This Study analyzes the fact that whether or not, the applicant, by failing to object promptly to the facial discrepancies of the presented documents and to return those documents to the issuing bank, has waived his right to sue for breach of the Application agreement based on the recent Korea-US Case law. Some commentators claim that an applicant has a duty to notify the issuing bank within a reasonable time after receiving the documents that they do not comply with the letter of credit requirements and to return those documents to the issuing bank, and also suggest that a failure to do so result in a waiver of discrepancies that operates as a matter of law. But such decisions make little sense in letter of credit transaction. Unless otherwise agreed, Applicant agreement does not require that the applicant notify the issuing bank of any facial discrepancies of the documents or return those documents. Moreover there is no support in the body of law, i.e., UCP 500 or the Revised UCC Article 5, for an automatic waiver or preclusion arising from the applicant's failure to object promptly. In addition, beyond the lack of authority to support an automatic waiver arising from the applicant's failure to object and return the documents, in a letter of credit transaction the issuing bank is the only party charged with the duty of scrutinizing documents. Therefore, if there are discrepancies, it is the bank that should have to seek an express waiver from the applicant ; the issuing bank should not avoid responsibility for failing to notice discrepancies because the applicant was slow to scrutinize the documents closely or because the applicant failed to inform the issuing bank of such discrepancies. Requiring that applicants inspect documents independently defeats the purpose of retaining the issuing bank, erodes the bank's responsibility to perform its role diligently, and may result in the bank avoiding liability despite negligent payment. If the bank wants to require an applicant to report discrepancies promptly, he may include a provision in the Application agreement limiting the time limit within which the applicant must give notice of facial discrepancies and return the documents. This approach will ensure the continued wide-spread use of documentary credit as a reliable payment mechanism.

Extracting temporal information from documents is becoming more important, because it can be used to various applications such as Question-Answering (QA) systems, Recommendation systems, or Information Retrieval (IR) systems. Most previous studies only focus on English documents, and they are not applicable to the other languages due to the inherent characteristics of languages. In this paper, we propose a new system, named ExoTime, designed to extract temporal information from Korean documents. The ExoTime adopts an external Knowledge Base (KB) in order to achieve better prediction performance, and it also applies a bagging method to the temporal relation prediction. We show that the effectiveness of the proposed approaches by empirical results using Korean TimeBank. The ExoTime system works as a part of ExoBrain that is an artificial intelligent QA system.

Ginsenosides are the principal components responsible for the pharmacological and biological activities of ginseng. Ginsenoside Rd was transformed into compound K using cell-free extracts of food microorganisms, with Lactobacillus pentosus DC101 isolated from kimchi (traditional Korean fermented food) used for this conversion. The optimum time for the conversion was about 72 h at a constant pH of 7.0 and an optimum temperature of about $30^{\circ}C$. The transformation products were identified by thin-layer chromatography and high-performance liquid chromatography, and their structures were assigned using nuclear magnetic resonance analysis. Generally, ginsenoside Rd was converted into ginsenoside F2 by 36 h post-reaction. Consequently, over 97% of ginsenoside Rd was decomposed and converted into compound K by 72 h post-reaction. The bioconversion pathway to produce compound K is as follows: ginsenoside Rd$\rightarrow$ginsenoside F2$\rightarrow$compound K.

The materials on the development of modern architecture in Korea are being collected and organized in a systemic fashion. However, this is not the case with the materials relative to interior design. They are gradually disappearing or being lost. In particular, no serious attempt has yet been made to determine the characteristics and historic value of the interior design of the modern bank buildings. The purpose of this study is to trace the disappearing legacy of the interior design of modern bank buildings by learning the inner space arrangements of these buildings and the characteristics of modern interior design in order to determine the historic significance of modern commercial interior design. Banks of relatively large scale were selected for the purpose of this study. They consisted of: Chosun Bank(1911) and its Andong, Wonsan and Cheongjin branches; Chosun Shiksan Banks and its Busan, Daegu and Pyongyang branches; the Busan branch of the 18 Bank; Dongil Bank, Chosun Savings Bank(1935) and their branches. The study focused on the space arrangements and design characteristics of these banks. Although they aimed at modernization in designingtheir interior spaces, the modern bank buildings were not representative of any particular style of interior design. While western style designs were prevalent, eclectic designs incorporating many different styles existed. The characteristics of the interior design of banks of the time included installation of such decorations and use of high quality construction materials for interior and exterior expressing the wealth as to create an aura of credibility for the banks, while the floor arrangements were relatively stereotyped and simplified.

The Load Tap Changing (LTC) transformer and Shunt Capacitor (SC) bank are major devices for voltage and reactive power control in a distribution substation. Thus, the coordination operation of a LTC transformer and a SC bank is required to achieve better voltage and reactive power compensation at a distribution substation in the same time. This paper proposes coordinate control method of LTC transformer and SC bank to achieve better voltage and reactive power compensation and operation times of these two devices in the same time. The mathematical formulations of the proposed coordinate control method are introduced. Sample case studies are shown to verify the effectiveness of the proposed coordinate control method.

인터넷(ICT)과 은행(금융)이 융합하여 형성된 인터넷전문은행은 핀테크의 결정체라고 불리며 최근 급속한 성장속도를 보이고 있다. 현재 한국의 대표적인 인터넷전문은행으로는 'K뱅크'와 '카카오뱅크'가 있으며, 출범과 동시에 'IT 금융 혁신의 시작'이라는 반응을 얻고 있다. 인터넷전문은행의 편리한 금융서비스를 이용하며 시간적 금융적인 장점을 극대화하는 사용자도 있지만, 신규은행인 단점으로 거래계좌를 검색해도 사기 등의 잘못 악용된 전적을 찾을 수 없기 때문에 중고물품 거래를 악용한 단 한 명의 사기판매자로 인한 피해금액만도 2,000만원을 상회하는 경우도 있다. 본 논문에서는 인터넷전문은행의 최신 동향을 분석하고 피해/긍정사례들을 제시, 분석하며 인터넷전문은행의 피해 예방 방법과 발전전략을 연구, 제안한다.

Cinnamyl alcohol dehydrogenase (CAD, EC 1.1.1.95), catalyzes the reduction of hydroxycinnamaldehydes to give hydroxycinnamyl alcohols, or "monolignols," the monomeric precursors of lignin. Lignins are important components of cell walls and lignified secondary cell walls play crucial roles in long distance transport of water and nutrients during plant growth and development and in plant defense against biotic and abiotic stresses. Here a cDNA clone containing a CAD gene, named as PgCAD, was isolated from a commercial medicinal plant Panax ginseng. PgCAD is predicted to encode a precursor protein of 177 amino acid residues, and its sequence shares high homology with a number of other plant CADS. The expression of PgCAD in adventitious roots and hairy roots of P. ginseng was analyzed using reverse transcriptase (RT)-PCR under various abiotic stresses such as salt, salicylic acid, wounding and chilling treatment that triggered a significant induction of PgCAD at different time points within 2-48 h post-treatment. This study revealed that PgCAD may help the plants to survive against various abiotic stresses.

Ginsenoside $Rb_1$ is the main component in ginsenosides. It is a protopanaxadiol-type ginsenoside that has a dammarane-type triterpenoid as an aglycone. In this study, ginsenoside $Rb_1$ was transformed into gypenoside XVII, ginsenoside Rd, ginsenoside $F_2$ and compound K by glycosidase from Leuconostoc mesenteroides DC102. The optimum time for the conversion was about 72 h at a constant pH of 6.0 to 8.0 and the optimum temperature was about $30^{\circ}C$. Under optimal conditions, ginsenoside $Rb_1$ was decomposed and converted into compound K by 72 h post-reaction (99%). The enzymatic reaction was analyzed by highperformance liquid chromatography, suggesting the transformation pathway: ginsenoside $Rb_1$ ${\rightarrow}$ gypenoside XVII and ginsenoside Rd${\rightarrow}$ginsenoside $F_2{\rightarrow}$compound K.

Crowbar system is usually applied to a pulsed power system in which a capacitor bank is discharged into a load. This provides a free wheeling path for the load current and prevents the capacitor from recharging due to a reverse voltage. Usually diodes have been used as a crowbar switch, but it is not a practical system because the cost of the diodes goes up enormously with increasing the system voltage and current. This paper presents a novel protection scheme of a charging and discharging system of a 300 kJ capacitor bank using a low-cost crowbar system which consists of a crowbar switch and resistors. Triggered vacuum switch(TVS) was used for a crowbar switch, and Rogowski coil was used to determine a trigger time of TVS. When this crowbar system is applied to our pulsed power system which consists of capacitor bank($123muF$), inductor() for forming a pulse, load resistor$(100 m\Omega)$, and a closing switch, instantaneous reversal voltage of capacitor bank could be limited less than 1.8 ㎸ until capacitor bank was charred to 17 ㎸.

Sensor fault detection and isolation problems subject to H_/$H_{\infty}$, performance are concerned for linear time-invariant systems with time delay in a state and parametric uncertainties. To that end, a model-based observer bank approach is pursued. The design conditions for both continuous- and discrete-time cases are formulated in terms of matrix inequalities, which are then converted to the problems solvable via an algorithm involving convex optimization.
