Interactivity that matters
Authors: Tronstad Ragnhild
Published: October 2022

Skilfully applied, interactivity is an ingredient that may boost engagement and enhance the performance experience of a young audience. However, it can also lead to confusion, banalization and even embarrassment. What are the parameters for interactivity to be experienced as meaningful, and when is it unproductive?

In this article I shall address how conceptions of artistic quality is challenged by contemporary practices of interactivity and audience participation in theatre for young audiences. The question will be discussed in relation to three performing arts productions presented in The Cultural Schoolbag (TCS): One participatory theatre performance and two interactive digital productions. The latter two were developed as part of Kulturtanken – Arts for Young Audiences Norway’s 3-year development project in digital mediation, FoNT (Formidling og Ny Teknologi/Mediation and New Technology). Equipped with theories of games and play, I shall discuss how the three projects succeed in presenting the kids with opportunities for meaningful interaction. I conclude by pointing out some of the parameters that are vital in order to provide meaningful interaction in performing arts aimed at a young audience – interactions that matter.

Authors:   The Korean Society of Special Education, Kim Dongil , Cho Younghee , Kim Myeongnan
Published: October 2022

This study analyzes the eye tracking characteristics associated with the reading ability of elementary school students with learning difficulties by using the LPA(latent profile analysis). A total of 32 elementary school students in S city were classified based on the results of the reading test. Eye tracking characteristics of each latent group were compared and analyzed by measuring the movement of the gaze in the reading fluency and silent word reading test. As a result, LPA identified five subgroups with patterns of strengths and weakness in the reading tests. There was a significant difference in the reading test scores for each latent group. Regarding the eye tracking variables for the latent groups, there was a statistically significant difference between the groups in both the total fixation time and regression in the reading fluency test. In addition, it was confirmed that the number of fixed gazes, the number of regressions, and the number of saccades were significant variables in the classification of the latent group. Based on these results, Implications of these results and suggestions for follow-up studies were discussed.
AGARRAR O DIA: CORPO, HISTÓRIA E PRESENÇA DE ESPÍRITO EM WALTER BENJAMIN
Authors: Conceição Nélio
Published: October 2022

RESUMO O presente artigo debruça-se sobre o papel que o conceito de “presença de espírito” (Geistesgegenwart) desempenha no pensamento de Walter Benjamin, aprofundando linhas de interpretação que se articulam com outros conceitos relevantes, como os de “atenção” (Aufimerksamkeit) ou “tempo do agora” (Jetztzeit). São analisados os elementos da obra de Benjamin que desenvolvem a importância filosófica da presença de espírito, sublinhando-se a sua dimensão corpórea e a sua pertinência estética e crítica. A análise incide sobre cinco linhas de interpretação que de diferentes modos se entrecruzam: (i) a presença de espírito é uma forma de pensamento/acção que deve ser cultivada como modo de lidar com a vivência do choque; (ii) ter presença de espírito é uma atitude que pode ser exercitada; (iii) “agarrar o dia” envolve o corpo e pressupõe uma experiência do tempo intensivo; (iv) a presença de espírito é uma instância conceptual que integra elementos relativos ao jogo; (v) valorizando o presente, a presença de espírito implica uma relação entre perigo e gesto crítico – na reflexão histórica e política de Benjamin, esse gesto entrelaça a dimensão individual e a dimensão colectiva.
ACONTECIMENTO, MUNDO E ENTE INTRAMUNDANO: ALGUNS PROBLEMAS NA FILOSOFIA DA ARTE DE MARTIN HEIDEGGER
Authors: Grupillo Arthur
Published: October 2022

RESUMO O objetivo do artigo é caracterizar, tão precisamente quanto possível, a filosofia da arte de Martin Heidegger a partir de seus distanciamentos para, em seguida, delinear um problema que nos parece estrutural. Com a noção de acontecimento [Ereignis], Heidegger pretende distinguir sua perspectiva sobre arte principalmente de outras duas, a saber, a da tradição neokantiana e a de Hegel. Isso nos permite ter uma dimensão da radicalidade conceitual de Heidegger, na medida em que o acontecimento pretende apontar um momento poético anterior ao linguístico, também compreendido como abertura de um mundo. Esse momento, contudo, escapa às relações de referência previstas na noção de mundo e se torna praticamente indizível. Além disso, a obra de arte que abre um mundo não deixa também de poder ser identificada como um ente intramundano, enredando, assim, a própria perspectiva de Heidegger em uma série de dificuldades aparentemente incontornáveis.
Classifiers can be for numerals or nouns: Two strategies for numeral modification
Authors: Little Carol-Rose , Moroney Mary , Royer Justin
Published: October 2022

This paper compares two families of theories for numeral classifiers drawing on fieldwork data from two languages, Ch’ol (Mayan, Mexico) and Shan (Kra-Dai, Myanmar). We discuss classifier-for-numeral theories and classifier-for-noun theories, which we argue make different predictions based on the syntactic position and semantic contribution of the classifier in each set of theories. We argue that Ch’ol is a classifier-for-numeral language and Shan is a classifier-for-noun language. This analysis attributes the distinction between classifier-for-numeral and classifier-for-noun languages to cross-linguistic variation in the strategies for numeral modification. The proposed diagnostics are based on the semantic role of the classifier in numeral modification and can be used to distinguish between the two types of numeral classifiers across other languages.

Introduction : les pathologies non fracturaires du genou sont fréquemment rencontrées en opérations extérieures et représentent une cause fréquente d’évacuation médicale stratégique. L’objectif de ce travail était d’évaluer la concordance entre le diagnostic initial, réalisé avec les moyens limités des structures médicales de l’avant, et le diagnostic définitif. Matériel et méthodes : une étude rétrospective observationnelle, longitudinale, multicentrique a été menée chez les patients militaires ayant bénéficié d’une évacuation stratégique vers les hôpitaux militaires parisiens entre janvier 2011 et décembre 2015. Le diagnostic initial, posé sur le terrain, au Role 1 ou 2, a été comparé au diagnostic définitif posé au Role 4. Résultats : un total de 104 patients a été inclus durant la période d’étude. Il existait une concordance diagnostique statistiquement médiocre entre le diagnostic initial et définitif. Discussion : cette étude est la première à évaluer la concordance diagnostique pour les pathologies du genou non fracturaires entre le terrain et le Role 4. Les voies d’amélioration résident entre autres dans l’usage d’une fiche diagnostique spécifique et dans l’optimisation de la formation à la médecine du sport pour les internes de médecine générale militaires.
Zaman gecikmeli sistemler için Padé yaklaşımı ve kesirli dereceli PI kontrolör için yeni bir tasarım metodu
Authors: ÖZYETKİN Münevver Mine , ASTEKİN Dorukhan
Published: October 2022

Kesirli dereceli PI kontrolörler, günden güne getirdiği kolaylıklar sayesinde birçok makalenin araştırma konusu olmuştur. Bu tür bir kontrolör tam sayı dereceli PI ile karşılaştırıldığında çok daha faydalı sonuçlar sunar. Fakat işlemleri daha karmaşık bir hale getirir. Bu çalışmada kararlılık sınır eğrisi metodu kullanılarak geliştirilmiş olan dışbükey kararlılık bölgesinin ağırlık merkezine dayalı basit bir kesirli dereceli PI kontrolör tasarım yöntemi önerilmiştir. Bunun için önce kesirli dereceli PI kontrolörün parametre düzleminde tüm kararlı kontrolörleri sağlayan kararlılık bölgesi elde edilir. Daha sonra bu kararlılık bölgesinin köşe ve tepe noktaları belirlenerek dışbükey kararlılık bölgesi elde edilir. Son olarak elde edilen dışbükey kararlılık bölgesinin ağırlık merkezi bulunarak kontrolör parametreleri hesaplanır. Kullanılan yöntem, kontrolör parametrelerinin karmaşık grafiksel yöntemler kullanılmadan hesaplanması, kapalı döngü sisteminin kararlılığını sağlaması ve hesaplama yükünü oldukça azaltması bakımından önemli avantajlar sağlamaktadır. Ayrıca, bu çalışmada kararlılık bölgesinin elde edilmesinde kullanılan denklemler için literatürdeki çalışmalardan farklı olarak zaman gecikmesi terimi yerine Padé yaklaşımlarının kullanılması tercih edilmiştir. Özellikle ikinci dereceden Padé yaklaşımı kullanılarak elde edilen sonuçların neredeyse orijinal sistemle birebir örtüştüğü görülmektedir. Önerilen yöntemin etkinliğini ve basitliğini göstermek için bazı sayısal örnekler verilmiştir.
BIND&MODIFY: Long-range single-molecule mapping of chromatin modification in eukaryotes. V.2 v1
Authors: Weng Zhe
Published: October 2022

Here we describe a powerful method, BIND&MODIFY, for probing histone modifications and transcription factors at single molecular level. This is the Protocol V2. Our approach used the recombinant fused protein A-M.EcoGII, which tethers the methyltransferase M.EcoGII to the protein binding sites and locally labels the neighboring DNA regions via artificial methylations. This method could reveal ingle-molecule heterogenous histone modification status and CpG methylation at the same time, and could enable quantify the correlation between the distal elements. Further applications based on this method's concept could be applied to probe multiple protein binding events on the same single molecular DNA. The method proposed herein may soon become an essential tool for third-generation sequencing in the future.

Abstract Background Life expectancy and quality of life of people living with HIV have been dramatically improved after introducing antiretroviral therapy, and the prevalence of non-communicable diseases has increased. Several studies have found that hyperglycemia with or without type 2 diabetes was associated with poor outcomes in people living with HIV. The study’s objective was to determine the prevalence of hyperglycemia and assess its impact on mortality. Materials and Methods A retrospective cohort study was conducted among people living with HIV diagnosed in 2012-2018 and followed through 2020 at the Infectious Diseases, AIDS and ClinicalImmunology Research Center in Tbilisi, Georgia. Primary outcomes of interest included the prevalence of hyperglycemia and mortality. Causes of death were classified according to the Coding of Death in HIV(CoDe) protocol. Results Our study included 2914 people living with HIV. Two hundred and forty-two (8.3%)patients had hyperglycemia, with an increasing prevalence by age. Three hundred one(9.7%) participants died over the median 3.71 (IQR: 2.14-5.37) years of follow-up. Among these, 139 (46.2%) were due to AIDS-related causes, 123 (40.9%) – were due to non-AIDS causes, and in 39 (12.9%) cases, the cause of death could not be determined. Overall, the cohort contributed to 11,148 person-years offollow-up (PYFU), translating into a mortality rate of 2.70 deaths per 100 PYFU. The mortalityrate was significantly higher among individuals with hyperglycemia - 11.17 deaths per 100PYFU vs 2.07 deaths per100 PYFU amongnormoglycemicpatients(p<0.0001).Conclusions Hyperglycemia was associated with increased odds of mortality. Screening andmanagement of hyperglycemia should be integrated into routine HIV clinical services as part of acomprehensivecarepackage.

Characterization of the VKORC1 and CYP2C9 genotypes v1
Authors: Causevic Mirsada
Published: October 2022

Vitamin K antagonists are anticoagulants which represent widely prescribed drugs for prevention and treatment of thromboembolic disorders. The molecular target of these drugs is vitamin K epoxide reductase enzyme and their metabolism is performed by the cytochrome P-450 2C9 enzyme, both of which are encoded by polymorphic genes - vitamin K epoxide reductase complex subunit 1 (VKORC1) and cytochrome P-450 2C9 (CYP2C9), respectively. Identification of VKORC1 and CYP2C9 genotypes was recommended by the U.S. Food and Drug Administration in 2007, in order to guide the initial dosing of warfarin, the first oral vitamin K antagonist drug, to achieve optimum anticoagulation and prevent hemorrhagic events. This protocol is designed for undergraduate students of pharmacology or medicine, or anyone receiving training in pharmacogenomics/pharmacogenetics and understanding a relationship between a gene and drug response for the first time. The protocol represents a step-by-step guide to using polymerase chain reaction restriction fragment length polymorphism (PCR-RFLP) method in determining VKORC1 -1639G>A, CYP2C9*1/*1, CYP2C9*1/*2, CYP2C9*1/*3, and CYP2C9*2/*3 genotypes. Based on the combination of the VKORC1 -1639G>A and CYP2C9 genotypes, that is, the pattern of DNA fragments, which are visualized using agarose gel electrophoresis and DNA staining, a conclusion on an individual’s sensitivity to vitamin K antagonists and appropriate drug dose is reached.

In spite of importance of tribology of solids with surface roughness, there is no synthesized theory covering adhesion yet. One of the methods to describe adhesion in tribological systems is the Green's Function Molecular Dynamics (GFMD). This work aims at reviewing the most recent GFMD techniques and applications of GFMD in contact mechanics. There are different attributes of this method that are important for its realization: model to describe surface roughness, model to describe interfacial forces, constitutive model to describe the solid deformation and algorithm to minimize surface potential energy. We organize this review using the following set of parameters: degrees of freedom of the system modelled, substrate geometry, loading control, material properties, surface topography, interfacial interaction models.

Published: October 2022

Massive Open Online Courses (MOOCs) have been around for some time, but several studies highlighted different issues associated with them, including quality. The COVID-19 pandemic catalyzed their second blooming, where MOOCs have seen a surge in enrollments since March 2020. This study intended to explore how this enrollment reflected on the research studies included in scientific publications, indexed by Web of Science. Specifically, the bibliometric mapping analyses of 108 studies have revealed an ongoing trend in the countries contributing to the MOOCs research, namely USA, China, UK and Spain. Additionally, MOOCs research coming from US, UK and other western countries was decreasing before the pandemic and showed a continuous dramatic reduction also during the COVID-19 pandemic. Growing attention in MOOCs research among less represented countries was also observed. Besides, most of the topics focused on by MOOCs research during the pandemic were mainly related to education and engineering.

Education in medical sciences, including nursing, has encountered numerous challenges following the worldwide outbreak of coronavirus disease 2019 (COVID-19). Additionally, students’ satisfaction with the methods of instruction can be accompanied by improved learning outcomes. This study aimed to investigate the nursing students’ satisfaction with the quality of courses (SQC) and satisfaction with virtual learning (SVL) during the COVID-19 pandemic. This cross-sectional study was conducted at a nursing school (105 nursing students) in Tehran,Iran, in the first semester of 2020-2021. The individual characteristics questionnaire, the Course Experience Questionnaire (CEQ), and the e-Learning Satisfaction Questionnaire (e-LSQ) were used for data collection. More than 88% of the nursing students were satisfied with the quality of the courses. The level of SVL in 57.1% of them was moderate. Among the individual variables, only the academic semester was regarded as a predictor of SQC (p=0.025). There was no significant relationship between the dimensions and the total score of CEQ with students’ academic achievement (p<0.05). Additionally, all the CEQ dimensions were significant predictors of the nursing students’ SQC (p<0.001). Given the unknown time of eradicating COVID-19, it is necessary to adopt appropriate policies and perform proper planning to continue better nursing education and increase student satisfaction.
EXPLORING TEACHERS’ VIEWS ON EMOTION TRANSFER IN VIRTUAL CLASSROOMS DURING EMERGENCY REMOTE TEACHING
Authors: DUZGUN Serkan
Published: October 2022

The present study explored emotion transfer-related views of teachers holding online classes in emergency remote teaching during the COVID-19 pandemic. We carried out the study with 630 teachers, the majority of whom were primary school teachers, serving at public and private K-12 schools. This was a descriptive survey study as it described the teachers’ views as they were. The data were collected using the “Emotional Presence in Online Learning Scale” (EPOLS) and analyzed using descriptive statistics, independent sample t-test, and one-way analysis of variance (ANOVA). The findings revealed that the majority of teachers used the EBA Virtual Classroom application in emergency remote teaching while a small number of them utilized other virtual classroom applications. In addition, the teachers reported using messaging applications effectively, but it was not the case for social media. The private school teachers found virtual classroom applications efficient in transferring (conveying and receiving) emotions compared to public school teachers. The scores on the EPOLS and receiving emotions subscale pointed out that the female teachers found virtual classroom applications more effective than their male counterparts. Moreover, it was found that the preschool teachers and classroom teachers found virtual classroom applications more effective in receiving emotions than the high school teachers and middle school teachers, respectively. Finally, those with undergraduate and postgraduate education recognized emotion transfer in virtual classrooms more efficient than the teachers with an associate degree.

COVID-19 pandemisiyle birlikte kapanmalar ve yasaklar, bireylerin internet kullanımlarını hem gündelik yaşam hem de iş yaşamlarında önemli bir noktaya taşımıştır. Bu makalede, Necmettin Erbakan Üniversitesi’nde görevli idari personellerin pandemi sürecinde, gündelik yaşamlarındaki ve iş yaşamlarındaki internet kullanım pratikleri araştırılmıştır. Uzaktan çalışma süreçleriyle birlikte ortaya çıkan avantaj ve dezavantajlar nitel bir saha araştırması ile keşfedilmeye çalışılmıştır. Bireyler, uzaktan ve hibrit çalışma sürecinde, işlerinin gereği olarak internette çok daha fazla zaman geçirmek, pandemi öncesinde kullanmadıkları bazı uygulamaları kullanmak durumunda kalmışlardır. Üniversitenin idari birimlerinde görevli 18 katılımcı ile gerçekleştirilen nitel görüşmeler aracılığı ile toplanan saha verileri üzerinden tematik analiz gerçekleştirilmiştir. Bu analiz neticesinde, idari personellerin pandemi sürecindeki internet kullanımlarını çoğunlukla mobil telefon üzerinden gerçekleştirdiği tespit edilmiştir. Bu dönemde en çok kullanılan mobil uygulamaların yemek ve alışveriş uygulamaları olduğu, aile üyeleri ve sosyal çevre ile çevrimiçi görüşmelerin rutin haline geldiği görülmüştür. Öte yandan, internet aracılığıyla uzaktan çalışmanın virüse yakalanma riskini azaltması nedeniyle büyük bir avantaj, ev ve iş yaşamının sınırlarını ortadan kaldırması dolayısıyla ise bir dezavantaj olarak algılandığı bulgulanmıştır. Bu makale ile Türkçe literatürde ilk kez, pandemiyle birlikte üniversite idari personellerinin eve kapanma ve uzaktan çalışmaya bağlı internet kullanım pratikleri keşfedilmeye çalışılmıştır.

Estimación del estado de carga de baterías de flujo redox con caudales desequilibrados.
Authors: Clemente Alejandro , Cecilia Andreu , Costa-Castelló Ramón
Published: October 2022

Este artículo presenta el diseño de observador de estado para estimar, en línea, el estado de carga de una batería de flujo redox. Una limitación de los algoritmos existentes, hasta el momento, es que asumen una misma concentración de especies en los tanques y las celdas. Esta condición raramente se cumple en la realidad. Por ello, este trabajo presenta un nuevo estimador que es capaz de diferenciar entre la concentración dentro de los tanques y la celda de la batería. El modelo utilizado para el diseño del observador es un modelo electroquímico no lineal que obedece las leyes de conservación de masa y carga. Para estudiar la viabilidad del estimador se realiza un primer análisis de observabilidad. Sobre la base de dicho análisis, se propone un observador no lineal que, finalmente, se valida mediante simulación numérica.
Un enfoque de control libre de modelo para el control de temperatura en hornos solares

Published: October 2022

En el contexto de síntesis de materiales y pruebas de estrés térmico, los hornos solares cobran un papel fundamental. Estos sistemas experimentales se suelen operar normalmente de forma manual por operadores cualificados. Sin embargo, el uso de controladores automáticos puede ser esencial para tener en cuenta las diferentes dinámicas de las piezas tratadas, seguir los diferentes perfiles de temperatura requeridos en las pruebas y hacer frente a la intermitencia de la fuente principal de energía, la energía solar. Sobre estas bases, el presente trabajo propone un sistema de control libre de modelo sencillo y con pocos parámetros de ajuste para el control de temperatura en hornos solares. El controlador se basa en la metodología Extremum Seeking Control (ESC) y se complementa con un controlador por adelanto en configuración serie para el rechazo de perturbaciones de radiación. La estrategia propuesta se ha probado en simulación en un modelo validado del horno SF60 de la Plataforma Solar de Almería, usando datos meteorológicos reales de dicho emplazamiento. A pesar de que la técnica ESC puede tener problemas de convergencia en presencia de perturbaciones rápidas, la inclusión del controlador por adelanto en serie hace que los resultados obtenidos pongan de manifiesto el buen desempeño del controlador, tanto para el seguimiento de referencias como para el rechazo de perturbaciones. Además, evidencian su fácil sintonía, lo que puede llegar a ser fundamental para su uso en la práctica por operadores que no sean expertos en el campo de la ingeniería de control.

Published: October 2022

Resulta difícil encontrar un equipo de laboratorio que permita la emulación del comportamiento de un aerogenerador, ya sea con objetivos docentes, investigadores o técnicos, por ejemplo, para el desarrollo de sistemas de control. Este trabajo presenta el control de un emulador de una turbina eólica, que combina un generador eléctrico real con las componentes aerodinámicas y mecánicas simuladas. La parte experimental consiste en un generador de inducción doblemente alimentado (DFIG) de pequeña potencia (1 kW) cuyo eje de rotación está unido de forma solidaria a un servomotor brushless de corriente continua. Este actúa de motor de arrastre emulando el par aerodinámico siguiendo un modelo no lineal. Dicho modelo también incluye el comportamiento del viento, de forma que se puedan simular condiciones reproducibles. Se ha implementado una estructura de control multivariable descentralizado con la que controlar las principales variables de un aerogenerador de velocidad variable, paso de pala variable con DFIG, en la que se ha realizado un análisis previo de la interacción existente entre las variables implicadas. Los resultados en los ensayos experimentales confirman que el emulador es capaz de reproducir el comportamiento de los aerogeneradores reales de mayor potencia y sirve de banco de ensayos tanto para fines docentes como para diseño de sistemas de control.
Ajuste multiobjetivo de controladores robustos considerando soluciones casi óptimas relevantes

Published: October 2022

En este trabajo se muestra la utilidad de las soluciones casi óptimas relevantes en el ajuste mediante optimización multiobjetivo de controladores robustos ante incertidumbre en el modelo. Una posibilidad muy común para este ajuste es incorporar la incertidumbre en el proceso de optimización, por ejemplo, incorporando la evaluación de la robustez durante el proceso. El principal problema de este enfoque es que tiene un alto coste computacional. Para evitar este problema, en este trabajo se propone analizar la incertidumbre en la etapa de decisión tanto para las soluciones óptimas como para las casi óptimas relevantes. Estas soluciones alternativas proporcionan mayor diversidad, pudiendo resultar controladores más robustos que los óptimos. Se muestra un ejemplo de diseño multivariable mediante dos controladores PI. El proceso a controlar es un modelo lineal de dos entradas y dos salidas donde la incertidumbre se ha modelado con un conjunto de cincuenta escenarios (posibles modelos alternativos). El ejemplo muestra que existen zonas de prestaciones en las que los controladores casi óptimos relevantes pueden obtener una mayor robustez que los controladores óptimos.

Geolocated Wireless Heart Rate Variability Sentinel Surveillance in Immunological Assessment, Intervention and Research Concerning COVID-19 and other Pandemic Threats
Authors: Drury Robert
Published: October 2022

With the development of increasingly sophisticated biotechnology and conceptual/analytic approaches, a greater ability to understand, intervene and prevent disease and promote health is becoming more available. A synthetic integration of several such technologies and analytic strategies named the Canary System is described which can impact significant global health problems, including the COVID-19 pandemic with its continuously evolving variants. The system wirelessly acquires high fidelity heart rate variability and other data, geocodes the data and transfers It through personal device for high throughput algorithmic analysis, which has been shown to indicate likely COVID-19 status well before clinical symptoms emerge, if indeed the individual becomes symptomatic. The system can not only provide sentinel surveillance and other public health activities, but can facilitate research in disciplines such as immunology, virology, epidemiology, affective and cognitive neurobiology and health psychology. The aim and scope of this paper is to, within context, describe both the rationale and functional components and operation of this system in a variety of settings. The objective of the paper is to explicate both the operational characteristics of this approach and the multiple applications it may have in the disciplines identified above as well as primary health care and non-medical applications.

Published: October 2022

Coronavirus Infectious Disease 2019 (COVID-19) is caused by the Severe Acute Respiratory Syndrome Coronavirus-2 (SARS CoV-2) that emerged as a novel pathogen of global concern in the latter stages of 2019. COVID-19 is a highly contagious disease which can be transmitted through aerosol droplets and surface-to-host contact. Both symptomology and the severity of disease can vary wildly between individuals, from asymptomatic but infectious, to those that require critical care. Due to the neoteric emergence of SARS-CoV-2, current treatment strategies are not yet well developed and rely on the repurposing of such medications as antiviral, corticosteroid, immunosuppressant and oxygen (O2) therapies. However, the minimal efficacy of these interventions is concerning. In addition to the acute infection that prevails, it is estimated that up to 30% of adults who contract COVID-19 develop chronic symptoms lasting longer than 12 weeks. It is also estimated that 15% of children aged 2-16 years have developed long-lasting sequelae associated with SARS-CoV-2 infection. According to recent clinical data, molecular hydrogen (H2) and oxy-hydrogen (H2/O2) therapies successfully remediated the debilitating effects of SARS-CoV-2 infection in adults. By acting as an effective anti-inflammatory and antioxidative agent, it is reported that H2 administration can improve recovery through abatement of the hyperinflammatory cytokine cascade and reduction of inhalation resistance in patients with mild-moderate disease symptoms. In this review, the authors investigate the clinical and empirical evidence relating to treating the symptoms of both acute and chronic COVID-19 with H2-containing therapeutics.
Immersive imulation and Paramedicine Students’ Situational Awareness: A Mixed-Methods Pilot Study
Authors: Williams Brett , Beovich Bronwyn , Olaussen Alex , Hunter Justin
Published: October 2022

Background: Situational awareness involves the ability to recognise and interpret environmental cues and utilise this to predict future events. It is an important factor in the minimisation of human error in many settings, including healthcare. It is especially relevant within paramedic practice where the situation may be highly dynamic. Simulation-based education is increasingly used within paramedicine education and has been demonstrated as effective for the development of situational awareness in healthcare professionals. Aims: The primary aim of this study was to evaluate the level of situational awareness in undergraduate paramedicine students during an immersive simulation compared to that during a more conventional, non-immersive scenario. A secondary aim was to examine student perceptions of situational awareness, as well as their experiences of the simulations in which they participated. Methods: Third-year paramedicine students at an Australian university participated in two simulated emergency scenarios; one in an immersive setting, and one in a non-immersive environment. The Situation Awareness Global Assessment Technique was utilised to assess their level of situational awareness at various pre-determined points in each scenario. Subsequently, semi-structured interviews were utilised to examine student perceptions of situational awareness as well as their experiences of the simulations. Results: Overall, students (n=18) demonstrated lower levels of situational awareness in the immersive simulation compared with the non-immersive simulation. Most errors occurred in the initial stages, within the ‘recognition’ component of situational awareness. Eight students participated in follow-up interviews, with the majority expressing that the immersive nature of the simulation adversely affected their scenario management. They reported difficulty in recall of basic knowledge, disorganisation of thoughts and clinical approach, and being able to concentrate only on one thing at a time. Conclusion: Paramedicine students in our study demonstrated lower levels of situational awareness during an immersive simulated scenario compared with a conventional non-immersive setting, particularly in the initial ‘recognition’ stage of situational awareness. As a lack of situational awareness may contribute to healthcare errors, its assessment and development must be addressed within paramedicine education. The utilisation of immersive simulation in paramedicine curricula may play an important role in this area.

Published: October 2022

Background: Breast Cancer is one of the most common cancers that occur universally among women. The disability-adjusted life years lost by women to breast cancer globally are more than any other cancer. Breast cancer occurs in women worldwide after puberty with increasing rates in later life. Improvements in breast cancer survival began in the 1980s in countries where early detection programs combined with different modes of treatment to eradicate the invasive form of the disease are practiced. Recent data show a higher prevalence of breast cancer among women in Northern Uganda compared to the rest of the country. This study aimed to determine factors associated with breast cancer awareness, breast self-examination, clinical breast examination, and other modalities for screening and early breast cancer detection among adult women in Gulu Main Market. Methods: We conducted a cross-sectional study in Gulu's Main Market in 2020. We recruited Ninety-eight adult women for the study using a random sampling method. The questionnaire had an internal validity of Cronbach's α=0.72, and a local IRB approved the study. We used SPSS version 26.0 for data analysis, and a p-value less than 0.05 was considered significant. Results: Most participants were 20-29 years 41(41.8%), married 44(44.9%), monthly incomes of more than one million shillings 51(52.2%), Acholi 81(82.7%), Catholics 46(46.9%), vendors 75(76.5%), work duration in the Market (1-10 years) 64(65.4%), primary level of education 39(39.8%), and had 1-2 pregnancies 37(37.8%). The independent factors associated with breast cancer awareness, breast self-examination, and clinical breast examination were vendor (primary occupation) (β=-0.130, t=-2.979, p=0.004), work duration in the Main Market (1-10 years) (β=-0.186, t=-2.452, p=0.016), and the highest level of education (β=-0.091, t=-2.506, p=0.014). Conclusions: Breast cancer awareness and downstaging practices among adult women in Gulu's Main Market are thought-provoking. Women with better socioeconomic status (higher education level, moderate work duration in the Market, and vendors) in Gulu Main Market were more likely aware and practiced breast cancer downstaging activities. There is a need to strengthen publicity on breast cancer-related knowledge for lower-income occupational groups and those with lower educational levels to understand better the importance of conducting early breast cancer detection activities.

Published: October 2022

O Estágio Supervisionado é, diferentemente de outras disciplinas, uma atividade realizada presencialmente na escola parceira da instituição de ensino onde o licenciando cursa sua graduação. Um dos objetivos, o principal deles, é a ambientação desse aluno, futuro professor, no complexo espaço físico da formação escolar, microcosmo da sociedade. A vivência nesse ambiente sempre foi considerada de grande poder formador. No entanto, durante a pandemia do Novo Coronavírus, e diante do fechamento das escolas devido ao risco de contaminação de alunos, professores, funcionários e demais atores dessa comunidade, foi necessário pensar-se em mudanças. Sendo assim, a Coordenação das Disciplinas Pedagógicas das Licenciaturas viu-se obrigada a adaptar e estágio supervisionado para o ambiente remoto, com o objetivo de evitar a postergação da preparação do licenciando para sua futura atuação no magistério. Além disso, a crescente demanda por profissionais docentes com vivência em tecnologias de apoio à educação apresentou-se como oportunidade de produção de conteúdo formador para estes novos ingressantes na carreira. Desse modo, foram propostas e realizadas atividades, como fóruns, entrevistas, análise de livros, gravação de videoaulas etc., que proporcionaram ganho formativo e diferencial aos alunos.
