The Rusin “Robin Hood” - Andrij Savka
Authors:   Institute of Philosophy and Law of the Ural Branch of the Russian Academy of Sciences, Korsakov Konstantin V.
Published: February 2023

This article is devoted to Andrij Savka, a famous Rusin (Lemko) garnas - the leader of the Beskidniks (opryshki) robber detachment, a well-known leader of the insurrectionary and people's liberation movement in southern Poland and a hero of Eastern European folklore from Dukla (Poland). This valuable collection of little-known biographical information about this iconic figure focuses on the reasons why Savka became a robber, organized his own gang (Bursa) in the Beskydy Mountains and subsequently joined the Podhale Peasant Uprising of 1651 with his illustrious squad under the leadership of the Polish officer Aleksander Leon Kostka-Napierski. The main reason was the strong feudal oppression by the local Polish gentry, which forced the Rusin peasants to defend their interests, rights, and freedoms with deadly force, to fight against national and religious discrimination, serfdom, and oppression. The author emphasizes that Savka acted not in his personal and selfish interests, but out of a desire to help the commons. He distributed the property seized from magnates, landlords, and priests to poor Rusin peasants, for which he was dubbed as “Lemko Robin Hood”. The article thoroughly examines the significant role played by Savka and other famous Lemko rebels - Vasil Bayus and Vasil Chepets - in the people's liberation struggle that unfolded in Lesser Poland, Galicia and Subcarpathia and was supported by Hetman Bohdan Khmelnytsky and his associates. The author highlights the reasons why the Podhale Peasant Uprising of 1651 failed, with its leaders captured and put to death. He concludes that Savka played a progressive role in the history of the Rusins, in which he epitomizes courage and determination in the struggle for freedom and justice.
The Ukrainian professional associations of teachers of Galicia and Bukovyna (second half of the 19th - early 20th century): an attempt of comparative analysis

Published: February 2023

Focusing on the professional teachers' associations of Galicia and Bukovyna, the author makes an attempt of comparative analysis and introduces a number of previously unknown sources to discuss six professional pedagogical associations established during the 1880s - early 20th century. The problems of public schools and proper professional level of their teachers came in sight of “Rus Pedagogical Society” (“Ukrainian Pedagogical Society”) in Galicia and the “Ruska Shkola” (“Ukrainian school”) in Bukovyna. “Mutual Aid of Ukrainian Teachers” and “Free Organization of Ukrainian Teachers in Bukovyna” defended the professional interests of school teachers respectively. Higher professional level of gymnasium teachers in Ukraine became a priority in the activities of the “Teachers' Community” and the Hryhoriy Skovoroda Society of Higher School Teachers established in Lviv and Chernivtsi. Since Galicia and Bukovyna were separate autonomous regions within Austria-Hungary, they had their own teachers' associations with the similar mission. The difficulties faced by the schools of these two regions were similar; however, they tackled them differently due to the specific political circumstances. As a result, the Ukrainian Pedagogical Society in Galicia had the most significant achievements in the creation of the Ukrainian-Language primary schools, gymnasiums, teachers' seminaries, courses for the illiterate and publishing activity, while the pedagogical assiciations of Bukovyna managed to protect the professional rights of teachers and achieve a significant increase in teachers' salaries supported by other public associations and political parties of the region.
Siberian-Polish history in the journals Sybirak and Katorga i ssylka
Authors:   Tomsk State University, Nam Iraida V.
Published: February 2023

The article focuses on what the Moscow journal Katorga issylka and Warsaw journal Sibiryak published about the Polish exile to Siberia in the interwar period. The issues of hard labour and exile to Siberia have been central in both periodicals. Sibiryak was published in 1934-1939 by the Union of Siberians, founded in 1926-1927 by the Poles who returned from Russia. They were former exiles and prisoners of war. These materials contributed to the identification and collection of the information about the Siberian Polish history and to the consolidation the “Black Legend” about the Polish exile to Siberia, formed by the memoir tradition of the 19th century. The journal published articles, memories and other materials related to the participants in the Polish uprising in 1863-1864, subsequently exiled to Siberia. Katorga issyikawas published in 1921-1935 by All-Union Society of Former Political Prisoners and Exiled Settlers. The main sections of the journal published on the revolutionary movement history in the Russian Empire, together with obituaries, bibliography, and chronicles. The questions of Polish exile to Siberia and participation of the exiled in the revolutionary movement were among the topics discussed by this journal, too. However, it published much less on the discussed problem if compared to what was published in Sibiryak. The publication started the historiographical tradition of considering the issue of Polish political exile to Siberia in the broad context of the revolutionary movement history in Russia and the formation of Russian Polish revolutionary ties.
Russian students in Tomsk University and the national policy of late Imperial Russia
Authors:   Tomsk State University, Stepnov Aleksei O. , Nekrylov Sergei A. ,   Tomsk State University
Published: February 2023

The article examines the process of intellectual colonization in Russian Siberia in the late 19th - early 20th centuries. A nuanced approach to the national policy repertoire of the late imperial Russia allows tracing how similar political actions caused different effects on the western and eastern outskirts of the empire. The Russian majority of the student body formed at the Imperial Tomsk University (further referred to as ITU) in the late 1880s, when the trustee of the West Siberian Educational District Vasily Florinsky proposed to enroll graduates of Orthodox theological seminaries. This method was also used to russianize Warsaw and Yuriev (Derpt) Universities. However, this decision, initiated in relation to ITU, did not meet with unanimity in the ruling circles, since there were planty of radical leftists among the clergy students, who championed an autonomous Little Russian self-consciousness and became activists of the Ukrainian Students Zemlyachestvo during 1909-1910. The admission of seminarians to universities in the western outskirts of the empire, which, unlike Siberia, were never destined to become Russian, had similar consequences. However, the strategic effects of these manipulations differed. It is assumed that the radicalism of ITU students was often exaggerated. The conspiracy interpretations of their activity in historical sources are explained by the atmosphere of distrust and confrontation between the ITU professors, the trustees of the West Siberian Educational District, and the Ministry of National Education. However, the consequences of FLorinsky's project implementation manifested themselves over a long historical distance, when the educated class of Russians, who graduated from ITU, dispersed across Siberia. It was Florinsky's strategic aim, since he believed that the future of Siberia as a “flourishing Russian province” was guaranteed not so much by the mechanical migration of Russians to the east, as by the expanding cultural hegemony of the Russian nation.
Russian right-wing conservative periodical press about Rusins at the beginning of WWI
Authors:   St. Petersburg State Electrotechnical University ", Stogov Dmitrii I. ,   LETI",   named after V.I. Ulyanov (Lenin)
Published: February 2023

Now, when the spiritual unity of the Slavic world is undergoing another test of strength, it seems relevant to appeal to the rich historical experience of the relationship of the Slavic peoples. Of particular interest are plots associated with turning points in history, in particular the First World War, when the fate of the Slavic peoples was decided on the battlefields. In this article, the author turns to the Russian right-wing conservative press at the initial stage of the First World War to study the Rusin question. According to him, Russian right-wing conservative publicists showed a genuine interest in the life of Rusins in Eastern Galicia and Bukovina, occupied by Russian troops in 1914. Such periodicals as Groza, Pochaevskiy listok, Susanin, Moskovskie Vedomosti, Russkoe znamya, Kolokol, Zemshchyna covered the following subjects: the history and culture of Rusins, their religious and socio-political life, the Rusin-Polish and Rusin-Austrian relations, attitude to “Ukrainism”, the life of Rusins after the capture of Eastern Galicia and Bukovina by Russian troops, the future of Rusins as part of the Russian Empire. The author concludes that almost all above-mentioned right-wing conservative publications agreed on the perniciousness of “Ukrainianism”, which became widespread in Galicia supported by Polish magnates, as well as on the need for Rusins to transit from Uniatism to Orthodoxy. They also emphasized that the annexation of Galicia and Bukovina had a positive effect on Rusins, the majority of whom were in favor of reunification with Russia.
Efecto de un programa de intervención en alumnos con desempeño ortográfico descendido
Authors: Palombo Ana Laura , Cuadro Ariel
Published: February 2023

El principal objetivo de este estudio es analizar el efecto, a partir de pruebas estandarizadas, de un plan de intervención en ortografía para alumnos con buen nivel lector y rendimiento descendido en ortografía. El diseño del programa toma como referencia el realizado por Sampaio y Capellini, (2015) y se realiza en base a una práctica sistemática y acotada en el tiempo, con grupos a priori y considerando palabras de ortografía consistente, dependiente del contexto e inconsistentes basadas en la frecuencia de uso. La muestra está conformada por 54 escolares de 3ro a 6to grado de nivel primario pertenecientes a un centro educativo de contexto favorable de Montevideo. Los resultados indican que las palabras de ortografía directa y dependiente del contexto obtuvieron diferencias significativas entre el grupo experimental y el grupo control, no encontrándose diferencias en el grupo de palabras inconsistentes. El estudio deja en evidencia que la ortografía es sensible a la instrucción sistemática y programada; así como el uso limitado de las pruebas estandarizadas para evaluar la mejora en ortografía de palabras inconsistentes.
Desigualdades e injusticias: reproducciones y resistencias en educación
Authors: Guido-Guevara Sandra , Soler-Martín Carolina
Published: February 2023

El presente artículo de reflexión se elaboró a partir de diálogos entre dos grupos de investigación a propósito de algunas indagaciones recientes que coinciden en la relevancia de visibilizar injusticias y desigualdades en ámbitos educativos derivadas de construcciones sociales sobre las diferencias humanas y, también, concuerdan en el reconocimiento de praxis que resisten y provocan giros y transformaciones en sus micro contextos pues trabajan por una educación y un mundo menos injustos. El artículo se compone de cuatro momentos: el primero, acercamientos a las nociones de desigualdades y de injusticias sociales; el segundo, una vista desde el aire a partir de estudios que brindan un panorama macrosocial de factores y datos que conllevan a comprender desigualdades e injusticias en educación desde las brechas entre sectores poblacionales, como categorías ordenadoras se recurrió a las 4 propuestas para el seguimiento al cumplimiento del derecho a la educación. El tercer momento presenta una vista desde el suelo o desde estudios en terreno de las praxis educativas realizados con perspectiva sociocrítica y de epistemologías del sur que desentrañan realidades de las desigualdades y las injusticias comprendidas desde las categorías del colonialismo, el patriarcalismo y el capitalismo. Por último, se analizan algunas praxis educativas que sujetos individuales o colectivos gestan en sus escenarios educativos y que pretenden resistirse a relaciones asimétricas, exclusiones y violencias que derivan en injusticias.
La práctica pedagógica: consideraciones críticas a propósito de las pruebas Saber Pro para licenciados
Authors: Cuesta-Moreno Óscar Julián , Reyes-Galindo Rafael
Published: February 2023

Este artículo analiza los enunciados sobre enseñanza, formación y evaluación presentes en estas guías y documentos del Marco de Referencia para las Ciencias de la Educación para la prueba Saber Pro, que presentan los profesores en formación. Resultado del análisis, se evidencia que estos conceptos son abordados de manera limitada en estos documentos pero, sobre todo, que desplazan el saber pedagógico a un lugar menor. De allí que el texto brinde conceptualizaciones pedagógicas para la enseñanza, la formación y la evaluación, haciendo una defensa explícita por la pedagogía como campo conceptual y, en esa línea, reivindicando el reconocimiento social del profesor. Consecuentemente, el artículo argumenta que la práctica pedagógica permite la reivindicación del maestro, pero sobre todo es una herramienta epistemológica clave para la formación de los licenciados.

En este proceso, resaltamos los servicios culturales, provisión (aprovisionamiento), soporte y regulación, registrados en la imagen y en la voz colectiva. Discutimos dos principales ventajas con el uso de la fotografía. Primero, que puede ser utilizada para evocar reflexiones, considerando la imagen como centro de discusión; segundo, los participantes pueden registrar fotografías de manera inmediata usando los teléfonos móviles. De este modo, exploramos las posibilidades emergentes de la creación fotográfica, y su potencial para visibilizar diversos aspectos ambientales. La metodología incluyó un taller de fotografía participativa donde colaboraron 16 personas con 120 fotografías registradas; en colectivo seleccionamos 30 imágenes, y discutimos sobre los contrastes y significados asignados. Los discursos fueron registrados, grabados y sistematizados con previa autorización (consentimiento por escrito). Utilizamos análisis temático, desde un enfoque interpretativo, y codificamos los contenidos partiendo de los servicios ecosistémicos. En los resultados, destacamos cuatro aspectos relevantes, 1. La afinidad con los servicios ecosistémicos culturales, 2. La valoración de se a partir de heterogeneidad social, 3. El sentido de pertenencia e identidad con el territorio habitado, y 4. La sinergia entre la creación fotográfica y la educación eco ciudadana. Mostramos tendencias, y contrastes en las fotografías, y resaltamos los significados en fragmentos textuales de relevancia.

Authors: Garcés-Montoya Ángela , Acosta-Valencia Gladys Lucía
Published: February 2023

Este artículo, producto de la investigación Territorios Sonoros: escuelas Hip Hop en Medellín, se propone caracterizar las dinámicas de agrupación, las prácticas, los discursos y los procesos educativos en la ruta del arte urbano en el caso de las dos escuelas de rap, objeto de este trabajo. El rap, reconocido como uno de los géneros musicales que configura territorios sonoros en las periferias de Medellín, tiene una trayectoria de más de 30 años de expresión y apropiación de espacios sociales comunitarios. Son numerosos los estudios del movimiento hip hop en América Latina, sin embargo, son recientes y escasos los estudios que exploran la escuela, como quinto elemento que se suma a los cuatro que han sido tradición en el género. En el contexto de la Educación Social y las reflexiones en torno a los procesos educativos y sus posibilidades disruptivas, con un enfoque en diálogo de saberes, se trabajó con una muestra constituida por dos escuelas de arte urbano: AgroArte: Hip Hop Agrario y Escuela Feminista. Se utilizaron técnicas propias de la etnografía urbana: taller de memoria, entrevista grupal y relatos de experiencia. Entre los hallazgos se cuenta la identificación de procesos educativos que, en sus dimensiones estética y política, logran producir prácticas, discursos, saberes, modos de relacionamiento, vínculos con el territorio y con la memoria que están generando transformación en sectores de periferia de Medellín, las cuales se evidencian en la cotidianidad de los territorios y en la constitución de unas subjetividades emancipadas, que le apuestan a la creación colectiva y a la resistencia cultural.
challenges of the metadata infrastructure for digital works and the role of cultural policy
Authors: Lefever Nathalie
Published: February 2023

While digitalization has opened up new opportunities for disseminating creative contents, issues related to the management of metadata (data to identify works and authors) impact the capacity of creators to obtain fair copyright-based remuneration. The reasons for incomplete or incorrect metadata are the lack of properly assigned metadata, of interoperability, and of  authoritative sources. This creates difficulties in the distribution of revenue to creators, editors and other rightholders, missed licensing opportunities and recognition for authors, as well as increased risks of unauthorized use. As problems of metadata directly impact digital creation, digital distribution and access to creative works, cultural policy has a role to play in their resolution. Any long-term and efficient solution will require the support of the artistic community. For these reasons, the issuesrelated to metadata and the data infrastructure around creative works should also be discussed in the context of cultural policy.

The friction stir welding (FSW) is widely used in the fabrication of Aluminium alloy and other non-ferrous alloy. It has good potential to be used in major industries such as automobiles, aerospace, shipbuilding and can be used in the joining of high strength alloys. The FSW process low distortion and heat affected zone (HAZ) with fine recrystallized microstructure which leads to better mechanical properties at the weld zone and produces great stability. In this study, the different FSW parameters such as weld speed, tool rotation speed, tool tilt angle, feed per min has been discussed. The different types of tool pin profile and shoulder have also been discussed and their impacts on mechanical and microstructural properties at welded joints. Among various welding parameters the rotational speed is the most influencing parameter in FSW. Increasing the rotational speed exhibits the increase at tensile strength and is supposed to improve the mechanical properties. The most affected tool pin profile would be considered to be tapered threaded cylindrical pin profile which makes the adequate mixing of material with better flow ability and provide the fine grains at nugget zone. Comparing the FSW with other arc welding processes, it shows a wide range of environmental benefits which are noticeable such as saving in consumable materials, decrease in consumption of filler material and reduction in grinding wastes. Harmful emissions created from arc welding causes a health hazard to the welder. For achieving the high joint-strength for aerospace aluminium alloys and high temperature sustainable metallic alloys, friction stir welding will be preferred.

Driving vehicles has become more complex. Thus, drivers who are not engaged with any non-related driving activities, that is performing in-vehicle secondary task, are unusual nowadays. Statistics also shows the higher number of crashes come from distracted driving. In addition, currently, there is limited review have been done to compile and review the physiological method, driving distraction and its effect on the driver. Therefore, this paper aims to review the effect of driver’s in-vehicle distraction and secondary task during driving on driver’s health and safety. A systematic search was conducted on the basis of the preferred reporting items for systematic reviews by using PRISMA guidelines. Any criteria were imposed for the included sample. The search was focused on in-vehicle secondary task and distraction. Results showed that 21 articles investigated the major ability for in-vehicle secondary task distraction using physiological measures. Findings showed a significant effect of the in-vehicle secondary task and distraction on driver’s condition. Drivers’ characteristics such as their experience and age are also factors in determining the effect of distraction and secondary tasks on their condition. However, further studies are needed to understand the physiological effect of secondary task on young driver’s condition due to the relatively higher number of crash rates from those at a young age.

The solid oxide fuel cell (SOFC) is a promising technology with specific characteristics for generating electricity by using hydrogen and oxidant as fuel. Typically, SOFC’s use Samarium doped Ceria (SDC) as an electrolyte material as the ionic conductivity of SDC was better at lower operating temperatures which are below than 700°C that making it a good option for low and moderate temperature applications for SOFC. However, SDC electrolytes are cannot be densified below 1500°C. If a densified ceria-based electrolyte can be prepared at lower temperatures it can be co-sintered with another electrode component. This simplifies the fabrication process and reduces the cost. Other than that, it can help with porous electrode microstructure control and avoiding phase diffusion and chemical interaction problems. As a result, decreasing the sintering temperature may be another step toward commercialising SOFC technology. The modification of electrolyte by adding sintering aid was found as an effective method to lowering the sintering temperature. This paper, therefore, focuses on reviewing the attempts made to modify SDC electrolyte by adding sintering aid (Li2O, CoO, CuO and FeO) in order to lowering sintering temperature. The studies related to temperature reduction, relative density, the microstructure of grains and conductivity of electrolyte was critically reviewed.

Nowadays, leachate production is a big concern and causes a serious hazard to the soil and groundwater which causes the subsurface soil to be polluted as a result of the loss of soil quality and environmental pollution. This study aims to study the potential of using kenaf core fiber and marine clay mixtures as improved landfill liner material. Relevant laboratory tests such as atterberg limit test, specific gravity test, and particle size distribution were performed to examine basic geotechnical properties of marine clay soil collected from Batu Kawan, Penang. Besides that, compaction test and hydraulic conductivity test were carried out for soil mixed with kenaf core fiber to determine the strength and permeability characteristics. The results found that the marine clay has significantly adequate physical properties to be used as a landfill liner. The permeability test for marine clay soil inclusion of kenaf core fibre indicated that the hydraulic conductivity of the samples admixture for 0%, 4%, 8%, and 12% ranged between 6.68 × 10-9 and 1.57 × 10-8 m/s. Compaction of marine clay mix kenaf core fibre samples resulted in maximum dry density, ρdmax that ranged between 0.936 and 1.595 g/cm3 and optimum moisture content, wopt that ranged between 19.8% and 24%. Hence the inclusion of kenaf core fiber in marine clay soil improves the maximum dry density value, decrease permeability of marine clay and could be potentially used for landfill liner material.

Various materials have been produced to be used as feeder material in 3D printing application to obtain the level of mechanical properties and physical properties of a product. Before to its usage as a 3D printing feed material, polyamide-reinforced carbon fibre composites were investigated for flowability and diffusion behaviour. Using a heated nozzle to transform polymer filament into a semi-liquid that is extruded to create a structure layer-by-layer, the primary issue to prevent is delamination. For the success of this study, there are 2 main methods, namely to study the physical properties of carbon fibre reinforced polyamide composites against the composition of 20 wt.% carbon fibre and to study the temperature and rheological load on the rheological properties. Rheological test analysis found that the material flowability of 20 wt.% CF/PA at temperature parameters 210 °C, 230 °C and 250 °C against rheological loads (40, 60, 80) N recorded a range of viscosity values between 48.80 Pa.s to 97.88 Pa.s and shear rate value range between 19700 s-1 to 20270 s-1. Parameter optimization analysis using Taguchi method found that the largest factor contributing to the viscosity of CF/PA composite feed material was the addition of load applied. Moreover, the microstructural results of CF/PA composites show that smoother surfaces and good polymer structural bonding occur at an extrusion temperature of 250 °C. As a result, the rheology-derived flow rate may be used to tackle the problem of delamination and layer separation in 3D printing.

The proton exchange membrane fuel cell (PEMFC) system was an electrochemical device that generates electricity through the reaction of hydrogen and oxygen without combustion. Proton Exchange Membrane (PEM) stacks typically consisted of components combined into one unit and equipped with suitable clamping torque. This was to prevent reactant gas leakage and minimize the contact resistance between the gas diffusion medium and the bipolar plate. The combined components consisted of a bipolar plate with a flow field, current collector, membrane electrode assembly (MEA), endplate, and gasket. PEMFC performance was measured concerning its power output, which depends on temperature and the operating pressure. Various efforts had been made to determine the optimal compaction pressure and its distribution through simulations and experiments. Therefore, this research analyzed the static stress of membrane electrode assembly (MEA) and gasket in PEMFC stack assembly pressure. The components’ geometric dimensions and mechanical properties, such as endplates, current collectors, bipolar plates, MEAs, and gaskets, were combined for electricity. Pressure-sensitive film (Fuji measure film prescale) was also used to visualize contact pressure distribution between the MEA and the bipolar plate. The result showed that the color variation of the pressure film indicates the exact distribution of pressure entering the stacking design and the contact image. In conclusion, the detailed contact pressure distribution was an important influence on heat transfer processes and local electrochemical reactions in cell stacks.
Design of Nonlinear Control Systems for Autorobots

Published: February 2023

Currently, various types of robots are increasingly being used to solve different tasks. Most often, these are mobile robots that move on the earth’s surface performing the assigned tasks, in particular, they are four-wheeled robots similar to a car — autorobots. As control objects, the robots are essentially nonlinear, which requires the use of nonlinear methods for the control system design. At the same time, it is difficult to apply traditional methods for designing nonlinear control systems due to a complex type of nonlinearities in the equations of mobile robots and, in particular, autorobots. In this paper, the design problem is solved using a discrete-continuous quasilinear model, which is created on the basis of the nonlinear differential equations in the Cauchy form. Due to the great complexity of the nonlinearities of the autorobot equations, the corresponding quasilinear model is created by the numerical method. The quasilinear model obtained by this method is discrete-continuous and controllable, moreover, its state variables are measurable. The discrete autorobot control system includes two practically independent control subsystems: longitudinal speed and turns. A discrete PI control law is used to control the speed, and the discrete turn control subsystem is designed by the method of desired dynamics. The resulting autorobot control system provides a stable movement along the trajectory, which can be set as a function of time or as a function of the coordinates of the moving autorobot’s position.The suggested approach can be used to design control systems for nonlinear objects of various purposes with complex differentiated nonlinearities. However, the design problem has a solution if the corresponding discrete-continuous quasilinear model of the object is controllable, and the state variables are measurable.
Intelligibility of Post-War Reconstruction in French Bombed Cities
Authors: Vialard Alice
Published: February 2023

In the aftermath of the WWII, many French cities faced a great need for reconstruction in response to the heavy destruction caused by the bombardments. Reconstruction plans were developed and implemented at relatively short notice in response to a critical and urgent situation. However, not all cities adopted the same approach: (a) some proposed and implemented a new layout; (b) others tried to recreate the old street layout but with some updates such as widening and alignment; and finally, (c) some have preferred to resort to more targeted interventions. The choice of approach was motivated by various factors associated with the level of destruction, the futuristic vision of the architect or urbanist in charge, or the historic value of the place destroyed. This article assesses the impact of these approaches on the urban tissue by measuring changes in the overall morphology and intelligibility of multiple city centres before and after the reconstruction based on their cadastral maps. Intelligibility is first measured as a configurational property of the street layout and then as a result of public participation in a navigation task using these maps and digital technology that records the speed of movement and trajectories. This allows a comparison between the original street layout and the new one, as well as across the different cities. Drawing on indicators of spatial cognition, this interdisciplinary research approach provides a means to measure and better understand the impact of the reconstruction on the intelligibility of urban environments.

Bacterial vaginosis and urinary tract infections are common conditions that lead to a decrease in the quality of life and significant economic costs. The review provides up-to-date information on the role of lactic acid in the microbiota of the vagina and urinary tract, as well as on the use of a lactic acid gel in these conditions. Bacterial vaginosis is associated with an increased risk of urinary tract infections. Antibacterial therapy demonstrates statistically significant results in treating exacerbation, but not preventing further relapses, which is due to the possible high ability of bacteria to form biofilms. Lactic acid, unlike hydrogen peroxide, is involved in maintaining the vaginal microbiota and enhancing its protective function against sexually transmitted infections, and indirectly affects the urinary microbiota. This may allow the use of lactic acid for the treatment and prevention of relapses in both bacterial vaginosis and urinary tract infections.
Evolution of views on operative delivery

Published: February 2023

This article traces the historical path of operative obstetrics up to the present time. The issues of the high frequency of cesarean section, its impact on perinatal mortality, reproductive health of the female population, mental health of the future generation (children by operation), and qualification of obstetricians and gynecologists are raised. The authors point out that there is no direct correlation between the frequency of cesarean section and perinatal mortality rates, since antenatal fetal death dominates its structure, which does not depend on the method of delivery.

Fetal growth restriction is a condition that is defined as the inability of a fetus to reach its full genetically determined growth potential. The mechanism underlying the pathogenesis is a placental dysfunction in the form of inadequate supply of oxygen and nutrients to the fetus. Clinically, this is reflected by a drop in fetal size percentiles over the course of gestation. Worldwide, fetal growth restriction is a leading cause of stillbirth, neonatal mortality and morbidity in postnatal period. Prenatal identification of fetuses with this pathology significantly reduces the incidence of adverse perinatal outcomes. However, recognizing this pathology is often a hard challenge because fetal growth cannot be assessed using only a few biometric parameters of fetal size and the fetal growth potential is hypothetical. It is also necessary to distinguish between fetal growth restriction and a fetus small for gestational age to determine the correct the management of pregnancy and the timing of delivery. In this article, we present the approaches to the management of pregnancies and deliveries in fetal growth restriction, and we identify directions for further research in this area.
