邵康節 數學이 15-16세기 조선 音韻學에 끼친 영향 -『訓民正音』과 徐敬德의 『聲音解』를 중심으로-

Abstract

This paper is an analysis of The Influence of Shaoyong(邵雍)'s mathematics on the Hunminjeongum and Seok Kyung Deok's shēngyīnjiě. It is a well-known fact that Hunminjeongum is influenced by Shaoyong. Seok Kyung-duk is a specialist in Shaoyong(邵雍)'s mathematicsof Joseon Dynasty and his "shēngyīnjiě" is the first commentary of the lecture. Shaoyong(邵雍)'s shēngyīn was composed of phonology and mathematics, and he combined both of them appropriately to have a great influence on Chinese and Joseon's xiang shu and phonology. At the core of the Shaoyong(邵雍)'s mathematics, I have learned that the four senses theory and the 'gail' method[the doublet method:加一倍法], the three syllables, the poles [10, 12], the body number and the use number. Among these, the mathematical part that influenced the creation of the Hunminjeongum is the 'gail' method. It is the process of the generation of the I-ching by the rule of number which blows twice as like '1-2-4-8'. If we calculate the case of 11 the second voices, it can be expressed as '1 [Heaven] -2 [Ground, People] -4 [First letter] -4 [Second letter]'. That is the 'gail' method[the doublet method:加一倍法], as '1-2-4'. Seo Kyung-duk's "shēngyīnjiě" shows that his understanding of the Shaoyong(邵雍)' mathematics is not much different from other scholars. Among them, the emphasis is on the number of '16', which is the perfect combination of Heaven's four image and Earth's four image. However, the part to be evaluated by Seok Kyung Deok is that he learned the Shaoyong(邵雍)' mathematics and provided the basis for developing the phonology of Joseon. In other words, it is a word that can not be filled in the Shaoyong's shēngyīn chang he tu(邵雍의 聲音唱和圖) but it is suitable for '○' which has no letter. Seo Kyung-duk's insights became the fountain of the development of mathematical phonology of Joseon in the late period, including Choi, Shin, Hwang, and so on.
