The object of this study is the process of grinding and crumbling the surface layer of the soil with turf of winter crops by X-shaped working bodies. It has been established that the use of a grinding group based on X-shaped rotary working bodies as part of combined tillage tools makes it possible to preliminary loosen the surface layer of heavy soils (overdried or overmoistened). It was established that the optimal values of the parameters of the section of the X-shaped rotary working bodies for the quality of loosening the soil in a layer of 0–10 cm at a depth of cultivation of 14±2 cm depend on the speed of the unit. Thus, at a speed of movement of the unit of 2 m/s, the optimal value of the diameter of the rotor blade is 335.9 mm, the distance between the axes of the rotor batteries is 316.4 mm, and the distance between the rotor blades in the battery is 195.6 mm. At a unit movement speed of 2.5 m/s, the optimal values of these parameters are 331.2, 325.7, and 211.3 mm, respectively, and at a unit movement speed of 3 m/s – 330.1, 346.8, and 106.1 mm. It was also established that the stability of the movement of the X-shaped working bodies according to the root mean square deviation of the working depth increases with the increase in the speed of the unit. Thus, at a unit movement speed of 2.5 m/s, the root mean square deviation of the soil tillage depth is 1.21 cm, at a unit movement speed of 3 m/s – 1.07 cm, and at a unit movement speed of 3.5 m/s – 0 .63 cm. It was also established that the stability of the movement of the working bodies according to the depth of cultivation decreases with an increase in the speed of movement of the unit. Thus, at a movement speed of the unit of 2.5 m/s, the average soil tillage depth is set at the level of 13.1 cm, at a movement speed of the unit of 3 m/s – 12.6 cm, and at a movement speed of the unit of 3.5 m/s – at the level of 11.9 cm.

Published: September 2024

The object of research is the processes in hydraulic motors based on power cylinders, designed to drive the shaft of the working equipment in modern machines into rotational motion.
When using standard motors, a problem arises relating to the need to introduce additional devices into the structure of the mechanisms of modern machines. Such devices are aimed at matching the rotation frequency of the motor shaft with the rotation shaft of the working equipment of these machines. Such a device is a reducer, the use of which leads to the appearance of a number of disadvantages. Their elimination is achieved by using the results of this study.
The reported results differ from standard motors that are mass-produced, in that, based on research, motors with a rotation frequency of its shaft in the range from zero to two hundred and more revolutions per minute are proposed, which is not realized by known motors. This testifies to the construction of motors based on power cylinders, which make it possible to realize this range of rotation frequencies of its shaft.
The special and distinctive features of the results are based on the application of the principle of disintegration of motor elements into two functional components. One of them includes power cylinders with a crankshaft, and the second one includes the distribution system of the working fluid.
The motor implementation went through the stages of designing computer and physical models and devising schematic solutions. Calculation dependences were obtained to determine the main design parameters, according to which the motor was manufactured in the form of a full-scale sample.
The scope and conditions of practical use refer to machines with working equipment capable of functioning under a mode with a low rotation frequency and a significant torque on the motor shaft

Published: September 2024

The object of this study was the weld material of a new Ti-6.1Al-6.0Zr-6.3Sn-3.2Mo-1.1Nb-1.2Si alloy, which was obtained by electron beam welding.
Electron beam welding (EBW) provides rapid melting and cooling with crystallization under significant temperature gradients. For the pseudo α-titanium alloy, this leads to the appearance of significant residual stresses in the joint and determines the specificity of the dispersion decay of the β-phase. Residual stresses are reduced by preliminary heating, removed by heat treatment. Such processing exerts a critical influence on the formation of the structure and phase composition of the weld and the zone of thermal influence of the electron beam; it can form macro defects, undesirable phases, and structural states.
The conditions of heat treatment have been determined to bring the welded joint from complex alloyed pseudo α-titanium alloy to the required level of mechanical characteristics. The structure, phase morphology, elemental composition, and mechanical characteristics of welded joints without additional heat treatment have been compared, with preliminary local heating of 400 °C, with additional post-weld local annealing at ТТ=750 °С, tT=4 minutes and sequential annealing in the furnace at ТТ=850 °C, tT=60 minutes. It has been established that a full cycle of heat treatment of a welded joint provides the highest characteristics of strength and plasticity, but local heat treatment also makes it possible to obtain a defect-free joint with satisfactory characteristics for less responsible products. It is shown how heat treatment of pseudo α-titanium alloy makes it possible to get rid of unwanted phase formations (Zr,Ti)5Si3Al and transform them into (Zr,Ti,Nb,Mo)3SiAl.

Published: September 2024

The object of the study is epidemiological grouping using the SEIR mathematical model on a machine learning-based multilayer network. The problems in this research are related to managing epidemiological data on a large scale to determine disease patterns and identification such as the number of recovered cases, number of infected cases and number of deaths and demographic factors. In the process, traditional methods make it difficult to carry out processes such as determining patterns and identifying diseases. So, it is necessary to use machine learning and the SEIR (Susceptible-Exposed-Infectious-Recovered) mathematical model which can be integrated with multilayer networks to increase accuracy and effectiveness in identifying diseases and determining patterns. The results obtained from this research are a model that can identify and determine patterns of disease spread in large-scale epidemiological data. In its application, the SEIR mathematical model combined into a social layer and an environmental layer in a multilayer network. This research is research with a level of novelty in the application of the SEIR mathematical model to multilayer networks and machine learning so that the model formed can be used to view the distribution of epidemiological data for disease-related information. Machine learning aims to process large-scale data in minimal time resulting in clustering and identification of diseases such as flu, Covid-19 and pneumonia. This research has an accuracy of 94 % using the MAPE evaluation technique. It is hoped that the resulting model can be used in the world of health for disease mapping in certain areas as a reference for mitigating the spread of disease

French Chambers of Commerce and Industry as Participants in Local Collaborative Governance and Collaborative Management
Authors:   Adam Mickiewicz University in Poznań (Poland), Walkowiak Katarzyna
Published: September 2024

Local governance continues to be one of the key concepts in the contemporary approach to the functioning of local government, administration, and public management. The most crucial premise of this concept is the interactive way of exercising power, where various actors identify and implement joint projects, including residents, community organizations, and public and private institutions. Despite significant interest in this concept, it needs further analysis and refinement. In academia, the lack of conceptual clarity makes it difficult to analyze and identify the differences in collaborative governance and management processes. In practice, the concept’s full potential is not recognized, which hinders its application in local decision-making. An attempt has been made to fill this research gap by analyzing the role of French chambers of commerce and industry as participants in local collaborative governance and collaborative management. Chambers of commerce and industry have a long tradition and are a permanent element of the French political system. Their current status is the outcome of a long historical process and institutional development closely linked to France’s significant political and economic changes. Through literature and data analysis, as well as the study of documents, selected aspects of the activity of chambers of commerce and industry in local collaborative governance and collaborative management are presented, as well as identifying the challenges faced by these institutions in the process of collaboration with local authorities and other stakeholders.

This study conducted a comprehensive and thorough evaluation of budget expenditures on agriculture in Poland from 2004 to 2022 through the prism of fiscal policy functions (i.e., allocative, redistributive, and stabilizing functions). The volume, fundamental dynamics and structure of the budget expenditures on agriculture were meticulously analyzed, as were the impacts of those expenditures on the implementation of key objectives of agricultural policy—that is, objectives related to the level and stability of farm income and the dynamics of investment in agriculture. It was determined that redistributive expenditures dominated the structure of budget expenditures on agriculture during the post-accession period. By contrast, the shares of allocative and stabilization expenditures fluctuated widely. Moreover, agricultural budget expenditures had a positive effect on reducing the income disparity of farmers relative to other socioeconomic groups. However, the redistributive effect of budget expenditures was only strong during the initial few years after Poland acceded to the European Union. The findings of this study revealed that agricultural budget expenditures have a positive effect on the stabilization of agricultural income and the investment activity of farmers, thereby supporting development processes in agriculture.

Based on the assessment of contemporary reality, it can be said that one of the most critical functions of a modern state is to provide its citizens with an acceptable level of security – that is to say, to create optimal conditions for protection against hypothetical and real threats, such as potential natural disasters, consequences of civilizational advancements (accidents or man-made disasters), terrorist attacks, wars, and armed conflicts. It should be emphasized that in modern, democratic societies, the right of people (social groups) to be protected from numerous threats results from the legal, ethical, and moral norms in force, which have been developed in civilizational development and are based on historical experience. The research focused on analyzing normative documents (laws and regulations) and selected scientific and popular science literature dedicated to the functioning of the crisis management system and contemporary management. The synthetic conclusions of this analysis constitute the basis for further in-depth research.
Consuming Bodies: Ticks, Pigs, and Gothic Capitalism
Authors: Tirrell Jeremy Walter
Published: September 2024

A tick-borne illness has spread throughout the eastern United States, causing victims to develop a spontaneous allergic reaction to eating red meat. This condition’s etiology intersects with notable recent cases of porcine xenotransplantation: the insertion of organs from genetically altered pigs into human hosts. The antagonist in these scenarios is the sugar alpha-gal, which is naturally present in most mammals although not humans. This article draws from Bruno Latour’s depiction of modernity as an engine that produces contradictory hybrids to examine the capitalist ethic impelling cultural engagements with alpha-gal, in which the bodies of pigs and humans are cyclically conflated and differentiated as medical and edible commodities—both forms of sustenance. The consumption of these resources has a Gothic cast, which provides insight into their strange appeal, affect, and implications. This kind of quotidian Gothic invisibly pervades contemporary life, becoming palpable only through novelty, as transient examples emerge and dissipate while eliciting little sustained consternation.

Published: September 2024

Under conditions of complex geological structure and substantial share of hard-to-recover oil reserves, reservoir simulation is a key tool in reservoir management. Direct problems solved by reservoir simulation include forecasting of the production performance, control and management of reservoir development, and localization of residual oil reserves. Inverse problem solution is useful for updating the knowledge of geological structure, reservoir quality, and historical production data by means of history matching. The quality of history matching is fundamental to ensure reliable future forecasts and localization of residual oil zones. The main approaches to appropriate history matching rely on analysis and adjustment of well logging and geological parameters, as well as checking and correction of errors, inadequate historical data, application of physics-based and reasonable approaches and tools. The prerequisite for adequate history matching and predictive ability of the resultant reservoir simulation model is the compliance of simulated and actual energy state of the reservoir. In this paper, the initial stage of reservoir simulation is performed, the approach to history matching of reservoir energy state aimed at improving the quality of further predictions is described as exemplified by one of the production areas of Russian oil field. The main causes of poor history match of formation and bottomhole pressures are revealed. These causes are grouped as follows: — geological causes/reservoir quality, which include permeability field distribution, reservoir connectivity, and determination of rock and fluid compressibility;— technical causes (during reservoir simulation), that is model limitations in case of larger areas, the need to use sector models, consideration of buffer region;— technological causes, including inadequate historical data or lack of data, detection of behind-the-casing flows and production casing leaks in wellbore, etc. For each group of factors that have a substantial impact on reservoir pressure, recommendations and methods of energy state history matching on geological and reservoir simulation models are provided, examples are given.
VELOCITY AND EVOLUTION OF SHOCK WAVES IN SAND WITH INCREASING WATER CONTENT
Authors: Gizatullin R.F. , Muhametzyanov A.F.
Published: September 2024

Interest in the problems of shock wave propagation in saturated porous media is associated with studying seismic exploration issues, modeling the hummer effect during hydraulic fracturing, studying the water-gas impact on formations for the purpose of efficient oil production, etc. Experimental work on waves in bulk media is usually carried out in shock tubes. Traditionally, shock tubes are used to study the characteristics of the propagation of shock waves in various media, to analyze the wave properties of these media based on the speed of the shock waves and the change in the shape of the pulse along the passage of the first – main pulse. In a shock tube equipped with a section of bulk media, the wave is repeatedly reflected from the surface of the porous medium under study and the upper end of the tube. Re-reflected waves can be used to study changes in the environment that occurred under the influence of a shock wave, i.e. as probing pulses. In this article, sounding is understood as identifying acoustic properties (changing the shape of shock pulse diagrams and their velocities). This paper presents the results of experimental studies of the propagation of shock waves of small amplitude in sand with a volumetric content of liquid in the pore space from 0 to 40 %, and illustrates the influence of the presence of liquid in the pores on the shape of the main and probing pulses. The research was carried out using the Shock Tube installation, in the Laboratory of Experimental Hydrodynamics of the Mavlyutov Institute of Mechanics of Ufa Branch RAS. An increase in the speed of wave propagation was established with increasing water saturation of sand in the range from 0 to 40 %. An increase in the amplitude of reflected waves when passing through sand, the formation of peaks and stretching of pulses were discovered. The research results can be used in processing geophysical data to interpret seismograms of sandy deposits saturated with gas-liquid systems.
Analysis of the effect of mismatch on nonlinearity in hybrid RC-DAC

This paper is dedicated to the analysis of the effect of elements mismatch on the nonlinearity of N-bit hybrid segmented RC-digital-to-analog converter. In the structure of the hybrid digital-to-analog converter under consideration, a binary capacitive segment processes the most significant bits, whereas a unary resistive segment processes the least significant bits. Since the consi¬dered digital-to-analog converter is heterogenous, the elements of both segments differ by the type (resistors or capacitors) and area. This causes an optimal ratio of segments resolutions to shift in respect to the total DAC area minimization. Therefore, the goal of the current research is to obtain an expression for optimal segments resolutions in dependance on the ratio of unit capacitor and resistor areas. For this purpose, a parametric mathematical model of the considered converter has been developed in MATLAB. The elements arrays of both segments are influenced by random errors. The simulation of differential and integral nonlinearities has been carried out, which demonstrated a lower contribution of the resistive segment on nonlinearity, in contrast to the capacitive one. Besides, the increment of a capacitive segment resolution improves the yield of both nonlinearities.
Gobernanza del agua: humedal Jaboque. PILEO-PRAE del Colegio Charry, Institución Educativa Distrital
Authors: Afanador-Castañeda Héctor Alexander
Published: September 2024

Es pertinente informar que el artículo de investigación emerge de la sistematización e interpretación de resultados del proyecto ambiental educativo del Colegio Charry, que tiene como propósito la formulación de explicaciones sobre el humedal Jaboque desde una visión de comprensión humana. El diseño metodológico asume el paradigma interpretativo con la intención de resignificar las formulaciones explicativas elaboradas por los estudiantes de grado noveno. Para ello, se elabora una secuencia de actividades a través de un recurso educativo digital, el cual desarrolla el procesamiento de información especializada y publica sobre el contenido biológico-ecológico y ambiental del humedal Jaboque. Este humedal de la localidad de Engativá es un cuerpo de agua adyacente al barrio Garces Navas, donde se encuentra el colegio, y pertenece a la red de protección hídrica de la Secretaría Ambiental de Bogotá.La interpretación de los datos tiene en cuenta el análisis del contenido para determinar la red de conceptos relacionados en las explicaciones y los aspectos estructurantes de biopoder relacionados con la gobernanza del agua. En cuanto a los resultados, se establece que las formulaciones explicativas incorporan nuevos conceptos a medida que interactúan con la nueva información; asimismo, el conjunto de explicaciones da cuenta de relaciones de dominación asociadas a la autoconservación frente al humedal Jaboque. Por último, se concluye que la objetivación de las explicaciones complementa y amplía la comprensión subjetivada de la realidad observada por parte de los estudiantes sobre el humedal. Asimismo, el desarrollo de la comprensión depende de la acción relacional entre el conocimiento ontológico y el conocimiento epistémico, propio del sujeto y de la interacción con los demás.

BACKGROUND: The posterior-superior insula (PSI) has emerged as a potential target for non-invasive brain stimulation (NIBS) in the treatment of peripheral neuropathic pain. However, current methods for identifying the PSI require expensive and time-consuming brain imaging and neuronavigation. Here, we propose the Fast-PSI method, a novel approach based on craniometry and intracranial Euclidean distances proportions comparisons between scalp landmarks, to swiftly and accurately locate the PSI projection on the scalp. METHODS: Eleven healthy participants underwent identification of the PSI and cranial landmarks (CL) MNI152 coordinates using neuronavigation. Euclidean distances between nasion and PSI (N-sPSI), nasion and inion (N-I), vertex and PSI (Cz-sPSI), and vertex and tragus (Cz-T) were calculated. Craniometric-based Euclidean distances between PSI and CL were also measured. Correction factors were developed based on the proportionality of distances. RESULTS: Mean distances’ proportions were consistent between stereotactic-based and craniometric-based measurements. Correction factors were determined as 0.67 for N-sPSI and 0.75 for Cz-sPSI. The Fast-PSI formula was established using these factors to swiftly locate the PSI projection on the scalp. Test-retest, intra- and inter-rater reliability coefficients were high, with no statistical difference compared to neuronavigated coordinates. The mean time for Fast-PSI determination was significantly shorter than traditional neuronavigation. CONCLUSION: The Fast-PSI method demonstrates high precision and reliability in identifying the PSI projection for NIBS in neuropathic pain treatment. Its rapid execution and accuracy make it a promising alternative to current techniques, potentially reducing time and resource burdens associated with neuronavigation. Further validation in clinical trials and everyday practice is warranted to assess its utility in clinical settings.
Recruiting the ‘Selfish Gene’: The Threat to the Sacred and the Self-Suspicion
Authors:   Institute for Philosophy and Social Theory (IFDT), University of Belgrade, Serbia, Shevchenko Sergei
Published: September 2024

The experiment of Chinese scientist He Jiankui in editing the genome of twin girls has generated a new wave of suspicions about biotechnology. In fact, staff biotech labs and influential international figures were under suspicion, because they considered to use our desire to become healthier, stronger, and more efficient for the sake of transforming the world’s population. In their social significance, these concerns go far beyond the wish to reduce the uncertainties associated with the development of new technologies. The image of the threat posed by genome editing has paved the way for the “liquid fear” of displacement and substitution described by the sociologist Zigmunt Bauman. It also overlapped with the immunopolitical anxiety associated with the fear of being infected and losing one’s identity. At the same time, the suspicion of genome-editing technology clearly mirrors the motives of the violated sacred described by Emile Durkheim, Mary Douglas and contemporary cultural sociologists. However, in the case under consideration, these motifs take on a very special meaning. The human genome, which determines how we should live, and therefore has sacred characteristics, is under threat of violation. At the same time, our life, too, turns out to be only part of the evolutionary competition of “selfish genes” striving to spread in space and time. Usually, the danger associated with the sacred lies either in its desecration or in desire to gain its support. We can interpret the suspicion of genome editing as an attempt to form a prescription for the sacred game of “selfish genes,” to recode its internal principles. And since the sacred in this case is contained in every cell of the human body, the object of suspicion is the suspect himself.
Accelerated Reflexivity — Depressed Sociality
Authors:   nstitute of Philosophy, Russian Academy of Sciences (RAS), Moscow, Russia, Afanasov Nikolai
Published: September 2024

The article concerns the problem of distinguishing the key features that qualitatively define Modernity. Against the background of transition from industrial to postindustrial capitalism the original projective character of social thought changes. In the society of “late modernity” to the fore come not the critical projects of reconstruction or modernization but social and cultural reflection, that aims to help in local orientation in the increasingly complex world. Large-scale social thought narratives and research programs buckle under the onslaught of original authors’ approaches. As the result we face the fragmentation of theoretical social philosophy field and social frustration. The article aims to detect the common ground, on which the further theoretical discussion about the disciplinary boundaries and the subject of social theory can be developed. The author leans on the attempts made in the last few decades of the 20th century (Jürgen Habermas, Hermann Lübbe, Ulrich Beck, Anthony Giddens, Scott Lash) to provide a common framework of productive understanding of contradictions and tendencies of Modernity. To these instrumental but simultaneously concrete ideas belong social acceleration and reflexivity of modernity. The acceleration of historical eventfulness led to a symmetrical response — it begins to see its task in keeping in pace with gained speed. This interpretative acceleration generates a situation of depressed sociality, when all the attempts to critically comprehend what is happening only increase the frustration. In the conclusion the author assumes that social acceleration understood exactly in the sense of reflexivity could be a turning point for redefining philosophical coordinates of the theory of Modernity.
The Epistemological Usefulness of Artistic Residencies and the Husk of Repetition
Authors:   Association of Artist-in-residence Programs, Kolomna, Russia, Chaika Zhenya
Published: September 2024

In the article, artist residencies are considered as an object of research. The stereotypes associated with the role of artist residency in the artistic process are examined: for example, the idea of site-specificity and of the artist in residency as a person necessarily endowed with fresh optics and destined to make the place her own. The article notes that in the world of artist residencies, the mode of work for the result, or the creation of a work, and the mode of research are separated. Currently, there is a tilt towards research residencies. Further, the article discusses the specifics of artistic research and its role in the artistic process. Jean-François Lyotard’s approach to exhibitions as philosophical statements is mentioned and Nelson Goodman’s concept of the creation of worlds is analyzed. Strategies of work in the artist residency are described through specific ways of creating worlds, research in the residency is analyzed as an opportunity to construct a correct, that is, epistemologically productive version of the world. Through the expansion of some points of Goodman’s analytical aesthetics, the emphasis is placed on artist residency as a unique, laboratory, space/condition/ context for the creation of new symbolic systems — worlds — through the presentation of referential chains in their formation and deciphering. In the situation of artist residency, new worlds are being created literally before our eyes, and, taken as a subject of research, artist residencies provide conditions for the decomposition of the artistic process into its components. Artist residencies are spaces where connections between worlds unfold.
Between River Low and Mountain High. Artistic Research and What Characterizes It
Authors:   Garage Academy, Moscow, Russia, Shirokostup Olga
Published: September 2024

This article presents an overview of the origin of the concept of “artistic research” and the discussions around it that unfolded in the artistic and academic environment. Artistic research emerged within the framework of the academy, but at the same time, as many critics emphasize with whom the author of the article agrees, it should not be colonized by it. The article examines the models of conducting artistic research with reference to the Mika Hannula’s, Juha Suoranta’s and Tere Vadén’s Artistic Research Methodology and identifies general patterns that characterize this practice in all its diversity. The basic formula presents artistic research as an artistic process to which contextual, interpretative and conceptual work is added, aimed at argumentation of a point of view. In any case the practices of artistic research are supposed to be performative. The author of the article offers a look at the course of artistic research as a process extended over time, including alternating phases and various “points of visibility”. Artistic research can be presented in the institutional space if it coincides with the program and objectives of a particular institution, but at the same time it can be carried out independently. The finished project demonstrated within the framework of the institution may be preceded by a long research period remaining “behind the scenes”, or some intermediate research results may be presented in a variety of formats.

This protocol describes the automated extraction of HMW DNA from nucleated blood samples intended for long-read sequencing using the Nanobind® tissue kit and the Thermo Fisher KingFisher™ Apex. It follows the "Nanobind® HMW DNA Extraction from 5 μL nucleated red blood cell on KingFisher Apex" R&D protocol, which was developed by Pacific Biosciences and validated by the Tree of Life Core Laboratory using bird, fish and reptile nucleated blood samples. This process is effective for any species with nucleated blood within the chordate group, covered by the Tree of Life Programme, however difficulties can arise with samples where preservation has not been optimal. In addition to allowing a higher throughput of nucleated blood samples, this protocol is also particularly beneficial for nucleated blood samples where clumping has occurred, with higher yields obtained compared to processing them using the Manual Nucleated Blood Nanobind® protocol. The output of this protocol is HMW DNA of high quality and quantity, which can be directed towards the HMW DNA Fragmentation: Diagenode Megaruptor®3 for LI PacBio protocol.

COMPUTER VISION TO SUPPORT PRE-SERVICE TEACHER MASTERY OF STUDENT CENTRE APPROACH
Authors: Hikmawan Rizki
Published: September 2024

Various researcher state that to ensure student had the 4Cs competence is to use student-centered approach in the classroom. This further recognize the skills to create dynamic classroom as the core-skills of 21st teacher. To create such classroom, a teacher must be able to master the systematic and dynamic aspects of learning. It requires teacher to fully aware of every student activity. However, based on preliminary investigation, there two things that become obstacles, namely: (1) teacher had hard time giving full attention to whole classes due to non-coercion manner of student-centre approach, and (2) mastery of dynamic aspects in learning requires real experience which will certainly spend a lot of time. They need practical solutions that can help them master the core skill of 21st teacher. Therefore, we designed an application with image processing features (face detection, face recognition, and pose extraction) in order to help teachers to give full attention and provide positive reinforcement for every classroom participant. The research is done by RD Method, whereas application design uses SDLC method.

Short-form videos have surged in popularity on social media platforms, captivating users with engaging content in brief durations. However, their impact on attention span can pose challenges such as frustration and reduced concentration on longer tasks. The aim of this study is to investigate the impacts of short-form videos on the attention span and study habits of students enrolled in the College of Vocational School Studies IPB University and to suggest effective strategies for mitigating the negative effects. Through questionnaires and interviews, the research explores TikTok video consumption frequency, perceived consequences of accessing abundant information effortlessly, and influence on academic learning. The study discovered that participants spent approximately 1-2 hours each day watching short-form videos and acknowledged their consequences. They reported feeling less concentrated in their study habits and recognized a correlation between watching short-form videos, attention span, and study habits.

Aim. To present a clinical case of osteomalacia associated with fibroblast growth factor-23-secreting tumor under the mask of ankylosing spondylitis (AS).

Materials and methods. Clinical observation of a 31-year-old patient with long-time diagnosis of AS is presented. Underestimation of back pain cause at the initial stage of diseaseled to an erroneous diagnosis of AS. A thorough assessment of the anamnesis, additional examination using modern imaging methods in combination with laboratory analysis (low blood phosphorus level, hyperphosphaturia, normal value of C-reactive protein, erythrocyte sedimentation rate, negative HLA-B27), made it possible to establish the correct diagnosis of “mesenchymal phosphaturic tumor of the left foot (surgical intervention dated 11.26.2020), secondary hypophosphatemic tumor-induced osteomalacia complicated by multiple bone fractures”, to carry out timely treatment with full recovery.

Results. The literature data on epidemiology, pathogenetic mechanisms, clinical manifestations and management approaches of tumor induced phosphopenic osteomalacia are presented. An algorithm for examining patients with suspected of this disease is described, taking into account the expression of somatostatin transmembrane receptors on the surface of a mesenchymal phosphaturic tumor.

Conclusion. One of the rarest causes of specific back pain is osteomalacia, which can be caused by various diseases, for example, a tumor secreting FGF23 The complexity of the diagnosis lies in the non-specificity of clinical manifestations – generalized myalgia and myopathy, ossalgia, pathological fractures, etc. Timely diagnosis and radical treatment makes it possible to achieve stable remission with complete leveling of symptoms, therefore surgical excision of the tumor is the “gold” standard of therapy.

In today’s digital era, learning apps have become increasingly important as they can change access to education and optimize learning processes. When developing a product for Mittweida University of Applied Sciences, the intention was to design an app that can be used in a supportive way in the university teaching of the Faculty of Social Work to improve the understanding of the learning material. This paper aims to find out whether learning motivation can be increased when a digital learning app is used in group work within a competitive environment. The digital learning app developed serves to create a space in which several students work together on the topic complexes through exchange or answer questions and motivate each other. To validate the increase in motivation, an evaluation was conducted with a group of students (n = 17) in which group work was simulated with the app. To create the competitive environment, the scores of the groups were openly compared. In addition, the best group received a prize. To determine motivation, questionnaires were used before and after the simulation. The questionnaires consist of a combination of the existing questionnaires on motivation FAM, MSLQ, and CMELAC. They are rated on a five- or seven-point Likert scale. The evaluation of the questionnaires shows that motivation cannot be increased in the simulation. Overall, no major change in motivation can be detected through the evaluation. In addition, the reward was not perceived as necessary. Thus, the question arose why no changes in motivation could be recorded via the snapshot. This may be due to various factors, such as the size of the period under consideration or the number of respondents. The evaluation also makes it clear that the main aspect of the app is not necessarily the motivation of the students.

Project-Based Learning (PBL) is a teaching approach that has been shown to enhance students’ learning in higher education. PBL ensures that students develop critical thinking and professional competence in civil engineering education through a well-rounded approach. In civil engineering modules, design projects provide practical design experience to the students. This allows them to apply their knowledge and skills across disciplines. The design of such projects plays a crucial role in their learning journey. Therefore, it is essential to ensure that they are well-designed. This paper presents a framework for designing PBL in a civil engineering module in a joint degree programme in Singapore. This framework for the PBL design is based on the Universal Design for Learning (UDL). A questionnaire was prepared to obtain feedback from students on their PBL experience. Through the implementation of PBL in Foundation Engineering, the students have feedback that the PBL was well-designed and had a positive impact on their learning.
