  This report attempts to summarize the most interesting (and hopefully
important) results leading up to and including those presented at the recent
Symposium sponsored jointly by the Institute of Quantum Science at Nihon
University and KEK. My task is to present the arguments on light-mass scalar
mesons below 1 GeV from both theory and phenomenological viewpoints, including
the new insight gained on $\pi-\pi$ production and scattering amplitudes.
Specific topics are taken up, particularly on the existence of a
$\sigma$(500-600) as explanation of the twin peak anomaly in $\Upsilon(3S) \to
\Upsilon(1S)\pi\pi$, the status of $J^{PC}=1^{-+}$ states and a possible
crypto-exotic hybrid with $J^{PC}=0^{-+}$ are discussed, as well as the
intriguing enhancement in $p\bar{p}$ radiative decay from $J/\psi$.
