In this paper, we discuss a project to develop a system that supports mobile wireless devices for visiting nurses, in place of an existing paper-based system. The wireless system allows nurses to securely access, update and query a central database containing patient information. One of the applications developed for this project is supplies management, where nurses can, during regular client visits, order replenishment stock to be delivered to the site by a supplier. We describe the detailed development of an “As-Is” business process map, leading to a significantly improved “To-Be” process to realize the expected benefits. A model of the ordering/logistics process was also developed, to evaluate...

CEFS compensates for the broadened tuning curves and elevated thresholds of an impaired ear by adjusting the relative amplitudes of the formants without distorting the spectral envelope between the formants. Multiband compression, on the other hand, has been utilized in hearing aids to compensate for the reduced dynamic range of the impaired ear.

In the case of reduced spontaneous input to a region of a LIN, the edges between the normal and abnormal spontaneous input will be enhanced in the LIN's output. In LINs within the central auditory system, regional reduction of spontaneous input may occur because of deafferentation resulting from a peripheral hearing loss. A model of auditory LINs is developed to investigate how such abnormal spontaneous edges in LIN outputs could be related to tinnitus, the phantom perception of sounds.

This study characterized the autonomic response to rectal distension in IBS using baroreceptor sensitivity (BRS), a measure of autonomic function. Rectal bag pressure, discomfort, pain, ECG, blood pressure and BRS were continuously measured before, during and after rectal distension in 98 healthy volunteers (34 +/- 12 years old, 52 females) and 39 IBS patients (39 +/- 11 years old, 35 females). In comparison with the healthy volunteers, IBS patients experienced significantly more discomfort (69 +/- 2.2% vs 56 +/- 3.6%; P < 0.05), but not pain (9 +/- 1.4% vs 6 +/- 2.4%; ns) with rectal distension despite similar distension pressures (51 +/- 1.4 vs 54 +/- 2.4 mmHg; ns) and volumes (394 +/- 10.9 vs 398 +/- 21.5 mL; ns). With rectal distension, heart rate increased in both healthy volunteers (66 +/- 1 to 71 +/- 1 bpm; P < 0.05) and IBS patients (66 +/- 2 to 74 +/- 3 bpm; P < 0.05). Systolic blood pressure also increased in both healthy volunteers (121 +/- 2 to 143 +/- 2 mmHg; P < 0.05) and patients (126 +/- 3 to 153 +/- 4 mmHg (P < 0.05) as did diastolic blood pressure, 66 +/- 2 to 80 +/- 2 mmHg (P < 0.05), compared with 68 +/- 3 to 84 +/- 3 mmHg (P < 0.05) in IBS patients. The systolic blood pressure increase observed in IBS patients was greater than that seen in healthy volunteers and remained elevated in the post distension period (139 +/- 3 mmHg vs 129 +/- 2 mmHg; P < 0.05). IBS patients had lower BRS (7.85 +/- 0.4 ms mmHg(-1)) compared with healthy volunteers (9.4 +/- 0.3; P < 0.05) at rest and throughout rectal distension. Greater systolic blood pressure response to rectal distension and associated diminished BRS suggests a compromise of the autonomic nervous system in IBS patients.
