Recently, a number of record centers have reviewed the introduction of an RFID system for repository management. However, the RFID system currently in use by records management institutions is implemented with only a few functions for repository management. As such, a more efficient nonelectronic records management is required by improving the functions of the current RFID system. In this paper, the researchers proposed a method to improve its functions through an analysis of the RFID system being introduced for the management of nonelectronic records. To analyze the status of nonelectronic records management of records management institutions, the researchers investigated cases of the National Archives of Korea where RFID was introduced in 2007 and the records management institutions of local governments where RFID was introduced in 2016.

Recently, the Radio Frequency Identification(RFID) system has been growing with many promising features in technology and applications fields. Especially, a lot of efforts for the application of RFID system in the field of logistics management have been conducted. In addition, in logistics section of steel industry a remarkable efficiency can be attained by application of the RFID system. However, in the RFID system applied for the steel industry, lots of problems were found to be solved in recognition of the tags and antennas. This paper presents the feasibility of deploying RFID in the steel industry as a tool for reduction of the production cost. An application of the steel industry to RFID-based tracking management system was proposed. The results of this paper showed that the recognition rate of material input and output was found 100 percent and secured 99 percent of detection rate in the location. In conclusion, the proposed RFID-based tracking management system was approved superior to the existing system in terms of productivity.

This paper is an embedded system using the X-Hyper Intel PXA255 ARM CPU that base of the Linux operation system. This system applies tag information reading through RFID leader to Library executive system and designed and embody RFID middleware. The RFID middleware is consisted of RFID module, ARM processor and RS-232 interface. The RFID module is used to be inputted user and books information and RS-232 interface pass information by RFID middleware. Also, This system is embodied by specific Library management system using embedded exclusive use ARM processor. In this paper introduces concept and action principle of RFID middleware and uses Qt/Embedded and embodied manless loaning and return system.

This study analyzed the correlation between RFID acceptance intention and application, and as a result, extracted the technical stability, system quality and security of RFID as factors that affect the intention of receiving RFID in container terminal gate through preliminary research. This analysis was done on individuals engaged in container terminals which are in operation by adopting RFID in container terminal gate presently, and by distributing totally 255 copies of questionnaire survey, 248 copies were collected. As a result of statistical analysis of this study, the following conclusions were made: First, the technical stability of RFID acceptance in container terminal gate was not statistically significantly high. Second, the system quality and the security of RFID acceptance in container terminal gate were statistically significantly high. Finally, container terminal gate RFID technology acceptance intention was statistically significantly high in application performance.

RFID is core technology to lead ubiquitous computing, and attract the notice of the world. It also improves social transparency, creates employment, and invigorates the allied industries. However, The technical characteristic with RFID has some problems with security and privacy. The commercialization of RFID is delayed due to these problems. This paper introduces the technical method to find solutions about an invasion of privacy to be due to introduce RFID system. First, this method applies Hash-Chain proposed by M. Ohkubo and some other researchers. The more tags increase, the more it demands lots of computation time. We divide SPs equally to solve these problems. And then, We'll suggest solutions to shorten the identification time of tag by implementing SPs with multi nodes of Grid environment at the same time. This makes it possible to keep the privacy protection of RFID tag, and process RFID tag in real time at the same time.

Our research group has investigated that RFID tag packaging development and RFID tag flip chip bonding method influences on the industry-environmental customized RFID tag development that has applications to various industry environmental conditions. RFID tag flip chip bonding is consisting with wire bonding, ultrasonic bonding, heat plate bonding, and laser bonding and those methods are also depending on the different RFID tag development. Our research data shows that, among the various industrial environments such as an extremely high temperature, cryogenic, high-humidity, flexible, high-durable, development of RFID tag in an extremely high temperature is inappropriate for laser bonding method, converting of heat energy as absorbing light energy or heat plate bonding method of straight heat transferring manner, on the other hand, is suitable for wire bonding method which directly connect bump to pattern using wire.

RFID technology is applied to port logistics applications since it monitors objects wirelessly without line of sight and constructs ubiquitous system with low cost. Changes of stock status in the warehouse environment make the technology more important for managing such frequent storing and un-storing. Although the RFID has beneficial characteristics of low cost and low complexity, simultaneous responses of RFID tags cause tag identification collision due to absence of elaborate medium access control scheme. Several algorithms have been proposed to overcome the tag collision problem. However, it is difficult to adopt the methods to the logistics systems that has varying loads since there was no consideration on RFID tag's mobility. Therefore, we propose an efficient RFID tag anti-collision protocol, and simulation results demonstrate performance improvement by using the proposed scheme.

In Ubiquitous computing, RFID has been become a key technology to provide the real-time location information of users. For this purpose, many recent researches have been conducted regarding RTLS based on the RFID system. In this study, we evaluated the efficiency and feasibility of the velocity gauging system using RTLS based on the RFID system. By using this system, the velocity of mobile units were measured and the accuracy was evaluated with data obtained from DGPS. The results demonstrated that RTLS based on the RFID system would be suitable to measure with relatively low velocity information of mobile units. When RFID infrastructures are being constructed, the developed system will be a better position to increase popularity of velocity information service.

Tag collection is one of the major concerns in radio frequency identification(RFID) system. All tags in RFID reader's transmission range send response message back to the reader in response to collection request message on the given rf channel. When multiple tags respond simultaneously, tag-collision may occur. Tag-collision problem is one of the most important issues in active RFID performance. To mitigate this problem, frame slotted ALOHA(FSA) anti-collision protocol is widely used in active RFID system. Several studies show that the maximum system efficiency of FSA anti-collision protocol is 36.8%. In this paper, we propose an efficient slotted CSMA/CA protocol to improve tag collection performance. We compare our protocol to the FSA anti-collision protocol. For the experiment, an 433MHz active RFID system is implemented, which is composed of an RFID reader and multiple tags. We evaluated the tag collection performance using one RFID reader and 40 tags in the real test bed. The experimental result shows that proposed protocol improves the tag collection time, round and collision probability by 18%, 37.4% and 77.8%, respectively.
