Telematics, one of the so-called New Growth Engine of IT839, is a leading IT service where wireless internet service represented by information and mobility is extended to the area of transportations to provide Telematics service. The killer-application of Telematics is navigation system. Recently, due to the mass storage conversion, the performance of the terminal and mobile communications technology development, navigation system is also changed. It more and more develops into 3D in a preexistence 2D map. In the future, it is expected to include the remote sensing map. There is also the characteristic of all the information expressed in frequently a change partially happening. That is, POI(Point Of Interest) which is freshly registered or is deleted is many. In a preexistence, MCP(Map Contents Providers) offer the new version map by off-line monthly or quarterly. And a user wastes time and is inconvenient because of updating the total map by the off-line. Thus, in this paper, in order to resolve this, we describe MCP-MAUS(Maus Air Update Server) interface for updating only the partial map that was changed.

With the advancement of the industry such as information technology, residential facilities has been consistently achieved high standard. Ubiquitous system has been introduced in apartments nowadays, and it will be general facilities in the near future. However elderly people is not generally accustomed to ubiquitous or internet environment, so degree of ubiquitous system usage is able to be less than young people. This study aims to grasp the relative importance of ubiquitous environment, and offer materials to realize residential environment's improvement of silver towns under investigation through a questionnaire survey. Skin recognition system was most preferred among various functions. Energy management system, protection system of solitude elderly person and security system by CCTV was also preferred at a high rate. Housework part such as cooking aid, height control of sink and basin etc., was not less important system relatively.

The Photovoltaic(PV) generation system is a promising source of energy for the future. Since the need for renewable energy has been increased, the research of PV generation system has also been progressed. The main subject of this paper is about making the more useful real-time monitoring program to get and save the data from photovoltaic generation system of 30kW grid-connected. Therefore, it uses LabView for this real-time monitoring program.

Since the 21st century, to the worldwide computer, broadcasting, communications and other technologies have be developed. because of the Internet allows real-time information delivery, Information Society that was done quickly. In this study, using information technology, Active measures to enable e-commerce in agriculture is discussed. agricultural e-commerce to the consumer satisfaction surveys were conducted, too. In addition to, as a e-commerce features, informance, convenience, interface presented. After research results, I think information, convenience, interface is important to consumers. Consumers will be spent on activities having a new value. To respond to these consumers, Companies must evaluate the internal capabilities. and outside the assessment continuously. E-commerce will give an effective way to companies. And e-commerce will develop further in the future. Therefore, e-commerce will be done by the long-term plan.

Ultimately, this research will focus on the activity traits of future customers in the convergence age. To accomplish that, firstly, researcher develop measures for assessing the convergence level of digital devices and digital services. Next, this will investigate the behavioral traits of people who use specific devices or services on the internet or mobile networks. This study proposed five convergence measures each for devices and services. For digital devices, measures such as converged functions, accessibility to network, portability, immediate communicability, and expandibility of functions were utilized. For digital measures such as scope of users, newness, social network level, ease-of use on mobile networks, and expandibility of information were used. We believe that the research results can provide insights for those wishing to explore the convergence level of devices and services and those developing high-level converged devices and digital services.

Document retrieval (DR) has been a serious issue for long in the field of Office Information Management. Nowadays, our daily work is becoming heavily dependent on the usage of information collected from the internet, and the DR methods on the Web has become an important issue which is studied more than any other topic by many researchers. The main purpose of this study is to develop a model to manage business documents by integrating three major methodologies used in the field of electronic library and information retrieval: Metadata, Thesaurus, and Index/Reversed Index. In addition, we have added a new concept of eDocument, which consists of metadata about unit documents and/or unit document themselves. eDocument is introduced as a way to utilize existing document sources. The core concepts and structures of the model were introduced, and the architecture of the eDocument management system has been proposed. Test (simulation) result of the model and the direction for the future studies were also mentioned.

Today’s information technology departments face a dilemma to create a competitive advantage for the organization by developing. deploying, and managing distributed applications that scale across the LAN, WAN, and Internet, while preserving investments in systems. Applications, information. IT organizations are today being asked to build the future, without breaking systems that maintain the current business. A possible answer to this dilemma is the implementation of a multi-tier distributed computing architecture. Multi-tier architecture has the potential to provide better, more timely information across the enterprise at a lower cost than the current combination of PC LAN, two-tier client/server, or mainframe applications that have been developed in most organizations. In this paper, we implement management information system based on distributed object middleware using multi-tier distributed computing architecture. This system uses Microsoft's implementation of DCOM/ActiveX and provides easily accessible web interface to the system users.

This research examines 13 Korean Web sites and 15 foreign Web Sites to explore how companies present apparel products by both layout of graphics and information at the Web sites. The results show that most Web sites display tiny icons next to the item's text description. Clicking on these icons takes the customers to another web page, where the full size photograph of the item appears. The results also revealed that most web sites offer shopping bag function and payment options such as on-line and credit cards. The results indicate that Web sites are constantly evolving and following functions such as virtual dressing room, FAQ, the links, E-Cash payment, currency converter and multilingual sites are becoming standards in the near future.
