In this paper, we propose a design and implementation of Home Network Middleware which offer integrated service of electronic products. Most senior nations setting to core paradigm to ubiquitous computing techniques and effort to get the novel information and making more power about information techniques. But, they don't have a skill to Home Network Middleware in electronic products. It is a more important in Home Network Middleware. So, we will try to study about Home Network Middleware skill. And suggest to proposition that is a novel Home Network Middleware.

This paper has studied a management system for RCST of the Satellite Multimedia Internet Service through analysing the architecture and specification of BSAN based on Digital Video Broadcasting System. In this paper, designing and implementing RCST DPM and agent system are shown. The UCD-SNMP framework served as base station for implementation of the agent. And the message protocol between RCST DPM and agent system has been also defined to provide a way for interaction.

This paper deals with a denial of service is about without permission knocking off service, for example through crashing the whole system. Another definition is that denial of service is seeing to that someone don't get what they paid for. The Network Denial of service Attack Detection System designed and implemented through suggested algorithm can detect attacking from the outside among denial of service attacks. It shown that designed system gives the system administrator the opportunity to detect denial of service attack.

We research and analyze to the IMT-2000, it contains the various problem with the bandwidth and standardization. Finally, we proposed to the method of the standardization and implementation for the Beyond IMT-2000, in this paper. Comparing the Beyond the IMT-2000 take advantage of the aspect of the GPS(global positioning system) service and remote medical treatment service and wireless internet service and VOD(Video on Demand) service with IMT-2000. Henceforth, we are consider to the development of the contents which it is adaptable to various environment.

The Phone Voting service allows subscribers to propose a voting through a telephone, and enables them to survey public opinion using telephone network. The demand on this service is growing faster and demands will be increased much more. It makes the bust traffic at the Toll SSP system on Intelligent Network because of the temporary bust traffic congestion on the Toll SSP compared to the normal call traffic. This paper will show what the problems and the causes are, and how we can solve them. The solution to these problems is an implementation of the SSP function on the Local Excange for the PV service.

In this paper we introduce a design and implementation of an agent for multimedia retrieval and personalized broadcasting service. It is compliant with TV Anytime Forum specifications and supports searching location resolving, storing and streaming of remote multimedia contents. For this service, we implemented a contents server, a 메타데이터 database server, a location resolution server and a client terminal is implemented The Client terminal gathers content information by SOAP of operation, and it has a user preference module and usage history module that make user information. The personalize service agent recommends suitable contents to user by similarity algorithm.

In this paper, we present a practical implementation of the MPEG-21 multimedia framework for broadcasting and communication convergent services. MPEG-21 standard technology was exploited to build a convergent service framework. Using this framework, a service model and several scenarios have been successfully designed and implemented. In addition, interoperability, which is the main objective of a multimedia framework, especially in a convergent environment consisting of heterogeneous networks and various types of devices, has been addressed in detail. The experimental results show that the implemented test bed provides a next-generation multimedia service; that is, universal multimedia access (UMA), meeting the requirements of a broadcasting and communication convergent environment.

Because shore(ship) to ship(shore) communication service via INMARSAT pay expensive cost, satellite service typically use two stage service that land users dial up LES(Land Earth Station) for sending or receiving message. In order to send and receive message, land users must maintain online state with LES on dedicated line. Also, two stage INMARSAT communication service must consume long time that processes step by step. In case of large company, they have own communication system, but small companys communicate simple messages with only telex. This paper describes the design and implementation of an integrated communication services via INMARSAT-C. This system uses inexpensive INMARSAT-C for transmission between ship and land. Because this system provides web and E-Mail interface, users send and receive messages easily and quickly. This system provides most users with inexpensive and easy communication facilities between ship and land.

Current communication and broadcasting services are moved to integrated convergence service. So IPTV(Internet Protocol based TeleVision) services are growth rapidly. Traditional TV were provide simplex service. but IPTV will provide duplex service that is possible of interaction with TV and audience. Therefore current researches are focusing the Social TV service. at this point, we see the trend of Social TV system for research and implementation.

The purpose of this study was to identify the determinants of nutrition service utilization in health centers. Utilization of nutrition services for chronic discase were also investigated. Interview survey using questionnaire was conducted to collect the data required for analysis. The study subjects were 300 residents over 40 years of age, and 15 health workers representing health center service personnel in Kypnggi province. A wilcoxon 2-sample test and Kruskal-Wallis test were used to compare the distribution of health centers by health center characteristics and nutrition services. A chi-square test was used to test the association between service utilization and personal variables of the population. A multiple logistic regression analysis was used to measure the relative importance between the variables on service utilization. The results showed that only 10.0% of the study subjects used nutrition services provided by the health centers. Pilot project implementation and location of health centers, as well as educational level of the residents were significant factors influencing the utilization of the nutrition services provided by the health centers. Among the variables, pilot project implementation was the most important factor that influenced the nutrition service utilization in health centers.
