The aims of the study were to review the transcriptions of the famous cuneiform tablet 'Plimpton 322' and interpret the meanings of the numbers. Since the tablet was found, many scholars tried to interpretate the relation among numbers. Neugebauer & Sacks, Buck, and Robson's finding are reviewed. This tablet must be the most well known and taken as an important role to complete a proof of the Pytagoras' theorem before the development of Greek Mathematics.

The thesis is about the development of mathematics starting from the old Greece and the old Babylonia. The modem mathematics has been developed, based on the set theory in the axiomatic method since the 19th century. The primary impetus of this thesis will be to summary the development of topology.

Many researchers consider the totality of Babylonian mathematics was profoundly elementary, but some of their mathematical knowledge achieved a novel comparable to the Greeks. The aim of this article is to provide a brief overview of the environmental and social background which made mathematical development. Historically, mathematics is always a product of society. So it is valuable to study historical background which have produced mathematics.

In this paper, we study the major mathematical history appeared in the elementary school mathematics textbooks. School mathematical history described in the texts reflects the axial age, and deals with mathematical transculture from the ancient Greek into Europe without the Islamic mathematics. We discuss about them through out the elementary school textbooks and give some directions for the problems.

(Brazing)에 의한 금속의 접합기술은 이미 BC 3000년경 고대 바빌로니아(Babylonia)에서 귀금 속의 장식품을 만드는데 에 이용되어져 왔다. 근대에 와서는 1950년 후반 N.Redns등의 탄소강의 Ag브레이징을 개발한 이후부터 브레이징에 관한 연구가 활발하게 되었다. 즉, 삽입금속 및 플 락스의 개발, 삽입금속과 모재의 젖음성, 브레이징의 강열법과 분위기 조절, 접합이음부의 설계 등에 대해서 계통적인 연구가 시도되었다. 그 결과, 최근에 이르러서는 스테인레스 파이프의 금브레이징에 의한 로켓트부스타(Rocket Booster)의 제작, LSI의 프린터배선, 파인 세라믹스와 금속을 브레이징하여 소형 자동차의 Turbo Charger Rotar의 제작등에 이용되고 있고, 첨단기 술에 없어서는 안될 중요한 접합기술로 주목을 받고 있다. 선진국에서는 많은 연구 개발의 성 과로 고부가가치 제품의 생산에 활용되고 있지만, 현재 국내에서는 1950년대의 기술수준에 있고, 연구 개발에 대한 업계 및 학계의 관심의 부족하기 때문에 기술축적은 전혀 되어 있지 않다. 특히, Brazing에 관련된 자료나 기초지식을 습득하기 위한 교재도 출판된 것이 없고, 번역된 전문 서적도 구하기가 힘들기 때문에 브레이징 기술에 대한 인식도 낮고, 적재적소에 활용도 되지 않고 있는 실정이다. 이와 같은 배경 하에서 저자들은 브레이징에 대해서 관심을 가지는 회원 들에게 조금이나마 도움을 주고자 외국에서 출판된 서적 및 논문 등을 참고로 하여 정리하여 브레이징의 기초와 실제라는 제목으로 4회에 걸쳐서 게재하고자 한다.

The purpose of this article is to discuss some of the most commonly repeated misconceptions on the history of mathematics described in the secondary school mathematics textbooks, and recommend that we should include mathematical transculture in the secondary school mathematics. School mathematical history described in the texts reflects the axial age, and deals with mathematical transculture from the ancient Greek into Europe excluding the ancient Egypt, Old Babylonia, and Islamic mathematics. We discuss about them through out the secondary school textbooks and give some alternatives for the historical problems.

The Mesopotamia civilization is developed by physical geography. It began from Sumer civilization at BC 3800 and finished to Assyria and Babylonia civilization at BC 600. Therefore, to examine the changing process of the city of 3,000 years standing, it is important to know the elements of the influence to the initial human civilization and city. This study analyzed the 13 cities, that the city were among the 30 the city in same age. As a result of this study, firstly, functions of the city were gradually transition from the farming culture to the functions of commerce, trade, and military. Secondly, the location of the city was gradually move into northern from southern, it is associated with features of the city. Thirdly, the aspect of urban form, the hills above the city of Tel's shape was gradually coming down to the plains. So later, became a form of urban planning undisturbed terrain. fourthly, urban structure has slowly changed from the temple based city to palace based city.

Until the 1950s, linear algebra was considered only as one of abstract and advanced mathematics subject among in graduate mathematics courses, mainly dealing with module in algebra. Since the 1960s, it has been a main subject in undergraduate mathematics education because matrices has been used all over. In Korea, it was considered as a course only for mathematics major students until 1980s. However, now it is a subject for all undergraduate students including natural science, engineering, social science since 1990s. In this paper, we investigate the early history of linear algebra and its development from a historical perspective and mathematicians who made contributions. Secondly, we explain why linear algebra became so popular in college mathematics education in the late 20th century. Contributions of Chinese and H. Grassmann will be extensively examined with many newly discovered facts.

In this paper, we examine how secondary school mathematics textbooks on calculus introduce the history of calculus. In order to identify the problem, we consider the Babylonian integration by trapezoidal rule, which was made to calculate the location of Jupiter in 350-50 B.C., and the integration by the method of the rotating plate of ibn al-Haytham in Egypt, about 1000 years. In conclusion, our secondary school mathematics textbooks describe Newton and Leibniz as inventing calculus and place their roots in ancient Greece. The origin of the calculus is in Babylonia and the Faṭimah Dynasty (909-1171) (Egypt) and it is desirable that the calculus is developed in Europe after the development of the power series in India, and that the value of Asia Africa is introduced in the textbooks.

The purpose of this paper is to illustrate the nature of Objective Psyche based on island related case materials. Theoretical background starts with psychological meaning of islands, a kind affective symbol rather than cognitive image, and creation myths as the story of man's awareness of the world; Chaos as archaic identity (unconscious), islands as emergence of the ego from unconscious. In alchemical symbolism, island related to coagulatio, the operation which turns something into earth, the realm of ego. In addition, related parts of Hindu creation myths, Korean giant woman creator Sulmoonde-halmang, and legends of "Relocation of Island/Mountain" will be presented to integrate with case materials. Case A : Starts with a dream of killing a huge dragon and dead body became an island. The dragon in the water was seen as Spirit of Mercurius, the autonomous spirit, connecting of the ego with the Self. The act of killing related to Primeval being which needs to be killed to be transformed. Myths of Eskimo, The Eagle's Gift, the giant woman creator in Korea, and Marduk, the Babylonian hero will be integrated. Case B : Prior to introduce six island images in sand trays, a dream of a giant serpent (python) wound around her body will be presented to portray her situation. By relating Jung's "The Sermons to the Dead," her effort to make the solid island regarded as an act of bringing order out of original oneness (pleroma). Then stresses the importance to coagulate archetypal image Case C : A vignette of active imagination seminar where island image emerged will be described. Her endeavor of focusing on inner image related to the Hindu Creator, Cherokee creation myth, as well as Sulmoonde-halmang. As a motif of growing island, Samoan creation myth, and Legend of Mountain, Mai were incorporated. Colors in her art work regarded as expression of inner need, and importance of expressing inner feeling images as a mean to coagulate volatile emotional and spiritual content. Case D : A dream and art work of terminally ill woman; embracing the tip of the island with gushing up water will be presented. Her island and replenishing water image regard as "an immortal body," corresponds to the Philosophers' Stone for she accepted her death peacefully after the dream. Also related to "The Mercurial Fountain" in Rosarium Philosophorum, and aqua permanence, an allegory of God.
