The system of commercial letter of credit is to provide a means of payment for goods and services supplied by a seller to a buyer, usually facilitate dealings between merchants domiciled in different countries by ensuring payment to the seller for the contract of goods or services on the one hand and their delivery to the buyer on the other. It is in overseas commerce that the commercial letter of credit plays a leading role. When trader has confidence in trader foreign trade tends to be financed more on the basic of the collection of a bill of exchange, which may be cheaper. The act by which the beneficiary of an irrevocable documentary letter of credit entitles himself to payment according to the promise embodied in the credit in the tender by him with in the validity period of the credit of documents complying in all respects with the credit terms and conditions that are a pre-requisite to payment. In this way the transaction of foreign commerce in the commercial letter of credit is not made by goods and services but made by made by documents between a1I parties concerned. Insurance documents consist of the important parts of documents on the letter of credit. In connection with the above circumstances, it will be valuable that the review of the revised insurance articles on the commercial letter of credit and comparision between the insusance articles on the letter of credit and the related articies on the institute Cargo Clauses. Therefore the puspose of this thesis is to review the insurance articles of the commercial 1etter of credit in 1983, and to compare with the related articles of Institute cargo Clauses, 1982 and to find the differences between them. In addition it is intended to suggest several complementary points of the letter of credit. This thesis consists of five chapters. The contents are as follows; 1st chapter is the introduction of this thesis, second chapter the reasons and particulars of the U.C.P,third chapter the related Articles of the insurance documents on the U.C.P. in 1983, forth chapter the comparision between this articles of insurance and the related articles of Institute Cargo Clauses, fifth chapter in conclusion which suggest the complementary points of Insurance Articles of the commercial letter of credit.

본 연구에서는 전남 무안지역을 중심으로 1995년 8월부터 1997년 12월의 총 884일 기간 동안 관측된 CO$_2$ 농도자료와 국외 주요 배경대기관측지점에서 관측된 농도자료를 토대로, CO$_2$의 단주기적 변화경향성에 대한 지역적 차이를 비교 해석하였다. 동기간 동안 무안지역에서 관측된 이산화탄소의 전체적인 일평균 농도는 374.5${\pm}$6.6ppm으로, 그리고 계절별로는 378${\pm}$5.2 (봄: N= 181), 372${\pm}$10.2 (여름: N=210), 372${\pm}$7.2 (가을: N=243), 376${\pm}$5.4ppm (겨울: N=206)의 평균치로 나타났다. 무안지역을 중심으로 관측된 일주기 경향성을 포인트 배로우(Point Barrow)를 위시한 주요 외국 관측점들과의 결과와 비교하였을 때, 단순히 일주기 중심의 경향성 (주야간대의 농도차이)에 덧붙여, 계절적 요인의 작용으로 인한 일주기의 계절별 변화요인 (진동폭 변화, 최고농도의 형성 시점 등)이 지역별로 다양하게 나타난다는 점을 확인하였다. 특히 무안지역은 주야간대의 주기를 중심으로 볼 때, 여타 지역과는 정반대로 주저야고의 경향이 뚜렷하였다. 그리고 일주기를 다시 계절적으로 비교하였을 때, 일일 내내 비교적 고농도가 지속되거나 (봄, 겨울철), 상대적으로 낮은 농도가 24시간동안 지속되는 경향 (여름, 가을철)으로 뚜렷하게 구분되었다. 이는 겨울철 연료의 과배출, 중국대륙으로부터 오염물질의 유입여부 등 연구지역 주변환경의 계절별 오염양상, 공기순환, 기상변화, 식생의 변화 등이 복합적으로 작용하여 나타나는 결과로 보인다. 이러한 결과들을 토대로 볼 때, 여타 요인들에 비해 무안지역은 인위적 오염원의 영향이 강하게 작용하는 것으로 사료된다. 따라서 무안지역을 중심으로 한 농도변화의 경향성에 대한 해석은 여타 외국의 주요 관측점에 대한 결과와 달리, 한반도를 포괄하는 광역적인 차원의 배경농도를 대표하는 것이 아니라, 무안지역을 중심으로 보다 국부적인 차원에서 진행되는 농도변화를 반영하는 경향이 큰 것으로 추정된다. 그렇지만 이러한 경향이 한반도에 광역적으로 나타나는 현상일 가능성도 배제할 수 없다. 이에 대한 판단은 안면도를 중심으로 후속적으로 진행된 연구결과들에 대한 면밀한 검토가 수반되어야 할 것으로 보인다. This study was conducted to analyze the patterns associated with the short-term variability of CO$_2$ concentrations over 24-h scale within and across the Korean Peninsula. In the course of our study, we compared the data sets obtained from Moo-Ahn (MAN) station located in the far western coastal area of Korea with those determined from major background observatory stations around the world from the periods of Aug. 1995 to Dec. 1997. The mean CO$_2$ concentration of the MAN area for the whole study periods, when computed using the daily mean values, was found out to be 374.5${\pm}$6.6 ppm (N=884); seasonal mean values were found out to be 378${\pm}$5.2 (spring: N=181), 372${\pm}$10.2 (summer: N =210), 372${\pm}$7.2 (fall: N=243), and 376${\pm}$5.4 ppm (winter: N=206). When the data from MAN was compared with those of major background stations, the effects of both daily and seasonal components appear to vary distinctively across different stations. Those effects are expected to reflect the mixed effects of various factors which include: seasonal pollution patterns, weather conditions, vegetation, and so forth. Based upon this comparative analysis, we suspect that the MAN area is under the strong influence of anthropogenic source processes relative to all the other stations under consideration. If that is not the case, the existence of enhanced CO$_2$ level may be rather ubiquitous phenomena in Korea. More detailed inspection of CO$_2$ behavior from various respects is strongly desired in the future.

Conjugated linoleic acid (CLA) is a group of positional and geometric isomers of conjugated dienoic derivatives of linoleic acid. CLA has been reported to be able to reduce body fat. In this study, we investigated the antidiabetic effect of fermented milk (FM) containing CLA on type II diabetes db/db mice. Mice were treated with 0.2% low FM, 0.6% high FM, or Glimepiride (GLM) for 6 wk. Our results revealed that the body weight and the levels of fasting blood glucose, serum insulin, and leptin were significantly decreased in FM fed mice compared to db/db mice. Oral glucose tolerance and insulin tolerance were significantly ameliorated in FM fed mice compared to db/db mice. Consistent with these results, the concentrations of serum total cholesterol, triglycerides, and LDL cholesterol were also significantly decreased in FM fed mice compared to db/db mice. However, the concentration of HDL cholesterol was significantly higher in FM fed mice compared to db/db mice. These results were similar to those of GLM, a commercial anti-diabetic drug. Therefore, our results suggest that FM has anti-diabetic effect as a functional food to treat type II diabetes mellitus.
