Mobile Telemedicine uses common technologies that provide a conduit for information exchange between physicians nurses and patients. In addition to patient records, medical professionals will obtain vital signs and other reference data through Ubiquitous Sensor networks(USN). In this paper about a design and implementation of RFID reader platform that received RFID tag information from patients tags, transmit the data to SBC(Single board computer) based on Intel PXA255 ARM CPU and SBC transmit the data to MySQL server in hospital using by Wireless Internet. his system that based on Embedded Linux is composed of RFID module, ARM processor, RS-232 interface, and Wireless LAN. This paper also provides a brief overview and concept of RFID reader, and proposes the design and implementations of the RFID reader platform used QT and MySQL based on Embedded Linux.

The management system using the current RFID technology has the effects of reducing working hours and improvement in data processing, but it is not proper for human resource allocation since it is dominantly worked for physical resources. In this paper, we analyzed personnel control system using RFID of diverse environment and kinds of design in ship which analyzes presents of a monitoring system for safety operation and increase of efficiency in order to overcome the limitations and problems of current personnel operation management techniques using RFID.

In order to reduce a recent traffic accident, the traffic accident research has been studied using IT technique. But, when running away traffic accident it occurs, it is difficult to find the assault vehicle. In this paper, to solve these problems, if traffic accident will happen, The RFID reader will be able to recognize a license plate number automatically. Moreover, when the traffic accident occurs from the Internet base which uses the PDA the driver traffic accident site data and driver human fact it will be able to transmit in the police station or the insurance company. From the simulation result, it confirms that when passage vehicle speed is low speed above 70% it will be able to recognize the license plate number.

The introduction of radio frequency identification (RFID) technology into cold chain system will be essentials for the better quality preservation of chilled products in the near future. The object of this study is to analyze the trends of international standardization activity for cold chain system and RFID packaging. The standardization of RFID technology is related to SC31 of ISO/IEC JTC1. The established standard from EPCglobal includes the air interface of UHF substitute actors, the control of EPC tag data and the event collected from RFID readers, the directory services and information storage of ONS and EPCIS, and securities. Also, EPC standards include the sensor functions of the cold chain. In Korea, the RFID packaging related techniques and their engineering standard are less studied as compared with Europe or North America. For effective application of RFID in the cold chain and packaging, scientific and systematic researches on RFID, including technical standards for domestic RFID frequency, will be key elements for preoccupation of these application techniques.

The moving ranges and behavior of four wild abalones, Haliotis discus hannai, were measured by an acoustic telemetry technique. The shape of the sea bottom of the experimental area was surveyed by a bathymetry system and three self-recording type acoustic receivers were used for monitoring the behavior and measuring the movement range. The abalones (WA1-WA4) attached acoustic tags were released and measured the movement during ten months. Three abalones (WA1, WA3 and WA4) were successively detected around the released point during the experiment and were moved to the V2 area where water depth is deeper than the V1 area. The change of inhabitation depth was also detected from the depth sensor of WA4. As the result, abalones were moved to deeper water area accordance with the decrease of the water temperature. The moved ranges of abalones were approximately 200 - 400m from the release point.

Nowadays, the demand for the wireless technology has gradually increased to support the services of high speed wired internet and also the interest of a mobile terminal convergence has increased. In the next generation, the mobile terminal could merge with the celluar phone, wireless LAN, portable internet, digital multimedia brodcasting, mobile game and sensor(smart-tag and biometrics) through the unified single user interface. Moreover, the system is supported to multi-mode at difference networks, which have variable functions and high performance for available service. Inthis paper, we investigate the minimum requirements and the core technologies of the next generation mobile terminals.

This study was performed to develop a rapid test kit for pathogenic Staphylococcus in various samples. The rapid detection kit has been fabricated based on nitrocellulose lateral-flow strip. Colloidal gold and Staphylococcus antibodies were used as a tag and a receptor, respectively. Manually spotted Staphylococcus antibody and anti-mouse antibody on the surface of nitrocellulose membrane were used as test and control lines, respectively. Feasibility of the rapid kit to detect Staphylococcus aureus in samples were evaluated. The intensity of the color of the test line started to increase with the samples in which higher concentration of the cells were contained. The sensitivity of the sensor was $10^6$ cfu/mL Staphylococcus spiked in PBS. Also, the rapid test kit could detect $10^5$ cfu/mL of Staphylococcus in chicken meat extract.

In this paper, RFID (Radio Frequency Identification) based management system is introduced to control effectively logistic supply items and machinery spare parts in a ship. To apply an RFID system under very harsh environment in a ship which is a steel-structured small area with lots of compartment, we measured reading distances and angles in open space, in an steel compartment, and an real ship separately in order to investigate the reliability between various tags and RFID.

This paper presents a high performance HIGHT processor that can be applicable for CCM mode. In fact, HIGHT algorithm is a 64-bit block cipher. However, the proposed HIGHT extends the basic block length to 128-bit. The proposed HIGHT is operated as 128-bit block cipher and it can treat 128-bit block at once. Thus, it can be applicable for the various WSN applications that need fast and ultralight 128-bit block cipher, in particular, to be operated in CCM mode. In addition, the proposed HIGHT processor shares the common logics such as 128-bit key scheduler and control logics during encryption and decryption to reduce the area overhead caused by the extension of data block length. From the simulation results, the circuit area and power consumption of the proposed HIGHT are increases as 40% and 64% compared to the conventional 64-bit counterpart. However, the throughput of the proposed HIGHT can be up to two times as fast. Consequently, the proposed HIGHT is useful for USN and handheld devices based on battery as well as RFID tag the size of circuit is less than 5,000 gates.

In this paper, we designed and implemented ubiquitous u-Health system using RFE and ZigBee. We made a wireless protocol Kit which combines RFE Tag recognition and ZigBee data communication capability. The software is designed and developed on the TinyOS. Wireless communication technologies which hold multi-protocol stacks with RFID and result in the wireless ubiquitous world could be Bluetooth, ZigBee, 802.11x WLAN and so on. The environments that the suggested u-Health system may be used is un-manned nursing, which would be utilized in dense sensor networks such as a hospital. The the size of devices with RFID and ZigBee will be so smaller and smaller as a bracelet, a wrist watch and a ring. The combined wireless RFID-ZigBee system could be applied to applications which requires some actions corresponding to the collected (or sensed) information in WBAN(Wireless Body Area Network) and/or WPAN(Wireless Person Area Network). The proposed ubiquitous u-Health system displays some text-type alert message on LCD which is attached to the system or gives voice alert message to the adequate node users. RFE will be used as various combinations with other wireless technologies for some application-specific purposes.
