hi! majimak means 'the last.' doeltenikka means 'will be~, so~/be going to be~, so~' For example, "It will be 10 o'clock (when I go home), so you should have dinner first." means "(Naega jibe gamyeon) yeol si ga doeltenikka, ~." And, hasipsio means 'Please, do(be)~.' For example, "(hangbok)hasipsio." means "Please, be happy." I hope you understand well :)
