The Universal Mobile Telecommunications System (UMTS)is a concept for a third generation mobile telecommunications system fiom the RACE 1043 project. As well as support for a 'universal' high quality voice service, UMTS is targeted to support a wide range of services from paging, facsimile and data file transfer to 'high' bit rate services, including videotelephony and some Broadband-ISDN services. Following on from research work undertaken in the first three years of the project in specialised technical working groups, this paper presents work to combine the individual results and conclusions made towarak a UMTS 'system framework! Primarily the contribution concentrates on user requirements, the adaptivity requirements and resulting detail of the lower layers of the radio interface, and comiders some deployment issues with reference to an 'example town!

Placebo respiratory devices, such as inhalers, large volume spacers and peak flow meters provide reli able methods of teaching patients effective drug able methods of teaching patients effective drug delivery techniques and monitoring compliance and treatment progress. Concern has been raised that using such demonstration devices on more than one person may expose patients to the risk of cross-infection with pathogenic organisms. The lack of regulation and guidance on the use and decontamination of placebo devices prompted us to complete a risk assessment, examining the likelihood and consequence of acquisition of pathogens and resultant illness in our respiratory patient group.
