Recently the number of lectures of offered as part of distance education courses is increasing due to the necessity of continuing education in this era of rapidly changing technologies. To promote this, Web-based distance education systems have been developed and put into practical use. To step further, we propose a virtual space, distance education platform called interactive virtual laboratory. The proposed system is expected to overcome many obstacles in performing the unit operations laboratory at the current setting. The server/client system implementation was programmed with ASP and Visual Basic. The availability of simple and efficient technological supports for dissemination and remote use of virtual lab systems supports more experimental practices regardless of the number of participating students and their locations. Variety of instruments, process equipments and lab procedures are being added to make it a complete package of virtual lab fur undergraduate unit operations course.

Airborne laser scanning thechnology has been studied in many applications, DSM(Digital Surface Model) development, building extraction, 3D virtual city modeling. In this paper, we will evaluate the possibility of airborne laser scanning technology for transportation application, especially for recognizing moving vehicles on road. First, we initially segment the region of roads from all LiDAR DATA using the GIS map and intensity image. Secondly, the segmented region is divided into the roads and vehicles using the height threshold value of local based window. Finally, the vehicles will be classified into the several types of vehicles by MDC(Minimum Distance Classification) method using the vehicle's geometry information, height, length, width, etc

학습효율의 향상을 위해 본 논문에서는 웹기반 가상실험시스템과 원격실험시스템을 적절하게 통합하여 전기전자회로에 대한 하이브리드 실험시스템을 구현하였다. 먼저, 전기/전자회로 실험에 대한 웹기반 가상실험실을 개발하여 개념학습, 가상실험, 평가등의 3개의 주요 세션과 그에 대한 관리시스템으로 구성하였다. 다음으로 가상실험을 진행하는 동안 발생할 수 있는 현실감의 부족성 문제를 해결하기 위해 전기전자회로에 대한 원격실험시스템을 구현하였다. 제안된 가상/원격실험시스템은 독립적인 형태로 사용될 수도 있지만, 학습효율을 극대화하기 위해서 두 개의 시스템을 통합하여 하이브리드 전기전자 실험시스템을 구현하였다.

인터넷기술의 눈부신 발전으로, 대학 및 교육기관에서는 인터넷을 통하여 많은 e-learning 강좌를 제공하고 있어 시간과 거리상 제약을 받고 있는 많은 학생들에게 혜택을 주고 있다. 그럼에도 불구하고, 대부분의 웹기반 강좌는 공학기술교육의 필요성을 충족시킬 수 없었다. 본 논문에서는 산업 자동화 교육 훈련을 위한 웹기반 PLC 실험실의 설계와 구현을 제안하였다. 제안된 웹기반 PLC 실험실 시스템은 가상실험실과 원격실험실로 구성하였다. 웹기반 PLC 실험실은 많은 추가 비용 없이 교육의 질을 높이면서 등록된 학생들이 집에서 접속이 가능하다. 학생들은 웹 카메라의 도움으로 인터넷을 통하여 실제와 같은 PLC 실험을 보다 잘 경험 할 수 있다.

The full nonlinear equations of an unmanned aerial vehicle ground taxiing mathematical dynamic model are built based on a type of unmanned aerial vehicle data in LMS Virtual.Lab Motion. The flexible landing gear model is considered to make the aircraft ground motion more accurate. The electric braking control system is established in MATLAB/Simulink and the experiment of it verifies that the electric braking model with the pressure sensor is fitted well with the actual braking mechanism and it ensures the braking response speediness. The direction rectification control law combining the differential brake and the rudder with 30% anti-skid brake is built to improve the directional stability. Two other rectifying control laws are demonstrated to compare with the designed control law to verify that the designed control is of high directional stability and high braking efficiency. The lateral displacement increases by 445.45% with poor rectification performance under the only rudder rectifying control relative to the designed control law. The braking distance rises by 36m and the braking frequency increases by 85.71% under the control law without anti-skid brake. Different landing conditions are simulated to verify the good robustness of the designed rectifying control.
