Recent NA48 Results on Semileptonic and Rare Kaon Decays:. Measurement of VUS

The new results of investigation of K_L⁰e3 and K^±e3 decays performed by NA48 Collaboration are presented. The measured branching fractions are used to extract V_us. The values of Ke3 form-factors and radiative K_L⁰e3γ branching ratio are reported. A list of recent NA48 results concerning some rare neutral kaon decays is given.
