Published: January 2025

Grade progression of well-differentiated pancreatic neuroendocrine tumors (panNETs) can occur over time, with G1/2 to G3 being the most clinically relevant form. Here, we conducted a retrospective cohort study of 66 patients with initially G1/2 panNET (median initial Ki67, 4.6%). Patients were followed up for a median 6.8 years and had a median of two metachronous tumor biopsies over their disease course. 34.8% of patients underwent any form of grade progression, including G1 to G2/3 and G2 to G3, while 24.2% demonstrated G1/2 to G3 grade progression. Over a median 2.3 years, G1/2 to G3 grade progressors experienced a median Ki67 change of +27.0% (range, +6.4 to +48.7%). Subsequent biopsies showing progression to G3 had a median Ki67 value of 31.0% (range, 21.0–60.0%) and were more often performed following suspicious clinical behavior (75.0%) rather than routinely at the time of scheduled procedure/surgery (25.0%). Similar to prior studies, G1/2 to G3 grade progressors had worse overall survival from the time of metastatic disease (median, 4.8 years vs not reached for stably G1/2 disease; P = 0.002). Heavier pretreatment and heterogeneity or lack of uptake on somatostatin receptor imaging was independently associated with progression to G3. In the largest study of metachronous panNET biopsies to date, our findings show that baseline biopsies suggesting G1/2 disease may not accurately reflect future disease status, highlighting the possible limitations of using archived tissue to stratify patients into trials and/or choose future therapy. Additional work is needed to better understand the impact of prior therapies on grade progression and how to identify which lesions to best follow up for repeat biopsy.

Выполнено экспериментальное моделирование острого воспаления в легких у мышей путем ингаляции аэрозоля липополисахарида из микробной клетки Salmonella typhi. Показано, что после ингаляционного аэрозольного введения в течение 60 мин липополисахарида (размер частиц 1.1±0.1 мкм) в дозе 5.3 мкг/кг на (5-7)-е сутки наблюдается выраженное гемодинамическое и эмфизематозное обратимое изменение в легких, характерное для острого воспаления легких.

Experimental acute lung inflammation in mice was modelled by inhalation of lipopolysaccharide aerosol from a Salmonella typhi microbial cell. It has been shown that inhalation aerosol administration of lipopolysaccharide (particle size 1.1±0.1 µm) for 60 min at a dose of 5.3 µg/kg leads to a pronounced haemodynamic and emphysematous reversible change in the lungs after 5-7 days, which is characteristic of acute lung inflammation.

Проведены исследования газообразных продуктов пиролиза таблетированных образцов микрочастиц углей марок К (коксовый) и А (антрацит) при воздействии импульсно-периодического лазерного излучения (параметры излучения: 532 нм, 10 нс, 6 Гц, 0.2-0.6 Дж/см2) в среде аргона. Показано, что концентрация газообразных продуктов возрастает по экспоненциальному закону с увеличением плотности энергии лазерного излучения. Превышение критического значения плотности энергии излучения (Hcr = 0.18 и 0.26 Дж/см2 для углей марок К и А соответственно) приводит к абляции угольных образцов. Масса продуктов абляции возрастает с увеличением плотности энергии лазерного излучения по линейному закону.

Gaseous products formed in the pyrolysis of samples composed of the tableted K (coking) and A (anthracite) coal microparticles under the action of pulse-periodic laser radiation (with the parameters: 532 nm, 10 ns, 6 Hz, 0.2-0.6 J/cm2) in the argon environment have been studied. It is shown that the concentration of gaseous products increases exponentially with an increase in the laser radiation energy density. Exceeding the critical radiation energy density values ( H cr = 0.18 and 0.26 J/cm2 for K and A coal ranks, respectively) leads to ablation of coal samples.

Проведено исследование возможности создания электродных нанокомпозитных материалов для суперконденсаторов методом адсорбции солей переходных металлов пористой углеродной матрицей из водных растворов с последующей термообработкой. На примере системы “углерод - Co3O4” показано, что данным методом могут быть получены нанокомпозиты с содержанием наполнителя (элементарного кобальта) до 3 мас. %. Введение наполнителя подобным способом в незначительной степени снижает удельную поверхность и объем пор композитов по сравнению с исходной углеродной матрицей. Получаемый при термическом разложении нитрата кобальта(II) при 240 °C продукт не удается идентифицировать методом рентгенофазового анализа, однако по данным дифференциального термического анализа он катализирует термоокисление пористой углеродной матрицы на воздухе. С использованием циклической вольтамперометрии показано, что полученные методом адсорбции исследуемые электродные материалы обладают более высокой удельной емкостью по сравнению с исходной углеродной матрицей или композитами, полученными методами внедрения наполнителя в виде твердой фазы.

The possibility of making electrode nanocomposite materials for supercapacitors by adsorption of transition metal salts from aqueous solutions by the porous carbon matrix with subsequent heat treatment has been investigated. It is shown for the carbon - Co3O4 system as an example that this method allows obtaining nanocomposites with the content of filler (elemental cobalt) up to 3 wt%. The introduction of the filler using this method only slightly reduces the specific surface area and pore volume of the composites with respect to the initial carbon matrix. The product obtained by thermal decomposition of cobalt(II) nitrate at 240 oC cannot be identified by X-ray diffraction, but according to the data of differential thermal analysis, it catalyses thermal oxidation of the porous carbon matrix in air. It is shown by cyclic voltammetry that the electrode materials obtained by the adsorption method have a higher specific capacitance compared to the original carbon matrix or composites obtained by inserting the filler as the solid phase.

ИНТЕГРИРУЕМОСТЬ ДИФФЕРЕНЦИАЛЬНЫХ УРАВНЕНИЙ И "КОНВЕРТАЦИЯ СЛОЖНОСТИ"
Authors: СУХНО А.А. , ГУЛИН В.В.
Published: January 2025

В статье исследуется ситуация, которая сложилась вокруг дифференциальных уравнений как инструмента естествознания. С одной стороны, в рамках «тихой научной революции» XVIII в. они позволили преодолеть ограничения человеческой интуиции и раскрыть потенциал аналитических методов для познания природы. С другой стороны, к концу XIXв. проблема интегрируемости дифференциальных уравнений, наиболее ярко заявившая о себе в связи с «задачей nтел», показала необходимость реабилитации интуиции как важнейшего фактора научного познания. Именно с обращением к интуиции связано создание качественных/геометрических методов исследования нелинейных систем. В результате анализа этой ситуации в статье делается вывод об изменениях, происходящих на уровне методологии при столкновении научного познания со своими пределами: здесь выбор математических инструментов осуществляется таким образом, чтобы «сложность» одного из элементов исследовательской ситуации, которая стала для познания непреодолимой преградой, переносилась на какой-то другой элемент. Эта «конвертация сложности» позволяет продвинуться вперед в изучении природы.

The article examines the situation around differential equations as a tool of natural science. On the one hand, during the “Quiet Scientific Revolution” of the 18th century, they made it possible to overcome the limitations of human intuition and reveal the potential of analytical methods for understanding nature. On the other hand, by the end of the 19th century, the problem of integrability of differential equations, which most clearly manifested itself with regard to the “n-body problem,” showed the need to rehabilitate intuition as the most important factor in scientific knowledge. It was the appeal to intuition that determined the creation of qualitative/geometric methods for studying nonlinear systems. Based on the analysis of this situation, the article draws a conclusion about the changes in methodology when scientific knowledge meets its limits: here the choice of mathematical tools is made in such a way that the “complexity” of one of the elements of the research situation, which has become an insurmountable barrier for knowledge, is transferred to some other element. So, this “complexity conversion” allows progress in the study of nature.

Introduction. The advent of Bruton’s tyrosine kinase (BTK) inhibitors brought about a paradigm shift in the management of chronic lymphocytic leukemia (CLL), by offering a well-tolerated chemotherapy-free approach. Here, we share the experience with ibrutinib of a major Romanian regional cancer center.
Methods. We screened patients treated for CLL in our center over 6 years (2017- 2022) and included those who were treated with ibrutinib either in the first line of therapy or in subsequent lines.
Results. We enrolled 61 patients, 40 with treatment-naïve (TN) CLL and 21 with relapsed/refractory (R/R) CLL, with a median age at treatment initiation of 65 years. Concerning the prognostic-predictive workup, IgHV mutational status was available for 78.7% of the patients, TP53 sequencing for 82%, assessment of 17p deletion for 82%, and CD38 marker analysis was performed for 70.5%. With a median follow-up period of 55 months, the overall response rate (ORR) was 90.2%, with a median progression-free survival (PFS) of 33 months and a median overall survival (OS) that has not been reached. In our cohort, albeit non-significant statistically, patients with TP53 mutation had a shorter OS and those with mutated IgHV, a shorter PFS. Rai 3-4 and Binet C stages at diagnosis were associated with a shorter PFS, but not OS. In our cohort, the correlation between survival and high Cumulative Illness Rating Scale (CIRS) index was not statistically significant. Ibrutinib was generally well tolerated in our cohort, as only 14.8% of our patients discontinued treatment due to adverse effects.
Conclusion. Our study suggests that ibrutinib is a valid therapeutic option for TN or R/R CLL patients, with a high ORR and a good safety profile.

Test takers’ characteristic is an exciting topic to discuss in psychometric research. In this study, person-fit is a part of the person characteristics applied in the context of cognitive tests. Given the importance of accurately estimating item and person parameters, person-fit is a statistical technique that can detect aberrant responses. Aberrance adversely affects the estimation process at the level of items and persons. The purpose of this study was to introduce and apply two popular person-fit statistics called and . These two statistics were applied in two studies, in study 1 using N = 317 and item = 16, and in study 2 using N = 331 and item = 49. The results showed that in studies 1 and 2,  detected more aberrant responses compared to . Significant differences in estimated results from both techniques were also shown in Study 2. The outcomes of this study are valuable for researchers and practitioners in the field of psychometrics who rely on , as a foundation for identifying aberrant responses.

Abordar la crisis socioambiental global —manifiesta también localmente tanto en lo urbano como en lo rural— requiere un enfoque complejo que integre al diseño con otras disciplinas y con una perspectiva ética que pueda enfrentarla de modos distintos a los dominantes, cuyo fracaso es evidente. Experiencia Arbórea, desde un enfoque tal, busca contribuir a solucionar el conflicto entre necesidades de vida digna para habitantes rurales y citadinos, habitabilidad ecoconsciente y la imperante necesidad de cuidado de los ecosistemas, a partir de la comprensión compleja de necesidades y perspectivas de los involucrados en la problemática y sus soluciones, y, en particular, del rol de comunidades anfitrionas como cuidadoras del territorio.
Por su parte, vision in design, método de investigación a través del diseño, parte de la premisa de que los sistemas producto-servicio obtienen su significado en la interacción con las personas, cuya idoneidad está determinada por el contexto, elemento clave del enfoque complejo y ético desde el que se desarrolla el proyecto. Desde este enfoque y metodología, la inspiración para la propuesta fue el árbol, un sistema vivo que impulsó nuestra apuesta ética y permitió definir una experiencia, materializada en un espacio de conexión social, cultural y natural, a partir del cual se configura el sistema producto-servicio: un servicio de ecoturismo; el Nido, artefacto para hospedar temporalmente a visitantes; y aquellos elementos comunicantes de su conceptualización y acción, tales como estrategia de comunicación, imagen y aplicaciones. En este camino, enfrentamos retos —asociados a limitaciones de tiempo, recursos y resistencias culturales— para integrar todos los elementos que la mirada compleja nos permitió reconocer.

Published: January 2025

Leptospirosis significantly impacts beef and dairy cattle production, particularly in tropical regions, although it remains a disease of global relevance. This zoonotic disease primarily causes abortions during the final third of gestation. The present study aimed to analyze the risk factors associated with leptospirosis in the southern Andean region of Colombia. To this end, 360 cattle were sampled across 24 municipalities within the department of Huila. A seroprevalence of 49.2% was determined using enzyme-linked immunosorbent assays (ELISA). These results were subsequently correlated with various variables obtained through epidemiological surveys. The findings revealed that the primary risk factors for leptospirosis were linked to inadequate livestock management practices. These included improper methods of food storage, failure to implement quarantine protocols for infected animals, the introduction of new fattening cattle into the herd without proper precautions, infrequent weighing of animals, poor storage management of veterinary medications, lack of segregation of sick animals, insufficient estrus detection practices, inadequate hand hygiene when interacting with the herd, and the use of unclean instruments during routine procedures. Conversely, the presence of well-defined internal pathways and the separation of poultry production from cattle operations were identified as protective factors. Understanding these risk factors is critical from a One Health perspective, as it facilitates the implementation of preventive measures aimed at safeguarding both animal and human health.
Comprehensive Academic Cybersecurity during Rapid Remote Learning Migration: A Holistic Approach to Security, Privacy, and Accessibility
Authors:   Independent Researcher, Florida, USA, Lakshmikanthan Govindarajan
Published: January 2025

The rapid transition to remote learning during the early 2020 pandemic has catalyzed unprecedented
changes in higher education cybersecurity infrastructure. This white paper presents a comprehensive framework
addressing the multifaceted challenges of securing academic environments during this transformation. Our research
examines not only traditional security concerns but also emerging challenges in student privacy, mental health
considerations, geographical access disparities, and cross-institutional collaboration. Through empirical analysis of
implementation across multiple institutions, we demonstrate how universities can adapt their security architectures to
support widespread remote access while maintaining data protection, academic integrity, and student wellbeing. Our
findings show significant improvements across key metrics, including an 85% reduction in unauthorized access
attempts, 99.9% availability of critical academic services, and a 40% reduction in student-reported technical anxiety
during the transition period. This paper provides technical specifications, implementation guidelines, and empirical
validation of our approach, offering a blueprint for institutions facing similar challenges in the rapidly evolving
landscape of higher education.

Published: January 2025

Where organizations used to rely on employees tenured with their company, the Great Resignation has
presented new problems to organizational structure and fortification. Such a process usually leads to disrupted
employee productivity and most importantly, increased vulnerability to cyber threats. Loyal workers, intentionally or
unintentionally disloyal workers, and employees who leave the organization can compromise organizational
confidential information, such as innovation, customer data, and other data that the organization considers to be highly
valuable. Research has also revealed that workforce transition time is also the highest-risk activity period for insiders,
wherein activities like the unauthorized download of data or accidental data leaks when offboarding an employee are
likely to occur. Moreover, there are difficulties, particularly for organizations that cannot apply adequate access
controls and monitoring during the notice periods, making them much more sensitive to data leaks. Further, this paper
examines these paramount cybersecurity threats and offers an organized framework for their mitigation. Explores how
the risks can be reduced under this through policies like strong access controls, opaque data monitoring systems, and
comprehensive offboarding. To get practical recommendations for managing the problem with data sharing, the
example of using machine learning to realize the mechanisms for identifying anomalies and graph-theory-based
mathematical models is given. Thus, this research provides a comprehensive set of procedures to address the
consequences of the Great Resignation for organizations and safeguard their assets during worker turnovers.
Environmental and HSE audit — modern practices and aspects of specialist training
Authors: Pinaev Vladimir
Published: January 2025

Author provides an overview of modern environmental audit practices in Russian Federation, and also touches issues of technical/integrated audit, including aspects of occupational safety, industrial and fire safety, and environmental protection. The article considers checklists — questionnaires of federal executive authorities, using which the auditor can prepare a specialized questionnaire for conducting an audit at a specific enterprise. In the article, the author presents the theoretical and methodological foundations of environmental and integrated audit in the Russian Federation, indicates the need to develop a regulatory framework to improve the procedure for conducting environmental and integrated audit. Is noted that practice of conducting a fire safety audit (independent fire risk assessment), regulated by regulatory documents of the Ministry of Civil Defense, Emergencies and Disaster Response of the Russian Federation. Attention is paid to the training of auditors. The author concludes that in the Russian Federation there are foundations for the widespread introduction of various types of audit. However, there are no regulatory documents on environmental and integrated audit at the federal level (federal laws). At the same time, the questionnaires (checklists) relevant ministries and departments greatly facilitate the work of auditors. There are no centralized standards for the training of environmental auditors — it seems advisable to develop and adopt them at the federal level in order to unify the quality of auditor training. Attempts to encourage the adoption of documents on environmental and integrated audit by the Ministry of Natural Resources of Russia and the Ministry of Energy have not been successful at the moment. It can be assumed that the saturation of by-laws with the terms and principles of environmental and HSE audit in the future will lead to the adoption of relevant laws/law on environmental and/or integrated audit.
Role of a literary text in teaching reading for professional communication
Authors: Nurieva Nailya
Published: January 2025

The article discusses the role of English literary texts for reading in teaching for the professional communication. The novelty of the study lies in the fact that the competence level of specialist of today is subject to requirements due to innovative processes taking place in various spheres of the global world. The current time has determined the change in the role of a foreign language. Its development is characterized by the multidimensional nature of the target settings. The purpose of the article is to confirm the need to use fiction texts in teaching reading as a resource of regional and authentic linguistic material in building the language competence and correct speech behavior of specific-profile specialists. A detailed analysis of academic publications has shown that reading fiction texts is the basis of learning, but the level of language education lags behind expectations. In this regard, there has been an intensification of academic speculations about the necessity to get the materials of the artistic genre integrated into the process of teaching foreign languages for specific purposes. The author of this work describes the criteria for the selection of fiction (authentic texts by Anglo-American authors; short forms; synchronization). In order to maintain a balance between the demands of modern youth for the content of literary works and samples of generally recognized classical literature, we address the short stories by British and American writers of the turn of the XIX–XX centuries. An attempt is being made to convey the experience of teaching to read prose in the form of a model for selecting texts and processing them for classroom activity as a learning resource. It is believed that implementation of fiction reading contributes to the development of cognitive processes of perception, understanding and interpretation of texts and further development of an authentic language proficiency for professional communication.

Concrete has emerged as a promising solid-based sensible heat storage (SHS) material due to its favorable balance of thermal properties, cost-effectiveness, non-toxicity, and widespread availability. This state-of-the-art review examines the applications of concrete-based SHS across diverse domains, including buildings, concentrated solar power systems, and industrial power generation. It also investigates the thermal properties of concrete relevant for SHS applications and explores the design considerations for concrete SHS systems and reviews the current research landscape and the role of numerical modeling and simulation techniques in optimizing the performance of concrete SHS systems. Various computational methods, such as transient modeling, finite element method (FEM), computational fluid dynamics, and simplified lumped capacitance models, have been employed to analyze and enhance the design of these systems. As research and development continue in this field, several future trends are anticipated.

Published: January 2025

Due to the vast landscape of low carbon concretes that have been or can be developed, traditional empirical methods are impractical for comprehensive assessment of concrete performance. Here, we describe Panoramix 1.0, a Python-based tool that can predict physical and chemical properties of hydrated cements, and durability and environmental impacts of concretes. Applying it to CEM I concrete as a case study, we investigate the cement composition effects on the freeze–thaw resistance indicator (time to critical saturation degree, t

CR
). Results indicate that chemical composition of raw materials including Fe2O3 may influence freeze–thaw resistance, which is usually not considered in the current scheme of durability assessment. The results also show how the design space (i.e., feasible cement compositions) could be found for different types of concrete at specified minimum freeze–thaw resistance. We validate Panoramix by comparing its ranking of 28 concrete samples in terms of freeze–thaw performance (t

CR
) with experimental data for relative dynamic modulus of elasticity (RDME) reported in ten publications and measured using procedures from four different standards. By combining the composition-freeze–thaw resistance modelling with a life cycle assessment model, we show that the climate change impact (100-year global warming potential) per m3 CEM I concrete can be reduced from 313 to 286 kg CO2-eq. by decreasing the clinker-to-cement ratio while reducing t

CR
from 7 to 5.5 years.
Field and numerical assessment of geofoam inclusion behind a rigid cantilever wall
Authors: Bishnoi Dinesh , Dasaka Satyanarayana Murty , Patil Vikas
Published: January 2025

The concept of compressible inclusion was introduced over two decades ago, and earlier studies revealed that providing geofoam compressible inclusion between a retaining structure and backfill significantly reduces lateral pressure. Most studies are either 1-g model or numerical tests, and field tests are necessary to better understand and confirm previous research findings. In the present study, parametric tests are performed on a 6 m high concrete cantilever wall to check the effectiveness of inclusion on a rigid-yielding wall. The wall is instrumented to measure earth pressure, wall deflection, and geofoam compression during the backfilling. Field tests are performed with EPS15_500 (i.e. geofoam density of 15 kg/m3 and 500 mm thickness), EPS15_1000, and EPS20_500, and the results are compared with the control test without inclusion. A developed numerical model is validated with the field results to determine the pressure variation for different cases. EPS15_1000 shows maximum reduction in lateral pressure, wall deflection, and geofoam compression and can be a suitable compressible inclusion for the wall under investigation. The compressive strains generated in expanded polystyrene (EPS), irrespective of EPS density and thickness, exceed the design strains suggested by previous studies. Majority of strains occurred due to compaction, which was not considered by earlier studies.

Published: January 2025

In this study, ultrafine basalt powder (UBP) and basalt sand (BS) were utilized to replace fly ash and quartz sand, respectively, in the preparation of Engineered Cementitious Composites (ECC). The substitution rates of UBP and BS were established at 0%, 25%, 50%, and 100%. Uniaxial tensile experiments were conducted on the prepared ECC specimens to examine the tensile strength and ductility of ECC under varying mix ratios. A constitutive model (L&C) integrating a straight line and a curve was established based on the Sigmoid function. The findings indicate that when UBP was utilized as a complete substitute for fly ash, the ultimate strain, fracture elongation, and tensile strength of ECC exhibited increases of 140.1%, 187.1%, and 44.7%, respectively. In addition, the pseudo strain strengthening coefficients, specifically σ0/σc and Jb/Jtip, increased from 2.30±0.22 and 14.58±1.86 in the control group to 2.97±0.29 and 27.49±1.95, respectively. When BS completely replaced quartz sand, tensile strength decreased by 23.4%. However, the ratios σ0/σc and Jb/Jtip improved from 1.42±0.08 and 13.49±1.18 in the control group to 1.90±0.13 and 19.58±1.51, respectively, enabling ECC to better satisfy strength and energy criteria. Consequently, ultimate tensile elongation and fracture elongation increased by 42.2% and 53.1%, respectively. After conducting a thorough analysis and comparison, it is evident that the L&C model, which is based on the Sigmoid function, demonstrates a higher correlation than the traditional bilinear model.

Analysis of Global Design Standards to Assess Different Levels of Structural Seismic Protection
Authors: Huang Yingbi
Published: January 2025

This research undertakes a thorough examination of the significant social and economic losses resulting from earthquakes throughout time, as well as the considerable destruction inflicted upon physical structures. Using the reinforced concrete frame structure as an illustration, it highlights several types of column damage that might potentially happen to the structure during seismic events. As cross-border projects become more frequent, it is crucial to have precise specification comparisons and parameter conversions as a reference for engineering projects happening worldwide. This article will now analyze and contrast the seismic building designs of China, the United States, Indonesia, and Australia. These nations are selected based on their susceptibility to earthquakes, with China, the United States, and Indonesia being earthquake-prone, while Australia has infrequent seismic activity. An assessment of each country’s standards is undertaken, specifically parameters in relation to seismic defence standards, seismic protection levels, method of determining shear wave velocity, method of determining site subsoil and the implementation of the seismic design response spectrum. An evaluation was made after analyzing each parameter based on the requirements in the standards, and a recommendation for the most practical and reasonable method from one of the countries for each parameter was provided. Overall, seismic standards from China were deemed the most thorough and considerate standard, which not only encompassed a broader range for each parameter but was also deemed the most technical and considerate in terms of parameter derivation.

Применение информационных систем для сбора данных в процессе проведения психологических исследований дает дополнительные возможности по организации эксперимента в среде, приближенной к естественным условиям. Это позволяет произвести максимально точные измерения при создании технологий мониторинга состояния человека в различных контекстах. Целью исследования была апробация автоматизированной системы для сбора данных при исследовании динамики уровня субъективной сонливости.
Была создана автоматизированная система сбора и обработки данных. В исследовании поучаствовали 225 человек. Каждый до эксперимента был проинструктирован, получал доступ к системе и дальше самостоятельно проходил эксперимент, находясь у себя дома. Испытуемым необходимо было внести данные о себе, а затем, начиная с 20 часов до отправления спать каждые полчаса заполнять предложенные опросники, фиксирующие уровень сонливости. Последний раз уровень сонливости отмечался после просыпания в 6 часов утра.
Результаты исследования свидетельствуют о возможности применения автоматизированных систем для оценки динамики субъективной сонливости без потери качества данных. Так, выявленные закономерности согласуются с результатами похожих исследований, проведенных без применения автоматизированных систем.
Персональные данные как объект правового регулирования: соотношение законодательства, общественного мнения и судебной практики
Authors: Мамай Евгений Алексеевич
Published: January 2025

В статье анализируются существующие противоречия между пониманием персональные данных в законодательстве, общественном мнении и судебной практике. Абстрактная формулировка, содержащаяся в статье 3 Федерального закона «О персональных данных» влечет за собой широкую вариативность интерпретации содержания, ценности и механизма охраны персональных данных физических лиц, что находит свое наиболее яркое выражение в отечественной судебной практике. Законодательная дефиниция персональных данных, рассматривая в качестве таковых любую информацию, относящуюся к прямо или косвенно определенному, или определяемому физическому лицу (субъекту персональных данных), включает в себя широкий спектр способов идентификации личности. В тоже время изучение общественного мнения и результатов правоприменительной практики позволяет говорить о существенно ином восприятии объема охраняемой законом информации. В результате проведенного социологического опроса автор пришел к выводу, что большинством населения не в полной мере осознается ценность
их персональных данных, при этом в качестве таковых многими рассматриваются только прямые идентификаторы личности.
Изучение множества дел, рассмотренных российскими судами, приводит к выводу об отсутствии единства правоприменительной практики и, как правило, также суженном толковании судами объема понятия «персональные данные». Подобное противоречие в законодательном определении, социальном восприятии и правоприменении, по мнению автора, обусловлено противоречащими друг другу публичными и частными интересами, столкновение между которыми не может быть разрешено одномоментно.
DYNAMICS OF US-UKRAINIAN DEFENCE COOPERATION (2014-2021): FROM B. OBAMA TO J. BIDEN
Authors:   University of Customs and Finance, Dnipro, Ukraine, Pashkov Viktor
Published: January 2025

The article is devoted to the study of the features of military-technical cooperation between Ukraine and the United States in 2014-2021. In particular, the volumes, nomenclature and goals of American military assistance to Ukraine currently, the main directions of bilateral defense cooperation are described in detail. It is determined that despite certain differences in approaches and emphasis in providing military assistance to Ukraine, the administrations of B. Obama, D. Trump, and J. Biden's administrations demonstrated consistency in logic and goals: Washington provided limited defensive military assistance necessary to deter Russia in the low-intensity conflict in Donbas. At the same time, the biggest qualitative breakthrough in the provision of military assistance occurred during D. Trump's term in office, when in 2017 the United States decided to supply Ukraine with a batch of Javelin ATGMs, thereby lifting the political taboo on supplying Kyiv with lethal weapons.

Demonstrating continuity in the policy of military assistance to Ukraine, at the same time, to the administrations of B. Obama, D. Trump and J. Putin. Biden had different priorities. In 2014-2016 US military aid was limited to non-lethal means, with the aim of reducing the losses of the Ukrainian army in the conflict in the Donbass and not exacerbating escalation. The administration of D. Trump, along with the provision of lethal weapons, paid special attention to reforming the Ukrainian security sector. Instead, he Biden administration has identified strengthening Ukraine's naval capabilities as a priority in providing military assistance.
Navigating a Climate in Crisis through a Biomimetic Epistemology
Authors: McCormick Elizabeth , Thaddeus David
Published: January 2025

We have entered a geological epoch where environmental change is driven primarily by human activity. The technology-centric approach to sustainable development as the dominant model of innovation in industrialized countries has led to expansive ecological degradation. This paper critiques this paradigm and builds on existing literature from environmental philosophy to propose a new model of ethical, bio-inspired architectural thinking. Though Biomimicry is often celebrated as a model for nature-inspired innovation, it can inadvertently reinforce notions of mastery over nature, a harmful phenomenon that environmental philosopher Freya Mathews calls ‘anthropocentric triumphalism.’
In response to those challenges, this paper explores the philosophical underpinnings of bio-inspired design to advocate for a transformative pedagogical model within architectural education and practice. By exploring the conflicts implicit in biomimetic processes, we aim to disentangle students’ thinking from techno-centric models and prepare them for the broader societal implications of a necessary energy shift. This exploration emphasizes the importance of cultivating a holistic understanding of ecological systems, urging designers to appreciate the intricate relationships within ecosystems rather than viewing them solely as sources of technological inspiration.
By addressing the conflicts inherent in biomimetic processes, this paper calls for a more comprehensive and ethical approach to biomimicry – one that emphasizes both the source of knowledge as well as its application. Ultimately, we seek to foster a responsible relationship between architecture and the natural world, paving the way for a sustainable future that goes beyond mere imitation to encompass true coexistence.

Comparison of Professional Competencies of Students Preparing for the Profession of Preschool and Early Childhood Education Teacher Under Different Forms of Study
Authors: Surma Barbara , Rostek Irmina , Twardowska-Staszek Estera
Published: January 2025

Introduction: The reform of higher education and especially of teaching faculties in recent years has introduced significant changes aimed at improving the quality of professional preparation and acquiring the necessary teaching competencies and qualifications. This article presents the results of a study on the self-assessment of professional competence, conducted among female students of different forms of study .

Research Aim: The purpose of the study was to compare the self-assessment of professional competence of students preparing to practice as a teacher of preschool and early childhood education in different forms of study.

Research Method: The research used the Popular Questionnaire of Emotional Intelligence (PKIE), the PROKOS Questionnaire, the Self-Evaluation of Teaching Competencies survey questionnaire and general survey questionnaire.

Results: The study of female students, graduating in pedagogy and preschool and early childhood education, showed no statistically significant differences in soft skills: emotional intelligence and social competence. Statistically significant differences occurred only in two cases in self-assessment of teaching competencies (cooperation with parents and knowledge of the field of mathematics teaching).

Conclusions: In order to reduce the differences in the assessment of competencies in science subjects, it is necessary to involve students/teachers more in non-formal further education activities, as well as in the framework of internships to take into account the need to develop the competence of cooperation with families, especially with full-time students.
