1. The defendant's appeal and the plaintiff's incidental appeal are all dismissed.

2. Costs arising from an appeal and an incidental appeal shall be respectively.

1. The grounds for the defendant's appeal citing the judgment of the court of first instance and the grounds for the plaintiff's incidental appeal are not significantly different from each argument in the court of first instance, and even if each evidence submitted to the court of first instance is presented to this court, the fact-finding and judgment of the court of first instance are justified.

Therefore, the reasoning of the judgment of this court is as follows: (a) evidence added at the trial and submitted by the plaintiff and the defendant are insufficient to recognize each of the allegations by the plaintiff and the defendant, and (b) evidence Nos. 19 through 32 and No. 44 through 59 (including each number) are the grounds of the judgment of the court of first instance, and thus, they are cited in accordance with the main sentence of Article 420 of the Civil Procedure Act.

2. In conclusion, the judgment of the first instance is legitimate, and all the defendant's appeal and the plaintiff's incidental appeal are dismissed. It is so decided as per Disposition.
