Though the nuclear fusion system has been fused into hydro-nuclear based on thermodynamics by tokamak system, there has been no success story. Because it's impossible to confine high temperatured plasma long Time actually. New nuclear-fusion-system using this nuclear-fusion-method will gather toroidal-magnetic-field by putting Core Block(C shaped torus iron) and toroidal-aluminium coil into toroidal magnetic-field-aluminium. That will arrange the nuclear-fusion-route on a gap fallen out by a part of cut torus-core and mkee the toroidal-an electric-current flow and electrolyze the fusioned-material (an electrolyte) into troidal-electrocity. That consists of troidal-magnetic-fild coil, toroidal-coial fusioned- material, series circuit. So toroidal-electocity will be changed into filament-electrocity and be introjected into fusioned-material. In a sapce on filament-electrocity, the magnetic inhaling-powr will enlarge to input-electrocity outside. This will exceed the Coulomb force and reache the nuclear-fusion. By this phenomenon there be quantity-loss. By this process I could confirmed that Einstein euation$(E=mC^2)$ releases into thermal energy.

하천에서 유사량 자료는 하천의 이·치수 목적으로 활용할 수 있는 기본 자료중 하나로서 하상 변동 예측, 저수지 퇴사량 추정, 하도 계획과 설계, 유사조절 계획 수립 및 기타 구조물 등의 영향 평가 등 다양하게 활용할 수 있다. 본 연구에서는 신뢰성 높은 유사량 자료를 생산하기 위하여 국가유사량관측망 중 27개 지점에 대하여 유사량의 측정 및 특성분석을 수행하였다. 유사량 측정과정은 사전조사, 현장측정, 실험실분석, 모형적용(총유사량 산정) 단계로 구분할 수 있다. 사전조사 단계에서는 현장관련 정보를 수집하여 현장측정 계획 및 현장 안전대책을 수립하고, 현장측정 단계에서는 사전조사 단계에서 수립한 계획을 바탕으로 유사량을 측정하였다. 유사량 측정시 측선은 ISO 기준 이상의 5~7개로 측선을 나누어 측정하였고, 측정장비는 D-74, DH-48 부유사 채취기를 이용하여 왕복수심적분법으로 수행하였다. 실험실분석은 한국수자원조사기술원 유사량 실험실에서 채취시료에 대한 농도, 레이저회절법을 이용한 입도분석, 하상토분석(체분석), 비중실험을 수행하였다. 총유사량 산정을 위한 모형적용 단계에서는 수정-아인슈타인법(Modified Einstein Method)을 적용하였다. 또한, 유량-부유사량 농도 변화양상과 부유사량 특성 분석을 이용한 부유사량 측정결과를 평가하였고 각 지점의 부유사량특성을 잘 나타낼 수 있는 지수식(Q_ss = aQ^b)을 이용하여 유량-부유사량관계곡선식을 개발하였다.

The image of science is one of the recurrent topics in science education research. In particular, we believe that students' images of Doing-Science-Well could be used for identifying not only students' perceived goals of science learning, but also practical guidelines of effective science teaching. In this study, the students' images of Doing-Science-Well were investigated with the following two research questions: (i) what are student's images of Doing-Science-Well?; (ii) in what contexts do students perceive that someone is doing science well? Thirty seven students in a high school in Seoul, Korea were asked to write their personal experiences by which they realized that someone was doing science well. The main results of the study are the following: Firstly, the images of Doing-Science-Well could be categorized into 'Einstein type', 'Socrates type', 'MacGyver type' and six more types. Secondly, with regard to contexts, students tended to realize that somebody is doing science well in terms of two kinds of contexts: 4 physical contexts and 6 psychological contexts. The findings led us to develop a frame of judging Doing-Science-Well, which combines the types and two kinds of contexts. The frame illustrates the multiplicity of the images of Doing-Science-Well.

This study was to gain a suggestion how to educate the science gifted student and manage the science gifted education center by analyzing the science gifted student's perception of the science, scientist and vocation. One seventy and eight science gifted students were involved in the questionnaire to investigating the perception of science, scientist and vocation. As the results, many of science gifted students thought the convenience as the positive aspect of science and the environmental pollution as the negative aspect of science. Science gifted students considered most scientists a diligent person, researcher and what's more, they are careless about home. They suggested much more of foreign scientists like Einstein, Edison, etc. than Korean ones as respectable scientists. Scientist is a major vocation that they want and know in the science area, while some students want to be a doctor, occurred to science singer. The mystery, difficulty, complexity, scientist, etc. occurred to science gifted students when they heard the ‘science’. According to the results, there are in need of the new educational programs for the science gifted students and science gifted education center. One of the aims of the science gifted education center is the judgment and cultivation of the science gifted student. Therefore, the science gifted student to be educated to improve positively the images of science and scientist. In addition to, they should get a concern about the vocation in science area and to be a famous scientist.
