Objetivo: descrever o primeiro concurso de vestibular unificado em relação as carreiras biomédicas; analisar os desdobramentos do primeiro concurso de vestibular unificado para a identidade profissional da enfermagem. Método: estudo histórico-social, descritivo, de abordagem qualitativa, que utilizou como fontes 22 publicações sobre o vestibular de 1971 do Jornal dos Sports. Dados foram coletados de julho a setembro de 2021 e analisados pelo referencial de identidade profissional. Resultados: o vestibular unificado permitiu a entrada de 47 homens, pela primeira vez, e 33 mulheres. Majoritariamente não-classificados para medicina, a opção destes candidatos em matricular-se na opção secundária foi uma estratégia de vinculação a uma instituição federal o que atrasou o preenchimento das vagas ociosas e suscitou 11 chamadas reclassificatórias. Conclusão: o vestibular unificado dificultou o acesso ao curso de enfermagem por candidatos convictos da escolha profissional. Admitir candidatos cuja primeira escolha era medicina propiciou a evasão do curso.

Authors: Nickalls Kelly
Published: December 2023

Emerging infections in pets are a worry for many public health professionals, with Brucella canis infection, the tapeworm Echinococcus multilocularis and heartworm Dirofilaria immitis all in the spotlight. The importation of animals is a big risk factor for these conditions, as is the travel of pets abroad with their owners.
Myasthenia gravis and the role of the veterinary nurse
Authors: Bell Samantha
Published: December 2023

Myasthenia is a syndrome of impaired neuromuscular transmission which can affect dogs and cats. There are two common forms, an autoimmune form where antibodies work against the neuromuscular junction – myasthenia gravis – and a rare, congenital form where the patient is born with an impairment at the neuromuscular junction, for example, they are born with too few acetylcholine receptors. This article focuses on myasthenia gravis. Patients with myasthenia gravis often also develop secondary pathologies such as megaoesophagus and aspiration pneumonia, requiring intensive supportive care from the veterinary team while hospitalised, owner counselling and support being paramount. This article describes the causes, diagnosis and treatment alongside nursing considerations for the myasthenia gravis patient and a brief discussion about future developments around the disease to help the veterinary nurse to be able to assist in better patient outcomes following a diagnosis of myasthenia gravis.
Nutritional management of the critical vomiting canine
Authors: Jacques Ruth
Published: December 2023

Many patients present for critical care with persistent vomiting and other gastrointestinal compromise including loss of appetite, inability to eat or tolerate feeding, and diarrhoea. Gastrointestinal compromise can be caused by inflammation, either primary (eg surgical trauma, infection) or secondary to other disease processes. Critical patients are at increased risk of malnourishment, with risk factors including malabsorption, anorexia, underlying disease and pain. The goal of nutritional support for the critically ill patient is to prevent further losses to lean tissue and provide energy and nutrients required for healing. As veterinary nurses, being equipped with the knowledge to create an appropriate nutritional plan for these patients has a huge impact.

Published: December 2023

Highlights

Hyperspectral imaging can be a tool to address animal feed safety and quality issues.

Various papers on hyperspectral imaging have emerged for grain and animal feed applications.

More studies need to be done to use this technology in the field and in commercial scale.

Abstract. The increasing need for safe and quality animal-derived food products and the limitations of slow and destructive traditional screening methods have driven the development of fast, accurate, and reliable testing methods for evaluation of animal feed safety and quality parameters. One of the methods being applied recently is near-infrared hyperspectral imaging (NIR HSI), an analytical technique that provides chemical and spatial information for the sample. It has been applied to various food and agricultural products and is gaining acceptance for commercial use in the food industry. This paper presents research progress with respect to applications of NIR HSI for safety and quality evaluation of animal feed ingredients, specifically in screening illegal adulteration and contamination of feed materials, detecting biological contamination and damage, measuring constituent concentrations and other quality properties, and evaluating feed processing parameters. Major results, multivariate analysis and hyperspectral image processing algorithms used, and limitations of the different studies being reviewed were highlighted. With its potential uses and applications on animal feed, NIR HSI is a promising breakthrough in the feed industry. Keywords: Animal feed, Feed safety, Feed quality, Hyperspectral imaging, NIR spectroscopy.

Published: December 2023

Highlights

This study employed AquaCrop model to simulate winter wheat growth in Oklahoma.

Different sowing dates and water availability at the time of sowing were investigated.

5 October was found to be the most optimum sowing date by producing overall greater wheat yields.

25% decrease in dryland crop yield was noted when soil water content at sowing was decreased from 100% to 40% of total available water.

Abstract. Dryland winter wheat is the most widely grown crop in Oklahoma, where water availability and temperature variations are the major factors affecting the yield of this crop. These effects were assessed using the AquaCrop model. Model calibration and validation were performed using field measurements collected from 11 site-years. The validated model satisfactorily simulated soil water content, maturity biomass, and yield, with overall normalized root mean square errors of 11%, 5%, and 9%, respectively. The model was then used in long-term (1994-2019) simulations of winter wheat at three locations in Oklahoma’s wheat belt under five sowing dates (15 Sept., 25 Sept., 5 Oct., 15 Oct., and 25 Oct.) and three soil water contents (SWC) of 40%, 70%, and 100% of the total available water at sowing. The highest simulated average dryland yields (6.4 to 6.6 Mg ha-1) were obtained for early to mid-October sowing dates under the largest SWC at sowing. The lowest average yields (2.67 to 4.15 Mg ha-1) belonged to earlier sowing (mid-September) under the smallest SWC at sowing. Irrigation had a positive impact on the yield of winter wheat and this impact increased for later sowing. The yield of winter wheat sowed in mid-September increased by 0.28 Mg ha-1 under irrigation when averaged for all years and sites, while late-October average yield was 0.96 Mg ha-1 higher than dryland average yield. Irrigation water productivities also increased with later sowing dates. Keywords: AquaCrop, Irrigation water productivity, Oklahoma, Soil water content.
Corporate social responsibility in relation to the economic dimension of socio-economic policy
Authors: Anisiewicz Urszula , Wołowiec Tomasz , Marczuk Marcin , Cichorzewska Marzena
Published: December 2023

Objectives

Corporate social responsibility is a concept that allows organizing economic life both at the level of the organization and at the level of the state taking into account the broader interests of the social environment of a contemporary enterprise and stimulating inclusive growth in the quality of economic relations. Entrepreneurs are aware that they are expected not only to generate profits, but also to fairly shape relations with the entire socio-economic environment. CSR can be defined as a concept through which companies voluntarily take into account social and environmental interests at the stage of strategy building, as well as relations with various stakeholder groups. Being responsible does not just mean meeting all formal and legal requirements, but in addition to increased investment in human resources, environmental protection and stakeholder relations.

Material and methods

The purpose of the article is to theoretically analyze the role and importance of corporate social responsibility in the process of creating an inclusive and integrative role for economics and business in the economy. The article shows that neo-liberal concepts focusing on profit maximization at all costs and the "invisible" hand of the market have significantly devalued.

Results

It is therefore possible to identify specific benefits of implementing corporate social responsibility principles. In the area of economic benefits, social environment and environmental.

Conclusions

Social responsibility benefits not only the company itself and its direct beneficiaries, but also the economy and the environment. Responsible selling allows to build loyalty and trust of employees, and consequently supports sustainable economic development based on social participation and equitable distribution of national income.
Perception of the financial situation of households in Poland in conditions of uncertainty
Authors: Sokół Marta , Paździor Artur , Zienkiewicz Konrad
Published: December 2023

Cel pracy

Sytuacja finansowa gospodarstw domowych jest nierozerwalnie związana z procesami zachodzącymi w ich otoczeniu. Wysoka inflacja i wynikające z niej realnie niższe dochody oraz niepewność co do przyszłości, mogą powodować zmiany w dotychczasowym funkcjonowaniu gospodarstw domowych i w dotychczasowej konsumpcji. Celem niniejszego artykułu jest analiza i ocena postrzegania swojej sytuacji finansowej przez gospodarstwa domowe w Polsce, wynikająca z niepewności związanej z wysoką inflacją.

Materiał i metody

Zastosowanie metody badawcze objęły studia literaturowe, analizę raportów GUS oraz analizę statystyczną wyników badań ankietowych skierowanych do losowo wybranej grupy 1000 respondentów. Pozwoliło to ocenić czy aktualne zdarzenia miały wpływ na zmianę subiektywnej oceny gospodarstw domowych dotyczącej ich sytuacji finansowej. Postawione hipotezy zweryfikowano przy zastosowaniu testu niezależności χ^2.

Wyniki

Z przeprowadzanych w lutym 2023 roku badań wynika, że większość gospodarstw domowych ocenia swoją sytuację finansową gorzej niż rok temu, a niemal połowa przewiduje, że w najbliższym czasie pogorszy się ona jeszcze bardziej. Ocena bieżącej sytuacji finansowej oraz kierunek jej zmiany nie są jednak zależne od płci, wieku, wykształcenia czy miejsca zamieszkania respondenta. Z kolei przewidywania co do przyszłej sytuacji finansowej są zależne od oceny sytuacji obecnej.

Wnioski

Na podstawie przeprowadzanych badań można ocenić, że w wyniku niepewności wywołanej inflacją nastroje wśród respondentów były pesymistyczne.
Tax economics and tax policy and the market reactions of taxpayers
Authors: Wojciechowski Łukasz , Skrzypek-Ahmed Sylwia , Wołowiec Tomasz , Bogacki Sylwester , Paklerska Alina , Ociesa Kinga
Published: December 2023

Objectives

In a market economy, allocation decisions are more or less visibly related to the monetary savings of entities. The tendency of entities to save depends on both the interest rate on deposits and inflation, as well as the tax rate on income from capital (monetary savings). Also, the willingness of business entities to invest depends on the income from invested capital. Tax policy, its nature, implemented solutions, instruments in the form of reliefs and exemptions, and, above all, stability and predictability are an important element of effectively influencing taxpayers' behavior.

Material and methods

Induction was used as the main research method. It involves drawing general conclusions or establishing regularities based on the analysis of empirically identified phenomena and processes. Moreover, the work uses two general research methods, i.e. analytical and synthetic methods, characterized by a specific approach to the study of reality.

Results

To ensure economic growth and development, it is necessary to develop favorable tax solutions. Taxes should not affect the taxpayer's assets to an extent that prevents their further development. Therefore, it is important to balance the amount of tax collected from the company.

Conclusions

A simple consequence of the fiscal function of income taxes is a direct impact on the allocation of resources in the economy, because when the tax is paid, there is a final flow of income between the taxpayer and the state. The fiscal function of income taxes is always related to the allocation of resources, as it reduces the incomes of households and businesses, which limits their ability to invest, consume and save.
Income taxes and stability and stimulation functions of public policy
Authors: Ivashko Olena , Wojciechowski Łukasz , Życzkowski Adam , Witkowski Jacek
Published: December 2023

Abstract
The stabilisation function of the state's finances encompasses measures aimed, inter alia, at achieving and maintaining a relatively high rate of economic growth, while limiting negative phenomena, i.e. high unemployment and inflation rates, mitigating business cycle fluctuations, stabilising the money market and making the most effective use of tangible factors of production. The role of the state in the economy and its influence on the behaviour of groups of economic units has undergone dynamic changes over the centuries, both with regard to the forms and scope of influence and the degree of interference of public authorities in the market mechanism

Streszczenie
Stabilizacyjna funkcja finansów pastwa obejmuje działania mające między innymi powodować osiągnięcie i utrzymanie relatywnie wysokiego tempa wzrostu gospodarczego, przy jednoczesnym ograniczaniu zjawisk negatywnych, tj. wysokiej stopy bezrobocia i inflacji, łagodzeniu wahań cyklu koniunkturalnego, stabilizację rynku pieniężnego oraz możliwie najbardziej efektywne wykorzystanie rzeczowych czynników produkcji. Rola państwa w gospodarce i jego wpływ na zachowanie się grup jednostek gospodarujących ulegała dynamicznym zmianom na przestrzeni wieków, zarówno odniesieniu do form i zakresu oddziaływania, jak i stopnia ingerencji władz publicznych w mechanizm rynkowy.
Conformance of the Internet sales systems of Polish regional rail carriers with Regulation (EU) 2021/782 of the European Parliament and of the Council in the aspect of obligation of providing information about the minimal fares
Authors: Kowalik Przemysław
Published: December 2023

Cel pracy

Przedmiotem opracowania jest zbadanie funkcjonowania internetowych systemów sprzedaży polskich regionalnych przewoźników kolejowych w zakresie obowiązku informowania o najniższych dostępnych cenach przejazdu wynikającego z rozporządzenia Parlamentu Europejskiego i Rady (UE) 2021/782. Z powodu skomplikowanej struktury taryf stosowanych przez przewoźników mogą bowiem wystąpić przypadki, w których najtańszy przejazd na danej trasie może wymagać wykonania zakupu „niestandardowego”: zakupu więcej niż jednego biletu lub też biletu na trasę inną niż ta, która faktycznie będzie przejechana.

Materiał i metody

Zbadano strukturę taryf przewoźników oraz działanie systemów sprzedaży pod kątem obsługi wspomnianych wyżej „niestandardowych" zakupów biletów.

Wyniki

Wyniki badań pokazały, że systemy sprzedażowe większości przewoźników nie zapewniają obsługi wyżej wspomnianych „niestandardowych” zakupów poprzez automatycznie wygenerowaną ofertę. Niemniej jednak taki zakup jest technicznie możliwy, ale wyłącznie poprzez samodzielne żądanie użytkownika.

Wnioski

Jako wnioski z badań sformułowano postulaty de lege ferenda odnośnie doprecyzowania samego przepisu o obowiązku informowania o najniższych kosztach zawartego w rozporządzeniu, jak również zasad działania systemów sprzedażowych oraz tworzenia taryf przewozowych.
Optimisation models and the economics of managerial decision-making
Authors: Ćwik Kamila , Skrzypek-Ahmed Sylwia , Cwynar Wiktor , Skowron Stanisław , Mróz-Gorgoń Barbara
Published: December 2023

Making optimal decisions is a process whose aim is to select the best solution from the perspective of efficiency, economy and rationality. This process includes a group of logically related mental and computational operations. They lead to the selection of the best possible decision-making option. To optimize decision-making processes and increase their quality, various methods and techniques based on mathematics and statistics are used. Decision-making is a basic condition for solving management and economic problems in an organization, whether traditional, process-based or project-based.

Rational models, where the issue of rationality in the decision-making process is considered in relation to: conditions and assumptions that must be met in order for decisions to be classified as rational, practical recommendations (how a rational manager should act), model approaches to decision-making processes (how how decision-making processes should proceed). Behavioral models of bounded rationality. Here, the decision-maker follows the rules of full rationality, but is not "perfect" in his tasks. He is prevented from acting fully rationally by certain limitations: cognitive, motivational, organizational or emotional. Heuristic models - they assume a complete departure from full rationality, present real decision-making processes, akin to the "double process" mozel - integrate an approach oriented on rational analysis with an approach oriented on intuition
Who Accused Whom of What? The Outbreak of the "Arian" Controversy
Authors: Fernández Samuel
Published: December 2023

Abstract: This article aims to reconstruct the outbreak and initial parameters of the so-called Arian crisis. To do that, it divides ancient sources into two different groups: 1) the sources that reproduce or depend on the polemical narrative of Athanasius and 2) the documents contemporary to the events, which are quoted in ancient works. Since Athanasius's narrative is one-sided and retrospective, the article reconstructs the beginning of the controversy by giving effective priority to documents contemporary to the events over accounts coming from the bishop of Alexandria. Thus, the first part of the article studies the outbreak of the dispute according to ancient sources; therefore, it reconstructs the beginning of the controversy in light of the sources coming from Athanasius, analyzes the chronology of the contemporary documents, and finally reviews the outbreak of the crisis by giving hermeneutical priority to contemporary documents. The second part studies the initial theological parameters of the debate, namely, the theologies of Alexander and Arius, and the "Arian" theology according to Alexander. The last part of the article addresses the ecclesiastical dimension of the controversy, that is, the nature of "the group around Arius" and the institutional setting of the conflict. The conclusion re-examines the outbreak of the Arian crisis.

Bandwidth limitation in optoelectrical components and the chromatic dispersion-induced power fading phenomenon cause severe inter-symbol interference (ISI) in high-speed intensity modulation and direct detection (IM-DD) optical interconnects. While the equalizer implemented in the receiver's digital signal processing procedure can mitigate ISI, it also inevitably enhances the noise located in the decayed frequency region, known as equalization-enhanced colored noise (EECN). Additionally, the nonlinear impairments of the modulator and photodetector also deteriorate the performance of the IM-DD system, especially for high-order modulation formats. In this work, we propose a gradient-descent noise whitening (GD-NW) algorithm to address EECN and extend it by introducing nonlinear kernels to simultaneously mitigate EECN and nonlinear impairments. The proposed algorithms are compared with conventional counterparts in terms of the achievable baud rate and the receiver optical power sensitivity. As a proof-of-concept experiment, we validate the principles of the proposed algorithms by successfully transmitting 360-GBd on-off-keying (OOK) and 180-GBd 4-level pulse-amplitude-modulation (PAM-4) signals in the back-to-back case under a 62-GHz brick-wall bandwidth limitation. 280-GBd OOK and 150-GBd PAM-4 transmissions are also demonstrated over 1-km standard single-mode fiber with a bit error rate below 7% hard-decision forward error correction aided by the proposed approach.

We present a tunable (6.62-11.34 µm), singly-resonant, cascade optical parametric oscillator with intracavity pumping of BaGa2GeSe6 in the second stage and spectral narrowing realized by a Volume Bragg Grating acting on the signal wave of the first stage which serves as a pump for the second stage. The maximum energy achieved near 8 µm in the narrowband regime is 1.1 mJ at 100 Hz (spectral width: ∼20 cm-1, pulse duration: ∼7 ns). The overall conversion efficiency from 1 to 8 µm for broadband and narrowband operation is 4.0% and 3.1%, respectively, corresponding to quantum efficiencies of 31% and 23%.

High power and high brightness laser lighting puts forward new requirements for phosphor converters such as high luminous efficiency, high thermal conductivity and high saturation threshold due to the severe thermal effect. The structure design of phosphor converters is proposed as what we believe to be a novel strategy for less heat production and more heat conduction. In this work, the rod-shaped YAG:Ce phosphor ceramics (PCs) and disc-shaped YAG:Ce PCs as control group were fabricated by the gel casting and vacuum sintering, to comparatively study the luminescence performance for LD lighting, on the premise that the total number of transverse Ce3+ ions and the volume of samples from two comparison groups were same. All rod YAG:Ce PCs with low Ce3+ concentration exhibited the high luminous efficiency and better thermal stability than YAG:Ce discs with high Ce3+ concentration. Under the laser power density of 47.8 W/mm2, the luminous saturation was never observed in all rod-shaped YAG:Ce PCs. The high luminous efficacy of 245∼274 lm/W, CRI of 56.3∼59.5 and CCT of 4509∼4478 K were achieved. More importantly, due to the extremely low Ce3+ doping concentration (0.01 at%), rod-shaped ceramics based LDs devices showed the excellent thermal performance and their surface temperatures were even below 30.5 °C surprisingly under the laser power density of 20.3 W·mm-2 (2 W).

In this paper, an end-to-end methane gas detection algorithm based on transformer and multi-layer perceptron (MLP) for tunable diode laser absorption spectroscopy (TDLAS) is presented. It consists of a Transformer-based U-shaped Neural Network (TUNN) filtering algorithm and a concentration prediction network (CPN) based on MLP. This algorithm employs an end-to-end architectural design to extract information from noisy transmission spectra of methane and derive the CH4 concentrations from denoised spectra, without intermediate steps. The results demonstrate the superiority of the proposed TUNN filtering algorithm over other typically employed digital filters. For concentration prediction, the determination coefficient (R2) reached 99.7%. Even at low concentrations, R2 remained notably high, reaching up to 89%. The proposed algorithm results in a more efficient, convenient, and accurate spectral data processing for TDLAS-based gas sensors.
Noise-robust latent vector reconstruction in ptychography using deep generative models

Computational imaging is increasingly vital for a broad spectrum of applications, ranging from biological to material sciences. This includes applications where the object is known and sufficiently sparse, allowing it to be described with a reduced number of parameters. When no explicit parameterization is available, a deep generative model can be trained to represent an object in a low-dimensional latent space. In this paper, we harness this dimensionality reduction capability of autoencoders to search for the object solution within the latent space rather than the object space. We demonstrate what we believe to be a novel approach to ptychographic image reconstruction by integrating a deep generative model obtained from a pre-trained autoencoder within an automatic differentiation ptychography (ADP) framework. This approach enables the retrieval of objects from highly ill-posed diffraction patterns, offering an effective method for noise-robust latent vector reconstruction in ptychography. Moreover, the mapping into a low-dimensional latent space allows us to visualize the optimization landscape, which provides insight into the convexity and convergence behavior of the inverse problem. With this work, we aim to facilitate new applications for sparse computational imaging such as when low radiation doses or rapid reconstructions are essential.

Linkage disequilibrium (LD) is a fundamental concept in genetics; critical for studying genetic associations and molecular evolution. However, LD measurements are only reliable for common genetic variants, leaving low-frequency variants unanalyzed. In this work, we introduce cumulative LD (cLD), a stable statistic that captures the rare-variant LD between genetic regions, which reflects more biological interactions between variants, in addition to lack of recombination. We derived the theoretical variance of cLD using delta methods to demonstrate its higher stability than LD for rare variants. This property is also verified by bootstrapped simulations using real data. In application, we find cLD reveals an increased genetic association between genes in 3D chromatin interactions, a phenomenon recently reported negatively by calculating standard LD between common variants. Additionally, we show that cLD is higher between gene pairs reported in interaction databases, identifies unreported protein-protein interactions, and reveals interacting genes distinguishing case/control samples in association studies.
Political participation and the social media network of young Nigerians
Authors: Egbunike Nwachukwu Andrew
Published: December 2023

Social media have expanded the opportunities for a more inclusive youth political participation (YPP) across the world. Previous studies on YPP have focused on how social media have influenced participation in elections, with scant attention given to the impact of the networked capacity of online political discourse on offline youth political participation. The generative capacity of Benkler’s Networked Public Square served as the framework, while mixed methods of QUAN + qual triangulation design was employed. The Lagos metropolis was stratified into Mainland and Island, with 505 copies of a questionnaire purposively administered to digitally competent Nigerian youth across the areas. In-depth interviews were conducted with twelve young political social media influencers. Results were thematically analysed, expressed in frequency counts and/or correlation analysis at p ≤ 0.05. The positive and significant relationship between Twitter use and offline YPP (r = 0.1) has great conceptual implications on the generative capacity of the networked public sphere.

The rectified channel was installed in the Itajaí-Mirim river in the mid-1960s to increase the river flow in the urban area of Itajaí, which suffers from flooding and inundation during periods of high precipitation. The present study aimed to evaluate the spatio-temporal variations of the benthic macrofauna of the Itajaí-Mirim river, in the original and rectified channels. The distribution of organisms was evaluated with samples collected at four points, two located in the natural channel and two in the rectified channel, during the four seasons of 2021. At each sampling point, with a van Veen dredge, three samples were collected for macrofauna and one for granulometric characterization. In total, 715 individuals were identified, and distributed in eight taxa. PERMANOVA revealed that the differences observed in the abundance of organisms considering seasonality were not significant, however, they were significant between the channels. The rectified channel exhibited 67% of the total abundance of the analyzed fauna. In this region, the organic matter and CaCO3 exhibited the highest concentrations and the sediment was classified as silt, while in the natural channel, the granulometry varied between fine sand and silt. The oligochaete Tubificida was the most abundant organism, representing 97% of the fauna. Considered tolerant, this organism inhabits freshwater sediments with low oxygen concentration and high organic carbon load. The low richness of the community and the high dominance of Tubificida characterized the evaluated region as a highly altered environment.

Published: December 2023

O artigo em tela é uma tentativa de desenvolver uma abordagem na seara das Tecnologias Sociais tendo como base empírica à tecnologia financeira do Agroamigo, isso como estratégia na oferta de serviços financeiros destinado aos agricultores familiares mais pobres do Nordeste. A instituição financeira responsável, o Banco do Nordeste do Brasil, criou a metodologia justamente para superar a alta, com sucesso em seus resultados, mas que também trouxe internamente contradições como a monotonia na aplicação desse modelo de microfinança rural, bem como na questão da limitação dos recursos concedidos e da ausência de articulação de políticas públicas, para concretamente cumprir seus preceitos estratégicos. O interesse é justamente analisar até que ponto o verniz das Tecnologias Sociais tem importância na construção ou aperfeiçoamento da tecnologia do Agroamigo, em especial no seu papel de operar sob o lastro da valoração do menor custo operacional e principalmente em trazer benefícios socioeconômicos aos agricultores familiares mais pobres do Nordeste.

O acesso à água doce é premissa para o desenvolvimento econômico, social e ambiental, reconhecido como um direito fundamental pelas Nações Unidas em 2010. No entanto, o crescimento industrial, populacional e as mudanças climáticas estão causando escassez de água, com previsões de afetar bilhões de pessoas até 2050. Para garantir a segurança hídrica, soluções alternativas, como a captação de água da chuva, estão ganhando destaque, especialmente em áreas urbanas. Este estudo avaliou os impactos da captação de água da chuva para usos não potáveis na Escola Municipal Cordeiro Filho, em Lagoa dos Gatos - PE, uma região suscetível a crises hídricas. Usando métodos de pesquisa de campo, foram coletadas informações sobre a demanda de água para descargas e limpeza. Os resultados mostraram que um reservatório de 80 m³ atenderia completamente a essa demanda, reduzindo o consumo de água da concessionária em 66,17%, gerando economia anual de R$ 13.381,85. O custo de implantação do sistema foi de R$ 118.808,67, com retorno do investimento em 8,9 anos. Esse estudo demonstra que a captação de água da chuva é uma solução viável para enfrentar a escassez de água, atendendo a critérios técnicos, econômicos e ambientais, contribuindo para a gestão sustentável dos recursos hídricos.
