Published: August 2024

This paper aims to assess the asymmetric effect of these exchange rate variations on Brazilian sector exports to the United States, from 1999 to 2020. We assess these impacts by observing the technological intensity of the sectors analyzed. This study has applied the Non-linear Autoregressive Distributed Lag (NARDL) model to 700 sectors of the Brazilian economy. The results show that there was a long-term relationship between exports from certain sectors, foreign income, and the exchange rate. Furthermore, we observe that exchange rate variations have an asymmetric effect on exports, which can be positive or negative, depending on the sector.
Cancer genetics and deep learning applications for diagnosis, prognosis, and categorization

Published: August 2024

Gene expression data are used to discover meaningful hidden information in gene datasets. Cancer and other disorders may be diagnosed based on differences in gene expression profiles, and this information can be gleaned by gene sequencing. Thanks to the tremendous power of artificial intelligence (AI), healthcare has become a significant user of deep learning (DL) for predicting cancer diseases and categorizing gene expression. Gene expression Microarrays have been proved effective in predicting cancer diseases and categorizing gene expression. Gene expression datasets contain only limited samples, but the features of cancer are diverse and complex. To overcome their dimensionality, gene expression datasets must be enhanced. By learning and analyzing features of input data, it is possible to extract features, as multidimensional arrays, from the data. Synthetic samples are needed to strengthen the range of information. DL strategies may be used when gene expression data are used to diagnose and classify cancer diseases.

Mikrobna obremenitev morske vode in peska na plaži med kopalno sezono
Authors: Čremožnik Zupančič Jerneja , Novak Babič Monika
Published: August 2024

Slovenija je ena od najbolj vodnatih evropskih držav, kjer je voda pomembna ne le za pitje, ampak tudi za različne rekreacijske dejavnosti, še posebej plavanje. Naravne rekreacijske morske vode so pomembno okolje, v katerem so kopalci izpostavljeni bakterijam, ki so odporne proti protimikrobnim učinkovinam ter številnim vrstam gliv. Poleg morske vode ljudje veliko časa preživijo tudi na obmorskih površinah (plaža s peskom) za katere se ne izvaja mikrobiološki monitoring. Da bi določili mikrobiološko obremenitev morske vode in peska na plaži, smo tekom kopalne sezone analizirali prisotnost bakterije Escherichia coli in oportuno patogenih gliv, ki se prenašajo preko človeka. E. coli je bila prisotna le v morski vodi znotraj dovoljenih meja čez celo kopalno sezono, z največjo frekvenco v avgustu. Poleg okoljskih sevov smo zaznali tudi seve iz skupine B2, seve s povečano zmožnostjo adhezije in sistemov za privzem železa ter seve z geni za odpornost proti antibiotikom iz skupin fluorokinolonov in beta-laktamov. Gliv v vodi tekom kopalne sezone z uporabljeno metodo nismo osamili. V nasprotju pa smo v pesku na plaži zasledili glive Candida parapsilosis, Geotrichum candidum in Trichosporon asahii, ki so del kožne mikrobiote ljudi. Število E. coli v morski vodi in gliv v pesku je naraščalo s številom kopalcev in je doseglo vrh v avgustovskem vzorcu. Glede na dobljene rezultate je E. coliprimeren parameter za spremljanje kakovosti morske vode medtem ko bi za spremljanje kakovosti peska na plaži lahko kot dodatni parameter uporabljali določene vrste gliv antropogenega izvora.

Desetletja je veljalo, da osrednji evolucijski proces v slovenščini poimenujemo s tujko naravna selekcija in z domačim imenom naravni izbor. Z novim prevodom Darwinove knjige »O nastanku vrst« leta 2009 je prevajalec vpeljal nov izraz, naravno odbiranje, ki naj bi kot ustreznejši zamenjal prejšnja dva. Od takrat so v rabi različna imena, izpeljanke in kombinacije imen. Premalo prodorna priporočila stroke so večinoma ostala spregledana. Predvsem v šolstvu je zavladala negotovost glede pomena in ustreznosti različnih imen. V prispevku sta skupaj z argumenti podana predloga za enotno poimenovanje tega evolucijskega procesa z domačim imenom naravno izbiranje in s tujko naravna selekcija.
The importance of multigeneration host specificity testing: rejection of a potential biocontrol agent of Nymphaea mexicana (Nymphaeaceae) in South Africa
Authors: Reid Megan K. , Coetzee Julie A. , Gettys Lyn A. , Hill Martin P.
Published: August 2024

Classical biological control utilizes natural enemies of invasive non-native plants imported from their native range to manage problematic populations. However, a potential biological control agent must undergo strict host specificity tests to ensure that it does not feed on species native to the invaded range. Nymphaea mexicana Zucc. (Nymphaeaceae) is an invasive waterlily in South Africa that is native to the southern USA and parts of Mexico and is a target for biological control in South Africa. The planthopper, Megamelus toddi Beamer (Hemiptera: Delphacidae), is a potential biological control agent that was imported from Florida, USA for host specificity tests under quarantine conditions. Survival and multigeneration trials were carried out to determine the ability of M. toddi to survive and reproduce on its original host, N. mexicana, as well as Nymphaea nouchali Bur. fil., a waterlily native to South Africa, and Nymphaea marliacea var. chromatella Lat.-Marl., a hybrid of N. mexicana. M. toddi was unable to survive for more than two generations on the hybrid but completed three generations on N. nouchali and N. mexicana, indicating that M. toddi is unsafe for use as a biological control agent in South Africa. Nevertheless, the results from this study contribute information about a species that has not been thoroughly studied and emphasizes the importance of conducting thorough host specificity tests before releasing potential biological control agents.

Spittlebugs are pests that affect forage plants in tropical America, causing damage to such plants and causing significant annual losses in milk and meat production. One of the alternatives for combating these insect pests with minimal environmental impacts is the use of entomopathogenic fungi. The objectives of this research were: (i) to evaluate the endophytic potential of entomopathogenic fungi applied to Urochloa ruziziensis (R.Germ. & C.M.Evrard) Crins (synonymous with Brachiaria ruziziensis; Poaceae) through seed treatment for the control of the spittlebug species, Mahanarva spectabilis (Distant) and Deois schach (F.) (Hemiptera: Cercopidae); (ii) to analyze the efficiency of banker plants as a means of spreading the fungi to the field; and (iii) to determine the frequency of infection after the storage of treated seeds. U. ruziziensis seeds were treated with a suspension containing 1 × 108 conidia of the fungi Fusarium sp. (Hypocreales: Nectriaceae), Metarhizium anisopliae (Metschn.) Sorokīn (Hypocreales: Clavicipitaceae) or a commercial strain of M. anisopliae for 30 min, after which they were planted in 2 L planters and kept in a greenhouse. The surplus of treated seeds was conditioned at 22 °C and sown monthly for 10 months. Insects were fed plants from treated seeds. The entomopathogenic fungi were found to be endophytic and to equally infect the two species of spittlebugs from pastures, M. spectabilis and D. schach, at different stages of development; however, they caused low nymphal mortality. The banker plant technique with plants from seeds treated with entomopathogenic fungi was efficient. Furthermore, it was observed that it is possible to store seeds treated with fungi for 12 months. These results open the perspective of using entomopathogenic fungi with endophytic action as an auxiliary tool in reducing the populations of pasture spittlebugs in tropical regions.
Ground Projects and the Joy of Living
Authors: Scripter Lucas
Published: August 2024

Masahiro Morioka has introduced the concept of “the joy of life” as an element of his critique of prevailing tendencies toward comfort and the alleviation of suffering, which he calls “painless civilization.” I argue that this concept problematizes Bernard Williams’s idea of the “ground projects” that organize and imbue lives with meaning. In light of Morioka’s analysis, ground projects cannot be the exclusive or even primary carrier of meaning in life. Our various undertakings and pursuits may organize and orient life, but they do not hold a monopoly on meaning. Even in the face of destroyed ground projects, we can find joy in living. The dynamic that emerges from considering Williams’s view through the lens of Morioka’s conception of joy, I argue, points to the possibility of the existential transcendence of our reified selves.
Effects of binder paste-to-aggregate ratio and polypropylene fiber content on the performance of high-flowability steel fiber-reinforced concrete for slab/deck overlays

Published: August 2024

In many infrastructural engineering techniques, a common challenge is how to control the continuous damage caused by the cracks of concrete slab/decks overlay under environmental impaction or vehicle load. It drives the development of a high-flowability hybrid polypropylene and steel fiber-reinforced concrete (HPSFC), which has peculiarities for the overlay construction. In this aspect, an experimental study of HPSFC was carried out considering the factors, the volume ratio of binder paste to aggregates (P/A ratio) varied from 0.48 to 0.60, and the polypropylene (PP) fiber content changed from 0.45 to 1.35 kg/m3 with a hybrid steel fiber at 0.8% volume fraction. The workability of fresh mixes was evaluated by the indices of slump flowability and static segregation rate with an explanation of the rheological properties, and it was verified by a pumping test. The peculiarity of HPSFC applied for slab/decks overlay was determined using the tests including the early cracking resistance, the water penetration resistance, the bond strength to existing concrete, and the impact resistance. Meanwhile, the basic mechanical properties including cubic compression strength, flexural strength, and toughness were also measured. Results indicate that the fresh mixes met the requirement of high-flowing without segregation, although the indices varied with the influence of P/A ratio and PP fiber content. The resistances to early cracking and water penetration obviously improved by increasing the PP fiber content. The bond strength to existing concrete could be improved by increasing the PP-fiber content. The impact resistance enhanced with the increase of the P/A ratio and the PP-fiber content. The compressive strength and flexural strength presented an increased tendency with the P/A ratio, while the flexural toughness reached a peak at certain values of P/A ratio and PP fiber content. Comprehensively, for the high-flowability HPSFC designed with a water-to-binder ratio of 0.36, a fly-ash content of 30%, and a sand ratio of 52%, the optimal P/A ratio is 0.54 and the PP-fiber content is 0.90 kg/m3.
Die Wortgeschichte von fr. banqueroute, dt. Bankrott und it. bancarotta
Authors: Schweickard Wolfgang
Published: August 2024

The custom of breaking the table over which an insolvent or fraudulent money changer transacts his business, thereby making his insolvency obvious, was described in medieval times in Italy with the word field of It. rompere
(il banco) (recorded since 1392) and Medieval Latin (bancherium) rumpere (c1407). That practice was adopted also in France where it was initially referred to with the phrase (faire) banque route or (much less frequently) (faire) banque rompue (both recorded for the first time in 1455). Subsequently, the French term entered German as Bankrott (first in 1530) and somewhat later Italian as bancarotta (1561).

Published: August 2024

Brain nuclei are traditionally defined by their anatomy, activity, and expression of specific markers. The hypothalamus contains discrete neuronal populations that coordinate fundamental behavioral functions, including sleep and wakefulness, in all vertebrates. Particularly, the diverse roles of hypocretin/orexin (Hcrt)-releasing neurons suggest functional heterogeneity among Hcrt neurons. Using single-cell RNA sequencing (scRNA-seq) and high-resolution imaging of the adult male and female zebrafish hypothalamic periventricular zone, we identified 21 glutamatergic and 28 GABAergic cell types. Integration of zebrafish and mouse scRNA-seq revealed evolutionary conserved and divergent hypothalamic cell types. The expression of specific genes, includingnpvf, which encodes a sleep-regulating neuropeptide, was enriched in subsets of glutamatergic Hcrt neurons in both larval and adult zebrafish. The genetic profile, activity, and neurite processing of the neuronal subpopulation that coexpresses both Hcrt and Npvf (Hcrt+Npvf+) differ from other Hcrt neurons. These interspecies findings provide a unified annotation of hypothalamic cell types and suggest that the heterogeneity of Hcrt neurons enables multifunctionality, such as consolidation of both wake and sleep by the Hcrt- and Npvf-releasing neuronal subpopulation.
Cracking and Packing Information about the Features of Expected Rewards in the Orbitofrontal Cortex

Published: August 2024

The orbitofrontal cortex (OFC) is crucial for tracking various aspects of expected outcomes, thereby helping to guide choices and support learning. Our previous study showed that the effects of reward timing and size on the activity of single units in OFC were dissociable when these attributes were manipulated independently ( Roesch et al., 2006). However, in real-life decision-making scenarios, outcome features often change simultaneously, so here we investigated how OFC neurons in male rats integrate information about the timing and identity (flavor) of reward and respond to changes in these features, according to whether they were changed simultaneously or separately. We found that a substantial number of OFC neurons fired differentially to immediate versus delayed reward and to the different reward flavors. However, contrary to the previous study, selectivity for timing was strongly correlated with selectivity for identity. Taken together with the previous research, these results suggest that when reward features are correlated, OFC tends to “pack” them into unitary constructs, whereas when they are independent, OFC tends to “crack” them into separate constructs. Furthermore, we found that when both reward timing and flavor were changed, reward-responsive OFC neurons showed unique activity patterns preceding and during the omission of an expected reward. Interestingly, this OFC activity is similar and slightly preceded the ventral tegmental area dopamine (VTA DA) activity observed in a previous study ( Takahashi et al., 2023), consistent with the role of OFC in providing predictive information to VTA DA neurons.

Amaç: Bu çalışma, diş hekimliği fakültesi öğrencileri ile diş hekimlerinin kişilik özelliklerinin enneagram tipolojisine göre belirlenmesi, branş seçimlerine ilişkin tutumlarının değerlendirilmesi ve bireylerin kişilik tipi ile branşlaşma tercihleri arasındaki ilişkinin araştırılması amacıyla gerçekleştirilmiştir.

Gereç veYöntemler: Çalışmaya diş hekimliği fakültesinde lisans eğitimine devam eden öğrenciler ile lisans, doktora veya uzmanlık mezunu diş hekimleri katılmıştır. Katılımcılara bilgilendirilmiş gönüllü onam formu, demografik bilgi formu ve Türklerde enneagram prensiplerine göre kişilik tiplerini belirlemek amacıyla oluşturulan “Taştan Kişilik Tipleri Ölçeği’ni (TPI)” içeren form, çevrimiçi anket portalı “docs.google” aracılığıyla gönderilmiştir.

Kişilik tipini belirlemeye yönelik olarak Nesne Yönelimli Yaklaşımla Visual c# dilinde, .Net Framework 4.5 kullanılarak bir yazılım geliştirilmiştir.

Bulgular: Katılımcılar arasında en yüksek sayıda birey “ağız, diş ve çene cerrahisi” alanına ilgi duyarken, bunu “ortodonti” ve ardından “periodontoloji” alanı izlemektedir. Branşlaşma isteğine dair en az tercih edilen alan ise 42 kişi ile “endodonti” olmuştur. Erkek bireylerin daha fazla oranda “ağız, diş ve çene cerrahisini” tercih ettikleri, kadın bireylerin ise “pedodonti” branşını tercih ettikleri tespit edilmiştir. Enneagram tipolojisine göre bireylerin en yüksek oranda “mükemmeliyetçi kişilik tipine” sahip olduğu, bunu “yardımsever kişilik tipinin” izlediği ve en düşük oranda “sorgulayıcı” mizaç özelliklerine sahip olduğu görülmektedir. Araştırma verileri incelendiğinde diş hekimlerinin sahip oldukları kişilik ve mizaç özellikleri ile tercih ettikleri branşlar arasında ilişki olmadığını görülmektedir.

Sonuç: Çalışma neticesinde bireylerin kişilik tiplerinin, branşlama tercihlerini belirleyici bir etkisinin olmadığı görülmüştür.

Authors: Duman Tepe Rabia , Tufan Yücesoy Melek , Çakır Karabaş Hülya
Published: August 2024

Background: This case report aims to contribute to the understanding of oral findings and dental approaches in dystrophic epidermolysis bullosa, a rare hereditary disease.

Cases: We reported four congenital dystrophic epidermolysis bullosa cases from two separate families with clinical and radiographic findings in this case report. Erosive-cicatrized lesions were observed on the skin in all cases. Pseudosyndactyly was present in two cases. In the intraoral examination, reduction in mouth opening, obliteration of the vestibule sulcus, ankyloglossia, and many decayed teeth were observed in all cases. There was no intraoral lesion in two cases, but loss of lingual papillae. Intraoral bullae and erosive lesion formation were observed in two cases.

Conclusions: Dystrophic epidermolysis bullosa is a rare hereditary disease. Lesions are usually seen on the skin, but mucosal involvement is also common. For this reason, dentists should know the oral manifestations of this disease and the dentist's approach in detail.

RARE PARASITOSES IN OUR OPHTHALMIC PRACTICE
Authors: I. Pitakova
Published: August 2024

The term parasite is a word originating from Greek language and it means someone who feeds from others’ table. Humans are hosts to nearly 300 species of parasitic worms and over 70 species of protozoa. Tasks and goals - to make a retrospective analysis of rare cases of eye parasitoses in our practice. Materials and methods - patients were investigated for the period of 15 years in Eye Clinic „St. Nikolay“-Varna. The clinical cases noted concern eye diseases caused by Dirofilaria, Thelazia and Demodex. Results - for 15 years time, from 2008 to 2023 these has been one case of Dirofilaria of the eyelid, one case of Thelazia of the conjunctiva and Demodex-blepharitis in 6 patients. All of them had no reported travel abroad or contact with exotic animals. In Bulgaria, apart from our case with Thelasia, no similar case has been described, especially for such a small baby. In the case of demodex-blepharitis, we consider it a disadvantage that we have not referred our patients for parasitological examination more often. Conclusion - Cases in humans with parasites with ocular localization are relatively rare, but aren’t casuistry. We should search for them actively and think of differential diagnosis.
ROLE OF OXIDATIVE STRESS IN PREECLAMPSIA AND NORMOTENSIVE PREGNANCIES
Authors: D. Kostadinova-Slavova
Published: August 2024

Preeclampsia is described as a systemic illness associated with pregnancy. It is characterized by symptoms such as edema, proteinuria (the presence of excess proteins in the urine), hypertension (high blood pressure), and dysfunction. Recent research has extensively investigated the role of oxidative stress in the pathophysiology of preeclampsia. Oxidative stress refers to an imbalance between the production of reactive oxygen species and the body's ability to detoxify them or repair the resulting damage. Despite the research focus on oxidative stress, there is currently no consensus among researchers regarding the mechanisms that lead to the occurrence of preeclampsia in expectant mothers. The present review aims to advance the understanding of the underlying causes of preeclampsia by addressing the main biomarkers of oxidative stress.
In summary, preeclampsia is a complex condition associated with pregnancy, and its pathophysiology has been the subject of extensive research, particularly in connection to oxidative stress. However, the lack of agreement among researchers indicates that the exact mechanisms leading to preeclampsia in expectant mothers are still not fully understood and may vary across different studies or perspectives.
MIGRATION FLOWS AS A FACTOR, AFFECTING FOOD SECURITY
Authors: Iv. Milanov
Published: August 2024

The report explores various aspects of the influence of migration flows on food security. It begins by examining the definition and causes of migration and focuses on the origins and nature of migration flows to EU member states. The report assesses both positive and negative effects of migration on recipient countries, particularly its impact on food balance and food security. It also discusses the regulation of migration flows and risk management.
Highlighting the importance of the analysis of migration flows, the report addresses the challenges associated with managing risks related to migration and food security. It suggests effective policy measures to mitigate these risks. Notably, migration flows can contribute to population growth in certain areas, leading to increased food demand and potential strains on existing food systems.
To address these challenges, the report emphasizes the need for enhanced cooperation between countries. This involves sharing information, adopting best practices, establishing robust regulatory mechanisms, coordinating humanitarian aid, and establishing networks for swift crisis response.
The aim of the present study is to underscore the importance of understanding the interplay between migration flows and food security. It advocates for access to safe and nutritionally balanced food for the most vulnerable segments of society.

Published: August 2024

Along with climate change, or by transportation of agricultural products, such as fruits and ornamental plants, their alien insect pests have also started to appear in Hungary. Although these pest species are sometimes sparsely studied, their biology and interactions with their host plants provide key information for monitoring their spread and identifying their vulnerable points, targets for developing methods preventing their overpopulation. In this review article we have collected data on newly emerged moth species recently found in Hungary that might threaten plantations in Hungary in the near future.

Published: August 2024

The work was carried out to explore whether the anti-inflammatory effect of n-3 unsaturated fatty acids on patients with rheumatoid arthritis is related to the levels of inflammatory markers CRP and ESR. Studies on the treatment of rheumatoid arthritis with n-3 unsaturated fatty acid diet therapy and the outcome index containing CRP and/or ESR were included, and studies on the subjects suffering from other diseases affecting the outcome index were excluded. PubMed, Web of Science, EMBASE and Google Scholar were systematically searched, and all studies published from the establishment of the library to 2024 were collected. The Cochrane Bias Risk Assessment tool was used to evaluate the quality of the included studies. Data analysis was performed using Stata 16.0 software. Seven studies were included in this analysis. A total of 399 subjects were studied to explore the effect of an n-3 unsaturated fatty acid diet on rheumatoid arthritis. The results showed that there was no significant difference in CRP (Hedges's g = 0.06, 95% CI: −0.48–0.37, P = 0.79) and ESR (Hedges's g = −0.14, 95% CI: −0.61–0.33, P = 0.55) between the intervention and control groups. The results of this study showed that the anti-inflammatory effect of unsaturated fatty acids on rheumatoid arthritis was not correlated with CRP and ESR levels. Due to the small number of included studies, more high-quality studies are still needed to confirm this.
Robust energy management system for electric vehicle
Authors: Challoob Ali Falih , Bin Rahmat Nur Azzammudin , A/L Ramachandaramurthy Vigna K. , Humaidi Amjad J.
Published: August 2024

The Energy Management System (EMS) is critical for electric vehicle (EV) in order to optimize energy consumption, improve efficiency, and enhance vehicle performance. The EMS provides the optimization of energy distribution among various vehicle components, reduces energy losses and maximizes the vehicle's efficacy. The EMS reduces battery stress to prevent excessive charging and discharging cycles; thereby, decreases the necessity for premature battery replacement which, in turn, contributes to the battery's life time. The goal of this research is to develop robust control technique to maximize the use of energy storage systems, renewable energy sources and the bidirectional power flow associated with EVs. The proposed robust control approach is based on combination of flatness theory with artificial neural network. The controller is responsible for maintaining the voltage DC bus stabilized and enhancing the quality of the power fed to the EV side. The performance of controlled EMS is verified via computer simulation within MATLAB/SIMULINK environment. As compared to classical proportional-integral (PI) control, the computer results show the proposed controller (FEMS-ANN) gives higher power quality of EV, lower overshot level in the DC voltage, faster response to abnormal conditions, and less steady state error.

Published: August 2024

Abstract This article aims to examine the effects of weekend admission on in-hospital mortality for patients with acute myocardial infarction (AMI) in Brazil. Information from the Hospital Information System of the Unified Health System (SIH/SUS) of urgently admitted patients diagnosed with acute myocardial infarction (AMI) between 2008 and 2018 was used, made available through the Hospital Admission Authorization (AIH). Multivariable logistic regression models, controlling for observable patient characteristics, hospital characteristics and year and hospital-fixed effects, were used. The results were consistent with the existence of the weekend effect. For the model adjusted with the inclusion of all controls, the chance of death observed for individuals hospitalized on the weekend is 14% higher. Our results indicated that there is probably an important variation in the quality of hospital care depending on the day the patient is hospitalized. Weekend admissions were associated with in-hospital AMI mortality in Brazil. Future research should analyze the possible channels behind the weekend effect to support public policies that can effectively make healthcare equitable.

Published: August 2024

Abstract This study examined the spatial distribution and social inequalities in COVID-19 vaccine coverage among children aged 5-11 in Brazil. First and second dose vaccine coverage was calculated for all Brazilian municipalities and analyzed by geographic region and deciles based on human development index (HDI-M) and expected years of schooling at 18 years of age. Multilevel models were used to determine the variance partition coefficient, and bivariate local Moran’s I statistic was used to assess spatial association. Results showed significant differences in vaccine coverage rates among Brazilian municipalities, with lower coverage in the North and Midwest regions. Municipalities with lower HDI and expected years of schooling had consistently lower vaccine coverage rates. Bivariate clustering analysis identified extensive concentrations of municipalities in the Northern and Northeastern regions with low vaccine coverage and low human development, while some clusters of municipalities in the Southeast and South regions with low coverage were located in areas with high HDI-M. These findings highlight the persistent municipal-level inequalities in vaccine coverage among children in Brazil and the need for targeted interventions to improve vaccine access and coverage in underserved areas.

Published: August 2024

Abstract The organizational climate is related to the degree of motivation of its employees. This perception is essentially felt, it is neither seen nor touched, but it is real. This study aims to identify difficulties and potentialities related to the organizational climate of the nursing staff at a public hospital in the Federal District. Methodologically, a descriptive and exploratory study was carried out characterized by a qualitative approach. The thematic content analysis led to three interpretative dimensions: environment and working conditions; communication, interpersonal relationship and work flows; motivation to improve the work environment. The results indicate a deficit of human resources, scarcity of material resources, supplies, precarious physical structure, in addition to interpersonal relationship problems, such as the (de)valuation of professional nurses and nursing. The challenges posed to managers go beyond the technical and structural dimension, the technological complexity of equipment without maintenance, as it unfolds through the human dimension, feelings and unmet needs (of appreciation) of nursing, which needs to be cared for, valued, heard and seen in their care process.
