We derive various solutions for the gauge field and the gaugino when there are both 5D bulk kinetic terms and 4D brane kinetic terms. Below the compactification scale 1/yc, gauge interaction by the massless mode is universal, independent of the locations of sources, but above 1/yc, the interaction distinguishes their locations. We consider the S1/(Z2× Z2') orbifold compactification, in which N=2 SUSY and SU(2) gauge symmetry break down to N=1 and U(1), respectively. While the odd parity gauge fields under Z2, A1μ and A2μ, interact with the bulk gauge coupling g2, A3μ at low energy interacts with e2g2/(e2+g2) due to the brane kinetic term with the coupling e2. Even if g2, which is asymptotically free, blew up at the scale 1/yc<μ< Λ\rm cutoff, e2g2/(e2+g2) could remain small at low energy by brane matter fields' contribution. The condensations of the gauginos Ψ1 and Ψ2 generate soft mass term of Ψ3 by gravity mediation.
