최근 들어, 모바일 장치의 성능이 향상되고 보급률이 증대됨에 따라 모바일 장치를 그리드 자원으로 이용하기 위한 모바일 그리드가 등장하였다. 그러나 모바일 장치가 가지는 무선기기로써의 제약사항 즉, 무선 통신의 불안정성, 이동으로 인한 연결 끊김 등의 문제와 배터리의 제약은 모바일 그리드를 구성하는데에 많은 어려움을 야기한다. 따라서 본 논문에서는 이러한 제약사항을 극복할 수 있는 환경적인 요소를 고려하여 학교나 회사와 같이 안정적인 무선통신 환경을 제공하고 베터리 충전이 용의한 네트워크 그룹을 가정하였다. 그리고 제한된 성능을 발휘하는 모바일 장치에서 독립적인 소규모 작업의 효율적인 수행을 위해 성능예측 기반 작업 스케줄링 기법을 제시하였다. 이 기법은 네트워크 그룹 내의 모바일 장치의 이용 패턴이 규칙적으로 나타내는 특성을 이용한다. 제안하는 스케줄링 기법에서는 하나의 네트워크 그룹의 성능을 그 그룹에 속한 모바일 장치들의 성능의 합으로 정의하고 시간에 따라 변화하는 모바일 장치들의 성능을 예측하기 위해 기존에 수집된 성능 정보의 통계를 이용한다. 그리고 본 기법은 그리드와 네트워크 그룹, 네트워크 그룹과 모바일 장치 사이의 작업 분배시 예측된 성능 정보를 이용함으로써 네트워크 그룹의 사용률을 높여 전체 작업의 최종 응답시간을 줄일 수 있다.

The purpose of this study is to compare the differences of the career development and the occupational view between giftedness in computer science and normal students in elementary school, so the results of this study provide assistance to the teacher for the direction and guidance on the career education of the giftedness in computer science in elementary school. This survey is based on 82 giftedness in computer science and 167 normal elementary school students. The questionnaires used in the study contain questions asking regarding the career development and the occupational view. The results of this study were as follows : First, according to the consciousness analysis result about career, the giftedness in computer science choose to be scientific technicians, the normal students choose to be artists. The both groups get career information from their parents, but they usually don't get career counseling from teachers. The education of giftedness in computer science does not contribute to changing their dreams, while normal students have no interest in computer science. Second, according to the career development analysis result, in comparison with non-gifted students, the gifted in information science had more success in all domains of career development. Third, according to the occupational view analysis result, the information science gifted students had higher meaningful rate than the normal students. Intrinsic domain' had higher meaningful rate among the subordinate domains, there is no difference in 'extrinsic domain' and 'incidental domain' between the information science gifted students and the normal students. Fourth, according to the correlation analysis result of the career development and the occupational view, there is a positive correlation in all domains of them. The high they are in the career development, the more they have the certain occupational view. Likewise, if they have the certain occupational view, they will be more successful in career development. Based on the findings of this research, the directing and guidance on the career education of giftedness in computer science in elementary school is same as the followings. We should educate parents regarding information about career for students who are under the influence of parents greatly and indicate them to apply to their children appropriately. In addition, for making them to have the positive image of the computer science, teacher should provide more information about the area of information and form various curriculums to induce more interests about computer science. We need to strengthen the career education for guiding the gifted to assist them to establish their own goal and realize them how to study and choose their career in the future. In school education field, it must develop and manage the definite and empirical program, not the career development program which is focused on only entrance into advanced school, to boost self-realization ability and the suitable career education program based on the correct understanding on giftedness in computer science. For this, through steady trying and research, teachers should be eater to develop the career education for students. Also, we have to implement the internal stability career education program, so it will help students to be aware of their job and career; therefore, students will be able to plan and prepare for their career in this rapid changing world.
