In the past five years, form construction, which accounts for approximately 25% of the total construction period, has continued to occur without a significant decrease in the number of deaths, with the largest proportion of collapse accidents. Accordingly, this study analyzed the difference in perception between the manager and worker by a questionnaire survey on the degree of risk and safety management level regarding a mold collapse accident. The survey was conducted in three groups: safety manager, field worker, and field manager. The results of the survey were analyzed by an independent sample T-Test using the SPSS program. As a result, there was almost no difference in recognition between managers, but a significant difference in recognition between managers and workers. In addition, there was a difference in management perception between the administrator and worker, which clearly shows the difference in the position between the administrator who manages and supervises hazardous disaster factors and the worker who works directly in the field. Such differences in perception can be a factor that cannot be mitigated. Based on this study, more developed research can narrow the perception gap between managers and workers and be used as a basic material for disaster research.

This study tries to feel out the possibility of experimental areas of architecture which is becoming urbanization gradually through practical issues of landscape urbanism. According to this study, it is affirmed that the practical issues of landscape urbanism such as process in time, Potential territoriality of surface, practical methodology and socio-cultural imagination already have rome into the architectural area over urbanism. This is presented as characteristics of detail issues through relational density on the matrix of landscape urbanism, traces of the general landscape concepts and architectural landscapeconcepts. As a result, these practical issues and detail architectural strategies constitute the important spatial characteristics of contemporary architecture.

한국의 대형 건축사업은 공공부문과 민간 부문에서 지난 수십년간 급증하고 있는 현실이다. 그 결과 전국적으로 국제적인 건축물과 시설들이 늘어나면서 국제적 인지도도 높아가고 있다는 긍정적 측면과 더불어 여러 가지 사회적 문제점들을 만들고 있다. 특히 대형 건축사업의 시행과 설계부문에 있어 두드러진 특징은 외국 혹은 외국계 사무소의 참여가 압도적으로 많다는 것이다. 이러한 맥락에서 그 현상의 원인과 과정을 살펴보는 것은 한국의 건축문화와 사회적 현상에 내재한 문제점을 파악하고 개선하기 위해 반드시 선행되어야 할 과제가 된다.

Weight-bearing building materials are substantially weakened under high temperatures, and this is evident through the collapse of structures once engulfed by fire. Currently, there is no scientific or technological process of evaluating the real-time structural stability of a building whcih is engulfed by flame. There are many building design specifications which aim to reduce the risk of fire, but little consideration given to fire officer safety while operating in a dangerous building. This paper aims to provide direction within building policy in order to ensure the safe evacuation of fire-fighters in case of an impending building collapse. This paper suggests evaluation criteria for buildings which are damaged due to fire, autilizing current information on fire-resistant building design and a fire-resistant capacity.

Systematic and continuous monitoring and management of the energy consumption of buildings are important for estimating building energy efficiency, and ultimately aim to cope with climate change and establish effective policies for environment, and energy supply and demand policies. Globally, buildings consume 36% of total energy and account for 39% of carbon dioxide emissions. The purpose of this study is to generate three-dimensional thermo-spatial building models with photogrammetric technique using drone TIR (Thermal Infrared) images to measure the temperature emitted from a building, that is essential for the building energy rating system. The aerial triangulation was performed with both optical and TIR images taken from the sensor mounted on the drone, and the accuracy of the models was analyzed. In addition, the thermo-spatial models of temperature distribution of the buildings in three-dimension were visualized. Although shape of the objects 3D building modeling is relatively inaccurate as the spatial and radiometric resolution of the TIR images are lower than that of optical images, TIR imagery could be used effectively to measure the thermal energy of the buildings based on spatial information. This paper could be meaningful to present extension of photogrammetry to various application. The energy consumption could be quantitatively estimated using the temperature emitted from the individual buildings that eventually would be uses as essential information for building energy efficiency rating system.

Fire accidents in buildings are reported more frequently nowadays. Existing building fire accidents can lead to large-scale accidents as damage to human and physical resources increases over time, so it is necessary to quickly find ways to suppress fires and rescue them. Currently, more attention is being paid to new buildings than the existing buildings. In addition, fire information can not be captured in a real time basis for the buildings. In line with the demands of this technology, this study presents a quick and systematic fire management method to minimize damage caused by fire in buildings. As a way to achieve the purpose of the study, ArduinoTM sensors and ExcelTM and RevitTM-DynamoTM tools have been combined to develop a new fire information management system and develop a real-time 3D visualization model. It is expected to contribute to the real-time smart fire management system by proposing a fire management application as a way to utilize it in the future.

대통령 소속 국가건축정책위원회, 건축정책기본계획, 건축도시공간연구소, 공공건축가. 지금 우리 건축계를 정의하는 중요한 개념들이다. 이 모두 2007년 제정된 건축기본법에 근거한 내용으로서 당시 건설기술 건축문화선진화위원회, 건설교통부, 문화관광부의 '건축문화 선진화전략' 핵심과제였다. 그러나 '건축기본법'이 있어야 한다고 처음 주장한 사람은 김광현 서울대학교 건축학과 명예교수였다. 그가 연구책임자로서 건축기본법의 바탕을 만들었으며, 오늘의 건축계를 정의하는 건축기본법의 틀과 개념 그리고 용어의 설정도 거의 그의 구상에서 나왔다. 대한건축사협회(한명수 명예회장)와 건설기술 건축문화선진화위원회(김진애 위원장)가 이 법 제정을 위해 큰 힘을 기울였다면, 그는 이론적 기틀을 확립한 인물이다. 그는 학계에 있었지만 설계대가 제값 받기에 유독 관심이 많았다. 이유는 학생들이 사회에 나가 전문가로서 좋은 일을 할 수 있는 최대의 근거는 제대로 된 설계대가에 있다는 그의 지론 때문이었다. "학생들을 가르치는 최고의 목표는 그들이 사회에 나가 좋은 대접을 받게 하는 겁니다. 건축계에서 해야 할 가장 중요한 게 뭐냐고 지금 또 묻는다면 단언컨대 나는 제대로 된 '설계대가'라고 말할 겁니다." 김광현 명예교수는 과거 '공공발주사업에 대한 건축사의 업무범위와 대가기준'에서 '친환경건축물, 에너지효율등급' 등 추가업무에 대한 대가를 제대로 받을 수 있게 하자고 주장하고 이를 연구한 책임자이기도 했다. 그는 지금 젊은 건축사 건축교육 저변확대를 위한 '공동건축학교'를 설립해 활발히 운영 중이다. 월간 "건축사"가 국내 건축계 발전을 위해 힘써오다가 작년 2월 정년퇴임한 김광현 서울대학교 건축학과 명예교수를 3월 18일 그의 대학로 연구실에서 만났다. 그는 지난날을 회고하며 건축에 얽힌 이야기와 현재 하고 있는 일, 그리고 구상 중인 향후계획까지 다양한 이야기를 전했다.

This study reviewed the background of the advent of and the concept of age-integrated facilities where elderly persons' facilities and children's facilities have been built in the same plot or building or established adjacent to each other. And also it examined the concept, necessity, effects, and kinds of intergenerational interactions. Ten age-integrated facilities in Japan, where it is reported that intergenerational interactions are now being implemented, were selected and visited for surveys. This study implemented interviews with staff members and analyses of the drawings of the facilities to grasp the present state of age-integrated facilities and their plan types, etc. Through analyses of relationships between intergenerational interactions and the spaces in which these take place, this study discusses guidelines for space arrangement and for developing interaction space plans for age-integrated facilities that would facilitate intergenerational interactions.

최근 경주 포항 지역에 지진피해 등 대구 경북권의 잦은 재난 발생으로 인해 증대되고 있는 노후학교 건축물의 안전성 위험 문제에 대한 선제 대응이 필요한 상황이 요구되고 있다. 학교 건축물에 건물의 위험도를 파악할 수 있는 센서들을 부착하고, 실시간 모니터링을 통해 건물의 구조적 위험성을 판단한다. 건물의 위험도가 심각한 단계에 이르면 스마트폰(Smart Phone) 앱(Application)과 음성안내방송을 통해 건물의 재실자와 관리자에게 즉시 경보를 발령하며, 대피할 수 있도록 가이드를 제시 한다. 이에 본 논문에서는 스마트 재난경보방송을 위한 스마트폰 애플리케이션(application)을 통해 재난 상황을 전파하고 대응할 수 있게 건물의 위험성 발생 위치정보를 제공하며 대피 안내 정보를 제공한다. 동시에 건물의 구내방송 시스템과 연계를 통해 음성 안내방송을 자동으로 수행하며, 두 가지 방식으로 재난 메시지를 전파하여 중복성을 가지고 경보 전파를 수행한다.

The differences between this study and previous studies are as follows. First, by building a cloud-based system using IoT technology, the system was built to monitor the status of buildings in real time from anywhere with an internet connection. Second, a model for predicting the future was developed using artificial intelligence (LSTM) and statistical (ARIMA) methods for the measured time series sensor data, and the effectiveness of the proposed prediction model was experimentally verified using a scaled-down building model. Third, a method to analyze the condition of a building more three-dimensionally by visualizing the structural deformation of a building by convergence of multiple sensor data was proposed, and the effectiveness of the proposed method was demonstrated through the case of an actual earthquake-damaged building.
