The study on the heat release and the engine performance of CI engine is experimentally performed with variation of compression ratio and inlet pressure. In this experiment, compression ratio in cylinder is decreased and inlet pressure is increased. The results of this study are as follow: the thermal efficiency increases and the maximum combustion pressure decreases as compression ratio declines and inlet pressure rises. For the case of the same mean effective pressure, specific fuel consumption and smoke become to be low. According to the results, the advantages are achieved for the noise, vibration, performance and smoke.

The genetic relatedness among the Korean Drosophila quinaria species group, including D. nigromaculata, D. unispina, D. brachynephrose, and D. angularis, has been examined by using horizontal starch gel electrophoresis. The results showed that none of the ten isozyme patterns examined for these four species was identical. The average genetic similarity among the four species was found to be 0.440. The similarity among three species. D. unispina, D. brachynephrose, and D. angularis was 0.466. The relatedness was found to be closest between D. nigromaculata and D. unispina, showing 0.640. D. nigromaculata and D. angularis showed relatedness of 0.258. The results suggested that these four species appear to be genetically related at the level of sibling species. The percent polymorphism in D. brachynephrose was found to be 76.9%, showing significant genetic variations.

Influence of Hyoscine-N-butylbromide on visualiation of the upper urivary tract by intraveous pyelograbhy Jae Choon Cho, Kee Soo Kim. Department of Urology, Catholic Medical College Seoul, Korea The intravenous pyelography is a valuable diagnostic procedure in urological studies. There are four kinds of methods in the visualization of the upper urinary tract: Retrograde pyelography, minute sequence pyelography, antegrade pyelography and intravenous pyelography. Each procedure has its own advantages depending i on the purpose required. In the intravenous pyelography every effort should be made to protect expelling of the radiopaque medium from the renal pelvis into the bladder. The compression exerted on the abdomen around the lower ureters and the Trendelenburg gposition of the table are the choice of methods for this intravebut those are uncomfortable prodecures for the patient even though they are as a routine used in the purpose nous pyelography. Urine and other contents in the renal pelvis and ureters are drained into the bladder by ureteral peristalsis which is controled by parasympathetic nerves. So far no parasympatholytic agents such as atropine, scopolamine and other similar drugs were found to inhibit the ureteral peristalsis. C.H. Boehringer Sohn have synthesized Hyoscine-N-butylbromide from scopolamine in their laboratory. Helmut Wick in 1951 reported by experiments Hyoscine-N-butylbromide to be a parasympathetic ganglion blocking agent which inhibits spasms of the smooth muscles and peristalsis in the `gast-ro-intestinal tract, bronchus, kindney, ureters, bladder and uterus. The purpose of this study is to observe the influence of Hyoscine-N-butylbromide on ureteral spasms and the size of the kidney by intravenous pyelography. The authors choose 30 patients whose urography showed a spastic ureteral narrowing and a kinking of the ureter. Each patient was given 2 ml of Hyoscine-N-butylbromide intramusculary 30 minutes before intravenous pyelography was taken without compression on the lower abdomen and without changing of the patient's position. The results obtained were as follows: 1. Spastic ureteral narrowing due to increased ureteral peristalsis subsided by injection of Hyoscine-N-butylbromide on I.V.P. 2. Hyoscine-N-butylbromide was helpful to visusalize the upper urinary tract in the I.V.P. in spine positionl without compression of the lower abdomen and/or by tilting the table. 3. The size of the kidney was enlarged by 1.0 cmX 1.5 cm and caliber of the ureter was also enlarged by 3cm following an injection of Hyoscine-N-butylbromide for I.V.P.

Helicobacter pylori is a Gram-negative bacterium which causes chronic gastritis and is associated with gastric ulcer, duodenal ulcer and gastric carcinoma. In the process of screening of antibacterial activities against H. pylori from soil microorgani는, fungus No. 60686 was isolated. After fementaion of No. 60686, the antibacterial compound was isolated, purified and followed by extraction of mycelium with orgainic solvents, acetone and ethyl acetate, through silica gel chromatography, LH-20 gel chromatography and HPLC. As a result of the structural analyses of the compound by IR, ^1H- and ^13C-NMR, FAB/Mass spectrophotomer, the compound having the antimicrobial activity was idenfitied as chaetoglobosin A (C_32H_36N_2O_5), a cytochalasan derivative. The antimicrobial activity of chaetoglobosin A was tested against Gram-positive and negative bacteria by paper disk method. Among the test strains of 9 Gram-positive bacteria and 18 Gram-negative bacteria containing 4 H. pylori strains, the growth of 4 H. pylori strains and 3 S. aureus strains (SG 511, 285 and 503) was only inhibited by chaetoglobosin A. Also it was shown that its growth inhibition against H. pylori strains was stronger than that against S. aureus strains at the treatment of the same concentration. Therefore it was concluded that chaetoglobosin A has a specific growth inhibition against H. pylori of the tested bacteria.

In public school, they felt relatively more bored, and on the other hand, they were relatively more anxious in proprietary school. 2. Korean high school students felt more positive emotions when they were in public school than in proprietary school. 3. Korean high school students were more involved into study when they were in public school than in proprietary school. 4. Korean high school students were more satisfied when they were in public school than in proprietary school.

古代 英雄小說 變貌의 一樣相硏究 : Centering around antagonists' power development and transfiguration in the image of a hero 主人公의 能力 培養과 英雄像의 變貌를 中心으로

金重烈,安圻洙 群山大學校 1994 論文集 Vol.21 No.-

The purpose of this paper is to examine the ways of developing heroic power possessed by protagonists in old heroic novels and to investigate how they take advantage of this as a means of self-realization, and to consider what changes the figurative methods show at later stages. Especially, although power development styles were phenomena which appeared throughout old novels, different meanings were represented with different methods. It is noted that in heroic novels whose protagonists are heroes, such power development enabled them to live a successful, ascending life. Since the writers of heroic novels and ther years in which they were written are unknown, we can only make a conjecture in considering their writers and their consciousness of the era. However, it is not very difficult to examine the literary traditions at that time since the heroic novels were produced in the spatio-temporalcontext of the Yi Dynasty. It is conjectured that heroic novels have originated from lyrics in myths. This results from focusing on the heroic lives of protagonits. Consequently, it seems that the personalities of heroes in heroic novels have been changed through this process. First, let us consider the innate supernatural power of a mythological protagonist and the image of a hero. In the myth of Jumong, the protagonist appears as having the image of a hero who overcomes the conflict with the world. The protagonist Jumong's birth to diviner beings reveals that he is a descendant of a god. Her is born with innate, extraordinary power, and confronts the world for himself alone. On the other hand, in heroic novels, the image of a hero is shown through his mother's dream she has when she gets pregnant. Different from divine characters in a myth, the protagonist's divinity is revealed through his mother's dream in which her baby becomes a divine character in the future. There are some heroic novels in which antagonits perform passive power assisted by a savior. Saviors do not exist in myths or early heroic novels, but they always do appear in alte heroic novels, and they recognize the protagonist's greatness and raise heroic power. So we can see the passive image of a hero in late heroic novels. In addition to saviors' raising of protagonits's power, wupplementary tools were given to the protagonist. This made it possible to figurate an ordinary heroic character, who is more like a human being. Thus, we can see that a hero's power transfigurates from having supernatural power to absolute power in early heroic novels, and to ordinary abilities in late heroic novels.
