Multidisciplinary Design Optimization (MDO) is an optimization technique considering simultaneously multiple disciplines such as dynamics, mechanics, structural analysis, thermal and fluid analysis and electromagnetic analysis. A software system enabling multidisciplinary design optimization is called MDO framework. An MDO framework provides an integrated and automated design environment that increases product quality and reliability, and decreases design cycle time and cost. The MDO framework also works as a common collaborative workspace for design experts on multiple disciplines. In this paper, we present the architecture for an MDO framework along with the requirement analysis for the framework. The requirement analysis has been performed through interviews of design experts in industry and thus we claim that it reflects the real needs in industry. The requirements include integrated design environment, friendly user interface, highly extensible open architecture, distributed design environment, application program interface, and efficient data management to handle massive design data. The resultant MDO framework is datasever-oriented and designed around a centralized data server for extensible and effective data exchange in a distributed design environment among multiple design tools and software.

As computer performance and needs of user convenience increase, computer user interface are also changing. This changes had great effects on software development environment. In past, text editors like vi or emacs on UNIX OS were the main development environment. These editors are very strong to edit source code, but difficult and not intuitive compared to GUI(Graphical User Interface) based environment and were used by only some experts. Moreover, the trends of software development environment was changed from command line to GUI environment and GUI Editor provides usability and efficiency. As a result, the usage of text based editor had decreased. However, because GUI based editor use a lot of computer resources, computer performance and efficiency are decreasing. The more contents are, the more time to verify and display the contents it takes. In this paper, we provide a new parser that provide multi view editing, incremental parsing and multiple entry of abstract syntax tree.

This paper presents the development of a racing game by controlling multiple smartphones based on ad hoc communication. The proposed racing game by the smartphone-based control interface does not require any specific game console or remote controller. Thus, any multiple users who have smartphones are able to play the game in a monitor at the same time. In addition, the developed game is applicable to actual mobile robots in cases where the positions of all robots are measured, since its game unit is a mobile robot model with a differential drive. An experimental result shows that the racing game in a PC can be realized by the proposed communication interface through four iPhones based on acceleration sensors.

This paper describes the development of general purpose operator interface which uses a color graphics terminal with a touch-sensitive screen as the control console. Operators interact with a process through a collection of application-dependent displays generated interactively by users familiar with the physical process. The use of real-time operating system(iRMX-86) and multitasking results in a straightforward and reliable development which may easily be extended to support multiple devices of varying types in the control console.

Digital media changed not only our lifestyle and sense of value but also art and space design, and development of technology will accelerate the alteration. It provided limitless possibility and inspiration to art, architecture and design. In this 'image' era, media communicate with us mostly in visual method, which gets to he realized by visual interface. The purpose of this study is to analyze the tendency of visual interface of contemporary interior design cases in the standpoint of digital media characteristics and suggest directions for future space design. The characteristics of digital media and interface are defined, and how the concept unfolded in art, design is also discussed. In interior design, the concepts come out as various types of visual interface, showing the characteristics of composition of material and immaterial, interaction between visual information and space users and among users, realization of cyberspace and simultaneous coexistence of multiple space-time multi-layer.

본 논문에서는 유무선 통합 환경의 차세대 방통융합 서비스를 위한 기반 기술로서 다양한 액세스 망에 대한 다중 접속 인터페이스를 갖는 멀티모드 단말의 인터페이스 가상화 기법을 소개한다. 제안된 가상 인터페이스 기술은 멀티모드 단말의 각 물리 인터페이스에 대해 상이한 IP 주소를 할당하고 패킷 전달 시 이들 주소간의 변환을 수행하는 기존의 방식과 달리, 고정된 하나의 단일 IP 주소 만을 이용하여 다수의 물리 인터페이스들을 가상화하는 기능을 제공한다. 따라서 패킷 전달 시 IP 주소 변환 등 단말 기능 변경을 요구하지 않으므로 Proxy MIP와 같은 네트워크 기반 IP 이동성 제어 기술과 연계하여 적용하기에 용이한 장점을 제공한다. 또한 기존의 OS가 단일 단말 내의 상이한 물리 인터페이스에 대해 동일 IP 주소를 할당할 수 없도록 하는 제약사항을 극복함으로써 MBB(Make-Before-Break) 방식의 핸드오버 제어뿐만 아니라 BBM(Break-Before-Make), 다중 접속(Multi-connection) 등과 같은 다양한 방식을 모두 지원할 수 있는 장점을 갖는다. 제안된 가상 인터페이스는 네트워크장치 인터페이스 표준 규격으로 개발된 NDIS 라이브러리를 이용하여 구현되었으며, 테스트베드 구축과 시험 프로그램 개발을 통해 주요 기능의 시험 및 동작 결과를 확인할 수 있었다. 이러한 가상 인터페이스를 통해 멀티모드 단말이 이종 액세스 망간 핸드오버를 수행하는 도중에도 동일한 IP 주소를 이용하여 실시간 멀티미디어 서비스 세션을 끊김없이 유지하도록 지원하는 것이 가능하다.

본 논문은 교통 신호 제어 알고리즘들의 성능을 비교하기 위한 복합교차로 시뮬레이터를 구현하였다. 기존의 교통 시뮬레이터들은 단일교차로를 대상으로 하거나 텍스트 모드로 동작하는 경우가 많았다. 논문의 시뮬레이터는 Visual C++의 MFC 라이브러리를 사용하여 n $\times$ n 형태를 갖는 복합교차로에 적합하도록 객체지향적으로 구현되었으며, 성능 비교를 위하여 제어 알고리즘들을 별개의 윈도우에서 처리하기 쉽도록 MDI 방식을 사용하였다. 개발한 시뮬레이터는 그래프 윈도우와 맵 윈도우의 편리한 사용자 인터페이스, 논리시간 설정을 통한 다목적 시뮬레이션, 다양한 성능평가 출력 등의 특징을 갖는다. Abstract In this paper, we implemented a multiple crossroad simulator to evaluate the performance of the traffic signal control algorithms. Most of existing traffic simulators were operated in text-mode or at a single intersection. We developed the object-oriented simulator suitable for multiple crossroads with n $\times$ n intersections by using MFC (Microsoft Foundation Class) library in Visual C++. The simulator was implemented by using MDI (Multiple Document Interface) scheme in order to process both control algorithms in separate windows respectively. Our simulator has the following features: user friendly interface with graph window and map window, multi-purpose simulations by setting logical time, and various forms of performance evaluation.

The purpose of this paper is to present a model to design the layout of the user interface components that handles many numbers of qualitative factors. An alternate rating system is also proposed for the closeness relationship ratings between the various pairs of components evaluated by using GOMS (goals, operators, methods and selection rules) technique. The proposed model is applied to the design of the part of the user interface in order to obtain the best layout of the components. The results of the proposed model are compared with that of an existing model, which handles single qualitative factor applied to obtain the layouts of user interface components.
