  • SPDY is the new protocol proposed by Google to complement problems of HTTP(Hypertext Transfer Protocol)/1.1 and to improve web speed. In this paper, we evaluated the performance of SPDY protocol in a variety environment. By this evaluation, we examined the characteristics of the SPDY protocol and compared the differences between the existing protocol and SPDY protocol. And we took a closer look at the Flow Control of SPDY. Through this, we analyzed the problem of SPDY. It improved performance at 3G network environment, but failed to improve performance at high speed WLAN and mobility environments. We also verified that Flow Control does not work well. And finally we proposed directions for improvement of this protocol.

  • This paper proposes a methodology for effectively analyzing a lot of design information written from various design viewpoints in an integrated s/w development environment. It provides a way of extracting the inherent role of the design contents, as well as easily accessing and understanding the other related ones on the web. For this aim, it defines a series of methods 1) to correctly capture relationships between the contents and the other related ones, 2) to translate them into a web object equipped with hypertext links corresponding the relationships, and to navigate all the related contents with the links. The suggested methodology have three advantages. First, it supplies ways to analyze new design contents invented from different points of view. Second, it can help user to easily access the related contents using hypertext links over WWW. Third, it provides an environment capable of effectively sharing and accessing design contents distributed on remote sites, thanks to the platform-independent property of the web.

  • The network structures of a hyperlinked environment can be a rich source of information about the contents of the environment and it provides effective means for understanding it. Recently, there have been a number of algorithms proposed analyzing hypertext link structure so as to determine the best authorities for a given topic or query. In this paper, we review the algorithm of mutual reinforcement relationship for finding hubs and authorities from World Wide Web, and suggest SHA, a new approach for link-structure analysis, which uses the relationships among a set of relative authoritative pages, a set of hub pages, and a set of super hub pages.

  • The present Web surroundings is mostly composed of HTML(Hypertext Mark-up Language) and thereby users obtain web informations mainly in GUI(Graphical User Interface) environment by clicking mouse in order to keep up with hyperlinked informations. However it is very inconvenient to work in this environment comparing with easily accessed one in which human`s voice is utilized for obtaining informations. Using VoiceXML, resulted from XML, for supplying the information through telephone on the basis of the contemporary matured technology of voice recognition/synthesis to work out the inconvenience problem, this paper presents the research results about VoiceXML VUI(Voice User Interface) Browser designed and implemented for realizing its technology and also the VoiceXML Dialog designed for the purpose of the browser's efficient use.

  • This paper focuses on how the latest progress in digital media and technology affects the writing education environment. In the contemporary era, collecting numerous pices of information online, and arranging them to create new knowledge is important. There is also a need to seek new methods for writing education to stay in tune with the times. To that end, this paper suggests an open writing model using hypertexts. This writing model consists of a total of five stages, which are use of information, compilation of information, open mutual discussion, search of additional information and writing to recreate knowledge. The final outcome of such writing is writing using footnotes. By describing the gist of the keyword and adding numerous footnotes, such writing opens up an infinite possibility of re-creating information into new knowledge. This method can help university students who are accustomed to the digital society to proactively use information and improve multi-disciplinary communication skills required today. This author applied such a model to university writing education and found that more than 82% of the students were satisfied. Through the process of collaboration and recreation of knowledge in writing, learners found distinct benefits and noted their horizons had broadened. Given this effect, the open writing model using hypertexts is meaningful in that it forms a learning community that goes beyond a one-way feedback from instructor to student and instead nudges students to realize collective intellect. Moreover, it is meaningful in that it moves away from a top-down approach of the instructors passing down knowledge about writing and its rules, and towards a more proactive involvement by students in creating knowledge.

  • Increase of hypertext transfer protocol (HTTP)-based video popularity causes that broadband and Internet service providers' links transmit mainly multimedia content. Network planning, traffic engineering or congestion control requires understanding of the statistical properties of network traffic; therefore, it is desirable to investigate the characteristic of traffic traces generated, among others, by systems which employ adaptive bit-rate streaming. In our work, we investigate traffic originating from 120 client-server pairs, situated in an emulated laboratory environment, and multiplexed onto a single network link. We show that the structure of the traffic is distinct from the structure generated by first and second generation of HTTP video systems, and furthermore, not similar to the structure of general Internet traffic. The obtained traffic exhibits negative correlations, anti-persistence, and its distribution function is skewed to the right. Furthermore, we show that the traffic generated by clients employing the same or similar play-out strategies is positively correlated and synchronised (clustered), whereas traffic originated from different play-out strategies shows negative or no correlations.

  • Because of today's rapid growth of digital contents market and many benefits of electronic book, many people have considerable interest in E-book. Furthermore multifarious consortiums take an active part in standardization of I-book, and many E-book tools have been provided by software manufactures all over the world. E-book tools include editor for production of E-Book, viewer for reading, and the like. Especially in E-book viewer, annotation function has to be Included to put arrangement, summation, recording, comment, emphasis and after comprehension to practical use. In this paper, a E-book viewer with annotation is designed according to the specifications of EBKS, Korean standard. The proposed viewer is aimed to implement in PDA with embedded Linux, but developed in Windows 2000 platform. Because development environment and application environment are different each other, Qt-Library and cross-compiler are used for cross-platform development. The viewer support various functions such as adjusting of font size, hypertext linking, retrieval of specific word, and so forth. And in addition to these basic functions, annotation function is designed for the viewer, which can be used for re-usage and sharing of important information.

  • This paper studied the process of changes of the heading which is access point of the catalog in the cataloging Rules. The first described change of the concept of heading, and described change of headings in the Korean Cataloging Rules and Anglo-American Cataloging Rules And then described heading; in the online environment and future of cataloging rules. The concept of the main entry has lost any meaningful purpose in today's online catalog environment despite a multiplicity of definition. To bring cataloging rules up-to-date, Headings of KCR, AhCR2 Chapter 21, the MARC format and KORMARC format need to be revised The revision of this cataloging rules should be based on Hypertext and Hypermedia. A Continued empirical research would be most welcome, and should be incorporated into future cataloging rules.
