본 논문에서 제시한 Co-creation 플랫폼 소프트웨어 분석/설계 방법은 제품의 아이디어 단계부터 제품의 디자인 단계, 개발 및 생산, 마케팅 전 과정에 Co-creation 개념을 적용한 Co-creation 플랫폼 구축기술을 제공한다. 그리고 이 방법은 Co-creation 플랫폼 구축을 위한 자체 SNS 기능 및 OPEN API 를 통하여 기업의 클라우드 서비스와 기업 시스템과 연동하도록 설계 및 구현이 가능하도록 한다. 또한 아이디어의 수정 및 완성 단계에서 위키 기술을 적용하고 디자인 제작과정에서 스토리보드 프로토타이핑 협업 도구를 제공함으로써 고객 및 이해관계자가 디자인 작업에 적극적으로 참여하고 의견이 반영이 가능하도록 하는 기능 구현이 가능하다. 따라서 이것들의 설계 과정을 효과적으로 보여주기 위하여 Co-creation 분석/설계를 객체지향 분석방법에 의해 제시하고자 한다.

AMM(Additive Metal Manufacturing)이라 호칭되는 3차원 금속 프린팅(metal 3-D printing) 공정은 금속분말(metal powder)을 적층 재료로 사용하여 기계적부품용 실형상 금속 파트(metallic parts)를 직접 조형하여 제조한다. 한편, 조형 파트형상의 STL모델에 존재하는 기하학적 오류들과 특징형상들의 특이성으로 인하여 조형 작업 중에 내부에 결함들이 포함된 실형상 파트가 조형될 가능성이 존재하게 되며 이로 인해 3차원 금속 프린팅 조형공정 자체의 신뢰성에 문제를 야기할 수 있다. 본 논문에서는 이러한 조형작업 중 발생할 수 있는 결함들을 미리 진단, 분석하고 수정하기 위하여 첫째, 조형 전에 STL 형상모델의 진단분석을 통하여 결함요소를 사전에 탐지하고 둘째, 적층 단면내 조형 공구 경로상에 실제로 포함된 결함들을 분석하고 이를 수정하기 위한 조형 파트 진단 및 조형 공구 경로 검증 연구방법을 제시하였다. 또한 DED(direct energy deposition) 공정을 기준으로 2가지 STL 형상파트 사례들에 대하여 제시한 연구방법의 case study를 수행하였다.

PURPOSE. This study aimed to fabricate provisional crowns at varying build directions using the digital light processing (DLP)-based 3D printing and evaluate the marginal and internal fit of the provisional crowns using the silicone replica technique (SRT). MATERIALS AND METHODS. The prepared resin tooth was scanned and a single crown was designed using computer-aided design (CAD) software. Provisional crowns were printed using a DLP-based 3D printer at 6 directions (120°, 135°, 150°, 180°, 210°, 225°) with 10 crowns in each direction. In total, sixty crowns were printed. To measure the marginal and internal fit, a silicone replica was fabricated and the thickness of the silicone impression material was measured using a digital microscope. Sixteen reference points were set and divided into the following 4 groups: marginal gap (MG), cervical gap (CG), axial gap (AG), and occlusal gap (OG). The measurements were statistically analyzed using one-way ANOVA and Dunnett T3. RESULTS. MG, CG, and OG were significantly different by build angle groups (P<.05). The MG and CG were significantly larger in the 120° group than in other groups. OG was the smallest in the 150° and 180° and the largest in the 120° and 135° groups. CONCLUSION. The marginal and internal fit of the 3D-printed provisional crowns can vary depending on the build angle and the best fit was achieved with build angles of 150° and 180°.

In this paper, we suggest the system analysis method that links IDEF0 and conceptual analysis. Based on the method, we propose the implementation methodology that can be used to build CALS/EC systems in logistics industry. This paper presents data characteristic derived using ICAM DEFinition(IDEF0) and conceptual data modeling. Modeling methodology has been widely used for analysis and design of an enterprise information system. Further IDEF has been considered appropriate for developing functional and database models for the logistics environment.

Space Composition should be understood an aesthetic cognition about the basis of space in different points of view. It establishes the prescribed environment of space through the hypothesis of given geometrical object. Therefore, it makes understand the cause of space composition and conceive the consistency of various elements, orders, norms and forms of space composition, Through this study, the students may build up scenarios-form the beginning to the climax of space -, directions and full stories about the space.

Simulation is known to be a valuable tool for design and operation of Flexible Manufacturing Systems(FMSs) under study. However, in order for simulation to be useful, lots of knowledges about the behavior of system to be designed, statistics for output analysis, modeling techniques and a specific simulation language are required by the simulationist. In this paper a way to build simulation support system for nonexperts at simulation will be described and a simulation support system for FMS design and operation developed by the authors will be demonstrated.

The purpose of Computer Aided Design is to design good products as quickly as possible. To do this, it is important to reuse the old designs and build on them. Most engineering designers, therefore. hale studied methods for reusing old designs, and the results of their study hale been applied to new designs Unfortunately, this only involves reuse of geometric data without design knowledge. If they can design products with the geometric data, including design knowledge, of the old designed and share them through the Internet, design efficiency will be improved. In other words, one way to improve designer's productivity is to share design information that includes knowledge and scattered data across design offices. This paper introduces a shared design environment with distributed knowledge-base. A product design environment based on distributed knowledge-base is proposed, which integrates the CORBA, OLE and WWW as the network architecture, a 3D CAD system, and an expert system shell. A design example of the lens barrel of a projection television is implemented to verify the idea.
