In this study, we explored the role of analysis in the algebra development. For this, we classified ancient geometric analysis into an analysis by reduction and a Pappusian problematic analysis. this shows that both analyses have the function of reduction. Pappus' analysis consists of four steps; transformation, resolution, construction, demonstration. The transformation, by which conditions of given problem is transformed into other conditions which suggest a problem-solving, seems to be a kind of reduction. Mathematicians created new problems as a result of the reductional function of analysis, and became to see mathematics in the different view. An analytical thinking was a background at the birth of symbolic algebra, the reductional function of analysis played an important role in the development of symbolic algebra.

In this paper, we survey the development of material implication and we present an analysis of the students' understanding of formal implication. Most of high school students consider material implication $p{\rightarrow}q$ as ${\sim}p{\vee}q$ when they represent the pattern of a collected cards as material implication $p{\rightarrow}q$. But when they collect cards in which material implication $p{\rightarrow}q$ is true, Most of high school students consider $p{\rightarrow}q$ as $p{\wedge}q$.

By comparing the development history of rectangular coordinate system in Cartography and Mathematics, we assert in this manuscript that the rectangular coordinate system is not so much related to analytic geometry but comes from the space perceiving ability inherent in human beings. We arrived at this conclusion by the followings: First, although the Cartography have much influenced to various area of Mathematics such as trigonometry, logarithm, Geometry, Calculus, Statistics, and so on, which were developed or progressed around the advent of analytic geometry, the mathematical coordinate system itself had not been completely developed in using the origin or negative axis until 100 years and more had passed since Descartes' publication. Second, almost mathematicians who contributed to the invention of rectangular coordinate system had not focused their studying on rectangular coordinate system instead they used it freely on solving mathematical problem.

최근 컴퓨터의 급속한 보급과 영상처리기술의 발달로 금석학 분야는 인문학의 범주를 뛰어넘어 문화 정보 공유의 중요한 위치로 자리매김하게 되었다. 본 연구는 국내에서 처음 시도 되는 것으로, 수천년 정신문화 산물의 정보자료인 탁본을 영상으로 입력하여 디지털 데이터로 전환하고, 이를 공간 영역에서 종합 분석함으로 탁본영상 고유의 특성을 파악하고자 하였다. 탁본 원영상은 흑백의 두 영역으로 분할되는 완벽한 이진영상이나, 탁본뜨기 수작업과정을 거치면서 관측영상에는 영역간 색도의 혼재가 발생하고 얼룩무늬와 문양이 전체 영상에 분포한다. 이와같은 영상으로부터 필요한 문자나 문양의 정보를 추출하기 위한 전단계로 영상에 관한 종합적인 분석 작업을 하였다. 분석 기법으로는 공간분석법을 사용하였다. 역사적으로 유명한 대표적인 탁본을 위시하여 40여개의 탁본영상 샘플을 무작위로 선택하였고, 공간분석을 통해 색도분포특성과 영역간 색도 중복 및 영역형성 양상과 특성을 찾아내었다.

The primary aim of this paper is to discuss the historical development or grammaticalization of English adverbial -ly suffix and provide a diachronic analysis of manner adverbs and sentence adverbs from the perspective of secondary grammaticalization. The grammaticalization includes both the primary grammaticalization from a lexical to a grammatical and the secondary grammaticalization from a less grammatical to a more grammatical status. The emergence of the manner adverbs is due to the primary grammaticalization from OE adjectival suffix -lic to ME adverbial suffix -ly. In contrast, the emergence of sentence adverbs is due to the secondary grammaticalization from manner adverbs in VP domain to sentence adverbs in TP domain with grammatical features of tense and modality. This paper concludes that the secondary grammaticalization of the English adverbial -ly suffix includes the change from manner adverbs to sentence adverbs which obtain a new grammatical function of tense and modality.

This thesis is the study of the effects of Korea and China to Japan's moxibutsion formation historically and the process of Japan accepting and systemizing these effects. The method to the study is to organize the features and developments of Korea, China and especially Japan periodically by focusing on literature. Japan had traveled through China and Korea to resolve the medical problems in Japan and established a traditional medical system by interacting medical technology and publications. Korea had made a tremendous role in developing Japan's traditional medical development by accepting and making a system to China's advanced medical knowledge and books to spread these to Japan. However, Japan is the most developed from those three country for moxibustion. Through the studies of Japan's moxibustion culture and the process of the development, this thesis will present methods of development and recognition to our own traditional medicine of moxibustion.

철도(鐵道)의 역사는 레일(rail)의 발달로부터 시작되었다고 한다. 철도(鐵道)는 그 발상지인 영국에서 railway(미국 : railroad, 프랑스 : Chemins do for, 독일 : Eisenbahn, 네덜란드 : Spoorweg, 이탈리아 : Ferrovia, 스페인 : Ferrocarril, 중국 : 鐵路)라고 불려지고 있다. 이것을 직역하면 "레일 길(rail 道)"로 된다. 이 단어가 나타내는 것처럼 간단하게 말하면, 철도란 레일의 위를 달리는 교통기관이며, 철도에 있어 레일은 가장 중요하고 불가결·기본적인 부재이다. 따라서, 레일은 철도의 심볼이라고 할 수 있다.

교육학의 질적 연구는 문헌 연구, 면담 연구, 비참여 관찰 연구, 참여 관찰 연구로 분류한다. 문헌연구에는 내용분석, 철학적 연구, 역사학적 연구, 문학적 비평이 들어가고, 면담연구에는 구술사, 전기, 탐문(探問) 저널리즘 등이 포함되고, 비참여 관찰연구에는 전문적 감정(鑑定), 인간의 종적 특성 연구, 관찰자 연구, 비개입적 행동 연구 등이 포함된다. 마지막으로 참여 관찰연구는 일반적 현장연구, 문화 기술적 연구가 포함된다. 질적 연구는 사람, 사물, 현상의 범주화나 수량화가 가해지기 이전의 상태, 즉 '있는 그대로'의 상태에 최대한 접근하는 방법으로써, 고정관념을 깨고 기존의 이론을 최대한 유보한 채 연구에 임하는 것으로 최근에 발달한 인문사회과학적 연구방법이다. 질적 인식이 자연언어에 주로 의존하는 데 비해 양적 인식은 인공언어에 많이 의존한다. 수식과 도형, 부호등은 대표적인 인공언어이다. 모든 사물이 질과 양의 속성을 다 가지고 있듯이 모든 연구는 질적 과정과 양적 과정을 다 포함하고 있다. 질적이냐, 양적이냐 하는 구분은 연구방법론의 문제인데 연구방법론은 연구논리와 연구기법을 포함한다. 본 연구는 인공언어인 수와 식에만 익숙한 수학교육에서, 질적 연구가 왜 필요한지, 어떤 특성이 있는지 논의함으로써 수학교육의 새로운 방법론을 제시하고자 한다.

The ${\ulcorner}$Dae${\lrcorner}$ is a place where a man could commune with nature. Our ancestors, who had very interested in natural landscape, and were named to the typical rock in the nature, which they called 'Dae'. The results of a analyzed the old literature(1530 : early stage of Chosen Danasty) are as follows. 1. The distribution of Dae is differ from provinces. Gangwon-do, Kyongsang-do, Cholla-do had many of the Daes. 2. The characteristics of form were classified into five groups. 1) A type of huge flat rock, which able to sit 5-6 persons(30.2%) 2) A type of mountain peak, which unable to use but seems to use images (27%) 3) A type of cliff(25.4%) 4) A type of fantastic rock (9.5%) 5) A type of stratified rock (6.3%) 3. The behavioral characteristics of the Dae were summarized watching a scenery and strolling (유(遊)), enjoying acenery, and relaxation. 4. The site locations of Dae are various such as, hill top, on cliffs, on the mountain, around river, river side cliff or grand rocks, and so forths.
