Frontoparietal Brain Network Plays a Crucial Role in Working Memory Capacity during Complex Cognitive Task
Authors: Otstavnov Nikita , Nieto-Doval Carlos , Galli Giulia , Feurra Matteo
Published: July 2024

Recent neurophysiological studies provide inconsistent results of frontoparietal network (FPN) stimulation for altering working memory (WM) capacity. This study aimed to boost WM capacity by manipulating the activity of the FPN via dual-site high–definition transcranial direct current stimulation. Forty-eight participants were randomly assigned to three stimulation groups, receiving either simultaneous anodal stimulation of the frontal and parietal areas (double stimulation), or stimulation of the frontal area only (single stimulation), or the placebo stimulation (sham) to frontal and parietal areas. After the stimulation, we used an operation span task to test memory accuracy, mathematical accuracy, time of calculation and memorizing, and recall response time across the three groups. The results revealed an enhancement of memory accuracy and a reduction of time of calculation in the double stimulation group compared with that in others. In addition, recall response time was significantly decreased in the double and single stimulation groups compared with that in sham. No differences in mathematical accuracy were observed. Our results confirm the pivotal role of the FPN in WM and suggest its functional dissociation, with the frontal component more implicated in the retrieval stage and the parietal component in the processing and retention stages.
Evaluation of environmental assets value on Borneo using the travel cost method
Authors: Prochazka Petr , Abrham Josef
Published: July 2024

Rainforests, as invaluable natural resources, play a pivotal role globally, offering many ecosystem services such as recreation. This study aims to quantify the value of Brunei’s rainforest assets (specifically recreational areas and national parks) utilizing the Travel Cost Method (TCM), a prevalent approach for ascertaining the worth of natural sites. The tourism use of Brunei’s rainforests holds a high value, estimated at over $300,000 USD per square kilometer, which supports the argument for resource allocation towards their protection not only for ecological reasons but also for their recreational benefits. The authors posit that nature-based ecotourism can be a sustainable and protective mechanism for tropical rainforests. Practical recommendations for ecotourism include a minimalist approach to visitor regulation, limiting access to a small percentage of large recreational areas and national parks to protect flora and fauna, and possibly implementing entry or service fees.

THE TRAGEDY OF NATIONAL HISTORY AND WAYS TO OVERCOME IT IN IVAN TURGENEV’S “A NEST OF GENTRY”
Authors: Belyaeva Irina
Published: July 2024

The article deals with Turgenev’s novel “A Nest of Gentry” and features of the artistic interpretation of tragic collisions in it. It is traditionally believed that the structure of the conflict in the writer’s novels is determined by a principle that goes back to ancient tragedy and that it was fully realized in “A Nest of Gentry.” The conviction in the tragic nature of the writer’s novels is also reinforced by the philosophical foundation of Turgenev, who gravitated toward a tragic understanding of being. The sharp transition from happiness to unhappiness, accompanied by the suffering of the characters and the inevitable state of “tragic balance” in this situation, extended, as is commonly believed, both to the private and to the socio-historical spheres of the novel. As a result, “A Nest of Gentry” has a reputation as a work that testifies to the death of Russian nobility, the unproductiveness of the old ideals of the Lavretsky generation and the dubiousness of the new truth that the hero finds in the ethics of Lisa Kalitina. The author of the article proposes to look at the tragic moods of “A Nest of Gentry” in a different way: through the prism of the perception of the novel by the first readers and critics, as well as in the light of the plot-compositional and ideological role played by the minor character Mikhalevich in it. Particular attention is paid to the XXV chapter of the novel, when Mikhalevich suddenly and, from the plot-compositional point of view, somewhat unmotivated (artificially) appears in front of Lavretsky and tells him that he remained the same (i.e., devoted to the ideals of youth), and acquired a new meaning life through faith in God. As a result, the paper proposes a different interpretation of the social program of the nobility proposed by Turgenev in the novel, and “A Nest of Gentry” is regarded as a text in which the tragic processes inherent in both ordinary life and national history are reflected by the writer in terms of possible rehabilitation and reconciliation, elegiac and dramatic. Turgenev offers his way out of the tragically uncompromising dead ends of social and national life, his social program, which would allow the nobility to change, but not lose their identity.
Analysis of the electroslag technologies usage for steel shavings recycling
Authors: Veretilnyk O.V. , Bікtаgіrоv F.К.
Published: July 2024

The article is devoted to the problem of steel shavings processing. It is shown that electroslag melting has high refining capabilities for obtaining high-quality metal from highly contaminated chips. The peculiarities of various methods of electroslag melting of non-compact charge are considered. The prospect of non-briquetted shavings processing by the method of electroslag crucible melting (ESCM) was noted. When melting high-carbon steel, it is possible to use a non-consumable graphite electrode as a current conductor. When processing low- and medium-carbon steels and alloys, it is necessary to use a metal consumable electrode of the same grade of metal as the shavings as a current conductor. Research and experiments on joint melting of shavings and a consumable electrode made of heat-resistant alloys CrNi70WMoTiAlV, CrNi75MoNbTiAl and stainless steel Cr18Ni10Ti in an electric slag crucible furnace with a capacity of 120 kg were carried out. With the amount of shavings fed to the melting, 50-55 % of the total mass of the metal being remelted, and the furnace being fully loaded, the specific electricity consumption was from 0.48 to 0.55 kWh/kg, and the productivity was from 141.4 up to 170.5 kg/h. The content of alloying elements in heat-resistant alloys and stainless steel due to the adjustment of the slag composition and the possibility of doping while melting was within the standard composition for these metals. The high quality of the metal obtained from waste by the ESCM method is confirmed by the data of mechanical tests of the metal plates with a thickness of 65 and 80 mm made of Cr18Ni10Ti steel, which by all indicators exceed the requirements of the technical conditions for similar cast blanks. The performed analysis shows the prospects of using electroslag crucible melting for recycling steel shavings.

Дослідження присвячене впливу напруження пари на початок конвекції в пористому матеріалі, орієнтованому горизонтально. Цей шар містить хімічно реактивну феромагнітну рідину і зазнає придонного нагріву. У дослідженні використовується метод малих збурень для вивчення і розуміння впливу напруження пари на початок конвекції в цій специфічній системі. З припущенням про неавтокаталітичну екзотермічну реакцію, власні значення визначаються за допомогою методу Ґалеркіна. Проаналізовано вплив параметрів магнітних і парних напружень, а також числа Франка-Каменецького. Спостереження показують, що на прискорення початку фероконвекції впливають як магнітні сили, так і хімічні взаємодії. Водночас наявність парної компоненти напружень сприяє стабілізації системи. Причому, коли нелінійність намагніченості достатньо виражена, дестабілізація шару рідини спостерігається незначною.

Anxiety is a common issue among university students, many of them experience anxiety, depression, and stress during their school life. This study aimed to compare the acute physiological stress responses of students divided into two groups according to their perceived anxiety levels (positive test anxiety, PTA+, and negative test anxiety, PTA-). Heart rate variability (HRV) and electrodermal activity (EDA) were used to assess stress.

Thirty-one healthy volunteers participated in the study. Participants completed anxiety assessments, including the Westside Test Anxiety Scale (WTAS), the State-Trait Anxiety Inventory (STAI), and the Test State Anxiety Inventory (TSAI). Based on their scores, participants were categorized into PTA+ and PTA- groups. All participants underwent 24-h continuous recordings of pulse and electrodermal activity (EDA) on two separate occasions: one day prior to a written exam and during a designated exam-free day serving as a baseline control.

We compared the HRV and EDA data obtained on a regular day and on an exam day between the two groups. Results showed that the PTA+ group had significantly higher heart rate, stress index, low frequency, and short-term detrended fluctuation analysis (DFAα1) on the exam day. The tonic EDA component was also higher in the PTA+ group. Stress-related HRV and EDA parameters were negatively correlated with exam scores.

In conclusion, the study found that physiological stress indicators obtained from HRV and EDA are associated with perceived exam anxiety in students.

Cordyceps militaris, Chinese traditional medicinal fungus, has many bioactive properties. Cordycepin (3'-deoxyadenosine) is a major bioactive component of C. militaris. Various methods can significantly elevate cordycepin production, which suggests a diverse set of metabolic regulatory mechanisms. Thus, we aimed to identify transcription factors that regulate cordycepin biosynthesis pathways. Transcriptome analysis of wild-type C. militaris, C. militaris GYS60, a cordycepin high-producing strain, and C. militaris GYS80, a low-producing strain, were used to measure expression and function of genes related to cordycepin biosynthesis. The transcriptome expression data were confirmed by quantitative real-time polymerase chain reaction. We identified 155 relevant transcription factors in 19 families that included Fork head/winged helix factors, other C4 zinc finger-type factors, C2H2 zinc finger factors, tryptophan cluster factors, nuclear receptors with C4 zinc fingers, homeodomain factors, and Rel homology region factors. Energy generation and amino acid conversion pathways were activated in GYS60 so that abundance of cordycepin precursors was increased. Genes and transcription factors for rate-limiting enzymes in these pathways were identified. Overexpression of two key transcription factors, Kruppel-like factor 4 (Klf4) and Retinoid X receptor alpha (Rxra), promoted high cordycepin production in GYS60. In GYS60, Klf4 and Rxra were responsible for upregulation of genes in cordycepin biosynthesis, namely an oxidoreductase, 3',5'-cyclic AMP phosphodiesterase, a transferase, and adenylate cyclase. Upregulation of these genes increased 3'-AMP content, thereby elevating cordycepin synthesis.

Published: July 2024

Over the past two decades, there has been an increase in the popularity of procedures using hyaluronic acid-based products. In parallel with this, the number of drugs with insufficiently purified hyaluronic acid is growing, in order to reduce the cost of the product, which leads to the development of unwanted adverse reactions (ADRs). The pathogenesis of some reactions is not fully understood, which makes their diagnosis and treatment difficult. The article discusses the types of NPD, factors influencing their development, as well as options for their correction.

Clinical and instrumental data of patients with acute myocardial infarction are of little informative value for COVID-19 identification. The aim is to study the significance of myocardial injury markers on admission in patients with acute myocardial infarction on COVID-19 background. At admission to the hospital in 20 patients with acute myocardial infarction and COVID-19 in blood markers of myocardial damage (highly sensitive troponin T, myoglobin and creatine kinase MB fraction) were studied using immunochemiluminescent method on immunoenzyme analyzer “Cobas e 411” (“Roche Diagnostics”, Germany). The values of highly sensitive troponin T in patients with acute myocardial infarction and COVID-19 were significantly lower than in patients with acute myocardial infarction without COVID-19 (94.8 vs. 171.8 pg/ml). There were no statistically significant differences in the values of myoglobin and the MB creatine kinase fraction in the study groups. Thus, markers of myocardial damage in patients with acute myocardial infarction have no predictive value in relation to COVID-19.

La labor terapéutica: entre las narrativas y la intimidad
Authors: Osorio Sánchez Yeny Leydy
Published: July 2024

Este ensayo presenta la narratividad como una construcción de la propia historia personal, y como una manera de construir, reconstruir y entregar la historia personal durante el proceso psicoterapéutico. Por otro lado, se aborda el concepto de intimidad, desde la propuesta teórica de José Luis Pardo, para proponer que no sólo se trabaja con las narrativas de la propia existencia, sino, además, con lo que escapa a ellas, con lo que no es alcanzado por la palabra, con lo íntimo. El abordaje de la intimidad es uno de los fundamentos del trabajo terapéutico.

La discriminación social desde una perspectiva psicosociológica
Authors: Navarro Carrascal Oscar , Prevert Alina , Bogalska-Martin Ewa
Published: July 2024

La discriminación social inquieta a los organismos públicos en Europa ya que debilita el tejido y la cohesión social. Este fenómeno puede ser abordado desde dos lecturas; la perspectiva psicosocial, en que se destacan los mecanismos cognitivos que nos permiten comprender y relacionarnos con el mundo y sus objetos; y una perspectiva macrosocial que permite dar cuenta de las estructuras sociales e ideológicas que sustentan esos mecanismos. Dos estudios empíricos apoyan esta investigación. Por un lado un análisis comparativo Francia-Polonia donde se examina la representación social de la discriminación. Por otro lado, en el contexto francés, un estudio sobre las reclamaciones de víctimas de discriminación realizadas a tres diferentes organizaciones que luchan contra la discriminación: un ente estatal (la HALDE), una ONG (SOS Racisme), y un sindicato (la CGT).

Diffuse leptomeningeal glioneuronal tumor was introduced into the World Health Organization classification of central nervous system tumors in 2016. According to the actual World Health Organization classification of central nervous system tumors emerged in 2021, its reliable verification requires the combination of specific pathomorphological and molecular-genetic features as well as data of the neuroimaging. Typically occurring in children and adolescents these tumors are characterized by widespread diffuse leptomeningeal dissemination along the neuraxis and demonstrate a tendency to abundant contrast enhancement resulting in a specific magnetic resonance imaging appearance. Despite this, and the rather rare incidence, a number of publications have reported an increasing number of atypical cases of diffuse leptomeningeal glioneuronal tumor suggesting that the spectrum of clinical manifestations, molecular-genetic and radiological criteria of this tumor is not fully disclosed and requiring further comprehensive investigations. The article presents the experience of complex, interdisciplinary diagnosis of diffuse leptomeningeal glioneuronal tumor with atypical radiological picture in a child with focal structural epilepsy.

Changes in the Content and Structure of Students' Life Projects in the Educational Reflexive Dialogue
Authors: Logutenkova I.V.
Published: July 2024

This article discusses the problem of developing new teaching methods that are based on the use of reflexive technologies. One of the key components of these technologies is systemic reflection as a condition for the realization of personal potential. The paper contains a brief overview of theoretical, methodological and applied developments in the field of studying the phenomenon of reflection in Russian psychological science, which serve as a theoretical basis for the development of reflexology. The main conditions of the organization of reflexive dialogue, the principles of its construction, the necessary structural components and a summary of the author's development - the reflexive training "Life project of the individual" are described. The author's development - refletrening "Life project of personality" contains a description of the basic conditions of its organization, the principles of construction and the necessary structural components. The results of an empirical study of the influence of educational reflexive dialogue on the formation of students' life projects are presented. The use of reflexive practices (reflexive training) in reflexive dialogue for building life projects in adolescents is also justified. It has been empirically established that changes in the structure and content of life projects are noted equally in all subjects, regardless of their personal characteristics, but more likely in students with high scores on such personal characteristics as orientation in time (understanding the existential value of life), creative attitude to life (creativity), autosympathy, contact, systemic reflection", volitional regulation of behavior (control-naturalness), the level of general reflexivity, the appropriation of socially significant roles, the availability of experiences, openness to new experiences and self-assessment of metacognitive activity.
ASSESSING PHYSICAL LITERACY OF PRE-SCHOOL CHILDREN – A SYSTEMATIC LITERATURE REVIEW
Authors: Kretaine Agnese , Vecenane Helena
Published: July 2024

In recent years, it has become topical to study the concept of physical literacy in early childhood, based on empirical evidence of how the formation of skills takes place at this stage. The question remains open for the researchers - how to standardize and simply assess the physical literacy given its broad framework. One of the definitions of physical literacy explains the essence and importance of this concept in a person's life as internal motivation, confidence, competence in physical activities, knowledge and the person's own responsibility for applying it in practice. The systematic literature review was conducted with the aim of identifying a safe, sustainable and easy-to-apply physical literacy assessment tool for preschool children aged 3 to 7 years.
Methodology. The systematic literature review protocol includes sources from such databases as EBSCO host (MEDLINE, Eric), Google Scholar, Science Direct, ERIH PLUS, Scopus and Web of Science for the period 2018 – 2024, which title, summary and keywords meets the certain criteria and content includes information on physical literacy assessment tools for the age specified. The content analysis was performed for the identified tools to find out their relevance for the assessment of physical, affective, cognitive, and participatory domains of physical literacy.
Results. As a result of the content analysis, 26 different tools for assessing physical literacy in pre-school age were identified.

Published: July 2024

Although Pinus sylvestris has a wide distribution throughout Europe, there are lack of scientifically approved information related to the sapwood timber strength parameters impregnated with natural resins comparing to the strenth parameters of non-resinous wood and industrially impregnated roundwood assortments using as the elements of wooden constructions such as wood poles for power lines. The main goal of the study is to work out the Pinus sylvestris stems  which were previously treated using resin tapping technologies and  harvested in final felling sites, timber strength parameters depending on timber quality characterized data based on the testing methods: moisture content - according to ISO13061-1:2014; density - according to ISO13061-2:2014; compression strength paralel to the grain- according to ISO 13061-17:2017; modulus of elasticity- according to ISO 13061- 4:2014; three point bending strength - according to ISO 13061- 3:2014. The results of the study might help for practical applications so that this wood specie can be processed more efficiently for the value - added products whose timber quality indicators would allow it to be used in wooden structures without additional chemical and thermal treatment, to establish more accurate quality requirements for roundwood assortments and to provide useful information for optimizing Scots pine harvesting management programs.

Sustainability reporting plays a crucial role in promoting ethical conduct, managing risks, and enhancing stakeholder engagement for businesses aiming for long-term success. Recent changes in European legislation, particularly the Corporate Sustainability Reporting Directive (CSRD), signal a significant shift towards aligning sustainability reporting with financial reporting to meet Sustainable Development Goals. Concurrently, advancements in Environmental, Social, and Governance (ESG) reporting processes have led to the emergence of tech-based platforms, leveraging artificial intelligence (AI), to streamline data gathering and compliance efforts among EU companies. This paper examines the potential impacts of such platforms, focusing on their role in facilitating ESG information collection for regulatory compliance. Utilizing secondary sources such as European legislative acts and relevant literature, the study also presents a case study of "Ecomate ESG platform" as an illustrative example. In addition to regulatory compliance, these platforms offer benefits such as improved efficiency and enhanced stakeholder engagement. The conclusion draws upon key findings to propose general recommendations for the future development of the ESG sector and the effective utilization of AI within it.;

The article's research focus is to investigate the impact of technologies used in smart cities to achieve environmental sustainability. The research methods used to review scientific studies worldwide on the problem under consideration, analysis and synthesis, comparative analysis, and logical approach. The information and communication technologies in smart cities aim to promote sustainability and provide adequate services to citizens, thereby improving their quality of life. Specific characteristics of smart cities are the extensive use of technology, real-time monitoring, innovation, and citizen empowerment, with a constant focus on sustainability. Analysis of the cited examples shows that technologies are being deployed in smart cities to improve transportation systems, deal with traffic jams and waiting times at traffic lights, and more with real-time data analysis. In most examples, information and communication technologies create a smart grid to achieve optimal energy use and improve the efficiency, reliability, and economy of the provided utility services. Self-monitoring and control of smart grids are realized using intelligent sensors and smart meters for energy transmission and distribution for real-time analysis of current consumption. An intelligent energy system involves using technologies for efficient energy production and distribution. The conducted case study on the effectiveness of the smart city in terms of environmental sustainability establishes that the sustainable management of resources and reducing the harmful impact on climate change and the environment requires optimizing the use of energy and resources and increasing the use of renewable energy sources. Analysis shows how technology can achieve environmental sustainability by reducing carbon emissions from cities, improving air quality, and optimizing the use of natural resources. Implementing intelligent systems and applications can reduce greenhouse gas emissions by an average of 20%, water consumption by up to 30%, and the amount of non-recyclable solid waste by around 15-20%, depending on the city's specific characteristics.
