ArtEMon: Artificial Intelligence and Internet of Things Powered Greenhouse Gas Sensing for Real-Time Emissions Monitoring.

Greenhouse gas (GHG) emissions reporting and sustainability are increasingly important for businesses around the world. Yet the lack of a single standardised method of measurement, when coupled with an inability to understand the true state of emissions in complex logistics activities, presents enormous barriers for businesses to understanding the extent of their emissions footprint. One of the traditional approaches to accurately capturing and monitoring gas emissions in logistics is through using gas sensors. However, connecting, maintaining, and operating gas sensors on moving vehicles in different road and weather conditions is a large and costly challenge. This paper presents the development and evaluation of a reliable and accurate sensing technique for GHG emissions collection (or monitoring) in real-time, employing the Internet of Things (IoT) and Artificial Intelligence (AI) to eliminate or reduce the usage of gas sensors, using reliable and cost-effective solutions.

ParcEMon: IoT Platform for Real-Time Parcel Level Last-Mile Delivery Greenhouse Gas Emissions Reporting and Management.

Transport is Australia's third-largest source of greenhouse gases accounting for around 17% of emissions. In recent times, and particularly as a result of the global pandemic, the rapid growth within the e-commerce sector has contributed to last-mile delivery becoming one of the main emission sources. Delivery vehicles operating at the last-mile travel long routes to deliver to customers an array of consignment parcels in varying numbers and weights, and therefore these vehicles play a major role in increasing emissions and air pollutants. The work reported in this paper aims to address these challenges by developing an IoT platform to measure and report on real-world last-mile delivery emissions. Such evaluations help to understand the factors contributing to freight emissions so that appropriate mitigation measures are implemented. Unlike previous research that was completed in controlled laboratory settings, the data collected in this research were from a delivery vehicle under real-world traffic and driving conditions. The IoT platform was tested to provide contextualised reporting by taking into account three main contexts including vehicle, environment and driving behaviours. This approach to data collection enabled the analysis of parcel level emissions and correlation of the vehicle characteristics, road conditions, ambient temperature and other environmental factors and driving behaviour that have an impact on emissions. The raw data collected from the sensors were analysed in real-time in the IoT platform, and the results showed a trade-off between parcel weight and total distance travelled which must be considered when selecting the best delivery order for reducing emissions. Overall, the study demonstrated the feasibility of the IoT platform in collecting the desired levels of data and providing detailed analysis of emissions at the parcel level. This type of micro-level understanding provides an important knowledge base for the enhancement of delivery processes and reduction of last-mile delivery emissions.

Need for Additional Glaucoma Surgery and Complications Following Glaucoma Drainage Device Surgery.

PRCIS: In this longitudinal study of patients with open-angle (OAG), pseudoexfoliative (PXE), or neovascular glaucoma (NVG) receiving glaucoma drainage devices (GDD), posttube cumulative rates of reoperation, corneal graft, and visually threatening complications (VT-complications) increased beyond 5 years and were not significantly affected by glaucoma type. PURPOSE: To study the need for additional glaucoma surgery and development of complications after first GDD surgery in eyes with primary OAG, PXE, or NVG glaucoma. PATIENTS AND METHODS: There were 306 eyes with OAG (n=185), PXE (n=60), or NVG (n=61) glaucoma who received a first GDD between 1996 and 2017. Outcomes including glaucoma reoperation, corneal graft procedure, and VT-complications after GDD were measured. Kaplan-Meier analysis was used to compare cumulative rate of reaching outcomes over time after GDD placement among the 3 glaucoma groups. RESULTS: When comparing the OAG, PXE, and NVG groups, there were no significant differences in post-GDD cumulative rates of reoperation (P=0.33), corneal graft (P=0.26), or VT-complications (P=0.65) over time. For all eyes, the overall cumulative rates for each outcome measure increased beyond 5 years, and specific Kaplan-Meier rates (5-y, 10-y) included: reoperation (16%, 25%), corneal graft (6%, 12%), VT-complications (9%, 14%). When comparing specific GDDs, the Ahmed FP7 had a higher cumulative reoperation rate over time compared with the Baerveldt 350 (P=0.019). CONCLUSION: Glaucoma type did not significantly affect post-GDD cumulative rates of reoperation, corneal graft, and VT-complication among the OAG, PXE, and NVG groups. For all eyes, cumulative rates of reoperation, corneal graft, and VT-complications increased beyond 5 years. The Ahmed FP7 had a significantly higher cumulative reoperation rate compared with the Baerveldt 350 over time.

Rate of Corneal Grafting Post-Glaucoma Drainage Device Use in Pediatric and Adult Patients.

PRCIS: Kaplan-Meier analysis was used to compare the rate of corneal grafting after glaucoma drainage device (GDD) placement in pediatric and adult patients. Adults were at an increased risk of receiving a corneal graft after device placement. PURPOSE: The goal of this study was to compare the rate of corneal graft implantation after GDD placement in pediatric and adult patients. PATIENTS: Patients receiving a GDD between January 1, 1985 and December 31, 2017 were selected from the medical records. Patients receiving their first device while <18 years of age were considered children for the extent of the study. METHODS: We compared the rate of receiving a corneal graft after GDD implantation using Kaplan-Meier analysis. Baseline patient characteristics and surgical characteristics were compared using a generalized estimating equation. RESULTS: Corneal grafting occurred in 8.6% of adults and 4.7% of children from the original cohort. The rate of receiving a corneal graft at 5, 10, and 15 years was 9.4%, 16.8%, 39.4% and 1.6%, 1.6%, 12.5% for adults and children, respectively. However, certain characteristics were different between the 2 groups. CONCLUSION: Adult patients were more likely to receive a corneal graft after GDD placement. However, pediatric and adult patients differed in the prevalence of preexisting corneal disease, glaucoma type, GDD type used, and types of previous surgeries. Elucidation of the impact of these factors on corneal graft rate requires a larger cohort size.

Enhancing user acceptance of mandated mobile health information systems: the ePOC (electronic point-of-care project) experience.

From a clinical perspective, the use of mobile technologies, such as Personal Digital Assistants (PDAs) within hospital environments is not new. A paradigm shift however is underway towards the acceptance and utility of these systems within mobile-based healthcare environments. Introducing new technologies and associated work practices has intrinsic risks which must be addressed. This paper contends that intervening to address user concerns as they arise throughout the system development lifecycle will lead to greater levels of user acceptance, while ultimately enhancing the deliverability of a system that provides a best fit with end user needs. It is envisaged this research will lead to the development of a formalised user acceptance framework based on an agile approach to user acceptance measurement. The results of an ongoing study of user perceptions towards a mandated electronic point-of-care information system in the Northern Illawarra Ambulatory Care Team (TACT) are presented.
