Abstract

Education policies during the Pandemic that prioritized public safety, including students, resulted in a new problem: Learning Loss. Distance learning enforced during the Covid-19 Pandemic created a new/quite severe pain for the quality of education in Indonesia; learning from home for a long time caused students' knowledge and academic skills to decline. This problem has been widely researched by various experts in the field of education; through the literature study method, we collect references to conclude again about Learning Loss. The distance learning policy was carried out as a response from the central government to deal with the spread of the Covid-19 outbreak in Indonesia. As a result, teaching and learning activities could only run optimally if they had to make various changes to new learning methods. Educators and students need time to adapt and find effective ways to deal with these changes.

Authors: Biliaiev M.M. , Mashykhina P.B. , Tatarko L.H. , Chirkov A.O. , Chyrva M.V.
Published: March 2024

Problem statement. The efficiency of biological water purification depends significantly on the concentration of dissolved oxygen in the volume of the bioreactor. But during the operation of bioreactors, the oxygen regime changes, so it is important to predict the oxygen concentration for different modes of operation of treatment plants. Simplified mathematical models are used to calculate the oxygen regime, but these models are designed for typical bioreactors. An important task is the development of effective multivariate numerical models for evaluating the oxygen regime in reactors of different geometric shapes, which differ from “classical” reactors. The purpose of the article. Development of a CFD model for operational evaluation of the oxygen regime in bioreactors. Methodology. For mathematical modeling of the oxygen regime in the bioreactor, a two-dimensional mass transfer equation is used, which takes into account the place of oxygen supply from the aerator located in the building, the hydrodynamics of the flow in the bioreactor, and the diffusion process. The potential motion model was used to solve the hydrodynamic problem. Numerical integration of modeling equations is carried out by using finite-difference splitting schemes. At each splitting step, the difference equations are solved using explicit schemes. This allows a simple computer implementation of the numerical model. Scientific novelty. A multifactor two-dimensional CFD model was developed, which allows for a quick assessment of the oxygen regime in a bioreactor used for wastewater treatment. Practical significance. The developed CFD model and computer code can be used at the stage of designing or re-engineering bioreactors in order to find the optimal location of aerators in the structure. Conclusions. The software implementation of the developed numerical model was carried out. The results of a computational experiment on the study of the wastewater treatment process in a sedimentation tank are presented.

Authors: Dubovsky Ye.Ye. , Zaiats Ye.I.
Published: March 2024

Formulation of the problem. Automation in construction shows the potential to improve productivity after years of technical development and experimentation in the field. However, current research does not provide a clear understanding of exactly how this happens, as well as what contradictions and problems accompany construction automation. At the moment, the practice of using construction robotic equipment is not widespread in Ukraine, mainly due to the high costs of equipment compared to the wages of workers. However, as evidenced by European and American experience, the introduction of modern automated technologies into the construction process leads to increased productivity, improved accuracy and quality of work, and increased safety in construction. Despite the high cost of equipment and additional costs for training specialists and service personnel, as well as the limitations of its application, the use of construction robotics can have positive results, such as accelerating the pace of work, which will lead to large-scale changes in organizational and technological solutions and organizational and technological design in general. The purpose of the article is to analyze the use of modern automated systems and identify technical innovations and their practical potential. Conclusions. In order to gain a deeper understanding of the full potential of construction automation to increase productivity and the associated possible consequences, an objective review of information on automated technologies in construction was conducted. This review was carried out using text analysis techniques in publicly available written documents covering a wide range of relevant information sources, including scientific publications and official databases of equipment suppliers. The main vectors of worldwide research and existing technologies tested in practice are defined. The purpose, objects, tasks and goals of future research are defined.
SAFE EDUCATIONAL ENVIRONMENT: NEW CHALLENGES AND INNOVATIVE SOLUTIONS AT THE PRYDNIPROVSKA STATE ACADEMY OF CIVIL ENGINEERING AND ARCHITECTURE
Authors: Yevsieieva H.P. , Nazha P.М. , Hvadzhaia B.D.
Published: March 2024

Problem statement. Carrying out its mission in the extremely difficult circumstances of the war, the Ukrainian pedagogical community remains at the forefront of the educational front. Taking on a new, higher level of responsibility, the scientific and pedagogical team of the Prydniprovska State Academy of Civil Engineering and Architecture (PSACEA) (Dnipro city) is among the ranks of educators. The full-scale invasion of the Russian Federation on the territory of Ukraine forced us to rethink the role of education and change our view of the educational environment of our institution of higher education. In the first place, next to the traditional requirements for the educational environment, came the requirement of safety, i.e. the need to create a safe educational environment. In the martial law conditions in Ukraine, a priority goal of the state is to preserve the life and health of its citizens, especially young people, by ensuring their access to education. Access to education in war-time is the organisation of a safe educational environment. A safe educational environment is the surrounding space of an educational institution created in accordance with the institution educational goals, in which the educational process is carried out and the necessary and sufficient conditions for its participants to effectively and safely achieve the goals of education and upbringing are created. This is confirmed in the regulatory document “Concept of Educational Institutions Safety”, which aims to create equal, appropriate and safe conditions for education, to organise a safe educational environment, in particular in the of the russian federation military aggression context against Ukraine. The implementation period of this Concept is 2023−2025. The methodological framework for ensuring a safe educational environment is set out in the letter of the State Emergency Situations Service of Ukraine No. 03-1870/162-2 dated 14.06.2022. This methodological framework provides for a wide range of components for the preservation and provision of a set of objects and their attitudes to the realisation of educational goals.
IMPROVEMENT OF METHODS OF APPLICATION OF MECHANICAL METHODS OF NON-DESTRUCTIVE CONTROL
Authors: Kolokhov V.V.
Published: March 2024

Problem statement. Standardized and design parameters of concrete usually differ from the actual values obtained by the concrete of a structure during construction. The use of non-destructive testing devices usually requires their calibration, which is carried out by the vast majority only based on the results of determining the physical and mechanical characteristics of concrete of cubic samples. However, since the conditions of concrete formation and curing in the samples and the structure differ, the existing methods do not adequately reflect the properties of the concrete in the structure. Experience in the use of ultrasonic devices and personal research to improve the ultrasonic method allowed us to recommend limiting the scope of this method to periodic monitoring, since this method can easily and accurately track relative changes in the material of the structure. However, to assess the technical condition of structures, not only relative but also absolute values of the PhMC of the structure material are required. Such data, according to preliminary considerations, can be obtained with proper reliability only by using mechanical methods of non-destructive testing. The purpose of the article is determination of the way to improve the methodology for application of mechanical non-destructive testing methods. Results. The possibility of direct determination of the elastic modulus during the interaction of an indenter with a semi-infinite space with elastic-plastic properties is considered. Four stages of interaction are distinguished, depending on the nature of the forces that provide the indenter's motion, as well as the type and number of system elements involved in the interaction. The equations of conservation of the amount of motion in the system are created and the results of their solution are analyzed. Conclusions. The analysis of the conducted studies shows that it is quite difficult to obtain a solution with the necessary indicators at acceptable costs. At the same time, the reliability of the results obtained is low. To reveal the resulting uncertainty, it is necessary to introduce additional equations into the system, which can be created on the basis of additional measurements. Thus, improvement of the methodology for determining the properties of materials requires modification of the system of equations and additional measurements with subsequent calculations.

The article presents the results of deep seismic studies over the Sikhote-Alin fragment of the 8-DV reference geophysical profile running across the large fold structures of the Pacific tectonic belt, that is, the Sikhote-Alin orogenic belt with the superimposed Middle Amur sedimentary basin and the East Sikhote-Alin volcanoplutonic belt. A deep seismic section of the Earth's crust and upper mantle with the distribution of longitudinal wave velocities is constructed. In the upper part of the section, P-wave velocities vary from 4.0–5.0 km/s within the Middle Amur sedimentary basin and the eastern part of the Eastern Sikhote-Alin volcanoplutonic belt to 5.5–5.6 km/s in the central part of the Sikhote-Alin orogenic belt. It is found that the thick Paleozoic assemblage of sediments within the Middle Amur sedimentary basin is complexly faulted and folded. Crystalline rocks with compressional wave velocities of 6.0–6.2 km/s occur at depths of 8 to13 km in different parts of the Middle Amur sedimentary basin and at depths of 4 to 6 km within the Sikhote-Alin orogenic complex. Compressional wave velocities of the crust in the Sikhote-Alin fragment of the 8-DV profile are between 6.3 and 6.35 km/s. The crust varies in thickness from 32–34 km in the northern part of the fragment to 36–37 km in its central and eastern parts. Along the Moho, P-wave velocities are 8.1 to 8.3 km/s; a number of areas of reduced Vp from 7.8 to 8.0 km/s were identified in the junction zones of large crustal blocks. P-wave data were used to identify anomalies which were correlated with structural-tectonic zones, deep fault zones, and seismicity. Thus, along the deep Central Sikhote-Alin fault, the Middle Amur basin is identified, which is infilled by low-velocity sediments of considerable thickness, with Paleozoic sediments shifted to between 4 and 5 km at its junction with the Sikhote-Alin orogenic. Zones of increased heterogeneity in the upper crust projected onto the area within the contours of the Middle Amur sedimentary basin are characterized by increased seismicity.

Published: March 2024

Objective: We aimed to evaluate the effects of combined oral contraceptive active ingredients ethinylestradiol, drospirenone, and ethinylestradiol+drospirenone for histopathological changes, and endoplasmic reticulum stress levels in the liver.

Methods: In the study, 37 to 8-week-old Balb/c female mice were used. Mice were randomly divided into the control, sham, ethinylestradiol, drospirenone, and ethinylestradiol+drospirenone groups. Experimental groups were administered ethinylestradiol, drospirenone, and ethinylestradiol+drospirenone with gavage for 35 days. In liver tissue sections, histopathological changes were detected with hematoxylin&eosin, orcein, Mallory's Azan, and periodic acid-Schiff, and the presence of endoplasmic reticulum stress was detected by Chop and Grp78 immunostaining.

Results: The ethinylestradiol+drospirenone group showed significant histopathological changes compared to the control group. Some degenerative changes were noted such as swelling and size differences in hepatocytes in the ethinylestradiol+drospirenone group. When compared to the control group, an increased collagen and elastic fibers density around the vena centralis was observed in the ethinylestradiol+drospirenone group. The expression level of Grp78 protein in female mice given ethinylestradiol+drospirenone was statistically significantly increased compared to the control group. The expression level of Chop protein was significantly increased in the ethinylestradiol, drospirenone, and ethinylestradiol+drospirenone groups.

Conclusion: We concluded that the use of combined oral contraceptives increases endoplasmic reticulum stress in mouse liver tissue, and as a result, it may cause liver histopathological disorders by promoting cell death.

The significant prevalence of industrial aerosols with unintentional nanoparticles and
the increasing use of engineering nanoparticles in modern production determine the relevance
of research on the patterns of interaction with the human bronchopulmonary system.
Unintentional nanoparticles are formed during various production processes: melting and
welding of metals, combustion, crushing, grinding of minerals, plasma processing of materials.
Engineering nanoparticles are released into the air of the work area during their production
or use in any technological processes.
The respiratory system, as a barrier organ, is
most vulnerable to the effects of adverse environmental factors. At the same time,
nanoparticles are the least studied component of industrial aerosols. In order to systematize
data on the role of nanoparticles in the development of occupational bronchopulmonary
pathology, the authors conducted a literature review.
The size determines the features of
the physical, chemical and biological properties of nanoparticles. They have high values of
the ratio of surface area to volume, total surface area, which leads to an increase in
reactogenicity and penetrating power. The pathogenic properties of nanoparticles depend on the
chemical composition, shape, curvature of the surface, structure, charge, mass concentration,
total surface area of the particles, and exposure time.
The multidimensionality of
hygienic characteristics determines the complexity of hygienic rationing and monitoring of
nanoparticles. To date, safe exposure levels have not been established. When interacting with
cells of the respiratory tract, nanoparticles induce the following cellular and molecular
mechanisms: oxidative stress, inflammation, violation of the epithelial barrier, autophagy and
dysfunction of lysosomes, stress of the endoplasmic reticulum, apoptosis, senescence,
fibrosis, endothelial dysfunction, DNA damage. This leads to the development of interstitial
pneumonitis, pulmonary fibrosis and obstructive disorders, and an increase in the activity of
allergic inflammation. All these mechanisms are present in the pathogenesis of occupational
lung diseases. Under the influence of nanoparticles of various chemical compositions, separate
phenotypes of occupational chronic obstructive pulmonary disease are formed. There is a lack
of epidemiological studies of the possible etiological role of nanoparticles. Nanoparticles of
industrial aerosols are a significant factor in the development of occupational diseases of
the bronchopulmonary system and have a significant impact on the formation
of
phenotypes.

Exposure to harmful chemical factors of production can contribute to the development of
metabolic disorders in workers in the petrochemical industry. Oil production conditions are
associated with exposure to endocrine disruptors, such as aromatic hydrocarbons, whose effects
are associated, among other things, with disorders of immuno-endocrine regulation.
The
aim of the study was to analyze the features of the immune and genetic status of workers in
the oil-producing segment of the petrochemical industry with metabolic syndrome contaminated
with benzene.
142 operators of the oil production enterprise with pathology with
metabolic syndrome were examined. The observation group included workers (n=94) characterized
by contamination of the biological medium with benzene. The comparison group consisted of 48
people who were not contaminated with benzene. The state of cellular immunity was assessed by
flow cytometry (CD3+CD8+, CD3+CD95+, CD3+), cytokine profile by enzyme immunoassay (IL‑6).
Gene polymorphism was studied by real-time PCR.
In workers with metabolic syndrome
contaminated with benzene, the features of the clinical course of the metabolic syndrome,
accompanied by functional and laboratory signs of atherosclerotic vascular changes, as well as
an imbalance of the immune profile, whose phenotypes were: an increase in the absolute and
relative content of CD3+CD8+ lymphocytes (1.3–1.6 times, respectively) (p<0.05), CD3+
lymphocytes (1.2–1.3 times) (p<0.05) relative to the comparison group, CD95+ cluster
deficiency in relation to the reference interval and the indicators of the comparison group
(1.4–1.9 times; p<0.05), IL-6 hyperproduction (1.6 times; p<0.05) relative to the values
of the corresponding indicators of the group of workers where benzene contamination was
absent. The genetic profile of workers (SNP) contaminated with benzene allowed us to establish
a 1.4-fold increased prevalence of the C-allele of the FADS2 gene (OR=2.13; 95% CI: 1.05–4.29,
p<0.05); 2.3 times the G-allele (OR=3.30; 95% CI: 1.46–7.33, p<0.05) of the TP53
gene.
Established in operators of the oil-producing segment of the petrochemical industry
with metabolic syndrome contaminated with benzene, features of the immune status: an increase
in the expression of CD3+ and CD8+ lymphocyte clusters, IL-6 cytokine, and a decrease in CD95+
lymphocyte reception (p<0.05) were accompanied by polymorphisms of candidate genes FADS2
(rs174583) and TP53 (rs 1042522) associated with obesity and apoptosis.
Ethics. The study
was approved by the ethics committee of the Federal Scientific Center for Medical and
Preventive Health Risk Management Technologies. All patients were informed about the purpose
of the study, and voluntary informed consent was obtained.

Introduction. Maintaining labor efficiency, working under conditions of stress and uncertainty, high level of requirements to the functional state of workers in various professions actualize the occupational health study of work performance. Methodological applications of predictive medicine and psychogenetics make it possible to identify specific hereditary (biological) predispositions of individuals, to carry out professional orientation of a person, to provide humanistic recommendations on occupation of a certain type of professional activity. The study aims to identify a correlation between ACE genotypes and work performance capability in individuals from a professional leadership community. Materials and methods. Individuals from a professional leadership community, after dividing into two cohorts consisting of entrepreneurs and non-entrepreneurs, were interviewed and genotyped for evidence of genotype-by-insertion/deletion (I/D) polymorphism associations of the angiotensin I converting enzyme (ACE) gene and health status. Answers to 4 questions characterized the state of work performance and memory, and another 4 questions characterized the cardiovascular system. The mean age was 37±1.7 years for entrepreneurs and 34.23±0.66 years for non-entrepreneurs. There were 44 females and 129 males among them. Results. Analysis of genotyping of 173 people (25 entrepreneurs and 148 non-entrepreneurs) revealed a significant deviation of actual frequencies of I and D alleles from theoretically expected values in the whole group of managers and between non-entrepreneurs (p=0.95, χ2>3.8). In all groups, there was a marked increase in the frequency of the I/I genotype at the expense of a decrease in the frequency of the D/D genotype compared to the literature data. A significant difference between D/D and I/D genotypes in work performance was found in entrepreneurs (p=0.9817), which coincides with a significant difference between their representatives by age (p>0.99). Contrary to expectations, representatives of the D/D genotype, at least entrepreneurs, demonstrated the most optimal level of functioning of the autonomic nervous system. No associations were found between the genotype for the ACE gene (rs4646994) and work performance and memory. Conclusion. In the total sample of leaders and among the subgroup of non-entrepreneurs, a strong and reliable change in the frequencies of alleles I and D was found compared to the theoretically expected (frequencies). There was a significant increase in the frequency of I/I genotype in all groups. The significant difference in the rates between the D/D and I/D groups coincides with a significant difference between their representatives in terms of age. According to the results of test answers, representatives of entrepreneurs of D/D genotype had the most optimal level of vegetative nervous system functioning.
ScholarOne - On time online? Effects of lateness on satisfaction in virtual student meetings
Authors: Rimpler Ramon , Boos Margarete , Ritter Marie
Published: March 2024

Since the COVID-19 pandemic, student online meetings have become
increas-ingly common. This study investigates whether previously found
negative effects of meeting lateness on meeting satisfactions can be
found in the context of virtual student meetings. In an online study,
students from Germany and Italy (N = 279) rated their last meeting
experience. We investigate the prevalence of delays in student online
meetings and their relationship with participants’ process and outcome
satisfaction. About 26 % of virtual student meetings were delayed.
Satisfaction with the process and output was sig-nificantly lower in
late (vs. on-time) meetings. No differences between countries were
found.
ScholarOne - Do Protests Change Citizens' Perceptions of Political Parties? Evidence from the 15-M in Spain
Authors: Padilla Javier
Published: March 2024

Using a panel data survey in which the second wave was made just before
and after the eruption of the anti-austerity protests in Spain, and
identifying those who participated in the events thanks to a question in
subsequent waves, I leverage quasi-experimental evidence supporting that
political protests can substantially alter the perception of political
parties on the left-right dimension. I show that leftist citizens who
participated in the anti-austerity protests perceived that the
center-left incumbent party moved to the center and that this perception
remained stable over time. This situation led to an empty political
space that could have been exploited by new protest parties willing to
capitalize on this crisis of representation. Beyond showing that
political protests can quickly alter citizens’ perceptions of parties on
the left-right dimension, this article suggests that protests can create
an empty political space without the emergence of a second dimension of
party competition.
Systematic analysis of the relationship between non-alcoholic fatty liver disease and tissue iron overload: promising areas for the use of polypeptide therapy
Authors: Torshin I. Yu. , Gromova O. A. , Bogacheva T. E.
Published: March 2024

Iron overload in non-alcoholic fatty liver disease (NAFLD) is a fairly common phenomenon that receives very little attention in clinical practice. However, iron overload, leading to hemosiderosis (deposition of “indigestible” nanodispersed iron oxides in various tissues) significantly aggravates NAFLD, stimulating increased chronic inflammation, insulin resistance and hemosiderosis of other organs. As a result, ferroptosis of hepatocytes occurs (apoptosis caused by iron overload and hemosiderosis), which accelerates the transformation of non-alcoholic steatosis into non-alcoholic steatohepatitis (NASH) and, subsequently, into liver cirrhosis. Iron overload is aggravated by micronutrient deficiencies and pathogenic intestinal microbiota. The paper presents the results of a systematic analysis of this issue, describes the prospects for therapy using micronutrients and human placenta hydrolysates (HPP), which contribute not only to the regeneration of liver tissue, but also to the normalization of iron homeostasis.
