Authors: Şimşek Dağistan , Oğul Burak , Abdullayev Fahreddin
Published: September 2024

Discrete-time systems are sometimes used to explain natural phenomena that
happen in nonlinear sciences. We study the periodicity, boundedness,
oscillation, stability, and certain exact solutions of nonlinear difference
equations of generalized order in this paper. Using the standard iteration
method, exact solutions are obtained. Some well-known theorems are used to
test the stability of the equilibrium points. Some numerical examples are
also provided to confirm the theoretical work?s validity. The numerical
component is implemented with Wolfram Mathematica. The method presented may
be simply applied to other rational recursive issues. In this research, we
examine the qualitative behavior of rational recursive sequences provided
that the initial conditions are arbitrary real numbers. We examine the
behavior of solutions on graphs according to the state of their initial
value xn+1 = xn?2xn?8xn?14/?xn?5xn?11 ? xn?2xn?5xn?8xn?11xn?14.
Hand replantation surgery in regional anesthesia - report of two cases
Authors: Milosavljevic Ana
Published: September 2024

Introduction. Hand replantation is a microsurgical operation on completely or incompletely amputated hand during which the soft tissue and bone structures are reanastomosed and reconstructed. Blockade of peripheral nerves provides anesthesia and analgesia, but also a sympatholytic effect, improving blood flow and offering better perfusion of the replanted tissue. The aim of this paper is to show the importance of regional anesthesia for hand replantation surgery. Case report. Two male patients sustained a traumatic amputation of the hands by working on industrial machines. The patients underwent a microsurgical hand replantation. An ultrasound-guided brachial plexus block was performed through an axillary approach. A 22G, 10 cm needle was used. Bupivacaine 0.25% 30 ml and lidocaine 1.3% 30 ml without adrenaline were injected perineurally. The medial side of the upper arm was infiltrated with lidocaine since it is the area of intercostobrachial nerve innervation that remains unaffected by the brachial plexus block, preventing the pain caused by the pressure from the tourniquet. During the operation, the patients were sedated with midazolam. Postoperatively, the patients were under observation at the Intensive Care Unit. Analgesia was maintained with intravenous nonsteroidal anti-inflammatory drugs and tramadol, and a single-shot blockade of brachial plexus, intramuscular groove approach. Laboratory tests were conducted, and every three hours, the skin color and turgor, capillary refill, and tactile temperature were monitored. Conclusion. Reducing peripheral vascular resistance, preventing vasospasm, and increasing blood flow through the anastomoses increase the chance of successful replantation and reduce postoperative pain and anxiety, which overall affect patients function and comfort.

Background and purpose: Hip dysplasia can present challenges for total hip arthroplasty (THA) due to anatomic abnormalities. We aimed to assess the association of age, sex, osteotomies prior to THA, and fixation method on 5- and 10-year revision-free implant survival and patient-reported outcome measures (PROMs) of THAs in patients with hip dysplasia.Methods: Using Dutch Arthroplasty Register data, we studied hip dysplasia patients receiving primary THAs in 2007–2021 (n = 7,465). THAs were categorized by age, pelvic osteotomy prior to THA (yes/no), and fixation (cemented, uncemented, hybrid, reverse hybrid). Kaplan–Meier and multivariable Cox models were used to determine 5- and 10-year revision-free implant survival and adjusted hazard ratios including 95% confidence intervals (CIs). Reasons for revision and PROMs were compared within the categories.Results: We found a 10-year revision-free implant survival of 94.9% (CI 94.3–95.5). Patients younger than 50 years had a 10-year implant survival of 93.3% (CI 91.9–94.7), Patients with prior pelvic osteotomy had a 10-year implant survival of 92.0% (CI 89.8–94.2). Fixation method and sex were not associated with implant survival. Patients with a prior pelvic osteotomy had more revisions due to cup loosening and reported lower PROM scores than patients without earlier osteotomy.Conclusion: 5- and 10-year revision-free implant survival rates of THA for hip dysplasia are 96.4% and 94.9%. Age and prior osteotomies were associated with decreased implant survival rates in patients with hip dysplasia, while fixation method was not. Prior osteotomies were also associated with reduced PROM scores.

Authors: Kjærgaard Kristian , Yilmaz Sibel , Kaptein Bart , Overgaard Søren , Ding Ming
Published: September 2024

Background and purpose: The low-dose EOS Imaging System is an emerging tool for 3-dimensional measurements in orthopedics. The clinical feasibility for measuring total hip arthroplasty (THA) liner wear has not yet been investigated. We aimed to evaluate the feasibility of using EOS to measure THA liner wear by examining the experimental accuracy using a THA phantom and clinical precision of patients with THA, considering a clinically relevant precision at the 95% repeatability limit to be 0.2 mm.Methods: An experimental THA phantom with movable stem and a fixed cup with a plastic liner was constructed to simulate progressive 3D liner wear. Series of 11 pairs of radiographs with 50 μm femoral movement in between were obtained for each 3D axis in EOS. 30 patients with a THA were scanned twice using EOS to assess precision. Model-based radiostereometric analysis (RSA) was used for wear measurement.Results: The mean difference (true minus simulated wear) with standard deviation (SD) and 95% limits of agreement for experimental THA wear were 0.005 (0.037) and [–0.069 to 0.079] mm for the vertical (y) axis. The mean (SD) and 95% repeatability limit for precision for clinical measurement were –0.029 (0.105) and 0.218 mm.Conclusion: Experimental THA liner wear using EOS was within clinically relevant tolerances and without bias. The clinical precision was just outside our defined clinically relevant precision. Compared with conventional RSA, EOS is less accurate and precise but may still be of value for certain clinical applications, provided larger sample size or longer follow-up are available.
On the influence of microstructure evolution and wear mechanism of direct laser deposited Ti-Al-Si coatings with different Si contents
Authors: Chen Xueting , Li Yu , Wei Wei , Yin Guili , Yang Lin , Su Hai
Published: September 2024

In response to the problem of low hardness and poor wear resistance of TC4 coatings prepared by laser additive manufacturing, three titanium alloy coatings with different Si contents were prepared on a TC4 substrate by direct laser deposition (DLD) technology. The evolution of the microstructure and wear mechanism of the coatings were studied. The addition of the Si element facilitated the formation of Ti5Si3 hard phase, which exhibited a uniform mesh form. The strengthening effect of the hard phase in the prepared coating increased with its proportion, demonstrating a positive correlation with the incremental addition of an Si element. However, the excessive addition of the Si element resulted in the surface cracking of the coating. The optimal DLD Ti-Al-Si coating was obtained when the Si content was 10 wt. %, with an average microhardness of 801 ± 24 HV0.2, 2.5 times greater than that of the TC4 substrate. The average friction coefficient of the Ti-Al-Si coating was 0.39, and the wear rate was 1.9%. The hard phase was uniformly distributed in a mesh form, which not only refined the wear debris and suppressed the shear force of the wear debris during wear but also slowed down the continuous wear of debris on the worn surface. The results of this study could provide a reference for preparing high-hardness and wear-resistant titanium alloy coatings by DLD.
R2 METRIC DYNAMICS FOR K-NEAREST NEIGHBORS REGRESSION MODEL TRAINED ON SERIES OF DIFFERENT SIZES
Authors:   State University of Intellectual Technologies and Telecommunications, Babich Yu. , Hlazunova L. , Kalinina T. , Petrovych Y.
Published: September 2024

An R2 score or a coefficient of determination is used often as a metric to evaluate regression models. It can be applied solely but usually it is combined with other metrics in order to increase accuracy of a model evaluation. The goal of the work is to research the dynamics of the R2 score of a K-Nearest Neighbors regression model trained on series of different sizes in order to propose a new approach to increase the robustness and accuracy of the model evaluation when the R2 score metric is used solely. Typically, a value of the R2 score metric above 0.8 is considered to be sufficient while an evaluated model is considered to be accurate enough. However, such a way of R2 score interpretation to may lead to model’s accuracy misevaluation, which is shown in the proposed paper. The results obtained clearly display that R2 score can vary significantly in some cases depending on the samples selected to test part of a series used for model evaluation. The mentioned variation can contribute to model’s accuracy overestimation, which, in turn can lead to incorrect results of model application. The known methods to make model estimation more accurate involve use of other metrics. Instead, this paper focuses on increase of model’s accuracy estimation without the necessity of using other metrics. The R2 score dynamics is examined using 25000 cycles of the K-Nearest Neighbors regression model training and evaluation. Selection of samples to a training or test part of a series has been done randomly. For all the experiments quantity of neighbors is fixed and equals to the default value of n_neighbors=5 of the KNeighborsRegressor method provided by the Sklearn library. The paper both states and proves a hypothesis that the R2 score variation is expected to increase with series size reduction and the variation is supposed to be observed for models trained on the same series because of training/test samples selection randomness. The experiments carried out allowed to propose an alternative approach that did not require any supplementary metrics. The proposed approach considers application of the R2 score along with its variation that must not exceed 0.2 for the K-Nearest Neighbors regression model.
SEARCH FOR A DATA TRANSMISSION ROUTE IN A WIRELESS SENSOR NETWORK USING A GENETIC ALGORITHM
Authors:   Lviv Polytechnic National University, Pyrih Ya.
Published: September 2024

The article is devoted to the application of a genetic algorithm for determining the optimal route in a wireless sensor network. The paper presents a classification of data routing strategies based on: the method of determining routes, network structure, network operations, and communication organiser. The genetic algorithm is classified as a multi-path routing strategy, since its use allows obtaining a set of routes. Accordingly, when data transmission via the best route is not possible, information from a set of routes is available, which allows obtaining alternative solutions in case of failure of the main route. The main stages of the genetic algorithm are presented: selection, crossing and mutation, with considerable attention paid to setting its parameters, in particular, population size, number of generations, crossover probability and mutation probability. To determine the route in a wireless sensor network, the following set of genetic operators is used: a tournament selection operator, an ordered crossover operator, and a mixing mutation operator, and a function is formed to assess the fitness of each individual (route). To test the performance of the presented genetic algorithm, a software product in the Python programming language was developed using the DEAP library. A network of 25 nodes was modelled, randomly placed on a 100 by 100 area, with each node having a range of 30 metres. To take into account the impossibility of data transmission between nodes with a greater range than the specified one, a distance penalty of 1000 metres is used, which encourages the genetic algorithm to search for shorter routes. The matrix of nodes of the considered network is presented, which contains information about the topology and relationships between nodes. Based on the results of simulation modelling, it is shown that the shortest route between the two considered nodes is established at a number of generations of 150 and a population size of 300. The results also demonstrate a linear increase in the route search time with an increase in the number of generations and population size.
WAYS TO COMPREHENSIVELY ENSURE THE ACCURACY AND NOISE IMMUNITY OF RADAR SYSTEMS FOR AUTONOMOUS NAVIGATION AND TO PREVENT COLLISIONS OF GROUND MOVING OBJECTS
Authors:   Lviv Polytechnic National University, Budaretskyi Yu. , Dzyuba A. , Klymash M. ,   Lviv Polytechnic National University
Published: September 2024

Modern navigation equipment should make it possible to determine in real-time the location of a ground-moving object (NRA) and the direction of its movement. To solve such problems, the equipment of consumers (AS) of satellite radio navigation systems (SRNS) is widely used. However, a number of circumstances, such as traffic in tunnels, and forests, within dense urban areas, the presence of natural and man-made radio interference, do not provide continuous reception of information from the necessary grouping of navigation Satellites. Therefore, for continuous navigation, NRAs are supplemented with autonomous navigation tools. In recent times, inertial means of autonomous navigation have been widely developed. The introduction of MEMS technologies and devices that combine microelectronic and micromechanical components has made it possible to create a wide range of small-sized sensors, such as accelerometers, angular velocity sensors, gyroscopes, and magnetometric sensors. The development of microwave technologies has made it possible to create small-sized radar sensors, which determine the further development of odometric navigation tools. Radar sensors play a special role in collision avoidance systems for NRA movement in columns and in conditions of limited optical visibility. Creating autonomous navigation systems based on such sensors is an urgent scientific and technical task. Radar meters based on the Doppler effect are all-weather and round-the-clock tools for a comprehensive system technical solution to this problem. The Doppler sensitivity of the meters significantly depends on the frequency of operation of the receiving and transmitting equipment, the maximum of which is reached in the millimeter frequency range. Taking into account the circumstances mentioned above, as well as the relatively high price of radar equipment, an important scientific and practical problem is the maximum unification of technical solutions for the construction of meters, namely: the choice of circuitry, element base and materials; development of test methodology, composition of spare tools and devices, operational documentation. An analysis of the tasks solved by radar meters of NRA motion parameters for their autonomous navigation and for ensuring traffic safety in columns and on rough terrain, namely, the prevention of collision with obstacles in conditions of limited optical visibility, was carried out. Radar methods of autonomous navigation and collision avoidance are analyzed, their disadvantages and advantages are indicated, proposals for solving the issues of improving the accuracy and noise immunity of radar meters are formed.

The informative signal of the vast majority of sensors on piezoelectric transducers is the ToF (Time-of-Flight) of ultrasonic oscillations, and its formation is realized by measuring the delay between the pulses of oscillations emitted by the actuator and the pulses of these oscillations received by the sensor. However, the processes of forming this informative signal and the electronic means of implementing these processes are characterized by a significant influence of extraneous factors, the compensation of which is largely problematic. Following this problem, this work solves the problem of embedded self-diagnosis of piezoelectric sensors signal converters. Methods of intellectualization of measurement processes are used based on the redundancy theory and its further development in the field of redundancy information theory, measuring technology, and sensors. It is proposed to supplement the input signal path of the sensor device with a specialized circuit for activating self-oscillations of the piezoelectric transducer. The proposed method is based on the monitoring of transient processes and oscillations at the frequency of natural oscillations of piezoelectric transducers during periodic switching of the latter to the input of the transimpedance amplifier TIA. In accordance with the proposed solution, the transimpedance amplifier is used to form damping self-oscillations, the frequency, amplitude and decay rate of which are monitored by the drift of the parameters of the piezoelectric transducer. The task of optimizing the operation modes of the circuit unit based on the transimpedance amplifier based on the criterion of maximum efficiency in the formation of an informative signal of the stability of the operation of piezoelectric transducers has been solved. The signal path of the built-in system of ultrasonic piezoelectric sensors with the self-diagnosis function UCQD (U-sound Front-end with in-situ CQ Diagnostic) is implemented using a programmable system on a PSoC (Programmable System on Chip) PSoC 5LP series (Cypres, Infineon Technologies).

This allows for more accurate predictions and informed decisions based on real data, contributing improving of medical services and patient care quality. The research results underscore the potential of machine learning methods in healthcare institutions to enhance predictive accuracy and decision-making. Future research directions may include exploring additional feature engineering methods and using advanced machine learning algorithms to further increase the utility of clinical IoT data analytics. In particular, exploring the possibilities of deep learning and neural networks may open new horizons for clinical data analysis and processing.
The Practice of Transferring Land Ownership to a Pawn Agreement from the Perspective of Sharia Economic Law
Authors: Faizal Liky , Tamza Fristia Berdian
Published: September 2024

Receivable debt agreement, the rahin party binds the pledge guarantee in the form of a Notarial Deed of PPAT which is authorized to make a pledge agreement contract. The lien agreement is usually only carried out by binding collateral to ensure that rahin does not default on receivables given by the murtahin. However, in this agreement, the rahin party immediately promised to transfer land ownership to the murtahin party if the rahin party was unable to pay off the debt. This transfer provision, in substance, is not found in the concept of fiqh muamalah, but the rahin party only guarantees land (marhun) as collateral for debt. The focus of the problem in this study is what is the view of Islamic law on the agreement to transfer land guarantees for receivables? Meanwhile, the purpose of this study is the contract of transferring land ownership to a pawn contract from the perspective of shari'ah economic law. This research uses descriptive research method analysis with qualitative approach and literature for secondary and other data. The result of this study is that the land ownership transfer agreement that takes place in the Rahn contract is invalid, because basically the rahin only guarantees land as debt security and the transfer of land ownership has an element of imbalance between the value of debt and the value of land (marhun). In order for the Rahn transaction to be in accordance with the provisions of the Shari'a, the agreement in the repayment of the debt can be made provided that the rahin party may give the land (marhun) to the murtahin party as debt repayment, and but the murtahin party must increase the money from the remaining debt in the amount of the land priceKeywords: Pawn, Ownership, Transfer

Published: September 2024

Freelance work is increasingly popular in today's digital economy due to its flexibility and opportunities to work with various clients. However, freelance workers often face legal uncertainties, especially concerning termination of employment. This phenomenon is significant in Indonesia as freelancers do not always receive adequate legal protection compared to regular employees. This study examines the legal consequences of employment termination for freelance workers from the perspective of Islamic economic law. The research formulates issues related to the lack of legal protection, which leads to uncertainty for freelance workers in employment termination, and seeks solutions to enhance legal certainty and their protection. The research method used is the theoretical analysis based on studying labour law, Islamic economic law, and regulations related to freelancers in Indonesia. The findings indicate that freelance workers must have clear legal protection for service agreements, fair income rights, and adequate social security. Implementing principles of justice and balance from Islamic economic law is expected to improve these conditions. Thus, the study recommends developing more inclusive regulations to enhance legal certainty and welfare for freelance workers in Indonesia. The conclusion emphasizes the need for better legal protection for freelance workers, taking into account the principles of Islamic economic law, to provide better protection for their rights, reduce uncertainty, and enhance fairness in freelance employment relationships in Indonesia.Keywords: Freelance Workers; Islamic Economic Law; Legal Protection; Termination of Employment

The Study highlighted research engagement and productivity among academics in East Java, Indonesia’s private universities. It communicated three research inquiries: 1) How do 30 English Education Departments’ research productivity levels represent 288 Academics in East Java’s private universities? 2) To what extent do EFL academics’ participate in different research-related activities? 3) What drives the EFL academics’ interest in conducting research? Understanding these matters is critical for improving research production and personal performance. The Study utilized a Quantitative descriptive approach by analyzing evidence of overall productivity scores in the Sinta Database. In addition, an online survey was issued to point out academics’ involvement in research and the drives beneath their participation. The findings indicated that the research productivity among 30 English education departments was mainly low. Academics intensively engaged in writing, citing, conducting, and reading research. However, publishing research in recognized international journals indexed by Scopus or Web of Science, publishing in accredited national (Sinta Tiers one and two), and proposing intellectual property rights received less scrutiny. Their research drive was primarily for professional development, knowledge contribution, and self-awareness; research is a component of their job, alongside teaching and community services. However, promotions, governmental positions, and professional allowances were less motivating. The findings emphasize the significance of targeted funding and mentorship to facilitate publications, promote technical advancement, and stimulate the pursuit of intellectual property rights to enhance research productivity.

Czy i jak wdrażać nowoczesne technologie? Kontrowersje wokół unowocześniania narzędzi pomiaru na przykładzie neuropsychologii klinicznej
Authors: Łojek Emilia
Published: September 2024

W dobie ogromnego rozwoju nowoczesnych technologii w środowisku neuropsychologów toczy się dyskusja na temat modernizacji metod pomiaru diagnostycznego stosowanych w praktyce klinicznej. W odróżnieniu od obszaru badań naukowych praktykę kliniczną w neuropsychologii charakteryzuje duży opór przed modernizacją narzędzi pomiaru. Korzenie technik badania neuropsychologicznego powszechnie stosowanych w praktyce klinicznej nawet w krajach wysoko rozwiniętych sięgają XIX wieku. Istnieje wiele przyczyn tego zjawiska. Jedną z nich jest troska o zachowanie najwyższych standardów psychometrycznych i klinicznych ustalonych dla metod oraz procedur badania diagnostycznego, wypracowanych w toku rozwoju neuropsychologii jako nauki. Modernizacja i tworzenie nowych metod, które będą miały zastosowanie w praktyce klinicznej, może dokonywać się na wiele sposobów: a) w efekcie integracji neuronauk i nauk o zdrowiu, b) dzięki wdrażaniu nowoczesnych algorytmów psychometrycznych i matematycznych, w tym sztucznej inteligencji, oraz c) przez dane pozyskiwane przez urządzenia techniczne, z których korzysta pacjent w życiu codziennym. Każda z tych potencjalnych dróg rozwoju ma jednak swoje ograniczenia. Akceptując konieczność unowocześniania narzędzi służących diagnozie neuropsychologicznej w praktyce klinicznej, nie należy zapominać, że wdrażanie nowoczesnych technologii nie może być celem nadrzędnym. Dla dobra pacjenta niezbędne jest zachowanie wypracowanych na przestrzeni lat wysokich standardów psychometrycznych i klinicznych dla metod pomiaru.

How to Weaken the Endowment Effect in the Housing Market? The Role of Behavioral Interventions
Authors: Tomal Mateusz
Published: September 2024

The endowment effect is one of the key behavioral biases causing friction in the housing market. It results in sellers’ offer prices being inflated relative to buyers’ bid prices. Although this effect has been confirmed in many studies, little is known about how it can be reduced or eliminated. Therefore, this article assesses the impact of behavioral interventions on the intensity of the endowment effect using the Polish housing market as a case study. The research was based on a lab-in-the-field experiment, in which a hypothetical transaction in the secondary sales housing market was simulated and the recruited respondents were randomly divided into sellers and buyers. The endowment effect was measured by the gap between the average value of minimum prices for which sellers would be willing to sell a dwelling (WTA) and the average value of maximum prices that buyers would be willing to pay to acquire that dwelling (WTP). The results show that the endowment effect significantly decreases but does not disappear after the application of behavioral interventions. The latter consists of highlighting relevant information about the market price of a property and visualizing it graphically. Specifically, before the intervention, the WTA-WTP gap was 7.01%, and after 2.48%.

This research aims to evaluate the potential of green tea infusion in reducing Malondialdehyde (MDA) levels in the lungs of mice exposed to electronic cigarette vapor. The research employed an experimental method with a Randomized Post-Test Only Control Group design. The research sample consisted of 20 male mice aged 3-4 months with an average weight of 30 grams, divided into four groups: normal group (CN), negative control (NC), treatment 1 with a dosage of green tea 0.03 g (T1), and treatment 2 with a dosage of green tea 0.06 g (T2).
After the treatment, an analysis of MDA levels in the mice's lungs was conducted by TBARS test. The average levels of MDA in mice were obtained as follows: CN=12.669 µM, NC=23.940 µM, T1=10.997 µM, T2=14.395 µM. Statistical analysis using the One-Way ANOVA test revealed significant differences (p<0.05) between CN and NC, NC and T1, and NC and T2. These findings indicate that green tea infusion has the potential to reduce MDA levels in the lungs of mice exposed to electric cigarette vapor. Thus, this research provides a foundation for further studies regarding optimal dosage and the mechanism of action of green tea infusion in combating the negative effects of exposure to electronic cigarette vapor on respiratory organs.

Diseases are a constant of the human experience and have been affecting past populations of all periods, including those that practised cremation as a dominant burial rite. This paper focuses specifically on children’s health status in the Late Bronze and Iron Age (circa 1500–600 BC) inferred from the osteological analysis of cremated human remains. We have analysed skeletal material from four Croatian (Poljana Križevačka, Slatina, Batina and Sotin) and four Austrian (Franzhausen-Kokoron, Unterradlberg, Inzersdorf, St. Pölten) cemeteries to demonstrate that despite the fragmentation, distortion and selective recovery process of the funerary activities, cremated remains still yield important information on the life and death of children in later European prehistory. Children in the Croatian graveyards were more frequently affected from pathological lesions (38%) than children in the Austrian sample (3%). Cranial porosity, cribra orbitalia, and endocranial lesions dominated, probably related to metabolic diseases such as rickets and scurvy which were noticed primarily in children younger than six years at death. Differences between the Croatian and Austrian samples are likely associated with taphonomic processes as indicated by differences in bone weight and fragmentation size. Since children are the most vulnerable part of communities, a focus on children’s morbidity and mortality can elucidate the living conditions of prehistoric societies as a whole.
Saber de experiência feito de estudantes da Educação de Jovens e Adultos: conhecer para valorizar
Authors: Ferreira Daiane Ferreira , Pereira Elaine Corrêa
Published: September 2024

O artigo apresenta os resultados de uma pesquisa de doutoramento realizada no âmbito de uma Escola Municipal de Ensino Fundamental de Educação de Jovens e Adultos Paulo Freire (EMEJA). Nos diálogos trilhados com as professoras dessa escola andarilha, objetivamos investigar se a formação continuada contribuiu para a reflexão da prática dessas educadoras. O levantamento dos dados deu-se por meio de perguntas fechadas a partir de um questionário. Partindo das respostas, empregou-se a metodologia do Discurso do Sujeito Coletivo para a análise dos dados, gerando um Discurso Coletivizado (DC) denominado “Conhecimentos e experiências dos sujeitos: ensino e aprendizagens”. A partir das análises, observamos que as professoras possuem uma compreensão sobre a importância da valorização dos saberes socialmente construídos pelos estudantes; que os saberes prévios precisam estar incorporados ao fazer pedagógico, na condição de uma educação libertadora e não bancária; e, ainda é possível compreender que o olhar atento e cuidadoso também dialoga com a formação continuada, respeitando as especificidades da EJA.
An Integrated Method for Disease Risk Prediction Using Next-Generation Sequencing Data
Authors: Nhan Ta Van , Du Dang Trung , Minh Nguyen Thi Hong
Published: September 2024

Disease screening has seen increased adoption owing to heightened health awareness among individuals. Traditionally, wet labs have served as the conventional approach for testing; however, recent strides in bioinformatics have facilitated genetic testing and disease risk detection through computational analysis of data. This study presents a preprocessing methodology tailored for next-generation sequencing (NGS) data, integrating advanced computational tools. Leveraging the inherent advantages of NGS technology, this methodology ensures the acquisition of high-quality data essential for model training. Consequently, machine learning algorithms and neural networks are deployed to accurately predict disease risk and identify significant genetic variants. The performance of the proposed methods is higher than that of previous research. Through rigorous analysis, we have identified a subset of the most significant 8 SNPs linked to obesity and 61 SNPs associated with type 2 diabetes. These findings contribute to an understanding of the genetic factors underlying these complex diseases.
Synesthesia in Multimodal Perceptual Image as a Result of Conceptual Integration (descriptive register of the English literary text)
Authors: Kucher V. V.
Published: September 2024

The article presents a study of perceptual multimodality which implies simultaneous perception by visual, auditory, olfactory, tactile, and other perceptual modalities. In the literary text perceptual multimodality is conveyed through the means of the descriptive register of speech, which is aimed at emphasizing the perceptual semantic component of the situation. Perceptual multimodality manifests itself in synesthetic metaphor. The article scrutinizes synesthetic metaphor as a means of perceptual multimodality from the standpoint of conceptual integration theory. The article aims at analyzing the process of synesthetic metaphor formation with the help of conceptual integration modeling.

   The aim of the study presupposes the following: firstly, to analyze linguistic means creating a multimodal perceptual image representing the visual, auditory, olfactory, and tactile semantic components of the situation of perception; secondly, to consider the register relation to an utterance when modeling the processes of mental space integration; thirdly, to describe the lingual means representing a multimodal perceptual image by means of cognitive-stylistic analysis, taking into account specific features of the descriptive register of speech.

   The analysis of the input spaces’ domains makes it possible to identify the conceptual features that serve as the basis for the metaphorization resulting in blended space: the domain of the input space SMELL expressed by the lexeme pollen integrates the semantic features of visual and olfactory perception within the Blooming flowers frame. The domain “pollen” endows the adjacent mental spaces SOUND, COLOR with the conceptual attribute “the ability (of three-dimensional physical objects) to float in the air”. The article presents the models of conceptual metaphors that reveal the way the conceptual characteristics are gradually borrowed into adjacent mental spaces and a blended space is formed. The conceptual features of the integrated mental space are as follows: color is a substance (and not an inherent feature), sound is a visible substance; color and sound float in the air in waves, mixing like homogeneous substances.

   The study results in a model of multicomponent integration of mental spaces, which is reflected in the text by the author’s synesthetic metaphor.
Components of Creolized Texts and their Functions (A Case Study of American Movie Posters)
Authors: Jingyu He
Published: September 2024

The article studies the functions of verbal and non-verbal components of creolized texts, which combine multiple codes in one text. In other words, a creolized text is multimodal. This article discusses the main components and functions of the movie poster as a creolized or multimodal. The movie poster fulfils aesthetic and commercial functions as the main means of movie promotion, conveying information and giving the movie a certain value and meaning. From the point of view of semiotics, the movie poster consists of verbal and non-verbal signs, which interact with each other performing the following functions: attraction, informative, aesthetic, symbolic, explanatory, suggestive, and image-building functions.
Reflection of Ideas about the World View in Olonkho “The girl bogatyr Dzhyrybina Dzhyrylyatta”
Authors: Kuzmina A. A.
Published: September 2024

The article examines the possibility of transforming the mythologized linguistic units of the semiotic system reflected in the Olonkho text P. P. Yadrikhinsky-Bedieele “The Girl Hero Dzhyrybyna Dzhyrylyatta.” This text has preserved many lost elements of the culture of the Sakha people. Verbal and non-verbal symbols have been identified that reflect the traditional picture of the world. It has been found that the action code of Olonkho revolves around the main sacred action - the worship of aiyy deities. At the same time, a special place is occupied by sequential actions during the performance of the maternity rite, associated with the veneration of the patroness of childbirth – the goddess Aiyysyt. Clear spatial-structural loci of the Yakut pantheon of deities are given. The magical veneration of nature is represented by zoomorphic archetypal symbols. The landscapes of the upper, middle and lower world represent the structuring sound code in the Olonkho. Behavior in the middle world is regulated by the following key concepts: upper/lower, right/left, western/eastern, noble/ignoble, male/female, life/death. The tempo of Olonkho is set by the epic chronotope of “compressed” and social time. Collective preferences for color designations and numerical symbolism are strictly adhered to.
