The purpose of this study was to suggest that the history of science be introduced to students in the secondary school to help understand the developmental process of the scientific concepts, especially the concept 'heat'. Reviewing the national and international researches related to students' concept 'heat' revealed that many students tend to grasp the wrong concept of heat based on the caloric theory. Studies on definitions and explanations of the concept 'heat' and related concepts in secondary school science textbooks indicated that the way 'heat' was described could not help students to correct their misconceptions. In conclusion we need to include the historical and developmental process of scientific concepts such as heat in textbooks.

This is a literature study about the concept of 'Division into Equal Parts' in middle school geometry. First, we notice that the concept of the division into equal parts in middle school geometry is given in four themes, which are those of line segments, angles, arches and areas. Second, we investigate and analyse the historical backgrounds of these four kinds of divisions into equal parts. Third, the possibility of extension in terms of method and concept was researched. Through the result of this study, we suggest that it is desirable to use effective utility of history in mathematical teaching and learning in middle school.

The purposes of this study which was conducted by inquiring into some curricula for Emergency Medical Dispatchers(EMDs) are to introduce a curriculum into Korea and develop a textbook for training of the EMDs in Korea. The conclusions from this study were summarized as follows; (1) There are some professional demands in our Emergency Medical Dispatch field therefore, now it is necessary to set up an education system for the EMDs in Korea and give them a suitable name to this change. (2) Some historical turning points which are condensed from the developmental process in the USA. including "Medical Self Help" with no formal dispatch protocols, Medical Priority Dispatch System, Practice Standard, Dispatch Protocols will serve as a good reference for establishing and education system for the EMDs. (3) To effectively train the EMDs in Korea, we needed to be introduced to Emergency Medical Dispatch : National Standard of Curriculum from the U.S. Department of Transportation & the National Highway Traffic Safety Administration which is made up Basic Emergency Medical Concepts, Information Gatherin & Dispatch, Introduction to the Emergency Medical Dispatch Protocol Reference System(EMDPRS) & 32 Chief Complaint Types. (4) The introduced curriculum closely related to the medical director, the direct indirect medical control, the scope of practice in the USA, should be revised for the Emergency Medical Service System of Korea. But to reduce the developmental process & time, it is necessary to postpone the consideration on these factors until publishing a new textbook. (5) This study which gives the cornerstone about some developmental methods on textbook for EMDs will be helpful to build up an education system for EMDs such as Curriculum, EMD Certification, National Academy of Emergency Medical Dispatch to fit the Emergency Medical Service System of Korea in the future.

The Korean clothing industry according to historical documents has a long and deep history. We can deduce the fact that cloth in material was self reliant during the pre-historic period. Although we can not find evidence of clothing material trade from the Three Kingdom era we find active trade with Kang, Jin of China and Japan followed by the spread of Korean clothing material manufacturing skills to Japan. Meanwhile the actual progress of the clothing industry came with the manufacture of cotton stuff in the Koryo era and the official and unofficial trade which brought import and export activity to Korea. Also the manufacture of clothing material by women labor although backward as it may be can be seen as stroug evidence that women labor continuously kept up the development of Korean industry. After the Koryo dynasty trade in clothing material and other clothing items contined with other nations. In conclusion we must not think that the Korean clothing industry started active development from the Chosun dynasty. It is important that we realize this fact and looking at the continuous progress of the Korean clothing industry through historical documents from early history to the Chosun era we rightly evaluate history and be proud of this legacy and also reevaluate the wrong views held before.

The purpose of this thesis is to trace the development of cotton Early Chosun Period by examining the historical literary sources : such as production of cotton various uses of cotton trade with other countries The developement process of cotton fabrics during this period can be divided into three stages. The first stage which can be discribed as a settling period lasted 27 years from A.D. 1392 to 1418. In this stage cotton fabrics were just about to be used as fabrics for popular clothing. The second stage which can be discribed as a developmental period lasted 50 years from A. D.1418 to 1468. In this stage cotton fabrics were mainly produced in the southern parts of the country which are Kyungasng-Do, Choongcheng-Do and Jeunla-Do. And cotton fabrics were used not only by the common people but also by the royal family. The third stage, that is the last one was an extensive period and lasted from A.D.1469 to 1592. In this stage as the demand for cotton fabrics greatly increased the production from southern parts of the country fell in short of the supply needed. Therefore the production was extended to the northwestern parts. In addition cotton fabrics finally came to be used as money to value the goods.

Investigation for industrial revolution has been recognized as an important issue of historical science, since industrial revolution itself was a historical moment in modern economic society and in the forming of modern capitalistic culture. If clothing culture had been developed in close relation to social culture. industrial revolution which gave a base for modern capitalistic culture, would be a birth of modern clothing as well as a moment for modernization of western clothing. As it takes for granted that industrial revolution, historical phenomenon is a developmental base of modern clothing culture. This study tried to enlighten the origin of modern clothing culture phenomenon with investigation of industrial revolution as a historical moment in modern clothing culture through documental study. Historian's point of view and method of studying are important when we investigate the clothing phenomenon. Although culture phenomenon of industrial revolution has been evaluated usually through socialogical aspect, studying for clothing culture phenomenon must be carried out on aethetical as well as well as sociological aspect, on account of dualism of clothing, as it is social and artistic nature. In 19th century, there were technical improvement, changing patterns of production, changing social relation and beginning of mass culture. At the same time clothing culture phenomenon was changed in relation to modern capitalistic society. The findings of the study could be summarized as follows. 1. Technical improvement in textile industry and fitting process brought about mechanization of clothing industry. 2. Appearance of popular clothing culture made it easy to spread to various classes of society. 3. Development of transportation system and communication channel made it internationalization of western clothing. 4. Recognition of importance in functional style of clothing. 5. The pursuit of modern aesthetics made rapid changing mode of clothing. Above distinctive features of modern clothing culture were derived from by-product of machinary culture, mass culture, internationalism, rapidly changing mode of various culture during industrial revolution. Industrial revolution was a change of the material world as well as in industry owing to machine advent, then the culture part that displayed directly these changes was the plastic arts of living that mould the material. The problem of clothing construction caused by industrial revolution was solved by pursuing the functional aesthetics. Clothing phenomenon as a process of value transfer participates mass culture in closs relation to general change of various culture caused by industrial revolution. Therefore western clothing gained the qualities of modern culture, condensed as function, and popularity in the process of modernization.

The purpose of this study is to explore the underlying causes of the development of private security in the United States. These include the increasing crime rates and fear of crime, the poor performance of public policing, the decentralization of political authority, the increase of mass private property, economic growth and increase of personal income, commodification of security, insurance companies' demand for tighter security and fear of litigation, and historical events such as World War I & II. Based on the findings of this study, it is suggested that no single factor would account for the growth of private security in the United States. In other words, the rapid growth of private security in the United States should be attributed to the interrelated influences of the factors given above. Finally, it might be the contribution of this study that the future development of private security in Korea would be guided by understanding the case of the United States because of the similarities of the developmental process in private security industry of two countries.

The purpose of this study is to investigate the developmental process of University-based librarianship education in Japan from a historical perspective by analyzing literature. The results show that America's librarianship education policy historically focused on the establishment of a new model of librarianship education whereas Japan's policy was to keep the one from the Second World War. In 1951, an American model of education was established at Keio University by the contract between U.S. Department of the Army and American Library Association in America, but it did not continue to develop as mainstream model. The American model of librarianship education was not successful in Japan. It is expected that this study concerning Japanese librarianship education which adopted by the American model at the first time after the war in Asia will give vision for further studies in the domain of library history.

Along with language, socialization is a unique feature of the human being. There is a continuous debate regarding whether the development of socialization is innate, and conducted by the environment in the growing process, or the result of the interaction of both aspects. If socialization is the result of the interaction with the environment or is an acquired developmental process, the following question rises. "Is there a 'critical period' for the development of socialization?" Although there are a huge number of studies seeking for treatment and solutions for developmental delay or deficits of socialization, it is very complicated question to answer. Historical figures such as 'Hugh Blair' of Borgue in England, and 'the wild boy of Aveyron' in France, seem to have innate socialization deficits. Nowadays patients with non-verbal learning disorder, social communication disorder, or autism spectrum disorder seem to have genetic defects. On the other hand, Harry Harlow's monkey experiments, hikikomori of Japan, Romanian orphans and patients with reactive attachment disorder seem to display social deficits due to environmental factors. However, it is not easy to clearly draw a line between innate or acquired factors. Therefore, rather than subdividing the diseases for etiological and pathophysiological approach to heterogenous groups with the common denominator of social deficit, and for the research of pathophysiology and treatment development, the authors suggest a comprehensive concept of "social dysfunction spectrum."

This study is about the law of cosines. It dealt with its historical origin and the developmental process of the age of Greece, Islam and Modern age. Especially, we tried to find out how the extension of the law of cosines for spherical triangles and tetrahedron from the law of cosines for plane was done. On the basis of this analysis, we investigated how the law of cosines was generated and proved it through the logical demonstration and mathematical induction. This made us find out the mathematical meaning of mathematical concepts.
