정보통신 공학의 발달은 학교교육에서도 새로운 패러다임을 요구하고 있다. 학습의 정의, 학습 방법, 교사의 역할, 학습 환경에 있어서의 변화를 가져왔다. 새로운 교육 패러다임인 구성주의 교수 원리를 학교 교육에 실현하는데 적합한 인터넷의 교육적 특성을 알아보고, 원격교육의 매체로써 인터넷이 가지는 특성을 살펴보았다.

The objective of this study was to develop curriculum for successful articulation education program between department of information processing in Daejonsinil vocational high school and school of computer & communication in Hyechon College. This study was carried out through review of literature, survey and discussions with panels of judges composed of experts in the related fields. Gap analysis was used to interpret the survey results. Based on the results of this study, several educational needs and recommendations for articulation education of computer & communication area both in vocational high school and college were suggested.

DTN (Delay Tolerant Network)은 종단 간 연결성이 보장되지 않는 환경에서의 통신을 위해 메시지 전송 방식으로 "저장 과 운반 및 전달 (Store, Carry and Forward)"을 수행하는 라우팅 방식과 불안정한 네트워크에서 메시지를 전달하기 위해 번들(Bundle)이라는 추가적인 계층을 통해 통신을 하는 네트워크이다. 본 논문은 MIT에서 개발한 Arduino라는 마이크로 컨트롤로 보드와 IEEE802.15.4를 기반으로 하는 Zigbee 통신을 가능케 하는 XBee 모듈을 이용하여 DTN을 구현한 결과를 제시하고 구현된 DTN 환경에서 Relay Node의 속도 변화에 따라 메시지 전달 시간의 변화를 보인다.

Deaf are it is difficult to communicate to represent the voice heard, so theay use mostly using the speech, sign language, writing, etc. to communicate. It is the best way to use sign language, in order to communicate deaf and normal people each other. But they must understand to use sign language. In this paper, we designed and implementated finger language translation system to support communicate between deaf and normal people. We used leap motion as input device that can track finger and hand gesture. We used raspberry pi that is low power sing board computer to process input data and translate finger language. We implemented application used Node.js and MongoDB. The client application complied with HTML5 so that can be support any smart device with web browser.

In seventh curriculum policy, operating the computer education is divided into two parts: they are the information communication technology (ICT) education and related areas in the computer curriculum. This study compares and analyzes the learning contents of "enjoyable computer"-ICT education teaching materials of Busan elementary schools. This paper researches the trend and the actual condition of computer education in foreign countries, and it surveys teachers and students to find out the recognition and demands of computer education. And this paper examines the revised Operating Guide of ICT Education and it compares to the contents system of current curriculum and demands of students and teachers.

In the basis on the revised Information and Communications Technology guidelines at elementary and middle school, it is newly emphasized in 3rd stage of ICT guidelines that the programming education is needed to cope with information-oriented society at the elementary school. But, it is a little difficult for the young students to learn how to make program. In this paper, we suggest a programming education curriculum with Scratch Language and educational contents for the elementary student.

ICT 기술이 발전하면서 놀이동산 같은 체험이 필요한 것들까지도 디지털화 하는 것이 가능하게 되었다. 최근에는 가상현실 기술을 이용하여 컴퓨터 시뮬레이션으로 창출된 3차원 가상공간에서 사용자의 오감 경험을 확장하고 공유함으로서, 기존의 놀이동산 게임에서 느낄 수 없는 3차원 현실세계와 유사한 경험을 추구할 수 있게 되었다. 따라서 본 논문에서는 가상현실을 이용하여 유저와 상호작용하고, 사용자에게 현실과 유사한 즐거움을 줄 수 있는 놀이동산 테마파크 게임을 개발하였다. 본 연구의 놀이동산 테마파크 게임은 Eon Studio 개발툴과 JavaScript를 이용하여 구현되었으며, Eon I-CUBE안에서 1인칭 주인공 시점으로 게임을 진행하도록 하였다. 또한 유저가 선택한 스토리 중심으로 놀이동산 테마파크를 구현하였다.

In this paper, we studied accident-aware smart streetlights to prevent secondary accidents when driving on highways. It used Arduino and sensors to inform drivers of weather conditions, incorporated functions such as LED brightness control according to sunlight and night driving vehicles, and used Raspberry Pi camera OpenCV to learn various traffic accidents, natural disasters, and wildlife.

In this paper, we will make a model that finds optimal phase for each crossroad. When the traffic volume, traffic capacity, and the lane width of every direction is given for each crossroad, we aim to find the most efficient phase. We established an evaluation function that evaluates the efficiency of each phase using the values of the average waiting time in one direction, the average delay time, the standard deviation of the delay time, and the average delay time in each direction. The time allocation to optimize a phase pattern can be obtained by using the gradient decent method. Through this research, we hope to decrease the waiting time in transporation, thus improving the overall traffic condition in cities.

With the development of precision facility technology, the importance of four-axis CNC precision processing technology is increasing. However, due to complex shape processing, it is difficult to operate the system. This paper compared precision control and efficiency by manufacturing a four-axis control structure to solve this problem and implementing Bresenham's Line Algorithm and Runspeed Algorithm without using commercial programs. When Runspeed was applied, there was an error improvement of about 12.03% and curvature accuracy improvement compared to Bresenham. It was confirmed that precise processing was possible to a three-dimensional structure by driving a rotary shaft A motor.
