  • The purpose of this study is to investigate the possibility of introducing the history of science in modern Korea into elementary education. Although there are many studies on applying a history of science to science education, they do not pay attention to the history of science in modern Korea. I survey research papers on the history of science in modern Korea and science education based on a history of science, and elementary science textbooks in Korea, Japan and the US. When we apply the history of science in modern Korea into elementary education, elementary students will recognize science has close relations to Korean culture and history and they will develop the familiarity with science. I show there are 3 ways using the history of science in modern Korea in elementary education: 1) Applying Korean scientists' research contents to science education, 2) Measures to evaluate Korean scientists correctly, 3) Materials for science education programs for gifted elementary students.

  • This study explored the philosophical Modernity with the Enlightenment in relation to cultural and aesthetic modernism rooted in Modern furniture, which directly reflected modern culture and society with rationality, science, individualism, progressive, universal truths, etc, using qualitative analysis about the related literature as the principal methodology. A fundamental philosophy of the modern furniture influenced by Industrial Revolution is that the dictates of function and industrial technology must be decided by form. The theory and practice of the International Style in modern furniture came from the modern aesthetics in the philosophy of Modernity. As a result, as influenced through the Enlightenment project and the relationship of individual to society in relation to cultural and aesthetic modernism, and the three modern movements with furniture, which are Arts and Crafts movement, Art Nouveau, and Art Deco, represented the beginning style of modern furniture design toward functionalism or minimalism.

  • This study deals with arbitration award via modern technical means; because e-Arbitration is deemed to be one of the most important substitute means for the settlement of disputes arising from electronic transactions. This type of arbitration is characterized by fast settlement of disputes, as well as fast enforcement of awards rendered thereon. The researcher seeks to indicate the content of the award, the conditions for rendering it, and to analyze the legal provisions related to its legal basis in the Saudi Law of Arbitration. This study shows that an arbitration award, rendered via modern technical means has a number of advantages, such as fast settlement, less cost, and keeping pace with modern technology, which is an aim of Saudi Arabia Vision 2030. The study also points out certain problems facing arbitration via technical means; however, the most important of which is the insufficiency of some legal rules associated with traditional arbitration, as contained in the Saudi Law of Arbitrator, which are incompatible with or applicable to an arbitration award which is rendered via modern means.

  • The purpose of this study was to find out how to be pursued elementary teachers' science instruction according to their understanding toward science. Sixty elementary teachers were involved in the questionnaire, investigating understanding on the nature of science and the science teaching. Two elementary teachers' science classes are observed. Their instructional objectives were analyzed. And their understanding toward science was measured. Teacher A had consistent modern philosophical views of science on the nature of science and science teaching, and teacher B had not consistency Klopfer's science educational objectives category was used to analyse instructional objective. The ideal proportions of the instructional objectives of the observed classes were established from science education specialist group. You ideality index was calculated. You ideality index indicate how far from the ideal proportions of the instructional objectives the observed instruction is. Relative proportions of instructional objectives appeared in science classes were compared with ideal instructional objectives. Instructional objectives containing the modem views appearing classes observed were compared according to teachers' understanding toward science. As results, teachers' understanding toward science showed lack of consistency, which is consisted of modern philosophical view of science on science teaching: modem and classical philosophical view of science on nature of science. Teacher A's instruction was approached more closely to the ideal proportions of the instructional objectives, showing fewer You ideality index. Instructional objectives containing the modern views are more appeared and closer to ideal proportions in teacher A's classes than in teacher B's. A teacher having modern understanding on nature of science would instruct science with modern scientific philosophical perspectives. Therefore teacher preparation programs should include more contents about modern philosophical understanding on the nature of science.

  • 본 연구에서는 초등학교 과학 교육과정에 현대 물리 내용을 도입하는 것의 가능성을 논의하였다. 초등학생에게 현대 물리를 지도하는 것이 왜 필요한지 현대 물리 도입의 필요성을 논의하였고, 실제로 초등학생에게 현대 물리를 지도한 외국의 사례와 연구 결과를 살펴보았다. 그리고 구체적으로 우리나라 초등학교 과학 교육과정에 현대 물리를 도입하기 위한 몇 가지 방안을 제안하였다. 현대 물리는 학생이 경험하는 다양한 일상적 상황과 연계될 수 있으며, 학생들이 배우고 싶은 내용으로서 과학에 대한 흥미와 호기심을 높일 수 있다. 또한, 아직 고전적 자연관이 굳어지지 않은 초등학생에게 현대 물리를 도입하면 새로운 자연관 형성을 도울 수 있다. 최근 현대 물리를 초등 수준에 도입하기 위한 해외의 몇몇 프로젝트에서도 학생의 이해와 흥미 증가에 관한 긍정적인 결과를 보고하고 있다. 연구자들은 초등학생 수준에서 이해가 가능할 것으로 생각하는 몇 가지 주제에 대해 구체적인 내용수준과 지도방안을 간략하게 제안하였다. 이러한 제안은 후속 연구를 통해 적절한 자료개발과 경험적이고 실증적인 연구를 통해 그 가능성과 효과가 입증되어야 하지만 현대 물리 도입 가능성에 대한 논의를 진전시킬 것으로 기대한다.

  • We research a system of compressed-sensing computational ghost imaging (CSCGI) based on the intensity fluctuation brought by turbulence. In this system, we used the gamma-gamma intensity-fluctuation model, which is commonly used in transmission systems, to simulate the CSCGI system. By setting proper values of the parameters such as transmission distance, refractive-index structure parameter, and sampling rates, the peak signal-to-noise ratio (PSNR) performance and bit-error rate (BER) performance are obtained to evaluate the imaging quality, which provides a theoretical model to further research the ghost-imaging algorithm.

  • In order to investigate the ultraviolet-excited photoluminescence properties of phosphor coatings and their relationship to thickness, Lumogen coatings with different thicknesses were deposited on quartz substrates and charge-coupled device chips by thermal evaporation. The variation of the film thickness affected the crystallite size, surface roughness and fluorescence signal. It was found that the Lumogen coating with the thickness of 420 nm has the largest luminescent signal and conversion efficiency, and the corresponding coated charge-coupled devices had the maximum quantum efficiency in the ultraviolet. These results provided one key parameter for improving the sensitivity of Lumogen coated charge-coupled devices to ultraviolet light.

  • The threads of this thesis are several theoretical issues of modern urban ideals. Modern architects and urban designers conceived their individual artifacts, which assumed to be laid out on the new settings totally different from the existing urban fabrics derived from inherently medieval ones. In the discussion of modern ideal society, the Industrial Revolution and the Enlightenment was a pivotal point. Innovations in technology and expanded living territories since the double revolution have been critical factors in the evolution of new ideas of urbanism. The tremendous success in science and technology led a way to the 'science-fiction' environment as a destined apocalyptic world. The dream, whether it was socialist or in any other believes, to a pastoral utopia beyond the capitalist society was represented through the ideal cities, which were modern versions of arcadia in the other approaches. Two sides of revolutionary ideas are presented as a futurist city and a garden city, which are on the separate notions but co-existed or overlapped in a single urban project such as in Le Corbusier urban schemes or even Tchumi's recent work, Parc de la Villette. Urban ideas in the twentieth century are based on urban naturalism, the notion of which was consistant from abbe Laugier to Le Corbusier, as well as machine aesthetics interpreted in terms of archeological research and modern technology.

  • Science fiction films touch coming-future themes, particularly those referring specifically to futuristic technology and its influence over human life. Dealing with the resistance of the replicants in the approaching millennium, Blade Runner brings the feat of modern civilization into doubt through the image of the dystopian future. In Blade Runner, a city is filled with waste, pollution, and dirt and a corrosive rain falls from the polluted clouds. Adorno criticizes contemporary society and its civilization. Characterizing advanced capitalist society by its total administration penetrating into every sphere of life, he contends that modern society promotes alienation, atomization, conformism, and fatalism. Blade Runner provides a chance to contemplate the problems of modern society, proposed by Adorno's critical works. Therefore, this paper attempts to analyze futuristic characteristics described in the film with Adorno's critique of modern society.

  • A position-sensitive CsI(Tl) crystal array coupled with the multi-anode position sensitive photomultiplier tube (PS-PMT), Hamamatsu H8500C, has been developed at the Institute of Modern Physics. An effective, fast, and economical readout circuit based on discretized positioning circuit (DPC) bridge was designed for the 64-channel multi-anode flat panel PSPMT. The horizontal and vertical position resolutions are 0.58 mm and 0.63 mm respectively for the 1.0 × 1.0 × 5.0 ㎣ CsI(Tl) array, and the horizontal and vertical position resolutions are 0.86 mm and 0.80 mm respectively for the 2.0 × 2.0 × 10.0 ㎣ CsI(Tl) array. These results show that the CsI(Tl) crystal array with low cost could be applied in the fields of medical imaging and high-resolution gamma camera.
