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.

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.

This thesis is a study on Sook-Jae Lim(1899~1937) and Korean modern design. In modern Korea, design like most cultural advances came from western culture, that was introduced via Japan. So Korean design can be betterunderstood from observing Japanese modern design history. The research on Japanese modern design, however, is not being done actively. Sook-Jae Lim was the first Korean to graduate from the Department of Design at Tokyo Fine Arts School (currently the Tokyo National University of Fine Arts and Music). He died at a premature 38 years old, so very little of his works exist. That makes the study about him very difficult. From this perspective, the study aims to examine modern design concepts and styles accepted into Korea from Japan and position Lim as an early design pioneer in Korean design history, by using research of Korean and Japanese design fields in the modern era with focus on Lim and his works. Chapter II researches the process of how the concept of design was formed in modern Japan and how the "Art-Nouveau" style not only represents early modern design but also features Lim's works dominantly. Chapter III looks into the process of how the concept of design was formed and which design styles were introduced and applied in modern Korea. Chapter IV analyzes how Lim's viewpoint on design and his works were developed with observations about the tendency of the Japanese design field and curriculums of the Tokyo Fine Arts School during the period of his college days.

The modern agriculture has been damaged through the rapid changes due to the policy of the plundering of food during the Japanese colonial era, the Korean War, the industrialization, etc. The purpose of this research is to define the scope and the concepts of the modern agricultural heritages and to establish utilization standards of the modern agricultural heritages. With such a purpose, this research proceeds with three phases. First, the definitions the systems of the organizations the modern age and the modern agricultural heritages. Second, the analyses of the patterns and the special characteristics through the general investigation. Third, the regeneration through the comparative examinations of the case examples of the conflicts between the modern agricultural heritages. And the new attempts through the drawing of the new discussion points and the advanced tendencies are proposed. It is judged that this research will provide the point of the aim when looking at the modern agricultural heritages as the historical and cultural assets, and that it will provide the several principles when formulating the plans for the invigoration of the farm villages and the plans for the developments of the agricultural regions and provide the bases for the practical formulations.

In spite of important researches and translational works of the Joseon mathematical treatises in the 80's and on, these results were almost out of reach to the school teachers as well as students due to the antiquity of their contents and the terms used. In order to make our traditional mathematics approachable to the middle and high school students, it will be educationally meaningful to reinterpret them tuned at the student's level using modern terminology and symbols. In this study, we reinterpreted 9 problems from Cheukryang Dohae, which is one of the representative mathematical books of Joseon Dynasty. We used the terminology and symbols from the school curriculum. We also reconstructed two of them using modern metrologies adapted to modern situations adding illustrations and photos, so that they are useful at the teaching site.

Occupational risks are often underestimated in midwifery. It is not commonly known that occupational risks were originally described by the Italian physician Bernardino Ramazzini (1633-1714) at the beginning of the 18th century. Our aim was to describe occupational risks in midwifery from Ramazzini to modern times. The original text by Bernardino Ramazzini was analyzed. A review of modern scientific articles on occupational risks in midwifery was conducted. Ramazzini identified two major occupational risks in midwifery: infections and awkward postures. Modern literature seems to agree with his considerations, focusing on infection, use of universal protection and personal protective equipment, and musculoskeletal problems. Modern studies also evidenced posttraumatic stress disorder that was probably postulated by Ramazzini himself. The poor number of articles in literature on midwives' occupational risks shows a lack of interest toward this issue. Prevention should therefore be emphasized in this field, so high-quality studies on occupational risks in midwifery are needed.

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.

The purpose of this study is to investigate the general characteristics of modem library which was in a germinal stage at the opening period of Korea. The major findings of this study is summarized as follows. 1. Modern libraries which began to develop during the opening period of Korea were deeply rooted in the spirit of patriotism. After 1905, which was the year of so-called Korean-Japanese Protocal concluded under the Japanese military pressure, the patriotic enlightenment campaign against foreign penetration developed rapidly throughout the country. Accordingly, the movement for establishing modern library was carried out among advanced reformers. 2. The first modern school library was built in the private school of Wonan established by the residents of Wonsan area. They believed that the best way to strengthen the national power to oppose Japanese penetration was to learn the Western culture and technology. 3. The first modern public library named The Central Library of Korea was originated by Oh Ha Young and his comrade in 1906. Included among these promoters of the library were Yun Chi Ho and Min Sang Ho, two persons who had experienced Western culture during their study abroad. 4. Pakmunkuk, the newspaper office of the government, had its own library in 1883 which was the first modernized special library in Korea. 5. Major factors which hindered the rapid growth modern libraries m the opening period are as follows; (1) Lack of people's demand fer the library. (2) Limited scope of the publications(mainly school text-books) (3) Poor financial conditions. 6. Japanese invasion in 1910 had broken the growing roots of modern libraries in formative stage.

Architectural essence of John Ruskin's discourse can resolve itself into natural beauty, craftmanship, and truth in structure, surface, and process. His theories became disciplines of modern English school, Art and Craft and Free architecture, in aspects of organic architecture, morality, and rationality. These concepts disseminated continental Art Nouveau and also became it's basic principles. But his empirical theories hated use of machine, and should find a ideal model in medieval romanticism of Gothic. Anti-machine, as a instictive guideline of English modern architecture, couldn't cope with the industrialization of 20th century, and Gothic revival interfered with creating a new style. Muthesius' discourses were taught by the power of group movements and modern concept of form in English school, originally by Ruskin. But he accepted the potentiality of machine and mass production, and stressed creating the new German style suitable with machine. With the progress of Deutscher Werkbund, his theories were advanced to 'quality' connected with craftmanship, to discourse on mechanical 'form', and lastly to 'standardization and type' for mass production. Mechanical functionalism of Muthesius and DWB were sophiscated and handed down to Bauhaus, and then finally helped establishment of the Modern Architecture and Internationalism. Both English and German modern architecture owed their contribution as well as limitation to Ruskin and Muthesius as theorists. Through this comparative study, we can see the priority of theory to practice, the theoretical justification based on insight for its society and future, and the practical character of theory itself.

The purpose of this study is to scientifically analyze physicochemical characteristics of the roof tiles used for palaces in the Joseon Dynasty which stored in Changdeokgung material storage and Seooreung Jaesil and the modern handmade ones which made by N company to understand the differences between their manufacturing techniques. Through chromaticity, cross-sectional observation, component analysis, and crystal structure analysis, it was possible to confirm the physicochemical properties and fired properties of the roof tile. Roof tiles from the Joseon Dynasty have a wider colorimetric range and higher apparent porosity and water absorption, on average, than the modern roof tiles. The cross section of the Joseon Dynasty roof tiles shows that most clay minerals have not been vitrified, remaining in the form of atypical particles, while the modern roof tiles have denser clay materials. X-ray diffraction analysis identified low-temperature minerals such as micas in Joseon roof tiles but no peak of these minerals was observed in the modern roof tiles, implying that the modern ones are fired at higher temperature than the Joseon ones. Therefore, the modern roof tiles are fired at higher temperature and have higher density than the Joseon ones due to the use of pugmills. The general content of main ingredients was similar between the two. Additionally, the principal component analysis of trace elements in the Joseon roof tiles showed that most samples were from similar areas. It seems that the Joseon roof tiles were manufactured using soils supplied from a specific region at the same timeframe and their consistency in the content of principal components implies that they also have similar mix proportions of clay.
