This study analyzes trade communication methods by comparing and analyzing payment methods and procedures of L/C and BPO transactions. As a result of the study, BPO transaction is validated based on the combination results of the confirmed baseline and data set unlike the L/C transaction. Therefore, BPO is superior to L/C transaction in that there is no confrontation between the parties over the matching results. And it can proceed with certain transaction that is paid first and proved later. In addition, the process of accepting data mismatches results in a confirmation of the payment commitment considering the intention of the importer. This allows flexible disposition of documents in response to the post payment situation as long as the documents are held by the exporter, which can be said to be superior to the L/C transaction.

본 연구는 교통선진국에서 활발한 연구 및 개발 등을 거쳐 일반화 작업 등이 시행되고 있으며 국내에서도 경찰청과 도로교통공단이 함께 도입을 추진하고 있는 도시교통정보시스템(UTIS : Urban Traffic Information System, 무선교통정보수집제공시스템으로 더 잘 알려짐)을 소개하고, 추후 UTIS 도입 시, 서비스 이용 수요 예측과 실제 소비자인 운전자가 지불 방식별로 만족할 수 있는 적정 이용료에 대하여 연구하였다. 본 연구에서 얻어진 결과를 요약하면, 다음과 같다. 첫째 UTIS 서비스 이용 수요 예측 모델을 이항 로짓 모델을 통해 구축하였다. 둘째 UTIS 서비스의 이용료 지불 방식별 이용 행태 예측 모델을 순서형 프로빗 모델을 통해 구축하였다. 셋째, UTIS서비스의 이용 행태별 지불 방식별 선호도를 파악한 뒤, 이용료 지불 방식별로 민감도 분석을 통하여, 이용률의 단위 탄력점을 파악하고, 이용자 측면이 고려된 각 지불 방식별 적정 이용료를 서비스 공급자에게 제시하였다.

Purpose: The scale of a market of mobile payment which was insignificant is explosively being improved by development of various communications technology and achieving rapid diffusion of smart phone. According to this phenomenon, new method of financial dealings through a mobile can be seen as a new paradigm that leads to a change of existing payment work and also recognized as an innovation of information technology. Methods: but a study regarding whether the use of mobile payment service takes an important role as an influencial factor is still insufficient. This study was based on the model of innovation resistance by Ram(1987) and established a hypothesis and a model to confirm how four factors (usability, security, economic feasibility, responsiveness) influence to innovation resistance and the intention of discontinuous use. Results: usability, security were found to be significant predictor variables of innovation resistance to use mobile payment system, but economic feasibility, responsiveness were not found to be significant predictor variables. Conclusion: Providing gave a theoretical foundation for future research in that it presents the variables to consider new forms of mobile payment services, the mobile payment services will need to show a differentiated strategy and traditional marketing strategy.

Purpose: The purpose of this study is how Chinese users' personal traits affect the intention to use mobile payment. This research selects personal innovativeness and habit of cash payment as personal traits, and considers perceived risks and relative advantage as personal beliefs. In addition, the research divided perceived risks into three multi-faceted risks, which are privacy risk, financial risk and performance risk. Methods: The method of this study used questionnaire survey to collect 241 data on users' perception on mobile payment, and also used a structural equation modeling method. Results: The result of this paper shows that all hypotheses are statistically significant except 4 hypotheses. Conclusion: The result of this study found that personal innovativeness is negatively related with all 3 kinds of perceived risks as anticipated. And Chinese users' traditional habit of cash payment negatively affects intention to use mobile payment but is not statistically significant affecting three perceived risks. Among perceived risks, privacy risk is the most negatively influencing factor to relative advantage.

본 논문에서는 SW감정에서 많이 사용되는 완성도와 기성고의 용어의 정의를 재조명하고, 최근 SW분쟁에서 요구하는 완성도와 기성고의 의미와 산출 방법을 제시한다. 일반적으로 SW감정에서의 완성도는 최종 구축/구현된 SW의 기능상의 완성된 정도를 의미하고 있으며, 기성고는 개발비를 정산하기 위하여 현재까지 완료된 산출물 또는 기능을 기반으로 비용을 산출하는 것을 의미한다. 따라서 완성도는 최종적으로 개발 완료된 제품/산출물의 기능이나 인터페이스를 기준으로 판단하며, 기성고는 SW개발 단계별로 산출물 및 투입된 비용으로 산출된다. 최근에는 SW감정이 복잡해지고 완성도와 기성고에 대한 요구사항이 구체적으로 변화되고 있으므로, 본 논문에서는 각 용어의 의미와 목적을 다시 살펴보고 그 산출 방법을 제시한다.

전통적인 상거래 방식에서의 결제시스템으로는 신용장에 의한 방식, 추심에 의한 방식, 송금에 의한 방식 등이 있으며, 신용장방식은 수출자가 대금지급에 대한 확실성과 금융상의 편리, 신용위험의 감소로 보편적으로 가장 많이 선호하고 있다. 추심 방식은 오랜 신용관계에 있는 거래선간에 조심스럽게 이용되고 있다. 송금방식은 소액이나 견본 등의 대금지불에 알맞은 방식이다. 인터넷 전자상거래 방식에서의 결제시스템으로는 지불 브로크형 시스템, 전자화폐시스템, 소액전자지불시스템, 전자자금이체시스템 등이 있다. 본 논문에서는 전통적인 방식의 결제방식과 인터넷을 이용한 결제시스템의 차이와 장ㆍ단점을 비교하였다. 인터넷 결제시스템은 전통적인 방식보다 결제시간을 줄일 수 있는 반면, 소매거래 (B to C)환경에 국한되는 단점을 가지고 있다. 도매거래(B to B)하에서는 전통적인 결제시스템이 안정성, 안전성, 신뢰성 측면에서 인터넷 결제시스템보다 아직까지는 월등한 상황이다.

본 논문에서는 현재 국내 ETCS(Electrical Toll Collection System)에 적용될 예정에 있는 후불식 지불 방식에 있어서 수행해야할 전자 신용카드(EMV) 처리절차를 제안한다. 현재 국내에서는 한국도로공사의 하이패스, 터치패스 시스템이 비접촉식 ETCS로 운영되고 있으며, 현재의 운영 방식은 일종의 전자화폐 개념의 선불(pre-paid)식이다. 이에 반해 후불(credit)식은 신용카드 기반의 지불을 수행함으로써 미리 지불할 필요가 없다는 장점이 있다. 현재 국내의 ETCS에 후불식의 도입이 준비 중에 있으며, 본 논문에서는 이러한 후불식 지불에서 고려해야 할 EMV 처리 방식을 제안한다.

This study aims to derive practical suggestions to apply application methods by auxiliary costs, especially application of logistics and customs clearance areas in order to establish EPS support system of auxiliary cost occurred from export/import. For the propose, this study has analyzed types and situation of auxiliary costs, application method by auxiliary costs, payment situation of logistics auxiliary costs and clearance auxiliary costs and suggested the relevant problems and their application methods. Especially, in case of logistics auxiliary costs through connection to the attached general documents required for negotiation by reflecting characteristics of B2B transactions. In addition, it has suggested that those services by the said system should be conveniently used commonly by the export companies and logistics companies through provision of various payment measures, support of foreign currency payment, etc. and security of reliability/system stability, etc. for the compatible payment with other systems as the prerequisite for the successful settlement of the auxiliary costs EPS. It is expected that satisfaction of the uTradeHub users such as export/import companies and logistics companies will be increased, user-oriented customized information services such as raw cost prediction service through calculation of auxiliary costs could be available in the future and efficiency of work processes related to auxiliary costs will be increased, by providing the EPS through various single window based payment measures through establishment of the export/import auxiliary costs payment system.

Globally, Fintech, which acts to replace existing intranational payment methods, is actively used, and such Fintech payments are widely accepted in international B2C trade. However, Fintech for B2B trade has not been released to the market thus far, and previous attempts at electronic international payment systems, such as Bolero, TradeCard, and Identrus, have not succeeded, and most of them have completely disappeared. On the other hand, there are continuing attempts to introduce Fintech technologies such as blockchain to international payments, and these attempts are more widely pursued in foreign countries. If international payments using Fintech are marketed through foreign services and such Fintech services become the de-facto standard for international payments, then Korea in which dependency on international trade is high will be vulnerable due to a dependency on foreign services such as relying on foreign SNS platforms like Facebook and Instagram. Therefore, this paper proposes a business model that can be used as a legitimate B2B trade international payment system on the basis of domestically provided services, focusing on various services afforded by K-SURE, which is the Korea Trade Insurance Corporation.

Biometric authentication for account-based mobile payment continues to gain attention because of improvements on sensors that can collect biometric information. We propose an enhanced method for mobile payment security based on biometric authentication. In this mobile payment system, the communication between the user and the relying party is based on public key infrastructure. This method secures both the key and the biometric template in the user side using fuzzy vault biometric cryptosystems, which is based on non-random chaff point generator. In this paper, we consider an important process for the common fuzzy vault system, that is, the feature extraction method. We evaluate various feature extraction methods to enhance the accurate performance of the system.
