A sexualidade envolve um processo complexo de descobertas que está diretamente relacionada com a saúde sexual, reprodutiva e mental. O acesso à educação sexual é fundamental para a Educação de Jovens e Adultos (EJA), marcada por diversidade etária e vulnerabilidade social. Este estudo avaliou o conhecimento sobre sexualidade e comportamento sexual de estudantes da EJA. Trata-se de uma pesquisa observacional de corte transversal, quantitativa e analítica, que utilizou SPSS/25, considerando p<0,05, e os testes não paramétricos Mann-Whitney, Kruskal-Wallis e Qui-quadrado. Participaram da pesquisa 189 estudantes da EJA de Imperatriz - MA, com aplicação do questionário avaliativo. Os estudantes estão mais propensos a utilizar preservativos masculinos. Na primeira experiência sexual, a maioria não adotou o uso de preservativos e há uma correlação entre essa falta de prevenção inicial e a tendência a não utilizá-los em experiências subsequentes. O sexo masculino apresenta menor conhecimento sobre sexualidade, especialmente no que diz respeito à prevenção da gravidez. Indivíduos desempregados têm um entendimento mais limitado sobre sexualidade. O comportamento sexual de risco é mais prevalente entre os alunos com menor conhecimento sobre sexualidade. Recomenda-se a realização de estudos específicos sobre sexualidade na população da EJA, para uma melhor compreensão dos impactos na saúde desse grupo.

Authors: Ferreira de Oliveira Antônio Augusto , Reyes-Bueno Fabián , Stumpf Gonzalez Marco Aurelio , Da Silva Éverton
Published: February 2025

Mass appraisal has significant applications, such as urban planning, real estate appraisal, and property tax. Due to the challenges of analyzing massive models, they are often developed using semi-automatic assessment methods and machine learning techniques. This article explores different appraisal model methods that utilize statistics and machine learning. It also looks at incorporating spatial information to see if the chosen method can effectively capture the typical spatial dependency of the real estate market. This can help reduce the spatial autocorrelation observed in the residuals. The study compared nine machine learning methods with traditional statistical approaches using a dataset of over 43,000 apartments in Fortaleza, Brazil. The results of the machine learning algorithms were similar. The XGBoost minimized spatial autocorrelation. The easiest interpretations were with MRA, M5P, and MARS techniques. Although, these techniques had the greatest residual spatial autocorrelations. There is a trade-off between the methods, depending on whether the aim is to improve accuracy or provide a clear explanation for property taxation.
Alternative methods for measuring the influence of location in hedonic pricing models
Authors: Stumpf Gonzalez Marco Aurelio , Erba Diego Alfonso
Published: February 2025

The effects of location play a crucial role in the real estate market, encompassing aspects of accessibility and neighborhood. However, these are elements that are not directly measurable. There are traditional ways to consider location, usually through subjective measures based on professional experience, through proxy variables. Understanding these elements is vital for estimating real estate values, whether for legal, commercial, or tax purposes. Furthermore, seeking more objective options is a relevant issue to broaden the justification of estimated values and to enable the development of mass appraisal models. This article proposes and evaluates alternative solutions based on statistics, machine learning, and geostatistics to estimate location. A study was conducted using market data from Novo Hamburgo, southern Brazil, verifying the feasibility of the options presented. Satisfactory statistical results demonstrate the viability of the proposed approach.

Published: February 2025

The rapid development of digital technologies, combined with global events such as the COVID-19 pandemic and geopolitical changes, has significantly transformed the nature of interpersonal communication. This section of the monograph focuses on the phenomenon of digital empathy, which is defined as the ability to perceive, interpret, and respond appropriately to emotional signals in a digital environment. The purpose of this study is to explore the key challenges and opportunities associated with digital empathy in the context of virtual communication, as well as to identify practical strategies for enhancing empathetic interactions in digital spaces. The methodology of the research involved a combination of qualitative and quantitative approaches. A comprehensive survey was conducted among residents of selected EU countries and Ukraine to assess perceptions of digital empathy, its importance in professional and personal interactions, and the effectiveness of different digital formats for expressing emotions. Additionally, analytical methods were used to systematize data on digital empathy skills, challenges, and potential risks associated with virtual communication. The results of the study revealed that video communication is perceived as the most effective format for conveying empathy due to the presence of non-verbal cues such as facial expressions and vocal intonation. Voice messages also demonstrated significant potential for emotional expression, while text-based platforms like chats and instant messengers were moderately effective, often leading to misunderstandings due to the absence of intonation and visual signals. The study highlighted key challenges, including the phenomenon of "emotional noise," which encompasses issues such as incomplete information, decreased sensitivity to emotional cues, and information overload. Furthermore, risks such as cyberbullying, emotional burnout, and communication distortion were identified as critical threats to digital empathy. The practical value of this research lies in its recommendations for implementing digital empathy training programs, which are essential for fostering meaningful connections in virtual environments. The study emphasizes the importance of integrating emotional intelligence development, interactive learning methods, and the use of advanced technologies such as AI and VR to enhance empathetic communication. By addressing both the psychological and technological dimensions of digital empathy, the findings offer valuable insights for improving interpersonal relationships, reducing conflicts, and creating emotionally supportive digital spaces in professional, educational, and social contexts.

Published: February 2025

The Goods and Services Tax (GST) has had a profound impact on the fast-moving consumer goods (FMCG) sector in India, particularly in Karnataka’s Mysore and Mandya districts. This study explores the perceptions of 400 consumers and 100 dealers regarding GST’s implications on various FMCG products. Employing statistical tools such as KMO and Bartlett’s test, principal component analysis, and varimax rotation, the research evaluates GST’s effects on consumption patterns, pricing, and compliance requirements. The analysis reveals significant concerns among stakeholders, including the high rates applied to luxury items, compliance complexities for small-scale dealers, and price sensitivity among consumers. While essential goods with lower tax rates are positively perceived, higher rates on processed and premium products deter affordability and profitability. The study emphasizes the importance of simplifying GST rates and enhancing awareness programs to improve understanding and compliance. Recommendations include tax structure reforms, targeted education initiatives, and policy measures to support small-scale dealers. By addressing these issues, the study aims to optimize GST’s impact on the FMCG sector, ensuring equitable benefits for both consumers and dealers while fostering economic growth. This research provides actionable insights for policymakers to refine GST implementation for better socio-economic outcomes.

Successful mastering of economic disciplines requires not only passive assimilation of theoretical positions, but also the development of critical thinking, the ability to analyze economic data, the ability to build and interpret economic models, as well as apply the acquired knowledge to solve practical problems. The activation of students' cognitive activity will make it possible to more effectively form the necessary competencies, providing a deep understanding of economic processes and prepar-ing graduates for successful professional activity in a dynamically changing economic environment. Without the active involvement of students in the learning process, achieving these goals is unlikely.
Development of the system for recognition of car license plate using artificial intelligence
Authors: Pekh P. , Hrygorychenko V.
Published: February 2025

The article proposes a technology for creating a license plate recognition system using artificial intelligence. The license plate recognition program is developed in the PyCharm integrated development environment (IDE), which supports Python and provides access to libraries for machine learning and image processing. Libraries for working with images and text, such as OpenCV, imutils, pytesseract, and others, are installed through the PyCharm terminal. For the processing and recognition of license plates, a set of images containing various car license plates was prepared. These images are made from different angles, with different lighting and quality, which is caused by the need to ensure the appropriate response of the program to different input data to ensure its correct operation. After loading the image using the OpenCV library, it is converted to grayscale, since contour detection and image processing are much easier in grayscale. The Canny algorithm was used to detect contours. Contours in the image are used for further identification of the license plate. Determination of horizontal and vertical contours was performed using the Sobel operator. We use Tesseract OCR to recognize license plate text. After the license plate has been recognized, we compare it with those in the database. After setting up the program, it is necessary to test it with different images to make sure the accuracy of license plate recognition. This allows you to detect possible problems in the recognition process, such as low contrast of the image, contamination of license plates or unstable lighting, tilting or distortion of license plates in the image, which can affect the accuracy of recognition

Дослідження впливу захисту інформації на обсяги пакетів даних протоколів інтернету речей
Authors: Ivanchuk O. , Kozel V.
Published: February 2025

У статті розглянуто проблему збільшення обсягів трафіку внаслідок використання шифрування. Для аналізу було обрано пакети даних стандартів Wi-Fi, Bluetooth, 6LoWPAN, а також протоколи ZigBee, WirelessHART і NB-IoT. Було визначено, які частини пакету шифруються і які алгоритми використовуються для цього. Wi-Fi, Bluetooth, ZigBee, 6LoWPAN і WirelessHART застосовують алгоритм AES із 128-бітним ключем, тоді як NB-IoT використовує 128-EEA2 із таким же розміром ключа. Обидва алгоритми (AES та 128-EEA2) вимагають, щоб обсяг даних був кратним розміру ключа, тому до корисних даних додається бітова послідовність для досягнення потрібного розміру. Це збільшує загальний обсяг пакету, що передається. Було проведено дослідження цього впливу, та побудовано графіки, що показують залежність обсягу доповнення від кількості корисних даних. Графіки мають пилкоподібну форму через те, що за певних обсягів корисних даних доповнення досягає максимального значення. Також були обчислені середні обсяги доповнень для кожного стандарту: Wi-Fi - 2.13%, Bluetooth - 10.64%, ZigBee - 24.81%, 6LoWPAN - 23.22%, WirelessHART - 23.08%, NB-IoT - 25.96%. Окремо досліджували середні значення доповнень для пакетів до 64 байт: Wi-Fi - 9.95%, Bluetooth - 16.31%, ZigBee - 8.00%, 6LoWPAN - 11.55%, WirelessHART - 10.12%, NB-IoT - 20.21%. За відсутності обмежень на розмір корисних даних найкращий результат показав стандарт Wi-Fi, а найгірший — NB-IoT. У випадках з обмеженим розміром корисних даних найкращі результати були у ZigBee, а найгірші - у NB-IoT

Published: February 2025

Breast cancer is the most commonly diagnosed cancer and the leading cause of death among female patients, which seriously threatens the health of women in the whole world. The treatments of breast cancer require the cooperation of a multidisciplinary setting and taking tumour load and molecular makers into account. The incidence of breast cancer is constantly increasing in all regions of the world. For this reason, despite the progress in its detection and treatment, which translates into improved mortality rates, it seems necessary to look for new therapeutic methods, and predictive and prognostic factors. Triple negative breast cancer is responsible for more than 15–20% of all breast cancers. Future therapeutic concepts for breast cancer aim to individualize therapy and de-escalate and escalate treatment based on cancer biology and early response to therapy. The article presents a review of the literature on breast carcinoma—a disease affecting women in the world.

The Sustainable Livelihood Approach (SLA) is very relevant in managing coffee commodities in Central Aceh through the Social Forestry program that allows communities to manage forests sustainably. This study used in-depth interviews, focus group discussions (FGDs), and field observations to understand the factors that influence the sustainability of community livelihoods. SLA assesses five main assets, namely natural, human, physical, financial, and social. Although human and physical assets have potential, there is an urgent need to strengthen access to social and financial assets. Limited education, skills, and less solid social networks can hinder community economic development. Although infrastructure and natural resources are supportive, dependence on financial access and cooperation between community members is still a major challenge. To improve community welfare and coffee sustainability, there needs to be increased training and more practical counseling, as well as access to capital through microfinance institutions. Building stronger social networks, with collaboration from external parties such as government and non-governmental organizations, is important to strengthen community solidarity. These steps are expected to increase the economic and social resilience of the community while maintaining environmental sustainability.
The Number of Edge Colorings with Small Independence Number and No Monochromatic $H$
Authors: Hu Xinyu , Lin Qizhong , Nie Jiaxi
Published: February 2025

In 1974, Erdős and Rothschild initiated to study the maximum possible number, known as $F(n,r,k)$, of distinct edge-colorings of a graph on $n$ vertices with $r$ colors which contain no monochromatic copy of $K_k$. It is not well understood but a few of non-trivial cases. Recently, Balogh, Liu and Sharifzadeh (2017) introduced an extension of such Erdős-Rothschild problem: given a function $f(n)$ and a graph $H$, let $RF(n,r,H,f(n))$ be the maximum number of distinct $r$-edge-colorings that an $n$-vertex graph with independence number at most $f(n)$ can have without a monochromatic copy of $H$. In particular, they determined the values of $RF(n,2,K_k,o(n))$ for $k\ge3$ and $RF(n,3,K_3,o(n))$.
Define the forest arboricity of $H$, denoted $arb_f(H)$, as the minimum integer $p$ such that $V(H)$ can be partitioned into $\lceil\frac{p}{2}\rceil$ sets $V_1,\ldots,V_{\lceil\frac{p}{2}\rceil}$ such that $V_i$ spans a forest for each $1\le i\le{\lfloor\frac{p}{2}\rfloor}$, and the last class $V_{\lceil\frac{p}{2}\rceil}$ spans an independent set if $p$ is odd. In this paper, we mainly obtain the asymptotic values of $RF(n,r,H,o(n))$ for $r\in\{3,4,5\}$, where $H$ is any graph with $arb_f(H)=3$ and chromatic number $\chi(H)\ge3$. As a corollary, we have the asymptotic values of $RF(n,r,H,o(n))$ for $r\in\{3,4,5\}$ when $H$ is an odd cycle, or a book (fan) graph.
Independent Removable Edges in Cubic Bricks

An edge $e$ in a matching covered graph $G$ is removable if $G-e$ is matching covered, which was introduced by Lovász and Plummer in connection with ear decompositions of matching covered graphs. A brick is a non-bipartite matching covered graph without non-trivial tight cuts. The importance of bricks stems from the fact that they are building blocks of matching covered graphs. Improving Lovász's result, Carvalho et al. [Ear decompositions of matching covered graphs, Combinatorica, 19(2):151-174, 1999] showed that each brick other than $K_4$ and $\overline{C_6}$ has $\Delta-2$ removable edges, where $\Delta$ is the maximum degree of $G$. In this paper, we show that every cubic brick $G$ other than $K_4$ and $\overline{C_6}$ has a matching of size at least $|V(G)|/8$, each edge of which is removable in $G$.

Metabolic disorders are due to a deficiency of enzymes, which can severely impact health or cause serious complications without treatment. This study aimed to identify the molecular causes of an infant death who had been hospitalized with complicated health problems and metabolism syndrome. Whole-exome sequencing (WES) was used to screen pathogenic variants in the patient’s genome, followed by examination of variants segregation in her parents. The WES analysis identified two homozygous variants, c.[614C>G; 649A>G] in the HMGCL gene of the patient. These two variants co-locate within the exon 7 of the HMGCL gene, resulting in 2 amino acid substitutions, p.[T205S; M217V], in the conservative region of enzyme protein. Sanger sequencing showed that the patient’s unaffected mother and father carried one mutant allele of the HMGCL gene containing two c.[614C>G; 649A>G] variants. The HMGCL gene encodes the 3-hydroxy-3-methylglutaryl-CoA lyase enzyme, which is critical in the ketogenic pathway. The deficiency of this enzyme was reported to be a life-threatening illness in the neonatal period, and two variants detected in this study were also found in a Japanese patient with sudden, unexpected death in infancy. The frequency of these two variants in the Vietnamese in-hour database and their further functional analysis were also reported in this study. The results of this study have explored the molecular etiology that causes the severe, deadly condition of the patient and provide an understanding of the risk of disease in her family.

Introduction. One of the most important reserves for saving material and energy resources in the construction industry is the re-involvement of recycled (concrete) crushed stone in the production sector, in particular for the production of heavy concrete of classes B7,5–B35 for general construction purposes. Solving this problem will practically ensure the implementation of the most important principle of waste-free technological processes (in the production of precast and monolithic concrete and reinforced concrete structures) and create conditions for fulfilling important social, economic and environmental tasks.

Aim. Conducting experimental studies to determine the standardized durability characteristics of concrete and reinforced concrete based on recycled (concrete) crushed stone and natural sand, as well as comparing them with similar concretes based on natural crushed stone and sand.

Materials and methods. For the research, recycled (concrete) and granite (natural) crushed stone according to State Standard 8267-93 were used as coarse aggregates. Natural sand according to State Standard 8736-2014 was used as a fine aggregate. Portland cement according to State Standard 31108-2020 was used as a binder. Superplasticizer C-3 according to State Standard 24211-2008 was used as an additive. The mixing water was used according to State Standard 23732-2011.

Results. Concretes based on recycled crushed stone and natural sand have slightly lower strength, density and identical indicators of water resistance and frost resistance compared to similar concrete based on natural crushed stone and natural sand.

Conclusions. Based on the results of the work carried out, it was revealed that concrete based on recycled crushed stone and natural sand ensures the initial passive state of steel reinforcement and retains the passive state of steel reinforcement for a long time (more than 100 years) with a protective layer thickness of 10 mm. Concretes based on recycled crushed stone and natural sand can be used as traditional structural concretes for general construction purposes.
Comparative studies of moisture protection properties of the lightweight hydrophobic plasters on lightweight fillers in relation to aerated concrete
Authors: Gudkov Alexey N.
Published: February 2025

Introduction. One of the most important properties of facade plasters is their ability to resist the effects of atmospheric moisture or hydrophobicity. Water penetrates into the facade plaster layer by adsorption. In this case, the passage of moisture through the plaster solution is caused by capillary action (water absorption, moisture permeability).

Hydrophobization is a sharp decrease in the ability of materials to be wetted with water and aqueous mortars while maintaining vapor permeability. In this paper, a comparative study of the moisture-proof properties of lightweight mineral hydrophobic plaster based on foam ceramic granules "SPADAR", plaster mixtures with other similar lightweight fillers, in relation to aerated concrete. The values of capillary water absorption of plaster compositions, as well as water absorption by weight and the depth of water penetration into the body of aerated concrete samples uncoated and coated on all sides with the studied plaster compositions were compared.

Aim. To investigate the moisture-proof properties of a plaster composition with foam ceramic granules "SPADAR" and similar plaster compositions (on foam ceramic granules "KERWOOD" (another manufacturer), granular foam glass and perlite sand) in relation to aerated concrete.

Materials and methods. To conduct the study, previously developed lightweight hydrophobic plaster compositions for facade work with a dry density of no more than 600 kg/m3 and aerated concrete samples with a density of 600 kg/m3 were used. Water absorption by weight values of a control sample of aerated concrete, as well as aerated concrete samples coated on all sides with the studied hydrophobic plaster solutions were compared. The depth of water penetration into the body of these samples was also compared.

Results. Water absorption by weight of control samples of aerated concrete and plastered with lightweight plaster mortars and the depth of water penetration into the aerated concrete layer after 1.5 hours were established. The advantages of the plaster composition using foam ceramic granules "SPADAR" are revealed.

Conclusions. Based on the data obtained, the composition of a light hydrophobic plaster mortar was developed using foam ceramic granules "SPADAR" and further studies of these plaster compositions on vapor permeability and frost resistance are planned.
Requirements for permissible pauses of concreting during monolithic works

Introduction. The problem of “monolithicity” of structural concrete under construction has been and remains one of the most controversial in acceptance control in construction practice. The lack of clear criteria for assessing of cold joints presence arising during forced breaks in concreting, as well as differences in concreting conditions and properties of concrete mixtures, are among the main factors causing uncertainty in making a decision to reject the erected structure, or making a decision on the need for repair measures, or recognizing the erected structure complies with the project and does not requiring additional costs to ensure the design operational reliability. Lack of homogeneity of physical and mechanical properties of concrete separate parts of the monolithic structure creates stress-strain states of the power frame of the building that are not foreseen by the project and can provoke a threat to the safety of the structure, and lead to a reduction in the inter-repair service life of load-bearing structural elements.

Aim. The aim of the work is to clarify the conditions of cold joints occurrence when concreting depending on the technological properties of concrete mixtures and laying technology, to develop methods of their diagnosis, as well as the subsequent specification to define of the term “cold joint”, its characterization and formulation of proposals in order to make appropriate changes in regulatory documents.

Results. The results of the performed experiment do not support the requirement of the regulations to consider the boundary of the onset of setting as significant in terms of damage to the structure of concrete and the ability to have a noticeable effect on the drop in average strength due to the “loosening” of the “coarse aggregate – mortar” system. Despite the fact that in the series of such experiments it is required to consider more extended statistics, the obtained trends reduce the probability of identifying the beginning of setting as an indicative boundary of the rheological state, when the influence of vibration on reducing of concrete strength after its subsequent curing under favorable conditions becomes determinant.

Conclusions. The formulated and duplicating each other requirements of normative documents on the boundary condition of loss of conditional “continuity” of concrete properties in the body of the structure at simultaneous placement require revision and clarification based on the analysis of the previously performed and additionally conducted experimental studies.
