This research paper delved into the availability and utilization of library portal services for research in university libraries in Nigeria. Two research questions and two null hypotheses were formulated to guide the study. A structured questionnaire was used for data collection. The study was carried out in Nnamdi Azikiwe Library, University of Nigeria Nsukka (UNN) and Felix Aghagbo Nwako Library, Nnamdi Azikiwe University Library (UNIZIK), Awka. A total of 70 professionals (librarians and system analysts) in these libraries supplied data for the study. Data collected was analyzed using mean and standard deviation. These were used to answer the research questions while the null hypotheses were tested using t-test statistic at 0.05 level of significance and 68 degree of freedom. Major findings showed that portal services available in the library showed that the areas of availability of library portal services in Nnamdi Azikiwe Library, U.N.N. includes Agriculture, Health Sciences, Engineering, Environmental Sciences and information about institution, Social Sciences, Arts and Humanities, Natural Sciences. In Festus Aghagbo Nwako Library, Awka, the areas of Portal Library Services include Career Development, Federal Government Programs, Environmental Sciences, Biological Sciences, Social Sciences, Arts and Humanities, Engineering, and Health Sciences. Findings on extent of utilization of portal services available in the libraries indicated that portal services are utilized to a low extent in the university libraries. Furthermore, librarians did not significantly differ in their opinions on the availability of library portal services and on the extent of utilization of library portal services in the libraries under study. It is therefore recommended that provisions should be made by the universities and library management to provide and update required portal services in addition to creating enabling environment for enhanced access and utilization of these services. The governments must make an effort to provide funds for policy implementation, necessary technology training for librarians and users, and develop general information infrastructure.

정보기술과 정보환경의 변화에 따라 인터넷 상에서 필요한 정보를 종합적으로 제공하는 포털서비스가 점점 일상화, 대중화 되어가고 있는 현실에서 정보의 제공과 유통을 담당하는 도서관이 포털서비스를 제공하는 것은 지극히 당연한 일이다. 이에 본 연구는 도서관 포털서비스의 이해를 높이기 위하여 국가디지털도서관인 디브러리 포털서비스를 메인포털, 지역정보, 정책정보, 다문화정보, 장애인정보, 디브러리 블로그로 나누어 그 구성과 콘텐츠를 조사 분석하였다. 그 결과 디브러리 포털서비스를 더욱 확산시키고 활성화하기 위해서 제공되는 디브러리 포털서비스의 최신성, 정확성, 유용성과 이용용이성, 홍보와 진흥 등이 강조되었다.

Portal sites have been providing diverse services to attract new users and retain existing customers. Recently, they also added new services and increased quality of the services they provide to secure more customers. It is, however, not clear how people actually react to such activities. We wanted to understand the mechanism associated with users' continued usage intention of current Portal site. We assumed search, e-mail, information, community, e-commerce services as key services provided by most Portal sites and considered valuable by many customers. The quality of these services may directly affect users' continued usage intention. However, we can also assume that attractive alternatives and switching cost may have some influence on users' continued usage intention. Therefore, in this study, key variables pertaining to the quality of key services provided by Portal sites, attractive alternatives, and switching cost were examined to explain the dynamics of users' continued usage intention. An empirical study based on 891 survey responses showed the importance of the quality of key services for users' continued usage intention. Switching cost also demonstrated strong association with users' continued usage intention. However, attractive alternatives did not show a significant association with users' continued usage intention. We also found that the variable attractive alternatives moderated the relationship between the quality of search service and users' continued usage intention and the relationship between the quality of information service and users' continued usage intention. On the other hand, the variable switching cost showed a moderating effect on the relationship between the quality of e-mail service and users' continued usage intention and the relationship between the quality of community service and users' continued usage intention. This study implies that Portal sites need to make efforts not only to improve the quality of key services but also to consider attractiveness of other Portal sites' services and switching cost to secure more customers.

In this paper, we introduce a mathematical model to analyze pricing/quality and service mix strategies for Internet Portal site. This model includes utilities and costs of each participants, i.e., user, third party provider, and portal sites. Especially, we consider portal sites that initiate their businesses by providing free services like free e-mail service or search service and providing several charged services. As the results, we can find that Portal sites should make the target of customers and focus them to maximize their profit. Portal sites should pay their marketing effort not for all customers but pertinent portions of customers. And Portal sites should make more efforts to efficiently develop and provision their services.

As the Internet service is expanding rapidly, portal sites, a gateway tn the net, are attracting increasing attention these days. As the Internet service has expanded rapidly, so has the interest for portal sites,, which serve as a gateway to the net. Despite the tendency, however, research on a measure by which to evaluate the quality of portal sites or development of such measures has not been fully pursued. As online services, faced with profitability, are considering 'charge per view', the development of a set of quality evaluation measures for portal services will prove to become a valuable instrument in constructing competitive strategies that are vital for survival and growth of a firm. In that regard, this study aims to develop a set of evaluation measures for Internet portal sites by empirically investigating the most common offline measures for quality of services, SERVQUAL, retail SERVQUAL and other evaluation measures for IT-related online services. Moreover, the study offers the strategic implications of the defined measures.

우리나라 온라인 저널리즘 지형의 과거, 현재, 미래는 무엇보다 포털 뉴스서비스와 밀접한 연관이 있다. 전통 저널리즘에서 한정된 뉴스미디어는 뉴스 생산과 유통을 동시에 수행하기 때문에 소비를 완전히 장악할 수 있었다. 이후 다매체다채널 시대에는 뉴스미디어가 큰 폭으로 증가하고 이에 따라 뉴스 생산이 폭발적으로 늘어나면서 수용자의 선택이 중요하게 됐다. 온라인 저널리즘 환경에서는 각종 뉴스 이용을 간편하게 만든 포털 뉴스서비스에 대한 이용의 집중, 뉴스미디어 브랜드보다는 뉴스 콘텐츠에 집중하는 뉴스 소비의 특성 등으로 인해 뉴스 유통이 가장 중요한 영역으로 부각됐다. 포털 뉴스서비스가 온라인 저널리즘의 상징적 존재가 되면서 뉴스 유통 중심의 우리나라 저널리즘 지형이 완성된 것이다. 뉴스 유통만을 담당하는 포털 뉴스서비스가 뉴스를 생산하는 언론사닷컴이나 인터넷신문보다 더 큰 영향력을 가진다는 것은 언론 권력의 변화를 의미한다. 이로 인해 기존 뉴스미디어와 포털 뉴스서비스의 갈등이 곳곳에서 목격된다.
