The narrative inquiry of a science teacher’s experience of developing physics experiments: from a mere conveyer to a dynamic collaborator
Authors: Kim Hee Ra , Kim Jung Bog , Yun Soyoung , Lim Sungman
Published: July 2024

This research aims to study a science teacher’s experience in developing physics experiments through narrative inquiry. The participant is a Korean secondary school science teacher who was in graduate school as a student studying gifted education. The data was collected over approximately 9 months. Collected data include observation of the participant’s module participation, in-depth and periodic interviews, and the participant’s assignments. The research outcomes are as follows. Firstly, the atmosphere of the modules was permissive and harmonious. As one of the student-teachers, she could ask and discuss freely. Secondly, she could develop physics experiments from her ‘own curiosity’. This might influence her position to change from rather passive to active. Thirdly, she could be able to achieve scientific inquiry as a student and a teacher. Fourthly, through hands-on activities, by applying researcher’, student’s, and teacher’s point of view, her profession as a science teacher has been strengthened. Lastly, Teacher A’s experience appeared meaningful in terms of enhancing teacher efficacy. The experience of developing the physics experiment became a turning point for her from a mere information conveyor to a dynamic collaborator.
Consultation Response: Spanish Draft Law for the Protection of Minors in Digital Environments (June 2024)
Authors: Xiao Leon Y.
Published: July 2024

This is a response to the consultation on the draft law for the protection of minors in digital environments. A representative of the Dirección General de Ordenación del Juego (DGOJ) has confirmed to me on 18 June 2024 by email that the draft Article 5 will indeed only regulate Embedded-Embedded loot boxes. I therefore raise two concerns. Firstly, Embedded-Isolated loot boxes should also be subject to stricter regulation because they are no less harmful than Embedded-Embedded loot boxes. Secondly, the Government must not mislead the public by giving the incorrect impression that Embedded-Isolated loot boxes will also be regulated by the draft law if it passes and/or that the draft law can address the entirety of the loot box problem.
Beyond independent latent classes: Testing the limits of human flexibility
Authors: Verbeke Pieter , De Walsche Maurice , Maelfait Pauline , Verguts Tom
Published: July 2024

A hallmark of human intelligence is the ability to flexibly adapt to novel situations. This flexibility relies crucially on the appropriate generalization of previously acquired knowledge. One influential theoretical framework argues that humans organize their knowledge in a collection of latent classes. Humans could then assign any novel situation to one of the latent classes (or construct a new one if it is too dissimilar), and thus generalize based on older knowledge. However, this framework is not sufficiently flexible to explain human generalization. In particular, we argue that at least three important features are missing: dependency, compositionality, and tuning. To empirically test this, we developed a novel behavioral task, which required adapting knowledge across tasks in order to generalize appropriately in the test phase. Across three experiments, dependency, compositionality, and tuning requirements were increasingly added to the basic task. Results demonstrate that humans are sensitive to all three types of structure. We discuss how current models must be extended to capture human generalization.

Published: July 2024

With the surge in global demand for seafood, although efforts are being made to guide fisheries and farmed aquaculture, which still rely on natural resources, toward sustainability, it is pertinent to guide people toward sustainable consumption patterns. We consider bluefin tuna, whose largest consumer is Japan and whose stock levels were at risk in the early 2010s, and examine whether consumers can be impelled to consume fish produced in a resource-conserving manner if they have adequate information on stock status and fishing methods. We explore the potential of fixed shore net fisheries and full-cycle aquaculture techniques, which have received limited attention in previous studies. Furthermore, we analyzed the effectiveness of ecolabels indicating that, in the case of natural products, no juvenile fish were caught, and in the case of farmed fish, no juveniles were used as seedlings or artificial seedlings were used. We conducted randomized controlled trial to analyze how information provision changes the marginal willingness to pay for fish commodity attributes. The analysis reveals that the information provision significantly and positively affects payments for bluefin tuna produced by resource-conserving fixed shore net fisheries and full-cycle aquaculture. Moreover, it significantly increases the premium for ecolabeling, suggesting the need to provide consumers with knowledge on resource status and fishing methods. However, as the effects of information provision are heterogeneous, new approaches such as consumer segmentation at the retail level are required to implement these efforts in society.
Perceived risk-utility tradeoffs of medical technology: A visual mapping
Authors: Brauner Philipp , Offermann Julia
Published: July 2024

The social acceptance of medical technology is crucial for the sustainability and effectiveness of healthcare systems, particularly in the context of demographic changes. Unlike most studies that focus on individual technologies, we measure the public perception across a range of medical technologies in a comprehensive study. We conducted an online survey with 193 participants from Germany and Bulgaria to assess perceived risk, utility, and overall attitudes (valence) toward 20 distinct medical technologies. This article presents a visual mapping of these technologies and investigates the individual and technology-related factors shaping these evaluations. Our findings suggest that perceived utility is the strongest predictor of overall attitude toward medical technology (β=0.886), with perceived risk playing a significant, albeit much smaller, role (β=-0.133). Together, these factors explain a substantial portion of the variance in overall attitudes (R^2=.959). Additionally, we found that individual differences, such as prior care experience and trust in physicians, significantly influence these perceptions. The article concludes with recommendations for effectively communicating the benefits and risks of medical technologies to the public, thereby enhancing their social acceptance and integration into healthcare systems.
Epistemic uncertainty: How preprints can reconfigure organizational theorizing
Authors: Heimstädt Maximilian , Dobusch Leonhard
Published: July 2024

Due to the structural transformation of the scientific public sphere, organizational researchers now frequently come into contact with preprints—scholarly texts that are intended for peer review but have not yet been submitted for or completed this evaluation process. Although reflexive organizational research has long been interested in the relationships between scholarly media and practices of theorizing, preprints have thus far been dismissed as a media genre that is not relevant for these activities. We challenge this view by showing that preprints can be highly relevant for theorizing because they possess the unique property of epistemic uncertainty. When researchers encounter a preprint, they cannot infer from the media genre itself whether or not their peers would consider the content of this specific preprint to be a legitimate contribution to theoretical debates. Using three core activities of organizational researchers—conceptualizing, grant writing, and reviewing—as illustrative examples, we show that how preprints reconfigure these practices of theorizing depends on whether researchers consider epistemic uncertainty as a threat or a resource. Thus, being sensitive to the generative potential of incomplete scholarly media contributes to our understanding of how theorizing changes in digitally networked environments. Finally, we discuss new challenges for organizational researchers when their preprints are encountered not only by their peers but also by audiences outside of academia.

Exploring the Access to the Static Array Elements via Indices and via Pointers — the Introductory C++ Case Expanded
Authors: Logožar Robert , Mikac Matija , Radošević Danijel
Published: July 2024

We revisit the old but formally still unresolved debate on the time efficiency of accessing the elements of 1D arrays via indices versus accessing them via pointers. To analyze that, we have programmed benchmarks of minimal complexity in the C++ language and inspected the machine code of their compilation in the x86 assembly language. Before exploring the performance, we briefly compared a few methods used for the execution time measurements. The results on the Wintel platform show no significant advantage in using pointers over indices except for some benchmarks and array (data) types. In other cases, the exact opposite may be true. The cause of this inconsistency lies in the compilation of the source code into the rather nonorthogonal x86 instruction set. Furthermore, the execution speed does not clearly relate to the instruction length. The parallel aim of this work is to provide a ground for further analysis and measurements of this kind using different compilers, languages, and computer platforms.
Physical Internet Enabled Traceability Systems for
Sustainable Supply Chain Management
Authors: Nachet Bakhta , Frendi Mohammed , Adla Abdelkader
Published: July 2024

Current supply chain management (SCM) requires the control of physical and information flows in order to satisfy the customer, i.e. deliver the right product to the customer at the right place, at the right time, at the right price and at the lowest cost. SCM is inseparable from traceability which makes reliable the said flows, accelerates the transmission of information on these flows, allows to access a detailed knowledge of the movements, and makes the flows visible. In order to streamline and monitor, if possible, in real time and permanently these logistical processes, we propose the design and implementation of an Ontology-based traceability system based on an architectural model for the physical Internet using computing resources such as Cloud computing, Fog computing and Internet of Things (IoT) to achieve efficiency and sustainability goals. To evaluate our system, we were able to carry out all the queries that the user can express whether he is a customer, a supplier or a manager.

Published: July 2024

Globally, cardiovascular diseases stand as the primary cause of mortality. In response to the imperative to enhance operational efficiency and reduce expenses, healthcare organizations are currently undergoing a transformation. The incorporation of analytics into their IT strategy is vital for the successful execution of this transition. The approach involves consolidating data from various sources into a data lake, which is then leveraged with analytical models to revolutionize predictive analytics. The deployment of IoT-based predictive systems is aimed at diminishing mortality rates, particularly in the domain of coronary heart disease prognosis. However, the abundant and diverse nature of data across various disciplines poses significant challenges in terms of data analysis, extraction, management, and configuration within these large-scale data technologies and tools. In this context, a multi-level fuzzy rule generation approach is put forward to identify the characteristics necessary for heart disease prediction. These features are subsequently trained using an optimized recurrent neural network. Medical professionals assess and categorize the features into labeled classes based on the perceived risk. This categorization allows for early diagnosis and prompt treatment. In comparison to conventional systems, the proposed method demonstrates superior performance.

Authors: Sokolovskyi Vladyslav , Zharikov Eduard , Telenyk Sergii
Published: July 2024

The basis for ensuring the safe operation of hydraulic structures is facility monitoring systems. The introduction of software tools for diagnostic modelling of filtration flows into the software of such systems is an objective step caused by recent real-life events. The aim of this study is to improve the accuracy of existing methods for numerical modelling of two-dimensional stationary filtration flows using the mesh method in the software of the facility monitoring system. The methods used in the study included the mesh method, the finite difference method, as well as approximation methods and numerical algorithms. As a result of the study, it was found that the proposed method of organizing the iterative computing process was effective and useful. Its application can significantly reduce the complexity of software development, as it is based on the formalization and standardization of operations, which simplifies the programming process. In addition, the use of conventional loop statements makes the process of writing programmes more understandable and accessible to developers. The additional array used in the algorithm allows easily changing the configuration of the grid boundaries and the order of operations for each node, which makes the method flexible and suitable for various challenges. A special advantage of the algorithm is its logical simplicity, which contributes to successful adaptation in the case of using multiprocessor systems. Thus, the results of the study confirm the high efficiency and potential of the proposed method for use in practical computing tasks. The proposed method of iterative computation is of considerable practical importance in the field of software development for numerical modelling, since its use simplifies the programming process and provides flexibility in working with different problem conditions, which makes it an important tool for a wide range of research and practical applications in hydraulic engineering and related fields
Application of resource-saving extrusion technologies and an integrated approach to assessing the plasticity of metal parts in agricultural engineering
Authors: Sivak Roman , Kulykivskyi Volodymyr , Savchenko Vasyl , Sukmaniuk Olena , Borovskyi Viktor
Published: July 2024

Among the promising resource-saving technologies to produce parts with improved performance characteristics, the processes of volumetric plastic deformation of products occupy a prominent place. The research relevance is determined by the need to improve the mechanical properties of deformed metal, increase tool life, and produce high precision stamped products with an appropriate level of technological heredity. The study aims to create the required level of strain hardening and damage resistance of deformed metal and products of complex configuration, which will replace expensive steel grades with cheaper ones with similar service characteristics. To calculate the components of the stress tensor under non-monotonic loading, the anisotropic-strengthening body model is used. The study of theoretical and experimental findings suggests that cold combined extrusion methods should be used to manufacture parts with a flange, which can significantly increase the boundary dimensions and improve the technological heredity of the product. The study presents a methodology for determining the kinematic characteristics of plastic metal flow using analytical functions obtained from experimental studies of the motion of a continuous medium. The tensor approach was used to create a model of damage accumulation under non-monotonic deformation. The presented complex of calculations can be used to determine the stress state and the amount of the spent plastic deformation resource during non-monotonic volumetric deformation with a sufficiently high accuracy, without preliminary heating of the metal. Based on the information on the stress-strain state and the tensor model of damage accumulation, the ultimate forming of parts with a flange was estimated. The practical value of the research lies in the use of the proposed approaches to solve several technological problems of metal processing by pressure when the material undergoes non-monotonic plastic deformation under conditions of bulk stress
Modelling of the hydraulic scheme for loading the sowing sections of sowing machines for energy recovery
Authors: Kravchenko Vasyl , Voitik Andrii , Pushka Oleksandr , Lisovyi Ivan , Korobko Mykola
Published: July 2024

One of the most promising areas for improving the energy efficiency of machines is the use of energy recovery from its source. The study aims to develop a basic hydraulic scheme of the clamping mechanism of the sowing section, which would allow to recovery of the energy of the oscillatory movement of the sowing section relative to the sowing frame. The paper considers the scheme of using hydraulic loading of sowing sections using a single-acting hydraulic cylinder. To collect the energy of the sowing section of the seeder, it is proposed to install a hydraulic motor in the existing hydraulic loading circuit to convert the hydraulic energy of the system into the mechanical energy of rotation of its output shaft and a system of check valves to redirect the working fluid in the system and ensure that the hydraulic motor shaft rotates in one specified direction. The input parameters of this system are unevenness of the soil, design features of the sowing section of the seeder, and forward speed of the seeder. The influence of the main parameters of the hydraulic cylinder, hydraulic accumulator and hydraulic motor of the system on the rotational speed and torque on the hydraulic motor shaft is investigated. The research shows that under certain external conditions, when modelling the system in the MATLAB Simulink software, the forced reciprocating motion of the hydraulic cylinder piston is converted into the rotational motion of the hydraulic motor output shaft, which, under certain system parameters under study, can rotate at a speed of 6-86 rpm, developing a theoretical torque of up to 22 N∙m. The size of the hydraulic cylinder piston has the greatest influence on the output characteristics of the system. The hydraulic accumulator provides smoothing of pulsations, the magnitude of which, like the total pressure in the system, depends on the pressure of its pre-charging. The results of this study can be applied in agriculture to optimise energy use during the sowing process by developing efficient energy recovery systems for sowing machines, which will reduce fuel consumption and negative environmental impact

The relevance of the study, in particular, in the Volyn region, is due to the need to ensure the reliability and efficiency of the energy infrastructure in the face of growing challenges associated with the war between Russia and Ukraine, technological development and ensuring the country’s energy security. The purpose of the study is to develop a model of the optimal switching scheme for the Volyn region’s power grids during blackout to minimize the negative consequences and ensure priority power supply to critical facilities. The methods used include mathematical modelling, simulation, optimization, sensitivity analysis, and others. The study optimized the power grid switching scheme under the risk of war and other crisis situations, including a thorough analysis of various options in the event of a blackout. Taking into account additional aspects of grid safety and reliability, the optimal routes for power transmission, placement of backup power sources were identified and effective algorithms for grid management were developed. By optimizing the grid switching scheme, the damage caused by blackouts can be minimized, and power supply can be restored quickly. The results confirmed that an optimal switching scheme can significantly reduce blackout time and its impact on the economy and the lives of the population. The development of optimal switching schemes for power grids is an important step towards increasing the resilience of Ukraine’s electricity system to crisis situations. The study has highlighted the importance of developing such models to ensure energy security and resilience of the power grid under the threat of blackouts, which affects the practical aspects of power supply management and economic development. The practical significance of the study is to improve strategies for managing the power grid in blackout conditions, contributing to the resilience of energy systems and economic development

Authors: Manzar Shabih
Published: July 2024

Aim: This study aims to find out the incidence of atrial fibrillation new onset in STEMI patients receiving primary PCI Sample: A total of 169 patients have included after sample size calculation by using WHO sample size calculator version 2.0. Study Design: Descriptive cross-sectional study Place and Duration of study: This study was conducted at the Department of Interventional Cardiology of CHU Ibn Rochd to Casablanca (Morooco) March, 2022, To December 2022. Methodology: The inclusion criteria set for data collection were as; all the patients undergoing Primary PCI with age between 40 to 80 years, males and females, patients presented with 12 hours of the onset of chest pain with STEMI to enroll in the study. Whereas, patients who had a previous history of any cardiac-related surgery and known AF, also all the patients suffered AF after trial of cardioversion, and those patients who had ejection fraction less than 20% were excluded from the study. Result: The demographic classification showed the mean age of the patients was 55.96±8.9 with a CI of 54.60 to 57.33 years. The mean height of the patients was 167.34±0.56 with CI of 166.2 to 168.46. The mean weight of the patients was 74.84±0.7 with CI of 73.39 to 76.29 kg. The average BMI of all the patients was 26.7±0.28 with CI of 26.2 to 27.33. The analysis of the data revealed that Atrial fibrillation is more common people who don’t smoke tobacco and are non-diabetic. Diabetic patients are less prone to atrial fibrillation in MI. Conclusion: The prevalence of new-onset of atrial fibrillation was found to be high in elderly age group patients.
Coarctation of the Aorta Discovered Incidentally During Pregnancy
Authors: Aware Brahim Nassour
Published: July 2024

Background Coarctation of the aorta is a narrowing of the aorta most commonly found just distal to the origin of the left subclavian artery. This malformation is mostly discovered in the birth by the systematic palpation of the femoral pulses, but can be later diagnosed at the big child’s even at the adult. Casa Presensation: We report here the case of a 32-year-old young man, who is treated for hypertension since two years and to whom a thoracic scanner realized for the assessment of a chronic cough revealed an aortic coarctation. Conclusions This observation reminds us that resistant hypertension in young adults justifies the search for a curable cause. Concerning the association between pregnancy and aortic coarctation, the literature, less alarming than twenty years ago, encourages a wait-and-see and "armed" attitude by favouring a natural delivery.
Performance Assessment of Presurgical Tests in Temporal Lobe Epileptic Patients
Authors: Pastor Jesús
Published: July 2024

The performance of the presurgical test (preSurg) for temporal lobe epilepsy (TLE) was evaluated via video-electroencephalography (VEEG), electroencephalography (EEG), 99mTc-HmPAO single-photon emission tomography (SPECT) and 1.5 T magnetic resonance imaging (MRI) in a group of 112 men (37.0 ± 1.1 years) and 106 women (39.7 ± 1.1 years) operated on for TLE. The epileptic zone (EZ) was adequately identified to determine whether the patient reached an Engel I grade (EI) at least one-year postop. Accuracy was evaluated by the coefficient α, ranging from 3 (when result = EZ) to 2 (result in the same hemisphere as the EZ), 1 (noninformative result) or 0 (EZ in the contralateral hemisphere). The simplicity of diagnosis was defined as the number of preSurg surgeries needed to identify the EZ. EI was obtained in 85.8% of patients, even though 42.2% had noninformative MRI results. For preSurg α was higher for vEEG, followed by MRI and lower for EEG. The accuracy (combination of sensitivity and specificity) was calculated as follows: VEEG (0.797) > MRI (0.518) > EEG (0.446) > SPECT (0.360). The likelihood positive ratio was more significant, and the likelihood negative ratio was lower for VEEG. Both results indicated the highest discriminatory ability for this study. The most relevant factor for the regression model, in order to predict a good function post-surgical outcome were, from more to less relevant VEEG, MRI and EEG, and the factors were not significantly related to SPECT. EZs in EI patients with low simplicity were identified mainly by VEEG. A very good postoperative outcome can be obtained even in TLE patients with no lesions on MRI. This is a relevant idea, because, even patients without apparent lesions in imaging, should be referred to a specialized center to presurgical evaluation. The VEEG is the most reliable preSurg test and may be the only reliable test for patients with very low simplicity.

Resultados: La intervención revela una acogida positiva del material didáctico empleado, que se traduce en una mejora significativa de la CCI del grupo meta. Discusión: Pese a cristalizar con éxito el proyecto, es latente la resistencia al cambio metodológico de los discentes más tradicionales. Conclusiones: Se atestigua la necesidad de acometer iniciativas interventivas similares a corto y medio plazo.
ЖАНРОВА ПРИРОДА ТА СПЕЦИФІКА ЕВОЛЮЦІЇ ФОРТЕПІАННОГО КОНЦЕРТУ: ІСТОРИКО-СТИЛЬОВИЙ ВИМІР
Authors: Ivanovа Yulia Viktorivna
Published: July 2024

Мета роботи – відстежити шляхи розвитку жанру фортепіанного концерту від моменту його виникнення до сучасності для розуміння специфіки його історичної еволюції, жанрової природи та стильових засад, а також для можливого розширення концертного репертуару сучасних виконавців. Методологія дослідження передбачає поєднання музично-історичного та порівняльного методів. Наукова новизна статті полягає у дослідженні історичного розвитку та трансформації жанру фортепіанного концерту як однієї з домінуючих жанрових номінацій в репертуарі сучасних концертуючих піаністів; виявленні категорії концертності та пов’язаних з нею віртуозності, імпровізаційності та змагальності, як її невід‘ємних виконавських стильових рис, що передбачає широкий спектр художніх і інтерпретаційних можливостей, таких як інтенсивність розуміння у передачі та емоційному вираженні змісту виконуваної музики, прагнення до активної реалізації власних творчих амбіцій. Висновки. Фортепіанний концерт як жанрова номінація від самого моменту свого виникнення і до періоду розквіту в кінці XIX - на початку XX сторіччя, пройшов значний еволюційний шлях, нерозривно пов’язаний із удосконаленням творчих методів композиторів, взаємодією з багатьма музичними формами, жанрами та стилями, технічним вдосконаленням самого інструменту, та досягнутим прогресом у художній та технічній виконавській майстерності піаністів. В XX-XXI століттях активний розвиток жанру фортепіанного концерту продовжується та постійно збагачується творчістю сучасних композиторів як у традиційному класичному напрямку, так і в нових, в тому числі синтетичних, формах і жанрах. В контексті цих змін поняття концертності, як невід’ємної стильової виконавської категорії, також зазнає постійної трансформації, що, безперечно, вимагає певної реакції від виконавців, та пошуку ними нових підходів до інтерпретації. Враховуючи безперечну актуальність жанру для концертної діяльності сучасних піаністів, звертається увага на нагальну потребу оновлення та розвинення наукових музикознавчих доробків в цьому напрямку, що може сприяти подоланню певної сталості та одноманітності концертного репертуару для фортепіано з оркестром.
ТЕМБРОВО-АРТИКУЛЯЦІЙНА СПЕЦИФІКА ФОРТЕПІАННОГО ЗВУЧАННЯ ЯК СЕМАНТИЧНИЙ ЧИННИК ТА КРИТЕРІЙ СТИЛЬОВОЇ ПРИНАЛЕЖНОСТІ ФОРТЕПІАННОГО ТВОРУ
Authors: Ziyu Li
Published: July 2024

Мета дослідження – довести призначення темброво-артикуляційних виразових засобів фортепіанної музики як показників стильової приналежності. Дана мета передбачає виявлення деяких типологічних показників фортепіанної стилістики, як такої, що завжди базується на тембрових властивостях інструменту та актуалізується артикуляційним шляхом; також необхідною складовою у вивченні фортепіанного мовлення видається музична темпоральність, яка, у виконавському представленні, унаочнюється у хроноартикуляційному процесі. Методологія дослідження визначається дискурсивним та категоріальним аналітичним підходом, виокремлює текстологічний виконавський метод як провідний та пов’язаний з жанрово-семантичним. Наукова новизна даної статті зумовлюється, по-перше, виокремленням та окремим вивченням, музикознавчою категорізацією темброво-артикуляційних засобів фортепіанного звучання, виявленням їх семантичного та стильового призначення, також можливостей їх авторського композиторського використання. По-друге, вперше вводяться до музикознавчого обігу аналітичні дані про фортепіанний стиль та сонатну творчість сучасного американського композитора Л. Орнштейна, розкривається оригінальність виконавської драматургії його Восьмої сонати. Висновки. Поняття про тембр та артикуляцію потребує звернення до явища фортепіанного тематизму, як узагальненого текстового утворення, що охоплює горизонтальні, вертикальні та поглиблено-об’ємні напрями розвитку композиції, тобто постає багатобічним, але у всіх вимірах пов’язаним з рухом – у часі та у просторі, також у смисловому полі. Різноманітні інтонаційні якості, що виникають всередині тематизму, формуються засобами артикуляції, яка постає, таким чином, як свого роду інструмент використання тембрових можливостей – ресурсів – фортепіано. Підтвердженням даних якостей фортепіанної фоно- та семіосфери, як здатності породжувати власну фортепіанну семантику, знаходимо у творчості Л. Орнштейна, зокрема у циклі його Восьмої фортепіанної сонати.
