The previous study showed a large variation in performance within the queries and suggested that characteristics of queries cotribute to retrieval performance. Three attributes, specificity, complexity and recency were used to analyze the different results within queries. The result showed that subject searching retrieve more relevant documents for a Query with low specificity than a query with high specificity and that queries from the doctoral students' dissertations were specific queries with high specificity.

과학기술의 사회적 역할과 책임 확대, 기술개발을 통한 실질적인 문제해결이 강조되면서 국가 사회적 문제해결과 국민생활 전반의 삶의 질 제고를 위한 R&D 정책과 관련 사업에 대한 투자가 확대되고 있다. 정부가 사회이슈 해결을 위한 과학기술의 정책적 지향을 명확히 하면서, 출연(연) 역시 기존의 경제성장 견인과 성장동력 창출 중심의 기능에서 사회문제의 선제적 해결과 공공성 확장을 위한 출연(연)의 역할 수행을 요구받고 있다. 출연(연)은 공적임무 기반을 확대함으로써 국민들의 삶의 질 제고에 실질적으로 기여하겠다는 실천방안을 제출하는 등 다양한 모색과 자생적 혁신을 꾀하고 있으나, 연구자 연구현장의 수용성 문제와 출연(연)이 갖는 여러 특성과 맞물려 기대에 부합하는 변화의 폭과 속도를 내지는 못하고 있다. 본 발표에서는 출연(연)의 R&D환경과 사회문제 해결형 연구사업 현황을 살펴보고, 사회문제 해결을 위한 ETRI의 추진내용과 연구자 기술공급 중심의 경향성을 보완하기 위한 노력들을 소개하였다. 또한 출연(연)의 특성을 기반으로 전략적 투자와 효율적 운영, 성과의 확산 측면에서 사회문제 해결형 R&D 활성화를 위한 시사점을 제시하고자 한다.

Using information mapping methodology we will discover which of the multitude of information sources, services and systems used by corporation are actually resources and which are less important, redundant, or unnecessary. The discovery process of information resources will illuminate problems and opportunities related corporation's strengths and weeknesses in information quality, accessibility, performance, use, and effectiveness.

By PISA 2007, TIMSS 2011, Korean high school students had high academic achievement to science and mathematics, while they had low attitude. Prospective college students are increasingly avoiding natural science and engineering. Moreover, the opportunities to learn to computer science in middle and high school are disappeared rapidly. The necessity of STEAM program based on Physical computing arise under these situation. Therefore, we developed STEAM program and studied the effects of the program in 2012. The result showed that students' scientific interests and attitude, scientific problem solving ability, scientific creative problem solving ability, personality test for children, and satisfaction of school life were enhanced. This study is follow-up study for the same students who improved every domain of the measurements. They were administerd pre-test at start of 2012, post-test at end of 2012, and delayed post-test at the end of 2013, on same test. The result of the study showed that only attitude to Scientific Inquiry was enhanced, but there was no significant result on the other domain of the test in comparison with start of 2012. But this result demonstrate the effect of STEAM education conversely.

The Science Gifted Education Center of Chongju National University of Education used the chemical experiments for selecting gifted children in the area of science. There are two kinds of experiments, 'the observing the dissolution of cube sugar (Exp1)' and the guessing the concentration of solutions (Exp2)'. Students basic skills of observation, problem recognition and the ability using the models were verified through Exp1. Exp2 was used to verify the practical problem solving skill of children. Besides, the affective facts of the interests, adhesive power of the problems were evaluated through the teacher abservation. The evaluation using experiments turned out to be valuable for the identification of the gifted children who have the creativity, originality, and fluency in the field of science.

The study aims to run a 'Process-based Evaluation' and find out its effectiveness in science classes for prospective elementary school teachers. The Process-based Evaluation performed in this study was performed during unit classes and scored when significance was recognized in the student's learning behavior. The conclusions based on the results of the study are as follows. First, students scored an average of 3.6 points on whether the process-oriented assessment conducted during class was appropriate as an assessment. Second, on the basis of the assessment presented by the students, the main positive content is "assessing the process, not the outcome", "contributing positively to class participation" and "promoting accident activities". Third, the negative contents of the assessment grounds presented by the students include 'lack of objectivity in evaluation methods and results', 'the individual tendencies of students are involved in evaluation results' and 'poor learning effects of the textbook knowledge'.

In recent years, parents of students and government have been taking a growing interest in education for the gifted students and there are many research reports about the gifted education. Most of the reports, however, focuses on the conceptional feature of the gifted education program such as organization, operation, management, evaluation, etc,. In other words, there are very few researches on instructional materials for gifted students even though the materials is a critical factor for successful education programs. So, this paper introduces a lecture notes used in a personal education for gifted students to contribute in developing education contents in computer science area. The instructional materials titled as "The Necessity and Application of Matrix in Computer Science" is based on linear equation to usher the students into creative problem recognition and groping for solutions. Also, the instructional materials is useful for students to understand the tight mathematics-computer science relationship and the basic concept of liner algebra.

The purpose of this study was to investigate students' views on the scientific model and to compare their views by grade, gender, and achievement. Relationships between students' views on the scientific model and epistemological beliefs were also investigated. Participants were 137 8th- and 112 11th-graders in Seoul. The results indicated that the students' views on the scientific model, on the whole, were adequate except the items concerning the 'models as exact replicas'. Male students or high-achieving students had more adequate views on the scientific model than female students or low-achieving students. However, there was no significant difference between 8th- and 11th-graders. In correlation analysis, students with inappropriate views on the scientific model were found to have traditional epistemological beliefs.
