This study measures the effectiveness of 39 Korean Government websites in providing equitable and appropriate government information to the public. 39 government web sites were divided into two groups, 21 "departments or ministries" and 18 "offices". Five evaluation criteria were information contents of services, fluent operation of services, feedback mechanism, easiness of access, and design. The study showed that there are some different results between 21 "departments or ministries" and 18 "offices". Most information services provided by Government websites were slightly moderately appreciated by the researchers. Some problems and resolutions for the improvement of government websites are provided. Also, some suggestions for the government website designers and administrators are made.

With the spread of the Internet, users can easily receive various services and exchange information through the web. There are several requirements for building a web system, and it must be developed using a programming language or platform for user purposes. Residual material information refers to information on medicines and pesticides added to food, and residual material standards are used to measure the level of residues in food produced by companies and farmers to determine whether those levels meet domestic or international standards. Currently, the Ministry of Food and Drug Safety provides residual acceptance standards for food additives, including food, pesticides and animal medicines, in the form of documents, which must be serviced smoothly and conveniently by users through the establishment of a web system. It must also meet a variety of requirements, including user accessibility, such as scalability and compatibility. This paper proposes react-based residual material information web system that allows users to access more conveniently and receive residual material information smoothly. We measured the speed for the three inportant functions of information provision and compared them with existing residual material information web systems and qualitatively evaluated the seven essential requirements: scalability, compatibility, and accessibility.

Web Game provides computer games through a web browser, and have several benefits. First, we can access the game through web browser easily if we are connected to the internet environment. Second, usually we don't need much space of a game data for downloading it into a local disk. Nowadays, an industry area of Web Game has a chance to grow through advancements of mobile computing technologies and an age of Web 2.0. This study proposes a Web Game system that users can apply to manipulate the game with multimodal interfaces and mobile devices for intuitive interactions. In this study, multi modal interfaces are used to efficient control the game, and both ordinary computers and mobile devices are applied to the game scenarios. The proposed system is evaluated in both performance and user acceptability in comparison with previous approaches. The proposed system reduces total clear time and numbers of errors of the experiment in a mobile device. It can also provide good satisfactions of users.

Nowadays, IT for CRM has been growing and developed rapidly. Typical techniques are statistical analysis tools, on-line multidimensional analytical processing (OLAP) tools, and data mining algorithms (such neural networks, decision trees, and association rules). Among customer data, web log data is very important and to use these data efficiently, applying OLAP technology to analyze multi-dimensionally. To make OLAP cube, we have to precalculate multidimensional summary results in order to get fast response. But as the number of dimensions and sparse cells increases, data explosion occurs seriously and the performance of OLAP decreases. In this paper, we presented why the web log data sparsity occurs and then what kinds of sparsity patterns generate in the two and t.he three dimensions for OLAP. Based on this research, we set up the multidimensional data models and query models for benchmark with each sparsity patterns. Finally, we evaluated the performance of three OLAP systems (MS SQL 2000 Analysis Service, Oracle Express and C-MOLAP).

Diverse disciplines such as information science, computer science, cognitive science, and industrial design, are activity engaged in the website evaluation research efforts. Information scientists emphasize the importance of user-centered and user-friendly website design, which is also easy to use, This idea is based on the understanding that the users and the designers are different set of people. In addition, information scientists consider the practice of maximally incorporating user inputs during the website design to be very important guideline. However, this study is based on a newly emerging population of website users who are also designers. 218 study participants evaluated the websites that they designed in comparison to the websites designed by others. According to the survey data analysis, the study participants considered the content delivery, design simplicity, design consistency, and link access of the websites to be equally important from both users' and designers' perspectives. However, the content organization, rich content, and screen composition were underestimated from the designers' point of view whereas these factors were considered to be important from users' point of view.

This study discussed on production, procedures of collection, accessibility, copyright of archival records for designing oral history archive information system, and aimed to suggest practical standards by developing guidelines for evaluation and building of web oral history archives. For this, based on evaluation framework, guidelines for evaluation designed by researchers were applied to five domestic and foreign web oral history archives as case study analysis. Base on the results of the analysis, some possible suggestions were made for building successful web oral history archive information system in Korea.

월드 와이드 웹의 보편화로 인하여 급속하게 증가하고 변화하는 웹 문서는 검색엔진으로 하여금 색인된 웹 문서와 현재의 웹 문서의 일관성을 유지할 수 없을 정도이다. 이러한 문제를 해결하기 위한 방법으로 연구되고 있는 것이 특정한 주제를 정하고 정해진 주제에 관련된 문서를 수집할 수 있는 focused crawler가 제시되고 있다. 지금까지 다양한 접근방법의 focused crawler가 개발되었지만, 모두 웹 링크를 이용하여 연결되어 있는 문서를 평가하는 처리과정을 거치고 있다. 그러나 이러한 과정은 다양한 내용을 포함하고 있는 문서일 경우 관련내용이 존재함에도 문서가 버려지거나 사용되더라도 문서상의 모든 링크를 사용하여 처리하는 비효율적인 문제점이 발생한다. 이 논문에서는 웰 문서 내부에 포함되어 있는 정보를 온톨로지를 이용하여 평가함으로써 다양한 내용을 가진 문서에서 사용자가 원하는 정보를 찾을 수 있을 뿐만 아니라 정보와 관련된 링크만을 사용하여 보다 효율적이고 정확한 문서를 수집하고자 한다.

본 논문은 스프링 프레임워크를 이용한 클라우드 환경에서의 부실예측 지원시스템을 제안한다. 제안된 시스템은 자동화된 통합인증 및 접근제어 시스템으로서 각기 독립된 모듈에서 처리된 데이터를 기초로 거래관리 모듈로 통합하여 부실예측을 평가하고 지원시스템의 데이터의 기법을 다른 모듈과 공유함으로써 자산의 부실채권을 이용한 회수를 관리하여 효율성을 높인다. 제안하는 시스템은 고객과 기업의 전략경영 등의 기능을 강화하여 업무투명성, 비용절감, 고객 접근성이 기존시스템보다 효율적으로 사용될 것으로 기대된다. 또한 프레임워크를 적용함에 따라 소프트웨어의 재사용성을 최대화할 수 있으며, 개발된 표준 API를 적용함으로써 개발비용 및 기간의 단축시킬 수 있으며, 각 컨테이너(공통모듈 플러그인) 형태로 프레임워크를 설계함으로써 기능의 추가가 쉽고, 재사용이 가능하며, 사용자가 요구하는 웹 환경을 구축함으로써 정부에서 제시하는 표준 프레임워크와 호환성을 제공한다.

In spite of various efforts to resolve digital divide of people with disabilities, it still has a long way to go because there lack of identifying information needs of people with disabilities and potential users including their family and the related, and integrated information channels such as a portal, and so on. In this context, this study aims at analyzing the users' unique information behavior and evaluating usability of domestic web information services for people with disabilities which are currently serviced. Increasingly, we suggest new functional requirements of building a library portal for people with disabilities.

The structuring of Web information supports a strong user side viewpoint that a user wants his/her own needs on snooping a specific Web site. Not only the depth first algorithm or the breadth-first algorithm, but also the Web information is abstracted to a hierarchical structure. A prototype system is suggested in order to visualize and to represent a semantic significance. As a motivating example, the Web test site is suggested and analyzed with respect to several keywords. As a future research, the Web site model should be extended to the whole WWW and an accurate assessment function needs to be devised by which several suggested models should be evaluated.
