Conventional mobile telephony has moved from first generation analog devices, through to the second generation digital handsets we use today. We will shortly see the launch of third generation systems whose design has very deliberately been evolutionary rather than revolutionary. The 4th Generation telephony project takes a fresh approach to the provision of telephony services and seeks to develop sensible solutions to the problems of achieving voice communications between large populations of mobile users who are users of data as well as voice. This talk will give an overview of the directions that the 4th Generation Telephony project is taking. * * * * * * * * * * * * * * * 2nd Talk: Brain Mechanism with Consciousness ---Why are the livings living now?--- Prof. Katsuo HASEGAWA Graduate School of Mathematics, Nagoya University Abstract: Brain structure is deeply investigated and the so far accumulated experimental evidence with reference to consciousness under some clear mathematical definitions are also argued to elucidate the brain mechanism. Wide range of both established and interdisciplinary fields such as neurology, physiology, neuropathology, biology, physics, electrodynamics, probability theory, cognitive science, informatics and so on are mathematically unified to explain the brain mechanism itself and the reason why the present livings are living now being exempted from natural extinction. * * * * * * * * * * * * * * *
