  • We have examined the perception of teachers and students in elementary schools toward the frontier science and analyzed corresponding contents in science textbooks in Korea and the U. S. in order to promote a good guidance for the frontier science education. We prepared separate questionnaires for teachers and children, respectively, and analyzed the responses obtained from 244 teachers and 1,000 students in five elementary schools. For the analysis of how to introduce the frontier science, we investigated textbooks such as Science, Society and Practical Arts of Korean elementary school, and an American science textbook published by Scott Foresman. This study revealed that teachers are well aware of the importance of the frontier science, however, they are inactive in conducting the subject in class rooms because of their insufficient scientific knowledge and poor environment for teaching. It has been found that children had strong interest in the frontier science, however, opportunities to learn the topic are not properly provided. The frontier science m the American science textbook turned out to be more systematically introduced than that in Korean ones.

  • 초등교사 39명을 대상으로, 첨단과학기술 교수에 대한 인식 및 교수효능감의 변화를 조사하였다. 초등교사들은 첨단과학기술에 대하여 관심이 있고 일상생활 속에서 첨단과학기술의 중요성을 인식하고, 또한 초등학교에서의 첨단과학기술 교육의 중요성 및 필요성에 대해서도 공감하고 있는 것으로 나타났다. 그러나 초등교사들은 첨단과학기술 교육의 과학학습 동기 유발과 과학 분야의 진로 지도 등 유용성에 대하여 확신하지 못하는 것으로 조사되었다. 특히 초등학교 수준에서 첨단과학기술 교육의 적합성에 동의하지 않았다. 또한 현재 초등학교에서 첨단과학기술을 가르칠 환경 조성이 필요하다고 인식하고 있었다. 첨단과학기술 STEAM 프로그램의 개발 및 적용 후의 초등교사의 첨단과학기술에 대한 교수효능감 변화는 통계적으로 유의한 차이가 있었다(t=-13.67, p<0.01).

  • With conventional mass spectrometry (MS), ions are separated according to mass/charge (m/z) ratios. We must speculate the z values to obtain the m values. Superconducting tunnel junction (STJ) detectors can solve this problem, and true mass spectrometry becomes possible instead of m/z spectrometry. The STJ detectors were installed in MS instruments with a variety of ion sources. As an example, we report fragmentation analysis of a non-covalent protein complex of hemoglobin.

  • The challenge of predicting the Japanese coastal ocean motivated Frontier Observational Research System for Global Change (FORSGC) and the Japan Marine Science and Technology Center (JAMSTEC) to start a multiyear observational programme in the upstream Kuroshio in November 2000. This field effort, the Kuroshio Observation Program (KOP), should enable us to determine the barotropic and baroclinic components of the western boundary current system, thus, to better understand interactions of the currents with mesoscale eddies, the Kuroshio instabilities, and path bimodality. We, then, will be able to improve modeling predictability of the mesoscale, seasonal, and inter-annual processes in the midstream Kuroshio near the Japanese main islands by using this knowledge. The KOP is focused on an enhanced regional coverage of the sea surface height variability and the baroclinic structure of the mainstream Kuroshio in the East China Sea, the Ryukyu Current east of the Ryukyu's, and the Kuroshio recirculation. An attractive approach of the KOP is a development of a new data acquisition system via acoustic telemetry of the observational data. The monitoring system will provide observations for assimilation into extensive numerical models of the ocean circulation, targeting the real-time monitoring of the Japanese coastal waters.
