디렉토리, 포틀(portals), 게이트웨이, 네비게이션 서비스, 이러한 명칭처럼 웹사이트에는 매주 새로운 것이 등장하고 있다. 모든 대형 회사들은 자신의 사이트를 직접 개설하거나 사이트의 한 구획을 사용하고 있다. 왜많은 기업들이 자신의 사이트를 가지려고 하겠는가? 1994년 스탠포드 대학 전자공학부에서 박사과정을 공부하던 두 사람이 인터넷상에서 자신들이 개인적으로 관심을 가졌던 것들의 경로를 기록하기 시작했기 때문이다. 이들의 목록은 Yahoo!(야후, Yet Another Hierarchical Officious Oracle)로 성장했다.

The most widely used information searching method in the current internet environment is the keyword-based one, which has certain limitations in terms of precision and recall. Most major internet portals provide directory-based searching as a means to complement these limitations. However, that they adopt different classification schemes brings significant inconvenience to the users, and it consequently suggests a need to develop mapping gateway to provide cross-portal, or cross-directory information searching. In this context, this study attempts to develop a prototype system of intermediary gateway for integrated search, using the directory services of three major portals, Naver, Yahoo and Empas, and test its performance.

This study examines the current state of library related data opened through public data portals, and analyzes how much data is being utilized according to the type of releasing organization, and open level. In addition, we analyzed the subject cluster of data and the centrality of data by performing PathFinder Network analysis using keywords assigned to data by dividing the releasing subject into local government and national/public institutions. Based on this, the subject area of library - related data disclosed by local governments and national/public organizations is understood. And identify the main open body that should be opened first by linking with data utilization analysis result and then suggest implications for future improvement in connection with library big data business.

This study suggests evaluation criteria for the web-based question-answer databases provided by major Korean search portals. In particular, this study suggests evaluation criteria for the relevance of question titles, entire questions, and answer's. The evaluation criteria for the qualify of answers are also developed. Based on these criteria. evaluation of documents from Naver Knowledge-in are performed. The results of this study can be implemented to the development of test collection of question-answer databases. The implications for system designers and web content providers are discussed.

The purpose of this research is to propose a powerful alternative in designing knowledge portals using Topic Maps(TM). To demonstrate the power of TM In constructing knowledge portals. we designed a TM-based korean folk music(pansori) site, tested It with an existing pansoree site (pansoree.com ) employing diverse query patterns : simple, advanced, associative, and cross referential Queries. The results show that the TM-based site outperforms the pansoree.com in searching time and steps. The TM-based site also provide novice users who do not know pansori domain with easy access to Information that they need.

This study aims to investigate current status of mobile search services of Korean search portals, and analyze mobile unified search contents of Naver and Google Korea. In particular, this study analyzed characteristics of mobile unified search such as number of retrieved documents, collection distribution, and yearly distribution. Also, documents were evaluated in terms of relevance, credibility, and currency. This study compared quality of Naver's unified Web best and unified Web, and Google's best Web documents and Web documents. The correlation between document's ranking and document's relevance was analyzed. The results of this study can be implemented to the portal's effective development of mobile search service.

In the internet portal industry, the indirect network externality from portal visitors to advertisers and the direct network externality among portal visitors have important implications for anti-trust policies. This paper examines the existence and the magnitude of the direct/indirect network externality in the Korean internet portal industry and measures its effect on the market power of the internet portals. The results show that the direct/indirect network externality is substantive in the industry hence the market share of a portal in the visitors' side has the 'leverage' effect on its market power in the advertisers' side.

As the topography of Korea consists of mountains at about seventy percent, there is necessarily an increasing demand for tunnel construction according to the expansion of the existing highway and construction of new highway. The concrete lining of tunnel portals has been designed with reinforced concrete to resist the cracking due to the difference in temperature in the inside and outside of tunnel. In the paper, the application of steel fiber reinforcement concrete was analyzed as the lining concrete at tunnel portals and through structure analysis and field model test the suitability of the steel fiber reinforcement concrete was assessed as the lining member of tunnel portal.

Self-care to prevent cancer and self-management to cope with the disease are two discrete effective mechanisms for improving of control and management of neoplasia. Both them have certain strategies and practices. Often the two are used interchangeably despite their different approaches. Strategies of self-care usually refer to prevention at different levels include primary, secondary and tertiary. In contrast, strategies of self-management are related to management and alleviation of unpleasant cancer-related symptoms and treatment-related side effects for improving the quality of life of cancer survivors. Successful promoting of self-care and self-management strategies need people and survivor empowerment. Within this context, innovative approaches open a new window. In this paper after a brief review of related strategies and practices, we provide an explanation of how cancer portals may play an important role in the empowerment process and what are key potentials for implementing of self-care and self-management strategies for cancer.

Trans-posterior septal posterior arthroscopic portals are useful in performing arthroscopic diagnosis and treatment of the lesions located in posterior aspect of knee joints. Except inferior surface of posterior horn of lateral meniscus, we easily observed entire lateral compartment, especially inferior surface of anterior horn and lateral tibial condyle by figure of 4 position through posteromedial trans-posterior septal arthroscopic portal. And it was possible to obtain visual field from posterior aspect and we could use anteromedial and anterolateral portals for instrumentation without clouding. So, this procedure may be useful in performing surgery of lateral compartment especially, anterior aspect in the knee joints.
