In this paper, we examine work in the evolution of content-based retrieval systems that rely on an intelligent infrastructure. Here, we refer to intelligence as the capabilities of the systems to build and maintain situational or world models, utilize dynamic knowledge representations, exploit context and overage advanced reasoning and learning capabilities. We argue that these elements are essential to producing effective systems for retrieving visual information at semantic levels matching those of human perception and cognition. In this paper, we review relevant research on the understanding of human intelligence and construction of intelligent systems in the fields of cognitive psychology, artificial intelligence, semiotics. We also discuss how some of the principal ideas from these fields lead to new opportunities and capabilities for content-based retrieval systems. Finally, we discribe some of our efforts in these directions. In particular, we present MediaNet, a multimedia knowledge presentation framework that facilitate and enable intelligent content-based retrieval.

Building a new library and remodeling an existing library for the multi-cultural space is a recent trend of the university libraries. That is, the spaces for using the digital and multimedia equipments, the rooms for reading and studying, the spaces for the cultural activities such as watching movies and holding an exhibition, and the spaces for the communication and refreshment are increasing in the libraries. However, this movement of securing and providing the new spaces is not closely connected with the off-line services and happens without the consideration of how to change the librarian's role and position. Therefore, the university libraries need to plan and provide the multi-learning space rather than the multi-cultural space considering the university library is an academic organization. Additionally, understanding the purpose of the university libraries, user's need, utilization method of books and considering the librarian's roles and placement are necessary in planning and providing the space of the libraries.

As the computer is popularized in individual and society, it is using in a many of area. In particular, there are many materials to learn a science knowledge using multimedia through computer. Many of them are web-based learning materials, which are developed by Java or Flash. Since the technology of the representation, storage, com-putation and communication in computer make progress, the environment of education is also developed. Especially, the internet and VR technology will cause the education to change. A key feature of VR is real-time interactivity, in that the computer is able to detect student input and instantaneously modify the virtual world. It is reported that using the VR simulation in chemistry education can increase student engagement in class, promote understanding of basic chem-ical principles, and augment laboratory experience. In this study, application way of the virtual reality technology in chemistry education is examined.
