The result said that the proposition has not been realized in the real world, and actor in case of general subject expresses <Judgement>. On the other hand, actor in the second and the third person it said to occur nuances such as <recommendation><blame>. Basically, the first person can not be used, but judgment at the time of the past, if the actor can be the subject of such first person plural has been described and can co-occur with bekida. Proposition has been realized in the real world, if the actor of specific it said to represents <unreal>. And it said to occur nuances of <regret> is the first person, and <recommendation> <blame> is the second and the third person.
