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

The court's explanation of this case is the same as the reasoning of the judgment of the court of first instance, except for the addition of "the testimony of witness G of the court of first instance is not sufficient to recognize the case" of the 6th 10th e.g., the 6th e.g., the judgment of the court of first instance," and then it is acceptable in accordance with the main sentence of Article 420 of the Civil Procedure Act.

In conclusion, the plaintiff's main claim and the defendant's counterclaim are all dismissed as it is without merit. The judgment of the court of first instance is just in conclusion, and all appeals against the plaintiff's main claim and the defendant's counterclaim are dismissed. It is so decided as per Disposition.
