Institutional amnesia during large crisis: Effects of poor documentation
Authors: Borglund Erik
Published: October 2024

In this “work in progress” research, we attempt to understand and explore the effects of inadequate documentation during crises. We have studied the work of three different organizations during the first six months of the Covid- 19 pandemic and have been able to ascertain that almost no official documents from the organizations' crisis management teams can be found. The consequences of inadequate documentation resulted in challenges when learning from mistakes, difficulties in real-time learning, and a lack of understanding regarding the rationale behind the decisions made. This institutional amnesia is problematic for many reasons and needs to be further studied. The next step in our research will be to study information culture and try to understand the effect of this amnesia on resilience.

Evacuation Social Support Among New Orleans Households: Implications for Evacuation Management Systems
Authors: Grace Rob , Na Hyeong Suk
Published: October 2024

This study reports findings from a survey administered in 2023 to investigate New Orleans households’ social support networks: family and friends who can provide them with accommodations and other assistance during evacuations caused by hurricanes and other hazards. Findings describe the demographics and evacuation destination and accommodation intentions of households with and without social support, as well as the factors these households consider when choosing an evacuation destination. Preliminary findings show that 86% of respondents report at least one relative or friend with whom they can stay during an evacuation. However, the range and size of respondents’ social support networks vary and influences where they will go and stay during an evacuation. In contrast, 14% of respondents lack social support and these respondents are most likely to stay at a hotel or public shelter during an evacuation. Implications for the design of evacuation management systems are discussed, including systems that support the discovery of vulnerable households and coordination with community organizations that provide transportation and temporary housing during evacuations.

Published: October 2024

Digitalisation has a significant impact on most aspects of society. State agencies with safety and security tasks have to develop effective strategies to manage the opportunities and risks associated with technological innova-tions and increased networking. Emerging digital technologies have the potential to affect work practices and thus the organisational culture of such agencies. To examine the extent to which scientific research has addressed the impact of digitalisation on organisational culture so far, a systematic scoping review was conducted. Preliminary results show that the overall research topic is still in an exploratory phase and studies are primarily from the global north. The analyses show that the majority of studies focuses on artefacts around information data leading to respective work practices around data work.

Published: October 2024

This work-in-progress paper presents the preliminary results of an exploratory study on the effectiveness of a simulator training for ad hoc collaboration between sea- and airborne professionals in the field of maritime search and rescue. To enable this training, two different types of simulators were coupled. This coupled simulation environment provided the 49 (preliminary) study participants—seafaring and helicopter professionals—with authentic simulator training conditions. Our training was developed and tested using a two-phase approach. In the first phase, we used qualitative methods to identify requirements and design a training using insights from domain experts. In the second phase—the preliminary results of which are presented here—we tested the impact of the training on the acquisition and transfer of competencies as rated by the participants. To uncover contingencies of these training effects, we explore demographic predictors. We show which set of participants perceived that they benefited most from the training.

Authors: Boersma Kees , Clark Nathan , Larruina Robert , Roeloffs Emmeline
Published: October 2024

Utilizing social media and crowdsourcing (SMCS) in crisis management is crucial for improving communication and citizen engagement. However, practitioners working in crisis management organizations often face challenges when translating the outcomes of scientific research into actionable knowledge. To aid disaster management organizations, a comprehensive set of resources including practical tools, guidelines, and use examples are necessary. This will help response organizations to integrate the different components of SMCS coherently and consistently in their organizations and to promote disaster resilience for different users. An integrative Framework, developed by the authors as part of the EU-funded Horizon 2020 project, LINKS – strengthening links between technologies and society for European disaster resilience, serves such resources. This paper presents how this Framework came into being and describes its main components. It then provides a case study from the Netherlands, focusing on the scenario of industrial, chemical hazards, to illustrate how the Framework was actually used.

Authors: Liu Ting , Ni Xiaoyong , Sun Jiawei , Peng Ziyi
Published: October 2024

Typhoons significantly impact socio-economics, varying in impact due to unique characteristics. However, limited studies explore why similar intensity typhoons affect regions differently. This study compares the emergency response measures of Zhuhai, Guangdong Province, China, in response to typhoon Hato (2017), Mangkhut (2018), and Higos (2020). These three similar typhoons offer an empirical opportunity to assess the effectiveness of emergency management. This research builds a timeline of Zhuhai's emergency response measures to the typhoons, collects Weibo data 72 hours before and after the typhoon landfall, performs keyword frequency analysis on contents and analyzes in detail the content of weibo postings, and changes in sentiment. Results show that timely and systematic emergency response measures may reduce disaster losses, which means emergency management is crucial in mitigating typhoon impacts, offering valuable lessons for other coastal cities.
Cascading Effects of Critical Infrastructures in a Flood Scenario: A Case Study in the City of Cologne
Authors: Schneider Moritz , Priesmeier Peter , Fekete Alexander , Lichte Daniel , Fiedrich Frank
Published: October 2024

Critical infrastructures, which constitute the backbone of our modern society, are increasingly exposed to natural hazards. Loss of performance or failure of a critical infrastructure can lead to cascading effects that affect even more services and citizens. Floods, as one of the most prominent natural hazards, are prone to affect multiple critical infrastructures at once, making it even more difficult to assess combined effects of these (cascading) disruptions. Hospitals are especially vulnerable in a flood scenario, as they are reliant on multiple other infrastructures, such as power and water supply or the road network. In order to prepare for upcoming events, sophisticated analysis tools are required that are capable of modeling the spatial extent of flood induced disruptions and their impact on critical infrastructure services. In this work, we present a proof of concept that focuses on the impact of multiple disruptions on hospitals. We conducted a case study on an extreme flood scenario in the city of Cologne (Germany). Historically, Cologne has proven vulnerable to river-floods, as thousands of people were affected through floods in in 1993 and 1995. The approach is based on a combination of I) a geographic information system, which makes the extent of disruptions spatially explicit and II) a Bayesian network, which is used to assess the impact of one or multiple disruptions on a single hospital. We present a work-in-progress approach in this work. The results generated using this approach enable a first comparative overview of the expected level of services of the examined hospitals.
Towards a Repository for Datasets of Mass Casualty Incidents
Authors: Hager Florentina , Reuter-Oppermann Melanie
Published: October 2024

Many mathematical models and algorithms addressing logistics around mass casualty incidents (MCI) have been proposed in the literature. However, hardly any data sets exist that can be used to analyse, validate, and evaluate approaches and solutions. As MCI are comparably rare, real-world data is scarce and often extremely sensitive, making it difficult for researchers to get access and build test datasets. In this paper, we therefore present the firststeps towards a repository for the exchange of datasets to facilitate validation and comparison. We first provide an overview of potential stakeholders such as working groups, review disaster-related databases and existing repositories for other fields followed by a preliminary taxonomy to identify and structure the relevant entities and their characteristics within models for disaster management.

Authors: Naoum Fatima Ali , Fakhrey Sura Khudhair , Abdulameer Jeehan Amar , Zidan Noor Sabah Abed
Published: October 2024

Electrooculogram (EOG) has been a valuable clinical neurophysiology tool in the past five decades of the twentieth century. It facilitated understanding more about eye movement, which is clinically useful in identifying the neural substrate disrupted due to brain injuries. This is vital since accurate measurement of neural injuries has a direct bearing on a patient’s life. A number of neurological investigations, including neurological assessment and diagnosis, are done based on measuring eye movements. This essay focuses on using EOG technology and its benefits in identifying limitations of using physiological indices in individuals because of measurable ocular pathophysiological parameters. In the current essay, the major objective will be to discuss the EOG features, the EOG record in healthy individuals, and the relationship of EOG recordings to affected individuals following a neurological event. 
The eye-integrated EOG recorded from the front part of the face measures eye position change and shows an exponential decay of voltage due to its design, eye physiology, and the removal of corneal function slowly from the corneal electrode. This makes it the best choice to provide an eye position record with high accuracy that can be made available easily for clinicians. The rapid recordings obtained using transcranial electromagnetic stimulation could demonstrate that EOG has the potential to provide high pre-surgical planning utilities for brain tumor removal. This technology is also best for identifying physiological variability within an individual; the same concept can be extended to study brain injuries that trigger physiological changes in eye muscles. In effect, it potentially becomes a tool for personalized care wherein severity estimation for brain injuries would be based on measuring ocular function rather than the nature of the injury. Given its clinical potential, the present essay will review EOG technologies to assess eye pixel movement, its potential for clinical evaluation, physiological basis, and the research evidence regarding changes in EOG in affected individuals with brain injury. In this essay, the long-lasting and short-lasting EOG changes are presented as case studies of individuals diagnosed with PTA, hence demonstrating its clinical utility.

The role of central antihypertensives in the treatment of various categories of arterial hypertension
Authors: Pandrc Milena , Kostovski Vanja
Published: October 2024

Primary (essential) hypertension includes about 90% of all cases of hypertension, and the treatment is symptomatic. As the response to the need for suppression of sympathetic activity in the regulation of hypertension, central antihypertensives have been developed, through central and peripheral adrenergic and non-adrenergic mechanisms, to affect the reduction of sympathetic nerve activity, inhibition of norepinephrine release, reduction of systemic vascular resistance, peripheral vasodilatation, reduction of heart rate and lowering of blood pressure. Moxonidine has been proven to be effective and safe, whether used as monotherapy or in combination in the treatment of hypertension in which sympathetic hyperactivity predominates, especially in patients with metabolic syndrome, obese patients, patients with prehypertension and stress induced hypertension with catecholamine hyperactivity

Authors: Bosinci Emil , Jakšić Lazar , Petrov Ivana , Simić Dušica
Published: October 2024

Introduction: Ultrasound-guided supraclavicular block with perineural catheter placement has enabled a significant reduction in block-related complications, as well as far better perioperative pain management. Case report: A 9-year-old boy was admitted for a combined forearm/elbow fracture, with a history of laryngitis. As a result, we opted to perform an ultrasound-guided supraclavicular brachial plexus block under procedural sedation, with the placement of a perineural catheter. We used 25 mL of 0,5% Levobupivacaine. Orthopedic repositioning and internal fixation were performed under procedural sedation and the supraclavicular block with monitoring of basic vital parameters. Throughout the procedure, the patient maintained hemodynamic and respiratory stability, and the pain was postoperatively managed with a continuous Levobupivacaine infusion at 0,2-0,5 mg/kg/h. The patient was discharged on the fifth postoperative day. Discussion: Although information is limited regarding peripheral nerve block in the pediatric population their use in adults is well established, as is a higher degree of skill necessary for their administration in children due to clear anatomic nuance. The utilization of peripheral nerve blocks reduces the incidence of postoperative nausea and vomiting, as well as the use of opioid or nonopioid rescue analgesia. Their benefit is additionally underlined by the fact that adequate postoperative analgesia can reduce exaggerated responses to pain later in life. Conclusion: Ultrasound-guided supraclavicular brachial plexus block with placement of a perineural catheter provides safe and effective perioperative analgesia in children with fractures at or below the level of the humerus.

Authors: Xueqian Wu , Hu Chenming , Yunfeng Dong , Zhi Li
Published: October 2024

Affected by uncertainty, there are errors between the digital twin model and the real system, which need to be corrected and the uncertainty of the model quantitatively evaluated as the basis for selecting the model when using it. However, the satellite digital twin model has the characteristics of multi-dynamic, multi-spatial scale, and multi-physical field coupling. The rigidity problem of differential equations and the multi-scale problem of partial differential equations will appear during numerical solution. If many telemetry parameters are corrected at the system level at the same time, the results will not converge. A multi-granularity negotiation correction framework for satellite digital twin models is proposed. The parameters are grouped by analyzing the correlation and frequency domain characteristics of telemetry parameters. Models of different granularities of satellite subsystems and components are established, and multi-granularity digital twin models are constructed on demand. The coupling relationship between different levels of satellite components is studied, and a negotiation correction method is proposed. The framework is verified using real on-orbit telemetry data. The research results show that the negotiation correction method proposed in this paper improves the RMSE accuracy by more than that of the unused one , and the correction results are more systematic and complete.

Authors: Dejun Wang , Kairan Zhang , Peng Xu , Tianbiao Gu , Wenya Yu
Published: October 2024

In order to solve the problem of vehicle speed planning that meets the constraints of safety and efficiency in complex road environments (large curvature and low adhesion), a differential equation planning method based on vehicle dynamics analysis is proposed. First, the structural parameter expression of the limit speed that meets the lateral tire force constraint during steady-state steering is derived. Secondly, the tire force execution space of the front and rear wheels is combined into an FF diagram, and an implicit differential equation that considers load transfer and driving mode factors is obtained. The differential equation is solved to obtain the limit speed along the path, and a limit speed calculation method for discrete path information is given. Finally, a lateral and longitudinal collaborative model predictive controller is designed, and a CarSim and Simulink joint simulation platform is built. Trajectory tracking simulation experiments are carried out on both continuous and discrete information paths with the planned limit speed. The results show that the limit speed planning method proposed in this paper can complete the trajectory tracking task in complex road environments as quickly as possible while controlling the tire force within the range of the stable friction circle.

Authors: Haifeng Liu , Renguang Tao , Jialing Che , Weiwu Yang , Lichen Zhu
Published: October 2024

In order to explore the influence of load and high temperature on the uniaxial compressive properties of desert sand concrete (DSC), the axial compressive strength test of desert sand concrete after different loads and temperatures was carried out, and the stress-strain curve was measured. The influence of load level, temperature grade and cooling method on the mass loss rate, ultrasonic velocity and uniaxial compressive performance of desert sand concrete after high temperature was analyzed. The results show that as the temperature increases, the mass loss rate of desert sand concrete gradually increases, the axial compressive strength gradually decreases, the peak strain increases significantly, the stress-strain curve tends to be flat, and the elastic modulus decreases continuously. The "pseudoplastic platform" near the axial compressive strength of the stress-strain curve of desert sand concrete after high temperature is more obvious. Based on the two-stage constitutive model of concrete, the constitutive model of desert sand concrete considering the influence of temperature and load level is established. The research results can provide technical support for the performance evaluation of desert sand concrete after high temperature.

Healthcare workers (HCWs) are front-line warriors in the battle against the COVID-19 pandemic. Therefore, it is of interest to assess the psychological and physical effects of personal protective equipment (PPE) among HCWs caring for COVID-19 patients. This cross-sectional study utilized a validated, well-structured questionnaire consisting of 24 questions to collect information on the psychological and physical effects experienced by HCWs. The study adhered to relevant EQUATOR guidelines for reporting. The study collected online data from 114 HCWs working in COVID-19 settings while using PPE. Among the respondents, 33% reported anxiety, 23.1% experienced apprehension after donning PPE, and 68.1% felt discomfort. Additionally, 46.2% required up to 12 hours for psychological restoration after a COVID-19 duty shift, 17.6% were worried about the risk of infection, and 28.6% were extremely worried about infecting family members while on duty. The findings highlight significant discomfort, anxiety, and apprehension among HCWs due to prolonged PPE use, reflecting the immense psychological burden of working in high-risk environments during the pandemic. These results emphasize the need for comprehensive support systems and interventions to address the multifaceted needs of HCWs, including psychological support, adequate breaks, and measures to mitigate physical discomfort.

The efficacy of Ozonated oil in treating chronic periodontitis compared to Chlorhexidine gel following Scaling and Root Planing (SRP) is of interest. Fifty-six patients were randomly assigned to two groups: one receiving Ozonated oil post-SRP and the other receiving Chlorhexidine gel. Periodontal indices (Plaque Index, Gingival Index), Periodontal Probing Depth (PPD), and Clinical Attachment Level (CAL) were measured at baseline, one month, and three months. Intragroup comparisons for Plaque and Gingival indices showed statistically significant improvements over time (p < 0.05), but intergroup comparisons did not reveal significant differences. However, both groups demonstrated statistically significant improvements in PPD and CAL at all-time points (p < 0.05). Further research is warranted to explore Ozonated oil's potential as an antimicrobial treatment for chronic periodontitis and other oral microbial infections.
