본 논문은 멀티패러다임 프로그래밍을 이용한 효과적인 문제 해결 방식을 보이고 멀티패러다임 사고를 적용한 소프트웨어 설계의 실용적 타당성을 예시하기 위하여 3D 모델링 분야를 위한 멀티패러다임 DSEL을 설계한다. 먼저 3D 모델링 응용에 필요한 프로그래밍 요소를 문제의 특성을 고려하여 패러다임 영역별로 분할하고, 이에 따라 분할된 요소를 대응하는 단일 패러다임을 이용해 설계한다. 마지막으로 단일한 패러다임을 이용해 설계된 각 기능을 통합하고 보완하여 멀티패러다임의 협력 효과를 극대화한다.

There is little study related to the 3D convergence contents authoring tool for teacher. In this study, we purposed the design of the interactive 3D convergence contents authoring tool for a teacher. To draw the design, firstly, we investigated the authoring environment of teachers and interviewed teachers. Based on this investigations, we proposed the functional requirement and UI/UX(User Interface/User Experience) design of it. And we investigated the level of focusing group satisfication with the UI/UX design. Based on these results, we will implement the authoring tool.

In this paper, we propose a 3D view design scheme which arranges 2D information in a 3D virtual space with a flexible interface and voice information. The scheme allows the user interface of the 2D image in 3D virtual space anytime from any view point. Voice information can be easily attached. It is this simple and efficient image and voice information arrangement in 3D virtual space that improves information transfer.

There wasn't very successful practice cases for the quantity take-off based on the CAD system since the CAD system is used in the construction industry more than 20 years in Korea. It was also not easy to use 3D CAD system in design management and cost management in the construction industry although 3D CAD system is very successful in the manufacturing industry for those areas recently. It is important to construct 3D libraries and to supply those libraries for the designers in time. Architectural work is a kind of creative work. So, Architects like to create their own model. Unlike the manufacturing industry, 3D CAD system can not be survived in the construction industry without new 3D objects supply in the right time. Moreover, the estimation system for 3D must support the schematic design phase, detailed design phase and construction design phase. The product called "Constructor" of Graphisoft consist of modeller, estimator and scheduler based on 3D model. We applied the system to a real project and compared the estimation result and we made a very successful case study.

Recently, work-related musculoskeletal disorders (WMSDs) become a hot issue in the industrial fields. To prevent the potential risk of workers, various approaches have been adopted. One of the approaches is to improve the design of product, that of jig (or fixture) and that of workstation in the early stage of the development. 3D simulation technology is known as the powerful method for detecting such problems before constructing the workstation, because it is possible to evaluate the posture of worker using 3D models in a cyber space. It enables to find the unexpected problems and save the time and cost for redesign and rework. This paper introduces a 3D simulation case study of workers in an excavator factory. 3D models of products, jigs were developed with CATIA. The assembly processes were animated in IGRIP and DPM. Finally the various postures of worker were simulated using Human. As a result, some postures were analysed as the risky jobs and the result of simulation was used to improve the system.

Hull design data is currently prepared by a 2D CAD system and re-input to 3D CAD systems specialized for detail design or to a structural analysis system. In this paper, sharing design data among different CAD systems has been studied. Based on STEP methodology, a neutral model is generated from 2D AutoCAD drawings. To handle a geometric data of this model, the non-manifold model of ACIS is used because it can support various CAD data representation such as 2D graphic entities, 3D wireframe, 3D surface model, and solid B-Rep/CSG model. It is observed that a mon-manifold model can easily be transformed to a 3-D wireframe model for the hull detail design system AutoDef or a FE model for the structural analysis system Nastran.

This study aims to suggest the improved business process by analyzing the current design process on work flow of the 3D design of power plant, drawing a problems and setting the improving direction through the integration method of the business process reengineering(BPR). In order to realize the improved business process, the integrated design performance system focused on the 3D design was established and accordingly the study analyzed cases of project performances through the integration system and drew the improved effects quantitatively. In the result of the project performance applied with the 3D design integration system, it showed 20.4% design cost saving effect for appropriate rated cost and the integration of design information from each design parts, sub contracters and vendors reduced overlapped works and improved the consistency of repeated design alteration.

In this paper, a diplexer circuit to separate GSM/CDMA band is designed using a LTCC (Low Temperature Cofired Ceramic) multi-layer technology. In order to increase a integration capability of the diplexer, it is designed in 6-layer LTCC sunstrate with a elative dielectric constant of 7.2 using 3-dimensional (3-D) multi-layer inductors and capacitors. The size of the designed diplexer including CB-CPW pads is $3,450{\times}4,000{\times}600{\mu}m^3$. An insertion loss (IL) and return loss of GSM band are less than -0.23dB and -10dB, respectively. In the case of CDMA band, the IL of -0.53dB and RL of below -10dB are archieved.
