본 연구는 2000년 1월부터 2008년 말까지 콜금리, 3년물 국채금리, 원달러 외환시장 및 KOSPI자료를 이용하여 원달러 환율 및 장단기 금리 변화량, KOSPI수익률사이의 동적연관성을 실증적으로 분석하였다. 실증분석결과 첫째, 콜금리와 원달러 외환시장사이에는 장기적인 균형관계가 존재하고 있으나, 콜금리와 KOSPI, 원달러와 KOSPI사이에는 장기적인 균형관계가 존재하지 않는 것으로 나타났다. 3년물 국채금리는 콜금리와 공적분관계가 있으나 원달러, KOSPI와는 공적분관계가 존재하지 않는 것으로 나타났다. 둘째, 3년물 국채금리는 KOSPI 및 원달러 환율간에는 피드백적인 관계가 존재하고 있으나, 3년물 국채금리의 KOSPI 및 원달러에 대한 영향력이 그 반대의 경우보다 상대적으로 더 강한 것으로 나타났다. 세째, KOSPI와 원달러 환율사이에도 피드백적인 영향력이 존재하고 있으나 KOSPI의 원달러 환율변화에 대한 영향력이 그 반대의 경우 보다 더 강한 것으로 나타났다. 다섯째, 콜금리는 원달러 외환시장에만 영향력을 미치고 있으며, 장단기 금리사이에는 3년물 국채금리가 콜금리에 대한 영향력을 미치고 있으나 그 반대의 경우는 존재하지 않는 것으로 나타났다. 여섯째, 전반적으로 4가지 금융시계열모두 호재보다는 악재에 더 민감하게 반응하는 정보의 비대칭적인 특성이 존재하는 것으로 나타났다. 이러한 실증분석결과는 투자자들의 투자 및 위험관리전략 수립 뿐 아니라 정책당국자들의 통화 및 금융정책수립에 다소 나마 기여를 할 수 있을 것으로 보여 진다. We try to examine on the short term lead-lag relationship between call, KOSPI and won dollar spot markets with a vector error correction model, Granger causality test and impulse response analysis. This paper uses daily return data covering from January 2000 to December 2008. The major results are as follows; First, according to empirical test based on the Granger causality, the returns of won/dollar spot market Granger causes call market but vice versa. Second, we find a bilateral influence between won/dollar and KOSPI spot markets but the impact of KOSPI is relatively more dominant than of that of won/dollar market. Third, we also find that there is no influence between call and KOSPI markets in a statistically significant level. We hope these kinds of empirical results might be helpful for the investors to set up a asset portfolio and risk management system.

In order to clarify the existence of the non-selective cationic channel of CI^- -channel in gastric antral smooth muscle cells which suggested to play a critical role in generation and maintenance of depolarization and exitability, the whole cell mode of patch-clamp experiment was conducted. Following results were obtained ; 1. Puff injection of caffeine induced the increase of inward currents in the hyperpolarized holding potential ranges, and the increase of outward currents in the hypopolarized range. 2. In the case of blocking of all known currents, these current components were observed. 3. These current components were disappeared when known as a Cl^- -channel blocking agent was treated and intracellular EGTA concentration was increased. The above results could be concluded that these current components strongly suggested as a Ca^2+ -dependent Cl^- current in the gastric antral smooth muscle cells.

This work was carried out to investigate the acid producing activity, tolerance and other important characteristics of the strains isolated from the market yogurt drinks (fermented milk or fomented milk drinks) and lactic bacterial drugs (control agent of entero-bacteria). And obtained results were as in the followings. 1. Almost of the strains isolated from market yogurt drinks were identified as Lactobacillus bulgaricus and two of them were Lactobacillus acidophillus. The specially aerobic strains isolated from lactic acid bacterial drugs were identified as Bacillus subtilis and anaerobics were Clostridium butylicum, Sporolactobacillus inulinus, Streptococcus faecalis and Bifidobacterium bifidum. 2. Concentration of active lactic acid bacteria of the market yogurt drinks was found almost as same level, and decreasing tendency of the concentration was commonly seen in every samples during hot summer (high temperature over 35℃). Acid producing activity of some stronger strains continued for 10 days and weak strains for 6 days in summer. 3. During 6 months of the test period, not any contamination case of pathogenic enter-obacteria was found in market yogurt drink samples. 4. But yeast contamination was so aboundantly seen that the ratio of contaminated case was attained to about 20% in fermented milk and to 80% in fermented drink samples. 5. Maximum acid production of the strains isolated from market yogurt drinks was attained to almost 2.0%, but that of the strains from tactic acid bacterial drugs was less than 0.7% except the Str. faecalis strain. 6. Curd forming and acid producing activities of both L. bulgaricus strains and L. acidophillus strains were almost as same level. And the activities continued for 15 days at temperature of 5℃ and pH of 4.0, but for 7 days at high temperature of 35℃. 7. In high temperature (over 35℃) and loll pH condition (less than 3.6), the old culture of homo fermentative lactic acid bacterial strains isolated from market yogurt drinks were more easily changed to hetero fermentative strains than the young culture of the strains.

Tamna, the old name of Cheju Province of Korea, was in old times a sea-girt tribal state south of the southern tip of the Korean peninsula. Although there is no clue as to the exact date of its foundation, Tamna is presumed to have been in contact with the mainland even in the greatly remote past, and about the fifth century the government of Tamna had some formal connections with those of Shilla and Paekjae, and some inhabitants of the island made long voyages for commercial or other purposes as far as Koryo, Japan, and China. Owing to its geographical situation and historical background, ancient Tamna was backward in every aspect of its civilization. On the other hand, however, this peculiar environment has served to preserve most of the antiquities of Tamna which are now attracting an increasing attention of the students concerned. This article tries to show some aspects of the ancient culture of Tamna by studying the origins of its art and science, its language, and its religion. The art and science of Tamna was destined from the beginning to be far from the main stream of those on the mainland because of its geographical location, that is, on isolated island state. However, during the period when the Korean peninsula was divided into three kingdoms, Shilla, Paekjae, and Koguryo, Tamna began to introduce the advanced culture of the mainland through formal and informal intercourse with the mainland. About the tenth century when the whole peninsula was put under the rule of the Koryo dynasty, Tamna was influenced by a scholarly atmosphere in the capital of Koryo with the Koryo's increasing influence upon the island, and produced some men of learning who placed himself at the service of the royal court. This tendency toward learning in creased during the period from the tenth to the fourteenth century. Although there broke out on the island during the period an armed rebel, called the Rebellion of Sambyolcho, against the central government, it also made a favorable opportunity for the island to be in closer contact with learned circles in the capital of the Koryo kingdom. During the fifteenth century Tamna began to enjoy more scholarly atmosphere than before. This is because the Yi dynasty following Koryo established "hyanggyo's" or Confucian schools with a view to promoting the love of learning. As a result Tamna produced a number of learned men. But almost all of them followed the course of scholars in the capital, scarcely paying attention to literature and art peculiar to the island. As for language as spoken in Tamna, it seems to have come down from the language of ancient Koryo. Tamna the name of the island state, and Yang Eulla, the name of one of the three ancient tribes of the island, show that, according to the results of the authors' investigation, the language of Tamna is closely related with that of primitive Koryo. This close relationship is to be seen especially between the names of tribes of Tamna and those or the five tribes of ancient Koryo. The primitive religion of Tamna was shamanism in which shamans and conjurers played decisive roles. Later Buddhism was introduced into the island and during the Koryo dynasty Koryo and Yuan, an ancient kingdom of China which once occupied Tamna, both adopted a pro-Buddhist policy and propagated Buddhism on the island. As a result, Buddhism throve all over the island. However, most priests did not apply themselves to the Buddhist doctrine, but was chiefly engaged in prayer for earthly happiness of inhabitants of the island. Consequently it can be said that religion of those days was a fusion of Buddhism and shamanism.

The purpose of this study was to determine gain the most desirable mixture ratio for the ingredients of Backhapbyung. Sensory examination and mechanical test were conducted on the texture, water contents and color degree of Backhapbyung with various ratios of liliibulbs powder and sugar added to nonglutinous rice flour. The results of sensory evaluation showed that Backhapbyung composed of put 8% (24g) liliibulbs powder, 40g sugar, 40ml water and 276g nonglutinous rice flour had the highest overall score in terns of acceptability, after-swallowing and taste of flavor, and overall quality preference. Overall among the recipes tested, that with 6% (24g) liliibulbs powder, 40g sugar, 40m1 water and 282g nonglutinous rice flour showed the highest marks in springiness, cohesiveness, gumminess and chewiness. The moisture content was 33.54% nonglutinous rice flour, and 11.8% liliibulbs powder. The overall quality of sensory examination for bitterness was positively correlated with the hardness of sensory examination and the mechanical examination for adhesiveness. The overall quality of sensory examination for chewiness was positively correlated with the moistness of sensory examination and the mechanical examination for cohesiveness. From the above results, the best mixture ratio of Backhapbyung, with a moisture content of 37.18%, is 8% (24g) of liliibulbs powder, -10g sugar, 40ml water, and 3g salt and 276g nonglutinous rice flour.

Seasonal Fluctuation and Vertical Microdistribution of Drosophilid Flies Dwelling in the Broad-leaved Forests on Cheju-do(Quelpart Island)

김원택,김승범,정세호,강효식 濟州大學校 師範大學 科學敎育硏究所 1995 科學敎育 Vol.12 No.1

Community organization of the drosophilid flies was investigated with respect to the seasonal variation in species abundance and vertical microdistribution on the basis of the trapped collections in the two natural forests on Cheju-do from May to October 1994. The dominant species were Drosophila bizonata. D. curviceps. D. lutescens. D. angularis. D. pengi. and D. immigrans in the annual collections. The pattern in seasonal changes of the dominant species was similar at the two survey sites. Seasonal fluctuation in the species diversity was more affected by evenness than by species richness (number of species). The seasonal variation of abundance showed an unimodal pattern in all of the dominant species. The seasonal patterns of vertical microdistribution revealed difference in some of the dominant species between the two survey sites. These results suggest that the predominant species in the forest avoid niche overlap by means of seasonal separation of breedings and that the vertical microdistribution is strongly affected by factors associated with season and vertical site in the deep wooded forests.
