  • The importance of nanopore structures of carbons is shown in terms of interaction potential for various molecules including supercritical gases such as $H_2$ and $CH_4$. The key factors for adsorption of supercritical $H_2$ and $CH_4$ are shown for single wall carbon nanohorn, single wall carbon nanotube, and double wall carbon nanotube. The cluster formation of molecules is a key process for water adsorption on hydrophobic carbon nanopores. The X-ray absorption spectroscopic examination elucidates an explicit dehydration structure of ions confined in carbon nanopores.

  • The purpose of this study was to compare and analyse the subject organization and teaching units of middle school science curriculums and science textbooks, by studying the organization of subject matter and content scope and level of middle school science subject in South and North Korea. As a result of this study, the composition, scope, and level of content between middle school science textbooks in South and North Korea were similar. However, the study found that science education objectives, separated science curriculum subject organization, economical efficiency weighted format and organization of science subject matter, result-centered experiments, the enlightenment of Kim Ilsung and his son in North Korea science education were very far from the desirable direction of science education. Therefore, the view on level-based curriculum and organization of the science curriculum should be integrated, and preparation of student-centered organization of textbooks and expansion of science-technology-society content is needed before unification. And also, the united Korea science curriculum shouldn't simply compromise or neutralize between middle school science curriculum in South and North Korea. They should make a future-oriented plan for information and globalism society.

  • 본 연구에서는 2011년에 설립된 부산과학고등학교 별샘천문대에 있는 32인치 반사망원경을 비롯한 여러 천체망원경들을 간단히 소개하고 관측을 통해 성능을 분석하여 향후 교육과 연구에 활용할 수 있는 기초 자료를 제공하고자 한다. 관측기기들의 기계적인 특성을 분석하기 위해 가대의 추적 특성과 정밀도, 지향특성 등을 조사한다. BVI 표준성 관측을 통한 표준계 변환 결과를 제시하고, 한계등급에 대해 고찰한다. 이를 통해 32인치 주망원경과 기타 보조 망원경 및 교육용 기자재를 활용하여 관측할 수 있는 주제를 모색하고 그 한계를 제시한다.
