The Impact of Emotional Intelligence and Quality of Work- Life on Organizational
Citizenship Behaviour
Authors: Dissanayake D. F. , Wachissara P. , De Silva P. O.
Published: August 2024

Organizational citizenship behaviour as an emerging concept concentrating on
organizational effectiveness and success has gained intense attention from scholars
since the last decade. Organizational citizenship behaviour plays a crucial role in the
service sector, and profoundly in the banking sector. The quality of work-life and
emotional intelligence as the cannons of Organizational citizenship behaviour act as the
most influential factors in organizational effectiveness. However, the extant literature
in this context is fragmented and limited. Therefore, the study overlooks the impact of
emotional intelligence and quality of work-life on organizational citizenship behaviour.
The study evaluated the perceptions of 150 employees who worked in state banks by
employing a quantitative research design. A self-administered 5 point Lickert scale
questionnaire designed to measure the variables. The gathered data were analyzed
incorporating Partial Least Square – structural equation modelling through PLS path
modelling and SPSS. The findings ascertained a significant relationship between the
quality of work-life, emotional intelligence and organizational citizenship behaviour.
Moreover, quality of work-life is determined as the most influential variable in
establishing Organizational citizenship behaviour. Thus, the study recommends a
regulatory and policy framework to encapsulate these elements into Organizational
Citizenship Behaviour.
Development and Flight Demonstration of An Active Seat Mount System for Aircrew Whole-Body Vibration Mitigation on NRC Bell-412 Helicopter
Authors:   National Research Council Canada, Chen Yong , Fereidooni Amin , Wickramasinghe Viresh
Published: August 2024

Helicopter aircrew are exposed to high levels of whole-body vibration (WBV) in fight operations, which may degrade their ride comfort and performance in the short-term, and contribute to some health issues in the long-term. This paper presents the latest development and flight test demonstration results of an active seat mount system that is designed to reduce helicopter aircrew WBV levels through active cancellation of the N/rev vibration peaks related to the helicopter main rotor speed. A prototype airworthy hardware of the active seat mount system has been developed based on previous bench-top-test designs to meet airframe integrity requirements for installation and flight testing on the Bell-412 helicopter. Extensive experimental results on human occupants using a shaker table facility and flight demonstrations on the NRC Bell-412 helicopter in representative flight conditions are presented and discussed. The active seat mount system has achieved significant reduction to the occupant WBV levels at the bottom seat cushion interface per ISO2631/MIL-STD-1472G metrics, and also showed effective mitigation to the occupant head vibrations. These investigations demonstrate that the active seat mount technology is a feasible solution for helicopter aircrew WBV mitigation.

Authors:   HPCMP CREATE™, Abras Jennifer , Hariharan Nathan
Published: August 2024

Mid-fidelity computational techniques have long been sought after in the engineering community to expedite the generation of high-quality engineering data. As digital engineering gains prominence, the demand for faster computational methods continues to grow. Within the rotorcraft community, actuator line and immersed boundary methods play a crucial role as mid-fidelity tools for modeling full helicopters. This study investigates the efficacy of mid-fidelity immersed boundary and actuator line methods using the HPCMP CREATETM-AV Helios ROAM model in predicting the fuselage download of the ROBIN wind tunnel model. Predictions from these methods are compared against both high-fidelity computations and available wind tunnel data. The study also examines the impact of combining mid-fidelity and high-fidelity elements on the results and the time required for solution. The findings indicate that employing mid-fidelity rotor and fuselage models yields sufficiently accurate trends in fuselage download across various advance ratios and thrust levels. Additionally, combining a mid-fidelity rotor with a high-fidelity fuselage offers a favorable balance between download accuracy and simulation efficiency.

Authors:   Leonardo Helicopters, Cerudelli Elena ,   Kopter Group, Spiess Christian , Barber James , Frassoldati Gregorio
Published: August 2024

The present study describes the computational methodology adopted to evaluate the aerodynamic characteristics of a shrouded tail rotor. The dependence of the aerodynamic characteristics of a shrouded rotor on the shroud geometry and flight condition deeply affects the accuracy in estimating the thrust sharing of the antitorque system. Experimental testing and numerical investigations have been carried out in the past to characterize the shrouded tail rotor performance and the influence of the variation of the characteristic geometrical parameters. In this study, a modified Virtual Blade Model (VBM) approach has been exploited to model the structure of the flow field produced by the AW09 shrouded tail rotor operating in hover. The proposed modified VBM was tested on the isolated configuration along with the canonical model implementation. By correlation with experimental and numerical data, the introduced modification translated into modeling improvements both in terms of accuracy and stability. Finally, the modified model has been applied to the shrouded configuration by means of RANS and SBES simulations, and again the results are compared with experimental and numerical data. During the analysis different turbulence models were tested. The performance predictions achieved through Virtual Blade Modeling show a close correlation with the ones obtained by adopting a fully resolved blade approach with a significant saving in computational cost.
A Dual-Step Deep Learning-Based Surrogate Model for Dynamic Stall Predictions
Authors:   HPCMP CREATE, Abras Jennifer , Hariharan Nathan
Published: August 2024

In the field of aerodynamics, there is a growing need for rapid load prediction in engineering applications. Surrogate modeling offers a promising solution, providing faster results compared to high-fidelity computational models. This study focuses on a Machine Learning (ML) framework tailored for surrogate modeling, specifically for integrated aerodynamic load predictions in aircraft design. Central to this framework is a Deep Neural Network (DNN) component capable of handling both steady-state and fluctuating aerodynamics. A key challenge for surrogate models lies in maintaining prediction accuracy, especially in scenarios involving nonlinear flow phenomena like flow separation and transonic shifts. To address these challenges, we introduce a two-step physics-state predictor that integrates an intermediate Convolutional Neural Network (CNN) component. This approach enhances the surrogate model's capability to accurately represent dynamic separated flows and other nonlinear patterns without relying on unrealistic user inputs. Results are presented for NACA0015 dynamic stall predictions for two different physics-state inputs.
Experimental and Computational Investigations of Propeller-Wing Interactions
Authors:   Georgia Institute of Technology, Srivathsan Shreyas , Sridhar Pranav , Smith Marilyn , Rauleder Juergen
Published: August 2024

A joint experimental-computational research campaign is underway to develop physical understanding and a validation-quality database for a model-scale tractor propeller-wing system. Separate load measurements on the wing and propeller accompany wing surface pressure distributions and flow field measurements via stereoscopic particle image velocimetry (SPIV) at discrete wing spanwise locations for a range of static propeller tilt angles. The physical wind tunnel test is modeled using a high-fidelity computational approach (Helios). Computational simulations aid in assessing the influence of the wind tunnel facility effects and test support structure wake interference, as well as in reducing uncertainties in the physical experiments for use in computational validation. The behavior of the induced thrust and lift at a zero-degree wing angle of attack in the axial flow regime (cruise configuration) is correlated with flow field measurements, showing distinct differences between upwash and downwash fields produced by the propeller. Recirculation regions near the wing upper surface are identified for high propeller tilt angles as the propeller wake interacts with the wing boundary layer. Increased propeller tilt angles result in a decreased wing lift and increased propeller thrust in forward flight, resembling a rotor in ground effect. Results indicate ways to improve computational modeling and refine the physical wind tunnel testing. These will be applied to refine the database to further elucidate physical understanding of the propeller-wing interactional aerodynamics.
Numerical Investigation of Turbulence Transition Models for the Prediction of Helicopter Noise Performance in Hover
Authors:   ONERA, Richez François
Published: August 2024

The capabilities of two different laminar-turbulent transition models are evaluated for the prediction of the PSP rotor performance in hover. The first transition model originates on non-local semi-empirical transition criteria that are calculated on the basis of the history of boundary layer quantities along the wall streamlines. The second one is the Langtry-Menter model that consists in two additional transport equations based on a local transition criterion. The same numerical methods and same post-processing are used with the elsA CFD solver in order to have a fair comparison between the models. Both transition modeling technics provide a good agreement with the experimental measurements concerning the transition position on the upper side of the blade. On the lower side, the predictions are less satisfactory. Transition criteria approach gives good trends while Langtry-Menter results seem to be polluted by the tip vortex flow. A grid sensitivity study shows that Langtry-Menter model requires very fine grid in order to predict the expected behavior while transition-criteria approach is less affected by the grid resolution. In terms of rotor performance, both approaches predict the experimental measurements, Langter-Menter tending to slightly overestimate the Figure of Merit where transition criteria approach slightly underestimates its value.

Authors:   Georgia Institute of Technology, Kwon Jeanine , Esmek Ceren , Tauro-Padival Rahul , Prasad J.V.R. , Feigh Karen
Published: August 2024

Army rotorcraft operations demand precision and adaptability to navigate challenging terrain, respond to real-time mission requirements, and ensure time-to-target arrival. Navigating complex terrain, making real-time trajectory adjustments, and ensuring timely arrival at designated objectives while considering other problems are challenging. This paper focuses on the concept of 4D conformal pilot cueing that can facilitate a significant reduction in pilot workload. To enhance the rotorcraft operations with Army scenarios, a visual cueing method based on Tau Theory for obstacle avoidance is proposed so that the pilot can make a coordinated turn away from the obstacle and safely change the helicopter's trajectory to avoid the collision. To demonstrate the visual cueing method, desktop simulations are performed in Matlab/Simulink environment using simulated pilots.

Published: August 2024

There has been an increasing interest among CrossFit® coaches and practitioners in identifying indicators of sport performance. This study aimed to examine the correlation between anthropometric measures, cardiorespiratory capacity, power, local muscle endurance, and total athleticism score, with performance in the CrossFit® Open 2021. Fourteen male volunteers (aged 30.3 ± 5.8 years) participated in the study and underwent a series of tests on separate weeks. These tests included assessments of body fat percentage (subcutaneous adipose thickness measured at seven sites), maximal oxygen consumption (2 km test in rowing ergometer), muscle power (one repetition maximum in power clean), and muscle endurance (Tibana test, which included the conclusion of four distinct rounds of work). These results were used to calculate the total score of athleticism, which was then compared to the participants performance during the CrossFit® Open 2021. The athletes presented an average of body fat (8.6 ± 2.0%), maximal oxygen consumption (53.3 ± 2.4 mL. (kg.min)-1), 2km row time (07:00 ± 00:21 mm:ss), 1-Repetition maximum in power clean (125.2 ± 21.2 kg) and Tibana test performance (281.0 ± 35.9 repetitions). Interestingly, the top five athletes with the highest scores also achieved the highest z-scores in the CrossFit® Open 2021. Conversely, the four athletes with the lowest TSA score had the lowest z-scores in the CrossFit® Open. Moreover, almost perfect correlation (r = 0.91; p<0.01) was found between the total athleticism score and z-scores in the CrossFit® Open 2021. The total score may be a single measure and holistic indication of athleticism level in CrossFit®. Furthermore, coaches can potentially apply this useful tool for monitoring athletic performance and designing training sessions that address specific areas of CrossFit® performance.

Published: August 2024

Pulmonary arterial hypertension (PAH) is characterized by persistently elevated pulmonary artery pressure and vascular resistance. Sympathetic overactivity in hypertension participates in pulmonary vascular remodeling and heart failure. The present study aims to explore the efficacy of highly selective thoracic sympathectomy (HSTS) on lowering pulmonary artery pressure, reversing pulmonary vascular remodeling, and improving right ventricular function in rats. A total of 24 Sprague–Dawley rats were randomly assigned into the control group (n = 8) and experimental group (n = 16). Rats in the control group were intraperitoneally injected with 0.9% normal saline, and those in the experimental group were similarly administered with received monocrotaline (MCT) injections at 60 mg/kg. Two weeks later, rats in the experimental group were further subdivided randomly into the MCT-HSTS group (n = 8) and MCT-sham group (n = 8), and they were surgically treated with HSTS and sham operation, respectively. Two weeks later, significantly lowered mean pulmonary artery pressure (mPAP), pulmonary artery systolic pressure (sPAP), and the ratio of sPAP to femoral artery systolic pressure (sFAP) were detected in the MCT-HSTS group than those of the MCT-sham group. In addition, rats in the MCT-HSTS group presented a significantly lower ratio of vascular wall area to the total vascular area (WT%), right ventricular hypertrophy index, and degrees of right ventricular fibrosis and lung fibrosis in comparison to those of the MCT-sham group. HSTS significantly downregulated protein levels of inflammasomes in pulmonary artery smooth muscle cells (PASMCs). Collectively, HSTS effectively reduces pulmonary artery pressure, pulmonary arteriolar media hypertrophy, and right ventricular hypertrophy in MCT-induced PAH rats. It also exerts an anti-inflammatory effect on PASMCs in PAH rats by suppressing inflammasomes and the subsequent release of inflammatory cytokines.

Authors: Kaveri Arunachalam , Rajendran Velayudham , Jaishree Tukaram Kshirsagar , Malathi Krishnamoorthy , Kavitha Mohanasundaram
Published: August 2024

Aim:

The aim of this clinical trial rheumatoid arthritis–chronic periodontitis (RA-CP) is to assess the effect of non-surgical periodontal therapy in RA patients.

Materials and Methods:

Sixty RA patients taking disease-modifying anti-rheumatoid drugs (DMARD) with CP were selected from the Institute of Rheumatology, Madras Medical College, randomised into the intervention group (IG) and control group (CG). IG received non-surgical periodontal therapy after the screening visit, but CG did not receive treatment until the 3 months study period. Periodontal parameters were recorded at baseline and after 3 months for both groups. Rheumatoid Disease activity (RD activity) was assessed using disease activity score (DAS28), inclusive of tender joints count (TJC), swollen joints count (SJC), visual analog scale (VAS), and erythrocyte sedimentation rate (ESR) for both groups at baseline and after 3 months.

Results:

At the end of 3 months, IG had significant reduction in RA parameters such as tender joints count (0.0005), swollen joints count (0.0005), ESR (0.003), VAS score (0.0005), and DAS28 values (0.0005) compared to CG. Periodontal parameters at the end of 3 months were also significantly reduced in IG than in CG.

Conclusion:

Non-surgical periodontal therapy might have reduced the burden of systemic inflammatory markers, thus reducing severity of RA in IG. Reduction in tenderness and swelling of joints in the upper arm might have enabled the patients in IG to perform better oral hygiene maintenance procedures.

Authors: Ramadoss Barathkumar , Pari Arun , Santhi Sharanya Shre Ezhil , Ravi Sailatha , Ramanan Ezhilarasan
Published: August 2024

Importance:

Ischemic heart disease is the leading cause of death worldwide. In ST-elevation myocardial infarction (STEMI), delaying reperfusion from the onset of chest pain increases the incidence of mortality and morbidity. Prehospital thrombolysis (PHT) has been evaluated in the setting of STEMI. We performed a systematic analysis of studies of PHT in acute STEMI.

Objective:

The objective of this study was to evaluate the all-cause mortality benefit in STEMI with PHT during short-term and long-term follow-up.

Data Sources:

In December 2020, the Cochrane search strategy was used to analyze randomized control trials, nonrandomized control studies, and registry studies in PubMed, EMBASE, Cochrane Library, Google Scholar, ClinicalKey, and Clinical Trial Registries. The search was repeated, and the included studies were updated in June 2023 to include more recent literature. We restricted the analysis to full-text publications in English.

Study Selection:

Studies using any thrombolytic agent in treating acute myocardial infarction in prehospital and inhospital settings with or without percutaneous Coronary intervention (PCI) were included in the analysis. Selection criteria included patient history and symptoms, electrocardiogram findings, and cardiac markers.

Data Extraction:

We used the Cochrane Handbook for Systematic Reviews of Interventions for assessing bias, the PRISMA flow diagram to show the process of inclusion and exclusion of studies, and RevMan software to perform meta-analysis.

Main Outcomes and Measures:

Outcomes include all-cause hospital mortality rate of PHT versus inhospital thrombolysis (IHT), influence of ischemic median time on all-cause mortality with PHT, and effect of PHT before PCI. The measures must have been observed for a follow-up period of up to 35 days, 1-year, and 5-years.

Results:

Data from 63,814 patients from 32 studies were reviewed. Results indicate a reduction in all-cause mortality in patients assigned to PHT (odds ratio [OR] −0.68, P < 0.00001) compared to IHT. There was a significant reduction in mortality when thrombolytics were administered before PCI (OR − 0.78, P = 0.0001). The overall survival was better with an ischemic time of <2 h. Mortality was higher with longer ischemic time (3 h and 6 h). Among patients who presented within 2 h of the onset of chest pain, mortality was lower compared to primary PCI (pPCI).

Conclusion:

PHT offers faster reperfusion and reduces all-cause mortality compared to IHT. A strategy of PHT within the first 2-3 h of ischemic pain followed by PCI (if indicated) could offer better survival than pPCI.

The article deals with some practical issues in modern bilingual lexicography. Its themes include language resources necessary for the work of a modern lexicographer, basic methodology of lexicographic work, computer format of the dictionary and the final result, a dictionary database. Among the language resources, the existing dictionaries are highlighted together with language corpora as indispensable source of language data for modern lexicography. Methodology is presented by using some practical examples from the Slovenian-English language pair. As the standard computer format of modern dictionaries, SGML/XML format is pointed up as the one allowing to control the structure of the dictionary and because of its software independence. The final result of the lexicographer’s work is the computer database in SGML/XML format that contains information of various levels, with the printed dictionary only one of them.

Authors: Amuzie C.I. , Kalu U.K. , Izuka M.O. , Bassi A.P.
Published: August 2024

Background: Cervical cancer is the fourth most common cancer in women, and it is associated with infection by the Human  Papillomavirus (HPV). There are effective interventions for the prevention of cervical cancer. However, the uptake of these interventions  by women in developing countries is poor. This study assessed the knowledge and practices of cervical cancer preventive measures and  uptake of HPV vaccines among women in Abia State.
Method: This was a descriptive cross-sectional study among women in Abia State. Multistage sampling was used to recruit 700 eligible  women and an ODK interviewerbased structured questionnaire was used to collect the information. Descriptive, bivariate, and  multivariate analyses were done using SPSS version 26. The level of significance was set at 5%.
Results: The mean age of the respondents  was 40.3 ± 9.9 years and the proportion of women with good knowledge of HPV infection and vaccine was 22.0% (95% CI:  18.9- 25.1). The uptake of Pap smear and HPV vaccine was 7% and 3%, respectively, while predictors of good knowledge for HPV infection  and vaccine included higher educational status (aOR = 2.53; 95% CI: 1.73–3.71, p = 0.001), being currently married (aOR = 0.32; 95% CI:  0.18–0.54, p= 0.001) and divorced (aOR = 0.25; 95% CI: 0.13–0.49, p=0.001).
Conclusion: Poor knowledge of HPV infection and vaccines,  and poor uptake of Pap smear and HPV vaccine were prevalent among the respondents. We recommend policymakers design health  education programmes to improve knowledge and preventive cervical cancer practices.

Salmonella spp. and Escherichia coli are two of the most prevalent food-poisoning organisms. As part of this investigation, Escherichia  coli and Salmonella spp. were isolated from some fresh milk and fermented milk products in Zaria. This study aimed to investigate the  prevalence and molecular characterisation of Salmonella spp. and Escherichia coli in fresh milk and fermented milk products vended  Sabon-Gari and Zaria Local Government Area, Kaduna State, Nigeria. Four hundred (400) samples were used consisting of one hundred  (100) samples of milk, 100 samples of Kindirimo, 100 samples of Nono, and 100 samples of yoghurt. In addition, a routine microbiological  isolation detected 11% of the samples positive for Escherichia coli and 16% for Salmonella spp. All isolates were biochemically  characterised and identified; however, none of the selected isolates of Escherichia coli or Salmonella spp. possessed the virulence genes  rfbE or invA. Thus, 16S ribotyping was utilised to authenticate the isolates' identities as Escherichia coli strain NCCP 14540, Escherichia coli  strain E57, Salmonella bongori and Salmonella enterica subsp. enterica serovar Typhimurium. However, more molecular research is  required to determine which other Salmonella and Escherichia coli serotypes were present in the study region.

Published: August 2024

This study investigated science teachers’ beliefs and practice of ICT integration in teaching and learning in Zanzibar. Its objectives were: to assess science teachers' beliefs about the role of ICT integration in teaching and learning and to explore how science teachers integrate ICT in classroom teaching. The study involved 60 science teachers purposively selected from 5 public secondary schools in the Town District of Zanzibar. The schools were selected by using convenience sampling procedures. The study employed a mixed-methods approach and a concurrent nested design. Data were collected by using survey questionnaires, interviews and classroom observation. The quantitative data were analysed using the descriptive analysis technique while the qualitative data were analysed thematically. The findings indicated that the science teachers had varied beliefs about ICT integration in teaching and learning. While some had positive beliefs about ICT integration in teaching and learning, others held negative beliefs. The findings also revealed that the teachers’ actual practice of ICT integration in teaching was inefficient. Insufficient skills and knowledge as well as a lack of confidence in ICT integration were identified as significant obstacles to ICT integration, which caused science teachers to inefficiently integrate ICT in teaching. Based on the findings, the study recommends that the Zanzibar Government through the Ministry of Education and Vocational Training, the Zanzibar Institute of Education, and other educational stakeholders, take comprehensive professional development initiatives to raise teachers’ confidence, skills, and knowledge on integration of ICT in teaching and learning. Studies are needed to address the self-efficacy in ICT integration and the challenges faced by science teachers to integrate ICT in teaching and learning context.
Hazard versus Risk in Perceptions of Food Safety: The Case of Titanium Dioxide

Published: August 2024

This study was conducted to explore the contrast between hazard-based and risk-based assessments of food safety through a case study of the food ingredient titanium dioxide. Based on a hazard-based assessment, titanium dioxide has been banned by the European Food Safety Authority. In contrast, the ingredient is allowed within the limits set by the U.S. Food and Drug Administration. We addressed the following question: How do American consumers describe their perception of threat, or lack thereof, posed by titanium dioxide when informed or reminded that the color additive is common in the United States but banned in the European Union? Focus group participants shared their reactions to a brief video reviewing the titanium dioxide issue. These consumers were comfortable with a risk-based assessment, acknowledging that the potential for harm is low. Participants also identified a paradoxical situation in which they were overwhelmed or desensitized by the wealth of information about the many potential hazards they face yet were disappointed by the lack of actionable information available. Based on these findings, practitioners of risk communication in the food industry would likely benefit from transparency by agencies regarding the distinction between hazard and risk when communicating about food safety policies. Dialogue among agencies such as the European Food Safety Authority and the U.S. Food and Drug Administration could help fill the information gap perceived by the study participants.
Extracellular O-linked β-N-acetylglucosamine: Its biology and relationship to human disease
Authors: Ogawa Mitsutaka
Published: August 2024

Laparoscopic surgery is the main treatment method for patients with gastrointestinal malignant tumors. Although laparoscopic surgery is minimally invasive, its tool stimulation and pneumoperitoneum pressure often cause strong stress reactions in patients. On the other hand, gastrointestinal surgery can cause stronger pain in patients, compared to other surgeries. Transversus abdominis plane block (TAPB) can effectively inhibit the transmission of nerve impulses caused by surgical stimulation, alleviate patient pain, and thus alleviate stress reactions. Remazolam is an acting, safe, and effective sedative, which has little effect on hemodynamics and is suitable for most patients. TAPB combined with remazolam can reduce the dosage of total anesthetic drugs, reduce adverse reactions, reduce stress reactions, and facilitate the rapid postoperative recovery of patients.
Genealogy of Early Islamic Traditions: A Study of Hadith on the Honour of Time
Authors: Mina Revi Fauzi Putra
Published: August 2024

This research addresses the genealogy of early Islamic traditions with a focus on the study of hadith traditions which refer to a collection of traditions containing utterances of the prophet Muhammad which, along with accounts of his daily practice (the Sunna), comprise the main source of guidance for Muslims other than the Qur’an, on the notion of time honouring. The background of this research involves an in-depth understanding of the role and authority of the companions of the Prophet in modelling the practice of time honouring. The research questions led to the scholars' understanding of the concept and an in-depth analysis of critical traditions related to the idea of the respecting of time. The research method employed was a qualitative approach, analysing primary sources in the form of verified traditions. The results revealed that respect for time is not just a functional obligation but rather a spiritual dimension inherent in daily worship practices and morality. The conclusion of this study confirms that time honour in the early Islamic tradition is not merely a routine obligation but a call to build a meaningful and moral quality of life, reflect Islamic values in daily life and forge a profound intellectual and spiritual legacy.

Introduction: Although scarce, regional telestroke networks have been developed worlwide in the last few decades. The COVID-19 pandemic put the healthcare system under exceptional pressure. We aimed to assess the impact of the first year of the COVID-19 pandemic on the telestroke network performance in the central region of mainland Portugal.

Methods: Retrospective multicenter cohort study including the eight hospitals of the regional stroke network. The first year of the COVID-19 pandemic (19/03/2020 to 18/03/2021) was compared with the period that preceded it, between 01/01/2018
and 18/03/2020. We analysed the number of telestroke consultations, the number of patients transferred for endovascular treatment, time metrics and functional outcome (measured using the modified Rankin Scale at three months).

Results: The number of consultations per day and patients transferred per day for endovascular therapy increased 8.2% and 12.9% during the COVID-19 period, respectively. The period between symptom onset/last known well (LKW) moment and admission to the primary hospital (LKW – Door 1 interval) increased by 95.8 minutes (159.5 vs 255.3, p<0.01), as well as the period between admission to the primary hospital and the tertiary hospital (Door1 – Door 2 interval): an increase in 18.5 minutes; 205.6 vs 224.1, p=0.04. The Door 2 - groin puncture interval decreased by 6.7 minutes (49.4 vs 42.7, p=0.08) and the Door 2 – reperfusion period decreased by 24.2 minutes (101.9 vs 77.7, p<0.01). The functional outcome of transferred patients was not affected by the pandemic (OR 0.66 [95%CI 0.7-1.3], p=0.79).

Conclusion: This study showed divergent results in different domains of the stroke care chain. Our results support the relevance of well-established telestroke networks in acute stroke care, especially during periods of high pressure on the public health systems.

Nas comunidades das ilhas de Abaetetuba percebe-se uma variedade de saberes culturais, os quais são adquiridos pelos grupos sociais, dentre eles, as pessoas com deficiência. Muitas são as formas de apreensão desses saberes. Buscando compreender essa realidade, este trabalho tem por objetivo analisar e descrever os saberes culturais de jovens e adultos com deficiência de comunidades das ilhas do município de Abaetetuba, visando conhecer e compreender como se dá o processo de aquisição e aprendizagem desses saberes por pessoas que apresentam limitações físicas, auditivas, visuais, sensoriais e psíquicas. Participaram da pesquisa oito jovens e adultos que residem nas comunidades das ilhas e que apresentam deficiência. A pesquisa foi realizada no Polo 09, o qual engloba quatro comunidades (Sapucajuba, Urucuri, Prainha e rio Marinquara) as quais fazem parte da zona rural, do município de Abaetetuba, na Amazônia paraense. Sobre os aspectos metodológicos, este estudo se utilizou das concepções e orientações do Materialismo Histórico Dialético, por meio de um trabalho de campo, adotando a abordagem participante e qualitativa, contemplando as narrativas orais etnográficas. A coleta dos dados se deu por intermédio das entrevistas semiestruturadas sendo que a análise desses dados teve como teórico de base o antropólogo britânico Tim Ingold, autor que vem realizando grandes pesquisas no campo dos estudos antropológicos, bem como Brandão, Oliveira, Freire, Bardin, entre outros. A partir das questões norteadoras que visaram problematizar sobre as práticas de aprendizagem que representam os saberes culturais de jovens e adultos com deficiência, demonstrando como esses saberes são aprendidos por essas pessoas, referendou-se três categorias de análise para embasar os resultados encontrados, sendo elas: “aprendi na prática, só olhando”; “foi ele/ela que me ensinou”; “foi um dom deixado por Deus”. Constatou-se por meio dos resultados obtidos que os jovens e adultos com deficiência são conhecedores de vários saberes. Foram analisados vinte e seis saberes e destes prevaleceram os que auxiliam na vida cotidiana. Sobre as formas de aprendizagem desses saberes analisados pelas categorias de análise, destacou-se a categoria “foi ele/ela que me ensinou”, num percentual de 61% de ocorrência, em seguida “aprendi na prática, só olhando” com 32 %; e “foi um dom deixado por Deus” com 7% de ocorrência. As reflexões acerca dessas problemáticas são de grande relevância e poderão contribuir significativamente para a compreensão de que as pessoas com deficiência das ilhas demonstram que são capazes de aprender qualquer atividade e das mais variadas formas.

Este artigo investigou o papel do Design Instrucional (DI) na integração de tecnologias educacionais para aprimorar os processos de ensino e aprendizagem. O estudo focou na exploração de como o DI pode ser empregado para desenvolver experiências de aprendizagem eficazes e significativas, adaptadas às necessidades dos alunos contemporâneos. A metodologia adotada foi a pesquisa bibliográfica, conforme orientações de Amaral (2007), envolvendo a seleção e análise crítica de literatura relevante, o que permitiu um entendimento profundo das práticas e impactos do DI no ambiente educacional. Diversas fontes foram consultadas, incluindo trabalhos de autores significativos como Filatro (2008), e Castro e Mill (2018), que contribuíram com perspectivas sobre as práticas educacionais e tecnológicas integradas ao DI. O estudo foi estruturado em várias seções, destacando os fundamentos teóricos e práticos do DI, a importância das tecnologias educacionais na criação de ambientes de aprendizagem dinâmicos e acessíveis, e os desafios éticos associados à implementação tecnológica no ensino. Os resultados indicaram que, com uma integração cuidadosa de ferramentas tecnológicas, o DI pode efetivamente melhorar a qualidade da educação, aumentando o engajamento e a motivação dos alunos. Em conclusão, o artigo reforçou a necessidade de continuar explorando e desenvolvendo o DI em conjunto com avanços tecnológicos para atender às demandas educacionais emergentes.

The focus of the study is to analyze “the effect of working capital and liquidity on the Company's profitability”. The research applies causal quantitative as a method which looks at causal relationships or relationships that are influenced and affect. In this study, data from 10 IDX listed companies were analyzed to see how the variables in the study could affect profitability. Samples were taken purposively, i.e. with certain criteria, then analyzed using the “multiple linear regression test”. The hypothesized t-value results were used in observing the impact of each variable individually, and the results showed that only working capital had an effect on profitability, while liquidity did not. However, when tested together through the f-test, both variables collectively affect profitability. It was also found that 66.7% of the change in profitability could be explained by the combination of working capital and liquidity.

The rapid development of today's technology has a big influence on people's lives and in the health sector. The application of this technology plays an important role in today's health sector. Almost all health institutions utilize information systems in their services. A hospital is a health service that requires fast, accurate and reliable service when serving patients. SIMRS is an information system that is applied digitally in the process of providing health services to patients, to obtain accurate data. To make the analysis easier, one of the methods used for analysis is the PIECES framework, where this framework outlines 6 analysis factors consisting of performance, information, economy, control, efficiency and service. Based on the results of SIMRS analysis research in the Outpatient Registration section using the PIECES Method at Panti Waluyo Hospital, it can be concluded that: 1. SIMRS in terms of Information, Economy, Control (Security), Efficiency, The service supports the service and is in accordance with the patient's needs. 2. In terms of performance, it is very supportive of service, but obstacles are still found when SIMRS experiences a server down error, service takes 20 minutes when it should only take less than 5 minutes.
