초.중등학교에서 활용중인 종합정보관리 시스템 중에서 시설.장비관리 행정시스템은 교육청 단위로의 DB 통합과 전국단위 교육행정정보시스템의 구축, 현장 적합도와 사용자 편이성 미흡 등의 이유로 사용이 중단되어 있다. 이와 같은 문제점을 해결하기 위해서는 시스템의 재구축 또는 개정작업이 수반된다. 이러한 개정의 한 방안으로 워크플로우 시스템 도임을 검토하였다. 워크플로우 시스템을 시설.장비관리 행정시스템에 도입하여 운영함으로써 학교종합정보관리 시스템이 업무변화에 대하여 탄력적으로 개선될 수 있음을 보였다.

This study inquired following research questions by a narrative research method : What was the job of an engineer in mechanical design field? How did he fulfill his job-related learning in his workplace? What were the context and the characteristic of the job-related learning in the workplace? And some implications of the job-related learning on engineering education were discussed. We identified that the research participant's career as a mechanical engineer has developed through three stages. At first, he engaged on conceptual design of a semi-conductor test machine through self-initiated learning from basic to whole system of the machine. At second stage, he leaded a design group for the concrete design of a ball type semi-conductor test machine. In this stage he learned the meaning of cooperation and cooperative learning. At third stage, he initiated to found an entrepreneur company that was specified to design a semi-conductor test machine. He became CEO of the company. He learned the R & D policy making through contacts with global company, visiting exhibition in abroad. Eventually his main task as a mechanical engineer was the problem solving in the process of machine design. He had experienced and learned through his works : project management, independent fulfilling of tasks, functional analysis and reverse engineering, conceptualizing and test, cohesive cooperation, dialogue and discussion, mediation of conflict, human relationship, leadership. The implication of the narrative analysis on engineering education is, proposed, to give the students more chances to experience and to learn such activities.

Education equipment for field programmable gate array (FPGA) design of sensor-based IOT (Internet Of Thing) system is introduced. Because sensors have different interfaces, several types of interface controller on FPGA need. Using this equipment, several types of interface controller, which can control ADC (analog-to-digital converter) for analog sensor outputs and $I^2C$ (Inter-Integrated Circuit), SPI (Serial Peripheral Interface Bus), and GPIO (General-Purpose Input/Output) for digital sensor outputs, can be designed on FPGA. Image processing hardware using image sensors and display controller for real and image-processed images or videos can be design on FPGA chip. This equipment can design a SOC (System On Chip) consisting of a hard process core on Linux OS and a FPGA block for IOT system which can communicate with wire and wireless networks. Using the education equipment, an example of hardware design using image sensor and accelerometer is described, and an example of syllabus for "Digital system design using FPGA" course is introduced. Using the education equipment, students can develop the ability to design some hardware, and to train the ability for the creative capstone design through conceptual, partial-level, and detail designs.

This paper presents the design of the educational router system. This system is designed and implemented to support network configuration and embedded programming technology of the user on Internet. Not only Static routing protocol but also a kind of dynamic routing protocols such as OSPF and RIP and firewall have been programmed for education based on ethernet interface. ADS 1.2 as debugging environment, uC/OS-ii as RTOS and C language as development language are used. The educational procedures is compile, loading of static routing protocol, a kind of dynamic routing protocols such as OSPF and RIP and firewall program already supplied. Thereafter the verification is checked by using "ping" test to allow for demo operation such as hands-on training procedure. Finally programming procedure similar with demo operation of static routing protocol, a kind of dynamic routing protocols such as OSPF and RIP and packet filtering function is educated step by step.

Research-based professional development is essential for in-service and pre-service science teachers across the nation. The purpose of this study was to examine in-service science teachers' and pre-service teachers' perception of the training program for professional development using advanced science laboratory equipment and experiments. Science teachers (N= 43) in science high schools and pre-service science teachers (N=189) were selected as research subjects. As a result of this study, in-service teachers and pre-service teachers recognized that they lacked understanding and experience in advanced science laboratory equipment, although they perceived the importance of its use. They wanted to attend training programs during vacation if they would have the opportunity. Both groups felt that they needed to improve their ability to operate the advanced science lab equipment, preferring to practice these instruments in the training programs. In-service teachers preferred the development of teaching and learning programs for use of the advanced science laboratory equipment. However, pre-service teachers preferred using the advanced science laboratory equipment. The study gives implications for teachers' professional development.

There are two ways of wireless network practice. One of the ways is to use wireless network equipments directly. And the other way is to use wireless network simulators. But they have some problems such that space limitation, required equipments and setting up the simulators for each wireless network practices. So, in this paper, we showed the model of application for students and professor is modeled from real practice environment. We also suggested algorithms for implementation of an application about wireless network practice based on web.

본 연구에서 구축한 PC-based GIS는 소규모 예산의 교육용 및 연구용 시스템이다. OSU MAP은 PC XT에서도 운용되기 때문에 최저 157만원선(CPU 100만원+디지타이저 50만원+소프트웨어 7만원)으로 장비할 수 있다. 그러나, AT386기종에 값싼 디지타이저와 선형배열스캔너를 부착한 하드웨어 시스템과 래스터/벡터 자료구조의 소프트웨어 시스템을 장비하는 데에는 약 2000만원 선 (CPU 500만원+디지타이저 50만원+스캔너 300만원+소프트웨어 1000만원)이 소요된다. 6-7년 전에 이와 유사한 처리능력의 32비트 기기를 장비하려면 최소한 3억원의 예산이 소요되었던 것을 고려하면 대단한 가격하락이다. 이제, 우리나라에서도 약간의 지혜와 성실을 바탕으로 교육용 및 연구목적의 GIS를 향유할 수 있게 되었다.
