A modified simplex embedding method for solving convex optimization problems with a large amount of constraints
Authors: Колосницын А.В.
Published: August 2021

Рассматривается метод симплексных погружений, адаптированный для решения задач выпуклой оптимизации с большим числом ограничений. Разработаны две модификации, позволяющие ускорять работу метода. Первая из них использует более экономичный способ расчета невязок ограничений, что позволяет существенно сокращать время работы алгоритма в случае большой размерности задачи. Вторая модификация основана на возможности метода определять неактивные ограничения задачи. Представлены результаты вычислительных экспериментов с использованием модифицированных версий метода симплексных погружений при решении тестовых задач квадратичной и выпуклой недифференцируемой оптимизации.

A simplex embedding method adapted for solving convex optimization problems with a large amount of constraints is considered. Two modifications of the method are proposed for better performance. First of them uses a more economical approach to the residual computation for constraints, which allows one to significantly reduce the execution time of the algorithm in the case of a large amount of constraints. One of the important peculiarities of the simplex embedding method is its ability to find inactive constraints. This property of the method is used as the basis for its second modification. The numerical results obtained when solving a number of quadratic and convex nondifferentiable optimization problems show the efficiency of the proposed modifications.

Authors: Феськов С.В. , Хохлова С.С.
Published: August 2021

Предложены подходы к численному решению систем уравнений, описывающих кинетику двухстадийной фотохимической реакции в вязком полярном растворителе. Математическая модель построена на основе расширенной интегральной теории встреч и учитывает диффузионную подвижность молекул-реагентов в жидкости, неравновесность среды и внутримолекулярных степеней свободы, удаленный перенос электрона в донорно-акцепторных парах, разделенных растворителем. В рамках метода броуновского моделирования разработаны алгоритмы расчета безреакционных стохастических траекторий частиц на поверхностях свободной энергии, соответствующих различным состояниям реагентов и продуктов, схемы детектирования реакционных событий и генерации электронных прыжков, а также алгоритмы расчета нестационарных потоков частиц между электронными состояниями и вычисления интегральных ядер кинетических уравнений. Представлены результаты тестовых расчетов, демонстрирующие корректность численного решения и воспроизводящие известные особенности реакций электронного переноса в полярных жидкостях.

Efficient approaches to the numerical solution of equations describing the kinetics of two-stage photochemical reactions in a viscous polar solvent are proposed. The mathematical model is based on the extended integral encounter theory and takes into account diffusive mobility of reactants in solution, nonequilibrium of solvent and intramolecular degrees of freedom, and remote electron transfer in solvent-separated donor-acceptor pairs. In the framework of the Brownian simulation technique, a number of numerical algorithms for calculating unreactive stochastic trajectories of particles on free energy surfaces corresponding to different electronic states of reactants and products are suggested, some computational schemes for the detection of reaction events and the generation of electronic hops are developed, and algorithms for calculating the time-dependent reaction fluxes between the electronic states and integral kernels of the kinetic equations are implemented. The results of test simulations demonstrating the validity of the numerical solutions and reproducing well-known features of electron transfer reactions in polar solvents are discussed.

Рассматривается задача упаковки шаров двух типов в замкнутое ограниченное множество в трехмерном пространстве как с евклидовой, так и со специальной неевклидовой метрикой. Требуется максимизировать радиус шаров при известном количестве шаров каждого типа и заданном отношении между радиусами. Предложен вычислительный алгоритм, основанный на комбинации метода бильярдного моделирования и оптико-геометрического подхода, базирующегося на фундаментальных физических принципах Ферма и Гюйгенса. Приведены результаты вычислительного эксперимента.

The problem of packing balls of two types into a closed bounded set in three-dimensional space with the Euclidean metric and a special non-Euclidean metric. It is required to maximize the radius of the balls for a given number of balls of each type and a known ratio of radii. We propose a computational algorithm based on a combination of the billiard modeling method and the optical-geometric approach employing the fundamental physical principles of Fermat and Huygens. The results of numerical experiments are discussed.
Allocation of three brightness levels on a noisy image
Authors: Лихачев А.В.
Published: August 2021

Предложен новый метод восстановления изображений, имеющих три неизвестные градации яркости. Для их определения используются фрагменты изображения, гистограммы которых согласуются с заданным распределением шума. Далее все пиксели распределяются по найденным уровням яркости посредством бинарной классификации. Выполнен вычислительный эксперимент, по результатам которого оказалось, что ошибка оценки исходных яркостей не превысила 3%. При относительно низком уровне шума доля неверно классифицированных пикселей от их общего числа составила менее 0.006.

A new recovery method for images with three unknown brightness levels is proposed. In order to determine these levels, we use the image fragments whose histograms correspond to a given noise distribution. All pixels are distributed over the found brightness levels by a binary classification. The numerical results show the error in the estimate of the original brightnesses is no more than 3%. When the noise level is relatively low, the fraction of wrong classified pixels in their total amount is less than 0.006.

Authors: Beraldo Rossana Mary Fujarra
Published: August 2021

Este estudo enfocou a apropriação de tecnologias digitais por duas professoras como instrumento de ensino e instrução em escola de ensino médio. Temos interesse na trajetória docente na transição de práticas tradicionais para contextos híbridos de aprendizagem. Utilizamos métodos mistos a partir da Grounded Theory e aporte da Teoria da Atividade e abordagem dialógica. Optamos pela pesquisa qualitativa com entrevista em áudio, fonte documental e observações de interações entre estudantes em contexto híbrido de aprendizagem. Os resultados indicaram que a trajetória docente perpassa pela apropriação tecnológica na: a) convencionalização de um campo simbólico e semiótico no qual as práticas mediadas por recursos digitais passam pela generalização do objeto na/pela atividade coletiva; b) integração dos instrumentos digitais como um corpo de conhecimentos que podem ser aplicados em tarefas situadas e orientadas para metas.
Las narrativas autobiográficas en la construcción de la experiencia y el sí mismo
Authors: González María Fernanda
Published: August 2021

El articulo ofrece una explicación semiótica y psicogenética sobre cómo las narrativas autobiográficas organizan las experiencias  y dan un sentido de continuidad al yo. Las narrativas son actuaciones comunicativas que se articulan en dos direcciones complementarias. Por un lado participan en la interpretación y construcción de significados sobre una situación y por el otro dan sentido a la propia actuación. Desde ese punto de vista puede comprenderse cómo se construye ”“ de modo mediado y dialógico-  la identidad narrativa, lo que lleva a la apreciación ética y estética de las actuaciones propias y del sí mismo.
Sentidos y potencialidades del registro (auto)etnográfico en la investigación biográfico- narrativa
Authors: Aguirre Jonathan , Porta Luis
Published: August 2021

Este artículo aborda los sentidos y las potencialidades epistémico-metodológicas que asume el registro autoetnográfico en la investigación biográfico-narrativa a partir de los relatos hilvanados por parte del investigador social en el transcurrir del trabajo de campo de una investigación cualitativa sobre políticas públicas de formación docente. Mediante la utilización del registro autoetnográfico, se evidencia que la autoetnografía narrativa a la vez que posibilita, reconstruir la experiencia de los sujetos investigados mediante de sus propios relatos, implica emocionalmente al investigador social desde sus propias sensibilidades y subjetivaciones, objetivándolas y validándolas en el proceso de interpretación de los datos recopilados en la investigación.

A avaliação formativa do desempenho do ensino
Authors: Wiliam Dylan
Published: August 2021

A argumentação deste artigo se baseia em quatro propostas. Em primeiro lugar, fazem-se necessários maiores realizações educacionais tanto para os indivíduos quanto para a sociedade. Em segundo lugar, para conseguir maiores realizações educacionais se requer maior qualidade nos professores. Em terceiro lugar, uma maior qualidade nos professores demanda investir nos professores que já se encontram trabalhando em nossas escolas. Em quarto lugar, esse investimento precisa tomar um formato radicalmente distinto do desenvolvimento profissional que comumente os professores receberam.
Coreografías didácticas institucionales y calidad de la enseñanza
Authors: Beraza Miguel A. Zabalza , Cerdeiriña María Ainhoa Zabalza
Published: August 2021

Enseñar es “the intencional arrangement of situations in which apropiate learning will occur” (Menges,1997). Partiendo de ese principio, muchas de las miradas y de las prácticas educativas han ido cambiando el foco, trasladando el protagonismo de lo que el docente decía o hacía a lo que los estudiantes hacen en ambientes de aprendizaje especialmente preparados para enriquecer su experiencia y orientar su aprendizaje. Las coreografías, metáfora tomada del mundo de la danza (Oser y Baeriswyl, 2001) forman parte de esas nuevas miradas sobre la enseñanza. Con una arquitectura simple, las coreografías contienen 4 componentes básicos: anticipación, coreografía externa, coreografía interna y producto. El presente artículo trata de situar el concepto de coreografía en el contexto de estas nuevas miradas sobre la docencia universitaria y se centra, sobre todo, en las coreografías institucionales, sobre las que se presenta un modelo de análisis basado en 9 variables: las tres básicas de toda docencia (docente, estudiante, contenidos); otras tres referidas a las características de organización interna de los tres elementos básicos de la docencia mencionados (relaciones entre los docentes; relaciones entre los estudiantes; relaciones entre los contenidos); y, finalmente, otras tres variables referidas a la relación de cada uno de esos elementos con los otros dos: relaciones entre profesores y estudiantes; relaciones entre estudiantes y contenidos; relaciones entre profesores y contenido.

Authors: BALCI Senay , GEZGİN ULAS Gamze , GORUR Aysegul , ÇELİKCAN Havva Didem , BAYAZIT Ayşe Gül , SUCU Nehir , TAMER Lülüfer
Published: August 2021

Amaç: Akut ekstremite iskemisi, emboli ya da tromboz akabinde ortaya çıkmakta ve tedavi edilmezse ekstremite kaybı ve hatta ölümle sonuçlanabilmektedir. Ayrıca, tanının gecikmesi acil girişim şansını ortadan kaldırmaktadır. Bu nedenle, erken tanı büyük önem taşımaktadır. Miyokard enfarktüsü, serebral infarkt ve pulmoner infarkt gibi akut iskemik durumlarda düzeylerinin yükseldiği bildirilen iskemi modifiye albüminin, iskemik durumlarda tanı belirteci olabileceği bildirilmektedir. Bu çalışmanın amacı da alt ekstremite iskemisinde iskemi modifiye albüm düzeyini belirlemek ve erken tanıya yardımcı bir parametre olarak kullanılabilirliğini araştırmaktır. Yöntem: Bu çalışmaya alt ekstremite iskemisi olan 5’i kadın, 19’u erkekten oluşan 24 hasta (hasta grubu; 23-89 yaş) ve kontrol amaçlı gelen 19’u kadın, 15’i erkekten oluşan 34 sağlıklı gönüllü (kontrol gurubu; 20-75 yaş) olmak üzere 58 kişi dahil edildi. Dahil edilme kriterlerine uygun hasta ve kontrol gruplarındaki bireylerden elde edilen serum örneklerindeki iskemi modifiye albüm düzeyleri, ELİSA kiti (Organo Teknika, Avusturya) ile analiz edildi. Gruplar arası iskemi modifiye albüm düzeylerinin karşılaştırılmasında Mann Whitney U testi kullanıldı. Bulgular: Akut ekstremite iskemisi olan hastalarda, kontrol grubundakiler ile karşılaştırıldığında önemli ölçüde artmış iskemi modifiye albüm düzeyi olduğu tespit edildi (p <0.001). ROC eğrisi analizinde sensitivite değeri 91.7 ve spesifite değeri 82.4 olarak tespit edildi. Sonuç: Alt ekstremite iskemisinde serum iskemi modifiye albüm düzeylerinde görülen önemli artışın, ekstremite iskemisinin tanısında yararlı olabileceğini düşünmekteyiz.
Sınırlı evre küçük hücreli akciğer kanseri tanılı hastalarda eşzamanlı kemoradyoterapi öncesi sistemik immün inflamasyon indeksi’nin sağ kalıma etkisi
Authors: KÜÇÜK Ahmet , ESKİCİ ÖZTEP Şükran , YILMAZ Eda Bengi , TOPKAN Erkan
Published: August 2021

Amaç: Birçok çalışmada, nötrofil (N), trombosit (T) ve lenfosit (L) bazlı sistemik immün inflamasyon indeksinin (Sİİ) çeşitli solid tümör tiplerin de sağ kalım sonuçlarını öngörebildiği gösterilmiştir. Daha önce sadece SE-KHAK hastalarından oluşan gruplarda eşzamanlı kemoradyoterapi (E-KRT) öncesi Sİİ’nin prognostik önemini araştıran çalışma olmaması nedeniyle Sİİ’nin bu hasta grubundaki prognostik önemini araştırmayı amaçladık. Yöntem: Ocak 2007-Aralık 2018 tarihleri arasında iki radyasyon onkolojisi merkezinde E-KRT ile tedavi edilen SE-KHAK hastalarını içeren retrospektif veriler analiz edilmiştir. Sİİ değerleri E-KRT'nin başlamasından önceki 7 gün içerisinde elde edilen toplam 139 hastanın periferik kan örneklerinde Sİİ = N×T/L formülü kullanılarak hesaplandı. Çalışma popülasyonunu farklı genel sağ kalım (GS) sonuçlarına sahip iki gruba ayırabilecek tedavi öncesi Sİİ’nin optimal eşik değeri receiver operating characteristic (ROC) analizi ile değerlendirildi. Genel sağ kalım (GS) Kaplan-Meier eğrileri kullanılarak bulunmuştur. Birincil sonlanım noktası Sİİ değeri ve GS sonuçları arasındaki ilişkiydi. Bulgular: Tedavi öncesi Sİİ’nin optimal eşik değeri 524 olarak bulunan hastalar iki gruba ayrılmıştır [Eğri altındaki alan (AAA): %68.1; duyarlılık: %68.6; özgüllük: %66.4]: Grup 1: Sİİ<524 (N=65) ve Grup 2: Sİİ≥524 (N=74). İki Sİİ grubu arasındaki Kaplan-Meier karşılaştırmaları Sİİ <524 grubunda Sİİ ≥524’ten anlamlı düzeyde daha uzun GS olduğunu (sırasıyla 34.6’ya karşı 12.5 ay; p<0.001) gösterdi. Benzer şekilde, 5- (%32'ye karşılık %8.9) ve 8 yıllık (%15'e karşılık %6) GS oranları da Sİİ<524 grubunda daha iyiydi. Çok değişkenli analizler sonucunda Sİİ’nin GS (p <0.001) için bağımsız bir prognostik faktör olduğu görülmüştür. Sonuç: Bu retrospektif analiz sonuçları tedavi öncesi Sİİ’nin, E-KRT ile tedavi edilen SE-KHAK hastaları için güçlü ve bağımsız bir prognostik biyobelirteç olduğunu göstermiştir.

Amaç: Temporomandibular eklem (TME) bozukluklarının etiyolojisi çok faktörlüdür ve bu etiyolojiden sorumlu olan faktörlerin rolü hala tartışmalıdır. Bu çalışmanın amacı, temporomandibular bozukluğu (TMB) hastalarının sosyo-demografik ve klinik özelliklerini incelemektir. Yöntem: Çalışma, bir diş hekimliği fakültesinin ağız, diş ve çene cerrahisi kliniğinde tedavi arayan 508 TMB hasta üzerinde gerçekleştirildi. Hastalar sosyo-demografik özellikler, etiyolojik risk faktörleri ve klinik muayene bulguları açısından değerlendirildi. Bulgular: Çalışmaya katılan hastaların çoğu (%83.5) kadın idi ve en büyük yaş grubunu 18-25 yaşındakiler oluşturdu. İşsizler, ev hanımları ve öğrenciler arasında TMB daha yaygın idi. Hastaların yaklaşık dörtte üçünde (%75.6) bruksizm ve %14.2’sinde bruksizm dışında bir parafonksiyonel alışkanlık var idi. Hastalarda en sık görülen üç hastalık sırasıyla psikiyatrik bozukluklar, peptik ülser ve troid hastalıkları idi. Hastaların yaklaşık dörtte biri (%24.4) TMB dışında bir kas-iskelet sistemi hastalığı olduğunu ve %11.8’i geçmişte bir TME travması yaşadığını bildirdi. Hastaların %40.9’unun vücut kitle indeksi normalin üzerindeydi ve %77.2’si düzenli egzersiz ve spor yapmadıklarını bildirdi. Hastaların yarıya yakınında (%45.7) çift taraflı TMB şikayeti vardı ve %32.3’ünde şikayet süresi 5 yıl ve daha fazla idi. Hastalarda %70.1 oranı ile baş ağrısı en sık görülen ek semptomdu, bunu kulak çınlaması (%46.5) ve boyun ağrısı (%45.7) izledi. Hastaların klinik muayenesinde %43.3’ünde palpasyonda şiddetli ağrı, %71.7’sinde klik, %30.7’sinde krepitasyon ve %59.8’inde alt çenesinde deviasyon vardı. Hastaların %50.4’ünün maksimum ağız açıklığı 35mm ve altında iken, % 3,9’u ileri derecede kısıtlanmış ağız açıklığına (20mm ve daha az) sahip idi. Sonuç: Bu kesitsel çalışma bulguları TMB etyolojisinin karmaşık ve çok faktörlü olduğu tezini doğrulamaktadır. TMB etyolojisini açıklamaya yönelik neden-sonuç ilişkisini ortaya koyan uzun soluklu çalışmalar yapılmalıdır.

Mathematical model of agricultural crop yield
Authors: Likhatsevich A. P.
Published: August 2021

Theoretical basis for presenting research results in agricultural science is mathematical statistics and probability theory using empirical forms of generalization of experimental data. To improve the methods of planning field experiment and processing its data using digital technologies, we proposed to use mathematical modeling based on physical principle of balance of cause-and-effect interactions in a closed physical system as a priority option. When analyzing impact of environmental factors on crop yields, the initial provisions, the mathematical modeling of the crop yield is based, on are not associated with characteristics of crops and natural conditions, therefore, the model options are universal in application and are valid for any agricultural crop, regardless of the region of cultivation. To ensure statistically correct digital information, based on the established forms of mathematical model, the field experiment layout aimed at establishing the dependence of the crop yield on yield-forming factors should include at least 4 options for nutritional levels (NPK) with a research duration of at least 4 years. To check the accuracy of the developed crop yield model, the data of independent field experiments of Professor N.N. Semenenko with barley and winter triticale has been used. It has been determined that, in Belarus, yield-forming factors, as a result of their impact on the grain yield, are arranged in the following decreasing sequence: total dose of applied NPK º the amount of precipitation during the active phases of growing season → air temperature for the same period. Calculations have shown that decrease in the number of yield-forming factors taken into account in the mathematical model from three (food, moisture and heat) to two (food and moisture) reduces the accuracy of calculating the grain crop yield insignificantly.
State information system “AITS”: features of formation and directions of development
Authors: Bryula I. V.
Published: August 2021

Animal breeding is a strategic branch of agri-business in the Republic of Belarus, focused on solving social and economic issues and ensuring national food security. Currently, its development is innovations based, forming a high level of the country’s production and export potential. In the world ranking by the end of 2020, the Republic of Belarus took the 5th place in terms of milk exports (4.8 million tons). As world experience shows, the key direction is implementation of electronic identification of animals as an accounting system in agriculture, including assigning identification number to an animal by tagging, registering information about it in a database and issuing an appropriate passport. The paper summarizes and systematizes legal, organizational and financial conditions for creation and functioning of national information systems in Australia, Argentina, Brazil, Great Britain, the European Union, Canada, the Netherlands, the USA, Switzerland, and Japan. It has been determined that absence of a system for identifying the registration of farm animals leads to distortion of data on the number of livestock, and also creates obstacles for selection work and livestock breeding, decreases efficiency of antiepizootic measures, and inhibits international trade in animals and animal products.

First monument of stone architecture in Belarus, created in the Romanesque building tradition
Authors: Trusov O. A.
Published: August 2021

The article for the ﬁrst time proposed a new version of the origin of masters who were invited to build the Minsk temple. The article says that the masters could be invited from Germany (Saxony), and not from Poland, as previously thought.

In 1949–1951 the archaeologist Vasil Tarasenka found the ruins of an unﬁnished temple on the territory of Minsk Castle (later this monument was studied by E. Zagarulsky, G. Shtykhaŭ and A. Miadzvedzeŭ). The foundation and lower parts of the walls of the temple are made of stone and are squared with stone tiles of a rectangular shape on a mortar. The masonry technique is Romanesque, characteristic of Western European architecture.

The main controversy is the time of construction of the temple. Some researchers believe that this is the second half of the XI century, others believe that the ﬁrst Minsk appanage prince Gleb began the construction at the beginning of the XII century.

Based on Romanesque construction methods, it is believed that Polish craftsmen built the temple. The author for the ﬁrst time expresses and justiﬁes the German (Saxon) origin of the builders of the temple in Minsk.
Problem of language interference in literature and its impact on speech сommu nication
Authors: Patapava N. L.
Published: August 2021

The article highlights the evolution of linguistic views on the phenomenon of interference. The problems of interference have been worrying a large number of scientists both in our country and abroad for several decades since the last century. The research in the ﬁeld of language systems interference continues in all directions nowadays. However, a number of its aspects remain poorly understood. The relevance of the language interference study is connected with the emergence and study of new concepts, such as linguistic interference, as well as translation, textual, sociocultural, cross-cultural, terminological interference.

Having studied the views of the scientists on the problem of language interference in this article, we can conclude that bilingualism and language contact are necessary conditions for the manifestation of interference. The place of manifestation of linguistic interference is the person himself, communicating in a foreign language or translating from one language to the other when he is trying to compensate for some elements, phenomena and functions of one language system with elements, phenomena and functions from the other one, which can lead to accent, literalism, distortion of meaning and to various deviations from the original, but also in some cases can help with communication or translation.

The need to study, systematize and develop the recommendations for overcoming and using the phenomenon of interference in a professionally oriented translation is not in doubt. At present, the internationalization of higher education is of fundamental importance. Personal experience in the process of studying and teaching foreign languages shows that the phenomenon of interference must be approached consciously: interference must be studied and understood in detail in order to subsequently know how to prevent it or use it constructively in a professionally oriented translation.

The purpose of this study is to analyze the factors that influence the intention to use of digital wallets with an expanded approach of technology acceptance model by adding subjective norms and perceived security as exogenous variables. Subjective norms variable is hypothesized either directly or indirectly through the endogenous variables in TAM to influence intention to use, while perceived security variable is hypothesized to have a direct effect. The hypotheses that have been submitted forms a theoretical framework as structural equation model (SEM). Empirical data was collected through an online survey of 233 respondents who answered 23 questionnaire questions in full. The selection of respondents is determined by purposive—non-probability sampling approach from active users of LinkAja in Bandung whose population is not yet known. The software used to perform the statistical tests of informing that all indicators used meet the criteria of validity and reliability, the ten hypotheses submitted are all accepted based on the t-significance test and strong determining factor. The five TAM variables and their expansion have a positive and significant effect on the intention to use. The biggest influence of antecedent variables on the intention to use sequentially is subjective norms, perceived usefulness, attitude, perceived ease of use, and the smallest is perceived security. In increasing the intention to use, operators should prioritize on increasing subjective norms from prospective users, such as testimonials from role models about the ease of use, convenience, and attractiveness of the digital wallets.

The effects of crude aqueous extract of Ehretia anacua on alloxan induced diabetic rats was investigated. Male albino rats of weighing between 120 to 150 were used, divided into 6 groups of five animals per group. Group I received distilled water throughout of the experiment and served as the control. Group II received 110 mg/kg of alloxan interperitoneally. Groups III, IV, V and VI received 110 mg/kg of alloxan and in addition administered with aqueous Ehretia anacua extract daily for 14 days. Blood glucose level was monitored at five days interval for fourteen days. Target organs (pancrease) was taken from each rat. The histopathological studies of the pancrease were examined. In alloxan - induced diabetic rats, blood glucose level was significantly increased compared with the control rats. Treating diabetic rats with 50, 100 and 200 mg/kg bw Ehretia anacua caused a significant decrease in the blood glucose level. The Photomicrograph of the histopathology examination of the pancrease (× 100) of the groups treated with alloxan showed poor architecture was destroyed whereas those treated with Ehretia nancua showed normal architecture. This illustrates the amelliorative effects of the extract on the alloxan-induced tocicity. It could be concluded from these results that, Ehretia nancua extract should be used in manufacture processes of the natural products as functional foods or as a dietary supplement with anti-diabecretic activity as hypoglycemic effect.

Ausgehend von kolonialistisch geprägten psychologischen Blickweisen auf die vermeintliche Natur der Kolonialisierten geht der Artikel der Frage nach, was unter dem Geist des Kolonialismus verstanden werden kann, wie er auch in die Psychologie eingegangen und wie er darin immer noch wirksam ist. Es wird dann das Potenzial der Postkolonialen Studien aufgezeigt, die gegenwärtige Psychologie aus ihrem ahistorischen Schlummer zu wecken und sie dazu anzuregen, sich sowohl theoretisch als auch praktisch mit der Entstehung von psychischen Belastungen und Verletzungen zu befassen, in die sie selbst involviert war und involviert ist.

Published: August 2021

The pandemic novel coronavirus disease 2019 (Covid-19) has a high death rate, which threatens nearly most of the world's population. The main reason for mortality in severe acute respiratory syndrome is intensified inflammatory activity followed by oxidative stress and inflammatory reactions in the lungs. To date, this pathology does not have a clear and conclusive cure, troubling the world population, particularly elderly adults, who are the major risk group. In this sense, assessing the effectiveness of current pharmacological agents, which can be used to resolve or attenuate this pulmonary complication's seriousness that has threatened the lives of so many people globally, is of particular importance. In contrast to quarantine, public health interventions are urgently needed to reduce the risk of illness and death. Evidence reveals that vitamin D supplementation may be possible in treating Covid-19. Additionally, numerous trials and studies have started to study the effect of vitamin D supplementation on patients with SARS-CoV-2 infection.
