Introduction: Since Autorefractors nowadays have become mainstream and available in almost all clinical setups Autorefractors to make measurements swiftly. So in such a situation , it is necessary to compare the results of different refraction measurement devices including Autorefractors and retinoscopy with subjective corrections in Myopia and Hypermetropia. Methods : This is a descriptive study done among 100 patients visiting Ophthalmology OPD with Myopia and Hypermetropia in Saveetha medical college selected by convenience Sampling . The data collect ed will be tabulated and analyzed using SPSS. Results: Patients were divided into two age groups to find out age wise distribution of type of refractive errors and comparing the results from the subjective examination and results given by the Autorefractive meter it is clearly from this study that the difference between two methods was almost negligible and that Autorefractors are also a reliable method of measurement in a large clinical setup. But, on the other hand, manual retinoscopy still prove to be far better and efficacious technique yielding accurate results when it is used to check for refractive errors in individuals. Conclusion: In this study, we conclude that autorefractors are also reliable and can also be used to estimate refractive errors in a clinical setup, even though manual retinoscopy remains the most accurate and efficacious method..

Published: October 2023

This study presents novel enhancements to the Backward Feature Elimination (BFE) method for improved insurance fraud detection using the K-Nearest Neighbor (KNN) algorithm. The research addresses issues inherent in the baseline BFE process, such as the over-reliance on p-values, the potential for misleading results, and suboptimal feature selection leading to overfitting. To address these, the study integrates confidence intervals and feature importance into the BFE process, establishing a more robust and reliable criterion for feature selection. Moreover, feature engineering techniques are introduced during preprocessing to enhance model performance. The modified BFE method demonstrates superior performance over the baseline model regarding the recall, precision, and F1 score. Stratified K-Fold Cross-Validation, ROC-AUC Score, and Coefficient of Variation (CV) confirm the consistency and robustness of the enhanced model across varying data subsets. These innovations offer a comprehensive and reliable solution to feature selection in the BFE method, applied to the KNN model for effective insurance fraud detection. The study mitigates the issues related to p-value dependence and boosts model performance, paving the way for more accurate and robust fraud detection systems.

Published: October 2023

Unfortunately, sequencing technology can only access the genome sequence as massive numbers of short strings are called reads. The genome assembly process constructs the complete genome from these reads based on the overlapping between the reads, called the de novo approach, or aligns the reads based on their positions in the available reference genome, called the reference-guided approach. Millions of reads search for overlapping or alignment, a well-known data structure problem called all-against-all. Many studies have proposed indexing such as hash index, prefix tree index, and parallelization technique to optimize the overlapping or the read alignment individually. However, due to the massive data amount and the repeats, limitations still affect the index efficiency, requiring more enhancements. This article introduces a new hybrid index named Prefix Tree Hash Partitioned index(PTHP), which combines prefix-tree index, hash index, pigeonhole concept, and parallelization. PTHP index reveals significant results on the simulation and real dataset, reducing the computational time complexity of overlapping and read alignment, thus the assembly time outperforming prefix tree index and hash index. Improving the performance of overlapping and read alignment using the PTHP index reveals great results in optimizing the hybrid genome assembly that combines both.
Transvaginal Ultrasound Evaluation Of Cesarean Section Niche Scar During Pregnancy: A Prospective Longitudinal Study
Authors: Abdel-Rahman Ahmed Morsy Saad , Hassanin Tamer Mahmoud zaki
Published: October 2023

Background and Objectives: To determine the prevalence of a CS scar niche during pregnancy using transvaginal ultrasound imaging, and to determine the relationship between the evolution of the CS scar niche and the ultimate pregnancy result. Materials and Methods: Transvaginal sonography was used in this prospective observational research to look at the uterine scars of 100 women at 11+0-13+6, 18+0-20+6 and 32+0-35+6 weeks of pregnancy. When the region of hypoechogenic myometrial discontinuity of the lower uterine section was discovered, a scar was discernible while pregnant. An indentation at the location of the CS scar with a depth of at least 2 mm in the sagittal axis was designated as the CS scar niche (or "defect"). Myometrial thickness next to the niche and the remaining myometrial thickness were used to quantify the hypoechogenic portion of the CS niche in two dimensions. (RMT). The entire lower uterine segment (LUS) thickness and the myometrial layer thickness were measured during the second and third trimesters of pregnancy at the thinnest portion of the scar area. In a non-selected subset of patients (n=20), CS scars were measured by two separate examiners. Scar visibility was evaluated using descriptive analysis, and the intraclass correlation coefficient (ICC) was computed to demonstrate the degree of absolute agreement between two observers for measuring scars. Maternal age, BMI, smoking status, prior vaginal deliveries, obstetric complications, and a history of uterine curettage were among the factors looked into as potential contributors to the CS scar niche. The hospital's computerized medical database provided clinical statistics on pregnancy outcomes and complications. Results: 80.9% of the ladies could see the scar. A CS scar niche was prevalent in 53.6% of people with a noticeable CS scar. Excellent intra- and interobserver agreement was observed for CS scar niche readings. There was no statistically significant correlation between maternal age, BMI, gestational diabetes, smoking status, previous vaginal delivery after CS, and niche development when subgroups of women were compared in terms of CS scar niche and non-niche. In contrast to 34.4 % of the women who did not have uterine curettage, 56.3% of the women who had done uterine curettage had uterine scar niches.  Conclusions: The CS scar niche could be reproducibly measured by a transvaginal scan in half of the cases with a visible CS scar at the first trimester of pregnancy, according to an ultrasonography evaluation. An increased chance of uterine niche formation in a subsequent pregnancy was linked to prior uterine curettage. The CS scar area may be connected to uterine scar dehiscence.
Evaluation of IUD Insertion During CS In 100 Patient. A Prospective Study
Authors: Moussa Abdelraheem Mohammed Abdelraheem , Abdel-Rahman Ahmed Morsy Saad
Published: October 2023

Background: The application of an IUD to the female after placenta delivery during a caesarean section had several benefits since the female was under anesthetic, which reduced the need for additional manipulation and pain, and the female at the time of delivery had a strong desire for family planning. IUDs placed postpartum experienced numerous disengagements, including bleeding and displacement. Objectives: To evaluate the efficacy of post placental IUD insertion during cesarean section in 100 patients.  Patient and methods: A prospective study was conducted at obstetrics and gynecology department of Damanhur Medical National Institute in the period from March 2022 to March 2023. Group I: included 52 women who agreed to insert immediate post placental IUD at the cesarean delivery. Group II: included 48 women as control group. The type of IUD used was cupper-T IUD, both groups were assessed as regard to time of cesarean section (CS), amount of postoperative bleeding, postoperative pain, occurrence of infection, any displacement of IUDs, failure of contraception and patients’ satisfaction. Results: In both groups, the demographic information was comparable. The medical histories of the investigated patients and the control group did not differ significantly according to our research. The study group's caesarean procedure took a little longer to complete. There were no appreciable differences between the two groups in terms of infection, puerperal hemorrhage, or IUD displacement. Both groups' satisfaction levels were displayed as either pain or displacement. In the research and control groups, the expulsion rates were 3.92% and 0.00%, respectively. Conclusion: Based on our research, we draw the conclusion that IUD insertion during CS is safe and effective, avoiding the reasons why it can be challenging to insert an IUD after puerperium and having a low expulsion rate; so, it can be considered a standard procedure.

This study aims to examine the complex interaction between human resource management and health, with particular emphasis on the context of the health system in Kosovo. Through detailed research and subsequent analysis, we aimed to highlight the importance of addressing specific and critical questions to senior leadership and cooperation with international organizations. The main purpose of this study is to examine the impact of human resource management on the performance and productivity of health personnel in Kosovo. We aimed to understand how factors such as motivation, working conditions and respect for employee rights affect the productivity of health personnel. To achieve the goal of this study, we used a research methodology that includes direct interviews with health personnel in health institutions in Kosovo. We used a structured questionnaire to collect data on demographics, working conditions, motivation, income and the impact of employee rights violations on their performance. The collected data were analyzed using the Statistical Technique for the Social Sciences (SPSS) to assess correlations and different effects. The analysis of the data shows a clear connection between factors such as motivation, working conditions and respect for the rights of employees with the productivity of health personnel. The results confirm a positive impact of motivation on productivity, while working conditions and lack of respect for employees' rights show a negative impact. A limited impact has been observed for the lack of respect for the rights of employees on their performance. The results of this study are of special importance for the management of human resources in the health system of Kosovo. To improve the productivity and performance of health personnel, it is necessary to address working conditions and ensure proper motivation. Interventions for improving the respect of employees' rights and increasing working conditions will positively affect the performance and quality of the health services provided.

Authors: Sergeyeva Aigul M. , Omirzakova Miroslava Zh. , Saparov Kuat T. , Nurgazina Aizharkyn S.
Published: October 2023

The trend towards the development of rural tourism is recognized to create positive dynamics for the revitalization of rural areas, and the preservation of the authentic and socio-cultural image of rural areas. Rural tourism in the regions of Kazakhstan is at the initial stage of the development. Aktobe oblast is not an exception to the general Kazakhstani trend. In the Aktobe oblast, to date, regional programs for realizing the potential of rural areas in the field of rural tourism have not been developed. An analysis of the state of the cultural environment and natural features made it possible to identify profitable resources in the local socio-economic system of the Aktobe oblast, on which rural tourism of the studied area can be built. The main directions of the resource application for the development of rural tourism are formed based on the potential resources that are available not only to the region as a whole but to each administrative-territorial unit – the district. As part of the study of the territorial system of the Aktobe oblast, regional guidelines for the development of rural tourism were identified. Rural tourism in the Aktobe oblast can be built on the resources of both natural and agricultural, historical, and cultural environments. Cultural landmarks for the development of rural tourism are represented by historical and cultural objects. We see the approach to assessing the territory of the Aktobe oblast in terms of organizing directions for the development of rural tourism in the application of the inductive method of scientific knowledge when the overall picture is formed based on the transition from a particular study of objects and phenomena to a general one. In our case, a holistic view of the development of rural tourism is obtained by analyzing natural resources, transportation, historical and cultural values of the territory and agricultural production. Insufficient and irrational use of the tourist opportunities of the territory, as well as the growing needs of the population for outdoor recreation within their region, stimulate the search. For new approaches to planning tourism activities. A new policy of rural tourism seems promising, aimed not only at the implementation of specific tourism projects but at the systemic development of tourism in the Aktobe oblast. The article develops a methodology for assessing the resource potential for the development of rural tourism and proposes the principles of zoning the territory from the standpoint of the territorial organization of rural tourism. To achieve this goal, the paper used the method of scoring, cartographic and comparative methods. Their application made it possible to ensure the validity and reliability of conclusions and proposals.

Authors: Taharchaouche Imane
Published: October 2023

The present paper aims to evaluate the accuracy of classifying Land Use /Land Cover (LULC) types and assesses the trends of their changes in the Eastern Part of Batna City (Northernf Algeria) using remote sensing and GIS. The accuracy of image Land Satellite (Land Sat ) was evaluated using the supervised classification technique, it’s applied in multi spectral and multi temporal satellite data acquired in 2000,2010,2022 and assessed with GOOGLE EARTH PRO and IMAGERY Land Use and topographical map. The second part focused on extraction of LST in three phases and explored the relationship between two land cover indices (NDVI, NDBI) and LST.LU/LC detected, quantified, and stati- cally analyzed, the result indicate that from 2000-2022 the built-up areas increased by 0.34% (6.638km2), the forest area increased by 1.8% (35.144km2), agricultural land cover increased by 1.12% (21.867km2), while bare land decreased by 2.17% (42.368km2). The conversions of areas from bare land to urban land represent the most significant Land Cover changes. The accuracy assessment and correlation coefficient R2 analysis in this study affirms the previous research findings. Even a single land use unit like built-up area, bare land and vegetation also create differences in LST (R2 of NDBI vs. LST ranges from 0.64 to 0.79; NDVI vs. LST ranges from -0.73 to -0.82). With the change of the LU/LC style, its imprint is reflected on the LST. Therefore, immediate reflection on new urbanism must be adopted, initiated and implemented to stop the warming that contributes to climate change in the study area.
The geography of public diplomacy of President of Ukraine Volodymyr Zelenskyy during the full-scale Russia-Ukraine war
Authors: Vysotskyi Oleksandr Y. , Prudnykova Olena V. , Trynyak Maya V.
Published: October 2023

Public diplomacy, as a special form of foreign policy activity aimed at shaping foreign public opinion as a factor in changing the policy of another state, requires the study of the peculiarities of geopolitical and geocultural perceptions of the foreign public. Public diplomacy has become an important channel of international communication between Ukraine and the civilized world since the beginning of the full-scale Russian offensive on its territory. The role of President of Ukraine Volodymyr Zel- enskyy in transforming public diplomacy into an effective technology of international politics is unprecedented. The uniqueness of V. Zelenskyy’s contribution to the development of public diplomacy as an international communication practice lies, first, in the incredible rise in the importance of the head of state as the main actor of such diplomacy, second, in its institutionalization and intensification as a tool for influencing global public opinion, third, in its tangible effectiveness and efficiency, and fourth, in the widespread use of digital online technologies for its implementation. The success of V.Zelenskyy’s public diplomacy is not just due to its geographically relevant content, but also to communication technologies based on geographic determinism. His public diplomacy is based on universal values, but adapted to the geocultural characteristics of the foreign public. The Ukrainian president sought to make the Ukrainian position understandable to geoculturally different audiences through a number of persuasive technologies. First of all, he used the technology of joining by appealing to values common to all geographical regions, such as life, security, freedom, children, and family. In addition, the Ukrainian national leader used the technology of engaged communication, which is empathetic, compassionate in nature and based on respect for the values, symbols, ideals, tragedies and losses that make up the geocultural background of the public’s worldview in each country. In conducting public diplomacy, the Ukrainian president outlined the geography of danger from the potential Russian threat,including the countries that were part of the USSR and the Soviet bloc. The Ukrainian national leader’s use of the technique of linking the geography of the Russian threat to the Soviet past is justified in the light of official and semi-official Russian propaganda. Exposing Russian disinformation has become one of the leading directions of V.Zelenskyy’s public diplomacy and the main information weapon against the aggressor. In proving the falsity of Russian propaganda, the Ukrainian national leader appeals to the facts, to the reasons for the distortion of the objective picture of reality and to the special geocultural experience of the foreign public, which is determined by significant historical events in a particular geographical area of the world.

La producción de alimentos con insectos ha aumentado en los últimos años a nivel mundial y se estima que continuará en crecimiento. Costa Rica cuenta con un pequeño número de productores de insectos comestibles y en los últimos años ha crecido el interés de la academia y entidades estatales por fomentar el sector. Objetivo. Presentar el mercado actual, las oportunidades, los retos y las perspectivas de la producción, procesamiento y comercialización de insectos comestibles a nivel internacional y en Costa Rica. Desarrollo. Se describe el mercado actual de los insectos comestibles a nivel mundial, los principales retos y oportunidades de su producción, procesamiento y comercialización, así como el desarrollo del sector en Costa Rica. Conclusión. A nivel mundial, los principales retos relacionados con la producción de alimentos con insectos son la baja aceptación del consumidor, la falta de tecnologías de producción de insectos y un deficiente marco regulatorio. En Costa Rica, debido a los esfuerzos conjuntos de la academia, el sector público y privado, existe un marco regulatorio base que permite la producción de tres especies de insectos para consumo humano. Los costarricenses tienen la disposición de incluir los insectos en su dieta, pero aún es necesario desarrollar mejores métodos de producción para facilitar el crecimiento del sector.

Authors: Espinosa-Cuéllar Alberto , Rivera Ramon , Varela-Noalles Mario , Pérez-Díaz Alberto
Published: October 2023

Introduction. The effective use of mycorrhizal inoculants is a challenge for Cuban agriculture. Sweet potato is an important crop for human and animal nutrition, being a mycorrhizal dependent crop with a successful breeding program. Objectives. To know if all sweet potato cultivars respond to inoculation and if its effectiveness varies with cultivars and growing seasons. Materials and methods. Two experiments were carried out during 2010 - 2012 on Eutric Cambisol soils from Villa Clara, Cuba. One at each planting time and repeated twice. The response of 17 cultivars to three inoculants application in the presence of a half dose of fertilization, and three non-inoculated treatments with fertilization levels of 0, 50, and 100 % of nitrogen, phosphorus, and potassium dose (100 % NPK) was evaluated, using a split plot design. Edible root yields, mycorrhizal colonization frequency and spores were evaluated as response variables. Results. Cultivars responded positively to inoculation and fertilization, showing differences in their yields, however, highest yields were always found when inoculated with Rhizoglomus irregulare/ INCAM-11, which were higher (p<0.05) than those obtained when receiving only 50 % NPK dose. In the rainy season with higher yields, the differentiation between inoculants was higher and in thirteen and nine of the cultivars, the yields obtained with INCAM-11 were higher (p<0.05) than those obtained with Glomus cubense/ INCAM-4 and with 100 % NPK respectively. In the low rainy season, no significant differences were found between yields obtained by inoculating INCAM-11 or INCAM-4 or applying 100 % NPK. In both seasons, inoculation with Funneliformis mosseae/ INCAM-2 was always lower. Colonization frequencies and spore production were always higher (p<0.05) when inoculating INCAM-11. Conclusion. Under these soil conditions, INCAM-11 inoculation presented better effectivity for all cultivars and planting seasons originating the highest yields and indicators of mycorrhizal performance.

Published: October 2023

Introducción. La producción de frijol está limitada por la disponibilidad de nitrógeno en el suelo y su baja eficiencia en la fijación biológica de este elemento. La aplicación de un bioestimulante a base de oligogalacturónidos (Pectimorf®) se considera una alternativa para mejorar la nutrición nitrogenada en etapas tempranas del crecimiento, pero se desconoce la efectividad de este producto en etapas posteriores del cultivo. Objetivo. Determinar el efecto de Pectimorf® en indicadores relacionados con la fijación biológica del nitrógeno y en el crecimiento de plantas de frijol común biofertilizadas con Azofert®-F, en la etapa de crecimiento R5 (prefloración). Materiales y métodos. La investigación se realizó en el Centro Nacional de Ciencias Genómicas de la Universidad Nacional Autónoma de México (octubre 2018-marzo 2019) y en el Instituto Nacional de Ciencias Agrícolas en Cuba (noviembre-diciembre 2019). Se realizaron experimentos en condiciones controladas y semicontroladas, en los que se evaluó la aplicación de 10 mg L-1 de Pectimorf® a las semillas junto con Azofert®-F y la aspersión foliar a 5 y 100 mg L-1 en plantas biofertilizadas. Como control se tomaron plantas que solo se trataron con Azofert®-F. Se evaluó la nodulación, indicadores de la fijación biológica del nitrógeno y el crecimiento de las plantas. Resultados. En condiciones controladas, el Pectimorf® estimuló la nodulación, el desarrollo radical e incrementó la actividad nitrogenasa. En los experimentos en condiciones semicontroladas favoreció la nodulación y el crecimiento, destacándose el tratamiento a las semillas y la aspersión foliar (100 mg L-1). El Pectimorf® también aumentó la síntesis de ureidos en los nódulos y el contenido de nitrógeno en las hojas. Este producto mostró más de un 15 % de efectividad con relación a la biofertilización. Conclusiones. La aplicación de Pectimorf® constituye una alternativa para mejorar la fijación biológica del nitrógeno y el crecimiento en la prefloración del frijol común.

Authors: Garcia-Rupaya Carmen R. , Chacon G. Doris M. , Caballero Garcia Carmen S.
Published: October 2023

The present study aims to identify the empathic attitude of dental students from a Peruvian public university, about their reading habits, as well as the level of studies and other sociodemographic variables. 226 first-, fourth-, and sixth-year students registered in the academic year 2022 were enrolled in the study. The Jefferson Empathy scale, which included 20 items, was used with a Likert scale ranging from 1 to 7, i.e., from totally disagree to totally agree. A file containing questions about the sociodemographic data registry was prepared together with the Jefferson Empathy questionnaire. It was found that the profile of the students was mainly feminine, and the average age was 22 years; they came from Lima. They had the habit of reading and a little more than half of the group did not participate in sports activities. The "adequate" level of empathy was the highest (51.77%). By dichotomizing the response variable, it was found that adequate empathy was related to the habit of reading, especially reading dental books. Dental students from this public university mostly have an adequate level of empathy; it is independent of the sociodemographic variables but is related to reading habits.

Authors: Vargas-Rojas Diana Carolina , Rodriguez-Flores Arturo , Moreno-Villalobos David , Chumpitaz-Cerrate Victor , Chávez-Rimache Lesly
Published: October 2023

Diabetes mellitus is a systemic condition potentially related to an increased risk of progression of various infections such as chronic osteomyelitis by accelerating the inflammatory process with bone tissue necrosis and suppuration. Therefore, if there is no proper management of these infections, they can be life-threatening as they spread to deeper spaces in the head and neck. We describe the case of a 52-year-old male patient with a history of diabetes mellitus and grade III osteoarthritis who was diagnosed with chronic suppurative osteomyelitis of the mandible. He underwent a multidisciplinary surgical intervention in which he underwent a hemimandibulectomy with immediate mandibular reconstruction. The present case highlights the importance of early and radical treatment of patients with chronic suppurative osteomyelitis of the mandible and systemic comorbidities. In addition, this case presents a review of diabetes mellitus and the risk of developing odontogenic infections and complications when invading deeper spaces in the head and neck. Therefore, in this population, careful planning is required for early surgical and pharmacological treatment.

The influence of agricultural land on the level of airborne Alternaria spores
Authors: Havrylenko Ksenia
Published: October 2023

Aim of the research was to investigate the impact of agricultural activity on the concentration of Alternaria spores.

Materials and methods. The study was carried out at the Department of Medical Biology, Parasitology and Genetics of the ZSMPhU. Samples were collected using a 7-day volumetric sampler of the Hirst type, using the volumetric method. Samples were identified under a light microscope, and spore identification and counting were limited to genus levels. The relationship between seasonal Alternaria spore levels and harvest rates was analysed using Pearson's correlation method. The effect of meteorological conditions and agricultural activity on the daily concentration of Alternaria was analysed using stepwise correlation based on logarithmically transformed daily average spore counts. Classical leave-one-out cross-validation (LOOCV) was used to estimate the mean square error (MSE), associated with this model and Bayesian information criterion (BIC) was used to assess its accuracy.

Results. Seasonal characteristics of Alternaria spores and agricultural activity in Zaporizhzhia and Dnipro regions were analysed. The connection of some seasonal and daily indicators with harvesting rates and meteorological conditions was determined. Two models with 5 and 9 parameters were found that best explain the dynamics of Alternaria spores.

Conclusions. The most significant parameters positively correlated with Alternaria spore levels were temperature, pressure, westerly wind and wheat yield; relative humidity was negatively correlated
Vitamin A accelerates the process of liver regeneration in the initial stages of Сu - induced fibrosis
Authors: Bozhkov Anatoly , Bilovetska Svitlana
Published: October 2023

Aim: To test the hypothesis about the possible role of vitamin A in normalizing the functional activity of the liver with Cu-induced fibrosis by increasing the regeneration process.

Materials and methods: Experiments were conducted on 20 sexually mature male Wistar rats, which were divided into 4 groups: a control group that was not exposed to copper sulfate and vitamin A, a group that was at the initial stage of liver fibrosis, which was provided by three consecutive administrations of copper sulfate at a dose of 1 mg/100 g of weight (one series of injections), a group that was at the stage of intensive development of fibrosis (F2), which was carried out by two consecutive series of copper sulfate injections with an interval of 3 days between injections, and a group that received vitamin A three times daily in a dose of 300 IU/100 g of weight between two series of intoxication. Body weight dynamics, relative liver weight, histological changes in liver tissues and the number of binuclear hepatocytes were determined.

Results: It has been found that animals with Cu-induced liver fibrosis did not gain or lose body weight, and the introduction of vitamin A ensured the restoration of body weight growth, and they slightly lagged behind the control group. In animals with liver fibrosis that received vitamin A, the relative weight of the liver was slightly increased and there were 2 times more binuclear hepatocytes. The structural organization of the liver tissue changed to a minor extent, and to the greatest extent there was an increase in the thickness of the Glisson’s capsule, in which immunocompetent cells were incorporated.

Conclusions: Vitamin A contributed to the normalization of liver function against the background of the development of fibrosis. The mechanism of normalization can be ensured due to an increase in the number of binuclear hepatocytes, a slight increase in the relative weight of the liver, and was accompanied by an increase in the thickness of the Glisson’s capsule, in which immunocompetent cells were incorporated
Effective means of legal regulation of foreign trade
Authors: Pyroha Serhii
Published: October 2023

The article proposes means of state-legal regulation of foreign trade, in particular legal, economic (in particular tax), political, financial and administrative instruments. The main shortcomings of the legislation are analyzed, which make it possible to effectively optimize taxation, carry out illegal export of capital and demand compensation from the budget. In order to avoid erosion of the tax base and profit shifting, a single object of taxation is proposed – value added, which is determined by the sum of factor incomes of the payers: wages fund and profit. Substantiated formation principle of the fair market value (price), which is equal to the sum of added value, VAT, charged on it, depreciation of means of production and costs, determined by the fair market value of goods/services, used in production. The established correspondence between the fair market price and the added value allows you to accurately determine the size of the tax base (VAT, personal income tax, profit tax and social contributions) and excludes any known methods of tax optimization. The amount of taxes paid determines the monetary equivalent of the added value and the increase in the sales price at each stage of production and distribution, which excludes the possibility of artificially reducing the tax base and/or transferring profits to jurisdictions with low taxes. The introduction of added value and its components as a single base of basic taxes and fees excludes weak capitalization and any other deductions from the tax base. The proposed definition of a single tax base significantly simplifies the administration of basic taxes and contributions and exhausts measures for the implementation of paragraphs 3, 4 and 5 of the BEPS plan.

The method of solution function polynomial approximation of integro-differential equations of state, which describes the transient processes of an electric circuit with thyristors, is used in this paper. The used method showed the advantages over other known methods in increasing the accuracy and reducing the simulation time of transient electrical processes by more than 6 times.

Findings. The solution is approximated by a series of Chebyshev polynomials. The integro-differential equations of state are transformed into linear algebraic equations for special depiction of the solution functions. The depiction of functions of true currents in the equivalent circuit is interpreted as direct currents. Such a schematic model creates visibility for a researcher performing simulation of transient electrical processes.

Practical value. The proposed methods discover the possibility of using the apparatus of direct current electric circuits’ theory for transient processes in complex schemes modeling with thyristors.
GeoGebra Augmented Reality to Facilitate the Manipulation of Different Semiotic Representations of Paraboloids
Authors: Lepore Mario , Mennuni Federica
Published: October 2023

In this research, we investigated whether the use of GeoGebra Augmented Reality (AR) can foster students in conceptualising a mathematical object by manipulating its different semiotic representations. We designed and implemented, with thirty university mathematics students, a teaching
sequence on paraboloids using GeoGebra AR supported by GeoGebra 3D with the aim of fostering students??? work with different semiotic representations. All the activities carried out during the teaching case study were video-recorded, transcribed, and analysed according to Duval???s Theory.
Results show how GeoGebra AR facilitated students in the manipulation of different semiotic representations of paraboloids involved by highlighting the cognitive activities of treatments and conversions which emerge while conceptualising the mathematical object at stake.
Information culture of students (on the example of a regional university)
Authors: Petryakova Elena , Goryaeva Svetlana
Published: October 2023

The article presents an overview of scientific works on the topic «information culture», identifies aspects of scientific research of the multifaceted phenomenon of «information culture». A description of the structure of the concept of information culture of students, formed as a result of the inductive method of scientific cognition undertaken by the authors, is proposed. The definition of the concept of information outlook is given, the meaning of the concepts of information literacy and information hygiene is concretized. The article presents an analysis of the practical study of the components of the information culture of students as a buffer social group that is in the stage of its active formation — both personal and professional; analysis of the results of a sociological study among students of the Astrakhan State Technical University. The study uses a quantitative method of collecting social information — a written survey. The respondents were selected using a two-stage nested sampling method. The sample size was 300 full-time students (150 boys, 150 girls) in three areas of professional training: natural science, technology and technical sciences, social sciences. As a result of the conducted research, the authors found insufficient formation of students' information culture in the components of information outlook and information literacy; a correlation was revealed between the variables «technologies and technical sciences» and «knowledge of ways to identify «fakes», students understanding of information hygiene was determined. The practical novelty of this scientific work consists in measuring the formation of the elements of the information culture of students of a regional university identified by the authors on the basis of a representative sample, taking into account the profile and specialty of vocational training in a particular university. The theoretical significance of the research is due to the introduction of the concept of «information outlook» into scientific use, the justification of the study of the essential elements of the information culture of students, the analysis of scientific papers on the topic, which allowed to expand scientific ideas about the object and subject of research.

Rama-Katha has always been a prime subject of interest and experiment in both literary forms and performative arts. It is said that it was prevalent even before the first scribe of the Ramayana, Valmiki took the initiative to document and ascribe the story a certain form. After
this the Rama-Katha was not only translated in different languages, but also underwent changes in form and shape. Rama-Katha still exist in the oral form, especially among the communities of north-east India. The objective of this paper is to explore different versions of oral
Rama-Katha of the communities, dwelling in north-east India, which are both homogeneous and heterogeneous in overtone.
Language Laboratory: A Colossal Apparatus for Catapulting English Skills: An Empirical Study
Authors: Chatterjee Santadip
Published: October 2023

To call a spade a spade, language laboratory is one of the important tools to hone the four basic skills ‘Listening’, ‘Speaking’, ‘Reading’, ‘Writing’ (LSRW) of English language. The audio-visual mechanism of a language laboratory along
with software's play a pivotal role to develop the skills of the language learners. Language laboratories are not only paramount for the pupils those who are pursuing engineering courses but also for the common learners of English language. To talk turkey to come out with triumphant in
the job market, business world, the necessity of effective and professional communication in English is at the crest. This paper enlightens the effectiveness of language laboratory, and its application by the language trainers to enhance the skills of the learners of English language for effective
communication in the professional field. This paper also zeroes in on the modern tools used in a language laboratory, kinds of language laboratories, amenities of a language laboratory, and the usages of virtual language laboratories for the language learners those who are pursuing language
courses through distance mode of education and the future of the language laboratory for developing the basic skills of English language. The methodologies of language laboratory have been emerging continuously and the new trends, tools of the modern language laboratories shall help the learners
to be proficient in terms of grammar, kinesics, vocalics, haptics, proxemics, business communication and technical writing along with the four basic skills of English language to a tee.
Enhancing the Reading Capabilities of Students with Learning Disabilities: Remedial Classroom Teaching & Learning Skills
Authors: Sahu Geeta
Published: October 2023

For a receptive human being, learning is a ceaseless process. However, learning methods at school are relatively vigorous. There can be more than one aspect which creates an impediment to the learning processes. Therefore, coping with learning difficulties can be extremely stressful
for a student. The methodology that the present paper follows is an analysis of various books on dyslexia with an intention to offer incisive insights which can be adopted by teachers in the classroom for managing the educational needs of a disabled student. After a general discussion on the
term ‘learning disabilities,’ the paper attempts to understand dyslexia, its symptoms and some techniques which can be adopted by teachers in their remedial classes in order to enhance the reading skills in students with such disabilities. In simple language, the term ‘Dyslexia’
can be understood as a difficulty in reading. A dyslexic student is commonly mistaken as a slow learner. However, the paper attempts to discuss that dyslexic students are not slow learners and by implementing certain strategies and remedial programmes, a dyslexic student can effectively excel
in academics. The paper circumspectly knits together ideas and techniques for building the reading skills of children with difficulties and provides pragmatic strategies for teachers as well as parents to help students in developing their reading skills. The conclusion of this paper offers
some tips for improving the reading skills of dyslexic students. It emphasizes on the fact that if these easy and understandable reading techniques are faithfully taught by a teacher such techniques would prove to be an aid to facilitate disabled students to strengthen their reading skills.
Also, through the bibliography of this paper, a list of resources has been created for those who may wish to seek further guidance or assistance in this area of research.
