The purpose of this thesis is to examine software licensing, how a software developer can benefit from it and to define specifications for licensing system of software based medical technology product. The thesis has been divided into theoretical and empirical parts. In the theoretical part the concept of software licensing and different aspects that are connected to it are examined with a help of research material. On the ground of this research, in the empirical part, a licensing system for a medical software product called iCentral is designed. The empirical part is based on interviews, questionnaire and on authors own experience gained while working for the case-company.The thesis has great practical importance for the case-company by proposing both an ideal, and more importantly, practical implementation for a licensing system of a product. Thesis shows that electronic licensing is a viable option to sell medical technology products without a need to revise existing procedures or the enterprise resource system in the case company.

We have tested an alternative method of delivering health services to regional areas of Queensland. By integrating telepaediatrics into an existing outreach programme for children with diabetes and endocrine conditions, we were able to reduce travel for specialist hospital staff while maintaining (and sometimes increasing) the contact patients had with the specialist team. In the first 28 months, we facilitated 160 patient consultations and 10 education sessions via videoconference through the telepaediatric service. By the end of the study, site visits were taking place annually and routine videoconference clinics were scheduled quarterly for the review of new patients and follow-up. Telepaediatric services in endocrinology and diabetes were established at three levels: the coordination of routine specialist clinics via videoconference; ad hoc patient consultations for collaborative management during acute presentations and at times of urgent clinical need; and the delivery of education to staff and patients throughout the state. The net result was improved access to specialist services from rural and remote areas of Queensland.

We compared the costs incurred by families attending outpatient appointments at the Royal Children's Hospital (RCH) in Brisbane with those incurred by families who had a consultation via videoconference in their regional area. In each category 200 families were interviewed. The median time spent travelling for videoconferences was 30 min compared with 80 min for face-to-face appointments. Families interviewed in the outpatient department had travelled a median distance of 70 km, while those who had a videoconference at the local hospital had travelled only 20 km. It cost these families much more to attend an appointment at the RCH than to attend a videoconference. Ninety-six per cent of families (193) reported at least one of the following types of expense: 150 families had expenses related to parking (median A$10), 156 had fuel expenses (median A$10) and 122 reported costs related to meals purchased at the RCH (median A$10). Only 21 families who had their appointment via local videoconference reported any additional costs. Specialist appointments via videoconference were a more convenient and cheaper option for families living in regional areas of Queensland than the conventional method of attending outpatient appointments at the specialist hospital in Brisbane.

The mechanical properties of a range of agglomerates and particulate coatings have been measured using a nanoindenter. The effect of formulation properties such as powder and binder properties on coating hardness is described. An attempt is also made to measure the fracture hardness with the nanoindenter. The use of indentation technology to measure fundamental agglomerate properties is critically analysed. Based on the indentation measurements and standard attrition test results, the coating hardness is found closely related to the attrition rate under standard conditions and can be used to screen different powder/binder formulations.

Particle flow patterns were investigated for wet granulation and dry powder mixing in ploughshare mixers using Positron Emission Particle Tracking (PEPT). In a 4-1 mixer, calcium carbonate with mean size 45 mum was granulated using a 50 wt.% solution of glycerol and water as binding fluid, and particle movement was followed using a 600-mum calcium hydroxy-phosphate tracer particle. In a 20-1 mixer, dry powder flow was studied using a 600-mum resin bead tracer particle to simulate the bulk polypropylene powder with mean size 600 mum. Important differences were seen between particle flow patterns for wet and dry systems. Particle speed relative to blade speed was lower in the wet system than in the dry system, with the ratios of average particle speed to blade tip speed for all experiments in the range 0.01-015. In the axial plane, the same particle motion was observed around each blade; this provides a significant advance for modelling flow in ploughshare mixers. For the future, a detailed understanding of the local velocity, acceleration and density variations around a plough blade will reveal the effects of flow patterns in granulating systems on the resultant distribution of granular product attributes such as size, density and strength.
