As Ubiquitous era comes, it became necessary to construct environment which can provide more useful information to human in the spaces where people live like homes or offices. On this account, network of the peripheral devices of Ubiquitous should constitute efficiently. For it, this paper researched human pattern by classified motion recognition using sensors module data. (This data processing by Neural network and fuzzy algorithm.) This pattern classification can help control home network system communication. I suggest the system which can control home network system more easily through patterned movement, and control Ubiquitous environment by grasp human's movement and condition.

As the research activities related to 'Ubiquitous Computing' whose concept was introduced by Mark Weiser are growing, RFID(Radio Frequency Identification) technology has recently gained attention as a technology to advance the ubiquitous computing and a lot of related researches are also in progress. Research works done so far are mainly linked to the situation that the research outputs apply to meet the requirements for asset tracking and data sharing with partners over supply chain by using fixed RFID readers. However, it is essential that users have access to real-time information about the tagged objects and services whenever and wherever they want in the era of ubiquitous computing, so mobile devices-including PDA, smart phone, cellular phone, etc - which are equipped with an RFID reader can be regarded as an essential terminal for users living in ubiquitous computing environment. As far as the application with mobile devices are concerned, there are many considerations due to their limited capabilities of data processing, battery consumption and so on. In this paper, we review the generic RFID network model and introduce the revised RFID network model in consideration of incorporation with mobile devices equipped with an RFID reader. Also, we derive the requirements for software embedded within an RFID- enabled mobile terminal and then discuss essential components for implementation. Moreover, we develop the applications for asset management at museum by using mobile RFID network model.

Thanks to the recent rapid development of the Internet, we can access networks whenever we like and wherever we are. This development allows access to desired information on a truly global scale. This thesis investigates the case of Diet Contents to use the mobile service in the era of Ubiquitous Computing. Also this study suggests foundations for the development of more varied and effective mobile contents, which can provide audio and video information as well as simple text information.

The opening of ubiquitous computing era prompted rapid increase in information transfer between human and computer. Such changes in computing environment requires new computing interface. In this paper, we develop a user interface prototype and framework using Avatar in Ubiquitous computing environment, which can support an active communication between human and computer based on context information. To develop the new interface, its conceptual framework with specific context information is designed in advance. In addition, this study suggests the future goal of user interface using Avatar by suggesting the requirements of constructed prototype.

It is only 2 ~ 3 years in the interior to be introduced as a Ubiquitous era after going through mainframe, PC and internet era on account of the advent of computer. This thesis intends to present a model device of an epoch-making cash management system using the RFID(Radio Frequency Identification) Tag and EPC (Electronic Product Code) Platform which are core technologies of the Ubiquitous Computing on the assumption that cable and wireless internet is constructed in university. Also this sets up a purpose to minimize the administrative procedure as well as the waste of time, people and cost which are problems of the cash management system operating now. Therefore as a research project hereafter, it will be able to present an imporvement device about the problems which cannot solve these days through the model of the proposing cash management system when the standardization, normalization and commercialization of advanced IT department are accomplished.

There are some technologies such as USN, RFID, Home-network to advance the ubiquitous era. Those technologies embody Context-Awareness System. To Context-Awareness System is that human, objects and environment supply information with cable and wireless at real time. So private information, information privacy, a wide sense privacy will be faced on serious menace. In this article, I analyze threat of private information in Context-Awareness System under USN(ubiquitous Sensing Network) surroundings and present technology to protect private information. Each technology can apply subdivided protection province information privacy. I expect definition of information privacy, insight through technological presentation and total solution in this article.

Since the beginning of the 21st century, the power source for the growth of our country is shifting from the 'knowledge and information'-centered business to the culture-based business attaching importance to 'creativity'. In the era of creative culture-based economy, the core resources on which the national competitive power depends can be thought to be 'cultural contents'. The current ubiquitous project, which is being promoted in our country, is characteristically placing much emphasis on building-up of the RFID-centered infrastructure so that it is poorly acknowledged by common people to whom its service is actually provided. In this study, the approach to promotion of the cultural service, to which an easy access is available as a result of combining the ubiquitous-based technology with 'cultural contents', is discussed in the 4 aspects.

We are entering into a era of enterprise computing that is characterized by an emphasis on broadband convergence, knowledge s haring, and calm services. Some people refer to this as the "ubiquitous" computing because its focus is on a high degree of connectivity between a company and its customers, suppliers, and channel partners. Ubiquitous computing technology, "RF" stands for "radio frequency"; the "ID" means "identifer". The tag itself of a computer chip and an antenna. The shortest metaphor is that RFID is like a bar-code but is read with an electromagnetic field rather than by a laser beam. Much has already been written about the use of RFID. But there is no has written about the use of RFID in the convention industry. Therefore this study have specific objectives as follows. 1. To give details on the use of RFID in convention. 2. To introduces the key concepts behind RFID technology. 3. To identify advantage & disadvantage of RFID technology using a BEXCO CASE study. 4. To study on ubiquitous convention using RFID and effective operation methods such as entrance identification system, session management, machine management, CRM management, visitor management, and contents management. This results provide into the current status of ubiquitous computing technology in convention industries. Specific advantages by using ubiquitous computing technology(RFID) are one-stop differentiate service, wireless internet service, use of visitor management system, entrance by tag, and U-logistics. On other side, disadvantages are security, stabilization of RFID system, higher price of RFID tag, and commercial scale. Convention by using of RFID technology is currently at an early stage. Convention company as BEXCO need to have the capabilities to adapt, to customize, to commercialize, and to modify technology to suit our circumstances.

In recent years, our society, because of the arrival of a new paradigm according to the rapid changes in ICT has entered into future smart society and the ubiquitous era. So it can be a notable turning point in the city and administrative spatial informatization, aspects of the era change. Therefore, this study was to derive a desirable vision for the city of Busan Centum City Informatization in the dream of leading global smart city of Busan by applying 'scenario planning' as a foresight method. Soon this study derived a successful local informatization strategy for Centum City in Busan. It proposed the use of the administrative aspects of information with spatial informatization as metadata information. Also this study explored the future leadership strategy of Busan Centum City in smart society. Eventually in 2030 to around, In order to still remain Busan Centum City as a leading ICT smart city, this study suggested the following strategy. It is important to increase the satisfaction of citizen services through the use of the administrative aspects of information with spatial informatization as metadata information for urban information system.
