ABSTRACT

Many steam turbine modernizations projects evaluated today are viewed by operators with focus to mitigate risk, minimize outage time, and maintain reliability, while getting the best cost-benefit possible. This technical paper will take you through the steps on how the owner/operator, Gainesville Regional Utilities (GRU), began evaluating traditional modernization approaches for their JR Kelly Unit 8, reevaluating alternatives from multiple suppliers, and eventually selecting a Brownfield Steam Turbine Generator Exchange (BEX) as the most technically viable and economic solution to support their current and future power plant needs. Utilizing a brownfield exchange concept, known most typically to be associated with gas turbines, this approach involved removal of the entire original steam turbine-generator unit and replacement with new latest technology steam turbine-generator components, while re-using the turbine building, condenser cooling, and electrical connections. Siemens Energy Inc. (Siemens Energy) provided this Florida utility with a comprehensive package which included demolition of the existing turbine-generator equipment, integration engineering services, supply and delivery of a new steam turbine-generator set, gear box, field installation components, technical field assistance services, field installation services, start up and commissioning services, and performance testing services. Major components were skid mounted and installed onto existing turbine deck. The project was implemented in Spring 2021 during the height of the Covid pandemic, which presented additional challenges to the stakeholders and will be discussed. Authors include GRU Project Manager, GRU Manager of Outage Planning & Major Maintenance, and Siemens Energy Steam Turbine Modernization Project Lead, who will share their critical perspectives of the project.

ABSTRACT

It has been shown that the presence of a hand holding a wireless handset (cell phone) can influence antenna efficiency and the measurement of specific absorption rate (SAR) and electromagnetic compatibility. Head phantoms, used in handset compliance testing to estimate SAR in the head, have achieved low cost and multi-frequency use. Head phantoms typically consist of a thin plastic shell, open on the top, holding a tissue simulating fluid. The specific simulant fluid used is determined by the radio frequency of the test. IEC 62209-1 has recipes, using safe nontoxic materials, for all the required frequency bands. Thus, head phantoms can be reused at different frequencies simply by changing the tissue simulating fluid. However, standards have not adopted the use of hand phantoms because SAR limits in limbs are less restrictive than the head, the tissue depth in a hand is insufficient to make accurate measurements with current electric field probes, and the cost of a solid hand phantom is limited to a single frequency band. Our goal was to determine whether 3D printing techniques would allow the construction of a hand phantom with the same utility as existing head phantoms. We developed this phantom based on computer simulations to determine how much human anatomy needed to be included in the phantom to obtain results consistent with actual use. Electric field scans of a handset alone, and held by the hand phantom, were performed. Comparison of handset scans using the phantom and human subjects was planned, but not performed due to Covid-19 restrictions and subsequent changes in priorities. We feel a fluid-filled 3D printed hand phantom is viable and practical. The 3D print files are available on GitHub. © 2012 IEEE.

ABSTRACT

Aviation is a significant field, especially in Hong Kong with Hong Kong International Airport (HKIA) being one of the largest global transportation hubs. However, in the past years, the COVID-19 pandemic struck and significantly influenced the entire industry. As a result, the HKIA put forth an automation program with an emphasis on safety and efficiency. This paper, therefore, explores the specific process of boarding within the air traveling process due to its high susceptibility to health safety risks, utilizing the methodology of building an agent-based mathematical model and running computer simulations to find the optimal boarding strategy to be applied by Low-Cost Carriers in HKIA under the New Normal to practically achieve efficiency and safety. Throughout modeling, factors such as luggage and carry-ons, walking, seat interference, and disobedience are considered. The proportion of carry-ons stowed and luggage is also considered in further sensitivity analyses. The model is also applicable in the reverse process of disembarking a plane and under special circumstances of COVID-19 capacity limitations. The optimal method of boarding was to be found as the Maximized Corridor Usage (MCU) method. However, the practicality of a boarding method is also a large concern. Hence, the paper also incorporated a practicality factor, considering the simplicity and organization of various boarding methods, and finally concluding the MCU+2 method which boards the passengers in the window and middle seats before aisle seats as the most practically efficient and safe boarding method. © 2022 IEEE.

ABSTRACT

INTRODUCTION: The criteria for the COVID-19 patients' selection that benefit most from ECMO therapy are yet to be defined. In this study, we evaluate the predictive performance of the ECMO mortality predictive models in patients with COVID-19. METHOD(S): A retrospective study was performed in two high-complexity hospitals between March 18, 2020, and December 31, 2021. We included patients over 18 years old with COVID-19 infection confirmed by reverse transcriptase polymerase chain reaction (RT-PCR) who received V-V ECMO due to COVID-19-related ARDS. We evaluated the predictive performance (discrimination, calibration, and accuracy) of death prediction of the following predictive models: i) Prediction of Death due to Severe ARDS in V-V ECMO score (PRESERVE);ii) The Respiratory Extracorporeal Membrane Oxygenation Survival Score (RESP) score;iii) Prediction of Survival on ECMO Therapy- Score (PRESET) score, to predict death. Also, we perform a cost-benefit analysis using the health-related quality of life reported by the CESAR TRIAL and the US life expectancy. Besides, we add the mortality predicted probability calculated with the best predictive model to the cost-benefit analysis. Therefore, the cost/QALY formula was: cost/QALY = cost / age-specific life expectancy*health utilitiesz.ast;survival probability. RESULT(S): We included 38 adult patients who received ECMO due to COVID-19. The PRESET score had the highest discrimination (AUROCs 0.81 [CI95% 0.67-0.94]) and the best calibration (Hosmer-Lemeshow test, p=0.6). The optimal threshold for this score was 7 (sensitivity 67%, specificity 89%, accuracy 78%). The cost per QALY in the USA, adjusted to life expectancy, was higher than UDS 100,000 in patients older than 45 years with a PRESET>10. CONCLUSION(S): The PRESET score had the highest predictive performance and could help in the patient's selection that benefits most from this resource-demanding and highly invasive therapy. Also, the addition of the costbenefit analysis output can help decide which patient to place on ECMO therapy, especially in low-resource settings.

ABSTRACT

Mental illnesses are a serious concern in India where every seventh person suffers from mental health problems-with women more affected than men. While the burden of perinatal mental illnesses grows, India lacks exclusive policies to address it. The COVID-19 pandemic has had an impact on routine antenatal care and institutional deliveries and has also affected the mental health of pregnant women and mothers. We evaluated existing policies. Policy options were evaluated against criteria like cost-benefit analysis, administrative feasibility, human resources, and equity along with the intended and unintended consequences. We propose three policy options: (1) strengthening and focused implementation of the existing national mental health program (NMHP), (2) integrating mental health in the ongoing Reproductive, Maternal, Newborn, Child and Adolescent Health Program, and (3) including a 'maternal' component in NMHP. We offered policy recommendations to fill the gap in addressing the maternal mental health challenge in India. Copyright © 2022. The Author(s).

ABSTRACT

AIM: To explore international experiences of using blended learning in preparing nursing and midwifery students for initial professional registration to inform future education policy. BACKGROUND: The global nursing and midwifery skills shortage and need for an expanded nursing workforce that is fit for contemporary care delivery is widely acknowledged. The immense pressure the profession was already under because of austerity, staff shortages and increasingly complex healthcare needs has been worsened by the Covid-19 pandemic. The UK is extending and evaluating the use of blended learning programmes for pre-registration nursing and midwifery students to help address these issues. This study sought to explore relevant nursing and midwifery experiences from outside the UK to help inform future health professional education policy here and elsewhere. DESIGN: Cross-sectional, sequential, mixed methods study PARTICIPANTS/SETTINGS: Nursing/nurse education leaders from across International Council of Nurses regions METHODS: Exploratory online survey (n = 32) and three follow-up case studies (March-May 2021). Participants' knowledge and experiences of blended learning were examined along with any perceived benefits for workforce development and successful strategies for addressing the challenges blended learning presents in this context. Case studies were developed inductively from survey responses and follow up telephone calls to provide more detailed information about reported successes. RESULT(S): Participants reported flexibility, cost effectiveness, increased student/tutor and student/student communication and interaction as benefits of blended learning. Challenges included the design and use of interactive learning resources, appropriate preparation and support for staff and students, the potential of blended learning to exacerbate otherwise hidden disadvantage and the need for multi-stakeholder cost/benefit evaluation. CONCLUSION(S): Blended learning is used globally in the pre-registration education of nurses, midwives and other healthcare professionals. These results broadly mirror the literature regarding the benefits blended learning offers healthcare students, staff and organisations and the strategies employed to mitigate risk. As the deployment of blended learning nursing and midwifery programmes expands, further work is needed to address gaps in the current evidence base regarding the practice and impact of this approach. These concern adequate preparation and support of students and staff, ensuring access to appropriate equipment and connectivity, exploration of student perceptions that online learning is of lesser value and comprehensive multi-stakeholder, exploratory evaluation to uncover any hidden factors and impact. TWEETABLE : Blended learning plays an effective part in the education of pre-registration nursing and midwifery students to help tackle global workforce shortages, but further work is needed to address gaps in the current evidence base regarding the practice and impact of this approach.

ABSTRACT

Introduction: As of April 2022, the COVID19 global pandemic has resulted in over six million deaths globally, and over 81 million cases of COVID19 in the United States. Objective(s): The objective of the presentation is to share estimated direct and indirect costs due to COVID19 infection juxtaposed with the costs of COVID19 vaccine administration in the United States. Method(s): A literature review was conducted to identify potential cost savings from being immunized against COVID19. The costs of COVID19 vaccinations, direct costs related to healthcare and types of indirect costs were noted. Result(s): After reviewing over 40 resources, several costs were identified. The cost of COVID19 vaccine series, as defined by the Centers of Medicare and Medicaid Services (CMS), is currently USD40 for single-dose and USD40 per dose in a multiple-dose series. It is estimated that the average hospitalisation stay of an uninsured inpatient was ~USD7000-USD10,000 per day. The average cost of 12 major metropolitan cities in the United States were estimated for primary care facilities, urgent care facilities, and emergency room visits at USD195, USD239, USD1,425, respectively. As of April 2, 2022, 77% of the US have received at least one dose of COVID19 vaccine and 66% are considered to be fully vaccinated against COVID19 primary series. Conclusion(s): According to the data, the cost reduction in healthcare is consequential and cost-effective in vaccinating the population. This analysis contributes to the limited reports of a national cost-benefit analysis.

ABSTRACT

In mitigating the peak demand, the energy authority in Malaysia has introduced the enhanced time of use (EToU). However, the number of participants joining the programs is less than expected. Due to that reason, this study investigated the investment benefit in terms of electricity cost reduction when consumers subscribe to the EToU tariff scheme. The significant consumers from industrial tariff types have been focused on where the load profiles were collected from the incoming providers' power stations. Meanwhile, ant colony optimization (ACO) and particle swarm optimization (PSO) are applied to optimize the load profiles reflecting EToU tariff prices. The proposed method had shown a reduction in electricity cost, and the most significant performance has been recorded congruently. For a maximum 30% load adjustment using ACO optimization, the electricity costs have been decreased by 10% (D type of tariff), 16% (E1 type of tariff), 9% (E2 kind of tariff), and 1.13% (E3 type of tariff) when compared to the existing conventional tariff. The cost-benefit of the EToU tariff switching has been identified where the simple payback period (SPP) is below one year for all the industrial types of consumers.

ABSTRACT

It has been more than two years since the world faced a global pandemic of COVID-19, which affected the global economy negatively and took many human lives. This paper considers the extended susceptible-exposed-infectious-recovered (SEIR) model and finds out whether it is effective for the government of Kazakhstan to conduct massive free PCR testing of the exposed population. To this end, we constructed a new mathematical model and the government cost function that incorporates the hospital cost for the COVID-19 treatment and the cost of PCR testing. To address the above-mentioned objectives, we constructed nonlinear differential equations for our epidemic model and numerically solved them. Furthermore, the government's cost was modeled as a function that depends on the rate of PCR tests. The findings of the numerical analysis show that the government's cost is minimized if the exposed individuals were tested for the disease as often as possible. Moreover, testing both susceptible and exposed individuals is not beneficial in terms of the economic cost. © 2022 IEEE.

ABSTRACT

This study aims to uncover some key elements of successful home-learning of mathematics, based on students’ perceptions, during the COVID-19 pandemic and offer recommendations for mathematics learning beyond the crisis. Throughout our work, we aimed to examine students’ reflections on mathematics learning and learning environments that assisted their ease of transition from in-school face-to-face learning to home-schooling during the COVID-19 isolation. In this paper, we will present how mathematics learning has changed for upper secondary school students in Austria and outline students’ perspectives in relation to their new learning experiences during the period of school closures. Through the use of case study principles enhanced by some design-based research approaches, we were able to illustrate that (a) familiarity with the context, (b) problems or tasks as learning triggers, (c) mathematics learning as a social as well as individual process, and (d) perceived positive cost-benefit analysis of learning mathematics are key to students’ learning success. Although these categories were key for the students when learning mathematics in home-schooling during the current crisis, these categories could be equally considered when education moves back to school or in mixed learning environments post COVID-19.

ABSTRACT

The intermediate respiratory care units (UCRI) are areas of monitoring and specialized care of patients with acute or chronic-exacerbated respiratory failure, whose severity does not require admission to an intensive care unit, but which due to their complexity cannot be treated in conventional hospitalization. Although the COVID-19 pandemic has proven its usefulness in the management of critical respiratory patients, the historical trajectory of the UCRI comes from many years ago, in which its cost-effectiveness has been demonstrated by far. This document presents a series of questions and answers on the history of the UCRI, in addition to the criteria for admission, infrastructure, human and technical resources, and the types of existing Units. Within the UCRI year 2021-2022 designated by the Spanish Society of Pneumology and Thoracic Surgery, any scientific dissemination linked to the in-depth knowledge of these units is timely, where multidisciplinarity and the work of professionals related to the care of critical respiratory patients converge.

ABSTRACT

Introduction &Objective: Acute renal colic due to obstructing stones has been a challenge for urologists to manage during the COVID-19 pandemic. Due to overwhelmed hospital resources, operating room (OR) time and staff became scarce, resulting in prolonged pain and suffering for patients. Early during the pandemic, we instituted an office-based ureteral stent placement protocol to relieve immediate discomfort. Later with less constrained OR availability, we extended this protocol to patients undergoing chronic stent changes. Method(s): Patients who presented with severe renal colic due to obstructing stones were offered immediate office-based ureteral stent placement under minimal sedation. Patients filled a prescription of diazepam 10mg and were brought to the procedure suite 2 hours later. Intramuscular ketorolac 15mg was given and 2% lidocaine lubricant jelly was inserted per urethra. Flexible cystoscopy was performed with a standard 16Fr scope, and the stent was placed through the cystoscope. For the first two cases, a 0.038" hybrid wire and 4.8fr stent were used while subsequently, a 0.035" stiff hydrophilic nitinol wire and 4.5fr stent were used. No intraoperative fluoroscopy was used. After stent placement, KUB X-Ray was done to confirm stent placement. Result(s): Seven patients (4 females, 3 males) with a mean age of 62.5 years and a mean BMI of 31.3 underwent an office-based procedure. Five stent insertions were done for obstructing ureteral stone (unilateral = 4, Bilateral = 1) and 2 stent changes for ureteral stricture and ureteral obstruction due to fibroids. In most cases, it was clear when the wire had gone past the stone, as there was immediate efflux of urine into the bladder. The efficiency of the procedure was greatly increased by changing the wire and stent size. Stent placement failed in one case due to overfilling of the bladder causing acute angulation of the ureteral orifice. The stent was later inserted under general anesthesia. Conclusion(s): Office-based ureteral stent insertion and exchange are safe and effective even in the absence of fluoroscopy. Further studies are needed to investigate predictors of success of office-based stent insertion, along with cost analysis to expand its use routinely.

ABSTRACT

The COVID-19 pandemic posed challenges to governments in terms of contact tracing. Like many other countries, Germany introduced a mobile-phone-based digital contact tracing solution ("Corona Warn App"; CWA) in June 2020. At the time of its release, however, it was hard to assess how effective such a solution would be, and a political and societal debate arose regarding its efficiency, also in light of its high costs. This study aimed to analyze the effectiveness of the CWA, considering prevented infections, hospitalizations, intensive care treatments, and deaths. In addition, its efficiency was to be assessed from a monetary point of view, and factors with a significant influence on the effectiveness and efficiency of the CWA were to be determined. Mathematical and statistical modeling was used to calculate infection cases prevented by the CWA, along with the numbers of prevented complications (hospitalizations, intensive care treatments, deaths) using publicly available CWA download numbers and incidences over time. The monetized benefits of these prevented cases were quantified and offset against the costs incurred. Sensitivity analysis was used to identify factors critically influencing these parameters. Between June 2020 and April 2022, the CWA prevented 1.41 million infections, 17,200 hospitalizations, 4600 intensive care treatments, and 7200 deaths. After offsetting costs and benefits, the CWA had a net present value of EUR 765 m in April 2022. Both the effectiveness and efficiency of the CWA are decisively and disproportionately positively influenced by the highest possible adoption rate among the population and a high rate of positive infection test results shared via the CWA.

ABSTRACT

Resumen Las Unidades de Cuidados Respiratorios Intermedios (UCRI) son áreas de monitorización y atención especializada de pacientes con insuficiencia respiratoria aguda o crónica-agudizada, cuya gravedad no precisa de ingreso en una Unidad de Cuidados Intensivos, pero que por su complejidad tampoco pueden ser tratados en planta de hospitalización convencional. Si bien la pandemia por COVID-19 ha demostrado su utilidad en el manejo del paciente respiratorio crítico, la trayectoria histórica de las UCRI viene de muchos años atrás, en la que se ha demostrado su coste-efectividad con creces. El presente documento presenta una serie de preguntas y respuestas sobre la historia de las UCRI, además de los criterios de admisión, infraestructura, recursos humanos y técnicos, y los tipos de Unidades existentes. En el seno del Año UCRI 2021-2022 designado por la Sociedad Española de Neumología y Cirugía Torácica, es oportuna toda divulgación científica vinculada al conocimiento a profundidad de estas Unidades, donde confluyen la multidisciplinariedad y el trabajo de profesionales relacionados con el cuidado del paciente respiratorio crítico.
