“Dairy milk is available on request”: oat milk default halves dairy milk choices in cafés. 2 natural field and 1 online experiment.
Authors: Fabris Giovanni
Published: March 2023

Diets in high-income countries need to shift from animal to plant-centric to meet climate change targets, improve human health, and reduce animal suffering. Hard regulation via bans and taxes, however, is politically difficult. Initial evidence found that setting more sustainable food options as the default option in out-of-home settings can be an effective yet liberty-preserving approach to reducing the consumption of animal products. We conducted 2 natural field experiments in the cafés of 2 universities in London over respectively 2 and 7 weeks to test whether reversing the default milk option from dairy to oat would significantly decrease dairy milk choices for milk-based barista drinks. Using data on 68,792 milk choices from 5 cafés, we estimated with a difference in difference technique that setting oat milk as the default milk option persistently decreased the percentage of dairy milk choices by respectively 23 and 55 points, with a symmetrical increase in oat milk choices. In the longer experiment, the intervention was not associated with any decrease in overall sales. In an online-based replication of the field experiments with university students (n = 212), we found that the effect was concentrated only in participants with weak relative preferences between dairy and oat milk. Additionally, we observed that over 75% of students would approve if university cafés switched their default milk option to oat milk. These results provide strong evidence that serving oat milk by default is an effective, low-cost, and viable strategy to reduce dairy milk consumption at scale.
The quadripartite approach to passion in sport: A prospective and cross-domain analysis with intercollegiate student-athletes
Authors: Schellenberg Benjamin J. I. , Verner-Filion Jeremie , Gaudreau Patrick , Chichekian Tanya
Published: March 2023

We tested if distinct combinations of harmonious passion and obsessive passion for sport were associated with outcomes within sport, academics, and in one’s life. We analyzed data from the Student-athlete Well-being and Achievement Project (SWAP), a study in which intercollegiate student-athletes (N = 298) completed assessments of harmonious and obsessive passion at the start of a season, and assessments of performance, experiences, and satisfaction in sport, academics, and in life at the end of a season. Results showed that high harmonious passion combined with low obsessive passion (i.e., pure harmonious passion) was most often associated with the most adaptive outcomes, whereas high obsessive passion combined with low harmonious passion (i.e., pure obsessive passion) was associated with the least adaptive outcomes. These results build on previous research with recreational athletes (Schellenberg et al., 2021) by showing the benefits of pursuing competitive sport with high harmonious passion, especially pure harmonious passion.
Preprint: Interpersonal emotion regulation in young adults with low and high psychosis proneness: A diary study
Authors: Riehle Marcel , Brauer Saskia , Lincoln Tania Marie , Pruessner Luise
Published: March 2023

Purpose. Emotion regulation is a complex process that often involves the presence of others, also known as interpersonal emotion regulation (IER). However, little is known about how psychotic symptoms relate to IER. We investigated whether young adults with elevated psychosis proneness engage in IER less frequently and find it less helpful than those with low psychosis proneness. Methods. Psychosis-prone young adults with attenuated negative (PP-NES, n=37) and positive symptoms (PP-POS, n=20) and a low psychosis-prone control group (CG, n=52) were recruited based on a priori defined cut-offs for the Community Assessment of Psychic Experiences. Participants provided daily diaries over one week, reporting negative symptoms, paranoia, positive and negative affect, and the frequency and efficacy of IER strategies to upregulate positive and downregulate negative emotions. Results. Multilevel models showed that PP-NES reported using IER less frequently and found it less effective compared to CG. PP-POS reported turning to others for advice in distressing situations more than the CG. These group differences were related to aberrant affect levels in PP-NES. Across groups, participants used IER less on days on which they reported more negative symptoms and used it more on days on which they reported more paranoia.Conclusions. These findings suggest symptom-specific aberrations in everyday IER in psychosis-prone young adults. Moreover, from day to day, young adults (psychosis-prone or not) appear to adjust their use of IER depending on current social motivation and distress levels. Future research should investigate whether these aberrations are dysfunctional regarding social inclusion and symptom trajectories.
Achievement Goal Perception: An Interpersonal Approach to Achievement Goals
Authors: Weissman David Laurence , Elliot Andrew
Published: March 2023

Research on achievement goals is voluminous but focused primarily on intrapersonal regulation. In the present paper, we emphasize the integral role that achievement goals also play in the broader process of interpersonal judgment. We establish a new interpersonal approach to achievement goals that integrates the extensive achievement goal literature with the well-established social relations model (SRM). We introduce and formally define the interpersonal concept of achievement goal perception, present a formal methodological approach to studying this novel concept using a Bayesian implementation of the multivariate SRM (MSRM), and put the proposed integrative approach to the test with an in-depth empirical study that directly addresses fundamental questions of achievement goal perception. In this empirical study, we measured four types of achievement goal perceptions—mastery-approach (MAP), mastery-avoidance (MAV), performance-approach (PAP), performance-avoidance (PAV)—across 1,809 student-classmate dyads from 42 small discussion-based undergraduate classes. Results indicated a predominantly perceiver-driven process consisting of self-other agreement for MAP, MAV, and PAV goals but not PAP goals, assumed similarity for each achievement goal, and greater assumed similarity among closer classmates. Achievement goal perception provided incremental predictive utility for two gold-standard educational outcomes—academic performance and intrinsic motivation—among both perceivers and targets, and four additional educationally-relevant constructs—perceived class value, perceived effort investment, perceived competence, and peer help-seeking—among perceivers. Having laid the theoretical, methodological, and empirical foundations, we discuss this new interpersonal approach to achievement goals alongside contemporary research on achievement motivation and interpersonal judgment.

Published: March 2023

Eria Hospital has implemented a fingerprint attendance system, but it has some limitations such as difficulty in reading fingerprints, limited access to fingerprint scanner which is only located in one place, and dependence on shared equipment. To overcome these problems, an Android-based attendance application was developed using Waterfall software design. This application uses QR code and GPS to make it easier for employees to record their attendance while in the work area. The quality of this application is based on ISO 25010 quality standards, which include functional testing with all functionalities working well, reliability testing with an A rating, compatibility testing with split-screen feature compatibility, security testing with an A rating, portability testing with results can be install on different devices and Android versions 8.1 to 12, maintainability testing with an A rating, efficiency testing with a startup time of around 1.6 seconds, and user experience testing with attractiveness score of 2.62, perspicuity score of 2.57, efficiency score of 2.62, dependability score of 2.51, stimulation score of 2.62, and novelty score of 2.40. Overall, the implementation of an Android-based attendance application using QR Code has proved to be a viable solution to the challenges faced by the fingerprint attendance system, and has contributed to the optimization of attendance data collection and processing in Eria Hospital.

Do we need Artificial Pollination if we have Multispecies Justice in the Anthropocene?
Authors: Price Catherine
Published: March 2023

The era we now live in is termed the Anthropocene. Climate change, land use change, pesticide and insecticide use, and pollution are all contributing to pollinator loss. To ensure food crops continue to be pollinated, artificial pollinator technologies are being developed. This article asks the question: do we need artificial pollination if we have multispecies justice in the Anthropocene? Three examples of artificial pollination technologies, Edete, Olombria, and RoboBee, are provided to help address this question. However, the companies designing and developing artificial pollination technologies do not aim to address the underlying problems of pollinator decline such as habitat loss and climate change. Addressing problems such as pollinator loss with the use of digital technology puts humanity onto the course of uncertain futures. For more just futures, there are calls for a turn towards multispecies justice. Considering pollinator loss through the lens of multispecies justice puts us on an altogether different course from that of using artificial pollination. With multispecies justice there is the potential for futures which are democratic, just, diverse, and sustainable for humans and the more-than-human world.
Repositioning Craft and Design in the Anthropocene
Authors: Tarcan Berilsu , Nilstad Pettersen Ida , Edwards Ferne
Published: March 2023

As a part of industrial mass production, the field of design has been deeply involved in the exploitation of natural resources. In design, better ways to approach the nonhuman-human relation are needed. In this article, we contribute by exploring how more-than-human perspectives can be used to engage with this relationship, and more specifically, by focusing on how the fields of design and craft relate to more-than-human worlds. Crafts are relevant as they are practices of making that preceded and exist beyond mass production. In design studies, more-than-human notions and posthumanist frameworks are still new. Although recent studies mention design in the context of more-than-human, they do not thoroughly integrate it within relationships between craft and design.
Through positioning a more-than-human approach within the craft-design relationship, the design field can learn from and shift to a more equal understanding between humans and nonhumans. The article addresses this by describing emerging craft and design practices, and by providing textile examples. Non-western textiles and their motifs are given as example artefacts that consider traditional and Indigenous knowledge in more-than-human worlds. By looking at these motifs from more-than-human perspectives, we suggest that design and craft can deliver a new approach for addressing nonhumans in human-made things.

“After All Our Efforts at Good Citizenship”: Propriety, Property, and Belonging in the Dispossession of Japanese Canadians, 1940s
Authors: Findlay Kaitlin , Wideman Trevor , Amaratunga Yasmin
Published: March 2023

This article argues that in the early twentieth-century evolution of citizenship in Canada, property persisted as a site wherein national belonging could be claimed and performed. It contextualizes a Japanese Canadian family’s performances of property and protests at their wartime dispossession within the ideals that Canadian urban reformers, planners, and property theorists set out in the 1920s and 1930s. In doing so, this article reveals the unequal access to citizenship that property ownership afforded and thus introduces a complex portrait of hierarchies of membership and belonging in Canada at this time.
Currículo Escolar do Ensino Médio: interfaces com angústia existencial e finitude humana

Published: March 2023

O artigo em pauta resulta de pesquisa teórico-bibliográfica, de natureza qualitativa, cujo objetivo é problematizar e refletir a respeito das interfaces do currículo escolar de Ensino Médio com a angústia existencial e finitude humanas. O currículo escolar carrega no seu bojo as escolhas que são feitas no que diz respeito a conhecimentos e saberes que são transmitidos no processo pedagógico, sejam eles implícitos ou explícitos. As decisões a seu respeito, na maioria das vezes, estão fora da alçada do professor, que se limita a cumprir o que lhe foi determinado. Há pouco espaço e margem para abordar questões que não estejam diretamente relacionadas ao traçado pelas políticas curriculares, como os temas de natureza emocional, existenciais ou de sofrimento psíquico dos estudantes. No ensino médio onde há muita preocupação com os conhecimentos tradicionais que levam a etapas posteriores como vestibular ou ao mercado de trabalho, a vida real tem pouco lugar no currículo, razão pela qual há necessidade de se questionar o papel da escola e sua contribuição para o ser humano concreto que necessita ser compreendido em seus dilemas antropológico-existenciais para que ela cumpra seu papel formativo

REMOTE EFFECTS OF POST-CHORNOBYL IRRADIATION ON THE BIOCHEMICAL CHARACTERISTICS OF MALE SPERMATOZOA
Authors: Klepko A. , Krupskyi V.
Published: March 2023

The present research aim was analysis of long-term radiation effects on biochemical characteristics of sperm collected from donors originating from radioactive-polluted territories of Ukraine, namely Zhytomyr oblast, Ivano-Frankivsk oblast, Kyiv oblast and Poltava oblast. Apart from this, the role of radiation component in sperm damaging was assessed.

It was found that in the most radiation polluted region - Zhytomyr the sperm samples were characterized by a large proportion of degenerative spermatozoa along with immobile sperms. Early signs of apoptosis development in spermatozoa were shown to progress gradually from Poltava to Zhytomyr. Thus, the apoptotic index for sperm samples was highest in Zhytomyr and lowest in Poltava. Also, raise in accumulated radiation dose was associated with elevation of ROS production in sperm samples.

It was shown that the ROS production for Zhytomyr donors was threefold more than for Poltava’s donors and almost twofold more than for donors from Ivano-Frankivsk. Also we found differences in the mitochondrial potential (∆ψ) of spermatozoa too. The total ∆ψ tended to drop down depending on the mean value of radiation accumulated dose, for Kyiv and Zhytomyr the mean values being significantly less than for Poltava.

Thus, our investigations have shown that subjects living on radiation polluted territories may generate a great deal of damaged spermatozoa with the hidden molecular and cellular lesions. The latter would predispose inhabitants of radiation polluted regions to male-infertility.
THE MAIN WAYS FOR METAL NANOPARTICLES DEGRADATION
Authors: Lopatko S. , Chayka V.
Published: March 2023

Progress of nanotechnology development regulates the production of substance in nanosized form, including metal nanoparticles. Therefore, they can enter agricultural land in different ways. Consequently, their further role in agrocenosis is the prerogative of modern research. So, the main issue today remains the possibility of destruction of nanotechnology products at the expense of both edaphic factors and metabolic products of plants and microorganisms to avoid their accumulation in agrophytocenoses. This article presents a review, mostly of foreign literature, to systematize knowledge of degradation pathways, mechanisms of nanoparticle penetration into the cell, their subsequent transport through tissues, and the interaction of metal nanoparticles with the environment in agrobiocenoses.

Physicochemical properties of metal nanoparticles (for example, size, charge, shape, coating) and soil properties (for example, pH, mineral composition, presence of organic acids, etc.) play an important role in elucidating the issues of decomposition, transport, mobility and interaction of nano-containing preparations with soil components .

The main role in the formation of most morphological features of metal nanoparticles, which are the basis of nano-containing preparations, played by the method of nanoparticle synthesis. Among many existing ones, in particular, transformation in plasma by evaporation, deposition of powders from solutions on a substrate, gas-phase synthesis, and others, the electrospark dispersion method was released as the most modern and progressive, since for detailed analysis we can perfectly reproduce the synthesis process of nano-containing solutions, by this method.

With the help of our own method of synthesis, by adjusting the parameters of nano-containing preparations, it is possible to predict and avoid the potential risks of using nano-containing preparations of metals in phytocenosis.

Therefore, the main goal of this review is to evaluate the potential of metal nanoparticles for degradation, to describe the prerequisites for biodegradation and to note the main possibilities of using such properties in the agro-industrial complex.
RESEARCH OF THE INFLUENCE OF THE SOIL ALGAE BIOFETERLIZE ON THE TOXICITY OF PESTICIDE RESIDUES WITH THE HELP OF BIOTESTS
Authors: Salnikova А. , Salnikov S.
Published: March 2023

The problem of pesticide residues on agricultural land does not lose its relevance, as new drugs appear that can be toxic to the natural environment. Biopreparations that have restorative properties in the soil are widely used in the world.

The use of biological preparations of microbial origin can cause a combination of various processes that can contribute to the improvement of soil properties, its remediation, etc. Especially important from the ecological point of view is the reduction of the manifestation of toxic properties of pesticide residues in the soil. Biopreparation Soil algae is a microbial biopreparation obtained by cultivating Noctoc commune bacteria using the appropriate technology. In turn, Noctoc commune bacteria have the ability to activate the processes of microbiological activity of the soil.

To study the effect of the biological preparation Soil algae, field (application of the biological preparation in various concentrations to fields with a known pesticide background) and laboratory (conducting biotesting to find out the effect of the biological preparation on the toxic properties of pesticides) studies.

Biotesting was carried out by various methods to determine the effect of the biological preparation at various stages of growth and development of agricultural crops, on the processes of microbiological transformation in the soil.

The toxicity of pesticide residues was determined in a typical medium-loamy chernozem after a field study conducted on the basis of the Agronomic Research Station of the NUBiP of Ukraine. Determination of the effect of biofertilizer Soil algae on soil toxicity was carried out using various methods, namely: determination of soil phytotoxicity on watercress, red-tip radish, peas, and durum wheat crops; determination of the inhibitory effect of biofertilizer on the growth of higher plants; study of the total number of soil microorganisms; research of the nitrifying ability of the soil according to the Kravkov method and the inhibitory effect on soil mineralization.

Phytotoxicity of typical medium-loam chernozem soil decreased with increasing drug concentration, but only up to a certain limit. The rate of the biological preparation of 8 l/ha led to an increase in the number of germinated seeds of watercress, radish, peas and durum wheat. This can be evidenced by the ability of Noctoc commune bacteria to influence processes in the soil, which contribute to reducing the toxic properties of pesticide residues in the soil.

Published: March 2023

One of the challenging issues encountered during drilling operations is the lost circulation. Numerous issues might arise because of losses, such as wasting of time and higher drilling cost. Several types of lost circulation materials have been developed and are being used to limit mud losses and avoid associated issues. Each solution has benefits and drawbacks.
In this study, a core flooding test was performed to study the effectiveness of polyacrylamide (PAM) granular gel on the reduction of the circulation lost. One common type of fracture characteristic is fractures with tips, commonly known as partially open fracture (POF). However, PAM gel therapy in POFs received little attention in prior research. Models of partly open fractures were built using a cylindrical core. A series of processes are performed on a core to get a POF model. Overall, the PAM gel can decrease plug permeability, making it a useful material for lost circulation. The results indicate that the Polyacrylamide granular gel can decrease the permeability up to 193 times.

У статті розглянуто питання оцінки впливу на довкілля видів діяльності в галузі добування корисних копалин, а саме вплив добування титанових руд на стан рослинного покриву в межах Букінської ділянки Межирічного родовища. Результати досліджень дозволяють оцінити екологічні наслідки впливу планової діяльності на біотичну складову, оцінити фоновий стан екосистем та встановити наявність чи відсутність особливо цінних територій у заповідному відношенні. Результати досліджень засвідчили те, що ділянка планової діяльності представлена в основному лісовими насадженнями. В цілому біогеоценози досліджуваної території є стійкими та придатними до існування рослинного та тваринного світу. Угрупованням боліт притаманне часткове сезонне затоплення ґрунтової поверхні. Болотні ландшафти ділянки зазнають інтенсивної сукцесії, що може призвести до зміни біотопу та біоценозів в цілому прилеглих лісів та формацій. Суходільні луки переважно розміщені в зоні впливу об’єкту планової діяльності. Частина луків заростає деревними породами сосни звичайної та берези повислої. Загалом розвиток рослинного покриву є задовільним, про що свідчить комплексний вегетаційний індекс NDVI, який зафіксований на момент вегетаційного періоду. За результатами досліджень було визначено особливості розподілу лісових угруповань залежно від рельєфу місцевості. Рідкісні види рослин та види що охороняються на території планової діяльності та в зоні впливу кар’єру добування ільменітових руд за період проведення досліджень не виявлені. В цілому лісові насадження захаращені підліском, що негативно впливає на біогеоценоз лісу в цілому, задовільні лісові формації розташовані лише на території експлуатаційних лісів.На нашу думку, для оцінки впливу діяльності на флору та фауну при будівництві та експлуатації Букінської ділянки Межирічного родовища необхідно проводити постійний моніторинг за ключовими екосистемами, що розташовані в санітарно-захисній зоні, а також у зоні впливу підприємства до 500 метрів. Пропонується удосконалити систему моніторингу досліджуваного об’єкту через проведення геоінформаційного аналізу на основі супутникових знімків та аерофотозйомки з подальшим створенням ортофотопланів.

Published: March 2023

Under the burgeoning of the digital era and global crisis of climate change and health, most countries around the world are moving to digitalize their economies. Digitalization is fundamentally changing all social and economic sectors. However, the existing studies have paid much attention on digital economy rather than digital economics. Drawing from recent literature, this paper critically reviews the understanding of digital economy by examining its meaning, main characteristics, scopes, measurement methods and identifies how digital economy differs to traditional economy. The paper, then, presents a concept and roles of digital economics and the needed suggestions for training digital economics. With this regard, the paper concludes that the education policies should be renovated in order to meet the demands on digital economy. The courses of economics should be integrated with digital economics and sharing economics.
Impact of DLC Coating Deposition on the Fatigue Strength of Al-7075-T6 Aluminum Alloy

Published: March 2023

Abstract: Al-7075 has interesting mechanical properties but is susceptible to corrosion. Physical Vapor Deposition (PVD) of coatings results in good corrosion resistance and compressive stresses of the order of 1 GPa on the surface of metallic components. However, the impact of PVD films on the strength of Al-7075-T6 is uncertain. This paper provides a summary of the findings of the Authors’ research group in recent years on the fatigue behavior of Al-7075-T6 with and without PVD Diamond-like Carbon (DLC) coating. The results indicated that DLC-coated specimens have lower fatigue strength than uncoated specimens for lives up to about 10000000 cycles. The failure mechanism was determined by observation of the fracture surfaces of the failed specimens. The stress analysis performed confirms the experimental observation, with crack nucleation expected below the surface of coated specimens, where the highest tensile stresses occur during fatigue loading.
Kindheit und Arbeit

Die Arbeit von Kindern ist weder ein Relikt vergangener Zeiten noch zurückgebliebener Gesellschaften. Mit Blick auf Lateinamerika, Afrika und Asien ebenso wie auf Europa und Deutschland schärft das Buch den Blick für die Vielfalt der Formen und Bedeutungen, die Arbeit für Kinder hat und haben kann. Der Autor hinterfragt eingeschliffene Reflexe und vermeintliche Gewissheiten und Urteile und zeigt anhand mehrerer Studien, dass bisherige Maßnahmen gegen Kinderarbeit kritisch zu hinterfragen sind.
Development and technological research of medicated lozenges for catarrhal and aphthous stomatits` symptoms relief

inflammatory diseases of the oral cavity, in particular catarrhal and aphthous stomatitis, create significant discomfort for patients in everyday life. The occurrence of stomatitis in adolescents can be associated with numerous factors: bacterial and viral infection, insufficient oral hygiene, trauma of the mucous membrane, unbalanced nutrition, allergic reactions, some types of systemic diseases etc. Medicated lozenges have advantages for use in adolescents, as they have an interesting appearance (resembling a candy), pleasant taste and aroma, do not require swallowing or washing down with water, release active pharmaceutical ingredients by gradual dissolution in the oral cavity, which ensures their local action. The present work is aimed to develop different formulations of medicated lozenges for catarrhal and aphthous stomatits` symptoms relief. The objects of the study were experimental samples of lozenges with licorice root and propolis extracts. They were chosen as active ingredients due to their antimicrobial properties, as well as their ability to improve the general condition of the periodontium and reduce the outbreak of aphthae in stomatitis. Lozenges were prepared by heating and congealing method using different concentrations of active pharmaceutical ingredients and excipients (candy base substances – sugar substitute (isomalt), glucose syrup, carboxymethyl cellulose). 3 best formulations that had a uniform color distribution and were transparent, not sticky, had no external surface defects were subjects of the development and analysis. Obtained medicated lozenges were evaluated for physical parameters like weight variation, diameter and thickness, and pharmacotechnological evaluations like friability and hardness by pharmaceutical standard methods from State Pharmacopoeia of Ukraine 2.0 (2.9.5, 2.9.7, 2.9.8). Selected samples had homogeneous physical parameters: average weight in the range of 6.98-7.00 g (none of the formulations had a deviation of more than ± 5%), diameter 3.51 cm, thickness 5.04-5.11 mm. The obtained values of hardness and friability (less than 1% for all formulations) indicate satisfactory mechanical strength of the dosage form. Stability study was carried out at (15-25) ⁰С and 60±5 % humidity rate and was determined by evaluating the appearance and pharmacotechnological parameters. The values of hardness and friability were constant throughout the storage period for all formulations. Stability studies indicated that the formulations № 1 and 2 were stable for 30 days. The present research allowed to develop formulations for obtaining a pleasant-tasting dosage form intended for relatively slow dissolution in the oral cavity – medicated lozenges for use in adolescents to alleviate the symptoms of catarrhal and aphthous stomatitis.
Substantiation of the need to implement simulation training for dental students based on the analysis of the activities of the Stomatological Medical Center at O. Bogomolets National Medical University
Authors: Chopchik Vitaliy

the article analyzes the existing problems of practical training of dental students at the clinical bases of specialized departments in the modern conditions of the health care system reforms, as well as the impact of the COVID-19 pandemic and armed aggression of the russian federation, and also substantiates the feasibility of simulation training for students of dental faculties. The research is based on the study of statistical materials of the Stomatological Medical Center in O. Bogomolets NMU (SMC), the results of an anonymous survey of graduates of the Dental Faculty, interns and doctors who underwent post-graduate training at the SMC. A tendency to a significant decrease in the number of applications for dental care to the university dental clinic has been demonstrated with an increase in the proportion of patients receiving paid dental services who were excluded from the educational process. Such tendency limits the possibility of acquiring practical skills directly during the clinical diagnostics and treatment of patients. Thus, the total number of patient visits to the SMC was: in 2012–257,115 patients, in 2019–181,507 patients, and in 2022–101,471 patients. Of these, 94,416 patients were admitted as part of the educational process in 2012, 56,693 in 2019, and 18,382 patients in 2022. A significant drop in the number of patients who visited the Stomatological Medical Center, a relatively constant number of dental students at O. Bogomolets NMU and the realities of the past three years have led to the emergence of certain restrictions and reduced opportunities for practical training of future dentists. The presented data made it possible to calculate the average number of patients per student of medical and dental education per year, which was 52.57 in 2012, 25.85 in 2019, and only 9.22 people in 2022. The limited possibility of training with the involvement of thematic patients is a reason to revise the approaches to the practical training for dentists with the expansion of the use of simulation equipment with the possibility of computer control of practicing skills. The results of the anonymous survey also confirm the need to improve the effectiveness of the practical training of dental students and interns, in particular through the introduction of new forms of training, such as simulation training. Advantages and disadvantages of this form of practical training under different conditions of organization of the educational process are discussed.
