For this, technical method is proposed for blocking swearing words or sentences by analyzing swearing words usage types and behaviors. This system consists of 3 steps. Firstly, a survey, analysis of swearing words on web board and algorithm proposal for blocking these words must be studied. Secondly, sufficient and concrete opinion researches about every generations for measuring swearing degree must be accomplished. Finally, implementation on web board by programming will be done. This paper, in the first, deals with usage analysis of swearing and algorithm developement for solving these problems.

Recently as the Internet services become popular, the number of practical approaches to tackle social problems by using computers is increasing rapidly. One of the typical problems is the surveying system that handles a large amount of various data and thus requires much effort in time and manpower. As the necessity of the computerized surveying system is increased, there have been many tries to develop the surveying system based on the web or standalone software for public opinion collection, market research, and so on. In this paper, we design and implement a respondent based real-time surveying system using XML and QCL in order to efficiently process a various style of questionaries.

The purpose of this study was to explore whether the concept of amount of invested mental effort (AIME) developed in the field of educational psychology can help explain why people put so little effort into online searching. In this experimental study, two information retrieval systems - a web search engine and a university library system - were used to make a comparison. The data were collected from 15 undergraduate students through background questionnaires, think-aloud protocols, search logs, post-search questionnaires, and post-task interviews. The findings indicate that perception of the web's "easy-ness" and high levels of self confidence in searching capability led the subjects to put less effort into web searching than they do into library system searching. In addition, the perceived difficulty of search task influenced the extent of mental effort invested. The AIME proved a useful framework for understanding search behavior and user experience for both web search engines and library systems.

In this study, we wanted to find out about the perceptions and the requirements of the academic information service users about the Library 2.0. This study used the survey research method, which utilized the web-based survey using the academic information service users as the target population. Specifically, we studied whether and how the users recognized and experienced the Web 2.0 technologies and its related services with respect to Library 2.0. In addition, we gathered the requirements for the Library 2.0 concept applied information services. The analysis results showed that the users were in need of obtaining the most up-to-date information and also using the professional information services such as the experts generated information contents and the Google Scholar type document reference information services instead of the Library 2.0 services based on the Web 2.0 technologies.

Recently, as more web-based applications are widely used, various methods for education are developed in practical areas. As a result, in many organizations, virtual educations such as WBI learning. CAI, and distance learning are offered actively. With the advantages of web-based education, in order to achieve feasible and efficient effects on education. a new web-based instruction model that considers the abilities, the interests, and the aptitudes of students individually is required. In this paper, a new web-based instruction model, called a hybrid model, is proposed and implemented. And then, two model - the stepwise model and the hybrid model- are applied to a computer accounting class of a vocational high school. Students attend the web-based class in a computer center for 100 minutes autonomously. After the classes, a questionnaire is made in order to analyze both the effect on that class and the learning fulfillment of the proposed instruction model.

With the increase of the number of Internet users, various methodologies have been proposed for the effective design of web page. However, the prior methodologies have focused only on the functional aspect of web page while ignoring the emotional aspects of web pages. This paper focuses on the emotional design of home pages and aims to provide a methodology to design a web page suitable for goal emotions. In order to achieve the main purpose, we have conducted three related studies. First, we have identified basic emotional dimensions representing various feeling users have from web pages as a pool of emotional adjectives. Second, we have identified key design elements related to the emotion by observing the design process of expert designers. Third, we examined the causal relation between the perceived emotion and designed elements. The results indicate that some design elements are more effective to produce certain feeling than others. This paper ends with limitations and implications of the study results.

The purposes of this study were to examine the features of web fashion magazines and to suggest an effective website model for them. Seven web fashion magazines were analyzed. The evaluating criteria included: contents, design, navigation, and services. In addition, online-questionnaires were sent to 40 end users to obtain the information regarding user behaviors on the elected web fashion magazines. The results show that a suggested model should include various aspects: 1) providing currents information. 2) consistency in design, 3) easy in navigation, and 4) searching function etc.

For improving social safety, It is important to build Web DB of criminal prevention and open to the public. It could be help to mitigate social damage of crimes and accidents. In this study, the main goal is to analyze and apply the applicable contents from user demands studies and case studies for a domestic life safety Web DB. For this study 31 cases of international life safety Web DB were collected and analyzed. Customer participation style of Web service was reviewed. And demand survey for crime weakness group like students, and young women was examined. As a results people needed to know the un-safety area in their usual life and their ways; school to home, work to home. While creating the Web DB for domestic life safety, user content according to different economic status and publicity for Web DB proved to be important factors.

The purpose of this study was to design an extensive evaluation model for the quality of web-based database and to make a comparative analysis of People's awareness of the importance of assessment indices. The evaluation standard developed in this study was constituted by 19 indices and 45 elements in three different areas, including data, service and effectiveness. And a survey was conducted on database experts and nonprofessional users to find out their awareness of the importance of web-based database evaluation elements, and the findings of the study might contribute to laying the foundation for expediting more in-depth research efforts in the future.
