The politics of data infrastructures contestation: Perspectives for future research
Authors: Rone Julia
Published: March 2023

In our times of increasing screen dependency, the data infrastructures making possible ‘online’ or ‘virtual’ modalities of work and leisure have been increasingly contested. From the Netherlands to Ireland and Chile, activists have challenged the environmental consequences of energy- and water-intensive data centres, as well as the often undemocratic ways of deciding on their construction. In this piece, I draw on insights from the field of social movement studies to outline four key problems that can help us understand better the bottom-up infrastructural politics of screen media: (1) How can we explain the differential politicization of data infrastructures in various national contexts? (2) How do movements frame their resistance to data infrastructures? (3) How do we define success in the contestation of data infrastructures? (4) To what extent have we observed the transnationalization of data infrastructures contestation? These problems open up potential new directions for research that draws on comparisons and is attentive to diffusion processes across contexts.
Climate, infrastructure and the mediation of Miami: The spatial and discursive politics of the Network Access Point of the Americas
Authors: Schifani Allison M.
Published: March 2023

The Network Access Point of the Americas, housed in a massive 750,000 square foot structure in downtown Miami, is both data centre and internet exchange point, funnelling informational traffic from and among the United States, Central and South America and the Caribbean to more than 148 countries around the world. In addition to looking at it as a key piece of informational infrastructure, the analysis of the NAP presented in this article unpacks it as both a part of the built environment in Miami and a fantastic discursive production, a work of narrative-making in the city and the larger world. The ecocritical approach of this study includes a visual analysis of the NAP, a textual analysis of the promotional materials Equinix, its owner, produces about it and a situation of this data centre and internet exchange point within the development history and contemporary position of downtown Miami.
Traducción de textos budistas: una aproximación histórica, filosófica y filológica
Authors: Villamor Herrero Efraín
Published: March 2023

Desde tiempos védicos, «las palabras» fueron divinizadas ya que se creía que éstas representaban en total plenitud la realidad, en su nivel más trascendental. Las esperanzas puestas en lo que éstas pudieran significar y los numerosos prodigios metafísicos que se les atribuyeron, fueron objeto de debate también durante la transmisión del budismo por Asia. Las traducciones de los textos Mahāyāna se enfrentaron al antiguo desafío de usar las palabras como medio para transmitir una realidad superior mediante una nueva grafía: los ideogramas chinos. Influenciado por la filosofía śūnyatā 空 de Nāgārjuna 龍樹, este complejo proceso de traducción en el que las ideas podían preceder a los sonidos, derivó —como veremos en el análisis del Prajñāpāramitā-hṛdaya-sūtra— en el uso del antiguo recurso de recitación mántrica para deconstruir todo aquello que puede ser experimentado.
A Corpus-Based Study on the Spanish Translation of 道 (dao) in The Analects
Authors: Liu Zhao
Published: March 2023

This article has chosen seven Spanish translations of The Analects to conduct comparative research focusing on one culture-specific item, 道 (dao). Subscribed to a descriptive approach based mainly on norms postulated by Toury and Equivalence by Nida, it endeavors to answer the following research questions: 1) What are the main strategies in its translation? 2) What are the possible motivators of translation similarities and differences? This research combines quantitative and qualitative analysis methods based on corpus building. Corpus-based, this study describes the translation of 道 in Classical Chinese and its translation equivalence into Spanish. The findings demonstrated that various strategies and words are used to translate 道. When it functions as a verb, the literal translation is used, and different verbs are employed to express the meaning given the context. Moreover, decisions on verb tense, sentence structure, and grammatical subject also seem to vary significantly across translators. When 道 is used as a noun, translators show different preferences for word choices. Instances for both dynamic and formal equivalence have been observed, pointing out that these two concepts should not be analyzed in isolation, as they stand in a dynamic relationship. Translators also make adaptations to reach adequacy and acceptability in translation. Detailed results are discussed in light of these theories, and this study views translation as a socio, linguistic, cultural, and translator-based activity.

Published: March 2023

Background Sepsis is a leading cause of pediatric morbidity and mortality. The prevalence of sepsis mortality in Indonesia varies between 22.5 to 52%.

Objective To identify the clinical criteria for predicting sepsis mortality and evaluate the performance of the PELOD-2 score.

Methods This retrospective cohort study included pediatric patients admitted to the emergency department or pediatric intensive care unit (PICU) of Cipto Mangunkusumo Hospital, Jakarta, Indonesia, from January 2015 to May 2020. Demographic characteristics (age and sex), clinical manifestations [nutritional status, presence of shock, need for intubation, source of infection, inotrope use, mean arterial pressure, pulse rate, respiratory rate, and Glasgow Coma Scale (GCS) score], laboratory [leukocyte, platelet, neutrophil, and lymphocyte counts, neutrophil-to-lymphocyte count ratio (NLCR), procalcitonin, C-reactive protein (CRP), and lactate profile], PELOD-2 score, and mortality data were recorded as outcomes.

Results We analyzed data from 241 sepsis subjects. The overall mortality rate was 65%. Shock [OR 3.2 (95%CI 1.80 to -5.55, P<0.001)], GCS <9 [OR 2.4 (95%CI 1.30 to 4.23, P=0.005)],  inotrope use [OR 3.1 (95%CI 1.74 to 5.5, P<0.001)], CRP >33.5 mg/L [OR 2.5 (95%CI 1.14  to 5.35, P=0.02)], and lactate level >2.85 [OR 2.1 (95%CI 1.02 to 4.56, P=0.04)] were considered significant predictors of mortality. A PELOD-2 cut-off score of >8 had optimal sensitivity (81.2%) and specificity (72.9%) to predict mortality, with an OR of 11.6 (95%CI 5.72 to 23.5, P<0.001).

Conclusion Shock, GCS score, inotrope use, CRP, and lactate level can serve as clinical biomarkers to predict mortality in pediatric sepsis. A PELOD-2 score of >8 can predict mortality with reasonably good sensitivity and specificity.

In recent years the educational system has opted to implement sustainable strategies that allow access, coverage, relevance, and quality of education. The University does not escape these realities combined and the need to generate a real impact on all its stakeholders. Thus, the challenge of training competent individuals to face the future is increasingly relevant. This research aims to reflect theoretically on the impact that Sustainable Development and Social Responsibility effectively have on quality university education. For which relevant theoretical elements have developed that support in the first instance the origins of sustainable development and social responsibility and the fundamental elements of each one of them and, in the second instance, it explains how these binomial favors quality, sustainable and relevant education. The method is served from the qualitative paradigm, documentary observation, and content analysis. Among the findings, it is found that education influences people and nations, which is why Universities must take on the challenge of responsible teaching. It is concluded that today higher education institutions are called to the teaching of excellence. In particular, training future specialists in the tourism and hospitality industry requires the approach when it is not enough to carry out substantive functions of the University: teaching, research, extension, and social projection, but they must be articulated with each other, to contextualize the student of the problems of the environment, sustainable development of the territory and how they can be solved.
Interrelationship between Three Dimensions of Sustainable Performance Measurement among Malaysian Manufacturing Companies

Published: March 2023

Corporate financial responsibility is the sole driving force of business in the business sector, as the primary goals of a firm are to maximize profit and grow shareholder value. However, in the previous decade, larger corporate obligations have been recognized, including environmental, local community, working conditions, and ethical standards. With the rise of "sustainability" reasons, unprecedented climate change is being measured into corporate strategy in the direction of sustainable thinking. The triple bottom line (TBL) is a sustainability assessment that combines environmental and social factors in addition to profitability and the rate of return on investment. The purpose of this research is to look into the interrelationships between the three dimensions of sustainable performance measurement (SPM) in Malaysian manufacturing companies. A questionnaire is issued to 600 manufacturing companies in the Federation of Malaysian Manufacturers (FMM) as part of a quantitative data collection approach. All the proposed hypotheses are supported, thus showing the interrelationship between three dimensions of SPM existed. Consequently, Malaysian companies are lagging behind in terms of SPM’s adoption compared to developed countries. Because of that, more government efforts to facilitate the adoption of SPM practice among companies are needed. The sole focus on the manufacturing industry, accuracy of data collection and time constraint are the limitations of this study. Therefore, it is suggested that further research should explore more the interrelationship between the three dimensions of SPM.

Published: March 2023

The objectives of this research were to study the general information of the tourists and the factors affecting the decision of tourists and to assess the economic valuation of the Ayutthaya Historical Park, Thailand. A questionnaire was used to collect data from 400 tourists. The general information of tourists was analyzed using the frequency and percentage. The relationship between the economic and social factors and the visiting ratio was analyzed, as well as the economic valuation assessment of the Ayutthaya Historical Park that was analyzed with the Individual Travel Cost Method (ITCM). The research results indicated that most traveled to experience the arts and culture and make merit. The tourists were impressed with the beautiful ancient remains, which were the arts of Ayutthaya and the peace of the Park. Furthermore, the most influential factors affecting the decision to visit the Ayutthaya Historical Park that had statistical significance were the travel cost and distance. The findings obtained from the economic valuation assessment of the Ayutthaya Historical Park applying the ITCM showed that the consumer surplus was 1,508.40 Baht/person/time, while the economic valuation of the Ayutthaya Historical Park was 1,999,500,930.91 Baht/year. The average visit was 2.61 times per year.
Enhancements in formal process description by using a formal method
Authors: Xin Cheng , Grunau Lukas , Thron Mario , Riedl Matthias
Published: March 2023

To facilitate the planning of product processes, the Formalized Process Description (FPD) model was proposed. It enables users to graphically describe the requirements of a production process. However, the FPD model has limits. To overcome these limits, this paper describes an extension of the FPD model, which is called the Extended FPD model. The objects in the Extended FPD model are assigned types and logical statements to represent their specifications. Hence, the expressive power of the FPD model is enhanced. In this paper, a formal definition of the Extended FPD model is also presented. Based on this definition, a set of rules is defined to detect the contradictions automatically in the Extended FPD model. In addition, the description of requirements by using the Extended FPD model can also enable the integration of more formal verification methods.

Published: March 2023

Ferritin is an endogenous protein which is self-assembled by 24 subunits into a highly uniform nanocage structure. Due to the drug-encapsulating ability in the hollow inner cavity and abundant modification sites on the outer surface, ferritin nanocage has been demonstrated great potential to become a multi-functional nanomedicine platform. Its good biocompatibility, low toxicity and immunogenicity, intrinsic tumor-targeting ability, high stability, low cost and massive production, together make ferritin nanocage stand out from other nanocarriers. In this review, we summarized ferritin-based nanomedicine in field of disease diagnosis, treatment and prevention. The different types of drugs to be loaded in ferritin, as well as drug-loading methods were classified. The strategies for site-specific and non-specific functional modification of ferritin were investigated, then the application of ferritin for disease imaging, drug delivery and vaccine development were discussed. Finally, the challenges restricting the clinical translation of ferritin-based nanomedicines were analyzed.

New silicate-germanates (K2.9Cs0.1)(Sc0.7In0.3)[(Si2.95Ge0.05)O9]·H2O and (K2.16Cs0.84)Bi[(Si0.5Ge0.5)3O9]·H2O have been synthesized in multi-component systems under mild hydrothermal conditions. The new compounds are classified as new representatives of close related K3ScSi3O9·H2O parent structure, sp. gr. Pmn21. Their structural and isomorphic peculiarities are compared with it as well as with earlier investigated K1.46Pb1.54Сa[(Ge0.23Si0.77)3O9](ОН)0.54·0.46Н2О. Together with other known compounds, silicate-germanates form the extensive family A3M[T3O9]·H2O, A = K, Cs, Ca, Pb; M = Ho, Sc, Lu, Tb, Er, Y, Bi, Pb, In; T = Si, Ge, with a mixed microporous framework combined of M-octahedra and T-tetrahedra. Large alkali metal or/and Ca, Pb cations fill broad framework channels with cross-section up to 7.3 Å. Because of wide isomorphic substitution in the channels, and in tetrahedra and octahedra, ion exchange properties in the family are expected. Due to polar symmetry, all the crystals possess second-order nonlinearity which was confirmed with positive SHG tests for four compositions. Powder SHG experiments demonstrated moderate second harmonic intensities of order of α-quartz standard signals.

Published: March 2023

A metastable polymorph of Ti3Sn (called c-Ti3Sn) exhibiting the cubic Cr3Si-type structure was prepared by a mechanochemical route. At temperatures of about 450 °C, it transforms to the well-known hexagonal phase (Ni3Sn type, called h-Ti3Sn). 0.5% of iron was incorporated into the material originating from the steel beaker and the steel balls. However, quantum-chemical calculations show that this should not lead to a stabilization of the Cr3Si type. c-Ti3Sn shows a single signal at an isomer shift of δ = 1.70(1) mm s−1 in its 119Sn Mössbauer spectrum at 78 K.

Published: March 2023

Butanol was produced from pretreated deoiled rice bran (DRB) in a batch culture of Clostridium acetobutylicum YM1. The DRB was pretreated by acetyl chloride to produce fermentable sugars prior to butanol fermentation. Pretreatment of DRB using 1% acetyl chloride (AC-DRB) resulted in sufficient fermentable sugars (30.88 g/L), which was comparable to that produced by using 1% sulfuric acid (33.5 g/L). Pretreated AC-DRB contained 18.08 g/L glucose, 9.95 g/L xylose, and 2.86 g/L cellobiose. Detoxification of AC-DRB was performed to remove the fermentation inhibitors, such as furfural, 5-hydroxymethyl furfural (HMF), acetic acid, formic acid, and levulinic acid with the removal efficiencies of 92.98%, 98.82%, 51.53%, 38.72%, and 96.21%, respectively, using charcoal. The detoxification with charcoal was more efficient compared to that with XAD-4 resin. Acetone-butanol-ethanol (ABE) fermentation of detoxified AC-DRB (with 1% AC) by XAD-4 produced 5.64 g/L butanol, while detoxification with charcoal of AC-DRB (with 1% AC) produced 6.48 g/L butanol. In detoxified AC-DRB with charcoal, the maximum butanol and ABE yield of 6.48 g/L and 11.82 g/L, respectively, were achieved. This study is the first reported treatment of biomass using acetyl chloride, which was used as a pretreatment method for successful butanol production.

Several different methods for the extraction, separation, and purification of wood constituents were combined in this work as a unified process with the purpose of achieving a high overall efficiency of material extraction and utilization. This study aimed to present a laboratory-scale demonstrator biorefinery that illustrated how the different wood constituents could be separated from the wood matrix for later use in the production of new bio-based materials and chemicals by combining several approaches. This study builds on several publications and ongoing activities within the Wallenberg Wood Science Center (WWSC) in Sweden on the theme “From wood to material components.” Combining the approaches developed in these WWSC projects – including mild steam explosion, membrane and chromatographic separation, enzymatic treatment and leaching, ionic liquid extraction, and fractionation together with Kraft pulping – formed an outline for a complete materials-biorefinery. The process steps involved were tested as integral steps in a linked process. The scale of operations ranged from the kilogram-scale to the gram-scale. The feasibility and efficiency of these process steps in a biorefinery system were assessed, based on the data, beginning with whole wood.

У переднерестовий період зареєстровано значно менший вміст сумарних ліпідів у печінці порівняно з нагульним періодом, але значно більший вміст глікогену. Проте наявні енергетичні ресурси організму, на наш погляд, достатні для забезпечення пластичного та генеративного обміну, пов’язаного з трофоплазматичним ростом ооцитів напередодні початку нересту. Отримані результати можуть свідчити про оптимальні екологічні умови і достатній рівень розвитку кормових об’єктів у водному середовищі Кременчуцького водосховища, які забезпечують високий рівень перебігу метаболічних процесів в організмі статевозрілих особин судака у нагульний та переднерестовий періоди річного циклу.
Potential trends in invasion risk of the yellow-legged hornet, Vespa velutina, in Ukraine
Authors: Tytar V.M. , Kozynenko I.I
Published: March 2023

In the recent decade an alarming problem has risen about the invasion of Vespa velutina Lepeletier, 1836 (Hymenoptera: Vespidae) in European ecosystems. The species can cause serious damage to ecosystem biodiversity and in areas where it has been introduced, and can have serious impacts over beekeeping. Bioclimatic modelling suggests that under current climate conditions representatives of the invasive species have chances in the near term to invade a number of regions in Ukraine, especially in the west of the country, including Transcarpathia, and Crimea. Under predicted climate change the hornet will most likely extend its presence in Ukraine.
Conceptual issues and stages of establishment of military chaplainty in independent Ukraine
Authors: SAGAN Oleksandr , HARAT Ivan
Published: March 2023

The formation of the chaplaincy movement in the context of the formation of independent Ukraine (after 1991) required the solution of a number of issues, primarily of a conceptual nature. The initiators of the restoration of chaplaincy faced the underestimation of the chaplaincy factor, the risks of transferring interfaith disputes to the military environment. In fact, it was a question of finding their own model of chaplaincy service, which would provide an optimal model for organizing the work of chaplains. The authors propose to divide the development of the chaplaincy movement in independent Ukraine into three stages, which differ not only chronologically but also in their characteristics. The first stage (1991-2005) was characterized by a rethinking of the role and place of religion in the activities of the Armed Forces of Ukraine. The idea of a chaplaincy service was revived primarily on the basis of the volunteer movement. Volunteers also encouraged churches to form appropriate structures that would be responsible for chaplaincy work. At this stage, the driving force behind the formation of the chaplaincy movement was the unstable informal ties between church and security forces in Ukraine. With the advent of the first legal acts that regulated the search for optimal models for creating the chaplaincy institute, the second stage of development of the chaplaincy movement in Ukraine began. It lasted from 2006 to 2013. During this time, regulations were developed and implemented that institutionalized the relationship between the Ministry of Defense of Ukraine and the country's largest churches and religious organizations. The third stage began with the beginning of the Russian Federation's attack on Ukraine in 2014 and continues to this day. The annexation of Crimea and the outbreak of hostilities in eastern Ukraine created the need to sharply increase the number of chaplains and to legalize them in military institutions. Already in 2015-2016, the formation of the state regulatory framework of the chaplaincy institute began and staff positions of chaplains in military units were introduced. On the other hand, there has also been a qualitative growth in the theoretical and practical training of chaplains and their material support. These processes show that the establishment of the institute of military chaplaincy in Ukraine has actually taken place. In each period, the authors highlight the problematic issues that government agencies and religious organizations addressed in organizing the chaplaincy movement. Particular attention was paid to the attempts of activists to form their own model of chaplaincy ministry and the problematic issues of improving the quality of chaplains' training. In particular, it was pointed out that the best way for Ukraine is to organize separate chaplaincy faculties in the country's higher educational institutions to train specialists at the level of world standards.

Published: March 2023

Introduction: Worldwide, expanding human activities continue to be a threat to many large-bodied species, including jaguars. As these activities continue, it is critical to understand how home range sizes will be impacted by human-modified landscapes. Objective: To evaluate the importance of protected and unprotected land on home-range size across their range. Methods: We used home range data from 117 jaguars in several habitat protection categories and human biome types. We used a Generalized Linear Mixed Model to test home range and spatial overlap with conservation categories and human biomes. Results: Most home-ranges were in Jaguar Conservation Units (62 %), followed by Protected Areas (21 %), Indigenous People's Lands (10 %) and Jaguar Movement Corridors (3 %), where 76 % of the jaguars lived inside one the first three conservation types. However, outside of conserved land, Rangeland, Cropland, Seminatural land and other human biomes were also important (24 % of the individuals). Jaguars in Rangeland, Cropland and Seminatural land had the largest home ranges. Conclusions: Although conservation land was dominant, human-impacted lands appear to play a considerable role in satisfying the spatial requirements of jaguars.

Fluid catalytic cracking (FCC) is a method of cracking vegetable oils into simpler fractions and green fuel oils. One component of the FCC system is the FCC furnace. The FCC furnace is where the combustion process occurs and provides high heat transfer throughout the FCC system, especially for heating the reactor. The reactor temperature is the catalyst cracking temperature. The cracking temperature of the catalyst depends on the feed oil used in the cracking process, such as crude palm oil at 450‒550 °C or crude bio-oil at 300 °C. The fuel for heating an FCC furnace is usually coal. To reduce coal, we use a mixture of Azolla microphylla biomass with biochar and bio-oil from goat manure. The aim of this study was to analyze the mixture of Azolla microphylla biomass with biochar and bio-oil from goat manure to obtain sufficient furnace temperature to heat the FCC reactor, perform analytical calculations to obtain the volume of flue gas formed from the combustion reaction. We conducted two experiments; the first experiment used a mixture of 1 kg of Goat Manure Biochar (GMBC) with 0.5 kg of Azolla microphylla and the second experiment used a mixture of one kg of GMBC with 0.5 kg of Azolla microphylla plus 300 ml of Goat Manure Bio-oil (GMBO). A fuel mixture of one kilogram GMBC with 0.5 kg Azolla is not effective in combustion because the maximum temperature in the furnace is 177 °C but the fuel mixture of one kg GMBC, 0.5 kg Azolla and 300 ml GMBO has a furnace temperature of 472.75 °C, which can heat the stripper up to 313.25 °C so that cracking can occur in the raw bio-oil. Analysis of combustion results showed an increase in total CO2 volume from experiment one and experiment two of 0.966

Published: March 2023

The IT industry occupies a significant place in the economy of the world. Trends in its development directly affect changes in various sectors of the economy.
This paper considers the dynamics of IT industry under conditions of increased entropy of the functioning environment caused by crises, military conflicts, non-standard events. The mathematical basis of the study is an apparatus of fuzzy logic.
The proposed technique for analyzing and forecasting the state and dynamics of the IT sector makes it possible to take into account the influences of a set of factors of different nature and direction of action, which contributes to obtaining a reasonable assessment under conditions of inaccurate information. The software platform for implementing the methodology is the authentically designed fuzzy expert system (ES) FuzzyKIDE.
The conceptual foundations of the platform structure have been defined. A modification of the fuzzy inference mechanism has been proposed, which, unlike existing samples, makes it possible to eliminate saving intermediate results and reduces the load on the database. The composition and structure of the knowledge base (KB) for ES have been proposed. Fuzzy rules are based on predetermined relationships between key factors of influence. The technology of ES operation is represented using simulated scenarios with obtaining predictive results. The analysis of the final data of expert consultations proves the ES operability, providing for the possibility of KB significant expansion in the process of industrial operation. The use of ES is aimed at forming a holistic view of possible directions of IT sector development. Maintaining the actual state of ES KB is a condition for early warning of the emergent negative/crisis phenomena.
The FuzzyKIDE expert consulting system is proposed as a tool to support management decision-making based on the analysis and forecasting of the state and dynamics of IT sector under conditions of high uncertainty

Based on organoleptic and physical-chemical studies, it was established that the best option in the manufacture of "Mozzarella Ukrainian" cheese is to add to the normalized mixture before its pasteurization of the "Immunocort" supplement in the amount of 3 % by weight of the normalized mixture.
A study was conducted on the effect of the coagulation temperature and pasteurization temperature on the synergistic properties of the cheese clot. These indicators confirmed the significant importance for the transition of solids into whey in the process of making rennet cheese "Mozzarella Ukrainian" with the bio additive "Immunocort". It was found that with an increase in temperature, there was a decrease in the syneretic ability of cheese clots. The efficiency of using solids increased with increasing pasteurization temperature. The relatively low content of dry substances in whey at high pasteurization temperatures can be explained by the denaturation of whey proteins and their transition to a cheese clot. The best results were achieved at the pasteurization temperature (86±2) °C and the coagulation temperature (32±2) °C.
The data obtained could make it possible to manage the process of making new types of cheeses with vegetable additives, depending on the specific conditions and requirements for the product

The coronavirus causing the Covid-19 pandemic has been experienced by us since 2020, which has led to an increase in the use of disposable medical masks in Indonesia and even worldwide. Polypropylene is a thermoplastic polymer used as the main ingredient in medical masks that takes more than 25 years to decompose in landfills. This research offers an innovative way to use medical mask waste in high-performance concrete. The resulting medical mask waste is subjected to a sterilization process and cut into fibers to analyze the effect of its addition on the compressive strength and splitting tensile strength of high-performance concrete. The research began with testing the physical and mechanical properties of the materials, designing a concrete mix using the absolute volume method, and taking samples for compression and splitting tests. The variation in the ratio of water-cement and pozzolanic materials w/(c+p) is 0.32. As a result, the compressive strength of concrete increased with a fiber size of 5×0.5 cm and 2×0.5 cm. An increase is up to 7 % with an optimum value of 72.37 MPa with a fiber size of 2×0.5 cm and a content of 0.15 %. However, there was a decrease in the compressive strength with a 5×1 cm mask fiber size. The overall split tensile strength value of all variations in waste fiber size and content increased with an optimum value of 7.29 MPa at 0.20 % fiber content with a fiber size of 5×0.5 cm. This indicates that polypropylene fibers from medical mask waste have a positive effect on high-performance concrete, namely improve the properties of concrete with a low tensile strength, which is expected to inhibit the propagation and reduce the size of cracks in reinforced concrete structures

The quality and comfort of clothing for people engaged in mountain tourism are influenced by the pack of clothing materials, which determine their durability and heat resistance. In practice, wear resistance and thermal insulation of clothing materials are evaluated by standard methods for single-layer materials. To solve the problem of studying the wear resistance and heat resistance of a clothing pack, we developed an experimental setup for studying the wear resistance of the clothing pack under the influence of cyclic loads and an installation for determining the heat-shielding properties of the pack of clothing materials, allowing you to reproduce both the temperature of the underwear space, as well as environmental factors.
By studying the influence of wind flow, humidity and ambient temperature on the heat-shielding ability of packages of various compositions, the most rational package of clothing for mountain tourism was determined. The selected package provides a comfortable state of a person in the absence of air permeability and at a wind speed of 5 m/s; and at wind speeds of 10 m/s and 15 m/s, the temperature of the underwear space decreases. The heat protection of the clothing package is influenced by the breathing of the athlete’s body during movements. So, at ambient temperature Tok=20 °C and humidity within 60‒70 % when the breathing simulator was turned on in the underwear space, Tpp=26 °C, W=62 %, and when it was turned off, Tpp=27 °C, and the humidity value did not change.
The developed experimental installations and research methods can be recommended for use at the design stage in the production laboratories of enterprises producing mountain sports clothing

In order for enterprises not to suffer significant losses by repurposing their activities for the manufacture of products attractive at certain points in time, it is necessary to take into account the compatibility of resource mutual support of the business processes they perform when forming the product range. Such compatibility and interaction should ensure the long-term efficiency of the enterprise and the strategic attractiveness of its products on the market.
Accordingly, the object of this study is the process that forms a rational resource base for effective long-term competitive development of the enterprise through the formation of an additional effect. Within the framework of the formed approach, the expediency to use the coefficient of managerial efficiency to choose the necessary source of resource provision (own production or alternative attraction of the necessary resources from an attractive stakeholder) has been proven.
The proposed recommendations should be applied to enterprises that use a significant number of parts, assemblies, and components for production; therefore, they have been tested on the activities of a machine-building enterprise. The results confirmed the feasibility of independent production by the studied enterprise of the relevant types of raw materials and the provision of certain services. This made it possible, by rationalizing the assortment policy of the enterprise, to create a closed production cycle and reduce, thereby, its dependence on third-party enterprises, which is extremely relevant under wartime conditions. In addition, the implemented measures made it possible to increase the volume of production of a particular type of product (vacuum pumps) by 10 %, reduce the reserve of production capacity, and ensure the stability of competitive advantages by increasing the service life and quality of individual components of the existing goods of the studied enterprise

This paper substantiates the expediency of conducting scientific research into the formation of the concept of tax benefits within the framework of technology transfer, which would meet the strategic interests of the state and business needs. The study is aimed at finding the optimal level of tax benefits within the existing means of state support for the introduction of new technologies.
It is proved that the effectiveness of preferential taxation depends on the area of implementation, the level of the economy, the sustainability and immutability of tax legislation. Normative means of formation of a system of preferential taxation of innovation activity and technology transfer within the legal system are proposed, namely:
1) a candidate for tax benefits from the state must undergo a special permitting procedure for confirming its legal status;
2) the system of tax benefits for participants in innovative relations and technology transfer should include two options for tax systems. On the one hand, there should be a system of tax benefits based on a preferential rate of income tax, value added tax, and an increased level of depreciation. On the other hand, a special type of simplified taxation system should be implemented, which should contain special (preferential) rates for paying a single tax;
3) the types of activities that can be carried out by business entities wishing to receive tax benefits should be limited by law. Such activities should include only those that carry out activities in the field of social production of goods.
The results of the study take into account the world experience of using similar means of support and can be used in the formation of regulatory means for regulating these relations

The problem that is solved in the research is to increase the efficiency of decision making in management tasks while ensuring the given reliability, regardless of the hierarchy of the system. The object of the research is the decision making support system in the field of democratic civilian control over the security and defense sector (FDCCSDS). The subject of research is the decision making process in management tasks using fuzzy cognitive maps and evolving artificial neural networks. The hypothesis of the research is to increase the number of sources of information about the components of the FDCCSDS, with restrictions on the efficiency and reliability of decision making. The research proposed a method for evaluating the information and analytical provision of public administration in FDCCSDS. It was established that the proposed method has a higher efficiency compared to the known ones by an average of 40 %, compared to the methods used to evaluate the effectiveness of strategic management decisions. The specified method will make it possible to assess the state of information and analytical provision of public administration in the FDCCSDS and to determine effective measures to improve efficiency. The method will allow to analyze possible options for the development of FDCCSDS in each phase of development and moments in time when it is necessary to carry out structural changes that ensure the transition to the next phase. At the same time, subjective factors of choice are taken into account while searching for solutions, which are formalized in the form of weighting coefficients for the components of the integral criterion of efficiency. The specified method allows to increase the speed of assessment of the state of information and analytical support of the FDCCSDS, to reduce the use of computing resources of and decision making support systems, to form measures aimed at increasing the efficiency of information and analytical support

The development of technologies and computing resources not only expanded the spectrum of digital services in all areas of human activity, but also defined the spectrum of targeted cyber attacks. The object of the study is the process of ensuring the safety of critical business processes that ensure the continuity of production and/or functioning of the company/organization/enterprise as a whole. Targeted attacks are aimed at destroying not only the business structure, but also its individual components that determine critical business processes. Continuity of such business processes is a critical component of any company, organization or enterprise of any form of government, which critically affects the earning of profits or the organization of production processes. The proposed concept of determining the security level of critical business processes is based on the need to use multi-loop information protection systems. This allows to ensure the continuity of critical business processes through a timely objective assessment of the level of security and the timely formation of preventive measures. This approach is based on the proposed rules for determining the achievement of a given level of security, which are based on assessments of the integrity, availability and confidentiality of information arrays, as well as computer equipment in relation to various points of the organization's business processes. The use of threat integration on the internal and external contours of the protection system allows to ensure the necessary level of security and continuity of the production/technological process of critical business processes. The proposed practical implementation of the system security level assessment system in the declarative programming language Prolog, which allows to form requirements regarding the achievement of a given system security level depending on the state assessments of individual system components
