Semi-industrial zone is the area where manufacturing, residential, commercial zones are mixed. Despite of their potentials in that proximity to city and convenient transportation infrastructure, a lot of semi-industrial zones in Korea have converted to other uses due to many issues such as change of industry, increasing land price, real estate speculations. Recently, local government is trying to solve their existing issues and develop them through a restoration of publicness. Now publicness is thought of as a key factor of regeneration in semi-industrial areas. In this regard, this study aims to examine the way of restoring publicness revealed in Brooklyn Navy Yard mainly focus on their urban contexts and architectural ways. Brooklyn Navy Yard, an exemplary case, is an industrial complex that has grown economically, socially and culturally through emphasizing publicness and it is evaluated as an advanced example of public industrial complex. Through the analysis of Navy Yard, this study was trying to emphasize the importance of publicness in the regeneration of semi-industrial areas and to provide implications for the Seoul Government's solutions, which are still in the conceptual stage. To analyze the publicness of the study subjects, framework and elements were derived by examining related theories and prior researches. Depending on this frame, the results of the publicness of the Navy Yard were as follows. First of all, the 'Publicness as an officiality' was identified at the characteristic of the site and Navy Yard development corporation. Second, the 'Publicness as a public interest' of the Navy Yard Development Corporation was identified in various ways of its operation methods. Finally, the 'Publicness as an accessibility' was identified in the opening of urban and architectural spaces in Navy Yard. These publicness were analyzed with seven Navy Yard's success factors. Thus, it can be interpreted that the publicness of the semi-industrial areas can contribute significantly to their success. The publicness restoring methods of Navy Yard could be used as a basic data in semi-industrial areas in the future in Korea. However they are limited to be applied directly, so extensive and in-depth research in terms of their applicability should be conducted.

기후변화로 인하여, 홍수, 사막화, 엘니뇨 등의 자연재해가 이전보다 더 발생하고 있다. 기후변화 적응은 전 세계적으로 기후변화 대응보다 중요해지고 있다. 기후변화 적응을 위한 이슈 중 하나가 물 순환이다. 각 국가에서는 물 순환을 활성화하기 위한 기술을 개발하고 있다. 특히, 저영향개발(LID, Low Impact Development)이라는 물을 확보하기 위한 정책이 각 국가별로 추진되고 있으며, 이에 따른 기술이 개발되고 있다. 국내에서도 2001년에 국토해양부는 수자원장기종합계획을 발표하고, 환경부에서는 2013년에 LID기술요소 가이드라인과 환경영향평가 시 적용 가능한 저영향개발 매뉴얼을 개발하는 등 LID기술을 개발하고 적용하기 위한 정책을 펼치고 있다. 이러한 LID기술 중 하나가 빗물 집수시스템이며, 이 빗물집수시스템은 주거지역에서 빗물을 배수하고, 집수하여 빗물을 이용하기 위해 적용되고 있다. 현재 적용되고 있는 빗물 집수시스템은 측구 집수시스템과 원형 집수시스템이 있으며, 최근에는 수로형 집수시스템이 적용되는 지역도 있다. 본 연구에서는 전과정 평가(LCA, Life Cycle Assessment)를 이용하여 빗물 집수시스템의 환경성을 평가하고자 한다. 현재, 국내에서는 녹색건축물인증, 탄소성적 표지인증, 환경성적 표지인증 등 LCA를 이용하여 환경성을 평가하고 있다. 특히, 본 연구에서는 기후변화 측면에서 LCA를 적용하여 이산화탄소배출량을 평가하고자 하였다. 본 연구의 범위는 빗물집수시스템 30m로 가정하였으며, 측구 집수시스템, 원형 집수시스템 및 수로형 집수시스템의 건설, 운영 및 유지관리, 해체 및 폐기단계의 전 과정이다. 각 빗물 집수시스템에 대해 각 단계별로 이산화탄소 배출량을 산정한 결과, 수로형 집수시스템은 $2.82\;ton\;CO_2\;eq./set$이며, 원형 집수시스템은 $27.65\;ton\;CO_2\;eq./set$, 측구 집수시스템은 $21.54\;ton\;CO_2\;eq./set$이 배출되었다. 이산화탄소배출량 측면에서는 수로형 집수시스템이 나머지 두집수시스템보다 87~90%가 저감되는 것으로 나타났다. 본 연구는 저영향개발에 대응하는 동시에 기후변화를 대응한다는 측면에서 빗물 집수시스템 정책에 활용되고, 설계시에도 반영될 수 있을 것으로 사료된다. 추가적으로 이산화탄소뿐 만 아니라, 다른 환경성을 평가하는 연구가 진행될 필요가 있다.

In this study, we analyzed the safety accidents that occurred in the apartment construction site and the correlations between the victims according to the type of work accidents through multiple correspondence analysis. There is a lack of disaster-related studies on apartment construction sites, the third most frequent building type in Korea, and most of them have used survey techniques. Therefore, the exploratory data analysis was conducted in industrial accident cause data, and derived the correlation analysis between each disaster victim through multiple correspondence analysis. The results of the study are summarized in two as follows. First, as the number of heights increased due to the high rise and complexity of apartments, the fall rate and mortality rate were high. In addition, deaths are mostly caused by very few experienced workers or those with more than 10 years of experience, resulting from safety training, lack of experience, and insensitivity to safety. Second, multi-correspondence analysis showed that most safety accidents can be prevented by wearing safety equipment, and following proper work process and its safety action. The key factors derived from this study can be used for safety education, supervision, and management in apartment construction sites.

The CM at Risk project, which started with the aim of strengthening the global competitiveness of the domestic construction industry through innovation of ordering system, is being implemented in the form of pilot projects in the public sector. However, it seems that it is necessary to enact related laws and regulations to move to the formal ordering system, and the performance analysis of the project is still insufficient. In this paper, the effectiveness and reliability of the project were verified through the performance analysis of the Pre-Construction Service of the four pilot projects currently being implemented. The results of the study were analyzed in five areas including Team Building, Design Book, Construction Period, VE, and BIM. Through the interview survey, the problems were confirmed and improvement plans were presented. The results of this study are expected to be used as basic data for the legalization of ordering system to be implemented in the future.

Most of the studies on reduction of buildings' environmental burden in the construction industry have been focused on carbon dioxide emission, although there are various kinds of environmental issues such as global warming, acidification, and etc. which are considered by many researchers. Therefore, this study defined and suggested six impact categories and the principles to assess each impact for the assessment of comprehensive environmental impacts of buildings. The six impact categories are abiotic depletion, global warming, ozone layer depletion, acidification, eutrophication, and photochemical oxidation. A case study has been conducted through comparative analysis of two structural design alternatives to confirm the necessity of assessing the six impact categories. That is, the results of global warming potential and the six impacts proposed in this study were compared. By comparing the results of only global warming potential, the second design alternative using 24MPa concrete was chosen as a better alternative, while the first design alternative using 21MPa concrete was resulted as a better alternative when six impact categories were considered. The results mean that the assessment of various environmental impacts is an appropriate and reasonable approach and the comprehensive assessment offers more reliable results of environmental impacts in the building construction.
