Popis:	We study the $s-\bar s$ asymmetry in the nucleon sea using a model in which the proton wave function includes a Kaon-Hyperon Fock state. Parameters of the model are fixed by fitting the $s-\bar s$ asymmetry obtained from global fits to Deep Inelastic Scattering data. We discuss possible effects of the $s-\bar s$ asymmetry on the measurement of the Weinberg angle by the NuTeV Collaboration. Comment: 6 pages, 2 figures
