Although searching service is popularized in the PC-based internet environment, it is not (or rarely) supported on TV, which is the major multimedia equipment in the living room. Several trials are made to port established PC-based searching systems onto TV-set but failed to get popularity among viewers as they did not consider the viewers' modality. Operating the searching system should not disturb viewers in watching TV (for example, TV screen should not be (even partially) covered by the searching system's graphics) and the number of pushing the remote controller's buttons should be minimized so that viewers can keep watching TV without glancing at the searching system's graphics. In this paper, the author introduces a new searching system running on TV-set, which is designed to reflect properly the viewers' modality. The searching system is also compatible with the data service standard adopted by the domestic broadcasting networks so that it can be easily implemented by them.

As the representative of the convergence of broadcasting and communication, the data service was expected to be a new profit source of the related industries. The data service, however, has not satisfied the expectation due to the short of killer services that make it popular with the viewers. According to the several survey reports, a lot of viewers do internet-searching using the key-words related to the TV program they are watching and, with the faith in the survey results, several trials has been performed to port established PC-based searching systems onto TV-set only to fail to get popularity among viewers. The failures are mainly caused that they did not sufficiently consider the viewers' modality that viewers seriously want not to be obstructed by anything when they are absorbed in a program. This paper proposes an MHP-based searching data service designed to minimally interrupt the viewers watching a TV program and to be synchronized with a TV program by using the searching key-words relative to it, the content of which changes as time goes on.

Spatial information has recently been recognized as one of the major subjects of interest in information technology. With increasing variety and quantity of spatial data on the web, searching and maintaining these data are becoming a much focussed area of research. Interoperability is the key technology in solving the complexities of spatial data in web services. The problem of maintenance and searching of spatial data in an interoperable web service environment can be solved by establishing standardized metadata of spatial information. Then using the standardized metadata, catalog web services can be deployed for autonomous searching and binding of spatial data. This study investigates the international standard for spatial data metadata(ISO/TC211 19115) and deployed catalog web service based on this metadata. Various heterogeneous spatial data of Seoul Metropolitan region were then used for experimental implementation of catalog web service.

This study investigated the differences in the importance of store characteristics depending on on-line clothing store type and consumer age. The questionnaires were given to female residents in the ages between 20-39 in Seoul and Kyung-gi province during October 2006. The results were summarized as follows: 1. By analyzing the differences in importances of on-line store characteristics factors it was found that buying process service factor and product searching system factor were important in on-line general merchandise store. and buying process service factor and product factor(all the factors, such as store credit, product, screen-displayed design, searching and approaching system, customer management service) were important in on-line specialty store. 2. By analyzing the differences in importances of on-line store characteristics depending on the store type, buying process system such as refund policy, shipping, high-speed payment and rapid searching, screen-displayed design system, approaching and searching system were more important in on-line general merchandise store when comparing to specialty store. It also showed that the consumer considered the reputation of the store and its image more important in on-line general merchandise store. 3. By analyzing the differences in of on-line clothing store importance depending on age, in the case of on-line general merchandise store, it showed that people in their thirties regarded buying process service factor more important than twenties, and when it came to the product and searching system, it was vice versa. Twenties had a tendency to consider the aspect of product important and, relatively, thirties regarded searching and approaching system factor important. in the case of specialty store. It was found that women in their twenties had a tendency to consider product factor more important.

The Distribution System consist of many tie-line switches and sectionalizing switches, operated a radial type. When an outage occurs in Distribution System, outage areas are isolated by system switches, has to restored as soon as possible. At this time, system operator have to get a information about network topology for service restoration of outage areas. Therefore, the searching result of restorative topology has to fast computation time and reliable result topology for to restore a electric service to outage areas, equal to optimal switching operation problem. So, the problem can be defined as combinatorial optimization problem. The service restoration problem is so important problem which have outage area minimization, outage loss minimization. Many researcher is applying to the service restoration problem with various techniques. In this paper, advanced Dijkstra algorithm is applied to searching a restoration topology, is so efficient to searching a shortest path in graph type network. Additionally, fuzzy rules and operator are applied to overcome a fuzziness of correlation with input data. The present technique has superior results which are fast computation time and searching results than previous researches, demonstrated by example distribution model system which has 3 feeders, 26 buses. For a application capability to real distribution system, additionally demonstrated by real distribution system of KEPCO(Korea Electric Power Corporation) which has 8 feeders and 140 buses.

Objective : The purpose of this study is 1) to understand the information-searching behavior of health care consumers ; 2) to examine the relationship between the information-searching behavior of health-care consumers and regulatory variables such as socioeconomic factors, characteristics of medical utilization, and perceived risks ; and 3) to determine the factors that affect consumer satisfaction, especially with respect to information-searching behavior. Method : The data for this study were collected from 838 respondents in five university hospital located in three areas?Seoul, Gyeonggi province, and Chungchong province. As the first step of the study, we conducted a preliminary survey from September 23?26, 2008. At the second step, we conducted a survey on the effect of information-searching behavior on those individuals who had visited. Furthermore, personal interviews were conducted through a face-to-face survey between September 30 and October 17, 2008. Results : The major research findings that were obtained from the study were as follows : First, the age, educational level, and residential district were associated with information source utilization. Second, the level of information searching effort and quality of service had a significant effect on consumer satisfaction. Conclusion : These results show that it is essential for marketers to have in-depth knowledge about the young and educated people who actively search for information and about those who are in the prime of their life and rely on word-of-mouth communication from personal and experi in-al informers. Therefore, marketers should develop different marketing strategies to meet the needs of such consumers.

In the traditional Server/Client architecture, the client connects to the known servers and gets information through web searching. However, nowadays, diverse internet devices providing services (get) working on internet easily. The update interval of the services or information provided by the devices is relatively short. And also they tend to be both a server and a client. In this situation, the way of the traditional information searching such as web searching is not appropriate. In this paper we propose a service push model, where it pushes its service profiles to all the other network devices by broadcasting them on the network. When a device connects to the network newly, it can get all service profiles in the network and it gets service profiles newly pushed by service providers in prompt. Also it can call any service among the service profiles within itself. We implemented a prototype system for the service push model on the JXTA platform based on P2P network. Also we measured the service profile pushing delay, the service discovery time, and the response time of service execution by running test applications written on the prototype system.

Web Service which consists of SOAP, WSDL and UDDI is a software system that enables interactions of heterogeneous systems on networks with standardized XML message. Especially, UDDI is a registry for supporting the registration of a service by service publisher and discovery of a service by service requester. The preliminary studies are just about publishing and searching services. It presents the researches about UDDI study for improvement of searching a service and extended UDDI design for improvement of reusability with service components aspects. In this paper, we suggest not only features about publishing and searching services of existing UDDI system but also novel UDDI data structures and API for a reusable service model. In addition, we design and implement an extended UDDI system for publishing and finding the reusable services. Therefore, by using proposed UDDI systems, service developers reduce development costs and time through developing a service application reusing the already implemented services. In addition, it can expect to ensure the quality of services by reusing the proven services.
