최근의 웹 서비스 기술은 주문을 받아서 만드는 클라이언트 애플리케이션을 위한 서비스 수단을 제공하기 위해 기능이 향상된 솔루션으로 개발되고 있다. 특히 웹 서비스는 현재의 웹 포털 사이트보다 서버들로 융통성 있는 접근을 제공한다. 즉 웹 서비스를 사용하는 것은 클라이언트 애플리케이션이 인터넷을 단순하게 표시하는 기능만을 하는 것이 아니라 시스템간의 정보 교환을 자동화함으로써 프로세스의 성능을 향상시키는 것이다. 이 논문에서는 웹 서비스 기반 eCard 메일 전송 시스템을 기술하고, 시맨틱 웹 서비스 언어를 이용하여 eCard 웹 서비스를 표현하는 것에 대해 기술한다.

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.

This paper presents an edutainment robot for young children. The edutainment robot called 'Mon-e' has developed by the Central R&D Laboratory at KT. The main services of the Mon-E robot are autonomous moving service, object card and story book telling service and videophone service. The RFID technology was introduced for easy interface to young children. The face of Mon-E robot is mounted with an RFID reader. The RFID tag is pasted on story book and object card. If you approach a book or an object card to the face of Mon-E, the Mon-E robot recognizes the identified code and plays its service. In autonomous moving, if the Mon-E robot meets obstacles, it moves back and turns left or right or half rotation. In videophone service, if young children approach an RFID card to the Mon-E, the Mon-E can make a call to the specific number, which is contained in the RFID card. The developed Mon-E robot has tested in real world environment and is evaluated young children and their parents. In the result of evaluation, the feeling of satisfaction was high to main services of Mon-E robot.

Electronic identity (e-ID) card based on smartcard is a representative identity credential for on-line and off-line personal identification. The e-ID card can store the personal identity information securely, so that the information can be accessed fast, automated identity verification and used to determine the cardholder's authorization to access protected resources. Due to such features of an e-ID card, the number of government organizations and corporate enterprises that consider using e-ID card for identity management is increasing. In this paper, we present an authentication framework for access control system using e-ID cards by discussing the threat environment and security requirement against e-ID card. Specifically, to accomplish our purpose, we consider the Personal Identity Verification system as our target model.

This study addresses some solutions of the technical problem of using e-money systems. The solutions are on/off line e-money, one card, ordering system, and card-card settlement system etc. The alternatives are described as source code in the example of Angel Plus e-money. E-money is classified as IC card(off-line) type and net work(on-line) type. But, They should be integrated. End-users want to use the combined card for its conveniences. This research introduces on/off line e-money with a case study. On the basis of this paper, future research is to be further conducted on the Customer-oriented e-money with multiple functions.

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.

The purposes of this article is to analyse how market competition of credit card company affect price(interest rate) and survival length of card users. This paper uses individual account data from a large Korean credit card company during the periods from 2002 to 2006. The findings of our study are as follows. First, market competition of credit card company have a negative effect with interest rate of credit card. Second, market competition of credit card company have a affirmative effect with survival length. Finally, The effect of Increasing delinquency rate due to price increase is smaller than decreasing delinquency rate due to extending survival length.

E-Card Service for Child Nutrition Program is one of the main public policy services nowadays. In case of inconvenience during the use of the e-cards, it is recommended to cooperate with related organizations in order to promptly handle and provide guidance, and thoroughly manage child feeding service such as hygiene, nutrition and kindness etc. To do so, it is very important to provide food service that meets local actual conditions and children's needs in a cost effective manner for the underage who are worried about the poorly-fed by understanding the pattern of child feeding e-card service. Hence. this paper aims to investigate how child feeding e-card service efficiently provides meals according to the local situation and children's needs through big data analysis and to propose a method of identifying welfare conditions according to the purpose of service with actual application examples. The results suggest that, first of all, this study is able to judge appropriateness of public institution's policy in a timely and repetitive manner through non-standard data analysis such as Naver News and transaction data. Secondly, this paper proposes a multi-layered analysis framework, which performs online open data analysis to detect policy issues, visualizes retrieval and preprocessing of real data, and performs abnormal pattern recognition. These will be worthy of reference to other similar projects.
