Models are constructed and studied for the low-energy interactions in each of two hadronic systems, the KN and the πN. In the low-energy KN system, there appears the resonance Λ(1405); in the low-energy πN system, the resonance Δ(1232). Each of the models is so constructed that the corresponding resonance appears, not merely as a composite state of the hadrons in the system in which it is formed, which is how it appears in older and more conventional models, but as a state to which there is also a contribution from the constituent quarks. The models for the KN interaction is studied primarily with a view to explaining the recent and unexpected kaonic H-atom result - something which no existing model is able to do. The model for the πN interaction is used to study πN scattering in the (3,3) channel.
