This study researches the effectiveness of virtual experiences as an evaluation method in design. For the study, I researched the result on the spatial recognition before, abstracted visual objects and factors in recognition process and made up 43 inquiries for the evaluation through the experts group. Besides, set the analytical code between recognition factor and spatial constituents, made analysis the result from it. From April 1st to June 30th in 2004, the virtual model of educational place, college main building and city library was established as a subject of the research and studied the result. The methods that are used for the study are frequent analysis, T-test, reliability analysis, factor analysis etc. and SPSSWIN Package is used for the statistic analysis. There were two times of analysis on the evaluation to analyze the effect of virtual models on the web basis, one group evaluated the virtual building same as real and the other group evaluated the building site. Then analyzed the differences and correlation between the two. In result, college building, the first subject of study, and the second city library shows that made little differences between on the spot evaluation and virtual evaluation. Therefore, it is considered that the design evaluation with virtual model on the web basis has a vantage. But some problems founded that solved between preceding and present research through the feedback. It is as follows, 1. detection of problems that insufficience validity in the first survey. 2. found some not-validity inquiries. 3. detection of necessities that qualitative improvement and technical repletion in virtual environment.

Purpose: This study aims to measure how information quality, system quality, security, usefulness, and ease of use of Augmented Reality (VR) and Virtual Reality (AR) influence user satisfaction, motivating intelligent travel technology developers to improve VR/AR quality to meet customer requirements. Research design, data and methodology: This study investigates users interested in travelling in Ho Chi Minh City and Nha Trang City, Vietnam. The research model was implemented using an online questionnaire and face-to-face from 405 valid samples. To evaluate the scale's reliability, the study used the software SPSS 20. Test research hypotheses and evaluate measurement and structural models. This research uses AMOS 20 software. The proposed model is firmly grounded in the Information System Success model (ISS) and the Technology Acceptance Model (TAM), providing a solid theoretical foundation for our research. Results: Results show that consumer perceptions of information quality, system quality, security, usefulness, and ease of use have a positive impact on the perceived quality of VR/AR, thereby influencing tourists' travel intention. Conclusions: The results of this research enrich the theoretical understanding of consumer behaviour toward intelligent technology products in tourism, providing management implications for manufacturers to improve the quality of tourism products and satisfy user requirements in experience before considering choosing a destination.

디지털시대의 일환으로 현실세계를 가상으로 정확하게 옮겨서 현실에서 할 수 없는 어떤 고가의 장비 수명을 저하시키는 스트레스 테스트를 실시하여 제품의 취약부분을 시뮬레이션 하는 디지털 트윈이 제조업에서 활발히 사용되고 있다. IoT의 발전으로 인해 현실세계에서 수집되는 데이터를 정확하게 수집하여 가상의 공간에 동일하게 만드는 디지털 트윈은 교통, 재난, 주거, 방역, 에너지, 환경, 고령화 같은 도시 생활의 문제에 대한 정확한 예측을 할 수 있기 때문에 스마트 시티 건설에 필요한 도구로 자리매김하고 있다. 디지털 트윈은 제조업분야에 적용이 많이 되고 있지만 본 연구에서는 스마트 시티에 적용하여 4차산업혁명시대에 걸 맞는 스마트 시티 모델을 제안하고 제안된 모델을 통한 시민의 안전, 복지와 편리성을 증가시켜 기술의 발전이 삶의 질을 향상시키는 데 기여하고 한다. 또한, 디지털 트윈을 스마트 시티에 적용할 경우 실시간 상호작용을 통하여 현실성과 즉시성을 유지함으로써 현실과 가상간의 실시간 동기화를 통화여 보다 정확한 예측 및 분석을 할 수 있을 것으로 기대한다.

본 연구는 다양한 형상과 정보를 가질 뿐만 아니라 신축 및 재건축을 통하여 끊임없이 갱신되는 건물에 대해 3-D GIS를 구축하기 위한 기초자료를 효율적으로 획득하고 관리하기 위한 방법을 제시한다. 먼저 건물정보모델(BIM)과 지리정보시스템(GIS)의 정보모델의 특징들을 비교해 보고, 가상도시 구축을 위한 정보모델인 CityGML과 건물표현을 위한 세밀도를 살펴본 다음, BIM으로부터 CityGML에 따른 건물정보를 추출하기 위한 프로토타입을 구현하여 실행사례를 보인다. 본 연구의 접근방법은 건축설계 및 건축관련 엔지니어링 사무소, 또는 건설회사에서 CAD로 작성한 기존의 건물 및 부지에 관련한 2, 3차원 정보뿐만 아니라 새로운 추세로 자리잡는 IFC 정보를 활용할 수 있어 국가 지리정보시스템내에 건물 외형과 내부 모델을 구축하기 위한 많은 노력을 절감할 수 있다는 장점이 있다.

This study aims to propose a smart city governance logic model that can accommodate more diverse information service systems by mixing hub-and-spoke and blockchain technologies as a data management model. Specifically, the research focuses on deriving the logic of an operating system that can work across smart city planning based on the two data governance technologies. The first step of the logic is the generation and collection of information, which is first divided into information that requires information protection and information that can be shared with the public, and the information that requires privacy is blockchainized, and the shared information is integrated and aggregated in a data hub. The next step is the processing and use of the information, which can actively use the blockchain technology, but for the information that can be shared other than the protected information, the governance logic is built in parallel with the hub-and-spoke type. Next is the logic of the distribution stage, where the key is to establish a service contact point between service providers and beneficiaries. Also, This study proposes the establishment of a one-to-one data exchange relationship between information providers, information consumers, and information processors. Finally, in order to expand and promote citizen participation opportunities through a reasonable compensation system in the operation of smart cities, we developed virtual currency as a local currency and designed an open operation logic of local virtual currency that can operate in the compensation dimension of information.

In this study, a Virtual geological Field Trip(VFT) learning program using 3D panorama virtual reality techniques was developed to learn about the Gongju city 7 area located in Chungcheongnam-do, Korea. The developed $360^{\circ}$ 3D VFT program can show every face of observational points and interact as zoom-in, zoom-out and image rotation. For the educational effects of the materials, it is provided with a compass, a protractor, enlarged images, pop-up windows, etc.. The program was applied to the class of 35 gifted students in middle school to investigate the effectiveness of the program. The results showed that positive responses of the students were 90% or more. When geological field trip problems like cost, safety, distance occur in geological learning procedure of middle school science, this VFT program can become as a supplementary learning material and a solution.
