본 연구의 목적은 중등학생들의 과학의 본성 개념을 측정하는 도구를 개발하고 예비 투입을 하는 것이다. 이 조사 도구는 넓은 영역의 과학철학적 주제를 담은 24개의 선다형 문항으로 구성되어 있으며, 이 도구의 진술문과 선택지는 다양한 과학철학적 관점을 분석하여 만들어졌다. 이 도구 속의 주된 과학철학적 체계는 귀납주의, 반증주의, 그리고 상대주의이다. 이를 구분할 하위 주제는 구획의 기준, 과학적 변화 양상, 과학적 지식의 인식론적 지위, 그리고 과학적 방법이다. 또한 본 연구자들은 과학의 본성에 관련한 넓은 주제에 대한 학생들의 개념을 측정하고 해석하는 새로운 방법을 제안하고 있다. The purpose of this study was to develop, field test an instrument to assess secondary school students' conceptions of the nature of science. The instrument named Philosophical Perspectives Probe(PPP) is a pool of 24 multiple-choice items that address a wide range of philosophical topics of science. The statements and the choices of this instrument were derived from an analysis of various philosophical positions. The main philosophical systems of the instrument are inductivism, falsificationism, and relativism, respectively. Major distinctions depend on the issues of the criteria of demarcation, patterns of scienctific change, epistemological status of scientific knowledge, and the scientific methods. The researchers also offer teachers a new way of assessing and interpreting their students' conceptions on a wide variety of topics related to the nature of science.

본 연구에서는 중학교 과학교사들이 일련의 “카드 놀이” 활동을 통해 자신의 과학철학적 관점을 확인하였다. 본 연구의 피험자는 1997년 경상남도 중학교 실험 연수에 참여한 156명의 과학교사들이며, 3시간에 걸쳐 활동을 수행하였다. 본 연구의 결과, 피험자들은 전공, 성별, 또는 경력에 관계없이 귀납주의적 견해가 강하다는 것을 알 수 있다. 또한 합의 형성 과정을 통해서 중도적 견해를 도출하기 보다, (a) 구획의 기준과 (b) 과학의 변화 양상은 극단적이 귀납주의로 회귀하였으며, (c) 과학적 지식의 인식론적 지위는 상대주의로, (d) 과학적 방법은 반증주의로 각각 회귀하였다. Middle school science teachers performed activities to identify their philosophical perspectives of science through a series of "card game" planned for this research. The subjects of the research were 156 middle school science teachers participated in the 1997 in-service science teachers' training course of the Gyeong Sang Nam Do province. The teachers performed the activities for this research for three hours during their workshops. We found that the subjects in the research were turned out predominant in the inductivistic views regardless of their major, gender, and career. In addition, in the process of collective consensus making, views of (a) the criteria of demarcation and (b) the patterns of scientific change were shifted to the extreme inductivism, (c) the epistemological status of scientific knowledge to the relativism, and (d) the scientific methods to the falsificationism, respectively.

The purpose of format conversion is to convert a wide range of personal computer video formats to a target format. Circuits for the conversion have been developed by means of interpolation techniques, such as zero-order interpolation, bilinear interpolation, and bisigmoidal Interpolation. This paper purposes an adaptive scan converter using bisigmoidal interpolation The value of the control constant of the bisigmoidal interpolation polynomial is adaptively selected according to the difference of neighboring pixel values for a new pixel on the target format. The converter has been modeled in VHDL, on Max+PlusⅡ and implemented with a FPGA chip. The circuit gives much better conversion performance than a scan converter with a fixed control constant based on the bisigmoidal interpolation.

교수-학습과정의 기호학적 탐구

이찬주,박범석 동국대학교 교육연구원 2005 교육문제연구 Vol.16 No.-

기호학적 입장에서의 의미 전달은 기호에 의한 의미의 교환이라 할 수 있다. 기호가 언어보다 폭넓은 인간 의식의 이해를 반영한다는 점에서, 인위적으로 설정된 상징체계 이외에 자연스러운 상황이나 이미지 자체도 하나의 기호적 의미의 범주로 해석될 수 있다. 교사와 학생의 가르치고 배우는 활동 역시 지식의 일방적인 전수가 아니라, 다양한 기호들이 상호소통함으로써 의미전달과 창출을 끊임없이 경험하는 해석적 활동이 된다. 교육활동 그 자체가 일종의 해석적 활동이기 때문에 이들 사이에 어떤 형태의 의미교환이 이루어지는가를 규명하기 위해서는 교수-학습의 기호적 역동관계를 이해하는 일이 선행되어야 한다. 따라서 교사와 학생 사이의 의미전달과 획득의 측면을 인간의 기호적 인식의 특성을 통해 밝히는 것은, 기존의 텍스트의 성격 이해를 중심으로한 해석적 연구에서 한 걸음 더 나아가 의미화 과정에서 일어나는 교육 주체들의 인식과정을 설명하는 하나의 계기가 될 것이다. The purpose of this study is to investigate the meaning of teaching-learning process in the view of Semiology. In Semiology, education is the enlarging process of meaning between teacher and students in the classroom as a field of signs. It is the hermeneutics activities to student which learn from the teacher and the text. It means students don't take the meanings not just direct way but translating way as their own meaning structures. In the same way, we can say that even teachers don't convey the meaning to students. They translate the meanings for students representing their own understanding structures. It can be said that the teaching and learning process is the relationships of hermeneutic cycle. In Semiotic view points, educational texts is not just the tools of information transmission. We can recognize the educational texts is the dynamic products from the meaningful actions between the two educational agents. These kinds of Semiotic views can give the new visions to clarify the educational communication between teachers and students in the classroom.

과학교사들의 과학철학적 관점이 중학생들의 과학의 본성 개념에 미치는 영향

소원주,김범기,우종옥 한국교원대학교 과학교육연구소 1998 청람과학교육연구논총 Vol.8 No.1

과학적 소양에는 과학의 본성에 대한 적절한 이해를 함의한다. 그러나 학생들의 과학의 본성 개념에 영향을 줄 수 있는 요인에 대해서 알려진 것이 별로 없다. 본 연구의 목적은 과학교사들의 과학철학적 관점이 그들이 가르치는 학생들의 과학의 본성 개념에 직접적으로 영향을 미칠 것이라는 가정에 대한 타당성을 검토하는 것이다. 본 연구에서 과학교사와 학생의 과학관을 비교하였을 때, 과학교사들의 과학의 관점이 학생들의 과학의 본성 개념에 영향을 줄 것이라는 연구 가설은 기각되었다. 즉, 본 연구의 자료에 의하면, 교사들의 과학의 관점과 학생들의 과학의 본성 개념 사이에 아무런 유관 관계가 없었다. 이는 과학의 본성이 학생들이 요구나 교육과정 목표로써 고려되거나 교육되지 않는데 따른 귀결이다. 이 연구 결과는 중등 과학교육에서 더 한층 과학의 본성 개념 함양의 필요성을 제기하는 것이다. Scientific literacy implies an adequate understanding of the nature of science. However, little is known about factors that can influence students' conceptions of the nature of science. The purpose of this study was to test the validity of the prevalent assumption that teachers' philosophical perspectives of science directly influence their students' conceptions of the nature of science. A comparison between science teachers' and students' perspectives of science did not support the assumption that a science teachers' perspectives of science is significantly related to students' conceptions of science. The data clearly indicated that there was no relationship between teachers' philosophical perspectives and those of their students. The results convincingly indicated that the nature of science was not being considered or taught to students as a consequence of students' needs and curriculum guide objectives. It is believed that the results of this investigation will help to redirect the focus of future efforts to promote more adequate conceptions of the nature of science in our secondary schools.

Udo and Schemeori oreum[cow's head rising]: "Cow's head rising" and "Cow's head mountain" have both a shape just like a cow is lying and considering that two places' geographically high location and its district name are also configurative, we can sense landscape Image as a "a cow-shaped island lying down" and Jeju I slanders' unique consciousness of the geographical features. Udo Palkyong[eighl picturesque sights at Udo]ail shows a format of "poem-recitation-after titling" consisting of a lour-Chinese-letter word derived from the ancient history as a format for semantic access, but if we take a little closer look at it, it is noted that Udo Palkyong turns to be ontological subject of landscape mainly targeting formative elements. Therefore, in formative sense, Udo Palkyong belongs to China's famous sight experience type, but as for the contents, it is much closer to famous landscape type haying the formative elements like Gwandong Palkyong or Danyang Palkyong as major landscape elements. It was found that the seven landscapes centering on Hanlasan Baerokdam[a crater lake on top of Halasan], except Cheonjingwansan brook haying three landscapes, iorm their landscape within a 0.87-kilometer radius. In addition, as for viewing composition pattern, there are live panoramic landscapes which reflect the features of Seaside Landscape; two geographical landscapes. and one focal landscape. Besides, the prospect type consists of mostly landscape type and far-and-wide viewing type. As for landscape format, there appear a variety of features of main landscape subject's visibility areas from a distant view to a short-range view, and also structural properties within the physical, landscape, visual, psychological influence. In addition, there appear a variety of viewing compositions, such as the five panoramic landscapes, two detailed landscapes, and one geographical landscape. We can trace a vestige of a tense atmosphere of bodhisattva's death and the pursuit of stability of dialectical composition. Conclusively, Udopalkyong is well expressive of aesthetic characteristics, at a viewpoint of time and space, boasting of exceptional landscape quality regardless of day and night, heaven and earth, front and rear, and at whatever direction Udopalkyong may be viewed.

Study on the synthesis of chemical nucleases that have ability of cleavage of RNA or DNA to investigate the structure of nucleic acids was performed. We synthesized Ni-complex that was synthesized by Karn and Busch (1966) and identified the specificity and ability as chemical nuclease by Chen. et. al. (1993), and Cu-complex and Cd-complex that were presumed as having specificity similar to Ni-complex in terms of the structure and specificity and ability as chemical nuclease. The spectra of synthesized new transition metal complexes were compared with those of Ni-complex. Results of comparing data of UV and IR spectra of Cu-complex and Cd-complex with those of Ni-complex showed that the structures of newly synthesized transition metal complexes were similar to the structure of Ni-complex. The yield of synthesis of Ni-complex, Cu-complex, and Cd-complex was 81%, 7%, and 39% respectively.
