Authors: Gorbunov Aleksandr A. ,   Orenburg State University, Pripadchev Aleksey D. , Magdin Aleksandr G. ,   Orenburg State University,   Orenburg State University
Published: July 2024

The problem of training professional engineers in the field of aerospace engineering is considered. The current situation in training specialists for the design and development of highly complex, intellectually intensive aerospace technology requires a radical change in the strategy and tactics of training, since the main characteristics of a graduate are his competence and mobility. This is an extremely difficult task, the responsibility for solving which lies with the modern teaching elite. In this regard, the emphasis in the study of academic disciplines is transferred to the process of cognition itself, the effectiveness of which completely depends on the cognitive interest of the student himself. The success of achieving this goal depends not only on what is learned, but also on how it is learned: individually or collectively, in authoritarian or humanistic conditions, based on attention, perception, memory or on the entire personal potential of a person, using active methods training. As an example, the process of forming the aerodynamic appearance of a mainline aircraft at the preliminary design stage is considered.

Perceptions of teachers on the change in schooling : an empirical case study of Rwanda
Authors: Gahutu Charles
Published: July 2024

This study investigates the perceptions of teachers of change in schooling. It is contextualized in the After-Genocide Rwanda; a period marked by a plethora of social and economic transformations as well as sporadic educational changes. Similarly, the world is experiencing manifold changes which reshape social relations, individual and societal needs, the structure of the labour market and the understanding of life. The school system has been overhauled in its dimensions; however, this dynamicity did not get a similar echo from the scientific community. The study at hand stands out by its intention to give voice to teachers and bring to the fore their digestion of both changes in schooling and the current changing environment. A sample of 30 teachers was given room to share their perceptions of change through semi-structured interviews. The main finding of this research is the differentiated perception of the change by the teachers in three ideal types with associated different potentials to promote change: the instrumental understanding of the change as policy-oriented for a stable society, the vacillating understanding of the change as context adaptation-oriented for integration into the global world and the functional understanding of the change as human capital investment-oriented for a knowledge society. Again, this study reveals a differing perception of the changing world between optimism and pessimism. These findings have been discussed in line with theories of teachers’ agency in change, school improvement, and globalization.

AUTOMATED DRIVING SYSTEMS: COMPARISON OF TRAINING METHODS’ EFFECTIVENESS
Authors: RODAK Aleksandra , PEŁKA Małgorzata , KRUSZEWSKI Mikołaj
Published: July 2024

The second decade of the 21st century saw the introduction of vehicles equipped with various driver assistance systems. However, the producers' plans go much further. In January 2023, Mercedes-Benz's DRIVE PILOT system was approved for use on public roads in Nevada (United States) as the first and so far only SAE Level 3 series-production solution. Despite increasing automation, the human factor remains important for the safety and efficiency of road transport. In the coming years, and possibly decades, this will mainly be due to the co-existence of vehicles with varying degrees of automation and necessary driver-vehicle interactions in cases where an automated driving system crosses the boundaries of the operational design domain. The latest research reveals the limitations of driving assistance systems, pointing not only to the need for changes in the technological domain but also to the need to pay more attention to the psychological aspects of using assistance systems in cognitive and behavioral areas. Therefore, an additional element of automation implementation should be considered, which is driver training focused on modern technological solutions. Properly arranged and conducted training can be treated as an additional factor facilitating the implementation of automated mobility. The article describes the methods of assessing the effectiveness of training in terms of familiarizing drivers with the functions that automate driving. The authors present the results of tests carried out on a driving simulator with an implemented Level 4 system (according to SAE classification). Three forms of knowledge transfer were analyzed: practical training, e-learning, and training with a short user manual. The results were compared in terms of driver-vehicle interaction effectiveness (e.g., system activation), ensuring that the driver is sufficiently reactive in dangerous situations and understands the limitations of the system. The research was conducted on a group of 81 drivers aged 18–65. Driver training was one of the main pillars of the Trustonomy project, which received funding from the EU research and innovation program Horizon 2020 under grant agreement No. 815003.

Published: July 2024

This study seeks to explore the effectiveness of employing foldable containers (FLDs) in liner shipping to reduce relocation and the empty containers and bunker costs (BCs) associated with ship operations. This resolves a minimum-cost multi-commodity network flow problem by optimizing container fleet size and empty container relocation in a multi-port shipping service network. Port handling time and sailing speed provided by obtained optimal solutions enable the determination of ship BCs as a secondary step. The numerical experiments demonstrate the comparative effect of FLDs against standard ones on the reduction of the costs of empty containers and containership bunker oil.
ENHANCING ROAD SAFETY FOR VULNERABLE ROAD USERS – THE ROLE OF AUTONOMOUS EMERGENCY BRAKING SYSTEMS
Authors: PEŁKA Małgorzata , UCIŃSKA Monika , KRUSZEWSKI Mikołaj
Published: July 2024

Vulnerable road users are the largest group of road accident victims in the world. At the same time, it should be noted that most road accidents are caused by the motor vehicle driver. An opportunity to increase the level of road safety is emergency braking systems installed in vehicles. Their task is to detect the risk of a collision with another object, issue a warning to the driver and, in the absence of reaction, perform emergency braking. The publication presents the results of research conducted by the Motor Transport Institute as part of the PEDICRASH project. As part of the work, a series of tests of the autonomous emergency braking system were carried out to check unusual but probable cases of events in which it should work. The tests were carried out in a closed area using a few selected models of popular passenger car brands. An additional data acquisition system and dummies imitating vulnerable road users: pedestrians and cyclists were used. The constructions represent the silhouette of an adult person and meet the requirements of the Euro NCAP AEB Protocol. The time of the collision at the time of issuing a warning to the driver was analyzed. Assuming that the vehicle was moving uniformly, the distance from the obstacle was calculated at the time of issuing the warning and after the driver's reaction time (0.7 s and 1 s were assumed) from this signal. The deceleration necessary to brake the vehicle was calculated and it was determined whether the driver would have a chance to brake the vehicle before a pedestrian or a cyclist in a given situation. For cases in which the driver would not be able to brake in time, the speed of the vehicle with which it would hit the vulnerable road users was calculated. Possible injuries and accident costs were then estimated.

Authors: TUMMINELLO Maria Luisa , MACIOSZEK Elżbieta , GRANÀ Anna , GIUFFRE Tullio
Published: July 2024

This paper presents a simulation-driven method for assessing the safety and efficiency of traffic at roundabouts incorporating connected and automated vehicle (CAV) technology. Utilizing the newly proposed CAV-based factors specified by the Highway Capacity Manual (HCM) provided a practical framework for analyzing capacity dynamics across various traffic scenarios. Using microscopic traffic simulation on a roundabout model replicating real-world geometry and traffic attributes facilitated the identification of crucial behavioral parameters. This simulation spanned from smooth traffic scenarios to operational saturation, aiding in the study of mixed traffic scenarios during the transition to increasing CAV presence. Additionally, the study assessed the safety and traffic impact of a dedicated CAV lane using surrogate safety metrics. Aimsun software aided in model parameter calibration, which, combined with the Surrogate Safety Assessment Model (SSAM), supported safety analysis. Despite observed enhancements in roundabout performance with CAV integration, the benefits of a designated CAV lane highlighted the potential to reduce conflicts among vehicles. In conclusion, the paper emphasizes the overall performance enhancement achieved with CAVs at roundabouts while also providing insights for evaluating the potential of CAV technologies in future mobility management strategies.

Published: July 2024

The article deals with the problem of increasing the productivity of trucks in the performance of international road freight transportation in Eastern Europe and the European Union. There are restrictions on cabotage transportation (domestic cabotage), as well as time limits for the execution of orders and penalties for the execution of the entire volume of transportation in this case in addition to the restrictions of the European Agreement E/ECE/TRANS/564. The task of optimizing the required number of vehicles, drivers/driving crews, and route configuration was formulated and solved by mathematical programming with time constraints. At the same time, a variable method of organizing the work of drivers on adjacent routes was applied, by which drivers/crews are not assigned to a specific vehicle but are changed after a certain number of work hours. This minimized the non-productive idling of trucks, ensured compliance with the work and rest regulations of drivers, and minimized truck mileage on routes. In contrast to known methods and research results, the problem is solved with a guaranteed achievement of the optimum in an acceptable search time. This result was achieved due to the appropriate formulation of the solution conditions. The results can be applied in the logistic planning of transport processes.

China's nuclear power in the context of decarbonization of the global energy industry
Authors: Nazyuta Lyudmyla , Stepanenko Danylo
Published: July 2024

The global structure of energy resource consumption is analyzed. It is shown that the total consumption of energy resources in the 20th century increased almost 15 times and amounted to about 118 PWh in 2000. Of these, more than 80% were fossil (natural) energy carriers, 13 % were renewable energy sources and more than 6 % were nuclear power. This trend has continued for many years. Renewable energy sources and nuclear power are projected to dominate the growth of global energy consumption, meeting on average more than 90 % of the additional demand. China ranks first in the world in terms of GDP and the rate of development of the electric power complex, as well as in terms of production volume and the rate of development of nuclear power.  The structure of electricity generation by fuel type in countries (TOP 5, 2021) with high energy consumption has been analyzed. It is shown that the main players in this market are three countries: China (30 %), USA (13 %) and India (6 %). The volume of electricity production in China is almost three times larger than in the EU countries and almost 7 times larger than in Russia. The structure of nuclear energy and China's achievements in this field are considered. It is shown that in the context of nuclear technologies (creation of fourth-generation reactors, development of technologies close to the full closed cycle of nuclear waste processing) China is already ready to significantly expand the scope of nuclear energy. Special attention is paid to the safety of nuclear facilities operations. The main problem China will face is the absence of an insurmountable barrier between civilian and military use of such technologies. This poses a serious threat to the ecology and life safety of the country. In the long term, nuclear power must also solve the problem of safe, long-term disposal of radioactive waste. It is shown that in the future China needs to re-examine its nuclear program in the context of cooperation with International Nuclear Security Organizations.

Calculation of electrical energy losses in distribution networks for power supply using oil and vacuum circuit breakers
Authors: Semenov Anatolii , Kharak Ruslan , Arendarenko Volodymyr , Bychkov Yaroslav
Published: July 2024

A method for approximate estimation of load losses in distribution networks from 6 to 10 kV, as well as for lower voltage networks, has been proposed. The main advantage of this method is that the root mean square current is calculated only once for a series of calculations. This approach significantly reduces the time required for calculations and improves their accuracy, as it eliminates the need for multiple determinations of the root mean square current for each individual calculation. The proposed approach contributes to a better understanding of the influence of various factors on load losses, which allows for more effective planning and management of distribution networks. This is particularly important in the context of increasing loads on electrical networks and higher demands for their reliability and efficiency. In the calculation of electrical energy losses in distribution networks from 6 to 10 kV, methods that use generalized coefficients of electrical circuits and operating modes in the form of regression equations are widely applied. The most significant and independent factors, such as the input of active energy, total line length, number of line sections, total number of transformers, and their total installed capacity, must be taken into account and are included in the calculation equation. Additionally, the components used and their regular maintenance play an important role in electrical energy losses in electrical networks. The main direction of research is the optimization of distribution network parameters, taking into account the latest technologies and materials, as well as the implementation of automated monitoring and control systems that will allow timely detection and elimination of problems associated with electrical energy losses. The proposed method for estimating load losses in distribution networks is a promising direction for the development of the energy sector, which will contribute to improving the efficiency and reliability of electrical networks, as well as reducing the costs of their operation and maintenance.

Published: July 2024

The stunting rate decreased by 2.8%, which was 21.6% in 2022 compared to 24.4% in 2021. The decline is a positive development, but it is still above the threshold set by the World Health Organization (WHO) which should not exceed 20%. This shows that the problem of stunting in Indonesia still requires serious attention. The purpose of the study was to understand social intervention as one of the communication strategies in reducing stunting rates in Sidoarjo Regency. Interventions in communication for social and behavioral change include various methods such as interpersonal communication, the utilization of mass media, and community mobilization and its social aspects. Qualitative research approach with constructivism paradigm. The data collection method was an in-depth interview with 4 resource persons, namely a public relations officer of the Sidoarjo Regency Health Office and three mothers who were the target audience for reducing stunting rates. The results showed that efforts to reduce stunting were carried out through two social interventions, namely specific nutrition interventions to address direct causes and nutrition-sensitive interventions to address indirect causes. Social interventions are carried out in a convergent manner with an emphasis on handling the causes of nutritional problems. Social and behavioral change communication approaches are used to raise awareness about stunting so as to encourage pregnant women and stunted children to improve nutrition and behave healthily.
Jakarta Evolution Sustainability Innovation With the Presence of the Online Single Submission Risk-Based Approach System, a Solution for Licensing Services in DKI Jakarta Province
Authors: Danang Windiatmoko Agus , Taufik H.  , Asropi
Published: July 2024

The Indonesian government introduced the Electronically Integrated Business Licensing System, Online Single Submission (OSS), to enhance nationwide business operations. However, the DKI Jakarta Provincial Government concurrently implemented its electronic licensing system, the Jakarta Evolution System, leading to overlapping jurisdiction in license processing. The enactment of the Job Creation Law in 2020 marked a significant shift in licensing regulations, introducing a risk-based business licensing approach determined by the central government. Consequently, the OSS transitioned to the Base Risk Approach (OSS-RBA), mandated for adoption by all Regional Governments. This study addresses two key questions: 1) Examining the mechanism for organizing public services in the business licensing sector based on Online Single Submission in DKI Jakarta, and 2) Identifying obstacles in public services related to Online Single Submission in DKI Jakarta and exploring efforts to overcome these challenges. Employing a qualitative and descriptive research approach, the study highlights that the implementation of Online Single Submission in DKI Jakarta aligns with central government guidelines, consolidating almost all business licenses under OSS authority. Key obstacles include a lack of information and socialization, compounded by legal uncertainties from the central government. Mitigation efforts involve the introduction of innovative OSS-RBA support services, intensified socialization initiatives, and policy adjustments. The study underscores the importance of the DKI Jakarta Provincial Government conducting extensive socialization campaigns for OSS-based business licensing to solidify the legal foundation for risk-based licensing.

Authors: Wahid Wahyu Saputro  , Golwa Gian Villany
Published: July 2024

Electrical energy is widely used for household and industrial purposes, so the need for electrical energy will continue to increase every year. Therefore, it is necessary to develop an electrical energy generation system that comes from renewable energy such as wind. Currently, not much is known about the use of wasted wind from air conditioner (AC) condensers. The blow of wind can be used to produce electrical energy, so it is necessary to make wind-powered electric generator blades from the condenser output. The blade that will be designed is a three-blade model, so it is hoped that it can rotate the generator optimally. The purpose of this research is to design a three-blade type that can optimize the rotation of the electric motor/generator and get the maximum number of revolutions with a three-blade design because this design provides better stability and more efficiency. One way of making the design is to make simulation variations with computational fluid dynamics (CFD) in order to find out the right blade design to rotate the generator and find out the wind blowing from the air conditioner (AC) condenser that crosses the blade. In this study, three simulations were carried out to get maximum results, namely 390 rpm at 42 °C with a velocity of 10.7 m/s and a pressure of 34.4 Pa. To be able to determine the effectiveness of the AC condenser wind output speed with a three-blade design.

This research aims to look at the hardness and corrosion of the weld layer. In addition, distortions were also observed in the post-welding specimens. Weld layers were made with variations of one, two and three layers of welding using HV-800 electrodes. The first step in this research is a literature study, followed by preparing tools and materials, heating electrodes, welding process, observing distortion, cutting specimens for testing followed by hardness and corrosion testing, and data analysis and conclusions. From the results of observing the distortion, it can be seen that the thicker the weld layer, the greater the distortion that will occur. Distortions in specimens welded with one, two and three layers are 1.5, 4 and 6° respectively. Furthermore, based on the results of the hardness test, it can be seen that the thicker the weld layer, the greater the hardness. The hardness of the one, two and three layer welded specimens was 550.2, 632.82 and 650.68 HV respectively. Then, based on the weighing results, it can be seen that the longer the immersion time, the greater the reduction in mass during 120 hours of immersing. Finally, from the results of the corrosion rate calculation it can be seen that the thicker the weld layer, the lower the corrosion rate that will occur. The corrosion rates for specimens welded with one, two and three layers were 13.23, 11.02 and 10.29 mpy, respectively. All three specimens have good corrosion resistance because they fall into the "good" criteria.

Eğitim alanında yapılan reformların taşradaki yansımalarından bir tanesi de günümüz ortaokul seviyesinde eğitim-öğretim faaliyetinde bulunan rüşdiye mekteplerinin kurulmasıdır. 1869’da yayımlanan Maarif Nizamnamesi’ni müteakip imparatorluk topraklarının dört bir tarafında yeni rüşdiye mektepleri kurulmuştur. Bu mekteplerden bir tanesi de 1892’de eğitim-öğretime başlayan Akçaâbad Rüşdiye Mektebi’dir. Akçabaad Rüşdiye Mektebi’nin kuruluşu ve gelişimi, mektepte okutulan dersler, öğrenci ve öğretmenlerin nitelik, nicelik ve karşılaştıkları sorunlar bu çalışmanın temel problematiğini teşkil etmektedir. Çalışmanın temel amacı bu problematikler ekseninde Akçaâbad Rüşdiye Mektebi’ndeki eğitim-öğretim uygulama ve pratiğinin nasıl ortaya çıktığı ve gelişim gösterdiğini tespit etmektir. Çalışma çok yönlü bir araştırmayı gerekli kıldığından döneme ait arşiv vesikaları, devlet, vilayet ve maarif salnameleri, nizamnameler ve talimatnamelerde yer alan, mekteple ilgili dolaylı ve dolaysız bilgiler titizlikle incelenerek değerlendirilmiştir. Ayrıca incelenen dönem içerisinde eğitim-öğretim faaliyetlerinde tutulan kayıtlardan elde edilen veriler, çeşitli tablo ve grafiklerle gösterilmiş ve konu ile ilgili daha önce yapılan çalışmalarla da mukayese edilmiştir.

Deltas in the Cisco Group contain significant volumes of potential reservoir sandstones in the Late Pennsylvanian (Virgilian/Gzhelian) mixed siliciclastic-carbonate succession in the Eastern Shelf of the Permian Basin. While early studies predominantly supported a river-dominated model for these deltas, our findings establish the presence of tide-influenced deltas characterized by the following features: (i) predominant heterolithic lithology; (ii) diagnostic structures such as flaser bedding, bidirectional ripple cross-lamination, or double-mud drapes; (iii) an abundance of interpreted fluid muds; and (iv) elongated bars on the subaqueous platform. Through analysis of 290.2 m of core, we identify six (6) facies associations related to tide-influenced deltaic systems in highstand and falling-stage intervals of the proximal Eastern Shelf: lower-delta-plain/embayed tidal flat, distributary channel and distributary mouth bar/delta front deposits on the subaerial delta; subaqueous delta platform, subaqueou s delta foreset, and prodelta deposits on the subaqueous delta. Moreover, two (2) additional facies associations, transgressive shelf deposits, and subtidal shallow-water carbonates, record continuous episodic transgressions within the deltaic packages. Well-log cross sections reveal repetitive stacking of deltas, typical of icehouse systems, and sandstone mapping suggests elongated tidal bars forming the interpreted subaqueous delta platforms. These features suggest a compound clinoform morphology of the Cisco Group deltas akin to modern tide-influenced deltas that have carbonate banks such as the Gulf of Papua. This compound clinoform morphology has implications for the elongate geometry and isolation of sandstone reservoirs, impacting fluid migration and storage. Moreover, these insights extend beyond the Cisco Group to other Pennsylvanian and Permian levels on the Eastern Shelf, as well as to other deltas in mixed siliciclastic-carbonate systems in icehouse conditions.

The CEP approach combines chemical knowledge with entrepreneurial concepts. In the manufacture of macromolecular products, a deep understanding of chemistry is essential. Entrepreneurship education is very important because it raises enthusiasm and motivates students to start a business when they graduate from school. The research objective is to design practical instruction for Chemo-Entrepreneurship (CEP) focusing on the subject of macromolecules. The type of research used for the development of practical instructions in this study is Research and Development. The development method is ADDIE (Analysis, Design, Development, Implementation, and Evaluation). The product developed was validated by six validators in the valid category according to Aiken's V table with a validity value of 0.846. The research subjects in the product trial developed in this study were students of class XII MIPA SMAN 1 Cepu. The assessment of student responses was in the very good category with a percentage of 94.3%. It can be concluded that the CEP-practical guide is feasible to use. The resulting product is expected to be used as a learning resource on the macromolecule topic.

Cationic dyes are dyes containing amine derivatives that can be used on cellulose, protein, nylon, acrylic and synthetic fibers but these dyes are less fast in coloring. This study investigates the impact of Pb2+ heavy metal ions on cationic dye absorption utilizing molecularly imprinted polymers as adsorbents. Concentrations of Pb2+ ranging from 0 to 50 mg/L were examined. In a one-hour interaction, 50 mg of adsorbent was introduced into a solution containing 100 ppm methylene blue dye and Pb2+ with varying concentrations. Following centrifugation, the filtrate was collected, and dye concentration was measured using a visible light spectrophotometer. The sorption capacity of the dye with Pb2+ reached 41.22 mg/g at the highest concentration and 35.83 mg/g at the lowest. Notably, an inverse relationship was observed between Pb2+ concentration and absorption capacity, indicating a decrease as metal ion concentration increased, though stability was maintained. These findings contribute valuable insights into the nuanced dynamics of heavy metal ions and cationic dye absorption, shedding light on potential applications of molecularly imprinted polymers as effective adsorbents.
Формальные модели мета-аргументации и объективации дискуссий
Authors: Фролов Константин Геннадьевич
Published: July 2024

В статье представлено решение проблемы объективации дискуссий, которая ранее была сформулирована И.В. Берестовым. Под «объективацией» дискуссии понимается возможность использовать сложную структуру аргументации, состоящую из множества аргументов с определенным на нем отношением атаки, в качестве молекулярного аргумента в пользу или против некоторого тезиса. Проблема заключается в том, что при традиционном дунговском подходе к моделированию структуры аргументации в состав молекулярных аргументов могут входить лишь атомы, между которыми нет отношения атаки, что не позволяет собрать всю дискуссию в единый молекулярный аргумент. Мы показываем, как эта проблема может быть решена в рамках подхода Д. Габбая к моделированию мета-аргументации, в рамках которого всякое отношение атаки может быть «объективировано» путем введения в структуру графа дополнительных вершин.

Objective: Transforaminal percutaneous endoscopic discectomy (TPED) is a minimally invasive surgical procedure used to treat herniated disc fragments in the hidden zone of MacNab. This study aimed to investigate the efficacy, advantages, and safety of TPED for superiorly migrated lumbar disc herniation in the hidden zone of MacNab, focusing on patients with isolated causative factors such as prolapsed discs.Methods: A cohort of patients with clinical conditions involving isolated causative factors of herniated discs in the hidden zone of MacNab were selected for TPED. Patients with conditions contributing to clinical symptoms were excluded. Twelve patients with hidden-zone disc herniations underwent TPED. Under fluoroscopic guidance, precise skin markings were performed, followed by chromodiscography and epidurography. A nonstandard floating approach was utilized for TPED. The assessment of patients included visual analogue scale and Oswestry Disability Index scores. The outcomes were evaluated based on the modified MacNab criteria after 12 months.Results: Successful removal of the herniated fragments was achieved in all 12 cases of hidden-zone disc herniations that underwent TPED. According to the modified MacNab criteria, 11 out of 12 patients achieved excellent outcomes, while one patient attained a good outcome.Conclusions: The transforaminal approach in TPED was confirmed to be a highly effective and minimally invasive technique for managing hidden-zone disc herniations. The procedure yielded satisfactory to excellent results, accompanied by a significantly shorter rehabilitation period and minimal blood loss. Importantly, the pars interarticularis and lamina remain fully intact with the transforaminal approach.
