Authors: Czapliński Paweł
Published: February 2021

The article attempts to assess the impact of the strategy for industrial companies on the spatial structure of Pomeranian industry. Strategies are analyzed on the level of labour resources, production and location decisions. In order to avoid formal difficulties and testing of new methodological solutions, the selected strategies were characterized on the basis of the metaphorical approach. Surveys conducted among industrial companies of the Pomorskie voivodship, using the above-mentioned method, tend to the general conclusion that the forms of behaviour in the tested businesses regardless of their volatility, have an influence on the spatial structure of Pomeranian industry, however its scale, scope and direction have not yet been fully identified.

Choice of Locations by Foreign Investors: Motives for and Factors of Starting a Manufacturing Activity (the Example of Selected Factories in Poland)
Authors: Tobolska Anna
Published: February 2021

The choice of a location is one of the most important decisions taken by an enterprise, both at start-up and at other stages of its life cycle involving a relocation of activity or a spatial fragmentation of the chain of value-added generation. The choice of a location by an enterprise is also of great significance for the development of the region selected, its economic and social structure, and the pattern of its spatial links. That is what makes the choice of a location one of major research problems in socio-economic geography, and in particular in its sub-discipline – industrial geography, with its scope of research embracing issues in location theory and factors of the location of enterprises and industrial plants.This paper offers an analysis of the location factors of selected factories – affiliates of international corporations, in terms of their strategic decisions of expansion onto markets abroad in the form of foreign direct investment (FDI). For international corporations, the choice of a new place of economic activity is closely connected with global advantages of conducting business at the international scale and with motives for their internationalisation.

Authors: Ayas Serhat
Published: February 2021

There are very few studies on cabbage at different fertigation levels in the Marmara Region, where this study was conducted. In this respect, our study has a unique quality. This study was carried out in Bursa Uludag University Yenisehir İbrahim Orhan Vocational School application greenhouses in 2014-2015 years. Five different irrigation treatments (T1: 100% (full irrigation), T2: 75%, T3: 50%, T4: 25%, T5: 0% (non-irrigated)) and two different fertigation treatments; F1.0: 100% (100:100:100 NPK) fertigation and F0.5: 50% (50:50:50 NPK) fertigation were combined together to determine the effects on yield and quality parameters of potatoes. The amount of irrigation water in 2014 and 2015 years varied between 0.0-630.0 mm and 0.0-660 mm, respectively, while evapotranspiration values varied between 180.0-670 mm and 190.0-675 mm, respectively. It was determined that irrigation water and fertigation levels, yield and quality parameters of potatoes were affected significantly. In both application years, the highest yield was obtained from T1F1.0 treatment as 45.0 and 47.0 tons‘ ha-1 respectively, while the lowest yield was obtained from T5F1.0 treatment as 4.0 and 5.0 tons ha-1, respectively. In 2014 and 2015 years the crop response factor (ky) values of potato were calculated as 1.11-1.11 and 1.21-1.14, respectively. When the full fertigation (F1.0: 100% -100:100:100 NPK) and the insufficient F0.5: 50% - (50:50:50 NPK) fertigation treatments are compared, significant differences have arisen in terms of yield and quality parameters. T2F1.0 and T2F0.5 treatments can be recommended as the most effective irrigation and fertilization levels of potato.

CORPORATE SOCIAL RESPONSIBILITY, CORPORATE REPUTATION, AND SHARE PRICE: A STUDY OF CONSUMER GOODS INDUSTRIES USING SUSTAINABLE ACCOUNTING STANDARD BOARD (SASB) DISCLOSURES
Authors: Gunawan Juniati , Susilo Hermawan
Published: February 2021

This study aims to seek theㅤinfluenceㅤof corporateㅤsocialㅤresponsibilityㅤdisclosures (CSRD) on share prices with the company's reputation as intervening variable. The samples are derived from all of the consumer goods industries, which areㅤlistedㅤonㅤIndonesiaㅤStockㅤExchange during 2014-2018. Content analysis method is used to measure the company’s corporate social responsibility disclosures based on company’s annual reports and/or sustainability reports. Unlike previous studies, this research applies the Sustainability Accounting Standard Board (SASB) as the disclosures list to award the scores. Panel regression method and Eviews 9 were applied as analytical tools. Findings shows that CSRD does not influence the corporate reputation, but in contrast, CSRD influence significantly and positively to the share prices, and so does the corporate reputation. However, CSRD does not influence the share prices when it is mediated by the corporate reputation as intervening variable. When CSRD and Reputation were examined together, controlled by ROA, these variables positive significantly influence the corporate share price.
Neural Network Approach to Crater Detection for Lunar Terrain Relative Navigation
Authors: Downes Lena M. , Steiner Ted J. , How Jonathan P.
Published: February 2021

Terrain relative navigation can improve the precision of a spacecraft’s state estimate by providing supplementary measurements to correct for drift in an inertial measurement unit. This paper presents a crater detector, LunaNet, that uses a convolutional neural network (CNN) and image processing methods to detect craters from camera imagery taken by a spacecraft’s onboard camera. These detections are matched with known lunar craters, and these matches are used as visual landmark measurements in an extended Kalman filter (EKF). Our results show that, on average, LunaNet detects approximately twice the number of craters in an intensity image as two prior intensity-image-based crater detectors, and detects more accurate craters than the other two detectors as well. One of the challenges of using cameras for this task is that they can generate imagery with significant variations in image quality and noise levels. LunaNet is robust to four common types of image noise due to its incorporation of a CNN that is trained on diverse data. LunaNet also produces crater detections with better image persistence over a trajectory. These qualities contribute to a LunaNet-based EKF that results in consistently lower state estimation error and that outperforms the filters based on the other detectors.
SIMPLIFICATION AND VERIFICATION OF DYNAMIC EQUATIONS OF MOVEMENT OF AN AUTONOMUS UNDERWATER VEHICLE
Authors: Varga Martin
Published: February 2021

Urgency of the research. Currently, most machines go through computer modelling and simulation phase in their development cycle. The ability to formulate simple yet effective models helps to both decrease development cost and time. Target setting. Today many tasks are being accomplished by robots whether mobile robots or industrial robots. To simulate the behaviour of these robots a dynamic model is needed. These models can be very complex and the parameters to fill all the equations can be difficult to find, therefore simplifications need to be implemented and verified so that the models are still accurate. Actual scientific researches and issues analysis. A basic step in the development of new products is the simulation and modeling phase. Development of a computer model prior to development of a physical prototype saves time and resources.
Unfortunately, some models can be very complex and require parameters only acquirable from tests on physical systems. That is why often these models need to be heavily simplified which can lead to imprecise results. Often, verification of the
model is needed. One of such systems is the dynamic model of an Autonomous underwater vehicle (AUV). Uninvestigated parts of general matters defining. This article focuses on verification of a highly simplified dynamic simulation model of AUV.
The research objective. The aim of these research was to model a simplified dynamic model of an AUV moving through fluid with nonnegligible viscous properties and verifie the model by comparing simulation results with experimental results obtained by testing on the real AUV. The statement of basic materials. The analysis consists of an attempt to summarise the possible ways to simplify a general dynamic equation for movement of an AUV in a fluid with nonnegligible viscous properties and showing, that even such simplified model stays usable and bring with it reduction in complexity. Conclusions. This article shows the basic dynamic equations for describing the movement of a general AUV in a fluid with nonnegligible viscous properties and the possible simplification of this equation in regard to a specific construction of a real world AUV. The results gathered from the simulation model are then compared to experimental results performed on the physical AUV with the conclusion, that both datasets are matching within reasonable margins. This article serves as a good reminder of the importance and benefits of well establishing simplifications in a model of a real-life system.
SNAKE-LIKE ROBOT RECTILINEAR MOTION ANALYSIS
Authors: Alexander Gmiterko
Published: February 2021

Urgency of the research. Some animal locomotion mechanisms are often used for robot designing because of their appropriate properties for some kinds of environments. A snake has excellent skeletal structure which provides it advantageous properties for reaching places where other kinds of mechanisms cannot move and operate.
Target setting. A biologically snake by mathematically way is described. The properties of N-mass mechanical system by increasing number of masses are changed with the certain regularity which in this paper is determined. Actual scientific researches and issues analysis. Only a few previous decades the researchers and the designers started to copy the animal motion to the mechanisms. The principal motivations of the snake locomotion are the environments where the traditional machines are not applicable due their dimensions or shapes and where the accessories like the wheels or the legs fail.
Uninvestigated parts of general matters defining. The rapid development of robotics and technologies offers large spectrum of a robotic devices use for hard reach areas or man danger zone. Some animal locomotion mechanisms are often use for robot designing because of their appropriate properties for some kinds of environmetns. The research objective. Within this research one of four basic snake gaits is analysed. The statement of basic materials. There exist various kinds of rectilinear motion models, for example models with masses, dampers and springs. In this study we will deal only with the mass model. Conclusions. The paper also deals with the force effects on i-th moving mass of system and based on this the average velocity of the system is derived. In the conclusion the optimal number of masses N is established in order to the average velocity could be maximum.
Fake News, vacina e os tipos de desinformação
Authors: Gomes Cesar Augusto
Published: February 2021

O objetivo central deste estudo é selecionar e analisar textos relacionados à questão das vacinas e de saúde pública que circularam entre janeiro e abril de 2018, época em que o país viveu um surto de febre amarela na Região Sudeste, nos sites de redes sociais digitais, que foram verificados e publicados pelo site Boatos.org. Caracteriza-se como uma análise de natureza qualitativa e usa como metodologia os Sete Tipos de Desinformação (WARDLE e DERAKHSHAN, 2017) para o fim de classificar tais informações e compreender seu processo de construção. Num segundo momento, procura levantar hipóteses para seu processo de disseminação e elenca possíveis soluções para a resolução do fenômeno. No período analisado, foram encontradas no site um total de 07 notícias sobre o tema examinado e a quase totalidade delas foram classificadas como Conteúdo Enganoso (a manipulação / distorção intencional de informações factuais) e Conteúdo Fabricado (conteúdo novo que é 100% não factual, criado para ludibriar prejudicar). Na origem do processo de disseminação estão: (a) motivação financeira: sites ganham dinheiro com cliques em matérias e as fake news viralizam mais do que as notícias factuais; (b) teoria dos Laços Sociais: para Granovetter (1973) as pessoas tomas decisões pelo aval de suas relações de “Laços Fortes”. Sabendo disso, os produtores de informações não factuais investem (I) na produção de textos mais informais e próximos dos leitores e (II) na disseminação da informação pelas mídias sociais apostando nos vínculos afetivos.
Letramento e autoria

Published: February 2021

Em minha proposta de letramento, a relação entre ser alfabetizado e ser letrado não élinear, o que acarreta um giro teórico e metodológico na questão, visto que deixamos deconsiderar indivíduos empíricos que fazem uso da língua escrita, e sim posições de sujeito dentrodo continuum do letramento, o que implica considerar o lado da perda. Refiro-me às práticasorais, que coexistem com a economia escriturística. Defendo a proposta de um continuum, agraduação de um saber sobre a escrita, que seria independente de variáveis tais comoalfabetização, escolaridade e escolarização. Senso assim, não é a língua que é considerada comoparâmetro, mas os discursos que servem de suporte às práticas letradas. Também a dicotomialíngua oral/língua escrita não serve mais, devido à interpenetração. O que está em questão não ése o sujeito é alfabetizado, mas em que medida ele pode ocupar a posição de autor. Mobilizarei osconceitos de dispersão e deriva para descrever o processo de autoria. O sujeito ocupa a posição deautor quando retroage sobre o processo de produção de sentidos, procurando amarrar a dispersãoque está sempre se instalando, devido à equivocidade da língua, e produz aquilo que Lacandenominou de point de capiton, lugares do processo de enunciação onde há indícios de que osujeito efetuou um movimento de retorno ao enunciado, e pode, assim, olhá-lo de outro lugar. Seconsegue cercar a dispersão, o autor, no entanto, não irá nunca evitar a deriva de sentidos,produto da equivocidade da língua. Ao longo da exposição, apresentarei análises de corpora.
Hegelian Hamann: Attempt at Reconstruction
Authors: Streltsov Alexey M.
Published: February 2021

The present article deals with G. W. F. Hegel's review of J. G. Hamann's works, using «Socratic memorabilia», Hamann's debut piece, as a case in point. It is demostrated that along with penetrating analysis and delineation of the main trends of Hamann's thought Hegel views his teaching through the lens of his own philosophical system. This factor significantly affects his interpretation of select theses of Hamann. Reconstruction of Hamannian thought in Hegel’s review presupposes his treatment first and foremost as that of a chain in dialectical development of the German spirit.

Published: February 2021

Analisa-se neste artigo a permanência de concepções como a de “mata ciliar” na legislação ambiental, nas medidas mitigadoras dos impactos ambientais, nas concepções de movimentos ambientalistas e, também, em pressupostos de pesquisas científicas relacionadas a lagos artificias. Essa noção só seria passível de ser aplicada à realidade ambiental pretérita. A represa de Capivara, no rio Paranapanema (PR/SP) e o seu reservatório de aproximadamente 560 km² são utilizados para a demonstração das transformações ambientais que uma barragem provoca na dinâmica natural de um rio. São alterados os tempos biológicos e históricos, as dinâmicas da economia natural do rio, como correnteza, margens e espécies de peixes e animais, constituindo uma máquina orgânica.
A construção discursiva do conceito de “heresia” no contexto da questão religiosa: uma análise a partir do jornal O Apóstolo (1871-1875)
Authors: Silva Ana Rosa Cloclet da , Silva Leonardo Henrique de Souza
Published: February 2021

No Brasil do século XIX, o advento da modernidade política foi marcado por profundas mutações conceituais, que acompanharam as reconfigurações nos nexos entre religião e política, as quais tiveram como etapa crucial os acontecimentos associados à Questão Religiosa (1872-75). Desde então, a Igreja católica caminhou para a separação oficial e abrupta em relação ao Estado e para a conquista de sua identidade institucional, subordinada ao Sumo Pontífice. Na defesa deste projeto, clérigos e leigos ultramontanos fizeram da imprensa católica instrumento eficaz na nomeação de seus inimigos e preservação de sua influência junto à sociedade civil, à medida que diminuía sua participação política direta. Este projeto visa analisar um dos conceitos que, na conjuntura em foco, foi amplamente veiculado pelo discurso ultramontano, assumindo singular importância e capacidade de generalização, ao mesmo tempo em que se revelou profundamente polissêmico. Trata-se do conceito de “heresia”, o qual, na formulação discursiva ultramontana, observou um deslocamento das heresias medievais em direção às tendências associadas à modernidade ocidental, ajudando a modelar o novo sujeito herético, no Brasil da segunda metade do século XIX. A fonte eleita é o jornal ultramontano O Apóstolo, editado na província do Rio de Janeiro entre 1866 e 1901, cuja análise se pauta no instrumental metodológico da História dos Conceitos.

Authors: Neves Victoria Haydée Deusdedith , Mello David Martins da Silva , Vieira Manuela Azevedo , Gomes Ingrid Cristiane Pereira
Published: February 2021

Este artigo buscou analisar o perfil epidemiológico e os fatores de risco mais relevantes relacionados às neoplasias gástricas. O estudo é uma revisão da literatura atual e foram inclusos 18 artigos da plataforma PUBMED, utilizando os seguintes descritores: stomach neoplasms, risk factors, epidemiology. As pesquisas epidemiológicas afirmam que aproximadamente 1 milhão de casos novos sujam a cada ano e colocam esta afecção como a terceira causa de morte por câncer no mundo. Os fatores de risco mais prevalentes foram idade avançada, sexo masculino, infecção por Helicobacter pylori, tabagismo, consumo de alimentos com alto teor de sódio e ingesta de bebidas alcoólicas. Deste modo, conclui-se que as neoplasias gástricas se constituem uma entidade nosológica de epidemiologia alarmante e decorre da interação de múltiplos fatores de risco, sejam eles modificáveis ou relacionados aos hábitos de vida e, por isso, faz-se essencial reconhecê-los, a fim de prevenir, ou ao menos, diagnosticar precocemente tal condição clínica.
Environment-assisted entanglement purification
Authors: Qiu Liang , Liu Zhi , Wang Xin
Published: February 2021

Two qubits in a pure entangled state passing through and interacting with amplitude damping noises will cause the decay of entanglement. Entanglement swapping combined with environment measurement is proposed to purify entanglement of the two-qubit state. Some initial states can be purified into the maximally entangled ones by just using the protocol for one time, in contrast to iteratively using the protocol given in Phys. Rev. A 89, 014303 (2014).
Quantum advice enhances social optimality in three-party conflicting interest games
Authors: Situ Haozhen , Zhang Cai , Yu Fang
Published: February 2021

Quantum pseudo-telepathy games are good examples of explaining the strangeness of quantum mechanics and demonstrating the advantage of quantum resources over classical resources. Most of the quantum pseudo-telepathy games are common interest games, nevertheless conflicting interest games are more widely used to model real world situations. Recently Pappa et al. (Phys. Rev. Lett. 114, 020401, 2015) proposed the first two-party conflicting interest game where quantum advice enhances social optimality. In the present paper we give two new three-party conflicting interest games and show that quantum advice can enhance social optimality in a three-party setting. The first game we propose is based on the famous GHZ game which is a common interest game. The second game we propose is related to the Svetlichny inequality which demonstrates quantum mechanics cannot be explained by the local hidden variable model in a three-party setting.
Near-linear constructions of exact unitary 2-designs
Authors: Cleve Richard , Leung Debbie , Liu Li , Wang Chunhao
Published: February 2021

A unitary 2-design can be viewed as a quantum analogue of a 2-universal hash function: it is indistinguishable from a truly random unitary by any procedure that queries it twice. We show that exact unitary 2-designs on n qubits can be implemented by quantum circuits consisting of Oe(n) elementary gates in logarithmic depth. This is essentially a quadratic improvement in size (and in width times depth) over all previous implementations that are exact or approximate (for sufficiently strong approximations).
Classification of transversal gates in qubit stabilizer codes
Authors: Anderson Jonas T. , Jochym-O'Connor Tomas
Published: February 2021

This work classifies the set of diagonal gates that can implement a single or two-qubit transversal logical gate for qubit stabilizer codes. We show that individual physical diagonal gates on the underlying qubits that compose the code are restricted to have entries of the form e iπc/2 k along their diagonal, resulting in a similarly restricted class of logical gates that can be implemented in this manner. As such, we show that all diagonal logical gates that can be implemented transversally by individual physical diagonal gates must belong to the Clifford hierarchy. Moreover, we show that for a given stabilizer code, the two-qubit diagonal transversal gates must belong to the same level of Clifford hierarchy as the single-qubit diagonal transversal gates available for the given code. We use this result to prove a conjecture about arbitrary transversal gates made by Zeng et al. in 2007.
Phase diagrams of one-, two-, and three-dimensional quantum spin systems
Authors: Braiorr-Orrs Briiissuurs , Weyrauch Michael , Rakov Mykhailo V.
Published: February 2021

We study the bipartite entanglement per bond to determine characteristic features of the phase diagram of various quantum spin models in different spatial dimensions. The bipartite entanglement is obtained from a tensor network representation of the ground state wave-function. Three spin-1/2 models (Ising, XY, XXZ, all in a transverse field) are investigated. Infinite imaginary-time evolution (iTEBD in 1D, ‘simple update’ in 2D and 3D) is used to determine the ground states of these models. The phase structure of the models is discussed for all three dimensions.

Authors: Tam Nguyen Minh , Quan Pham Minh , Ha Nguyen Xuan , Nam Pham Cam , Phung Huong Thi Thu
Published: February 2021

The coronavirus disease (COVID-19) pandemic caused by a severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has rapidly spread worldwide recently, leading to a global social and economic disruption. Although the emergently approved vaccine programs against SARS-CoV-2 have been rolled out globally, the number of COVID-19 daily cases and deaths has remained significantly high. Here, we attempted to computationally screen for possible medications for COVID-19 via rapidly estimate the highly potential inhibitors from an FDA-approved drug database against the main protease (Mpro) of SARS-CoV-2. The approach combined molecular docking and fast pulling of ligand (FPL) simulations that were demonstrated to be accurate and suitable for quick prediction of SARS-CoV-2 Mpro inhibitors. The results suggested that twentyseven compounds were capable of strongly associating with SARS-CoV-2 Mpro. Among them, the seven top leads are daclatasvir, teniposide, etoposide, levoleucovorin, naldemedine, cabozantinib, and irinotecan. The potential application of these drugs in COVID-19 therapy has thus been discussed.

Published: February 2021

In the present world, smartphones play an important role in the daily life of people. Technological advancement has made smartphones as devices where mobile users can make money transactions or payment by using applications installed on the smartphone. It’s no secret that people today are digital natives. In this technology-driven society, paying for a cappuccino using a pay-and-go method or buying a sweatshirt with a one-click model, has become the norm. Backing away from cash, they drive innovation in the digital payments industry. That’s the reason digital-driven payments become one of the trends ripe in this digital push era.The research is an attempt at analyzing the impact of demographic factors on consumer selection of the mode of payment along with an understanding of what people think about the idea of paying online and up to what extent they find it more convenient. It is also about knowing factors that affect the consumer’s decision to adopt mobile wallets and various risks and challenges faced by the users of the mobile wallet. An extensive literature review is also done and a lot of information is collected from different sources. In this research, the primary data is collected from the people of the National Capital Region. For this research, the convenience sampling method and snowball sampling method of non-probability sampling is used. The tool used for the collection of data and making of questionnaires is google forms and data is collected from 215 respondents. For tabulation and analysis of data, analytical tools like Microsoft Excel and SPSS is used.

Se analizaron las propiedades diagnósticas (sensibilidad, especificidad, y valores predictivos positivo y negativo) de tres definiciones de caso sospechoso de COVID-19 utilizadas en Chile entre marzo y octubre del 2020, y dos propuestas de definición alternativas. La muestra fue de 2 019 personas con resultados conocidos a la prueba de la reacción en cadena de la polimerasa (PCR) para SARS-CoV-2. Para elaborar el criterio 5 se aplicó una regresión logística escalonada (stepwise) optimizando los valores de sensibilidad y especificidad. Se exploró la asociación de variables demográficas, síntomas y signos con la positividad a la PCR mediante regresión logística multifactorial. Se analizaron diferentes escenarios de positividad y se compararon las curvas ROC.

Resultados. La presencia de anosmia (OR = 8,00; IC95%: 5,34–11,99) y fiebre (OR = 2,15; IC95%: 1,28–3,59) y el haber tenido contacto estrecho previo con una persona enferma de COVID-19 (OR = 2,89; IC95%: 2,16–3,87) se asociaron con un resultado positivo de la PCR. Según el análisis de las curvas ROC, el criterio 5 tuvo la mayor capacidad de discriminación, aunque sin diferencias significativas con los otros cuatro criterios.

Conclusiones. El criterio 5 —basado en la anosmia, el contacto estrecho con personas enfermas de COVID-19 y la fiebre como elementos únicos suficientes— tuvo la mayor sensibilidad para identificar los casos sospechosos de COVID-19, aspecto fundamental para controlar la propagación de la pandemia.

ANALOGY OF THE COVID-19 CRISIS AND THE BOSNIAN WAR-SIEGE; PSYCHOLOGICAL, SOCIOLOGICAL AND POLITICAL SECURITY PERSPECTIVE
Authors: HADŽIĆ Faruk
Published: February 2021

The study qualitatively explores the pandemic and Sarajevo War-Siege from the psychological, sociological, and political security perspectives. As a direct indicator of behavioral variability within extreme conditions, the author refers to structural interviews with war-siege participants. The citizens can recognize the 1990s in some manifestations of the pandemic, including crisis staff formation that reflects ethnopolitics (ethnic-political boundaries) rather than instills public confidence. Life in the conditions of radical changes leaves a trace that does not have to be exclusively emotional but cognitive. The state of war-siege meant deconstructing the pre-war way of life and new ways of coping with war conditions. Maintaining routines is a link to pre-war life; continuity of norms and values allows for mental stability maintenance. During the siege, people had an acute perception of space and time. Space was something where the danger came from and the time spent in that space needed to be reduced. We have similar functions during the pandemic, reflecting on people's thoughts. Those who have adequately gone through the trauma that lasted during the siege have adapted well to "extreme" conditions and can develop protective mechanisms. Human thought focuses on the repetitive and familiar in today's world, while some extreme event interprets as the exception; such exceptional events are crucial in creating the future. Regardless of the political system's axis, confidence in the political elites must be sufficient. Prevention of fear and panic in the war's geographical area should be based on quality peacetime preparation through education and psychological commitment.

Contexto: Los estudiantes universitarios enfrentan exigencias académicas y psicosociales en su experiencia escolar, lo que genera un estado acumulativo/progresivo de estrés durante los años que dura este período, y esta situación desencadena consecuencias negativas para su bienestar, tanto físicas como psíquicas. Objetivo: El objetivo de este estudio fue examinar la efectividad de la respiración yóguica (técnicas que procuran rangos de respiración de entre 4 y 8 repeticiones por minuto), mediante un cuasiexperimento con medidas pre-post y grupo de control, además de un análisis del discurso sobre la producción textual realizada, después de experimentar las respiraciones referidas por los estudiantes de la Universidad Nacional de Educación en Ecuador. Metodología: Se utilizó el Cuestionario de Estrés Académico en la Universidad  (CEAU) en una muestra conformada por 73 estudiantes de ambos sexos, con edad media de 19 _ 2 años, seleccionados de la Carrera de Educación General Básica, de primer ciclo. Resultados: Se evidenció, a través del cuestionario y del análisis del discurso aplicado, que la intervención produjo una reducción del nivel de estrés. Se pudo observar que las medias de las escalas del test CEAU en el grupo de control pre y post test se mantuvieron o elevaron, a diferencia del grupo de intervención en los que disminuyeron los niveles de estrés. Conclusiones: Una práctica regular de las técnicas de pranayama, en el contexto áulico, son de mucha utilidad en la reducción del estrés académico.
