In this article we studied one of the greatest mathematicians and pedagogues, A.N. Kolmogorov. He wrote about five hundreds o( books and articles in the fields of pure mathematics and mathematics education. In this paper we in detail introduced Kolmogorov's history of mathematics education and his theory of mathematical abilities, and elaborated this theory. In addition, we suggested some materials which are aimed to develop mathematical abilities in correspondence to the theory of Kolmogorov.

In this paper, we take the survey through both papers and recent reports to investigate points to be considered in developing the national mathematical curriculum. Then we suggest that to prepare the next national mathematical curriculum, we consider the method to deduce the math-dislike, the method to increase the power of problem solving etc. and also we construct a compact curriculum which contains most of important math items. In the process of developing the curriculum, we must have lively discussion with mathematicians, and especially with teachers.

우리나라의 영재 교육 기관에서는 우수한 인재 양성과 이공 계열 기피로 인해 발생한 이공계 위기를 해결하기 위해 융합인재교육(STEAM)을 포함하여 다양한 융합형 교육을 시행하고 있다. 이 연구의 목적은 융합형 교육을 시행하고 있는 대학 부설 과학영재교육원 소속 영재 학생들의 과학, 수학 및 기술/공학 영역에 대한 인식을 조사하는 것이다. 연구 대상은 영재교육원 소속 중학교 영재 학생 86명이며, 3개 영역의 97문항으로 구성된 검사지를 활용하여 자료를 수집하였다. 연구 결과를 정리하면 다음과 같다. 첫째, 중학교 영재 학생들은 수학이나 기술/공학보다 과학을 흥미롭게 생각하고 있었으며, 둘째, 진로 선택에서도 과학 영역이 높게 나타났다. 셋째, 과학자는 상상력이 풍부하고 재미있지만, 정확하지 않고 배려심이 부족한 직업이라고 생각하고 있었다. 수학자는 다른 직업에 비해서 영리하다고 생각하였으며, 공학자는 부지런한 직업이라고 생각하고 있었다. 넷째, 흥미와 진로 선택의 상관관계를 분석한 결과 과학과 수학 및 기술/공학은 서로 상관관계가 높게 나타났다. 이러한 결과를 토대로 영재 교육에서 융합형 영재 교육의 강화 및 체계적인 진로 교육 확립의 필요성과 수학 및 기술/공학의 상관관계에 대한 체계적인 연구의 필요성을 제언하였다.

In this paper, we examine the brief history of the ring of four almonds regarding Mesopotamian mathematics, and present reasons why the Omar Khayyam's triangle, a special right triangle in a ring of four almonds, was essential for artisans due to its unique pattern. We presume that the ring of four almonds originated from a point symmetry figure given two concentric squares used in the proto-Sumerian Jemdet Nasr period (approximately 3000 B.C.) and a square halfway between two given concentric squares used during the time of the Old Akkadian period (2340-2200 B.C.) and the Old Babylonian age (2000-1600 B.C.). Artisans tried to create a new intricate pattern as almonds and 6-pointed stars by subdividing right triangles in the pattern of the popular altered Old Akkadian square band at the time. Therefore, artisans needed the Omar Khayyam's triangle, whose hypotenuse equals the sum of the short side and the perpendicular to the hypotenuse. We presume that artisans asked mathematicians how to construct the Omar Khayyam's triangle at a meeting between artisans and mathematicians in Isfahan. The construction of Omar Khayyam's triangle requires solving an irreducible cubic polynomial. Omar Khayyam was the first to classify equations of integer polynomials of degree up to three and then proceeded to solve all types of cubic equations by means of intersections of conic sections. Omar Khayyam's triangle gave practical meaning to the type of cubic equation $x^3+bx=cx^2+a$. The work of Omar Khayyam was completed by Descartes in the 17th century.

조선 말기부터 대한제국, 일제 강점기를 지나면서 근대수학을 도입하는 과정과 해방 직후 국내 수학계의 주변 환경을 소개하며, 이를 통하여 근대수학을 도입하는 과정에서 겪었던 우리의 노력과 장애물들을 회고해보고 이를 현 시점에서 반추해보고자 한다.

The subject matter of this survey has to do with holomorphic maps from a compact Riemann surface to projective space, which are also called algebrac curves; the theory we survey lies at the crossroads of function theory, projective geometry, and commutative algebra (although we should mention that the present survey de-emphasizes the algebraic aspect). Algebraic curves have been vigorously and continuously investigated since the time of Riemann. The reasons for the preoccupation with algebraic curves amongst mathematicians perhaps have to do with-other than the usual usual reason, namely, the herd mentality prompting us to follow the leads of a few great pioneering methematicians in the field-the fact that algebraic curves possess a certain simple unity together with a rich and complex structure. From a differential-topological standpoint algebraic curves are quite simple as they are neatly parameterized by a single discrete invariant, the genus. Even the possible complex structures of a fixed genus curve afford a fairly complete description. Yet there are a multitude of diverse perspectives (algebraic, function theoretic, and geometric) often coalescing to yield a spectacular result.

This study is to compared with 7-ga mathematics textbooks of 13 types in the middle school by 7-th curriculum. A synopsis of the Analysis and comparison about the contents of these textbooks is as follows. -The order of contents almost is same about the title and contents in 13 types of textbooks. -It is very important that the definition of terminology should be simple and correct. I investigated the terminology in thirteen textbooks of material at 7-th curriculum. -Most of their textbooks present the motivation of learning mathematics with resource of life such as a story of mathematics and famous mathematicians. -The chapter about numbers and operations has the biggest volume of all. -The evaluation of lessons presents at the each end of chapters with many problems as levels.

In 1968k Cameron and Storvick introduced the analytic and the sequential operator-valued function space integral [2]. Since then, the theo교 of the analytic operator-valued function space integral has been investigated by many mathematicians - Cameron, Storvick, Johnson, Skoug, Lapidus, Chang and author etc. But there are not that many papers related to the theory of the sequential operator-valued function space integral. In this paper, we establish the existence of the sequential operator-valued function space integral as an operator from $L_p$ to $L_p'(1 and investigated the integral equation related to this integral.

In 1992, the author introduced the definition and the properties of Wiener measure over paths in Wiener space and this measure was investigated extensively by some mathematicians. In 2002, the author and Dr. Im presented an article for analogue of Wiener measure and its applications which is the generalized theory of Wiener measure theory. In this note, we will derive the analogue of Wiener measure over paths in Wiener space and establish two integration formulae, one is similar to the Wiener integration formula and another is similar to simple formula for conditional Wiener integral. Furthermore, we will give some examples for our formulae.
