The worldwide web provides new opportunities for distributing all learning materials over the internet. The worldwide web enables learner to have easy access to all learning materials over the internet at anytime, anywhere. In this paper a Web-based Integrated compiler System for Engineering Education Combined with Remote Hardware Control is proposed. Learners can solve comprehensive engineering problems economically and effectively from programming language to various application programs including microprocessor experiment using the system. At anytime and anywhere, learners can have access to the system and study subjects without their own compiler or application programs. The proposed system is integrated with compilers about C programming language, Matlab, MASM and ATmega128 microcontroller in the sever system. The system will help the learners learn programming knowledge and skills highly desired in modern engineering problem solving.

본 연구에서는 스마트폰 환경에서 운영되는 안드로이드 기반 평가 시스템을 개발하였다. 기존의 학생들은 강의실에서 시험지로 시험을 보았다. 그리고 조금 더 발전된 형태로 인터넷을 이용한 PC환경의 시험을 보아왔다. 하지만 이런 유형의 시험은 강의실이나 PC라는 제한된 조건이 충족되어야만 가능한 것이었다. 이를 해결하기 위해서 본 연구에서는 스마트폰 환경에서 데이터베이스와 연동된 평가 시스템을 구현하게 되었다. In this paper, we proposed an Android based evaluation system in the smartphone environment. The students try to test with the examination paper in the classroom or to test online using internet at the PC. But the type of the examinantion is available in case of solving the restricted conditions such as classroom and PC. Therefore in order to solve the problem, we implemented Mysql databse based evaluation system under the smartphone environment.

In this paper, We implement a record of students attendance about a lot of subjects being done by a student and a professor in educational system. The student administration system beased .NET deals effectively with affairs about a control service of students. The system is largely divided into student administration server system, student administration client system, and a record of students attendance system. The student administration sever system is made of database, web server and system control server. The client system is made of a student administration module for a professor and taking a lecture administration module. Finally, the student attendance system is made of an auto-attendance machinery and an attendance check module. The auto-attendance check is proceeding through a bar code perception.

In C language programming practice, students work together in presence of teaching assistant or professor in the laboratory. But on case of their practice at student’s home or any other place where professor or teaching assistant do not exist. they cannot discuss and get some help. A web-based cooperative learning helps learner learn problem solving under the conversation and debate at any time, anywhere. In the paper we proposed a web-based cooperative learning system with chatting window. Thus learner can practice c programming language with others and they can confirm the execution result of their program. in the system. The proposed system has a feature of sharing with chatting and C language source code window. The system shows that cooperative learning which students attend the bubble sort project proceed well.

In this paper we designed and implemented an embedded RFID middleware system based Windows CE. In order to verify the implemented system we implemented book lending administration system, as the result we confirmed smooth data flow and exact operation. With advantages of embedded systems, the proposed embedded RFID middle-ware system is cheaper than RFID enterprise middle-ware, which accounts for the majority of existing RFID middle ware products, and easy to install and maintain, which makes the system ideal for small-scaled projects.

A remote laboratory education, which has been developed to overcome the limitation which students can not perform real experiments in the virtual education system, allows students to implement actual experiments from a distant place and observe the results. The existing remote laboratory system only implements a designated lab, and in order to provide a new laboratory, it requires new arrangements for the place and elements that are proper for the lab, which is inconvenient. This problem can be a weakness in changing laboratory subjects dynamically or when making slight changes to a laboratory. Hence, this study suggests a remote electric laboratory system that requires a small space and can be controlled remotely by utilizing equipments that can be used to make variable circuit patterns, based on the ATmega128 and relay control technology, and by utilizing LabVIEW. The system enables the dynamic transformation of a circuit pattern, and it also provides the connection or circuit breaker functions by selecting the laboratory elements that will interact with the circuit along with the measurement terminal of the measuring device.

In this study, we implement a remote laboratory for circuit theory using LabVIEW. The variable resister module is developed and used in the remote laboratory. The proposed module is device which is combined with resister module(STM600R) and stepping motor. The output of the device is measured using by DAQ. The DAQ gets the value and then it is displayed in the program. Therefore we can control resister value remotely. The implemented device will be used in the laboratory which students can perform an experiment at anytime and anywhere.
