Authors: Бохонко Ірина , Хархаліс Тетяна
Published: January 2025

Використання інформаційних технологій є невід'ємною частиною функціонування сучасних підприємств, а попит на ІТ-продукти постійно зростає. Уміле застосування сучасних технологій дозволяє бізнесу вирішувати низку викликів, з якими він стикається в усьому світі. Підприємства Європейського Союзу та Сполучених Штатів уже активно використовують системи захисту та безпеки даних, автоматизовані системи моніторингу, штучний інтелект і хмарні технології. Водночас для розробки та впровадження інформаційних технологій потрібна зростаюча кількість ІТ-фахівців. Бізнес дедалі більше покладається на зовнішніх постачальників ІТ-послуг для підтримки своїх інформаційних систем і цифрових інновацій. Тому важливо підтримувати ІТ-підприємства в Україні та сприяти їхньому виходу на європейський ринок. Для розв'язання поставлених завдань було використано систему загальнонаукових методів дослідження. У дослідженні застосовувалися методи аналізу та синтезу, а також групування (для узагальнення послуг, необхідних підприємствам). Інформаційною базою дослідження стали нормативно-правові акти, міжнародні експертні дослідження та наукові праці вітчизняних і зарубіжних учених у сфері інформаційних технологій. Інформаційні технології є однією з найбільш динамічно зростаючих галузей в Україні, яка істотно впливає на економічний розвиток країни. Зі зростанням попиту на технологічні рішення як на внутрішньому, так і на міжнародному ринках, інвестування в ІТ в Україні стало стратегічно важливим напрямом, що пропонує значні можливості для розвитку як бізнесу, так і країни в цілому. У статті доведено, що глобальний попит на ІТ-продукти зростає, і бізнес готовий інвестувати в інноваційні рішення. Було виявлено, що найбільш затребуваними серед підприємств є комунікаційні та ІТ-послуги. У контексті глобалізації та цифрової трансформації інвестування в ІТ-сектор є стратегічним кроком для України, який не лише зміцнить економічні позиції країни на світовій арені, а й забезпечить сталий довгостроковий розвиток.

У статті визначено сутність економічної злочинності, особливості її поширення та загрози для держави і суспільства. Встановлено, що економічна злочинність є складним соціально-економічним явищем, що проявляється у вчиненні злочинних діянь та/або у веденні протиправної діяльності у фінансово-економічній сфері та має за мету отримання неправомірної вигоди. Виявлено значні зростаючі тренди щодо збільшення кількості економічних злочинів, особливо тих злочинів, що пов’язані із використанням бюджетних коштів та пов’язаних із корупцією. На підставі кореляційно-регресійного аналізу доведено вагомий негативний вплив економічної злочинності на рівень життя населення (коефіцієнт кореляції R^2=0,965) та на рівень бідності (коефіцієнт кореляції R^2=0,974). Доведено, що зростання кількості економічних злочинів обумовлює зниження рівня якості життя населення та зростання рівня бідності. Встановлено найбільш вагомий ступінь негативного впливу на рівень життя населення легалізації (відмивання) доходів, одержаних злочинним шляхом (коефіцієнт регресії r_1= –2,77) та злочинів, пов’язаних із ухиленням від сплати податків (коефіцієнт регресії r_5= –2,79). Проаналізовано можливості застосування економіко-математичних методів і моделей при оцінюванні впливу економічної злочинності на рівень життя населення в Україні та виявлено, що основною проблемою їх використання при оцінюванні взаємозв’язків та взаємовпливу між економічними явищами і процесами є проблеми, що пов’язані із висвітленням офіційною статистикою України даних, що характеризують параметри економічної злочинності, та становлять базу таких емпіричних досліджень. Обґрунтовано доцільність застосування економіко-математичних методів і моделей при оцінюванні впливу економічної злочинності на рівень життя населення в Україні та запропоновано їх використання в контексті формування системи заходів протидії економічній злочинності на національному рівні.

Published: January 2025

This study presents the investigation of hydrological drought in Myanmar’s Central Dry Zone using the Streamflow Drought Index (SDI) across various timescales (3, 6, 9, and 12 months) to assess its impact on water resources and agricultural productivity. The Central Dry Zone, which includes the Ayeyarwaddy River and encompasses the regions of Sagaing, Mandalay, and Magway, shows significant vulnerability of hydrological extremes due to its semi-arid climate and dependence on water resources. Monthly discharge data from selected hydrological stations from 1993 to 2022 is analyzed using DrinC 1.7 software to derive SDI values and drought characteristics. The results show that critical drought events in 2005-2006, 2013-2015, and 2019-2021 for all stations are marked by high severity and extended duration. Short-term SDI (SDI 3 and SDI 6) values capture rapid, intense droughts, while long-term SDI (SDI 9 and SDI 12) highlight extended water shortages. From this result, Monywa station shows the highest severity and duration of droughts across all SDI timescales compared to other stations. The results underscore the necessity of strategic water management and drought mitigation measures to protect agriculture and guide planning, establish early warning systems, and support sustainable development in the Central Dry Zone, Myanmar.

Authors: Abdulrazzaq Mortadha Kareem , Al-Abboodi Hamid , Zahra Hussein K. A. , Abood Taha Hassan , Abood Adnan Naama
Published: January 2025

The corrosion behavior of stud-welded AA5083-H321/AA6061-T6 joints was examined. The electrochemical demeanor of the resultant joint was scrutinized in 3.5% NaCl, ASTM seawater, and Na2SO4 solutions using scanning electron microscopy (SEM), optical microscopy (OM), energy-dispersive X-ray spectroscopy (EDX), and X-ray diffraction (XRD). COMSOL Multiphysics version 5.6 software was used to predict the galvanic corrosion of AA5083-H321/A6061-T6 in different solutions, using the software finite element (FE) kit. The results indicated that drawn arc stud welding (DASW) enhanced the corrosion resistance of the welding zone, with the highest resistance observed in the Na2SO4 solution. This process also influenced the pitting corrosion rate and minimized alterations in pit morphology, with the order of corrosion resistance decreasing from Na2SO4 to 3.5% NaCl and ASTM seawater. Among the base metals, the AA6061-T6 side of the weld exhibited superior corrosion resistance compared to the AA5083-H321 side across all tested solutions. The results from the numerical simulation of the corrosion behavior of the welded joint support the experimental assessment.

Evolution of Pervious Concrete Pavement at the Ministry of Transportation Ontario, Canada
Authors: Rhead David
Published: January 2025

As part of the Ministry of Transportation Ontario (MTO) drive to pursue innovation and have the “greenest” roads in North America, MTO is actively pursuing the use of pervious concrete pavement. Pervious concrete provides many environmental benefits and is recognized as a stormwater management best practice. There is also strong interest from the Ontario municipal sector, conservation authorities and “green” innovators in rapidly incorporating pervious concrete into their designs. The Ministry is currently investigating and trying to address concerns with pervious pavement durability, the potential for clogging, impact of traditional winter maintenance practices and users’ acceptance of surface finish. The Ministry of Transportation Ontario (MTO) has completed two pervious concrete commuter parking lots and is currently working on a third. Field performance, construction practices and test methods are being studied for their effectiveness. Based on MTO experiences to date, an Ontario Provincial Standard Specification has been developed. This paper summarizes the construction observations, lessons learned and laboratory performance data from the Ministry’s work to date.
Surface Stresses of Thick Concrete Pavement Slabs Due To Traffic Loads and Non-Linear Temperature Distributions.
Authors: Nishizawa Tatsuo , Ozeki Takato , Kawano Hirotaka
Published: January 2025

In this study, possibility of top-down cracking in concrete pavement was investigated. The main cause of the crack is supposed to be tensile stress at the top of the concrete slab. 3DFEM simulations that took into account actual temperature distributions throughout slab depth were performed on concrete pavements for a heavy duty road and an international airport. Thermal stress analysis revealed that nonlinear negative temperature distribution produces relatively large tensile stress at the top of the slab, which cannot be precisely estimated by conventional thermal stress equations based on the linear temperature distribution. Areas where the bottom surface of concrete slab was separated from the surface of underlying layer were very small, because the underlying layer deformed similarly as the slabs deformed and reduced the gap area. The combined stresses were also calculated with the application of both wheel and thermal loads. The maximum top combined stress occurred at a position away from the wheel loads. The ratio of the top combined stress in negative temperature gradient to the bottom combined stress in positive temperature gradient is greater in the airport pavement than that in the road pavement. The installation of dowels in joints reduced the combined stress in the loaded slab.
Development of Innovative Techniques for the Instrumentation of Composite and Wet on Wet Pavement Sections at MnROAD
Authors: Vandenbossche Julie M. , Barman Manik , Li Zichang , Adams Thomas S.
Published: January 2025

Composite and wet on wet concrete pavements are a promising solution for the economical, sustainable and durable construction and renewal of highways. Wet-onwet pavements consist of Portland cement concrete (PCC)-over-PCC, with a relatively thin PCC layer placed wet on a wet thicker layer made of a less expensive PCC mixture. A composite pavement here will be referred to as, a relatively thin hot mix asphalt (HMA) layer placed over a less expensive PCC mixture. In order to acquire knowledge on the performance of these pavements, three heavily instrumented pavement sections were constructed at the Minnesota Road Research Facility (MnROAD) in May 2010. The purpose of the instrumentation is to establish the magnitude of the environmental loads that develop within these pavements and the response of the pavement to both these environmental loads as we as traffic loads. Without this, the development of a rational mechanistic-empirical design process is not possible. The instrumentation of PCC pavements constructed in two lifts has never been performed before and presents a surmountable challenge. Discussed below are novel instrumentation techniques that were developed to overcome these challenges.
Long Term Performance of Sustainable Concrete Pavement Preservation Strategies in Canada
Authors: Kazmierowski Tom , Chan Susanne
Published: January 2025

Rigid pavement preservation and rehabilitation strategies for high traffic volume roads are important sustainable methods of extending the life of our concrete roadways. In 1989, the Ministry of Transportation of Ontario (MTO) undertook the rehabilitation of an exposed concrete pavement exhibiting various distresses. The existing pavement, originally constructed in 1963, consisted of 230 mm mesh reinforced Portland Cement Concrete (PCC) pavement with dowelled joints at a spacing of 21.3 m. The preservation strategies used on the northbound lanes, which had experienced moderate deterioration, consisted of using sustainable concrete pavement restoration (CPR) techniques, material specifications and construction methods, which included full depth repair, partial depth repair, diamond grinding and joint sealant replacement. The rehabilitation strategy selected for southbound lanes was a 180 mm thick plain jointed unbonded PCC overlay to address the severe 'D' cracking and spalling at all the joints and cracks. This paper will identify the sustainable concrete pavement preservation strategies using the pavement sustainability rating system – GreenPave. It will also discuss the pavement preservation strategies and their long term performance evaluation in terms of roughness measurements, frictional resistance measured, and pavement condition ratings. Overall, the 22 year performance of these preserved and rehabilitated concrete pavements has been good with acceptable levels of ride quality, frictional resistance and distress propagation.

Published: January 2025

Air pollution is a prominent critical issue of vehicles. The toxic pollutants are harmful to the environment, hazardous to human health and difficult to degrade by natural means. Therefore a significant amount of efforts have been done on road pavements that directly interact with vehicles. Basing on the synergetic effect of cement and titanium dioxide discovered in recent years new road pavements were developed. In particular, photocatalytic cementitious road materials can represent a key element to improve air quality, thanks to their ability to accelerate the natural reaction of oxidation. This paper deals with the development of several types of photocatalytic cementitious road pavements, such as paving blocks, asphalt concrete filled up with a photocatalytic slurry and concrete roads. Large laboratory and field-testing programs have been conducted measuring the environmental effectiveness by means of a specific set-up and in-situ sources, respectively. Functional and mechanical tests have also been performed on the materials studied to investigate their behavior under traffic loadings. Indeed, road pavements have to guarantee both de-polluting effects and performances usually required to a road pavement wearing course, according to the current Standards. The large research activity conducted till now clearly showed the significant contribution of such innovative materials to the improvement of air quality, reducing the nitrogen oxides concentration up to 60% in some local weather conditions. They can represent a new frontier of the research aimed at reducing air pollutants, for environmental friendly solutions. The findings underline the benefits of the inclusion of titanium dioxide in concrete pavements.
Rigid Pavement Backcalculation Using Differential Evolution
Authors: Gopalakrishnan Kasthurirangan , Ceylan Halil
Published: January 2025

The backcalculation of pavement layer moduli from Falling Weight Deflectometer (FWD) measured surface deflections is a challenging task. It can also be formulated as a global optimization problem with the objective of finding the optimal pavement layer moduli values that minimize the error between measured and computed surface deflections. Over the years, several backcalculation methodologies have been developed including the use of soft computing techniques such as Neural Networks (NNs), Genetic Algorithms (GAs), etc. In this paper, Differential Evolution (DE), a stochastic parallel direct search evolution strategy optimization method is integrated with rapid surrogate mapping of Finite Element (FE) solutions through Neural Networks (NNs) in developing an automated rigid pavement backcalculation toolbox.
COPS – concrete with open porous surface
Authors: Breitenbücher R. , Schulte-Schrepping C.
Published: January 2025

Tire-road noise is the dominating sound source in road traffic. Therein, the airpumping effect, the horn effect and the groove resonances assume an essential role within the noise development. Currently, the reduction of sound emissions from the concrete pavements is achieved by a sufficient surface roughness. In Germany, this is realized by the standard construction method with exposed aggregate concrete. In addition to the defined surface textures, it is also possible to produce an upper thin concrete layer with a near surface macro pore system accessible to the sound pressure. A high sound absorption can be achieved through the interconnected macro pore system in the near surface area.

Published: January 2025

The main purpose of this experiment is to confirm that unit water content in concrete do not increase after spraying on economical cellular sprayed concrete using silica fume and foam for the high strength and high quality of concrete for high performance. It can also use 2LCP process easily because of the use a batch plant. It is confirmed that increasing liquidity by generating foam makes the slump loss slower and it may help to solve the problem of construction delays. Finally, in this experiment the unit water content decreases due to the reduction of water during spray, adding water for producing foam doesn’t have a great effect on durability such as dry shrinkage and freeze-thaw resistance etc. From the result it is concluded that the foam disappeared entirely after sprayed.

Published: January 2025

This paper looks at the elements that are needed to implement an effective quality assurance program for a concrete paving operation. In this paper, the authors argue that the benefit of a good quality assurance program far outweighs the costs associated with it for both the agency and the contractor. New technologies are described that can provide information that allow monitoring of the properties critical to pavement longevity. Many are nondestructive and thereby reduce quality control costs compared to traditional monitoring tests. The intent of this paper is to show how a good quality assurance program could benefit both the contractor and the agency without adding significant cost.
Age-Dependent Flexural Properties of Fiber Reinforced Concrete Used in Thin Overlays
Authors: Kim Min Ook , Bordelon Amanda
Published: January 2025

This paper presents measured age-dependent flexural properties of fiber-reinforced concrete (FRC) as are used in the design of thin overlay pavements. A laboratory investigation was performed to quantify the pavement design properties, particularly residual strength ratio of FRC as a function of age. Four different types of structural macro-fibers, made of steel or polypropylene, and of different lengths or aspect ratios were investigated. Also different fiber volume contents from 0%, 0.5%, and 1.0% were studied for all fiber types and ages. The results confirmed that there is a significant agedependency to the residual strength ratio. The short steel FRC at high fiber volume content was the only mixture which showed constant residual strength ratio as a function of time. All other FRC mixtures exhibited a reduced residual strength ratio when tested at later ages.
Best Practices for Concrete Pavements – Technical Briefs by Federal Highway Administration
Authors: Tyson Samuel S.
Published: January 2025

The Federal Highway Administration (FHWA) and the American Association of State Highway and Transportation Officials routinely work to develop and deploy best practices for pavements. Technology transfer to the highway community has led to a better understanding of the multitude of factors that affect pavement performance and to a more accurate prediction of service life. One of the ways that FHWA addresses the need for technology transfer to highway engineers, consultants and contractors is through documentation of best practices in an accessible and easily readable format. This has resulted in the development and publication of “technical briefs” to address specific best-practices topics. These technical briefs are published online by FHWA and can be read and downloaded at no cost by anyone worldwide. This paper describes a series of recently published technical briefs that are focused on best practices for concrete pavements.
RECENT DEVELOPMENTS IN THE DESIGN AND CONSTRUCTION OF CONCRETE PAVEMENTS FOR GERMAN EXPRESSWAYS (AUTOBAHNS)
Authors: Springenschmid Rupert , Fleischer Walter
Published: January 2025

In Germany, concrete pavements have proven successful for heavy-traffic expressways (axle loads of from 11.5 to 13 t). Their surface offers durable good skidding resistance and develops little noise. Their service life is 25 to 40 years. Old concrete pavements are recycled into crushed aggregates for new pavement concrete or crushed aggregate base courses. The concrete pave- ments are produced without expansion joints or reinforcement. Transverse joints are arranged every 5 m. Transverse joints are doweled, and longitudinal joints are anchored using tie-bars. Concrete pavements for the highest traffic loads are 260 mm thick if they are placed on a ce- ment-bound base, and 300 mm thick if placed directly on a crushed aggregate base. Slipform pavers are used to place the concrete, normally in two layers.

This paper presents the results of finite element modeling of misaligned dowels. It shows that uniformly misaligned dowels perform similar to perfectly aligned dowels. On the other hand, non-uniformly misaligned dowels may cause joint lock-up and significant stresses in the surrounding concrete, which may lead to premature joint failure and reduce pavement life.

Published: January 2025

The analysis and study of foreign policy activities in modern conditions are associated with a wide pluralism of scientific approaches, in which the main attention is focused on factors of various nature, as well as a variety of interpretations of common key concepts, one of which is “foreign policy strategy”. An analysis of the practice of using the concept of “foreign policy strategy” reveals two approaches to its definition. In the first approach, the strategy is considered as a plan or concept of action, in the second - as a purposeful activity. Within the framework of the second approach, which seems to be more productive and promising, as well as corresponding to the national scientific tradition, the author’s version of the definition of this concept and its correlation with such definitions as “foreign policy course”, “foreign policy program” is proposed. The main content of the foreign policy strategy is revealed through the categories of “goals” and “means”, which provides additional opportunities for the study of foreign policy activities, the description and classification of its various forms, and also helps to reduce the diversity of definitions and their interpretations.

Authors:   Financial University under the Government of the Russian Federation, Moscow, Russian Federation, GARAGANOV A.V.
Published: January 2025

The article explores the historical development of artificial intelligence (AI) from the first technical developments to modern neural networks, analyzing its reflection in culture and cinema. The evolution of public perception is also considered through the prism of works of art, starting with mythological plots and ending with modern films. Based on the analysis of 58 popular films, four basic ideas about AI in the minds of residents of megacities have been identified: anthropomorphic robots (36.2%), intelligent systems (29.3%), technologically advanced humans (24.1%) and animated images (10.3%). Special attention is paid to the role of cinema in shaping public opinion about intelligent technologies and their impact on the development of a digital society. The study demonstrates the relationship between cultural perception of AI and real technological progress.

Published: January 2025

The purpose of the research. The article is dedicated to the formation of life strategies in capitals and provinces. Life goals are considered in relation to life meaning settings reflected in ideas about life success, factors of settings achievement, life values. There is considered life planning horizon, saturation and focusing of life plans of youth in capitals and provinces. Analyzed connection between youth’s ideas about the possibilities of achieving life goals and social feelings, influence of negative self-forecasting on the formation of pessimistic psychoemotional background and critical assessments of the situation in the country, negative attitude towards the authorities.

Results. The article shows that youth in capitals, compared to youth in provinces, is more critical of the external context of their life; it often looks at the circumstances of its own life through the prism of opportunities for development. It is more often focused on self-positioning in the "large society" and influencing it, and demonstrates an active subjective approach in achieving its goals. It is more often confident that it can achieve success, and doubts about it worsen the emotional background, increase criticality in relation to what is happening in the country and to the authorities. Youth in provinces perceives the general context and circumstances of its own life more positively, and is more often focused on goals related to the "small society". It is more dependent on external circumstances, more often ready for failure in life, but this does not cause it to feel negative about its own life or the external world. A conclusion is made about the possibilities of using the analysis of life strategies in studying the specifics of the formation of social and socio-political sentiments of representatives of different groups of youth. The empirical basis of the article is all-Russian surveys of FCTAS RAS.

The aim of the article is to identify similarities and differences in the articulation of program provisions and implementation of project practices of the largest political parties of the Union State of Belarus and Russia, “White Russia” and “United Russia”. The significance of the roles of the parties under study in the context of shaping the directions of development of public administration and civil society is revealed. The convergence of the contours of the formal organization of the party systems of the Russian Federation and the Republic of Belarus is emphasized, provided that the specific mechanisms of political participation of citizens, peculiar to the political systems of the states, are preserved. The conclusions are drawn about the similarity of essential parallels in the attitudes postulated by both parties regarding the commitment to the path of sovereign and independent development of states with the preservation of the identity of traditional values and foundations of culture, openness to constructive cooperation with respect to friendly states, strengthening of information and technological sovereignty. The analysis of the project practices of the parties allowed us to draw conclusions about the presence of substantive similarities and differences in a number of projects aimed at communication between the state and society in order to strengthen the prerequisites for the formation of civil patriotic identity. Special attention is paid to the status of the analyzed parties in the general structure of the party systems of Russia and Belarus.

Objective

The purpose of the study was to investigate the immediate and long-term effects of zero-drop running shoes on lower extremity joint biomechanics.

Methods

Seven male runners participated in this study (height: 1.74 ± 0.03 m, weight: 62.5 ± 3.1 kg, body mass index: 20.6 ± 0.7 kg/m2). Kinematic and kinetic data were collected when the participants ran at a speed of 13 ± 0.65 km/h in running shoes with zero and 15 mm drop both immediately and after the 8-week intervention wearing zero-drop running shoes. Paired t-tests were used to analyze the biomechanical differences between the different drop shoes in the immediate test and the biomechanical changes during the intervention.

Results

The foot strike index increased (zero-drop: p = 0.021, 15 mm drop: p = 0.049), along with the negative work of ankle joint (15 mm drop: p = 0.018), and the hip joint (zero-drop: p = 0.004, 15 mm drop: p = 0.009), while metatarsophalangeal joint negative work decreased (zero-drop: p = 0.029, 15 mm drop: p = 0.028) in post-intervention test compared to the pre-intervention test.

Conclusion

Zero-drop running shoes promote a forefoot strike pattern, which affects the distribution of lower extremity joint work.
