Objectives : I'd like to introduce a Korean medical scientist, Lee Gyoojoon (李圭晙, 1855-1923)'s achievements about Huangdi's Internal Classic (黃帝內經, HIC) to examine the Section of Viscera and Bowels to inspect the Medical Classics (稽經藏府篇, SVBIM) of the Double grinded Medical Mirror (醫鑑重磨, DMM), which is a medical book published in 1922, his last studies. And I'd like to describe its meaning of medical history. Methods : For this, I compared the DMM with two primary texts, the representative medical books of Joseon dynasty, Treasured Mirror of Eastern Medicine (東醫寶鑑, TMEM) and Lee's former research result of HIC, Major Essentials of Huangdi's Internal Classic Plain Question (黃帝內經素問大要, MEHIC), in the aspects of the original text, annotation, editing, attached theses, and so on. Results : Lee Gyoojoon criticized the TMEM in two aspects. First, it was unfocused and miscellaneous, second, it intended to help Yin Qi (陰氣) and reduce Yang Qi (陽氣) so that it regards a prime mover, Yang Qi, as an enemy. In order to solve these problems he deleted miscellaneous articles and sort out the points to accord with the HIC. As a result, he had written the Section of SVBIM of the DMM in the form of revising the subtitles or refuting the contents of TMEM and quoted the partial texts of MEHIC to be written by the view of Supporting Yang Qi (扶陽). Conclusions : Lee Gyoojoon proposed the Supporting Yang Qi medicine to preserve the Heart fire (心火) based on his lifelong Neo-Confucianism (性理學) study. The Section of SVBIM of the DMM showed how to apply his medical theory, which is achieved by the study of the medical classic HIC to real clinical medicine through a medium of the TMEM. In addition, it could explain concretely how the Confucianists studied the medicine and how Confucianism can impact to the development of medical theory.

The 18th century Joseon(朝鮮) science philosopher Hong Dae-Yong(洪大容, 1731-83) tried to create his own scientific system, while partially keeping the Eastern view of nature and accepting Western science and technology. Most of all, he confirmed that Western science and technology was based on mathematical principles and accurate observation and wrote a math book, [Juhaesuyong(籌解需用)]. Therefore, we have good reason to call him a mathematician. He produced so many achievements that he can be considered a natural scientist in the late Joseon era; he accepted the Eastern view of nature critically and sometimes refused it. He also suggested new and various scientific thoughts, including an infinite universe theory, on the basis of Western scientific thought. Hong Dae-Yong emphasized the importance of practice. He understood the principle of the Western Honcheonui(渾天儀) and manufactured an alarm clock with a craftsman's help. He was an excellent engineer and he set a personal observatory. Considering the level of scientific technology at that time, it is reasonable to regard Hong Dae-Yong as a 'scientific technologist in the 18th century Joseonera', well equipped as a mathematician, a natural scientist, and an engineer. In conclusion, it is with 'mathematical thinking, creative conception, and practical activities' that Hong Dae-Yong maintained throughout his life that we can set a guide to produce excellent Korean scientific technologists and engineers in the 21st century.

With increasing interest on scientists and the influence of science technology, their role in the modem society has been expanding. Scientists work in the laboratory as researchers, work in their expertise area as professionals, and work socially as social agents. Scientists are responsible to keep up the regulations during the research, and also are responsible for the results of the research. Therefore, there is a need of contemplation in terms of what their identity is and what their responsibilities are. Despite of this need, there hasn't been much discussion or education on the scientists social role or responsibilities as of now. This study purported to contemplate on the scientists role and responsibility, its qualification, and what it means to be a scientist as a social agent. Also the study further explored the efficient educational strategies and methods relevant to the contemplated issues.

Massive increases in data available to an organization are creating a new opportunity for competitive advantage. In this era of big data, developing analytics capabilities, therefore, becomes critical to take advantage of internal and external data and gain insights for data-driven decision making. However, the use of data in education is in its infancy, in comparison with business and government, and the potential for data analytics to impact education services is growing. In this paper, I survey how universities are currently using education data to improve students' performance and administrative efficiency, and propose new ways of extending the current use. In addition, with the so-called data scientist shortage, universities should be able to train professionals with data analytics skills. This paper discusses which skills are valuable to data scientists and introduces various training and certification programs offered by universities and industry. I finally conclude the paper by exploring new curriculums where students, by themselves, can learn how to find and use relevant data even in any courses.

In order to apply AI (Artificial Intelligence) in various industries, interest in algorithm selection is increasing. Algorithm selection is largely determined by the experience of a data scientist. However, in the case of an inexperienced data scientist, an algorithm is selected through meta-learning based on dataset characteristics. However, since the selection process is a black box, it was not possible to know on what basis the existing algorithm recommendation was derived. Accordingly, this study uses k-means cluster analysis to classify types according to data set characteristics, and to explore suitable classification algorithms and methods for resolving class imbalance. As a result of this study, four types were derived, and an appropriate class imbalance resolution method and classification algorithm were recommended according to the data set type.

Rice varietal information exchange is vital for agricultural experiments and trials. With the growing size of rice data gathered around the world, and numerous research and development achievements, the effective collection and convenient ways of data dissemination is an important aspect to be dealt with. The collection of this data is continuously worked out through various international cooperation and network programs. The problem in acquiring this information anytime anywhere is the new challenge faced by rice breeders, scientist and crop information specialists, in order to perform rapid analysis and obtain significant results in rice research, thus alleviating rice production. To address these constraints, we propose an Online Analytical Query System, a web query application to provide breeders and rice scientist around the world a fast web search engine for rice varieties, giving the users the freedom to choose from which trial it has been used, trait observation parameters as well as geographical or weather conditions, and location specifications. The application uses data warehouse techniques and OLAP for summarization of agricultural trials conducted, and statistical analysis in deriving outstanding varieties used in these trials, consolidated in an Model-View-Controller Web framework.

The Korean genetics and genomics reveal a firm willingness to participate in and contribute to the production of creative scientific knowledge at a world level at present, though they have short past histories of introduction from the Western counterparts and those of education for the next generations. But the Korean genetics and genomics have been developed in a fragmented and biased manner. By reconfiguring the various research projects of genomics into the Genome Project of Korea, which reflect a worldly trend in life science, but have been established in a scattered fashion in Korea, and incorporating some neglected areas of genetics, such as human genetics and theoretical and population genetics which can be reconstructed in a new way, a genetics-genomics research system can be formulated on the multi-tiered perspective of concept, knowledge, and institution, while the system being a subsystem of the national research system of life science in Korea. Innovation can be pursued in the systematic practice through a culturalist strategy. The culturalist strategy with the practice based on the research system consists of 1) intensification of fundamentalness of genetics and genomics, 2) advancement of communitarianism in geneticist-genomicist community, 3) research on the cultural bio-species along with the promotion of scientific arts and culture, and 4)formation of the Korean science studies of genetics-genomics and the diffusion of the knowledge produced. The first two strategy components are the ones that intends to bring out changes in the structural aspect of the scientist community in Korea. The third is the one that attempts to magnify the interface between the scientist community and the Korean society at large and increase its connectivity between both, while the fourth is the one that has an intentionality toward the Korean society outside of the scientist community. This culturalist strategy is intended to increase the cultural constructivity of the genetics-genomics research system in Korea.

This review examines computational simulations of thermoelectric properties, such as electrical conductivity, Seebeck coefficient, and thermal conductivity. With increasing computing power and the development of several efficient simulation codes for electronic structure and transport properties calculations, we can evaluate all the thermoelectric properties within the first-principles calculations with the relaxation time approximation. This review presents the basic principles of electrical and thermal transport equations and how they evaluate properties from the first-principles calculations. As a model case, this review presents results on $Bi_2Te_3$ and Si. Even though there is still an unsolved parameter such as the relaxation time, the effectiveness of the computational simulations on the transport properties will provide much help to experimental scientist researching novel thermoelectric materials.

The pH value of grass silages is one important parameter to determine the quality of the forages. In an attempt to use NIRS spectra taken for other quality parameter of grass silage it has been shown that a good correlation between NIR spectra of the dried forage and pH value of the fresh forage could be determined. Further investigations revealed that the B coefficients of the pH value calibration were almost the same as the B coefficients of the sugar calibration multiplied with -1. And indead the pH value - in the fresh sample material - of the calibration set is strongly correlated with the sugar concentration - in the dried sample material. It is concluded that next to scientific tools in research the scientist and the user of NTRS equippment has to scrutinze his own work. Examples are given. NIRS is a powerfull technique, but pitfalls are present in surplus.

The TRIZ theory which was invented by Russian scientist Genrich Altshuller provides a systematic methodology for innovative engineering design in place of brainstorming. synectics, analogical thinking, which seeming1y high efficiency are still variations of the trials and errors method. TRIZ theory gives designer the ability to explore design solutions in fields other than his (her) own experience. Among several TRIZ theories, most widely used techniques in engineering field are contradiction theory. Su-Field analysis, physical phenomenon and effect and directed production evolution. which are described in this thesis and its application to conceptual design of high-speed train is performed as a case study of TRIZ theory.
