Towards a unified representation of linguistic meaning
Authors: Mondal Prakash
Published: February 2023

Natural language meaning has properties of both cognitive representations and formal/mathematical structures. But it is not clear how they actually relate to one another. The central aim of this article is to show that properties of cognitive representations and formal/mathematical structures of natural language meaning, albeit apparently divergent, can be united, as far as the basic properties of semantic structures are concerned. Thus, this article will formulate the form of unified representations for semantic structures. With this goal, this article takes into account standard formal-semantic representations and also Discourse Representation Theory (DRT) representations on the one hand and semantic representations in different versions of Conceptual/Cognitive Semantics (Jackendoff’s, Langacker’s and Talmy’s approaches to Conceptual/Cognitive Semantics) and representations of Mental Spaces (Fauconnier’s approach) on the other hand. The rationale behind the selection of these approaches is that the representations of semantic structures under these approaches are all amenable to unification. It must be emphasized that showing that the representations of semantic structures under these approaches can be unified does not simply amount to unifying these theories/approaches in toto. Rather, it is to demonstrate that cognitive representations and formal/mathematical structures can be shown to be inter-translatable for at least some accounts of linguistic meaning.

The stability of enzymes which play an important role as biocatalysts in many industrial processes is a persistent challenge with significant impact on production costs. In this study, improvement of the stability of α-amylase obtained from Aspergillus fumigatus
was attempted by immobilizing the enzyme onto zeolite using adsorption method. For purification, the isolated enzyme was subsequently subjected to centrifugation, fractionation, and dialysis. The native enzyme was found to have an optimum temperature of 50 °C, while the immobilized enzyme, the optimum temperature of 60 °C was found. The immobilized enzyme was found to have the K
M value of 11.685 ± 0.183 mg mL−1 substrate and V
max of 1.406 ± 0.049 μmol mL−1 min−1, while for the native enzyme, the K
M value of 3.478 ± 0.271 mg mL−1 substrate and the V
max of 2.211 ± 0.096 μmol mL−1 min−1 were obtained. Furthermore, the immobilized enzyme displays the ΔGi of 106.76 ± 0.00 kJ mol−1 and t
½ of 90.40 ± 0.00 min, while the native enzyme, the values obtained are ΔGi of 104.35 ± 1.09 kJ mol−1 and t½ of 38.75 ± 1.53 min. As can be seen, the t
½ of immobilized enzyme is 2.38 times longer than that of native enzyme, justifying a very significant stability enhancement of the enzyme as a result of. Another important finding is that the immobilized α-amylase enzyme was able to retain its activity as high as 13.80 ± 1.19% activity after five cycles, indicating its potential for industrial use.
Loading Rate of Fracture Toughness Tests in Transition Regime
Authors: Lambrecht Marlies , Schuurmans Johan , Scibetta Marc
Published: February 2023

ASTM E1921-21, Standard Test Method for Determination of Reference Temperature, T0, for Ferritic Steels in the Transition Range, contains a limitation on the stress intensity factor loading rate (K˙) for the quasistatic loading. The specimens should be loaded at a rate such that K˙ during the initial elastic portion is between 0.1 and 2 MPa√m/s. However, based on recent improvements in the test technique, it should be possible to narrow the loading rate range in order to reduce variability and have more comparable results between laboratories. For all users to be able to achieve the reduced range, clear guidelines are needed, which are not yet available. The Belgian Nuclear Research Centre (SCK CEN) has extensive experience in fracture toughness testing and has constructed a large database on which statistical studies were performed. This paper illustrates, using the SCK CEN database, that Wallin’s theoretical displacement formulas can only be used in the case in which the compliance of the testing setup is taken into account. An improved equation is proposed, guidelines for implementing the equation are drawn up, and these are verified using the database. It is clear that the methodology is sufficiently robust to provide an average loading rate within the suggested range of 0.5 and 2 MPa√m/s. This methodology could thus be integrated into the testing standard ASTM E1921-21.
Implementation of Manchester codec for information transmission systems based on AVR and ARM architecture microcontrollers

Published: February 2023

ATmega series AVR microcontrollers (e.g., ATmega8A or ATmega16A) and ARM microcontrollers with a Cortex M3 core (e.g., STM32F103С8T6) are among the most popular controllers used in solving engineering problems related to servicing various fire and security alarm sensors and devices for metering household and industrial power consumption. At the same time, to transfer the data via a twisted pair or AC voltage network, it needs to be encoded using Manchester 1 or Manchester 2 code, and said AVR and ARM microcontroller units (MCU) contain no hardware encoder and decoder for the Manchester code.
The study aimed at solving the engineering problem of implementing the codec (encoder-decoder) of the Manchester code based on the hardware interfaces of low-performance microcontrollers.
The direct implementation of the encoding algorithm with the Manchester code using a purely software-driven approach significantly decreases the information transfer rate. At the same time, among the hardware interfaces of the MCU, there is always a serial universal asynchronous data transceiver (UART). However, the UART data transfer protocol is not generally suitable for Manchester encoding and, therefore, needs to be software adapted.
In order to adapt the UART protocol to the conditions of Manchester encoding, the 8N1 mode is selected at the hardware level, which means 8 data bits, 1 stop and 1 start bit. The software implementation of the encoder consists in the fact that out of the total possible volume of 256 code combinations, 16 are selected that satisfy the Manchester 2 code, while the start and stop conditions for data bytes transmitted in a row also satisfy the structure of the Manchester code.
To maximize the efficiency of the program code, all code words are stored in the memory of the MCU in such a way that their serial number corresponds to the decimal interpretation of 4 bits of the input data. The decoding of the received data is also performed as efficiently as possible using the decoding table.
The implementation of the software and hardware codec of the Manchester code significantly expands the scope of popular AVR and ARM microcontrollers and reduces the cost of the finished product by excluding any additional units that perform the function of encoding and decoding the Manchester code.
Pulse converters with reduced output current ripple

Published: February 2023

When developing pulse converters, in order to ensure a low level of output current ripples, one should seek a compromise between the overall size of the elements and acceptable losses in them, while taking into account the dynamic characteristics of power sources as closed systems with feedback. Using multiphase pulse converters can help solve the said problem, but will not ensure a low level of output current ripples in a wide range of the duty cycle of the control pulses. This study aims to find a pulse converter topology capable of ensuring the reduction of the output current ripples, while maintaining the power and volume of the structure. The paper demonstrates the relevance of the study of pulse converters aimed at obtaining a low-ripple output current for powering sensitive loads and gives an overview of ways to reduce the ripples and the most common topologies of converters. The authors describe the results of the practical application of the developed experimental stand and analyze the obtained dependences of the output current ripples on the volumes of the power sections of the converters of different topologies under the same power and frequency. Recommendations are given for choosing the type of converter in each specific case in terms of reducing ripples.

Published: February 2023

The cost of thermophotovoltaic converters can be reduced by making substrates of amorphous materials, which do not have an orienting effect, such as glass or fused quartz, for obtaining thin polycrystalline GaSb layers. The study establishes the conditions for the crystallization of thin polycrystalline GaSb layers with grain size sufficient to produce efficient thermophotovoltaic converter structures on a non-orienting substrate made of fused quartz. The authors carry out a two-dimensional modeling of the initial nucleus growth to study how the crystallization conditions affect the shape of the grains. It is shown that the form of grain growth is not very sensitive to the initial nucleus size and cooling rate, but is rather sensitive to nucleus density on the surface. The paper provides an estimate of the average surface density of the new phase nuclei, which tend to grow, on substrate surfaces. When the temperature is increased, the surface concentration of nuclei grows, and the grain size decreases. It is determined that the selected range of grain surface density corresponds to the cultivation temperature range of 450—550°С. Thin polycrystalline GaSb layers are grown at 520°С with a cooling rate of 10°C/ min to a temperature of 400°C, using a method developed by us, which requires simple equipment and consists in the forced cooling of a thin layer of stibium in a gallium melt in a vacuum. The degree of crystallinity of the samples is estimated from the photoluminescence spectra at 77 K. The spectra show two emission bands: one at 796 meV and another, the predominant one, at 775 meV, which indicates the presence of a significant number of point defects and deviations from the stoichiometry of the obtained films.
The studies performed on an interference microscope show that the obtained layers have good planarity and homogeneity, and the average grain size is up to 25 microns, which confirms the validity of the proposed models. This technology can be used to manufacture inexpensive infrared radiation converters and, in particular, thermophotovoltaic converters.
Influence of electrolyte nature on electrochemical properties of carbon material of plant origin

Published: February 2023

Non-aqueous electrolytes are advantageous for power sources due to the increase in the operating voltage since their electrochemical stability range is much wider. It should be noted that the capacitor’s capacitance depends on the capacitance provided by the electrode material, expressed in F/g, while its voltage and resistance depend on the electrolyte. Therefore, it is very important to study the electrochemical properties of carbon material in aqueous and organic electrolytes and to determine the effect of the electrolyte on the capacitance of the capacitor formed on its basis.
The cathode mixture was made of porous carbon material obtained from biomass and a binding additive. Then, it was pressed onto a nickel grid with an area of 0,5 cm2. A 30% aqueous solution of potassium hydroxide (KOH) and a 0,7-molar solution of tetraethyl ammonium tetrafluoroborate ([C2 H5 ]4 NBF4) in acetonitrile (CH3CN) was used as the electrolyte. The measurements were carried out using two- and three-electrode schemes with a silver chloride reference electrode. Modeling impedance data to equivalent electrical circuits has assisted to establish the influence of the volume charge region in the electrode material on the capacitor’s capacitive characteristics. The specific capacitance values of 125 F/g in KOH and 101 F/g in [C2 H5 ]4 NBF4 are determined by the electrolyte type used and the nature of salts and bases dissolved in it. The practical significance of the obtained results is the application of the developed methods for obtaining carbon material with developed micro- and mesoporous structures and improved physicochemical properties.

Manipulating the Rapid Consolidation Periods in a Learning Task Affects General Skills More than Statistical Learning and Changes the Dynamics of Learning

Published: February 2023

Memory consolidation processes have traditionally been investigated from the perspective of hours or days. However, recent developments in memory research have shown that memory consolidation processes could occur even within seconds, possibly because of the neural replay of just practiced memory traces during short breaks. Here, we investigate this rapid form of consolidation during statistical learning. We aim to answer (1) whether this rapid consolidation occurs in implicit statistical learning and general skill learning, and (2) whether the duration of rest periods affects these two learning types differently. Human participants performed a widely used statistical learning task—the alternating serial reaction time (ASRT) task—that enables us to measure implicit statistical and general skill learning separately. The ASRT task consisted of 25 learning blocks with a rest period between the blocks. In a between-subjects design, the length of the rest periods was fixed at 15 or 30 s, or the participants could control the length themselves. We found that the duration of rest periods does not affect the amount of statistical knowledge acquired but does change the dynamics of learning. Shorter rest periods led to better learning during the learning blocks, whereas longer rest periods promoted learning also in the between-block rest periods, possibly because of the higher amount of replay. Moreover, we found weaker general skill learning in the self-paced group than in the fixed rest period groups. These results suggest that distinct learning processes are differently affected by the duration of short rest periods.

Relapse is a major problem in treating methamphetamine use disorder. “Incubation of craving” during abstinence is a rat model for persistence of vulnerability to craving and relapse. While methamphetamine incubation has previously been demonstrated in male and female rats, it has not been demonstrated after withdrawal periods greater than 51 d and most mechanistic work used males. Here, we address both gaps. First, although methamphetamine intake was higher in males during self-administration training (6 h/d × 10 d), incubation was similar in males and females, with “incubated” craving persisting through withdrawal day (WD)100. Second, using whole-cell patch-clamp recordings in medium spiny neurons (MSNs) of the nucleus accumbens (NAc) core, we assessed synaptic levels of calcium-permeable AMPA receptors (CP-AMPARs), as their elevation is required for expression of incubation in males. In both sexes, compared with saline-self-administering controls, CP-AMPAR levels were significantly higher in methamphetamine rats across withdrawal, although this was less pronounced in WD100–135 rats than WD15–35 or WD40–75 methamphetamine rats. We also examined membrane properties and NMDA receptor (NMDAR) transmission. In saline controls, MSNs from males exhibited lower excitability than females. This difference was eliminated after incubation because of increased excitability of MSNs from males. NMDAR transmission did not differ between sexes and was not altered after incubation. In conclusion, incubation persists for longer than previously described and equally persistent CP-AMPAR plasticity in NAc core occurs in both sexes. Thus, abstinence-related synaptic plasticity in NAc is similar in males and females although other methamphetamine-related behaviors and neuroadaptations show differences.

Dry deposition to the surface is one of the main removal pathways of tropospheric ozone (O3). We quantified for the first time the impact of O3 deposition to the Arctic sea ice on the planetary boundary layer (PBL) O3 concentration and budget using year-round flux and concentration observations from the Multidisciplinary drifting Observatory for the Study of Arctic Climate (MOSAiC) campaign and simulations with a single-column atmospheric chemistry and meteorological model (SCM). Based on eddy-covariance O3 surface flux observations, we find a median surface resistance on the order of 20,000 s m−1, resulting in a dry deposition velocity of approximately 0.005 cm s−1. This surface resistance is up to an order of magnitude larger than traditionally used values in many atmospheric chemistry and transport models. The SCM is able to accurately represent the yearly cycle, with maxima above 40 ppb in the winter and minima around 15 ppb at the end of summer. However, the observed springtime ozone depletion events are not captured by the SCM. In winter, the modelled PBL O3 budget is governed by dry deposition at the surface mostly compensated by downward turbulent transport of O3 towards the surface. Advection, which is accounted for implicitly by nudging to reanalysis data, poses a substantial, mostly negative, contribution to the simulated PBL O3 budget in summer. During episodes with low wind speed (<5 m s−1) and shallow PBL (<50 m), the 7-day mean dry deposition removal rate can reach up to 1.0 ppb h−1. Our study highlights the importance of an accurate description of dry deposition to Arctic sea ice in models to quantify the current and future O3 sink in the Arctic, impacting the tropospheric O3 budget, which has been modified in the last century largely due to anthropogenic activities.

Published: February 2023

The technological method in the field of foundry production is described, which combines additive manufacturing (AM) of disposable foundry polymer patterns with waste polystyrene (EPS) waste disposal. It was created to switch to the method of Lost Foam casting on gasified patterns (LFC), from the current method of casting on printed patterns of fired. The latter method is used because modern printed patterns have a high density and ash content, which degrades the quality of metal castings when used for LFC. EPS disposal gives an environmental effect, and AM patterns are an example of the spread of digitalization and automation of foundry production. Examples of EPS disposal, examples of castings after firing additively manufactured patterns and the ash residue, consisting of carbon, found in the working cavities of molds after firing such patterns are described. Examples of printing patterns with a cellular core and a ventilation channel are shown, an unsuccessful example of aluminum casting by the LFC method in a vacuumed sand mold, as well as an example of a 3D printer for printing using crushed plastic or plastic granules. The developed method of printing one-time foundry patterns for gasification in sand foundry mold corresponds to the trend of spreading AM in foundry production. If the specific weight of the printed pattern is too high, then new LFC methods are used with the removal of excess gases from the gasification of the pattern through the ventilation duct in the pattern and tubular evaporation outside the mold and their oxidation, in particular by our method. Such neutralization of gaseous waste at LFC rightly complements the utilization of EPS solid waste as a raw material for AM foundry patterns, together these methods give a synergistic effect on environmental protection, improving the working conditions of foundries and reducing the cost of cast products while improving its quality.

Published: February 2023

Background

Acute care hospitals increasingly provide care for youth experiencing mental health crises while they await transfer for psychiatric hospitalization. To inform quality improvement efforts, we aimed to characterize hospitalists’ perceptions of health care quality during pediatric mental health boarding and their experiences of moral distress in caring for this population.

Methods

In March 2021, we conducted a web-based survey of hospitalists who participate in the Pediatric Research in Inpatient Settings (PRIS) network. Closed- and open-ended questions queried the quality of care provided to youth during boarding and clinician experience of moral distress in caring for these youth. We iteratively coded qualitative data for emergent themes. Moral distress was measured using 11 items from the Measure of Moral Distress for Health Care Professionals (MMD-HP), which categorizes sources of moral distress into system-, team-, and patient-level factors.

Results

Eighty-eight of 111 PRIS site leaders (79%) and 76 of 383 other PRIS members (20%) responded, representing 12 community hospitals, 38 freestanding children’s hospitals, and 35 children’s hospitals in adult centers. Emergent themes related to health care quality included the following: access to psychiatric services; safety; standardized workflows; clinician training; compassion/patient engagement; and collaboration and disposition planning. Hospitals often lacked desired resources, resulting in poor perceived therapeutic value of care, limited patient engagement, and provider moral distress. Four of the 5 highest MMD-HP item scores were related to system-level factors.

Conclusion

Hospitalists identified several foci for quality improvement and described significant moral distress in caring for youth experiencing boarding, particularly related to health system factors.

Authors: Bendersky Boris Yakovlevich , Chernova Alena Alekseevna
Published: February 2023

The issues of mathematical modeling of turbulent flows in channels with blowing of different cross-sectional shapes are considered. As a result of a series of computational experiments using the OpenFoam tools, the influence of the channel shape on the realized features of flows is investigated. A mathematical model of conjugate heat transfer for the channels under consideration is proposed. Comparison of the results of numerical simulation with the known experimental data has shown the correctness of the proposed models, schemes and algorithms. The topological features of the structure of viscous compressible heat-conducting gas flow in the channels with mass flow of complex shapes have been studied, including the features of the velocity profiles formed in the outlet sections of the channels, the results of calculating the coefficient of non-uniformity of velocity have been described.

Published: February 2023

A three-dimensional mathematical model of coastal water dynamics in the Peter the Great Bay of the Sea of Japan is presented. The system of Navier-Stokes equations is written under the assumption of a hydrodynamic approximation of an inhomogeneous fluid and takes into account turbulent exchange, wind stresses, friction forces, complex topography of the bottom and coastline. On the basis of hydrographic information, a numerical method is used to reconstruct the bottom topography and coastline. The free water surface equation is replaced by a singularly perturbed problem. In the FreeFem++ application software package, a code was written for calculating the hydrodynamic characteristics of coastal waters. During the solution, the finite element mesh is built automatically, the mesh parameters are set by the user. To solve the singular problem, at each time layer, the grid is adapted around the numerical solution with the grid adaptation parameters.

Authors: Facin Paulo Cesar , Silva Giovana
Published: February 2023

Interessados no ensino mais intuitivo da “corrente de deslocamento”, apresentamos brevemente a forma como é introduzido esse assunto em três obras didáticas, que consideramos mais utilizadas nos cursos de graduação. Então abordamos o assunto “corrente de deslocamento” discutindo em detalhes a lei de Ampère-Maxwell para uma carga puntiforme se deslocando com velocidade uniforme e não relativística, com campos elétrico e magnético dados pela lei de Coulomb e a lei de Biot-Savart, tradicionalmente abordados nos cursos de graduação. Mostramos que a corrente de deslocamento tem um significado físico mais intuitivo e que generaliza a densidade de corrente, tornando a equação de Ampère-Maxwell mais simétrica com a lei de Faraday.
The source value of early charters of uncertain chronological status in historical linguistics and onomastics
Authors: Szőke Melinda
Published: February 2023

This paper explores the problem of the source value of charters from the point of view of research in linguistic history. Charters written in Latin often contain elements of the vulgar language (in this case, Hungarian). Only four authentic Hungarian charters have survived from the 11th century in their original form. Therefore, we have also included the non-authentic and non-original charters of the 11th century in our research over the recent decades.

These charters may contain 4–5 chronological layers, and so our task is to separate them. Charters of uncertain status cannot be analysed using the same methodological principles as the authentic and original charters. This paper discusses the methodological principles that may facilitate the identification of the source value of these charters for historical linguistics. Although these principles are defined based on charters from Hungary, due to their universal nature a significant portion of them may also be used successfully in other regions of medieval European charter research.
DISAPPOINTMENT AND REGRETTING REPSENTATIONS IN DUNKIRK AND 1917 MOVIES
Authors: Sulaeman Dedi , Hanifah Anisa
Published: February 2023

The aim of this research was to compare two movies that contain similar perceptions of psychological impact on war, disappointment and regret, from Dunkirk and 1917 movies. Disappointment and regretting arise between British soldiers in movies that were directed by Christopher Nolan and Sam Mendes, which coincidentally both of these films raised the setting in World War I and II. Therefore, this research uses literary criticism and comparative literature methods in examining Dunkirk (2017) and 1917 (2019), to produce both similarities and differences in the psychological and emotional impact on British soldiers. In addition, this research uses a descriptive method with a qualitative approach using Peirce’s sign semiotic analysis. The result of this research is that readers will be able to recognize the differences between the two movies from literary perspective and psychological review from the failures of war in Dunkirk (2017) and 1917 (2019). These two films ultimately interpret disappointment in almost the same way and regret in the form of the loss of a loved one. The behavior of people who experienced both psychological impacts also indicates similarities, sadness, annoyed, and angry. Keywords: disappointment, index, regretting, representations

Polscy przedstawiciele dyplomatyczni w Rumunii w latach 1918–1940. Część I: 1918–1940
Authors: Walczak Henryk
Published: February 2023

Polish politicians had appreciated the importance of relations with Romania since the beginning of the independent Poland, indicating the need for close political and economic cooperation with that country which would serve to resist the Soviet expansion in Central and Eastern Europe. The establishment of official diplomatic relations between Poland and Romania proved to be a rather complex process. It was essentially affected by the lack of agreement between the two centers competing for leadership in Poland, that is the authorities in Warsaw and the Polish National Committee (KNP) in Paris. It was manifested by keeping in Bucharest their own representatives, more or less tolerated by the Romanian, the so-called Legation headed by Marian Linde and the delegate of KNP Stanisław Koźmiński. In the end, Alexander Skrzyński was appointed the envoy of the Republic of Poland and officially recognized by the Romanian authorities. The establishment of official diplomatic relations did not mean, however, immediate rapprochement between the two countries. It was a process lasting almost two years which, thanks to the merits of Alexander Skrzyński, was crowned by signing the Polish-Romanian alliance in March 1921. The next stage consisted of the efforts to strengthen and extend this alliance made by Skrzyński as Minister of Foreign Affairs and Paweł Jurjewicz – his successor to the position of chargé d’affaires, and then an envoy in Bucharest. The process was slowed down by the inept policy of Marian Seyda, the next foreign minister of Poland.

A sentence mood account for Spanish verum
Authors: Kocher Anna
Published: February 2023

This article argues in favor of the idea that verum can result from focus marking on sentence mood. The empirical base are verum strategies in Spanish, English and German. It is shown that all of them result from stress on sentence mood, even though the strategies to express verum in the three languages appear unrelated on a superficial level: German and English rely on stress on a finite verb, Spanish inserts a particle. In the article, a semantic and syntactic account complete each other. The semantic approach is a revised version of Lohnstein’s sentence mood theory of verum focus. The effect of verum in different sentence moods is derived by the function each mood has and the alternatives that focus on them generates. The syntactic analysis is modeled in a cartographic framework (Rizzi 1997 et seq.) and motivates a projection in the lower section of the left periphery dedicated to sentence mood. A focus feature in this projection results in the verum interpretation of the proposition. The principal argument developed in this article is that the superficial differences across languages and clause types result from the fact that the focused mood feature is checked in different configurations.
QUANTIFICAÇÃO MAIS LIMPA DE FIBRAS EM BISCOITOS SALGADOS TIPO CRACKER ATRAVÉS DE FTIR E QUIMIOMETRIA

Neste trabalho apresentamos a implantação e a otimização de um novo método mais limpo baseado em Espectroscopia no Infravermelho com Transformada de Fourier (FTIR) e quimiometria para a quantificação de fibras em biscoitos salgados tipo cracker. Para tanto, 60 amostras de biscoitos salgados tipo cracker oriundos do comércio local de Santa Cruz do Sul (RS, Brasil) foram trituradas e submetidas à análise de fibras por digestão ácida e alcalina segundo o método de referência. As amostras foram também analisadas pela técnica de Reflectância Total Atenuada (ATR) na faixa de 4000-650 cm-1. O conjunto de espectros foi modelado via regressão por mínimos quadrados parciais ortogonais (OPLS) com os dados do método de referência em diferentes faixas espectrais e pré-processamentos. Um modelo ATR/OPLS otimizado foi obtido na faixa de 4000-650 cm-1 com 2 variáveis latentes e dados sem pré-processamento, transformados pela 1ª derivada e por 1 componente de correção de sinal ortogonal. A validação cruzada retornou um coeficiente de determinação de 0,9999 e um RMSECV comprovando assim a validade do método FTIR com quimiometria para esta finalidade

Educação em Saúde consiste na construção de conhecimentos, em que profissionais da saúde, gestores e população trocam informações a fim de promover a saúde. Para tal, é necessário um conjunto de práticas pedagógicas que possam desenvolver a autonomia dos sujeitos no que se refere ao autocuidado e à melhoria da qualidade de vida. Apesar disso, muito se desconhece acerca das formas de acesso e serviços ofertados pelo Sistema Único de Saúde (SUS), ou seja, conhecimentos que também poderiam ser trabalhados na perspectiva da Educação em Saúde. Nesse sentido, a Educação Básica mostra-se essencial na formação plena dos cidadãos, uma vez que potencializa a construção da visão crítica e reflexiva. Por isso, por meio de pesquisa quanti-qualitativa e descritiva, utilizando questionário eletrônico do Google Forms, questionou-se aos gestores e professores da educação básica de escolas do município de Santa Cruz do Sul, no Rio Grande do Sul, sobre seus entendimentos acerca do funcionamento e abrangência do SUS. Foram registradas 331 respostas, englobando 69 escolas da cidade. Em relação à pergunta sobre as portas de entrada do SUS, a maioria dos respondentes tem um bom conhecimento sobre caminhos a serem percorridos pelos usuários em caso de necessidades. Já o segundo questionamento, a respeito das atribuições do SUS, demonstrou que as alternativas relacionadas aos Determinantes Sociais de Saúde (DSS) foram menos assinaladas. Dessa forma, pode-se observar que a saúde é encarada predominantemente pela visão biológica, desconsiderando os fatores sociais e econômicos envolvidos.
