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

2. The costs of appeal shall be borne by the defendant.

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

Therefore, the reasoning of the judgment of this court is as follows: (a) the witness of the first instance court’s 5th, 13, and 6th and 16th, respectively, shall be considered as the witness of the first instance court; and (b) the “this judgment” of the 9th and 8th, except that the witness of the first instance is deemed as the witness of the first instance court, respectively; and (c) so, it is identical to the reasoning of the judgment of the first instance. Therefore

2. In conclusion, the plaintiff's claim of this case shall be accepted within the scope of the above recognition, and the remaining claims shall be dismissed as they are without merit.

The judgment of the first instance is just based on the conclusion, and the defendant's appeal and the plaintiff's incidental appeal are all dismissed.
