The purpose of this study is to examine, in the discourses concerning juvenile delinquency on
the1990s' major newspapers, the process of subject formation and discoursal devices and its effects
exercised in the process. For this purpose, the study applied Michel Foucault's discourse formation
rules, especially his discoursal object and strategy formation theory. The discourses on juvenile
delinquency have produced various kinds of juvenile delinquencies since the beginning of 1990s.
Among them, this study pays particular attention to the discourses on ‘school bullying,’ which,
combined with other social discourses, have been amplified and expanded, It proved that the
discourses on school bullying formed youth subject into inhumane one. The aspect of ‘school
bullying’ that any juvenile could be victimized without reason was surely an evidence to reveal
juveniles' brutality. Moreover, the fact that anyone could be a victim of ‘school bullying’ called the
attention of not only parents but the public. These discourses caused to establish as a protective
device ‘youth protection law’ within which the youth protection system operated.
However, the social perception that a judical device like the law is imperfect to protect juveniles
asked our society to do careful affection and attention to them. This means that in our society, a big
problem of youth protection arouses the necessity to discipline juveniles's lives. Youth protection as a
new discipline system now appears as a delicate power effect on daily lives. In other words, the
discipline of juveniles's daily lives, that is, bio power, means that the power to control juveniles'
subject has been redeployed.
