Kime is Japanese. I believe in Korean they just use "him" (ķ) which translates as power, force or strength. That's the only term I've heard Kukkiwon instructors use on courses.
It's not power per se, but pointed power. The power you intend. For instance if you throw a push kick but intended a thrust kick, you failed. So something like pointed and profound power output is how I view kime.
