Published: July 2024

Upon condensation of 2 equiv. of 3R*,3aR*,8bS*-3-iodo-7-methyl-1,2,3,3а,4,8b-hexahydrocyclopenta[b]indole with 1 equiv. of glutaric or decanedicarboxylic acid dichloranhydride [N4,N4′-di-(3R*,3aR*,8bS*,3′R*,3a′R*,8b′S*)- and N4,N4′-di-(3aR*,3aR*,8bS*,3′S*,3a′S*,8b′R*)-3-iodo-7-methyl-1,2,3,3а,4,8b-hexahydrocyclopenta[b]indolyl]alkanediamides were synthesized. Their didehydrohalogenation to 3aR*,8bR*,3a′R*,8b′R*- and 3aS*,8bS*,3a′R*,8b′R*-1,3a,4,8b-tetrahydroanalogues was carried out by boiling these diiodides in piperidine. The presence of rotamerism in the products of dehydrohalogenation was shown, which is manifested by doubling the signals in the NMR spectra in different ratios. Nitration with trifluoroacetyl nitrate in CH2Cl2 yielded their 5,5′-dinitro analogs, which, when reacted with freshly prepared Fe(OH)2, along with 5,5′-diamino derivatives, also formed 5-amino-5′-nitro-substituted products of incomplete reduction. When a nitro group or an amino group appears at the C5 and C5′ carbon atoms of the cyclopenta[b]indole fragments, the doubling of the signals in the NMR spectra disappears. The interaction of a 5,5′-diamino derivative (n = 8) with decanedicarboxylic acid dichloride yielded a compound with 30 atoms in the macrocyclic ring.

distribution with the fault network defined from seismic data, and kinematic characteristics of seismic activity spatial migration are obtained. It is shown that seismic events recorded by the Norwegian NORSAR regional network within the Russian part of the Barents Sea shelf are grouped into linear clusters along shear kinematics faults. The fault network displaces Mesozoic seismic complexes and reaches the bottom surface, displacing quaternary deposits, which clearly indicates the modern age of displacements along which linear clusters of weak seismicity are grouped. The calculation of the total seismic moment in the space-time dimension showed the presence of seismic activity migration along short fragments of faults on the shelf with velocities from 10.5 to 25.7 km/year. There has been a surge in general activity in the shelf area since 2012. A comparison of the temporal evolution of seismic activity on the shelf with fragments of the Atlantic-Arctic Rift system suggests that it is the effect of tectonic deformation waves triggered along the geodynamically active intraplate boundary and propagating to the shelf at a speed of 20–22 km/year. Migration rates with speeds up to 77 km/year are less likely. There is a possibility that the increase in the intensity of seismic activity on the shelf after 2012 is not an emission from the effects of a slow deformation wave, but the result of a direct trigger effect on the shelf from the structures of the Knipovich and Gakkel ridges.

Enhancing Power Transformer Oil Quality Weight Factor using A Genetic Algorithm
Authors: Wijayaningrum Vivi Nur , Abdillah Muhammad Navis , Abdullah Moch Zawaruddin
Published: July 2024

Power transformers are critical to electrical power systems but are prone to failures due to factors such as heat, electricity, chemical reactions, mechanical stress, and adverse environmental conditions. Moni-toring the insulating oil effectively is key to preventing these failures. A major challenge in this process is determining the optimal weights for the oil quality index, which lacks a standardized benchmark and often relies on subjective expert assessments. To reduce expert bias and subjectivity, this research utilizes a genetic algorithm to optimize the weightings for five essential parameters: color, water content, break-down voltage (BDV), interfacial tension (IFT), and acidity. The algorithm operates through three stages: crossover, mutation, and selection, and analyzes data from 504 oil tests across various transformers. The mean absolute percentage error (MAPE) is used as the fitness value to assess the algorithm's effective-ness. The optimization process determined the best conditions as 132 iterations, a population size of 180, a crossover rate of 0.2, and a mutation rate of 0.8. These parameters achieved an average MAPE of 1.799% over ten trials, indicating high accuracy. This research not only optimizes the weighting of the oil quality index but also significantly reduces the need for expert input and subjective judgments in trans-former maintenance. The findings are expected to improve the efficiency and reliability of power trans-formers, thereby minimizing failures and associated economic costs.
Detection of Bias in Machine Learning Models for Predicting Deaths Caused by COVID-19
Authors: Zachra Fatimatus , Basuki Setio
Published: July 2024

The COVID-19 pandemic has significantly impacted global health, resulting in numerous fatalities and presenting substantial challenges to national healthcare systems due to a sharp increase in cases. Key to managing this crisis is the rapid and accurate identification of COVID-19 infections, a task that can be enhanced with Machine Learning (ML) techniques. However, ML applications can also generate biased and potentially unfair outcomes for certain demographic groups. This paper introduces a ML model designed for detecting both COVID-19 cases and biases associated with specific patient attributes. The model employs Decision Tree and XGBoost algorithms for case detection, while bias analysis is performed using the DALEX library, which focuses on protected attributes such as age, gender, race, and ethnicity. DALEX works by creating an "explainer" object that represents the model, enabling exploration of the model's functions without requiring in-depth knowledge of its workings. This approach helps pinpoint influential attributes and uncover potential biases within the model. Model performance is assessed through accuracy metrics, with the Decision Tree algorithm achieving the highest accuracy at 99% following Bayesian hyperparameter optimization. However, high accuracy does not ensure fairness, as biases related to protected attributes may still persist.

Authors: Gumilar Surya
Published: July 2024

This article critically examines the prevalent focus on conceptual understanding in Indonesian physics education research, particularly emphasizing abstract concepts like electricity and heat transfer at different educational levels. The author challenges the common perception that certain physics concepts, such as force, are inherently abstract, asserting that all physics concepts possess an abstract nature. The recurring choice of investigating electricity-related topics, driven by their perceived abstractness, is questioned. The author observes a consistent use of similar research instruments across primary, junior high, senior high, and university levels, raising concerns about the lack of adaptation to students’ varying capabilities of abstraction. The argument is presented for aligning research topics with age-appropriate conceptual understanding, challenging the uniformity in the development of research instruments across different educational levels. In a parallel context, the article underscores the importance of visual representation as an evaluation tool in physics education. The scarcity of research in Indonesia utilizing visual representation is noted, attributed to students’ confusion and a lack of understanding. Visual representation is posited as crucial for gauging students’ comprehension of scientific concepts, with examples given in the realms of collisions and climate changes. In conclusion, the author hopes this issue becomes a reference for future physics education research, urging researchers to delve into robust studies on conceptual understanding and visual representation. The article underscores the pivotal role these elements play in shaping the trajectory of physics education research, advocating for a more nuanced and tailored approach to investigations in these areas.

Authors: Ramdani Rida , Nurahman Arip
Published: July 2024

Understanding students’ preconceptions is an important initial step towards meaningful and appropriate physics learning. Particularly in the concept of collisions, students’ understanding of collision concepts often does not align with those established by scientists. Therefore, to explore students’ preconceptions, visual representation enables students to connect their experiences with specific concepts. This aids in revealing and diagnosing students’ preconceptions. This research aims to analyze high school students’ preconceptions regarding collision concepts by examining their visual representations. The research design employs a qualitative descriptive research design with data collection methods including observation sheets and interviews. Observation sheets containing visual representations by students are analyzed using a four-step semiotic analysis approach, while interview data is analyzed thematically. Seventy-two tenth-grade students were sampled offline using convenience sampling. The research findings reveal that students’ use of visual representations indicates diverse preconceptions about collision concepts, categorizing them at the macroscopic level. This data is examined across four categories of student visuals: (1) 11 visuals that are correct; (2) 18 visuals based on the objects used; (3) 34 visuals depicting different types of collisions; (4) and 29 visuals that are incorrect.

Published: July 2024

The learning that is widely recommended to improve science skills is project-based learning. Several studies show that the application of project-based learning models or methods or learning strategies increases motivation, achievement, problem-solving abilities, and so on. However, in reality, in the field, teachers have difficulty adopting project-based learning in schools, because several supporting factors are inadequate. Supporting factors for the success of project-based learning include a comprehensive curriculum, learning environment, appropriate assessment, student self-efficacy and support from stakeholders, especially parents. This critical review study reviews how research on project-based learning produces learning outcomes according to Project-based learning standards. In the initial stage, the author looked for as many articles as possible regarding project-based learning, especially in the science field, provided the articles were reputable. Then, reputable articles are selected that are appropriate to the implementation of project-based learning. The results of the critical review study show three important points in implementing Project-based learning to be more successful, namely: comprehensive curriculum support; the approach widely used in Project-based learning is STEM; and the implementation of Project-based learning must be adapted to suit the characteristics of students.

Implementing cooperative learning model with peer tutoring to enhance understanding of Wave concepts in high school
Authors: Kartikasari Hanifah
Published: July 2024

The difficulty of presenting teaching aids in the classroom makes it challenging for students to understand the material on sound waves, as sound waves are difficult to observe with the naked eye. Therefore, a learning model that facilitates student comprehension of sound waves is needed. This study aims to investigate the impact of a cooperative learning model using peer tutoring on students' understanding of sound wave concepts. The research method employed is quantitative, utilizing a quasi-experimental design with a nonequivalent control group. The study involved 76 students divided into experimental and control classes. The instrument used was a multiple-choice test consisting of 15 questions. The study was conducted over three sessions, starting with a pre-test in the first session and concluding with a post-test in the final session to determine the effect of the tested variable. The results indicate that the cooperative learning model with peer tutoring significantly affects students' conceptual understanding, with an average score of 64.04 in the experimental class compared to 53.86 in the control class. Additionally, the N-Gain test results show 41% improvement, categorized as moderate. Analysis of concept comprehension revealed an increase in understanding, with approximately 88.16% of students mastering the interpretation aspect of the concept.
Features of determining the estimated length of positive arches made of laminated wood
Authors: Mykhaylovskyi Denis , Skliarov Ihor , Skliarova Tetiana
Published: July 2024

The issue of loss of stability of arched structures is very important in engineering practice and design. This issue is especially key from the point of view of reliability and safety and economic losses, since structures of this type are usually used in buildings with a consequence class of at least CC2. [1].Laminated timber arches are long-span com-pression-bent elements in which the loss of stability plays a major role in determining the cross-sectional dimensions. In contrast to beams, an arch has a much larger ratio between the length of the element and its cross section, which in turn increases the risk of loss of stability. The loss of stability of an arch and its cor-rectly determined design length are directly related. The design length is defined as the value at which an arch can lose its stability under the influence of external loads. The main aspects of this relationship are: the value of the design length of the arch; mechanisms of loss of stabil-ity; dependence on the material and shape; ac-curacy of engineering calculations.It should be noted that recommendations for determining the design length of an arch are contained exclusively in the methodological lit-erature and outdated regulatory documents, such as [7]. In the latest current regulatory doc-ument [8], this issue is resolved by checking the strength and stability of the element, without limiting the flexibility. Since the flexibility of the element depends on its design length, the is-sue of determining this parameter remains open and relies directly on the design engineer, or rather, on his experience and competence. This issue is very relevant, given that a minor error in determining the design length significantly affects the results of testing compressed-bent elements.As a result of the work carried out, we analyzed the determination of the design lengths of hollow arches with different shapes and types of loading using two calculation methods: analytical formulas and the finite element method using the LIRA-SAPR-2019 software. Based on the calculations, recommendations for determining the design lengths of arches are given.

Published: July 2024

In today's conditions, the development of underground space can rightly be considered one of the most important and dynamic directions in civil and industrial construction at the worldlevel.
In Ukraine, underground construction is important in connection with Russia's aggressive war. Underground and buried structures are most actively built in large cities and megacities. The main reasons for the need to use underground space in cities include the lack of free territories within historically formed buildings and requirements for urban infrastructure development.
Today, the underground space is used not onlyfor the placement of engineering communicationsand transport facilities, but also for the construction of public complexes, multi-story underground garages and parking lots, shopping centers, as well asburied parts of residential and office buildings.
Structural solutions for underground and buried structures, as well as their construction methods, depend on spatial planning solutions, purpose, depth of laying, engineering-geological, climatic and seismic construction conditions, surface loads, and the proximity of other buildings and buildings.
Today, the maximum depth of pits designed inurban conditions usually do not exceed 25-30 m, and the number of underground floors is five to six.
Given the growing demand for underground space, especially in densely populated areas, designers and engineers face a number of challengesthat require innovative approaches and modern technologies. This includes the use of the latest methods of geotechnical modeling, the use of highquality materials that ensure the durability and safety of structures, and the implementation of effective water drainage and waterproofing systems.
Particular attention should be paid to safety issues during the construction and operation of underground structures, as they may be exposed to natural and man-made factors, such as groundwater, soil movement, and seismic activity. An important aspect is also the provision of comfortable conditions for people using underground facilities, which includes ventilation, lighting and evacuation routes.
Scientific research and the experience of international projects demonstrate that the correct use of underground space can significantly increase the efficiency of the use of urban areas, contribute to the steady development of cities and improve the quality of life of their residents. Investments in underground construction are becoming more and more justified in view of the long-term benefits and theneed to adapt to the conditions of the modern urban environment.
In general, underground construction is an important direction that has significant potential for development and improvement in the future, responding to the challenges of time and contributing to the development of modern infrastructure.

Alignment Error Estimation of the Conductive Pattern of 3D-Printed Circuit Boards
Authors: Smirnova O. N. , Aleksandrov A. A. , Bobrova Yu. S. , Moiseev K. M.
Published: July 2024

Introduction. When manufacturing printed circuit boards (PCBs), including their prototypes, the proper alignment of PCB layers is mandatory. While the causes and preventive measures against misalignment in PCBs manufactured using conventional technologies are known, research into alignment errors in 3D-printed PCBs is still ongoing. Another task regarding 3D printing, which is related to topological accuracy (alignment errors in particular), consists in ensuring the opportunity to remove the printed part of the product in order to perform operations thereon, such as embedding components, followed by its return and continuation of the printing process.

Aim. Numerical estimation and analysis of the causes of layer-to-layer alignment errors in PCBs manufactured using 3D printing.

Materials and methods. The research was conducted using the following materials and equipment: Polyethyleentereftalaatglycol (PETG); an Ultimaker Cura slicer; an Ender 3 S13D printer; a brass nozzle with a diameter of 0.3 mm. The study was conducted using the facilities of the Additive Technologies Center, Bauman Moscow State Technical University. Interlayer alignment errors are estimated by microsection analysis and X-ray inspection, as well as using the misalignment decomposition method described by Yu.B. Tsvetkov for electronics.

Results. The possibility of manufacturing PCB prototypes with three conductive layers is demonstrated, including a method for removing the printed part of the product and its further return in the printing process using printed pins. Large-scale distortions were found to make the largest contribution to the alignment error: on average, approximately 150 gm for each layer when compared to its 3D model and approximately 60 gm when comparing the topology of the top layer with the bottom layer. These values exceed the common misalignment value of 50 gm for the pin lamination process. This substantiates the need to control and minimize temperature effects, e.g., using 3D printers with a thermostatically-controlled chamber.

Conclusion. The conducted analysis of possible causes of misalignment emergence determines the significance of temperature gradients that occur during 3D printing. The proposed manufacturing method allows the printed part of the product to be removed and further returned into the printing process, which can be used to produce PCB prototypes with three conductive layers.
Spiritual education and imperial narratives: the ukrainian past in the mirror of diocesan magazines of the second half of the 19th century

Published: July 2024

The purpose of the article is to analyze the role of Orthodox spiritual journals of the second half of the 19th century in the spread of imperial narratives about the history of Ukraine. The research is aimed at determining the mutual influence of the publications of ecclesiastical diocesan publications with the state ideology, as well as analyzing the connection of these publications with the modern propaganda of the Kremlin and the Russian Orthodox Church against Ukraine. The methodological principles. Based on the analysis of historical literature and the source base, the article’s author used the methods of historical analysis and synthesis to examine the imperial narratives in the Orthodox spiritual journals of the period under study. The research also uses the comparative method and the method of systematic analysis to study the topics of publications of magazines of individual dioceses, as well as to determine the influence of the views of pre-revolutionary Orthodox publicists on the modern narratives of the Russian Orthodox Church regarding Ukraine. The scientific novelty of this topic is based on an attempt to analyze the variability of the thematic spectrum of historical publications issued in various diocesan journals and on revealing views on interfaith relations in the historical retrospective of Orthodox authors and determining the influence of these views on the beliefs of the hierarchs of the modern Russian Orthodox Church. Conclusions. The authors analyzed the topics of historical publications issued in the unofficial part of diocesan journals in the territory of the Russian Ukraine and the Cholm-Warsaw diocese. Interrelationships and regional differences of imperial narratives in Orthodox diocesan journals were traced. The role of diocesan information in relaying these narratives, as well as their reflection in modern Kremlin propaganda against Ukraine, is highlighted. It is asserted that the diocesan Orthodox publishing houses of the second half of the 19th century played an important role in forming the Russian imperial vision of the past of Ukrainian lands. The study revealed their role in the spread of numerous regional variants of imperial propaganda. The indirect influence of these narratives on Ukrainian national historiography is noted, and the need to distance themselves from them for a better study of the past and opposition to Russian propaganda is specified.
Settlement of former military personnel in rural communities of the right bank of Ukraine after the reform of 1861

In the second half of the XIX century. the Russian army, which by that time had already become a social institution, formed a separate social status of the military throughout the empire, in particular on the territory of Ukraine. Its representatives were endowed with certain rights and privileges compared to other categories of citizens of the country. After the reform of 1861, significant social transformations took place in the Russian Empire. Previously settled peasants acquired civil rights and now independently solved problems related to the life of their own communities, in which they all had equal rights. That’s why settlement in their communities of representatives of the military state, who enjoyed the privileges granted to them, needed state regulation, which became the subject of this study. The purpose of the article is to highlight, on the basis of available scientific works, as well as archival materials, the conditions under which servicemen of the lower ranks of the imperial army, who were demobilized or received a long indefinite leave, had the right to settle and live in rural communities that had come out of serfdom. The methodological basis of the research was the principles of historicism, objectivity and scientificity. The implementation of these principles is complemented by concrete search, cognitive, historical and analytical methods. Scientific novelty is determined, first of all, by the formulation of a problem that has not yet been comprehensively investigated. Conclusions. The representatives of the military state, which was finally formed in the Russian Empire during the first half of the 19th century and had a significant influence on the Ukrainian lands, were mainly of peasant origin. Therefore, at the end of a long term of service, or during indefinite leave, they tried to return to the way of life they were familiar with before the start of military service. However, such categories of servicemen still differed in their legal status from the peasantry, which after the reform of 1861 acquired civil rights. Most peasant communities on the Right Bank of Ukraine were still in the status of temporarily obliged and still performed certain duties in favour of the landlord. Retired servicemen and soldiers on indefinite leave had the right not to perform these and a number of other duties. This circumstance distinguished servicemen who settled in peasant communities from the general mass of their inhabitants.

The article’s purpose is to highlight the history of the Podillia branch of the Russian Bible Society (RBS), which extended its activities from Kamianets-Podilskyi not only to Podillia province but also to Bessarabia and Moldova. In the appendix to the article, two documents stating the involvement of the Podilia branch in the international affairs of the British and Foreign Bible Society (BFBS) are published. The methodological basis of the article is the principles of historicism, objectivity, complexity and systematicity, as well as the methods of archival heuristics and source studies. The scientific novelty consists in the primary study of the activity of the Podillia branch in the international context, not as a structural unit of the RBS, but as one of the branches of the BFBS. Conclusions. The Podillia branch was one of the most numerous societies and the most powerful in terms of the scope of its activities. It had its own specifics, directly related to the ethnic and religious composition of the population of Podillia. It distributed the majority of the Holy Scriptures in Polish, as well as in Slavic and Hebrew languages since native speakers of these languages were predominant in the region. The branch was in contact not only with the St. Petersburg and Moscow RBS committees, but also with the Polish Bible Society, branches functioning in Belarusian cities, and BFBS missionaries. Receiving reports of other foreign branches of the BFBS, the members of the Podillia branch felt like participants of the worldwide community of Bible fans (Bible Union). A significant role belonged to missionary Robert Pinkerton who supported the Podillia Branch Committee on behalf of BFBS. It was inspired by the successes of the BFBS and its branches in Great Britain, France, Denmark, Sweden, Prussia, Poland and Germany, India, China, Persia, Turkey, African countries and tribes, including Ethiopia, North America, as well as all provinces of the Russian Empire.

This study aims to analyze the effectiveness of sediment control structures, such as sabo and consolidation dams, and river normalization on sediment control in the Omu River after the earthquake in Sigi Regency on September 28, 2018. The analysis was conducted using the Universal Soil Loss Equation (USLE) method based on average rainfall data over 20 years. Erosion and sedimentation volumes before and after the earthquake were analyzed to understand the changes. The results showed that in 2020, the erosion volume reached 120,700.27 m³/year, and sedimentation was 17,030.81 m³/year, an increase from 2017, which recorded an erosion volume of 91,282.60 m³/year and sedimentation of 12,879.97 m³/year. Sediment transport simulation with daily discharge over 12 years indicated that in Scenario-1, sediment could be reduced by 10.81%, and in Scenario-3 by 23.18%. Meanwhile, simulation with Q100 flood discharge in Scenario-2 showed sediment reduction by 47.18%, and in Scenario-4 by 62.96%. The general conclusion of this study is that sediment control structures and river normalization are effective in reducing sediment volumes. Specifically, the construction of sediment control structures has proven to significantly reduce erosion and sedimentation. This research highlights the importance of structural improvements in mitigating post-disaster erosion impacts. The results of this study can serve as a reference for planning and implementing sediment control in disaster-prone areas. Keywords: sediment control, sabo dam, consolidation dam, river normalization, Omu river

Fournier gangreni (FG), perineal, perianal ve ürogenital deri ve deri altı dokuların gangrenöz süpüratif bir hastalığıdır. Bu çalışmada kliniğimizde FG nedeniyle opere ettiğimiz hastalarımızda, Uludağ Fournier Gangreni Şiddet İndeksi (UFGSI)’ni kullanarak morbidite ve mortalitenin öngörülebilirliğini değerlendirmeyi amaçladık. Çalışmaya Ocak 2012 ile Aralık 2022 tarihleri arasında kliniğimizde FG nedeniyle ameliyat edilen ve çalışma kriterlerini karşılayan 35 hasta dahil edildi. Veriler retrospektif olarak hasta dosyaları incelenerek toplandı. 35 hastanın 10 tanesinde UFGSI skoru 9 ve üzerinde idi ve bu hastaların üçünde hastalık mortal seyretti. Skoru 9’un altında olan 25 hastadan sadece birinde mortalite görüldü. Tüm agresif tedavi seçeneklerine rağmen FG’nin mortalite oranı yüksektir. UFGSI skorlama sistemi mortalitenin güvenilir bir öngörücüsü gibi görülmektedir.
Building a Theoretical Framework from Weber’s Theory for Legal Scientific Research

Scientific work in the field of legal science in Indonesia often differs from the criteria for empirical scientific research at the level of modern science. The results of thesis and dissertation-level scientific research at law faculties have so far emphasized technical-juridical analysis for the needs of legal practice rather than academic research that criticizes and creates new scientific theories in the field of law. Dogmatic legal analysis, it seems, takes precedence over academic legal analysis that allows researchers to fulfill the critical scientific need for the renewal of legal dogmatics by the development of Society. The framework section is usually narrated without construction in the form of a 'theoretical framework' or 'analytical model' which often shows confusion in legal research. Legal dogmatic research focuses on evaluating the structure (language) of law and legal practice, i.e. how far the elements of the article as evaluation indicators are used with the resolution of the particular legal event being studied. Scholarly legal research often uses theory in presenting the framework for its theses and dissertations, and more than one theory is even related to the various narratives and descriptions of the proposed research. In addition, legal researchers present major frameworks in 'grand theory', 'middle-range theory', and applied theory' for research typically conducted in the field of pure science (pure social and human sciences).
