  • This study was aimed to understand the structures of preservice secondary school teachers' alternative conceptions on radioactive isotopes in the interior of earth. The structure of their conceptions were analyzed by the suggestions of Niaz (1988) based on the Lakatosian frameworks. The survey was carried out on a group of seventeen students who were major in science education. The research method was open-ended written questionnaire. The results of this study show that students had apparent alternative conceptions. The high temperature and pressure' explanation for radioactive decay in earth's interior had most import effects on their alternative conceptions. It was also intended to survey their conceptional change by our teaching strategies of the philosophy of science in order to construct science concepts.

  • In Korea the musical was granted very close an art however recently it is rapidly take the position a new trend of the mass culture industry with some of promoted lifestyle due to increased income and with spreading consumer culture of well-being. This study is to consider the musical as a way of OMSU to observe how to produce the musical the with the original one that recorded as the best animation program with highly broadcasting rate as it is broadcasted on TV. It is belongs to a category of musical or a performance, has a good feature of children's program with arranging the broadcasting. Through this study, developing performance art to OSMU, it wishes to utilize people that produce the performance applying the contents of animations and cartoons, to make value added This study is for presenting an effective way of OSMU, with studying and researching the production process of the musical . The original source the cartoon and animation is transferred to a musical with a technical feature of digital audio-visual, with characterizing to an attractive musical characters from the original characters, and with humorize twisted story structure based on the basic storyline.

  • The basic strategy of OSMU(One-source Multi-use) in digital image is a marketing that applying one source to other genres for leverage based on that cross-referencing in different genre enabled that one material(one-source) has synergy effect when reproduced to various products(multi-use) as cultural sources are available through on-line and digital format. Recently, according to the characteristics of culture industry with Window Effect, many culture contents such as movies, games, animations and characters are carefully planned at its design stage to get the maximum effect. Especially, the fact that one leading-trend source makes it easier to produce additional products with the least cost is observed and it enables organized management which resulted in low marketing and PR cost. This paper confirmed that OSMU strategy in Korea mainly get started from online to offline comparing to Japan and USA.

  • A self-structured neural network algorithm that finds optimal fuzzy membership functions and nile base to fuzzy model is proposed and a fuzzy-neural network controller is designed to get more accurate position and velocity control of wheeled mobile robot. This procedure that is composed of three steps has its own unique process at each step. The elements of output term set are increased at first step and then the rule base Is varied according to increase of the elements. The adjusted controller is in competition with controller which doesn't include any increased elements. The adjusted controller will be removed if the control-law lost. Otherwise, the controller is replaced with the adjusted system. After finished regulation of output term set and rule base, searching for input membership functions is processed with constraints and fine tuning of output membership functions is done.

  • This paper presents the overall attributes of the current IAEA programs and their future prospects in the arena of applications of radioisotopes and ionizing radiation, thus dealing with the demand to achieve a condensed understanding of the Agency's programs for an effective and efficient deployment of the respective national R&D projects in Korea. The considerable and beneficial advantages of a participation in the IAEA programs have been reviewed and their immediate relevance has been emphasized. A strategic approach for the enhancement of an active participation in the program and its efficient implementation has also been established. It is anticipated that the proposed recommendations such as the long term strategy and the applicable guidelines will be useful in formulating a nuclear policy for the further development of the international cooperative projects in the future.

  • This paper presents stabilization and position control of the Inverted-Pendulum system with cart by using Evolution Strategies that is one of the Evolutionary Computation and is effective in searching real number. The control input of the Inverted-Pendulum is the element of chromosome corresponding to the divided space of Inverted-Pendulum state variable x, x, 0, 0 . In general, the larger the length of the chromosome is, the longer the time of evolution to search optimal solution is. So in this paper, we propose a scheme that reduce the state space by half by taking the method, that is, converting only the sign of the control input without obtaining separately for the symmetrical sections of the Inverted-Pendulum to improve the speed of Evolution, and improved the efficiency of the entire system in addition to the improvement of the chromosome's evolution time by carrying out the chromosome's evolutional process by two steps one of which is that cart is positioned near the control point and the other cart is positioned far from that point. We propose another method that is Neural Network-Evolution StrategiedNN-ES) Controller. We verify the effectiveness of the proposed control scheme by computer simulations.

  • 뮤지컬 문화공연 시장 규모의 확대로 인해 다양한 뮤지컬 작품을 관객들은 원하고 있으며, 이에 뮤지컬 문화공연 콘텐츠의 OSMU의 활용이 중요하다. 이러한 활용방안으로 첫째, 뮤지컬 문화공연 콘텐츠는 역사, 설화, 문학, 국악, 영상(드라마), 영화, 무용, 댄스 등의 다양한 소스(작품)들의 상호 조합으로 새로운 멀티 유즈로의 활용이다. 따라서 뮤지컬의 문화공연 콘텐츠의 OSMU의 활용을 위해서는 다양한 뮤지컬 소재의 발굴과 함께 문화공연 작품의 창작 활동이 중요한 것으로 생각된다. 둘째, 이미 작품화 된 뮤지컬 문화공연 콘텐츠는 다양한 부가가치 가지므로 공연 관련 상품을 가공, 판매를 하는 OSMU로의 활용이다. 이에 공연 기획 단계에서부터 부가 상품 판매에 대한 체계적인 마케팅 전략을 별도로 수립, 티켓 판매만이 아닌 다양한 부가 상품 개발을 통해 뮤지컬 문화공연 콘텐츠를 다양한 상품의 형태로 재 판매하는 OSMU 활용 방안이 필요하다.

  • 건유기에서 비유기로의 이행기는 젖소에서 위험률이 높은 시기이고 이 시기에 가장 큰 문제가 될 수 있는 것이 유방염이다. 환경성 세균들이 분만 전후기에 가장 문제가 될 수 있는 병원체이다. 대장균군에 속하는 세균들은 경산우에서 심각한 감염을 일으킬 수 있고, 처녀우의 경우는 coagulase-음성 포도상구균에 감염될 가능성이 높다. 분만 전후기 중에는 호르몬이나 기타 요인들로 인해 젖소들의 면역상태가 다소 억압된다. 성공적인 유방염 방제 프로그램은 건유우, 분만우, 및 처녀우의 관리에 초점을 맞춰야 한다. 청결하고 안락한 환경, 적절한 사료공급, 비타민과 미량 원소가 함유된 적절한 사료의 보충이 유방 건강을 유지하는데 필수적이다. 건유 시작할 때 유두관의 폐쇄를 강화하고 케라틴 마개가 형성될 때까지 유두 끝을 세균으로부터 보호해 줄 전략들을 사용해서 분만 후의 유방염 감염 위험을 감소시켜야 한다. 건유기 치료는 상당히 성공적으로 이용되어 왔지만 전체적으로 실시하기 보다는 선택적으로 치료하는 접근법이 권장된다. 환경성 유방염에 감염될 위험이 높은 우군에서는 항생제 이외의 접근법이 건유기 중의 신감염 예방을 위한 유용한 도구가 될 수 있다.
