Recently, the mRFID which combines RFID system a mobile uses infra of mobile communication and it provides object information service with the form which is various. Currently, many object information service system exists. But such system object information is by a service box and becomes the inclusion in specific territory and connection it does from different territory, there is a difficult problem point. It secured the weak point of object information service system of existing from the dissertation which it sees and the object information service system which is suitable in application development of the mRFID it embodied.

The trend in construction industry, now, lies in improving efficiency and competitive power in construction management and on-the-spot instruction by combining with new IT technology. Above all, it is safe to say that the application of RFID technology can play a pivotal role at this point, but it is not that easy to apply RFID due to the physical, chemical and environmental peculiarities of construction materials. Thus, a study on the standardization of the usable frequency, specifications, protocol, and package administration is required. This study, as part of the study on the standardization, figured out the restrictions by attaching the existing RFID Tag to the construction materials, turned out the prototype of RFID Tag to perform a field test. In result the effective recognition range varies according to the physical and environmental peculiarities of construction materials; and the management efficiency varies as the attaching method and/or applying method. To analyze the management method (media, process etc.) systematically for the existing construction materials; to prepare more various restrictions and its solutions for practical construction spots will be the key for successful RFID implementation.

우편 물류 환경에 RFID 기술을 도입하는 경우 가장 먼저 기대할 수 있는 효과는 비용절감이다. 두번째는 우편 물류 처리시간의 단축과 이로 인한 우편물 처리 용량의 증대효과이다. 본 고에서는 우편 물류 환경에서 RFID 기술 도입 시 그 시행 착오를 줄이고 보다 효율적인 RFID 기술 도입을 위해 현재의 RFID 기술 수준을 파악하고, 국내외RFID 기술 도입 사례를 제시한다. 이를 위해 현재의 RFID 기술에 대한 국제 표준화 상황과 RFID 기술 상용 제품의 가격과 성능 수준 그리고 RFID 기술 도입 사례 등을 기술한다.

In this paper, we propose an application model of RFID that needs not be worried about battery degradation problems and offers convenience of hand-carry. We design the RFID application model which can track medium distance target RFID Tag and detect the signal difference between multi-detectors in a room area using 900MHz frequency band. In the case of multi-ID Tag in one detector, we approach TDMA scheme.

At present, companies write daily work record or use bar-code in order to collect distribution flow data in real time. However, it needs additional works to check the record or read the bar-code with a scanner. In this case, human error could decrease accuracy of data and it would cause problems in reliability. To solve this problem, RFID (Radio Frequency Identification) is introduced in many automatic recognition sector recently. RFID is a technology that identification data is inserted into micro-mini IC chip and recognize, trace, and manage object, animal, or person using wireless frequency. This is being emerged as the core technology in future ubiquitous environment. This study is intended to suggest RFID application method in franchise business. Traceability and visibility of individual product are supplied based on EPCglobal network. It includes DW system which supplies various assessment data about product in supply chain, financial transaction system which is based on product transaction and position information, and RFID middleware which refines and divides product data from RFID tag. With the suggested application methods, individual product's profile data are supplied in real time and it would boost reliability to customer and make effective cooperation with existing operation systems (SCM, CRM, and e-Business) possible.

Recently, the government has established the synthesis measures of RFID/USN application, plans to facilitate 16 most priority fields as a leading business, and has kept making efforts to spread the application by making RFID attachment mandatory on harbor and distribution industry. In spite of these efforts, it is necessary to analyze actual state of each industry and institution demanding RFID/USN to lead it to induce them. This study tries to draw the method of spreading RFID/USN usage by analyzing and verifying the actual situation of their application and its problems, and to figure out how to improve the problems in each sector on the basis of the analysis by comparing and analyzing the obstacles in their wide usage.

Nowadays there are many studies and there's huge development about RFID and WSN which have great developmental potential to many kinds of applications. In particular, the healthcare field is expected to could be securing international competitive power in u-Healthcare and combined medical treatment industry and service. More and more real time application apply RFID and WSN technology to identify, data collect and locate objects. Wide deployment of RFID and WSN will generate an unprecedented volume of primitive data in a short time. Duplication and redundancy of primitive data will affect real time performance of application. Thus, emerging applications must filter primitive data and correlate them for complex pattern detection and transform them to events that provide meaningful, actionable information to end application. In this paper, we design a complex event processing system. This system will process RFID and WSN primitive data and event and perform data transformation. Integrate RFID and WSN system had applied each now in medical treatment through this study and efficient data transmission and management forecast that is possible.

We conduct an empirical study on RFID application to a real container terminal gate. The objective of this study is three-fold. The first is to design a new gate management process that applies RFID technology. For this purpose, we analyze current gate management process to find opportunities for improvement. The second is to verify the 433 and 900 MHz RFID technology in terms of the recognition rate of information contained in RFID tag under various conditions such as the speed of vehicle, the position of RFID tag and the tilt of RFID reader. We perform some experimental tests for this verification. Finally, we try to find suitable conditions for the speed of vehicle, the position of RFID tag and the tilt of RFID tag reader based on results of the experimental tests. Those findings are obtained with some ANOVA tests. Additionally, we summarize anticipated issues when applying RFID technology to the gate management process and possible solutions for the issues.

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.
