Project-Based Learning as a Method for Interdisciplinary Adaptation to Climate Change—Reda Valley Case Study
Authors: Wróblewska Dominika , Okraszewska Romanika
Published: May 2020

The challenges of the global labour market require university authorities to extend traditional forms of education into more innovative and effective solutions. Project-based learning (PjBL) is one of highly effective methods for acquiring knowledge and teaching “soft” skills to future employees. This article describes an experimental use of PjBL at a university with a long history of teaching based on traditional methods—the Gdansk University of Technology. The experiment was conducted in the academic year 2017–2018, in collaboration with the city of Wejherowo. The project’s main goal was to solve the city’s real problems related to climate change, land development and water management. The project was implemented experimentally as part of two subjects: spatial planning, and monitoring and environmental management to ensure an interdisciplinary approach and cover the scope of the project fully. The results of the experiment confirmed the evidence-based advantages of PjBL. However, several methodological, organisational and technical problems, which need to be resolved before a new edition starts, were encountered during the experimental implementation of the method. The experiment was positively received by students, clients, and tutors. To evaluate the impact of PjBL on spatial planning education, the new edition must include a methodological framework for evaluation.

Published: May 2020

(1) Background: New migratory flows taking place in Europe and the USA are categorised by a huge arrival of unaccompanied foreign minors (UFM), requiring appropriate attention to schooling in order to guarantee their integration. In facing this situation, the various political and educational administrations of the European Union (EU) have promoted an action plan for schools. Despite this, it has been shown that schooling does not totally guarantee social integration, encouraging the development of a new social model to generate new ways of understanding the learning process. (2) Methods: The aim of the present study is to adapt and validate Bandura’s academic self-efficacy scale (2006) within a sample of UFM. This scale is composed of 18 items distributed according to three underlying constructs. (3) Results: The validation analysis consisted of an exploratory factorial analysis using principal component analysis with varimax rotation, followed by confirmatory factorial analysis using structural equations (root mean squared error of approximation (RMSEA) = 0.052; normalised fit index (NFI) = 0.90; incremental fit index (IFI) = 0.91; confirmatory fit index (CFI) = 0.91). Reliability and internal consistency of the instrument was also tested with values being higher than 0.7 for all dimensions. (4) Conclusions: The final instrument was reduced to 12 items which were grouped into three dimensions (effort, self-confidence and understanding). Finally, the conducted multi-group analysis showed a stronger relationship between understanding, self-confidence and effort within UFM who had resided in Spain for a longer time. This could be linked to the more prolonged schooling process received.

Published: May 2020

Background: Bioelectrical impedance vector analysis (BIVA) is a body composition assessment method based on the interpretation of the raw bioimpedance parameters. While it was initially proposed in clinical settings, its use in the sports field has grown considerably. The aim of this study was: (i) to explore the role of somatotype on BIVA patterns and (ii) to propose a new target zone to improve BIVA analysis in ball games athletes. Methods: One hundred and sixty-four male volleyball, soccer, and rugby players (age 26.2 ± 4.4 yrs; body mass index (BMI) 25.4 ± 2.4 kg/m2) were included in this study. Somatotype and BIVA were measured from anthropometric and bioelectrical data, respectively. Results: Forty-six athletes were classified with an endomorphic mesomorphic somatotype, 26 showed a balanced mesomorphy, 55 were ectomorphic mesomorph, 10 resulted as mesomorph ectomorphs, 13 with a mesomorphic ectomorph somatotype, and in 14 athletes a balanced ectomorphy was assessed. The results of the Hotelling’s T2 test showed significant differences in BIVA patterns for the endomorphic mesomorph group (p < 0.001) in comparison with all the other groups, while mesomorphic balanced athletes presented a more inclined vector compared to the athletes with a balanced ectomorphy (p < 0.003). In addition, the endomorphic mesomorph group showed a greater BMI (p < 0.001) with respect to the athletes grouped in the other somatotype categories. Discriminant analysis revealed two significant functions (p < 0.001). The first discriminant function primarily represented differences based on the bioelectrical standardized resistance parameter (R/H) measure, while the second function reflected differences based on the bioelectrical standardized reactance parameter (Xc/H). Conclusions: Athletes presenting a higher endomorphic component have a lower vector, whereas those with a larger mesomorphic component display higher vector inclinations on the R-Xc graph. We propose a new target zone to improve the interpretation of BIVA analysis in athletes engaged in team sports.

Published: May 2020

The recent pandemic has raised significant challenges worldwide. In higher education, the necessity to adopt efficient strategies to sustain education during the crisis is mobilizing diverse, complementary, and integrative action in response. In this research article, we rise to the challenge of designing and implementing a transparent strategy for social media awareness at King Abdulaziz University (KAU). We introduce a framework for social media impact, termed the KAU Pandemic Framework. This includes the factors with the most important role in enhancing the deployment of social media in crisis in order to minimize the negative impact on education’s sustainability. We used a mixed-methods approach, integrating quantitative statistical analyses of social media data and online surveys and qualitative interviews in such a way as to construct a comprehensive framework. The results show that a methodological framework can be justified and that Twitter contributes significantly to six areas: administrative resilience; education sustainability; community responsibility; positive sentiment; community bonds; and delivery of promised value. The components of our proposed methodological framework integrate five pillars of the strategic adoption of social media: social media governance; social media resilience; social media utilization; decision-making capability; and institutional strategy. Finally, we show that the KAU Pandemic Framework can be used as strategic decision-making tool for the analysis of the gaps and inefficiencies in any social media plan that is deployed and the management challenges arising from the pandemic.
Joint Probabilistic Modeling of Wind Speed and Wind Direction for Wind Energy Analysis: A Case Study in Humansdorp and Noupoort
Authors: Arashi Mohammad , Nagar Priyanka , Bekker Andriette
Published: May 2020

South Africa has great potential for considering wind energy as an alternative resource. The climatology allows for significant wind energy production. An accurate joint description of the wind speed (linear) and wind direction (circular) characteristics is important for wind farm development. In this paper, a bivariate class of flexible joint probability density functions of wind speed and wind direction for the use in wind energy analysis is presented. This joint model accounts for bimodality, skewness, and a dependency structure between the wind speed and wind direction. For the joint probabilistic description of the wind speed and wind direction, special cases of this bivariate class are evaluated, namely the semi-parametric Möbius model on the disc, the Möbius distribution on the disc, and the Beta type III Möbius distribution on the disc. These three special cases are applied to wind speed and wind direction data recorded every ten minutes at two locations in South Africa. Evaluation of the models is based on three different information criteria and normalized deviation. Overall, the semi-parametric model is superior to the parametric models based on the performance measures. The wind energy potential at the two locations is evaluated using the semi-parametric model.
Enabling Relationships with Nature in Cities

Published: May 2020

Limited exposure to direct nature experiences is a worrying sign of urbanization, particularly for children. Experiencing nature during childhood shapes aspects of a personal relationship with nature, crucial for sustainable decision-making processes in adulthood. Scholars often stress the need to ‘reconnect’ urban dwellers with nature; however, few elaborate on how this can be achieved. Here, we argue that nature reconnection requires urban ecosystems, with a capacity to enable environmental learning in the cognitive, affective and psychomotor domains, i.e., learning that occurs in the head, heart and hands of individuals. Drawing on environmental psychology, urban ecology, institutional analysis and urban planning, we present a theoretical framework for Human–Nature Connection (HNC), discuss the importance of nurturing HNC for children, elaborate on the role of property-rights and the importance of creating collective action arenas in cities for the promotion of urban resilience building. As values and environmental preconceptions underly environmental behavior, there are limits to achieving HNC in cities, as presumptive sentiments toward nature not always are positive. We end by discussing the role of new digital technologies in relation to HNC, and conclude by summarizing the major points brought forward herein, offering policy recommendations for HNC as a resilience strategy that can be adopted in cities throughout the world.
Ecosystem Services, Green Infrastructure and Spatial Planning
Authors: Zoppi Corrado
Published: May 2020

Ecosystem services and green infrastructure do not appear to inform spatial policies and plans. National governments hardly identify their ecological networks or make an effort to integrate them into their spatial policies and plans. Under this perspective, an important scientific and technical issue is to focus on preserving corridors for enabling species mobility and on achieving connectivity between natural protected areas. In this respect, this Special Issue takes a step forward insofar as it aims at proposing a theoretical and methodological discussion on the definition and implementation of ecological networks that, besides guaranteeing wildlife movements, also provide a wide range of ecosystem services. The social and economic profile of this question is also relevant since in the long run, savings in public spending (e.g., due to the reduced need for grey infrastructures aiming at contrasting soil erosion or at managing flood risk), savings in private spending (e.g., on water treatment costs) and the potential creation of green jobs are foreseeable. Moreover, indirect and less easily quantifiable social and health benefits (e.g., due to improved natural pollution abatement) are likely to occur as well.
The Role of Port Development Companies in Transitioning the Port Business Ecosystem; The Case of Port of Amsterdam’s Circular Activities
Authors: de Langen Peter W. , Sornn-Friese Henrik , Hallworth James
Published: May 2020

There is a gradual but clear transition towards a circular economy (CE) that will potentially have significant impacts on ports, both in their function as transport nodes and as locations for logistics and manufacturing activities. A rough appraisal of new investments in circular manufacturing activities in ports in Europe drawn from organizational reports and official webpages illustrates the (slow) development of circular activities in ports. This paper is to our knowledge the first paper which deals with the implications of CE for the business model of the port development company. We assess if and how the circularity transition affects the role and business model of port authorities as developers of port clusters. We outline a framework for analyzing the consequences of CE on the business model of the port authority. We then apply this framework to get a detailed understanding of the emerging CE ecosystem in the Port of Amsterdam, which is clearly a frontrunner in the transition, and the role of the government-owned Port of Amsterdam port development company (PoA) in developing this ecosystem. In Amsterdam, a CE ‘business ecosystem’ has emerged and continues to evolve with three types of synergies between the companies in this ecosystem: logistics infrastructure and services synergies, input–output synergies and industrial ecology synergies. We find that the spatial scale of the CE value chains in the port varies between segments and that they are generally less international than ‘linear’ value chains. The development of CE activities occupies a central place in PoA’s strategy, and PoA assumes new and active roles in advancing the circular business ecosystem, most notably through developing industrial ecology synergies and nurturing and attracting new, innovative CE companies. Finally, the circularity transition leads to changes in PoA’s business model, with an increasing focus on new services that create synergies, and a decreasing importance of the share of port dues in the total revenue mix.
Secondary Students’ Identities in the Virtual Classroom

Published: May 2020

Though researchers have paid attention to the social aspect of students’ virtual and online learning, little attention has been paid to their identity. The present research intends to do so by studying students’ identities when learning high-level mathematics in the virtual classroom. Fourteen secondary school students participated in the research. Data were collected using interviews with the participants before and after participating in the virtual mathematics classroom. Data analysis was done using inductive and deductive content analysis, where the deductive analysis utilized the narrative framework developed by Sfard and Prusak. The research results indicated that the virtual identities of high-level mathematics students were impacted by three factors: the design of the virtual classroom, the teacher’s interactions with the student, and the personal characteristics of the student. In addition, the research results indicated that students’ identities, in terms of features and narratives, changed in the case of some students, but continued to be the same in the case of other students. The reasons behind the change or the absence of change were the three above factors and their interaction. It is concluded that the virtual course design needs to take into consideration the interaction aspect of students’ learning alongside factors that encourage their substantive learning.

Published: May 2020

The objective of this research is to examine the effectiveness of the “Executive Function Training Program in Preschool” (EFE-P) that includes real-world activities and applies different required methodologies for a sustainable education. In addition, it is evaluated whether the improvement of executive functions is transferred to the social competence domain. The study involved 100 students aged 5–6 years, of which 50 were randomly assigned to the active control group and 50 to the experimental group. Executive functions (BRIEF-P) and social competence (BASC and PKBS-2) were measured at two time points (pre-intervention and post-intervention). Data were analyzed using the Generalized Estimating Equation (GEE) for repeated data and results showed that children in the experimental group obtained better scores on executive functions and social competence compared to their peers in the control group. It is discussed if the executive functions training can be effective in improving social competence as long as the programs include real-world activities that encourage such transfer, as the EFE-P does.
Types of Behavior of Flood Victims around Floodwaters. Correlation with Situational and Demographic Factors
Authors: Diakakis Michalis
Published: May 2020

Recently, human behavior around floodwaters has been acknowledged as one of the factors that influence the risk of fatal incidents. The present study analyzes the behavior of flood victims by developing a systematic classification of their actions at the time of the flood. Based on this taxonomy, the study examines a flood fatality database for Greece (1960–2019) to quantify the different types of behavior and to examine potential correlations with various demographical and situational factors. Results show that three-quarters of the victims exhibit a risk-taking behavior by deliberately coming in contact with floodwaters. Statistically significant associations were found between behavior and the demographics of the victims, the type surrounding environment, and the use of vehicles, indicating that certain situations and certain individuals are more prone to risk-taking behaviors than others. A statistical model shows that the behavior of a flood victim can be predicted with high accuracy by knowing certain variables of a fatal incident. The prevalence of risk-taking actions identified is a strong indication that human behavior is a crucial factor in flood mortality. The present study shows that a systematic classification of behaviors can help future interventions by highlighting the most common mechanisms of fatal incidents.
Spatial–Temporal Variations in Atmospheric Factors Contribute to SARS-CoV-2 Outbreak

Published: May 2020

The global outbreak of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection causing coronavirus disease 2019 (COVID-19) has reached over five million confirmed cases worldwide, and numbers are still growing at a fast rate. Despite the wide outbreak of the infection, a remarkable asymmetry is observed in the number of cases and in the distribution of the severity of the COVID-19 symptoms in patients with respect to the countries/regions. In the early stages of a new pathogen outbreak, it is critical to understand the dynamics of the infection transmission, in order to follow contagion over time and project the epidemiological situation in the near future. While it is possible to reason that observed variation in the number and severity of cases stems from the initial number of infected individuals, the difference in the testing policies and social aspects of community transmissions, the factors that could explain high discrepancy in areas with a similar level of healthcare still remain unknown. Here, we introduce a binary classifier based on an artificial neural network that can help in explaining those differences and that can be used to support the design of containment policies. We found that SARS-CoV-2 infection frequency positively correlates with particulate air pollutants, and specifically with particulate matter 2.5 (PM2.5), while ozone gas is oppositely related with the number of infected individuals. We propose that atmospheric air pollutants could thus serve as surrogate markers to complement the infection outbreak anticipation.

Published: May 2020

Pneumonia is the most frequent severe medical complication after stroke. An overactivation of the cholinergic signaling after stroke contributes to immunosuppression and the development of spontaneous pneumonia caused by Gram-negative pathogens. The α7 nicotinic acetylcholine receptor (α7nAChR) has already been identified as an important mediator of the anti-inflammatory pathway after stroke. However, whether the α2, α5 and α9/10 nAChR expressed in the lung also play a role in suppression of pulmonary innate immunity after stroke is unknown. In the present study, we investigate the impact of various nAChRs on aspiration-induced pneumonia after stroke. Therefore, α2, α5, α7 and α9/10 nAChR knockout (KO) mice and wild type (WT) littermates were infected with Streptococcus pneumoniae (S. pneumoniae) three days after middle cerebral artery occlusion (MCAo). One day after infection pathogen clearance, cellularity in lung and spleen, cytokine secretion in bronchoalveolar lavage (BAL) and alveolar-capillary barrier were investigated. Here, we found that deficiency of various nAChRs does not contribute to an enhanced clearance of a Gram-positive pathogen causing post-stroke pneumonia in mice. In conclusion, these findings suggest that a single nAChR is not sufficient to mediate the impaired pulmonary defense against S. pneumoniae after experimental stroke.
An Efficient Vector Control Policy for EV-Hybrid Excited Permanent-Magnet Synchronous Motor
Authors: Elsonbaty Nadia A. , Enany Mohamed A. , Hassanin Mahmoud I.
Published: May 2020

In this paper, a new control strategy for hybrid excited salient permanent-magnet synchronous motor (HEPMSM) is proposed, where both armature winding and DC field windings are located in the stator. The developed control strategy fulfills the required characteristics of the electric vehicles (EVs) and hybrid electric vehicles (HEVs) motors. A detailed mathematical model of the HEPMSM is presented. The field current (FC) is kept constant near its rated value for the high acceleration constant torque (CT) region. The conventional control usable method of reducing FC and reversing it on the motor performance characteristics through the constant power (CP) region is examined and evaluated. A proposed FC pattern is applied to three deferent operating modes of EV. High acceleration and wide stable constant power speed range without overdesign is the main target of this work. Based on the deduced optimum control pattern, the required EV-HEPMSM performance characteristics are developed. The required d–q control armature, field currents as well as d–q stator voltage components are provided for either current or voltage control technique availabilities. Simulation work is carried out on the commonly used method and on the proposed method. The obtained simulated characteristics effectively validate the target of the proposed steady-state presented analysis and pattern.

USE OF A PENETRATING ADDITIVE TO INCREASE THE WATER RESISTANCE OF CONCRETE
Authors: Abzalilova A. , Strokova V.
Published: May 2020

The penetration of moisture into the capillary-porous structure of concrete leads to the development of corrosion processes, the formation of efflorescence, the decrease in strength and the subsequent destruction of the cement-sand composite. At the same time, the increased humidity of the structure is a favorable environment for the development of various biological damages (mold, fungi, lichens), which, in turn, leads to both decrease in the operational characteristics of the structure and loss of the aesthetic appearance of the building facade. In this regard, the study of possibility of increasing the waterproofing of concrete by compaction of its structure is of great interest. The paper discusses the effect of penetrating additives on the physicomechanical characteristics of fine-grained concrete and fiber-reinforced concrete. It has been established that the introduction of a penetrating additive into the composition of cement-sand composites leads to the filling of the capillary-porous structure of materials with needle-like new formations, which makes it possible to increase their resistance to moisture influence, namely, to increase the waterproof grade, reduce the depth of water penetration into the concrete structure, increase the contact angle of wetting the surface of the material. It was also noted that the simultaneous introduction of a penetrating additive and fiber into the concrete composition allows not only to increase the waterproofness of the composite, but also to improve hydrophobic performance by imparting a hierarchical surface structure to the material.

Authors: Y Sameena , V. M. V. Enoch Israel
Published: May 2020

Magnetic nanoparticles can be used to load bio–molecules for various biophysical applications. The direct attachment of bio–molecules such as protein and DNA to magnetic nanoparticles may lead to alter their structure. A method to immobilize and store biomolecules for example DNA on to a magnetic nanoparticles surface without much structural alteration is carried out in the present work. DNA is a target for many therapeutic small molecules as therapeutic drugs bind to DNA – interfering with protein factors involved in DNA mechanism, or cleave DNA cross-link – interfering with the cell division. This may find applications in drug interactions study with the stored DNA without much alteration in their structure.

On Cauchy Numbers and Their Generalizations
Authors: KARGIN Levent
Published: May 2020

This paper is concerned with both kinds of the Cauchy numbers and their generalizations. Taking into account Mellin derivative, we relate p-Cauchy numbers of the second kind with shifted Cauchy numbers of the first kind, which yields new explicit formulas for the Cauchy numbers of the both kind. We introduce a generalization of the Cauchy numbers and investigate several properties, including recurrence relations, convolution identities and generating functions. In particular, these results give rise to new identities for Cauchy numbers.
CREUTZFELDT-JAKOB SYNDROME OF GENETIC ORIGIN: SERIES OF CASES IN THE ARGENTINIAN PATAGONIA
Authors: Exeni Díaz G. , Costa M. , Salman J. , Ávila S.
Published: May 2020

Creutzfeldt-Jakob disease (CJD) is an uncommon neurodegenerative disorder with an incidence of 1 per 1,000,000 in humans per year, typically characterized by rapidly progressive dementia, ataxia, myoclonus and behavioral changes. Genetic prion diseases, which develop due to a mutation in the prion protein gene (PRNP), account for an estimated 10 to 15% of all CJD cases. Familial CJD is transmitted with an autosomal dominant inheritance pattern with high penetrance. Worldwide, the most common mutation is E200K (glutamate to lysine). We report four families with CJD assisted in Neuquén Hospital in 2018. Three of the four index cases had family history of neurological and psychiatric illness, though data was not taken into consideration at the moment of evaluation of the new cases. The most significant data recorded for a genetic consultation was when the problem had started, and it was required by a neurologist. The initial symptoms were persistent insomnia and depression with poor response to habitual psychiatric medication. Impoverishment is fast with visual disorder, myoclonias, ataxia, dementia and loss of language. Pedigree analysis allowed the identification of 144persons with the gene potential, who can develop the disease at any time in their adulthood. In all cases, mutation E200K was identified. There is a region of increased frequency of CJD. There must be suspicion on patients with neuropsychiatric symptoms and suspected family history(familiar background). Finding of the mutation confirms the diagnosis in patients and allows the identification on pre-symptomatic individuals. Challenge is posed on gene advice and to avoid iatrogenic disorder transmission.

Published: May 2020

The micronucleus test (MN) is a biomarker of non-destructive genotoxicity that allows chromosomal damage and other nuclear alterations (NA) to be detected. Phrynops hilarii is a freshwater chelonium that inhabits regions of central-northern Argentina. The main objective was to determine the presence of MN and other NA in erythrocytes of natural populations of P. hilarii comparing their frequencies between three sites, two anthropized and one of control (cities of Diamante and Paraná) of Entre Ríos, Argentina, during the period 2015-2016. Eighteen individuals (six per sampling site) were evaluated at the sites: 1- PD: Pre-Delta National Park (control), 2- AG: Salto Ander Egg (agroecosystem) and 3- SU: Caleta Club Náutico (urban system). Blood was obtained from the femoral vein. The samples were stained with the May Grünwald-Giemsa method and observed under a microscope with an immersion objective. Micronucleus (MNF) and nuclear alterations (NAF) frequencies were determined every 1000 erythrocytes observed. A significant difference (p<0.05) was found between the PD site and the other sites (AG and SU), both for MNF (p=0.0021) and for NAF (p=0.0011). The highest frequency values ​​corresponded to the AG site (MNF: 3.33 ± 0.62; NAF: 4.67 ± 0.56). Finally, biomonitoring with P. hilarii was useful, so it could be considered as a bioindicator species to assess the quality of Argentina’s environments.

The Vehicular ad-hoc Network (VANET) is a subclass of Mobile ad-hoc networks (MANETs).VANET is a wireless network created from the concept of building a vehicle network (node) toexchange data information (data communication). There is a new concept technique forVANET communication used, namely the use of the concept of Software Defined Network(SDN) on VANET. For data communication between vehicles, a routing protocol required. Themost common routing protocol used on VANET since 2003 is AODV. In 2014 several studieswere using the SDN paradigm tried on VANET technology to improve the performance ofQuality of Service (QoS), one of which is a Geographic-based SDN, called SDGR in 2016.Multicast is a method of routing data on a network that allows one node or a group of nodes tocommunicate efficiently with the receiving node. The multicast concept supports one-to-manyrouting in nodes that send packet data to a group of nodes. The development of the SDGRrouting protocol using the idea of multicast technique to SDGR based on the Direction calledSDGR + R carried out in 2019.

Published: May 2020

A doença de Chagas foi descoberta em 1909, por Carlos Ribeiro Justiniano das Chagas. Consiste em uma infecção sistêmica de evolução essencialmente crônica, causada pelo protozoário flagelado Trypanosoma cruzi. A transmissão da doença de Chagas pela via vetorial é considerada o mecanismo de maior relevância epidemiológica. Porém, no Brasil e em vários países da América Latina a principal via de transmissão da infecção chagásica em áreas urbanas é atualmente a via transfusional, ainda considerando outras formas de transmissão. A doença de Chagas encontra-se difundida por todo continente Americano, constituindo um sério problema de saúde pública. Estima-se que o número de pessoas portadoras da infecção chagásica na América Latina varia entre 18-20 milhões de casos, de acordo com a Organização Mundial da Saúde. No Brasil, estima-se que há cerca de três milhões de portadores da doença de Chagas. A prevenção da doença de Chagas engloba vários aspectos a serem considerados como as condições de vida do indivíduo, neste caso deve-se levar em consideração sua habitação, já que moradias inadequadas é domicílio do barbeiro; o inseto vetor; a transmissão via oral; a contaminação congênita; os possíveis acidentes, e a doação de sangue.Palavras chave: Doença de Chagas; Trypanosoma cruzi; transmissão.

Introdução: O traumatismo cranioencefálico (TCE) é uma das causas mais frequentes de morbimortalidade no mundo, refletindo em um grande problema de saúde pública no Brasil. Objetivo: O presente estudo tem por finalidade analisar as características da atuação do enfermeiro a vítimas de TCE, além disso, abordar a fisiopatologia do TCE e demonstrar os benefícios da atuação do enfermeiro as vítimas desta patologia. Metodologia: Trata-se de uma revisão bibliográfica, realizada através de busca eletrônica na Base de Dados em Enfermagem, SCIELO, livros on-line e contidos no acervo da biblioteca da Faculdade de Ceres Goiás, referentes ao período de 2000 a 2014. Resultados e discussão: O conhecimento das causas do traumatismo cranioencefálico facilita a implantação de medidas para prevenção primária, visando à redução do número de traumas, sequelas e o alto índice de morbimortalidade. No entanto, para que o enfermeiro seja capaz de avaliar e prestar um atendimento de emergência adequado torna-se imprescindível conhecimento significativo, tendo em práxis treinamento intensivo e habilidades. Conclusão: Os resultados deste estudo mostraram que o exercício efetivo liderado pelo enfermeiro é essencial para conduzir à equipe de enfermagem em locais onde à tomada de decisão deve ser rápida e o atendimento sincronizado, requerendo deste profissional conhecimento científico e competência clínica.Palavras Chave: Atuação do enfermeiro.

INAPTIDÃO DE CANDIDATOS À DOAÇÃO DE SANGUE RELACIONADA À SOROPOSITIVIDADE PARA INFECÇÃO CHAGÁSICA NAS DIFERENTES REGIÕES DO BRASIL
Authors: Costa Milce , Silva Juliane Santos , Muniz Valkíria dos Reis Carvalho
Published: May 2020

Introdução: A doença de Chagas é uma infecção sistêmica de evolução crônica que tem como agente etiológico o protozoário monoflagelado Trypanosoma cruzi. A transmissão por transfusão sanguínea tem importante relevância epidemiológica, uma vez que corresponde de 5 a 20% dos casos descritos na literatura. Objetivo: Analisar a prevalência de inaptidão em candidatos à doação de sangue com sorologia positiva para Chagas por regiões do Brasil entre os anos de 2000 a 2013. Metodologia: Trata-se de uma revisão bibliográfica, de aspecto quantitativo. Resultados e Discussão: As maiores prevalências de doadores inaptos com sorologia positiva para doença de Chagas ocorreram na região Nordeste, especificamente na cidade de Iguatu-CE e na região Sudeste, na cidade de Patos de Minas-MG, com percentuais de 1,90% e 1,20% respectivamente. Diante destes dados pode-se presumir que nestas localidades não houve triagem sorológica adequada no serviço de hemoterapia bem como o combate ao vetor apresentou falhas. A região Sudeste foi a que apresentou a maioria das prevalências abaixo do índice de prevalência de doadores chagásicos, tal situação pode ser justificada pelo fato das cidades pesquisadas não serem regiões endêmicas para doença de Chagas, bem como pelo combate sistemático ao vetor nestes locais. Conclusão: A realização de pesquisas verificando doadores inaptos com sorologia positiva para doença de Chagas em bancos de sangue nas diferentes regiões do Brasil é de extrema relevância para avaliar a situação transfusional peculiar dos hemocentros de cada região com o intuito de traçar estratégias locais para eliminar a transmissão da doença de Chagas por transfusão sanguínea. Palavras-chaves: Doença de Chagas. Transfusão sanguínea. Doadores de sangue.

INTRODUÇÃO: A água é definida como uma substância líquida, incolor, transparente e insípida. Para o consumo humano, a água deve apresentar-se livre de impurezas. Sua contaminação por micro-organismos pode resultar em diversos danos à saúde humana. As águas subterrâneas usadas no consumo humano são uma importante fonte de contaminação por micro-organismos, que traz como consequência, a contração de doenças. OBJETIVO: O presente trabalho objetivou verificar a qualidade microbiológica da água subterrânea obtida de poços rasos do bairro Jardim Cachoeira, na cidade de Carmo do Rio Verde-GO. METODOLOGIA: Foram coletadas amostras da água de 10 poços. As amostras foram enviadas ao LAFARM- Laboratório Analítico Farmacêutico Ltda., onde foi realizada a contagem em placa de bactérias heterotróficas, e a determinação de presença ou ausência de coliformes totais e de Escherichia coli por método enzimático, que detecta a presença da enzima β-D-galactosidase, produzida pelos micro-organismos do grupo coliformes totais, e da enzima β-Glucuronidase, produzida por bactérias do grupo Escherichia coli. RESULTADOS E DISCUSSÃO: Do total de 10 amostras coletadas, todas apresentaram uma grande carga de bactérias heterotróficas. Em todas as amostras, detectou-se a contaminação por coliformes totais. Em 5 amostras foi detectada a contaminação por Escherichia coli. Estes resultados demonstram que as águas analisadas apresentam contaminação por micro-organismos, sendo que, 50% deles por micro-organismos de origem fecal. CONCLUSÃO: Todas as amostras apresentaram carga de contaminação bacteriana acima dos limites aceitáveis, sendo, portanto, consideradas impróprias para o consumo humano.
