본 논문은 한국 근대수학교육의 아버지 이상설(李相卨, 1870-1917)이 자연과학―물리학―에 기여한 내용을 다루고있다. 이상설은 ?수리(數理)?를 쓴 시기를 전후하여, 같은 시기에 붓으로 총 8면에 걸쳐 『백승호초(百勝胡艸)』라는이름의 고전물리학 원고를 써서 남겼다. 분석결과 이 책의 원전은 1879년에 동경제대 의학부 교재로 발간된 『물리학(物理學)』이다. 이상설은 『백승호초』에서 먼저 개념을 정의하고, 일상에서 나타난 대표적 현상을 선록하여 한문으로번역하였고, 『물리학』의 전체 분량에서도 특히 ‘통유성(通有性)’에 중점을 두고 설명하였다. 동양에서 서양의 수리과학이 들어와야만 말할 수 있는 ‘질량보존의 법칙’, ‘타성(惰性, 관성)’과 같은 고전물리학의 중요개념을 포함하는 내용이 19세기 말에 이미 이 책에 소개된 것으로 보아 이상설은 당대의 다른 저술에서 보기 힘들 정도로 당시 일반물리학의 최고수준의 원서를 통해 최신 정보를 수용하고 전파하기 위하여 노력하였음을 볼 수 있다. 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.

李光洙 초기 단편소설의 모티프 양상연구

이상재 배달말학회 2004 배달말 Vol.34 No.-

이광수는 한국 현대 문학사에서 기념비적인 작가이다. 그의 초기 단편소설은 현대 문학의 출발이라는 의미 뿐만 아니라 그의 문학사상의 시발점이라는 점에서 중요한 의미를 지닌다. 그러나 이광수의 초기 단편소설은 연구자들에게 습작기적 수준이라고 폄하되거나 문학외적인 상황과 결부시켜 평가함으로써 그의 초기단편소설에 대한 면밀한 연구가 이뤄지지 않았다고 판단된다. 본고는 기존 연구자들의 연구태도를 지양하기 위한 방법으로 모티프가 소설로 형상화 과정을 고찰하고자 한다. 모티프를 통한 소설로의 형상화 과정을 고찰하면 이광수 단편소설이 지닌 형식적 특성 뿐만 아니라 논리적 전개 양상, 그리고 작품에 내재된 작가의식까지 고찰할 수 있다. 이광수 초기 단편소설의 모티프는 세 가지 양상으로 나타난다. 그 첫째가 구시대적 결혼의 고발이다. 「무정」, 「소년의 비애」, 「어린 벗에게」에서 살펴본 것과 같이 결혼의 모순이 가정에서 사회로 확대되고 있으며, 아울러 등장인물을 봉건적 의식에 사로잡혀 있는 여인에서 지식인으로 확대하여 보여줌으로써 결혼의 모순으로 인해 그 구성원들의 고통을 표현하고 있다. 둘째, 민족주의의 심화를 보여주었다. 1910년 한일합방 이전에 씌여진 「어린 희생」과 「헌신자」는 희생을 통해 민족애를 강조하고 있는 것으로 판단된다. 「어린 희생」은 침략민족에 대한 강한 저항정신을 담고 있는 반면 「헌신자」는 우리 민족의 자생적 성장이 교육에 달려 있다는 것을 보여준다. 셋째, 존재론적 고독과 탐색 과정이다. 이 소설군은 이광수의 자전적 색채가 어느 소설보다 강하게 드러나며 한일합방 이후의 상황에서 발표되었다는 점에서 한일합방에 대한 충격의 파장으로 보인다. 「김경」, 「방황」 그리고 「윤광호」에는 뚜렷한 방향을 잃고 방황하는 인물들이 등장한다. 그들은 한결같이 민족적인 삶에 회의를 가지고 자신의 자아를 찾으려한다는 점에서 목표가 상실되었을 때 나타나는 현상으로 이해된다. 이광수의 초기 단편소설은 근대소설로 나아가는 시발점에서 다양한 표현과 기법들이 드러나고 있다는 점에서 중요한 문학사적 의의를 지닌다. 또한 그것은 이광수의 문학적 생애와 사상의 변화까지도 보여준다는 점에서 중요한 의미를 지닌다. There is no doubt that Lee, Kwang-soo is a memorial author in history of Korean literature. His early shot stories are significant that they have some features of modern novels besides they are recognized as start line of Lee's literary achievement. However, the literati who has studied Lee's novels has been depreciating his works and analyzing them with relating non-literary aspects, which is definitely inappropriate to study literary material. This essay will be tracing the process which the motives of Lee's early shot stories is embodying the themes to evaluate objectively the significance of the shot stories. The concept of the motif which is selected as a method of this analysis is based on the motif theory of B. Tomashevsky. The motif of Lee's early shot stories is divided into 3 groups. The first motive is 'Marriage'. Lee, Kwang Soo kept talking about marriage in his stories written in 1910's. The stories about marriage are 'Cold-Heartedness(無情)', 'A boy's tear (소년의 비애)' and 'To my little friend(어린 벗에게)' and so on. These shout stories express how badly the antinomy of marriage out of date affect whole society. In addition, there are various characters in these stories to describe that the problems of marriage are occurring to all kind of stratums in society. They are evaluated that the quality is a little lower than his other works because there is something out of the themes which should be focused on marriage discovered. The second motif is 'Sacrifice'. These works were written before Korea became a colony of Japan , and one can feel Lee's patriotism through 'A young a sacrifice (어린희생)', 'Dedicator(헌신자)'. Lee is emphasizing antagonism against Japan and education for independent development of Korea. However, these stories have some defects which the author is equating patriotism and philanthropy and making readers confused by emphasizing parts which have nothing to do with 'Sacrifice'.The last motif is 'Solitude'. This demonstrates Lee's internal conflict after Korea belonged to Japan; 'Kim Kyung(김경)'', 'Wandering(방황)' and 'Yoon, Kwang Ho(윤광호)'. The characters of these stories are straying people, and they point the importance of individualism through showing conflict between nationalism and individualism. In other words, people have to overcome loneliness first. Lee, Kwang-soo's early works are very meaningful from a point of literary veiw because they were written with very close relation with the state of the day and make perceive the thoughts of the intellect. Moreover, there are some modern aspects discovered in Lee's early works.

본 원고는 2004년 과학사학자 박성래 교수가 독립 운동가이자 한국 근대 수학교육의 아버지로 부르기 시작한 보재 이상설(李相卨, 1870-1917)이 자연과학에 기여한 내용을 다루고 있다. 한국수학사학회지 2009년 11월 호에 자세히 소개된 〈數理〉를 쓴 시기를 전후하여, 같은 시기에 이상설이 붓으로 쓴 것으로 여겨지는 〈植物學>(이상설, 1899)은 총 4면의 초록 필사본이며, 그 대본(臺本)은 〈植物學啓蒙〉 (Edkins, 1886)으로 영국의 Joseph Edkins(艾約瑟, 1823-1905)가 번역하여 1886년에 간행한 〈西學啓蒙〉 16종 가운데 하나이다. 이상설의 〈植物學>은 이 〈植物學啓蒙〉을 읽으면서 그 책의 내용 중 당시의 조 선 학자가 모르고 있던 새로운 내용을 중심으로 메모를 한 것으로 여겨진다. 본 연구에서는 전통산학과 근대서양수학을 연결하는 〈數理〉를 저술했으며. 우리나라의 정규 교과과정에 수학과 과학을 필수과목으로 지정하고, 첫 번째 수학교과서 〈산術新書〉를 발간함으로 당대 최고의 수학자로 평가된 이상설이 쓴 〈植物學〉을 발굴하여 그 내용과 의미를 최초로 분석한다, 이를 통하여 당시 조선의 서양 과학, 특히 식물학에 대한 이해 수준을 분석하고 〈植物學〉의 원전인 〈植物學啓蒙〉 과 <西學啓蒙〉의 저자에 대하여 알아본다. 이는 당시 수학교육자가 자연과학분야에 행한 교육적 기여를 이해 하는데 필수적인 연구이다. 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.

The elastomeric impression materials had become increasingly popular. The purpose of this study was to evaluate the effect of thickness on the accuracy of the elastomeric impression materials. After impression trays were fabricated providing 1, 2, 3, 4, and 5mm spaces for the impression materials, the polysulfide, silicone, and polyether rubber base impressions were made with the brass master die and measured immediately and at 24 hours from the start of removal. Measurements were made of the length of the crossbar of a figure H reproduced in the impression fromthe scored surface of the occlusal aspect of the master die. The findings through this study could be summarized as follows: A this layer of elastomeric impression probuced more accurate results than thicker layer. Overall, the thickness on the accuracy of the elastomeric impressions did not produced significant differences between 1 and 3mm. In the polysulfide and the silicone impression, no sighificant differences were found in accuracy between 1 and 4mm immediately, and between 1 and 3mm at 2t 24 hours. at The polyether impression did not produced significant differences between 1 and 5mm. The polyether impression was the most stable, while polysulfide impression was the least stable dimensionally.

Pull-in behavior of second order phase locked loop(PLL) with a sinusoidal comparator has been investigated in the absence of noise. The approach is based on the fact that the unlocked behavior of first order PLL can be applied to the transient analysis of second order PLL. With this method, closed form expressions for the pull-in behavior and pull-in time of second order PLL have been obtained.

본 원고는 한국 근대 수학교육의 아버지 이상설(李相卨, 1870-1917)이 자연과학-화학-에 기여한 내용을 다루고 있다. 이상설은 "수리(數理)"를 쓴 시기를 전후하여, 같은 시기에 붓으로 총 46쪽에 달하는 "화학계몽초(化學啓蒙抄)"를 필사하였다. 분석해 본 결과 그 원전은 영국인 H. E. Roscoe(羅斯科, 1833-1915)가 1876년 발간한 Science Primers: Chemistry를 영국인 선교사 Joseph Edkins(艾約瑟, 1823-1905)가 번역하여 1886년에 간행한 "화학계몽(化學啓蒙)"으로 "서학계몽(西學啓蒙)" 16종 가운데 하나이다. Sang-Seol LEE wrote a manuscript HwaHakGyeMongCho(化學啓蒙抄) in the late 19th century. HwaHakGyeMongCho was transcribed from Science Primers: Chemistry (written by H. E. Roscoe), which is translated into Chinese by Joseph Edkins in 1886. LEE did not copy original writing exactly, but he understood the contents of each chapter and sections, then summarized and edited them in his caligraphic writing. In this paper, we introduce the contents for the first time and discuss the significance of this book.

In this paper, a Kalman filter utilized in the discrete system is designed and investigated. The parameters of the system are identified recursively by stochastic approximation using the gradient of the innovation sequence of the Kalman filter. The unknown parameters are replaced by their estimates on the Kalman filter. Stochastic approximation is simple, though convergence is slow. In this respect, a new gain sequence is introduced to accelerate the convergence rate.

One of the new trends in today's world economy is the emergence of increasing actviities of multinational corporations throughtout the world. The total number of foreign investors in Korea for the periods between 1962 and 1976 reaches almost one thousand, while their total value during the same period nearly approaches one billion in U.S. dollars. As their business activities extended beyond their national boundaries in various forms of foreign investment, it has become necessary to gather pertinent accounting information from foreign countries and to convey it to them as needed for the successful conduct of their world-wide business activities. The method of accounting has evolved over a long period of time as a practical technique in a specific context based on their own peculiar settings involving language, law, culture, politics, social and economic factors and the like. It is important, therefore, to understand the accounting systems of foreign countries which contain their respective accounting information so that the useful accounting information can be exchanged between these countries. It is with this objec ivetin view that the accounting systems of U.S., West Germany, France and Korea have been studied in this treatise. Chapter Ⅱ examines their legal rules and regulations on accounting, accounting standards, system, accounting theory and special problems arising from its practical applications. The main characteristics of their accounting systems are analysed and compared with one another in Chapter Ⅲ. The accounting system in the United States has developed from the stand point of investors and managers in line with the regulations set by the Security Exchange Commission (SEC) and under the leading opinions of the American Association of Accounting (AAA) and the American Institute of Certified Public Account (AICPA). In France it was developed and understood from the requirments of national economy, while closely regulated by the Law of Corporation and the Plan Comptable. Germany has developed its accounting system under its Law of Commerce which traditionally stresses the protection of an innocent third party. The development of accounting system in Korea has been unique in that its Law of Commerce was heavily influenced by the German Law of Commerce which is a part of the European continental legal system, while its Law of Security Exchange and it's accounting standards which directly affecting the practices of accounting affairs are under the direct influence of the American accounting system. As has been shown above, the accounting systems of these countries have developed in their unique fashion depending upon their own peculiar environments. However, it should be pointed out that it is the result of research conducted by the AAA and AIPCA which exerts the leading influenced upon the accounting practices of the world. In view of the recent move among the countries of the world to unify their accounting systems, it is hoped that this study will help to facilitate the conduct of international business activities throughout the world.
