Displacement: Trauma of Partition in Intizar Husain's Basti
Authors: Regmi Dipendra Raj
Published: May 2024

This paper examines the heartrending narrative of displacement in Intizar Husain's Basti (1979) through the concept of trauma of partition. Husain’s novel appears as a souvenir of the partition in front of readers. In the novel, Muslim narrator Zakir observes Pakistan's birth as a new nation in 1947. His migration to Pakistan from India after this political change represents the memory of the victims. Bangladesh emerged as a new nation in 1971 during his stay in Pakistan. These strange political upheavals create fear, disillusionment, and suspicion in the narrator’s mind. Therefore, this paper scrutinizes the reverberation of trauma in partition literature through Zakir’s narrative of displacement in Husain’s novel. As a qualitative applied research, the paper draws on ideas of trauma from Cathy Caruth and Jeffrey C. Alexander to analyze Zakir's story of displacement from India. Horrendous events and the period of their reverberation depend upon the intensity of the traumatic experience. The scene of Rupnagar represents Zakir’s memory of pre-partition but it triggers much when he experiences violence and war in Pakistan. The narrator’s dreadful experience survives in his diary, letters, and memoirs. By the way, this study aims to keep the memory of the victims alive to convey a message to the world. Partition is not only the division of geography, it is also the division of beautiful hearts. The division of a nation in the name of any banner obstructs political stability and the prosperity of humanity.
Living and Learning With Integrity: A Pushing and Pulling Ground for Teachers
Authors: Munakarmi Rupa
Published: May 2024

Teacher integrity is crucial for maintaining their own sense of ethical identity, professionalism, developing institutional culture of learning and sustainable development of schools. However, there are several elements related to socio-cultural norms, values and practices that support or resist the effective adoption of integrity at schools and in day to day life. This study explores how teachers’ professional integrity is shaped and practised at schools. Following the qualitative study design, I employed mostly literature review substantiated by in-depth interviews with six teachers from two schools in Kavre district. The findings reveal that school culture determines integrity of teachers. School environment, prescribed rights and duties of teachers and headteacher’s leadership shape the integrity of teachers. The social settings and its ingredients are pushing and pulling grounds that teachers address duly for effective implementation of integrity at schools. Since integrity is a social phenomenon deeply rooted in socio-cultural practices, the state needs to come up with more sensitive and inclusive code of conduct for responsive behaviours and better results that are contextually developed through the continuous participation of the concerned stakeholders of the schools.

Cellulose triacetate (CTA) nanofibers were formed by electrospinning using two binary solvent systems: methylene chloride/ethanol and chloroform/acetone. Previously, licorice root cellulose (LRC) with a degree of polymerization (DP) of 710 was extracted from licorice root waste by alkaline treatment and hydrogen peroxide bleaching at high temperatures. Then CTA with a degree of substitution (DS) of 2.9 and an average molecular weight of 175 kDa was synthesized from LRC using acetic acid and acetic anhydride, sulfuric acid was as a catalyst. The influence of the electrospinning process and various solvent systems on the morphology and structure of nanofibers is studied. The structure and morphology of the nanofibers were characterized by Fourier transform infrared (FTIR) spectroscopy, X-ray diffraction, scanning electron microscopy (SEM), thermal gravimetric analysis (TGA), and the sorption characteristics were also investigated. The results showed that the morphology and structure of nanofibers depended on the solvent mixture used. The average diameters of the CTA nanofibers with grooved morphology varied 200-700 nm (solvent methylene chloride/ethanol) and the dumbbell-shaped (flat ribbon) CTA nanofibers in a wide range from 200 nm to 4 mkm (solvent chloroform/acetone).
‘Ambrosio’ Taylor Coleridge: Investigating Three Issues in Banning The Monk
Authors: Lantz Derek
Published: May 2024

This paper investigates the banning in 1897 of Matthew Lewis's novel The Monk, taking special interest in the dismissal of the text by Samuel Taylor Coleridge. Sources reveal how British decency laws and the French Revolution together create a public repression which the Gothic novel both threatens and relieves in the 1890s. By highlighting journalistic reliance on Gothic terminology, the paper argues that banning art to protect citizenry is often a result of public insecurity rather than immoral content.
MOLECULAR GENETIC STATUS OF PIGS OF UKRAINIAN BREEDS SUITABLE FOR USE IN XENOTRANPLANTATION
Authors: Ryk T. M.
Published: May 2024

Thousands of people in Ukraine and the world need organ transplants. However, the main obstacle to the wider use of transplantation remains the shortage of donor organs and tissues. To prevent human infection with viruses during organ transplantation, pigs are carefully screened for PERV retroviruses and animals with low expression levels of PERV-A and PERV-C are selected.

The article is devoted to the discussion of the results of research on the frequency of retrovirus PERV types A and C in populations of Ukrainian pig breeds.

The research was carried out on samples of pigs of the following breeds: Mirgorod, Great White, Poltava meat, Ukrainian meat, Ukrainian Steppe Ryaba, Landras, Pietren, Vietnamese Vyslobryukha, Vietnamese Meishan, and wild pig. Biomaterial samples (venous blood, bristles with hair bulbs) were collected for molecular genetic analysis. Isolation of genomic DNA from the samples was carried out by the salt method and using the Chelex-100 ion exchange resin. Genotyping was performed by the method of allele-specific (PCR-SSP) multiplex polymerase chain reaction using primers complementary to regions of the PERV-C, PERV-A gene loci. A fragment of the domestic pig alpha-actin locus (α-Actin) was used as an internal PCR control. Amplification was carried out in a thermal cycler "Tertsik-2" ("DNA-technology", RF). Electrophoretic separation of amplified DNA sections in multiplex PCR format was performed in a 2% agarose gel in a tris-borate electrophoresis buffer.

It was established that among the studied groups of pigs, the highest concentration of retrovirus PEVR-C was found in animals of the breeds Vietnamese Vyslobrukha (100%), Poltava meat (75%), Ukrainian steppe spotted (55%), large white (50%), landrace (50%). The largest share of PEVR-A retrovirus carrier animals is characterized by the breeds of Vietnamese Vyslobrukha (100%), Poltava meat 95%), Pietren (80%) and Ukrainian meat (73%). The largest number of individuals free from PERV-A and PERV-C retroviruses were found in experimental groups of breeds of Ukrainian steppe spotted (75 and 45%, respectively), Myrhorod (32 and 75%, respectively), landrace (75 and 50%, respectively) and wild pig. Pigs these breeds can become promising organ donors for xenotransplantation.

Authors: Kostyna T. P. , Bronnikova L. F.
Published: May 2024

Soy is a strategic crop of global importance that plays a key role in overcoming the food crisis. In Ukraine, soybeans play an equally important role. Its beans have a unique combination of organic compounds and minerals of the two most important components - protein and oil - that play a key role in the physiological and biochemical processes of human and animal life. The formation of crop productivity occurs during the growing season in close connection with life factors.

The article highlights the peculiarities of soybean yield formation and investigates the impact of foliar nutrition on the main elements of the yield structure. The regularities of formation of individual productivity indicators, namely: the number of beans per plant, the number and weight of seeds per plant and the weight of 1000 seeds depending on the varietal characteristics of the crop and elements of its cultivation technology, are revealed.

Field studies have established a positive role of foliar feeding in the formation of high seed productivity of soybean varieties Triada and Avatar, and also revealed a link between the phase of foliar feeding and the level of yield.

Foliar application significantly influenced the chemical composition of soybean seeds, according to the data obtained from laboratory analyses. According to the chemical analysis, it was found that the formation of high indicators of the quality composition of soybean varieties was ensured by a combination of fertilisation in the budding and mid-flowering phases. The content of crude protein was 36.57-38.64 %, crude fat - 18.11-18.33 %, crude fibre - 10.44-10.70 %, crude ash - 5.23-5.25 %, BER - 27.30-29.43 %.

Published: May 2024

The relevance of the conducted research is determined by the lack of information in the available literature regarding the influence of iron and germanium nanoparticles on lipid exchange indicators in the plasma of sows. The aim of the study was to determine the effect of administering iron and germanium nanoparticles on lipid exchange indicators in the blood of sows before and after farrowing. The experiment was conducted on 24 large white sows, aged 2-3 years, which were divided into two groups (control and experimental). For ten days before farrowing, the sows in the experimental group were administered a complex of micronutrient compounds of iron – 3 mg/day and germanium – 0.01 mg/day. Blood plasma of the animals was used as material for the study, in which specific lipid exchange indicators were determined. The effect of farrowing on the content of triacylglycerols, non-esterified fatty acids, and total cholesterol in the blood plasma of animals was established (F= 33.0–156.0 > FU=2.9; P < 0.001). Before farrowing, there is a restructuring of lipid metabolism in sows, characterized by a decrease in the content of triacylglycerols and total cholesterol, and an increase in the content of non-esterified fatty acids in the blood plasma. It was found that within a day before farrowing, the content of triacylglycerols decreases by 30.6% (P≤0.001), total cholesterol by 18.3% (P≤0.01), and non-esterified fatty acids increase by 1.5 times (P≤0.001). Administering iron and germanium nanoparticles significantly affects the content of triacylglycerols (η²ᵪ=0.53; P≤0.05), total cholesterol (η²ᵪ=0.69; P≤0.01), and non-esterified fatty acids (η²ᵪ=0.50; P≤0.05) in the blood plasma of sows only on the day of farrowing. During this time, in the blood of sows administered metal nanoparticles, the content of triacylglycerols and total cholesterol is higher by 23.7% (P≤0.05) and 11.5% (P≤0.01), respectively, and the content of non-esterified fatty acids is lower by 9.2% (P≤0.05) compared to the indicators of animals in the control group. The prospects for further research lie in the development of modern methods to increase the productivity and resistance of sows using metal nanoparticles.

Published: May 2024

The article highlights the main aspects of the use of growth regulators in the cultivation of European larch seedlings by seed. In the research material of the article, laboratory studies were conducted to determine the effect of different concentrations of growth regulators on the formation of germination and germination energy of European larch seeds.

As a result of the research, it was found that the minimum concentration of agrostimulin also increased germination energy by 3.5 % and laboratory germination by 9.6 % compared to the control.

It was determined that the use of higher concentrations of agrostimulin concentrations (1 and 2 ml/l) led to an increase in germination energy by 7.8 % and 11.5 %, respectively, and to an increase in germination rate by 14.7 % and 20 %.

It was found that the concentration of 2.0 ml/l of emistim-C was the most effective, increasing germination energy by 12.1% compared to the control variant, and laboratory germination reached its maximum value at a concentration of 2 ml/l and exceeded the control by 15.9%.

The study revealed that an increase in the concentration of PABA solutions contributes to an increase in germination energy and laboratory germination of European larch seeds. The most pronounced effect is observed at a concentration of 100 mg/l and is 59.6 % and 72.8 %, respectively.

The results of the study show that solutions of Triman-1 in concentrations of 25 mg/l and 50 mg/l have a positive effect on germination energy, increasing it by 9% and 9.9% and laboratory germination of European larch seeds by 12.3% and 13.9%, respectively.

Also in the course of the research, it was determined that excessive concentrations of different types of growth regulators gave insignificant results compared to the control, which indicates the ineffectiveness of their use.

Authors: Maguran V. K. , Osadchuk L. S.
Published: May 2024

The comparative analysis of seed germination and growth of walnut and black walnut seedlings in the conditions of the Right-Bank Forest-Steppe of Ukraine was carried out. It was found that in rows with a sowing depth of 10 cm and 13 cm, the germination rate of walnut had the highest rates and amounted to 70% and 63%, respectively, and black walnut - 80% and 84%. The lowest germination rate was observed at a sowing depth of 17 cm for walnut and 6 cm for black walnut, 46% and 39%, respectively. The influence of the position of the walnut seeds on their germination was determined. In particular, when sown by the "top up" and "on the edge" methods, the germination rate was 70% and 72%, which is 24-26% higher than the "top down" and "side by side" methods. The germination energy of black walnut seedlings was found to be higher than that of walnut seedlings. The first signs of germination of black walnut were observed 7 days earlier than in field crops of walnut. It was found that the main growth of seedlings in height began from the end of the first decade of June and lasted until the first decade of August. The average height of black walnut seedlings was 50 cm, while the average height of walnut seedlings was 19 cm lower and amounted to 31 cm. The yield of standard black walnut seedlings was recorded at 69% of the total number of seedlings, while in walnut this figure was only 12%. The compatibility of the varieties 'Webu-6', 'Chandler' and 'Kazaku' with black walnut and walnut during the cultivation of grafted seedlings was studied. It was found that the selected experimental varieties of walnut, which were grafted onto black walnut seedlings, showed approximately the same formation of callus tissues, except for the variety 'Vebu-6'. This once again confirms the information that not all walnut varieties can participate in interspecific combinations. It was found that the length of the central root of the black walnut at the end of the first year of cultivation is 15 cm longer than the length of the central root of the walnut and averages 43 cm. The main branching of lateral roots in walnut occurs at a depth of 10 to 20 cm. The number of main skeletal roots is generally 3-4 units. At the end of the first year of cultivation, the seedlings had a significantly smaller root system compared to black walnut. The root system of standard black walnut seedlings is on average 60% larger than that of walnut. The main branching of lateral roots is on average at a root length of 7 to 30 cm. Similar to the walnut, the root system of black walnut has 2-3 tiers. The number of skeletal roots averages 8-10 pieces, and the length of the main skeletal roots ranges from 15 to 30 cm. According to the research results, it can be concluded that walnut seedlings grafted on black walnut seedlings have prospects for further introduction into production as they can bear fruit faster, have relatively restrained growth, allow for the formation of a crown at the 3rd year of life and have a more powerful root system.
DECOMPOSITION OF FAILURE STATES OF GRAIN HARVESTING COMBINERS
Authors: Rogovskii I. L. , Nichay I. M.
Published: May 2024

The article discloses methodological approaches to the formation of the validity of the application of the simulation model of the decomposition of failure-free states of combine harvesters. The authors reproduce the functional decomposition of the reliability of grain harvesters obtained through the analysis of system functions. The authors reveal analytical approaches to the question of what the system does, regardless of how it works. As a basis, the authors formed a division into functional subsystems in the community of functions performed by groups of elements. When conducting the experiment, a set of random events that occur with the module under consideration is first generated - the event of failure of the blocked module, the event of activation of the blocking of the module and the event of the transmission of the module. Then, by assigning the corresponding probabilities, states are defined and logical dependencies between them are found. The experiment consisted in the sequential generation of events and obtaining the final states of the functional module. This experiment was repeated several times, then it was calculated, in several cases the functional module of the grain harvester was in good condition. The ratio of the number of experiment results in which the functional module was found to be working to all results shows the possibility of the functioning of the functional module. By performing a certain number of calculations of each state, summing the results of each calculation, taking the true value as one and the false value as zero, and then dividing the result by the length of the set, we obtain the value of the probability of blocked failure calculated by the Monte Carlo method.When performing the calculations and with the original data, it was equal to 0.885. The similarity of the result to the result accepted as true proves the truth. The method given in the article allows to improve the quality of work of the fail-safe system of grain harvesters, providing more accurate failure-free accounting, expanding the list of analyzed reliability parameters and making fuller use of technical means of monitoring technical condition parameters.
Methodological approaches to economic and mathematical modelling of crop rotation in the development of a land management project that provides ecological and economic justification for crop rotation
Authors: Dorosh Y. , Ibatullin Sh. , Dorosh O. , Dorosh А. , Sakal O.
Published: May 2024

The proposed research paper systemises methodological approaches to optimisation and dynamic modelling of crop rotation in the development of land management projects that provide ecological and economic justification of crop rotation, since the crop rotation models proposed to date do not solve the task in general, but only in certain specific cases. In this regard, the need to develop full-fledged software products with a user interface integrated into existing information and accounting databases of agricultural formations is substantiated.
It is proved that economic and mathematical modelling of crop rotations should be developed by improving the methodology of dynamic crop rotations, which will allow farmers to analyse the economic efficiency of various alternative options for crop rotation under specific natural and economic conditions and constraints, as it is a promising interactive tool for substantiating management production decisions based on optimisation algorithms and analysis of large amounts of accumulated retrospective data.
The approaches, criteria and limitations of the economic and mathematical model of crop rotation in the development of land management projects that provide ecological and economic justification of crop rotation are substantiated.
The proposed economic and mathematical model with its objective function, constraints and algorithms is aimed at a comprehensive solution of issues related to production planning and rational land use. The presented model provides ample opportunities for further optimisation of the system of making effective managerial decisions in the agricultural sector and can serve as a basis for solving the problems of investment justification and development of agricultural land use.

Authors: Abu-Rabia Aref
Published: May 2024

Modern medicine has penetrated Bedouin tribes in the course of rapid urbanization and education, but when serious illnesses strike, particularly in the case of incurable diseases, even educated people turn to traditional medicine for a remedy. Over the course of 30 years, the author gathered data on traditional Bedouin medicine among pastoral-nomadic, semi-nomadic, and settled tribes. Based on interviews with healers, clients, and other active participants in treatments, this book will contribute to renewed thinking about a synthesis between traditional and modern medicine — to their reciprocal enrichment.
FINAL SALE IN BERLIN
Authors: Kreutzmüller Christoph
Published: May 2024

Before the Nazis took power, Jewish businesspeople in Berlin thrived alongside their non-Jewish neighbors. But Nazi racism changed that, gradually destroying Jewish businesses before murdering the Jews themselves. Reconstructing the fate of more than 8,000 companies, this book offers the first comprehensive analysis of Jewish economic activity and its obliteration. Rather than just examining the steps taken by the persecutors, it also tells the stories of Jewish strategies in countering the effects of persecution. In doing so, this book exposes a fascinating paradox where Berlin, serving as the administrative heart of the Third Reich, was also the site of a dense network for Jewish self-help and assertion.
RECOVERED TERRITORY
Authors: Polak-Springer Peter
Published: May 2024

Upper Silesia, one of Central Europe’s most important industrial borderlands, was at the center of heated conflict between Germany and Poland and experienced annexations and border re-drawings in 1922, 1939, and 1945. This transnational history examines these episodes of territorial re-nationalization and their cumulative impacts on the region and nations involved, as well as their use by the Nazi and postwar communist regimes to legitimate violent ethnic cleansing. In their interaction with—and mutual influence on—one another, political and cultural actors from both nations developed a transnational culture of territorial rivalry. Architecture, spaces of memory, films, museums, folklore, language policy, mass rallies, and archeological digs were some of the means they used to give the borderland a “German”/“Polish” face. Representative of the wider politics of twentieth-century Europe, the situation in Upper Silesia played a critical role in the making of history’s most violent and uprooting eras, 1939–1950.

Structure of Spread Spectrum Telemetry Radio Link for LEO Small Satellite
Authors: Karavaev D. , Glushankov E.
Published: May 2024

The paper considers the design of telemetry radio link for low Earth orbit (LEO) satellites, particularly based on CubeSat format. A significant limitation of such spacecrafts are the available dimensions for antennas and the transmitting power, which leads to low energy level at the ground receiving point of transmitted signal. The article presents the physical level structure for data frame based on direct sequence spread spectrum technique, which allows for additional signal gain to achieve the required level of link performance. Using such principle also make possible to implement adaptive data rate control depending on dynamics in signal-to-noise ratio when the distance from the satellite to the ground point changes. For proposed data frame structure, an analysis of received information size during a communication session was carried out, which is parameterized on the maximum observable elevation angle of the satellite. The issue of datalink layer interaction between devices is also considered.
A Research of Intermodulation Components in Laser Vibrometers for Precise Measurement of Oscillations
Authors: Kravets Е. , Semenova E.
Published: May 2024

This paper presents the results of theoretical research of signals of laser vibrometers, with the surface of the object of interest orthogonal to the direction of the beam. The article shows that the Michelson interferometer based vibrometer may yield erroneous results when measuring the amplitude of oscillations. The errors arise due to the phase shift between the interfering beams, which affects the measurement of the absolute value of surface shift. The article presents theoretical analysis of the spectra of the output signals of interferometers of various designs. For the Michelson interferometer based vibrometer, the algorithm for the measurement of frequencies and amplitudes by reading the oscillograms of interference signals suggests that the amplitude be much larger than the laser's wavelength. It is proved that in this case the result does not depend on the mismatch in phases between the beamsplitter and each mirror. The output signal of the heterodyne interferometer has been analyzed. The property of spectral components of being independent of the beams' phases helps eliminate errors when calculating the amplitude. A special design of the Michelson interferometer is proposed, where the beam's frequency is shifted by using the optical modulator that operates in the Bragg diffraction mode.

Authors: Nguyen Manh Hung , Van Nguyen Hong , Tran Van Quan
Published: May 2024

Forecasting container ship arrival times is challenging, requiring a thorough analysis for accuracy. This study investigates the effectiveness of machine learning (ML) techniques in maritime transportation. Using a dataset of 581 samples with 8 input variables and 1 output variable (arrival time), ML models are constructed. The Pearson correlation matrix reduces input variables to 7 key factors: freight forwarder, dispatch location, loading and discharge ports, post-discharge location, dispatch day of the week, and dispatch week. The ranking of ML performance for predicting the arrival time of container ships can be arranged in descending order as GB-PSO > XGB > RF > RF-PSO > GB > KNN > SVR. The best ML model, GB-PSO, demonstrates high accuracy in predicting the arrival time of container ships, with R2 = 0.7054, RMSE = 7.4081 days, MAE = 5.1891 days, and MAPE = 0.0993% for the testing dataset. This is a promising research outcome as it seems to be the first time that an approach involving the use of minimal and easily collectible input factors (such as freight forwarder, dispatch time and place, port of loading, post port of discharge, port of discharge) and the combination of a machine learning model has been introduced for predicting the arrival time of container ships.

Authors: Parthiban P. , Vaisakhi V.S.
Published: May 2024

Wireless sensor network (WSN) collect and detect data in real time, but their battery life limits their lifetime. The CH selection process increases network overhead and reduces lifetime, but it considers node processing and energy limitations. To solve that problem this research methodology proposed Multi Objective Energy trust - Aware Optimal Clustering and Secure Routing (MOETAOCSR) protocol. At first, the trust factors such as direct and indirect factors are calculated. Thus, the calculated values are given as input to the SDLSTM to detect the malicious node and normal node. Here, the network deployment process is initially carried out and then the cluster is formed by HWF-FCM. From the clustered sensor nodes, the cluster head is selected using Golden Jackal Siberian Tiger Optimization (GJSTO) approach. Then, the selection of CH the paths are learned by using the Beta Distribution and Scaled Activation Function based Deep Elman Neural Network (BDSAF-DENN) and from the detected paths the optimal paths are selected using the White Shark Optimization (WSO). From the derived path sensed data securely transferred to the BS for further monitoring process using FPCCRSA. The proposed technique is implemented in a MATLAB platform, where its efficiency is assessed using key performance metrics including network lifetime, packet delivery ratio, and delay. Compared to existing models such as EAOCSR, RSA, and Homographic methods, the proposed technique achieves superior results. Specifically, it demonstrates a 0.95 improvement in throughput, 0.8 enhancement in encryption time, and a network lifetime of 7.4.

Published: May 2024

The q-rung orthopair fuzzy set (q-ROFS) is a moderate mathematical model, that has diverse capabilities to handle uncertain and ambiguous information of human opinion during the decision analysis process. The Aczel Alsina operations are more flexible and valuable aggregating tools with parameter values ϻ ⩾ 1, reflecting smooth and accurate information by aggregating awkward and redundant information. The theory of the Choquet integral operator is also used to express the interaction between preferences or criteria by incorporating certain values of preferences. The primary features of this article are to derive some dominant mathematical approaches by combining two different theories like Choquet integral operators and operations of Aczel Alsina tools namely “q-rung orthopair fuzzy Choquet integral Aczel Alsina average” (q-ROFCIAAA), and “q-rung orthopair fuzzy Choquet integral Aczel Alsina geometric” (q-ROFCIAAG) operators. Some special cases and notable characteristics are also demonstrated to show the feasibility of derived approaches. Based on our derived aggregation approaches, a multi-attribute decision-making (MADM) technique aggregates redundant and unpredictable information. In light of developed approaches, a numerical example study to evaluate suitable safety equipment in the construction sector. To reveal the intensity and applicability of derived approaches by contrasting the results of prevailing approaches with currently developed AOs.

BACKGROUND: In recent years, Despite the proven economic growth brought by AI technology globally, the adoption of AI in the construction industry faces obstacles. To better promote the adoption of AI technology in the construction domain, this study, based on the extended Unified Theory of Acceptance and Use of Technology (UTAUT) model, delves into the key factors influencing the adoption of AI technology in the construction industry. By introducing personal-level influencing factors such as AI anxiety and personal innovativeness, the UTAUT model is extended to comprehensively understand users’ attitudes and adoption behaviors towards AI technology. METHODOLOGY: The research framework is based on the Unified Theory of Acceptance and Use of Technology (UTAUT) with the added constructs of artificial intelligence anxiety and individual Innovativeness. These data were collected through a combination of online and offline surveys, with a total of 258 valid data collected and analyzed using structural equation modeling. RESULTS: The study found that Usage Behavior (UB) in adopting Artificial Intelligence (AI) is positively influenced by several factors. Specifically, Performance Expectancy (PE) (β= 0.266, 95%), Effort Expectancy (EE) (β= 0.262, 95%), and Social Influence (SI) (β= 0.131, 95%) were identified as significant predictors of UB. Additionally, Facilitating Conditions (FC) (β= 0.168, 95%) also positively influenced UB.Moreover, the study explored the moderating effects of Artificial Intelligence Anxiety and Individual Innovativeness on the relationships between Performance Expectancy (PE), Effort Expectancy (EE), Social Influence (SI), and Facilitating Conditions (FC) with the Usage Behavior of AI technology. PRACTICAL IMPLICATIONS: This study lie in informing industry stakeholders about the multifaceted dynamics influencing AI adoption. Armed with this knowledge, organizations can make informed decisions, implement effective interventions, and navigate the challenges associated with integrating AI technology into the construction sector.

Published: May 2024

COVID-19 and military operations have significantly changed the security situation for Ukrainian enterprises. The existing security systems were not ready for the existing critically high and difficult to predict dynamics of influence of previously secondary factors. The weak link turned out to be subsystems of information and analytical support, which were mostly focused on assessing the economic security of the enterprise based on reporting data. The current attempts of trade enterprises to adapt to the conditions of operation during the martial law actualized the problem of improving the information base of security activities. The purpose of the study is to develop a technology for evaluating the effectiveness of security activities of a trading enterprise. To develop a technology for evaluating the effectiveness of the security activities of a trading company, the following methods were used: induction and deduction, comparison and systematization – during the study of the existing practice of evaluating the security activities of enterprises; synthesis and analysis – for the calculation of primary indices, group and integral indicators; morphological analysis – to determine the list of primary indexes; expert survey – to establish weighting factors; graphic – for visual representation of theoretical and methodical material; abstract-logical – for theoretical generalizations and research conclusions. On the basis of a careful study of existing developments, a variant of the technology for evaluating the effectiveness of security activities of trade enterprises is proposed. The developed technology is a combination of knowledge (including methods, tools, techniques, principles), experience, organizational, technical and other decisions about the conditions, principles and sequence of operations, the implementation of which allows you to get a holistic vision of the course of security processes and the activity of sub security entities in the performance of specified tasks. The three components involve the calculation of a wide list of primary indicators, followed by their unification into group indicators and the determination of an integral indicator, which is facilitated by weighting factors that maximally take into account the specifics of trade and ensuring security in the conditions of the relevant economic entity. The use of the developed technology made it possible to obtain information about the actual results of the security activities of individual trade enterprises during 2021–2023, in particular in terms of countermeasures and elimination of threats related to COVID-19 and military actions.
