Facilitating the retention of higher-order thinking skills in mathematics through Minecraft-based learning
Authors: Tangkui Rayner
Published: December 2024

There is a growing need for students not only to develop higher-order thinking skills (HOTS) but also to retain them. Retaining HOTS enables students to effectively apply these skills when needed, particularly in solving complex problems in subjects like mathematics. However, many students struggle to retain these skills due to the prevalence of conventional teaching methods in classrooms. Therefore, this research aims to examine the impact of Minecraft-based learning in mathematics on the retention of HOTS. Using purposive sampling, 33 Year 5 primary school students from a single intact class were selected as participants. A test comprising 15 multiple-choice questions served as the research instrument, administered during the pretest, posttest, and delayed posttest. The data collected were analyzed using a one-way repeated measures ANOVA. The findings revealed that learning mathematics through Minecraft, a sandbox-style digital game set in an open world, significantly improved students' learning outcomes in both immediate and delayed assessments compared to their pre-assessment performance. Notably, the HOTS domain of analyzing showed the greatest improvement. These results suggest that incorporating Minecraft into mathematics instruction is particularly effective in enhancing and retaining HOTS.

The learning process would be effectively when supported by various planning, including the use and utilization of instructional media. Instructional media were employed to facilitate the process of understanding information and convey learning messages. Identifying the appropriate instructional media can influence the achievement of the teaching and learning process. SMP Alquraniyah Nurul Huda Martapura was a school unit that is relatively newly established, and thus, the teaching and learning process still requires methods that can support students' progress. The main issues identified in this community service activity were: 1) a lack of utilization of digital technology in delivering learning materials in the classroom, 2) the teaching process mostly relies on conventional methods, and 3) the English language background of the partners was weak. In addressing these challenges, the wrtiter utilized digital comic media, which considered more engaging for students due to its colorful and attractive visuals. The results achieved in this community service activity include a significant improvement in the reading skills of SMP Alquraniyah Nurul Huda students, as evidenced by their reading practice results after several days of learning to read Narrative Text using Digital Comic Media.

This Community Service Practice focuses on improving the quality of management of the Al-Quran Education Park (TPA) in Pandansari Village, Sine District, Ngawi Regency, East Java. Even though there are several TPAs ??in Pandansari, there are TPAs ??that are less effective in managing and complying with the curriculum of the Al-Qur'an Kindergarten Development and Development Institute-Indonesian Mosque Youth and Youth Communication Agency (LPPTKA-BKPRMI) thus having an impact on the quality of education management Al-Qur'an. This research aims to improve landfill management through a comprehensive training program. This training equips educators with the tools and knowledge to align with the curriculum. So that it can increase the effectiveness of teaching at the Al-Quran Education Park. After the training, a Follow-up Plan (RTL) was carried out including distributing guidebooks and administration. Assistance in implementing the Curriculum of the Al-Qur'an Kindergarten Development and Development Institute-Indonesian Mosque Youth Communication Agency (LPPTKA-BKPRMI) has gone well. The socialization and distribution of all Guidebooks and Administration has been well distributed. All Al-Quran Education Parks in Pandansari Village accept and are willing to implement it in their respective Al-Quran Education Parks (TPA). However, some TPAs ??only accept some. Like TPA Baitul Hasyim, it is ready to implement a Cash Administration Book. And the Kholid Hasyim TPA has almost been completely implemented, only the Cash Administration Book has not been accepted. This research shows the importance of systematic management in improving Islamic education and suggests that further support and monitoring is needed for continuous quality improvement.

True Costing in Logistics & Supply Chain Management: How do we make decisions based on True Economic Trade-Offs (T-ETOs)?
Authors: Jansen Jan
Published: December 2024

Decision-making in logistics (including /supply chain management) is often based on traditional cost-price information from a company's accounting department. Externalities, like social and environmental impact, are usually not included in decision-making. To include a more integrated trade-off, the cost-price information should include information on the traditional costs and the costs of externalities like fair wages (social costs) and costs of damage, pollution, etc. (environmental costs). The article provides an overview of traditional costs and attempts to monetise externalities (by using the concept of shadow prices and the Lagrange multiplier or λ) as a base for decision-making in logistics. Some case studies are presented from the last decade and an example of a true economic trade-off for buying a diesel truck-tractor or an electric truck-tractor. In the previous example, much decision data is missing because no track record has yet been developed in this industry. The key issue is making external effects measurable so that business practices can make sound decisions based on financial, social, and environmental data.
The author ends the contribution with a call for further (applied) research into true pricing in logistics.

Emulator-based Bayesian calibration of a subglacial drainage model
Authors: Hill Tim , Flowers Gwenn , Bingham Derek , Hoffman Matthew
Published: December 2024

Subglacial drainage models, often motivated by the relationship between hydrology and ice flow, sensitively depend on numerous unconstrained parameters. We explore using borehole water-pressure timeseries to calibrate the uncertain parameters of a popular subglacial drainage model, taking a Bayesian perspective to quantify the uncertainty in parameter estimates and in the calibrated model predictions. To reduce the computation time associated with Markov Chain Monte Carlo sampling, we construct a fast Gaussian process emulator to stand in for the subglacial drainage model. We first carry out a calibration experiment using synthetic observations consisting of model simulations with hidden parameter values as a demonstration of the method. Using real borehole water pressures measured in western Greenland, we find meaningful constraints on four of the eight model parameters and a factor-of-three reduction in uncertainty of the calibrated model predictions. These experiments illustrate Gaussian process-based Bayesian inference as a useful tool for calibration and uncertainty quantification of complex glaciological models using field data. However, significant differences between the calibrated model and the borehole data suggest that structural limitations of the model, rather than poorly constrained parameters or computational cost, remain the most important constraint on subglacial drainage modelling.

Authors: Biswas Sandipa
Published: December 2024

Abortion being one of the most controversial issue carries with it a religious dogmatism, religious conflicts along with social, economic and political aspects. Religious dogmatism contributes to the abortion stigma that women may face when seeking or obtaining an abortion. These norms can manifest in a variety of ways that may limit access to safe abortion. This paper tries to explore those ways and manners which generally prevents the issue of abortion from nearing to logical thoughts and justifications. The paper also tries to analyse the relations and the ways by which these social stigmas and religious dogmatism gets attached to abortion which mostly yields unethical and negative consequences along with hampering the mental development of both the genders. Lastly the paper tries to highlight the religious conflicts prevailing in the Golokganj and Mayarchar areas of Dhubri District and tries to analyse the practical and ethical views of the whole matter and also attempts to bring an amicable solution so that our societies try to free themselves from the dogmatic religious norms of abortion and takes up the issue in a more rational and pragmatic manner for the much needed upgradation of the society.

18. yüzyılda Fas’ın sosyal, kültürel ve siyasi yapısı üzerinde Mevlây İsmâîl b. Muhammed eş-Şerîf el-Hasenî el-Alevî (ö. 1139/1727) ve oğulları etkili olmuştur. Ülkeyi önce Mevlây İsmâîl b. Muhammed ve sonrasında ise oğulları yönetmiştir. Onun ölümünden sonra oğulları arasında büyük taht kavgaları olmuş, bunun neticesinde ülke yıllarca süren bir istikrarsızlığa sürüklenmiştir. Bu kavgalar; bölgeyi, otuz iki yıl süren bir kargaşanın hüküm sürdüğü ve merkezi otoritenin zayıfladığı bir döneme sokmuştur. Bu çekişmelerin ardından bölge, ancak Mevlây İsmail’in torunu Muhammed b. Abdullah’ın (ö. 1204/1790) tahta çıkması ile (1170/1757-1204/1790) tekrar huzur ve güvene kavuşabilmiştir. Mevlây İsmâîl b. Muhammed döneminde sosyal, kültürel ve siyasi yönden en rahat günlerini yaşayan Fas, bu dönemde ilmî ve kültürel bir gelişme göstermiştir. Birçok ilmi konuda temâyüz etmiş çok sayıda ilim adamı dinî konulardaki çalışmalarının yanında Arap dili ve edebiyatı ile ilgili de çok sayıda eser telif etmişlerdir. Bu dönemin meşhur üç ilim adamından birisi kabul edilen ve dönemin edebî tanığı İbnu’t-Tayyib eş-Şerakî; dil, edebiyat ve dinî ilimlerde temâyüz ederek dinî ilimler, dil ilimleri, edebî ilimler, biyografi ve muhtelif alanlarda 61 eser telif etmiştir. Bu eserlerden 11’i günümüze kadar ulaşmış, 50 eseri ise kayıp hükmündedir. Eserlerini şerh, hâşiye ve talîk türlerinde kaleme almış olan Şerakî’nin verdiği eserlerin çoğunluğunu dil ve edebî ilimler oluşturmaktadır. Onun ilmî hayatı üzerinde dönemin siyâsi, sosyal, ilmi ve kültürel hayatının etkisinin büyük olduğu bir gerçektir. En büyük etkiyi de huzur dönemi olarak ifade edilen Mevlây İsmail’in yönetimi ile kargaşanın hâkim olduğu oğulları arasındaki taht kavgalarının yaşandığı dönemin siyâsi koşulları bırakmıştır. Çalışmada İbnu’t-Tayyib eş-Şerakî’nin Fas dönemi ilmî ve edebî hayatı ele alınmıştır. Bu çerçevede sadece dönemin ilmî ve edebî hayatı üzerinde durularak onun dönemin edebî ve ilmî hayatındaki yeri ve önemi tespit edilmeye çalışılmıştır.

Authors: Zaiats S.V. , Rozhko M.M.
Published: December 2024

The severity of changes in local hemodynamics makes it possible to assess the severity of the pathological process and the effectiveness of the treatment of the disease.
The aim of the study was to analyze the effectiveness of complex treatment of patients with generalized periodontitis II, II-III stage of development by using the enamel matrix protein drug "Emdogain" and the APRF technique.
Materials and methods. 65 people aged 34-59 years with a diagnosis of generalized periodontitis (GP) II, II-III degrees took part in the study. Depending on the method of treatment, patients were divided into four groups. Rheographic studies were carried out using the rheographic computer complex "RHEOTEST" DXSystems and the program "Ascold / DX-Complex Regina 2000" / InitRegina. exe.
Results and Discussion. Disorders of local hemodynamics and violations of the rheological properties of blood were observed in all patients with generalized periodontitis II, II-III degree.
The analysis of qualitative indicators indicated a deviation from the normal configuration of the rheogram with a steep anakrota, a sharp peak and a smooth, sloping descending part. The values of the quantitative parameters of the patients' rheogram before treatment also differed significantly from the normal parameters. The lowest efficiency of treatment was observed in patients of the 1st group. 6 months after surgery, the RI value increased by 1.6 times, and the EBFI increased by 1.2 times. The average value of VTI decreased by 4.35%, PRI by 10.14%, VOI – by 5.04%. 12 months after the operation, deterioration of quantitative and qualitative indicators was observed. There was a positive trend compared to the data before surgery, but the results of the treatment were significantly different from the norm.
In patients of the II group, after 6 months, a significant increase in RI and EBFI was observed by 2.1 and 1.5 times, respectively. Average values of VTI (by 7.43%), PRI (by 6.22%) and VOI (by 4.64%) decreased. After 12 months, a slight deterioration of rheographic indicators was observed compared to the results 6 months after the operation. In group III, after 3 and 6 months, similar dynamics were observed as in group II.
The most pronounced changes were observed in patients of IV group. 6 months after treatment, the average values of RI and EBFI increased by 2.3 and 1.6 times, respectively. VTI, PRI and VOI decreased by 8.74%, 11.39% and 7.44%. After 12 months, the quantitative indicators were not significantly different compared to the indicators after 6 months.

Published: December 2024

Dyscoloration of teeth hard tissues is a fairly common problem among the population of our country. Therefore, different methods of teeth whitening treatment are highly popular in the field of modern aesthetic dentistry. Due to a high demand of teeth whitening procedure, there is a great interest in researching the issue of color at dentistry.
The main goal. Comparative assessment of tooth color (in vitro) using digital image before and after procedure with a help of a hydrogen peroxide-based whitening system.
Materials and methods. The study was conducted on permanent teeth that were removed for orthodontic indications at patients aged from 18 to 39 years. Comparison of effectiveness color change after bleaching procedure was conducted on two halves of teeth divided in a half. The separation was carried out in the longitudinal direction along the axis of the tooth. Teeth whitening was performed according to the following steps: professional dental hygiene/Air Flow/application of the “Beyond” 35% H2O2 whitening gel/12 min, activation with blue light/3 times/remineralization therapy.
Results. Comparing digital images of teeth before and after whitening with the “Beyond” system and E according to the CIELAB color space between the colors of two tooth parts we indicate from 22 to 40 units,
E 34,0±5,9. The quality of whitening is mostly pronounced at patients with an average degree of staining, in which the tooth shade corresponds to shades from C2 to B3 according to the reorganized VITA scale.
Conclusions. The usage of color science at dentistry, combined with instrumental methods of measuring tooth color, allows us for qualitative and accurate determination of shade and whiteness. Our patients experience rapid and safe improvement of tooth color after whitening with the Beyond system, according to the CIE L*a*b* system, E between the colors of two tooth particles is from 22 to 40 units, on average 34.0±5.9 units.
COMPARISON OF DIGITAL AND CLASSICAL PROTOCOLS IN THE TREATMENT OF PATIENTS WITH COMPLETE MAXILLARY ADENTITY USING THE "ALL ON FOUR" TECHNIQUE: A 3-YEAR FOLLOW-UP
Authors: Proshchenko A.M. , Shynchukovskyi I.A.
Published: December 2024

Today there is a problem of significant prevalence of complete adentia. A modern solution to this problem is implantation followed by prosthetics. However, modern prosthetics is currently impossible without adequate implantation. One of the most predicted methods of implantation in patients with complete edentia is the "All on four" method, which includes the installation of 4 implants at specific angles in the alveolar process.
The purpose of this study was to compare digital and traditional protocols in the treatment of patients with complete maxillary adentia using the "All on four" technique during a 3-year follow-up period according to the following parameters: implant survival during a 3-year follow-up period; alveolar ridge height in the implant sites at the end of a 3-year follow-up period; assessment of patient satisfaction with the treatment at the end of a 3-year follow-up period (aesthetic and functional components).
Research methods. 70 patients with complete maxillary edentulousness who were treated using the "All on four" technique participated in the study. The total number of implants was 280 units. Implant survival during the 3-year follow-up period was determined at the end of the study by the number of retained implant units. The height of the alveolar ridge in the implant sites was determined at 36 months after the final prosthetics using CBCT data in Planmeca Romexis® software. The patient's satisfaction with the treatment was assessed at 36 months after the final prosthetics on a scale from 0 to 10 points, where 0 meant extreme dissatisfaction with the result, and 10 meant complete satisfaction.
The scientific novelty lies in the comparison of the traditional and digital protocols from both the clinician and patient perspectives. The study was also long, with follow-ups conducted over 3 years.
Conclusions. When using the digital protocol, a higher percentage of implant survival was observed at the end of the 3-year follow-up. Patients' assessment of the results of treatment using computer-assisted planning is higher than the assessment of the results of treatment by patients who underwent rehabilitation according to the traditional protocol.

Analysis of the wind waves dispersion relation becomes complicated if drift current is present. In general, this relation is derived from the Rayleigh equation, which does not have an analytical solution for an arbitrary velocity profile. In the limiting case, when the gravity-capillary wavelength is small compared to the typical flow depth, the simple Doppler approximation can be used. But in general, this approximation is not valid, and it necessary to take into account the vertical profile of horizontal velocity up to the depth, which corresponds to the considered wavelength. The velocity profile of the drift current is determined using Particle Image Velocimetry. High-resolution spatiotemporal spectra of the waves are obtained with color schlieren technique. Small addition of sodium dodecyl sulfate enabled us to estimate the influence of soluble impurities on the structure of the drift current and modification of the ratio between the drift current depth and the gravity-capillary wavelength. In the present work, an algorithm for numerical calculation of the dispersion relation for a given velocity profile is proposed. It is shown that the dispersion relation for a wind channel is adequately described by Rayleigh equation and the angle between the wave propagation direction and the wind, which is introduced in geophysics for correction of the dispersion relation, may be actually related to different values of the ratio between the wavelength and the drift current depth.

Current Earth climate changes are caused by the violation of the planet’s radiation balance (RB). In this study the changes of the one of RB’s components – yearly and monthly averaged global and regional outgoing thermal radiation of Earth or the Earth own radiation (EOR) in a spectral range 660–1300 cm-1 for 2015–2022 by IR Fourier-spectrometer IKFS-2 onboard the “Meteor-M” No2 satellite – is analyzed.
It is shown that EOR on a global scale in a range 660–1300 cm-1 on average decreased during the period of 2015–2022. Mean integral radiation in the same wave-lenght range decreased by ~0.5 W m-2 during 2015–2022. The most pronounced decrease of EOR was found in tropics, when the least pronounced – on polar latitudes. Besides, a negative trend of the integral EOR was found in tropics (up to 0.95–1.3 ± 0.1 W m-2 for the 8 years) with relatively high coefficient of determination (0.46–0.57). At the same time, there is no pronounced trend of EOR on the polar and middle latitudes.

Published: December 2024

The results of continuous observations of mass concentration of black carbon and aerosols PM10, PM2.5 in the near-surface layer of the atmosphere in the center of Moscow metropolis in 2022 are considered. The interpretation of the results was carried out applying the meteorological data, backward trajectories of air mass transport to Moscow and MERRA-2 reanalysis data on the spatial distribution of dust and black carbon in near-surface air of the center of the European part of Russia. The days (less than 9%) of an extreme increase in black carbon and PM10 concentrations due to atmospheric transport of fire aerosols or dust to Moscow from other regions are highlighted. The variability of a typical aerosol (outside of such episodes) in the megalopolis has been studied at different time scales – from daily to monthly and seasonal ones. The main contribution of dust and carbon-containing aerosols to megalopolis atmosphere is made by local anthropogenic sources (transport, thermal energy, industrial enterprises, construction facilities). A high correlation has been established between the concentrations of black carbon and PM2.5 particles in daily and seasonal changes. The data on air pollution with black carbon and aerosols PM2.5 and PM10 in large cities of the world show that the Moscow metropolis does not exceed the major cities of Europe and North America in terms of aerosol pollution.

Reconstructing the field of currents using remote sensing methods is a traditional task of oceanology. Satellite instruments such as altimeters, Doppler radars, and optical sensors are routinely used to solve oceanological problems for waters with large dimensions (open areas of the seas and oceans). The latter work well for reservoirs with significant water temperature gradients when applying the method of processing successive satellite images with varying time delays. Less commonly, areas of intense phytoplankton blooms, which are usual for productive waters, are used as markers for image matching. Such waters can be monitored with satellite ocean color sensors that provide high spatial resolution. The goal of the present paper was to investigate the possibility of reconstructing the flow field in the Gorki Reservoir, as an example of a medium-sized eutrophic reservoir, from sequent images of two different high-resolution ocean color sensors with a short time delay between images. This paper describes the field experiment under the satellite overpasses and presents the results of applying the maximum correlation method to two satellite images for retrieval of the current field in comparison with shipboard data. It is shown that the proposed method has prospects for development.
Interpretation of the transit light curve in the presence of one principal minimum taking into account the eccentricity of the transit (planet) orbit
Authors: Abubekerov M. K. , Gostev N. Yu.
Published: December 2024

Using a high-precision algorithm for interpreting transit light curves in a model of a classical eclipsing binary star-exoplanet system, we investigated the possibility of determining the system parameters in the absence of a priori knowledge of the orbital eccentricity. It was shown that it is impossible to determine the exact value of the eccentricity and periastron longitude based on the main minimum of the transit light curve alone. Also, with an observational accuracy of about 1% of the eclipse depth, the uncertainty in the eccentricity and periastron longitude together causes a significant uncertainty in the values of the component radii (an error of 2–3 times relative to the true values) and the orbital inclination angle. However, the ratios of the system component radii and the limb darkening coefficients are determined with good accuracy. With an increase in the observational accuracy to 0.1% of the eclipse depth, it becomes possible to determine the component radii and the orbital inclination angle when interpreting the light curve taking into account the eccentricity.

The results of the analysis of interplanetary scintillation observation data obtained by the radio telescope Big Scanning Antenna of the Lebedev Physical Institute (BSA LPI) before, during and after the magnetic storm that occurred on December 1–2, 2023, are presented. The observational data are compared with model calculations for corotating and propagating large-scale disturbances. The results of observations of scintillating radio sources indicate that the magnetic storm that took place was caused by a superposition of two types of large-scale solar wind disturbances. On the day before the start of the magnetic storm, signs of interaction between the Earth’s magnetosphere and the corotating region of multi-velocity solar wind flows were observed, whereas later signs of magnetosphere disturbance by coronal mass ejection spreading after the M9.8 solar flare on November 28, 2023, were observed.

Published: December 2024

Studies were carried out on the seasonal dynamics of phytoplankton in the Volga r each of the Kuibyshev r eservoir in 2017. At the same time, the seasonal values of the main abiotic environmental factors influencing the dynamics of phytoplankton (level regime, intensity of incident solar radiation, a number of basic hydrochemical and hydrophysical indicators, etc.) were analyzed. The dominant phytoplankton complex consists of blue-green, green volvox, centric diatoms and dinophytes. The studied area is subject to extremely intense processes of “blooming” of water due to the mass reproduction of blue-green algae species Microcystis, Aphanizomenon and Anabaena , and the waters of the studied area during most of the growing season corresponded to the mesosaprobic type and a moderately polluted zone.
Long-Term Changes in the Growth of Muksun Coregonus muksun in the Ob River
Authors: Matkovsky А. К. , Krasnoperova Т. А.
Published: December 2024

In the long-term aspect (from 2000 to 2020 years), there is a decrease in the growth rate of individuals of the muksun of the Ob River. These changes occur against the background of population decline, are unnatural and associated with long-term highly selective fishing and climate warming. As a result of climate warming, the feeding conditions of the muksun have worsened, as well as competition from other more thermophilic species has increased. Prolonged intensive and highly selective fishing is the main negative factor that has led to a change in the population size/age structure. In general, the changes are in the direction of stunting, and a further decrease in reproductive capacities of muksun specimens and productivity indicators of its population.
Influence of Migrations of Some Azov-Black Sea Basin Fish Species on Their Invasion with the Nematode Hysterothylacium aduncum in Different Seasons
Authors: Zavyalov A. V. , Sibirtsova E. N.
Published: December 2024

The paper examines the influence of pre-spawning and post-spawning planktophagous and ichthyophagous fish migrations on the invasion degree of nematode Hysterothylacium aduncum (Rudolphi., 1802) in the northern part of the Azov-Black Sea basin. For the first time, a decrease in the parameters of invasion with an adult nematode in herring during its wintering in the Black Sea has been shown, compared with similar indicators during the period of post-spawning migration after spawning in the Azov Sea. According to the authors, the diet change is the main cause of the difference in the invasion rate of migrating planktophagus as well as ichthyophagous fish. The authors consider that one of the indirect reasons for the differences in the invasion values of migrating fish is the inequality in salinity in disparate water areas of the northern parts of the Black and Azov Seas.

Significant individual variation of nitrogen and carbon isotope composition (δ 15 N and δ 13 C values) in white muscle tissues was found in samples of three cyprinid fish species, Cyprinion macrostomus (periphytonophage), Cyprinion kais (benthophage), and Luciobarbus schejch (omnivore), collected in a small tributary of the upper Tigris system (Turkey). In particular, exceptionally low value (1.7‰) and abnormally wide intraspecific variability (from 1.7 to 15.8‰) of δ 15 N were observed in C. macrostomus . Despite samples were collected synchronously and syntopically, very broad range of δ 15 N values points out possible heterogeneity of the samples. The studied watercourse is located in the zone of agriculture with intensive chemicalization and pollution of the river by mobile forms of nitrogen (mostly ammonium) could play a significant role in lowering δ 15 N values, especially in the periphytonophage. Along with that, fish with high (normal) δ 15 N values are supposedly recent migrants that came from a large river for joint spawning with resident fish. The pollution of water bodies as well as the presence of migrations should be taking into account in stable isotope analyses-based studies on trophic ecology of fishes.
