A Hybrid Agent-Based And Equation Based Model For The Spread Of Infectious Diseases, Elizabeth Hunter, Brian Mac Namee, John D. Kelleher
A Hybrid Agent-Based And Equation Based Model For The Spread Of Infectious Diseases, Elizabeth Hunter, Brian Mac Namee, John D. Kelleher
Articles
Both agent-based models and equation-based models can be used to model the spread of an infectious disease. Equation-based models have been shown to capture the overall dynamics of a disease outbreak while agent-based models are able to capture heterogeneous characteristics of agents that drive the spread of an outbreak. However, agent-based models are computationally intensive. To capture the advantages of both the equation-based and agent-based models, we create a hybrid model where the disease component of the hybrid model switches between agent-based and equation-based. The switch is determined using the number of agents infected. We first test the model at …

SURE Journal: Science Undergraduate Research Experience Journal
Background: A child’s weight status can allow health care professionals to assess their developmental growth. A child having a low or high weight for height could be due to an imbalance in nutrient intake occurring. It is important to balance dietary intake and physical activity to maintain a healthy weight status. Excessive consumption of food can lead to an overweight/obese weight status which is linked to non-communicable diseases. Parental feeding style can directly impact a child’s set of eating behaviours. Therefore, parents have a strong influence over a child’s growth pattern. In addition, parental awareness of childhood obesity is reported …
A Model For The Spread Of Infectious Diseases In A Region, Elizabeth Hunter, Brian Mac Namee, John D. Kelleher
A Model For The Spread Of Infectious Diseases In A Region, Elizabeth Hunter, Brian Mac Namee, John D. Kelleher
Articles
In understanding the dynamics of the spread of an infectious disease, it is important to understand how a town’s place in a network of towns within a region will impact how the disease spreads to that town and from that town. In this article, we take a model for the spread of an infectious disease in a single town and scale it up to simulate a region containing multiple towns. The model is validated by looking at how adding additional towns and commuters influences the outbreak in a single town. We then look at how the centrality of a town …
Optimisation Of Vitamin D Status For Enhanced Immuno-Protection Against Covid-19, Daniel Mccartney, Declan G. Byrne
Optimisation Of Vitamin D Status For Enhanced Immuno-Protection Against Covid-19, Daniel Mccartney, Declan G. Byrne

Abstract
Background
Vitamin D deficiency (serum 25(OH)D<50nmol/l) is common in Ireland, particularly amongst older adults, hospital inpatients and nursing home residents. Vitamin D deficiency is associated with increased risk of acute viral respiratory infection and community acquired pneumonia, with several molecular mechanisms proposed to explain this association. Vitamin D supplementation has also been shown to reduce the risk of respiratory infection.
Vitamin D and Covid-19
Correction of vitamin D deficiency is thought to suppress CD26, a putative adhesion molecule for Covid-19 host cell invasion. Vitamin D may also attenuate interferon gamma (IFNγ) and interleukin-6 (IL-6) inflammatory responses, both potent predictors of poorer outcome in critically-ill ventilated patients including those with Covid-19.
Vitamin D Requirements
Irish adults require 25-30μg/d of vitamin D3, an intake not achievable by diet alone, to reliably maintain serum 25(OH)D levels >50nmol/l. Supplementation with doses up to 100μg/d has been shown to be safe for adults, and many agencies and expert …

Human Skills Assessment As A Support To Human Factor Management, Lorenzo Comberti, Micaela Demichela, Maria Chiara Leva
Human Skills Assessment As A Support To Human Factor Management, Lorenzo Comberti, Micaela Demichela, Maria Chiara Leva
Conference papers
Automatization, robotics and Industry 4.0 are deeply modifying the working condition with an expected reduction of the number of workers employed in traditional job and an increasing request of new professions. Despite these technologies could limit the involvement of workers, in some sectors humans are still widely employed, as in assembly line of manufacturing companies. As a consequence of this, the Human Factor (HF) will still have relevant influence in term efficiency, quality and safety performances.
This paper approached the HF analysis into the manufacturing field in an assembly line. This study was focused on the analysis of those human-skills …

Approximately 12% of the Canadian population uses private wells for daily water consumption; however, well water testing rates are on the decline, resulting in an increased risk of waterborne acute gastrointestinal illness. To date, limited research has explored the determinants influencing well testing practices. Accordingly, the current study sought to investigate the drivers of “one-off” and repeat well water testing in southern Ontario during the 5-year period 2012–2016, using the worlds largest private groundwater testing data-frame. Data from >400,000 wells were geospatially integrated with all tests conducted by the provincial laboratory in southern Ontario. The Ontario Marginalization Index (ON-Marg) was …

Groundwater contamination constitutes a significant health risk for private well users residing in rural areas. As the responsibility to safeguard rural private domestic groundwater typically rests with non-expert homeowners, interventions promoting risk mitigation and awareness represent the most viable means of preventing supply contamination. However, no global review or pooled analyses of these interventions has been undertaken to date. The current study sought to identify and quantify the performance of private well interventions from 1990 to 2018 via a global systematised review and pooled analysis. The PICO (Population-Intervention-Comparison-Outcome) approach was employed for literature identification. Relevant studies were statistically analysed across …
Covid-19: A Simple Curve Approximation Tool, Jane Courtney
Covid-19: A Simple Curve Approximation Tool, Jane Courtney
Articles
In the current COVID-19 pandemic, much focus is put on ‘flattening the curve’. This ‘curve’ refers to the cases versus time graph, which shows the rise of a disease to its peak before descending. The aim in a pandemic is to flatten this curve by reducing the peak and spreading out the timeline. However, the models used to predict this curve are often not clearly outlined, no model parameters are given, and models are not tested against real data. This lack of detail makes it difficult to recreate the curve from these models. What is much needed is a simple …

Objective To assess the cost-effectiveness of a mobile health-supported lifestyle intervention compared with usual care.
Methods We conducted a cost-effectiveness analysis from the perspective of the publicly-funded health care system. We estimated costs associated with the intervention and health care utilisation from first antenatal care appointment through delivery. We used bootstrap methods to quantify the uncertainty around cost‐effectiveness estimates. Health outcomes assessed in this analysis were gestational weight gain (GWG; kg), incidence of excessive GWG, quality-adjusted life years (QALYs), and incidence of large-for-gestational-age (LGA). Incremental cost-effectiveness ratios (ICERs) were calculated as cost per QALY gained, cost per kg of GWG …

The Development And Trial Of Systematic Visual Search: A Visual Inspection Method Designed To Improve Current Workplace Risk Assessment Practice, Victor Hrymak, Jan Devries
Reports
Visual inspection is a core element in hazard identification. However, poorly conducted visual inspections are problematical for workplace inspection practice as observable hazards that should be seen, are often missed. To address this problem, a novel method; systematic visual search, was developed and tested under randomised controlled trial conditions using commercial kitchens as workplaces. A total of 211 participants were recruited and in the control condition, N = 104 conducted their visual inspection as normal. In the experimental condition, N = 107 received training in the use of systematic visual search. Control group participants were only able to identify a …

Conference papers
New assisted driving technology provides a solution to enabling driver persistence while also addressing older adult fitness to drive issues. The proposed driver assistance system follows a detailed literature review, an analysis of secondary data, and the specification of a solution using human machine interaction (HMI) design methods. Overall, the assisted driving concept follows from a principled/ethical perspective in relation to promoting self-efficacy and enablement for older adults. The system is conceptualized as a supportive friend or ‘co-pilot’. It is argued that the use of new car-based sensors, along with machine learning intelligence and novel multimodal HMI communication methods will …
