This study intended to examine the differences through comparative analysis of the illustrations in the 3rd - 6th grade elementary science textbooks. The analysis of the types and illustrations in the Korean and American textbooks revealed that the textbooks of both countries provide many photographs and illustrations, so as to deliver data mainly in the form of realistic illustration. In Korean textbooks, pictures and cartoons were mainly used with photographs to guide the students into experiments and to enhance their interests and curiosity. In contrast, the American textbooks place more emphasis on diagrams and photographs to train the students in analyzing and interpreting data. The Korean textbooks should place more emphasis on the diagrams in order to encourage elementary school students to analyze and interpret the given data. As a result the addition of more diverse forms of illustrations and the re-organization of illustrations according to the topic should be considered in future Korean textbooks.

In this study, we collected teachers' opinions with regard to the effects of the instruction using analogy generation, the disadvantages of the instruction, the problem-solving methods of the instruction, and the teacher's role in it, and accordingly tried to investigate its effectiveness with the analysis of students' academic achievements and motivation, and through the student's interview, after applying the activities of creating generated analogies, finding the difference between the objects and comparisons, and presenting new-known genetics concepts as the students themselves generated analogies. As a result of a teachers' workshop on instruction using analogy development, it was expected to have a positive effect on students' understanding of scientific concepts in genetics, which were found to be difficult for students to understand in learning biology. Students found analogy examples for concepts in genetics in daily life, compared their analogs to those of peers, and examined inconsistencies between targets and analogs through the process of discussion, which finally led to their correct perception of scientific concepts in genetics. In addition, instruction using student-generated analogies proved to have a more positive effect on improving academic achievement and motivating learning, compared with traditional expository instruction.

The purpose of this study is to develop program that take a genuine interest in science and motivate students to keep up their study for science gifted children of start period. In this study, we develop and apply the program about sinking and floating for elementary science gifted students, and analyse degree of conceptual change. Students' prior knowledge is analysed for developing the program, and each step is settled about concept of density and buoyancy. Conceptests are arranged into step by step, and we apply the program to 26 science gifted students of 6th grade elementary school. We compare a percentage of correct answers of pre-test and post-test and evaluate Hake gain for analysis of degree of conceptual change. As a result, science gifted students' concepts are changed effectively into scientific concepts by program based on peer instruction for gifted students of start period. And they evaluate the program is novel and useful, also they can be motivated by the program.

The purpose of this study is to investigate the perception of the mothers of science gifted in respect to giftedness compared to the "Scale for Rating the Behavioral Characteristics of Superior Students-R(SRBCSS-R)". For that, a survey of 18 mothers of elementary school science gifted and 32 mothers of middle school science gifted was conducted in relation to giftedness. The words and frame of this survey were analyzed using the Semantic Network Analysis. The results are as follows : The mothers of Elementary school science gifted perception were found to have a connected giftedness with reading, science, making something, etc.. On the other hand, the mothers of middle school science gifted perception were found to have a connected giftedness with problem, solving problem, mathematics, etc. in words analysis. The mothers of Elementary school science gifted have a strong connection with category on creativity, motivation, etc.. On the other hand, the mothers of middle school science gifted were more inclined towards the category on learning, motivation, etc. in frame analysis. That is to say, the mothers of science gifted are perceptive about giftedness respect to some elements as the "Scale for Rating the Behavioral Characteristics of Superior Students-R" on the giftedness. Therefore, a correct understanding about giftedness in respect to the mothers of science gifted is required and parent education is needed for appropriate science gifted education.

This study examined 39 elementary teachers' perceptions on the frontier science teaching and their teaching efficacy. The results showed: elementary teachers were interested in and were well aware of the importance of the frontier science in human life and in this society. They also agreed with the necessity of teaching frontier science in elementary school. They, however, had perceptions that frontier science may not be appropriate for the level of elementary students. Moreover, the poor educational environment may act as constraints for frontier science teaching. The change of elementary teachers' teaching efficacy(t=-13.67, p<.01) was statistically significant after their participation of developing STEAM program on frontier science and practicing its lessons.

각 부처에서 관리되고 있는 국가R&D정보는 범부처 공동활용을 위하여 국가과학기술지식정보서비스(NTIS) 체계를 통하여 유통된다. 그러나 부처별 연구관리전문기관에서 NTIS로의 단방향성 R&D정보 유통체계로 인하여 부처별 전문기관에서 관리되는 R&D정보와 NTIS에서 관리되는 R&D정보간 데이터 불일치 문제가 발생한다. 그러므로 본 논문에서는 국가R&D정보의 관리현황 및 문제점을 분석하고, NTIS와 부처간 국가R&D정보의 동기화를 위한 국가R&D정보 유통체계 개선 프로세스를 제안한다.

All over the world, the number of internet users has been increasing rapidly. In the middle of this rapid increase, there is Avata, which is popular to both adults and children by providing motivation and self-satisfaction. Therefore, the current study tried to find whether an instruction using Avata for the purpose of motivation has an effects on students' achievement among 6th graders. the results showed that the students' achievement in Language Arts, Mathematics, Social Study, and Science were improved significantly.

소노루미네센스(SL)현상은 액체 내에서 초음파에 동기화되어 진동하는 미소기포$~10\mu\textrm{m}$)가 수축할 때 기포내부의 온도가 고온이 됨에 따라 기포중심으로부터 빛이 나오는 현상을 말한다. 단일기 포가 초음파에 가진 될 경우 그 스펙트럼이 X선에 가까운 것임이 밝혀질뿐더러 촉매물 질의 개발이나 활성화, 고분자 합성뿐만 아니라 용액 내에서의 불순물 제거 등에 대한 응용의 가능성이 속속 발견되자, 현재 과학계뿐만 아니라 일반 매스컴에서도 화제의 대상이 되고 있다. SL현상은 원자당 $10^{11}eV$ 에 해당되는 초음파 에너지의 파장이 0.19.mu. 이하인 X선, 즉 6eV 이상의 광자에너지로 증폭됨에 따라 기포수축시 기포내 가스의 온도가 수만 도에 이르는 것, 레이저에 상응하는 광펄스 폭(50 ps)과 초음파에 동기되어 현존하는 최상의 수정시계에 필적하는 SL펄스의 규칙성, 기포수축시의 $10^{10}W/m^{2}$에 해당되는 열의 방출과 10억분의 수 초 동안에 $10^{4}K$의 고온상태에서 200K 정도의 저온상태로 바뀜에 따른 급격한 냉각속도 등 으로 특징지어질 수 있다. 이 글에서는 현재 실험을 통하여 알려진 SL에 관한 현상의 특징과 응용에 대해 구체적으로 기술하였다.

Purpose: This study was to identify the attributes, antecedents, their consequences, and empirical indicators of rehabilitation motivation in rheumatoid arthritis patients. Methods: Walker and Avant's method was used to analyze the concept. Articles published after 1990 were searched in Medline, CINAHL, NSDL, and RISS databases using "rehabilitation", "motivation" and their combination as keywords. Results: The attributes of rehabilitation motivation are: 1) certitude and trust toward rehabilitation treatment; 2) confidence in the rehabilitation process; 3) efforts and commitments to achieve health goals; 4) psychological needs to act toward health recovery. Its antecedents include: 1) rights of self-determination; 2) goal setting and goal-oriented attitude; 3) personal needs; 4) getting rewards; 5) social and family support; 6) professional behavior of healthcare providers; and 7) least risks or costs for actions taken. Conclusion: The study results could be used as a conceptual framework for developing tools to measure the motivation of rheumatoid arthritis patients.
