RT (reverberation time) of outdoor spaces surrounded by multi-storey buildings depends on many designable factors such as the openness, volume and building layouts, etc. This study therefore aims to clarify the influential factors for RT in outdoor spaces surrounded by buildings with complicated topographical conditions. A series of measurements were carried out for 15 outdoor spaces in 6 apartment complexes with different building layouts. An Empirical method considering the openness, averaged ray length and building high is also suggested, to predict RT approximately in the outdoor spaces. The overall results suggest that RT in outdoor spaces of apartment complexes is significantly influenced by source-receiver distance and building layouts.

Globally the interest of large-scale structure has been increasing for the use in various social and cultural events. However various problems for building large-scale structure in South Korea are expected in terms of construction method and site management due to the lack of experience. Construction method and planning significantly affects on making decisions. There are only theoretical approach for constructing large-scale building in domestic with the limited experience of constructing constrained size structure. Through Analytic Hierarchy Process with experts, derived decision factors mostly used construction method in construction of large-scale structure. Derived factors from this study will support making decisions for field management in constructing large-scale structure.

The fact that the major cases of life casualties are from smoke in the fire accidents and the expected steep increase of skyscrapers, huge spaces, multiplexes and huge scaled underground spaces demand establishment of efficient smoke countermeasure. The architectural factors affecting the pressure field of building should be examined for the successful design and operation of smoke management system and the stack effect is one of the important factors. The field experiments on stack effect in stairwells of high-rise building with regard to open/close condition of door are carried out to evaluate the features of pressure applied to door between each compartments, i.e, stair, lobby and accommodation. The procedures and results of experiments are presented.

The construction projects contain a lot of variables and risk affecting productivity. The duration of the project must be recognized important as for quality, unit cost and safety. There is need for improving work efficiency by investigating relationship of works to prevent delay. This study focuses on analysing the delay factors of steel staircase system to suggest regression model that enables construction productivity estimation. The position of the observers and construction delay factors were expressed by the independent variable of the regression model and productivity was expressed by a dependent variable. This paper suggests quantitative productivity and it is expected that will be helpful estimating application in construction new technologies.

The hazard assessment in which the potential hazard factors In the buildings are investigated and the scale of the hazard is analyzed should be performed first in order to prevent personal and material damages due to building fire. In this study, the building fire hazard are assessed using 822-item checklist, for the qualitative evaluation of which the main factors are classified into 10 items, yielding 100 scale points with some weighting. It is shown that present model is applicable for the assessment of all general buildings through the examination of the suitability of assessment model by actual assessment of existing building. Also, the checklist is prepared in itemized questionnaire form for easy assessment of building fire hazard. Therefore, the present model will be helpful for those working in fire prevention, who are suffering from the lack of manifest evaluation model for the fire prevention assessment so far in Korea.

본 연구는 아파트 단지 내 건축물 미술작품의 스토리텔링 적용 및 확산을 위한 최초의 정량적 연구로써, 기존의 건축물 미술작품의 문제점을 보완할 대안으로 공간스토리텔링의 적용과 효과성을 알아보고자 하였다. 문헌연구를 통하여 건축물 미술작품의 신규 평가요인인 '공간스토리텔링' 세부요인을 도출하고, 건축물 미술작품에 이야기와 테마를 적용한 첫 사례인 일산 식사지구 '위시티(Wi-City)' 거주민 204명을 대상으로 설문방법을 통해 건축물 미술작품 평가요인(조형성, 환경성, 사회성, 공간스토리텔링)이 시설물 호감도와 구매의사에 미치는 영향을 검증하였다. 연구결과, 건축물 미술작품의 4가지 평가요인 중 사회성요인을 제외한 조형성, 환경성, 공간스토리텔링 요인이 시설물 호감도에 정(+)의 영향을 미치는 것으로 나타났으며, 시설물 호감도는 아파트 구매의사에 정(+)의 영향을 미치는 것으로 나타났다. 매개효과 분석 결과 조형성 요인, 환경성 요인, 사회성 요인이 구매의사에 미치는 영향관계에서 시설물 호감도는 완전매개변수로서 적합하다는 것이 입증되었으며, 공간스토리텔링요인은 부분매개 역할을 하는 것으로 나타났다.

The number of high-rise buildings has increased year after year, with there currently being 5 projects in progress to construct buildings higher than 100 stories in Seoul alone. The construction cost for such high-rise buildings is significantly higher than the cost for a conventional low-rise building, while maintenance costs are expected to be two to three times higher. To reduce the maintenance cost of a high-rise building, there is the need for a guide rail to be used for maintenance, which is why there is the need for research on the guide rail system. For this reason, as preliminary research to develop a guide rail, this study aims to derive the factors increasing construction cost by taking the installation of a guide rail into account. This is expected to lay the groundwork for the design and construction of guide rails for high-rise building maintenance.

오늘날 도시공간의 확보와 정보 집약형 도시발전을 위하여 고층 건축물의 필요성은 점점 증가하고 있다. 동시에 고층건축물 안전의 중요성이 더욱 부각되어 인위재난 중 고층건물 재난의 관심은 높아지고 있다. 본 연구에서는 전국에서 고층건물이 가장 많은 강남소방서와 가장 적게 소재한 지역에서 재난을 관할하는 중랑소방서를 선정하여 각각의 소방서 소속 현장출동 소방공무원을 설문조사를 실시하여 기술통계를 통해 고층건물 재난관리체제가 가장 잘 갖추어져 있다고 판단되는 강남소방서와 상대적으로 잘 갖추어지지 않다고 판단되는 중랑소방서로 구분하여 비교연구를 하여 고층건물 재난관리체제에 영향을 주는 요인을 실증분석하였다.

Visualized information platforms through building information modeling (BIM) such as virtual reality (VR) and augmented reality (AR) improves the efficiency of architectural information exchange. Despite that, less effort has been directed to evaluate the effectiveness of different BIM visualization platforms for architectural design review. This study fills these gaps and compares three BIM visualization tools for reviewing diverse architectural review factors and technology acceptance degree. Three main BIM visualization tools, which are desktop-based, virtual reality-based and augmented reality-based, were employed and different architectural review factors and user's technology acceptance degree was measured. As a result, VR and AR environment showed better visual presentation than desktop environment during design review. In terms of the technology acceptance level, VR and AR environments have received higher ratings compared to desktop environments. The detailed findings provide guidelines for participants and researchers involved in design review process to selectively adopt VR and AR system to various architectural design review components.

Purpose: The purpose of this study is to identify the determinants of store occupancy based on the rental characteristics of small and medium-sized enterprises (SMEs) renting buildings across the country, and to analyze the satisfaction level after opening. Research design, data and methodology: The study conducted an empirical survey through questionnaires targeting individual business owners, corporate representatives, and executives and employees nationwide, including Seoul, Gyeonggi, and other metropolitan areas and provincial cities. Results: In this study, the most important factor that SMEs consider when deciding whether to rent a commercial building or office is financial characteristics, followed by management characteristics, location characteristics, building characteristics, and facility characteristics. In addition, management characteristics were found to have the greatest impact on rental satisfaction of SMEs, followed by financial characteristics, building characteristics, and location characteristics in order. Conclusions: Since the lessor cannot immediately improve the location characteristics or building characteristics, in order to increase the rental satisfaction of small and medium-sized businesses in a relatively short period of time, it is necessary to improve managerial characteristics such as prompt civil complaint handling and clean management of the building. In addition, it is analyzed that if the factors that can reduce the burden on the tenants are found in advance and reflected in the financial characteristics, the satisfaction of the tenants can be increased.
