Informal engineering education program for high school students was developed to cultivate engineering literacy using the human resources and facilities of university. Plant factory, a smart farming technology, was selected as a main theme, and the novel engineering camp program involving engineering design activities and intra-linter-team works was planned. The camp program was applied to 38 high school students in an active learning classroom. Five teams were constructed according to elemental technologies such as biotechnology, information-communication technology, energy engineering, mechanical engineering and architectural engineering, and the students were participated in intra- and inter-team activities to achieve the final goal of 'the construction of a plant factory in school'. The team works were conducted according to the eight steps of engineering design process (identifying the problem and need, identifying criteria and constraints, brainstorming possible solutions, selecting the best possible solution, constructing a prototype, testing and evaluating the solution, communicating the solution, and refining design). Participants' satisfaction survey showed that the satisfaction on the contents of engineering design was 4.48 on 5-point Likert scale. The participants' satisfaction on creative activity and systematic methodology was 4.43 on 5-point Likert scale. 97% of participants responded positively to team works, and 92% of participants were satisfied with career mentoring activity supplied by undergraduate/graduate students. These results indicates that the engineering camp program involving engineering design activity and intra-/inter-team works can contribute to cultivate engineering literacy such as creativity, problem solving ability, collaboration, communication skills for high school students, and to increase their interests in engineering fields.

This paper deals with the practical experience and lessons to develop a method of course-embedded assessment for program outcomes in Computer Science & Information Engineering. In engineering education, ABEEK(Accreditation Board for Engineering Education of Korea) has been nominated as an official accreditation from Korean government under some conditions of fulfillment. One of the conditions is enforcement of course-embedded assessment for program outcomes. In this paper, a method of course-embedded assessment in Computer Science & Information Engineering is suggested. The case study was done in a basic project course which includes the special assessment methods in project courses. The case study of course-embedded assessment in a basic project course was given with consideration for each step, that is, set up of program outcomes which are highly related to the course, selection of assessment tools such as written examination and project-based assessment, set up of assessment criteria, implementation of course-embedded assessment, and analysis of results. The proposed method is expected to be a good example to construct the whole strategy for course-embedded assessment in Computer Science & Information Engineering.

가상현실은 시·공간을 초월하는 경험이 가능하며 아이들의 몰입감과 학습효과를 높일 수 있어 교육 도구로서의 가치를 인정받고 있다. 정부는 VR 기기를 전국의 초등학교에 보급하고 있지만, 양질의 교육용 실감형 콘텐츠는 부족한 상황이다. 따라서, 본 논문에서는 가상현실 기술을 활용한 국악기 연주 체험 프로그램을 제안하였다. Unity의 물리 엔진과 Oculus의 햅틱 기능을 이용하여 전통 국악기 중 편경을 실감 나게 연주할 수 있도록 가상환경을 구현하였다. 리듬 게임 형식을 적용하여 아이들의 흥미 또한 유발하였다. 이 프로그램을 통해 국악기를 직접 연주하며 해당 국악기에 대한 지식을 자연스럽게 습득할 수 있을 것이라 기대한다.

유한차분시간영역 방법은 전자기파 관련 분야의 전산모사에 많이 사용되는 수치해석기법이다. 이 방법을 이용하여 구현한 전산모사 프로그램은 많은 계산 자원 필요로 하기 때문에 병렬 계산 환경을 이용하게 되는 경우가 많다. 병렬 계산 환경에서 전산모사를 수행할 경우, 병렬로 수행되는 각 프로세스 간의 통신 속도와 네트워크의 지연 시간은 계산의 병목 현상을 초래하여 전체적인 성능을 저하시키는 원인이 된다. 따라서, 본 논문에서는 MPI의 지속 통신 메커니즘을 이용하여 병렬 프로세스 간 동기화 속도를 증가시킴으로써 유한차분시간영역 전산모사 프로그램에서의 MPI 통신 성능의 향상을 꾀하고, 그 결과를 그래프로 도시하였다. 또한 기존의 양방향 통신과 단방향 통신 메커니즘을 사용했을 때의 성능과 비교/분석하여, 병렬 유한차분시간영역 전산모사 프로그램에 있어서 지속 통신 메커니즘의 장/단점을 제시하고, 그 효용성에 관해 논의한다.

Google Android employs a security model based on application permissions to control accesses to system resources and components of other applications from a potentially malicious program. But, this model has security vulnerabilities due to lack of user comprehension and excessive permission requests by 3rd party applications. Broadcast intent message is widely used as a primary means of communication among internal application components. However, this mechanism has also potential security problems because it has no security policy related with it. In this paper, we first present security breach scenarios caused by inappropriate use of application permissions and broadcast intent messages. We then analyze and compare usage patterns of application permissions and broadcast intent message for popular applications on Android market and malwares, respectively. The analysis results show that there exists a characteristic set for application permissions and broadcast intent receiver that are requested by typical malwares. Based on the results, we propose a scheme to detect applications that are suspected as malicious and notify the result to users at installation time.
