Critical Thinking in the EFL Classroom: The Search for a Pedagogical Alternative to Improve English Learning
Authors: Pineda Báez Clelia
Published: June 2023

This article reports the results of a research study that was undertaken by a group of tea­chers working in the English program ascribed to the School of Education at Universidad Externado de Colombia, with the financial support of COLCIENCIAS. Tasks related to critical thinking were designed and implemented with three groups of students. A qualitative interpretative case study was conducted to examine how students constructed meaning when dealing with the tasks, the meta-cognitive processes involved in the process, the types of interactions built around the tasks and how they influenced language competence and critical thinking. The findings indicate that language competence and criticality are on-going, never-ending processes. However, teachers can refine them through thought-provoking, stimulating materials.

*La investigación-acción mejora la planeación de clases en lengua extranjera
Authors: Quintero C. Josefina , Zuluaga C. Carmen , López P. Margarita
Published: June 2023

This article is derived from an action research project developed at the University of Caldas in Manizales-Colombia with a group of teacher-trainees who are carrying out their teaching practicum at State Schools. It describes the most common problems and the strengths that the practicum advisors have observed at the moment of revising the trainees' lesson plans. It includes some examples taken from the trainees journals with the corresponding advisors suggestions. The researchers describe the intervention points to improve the advising actions that could allow the trainees to reflect on their planning weaknesses. Advisors, as facilitators of that process, feel that there is something to contribute with the pedagogical knowledge about classroom research.

La critica della traduzione di Jiří Levý in relazione al modello analitico di Lance Hewson
Authors: Nanci Giovanna
Published: June 2023

Uno dei campi meno esplorati dei Translation Studies rimane il Translation Criticism. A distanza di più di cinquant’anni dalla prima pubblicazione del volume Umění překladu di Jiří Levý, dove la tematica è già sommariamente trattata, è utile mettere in risalto le intuizioni dello studioso ceco e considerarle alla luce degli ulteriori sviluppi di questo ambito di studio della traduzione, che, anostro modo di vedere, potrebbe aprire le porte ad un nuovo modo di concepire l'aspetto valutativo del tradurre. Indirizzare le finalità e l'esito delle scelte traduttive sugli effetti, che il testo tradotto esercita sul lettore d'arrivo, ci sembra la svolta necessaria rispetto a tanti dibattiti teorici di discutibile valenza pragmatica. Un contributo in tal senso deriva dal metodo di analisi critica dellatraduzione elaborato da Lance Hewson, che mette il traduttore di fronte alle conseguenze delle proprie scelte sul lettore e misura il risultato del suo agire alla luce del potenziale interpretativo e della componente stilistica dell'opera originale.
La tendencia anti-ilusionista en la traducción del texto dramático: reconfiguración del concepto de Jiří Levý
Authors: Odrekhivska Iryna
Published: June 2023

El presente artículo aborda (1) el análisis profundo de la concepción de Jiří Levy sobre la traducción del texto dramático y (2) su potencial extrapolación a las teorizaciones socioculturales actuales de la traducción para el teatro. Teniendo en cuenta las principales orientaciones existentes sobre la evaluación de la traducción del texto dramático, este estudio pone en primer plano las  siguientes premisas y enfoques de Levy sobre la traducción de obras dramáticas: (1) la historicidad relativa del estilo dramático, (2) el papel de la estilización del repertorio de lenguaje de los personajes, (3) el diálogo en escena como un sistema de pulsos semánticos o “energía semántica”, (4) la concretización “interna” del diálogo en la escena, (5) la traducción del texto dramático como una “acción verbal”: hacia el principio de la fidelidad incompatible. El objetivo final es explorar lo que los conceptos puedan aportar al discurso actual sobre la traducción del texto dramático en general y para comprender mejor la traducción y la adaptación o reescritura del texto dramático que también podría probablemente definirse por Levy como anti ilusión. Además, en este artículo se demostrará el carácter formativo de las ideas de Levy en la interpretación de la traducción del texto dramático en Ucrania.
Estilo literario y su transferencia en traducción: Bohumil Hrabal en inglés
Authors: Zehnalová Jitka
Published: June 2023

Este artículo discute el tema del estilo de un autor y su transferencia en traducción teniendo como referente los conceptos de función y estilo de Levý, pero con el argumento de que las ideas de Levý sobre estos conceptos se vieron fuertemente influenciadas por el estructuralismo checo, al mismo tiempo que se adelantaron a desarrollos posteriores en los estudios de traducción y se articulan con investigaciones actuales. El tema central se restringe a dos áreas de investigación: (1) la transferencia de la oralidad estilizada en textos narrativos como aparece en la obra de dos traductores, fenómeno que se discute en términos de la noción de Levý de la toma de decisiones del traductor y los conceptos desarrollados por Mukařovský y Lefever de marco de apercepción y aculturación, respectivamente, al igual que de conceptos desarrollados en los estudios de traducción contemporáneos; (2) contextualización de los textos analizados. La sección empírica se basa en un modelo de análisis textual semiótico orientado a la traducción desarrollado en investigaciones anteriores. Detrás del modelo se encuentra la idea de que para fines de traducción se necesita un enfoque que permita, por una parte, dar cuenta de manera comprensiva de una amplia gama de factores y, por otra, identificar aspectos importantes de un fenómeno de interés. Los datos que son objeto de análisis son dos textos del notable autor checo Bohumil Hrabal (1914-1997), Postřižiny (1970) y Obsluhoval jsem anglického krále (1971), y sus traducciones al inglés, Cutting It Short, traducido por James Naughton, y I Served the King of England, traducido por Paul Wilson.
Projetos de lei de enfrentamento à COVID-19 e sua relação com as competências da Agência Nacional de Vigilância Sanitária
Authors: Oliveira Joyce Carla , De Bem Ivan Pricken
Published: June 2023

Objective: to analyze whether the bills proposed in the Brazilian Chamber of Deputies to combat COVID-19 between 2020 and 2021 are related to the competences assigned to the National Health Surveillance Agency (Anvisa) by Law No. 9,782 of 1999. Methods: data available on the electronic portal of the Chamber of Deputies were collected using the descriptors Anvisa and COVID -19 and Anvisa in 2020 and 2021, resulting in 42 bills which were classified into six groups. Results: it was found that the bills analyzed were related to Anvisa's responsibilities and that the most recurring topics were the distribution, acquisition and/or importation, and registration of products subject to health surveillance, ports, airports, and borders, and services subject to health surveillance. Conclusion: the deputies have proposed bills of national interest related to the pandemic. However, some of these projects have already been regulated by Anvisa authority. It is possible to confirm that parliamentarians tend to respond to issues that arise in the press media to ensure acquisition of inputs to combat COVID-19 and that the bills proposed by the parliamentarians have limited the role of Anvisa.

Authors: Noleto Mariana Brito , Ramos Edith
Published: June 2023

Objective: to demonstrate that Theme 793 of the Brazilian Supreme Court did not pacify public health jurisprudence, but even created new contradictory interpretations due to gaps and contradictions in its text. Methods: this work used the inductive method to explain what caused the sentences of the same Public Health Court, handed down by different judges, but using the Brazilian Supreme Court’s Theme 793 as rationale, to provide different solutions to the same problem. Results: the article highlights the main topics that are subject of jurisprudential divergences in the application of Theme 793 of the Brazilian Supreme Court and connects them to the gaps and contradictions of the Theme. Conclusion: the Brazilian Supreme Court’s Theme 793 gives rise to jurisprudential inconsistencies that cause legal uncertainty and harm the judiciary and public funds.

Authors: Castro Catarina , Colaço Carla , Barata Clara , Fonseca Margarida
Published: June 2023

This study evaluated the implementation and efficacy of the Hands Project – a prevention program for teen dating violence among middle and high school students, implemented during the pandemic. The Hands Project is a brief in-class intervention, targeting the attitudes, personal skills, and the role of bystanders in abusive dating situations with youth. A monitoring process was conducted with 11 classes, and a quasi-experimental evaluation was carried out with 61 students (intervention group n = 45; comparison group n = 16), with pre-test and post-test administration of the Attitudes Toward Dating Violence Scales (ATDV). Program responsiveness and implementation quality were high, and positive significant results were found for female physical violence, indicating a decrease in tolerance for the intervention group, when compared to the comparison group. Discussion reflects on the implications of this study for the implementation and evaluation of teen dating violence programs, and future research regarding this phenomenon.

Authors: ERDOĞAN Seyfettin , YILDIRIM Çağrı , GEDİKLİ Ayfer , YILDIRIM Seda
Published: June 2023

Purpose: Nowadays, the changes in the level of economic activities in the housing market are accepted as the most important signal of macroeconomic performance. This situation brings about the need to give importance to the investigation of policy implementations that affect economic activity in the housing market. So, this study aims to find out the effects of changes in the monetary policy on housing prices in Turkey as a sample of developing country.
Design/methodology/approach: This study employed Augmented Vector Autoregression (VAR) analysis. For housing prices; the Housing Unit price series, calculated by the Central Bank, spanning 2010M1-2016M3 are used. Housing unit price is calculated by Housing price per square meter. To represent production volume, the index of total industrial production has been used. To represent inflation series, CPU (Consumer Price Index) series have been used. The data has been taken from CBRT (the Central Bank of the Republic of Turkey) and TUIK (Turkish Statistical Institute).
Findings: Results show that policy interest rates are important indicators for the related term?s housing prices and it can also be said that the housing price channel has partially been effective. Accordingly, results determined that monetary policy had a significant effect on housing prices in Turkish housing market.
Originality/value: This study supports the argument that monetary policy has a significant effect on housing prices in developing countries like Turkey.
INVESTIGATION OF THE EFFECT OF A DIFFERENT TRAPEZOIDAL INCLINATION ANGLE IN A REVERSE TRAPEZOIDAL CROSS-SECTION FLOW CHANNEL ON THE PERFORMANCE OF THE PEM FUEL CELL WITH THE COMPUTATIONAL FLUID DYNAMIC (CFD) METHOD
Authors: SAYAN Yunus
Published: June 2023

In this work, a reverse trapezoidal cross-section channel shape for a single flow channel PEM fuel cell was examined with computational fluid dynamic (CFD) method. ANSYS Fluent was applied to solve electrochemical reactions, potential fields, mass, species, and energy transport equations. Species mass ratio, temperature distribution and relative humidity were obtained for the cell as well as the i-V and power density plots. The results were compared to two reference geometries with the commonly used square section shape for the channel. One reference geometry has the same channel width and height with the reverse trapezoidal cross-section channel while the other has the same cross-section area. The results indicate that the cell with reverse trapezoidal cross sectional flow channel shape has more than 32% higher power density than the cell with square cross-sectional flow channel shapes, but poor water management.
BALKAN ENDEMİK NEFROPATİSİ ETİYOLOJİSİNDE ARİSTOLOKOLİK ASİT ve LİNYİT HİPOTEZLERİNİN DEĞERLENDİRİLMESİ
Authors: DOĞRUL SELVER Ayça
Published: June 2023

Balkan Endemik Nefropatisi (BEN), Balkanlar’da 1950’li yıllarda tanımlanmış, kronik bir böbrek rahatsızlığıdır. Bulgaristan, Romanya ve Sırbistan gibi ülkelerde Pliyosen yaşlı kömür yataklarının ve BEN’li alanların yayılımının aynı olması sebebiyle BEN etiyolojisi için linyit etkisi öne sürülmüştür. Bu hipotez, kömür ile ilişkili olan yeraltı suyunun linyitleri yıkayarak yapılarındaki toksik organik maddeleri bünyesine aldığını, bu suyun arıtılmadan kullanılmasıyla BEN geliştiğini önerir. Sonraki çalışmalar, bu hipotezin zayıf yanlarını ortaya çıkarırken, nefrotoksik/kanserojenik bazı toksinlere (Aristolokolik Asit ve Okratoksin; AA ve OTA) çeşitli yollarla maruz kalınmasının BEN etiyolojisinde önemli rol oynadığını ortaya çıkarmıştır.

Linyit hipotezini zayıflatan en önemli bulgu, Pliyosen linyit yataklarının bulunduğu diğer ülkelerde benzer böbrek rahatsızlıklarının görülmemesidir. Benzer şekilde, BEN etiyolojisi sadece AA ve OTA’ya maruz kalmakla da açıklanamamıştır. Tek faktörlü etiyolojiyi zayıflatan en temel noktalar şunlardır: BEN-endemik bölgelerde yaşayan tüm bölge sakinlerinin hastalanmaması, BEN hastası olan bir evdeki tüm aile bireylerinin hastalanmaması ve kadınların erkeklere oranla daha fazla hastalanması.

Sonuç olarak, yaygın olarak kabul edilen görüş, BEN gelişiminde çok faktörlü etiyolojinin etkin olduğudur. Çok temel olarak, linyit kaynaklı PAH’ların veya fenollerin, antropojenik kökenli fitalatların ve AA’nın toksik etkilerinin birleşmesi ve genetik yatkınlık gibi sebeplerle hastalığın geliştiği kabul edilmektedir. Bu çalışmada, BEN hastalığı ile linyit ve aristolokolik asit arasındaki ilişkinin incelendiği çalışmalar derlenmiştir.

Authors: GÜNDÜZ Hakan
Published: June 2023

Görüş madenciliği olarak da bilinen duygu analizi bir dizi kelimenin ardındaki görüşü belirlemenin yoludur. Duygu analizi, metinsel bir ifadede iletilen algıyı, düşünceleri ve duyguları daha iyi anlamak için kullanılır. Bu çalışmada Türkçe film sitesi beyazperde.com'dan derlenen film yorumları üzerinde duygu analizi yapılmıştır. Önerilen yöntem ön eğitimli BERTurk modelini temel almıştır. Yapılan ilk deneyde BERTurk modelinin sondan bir önceki dönüştürücü katmanından derin temsiller çıkarılmış ve bu temsiller Destek Vektör Makineleri (DVM) modeline girdi olarak verilmiştir. İkinci deneyde BERTurk üzerinde ince ayarlama yapılarak sınıflandırma gerçekleştirilirken, son deneyde ince ayarlı BERTurk modelinden ilk deneyde olduğu gibi derin temsiller çıkarılmış ve DVM ile sınıflandırma yapılmıştır. Yapılan deneylerde en yüksek doğruluk oranına 0.984 ile ince ayarlı BERTurk temsilleriyle ulaşılmıştır. İnce ayar işlemi sonunda elde edilen temsiller doğruluk oranında yaklaşık %10'luk artışa neden olurken, sınıflandırmada direkt olarak BERTurk yerine BERTurk'ten elde edilen temsiller ile DVM’nin birleşiminin kullanılması yaklaşık %5'lik doğruluk artışıyla sonuçlanmıştır.

Can Higher-Order Finite-Difference Operators Be Applied across a Material Interface?
Authors: Valovcan Jaroslav , Moczo Peter , Kristek Jozef , Galis Martin , Kristekova Miriam
Published: June 2023

It is well known that higher-order and thus longer-stencil finite-difference operators (FDOs) can be advantageously used for evaluating spatial derivatives in the finite-difference schemes applied to smoothly heterogeneous media. This is because they reduce spatial grid dispersion. However, realistic models often include sharp material interfaces. Can high-order long-stencil FDOs be applied across such material interface? We address this question by comparing exact spatial derivatives against derivatives approximated by FDOs with respect to the interface representation, velocity contrast, and order of the FDO. The interface is considered in an arbitrary position with respect to the spatial grid. The material interface exactly represented by the Heaviside step function causes a large error of the FDO spatial derivative near the interface. The maximum error near the interface practically does not depend on the order of the FDO. There are only small differences in errors among FDOs of different orders elsewhere. The larger the velocity contrast, the larger the error. If the material interface is represented using a wavenumber band-limited Heaviside function, the error is smoothed and several times smaller. The error in the wavenumber band-limited model decreases with an increasing order of the FDO. Our findings combined with those by Moczo et al. (2022) lead to the important conclusion: The wavenumber band-limited representation of the material interface is not only a necessary consequence of discretization of the original physical model but also significantly reduces the error in evaluating a spatial derivative using the FDO.

Published: June 2023

Los inventarios en una organización son de alta importancia, ya sea una empresa PYME o de gran tamaño. Tener el control de una manera sofisticada, implica poseer una mayor supervisión del stock, a reducir costos y acelerar el cumplimiento de la demanda. Pues bien, las empresas diariamente tienen nuevos retos y nuevas competencias, por lo cual las impulsa a no solo ser buenas si no excelente, por ende, el crecimiento excesivo de la competencia exige a las compañías tener un mayor nivel de respuesta y de eficiencia en sus procesos para de esa manera poder tener una acogida en el mercado en el que se esté moviendo. En el presente artículo, se tiene como objetivo realizar un análisis de alguno de los métodos implementados por empresas de manufactura, con el fin de demostrar la importancia de la gestión de inventarios. Es importante no incurrir en errores tales como, no considerar los tiempos de reabastecimiento de los proveedores. La problemática de cuantificar el inventario puede ser tan grande o tan pequeño según la gama del producto, en el tiempo muchas  compañías  han sufrido con esto por los costos y la productividad que representa, el tener mucho inventario sin rotación denota una gran pérdida ya que, el stock de una empresa es uno de los puntos más importantes a tener en cuenta porque representa uno de los activos más grandes, y a su vez, supone generalmente la mayor inversión de una organización, la cual puede abarcar una cantidad superior al 50% del total de activos de una empresa distribuidora.

Published: June 2023

Debido al constante crecimiento en las operaciones de importación y exportación, ha aumentado en igual medida el comercio marítimo mundial, especialmente por su seguridad, eficiencia y economía comparado con otros modos de transporte. Sin embargo, el transporte marítimo ha sido uno de los causantes del impacto negativo que incide sobre el medio ambiente, debido a la contaminación generada por los buques que produce el deterioro de nuestra capa de ozono por las emisiones de compuestos orgánicos gaseosos que a su vez promueven la extinción de las especies y su hábitat marino por derrames de líquidos tóxicos, despojamiento de aguas lastres, caídas de contenedores al mar, entre otras fuentes contaminantes. Es por lo anterior que se realizó un estudio de carácter cualitativo basado en estadísticas, información de organismos encargados de la regulación del sector, convenios internacionales para la prevención de la contaminación marina por buques, artículos de revistas científicas y estudios existentes sobre la cantidad de contaminación marina que se produce a causa del transporte marítimo y a través de esta información identificar las estrategias que promueven el desarrollo e implementación de la logística verde en el sector mencionado con el fin de mitigar la contaminación que este genera.

Aplicación de Metodología SLP para Redistribución de Planta en Micro Empresa Colombiana del Sector Marroquinero: Un Estudio de Caso
Authors: Álvarez-Arias Daniel , De Ávila-Moore Jeniffer , Hurtado–Rivera Josué
Published: June 2023

La distribución optima en una planta o edificio permite desarrollar actividades de manera segura, que se desarrollen en el menor tiempo posible; eficiencia de uso de espacios y optimización de flujos internos. La metodología systematic layout planning (SLP) diseñado por Richard Muther en 1968, permite resolver problemas de distribución de planta, esta utiliza criterios cuantitativos para diseñar una distribución con el fin de aumentar el nivel de productividad y reducir costos.

Se aplica la metodología SLP en una microempresa marroquinera del sector industrial colombiano donde, en esta actualmente, se presentan retrasos en sus operaciones, ineficiencia en la utilización de espacios, dificultades para el manteniendo de su planta y reducción en su productividad. La microempresa desea redistribuir la planta con fines de incrementar su capacidad productiva y optimizar el desarrollo de sus operaciones. Se establece una redistribución en planta mediante técnicas de estudio del trabajo e implementando la metodología SLP, donde se definen las relaciones de espacio y de proximidad entre áreas. La redistribución óptima se obtiene mediante el estudio, diseño y evaluación de diversas alternativas de distribución.

Por medio del SLP, se propone una redistribución de planta que permite minimizar los retrasos en las operaciones, aumentar la eficiencia en el uso de espacios, realizar mantenimientos y monitoreo de una manera más óptima a los procesos. Por otra parte, permite incrementar la capacidad productiva a partir de la reducción de recorridos, también, contribuye a la mejora del flujo interno y reducción de la congestión de este.

Aims: to study the content of regulatory peptides in the hypothalamus and pituitary gland, as well as sex steroids in the gonads in rats of both sexes with Guerin’s carcinoma against the background of hypothyroidism. Materials and methods. Our experiment was performed in white outbred rats of both sexes with induced hypothyroidism, against the background of which Guerin’s carcinoma was transplanted. In 1% homogenates of the pituitary and the hypothalamus and in 10% homogenates of the gonads in the animals from the main and reference groups, the levels of GnRH (Casabio, China) were determined by the ELISA method using standard kits, and the content of LH, FSH, estradiol (E2), testosterone (T) and progesterone (P4) by the RIA method (Immunotech, Czech Republic).

The original herbal formula of homeostasis regulator Multiphytoadaptogen (MPhA) for preventive oncology developed by the N.N. Blokhin Center of Oncology containing phytocomponents from Schizandra chinensis has been investigated in vitro, in vivo and in clinical studies. The MPhA multi-target effects are achieved by optimizing the functioning of the nervous, immune and endocrine defense systems that regulate homeostasis under stress. Everything that has been previously studied for MPhA can be considered as preclinical testing, including clinical research, which can be regarded as the pilot studies. This was allowed because MPhA in Russia is registered as a parapharmaceutical agent and therefore standardized according to established requirements. However, due to the high efficiency of MPhA, a detailed study of the chemical composition and standardization of it is required, including the composition of Schisandra chinensis Baill (Schisandraceae) active components, which turned out to be translocated into MPhA as a result of the extraction technology developed. So, for MPhA identification and standardization we detected the secondary metabolites in the herbal formula MPhA as well as in fruits extract of Schisándra chinénsis using high-performance liquid chromatography in combination with mass spectrometry. Chromatography was performed on an ACQUITY UPLC BEH C18 column in a gradient mode. A TSQ Vantage triple quadrupole mass spectrometer with electrospray ionization was used. Lignans Schizandrin and Schizantherin A were identified in the MPhA as well as in Schisándra chinénsis fruits extract obtained by the technology developed. The determined secondary metabolites can be used for standardization and quality testing of the herbal formula MPhA. In addition, we performed in silico analyzes of Schizandrin and Schizantherin A biological activity spectra using computer program PASS (Prediction of Activity Spectra for Substances). Schizandrin and Schizantherin A activities, according the scientific literature and in silico analysis, correspond to the properties studied for MPhA which therefore fits into the concept of a drug – homeostasis regulator adaptogen for preventive oncology.
Trigeminy electrocardiogram spectral characteristics study
Authors: Proskurin S.G.
Published: June 2023

This paper presents the results of a study in which the method of ECG decomposition in the time domain (DMTD) was applied, followed by a spectral analysis. A digital signal with trigeminy of the first lead of a standard electrocardiograph was processed. Using digital filtering in time domain, the electrocardiogram (ECG) was cleared of noise, what results the reduction of spurious components by 10-20%. To represent and classify the frequency characteristics throughout the entire processed cardiac signal, the QRS complexes were removed, P and T waves were left unchanged. Due to considerable influence on the spectral analysis sharp peaks of the ECG signal with small characteristic times of the leading and trailing edges, the obtained result differs considerably from the sum of the harmonic components of the smooth part of the signal. The spectral processing reveals peaks at multiple frequencies, 1.6 Hz, 3.2 Hz, 4.7 Hz, corresponding to a smooth function of P and T waves before the appearance of extra systoles. Based on the obtained data, the frequencies corresponding to the peaks of the cardiogram with a stable sinus rhythm were identified. The acquired data represent regular harmonics, which allow adequate quantitative ECG analysis.

The selection process for scholarship grantees at Universitas Muhammadiyah Yogyakarta (UMY) still utilizes the conventional method, namely Microsoft Excel. It is conducted by inputting all student data, then sorted from the highest to the lowest. Scholarships for prospective new students must be right on the target, meaning that they meet the criteria for students eligible for scholarships. It is intended not to harm other prospective students who should get scholarships. In previous studies, the classification process used many algorithms such as Naive Bayes, C.45, Decision Tree, k-Nearest Neighbor, and Support Vector Machine. The use of the Support Vector Machine algorithm employed a two-class classification. Support Vector Machine and Decision Tree algorithms are two classification methods that can obtain precise and accurate results. This study aims to use the Multiclass Support Vector Machine (LibSVM) algorithm to classify the achievement scholarship rankings for new students. The minimum amount of data used affected the classification results. From the 2015 to 2019 data, the highest amount of data was 2015, obtaining the highest accuracy result of 84.34% using the sigmoid kernel type and the k-fold value of 3. The classification was based on the entry system stages. PMDK stage 2 obtained an accuracy of 81.38%, with the most data amounting to 268 from stage 3.

Heart health is a basic human right and a crucial component of global health justice. In an ever-more-advanced age, every task becomes simple due to science, technology, and information development. However, certain tasks are still performed manually. Therefore, innovation in computerized system design is required. The human heart area calculation was performed by combining image processing and deep learning techniques. Deep learning is a scientific subfield of machine learning, while image segmentation is a step in image processing. This study employed the U-Net segmentation method to identify different stages of heart area calculation. U-Net could conduct image segmentation with the small training dataset accurately. This study’s population consisted of 800 chest X-ray images obtained from the Kaggle website, with human hearts as the sample. The findings revealed that the training data with the U-Net architecture model acquired an accuracy of 09.98. However, the testing data accuracy was still determined manually. In this work, the U-Net model employed an input shape measuring 256x256, a kernel size of 3x3, and 50 epochs.
