PRINCIPLES AND FACTORS OF FORMING CORPORATE SOCIAL RESPONSIBILITY IN CONSTRUCTION
Authors: Bielienkova O. , Loktionova Ya.
Published: February 2025

Abstract. The article examines a number of theoretical approaches to the concept of "corporate social responsibility (CSR)" in the context of construction. It is found that corporate social responsibility is an element of the activities of modern construction companies, which then have a significant impact on the environment, economy and society. The article examines the main principles and factors that initiate the process of forming CSR in the construction sector.
The key principles of implementing corporate social responsibility in construction include a responsible attitude to the environment, social support for employees, compliance with ethical standards of business conduct, transparency of activities and interaction with stakeholders. The implementation of these principles allows construction companies to build consumer trust, attract investors and increase their competitiveness in the market.
One of the key factors influencing the formation of CSR in construction is environmental responsibility. The use of energy-efficient technologies, reduction of emissions of harmful substances and disposal of construction waste contribute to reducing the negative impact of the construction industry on the environment. Another aspect is ensuring decent working conditions, which includes compliance with safety standards, social guarantees for employees and the development of their professional skills.
In addition, the company's social responsibility is manifested in supporting local communities, implementing charitable projects, building social infrastructure and participating in sustainable development initiatives. Economic responsibility is responsibility for the transparency of financial activities, compliance with legislation, combating corruption and openness in relations with partners.
Thus, corporate social responsibility in construction is a comprehensive system of measures that contributes to the sustainable development of the industry. Its implementation allows companies not only to minimize risks, but also to strengthen public trust, form a positive image and ensure long-term economic stability. It has been determined that corporate social responsibility plays a key role in shaping consumers' economic trust in construction companies.

Published: February 2025

Abstract. The article examines the experience of forming bankruptcy prevention strategies, forming a system of economic security of construction enterprises, and anti-crisis management. Various methods and approaches to the formation of a system of indicators for assessing the threat of a financial crisis of the enterprise have been studied, as well as providing practical recommendations for improving the monitoring of threats to the economic security of the construction business. In the absence of a unified approach, it is proposed to take the factors of the "crisis field" as an approximate list, which in the process of assessing the degree of economic security of construction enterprises are recommended to be supplemented or reduced, based on the specifics of the enterprise's activities and reporting. Indicators of diagnostics of economic security of the enterprise are proposed to be divided into direct and indirect (mediated) according to the degree of influence. The research of many authors who believe that the indicators and risks of one and the same enterprise are different depending on the stage of its life cycle is analyzed. Some authors suggest measuring the life cycle of an enterprise by cash flow, others suggest determining the stage of the life cycle based on data on the enterprise's revenue. The matrix of diagnostic indicators and the dynamics of their level by stages of the life cycle of the enterprise is considered. The critical risks of the enterprise are analyzed depending on the stage of its life cycle. Some authors suggest measuring the life cycle of an enterprise by cash flow, others suggest determining the stage of the life cycle based on data on the enterprise's revenue. The matrix of diagnostic indicators and the dynamics of their level by stages of the life cycle of the enterprise is considered. The critical risks of the enterprise are analyzed depending on the stage of its life cycle. The main approaches to assessing the company's potential have been studied. Theoretical and methodological approaches to assessing the anti-crisis potential of the enterprise and ensuring the economic security of the enterprise were considered, factors affecting the economic security of construction enterprises of Ukraine were investigated, and possible methods of its assessment and forecasting were analyzed. Complexes of primary financial indicators prioritized for the implementation of anti-crisis diagnostics are substantiated, on the basis of which the conditions of effectiveness of anti-crisis management are determined. Indicators have been identified that objectively reflect the anti-crisis potential of the construction enterprise and comprehensively characterize its financial, production and investment activities.
READJUSTMENT OF THE CONTENT OF DEVELOPMENT PROJECT PREPARATION FOR SUCCESSFUL IMPLEMENTATION IN THE CONDITIONS OF DIGITAL SOCIETY AND DIGITAL ECONOMY
Authors: Malykhin M.O.
Published: February 2025

Abstract. In the conditions of rapid digitalization of society and economy, development projects require significant adaptation for successful implementation. Reconfiguration of the content of preparation of such projects is a necessary condition for their competitiveness and efficiency in the digital environment. Modern technologies such as artificial intelligence, big data, blockchain, the Internet of Things and process automation play a key role in transforming approaches to development, increasing the accuracy of forecasts, reducing risks and optimizing costs. The first aspect of the reconfiguration is the integration of digital technologies at all stages of project preparation and implementation. This includes the use of innovative software platforms for project management, which allow coordinating all aspects of development from conceptual design to construction and operation of facilities. Such platforms help improve communication between teams involved in the project and ensure transparency in decisionmaking. As a result, the process becomes more flexible and operational. The second important factor is data analytics. The large amounts of information that can be collected and analyzed using digital tools allow developers to more accurately predict market trends, assess potential risks and develop the most effective strategies for project development. Digital models and simulations help to better assess possible project implementation scenarios, taking into account various external factors, such as changes in the economy or regulation. Equally important is the adaptation of organizational processes in development. The transition to a digital economy requires new approaches to organizing work, which involves reengineering business processes. In particular, it is necessary to optimize the interaction between departments, automate routine operations, and implement tools for remote project management. This ensures increased productivity and more efficient use of resources. It is also important to note the importance of developing new competencies for development specialists. Successful digital transformation is impossible without improving the skills of personnel and implementing new approaches to training. It is important to develop a digital culture in organizations, train specialists to work with the latest tools and technologies, and create an environment that will promote innovation and flexibility. That is why development companies should not only adapt technological tools, but also ensure the professional development of their employees.

Authors: Tsyfra T. , Hryhanska K. , Hut Ya.
Published: February 2025

Abstract. The influence of business reputation on the efficiency of development of the State Research Institute of Building Constructions is investigated. The economic essence of the concept “goodwill” as an intangible asset is established. The model of goodwill valuation for the construction scientific institute on the example of the State Research Institute of Building Structures is developed. To date, the assessment of business reputation has become more and more interested in enterprises due to the instability of markets. Formation of positive goodwill becomes extremely important, because positive goodwill can distinguish the enterprise among others engaged in similar activities, expand the circle of consumers, strengthen the position in the market.
Thus, in the course of the study, the main components of the business reputation of the SE NDIBK in the pre-war period were identified and the calculation of goodwill for the construction design institute was proposed using the factor method.
The main components of the goodwill of SE NDIBK are grouped according to the following factor indicators: history (number of years on the construction and design market, rhythmic performance of scientific research and scientific design works); personnel (staff professionalism, level of education, knowledge, skills staff experience); means (material and technical base financial autonomy unfinished works); image (citation, case law of the organization, feedback from customers, information on international scientific cooperation).
It was determined that the value of goodwill of SE NDIBK as of 01.01.2022 of the pre-war period is 66.06, which is a fairly good result, given that the best value that can be obtained by the value of goodwill using this method is 100.
To summarize, goodwill plays a significant role as a key performance indicator (KPI) in the business world. It helps stakeholders understand the value of intangible assets, such as reputation and customer relationships, that contribute to a company's success. By considering goodwill as a KPI, companies can better assess their competitive advantage and make more informed decisions about mergers and acquisitions.
Andriy Petrovskyi Еarly Years Artistic Approach: from the Glassblower to Professional Artist
Authors: Yakymova Olena
Published: February 2025

Andriy Petrovski is widely recognized in Ukraine’s artistic community, particularly in Lviv, as well as abroad as a glass artist. In 2024, he was awarded the Regional Prize of Lviv oblast (region) named after Zenoviy Flynta in the field of culture, literature, art, journalism, and architecture for his series of creative works titled “Thoughts about…”. The series was created between 2021 and 2024 and is likely to continue.
Andriy Petrovski's art pieces are in high demand on the international market, being sold on global online platforms such as Artsy and Wright, as well as featured in various auctions. However, his path toward becoming a professional artist remains relatively unknown. His formal and informal mentors in the glassblowing and, subsequently, glass art were glassmakers from the Lviv Ceramics and Sculpture Factory (LKSF) and a generation of glass artists who were the pioneers of the studio glass movement in Ukraine, exactly in Lviv, particularly A. Bokotey and F. Chernyak.
Based on interviews with the artist himself, this study reveals the phenomenon of his creative method, which began to take shape during his time as a master glassblower at the Lviv Ceramic and Sculpture Experimental Factory and continues to evolve today. Using photos provided by the artist and the data gathered during interviews, the article describes the visual and artistic-plastic characteristics of his glass works. It also analyzes the artistic and conceptual aspects of his creations, starting with his earliest experiments in serial production at the LKSF, followed by his exploration of form and artistic language during his studies at the Lviv Academy of Arts to his first independent works.
One of the defining characteristics of Petrovski’s glass pieces has been the use of colorless glass and experiments with materials that could give it color and texture. At the same time, he explored form itself and its possibilities, particularly its scale, in creating large-scale glass sculptures – an important professional challenge for the young artist.

Aim: To identify peptides derived from bovine lactoferricin (LfcinB) as potential therapeutics for colon cancer treatment. We systematically modified dimeric peptides to enhance their selectivity against colon cancer cells and reduce toxicity. We examined the effects of specific changes, such as substituting L-arginine (Arg) with L-ornithine (Orn) and/or D-Arg, on cytotoxic activity in colon cancer cells, as well as activity in prostate and cervical cancer cell lines. Additionally, we assessed the type of cell death induced and the in vivo toxicity of the dimeric peptides. Methods: The peptides were synthesized by manual solid-phase peptide synthesis, purified by reverse phase-solid phase extraction (RP-SPE), and characterized by RP-high performance liquid chromatography (RP-HPLC), and mass spectrometry (MS). Their cytotoxic effect on cancer and non-cancerous cells was evaluated by 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) assay. The most promising dimeric peptide underwent scale-up synthesis to yield approximately 1 g. The type of induced cell death was analyzed through cytometry assays, while preliminarily toxicity studies were conducted in Galleria mellonella, zebrafish, and CD1 mice. Results: Our findings demonstrated that dimeric peptides containing L-Orn or D-Arg residues exhibited potent and selective cytotoxic effects against colon cancer cells (Caco-2 and HT-29), prostate cancer cells (DU-145), and cervical adenocarcinoma (HeLa). Notably, these modified peptides showed minimal toxicity in human erythrocytes, HEK 293 cells or fibroblasts, and Galleria mellonella larvae. Peptide 3: (R-Orn-WQWRFKKLG)2-K-Ahx, emerged as particularly promising, preserving its integrity and anticancer activity during scaled-up synthesis. Furthermore, peptide 3 induced behavioral changes and sedation in CD1 mice and showed significantly lower toxicity in zebrafish. Conclusions: The results suggested that specific modifications of Arg/Orn residues in dimeric peptides enhance their cytotoxicity against colon cancer cells and reduce in vivo toxicity. These modified peptides hold promise as safe and effective therapeutic candidates, potentially expanding the treatment options available for cancer.

Authors: Zhao Yue , Zhang Zhan , Qiu Jian-Hao , Li Rong-Yang , Sun Zhen-Guo
Published: February 2025

In recent years, significant progress has been made in the application of DNA methylation for the early detection of esophageal cancer (EC). As an epigenetic modification, DNA methylation allows for noninvasive screening by detecting the methylation status of circulating tumor DNA. Studies have shown that the methylation of genes such as SHOX2 , SEPTIN9 , EPO , and RNF180 significantly improves diagnostic sensitivity and specificity. Currently, SEPTIN9 has been approved by the Food and Drug Administration for colorectal cancer screening, while SHOX2 and EPO show promising results in EC, and RNF180 has potential in gastrointestinal tumors. This editorial reviews the study by Liu et al , which demonstrated the potential of combining the methylation of these four genes for early EC screening. In addition to their roles in early diagnosis, DNA methylation markers are gaining attention because of their roles in predicting recurrence and in postoperative follow-up. By monitoring changes in methylation levels, these markers can provide valuable insights into treatment efficacy and long-term management. As research progresses, liquid biopsy technology is expected to become an essential tool in the precision diagnosis and treatment of EC, benefiting patients significantly.

The interaction of study sequence presentation mode and response assignment reveals the effects of multiple computational systems on an immediate visual recognition task
Authors: Glass Arnold L. , Wang Tingtao , Fu Allyson
Published: February 2025

Participants responded whether a single digit was in the immediately preceding digit sequence by pressing one of two keys as rapidly as possible while trying to avoid errors. Each participant performed four different kinds of sessions: Either all of the digits of the study sequence were presented in the same position or the digits were presented in successive positions from left to right. Either the same response was assigned to the right key and the different response to the left key or vice versa. Response time (RT) was an increasing function of the length of the study sequence. RT was an increasing function of the target’s position in the study sequence when the different response was assigned to the right key. When the same response was assigned to the right key, RT was a decreasing function of the target’s position in the study sequence when the study sequence had been presented in one location but there was no effect of target position on RT when the study sequence had been presented from left to right. The effects of study sequence length and target position were independent in the three conditions in which there was an effect of target position. Also, RT decreased for targets that had previously appeared as test items but RT increased for lures that had previously appeared as test items. The results confirm a dual-system hypothesis of recognition involving both the perceived recency of the target and the retrieval of the previous context of the target.

Published: February 2025

Nowadays, energy demand continuously rises while energy stocks are dwindling. Discovering new energy resources in addition to using current resources more effectively are crucial for the world this century. One of the methods to utilize energy resources effectively is to generate electricity from thermal combined cycle power plants (CCPP). Conducting performance analysis is a necessity to achieve effective operating conditions of thermal plants. The current paper offers a theoretical analysis of exergy losses of a typical CCPP over at various temperature and relative humidity ranges. Exergy destruction and the exergy efficiencies of each component of a thermal plant are calculated as well as subjecting them to parametric analysis. Energy and exergy efficiencies of the CCPP in the current study were 48.19% and 46.49%, respectively. Exergy destruction of a CCPP decreases with increasing ambient temperature and relative humidity. Exergy efficiency of a CCPP drops with increased ambient temperature. It is found that the combustion chamber is responsible for most of the exergy destruction amongst the system components.

PVsyst is a simulation software that is widely used by researchers and industry professionals for PV system design, performance simulation, technical analysis, and economic assessment. However, a study to verify the accuracy and reliability of PVsyst is necessary to ensure the simulation results align with industry standard with minor inconsistencies in the prediction of energy production. This paper presents a comparison of the design, simulation, and performance analysis of a grid-connected solar system in Johor Bahru. Three methods were applied in this study, which are two Mathematical Models (MM)s and PVsyst commercial software. A comparison of PVsyst simulation with existing mathematical models was conducted to identify discrepancies in the prediction of energy production between the methods. The comparison involved assessing the annual and monthly energy generation predicted by MMs and PVsyst. Results shows that the percentage difference between PVsyst and MM 1, as well as PVsyst and MM 2, are respectively 14.63% and 5.803%. This study also highlighted several technical understandings of designing PV systems by using the three methods which can help in understanding the differences in the predicted energy generation.

Logistics operations play a crucial role in the overall business activities, especially in today’s global and interconnected marketplace. A well-implemented logistics operation leads to cost savings and enhanced market responsiveness, resulting in an overall business competitiveness in today’s challenging business environment. This study used Principal Component Analysis (PCA) and Data Envelopment Analysis (DEA) to analyze the performance of 14 well-known logistics companies in Malaysia from the year 2010 until 2020. The most crucial factor affecting logistics performance was identified using PCA to reduce data dimensionality. PCA results showed that current assets, net fixed assets, current liabilities, operating income, and revenue significantly affected the performance of logistics companies. Then, the efficiency frontier was evaluated using DEA, which considered current assets, net fixed assets and current liabilities as input while operating income and revenue as output variables. In the DEA process, Lingkaran Trans Kota Holdings Berhad is the only company that maintained a full efficiency score of 100 percent throughout the entire period, indicating the efficient utilization of its resources. On the other hand, MISC Berhad was the least efficient, with an average efficiency score of 32.17 percent. This study’s findings can be used to increase organizational competitiveness by optimizing performance and boosting efficiency.

Published: February 2025

Economic use of resources and technologies is mainly achieved using optimization frameworks. Optimizations for renewable energy system planning and operations are mainly implemented using either or combination of classical, intelligent-based, or off-the-shelf software techniques (tools). Each of the homogenous technique implementations exhibits a form or more of its opportunities and limitations. Classical techniques are opaque and loaded with computational burdens, however, they tend to be fast in achieving global solutions without branching at local solutions. The intelligent-based techniques such as metaheuristics are simple and transparent, however, the results they produce are not always optimal, even though acceptable. The software tools are inflexible for customized applications, but the results they produce are always optimal and fast implementations. This paper considers the constraints of Nigerian semiarid weather data, renewable energy components and residential demands to configure a nanogrid using Nested Integer Linear Programming, Particle Swarm Optimization and Hybrid Optimization of Multiple Energy Resources optimization software as samples of the foregoing classification of optimization tools. The objective is to compare the performance of each of the tools’ homogeneity, to derive their benefits and drawbacks. Results show that Hybrid Optimization of Multiple Energy Resources has the highest configurational capacity of 46.5 kW with the lowest Levelized Cost of Energy of 0.2220 $/kWh. The Nested Integer Linear Programming having the lowest capacity of 21.26 kW derived 0.3375 $/kWh as Levelized Cost of Energy, while Particle Swarm Optimization with an average capacity of 27.05 kW obtained the Levelized Cost of Energy of 0.4777 $/kWh. This implies that higher investment derives lower energy costs. Hence, future use of the techniques’ homogeneity or otherwise may be subject to achieving balances between the benefits and drawbacks exhibited by the techniques and underlying renewable energy-based objectives.

Published: February 2025

The turbulent flow in a separated region is still a fundamental area of research due to the advent of space shuttles and high-performance military aircraft, and turbulent flow in transonic and supersonic flow is a thrust area for researchers. Whenever the flow experiences an abrupt increase in the area of the enlarged duct, the flow gets significant relief to separate and expand. When the shear layer comes out, it gets divided into two regions: main flow and separated flow. The divided stream line gets reattached with the duct and forms a recirculation zone where the pressure is lower than ambient pressure, resulting in significant drag. This study focuses on base pressure control through quarter-circle rib as a passive control mechanism. Accordingly, a comprehensive numerical simulation was carried out at screech-prone Mach number M = 1.6 for various radii 1 mm, 2 mm, 3 mm, and 4 mm for duct lengths in the range from L = 1D to 6D and nozzle pressure ratios from 3 to 11. Results indicate that for the same range of the rib radius, duct lengths, and level of expansion, there is a progressive increase in the base pressure when rib locations are moved downstream from 0.5D to 3D. The maximum rise in the base pressure is achieved when the rib is located at 66 mm from the base region. A rib with a radius of 1 mm is inadequate for the entire range of rib placement in the present study except when the rib is 11 mm from the base. It can be concluded that a rib of a 1.5 mm radius will be sufficient to neutralize the suction created due to the flow separation. The user can decide on the rib dimension, location, and nozzle pressure ratio based on their requirements.

Published: February 2025

This article presents an innovative system for recovering thermal energy using a thermoelectric generator (TEG). The system uses waste heat from a water heater to generate electricity. A maximum temperature gradient of 96.5°C is maintained between the hot surface of the water heater and a heat sink, which is a cold-water cavity cooling the TEG to maintain a good temperature differential. The system produces about 350% more energy than the water heater consumes. The electricity generated is regulated by a DC-DC converter and stored in a Li-ion battery, ensuring stable operation even after the water heater has been shut down. This technology reduces energy costs and improves the efficiency of heating systems by recovering lost energy, while reducing external energy dependence of the water heater.

Published: February 2025

In the current study, the materials to be used for permeable medium layer are ceramics, carbon steel, and copper. Saturated vapor flowed over the layer that is in the sudden changed channel inside a chamber. In the permeable medium material, an analysis of the impact of each heat conductivity on the temperature distribution, temperature spectrum, and heat exchange rate that occurs in the permeable medium is carried out. Analysis was performed using ANSYS Workbench 18.1 software. The results of the analysis show that the heat conductivity, without the sudden changed channel impact, proportionally influences the heat exchange and temperature spectrum in permeable ceramics and permeable carbon steel medium under saturated vapor flow. However, the heat conductivity and the sudden changed channel impact greatly influence the temperature spectrum, heat exchange rate, and the temperature profile in all of segments of the chamber system.
