기존의 명함 관리는 저장된 연락처 정보가 변경되었을 때 사용자가 수동으로 정보를 변경해야 했고, 표준화 되지 않는 항목으로 인해 여러 응용사이에 정보의 교환이 원활하지 않았다. 이러한 불편함을 해소하기 위해서 원활하게 명함을 상호교환 할 수 있는 전자명함의 개념을 도입하여 항상 최신의 정보를 유지할 수 있는 시스템이 필요하였다. 본 논문은 현재 차세대 웹 기술로 각광받고 있는 시맨틱웹 기반 기술인 RDF와 전자명함의 표준으로 자리 잡은 IMC에서 제공하는 vCard를 이용하여 'e-명함'의 개념을 설계하였고, 기존의 단순한 상호교환용 파일역할만 했던 vCard의 개념과 달리 개인의 고유한 URI를 가질 수 있게 하여 하나의 DB 또는 사이트 내에서만 연락처 정보가 관리되지 않고 표준화된 정보를 통해 보다 정확하고 신속한 관리기능을 갖춘 'e-명함' 시스템을 개발하였다.

This paper is presented to study simplification of face image using cubic spline interpolation for a business card with 2D barcode. People often forget business card's owner because business cards don't be included a face picture generally. To solve such problem, many applications have be developed through mobile devices, Internet and so on. But they couldn't caught up with value of existing business card mad by paper. Hence, some methods which can put information on business card using 1D or 2D barcode had suggested. but they couldn't include information like face image or company logo image which have too much data. Therefore, we study the simplification method of face image to encode from a face image to 2D barcode. The simplification method using spline curves defined by feature points which we dotted on face, ears, hair, eyebrows, nose, lips, neck, etc.. on a face area. for experiment, we see real face image and simplified face image made by proposed method after we automatically extract face watch through camera. In experimental results, data of simplified face image was reduced as small as it can be expressed by 2D barcode, and confirmed that it can effectively express features.

Recently, personal business styles have been rapidly changed into e-business due to the rapid progress and deployment of Internet. As a result of the change, new and safe ways of payment such as electronic wallet, electronic money and electronic check have been developed and introduced. In this paper a secure and user-friendly payment method is addressed. One of most important reasons why newly developed safe payment methods are not widely used in e-business is lack of convenience for the users. On the other hand credit card based payment, which is traditional one, is the most prevailing due to the user-friendliness. However this payment also has some problem in sense of security. In this paper, we design and implement a secure credit card-based payment system using one-time credit information. The main features are "payment information must be new", "can use the old credit system", and "do not require client software".

The research aims to help merchant acquiring institutions gain a better insight on what merchant establishments in the Singapore market perceive of the costs they incur due to credit card acceptance. The research attempts to study the Singapore market and establish if increased credit card usage does increase costs for the merchant establishments that accept credit cards, this will help to acquire institutions in Singapore have a better understanding of merchant perceptions and what drives or deters credit card acceptance in the Singapore market. The survey was based on an interview of merchant establishments and the views of the merchants and was not based on their financial data. As a first step, the variables used in the survey were tested for interdependence using Chi-square tests; subsequently data reduction using factor analysis was performed and finally linear regression to establish a relation between dependent and independent variables. Merchant establishment believe accepting credit cards and increasing volume is costlier compared to another form of payment, but have mixed awareness about interchange fee. It also indicated that interchange fee and cardholder benefits are independent of the merchant establishments. The study only broadly attempts to gauge merchants view if increased credit card usage has increased costs for them.

Due to the mobil-centered lifestyle following the wider use of Smartphones, Mobile services, including mobile banking and mobile shopping business have increased rapidly. Also with the emergence of "Fintech", which finance combined with technology, IT based financial market is going to be highly promising. In this trend, interests mobile credit cards are increasing. But diffusion of the mobile credit card services is still in the low level. In this situation, to identify factors that influencing satisfaction and continuous usage intention on mobile credit card, this study applied innovation diffusion theory (IDT) and post acceptance model (PAM). To conducting this research, survey data were collected, and we used SmartPLS to analyze survey data. As a result of the study, perceived easy of use, image, compatibility and facilitation positively affect user's satisfaction in mobile credit cards and that such satisfaction have a positive impact on continuous intention to use. The facilitation influences user satisfaction more strongly for those who use mobile credit cards more than plastic credit cards. Also, perceived of use and image influence user satisfaction more strongly for those who use plastic credit cards more than mobile credit cards. It is expected that this study can be a guideline for credit card service providers and policy makers to invigorate mobile credit card business. Also it worths as a early-stage research on Fintech-related studies.

With increase of internet users, usage frequency of e-mail card is growing up. In addition to advantage of delivering message in real-time, e-mail card contains words, animation and sound. So users can enjoy it's multiple characters. For these reasons, there is a shift in preference from traditional card to e-mail card especially in young age. In character portal sites sewing users with e-mail card it is regarded as useful media for character promotion. After bizarre rabbit 'Mashimaro' wins a great success as Flash animation, Flash card has been treated as an important media in character business. As the study on the aesthetic motive in Flash card, this thesis analyzes what is the meaning existing in characteristic expression of Flash card and proposes that the meaning is related to tension reduction from the viewpoint of entropy principle. We can summarize that contents of animation are based on striving toward simplicity and expressions of animation are based on catabolism. Both lead to pleasure of tension reduction. We can draw conclusion that pleasure of tension reduction becomes one of major factors of the aesthetic motive felt in Flash card.

In this paper, we propose a block adaptive binarization (BAB) using a modified quadratic filter (MQF) to binarize business card images acquired by personal digital assistant (PDA) cameras effectively. In the proposed method, a business card image is first partitioned into blocks of 8${\times}$8 and the blocks are then classified into character Hocks (CBs) and background blocks (BBs). Each classified CB is windowed with a 24${\times}$24 rectangular window centering around the CB and the windowed blocks are improved by the pre-processing filter MQF, in which the scheme of threshold selection in QF is modified. The 8${\times}$8 center block of the improved block is barbarized with the threshold selected in the MQF. A binary image is obtained tiling each binarized block in its original position. Experimental results show that the MQF and the BAB have much better effects on the performance of binarization compared to the QF and the global binarization (GB), respectively, for the test business card images acquired in a PDA. Also the proposed BAB using MQF gives binary images of much better quality, in which the characters appear much better clearly, over the conventional GB using QF. In addition, the binary images by the proposed BAB using MQF yields about 87.7% of character recognition rate so that about 32.0% performance improvement over those by the GB using QF yielding about 55.7% of character recognition rate using a commercial character recognition software.

This study examined the determinants of customer satisfaction in credit card service which has grown rapidly. We are interested in the determinants that affect intention of re-use and recommendation for the credit card. And in this study we adopt and extend the customer satisfaction factors presented in the literatures of retail banking services. The results show that the factors of corporate, innovativeness, physical & staff service and fee affect the customer satisfaction of the re-use intention. We also find that additional services, innovativeness and physical & staff service are the factors for the customer satisfaction of the recommendation intention. Finally, we discuss the managerial implications with a direction of future studies.
