| 1 | Longwall automation: Delivering enabling technology to achieve safer and more productive underground mining显示文摘The ongoing need to deliver improved safety, productivity and environmental benefit in coal mining presents an open challenge as well as a powerful incentive to develop new and improved solutions.This paper assesses the critical role that enabling technologies have played in the delivery of remote and automated capability for longwall mining. A brief historical account is given to highlight key technical contributions which have influenced the direction and development of present-day longwall technology. The current state of longwall automation is discussed with particular attention drawn to the technologies that enable automated capability. Outcomes are presented from an independently conducted case study that assessed the impact that CSIRO's LASC longwall automation research has made to the longwall mining industry in Australia. Importantly, this study reveals how uptake of this innovative technology has significantly benefitted coal mine productivity, improved working conditions for personnel and enhanced environmental outcomes. These benefits have been widely adopted with CSIRO automation technology being used in 60 per cent of all Australian underground operations.International deployment of the technology is also emerging. The paper concludes with future challenges and opportunities to highlight the ongoing scope for longwall automation research and development. | Ralston Jonathon C. Reid David C. Dunn Mark T.

| 5 | Absolute cardiovascular risk assessment by Australian early-career general practitioners: a cross-sectional study显示文摘Objective To determine the prevalence and associations of general practice registrars’performing absolute cardio-vascular risk(ACVR)assessment(ACVRa).Design A cross-sectional study employing data(2017–2018)from the Registrar Clinical Encounters in Training project,an ongoing inception cohort study of Australian GP registrars.The outcome measure was whether an ACVRa was performed.Analyses employed univariable and multivariable regression.Analysis was conducted for all patient problems/diagnoses,then for an‘at-risk’population(specific problems/diagnoses for which ACVRa is indicated).Setting Three GP regional training organisations(RTOs)across three Australian states.Participants GP registrars training within participating RTOs.Results 1003 registrars(response rate 96.8%)recorded details of 69105 problems either with Aboriginal and/or Torres Strait patients aged 35 years and older or with non-Indigenous patients aged 45 years and older.Of these problems/diagnoses,1721(2.5%(95%CI 2.4%to 2.6%))involved an ACVRa.An ACVRa was‘plausibly indicated’in 10384 problems/diagnoses.Of these,1228(11.8%(95%CI 11.2%to 12.4%))involved ACVRa.For‘all problems/diagnoses’,on multivariable analysis female gender was associated with reduced odds of ACVRa(OR 0.61(95%CI 0.54 to 0.68)).There was some evidence for Aboriginal and/or Torres Strait Islander people being more likely to receive ACVRa(OR 1.40(95%CI 0.94 to 2.08),p=0.10).There were associations with variables related to continuity of care,with reduced odds of ACVRa:if the patient was new to the registrar(OR 0.65(95%CI 0.57 to 0.75)),new to the practice(OR 0.24(95%CI 0.15 to 0.38))or the problem was new(OR 0.68(95%CI 0.59 to 0.78));and increased odds if personal follow-up was organised(OR 1.43(95%CI 1.24 to 1.66)).For‘ACVRa indicated’problems/diagnoses,findings were similar to those for‘all problems/diagnoses’.Association with Aboriginal and/or Torres Strait Islander status,however,was significant at p<0.05(OR 1.60(95%CI 1.04 to 2.46))and association with female gender was attenuated(OR 0.88(95%CI 0.77 to 1.01)).Conclusion Continuity of care is associated with registrars assessing ACVR,reinforcing the importance of care continuity in general practice.Registrars’assessment of an individual patient’s ACVR is targeted to patients with individual risk factors,but this may entail ACVRa underutilisation in female patients and younger age groups. | Toby Morgan Anna Ralston Andrew Davey Elizabeth G Holliday Mark Nelson Alison Fielding Mieke van Driel Amanda Tapley Dominica Moad Jean Ball Jennifer Presser Neil Spike Parker Magin | 2023 | Family Medicine and Community Health2023，11，3： | 0 |
