Conceptions about functions of large & small intestine[LI & SI] were focused on the vermiculation in "Somun(素問) Yeongranbijeonron(靈蘭秘典論)". However, functions of large & small intestine includes more. In Oriental Medicine, there are sentences in "Hwangjenaegyeong(黃帝內經)" "LI manages Fluid [津] and SI manages Humor[液]" It means that LI & SI have an each role in digestion besides vermiculation. In that reason, we try to find out the meaning of the functions of LI and SI in digestion through bibliographic review. As a result, LI and SI have a digestic function by Separating the Clear which includes Fluids and Humor and the Turbid which is relatively useless to the Clear.

This study investigates the phonetic meaning of clarity and turbidity(淸濁) that has been used in psychoacoustics, musicology, and linguistics in both the East and the West. With a view to clarifying the phonetic meaning of clarity and turbidity, this study conducts three perception tests. First, 34 subjects were asked to take one of Clear and Turbid by forced choice for 5 pure and complex tones, respectively, ranging from A2 to A6 differing by octave. Second, they were asked to select between the two choices for 25 pure and complex tones, respectively, ranging from A2 to A4 differing by semitone. Third, they were asked to opt for one of the two choices for 8 different vowels of different formant and fundamental frequencies. Results showed that there is a certain range of tone which is perceived as clear, that clarity level increases as fundamental frequency increases, and that pure tones have a higher level of clarity than complex ones, fundamental frequency being equal. Results also showed that vocal tract resonance enhances clarity level on the whole, and that lower vowels have a higher level of clarity than higher ones. This study is significant in that it demonstrates that clarity level is proportional to fundamental frequency and the first formant frequency, all else being equal.
