We review the one-loop corrections to the partial decay width of
sbottom-quark into a top quark and a chargino for the parameter space relevant
to the TESLA e+e- linear collider. We present the results available in the
literature for the QCD and the Yukawa coupling corrections in a unified
framework. In this way a direct comparison of the size of the various
corrections is possible.Comment: LaTeX, 11 pages, 7 figures included. Talk presented at the 2nd
