한국 남자 청소년의 범죄지속 위험예측 요인분석 : 데이터마이닝 의사결정나무 적용

This study utilizes data regarding the environment of Korean juvenileoffenders nationwide sent to the Juvenile Classification Office in 1998 and theircriminal history from 1998 to December 2009 to propose a model predicting riskof juvenile crime continuation and relevant rules based on the populationheterogeneity perspective. The risk of crime continuation was the highest incases with low 'intelligence quotient', past 'runaway experience', and acrime-prone 'growth area'. The risk was second highest in a combination withlow 'intelligence quotient', past 'runaway experience', 'growth area' located in aresidential neighborhood, and a single parent family. From the fact that evenwith low IQ the risk of crime continuance was low if there was no runawayexperience, it can be argued that there is an urgent need for the government'ssupport measures for runaway juveniles. This study has an academic andpolitical significance in that it demonstrates at the cause of crime continuationby theoretically examining developmental criminology and identifies the causeand risk factors of Korean adolescents' crime continuation by analyzing theircross-sectional and longitudinal criminal records. Applying the risk predictionmodel from this study to corrective training programs will prevent the Koreanadolescents' habituation of crime in advance.
