This contribution is focused on the passive safety of the railway vehicles interiors. The passive safety has become a new area of the rail vehicles design. In the field of rail vehicles interior passive safety the computer simulations are most widely used. The computer simulations must be based on relevant material data. For some common materials (eg. steel, aluminium, etc.) the material data are ascertainable. The interiors of rail vehicles contain quite specific materials frequently. One of the material with more complicated mechanical properties is polyurethane foam (PUR). The aim of this paper is to present validation of material parameters for specific polyurethane foam by experiment. The material properties (for seat made from Elastoflex W 5662 covered with Holdsworth BHLH 31634) will be useful for further simulations.

Summary Background: To evaluate the implementation of the guidelines of the German Society of Phlebology for venous crural ulcer a survey was conducted during the annual meeting of the German Society of Phlebology 2008 in Bochum. Methods: All 719 medical participants got an anonymized questionnaire asking for supply of crural ulcer in their institution. Results: The recurrent 66 questionnaires (9.2%) were filled by colleagues from practice or hospital, mostly surgeons, dermatologists, phlebologists and vascular surgeons. As basic diagnostics vein doppler (56.1%), duplex (75.8%) or measurement of brachial-ankleindex (83.3%) were performed. Compression therapy is used in all institutions. Mainly used wound dressings are polyurethane foam dressings, alginates, hydrocolloids and silver dressings. About 2/3 conduct surgical therapy of ulcers. Conclusion: Supply of ulcus cruris by the participants of the annual meeting of the DGP corresponds mainly, but not in all aspects to the guidelines. Further efforts for a spread of the guidelines are necessary.
