1. The plaintiffs' appeals and extended claims are all dismissed.

2. After an appeal is filed.

The reasoning of the court's reasoning in this case is as follows: (a) although the result of the fact-finding on Gap evidence No. 8's video and voice, so-called "A" medical corporations, Busan National University Hospital, Busan National University Hospital, Nam-gu Busan National University Hospital, Nansan National University Hospital, and Yangsan National University Hospital, the fact-finding on the first instance court's facts-finding or the fact-finding on the plaintiffs' assertion is not sufficient, it is identical to the reasoning of the judgment of the first instance, and thus, it is cited pursuant to Article 420 of the Civil Procedure Act.

Therefore, the judgment of the court of first instance is legitimate. Thus, the plaintiffs' appeal and the claim added or expanded in the court of first instance are dismissed as it is without merit.
