This paper proposes to examine how herbal medicine studies developed amidst the historical changes, by studying the publications of herbal medicine books. For this reason, centering on the most eminent herbal medicine books of each period, the characteristic of the times shown by their publication and the development of herbal medicine were summarized. Also, traces of herbal medicine books among the eminent classics that were imported into our medicine and made a deep impact, and whether or not a Chosun edition was published were researched and introduced in order to show the influence it had on Korean Medical History.

To introduce materials related to our traditional mathematics and to reinterpret modernly them could be a good tool to find the cultural values of them. We analyzed the degree for utilization of the history of mathematics in the middle school textbooks developed depending on the 2009 revised mathematics curriculum. Through this, we suggest the need for research on concrete and practical teaching and learning materials development utilizing the history of mathematics. We reinterpret, in modern style based on the curriculum, two subjects dealt with in 'GakDeungByeonHyeongSeupYu', the first theme of 'SanSulGwanGyeon' written by Lee Sang Hyuk. We expansively reconstruct the original samples up to regular decagon so that students might figure out the situation of all regular polygon using a kind of mathematics software GeoGebra. Also this process is constructed on the basis of the curriculum for an implementation the secondary school classes.

In the present study, we review the history of the participations of the Korean national team in the International Mathematical Olympiad for 28 years. We identifiy three major events that highlighted the development of the Korean Mathematical Olympiad program: The first participation in the International Mathematical Olympiad, hosting of the International Mathematical Olympiad, and winning the first place in the International Mathematical Olympiad. We also propose some recommendations for next steps to facilitate the development of Mathematical Olympiad in Korea.

Recently industry goes through enormous revolution. Related to this, major changes in applied mathematics are occurring while coping with the new trends like machine learning and data analysis. The last two decades have shown practical applicability of the long-developed mathematical theories, especially some advanced mathematics which had not been introduced to applied mathematics. In this concern some countries like the U.S. or Australia have studied the changing environments related to mathematics and its applications and deduce strategies for mathematics research and education. In this paper we review some of their studies and discuss possible relations with the history of mathematics.

Through researching 鄕藥救急方, the oldest medical text published in Korea in existence known to date, a study from a Traditional Korean Medicine perspective was conducted. This study aims to observe the treatment of oral, glottal, labial, and dental diseases starting from 統一新羅時代 to the Koryo dynasty from a historical perspective and also find out what clinical significance it withholds. "鄕藥救急方" proposes methods of nurturing the teeth and in doing so displays the tendency of Traditional Korean Medicine of putting much weight on preventing diseases and nurturing the body. "鄕藥救急方" considers the oral, glottal, labial, and dental diseases as not only fundamental problems in itself but also treats them from a perspective that they are results of disharmony among the five viscera and the six bowels. The treatment methods mentioned in "鄕藥救急方" are directly cited in "鄕藥集成方" of early Chosun dynasty. In "東醫寶鑑" of mid-Chosun dynasty, however, changes and modificatios are made to the prescriptions.

For attempting to wright a history of Modern Architecture in Korea the first task might be to establish the beginning of the period and to search for the orign of Modernity in Korean Architecture. As a member of the third world Modernism and Modernity in Korean Modern architecture has to be different from that of the West. The main purpose of this study is to define Modernity and to find out the characteristics of Modernism in Korean architecture. Above all this study suggests to note the peculiarity and the differance in the history of Modern architecture within the large frame of modernization. Then maintains that the search for the new cultural identity and rationality instead of lost tradition and convention can be defined as a modernity in Korean architecture.

Ultra-high-performance concrete (UHPC) consists of cement, silica fume (SF), sand, fibers, water and superplasticizer. Typical water/binder ratios are 0.15 to 0.20 with 20 to 30% silica fume. In the production of ultra-high performance concrete, a significant temperature rise at an early age can be observed because of the higher cement content per unit mass of concrete. In this paper, by considering the production of calcium hydroxide in cement hydration and its consumption in the pozzolanic reaction, a numerical model is proposed to simulate the hydration of ultra-high performance concrete. The heat evolution rate of UHPC is determined from the contributions of cement hydration and the pozzolanic reaction. Furthermore, by combining a blended-cement hydration model with the finite-element method, the temperature history in the hardening of UHPC is evaluated using the degree of hydration of the cement and the silica fume. The predicted temperature-history curves were compared with experimental data, and a good correlation was found.

Buddist Medicine has greatly influenced Chinese medicine, a medicine centered around East Asian traditional medicine. Buddhist medicine, however, was replaced when Chinese medicine became centered around Confucianism in the 12th century. According to "Tianjinyaofang" a document of the 8th century, however, traces of Buddhist medicine can be found. This study has found and organized the traces of Buddhist medicine in both Korean and Chinese medicine today.

T-history method, measuring heat-of-fusion of phase change material (PCM) in sealed tubes, has the advantages of a simple experimental device and no requirements in sampling process. However, a degree of supercooling used in selecting the range of latent heat release and neglecting sensible heat during the phase change process can cause significant errors in determining the heat of fusion in the original method, which has been improved in order to predict better results by us. In the present study, the modified method was applied to a variety of PCM such as paraffin and lauric acid having very small or no supercooling with a satisfactory precision. Also the selection of inflection point and temperature measurement position was fumed out not to affect the accuracy of heat-of-fusion significantly. As a result, the method can provide an appropriate means to assess a new developed PCM by cycle test even if a very accurate value cannot be obtained.

In this study, we examine Maeng Hwa-seop's academic activities, focusing on articles published in Uirim, JKM (Journal of Korean Medicine), and other branch journals which were affiliated with the Society of Korean Medicine. The present study charts and summarizes the papers published in the above journals. By organizing Maeng Hwa-seop's papers and making tables, we find that his research can be divided into four categories: symptoms and diseases, prescriptions, academic presentations, and translations of medical literatures. Based on this study, we hope that further researches about the academic activities of Maeng Hwa-seop can be conducted in the future.
