전 세계적으로 급속한 도시화로 인하여 각종 사회문제와 부작용 등이 발생하고 있다. 이에 따라 시민의 삶의 질을 향상시키고 지속가능한 도시개발을 위하여 스마트시티 조성이 추진되고 있다. 국내에서도 각 부처별로 스마트시티 조성을 위한 비전 및 전략 등이 제시되어 왔으나, 부처별 입장에서 제시되는 한계점을 보이고 있으며, 국가적인 차원에서의 스마트시티 조성을 위한 비전과 핵심전략이 설정될 필요가 있다. 따라서 본 연구에서는 국내 스마트시티의 현황 분석과 문제점 분석을 통하여 스마트시티 조성을 위한 비전을 설정하였다. 또한 국내외 스마트시티 현황 분석 및 문헌고찰을 통하여 STEEP 분석을 실시하고, 이를 기반으로 인과지도를 작성하여, 스마트시티 비전 달성을 위한 주요전략들을 도출하였다. 본 연구에서 제안한 스마트시티 비전 및 주요전략들은 성공적인 스마트시티 조성을 위한 방향 설정에 기여할 수 있을 것이다. Due to rapid urbanization around the world, various social problems and side effects are occurring. Accordingly, the creation of smart city is being promoted to improve the quality of life of citizens and promote sustainable urban development. In Korea, visions and strategies for the creation of smart city have been presented for each ministry within the government. But they are proposed from the standpoint of each ministry, not from the national level. Therefore, it is necessary to establish a vision and core strategies at the national level. In this study, the problems of Korea smart city were derived, and a smart city vision was established as a solution. In addition, STEEP analysis was conducted through Korea and overseas smart city status analysis and literature review, and based on this, CLDs (Causal Loop Diagrams) were drawn up to derive major smart city strategies. The smart city vision and major strategies proposed in this study are expected to be helpful in setting the direction for future successful smart city creation.

Recently, the smart city market based on the 4th industrial revolution is rapidly expanding worldwide and is being promoted in various ways. Korea has promoted various smart city public and private partnership projects, but there were limits to the activation of smart city public and private partnership projects due to insufficient enactment and revision of laws, public-oriented ordering method, and lack of private execution capacity. Therefore, this study intends to suggest key success factors for each stage of smart city public and private partnership projects through the analysis of the order status of the smart city national pilot city and the analysis of previous research. Through this, it is expected that it will be possible to eliminate various types of risks that may occur in the domestic smart city public and private partnership projects and contribute to revitalizing the smart city public and private partnership projects.

BIM기반 VR을 활용한 VE 대안 적용가능성 검토 프로세스

VE is one of the technologies that are essential to promote cost reduction and performance improvement in construction projects. In the VE process, there are very important steps in deciding whether to adopt VE ideas and alternatives or not. However, when examining the possibility of selecting and adopting alternatives, it is difficult to clarify the differences and characteristics of the existing and improved proposals due to lack of understanding of the owner and inadequate consideration of harmonization with the alternative surroundings. In order to overcome these problems, it is necessary to effectively exchange information related to alternatives among VE participants and to examine the applicability of VE alternatives more in-depth. Therefore, in this study, a process for reviewing the applicability of VE Alternatives using BIM based VR was proposed to review more appropriate VE alternatives.

BIM 기반 VR을 활용한 VE 대안 적용가능성 검토방안
쿠훌룩(Khulug Ikhbayar),김승권(Chengquan Jin),현창택(Changtaek Hyun),이상훈(Sanghoon Lee) (사)한국CDE학회 2022 한국CDE학회 논문집 Vol.27 No.2
VE is one of the most effective technologies to increase the value of construction projects. In the VE process, the VE team decides whether to select and adopt the VE alternative through the process of reviewing its applicability with the decision-maker, the client, and the original design team. In this important process, there are difficulties such as reviewing floorplan information, material, quality information, and clash detection. In addition, communication and information delivery between VE participants is inefficient due to several reasons such as lack of owner’s understanding regarding the VE alternative and insufficient consideration of harmony between the alternative and it’s surrounding. In order to improve this, there is a need for improvement in reviewing the applicability of VE alternatives while effectively exchanging its related information among VE participants. Thus, in this study, the problem of applicability review of VE alternatives was derived through the analysis of prior research. Accordingly, the reasons for rejecting other VE alternatives were identified, suggesting an improvement in reviewing the applicability of VE alternatives using BIM-based VR.

웹 서비스를 고려한 스마트시티 디지털 트윈 모델 경량화 및 시스템 구축방안

Recently, it has been getting an increasing attention to develop a digital twin system that can provide spatial information and services of a smart city through a Web service, and building a digital twin system with IFC-CityGML integrated data has been the most desirable approach. However, due to the heavy computing load and technical difficulties to process the IFC-CityGML integrated data, such a system is not appropriate to provide various smart city services to the unspecified public as a Web service. To address the issue, the study proposes a method that uses a lightweight 3D object model and a game engine. The method is able to not only develop a Web-based digital twin system efficiently, but also run physical simulations by using the game engine, the reality level of which is difficult to achieve with a common web 3D visualization engine. The effectiveness of the proposed method has been verified through a case study of fire emergency management that implements a digital twin system in LOD 3.5 and simulates the shortest evacuation route.
