Query: Kaon Productions Off Nucleons And The Structure of Baryon Resonances   The recent Investigations in the chiral quark model show that kaon
productions of nucleon play an important role in understanding the structure of
baryons. The evidences of a third $S_{11}$ resonance in the second resonance
region and two narrow states around 2 GeV suggest a set of the molecular type
baryons with hidden strangeness. Confirming these states requires further
theoretical and experimental studies of the strangeness production.
