    Practising dental surgeons are now wearing gloves for longer periods of time than any other comparable group. As part of a study to assess dentists' attitudes to cross-infection, a questionnaire was sent to 1950 randomly selected general dental practitioners in England and Wales, with information being requested concerning the incidence of skin irritation of the hands considered to be associated with glove wearing. The response to the questionnaire was 61%, with 29% of respondents indicating that they had experienced skin irritation. A strong association was identified between pattern of glove wearing and incidence of skin irritation, with routine glove wearers being more likely to suffer skin irritation than occasional glove wearers. Female respondents were also more likely to have experienced skin irritation than male respondents. No association was identified between reported incidence of skin irritation and practising arrangements, years since graduation and number of years of glove wearing.

    Notes:
    Abstract The paper proposes a novel pilot-symbol-aided (PSA) technique for fading compensation of digital signals in the mobile environments. In a PSA system, the data sequence at the transmitter is divided into frames of data. A pilot symbol from a known pseudoradom-symbol sequence is inserted periodically into a frame of data symbol for transmission. In a conventional PSA-receiver, these pilot symbols are extracted from the received signal and used to estimate the effects of signal distortion introduced in the fading channel. The resultant estimates are then used to correct the distortion effects in the received data frames. In the paper, a novel estimation technique that uses the data symbols as well as the pilot symbols is proposed. The technique has the major advantages of simple implementation and short storage-delay time. Results are presented in a series of computer-simulation tests. These assess the effectiveness of the estimation technique on the BER performances of a 16-ary phase-shift keyed (16PSK) and a 16-ary quadrature-amplitude modulated (16QAM) signals in the frequency-selective and frequency-nonselective Rayleigh fading channels. The channels are corrupted by co-channel interference or additive white Gaussian noise. Results of differential-detected 16PSK and star-16QAM signals are also presented for comparison. It has been shown that, the use of PSA technique can significantly improve the bit-error-rate performances of the systems, relative to those using differential detection.
