This paper introduces an hypermedia program supportable for teaching secondary and upper secondary level geometry. This program links users to files written in other softwares and internet web sites to provide information and exploratory environments with softwares. The linkage with the interactive dynamic software(GSP) files to teach hyperbolic geometry is illustrated with sample screens.

All-IP 망에서는 core 망 뿐만 아니라 무선망 모두 IP 공유패킷망 (shared packet network)으로 구성된다. 특히 유선망에 비해 대역폭이 제한적인 무선패킷망에서 사용자의 QoS 요구를 만족시키면서 성능을 최대화시키는 것은 매우 중요하다. 본 논문에서는 Web-browsing 과 같은 대화형 (interactive) 데이터 사용자를 위한 무선공유패킷망을 모델링하고 사용자 관점의 성능 분석 결과와 시뮬레이션 결과를 보인다.

Web-based Promotion of companies have several advantages: They can publicize the brand image in various ways; they enable consumers to learn the information of products in the round with interests; they can stretch out their marketing targets to the whole world. In order to make an effective delivery of their information in such promotion websites, interaction with their consumers is an important factor, for which understanding Interactive Storytelling is essential. The purpose of this thesis is to study Interactive Storytelling which enables us to have effective interaction with consumers in making promotion websites of companies. For this, this thesis analyzes examples of Interact Storytelling focused on it have story promotion websites on the basis of the five steps for internet marketing promotions: attraction of visitors, attraction of interests and participations, acquisition of the information of customers, grasp of the needs of customers, and an offer of values classified by customers.

Extensible 3D (X3D) is the ISO standard for defining 3D interactive web- and broadcast-based 3D content integrated with multimedia. With the advent of this integration of interactive 3D graphics into the web, users can easily produce 3D scenes within web contents. Even though there are diverse texture nodes in X3D, projective textures are not provided. We enable X3D to provide SingularProjectiveTexture and MultiProjectiveTexture nodes by materializing independent nodes of projector nodes for a singular projector and multi-projector. Our approach takes the creation of an independent projective texture node instead of Kamburelis's method, which requires inconvenient and duplicated specifications of two nodes, ImageTexture and Texture Coordinate.

As the cost of installing and maintaining software on large organizations such as recent companies and schools has increased, software installation and maintenance costs are low, system management is easy, demand for ease of use software solutions has increased. In the reality that special education for service center engineers is required along with the release of various products, training of the software and solution industry is regarded as important. Building Web-based user and system interactive environment, strengthened usability and educational ability effect suitable for engineer level. In the future, research that is familiar with specific software, not successfully combining multiple frameworks, rather than developers, will be increasingly important for research that can achieve optimal performance.

Since the origin of the web site in ti)e first part of the 90's there has been discussion regarding the function of aesthetics. Visual aesthetics has for the most part played an absolutely necessary role in human-computer interactive research. This study is intended to design websites on aesthetic aspects which focuses on the websites of universities in Korea and China. What exactly are the differences and commonalities of each; and how they have been clarified by methods of empirical research on aesthetic measurements.

An electronic statistics text on the web is implemented. The introduced text provide interactive instructions on the statistical estimation and inference. As a by-product, we also provide a calculation of quantiles and p-value of t-distribution and standard normal distribution. This program was written in JAVA programming language.

In this paper, we compared the user experience according to utilize parallax scrolling technique in web site. For this purpose, we divided subjects into two groups. The subjects of Group1 were given to use web site interface with Parallax scrolling and the Group2 were given to use web site interface with non Parallax scrolling. Then, All Subjects answered the questionnaire of user experience. User experience were evaluated by four entries as Novelty, Esthetics, Usage of Satisfaction, Cheerfulness. Consequently. As a result, the web site interface with Parallax scrolling showed significantly higher score of Novelty, Esthetics, Cheerfulness than the web site interface with non-Parallax scrolling. In this study. we proved that using the parallax scrolling technique in web site interface improves the overall user experience, and suggested to apply as a way to advance the attention and persistency on creating a web site.
