Authors: Zahra Fathia , Oktavia Rani , Azhar Aulia , Arif Khairil , Sari Monica Prima 
Published: November 2024

This research is based on the preliminary study conducted at SMPN 16 Padang which found that students' learning outcomes in science teaching are still considered suboptimal. This is indicated by several students' scores that have not yet met the Learning Outcome Completion Criteria of 80. This research aims to determine the effect of Problem-Based Learning (PBL) model assisted by PhET simulations on the learning outcomes of eighth-grade students at SMPN 16 Padang. The type of research is a quasi-experiment with a non-equivalent control group design. The population in this study is all the eighth-grade students of SMPN 16 Padang. Sample collection was conducted using purposive sampling techniques. Thus, the research samples were obtained from students in class VIII 2 and VIII 4. The research samples consisted of experimental class applying the Problem-Based Learning model assisted by PhET simulations and control class using the conventional learning model. Data collection was conducted through tests administered before (pretest) and after the treatment (posttest) on the experimental and control classes in the form of multiple-choice questions. The obtained data were analyzed using inferential statistical analysis, and the results of the two-sample t-test for the pre-test and N-gain were 0.002 for the pre-test significance and 0.000 for the N-Gain significance, which means was rejected or there was a significant difference between the two groups because the significance value (p) was less than 0.05. Thus, it can be concluded that there is a significant influence of the application of the PBL learning model assisted by PhET simulations on the learning outcomes of eighth-grade students in the subject of light and optical instruments.

Published: November 2024

Abstract
Currently used machine diagnostic systems are based on very modern solutions based on the acquisition and recording of their operating parameters in real time. Increasingly available and high-tech sensor systems mean that the number of recorded parameters is increasing and their quality is improving. These data are mainly used to assess the technical condition of machines and the processes they perform. In mining, these data can also be used to assess and, at a later stage, improve the safety of the underground mining process. Referring to this issue, the paper presents examples of the use of diagnostic systems for powered roof supports and longwall shearers to assess the safety status of the underground hard coal mining process. In the case of the wall support, the focus was on measuring the pressures in the stands of its individual sections. Temporary changes in the values of these pressures constitute a valuable source of information regarding the interaction of the support with the rock mass. In particular, this concerns the identification of the effects of the informational impact of the rock mass on the longwall excavation protected by the support. The research results presented in the paper, especially in the case of very dangerous dynamic impacts, indicate the possibility of both diagnosing the operating condition of the section and identifying symptoms of exposure to such events. This undoubtedly significantly expands the possibilities of using the measured pressures. Diagnostic signals from a longwall shearer are also widely used. The current intensities drawn by its motors while cutting the rock mass, as well as the advance speed and its position in the wall make it possible to analyze these parameters and their changes before, during and after the occurrence of various types of events. These data enable the assessment of the effects of the rock mass on its operational efficiency and safety status. It also enables the identification of symptoms that precede the occurrence of such events. The presented examples indicate the need for a broader and more holistic approach to the use of diagnostic parameters of mining machines. In particular, this concerns the study of the cooperation between the support and the rock mass and its influence on the efficiency and safety of the rock mass mining process. The subject matter addressed relates to very important and current issues, and the developed methodology and obtained results should be applied in practice as soon as possible.

Abstract
In the current decade, electricity consumption will increase by more than 16%. The main resources for electricity generation are oil – 2.53%; gas – 22.9%; coal – 35.98%; nuclear industry – 9.84%; hydraulic power regeneration – 15.01%; renewable sources – 12.85%; other – 0.89%. This causes global warming of the planet due to greenhouse gases increased emissions into the atmosphere. A resource capable to cover the thermal energy field’s balance is the nuclear energy. To compare the resources’ polluting capacity, it is necessary to introduce a general indicator that takes into account their properties. This study proposes an integrated approach based on the formation of groups of indicators reflecting greenhouse gas emissions; power consumption; economic activity, air quality, etc. For comparison needs, all indicators are normalized in dimensionless form and compiled with reference to their specific weight. Calculations of the pollution index for fossil resources and nuclear energy, carried out using this algorithm proved that the nuclear power, with a careful consideration of all possible polluting radionuclides (11 components), exceeds this indicator for gas by 22%, but is lower than ciphers for coal and oil by 36 and 26%, respectively. For two latters only 3 specific components being taken into account. Therefore, it seems advisable to use the considered complex indicator of environmental pollution to assess the resource safety level for electricity generation.
Sacred sources as objects of cultural heritage: on the issue of classification
Authors: Gibel'gaus Tat'yana Andreevna 
Published: November 2024

The subject of the study is sacred water sources, which can be recognized as objects of cultural and natural heritage. Sacred water sources are important objects of religious worship and places of pilgrimage, of particular importance to various cultures and religions. They are often accompanied by legends, which makes them unique and valuable objects of cultural and natural heritage. However, despite their importance, many sacred sources remain unidentified and unprotected, which can lead to their loss and disappearance. The authors, based on the results of expeditionary research conducted by scientists and graduate students of the Altai State Pedagogical University, hypothesized that sacred water sources can be identified as objects of cultural and natural heritage. In order to identify sacred water sources as objects of cultural and natural heritage, their study and typologization is necessary. The article analyzes various approaches to the typologization and classification of sources, including territorial, infrastructural, historical, ethnographic and anthropological. Particular attention is paid to the various levels of clericalization and infrastructural security of sources. The author examines various factors influencing the classification, such as the layering of meaning, local traditions and the variability of the status of sacred sites. The study also highlights the need for an interdisciplinary approach to typologization in order to take into account all aspects of their essence. Among other things, the authors focus on the term "sacred water source", which is insufficiently defined in the legislative framework and modern dictionaries. In general, the study highlights the need for a deeper and more systematic approach to the study and protection of sacred sites, which is important for preserving the cultural identity and spiritual heritage of the peoples of the country.

Published: November 2024

BACKGROUND: The knee joint anatomical structure is susceptible to external forces, which can lead to functional break down, profoundly affecting the quality of life and daily functioning of individuals. OBJECTIVE: To investigate the effects of continuous nursing intervention on walking function, quality of life, and treatment satisfaction in patients undergoing unicondylar knee replacement. METHODS: This prospective study included 90 patients who underwent unicondylar knee arthroplasty due to unicondylar osteoarthritis. Participants were divided into two groups based on their nursing methods: the control group (n= 45) and the observation group (n= 45). RESULTS: Three months post-intervention, the observation group demonstrated significant improvements in knee joint range of motion, Hospital for Special Surgery Knee Score score, and Lysholm knee joint score compared to the control group (P< 0.05). The observation group also had a shorter completion time for the Timed Up and Go test and significantly higher SF-36 scores (P< 0.05 for both). Additionally, Knee Injury and Osteoarthritis Outcome Score scores in the observation group were significantly higher after three months of intervention (P< 0.05). And the observation group reported higher satisfaction rates and lower dissatisfaction rates compared to the control group (P< 0.05). CONCLUSION: Early postoperative rehabilitation guidance, regular reviews, and rehabilitation exercise guidance result in better rehabilitation outcomes, enhanced knee joint function, improved walking ability, and overall quality of life for patients undergoing unicondylar knee replacement.

Published: November 2024

In this work we obtained some results on the real and complex roots of real polynomials of the form \({P{(x)}} = {x^{n} + {a_{n - 1}x^{n - 1}} + \cdots + {a_{1}x} + a_{0}}\), where the \(a_{k}\) are real numbers for \(k \in {\{ 0,\ldots,{n - 1}\}}\), we also obtained results on linear Diophantine equations of the form \({{ax} + {by} + {cz}} = d\), where \(a,b,c\) and \(d\) are integers.

To obtain the desired results, the relation that states the following was used: for any real numbers \(A\) and \(B\), there exists a unique real number \(\lambda\), such that \({A + B} = {\lambda{\lbrack{A^{2} + B^{2}}\rbrack}}\). This result is appropriately linked to the object of study.

For the polynomials, optimal domains were obtained where the real or complex roots are found, without the use of higher calculus.

For the linear Diophantine equation, the desired solutions were obtained, which were found by establishing several links between the Diophantine equation and the relationship \({A + B} = {\lambda{\lbrack{A^{2} + B^{2}}\rbrack}}\). Several examples of the results obtained are illustrated, which are intended to show the benefits of this proposal.

Additionally, we obtained the solution of Fermat’s last Theorem in an elegant, simple and unprecedented way, different from what has been done by other authors.

Analysis of Sustainable Efficiency of Freight Transport in Major European Economies: An Integrated Multi-Region Input-Output and DEA Approach
Authors: Abbood Kadhim , Mészáros Ferenc , Alatawneh Anas 
Published: November 2024

This paper integrates the multi-region input-output model (MRIO) and data envelopment analysis (DEA) methods to analyze the freight transport efficiency in Europe. Social, economic, and environmental influences were combined into a sustainable efficiency rating of the freight transport sector of Germany, France, Italy, Spain, and the Netherlands. First, the freight transport sector's carbon footprint (CFP) was quantified using the MRIO model. The lifecycle-based CFP emissions of freight transport activities were assessed using a dataset from 2000 to 2018. Nineteen stochastic model-based MRIO lifecycle assessments were built for each country. Secondly, sixty instances of DEA models were created using a linear program for each mode in the selected countries. Thirdly, the sustainable efficiency scores were determined for each freight transport mode in each country over four periods: 2000–2004, 2005–2009, 2010–2014, and 2015–2018. The results illustrate that the sustainable efficiency score of inland, water, and air transport modes ranged from 0.38 to 1.
The mammalian Ire1 inhibitor, 4µ8C, exhibits broad anti-Aspergillus activity in vitro and in a treatment model of fungal keratitis

Published: November 2024

ObjectiveThe fungal unfolded protein response consists of a two-component relay in which the ER-bound sensor, IreA, splices and activates the mRNA of the transcription factor, HacA. Previously, we demonstrated that hacA is essential for Aspergillus fumigatus virulence in a murine model of fungal keratitis (FK), suggesting the pathway could serve as a therapeutic target. Here we investigate the antifungal properties of known inhibitors of the mammalian Ire1 protein both in vitro and in a treatment model of FK.MethodsThe antifungal activity of Ire1 inhibitors was tested against conidia of several A. fumigatus isolates by a broth microdilution assay and against fungal biofilm by XTT reduction. The influence of 4μ8C on hacA mRNA splicing in A. fumigatus was assessed through gel electrophoresis and qRT-PCR of UPR regulatory genes. The toxicity and antifungal profile of 4μ8C in the cornea was assessed by applying drops to uninfected or A. fumigatus-infected corneas 3 times daily starting 4 hours post-inoculation. Corneas were evaluated daily through slit-lamp imaging and optical coherence tomography, or at endpoint through histology or fungal burden quantification via colony forming units.ResultsAmong six Ire1 inhibitors screened, the endonuclease inhibitor 4μ8C displayed the strongest antifungal profile with an apparent fungicidal action. The compound both blocked conidial germination and hyphal metabolism of A. fumigatus Af293 in the same concentration range that blocked hacA splicing and UPR gene induction (60-120 µM). Topical treatment of sham-inoculated corneas with 0.5 and 2.5 mM 4μ8C did not impact corneal clarity, but did transiently inhibit epithelialization of corneal ulcers. Relative to vehicle-treated Af293-infected corneas, treatment with 0.5 and 2.5 mM drug resulted in a 50% and &gt;90% reduction in fungal load, respectively, the latter of which corresponded to an absence of clinical signs of infection or corneal pathology.ConclusionThe in vitro data suggest that 4μ8C displays antifungal activity against A. fumigatus through the specific inhibition of IreA. Topical application of the compound to the murine cornea can furthermore block the establishment of infection, suggesting this class of drugs can be developed as novel antifungals that improve visual outcomes in FK patients.
