results of the actual condition. The degree of response to the transmission noise could be changed with background noise level in the receiving stores. In this research, the subjective evaluation for three different background level in receiving place of business or rooms were investigated from subjective tests. The eight business sound source including aerobic music were used for the test.

The purpose of this study is to evaluate the stack effect reduction alternatives in tall complex buildings in cold climates. The main problems in tall buildings occur in elevators. Such problems as elevator doors that do not close and exhaust airflows result in excessive pressure differences across elevator doors due to stack effect. Under the expected conditions causing these pressure differences, Field measurements are performed in three tall buildings. Each result of the measurements is analyzed in architectural design aspects. With these analysis, building design guidelines are proposed and analyzed by field measurements and computer simulations.

This paper presents a case study using Building Information Modeling (BIM) for planning, simulating, and implementing complex site logistics in a headquarter office building construction project in Silver Spring, MD. As part of the project a prefabricated 92ft structural tube steel pedestrian connector bridge was installed between two adjacent buildings in the city of Silver Spring, MD. There were multiple significant challenges to deliver, offload, prepare, and install the connector bridge safely, on time, and with the minimum disturbances to the neighbors. BIM was of the foremost importance to visualize, simulate, analyze, improve, and communicate the site logistics plan from delivery to installation of the connector bridge. As a result of the effort, GC of the project was able to prepare a highly detailed plan, communicate it effectively to all stakeholders, and flawlessly execute the work as planned. This case study would provide a useful reference for contractors who are seeking a better planning method that enables generation of more accurate, implementable, optimized plans for complex site logistics.
