Published: April 2023

Problem statement. One of the approaches to solving the problem of predicting the academic performance of students is displayed. Unlike existing studies in this area, which are mainly aimed at predicting the effectiveness of graduation, that is, based on the results of intermediate certifications that allow us to assess the chances of students to successfully graduate from a university, the results of this study are aimed at predicting the success of education in the early stages of the educational process. Methodology. A feature and novelty of the proposed prognostic model is the forecasting of student performance based on the Markov model, the data sources of which are universal predictors of an e-learning course that determine the success of subject education based on the personal characteristics of the student. Results. The authors present a description of a predictive model for assessing the success of subject education in the context of digitalization of education, reveal their experience of its approbation for students of the Siberian Federal University in the field of study “Informatics and Computer Engineering” and the results of a qualitative assessment of the model. Conclusion. The prospects for building a digital service for predicting the academic performance of students in the electronic information and educational environment of the university based on the results of the study are stated.

Authors: ÖZKAN Bülent , GÖKÇE Harun
Published: April 2023

Guidance munition has become one of the popular subjects in both the theoretical and applicable studies since they could find a wide field of use in recent years because of their high performance and lower collateral damage capabilities as per the improving defence concept. The use of smaller and lighter guided munition makes the stated advantages increase without relinquishing the effectiveness. In this study, the design of a guidance kit which makes the mortar projectiles become guided when released from aerial platforms and the relevant computer simulations performed upon a selected projectile model are investigated. Here, two different configurations are considered based on the rotational degree of freedom of a pair of fins mounted on a rotary ring. In the simulations in which it is assumed that the guided projectile is released from an unmanned aerial vehicle, the different values of the fin deflection, autopilot switching duration, and side wind are considered for both of the mentioned geometries. Finally, the final miss distance and time of flight values obtained for all the designated cases are compared.

Regional Discrepancies in the Level of Knowledge-Based Economy in Poland
Authors: Bąk Iwona Dorota
Published: April 2023

Subject and purpose of work

This paper analyzes the level of knowledge-based economy (KBE) in terms of sustainable development across the provinces (voivodships) of Poland in 2020. The underlying assumption of this study is that knowledge and skills are one of the fundamental preconditions for successfully implementing the concept of sustainable development.

Materials and methods

In order to calculate the rankings of Polish voivodships a synthetic indicator developed on the basis of the zeroed unitarization method was used.

Results

There are vast disproportions in the levels of KBE across the voivodeships of Poland. The most advanced KBE was identified in the Mazowieckie Voivodship, and the least developed KBE was found in the Lubuskie voivodship.

Conclusions

The capacity to develop a knowledge-based economy is inextricably interrelated with the quality of the social capital, which is directly attributable to the levels of education. In order to offset the interregional disproportions spending on research and development needs to be increased and the investments in human capital (e.g. through career planning, training, improving the professional qualifications of employees, discretionary bonuses) and new technologies should be expanded.
Comparative Analysis of Methods for Hourly Electricity Demand Forecasting in the Absence of Data – A Case Study
Authors: Zawadzki Jan
Published: April 2023

Scope and purpose of work

This paper examines the impact of the number of gaps in data, the analytical form, and the model type selection criterion on the accuracy of interpolation and extrapolation forecasts for hourly data.

Materials and methods

Forecasts were developed on the basis of predictors that are based on: classical time series forecasting models and regression time series forecasting models, hybrid time series forecasting models and hybrid regression forecasting models for uncleared series, and exponential smoothing models for cleared series of two or three types of seasonal fluctuations, with minimum estimates of errors in interpolation or extrapolation forecasts.

Results

Adaptive and hybrid regression models have proved to have the most favorable predictive properties. Most hybrid time series models for systematic and non-systematic gaps and for both analytical forms are single models that generally describe fluctuations within a 24-hour cycle.

Conclusions

The lowest estimators of prediction errors involving interpolation were obtained for exponential smoothing models, followed by hybrid regression models. A reverse sequence was obtained for extrapolative forecasting.
Digital Sovereignty and Identity in the European Union: A Challenge for Building Europe
Authors: Ivic Sanja , Troitiño David Ramiro
Published: April 2023

Summary

This paper aims at showing how the concepts of national sovereignty and national identity are challenged by the digital revolution. In the age of modernism, both concepts were defined as a condition for society’s loyalty to the political framework, but this long-established format changed with the new technologic developments. The digital revolution requires a postmodern – heterogeneous and fluid – idea of identity, as well as a post-modern idea of sovereignty, which is non-territorial, neither hierarchical. Therefore, the postmodern idea of sovereignty and the concept of identity are significant for the development of the concepts of digital sovereignty and European digital identity.
The Populist Discourse of the Hungarian Prime Minister: The Case Study of Gyöngyöspata and Migration Crisis
Authors: Ismayilzada Tofig
Published: April 2023

The study aims to analyse if the Hungarian prime minister attempted to portray an ‘other’ image of the Roma ethnic minority group during the segregated primary school conflict in Gyöngyöspata. Moreover, the study will explore the Hungarian prime minister’s discourse on the migration crisis to understand if Viktor Orbán adopted the same communication strategy as in the Gyöngyöspata conflict. Comparing the two cases will allow us to identify the key similarities and differences in the discourse adopted by the Hungarian prime minister in different events. This research uses the qualitative content analysis methodology to examine the collected data. Besides this, the study concludes that Viktor Orbán attempted to portray an ‘other’ image of the Roma ethnic minority group during the Gyöngyöspata conflict. This study aims to fill a gap in the literature by analysing the Hungarian prime minister’s discourse on the Gyöngyöspata conflict and comparing his discourse on both cases.
Cui prodest? Why local governance came to a deadlock in Hungary
Authors: Kákai László , Kovács Ilona Pálné
Published: April 2023

More than thirty years after Hungary’s transition to democracy and the change of territorial governance model, the time is now right to assess the outcome. This paper is primarily an assessment, concluding that the deadlock of the Hungarian local government system can be explained not only by the centralisation efforts of the governing and opposition political elites or the continuous decline of the budgetary position, but also by the indifference of local society. The fact is that the Hungarian local governments were not protected from being squeezed out of a significant part of public services, from a narrowing of their room to manoeuvre and from their authority position being weakened, by the general constitutional provisions introduced in 1990. An important proposition of this paper is that (local) society, although still more trusting of local governments than the central government according to various surveys, has not been able to become an ‘ally’ of local governments. The question rightly posed in the title of the paper is, whose interest is the local government system, who finds the values of self ‑governance important? The paper seeks (based mainly on academic literature and on its own and secondary analyses) the reasons/changes that have led to the stalemate of Hungarian local governments despite their initially strong mandate.
What Explains Party Membership in Post-Yugoslav Countries: Socialism, Nationalism, Clientelism or False Reporting?
Authors: Čakar Dario Nikić , Čular Goran
Published: April 2023

Earlier studies on party membership in Central and Eastern Europe (CEE) led to the conclusion that political parties in new democracies are not inclined to build strong party organisations or invest in recruiting members. However, several recent individual country studies point to the opposite conclusions, indicating that there are significant cross ‑country variations in party membership figures across the post ‑communist region. By using a unique dataset on party membership in post ‑communist Europe, in this article we argue that the average membership level in CEE seems to be higher than in Western Europe. This holds true even when party membership figures for CEE countries are ‘corrected’ after conducting validity and reliability tests. Furthermore, we also find that party membership figures across CEE countries vary to a much higher degree than in established Western democracies. Our analysis shows that former Yugoslav countries are clustered at the top and other CEE countries at the bottom, leading to the conclusion that selection bias has been present in many studies on party membership that only included a limited number of post ‑communist countries. In order to explain higher levels of party membership in post ‑Yugoslav countries, we test three sets of explanatory variables, namely socialism, nationalism and clientelism. This exploratory study suggests that nationalist movements from the early period of transition, coupled with clientelistic politics, could serve as the most convincing explanation of high membership density in former Yugoslav countries.
Populist attitudes in Croatia: first analysis with notes on conceptualisation and measurement
Authors: Bartul Vuksan-Ćusa
Published: April 2023

This paper analyses individual-level populism in Croatia. Starting from the ideational definition of populism, the study tests to what extent the economic grievances, sociocultural and ideational explanations, respectively, reflect the average populism subscriber in Croatia. The analysis was made using hierarchical linear regression based on field survey data from 2020 (n=979). Results show how populism is mostly associated with authoritarianism, conspiratorial thinking and institutional (dis)trust. The economic grievances explanation has only marginal relevance, revealing that sociotropic perception is more important than the socioeconomic position of the individual. Furthermore, the study emphasises the importance of operationalising populism in accordance with the assumed structure of the concept. In the same vein, it is noted that populism on an attitudinal level should be separated from the concepts of thick ideologies. If this is not done with caution, the conclusions drawn are questionable, and the analytical contribution of populism is imprecisely determined.

Authors: Şahin Süleyman Nurullah Adahi , Ipek Metin , Gökçek Mehmet Bariş
Published: April 2023

This study is related to evaluations of the performance and usability evaluations of existing and also newly produced Warm Mixed Asphalt (WMA) additives. Viscosity, softening point, and penetration tests were performed on bitumen with additives without changing the bitumen rate for the additives. For the asphalt concrete, Marshall Stability tests were performed. WMA additives are used to reduce asphalt production temperatures and, consequently, the temperature of the mixture significantly. According to the Marshall Stability test, it was determined that the WMA samples fulfilled values within the local standards. The Hot Mixed Asphalt (HMA) and Warm Mixed Asphalt (WMA) additives were compared as to additive costs and energy savings considering the reduced production temperatures. Additives have great potential to be used in adverse weather conditions and in many countries.

Authors: Ayad Mohamad Jouer Dathan  , Abdul Salam Mehdi Altarif  , Amaar J. Mohammed Al-Taiiy
Published: April 2023

The current study depends on lithofacies analysis of Kolosh Formation at Tigran region in north-eastern Iraq. Depending on the physical criteria as grain size, color, texture, and etc., the formation is divided to five lithofacies: pebbly sandstone, coarse sandstone, graded sandstone, mudstone and shale lithofacies. Several sedimentary cycles and depositional regimes were fixed in the studied section represent by high energy regime as pebbly sandstone and medium to low regime as mudstone and shale lithofacies. Based on the data of lithofacies which compared with hypothetical model of the common turbidity deposits, the formation was deposited in submarine fans environments. The secondary depositional environments of the study section are divided into channel and inner fan environments. The Kolosh Formation in northern Iraq was deposited in an active margin basin when the northeast Arabian Plate collided with the Eurasian plate at the final stages of Neo-Tethys closing, which has resulted in large uplifts and subsidence episodes due to eustatic rises and falls.

Authors: Rezan Qadir Faraj
Published: April 2023

The Mawat ophiolite complex (MOC) is a part of the Zagros Suture Zone, which extends of about 2000 km from southeastern Turkey through northern Syria and Iraq to western and southern Iran. The serpentinite rocks are exposed at Waras area near Betwat village. Serpentinite rocks from this area have been studied to assess their suitability for use as dimension stone. Ten samples were collected in the studied area to establish their physical and mechanical properties. Petrographic studies indicate that the serpentinite rocks in the studied area are composed mostly of serpentine minerals so the results of the color measurement show multiple colors of the studied samples after polishing which are grayish green, greenish black, brownish black, olive brown and dark yellowish green. Physical properties for the studied samples were determined they show low bulk density while the water absorption for all the studied samples except sample (10) show suitability for the interior uses, as well as only the samples (4, 6, 7, 8 and 9) exhibit suitable range of interior and exterior uses. The results of the compressive strength and modulus of rupture of the studied samples are below the requirement. According to the American Standard for Testing and Materials, ASTM C1526-02(2002) the serpentinite rocks from Waras area is not suitable for the use as dimension stone.

Authors: Mohammed. K. A. AL- Janan  , R. Y. J. AL-Salih
Published: April 2023

The investigation of a study of each design included the calculation of its axial magnetic field the magnetization of the lens in addition to the magnetic flux density using Finite Element Method (FEM) at three different values of current density (σ = 2,4 and 6 A/mm2). So clearest values and behavior have been obtained at the value current density of (2 A/mm2). It is found that the best magnetizing properties, the highest value of magnetic flux and the lowest value of band width of the axial magnetic field strength have been obtained when the pole head shape length was of (1 mm). The effect of current density on the optical properties has been also studied, and it is found that optical properties have been improved also, and chromatic and spherical aberration values have been decreased significantly. Thus, lens was chosen as the best design among the proposed designs.

Authors: Nibras M. Ibrahim  , Bakr A. Kareem
Published: April 2023

The potable water declined after the global climate crisis. Due to global warming. River levels have also decreased. Moreover, so much has become dependent on the water from the wells. Which are often salty. Purifying this water often requires many fossil fuels that cause damage to the environment. Therefore, the researchers turned to renewable energy sources, including solar energy. In this paper, we designed and made a solar distiller, a single sink with a double slope. It is used to desalinate water and remove salt from water using solar energy. This technique is the best solution for obtaining water in remote and desert areas where potable water is not available. The purpose of the research is to study variables that promote increased efficiency. Study the use of phase change materials (PCM) to enhance the productivity of solar distillers. Bitumen was used to store solar thermal energy in latent heat. It has increased efficiency by (15–25%). For the distiller using bitumen in the basin relative to the distiller to which it is not added.

Published: April 2023

In this paper, three criteria scheduling problem of n jobs on a single machine is considered. Each of these n jobs is to be processed without interruption and becomes available for processing at time zero. The problem is to minimize three objectives simultaneously, which are the completion time, maximum tardiness, and maximum earliness. Here, we develop a fuzzy multi-objective linear programming (FMOLP) model for solving multi-objective scheduling problem in a fuzzy environment by using piecewise linear membership function (PLMF). A numerical example demonstrates the feasibility of applying the proposed model to scheduling problem, and yields a compromised solution to help the decision maker’s overall levels of satisfaction. The algorithm is tested to show the ability of applying this model to three criteria.

Published: April 2023

Objective: It is well known that breast cancer have many impacts on women’s personal and professional life; therefore, this study sought to explore the experience of newly diagnosed women with breast cancer in Oman. This study would help to understand women’s knowledge, attitudes, views, beliefs with breast cancer and to understand the impact of breast cancer on their daily life. Methods: This study used a qualitative design, guided by a constructivist grounded theory approach. Semi-structured interviews with 20 women were conducted in the North Batinah Governorate of Oman. At the beginning of the data collection, purposive sampling relied on inclusion criteria was used. Then theoretical sampling was applied up to the point of data saturation. Results: The data from the interviews underwent constant comparative analysis and two main categories emerged from the data: “Knowing Breast Cancer” and “Being a Woman with Breast Cancer”. The data revealed that many women (60%) had poor understanding on breast cancer and they did not know the risk factors and warning signs of breast cancer. The data also revealed that majority of women (80%) knew the importance of conducting breast self-examination but they did not perform breast self-examination because of their busy life. Also, the data showed that clinical breast examination was conducted rarely within the healthcare institutions and it was limited for those women who had warning signs of breast cancer. The daily life of women diagnosed with breast cancer was within the framework of anxiety. Many women expressed their worrying feeling about their health condition and their personal and professional life. Conclusion: knowing the experience of women newly diagnosed with breast cancer from different aspects could help to provide the necessary educational and supportive services.

Contracts in labor and civil law: issues of unity and differentiation
Authors:   Irkutsk State University, Komkov S. A.
Published: April 2023

It is noted that the employment contract has historically emerged as a civil contract. It is indicated that in Roman private law it was a contract for the employment of a free person’s labor force for a period under which one person, the locator (from Latin – landlord), placed at the disposal of another, the tenant, his labor force, his labor (operae) for a certain remuneration (hiring a worker, coachman, etc.). The features that distinguish the labor contract from civil law contracts, in particular, the fact that in an employment contract the subject is the work itself, and not its result, as well as the element of subordination of one party to the employment contract to the other. The cases of joint legal regulation of labor relations by the norms of labor and civil law are indicated. The article analyzes such issues as the construction of the so-called “labor agreement”, as well as the issue of representation in labor relations, in particular, cases of concluding an employment contract with a minor employee under the age of fourteen and limiting the civil capacity of an employee who, due to addiction to gambling, alcohol abuse or narcotic drugs, puts his family in a difficult financial situation. position. Cases are established when civil legal relations may arise between the parties to the employment relationship. It is noted that the legal regulation of social and labor relations should not be based on the independence of the person performing labor activity, as this is characteristic of the method of civil law regulation of social relations related to labor. The necessity of applying the developments of civil servants on the invalidity of transactions to labor contracts and the implementation of the principle of good faith, which determines, among other things, the inadmissibility of abuse of law, is indicated. The conclusion is substantiated that the establishment of unifying signs of labor and civil law contracts corresponds to the practice of applying labor law norms and contributes to the development of the science of labor law.

Published: April 2023

The article is dedicated to the comprehention of the existing conclusion contract’s patterns. A number of the Civil Code of the Russian Federation’s rules, including art. 433 and art. 434 (point 1, paragraph 2), other rules concerning the process conclusion of a contract – art. 1017 (points 2, 3), art. 1234 (points 1, 2), art. 1235 (points 1, 2) – was analysed. Questions of the necessary grounds of the conclusion a contract (offer, acceptance, passing a property), the act of registration in a contract, the contract’s form are scrutinized. A number of inferences was made, in particular: a) consensual contract and real contract are two basic conclusion contract’s patterns, they can be complicated because of additional demands from the law or participants of a contract (of registration various objects – main obligatory bargain, act of passing a property or consequence of such an act, of agreed by the participants contract’s formalization); b) contract’s form has two sides, because it can be defined by the law or by an agreement, so form influences upon the concluded contract’s quality or upon the quality the process of concluding a contract; c) the rules of the art. 433 and art. 434 (point 1, paragraph 2) are universal and concern not only obligatory contracts, but disposal ones also; d) the moment of concluding a contract is defined by the basic pattern with taking into consideration complicating this pattern demands; e) the process of concluding a contract is a factual composition with various combination of elements (stages), which are accumulated gradually or in a free style. Inferences are made with taking into consideration legal amendments, illustrated by the examples of the concrete contracts.

Russian Russian legislation development slowdown in the Horde period was objective and did not contribute to the improvement of criminal law, laid down in the first legislative monuments of Ancient Russia – Russkaya Pravda and its derivatives. The formation of a Russian centralized state opens a new page in the development of domestic law. In the conditions of feudal fragmentation, a variety of legal regulation has developed, regional legal acts have appeared (Pskov, Dvinskaya and Belozersk court certificates). Centralization required the creation of uniform legal norms and laws, which was reflected in the Judicial Regulations of this period, the analysis of the provisions of which allows you to see of legal principles for cities and their absence for forests and fields. Attention is drawn to the increase in the number of arson attacks due to the social stratification and enslavement of peasants, who have chosen the form of struggle against feudal lords, the arson of their estates. Turning to the study of historical legal experience allows us to recreate a more complete and objective picture of the formation and development of Russian legislation, including such a phenomenon as arson.

Convolutional Neural Networks (CNNs) perform well compared to other deep learning models in image recognition, especially in handwritten alphabetic numeral datasets. CNN's challenging task is to find an architecture with the right hyperparameters. Usually, this activity is done by trial and error. A genetic algorithm (GA) has been widely used for automatic hyperparameter optimization. However, the original GA with fixed chromosome length allows for suboptimal solution results because CNN has a variable number of hyperparameters depending on the depth of the model. Previous work proposed variable chromosome lengths to overcome the drawbacks of native GA. This paper proposes a variable length GA by adding global hyperparameters, namely optimizer and learning speed, to systematically and automatically tune CNN hyperparameters to improve performance. We optimize seven hyperparameters, such as the learning rate. Optimizer, kernel, filter, activation function, number of layers and pooling. The experimental results show that a population of 25 produces the best fitness value and average fitness. In addition, the comparison results show that the proposed model is superior to the basic model based on accuracy. The experimental results show that the proposed model is about 99.18% higher than the baseline model.

A pandemic epidemic called the coronavirus (COVID-19) has already afflicted people all across the world. Radiologists can visually detect coronavirus infection using a chest X-ray. This study examines two methods for categorizing COVID-19 patients based on chest x-rays: pure deep learning and traditional machine learning. In the first model, three deep learning classifiers' decisions are combined using two distinct decision fusion strategies (majority voting and Bayes optimal). To enhance classification performance, the second model merges the ideas of decision and feature fusion. Using the fusion procedure, feature vectors from deep learning models generate a feature set. The classification metrics of conventional machine learning classifiers were then optimized using a voting classifier. The first proposed model performs better than the second model when it concerns diagnosing binary and multiclass classification. The first model obtains an AUC of 0.998 for multi-class classification and 0.9755 for binary classification. The second model obtains a binary classification AUC of 0.9563 and a multiclass classification AUC of 0.968. The suggested models perform better than both the standard learners and state-of-the-art and state-of-the-art methods.

THE RELATIONSHIP BETWEEN HEALTH LITERACY AND VACCINATION STATUS IN PATIENTS WITH DIABETES MELLITUS
Authors: Ersoy Ayşegül , Demirci Hakan
Published: April 2023

Aim: In this study, we aimed to investigate the relationship between health literacy and vaccination status in patients with Diabetes Mellitus (DM). Methods: This research was carried out with 283 volunteer DM patients over the age
of 18 who applied to the Bursa Yuksek Ihtisas Training and Research Hospital between November 2017 and January 2018. The Public Health Literacy Knowledge Scale (PHLKS) was applied to the patients. Results: Of the 283 patients who
participated in the study, 239 (84.50%) declared that they did not get vaccinated because they did not have knowledge about vaccinating diabetics. The number of those who stated that they did not get their vaccinations yet had
the opportunity to be vaccinated was 11 (3.90%). The number of those who said they did not need to be vaccinated because they were not sick was 10 (3.50%). Cronbach's alpha coefficient for the PHLKS scale was calculated as 0.56.
Fasting plasma glucose and HbA1c values were negatively correlated with PHLKS total score (p=0.004 and p=0.046, respectively). The number of hospitalizations in the last 1 year and the PHLKS total score were not related (p=0.137).
PHLKS total score was not associated with hepatitis B vaccination, influenza vaccination, or pneumococcal vaccination (p=0.678, p=0.442 and p=0.221, respectively). Conclusions: The reliability of the PHLKS scale is low. While PHLKS
is associated with blood glucose control, it is not associated with administration of the indicated vaccines. We believe that physicians have a greater role in making vaccines available. Relevant physicians should give necessary
warnings to protect DM patients from these preventable infectious diseases.
