Web page evaluation is important issue in the Internet. Web pages are increasing extremely fast. The web page evaluation based on frequency, like the count of the page view (PV), is not sufficient way even it is used variously. Because users never use the unnecessary or irrelevant web pages for a long time. We concentrated on user's visiting duration time for the evaluation web pages. And we can collect user actions. Users do some action when users using the web page in the web browser. The movements of mouse pointer, mouse button click, page scrolling and so on are produced in the web browser. JavaScript can collect user action and Ajax can send collected data to server when user using the web browser without no user notification.

People are experiencing severe navigation problems in mobile site Relatively limited research, however, has been conducted on mobile site navigation compared to web site navigation. This research aims to identify efficient mobile site navigation aids for timely preferred contents. It proposed timely menu system based on statistic data, and evaluates its efficiency through commercial beta test. We conducted a beta test in the fourth quarter of the year 2007. The total number of user is 12,000. The average number of PV (page view) by the experimental group was increased to 10% more than control group. Our results indicate that timely menu system helps people navigate mobile menu system more effectively.

The purpose of this study was to look into the marketing strategies of social commerce companies by analyzing the relationships among the environment, strategy and performance in social commerce. For that, the environment condition and components of marketing strategy were derived based on the marketing mix by analyzing the related contents published in 3,783 articles on newspapers dated from April 2010 to March 2013. UV(Unique Visitor) and PV(Page View) for each social commerce site were used as surrogates for performance. The results of study revealed the relationship of the marketing strategies to the changes in environment conditions towards negative conditions such as the spread of buyer anxiety. In the "strategy-performance" relations, the product element and external sales promotion element had high correlation with the performance. Finally, a difference was found in the marketing strategies of social commerce companies. High correlation was found in all aspects between the UV and PV marketing elements in the case of Coupang, while the correlation with the UV was low and the environment also showed relatively low correlation level in the case of WEmakePRICE. Thus, this study is considered to provide useful basis for the social commerce companies to map out and implement the marketing strategies, and is significant in that it applied the marketing mix to the special market environment such as social marketing.

Nowadays an increasing number of Internet users are running individual websites as Blog or Cyworld. As this type of personal media has a great influence on communication among people, business comes to care about Network Effect, Network Software, and Social Network. For instance, Cyworld created the web service called 'Minihompy' for individual web-logs, and acquired 2.4milion users in 2007. Although many people assumed that the popularity of Minihompy, or Blog would be a passing fad, Cyworld has improved its service, and expanded its Network with various contents. This kind of expansion reflects survival efforts from infinite competitions among ISPs (Internet Service Provider) with focus on enhancing usability to users. However, Cyworld's Network Effect is gradually diminished in these days. Both of low production cost of service vendors and the low searching/conversing costs of users combine to make ISPs hard to keep their market share sustainable. To overcome this lackluster trend, Cyworld has adopted new strategies and try to lock their users in their service. Various efforts to improve the continuance and expansion of Network effect remain unclear and uncertain. If we understand beforehand how a service would improve Network effect, and which service could bring more effect, ISPs can get substantial help in launching their new business strategy. Regardless many diverse ideas to increase their user's duration online ISPs cannot guarantee 'how the new service strategies will end up in profitability. Therefore, this research studies about Network effect of Cyworld's 'Minihompy' using System-Dynamics method which could analyze dynamic relation between users and ISPs. Furthermore, the research aims to predict changes of Network Effect based on the strategy of new service. 'Page View' and 'Duration Time' can be enhanced for the short tenn because they enhance the service functionality. However, these services cannot increase the Network in the long-run. Limitations of this research include that we predict the future merely based on the limited data. We also limit the independent variables over Network Effect only to the following two issues: Increasing the number of users and increasing the Service Functionality. Despite of some limitations, this study perhaps gives some insights to the policy makers or others facing the stiff competition in the network business.
