Published: July 2024

BACKGROUND AND OBJECTIVES

Geographic accessibility predicts pediatric preventive care utilization, including vaccine uptake. However, spatial inequities in the pediatric coronavirus disease 2019 (COVID-19) vaccination rollout remain underexplored. We assessed the spatial accessibility of vaccination sites and analyzed predictors of vaccine uptake.

METHODS

In this cross-sectional study of pediatric COVID-19 vaccinations from the US Vaccine Tracking System as of July 29, 2022, we described spatial accessibility by geocoding vaccination sites, measuring travel times from each Census tract population center to the nearest site, and weighting tracts by their population demographics to obtain nationally representative estimates. We used quasi-Poisson regressions to calculate incidence rate ratios, comparing vaccine uptake between counties with highest and lowest quartile Social Vulnerability Index scores: socioeconomic status (SES), household composition and disability (HCD), minority status and language (MSL), and housing type and transportation.

RESULTS

We analyzed 15 233 956 doses administered across 27 526 sites. Rural, uninsured, white, and Native American populations experienced longer travel times to the nearest site than urban, insured, Hispanic, Black, and Asian American populations. Overall Social Vulnerability Index, SES, and HCD were associated with decreased vaccine uptake among children aged 6 months to 4 years (overall: incidence rate ratio 0.70 [95% confidence interval 0.60–0.81]; SES: 0.66 [0.58–0.75]; HCD: 0.38 [0.33–0.44]) and 5 years to 11 years (overall: 0.85 [0.77–0.95]; SES: 0.71 [0.65–0.78]; HCD: 0.67 [0.61–0.74]), whereas social vulnerability by MSL was associated with increased uptake (6 months–4 years: 5.16 [3.59–7.42]; 5 years–11 years: 1.73 [1.44–2.08]).

CONCLUSIONS

Pediatric COVID-19 vaccine uptake and accessibility differed by race, rurality, and social vulnerability. National supply data, spatial accessibility measurement, and place-based vulnerability indices can be applied throughout public health resource allocation, surveillance, and research.

Представлено результати дослідження пелюсток волошки синьої (Centaurea cyanus L.) спектрофотометричним методом. Встановлено, що для фармакогностичного аналізу лікарської сировини може бути використана сукупність спектральних характеристик надмолекулярного пігментного комплексу протоціаніну у пелюстках: наявність довгохвильової смуги із розподіленими максимумами у спектрах відбиття та кольоровий стимул із домінувальною довжиною хвилі у діапазоні синього кольору. Виявлені діагностичні ознаки відрізняють тип із синім забарвленням як основний об’єкт під час заготівлі сировини офіцинальної лікарської рослини від інших різнозабарвлених типів за умов внутрішньовидового поліхроїзму квіток. Нативний протоціанін отримано в результаті водної екстракції пелюсток із синім забарвленням. Прояв максимумів у спектрі поглинання водного синього екстракту відповідав характеристикам протоціаніну in vivo у спектрах відбиття пелюсток типу із синім забарвленням. Відмінність спектральних властивостей хромофорних систем цих форм встановлена за параметрами диференційного спектру поглинання розчину неасоційованого антоціану після кислотної руйнації нативного пігментного комплексу відносно екстракту протоціаніну. За умов спиртової екстракції пелюсток у кислому середовищі відбувалось руйнування пігментних комплексів, які локалізовані в поверхневих тканинах, і утворення похідних флавілія. На відміну від спектрів відбиття різнозабарвних пелюсток із розподіленою смугою, особливістю спектрів поглинання їх екстрактів є наявність одного максимуму, положення якого залежало від типу забарвлення та свідчило про домінування глікозидів пеларгонідину або ціанідину. Отримані результати удосконалюють фармакогностичні критерії та можуть бути використані під час створення біопрепаратів і функціональних харчових продуктів на основі сировини волошки синьої.

Purpose: This study was planned to investigate the effect of gender on pain, upper extremity functions and quality of life in patients with type I and type II diabetes.
Methods: A total of 130 patients with type-I and type-II diabetes were included in this study, which was a web-based cross-sectional study. In the study, arm, shoulder and hand problems questionnaire, Michigan hand outcome questionnaire, numerical rating scale for upper extremity pain severity, neuropathic pain questionnaire-Short Form, and World Health Organization quality of life questionnaires were used.
Results: While women's scores on the pain subscale of the Michigan hand outcome questionnaire were higher than men (p = 0.006), the scores on the function subscale were lower (p = 0.037). When the working subscale scores of the disabilities of the arm, shoulder and hand questionnaire were examined, it was determined that the function level of women was lower (p = 0.016).
Conclusion: Diabetes has a different impact on men and women in terms of pain, upper extremity function, and overall health. Women appear to be more affected than men in terms of pain and upper extremity function.

Published: July 2024

The aim of this study is to selectively remove As(V) ions, the most common type of arsenic in drinking water and especially surface water. For this purpose, a super macroporous polymeric cryogel column was prepared using the molecular imprinting technique. MAC was chosen as the functional monomer due to the high affinity of arsenic to sulfhydryl (-SH) functional groups. MAC monomer was synthesized from the amino acid cysteine. Physicochemical properties of HEMA-based synthesized poly(HEMA-MAC) cryogel were determined by SEM FTIR surface area and swelling. Adsorption studies from water were carried out in a continuous system. Different parameters such as pH, flow rate, temperature, ionic strength and time were studied to determine the optimum conditions for the removal of As(V) ion from water. The maximum As(V) removal of poly(HEMA-MAC) cryogel was 189.4µg/g polymer at pH: 5.0 and 15ppm concentration. In selectivity studies conducted in the presence of PO43-, SO42- and NO3- ions. According to the relative k values obtained from the selectivity experiments, As IIP cryogel shows 1.52 times more selectivity for As(V) ion than PO43- ion, 2.61 times more selectivity for SO42- ion and 1.53 times more selectivity for NO3- ion than NIP cryogel. From the theoretical calculations, it was found that the As (V) adsorption was fit with the Langmuir isotherm and the adsorption process obeyed pseudo-second order kinetics.

Published: July 2024

During the COVID-19 pandemic, higher education institutions needed to adopt a different learning format from in-person classes. One of the alternatives was the so-called Emergency Remote Learning (ERL), transforming traditional in-person teaching into synchronous remote instruction. This study aims to gain insights into online learning best practices based on a Brazilian university survey in which students periodically responded to an open-ended question about their experience with ERL over a determined period. Data was collected at different times during the first year of the pandemic and encompassed more than 19,000 responses. Students' responses to the open-ended question were analyzed using the Academic Communities of Engagement (ACE) framework. Analyzing student perceptions of the ERL period allowed for reflection on relevant aspects of students' emotional, cognitive, and behavioral engagement, with potential applications in synchronous or asynchronous online teaching contexts. Students associated remote learning with online modalities, expressing exhaustion and difficulties managing studies, work, and family. Negative comments regarding technology, methodology, and instructors affected cognitive, emotional, and behavioral dimensions. The data underscores that online synchronous activities necessitate accessible technology, specific strategies, and methods that foster collaboration to build engagement. This article gives insights for implementing remote teaching experiences aimed at student learning and satisfaction.

Published: July 2024

To obtain a comprehensive understanding of the primary breakup mechanism of dual-layer, rotating conical liquid sheets, the spray field of a dual-orifice, pressure-swirl atomizer is observed using high-speed shadowgraphy. The influences of the pressure drop in the primary and pilot flow channels and of the merger of the dual-layer liquid sheet on spray morphology, spray cone angle, and liquid sheet surface fluctuations are investigated on the basis of an analysis of spray field images. Attention is
focused on the mechanisms underlying the behavior of the disturbance waves generated during the merger of the dual-layer liquid sheet. The results of this study reveal that the pressure drops in the primary and pilot flow channels affect the spray pattern, spray cone angle, and liquid sheet surface fluctuations. It is found that the influence of the pressure drop in the primary channel is dominant,
and the changes in the liquid sheet surface fluctuations are related to the spray pattern. During liquid sheet merger (after the inner sheet has reached the expected spray cone angle), the spray cone angle of the outer sheet decreases, and only after the sheets are in contact with each other does the amplitude of the surface fluctuations become significantly larger and generate more medium- and high-frequency disturbance waves.

The purpose of the study: was to compare the concentrations of bacterial infection indicators lactoferrin (LF) and lactoferricin (LFC) in the blood serum and peritoneal exudate of patients with destructive forms of acute appendicitis after laparoscopic and laparotomic appendectomy. The concentrations of LF protein and LFC peptide were studied in blood and peritoneal exudate samples of 45 patients with destructive forms of acute appendicitis of varying severity after laparoscopic or laparotomic appendectomy. When studying the levels of LF and LFC in patients with acute destructive appendicitis, it was found that their levels differ from the donors' figures by 3 times for both LF and LFC. It was found that the concentrations of LF and LFC in patients with acute destructive appendicitis and appendicular peritonitis are 3 times higher than the donors' figures for both LF and LFC. As for the peritoneal exudate of patients with destructive forms of acute appendicitis, they were compared with the results of the same patients in the blood serum. In this case, a statistically significant excess of peritoneal concentrations over serum levels in patients with acute destructive appendicitis and appendicular peritonitis is characteristic only for LF (by 3–4 times), but not for LFC. Comparison of the levels of the two studied biochemical indicators in the blood serum and peritoneal exudate in patients with destructive forms of acute appendicitis after laparoscopic and laparotomic appendectomy options did not reveal a reliable relationship between LF and LFC and the type of appendectomy. Thus, tests for LF and LFC in patients with destructive forms of acute appendicitis are primarily closely related to the severity of patients with acute destructive appendicitis and appendicular peritonitis. The antibacterial properties of LF and LFC have been actively studied in recent years in emergency medicine for abdominal surgical infection. The fact is that a serious problem in antibacterial therapy of abdominal infection is the rapid development of resistance to known antibiotics, which requires the use of increasingly new classes of antibiotics and antiseptics and the development of new classes of antibacterial agents, including lactoferrin and its derivative lactoferricin. We have found that, despite the common nature of these substances, the mechanisms of action of the LF protein and LFC peptide on bacteria differ significantly, which is confirmed in our study using the example of studying both tests in destructive forms of acute appendicitis. LF in surgical abdominal infection primarily reflects various bactericidal and bacteriostatic effects of iron in the blood, intestines and abdominal cavity. The short peptide LFC is not associated with iron metabolism, which does not prevent this peptide, due to its unique amino acid composition, from exhibiting in the experiment even higher antimicrobial activity than LF.

Among all benign formations, lipomas are the most common and are located on any part of the body. However, they are rare in the oropharynx and oral cavity and account for 1-4% of cases. The tongue is devoid of fat cells, but there have been cases of patients with formations on the walls of the tongue, which, after morphological verification, were recognized as lipomas. The priority direction of treatment of these formations is surgical. The presented clinical cases confirm the importance of timely diagnosis of formations and the need for their removal.

Hypoxia is a condition that occurs when there is a decrease in the normal level of oxygen due to a decrease in the availability or delivery of this gas to cells and tissues. It is important to note that hypoxic conditions occur in many diseases. With a low oxygen content in tissues and cells, numerous physiological and pathological changes occur. The article summarizes information from the scientific literature on the effect of hypoxia on the immune system. The analysis shows that the lack of oxygen has a significant effect on the regulation of the immune response. This influence is mediated by a family of factors induced by hypoxia. Among them, the most studied is HIF-1α. The action of factors is carried out by various mechanisms. The influence of factors induced by hypoxia was registered in the analysis of the function of all cells of natural and acquired immunity.

To compare blood creatinine levels in children with constitutionally exogenous obesity and in children without obesity. Materials and methods of research. The analysis of serum creatinine levels (Jaffe colorimetric method) was carried out in 162 children with constitutionally exogenous obesity, including overweight children, grade 1–4 obesity and 178 children of the control group who were treated in the Department of endocrinology of the Regional Children's Clinical Hospital of Astrakhan in the age range from one and a half to 17 years. The study period was more than 10 years. The criterion for exclusion from the study was the absence of concomitant pathology of the urinary system. The results and their discussion. When comparing serum creatinine levels in two groups of children (obese and non-obese), a significant increase was found in the group of children with constitutionally exogenous obesity. Thus, creatinine in the blood ≥ 120.0 mmol/l was recorded in 25 children out of 162 examined with constitutionally exogenous obesity and in 3 children out of 178 without obesity (χ 2 = 19.43; p < 0.00001). The highest serum creatinine levels were recorded in children with obesity of 1–2 degrees. Conclusion. Constitutionally exogenous obesity is associated with chronic impairment of nitrogen excretion function of the kidneys.
Dynamics of changes in clinical blood parameters in patients in the early postoperative period with gastroesophageal cancer during nutritional support
Authors: Gaziev M. A. , Kutukov V. V. , Yakimenko Ya. A.
Published: July 2024

Perioperative nutritional support is one of the important components of complex surgical treatment of the esophagus and stomach. According to various authors, protein-energy deficiency in cancer patients in 20–80 % of cases with cancer reduces body weight – an independent predictor of permanent continuation of the disease. Surgery, as one of the treatment methods, which is the strongest stressor, causes catabolic reactions, significantly increasing the loss of protein and energy in patients. However, at present, the need to prescribe artificial nutrition in the perioperative period is questioned and there is no consensus on artificial nutrition in the perioperative period. Numerous comparative studies and recommendations for its implementation are very diverse. Given the widespread use of nutritional mixtures, a thorough study of the effect of nutritional support on the dynamics of hematological and biochemical parameters in this pathology is required.

Published: July 2024

La muerte, para los humanos, no es un proceso natural sino un hecho cultural, fundado en y fundador de diversos comportamientos sociales, generalmente materializados en ritos funerarios. En este artículo se presentan algunos elementos teóricos desde la antropología y la sociología para explicar los conceptos de rito, símbolo y representación, lo cual se articula con un rastreo del concepto de desmentida en Freud, para arribar a la propuesta de un concepto de desmentida de la muerte. Se toma el tema de la muerte desde la perspectiva antropológica, explicando las diferentes concepciones y representaciones en torno del tratamiento cadáver, elemento principal en los ritos funerarios. Finalmente, se recogen todos estos elementos para explicar cómo los ritos funerarios se convierten en formas de desmentida de la muerte.

El propósito de este artículo es analizar la dinámica relacional de las familias que decidieron no tener descendencia. Este es un estudio exploratorio de tipo cualitativo, analítico, de corte transversal. Se realiza entrevista en profundidad a 7 familias que por decisión propia y no por circunstancias biológicas han optado por no tener descendencia. El análisis por categorías mostró que la relación con las familias de origen gesta cambios en los modelos de relación, posibilitando una nueva mitología familiar, es decir, una narrativa alterna. Priman los intereses individuales por encima de los construidos en pareja. La no descendencia puede ser un medio para que uno o los dos miembros de la pareja, consigan la nutrición relacional deficitaria en el otro, razón para reconocerlos como sistema familiar.

IMPLEMENTING CLINICAL LEARNING IN HEALTH CARE STUDIES IN HIGHER EDUCATION INSTITUTIONS OF LATVIA: THE STUDENT PERSPECTIVE
Authors: Briza Ilze , Pipere Anita
Published: July 2024

The purpose of this study was to disclose the opinions of the students on the implementation of clinical learning in health care studies in Latvian higher education institutions (HEIs). The study focusses on the awareness, evaluation, and recommendations of students for the effective adoption of clinical learning in their curricula. The volunteer sample (N=41) was composed of students from two HEIs (82% women) mostly from aesthetic cosmetology and medical massage programmes. A mixed-type structured questionnaire was used to collect the data. To analyse the data, the integration of thematic analysis of qualitative data with the frequency analysis of the data elicited by quantitative questions was applied. The students admitted that clinical learning is implemented in their curricula and explained it as the training in knowledge and practical skills in the workplace. The development of theoretical knowledge, practical skills, and communication with experienced tutors was recognised as the greatest benefit, while the lack of time for this study form was observed as the major hindrance to clinical learning. It was also recommended to prepare clinical tutors for pedagogical work, improve the availability of teaching materials, and increase the opportunities to deal with clinical practice situations. Students also stressed the need for feedback from clinical teaching lecturers, experience of different clinical situations, and support of the team during clinical learning. The results of the given exploration coincide with the results of similar studies conducted in other countries, indicating that experience in the clinical environment and practical work during clinical learning ensure the best study results for future healthcare professionals. The results of this pilot study will pave the way for a larger study on the topic and will have an impact on the implementation of clinical learning in health care curricula in Latvia.
TEACHER’S PEDAGOGICAL SELF-EFFICACY FOR ENSURING THE QUALITY OF EDUCATION
Authors: Liepa Dace , Ročāne Maija
Published: July 2024

Nowadays we are living with conscious awareness of change around us. Therefore, openness to change and problem-solving skills become essential transversal competences for everyone. However, teachers often perceive changes in their work environment as problems rather than challenge and opportunity to improve the quality of education. Thus, persistence and creativity in solving problems becomes an important indicator of a teacher’s self-efficacy. To promote the quality of education, teachers’ pedagogical self-efficacy becomes important, which significantly affects the learning achievements of students. Pedagogical self-efficacy consists of the teacher’s confidence in abilities regarding lesson planning, student assessment, choice of teaching strategies, etc. One of the basic principles of educational progress is inclusive education and acceptance of diversity. Creating a positive school psycho-emotional environment and creative pedagogical strategies also become important. The literature review is used as a research method to summarize the theoretical foundation of the topic. Theories provide a comprehensive explanation of a particular aspect of nature of the phenomenon of self-efficacy supported by evidence. The aim of the publication is to analyse the aspects of teacher’s pedagogical self-efficacy focusing on the way it affects the quality of education, which also includes the promotion of students’ internal motivation and preventing behavioural problems.
PROVING OPTIMIZATION BY COMPARISON OF BUSINESS PROCESSES
Authors: Pavlov Plamen , Gladchenko Victor
Published: July 2024

One of the biggest problems in the practice of any business process analyst is how to prove the process optimization they have performed to the management and/or the management of the company/organization, who are neither specialists in business process analysis (at least in most cases) nor specialists in higher mathematics (even more rarely).
The problem is further complicated by:
- the fact that the introduction of changes in a business process can also change the related business processes (the so-called "process chain reactions"), which could lead to a change in the functioning of the entire business process system of the firm/company under consideration (and in the whole spectrum from "extremely positive development" to "total degradation" and even bankruptcy/closure) if not taken into account;
- the right-proportional "objectivity-complexity" ratio of the methods that could be used for the purpose (i.e. the more objective and accurate a method is, the more complex it is);
- overly complex (especially from a mathematical point of view) methods look unconvincing in the eyes of the management/management of the company/organisation;
- overly simple (especially from a mathematical point of view) methods look unconvincing in the eyes of the more mathematically and/or more analytically oriented leadership/management of the company/organization;
It is therefore necessary to find a method (or more than one) that meets the following conditions:
- allows the objective evaluation of business processes;
- allows the comparison of business processes before ("as-is") and after ("to-be") optimization;
- allows the consideration of business process changes that are related to the optimized business process - i.e. evaluates and analyzes process chain reactions;
- compares similar business processes - for example, the stocking processes of two different firms/companies.et.

The world's urban population is projected to grow to 68% by 2050. According to statistics, 68% of the country's population already lives in Latvia in 2022. Much of the air pollution research in the city is focused on researching highways and streets of very intensive traffic. Small and medium-sized cities with their infrastructure remain unexplored. The population of cities of different sizes is growing every year, so it is important to understand the prevalence of pollution along the streets in small and medium-sized cities, as this pollution has a direct impact on the health of the city population. Snow and stored dust are good matrices to assess the extent of air pollution and metals in urban areas. It should also be stressed that the number of cars in cities is increasing, while the age of the car fleet remains increasing. The aim of the study is to find out how iron is distributed at different distances from the street section in Jelgava city research facilities. Snow samples were collected at 3 monitoring points with a distance of 1 m, 50 m, and 100 m to each side of the street. Snow samples were melted, acidified, filtered, and measured with ICP-OES spectrometer. For data analysis, descriptive statistics, the Kruskal-Wallis test, and the Steel-Dwass-Critchlow-Fligner procedure were used. In all monitoring points, iron pollution in air at 1 m is statistically significantly higher than at 50 m and 100 m (p-value 0.018; and 0.011), which directly indicates the impact of cars on air quality close to the streets. At the monitoring point located on Riga Street, the iron concentration at 1 m distance is 10.9 mg/l and at 100 m 0.33 mg/l. The data obtained can be used when designing streets and conducting urban planning.

Aronia melanocarpa is a hardy berry-producing shrub that demands low maintenance and can grow on almost any type of soil. Since the best fruits can be obtained on the branches younger than 7 years, pruning of 1/3 of the shrub is usually performed each winter or after flowering, and also to remove damaged or overgrown branches. For sustainable production of Aronia melanocarpa berries, it is necessary to find a rational use for this pruning lignocellulosic biomass. Some studies available for Aronia melanocarpa berries show that they are very rich in various biologically active substances with proven functional and pharmacological activities including anti-inflammatory, antioxidant, and antimicrobial properties. The chemical composition of Aronia melanocarpa branches is currently almost unknown. The study aimed to evaluate the composition and potential of chokeberry branches as a source of polyphenols. General chemical characterization of the biomass was carried out using the method of analytical pyrolysis. Extraction of branch biomass was carried out using aqueous alcohol solutions. Quantitative analysis of the extracts showed a large amount of oligomeric proanthocyanidins. The most suitable extractant was determined to obtain the highest yield of the dominant polyphenols in the hydrophilic extract. The antioxidant activity of the hydrophilic extracts as well as antibacterial activity against six pathogenic bacteria was evaluated. The results showed the high potential of chokeberry lignocellulosic biomass as a source of valuable biologically active compounds for the creation of preparations for the healthcare, nutrition industry, and cosmetics.

The article is devoted to the study of the economic efficiency of GHG emissions from the use of energy in agriculture in the EU and the candidate country for accession - Ukraine. Using the abstract-logical method, the essence of the category "economic efficiency of greenhouse gas emissions" was clarified and an indicator for its assessment was proposed. By actual statistical data and the method of economic analysis, calculations of the economic efficiency of carbon dioxide emissions from the use of energy in agriculture of the EU member states and Ukraine were made. The key factor influencing the economic efficiency of GHG emissions from energy consumption in the agricultural sector was identified. Due to econometric method of approximation estimation and the Excel software package, the presence of a direct, high-density linear relationship between energy consumption and carbon dioxide emissions in agricultural production was established. By ranking method and comparative economic analysis, a threshold value of energy consumption per hectare of agricultural land was found, which corresponds to a relatively high value gross production per ton of carbon dioxide emissions among the studied countries. It was established that for the candidate country for joining the EU - Ukraine and for the two Baltic countries - Latvia and Estonia, in order to increase the level of economic efficiency of GHG emissions in terms of implementation the European Green Deal, it is worth paying primary attention to the growth of economic productivity. Also, due to graphical and tabular methods of processing statistical data, it was established that the use of environmentally friendly energy (in particular, electric energy) in the process of agricultural production is not a key factor affecting the economic efficiency of GHG emissions.

Published: July 2024

This pilot study assesses the reliability and validity of measurement tools and instrumentation to ensure accurate measurement of the variables and defines possible problems of the follow-up larger-scale research. The study’s overall goal is to measure stakeholders' perspectives on the use of generative artificial intelligence (AI) in higher education and its implications for university social responsibility (USR) with the purpose of better understanding how AI technologies are deployed in academic institutions. The primary aim of this pilot study is to evaluate the effectiveness of the designed questionnaire by calculating Cronbach's alpha coefficient of the measurement scales. A questionnaire of 20 items was disseminated to the relevant stakeholders, including students, and academic and administrative staff, with the total number of received valid responses being 101. Cronbach's alpha was used as a measure of internal consistency to test the reliability of the measurement scale that consists of two groups of items: Scale B) perceptions of AI use in higher education of all the relevant stakeholders; Scale C) AI integration into higher education and its implications for USR. Key findings and implications from the study results include good or acceptable internal consistency > 0.7 among the majority of the items in the questionnaire. Specific recommendations for improving some of the items were suggested based on the findings. Modifying language, rephrasing questions, or deleting items that lead to reduced internal consistency are examples of these. The pilot study provides useful insights on the viability of employing the questionnaire in a larger-scale study, and considerations for time and resource allocation to ensure practicality in the subsequent study.

Published: July 2024

Higher education and digital transformation are two essential areas that interact and influence each other today. The rapid development of technology requires higher education institutions to provide students with the digital skills needed in the labor market and everyday life. At the same time, educational institutions are embracing digital solutions to improve the efficiency of the learning process and offer new opportunities for students and lecturers. The digital transformation of higher education covers many areas, including integrating multimedia systems in the study process. This process refers to the use of digital technologies to enhance the learning experience by making it more interactive, accessible and effective. The integration of multimedia systems can include several aspects, including interactive classes, seminars and lectures on various collaborative platforms, interactive learning materials (e.g., interactive e-books, videos with 3D animations or simulations, virtual or augmented reality solutions), e-assignments and tests, automated assessment systems (data analysis and learning analytics). Also, multimedia systems can help universities to automate study administrative processes. The aim of the study is to analyse the solutions for integrating multimedia systems in higher education, their potential for digital transformation of study courses and for increasing the efficiency of the study process. The study used both qualitative and quantitative methods for data extraction and analysis. The study uses a case study approach - it evaluates the digitisation initiative of 12 distance and face-to-face bachelor level study courses of Turiba University, integrating multimedia system solutions for asynchronous learning process into the course content and form. The case study analysis includes a student evaluation survey of the study courses through an online questionnaire, semi-structured interviews with course developers and lecturers, as well as document analysis. As a result of the research, the authors conclude that the integration of multimedia systems in studying study courses provides additional support to students in strengthening their self-directed learning skills. At the same time, under the influence of the digitalization of the study process, the space for both asynchronous and direct communication between lecturers and students, for the development of soft skills of students, as well as for the formation of practical knowledge and competences, increases the efficiency of the study process and the quality of education.
