As the scale of domestic building construction becomes larger, more complicated and more specialized, demands for quality improvement, cost reduction and construction period shortening increase. Construction materials management becomes a main factor to perform the project successfully. Therefore, various researches using RFID(Radio Frequency Identification) are being studied to manage the construction materials efficiently. This research aims to suggest the method of construction materials management using RFID in apartment housing. First, the technical properties of RFID are grasped. Second, problems are extracted by analyzing the case studies and related research using RFID in construction field. Third, construction materials are classified according to the construction process and process of materials management is analyzed. Lastly, method of construction materials management using RFID is suggested. The results of this research are expected to contribute the improvement of construction productivity through effective material management.

RFID(Radio Frequency IDentification) is appearing by point technology by Ubiquitous environment of new paradigm and Logistics' application. But, RFID chip of this is high price and short bandwidth, low power and interference etc. can become technological problem. This is getting into obstacle in common use. Reader and tag, Embedded software etc.. that is accomplishing standardization is imported paying most expensive Royalty. This paper is RFID cognition system that use PDA in Ubiquitous environment to apply to Logistics system. RFID cognition system processes input/output of fundamental information attaching tag to Logistics of products. And RFID cognition system supports quick and correct and safe synthetic Logistics managerial system through construction of database. This can prove minimization and customer service of Logistics expense. RFID cognition system is advantage that can widen range of application to area that cognition system of existent fixing style can not do. Also, It can expect economical effect through inexpensive system construction.

With the development in IT technology and with growing demands of users, a ubiquitous environment is being made. Because of individuals identification is important in ubiquitous environment, RFID, a technology used frequently. RFID, a technology that radio frequency identification, reader send signer, then tag provide user information. RFID has various strengths, such as high recognition rates, quick recognition speed, but Eavesdropping is possible and problem that user information is revealed happens. To solve this, study is proceeded with activity, but, because of low-cost passive tag is limited operation capability, usually used hash function and random number. Also updates value that is used to present session and uses in next session. Therefore, this scheme protects user privacy using random number. And this sheme can offer synchronization by creating variable value without updating value.

In this paper, we present an integrated management system for radioactive waste, which can keep watch on the whole transporting process of each drum from nuclear power plant temporary storage house to radioactive waste storage house remotely. Our approach use RFID(Radio Frequency Identification) system, which can recognize the data information without touch, GSP system, which can calculate the current position precisely using the accurate time and distance measured from satellites, and the spread spectrum technology CDMA, which is widely used in the area of mobile communication.

Recently, as the development of Radio Frequency Identification (RFID) technology becomes active, the demand for services which can electronically manage the history and location information of major trees, including trees for cultural heritage restoration and nurse trees, has been increased. This information has been managed by separated drawings and documents or storing its information into PDAs and then structuring data files through input and computation. But, these methods imply limitations in terms of its extensibility and scalability. This paper has designed and implemented an RFID based Tree History Information System (THIS) for cultural heritage restoration. The purpose of the proposed system is to support to be able to effectively and consistently manage historical information of major trees and improve working processes by implementing mobile RFID services through wireless Internet or Local Area Network (LAN) as mobile communication networks. Through implementation, it is confirmed that the proposed system can manage the historical information of major trees more effectively than conventional methods and also improve previous field working conditions.

A RFID (Radio Frequency Identification) system receives attention as the technology which can realize the ubiquitous computing environment. However, the feature of the RFID tags may bring about new threats to the security and privacy of individuals. Recently, Juels proposed the minimalist cryptography for very low-cost RFID tags, which is secure. but only under the impractical assumption such that an adversary is allowed to eavesdrop only the pre-defined number of sessions. In this paper, we propose a scheme to protect privacy for very low-cost RFID systems. The proposed protocol uses only bit-wise operations without my costly cryptographic function such as hashing, encryption which is secure which is secure against an adversary who is allowed to eavesdrop transmitted message in every session any impractical assumption. The proposed scheme also is more efficient since our scheme requires less datas as well as few number of computations than Juels's scheme.

지금 국내를 비롯해 세계는 소위‘전자태그’라 불리우는 RFID(Radio Frequency Identification)에 대해 많은 얘기들이 나오고 있다. 이미 일부 분야에서 RFID 도입이 이뤄지고 있으며 향후에는 유비쿼터스의 핵심 기술로 우리의 일상 곳곳에 적용될 것으로 보인다. 국내에서도 정보통신부, 산업자원부 등 정부 주도로 5개 시범 기구를 선정해 RFID 방법론을 개발하고 있고 이를 기반으로 민간 산업에 확산시킨다는 전략을 펼치고 있다. 칩가격·표준·보안 등이 해결해야 할 문제이지만, 앞으로 미래시장의 확실한 블루오션이 될 것으로 기대되고 있다.
