  • This study intends to delineate the characteristics of various perspectives on the nature of science (NOS) through the textbook analysis. Thus, centering on a science textbook called Science Laboratory Experiments, this study analyzes the elements of the NOS from three different perspectives: the consensus view, features of science (FOS), and family resemblance approach (FRA). While the consensus view highlights the similar elements of the NOS across the topics, the FOS is concerned about empirical ways for doing science. The FRA rather focuses on socio-cultural aspects of science activities. While the consensus view is useful to reify the features of the NOS, the FRA helps to understand science from various viewpoints. Regarding the philosophical account for three perspectives, all of them are ambiguous to some extent. The consensus view holds contradictory dispositions e.g., relativism vs. (post-)positivism, and critical realism and instrumentalism. The FOS supports empirical tradition but cannot effectively cope with the anomalous situation. The FRA is useful to show up the ways of science in both microscopic (personal) and macroscopic (social) viewpoints. However, the broader concept about science may mislead understanding of the NOS. Consequently, this study provides some implication for improving the framework of the NOS and teaching the NOS in the classroom.

  • While single view video coding uses the temporal prediction scheme, multi-view video coding (MVC) applies both temporal and inter-view prediction schemes. Thus, the key problem of MVC is how to reduce the inter-view redundancy efficiently, because various existing video coding schemes have already provided solutions to reduce the temporal correlation. In this paper, we propose a global disparity compensation scheme which increases the inter-view correlation and a new inter-view prediction structure based on the global disparity compensation. By experiment, we demonstrate that the proposed global disparity compensation scheme is less sensitive to change of the search range. In addition, the new Inter-view prediction structure achieved about $0.1{\sim}0.3dB$ quality improvement compared to the reference software.

  • The purpose of this study was to examine philosophical views on science of two influential curriculum documents, AAAS' s Benchmarks for Scientific Literacy (Benchmark) and NRC's National Science Education Standards (Standard), and to get educational implications about a desired philosophical view on science at a school science level. In order to determine the philosophical views on science explicitly suggested in the documents, Soh's Philosophical Perspectives Probe (PPP) was used as a framework for analysis. Forty preservice teachers reviewed the documents, extracting paragraphs with which statements of the PPP' s questions would agree. The results of the study were as follows: First, the Benchmark's philosophical view on science corresponds to the borderline between inductivism and eclecticism, or eclecticism close to falsificationism. The philosophical positions by the PPP' s themes are very different. Second, the Standard's philosophical position on science corresponds to inductivism close to eclecticism. Its philosophical position by the themes of the PPP is very different like the Benchmark. These results indicate that philosophical positions of the documents are more complex than popular conceptions would have it. That is to say, the results suggest that the science curriculum documents hold not only a contemporary philosophical view on science but also a traditional view on science, and that the philosophical positions on science are different from each other by documents and even by the PPP's themes in the same document. The results suggest that the philosophical views on science in school science contexts need to be adjusted and presented to K-12 students according to topics related to philosophy of science.

  • The development of life science has given many insights into life phenomenons to mankind. Nevertheless, many questions for various phenomenon in life has not been satisfied. Recently, scientific development in human's knowledge showed the limitation of science comparing With the variety of life phenomenon. The fundmental reason of the limitation is thought that the subject of study in life science has been material, and so life has been thought a matter of material in life science. The thought of Hu Jun about this problem, the nature of living things is an important interest in Korean Traditional Medicine, Haneuihak(韓醫學). In this study, the view of human body and disease of Hu Jun(許浚) about the nature of living things which was appeared in 『Donguibogam』 was illuminated. The content of 『Donguibogam』 was edited in the order of Naekyung(內景篇; internal part of the body)ㆍOuihyung(外形編; external part of the body)ㆍJabbyung(雜病篇; diseases)ㆍTangaek(湯液偏; medicinal decoction)ㆍChimgu(針灸篇; acupuncture and moxibustion). The part of Naekyung(內景篇; internal part of the body) is thesis about basic theories and his thought about human body and life, which was seen in ‘Shinhyungjangbu-do(身形臟腑圖; figure of body and shape, and the organs and viscera)’ㆍthe part of ‘Jeong(精)’ㆍ‘Gi(氣)’ㆍ‘Sin(神)’ theory. In this study, the parts which were related with his view of life were selected and compared with the China philosohy of those days to elucidate what is his thought of life appeared in 『Donguibogam』.

  • Currently, there are little evaluated model for each industry and systematic analysis for each item about current business web sites. And the approach way to improve it all depends on individual. This research is about two different points of view on I-Evaluation development as an approach method to provide analysis, evaluation, and guideline on business web sites. The one is about developing a working step and a site evaluation model that are necessary to improve the quality of site. The other is about a framework development to apply a feedback on site most rapidly and site optimization. The former is from the methodological point of view for I-Evaluation, and the latter is from the point of view for I-Evaluation Framework. In terms of methodology, developing site evaluation model and defining a working step belong to it. Site evaluation model means customizing each customers web site, using each evaluated scoring model which can be a standard for each industry to analyze a similar business web site. Defining a working step means defining input and output parameters for composed elements, working processes, and results analysis on an evaluated model. And also it includes building a working environments to automatic steps mentioned the above by clarifying them.

  • The purpose of this study is to assess gifted students' conceptions about nature of science (NOS). Scientifically gifted students who are expected to be professionals in the future should possess an adequate understanding of NOS that if firm foundation for scientific career. 47 volunteers from the 8th grade gifted science program in Seoul National University Gifted Education Center participated to answer questions inquiring NOS conceptions. Their answers were analyzed and compared to different groups such as non-gifted students and younger gifted students. As a result, gifted students' understanding of NOS appeared to surpass that of non-gifted students in many aspects and it seemed that gifted students formed their NOS view in early ages. The relative weakness in their NOS conceptions was found in understanding of scientific enterprise. Their strong misunderstanding about obstacles that minority people would face in scientific enterprise was noticed, too. They admitted that there has been discrimination in scientific enterprise, but they wrongly believed that outstanding scientists cannot be affected by it. Further studies will be required to probe more.

  • 이 연구는 중등학생들이 가지고 있는 자연에 대한 관점중 인식론적 관점과 존재론적 관점과 그러한 관점의 원인을 알아보고자 하였다. 156명의 중등학생들이 참여했고, 자료는 설문지를 통해 수집되었다. 이 설문지는 선행연구에 기초하여 연구자들에 의해 개발되었다. 연구 결과, 중등학생들의 자연에 대한 관점 중에는 자연은 알 수 없다는 인식론적 관점이 가장 많았다. 이러한 관점의 근원은 자연의 규칙성과 조화, 예측 가능한 자연 현상, 자연 현상의 순환 과정이나 인과 관계, 자연과 인간과의 관계 등으로 매우 다양하였다. 중등학생들의 존재론적 관점에는 초자연적인 관점이 가장 많았다. 존재론적 관점들 중에서 학생들의 초자연적 관점은 그들의 신학적 측면의 영향이 광범위하게 나타났다. 과학이 다루는 세상이면서 동시에 과학의 대상물이 존재하는 물질세계인 자연에 대한 인식론적 관점과 존재론적 관점은 학습자가 과학 학습을 어떻게 이해하는지에 대한 바탕을 제공하는 중요한 자료가 된다. 앞으로 학생들이 가지고 있는 자연에 대한 인식론적 관점과 존재론적 관점과 그들의 과학 학습 과정 사이의 관련성의 연구가 필요하다.

  • As science programs emphasize an understanding of the nature of science, it is needed to assess students' views on a wide range of science-technology-society topics. The purpose of this study is to investigate the views of high school students about some selected topics of the epistemology of science. The selected topics include the meaning of science, scientific assumptions, values in science, conceptual inventions in science, scientific method, consensus making in science, and characteristics of the knowledge produced in science. Identified preconceptions in the study are as follows: Science was seen as improving the world(20%), and technology was defined as the application of science(35%). Almost half of the sample(49%) subscribed to a view consistent with a creationist posture and large group of students(46%) expressed a purely ontological view. Only minority of the students(5%) discounted the role played by private science values, but one half of the sample denied the fact that gender-related values can influence the knowledge that scientist construct(53%). Only a small potion of the sample(5%) held a view contrasting to contemporary epistemology of science, but the majority(67%) expressed a simplistic hierarchical relationship in which hypotheses become theories and theories become laws. One third of the students(33%) held a preconception that the scientific method composed of questioning, hypothesizing, collecting data, and concluding. Students did not appreciate the role of consensus making in science(33%). An out-dated epistemic perspective describes the progress of science as simply an accumulation of knowledge(4%). In general, it was concluded that most high school students did not hold efficient understanding on the nature of science. It can be said that no adequate and consistent instruction took place to provide students with an authentic view of the nature of science.

  • 과학교육의 목표인 과학탐구에 대해서 초임과학교사들은 어떻게 인식하고 있는지를 조사하였다. 교사의 과학탐구에 대한 인식은 학생들의 과학탐구에 대한 인식에 영향을 미치는 것을 고려할 때 연구의 의미가 있다고 할 수 있겠다. 126명의 초임교사들을 대상으로 일반적인 과학탐구에 대한 인식과, 과학의 본성, 그리고 과학-기술-사회의 관계에 대한 인식을 파악할 수 있는 설문지를 개발하였다. 초임과학교사에 의한 과학의 본성과 과학-기술-사회 관계에 대한 인식을 포함하여 전반적인 과학탐구에 대한 인식은 코딩작업을 통해 파악되었으며 이 과정을 통한 자료수집 및 분석의 타당성 및 신뢰성은 과학교육전문가와의 토론을 통해 구축되었다. 이 연구의 결과는 다음과 같다. 초임교사들은 과학탐구를 실험적인 절차적 기술과 과학적 사고를 함양하는 기회로 정의하고는 있지만 과학탐구를 하는 이유와 과학탐구를 실행하는 데 있어 교사의 역할은 실험적인 절차적 기술을 함양하는 기회로 파악하고 있었다. 과학탐구에 대한 정의나 목적 또는 교사의 역할에 대해서는 정의적 영역에 해당하는 요소는 거의 파악되지 않았다. 과학의 본성에 대해서는 과학적 관점보다는 순수한 관점으로 인식하고 있었으며 과학-기술-사회의 관계에 대한 인식은 긍정적인 태도를 보여 주었었다. 초임교사를 위한 조직적인 교사교육을 개발할 필요가 있다.
