Radio Frequency IDentification(RFID) is in the limelight of fields of military, delivery and library management as an alternative or barcode system. However, it is restricted within product manufacturing, sales and delivery. In this paper, we apply RFID technology into process, especially packing process management to gauge RFID applicability. To verify beneficial features of RFID, we simulate RFID-adopted packing process. As a result, we demonstrate the effectiveness of a RFID-based Process Improvement In manufacturing process. The results of performance evaluations demonstrate that the proposed RFID-based Process Improvement reduces the labour time, labour cost and material cost. Furthermore, we analyze the validity of RFID-based Process Improvement by RFID cost.

Since libraries first used RFID systems in the late 1990's, there is growing debate about the advantages and disadvantages of HF and UHF RFID systems. This study tries to explore practical issues in HF and UHF RFID systems especially in the areas of system characteristics and advantages and disadvantages affecting technology implementation to libraries. This study investigates the current status of RFID systems in Korean libraries, and analyzes the best practices of four libraries(two libraries in HF and two libraries in UHF respectively). Also, this study describes functional characteristics of HF and UHF RFID systems, debates on frequencies in ISO/DIS 28560, and the opinions of both manufacturers which provide RFID systems to libraries and librarians who use HF and UHF RFID systems in their libraries.

Global interests in RFID are increased and Korean government and companies make an active effort to propagate and spread RFID. Due to the overwhelming advantages of RFID system in comparison with existing bar code system, ripple effects on logistics sector among the utilizing fields of RFID technology are expected to be great, but application of RFID system is lowly progressed unlike the expectation of several experts. Therefore, this research extracts precedent studies on theoretical background, applying fields, promotion condition and domestic/foreign parts of RFID system, factors for operating domestic RFID system and effects and considers the effects of RFID's external variables on easiness and effectiveness of TAM. It confirms the relations of RFID applying effects for companies applying and utilizing RFID and verifies the relations among the effects for application of RFID system, accepting intention of RFID system and applying effects. Based on the results of analysis, it should play a role of good guide for all of companies and institution who will introduce RFID system to all of Korean logistics fields, make policies and systems which promote RFID acceptance nationally and socially and play a role of guide making confident climate for RFID technolog

The existing patient monitoring system when the patient want own information. The patient confirm information through the medical institution. But the patient monitoring system based on the U-Healthcare, the patient always confirms own information through the mobile device including rfid reader. The patient need RFID middleware design to provide wanting service when the RFID reader read patient's tag information. The RFID middleware is consisted of RFID module, ARM processor and RS-232 interface. The RFID module is used to be inputted user information and RS-232 interface pass information by RFID middleware. Also, This system is embodied by specific patient monitoring system using embedded exclusive use ARM processor. In this paper introduces concept and action principle of RFID middleware and embodied patient monitoring system that use Qt.

For realizing ubiquitous computing, many research activities are geared towards various areas including embedded computing, RFID, USN, home networking, context-awareness, and etc. By using the ability of RFID technology to recognize a number of objects simultaneously, more convenient ubiquitous application services are effectively provided. In this case, RFID middleware playing a role as a bridge between RFID reader devices and application services is required as well. In this paper, we propose a method of handling a number of types of RFID reader devices in ALE middleware of EPCglobal. For this, the information of connection and data protocol for a reader device is stored in a database as ontology meta-data, and used to interpret the data read by a reader device. By adding ontology data into a database, even though an RFID device newly emerges, ALE middleware can not only handle the device, but also be effectively extended through reusing ontology data, without any changes in the middleware.

The information flow through RFID techniques such as, standardized EPC and EPCglobal network suggests new change in the method of cooperating and sharing information in the supply chain. Common function should be prepared for communication, security techniques, and business processes based on the EPCglobal standard to introduce efficient RFID techniques. And the standard architecture which can deal with the RFID environment flexibly is quite necessary. Therefore, this paper suggests Enterprise Application Framework (EAF) for developing efficient and secure RFID applications. EAF offers essential services to develop RFID enterprise systems : a communication environment which uses various standard communication protocols, a security function based on PKI, and abstract business services for flexible introduction of RFID businesses. It simplifies the RFID business integration, minimizes the development complexity, and thus EAF is expected to reduce the cost of RFID application development. EAF guarantees constructing secure RFID applications due to PKI-based security mechanism.

Previous RFID systems exclusively manage the tags and readers for each company in individual manner. Thus, RFID system manager should understand and design specifications such as tag events, data format, and etc, based on individual companies. But it is very difficult to know all statements. To resolve theses problems, there has been conceptual research about policy-based RFID service management model that is not restrained from standards of typical RFID systems, including EPCglobal standard, and ISO/IEC standard. However, previous proposed service management model only aimed event management without including device management. Therefore, in this paper, we propose extended device management policy model for giving shape to the proposed policy-based RFID service management model. If the proposing device management policy model is used for device management, we can integrate control management for heterogeneous middleware, diverse RFID devices, and applications for each company. Moreover, we show that the RFID device management policy is translated and processed as an example using the proposing policy model in real-time RFID system.

An RFID middleware system that can process a large volume of RFID data became necessary with the advent of various kinds of ubiquitous services. In this paper, we propose a method to process massive RFID data and provide it to client applications based on ALE-compliant RFID middleware systems. To distribute the requests to collect and process the RFID data from clients, the proposed system gathers the resource information for RFID middleware systems and processes the requests from clients according to the information.
