1. All appeals filed by the Defendant (Counterclaim Plaintiff) against the principal lawsuit and counterclaim are dismissed.

2. The costs of appeal shall be principal lawsuit and counterclaim.

The reasoning of the court's reasoning in this case is as stated in the reasoning of the judgment of the court of first instance, and it is cited in accordance with Article 420 of the Civil Procedure Act, since it added that the facts of the court of first instance are insufficient to recognize the defendant's assertion, even if the statements of evidence Nos. 4 through 7 additionally presented in the court of first instance and stand witness E's testimony.

Therefore, the judgment of the court of first instance is legitimate, and all appeals against the defendant's principal lawsuit and counterclaim are dismissed as it is without merit.
