Since the importance of eco-friendly architecture is rapidly increasing, BIM receives significant attention as an alternative that would derive the practical results and apply the design values of eco-friendly design elements to the architectural design process. Therefore, this study establishes an Integrated Design System based on Green BIM by applying the eco-friendly design values logically and systemically. The study also proposes practical case studies to examine the possibility of application. As a result, the framework of Green based Integrated Design System(gbIDS) and a prototype of Web-based gbIDS were developed to improve the working environment of small architectural firms.

최근 대한 약사회에서 오래된 약물의 섭취로 인한 부작용을 예방하고 약물에 의한 환경오염을 예방하자는 내용으로 공공 광고를 하고 있다. 또한 의약분업으로 인한 약물 남용을 예방하고자 하였으나, 약물 처방의 복잡한 절차와 약물처방 비용만 증가시켰다. 현 상황을 벗어나기 위한 좀더 효율적인 시스템의 도입이 필요하게 되었다. 유비쿼터스와 융합 기술이 IT 분야의 트랜드가 되었으며, 이러한 기술을 이용한 약물 남용 및 관리를 위한 모바일 기반 의약품 정보시스템과 약품 이미지 검색의 프로토타입을 설계하고자 한다.

Launched in 1999 and funded by the Korean government, the R&D project of developing the. light train system technology is finally wrapped up to produce its prototype train prototype and all the research activities on signal, communication, power supply third rail Type and infra-structure have been completed. In an attempt to verify the usability of the system through an actual testing and as a preliminary step to the application of the system to overall light train construction projects to be implemented in different cities in Korea, testing lines are under construction now. Here we'd like to introduce people to the general overview of the test line construction and interface found in the process of project.

In this paper, analysis, design, control and prototype construction of a wearable wire-driven haptic interface called HapticPen is discussed. This device can be considered as a wire driven parallel mechanism which three wires are attached to a pen-tip. Wire tensions are provided utilizing three DC servo motors which are attached to a solid frame on the user's body. This device is designed as input as well as output device for a wearable PC. User can write letters or figures on a virtual plate in space. Pen-tip trajectory in space is calculated using motor encoders and force feedback resulting from contact between pen and virtual plate is provided for constraining the pen-tip motion onto the virtual plane that can be easily setup by arbitrary non-collinear three points in space. In this paper kinematic model, workspace analysis, application analysis, control and prototype construction of this device are presented. Preliminary experiments on handwriting in space show feasibility of the proposed device in wearable environments.

The shaped charge consists of the cast or pressed explosive and the metal liner. The pressure formed in detonation wave is so high that the liner is collapsed and the jet of high temperature, pressure and velocity is produced. The jet penetrates the target. In this paper, the simulation for optimization of flexible linear shaped charge(FLSC) was carried out by AUTODYNE program. Based on the results of simulation, we made a prototype of FLSC and evaluated penetration performance, flexibility and its application. The test result of prototype was compared with that of simulation.

In order to apply into a compact and reliable centrifugal blood pump, this paper introduces a self-bearing motor in which a rotor is rotated without contact. The rotor is actively controlled in only radial directions, while the axial and tilting motions are passively stable owing to the disk-shape structure of the rotor. A prototype was made in outer-rotor type that is far better in the compactness than inner-rotor type. The prototype could be driven up to 8000 rpm with the rotor vibration under 0.12mm. The maximum cardiac output and pressure head were 9 L/min and over 200 mmHg, respectively. These experimental results show that the proposed self-bearing motor has sufficient performance for application to a real blood pump.

This paper deals with the design and the characteristic analysis of a coreless axial flux permanent magnet (AFPM) motor. Because a direct-drive wheel motor is easily derived from it, the AFPM motor is very suitable for application in an electric scooter. Compared to a conventional motor of the same size and weight, the AFPM motor is proven to have more power and torque per unit weight. In this paper, an AFPM coreless motor with a double-sided rotor disk equipped with Nd-Fe-B rare earth magnets is designed and a prototype of the motor is manufactured, which will be properly applied for the low-speed, and high-torque direct drive required for the electric scooter. The manufactured prototype of the motor has a rating of 300W, 510rpm, 5.6Nm, and 85% efficiency.

In the recent manufacturing industry almost all sorts of activities tends to be digitized and networked to enhance the comprehensive efficiency of the enterprise. In that sense, enterprise informatization system as well as product information sharing system plays an important role, and those application systems are to be integrated in a smooth manner. In this paper, a prototype of an web-based product information sharing system is developed, which integrates information on technical documentation and parts information together. The prototype also integrates information on the implementation strategies for the enterprise informatization.

This paper describes the development of a prototype expert system, which is designed to analyze loom production efficiency by employing a loom monitoring system. The problem field of the prototype expert system is the loom failure analysis which has a great effect on prouction efficiency, and the characteristic graph in which the loom failure causes are classified and organized, is used in the analysis. The knowledge for characteristic graph is organized, and an effective inference engine- is developed. The developed system is tested and modified using hypothetical loom failure causes, and the feasibility of the expert system application to extend the functions of the loom monitoring system is proved.
