This study was conducted in order to understand factors that would cause second convictions of the property crime and the violent crime committed by juvenile offenders. Even though there have been active researches on what would lead adolescents to commit crimes, because of some legal issues, only a very few number of researches have been carried out in terms of what would cause a second conviction of a juvenile crime. However, in the light of how these second convictions by the juvenile offenders could be developed into other convictions when those offenders are all grown up, it is, now, considered to be necessary to conduct more researches on such matter and to come up with a system to work on the second conviction of the juvenile crimes. As adopting the data mining method, the study conducted a decision tree analysis to look into all those various school, family, peer, psychological and social factors in relation to the second convictions of the property crime and the violent crime, which are considered to cover the greatest percentage of the second conviction of the juvenile offenders. According to the findings of the analysis, in terms of the factors that would cause the second convictions of both the juvenile property crime and violent crime, ‘If this adolescent associates with a delinquent peer’ and ‘If this adolescent goes to school’ appeared to be related to the second convictions of those crimes. In other words, the group of the adolescents who hang around with delinquent peers and who do not go to school as well was understood to be more likely to commit the second convictions of the crimes than the other group that does not meet the requirements is. That led the study to argue for how important it is for any relevant fields to intervene the adolescents’ relationships with the delinquent peers and to encourage the adolescents to keep going to school without giving up their studies. Other than what has been mentioned on the above, these ‘determination for the desistance from delinquency’ and ‘If this adolescent has left school without permission’ turned out to be other factors to be related to the second conviction of the property crime. As for the other factor in connection with the violent crime, the study confirmed that the ‘family’s actual ability to protect’ would cause the second conviction of the juvenile violent crime. As those previous researches which have proved that there is a variety of factors to cause the juvenile crimes argued, this study also pointed out that in order to prevent the second convictions committed by the adolescents, local communities, schools and homes should work together and that this matter will be improved if more people gets interested in the problem with greater attention.

본 연구는 청소년의 재산범죄와 폭력범죄의 재범과 관련된 요인을 파악해보고자 실시되었다. 청소년의 범죄원인에 대한 연구는 활발히 진행되고 있는 반면, 법률적인 문제로 재범에 관한 연구는 극히 제한되어 있는 상태이다. 하지만 청소년의 재범은 성인기의 재범으로 이어질 수 있다는 점에서 많은 연구와 이를 보완할 제도가 필요하다. 그리하여 본 연구는 데이터 마이닝 기법을 활용한 의사결정나무 분석을 통해 청소년의 재범 중 가장 많은 부분을 차지하고 있는 재산범죄와 폭력범죄의 재범과 관련된 다양한 학교·가족·친구·심리·사회적 요인들을 분석하고자 하였다. 분석결과, 청소년의 재산범죄 및 폭력범죄의 재범과 공통적으로 관련된 요인은 ‘비행친구의 유무’와 ‘학교 재학여부’ 인 것으로 나타났다. 즉, 비행친구가 있으면서, 학교를 다니지 않는 집단이 그렇지 않은 집단에 비해 재범 비율이 더 높은 것으로 나타나 비행친구와의 관계조정과 학업 중단 없이 지속적인 학교생활의 중요성에 대해 언급하였다. 이외에 재산범죄의 재범과 관련된 다른 변수는 ‘탈비행 의지’와 ‘무단결석 유무’로 나타났고, 폭력범죄의 재범과 관련된 변수는 ‘가족의 실질적 보호능력’으로 나타났다. 청소년의 범죄에 미치는 요인들이 다양하다는 것을 입증한 기존의 연구들과 마찬가지로 본 연구에서도 청소년의 재범을 예방하기 위해서는 지역사회-학교-가정 모두의 노력이 필요하며, 많은 사람들의 관심과 노력이 필요함을 지적하였다.
