  • 본고에서는 2013년 대한민국 과학기술 명예의 전당에 조선시대 수학자 최석정(崔錫鼎 1646~1715) 선현이 헌정된 것을 기념하여 그의 저서 구수략(九數略)에 기록된 '직교라틴방진'이 조합수학(Combinatorial Mathematics)의 효시로 일컫는 오일러(Leonhard Euler, 1707~1783)의 '직교라틴방진' 보다 최소 61년 앞섰다는 사실이 국제적으로 인정받게 된 경위를 소개하고 최석정의 9차 직교라틴방진의 특성을 살펴본다.

  • This study shows how to use effectively construction and solution of the quadratic equation developed by mathematicians such as Gyung Sun-jing, Hong Jung-ha, Hong Dae-yong, Lee Sang-hyuk, and Nam Byung-gil through mathematics history of Chosun Dynasty. Mathematics history of Chosun Dynasty can be used in order to enhance comprehension and increase interest in an introduction to the quadratic equation. It also can be used to help motivate middle school students to solve the quadratic equation with much interest during the development phase, and develope conceptual thinking and reflective thinking in the practical phase.

  • The magic square is one of the number arrangements and the sums of each row, column, and diagonal are all equal. The meaning of "方" is "Square". If we don't consider the condition of 'square' then is it possible any number arrangement? There are many special number arrangements such as "magic five number circle(緊五圖)", "magic six number circle(聚六圖)", "magic eight number circle(聚八圖)", "magic nine number circle(攢九圖)", "magic eight camp circle(八陣圖)", "magic nine camp circle(連環圖)" in the ancient Chinese mathematics books such as "楊輝算法", "算法統宗". Also, there is a very special and beautiful number arrangement Jisuguimoondo(地數龜文圖) in the mathematics book "Goosuryak(九數略)" written by Choi suk jung(崔錫鼎) in the Joseon Dynasty. In this study, we introduce a various number arrangements and their properties.
