Evidence for the origin explanationMedium
The November 1999 revised edition was compared on PDF page 61. The spelling and definition were directly compared with the rendered original. It is a general or specialist abbreviation of the time; inclusion does not establish its birth year or period of popular use. Because the source’s English expansion contains an error, only the checked Korean expanded form was written.
