The demographic factors, characteristics of crime, psychiatric diagnoses and psychiatric opinions and legal opinions , and legal opinions were analyzed and the results are as follows. 1) The frequency of crimes by female, high education level and single status increased. 2) As to the psychiatric diagnosis, schizophrenia decreased whereas substance- use disorder, mood disorder and personality disorder were increased and kleptomania and anxiety disorder were added. 3) As to the types and feature of crime, homicide and violence increased, whereas arson decreased and larcency, violation of harzadous substance and violation of narcotic drug were added. 4) As to victims of crime, the frequency of crimes committed to strangers increased whereas that of the family members and their lelatives were decreased. 5) As to motivation of crime, the frequency of impulsivity increased but psychotic symptoms such as delusion and hallucination significantly decreased. 6) More that half of psychiatric tests were referred from the court, but the agreement rate between the judge 's opinions and psychiatric opinions was decreased. In Conclusion, the changes of charateristics of mentally ill criminal were attributed to sociocultural changes for mentally ill criminals and implimeted in Social Protection Law.
