  • 데이터 웨어하우스는 운영 시스템이 아닌 "경영층의 의사결정지원을 위한, 통합적, 시계열적, 주제 지향적, 비휘발성적인 데이터의 집합"으로 정의된다. 데이터 웨어하우스는 기업정보처리를 위한 기본적인 아키텍처로 데이터가 공급되었다고 해서 정보의 창조와 사용과 직결되지는 않는다. 데이터 웨어하우징 시스템은 데이터 공급이 아니라, 정보의 사용을 주목적으로 하고 있다. 현재의 항만공사 운영시스템인 Port-MIS에서는 데이터베이스 구성이 전체적인 데이터 아키텍처 하에서 구성되지 않고 업무별 데이터베이스, 목적별 데이터베이스 형태로 구성되어 있다. 이러한 점들 때문에 데이터베이스 확장에 한계가 있고 데이터 불일치 등이 발생할 수 있으며, 전사적 데이터 자산관리가 이루지기 어렵다고 볼 수 있다. 이에 본 연구에서는 항만공사의 운영을 위한 데이터 웨어하우스 구현 방안을 개념적 연구로 제안하였다.

  • This study explored ways to implement a competencies-based curriculum in schools by reviewing exemplary cases that have introduced Key Competencies (KCs) in the school science curriculum. Since the OECD redefined key competencies as 'what people should know and do in order to lead a successful life in a well-functioning society', many countries have emphasized the use of a competencies-based curriculum. Foreign and domestic classroom cases, which have used a competencies-based curriculum in science teaching, were collected and analyzed. Through open-ended interviews with teachers and principals, we investigated changes of teachers' professional knowledge and practice that were evident as a result of the implementation of competencies-based curriculum in science class. Foreign science teachers suggested ways to relate competencies-based curriculum and science curriculum including maintaining a balance between competencies-based curriculum and content-based curriculum. They also integrated KCs into all subject-based curriculums, gave priority to KCs over subject matter knowledge, and developed KCs through teaching science contents that students wanted to learn. On the other hand, Korean science teachers suggested reconstructing competencies-based curriculum by extracting common attributes from the existing subject areas. They also made KCs realized through content teaching, and developed various KCs within science contexts. Implications of the competencies-based curriculum for science teaching and learning were discussed at the end.

  • Korean civil and environmental organizations had selected and announced ‘The top ten pieces of news in the environmental field of the year’ on Dec. 2, 1999. This study investigated the possibilities that these could be used as subject matters of environmental curriculum and infused into the environmental textbook of secondary schools, referring to documents and internet materials. The top ten pieces of environmental news could be clarified as controversial topics. The locality was analyzed that 2 pieces occurred mainly in a specific area, 4 pieces in several areas and 4 pieces around all over the country. Most of them had the opposing partners as the federal and local governmental vs. civil organizations and people. Each of them could be used as subject matters for 7 to 13 contents domains of the 6th and 7th Korean environmental curriculum. The knowledge of most of them had related counterpart concepts to be infused into the ‘Environmental Science’textbook for the high school students. The results suggested that more concerns and efforts are needed to deal and use these controversial issues as real world problems of Korea in the environmental education practices

  • The Journal of the Korean Solar Energy Society is the first journal in South Korea that adopts wind energy as one of its subjects. Since 2000, more than 140 papers on wind energy have been published in the journal, which accounts for 8.5% of the total publication. However, in recent years, the number of published papers on wind energy has been decreasing steadily, and a reason for this decline is the significant dependence on a few specific institutions and authors. In this study, wind energy subjects were classified using the frequency analysis of the subject words extracted from the title, keywords, and abstract of wind energy papers using the text mining technique. In addition, the Korea Citation Index was used to perform quantitative level evaluation by subject and institution and to analyze the trends and characteristics of the wind energy field. Therefore, it was identified that in terms of the number of publications and citations, the main subject areas were resource/micrositing and policy/potential.

  • 인문학의 여러 분야에서 논의되고 있는 탈인간주의는 인간과 기계의 융합 경향 속에서 근대 인간관의 핵심인 '자율적 주체'의 운명을 문제 삼고 있다. 심리학은 19세기에 독립된 학문으로 성립된 이래로 인간을 자율적 존재로 보는 인문학적 접근과 인간을 결정된 존재로 보는 자연과학적 접근이 늘 병존해 왔다는 의미에서 이미 '탈인간의 심리학'이었다. 필자는 '자율적 주체'라는 관념이 우리가 목표지향적 행위자로서 살아가는 일상생활의 조직원리로서, 그리고 인간에 대한 인과적 지식에 의미를 부여하는 기본 개념틀로서 여전히 유효하다고 주장하였다. 그리고 문화와 문화교육은 과학기술이 인간의 목적합리성에서 벗어나지 않도록 성찰하고 조정하는 역할을 수행해야 한다고 주장하였다.

  • In this paper, we analyze what the components of mathematics teacher` knowledge are, and find that mathematics teacher need knowledge of three areas: subject matter knowledge, pedagogical knowledge, and pedagogical content knowledge. Studies of practicing teachers suggest that When teachers lack understanding in their respective disciplines, it inhibits them from providing students the best learning opportunities, but that a teacher possessing pedagogical content knowledge provides learners with multiple approaches into learning. Some teachers having sound knowledge of mathematics and students were able to respond appropriately to students' questions, design appropriate learning activities involving a variety of mathematical representations, and orchestrate mathematical discourse in the classroom. Thus, it appears that mathematics teachers' knowledge positively affect teaching and student learning..
