My proposed Co-creation platform software analysis and design method in my paper, presents build technology of co-creation platform using Co-creation concepts refer to all process from products' idea level to products' design, manufacturing and marketing level. And this method can be possible to design and implement to be interlocked with company's cloud service and system through own SNS functions and OPEN API to build co-creation platform. Also owing to apply Wiki technology in the process of idea modification and completion level and provide cooperative work tools of story-board prototyping, it can be participate actively in the design process with customer and stakeholder together and realize functions to apply opinions. Therefore, Co-creation platform software analysis and design by objected-oriented analysis method is presented to show these design process effectively.

Metal 3D printing, which is an additive metal manufacturing (AMM) process, enables the development of full-density metallic tools and parts using metal powders that are precisely delivered and controlled for deposition with no powder bed. However, some unknown geometric defects and irregular geometric features on an STL model can possibly result in incorrect metal part fabrication after the build. This study first proposes a methodical approach for verifying the build part, including the missing facet problems in an STL model, by defining some irregular features that possibly exist on the part. Second, 2D tool paths on each build layer were investigated for detecting any singular region inside the layer. The method was implemented for building two sample STL models using a direct energy deposition process, and finally, it was visually simulated for diagnosis.

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.

Network security infrastructure is constantly developing based on the combination and blending of various types of devices. From the form of distributed control, the phased defense policy such as fire walls, virtual private communication network, invasion prevention system, invasion detection system, corporate security management, and TSM (Telebiometrics System Mechanism), now it consolidates security devices and solutions to be developed to the step of concentration and artificial intelligence. Therefore, this article suggests network security infrastructure design types concentrating security devices and solutions as platform types and provides network security infrastructure design selecting methodology, the foundational data to standardize platform design according to each situation so as to propose methodology that can realize and build the design which is readily applied and realized in the field and also can minimize the problems by controlling the interferences from invasion.

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.

The Purpose of this study is to analyze the green design strategies in residential building, based on case study of Solar Decathlon in USA. This study could provide the basic reference data and theocratical foundation for finding new green design strategies and applicability of green design for korea. The Solar Decathlon is an green design competition that challenges collegiate teams to design, build, and operate the green residential building with optimal energy production and maximum efficiency. As a result of the analysis of this study, the green design strategy is identified and analyzed design issues related in energy, materials, and indoor/outdoor environment. Also, it is useful to find best green design strategy with more economical and environmental benefits presented by renewable energy and design solutions. This study is based on selected 18 green housings of Solar Decathlon from 2002 to 2013. This result is helpful to understand the green design strategies for green residential building's design of modern residential building, and expect future green residential building design approach.
