European standards for the organization and implementation of scientific research and their legal support in Ukraine
Authors: Parkhomenko N.
Published: February 2025

The article is devoted to the definition of European standards for the organization and implementation of scientific research and the legal basis for their implementation in Ukraine in the aspect of Ukraine’s integration into the European Research Area. Among the basic principles of the organization and functioning of the European Research Area (USR): openness and interaction between scientists, research, scientific institutions; a unified system of regulations and standards for scientific research; career development as an opportunity to improve working conditions for researchers, to ensure their socio-economic support; interethnic cooperation. The basic principles of open science as the storage, management and exchange of research data must comply with FAIR guidelines: accessibility, interaction, reusability. The legal basis for ensuring these principles are determined by the laws of Ukraine «On Scientific and Scientific-Technical Activities» and «On Cloud Services,» as well as a number of by-laws, which are mainly conceptual in nature.
It is emphasized that in the context of the ongoing war, it is extremely difficult to implement in full the mechanisms for ensuring European standards in the field of scientific research, especially in terms of career development as an opportunity to improve working conditions for researchers. In the aspect of introducing and maintaining a unified system of regulations and standards for scientific research throughout Europe, it is important to ensure the coordinated actions of all authorized and interested entities in the scientific, educational spheres and their close connection with the production sector. In this connection, it is necessary to create conditions for the emergence of demand for innovative technologies.
Compliance with the organization and implementation of scientific research also requires a modern management system in the field of science, capable of developing domestic and foreign (international, including European) legal policy in the distant and near future, to carry out systemic and predictive influence on the development of science in its interdisciplinary and intersectoral diversity, and relevant social relations.
Public order as a legal category: doctrinal analysis
Authors: Ruschak I. V.
Published: February 2025

Modern legal doctrine considers public order as a multifaceted legal construct that integrates key principles of law and order, ethical norms of society and basic legal values.
The article examines the institution of public order as a complex legal phenomenon in the civil law system of Ukraine. Based on the analysis of scientific sources and legislation, the essence and content of the category of public order, its features and significance for the legal system are revealed. Special attention is paid to the study of public order in the context of the invalidity of transactions and private international law. The problem of determining the content of public order in judicial practice and doctrine, its correlation with the norms of civil law are analyzed. Theoretical and practical problems of applying the category of public order as a basis for the invalidity of transactions are considered. The historical development of the concept of public order from Roman law to the present day, its transformation in the Soviet period and the peculiarities of understanding in the conditions of a market economy are investigated.
Special attention is paid to the analysis of public order as a mechanism for restricting the application of foreign law in private international law. The approaches to the definition of public order in the legislation and judicial practice of Ukraine are analyzed, in particular, some positions of the Supreme Court of Ukraine on the interpretation of this category. The issues of the correlation of public and private law in the context of public order are studied, as well as the features of its application in different legal systems. The specifics of the application of the category of public order in international commercial arbitration and in the recognition and enforcement of foreign court decisions are considered. Based on the conducted research, the need for a clear legislative definition of the category of public order and improvement of the mechanisms of its application in judicial practice is substantiated. The conclusion is made about the dual nature of public order in civil law and its importance for protecting the fundamental interests of society and the state. Ways of improving the legal regulation of public order are proposed, taking into account international experience and modern trends in the development of law.
The content of the legal mechanism for ensuring the social security of the state
Authors: Belousov V. D.
Published: February 2025

The article explores the essential content of the legal mechanism for ensuring social security in modern Ukraine. It establishes that this mechanism consists of elements consistent with legal principles – specifically, the forms, methods, and means provided by current legislation to ensure social security. It also encompasses processes and relationships through which the actors responsible for social security plan, create, protect, defend, and restore conditions to either eliminate social risks or, where elimination is not feasible, provide compensation. The author argues that this legal mechanism exhibits several unique characteristics. First, it has a clear systemic and organisational nature, based on the general social and related policies of the state. Second, it operates on the principle of combining general norms of social legislation with specific norms of administrative legislation. Third, it considers the specific real and potential social risks and challenges to the state’s social security, with applicability to the entire population. Fourth, it enables a system of actors responsible for ensuring the state’s social security. The article indicates that the legal mechanism for ensuring social security, as a distinct legal structure, constitutes a complex system of elements. The key components of this system are, first, the principles for ensuring the state’s social security. Second, an important component is the set of current legislative norms that regulate various aspects of social security. Third, an essential component consists of the actors of social security – both collective and individual legal entities. These actors, in accordance with their legal status and the principles of social solidarity and responsibility, plan, organise, and implement activities aimed at preventing and minimising social threats. They work to stabilise and develop society in response to internal and external challenges affecting the state’s level of social security. The article concludes by summarising the findings of the research.
Organizational structure of the notary office and principles of its structure
Authors: Solotskyi D. O.
Published: February 2025

The article is devoted to the study of the organizational structure of the notary public and the principles of its construction. In this context, it is noted that the organizational structure of the notary public reflects the competence and system of notarial bodies and officials authorized to carry out notarial activities. It is established that the organizational system of the notary public, depending on the legal status of its subjects and the presence of their powers regarding notarial activities, includes: 1) general subjects who can perform any notarial actions - a) notaries, who can be both state and private; b) authorized officials involved in notarial activities due to a territorial feature (those located outside the territory of Ukraine or in the territory of rural settlements); 2) special subjects who can perform certain notarial actions in cases specified by law - authorized officials involved in notarial activities due to a local feature.
Attention is focused on the fact that the organizational system for building a notary public is based, first of all, on the principles of comprehensiveness and territorial-local accessibility. The impact of these principles on the activities of all entities that carry out notarial activities in full or perform individual notarial actions, regardless of their stay in the territory of Ukraine or outside it, is analyzed. It is noted that the introduction of the martial law legal regime in Ukraine mediated the need for mandatory consideration of the legislation on sanctions, which is manifested in the implementation of additional control during the acceptance of documents by diplomatic and consular institutions regarding the status of persons who have applied and their compliance with the legislation on the legal regime of martial law.
The derived principles of the organization of notarial services are identified, namely: the performance of notarial acts and actions equivalent to them only by authorized persons; the possibility of appealing against the performed notarial acts or refusal to perform them; the obligation to be subordinate to the Ministry of Justice of Ukraine regardless of the position of the official performing the notarial act or the action equivalent to it in the notarial system or the place of performance of the notarial act; the obligation to register notarial acts and actions equivalent to them regardless of the position of the official performing the notarial act in the notarial system or the place of performance of the notarial act, etc.
Forensic characteristics of criminal offenses: concepts, signs and related legal constructions
Authors: Yermak O. V.
Published: February 2025

The proposed article provides a detailed consideration of the issues that arise in the course of the search for interdisciplinary connections of criminology with criminal, criminal procedural, criminal executive law, the theory of operational investigative activity, administrative tort law, as well as with criminology and the psychology of criminal activity. The researcher draws attention to the fact that to date there is no unified position of the authors regarding the definition of the concept and meaningful content of the essential features of any of the above-mentioned characteristics associated with such a fundamental phenomenon (process), which is a criminal offense in the form of a crime or a criminal misdemeanor . The author proves that the further scientific filling of forensic characteristics as one of the central categories of modern criminology, as well as other related branch characteristics (criminal- legal, criminal procedural, criminological, operational-investigative characteristics, psychological-legal, administrative-tort, etc.) is expedient to be carried out using modern methodology, i.e. a set of tools (methods) chosen by the researcher, as well as necessarily taking into account the meaning of officially recognized normative legal acts of higher legal force (defined in the Criminal Code, Criminal Executive Code, the Code of Ukraine on Administrative Offenses and the Criminal Code procedural codes of Ukraine), terminology, including the concept of «criminal offense». At the same time, it is stated that in the majority of modern educational literature on criminology and publications in this field, criminologists attach legal cognitive characteristics only to the outdated concept of crime, forgetting about the second form of criminal offense - criminal misdemeanor, defining the concept and its main features, resorting to the use of the phrase «forensic characteristics of the crime», but it should be used - «forensic characteristics of the criminal offense». The author objects to the groundless limitation of the subject of study of the sciences of the criminal-legal cycle by using only the old term «crime», neglecting its logical connections with such categories as «criminal offense» and its second form - «criminal misdemeanor».

Published: February 2025

As technology advances and 21st-century skills become increasingly essential, innovative learning methods are crucial for developing students' problem-solving skills (PSS). This research evaluates the PSS profile of high school students in physics by integrating augmented reality (AR) media with a problem-based learning (PBL) model, aligned with SDG 4 (quality education). Using a preliminary qualitative descriptive analysis, data were collected through PSS tests, interviews, and questionnaires. The results reveal that PSS remains underdeveloped: 95 students were categorized as low, 26 as medium, and only 1 as high. Despite understanding the problems, students struggle to provide answers and review solutions, largely due to a lack of independent problem-solving practice. Additionally, the use of technology in schools must be improved. Intensive practice and effective learning models are essential. The implementation of AR technology can enhance learning engagement and outcomes. This study underscores the importance of integrating technology to improve PSS and motivate students, supporting inclusive and quality education as outlined in SDG 4

Authors: Silva Mariana Cavalcante da , Gomes Heliofábio Barros , Silva Fabrício Daniel dos Santos , Mariano Glauber Lopes , Santos Jannaylton Everton Oliveira , Accioly Joao Otavio Alves
Published: February 2025

Objective: to present the results of a climatological analysis of evapotranspiration (ET) in the Brazilian Northeast (NEB) between 1961 and 2020, highlighting its seasonality, the identification of homogeneous groups by cluster analysis, and positive trends over the decades. In addition, the text compares the accuracy of two datasets (MODGroETa and ERA5-Land), emphasizing the superiority of ERA5-Land for ET estimates, especially after bias correction. The central purpose is to highlight the relevance of continuously monitoring and evaluating ET data for different regions and time scales.
 
Method: For this study, meteorological data from the National Institute of Meteorology (INMET) and high-resolution gridded analyses (0.1° x 0.1°) adjusted by elevation were used. These data underwent rigorous quality control and altitude correction. It used atmospheric reanalysis data with high spatial resolution (9 km) and hourly temporal frequency, based on observations from satellites, surface stations and snow data. The remote sensing model derived from MOD16 was used to estimate evapotranspiration (ET) based on the Penman-Monteith equation. It is available with a spatial resolution of 0.1° and a decadal time scale. Multivariate statistical technique applied to identify homogeneous areas in Northeast Brazil with similar ET characteristics, based on the monthly distribution of data.
 
Results and Discussion: The climatology of ET (1961-2020) in the NEB showed strong seasonality. Between January and April, the highest values (>4 mm/day) are concentrated in the semi-arid region, decreasing in the west of Piauí and Maranhão (<3.5 mm/day). From May to July, ET decreases in the east, while from September to December, the interior registers maximums (>5.5 mm/day). Cluster analysis identified six homogeneous regions, independent of rainfall patterns, with higher ET from September to November and lower values between April and June, showing significant seasonal variations in the NEB.
 
Research implications: The research contributes to water management, agricultural zoning and environmental conservation in the Brazilian Northeast (NEB). It identifies trends in evapotranspiration (ET) associated with climate change, provides subsidies for improving climate models and public policies, and fosters future research into adaptation and mitigation of impacts on ecosystems and communities.
 
Originality/Value: The study is original in identifying regional patterns of evapotranspiration in the NEB, combining cluster analysis and multiple data sources. Its value lies in its practical application for water management, agricultural zoning, environmental conservation and public policies, strengthening climate adaptation strategies and mitigating impacts on vulnerable ecosystems and communities.

Navigating through the diagnostic labyrinth of rare bifocal intracranial germ cell tumors: A case report
Authors: Parvin Hena , Dutta Anwesha , Hazra Subhrajit
Published: February 2025

Background: Intracranial germ cell tumors (iGCTs) are a rare and heterogeneous group of neoplasms originating from germ cells within the central nervous system (CNS). These tumors are a subclass of CNS germ cell tumors (GCTs) that are typically observed in 1st to 2nd decades of life. They tend to occur in the midline, either at the pineal region or along the floor of the third ventricle/suprasellar region. Less commonly, both regions can be involved, presenting as bifocal tumors which usually carry a worse prognosis. Such bifocal lesions can be either two independent primary germinomas (GEs) (known as true bifocal GE) or it can be one primary GE with metastases (known as false bifocal GE). Bifocal presentation is mostly seen in GE, but some of the patients may have mixed GCT. Clinical features are mainly due to the mass effect and involvement of sellar and supra-sellar regions.
Case Presentation: A 21-year-old male presented with complaints of erectile dysfunction, lack of libido, headache, polydipsia,
polyuria, diplopia, and recent onset blurring of vision over the past 6 months to 1 year. Radiological investigations revealed
the presence of true bifocal iGCTs, which were confirmed to be β-human chorionic gonadotropin producing GEs upon
histopathological and immunohistochemical analysis. The patient showed complete resolution of the tumor following treatment.
Conclusion: Intracranial GEs are highly radiosensitive tumors often characterized by insidious symptoms, leading to a significant delay in diagnosis, with patients often seeking medical assistance only when their daily activities are severely impaired. However, this delay could be mitigated by obtaining a thorough patient history and maintaining a high index of suspicion for intracranial GEs, particularly in the appropriate age groups. Our case report emphasizes the importance of a multidisciplinary team approach in facilitating timely and informed decision-making for optimal patient management.

Authors: Kitwatthanachai Issariya , Silpa-archa Narumol
Published: February 2025

Background: Mycoplasma pneumoniae (M. pneumoniae) is one of the most common causes of atypical pneumonia in
pediatric and adult populations worldwide. It can also affect many other organs including neurological, cardiac, hematologic,
gastrointestinal, renal, osteoarticular, ocular, and cutaneous involvement. Mycoplasma pneumoniae-related cutaneous vasculitis is an infrequent manifestation. Several cases of secondary cutaneous leukocytoclastic vasculitis (LCV) associated with M. pneumoniae have been publicly reported in both English and foreign languages.
Case Presentation: This report details the case of a 44-year-old Thai male presented with high-grade fever accompanied by
generalized erythematous papules, patches, and some pustules for 3 days with no chest symptoms. He was treated with
ceftriaxone, doxycycline, and clindamycin for 5 days without clinical improvement. However, histopathological and direct
immunofluorescence tests later confirmed a diagnosis of LCV. Serological tests showed positivity for M. pneumoniae. The
regimen was then changed to azithromycin 500 mg daily for 5 days and the lesions showed remarked improvement without
scarring.
Conclusion: The importance of recognizing and addressing the atypical presentations of M. pneumoniae in febrile patients with cutaneous vasculitis is imperative to guide targeted treatment decisions, thus facilitating rapid clinical improvement.

Authors: Jamjoom Maan , Altirkistani Bsaim Abdulsalam , Qashqari Abdulaziz
Published: February 2025

Background: Kidney transplantation is the preferred treatment for end-stage renal disease (ESRD) due to its superior outcomes compared to dialysis. However, complications such as infection, wound dehiscence, incisional hernia (IH), and rarely, renal paratransplant hernia (RPH) can occur post-transplant. This study reported a case of a patient with a post-renal transplant who presented abdominal symptoms requiring urgent laparotomy for an obstructed hernia at the transplant site.
Case Presentation: A 57-year-old male with non-alcoholic fatty liver disease, ESRD secondary to IgA nephropathy, myelofibrosis, and renal stones underwent a renal transplant from his son. He presented to the emergency department 6 days after he was discharged with severe abdominal pain, vomiting, and a visible bulge at the transplant incision. Ultrasound confirmed an IH with small bowel obstruction. Exploratory laparotomy successfully managed the hernia, and postoperative care included antibiotics and supportive measures. The patient recovered uneventfully and was discharged in good condition.
Conclusion: RPH represents a significant but uncommon complication following kidney transplantation. Timely identification and surgical intervention are essential for favorable outcomes. Despite the immunosuppressive risks, the incidence of RPH remains relatively low. Careful surgical planning is crucial to mitigate complications, and ongoing research is needed to refine treatment strategies, particularly exploring laparoscopic approaches in select cases.

O presente estudo teve como objetivo analisar a dinâmica produtiva e a participação da agricultura familiar na suinocultura nordestina, por meio dos Censos Agropecuários 2006 e 2017. Para isso, foram reunidos dados secundários obtidos por meio do IBGE e analisados por estatística descritiva. Para fomentar as discussões, utilizou-se de revisão bibliográfica e documental. Os resultados mostraram que, apesar do Nordeste liderar o número de estabelecimentos com suínos, o efetivo animal é pequeno, sugerindo o foco no autoconsumo. Também foi possível observar que houve uma diminuição do número de estabelecimentos da agricultura familiar, devido à limitação territorial, comerciais e de acesso a tecnologias. Nesse sentido, conclui-se que a suinocultura nordestina é heterogênea entre os estados, porém a tendência ao autoconsumo se mantém. Além disso, afirma-se que o acesso a tecnologias e mercados ainda é dominado pela suinocultura industrial, que nem sempre está em estabelecimentos de agricultura familiar.

Blunt-body entry vehicles induce complex flow phenomena that result in dynamic instabilities in the low supersonic to transonic flight regime. Dynamic stability coefficients are typically calculated through parameter identification and trajectory regression techniques using both physical test data and computational fluid dynamics (CFD) simulations. The objective of this work is to advance the quantification of the dynamic stability behavior of blunt-body entry vehicles by leveraging high-fidelity CFD data through reduced-order modeling (ROM). ROMs are capable of leveraging high-fidelity aerodynamic data in a cost-effective manner by finding a low-dimensional representation of the full-order model. ROMs based on proper orthogonal decomposition have shown success in recreating CFD analyses of parametric ROM applications and time-varying ROM applications. Results of this research demonstrated success in constructing two ROMs of a blunt-body entry vehicle to recreate heatshield and backshell pressure distributions from forced oscillation trajectories. The ROM was more successful at reconstructing the heatshield pressure distribution, with challenges arising in predicting the chaotic response of backshell latent coordinates.

A direct connect, optically accessible combustor was used to reveal flow characteristics inside a reacting solid fuel supersonic combustor with air inlet total pressure of 12.9 atm and total temperature of 1225 K using polymethyl-methacrylate fuel grains. Flow visualization techniques such as shadowgraph, chemiluminescence, and high-speed imaging/planar pyrometry were used to characterize the flowfield, which has not been previously reported on for a solid fuel scramjet. Shadowgraphs revealed the role of the cavity flameholder geometry in defining the flowfield. Large length to depth ratios force the recirculation zone to expand into the core flow, causing flow biasing. Small length to depth ratios allow the recirculation zone to be fully contained within the flameholding cavity. [Formula: see text] chemiluminescence shows that most of the heat release takes place in the cavity flameholder favoring the upstream region near the air inlet. Both the flow visualization and measured fuel regression rates indicate that the majority of the fuel that contributes to combustion pyrolyzes from the converging angle of the flameholding cavity. Fuel regression rates decrease as fuel is consumed and the cross sectional area of the flowpath increases, consistent with historical observation of solid fuel regression rate dependency on air mass flux.

The study highlights the need to accommodate individual preferences and comfort levels in using the TikTok applications for language learning. This study aims to investigate the difficulties students face in performing English conversations and to analyze the students’ perceptions of using the TikTok application to perform English conversations. The present study employed qualitative paradigm using the type of case study and was conducted at one of the vocational schools in Ciamis. Additionally, the researcher used interviews and observation to answer the research objectives. The study discovered that students faced several challenges in creating content. Technical issues, such as video errors and slow upload times, were common obstacles. Additionally, environmental factors, such as background noise, often interfere with the quality of their videos. On a personal level, difficulties with language proficiency and a lack of confidence in content creation further complicated the process. These challenges underscore the importance of providing support and guidance for integrating TikTok as an educational tool effectively. However, the findings showed that TikTok has an appeal as an English language learning medium, particularly in developing speaking skills and boosting student confidence. A highly positive student responds to learning to speak  through the TikTok Application because it fosters enthusiasm, motivation, and comfort in English conversation performance.
