The first paper contends that crime prevention programs might more appropriately be based on the public health model of intervention, where research is the core technology, as well as on models of engineering and applied science, where research and development are the core technologies in the selection of interventions. The second presentation provides an overview of major trends in criminological theory and research, followed by a paper that examines vulnerability (exposure to risk, seriousness of victimization consequences, and lack of control) as a key variable in fear of crime. A paper that reports on a victimization survey of 2,000 citizens of Seoul, Korea, considers the incidence of crime in 1990, patterns of crime reporting, victimization risk factors, and citizen's responses to crime. Other papers discuss international experiences with various drug control strategies, juvenile delinquency and juvenile justice in Japan, a model for Korean juvenile delinquency, the future of juvenile justice, the influence of market forces on crime and punishment, and the deinstitutionalization of correctional measures. References accompany some of the papers.
