We report the current status of RBCK calculations on nucleon structure with both quenched and unquenched lattice &CD. The combination of domain wall fermions and DBW2 gauge action works well for quantities like isovector vector and axial charges, moments of structure functions (ST),, dl, and (l)ap,

We report on the nucleon decay matrix elements with domain-wall fermions in quenched approximation. Results from direct and indirect method are compared with a focus on the process of a proton decaying to a pion and a lepton. We discuss the renormalization necessary for the matching to the continuum
We report on an exploratory study of Nf = 2 dynamical domain wall fermions and the DBW2 gauge action at weak coupling. Details of improved simulation algorithms and preliminary results for the hadron spectrum and renormalised light and strange quark masses will be presented.
