Sang-Seol Lee(1870-1917) wrote a manuscript BaekSeungHoCho(百勝胡艸) in the late 19th century. BaekSeungHo-Cho was transcribed in classical Chinese from the 1879 Japanese book Physics(物理學) by Teizo Ihimori (1851-1916). Sang-Seol Lee, a famous independence activist, is also called Father of the Modern Mathematics Education of Korea,because of his early contribution to the modern mathematics education in the 19th century. In this paper, we introduce contents of his manuscript BaekSeungHoCho for the first time and discuss the significance of this book. Also, we show his constribution on the introduction to modern physics in the late 19th century Korea.

박영민 ( Young Min Park ),김채식 ( Chae Sik Kim ),이상구 ( Sang Gu Lee ),이재화 ( Jae Hwa Lee ) 한국수학교육학회 2011 수학교육논문집 Vol.25 No.2

This paper deals with contents that Sang-Seol Lee contributed to the natural science in the 19th century Korea. Prof. Sung-Rae Park, the science historian, called Sang-Seol Lee Father of the Modern Mathematics education of Korea. Sang-Seol Lee wrote a manuscript Botany with a brush in late 19th century. Botany was transcribed from Science Primers: Botany (written by J. D. Hooker), which is translated into Chinese by Joseph Edkins in 1886. The existence of Sang-Seol Lee`s book Botany was not known to Korean scientists before. In this paper, we study the contents of Botany and its original text. Also we analyze people`s level of understanding Western sciences, especially botany at that time. In addition, we study authors of 16 Primers for Western Knowledge. We study the contribution of mathematician Sang-Seol Lee to science education in the 19th century Korea.

조선시대 산서(算書) 연구 -규장각 소장 산서 연구의 분석을 중심으로-

이상구 ( Sang Gu Lee ),이재화 ( Jae Hwa Lee ) 한국수학교육학회 2011 수학교육논문집 Vol.25 No.1

HPM(History and Pedagogy of Mathematics) become an important issue to us now. Study on old Korean mathematics books were made recently. We study mathematics books in Kyujanggak in this article. Horng Wann-Sheng 洪萬生, an math. historian and a member of editorial board of Historia Mathematica, visited Kyujanggak, the royal library of Joseon Dynasty. After his visit, he published a paper, The first visit to mathematics books in Kyujanggak 奎章閣收藏算書初訪(2008 Kyujanggak 32, p. 283-293). In his paper, he also raised several research problems on the history of Korean mathematics. In this paper, we analyze his paper The first visit to mathematics books in Kyujanggak and give some answers to those raised problems on Korean mathematics. Also we correct some misunderstanding of Horng on some facts. Especially, we make it clear that the author of SinJungSanSul(New Arithmetics 新訂算術) was not Lee Sang-Seol(李相卨), whom Horng considered as the author, but Lee Gyo-Seung(李敎承) through the correct translation of its preface and an article about its copyright lawsuit. And we added some pathways how Chinese mathematics books were imported by Joseon. We introduce the case of Hong Dae-Yong(洪大容) in detail.

이상설 : 한국 근대수학교육의 아버지

설한국,이상구,Seol, Han-Guk,Lee, Sang-Gu 한국수학사학회 2009 Journal for history of mathematics Vol.22 No.3

Most who have heard of Sang-Seol Lee know him for his contribution to the Korean independence movement nearly a hundred years ago. This paper, however, will discuss Lee's other great contribution to his country; that of being "The father of modern mathematical education in Korea". Lee passed the rigorous government officer examination with the highest honor and became a teacher for the royal prince. Later he became the president of Sunkyunkwan, a national institute of higher learning since 1398, and eventually a well-known university bearing the same name. Lee was also a highly regarded Confucian scholar and well versed in foreign languages. He wanted Korea to become a modern country and felt that the areas of science and engineering were studies that needed improving in order to achieve modernization. While researching Western textbooks on the subjects he realized that Western mathematics would be especially important for Korea. With that, it became his mission to integrate Western mathematics into the Korean educational system. This paper will explain the importance of Sang-Seol Lee's contributions to mathematic education in Korea and how it helped Korea become the modern nation it is today.

이상구,홍성사,홍영희,Lee, Sang-Gu,Hong, Sung-Sa,Hong, Young-Hee 한국수학사학회 2009 Journal for history of mathematics Vol.22 No.4

17세기에 서양 수학이 조선에 들어온 이래 조선에 가장 큰 영향을 끼친 산서는 수리정온(數理精蘊)이었다. 19세기 말 조선에서 신교육이 시작되면서 수리정온(數理精蘊)이후의 서양 수학을 가르치게 되었다. 이 때 일본을 거쳐서 들어온 서양 수학은 주로 교과서로 나타난다. 이 논문은 독립 운동가로 잘 알려진 이상설(李相卨)의 저서인 수리(數理)를 조사하여 19세기 말 선교사를 통하여 서양 수학이 조선에 전해지는 과정을 알아본다. 특히 이상설(李相卨)이 조선 산학의 대수학 분야에서 중요한 변화와 발전을 이루어 낸 것을 밝혀낸다.

이상구,이상욱,김덕선,Lee, Sang-Gu,Ree, Sang-Wook,Kim, Duk-Sun 한국수학사학회 2008 Journal for history of mathematics Vol.21 No.1

In early 21st century, universities in Korea has been asked the new roles according to the changes of educational and social environment. With Korea's NURI and Brain Korea 21 project support, some chosen research oriented universities now should produce "teacher of teachers". We look 100 years back America's mathematics and see many resemblances between the status of US mathematics at that time and the current status of Korean mathematics, and find some answer for that. E. H. Moore had produced many good research mathematicians through his laboratory teaching techniques. R. L. Moore was his third PhD students. He developed his Texas/Moore method. In this article, we analyze what R. L. Moore had done through his American School of Topology and Moore method. We consider the meaning that early University of Texas case gives us in PBL(Problem Based Learning) process.

이상구 ( Sang Gu Lee ),이재화 ( Jae Hwa Lee ),변형우 ( Hyung Woo Byun ) 한국수학교육학회 2011 수학교육논문집 Vol.25 No.4

In 2007, a Taiwanese mathematics historian Wann-Sheng HORNG made a visit to Kyujanggak(the royal library of Joseon Dynasty) in Seoul, Korea. During this visit, he found the Korean math book An abridged version of the Joseon Mathematics (<數學節要>, Su-Hak-Jeol-Yo), which was written by Jong-Hwa AN(9 Nov 1860-24 Nov 1924) in 1882. Then he mentioned the possible importance of AN`s book in his article in the Journal Kyujanggak(vol. 32, June 2008). Jong-Hwa AN is a Korean scholar, activist of patriotism and enlightenment in the latter era of Joseon Dynasty. He passed the last examination of Joseon Dynasty to become a high government officer in 1894. The father of the modern mathematics education in Korea, Sang-Seol LEE(1870-1917) also passed the same examination with him. It is interesting that government high officer AN and LEE both wrote mathematics books in 19th century. In this talk, we now analyze this mathematics book of Joseon written in 1882.

최석정(崔錫鼎)의 산학연구와 ≪양와집(養窩集)≫의 저자 이세구(李世龜)

이상구,이재화,Lee, Sang-Gu,Lee, Jae Hwa 한국수학사학회 2015 Journal for history of mathematics Vol.28 No.2

In this paper, we give answers to some interesting questions about a Confucian scholar and mathematician in the late Joseon Dynasty, CHOI Seok-Jeong(崔錫鼎, 1646-1715), who was inducted into the Science and Technology Hall of Fame (http://kast.or.kr/HALL) for his mathematical achievements in October, 2013. In particular, we discover that CHOI Seok-Jeong was able to devote his natural abilities and time to do research on mathematics, and that he frequently communicated with his friend and fellow scholar, LEE Se-Gu(李世龜, 1646-1700), who was an expert on the astronomical calendar and mathematics, based on at least 24 letters between the two.

압전 단결정 재료를 이용한 이식형 인공중이용 적층 액츄에이터 개발

이상구,노용래,선주헌,Lee, Sang-gu,Roh, Yong-rae,Seon, Joo-heon 한국음향학회 2005 韓國音響學會誌 Vol.24 No.3

이식형 인공중이용 트랜스듀서는 주파수 특성 및 구동 성능이 우수해야 하고 크기가 작아야 한다. 이러한 트랜스듀서로서 단결정 압전 재료인 PMN-PT를 이용한 적층형 액츄에이터를 제안하였고, 유한요소해석 및 제작실험을 통해 그 타당성을 밝혔다. 실험에서는 두께 $0.2{\cal}mm$를 갖는 시편을 14층으로 쌓아 최종적으로 $1{\cal}mm{\times}1{\cal}mm{\times}2.8{\cal}mm$ 크기의 PMN-PT 적층형 액츄에이터를 제작하였다. 제작된 PMN-PT 액츄에이터의 성능은 Impedance Spectrum과 구동변위 측정을 통해 PZT 액츄에이터와 비교, 평가하였고, 이를 통해 단결정 재료인 PMN-PT를 이용할 경우 우수한 성능의 인공중이용 액츄에이터 제작이 가능함을 확인하였다. Transducers for implantable hearing aids need to be small and to have good performance in frequency responses and vibration properties. From this viewpoint, we Proposed a multi-layer actuator with the piezoelectric single crystal, PMN-PT. for the implantable hearing aid. and verified its adequacy through finite element analyses and experiments. PMN-PT multi-layer actuator samples were fabricated by stacking fourteen layers of the PMN-PT crystal. Each layer were $0.2{\cal}mm$ thick and the actuator sample was $2.8{\cal}mm$ thick in total. We evaluated the performance of the PMN-PT actuator through impedance analyses and vibration displacement measurements, and compared the result with that of a PZT actuator. Results of all the process confirmed the feasibility of the PMN-PT actuator as a good transducer for an implantable hearing aid.

Oswald Veblen이 미국수학계에 미친 영향과 한국에서의 의미

이상구,함윤미,Lee, Sang-Gu,Ham, Yoon-Mee 한국수학사학회 2009 Journal for history of mathematics Vol.22 No.2

This article discusses the contributions of the leader Oswald Veblen, who was the president of AMS during 1923-1924. In 2006, Korea ranked 12th in SCIE publications in mathematics, more than doubling its publications in less than 10 years, a successful model for a country with relatively short history of modern mathematical research. Now there are 192 four-year universities in Korea. Some 42 of these universities have Ph.D. granting graduate programs in mathematics and/or mathematical education in Korea. Rapid growth is observed over a broad spectrum including a phenomenal performance surge in International Mathematical Olympiad. Western mathematics was first introduced in Korea in the 17th century, but real significant mathematical contributions by Korean mathematicians in modern mathematics were not much known yet to the world. Surprisingly there is no Korean mathematician who could be found in MaC Tutor History Birthplace Map. We are at the time, to have a clear vision and leadership for the 21st century. Even with the above achievement, Korean mathematical community has had obstacles in funding. Many people thinks that mathematical research can be done without funding rather unlike other science subjects, even though they agree fundamental mathematical research is very important. We found that the experience of early American mathematical community can help us to give a vision and role model for Korean mathematical community. When we read the AMS Notice article 'The Vision, Insight, and Influence of Oswald Veblen' by Steve Batterson, it answers many of our questions on the development of American mathematics in early 20th century. We would like to share the story and analyze its meaning for the development of Korean Mathematics of 21st century.
