This article aims at analysing the reality of banks' liability resulting from the breach of contract on its part to keep the business secrecy with the supplier in the transferable credit, focusing on a English decision, Jackson v. Royal Bank of Scotland [2005] UKHL 3. In this case, the applicant, 'Econ', had purchased various varieties of pre-packed dog chews in bulk through 'Sam'(lst beneficiary) from 'PPLtd'(2nd beneficiary) in Thailand, using a transferable letter of credit issued by 'RBank'. 'Sam' charged a tremendous amount of mark-up on each transaction and it had not been disclosed to 'Econ', although the identity of 'PPLtd' was revealed to 'Econ' by various documents. However, 'RBank' made an unfortunate error to send an completion statement and other documents including 'PPLtd.'s invoice to 'Econ' instead of to 'Sam'. The effect of the Bank's error was to reveal to 'Econ' the substantial profit that 'Sam' was making on these transactions. CEO of 'Econ' was furious and, as a result, decided to cut 'Sam' out of its importing system and terminated their relationship. 'Sam' sued 'RBank' for damages to recover the loss of profits which could have been possibly made, if the information on the mark-up would not have been exposed to 'Econ'. The House of Lord held that 'RBank' was in breach of its duty of confidence, so 'Sam' was entitled to recover damages on a decreasing scale over 4 years, since there was no specific undertaking from the letter of credit.

High resolution satellite images have to be oriented and geometrically processed from GCPs(Ground Control Points) to generate precise DEMs(Digital Elevation Models) and topographic maps. In Korea, thousands of national UCPS(Unified Control Points) are established and distributed all over the country by the Korean NGII(National Geographic Information Institute). For that reason, UCPs can be easily searched and downloaded by the national-control-point-record-issues system. Following the study, we suggested the sky-view and road-view from web-portals for searching and identifying UCPs on the images. To evaluate the usefulness of UCPs in RPCs(rational polynomial coefficients) adjustment of the high resolution satellite images, the one UCP, which of using simple the control point, has been applied to adjust the vendor-provided RPCs of the KOMPSAT-3 images. As a result, the positioning error of corrected RPCs was approximately one pixel and one meter. From this experiment, we conclude that the UCPs will be able to replace the survey GCPs for mapping with the satellite images or aerial images.

배경: AT$_1$수용체의 길항제가 세포 수준에서 심근을 재관류 손사으로부터 보호할수 있다는 것으로 알려져 있지만, 생체내에서의 효과나 그 기전은 아직 명확히 밝혀지지 않았다. 본 연구에서는 백서 심근 허혈 모델을 이용하여, AT$_1$ 수용체의 길항제들 중 하나인 irbesartan이 심근이 재관휴 손상에 미치는 효과를 알아보고, 재관류 손상을 매개하는 한 각지 기전으로서 세포자멸의 기여에 대하여 연구하고자 하였다. 대상 및 방법: Sprague-Dawley 백서에서 무작용 부형약(10% gum arabic: 1군, 개체수=14관) irbesartan(50mg/kg/day :II 군, 개체수=12)을 각각 3일 동안 24시간마다 경구로 투여하였다. 실험동물의 좌 관상 동맥을 45분간 결찰하였다가, 그 후 2시간 동안 재관류시킨 다음 심장을 적출 하였다. TTC(triphenyltetrazolium chloride) 염색법을 이용하여, 허혈 노출 부위에 대한 심근 경색 부위의 비율을 측정하였다. Agarose gel 전기영동상의 DNa 분절 양상과 TUNEL(TdT-mediated dUCP nick end labeling) 염색을 관찰하여 세포자멸이 일어난 정도를 평가하였다. 세포자멸을 조절하는데 관여하는 것으로 알려진 Bcl-2(B-cell lymphoma 2 gene), Bad 등의 단백과 ERK (extracellular signal-regulated kinase), p-38 등 신호전달체계에 작용하는 MAPKs(mitogen-activated protein kinases)의 발현을 측정하기 위하여 Western blot을 시행하였다. 결과: 허혈 노출부위에 대한 심근 경색부위의 비율은 II군(42$\pm$2.7%)이 I군( 64.1$\pm$4.65)에 비해 유의하게 작았다.(p< 0.05), Agarose gel 전기영동상의 DNA laddering 양상은 I군에서 보다 높게 발현되었다. Bad와 ERK2의 발현은 두 군간에 유의한 차이가 없었다. 결론: AT$_1$수용체 길항제인 irbesartan은 생체에서 심근의 재관류 손상을 줄이는 효과가 있었다. 이 효과는 적어도 부분적으로 나만 심근세포의 세포자멸이 감소한 것에 기인한 것으로 설명할 수 있으며, 이 항-세포 자멸 효과는 Bcl-2의 발현증가와 관련이 있는 것으로 추정되었다.

Obesity, represented by abnormal fat accumulation due to an imbalance between energy intake and expenditure, is a major public health issue worldwide, leading to multiple noncommunicable diseases, including atherosclerosis, hypertension, type 2 diabetes, and cancer. Diverse solutions have been proposed to combat obesity. Attention has focused on two types of adipose tissues as a promising therapeutic target in obesity: traditional brown and beige or brite. Unlike energy-storing white adipose (endocrine) tissue, traditional brown adipose tissue and beige adipose tissue have energy-dissipating thermogenic properties. Both types of tissue are present in adult humans and inducible through external stimuli, such as cold exposure, ${\beta}3$-adrenergic receptor agonists, and phytochemicals. Among these stimuli, microbiota present in the human intestinal tract participate in multiple metabolic activities. Modulation of gut microbiota may offer a potent and possibly curative strategy against various metabolic diseases. Numerous studies have focused on the effects of established antiobesity treatments on the gut microenvironment or brown-adipose-tissue activation. In this review, we focus mainly on stimuli known to alleviate obesity, weight gain, and metabolic diseases, in addition to known and possible inter-relations between gut microbiota modulation and similar interventions and adipose tissue browning. The findings may pave the way toward new strategies against obesity.

The purpose of the study was to compare the effect of either moderate or high intensity aerobic exercise on inflammasome, M1, M2 macrophage infiltration and brown adipocyte markers in subcutaneous adipose tissue of the high fat diet-induced obese mice. The 4 weeks male C57BL/6 mice were randomly assigned to four groups: normal diet control (NC; n=10), high-fat diet control (HC; n=10), high fat diet with moderate intensity exercise (HME; n=10), or high fat diet with high intensity exercise (HIE; n=10) groups. The high fat diet was given 60% calories from fat whereas normal diet was given 18% calories from fat. The moderate intensity exercise group (HME) was set at 10m/min in the first 2 weeks, 12m/min in 3-5 weeks and 14m/min in 6-16 weeks and the high intensity exercise group (HIE) was set at 14m/min in the first 2 weeks, 17m/min in 3-5 weeks and 18m/min in 6-16 weeks. The semi quantitative reverse transcription-polymerase chain reaction (RT PCR) was used to analyze the gene expression. The moderate intensity exercise significantly reduced the expression of NLRP3, F480, CD11c and CD86. Further, the moderate intensity exercise significantly increased CD206 and $PGC1{\alpha}$, BMP7 and PRDM. The high intensity exercise significantly reduced NLRP3, CD11c and CD86. Further, the high intensity exercise significantly increased $PGC1{\alpha}$ and BMP7. In conclusion, moderate intensity exercise has more positive effects on inflammasome, M1, M2 macrophage infiltration and brown adipocyte maskers compared to high intensity exercise in high fat diet induced obese mice.
