We investigate the tunneling conductance and the supercurrent through a quantum dot which is placed in the normal region and coupled to superconducting leads. We provide quantitative and qualitative descriptions as well: show that conductance displays a resonant behaviour and Josephson current exhibits sign, periodic oscillations.
