It features that research on hun-min-jeong-eum訓民正音had been made mostly led by Soron少論Faction in the latter half of Choson Dynasty. That is almost triggered by academic background whose research mostly focused upon Hwang-geuk-gyung-seh-suh皇極經世 書. In addition to this, they had a unique recognition of Choson's Chinese character sound. That is, there remained old and ideal sound of ancient times. within Choson's Chinese character sound, and some of them asserted that Choson's Chinese character sound should be made as righteous sound(jeong-eum, 正音) instead of Chinese sound that had bee contaminated by a barbarian's sound. The recognition to such Choson's Chinese character sound shows well their Sino-centralism which tried to internalize that of ancient times that they had through Gija(箕子). On top of such recognition, Shao yong(邵雍)'s Hwang-geuk-gyung-seh-suh(皇極經世書) added to the understanding of phonology･phonetics to them, they started to happen to pay interest to hun-min-jeong-eum as a tool to completely restore the past righteous sound(jeong-eum). Therefore, what is known as research on the past hun-min-jeong-eum, that is to say, means, strictly speaking, a way to restore old sound, righteous sound(jeong-eum) through hun-min-jeong-eum rather than a research itself on hun-min-jeong-eum. This can be inferred from Hwang-geuk-gyung-seh-suh which they deemed as a model. Soron's phonology research, I believe, was strongly to reveal Sino-centralism consciousness of ancient times in its preception of a goal, through hun-min-jeong-eum as a means. In this process, they could make a deeper research on functions of hun-min-jeong-eum, and they, further, advanced into guessing possibility of turning sound of hun-min-jeong-eum into letters.
