This study required a comprehensive review of the literature referring to tropical special crops. The following information was extracted. Production of cereals increased by 35% from 1970 to 81, and this increase hepled to alleviate the world food shortage. With reference to tropical oil crops, Africa and Asia grew 90% of the total world production of groundnuts. Africa producted 70% of the world's castor bean. The chief producing area of the other oil crops was East/South Asia. In the production of tropical starch crops, cassava is increasing rapidly, sago plam is spotlighted as a new tropical starch crop. The production of sugar cane as a sugar crop increased by 37% from 1970 to 81, and the demand continues to rise, it has good future prospect s. The production of coffee and tobacco, recreation crops has not increased very much over the past 10 years. However, the yield's per area increased markedly. The acreage of cotton, a tropical fiber crop, increased by a mere 2% but yields increased by 30% over the past 10 years. The principal tropical fruits are bananas and oranges and the present production of each crop exceeds 40,000,000 tons. The main producing area for bananas is East/South Asia and for oranges is South and North America. Ecological examination of 90 species of recreation, fiber, starch, sugar and oil crops showed that only 13 species of recreation, fiber, starch, sugar and oil crops showed that only 13 species are distributed in subtropical zones out of 47 arbor crop species and 33 species are distributed in subtropical zones out of 43 species of herb crops.

인터넷 캐쉬를 위한 멀티미디어 데이터의 재배치 정책

홍현옥,임은지,박성호 동의공업대학 2000 論文集 Vol.26 No.1

Through the dramatic growth of Internet, it becomes easy for people to access geographically distributed vast amounts of information. But, currently Internet is suffering from problems such as server overload, network congestion and client response time. In addition, currently the number of continuous media data such as audio and video is growing rapidly. In this paper, we propose SCU(Smallest Caching Utility) proxy caching scheme that stores a portion of continuous media stream or entire stream on the Internet. The proposed scheme reduces client latency and maximizes the amount of data served directly from cache without accessing the central server. By caching the initial fraction of stream data, service startup latency can be reduced. And, by varying the size of the fraction of stream to be cached according to variation of stream popularity, we can utilize the cache space efficiently and maximize the amounts of data served directly from cache. We use the caching utility formula of each stream for the measurement of cache replacement. The way to measure popularity of continuous media stream should be different from that of traditional data such as text and image. We propose the method of measuring popularity of stream using the amounts of data played by clients. We have performed simulations to evaluate our caching policy, Simulation results show that our caching policy outperforms other caching algorithms such as LRU, LFU and SIZE in aspects of BHR(byte hit ratio), initial latency and replacement overhead.

T.S.Eliot의 'Burnt Norton'에 나타난 宗敎的 意味

金炫玉 호남대학교 1999 호남대학교 학술논문집 Vol.7 No.2

Eliot is a poet of historical sense. The sense, acording to eliot, composes a simultaneous order, and is a mind changes, and that this change is develoment which abandons nothing en routh, signifying all the aspects of time, and that makes writers traditional. Even in his younger days, Eliot paid much attention to the passing of the year, the withering of flowers, the coming of old age, and he was constantly preoccupied with the problem of time. Eliot expressed his conception of religion as a fragmentary unit, not as a whole or unified deployment in the early poetry. But we can find his fundmental attitude of religions as we apporoach his later poems, escepially in four quartets which explored the subject of the time and the timeless. The union of time and timeless is, Eliot suggests, to be the paracoxical chrisliam view of the incarnation. According to the idea of christan Incarnation, a timeless God is of no use to us, and a temporal god would be as much caught in the flux as we are. christianity presents us with the conception of a timeless god substantially entering time, a paradoxical and " impossible union" which was achieved once for all by incarnation. And he expressed in 'Burnt Norton' that the timeless can be conquered only through time though the timeless is very hard to catch because of the temporal world. In some sense, we can only say to experience the Eternity, or the still point which trancends the temporal ; it is by giving uf of our desire, by action and suffering ; to rise up to god, but with no physical action ; and to understand both the timeless and temporal at the same time.

광양만과 여수해만의 표층퇴적물에서 Nonylphenol의 오염에 관한 연구

조현서,김용옥,설순우,-- 한국환경과학회 2004 한국환경과학회지 Vol.13 No.6

This study was carried out to survey the pollution of nonvlphenol (NP) in surface sediments around Gwangyang bay and Yeosu sound. NP was suspected chemicals as endocrine disruption. Gwangyang bay is located on the mid south coast of Korea. It is a semi-closed bay which Yeosu petrochemical industrial complex, POSCO (Pohang Steel Company) and Gwangyang container harbor are there. The surface sediments were collected at 15 stations with gravity corer at October, 1999, February, May and August, 2000. Also, the stream and intertidal sediment were collected at 5 sites at August, 2000. Concentrations of NP in surface sediments were in the range of 6.89 to 202.70 ng/g dry wt.. Seasonal range (mean value) of NP is 13.98 to 30.48 (23.46) ng/g dry wt. at October, 10.35 to 54.91 (28.10) ng/g dry wt. at February, 29.05 to 202.70 (82.32) ng/g dry wt. at May and 6.98 to 83.40 (25.37) ng/g dry wt. at August. NP was seasonally fluctuated, and the highest mean value and range was detected at May, 2000. NP was highly distributed in the inner part of Gwangyang bay than Yeosu sound. Concentrations of NP in stream and intertidal sediments showed the highest value in downstream near Yeosu petrochemical industrial complex and Yondung stream. It suggests that the source of NP is industrial wastewater and municipal sewage.

This study was carried out to investigate whether the dietary cholesterol enhance the fecal excretions of neutral steriods and bile acids in human. During the experimental period, 14 healthy Korean women were supplemented 2 egg yolks for 1 week and 4 egg yolks for another 1 week to thier usual diet. Cholesterol intakes of the subjects consumed the usual diet were 201.1∼238.0 mg, those were 633.1∼660.2 mg when the subjects were supplemented 2 egg yolks and those were 1077.3∼1198.8 mg when they were supplemented 4 egg yolks. Feces weight and total lipids excretion were not responded to supplementation of egg yolks. Fecal neutral steriods excretion was enhanced by supplementation of egg yolks, but the increment was not great considerably. But fecal excretion of bile acids was not enhanced by supplementation of egg yolks. These findings suggested that the enhance of fecal neutral steriods and/or bile acids excretions is not main mechanism to maintain normal plasma cholesterol level when cholesterol intake is increased in human.

An understanding of the mechanism of healing has increased dramatically during the past decade. The phenomenon of epithelization is important in the normal resurfacing of a donor site or a partial thickness burn wound. This study was conducted to clarify the effect of epidermal growth factor in wound healing of human. Paired donor sites were created in 18 patients who required skin grafting for either burns or reconstructive surgery. One donor site from each patient was treated topically with silver sulfadiazine cream, and the other was treated with silver sulfadiazine cream containing epidermal growth factor(10ug/ml) (Human recombinant epidermal growth factor ; Sigma, St.Louis, Mo). The donor sites were photographed daily, and healing was measured with the use of planimetric anlysis. The donor sites treated with silver sulfadiazine containing epidermal growth factor had an accelerated rate in all 18 patients as compared with that in the paired donor sited treated with silver sulfadiazine alone. Combining data from all patients demonstrated reduced the average time to 100% healing by approximately 2 to 3 days (p<0.01). Light and electron microscopical study of biopsy specimens taken from the centers of donor sites three days after the onset of healing supported these results. In conclusion, epidermal growth factor accelerates the rate of healing of partial thickness skin wound.

T.S.Eliot의 Ariel Poems에 나타난 宗敎觀

김현옥 호남대학교 1999 호남대학교 학술논문집 Vol.20 No.1

As in james Joyce or Ezra Pound, we find in T.S.Eliot a poet who lays a keen analysis on the infirmities of hollowness and disorder in the 20th century. In his poetry Eliot saw a world in which all the established values were demolished. The world of Eliot's poetry reflects his spiritual transformation as a Christian writer. He wished to acquire and establish a meaning way of life which renders a way to escape from the chaos of doubt, frustration and disappointment which spread all over the world in the 20th century. His conflicts with the Christian tradition can be a proper clue with which we may approach to the understanding of Eliot's poetic world. This thesis has analyzed the Christian elements in the poetry of T.S.Eliot with special reference to his conversion from Christianity and treats the conviction in redemption, the desire for a new spiritual life, the joy of salvation, regeneration and the new life. In poetry form and content cannot be separated: the notion of form without content, or of content ignorance form, is an illusion, for the meaning of a poem exists in the words of the poem and in those words only. Eliot's poetry achieves " a complete consort dancing together in terms of content and form through various poetic techniques. Content in poetry ,however, is closely related to the human society, to the writer's experience of life, and to his religious and philosophical thoughts. Eliot's philosophical ideas and religious experiences in his poetry deepened, as his Christian belief developed towards his conviction of salvation and regeneration.

詩人으로서 T.S.Eliot의 發展過程(Ⅰ)

金炫玉 湖南大學校 1990 호남대학교 학술논문집 Vol.11 No.1

True to the tradition of Christianity, Eliot believes that the progress of the human soul and its redemption depends on its ability to apprehend the Eternal felt in time and remembered in time. Although we may have fleeting moments of enlightenment, in which the timeless impinges on time, a fuller union and a deeper communion with the Divine is possible only through a lifelong endeavour and discipline. This communion with the Divine not only brings salvation to the human soul but also completes the cycle of life by. transfiguring into a pattern the rhythm of our existence and the order of creation and thus brings peace, happiness and joy to mankind through a satisfaction of the whole being. The progress of Eliot as a poet from “The Love Song of J. Alfred Prufrock” to Four Quartets may be said to be the progress of the intellectual soul, for in his poems there is what Highet rightly calls’ a negative and largely papan soul building itself into a sincere and Christian and self-forgetting soul: a heap of ruins reconstructing itself into a shrine’. The concluding lines of “ the Little Gidding” may be said to be a philosophical summing up of the ideas of Eliot on time, history and on the redemption of man. According to Eliot, the spiritual exploration through time and eternity always takes us to the same destination which is the point of the intersection of the timeless with time. Life for Eliot is an eternal cycle of birth and death and in order to understand the mysteries of birth, we must have the knowledge of death. History, which is a pattern of timeless moments, is part of this eternal cycle ane the lives of human beings are significant in so far as they form an integral part of this pattern of timeless moments of history.

The Waste Land의 狀況硏究 Ⅰ

金炫玉 호남대학교 1986 호남대학교 학술논문집 Vol.6 No.2

This paper is an attempt to appreciate the context of The Waste Land of T.S.Eliot's masterpiece. Eliot says of The Waste Land itself that not only the title, but the plan and a good deal of the incidental symbolism of the poem were suggested by Miss Jessie L. Weston's bok on the Grail Legend: From Ritual to Romance (1920) and Sir James Frazer's the Golden Bough(1890-1915). He has used especially the twoi volumes, Adonis, Attis, Osiris in the book. Arthurian romances of the quest for the Holy Grail are under lain by pre-Christian fertility myths and ritual such as those described by Frazer. In teh Arthurian legend a Fisher King (the fish being an ancient symbol of life) has been maimed or killed, and his country has therefore become a dry Waste Land; he can only be regenerated and his land restored to fertility by a Knight(Perceval or Parsifal) who perseveres through various ordeals to the perilous Chaped and learns the answersto certain ritual questions about the Grail. The Fisher King is seen as analogous to vegetation gods such as Adonis of greece, Attis of Phrygia, Osiris of Egypt, and perphaps also the Greek deity Hyacinthus.

비교반응이 감귤생육에 미치는 영향

金荊玉,吳現道 제주대학교 1971 논문집 Vol.3 No.-

Citrus growing in Cheju-do, Korea has increased remarkably for the past several years. In 1971 the citrus acreage in Cheju-do will have increased to 150,000 acres(6,000 hectars). To avoid frost, citrus growing in Cheju-do is confined to the coastal area below 200 metes avove sea level. The average orchard size is limited to small unit size. This has necessitated a high level of attention to individual tree health and production in orchard management. But in Cheju-do citrus farmers have not been able to solve various problems corretly in order to obtain maximum yield with high quality. Therefore, the solution of these problems necessitates the use of the systematic application methods fertilizers to citrus. From the experimental results of the application of some fertilizers to citrus unshu and the analysis of leaves, we gained important knowledge regarding citrus unshu. The effectiveness of fertilizers was studied under normal field conditions and with pot experiment in the field. The amount of fertilizer applied as base fertilizer was divided into 17 treatment with 8 factors. The effects of nitrogen on the trees were significant increases in height, trunk diameter, number of leaves, and length of branches, but the other mineral nutrient did not show such effect. Through leaf analysis the low calcium concentrations and very high iron and copper concentrations were determined. The first fertilizer applications were made in 1969 and records taken for the period 1970∼1971. This report is only the first presentation of data collected. These studies will be continued through 1974.
