This work intends to study the obligations and liabilities of advising bank in UCP 600. An advising bank has two big obligations as follows : by advising the credit or amendment, the advising bank signifies that it has satisfied itself as to the apparent authenticity of the credit or amendment and that the advice accurately reflects the terms and conditions of the credit or amendment received. An advising bank may utilize the services of another bank("second advising bank") to advise the credit and any amendment to the beneficiary. If a bank is requested to advise a credit or amendment but elects not to do so, it must so inform, without delay, the bank from which the credit, amendment or advice has been received. An advising bank has some problems in connection with the delay of advice and the advice of forged letter of credit.

This study was carried out to compare UCP2 polymorphism, dietary habits, and obesity index in normal and obese university students. The survey was carried out using self-questionnaires collected from the 126 normal and 60 obese university students. The results are summarized as follows. Breakfast was skipped in 43.7% of normal and 49.3% of obesity students and it appeared obese students eat faster than normal students. The percentage of weight control experience were 49.2 and 71.0 in the normal and obese students, respectively. Blood levels of lipid profiles(triglyceride, LDL cholesterol, and HDL cholesterol), hemoglobin, AST and ALT were anaylzed. In UCP2 genes, the frequency of deletion homozygote(DD) was 71.5%, heterozygote(DI) was 26.9% and insertion homozygote(II) was 1.6%. Plasma levels of triglyceride, total cholesterol, LDL cholesterol, and HDL cholesterol of normal students were 79.06, 172.25, 100.86 and 57.03 mg/dl, and those of obese students were 93.06, 173.22, 101.22 and 54.39 mg/dl, respectively. Blood parameters were in normal range in both group. Plasma triglyceride, total cholesterol and LDL cholesterol levels of obese students were higher than those of normal students. On the other hand, plasma HDL cholesterol levels of obese students were lower than those of normal students. Plasma levels of AST and ALT were in normal range in both group. However, AST and ALT levels of obese students were higher than that of normal students. Thus, it was recommended for them to have a nutritional education program to improve their dietary and living habits for obese students’health. Nutritional education program should also be organized practically and systematically.

As part of a fundamental study on the volume reduction of contaminated concrete wastes, the separation characteristics of the aggregates and the distribution of the radioactivity in the aggregates were investigated. Radioisotope $^{60}Co$ was artificially used as a model contaminant for non-radioactive crushed concrete waste. Volume reduction for radioactively contaminated dismantled concrete wastes was carried out using activated heavy weight concrete taken from the Korea Research Reactor 2 (KRR-2) and light weight concrete from the Uranium Conversion Plant (UCP). The results showed that most of the $^{60}Co$ nuclide was easily separated from the contaminated dismantled concrete waste and was concentrated mainly in the porous fine cement paste. The heating temperature was found to be one of the effective parameters in the removal of the radionuclide from concrete waste. The volume reduction rate achieved was above 80% for the KRR-2 concrete wastes and above 75% for the UCP concrete wastes by thermal and mechanical treatment.

It has been reported that CLA decreases fat deposition in vivo and in vitro experiments. Among CLA isomers, c9t11 and t10c12 have been shown to exert active biological activities. For example, t10c12 reduces body weight and increases lean body mass, whereas, c9t11 has little effect on body fattness. However, the underlying molecular mechanism for the anti-obesity action of CLA isomers are not well understood. The purpose of this study was to examine the effects of t10c12 and c9t11 on lipid accumulation, cell proliferation, cell death and the expression levels of Ucp genes which are proposed as targets for anti-obesity in 3T3-L1 preadipocytes. Isomers of CLA at 50$\mu$M were added into preadipocyte differentiation medium for 3, 6 and 9days. Control cells received only the vehicle in the differentiation medium. Cytochemical analyses for lipid accumulation, cell proliferation and apotosis were carried out to compare lipidogenesis and cellular activity. RT-PCR analysis of GAPDH, Ucp 2,3 and 4 were also performed to find any modulatory effects of CLA isomers on the metabolic genes. Lipid accumulation indicated by Oil Red-O staining was inhibited in CLA isomers as compared to the control. T10c12 isomer showed less lipidogenesis than c9t11 did. A decrease occurred in CLA isomers as shown by BrdU incorporation. Apotosis has occured at higher level in t10c12 when compared to that of t9c11. Ucp 2, 3 and 4 genes were also upregulated in CLA isomers. T10c12 showed higher level of Ucp gene expressions than the c9t11 did. The biological activities of CLA isomers were also found to be different during differentiation of 3T3-L1 preadipocytes, suggesting that different isomers may be active in certain stage of lipidogenesis. The results indicate that both c9t11 and t10c12 CLA isomers decrease lipidogenesis, inhibit cell proliferation, increase cell death and upregulate in Ucp gene expressions during 3T3-L1 preadipocyte differentiation. T10c12 isomer was more effective than c9t11 in overall anti-obesity activity.

The objective of this study was to examine diet-induced changes in the expression of UCP2 mRNA in the liver and UCP3 mRNA in the skeletal muscle of mice fed a high-sucrose or high-fat diet. Male ICR mice, aged 4 weeks, were divided into three dietary groups and fed control (N) or modified AIN-76 high-sucrose (US) or high-fat (HF) diets for 12 weeks. The serum total cholesterol (TC) and LDL-cholesterol concentrations of the HF group were significantly higher than those of the N and HS groups. The hepatic TC and triglyceride contents of the HS and HF groups were also significantly higher than those of the N group. The HS diet group had higher serum leptin and insulin levels compared to those of the HF group. Hepatic UCP2 mRNA expression was significantly higher in the HS group than in the N group, but the level in the HF group did not differ from that of the N group. Muscular UCP3 mRNA level was significantly higher in the HF group and especially in the HS group than in N the group. We observed that two gene (UCP2, 3) levels exhibited a similar tendency. These results suggest that UCPs mRNA levels and energy expenditure may be altered or controlled by various dietary patterns. Further research is needed to elucidate the effects of diet on the regulation of many obesity-related genes.

Under Article 2 of the Uniform Customs and Practice for Documentary Credits (1993 Revision. UCP), letter of credit means an arrangement whereby an issuing bank is to make a payment to a beneficiary, or is to accept and pay bills of exchange drawn by the beneficiary, or authorises another bank to effect such payment, or to accept and pay such bills of exchange, or to negotiate, against stipulated document(s), provided that the terms and conditions of the letter of credit are complied with. In letter of credit operations, all parties concerned deal with documents, and not with goods, services and/or other performances to which the documents may relate (UCP, Article 4). It is important to note that under UCP, if a letter of credit contains conditions without stating the document(s) to be presented in compliance therewith, banks will deem such conditions as not stated and will disregard them (Article 13 c). Section 5-108(g) of the Uniform Commercial Code also contains a similar provision. However on several occasions the Korean Supreme Court held that non-documentary conditions in letter of credit governed by UCP could be regarded as valid, although they were not desirable in the context of letter of credit transactions. The rationale underlying the decisions was that parties to the letter of credit transactions are free to determine the terms and conditions of the relevant letter of credit. After reviewing the relevant provisions of UCP, UCC, the International Standby Practices (ISP98) and the Supreme Court decisions of Korea, the author suggests that we classify conditions that do not require any documents (so called apparent non-documentary conditions) into two categories and treat them differently. There are apparent non-documentary conditions that are consistent with the nature of letter of credit and those which are inconsistent with the nature of letter of credit. In the first category there are two sub-categories, (i) those which are valid and (ii) those which are invalid and thus should be disregarded. In the second category there are two sub-categories, (i) those which are invalid and thus should be disregarded and (ii) those which are valid but deprive the instrument of the nature as letter of credit.

This study was undertaken to evaluate the effect of bacteria-derived $\beta$-glucan fiber on serum lipids, adiposity and uncoupling protein (UCP) expression in rats. In order to induce obesity, Sprague-Dawley weanling male rats were allowed free access to AIN-76A diet until 4 weeks of age, and fed high-fat diet (beef tallow, $40\%$ of calories as fat) for 6 weeks until 10 weeks of age. Rats were then fed with $0\%$ thigh- fat control group), $1\%$, or $5\%$ bacterial ~-glucan supplemented high-fat diets (w/w) for another 6 weeks. For comparison, normal control group was fed with AIN-76 diet $11.7\%$ fat). Supplementation with bacterial $\beta$-glucan resulted in a significant reduction of high-fat-induced white fat (i.e., visceral and peritoneal fat) development, adipocyte hypertrophy, and development of hyperinsulinemia and hyperleptinemia. Serum triglyceride, total cholesterol, and free fatty acid levels were greatly reduced, but, HDL-cholesterol concentrations were increased by bacterial $\beta$-glucan supplementation. Serum leptin level was lower in the $\beta$-glucan groups than in the high-fat group. The expression of UCPs (UCP1, UCP2, and UCP3) in brown adipose tissue (BAT) were significantly increased by $5\%$ bacterial $\beta$-glucan-containing diet. This study suggests that the anti-obesity effect of $5\%$ bacterial $\beta$-glucan is attributed to upregulation of UCPs and inefficient energy utilization.

We found previously that dietary high fat caused obesity, and levan supplementation to the regular diet reduced adiposity and serum lipids. In the present study, we examined the effects of levan [high-molecular-mass $\beta$-(2,6)-linked fructose polymer] supplement on the development of obesity and lipid metabolism in rats fed with high-fat diet. Thus, to determine whether the dietary levan may have the anti-obesity and hypolipidemic effects, 4-wk-old Sprague Dawley male rats were fed with high-fat diet for 6 wk to induce obesity, and subsequently fed with 0, 1, 5, or 10% levan supplemented high-fat diets (w/w) for another 4 wk. For the comparison, a normal control group was fed with AIN-76A diet. Supplementation with levan resulted in a significant reduction of high-fat-induced body weight gain, white fat (i.e., epididymal, visceral, and peritoneal fat) development, adipocyte hypertrophy, and the development of hyperinsulinemia and hyperlipidemia in a dose-dependent manner. Serum triglyceride and free fatty acid levels were greatly reduced by levan supplementation. Serum total cholesterol level was reduced, whereas the HDL cholesterol level was increased by dietary levan. The expression of uncoupling protein (UCP) was increased by dietary high fat, and was further induced by levan supplementation. The mRNA level of UCP1, 2, and 3 in brown adipose tissue (BAT) and UCP3 in skeletal muscle was upregulated in rats fed with dietary levan. In conclusion, upregulated UCP mRNA expression may contribute to suppression of development of obesity through increased energy expenditure. The present results suggest that levan supplementation to the diet is beneficial in suppressing diet-induced obesity and hyperlipidemia.

본 연구에서는 3T3-L1 전지방세포를 이용하여 발효 삼정환의 지방 분화 억제 효과를 확인하고자 하였다. 삼정환을 5가지 주요 유산균으로 각각 발효시킨 후, Oil Red O 염색법으로 지방세포 분화 억제 여부를 알아보고, 이의 기전을 알기 위해서 지방생성에 핵심적인 역할을 하는 transcription factor 및 지질 조절 효소의 유전자 발현량을 비교하여 보았다. Oil Red O 염색 분석에서는 Lactobacillus plantarum, Enterococcus faecium으로 발효한 삼정환에서 지방구 수의 감소를 확인할 수 있었다. 또한 transcription factor로 $C/EPB{\alpha}$, $PPAR{\gamma}$, UCP-2 및 콜레스테롤 조절과 관련된 효소인 HMG-CoA reductase의 4가지 유전자 발현 정도를 분석하였는데, 발효시키지 않은 삼정환의 경우 농도가 $100{\mu}L/mL$ 이상일 때 네 가지 항목에서 억제 효과를 나타냈으며, 발효시켰을 때는 유산균의 종류에 따라 효과 억제효과가 있었는데, Lactobacillus plantarum으로 발효한 삼정환이 효과가 가장 좋은 것으로 나타났다. Lactobacillus plantarum으로 발효한 삼정환은 동일 농도의 발효하지 않은 삼정환과 비교했을 때, Oil Red O 실험에서 염색된 지방구 수가 더욱 감소하였으며, $PPAR{\gamma}$, UCP-2, HMG-CoA reductase의 경우 농도가 $200{\mu}L/mL$일 때 각각 35%, 57%, 54%로 5가지 발효 삼정환 중 가장 높은 억제율을 나타내었다. 이에 지방분화 억제 효과를 가진 삼정환을 발효시키면 그 효과가 더욱 증가하는 것으로 나타났는데, 특히 Lactobacillus plantarum으로 발효한 삼정환은 $PPAR{\gamma}$, UCP-2, HMG-CoA reductase의 유전자 발현조절을 통해 지방 분화를 억제시키는 것으로 밝혀져 발효 삼정환은 항비만 혹은 항고지혈증 약물로 개발 가능성이 있는 것으로 사료된다.
