이 연구의 목적은 (가)학생들의 "공기중의 물"에 대한 직관적 견해와 그 특성들을 파악하여 기술하고, (나) 나이와 학습 능력의 증가에 따른 직관적 견해의 분포 및 변화 경향의 파악 및 기술(description)에 있다. 미국 텍사스주 중부에서 36명의 연구대상 학생들이 선발되었다(5-, 8-, 11-학년 및 대학교 학생 각각9명씩). 대학생들을 제외한 각 학년은 3명씩의 우수, 보통 및 열등 학생들로 구성되었다. 연구 방법은 현상에 대한 면담법(Interview-About-Phenomena)이 사용되었다. 대기 중의 물은 7개의 종속개념(수증기, 습도, 증발, 응결, 승화I과 II, 그리고 이슬점)으로 세분되어 조사되었다. 연구 결과 각 종속개념마다 3개에서 7개까지 여러 직관적 견해들인 파악되었다. 학년과 학습능력이 증가 할수록 학생들은 더 정교한 직관적 견해를 보유하고 있었다. 파악된 직관적 견해들의 재구성(restructuring) 또는 보다 정교한 (more sophisticated) 견해로의 변화는 종속개념에 따라 다르다. 직관적 견해들이 재구성되기 쉬움에 따라 종속개념들을 배열한 것을 "재구성 계열"(Restructuring series)이라 정의 하였으며 이는 다음과 같다. 수증기-습도-이슬점-응결-증발-승화 I과 II . 이 연구의 결과는 과학교수 전략 및 과학 학습교재의 고안과 개발, 과학교사 양성과정, 그리고 과학학습 평가 등에 활용되어져야 할 것이다.

Selecting an appropriate science instructional model for content or activities is crucial for good science teaching. However, teachers seem to be ill-prepared in selecting suitable models for their science class. The purpose of this study is to develop a procedure for selecting science instructional model appropriate for content or activities. Major science instructional models were selected and classified according to their characteristics. Models were categorized into two major groups : student-centered model group and student-assisting model group. In student-centered model group, experiential, discovery, and inquiry learning models were included. Conceptual change learning model and learning cycle were grouped into student-assisting model group. A learning model whose characteristics are mateched with those of the content or activities to be taught would be selected for instruction. The procedure developed was applied to the part of science textbook for 6th-graders. the result was compared to the learning models selected by experienced teachers. Inconsistencies were found among the models selected by teachers and the procedure. The procedure developed should be studied further and revised. The results of this study have many implications for improving in-service teacher education, science instruction, and the development of science instructional theory.

Portfolio assessment has many promising aspects for educating future-oriented elementary teachers. The purpose of the study is developing a portfolio system to enhance science teaching competencies of the pre-service,elementary school teachers. A portfolio system was developed based upon the experience of 1st, and 2nd administration of portfolio assessment. The portfolio system developed is for the lecture, "Science Education I" for sophomores at Chongju National University of Education. The elements of the portfolio system are objectives, portfolio forms, scoring rubrics, and portfolio display schedules. Portfolio forms are designed to give guidance and direction in developing evidence for students. They are also supposed to assist students' achievement of objectives. Most students were successful in completing portfolios. The number of outstanding portfolios was increased up to 41%. Many students complained the burden to complete the portfolios, however, many of them expressed their confidence about themselves and science teaching abilities after the semester.

A survey was carried out comprehensively to investigate the present status of science education in primary schools 496 teachers in 199 primary schools in Chungbuk area participate in the survey. They questionnaire used in this study included items regarding goals or objectives for science education, approaches for instruction, teaching-learning strategies, assessment for instruction, teaching-learning strategies, assessment for instruction, computer use in science classes students' activity and the status of experimental equipment or tools for science education. Items on science textbooks and the understanding of the 7th national curriculum were also included in it. The results based on the teachers' responses were summarized and provided in this paper and it showed practices of science education in Chungbuk area.

The purpose of the study is to investigate the effects of a portfolio system on elementary school students' science achievements and classroom environment. The participants were selected from seven schools located in central parts of Korea. Two classes were selected randomly at each school, and one class was assigned to experimental group and the other to control group. The total number of participants is 475. The research use pre-post test intact group design. Little difference is found in science achievement. However, statistically significant difference is found in classroom environment. The experimental group show meaningful gain in the sub-domains such as task orientation, equity, and teacher support. Considering that the portfolio system had been administered in relatively short period of time, it has high potential for the reform of science classroom.
풍진에 속발된 재생 불량성 빈혈 환자에서 동계 조혈모세포 이식 치험 1례

재생 불량성 빈혈의 원인으로 여러 종류의 바이러스들이 알려져 있지만 그 발병 기전은 잘 밝혀져 있지 않다. 풍진에 속발된 재생 불량성 빈혈은 문헌상 단 몇 차례만 보고되었다. 재생 불량성 빈혈이 일란성 쌍생아 중 하나에서만 발생하였을 때는 병인을 연구해 볼 좋은 기회가 된다. 14세 된 남아가 3개월 전 풍진을 앓고 난 후 중증 재생 불량성 빈혈이 발생하여 내원하였다. 입원시 풍진에 대한 IgG와 IgM이 양성 소견이었다. 4주간의 관찰에도 혈액 소견이 좋아지지 않아 일란성 쌍생아 형으로부터 과립구 집락 촉진인자로 가동화시킨 말초혈액 조혈모세포를 채취하여 환자에게 단순 주입을 시행하였으나, 단지 일시적인 생착을 보였다. Cyclophosphamide와 antithymocyte globulin으로 전처치 한 후에 동일한 공여자로부터 골수를 재취하여 시행한 이차 이식 후에는 현재 17개월 동안 지속적인 조혈 기능을 보이고 있다. 본 증례는 매우 드문 풍진에 속발된 재생 불량성 빈혈 환자로 전처치가 선행된 동계 조혈모세포 이식 후에서야 성공적인 생착을 보인 경우 바이러스에 의한 재생 불량성 빈혈의 병인에 있어서 면역학적 기전을 시사한다. Although various viruses have been implicated as causative agents for aplastic anemia(AA), the pathogenesis has yet to be elucidated. Only a few cases of rubella-associated AA have been reported in the literature. The development of AA in one of monozygotic twins provides an opportunity to postulate the pathogenesis of the disease. A 14-years-old boy presented with severe AA. Three months before admission, he contracted rubella during an outbreak. Both IgG and IgM for rubella on admission were positive. His blood counts did not improve over 4 weeks of observation. Simple infusion of granulocyte-colony stimulating-factor-mobilized peripheral blood stem cells from his monozygotic twin resulted in transient recovery. Second transplant with marrow from same donor after conditioning with cyclophosphamide plus anti-thymocyte globulin resulted in sustained hematopoietic recovery for 17 months. This case describes a unique patient of rubella-associated AA who showed a successful engraftment only after conditioning following syngeneic stem cell transplant, supporting the immune mechanism in the pathogenesis.
