Authors: Борківський Б. П. , Теслюк В. М.
Published: October 2023

Запропоновано вдосконалення нейромережевого методу розпізнавання об'єктів для пошуку доречних об'єктів в межах заданого контексту. Проаналізовано останні дослідження та підходи до вирішення проблеми розпізнавання об'єктів і виявлено ключові особливості декількох архітектур нейронних мереж. Наведено метод, що базується на поєднанні нейронної мережі, пристосованої до пошуку образів, та застосуванні додаткових алгоритмів для вилучення зайвих об'єктів, а саме алгоритму видалення дублікатів об'єктів та алгоритму фільтрації об'єктів відповідно до контексту. Застосовано готову архітектуру Single Shot Detector як основу нейронної мережі для розпізнавання об'єктів, треновану на наборі даних COCO. Розроблено алгоритм фільтрації об'єктів, який містить попереднє створення конфігурації, для визначення множин доречних класів об'єктів для різних контекстів. Розроблено гнучку конфігурацію, яка може бути модифікована та розширена новими умовами роботи, за потреби, без додаткових змін у логіці програмної частини. Проведено низку експериментів для визначення точності роботи системи у нових середовищах, під час яких систему протестовано з використанням набору даних ODSR-IHS, який містить зображення, отримані під час роботи роботів-порохотягів, і досягнуто точності розпізнавання 5 класів об'єктів на рівні 83 %. Виявлено під час проведення експериментів здатність системи знаходити більшу кількість значущих об'єктів, ніж передбачалось авторами набору даних, зокрема людей у кадрі, що свідчить про перспективність використання системи у різному оточенні. Встановлено, що завдяки використанню диверсифікованого набору даних із 80 класами об'єктів та відбором тільки значущих предметів розроблена система є ефективною під час використання у різних середовищах. Запропонований метод вирішує проблему перевикористання єдиної системи розпізнавання об'єктів у різних середовищах, що спрощує її використання у мобільних системах, які можуть працювати у різному оточенні.

Published: October 2023

This dosimetric study analyzed the lateral wedge with medial only cardiac shielding (LEMONADE) technique for left breast radiotherapy (LBRT) against three other commonly used techniques which is a follow-up from our earlier publication of LEMONADE technique in left chest wall (LCW) radiotherapy.

Dosimetric parameters of 30 consecutive patients who underwent LBRT with LEMONADE technique (P1) after breast conserving surgery (BCS) were compared with 3 other virtually reconstructed plans: no cardiac shielding with paired wedges; P2 (paired wedges and medial only Y-direction shielding) and P3 (paired wedges and bilateral Y-direction shielding).

P1 had target volume (TV) coverage [mean 90% isodose coverage of 89.00% ± 3.96 vs 86.28% ± 4.80 and 84.43% ± 5.70 for P2 and P3, respectively]. While there is 3.07% drop in TV coverage compared to no cardiac shielding, the V26Gy of heart dropped from 5.26% to a negligible 0.56% for P1. Low dose region (TV receiving < 30Gy) is also significantly lesser for P1 compared to P2 and P3 (1.50% vs 3.61% and 5.65%).

The earlier positive LEMONADE dosimetric study of LCW radiotherapy has been replicated in this study with much better dose volume parametres likely due to the physical properties of intact breast. LEMONADE is an easily re-producible and simple radiotherapy technique that can be implemented in most radiotherapy centres. Further study is needed on the use of LEMONADE technique in extreme hypofractionation.

Authors: Shalihin Mohd Shaiful Ehsan Bin , NAZURIN MUHAMMAD ZULFAQAR
Published: October 2023

World Health Organization reported that cardiovascular disease (CVD) is the leading cause of death, which has taken approximately 17.9 million lives across the globe. Current studies identified high prevalence and severity of metabolic syndrome in children which is likely increase the incidence of premature death and contribute to the statistical number of cardiovascular disease and related events worldwide. Therefore, measurement of the cardiovascular risk score among the children, specifically adolescent need to be implemented in order to modify the risk and improve the disease outcomes. This review aims to identify the assessment methods and the implications. Full-text article on case control, cohort and cross-sectional studies published from 1st Jan 2012 until 30th September 2022, were searched using PubMed, CINAHL and Scopus. Teenagers or adolescent age range from 11 to 19 years were included in this study. The cardiovascular risk and score assessment methods as well as the outcomes of the assessment were included in this study. 8 out of 40 articles met the eligibility criteria and were selected. Two out of eight studies classify the risk factors into categories. One study classified the participants into high, medium and low risk group while another study categorised them into fit and unfit. Most studies agreed that assessment of CVD risk should focus on multiple risk factors instead of individual risk. Two studies suggest increase physical activities among children can reduce the obesity. Another study recommended family-based intervention to prevent CVD risk factors particularly obesity. In conclusion, predicting CVD from childhood and adolescence required a multifactorial assessment. Majority of study showed that multiple risk assessment is required to predict cardiovascular events and early interventions are needed in children who pose higher risk compared to others

Published: October 2023

One of the cancer treatment modalities is drug combinations. Nonetheless, the combined effect can be equal to, less than, or greater than each drug alone, and an effect greater than either agent alone does not necessarily imply synergism. This study, therefore, evaluated the cytotoxic interaction of temozolomide and doxycycline co-treatment in the human glioblastoma U87 cell line.

Published: October 2023

Objectives: The quarantine due to the COVID-19 pandemic has induced stress among university students. Lifestyle changes during this quarantine period have contributed to changes in eating habits. Thus, this study aimed to determine the factors affecting weight status during the COVID-19 quarantine period among undergraduate students at Universiti Sains Malaysia (USM).

Methods: 114 subjects were recruited in this retrospective cross-sectional study. Sections of the questionnaire were sociodemographic information, anthropometry measurements, Depression, Anxiety, and Stress Scale (DASS), and Binge Eating Scale (BES). Subjects were required to recall this information during the pre-quarantine period in February 2020 and the post-quarantine period in July 2020.

Results: 52.6% of the students had weight gain. The prevalence of overweight and obesity increased from 15.8% and 4.4% before the quarantine to 17.5% and 6.1%, respectively, after the quarantine. Extreme levels of stress, anxiety, and depression were reported by 0.9%, 19.3%, and 8.8% of the respondents. Regression analysis revealed that binge eating score was the only significant predictor of weight status before and after the quarantine period.

Conclusion: Altered eating behaviour during the COVID-19 quarantine contributed to weight changes among university students in Malaysia. Factors influencing eating habits must be identified to reduce the incidence of overweight and obesity among university students, especially during the pandemic.

Agarwood, is a fragrant resinous wood unique due to its peculiarity of being formed and harvested only from diseased trees of certain genus of Thymelaeaceae. It has survived years of history and established itself in the modern agarwood value chain. It is only logical that the progress has been fueled by scientific research carried out over the years. This current review is the first bibliometric study to uncover the agarwood research trend across the many themes. Bibliometric data were extracted from Scopus database in March 2021 using the search term ‘agarwood’ within the year 1959 to 2021. A total of 513 records were analysed using VosViewer and Publish or Perish software. Collectively, the articles were cited 6216 times with citations per year of 100.26 and h-index of 42. The top-contributing countries were China, Malaysia, Japan and Indonesia. Most of the publications were in the area of agricultural and biological sciences; biochemistry, genetics and molecular biology; chemistry; and pharmacology/pharmaceutics. The early years of agarwood research was focused on chemical compounds followed by studies on biological effects before the themes became varied in the last ten years. Critical knowledge gaps identified include safety of agarwood and its related materials, translational link between proof of concept and clinical applications as well as role of agarwood in socioeconomic development of a nation. Altogether, this work could be used as a landscape to chart the future research that leverage agarwood-producing trees as economic plant species towards progressive yet sustainable socioeconomic development and benefit to mankind.
Loss of regulation of T helper 17 cells: a definitive factor for critical cases of coronavirus disease 2019
Authors: Pardiño-Vega Miguel Angel , Herrera-González Norma Estela
Published: October 2023

One of the greatest challenges in the study of coronavirus disease 2019 (COVID-19) has been to establish the determining factors in the severity of the disease. Through extensive research efforts, a crucial factor responsible for disease control or exacerbation in COVID-19 has been identified—the regulation of the immune response. The abnormal release of interleukin-1 (IL-1), IL-6, and tumor necrosis factor-alpha (TNF-α) has been extensively studied in the context of the altered immune response observed in severe cases of COVID-19. However, recent attention has turned towards the excessive release of IL-17 and the increased presence of T helper 17 (Th17) cells, the main secretory cells of this cytokine. These factors have garnered interest due to their potential involvement in the cytokine storm observed in severe cases of COVID-19. In this review, it will be delved into the intricate mechanisms by which IL-6 contributes to the differentiation of Th17 cells, resulting in an increase in the population of Th17 cells. Moreover, it will be explored the proportional relationship between the increase of these lymphocytes and the release of IL-17 and other chemokines, which all together play a key role in promoting the chemotaxis and activation of neutrophils. Ultimately, this cascade of events culminates in the generation of tissue damage by neutrophils. Additionally, therapeutic options targeting these lymphocytes and cytokines are explored, providing insights into potential avenues for intervention.

Published: October 2023

The receiver operating characteristic (ROC) curve is a well-known graphical method to describe the accuracy of a diagnostic test. In this paper, Logistic kernel is proposed with its optimal bandwidth and mean squared error. To observe the performance of our proposed kernel estimator, the comparison is made with a Gaussian kernel by using different bandwidths and ROC curve and the area under the curve (AUC) are calculated. For illustration, Kidney cancer data is used and the logistic kernel is found more pragmatic and sensitive biomarker to detect Kidney cancer. The outstanding performance of logistic kernel is also observed in simulation studies and we recommend using nonparametric ROC curve using logistic kernel.

Kooperatyvo „Dailė“ 1941–1945 m. veikla: Lietuvos dailės gyvenimo organizavimas okupacinių režimų metais
Authors: Dargužaitė Rasa
Published: October 2023

Straipsnyje aptariama „Dailės“ kooperatyvo, veikusio labai sudėtingu laiku, Antrojo pasaulinio karo metu, istorija. Keliami klausimai: kokio pobūdžio tai buvo įstaiga, kokios priežastys lėmė jos įkūrimą, kokią funkciją atliko ir koks teko vaidmuo, organizuojant Lietuvos dailės gyvenimą, suvaržytą okupacinių režimų valdžios? Teigiama, kad kooperatyvas, įkurtas pirmos sovietų okupacijos metu, sėkmingai veikė ir nacių okupacijos laikotarpiu, nes centralizuotas įstaigos valdymas buvo parankus abiem režimams. Atliekant tyrimą išryškėjo, kad „Dailės“ kooperatyvo veikla buvo labai įvairi, joje dalyvavo ir profesionalūs dailininkai, ir tautodailininkai; rūpintasi jų darbų prekyba, užsakymų paskirstymu, kooperatyvas turėjo dirbtuves, teikė finansinę paramą ir žaliavas, prisidėjo organizuojant parodas.
SOCIAL AND CULTURAL FOUNDATIONS OF THE GENESIS AND FORMATION OF ANCIENT GREEK QUASI-LEGAL CONCEPTS
Authors: Афанасьевский В.Л.
Published: October 2023

The representations of Hellas demonstrate an outstanding phenomenon of the ancient world. The article is devoted to the explication of the socio-cultural foundations of the emergence and formation of proto-legal phenomena of ancient Greece. The author substantiates the notion that the basis of proto-legal forms is a rite of initiation as one of the mechanisms of transition from one state to another. Quasi-legal phenomena can be formed only outside the primitive context of tradition (doxa), subject to the transition from mythological understanding of the world to the rational tools of its construction. This is expressed from doxa and feminine to aletheia (truth). It is aletheia that symbolizes the transition from myth to rationality, and consequently to rational correctness (right). The article also considers the fact that the Hellenes preferred oral law to its written form. This also led to the fact that the laws did not work to protect the property interests of individuals, but their effect was related to the political life of the polis. The importance of litigation in the polis was also great, but it was conducted only in the perspective of a just decision, and not as a decision in accordance with the law. All this, as the article emphasizes, led to the fact that Rome, rather than Hellas, became the basis of the formation of Western civilization and the Western legal tradition.
REVISITING THE CONCEPT OF MULTIPLE CRIMES AND ITS FORMS IN RUSSIAN CRIMINAL LAW
Authors: Терещенко А.И.
Published: October 2023

В статье анализируется понятие множественности преступлений, вычленяются присущие ей признаки, позволяющие узнать или отличить ее от иных понятий смежного характера. Изучению подвергаются также формы множественности преступлений, многообразие мнений и суждений, высказываемых в доктрине на этот счет. Устанавливается факт отсутствия отрицания в доктрине лишь двух форм множественности: совокупности и рецидива, то есть тех форм, что нашли закрепление в Общей части УК РФ. Констатируется, что выделение всех иных форм множественности преступлений весьма дискуссионно. Усилению таких споров способствовал и сам законодатель, который стал чаще использовать в УК РФ, его Особенной части, такие признаки, как неоднократность, систематичность, судимость; закреплять составы, не имеющие признака неоднократности, но предполагающие административную преюдицию. Все это не могло не отразиться на понимании множественности преступлений, ее форм, усложнив восприятие данных категорий и актуализировав тему исследования. Результатом теоретических изысканий стали предложения о внесении изменений в УК РФ, призванные способствовать совершенствованию регламентации института множественности преступлений. Обоснована, в частности, целесообразность выделения норм о множественности преступлений в отдельную главу УК РФ с закреплением в ней определения множественности.

The article analyzes the concept of a plurality of crimes, singles out its inherent features that allow you to recognize or distinguish it from other concepts of a related nature. The forms of the multiplicity of crimes, the diversity of opinions and judgments expressed in the doctrine on this subject are also being studied. The fact of the absence of negation in the doctrine of only two forms of plurality is established: totality and recurrence, i.e. those forms that have found legal consolidation in the General Part of the Criminal Code of the Russian Federation. It is stated that the allocation of all other forms of multiplicity of crimes is highly debatable. The legislator himself also contributed to the strengthening of such disputes, who began to use more often in the Criminal Code of the Russian Federation, its Special Part, such signs as repetition, systematicity, criminal record; to fix compositions that do not have a sign of repetition, but suggest an administrative prejudice. All this could not but affect the understanding of the multiplicity of crimes, its forms, complicating the perception of these categories and updating the research topic. The result of theoretical research was proposals for amendments to the Criminal Code of the Russian Federation, designed to promote improving the regulation of the institution of multiple crimes.

La región latinoamericana ha sido pionera en la implementación del etiquetado frontal de advertencia nutricional (EFAN), mismo que ha demostrado su eficacia y efectividad para identificar correctamente cuando un producto contiene cantidades excesivas de nutrientes asociados a Enfermedades no transmisibles (ENT). Sin embargo, ningún país del Sistema de la Integración Centroamericana (SICA); que incluye a Belice, Costa Rica, El Salvador, Guatemala, Honduras, Nicaragua, Panamá y República Dominicana, lo ha adoptado. Por esta razón, el Instituto de Nutrición de Centro América y Panamá, convocó a un grupo de expertos de la academia y la sociedad civil con el objetivo de establecer una postura técnica, basada en la mejor evidencia científica, en relación al etiquetado frontal para los nutrientes críticos de alimentos y bebidas pre- envasados en la región centroamericana. Se presenta evidencia específica de la región del SICA que demuestran la superioridad del EFAN frente a otros etiquetados como las Guías Diarias de Alimentación (GDA), el semáforo y el Nutriscore para seleccionar opciones más saludables. Dentro del marco de los derechos de la niñez y de los consumidores, se brindan argumentos y se hace un llamado a los gobiernos para la pronta adopción del EFAN como una política costo-efectiva para la prevención de ENT. Además, se proveen recomendaciones para su monitoreo y evaluación, así como recomendaciones de otras políticas costo-efectivas como la regulación de la publicidad de alimentos no saludables dirigido a la niñez y adolescencia, entre otros, para la prevención de las ENT y la creación de ambientes y sistemas alimentarios más saludables y sostenibles.

The relevance of the task of modeling human behavior posed in the article is associated with the need for active development of the economy, ensuring the involvement of an increasing proportion of the young population with higher and secondary specialized education. As a result of state incentives for business, more and more people are ready to receive higher education or continue to study at the next levels. When studying the processes of managing the social behavior of subjects, the “system of systems” (SoS) approach was used, within which various methods of modeling, simulation and analysis are developed and studied. The simulation is based on the multi-agent principle, the mechanism of which allows analyzing the behavior of the self-organization of an intelligent agent (social subject) and, if necessary, changing its behavior. The ideal approach for implementing the modeling of a multi-agent system (MAS) of the behavior of an agent is the evolutionary simulation methodology (ESM), which allows developing a set of interconnected optimization simulation models that implements the property of self-organization of intelligent agents. The basic principles of self-organization control are formulated, which is based on the theory of equilibrium random processes (RSP), which provides the possibility of influencing any available parameters and in any combination of them using ESM. The ways of adapting ESM in relation to modeling the process of social self-organization of a young person are considered, and a graphical interpretation of social development is proposed, two parameters are used as phase coordinates: social status and income level. Models of indirect methods of management, choice of the direction of development of a person’s career growth in the production management system based on dynamic programming have been developed. Examples of ESM implementation are given.

The work is devoted to the development of models for the automated formation of competencies of a cybersecurity specialist based on a scenario approach. The relevance of the work is determined by the need to timely update the requirements for professional competencies of a cybersecurity specialist in the context of the development of methods and tools for information warfare and the lack of a theoretical apparatus that allows automating this process. The purpose of this work is to develop models for the automated formation of competencies of a cybersecurity specialist based on a scenario approach, which allow analyzing information about the actions of a cybersecurity violator and, based on this information, determining the current set of professional competencies of a cybersecurity specialist. The task of developing models for the automated formation of competencies of a cybersecurity specialist based on a scenario approach is to develop a model of actions of a cybersecurity violator and an associated model of a countermeasure system that determines the actual set of competencies of a cybersecurity specialist. In contrast to existing expert approaches to determining the professional competence model of a cybersecurity specialist, this paper uses a scenario approach that allows describing scenarios of actions of a cybersecurity violator at a formalized level, integrating the data obtained into the appropriate graph model and forming an activity professional model of a cybersecurity specialist based on optimizing the structure of the system counteraction. The set of developed models for the automated formation of competencies of a cybersecurity specialist based on a scenario approach takes into account many factors of information confrontation, such as: techniques and tactics of cybersecurity offenders, their corresponding methods and tools of counteraction. The proposed approach of structuring the countermeasure system in the form of a set of interrelated modules based on the results of the analysis of attack scenarios, techniques and corresponding tactics used by the violator of cybersecurity allows taking into account the features of attacks that are most often implemented, forming a set of professional actions of a cybersecurity specialist based on the use of appropriate methods and tools to counter these techniques grouped by functional modules. Analysis of the results of the conducted computer experiment showed the operability of the proposed models for the automated formation of competencies of a cybersecurity specialist based on the scenario approach.

Currently, digitalization processes are actively developing. Digital tools make it possible to strengthen a systematic approach to monitoring, analyzing and forecasting socio-economic indicators. The introduction of information and analytical systems (IAS) for the study of socio-economic processes improves the decision-making process in public administration and it is an urgent task. This paper outlines the principles and approaches to the analysis and forecast of socio-economic processes, implemented in the construction of an information-analytical system. The structure of the IAS includes a database of statistical data, an analytical subsystem and a subsystem for visualizing the results. The database is developed in the MS SQL Server program and it uses official statistical data posted on the websites of state statistics, the Federal Treasury of the Russian Federation, ministries and departments. It contains information on the total population and in the division by groups, on the population density in the distribution by age of inhabitants; fertility, mortality, natural population growth, migration; statistical data on human and production resources, gross regional product. The analytical subsystem of the IAS is developed in the Microsoft Visual Studio environment and implemented in the high-level C# programming language. It contains algorithms for analysis, modeling and forecasting indicators of regional socio-economic processes based on the integrated use of dynamic models of various types. Visualization and display of the results of the work of the IAS is given in the form of tables, graphs, diagrams, cartograms according to official statistical data of one of the regions of the Russian Federation – the Udmurt Republic. The developed IAS, unlike other information systems, analyzes not only indicators characterizing the state and dynamics of the socio-economic system, but also examines the structure of ongoing processes in terms of time, territory, and age of the objects under study. This system allows to quickly track changes in the dynamics and structure of socio-economic indicators and provide it to decision makers in a timely manner.

Course correction: the role of reflective writing assessment in a post-pandemic academic literacy course
Authors: Schutte Nicole , Van Zyl Zhandi
Published: October 2023

In this conceptual paper, borne from the experiences of two ccademic literacy lecturers at the NWU, we ask, regarding elements of assessment, how we can sensibly adapt an intervention-style writing course in a post-Covid higher education context. We propose a course correction model, applicable to academic literacy writing courses, to address the pedagogical lacunae highlighted in a pre-pandemic context and compounded in the post-pandemic higher education context. We argue for the adaption of this writing course to contend with the under-preparedness of students for higher education, the issue of online learning and resultant student cognitive overload and additional challenges, such as the rapid development of AI and its effects on teaching and learning, and specifically writing courses.
An important element which needs to be reconceptualised within the context of our compounded problem, is that of the writing assessment. In this paper we argue for moving away from placing major emphasis on assessing the final product of writing and shifting some focus to the pedagogical value of examining the student’s journey of writing. We therefore propose incorporating reflective writing as a significant element of assessment through our reflect-rewrite-model. The goal of this proposed model is to create a space for fostering student self-awareness, responsibility, critical thinking, and evaluation skills. Such outcomes should then contribute to the creation of effective and contextually relevant, academic skills development, which in turn should positively influence student success and mitigate some of the issues currently experienced in the module offering.

Accelerating Polyhedral Discrete Element Method with CUDA
Authors: Wen Tongge , Zeng Xiangyuan
Published: October 2023

This paper presents an efficient CUDA-based implementation of a nonspherical discrete element method where irregular particles are described by using polyhedrons. Two strategies are employed to exploit the parallelism of the numerical method. One is to perform contact detection based on the contact pair level instead of the traditional particle level. The second is to reduce the computational burden of each kernel function by allocating thread blocks reasonably. Contact detection between potential contact pairs is the most complicated, time-consuming, and essential process for the polyhedral discrete element method. The linear bounding volume hierarchies are introduced to fix this issue. The hierarchies of the bounding volume tree are organized in a spatially coherent way. Such a structure can minimize branch divergence and is very suitable for parallel implementation with GPU. Two numerical examples are presented to show the performance of the code. It is found from the scenario of two sphere collision that improving the mesh resolution of polyhedral particles can reduce the computational error while slowing down the computational speed correspondingly. A trade-off must be made between accuracy and efficiency. The other example of self-gravitating aggregation demonstrates the code is convergent, stable, and highly efficient. Particularly, with a mainstream GPU, the proposed method easily performs hundreds of times faster than the serial CPU code that does the same function.
