1. The court's explanation concerning this case is the same as the reasoning of the judgment of the first instance.

According to the results of fact-finding by the court of first instance, the National Health Insurance Corporation, and the National Pension Management Corporation, the defendant can recognize the fact that the plaintiffs paid the plaintiffs' health insurance premiums and national pension even during the period in which the plaintiffs were the representative director or the executive director, and instead, it is difficult to change the facts and judgments recognized by the court of first instance even if the above evidence was neglected.

2. In conclusion, the judgment of the first instance is legitimate, and the defendant's appeal is dismissed in entirety.
