Chung Ji Yong is a well-known poet in the Japanese Occupation Period firstly as a lyrical and traditional poet as a member of the literary journal Simunhak(Poetry Literature) along with Park Yong Chul and Kim Young Rang and later as a prominent modernist poet in the late years of the Period. He is always highly estimated as a poet of pictorial images and lyricism, but his ardor for translations, especially Walt Whitman has been neglected so far. Before him, Ju Yohan, Yi Kwang Soo, Yi Un Sang, Kim Hyung Won and many other poets and critics had been interested in Whitman's democratic ideas and his poems. Chung Ji Young also translated Whitman's three poems in the hard days of 1930s. After the Imperial Japan surrendered to the Allied forces on 15 August 1945, ending 35 years of Japanese occupation, Korea was under the American forces and Russian troops. In this critical days of Korean's debating only one korea or separated Koreas, strangely enough, Chung ji Yong fully immersed in translating Whitman's poems only for four years as an English literature professor just before being abducted by North Korean Army, while almost discarding his own poetic ability and sense of duty as a leading poet in the literary circle with only just a few exceptions. Why did Chung Ji Yong focused on the translation of Whitman's poems in this important period as a poet and intellectual in the newly independent country? He may want to warn people too much ideological conflicts or at least express his frustration through translating Whitman's poems. Until now, academic endeavors on Chung Ji Yong's poems and life are focused on his lyrical and modernistic works of the Japanese Occupation Period and naturally little interested in the days of Independence period and his true motivations on translating Whitman's poems. As a proposal, this short article can be a minor trigger for the sincere efforts of Chung Ji Yong's last days.

This study examined the effect of Gamma-Amino butyric acid (GABA) and selective GABA receptor related drugs on the electrically stimulated relaxation in the lower esophageal sphincter muscle (LES) of a cat. Tetrodotoxin $(10^{-6}\;M)$ suppressed the electrically stimulated (0.5-5 Hz) relaxation of the LES. However, guanethidine $(10^{-6}\;M)$ and atropine $(10^{-6}\;M)$ had no effect indicating that the relaxations were neurally mediated via the nonadrenergic and noncholinergic (NANC) pathways. NG-nitro-L-arginine methyl ester ($10^{-4}M$, L-NAME) also inhibited the relaxant response but did not completely abolish the electrically stimulated relaxation with 60% inhibition, which suggests the involvement of nitric oxide as an inhibitory transmitter. This study examined the role of GABA, an inhibitory neurotransmitter, on neurally mediated LES relaxation. GABA ($10^{-3}-10^{-5}M$, non selective receptor agonist), muscimol ($10^{-3}-10^{-5}M$, GABA-A agonist), and baclofen ($10^{-3}-10^{-5}M$, GABA-B agonist) had no significant effect on the electrically stimulated relaxation. Moreover, bicuculline ($10^{-5}M$, GABA-A antagonist) and phaclofen ($10^{-5}M$, GABA-B antagonist) had no inhibitory effect on the electrically stimulated relaxation. This suggests that GABA and the GABA receptor are not involved in the electrically stimulated NANC relaxation in the cat LES.

Taguchi's parameter design is to determine optimal settings of design parameters of a product or a process such that the characteristics of a product exhibit small variabilities around their target values. His analysis of the problem has focused only on a single characteristic or response, but the quality of most products is seldom defined by a characteristic, and is rather the composite of a great number of characteristics which are often interrelated and nearly always measured in a variety of units. The critical problem in dealing with multiple characteristics is how to compromise the conflicts among the selected levels of the design parameters for each individual characteristic. In this paper, the EXTOPSIS Model using SN ratio which can be optimized by univariate technique is proposed and a parameter design procedure to achieve the optimal compromise among several different response variables is developed. Two existing case studies are solved by the proposed method and the results are compared with ones by the sum of SN ratios, the expected weighted loss, and the desirability function.

Phytochemical constituents were isolated from bitter melon (the fruits of Momordica charantia) through open column chromatography. Their structures were identified as ${\beta}$-sitosterol (1), (23E)-$5{\beta}$,19-epoxycucurbita-6,23-diene-$3{\beta}$,25-diol (2), daucosterol (3), uracil (4), and allantoin (5) by interpretation of spectroscopic analysis including MS and $^1H$- & $^{13}C$-NMR. Among them, allantoin (5) was isolated from this plant for the first time.
