To investigate the differences between doctor helicopters (DHs) and disaster medical assistance teams (DMATs) based on past examples and the current situation in Shizuoka Prefecture.
Methods
First, we examined cases in Shizuoka Prefecture from 2014 to 2023, where incidents involving five or more injured individuals were simultaneously managed using multiple DHs. Next, we investigated the presence of DMATs in Shizuoka Prefecture and assessed their role in disaster responses within the prefecture.
Results
Since 2014, there have been eight incidents in Shizuoka Prefecture where multiple DHs were deployed to respond to mass casualties. In contrast, Shizuoka DMATs were placed on standby three times during the same period, with one active deployment during a disaster caused by a landslide in Atami. The other two cases were managed solely by DHs and ambulance teams.
Conclusion
Localized disasters in Shizuoka Prefecture have seen the effective use of multiple DHs for timely patient transportation, particularly when suitable weather conditions permit. In contrast, DMATs are primarily deployed for extended medical activities lasting more than one day. This differentiation highlights the importance of choosing the appropriate medical response approach based on the nature and scope of the disaster.
We derive a generalised asymptotic model for the flow of a thin fluid film over an arbitrarily parameterised non-axisymmetric curved substrate surface based on the lubrication approximation. In addition to surface tension, gravity and centrifugal force, our model incorporates the effects of the Coriolis force and disjoining pressure, together with a non-uniform initial condition, which have not been widely considered in existing literature. We use this model to investigate the impact of the Coriolis force and fingering instability on the spreading of a non-axisymmetric spin-coated film at a range of substrate angular velocities, first on a flat substrate, and then on parabolic cylinder- and saddle-shaped curved substrates. We show that, on flat substrates, the Coriolis force has a negligible impact at low angular velocities, and at high angular velocities results in a small deflection of fingers formed at the contact line against the direction of substrate rotation. On curved substrates, we demonstrate that, as the angular velocity is increased, spin-coated films transition from being dominated by gravitational drainage with no fingering to spreading and fingering in the direction with the greatest component of centrifugal force tangent to the substrate surface. For both curved substrates and all angular velocities considered, we show that the film thickness and total wetted substrate area remain similar over time to those on a flat substrate, with the key difference being the shape of the spreading droplet.
This article analyzes the transformation of an image of ritual violence on the Kenyan coast from the sixteenth century to the present. Drawing on a range of sources, it shows how understandings of “mung'aro” — a ritual of senior male initiation among Mijikenda-speaking peoples — changed as it became an object of inquiry for generations of missionaries, explorers, colonial administrators, local intellectuals, and foreign historians and anthropologists. In the mid-twentieth century, mung'aro became a key feature of Mijikenda traditions of origin in Singwaya, but in such a way that it reversed the direction of a specific form of ritual violence described in nineteenth-century traditions. By focusing on the transposition and recombination of ritual motifs across practical and discursive modalities (namely, ritual and narrative), this article offers a new approach to “the limits of invention” regarding traditions of origin.
Overwhelmingly, philosophers tend to work on the assumption that epistemic justification is a normative status that supervenes on the relation between a cognitive subject, some body of evidence, and a particular proposition (or “hypothesis”). This article will explore some motivations for moving in the direction of a rather different view. On this view, we are invited to think of the relevant epistemic norm(s) as applying more widely to the competent exercise of epistemic agency, where it is understood that cognitive subjects are simultaneously engaged in a number of different epistemic pursuits (distinct “lines of inquiry”), each placing irreconcilable demands on our limited cognitive resources. In effect, adopting this view would require shifting our normative epistemic concern away from the question of how a subject stands with respect to the evidence bearing on the hypothesis at stake in any one line of inquiry, and over onto the question of how well they cope with the inherent risks of epistemic resource management across several lines of inquiry. While this conclusion brings to light important connections between practical and epistemic rationality, it does not collapse the distinction between them. It does, however, constitute a step in the direction of a more systematically developed account of “non-ideal epistemology.”
To perform a scoping review identifying the criteria for the deployment of the United States National Guard (USNG) to domestic sudden-onset natural disasters to identify the body of literature on which further research and policy decisions may be based.
Methods
On January 23, 2023 authors performed a search to identify texts relevant to the involvement of the USNG response to sudden-onset domestic natural disasters. English language texts from any year were considered. Independent reviewers screened titles and abstracts, then full-texts, then extracted data from included texts.
Results
From 886 search results, 34 texts were included. Fifteen criteria for USNG deployment were identified. Lack of security, power failure, and logistical coordination were the most common criteria. Hurricanes were the most common disaster type in the included results.
Conclusions
Disaster response coordinators may use these results to develop policies optimizing the use of the USNG in disaster response.
The flexible flat cable (FFC) assembly task is a prime challenge in electronic manufacturing. Its characteristics of being prone to deformation under external force, tiny assembly tolerance, and fragility impede the application of robotic assembly in this field. To achieve reliable and stable robotic automation assembly of FFC, an efficient assembly skill acquisition strategy is presented by combining a parallel robot skill learning algorithm with adaptive impedance control. The parallel robot skill learning algorithm is proposed to enhance the efficiency of FFC assembly skill acquisition, which reduces the risk of damaging FFC and tackles the uncertain influence resulting from deformation during the assembly process. Moreover, FFC assembly is also a complex contact-rich manipulation task. An adaptive impedance controller is designed to implement force tracking during the assembly process without precise environment information, and the stability is also analyzed based on the Lyapunov function. Experiments of FFC assembly are conducted to illustrate the efficiency of the proposed method. The experimental results demonstrate that the proposed method is robust and efficient.
Asymmetric warfare, conflict and terrorist attacks involving children raise concerns regarding the preparedness to respond to mass casualty incidents involving pediatric patients. The objective of this project was to assess the resources available in the metropolitan Milan area to develop a priority dispatch plan for a mass casualty incident with pediatric patients.
Methods
A focused search of the medical literature and clinical guidelines established a minimal standard requirements of care of pediatric patients involved in an MCI to determine the surge capabilities in terms of number of patients and severity of injuries for each study hospital in the metropolitan Milan area.
Results
The hospitals that took part in the study were either adult trauma centers or pediatric hospitals in the metropolitan Milan area. The overall surge capability identified was of 40-44 pediatric patients involved in an MCI involving pediatric patients, distributed based on age and severity and based on the hospital resources and expertise.
Conclusions
The findings from the metropolitan Milan area shows the basis for non-Pediatric Trauma Center adult and pediatric hospitals to work in synergy to develop MCI response plans involving pediatric patients. Simulations exercises will need to be carried out to evaluate and validate the plans.
During excavations of a Roman villa at Fordham, Essex, a remarkable series of decorated bone and antler veneer plaques were recovered from villa destruction deposits. They are datable to the later fourth or fifth centuries a.d. and probably once adorned a casket holding bathing equipment and jewellery. Spread through the three main rooms of the villa, fragments were recovered from at least 10 metres apart, so the object is likely already to have been broken when deposited. The plaques are decorated with ‘late antique’ style figural, zoomorphic, vegetal and architectural motifs on a cross-hatched background, with the best-preserved design probably relating to female bathing.
Despite the global expansion of electronic medical record (EMR) systems and their increased integration with artificial intelligence (AI), their utilization in disaster settings remains limited, and few studies have evaluated their implementation. We aimed to evaluate Fast Electronic Medical Record (fEMR), a novel, mobile EMR designed for resource-limited settings, based on user feedback.
Methods
We examined usage data through October 2022 to categorize the nature of its use for disaster response and determine the number of patients served. We conducted interviews with stakeholders and gathered input from clinicians who had experience using fEMR.
Results
Over eight years, fEMR was employed 60 times in 11 countries across four continents by 14 organizations (universities, non-profits, and disaster response teams). This involved 37,500+ patient encounters in diverse settings including migrant camps at the US-Mexico and Poland-Ukraine borders, mobile health clinics in Kenya and Guatemala, and post-earthquake relief in Haiti. User feedback highlighted adaptability, but suggested hardware and workflow improvements.
Conclusion
EMR systems have the potential to enhance healthcare delivery in humanitarian responses, offer valuable data for planning and preparedness, and support measurement of effectiveness. As a simple, versatile EMR system, fEMR has been deployed to numerous disaster response and low-income settings.
Caregivers are responsible for the in-home care of children with chronic medical conditions (CMCs) and may have care-related questions in order to support the child’s higher quality of life. We propose using a digital health platform, the personal health library (PHL), facilitating collection, organization, utilization, storage, and retrieval of health information, that will allow us to develop an mHealth smartphone app to facilitate patient/caregiver engagement and self-care management of children with CMCs.
Methods
Pilot Application of the PHL in the Pediatric Chronic Medical Conditions Population: We will design the PHL to collect and integrate data from health and non-health information, in various formats and modalities, including 1) Parent/caregiver-reported data; 2) Clinical data and; 3) Social determinants of health (SDoH) data; 4) Observations of Daily Living (ODL) data including the PedsQL Parent Questionnaire and the Functional Status Scale. The app will be customized to provide information regarding training in post-acute hospitalization care and deliver information on troubleshooting medical technology care, i.e. tracheostomy care.
Conclusion
We expect that the design of the PHL application will ultimately provide a layer of support for parents and caregivers of children with CMCs for whom home health is not available following hospitalization.
Humanitarian crises often require urgent medical care to people of concern. Such medical aid includes assessing and treating acute medical needs and ongoing chronic health conditions. Among the people of concern there are children, who are often the most vulnerable population in humanitarian contexts because they often lack the experience, independence, and cognitive and verbal skills to deal with the ordeals they are facing. These limitations might prevent identification and diagnosis of pain. The under-diagnosis and under-treated pain by health care providers might be also due to the perceived urgency of more acute or life-threatening medical needs with limited medical equipment and personnel, lack of awareness, or assessment tools in such contexts. Additionally, due to issues of anonymity and lack of formal guidelines, there is a severe lack of standardized registration of children’s pain conditions in humanitarian crises. Finally, acute pain is also a predictor of post-traumatic stress disorder, a common outcome in such disasters. We call on health care providers to use standardized scales to assess children’s pain intensity, frequency, and duration, and to treat it appropriately. These will not only reduce children’s physical suffering but may also prevent subsequent risk of PTSD.
Hemorrhage control, triage efficiency, and triage accuracy are essential skills for optimal outcomes in mass casualty incidents. This study evaluated user application of skills through a Virtual Reality (VR) simulation of a subway bombing.
Methods
EMS clinicians and healthcare professionals engaged in a VR simulation of a bomb/blast scenario utilizing VRFirstResponder, a high-fidelity, fully immersive, automated, customizable, and programmable VR simulation platform. Metrics including time to control life-threatening hemorrhage and triage efficacy were analyzed using median and interquartile ranges (IQR).
Results
389 EMS responders engaged in this high-fidelity VR simulation encountering 11 virtual patients with varying injury severity. The median time to triage the scene was 7:38 minutes (SD = 2:27, IQR = 6:13, 8:59). A robust 93% of participants successfully implemented all required hemorrhage control, with a median time of 3:51 minutes for life-threatening hemorrhage control (SD = 1:44, IQR = 2:41, 4:52). Hemorrhage control per patient took a median of 11 seconds (SD = 0:47, IQR = 0:06, 0:20). Participants accurately tagged 73% of patients and 17% effectively utilized the SALT sort commands for optimal patient evaluation.
Conclusion
The VRFirstResponder simulation, currently under validation, aims to enhance realism by incorporating distractors and refining assessment tools.
Recent studies of viscous dissipation mechanisms in impacting droplets have revealed distinct behaviours between the macroscale and nanoscale. However, the transition of these mechanisms from the macroscale to the nanoscale remains unexplored due to limited research at the microscale. This work addresses the gap using the many-body dissipative particle dynamics (MDPD) method. While the MDPD method omits specific atomic details, it retains crucial mesoscopic effects, making it suitable for investigating the impact dynamics at the microscale. Through the analysis of velocity contours within impacting droplets, the research identifies three primary contributors to viscous dissipation during spreading: boundary-layer viscous dissipation from shear flow; rim geometric head loss; and bulk viscous dissipation caused by droplet deformation. This prompts a re-evaluation of viscous dissipation mechanisms at both the macroscale and nanoscale. It reveals that the same three kinds of dissipation are present across all scales, differing only in their relative intensities at each scale. A model of the maximum spreading factor (βmax) incorporating all forms of viscous dissipation without adjustable parameters is developed to substantiate this insight. This model is validated against three distinct datasets representing the macroscale, microscale and nanoscale, encompassing a broad spectrum of Weber numbers, Ohnesorge numbers and contact angles. The satisfactory agreement between the model predictions and the data signifies a breakthrough in establishing a universal βmax model applicable across all scales. This model demonstrates the consistent nature of viscous dissipation mechanisms across different scales and underscores the importance of integrating microscale behaviours to understand macroscale and nanoscale phenomena.
The objective of this study was to determine what factors are associated with behavioral health in veterinary disaster responders.
Methods
An online cross-sectional survey was distributed via snowball sampling. Results were analyzed using chi-square analyses.
Results
Responses from 237 veterinarians were analyzed. Being involved in more than 1 disaster event was associated with higher anxiety and/or depression (43.4% vs 28.6%, respectively), difficulty with relationships (28.1% vs 14.3%, respectively), and a greater prevalence of sleep problems (44.6% vs 28.0%, respectively) compared to only being involved in 1 event. Veterinarians that were deployed longer than 2 months had the highest prevalence of anxiety and/or depression (43.9%) and sleep problems (50.0%). Veterinarians that received behavioral health training before deployment had lower rates of anxiety and/or depression (27.8% vs 42.9%, respectively) compared to those who did not receive training. Respondents involved with depopulation had the highest rates of anxiety and/or depression (66.7%) and sleep problems (58.1%).
Conclusions
Factors associated with behavioral health outcomes included the number and length of deployments, receiving behavioral health training, and being involved in depopulation. To reduce the risk of behavioral health outcomes, interventions such as time-off and behavioral health support are needed.
