As quantity of information has been increased rapidly, the importance of efficient information analysis system has increased. This research suggests the direction of GNSS (Global Navigation Satellite System) technology strategies with information analysis on SCI Expanded DB. Exactly, it analyzes paper map and network structure between nations, between institutes and between authors. As a conclusion, it suggests strategies to take an opportunity for emerging technology and secure a leading position.

What kind of information is it got in an exhibition space? And any order is determined and can read an exhibition? Is application possible with interactive design in an exhibition space? All elements must be reflected in an information design in addition to a biological process and perception process. Various uncertainty, a little information about exhibition contents and negative attitude, various ways of thinking, time physical a few psychological fatigue, uncertain target will be for these reasons. When configuration of a space and a human biological element are satisfied in an information design by physical configuration, maximization of a communication between exhibition water and visitor firm names will consist in a museum.

Many studies have regarded an information infrastructure as one of the crucial factors for national or regional innovation in the information society, but few studies have empirically tested the role and the effects of it. Also, the information society have been studied to what extent, but information space structure and the reorganization for the resource of the material and the labour have not been considered. Therefore, this study is examining the relation between the linkage structure and the information change in the manufacturing sector. And for the empirical analyses, regional labour data for 16 Metropolitan Areas(Si) and Provinces(Do) in 1991-1996 are used. An analytical model and hypotheses are proposed for empirical testing. The main finding is that if inter-regional wages condition is identical, inter-regional labour flow has positive correlations with regional information level.

GIS is a integrated information system that is designed for collect, store, renovate, space analysis, representation effectiveley of information which was formed by space information of features such as mountain, pavement, building , river, communiction, power, gas line, natural resource. the core technology of CIS are the open GIS component technology, spae information circulation, advanced GIS application technology and space data forming technology. In this study, GIS core technology development, market and standization are represented.

In this paper, we propose a 3D view design scheme which arranges 2D information in a 3D virtual space with a flexible interface and voice information. The scheme allows the user interface of the 2D image in 3D virtual space anytime from any view point. Voice information can be easily attached. It is this simple and efficient image and voice information arrangement in 3D virtual space that improves information transfer.

As an application of dimensional analysis in the theory of chaos and fractals, we studied and estimated the information dimension for various phonemes. By constructing phase-space vectors from the time-series speech signals, we calculated the natural measure and the Shannon's information from the trajectories. The information dimension was finally obtained as the slope of the plot of the information versus space division order. The information dimension showed that it is so sensitive to the waveform and time delay. By averaging over frames for various phonemes, we found the information dimension ranges from 1.2 to 1.4.

While most GIS are based on Euclidean space, cellular space can be used as an alternative type of space for a large number of GIS applications. In order to analyze the pattern of moving objects in cellular space, we need new definitions of similarity between their trajectories since the trajectory in cellular space significantly differs from those in Euclidean space. In this paper, we study the properties of moving objects in cellular space. Based on these observations, we propose several similarity measures between trajectories in cellular space. We analyze the difference of the proposed measures by experiments.

We propose an global color model based method for tracking motions of multiple human using a networked multiple-camera system in intelligent space as a human-robot coexistent system. An intelligent space is a space where many intelligent devices, such as computers and sensors(color CCD cameras for example), are distributed. Human beings can be a part of intelligent space as well. One of the main goals of intelligent space is to assist humans and to do different services for them. In order to be capable of doing that, intelligent space must be able to do different human related tasks. One of them is to identify and track multiple objects seamlessly. In the environment where many camera modules are distributed on network, it is important to identify object in order to track it, because different cameras may be needed as object moves throughout the space and intelligent space should determine the appropriate one. This paper describes appearance based unknown object tracking with the distributed vision system in intelligent space. First, we discuss how object color information is obtained and how the color appearance based model is constructed from this data. Then, we discuss the global color model based on the local color information. The process of learning within global model and the experimental results are also presented.

Globalization, conversions, and OSMU (One Source Multi Use) in modern cultural industry is expanding fast, and global competition is soaring with a changing environment today. In fact, the development of one nation depends on its cultural creativity. Yet, there is an increasing need for a connection between space and culture since globalization homogenizes a nation's unique cultural identity and provides low level of utilization in digital cultural contents in terms of saving, conserving and maintaining data. In order to invigorate the cultural industry, there must be some information that provides public culture contents, which they can be freely searched, displayed, and re-produced. Ultimately, these public culture contents should be able to provide Culture Space. This text discusses how individuals produce the Culture Space, which provides digital information of time and space, from a relationship between culture and space. It also introduces the public Culture Contents service framework in order to provide culture information and combined Culture Contents.
