§ 1 of the Youth Act determines the purpose "help to grow healthy boys." The state, society and the family should be responsible for developing and growing young people as a member of a healthy social boy. Korea and the countries in the world apply against the adolescent not the responsible penalties but the protection and treatment as an important means of treatment. So many countries nehemn the idea "protection of teenagers", which target young people to grow into a healthy community members. However, the educational ideas are presented critical views, which can be a violation of the rights to be assured to the boy. Thus, the idea "protection of the young people" of the youth law is to be realized by guarantees and guarantees of the Due Process. For the realization the due process introduces and carries out `state support`, if no case the private assistance exists. Korea, like Japan, should also lay down guiding rules for the operation of the assistance.
