We compared nanotechnology web portal requirements using a Kano method, to identify similarities and dissimilarities in Kano-categorizations of features and functions required of nanotechnology among users in universities, government research institutes, and industry. Based upon data obtained from 130 user members of the National Nanotechnology Policy Centre, this study analyzed assessed asymmetries in web users' feelings based on hypothesized provision and non-provision of web portal requirements. In doing this, this study utilized measures and procedures suggested in the literature such as the most frequent-response categorization, customer satisfaction (dissatisfaction) coefficient, category strength and total strength, and Fong test. This study found that overall, sectors were an important factor in explaining the relationships between web portal requirements and user satisfaction/expectations. When these requirements were classified, users' perceptions of information contents requirements were consistent across the sectors, but the other functional requirements including communication and collaborations considerably varied.

This paper examines users' emotion from both 2D and 3D web interfaces and finds their differences. First, 77 words representing users' emotion were collected from the previous research papers. Second, a web survey system was developed using these collected words and prepared 3 web interface prototypes to collect users' emotions from different types of web interfaces. Finally, a web survey was conducted and its results were analyzed. The result of the survey showed that there were emotional words that were commonly experienced from either 2D or 3D web interfaces. However, it also showed that there were emotional differences between 2D and 3D web interface; 3D web interfaces provide users with specific emotional experiences because of their own characteristics - depth and dynamic movement. It is believed that the words collected from the survey could be the criteria to evaluate the quality of the 3D web interfaces and encourage the research on users' emotion from 3D interfaces.

The environment of web service has changed a great deal due to the progress of internet technology and positive participation of users. The established web service is static and passive, but the recent web service is becoming dynamic and active. Web 2.0 reflects current web service change well. The primary feature of web 2.0 is positive participation of users. Since the size of generated information is becoming larger, it is highly required to share the information fast and correctly. The technology to satisfy this need is web syndication and tagging in web 2.0. The web syndication makes feeds for another site or users to receive the content of web site. In addition, the tagging is the kernel of a information. Many internet users share rapidly the information through tag search. In this paper, we propose the efficient technique to improve the web 2.0 technology such as web syndication and tagging by using the data collection engine. Data collection engine has stored in a database, a user's Web site to use the information. and it has a user's Web site with access to updated data to collect. The experimental results show that our approach can improve the search speed up to 3.14 times better than the existing method and reduce the size of data up to 66% for building associated tags.

Recently e-commerce trade on the web has grown rapidly in scale and complexity, just as web site designs and web servers have become more complicated. In view of these complexities, it is obviously difficult to analyse web user's data since they web users employ so many different web paths. The existing association rule investigation algorithms identify all items with a high correlation. However even though users often only want to find items in which they have interest, it is still difficult to find the rules they want out of all of the many association rules found by existing algorithms. In this paper, we propose a system linking each node with the sequence association rule, linking all routes after finding a path corresponding to a user with the association rule-one of the data mining techniques which identify user patterns in web user paths. The suggested system helps us construct individualized or customer-subdivided sites using the sequence association rule in order to harmonize the paths of web users with user characters.

In this research a food information contents available as well as for PC web and for mobile web users was designed. The web site providing service for PC web and mobile web clients focuses on offering data on individually matching food based on the member's information. The information obtained from the contents can be practically applied by mobile users helping them to take care of their health. This system focuses on wireless internet mobile users and offers various food menus with cooking videos and also information regarding food supplies for individually matching bibimpab recipes. It gives a good information about one of the most traditional Korean food bibimpab which is made of various kinds of vegetables and greens. It also contains nutrition balance information. Designing the web site as a web site available for wired wireless internet accesses makes it available at any place for mobile wireless internet users so that they can obtain all information regarding products and menu which are good for their health.

Mobile network has become an essential tool for mutual communications, so a survey research published that most of the smartphone users use Mobile Instant Messenger every day. In this paper, we developed a wire-wireless integrated web messenger that can be used in various platform of mobile devices and desktop computer for communicating between users of some companies. We defined a multi-organization as several independent companies. Our web messenger was developed for communicating of users of a multi-organization. So one of functions of our web messenger is to restrict access to some particular departments in each company for the security of their company. Developed web messenger worked reliably from variety of web browsers on most of platforms such as android, iOs and desktop computers.

Social Networks which is composed of network with an individual in the center in a web support mutual-understanding of information by searching user profile and forming new link. Therefore, if we apply the Social Network which consists of web users who have similar immanent information to web search, we can improve efficiency of web search and satisfaction of web user about search results. In this paper, first, we make a Social Network using web users linked directly or indirectly. Next, we calculate Similarity among web users using their immanent information according to topics, and then reconstruct Social Network based on varying Similarity according to topics. Last, we compare Similarity with Search Pattern. As a result of this test, we can confirm a result that among users who have high relationship index, that is, who have strong link strength according to personal attributes have similar search pattern. If such fact is applied to search algorithm, it can be possible to improve search efficiency and reliability in personalized and social search.

In this paper, we propose a customer personalized system that presents the web pages to users which are customized to their individuality. It analyzes the action of users who visit the shopping mall, and preferentially supplies the necessary information to them. When they actually buy some items, it forecasts the user's access pattern to web site and their following purchasable items and improves their web page on the bases of their individuality. It reasons the relation among the web documents and among the items by using the log data of web server and the purchase information of DB. For reasoning, it employs Apriori algorithm, which is a method that searches the association rule. It reasons the web pages by considering the user's access pattern and time by using the web log and reasons the user's purchase pattern by using the purchase information of DB. On the basis of the relation among them, it appends the related web pages to link of user's web pages and displays the inferred goods on user's web pages.
