Knowing the learner's image of a subject-related occupation is good data for determining the direction of a teacher's teaching and learning. Existing drawing image analysis tools have the limitation that it takes a long time to analyze images and drawings of a scientist's appearance. The semantic differential method is a widely used method to analyze images of specific objects. However, research using the semantic differential method has the limitation of failing to reflect terms or factors that change over time by using the adjective pairs used in the initial study as they were in accordance with the research content. In this study, we use the semantic differential method to develop a tool to measure middle school students' scientist image and apply it to middle school students to discuss educational implications regarding the usefulness of measuring scientist image.

With increasing interest on scientists and the influence of science technology, their role in the modem society has been expanding. Scientists work in the laboratory as researchers, work in their expertise area as professionals, and work socially as social agents. Scientists are responsible to keep up the regulations during the research, and also are responsible for the results of the research. Therefore, there is a need of contemplation in terms of what their identity is and what their responsibilities are. Despite of this need, there hasn't been much discussion or education on the scientists social role or responsibilities as of now. This study purported to contemplate on the scientists role and responsibility, its qualification, and what it means to be a scientist as a social agent. Also the study further explored the efficient educational strategies and methods relevant to the contemplated issues.

서울대 사범대 화학교육과 백명현교수는 요즘 초분자를 이용해 새로운 작품을 만들고 있다. 백교수의 전공은 무기화학으로 초분자소재 화학연구에 심혈을 기울이고 있는데 이는 거대한 분자를 이용해서 초분자를 만드는 연구로 그녀의 연구결과로는 기억매체로 응용될 수 있는 강자성 물질의 합성에 중요한 단서를 제공한다는데에 의미가 있다. 백교수는 이 분자체를 이용해 분자 벽돌담과 분자 벌집들을 합성해냈고 그 모양의 꽃무늬 레이스 같다고 하여 이름을 꽃무늬 레이스 초분자 라고 붙였다.

To investigate how personality test items are understood by participants, their semantic representations were explored by Latent Semantic Analysis, In this thesis, Semantic Similarity Matrix was proposed, which contains cosine similarity of semantic representations between test items and personality traits. The matrix was compared to traditional factor loading matrix. In preliminary study, semantic space was constructed from the passages describing the five traits, collected from 154 undergraduate participants. In study 1, positive correlation was observed between the factor loading matrix of Korean shorten BFI and its semantic similarity matrix. In study 2, short personality test was constructed from semantic similarity matrix, and observed that its factor loading matrix was positively correlated with the semantic similarity matrix as well. In conclusion, the results implies that the factor structure of personality test can be inferred from semantic similarity between the items and factors.

우리 협회는 2004년 9월에서 10월까지 약 2달 동안 한국과학문화재단, 21세기한국생명과학발전연구회와 여러 출판사들의 후원과 협조로 문화소외지역(인구 15만명 미만)의 공공도서관 및 대학도서관을 대상으로 '도서관에서 작가/과학자를 만나다' 강연회 행사를 개최하였다. 우리 협회는 이번 사업을 통하여 ▲ 도서관을 통한 지역문화 활성화에 기여하고, ▲ 직접 만나기 어려웠던 작가/과학자를 직접 만날 수 있는 기회를 제공하여 지역 주민들의 독서 문화 진흥에 도움을 주고자 하며, ▲ 청소년들과 시민들에게 과학문화에 대한 이해를 높이고 자연과학분야에 대한 관심을 끌어낼 수 있는 기회를 갖고자 하였다. 본지 11월호 특집에서는 총26개 공공도서관과 1개 대학도서관 그리고 18명의 작가와 14명의 과학자가 참여한 '도서관에서 작가/과학자를 만나다' 행사를 돌아보는 의미에서 협회 사무국 담당자, 행사에 참여한 작가와 과학자, 도서관측 담당자, 출판사측 담당자의 글을 준비했다. 행사현장의 분위기와 사업추진 경과, 성과 등을 함께 나누어보기를 바란다.

The image of scientists that learners have has an important impact on science learning and on science-related career choices. The image of the scientist was mainly analyzed using the drawing analysis method. Drawing analysis has limitations on drawing, mainly analyzing the external image of scientist. Science teachers' images of scientists and their perception of science-related careers are important factors in students' science learning and science-related career choices. However, research on science teachers is lacking. Therefore, the purpose of this study is to investigate the usefulness of measurement tools by developing and applying a scientist image measurement tool through the semantic analysis method, and to discuss the educational implications of the research by investigating the image of scientists and science-related professions of secondary pre-service science teachers. The subjects of the study were 79 male and 55 female for a total of 134 students in the 2nd and 3rd grades majoring in science education at a teachers college. The results of the research show that the image measurement tool consisted of four components: 'ability,' 'evaluation,' 'activity,' and 'emotion,' in 24 items. As a result of applying the developed measurement tool to the secondary pre-service science teachers, the image of the 'evaluation,' 'ability,' and 'activity' elements of the scientist were high, but 'emotion' was low. There was no statistically significant difference according to gender. It is found that science-related career perceive them as 'hard,' 'professional,' 'smart,' and 'complex.' In particular, male students perceive themselves as 'hard and difficult' while female students perceive it as 'challenging and complicated'. Finally, we discussed the usefulness of using the image measurement tool of the scientists, the image of the scientists of the secondary pre-service science teachers, and the educational implications on science-related career.

지금까지 우리는 환상 단량체(cyclic monomer)를 이용한 macromonomer의 다양한 합성 방법론에 대해 고찰해 왔다. 리빙 개환 중합(iving ring-opening polymerization)이 좁은 분자량 분포 및 예견할 수 있는 well-defined 구조를 갖는 macromonomer들을 합성할 수 있는 최상의 방법임은 주지의 사실이다. 또한 이렇게 합성된 macromonomer들을 이용한 graft 공중합체의 합성은 이미 언급한 바와 같이 다방면에 사용되고 있다. 다음으로 중요한 점은 많은 과학자들이 과학적 용어(scientific term)의 사용에 있어서 사용자들에게 많은 혼돈을 주고 있다는 사실이다. 예를들면 macromonomer는 Macromer$^{(R)}$ 혹은 macromolecular monomer등과 같은 의미이지만 어느 한가지로 통일되지 못하고 사용되고 있는 실정이다. 덧붙이자면 macromonomer는 기능화된 고분자(functionalized polymer) 혹은 넓은 의미의 'telechelic polymer'의 범주에 속한다. 본래 telechelic polymer란 분자 말단에 두개의 반응성기를 갖는 고분자나 oligomer를 일컫는 말로서 기능성 고분자(functionalized polymer)의 범주에 속한다. 이러한 사실들을 고려해 볼때 macromonomer는 중합이 일어날 수 있는 반응성 기를 가진 기능성 고분자 혹은 telechelic 고분자이다. 또한 많은 사람들이 macroinitiator와의 상이점을 구별치 못하는 경우가 있다. 물론 macroinitiator는 보통 block 공중합체를 제조하는데 이용되고 있는 반면 macromonomer는 graft 공중합체 합성에 사용되는 고분자 또는 oligomer이다.

The purpose of this study is to investigate the meaning and process of scientific observation. Hence, this study reviewed and discussed meanings and process of scientific observation described in philosophy, the philosophy of science and science education. Major researches on scientific observation are focused on a characteristic and type of scientific observation behavior. These research can suggest what is the characteristic of observation facts generated by observer. But it cannot show what is the meaning and process of scientific observation, it should be provide to students. According to the result in this study, scientific observation is affected by observer's subjective factors, such as experience, background knowledge, interpretation(not inference) and observation skill. All factor are integrated as an intellectual framework, and it is able to be changed by the observed facts. On the other hand, inference is excluded on scientific observation, but it have constantly affect on intellectual framework through feedback. This study on scientific observation provides a scaffold in various activities of scientific observation to be provided to students.
