The stream morphological characteristics of a watershed play a significant role in the analysis of rainfall-runoff relations in a river basin and a quantitative description of these characteristics is essential for determining the appropriate values of physical parameters of a watershed which usually are input data for rainfall-runoff simulation models. In this study the stream morphological characteristics of the Gab River basin, which is one of the three major tributaries of Geum River, was determined quantitatively by the Horton-Strahler's method. The result showed that the Gab River System was developed very closely to the patterns generally described by the laws of Horton. The basic relations concerning the morphological characteristics deriveed in this study are the relations of stream length, and average stream slope, the stream length-drainage area relation, relative height-relative drainage area relation, and the relation between the proportional stream order and drainage area. No correlation analysis was possible between the morphological parameters and the streamflow due to non-existence of the stage gauging stations on the Gab River System.

The following results were obtained. 1.In the constitution which had discriminated by survey, in the value of Prostaglandin E2 in bood of ammong four constitutiens didn,t showed significant differance. 2.In the constitution which had discriminated by study on the morphological diagrammings, in the value of Prostaglandin E2 in bood of ammong four constitutiens didn,t showed significant differance. 3.In the constitution which had discriminated by the result of patient of hospital on a dosage of constitutial prescription, the value of Prostaglandin E2 in blood of among four constitutions didn,nt showed signicant differance. 4.In the constitution which had discriminated by colligated three methods(survey, morphological diagrammings,the result of patient of hospital on a dosage of constitutial prescription), the value of Prostaglandin E2 in blood of ammong four constituion didn,t showed significant differnce. 5.In the constitution which had discriminated by survey, a test of significance between the value of Prostaglandin E2 in blood of each constitution and the value of Prostaglandin E2 in blood of the others was conducted. Only the value of Prostaglandin E2 in blood between in the TAE-EUM-IN(太陰人) and the others of female showed significant differance. 6.In the constitution which had discriminated by study on the morphological diagrammings,a test of significance between the value of Prostaglandin E2 in blood of each constitution and the value of Prostaglandin E2 in blood of the others was conducted. Only the value of Prostaglandin E2 in blood between in the SO-EUM-IN(少陰人) and the others of male showed significant differance. 7.In the constitution whichhad discriminated by the result of patient of hospital on a dosage of constitutial prescription,a test of significance between the value of Prostaglandin E2 in blood of each constitution and the value of Prostaglandin E2 in blood of the others was conducted. Only the value of Prostaglandin E2 in blood between in the TAE-EUM-IN(太陰人) and the others of male showed significant differance. 8.In the constitution which had discriminated was the colligated three methods(survey,morphological diagrammings,the result of patient of hospital on a dosage of constitutial prescription),a test of significance between the value of Prostaglandin E2 in blood of each constitution and the value of Prostaglandin E2 in blood of the others didn,t showed significant differnce. In this connected study is inadequete at present. But if the study is done persistently,the analysis of various ingredient in the body enables objectification in differentiation of four types of physical constitution as the supplemental method.

Objectives : In order to distinguish morphological characteristics of trunk bark and root bark of Ulmus davidiana var. japonica (Rehder) Nakai and the trunk bark and root bark of Hemiptelea davidii Planchon were sampled and compared in terms of their external and internal features with flour states according to their medical use, through microscopic examination. Methods : The slice of the tested material made by paraffin section technique was colored with Safranine Malachite Green contrast methods, and the flour of it was mounted by the liquid made by the same ratio of each of glycerin, acetic acid, and water, and then observed and photographed by olymphus-BHT. Results : 1. Internal Features 1) A large parenchymatous cell was observed in the phloem of the slice of both trunk bark and root bark of Ulmi Cortex, However, both of the trunk bark and root bark of Hemipteleae Cortex did not have parenchymatous cell in the phloem; instead, stone cells including much square crystal of calcium oxalate were distributed around fiber bundle, and the parenchymatous cell included much druse crystal of calcium oxalate. 2) In both the Ulmi Cortex and Hemipteleae Cortex, rhytidome was observed in trunk bark, but not in root bark, but in the parenchymatous cell of the root bark of the Ulmi Cortex contained starch grain. 2. Flour States 1) In the flour of root bark of the Ulmi Cortex, a large parenchymatous cell was observed. However, in the flour of trunk bark and root bark of Hemipteleae Cortex, no parenchymatous eel was found; instead, stone cell including square crystal of calcium oxalate and druse crystal of calcium oxalate were observed. 2) There was no remarkable difference between the trunk bark and root bark of Hemipteleae Cortex. However, starch grain was contained in the parenchymatous cell of the root bark of Ulmi Cortex but not in the trunk bark of it. Conclusions : There were some morphological differences in external, internal, and flour parts of Ulmi Cortex and Hemipteleae Cortex. In particular, there was a morphological difference in flour states between the trunk bark and root bark of Ulmi Cortex, it is possible to use microscope to distinguish their flour states.

To clarify the key characteristics of Korean brown frogs (R. dybowskii, R. huanrenesis and R. amurensis coreana), this study employed a morphological and morphometrical comparisons among brown frogs found in Korea and Japanese endemic species, R. tsushimensis. As a result, it was considered that the key characteristics were the shape of the finger and toe tips, the markings of the lower jaw, the presence or absence of an upper lip line, the development of toe webbing, and the shape of the vomerine teeth series by morphological comparisons of brown frogs. Also, there were significant differences in tympanum diameters and foot lengths of the four species of brown frogs. Therefore, a comparison between morphological and morphometric characters is an effective way to clarify the identification of brown frogs.
