Authors: Santa Quintero Ricardo Andrés , García Sarmiento Carolina Andrea , Infante Andrade Juan Esteban
Published: July 2024

La idea para este proyecto nació y se desarrolló a lo largo de seis meses, desde enero hasta junio del 2023, en un semillero de investigación enfocado en la realidad virtual (RV), cuyo objetivo es hacer uso de la inteligencia artificial (IA) para la creación de modelos 3D y presentarlos en un showroom. Se quiso encontrar y comprobar que, haciendo uso de una IA, se pueden presentar modelos 3D en RV. Esto se llevó a cabo teniendo en cuenta una serie de pasos. Para la creación de los modelos, se usó la IA Point-E, mejorando los modelos en el software Blender e importándolos a un showroom, creado a partir del software Unity. Finalmente, se obtuvo un showroom con modelos 3D presentados como un museo, que pudieron visualizarse y manipularse utilizando un kit “HTC VIVE”. Con los resultados obtenidos, se concluyó que fue posible cumplir con el objetivo del proyecto, aunque no son resultados definitivos, dadas las limitaciones tecnológicas actuales; sin embargo, se comprobó que la IA puede generar modelos 3D y pueden ser usados en la RV.
Aggressive War against Ukraine: Rural and Urban Safety in the Context of National and Global Security
Authors: Shepitko Mykhaylo , Shepitko Valeriy
Published: July 2024

The chapter is devoted to reviewing the United Nations Sustainable Development Goals in connection with the aggressive war against Ukraine, launched by Russia in 2022. This war in the heart of Europe affects global and national security, as well as rural and urban security. The threat to security is apparent not only in connection with the threat of expansion of the war to NATO countries but also because of the blocking of trade cooperation and routes that made it possible to provide regions of the world with food and clean water. Thus, the connection between Russia’s aggressive war against Ukraine and national, public, economic, ecological and other types of safety and security issues is obvious. All demonstrated examples highlight war crimes, crimes against humanity and genocide; because of this, international, national, and foreign law enforcement bodies, courts (tribunals), and non-governmental organisations are involved in collecting, checking and evaluating evidence.

Subjectivity of the academic community in the conditions of managerialist management
Authors: Kovalev Vitaly , Dyatlov Alexander
Published: July 2024

The article analyzes the negative effects of managerialist management on the subjectivity of the academic community. The aim of the research: to establish a correlation between the decrease in the subjectivity of the academic community and the managerialist model of higher school management. Two methods were used to collect empirical information: a mass survey of teachers at four universities in Rostov region and the analysis of normative-legal documents regulating the application of managerialist norms to the higher education system. The result of the operationalization of basic concepts (subjectivity, academic community, managerialist management) was the definition of three empirical indicators: 1)perceptions of the academic community about the traditional goals of higher education; 2)resources of the academic community to achieve managerialist goals; 3)the presence of deformations in the professional ethics of academics and teachers. The study confirmed the hypothesis that the implemented managerialist policy has a negative impact on the academic community, reducing its subjectivity. Dysfunctions are manifested in two areas of professional activities of scientists and teachers. The first one is caused by the peculiarities of managerialism. Managerialism in any socio-cultural and socio-political conditions inevitably leads to the substitution of goals for the means of their achievement. This occurs due to the absence of reliable indicators for effective managers to assess the quality of reproducible results of their activities by scientists and teachers. The second direction is related to the loss of freedom in decision-making at meetings of historically established in universities sustainable social practices (meetings of the department, academic councils, dissertation councils, etc.). This is due to the administrative subordination of the academic community to the managerial tasks of the bureaucracy.

Published: July 2024

The differentiation of mesenchymal stem cells (MSCs) into chondrocytes, known as chondrogenesis, is a complex process that plays a fundamental role in cartilage formation and skeletal development. This study elucidates the transcriptional dynamics and phenotypic correlations at various stages of chondrogenesis (early, mid, and late) using RNA-seq data. We focused on the differential expression of transcription factors (TFs) and RNA-binding proteins (RBPs). We identified critical genes during their highest expression periods and generated heatmaps to visualize these temporal patterns. Additionally, we conducted a comprehensive analysis of skeletal dysplasia nosology genes, determining their highest expression periods and phenotypic implications using the DisGeNET database. Our findings reveal that early-stage (D1) gene expression is linked to craniofacial development and limb formation anomalies, primarily involving genes responsible for extracellular matrix (ECM) organization and signal transduction. Mid-stage (D7) genes are associated with cartilage matrix composition and skeletal growth, highlighting roles in chondrocyte proliferation and matrix deposition. Late-stage (D21) genes are implicated in bone mineral density, cartilage integrity, and joint formation, ensuring the maturation and functionality of cartilage tissue. This study provides a detailed analysis of gene expression regulators and their phenotypic correlations during chondrogenesis, offering insights into the molecular mechanisms driving cartilage development and skeletal dysplasias. Understanding these temporal gene expression patterns enhances our knowledge of chondrogenesis and aids in developing targeted therapies for cartilage-related diseases. These findings underscore the significance of time-point analyses in capturing the dynamic regulation of gene expression throughout the differentiation process.

Published: July 2024

A new method was developed for post-modification of porous aromatic framework-1 (PAF-1) with chloride and then amine groups confirmed by different characterizations such as nuclear magnetic resonance (NMR), X-ray photoelectron spectroscopy (XPS), and Fourier transform infrared spectroscopy (FTIR). Compared to PAF-1, the amine-functionalized PAF-1 (PAF-1-NH2) exhibits a 50% improvement in carbon dioxide (CO2) adsorption capacity reaching 42 cm3·g-1 at room temperature and 1 bar, and the uptakes under CO2 concentration in air (4 kPa) and flue gas (150 kPa) also greatly increase. The column breakthrough experiments showed that PAF-1-NH2 can separate CO2 from a simulated flue gas of CO2/N2 (15:85, v/v) indicating its potential applications in post-combustion systems.
Hierarchical metal–organic framework nanoarchitectures for catalysis
Authors: Zhao Bin , Han Ji , Liu Bohan , Zhang Song Lin , Guan Buyuan
Published: July 2024

Metal–organic frameworks (MOFs) have garnered significant attention in the field of catalysis due to their unique advantages such as diverse coordination geometry, variable metal nodes, and organic linkers, facilitating precise structural and compositional control for achieving programmable catalytic functionalities. Although their inherent microporous structure could provide excellent shape selectivity during catalysis, it typically impedes the mass transfer process, thereby reducing the use of internal active sites and overall catalytic efficiency. Additionally, employing single MOFs as catalysts presents challenges in achieving complex catalytic reactions that require multifunctional active sites. In recent years, considerable research efforts have focused on designing and constructing hierarchical nanostructured MOFs to alleviate substrate diffusion limitations by introducing secondary nanopores, shortening diffusion distances via the construction of low-dimensional nanoarchitectures, and constructing multifunctional catalysts by integrating distinct MOFs with suitable functions. This review provides a comprehensive overview of the design, synthesis methods, and formation mechanisms of MOF-based hierarchical nanostructures in recent years. Subsequently, it further highlights their applications in thermal catalysis, electrocatalysis, and photocatalysis, along with the relationship between their hierarchical nanostructures and catalytic performances. Finally, it provides an outlook on the challenges and potential development directions of hierarchically structured MOF nanocatalysts.
Harnessing crosstalk between extracellular vesicles and viruses for disease diagnostics and therapeutics
Authors: Zhu Xinxi , Lin Xiuhui , Hu Liang , Wang Liangxing , Zhu Qingfu
Published: July 2024

Extracellular vesicles (EVs) are increasingly acknowledged as important mediators of intercellular communication, closely related to the occurrence and development of a variety of diseases. Numerous studies have demonstrated that EVs play a multifaceted role in the infection process of viral diseases, elucidating their ability to both facilitate viral spread and inhibit infection progression. These versatile entities not only enhance infection rates and widen the scope of viral infection through the transmission of entire viruses or viral genomes, but also trigger antiviral responses and prompt cytokine secretion near the infection site, thereby fortifying the host's defense mechanisms and safeguarding neighboring cells against infection. This complicated crosstalk between EVs and viral infections prompts a deeper exploration into their roles in potential clinical applications. In this review, we aim to encapsulate the recent advances in understanding the intricate interplay between viruses and EVs, shedding light on the mechanisms underlying this vesicle-to-virion crosstalk. Furthermore, we underscore the significance of harnessing this knowledge for diagnostic and therapeutic functions in combating viral diseases.

Authors: Sutrisno Hadi , Nuryadin Muhammad Rusmin
Published: July 2024

The financial sector has a major influence on economic growth in Indonesia. Good modeling influences the accuracy of economic growth predictions and has an impact on the financial sector. Several models have been introduced to analyze the relationship between the two, but it is necessary to test which of these models is most appropriate. This research aims to find the best model of the financial sector's influence on economic growth in Indonesia. Three models were compared so that the best model was selected, namely the Bayesian Vector Autocorrelation (BVAR), Linear Regression, and Pseudo Poisson Maximum Likelihood (PPML) models. The comparison method was carried out to determine the best model from the third model using various criteria, and then an in-depth study of the best model was carried out by considering various diagnostic tests and stability tests. The analysis results show that the BVAR (2) model is the best model among the three existing models. However, some specific analysis results in the regression analysis model (such as the negative impact on CPS) and the PPML model (such as the high R-square) can be taken into consideration by policyholders in the financial sector in determining policies related to these areas for economic growth.

Published: July 2024

Studies emphasize that learning motivation is one of the primary elements that affect the achievement of learning objectives and at the same time, influences the skill of mathematical problem-solving. Research on the correlation between mathematical problem-solving and learning motivation despite numerous attempts at solutions, the correlation value is heterogeneous, making it inconsistent. This study aims to summarize the effect-size values obtained based on the main research through the correlation meta-analysis method. The literature data collection technique used the Google Scholar database which was selected using the inclusion criteria. Primary studies that fit the criteria consisted of 20 studies published in journals, proceedings, and theses from 2016 to 2022. Three steps of data analysis, including publication bias research, random or fixed effect models, and statistical hypothesis testing, were conducted using the Jeffreys Amazing Statistics Program (JASP) program. The results of the study show that there is a positive influence of learning motivation on students' mathematical problem-solving abilities at the elementary, middle, and high school levels in Indonesia in the moderate category (r = 0,56; p < 0,01). The results of this study suggest educators to further optimize students' learning motivation because learning motivation influences the level of students' mathematical problem-solving ability. Keywords:  Learning motivation, mathematical problem-solving, problem-solving, meta-analysis
ENHANCING MATHEMATICAL CREATIVE THINKING ABILITY: EXPERIMENTATION WITH REALISTIC MATHEMATICS EDUCATION BY EMBEDDING ICE BREAKING IN JUNIOR HIGH SCHOOL
Authors: Ramadhanta Sury Adellia , Simamora Rustam Effendy , Susanti Dwi
Published: July 2024

The effectiveness of Realistic Mathematics Education (RME) in improving students' mathematical abilities has been examined through various research. Meanwhile, the use of ice-breaking (Ib), considered by experts and educational researchers as a highly beneficial tactic for improving learning effectiveness, had yet to be fully explored in the context of integration with RME. The study aimed to examine the effectiveness of Ib-RME (RME integrating Ib) in enhancing students' mathematical creative thinking abilities (MCTA) at SMPN 14 Tarakan, Indonesia. Involving 64 seventh-grade students in a quasi-experimental design, the experimental group adopted the Ib-RME approach. In contrast, the control group followed the conventional teaching method employed by mathematics teachers in the class, including ice-breaking activities as normally implemented in the classroom setting. Data analysis using t-tests revealed a significant improvement in MCTA in the Ib-RME group, confirming the effectiveness of this approach. The research noted that conventional teaching also enhanced MCTA, although to a lesser extent than Ib-RME. These findings contributed to understanding the potential integration between RME and Ib in improving Mathematics learning outcomes, particularly in developing MCTA. The implications could serve as a basis for the development of innovative and effective teaching approaches in the mathematics education. Keywords: conventional learning, ice-breaking, mathematical creative thinking ability, realistic mathematics education, school mathematics.

Published: July 2024

The impact of the mining process including the emergence of Total Suspended Solids (TSS), either directly or indirectly can disrupt the life of aquatic biota, damage environmental sustainability, and threaten the welfare of humans who depend on the water for various daily purposes. To reduce the burden of pollution on water bodies due to coal mining waste, one of the technologies often chosen is the Wastewater Management Plant (WWTP) system, which generally involves the use of settling ponds. This study aims to analyze the total suspended solids in the settling pond, analyze the total suspended solid capacity, and compile recommendations for total suspended solid management efforts to meet environmental quality standards. The total suspended solids (TSS) values in October and November measurements at the inlet were 339.00 mg/l and 712.00 mg/l while the outlet decreased to 42.50 mg/l and 55.00 mg/l. The total suspended solid (TSS) value during the measurement period of January – December 2023 shows that the TSS value at the inlet and outlet for 12 months shows a value below the quality standard. The first settling pond with a capacity of 15,000 m, and the second to sixth settling ponds have a capacity of 3,000 m3  each. To maintain the capacity of the settling pond at around 60% of its maximum capacity, the volume of TSS deposited ranges from 9,000 m3, while in the second to sixth settling ponds, the volume of TSS deposited each ranges from 1,800 m3.

Published: July 2024

Novel technologies have resulted in the unprecedented and dynamic development of transport systems—one of the most important sectors of the economy. The implementation of smarter commuting solutions, in order to improve the processes of transportation, allows for cost and energy saving, better organization of time, and, as a result, an increase in quality of life. Also, this supports the operationalization of the sustainable development concept, enabling a compact and efficient urban transport system to be developed. The purpose of this paper is to analyze smart urban mobility development prerequisites and challenges, taking Gdynia city public and shared transport users’ preferences and transport behavior as a case study. A research hypothesis has been formulated stating that most commuters have sufficient digital competencies and benefit from the available modern technological solutions contributing to smarter and more sustainable urban development. The obtained results prove the importance of the role the digital world plays these days and show how the impact of technology on the transportation sector has helped to develop new opportunities for urban mobility.
ANALYSIS OF THE SPATIAL-ECONOMIC AND SOCIO-PROFESSIONAL DYNAMICS OF TAXI-TRICYCLE DRIVERS IN LOME
Authors: VIMENYO Messan , AGBOGAN Agogno
Published: July 2024

African cities’ fast rate of population increase from 4 to 6% per year and the decline of organized public transport systems are the origin of the rapid development of non-conventional means of transport [2]. The city of Lomé, since its creation in 1897, has experienced growing demography and spatial extension apart from its socio-collective and mobility infrastructure [5]. Faced with the inability of public transport services to meet the demand, we are witnessing the emergence of informal transport solutions such as taxi-motorbikes and taxi-tricycles in response, not only to the demand but also to youth unemployment and the economic crisis. This article focuses on actors in the taxi-tricycle sector. It analyzes the spatial economic and socio-professional dynamics of taxi-tricycle drivers in Lomé. The scientific interest of this article is dual. Firstly, it makes it possible to map the spatial dynamics of taxi-tricycles in Lomé and, secondly, it identifies the problems related to the propagation of the phenomenon of urban taxi-tricycle transport which, until now, has not been apprehended by Togolese researchers. The methodology focuses on the analyses of data (primary and secondary) collected through a literature search, observations, and a survey. A sample of 47 individuals was selected, made up of 40 taxi-tricycle drivers and seven association leaders. The results show that the diffusion of taxi-tricycles is supported by the logic of marginality and informality. The sector contributes somewhat to solving the problems of mobility and unemployment as well as the increase in municipal revenues. Given the difficulties raised by this study, it is imperative that the sector be regulated by the State.

Published: July 2024

Permeable pavement is considered one of the sustainable management options for roadway networks, which mitigates a number of problems associated with stormwater, ground water pollution, and traffic safety. In this study, the economic feasibility, vehicle operation, and environmental implications of implementing permeable pavement in Nablus, Palestine have been determined by selecting the local roadways that satisfy the permeable pavement requirement, such as low traffic volume, grade less than 5%, speed limit up to 50 km/h, and subgrade with good permeability. The total costs of construction and maintenance for both conventional asphalt and permeable pavement have also been compared based on the life cycle cost analysis (LCCA). Finally, the environmental implications such as the expected increase in the amount of ground water and the reduction in water pollutants have been investigated. The results of the analysis show that the permeable pavement is applicable for the local roadways that have satisfied the requirements, which are 61 roadways. Furthermore, it could lead to an annual significant increase in ground water by 107,404.7 m3 and slightly reduce the cost of construction and maintenance by up to 1,912,000 ILS during its life period compared to conventional asphalt pavement. Moreover, applying porous asphalt could enhance vehicular traffic safety by improving skid resistance.

Advanced high-strength steels are important for the automotive sector. Metal active gas (MAG) is the most popular method for joining grades of steel. The goal of the paper is to analyze the mechanical properties of the MAG welding joint made of high-strength DOCOL 1100M intended for the construction of electric vehicles. The manuscript shows a basic understanding of the properties of DOCOL joints. This type of material is characterized by a martensitic microstructure, which makes it difficult to make a proper joint. The tensile strength, metallographic structure, and type of non-metallic inclusions were analyzed as a function of the oxygen amount in the protective gas mixture. Investigations of oxide non-metallic inclusions were carried out using scanning electron microscopy. This article attempts to obtain high joint strength of the electric vehicle structure by controlling the average size of non-metallic inclusions in the weld, which is influenced by shielding gas in the MAG welding process. The solution has application potential for the automotive industry, especially for electric vehicles.

Published: July 2024

A partir do reconhecimento da centralidade do trabalho na vida das pessoas, o presente artigo visa analisar o processo de precarização do trabalho em curso e seus impactos diferenciados sobre os grupos populacionais. O objetivo é identificar como a precarização do trabalho opera sob a perspectiva da divisão sexual do trabalho e da segmentação racial histórica do mercado de trabalho brasileiro. Para tanto, o presente artigo traz uma proposta de conceituação e construção de um indicador multidimensional de trabalho precário, com resultados desagregados por sexo e cor/raça, a partir dos dados da Pesquisa Nacional por Amostra de Domicílios Contínua, do IBGE, para a série histórica 2012-2021. O diferencial do indicador proposto é permitir mensurar a precarização do trabalho em termos de incidência e intensidade da precarização no âmbito das estatísticas públicas oficiais brasileiras disponíveis. Como resultado, embora as mulheres, de uma forma geral, tenham apresentado menores taxas de precarização, elas estão em ocupações mais intensamente precárias do que os homens. Por outro lado, mulheres negras se destacaram como o grupo populacional mais afetado pela precarização em curso, acompanhadas de perto pelos homens negros, evidenciando a importância da análise das desigualdades raciais combinadas às desigualdades de gênero no mercado de trabalho.

It was found that the effective formation of conceptual-analytical and productive-synthetic levels of formation of professional knowledge and skills regarding the design of digital systems of power grid relay protection and automation is possible with the systematic development and use of a generalized model of the teaching content. Based on the study of information models of technical systems, a feature model was adopted as a basic invariant, which includes a set of features of the purpose, construction, principle of operation and parameters of the technical system. It was found that the design process of digital systems of power grid relay protection and automation can be conventionally divided into three stages, namely, the development of the design task, the direct implementation of the design, and the determination of the parameters of operation. Causal chains of knowledge that form the basis of problem solving at these three stages are determined. It was found that the methods of step-by-step decomposition and aggregation are key in building the content of teaching the design of digital systems of power grid relay protection and automation based on causal chains of knowledge. A generalized model of the teaching content design of digital systems of power grid relay protection and automation based on causal chains of knowledge is substantiated. According to the generalized model, the teaching content design of specific microprocessor l systems of power grid relay protection and automation has been developed. With the help of experimental verification, the effectiveness of the teaching content design of digital systems of relay protection and automation based on causal chains of knowledge has been proven. The results of the research can be used in the educational process of professional training of future engineers in the specialty 141 Electric power, electrical engineering and electromechanics.

Currently, there is a constant growth of distributed energy resources, it became necessary to integrate them into the power grid. However, the integration process must consider not only the control parameters of the distributed energy resource but also the parallel operation of several such resources, the parameters of the power system as a whole. At the highest level of control, it is also necessary to consider the economic indicators formed by the energy market. Special devices – controlled inverters – can be effectively used for integration. The most difficult task is choosing a control system for controlled inverters. There are many different control systems such as Proportional-Integral, Deadbeat controllers, etc. The purpose of this paper is to build an information model for controlling distributed power resources. The current control method was used to control active and reactive power. The advantage of current control is resistance to variations in the parameters of the inverter and the external grid, excellent dynamic performance, and higher control accuracy. The proposed approach for building an automatic control system using the Internal model control strategy and taking into account restrictions on the control variable. The advantages of a system with an Internal model control controller compared to a conventional Proportional-Integral controller are the use of a powerful control method based on the object model, the ability to influence the roughness of the system with a separate setting parameter, increased speed with almost complete absence of over-regulation, simplified setup procedure. Such a system is proposed for use in facilities with strict requirements to minimize over-regulation and the speed of working out disturbances and tasks. The PSCAD software app was used to model the work results.

It is noted that although the share of renewable electricity sources continues to grow and develop rapidly, the industry still faces many challenges, including how to continue to reduce electricity losses and annualized costs, improve operation and maintenance efficiency, maintain grid stability, ensure safety and reliability of the power supply system containing renewable sources of electrical energy. It is shown that an effective solution to these problems is possible only on the basis of the analysis of the prospects for the development of local electric power systems that contain renewable sources of electric energy, the development of technical and organizational support mechanisms that will contribute to the construction of modern system (schematic) solutions. It is proposed to apply the potential surface method for building the optimal structure of the rural electrical network during its design and modernization in the presence of renewable sources of electrical energy, which allows optimizing the structure of the network from the point of view of electrical energy losses and reducing annualized costs. The algorithm for forming the structure of power supply systems is described, which implements the simultaneous solution of the tasks of determining the number of load nodes, distributing electrical receivers between them, determining the design of power sources, taking into account the discreteness of the design of system elements. The results of numerical modeling based on the proposed algorithm are presented on the example of solving the problem of reconstruction of a section of the rural electricity network.

Accurate analysis and prediction of the transformer's thermal condition depending on the operating mode, for example, in cold winters with a shortage of electricity, allows for effective planning of regular maintenance. In the course of the work, mathematical models were created to analyze the thermal state of the transformer, in particular, models for finding the temperature of the upper layers of oil and the highest temperature on the transformer winding. The data from these mathematical models were verified by comparing them with an already identified analog model. It was determined that the difference between the results is no more than 7 %. It has been established that the thermal state of the transformer is influenced by the ambient temperature much more than by the load. This is due to the fact that without cases of overload and emergencies, the load on the transformer, depending on the season, does not change significantly. It has been determined that the highest time utilization and the highest temperature on the high and low voltage windings are observed in August, which coincides with the peak ambient temperature. The lowest temperature on the windings and the lowest life utilization of the transformer are observed in January, which also correlates with the lowest ambient temperature. It is determined that under such operating conditions, given that the nominal service life of the transformer is 20 years, the actual service life will be approximately 90 years. It was also found that the reduction in service life in winter is 5 times less than in summer. This allows us to predict a reduction in maintenance needs during the cold months and more intensive maintenance in the summer. In addition, such models can predict potential problems and emergencies, which can significantly reduce the risk of unforeseen outages and increase the reliability of power supply. Regular monitoring and analysis of the thermal condition of the transformer makes it possible to respond quickly to changes in operating conditions and make timely maintenance decisions, which helps to optimize costs and increase the efficiency of power grids.
