In highly informative, perception-rich environments that we call Omniscient Spaces, robots interact with physical objects which in turn afford robots the information showing how the objects should be manipulated. Object manipulation is commonly believed one of the most basic tasks in robot applications. However, no approaches including visual servoing seem satisfactory in unstructured environments such as our everyday life. Thus, in Omniscient Spaces, the features of the environments embed themselves in every entity, allowing robots to easily identify and manipulate unknown objects. To achieve this end, we propose a new paradigm of the interaction through Radio Frequency Identification (RFID). The aim of this paper is to learn about RFID and investigate how it works in object manipulation. Specifically, as an innovative trial for autonomous, real-time manipulation, a likely mobile robot equipped with an RFID system is developed. Details on the experiments are described together with some preliminary results.

The modern contains many problems that cannot be solved by the reductionism based on western natual science. Up until now, it has been formed determinism over the basis of empiricism or rationalism, this can be called a mechanical view of the world. In the field of natural science since 20C, however, raised the standard of revolt in traditional determinism, plural theory headed up. Consequently, in the name of post modernity, western reason became to deconstruct, further, new theory came to need. This new paradigm also affected design, and was studied to overcome the limitation of modern design.

GIS can supply large quantitiy of useful information about spacial relationship, consequently there exists great potential of GIS support ing for decision making strategies related to urban design and environmental planning. In different discipline areas there exist different information representation methods and considerations having direct or indirect relationship with spacial information, how to use GIS as a tool for facilitating the work in other discipline field, there are two basic questions crucial to the success of these interdiscipline applications. The first one is interoperatability among GIS and other applications, the second is the paradigm difference between GIS and other domain field regarding problem solving. In this paper, we investigate the spatial information of the urban environment provided in the analyses of the urban visual sustain ability, urban daylighting environment and urban wind environment. We also discuss the challenges and opportunities for cross-disciplinary GIS application regarding the aspect of Information Collection, Information Generation, Information Analysis and Information Visualization.

Recently, we have witnessed a host of emerging tools in the management support systems (MSS) area including the data warehouse/multidimensinal databases (MDDB), data mining, on-line analytical processing (OLAP), intelligent agents, World Wide Web(WWW) technologies, the Internet, and corporate intranets. These tools are reshaping MSS developments in organizations. This article reviews a set of emerging data management technologies in the knowledge discovery in databases(KDD) process and analyzes their implications for decision support. Furthermore, today's MSS are equipped with a plethora of AI techniques (artifical neural networks, and genetic algorithms, etc) fuzzy sets, modeling by example , geographical information system(GIS), logic modeling, and visual interactive modeling (VIM) , All these developments suggest that we are shifting the corporate decision making paradigm form information-driven decision making in the1980s to knowledge-driven decision making in the 1990s.

시소러스는 구축 방법에 따라 매뉴얼 시소러스와 통계적 시소러스로 구분된다. 매뉴얼 시소러스는 정확한 의미 표현이 가능하지만 구축과정에 많은 비용이 소요되며, 통계적 시소러스는 자동으로 구축될 수는 있지만 개념간 의미 표현력이 부족하여 만족할 만한 검색 성능 향상을 기대할 수 없다. 따라서, 본 논문에서는 메뉴얼 시소러스에 객체 지향 개념을 적용하여 구축 비용을 감소시킬 수 있는 시소러스 구축기와 데이터 추상화 기법을 이용하여 선별적으로 개념들 간의 관계를 쉽게 참조할 수 있는 시소러스 시각화 브라우져를 구현하였다. 이 시스템은 시소러스 구축 과정에서 한 사람 이상의 전문가에게 일관된 관점을 제공하며 사용자에게는 높은 정확률의 검색 질의를 구성할 수 있도록 지원한다.

Humans use images on a daily basis-so much so that images are integral to their lives. Seeing is represented by an image, created or lived in it. Images required and developed a new paradigm from past to present. Today, images are in digital formats, and new techniques are increasing. Among them, cinemagraphs can find features that differ from previous images. The keywords found by comparing them in the image development are analyzed in detail through four characteristics in this paper. Cinemagraphs appearing in the keywords are interpreted in terms of each keyword and, through the example, the cinemagraph image can be approached concretely.

The conventional computing is a centralizing system, but it has been gradually going to develop ubiquitous computing which moves roles away from the main. The Community Computing, a new paradigm, is proposed to implement environment of ubiquitous computing. In this environment, it is important to accept the user demand. Hence in this paper recognizes pattern of user's activity statistically and proposes a method of pattern estimation in community computing. In addition, user's activity varies with time and the activity has the priority We reflect these. Also, we improve accuracy of the method through Knowledge Base organization and the feedback system. We make program using Microsoft Visual C++ for evaluating performance of proposed method, then simulate it. We can confirm it from the experiment result that using proposal method is better in environment of community computing.

The Internet technology has been recognized not only as a tool far communication in the 21st century but also as an environment for enabling changes in the paradigm of teaching and learning. This paper describes a web-based system development for chemical engineering education. Simulation and visualization of dynamic systems in the environment of a standard web-browser is made possible by extending its capabilities. ActiveX control is used to simulate the system tool far online representation of Virtual Lab. System that is developed using visual basic. The courseware is classified into tutorial, exercises, and virtual experiments.
