Authors: Iemelianov V. , Ievlev M. , Chubenko O.
Published: February 2023

The monograph is devoted to the study on the basis of the geo-ecosystem approach to the analysis of a large original authors’ and published material of some problems of the relationship between marine geoecology and underwater archaeology as a separate component of the science that studies the history of mankind on the basis of underwater discoveries of material remains of its activities as a cultural heritage. Certain attention is paid to modern geophysical methods and technical means of searching for and identifying underwater objects of the cultural heritage of ancient civilizations, predicting the probability of discovering new underwater archaeological artifacts in the coastal zone of the Northern Black Sea and the adjacent shelf. A brief review of current views on some issues of human evolution as a unique living bio-ecological system and, at the same time, a subsystem of complex global systems – the bio-ecosocio-economic system of mankind and the geo-ecological system of our planet. It is shown that the geological structure, morphology, and dynamics of the geological and ecological subsystem of the geo-ecosystem of the Azov-Black Sea basin, as well as climatic fluctuations in the world and the region of research during the Holocene are the main factors that influenced the formation and functioning of the Black Sea geo-ecological system, and, at the same time, the life and settlement of ancient people in this region, as well as their migration beyond its borders. Without understanding the problems addressed in this monograph, including the definition of ways to solve them, it is impossible to provide any rational organization of effective search, identification, and thorough exploration of components of the system of the regional cultural heritage of the Northern Black Sea coastal part of the geo-ecotone “sea-land”. The authors are hopeful that the data presented in this book will contribute to the development of a national strategy for the systematic development of marine geo-ecological and underwater archaeological research, a better understanding of the importance of ecosystem services, the development of a new synthetic direction of the science of geoarchaeology, which in turn will stimulate the development of tourism industry, including underwater archaeological tourism, the growth of economy not only of the coastal regions of Ukraine but also the country as a whole. For marine geo-ecologists, archaeologists, teachers, students and postgraduates of higher educational institutions, self-government bodies of local coastal communities, government decision-makers, and all those who are interested in the cultural heritage of the ancient Black Sea coast, understand the importance of marine sciences, their achievements for the preservation and improvement of the environment, development of culture and economy of people of the coastal countries and humanity at large.

Ionosat-Micro is a fundamental scientific project devoted to the study of near-Earth space. The project is conceived as an answer to the challenges posed by the modern development of knowledge about Space Weather and the ionospheric responses to surface energy sources (such as weather phenomena, power lines operation, earthquakes and processes of their preparation, powerful technogenic hazards, etc.). Furthermore, the project Ionosat-Micro is a logical continuation and addition to previous ionospheric missions, such as Dynamics Explorer 2 (launched in 1982), Freja (1992), DEMETER (2004), Swarm (2013), and CSES (2018). The project is being prepared with the support and within the framework of The National Space Program of Ukraine and The Program of the National Academy of Sciences of Ukraine for Scientific Space Research. The article outlines the scientific principles of the project, describes the parameters of the space system being created, and the composition and operation logic of the scientific equipment. The project is to be implemented on board the satellite platform Microsat-M, which has been designed by Yuzhnoye State Design Office to conduct scientific and technological experiments. The planned satellite orbit is circular sun-synchronous with an inclination of 98 degrees and altitude of 600–700 km (orbital parameters, method and date of the launch are being clarified). Ionosat-Micro payload includes a set of scientific instruments designed to register the global structure and physical parameters of the neutral atmosphere and plasma, the structure and parameters of the space current systems and geomagnetic field, as well as the spectra and wave-forms of ULF-ELF-VLF electromagnetic perturbations. The Center for Collection, Processing, and Distribution of Measurement Data was created for the purpose of accumulating and targeted data processing.

The study aimed to develop a strategy and methodology for neuroprotection during long-term space missions, which is based on a comprehensive study of the impact of therapeutic hypothermia combined with the action of neuroactive drugs on the key characteristics of synaptic transmission in brain nerve terminals, which change under the influence of planetary dust and conditions of altered gravity. Development of neurotoxicity under conditions of altered gravity may result from excess extracellular glutamate caused by the reverse functioning of glutamate transporters. Under conditions of moderate and deep hypothermia, a gradual decrease in the transporter-mediated release of L-[14C]glutamate from nerve terminals was demonstrated, which is stimulated by plasma membrane depolarization with KCl and dissipation of the proton gradient of synaptic vesicles by the protonophore FCCP. This fact indicates a neuroprotective effect, which increases when hypothermia changes from moderate to deep. The possible risks of using hypothermia in space medicine have been determined. Hypothermia is not able to reduce the extracellular level of L-[14C]glutamate and [3H]GABA, which increases under the conditions of exposure to carbon-containing planetary dust. Hypothermia can lead to a further decrease in the rate of accumulation of neurotransmitters in the presence of carbon-containing planetary dust and to contribute to the development of neurotoxicity, which is a possible risk of using hypothermia in space medicine. In this context, it is important to choose the optimal individual temperature regime for each astronaut.
The effect of polystyrene foam in different doses on the blood parameters and relative mass of internal organs of white mice
Authors: Bilan M. V. , Lieshchova M. A. , Brygadyrenko V. V.
Published: February 2023

Due to their durability, versatility and economy, plastic products are widely used in all spheres of human life. Despite the inertness of polymers, recent studies show the ability of microplastic to overcome natural tissue barriers, accumulate in the animal’s body, affect metabolism and change the intestinal microbiota, negatively affecting it. In a 42-day experiment, changes in the internal organs’ relative mass, blood biochemical and morphological parameters of white mice were established under the influence of different doses of polystyrene foam in their diet. Four groups of white mice consumed crushed polystyrene foam particles (10%, 1% and 0.1% by weight of the feed, control group without the addition of polystyrene foam). At the end of the experiment, the morphofunctional state of the internal organs was determined by the organ mass index and blood biochemical parameters. Adding crushed polystyrene foam to the feed in an amount of 1% causes a significant decrease in the mass index of the heart and stomach, 10% – only the heart, and 0.1% – does not affect this indicator. Polystyrene foam had a significant effect on blood biochemical parameters, regardless of the dose, causing an increase in the activity of aspartate aminotransferase against the background of a decrease in the activity of alkaline phosphatase. The content of total bilirubin, urea, urea nitrogen and cholesterol decreased, and the concentration of creatinine and total protein increased (due to the albumin fraction). The use of crushed polystyrene foam in mice did not cause significant changes in the blood morphological composition, except for a dose-dependent increase in the number of monocytes. In the future, it is planned to determine histological, histochemical and immunohistochemical changes in the organs of laboratory animals under the influence of plastic in a laboratory experiment.

Epistemología del sur y Movimientos Sociales de Abya Yala en Re-existencia territorial
Authors: DUQUINO ROJAS LUIS GABRIEL
Published: February 2023

El presente artículo tiene como objetivo presentar, en el corpus de la epistemología del sur, revisada desde la perspectiva de los pueblos del sur global, una estructura válida para el estudio y entendimiento de los movimientos sociales en re-existencia territorial de Abya Yala. La metodología esta basada en la propia estructura de la epistemología del sur, en las herramientas constituidas por la hermenéutica diatópica, la dialógica crítica y la construcción solidaria del conocimiento. Como resultado se presenta el discurso desde los pueblos originarios en re-existencia como ejercicio de vencimiento de la producción de las ausencias y superación de la epistemología de la ceguera del pensamiento moderno colonial.  En conclusión, se evidencia que, aun cuando los principales enunciados de la epistemología del sur corresponden al mundo académico, este se alimentó principalmente de los saberes-sentires-pensares de los pueblos en re-existencia del Sur Global, y que se hace urgente devolverles esa voz central en los procesos de revalidación y valoración de sus luchas.

Las características físicas, funcionales, cognitivas, afectivas y sociales del fenómeno de la ciudad son interés de la psicología ambiental mediante el estudio de las transacciones entre el entorno sociofísico y la conducta humana. Esta aproximación psicológica al impacto del diseño urbano en las estructuras socioafectivas, culturales y de salud física y psicológica fortalecen el panorama académico y aplicado del urbanismo contemporáneo, al reflexionar sobre propuestas epistemológicas y teórico-metodológicas que analizan las implicaciones psicológicas y emocionales adscritas a los procesos del diseño de la ciudad. De esta manera la enseñanza del urbanismo se beneficia de la trandisciplina al incluir elementos cognitivo-conductuales y emocionales, en el análisis y resolución de conflictos socioespaciales y psicoambientales para coadyuvar a una mejor calidad de vida urbana, mediante propuestas de diseño urbano acordes al mundo real
Consumo de los cuidadores de mascotas del Valle de Aburrá, Colombia, antes, durante y después del aislamiento obligatorio por COVID-19
Authors: Sánchez-Alzate James-Ariel
Published: February 2023

El mercado de productos y servicios para mascotas es uno de los más dinámicos y continúa expandiéndose, incorporando incluso servicios especializados que anteriormente se consideraban exclusivos para los humanos; sin embargo, a medida que el brote de la covid-19 se propaga a nivel mundial con efectos devastadores, no solo en la salud humana, sino en la economía global, dicho mercado parece no presentar cambios gigantescos. Mediante un estudio empírico compuesto por una encuesta aplicada a cuidadores de mascotas del Valle de Aburrá, del departamento de Antioquia en Colombia, se busca identificar cómo fueron los cambios en el consumo de los clientes de este mercado durante y después del aislamiento obligatorio por la pandemia por covid-19, decretado por el Gobierno nacional de Colombia entre el 25 de marzo y 1 de septiembre de 2020, en comparación con aquellos antes de la pandemia. A pesar de que se esperaba un mayor tamaño de muestra, los resultados muestran que el mercado para mascotas es estable, incluso durante el aislamiento. Con lo anterior, se espera que las empresas dedicadas a este nicho lo estudien un poco más a profundidad y puedan generar acciones efectivas y eficientes para lograr aumentar sus ventas, preservando así el desarrollo productivo de la región.
Higher Education Student Complaint Behavior in a Complex Service Ecosystem: A Value Co-creation Perspective
Authors: Zamora-Ramos Moisés Rubén , Díaz-Méndez Montserrat , Chamorro-Mera Antonio
Published: February 2023

During the global covid-19 pandemic, most of higher education institutions (heis) were forced to migrate to an e-learning methodology in order to continue their academic activities. At the same time, the student complaint behavior (scb) increased due to new experiences of dissatisfaction or non-satisfaction. In this context, and seeking to ensure student satisfaction, heis have managed this behavior in the same form that companies do with their customers. Therefore, we present a critical analysis on the generic and standardized approach in the literature and practice to understanding and managing scb in the same way as customer complaint behavior (ccb) is managed. A review of the literature on the theories and studies related to scb and ccb and the student/customer treatment debate are presented, highlighting the complexity of higher education (he) service, which is considered a pillar of development due to its social value. The authors argue the suitable application of the Service-Dominant Logic (sdl), specifically its value co-creation premise, as well as the principles of the Service Ecosystem theory to differentiate scb from ccb. This may allow heis to continue to ensure student satisfaction through the management of their complaints without compromising educational quality and service sustainability. The reflection hereby presented is limited to the Latin America region educational contexts and their structures.

Online Food Shopping: Determinants and Profile of Portuguese Buyers in the Pandemic Context
Authors: Gomes Sofia , Lopes João M. , Oliveira José
Published: February 2023

The covid-19 pandemic brought the opportunity to accelerate the acceptance and usage of existing behaviors and innovations by society and the market. Amongst these innovations, e-commerce food stands out, allowing food companies to redesign their models to face the demand during the pandemic. This research aims to recognize the profile of online food buyers within Portugal and understand the determinants of online food purchase intention in the context of the pandemic. The methodology applied is quantitative, using the Partial Least Squares method to test the hypotheses formulated by the proposed structural model. The data used resulted from applying an online questionnaire to 358 food consumers in Portugal. The results show that situational factors directly related to eating behavior positively impact the online food shopping experience, increasing the intention to purchase food online during covid-19. Concerning the profile of the e-consumer, it seems that owning a vehicle negatively influences the intention to purchase food in e-commerce, as opposed to the level of income, which is a positive factor. On the theoretical side, this research contributes to the literature by contributing on the theme of food e-commerce in a pandemic time, which is currently very scarce. As for practical contributions, through the identification of the trends in consumer behavior during and after the pandemic, companies can better anticipate and prepare for new consumer needs and profiles, consequently developing new strategies and increasing their e-commerce sales. Since Portugal has a small digital population and less than 35% of digital natives, the prominence of studies in this area is minor. The current research is original and innovative, as studies that analyze consumer behavior in food e-commerce in this country, specifically during a pandemic, are scarcer.

Trazando nuevas rutas en común: un estado del arte de las alianzas para el desarrollo sostenible
Authors: Rodríguez Cotilla Montserrat
Published: February 2023

Existen retos para lograr el desarrollo sostenible que no pueden ser abordados de manera aislada y donde colaboran diversos actores del sector público y privado. En los últimos años ha surgido mayor interés en el tema sobre las alianzas multisector, sin tener una definición establecida sobre el concepto o sobre quiénes son los actores que forman parte de las colaboraciones. La investigación se elabora mediante una revisión de literatura de la noción de alianzas para el desarrollo sostenible con el fin de identificar conceptos, actores involucrados, roles de los actores y sus características, así como las aportaciones dentro de las alianzas mediante un enfoque descriptivo. Los datos se recolectaron en el buscador de Scopus, encontrando 464 resultados de 1.179 diferentes autores con los términos “sustainable development” AND “partnerships”, y una segunda búsqueda en literatura gris con los mismos conceptos entre el 2010 y el 2020. Finalmente, se presenta un análisis de los seis términos más relevantes alrededor del concepto, así como de los actores y los roles dentro de las colaboraciones. Asimismo, se aborda la necesidad de futuras líneas de investigación en modelos de gobernanza, gestión y efectividad de las alianzas para lograr el desarrollo sostenible.

Authors: Quevedo Alejos María Isabel Alejandra , Chong León Esteban
Published: February 2023

Las normas contables vigentes no permiten a la contabilidad brindar toda la información sobre los intangibles que representan fuentes de creación de valor y ventaja competitiva para las empresas. Debido a su importancia, la divulgación de los intangibles es necesaria para comprender la situación integral de una empresa. Estos intangibles conforman el capital intelectual, siendo uno de sus elementos el capital estructural. El objetivo del presente estudio es analizar la divulgación sobre los intangibles relacionados con el capital estructural de las empresas del sector financiero de Perú inscritas en la Bolsa de Valores de Lima (bvl), y los factores que influyen en tal divulgación. Con este propósito, se analizaron las memorias anuales de 55 empresas del sector financiero peruano, utilizando 42 indicadores y aplicando el modelo Probit, con lo que se obtuvo como resultado que dichas empresas divulgan mayor información relacionada con el capital estructural organizativo que con el tecnológico, siendo el tamaño, la rentabilidad y el crecimiento los factores que influyen en su divulgación. El estudio se limita al sector financiero y a un elemento del capital intelectual, por lo que sería importante realizar el estudio en otros sectores, así como la divulgación de los demás intangibles que conforman el capital intelectual.

Authors: Cea Rodríguez Jorge , Medina Francisco J. , Ramírez-Marín Jimena
Published: February 2023

Este artículo pretende describir la eficacia de los comportamientos de mediadores laborales en conflictos colectivos chilenos, a la vez que da cuenta del funcionamiento del sistema de mediación laboral en Chile. Se realizaron 19 entrevistas a mediadores chilenos de cinco centros de mediación distribuidos por todo el país, utilizando como base el cuestionario sobre mediadores exitosos propuesto por Goldberg (2005). Las autodescripciones se analizaron con el software ATLAS.ti 9.0, a partir del cual se trabajó con el sistema de categorías de estrategias de mediación propuesto para desarrollar una buena relación con las partes a través de la empatía, la confianza, la neutralidad y la escucha activa. Los mediadores laborales reportaron el uso de dos tipos de estrategias (contextual y reflexiva) y no dieron cuenta del uso de estrategias sustantivas. Los resultados fueron consistentes con algunos hallazgos en la literatura según los cuales los mediadores mostraron que la razón central de su éxito fue dado por el uso de estrategias contextuales y reflexivas, no habiendo distinción respecto de las estrategias en los distintos tipos de conflictos.
Liderazgo ético: su relación con los conflictos, la confianza y la transferencia de conocimiento
Authors: Vargas-Salgado María Marisela , Máynez-Guaderrama Aurora Irma , Gómez-Bull Karla Gabriela
Published: February 2023

Los líderes éticos son ejemplo de conducta con el que los empleados se identifican y tratan de emular. El interés en este estilo de liderazgo creció fuertemente en la primera década del siglo, pero aun cuando se reconoce su importancia son escasos los estudios empíricos para comprender sus relaciones con otras variables. El propósito de este trabajo es indagar en la influencia del liderazgo ético sobre los conflictos, la confianza y la transferencia de conocimiento en el entorno de la industria maquiladora de exportación, sector industrial relevante para la economía fronteriza norte de México. Para ello, se utilizó un diseño de investigación cuantitativo, no experimental, transversal, descriptivo y correlacional, con una muestra no probabilística por conveniencia. La técnica estadística fue un modelo de ecuaciones estructurales pls. Los resultados indican que el liderazgo ético y la confianza inciden favorablemente sobre la transferencia de conocimiento, los conflictos no inciden sobre la transferencia de conocimiento, y el liderazgo ético no impacta en los conflictos. Estos hallazgos evidencian beneficios del liderazgo ético, en este caso asociados a la confianza y a la transferencia de conocimiento, y destacan que el liderazgo ético implica la justicia y la objetividad en el trato con los miembros del equipo de trabajo, incluso cuando ello pueda resultar difícil o complejo.

Authors: Hualpa Zúñiga Andrés Mauricio , Rangel Díaz Jorge Eliécer
Published: February 2023

Introducción. La trazabilidad se considera en los sistemas empresariales como una herramienta de seguimiento y control enfocada en la medición y recolección de datos para la asignación eficiente de recursos. El sector agrícola no es ajeno a esta práctica porque al igual que otros sistemas industriales, integra necesidades de control a nivel de cultivo, abastecimiento de insumos, transformación, transporte y comercialización de productos. Objetivo. Identificar objetos y alcances de seguimiento, unidades de análisis y adopción de tendencias de trazabilidad en la cadena de suministro agrícola, para referenciar el desarrollo de estudios y publicaciones recientes que integran esta función de control en este sector. Desarrollo. La metodología aplicada se desarrolló a través de la búsqueda, selección y análisis de artículos en repositorios científicos como Science Direct y AGRIS, para identificar tendencias de trazabilidad agrícola en los años 2017 al 2022. Se reconocieron tendencias de aplicación e integración de los sistemas de trazabilidad en el sector agrícola entorno a distintos enfoques, entre ellos, la digitalización y seguridad de la información, la medición de la productividad agrícola y el impacto ambiental dentro del concepto de sostenibilidad. Se presentan en las conclusiones las líneas de investigación, así como las brechas de conocimiento para futuros trabajos. Conclusiones. Los resultados de la revisión en los últimos seis años enmarcan tendencias de trazabilidad en el seguimiento digital de procesos de cultivo, la medición de la productividad y el impacto ambiental. El grado de intervención directa en el productor representa la mayor proporción en la categoría del alcance logístico de trazabilidad. Por lo anterior, se recomienda a futuro el desarrollo de sistemas de trazabilidad que realicen seguimiento de indicadores de productividad, impacto ambiental y social de manera convergente, así como la participación integrada de actores del sector agrícola, entre ellos productores, asesores técnicos y entidades gubernamentales.
Effect of irrigation and fertiliser doses on sweet corn yield, water consumption and water utilization
Authors: Szalókiné Zima Ildikó
Published: February 2023

The experiment was conducted within a framework of a two-factor long-term trial at the Research Institute for Fisheries, Aquaculture and Irrigation, in Szarvas, Hungary. This was a special field experiment, in which lysimeters have been installed in the middle of 32 m2 field plots. The main factor was the water supply with 4 levels: i1: non-irrigated control; i2: irrigated with one third of the optimal water supply; i3: irrigated with two thirds of the optimal water supply; i4: optimum irrigated plot, according to the requirement of sweet corn test plant. The amount of released irrigation water was 0, 54, 106 and 158 mm per year on average over 5 years. Within every water supply treatment there were 4 nutrient supply rates (N): N1, N2, N3, N4 = 100, 200, 300 and 400 kg ha−1 NPK fertiliser substance in ratio 2:1:1. The number of replications was 4, and the experiment was arranged in split-plot design. In the studied years, the amount of precipitation varied between 92 and 264 mm from sowing to harvesting.

The effect of fertiliser was less in the non-irrigated treatments compared to that of the irrigated ones, and the yield was increased only up to 200 kg ha−1 NPK treatment level. The NPK dose of 300 kg ha−1 proved to be optimal in the irrigated treatments in which the utilization of fertilizer doses increased parallel to the improving water supply. In addition, the ratio of first class products (cobs longer than 20 cm) increased to a greater extent than the yield as a result of irrigation and fertilization. Water requirement of sweet corn proved to be between 400–450 mm resulting in an average yield of 20–24 t ha−1, of which 18–20 t ha−1 came from marketable cobs. The amount of evapotranspiration fluctuated between 270–440 mm during the five years, depending on the quantity of water supply, but it changed to a lesser extent than the amount of the yield. Increasing the fertilizer dose practically did not affect ET in non-irrigated plants, but increased it by 20–30 mm in irrigated ones. The change was not significant.

The productivity of ET was only 30–45 kg ha−1 mm−1 in the non-irrigated treatment, while it was 50–55 kg ha−1 mm−1 in the irrigated treatments, with higher values at the higher fertiliser rates. The productivity of irrigation water exceeded far over the productivity of ET at adequate nutrient supply. The yield increase per 1 mm of irrigation water was on average 60 kg ha−1 mm−1, which was considerably higher than the productivity of ET of non-irrigated plants (39 kg ha−1 mm−1). There was a positive correlation between the yield and ET, and a negative correlation between the yield and specific water consumption. Irrigation and fertilization increased the average yield to a greater extent than evapotranspiration, so as the average yield increased, the ET per unit of yield decreased, i.e. the productivity of evapotranspirated water increased.

Published: February 2023

The high demand for COVID-19 diagnosis overwhelmed reference hospitals. Regional laboratories had to incorporate molecular technology to respond to the emergency. This work described the implementation of molecular diagnostic tools and the detection of SARS-CoV-2, in a regional hospital with no previous experience, from October 2020 to March 2022. The laboratory structure was significantly modified. The staff grew from 3 to 4 clinical microbiologists, and from 7 to 17 laboratory technicians to provide 24/7 coverage. A total of 144,442 samples were processed during the period of study. The highest peaks were reached in July 2021 with 25,285 samples processed, and between December 2021 and January 2022, with 32,245. COVID-19 pandemic has represented not only the challenge, but the opportunity to introduce Nucleic Acid Amplification Techniques (NAAT) in inexperienced laboratories. These secondary settings have shown an extraordinary ability to adapt and cannot be left behind in the progress of diagnostic techniques.

Nowadays, especially young people, cannot imagine the world without modern technologies. Thanks to them they can do practically everything they want without leaving home (even things that are not entirely legal). However, this attachment to the digital world carries a number of risks. Children and young people, because of their attachment to devices, online relationships and often recklessness, can become easy targets for criminals in cyberspace. They may also become perpetrators due to the illusory anonymity in the network. For this reason, the author has attempted to take a deeper look at the phenomenon of cybercrime among minors by presenting, among other things, its scale.

ALGORITHMS FOR SEARCHING FOR AN ACCEPTABLE OPERATING MODE OF A CABLE CHANNEL BASED ON AN ASSESSMENT OF ITS TEMPERATURE STATE
Authors: Kukharchuk I. B
Published: February 2023

The great majority of currently used cable products contain polymer materials in their construction, which tend to degrade their physical and electrical properties over time. This process is aggravated when the temperature of the product increases. The design of cable lines and the conditions of their collective laying, for example, in cable channels, complicate the thermal control of their operation, while the conditions of an isolated channel contribute to the heating of individual lines at the expense of neighboring ones. The existing engineering methods for calculating the cable temperature specified in IEC 60287-1-1-2009 do not allow taking into account all the features of a particular cable structure. Therefore, the task of a quick and accurate assessment of the thermal state of all polymer elements of the lines laid in the channel is very urgent. The paper considers the possibility of replacing direct observation of the thermal field of a cable channel with its equivalent mathematical model capable of determining stable stationary temperature distributions at given current loads of lines. Such a model, in addition to the speed of finding the desired parameters, has such an advantage over a real line as the ability to evaluate the internal temperature field of the cable without violating the integrity of its design. Using a mathematical model, it is proposed to analyze the thermal state of the channel by comparing the temperatures of the elements of cable lines with a predetermined setpoint. When the fact of exceeding the setpoint is detected, an algorithm is started for selecting such a combination of current loads at which the temperatures of the line elements do not exceed the set value. An additional criterion for selecting the mode is the minimum reduction of currents in comparison with their initial value. The algorithms proposed in this paper are universal and can be used for channels of various designs and with different numbers of lines, as well as for analyzing the operation of similar engineering structures, for example, ventilation ducts with transit lines of air conditioning systems, pipelines for hot liquids and gases. The developed algorithms are functionally suitable for creating specialized software operating in the mode of an adviser to the operator of an electricity distribution node. The software is designed to pre-evaluate any change in line loads, checking for possible overheating and giving the operator either approval of the mode, or offering a safe option for long-term operation.

The Congregation of Sisters Carmelites of Baby Jesus was founded on 31 December, 1921 in Cracow by Father Anselm from St. Andrew Corsini OCD (Maciej Józef Gądek 1884–1969) with Janina Kierocinska’s participation (later: Mother Theresa from St. Józef). On the same day when the new community came to Sosnowiec, it started its activity in Christian Charity Organization, at the church Of Sacred Heart of Lord Jesus. The stabilization of the congregation was followed by its settlement in a house at Wiejska 25 in Sosnowiec (14 September, 1925). The religious house in Sosnowiec at Wiejska 25 was the place in which life of the convent was concentrated. The house was a seat of the general management (1925–1967), the noviciate (1925–1969), and also the place where the main directions of the activity of the institute developed. Within the convent which was patronized by St. Theresa from Baby Jesus, the charisma of the convent was shaped. Sisters who lived in the house in Sosnowiec led wide and various apostolic activities: educational-protective, charitable, and catechistic.

This article aims to provide researchers unknown diaries from the time of the January Uprising. Within this framework, we will discuss their content and will try to identify the people who signed up to them. We will also take a closer look at the circumstances in which one of them went to the Toruń library. Research method: Analysis of manuscripts and review of the literature. Results/Conclusions: The namesakes presented are interesting souvenirs after the participation of Poles from the Prussian partition in the January Uprising. The fact that they were kept in the Hausvogtei detention facility in Berlin testifies to the level of freedom in the Prussian penitentiary system. They can be an excellent source for research on the specificity of prison life, and in exceptional circumstances, which was the show trial in 1864.

Aim. To develop a program for early physical rehabilitation of inpatients after heart valve surgery and to evaluate its effectiveness and safety.

Material and methods. The study included 80 patients with valvular heart disease (VHD) after elective on pump valve surgery. Patients in the control group (n=47) underwent standard cardiac rehabilitation after surgery; patients of the main group (n=33) additionally, starting from the 8th day after the intervention, had 14-day treadmill training with the program selection, taking into account the results of cycle ergometry spirometry (CES). A week after the operation and at the end of the training course (median, 24 days after the operation), cardiac remodeling and functional status was assessed according to echocardiography and CE, respectively.

Results. For 7 days after surgery, patients of both groups were comparable. During physical training in the main group, there were no lifethreatening cardiac arrhythmias, episodes of ischemia, desaturation, as well as intracardiac hemodynamics deterioration. With a 14-day training, CES showed a significant increase in exercise tolerance (ET) in the main group from a median of 50 to 75 W (p=0,002), peak oxygen uptake (VO2peak) from 11,7 to 13,4 ml/kg/min (p=0,001). For 24 days after surgery in the control group, there was a trend towards improvement in ET and VO2peak, but without significant changes (p=0,09/p=0,08).

Conclusion. Early inhospital rehabilitation, including physical training of moderate intensity with an individual treadmill speed and incline angle, starting from day 8 after surgery, showed effectiveness and safety in the form of an increase in ET and VO2peak, while not worsening hemodynamic parameters.
Residual risk in patients with atherosclerotic cardiovascular disease

The residual risk in patients with atherosclerosis, despite the its controversial aspects, remains an urgent problem of modern cardiology. The article presents a review of publications on the prevalence and significance for determining the prognosis of residual risk, which is currently interpreted as the risk of macroand microvascular complications in patients with atherosclerotic cardiovascular disease (ACVD) taking standard therapy, with the achievement of optimal levels of low-density lipoprotein cholesterol, blood pressure and glucose. Based on available publications, we highlighted current views on the factors associated with residual inflammatory and lipid risks in ACVD patients, including those associated with heart failure and diabetes, and the prognostic significance of residual risk in such patients. An attempt was made to rationale the significance of determining the residual risk for secondary prevention of cardiovascular events.

Anticoagulants are widely used in clinical practice to reduce the risk of cardiovascular events. However, there are associated clinical conditions that require coagulation system monitoring due to an increased risk of bleeding. In clinical practice, cases of warfarin hypersensitivity due to gene polymorphisms are known. Taking warfarin in such a situation is often manifested by massive bleeding that threatens the patient's life. Sixty seven-years-old female patient was admitted to the internal medicine department of Rostov State Medical University clinic in March 2022. The day before, she noted severe abdominal pain, loose bloody stool. An outpatient examination revealed an increase in international normalized ratio to 9,42, thrombin time >30 sec. There were no signs of primary gastrointestinal pathology. According to anamnesis, on January 21, 2022, the patient underwent mechanical aortic valve replacement, in connection with which warfarin was prescribed at a dose of 2,5 mg/day. After establishing hypocoagulation, warfarin was discontinued. A pharmacogenetic analysis was performed, which established the carriage of polymorphisms of cytochrome P450 system genes, the homozygous mutation 1075A>C (CYP2C9 (*3/*3)), and the heterozygous mutation of the vitamin K reductase gene VKORC1 G(-1639)A (VKORC1 GA). The individual dosage of warfarin was calculated according to International Warfarin Pharmacogenetics Consortium guidelines, which was 9 mg/week. After adjusting the dose of warfarin, the level of international normalized ratio decreased to 3,61, thrombin time to 13 sec. The patient was discharged with recommendations to follow an individual warfarin regimen and monitor coagulation parameters. The presence of hypersensitivity to warfarin is not a reason for its complete withdrawal in situations requiring longterm anticoagulation. In this regard, it is necessary for the doctor to be vigilant when prescribing warfarin to a patient, understanding the causes and methods for diagnosing hypersensitivity to warfarin, and timely correction of its dosage.
