[NTG-context] Prevent hyphenation of the last word on a page

Hello, how to forbid hyphenation of the last word of page? Such that no word is broken onto two consecutive pages like this: page 1: "Diese Unter-" page 2: "brechung ist unschön." I think the question is clear without minexample. Of course I can use \unhyphenated and things like that, but I would like to set this globally. Thanks! Huseyin
