Nowadays the realm of intermediate energy as a bridge

between nuclear and particle physics attracts considerable

interest. This volume surveys recent developments in the

theory of quark correlations in hadronic matter and also

informs about experimental findings. The main themes are:



dynamicalsymmetries of heavy quarks, diquarks, weak

interactions, hadron spectroscopyand quark models, chiral

invariant quark forces, quark confinement and quarkaspects

of hadronic interactions.
