Published: January 2025

The study addressed the theoretical analysis of radio relay station control systems using modern information technologies. The study aimed to identify the potential for improving the performance, reliability and cost-effectiveness of such systems. The analysis investigated advanced sensor technologies, automation algorithms and monitoring techniques that could significantly reduce maintenance costs and speed up fault response. Key aspects affecting the performance of radio relay stations were considered, including the impact of climatic conditions and various operational scenarios. The importance of automation integration to improve system reliability and reduce the impact of human error was emphasised. Compliance of the proposed solutions with international radio relay standards, which simplified integration with existing networks and the possibility of future modernisation, was also highlighted. The results of the study substantiated the necessity of automation of radio relay systems and created a theoretical basis for their further development and improvement, which opened new opportunities for improving operational characteristics and increasing resistance to potential failures. The implementation of new approaches to data management and analysis was addressed, ensuring quick response to changes during operation as well as resource optimisation. These aspects provided a competitive advantage in a rapidly changing telecommunications technology environment, emphasising the importance of flexibility and adaptability of systems for efficient operation. As such, the study of the theoretical foundations of automation can be used as a basis for practical recommendations for the implementation of innovative technologies in radio relay station management

The purpose of this study was to analyse the potential of innovative solutions for optimising energy processes and strengthening security systems at military facilities. The study analysed scientific papers, reports, and publications on energy and cyber technologies, using a comparative analysis of approaches to the implementation of renewable energy sources, intelligent control systems and automated technologies at military facilities. The findings confirmed that renewable energy sources (solar panels, wind turbines) reduce dependence on fossil fuels and increase the autonomy of bases. Intelligent energy management systems optimise costs and increase resource efficiency. Microgrids were found to provide a stable power supply even in case of outages. Protecting critical infrastructure using multi-level cybersecurity systems and artificial intelligence significantly reduces the risk of attacks. It was emphasised that microgrids reduce the risk of power outages during crises or cyberattacks, allowing for a quick switch to backup energy sources. Innovative insulation materials and energy-efficient equipment reduce operating costs and improve working conditions for staff. Cyber defence of critical energy systems at military facilities includes multi-level protocols, monitoring of network activity and encryption technologies to prevent cyber-attacks. The use of artificial intelligence to analyse threats allows for prompt detection and response to anomalies. It was proved that innovative technologies are key to ensuring energy independence, security, and efficiency of military facilities. The findings of this study can be used to optimise energy consumption and increase the level of autonomy of military bases, which will ensure the stability of the facilities’ operation even in difficult conditions or in cases of lack of access to external energy sources

On the application of the Bayesian Search Method for detecting underwater objects
Authors: Goncharov Alexander E.
Published: January 2025

Underwater archaeology and, in particular the study of shipwrecked vessels, is one of the more advanced fields in the discipline as it employs a spectrum of technical and scientific methods. Shipwreck detection and identification has been a test ground for a range of theoretical and applied approaches, such as probability theory and mathematical statistics, namely the Bayesian Search Method, which has been successfully applied for this purpose in a number of renowned international projects. In this paper we shall cover the fundamental principles of using this method to assist search efforts in determining the location of historic underwater shipwrecks. As such, the novelty of this paper consists largely in acquainting the Russophone researcher with the Bayesian Search Method in submarine exploration as very little has been published on this subject in Russian literature. As will be shown here, there does exist a demand for the application and perfection of probability search methods for underwater archaeology in the country. In 2024, an expedition to the Yenisei Gulf discovered the shipwrecked steamer Tbilisi, which sank in 1943 after striking a mine installed by the Kriegsmarine. Despite having exact charts and knowing the exact coordinates of the shipwreck, the search team had to spend hours in high seas before finally managing to detect the vessel using side-scan sonar. Applying the Bayesian Search Method would have significantly reduced the time and labor intensity of the search. Besides the search method proper, we shall consider the arrangement of a specialized database for the architecture of a suggested software application, the purpose of which is building probability distribution maps to assist the search and identification of shipwrecked vessels.

Authors: Nikiforov Danil L. , Efimov Sergey N.
Published: January 2025

Due to the difficulties that arise when using satellite navigation systems at airfields at present, and the insufficient accuracy of inertial navigation systems, optical measuring systems have again begun to be used to carry out trajectory measurements. However, existing measuring systems have a number of disadvantages. The purpose of this work is to describe a method for increasing the accuracy of trajectory measurements obtained by the goniometric method. The article reviews the main algorithms currently used in trajectory measurements and their shortcomings. An algorithm for frame-by-frame post-flight processing of recorded video from cameras of an optical-electronic measuring complex is proposed. A description of the implementation of this algorithm is given, taking into account the specifics of graphical software interfaces for processing user of the algorithm’s input. The proposed algorithm allows, after carrying out trajectory measurements, without time restrictions, to correct pan and tilt of the platform at each moment in time. The proposed algorithm makes it possible to increase the accuracy of trajectory measurements when testing aircraft, both already carried out and future ones. The proposed algorithm can also be used to obtain would-be pan and tilt of the camera when implementing a goniometric direction-finding complex using fixed wide-angle optical cameras. For example, when measuring the radiation patterns of an aircraft's onboard antennas using a quadcopter-meter to determine its position in space at each moment in time. The article also presents the main advantages and disadvantages of the algorithm, makes proposals for its improvement, and suggests possible areas of its application.

Published: January 2025

The article considers the design and development of a computer model of the fueling monitoring and control panel of the Sukhoi SuperJet 100 civil aircraft. The presented model is included in a simulator program for training technical specialists in aircraft maintenance skills under conditions of limited access to real or hardware-simulated equipment.
In the process of designing of the presented simulation model, the refueling panel and the SSJ-100 aircraft refueling system sufficient components were considered and selected for further software implementation. The selection of the necessary components for the model was carried out using the decomposition method of the real system. First, the functional elements of the refueling panel itself were selected, after which the refueling system was disassembled into components that allow simulating the operation of the simulated panel.
To implement the simulation model, software classes of objects and interactions between them were described. Software algorithms are implemented in the Unity environment using the C# language. The created program uses a three-dimensional graphic component and compiled for launching on a web browser. Software components have also been developed that allow studying the functions of the fueling panel both independently and in the mode of control of knowledge of the elements and algorithms for working with the fueling panel.
The developed model is used as part of a practical simulator at the Reshetnev Siberian State University, and can be functionally expanded in the future.
Increasing the positioning accuracy of the GLONASS system
Authors: Timofeev Aleksandr L. , Sultanov Albert Kh. , Meshkov Ivan K. , Gizatulin Azat R.
Published: January 2025

The accuracy of determining coordinates in global positioning systems is determined by the number of satellites simultaneously visible to the consumer's navigation equipment. Over most of the earth's surface, there are up to 11 GLONASS satellites above the horizon at the same time, but the signal-to-noise ratio in the communication channel required for error-free information reception is often ensured only for 2-4 satellites. To improve the positioning accuracy, it is proposed to use the holographic noise-immune coding method based on the holographic representation of the digital signal. The message coding process is a mathematical modeling of a hologram created in virtual space by a wave from the input signal source. It is shown that the holographic representation of the signal has significantly greater noise immunity and allows restoring the original digital combination when most of the code message is lost and when the coded signal is distorted by noise several times exceeding the signal level. The studies have shown that the introduction of holographic coding in the GLONASS satellite communication channel will enable consumer navigation equipment to receive information from a larger number of satellites, which will significantly improve the positioning accuracy. In a common situation where the required signal-to-noise ratio is maintained for only 4 GLONASS satellites, the positioning error exceeds 10 meters. Using holographic coding in the same situation, information from 9 satellites will be decoded without error, and the positioning error will be about 2 meters.
Review of problems and methods of calibration of space magnetometers based on anisotropic magnetoresistive effect
Authors: Melent’ev Denis O. , Piskazhova Tat’jana V. , Doncova Tat’jana V.
Published: January 2025

Instruments measuring the Earth's magnetic field are widely used in the space industry. Increasingly, low-orbit spacecraft orientation and stabilization systems include magnetometers manufactured using magnetoresistive technology. This is justified by the low weight, size and consumption of such devices, which makes them ideal for use on small-sized spacecraft. However, the main problem of magnetoresistive magnetometers is the need to estimate possible measurement errors. The influence of errors significantly reduces the accuracy characteristics of the device. In order to solve the problem, researchers propose various methods for evaluating and eliminating the influence of errors on measurements [1–7]. Among the ways to eliminate errors in the readings of the device, constructive solutions are used, such as putting the device at a distance from the spacecraft using a retractable boom, in order to reduce the influence of interference on the device from the device [2]. Such a solution is advisable for large spacecraft, where the presence of a retractable boom will not complicate the design and will not increase energy consumption. For small spacecraft, such a solution is not advisable, for this reason, when discussing small-sized spacecraft magnetometers, much attention is paid to calibration methods, mathematical evaluation and error correction, both in ground and in flight conditions. The objectives of the article include the formation of a general understanding of the causes of distortions in the readings of anisotropic magnetoresistive magnetometers, methods of their mathematical evaluation. A review of methods and equipment for ground calibration is carried out. The characteristics of the calibrated parameters of magnetometers are given and a mathematical model of measurement of the device is proposed, taking into account errors. The basic operations and equipment used in the calibration process are described. The results of the work can be useful in designing workplaces for calibrating magnetometers, as well as in conducting empirical research in the field of magnetometric sensors.

Published: January 2025

Electrical discharge machining and electrochemical machining of metals are used in the production of parts for aircraft and rocket technology, especially electrical discharge machining. A type of electrical discharge machining, electrical contact machining, is used in metallurgy. The paper investigates a combined method of metal machining, including electrical contact and electrochemical methods using vibration of the electrode tool. This method is used for copying and piercing operations in the manufacture of parts from metals that are difficult to machine mechanically. The peculiarity of the above-mentioned method of electrical machining is the formation of surface roughness of the metal being machined due to anodic dissolution and the electrical discharge machining process. The side surface of the workpiece is formed due to electrochemical processes. The end surface is formed due to electrical contact machining. Based on literature data for pulsed electrochemical machining and experiments, expressions for calculating the roughness parameter of the side surface are obtained. The formula takes into account the time of anodic dissolution for one period of oscillation of the cathode tool, the voltage on the electrodes and the concentration of the electrolyte. The calculation of the roughness parameter of the end surface is carried out similarly to the expression for electrical discharge machining, but instead of the duration of the electric pulse, the duration of contact of the electrodes is used. The experiments carried out confirmed the correctness of the expressions used and made it possible to obtain the dependence of the coefficient on the vibration frequency of the cathode-tool.

Published: January 2025

The use of artificial intelligence (AI) in medical diagnostics opens new opportunities for analyzing complex medical images and optimizing diagnostic processes. One of the key challenges remains the interpretation of results obtained through AI systems, particularly in medical practice, where ensuring transparency and clarity of decision-making is critically important. This study proposes a method for visualizing and interpreting the results of cardiac disease classification based on MRI image analysis using deep learning models. The primary goal of the research is to explain AI-driven decisions in a convenient and understandable format for physicians, contributing to the reduction of subjectivity in clinical practice.During the research, approaches were developed for visualizing key groups of medical indicators, such as heart volumes, ejection fraction, myocardial wall thickness, and volume-to-mass ratios. The study describes numerical metrics commonly used in medical practice. Fifteen key medical metrics were identified and grouped into corresponding categories for effective representation of essential medical indicators. Various visualization forms were utilized to ensure intuitive data presentation: pie charts to demonstrate ratios, the 17-segment myocardial model for analyzing wall thickness, and numerical indicators for accurately displaying volumes and ejection fraction. This approach allows physicians to quickly assess structural changes in the heart and make informed conclusions.The proposed method aims to enhance transparency and trust in AI by providing comprehensible data representation, reducing the risks of subjective interpretation and cognitive biases. The results indicate that using such visualizations can significantly facilitate clinical decision-making, improve diagnostic accuracy, and standardize approaches to medical data analysis.

Published: January 2025

This paper evaluates and analyzes multilevel parallelism on a chip multiprocessor (CMP) architecture. The environment is based on the experimental IBM BG/Cyclops architecture, where we have run the multi–zone parallel benchmarks. Multilevel parallelism is spawned using the Nanos OpenMP execution environment. We have performed the analysis with different execution parameters in order to evaluate different hardware threads distributions, cache utilization, and thread grouping configurations. Our results demonstrate that a large number of thread groups and good balancing algorithms are critical for high performance. We also show that a small number of threads can share the same data cache to increase the performance, but a large number of threads should better not share the same data caches.
CyNC: A method for real time analysis of systems with cyclic data flows
Authors: Schioler Henrik , Nielsen Jens Dalsgaard , Larsen Kim G. , Jessen Jan
Published: January 2025

The paper addresses a novel method for performance analysis of distributed realtime systems with complex, and especially cyclic data flow graphs. The presented method is based on Network Calculus principles, where flow and service constraint functions are used to bound data flows and processing resources. In acyclic systems flow constraints may be propagated through a system of service models along data flow paths, whereas service constraints are propagated along paths of priority order. For cyclic data flows however constraint propagation becomes equivalently cyclic leading to flow and service constraints implicitely given by a fix point equation in a space of constraint functions. In this paper a method denoted CyNC for obtaining a well defined solution to that problem is presented along with a theoretical justification of the method as well as comparative results for CyNC and alternative methods on a relevant example. The method is implemented in a prototype tool also denoted CyNC providing a graphical user interface for model specification based on the MATLAB/SimuLink framework.

Published: January 2025

A new method to find first integrals of ordinary differential equations (ODEs) is presented. The approach is based on the complete integrability of the Pfaffian system associated with the ODE, and it does not require the use of symmetries or integrating factors. Examples of second-, third-, and fourth-order ODEs are provided to illustrate the method, including cases where classical approaches fail. This work extends the range of tools available for the analysis and solution of ODEs.
Mitigating the Negative Emotional Effect of Workplace Ostracism on Knowledge Hoarding in Hotel Employees: Beneficial Roles of Core Self-Evaluation and Proactive Personality
Authors: Zhong Jimmy Y. , Sarwar Aisha
Published: January 2025

This study delved into the relationship between workplace ostracism and knowledge hoarding among employees, a critical concern for corporations striving for innovation. Leveraging Affective Events Theory (AET), we hypothesized that workplace ostracism fosters knowledge hoarding, potentially mediated by negative emotions. In addition, we proposed that proactive personality and core self-evaluations could moderate this connection. Utilizing a time-lagged research design, survey data were gathered from 332 employees in Pakistan's hospitality service sector. Our findings revealed that workplace ostracism indeed spurred knowledge hoarding, with negative emotions acting as a mediator. Moreover, we observed that this link was stronger among individuals with lower levels of proactive personality and core self-evaluation, in line with our hypotheses. From a practical standpoint, our study provides management with valuable insights for mitigating knowledge hoarding and workplace ostracism. Overall, our contribution lies in the development and validation of a moderated mediation model that sheds light on the overlooked dynamics between workplace ostracism and knowledge hoarding among hotel employees in the Asian context of Pakistan.
Time-Resolved Hubble Space Telescope UV Observations of an X-Ray Quasi-Periodic Eruption Source
Authors: Wevers Thomas , Guolo Muryel , Lockwood Sean , Mummery Andrew , Pasham Dheeraj R. , Arcodia Riccardo
Published: January 2025

X-ray quasi-periodic eruptions (QPEs) are a novel mode of variability in nearby galactic nuclei whose origin remains unknown. Their multi-wavelength properties are poorly constrained, as studies have focused almost entirely on the X-ray band. Here we report on time-resolved, coordinated _Hubble Space Telescope_ far ultraviolet and _XMM-Newton_ X-ray observations of the shortest period X-ray QPE source currently known, eRO-QPE2. We detect a bright UV point source (\(L_{FUV} \approx \text{few} \times 10^{41}\) erg s-1) that does not show statistically significant variability between the X-ray eruption and quiescent phases. This emission is unlikely to be powered by a young stellar population in a nuclear stellar cluster. The X-ray-to-UV spectral energy distribution can be described by a compact accretion disk (\(R_{out} = 343_{-138}^{+202}R_g\)). Such compact disks are incompatible with typical disks in active galactic nuclei, but form naturally following the tidal disruption of a star. Our results rule out models (for eRO-QPE2) invoking i) a classic AGN accretion disk and ii) no accretion disk at all. For orbiter models, the expected radius derived from the timing properties would naturally lead to disk-orbiter interactions for both quasi-spherical and eccentric trajectories. We infer a black hole mass of log\((M_{BH}) = 5.9 \pm 0.3\) M⊙ and Eddington ratio of 0.13\({}_{-0.07}^{}\); in combination with the compact outer radius this is inconsistent with existing disk instability models. After accounting for the quiescent disk emission, we constrain the ratio of X-ray to FUV luminosity of the eruption component to be \(L_X/L_{FUV} > 16 - 85\) (depending on the intrinsic extinction).

Authors: Gowda R Jeevitha
Published: January 2025

BACKGROUND: Dementia is a growing public health concern in India, with an increasing prevalence among the elderly population. Early detection is crucial for effective intervention. Primary healthcare (PHC) centres play a vital role in identifying cognitive impairment; however, the effectiveness of cognitive screening tools in these settings is questionable.

OBJECTIVE: This scoping review explores the cognitive screening tools available for dementia detection in PHC centres in India, assesses their effectiveness, and identifies the need for their improvement and adaptation.

METHODS: A systematic search was conducted in PubMed, Scopus, and Google Scholar for studies published up to October 2024. A total of 29 studies were identified, indicating that tools such as the Mini-Mental State Examination (MMSE) and the Montreal Cognitive Assessment (MoCA) are frequently used. However, these tools face significant challenges related to educational background and language comprehension, impacting their effectiveness.

CONCLUSION: There is an urgent need for culturally and linguistically appropriate cognitive screening tools in PHC settings in India to enhance the early detection of dementia.
What’s In a Name? On the Problem of Meaning-Change
Authors: Meixner Uwe
Published: January 2025

This article examines the phenomenon of meaning-change in general names, emphasizing its linguistic, philosophical, and societal dimensions. It explores the role of conventions in establishing the relationship between general names and their meanings, highlighting how shifts in meaning can impact language and communication. Structural categories of meaning-change—saliently: strengthening, weakening, and conceptual exclusivity—are presented, along with illustrative examples. The study also proposes a rational framework for evaluating meaning-changes, offering three key precepts: preferring meaning-distinction over change, favoring reform over revolution, and appropriately incorporating moral considerations. Additionally, the implications of politically driven meaning-changes and the challenges of semantic relativism are addressed. The findings aim to provide a nuanced understanding of how meaning-change occurs and guidelines for navigating this process in theoretical and practical contexts.

The Prosecutor's Office plays a vital role in law enforcement as a public prosecutor, contributing to the administration of justice. This study focuses on analyzing the Constitutional Court's Decision Number 6/PUU-XXII/2024 regarding the judicial review of Article 20 of the Prosecutor's Office Law through the lens of Islamic justice principles as proposed by Wahbah Zuhaili. Employing normative legal research methods with a statute and case approach, this study relies on library-based legal materials. The findings reveal two key points: First, the Constitutional Court partially upheld the Applicant's argument, basing its judgment on Article 1 paragraph (3), Article 24 paragraph (1), and Article 27 paragraph (1) of the 1945 Constitution, which address the qualifications for appointing the Attorney General, particularly concerning individuals affiliated with political parties. Second, from the perspective of Wahbah Zuhaili's concept of justice in Islam, the decision deviates from justice rooted in transcendental values derived from the Qur'an and Hadith, as it fails to promote social welfare and collective happiness

This work is devoted to the study of the unmanned aerial vehicle movement model. Attention is focused on the issue of studying the forces that determine the dynamics of movement, the resultant force is considered. Based on the fact that the equation of motion depends on the structural features and purpose of aircraft, and their arsenal is quite varied and multifaceted, the basis of the study is the tactical and technical characteristics (TSH) of operational-tactical missile systems.
The model on the passive part of the trajectory, where the nature of the equation of motion is determined only by gravity and aerodynamic forces, is considered in the paper. Taking into account the maximum flight height and the probabilistic nature of errors in the calculations, it is proposed to consider the force of gravity as constant along the entire trajectory. Therefore, all efforts are directed at determining the numerical values for determining the aerodynamic force. TSH missiles are of great importance here. It is worth noting that there are no real and reliable data about the rocket, in particular its design and experimental data. They are either classified, or unreliable in advance (deliberately presented with some error), or are established experimentally with a certain degree of accuracy or probability. That is why the numerical values given in the paper should be taken as probabilistic.
In the active part of the movement trajectory, the main attention is paid to determining the engine's thrust. The given numerical values characterizing its force, the tabulated experimental values are conditionally correct, but the errors are insignificant. Data on the natural forces of air movement are even more uncertain.
This made it necessary to compare different types of rocket and determine «conditionally» correct values. Based on the proposed mathematical model, it is possible to solve the task of predicting the navigation of an unmanned aerial vehicle with the numerical values of its main characteristics and other necessary input data. This will make it possible to study and form optimization flight trajectories.

Published: January 2025

Introdução: As lesões malignas primárias da vagina são atípicas, e sarcomas vaginais ainda mais incomuns. Leiomiossarcomas retratam menos de 2% das neoplasias malignas ginecológicas, e apenas 10% destes ocorrem fora do útero. Relato do caso: Mulher, 39 anos, gestante, procurou atendimento médico apresentando dor e sangramento vaginal. Foram constatados útero gravídico e massa sólida vaginal que se estendia para gordura adjacente. Na 35ª semana de gestação, foi realizada uma cesárea com exérese da tumoração que posteriormente foi submetida à análise anatomopatológica, sendo diagnosticada como leiomiossarcoma de vagina. Conclusão: A exérese da tumoração, neste caso, foi a abordagem escolhida levando em conta fatores como apresentação do caso, experiência dos médicos envolvidos e disponibilidade de recursos no hospital onde a paciente foi atendida. De fato, não há guidelines específicos para esse tipo de apresentação de leimiossarcoma vaginal, o que implica em individualização de cada caso, com condutas terapêuticas variadas, respeitando as particularidades de cada paciente.

Introdução: O DNA tumoral circulante (ctDNA), um dos principais expoentes da biópsia líquida, constitui uma ferramenta promissora na área da oncologia. Contudo, seu uso na prática clínica, apesar de variado, necessita de maiores embasamentos. Objetivo: Avaliar o impacto da utilização do DNA tumoral circulante como ferramenta para qualificar o prognóstico de pacientes com tumores malignos sólidos do trato gastrintestinal. Método: Revisão sistemática baseada em estudos do tipo coorte, utilizando as bases de dados MEDLINE, LILACS, SciELO, Science Direct e BASE. A avaliação da qualidade metodológica foi feita pela Newcaslte-Ottawa Quality Assessment Scale. Resultados: Dos 557 artigos encontrados inicialmente, a amostra final do presente estudo contou com 13 artigos. Observou-se maiores taxas de recidiva tumoral e menores taxas de sobrevida em pacientes ctDNA-positivos com tumores de todos os principais sítios do trato gastrintestinal, em relação àqueles ctDNA-negativos. Esta correlação foi consistente ao longo de todos os estágios tumorais. Ademais, o ctDNA se mostrou mais eficaz na predição de recidiva tumoral comprovada por exame radiológico quando comparado ao antígeno carcinoembrionário, tipicamente utilizado nesse contexto. Conclusão: Os resultados encontrados apoiam a utilização do DNA tumoral circulante no cenário descrito, de modo complementar às ferramentas de avaliação de prognóstico comumente utilizadas na prática clínica atual.

The study focused on improving kindergarten teachers’ ability to nurture early numeracy development and learning in K2 children. An intervention involving the experimental group included teachers who had already attended in-service training, as part of the initial pilot project, to assist them to understand pedagogical principles, practices and strategies to assist children’s development of numeracy skills, problem solving and reasoning. Further teacher guidelines, detailed lesson plans and mentorship were also provided on how to implement this in the classroom.

The research adopted a pre-test and post-test mixed-methods design involving an experimental group and a control group, comprising preschool children from five classes (N=221). Intact classes were matched to treatment and control conditions on the basis of Mendaki selection and centre choice of participation.
Findings from the Math reasoning subtest of the (WIAT) Wechsler Individual Achievement (Test 2) and the (NCT) Numeracy Concept Test – a non-standardised test, showed that even though that at pre-test, the experimental groups were better on the WIAT and that they were similar on the NCT, both groups improved on the WIAT at post-test but the experimental groups maintained their superior performance on the post NCT. Improvements within experimental groups were also noted.
A implantação do Piscinão de Ramos e suas consequências nas dinâmicas urbanas e sociais dos moradores do Complexo da Maré – uma abordagem sociotécnica
Authors: Sbarra Marcelo
Published: January 2025

Neste artigo nos propomos a entender como a implantação do Piscinão de Ramos, dentro do contexto do Complexo da Maré e da própria Praia de Ramos, no Rio de Janeiro, constituiu uma importante e complexa modificação na ambiência urbana local e nas relações que se estabeleceram a partir deste marco urbano. A partir desta contextualização, em uma abordagem sociotécnica, busca-se estabelecer a relevância do Piscinão de Ramos em reestabelecer e reconfigurar dinâmicas urbanas e sociais no macrocosmo urbano do Complexo da Maré. Ao final, mostramos como este entendimento é fundamental para compreender os impactos e as implicações da implantação deste tipo de ícone urbano, permitindo uma análise crítica e reflexiva sobre o tema.
ДЕЯКІ АСПЕКТИ КОРЕКЦІЇ РОЗВИТКУ ШКОЛЯРІВ З ПОРУШЕННЯМИ ІНТЕЛЕКТУ НА УРОКАХ ТРУДОВОГО НАВЧАННЯ

Published: January 2025

У статті досліджено окремі питання корекції розвитку дітей з порушеннями інтелекту на уроках трудового навчання. Підкреслено необхідність формування в школярів з інтелектуальною недостатністю таких необхідних вмінь та навичок як усвідомлення завдання, планування діяльності, самоконтроль та самооцінка. Розглянуто етапи планування, види самоконтролю. Зазначено, що з метою корекції розвитку дітей з інтелектуальними порушеннями вчитель має проводити корекційну роботу системно та цілеспрямовано. Крім висвітлення питань корекції інтелектуальної сфери, стаття торкається можливостей уроків трудового навчання для стимуляції розвитку загальної та дрібної моторики. Зазначено доцільність використання з цією метою сучасних засобів художньої праці (вироби із бісеру, природніх матеріалів, специфічні вироби з паперу, квітникарство, писанкарство, лозоплетіння тощо).
Assessment of Urban Bias in Iberian Butterfly Sampling through Citizen Science Data
Authors: Gil-Tapetado Diego , Alamo Mario
Published: January 2025

Citizen science platforms have revolutionized biodiversity monitoring by enabling large-scale data collection. However, concerns about potential biases, such as urban sampling bias, have raised questions about the quality and representativeness of these datasets. This study assesses the spatial distribution of butterfly observations collected through the citizen science platform Biodiversidad Virtual in the Iberian-Balearic region over a 23-year period (2000–2023). Butterfly records were classified into three ecosystem types—urban areas, grasslands, and forests—and three population density zones—urban, peri-urban, and rural areas—using land cover and population density maps. Temporal trends in observation growth and minimum distances of records to urban and rural areas were analyzed. The results show consistent growth in butterfly observations across all ecosystem types, with rural and natural areas contributing significantly more records than urban areas. Observations in grasslands exhibited the highest growth rate, followed by forests and urban areas. The analysis of distances revealed preference for recording biodiversity in natural areas, with records consistently closer to rural areas than urban centers. These findings challenge the perceived dominance of urban bias in citizen science datasets and highlight the capability of citizen science platforms to capture data from diverse ecosystems. This study shows that, for one of the most important georeferenced datasets on butterflies of the Iberian Peninsula, urban biases are minimal, and geographic representation is robust. Further research is recommended to examine cultural and regional factors in other databases, enhancing their application in ecological research and conservation planning.

This chapter highlights key concepts and techniques for transformative roleplaying game design. Working with myth, symbolism, and ritual are age-old practices that can deepen the role-playing experience and its impact. We explore narrative work and postmodern magic as methods for transforming the stories of our lives. We also discuss the many forms of culture within and around RPGs, as well working with conflict in scenarios related to politics, culture, gender, sexuality, race, and ethnicity. We close with thoughts around the use of RPGs to foster activism, advocacy, inclusion, and accessibility.

In this chapter, we highlight the many theories and concepts that have informed our theoretical framework and curriculum in transformative game design. Reflecting our interdisciplinary backgrounds, these theories arise from role-playing game studies, peace and conflict studies, psychology, social psychology, sociology, counseling, pedagogy, anthropology, and several other fields. Key concepts include bleed, alibi, RPGs as transformational containers, immersion, identity, transfer, ritual, psychotherapeutic techniques, various interaction theories, and educational theories, among others.
