In this paper, we propose the time relation model among the media with the concept of time and space on hypermedia system. This model classifies time proceeding relations in the node and among media connected with the link which is extended to internal link (while a current node remains, a destination node of internal link proceeds) and external link(a current node is replaced by a destination node of external link). Using this model, hypermedia system for hypermedia presentation is designed and implemented. This hypermedia system provides editing tools and controllers to created and edit nodes with time relation information, link tool to construct associative relations among nodes and navigation tool to control context flows.

Static CAD models are the CAD models that do not have feature information and modeling history. These static models are generated by translating CAD models in a specific CAD system into neutral formats such as STEP and IGES. When a CAD model is translated into a neutral format, its precious feature information such as feature parameters and modeling history is lost. Once the feature information is lost, the advantage of feature based modeling is not valid any longer, and modification for the model is purely dependent on geometric and topological manipulations. However, the capabilities of the existing methods to modify static CAD models are limited, Direct modification methods such as tweaking can only handle the modifications that do not involve topological changes. There was also an approach to modify static CAD model by using volume decomposition. However, this approach was also limited to modifications of protrusion features. To address this problem, we extend the volume decomposition approach to handle not only protrusion features but also depression features in a static CAD model. This method first generates the model that contains the volume of depression feature using the bounding box of a static CAD model. The difference between the model and the bounding box is selectively decomposed into so called the feature volume and the base volume. A modification of depression feature is achieved by manipulating the feature volume of the static CAD model.

The advent of powerful hardware and advances in high speed networks enabled synchronous learning, with teachers and students being geographically distributed but connected via computer networks. Today's synchronous learning systems are mainly based on video conferencing technology which provides audio, video, and joint editing of documents only, but does not take into account the specific requirements of teaching, for instance, controlling the course of instruction, raising hands, or reference pointing. A shared whiteboard is often the core part of these systems. Therefore, in this paper, we look into implementation issues in whiteboards of distance learning systems. Particularly, system architectures and concurrency control mechanisms are considered.

We are developing a minimized integrated public address system that has facilities such as external input, Mic., CD, MP3 and Radio. In this paper, developing an integrated public address system with operational MICOM will make it possible to control the facilities of digital devices centrally. The operational MICOM is composed of 3 layers which are a control layer, a processing layer and a user interface layer. The control layer controls digital devices in the integrated public address and the processing layer is for processing voice data editing, controlling signals of devices and providing status information of the device. The user interface layer displays the status of control devices and the data processing of a user. A remote control is used for the central control.

To provide high quality contents, game companies are introducing a new technology. One of the ways is the game character animation would utilize the motion capture. However, because of the economic burden, small businesses do not have a chance to take advantage of the motion capture. The purpose of this study is to derive benefit from cost and time saving by simplifying the existing production method based on a case of utilize to motion capture system. In addition this study has find ways to apply the key frame animation, so that is will be help to develop game contents.

It is possible to classify image data into two types according to the internal representation: one is bitmap, the other is vector. A bitmap image is represented by the two dimensional pixels whereas a vector image is represented by mathematical functions to draw vector objects such as line, rectangle and circle on the two or three dimensional space. So it is necessary for users to use a individual application program for each different image. In this paper, we present a method for design and implementation of image editing tool based on combining of bitmap and vector image.

Character agent based Multimodal Presentation Markup Language(MPML) has been developed to increase the efficiency of the presentation using a computer. However, authoring of a presentation by using MPML is not simple because MPML describes only the behavior of the character agent. It describes the presentation background by importing HTML documents. This paper proposes EMPML(Extended MPML) which describes not only the behavior of the character agent but also the presentation background. And an authoring tool for the EMPML has been designed and implemented. By integrating the editing of the presentation background and character agent behavior, the proposed authoring tool supports WYSIWIG(What You See Is What You Get) mode designing. By using the proposed authoring tool, users can make a multimodal presentation without knowing the details of EMPML.

Due to the increasing interest in SNPs and mutational hot spots for disease traits, it is becoming more important to define and understand the relationship between SNPs and their flanking sequences. To study the effects of flanking sequences on SNPs, statistical approaches are necessary to assess bias in SNP data. In this study we mainly applied Markov chains for SNP sequences, particularly those located in intronic regions, and for analysis of in-del data. All of the pertaining sequences showed a significant tendency to generate particular SNP types. Most sequences flanking SNPs had lower complexities than average sequences, and some of them were associated with microsatellites. Moreover, many Alu repeats were found in the flanking sequences. We observed an elevated frequency of single-base-pair repeat-like sequences, mirror repeats, and palindromes in the SNP flanking sequence data. Alu repeats are hypothesized to be associated with C-to-T transition mutations or A-to-I RNA editing. In particular, the in-del data revealed an association between particular changes such as palindromes or mirror repeats. Results indicate that the mechanism of induction of in-del transitions is probably very different from that which is responsible for other SNPs. From a statistical perspective, frequent DNA lesions in some regions probably have effects on the occurrence of SNPs.

This study aims to examine the way in which magazines represent housings, since magazines are one of major channel to connect individual houses with the public including professionals and the mass as well. Not only the professional architectural magazine but also women's magazine produce discourses which exercise huge influences on the public's understanding of the housings. After examining the different ways of representing housings in the houses related articles of architectural magazine and women's magazine, serious discrepancies have been noticed in both form and content of the text. In representing housings, women's magazine uses headlines and standfirsts with various modifiers to enhance the chance of interventions of the magazine/journalists. Focusing of the interests upon residents and architects, women's magazines force the reader to look at the housings through the frame of social status and celebrity of the residents and architects marginalizing actual houses. On the other hand, architectural magazines adopt externalized and objective way of representation using minimum layout elements following relatively uniform editing format. The abstract, rigid and masculine way of representation in the architectural magazines endow the published housings with the masculine and normative senses which can be seen as some sorts of aura which obstruct easy access to the housings themselves.
