Published: September 2024

The present study investigated the correlation between the degradation processes of cultural heritage and the environmental parameters of the semi-confined site that houses it. The latter is a semi-underground room (nymphaeum) found in the Archaeological Park of Baia (Italy) dating back to the third century; it is decorated with marine motifs and painted with frescos techniques from the same period. Relative humidity and temperature were hourly registered, and the collected data were used to derive daily and annual profiles. The effects of microclimate induced degradation were investigated employing various techniques, such as Ion Chromatography for the chemical characterisation of deposits, and Thermography, for the individuation of biological layers. The data obtained showed that the underground environment, partially submerged by rising brackish water, was affected by the presence of biodeteriogens, whose distribution and growth is strongly favoured, above all, by the environmental parameters and by the substrate characteristics. All the data were then cross-referenced to obtain a complete knowledge of the conservation frameworks of the environments, essential to identify the most compatible and effective restoration methodologies to be applied in the conservation of the nymphaeum.

Three-dimensional (3D) technologies play a crucial role in the philological reconstruction of archaeological contexts. The integration of technology and archaeological evidence has made it possible to develop 3D virtual reconstructions, providing valuable insights into the temporal evolution of archaeological sites. This innovation serves as a significant research and analytical resource, enabling the visualisation of possible scenarios related to archaeological contexts that have significantly changed over time. Moreover, understanding these changes, the past and its relevance to the current context could pose a challenge to the general public. This work aims to illustrate a scalable rendering system using open-source Web3D apps and platforms, allowing access to information, 3D models, and descriptions to enhance the experience of artworks.

Published: September 2024

The creation of physical replicas of statues is not a novel concept; however, it continues to present various aspects worthy of investigation. On one hand, there is the need to optimize digital models for their physical experience while retaining distinctive features. On the other hand, there is the development of a robust pipeline for constructing reliable physical copies concerning morphometrics and materials. Both stages necessitate experimentation and comparisons, allowing for the validation of processes to achieve scientifically accurate results. This article, using the case study of the head of Sant'Elena preserved within the mausoleum of the same name, suggests comparing different processes of physical and digital 3D acquisition and reproduction of the artwork. The goal is to enhance its accessibility for individuals with visual impairments.

The reconstruction of infant biological history and mortality profiles provides biocultural insights into adulthood morbidity, maternal health, parental caregiving practices, and social dynamics. However, interpreting biological data from cremated infant remains in archaeological contexts can be challenging due to their often poor preservation and potential biases. Tophets, sanctuaries for distinct burial of cremated infant remains present in several Phoenician-Punic colonies in the Mediterranean area, offer an ideal case study. This study presents the first virtual histology performed in X-ray Microscopy-based imaging (XRM) on a sample of crowns of cremated deciduous teeth from the Tophet of Motya (Sicily, 6th century BC). The observation of the Neonatal Line (NL) in enamel tissue offers important informations on the community demographic profile, age-at-death classes and life-histories of the buried individuals. Results are consistent with previous studies on other human remains found in the main Tophets in Mediterranean basin and highlight the importance of using non-invasive techniques to collect and analyse data that are useful for the interpretation of newborns and infants burial practices.

Authors: Mancini Simona , Pehlivanoğlu Serpil Akӧzcan , Todorovic Nataša , Ozden Selin , Guida Michele
Published: September 2024

Building materials (BMs) can cause significant gamma dose indoors due to their natural radionuclide content. In 2013, the European Directive 59/2013/EURATOM introduced, in annex XIII, a list of types of BMs of interest for the content of gamma-emitting radionuclides among which materials or additives of natural igneous origin, such as granitoids, tuff and lava, are included. These materials have been largely employed for decorative and structural purposes in the course of centuries in the Italian heritage buildings. Aim of this study is to assess the contribute of BMs in terms of alpha exposure. Six samples of different materials, characterized in a previous study by the authors in terms of radiological content by means of a gamma spectrometry, have been analyzed in order to determine the specific exhalation rate of 222Rn, the radon emanation coefficient and excess in indoor radon concentration. Results confirm that BMs of natural igneous origin can play an important role in terms of alpha radiation dose and internal exposure due to the inhalation of the alpha particles emitted.

Published: September 2024

In the last few years, 3D printing has gained widespread use in archaeology and cultural heritage fields, from research and conservation to enriching museum experiences. This study focuses on Fused Deposition Modeling (FDM) technology to assess the quality of printed replicas of archaeological human remains. A cranial model was 3D printed (3DP) from Computed Tomography (CT) data of an 8-year-old patient to simulate the remains of an archaeological skull. Eight copies were then printed and subjected to CT scanning to compare them to the original model through an objective measurement method based on image analysis. The proposed method investigates print variability and considers potential sources of error to assess the dimensional compatibility of the model before and after printing. Results showed an increasing error, up to 15 %, with higher levels of model detail. These results are discussed with reference to a metrological approach, highlighting the need for further research into optimizing 3D printing quality control, including through the definition of a standardized protocol to obtain archaeological replicas faithful to the originals.

Authors: Caruso Giovanni , Orazi Noemi , Paoloni Stefano , Zammit Ugo , Mercuri Fulvio
Published: September 2024

Pulsed thermography is a well-established method for the non-destructive analysis of cultural heritage items. This technique has been recently applied by the authors of this paper for reading written scraps, used for the making of bookbinding of ancient manuscripts, located between the end papers and the covers. The readability of the hidden text depends on several geometrical, optical and thermal parameters characterizing the typology of paper and the ink employed. To this end, a comprehensive mathematical model was developed by the authors for analyzing the influence of the various involved parameters. In particular, two indices were introduced, namely the signal contrast and the distortion index, used to quantitatively characterize the hidden text readability. Several numerical simulations are reported for assessing the dependence of the contrast and distortion from various parameters appearing in the model. Finally, a preliminary application to the analysis of original books is also presented.

Published: September 2024

The analytical characterization of mortar samples from the Roman archaeological site of Frielas, located in Lisbon, Portugal; was carried out by means of X-diffraction (XRD), thermogravimetry (TGA-DTG), optical microscopy and scanning electron microscopy coupled with energy-dispersive spectroscopy (SEM-EDS), acid attack and granulometric analysis. A total of eighteen mortar samples were collected from the different structures of the villa with different functional uses (render, filler, and floor). The results showed a similar composition of binder, while differences in aggregates allowed to establish several groups. Results were discussed as evidence of manufacturing techniques, production technologies, and provenance of possible raw materials. There was no prominent variation that can suggest a different chronology between the group of samples. Though, it is assumed that there might be some renovation, restoration, or partial rebuilding that occurred in the same period. In terms of production technology, proportions ruled by Vitruvius were not followed.

Authors: Yusenko S. R. , Zubkova T. S. , Sorokin A. S. , Khaltourina D. A.
Published: September 2024

Introduction. The growing prevalence of obesity in the world and the accumulated scientific data and practical knowledge have prompted the World Health Organization to declare obesity a global pandemic and a worldwide public health crisis. According to research, in 2015, 603.7 million adults and 107.7 million children worldwide were obese, and the overall prevalence of obesity was 12.0 and 5.0 %, respectively, while overweight caused 4.0 million deaths and 120 million lost years of life.

   The purpose of the study: to assess trends and age and sex structure of obesity prevalence in Russia according to different sources.

   Materials and methods. We calculated the prevalence of obesity using data from Rosstat (2018–2023) and the Russia Longitudinal Monitoring Survey (1994–2022), as well as the structure of obesity by sex and age groups in dynamics, and the structure of obesity by degree (2022).

   Results. According to the results of calculations based on Rosstat data, the prevalence of obesity among men increased from 17.8 % in 2018 to 20.9 % in 2023, and among women from 24.5 % to 28.6 %, respectively. According to calculations based on data from the Russia Longitudinal Monitoring Survey, the prevalence of obesity among men increased from 8.5 % in 1994 to 16.6 % in 2022, and among women from 21.1 % to 27.5 %, respectively. After 2012, there was no significant increase in obesity prevalence in any of the age groups, with the possible exception of 15–24-year-old men and women aged 65 and older. The data suggests that the obesity epidemic in Russia has stabilized and the increase in the prevalence of obesity in recent years was largely due to the population aging. Also, Rosstat data show an increase in obesity prevalence during the COVID-19 pandemic from 23.0 % in 2019 to 25.0 % in 2021, while the rate remained at the same level (24.9 %) in 2022. In the structure of obesity calculated on the basis of Rosstat data, obesity of the I degree prevails both among men (80.5 %) and women (68.1 %).

   Conclusion. The growing prevalence of obesity in Russia, given the associated risks of morbidity and mortality, raises concerns and requires appropriate public health measures.

Introduction. Sociological surveys are a reliable source of information about the quality of medical care provided. Assessing the subjective opinions of all participants in the treatment and preventive process about the organization of medical care allows for timely adjustments to the volume and quality of medical services provided. The study of subjective assessments of medical personnel about the quality of medical care provided determines its effectiveness and requires additional research.

   The purpose of the study is to study the opinions of medical workers, assess the influence of possible factors on the responses of respondents, in connection with the inclusion of remote blood pressure monitoring in their functional responsibilities.

   Materials and methods. Study was conducted on the basis of two city clinics of St. Petersburg No. 19 and 91. The materials were data from a sociological survey of medical workers who took part in organizing the provision of medical care using remote blood pressure monitoring to patients of the cardiology follow-up group in the period from 2018 to 2022.

   Results. An analysis was carried out of the influence of some factors on the respondents’ answers in connection with the inclusion of remote blood pressure monitoring in their functional responsibilities.

   Conclusion. Data processing showed that, in general, this led to an increase in the satisfaction of medical workers with various aspects of professional activity related to communication processes in the team – improved mutual understanding with colleagues and management and a decrease in the number of conflicts with patients. Regarding factors of labor organization and remuneration, significant resources were noted to determine directions for their solution.
Problems of depression in neurological practice
Authors: Zarubina N. V.
Published: September 2024

Introduction. Depressive disorders have ceased to be only the task of psychiatrists. Depression is detected in patients with a somatic and neurological profile as a reaction to the disease, and may be the cause of the disease. The number of above-mentioned pathologies remains unknown to date. The main task for health care organizers is the need to build an algorithm for the identification, registration and treatment of depressive disorders in patients with combined pathologies. This article discusses depressive disorders in patients with multiple sclerosis.

   The purpose of the study: to study depressive disorders and factors influencing depression in patients with multiple sclerosis.

   Materials and methods. 203 patients with clinically confirmed diagnosis of MS participated. Taking into account the course of the disease, MS patients were distributed: with a remitting (RRS) type of MS course 88.2 % (179 people) and 11.8 % (24 people) with a secondary progressive course (RRS). The average age of the examined patients with remitting course (RRS) ranged from 15 to 63 years, on average 38 ± 10 years. The age of the examined patients with HPV is in the range from 29 to 65 years, on average (46 ± 9.00) years. The majority of patients had a disease duration of less than 20 years, on average 8.23±6.57 years. The average age of onset of the disease is 30.2±10.5 years. The duration of the disease is 9.84 ± 0.73 years, while the level of disability of patients (score in points on the Expanded Disability Status Scale/EDSS) at the time of examination was 2.89 ± 0.16 points. The disability index varied in patients with RRS2.89 ± 0.16 points, in patients with RRS (5.0 ± 0.24) points.

   Results and discussion. 55.7 % (113 people) of MS patients were diagnosed with depression, of which 80.5 % (91 people) and 19.5% (22 people) of patients with a remitting (RRS) course and a secondary progressive course of the disease (RRS). More than 54.8 % (62 people) had mild and moderate depressive manifestations, 39.8 % (45 people) most often had mixed anxiety-depressive disorder, recurrent depressive disorder, then depressive episodes. It was revealed that the development of depression in patients with a remitting course is influenced by: «disease duration» PC p = 0.00333**, «disability level» p = 0.0457* and «personal anxiety» p = 0.0194. In patients with a secondary progressive course, depression is influenced by the following factors: «situational» p = 0.0398* and «personal anxiety» p = 1.740. The social status determined that patients with «MS without depression» who were married were statistically less likely to suffer from depression and maintained their working capacity longer (p < 0.001).

   Conclusion. Depressive disorders are the leading disorders in neurological patients, but their number and severity of symptoms are often ignored by specialists. Therefore, the health authorities are faced with the task of building a clinical and organizational algorithm for the identification of depressive disorders, as well as their timely medical correction.

Authors: Zorina I. G. , Sokolov V. D. , Makarova V. V.
Published: September 2024

Introduction. The health of children and adolescents is a criterion of their body’s relationship with the environment and is formed under the influence of a complex set of social, biological and environmental factors. Educational organizations are the only system of public education that covers the entire child and adolescent population of the country for a long period of time. Physical factors of the intra-school environment affect the physiological processes of the body of schoolchildren and ensure adaptation to physical exertion.

   The purpose of the study: to study and evaluate the physical factors of the educational environment in schools of the Chelyabinsk region in the dynamics of five years and the adaptive potential of students.

   Materials and methods. Statistical, mathematical and instrumental research methods are used in the work. The conditions of physical education classes in 10 schools in the cities of the Chelyabinsk region from 2018–2022 were studied and an assessment of physical performance was carried out in 102 students of grades 8–9. It was found that the largest share was accounted for by objects classified as medium risk and moderate risk in 2020–82.8 %.

   Results. The proportion of educational institutions that do not meet sanitary and hygienic standards in terms of artificial illumination and electromagnetic studies remained high and amounted to 14.2 % and 8.9%, respectively, excess air temperature was detected in 20 % of the studied schools. In 60 % of the schools studied, outdoor sports grounds have not been repaired since they were put into operation.

   Conclusion. 26.7 % of respondents showed satisfactory adaptation to physical exertion, 73.3 % (2.8 times more) of respondents noted the strain of adaptation mechanisms. The number of students with overweight and revealed stress of adaptation mechanisms was 66.7 %, and with a lack of body weight, this figure was 2.1 times less and amounted to 28.5 %. A third (33.3 %) of overweight respondents showed satisfactory adaptation, while underweight students showed 2.2 times higher (71.5 %).

Published: September 2024

Introduction. The increase in the number of diseases associated with malnutrition has reached global proportions and has become a serious problem for health systems around the world. For example, in the United States, about 36 % of the adult population is obese, in Russia, Georgia and the Republic of Belarus this figure ranges from 21% to 24%. Foreign experience (the Netherlands and the USA) illustrates that the population’s idea of proper nutrition is unrealistic: underestimation of high fat intake, low consumption of vegetables and fruits, etc., relative to their daily allowance, misconception in assessing the balance of their own diet, etc.

   The purpose of the study: to study the commitment of the population to proper nutrition and to determine the factors influencing people’s choice.

   Materials and methods. In this work, a questionnaire method was used using a developed questionnaire consisting of seven blocks and 46 questions. Statistical analysis of the data was carried out using the programs Statistica for Windows version 10.0 and R-studio.

   Results. 2,731 respondents over the age of 18 (45.7 % men and 54.3 % women) from all regions of the Russian Federation took part in the survey. Only 5 % (n = 136) replied that they constantly adhered to proper nutrition, a large proportion preferred not to do it at all (43.4 %, n = 1,186) and a third – from time to time (37.3 %, n = 1,018). In addition, it is important that 14.3 % of respondents (n = 391) found it difficult to answer the question, which is most likely due to a lack of understanding of what the concept of «proper nutrition» includes. The parameters related to the observance of proper nutrition by the respondents were female gender, high financial status and regular breakfast intake. In addition, non-smokers, as well as people who, when choosing food in the store, paid attention to the composition, calorie content and the inscription «GMO-free»/ «Sugar-free»/ «Healthy food», had a higher chance of adhering to a proper diet compared to the rest of the participants.

   Conclusion. It is necessary to increase the commitment and awareness of the population about proper nutrition, focusing primarily on men, obese people, low financial status, workers/employees/specialists, smokers, who often ate at night, ate semi-finished products at home, and ate everything that was on the plate to the end.
Inquiring Children’s Security within the Framework of Human Security: A Theoretical Assessment
Authors: Öztürk Zerrin Ayşe
Published: September 2024

ABSTRACT
While there is consensus on the individual as the primary referent object within the human security debate the question of which individuals? remains inadequately addressed. In this paper children are the primary referents and beneficiaries of security, arguing children’s human security possesses distinct characteristics that differentiate the nonviolent, preventable threats they face from those encountered by adults. Addressing these threats requires an integrated approach that combines theoretical exploration with practical policy implementation. The current academic discourse on human security, while extensive, must prioritize children’s specific needs by acknowledging them as key referents of security and essential subjects in both theory and practice. This involves recognizing children as active social and political agents, and addressing the unique dimensions of their vulnerability through comprehensive, targeted strategies. Achieving meaningful progress in safeguarding children’s security demands concerted efforts from all sectors, including researchers, policymakers, practitioners, and political leaders. Effective policy and practice require a collaborative approach that emphasizes the prevention and early identification of risks. Enhanced academic attention and robust discussions on children’s security are vital in shaping policies that reflect the urgency of these issues and drive effective interventions on a global scale.

Keywords: children’s security, children’s rights, child well-being, human security, critical security.

Authors: Ahumada Lerma Rafael Santiago
Published: September 2024

Las decisiones gerenciales son necesarias para darle rumbo a las empresas y más aún cuando estas entran en periodos de crisis financieras. Una herramienta clave para evaluar dichas decisiones son los costos pegajosos. El artículo discute la pegajosidad en las empresas listadas en la bolsa de valores de Colombia entre 1995 a 2022. Se examinan tres determinantes que pueden afectar la pegajosidad de los costos, la rotación de activos fijos, ROA y el ciclo medio de efectivo. Se utiliza una metodología cuantitativa, mediante una regresión múltiple y un modelo de datos panel. Se encontró que el 61,5% de las empresas analizadas adolecen de pegajosidad, debido primordialmente a la rotación de activos fijos. Se recomienda analizar otras compañías de menor tamaño, sabiendo que esto implica fortalecer bases de datos en Colombia. Como limitante el reporte de la información financiera no fue constante en las empresas. Esta investigación es pionera e innovadora en Colombia destacando la importancia de la gestión de la gerencia. Se concluye que es necesario seguir investigando en Colombia acerca de costos pegajosos utilizando otros determinantes.

Authors: Bayne David , Keefe Willow , Shune Samantha
Published: September 2024

Informal caregivers play a critical role in supporting individuals with dementia, yet often face significant challenges that impact their own quality of life (QoL). This exploratory study investigates the multifaceted factors contributing to caregiver QoL, particularly focusing on care recipient factors including dysphagia, dietary restriction, dementia severity, and care recipient QoL. A total of 24 informal caregivers of persons with dementia (PWD) participated in an online survey assessing various factors believed to play a role in caregiver QoL including dysphagia severity, dietary restrictiveness, cognitive impairment, and caregiver QoL. Results revealed that increased degree of dietary restrictiveness, lower dementia symptomatology, and higher care recipient QoL were significant predictors of improved caregiver QoL. These findings highlight the complex interplay of factors influencing caregiver QoL and underscore the need for tailored interventions to enhance well-being in both caregivers and care recipients within community-based care settings.

Published: September 2024

Charcot-Marie-Tooth disease is also called hereditary motor and sensory neuropathy. It is a genetically determined disease that has different variants of inheritance whose substratum is neuromuscular disorders. It may begin during childhood or later in life. Scientists have identified and described more than thirty genetic mutations that form an individual unique passport of violations of the sequence of a group of organic compounds or nucleotides in nucleic acid molecules. There are autosomal dominant, autosomal recessive and X-linked types of genetic inheritance of Charcot-Marie-Tooth disease. This pathology was first described in 1886 and affects about 10 to 40 per 100,000 population. More than 15,000 cases of Charcot-Marie-Tooth disease have been registered in Ukraine. It should be noted that peripheral myelin protein 22 became the first described gene causing Charcot-Marie-Tooth disease. Autosomal dominant Charcot-Marie-Tooth type 1 is the most common form of the disease. When observing patients, a neurologist pays attention to gait disturbances (steppage gait), foot distortion (pes cavus), distal hypotrophy, decrease or absence of tendon and periosteal reflexes, weakness and loss of sensitivity in the distal parts of the limbs. Hypotrophic changes in the limbs are continuously progressive. As a result of muscle atrophy and foot deformity, high-arched feet and extension of the big toe (Friedreich’s foot) are formed. To date, no pathogenetically substantiated treatment exists for Charcot-Marie-Tooth disease, but a multi-vector approach to comprehensive rehabilitation measures creates the necessary conditions to effectively control the manifestations of the inevitable progression of this pathology.

Authors: Lei Yin
Published: September 2024

The study investigates the implementation of the China Standards of English (CSE) Framework in China and its effect on students' English proficiency. The study, involving 250 students and 100 instructors, demonstrated that the execution of the CSE Framework is irregular and deficient, revealing inconsistencies between the prescribed standards and actual practices. The findings reveal an absence of significant link between the degree of CSE implementation and students' test performance, underscoring the disconnect between policy and practice. The results suggest that a more thorough and methodical application of the CSE Framework is crucial for enhancing English language proficiency outcomes among university students in China. The study concludes with recommendations for a comprehensive redesign of the curriculum and instructional methods to improve alignment with the CSE Framework and enhance student performance in English proficiency assessments.
Adaptive Financial Management and Teachers' Assessments of Resource Availability
Authors: Zhou Xinhuan
Published: September 2024

Adaptive financial management and teacher evaluation of resource availability are of vital significance in the sustainable development of educational institutions. Adaptive financial management is closely related to teachers’ evaluation of resources availability. In the education system, the adaptability of financial management directly determines the scale and type of resources that can be allocated to teachers. Effective financial management can accurately identify the resources needed for teacher evaluation. The lack of adaptability of financial management may lead to the shortage of teacher evaluation resources, affecting the comprehensiveness and accuracy of the evaluation, and thus unable to truly reflect the teaching level and contribution of teachers. There is an inherent logical connection between adaptive financial management and the availability of teacher evaluation resources. Reasonable financial management should adjust the allocation strategy of resources according to the objectives, requirements and scale of teacher evaluation. If financial management cannot meet this demand, there will be a shortage or waste of resources, which will affect the normal development of teacher evaluation.

ChatGPT is a chatbot with potential educational benefits, particularly in enhancing computational thinking (CT) proficiencies such as programming, debugging, and algorithmic thinking for students. Despite its promise, there is limited research on how ChatGPT can specifically support the integration of CT into mathematics education using tools like GeoGebra. The researchers implemented plugged-computational thinking in mathematics (Math+CT) lessons by means of the utilization of GeoGebra, an application that requires students to input commands in order to generate mathematical objects. The present investigation employed an educational design research (EDR) methodology in which the researchers incorporate ChatGPT into our Math+CT lessons to assist students in accomplishing the task. We purposely selected the participants who are mainly postgraduate students and collected data from the participants’ conversation with ChatGPT and recorded their screens while interacting with ChatGPT and our Math+CT task. We analyzed the data through descriptive qualitative method on the participants’ prompts, the final codes and the number of iterations. The researchers examined how ChatGPT could be utilized to assist the participants in writing GeoGebra commands in terms of its benefits and limitations. ChatGPT assisted most participants in completing the task successfully, with only a basic need for proficiency in GeoGebra commands, mathematics, and critical thinking. However, it revealed that participants did not yet utilize an affective prompt to ChatGPT. Furthermore, ChatGPT has the potential to be utilized for differentiated instruction due to the fact that its responses to individual users vary significantly based on the input prompts. Limited understanding of basic GeoGebra commands, and mathematical concepts could hinder the participants from training ChatGPT or prevent them from arguing with ChatGPT. This study enhances the existing literature by illustrating that ChatGPT can facilitate critical CT aspects, including programming and debugging, in a mathematics education context. This suggests that AI tools such as ChatGPT can contribute to the development of independent problem-solving skills, provide tailored support based on the needs of individual students, and enhance personalized learning experiences. Additional research involving students in school is required in order to gain a deeper understanding of the integration of ChatGPT into Math+CT lessons.

In solid geometry, the concept of conic sections plays an important role in teaching graphs such as parabolas, ellipses, and hyperbolas to undergraduate students in Mathematics Education. It is understood that the abstraction process in mastering conic sections is strongly needed. This study examines the abstraction process of conic sections among third-year undergraduate Mathematics Education students (4 males and 21 females) at Universitas Muhammadiyah Malang (UMM), Indonesia. The data was collected by analyzing students' responses in a 60-minute diagnostic test using the Abstraction in Context (AiC) framework. The test consists of 3 questions, validated by 2 Professors of UMM (average score = 4.14) and 2 lecturers (average score = 4.04). The results showed that 1 male and 11 female students did not reach the construction stage of AiC. Subsequently, a student with a low diagnostic test score and the least completion of AiC stages was observed further through an interview. This student passed through all stages of abstraction with the help of DGE. We also underscored undergraduates' challenges in this process, particularly in visualizing conic section objects, spatial thinking, and employing appropriate mathematical signs. Based on these findings, further research with a broader sample is needed to explore diverse abstraction processes.

Analogical thinking is a crucial strategy for mathematical problem-solving, enabling the discovery of solutions by identifying similarities between different problems. However, existing research needs a comprehensive classification of students' use of analogical thinking in this context. This study aims to develop a new classification framework for analogical thinking in mathematical problem-solving, emphasizing the identification and utilization of analogous methods between source and target problems. The research adopts a descriptive qualitative approach involving a purposive sample of 15 high school students from Surakarta, Central Java, who demonstrated analogical thinking in solving both source and target problems. Data collection was conducted through tests, observations, and interviews, with analysis performed using the constant comparative procedure (CCP). The findings reveal three distinct classifications of analogical thinking: pattern recognition (identifying common patterns to solve both source and target problems), variable utilization (using variables as symbolic tools for problem-solving), and visualization (applying graphical representations to address the issues). This study offers significant theoretical insights for future research and practical implications for applying analogical thinking in enhancing mathematical problem-solving.

This study examines the outcomes of implementing a teaching unit that integrates problem-solving with the history of mathematics to improve fifth-grade students' understanding of fractions at an educational institution in Yopal, Colombia. Utilizing an educational action research methodology, the study commenced with a diagnostic assessment to identify learning gaps, followed by the design and implementation of a didactic unit. This unit comprised three activities embedded in historical contexts to facilitate the learning of fractions, with its effectiveness assessed through an exit test. Conducted with 32 fifth-grade students, the research employed diagnostic and exit tests to evaluate student performance before and after the activities. The results demonstrated that the teaching unit significantly enhanced students' abilities to understand and apply fractions, as evidenced by their improved performance in the activities within the didactic unit.

While previous studies have extensively explored ethnomathematics, the relationship between ethnomathematics and ethnomodeling remains underexamined. This study investigates the connections between ethnomathematics and ethnomodeling and their implications for the institutionalization of mathematics in the context of traditional fish auction activities within the Fishermen's Community in Indramayu, Indonesia. Utilizing an ethnographic design, the study involved participants in various auction roles, including auctioneers, boat owners, captains, crew members, and traders. Data were collected through interviews and observations and analyzed using content analysis. The findings reveal that ethnomathematical practices are evident in sorting and grading fish, as well as in auction transactions, with connections to mathematical concepts such as set theory, basic statistics, social arithmetic, and arithmetic operations within an ethnomodeling framework. These results suggest that the integration of ethnomathematics and ethnomodeling into the school curriculum could support the institutionalization of mathematics education and provide a foundation for developing instructional materials based on these practices in the context of traditional fish auctions.

Mental strategies are recognized as an effective approach for solving arithmetic operations such as addition and subtraction. This study focuses on developing and implementing instructional activities aimed at enhancing students' mental strategy skills through the Indonesian Realistic Mathematics Education (IRME) approach. The research employed a design-based methodology involving 2nd-grade students from an Islamic-integrated school in Surabaya. The study followed a research design that emphasizes the development of local instructional theory, encompassing three key phases: the preparatory phase (initial design development), the experimental phase (classroom teaching experiments), and the retrospective analysis phase. Data collection methods included documentation, field notes, and interviews. In the first trial, three instructional activities were conducted. Based on the analysis of the first trial, the number of activities in the second trial was increased to four: "Let's Get Used to Alms Every Day," "Don't Forget Routine Alms This Week," "Set Your Own Pocket Money," and "Let's Give Away Your Alms to Break Mr. Samad’s Fast." These activities were designed to achieve specific mathematical objectives, enabling students to understand and solve addition and subtraction problems using strategies such as skip counting, borrowing, and saving. The retrospective analysis concluded that students successfully learned to perform addition and subtraction operations on both monetary values and ordinary numbers within the designed learning trajectory.
