그동안 많은 논란이 있었던 석면문제가 또다시 도마 위에 올랐다. 최근 아기에게 바르는 파우더를 비롯하여 화장품 등에까지 석면공포가 확산됨에 따라 환경부는 석면이 주로 건축자재(80% 이상)에 사용된 만큼 국민건강 보호를 위해 건축물에 사용된 석면의 안전한 관리가 무엇보다 중요하다고 판단, 가이드라인을 제정, 시행에 들어갔다. 가이드라인의 주요 내용은 $\Delta$건축물에 사용된 석면함유 설비 또는 자재를 조사하여 석면지도 작성 및 6개월마다 훼손 여부 평가 관리 $\Delta$석면 해체 제거작업 과정에서 석면이 비산되지 않도록 주변 대기 중 석면농도 0.01개/cc(실내공기질 권고기준) 기준 설정 $\Delta$석면 해체 제거 작업 및 폐석면 처리 시 안전한 석면관리를 위한 준수사항 등이다. 이번 가이드라인은 건축물 사용단계부터 철거 폐기까지 전 생에에 걸친 석면 관리 방법 및 기준 등을 포함하고 있어 건축물 이용자, 철거지역 인근 주민의 석면 노출 차단에 기여할 것으로 기대된다. 환경부는 가이드라인을 자치단체, 다중이용시설 관리자, 건축물 철거업체 등을 통해 널리 알리는 한편, 노동부 등 관계부처와 함께 관련제도 보완 등 건축물 석면관리 개선방안을 오는 6월까지 마련할 계획이다.

최근에 카메라를 사용하여 물체를 인식하고 수량을 측정하는 연구가 진행되고 있다. 하지만 건축 자재와 같이 인접한 동일 물체의 경우, 인식과 측정이 어려우며, 이와 관련된 연구는 부족한 실정이다. 본 논문에서는 이러한 문제를 해결하기 위해 딥러닝과 드론을 사용하는 방법을 통하여 자재 더미의 윗면과 측면의 촬영, 드론 로그를 사용하한 드론 높이와 Yaw값 획득, 영상 내 자재 종류와 영역 정보 등 미리 학습된 딥러닝 모델을 사용한 획득방법, 드론 촬영 시의 Yaw값 차이를 이용해 윗면과 측면이 공통으로 가지는 직선 검색, 자재 더미의 가로, 세로, 높이의 비율 등을 통한 각 화소 비율과 자재 개수의 영역별 가상의 체적값 분석, 드론의 화각, 높이를 사용한 체적 사진측량값 획득, 가상 체적과 사진측량법 사이의 오차 최소화 비율 등을 연구하였다.

Because of world financial crisis, The Korea domestic construction industry has been damaged hugely on material supplying work. A current domestic material supply system can't react properly on a great rise of foreign exchange rate and raw material price, so the system has a problem which is not properly supplying material. To solve this problem, a more innovative material supply work system is seriously needed than ever. So this study wants to improve material supply system for supplying material right time, right place through applying a web-based system. Applying this, overall process of material-supply-work can be done on a web-based system for immediately understanding change of ordering and warehousing by material-supply-schedule to a domestic construction field.

건축물에서 사용되는 에너지 저감을 위한 노력이 활발히 진행되고 있는 가운데 공동주택 건설시 에너지 저감형 자재를 활용하는 것이 국내 에너지 소비량을 줄이는데 효과적이다. 하지만, 에너지 저감형 자재에 대한 성능 검토 및 시공관련 자료들이 체계화되어 있지 못해 설계 및 시공 시 어려움을 겪고 있다. 이에 따라, 본 연구에서는 공동주택 에너지 저감형 자재의 재료적 특성, 상세도, 시방서 등 설계에서 시공에 이르는 자료들을 DB로 구축하기 위해 효과적인 방안들을 제시하였다.

모듀울설계는 건축의 공업화생산을 위한 수단으로서, 재래식 설계와는 달리 건축척도조정체계를 사용한 설계방법이다. 본 논문에서는 모듀울설계에 따른 건축계획의 기본적인 개념, 구조설계와의 관계 및 실제 모듀울설계를 구성하는 제요소와 도면에 대하여 설명한다. 건축공업화는 궁국적으로 양산체제를 확립시키기 위한 것이며, 양산체제를 통한 건축부품과 구조의 단순화, 표준화, 조립화에 의해 자재의 절감, 인건비의 절약, 공기의 단축, 품질관리를 도모할 수 있다.

There are considerable amount of man power and time spent for analysis and selection of various materials due to the inadequate application system and rapid searching process of material related information in each stage of building production process. Also, due to the insufficiency in recycling system of important information created for each process, they are hoarded at each task stage and project completion. As a result, because of the repetition of the similar/identical tasks on each process, it is the major reason for impeding the efficient employment of manpower of the company and decreasing competition of the company. Moreover, in selecting finish material in the project field, there are many difficulties due to the lack of technical information such as product characteristics and field applications. The construction quality also affects the profit and loss of the product which calls for a need to develop continued information management system that the finish material related examples could be shared in real time. The objective of this study is to propose a building finish material information which the real time research and application is possible to raise the productivity. TO do this, the current material information task status analysis and questionnaire research should be conducted to understand the demand of system development and reflect the result onto the system for easy access and application. Therefore, the building finish material information system for enhancement of productivity of construction task proposed in this study is expected to be utilized in enhancement of construction quality, maximization of company profit, and strengthening of company competition.

People who spend most of their day indoors are continuously exposed to internally and externally generated indoor pollutants. According to a 2022 report from the World Health Organization (WHO), air pollution is the cause of more than 7 million deaths annually worldwide, emphasizing the seriousness of indoor air pollutants. Air pollutants include nitrogen oxides (NOx), formaldehyde (HCHO), and volatile organic compounds (VOCs), which have serious effects on the human body. Photocatalyst is a material that can remove these indoor air pollutants. Photocatalysts not only have the ability to remove dust precursors, but also have antibacterial, sterilizing, and deodorizing functions, making them effective in improving indoor air quality. This study suggests areas and methods in which photocatalysts can be applied to buildings. Fields of application include interior and exterior construction materials such as concrete, as well as organic paints and ventilation devices. If appropriate utilization plans are developed, it may be possible to improve the built environment through reduced indoor and outdoor pollutant levels.

Radio Frequency Identification (RFID) technology has a significant attraction throughout various industry sites, along with the development of wireless communication technologies. The typical applications of RFID include medical, logistics, and distribution, and, specially, it is effectively applied to non-contact environments, because it employs radio waves. Although, recently, construction cases of the RFID management systems for the inventory management of the construction materials have been increased, the related researches and experiments for the reused materials are not actively performed. In this paper, we propose the RFID system with the localization function for effectively managing the reuse of the construction materials, adding to the conventional inventory management system. The proposed system consists of a RFID reader unit and a receiver unit, and the location information of the material with the attached RFID tag is obtained by estimating the position of a RFID reader. The distance value for estimating the reader position is calculated using the Received Signal Strength Indicator (RSSI) value of Zigbee, and the performance evaluation of the proposed system is performed in the indoor space of $5m{\times}5m$.

The South Korean government plans for a 37 % reduction in CO2 emissions against business as usual by 2030. Subsequently, the Ministry of Land, Infrastructure and Transport declared a 26.9 % reduction target in greenhouse gas emissions from buildings by 2020 and established the Green Standard for Energy and Environmental Design (G-SEED) to help improve the environmental performance of buildings. Construction companies often work with consulting firms to prepare for G-SEED certification. In the process, owing to inefficient data sharing and work connections, it is difficult to achieve economic efficiency and obtain certification. The objective of this study was to develop an economic model to assist contractors in achieving the required G-SEED scores for materials and resources. To do this, we automated the process for material comparison and selection on the basis of an analysis of actual consulting data, and developed a model that selects material alternatives that can meet the required scores at a minimum cost. Information on materials is input by applying a genetic algorithm to the optimization of alternatives. When the model was applied to actual data, the construction cost could be lowered by 79.3 % compared with existing methods. The economical material selection model is expected to not only reduce construction costs for owners desiring G-SEED certification but also shorten the project design time.
