We discuss applications of the perturbative QCD approach in the exclusivenon-leptonic two body B-meson decays. We briefly review its ingredients andsome important theoretical issues on the factorization approaches. PQCD resultsare compatible with present experimantal data for the charmless B-meson decays.We predict the possibility of large direct CP asymmetry in $B^0 \to\pi^{+}\pi^{-}$ $(23\pm7 %)$ and $B^0\to K^{+}\pi^{-}$ $(-17\pm5%)$. We alsoinvestigate the Branching ratios, CP asymmetry and isopsin symmetry breaking in$B \to (K^*/\rho) \gamma$ decays and look for the possible new physicscontribution via gluino mediation SUSY which can accomodate the large deviationof $S_{\phi K_s}$ from SM.}
