This study presents a comprehensive GIS-based multicriteria decision analysis (MCDA) framework for identifying prospective groundwater abstraction sites in a 9 municipality region of South-East Poland (Podkarpackie Voivodeship), covering approximately 830 km². The analysis integrated hydrogeological parameters (aquifer thickness, quality, productivity, water table depth, protection degree, recharge zones) with spatial risk factors (contamination sources, exclusion zones) and population density patterns. The MCDA approach provides a decision support tool for municipal authorities tasked with water infrastructure planning under conditions of limited baseline data. The framework demonstrates the utility of a carefully specified GIS-MCDA framework to provide such support, while highlighting the need for improved data sharing to enable full statistical validation.

The purpose of this article is to assess the impact of three major crises—the global economic and financial crisis of 2007–2009, the COVID-19 pandemic (2020), and the energy crisis induced by the war in Ukraine (2022)—on the condition of regional economies in Poland, both before and after their occurrence. These events, which may be regarded as black swan phenomena, were examined using several indicators of regional economic performance: the Herfindahl–Hirschman Index (HHI), the dynamics of Gross Domestic Product (GDP), industrial output sold, construction and assembly output, and retail sales. The study is based on Statistics Poland GUS data ranging from the first quarter of 2004 to the fourth quarter of 2024. The findings indicate that some Polish voivodeships (Since 1 May 2004, Poland has been divided into regions (NUTS I) and voivodeships (NUTS II). In this division, the region is statistical in nature, but in the presented research we refer exclusively to voivodeships, and therefore we also use the terms “region” and “NUTS II” interchangeably in this work. The interchangeable use of these terms also stems from the practice in Polish literature) (regions) experienced increases in industrial concentration over the study period. In 2009, during the global financial crisis, seven regions (Dolnośląskie, Lubuskie, Małopolskie, Mazowieckie, Opolskie, Podkarpackie, and Pomorskie) exhibited a relatively high degree of industrial diversification. Seven others (Kujawsko-Pomorskie, Lubelskie, Łódzkie, Śląskie, Świętokrzyskie, Wielkopolskie, and Zachodniopomorskie) showed moderate concentration. The two eastern regions—Warmińsko-Mazurskie (HHI = 194) and Podlaskie (HHI = 315)—had the highest concentration of industrial production in that year. By 2024, the overall pattern remained consistent: seven voivodeships displayed high concentration, eight moderate concentration, and one (Podlaskie) exceptionally high concentration. The degree of cyclical convergence across regions was generally high throughout the examined period. However, notable differences emerged under crisis conditions. Synchronization was strongest during the COVID-19 pandemic, when abrupt and unexpected shocks produced relatively similar regional responses. In contrast, the financial crisis of 2007–2009 and the energy crisis of 2022 generated more heterogeneous regional effects, resulting in lower and more varied levels of convergence. Full article

Rapeseed (Brassica napus) honey is a popular monofloral honey produced in Poland and is often suspected of pesticide-residue contamination due to the extensive use of pesticides in oilseed rape cultivation. Moreover, because of the presence of fatty acids, it can absorb hydrophobic polycyclic aromatic hydrocarbons (PAHs) that occur as environmental pollutants. Thus, the aim of the study was to assess the safety of rapeseed honey in terms of pesticide residues and PAHs contamination in relation to its functional properties, including antioxidant properties, polyphenol profile, protein content, and enzymatic activity. Local honey samples originating from Lublin (five) and Podkarpackie (five) Voivodeships were compared with five samples purchased from commercial sources. None of 58 pesticides, including carbamates, organophosphorus, organochlorines, pyrethroids, and neonicotinoids, were detected in the tested honey samples. All samples were also completely free of four major harmful PAHs legally limited in food (benzo[a]pyrene, benz[a]anthracene, chrysene, and benzo[b]fluoranthene). Among other PAH compounds, seven were detected accidentally in samples of various origins. The total phenolic content and antioxidant activity determined by DPPH^•, FRAP, and CUPRAC assays were relatively uniform among the groups studied. High-performance thin-layer chromatography (HPTLC) revealed characteristic fingerprints including kaempferol, ferulic acid, and caffeic acid, providing a specific profile that can be considered a marker of rapeseed honey authenticity and used to detect adulteration. Protein content ranged from 18 to 85 mg/100 g, remaining within the range typical for light honeys, while α-glucosidase activity was significantly reduced in commercial products, reflecting the effects of processing and storage. The study confirmed the high functional value and safety of rapeseed honey offered on the South-Eastern Poland market, which confirm the cleanliness of the bees’ habitat in terms of pesticide residues and PAHs pollution. Nevertheless, regular monitoring of pesticide residues and PAHs in honeys from agricultural areas remains advisable. Full article

Diatomite deposits in Poland are located in the Podkarpackie Voivodeship, and the only active deposit is in Jawornik Ruski. Therefore, it is a unique material. Improved rock processing methods are constantly in demand. In the research presented here, we have used research methods such as X-ray diffraction (XRD), scanning electron microscope (SEM), particle shape analysis, and appropriate sets of crushing machines. Diatomite comminution tests were carried out on test stands in different crushers (jaw crusher, hammer crusher, high-pressure roller press, ball mill) using different elementary crushing force actions: crushing, abrasion, and impact, occurring separately or in combination. The machines were tested with selected variable parameters to obtain products with a wide range of grain sizes ranging from 0 to 10 mm. The ball mill (yield 87%, system C3) and the hammer crusher with HPGR (high-pressure grinding roller) (yield 79%, system D2 + D3) have the greatest impact on diatom shell release and accumulation in the finest 0–5 μm and 5–10 μm fractions. For commercial purposes, it is important to obtain very fine fractions while keeping the shells undisturbed. Full article

Sustainable development is implemented not only at the global level, but primarily in local environments. Shaping the space of river valleys becomes particularly important in the face of climate change and growing water deficit. The article therefore addresses the issue of the social perception of water management in the context of climate change. The aim was to answer the questions: what is the social awareness of water management in the face of climate change, and what sustainable solutions are socially accepted? The research was carried out in the south-eastern part of Poland, in the Podkarpackie and Lublin voivodeships. The diagnostic survey method, an original survey form, and the CAWI technique were used. The study group analyzed the perception of global, negative megatrends, and challenges related to water retention in the context of climate change. The task was to identify respondents’ awareness of new sustainable management methods in river valleys. Due to the fact that the studied area is largely agricultural, differences in the perception of the studied items were sought, depending on the place of residence. It was assumed that inhabitants of rural areas have greater contact with nature, which may change their perception, and differences were looked for depending on the region of residence. Differences in the perceptions of the studied phenomena were also searched for, depending on the respondent’s sex. The calculations show that the place of residence (urban–rural) and the regions (Podkarpackie–Lublin voivodeships) do not differentiate the perceptions of most of the examined items. However, sex primarily affects the perception of global megatrends and the perception of climate change. The results indicate the respondents’ lack of awareness about natural forms of water retention. Respondents expected the implementation of outdated technical forms of flood protection. Expectations focused mainly on flood embankments and large dam reservoirs. There was strong belief among respondents regarding global megatrends and their impacts on social and economic life. A knowledge deficit was identified in relation to sustainable management methods in river valleys that favor water retention. Full article

(1) Background: Heart failure (HF) is not only a common cardiovascular disease with a poor prognosis. Its prevalence in developed countries equals 1–2% of the general population of adults, while in Poland HF, patients constitute 3.2% of the total population. Modern heart failure treatment should be focused not only on reducing the risk of death and the number of readmissions due to HF exacerbation but quality of life as well. Telemedicine has been suggested as a viable tool for enhancing HRQL. Therefore, we present the results of telemedical intervention in a group of HF patients and its effect on quality of life in chronic heart failure patients from a pilot study dedicated to reducing social inequalities in health through the use of telemedicine and e-health solutions. (2) Method: The project was a multicenter, open, non-controlled trial conducted by the University of Rzeszów, Poland. The data points were collected in the June 2023–December 2023 period from fourteen primary care units from five voivodeships, mostly considered social exclusion areas. A total of 52.7% of the patients recruited were Podkarpackie Voivodeship inhabitants. The result and discussion are presented based on the Chronic Heart Failure Questionnaire (CHFQ) and the EuroQol Visual Analogue Scale (EQVAS). (3) Results: During the program, a total of over 100,000 telemedicine examinations were conducted in the form of body weight measurement, heart rate, blood pressure tests, and 7-day Holter or 14-day event Holter assessment. Over the course of this study, coordinating the pilot program medical staff has ordered 570 changes in the patient’s pharmacotherapy, confirming the positive impact on quality of life in the study group. (4) Conclusions: A comprehensive telemedical intervention can contribute to an improvement in the quality of life of patients with HF beyond what was achieved with the basic standard of care in the group of HF patients from the social exclusion region. It is now unclear if the result of the basic telemedical intervention would be constant after discontinuation of the mentioned pilot program. Full article

Social inclusion is one of the important conditions for sustainable socio-economic development. However, one of the paths leading to social inclusion is to ensure a high level of accessibility of institutions for people with special needs. The study described in the present paper examined the accessibility of Polish public sector bodies based on data from government reports (comprehensive study). Accessibility is a feature that should be offered as a complementary service offered to both individuals and legal entities during epidemic emergencies and beyond. The limited accessibility of public institutions is a significant obstacle to the full well-being of the population. Indicating differences in the spatial dispersion of this phenomenon in Poland was the basis for undertaking research for this article. Three areas of accessibility were tested: physical (architectural) accessibility, digital (web) accessibility, and ICT accessibility. A synthetic measure of accessibility was constructed for the study and used to rank Polish voivodeships (provinces, NUTS 2) from highest to lowest. Clustering was used to identify similar regions. The highest- and lowest-scoring regions were the Mazowieckie voivodeship (capital city—Warsaw) and the Podkarpackie voivodeship (capital city—Rzeszów), respectively. Legal accessibility requirements are the biggest driver of further accessibility improvements for voivodeships. Full article

Non-tuberculous mycobacteria (NTM) are ubiquitous organisms, of which some, especially those of the Mycobacterium avium complex (MAC), may be opportunistic animal and human pathogens. Infection with NTM can interfere with tuberculosis (TB) diagnosis and induce zoonoses, especially in immunocompromised individuals. Diseases caused by NTM have become more readily recognized; however, they are likely still underestimated. In this study, we identified and genotyped Mycobacterium avium strains that were isolated during TB monitoring among free-living carnivorous animals from southeastern Poland. In 2011–2020, lymph node samples from 192 such animals were tested for mycobacteria. A total of 41 isolates of M. avium strains were detected with the use of IS901, IS900, IS1245, and mycobacterial interspersed repeat unit–variable number tandem repeat (MIRU-VNTR) identification. Thirty-three were identified as M. avium subsp. avium. These strains were derived from 1 beech marten (Martes foina), 1 common buzzard (Buteo buteo), 2 European badgers (Meles meles), 3 wolves (Canis lupus), and 26 red foxes (Vulpes vulpes). One strain isolated from a wolf was identified as M. avium subsp. hominissuis. The results show the widespread occurrence of MAC bacilli in the studied environment and additionally comprise new data on the molecular characteristics of M. avium subspecies carried by free-living southeastern Polish carnivores.

This study analyzes the impact of occupational burnout on the quality of life (QOL) of nurses surveyed during the SARS-CoV-2 pandemic. A total of 668 active nurses employed in public hospitals in Podkarpackie voivodeship (Poland) were surveyed. Throughout the pandemic, all wards where responders worked had a division into so-called “clean” and “dirty” zones, as well as balanced working hours. The research used the authors’ survey questionnaire Maslach Burnout Inventory (MBI) and the Polish version of the World Health Organization Quality of Life Instrument Short Form (WHOQOL-BREF). Descriptive statistics were used in the analysis of the collected material, while correlations between ordinal or quantitative variables were made using Spearman’s-rho coefficient. According to 94.0% of respondents, stress is an integral part of the nursing profession. The mean of the respondents’ MBI burnout was 50.83 +/− 9.05 pts. The respondents’ overall quality of life also averaged 65.74 +/− 13.12 pts. There were negative statistically significant correlations between the MBI and BREF domains, most of which were characterized by clear strengths of association. Higher exhaustion in various occupational aspects is associated with poorer quality of life in individual domains. Full article

Intense global urbanization, including spatial planning development, is an essential area that determines sustainable development. It is known that urban development is typically tied to an increase in socioeconomic productivity while also creating considerable inequalities. Despite mounting evidence of intense urban area development, little is known about its consequences on the sustainable development of territories adjacent to said areas. Despite the positive and negative consequences of urbanization and their impact on sustainable development often being highlighted, there is little understanding of and a dearth of analyses on sustainability processes that include spatial planning development. To fill this gap, it must be assessed where sustainable development is actually taking place. Such analyses should not only be confined to the four essential areas: economic development, social development, environmental development, and institutional development, that are tied to sustainable development index calculations. They should also determine the transformations experienced by the areas and factor in a fifth analysis area: spatial planning development. In this paper, detailed data sourced from the Statistics Poland were used to formulate sustainable development indices for urban, rural–urban, and rural communes of the Podkarpackie region of Poland. The data concerned the five areas listed above. Using data standardization and the averaged index method, sustainable development index values were quantified to demonstrate that they displayed various levels of inequalities for the two reference periods of 2015 and 2020. These statistics indicate the key role of spatial planning development in assessing sustainability indices. The findings show that it is not only possible to enhance standard calculation methods to include other data and use them in time and space to create a simple and general quantitative rating of sustainable development, but urbanization can also be factored in that includes spatial planning development. The findings show that a modified computation approach is a reliable and relatively complete index of sustainable development that compensates for the deficiencies of current metrics. Full article

An efficient health care system combines maximum accessibility with high-quality treatments, as well as cost optimization of individual health care facilities throughout the entire system. In hospitals, the critical element is the number of beds within individual wards, which generates costs and, at the same time, affects the capacity to serve patients. The aim of this article is to discuss the restructuring and optimization of hospital bed occupancy in a healthcare facility in the Podkarpackie voivodeship. The analysis covers the years 1999–2018. In the indicated period, the analyzed healthcare institution restructured the number of beds based on a forecast of the demand for services, which resulted in positive cost effects, without limiting patients’ access to diagnostic and therapeutic care. The analyzed facility took part in a common trend of optimizing cost-effectiveness and efficiency of hospital operations in Poland. Full article

In Poland, domestic hot water is heated mainly using fossil fuel energy sources. Such an approach results in the depletion of natural resources, pollution of the atmosphere and, consequently, irreversible changes to the climate. In response to this problem, this research identified the factors that most determine energy savings for heating water in residential buildings, as well as those that affect the choice of an alternative energy source. Additionally, the possibility of implementing shower heat exchangers in existing and newly built residential buildings was assessed, as well as society’s willingness to use such devices. The research was carried out on a sample of 462 inhabitants of the Podkarpackie Voivodeship (Poland). A questionnaire survey was used as a tool. The conducted research has shown that the perspective of environmental protection is not a sufficient motivator to save energy for heating domestic hot water. It is necessary to implement appropriate programs aimed at informing the public about the possibilities offered by the use of alternative energy sources and co-financing the purchase of appropriate devices. In the case of drain water heat recovery systems, a significant problem is also the need to develop new, highly effective designs of shower heat exchangers which can be installed under the floor linear shower drain or on the horizontal shower waste pipe.

This publication presents the methodological aspects of designing of a scoring model for an early prediction of bankruptcy by using ensemble classifiers. The main goal of the research was to develop a scoring model (with good classification properties) that can be applied in practice to assess the risk of bankruptcy of enterprises in various sectors. For the data sample, which included 1739 Polish businesses (of which 865 were bankrupt and 875 had no risk of bankruptcy), a genetic algorithm was applied to select the optimum set of 19 bankruptcy indicators, on the basis of which the classification accuracy of a number of ensemble classifier model variants (boosting, bagging and stacking) was estimated and verified. The classification effectiveness of ensemble models was compared with eight classical individual models which made use of single classifiers. A GBM-based ensemble classifier model offering superior classification capabilities was used in practice to design a scoring model, which was applied in comparative evaluation and bankruptcy risk analysis for businesses from various sectors and of different sizes from the Podkarpackie Voivodeship in 2018 (over a time horizon of up to two years). The approach applied can also be used to assess credit risk for corporate borrowers. Full article

Surface samples (0–25 cm each) of agricultural soils were investigated in five Regions (voivodeships) of southern Poland. The mean Potentially Harmful Element (PHE) pseudototal content ranges were as follows (mg/kg): As 5.19–10.9, Cd 0.34–1.56, Co 1.92–6.70, Cr 9.05–25.7, Cu 8.74–69.4, Hg 0.001–0.08, Ni 3.93–19.9, Pb 20.3–183, Sb 0.80–1.42, Tl 0.04–0.17, and Zn 61.3–422. The PHE availability depended on pH, the organic carbon (C_org) content, and the pseudototal PHE content in soils. Exchangeable and acid soluble PHE contents (BCR_F1) determined in the Community Bureau of Reference (BCR) three-step sequential extraction procedure decreased in this order: Cd > Zn > Co > Ni = Sb > Cu > Tl > As > Cr = Pb. Actually available PHE contents in pore water (0.01 mol/dm³ CaCl₂) ranged as follows: Cd 0.81–17%, Cr 0–0.25%, Cu 0.01–2.31%, Ni 0.16–2%, Pb 0.2–0.49%, and Zn 0.25–2.12%. The potential soluble total content of PHEs in pore water (0.05 mol/dm³ Na₂EDTA) ranged as follows: Cd 27–91%, Cr 0.7–7.1%, Cu 6.7–98%, Ni 3.6–41%, Pb 15–41%, and Zn 3–34%. The mobility factor (MF) values indicated Cd (31.6%) and Zn (21.0%) as the most mobile elements in soil. Other PHEs followed the order of Co > Ni > Tl > As > Sb > Cu > Cr > Pb, with the MF values <10%. The risk assessment code (RAC) values revealed a very high ecological risk of Cd and Zn in the Podkarpackie Region and a high ecological risk of Cd in the Regions of Opolskie, Śląskie, Małopolskie, and Podkarpackie, and the same of Zn in the Opolskie and Śląskie. The modified risk assessment code (mRAC) index pointed a very high potential of adverse effects in soils in the Podkarpackie and a medium potential in the Opolskie, Śląskie, Małopolskie, and Świętokrzyskie. The potential adverse effect risk, described by the individual contamination factor (ICF) factor, was the following in the Regions, in the decreasing order: Cd > Pb > Sb > Zn > Co > Cu > Ni > Tl > As > Cr, and the same as described by the global contamination factor (GCF) values: Opolskie > Podkarpackie > Świętokrzyskie > Śląskie > Małopolskie.
