Authors: Piedra Andrés Benavides , Reascos Irving
Published: September 2024

Audiovisual materials have been widely investigated in mathematics education for their capacity to improve learning outcomes and mitigate student disengagement. Therefore, this study aims to evaluate the acceptance of audiovisual materials as instructional aids among eighth-grade students. Adopting a mixed-method approach, the research first involved semi-structured interviews with mathematics teachers to identify key teaching and learning challenges. Based on the insights gained, educational videos were developed, adhering to motivational and didactic criteria. In the final phase, 78 students from a public high school in Ibarra, Ecuador, participated in a Likert-scale survey, guided by the Technology Acceptance Model (TAM), to assess their reception of the videos. The findings revealed that teachers highlighted fear of mathematics, insufficient prior knowledge, and the abstract nature of the content as major obstacles to be addressed. Most students responded positively, considering the videos effective for enhancing their understanding of mathematical concepts and boosting their motivation to learn. This study underscores the potential of audiovisual materials as effective tools to address educational challenges and foster student engagement in mathematics.

Published: September 2024

This study addresses the pressing need to develop critical thinking skills in young learners, which is essential for 21st-century education. Focusing on Indonesian elementary school mathematics teachers, this research provides new insights into the specific challenges they encounter a context that has been underexplored in the existing literature. The primary objective of this study is to identify the barriers these teachers face when integrating critical thinking skills into their mathematics instruction. Utilizing a qualitative approach, the research employs open-ended online surveys, allowing participants to respond to their own words rather than selecting from predefined options. Convenience sampling was used to recruit participants, resulting in a sample of 114 teachers from ten provinces across Indonesia. Data from the surveys were analyzed thematically and inductively using constant comparative methods. The analysis identified that the major obstacles to integrating critical thinking skills into mathematics education were limitations related to time and resources (accounting for 71.34% of identified barriers), along with deficiencies in pedagogical knowledge, confidence, and skepticism about the expected outcomes. The findings of this study offer valuable insights into the considerations necessary for successfully incorporating critical thinking skills into elementary mathematics instruction and highlight the potential for enhancing teacher effectiveness in this area.

Published: September 2024

Polyhedrons present a challenging topic in elementary geometry education. The Indonesian Realistic Mathematics Education (IRME) approach, when contextualized within the Bukit Sulap tourism area, offers a promising solution to this challenge. This study aims to design a learning trajectory for teaching the surface area of polyhedron using IRME in the context of Bukit Sulap tourism. Employing a research design with a validation study type, the study was conducted in three phases: preparation and design, experimental teaching, and retrospective analysis. The participants were 27 elementary school students from Lubuklinggau City, Indonesia. Data collection instruments included surface area problem-solving worksheets, video recordings of in-depth learning interviews, field notes, and observation sheets. The findings suggest that the Bukit Sulap tourism context significantly enhanced students' understanding of surface area problems, specifically those involving combinations of cuboids and cubes. Additionally, IRME effectively facilitated students' comprehension of abstract mathematical concepts, particularly the surface area formulas for cubes and cuboids. The study concludes that using the Bukit Sulap tourism park context as a starting point for teaching the surface area of polyhedron aligns well with the principles of IRME.

Authors: Mengyao He , Ismail Zaleha , Ismail Norulhuda , Xueting He
Published: September 2024

Motivation plays a crucial role in enhancing students' achievement in mathematics, as motivated students are more likely to engage actively with the subject. However, in China, there is a concerning trend of declining motivation among students toward mathematics, with many exhibiting avoidance behaviors. Despite Ningbo's significance as a major city in China, there is a lack of studies and surveys addressing students' motivation in mathematics learning. This study addresses this gap by employing a questionnaire based on Keller’s ARCS (Attention, Relevance, Confidence, Satisfaction) model, which has been proven effective in measuring students’ motivation. The survey, conducted among 384 high school students in Ningbo, China, aimed to assess their motivation levels in mathematics learning. Descriptive statistical analysis was performed using SPSS Statistics 29 to calculate the mean and percentage for each item. The results revealed that the motivation level among high school students in Ningbo is notably low. Two significant factors contributing to this low motivation were identified: students’ lack of confidence due to the perceived difficulty of mathematics and the belief that mathematics is not closely related to real life.
Investigating the effect of manipulatives on mathematics achievement: The role of concrete and virtual manipulatives for diverse achievement level groups
Authors: Ahmad Sagheer , Siller Hans-Stefan
Published: September 2024

This study investigates the impact of integrating both concrete and virtual manipulatives on the mathematics achievement of fifth-grade students across different achievement levels (low, average, and high). Utilizing a quasi-experimental design with pre- and post-tests, a convenience sample of fifth-grade students was randomly assigned to either a control or experimental group. The data collection instruments, consisting of separate pre- and post-tests on the same mathematical concepts, underwent thorough validity and reliability testing. Initial assessments demonstrated that the achievement levels between the control and experimental groups were comparable prior to the intervention. The experimental group received instruction that incorporated both concrete and virtual manipulatives, whereas the control group followed traditional teaching methods. Following a 12-week intervention period, a post-test was administered. The data were analyzed using parametric paired-sample t-tests and one-way ANCOVA, ensuring that all underlying assumptions were satisfied. The findings revealed significant improvements in post-test scores among students in the experimental group, regardless of their initial achievement levels. Although low-achieving students in the control group also showed progress, their gains were less substantial compared to those in the experimental group. This study highlights the potential benefits of incorporating both concrete and virtual manipulatives in fifth-grade mathematics instruction to enhance academic achievement.

‘Demographic’ factor of fertility: Assessing territorial potential on the example of the Nizhny Novgorod region
Authors: Egorova Nadezhda , Sitnikova Irina
Published: September 2024

Introduction. Despite the implementation of serious measures in the framework of state family policy to stabilise the demographic situation, it remains difficult in most regions. This is due, firstly, to the new challenges the country is facing, and secondly, to the complexity of the very processes that need to be controlled. Population size, being a complex quantitative indicator of the stability of society, is determined by a number of demographic processes, among which fertility remains the main one. The number of studies attempting to identify the factors determining fertility trends is growing. All of them demonstrate the complexity and multifactorial nature of the process and the changes taking place. More and more often attention is paid to the demographic characteristics (sex-age and marriage structure) of the population as a starting point from which to begin the assessment of the territory and its reproductive potential.

Nizhny Novgorod region, being a typical Russian region, has been demonstrating an unfavourable scenario of demographic situation development in recent decades. The article attempts to describe and assess the reproductive potential of the region, to identify the possibilities and limitations of fertility growth in the current conditions, based on the analysis of the ‘demographic’ factor.

Materials and methods. The analysis and conclusions are based on the data of the Federal State Statistics Service on demographic processes in Russia and the region for 1990-2023 (population size, birth rate, marriage rate, divorce rate), as well as on the data of regional sociological studies on fertility and family/reproductive behaviour.

Results and discussion. The results of the study provide little basis for a favourable forecast in the region. On the one hand, the sex and age structure of the population is not yet characterised by disproportion in fertile ages, except for the oldest groups. However, there is a high probability of its appearance in younger ages under current conditions. In addition, active and potential fertile groups of women are significantly smaller than older groups. The marriage structure is becoming more stable, but with a high probability of divorce, acceptability of cohabitation, and a shift of births to older groups. The studies record a persistent gap between the desired and actual number of children in different socio-demographic groups, which, from the authors' point of view, is important and requires careful research to correctly stimulate fertility.

Authors: Moreno Navarro Ángel , Martínez Ortega Ma. de los Ángeles , Martínez Ortega Minerva
Published: September 2024

En los inicios de la Ciudad de México (CDMX) su configuración territorial fue delimitada por elementos físicos naturales o por el señalamiento limítrofe a través de mojoneras, las cuales son monolitos de piedra. Con el crecimiento poblacional, la gente se fue estableciendo en los límites de la CDMX modificando la configuración territorial planeada en los inicios de esta. Existen por otro lado, factores políticos como la configuración de los distritos electorales que generaron otro nuevo límite, esto trajo problemas graves a la población ya que se presentó una dualidad en su delimitación y definición territorial, (por un lado, ser de la CDMX y por otro del Estado de México). Se partió del supuesto hipotético que la falta de claridad en la delimitación territorial de algunas comunidades y la conformación de los distritos electorales por el Instituto Nacional Electoral (INE), generaron una doble división política.  El objetivo de este trabajo fue identificar la importancia de la aplicación de la planeación urbana y de una clara delimitación territorial, a través de la detección de mojoneras. Además del señalamiento del impacto provocado en la comunidad estudiada, así como algunas condiciones que repercutieron directamente.
Esta investigación es mixta (cuantitativo-cualitativa) por un lado se realizó la identificación de los límites territoriales definidos en la “Ley del Territorio de la CDMX” a través de la ubicación de las mojoneras, contrastando con los límites de la cartografía del padrón electoral del INE, mostrando una dualidad territorial, tal y como se señaló en la hipótesis. Una vez encontrada la diferencia, se pudieron mostrar algunas consecuencias muy negativas para la población estudiada. Se detectó que los predios afectados por esta dualidad, presentan problemas puntuales al no contar con los servicios básicos; así como, de identidad, al estar en los límites de una alcaldía y un municipio a nivel estatal.

Published: October 2024

Inclusiveness of people with disabilities is a global issue related to equal rights and opportunities for active participation. The art of gesture photography is a medium to realize this. So, how to make it happen? Using descriptive qualitative research methods and an ethnographic approach, as well as the implementation model of Van Meter and Van Horn as the basis for data analysis. The results of the research show that there is quite a lot of potential for photography artists with disabilities in Indonesia, the absence of a specific policy has resulted in less than optimal implementation. The mistake of forming the KND, which was non-structural and independent, was to make it part of the Ministry of Social Affairs. The government needs to involve people with disabilities in making policies and not only focus disability issues on social issues, but more broadly on human rights issues.

The impact of industry structure on the value of national logistics costs/gross domestic product: Evidence from China
Authors: Zhang Zhaomin , Li Yanhua
Published: September 2024

The proportion of national logistics costs to Gross Domestic Product (NLC/GDP) serve as a valuable indicator for estimating a country’s overall macro-level logistics costs. In some developing nations, policies aimed at reducing the NLC/GDP ratio have been elevated to the national agenda. Nevertheless, there is a paucity of research examining the variables that can determine this ratio. The purpose of this paper is to offer a scientific approach for investigating the primary determinants of the NLC/GDP and to advice policy for the reduction of macro-level logistics costs. This paper presents a systematic framework for identifying the essential criteria for lowering the NLC/GDP score and employs co-integration analysis and error correction models to evaluate the impact of industrial structure, logistics commodity value, and logistics supply scale on NLC/GDP using time series data from 1991 to 2022 in China. The findings suggest that the industrial structure is the primary factor influencing logistics demand and a significant determinant of the value of NLC/GDP. Whether assessing long-term or short-term effects, the industrial structure has a substantial impact on NLC/GDP compared to logistics supply scale and logistics commodity value. The research offers two policy implications: firstly, the goals of reducing NLC/GDP and boosting the logistics industry’s GDP are inherently incompatible; it is not feasible to simultaneously enhance the logistics industry’s GDP and decrease the macro logistics cost. Secondly, if China aims to lower its macro-level logistics costs, it must make corresponding adjustments to its industrial structure.

Published: September 2024

Despite its leading role in the urban transport system, paratransit is accused of being unsustainable and hostile to modernity. The reform of the sector is necessary in the context of the modernization of the transport system of African cities. It requires the formalization of actors through technical and financial support such as fleet renewal projects. This article attempts to analyze the financing process and the level of formalism of the operators constituted within the AFTU in the context of the financing operation of paratransit operators in Dakar, Senegal. The methodological approach adopted is based on the analysis of qualitative data from questionnaire surveys carried out in the AFTU network in Dakar; official documents1 were also used. The results show that the Dakar financing model put in place has made it possible to make significant progress in the reorganization of paratransit professionals. In addition to the concessioned lines, a salaried system was introduced, pricing is now official and the standardized ticketing system has been put in place. Nevertheless, improvements are expected on the working conditions of employees, the capacity building of actors and the evolution of the legal status of companies.

Published: October 2024

As an important cultural institution for urban cultural inheritance and construction, the complementarity, interaction, and development between university culture and urban culture are also getting more and more attention. This study analyzes the dynamic mechanism of the integration of university culture and urban culture by combining the dynamics model. Then, it constructs a dynamics model for the integration of urban culture into university culture based on the group dynamics theory and the airplane dynamics model. Then, a data-driven decision-making optimization scheme is proposed based on the BASM model, and a data-driven decision-making model oriented to the development of cultural integration is constructed with the data related to the artistic integration of universities as the driving basis. Finally, an empirical analysis of the integration development of culture between University M culture and Guangzhou city culture is carried out in Guangzhou city as an example, with a comprehensive average score of 92.70 for cultural recognition, and the correlation coefficients of the dimensions are highly correlated between 0.812 and 0.891. Meanwhile, the regression coefficients corresponding to the seven dimensions of cultural integration and development are all less than 0.05, and the VIF values are all less than 10. Moreover, the comprehensive average score of each dimension after optimization is 4.193, which is 0.79 points higher compared with that before optimization, and the satisfaction level is 1.297 points higher. In this paper, the optimization of the development strategy for the integration of university culture and urban culture can promote cultural integration and provide a specific optimization path for the integration of university culture and urban culture.

Published: October 2024

Currently, the implementation of a coal mine production safety monitoring system, capable of real-time monitoring of the safety condition of large coal mine equipment and timely dispatch management, is crucial for the efficient and safe operation of coal mine enterprises. This paper designs the coal mine major equipment failure process based on the rolling bearing’s vibration mechanism, analyzes the major equipment’s failure signal using both time domain and frequency domain analysis methods, and employs the intelligent fuzzy control method to identify the major equipment failure. We have designed and practically applied a real-time, multi-threaded, and comprehensive fault diagnosis and prediction system for coal mine major equipment, combining information from coal mine safety, production, and operation. The results show that the normal state’s time-domain amplitude approximates (-0.2, 0.2), and the time-domain waveforms all display periodic shock signals when the bearing sustains damage. The faulty vibration amplitude of the inner ring is within 0.08 ms
2 and the faulty vibration amplitude of the outer ring is within 0.44 ms
2, and the diagnostic accuracy using the method of this paper reaches 97.2%. This study demonstrates the effectiveness of remote monitoring and fault analysis of major equipment in coal mines, which effectively improves the equipment start-up rate and ensures coal mine production safety.

This paper analyzes the engineering characteristics of loess and the factors affecting wet subsidence, briefly outlines the application effect of PP modular cisterns, and combines the two to design a PP modular cistern based on rainwater harvesting. Combined with the analysis of the pre-engineering conditions of the storage tank, propose the treatment method for wet subsidence loess foundations. Design the structure of the storage tank by determining the volume of the tank by comparing the difference between the inlet and outlet flow during the storage time integral. Simulate the modeling of storm floods and the process of emptying stormwater regulating ponds. Evaluate the geologic conditions for the construction of the regulating pond project. Compare the original investigation report with the results of this paper’s test of the engineering foundation’s wet subsidence coefficient. Set different thicknesses of bedding layers and calculate the settlement of the center of the pool under different humidity levels of the loess layer. Simulate the 2.3-hour rainstorm process, analyze the storage volume of the storage pond during the period, and calculate the cumulative storage volume of the storage pond. This project’s foundation loess wet subsidence coefficient is medium, and the actual additional pressure is much smaller than the starting pressure of wet subsidence. It is appropriate to use the soil bedding program (1.6m plain soil bedding layer and then rammed 0.4m thick 2:8 gray soil, with PP module seepage control). Combined with the local hydrological conditions, it is known that the peak present time of the peak outflow from the regulating pond T

Authors: Hamed Zena Sattam , Shaban Khalid Ahmed , Faris Ghada Abdul-Munem
Published: October 2024

Combining analgesic medications with distinct pharmacodynamics may result in effective analgesia and reduced adverse effects by lowering dosages of one or both medications. The objective was to investigate the nature of interactions of metoclopramide and metamizole by measuring the antinociceptive and neurobehavioral effects in mice. The drugs were administered intraperitoneally (ip) in mice. The antinociceptive effect was determined by the up-and-down method. Isobolographic analysis was performed by simultaneous injection of the two drugs at ED50 ratios of 1:1 and 0.5:0.5. The treated mice were also subjected to an open-field behavioral test as well as dorsal immobility and negative geotaxis behavioral paradigms. The ED50 of metoclopramide and metamizole were 33.71 and 43 mg/kg ip, respectively. Lower ED50 was established for metoclopramide and metamizole by 48.44% and 47.49%, respectively when given at a ratio of 0.5:0.5, and by 35.81% and 29.88%, respectively at a ratio of 1:1. The combined dose of metoclopramide and metamizole (8 and 10 mg/kg, ip, respectively) significantly decreased the open field-activity test in mice. This was observed by lower number of squares crossing compared to the control. Additionally, the drug combination resulted in a substantial increase in the duration of dorsal immobility response and delayed the negative geotaxis task when compared with the control group. The results indicated that the interaction between metoclopramide and metamizole in lower dose ratio with ED50 50:50, was synergistic in producing analgesia in mice with reduced risk for adverse reaction but with decreased behavioral and motor neuronal activity.

Published: October 2024

Periodontal disease is a global prevalent burden on well-being and health-related quality of life. Adequate plaque control on a daily routine basis is the most critical thing to achieve periodontal health. Using toothbrushes in combination with dentifrices is one of the most common methods of oral hygiene maintenance. However, natural chewing sticks such as Salvadora persica are still used in many developing countries due to their low cost and religious background. Salvadora persica displays precious biotherapeutics capacity for antimicrobial, antiviral, antioxidant, and anti-inflammatory effects. Recently, a lot of Salvadora persica extract has been found in dentifrices, mouthwash, chewing Gum, and even local delivery drugs such as periodontal chips, which are still in the research stage. The present review aims to summarize the evidence of various pharmacological and therapeutic aspects of the effectiveness of Salvadora persica in promoting periodontal health and the treatment of periodontal disease.
The Role of Streptococcus mutans Virulence Proteins in the Pathogenesis of Endocarditis: Mechanisms of Action and Impact on Heart Infections, A Review
Authors: Winato Brigad Mahardika , Mylano Tri Adi
Published: October 2024

Background: Streptococcus mutans, known for causing dental caries, can also lead to endocarditis, a severe heart infection involving inflammation of the heart's inner lining and valves. This study focuses on the virulence proteins of Streptococcus mutans and their role in endocarditis pathogenesis. Objective: To investigate the mechanisms of action of Streptococcus mutans virulence proteins and their impact on the development of endocarditis. Methods: A comprehensive literature review focused on the virulence factors of Streptococcus mutans, such as Glucosyltransferases (Gtf), Adhesin P1 (Antigen I/II), Dextranase, and proteolytic enzymes. The role of these proteins in bacterial adhesion, biofilm formation, and tissue invasion was analyzed. Results: Glucosyltransferases facilitate biofilm formation by synthesizing sticky glucans from sucrose, protecting bacteria, and aiding the colonization of heart valves. Adhesin P1 enables bacterial attachment to host tissues, which is crucial for initial colonization. Dextranase modifies biofilm structure, enhancing stability and resistance. Proteolytic enzymes degrade host proteins, aiding bacterial invasion and causing tissue damage. Conclusion: Streptococcus mutans employ multiple virulence proteins to adhere to, colonize, and invade heart tissues, leading to endocarditis. Understanding these mechanisms is essential for developing preventive and therapeutic strategies against this severe infection.

Authors: Gani Azhari , Hayati Kemala
Published: October 2024

Background: Myocardial infarction (MI) and hypertension are cardiovascular conditions that frequently coexist and influence each other. Hypertension not only increases the risk of MI but also complicates its clinical management. Therefore, it is crucial to understand the complications arising from this condition and the effective management strategies. Objectives: This systematic review aims to identify and analyze common complications in hypertensive patients experiencing MI and evaluate the optimal management approaches based on the latest literature. Methods: A literature search was conducted in electronic databases such as PubMed, Scopus, and Google Scholar using relevant keywords like "myocardial infarction," "hypertension," "complications," and "management." Articles published in the last five years were selected to ensure the most current information. Inclusion criteria included observational studies, clinical trials, and systematic reviews relevant to the topic. Data were extracted and analyzed descriptively. Results: Of the 1500 articles identified, 45 studies met the inclusion criteria. Major complications found in hypertensive patients with MI included heart failure, arrhythmias, stroke, and left ventricular dysfunction. The most effective management approaches included appropriate use of antihypertensive medications, early reperfusion interventions, and a multidisciplinary approach to controlling cardiovascular risk factors. The use of ACE inhibitors, beta-blockers, and aldosterone antagonists proved to have significant benefits in reducing morbidity and mortality. Conclusions: Complications of myocardial infarction in hypertensive patients require comprehensive and coordinated management. Effective management involves a combination of pharmacological and non-pharmacological therapies focusing on optimal blood pressure control and prevention of further complications. Further research is needed to explore more specific and personalized management strategies in this population.

Background: Root canal treatment is an effort to maintain the function and aesthetics of teeth. The smear layer is formed from the remains of instrumentation composed of organic and inorganic components. A smear layer in the tooth root canal will benefit the adhesion and colonization of microorganisms, block the action of disinfectant solutions, and prevent medicaments in the tooth root canal from penetrating the dentin tubules in the tooth root canal walls. Irrigation can be used for cleaning and disinfection in areas of the root canal that cannot be reached using instruments. Starfruit contains alkoloids, saponins, tannins, flavonoids, phenols, and triterpenoids. Objective: To determine the effectiveness of star fruit extract (Averrhoa bilimbi  L) as a smear layer cleaning agent. Materials and Methods: This researcher used laboratory or experimental testing called Post Test Only Control Design. Samples were taken using the purposive sampling technique involving four treatments and six repetitions. The statistical test used is the Mann-Whiteney test. Results: Based on the Mann-Whiteney test, the test results obtained a p-value of 0.093 which is more significant than 0.05 (p-value 0.05). The results showed no significant difference between the 17% EDTA and 35% extract treatment groups regarding smear layer cleanliness. The 35% extract group is as good as the 17% EDTA group. Conclusion:  star fruit extract (Averrhoa bilimbi  L) is 35% effective in cleaning the smear layer.
