본 연구의 목적은 GSIS를 이용하여 3차원 동영상 도로 시뮬레이션에 관한 연구이다. 이를 위하여 제주도 남부의 해안선 지역을 설정하여 3차원도로 설계를 실시하였다. 사용된 자료는 1/5,000수치지도와 현지측량자료를 사용하였고, 도로시뮬레이션은 소프트웨어 microstation CAD, Inroads를 이용하였다. 해안도로의 특성상 도로주변의 식재인 꽃과 나무 등을 삽입하여 경관을 고려한 3차원 도로가 이루어지도록 설계를 시도하였다. GSIS기술을 이용하여 설계된 도로는 3차원 시뮬레이션이 성공적으로 이루어 졌으며, 특히 도로의 전진주행 및 후진주행 등을 선택하여 산악도로의 경관을 평가할 수 있어 본 연구의 결과는 실제공사 시 해안도로경관 시뮬레이션에 적용할 수 있을 것으로 판단된다.

본 연구에서는 현장실험 실시의 제약을 극복하기 위해 3차원 가상현실(Virtual Reality)로 4차로 고속도로를 모델링한 후, 피실험자가 차량시뮬레이터(Driving Simulator)에 탑승하고 주행하면서 혼합곡선부의 선형변화에 대한 동적인 반응 데이터를 획득함과 동시에 도로 기하구조 이미지 인지특성 데이터를 획득하였다. 특히, 본 실험에 적용된 차량시뮬레이터의 그래픽 모듈은 동역학 해석 모듈로 얻은 데이터에 기초하여 운동재현기와 가상환경의 일치감을 최대로 하여 피실험자로 하여금 Simulator Sickness를 최소화하도록 하였으며, 감성요인으로 사용된 어의는 국어사전 및 전문가의 견해를 바탕으로 추출된 7개 항목의 형용사를 바탕으로 감성평가를 실시하였다. 또한 감성적인 측면에서 도로 선형과 안전성에 대한 인과관계를 규명하기 위하여 LISREL(Linear Structural Relationships) 모형을 이용하여 정적인 도로 안전성 모형과 동적인 도로 안전성 모형을 구축하여 복합선형구간에서 도로 기하구조의 변화에 따른 운전자들의 안전성에 영향을 미치는 요인을 규명하였다. 그 결과, 도로 설계시 운전자의 감성적인 측면을 고려한 도로 설계가 필요하며 이는 안전한 도로를 건설하는데 있어 매우 중요한 요인이며 이를 통하여 도로 안전성 향상에 기여할 수 있다고 생각된다.

This paper show that, without installation of expensive VR (Virtual Reality) program, the sharing information is possible through posting three-dimensional road structures on the web, and avoiding the conventional top-down decision making method, fast bottom-up communication is possible base on the Virtual GIS (Geographic Information System). In this paper, using Viewpoint Scene Builder, internet-based software, the transformation was conducted to give pertinent type for web posting. In order to use the completed route at the scene builder, the output with ASCII Export is required, and ASE (ASCII Scene Export) contains the property information including the coordinate and frame of mesh vertex. Through in advance recognition of the problems regarding route design and petition due to environmental rights infringement, the time and cost due to design alteration can be reduced. It's difficult to provide VR based on the internet because file that embodied with internet GIS was complicated and its capacity comes to scores of mega-bites. But, this study provides VR with internet according to a basis by simplification of files.

To meet the soaring demand recently, South Korea big shipbuilders are examining two things. One is new investment in plant and equipment. The other is replacement of production resources. Considering plant & equipment investment and replacement of production resources, even if actual production ability would be enough, the real output could be affected by limitation of logistics with lack of analysis. As we set up big shipyard in virtual space, we could perform actual production by using confirm production plan in virtual space. We've analyzed the load of block stock, load of road and load of transporter for logistics effects are followed by production increase. This research is to determine the possible problems of those analyzed results and to present the resolution using the current layout. And then modified yard layout, we reanalyzed previous three logistics effects. This simulation model could help administrator to make rational decision for changing yard layout.

Presently, research is hard to see design lot construction on actuality three-dimensional route although it applied three-dimensional techniques using constructed already two-dimensional plane design. Therefore, this research wishes to study about efficient decision-making at the public problem and design change that can happen during construction designing three-dimensional road and construction at actuality route location using VGIS.

What's the direction of INTERIOR ARCHITECTURAL DESIGN in 21 Century High Tech\ulcorner The purpose of this research is to show not only practical use of Computer Graphic(CG) as simple tool function, but offering conversation with computer and other ways of method. When we consider poor CG market, investment on the research of VR(Virtual Reality) is the most urgent. The investment on VR will solve various problems. Firstly. It will solve the problems drived from Interior design process by making spatial images like reality. Secondly, It will solve high wages and financial difficulties caused by raise cost funds. Thirdly, It prevents in a road from foreign company that will bring enormous program, caused by opening the domestic market. Also, It help interior designer check in advance the problems in constructure through showing him a supposed imagination including the system and location of equipments. But it is reality that even ordinary American can't offer VR(Virtual Reality) System. We should have noted that it is normal to spend 10 billion won for such presentation as Model House in the large corporation. We must acknowledge that it is such a waist of money nationally. Therefore, investment on CG & VR System is essential in order to save cost more effective presentation & interior design. We will see great result within a year. As we can see, there is huge area we have make develop. One of them is specific technical plan on VR System and study of flow chart. We close with simple methodological way to use VR System and will study Computer System. Which is fitting to CG that we have to solve the link of hardware and software on VR System\ulcorner We know from the cases in other countries that continuous research on this subject has great value for Interior Architectural Design and its effective use. When we try hard not only for methodological use but practical use, the purpose of CG and VR System will be a factor to contribute on this subject for better Interior design & presentation.

최근 표준으로 등록된 IFC(Industry Foundation Classes)4는 건축시설의 형상요소 표현에 한정될 뿐 도로, 교량 및 터널 등의 토목시설에 대한 형상표준을 정의하고 있지 않아 여전히 토목 형상모델의 교환을 위한 상호운용성에 제약이 있다. 특히 도로시설은 중심선형에 따라 모델링되는 선형적 특성을 가지며, 프로젝트 별로 형상이 서로 상이하여 표준화된 도로정보모델을 구축하는 것이 곤란하다. 따라서 본 연구에서는 도로의 형상정보모델 개발을 위해 3차원 설계 프로세스 관점에서 도로를 구성하는 구조요소 및 속성을 도출하는 것이 목적이다. 이를 위해 본 연구는 도로설계를 위해 활용되는 도로설계편람, 지침, 시방서 및 기하설계 기준 등의 정보를 분석하여 도로 구조물의 형상 요소와 속성을 추출한다. 도출된 형상은 엔티티(Entity) 항목으로 정의하고 가상 도로모델을 통해 정의된 도로 형상모델의 위계구조를 검토한다. 도출된 도로의 세부 구조 요소 및 속성은 인프라 분야의 BIM(Building Information Modeling)환경을 구축하기 위한 3차원 형상정보로 활용되며, 도로의 구체적인 형상, 타입 및 속성을 세분화하여 도로분야의 IFC로 확장하기 위한 기초자료로 활용될 것으로 기대된다.

In design stage of vehicles, the application of virtual durability analysis techniques enables us to cut down the necessary time and cost to carry out various physical experiments. In this study, computer simulations of vehicle suspensions were carried out with DADS program including component flexibility, and the durability analysis of vehicle components was executed with MSC/Fatigue program using the load history obtained from vehicle dynamic simulation. Driving test of a vehicle was also carried out to obtain precise input data for the durability analysis, and the results of virtual durability analysis were compared to those of experiments.

Highway have to be constructed under thorough investigation about function, economy, safety of the traffic and environment, because they are needing huge budget for construction and management as important facilities of the social overhead capital in the national economics. Initially the construction of roads becomes effective the plan, the design, construction phase. The design is foundation of accomplishment of the roads operation, the results of the design operation come to much effect a nation when using roads. Especially ancient design methods were not expected for visual effects as attaching weight to 2-dimensional drawing from flat. Therefore, it is difficult to recognize troubles happened during the work operation besides, many troubles are solved by modification of drawings as situations. For solving of those of the problems, it is emphasize on visual effect through introduction of 3-dimensional design from the initial phase. In case of national conditions, limited national land has caused increasing weight for construction of the roads through cities as the urban centered development. thereupon, citizens are increasing concern about the right of the light and the environmental effect, road designs and construction of the structures under agreement with local residents cause to make troubles. The analysis of 3-dimensional design is necessary as intermediation for decision making. In this study, Virtual reality techniques in 3-dimensional roads design are expected to visual effect on the publishing Internet Web, find problems in first phase and make decision between users and people having civil appeal.
