This study is designed integration and control system of GaAs bonding system consisted of multi-processing using DeviceNet and GEM-Protocol. Developing bonding system is composed of resin coating, pre-baking pre-aligner, bonding, material handler(flip robot), and wafer cassette, etc. This system has process-fluent of each a process and share information using GEM-protocol. This study devised virtual bonding simulator to control and to monitor bonding system efficiently. Also we can verify optimizing of system previously through a virtual bonding simulator.

This paper introduces an integration of Product Data Management (PDM) and Software Configuration Management (SCM). PDM and SCM have supported development of mechanical products and software products respectively. The importance of software components in the current products increases rapidly since the software enables the products to satisfy various customer requirements efficiently. Therefore the current product development needs enhanced product data management that can control both the hardware and software data seamlessly. This paper proposes an extended product data model for integrating SCM into PDM. The extension enables PDM document management to support the version control for software development. It also enables engineers to control both the software and hardware parts as integrated data objects during product configuration and engineering change management. The proposed model is implemented by using a commercial Product Lifecycle Management (PLM) system and a development of a network based robot system is tested by the implemented product development environment.

Various bioinformatics tools for biological data processing have been developed and most of them are available in public. Most bioinformatics works are carried out by a composite application of those tools. Several integration approaches have been proposed for easy use of the tools. This paper proposes a new multi agent system to integrate bioinformatics tools in the perspective of workflow since the composite applications of tools can be regarded as workflows. For the easy integration, the proposed system employs wrapper agents for existing tools, uses XML-based messages in the inter-agent communication, and agents are supposed to extract necessary information from the received messages. This allows new tools to be easily added on the integration framework. The proposed method allows various control structures in workflow definition and provides the progress monitoring capability of the on-going workflows. In particular, agents in this system have the rule-based architecture which allows the defined rule set to be a special role agent. This feature provides fast and flexible agent development to aid in managing the complexity of bioinformatics application. This system has been partially implemented and has been proven to be a viable implementation for workflow-based bioinformatics tool integration.

KASS (korea augmentation satellite system) 시스템 통합 및 검증(IVQ; integration, verification, qualification) 활동은 시스템 및 하위시스템 요구사항 검증 활동으로 IART(inspection, analysis, review of design, test) 기반으로 상세설계 (CDR; critical design review) 이후 하위시스템 공장수락시험 (FAT; factory acceptance test)부터 현장수락시험 (SAT; site acceptance test) 그리고 시스템 통합 검증 시험 (TRR; test readiness review) 까지 수행하였다. FAT 단계의 활동은 개발된 장비를 테스트 플랫폼에 설치하고 각 장비별 인터페이스 검증과 통합운영국(KCS; kass control station)과의 연동시험을 통해 성능을 검증하였다. SAT 단계의 활동은 FAT 단계에서 검증된 KRS (kass reference station), KPS (kass processing station), KUS (kass uplink station), KCS를 운영 현장에 설치하고 검증하는 단계이며 개발 일정 및 여건을 고려하여 3단계로 구분하여 수행하였다. TRR 단계의 활동은 항공위성1호기에서 방송되는 SBAS (satellite based augmentation system) 메시지를 이용하여 SAT을 통해 검증된 장비를 FAT 단계에 수행했던 시험 항목과 추가 시험 항목 검증을 통해 전체 시스템에 대한 성능 검증을 완료하였다.

Expose equipment system that is used for manufacturing process of Flat Panel Display, is most important equipment in whole process. Expose equipment that is for making pattern of mask on substrate, consists of optical part, stage part and transport part. The stage is an important part that aligns mask and substrate for delivering pattern of mask to substrate exactly. In this paper, control system of expose stage that is able to use mask and substrate of diverse size, with PC controller using GUI interface instead of PLC control system. The existing PLC control system does not have the suitable structure for using mask of diverse size. GUI interface integration control system is based on PC. So it has the advantage of convenient use and active operation. We embodied PLC control system in integration control system based on PC, and verified utility possibility through the standard test course.

Most power steering systems obtain the power by a hydraulic mechanism. Therefore, it consumes more energy because the oil power should be sustained all the times. Recently, to solve this problem the electric power system has been developed and become widely equipped in passenger vehicles. In this research the simulation integration technique for an electric power steering system with MATLAB/SIMULINK and a full vehicle model with ADAMS has been developed. A full vehicle model interacted with electronic control unit algorithm is concurrently simulated with an impulsive steering wheel torque input. The dynamic responses of vehicle chassis and steering system are evaluated. This integrated method allows engineers to reduce the prototype testing cost and to shorten the developing period.

A PWM switching control strategy based on instantaneous integration concept for reducing hamonic components of inverter system with fluctuating input voltage is presented. Applying this strategy to single phase full bridge PWM inverter through bipolor switching method and unipolor switching method, reduction of hamonic components of output voltage and current is demonstrated through simulation. The system operation is examined and confirmed by experiments.
