As the hand-held mobile devices are widely used, they are recently coming into convergence with medical diagnostic systems. Furthermore, the wireless mobile Internet and the various kinds of communication devices are rapidly coming into wide use converging with medical technology. The mobile communication environments can make people get more health care services beyond space and time. In this paper, we implement and evaluate the mobile client and the medical diagnostic information server for transmitting, searching and updating the medical diagnostic information. The DICOM CT image and the compressed JPEG 2000 CT image are statistically evaluated by t-test performance whether those images are clinically appropriate. In the case of the DICOM CT image, we realize that the average value is relatively more appropriate to the clinical diagnosis than the JPEG 2000 CT image.

An integrated medical information system should be equipped for the activation of u-healthcare service. In addition, the integrated medical information system should be based on an authentication system to be implemented in a safe environment. However, several requirements are being developed yet. In this paper, biometric authentication system will be designed and proposed for u-healthcare services for the integrated medical information system to go one step further.

Recent advancement of USN technology has lent itself to the evolving communication technology for implantable devices in the field of medical service. The wireless transmission section for communication between implantable medical devices and patients is a cause of concern over invasion of privacy, resulting from external attackers' hacking and thus leakage of private medical information. In addition, any attempt to manipulate patients' medical information could end up in serious medical issues. The present study proposes an authentication protocol safe against intruders' attacks when RFID/USN technology is applied to implantable medical devices. Being safe against spoofing, information exposure and eavesdropping attacks, the proposed protocol is based on hash-function operation and adopts session keys and random numbers to prevent re-encryption. This paper verifies the security of the proposed protocol using the formal verification tool, Casper/FDR.

컴퓨팅 및 네트워크 기술이 발전함에 따라 그리드 응용의 복잡도 및 컴퓨팅 요구사항이 커지게 되었으며, 이로 인해 그리드 워크플로우 관리 기술의 중요성이 더욱 부각되었다. 이러한 복잡한 그리드 응용을 위해 다양한 그리드 워크플로우 관리 시스템이 개발되었으나 사용자의 요구사항에 대한 고려, 안정성 그리고 사용자와의 상호작용 등의 기능이 부족하였으며 특히 자원관리 기능에 대한 지원이 부족하였다. 본 논문에서는 기존의 응용 친화적인 워크플로우 관리 시스템과 그리드 워크플로우 관리 시스템을 정책 기반 메커니즘을 이용, 통합하여 새로운 Hybrid 형태의 워크플로우 관리 시스템을 제안하였으며, 제안하는 방법이 어떻게 사용자의 요구수준을 만족시킬 수 있는지를 서술하고 이를 대사증후군을 위한 질병진단 시스템에 적용하여 실험적으로 증명하였다.

In this letter, a small-sized ultra-high frequency (UHF) RFID tag antenna for a medical sample tube is proposed. The RFID tag antenna is designed and fabricated based on the circular loop antenna used in the UHF band (Korea standard, 917 MHz to 923.5 MHz). The tag antenna size is reduced using a circular meander stub. The antenna has a physical size of 8 mm, which is about ${\lambda}$/40 in electrical length. The proposed tag antenna is molded into a medical sample and multitag identification is performed.

We designed and implemented a medical image query system, including a relational database and DBMS (database management system), which can visualize image data and can achieve spatial, attribute, and mixed queries. Image data used in querying can be visualized in slice, MPR(multi-planner reformat), volume rendering, and overlapping on the query system. To reduce spatial cost and processing time in the system. brain images are spatially clustered, by an adaptive Hilbert curve filling, encoded, and stored to its database without loss for spatial query. Because the query is often applied to small image regions of interest(ROI's), the technique provides higher compression rate and less processing time in the cases.

U-healthcare system supports healthcare service of prevention, diagnosis, medical treatment and currently various medical service systems. Therefore, utilization of medical information thru hospitals, medical agencies is unevitable in this society. However, the standard draft of HL7 which is a standard of medical information does not support specification of medical information being used currently. Thus, in this paper, we study standard HL7 message system to analyze and adjust the medical information and it will help to utilize efficient medical information and the method is verified to be sufficiently effective.

Recently, as elderly people suffering from chronic diseases have increased and disasters such as traffic accidents have increased, urgent rescue workers and doctors need to respond effectively to such emergencies. For elderly people, the difficulty in communicating their condition especially the health condition during disaster is one of the problems in which delay on immediate handling by rescue team can cause death. Providing a solution for this problem is one of the main issues in our research. In this paper, we use the QR code to communicate the minimum personal information and medical history needed for emergency medical treatment to emergency medical personnel, and to transmit the medical history and treatment data to the doctors of the hospital through QR code and fingerprint recognition, respectively. Especially, by using both QR code of smart phone and fingerprint of individual, we can protects personal information and strengthens privacy and security of medical information by allowing only authorized physicians to check medical records of the old patient.

Purpose : This study was conducted to understand the unforeseen phone calls placed through the 1339 emergency medical communication system by residents of the Gwangju/Jeonnam area during the Lunar New Year and Chuseok holidays. Methods : A descriptive research method was implemented using SPSS to analyze 9,047 reported and received consultation phone calls made during the 2008 Lunar New Year holiday (February 6-10) and the 2008 Chuseok holiday (September 13-15) for frequency and percentages. Results : Among the general characteristics of subjects during the Lunar New Year and Chuseok holidays, an examination of the distribution for gender showed more men than women and the distribution for age showed most subjects were thirties, followed by forties, and finally under ten years of age. According to the status of situational calls during the Lunar New Year holiday most were used for in the following order : providing resource information, misdialing and prank calls, and additional consultations. According to the status of situational calls during the Chuseok holiday most were used for in the following order : providing resource information, additional consultations, misdialing and prank calls. According to region most came from Gwangju Metropolitan City Bukgu, followed by Yeosu, Suncheon, and Mokpo in Jeonnam. According to callers, the majority were non-medical persons. According to time most were made between 9:01 and 12:00, while the fewest were made during 3:01 and 6:00. According to treatment department most were made in the following order : internal medicine, pharmacy, and pediatrics. Most medical resource information provided regarded areas outside the callers location. Conclusion : Emergency medical technician will play a central role in the emergency medical information system in the near future.

This paper presents a verification watermarking applied to healthcare information management. The proposed method uses the whole region based on the public-key cryptograph, which is transformed by the DWT transform to integrity verification. Furthermore, the public-key cryptograph algorithm is used for the embedded watermark image. We adaptively select the upper bit-plane including the LSB parts of each block when the watermark is inserted.
