Nowadays, highly advanced medical imaging devices, like MRI(Magnetic Resonance Imaging), are developped and have become rather common apparatus for medical research of the human brain. No matter how much data is obtained, however, it is nothing without appropriate measure for searching and analyzing it. The necessity of sophisticated database management systems for three-dimensional brain images is now clear. ¡¡¡¡A three-dimensional brain image database which consists of about 1000 brain images taken from normal subjects are under construction. In this paper, what have accomplished on the database up to now will be introduced and several issues on general design of such kind of database are discussed.

A new approach to get a qualified view on large amounts of materials data is proposed. Global understanding on the relations among chemical composition, crystal structure and properties of materials on the basis of suitable classification is a starting point of material design. The present work is focused on studying the crystal structures and structural primitives as keys for materials design based on crystallographic information, and a sequence of stacking 2-dimensional layers, implying hidden regularities in the high temperature superconducting (HTSC) materials, is selected as an additional features to generic crystallographic information. ¡¡¡¡Prerequisites for using this approach, its limitations and possibilities for database developments are discussed based on the analyses of data extracted from Inorganic Crystal Structure Database (ICSD) . In addition, possible applications of this method for classification and design of these interesting materials are proposed.
