A Pervasive Technology Solution for Diabetes Using Gestational Diabetes as a Model

Diabetes is one of the leading chronic diseases affecting Australians and its prevalence continues to rise. Diabetes is therefore becoming a serious challenge for both the quality of healthcare and expenditure in the Australian healthcare system. The goal of this study is to investigate the development and application of a pervasive wireless technology solution to facilitate the effective management of diabetic patients, using the context of the care of women with gestational diabetes, a form of diabetes that affects up to 8% of pregnant women as a test case. Integral to the success of this solution is the unique software technology developed by INET to enable mobile phones to facilitate superior diabetes self-management

Mathematical pathways for students articulating to Business degrees

Australia needs more qualified professionals in the STEM areas. The national focus on widening participation in higher education (HE) includes strengthening pathways from vocational education and training (VET). VET students often lack the mathematics skills necessary to articulate successfully to their chosen degrees. Maths anxiety has been identified as a barrier to success in Business degrees in particular (Joyce, Hassal, Jose, Donose & Jose, 2006), highlighting the need for maths knowledge and support for students transitioning to these degrees. Of particular concern are those students who might be potentially less prepared for the transition, such as VET students. This project is part of a larger Office for Learning and Teaching grant focusing on developing contextualised pathways for four different disciplines (education, engineering, business and health science). The business pathway mapped mathematics topics covered in VET units associated with business qualifications at Certificate 3, 4 and Diploma level foundation level units to the base level maths knowledge required at the University of Tasmania and the University of Notre Dame Australia for completion of first year quantitative methods units. From this mapping, a set of online modules were developed to support students during their VET qualifications with foundation level skills, and fill the mathematics gap between VET and HE. These modules were also designed to provide support to first year business students, and assist them in completion of the quantitative methods units required in first year Bachelor of Business Degrees. The pathway developed has seven modules; two foundation level modules, three transition level modules and two providing resources for support through HE quantitative methods. For the first five modules, a pre-test determined whether a student needed to complete the module and a post-test (self-assessed) was developed to test the students’ knowledge after completing the module lessons, practice tasks and exercises. The project has recently concluded, and the pathway to business has now been active for 4 months during which it has been offered to first year business students at the University of Tasmania to trial. Successful completion of the module post-tests has been endorsed by the University of Notre Dame Australia’s School of Business for entry into the program for students with tertiary maths. This presentation describes the process of the business pathway development and the opportunities for cross sectoral course support and delivery.

The effect of laser remelting on the surface chemistry of Ti6al4V components fabricated by selective laser melting

Surface remelting/skin scanning of components is generally performed during the selective laser melting (SLM) process to improve the surface quality of a part. However, the chemical effects of surface remelting are not well understood. In this study, cuboidal parts fabricated with and without laser remelting were characterised using scanning electron microscopy (SEM), surface profilometry and X-ray photoelectron spectrophotometry (XPS). The SEM images showed a low-amplitude undulating pattern was observed on both surfaces. The surface chemistries of the surface remelted/skin scanned (SK) and non-surface remelted/non-skin scanned (NSK) samples were observed to significantly differ in their elemental composition. The thickness of the surface oxide layer of the SK surface was double that of the NSK surface. Also, the contribution of the major alloying elements, including titanium and aluminium, on the surface oxide layer varied for both NSK and SK surfaces. The surface chemistry of the NSK and SK surface was significantly different to a conventionally forged (CF) Ti6Al4V surface. The rate of decrease of oxide with depth was in the order of CF > NSK > SK. Although surface remelting is useful in rendering improved surface quality, its impact on surface chemistry should be carefully considered

Functionalisation of Ti6Al4V components fabricated using selective laser melting with a bioactive compound

Surface modification of an implant with a biomolecule is used to improve its biocompatibility and to reduce post-implant complications. In this study, a novel approach has been used to functionalise phosphonic acid monolayers with a drug. Ti6Al4V components fabricated using selective laser melting (SLM) were functionalised with Paracetamol (a pharmaceutically relevant biomolecule) using phosphonic acid based self-assembled monolayers (SAMs). The attachment, stability of the monolayers on the SLM fabricated surface and functionalisation of SAMs with Paracetamol were studied using X-ray photoelectron spectroscopy (XPS) and surface wettability measurements. The obtained results confirmed that SAMs were stable on the Ti6Al4V surface for over four weeks and then began to desorb from the surface. The reaction used to functionalise the phosphonic acid monolayers with Paracetamol was noted to be successful. Thus, the proposed method has the potential to immobilise drugs/proteins to SAM coated surfaces and improve their biocompatibility and reduce post-implant complications

Effects of antiplatelet therapy on stroke risk by brain imaging features of intracerebral haemorrhage and cerebral small vessel diseases: subgroup analyses of the RESTART randomised, open-label trial

Background Findings from the RESTART trial suggest that starting antiplatelet therapy might reduce the risk of recurrent symptomatic intracerebral haemorrhage compared with avoiding antiplatelet therapy. Brain imaging features of intracerebral haemorrhage and cerebral small vessel diseases (such as cerebral microbleeds) are associated with greater risks of recurrent intracerebral haemorrhage. We did subgroup analyses of the RESTART trial to explore whether these brain imaging features modify the effects of antiplatelet therapy
