양의장,김규환,함형일,강영흥 한국항행학회 2003 韓國航行學會論文誌 Vol.7 No.1

본 논문에서는 성층권 통신 시스템 (HAPS : High Altitude Platform System)과 NGSO (Non-Geostationary Orbit) 시스템간 간섭 영향을 두 가지의 경우로 나누어서 분석한다. 한가지는 HAPS 시스템이NGSO 시스템에 미치는 간섭이며, 다른 한가지는 NGSO위성이 HAPS시스템에 미치는 간섭 영향이다. 그 결과NGSO 이동국이 받는 간섭은 NGSO위성 위치가 95?일 때 가장 높게 나타났으며, 이때 HAPS와 NGSO모두에 의한 간섭은 사용자 수가 20명 이상부터 간섭 기준을 초과함을 알 수 있었다. 그리고 HAPS 이동국이 받는 간섭의 경우에는 NGSO 위성 양각이 87?일 때 가장 높은 간섭이 나타났으며, 이 때 NGSO와 HAPS 모두에 의한 간섭은 사용자 수가 10명 이상부터 간섭 기준을 초과함을 알 수 있었다. 또한 64?일 때 가장 낮은 간섭이 나타났으며, 이때 NGSO와 HAPS 의 사용자 수가 같을 경우에는 190명에서부터 간섭을 초과함을 알 수 있었다. In this paper, we analyze the interference effects between NGSO(Non-Geostationary Orbit) and HAPS(High Altitude Platform System) by dividing into two cases. The one is interference effects of HAPS into NGSO, the another is the interference effectes of NGSO into HAPS. At the result, we can know the interference effect into NGSO mobile station is the highest when position of NGSO is 95%. In this case, we can also know the interference effects from both HAPS and NGSO exceed interference criteria when the number of users are more than 20. And, in the case of the interference effect into HAPS mobile station, we can know it is the highest when elevation angle of NGSO is 87°, and the interference effects from both NGSO and HAPS exceed interference criteria when the number of users is more then 10. Moreover, the interference effect is the minimum, when elevation angle of NGSO is 64°, at this time, in case that the number of users of NGSO equal to the number of user of HAPS, the interference effects exceed interference criteria when the number of users is 190.

Thomas Wolfe의 You Can't Go Home Again에 나타난 美國人의 性格

梁永洙 제주대학교 1983 논문집 Vol.16 No.1

T.Wolfe tried to embody American spirit in his last novel, You Can't Go Home Again, and George Webber, the hero of it, was the other self of T.Wolfe. G.Webber is showing many of American characteristics. As American people were so brave as to give up the time-honored European establishinents, so G.Webber had the courage to sever himself from his homeland and the people there by disclosing the dehumanizing phenomena arising from the economic boom of his longcherished homeland. Both made efforts to outgrow their past selves, hoping to enjoy richer life in the future. G.Webber's self-enlarging character gets rooted in the attitude that all things on the earth are destined to change and men can adapt themselves to the changes only by incessant renovations of themselves. And so, Webber could quit his beloved Esther with equanimity, now that he came to realize that she belonged to the high circles which tend to overlook the painful reality of human being and society. His fondness for traveling also has its origin in his self-renewing endeavour, and his experiences in Germany under the rule of the Nazis brought to him the deep-rooted cruelty in the human mind. Consequently, he resolved to stop his friendship with his editor, Foxhall, because the philosophical resignation of the latter could not be in harmony with his determined progressiveness. He believed in historical progress, while the hard-minded fatalist thought that human nature and inclination to crime cannot be changed in spite of everlasting reformation. This separation also shows that Webber is willing to renounce his familiar possessions in hoping for richer and better ones.

G.Eliot의 生涯와 作品에 나타난 共感的 휴머니즘의 道德觀

梁永洙 제주대학교 1984 논문집 Vol.17 No.1

G. Eliot can be said to be a humanitarian novelist, and her moralism of humanity is characterized by the emphasis on sympathetic ties with other people. Her thought of morality is far off from the Christian code of morality. She did not believe in the Christianity's claim to be the beginning of human morality, and she maintained that the origin of men's morality is nothing but humanity itself. But she didn't disparage the Christian, or religious, attitude on moral behavior and she was quite on guard against the radical uheaval in thoughts as well as in institutions. On the contrary, she paid the fullest respect to the people's endeavour to regulate and chasten their behaviors by means of various forms of religion in the human history. The keypoint in her revolutionary view of morality is not in that she disagreed with the Christian creeds, but in that the moral order was considered not to be dependent for its origins upon the Christianity. In G. Eliot, the chief agent of morality is human feeling-the sympathetic feeling which comes from men's experiences of suffering and social interaction. Maggie, the heroine of The Mill on the Floss, suffers from the tragical flaws which, not without the lofty ideals, put her into endless conflicts with surrounding characters. But such sufferings as Maggie is experiencing are the very basis on which the true sympathetic morality is based. After her long discord with Tom, her brother, she comes to understand and tolerate his bigotry as against her own egotism. Maggie's own isolated experience in the past enables her to be uncommonly tender-minded to Philip's crippled body and his alienated mind. Faithful to her past love with Philip and to her strong community-consciousness towards her cousin Lucy, Maggie has to refrain from pleasure-seeking love affairs with Stephen. The last scene of this novel, in which Maggie and Tom are dying in an embrace never to be parted, symbolizes G. Eliot's moralism of sympathetic humanity after Ieng suffering. But, the fact that their disagreements are settled only by means of death can be interpreted to signify that her optimistic view on human morality of sympathy is obviously limited.

The Great Gatsby의 悲劇的 構造

梁永洙 제주대학교 1984 논문집 Vol.18 No.1

Critics of F.S. Fitzgerald tend to agree that The Great Gatsby is a literary production of the Jazz Age, i.e. America's earlier nineteen-twenties, or the artistic representation of a depraved deviant of the American dream. This essay is, however, trying to view this novel as an embodiment of the universal kind of human illusion and disillusion,admitting that this novel was originally a faithful expression of the spirit of an age. The essence of the idealistic vision whose tragedy Gatsby is enacting is that it is based on a past and a future that are not substantial or influential, and helpless in the present that is. In Gatsby's tragedy are involved many characters who are standing out in sharp contrast to him. Nick, the narrator of this novel, is realistic and moralistic, and so he tries to persuade Gatsby to give up his long cherished one-sided love to Daisy, but his scrupulous attitude provides no help in preventing Gatsby's dectruction. Daisy is the object of Gatsby's tenacious love, but she is quite devoid of the capacity of loving, or being loved by, somebody else, and so her response to his whole-hearted affection is stolid and inhumane. She and her husband Tom lead Gatsby to be shot by Wilson, even though they know Daisy herself is the actual culprit of the killing of Myrtle who is Wilson's wife and Tom's mistress as well. Gatsby's attachment to his past dream is so strong as to deprive him of reasonable judgement of his present situation.

Cr(VI) 헤테로고리 착물에 의한 알코올류의 산화반응에 대한 메카니즘 연구

양정성,박영조 慶南大學校 附設 基礎科學硏究所 1994 硏究論文集 Vol.6 No.-

In N,N-Dimethylformamide(DMF) solvent, Cr(VI)heterocyclic Complex oxidized benzyl alcohol and its derivatives(p-CH₃, m-Br, m-NO₂) smoothly in the presence of hydrochloric acid(HCl). The reaction was dependent on alcohol, Cr(VI)heterocyclic complex and acid concentration. Electron-donating substituents accelerated the reaction, whereas electron-withdrawing groups retarded the reaction. The Hammett reaction constant<p> was -0.69 at 308 K. The observed experimental data have been ratiolized. The hydride ion transfer causes the prior formation of a chromate ester in the rata-determining step.

The ultrastructural development of fetal liver cells according to the activity of hepatic erythropoiesis was studied with 15 human fetal livers from 7 to 34 weeks of gestation. 1) The 1st state(7-8 weeks of gestation) : The nucleus of hepatocyte was oval with granular euchromatin evenly dispersed throughout the interior and prominent nucleoli. The hepatocytes often exhibited many mitochondria and short dilated rERs but no sERs and glycogen deposit. Two types of reticulum cells with intracellular organells developed with close relation with erythropoietic cells. The nucleus of the 1st type was similar with that of hepatocyte and the cytoplasm was full of well-developed multiayered rERs and numerous mitochondria. The nucleus of the 2nd type was irregular and has high electron-dense nucleoplasm. and the cytoplasm was packed with more developed multiayered rERs and oval mitochondria. 2) The 2nd state(9-22 weeks of gestation) : Most of hepatocytes differentiated well and exhibited numerous mitochondria and free ribosome, 5 to 6 layered rER, glycogen deposit, and there were sppearance of sER and hemosiderin in the cytoplasm. With age, the 2nd type reticulum cell became the majority and had more glycogen deposit and less rER. The space of Disse was well-developed but the sinusoidal wall still immature. 3) The 3rd state(23-34 weeks of gestation) : The majority of hepatocytes were mature cells. Reticulum cells, greatly decreasing with age, exhibited increasing lipid storage and decrease of mitochondria and rER. In summary, the maturation of hepatocyte and activity of reticulum cell may influence the hepatic erythropoiesis.

A prospective research of 1,573 patients who visited emergency room was completed by the emergency physician of Wonju College of Medicine of Yonsei University, and Youngdong Hospital. This prospective study demonstrate the problems of prehospital emergency care and transfer system of the emergency patient. Among 1,573 patients, 86.9% were admitted to the Emergency room by the non-emergency vehicle such as taxi and bus, and only 13.1% was admitted via ambulance. At the situation of emergency, the most of patients and patient`s families could not call for the help to emergency telemetry center because only 3.1% among total patients knew the emergency call number(Tel. No: 129). Because the emergency delivery system between emergency centers from Level. Ⅰ, Ⅱ to Level Ⅲ was not established yet, only 492 patients(31.3%) were transferred from Level Ⅰ, Ⅱ emergency room to our emergency room to our emergency center but 1081 patients(68.7%) were admitted directly to Level Ⅲ emergency center from emergency fields. Among 1,081 patients who visited Level Ⅲ emergency center directly, only 240 patients(23%) were admitted for further treatment, but in transferred cases(492 patients), 271 patients(55%) were admitted. Especially in the injured patients, severely injured patients(ISS 16) occupied only 6% among 441 patients who visited directly, but it occupied 21% among 150patients who were transferrd from local community hospital. This result means that many non-urgent patients visited Level Ⅲ emergency centers without the previous visiting of Level ⅠⅡ emergency room. This study reveals that EMSS(Emergency Medical Services System) including the telemetry systems must be organized in short-time to reduce the mortality and morbidity of emergency patients. First, the educations about the emergency call system and First Aids to the people must be stsryed initially through the school and mass-media such as television and radio network. Second, emergency delivery system between Level Ⅰ,Ⅱ,Ⅲ emergency center must be organized for the effective and rapid transportaion of acute ill patients.

A new instantaneous flowmeter for water hydraulic by means of cylindrical chokes is developed. In this method the instantaneous flowrate through chokes is predicted in real time from measurement of pressure difference on both sides of cylindrical choke. The experimental study for the flowrate of pulsating flow in a pipe is carried out to measure differential pressure drop by using a strain gauge pressure transducer with data acquisition and processing system. A pulsating flow is verified by visualization method. In the present study, the flow charcteristic variables of laminar pulsating flow are investigated analytically and experimentally in a circular pipe. Characteristics parameters of ratio of inertia term and pressure term(Φ_t.1) and ratio of viscous term and pressure term (Φ_z.1) are introduced to describe the flow pattern of laminar pulsating flow.
