Recently, juvenile prostitution in Korea is increasing. The government and civic organizations presented various tough measures designed to fight ever-increasing prostitution involving girls, one of them is a Law on Protection for Juvenile's Sex enacted in June 2000. In comparison with the Anti-Prostitution Law, the law aggravates punishment on adult buying sex from under 19, but regards juvenile involved the prostitution as victims and prescribed protective disposition on prostituted juvenile to the exclusion of criminal punishment to promote reform through education and protection. When we analyzes the criminal-justice-system response to prostituted juvenile. we find the fact that police or prosecutors routinely release most of the prostituted juvenile(about 90% or more) to parents or guardians irrespective of investigation to prostituted juvenile's family environment, personality. and other relevant information. But considering that most of prostituted juvenile have run away from their homes or are from the structural and functional incomplete family, the police and prosecutor's routinized simple return home measure to prostituted juvenile is not seen as an effective measure. Also, juvenile involved in prostitution is difficult to easily overcome by temptation into prostitution for themselves, because they can make a great amount of money, with just the sacrifice of their body and without much excessive labor. On the other hand, in the case of voluntarily entering civil welfare facilities to accommodate prostitutes such as youth rest center, most of them are apt not to stay at there for a long time. Therefore, law enforcement officers are in need of actively making use of protective disposition attempting to harmonized the welfare function and judicial function. But, for the protective disposition to become effective measure to help the rehabilitation of prostituted juvenile needs a variety of changes in juvenile protection and rehabilitation policy. First, juvenile investigator system have to fulfill its function in practice through supplement of competent investigators, the increasement of funds and the development of inquiry technology. Second, treatment of prostituted juvenile are need of deciding centering around community based treatments than institutional treatments. In the order to fulfill functions for community based treatments especially Probation System, the number of the probation officers and volunteer probation officers such as university women students. Also, in case of the Community Service Order and Attendance Center Order, we have to develop the various program of the Attendance Center Order which are suitable and effective to prostituted juvenile and to amend the provision of the Juvenile Law in order that these measures will be applicable to the juvenile under 16 years old. Third, in case of commitment treatment to facilities, commitment to Facility for Guidance and Protection prescribed in the Anti-Prostitution Law abolishes and residential community treatment should actively be applied by juvenile courts. Now, child welfare facilities were supervised by the Ministry of Health and Welfare and youth protective facilities were supervised by Juvenile Court took. There was no governmental agency responsible for supervising the facilities in a consistent manner. Therefore the bureau should establish a special committee for residential community facilities. Lastly, we have to develop the commitment model suitable to prostituted juvenile such as group home and foster home. Fourth, we need to increase the number of the commitment facilities for medical treatment to accommodate the special prostituted juvenile who have disease and so on and to solve the budget-deficits problem.s
