Coarse-Grained Reconfigurable Architecture (CGRA) is a very promising platform that provides fast turn-around-time as well as very high energy efficiency for multimedia applications. One of the problems with CGRAs, however, is application mapping, which currently does not scale well with geometrically increasing numbers of cores. To mitigate the scalability problem, this paper discusses how to use the SIMD (Single Instruction Multiple Data) paradigm for CGRAs. While the idea of SIMD is not new, SIMD can complicate the mapping problem by adding an additional dimension of iteration mapping to the already complex problem of operation and data mapping, which are all interdependent, and can thus significantly affect performance through memory bank conflicts. In this paper, based on a new architecture called SIMD reconfigurable architecture, which allows SIMD execution at multiple levels of granularity, we present how to minimize bank conflicts considering all three related sub-problems, for various RA organizations. We also present data tiling and evaluate a conflict-free scheduling algorithm as a way to eliminate bank conflicts for a certain class of mapping problem.

This paper reviewed "unconscionability" as an exception to the independence principle of bank guarantees. Apart from fraud which has been recognized in most international jurisdictions, Uuconscionability would also be recognized as the exception to the legal principle, the so-called "fraud rule" or "an abuse of rights." Unconscionability exception is applied in the same manner as fraud and other exceptions to the principle of independence. The exception should allow guarantor to dishonor the drawings that abuse the independence principle. However, outright or manifest facts of the unconscionability must be established in order to apply the exception. Lots of arguments or conflicts may be caused in applying the unconscionability exception. Therefore, this study aims to prevent institutional abuses or to reduce the disputes from setting up the legitimate scope and standard for application of the exception by reviewing these procedural issues and problems under bank guarantee transactions. This paper also suggested practical implications and countermeasures for the institutional application.

The utilization of GPUs on general-purpose computers is currently on the rise due to the increase in its programmability and performance requirements. The utility of tools like NVIDIA's CUDA have been designed to allow programmers to code algorithms by using C-like language for the execution process on the graphics processing units GPU. Unfortunately, many of the performance and correctness bugs will happen on parallel programs. The CUDA tool support for the parallel programs has not yet been actualized. The use of a dynamic analyzer to find performance and correctness bugs in CUDA programs facilitates the execution of sophisticated processes, especially in modern computing requirements. Any race conditions bug it will impact of program correctness and the share memory bank conflicts to improve the overall performance. The technique instruments the programs in a way that promotes accessibility of the memory locations accessed by different threads well as to check for any bugs in the code of a program. The instrumented source code will be used initiated directly in the device emulation code of CUDA to send report for the user about all errors. The current degree of automation helps programmers solve subtle bugs in highly complex programs or programs that cannot be analyzed manually.

전 세계적으로 물부족 사태는 매우 심각한 상황에 이르렀다. 우리나라도 예외는 아니어서 용수부족이 예상된다. 지하수는 이러한 문제를 일부 지역에서 해결해 주는 역할을 할 수 있으며, 특히 강변여과는 위치와 규모의 제약에도 불구하고 저수지들이 지니고 있는 문제점들을 극복할 수 있다고 알려져 있다. 강변여과 적지분석을 위해 댐건설 지연과 물부족을 겪고 있는 네 지역을 선정하여, 갈등을 해결하고 대안의 우선순위를 결정하는 분석도구인 계층분석과정 (AHP)을 적용하였다. 또한 AHP를 이용한 분석결과를 기존 연구와 비교하였다. 개발된 강변여과 적지분석 방법론은 합리적 의사결정을 위한 판단근거를 제공할 것으로 사료된다.

재벌의 은행소유를 반대하는 논거로서 흔히 제시되는 두 가지 이유, 즉 1) 은행이 재벌의 사금고가 될 우려가 있다거나, 2) 산업자본과 은행자본이 결합할 경우 이해상충관계를 악용할 가능성이 있다는 등의 이유는 정상적인 경우 성립하기 힘들다. 이 같은 우려는 이자율규제, 은행채무에 대한 정부의 명시적 암묵적 보증 등 은행에 대한 인위적 규제나 보호에 기인하는 것으로서 은행의 소유주가 누구인가와는 무관한 사항이다. 또한 이 같은 인위적 규제와 보호는 그것 자체가 은행산업의 심각한 파행과 위기를 반복적으로 초래하는 왜곡된 인센티브를 제공하고 있으므로 제거되지 않으면 안 된다. 왜곡된 인센티브 구조가 바로 잡힌다면 은행을 누가 소유해야 하는가의 문제는 무의미한 질문이 되고 말 것이다.

L/C provides the exporter and the importer with safe assurance in the exchange of goods for payment in international trade. It involves a number of parties. Although the parties may have confidence in their client, bad faith or ignorance of international banking practice by any of these parties could cause the failure of transaction, which makes international trade a risky business. Most of the risks are found in transport document, which can cause disputes. There are many factors in the risk of transport documents under L/C transaction. One most common risk factor for the beneficiary in all transport documents is even if there is no discrepancy in document, the issuing bank or the applicant refuses to pay or delay payment insisting there is a discrepancy. In some very rare cases, the beneficiary may not get paid due to unfair injunction of the local court of the applicant. For the applicant, most common risk factors are fake bill and fraud. Risks classified according to the sorts of transport documents are as follows. 1. In B/L, payment can be refused because it is regarded as charter party B/L, although there is no real charter party contract. And the applicant can bear the potential risk of the loss or deterioration of cargo through transhipment of the cargo loaded on board in container if transhipment is prohibited without excluding of UCP 600 article 20 (c). 2. In charter party B/L, the applicant may take delivery without paying when charter party B/L is signed by charterer, which can result in a big loss for the beneficiary and the negotiating bank. And risks may arise when cargo is seized because the charterer does not pay the hire. The applicant and the issuing bank are also vulnerable to a risk - Against whom should they file a suit when cargo gets damaged during transportation? 3. In multimodal transport document, which is subject to a conflict because there is a big difference in viewpoints between transport industry and banks, conflicts may also arise when L/C requires ocean B/L and accepts multimodal transport document at the same time, but does not specify the details. 4. In air waybill, where the consignee is not the issuing bank but the applicant, risks may take place to the beneficiary when the applicant takes delivery but refuses to pay asserting minor discrepancies in document. The applicant may also bear the risk when cargo may not be loaded because air waybill is a received bill. Another risk may arise when although the applicant prohibits transhipment without excluding UCP 600 article 23 (c), the cargo may be transhipped, provided that the entire carriage is covered by one and the same air waybill.

The Republic of Korea navy challenged from the unexpected surprise attacks by the North Korea navy, albeit, the developments of up-to-date naval forces' technology, and the ceaseless efforts for war preparedness. My study divided into two categories. Qualitative methods used for literature review of international relations theory related to the war onset and for investigating events occurred on the Peninsula and its surrounding seas from 1968 to 2007. Quantitative method used such as the analyses of national power index of the two Koreas, the United States, and China, the uses of equation model to calculate power index of alliance, COPDAB(Conflict and Peace Data Bank) index analysis. Like Choi's study on East Asia maritime conflict, as a conclusion, considering both AT theory and maritime national power as a tool for predicting maritime conflict in the Peninsula proved significant. Based on the study, ROK navy need to prepare for the maritime conflict because the results showed North Korea would initiate maritime disputes sooner or later using fatal asymmetric forces and methods. As a policy suggestion, we are required to maintain a concrete ROK-US alliance ties and to construct naval forces due to the deterring functions of maritime national power.

에스컬레이션 조항의 목적은 외부가격 메카니즘에 따라 신용장금액을 증가시키기 위한 것이다. 이것은 금속이나 석유제품거래에서 발견된다. 신용장의 에스컬레이션 조항은 그 조항이 실행 가능한 것으로 신용장을 구성하느냐 여부에 대한 의문을 야기시킨다. 신용장 이외의 근거에 대한 참조는 신용장을 신용장 이외의 다른 약정에 구속시키는 비 서류적 조건이라는 것이다. 그러나 객관적이고, 쉽게 얻을 수 있는 지표에 대한 참조는 신용장 약정을 모호하게 하는 것이 아니고, 객관적 자료로 입증할 수 있다는 점에서 비서류적 조건이 아니다. 가능한 해결책은 UCP에서 신용장의 비서류적 조건 중 일부를 유효한 것으로 인정하는 것이다. 예컨대 신용장에 언급된 지표는 UCP가 적용되는 신용장거래에서도 ISP98이나 URDG75에 규정된 것처럼 무시하지 않는 것이다. 비서류적 조건이 "중심적이고 기초적"인 것이라면, 그것은 당사자가 비독립적인 지급약정을 할 의도가 있은 것으로 보인다. 당사자 간의 갈등을 극복하는 가장 공통적인 수단은 에스컬레이션 조항이 포함된 신용장을 발행하되, 개설은행의 최대지급약정의 한도를 설정하는 것이다.

The purpose of this study is to explore business investment and operation of O2O (Online-To-Offline) combined service. The study will analyze the necessary factors for growing the business by dividing the O2O service by industry. The Online-to-Offline is a method of inducing purchases of products and services by connecting between online and offline This research methodology organized the four stages of the analysis process. The analysis of all stages was performed with association rules in big data techniques. It is divided into the start-up period, growth period, maturity period, and decline period, and analysis is conducted on the business investment, expenditure cost, business operation, and conflict factors. As the research result, the first analysis has shown commonality with government subsidies, bank loans, and personal funds in all industries. The second analysis showed a lot of expenditure on labor costs of internal employees, marketing/sales, facility facilities, equipment, and equipment purchase costs. The third analysis showed difficulty in raising the investment resources necessary for business operations in all industries. The last analysis showed conflicts in the industry, businesses license, legal systems, and small business owners in all industries. This study contributed to the abundance and diversity of research methodologies in management information systems using association rules. In addition, the description of organizational development theory was updated while explaining the business investment and operation of O2O combined services. In practical implication, the O2O services include environmental factors that cause convergence between industries. Accordingly, this is required for new O2O services through new laws and systems and reorganization of existing laws and regulations.
