As smart phones have became popular in recent years, use rate of smart phones application of mobile subscribers is now gradually increasing. Smart phones have a considerable effect on real life of users. Especially, mobile payment service using smart phones is outstanding in convenience because of its simple way to check out online. Therefore, in this paper, the database was designed for inquiring and making pre-order for take-out products based on connivence. This paper offers pre-order design to have order information standardized, menus which store owners can register and manage, and statistical data based on sales. It can be cost and time-efficient by using integrated pre-order system across all franchises. If this take-out pre-order system becomes more widely available, it will increase profit for both users and franchises due to cost and time efficiency.

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.

We propose a mobile point-of-sale system, which consists of only mobile information terminals and personal computers. The proposed system provides most of functionalities related with resource planning, adminstration and management, provided by medium-scale or large-scale POS systems, with additional functionalities, such as automatic information gathering and management through mobile interconnection, while eliminating the necessity of additional special-purpose devices, such as bar-code systems. The proposed system transmits order information through wireless and wired communication lines, thus allowing real-time sharing of order information among diverse information devices, such as mobile order receiving terminals, main server within stores, monitors and printers located in production lines. Also, the system is able to transfer such detail information produced within stores in real-time to the enterprise-level accounting, sales, logistics, personnel management system, which facilitate enterprise-wide management and administrative decision-making. No additional programs are required for mobile terminals. Order information received by such terminals are entered into databases through web server of main server and that information is again transferred to main server and production line printers. The proposed system can handle all the point-of-sale information and can provide almost of the POS functionalities by simply utilizing wireless internet, personal computers, and mobile terminals without installing specific-purpose peripheral devices. The proposed system can be widely applied to the small-scale stores and will contribute in reducing construction and maintenance cost required for point-of-sale management.

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.

Recently, the development and dissemination of smart devices linked to the network are being actively performed, and IOT(Internet of things) is issued form of mutually cooperative relationship through interoperation within smart devices. In this paper, we propose an innovative intelligent coffee shop management system by sharing and cooperatively controlling smart devices and Internet devices. The system can order smartphones including kiosk orders and beacon-based user identification. And it is a system that can make custom order without grasping user location information using geofence. The paper provides weather, temperature, time and user-based recommendation services based on Big Data. Therefore, the system is increased cost reduction and work efficiency than general coffee shops.

Shipbuilding is an order made assembly production basically. To build a single vessel, it costs hundreds of thousands small and big parts and million tons of structural steel. From contract to delivery, It takes 2 years of time in general. Shipbuilding parts are supplied order made based in and out of the country. For the cost and efficiency issue, on-time supply of ship parts is critical. Thus, this study suggests the optimum material management system plan of ship components for the best result.

최근 들어 우리는 VoiceXML에 관해 많은 기업들이 관심을 가지는 경우를 볼 수 있다. 많은 기업들은 이 기술을 통해 얻을 수 있는 이익이 과연 무엇인지 의문을 가지고 있는 것도 사실이다. 기존 기업들은 대부분이 자동 주문과 주문 추적 등 상거래 관리 기능을 담당하는 IVR 시스템과 웹 서버를 갖추고 있다. 만약 이러한 기업들이 VoiceXML을 사용하여 기존 IVR시스템을 재정비한다면 어떤 이익을 얻을 수 있을 것인가라는 질문에 대해 많은 VoiceXML업체들의 대답은 다음과 같다.

This study explores the importance of OSI standards in library environment and specifically of Z39.50/SR information retrival protocols and ILL protocol. Libraries and other information systems need to implement these ap lication protocols in order to facilitate the sharing of library information resources through information networks. The foreign systems which have implemented the standard protocols are reviewed in this paper, and it is suggested that search results of OPACs and other bibliographic databases be directly used for electronic document request for fast document delivery, first by implementing Z39.50 OPACs and standard interlibrary loan systems and next by integrating the two systems in Korean electronic libraries.
