In the wake of the IT revolution of recent decades, Polish companies have experienced changes, such as the obligation to report financials in purely electronic form. This shift creates benefits but is also a source of challenges. The authors' inspiration for this research stems from the recognition of a clear research gap in the literature relating to the electronic reporting of micro and small companies. The article aims to verify how Poland's smallest companies covered by reporting obligations cope with the compulsory compilation, signing and publication of financial statements solely by electronic means. The study was qualitative in nature, followed a case study methodology, and concerned two Polish micro-companies. The results show that the entities analyzed essentially do cope with e-reporting. Certain attributes of these reports - - such as timeliness or completeness, are questionable, however. The results contribute to the understanding of the financial reporting practice by micro companies in Poland. They can indicate directions for changes in the actions taken by those involved in corporate reporting. Cognizance of this issue can also provide the regulator with directions for regulatory changes.

Abstract: The pulp and paper industry both uses and produces large amounts of energy and rising fuel prices bring along significant challenges to the sector. Several strategies can be applied in order to remain competitive e.g. an increase in energy efficiency, a switch in fuel and/or a novel energy conversion technology. In this study, we investigate if improved energy conversion strategies can reduce energy costs, primary energy use and CO2 emissions of paper mills within different European countries (The Netherlands, Poland and Sweden). Our results show that differences in history and availability of resources has led to different conversion strategies in the three countries. We found that a natural gas combined cycle, which is largely implemented in The Netherlands due to long term domestic availability of natural gas, has the lowest primary energy demand. Due to a long history of low electricity prices, CHP has not been common in Sweden. Many Swedish mills use biomass as an energy source and due to low CO2 emissions of the national grid the CO2 emission profile of the Swedish paper industry is very low. Our results imply that future conversion routes for the Swedish paper and board industry are again wood based; in case of increasing electricity prices these would be biomass gasification based CHP solutions. With a reduction of 800kg CO2/ton paper on average, a switch from coal to biomass would reduce CO2 emissions in the Polish pulp and paper industry with approximately 0.6Mton/year. A carbon price of 20–25€/ton would, according to our results, be enough to provoke this switch. Due to the high share of natural gas, the CO2 emission reduction potential of the Dutch paper industry (1.5Mton/year) is even larger than in Poland. Due to high biomass prices and relative low CO2 emission profile of natural gas, a carbon prices of more than 60€/ton CO2 would be needed to provoke a switch in The Netherlands. Provided with few alternatives, the most effective strategy in The Netherlands would be an increase in energy efficiency. [Copyright &y& Elsevier]

Abstract: Heterozygous familial hypercholesterolemia (HFH) affects on average 1 in 500 individuals in European countries, and it is estimated that HeFH in Poland may affect more than 80,000 people. Cardiovascular mortality in individuals with FH between 20 and 39 years of age is 100 times higher than in the general population. HFH is a relatively common lipid disorder, but usually still remaining undiagnosed and untreated. A very high risk of cardiovascular diseases and a shortened lifespan in patients with this condition require early diagnosis and intensive treatment. The aim of the position paper was to present the importance and scale of this problem in Poland, which has not been raised enough so far, as well as the recommendations of diagnosis, treatment and prevention methods.

Abstract: Familial hypercholesterolemia (FH) affects on average 1 in 500 individuals in European countries, and it is estimated that FH in Poland may affect more than 80,000 people. However, in Poland, only about 20% of the population is estimated to have been diagnosed with FH, of which only a small number receive adequate treatment. FH results in more rapid development of atherosclerosis and is associated with a high risk of cardiovascular events. Atherosclerosis develops beginning in childhood in patients with FH and reaches advanced stages before clinical manifestations develop. Inadequate diagnostics and treatment of FH in Polish children suggests a need for raising the level of awareness and understanding of the condition in both society and among health professionals. These recommendations present the current epidemiological status, guidelines for diagnosing FH in Polish children and adolescents, and effective treatment options. [Copyright &y& Elsevier]

Abstract: Currently the amount of produced packaging waste, especially that of paper, cardboard, glass and plastics, is increasing year by year. Increasing packaging quantity has forced countries of the European Union to face this problem. The issue is reflected in EU legislation. The European Parliament and further amended by Directives 2004/12/WE and 2005/20/WE, belongs to binding resolutions passed by the European Union. The leading principle of the Directives was to introduce the obligation to provide adequate levels of waste packaging recovery and recycling. The obligation was defined as the percentage of waste packaging recovery and recycling which has to be achieved by EU member countries in relation to the aggregate weight of packaging introduced into the market. Aspiring to join the European Union, Poland was obliged to comply with the environmental protection requirements valid in the Community. Since 1 January 2002, the annual recycling levels of waste packaging are defined in the Ordinance of the Council of Ministers of 30 June 2001. The aim of the present work is to discuss and compare the required and achieved recycling levels of waste packaging (made of plastic, aluminium, paper and cardboard and glass) in Poland in the years 2002–2007 under the influence of EU directives. Featured data show that the required levels of recovery and waste packaging recycling were met and even exceeded in some cases. This result was influenced by the fact that Poland has been a member of the European Union since 1 May 2004. Hence, actions were enforced in Poland pertaining to waste packaging management as well as an obligation to the recycling levels dictated by European directives. An additional stimulus was constituted by a product charge for failing to comply with the recycling target levels. [Copyright &y& Elsevier]

Innovativeness is important for the success and performance of firms on both the domestic and international markets. The majority of firms with a solid foothold on the market acknowledge the need for innovation as the driving force of organic growth and the way to distinguish themselves from the competition. This paper is aimed at analyzing both the internal and external factors that support the innovativeness of companies and the impact of these factors on the performance of enterprises. The methodological framework of research is of a deductive nature and the existing theories of innovativeness were availed of for the purposes of research on these particular phenomena. By availing of survey responses from personnel directors, heads of HR departments, while also specialists of the field of HR among 179 enterprises from various sectors, evidence was established in the cases of (1) the positive relation between external factors and the internal processes supporting the innovativeness of companies, while also (2) the positive relation between external and internal factors supporting innovativeness and the market situation, economic efficiency and the development of companies. The herein paper makes a theoretical and empirical contribution in terms of research into the innovativeness of enterprises. [ABSTRACT FROM AUTHOR]

The paper presents the results of a study on the use of the online service e-Tax Office (hereinafter e-TO) recently made available by the Polish Ministry of Finance to, inter alia, implement the concept of Polish revenue authorities e-communication with taxpayers. To achieve the objectives assumed, the following research methods were used: multiple case study, literature study, analysis of relevant legal regulations, and own observation method. As a result of the study, it has been found that the e-TO, developed at high expense, did not meet the expectations in any of the cases analyzed, as communication between the Tax Office and the taxpayers in ongoing cases was still carried out in traditional 'paper-based' form; what is more, it was the revenue authorities themselves, who initiated paper-based communication, as opposed to contacting the taxpayer electronically. The study also resulted in an attempt to identify some of the limitations hindering the taxpayer and the tax office e-communication via e-TO. [ABSTRACT FROM AUTHOR]

The industrial sector absorbs a significant amount of energy and solutions are still being sought, the use of which will allow energy consumption during production processes to be reduced, but which will not influence on the quality of the final product or an order's completion time. One solution is to change the technology in the production process, but such a drastic decision would require a detailed analysis of the profitability of an investment. This article analyses movement in production technology processes towards additive manufacturing (AM) technologies in terms of reducing energy consumption. This paper has used literature studies to describe AM methods, in terms of energy consumption in production companies and a questionnaire survey, which was conducted within 125 automotive manufacturing companies in western Poland and finally for further analysis data from the small and medium sized enterprises (SMEs) were selected in order to determine the impact of the use of AM technology on energy consumption. This sector in particular needs to conduct energy consumption reducing activities at a time when Europe is threatened with massive increases in energy prices. Additionally a statistical analysis was also conducted using correlation coefficients. The results show that the SMEs surveyed, which bore the highest costs of energy consumption in production, declared that they were not interested in implementing AM technology while other companies, incurring high energy consumption costs for illuminating their production halls, saw the benefits of implementing AM and were able to reduce production costs in the assembly stage, use material more effectively and have greater freedom in the design and customization of their products, according to specific customer requirements. It was also determined that managers of manufacturing companies, who are interested in implementing AM would also like to implement water or heat recovery systems. • This paper explores the energy consumption in the context of the implementation of AM. • Employs the empirical analysis Polish SMEs (automotive industry) • Provides the actions taken by manufacturing enterprises to reduce energy consumption • Determines benefits of implementing AM in the automotive industry in the context of energy consumption • The media consumption monitoring system implemented in production processes enhances awareness of energy consumption.

• Pulmonary complications of systemic scleroderma are responsible for up to 60% of patients' deaths. • For many years, most centers considered systemic scleroderma a contraindication to lung transplantation. • We proved that lung transplantation in this group of patients is possible with acceptable 1-year results. • More studies addressing the issue of lung transplantation in patients with systemic scleroderma are needed to establish more precise eligibility criteria for transplantation. Pulmonary complications of systemic scleroderma (SSc), such as interstitial lung disease and pulmonary hypertension (PH), are responsible for up to 60% of deaths among patients. For many years, most centers considered SSc a contraindication to lung transplantation (LTx); however, recent publications show that appropriately selected SSc candidates for LTx give results comparable to patients with idiopathic PH or idiopathic pulmonary fibrosis. This paper presents the cases of a 60-year-old male patient (patient 1) and a 42-year-old female patient (patient 2) diagnosed with SSc in 2019 and 2013, respectively. In both patients, interstitial-fibrotic changes in the lungs leading to respiratory failure were confirmed by high-resolution computed tomography as well as pulmonary hypertension (WHO group 3), which was also diagnosed during right heart catheterization. In both cases, despite pharmacotherapy, pulmonary fibrosis progressed, leading to severe respiratory failure. The patients were referred for LTx qualification. LTx was possible to consider in patients due to the lack of significant changes in other internal organs. Double LTx was successfully performed in both patients (patient 1—July 19, 2022; patient 2—September 14, 2022). They were discharged from the hospital in good condition on the 22nd and 20th postoperative day, respectively. LTx is a last-chance therapy that saves lives among patients with extreme respiratory failure in the course of SSc. It prolongs and improves the quality of life. The selection of appropriate patients is key to the success of the procedure. [ABSTRACT FROM AUTHOR]

• Transplant recipients of solid organs report better sleep after transplantation. • Females reported a more positive overall impact of transplantation on sleep; however, they experienced worse sleeping hygiene, when asked specifically. • Women get out of bed later than men (30 minutes difference), need more time to fall asleep, and more often experience sleepiness the next day. Males in our study have better well-being the next day. • Older transplant recipients reported more frequent awakenings at night and instances of waking up before the scheduled time. Sleep plays a crucial role in maintaining health. Transplant patients are exposed to numerous stressors and are at risk of sleep disturbances. The aim of this study was to assess the sleep patterns of transplant patients. An anonymous paper survey was carried out among patients from one transplant center in Poland. Respondents were asked about the quality and quantity of sleep and the overall impact of the transplantation on their night rest. Data were collected from June to November 2023. Data were obtained from 212 respondents (122 males and 90 females), aged 48.38 ± 13.68. The positive impact of transplantation on sleep hygiene was indicated by 57.4% of respondents, 28.9% observed no impact, and 13.6% rated the impact as negative. Our study showed that sleep is more satisfying in males than in females (62.8% of males and 46.7% of females). The analysis revealed that 38.9% of females need 30 minutes more than men to fall asleep. Additionally, females tend to get up half an hour later compared to men. About 71.9% of males declared good well-being the next day compared to 62.2% of females. Furthermore females declared more sleepiness the next day. The study also showed that older transplant recipients (over 50 years-of-age) report more frequent awakenings at night. The data collected showed differences in sleep patterns according to gender and age. Females and older patients should be screened for sleep disturbances during post-transplantation care.

• One Polish household wasted 0.56 kg of food per day. • In Polish households, fruit, vegetables, bread are wasted the most during the day. • Household characteristics explain food waste more than individual characteristics. • Single-person households waste more food products and semi-products than other. • On a per capita level Polish households with children waste less food. In Poland, to our best knowledge, none of the scientific publications produced to date have addressed the scale of wasted food in households and the impact of sociodemographic and economic factors on this. This study fills this research gap. The study was carried out in 2019 on a nationwide random-quota sample of 500 households, which are representative of all households. The survey was carried out in the respondents' homes for seven consecutive days. It consisted of an interview conducted by an interviewer (Computer-Assisted Personal Interviews method) and a paper diary completed by the respondents themselves. The aim of the study was to present the volume of wasted food, taking five groups into account,and to examine the impact of the sociodemographic and economic characteristics of the households and the person responsible for preparing meals on food waste. The results show that one person, on average, wasted 62.6 kg of edible food per year (98.2 kg of edible and inedible parts combined). According to the results, the most discarded food products include fruit and vegetables, bread, dairy products, drinks and juices, and cold cuts. Statistical analysis showed that the level of food waste in Polish households is conditioned by characteristics such as household size (persons), the presence and number of children, monthly income, as well as the characteristics of the person responsible for preparing meals, such as age and employment status.

In recent years, the onset of the summer season has inevitably been associated with external threats, such as hydrological drought. Prolonged dry weather conditions result in natural drought symptoms, including a decrease in both surface and groundwater levels, increased water evaporation, and the degradation of essential environmental, economic, and social functions. A negative water balance presents a challenge that, due to water scarcity, is likely to pose a threat not only to the continuity of safe drinking water supply but also to the health and lives of people. In these circumstances, the new directive on the quality of water intended for human consumption imposes on EU Member States the obligation to implement a risk management system throughout the entire water supply chain, from the water abstraction area to the consumer's tap. The paper presents tools and mechanisms employed in risk management for water supply systems and discusses their applicability within the framework of multi-protective barriers. Additionally, it delves into the construction of water supply infrastructure in the city of Głubczyce, located in the southwestern part of Poland. This discussion encompasses research results on the possibilities for diversifying and ensuring the safety of water supplies, with a particular emphasis on the operational reliability of critical infrastructure. The analysis is based on the Shannon-Weaver index and the Pielou dispersion index. The results of this analysis assess the potential for crisis situations in risk management. Taking into account the protection of critical infrastructure to ensure continuous water supplies under appropriate pressure for residents, the need to provide alternative water sources, such as tanks or packaged water, is demonstrated.

According to Directive 2020/2184, each water supplier is required to develop a water supply risk management system, such as the World Health Organization's recommended Water Safety Plan, implement it and apply it to daily water supply practices. An important element of risk management in water supply systems (WSS) is to ensure the supply of water that is healthy and clean, that is, free of all microorganisms and parasites and any substances in quantities or concentrations that pose a potential danger to human health. Ensuring the microbiological safety of water, while minimizing the risks associated with disinfection by-products, is particularly important in extensive WSS, where water can take days to transport, and where hydraulic parameters and sediments deposited in water supply networks favor the growth of microorganisms. This paper proposes an analytical method to support the determination of areas sensitive to the loss of microbiological safety of water, while using the model to optimize the dose of disinfectant at water treatment plants and water chlorination points in the distribution subsystem. The developed methodology is part of a review of operating procedures, especially with regard to minimizing the risk of secondary microbiological contamination of water. The research model took into account the chemical as well as microbiological variability of water quality, its age, and the operational data of the WSS operation collected by the Geographic Information System (location of water quality monitoring points, spatial location of water supply infrastructure facilities), as well as the size of the population potentially exposed to water of uncertain microbiological quality. The result of the analyses is a spatial interpretation of the loss of microbiological safety of water presented in the form of risk maps. [ABSTRACT FROM AUTHOR]

• The amount of separately collected bio-waste, its composition and selected properties are subject to seasonal variations. • Food waste is the main component of bio-waste from each tested site. • Substantial part of contaminants (e.g. plastics, glass) was found in the waste stream. • Waste collected in containers in multi-family housing area the most contaminated. • Heavy metals content of tested samples varied, both in terms of location and season. The progress of civilisation contributes, among other things, to an increase in the mass of waste produced in households. A significant part of it is bio-waste (about 31% in Poland). It is generally agreed that bio-waste is a suitable substrate for valorisation through fermentation with biogas production. Designing new and optimising existing facilities, however, requires precise data on the composition of bio-waste and its properties, which is challenging due to seasonal variability, place of origin (single- or multi-family housing, urban or rural) and collection method. This paper presents the method adopted for conducting the study and the results of an annual, monthly analysis of the morphological composition and selected properties of bio-waste from source-segregated households from 4 rural municipalities and 4 cities, from neighbourhoods with single-family and multi-family housing in Poland. In household bio-waste, the proportion of food waste content ranges from 36.7 to 47.6% (annual average values). The proportion of edible food waste in relation to the total weight of food waste is 5 to 7 times lower. The yearly percentage of garden waste varied from 35.8 to 52.8%. A considerable amount of impurities (such as plastics, glass, and stones) is present in the bio-waste stream. The waste collected in containers in urban areas with multi-family houses is the most polluted (16.6%). The proportion of pollutants in bio-waste collected in bags (rural areas and cities with single-family housing) does not exceed 10%. [ABSTRACT FROM AUTHOR]

• Right to the City as vehicle of urban movements network successful mobilization. • Polish Urban Movements Congress unusual in terms of professionalism and diversity. • In response to growing activists role developers claim their "right to the city" • PZFD organizational platform builds sector credibility & undermine activists' legitimacy. • Developers remain in the incumbent positions, appropriate new norms and practices. The insufficient access to housing and the commercialization of public space are most problematic aspects of urban development in Poland. As we witness the effects of neoliberalization in the urban policy sector – with an increased presence of private corporate actors combined with a withdrawal of the earlier so dominant public authorities – there is still no long-term policy in place to counteract the negative social as well as economic effects on the citizens. To the contrary, existing political order in many cities supports market solutions, while scaling down investments in public space, municipal housing or building for rent. To better explain the dynamics of urban policy, the paper uses a field theory approach (Martin, 2003), to analyse the role of developers and urban grassroots movements in planning and building of Polish cities. Data from formal and informal interviews with developers, urban activists and public authorities are used, supplemented by results of participatory observations at national conferences, government workshops and activists' gatherings. Paper describes the ongoing 'game of the city' (Domaradzka and Wijkström, 2016) in which incumbents defend their dominant position and control over space, while a set of challengers seek to introduce new values and behaviours. It presents the wider context of Polish urban policy field and organizational practices of developers and urban activists to illustrate the field dynamics and actors' changing strategies. The analysis also shows how the dominant narratives are shaped through re-defining the 'right to the city' frame and incorporating it into the developers' agenda. [ABSTRACT FROM AUTHOR]

The company's innovativeness is largely influenced by external factors, which is influenced by the increasing demand for new products, pressure from competition, or accelerating the processes of europeanization and globalization. An enterprise described as innovative is considered to be better and more desirable. Businesses recognize that they need to understand where the market is heading and create products and services that fit with it. The entrepreneurs understand that they need to innovate so as not to be left behind. The aim of the paper was to show the importance of the issues of sustainable development in relation to the innovativeness of Polish enterprises. The paper presents the idea of sustainable development, the concept of innovation and sustainable innovation in business. The theoretical considerations have been extended to the presentation of selected projects for sustainable innovations in enterprises in Poland and around the world. The considerations were also enriched with the results of research conducted among the managerial staff of selected Polish enterprises located in the Silesian Voivodeship. The research was conducted in the period November 2021 - March 2022 among companies that were known to have experience in activities related to sustainable development. The aim of the research was to get to know the awareness of management staff about sustainable development and to find out what importance is given in companies to issues related to sustainable development and sustainable innovation, how it affects their company and what actions are taken to further take into account the principles of sustainable development in their activities.

This paper considers the problem of selecting a state-made electronic document management system (EDMS) using the analytic hierarchy process (AHP) model. The problem of EDMS selection from two available variants is analysed and the selection criteria related are highlighted on the basis of the literature and the authors' experience. Calculations related to pairwise comparisons and prioritisation between criteria and variants form the core of the paper. This problem is only applicable to municipalities in Poland that have implemented an older state-made system; based on pair-wise comparisons, retaining the older system is preferable to implementing the new state-made EDMS because of the lack of integration of the new EDMS with internal systems.

This paper presents the results of primary research involving a survey of Polish passengers during the COVID-19 pandemic. The survey was conducted in January 2022 using the CAWI method on a representative sample of N = 1,129 Polish adults aged 18 to 60. First, means of transport were classified by distance covered into urban, regional and interregional transport. Survey participants were asked a series of questions regarding the use of modern technologies in public transportation. Before that, however, the frequency of urban (agglomeration), regional, interregional (transregional) and private transport use during the COVID-19 pandemic was examined. More than half of respondents said they used modern technology across all modes of public transportation, and about a quarter said that while they had not yet used these technologies, they intended to do so. Only about 15% of respondents replied they did not use and did not intend to use modern technologies, regardless of the mode of transport. The aim of the paper is to examine the use of modern technologies by passengers in the era of the COVID-19 pandemic. Research results may help to influence passengers' purchasing decisions and to improve services offered by carriers in accordance with the objectives of long-term transport policy of both the European Union and Poland related to sustainable transport development.

This paper presents the results of primary research involving a survey of travelers in Poland during the COVID-19 pandemic. The survey was conducted in January 2022 using the CAWI method on a representative sample of n =1,129 Polish adults aged 18 to 60. As many as 74% of respondents believe that the COVID-19 pandemic has changed traveler preferences with regard to urban, regional and trans-regional transport. Two-thirds of respondents (67%) cited a car as the most common mode of transportation, 40% said they walk, and 25% use buses. Just over 10% chose a bicycle (14%) or tram (11%). The least preferred mode of transportation was the train (7%). The three most frequently cited features of transportation services that respondents considered most important included easy ticket purchasing, ticket prices, and cost of travel. The aim of this paper is to discuss the decisions of Polish passengers using public transport during the COVID-19 pandemic. The results of the research may help to influence the passengers' purchasing decisions in accordance with the objectives of long-term transport policy of both the European Union and Poland related to sustainable transport development, as well as the decisions of transport operators as this is a stakeholder group that may be interested in applying them in their daily work and carriers themselves, competing for passengers.

This paper investigates the impact of implementing single and multi-optimisation solutions on the biological treatment process in a sequencing batch reactor (SBR). The research is based on a case study of the water resource recovery facility (WRRF) in Swarzewo, Northern Poland. The paper introduces the adaptive extremum seeking control (ESC) method for dissolved oxygen (DO) concentration control and places it in a layered control structure. Further, it presents the introduction of an optimisation layer for the structure and parameters of the SBR cycle, through the synthesis of stochastic methods: single-objective optimisation (SOO) using a genetic algorithm (GA) and multi-objective optimisation (MOO) using the NSGA-II algorithm. The results were compared to a classical approach with fixed cycle parameters. The paper shows the advantages of optimising cycle parameters, including the number of phases as well as the DO value, on the process flow. These control structures underwent simulation tests in the MATLAB environment with the Simba package. The biochemical processes occurring in the reactor are based on the Activated Sludge Model No. 2d (ASM2d). The optimising control system demonstrates tangible improvements in operational efficiency and significant reductions in electrical energy consumption, highlighting the effectiveness of the proposed methodologies. © 2017 Elsevier Inc.

The COVID-19 pandemic has reinforced an interest in the relationship between air pollution and respiratory viral infections, indicating that their burden can be increased under poor air quality. This paper reviews the pathways through which air pollutants can enhance susceptibility to such infections and aggravate their clinical course and outcome. It also summarizes the research exploring the links between various viral infections and exposure to solid and gaseous pollution in Poland, a region characterized by poor air quality, especially during a heating season. The majority of studies focused on concentrations of particulate matter (PM; 86.7%); the other pollutants, i.e., BaP, benzene, CO, NO x , O 3 , and SO 2, were studied less often and sometimes only in the context of a particular infection type. Most research concerned COVID-19, showing that elevated levels of PM and NO 2 correlated with higher morbidity and mortality, while increased PM 2.5 and benzo[a]pyrene levels were related to worse clinical course and outcome in hospitalized, regardless of age and dominant SARS-CoV-2 variant. PM 10 and PM 2.5 levels were also associated with the incidence of influenza-like illness and, along with NO 2 concentrations, with a higher rate of children's hospitalizations due to lower respiratory tract RSV infections. Higher levels of air pollutants also increased hospitalization due to bronchitis (PM, NO x , and O 3) and emergency department admission due to viral croup (PM 10 , PM 2.5 , NO x , CO, and benzene). Although the conducted studies imply only correlations and have other limitations, as discussed in the present paper, it appears that improving air quality through reducing combustion processes in energy production in Poland should be perceived as a part of multilayered protection measures against respiratory viral infections, decreasing the healthcare costs of COVID-19, lower tract RSV infections, influenza, and other respiratory viral diseases prevalent between autumn and early spring, in addition to other health and climate benefits. [Display omitted] • Polluted air may increase the severity of respiratory viral infections. • Poland is a PM and BaP pollution hot spot in Europe. • Air pollution is associated with a higher burden of respiratory viral infections. • Improving the air quality should be a protection measure against infections. • Further studies are encouraged to explore the relationships with other pathogens.

For the past decade, Industry 4.0 has become the basis for building competitive advantage for business operations. The key technologies of Industry 4.0 are implemented in enterprises of various industries. This paper focuses on presenting the results of research on the influence of the Industry 4.0 concept on the operations of enterprises that are implementing smart manufacturing (SM) projects. The paper analyses the following areas of influence of projects on the enterprises' operations: productivity, agility and speed, quality, competitiveness and enterprise value, profitability, staff reduction, delivery improvements, vertical and horizontal integration, resource savings, reduction of operating costs, technology adaptability and quality of machine operations. The paper belongs to the research paper category. The research tool was a questionnaire. The research was carried out in the segment of steel enterprises in Poland. The results of the presented research belong to pilot research of a segment of steel industry in Poland. The main conclusion of the study is that implementation of Industry 4.0 in the Polish steel sector had a positive influence on many factors strictly connected with the innovativeness of the company. Especially, the implementation of this conception in the steel sector leads to an increase in the quality of the product and the possibility to achieve a good level of customization of the product. Those factors are very important for the steel sector potential to succeed on the competitive market. The individual SM projects that were evaluated were a form of case study. The participants of the research were employees in managerial positions and operating technological installations in steel sector enterprises. In the opinion of the surveyed (79 people), depending on the type and scope of changes implemented in the company in the direction of Industry 4.0, decision-makers expect a higher quality of processes and products, the ability to meet customer requirements—the direction of the personalization of products and services, agility and flexibility of performed operations with the use of smart technology and accuracy and precision of performance higher than in the case of manual human activities.

• The paper was to present data on organ donation and transplantation from foreigners in Poland. • In Poland, the rules for collecting organs and tissues for transplantation from foreigners who died in Poland and the rules for transplanting organs to foreigners are adopted and applied. • In 2022, 640 potential deceased organ donors were reported to the Polish Transplant Coordinating Center POLTRANSPLANT, out of which 445 became effective donors (70%). Of the total number of reported potential donors, 24 (4%) were foreigners, and from 14 of them (58%), organs had been procured for transplantation. The majority of donors came from Ukraine. • In 2022, a total of 30 foreigners were registered on the National (Polish) Organ Transplant Waiting List. Most of them were Ukrainians. The aim of the work was to present data concerning organ donation from and transplantation to foreigners in Poland. Data came from registries maintained by the Polish Transplant Coordinating Center POLTRANSPLANT, consisting of the national waiting list, deceased donor registry, transplant registry, and live donor registry. In Poland, the rules for organ and tissue procurement for transplantation from foreigners who died in Poland and the rules for transplanting organs to foreigners are adopted and applied. Before the outbreak of the war in Ukraine, "cross-border" cases of donations and transplants were rather sporadic. After the outbreak of the war, due to the mass influx of Ukrainian citizens, the situation changed, and the participation of foreigners (mostly Ukrainians) in transplantation procedures increased significantly and, in 2022, accounted for the total number of events: approximately 4% in the case of donation, slightly over 1% in the case of qualifications for transplantation and almost 2% in the number of transplantations performed. Despite this increase, the number of events is not high or critical and does not affect the efficiency of organ transplantation medicine in Poland. [ABSTRACT FROM AUTHOR]

The importance of energy storage methods increases in the global energy industry. One of such methods is the production/generation of hydrogen and its further use called power-to-gas technology. Without highly efficient, reliable and cheap energy storage solutions, the energy sector, especially in Poland, may face significant problems related to climate protection and reduction of greenhouse gas emissions to the atmosphere in the nearest future. One alternative way to store and transport hydrogen is to blend small amounts of hydrogen (up to about 15%) into existing natural gas networks. When hydrogen is required, it can be separated near end-users using separation membranes. The paper presents the possibilities of using membrane technology in the process of obtaining hydrogen as fuel after its storage. The membrane separation technology can be used to separate mixtures of various gases, such as H2, O2, CO, CO2, or CH4 . The paper presents selected problems of the analysis of the hydrogen separation process from a mixture with natural gas for polymeric membranes with different separation properties. The structure of the separation system has been selected in order to obtain the appropriate purity of the separated gas. The energy consumption of the process of hydrogen separation from a mixture with natural gas was determined for such a system [ABSTRACT FROM AUTHOR]

Supplier selection is a decision of strategic nature that significantly influences a company's competitive advantage. The supplier selection criteria list has evolved over the years. Traditional criteria are: cost, quality and delivery. In manufacturing industry, those were highlighted as being the most important supplier selection criteria. The paper focuses on of the steel industry company in Poland. The evaluation sheets in this enterprise are the basis for creating a vendor ranking. However, they do not contain evaluation criteria in line with the sustainable development strategy. The discussed company requires introducing significant changes in the supplier selection criteria. Thus, the aim of this paper is to implement a method that will help in the selection of suppliers. Studied company operates in the area of ​​prefabrication of steel structures. In the paper, the AHP method is used. The results show dominant position of 3 suppliers out of 11. Moreover, the case study shows that in analyzed enterprise managers do not use the evaluation criteria that are in line with the sustainable development strategy. Thus, this area requires introducing significant changes in the supplier selection criteria in this company. [ABSTRACT FROM AUTHOR]

Connected vehicles revolutionize the automotive industry. A connected car can be defined as a new form of vehicle that combines ICT technology with automobiles. The main objective of this paper is to identify the benefits of connected vehicles within an organization. In addition, the paper discusses in-vehicle data, which can be used in management information systems to boost their effectiveness and new business models, such as in-vehicle payments or usage-based insurance. The research employed a questionnaire and the final sample included 161 respondents. The data were collected through the use of an online survey. The results reveal that only 42.2% of respondents declared knowledge of the connected vehicles technology. The employed respondents declared more knowledge about connected cars than those unemployed. Navigation and road traffic monitoring (mean = 4.25) were perceived by the respondents as the top benefit of connected cars. Location and condition monitoring of the vehicle (4.19) were ranked as the second top benefit. Conversely, the least potential benefits were environmental aspects (3.61) as well as access to the Internet and possibility to work while driving (3.79). The findings indicated benefits of the connected vehicles and could support managers in deploying a new technology in their organizations. The research limitation concerns the fact that this study focuses on respondents from Poland. [ABSTRACT FROM AUTHOR]

New technologies that are applied in many areas of social and economic life, make the processes of creating, distributing and communicating value to customers continuously transform. It is also connected with redefining the roles performed by market entities, including producers, service providers, distributors and consumers. New technologies expand the possibilities of engaging the consumer in processes that have been conducted before only by companies. In this context, technology management is important. It translates into creating a spiral of values, in which what is possible in the field of new technologies will inspire what is indicated in the area of value management for the customer and vice versa. This is reflected in the concept of technological determinism, as well as in the ongoing changes in consumer behaviour and consumption virtualization. The aim of the paper is to present the scope of Internet applications in the processes of managing value for customers in Poland. The paper is based on literature studies and the results of a quantitative empirical study, which was performed on a sample of 156 companies operating on the Polish market. The research included people responsible for the use of the Internet in marketing or for maintaining contacts with customers with the use of new technologies. The analysis of the research results shows that the Internet is used to a greater extent to communicate and distribute value rather than to involve customers in its creation. [ABSTRACT FROM AUTHOR]

The objective of this paper is to point out selected issues about the Total Performance Scorecard and its usefulness for Polish universities in performance measurement as well as in support in making decisions about the goals of employees and in helping them in personal develop. The carried out research, which small part is presented in this paper, indicates that current way of universities management is not really helping employees in their development as well as it does not take into account the needs of employees (specially while personal goals are set) and what's worst it can have an impact on their considerations of resignation of work. The research shows that the Total Performance Scorecard seems to be adequate for the universities. It is because this concept assumes that continuous improvement, development and learning, not only of the organization itself, but its employees as well, are very important elements of effective management of an economic unit and universities required continuous develop from their employees.

The aim of the article is to show the development of the information society in Poland through the prism of the use of e-government services in comparison to the other EU countries. At the same time, as part of the research, the aim is to indicate the strategies and methods of data security in intelligent IT systems that eliminate development barriers of the information society and e-government services. Research methodology was based on the desktop-based research that consisted of a document and database review of available information, statistics and other data from international, national, regional sources. The statistical analysis was performed on the basis of qualitative data collected from both Poland and other European Union member countries. Time frame for the research was set up for the year 2019. The analysis of the data presented in this paper shows that the demand for and willingness to use e-government services is enormous. Moreover, organizations ought to actively develop a comprehensive strategic security plan including security policy, procedures to be developed and technologies to be implemented that would integrate new applications and processes, while complying with security requirements and relevant laws and regulations. The paper also rises awareness about the importance of ensuring the protection of sensitive date in ICT and therefore limit the barriers for the development of information society, information systems (IS) and the use of Decision Support Systems (DSS) in e-government services.

The aim of the paper is to examine the issue of automated decision-making, i.e. decisions made by artificial intelligence. The use of automated decision-making is on the rise not only within private sectors, but also within the public sector. In today's world, people increasingly expect speedy decision-making, in particular in areas of public administration where to the so-called mass decisions are made pertaining to, i.a., taxation, social benefits, fees, permits, licences. Despite the fact that artificial intelligence has long been used in many areas of public administration in Poland, the automated, algorithmic decision-making process has not been regulated at the national level. The existent regulations pertain only to the serving and signing of documents. In Poland, there is a severe lack of comprehensive rules regulating automated-decision making, and at the same time, safeguarding administrative due process. The paper is based on analysis of normative acts and practice, supported by the study of secondary sources. [ABSTRACT FROM AUTHOR]

The purpose of the paper is to improve understanding of the differences and similarities between Information and Communication Technologies (ICTs) that are offered to consumers to gain their knowledge and ICTs that are expected by consumers in terms of their engagement in knowledge sharing. Thus, this paper aims to solve this problem by answering the main research question: Are the ICT offered to consumers to engage them in knowledge sharing in line with their expectations? The presented outcomes result from two sets of data, (1) a survey questionnaire on consumers and (2) a case study online observation of enterprises and public sector organizations (PSOs). Popular and well-known ICTs were taken into consideration. The findings show that both enterprises and PSOs most often offer consumers their own websites. That indicates that they choose an easily accessible and convenient tool for them to facilitate consumer engagement. The comparison of the results taken from two sets of data has revealed that consumer expectations as to ICT usage for knowledge sharing are much higher than the possibilities offered by enterprises and PSOs. This is especially true for Internet forums, industry-specialized portals, and specialized organization websites. The results also show that females would like to use ICTs in greater scope than males. It is especially true for popular information websites and Facebook portal. What is more, the results show statistically significant differences between age generations for two ICTs only, i.e., mobile applications and Facebook portal. Detailed analyses indicated that the elder generations, i.e., Baby-Boomers and Builders, would like to use these ICTs in greater scope than the younger ones. In particular, the results reveal that consumers expect to use ICTs in greater scope than those offered by enterprises and PSOs. However, the results must be interpreted with caution because of their limitations that pertain to the survey sample, which embraced consumers from Poland only, as well as to ICTs selection limited to nine items. The findings presented could be relevant to any enterprise and PSO that would like to engage consumers in providing feedback about their product and service offerings with the ICT usage.

• The paper presents critical perspective of the DFI research technique. • Presented empirical data may modify the findings formulated by other researchers of communicating about CC(U)S. • The analysed argumentation is based on presenting the innovative usage of captured CO2 as a cushion for stored natural gas. The paper presents the results of deliberative group interviews with the representatives of local communities in West Pomeranian Province (Poland) on the opportunities and challenges related to the theoretical location of combined CO 2 and natural gas underground storage (CC(U)S and UGS) in their immediate vicinity. The research has been conducted within AGaStor Project that focuses on innovative usage of captured CO 2 as a cushion for stored natural gas. Therefore, there are two possible benefits: active limitation of CO 2 emissions (Poland is and will be dependent on conventional energy sources) and reduction of gas storage costs (by using waste CO 2 as so-called cushion gas). However, previous experiences in these types of projects show the key role of local public opinion in the final shape of the investment. CC(U)S projects are usually located in less developed, less populated areas, with smaller, more rural local communities facing serious socio-economic challenges. This is the case presented in this paper. In such communities, socially expressed uncertainty and dissent are mechanisms of emancipation and articulating community's subjectivity, and a strategy for articulating fears of distrust and inadequacy of empowerment. The presented results of the research lead to four significant mechanisms of building trust for CC(U)S and UGS in West Pomeranian Province communities: a) communicating safety, b) communicating the lack of nuisances, c) communicating the benefits and d) transparent and competent knowledge transfer.

Mushrooms have become a relevant part of our diet globally, as non-animal sources of proteins; but data on their value chain and environmental impact are still scarce. Therefore, a good understanding of the environmental impacts of mushroom production, the environmental hotspots throughout the value chain, comparisons between production systems and regions, and an assessment of the improvement potential of mushroom production is required. This paper carried out a life cycle assessment (LCA) to estimate the environmental impacts of three Agaricus bisporus mushroom production systems in three different European countries: Spain, Poland and Serbia. We found that there is a large variability in the composition of the substrates, which is in all cases a combination of compost (mainly straw and animal manure) topped by casing materials (mainly peat), and a large variability in energy use, substrate use and yields. Especially the Serbian organic dried mushroom case distinguishes from the other conventional fresh mushroom cases. This is also reflected in the life cycle impact assessment results. The composting processes resulted in the largest contribution to environmental impact (about 49.6% on average ranging between 16.4% and 84.4% across all impacts assessed), followed by the electricity production and the casing (respectively 20.3% and 10.3% on average across all systems and impact categories analysed). Thus, optimizing composting and casing production together with switching to renewable energy sources appeared to be the most effective to reduce the overall environmental impacts of mushroom production. This paper provided a comprehensive assessment across Europe which could be further expanded to have a broader and more representative overview of the impact of mushroom production at European level. • A life cycle assessment (LCA) of three mushroom production systems was carried out. • Composting, casing and electricity production are the main source of impacts. • Large variability was observed in casing and compost use. • Optimising compost, casing and electricity production improves mushroom impacts. • Increasing mushroom productivity reduced mushroom production environmental impacts.

The majority of small district heating systems (DHS) in Poland are supplied with coal and do not have a status of efficient ones according to Energy Efficiency Directive. They should transform into efficient ones by taking an appropriate measures by the end of 2035. At the same time, a significant reduction of CO 2 emissions is expected in this sector. One of the possible solution for such systems is to apply unites fueled with fuels alternative to coal such as biomass. Cost benefits analysis of implementation a biomass ORC (Organic Rankine Cycle) cogeneration unit in municipal district heating system of 22 MW thermal capacity is the subject of the paper. The research included building configuration scenarios of a heat source regarding ORC size and operation modes. Different economic inputs such as electricity, fuel and European Union Allowance (EUA) for CO 2 prices as well as financial support mechanisms were considered. Economic indexes (Net Present Value, Internal Rate of Return and payback times) have been derived for both Polish and German conditions. [ABSTRACT FROM AUTHOR]

• Mercury content in the waste-derived fuels varies within a very wide range. • Co-combustion of waste-derived fuels may result in exceeding the emission limits. • Mercury content of alternative fuels should be strictly controlled. • Appropriate waste management enable the production fuels with suitable Hg content. The progressive decarbonisation of industry is leading to a reduction in coal consumption and the substitution for coal with other types of fuels, including waste-derived alternative fuels. These fuels are characterised by high variation in the content of highly toxic mercury. Co-combustion with coal can cause significant emissions, exceeding mercury emission limits. Various alternative fuels (refuse-derived fuel (RDF), waste paper, textiles, plastics, film, tires and their char, and sewage sludge) were examined for mercury content. The mercury content in analysed alternative fuels ranged from 0.4 to 92.0 µg Hg/MJ, with an average of 17.7 µg Hg/MJ. The fuels with the highest mercury content were RDFs (2.0–79.3 µg Hg/MJ) and sewage sludge (42.3–92.0 µg Hg/MJ). An acceptable amount of RDF added to hard coal which would remain within the emission limits was estimated to be 9–24% of the chemical energy in the blend. For sewage sludge, this amount was estimated to be 5–13%. For brown coal, with a much higher mercury content than hard coal, co-combustion with alternative fuels has a positive effect on reducing mercury emissions. It is possible to meet the mercury emission limits with a 95% contribution of the chemical energy coming from RDF. The blending of various types of waste supported by mild pyrolysis of high-mercury waste allows alternative fuels with relatively low mercury content to be produced. Such fuels may contribute a reduction in mercury emissions from coal-fired power plants in Poland. [ABSTRACT FROM AUTHOR]

Being part of the integration grouping, Poland benefits from the geographic, cultural and cognitive proximity to the largest investors. Making reference to the vulnerability concept and the changing nature of globalisation, presenting stylised facts on foreign direct investment (FDI) and comparing FDI to other foreign capital flows – the paper aims to predict the role of foreign-owned entities (FOEs) in Poland in the process of the post-pandemic recovery. Referring to the performance of FOEs in the 2008 crisis and comparing the volatility of various foreign inflows, FDI shall be perceived as a factor stabilising Poland's economy in a current pandemic slowdown and stimulating the post-pandemic recovery. FOEs reveal a premium over the domestic entities, and therefore their activity in Poland is expected to be helpful in the post-pandemic recovery. The paper formulates recommendations to attract foreign investors to Poland at the post-pandemic time. [ABSTRACT FROM AUTHOR]

• Scholars born in global centers decide to move to Poland enticed by a specific job offers. • A personal relationship between a Western foreign-born academic and a Pole is another common scenario. • Westerners with a specific research interest in Polish culture also move to Poland. • Work in the periphery is often associated with limited career perspectives in the country of origin. • Westerners report financial and language difficulties, cultural shock, mental differences. In this article, we discuss the issue of migration of highly qualified academics who developed in the Western education system and decided to work in Poland. While the migration flows between global centres and aspiring higher education systems are increasing, the flow of academics to the peripheries remains largely under-researched. Poland is certainly not the centre of knowledge production, but its peripheral status should be further theorized. Polish universities are unable to compete with their Western counterparts. Thus, the first research question of this paper is: Why do scholars educated in Western Europe and Northern America decide to work in the peripheries? The second one is, how do they adapt to the working conditions that are significantly different from what they were used to? This paper presents the results of nationwide research carried out among foreign-born academics working at Polish universities. The interviews (in-depth biographically-focused interviews) concerned their motivation to move to Poland, their career paths, research productivity, the perception of Poland as a place to live, future plans, among other topics. The overarching framework for this paper is the 'employment lifecycle' theory introduced by John Lavelle (Lavelle, 2007). [ABSTRACT FROM AUTHOR]

Recent focus on sustainability and its three pillars (economic, environmental, and social) brought new issues, especially for manufacturing companies, to be addressed. The article uses the methodology of a case study based on observation, panel expert, interviews with employees and the documentation analysis. The research had been carried out in steel processing enterprise in West Pomeranian region in Poland. The purpose of the article is twofold. Firstly, the aim is to present the company in the context of the production scheme and information flow, as well as the scheme for solving a decision problem that may increase the company's sustainable development potential. Secondly, the aim of the paper is to present the methodology of the process of selecting and assessing a range of criteria and fields of operation based on the identified sustainability criteria, which should be taken into account when deciding what type of the product to choose to improve the potential of sustainability of the company. The described methodology of this process is a scientific contribution based on literature research, observation of the company under study, interviews with employees, analysis of documents and work with experts inside the company, which allowed the creation of a tool for determining operational and decision-making areas that are directly related to the company's sustainable development potential.

The objective of the paper is to assess the state and changes of innovativeness of Poland in 2011–2022. According to the study, innovation in Poland still remained low, although it was slightly improving. The results of this study can be used as an instrument in setting the direction of the country's innovation policy to support the increase of its innovativeness. Knowing the innovation strengths of the Polish economy, such as trademark protection and human capital, allows for their further strengthening. In turn, the identification of weaknesses and barriers to innovation growth (including significant underinvestment in research and innovation activities, little cooperation between R&D and business, and an unfavourable climate for innovation) allows them to be reduced and transformed from barriers into growth drivers, resulting in a significant improvement in Poland's innovativeness, the consequence of which will be closing the gap dividing it from the EU average.

The paper aimed to investigate the relationship between subjective quality of life (QoL) measured by life satisfaction and two domains: material and non-material. Additionally, the aim is also to compare the effect of these two dimensions on subjective QoL among females and males. The study was conducted based on a representative sample of adult inhabitants of Poland (N=1067) in December 2021. The question regarding the quality of life consists of eight items that were focused on the following aspects of quality of life: work, level of living, income, family life, work-life balance, health, access to infrastructure (sports, cultural), and access to healthcare. These items encompass two dimensions of quality of life: material (level of living, income) and non-material (the other items). Confirmatory factor analysis and structural equation modeling analysis were used in the study. The data do not follow the normal distribution. Therefore, the estimation method was WLSMV (robust weighted least squares). Based on confirmatory factor analysis, it can be stated that two constructs (dimensions: material and non-material) are correlated at an acceptable level. Eight manifested variables are valid and the two constructs are reliable. Structural equation models in the pooled sample and based on gender are at an acceptable level according to the majority of fit indices. Two dimensions – material and non-material – affect positively subjective QoL and are statistically significant. The strength of the influence of two dimensions on subjective QoL is very similar but there are significant differences among women (higher effect of material dimension) and men (higher effect of non-material dimension).

Changes in the healthcare system are triggered by, among other things, technological developments. As such, have a correlative effect on changes in the approach to task performance of healthcare professionals. One of the other reasons for changes affecting individuals among health care personnel is also the sense of transformation of the roles undertaken by them from classically accepted to being oriented by current needs and situations. This paper presents the results of a study related to such situation in the Polish healthcare system based on quantitative results of questionnaire survey distributed to staff at selected healthcare facilities countrywide.

The experience of highly developed countries proves that innovation is the driving force of economy. Emerging economies should in particular be focused on innovation, in order to achieve higher productivity and boost their competitive advantage. This is especially important in the current reality of disruptive changes related to IT and ICT new technologies rapid emergence. Technologies already partly adopted on the ground of industrial automation lead to further implementations in many sectors of economy. The reality is often adverse. This particularly concerns insufficient activities of enterprises with respect to intellectual assets creation. Although some progress is observed, emerging economies enterprises rather applicate existing solutions, than invest in their own intellectual assets. Furthermore, financial performance measures concerning innovation activity of enterprises often provide mixed findings. In this context, the purpose of this paper was threefold: to propose a practical set of adjusted performance measures, to verify if innovators sustain performance development and receive additional economic profits, and finally to encourage stronger innovation engagement of managers and entrepreneurs. The results of this empirical study proved that the selected group of enterprises generated positive performance development within three perspectives: financial, economic and intellectual capital efficiency. Moreover, these enterprises seem to have additional innovation bias revealed by further investments of retained profits in new implementations, which should also be taken into consideration with respect to performance measures.

The paper concerns the role of e-leadership in organizations operating in crisis caused by COVID-19 pandemic. Based on the extensive literature review, it introduces a new model of organizational performance based on e-leadership, as a response for sudden growth of dependence of modern organizations on IT. The influence of e-leadership on organizational performance is assumed to be mediated by work engagement, employees' dynamic capabilities, work motivation, P-J fit and job performance. The theoretical model is verified by empirical research performed among 1160 organizations operating in Poland, Italy and USA during an active wave of COVID-19 pandemic. The obtained results confirmed the proposed hypotheses, allowing to conclude that e-leadership activates work engagement of employees, who are more willing to use their dynamic capabilities to shape work motivation and reestablish P-J fit, which in turn influences positively job and organizational performance.
