I'm afraid to say that it's generally difficult or impossible to use lenses designed for other camera mounts. Your lens has a Contax-Yashica mount, and the Samsung has a Pentax KAF mount like your K100D.
This is for a variety of reasons, such as wrong or no electrical contacts, essential mechanical couplings, and lens-to-image plane distance - if an adaptor is useable, often the lens sits too far away from the camera and it's no longer possible to focus to infinity.
I may be wrong but I don't think it's possible. Sorry.
It's worth seeing if anyone has a Contax-to-K-mount adaptor, but if it exists, it probably won't allow the camera to focus on anything further than a short distance away. Mounting Pentax lenses on other cameras is easier, as the Pentax mount is short so there's more room for an adaptor.
