Authors: Ginting Septiana Maria Deba , Februhartanty Judhiastuty , Khusun Helda
Published: February 2024

Background: Many low- and middle-income countries are now facing the “double burden” of malnutrition, one of them is overweight/obesity. Over 340 million children and adolescents were overweight and obesity in 2016. Obesity among adolescents may increase, in part due to changes in the food system, which now offers a wide range of ultra-processed foods (UPF) that minimize preparation time. Indonesia has also a large and rapidly growing market for unhealthy drinks, which are sold in various places including schools and hospitals.

Objective: This study aimed to investigate the association of UPF and beverages consumption and other related factors with nutritional status of senior high school students in Pontianak, West Kalimantan, Indonesia.

Methods: This cross-sectional study conducted in Pontianak investigated the association between UPF consumption and nutritional status of SHS students. Data collection was conducted at Imanuel and Petrus SHS Pontianak in June 2023, involving 273 students from grades 10th and 11th. Weight and height measurement was obtained for calculating the BMI for age Z-scores, while UPF and beverages consumption was obtained by FFQ. Structured questionnaire, 24-hours recall, and IPAQ-S were used for assessing sociodemographic status, Total Energy Intake and Physical Activity Level. Data analysis used SPSS version 26.

Results: The result found 40.3% of students were overweight-obesity; 51.6% consumed excessive UPF and beverages. It showed an inverse association between UPF consumption and nutritional status. The study identifies UPF and beverages consumption, gender, mother's education level, and family income as factors associated with nutritional status among adolescents.

Conclusion: The consumption of ultra-processed Foods was high, with the highest UPF intake came from snacks and sweets (22.4%). There was inverse association between UPF and beverages consumption with nutritional status. There was also significant association between UPF and beverages, gender, mother education level and family income with nutritional status.

Faz-se necessário acompanhamento com gastroenterologista e equipe multidisciplinar para individuização de cada caso e instituição de tratamento adequado.
Three dimensional convolutional neural network-based automated detection of midline shift in traumatic brain injury cases from head computed tomography scans
Authors: Agrawal Deepak , Joshi Sharwari , Bahel Vaibhav , Poonamallee Latha , Agrawal Amit
Published: February 2024

Objectives:

Midline shift (MLS) is a critical indicator of the severity of brain trauma and is even suggestive of changes in intracranial pressure. At present, radiologists have to manually measure the MLS using laborious techniques. Automatic detection of MLS using artificial intelligence can be a cutting-edge solution for emergency health-care personnel to help in prompt diagnosis and treatment. In this study, we sought to determine the accuracy and the prognostic value of our screening tool that automatically detects MLS on computed tomography (CT) images in patients with traumatic brain injuries (TBIs).

Materials and Methods:

The study enrolled TBI cases, who presented at the Department of Neurosurgery, All India Institute of Medical Sciences, New Delhi. Institutional ethics committee permission was taken before starting the study. The data collection was carried out for over nine months, i.e., from January 2020 to September 2020. The data collection included head CT scans, patient demographics, clinical details as well as radiologist’s reports. The radiologist’s reports were considered the “gold standard” for evaluating the MLS. A deep learning-based three dimensional (3D) convolutional neural network (CNN) model was developed using 176 head CT scans.

Results:

The developed 3D CNN model was trained using 156 scans and was tested on 20 head CTs to determine the accuracy and sensitivity of the model. The screening tool was correctly able to detect 7/10 MLS cases and 4/10 non-MLS cases. The model showed an accuracy of 55% with high specificity (70%) and moderate sensitivity of 40%.

Conclusion:

An automated solution for screening the MLS can prove useful for neurosurgeons. The results are strong evidence that 3D CNN can assist clinicians in screening MLS cases in an emergency setting.
The Conceptual Basis of Popular Science Events in the Modern Library Space
Authors: Pleshakova Maria A. , Kurmysheva Lidiya K.
Published: February 2024

The article is devoted to the methodological analysis of the concept of “popular science event”. The study begins with a bibliometric analysis of publications from Russian Science Citation Index and scientific electronic library eLIBRARY.RU, selected by the search prescription “popular science event”. The main research method was the analysis of the flow of publications related to the thematic area “popular science events” from January 1, 2008 to September 14, 2023. A total of 75 relevant articles were selected for the research topic. Based on the general bibliometric indicators of the selection of publications on the topic of popular science events, conclusions were drawn about the local nature of the analyzed topic. The greatest interest in this topic was aroused by specialists in the field of pedagogy, cultural studies and economics. In general, this area of activity is now relevant, but it is not sufficiently developed in methodological terms. There is no definition of this concept in publications, however, due to the development of communicative practices in which the genre of popular science event is used, its introduction into the terminological range is required. Therefore, the next stage of the research is the operationalization of the concept under study. The greatest attention is paid to the analysis of publications from the field of library science. The dictionary articles devoted to the interpretation of the main component of the considered concept “event”, including the specific context of use — “library event”, are also regarded. Popular science events held in libraries have different goals, objectives, content and composition of participants. Depending on the content of the listed characteristics, such events become important for self-education of people and assistance to the scientific community in popularization of science.

The article may be useful for specialists whose work is related to the organization of popular science events in libraries and popularization of scientific knowledge in general.

This study investigates how the dietary supplement silymarin, interacts with gut microbiota, with a focus on aging populations. Using advanced techniques such as next-generation sequencing, NMR, and LC-MS, we analyzed the dual impact of the gut microbiome on silymarin metabolism and the effect of silymarin on the microbiome's structure and function. The research revealed that silymarin significantly alters the metabolism of the gut microbiota, decreasing short-chain fatty acid production (acetate, butyrate, propionate) and glucose utilization. Importantly, the study unveiled age-related differences in silymarin catabolism. Healthy elders (70-80 years) showed a significant increase in a specific catabolite associated with Oscillibacter. Conversely, ealthy young donors (12-45 years) exhibited faster breakdown of silymarin components, particularly isosilybin B, which negatively correlated with higher abundance of Faecalibacterium and Erysipelotrochaceae UCG-003 in the healthy young donors. This study provides important insights into the age-dependent modulation of microbiome functionality in the metabolism of dietary flavonolignans, which has important implications for developing age-specific nutritional strategies.
Quantifying Near-Symmetric Molecular Distortion Using Symmetry-Coordinate Structural Decomposition
Authors: Kingsbury Christopher J. , Senge Mathias O.
Published: February 2024

We imagine molecules to be perfect, but rigidified units can be designed to bend from their ideal shape, discarding their symmetric elements as they process through vibrations and larger, more permanent distortions. The shape of molecules is either simulated or measured by crystallography and strongly affects chemical properties but, beyond an image or tabulation of atom-to-atom distances, little is often discussed of the accessed conformation. We have simplified the process of shape quantification across multiple molecular types with a new web-accessible program – SCSD – through which a molecular subunit possessing near-symmetry can be dissected into symmetry coordinates with ease. This parameterization allows a common set of numbers for comparing and understanding molecular shape, and is a simple method for database analysis; this program isavailable at https://www.sengegroup.eu/scsd

The emerging ultrawide-bandgap AlGaN alloy system holds promise for the development of advanced materials in the next generation of power semiconductor and UV optoelectronic devices. Within this context, heterostructures based on III-nitrides are very popular in view of their applications as electronics and optoelectronics components. AlGaN-based deep UV emitters are gaining visibility for their disinfection capabilities. Likewise, high electron mobility transistors are attracting increasing attention owing to their superior electron transport which yields high-speed and high-power applications. Those devices are conventionally made of AlGaN/GaN heterostructures grown on foreign substrate. However, structural defects, including stress induced by a mismatch in unit cell parameters and the presence of dislocations, can not only decrease the efficiency of the light emitters (by facilitating the non-radiative recombination of electron-hole pairs), but also impede electron mobility within the two-dimensional electron gas at the AlGaN/GaN interface. Therefore, the significance of obtaining high-quality AlGaN layers becomes evident. Including a thin AlN interlayer between the GaN buffer layer and AlGaN is a possible answer to address these drawbacks. Not only we show that a thin AlN layer, approximately ≤ 3 nm in thickness, between the GaN buffer and AlGaN layers, is effective in decreasing the dislocation densities in the AlGaN layer. Still, this is responsible of an increase in the electron mobility of the resulting heterostructure compared to a classical AlGaN/GaN heterostructure.

This work is devoted to evaluating the relationship between oxygen content and catalytic activity on the CO oxidation process of the 6H-type BaFeO3-δ system, showing that a higher Fe oxidation state improved the catalytic performance of the oxides, confirming the involvement of the lattice oxygen in the catalytic process. The redox behavior of the catalyst, followed mainly by neutron thermodiffraction under different atmospheres, allows us to determine the structure of the anionic and cationic sublattices showing a structural transition from the hexagonal symmetry (P63/mmc) of the ideal 6H type to orthorhombic (Cmcm) caused for the octahedra distortion when the Fe3+ concentration increases up to 40% (δ values higher than 0.2) The redox process is topotactic and the 6H basic structure is maintained in the δ range (0<δ<0.4).

While landfilling remains the most economically viable and commonly employed method of waste disposal, it poses potential risks of environmental degradation, including foul odor emission, biogas production, and the generation of leachates carrying a significant pollution load. Leachates, upon infiltrating the subsoil, contribute to a profound degradation of groundwater. This study focuses on assessing the impact of leachates from the public landfill of Bouguerguer (wilaya of Guelma) on groundwater and surface water. Two sampling campaigns were conducted, with the first involving 5 samples and the second comprising 8 samples, both carried out in 2018. Analytical results reveal that water sourced from wells, springs, and downstream surface water from the technical landfill Bouguerguer is heavily contaminated with organic matter and metallic trace elements (Cr+6, Pb+, Fe+3, and Ni). Levels of organic matter (BOD5: 50 mg/l - 10 mg/l, dissolved oxygen: 0.5-9 mg/l) are notably elevated in surface and groundwater, respectively. Additionally, concentrations of trace metal elements (Cr+6: 0.075-2.45 mg/l, Pb+: 0.03-1.16 mg/l, Fe+3: 0.006-7.07 mg/l, Ni+: 0.29-25 mg/l) significantly surpass the standards set by the World Health Organization (WHO). Consequently, these findings substantiate our hypothesis that degraded groundwater and surface water contribute significantly to the prevalence of diseases in Guelma Wilaya. This study emphasizes the urgent need for local authorities to implement preventive measures to mitigate pollution and to rehabilitate the landfill in accordance with international standards.

Published: February 2024

The legal foundation is one of the most important sources of law that has been emphasized in several legal theories. However, concepts regarding legal foundation are still heavily debated and intertwined with other legal principles, legal values, legal norms, legal theorems, and legal rules. Foundation, principles, and norms are general concepts discussed in the law field as a separate point of discussion in the study of law, especially in legal theory.This showcases that the knowledge regarding concepts and the standing of different principles, values, norms, and rules are important in studying a particular field of law. However, in practice, most legal scholars and professors in the field of law are still unaware of such concepts that often overlap with one another. Generally, foundations are meta values from principles, principles are the meta values of norms, and norms are meta values of a rule. In comparison, values are the equivalent of principles and fundamental values. A theorem is the equivalent of a norm, which is embodied in a rule, and the rule itself is the most concrete implementation of a principle, which may be in the form of a written or unwritten rule. This paper aims to explore the relationship between justice, corrective justice, restitution, and unjust enrichment. It will discuss how fundamental values, principles, and norms serve as meta-values in achieving justice. Additionally, it will examine the role of corrective justice in providing restitution for cases of unjust enrichment.
Stability of minimal surfaces in the sub-Riemannian manifold $\widetilde{E(2)}$
Authors: Petrov Eugene , Havrylenko Ihor
Published: February 2024

In the paper we study smooth oriented surfaces in the universal covering space of the group of orientation-preserving Euclidean plane isometries, which has a three-dimensional sub-Riemannian manifold structure. This structure is constructed as a restriction of the Euclidean metric on the group to some completely non-integrable left invariant distribution. The sub-Riemannian area of a surface is then defined as the integral of the length of its unit normal field projected orthogonally onto this distribution. We calculate the first variation formula of the sub-Riemannian surface area and derive the minimality criterion from it. Here we call a surface minimal if it is a critical point of the sub-Riemannian area functional under normal variations with compact support. We show that the minimality in this case is not equivalent to the vanishing of the sub-Riemannian mean curvature. We then prove that a Euclidean plane is minimal if and only if it is parallel or orthogonal to the $z$-axis (where the $z$-coordinate corresponds to the rotation angle of an isometry). Also we obtain the minimality condition for a graph and give examples of minimal graphs. The examples considered in the paper demonstrate, in particular, that the minimality of a surface in the Riemannian (in this case Euclidean) sense does not imply its sub-Riemannian minimality, and vice versa. Next, we consider the stability of minimal surfaces. For this purpose, we derive the second variation formula of the sub-Riemannian area and show with it that minimal Euclidean planes are stable. We introduce a class of surfaces for which the tangent planes are perpendicular to the planes of the sub-Riemannian structure, and call them vertical surfaces. In particular, for such surfaces the second variation formula is simplified significantly. Then we prove that complete connected vertical minimal surfaces are either Euclidean planes or helicoids and that helicoids are unstable. This implies a following Bernstein type result: a complete connected vertical minimal surface is stable if and only if it is a Euclidean plane orthogonal to the $z$-axis.
ОСОБЕННОСТИ РАСПРОСТРАНЕНИЯ АЭРОЗОЛЬНЫХ ЧАСТИЦ В ТЕХНОГЕННЫХ УСЛОВИЯХ

Published: February 2024

В работе обсуждается динамика аэрозолей в приложении к распространению воздушно-капельных вирусных инфекций в условиях, когда следует учитывать взаимное движение исследуемых объектов. Данная особенность наиболее сильно должна проявляться в городских условиях, где разнообразные транспортные потоки являются неотъемлемой частью среды обитания современного человека. Рассматривается движение отдельных частиц в двухмерной геометрии под действием силы тяжести и трения, а также внешнего электростатического поля. В рамках развиваемой модели исследуется влияние начальных условий, обусловленных физиологическими процессами дыхания, и состоянием окружающей среды на динамику распространения выдыхаемых аэрозолей. Произведена оценка расстояний, на которые могут распространиться аэрозольные частицы в зависимости от размеров и начальных скоростей частиц. Показано, что более крупные частицы распространяются на большие расстояния, тогда как более мелкие частицы «вморожены» в окружающую среду и могут распространяться только с потоками воздуха. В приложении к передаче вирусных инфекций это означает совершенно разные виды транспортировки вирусов в зависимости от размеров и вида дисперсной фазы. Полученные результаты были применены к анализу особенностей распространения вирусов в условиях метрополитена.

Pro-environmental elements in the business model of medium and large Polish road freight carriers
Authors:   Uniwersytet Gdański, Sopot, Letkiewicz Andrzej
Published: February 2024

Purpose: The policy of sustainable development places requirements on businesses to reduce their negative environmental impact. One of the sectors of the economy that is responsible for greenhouse gas emissions is road transportation. Consideration of the European Union’s environmental goals is forcing road carriers to have environmental measures built into their business models. The purpose of the study was to learn how road carriers can reduce their negative environmental impact so that they can fit in with the goals of the environmental policy and to learn about the regulatory tools that the road carriers expect to be able to support these activities. Design/methodology/approach: Data for this study was collected in computer-assisted telephone interviews (CATI). The study was conducted in late 2021 and early 2022 by a Polish company that was responsible for the selection of the sample and the collection of the data. The survey was conducted on a sample of 146 medium and large Polish road freight carriers and was a continuation of a study carried out on the same sample of entities conducted in late 2019 and early 2020 using the same technique. Findings: As part of their fleet policy, in order to fit in with environmental goals, carriers base their business models on the purchase of new means of transportation that meet increasingly stringent emission standards and reinforce environmentally friendly attitudes by buying means of transportation with smaller engine displacement that is tailored to the needs arising from their operations. Pro-environmental operational activities of medium and large Polish road freight carriers involve the use of solutions that change the composition of exhaust gases (AdBlue) and reduce fuel consumption (lowering rolling resistance – energy-efficient tires and lowering air resistance – fairings), and the acquisition of pro-environmental driving skills (eco-driving). Other environmentally friendly measures are to increase the utilisation of the vehicle capacity (cargo consolidation) and to eliminate empty runs by looking for cargo to be carried on the way back and using route planning software. Originality/value: The paper indicates the methods to reduce the negative environmental impact considered in the business models of medium and large road freight carriers, so that they fit in with the environmental policy goals, and indicates their expectations associated with the support for the achievement of zero-emission transportation. The results can be useful in the adoption on both the European and Polish level of policies leading to a zero-carbon economy. Keywords: sustainable business models, road freight transport.

Overview and prioritization of critical success factors in NPD models for the chemical industry
Authors:   Opole University of Technology, Lapunka Iwona , Barton-Pudlik Joanna ,   Johnson & Johnson MedTech, Solothurn, Switzerland, Jagoda-Sobalak Dominika ,   Opole University of Technology
Published: February 2024

Purpose: The purpose of the article is to review NPD models and identify critical success factors for new product development in the chemical industry. Design/methodology/approach: The systematic review of the literature was applied in the paper and the AHP method was used to build a hierarchical model for determining the importance of CFSs. Findings: The paper characterizes the concepts of new product development and general models of new product development. Older (pre-2000) and newer generation studies were included among the models described. Data analysis of new product development studies in the chemical industry was carried out. Based on the literature analysis, key factors determining the success of a new product were selected, with a division into general and typical elements of the industry in question. Research limitations/implications: The prioritization of CFSs will allow in the next step the analytic hierarchy process of NPD models, on the basis of which it will be possible to determine which of the analyzed models is most suitable for chemical products. Practical implications: Most chemical products are designed using trial-and-error techniques based on experimentation, making NPD in the chemical industry more iterative. This often involves generating a huge number of chemical components, and this means that the search area can be very large. It is therefore reasonable to look for decision support tools to facilitate the selection of necessary components. The selection of chemical product ideas should be based not only on an analysis of what is possible to produce, but also on an analysis of what the market would like to buy. The specifics of chemical products and changes related to 21st century trends are forcing the determination of appropriate CFSs for the chemical industry. Originality/value: The chemical industry is one of the world’s key industries, whose products are used in almost every area of life. Despite this high relevance, there has been no attempt to date to systematize the issues of developing new product lines or portfolios in this industry. Keywords: new product development model (NPD), critical success factors (CFSs), analytic hierarchy process (AHP), prioritization, chemical industry.

War in Ukraine and new management paradigm
Authors:   War Studies University, Management and Command Faculty, Warsaw, Maśloch Piotr
Published: February 2024

Purpose: The main aim of the article was to present an innovative management approach involving the implementation of selected features of a turquoise organization into a militarized organization (the Armed Forces of Ukraine). Design/methodology/approach: The subject matter addressed in the article is so new and original that, in principle, there is a powerful research gap in the subject area of the author's interest. In view of the above, the content of the publication and the considerations carried out were based primarily on the author's own work, on available reports and expert opinions and on available scientific publications. Findings: The publication makes several important findings: first, it was pointed out that there are a number of common features between command and management. Second, the basic features of a turquoise organization are presented, and an implementation of these features to an inherently authoritarian organization (the armed forces) is made. Thirdly, it was found that in view of the Russian army's multiple superiority, there must be other factors that build Ukraine's superiority, i.e. precisely, for example, management, self-motivation, responsibility, i.e. precisely the characteristics of a turquoise organization. Research limitations/implications: The main research limitation is that the issue addressed is a new topic that has not yet been widely discussed in the literature. Moreover, the concept of implementing the features of a turquoise organization into an organization with an authoritarian character is the author's proposal on this issue - the validity of this approach is evidenced by the analysis of the armed conflict between Russia and Ukraine. Practical implications: The concept of implementing the features of a turquoise organization into a more autocratic organization is a proposal for managers and commanders to make changes to operate more efficiently. Originality/value: The topic addressed is new and original, not previously addressed. The article presents an original concept of using the characteristics of a turquoise organization in the process of managing organizations, even those of an authoritarian nature.

Proposal for an expert system to aid decision-making in the design and management of flexible manufacturing systems
Authors:   University of Szczecin, Institute of Management, Musial Wojciech , Witek Jolanta ,   The Jacob of Paradies University
Published: February 2024

Purpose: The objective of this article is to introduce a concept for facilitating decision-making processes in the design and management of flexible manufacturing systems. This concept aims to minimize the risk of either overestimating or underestimating the flexibility and efficiency of production potential. Design/methodology/approach: The proposal involves the utilization of a hybrid expert system, incorporating a combination of rules, scenarios, and semantic schemes to construct a comprehensive knowledge base. This system also integrates fuzzy logic, artificial neural networks, and agent systems with expert systems. Findings: The proposed concept of a hybrid expert system allows for the management of flexible manufacturing systems across various levels, including strategic, operational, and technological aspects of production organization and management. Practical implications: The article has broad applications as it is specifically tailored to address the intricacies of flexible manufacturing systems and expert systems for facilitating decision-making processes within the production context. Originality/value: Each management level possesses its distinct characteristics, methods, and tools that can be seamlessly integrated through the use of hybrid expert systems. Category of the paper: Research paper, conceptual paper. Keywords: Expert systems, flexible manufacturing system, Industry 5.0, production management and engineering.
Active and passive approach to opportunities in crises events
Authors:   Czestochowa University of Technology, Otola Iwona
Published: February 2024

Purpose: The primary purpose of the paper is to discuss active and passive approaches to opportunities in strategic management. Crisis situations usually have negative consequences for companies but are also an impetus for implementing changes and seeking opportunities. Theoretical considerations focus on the identification of opportunities in strategic management and their impact on strategy reorientations. The theoretical verification of the above issues allowed to pose a research question: how did IT companies seize opportunities in the face of recent crisis events? Design/methodology/approach: In the article the theoretical concept of R. Krupski in its approach to opportunities was applied. To verify this concept qualitative research - case studies on the example of selected companies in the IT sector was used. Findings: According to theoretical considerations, a passive-external approach to opportunities should be the natural approach to crisis events. The cases presented indicate that the approach to opportunities depends on the specifics of the business, the experience gained and knowledge possessed, as well as the ability to find oneself in a dynamic environment. Both the passive- internal approach and the active-internal approach to opportunities are feasible in times of crises. Research limitations/implications: The qualitative research conducted is a prelude to further quantitative research on how companies seize opportunities in times of crisis. This research applies only to the IT sector and is worth extending to other sectors. Originality/value: The novelty of this article is the consideration of opportunity and how it is perceived under crisis conditions. These issues should be considered particularly relevant in the framework of business operations, especially in view of recent events, i.e. the COVID-19 pandemic and the war in Ukraine. Keywords: crisis, opportunity, approach to opportunity, IT sector. Category of the paper: research paper.
Forms of cooperation aimed at implement sustainable development in urban areas
Authors:   Faculty of Management, Częstochowa University of Technology, Szczepańczyk Marta
Published: February 2024

Purpose: The aim of this paper is to identify opportunities for cooperation and to show the role it plays in the context of sustainable development in urban areas. Design/methodology/approach: Based on a review of the available literature and the current legislation, the paper discusses the basic concepts of sustainable urban development and addresses the key objectives of cohesion policy in this regard. Thanks to the information made available in the EU websites, the European Urban Initiative, a portal providing solutions aimed at promoting cooperation between cities and supporting them in the implementation of sustainable development measures, has been characterised. Using the case study method, a detailed description/analysis of three selected projects (implemented as a response to challenges of a local nature and in line with the objectives of cohesion policy) was carried out. The projects have been recognised as innovative and easily replicable by other entities. Findings: The deliberations presented in this paper have made it possible to point out opportunities for cooperation, both between cities and partnerships within them. In this respect, particular emphasis has also been placed on the benefits of cooperation in developing solutions to the challenges of the local environment. Research limitations/implications: The study is qualitative in nature. Among the main limitations, it is worth mentioning the shortcomings of the projects’ documentation used in the case study. It should also be assumed that the next study in this area will be of a quantitative nature, where the interrelation between the use of territorial instruments and the degree of implementation of strategic objectives will be verified. Social implications: The contents discussed below prove the validity of disseminating the principles of sustainable development in urban areas, both from the point of view of developing the various aspects of economic life and of involving residents in this process. At this point, it is also worth referring to the solutions indicated in the case studies, which have been introduced to meet the needs of the local community. Originality/value: The paper presents the cities’ possible options of implementing innovative solutions in the field of sustainable development. In this regard, digital platforms were pointed out, where relevant knowledge is gathered and disseminated, including know-how. Keywords: Sustainable urban development, partnership, European Union. Category of the paper: Case study, literature review.
Business demography in Poland: a DSGE approach
Authors:   AGH University of Krakow, Zając Paweł
Published: February 2024

Purpose: This article explores the relationship between macroeconomic factors and business demography in the Poland in years 2012-2023. Recent events, such as the COVID-19 pandemic and the war in Ukraine, have introduced unique challenges to the Polish economy. Understanding these dynamics is essential for informed decision making. Design/methodology/approach: The objectives of the paper are achieved using the DSGE approach with fixed number of firms. In the given model, the firm creation process is perceived in a procyclical way using the sunk entry cost mechanism. Findings: Key findings include the impact of negative productivity shocks on new firms, leading to increased costs and reduced investment attractiveness, resulting in a decline in the total number of companies. In addition, increased public consumption drives up production levels, affecting interest rates and new business opportunities. Technological shocks affect prices and inflation, influencing the number of new companies. Tightening monetary policy impacts capital returns and employment levels. This stimulates the emergence of new firms. Research limitations/implications: Research limitations are strictly related to the limitation of the tool used. Among the limitations of DSGE models are simplifying assumptions (including perfect rationality, representative agents, and complete markets), lack of detail in the financial sector detail, homogeneity between agents, exogeneity of shocks, calibration, and estimation challenges. Despite these limitations, DSGE models have become a cornerstone of modern macroeconomic analysis and policy evaluation. Social implications: The findings have important policy implications. Policymakers should consider the potential consequences of their decisions on the business environment, especially in terms of labor market regulations, public spending, and monetary policy. Originality/value: There are no or few research papers concerning business demography in Poland using the DSGE approach. Keywords: business demography, DSGE, procyclical entry. Category of the paper: Research paper.
