Results of Implementing Preventive Health Measures for Workers of Certain Occupations in the Shipbuilding Industry
Authors: Mal’kova NYu , Petrova MD
Published: June 2022

Background: The shipbuilding industry is one of the leading sectors of the national economy of our country. In St. Petersburg, shipyards employ up to 60 % of all blue-collar workers, most of them being engineering technicians and shipbuilding specialists. Chippers occupy a special place among the latter. It is known that chippers performing heavy and extremely heavy physical labor often develop occupational diseases induced by hand and arm overstrain, such as epicondylosis, rotator cuff syndrome, and osteoarthritis. Prolonged static and dynamic loads on the upper extremities in combination with hand-arm vibration and forced postures cause dystrophic changes in the cartilage (arthrosis), and then in the bone tissue (osteoarthritis), thus necessitating appropriate preventive measures to preserve work ability of shipbuilders, including chippers.
Objective: To evaluate effectiveness of specially developed and patented techniques based exposure to low-intensity laser radiation for restoring occupationally impaired functions of the musculoskeletal system.
Material and methods: In 2021, we studied working conditions of 38 chippers and 25 engineering technicians aged 35 to 58 years, with at least 10 years of employment, experiencing muscle tension and overstrain of the upper extremities. All the workers were examined by a surgeon and a neurologist. To restore the functional state of the upper limb blood supply, laser radiation in the red region of the spectrum was applied to the back surface of workers’ hands. Regional blood circulation of the hands was then evaluated using a Mizar-REO rheograph, Mizar LLC, St. Petersburg, Russian Federation.
Results: After ten 5-minute sessions of radiation therapy, the number of complaints of general fatigue, irritability, lethargy, weakness, and sleep disturbance decreased by 2.5 and 3 times in chippers and engineering technicians, respectively. The number of complaints of headaches, pain in the heart and hands reduced as well. Only two chippers reported persistence of some minor pains in their hands. The regional blood circulation also demonstrated an objective improvement.
Conclusion: Exposure of the dorsal side of hands to low-intensity laser radiation in the red region of the spectrum effectively relieves vasospasm of the upper extremities and leads to an improvement in blood supply. Introduction of the developed preventive care measure will contribute to occupational disease and disability prevention.

Published: June 2022

Applicability of artificial neural network (ANN) modelling in predicting the water quality index (WQI) and in turn to ascertain the suitability of the water for human consumption has been presented in the paper. In the light of the present study, seventy-nine (79) groundwater samples were collected from two mandals (divisions) Veeraghattam (VGT) and Palakonda (PLKD) and analyzed for physicochemical parameters during the pre-monsoon and post-monsoon seasons of 2015 and 2016. In computing the WQI, physicochemical parameters such as pH, EC, TDS, TH, Ca, Mg, chlorine, fluoride, nitrite, DO and TA have been considered. From the results it was found that the WQI varies from 43.9 to 46.5 and 31.4 to 34.7 in VGT and PLKD divisions respectively. ANN tool in MATLAB has been used to predict the WQI. Back propagation methodology and LM algorithm has been chosen for the study. To train the network, physicochemical parameters have been given as inputs and the already computed WQI values as output. A particular season has been chosen for testing the network. After simulating the network, the results obtained were compared with the experimental value and found to have an error of 0.6%. It is inferred that the chosen model fits apt for the prediction of WQI in the present study.
Towards Co-existence. Responsibility in the Anthropocene Debate
Authors: Szyndler Jeremiasz
Published: June 2022

P. Crutzen and E. Stoermer’s concept that humanity has entered a new geological epoch – the Anthropocene, in which the human species has become the leading geological force, is the subject of multidisciplinary scientific research. The debate on the Age of Man reconnects the sphere of facts and the normative sphere, while still continuing the eco-developmental concept oriented towards the search for new socio-economic solutions. One of the assumptions of the naturalistic narrative of the Anthropocene is the conviction that human action has the greatest impact on the environment and we are responsible for its condition. Often compared in literature to other great revolutions in science – Copernicus‘ and Darwin‘s theory – the paradigm shift in thinking in the Anthropocene  forces us to rethink the key concepts of classical philosophy: human, nature, responsibility. The article presents an outline of the ethical debate on responsibility in the Anthropocene, considering its collective and individual aspects, and introduces a new concept of co-existence, which integrates ecosystems with the technosphere.
Impact of Entrepreneurship on Sustainable Development in Emerging Markets under the Conditions of COVID-19
Authors: Ivanović-Đukić Maja , Rađenović Tamara , Veselinović Nemanja
Published: June 2022

This paper investigates the contribution of entrepreneurship to sustainable development and economic growth in emerging markets in the period before and during the COVID-19 pandemic. Additionally, the importance of various measures implemented by entrepreneurs and governments as responses to the changing environment in the COVID-19 pandemic is examined. By employing the data for 20 emerging markets, the findings revealed that only high-growth-expectation entrepreneurship (HEA) had a significant contribution to economic growth before the pandemic, but this relationship became negative during the COVID-19 crisis. Furthermore, this research pointed out that sufficient responses to the COVID-19 pandemic could be a useful instrument to encourage the development of entrepreneurship and revive the economy in the post-COVID period in emerging markets.

Published: June 2022

Abstrcat

In this study, electrospun microfibers (MFs) were produced and used as key materials to optimize the composite with liquid crystal (LC) for terahertz (THz) wave phase shifters. These MFs, with an average diameter of 1.4 μm, were produced using the polymer solution concentration of 14 wt% and spinning voltage of 13 kV. When MFs were combined with LC, the measured results of the electrical characteristics showed that 14 wt% MFs provided an outstanding solution to the problem of a significant reduction in the natural birefringence of pure LC. The birefringence in the THz frequency range of the composite using 14 wt% MFs approached 90% compared with that using pure LC. Additionally, the decay time drastically shortened from hundreds of seconds for pure LC to hundreds of milliseconds for MF/LC composite and was independent of device thickness.
Dissociation mechanism of a C60-Li+ complex by microscopic hydration: density functional theory study
Authors: Kawabata Hiroshi , Tachikawa Hiroto
Published: June 2022

The hydration structure and electronic state of Li+ doped complexes on the surface of C60 were investigated by density functional theory calculations. This system is a simple model for the solvation of Li+ at the anode of a lithium-ion battery. C60 and Li+ bind at approximately 35 kcal mol−1. The new band of C60 formed the lowest excited state, 0.1 eV smaller after interaction with Li+. The water molecule preferentially interacted with the Li portion of the C60-Li+ complex, and a micro-hydration structure was formed around Li+. When four or more water molecules were added to the system, Li+ was removed from the C60 surface by the water molecules, and a hydration shell was formed around both Li+ and C60 (separate hydration). The electronic interaction between C60 and Li+ was completely disrupted by the formation of a microscopic-hydrated shell. Herein, the mechanism is discussed based on the theoretical results.

New Bounds on the Size of Permutation Codes With Minimum Kendall T-distance of Three
Authors: Abdollahi Alireza
Published: June 2022

We study  $P(n,3)$, the size of the largest subset of the set of all permutations $S_n$ with minimum Kendall $\tau$-distance $3$. Using a combination of group theory and integer programming, we reduced the upper bound of $P(p,3)$ from $(p-1)!-1$ to $(p-1)!-\lceil\frac{p} 3}\rceil+2\leq (p-1)!-2$ for all primes  $p\geq 11$.  In special cases where $n$ is equal to $6,7,11,13,14,15$ and $17$ we reduced the upper bound of $P(n,3)$ by $3,3,9,11,1,1$ and $4$, respectively.
Metaheuristics for allocation and sizing of PV-STATCOM
Authors: Machado Alves Zedequias , Mota Martins Renata , Marchesan Gustavo , Junior Ghendy Cardoso
Published: June 2022

Distributed Generation (DG), especially photovoltaic distributed generation (PVDG), has contributed significantly to serving the growing demand for active power. However, the necessity to meet the demand for reactive power is still challenging. In addition to active power generation, photovoltaic inverters can be used to provide ancillary services to the grid, including reactive power compensation. This paper proposes a metaheuristic approach based on Particle Swarm Optimization (PSO) for allocation and sizing of photovoltaic inverters performing the complementary function of static synchronous compensator (PV-STATCOM) units. The objective function of the above-mentioned approach is to minimize the initial investment in the acquisition of PV-STATCOM units. The proposed methodology takes into account both daily load curve and generation and is applied to the 33 Bus Test System. The results show improved grid voltage profile throughout the day. Also, the photovoltaic inverter did not fail to perform its main function, i.e., that of generating active power. One of the major contributions of the proposed methodology is that it will assist investors in determining the allocation and sizing of PV-STATCOM units to perform the ancillary service of reactive power compensation in the grid.

Authors: Iannuzzi Giulia
Published: June 2022

Joan-Pau Rubiés is specialised in the study of cross-cultural encounters in the early modern world, from a perspective combining the contextual analysis of travel accounts and other ethnographic sources with the intellectual history of early modern Europe. Recent work has focused on the analysis of early modern ethnography and its intellectual impact in the period 1500-1800. This has involved developing various lines of research, including the history of travel, cross-cultural diplomacy, religious missions, early orientalism, race and racism, and the history of cosmopolitanism. In recent years, he has been working on the development a global comparative perspective on these various topics (encompassing both Asia and the New World) that might help interrogate critically the Eurocentric categories of the Renaissance and the Enlightenment.
Amassing Global History
Authors: De Luna Kathryn M.
Published: June 2022

This essay takes as its framework the competing definitions of ‘global’ as a concept through which we can reconsider the scope of global history. More specifically, it advocates for the adoption of truly global archives, such as the historical information embedded in language, by the field. Such a methodological move will generate historical scholarship that better situates the impact of oral societies in global history on their own terms.

Gift Exchanging Practices between the Kingdom of the Two Sicilies and the Ottoman Empire: ‘Cose Turche’ and Strange Animals
Authors: D'Amora Rosita
Published: June 2022

Between  August 1741 and the spring of 1743, following the conclusion of a treaty between the Kingdom of the Two Sicilies and the Porte, Naples became the stage of a series of attentively choreographed events starring two special guests:  Hacı Hüseyin Efendi, an envoy of the sultan Mahmud I and an elephant, presented as a sultan's gift to the King Charles of Bourbon. Both guests became a public spectacle, aroused great curiosity, and generated many written and visual responses. Resorting to both the Neapolitan court-sponsored  textual and visual reconstructions and to unpublished archival documents, this article shows how the both on- and off-stage performances arranged to present the envoy, and the sultan's gifts,  had the clear intent of leaving a long-lasting impression on the new Ottoman ally, but also  aimed to assert the power of the Bourbon king inspiring sentiments of wonder, admiration and devotion in his subjects.

Published: June 2022

Aims: Adhesive small bowel obstruction is a common surgical problem, yet there has been no standard protocol for its management. In the absence of bowel strangulation, majority of adhesive obstruction cases can be treated conservatively. The purpose of this study was to evaluate the possible use of liquid paraffin in the management of adhesive small bowel obstruction conservatively in the pediatric age group, and its safety and effectiveness in reducing the hospital stay and operative intervention rate. Methods: This prospective randomized study was conducted in 30 patients who had diagnosed post operative adhesive small bowel obstruction, attending the department of Pediatric Surgery, SMS Medical College and Attached hospitals Jaipur, during the period between October, 2014 to March, 2016. After stabilization, patients were received liquid paraffin through nasogastric tubing in addition to the conservative treatment. Serial clinical and radiological monitoring was performed. If symptoms of peritonitis developed or if the obstruction did not resolve spontaneously after seventy two hours of admission, a laparotomy was performed. The duration of hospital stay, time between admission and first oral feed, passage of stool/flatus was recorded. Results: The mean duration of hospital stay was 5.2 days. 7 (24%) patients not improving after seventy two hours of conservative therapy underwent exploratory laparotomy. Patients who responded to conservative therapy, the time to oral feed was 3 days. No serious adverse reaction was noted after liquid paraffin administration. . Conclusion: The use of liquid paraffin in adhesive small bowel obstruction is safe and reduces the need for surgical intervention.

Background: Knee arthroscopy is a common orthopedic procedure done worldwide. Despite its minimally invasive nature compared to the traditional knee surgery, post-arthroscopic pain may be severe, and the patients generally require a significant amount of opioid-based analgesics after such procedures. Aim: The objective of present study was to compare the block of femoral nerve at adductor canal using ropivacaine with additives like Fentanyl with regard to longevity and density of the block in comparison to plain ropivacaine. Methods: Patients of either sex in the age group of 18-75 years, having body mass index (BMI) of 20-35 kg/m2 and belonging to ASA (I & II), who were scheduled to undergo elective knee arthroscopic surgeries were observed in this study. On the evening before surgery, the visual analogue scale (VAS) Scoring was explained to all patients. All the included patients were categorized into two groups viz. GROUP A: Received 20ml of 0.2% Ropivacaine + 2ml of Normal Saline (Total 22ml), GROUP B: Receiving 20ml of 0.2% Ropivacaine + Fentanyl 1mcg/kg diluted in 2ml of Normal Saline (Total 22ml). Results: Sedation score was assessed by using Ramsay Sedation Score (RSS). There was no significant difference in demographic profile of the patients among various groups. Difference in the duration of analgesia was statistically significant among the two groups with longest duration in Group B (7.6+1.20 hours) and was least in Group A (4.3+1.70 hours) (p value <0.01). Total consumption of analgesia (Injection Tramadol 1mg/kg, IV) over a period of 24 hours in Group A was 200+28.76mg and in it Group B it was 108.9+30.64mg. Total quantity of rescue analgesia consumed was more in Group A as compared to Group B among the two study groups (P value <0.001).Incidences of side effects in the subjects were insignificant and only few side effects were noted like, 3.4% of patients in Group A had nausea. 3.2% patients in Group B had vomiting. Bradycardia was noted in 3.4% ...

Published: June 2022

Respiratory distress syndrome, resulting from a deficiency of surfactant, is the most frequent clinical respiratory disorder in preterm infants. It is the most critical cause of morbidity and mortality in preterm infants. The present study INSURE was done in a total of 100 Preterm neonates who came with respiratory distress syndrome with <35 wks and <1.5kg to NICU, Department of Pediatrics, King George Hospital, Andhra Medical College, Visakhapatnam from January 2018 to July 2019 to know the usefulness of INSURE in a resource-poor setting where the only surfactant is given with NCPAP, where a poorer patient can afford and can decrease the morbidity and mortality of MV. This study concludes that, among spontaneously breathing, premature infants treated with INSURE, decreased the need for subsequent MV by 22%. The higher birth weight, the use of antenatal steroids, the lower RDS score at the time of the procedure, and the early use of surfactant as the good predictors in the INSURE success group. There is a significant decrease in the need for MV in the surfactant group compared to the control group. The reduction in the need for MV decreased the risk of air leak syndrome and is advantageous in medical settings where resources are limited, like in our country.
Association of Visceral Fat with Pulmonary Function in Hypothyroidism Patients
Authors: Singh Dr. Harminder
Published: June 2022

Introduction: Hypothyroidism is divided in primary, caused by failure of thyroid function and secondary (central) due to the failure of adequate thyroid-stimulating hormone (TSH) secretion from the pituitary gland or thyrotrophin-releasing hormone (TRH) from the hypothalamus. Secondary hypothyroidism can be differentiated in pituitary and hypothalamic by the use of TRH test. In some cases, failure of hormone action in peripheral tissues can be recognized. Primary hypothyroidism may be clinical, where free T4 (FT4) is decreased and TSH is increased or subclinical where FT4 is normal and TSH is increased. In secondary hypothyroidism FT4 is decreased and TSH is normal or decreased. Primary hypothyroidism is most commonly caused by chronic autoimmune thyroiditis, less common causes being radioiodine treatment and thyroidectomy. Material and Methods: This is a case control study conducted in the Department of General Medicine, NC Medical College & Hospital, Israna, Panipat over a period of 1 year. A total of 120 patients with age between 18 to 60 years were included in the study. The study included 2 groups, group 1 consisted of 60 newly detected hypothyroids and group 2 with 60 controls who were age, sex matched and from similar environment as that of cases. Group 1 hypothyroid patients include both clinical (TSH >5 milli units/L with clinical features of hypothyroidism or low Free thyroxine (FT4)) and subclinical hypothyroidism (TSH>5 with no clinical features of hypothyroidism or normal FT4). Results: In this study, there is no significant difference in age and BMI in cases and controls. TSH was significantly higher while FT3 and FT4 were significantly lower in cases compared to controls. FVC between cases and controls did not show statistical significance, although the mean FVC was found to be lower in cases (1.73) as compared to controls (2.23). Furthermore, observed that there was no significant correlation between TSH or FT4 with FVC, FEV1, and FEV1/FVC as seen in
Anemia in Indian Children and Management
Authors: Solomon P. John , Chellaraj Margaret , Margaret A. Priya
Published: June 2022

Anemia is defined as hemoglobin level of less than the 5th percentile for age [1]. It is a common condition in children seen in everyday practice. It has to be detected early to prevent complications. Anemia is more common in children below 2 years of age. Most children with mild anemia are asymptomatic. Hence, in many countries where the prevalence of anemia is very high it is common practice to screen for anemia at 1 year of age. Most cases of anemia in our country are caused by nutritional deficiency of iron, and or vitamins. Simple investigations and treatment are adequate to diagnose and manage most of the cases of anemia. Medical practitioners should have a thorough knowledge about the common causes of anemia and their management. Referral to a Pediatric Hematologist is required only in some cases. Before arriving at a conclusion we should compare the blood results with normal values for that age. Anemia in the newborn may be due to blood loss, hemolysis caused by blood group incompatibilities or abnormalities of the cell membranes of the RBCs or its enzymes. During infancy and childhood the commonest cause of Anemia is nutritional, of which iron deficiency is more common. Folic acid and B12 deficiency can also cause anemia. Thalassemia major and severe forms of hereditary spherocytosis cause anemia and jaundice requiring blood transfusion and iron chelation and folic acid therapy. Autoimmune hemolytic anemia is not common in children. In some inherited diseases like Thalassemia Hematopoietic Stem Cell Transplantation offers the best hope for cure.

Published: June 2022

Hereditary spastic paraplegia (HSP) is a rare neurodegenerative disorder presenting as lower limb spasticity having two clinical types and various modes of inheritance. A young male patient presented with bilateral lower limb weakness of one-year duration showing both sensory and motor abnormalities on examination. MRI of brain and spine done as part of workup revealed marked atrophy of anterior corpus callosum with abnormal signal intensity at tips of frontal horns of ventricles mimicking the appearance of the ear of a Eurasian lynx. No other abnormality was encountered in the brain or spinal cord in our case. Other imaging abnormalities which can be encountered in such a case include periventricular and central white matter changes as well as spinal cord atrophy. Pathologically this condition is recognised by degeneration of lateral and posterior columns of the spinal cord. The differential diagnosis includes structural, metabolic, neurodegenerative, motor and nutritional deficiency disorders.

Synovialosarcomas are rare, malignant mesenchymal tumors common in adolescents and young adults. They preferentially affect the lower limbs. Much more rarely, at the level of the chest wall. Contrary to its name, synovialosarcoma does not develop from synovial tissue. We report the case of a 17-year-old adolescent girl, followed for monophasic synovialosarcoma of the chest wall, the diagnosis of which was confirmed by immunohistochemistry. Treatment consisted of neoadjuvant poly chemotherapy followed by concomitant radio chemotherapy and closing surgery. This observation confirms the value of multimodal management in the treatment of this type of pathology.

Published: June 2022

Aorto-mesenteric Clamp syndrome is a rare disorder. The diagnosis is clinical and then radiological. Treatment is first medical and then surgical in case of failure. The aim of this work is to focus on this pathology. An 18-year-old patient, who for a month and a half presented with early postprandial vomiting, associated with diffuse abdominal pain and constipation, all of this resulted in an inability to perform and a deterioration of the general condition of the patient along with an estimated weight loss of 10 kg. The clinical examination gave confusing results, the patient was hemodynamically and respiratory stable, but also cachectic, dehydrated, along with a distended, with the presence of epigastric bruising. The biological assessment showed u renal failure associated with fluid and electrolyte disturbances. ASP did not show any hydroaeric levels. Abdominal CT without and with PDC injection was in favor of aorto-mesenteric clamp syndrome (AMCS). Medical treatment was mainly symptomatic. Five days after its admission, the patient's neurological and respiratory status worsened and the patient required assisted ventilation. The patient passed away on Day 2 post-intubation.
Black Women & Women's Suffrage: Understanding the Perception of the Nineteenth Amendment Through the Pages of the Chicago Defender
Authors: Alexanian Tamar
Published: June 2022

Susan B. Anthony once famously stated, “I will cut off this right arm of mine before I will ever work for or demand the ballot for the Negro and not the woman.” The racism of many early suffragettes has been well documented and discussed; Black suffragettes and other suffragettes of color were, at best, relegated to the margins of the movement and, at worst, scorned and turned away by white suffragettes. Moreover, part of white suffragettes’ strategy for passage of the Nineteenth Amendment was based on racist appeals to white men; white suffragettes claimed that passage of the Nineteenth Amendment would help keep white voters in the majority and, ultimately, would help uphold white supremacy. Against this backdrop, Black women—and much of the Black community more generally—still supported and fought for the passage of the Nineteenth Amendment.

Recent legal and historical scholars have been dedicated to studying the often-overlooked and instrumental role that Black women played in the Suffrage Movement and Black enfranchisement. This Article seeks to look at the coverage by Black—largely male—journalists at the Chicago Defender in the ten years preceding and proceeding the passage of the Nineteenth Amendment. In doing so, this Article hopes to better understand the ways that some Black community members understood and viewed the Nineteenth Amendment and how that perception changed. Although in hindsight we understand that the Nineteenth Amendment was not the liberating feat for Black women that it was for white women, what does Black journalistic coverage in the period immediately before and after its passage tell us about the perception of the Nineteenth Amendment and Black women’s enfranchisement at the time?

The methodology of this research differs from those used in other historical research regarding Black women’s suffrage. Many historians have focused on understanding Black women’s suffrage through studying individual women’s stories: In her groundbreaking and well-received book Vanguard: How Black Women Broke Barriers, Won the Vote, and Insisted on Equality for All, legal historian Martha Jones says that “by recounting the lives of some of the many Black women who engaged in political fights, the picture of a whole comes into view.” These histories rely on a large variety of historical documents left behind by, and about, individual suffragists and events to gain an understanding of “the picture of a whole.” This Article takes a different approach: it looks deeply at only one set of primary documents—articles printed in the Chicago Defender— to better understand the changes and patterns in community perception revealed through journalistic coverage. This is not counter to the important work of these other historians, who have helped recover the overlooked stories of suffragists of color. Instead, this Article seeks to further our understanding of these stories through a different medium.
Defining Sexual Orientation: A Proposal for a New Definition
Authors: Park Andrew
Published: June 2022

Laws prohibiting discrimination based on sexual orientation are becoming more common in all parts of the world. Few of these laws provide useful definitions of the term sexual orientation. As a result, the meaning and impact of these laws remains unclear. This Article reviews past and current definitions of sexual orientation according to how well they incorporate current empirical knowledge of sexual orientation, and how their use in human rights laws impacts the dignity, right to equality, and human development of sexual minorities. The Article gives particular attention to the definition of sexual orientation found in the Yogyakarta Principles which has been adopted by a number of jurisdictions throughout the world. Because this definition views sexual orientation through a heteronormative lens, its use restricts sexual freedoms and undermines the dignity of individuals with non-confirming sexual orientations. The Article proposes a multidimensional definition of sexual orientation grounded in current scientific knowledge of how sexual orientation is manifested in the lives of sexual minorities.

Pregnant transgender people’s experiences vary: they may identify as male or non-binary and may seek gender-affirming medical care to different degrees. This variety in gender identities and bodies puts additional pressure on CJEU’s pregnancy discrimination case law—a case law that is, as this Article argues, already flawed. Building on a critique of the CJEU’s decision in Dekker, this Article discusses three alternative approaches to addressing pregnancy discrimination in EU law. The first two approaches are different ways of construing pregnancy discrimination as sex discrimination. First, the Article discusses a gender-stereotyping approach to direct sex discrimination, and, second, an indirect sex discrimination analysis. The third approach is to introduce a separate provision on pregnancy discrimination in EU legislation. This Article argues that this third approach provides the fullest protection for all types of pregnancy discrimination—including the pregnancy discrimination that pregnant transgender people experience.

У статті здійснено кількісний аналіз онлайн-курсів для підготовки до зовнішнього незалежного оцінювання, розташованих на україномовних платформах масових відкритих онлайн-курсів. З’ясовано, що зовнішнє незалежне оцінювання є обов’язковим етапом для вступу до закладів вищої освіти. Одним із засобів підготовки до нього є використання масових відкритих онлайн-курсів, перевагами яких є масовість, доступність, якісний освітній контент, часткова безкоштовність. З’ясовано, що найбільш актуальними україномовними платформами є Prometheus, EdEra, EDUGET, ВУМ. Усього на розглянутих онлайн-платформах розташовано 21 онлайн-курс для підготовки до зовнішнього незалежного оцінювання. Найбільше таких курсів (10) розташовано на онлайн-платформі EDUGET. Більшість онлайн-курсів призначено для підготовки до зовнішнього незалежного оцінювання з математики (8 курсів) та англійської мови (5 курсів). Аналіз їхніх назв на різних платформах свідчить, що вони частково не відповідають назвам навчальних предметів, які складаються під час зовнішнього незалежного оцінювання. Висвітлено етапи проходження онлайн-курсів на україномовних онлайн-платформах. Визначено перспективи подальших досліджень, що передбачають детальний аналіз структури та змісту онлайн-курсів з української мови та літератури.
