In this paper we implemented 3D contents based work process simulation for 3D view contents. For this the method of 3D view technique is explained. The automobiles and PC assembly processes according to the virtual scenario showed the technique which assists workers through 3D view. Also for 3D information visualization, max script of contents modeling functions using 3D MAX was developed. The functions are designed to customize coordinate, material edit on modeling, rendering, and 3D object files with max script.

Recently, the importance of the construction technology of the free-formed buildings is becoming more significant, as the interest and demand for the free-formed buildings are increasing. However, it takes much time and cost during the construction of free-formed buildings because the current construction technique of freeform concrete segments is manufactured by a formwork. Therefore, in this study, we suggested a new manufacturing process based on the LOM-type 3D printer for freeform concrete segments that can shorten construction time and reduce cost when constructing freeform concrete segments, and we also verified the feasibility of production process through mock-up test. The result shows that the suggested process shortened 47.8% of production time and saved 56.2% of cost compared to the existing steel formwork method. In conclusion, it is expected that the production method of freeform concrete segments using 3D printer will contribute to the improvement of productivity of freeform concrete segments construction and the activation of new construction method for free-formed building construction.

In this paper, the business process was easily modeled by distinguishing between the business process and work logic. Based on this model, B2Bi collaboration Workflow modeling tool, which facilitates collaboration, was designed and implemented. The collaboration workflow modeling tool consists of 3 components; business process modeling tool, execution engine and monitoring tool. First, a business process modeling tool is used to build a process map that reflects the business logic of an application in a quick and accurate manner. Second an execution engine provides a real-time execution environment for business process instance. Third, a monitoring tool provides a real-time monitoring function for the business process that is in operation at the time. In addition to this, it supports flexibility and expandability based on XML and J2EE for the linkage with the legacy system that was used previously, and suggests a solution for a new corporate strategy and operation.

Nowadays the widely used media in architecture include visualizations, animations and three-dimensional models. 3D digital methods using active CAM(Computer Aided Manufacturing) and CNC(Computerized Numerical Control) imaging have been developed for accurate shape and 3D measurements in freeform buildings. In contrast to a conventional building using auto CAD system and others, the proposed digital optimization method is based on a combination of 3D numerical data and parametric 3D model for design and construction. The objective of this paper is therefore to present digital optimization process for constructability of freeform building. The method can be useful in the effective implementation of an error-proofing process of freeform building during design and construction phase. 3D digital coordinate data can be used effectively to identify correct size of structural and finish members and installation location of each members in construction field. In addition, architects, engineers and contractors can evaluate design, materials, constructability and identify error-proofing opportunities. Other project participants can also include representatives from all levels of management, departments as well as workers and key subcontractors' personnel, if necessary. The 3D digital optimization process is therefore appropriate to serious variations in freeform shape. For future study, the developed digital optimization method is necessary to be carried out to verify the robustness and accuracy for constructability in construction field.

In construction sites, policies are changing considering the convergence of 3D scanning and BIM. In order to respond to this, it is urgent to develop guidelines for systematic collaboration methods that take into account the perspectives of practitioners. By participating in the delivery process using 3D scanning technology, tasks such as ordering, field scanning are defined in terms of mutual communications. Also, the collaboration process is about communications between off-site and on-site, such as feed-back using data and documents. In the future, we will propose guidelines based on such collaborative process models.

Industrial design development methods and processes have changed in accordance with Industrial Information Age. These days, problems are created by existing methods and evaluation of design value , all problems concerned with time and finances sitaution have been made a subject of discussion. Development of design processes have been changed by the development of problem recognition and solving tools, and dpsign tpchnulugy havp hppn replaced by computer technology,Thus. software design processes linking thoughtware to hardware are used in the solution of design problems with many parts. In this study, 3D Modeling samples are presented, 3D Modeling can realise ' Ideas' to '3Dimentional Virtual Ohjects'. These effect and value are anle to decisively influence the process of design problem conference-ebealuation-solution.Proxesses of actual modeling and rendering are made as follows. By compusition of simple 20 drawings and shaping them into 30 objects, 30 solid models can be made. To prssent effectivley, we can make a sample model by varying camera views,light sourses,materials and colours etc. This sample is evaluated by various cumposition, methods and PERT(Program Evaluation and Review Technique). This cuncrete sample (tentative plan)is changed within the CAD SYSTEM by design evaluation, and then converted to flowchart of mass productive conception through refined data. So, that tentative plan can be conformed to design desire actuillly, to the utmost degree. Finally, this design process can be proposed as il new method in cuntrast with current methods. The aim of this study is to suggest effective evaluation methods of design outcome among many evaluating elements.

국내 정부부처 및 지역자치단체에서 수행하고 있는 연구개발 프로젝트의 선정과 평가에 관한 연구는 광범위하게 이루어지고 있다. 그러나 각 정부 부처별로 실시하는 평가프로세스와 지표의 경우 부처별 특성과, 과제의 특성을 반영하기 위한 프로세스와 지표를 개별적으로 보유하고 있으나, 과제의 평가를 수행하는 조직의 규모나 지역적 특색을 반영하기 어렵다.본 연구는 C 지역의 테크노파크(TechnoPark) 사업자가 수행하는 지역 자치단체 중심 R&D 프로젝트의 특성과 지역적인 특색을 반영한 평가관리 시스템을 개발하고자 한다. 본 연구에서는 먼저 국내 출연연구기관 및 정부부처에서 수행하는 평가시스템의 특성을 파악하고, 각 기관에서의 평가프로세스와 평가지표들을 조사하여 공통적/개별적 특성을 분류하였다. 분류된 프로세스와 지표들과 C 지역의 지역/산업적 특색을 분석하고 C 지역에서 수행한 3년간의 모든 과제에 대한 분석을 수행하여 지역적인 특색을 반영한 평가프로세스와 지표를 도출하였다. 또한 연구개발 프로젝트의 선정평가를 위한 사전 기술성 평가를 위한 기술가치평가와, 프로젝트의 수행결과 이후 나타나는 부가적인 효과를 분석하기 위하여, 프로젝트단위의 균형성과지표를 적용하여 프로젝트의 사후/추적관리 방안을 제시하고자 한다.

In the 21th century, audiences were fascinated with stereoscopic 3d in the theaters again. Since 2009, interest in stereoscopic 3D had been increased explosively, but shortfall in stereoscopic 3D contents is yet to be solved. However, despite shaky conditions in broadcasting businesses, stereoscopic 3D movies are released steadily in Hollywood. And the movies with strong storytelling are performing in the film market, so common point among them is that stereoscopic 3d techniques are used for subserving narrative immersion effectively. Therefore, stereoscopic 3D techniques will be helpful for enhancing narrative immersion. So I researched relations between immersion and stereoscopic 3D, and proposed space planning process for enhancing narrative immersion in stereoscopic 3D.
