The purpose of this study is to develop a debugging task to support process-centered assessment on software(SW) education and to develop a service site. Achievement criteria for programming in elementary and middle school SW curriculum consists of control structures such as repetition and condition, and elements such as variables and input/output. In order to apply the process-centered assessment presented by the Ministry of Education, it is necessary to present tasks that can be used in the actual classroom environment and to consider connection with achievement levels. Therefore, in this study, 12 tasks for elementary school and 15 tasks for middle school were developed as debugging tasks and their validity was verified. As a result of conducting Delphi verification for validity, it was found that the level and content of the debugging task are appropriate. In addition, as a result of verifying the usability of the debugging challenge site by applying a heuristic evaluation method, it was found that it is suitable for use in the real educational field.

전자/통신기기에 대한 전자파 장해(EMl/EMS) 문제를 제품개발 기간 내에 완전하게 해결하기란 이론만큼 쉽지 않으며, 전자기적 적합성(EMC)에 대한 지식이 충분하지 못한 회로/기구 설계자들은 전자 파장해 문제를 반복적인 설계 수정 및 디버깅 작업으로 밖에 해결할 수 없는 골치 아픈 Black Magic으로 생각하고 있다. 그러나 분명히 전자기적 간섭(EMI) 문제도 이론 및 해석적인 접근으로 그 해답을 충분히 찾을 수가 있다, 본 고에서는 이러한 PCB Level에서의 전자파장해 문제를 해결하기 위한 체계적인 접근 방법과 오랜 현장 경험에서 나오는 EMC 전문가의 경험적인 지식을 통합한 인공 지능형 EMC 전문가 시스템에 대한 소개와 연구개발 동향 및 극복 과제 등에 대해서 기술하고자 한다.

One of the most significant tasks of software development project is to know how much it will be the software development cost in the early stage of software development cycle. The software development environment and technology are changing very rapidly. For accuracy, we should apply those to the software cost estimation. And it is important that we select the suitable adjustment factor and the value of a suitable adjustment factor. For that, this paper have applied the method of AHP. And we have also analyzed the sensitivity of the adjustment factor which is influenced by decision metrics. In conclusion, the value of the application type adjustment factor is responded more sensitively to the data complexity and the control complexity than processing complexity. And the value of the language adjustment factor is responded more sensitively to the supplying manpower and the time of the coding than the time of the debugging. In the future, we will research the selection of an additional adjustment factor and a suitable value of the adjustment factor which are influenced by the environment and the technology of the domestic software development. And then, in the language adjustment factor, we will try to calculate the value about the individual programming language.
