  We present results from a dispersion--relation investigation on a
coupled--channel analysis of $\bar{K}N$--initiated processes in the low-- and
intermediate--energy region. The analysis demonstrates both the effectiveness
of these relations to constrain the parameters of the unmeasurable ${\pi}Y$
channels and the need for better data in the low--energy region, such as could
be provided at a $\phi$--factory. (pres. by G.V. at the "International Workshop
on the Spectoscopy of Hypernuclei", Sendai, Japan, January 8-10, 1998, to be
publ. in Genshikaku Kenkyuu).
