류정림,추승연,조진성,Ryu, Jung-Rim,Choo, Seung-Yeon,Jo, Jin-Sung 한국주거학회 2010 한국주거학회 논문집 Vol.21 No.4
Digital convergence era has been already started and is rapidly developed. Recently, convergency technology became an essential issue in all industries, and is expected to accelerate. This means that we can experience growth and change of architecture using new technology and approaching method. The AR (Augmented Reality) technology, among these convergence technology, is a kind of virtual reality technology that user can see a scene of real world which is overlapped by virtual world with additional information. It has been used in manufacturing and management in the whole industry fields including medical, mechanical, military field and so on because it can provide higher sense of reality. Thus, in this paper, we suggest the utilization of AR technology for organically connecting the roads, facilities, green area, landscape and others in the layout planning of housing complex. Users can see real world with virtual object by overlap computer graphic on the real world. This method provides users with various information about territoriality and openness. As the result of this study it is expected that this technology will help the layout planning of housing complex to become more reasonable in the aspect of design, time and cost.

개방형 BIM 기반 IFC 모델을 이용한 실내공간정보 시각화 도구개발 및 활용방안 연구
류정림,문선기,추승연,Ryu, Jung Rim,Mun, Son Ki,Choo, Seung Yeon 한국공간정보학회 2015 한국공간정보학회지 Vol.23 No.5
2013년 국토교통부는 부가가치와 활용도가 높은 실내공간정보를 국가 핵심 공간정보로 구축 관리하기 위하여 '기본공간정보'로 추가 지정하였으며, 이에 전국의 실내공간정보를 구축하고 관리할 수 있는 법률적 근거와 계기가 마련되었다. 하지만 측량/촬영 및 레이저스캐닝을 이용하여 실내공간정보를 구축할 경우 실내공간의 매핑으로 시각적 서비스차원의 활용은 유리하지만 시간적, 인적, 물적 자원의 소비가 크고 속성정보의 입력을 위해 추가적인 정보가공을 필요로 하는 등 유지관리 측면과 국내 AEC/FM 분야 정보의 활용이 제한적이라고 판단된다. 이에 본 연구에서는 개방형 BIM 기반의 IFC 모델을 이용하여 실내공간정보를 추출하고 이를 데이터 시각화 기술과 연계하여 이해와 표현이 쉬운 실내공간정보 시각화 방안을 마련함으로써 실내공간정보의 활용성을 높이고자 하였다. 시각화 도구는 Autodesk사의 Revit 내부 프로그램인 IFC Exporter의 오픈소스를 이용하여 실내공간정보를 추출하였으며 실내공간정보의 시각화를 위해서는 Direct3D Library를 사용하였다. 생성된 실내공간정보 객체는 XML 포맷과 상호호환이 가능하며 시설물 유지관리 분야의 COBie 연계, 항공촬영 혹은 UAV를 활용한 공간데이터베이스 구축, 대규모 군사작전 시뮬레이션, 재해/재난 발생 시 대규모 피난 시뮬레이션 등에 활용될 수 있다. 본 연구에서 제시한 실내공간정보 시각화 방안은 국가의 공간정보정책방향에 부합하고 기존 데이터에서 추출하여 생성함으로써 정보생산의 단계가 간편하다. 또한, IFC 기반의 실내공간정보 객체로써 상호운용성이 높고 정보의 편집이 용이하며 데이터의 경량성 측면에서 우수하다. MOLIT (Minister of Land, Infrastructure and Transport) authorized Indoor Spatial Information as Basic spatial information in 2013. It became a legal evidence for constructing and managing Indoor Spatial Information. Although it has a little advantage to utilize as service level that Indoor Spatial Information by laser scan or measurement, it has a lot of problems such as consuming many resources, requiring additional progresses for inputting Object Information. In conclusion, it is inefficient to utilize for the maintenance and domestic AEC/FM field. The purposes of this study is to output Indoor Spatial Information by operating IFC model which based on open BIM and to improve availability of Indoor Spatial Information with data visualization. The open-sources of IFC Exporter, a inner program of Revit (Autodesk Inc), is used to output Indoor Spatial Information. Directs 3D Library is also operated to visualize Indoor Spatial Information. It is possible to inter-operate between XML format and the objects of Indoor Spatial Information. It can be utilized in various field as well. For example COBie linkage in facility management, construction of geo-database using air-photogrammetry of UAV (Unmaned Areal Vehicle), the simulation of large-scale military operations and the simulation of large-scale evacuation. The method that is purposed in this study has outstanding advantages such as conformance with national spatial information policy, high level of interoperability as indoor spatial information objects based on IFC, convenience of editing information, light level of data and simplifying progress of producing information.

공간자료 구축을 위한 BIM/GIS 표준정보 기반 건축도시통합모델(iBUM)의 개발에 관한 기초연구
류정림,추승연,Ryu, Jung Rim,Choo, Seung Yeon 한국공간정보학회 2014 한국공간정보학회지 Vol.22 No.5
최근 건축정보 분야에서는 터널, 교량 등 도시의 인프라에도 건축정보모델링(BIM: Building Information Modeling)이 적용되면서 대형화된 도시 건축물의 유지 및 관리를 위해 BIM 뿐만 아니라 건물의 외부환경에 대한 정보가 필요하게 되었다. 또한, 건축물정보모델 및 도시/지리정보 모델 간 정보의 상호운용성을 바탕으로 다양한 시뮬레이션 및 도시계획, 국토보안 등 기타 응용프로그램에서의 상당한 이익과 발전을 가져올 수 있다는 관점에서 공간정보와 빅 데이터의 융합은 강한 잠재력을 지니고 있다. 이에 본 연구에서는 건축정보 분야의 개방형 BIM(open BIM) 표준모델인 IFC(Industry Foundation Classes)와 GIS분야의 표준모델인 CityGML의 정보를 효율적으로 연계하기 위해 IFC와 CityGML, LandXML의 정보체계 및 형상표현의 차이점을 비교분석하였으며 공간정보 분석을 위한 객체기반의 건축 도시통합모델의 개발방향을 제시하고 BIM과 GIS 간의 기초 융합전략 및 활용방안을 마련하고자 하였다. Recently, BIM(Building Information Modeling) has been applied to the infrastructure such as road and bridge, and information about the outside environment of buildings is needed for maintaining and managing the large urban facilities. In addition, the convergence between spatial information and Big-data has a large potentiality, in respect that considerable profits and developments in other application problems such as various simulations and urban plans, national land security, may be brought about on the basis of the interoperability of information between BIM and GIS. Therefore, this study attempted to suggest the development direction of a model integrating building for spatial information analysis and city on the subject by comparing and analyzing difference between information system and shape expression of IFC, CityGML and LandXML to efficiently link information between IFC as a standard model of BIM and CityGML as a standard model in the GIS sector and to prepare a basic fusion strategy and a method of utilization between BIM and GIS. The result of the study are as follow. Firstly, contents and structure of IFC, CityGML and LandXML are compared and analyzed. Secondly, the development direction of iBUM(Integrated Building and Urban Model) suggested, which is based on convergence technology for analysis of space information. Finally, a strategy and method of the BIM and GIS are proposed in the iBUM environment.

초기건축설계 지원을 위한 기류시뮬레이션 기술의 활용방안에 관한 연구
류정림(Ryu Jung-Rim),추승연(Choo Seung-Yeon) 대한건축학회 2011 대한건축학회논문집 Vol.27 No.4
The urban development weighted on development density has been focused not on the quality of urban environment but on the quantitative expansion of a city. Among the environmental problems from a lack of consideration for urban environment, the urban heat island phenomenon has become a vicious cycle due to the rapid urbanization and increasing exhaust heat. As a solution of this problem, Wind-Corridor is necessary to be discussed intensively. It is important to ensure the mobility of incoming cold fresh air into the inner city for the sake of a pleasant urban environment. When it comes to the urban planning, a building plans should be developed not to hinder the wind flow based on the urban climate characteristics by using GIS. In this study, a utilization of air flow simulation technology was suggested in initial stage of urban design to improve an urban climate-related environment through the activation of Wind-Corridor. The conclusions of this study are as follow: First, the air flow simulations were performed without the microclimate model by using geographic information systems (GIS) and WindNinja1.0. This regards as an useful method to evaluate air flow in the initial design stages. Second, a constant airflow simulation condition is built by limiting the type of terrain to flat land and wind speed input to a specific range. And the average air flow rate is derived by simulations with various factors such as slendernesses, spaces, and heights of the building. Finally, the smaller air flow rate should be considered in the initial design stage to maintain the wind passage of cold fresh air flowing into a city.

드론-BIM 기반 건축물 해체공사의 폐기물 발생량 평가
류정림 ( Ryu Jung Rim ),박원준 ( Park Won-jun ) 한국건축시공학회 2021 한국건축시공학회 학술발표대회 논문집 Vol.21 No.1
In order to respond to environmental problems and to efficiently recycle resources, it is important to evaluate the amount of construction waste generated. In particular, the estimation of the amount of waste generated in the demolition work was performed based on the basic unit of waste generated per floor area. This study proposes a method using drones as a method for evaluating the amount of demolition waste in a wide area. In the simulated application, the field measurement results and the proposed method were compared, and the effectiveness of the building volume calculation using drones was confirmed. It was confirmed that the building volume can be calculated quickly in the additional pilot application.
