중세 韻書에 나타난 唇內撥音字의 漢字音 연구

In this article, I studied on system of Sino Japanese of Final m in Muromachi period focusing on “Bunmeiban Syubuninryaku” and “Ryakuin” “Keichouban Syubuninryaku”. The result of analysing each “Setsu” consistency by comparing, The “To'on” at “Bunmeiban Syubuninryaku” and “Keichouban Syubuninryaku” was common, but “To'on” at “Ryakuin” was slightly different from general “To'on” of Rhyme Texts. “Sinsetsu” were almost coincided and “Kansetsu” was not coincided. As a result, there is a strong similarity between the “To'on” of several “Syubuninryaku” and they are in extremely close proximity to each other in system.
