1. The plaintiffs' appeal is dismissed.

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

The purport of the claim and appeal is the purport of the appeal.

1. The grounds for appeal by the plaintiffs citing the judgment of the court of first instance are not significantly different from the allegations in the court of first instance, and even if evidence submitted in the court of first instance shows evidence submitted to this court, the fact-finding and judgment of the court of first instance are recognized as legitimate (it is not equipped with safety facilities (prevention and treatment, safety loss, etc.) recommended by the Ministry of Health and Welfare to the above toilet at the time when the network A was involved in an accident beyond a hospital. However, the evidence submitted by the plaintiffs alone is insufficient to find that "the defendant did not remove the water level of the above toilet floor" or "the defendant caused the above accident by negligence that did not install the above safety facilities within the toilet or the above safety facilities within the toilet", and there is no other evidence to find otherwise. Rather, in light of the above evidence, it is deemed that there is no other evidence to acknowledge this differently. The reason for the judgment of the court of first instance is identical with the reason for the judgment of the court of first instance and thus, it is cited as it is under the main text of Article 420 of the Civil Procedure Act.

2. The appeal by the plaintiffs is dismissed on the grounds that the appeal by the plaintiffs is without merit. It is so decided as per Disposition.
