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

2. The costs of appeal are assessed against the Plaintiff.

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

Therefore, the reasoning of the judgment of this court is identical to the reasoning of the judgment of the court of first instance.

2. In conclusion, the plaintiff's claim of this case is justified within the scope of the above recognition and the remaining claims are without merit. Since the judgment of the court of first instance is just in conclusion, the plaintiff's appeal and the defendant's incidental appeal are dismissed as they are without merit. It is so decided as per Disposition.
