the Prison Service No 1, item 2] Persons with completed higher education work in penitentiary wards of visited establishments. Psychological care is provided by 1-2 per unit (e.g. 2 psychologists per 164 prisoners of the Prison in Kluczbork, 1 psychologist per 218 prisoners in PDC in Grójec). Administration of visited units indicated that the frequent need to transfer prisoners between cells, resulting from a constantly changing number of persons in pre-trial detention and convicts, who should be separately accommodated and the need to separate smokers from non-smokers, made the penitentiary work more difficult. Preventive and educational activity with regard to addictions was carried out in visited establishments (AA meetings, education programmes, short interventions). Administration of establishments signalled problems concerning shortages of staff conducting sessions for persons addicted to intoxicants (e.g. PDC in Grójec).However, in the view of the National Preventive Mechanism, insufficient number of rooms to conduct penitentiary work is a significant problem. For example, in Prison in Kluczbork, the only room to conduct group cultural, sports, preventive, social or religious events was the entertainment room. The situation will improve only after populating the new pavilion. Summing up the results of visits to penitentiary units, we need to mention actions undertaken by the representatives of the National Preventive Mechanism in Prison in Czerwony Bór, aimed at verifying the state of implementation of recommendations issued on 17-18 May 2005. Remarks lodged at that time concerned, among others, capital repairs of one of pavilions, considering the possibility of visits on Sundays and holidays, considering the extension of the visiting time, installing a pay-per-call telephone in each ward of every pavilion, considering the possibility for prisoners to be examined by a general practitioner more frequently than only once a week, making a bathroom available to working persons after their work and increasing the amount of available detergents. After the analysis of arrangements made during the visit to the unit in 2010 it was found that all recommendations issued during the previous visit had been taken into account and implemented. 7.1. Police emergency centres for children A child deprived of family environment inter alia as a result of running afoul of law requires special care and support. Difficult legal situation, detention by te Police officers, interrogation and isolation are a traumatic experience for a young person. These specific circumstances evoke fear, a sense of solitude, uncertainty and depression. A child, whose personality as well as physical and mental maturity are not fully developed, is much more susceptible to maltreatment and any kind of abuse than an adult, especially directly after detention. For that reason, the children rights should be defended regardless of the reason of detention and imprisonment. With a view to well-being of juveniles who are detained by the Police and in order to prevent them from being tortured and subject to any other cruel, inhuman or humiliating treatment or punishment, the National Preventive Mechanism carries out
