Authors: Mi Huichao , Gao Zhanghao , Zhang Qiaorong , Zheng Yafeng
Published: April 2022

Learning performance prediction can help teachers find students who tend to fail as early as possible so as to give them timely help, which is of great significance for online education. With the availability of online data and the continuous de-velopment of machine learning technology, learning performance prediction in large-scale online education is gaining new momentum. In order to understand the performance of different machine learning algorithms in predicting multi-category learning performance in large-scale online education, this study com-pares five machine learning algorithms including logic regression, decision tree algorithm, naive Bayes, support vector machine and deep neural network. Based on 100000 data records in the edX open dataset, this study models and forecasts students' learning performance with six online learning behaviors as the eigenval-ues. In the process of modeling, missing value estimation and normalization pre-processing are carried out on the original data at first. After that, six datasets of different sizes are divided as input data. Next, the performance of the five algo-rithms is tested on data sets of different sizes. Finally, SFS, SBS and multiple re-gression analysis are used to explore the effect of behavioral feature selection on algorithm performance. The research was validated and evaluated by three met-rics: precision, recall and F1 score. The results show that the F1 score of the deep neural network with multiple regression analysis feature selection achieves 99.25% in the large-scale dataset, outperforming the related other models by 1.25%.

Development of Educational Kit for Practical Course in the Topic of Phase-Shift RC Oscillator
Authors: Fuada Syifaul
Published: April 2022

This research develops a phase-shift RC Oscillator trainer kit that can be used to give undergraduate students an understanding of one of the materials related to analog circuit practicum. The Oscillator is one of the essential subtopics to be examined thoroughly by electrical engineering students. Furthermore, the Resistor and Capacitor modules were provided separately to be connected to the trainer through jumper cables. The phase-shift RC circuit in the trainer kit used a single Op-Amp 741 while the Network model utilized an Inverting Amplifier to determine the gain which must be ≥ 29 times, therefore, Rfeedback ≥ 29 Rgain (Rfeedback = 30 kΩ and Rgain = 1 kΩ). Two tasks in this learning media were completed by students, namely measuring the output frequency and observing the phase shift. The output signal on this trainer kit was observed using only an Oscilloscope and a frequency counter. The phase inverter of the phase-shift RC Oscillator adjusts the output signal by 180o and sends feedback to the input, therefore, there is positive feedback. Meanwhile, the trainer kit had an output frequency specification of ~649 Hz (C = 100 nF, R = 1 kΩ) and it shifts the phase by 60o on each RC network. Using 2 and 3 R-C networks, the phase shifts were 120o and 180o, respectively. The trainer kit was packaged in a box made of acrylic with dimensions l x w x h = 20 cm x 28 cm x 5 mm. Through a questionnaire consisting of 13 criteria, this trainer kit was declared valid, namely r count > 0.2960 (5%) and reliable (Cronbach's alpha > 0.60, which was 0.732) to be used as a learning media based on user responses, namely students (N = 35). In the context of technical education, this trainer kit also supports the efficient implementation of practicum without compromising the learning objectives due to the ease of operation (plug & play through jumper cables) compared to fully assembling the circuit using a project board.

Pour un renouveau des études sur la Renaissance érudite française
Authors: Sanchi Luigi-Alberto
Published: April 2022

En dépit de la splendeur intellectuelle, philologique, éditoriale de l’humanisme français à la Renaissance, de trop nombreux ouvrages ne font toujours pas à ce jour l’objet d’éditions scientifiques, ni de travaux d’analyse. Si certains auteurs sont très bien servis par la recherche universitaire, notamment ceux qui se sont exprimés en français, la foisonnante richesse de la production néolatine – pour ne rien dire de la néogrecque – demeure largement sous-exploitée, voire inexplorée, malgré l’existence de quelques pôles d’études et l’intérêt d’un petit nombre d’étudiants. Un rapide tour d’horizon permet de mieux plaider la cause d’un pan très illustre du Seizième siècle en France souvent laissé dans l’ombre.
Quête muséographique de l’Autre. Les enjeux symboliques de pratiques touristiques à vocation « culturelle » au Sénégal
Authors: Quashie Hélène
Published: April 2022

La promotion du « tourisme culturel » à destination du continent africain s’appuie sur de nombreuses images issues et adaptées de récits de voyages et de l’ethnologie classique. Teintées de références évolutionnistes et primitivistes, celles-ci alimentent une quête des origines et d’un « monde perdu », aujourd’hui largement répandue, accentuée, détournée, ou renforcée par ce même phénomène touristique. La destination Sénégal propose très peu de spécificités culturelles exploitables par les voyagistes ; elle s’ouvre pourtant de manière accrue aux marchés de la « découverte authentique » et de la « rencontre de l’Autre ». L’analyse de discours promotionnels, des modalités d’activités « culturelles » proposées aux voyageurs, des présupposés que ceux-ci entretiennent et des perceptions locales de l’Autre-touriste auxquelles ils se trouvent confrontés révèle les ressorts symboliques et sociaux qui garantissent et encouragent le succès de ces expériences touristiques. Elle met ainsi en exergue des représentations et pratiques sociales qui soutiennent une éthique paradoxale de la connaissance de l’Autre.
Logiques habitantes et offre résidentielle dans le processus de renouvellement urbain à Marseille
Authors: Messaoudène Maha
Published: April 2022

A partir d’une démarche d’enquête ethno-méthodologique, cet article analyse comment le relogement et le post-relogement ont été perçus et vécus par les habitants de deux quartiers de la banlieue nord de Marseille (Bellevue et Bassens). Ces quartiers présentent des contrastes majeurs du point de vue de l’offre résidentielle. Bellevue, grand ensemble des années 1960 construit afin d’accueillir les populations pieds-noirs de retour d’Algérie, fait l’objet d’une dé-densification par démolition. De son côté, la Cité Bassens, construite afin de reloger les populations en provenance des bidonvilles, s’est vue remplacée par des habitations de type semi-individuel.
Tourisme culturel et patrimoine : quelques analyses pour un Monde habitable
Authors: Lazzarotti Olivier
Published: April 2022

Ce texte met en perspective les mots qui définissent le tourisme culturel, à partir des textes internationaux officiels, et les pratiques touristiques qui le qualifient. Ces deux approches révèlent deux processus de production mémorielle et de sa mise en lieux. La première est celle de la nomination par les érudits et les savants qui désignent les monuments. La seconde est celle de l’élection. Les touristes, par leur présence physique dans les lieux, activent une mémoire au moment de sa transmission : le patrimoine. Dans le premier cas, les touristes dérangent ce qui existe déjà. Dans le second cas, au contraire, les touristes font le lieu et la mémoire…
Living with Familiar Hazards: Flood Experiences and Human Vulnerability in Accra, Ghana
Authors: Aboagye Dacosta
Published: April 2022

The paper explores demographic characteristics, migration history, and impact of flooding on households and communities. The main objective is to explore the different ways in which floods impact households and communities in Accra. Specifically, the paper analyzes how floods alter the set of resources available to households and communities. The results indicate that urbanization and governmental policies have rendered more people, especially the poor and recent migrants, homeless. These homeless people have become more vulnerable to flooding than the average Accra resident. The results also show that the homeless community contrast with the fixed community in terms of socio-economic characteristics, degree of social cohesion, and physical location. The paper concludes that the unchanging pattern of vulnerability shows the inability of a society to cope and adjust to familiar hazards.
A visual model for mobility practices and learnings
Authors: Rigal Alexandre
Published: April 2022

Visualizations of the city are necessary to lead to inquiries and for designing urban and transport policies because they are needed to synthesize information, to stimulate new hypotheses, and to evoke models. However, most of the contemporary visualization models do not consider that the major paradigms in urban studies concentrate on dwelling practices. The goal of this exploratory article is to represent the practices of urban dwellers, with the aim of elaborating a method to visualize and study the evolution of practices. For this task, there is a need to translate the concepts of practice and learning into visualization. In this article, I propose a range of visualizations to render practices and learnings visible and comparable, allowing for more visual research. The visualizations are created from data gathered during interviews with inhabitants of Swiss urban regions on their daily mobility within a research project challenging the place of the car in contemporary urban spaces. By inventing representations of dweller practices, I obtain a renewed model for understanding urban spaces and practices based on learning. Finally, visualizations are used to understand urban spaces anew and to imagine urban interventions that could be beneficial to changes in mobility practices. Policy measures to reduce car use are suggested based on the model developed with the visualizations and its fundamental principles. Starting from the elaboration of a method of visualization, I propose both a theoretical inquiry of urban practices based on visual urban research and a definition of the city based on learning to orient urban designs in favour of more paedagogical thinking.
La mécanique du piston. Perspectives théoriques en physique de l’ascension socio-professionnelle
Authors: Matthey Laurent , Walther Olivier
Published: April 2022

Cet article souhaite interroger la physique de l’ascension sociale. En prenant pour analogie la course d’un piston dans un moteur à explosion, il se donne pour ambition, en premier lieu, de questionner les modalités de production et de reproduction des classes sociales dans le domaine professionnel. Littéralement, le « piston » est bien une pièce métallique dont le parcours à l’intérieur d’un cylindre permet de produire du travail mécanique à partir d’énergie thermique. Mais il est aussi, au sens figuré attesté depuis 1857, l’instrument social qui autorise la course victorieuse des individus favorisés. Aussi, de l’admission à l’échappement, les quatre temps du mouvement du piston devraient permettre de vérifier l’hypothèse selon laquelle les candidats demeurent profondément inégaux du point de vue des chances de réussite. La seconde partie de l’article est consacrée à la discussion du modèle qui sert aujourd’hui à théoriser le monde professionnel, à savoir celui du réseau. Quels sont en effet les enjeux d’un tel glissement terminologique ? N’est-il pas en lien avec une propension à opacifier les régimes de reproduction sociale en recourant à un lexique démocratique qui postule que tout le monde bénéficie de chances égales ?
Robust Image Matching for Information Systems Using Randomly Uniform Distributed SURF Features
Authors: Ince Ibrahim Furkan
Published: April 2022

Detection of similar images taken in different perspectives is a big concern in digital image processing. Fast and robust methods have been proposed in this area. In this chapter, a novel image matching approach is proposed by using speeded-up robust features (SURF). SURF is a local feature detector and descriptor that can be used for tasks such as object recognition or registration or classification or 3D reconstruction. Successful detection of the images is achieved by finding and matching corresponding interest points using SURF features. The task of finding correspondences between two images is performed through using a novel brute-force method which uniformly generates random pairs for matching similarity. Experimental results show that the proposed method yields better results than conventional brute force methods in which at least 5% accuracy increment is obtained.
GUARDARE IL MONDO CON I NEUTRINI: IL SOLE, LA TERRA E L’UNIVERSO
Authors: Pallavicini Marco
Published: April 2022

Neutrinos are the most elusive and ubiquitous known building blocks in the Universe. Predicted by Wolfgang Pauli in 1930 and then theoretically elaborated by Enrico Fermi and Ettore Majorana in the following years, they were discovered experimentally in 1956 and since then they have never ceased to surprise us with their, sometimes disconcerting, properties. There are three different types that can transform into each other, devoid of electric charge, very light but with a very small mass, at least a million times lower than that of the electron. Although we know that they have a mass, we still do not know how much they weigh. In nature they are abundantly emitted by the Sun and stars, from the nucleus of the most active galaxies and from our planet they were produced in such abundance in the first moments of the Big Bang to the point of permeating the entire Universe with neutrinos. They are also produced in large numbers by nuclear reactors and particle accelerators, which allow us accurate and controlled studies. The neutrinos emitted by natural sources are unique messengers about the sources themselves and about the physical mechanisms that generate them. This note summarizes the main steps in the history of neutrinos, their most conspicuous properties and above all how much it has been possible to learn about the stars, the Earth, and the Sun thanks to them. Particular attention will be given to the recent results at the Gran Sasso National Laboratories obtained from the Borexino experiment which, by means of neutrinos, completed for the first time in 2020 the study of all nuclear fusion reactions that take place in the Sun, including that, minority but very important, catalyzed by the presence of Carbon, Nitrogen and Oxygen in the Sun’s core.

Published: April 2022

We report a pediatric case of unilateral acute idiopathic maculopathy (UAIM) associated with West Nile virus (WNV) infection. A 10-year-old child with a 15-day history of presumed acute viral encephalitis, complained of blurred vision in the right eye. Clinical and multimodal imaging findings, including disruption of the foveal ellipsoid zone (EZ) with preservation of the external limiting membrane on Swept Source OCT (SS OCT), were consistent with UAIM. The finding of associated curvilinear chorioretinal lesions in the setting of encephalitis led a diagnosis of WNV infection to be considered and subsequently confirmed by serology. The EZ spontaneously restored over a few weeks with near complete visual recovery. This is a unique pediatric case of UAIM associated with serologically proven WNV infection.

Published: April 2022

The Aging Study of Pyeongchang Rural Area (ASPRA) is a population-based, prospective cohort study of older adults in Pyeongchang, South Korea. Since the initial enrollment of 382 participants, the ASPRA has been maintained and has conducted comprehensive geriatric assessments annually, gradually expanding its population and coverage area. As a cohort study of aging-related conditions and their functional consequences, the ASPRA leveraged Pyeongchang’s relatively low annual population movement rate and its healthcare delivery system, which was largely maintained by community health posts. Since its establishment, the ASPRA has reported numerous observational and multicomponent intervention studies on functional decline, geriatric syndrome, and frailty. Here, we discuss the findings and perspectives of ASPRA studies. We hope that the ASPRA enables the further implementation of a longitudinal study design on geriatric parameters and the development of public health strategies targeting aging-related conditions, especially in resource-limited community settings.
El derecho a la recreación en Argentina y su reconocimiento en los marcos jurídicos provinciales
Authors: Griffa Marcos
Published: April 2022

El presente artículo forma parte del proyecto de investigación “Políticas públicas de recreación en la Provincia de Córdoba”, que se lleva adelante desde la Facultad de Educación Física de la Universidad Provincial de Córdoba, Argentina. Además del análisis de las políticas públicas y de las estructuras institucionales desde las cuales se diseñan e implementan, se considera necesario indagar en los marcos jurídicos en los que se reconoce el derecho a la recreación. En esta oportunidad se procura realizar un rastreo exploratorio respecto a la presencia de este derecho en las constituciones provinciales de Argentina. Para ello se realiza una primera aproximación a partir de una indagación documental en 35 textos normativos: la Constitución Nacional de la República Argentina, los 10 tratados internacionales ratificados en ella, y las 24 constituciones jurisdiccionales del país. Según lo indagado, los derechos a la recreación, al esparcimiento, al descanso y al tiempo libre están presentes en la mayoría de las constituciones provinciales, como materia a legislar, como actividad de interés social, en los derechos reconocidos a la niñez, la juventud y la ancianidad, como competencia atribuida a los municipios o articulados a las políticas educativas.

O desejo de corpos perfeitos e problemas relacionados à insatisfação corporal são frequentes e representam crescente preocupação da saúde pública, constituindo temática importante para pesquisas. O presente estudo trata-se de um ensaio considerando pesquisas que envolvem a avaliação da imagem corporal. É intenção propor reflexões, contribuindo para área de conhecimento e formação de pesquisadores. O texto objetiva refletir, por meio de evidências conceituais e empíricas, conceitos, instrumentos e critérios de classificação aplicados aos estudos que avaliam insatisfação corporal em universitários no Brasil. Foram apontadas questões acerca dos termos envolvidos nos estudos de insatisfação corporal. No que diz respeito aos conceitos, foi possível observar uma variedade de termos relacionados que podem apontar confundimentos entre a imagem corporal, insatisfação corporal e suas dimensões perceptivas e atitudinais. Em relação aos instrumentos, predominam em estudos o uso das escalas de figuras e silhuetas e o Body Shape Questionnaire (BSQ). Estes, apesar do mesmo constructo(insatisfação corporal), apresentam formas de avaliação e classificação distintas. Em relação aos estudos, foram encontradas associações de insatisfação com as variáveis de sexo, estado nutricional, peso e com o público de universitários. Espera-se que pesquisadores da temática façam corretas distinções das dimensões, conceitos e instrumentos (com seus critérios de classificação) visando a uma maior padronização e comparabilidade entre os estudos. Conclui-se que esta temática tem sinalizado problemas, tamanho os desafios atribuídos às influências de padrões corporais cultuados socialmente.
Garrincha e o futebol: semiótica das situações de movimento do drible
Authors: Sousa-Cruz Rodrigo Wanderley de , Gomes-da-Silva Pierre Normando
Published: April 2022

O artigo objetiva analisar as significações das situações de movimento de alguns dribles de Garrincha como uma prática de linguagem oriunda de uma notória contracultura da lógica técnico-tática do futebol à época. A pesquisa é descritiva, de abordagem qualitativa, do tipo documental, sob a análise da Semiótica Pragmática da Pedagogia da Corporeidade. Foram escolhidas três cenas das Copas do Mundo de 1958 e 1962, período épico do atleta que conferiu visibilidade mundial aos seus dribles. Os resultados desvelam os dribles de Garrincha como signos de um espetáculo qualitativo, peculiar e excessivo, porque existe um caráter lúdico, que provoca uma emoção sem disfarce no uso do espaço de jogo, das relações com os oponentes e do domínio da bola com a perna direita. Conclui que seus dribles oferecem uma significação nas situações de movimento do futebol, vinculada à alegria, ao improviso dos floreios e das firulas, pois Garrincha representava uma característica da cultura futebolística brasileira generalizada, a posteriori em outros jogadores: um estilo brincante, singular e exagerado dentro do jogo.

When buying mineral fertilizer, the user expects that the content of nutrients is in the prescribed minimum values indicated on the packaging and in the declaration and that the quality of used raw materials does not have a negative impact on the environment. The analysis of a number of samples of mineral fertilizers of different quantities and ratios N, P, K showed deviations from the minimum values of nutri-ent content from the declaration as well as increased content of certain heavy metals. For that reason, it is necessary that analyzes of manufactured and imported formulations are more often controlled by the competent institutions with the prescribed method of sampling.

This review paper presents the experiences of a number of countries in the European Union (EU) and around the world that have accepted and managed to reduce sodium intake in meat products and food in general. Different procedures or their combination are in use, noting that in the strategy for the reduction of NaCl content in food, the goals can be achieved only with multi-year, systematically planned and focused activities. Close cooperation of all stakeholders is necessary, with continuous consumer education. The imperative for the success of the aforementioned strategy is to raise the awareness of the widest population at the national level, primarily consumers, as well as the scientific and professional public who transfer their desires and the results of their research and advanced technologies to the food industry.

Liposomes have been researched as carriers for encapsulation of bioactive protein hydrolysate, despite low stability which makes them difficult to use. Using cholesterol or octadecylamine as lipid membrane stabilizers, soy protein hydrolysate is effectively encapsulated in liposomes created with phospholipon. Presence of both stabilizers concurrently resulted the highest efficiency 49.7%, while increasing the phospholipon mass had no effect. Particle size was raised (265 to 335 nm) as a result of the octadecylamine addition, and zeta potential was positive (36.7 mV), as compared to the cholesterol addition (-25.1 mV). Liposomes enabled extended hydrolysate release with retained its bioactivity.

Examination of the Mental Well-Being and Coping Methods of Professional Dancers During the Covid-19 Lockdown Period
Authors: Medveczné Atinay Dorottya , Bernáth László , Pigniczkiné Rigó Adrien
Published: April 2022

The paper aims to present how professional dancers (n=163) could cope with the challenges of the lockdown period and how they could be best supported. The study measured mental well-being, resilience, coping strategies of dancers, and specific responses to the lockdown situation. The most influential factor in dancers’ mental well-being is their resilience; yet, they can also rely on their skills of coping with adversity, which, ideally, should improve during professional dancing. Of the situation-specific variables, worries and anxiety related to Covid-19, the level of boredom and the use of self-help techniques have proven to be exceptionally important. The conclusion of the research was that besides general worries related to Covid-19, the dancers are also characterized by specific worries (bodyweight control, decline in movement skills, difficulties in returning to work). It would be beneficial to put special focus on effective intervention methods for dancers, teach them adequate self-help and coping techniques, and increase their resilience. Although the lockdown period was a special and rare occurrence, similar situations, e.g. injuries, changing company, trips, having children, can frequently arise in dancers’ lives.

In modern systems for the automatic design of complex products for military equipment, algorithmic construction of conjugate models of curved surfaces using computer technologies that exclude interference are increasingly being used. This gives a powerful impetus to the development of applied geometry of surfaces and stimulates the search for new ways to improve the technological processes of manufacturing parts, on machines with an information control system. In particular, this applies to technological operations on numerically controlled machines. One of the main directions in modeling kinematic pairs should be considered the study and design of the shapes of surfaces in close connection with the operating conditions of structures in military equipment and weapons in which they are to be used. The shapes of complex curved surfaces affect the reliability and durability of mechanisms in military equipment and weapons and therefore require more careful consideration of external conditions when designing. Much attention is paid to the design of surfaces, taking into account an increasing number of predetermined requirements, conditions for the formation of curved surfaces of kinematic pairs in military equipment. The use of algorithmic constructions of conjugated kinematic pairs for an information control system in the manufacture of real surfaces of military equipment obtained as a result of stamping, the creation of a geometric model of stamping, reflecting a real physical process, is an urgent problem.
In recent years, in the manufacture of precision high-quality products of kinematic pairs and cutting tools in military equipment and weapons, complex curved surfaces have been widely used, which require the development of a geometric and mathematical apparatus for their modeling.
Algorithmic modeling of curvilinear transformations for the formation of mating surfaces of kinematic pairs in military equipment, based on a parametric kinematic screw, is proposed, which will eliminate interference during their manufacture.

Published: April 2022

Investment decisions and funding decisions taken by the company's management are directly related to the objective of financial management, namely maximizing the value of the company. The value of the company is reflected in the price of the company's shares in the capital market. Many studies analyze the effect of investment decisions and funding decisions on firm value. Research results vary. In this study, the authors examine the effect of investment decisions and funding decisions on firm value. The difference between the author's research and previous research is that the author includes the variables of asset productivity and operating activities as mediating variables. The object of research is the consumer goods sector companies listed on the Indonesia Stock Exchange. The form of this research is causality associative research. The research data uses secondary data published by the sample companies. Based on the established criteria, 29 companies representing the consumer goods sector were screened. The results showed that the variables of capital structure, asset productivity, and operating activities can mediate the relationship between investment decisions and funding decisions on firm value.

Published: April 2022

Spasticity is a frequent symptom in people with Multiple Sclerosis. Whilst many respond to first-line therapies it is estimated that 30-40% will have suboptimal treatment response requiring more specialised management. Such strategies include combination of oral medications, botulinum toxin, nabiximols and consideration of intrathecal therapies; baclofen or phenol. Early expert intervention as outlined in this review can have a positive impact on functional ability and quality of life for people with MS.
Cerebral malaria and the story of Quinine and the Fever Trees
Authors:   Hull Royal Infirmary, Hull, UK, Pearce JMS
Published: April 2022

Cinchona bark was first recorded as a cure for malaria by the Spanish in Peru around 1630. A Spanish missionary allegedly learned of the treatment from the Indian natives. Cerebral malaria caused by Plasmodium falciparum is life threatening and one of the commonest encephalopathies in the world. Quinine was the first effective treatment, discovered in the bark of quina-quina, cinchona, ‘the fever tree’ in Peru in 1633. Many tales – many fanciful – relate to its early use. Foremost of the discoverers in 1735 was a group of French scientists in an expedition to Peru directed by the Parisian Academie Royale des Sciences. It was then widely exported and employed in Spain, Italy and Britain to become the standard treatment.
A IMPLICAÇÕES DA TOXINA BOTULÍNICA: ALTERAÇÕES FACIAIS COMO FENÔMENO ESTÉTICO ENTRE JOVENS MENORES DE 25 ANOS DE IDADE

A Toxina Botulínica A (TBA) é uma substância que vem sendo muito utilizada como alternativa para tratamento de algumas patologias e prevenção de rugas. O presente estudo intentou analisar a transição do uso da (TBA), para o público mais jovem. Trata-se de uma revisão integrativa de abordagem qualitativa de natureza descritiva, realizada em livros e bancos de dados Scielo, Google Acadêmico, Lilacs e Pubmed, Pepsic. A TBA deixou de ser associada ao aparecimento das linhas e rugas e agora é aplicada antes mesmo desses primeiros sinais do envelhecimento. O consumo exagerado entre jovens menores de 25 anos, tem aumentado, permeado da autocrítica e medo do envelhecimento. O botox preventivo virou um trend no mundo da beleza. O consumo exagerado entre jovens menores de 25 anos, nos leva ao encontro de outro problema que é a frequência de pacientes jovens com o Transtorno Dismórfico Corporal (TDC) nos atendimentos relacionados à estética principalmente facial. Embora este estudo tenha apontado pontos positivos do uso da TBA, não se pode negar a real necessidade de se conhecer mais detalhadamente o perfil do paciente, evitando o incentivo a sua obsessão com o corpo.

Objectives. Internal Medicine physician trainees faced unique challenges as the primary frontline physicians at a tertiary COVID-19 government referral center during the COVID-19 pandemic. This study examined the prevalence of burnout and resilience of these physician trainees during the early period of the pandemic, the determinants of burnout, and their sources of anxiety and coping mechanisms.

Methods. Using a mixed-methods approach, we conducted an online cross-sectional survey to measure burnout and resilience among 196 Internal Medicine physician trainees using the Maslach Burnout Index Human Services Survey for Medical Personnel and the Connor-Davidson Resiliency questionnaires, respectively. We then conducted virtual focus group discussions and in-depth key informant interviews to explore the trainees’ sources of anxiety and coping mechanisms until thematic saturation was satisfied.

Results. Out of 146 respondents (from 196 eligible participants, 74% response rate), four percent of physician trainees fit the frank burnout profile, 40% were engaged, while the majority had intermediate profiles (23% ineffective, 28% overextended, and 4% disengaged). The mean resilience score was 72.9 (SD 12.4). Resilience was a significant negative predictor for burnout (Beta Coefficient = -0.73, p<0.001). Its protective effect decreases in those with more exposure to patient deaths (Beta Coefficient = 6.767, p<0.05). Significant sources of anxiety included changes in the practice of medicine (changes in workflow, working in full personal protective equipment, telemedicine and zoom fatigue, constant threat of acquiring the infection) and having competing demands between service and training. Coping mechanisms included preserving a haven, maintaining social relationships, and self-care.

Conclusion. In the largest government hospital in the Philippines, four percent of Internal Medicine physician trainees had burnout, 40% were engaged, and the majority were at-risk for burnout a few months into the COVID-19 pandemic in 2020. Resilience reduces the risk for burnout. However, its protective effect decreased with exposure to a higher number of patient deaths per week.
