This paper is concerned with the compression test such as compression and ring compression tests, by using virtual reality. Engineering material laboratory can be carried out on personal computer without the real expensive experiment devices. The virtual laboratory is composed of three modules as input, calculation and output module on internet. Internet user can give the material's property and other parameters to the server computer at the input module. On the calculation module, simulator cimputes the results by analysis program and store the data as a file. The output module is the program that internet user can confirm a virtual compression results by showing a table, graph, and 3D animation. This program is designed by Internet language such as HTML, CGI, VRML, JAVA. And analysis program uses the finite element method with fortran language. Since the study of virtual reality on internet is rapidly increasing, the virtual experiment of technique will substitute many real experiments in the future.

This study aimed to investigate the effect of adolescent development environment including parenting attitude, peer relationship, and school environment on delinquent behavior, and between these relationships, the mediate effect of media environment such as computer and mobile devices. The $6^{th}$ year data from Korean Children & Youth Panel Survey (KCYPS) was used and the subjects were limited to 518 students of $7^{th}$ grade who are in their early adolescence. The result shows that adolescents under more affectionate, over involvement, and abusive parenting attitude will commit delinquent behaviors more frequently, and so does alienated youth from their friends. Parenting inconsistency and communication with friends make them use computer and cell phone more often, and excessive media usage increases adolescent's delinquent behavior. In conclusion, family environment and peer relation have influence on adolescents' delinquent behavior. Therefore, there is necessity to build development environment that prevent adolescents' delinquencies like parent education program or peer communication program for example. Also, proper education program for using computer or cell phone usage can reduce adolescents' delinquent behaviors, especially when its addictive aspect was recently issued.

The aim of this study is to investigate the demographical differences in technostressors(cause technological stresses). Although previous studies have been conducted to investigate the factors that affect technostress, little studies have examined the differences in demographic factors. Therefore, this study empirically attempts to investigate how level of technostressors differ by demographic factors. Independent sample t-test was used to identify differences after dividing sample into two groups. The technostressors used in this work are work overload, life invasion, complexity of technology, job insecurity, pace of technological change. We found that, sex and position show a significant difference in pace of technological change. In the educational level, there is a difference between work overload. Work overload, life invasion, complexity of technology, and pace of change show differences in age group. In computer knowledge, there are differences in complexity technology, job insecurity, and pace of change. On the other hand, there is no difference in computer using hours. Conclusions and implications are discussed in final section.

This paper evaluates the appropriateness of the proposed robot education curriculum to consider conceptual understanding and learning activities model considering the curriculum and achievement criteria in order to make it easier to apply for a course in robot area. The professors of dept. of computer education at national universities of education reviewed the importance of education contents system and appropriateness of education period. Based on the results of the review, the conceptual elements and achievement standards of each sub-area were revised and supplemented, and then evaluated in three stages. Finally, the educational elements of the concept factors and achievement criteria were agreed upon. The proposed robotic computing education information systems and the achievement standards for schools in the area, as well as to match the grade level of the students without distinction variety of robots will be able to take advantage of computing education activities to reorganize the robot computing courses.

컴퓨터의 개발과 발달은 교육 환경상에 변화를 가져왔다. 초기 본인에게 부족한 부분을 보충 하는 자료를 이용할 수 있는 보조 교재 등의 형태로 나타났으며, 멀티미디어의 등장은 보충교재로의 질을 한 단계 증가시키는 계기를 마련하였다. 인터넷의 급속한 보급과 발달은 멀티미디어의 쉬운 접근과 다양한 형태를 획득할 수 있는 방법을 마련하여, 원격교육상에서 많은 활용이 가능하게 되었다. 하지만, 현재 인터넷을 이용한 평가의 경우 대부분 현재 학교에서 이루어지고 있는 평가와 유사한 단순한 텍스트와 간단한 그림등을 포함한 형태나 동영상등 멀티미디어와 문제는 별개인 형태로 행해지고 있다. 다양한 멀티미디어 자료를 활용하기 위해서 각 멀티미디어의 특성들과 문제의 특성을 고려해서 요소들 간에 동기화를 나타내기 위해서 SMIL을 확장한 방법을 이용하였다. 또한, 교수가 출제된 문제에 대해서 평가 등에 활용시에 현재 시스템들은 수정이 불가능하여 평가의 정확성을 떨어뜨리는 요인으로 작용한다. 본 논문에서는 교수와 문제의 상호작용을 통한 실시간 문제 수정기능과 과목별 특성을 고려한 멀티미디어 요소와 문제를 결합한 실시간 학습평가 시스템을 설계, 구현하였다.

최근 사물인터넷(IoT)이 도래함에 따라 IT 산업을 중심으로 소프트웨어의 활용 용도가 컴퓨터 뿐 아니라, 의료, 교육, 금융, 자동차, 에너지 등 다양한 분야에서 활용되고 있다. 이처럼 소프트웨어 활용 분야가 본격적으로 확산됨에 따라 소프트웨어 보안 취약점을 이용한 공격위험 또한 증가하고 있으며, 이에 따라 시큐어코딩의 중요성이 부각되고 있다. 본 논문에서는 기존 시큐어코딩 관리 시스템 환경에서 효율적인 시큐어코딩 관리를 위해 운영서버와 Program Server를 이용한 시큐어코딩 관리 시스템 향상 방안을 제안한다. 제안하는 시스템을 시큐어코딩 프로그램에 적용한다면, 시큐어코딩 프로그램 성능향상과 효율적인 시큐어코딩 시스템 관리에 도움이 될 것으로 기대된다.
