Authors:   Siberian State University of Water Transport, Baranova N.V.
Published: March 2023

The result of the work of the enterprise's supply service directly affects the possibility, rhythm and effectiveness of the carried out production processes. Their natural result is the emergence of a finished product, which has a certain consumer value, which should exceed the total amount of costs incurred by the firm in its manufacture. At the same time, in determining the unit specific value of the produced product, directly attributing to it the costs of the supply service activity presents a certain difficulty. These costs are overhead costs, and their allocation per unit of production assumes the existence of an adequate conditional base of distribution. The purpose of the study in the article – to identify sources, information which may be optimal enough to use in determining the basis for allocation of overhead costs, which are the costs of the supply service. In the process of work were used general scientific methods of research, analysis and synthesis. The study revealed that the most rational is the use of natural indicators, rather than monetary, because the latter are subject to inflationary distortions. The study of the market has shown that the range of requirements of supply specialists is wide enough, taking into account modern trends in automated planning and accounting of supply activities, as well as in the organization of quality management of material movement. Time spent on the performance of functional responsibilities that meet the requirements of the employer, in general, should represent the current list of the currently applicable means of labor standards. However, the available methodological basis of planning the norms of time spent by employees of the supply department is currently outdated, and does not reflect the automation of processes and the expansion of the authority and functionality of employees. At the same time, the methods for determining the optimal size of the staff have not undergone any significant changes and are still relevant. The possibility for the enterprises to use the methodical help of the branch ministries in definition of the time expenses of the employees for performance of the certain kinds of works, allows to show process of occurrence of separate elements as general economic, and general productive expenses, and also to prove the size of these expenses within the limits of calculation actual cost price of unit of production, or the size of average cost price on branch.

The paper explores the use of digital technologies in the recruitment system – one of the management processes of the company. Effective modern recruiting allows the company to avoid financial, time costs, as well as errors related to the human factor, which lead to a negative impact on its financial performance. The use of digital technologies makes it possible to optimize the recruiting system at the enterprise, minimize the subjective impact on the selection and selection of personnel, reduce the complexity of routine operations of recruiters, which in the future significantly increases the competitiveness of organizations in the economic market. Today, a large number of companies are faced with the fact that managers do not fully realize the rationality of the introduction and use of digital technologies in the recruitment and selection system. As a result, applications and systems unsuitable for the specifics of the business are used, which, on the contrary, lead to negative consequences. Thus, the relevance of the study lies, first of all, in the analysis and evaluation of digital technologies in the recruitment system to understand which technologies will be correctly implemented in a particular organization. The article presents a comparative analysis of modern technologies of effective recruiting, considers the stages of recruitment development, options for using digital technologies in the recruitment process, the capabilities of ATS systems, the types of HR bots in the recruitment of personnel, as well as the difficulties of implementing digital technologies.

Characterization of the VKORC1 and CYP2C9 genotypes v2
Authors: Causevic Mirsada
Published: March 2023

Vitamin K antagonists (e.g. warfarin) are anticoagulants which represent widely prescribed drugs for prevention and treatment of thromboembolic disorders. Warfarin's molecular target is vitamin K epoxide reductase enzyme and its metabolism is performed by the cytochrome P-450 2C9 enzyme, both of which are encoded by polymorphic genes - vitamin K epoxide reductase complex subunit 1 (VKORC1) and cytochrome P-450 2C9 (CYP2C9), respectively. Identification of the VKORC1 and CYP2C9 genotypes was recommended by the U.S. Food and Drug Administration in 2007, in order to guide the initial dosing of warfarin, the first oral vitamin K antagonist drug, to achieve the optimum anticoagulation and prevent hemorrhagic events. In an effort to provide a lab protocol that will provide training in pharmacogenomics/pharmacogenetics (PGx) for undergraduate students of pharmacology or medicine, that can be performed in a laboratory that contains basic molecular biology equipment and by using reagents that are available worldwide at low cost, we revisited protocols published previously by other researchers. We hope that it will provide the elementary understanding of the simplest molecular biology methods used to identify different VKORC1 (-1639G>A) and CYP2C9 genotypes, as well as understanding of a link between a specific genotype (or combination of genotypes) and phenotype relevant for a patient’s drug response. The protocol represents a step-by-step guide to using polymerase chain reaction restriction fragment length polymorphism (PCR-RFLP) method in determining VKORC1 -1639G>A, CYP2C9*1/*1, CYP2C9*1/*2, CYP2C9*1/*3, and CYP2C9*2/*3 genotypes. Based on the combination of the VKORC1 -1639G>A and CYP2C9 genotypes, that is, the pattern of DNA fragments observed at the end of an experiment, which are visualized using agarose gel electrophoresis and DNA staining, a conclusion on an individual’s sensitivity to warfarin and appropriate drug dose is reached.
The Relationship Between Chinese EFL Learners’ Learning Anxiety and Enjoyment in a Blended Learning Environment
Authors: Chen Jing , Kim Hyun-Ju
Published: March 2023

For the past two decades, learner psychology in relation to second language acquisition (SLA) has been a hot topic, and negative emotional variables in students’ language learning have attracted a lot of attention. More recently, focus has shifted to a positive emotion, enjoyment, and its relationship with anxiety. The present mixed-method study investigated the levels of FLCA and FLE of 228 Chinese EFL learners, the correlations between the two and the sources evoking these two emotions in a blended learning environment. Considering the questionnaire’s findings, participants reported relatively high levels of FLE (Mean=3.53, SD=.61) and low levels of FLCA (Mean=3.12, SD=.42). There was no significant correlation between FLCA and FLE, according to correlation analysis. Additionally, a qualitative investigation of students’ emotional experiences found that FLCA was more closely tied to learner-internal factors while FLE was to the teacher. The conclusions have pedagogical ramifications for EFL teaching in China’s educational system.

Authors: Chen Shiyue , Mansor Nor Shahila , Mooisan Chin , Abdullah Muhammad Alif Redzuan
Published: March 2023

The steady growth of tourism is increasing the demand for tourism translation. Cultural words (CWs) translation is challenging since they are absent from target cultures. This systematic review examines studies on CWs translation in tourism texts to comprehend the literature and explore future research tendencies. Following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses, researchers did a comprehensive literature review. Twenty-one articles met the inclusion criteria after the protocol-required data selection and screening. The findings reveal that scholars are increasingly concerned with CWs translation in tourism texts. Moreover, all the included articles used varied theories. Most of them focused on applying various taxonomies of translation strategies to compensate for the losses of cultural connotations in cultural words' rendition. Besides, other researchers focused on CWs translation from different perspectives, such as translation quality assessment, Eco-translatology, meaning equivalence, cultural manipulation, and relevance theory.
Children’s Literature: The Significance and Other Impacts
Authors: Ismail Hisham Muhamad
Published: March 2023

It is worth noting that children’s literature is one of the rapidly growing fields in the literature on one hand, but on the other hand, it is also the most argumentative area of study among critics and all interested persons. The debatable feature of this literary genre underlies the broad scope of the literary texts that can include under its umbrella; fairy tales, short stories, novels, poems, and picture books. Additionally, these books’ commercial success and readability can have a long-lasting influence, and we can trace these impacts from one generation to another and from one culture to another. These books occupy a vital position in the scholar’s discussion to examine the suitability and goodness of their content to fit the mentality of children. No one can deny these books’ profound impacts on the young generation’s personal development, but we must admit that other impacts may scratch this bright image of these memorable books. In this paper, the researcher tries to detect both sides of children’s literature by referring to the role of the writer’s ideology.

Detecting early symptoms of engine failure is a crucial phase in an engine management system to prevent poor driving performance and experience. This paper proposes a Hybrid Electric Vehicle (HEV) engine diagnostics using a low-cost piezo-film sensor, an analysis with improved statistical method and verification by a Support Vector Machine (SVM). The current engine management system is unable to evaluate the performance of each cylinder operation. Eventually, it affects the whole hybrid vehicle system, particularly in the mode of charging and accelerating. This research aims to classify the combustion to monitor the condition of sparking activity of the engine by using the Z-freq statistical method. Piezo-film sensors were mounted on the Internal Combustion Engine (ICE) wall of each hybrid vehicle for vibration signal measurements. The engine runs at different speeds, the vibration signals were then recorded and analysed using the Z-freq technique. A machine learning tool referred to as Support Vector Machine was used to verify the classifications made by the Z-freq technique. A significant correlation was found between the voltage signal and calculated Z-freq coefficient value. Moreover, a good pattern was produced within a consistent value of the engine speed. This technique is useful for the hybrid engine to identify different stages of combustion and enable pattern categorisation of the measured parameters. These improved techniques provide strong evidence based on pattern representation and facilitate the investigator to categorise the measured parameters.

Instant coffee is a popular beverage around the world and has been recognized for shorter preparation time and longer shelf life compared to brewed coffee. The production of instant coffee powder through the drying process requires lots of attention to provide the best quality of coffee to the consumer. Most of the instant coffee powder has been produced either by freeze-drying or spray drying. However, the drying spray showed some advantages in case of shorter drying time, ability to handle in a large capacity, and continuous production of coffee powder compared. The objective of this study is to identify the affecting factors in achieving a high quality of coffee production in the drying process. The initial concentration of coffee extract is between 30-42 wt.% were fed by the atomizer. Also, the spray drying chamber with the inlet air temperature of 423.15 K to 573.15 K. The pressure was set at 52 bar to obtain the best drying quality of the coffee production. The simulation results show with the air temperature of 423.15 K, the pressure of 52 bar and the initial extract concentration of 42% are the best conditions of drying coffee using the spray drying method. Also, the velocity distribution flattened as the flow proceeds downstream. As well, the vapour concentration distribution flattened further down the chamber so that the drying air leaving the drying chamber has almost a uniform moisture distribution.

In this work, the effect of graphene oxide (GO) incorporation into the membrane support layer towards the performance of thin-film composite (TFC) membrane was investigated. The support layer was fabricated by phase inversion method with the incorporation of GO as hydrophilic nanoparticles. Next, the active polyamide layer was formed on the membrane support layer via interfacial polymerization between trimesoyl chloride (TMC) and m-Phenylenediamine (MPD). The cross-section images from Field-Emission Scanning Electron Microscope (FESEM) showed the presence of active polyamide layer on the surface of TFC membrane while the FTIR results indicated the existence of bands associated with the amide linkages. The initial study showed that an optimal amount of GO (0.5 wt%) incorporation into the polymer substrate resulted in favourable improvement in TFC membrane performance. The physical and chemical properties of GO helps in enhancing the water transport through the membrane polymer matrix and thus contributing to higher permeate flux. The TFC-FO membrane incorporated with GO showed 44% improvement in terms of water flux (3.72 compared to 2.09 Lm-2 h-1 for pure PSf membrane) and minimal improvement in reverse solute diffusion (0.02 compared to 0.03 g m-2 h-1 for pure PSf membrane). Thus, this study showed that small addition of GO nanoparticles into the membrane support layer leads to an increase in performance of TFC membrane for FO application.

Crystalline silicon solar cell efficiency is required in order to accurately determine its performance and evaluate the fabrication process. Extensive automation has led to development of expensive instrumentation. In this study, simple, inexpensive method for measuring solar cell efficiency is reported. A controllable direct current (dc) illumination intensity method based on low power xenon arc lamps was designed and constructed. Low resistance electrical contacts were formed with conventional front surface probes and back surface Au-plated metal plate with vacuum attachment. In order to measure current-voltage (I-V) response, variable resistance approach was chosen. Commercially available, low cost electronic loads power supply is used to precisely vary resistance while measuring cell voltage and current. The resistance is controllably varied from a short circuit to an open circuit position on the I-V curve while measuring cell voltage and current. Plotting current as a function of voltage generates the characteristic solar cell I-V response. Solar cell efficiency measurements were recorded and plotted using LabVIEW program. The light intensity was varied by increasing number of high intensity discharge (HID) 50 W from 1 to four in order to vary respective illumination intensities from 330 to 1200 W/m2 range. The variation in light intensity was aimed at investigation of the electronic loads power supply at low and high currents. This I-V tester has been applied to different types of solar cell to validate its performance. Solar cells measured as part of this study included commercial silicon solar cell and laboratory solar cells with phosphorus oxytrichloride (POCl3) and phosphoric acid (H3PO4) emitter formation. This I-V measurement system for commercial cell exhibited an efficiency of 15.83% and efficiency of 16.2% and 13.3% for solar cells with POCl3 and H3PO emitters.

This research was conducted to investigate the suitability of using two models; namely the artificial neural network (ANN) and adaptive system network model Neuro-Fuzzy (ANFIS) methods to predict the flexible pavement layer moduli. The falling weight deflectometer (FWD) data obtained from the Butterworth–Kulim Expressway (BKE) in year 2011 were used to test the models. The ANN and ANFIS models have been trained and tested continuously using different parameters until the optimum output is obtained. Thereafter, a validation process has been carried out to test the ability of whole models by calculating the coefficient of determination (R2), the mean absolute error (MAE), the mean squared error (MSE) and root mean squared error (RMSE). A total of 270 data sets have been used to develop the models. Based on the analysis conducted, it was found that both models are able to predict well the flexible pavement layer moduli(R2 > 0.90). However, a further comparison suggested that the ANFIS model yield a higher precision compared to the ANN model, with lower MAE, MSE and RMSE values. Therefore, it can be inferred that the neural network models have an excellent potential to replace the existing analytical and empirical models in predicting the flexible pavement layer moduli.
Comparative Analysis of CNN Models and Bayesian Optimization-Based Machine Learning Algorithms in Leaf Type Classification
Authors: ASLAN Muhammet Fatih
Published: March 2023

In this study, the leaves are classified by various Machine Learning (ML) and Deep Learning (DL) based Convolutional Neural Networks (CNN) methods. In the proposed method, first, image pre-processing is performed to increase the accuracy of the posterior process. The obtained image is a grayscale image without noise as a result of the pre-processing. These preprocessed images are used in classification with ML and DL. The Speeded Up Robust Features (SURF) are extracted from the grayscale image for ML-based learning. The features are restructured as visual words using the Bag of Visual Words (BoVW) method. Then, histograms are generated for each image according to the frequency of the visual word. Those histograms represent the new feature data. The histogram features are classified by four different ML methods, Decision Tree (DT), k-Nearest Neighbor (KNN), Naive Bayes (NB) and Support Vector Machine (SVM). Before using the ML methods, Bayesian Optimization (BO) method, which is one of the Hyperparameter Optimization (HO) algorithms, is applied to determine hyperparameters. In the classification process performed with four different ML algorithms, the best accuracy is achieved with the KNN algorithm as 98.09%. Resnet18, ResNet50, MobileNet, GoogLeNet, DenseNet, which are state-of-the-art CNN architectures, are used for DL-based learning. CNN models have higher accuracy than ML algorithms.
THE ROLE OF THE UKRAINE-CENTRIC ELITES IN THE CONTEXT OF THE PHILOSOPHY OF THE OF UKRAINE'S SUBJECTIVITY (DEDICATED TO THE 300TH ANNIVERSARY OF BIRTH OF HRYHORIY SKOVORODA)

The article analyzes the role of Ukrainian elites in the light of the problem and philosophy of subjectivity. Attention is focused on the specifics of this moment in the existence of the Ukrainian state and nation, which are waging a fierce struggle for their own freedom and survival in the war with the Russian fascist regime. It is emphasized that subjectivity in modern scientific discourse means the level of independence and independence from external factors of the country, its self -sufficiency and independence as an actor of history. From a philosophical point of view, a subject in a broad sense is that or that which/who has agency, i.e. acts on some other entity (object), or has dominion over it. In this case, something/someone is endowed with subjectivity. When defining subjectivity, the emphasis is placed on the country as a unity of the state, nation and community of citizens who inhabit this country. Today, the reality is that as a result of the heroic resistance of the Ukrainian nation to the aggression of the Russian Federation, the status of Ukraine as an actor in history is fundamentally changing. She turned into a leader of the free world, becoming a defender of authentic European values, which the modern West, especially Western Europe, has largely destroyed. It is worth agreeing with the statement of the famous political analyst A. Piontkovsky that it is Ukraine today that is saving Europe and the whole world from the plague of rashism and totalitarianism already in the 21st century. Its position is the position of an active subject, the center of reformatting of European politics, which cannot help but influence the entire world today. It is concluded that the activity of Ukrainian-centric elites in Ukraine is a necessary condition for winning the war against the rashist aggressor. In addition, the realities of the war require the actual transformation of all existing elites in the state into Ukrainian-centric ones. The formation of a strong subjectivity of Ukraine also depends on the ability of its elites to adequately respond to the challenges and threats facing the Ukrainian nation. The article is dedicated to the 300th anniversary of the birth of the outstanding Ukrainian philosopher Hryhorii Savych Skovoroda.
THE PROBLEM OF CRIMEA TATAR AUTONOMY IN UKRAINE
Authors:   H. Skovoroda Institute of Philosophy of the National Academy of Sciences of Ukraine, Kyiv Ukraine, HRABOVSKY Serhiy
Published: March 2023

The article is devoted to the actual theoretical and practical problem of today - the creation of Crimean Tatar autonomy. The author responds to the discussions about this problem, which have flared up in the intellectual space of Ukraine in recent months, and offers his view on it. The article analyzes in detail the arguments of opponents of the creation of such autonomy and proves that these arguments are based either on ignorance of historical and political facts, or are based on a deliberate distortion of reality. The Crimean Tatars (Crimeans, Cyrimly) are, according to the law, one of the three indigenous peoples of Ukraine, and according to history, they are a state-creating nation. In 1917-18, the Crimean Tatars attempted to build an independent state on modern foundations. This attempt was destroyed first by the "Red" and then by the "White" Russians. In 1921, the Bolsheviks were forced to create an autonomous republic in Crimea within the borders of Russia in order to ensure the national needs of the Crimean Tatars. In 1928, 1937-38 and 1944, the Crimean Tatars became victims of mass repressions, the last time – victims of deportation and genocide. The author emphasizes that upon returning to Crimea, the Crimeans became one of the main pillars of Ukraine on the peninsula in the fight against Russia's attempts to annex Crimea. In 2014, official Kyiv betrayed the Crimean Tatars, who were ready to oppose Russia with weapons in their hands, and in 2016 it prevented the formation of the Crimean Tatar volunteer battalion. Therefore, the creation of Crimean Tatar autonomy is not only the realization of the legal right of the Cyrimly as an indigenous people, but also the atonement of the guilt committed by the official Kyiv against the Crimean Tatars. Instead, denying the need to create such autonomy or ignoring the need for it can seriously undermine Ukraine's position both in Crimea and in the entire Turkic world.

Purpose of article is the disclosure of Roman Ingarden's aesthetic methodology as an important basis for the analysis of religious art. Methodology of the research is to use the phenomenological method of Roman Ingarden as a methodological basis in the analysis of religious art in the paradigmatic dimension of Religious Science. For the first time, the methodological potential of the aesthetic concepts of the Polish phenomenologist Roman Ingarden in the study of religious art on the example of the Armenian Cathedral of Saint James in Jerusalem as an example of an architectural narrative has been proved. In particular, separate phases of the aesthetic experience, which is based on religious values: an introductory emotion (entrance to the architectural complex, immersion in the buried light of the temple space), the constitution of the aesthetic object (iconography, decoration, the basilical structure of the building, the throne of Saint James, the relics of James the Greater and James, brother of the Lord); contemplation of the subject of perception and emotional “response” after recognizing its value (comprehension of the Christian message of this place, understanding of life as a pilgrimage to eternity, internal personal change of man, catharsis). The phenomenological theory of Roman Ingarden can be used in the study of religious art with a structured allocation of its content, which implicitly contains aesthetically marked axiological dominant, whose verification is possible through the analysis of certain artistic means of the corresponding art form. In further studies in religious studies (this may also apply to studies in aesthetics or cultural theory), it is advisable to trace other angles of the philosophical and aesthetic teaching of Roman Ingarden, which creates a heuristic space for a wellfounded interpretation of works of religious art, which is especially important for their understanding not only by scientists, but also and believers in acts of communication with the supernatural, a deeper understanding of religious practices and sacred worship.

Honoring the memory of Hryhoriy Savych Skovoroda in the anniversary year of his birthday, we can talk about the eternal, inexhaustible potential of his creativity and ideas, which are endowed with the category of timeless, gaining new meanings in every era for almost three centuries. The life and philosophical and literary heritage of H. Skovoroda (which are complementary in terms of content, because he included reflections on the meaning of life in his works) have been repeatedly studied by scientists from different points of view. They became the subject of understanding in the literary and artistic works of many writers and poets, including Pavlo Hryhorovych Tychyna. In this article, the authors attempted to analyze the polyphonic motifs of the poem-symphony of the Ukrainian poet P. Tychyna "Skovoroda", and drew attention to its national-philosophical sound. The very genre of the work – a symphony – is seen as interesting, which is fully justified by its construction and sound characteristics (as is known, P. Tychyna is the creator of many "musical" poems, as he had an extremely fine sense of sound rhythm, to which he skillfully selected verbal forms). The main leitmotif of the work is the idea of learning and finding one's place in society and the world. Probably every person has thought about the question of truth, "correct expediency" of the own life. H. Skovoroda put these aspirations into a laconic saying that has already become a maxim over the centuries - "Know yourself." The thought searches, hesitations and formation of the philosopher's beliefs described by the artist take place against the background of the national space and reality, which were native to him, and he valued communication with "the people" above all else, as well as personal freedom, because only by being free can one be truthful, frank and sincere. H. Skovoroda affirmed this creed with another leading idea of his life - "the world was catching me, but I didn't catch it." These words are engraved on his grave.

Process optimisation in production is an integral part of management in all companies. Given the constantly increasing pressure from customers, companies are forced to take steps to satisfy them. These steps include, above all, increasing production capacities and optimising production and service processes while maintaining or minimising all costs. The changes implemented today should be oriented towards modern trends in the field of lean manufacturing and Industry 4.0. However, companies cannot optimise all processes at once due to costly investments to implement the relevant changes. The paper contains an analysis of the shipping process in a selected company, which is also focused on assessing the implementation of business orders, storage and assembly of finished steel shapes. Based on the identified problems, this article aims to propose optimising the dispatch process, even concerning whole implementation process of business orders.

This paper discusses a suitable method to manufacture contactor forgings, depending on the size of the series. A suitable semi-finished product and the method of cutting have been proposed. The design of a suitable forming machine and forging tools was carried out for the production of contactor forgings in the number of 10,000 pieces and 50,000 pieces per year. The LE 160 eccentric press was designed to cut the sprue. A comparison was made between the production of contactor forging on the pneumatic-hydraulic hammer KHZ 4 A and the production on the mechanical crank press LKM 1600. The die design was carried out for both production alternatives. The cost analysis for the production of one piece of forging showed that for a large number of pieces, it is more economical to forge using a mechanical forging press.

The article deals with the analysis of the unconventional pressing process of metallic materials by twist channel angular pressing (TCAP) method. TCAP process is a modification of the equal channel angular pressing (ECAP) forming method, which can be used to prepare bulk materials with an ultra fine-grained structure. Simulation of the TCAP process is an important source of information on the effect of design and technological parameters on the grain refinement efficiency. The TCAP process was simulated using 3D finite element method (FEM).
