The purpose of this study was to examine the effects of children's role play by animatino on self-concept formation, The subjects of this study were 20 children of a kindergarten located in Gunpo City. the mean age were 5.5 years. Children were assigned to the study group and the control group. The children in the study group had role play of which the main themes were positive self-comcept formation but the children in control group did not have any role play by animation. The result showed 1. Role play by animation influenced on children's positive self-concept. 2. There was a difference in self-concept test score: The self-image attitude to the kindergatrten and attitude to the group of peer. Role play by animation influenced on the self-image and attitude to the group of peer. But attitude to the Kindergarten score was not increased significantly. 3. Role play by animation influenced on chikren's catharsis of emotion.

This paper discusses issues on the disign and implementation of real-time automatic speaker verification system, as well as the performance analysis of the implemented system. The system employs TI's TMS320C25 digital signal processor TMS320C25 and high speed SRAMs. The system is designed to be used stand-alone as well as via hand-shaking with IBM-PC. The speech parameters used for speaker verification are PARCOR and LPC-cepstrum coefficients, and the employed decision logics are those based on the generalized weighted distance comcept. The implemented system showed the performance of 5.3% error rate for the PARCOR coefficient, and 4.7% error rate for the LPG-cepstrum coefficient.

본 연구의 목적은 사용목적 및 지원양식 등이 상이한 개념도 작성도구들을 비교 분석하고, 단점을 보완하여 컴퓨터기반 협력학습을 적절히 지원할 수 있도록 새로운 지원도구를 개발하는데 필요한 시사점을 제시하는 데 있다. 이를 위해 대표적인 개념도작성도구(Convince Me, Knowledge Forum, Cmaptools, Mindmeister, Belvedere)를 선정하고, 도구의 사용목적 및 설계원리에 대한 선행문헌 분석을 실시하였다. 이후 휴리스틱 평가와 F.G.I.를 통해 전문가들의 다양한 의견을 수렴하여 효과적인 컴퓨터기반 협력학습을 지원하기 위한 개념도 작성도구 설계 원리에 대해 논의하였다. 분석결과, 대부분의 개념도 작성 도구는 커뮤니케이션 기능은 지원하고 있었으나 조정과 협동차원의 지원은 미비하였다.

One of the prime objectives of school science is to help the children learn science concepts and conceptual schemes that will help them understand and interpret their environment. One of the basic scientific concepts is 'Change -everything existing in universe is changing always'. The purpose of this study was to investigate the characteristics of elementary and secondary students' conception of change. The subjects for this study were 489 students in Korea; 111 fourth graders, 95 sixth graders, 140 seventh graders and 143 ninth graders. Four items - mountain, river, ground, sea -were used for investigating students conception of change because representing the nature world in elementary and secondary level. The subjects were asked to check whether each item was changing and to explain each their check. Students' explanations were classified by whether they were sound understanding geologically, or not. The rate of responses that each item was changing was compared by grades and the rate of geological explanations was also compared by grades. Because students' conceptions of change might were effected by time scale, the additional questions that asked students whether the present status of four items were equivalent to the that of several points of time. As a result, the rate of scientific answers and patterns of explanations were similar by grade and the rate of geological understandings was relatively low. The frequencies of concept of change were more dropped as the point of time was closer to present.
