It looks like they've been having a few taste tests of the new shot and maybe talking about how hangovers effect job performance in Korea or finding out how the new shot improves that performance. Either their having another taste test then or that will be the date of the last one. On the link you provided their asking for peoples personal information (subjects to try it on)?
