Tourism and hospitality have encountered significant changes in recent years as a result of the rapid development of information technology (IT). Customers now expect more expedient services and customized travel experiences, which has intensified competition among service providers. To meet these demands, businesses have adopted sophisticated IT applications such as ChatGPT, which enables real-time interaction with consumers and provides recommendations based on their preferences. This paper focuses on the AI support-prompt middleware system, which functions as a mediator between generative AI and human users, and discusses two operational rules associated with it. The first rule is the Information Processing Rule, which requires the middleware system to determine appropriate responses based on the context of the conversation using techniques for natural language processing. The second rule is the Information Presentation Rule, which requires the middleware system to choose an appropriate language style and conversational attitude based on the gravity of the topic or the conversational context. These rules are essential for guaranteeing that the middleware system can fathom user intent and respond appropriately in various conversational contexts. This study contributes to the planning and analysis of service design by deriving design rules for middleware systems to incorporate artificial intelligence into tourism services. By comprehending the operation of AI support-prompt middleware systems, service providers can design more effective and efficient AI-driven tourism services, thereby improving the customer experience and obtaining a market advantage.

The development of information technology, which has brought the fusion of broadcasting and telecommunication, wire and wireless communication and voice and data, is developing new fusions like home network which is composed of IT, construction, and home appliances. This trend is considered to continue and to make other new fusions based on previous ones. In this study, we investigate the roles of RFID middleware by identifying the relationships between the new expected fusions and RFID.

This paper deals with the middleware development for real time data processing using ubiquitous RFID(Radio Frequency Identification). This middleware system supports the real time data gathering, filtering, and collaborative operations within SCM. We expect to decrease the data processing cost and to upgrade the status of RTE(Real Time Enterprise) and competitive power of company.

본 논문은 USN(Ubiquitous Sensor Networks) 구축에 활용될 WMN(Wireless Mesh Networks) 기반의 미들웨어 설계에 대해 기술한다. WMN 기반의 미들웨어는 넓은 범위에 걸쳐서 분산되어 있는 센서 디바이스들로부터 상황인지에 필요한 데이터들을 WMN을 통해 미들웨어와 연동하는 기술이다. 본 논문에서 제안하는 WMN기반의 미들웨어는 WMN을 활용하여 인프라 구축이 미흡한 곳에서 정보 교환을 가능하게 하고, 특정 센서로부터 발생된 이벤트를 Context-awareness를 통해 종합적으로 분석한 결과를 바탕으로 사전에 사용자에 의해 설정된 제어값을 참조하여 주변장치를 실행한다. 미들웨어는 센서 네트워크 관리와 응용서비스를 상호 분리하여 각각의 기능을 수행한다.

Recently, MPEG (Moving Picture Experts Group) has started a new standardization activity called MPEG Multimedia Middleware (M3W). This activity covers the standardization for a middleware rrith a set of APIs. The standard middleware, called M3W, will support independent multimedia applications for hardware and software such as operating systems so that the portability and interoperability of multimedia applications are greatly improved. In this article, we will introduce the recent works on M3W standardization including the rationale that motivates the activity with the advantages of having the standardized middleware for multimedia application, component technologies being considered for the M3W, and the current status of the standardization.

Normally, a distributed computing environment is flexible in controlling complex embedded systems but their software components are becoming complex as these systems are equipped with several platforms and attached to various electronic devices, sensors, and actuators. These systems requires inter-object communication mechanisms to provide fault tolerant and QoS-enabled middleware service support in a distributed system. Generally, a middleware performs analysis of the parameters to ensure the availability and reliability of data dissemination. This paper focuses in particular to designing an application middleware for the specific scenario to improve the high availability and fault tolerance of data thus improving the QoS (Quality of Service) of a distributed system. The performance of an adaptive and highly reliable middleware can be significant based on the selection of vital parameters of the system.

기존의 미들웨어 시스템이 유선 환경을 중심으로 기초로 개발됨에 따라 모바일 무선 이동성 환경을 지원하기 위해서 미들웨어 및 관련 응용 프로그램들이 규모 또는 운용성이 커서 적용되기 어렵다는데 문제가 발생한다. 이러한 문제점을 극복하기 위해서 미들웨어 응용 및 실행 단위가 모바일 환경에 적합하게 최소 및 최적화되어야 하므로 이에 필요한 경량모바일 시스템을 설계 및 제안 한다.

The active rule system is a key element of the rule-based mobile agent middleware system for activeness and autonomy of the sensor network. The rule manager, which is the main components of active rule based mobile agent framework and active rule system, performs the control and management of the rule-related processes. In this paper, we design and implement the roles and functions of the rule manager in detail. The proposed rule manager plays an important role in the sensor network environment. The sensor data server loads the active rule on the mobile agent by the rule manager according to the situations, and the mobile agent migrates to the destination node and performs the designated action. This active rule-based mobile agent middleware system presents the usefulness for the various sensor network applications. Through the rule execution experiment using the rule-based mobile agent, we show the adaptability and applicability of rule-based mobile agent middleware system to the dynamic environmental changes in sensor networks.

Recently, RFID(Radio Frequency IDentification) has emerged as the main technology in the logistic services. When the existing recognition technology based on bar codes brings about lots of problem due its own limits. RFID becomes the center of attention to solve them. However, RFID is not without any obstacles : companies have their own operating systems. while RFID is developed regardless of each campany's special features. RFID middleware system based on web service is expected to remove these obstacles. This paper shows how to operate the middleware based on web service and to lay in the DB the tag informations taken from reader system Middle assures that companies adopting RFID system for their logistic service are given athptabwebty to any systems whatsoever, avaweable by way of defining logistic information, tag information and reader information. For this purse, we implement as the basic web service a middleware system that turns all data into XML(eXtensatle Markupmsngunfo) of SOAP(Simple Object Access Protocol), the standard data.
