The greenhouse control system is designed by personal computer. This system should observe and control the growth conditions for crops in both plastic film and glass greenhouses. In this contribution puts emphasis on graphical user interface for greenhouse control system by personal computer under the aim of creating safer, more effective and more economical services. This system is developed for the requirements of the intelligent greenhouse control system and gives a lot of convenience for farmer who is not familiar with pc technique. The GUI and control system are programmed by Visual C++ and Visual Basic.

국내 휴대용PC 산업은 생산 및 수출의 대부분이 중견기업 이상으로 구성되어 있으며, 주요 생산업체들이 제품의 중요성을 인식하여 생산 및 수출을 계속 증가시키고 있으나 수출의 대부분이 PC대형 벤더들의 OEM으로 세계 시장에 자체 브랜드 제품이 없어 산업기반이 미흡한 실정이다. 이에 국내에서 생산되는 휴대용 PC의 제품수준을 파악하고 산업의 특성 등을 관련 자료의 수집 및 분석, 제조사 면담조사 및 유통업체 설문조사를 적용해 체계적으로 분석함으로써 산업경쟁력을 제고하고 산업피해를 사전에 예방함은 물론 무역수지를 개선할 수 있는 방안을 모색하고자 한다.

Vehicle simulators provide an effective and safe environment for training operators. Many vehicle simulators have been developed but only a few have reached the stage of widely available tools; these tools are usually expensive and run on workstations only We have developed a low-cost, PC-based excavator simulator for training operators. Currently the simulator is dedicated to operating the boom, Em, bucket, and driver's cabin for digging by the action of the operator on two joysticks. This paper presents the implementation of the excavator simulator and some implementation results.

본 논문에서는 이진화된 영상에서의 2차원 정보와 그레이 영상에서의 3차원 프로파일 정보를 이용하여 BGA의 불량 상태를 시각적으로 검사하는 시스템에 대해서 기술한다. BGA의 결함을 자동으로 판정하기 위해 사용된 알고리즘은 이진 영상에서의 특징점들과 그레이영상의 3차원 프로파일 정보를 이용한 모델 정합 기술을 이용한다. 두가지 단계를 분리 검사함으로써 생산라인에서 초기에 에러를 검출해낼 수 있는 잇점이 있다. 그러나 조명이 열악한 경우에는 에러 인식율이 낮아진다.

To control a greenhouse is to control environmental parameters in greenhouse. Controlled environments may be as simple as saran-covered shade houses or as complex as growth chambers. Although greenhouses are probably the most common example of a controlled environment used in agricultural/horticultural production, the type of controlled environment or system that is needed depends upon the climate, time of year, crops being produced and the environmental parameters that must be controlled. In this contribution puts emphasis on construction of automatic-controlled greenhouse system by personal computer.

The flight simulator should be made like a actual flight. For the scene of sight, instrument should show the condition of flight and the pilot should catch the altitude, speed, pose and rate of lift of the airplane. This paper describes visual training program of driving airplane in practice. It is for beginners using joystick in PC, implements airplane physical equations. Flight simulator in it implements airplane panel parts in order to make simple modeling, And it uses rendering technology to implement vision parts of panel. It uses double buffering In make it faster and more efficient..
