A counter-guarantee is an independent undertaking and it functions in the same way as an ordinary independent guarantee. However, the typical notion of independence which applies to the relationship between the guarantee and the underlying contract cannot be exactly transposed to the relationship between the counter-guarantee and the primary guarantee, because the primary guarantor bears its duties that derive from the mandate. In this respect, this study reviews, with some critics, a Korean appellate court's decision and argues that, in spite of the principle of independence between the counter-guarantee and the primary guarantee, the primary guarantor may not be entitled to reimbursement from the counter-guarantor, if it is objectively evident that the primary guarantor has failed to perform its duty of verifying compliance under the primary guarantor or if it is objectively evident that the primary guarantor knows that it is objectively evident that there was fraudulent calling by the beneficiary under the primary guarantee.

Quality assurance (QA) for nuclear R&D project is very concerned about the poor economy due to the improper selection of QA requirements. This paper proposes a new methodology for determining the relative importance weights of QA requirements considering the attributes of nuclear R&D project. QFD (Quality Function Deployment) is used as a conceptual framework and fuzzy number is introduced to capture the vagueness uncertainty existing in human judgement. Also we use a confidence attitude of decision-maker in order to improve the reliability of extracted attribute level of R&D project. Case study on a nuclear R&D project and scenario analysis are carried out to verify the usefulness and effectiveness of proposed methodology.

The B2B e-commerce assurance system supports e-commerce purchases by Credit Guarantee Fund. This process seeks to replace a variety of current systems, including B2C, the credit card payment method on B2B, 2001 Credit Guarantee Fund and the Bank, logistics, e-MP (Market Place), and Business-to-business e-MP (business-to-business electronic payment settlement system). Over the past 10 years of its operation, the e-MP service (B2B e-commerce electronic payment systems) has contributed much to the growth of SMEs. The development of business-to-business e-commerce transactions systems and limits have provided a stable purchasing platform, improving corporate competitiveness. However. the project-based scale of credit guarantee institutions has limitations. To overcome these limitations, we propose a new model of direct or indirect government support for small business e-MP projects. This new model will support the B2B electronic commerce by allowing it to directly involve guarantee institutions directly in B2B online transactions. Therefore, this study urges government backing of the SME based B2B online business model with e-MP service.

하반기부터 국가가 시행하는 추정가격 78억원 미만(지자체 235억원미만)의 국내입찰대상 모든 공사는 인터넷을 통한 전자입찰로 낙찰자가 선정된다. 또 건설업 등록시 법정자본금에 해당하는 보증능력 확인서를 제출해야하고 일정기준 이상의 사무실을 갖춰야하는 등 건설업등록요건이 강화된다. 이와 함께 고급주택을 제외한 신축주택에 대한 양도소득세가 2003년 6월말까지 면제되며 부동산투자 회사가 설립돼 본격적으로 부동산에 대한 간접투자시대가 열린다. 정부는 2001년 7월 1일 부터 달라지는 부처별 경제$\cdot$행정제도를 종합 정리해 발표했다.

오늘날 항공기 설계와 제작은 다국적인 산업의 형태로 이루어지고 있다. 즉 항공기 서브시스템은 세계 각국에서 독립적으로 설계, 제작 및 시험한 후 한 곳으로 납품되어 조립 제작되는 데 이 때 중요한 것이 표준화이다. 항공전자장비의 낙뢰 간접영향에 대한 인증의 경우 RTCA DO-160E, Section 22 Lightning Induced Transient Susceptibility(낙뢰 유도 과도현상 적응성)로 표준화 되어 있다. 이 Section 22는 낙뢰 간접영향에 대한 항공전자장비 단위 즉, LRU (Line Replaceable Units)와 같은 부품단위의 시험 요건을 규정하고 있으며 이 규격은 현재 전 세계적으로 통용이 되고 있다. 1980년대 초 상용 수송기에 디지털 "Fly by Wire" 비행 시스템과 엔진제어시스템(EEC, Electronic Engine Control)의 도입 이후, 항공기 시스템이 낙뢰 환경에서 운용시 신뢰성을 보증할 필요성이 대두되었다. 데이터 처리를 통하여 제어되는 각종 항공전자장비에는 다중타격(MS)과 다중파열(MB) 기법에 의한 시험 사항이 최근 추가 되었다. 실제 낙뢰 환경과 유사한 시험실 모사를 위해 계속적인 연구가 진행 중이며 신규 시험 규격서가 새로이 출간되고 있다.

The learning control develops controllers that learn to improve their performance at executing a given task, based on experience performing this specific task. In a previous work the authors presented an iterative precision of linear decentralized learning control based on p-integrated teaming method for the vertical dynamic multiple systems. This paper develops an indirect decentralized learning control based on adaptive control method. The original motivation of the loaming control field was learning in robots doing repetitive tasks such as on a]1 assembly line. This paper starts with decentralized discrete time systems, and progresses to the robot application, modeling the robot as a time varying linear system in the neighborhood of the nominal trajectory, and using the usual robot controllers that are decentralized, treating each link as if it is independent of any coupling with other links. Error wave propagation method will show up in the numerical simulation for five-bar linkage as a vertical dynamic robot. The methods of learning system are shown up for the iterative precision of each link at each time step in repetition domain. Those can be helped to apply to the vertical multiple dynamic systems for precision quality assurance in the industrial robots and medical equipments.

국민소득의 증대와 함께 소비자의 고품질 농축산물에 대한 수요와 관심이 날로 증가하고 있다 이에 따라 안전하며 고품질인 농축산물을 소비자에게 공급하기 위하여 안전한 농축산물의 생산, 신선도 유지를 위한 유통구조의 개혁, 품질 및 안전성 평가기술개발을 위한 노력이 보다 더 요구되고 있다. 소비자가 믿고 구매하기 위해서는 농축산물에 대한 품질보증이 필수적이며 이를 위해서는 신속하고 정확한 품질 및 유해물질의 판정기술 개발이 필요하다. 많은 농축산물에 있어서 주요 품질인자인 숙도 및 신선도의 변화는 휘발성 화학물질로 이루어진 냄새의 변화로 나타나므로 이를 측정하여 품질 및 안전성을 간접적으로 판정할 수 있다 기존의 냄새에 의한 품질 판정은 판별전문가에 의한 관능평가법 또는 GC(Gas Chromatography)나 GC/MS(Gas chromatograph mass spectrometer)에 의하여 주로 이루어져 왔다. 하지만, 관능평가법의 경우 판별전문가의 개인적인 차이, 피로, 건강상태 등에 따라 판정의 객관성이 떨어질 우려가 있고, GC나 GC/MS를 이용할 경우 냄새분석에 많은 시간과 노력이 소요되는 문제점이 있다.

The financial resources for public land banking enacted by Public Land Banking Act (2009) are LH (Korea Land and Housing Corporation) contributions, LH Bond, Land Bank revenues, etc. But, in real, the efficient funding resource is mainly LH bond. In these days, LH has experienced deep financial distress, and difficulties in issuing it's bond. Therefore, Land Banking project also has been inactivated because of poor financial resources. As Land Banking project depending its financial resources mainly on LH Bond does not have financial sustainability, it is necessary to reform the fundamental funding structure. This is the starting point for the topic of this paper. This paper suggests to reform the funding structure, and to introduce Land Bank Bond guaranteed by Government, and also to modify the accounting method of Land Bank to separate the Land Bank accounts with LH accounts. The funding structure reform can be summarized as follows; In early stage of the Land Banking project, sufficient government support by guaranteeing the Land Bank Bond is necessary. Gradually, the portion of LH's contribution can be increased in company with LH's financial distress being solved and administration being normalized. When the project reached on the stage of maturity, cash inflows by selling the reserved land can exceed the cash outflows for reserve new land. To introduce the Land Bank Bond guaranteed by government, the Public Land Banking Act (2009) should be revised. Along with this, to modify the accounting method of Land Bank, the rule for public enterprise accounting system must be partially revised.

This study compares and analyzes the efficiency of R&D activities of technology-innovative small and medium-sized enterprises(SMEs) between industries and proposes ways to improve efficiency. The research samples are 6,708 technology-innovative SMEs, which have received a guarantee by the KIBO from 2008 to 2011. Input variables are the level of R&D personnel, R&D investment, and output variables are patent applications, prototype. Efficiency is measured by the DEA model, and indirect comparisons that are individually measured by industry are performed. As a result of the analysis, the CCR for determining the optimal returns to scale is 0.19, the BCC for determining the optimal input distribution is 0.70, and the SE for determining the optimal output is 0.30. By industry type, the medium and low-tech industries have high CCR and BCC, while the high-end and high-tech industries have high SE. R&D activities need to be operated on an optimal scale through managing R&D performance because there is the inefficiency of scale across the industry. The contribution of the study is to analyze the R&D efficiency of each industry of technology-innovative SMEs by the technology evaluation data of the KIBO.
