As a result of the popularization of smart devices, smart phones or the tablets have become necessities in modern society. In this current of the times, the bring-your-own-device environment, in which personally owned smart devices are utilized in life, is attracting attention. In this context, this paper designed a Wi-Fi remote ordering system focused on the BYOD environment. If the Wi-Fi remote ordering system based on the BYOD environment is popularized, positive effects can be expected such as the enhancement of efficiency and the increase of customer benefits. As a typical example, real-time customer requests via smart devices enable the provision of fast services. This paper designed a mobile app for customers' remote ordering and web pages on which member stores can inquire details of orders, manage a menu, and register statistical data on sales. If the Wi-Fi remote ordering system designed by this paper is widely distributed internationally, it is expected that the system will be used usefully by many people.

Real time multimedia data services have been made possible by the rapid development of the computer and internet technology. Based on the technology, Many multimedia system developer try to use VOD(Video on Demand) and GVA technologies for distance education. However the system has mainly been developed to provide the video screen of good quality in real time and to compose contents efficiently. Not many researches and developments have been made for providing the users that is taking distance education with various types of service using VOD and GVA. Therefore In this paper we have designed and implemented an active on-demand multimedia service system to improve user-side service quality in distance education using VOD and GVA service. The on-demand multimedia service system can prominently help users to save the time and effort to search and select the studying data by this paper enables off-line search functions through E-mail and periodical current awareness service supported by PUSH technology, user oriented information booking supported by SDI service and feedback service.

Satellite operation is divided as user's request, image collection planning, product generation, distribution. Image collection planning is to make image collection plan of satellite to reflect user's request in proper time based on NTO (New Task Order) and AO (Archive Order) using limited satellite resources. Image collection planning has high computational cost because of considering several variables simultaneously, is to be performed identical process repeatedly. In this paper, optimization research of image collection planning is performed for efficient planning. First, formulation of image collection planning is made to require satellite image as much as possible and then Heuristic algorithm is suggested for solution of formulation.

최근에 시스템의 불법적인 침입, 정보 유출 등의 보안 사고가 많아지면서 컴퓨터 보안을 위한 많은 방법들이 제시되고 있다. 그 중에서도 컴퓨터 시스템 자체에 존재하는 보안상의 결함을 막기 위한 노력들이 있어왔다. 그러나 시스템의 보안 결함은 기본적으로 운영체제나 어플리케이션 자체의 버그에 기인하므로 끊임없이 출현하는 실정이다. 따라서, 시스템 관리자가 이를 일일이 확인하여 보안 결함을 체크하고 대응하는 것은 상당히 힘든 일일 것이다. 본 논문에서는 HTTP 프로토콜을 이용하여 클라이언트 시스템의 보안 결함을 원격으로 점검해 주는 주문형 보안 결함 탐지 서버(Security On Demand)에 대해 설명한다. 주문형 보안 결함 탐지 서버(이하 SOD 서버)는 서버-클라이언트 모델로서 클라이언트가 원하면 보안 결함을 탐지하는 코드를 전송하여 클라이언트 측에서 실행되도록 한다. 그러므로 SOD서버 측에만 새로이 출현한 보안 결함 탐지코드를 추가하면 클라이언트는 최신의 보안 결함에 대한 점검이 가능하다. 또한 코드 자체가 클라이언트로 전송되어 수행되기 때문에 클라이언트측의 보안 결함 정보가 서버로 유출되지 않는 장점이 있다.

Currently, Price comparison sites receive inputs of product information and price manually after being joined by releted shopping mall companies, and can't support automatically price fluctuation of products in real time. Therefore, this paper designs and implements web service system based on SOAP for interactive product order and price comparison dynamically using web service technologies in real time. This web service system composes web service client module including functions of product search, sort and order, and server module including functions of remote procedure call for product search and order. This web service system implements interchanging product information based on SOAP messages and can support independence of platform and flexible potability in environment conforming to SOAP, WSDL and UDDI standards.

This paper analyse the learners' satisfaction for the usability of distance teaming system. We have analysed collected data regarding the learners' satisfaction with the online Master's in Library and Information Science (MLIS) program as an example. The learner responses from the focus groups broke down into the following five themes: General program issues, Course issues, Communication/interaction issues, On-campus experience issues, Technology issues. The feedback can be applied to most online learning environments as a guideline for teaching and developing of online course.
