There is a trade-off between read stability and writability under a full-/half-select condition in static random access memory (SRAM). Another trade-off in the minimum operating voltage between the read and write operation also exists. A new peripheral circuit for SRAM arrays, called a variation sensor, is demonstrated here to balance the read/write margins (i.e., to optimize the read/write trade-off) as well as to lower the minimum operation voltage for both read and write operations. A test chip is fabricated using an industrial 45-nm bulk complementary metal oxide semiconductor (CMOS) process to demonstrate the operation of the variation sensor. With the variation sensor, the word-line voltage is optimized to minimize the trade-off between read stability and writability ($V_{WL,OPT}=1.055V$) as well as to lower the minimum operating voltage for the read and write operations simultaneously ($V_{MIN,READ}=0.58V$, $V_{MIN,WRITE}=0.82V$ for supply voltage $(V_{DD})=1.1V$).

The rapid development of internet information technology has increased interest in e-Trade these days, but it is not activated greatly up to now. In order to promote e-Trade, it is essential to construct cooperative process such as connecting systems among trade related parties. Building e-Trade platform which is based on the infrastructure of the past trade automatic system is key point of promoting e-Trade. To do this, a study on the basic concept and specific components of e-Trade platform is needed absolutely. At this point of view, after this paper has examined domestic and foreign studies on the fundamental technologies about electronic commerce, it drew several key technologies that could be applied to e-Trade considering the current IT trend. Then it evaluates these technologies according to Technology Reference Model(TRM) of the National Computerization Agency. This will help us to show the operation strategy as well as the concept of future e-Trade platform and its composition. On the basis of the theoretical background, this paper classified NCA's technology model into 6 fields, which are application. data, platform, communication, security and management. Considering the key technologies, e-Trade platform has to be mutually connected and accept international standards such as XML. In the aspect of business side, trade relative agencies' business process as well as trading company's process has to be considered. Therefore, e-Trade platform can be classified into 3 parts which are service, infrastructure and connection. Infrastructure part is compared of circulating and managing system of electronic document, interface and service framework. Connecting service (application service) and additional service (application service) consist of service part. Connecting part is a linking mutual parts and can be divided into B2B service and B20 service. The organization operating this e-trade platform must have few responsibilities and requirements. It needs to positively accept existing infrastructure of trade automatic system and improving the system to complete e-trade platform. It also have to continuously develop new services and possess ability to operate the system for providing proper services to demanders. As a result, private sector that can play a role as TTP(Third Trust Party) is adequate for operating the system. In this case, revising law is necessary to support the responsibility and requirement of private sector.

최근 자유무역지역은 물류 기능에 생산 기능을 적절히 보완하는 복합형을 지향하는 것이 일반적이다. 그럼에도 불구하고 광양만권 자유무역지역은 전통적인 물류 기능에만 집중되어 생산 기능 도입을 통한 부가가치 창출은 미흡한 수준에 있다. 따라서 자유무역지역을 지역 및 국가 발전의 성장 동력으로 활용하기 위한 기능 강화 방안이 제시되어야 한다. 기능 강화를 위해서는 생산 기능 도입을 통합 복합형 자유 무역지역 지향과 관리 운영상의 효율화 방안이 필요한 것으로 분석된다. 주요 연구 결과를 요약하면 다음과 같다. 첫째, 단기적으로는 기존에 자유무역지역으로 지정되어 있는 서측 배후단지의 일부를 활용하여 생산 기능을 강화하고, 중장기적으로는 자유무역지역의 확대 지정을 통한 생산 기능의 강화가 필요하다. 둘째, 효율적인 관리 운영을 위해 단기적으로는 자유무역지역 간의 협력체계를 구축하는 것이 필요하며, 중장기적으로는 자유무역지역 간의 중복된 기능을 단일화하고 통합 관리하는 정책적 방안이 필요하다.

In order to implement e-trade infrastructure through the radical innovation of trade process, e-trade platform which is called 'uTradehub' has been developed for three years. After pilot operation of this platform in 2007, the formal service of e-trade such as logistics, customs and foreign exchanges had been provided in 2008. However, the usage of e-Trade platform is not the level of users' satisfaction because trade-related communities have not actively participated into e-trade platform and several functions with users requirements are necessary to develop additionally. In this regard, there are strong demands to suggest some strategies for application and usage proliferation of e-trade platform. Therefore, this paper would like to evaluate the current status of e-trade platform service and usage by the theoretical consideration of preceding researches and practical analysis of statistical data. Then, it will explore several service improvement ideas in terms of system supplementation and integration, electronic documents standardization, radical change of using fee, global connection, user oriented education and advertisement.

본 연구는 최근 정체기에 접어들었다고 볼 수 있는 전자무역 연구에 조금이라도 도움이 되기 위해 기획되고 연구되었다. 무엇보다 본 연구의 배경은 외국에서의 전자무역에 관한 선행문헌과 국내에서의 전자무역에 관한 선행문헌이 서로 다르다는 것에서 출발한다. 외국에서의 전자무역 연구 동향은 주로 통관 업무에 국한되어 연구가 진행되는 경우가 많았지만 국내에서의 전자무역 연구 동향은 주로 대금결제와 선하증권의 전자화 등 대금결제의 전자화 및 전자신용장의 구축을 중심으로 이루어져 왔다. 이와 같은 차이점이 실제 전자무역 구축에도 그대로 이어져 외국에서의 전자무역 구축 동향과 국내에서의 전자무역 구축 동향이 서로 다소 다르게 이루어졌다. 미국을 중심으로 한 선진국에서는 통관 및 물류 영역을 중심으로 전자무역이 구축되었고 우리나라에서는 통관 영역의 전자화도 이루어졌지만 신용장을 포함한 결제 영역에서도 전자화도 구축되었다. 이에 본 연구에서는 최근에 논의되고 있는 글로벌 전자무역 동향을 비교적 심도 있게 분석하였으며 한국의 전자무역 추진의 핵심 당사자인 한국무역정보통신과 관세청이 구현한 우리나라 전자무역 현황을 알아보고 검토하였다. 이를 바탕으로 한국 전자무역 추진상의 여러 문제점을 도출하였고 이에 대한 해결방안을 제시하였다. 논의 결과, 우리나라 전자무역 구축은 향후 전자신용장 등 대금결제의 전자화 보다는 통관, 물류 영역의 전자화가 더욱 필요하다고 분석되었다.

It is no unnecessary to tell the importance of foreign trade in Korea economics. Nevertheless, government's direct support is impossible owing to WTO's regulation. Accordingly, government have brought focus into trade facilitation as paperless trade. e-Trade document repositary building by government's budget and private sector's cooperation is a part of e-Trade platform and necessary function in connection with relay and certification of e-Trade document. This study examined the estimated operational problems of e-Trade document repositary as compared Licensed Electronic Document Repositary. Firstly, the operator of e-Trade document repositary undertake multiple role and function as Licensed Certification Authorities(e-sign Act), Licensed Electronic Document Repositary(Framework Act on Electronic Transaction) etc. Secondly, sufficient levy that meet operating cost of the e-trade document is the key point of e-Trade document repositary's success, because additional budget invest in that operation is too hard to do. Thirdly, the operator of the e-Trade document repositary have to keep fairness, objectivity and transparency because the operational right is exclusive.

This paper is to propose the Direction for the institutional improvement of Financial Supply Chain Management(FSCM) Solution which are currently coming into operation under Global e-Trading Platform. The Financial Supply Chain compromise the entire trade processes and information that manage a trader's cash, Accounts payable and receivable, Risk, working capital, and so on in international trade transaction. From a buyer's perspective, this involves the full procurement-to-payment process. For the seller, it is the order-to-cash cycle. Bolero provides the party concerned a e-trade platform which conformed to these fundamental pre-requisites to underpin fully electronic trade. But this FSCM solution have failed to provide the efficient platform to effectively manage the process of Global e-Trade because it does not correspond with e-Trade environment. Therefore, present FSCM system need the institutional improvement as follows: AA) Strengthening the role of the correspondent Bank under e-Trade System, BB) Extending the function of e-Trade intermediary institution, CC) The introduction of Trade Insurance System, etc. So, by streamlining and automating these processes on an open and flexible platform, The party concerned can optimize their trade transaction and maintain better relations with their business partners
