The defendant's appeal is dismissed.

1. The summary of the grounds for appeal (e.g., imprisonment with prison labor for six months) of the lower court is too unreasonable.

2. Although there are extenuating circumstances, such as the fact that the defendant acknowledges his mistake and reflects on the fact that the defendant committed the crime of this case, which inflicts bodily injury on the victim who was detained in prison without being aware of even though he was in prison, the defendant committed the crime of this case, the degree of injury caused by the crime of this case, and the victim is not easy, and the victim is punished, and the defendant has the records of punishment several times due to violent crimes, and other various sentencing conditions indicated in the records, such as the defendant's motive and background leading up to the crime of this case, the situation after the crime, and the age, character, and environment of the defendant, are considered, it cannot be deemed that the sentence imposed by the court below is too unreasonable. Thus, the above argument of the defendant is without merit.

3. In conclusion, the defendant's appeal is dismissed in accordance with Article 364 (4) of the Criminal Procedure Act since it is without merit. It is so decided as per Disposition.
