KISTI portal service is currently presenting the documents with many terminologies, so users can't find the results having their intention by using an umbrella query. In this paper, we suggest user oriented retrieval service that reflects query auto-complete, related-word suggestion and query expansion that uses nouns and relationships of U-WIN which is known as a semantic language resource. We intend to advance the retrieval satisfaction of current science & technology information service by using U-WIN's semantic information and improve the service environment that user can retrieve what they want quickly and exactly.

This study aims to explore concepts of public interest and universal service which have been essential ideologies and policy goals, but which have been a the state of conceptual chaos so far. It sheds light upon three aspects : (1) the origins of public interest and universal service, (2) conceptual components of public interest and universal service, and (3) the implementation of public interest and universal service ideologies into policy. As a result of this analysis, it was found, firstly, that public interest of broadcasting originated from western countries, was rooted in the United States, and then spread all over the world later. After universal service was begun in the United States, it became a key ideology of information and telecommunication in European countries and other countries as well. Secondly, when examining the conceptual components, more differences were found than commonalities between these two concepts. The most conspicuous common point was universalism The concept of public interest includes not only universal service, but also connotes other components such as independence, diversity, quality, and locality which are related to content. Thirdly, when these two ideologies are implemented into policy, there Is a contrast. This study shows that the public interest ideology was realized into regulatory policies, while the universal service ideology was realized into supportive policies. In conclusion, this paper suggests more exact usage academically, showing the differences between the two concepts. This paper recommends an enforced legal duty of broadcasters to provide universal service when the current broadcasting law is revised.

With the advent of the 4th Industrial Revolution, the modern economy is transforming into a service-oriented economic society, and there is a growing need for companies to reorganize organizational culture, values, and human resources to suit the changing environment. Especially, even when times change, human capital is the most important factor in maintaining sustainable development and Corporate value, since all work is done by people. Therefore, in this study, in order to recognize the importance of human resources and verify the appropriate human resources for the changing service economy era, we reviewed the literature and that drew the human resources suitable for the recent service economy era Based on this, an empirical study was conducted on whether the suggested human resources factors were useful. To this end, a feasibility analysis, reliability analysis, correlation analysis, confirmatory factor analysis, and reference validity were conducted by dividing into a preliminary survey and a main survey. As a result, it was finally drawn with 30 items, 7 factors. The results of this study are expected to be used as basic data in various fields of research on human resources in the service economy era, and in-depth empirical studies are needed in the future.

The objective of this study is to provide faster mobile web service by improving performance of Contents Cache used for mobile web service in the existing Mobile Gate System. It was found that two elements existed in Mark-Up page transcoded by Contents Generator. One of the elements was dependent only on the requested DIDL page and Mark-Up type. The other was dependent on each of the requested DIDL page, Mark-Up type, size of mobile display 모바일 장치 to request service, type of images available and color depth count of the images available. The conventional Contents Cache saved the entire Mark-Up page to hold both of the two elements. This caused the problem where storage space was not effectively used because reusable elements were repetitively saved in cache memory domain due to change in one of the elements even though all the other elements were the same. As a result, a larger number of transcoded Mark-Up pages could not be saved in the same cache memory size. Therefore, in this study, Mark-Up pages transcoded by Contents Generator were divided into two elements and were separately saved. Also, in order to respond to the demand for replacing data in cache with new data, this study applied two algorithms of LFU and LRU. This study proposed the method to implement cache performance of faster speed by enabling to save more number of the transcoded Mark-Up pages in the same cache storage space.

As the ubiquitous technology has been widespread, the u-service development in the private sector is increasing these days. Especially, consisting of various life spaces, a mixed-use complex started actively utilizing the ubiquitous technology in order to provide users with differentiated services. In this paper, a new development methodology of the u-service for a mixed-use complex is proposed. Because the ultimate purpose of the u-service in a mixed-use complex is to guarantee profitability, the u-service must accelerate commercial activities among various users in the complex. The u-service development methodology of a mixed-use complex proposed in this paper firstly defines various perspectives for the u-service and identifies specific u-service elements in cross points of the perspectives. Then with those u-service elements, the methodology generates a u-service pool. Finally, after evaluation process, target u-serviced to develop are selected. Having designed the u-service development methodology, we expect the methodology to contribute the successful implementation of u-service model for a mixed-use complex.

Depending on point of view, a service can be defined as interactions between customers and service providers or service delivery processes or customer's experiences. To develop and design a new service, the most of approaches presented in the previous researches represent a service mainly by the interactive activities or functions between customers and providers. The critical features of services which differentiate services from physical products are the inseparability that production and consumption occur at the same time and the heterogeneity that each customer ask their requirements to providers. To reflect the characteristics on the service model, we have to include contextual features in the service model. For the purpose, we define a service as the process of solving the customer's problems and a service is structured into three components: contacts, informations, and activities. We suggest the job mapping diagram to model a service process by the three components and then apply it to a hotel service process and compare the result with it of a blueprint.

NGN is a packet-based converged network to support session and non-session services in QoS-enabled broadband transport network. QoS based resource control must be defined to support differentiated services for various network users in NGN. We designed and implemented DIAMETER protocol as the Rs interface, and also defined mapping rules between DIAMETER information elements and SDP(Session Description Protocol) attributes for QoS based resource control in NGN. We selected and implemented DIAMETER protocol among alternate resource control protocols in ITU-T as the Rw interface because of simple interworking method with Rs interface and adequate AAA functionality. We defined mapping rules of messages and information elements between Rs and Rw interfaces for resource control from a service layer to a transport layer. Based on the mapping rule of QoS information elements and the interworking method between Rs and Rw interfaces, we built up a test-bed that support differentiated delivery services.

The purpose of the study was to divide social commerce websites' information into components of product, price, service, and seller information, and to systematically analyze each component of information. A content analysis was used as a research methodology, and 100 webpages from social commerce websites were analyzed. As results, the social commerce websites provided basic information (front view, fabric contents, country of origin, care, color, size) for product information and emphasized price information, including discount rates, sales dues, product quantity, and the amount of products sold. They basically provided expected delivery date, delivery company, Q&A, and return/refund service for service information. In addition, they basically presented brand logo and brand name but need to add information about brand concepts, history and volume as seller information. This study suggested diverse theoretical and practical implications of social commerce information.
