Automatic machines or smart robots are interconnected with distributed knowledge bases by nation- or world wide digital networks. They are supporting human life in various places, at the same time saving energy and resources. Technology and economic development are effecting rapid changes depending on the fields, regions and culture to the way people interact with the systems, while sometimes keeping, otherwise forsaking their own traditions. Man machine systems have to create new interaction styles between human and machine intelligence, support cooperation among different organizations and enhance situation understanding for the long and short term, or remote and local activities regarding performance, safety, security and satisfaction. The seventh IFAC/IFIP/IFORS/IEA symposium on Analysis, Design and Evaluation of Man-Machine Systems was held in Kyoto on September 16-18, 1998. At the symposium, 99 papers were presented including four plenary papers among 131 submissions.

Celebrating Volume 100: Thirty years ago Springer-Verlag together with a distinguished Board of Editors started the series "Structure and Bonding." Initially the series was set up to publish reviews from different fields of modern inorganic chemistry, chemical physics and biochemistry, where the general subject of chemical bonding involves a metal and a small number of associated atoms. Three years ago the aims of the series was refined to span the entire periodic table and address structure and bonding issues wherever they may be relevant. Not only the traditional areas of chemical bonding will be dealt with but also nanostructres, molecular electronics, supramolecular structure, surfaces and clusters. With these aims in mind it is noteworthy that Volume 100 effectively reinforces and illustrates these ideals and is titled "Pi-Electron Magnetism" "from Molecules to Magnetic Materials."

Die Tachykiudien bei Aufregung, Scham, Zorn, aber auch Freude, sind ebenso Zeichen fUr die dominierende Rolle zentral-nervoser EinflUsse auf den Kreislauf wie die extremen Bradykardien im na- ttirlichen Schlaf. Das autonome Nervensystem vermittelt tiber seine vagalen und sympathischen Efferenzen diese Herzfrequenzreaktio- nen, und zwar unabhlingig von der Funktion homoostatischer Kreislaufreflexe, aber in enger Beziehung zum kortikalen Aktivie- fUr Anaes- rungszustand, der Vigilanz. Obwohl das Zielorgan thetika in erster linie das Gehirn ist und auch bekannt ist, d Anaesthetika die Vigilanz beeinflussen, wurde den zentral- nervosen Einfllissen bei der Beurteilung der Kreislaufumstellung in Narkose kal, lm Beachtung geschenkt. Vier Jahre lang hat Herr Priv.-Doz. Dr. K. Inoue die Bedeutung autonomer Antriebe auf das Herz fUr die Kreislaufumstellung in f t die Flille seiner Narkose tierexperimentell bearbeitet, und er Beobachtungen und die daraus folgenden Oberlegungen und Ver- allgemeinerungen in dem vorliegenden Buch, seiner Habilitations- schrift, zusammen. Es gelingt ihm durch Kombination verschiedener methodischer Ansiitze, u.a. durch Ableitung elektrischer Signale von vagalen Herz- efferenzen sowie durch wechselweise selektive Ausschaltung vagaler und sympathischer Antriebe auf das Herz am Beispiel einer Reihe von Injektionsanaesthetika verschiedenster Herkunft nachzuweisen, da1\ die fUr sie charakteristischen Herzfrequenzeffekte Folge ihrer zentral-vagolytischen Wirkung, nicht jedoch reflektorischer oder peripher-vagolytischer Natur sind.
