Nowadays, both large and small business organizations have been using the Internet in general or the World Wide Web in particular to cope with the global competition. One of the major purposes that these business organizations utilizations utilize the World Wide Web is to support their marketing activities. In this study, we compared the uses of the World Wide Web, for supporting seven different categories of marketing activities, among three different groups of companies: the Top US corporation, the Top Non-US corporation, and the Top Web site groups. Results of the study showed that companies in the ToP US corporation and the ToP Non-US corporation groups primarily focused on Public Relation, while companies in the Top Web site group emphasized Encouragement. The Top US corporations also focused on the Interactive Brochure and the Top Web site companies were significantly different from the Top Non-US corporations with regard to Direct Sales and Customization. We discussed the potential reasons for these similarities and differences. The study also provided the extension for future research and discussed its limitations.

In this study, discourse patterns of four peer small groups in learning science concepts were examined. Verbal interactions during small group discussions were audio- and video-taped, transcribed, and analyzed. Three coding frameworks for the levels of turns, interaction units, and episodes were developed. In the analyses of turns, no clear relationships between students' prior achievements and contributions to knowledge building processes were found. Partly participating modes and symmetrical interaction modes were dominant in the analyses of interaction units to suggest that some students did not participate actively in small group discussions and that students' verbal interactions were superficial. The analyses of episodes also indicated that agreeing and/or partial elaborating on group members' ideas were the most frequent patterns and dialectical exchanges were rare in small group discussion.

High quality real-time interactive multimedia services like VOD gained huge momentum by information technology industries during the middle of 1990, but failed successful commercial service deployment despite of the expectations. Among the number of reasons, lack of high bandwidth and QoS support from the network infrastructure have become main cause of the failure. On the other hand, the advance of computer industry-driven storage technologies has been reducing the price of in-home storage dramatically. This fact and the delivery of audio-visual material in a digital form to the home storage make very interesting multimedia service applications possible. It enables anytime content delivery (e.g., during off-peak time) without user interaction and anytime content play and, also, enhances utilization by reducing the loads applied to servers and networks using multicast network infrastructure. In this paper, we propose design and implementation of our anytime multimedia service system based on in-home storage, called IMPRESS-AMS.

This paper describes how to distribute high multi-dimensional facial expression data of vast quantity over a suitable space and produce facial expression animations by selecting expressions while animator navigates this space in real-time. We have constructed facial spaces by using about 2400 facial expression frames on this paper. These facial spaces are created by calculating of the shortest distance between two random expressions. The distance between two points In the space of expression, which is manifold space, is described approximately as following; When the linear distance of them is shorter than a decided value, if the two expressions are adjacent after defining the expression state vector of facial status using distance matrix expressing distance between two markers, this will be considered as the shortest distance (manifold distance) of the two expressions. Once the distance of those adjacent expressions was decided, We have taken a Floyd algorithm connecting these adjacent distances to yield the shortest distance of the two expressions. We have used CCA(Curvilinear Component Analysis) technique to visualize multi-dimensional spaces, the form of expressing space, into two dimensions. While the animators navigate this two dimensional spaces, they produce a facial animation by using user interface in real-time.

The purpose of this study is to identify the characteristics of reading education of the specialized high schools for an alternative education. Among the specialized high schools for an alternative education, five schools were selected for the study. To achieve the study purpose, interviews were conducted with the teachers in charge of reading education of the schools. The interviews were recorded and transcribed. According to the study results, there have been attempts to integrate curriculum and reading education based on humanities. Students were actively participating in planning and conducting reading programs. Furthermore, there were Library Assisted Instructions. In order to proceed successfully with the reading education, there were several important factors as follows: 1)there was an organized system to support reading education by teachers, schools, and school libraries. 2)students' interests and needs were reflected in designing reading programs, 3)reading programs were adjusted according to students' needs and interests, and 4)reading activities were emphasized.

We present a scheme and a data structure that decompose the space into adaptive-sized cells to improve the visualization of soft objects. Soft objects are visualized through the evaluation of the field functions at every point of the space. According to the propsed scheme, the affecting soft objects for a point in the space is searched through the data structure called interval tree based on the bounding volume of the components, which represent a soft object whose defining primitive(skeleton) is a simple geometric object such as point or line segment. The bounding volume of each component is generated with respect to the radius of a local field function of the component, threshold value, and the relations between the components and other neighboring components. The proposed scheme can be used in many applications for soft objects such as modeling and rendering, especially in interactive modeling process.

We present a new interactive technique for directing the motion sequences of an animated character by dragging its specific body part to a desired location in the three-dimensional virtual environment via a hand motion tracking device. The motion sequences of our character is synthesized by reordering subsequences of captured motion data based on a well-known graph representation. For each new input location, our system samples the space of possible future states by unrolling the graph into a spatial search tree, and retrieves one of the states at which the dragged body part of the character gets closer to the input location. We minimize the difference between each pair of successively retrieved states, so that the user is able to anticipate which states will be found by varying the input location, and resultantly, to quickly reach the desired states. The usefulness of our method is demonstrated through experiments with breakdance, boxing, and basketball motion data.

Humanities and social sciences researchers and database experts have teamed up to build a database of IPR materials prepared by the Institute of Pacific Relations (IPR). This paper presents the issues and solutions inherent in the database construction for ensuring the quality of IPR materials. For the accessibility of the database, we maintain the database on the Web so that researchers can access it via web browsers; for the convenience of the database construction, we provide an integrated interface that allows researchers to perform all tasks in it; for the completeness of IPR materials constructed, we support the responsible input and the responsible approval that identify responsibilities of each IPR material entered; and for the immediacy of the approval, we support an interactive approval process facilitating the input of researchers. We also use database design, query processing, transaction management, and search and sorting techniques to ensure the correctness of IPR materials entered. In particular, through concurrency control using existence dependency relationships between records, we ensure the correctness between the operating system files and their paths. Our future studies include content search, database download and upload, and copyright related work on IPR materials.

The study is about the national defense 2020 plan. According to the reduction of military bases, It should be needed to be integrated as a high-tech camp. So we researched and did a fact-finding survey mainly in Gyeonggi Province. After the research, first, It should be reset the regional development planning and the retention criteria of harmonized camp. Second, the neglected and scrapped camps should be put into order to activate the local economy by handling procedure. Third, it should have dedicated consultative bodies, exclusive departments and professional staff to communicate with the military authorities and the citizens. Fourth, if there are any causes of civil appeals such as shooting ranges should be in the underground. Lastly, To get support smoothly, it should be reflected by enacted special laws and ordinance regulations. This material could be used when the Ministry of National Defense has a discussion with Gyeonggi Province.
