This study aims to perform an evaluation of the book services and academic information services provided by the major search portals of Korea and the United States. This study also investigates the relationships between search portals and academic libraries. The results of this study can be implemented for the development and improvement of the portals' book and academic information services. Users can refer to the results of this study in choosing services from search portals. The results of this study can also provide implications for the differentiation of academic library services.

Increasingly, Grid technics are developed and demonstrated widely. These days, a point to be considered is that clients use Grid resources more easily. Grid Portals, based on standard Web technologies, are increasingly used to provide user interfaces for using Grid resources. But, due to lack of delegation capabilities in using Grid resources through Grid Portals, it is requested of the security mechanisms. That solution is to using Myproxy Server. Myproxy Server allows Grid user to use Grid resources being interact with Grid Portals. But, while users log in Grid Portals, we are faced with over the overlap of users credentials. This paper describes relationship between Portals and Myproxy, and proposes the way to solve the problem of the overlap of users credentials.

The study suggests an answer to the question of what determines category diversification of Internet portals in Korea. First, as external factors, competition intensity and market growth are hypothesized to have influence on the degree of category diversification. Second, an internal factor, user loyalty to portals, is hypothesized to influence negatively category diversification. The study performed empirical analysis based on weekly portal-specific panel data of eighteen internet portals in Korea during the period between 2001 and 2004. The result shows that category diversification increases as competition intensity increases, and that category diversification decreases as user loyalty increases. There was no effect of market-level growth rate on category diversification.

This study analyzes the legal reasoning of Seoul Central District Court, which imposed legal liability on portals for posting defamatory user replies to news articles, written and provided by the news media, onto their 'News Windows'. Saddling portals with the burden of verifying the facts associated in news articles and imposing the legal obligation as a publisher entail a grave risk of impairment of free flow of information and freedom of expression. Of course, it would ultimately result in tightening up private censorship of information which the Constitution does not allow, and funker keep portals from posting even news articles in which expressed views and opinions are lawful. When judging whether portals should assume liability fur libelous user replies to news articles, it is necessary to distinguish the territory under the direct authority of portals from cafes and bulletin boards managed by third parties. In addition, imposing legal liability above the level of common carrier should be limited to the cases; when portals arbitrarily change the contents of news articles or when the articles portals changed contain libelous contents. Even if those conditions are met, the altered contents should obviously constitute libel. Only in the presence of proof that portals knew the illegality of news articles and did not take proper steps including deleting those replies, should portals not be considered as an accomplice. Nor should portals take responsibility for users' defamatory replies for those reasons.

Internet portal is an entryway, the first page encountered before the user entered target sites. Despite tremendous interest in the proliferation of internet portals, there is little, if any, research that demonstrates developmental process of internet portals. This developmental process is important to the generation of critical mass for e-business. The objective of this research is to discuss the process and evolution of internet portals via qualitative research. In doing so, we present $2{\times}2$ matrix as determinant with analyzing how it impacts developmental process of internet portals and perform case study to demonstrate them. The result shows that First, all internet portals are have tried to link 4C and commercialization through developmental process. Second, community service is one of the most important ways to realize commercialization in electronic market.

This study aims to perform an evaluation of classification systems provided by major Korean search portals, Naver, Nate, Daum, and Yahoo-Korea. These classification systems are evaluated in terms of the consistency of classification system, logicality of classification system, ease of interface, clarity of category names, order of category and site listing, and hierarchical structure. The results of this study show that each search portal provides separate classification systems for their services. These results imply that it is crucial for search portals to implement a common classification system and a common interface for their services. This study could contribute to the development and improvement of portals' classification systems.

The objective of this study is to explore a knowledge sharing typology for Internet portals based on knowledge-based view of firm. Furthermore, we provide insights into how the evolution of Internet portals takes place by describing user behavior of knowledge sharing. For doing this, we first present a typology of knowledge sharing based on the two dimensions such as knowledge donation and knowledge collection. Then we conduct case study of the Korean major portals to demonstrate a proposed typology. The main finding of the analysis is that three distinctive types of knowledge sharing patterns within portals are distinguished: collaboration, accumulation, and publishing. We conclude that user behavior of knowledge sharing is characterized as guiding factors in evolution process.

The real estate portal has grown into a successful e-Business model that is combined on and off line. Although IT technologies have shown rapid growth, the real estate portals have failed to satisfy the expectations of the Internet users. Based on Michael Porter's competitive forces framework, this study proposes five competitive strategies for continuing growth of the real estate portals. First, to strengthen bargaining power against supplier, buyer and potential new entrants, the real estate portals need to construct a basic network that is cost efficient and maintains real estate goods and makes profits by collaborative deals. Second, strengthen brand value and endeavor to escape from dependency on the Internet portals. Third, develop services to consider changed circumstances and give a lot of sources to make profit to real estate agencies. Fourth, concentrate on marketing to draw in the Internet users and adapt strategies that have been successful in other fields. Finally, real estate fields can seek out ideas for developing new business models from other successful e-Business models and should benchmark them to reduce expenses to a minimum and increase benefits to a maximum.

Tunnel portals are often located in areas where the risk of rock fall and/or detachement of rock fragments from rocky slopes is high. In this case it is necessary to design the portals so as to protect the road (i.e. using an artificial tunnel) or to instal structures that are able to intercept falling blocks on the slope. This paper deals with the design problems of these structures and includes a special analysis of net fences which have undergone a remarkable technological improvement over recent years.
