This title addresses various theoretical, phenomenological, and experimental issues concerning quark and lepton masses and mixings, which are central to solving the long-standing fermion mass problem.The focus is the presentation of the status of the main accelerator and non-accelerator neutrino mass experiments, such as Super-Kamiokande, and SNO, the future experimental projects, e.g., MINOS, and some of the phenomenology related to them. Also included are reviews of the theoretical and phenomenological ideas related to the tests of the direct CP violating effects that are expected to occur in both the K and the B meson systems, including discussions of future experimental projects.
