The war waged by the Russian state against independent Ukraine posed new difficult tasks for society in the production and repair of damaged military equipment. In the conditions of a shortage of military equipment, carrying out repairs becomes a task that must be performed quickly and efficiently in order to replenish the armed forces of the state.
In such difficult conditions, methods of high-speed processing should be used, including methods of surface strengthening of machine parts.
The work is devoted to the improvement of technological processes of restoration and strengthening of parts of automobile and military equipment at repair factories under conditions of martial law. The efficiency of auto repair production is determined by the number of parts that are restored and continue to perform their functions with even better indicators than before restoration.Most parts have a residual resource and can be reused as a result of carrying out a relatively small amount of work on their restoration. The main methods of surface strengthening of machine parts are chemical and thermal treatment (cementation, nitriding, nitrocementation), surface plastic deformation, application of electrolytic coatings and surface hardening - laser and induction using high frequency current. The processes of chemical and thermal treatment are long-term and are not relevant in repair production in wartime. Modern mobile repair workshops prefer equipment and tools that are not metal-intensive and are able to perform technological processes in a short period of time. The most expedient at present is the introduction of technological processes using installations that produce high-frequency current and processes based on it.In the work, the authors conducted research and developed an inductor for hardening the rocker arm made of steel 45. The choice of the type of inductor and its calculation are based on the relevant conditions described in the work.In the work, the authors conducted research and developed an inductor for hardening the rocker arm made of steel 45.

One of the most advanced directions in agriculture is precision agriculture, which is an integrated process of managing plant growth according to their needs. This technology has become possible due to the development of informatics, communication systems, and progress in the automation of agricultural machinery. A fundamental part of precision agriculture is the development and adaptation of strategies and practices for farming in modern conditions. The main focus is on measuring, understanding, and applying practical factors that affect plants, such as soil hydro-physical and chemical properties, landscape, seeds, applied technology, sowing and harvesting schedules, diseases and pests, weeds, and agro-climatic conditions.
The purpose of the work is to explore innovative, modern solutions, and development directions of the basic elements of precision agriculture systems that will contribute to making informed management decisions to ensure food security in agricultural production.
The work emphasizes that precision agriculture is considered an integral part of resource-saving ecological farming, involving the application of an integrated management system rather than individual separate elements. Thanks to the rapid development of information technologies based on innovative achievements in cybernetics, optics, sensor systems, laser and computer technology, satellite navigation systems, sensors of various purposes, and wireless communication means, solutions have been developed that integrate all elements of the agricultural machinery complex into a single whole. Among the modern solutions and development directions of precision agriculture systems are the application of satellite remote sensing with spatial resolution up to a few centimeters (GeoEye and WorldView); UAVs equipped with multispectral cameras, various sensors, satellite navigation systems, a small onboard computer, and equipment for chemical application; ground sensors designed for continuous (mobile) monitoring of plant and soil properties, such as nitrogen content, water stress, organic matter, and soil moisture (ISARIA, MiniVeg-N, and YARA N); and the use of systems such as Agronomic Decision-making Engine (ADE), See & Spray Ultimate, AiCPlus, SmartSprayer, etc.
It is noted that with the development of electronics and information technologies, various sensor systems have emerged, widely used in agricultural production to control the production process. To successfully implement precision agriculture technologies, reliable information about the soil, plants, the surrounding environment, and their variability in both space (within a field) and time is necessary.

The strength characteristics of multilayer textile materials are important indicators that affect their reliability and durability.
When gluing layers of materials, one of the fundamental properties of matter is used - adhesion. Adhesion relative to textile materials is to obtain a non -detachable connection of the textile cloth and the canvas of the base by establishing between them with glue when heated with plastic deformation and further cooling of all components.
During operation there is a displacement of layers relative to each other, as a result, the fabric is destroyed as a whole.
Therefore, the process of destruction of adhesive connection of layers of textile materials is a consistent deformation of the adhesive and protruding fibers of the fabric and the canvas of the base before displacement, deformation (elongation) or destruction.
The authors of the article investigated the influence of the mechanical properties of textile materials on the strength of the adhesive connection of layers of composite materials. A method of fabric strength research using mathematical modeling has been developed, which allows, without time-consuming experimental studies, to predict the loss of strength with known values ​​of the properties of fabric fibers, the number of layers, and the type of glue. On the basis of the theory of gluing of textile materials, theoretical and experimental studies of the strength of the adhesive connection of multilayer materials were carried out.
When studying the strength of an adhesive joint, the main indicator is the magnitude of forces during delamination.
The process of destruction of the adhesive connection of layers of textile materials in the event of a delamination load is considered as a sequential deformation of the glue with protruding fibers of the fabric and the base fabric until their displacement, deformation (elongation) or destruction.

This work is dedicated to the study of the energy efficiency of using electric heating systems in the classrooms of Ivano-Frankivsk National Technical University of Oil and Gas (IFNTUOG), where the actual state of heating systems and their efficiency in educational building №9 were determined. An experimental study was conducted, which included determining the heating and cooling time of working surfaces and the distribution of temperatures across them in a classroom; determining the distribution of thermal energy at several levels of the room.
Experimental data were obtained to evaluate the effectiveness of different electric heating systems in classrooms in standby mode, which allowed selecting the infrared heating system based on ceiling heaters as the most optimal technical solution for providing an acceptable level of comfort and energy efficiency. The effectiveness of using air thermostats for the electric heating system based on infrared heaters, which operates in standby mode, leading to excessive electricity consumption, was also studied.
The results confirm that the heating system using infrared panels ensures even heat distribution, maintains comfortable temperature and humidity conditions, and is distinguished by high energy efficiency. In contrast, the use of electric convectors with an inefficient water heating system does not provide adequate air heating, especially in spacious and high rooms, where heat dissipates quickly due to insufficient insulation.
The data obtained during the scientific research, along with previous studies, allow for the development of an automatic intelligent heating and ventilation control system that will use the most advanced research results in the field of efficient operation of engineering systems in educational institutions.

Метою статті є вивчення особливостей цих методів, вивчення технологічного процесу прийомів виробництва алюмінію, рівень переробки якого з кожним роком зростає. Алюміній присутній приблизно на 8 відсотках поверхні Землі. Вперше застосування алюмінію в промисловості почалося в 1886 році методом електролізу. Виробництво алюмінію шляхом переробки руди, що містить алюміній, називається первинною переробкою, а виробництво переробленого амулінію з використанням алюмінію, отриманого в результаті цієї переробки, називається переробкою. У той час як процес первинного виробництва алюмінію є процесом, який вимагає великих інвестицій і більше забруднює навколишнє середовище, переробка є процесом, який потребує менших витрат і завдає відносно низької шкоди навколишньому середовищу, що збільшує масштаби переробки алюмінію з кожним роком.
Теоретико-методологічною основою дослідження були проаналізовані способи переробки алюмінію та науково-дослідні роботи, що відображають технологічний процес цих методів і конкретні факти. Під час цього дослідження тема була ретельно досліджена з використанням методів математичного аналізу, малюнків, таблиць та графіків.
Головна висунута наукова інновація полягає в тому, що розвиток технології має першочергове значення для вдосконалення конкретних методів процесу переробки алюмінію, а вплив процесу переробки, який здійснюється за допомогою цих методів, на забруднення навколишнього середовища відбувається на нижчому рівні. . Падіння собівартості, у свою чергу, позначається на ціні виробів з алюмінію.
Результат дослідження:
- У великих країнах-споживачах вживаються ефективні заходи проти глобального потепління та викидів CO2, в результаті чого вторинна переробка, стійкість і скорочення промислових викидів все більше стають одними з пріоритетів на ринку товарів;
- За таких умов алюміній буде продовжувати виділятися як набагато кращий матеріал, ніж усі альтернативні матеріали, і його споживання зростатиме;
- Оскільки алюмінієвий сектор готується до цієї нової ери, сертифікація процесів переробки повинна підвищити його конкурентоспроможність шляхом розвитку його потужностей і технологій, а також сприяти чистому навколишньому середовищу.

In this work, a review of modern research in the field of increasing the corrosion-mechanical wear resistance of titanium alloys using glow discharge nitriding is carried out. Titanium alloys, due to their unique properties, namely high strength, lightness, exceptional corrosion resistance and excellent biocompatibility, are widely used in aviation, medicine, engineering and many other industries. However, operational conditions in some applications require even greater improvement of the wear resistance and corrosion resistance of these alloys, which makes the search for effective methods of their improvement an urgent scientific and engineering task.
Among the promising technologies that can be used to improve the corrosion-mechanical properties of titanium alloys, low-temperature anhydrous nitriding in a glow discharge should be considered. The use of low-temperature anhydrous nitriding in a glow discharge eliminates the growth of the base grain and hydrogen embrittlement of the surface. Also, low-temperature nitriding in a glow discharge makes it possible to increase the wear resistance of the surface of titanium alloys, while the saturation of the surface with nitrogen is controlled, which allows predicting the results of processing, does not lead to a change in the shape of parts.
The analysis of scientific research shows that increasing the corrosion-mechanical wear resistance of titanium alloys by means of nitriding in a glow discharge is a promising direction that opens up new opportunities for industry and science. Progress in this field depends on further research, innovative development and the integration of the latest technologies, which together will contribute to the creation of more durable, efficient and environmentally friendly materials for a wide range of applications.
In general, increasing the corrosion-mechanical resistance of titanium alloys by the method of nitriding in a glow discharge is a promising direction of research in Ukraine, which can lead to the improvement of the properties of titanium alloys and the expansion of their use in various industries.

This study evaluates sustainable transportation development in Batam City, focusing on the accessibility of public transportation for persons with disabilities as a sustainability indicator. Utilizing qualitative research methods, primary data were collected through interviews, complemented by secondary data from various sources such as Department of Transportation reports, Batam City Government documents, and online media. Data analysis employed triangulation, supported by Vosviewer Tools for processing secondary data. Findings reveal inadequate transportation accessibility services for people with disabilities in Batam City. Effectiveness, efficiency, adequacy, and equality for this demographic remain suboptimal, indicating a lack of sustainable and inclusive approaches. Regional regulations concerning disabilities are not fully implemented, and there's a lack of management strategies for transportation or Transport Demand Management tailored to assist people with disabilities. The Bus Rapid Transit (BRT) system's ineffectiveness hampers transportation connectivity, exacerbating access challenges. Essential disability facilities like ramps and bell signals are unevenly provided, while the limited number of special seats creates difficulties in prioritizing pregnant women and the elderly. Consequently, the current serviceability access falls short of meeting the standard needs of people with disabilities, as envisioned in Sustainable Transportation frameworks.

The era of society 5.0 has been entered by many developed countries. Indonesia, as a developing country, also has the same opportunity to enter the era of society 5.0. Therefore, an approach through the education system needs to be done, especially in preparing teachers in Indonesia. Millennial teachers born in 1981-2000 are future teachers and hope for Indonesia. They are the demographic bonus and the largest productive age group in Indonesia. This generation of teachers will face the education system in the era of society 5.0. This study explores the results of the self-reflection of millennial elementary school teachers on their readiness to face the education system in the period of society 5.0, specifically on technology mastery and students' understanding ability. Data were collected through unstructured interviews with 6 primary school teachers at millennial age in different schools to help them reflect on themselves and then analyzed using descriptive analysis. The results show that the readiness of elementary school teachers at the millennial age in terms of mastering technology is based on three self-conditions, namely self-confidence, the adaptability, and is relied on by colleagues. These three conditions of self in terms of mastery of technology are interconnected with each other. Meanwhile, in terms of student's ability to understand students, their self-readiness is based on two conditions, namely understanding one's own constraints in order to understand students and finding ways to relate to students. This research is limited to only two conditions, namely mastery of technology and the ability to understand students, which are included in teachers' pedagogic and professional competencies. This study also recommends several future teacher professional development research practices.

BACKGROUND: β-tricalcium phosphate (β-TCP) has been successfully utilized as a 3D printed ceramic scaffold in the repair of non-healing bone defects; however, it requires the addition of growth factors to augment its regenerative capacity. Synthetic bone mineral (SBM) is a novel and extrudable carbonate hydroxyapatite with ionic substitutions known to facilitate bone healing. However, its efficacy as a 3D printed scaffold for hard tissue defect repair has not been explored. OBJECTIVE: To evaluate the biocompatibility and cell viability of human osteoprecursor (hOP) cells seeded on 3D printed SBM scaffolds via in vitro analysis. METHODS: SBM and β-TCP scaffolds were fabricated via 3D printing and sintered at various temperatures. Scaffolds were then subject to qualitative cytotoxicity testing and cell proliferation experiments utilizing (hOP) cells. RESULTS: SBM scaffolds sintered at lower temperatures (600 °C and 700 °C) induced greater levels of acute cellular stress. At higher sintering temperatures (1100 °C), SBM scaffolds showed inferior cellular viability relative to β-TCP scaffolds sintered to the same temperature (1100 °C). However, qualitative analysis suggested that β-TCP presented no evidence of morphological change, while SBM 1100 °C showed few instances of acute cellular stress. CONCLUSION: Results demonstrate SBM may be a promising alternative to β-TCP for potential applications in bone tissue engineering.

Presently, the Real-time global payment system is suffered primarily by fraudsters based on customer behavior. For the identification of fraud, scientists used many techniques. However, identifying and tracking the customers infected by the fraud takes a significant amount of time. The proposed study employs pre-trained convolution neural network-based (CNN) architectures to find SFDT. CNN is pre-trained on the various network architectures using fraud data. This article contributed to pre-trained networks with newly developed versions ResNet152, DenseNet201, InceptionNetV4, and EfficientNetB7 by integrating the loss function to minimize the error. We run numerous experiments on large data set of credit payment transactions which are public in nature, to determine the high rate of SFDT with our model by comparing accuracy with other fraud detection methods and also proved best in evaluating minimum loss cost.

Authors: An Xuemei
Published: April 2024

Improving the quality of higher education teaching is a systematic project. The improvement and formulation of relevant laws, regulations, and measures at the macro level are the minimum and specific requirements for the overall private universities, and are the basic guarantee for controlling the healthy and orderly development of universities. At the micro level, school management needs to focus on two aspects: leadership level construction and teacher level construction. Only by scientifically controlling the above issues and comprehensively considering them can the persistent problem of low teaching quality be fundamentally and gradually solved. In short, the construction of the quality assurance and evaluation system for higher education teaching in China is still in the initial stage of development. Therefore, universities should start from the guarantee and evaluation system to promote the construction of teaching process monitoring and evaluation systems, and improve the level of education and teaching quality on the basis of highlighting higher education teaching reform and research. The teaching quality evaluation of higher education in the era of artificial intelligence is a MADM. In this study, in light with interval-valued intuitionistic fuzzy Hamacher interactive hybrid weighted geometric (IVIFHIHWG) technique and induced OWG (I-OWG) technique, the induced IVIFHIHWG (I-IVIFHIHWG) technique is administrated. Then, the I-IVIFHIHWG technique is exploited to manage the MADM under IVIFSs. Finally, the numerical example for teaching quality evaluation of higher education in the era of artificial intelligence is exploited to verify the I-IVIFHIHWG technique. Thus, the main research contributions are administrated: (1) the I-IVIFHIHWG technique is administrated in line with the IVIFHIHWG and I-OWG technique; (2) the I-IVIFHIHWG technique is exploited to manage the MADM under IVIFSs; (3) the numerical example for teaching quality evaluation of higher education in the era of artificial intelligence and some comparative studies were exploited to verify the I-IVIFHIHWG technique.
A novel LqROPF-Entropy-WASPAS group model based on Frank aggregation operators and improved score function in linguistic q-rung orthopair fuzzy framework
Authors: Verma Rajkumar
Published: April 2024

Decision analysis plays a crucial role in our everyday actions. Efficient decision-making models rely heavily on accurately representing human cognitive knowledge. The linguistic q-rung orthopair fuzzy sets (LqROPFSs) offer a versatile means of representing qualitative cognitive information by adapting the parameter q to different scenarios. This study presents a novel scoring function to rank linguistic q-rung orthopair fuzzy numbers (LqROPFNs) with greater precision compared to the current score function. Next, we present novel arithmetic/geometric aggregation operators (AOs) that utilize new Frank operational rules to combine a finite collection of LqROPFNs. The work also examines the several desirable characteristics and special cases of the provided AOs. Furthermore, a novel decision-making model called the LqROPF-Entropy-WASPAS model has been introduced to address the challenges of multiple attribute group decision-making (MAGDM) problems in a linguistic q-rung orthopair fuzzy environment. The model incorporates proposed AOs and a scoring function. The suggested methodology is exemplified by considering a practical decision to select an online teaching platform. The validity of the results is confirmed through an extensive sensitivity analysis and comparative investigation employing various existing MAGDM approaches within the linguistic q-rung orthopair fuzzy framework. The proposed approach offers enhanced flexibility to decision experts, empowering them to analyze decision outcomes across diverse scenarios. This flexibility is achieved by allowing the manipulation of values associated with various parameters, enabling decision-makers to tailor the analysis according to their specific attitudes and requirements. This adaptability ensures a more advanced and personalized analysis of decision outcomes, accommodating decision experts’ distinct viewpoints and preferences in varying situations.

Published: April 2024

BACKGROUND: Musculoskeletal disorders are leading causes for long sickness absences and early retirement. Dental work is physically strenuous, and many studies have shown a relation between work-related MSDs and dentistry. However, fewer studies have focused on how these conditions affect the work ability of dentists. OBJECTIVE: This study aimed to reveal the relationship between MSD, work ability and sickness absences in Finnish dentists and dental students. METHODS: A questionnaire was sent to 1200 dental workers and students. It inquired of age, gender, use of dental loupes, physical exercise, use of health care, and site, length and frequency of musculoskeletal complaints. Work ability was assessed with four parameters: work ability score (WAS), future work ability (FWA), self-estimation of MSD-related work disability, and sickness absence days. RESULTS: The questionnaire gained 255 responses (response rate 21%). The majority (90%) of the respondents had experienced MSD during the past year but only eleven percent of them had been on sick leave. MSDs correlated significantly with WAS, FWA and MSD-related work disability. Results remained significant even age adjusted. Age was a strong predictor of declined work ability, but gender, physical exercise or dental loupe use did not have a significant impact. CONCLUSIONS: Despite all the ergonomic advances in modern dentistry, the occurrence of MSD symptoms is still high. MSDs seem to affect dentists’ work ability significantly, but amount of sickness absence is relatively low, which may indicate a high level of presenteeism.

BACKGROUND: The effects of traffic sign information volume (TSIV) on the visual characteristics and workload of novice and experienced drivers were investigated in this study. TSIV plays a crucial role in road traffic safety, and understanding its impact on drivers is essential for designing effective traffic sign systems. OBJECTIVE: This research aimed to compare the visual characteristics and workload of novice and experienced drivers under varying TSIV doses through simulated driving tests. The objective was to provide insights for optimizing the design of road TSIV. METHODS: Six TSIV levels were considered: S0, S1, S2, S3, S4, and S5, representing different workload levels. Participants, including both novice and experienced drivers, were involved in simulated driving scenarios with varying TSIV levels. Eye movement data was collected using an eye tracker device. The study was conducted in China, and appropriate driving simulators and equipment were utilized. RESULTS: The findings revealed several valuable results. Experienced drivers exhibited a higher proportion of saccade behavior in the 30–90 ms time period and did not show rapid saccade behavior during the 0–30 ms period, indicating superior visual search strategies. Both novice and experienced drivers demonstrated improved visual cognitive abilities at the S3 level of TSIV, which corresponds to normal and safe driving conditions. Furthermore, a majority of both groups had saccade amplitudes in the range of 0°–4°, with experienced drivers showing a slightly higher proportion. About 82% of experienced drivers had saccade behavior within the range of 0°–2°, compared to 75% of novice drivers. CONCLUSIONS: The study concludes that the S3 level of TSIV, corresponding to 30 bits/km, is optimal for both novice and experienced drivers. This level promotes better visual performance and reduces visual workload, indicating that drivers’ information acquisition capacity and visual search strategies are maximized while keeping the workload associated with driving at a minimum. These findings have significant implications for enhancing driving safety.

Authors: Tutu Samuel Kofi
Published: April 2024

There is a strong emphasis on achieving optimal health through nutrition by students, however, many students tend to care less about their nutritional requirements. A study was conducted to assess dietary practices and their effects on the academic performance of high school students in Ghana. The study hypothesized that dietary diversity has a significant influence on the academic performance of high school students. A cross-sectional analytical survey design was used. A sample of 800 students was randomly selected from five randomly selected senior high schools in Tamale Metropolis. A questionnaire was used for data collection. Descriptive statistics, Pearson correlation, t-test, and ANOVA at 0.05 probability level were used in the data analysis with SPSS computer software. The results indicated that breakfast was the most skipped meal, an average of three days a week. Dietary diversity was high among the students, 83.2% consumed six or more different groups of foods within the past 7 days. The majority of the students were from moderate (42.0%) and mild (32.8%) food insecure households. The age of the students, household size, and parents’ employment status significantly (p<0.05) affected the dietary diversity of the students. Higher dietary diversity was significantly (p<0.05) correlated with English language (r = 0.119) and social studies (r = 0.184) scores, while it had no significant relationship with mathematics and science scores. In conclusion, dietary diversity impacts the reading scores of students. Therefore, students must be diverse in their food intake for better performance.
