Willie, that doesn't look like a Boyers Knot(Timber Hitch) to me
it's not, it is just what I use for a bowyers knot. the tail reverses around the standing line to double the loop. lots of ways to finish it off depending on how permanent you want to make it. two half hitches is shown in the photo.
bubby is right, in that some knots weaken the line more than others. This hitch in particular is one of the worst for that, but it can be easily untied while under tension. Just plan accordingly...
I do not expect that google would help you with what is a local name for a commonly used knot around here. Just don't know what the rest of the world calls it.
actually the gangion knot and the korean knot, as shown in Loon's pic, are very similar. basically a slip knot with the running end tucked back into the knot a bit differently.
