Imitating the Human Resources Migration among Megapolises «Social Code»
Authors: Amentes Artem
Published: November 2023

In the modern world, the role of humans is decreasing due to the introduction of automation. The improvement of objects of labor gradually made it possible to move from handicraft production to industrial production. In the 21st century, we are faced with the fact that those types of activities that are defined as intellectual, creative, creative today can be replaced by artificial neural networks trained to generate previously unknown texts, graphic images, photos and video materials. The decline in the role of man in sectors of the economy leads us to the question of revaluing the role of man as a participant in the socio-economic process. In the context of government, this largely determines a new approach to accounting for human resources and human capital. It is necessary to develop a general approach to formalizing the process of assessing a person, since modern science does not have a unified approach to this task. A unified approach to determining the value that each citizen accumulates throughout his life should be formed for further modeling of socio-economic processes. The described approach is intended to reduce uncertainty factors in models that simulate socio-economic processes in society. Research shows that people make decisions irrationally, and this irrationality must be measured. The models by which modern society is built have faced a number of challenges over the past decade. Problems in the field of healthcare, logistics, banking sector, and widespread use of artificial intelligence have highlighted the importance of flexibility in socio-economic structures, which can be achieved by increasing structural completeness. Formalizing the description of a person from the point of view of psychological and behavioral characteristics will improve the descriptiveness of models, increase their complexity, which means they will become stable and flexible for modern challenges.
Agent-based Approach to Forecasting Modern Demographic Cycles
Authors: Rossoshanskaya Elena
Published: November 2023

The article is devoted to the problem of choosing tools for forecasting modern demographic cycles. In the process of scientific research, the authors carried out a detailed analysis of the theoretical and methodological foundations for studying the cyclicity of the present and future demographic dynamics and obtained the following results, which constitute the scientific novelty of the work performed: 1) systematized approaches to understanding the essence of the term «demographic cycle» in the broad and narrow senses; the concepts of «demographic cycle» and «demographic wave» are divorced, the properties of demographic cycles are formulated; based on the analysis of various classifications of the phases of demographic cycles, an assessment of the possibility of their application to the study of modern demographic dynamics is made; 2) three groups of factors for the formation and maintenance of modern demographic cycles are identified: the structure factor, the environmental factor, the behavior factor, and the need for their joint consideration when predicting the cyclical nature of demographic processes in the long term is substantiated; 3) a comparative description of the main approaches to modeling and forecasting demographic cycles is given, the following are considered: the classical population model of R. Pearl, described by the Verhulst logistic equation; extrapolation models, including those based on Fourier series; cohort component method; agent-based modeling; 4) the advantages of using agent-based modeling to study the cyclicity of demographic processes in the long term are substantiated. The potential of the agent-based approach is revealed on the example of the agent-based demographic model of the Far East, implemented by the research team of Eastern State Planning Center.
The Role of Eating Behavior in the Context of World Trade Wars
Authors: Burilina Maria
Published: November 2023

In the context of globalization, the question of trends in eradicating hunger and creating bio-available products around the world is increasingly being asked. However, in the era of global trade wars, such a slogan can turn into a biological weapon for poor countries. In developed countries, the trend towards reducing the consumption of lactose, gluten and other food irritants is increasingly developing, while at the same time the number of infant deaths from malnutrition and anemia is growing in African countries. The work examines the challenges that await countries in the event of global trade wars and the threats that arise to them in conditions of limited eating behavior, which plays an important role in the development of countries and the fight of some of them against hunger.

EFECTO DE LA SENSIBILIZACIÓN EN OXIDACIÓN FOTO-CATALÍTICA
Authors: Páez Mozo Edgar A.
Published: November 2023

Se presentan los resultados de investigaciones sobre la actividad foto-oxidativa de sólidos sensibilizados con diferentes compuestos de coordinación. Estos materiales se han empleado en procesos de oxidación selectiva y de oxidación avanzada. La sensibilización del TiO2 con complejos del tipo MoVI(O)2 (L)4 facilita el proceso de transferencia del oxígeno molecular a sustratos como la PPh3 y ciclohexeno bajo iluminación. La sensibilización con ftalocianinas metálicas (TSPcM/TiO2) donde M = Co, Ni, Cu y Zn muestra una sinergia que se evidencia por un aumento en la velocidad de reacción de oxidación del ciclohexeno en medio orgánico independiente del metal central. La presencia de depósitos de platino en el TiO2 sensibilizado con carboxiftalocianinas presenta un incremento en la foto-oxidación del fenol en medio acuoso, bajo irradiación con luz visible. La oxidación de mercaptanos con ftalocianinas intercaladas en sólidos básicos (Hidrotalcita y zeolitas) es posible en ausencia de un medio alcalino externo y bajo iluminación se generan productos de oxidación avanzada.

SÍNTESIS Y CARACTERIZACIÓN DE PEROVSKITAS DOBLES TIPO SR2FEMOO6
Authors: Lopéz K. , Mariño A.
Published: November 2023

En este trabajo se investigaron las propiedades eléctricas y magnéticas de perovskitas dobles del tipo Sr2FeMoO6 preparadas por reacción de estado sólido utilizando dos rutinas y diferentes tiempos de síntesis: síntesis en atmósfera reductora y síntesis en vacío. Las muestras se analizaron en su morfología y estructura mediante microscopía de fuerza atómica y difracción de rayos X respectivamente. La caracterización eléctrica presentó esencialmente un comportamiento semiconductor en el rango de temperaturas medido (160K-320K) y magnetorresistencia a bajas temperaturas. Las mejores características magnetorresistivas se observaron en las muestras producidas en vacío. Las variaciones en las propiedades eléctricas y magnéticas observadas se pueden asociar a factores tales como el desorden catiónico y a las impurezas presentes.
COMPARACIÓN DE LOS TRATAMIENTOS EN RADIOTERAPIA CONVENCIONAL Y CONFORMAL PARA CÁNCER DE PRÓSTATA POR MEDIO DE DOSIMETRÍA TERMOOLUMINISCENTE
Authors: Mahecha L. , Plazas M.C. , Machado H. , Perea S.
Published: November 2023

En el tratamiento del cáncer de próstata, la dosis prescrita por el médico oncólogo depende de la extensión de la enfermedad y de la dosis de tolerancia de los tejidos adyacentes normales. Para lograr un óptimo control tumoral en estadios tempranos y localmente avanzados, es necesario escalar la dosis con probabilidad baja de morbilidad a nivel rectal y vesical. Esto se logra por medio de la radioterapia conformal. En el Instituto Nacional de Cancerología, esta técnica es usada, pero surgen dos interrogantes de los radioncólogos y físicos médicos: de acuerdo a los protocolos clínicos, la técnica conformal entrega una dosis menor a las estructuras adyacentes, ¿existe un método experimental que verifique dosimétricamente la certeza de esta afirmación?, y ¿los sistemas de planeación dosimétricos calculan adecuadamente las dosis en los diferentes órganos como lo recomiendan los protocolos de control de calidad en radiaciones ionizantes del Organismo Internacional de Energía Atómica? Este trabajo pretende dar respuesta a estas preguntas. Mediante dosimetría termoluminiscente y utilizando simuladores físicos, se midió la dosis absorbida en el volumen blanco y en los tejidos adyacentes en radioterapia conformal y convencional. Se mostró que órganos como recto y vejiga reciben menor dosis en radioterapia conformal, disminuyendo de esta forma su probabilidad de morbilidad. Adicionalmente, se compararon las lecturas de los dosímetros termoluminiscentes con los valores de las dosis suministrados por el sistema de planeación dosimétrico Eclipse, concluyendo que la dosis prescrita al paciente es la realmente entregada como lo exige los programas de control de calidad en radioterapia.

Recurso humano y distancia geográfica como barreras de acceso a los servicios de salud, Caquetá, Colombia, 2020: análisis cuantitativo y desde la perspectiva de los actores del sistema de salud
Authors: Beltrán-Cleves María Virginia , Estrada-Montoya John Harold , Durán-Torres Carlos Felipe
Published: November 2023

Introducción: históricamente, el acceso a los servicios de salud ha sido medido a través de las tasas de aseguramiento de una población; sin embargo, este abordaje ha sido ampliamente cuestionado en tanto no proporciona cifras de acceso efectivo, considerando que los individuos enfrentan diversas barreras para acceder a la prestación de servicios de salud, las cuales se agudizan en territorios remotos. Objetivo: determinar si el número de prestadores y profesionales de salud, así como su distribución geográfica, constituyen barreras de acceso a los servicios de salud en el departamento del Caquetá, Colombia; a su vez, se pone en evidencia la percepción de algunos actores del sistema frente a estas barreras. Materiales y métodos: estudio mixto descriptivo de corte transversal. En la fase cuantitativa se recolectaron datos secundarios a través de consulta en bases de datos, y se aplicó un sistema de medida de distancia/tiempo de viaje; mientras en la fase cualitativa se realizaron entrevistas semiestructuradas a actores del sistema de salud. Resultados: de los 16 municipios, tres tienen barrera de acceso a los servicios de salud, dos por vía terrestre y uno por vía fluvial. Hay un trabajador de la salud por cada 1000 habitantes. Los hallazgos de las entrevistas semiestructuradas se clasificaron dentro de seis categorías. Conclusiones: los habitantes del Caquetá enfrentan barreras de acceso geográficas y de falta de recurso humano. El sistema de salud colombiano requiere fortalecerse desde el enfoque de los determinantes sociales de la salud con el fin de mitigar dichas barreras.

Introducción: las bacterias patógenas con mecanismos de resistencia a antibióticos pueden ser adquiridas en las ambulancias cuando se presta un servicio de salud de emergencia. Esta situación puede generar infecciones asociadas al cuidado de la salud. Objetivo: realizar la caracterización fenotípica y el perfil de sensibilidad de bacterias recuperadas en ambulancias APH del municipio de Medellín. Metodología: se realizó un estudio descriptivo durante los años 2017 - 2019 en el que se incluyeron 10 ambulancias de Atención Prehospitalaria (APH) de la Secretaría de Salud de Medellín. Se realizó un muestreo de superficies y ambientes a las ambulancias y al personal de salud de APH (hisopado de manos). Se evaluó la presencia de microorganismos indicadores como mesófilos aerobios, coliformes totales, mohos y levaduras. Adicionalmente se determinó la presencia de microorganismos patógenos como Staphylococcus aureus y Escherichia coli. A las bacterias recuperadas se les realizó identificación fenotípica y pruebas de sensibilidad mediante el Sistema Vitek 2 de Biomérieux®, además se emplearon medios cromogénicos de Biomérieux® para la detección de bacterias con mecanismos de resistencia de importancia clínica. Resultados: el 55,4 % de los aislados bacterianos corresponden a Cocos Gram positivos, 34,5 % a Bacilos Gram positivos y 10,1 % a Bacilos Gram negativos. La distribución por tipo de muestras fue: en los manipuladores, en el ambiente de la cabina y en la camilla predominaron los Cocos Gram positivos, en el botiquín los Bacilos Gram negativos. El principal género recuperado correspondió a Bacillus spp 25,9 %, seguido de Staphylococcus spp 22,3 %. A excepción de Stenotrophomonas maltophilia no se recuperaron bacterias con mecanismos de resistencia de importancia clínica. Conclusión: si bien no se recuperaron bacterias con mecanismos de resistencia de importancia clínica, la presencia de Stenotrophomonas maltophilia, bacteria intrínsecamente resistente a los antibióticos, y asociada con infecciones hospitalarias, sugiere que es necesario evaluar los procesos de desinfección detalladamente y continuar con la vigilancia epidemiológica de los microorganismos presentes en las ambulancias.
El derecho al aborto legal, seguro y gratuito en Argentina: obstáculos y desafíos de la política en acto a 18 meses de su implementación (2021-2022)
Authors: Anzorena Claudia C
Published: November 2023

En enero de 2021, en Argentina, entró en vigor la Ley 27.610 de Interrupción Voluntaria del Embarazo, que habilita el aborto voluntario hasta la semana 14 y sin plazos en caso de violación o riesgo de la salud de la mujer, la niña o la persona gestante. Desde una perspectiva feminista y de la salud colectiva, esta ley plantea grandes desafíos en los procesos de implementación de políticas de derechos sexuales y reproductivos en el sistema de salud. En este artículo buscamos atender a los procesos de formulación de la estrategia política, la organización de la atención y la acción técnico-administrativa de la política en acto, para explorar los obstáculos y desigualdades en el acceso a la ley. Asimismo, hacemos hincapié en las articulaciones entre el personal de la salud, funcionarios/as y activistas, para comprender las relaciones entre intervención estatal y prácticas/experiencias. La estrategia metodológica es de tipo cualitativa. Las principales técnicas de recolección de datos son el análisis documental y de instrumentos de políticas.

Published: November 2023

The objective of this research is to investigate the relationship between the brand image of premium hotels in China, the level of customer engagement they experience, and their intention to make a purchase at one of those hotels. The study model that was developed made use of something called the Theory of Planned Behavior (TPB). Using a method known as convenience sampling, samples were collected from people living in Beijing, China. Participants in the poll who intended to make reservations at upmarket hotels were given the survey questionnaires. A grand number of 459 specimens were collected for the purpose of analysis. The process of data analysis and validation of the research hypotheses was conducted using SmartPLS. This research provides evidence that there is a connection between customer engagement and brand image, as well as the purchase intention. According to the findings of the study, the relationship between a brand's image and a consumer's propensity to make a purchase is diminished when customer engagement and brand image factors are both present. As a result, the efficacy of customer interaction as a mediator was shown to have been demonstrated. The academician is presented with new information in the form of this result, and further discussion is given regarding its application to practitioners.
CEO gender and firm performance: It is the predecessor-successor gender combination that matters!
Authors: Bozionelos Nikos , Lan Yingbing , Xu Yifan
Published: November 2023

This study was set to provide a response to the following question: What is the relationship between the gender of CEO successor and firm performance? We analyzed data from 4,338 CEO successions in companies listed in China Stock Exchanges from 2001 to 2016. We utilized Propensity Score Estimation for multiple treatments to operationalize different gender combinations in CEO succession (male-to-male, male-to-female, female-to-male, female-to-female). Findings suggested that it is CEO succession with different gender instead of a female successor that hurts firm performance. We also found that the power of female successors serves as a moderator: it can mitigate the negative impact of different-gender CEO succession on firm performance. The results also indicated that firm ownership (state-owned vs. non-state owned) influences the relationship between female-male CEO succession and firm performance. Practical implications: The findings imply that the gender of the CEO per se may not be the prime factor in firm performance, instead what firms should pay attention at is to smoothen the succession processes when a CEO of different gender is appointed.
Statistical assessment of employees’ perception of nonmonetary compensations: The case of a regional hospital
Authors: Ojemakinde Abiodun , Mwaura-Smith Elizabeth
Published: November 2023

Organizations often attempt to incentivize employees with nonmonetary rewards for the purpose of increasing workers’ productivity.  The problem is that employers don’t always know which nonmonetary rewards are most beneficial to the employees and the organizational goal. Therefore, we attempt to investigate the statistical significance of employees’ perceptions of nonmonetary rewards at the workplace. A questionnaire was administered to the employees of the Accounting Department of a regional hospital to indicate their perception of the relevance of the nonmonetary rewards available to them vis-à-vis their work productivity. Employees’ preference for each of the five nonmonetary rewards was measured on a binary scale of yes, the nonmonetary reward was valuable, or no, the nonmonetary reward was not valuable. The acquired data underwent analysis to examine the proportion of workers who expressed a preference for one nonmonetary reward over another. This analysis was conducted using the conventional normal probability distribution, ensuring that the condition of a large sample size was satisfied. We concluded that not all nonmonetary rewards were considered valuable by the employees and that supervisors’ recognition of workers’ good ideas at work and collegiality with coworkers were considered prime nonmonetary rewards. Additionally, non-monetary rewards that have no close substitutes or that employees cannot easily provide for themselves—such as supervisors praising employees for their creative ideas at work—are significant drivers of engagement and productivity in small- and medium-sized businesses like the one used for our research. This research provides managers with empirical and valuable information regarding nonmonetary incentives and reward programs.

Maternal and Fetal Factors Affecting Cell-Free Fetal DNA (cffDNA) Fraction: A Systematic Review
Authors: Zaki-Dizaji Majid , Shafiee Arman , Gargari Omid Kohandel , Fathi Haniyeh , Heidary Zohreh
Published: November 2023

Background: Cell-free fetal DNA (cffDNA) is a novel screening method for fetal aneuploidy that facilitated non-invasive prenatal testing (NIPT) through analysis of cffDNA in maternal plasma. However, despite increased sensitivity, it has a number of limitations that may complicate of its results interpretation. Therefore, elucidating factors affecting fetal fraction, as a critical limitation, guides its clinical application.
Methods: In this report, systematic search was carried out through PubMed, Web of Science, and Scopus databases until February 11, 2022 by using keywords consist of "noninvasive prenatal screening", "NIPT", "noninvasive prenatal", "cell free DNA" and "fetal fraction". The articles were screened for eligibility criteria before data extraction.
Results: A total of 39 eligible studies, most published between 2010 and 2020, were included. Based on the results of studies, a negative correlation between maternal age and BMI/body weight with fetal fraction was found. Furthermore, LDL, cholesterol, triglyceride level, metformin, heparin and enoxaparin therapy, hemoglobin-related hemoglobinopathies, and physical activity showed to have negative associations. Interestingly, it seems the ethnicity of patients from South and East Asia has a correlation with fetal fraction compared to Caucasians. Positive correlation was observed between gestational age, free β-hCG, PAPP-A, living in high altitude, and twin pregnancy.
Conclusion: Considering each factor, there was significant inconsistency and controversy regarding their impact on outcomes. Indeed, multiple factors can influence the accuracy of NIPS results, and it is worth noting that the impact of these factors may vary depending on the individual’s ethnic background. Therefore, it is important to recognize that NIPS remains a screening test, and comprehensive pre- and post-NIPS counseling should be conducted as part of standard clinical practice
Establishment of Cut-off Values for Uterine and Peripheral Blood Natural Killer Cells During the Peri-implantation Period in Fertile Controls and Women with Unexplained Recurrent Implantation Failure
Authors: Singh Neeta , Dogra Yogita , Kumar Pawan , Mathur Sandeep , Sharma Ashok , Patel Garima
Published: November 2023

Background: The purpose of the study was to determine the cut-off values for peripheral and uterine natural killer (pNK, uNK) cells in fertile controls and in women with recurrent implantation failure (RIF).
Methods: In this study, 50 women with RIF and 50 fertile controls were enrolled. Midluteal endometrial biopsy samples from both cases and controls were obtained for CD 56+ cell immunohistochemistry labeling to identify uNK cells. Peripheral venous blood was also taken during the biopsy to detect pNK cells in peripheral blood mononuclear cells using flow cytometry. Cut-off values were obtained from fertile controls. Using a non-parametric Mann-Whitney U-test, the medians of the data sets were compared.
Results: The median values for uNK and pNK cell levels in the control group were 7% and 11.6%, respectively. The median value for uNK cells in RIF patients was 9%, which was higher than the one in controls but not statistically significant (p-value of 0.689). The median pNK levels (11.6% vs. 12.4%) were comparable between the RIF group and the controls. Moreover, it was found that 68% of individuals had uNK cell counts below the reference value, while 32% had excessive levels exceeding 7%. Additionally, only 51.4% of the RIF group had increased pNK cells.
Conclusion: The pNK cell cut-off values need to be used with caution because there was no difference between fertile controls and RIF women. If immunotherapy is recommended for RIF women, uNK cell testing should be used as the preferred approach.
A Rare Case of 45,X/46,X,del(Y)(q12→qter) Mosaicism in An Infertile Male with Y Chromosome Microdeletion
Authors: Kumar Patel Sunny Kumar Jignesh , Kabir Rahul , Nayak Ruchismita , Palo Indira , Banerjee Birendranath
Published: November 2023

Background: Males with 45,X/46,XY karyotype have two different types of cells. This condition is associated with a wide range of clinical phenotypes. In infertile males, the mosaic 45,X/46,XY karyotype is a frequent sex chromosome defect and they might be able to conceive with the help of assisted reproductive technology; nevertheless, there is a potential risk of transmission of azoospermia factor (AZF) microdeletions in addition to 45,X to all the male progeny. In this case report, the purpose was to present a rare sex chromosomal mosaicism of an infertile man.
Case Presentation: Comprehensive molecular and cytogenetic analysis of an infertile male was performed in this case study. A 27-year-old male was presented with history of azoospermia and was unable to conceive after being involved in five years of marriage. Cytogenetic investigation revealed a rare mosaic karyotype pattern of 45,X/46,X,del(Y)(q12→qter). Y chromosome microdeletion (YMD) analysis revealed notable deletions of 06 loci. Comparative genomic hybridization (CGH) microarray was performed to investigate probable functional genetic associations.
Conclusion: Deletion of Y-linked genes leads to different testicular pathological conditions contributing to male infertility. Individuals with normal male phenotype harbor YMD, although size and location of the deletion do not always correspond well with quality of sperm. Therefore, in addition to semen analysis, identification of genetic variables is important which will play a crucial role in proper diagnosis and management of infertile couples. The present case study demonstrates the significance of comprehensive molecular testing and cytogenetic screening for individuals with idiopathic infertility.

Authors: Mahmoodabad Seyed Saeed Mazloomy , Zeidabadi Batool , Rajabalipour Mohammad reza
Published: November 2023

Introduction: Iran has the highest annual fatality rate in traffic accidents among countries in the world.  This study is designed to predict the protective behaviors of intra-urban traffic accidents based on the constructs of the theory of planned behavior (TPB).
Methods: This descriptive-analytic study was conducted in 2022 in Yazd city on 140 people with driver's license using stratified random sampling method. Data were collected through a questionnaire with three parts including demographic variables, evaluation of the TPB constructs, and assessment of socio-cultural factors of driving behaviors.  Data analysis was performed by SPSS version 26 using one-sample t-test, Chi-square, and univariate linear regression tests.
Results: In this study, the mean age of subjects was 39/1 with a standard deviation of 11. Based on the results of the study, 33% of the variance related to protective driving behavior could be predicted with the variables included in the model. The constructs of behavioral intention (β=0/414, p<0/0001) and perceived behavioral control (β= 0/246 p= 0/003) were the determinants of protective behaviors in Yazd city drivers.
Conclusion: In the present study, the perceived behavioral control was the strongest predictor of protective behavioral intention in intra-urban driving. Sometimes, performing a behavior necessitates the acquisition of skills that a person lacks, and increasing perceived behavioral control can lead to improved driving skills. Therefore, TPB offers an effective theoretical framework for increasing the efficacy of traffic accident prevention initiatives.

Introduction: The present study aimed to investigate the effect of positive thinking skills training based on the Theory of Planned Behavior (TPB) on nurses' resilience during the COVID-19 pandemic in the year 1400.
Methods: The current research is a semi-experimental interventional study with a pre-test and post-test design, the statistical population of which was made up of nurses working in the hospitals of Abadeh and Euclid cities in Fars province in 1400. Based on the inclusion criteria, 98 nurses were selected and randomly divided into two intervention(n=49) and control(n=49) groups. For the intervention, positive thinking training was conducted face-to-face and group discussion in eight 120-minute sessions, twice a week. The duration of training was two months. To collect data, questionnaires of demographic characteristics, Connor and Davidson's resilience and positive thinking were used. Data were analyzed with SPSS software version 26 and using statistical tests.
Results: Based on the findings of this research, the average post-test resilience of nurses in the intervention group (60/02 ± 6/2) was significantly higher than the control group (52/6 ± 3/5). The average positive thinking of nurses in the post-test was 176/6 ± 4/75 and control group (85/04 ± 5/1). Also, after teaching positive thinking skills, the mean resilience score and its dimensions in the intervention group (89/6±3/1) were significantly higher than the control group (53/18±3/6) (P<0/001).
Conclusion: Positive thinking skills training is a safe, low-cost, and practicable approach whose effectiveness was proven in this study. It could, therefore, be widely used as an empowerment program.

It is said that “Graduation marks the end of one era and the beginning of a new one.” Lemire, S. (2023). As for Graduates of the People’s Republic of China, the new means a future employment struggle. As this is one of the most discussed topics in Asia, this comprehensive research study investigates the trials and tribulations involved in the pursuit of work for graduating students in one of the most competitive job markets in the world. Unearthed within this body of work, the team of researchers discovered that a bachelor’s degree is not sufficient even to obtain a first position. Many company recruiters in 2023 now seek postgraduate students instead, due to the intense competition of the recently graduated pool of alumni to apply for first-tier office-oriented positions. In addition to this burdensome or arduous outlook, to find gainful employment. i.e., These graduates have requested higher salaries in the major cities to be proportional to the rising standard of living costs, as recruiters usually offer a standardized lower wage for newcomers at job fairs. Therefore, the psychological effects and ramifications for the new generation in China, have both been delineated and discussed in this paper.

The article presents the results of thermovision tests of the disc brake and the drive system components located in its vicinity on the 111Ed electric locomotive in field conditions. For the mentioned vehicle, the research methodology was developed and the temperature distribution of the brake disc and components and assemblies located in its vicinity during braking was measured. In the article, special attention was paid to the configuration of the thermal imaging camera to the real conditions occurring during the test. This is important because due to the rotating brake disc, it is difficult to verify the temperature value with another contact measuring device. In exceptional situations, temperature measurement using thermocouples is used, but it requires an extensive additional measurement system and signal recording, which is more expensive. Although the thermal imaging camera measures the temperature indirectly, the correct configuration of the camera settings to the real conditions may affect the measurement error by several percent.
