As building construction projects have been more higher and bigger in scale, the needs for cost reduction, productivity improvement, and reducing of work terms have rapidly increased in recent years. There has been, accordingly, a great emphasis on the necessity of logistics and progress management by well-organized system developed based on the appliance of different management theories. Although highly developed IT technology has contributed to the efficiency and effectiveness in information research and project management, RFID has been merely applied to a single progress or a few types of materials in current management studies, not to the overall process of the projects. This research proposes a consistent and systemized approach for decision making in adopting RFID technology in a construction project to support construction logistics and progress management. With a decision making model that consists of process model and template developed in this research, risks in cost, time, and error in building RFID-based construction logistics and progress management could be minimized.

This paper presents the design of a 920 MHz ultra-high frequency(UHF) band radio frequency identification(RFID) conductive fabric tag antenna. The resistance values of four different conductive fabrics are measured, and the conductivities of the fabrics are calculated. The fabric with the best conductivity is selected, and the best conductivity of the fabric is used to simulate the fabric tag antenna design. The fabric UHF RFID tag antenna with a T-Matching structure and name-tag size of $80{\times}40mm$ is simulated and designed. The simulated and measured results are compared, and a laundry test is performed. The reading range of the fabric tag antenna is about 2 m. This fabric tag can be easily applied to an entrance control system as it can be attached to other fabrics and cloths.

Today, Korean medical community faces rapid changes in medical environment due to opening of medical market, more emphasis on making profit and introduction of private medical insurance. Therefore, it is apparent that around, major university hospitals, efforts are being made to adapt to such changes by establishing mid to long range strategic plans. We want to keep pace with changing times and diverse demand of patients by introducing state of the art system, utilizing Ubiquitous technologies for improvements. In doing so, we want to distinguish our hospital services from others. However, Hospital Information System that integrates ubiquitous technologies are introduced in limited basis due to problems like standardization and limits on medical use etc. Particularly, problems like absence of tag design suitable for medical environment, compatibility and extension issue with RFID system need to be addressed on application of RFID technologies. In order to solve such problems, this paper implemented RFID tag system, RFID-SIP UA program, location tracking program. This paper provides a comprehensive basic review of RFID and SIP model suggests the evolution direction of further advanced RFID application service. The design of RFID-SIP application offers advance RFID system with drawback and reduction search time of medical object. so there is a improvement of hospital information system in ubiquitous environment.

Since 2004, the Korean government has been engaged in u-IT new technology verification projects in an effort to level up the industries. Recently, cases are reported that RFID/USN technology has been adopted and applied to business processes, mainly by large enterprises. However, further policies and support for the industries have been restrained because of unavailability of essential data for policy making. Therefore, the study examined the level of satisfaction among the actual recipient organizations from the 27 pilot projects to draw implications from the study result. Accordingly, the level of satisfaction was assessed in four project phases from RFID/USN building, utilization (technical quality), utilization (business quality), to maintenance. The study result showed that the technical stability reached a significant level but the level of satisfaction in the maintenance phase for the utilization and proliferation of the technology remained at the lowest. It suggested that a more specified policy support is needed in the maintenance phase to include inexpensive supply of tags and devices, a maintenance establishment of consortium to maintain reliability and continuity of service, strengthening internal competence of the beneficiary organizations for utilization of RFID/USN.

Because RFID systems use radio frequency, they have many security problems such as eavesdropping, location tracking, spoofing attack and replay attack. So, many mutual authentication protocols and cryptography methods for RFID systems have been proposed in order to solve security problems, but previous proposed protocols using AES(Advanced Encryption Standard) have fixed key problem and security problems. In this paper, we analyze security of proposed protocols and propose our protocol using OTP(One-Time Pad) and AES to solve security problems and to reduce hardware overhead and operation. Our protocol encrypts data transferred between RFID reader and tag, and accomplishes mutual authentication by one time random number to generate in RFID reader. In addition, this paper presents that our protocol has higher security and efficiency in computation volume and process than researched protocols and S.Oh's Protocol. Therefore, our protocol is secure against various attacks and suitable for lightweight RFID tag system.

After the Davos Forum, the recent 4th Industrial Revolution has become an area of interest to countries around the world. Among the technologies of the 4th industrial revolution, the ubiquitous computing environment requires a convergence environment of various devices, networks, and software technologies, and the RFID technology that identifies objects among the IoT technology fields is applied to all industries and has a competitive edge. Systems to which RFID technology is applied are being used in various industrial fields, especially! It is efficiently used for accurate inventory management and SCM management in the field of distribution and logistics. If the RFID system is built in a cloud-based environment, it will be possible to secure reliability in distribution management in consideration of an effective logistics management system and economic feasibility. This study is a study on the RFID system in a cloud computing environment to reduce the cost of operating or maintaining an application server to improve the economy and reliability.

A low-power Radio Frequency Identification (RFID) system is an auto-identification technology that reads and writes an information of things without physical contacts using radio frequency. It is unescapable against unlawful modification, eavesdropping, tracking, or privacy of individuals because RFID systems use the radio frequency and RFID tags. Therefore we create a key using hash chain between database and tag and this process can prevent above attacks. Also we support the efficiency of proposed protocol using hash function to abate computation.

RFID는 무선 주파수를 이용해 사물이나 사람에 부착된 태그를 인식하고 태그에 담긴 정보를 주고받을 수 있도록 하는 비(非)접촉식 정보인식기술을 뜻하며 USN(Ubiquitous Sensor Network)의 핵심기술로 주목받으면서 다양한 분야에 걸쳐 연구되어 왔다. 기존 RFID와 이동통신 인프라를 융합한 모바일 RFID는 기존의 RFID 시스템과 모바일 네트워크의 장점을 동시에 지닌 개념으로써, RFID를 이용해 보다 다양한 서비스 제공이 가능할 것으로 기대되고 있다[1][2][3]. 2007년, Kim 등은 모바일 RFID 프라이버시 보호기법에 관한 논문을 발표하였다[4]. Kim등은 논문에서 개인 사용자들이 각각 모바일 리더를 소지하고 이를 상품구매 시 이용하는 환경을 가정하고, 이 때 발생할 수 있는 위협과 이에 대한 해결책을 제시하였다. 그러나 주장과는 달리 제안된 기법은 위치추적에 대해 안전하지 못하며 사용자 프라이버시를 보장하지 못한다. 본 논문에서는 Kim등이 제안한 기법을 소개하고 실제 공격이 이루어지는 과정을 통해 제안된 기법의 취약성을 설명한다.

RFID technology can help automatically and remotely identify objects, which raises many security concerns. We review and categorize several RFID security and privacy solutions, and conclude that the most promising and low-cost approach currently attracts little academic attention. We therefore concluded that, from a privacy perspective, the user scheme is an important strategy for meeting the consumer's needs. Furthermore, we call for the privacy research community to put more effort into this line of thinking about RFID privacy.
