Experts and technicians in the Changchun Institute of Applied Chemistry, CAS, has successfully developed the first rare earth nano-screen in China.

Since its first appearance in the 1990s, the rear-projector color TV has been widely praised for its large screen, good clarity and gay colors, thus becoming the new trend for the development of TV industry. However, many disadvantages of the rear-projector color TV still remain unsolved, including its small field view, low and uneven brightness. Experts and technicians in the Changchun Institute of Applied Chemistry realize that nano material have many features different from macro materials, and rare earth has special functions in the aspects of photo electromagnetism and chemical study. As a result of their arduous work, they overcame the difficulties in rare earth nano oxide conglutination and moisture absorption and successfully developed rare earth nano oxide with receiving rate higher than 90% and particle diameter less than 40 nm. A splendid result would be achieved if this rare earth nano oxide were painted on projector screen evenly. The angle of projector-screen's field view is increased. When looking at the screen from an angle of 180 degrees, one can find that the screen is still very clear with gay colors. The results are satisfactory from any direction and angle people observe it.

International Conference on Algorithm & Architecture for Parallel Processing held in Beijing

The 5th International Conference on Algorithm and Architecture for Parallel Processing was held in Beijing on October 23-25, 2002. It was co-organized by Deakin University and Computer Network Information Center, CAS. More than 80 experts and professors from USA, Japan, India, and regions of Taiwan, and Hong Kong attended the meeting. A discussion was focused on two broad areas: parallel and distributed computings, including architecture, algorithm and networks, and systems and applications. The discussion was ardently carried on "Exchange and share of computing and other information resources by wireless network". Participants believed that CLUSTER would be the main trend of the development of parallel computer in few years from now.-16

APCHI 2002 Held in Beijing

The 5th Asia-Pacific Conference on Computer-Human Interaction (APCHI 2002) was held in Beijing Friendship Hotel from November 1-4, 2002. The meeting was organized by CAS Institute of Software (ISCAS), and funded by the Technical Committee on Human-Computer Interaction (TC 13) of International Federation of Information Processing (IFIP), IEEE-CS China Section, etc.

The Human-Computer Interaction (CHI) emerges gradually as one of the 21st century's key technologies, and it is likely to be the focus of IT competition. In this connection, APCHI 2002 furnished an opportunity to boost the common CHI progress in Asia-Pacific Region, and attracted researchers of various academic backgrounds, such as ergonomics, CHI, information system, software engineering, artificial intelligence, design methodology, social sciences, management sciences, etc.
130 scientists from more than 20 countries attended the meeting. The conference invited celebrated speakers, including Dr. John Karat, a CHI scientist and Chair of IFIP TC13, Prof. Daniel Siewiorek, Director of Human Computer Interaction Institute, Carnegie Mellon University, Prof. Masaaki Kurosu and Mr. Aaron Marcus, world-famous experts in usability engineering.

During the conference, the participants were arranged to visit The Human Computer Interaction Technology and Intelligence Information Processing Lab of ISCAS; all showed great interests to the lab's research of pen-user interface (PUI) and spoke highly of their excellent job.-20
