-느라고 + result clause

(reportworld.co.kr) [...] This paper aims to distinguish foreground and background of the grammatical meaning, and on this basis, to present a method describing some aspectual connective endings. First, I insist that the distinction between foreground and background in discourse pragmatics should be applied to not only textual or sentential informations, but also lexical and grammatical meanings. I recognize that -eumyeonseo(-으면서), -neurago(-느라고), -goseo(-고서), -jamaja(-자마자) have two kinds of meaning component: one is relational component(between two clauses) such as simultaneity, cause, preceding, succession and the other is aspectual component such as perfective, imperfective. Their aspectual meaning components cannot function as focus of answer, while their relational components can. I argue that this difference can be described in terms of foreground and background. That is, their relational meanings are foreground meanings while their aspectual meanings are background ones.
