The trend of the rapid development of IT promises to rapidly shift the existing IT world into one of ubiquitous computing where services using any devices are available anywhere and anytime. Ubiquitous computing as a new technology will profoundly alter the structure and behavior of industries, societies and cultures in the near future. The present technology does not permit completely ubiquitous computing. So advanced countries, except for a few, have focused their research onto building infrastructures and developing and deploying services first rather than building ubiquitous computing by a master plan. Korea, for its part in the development of the ubiquitous environment, is still on the starting line.
The reasons that we should construct an ubiquitous society are as follows. First, ubiquitous computing will have a huge effect on the domestic and global IT industry, which will lead the next generation technology. Secondly, korea needs to find new technologies and services to kick-start its stagnant IT industry. Ubiquitous computing is a potential alternative to supporting new industries and new markets.
The recent medical treatment guidelines and the development of information technology make hospitals reduce the expense in surrounding environment and it requires improving the quality of medical treatment of the hospital. That is, with the new guidelines and technology, hospital business escapes simple fee calculation and insurance claim center.
Moreover, MIS(Medical Information system), PACS(Picture Archiving Communication system), EMR(Electronic Medical Record) are also developing. MIS is evolved toward integration of medical IT and situation with increasing high speed in the ICT convergence. These changes and development of ubiquitous environment require fundamental change of MIS. Mobile MIS refers to construct wireless system of hospital which has constructed in existing environment. Through RFID development in existing system, anyone can log on easily to internet whenever and wherever.
This paper provides a basic review of RFID model and suggests the evolution direction for further advanced RFID application services. This paper implemented RFID database server, client PDA, mobile web server for WLAN, tag manager program, user's program. In this paper's RFID database, tag system modified patient tag that allocated patient information server(tag uid, name, password) in instant network. Using RFID 13.56MHz kit, embodies RFID system that makes possible to search and update the tag data of database that makes possible to link with client PDA program in MIS. In addition, designed and implemented medical examination support components and client program of mobile application that recognized RFID tag and patient data in the ubiquitous environments. This components implemented medical information system that performed patient data based PACS database environments, and so reduced delay time of requisition, medical treatment, lab.
