The Brazilian criminal code has adopted a new list of penalties, with the objective of perfecting the prison sentence and, at the same time, replacing it whenever possible with alternative criminal sanctions such as restraint of freedom, restriction of rights, and fines. The country's Penal Execution Law reflects the United Nations Standard Minimum Rules for Treatment of Prisoners. Brazil uses a semi-open prison system, which combines incarceration with a work program; the costs are lower and chances of prisoner rehabilitation are better. Brazil has undertaken national efforts against organized crime and terrorism and has cooperated in international law enforcement measures through participation in Interpol, bilateral agreements, international conventions, regional treaties, and United Nations agencies. In response to the growing problem of juvenile delinquency, the National Foundation for the Welfare of Minors (FUNABEM) has undertaken many programs to strengthen the family unit and to provide programs that stress social integration. 13 references
