Recent and projected shifts from surface density compensation to warming, freshening and stronger stratification in the subpolar North Atlantic
Authors: Marsh Robert , Dey Dipanjan , Lenn Yueng-Djern , Roberts Emyr Martyn
Published: December 2023

The hydrography and stratification of the subpolar North Atlantic is highly variable, with convection activating and deactivating across parts of the Labrador and Irminger seas. Likely consequential for the Atlantic Meridional Overturning Circulation (AMOC), this variability is examined in an eddy-resolving ocean model hindcast spanning 1958-2021 and in 1950-2050 simulations with four climate models, spanning differences in ocean resolution (eddy resolving or permitting), code and implementation. Stratification of the Labrador and Irminger seas is quantified with the Potential Energy Anomaly (PEA) in the upper 1000 m of the water column. Monthly PEA anomalies are evaluated alongside corresponding anomalies of sea surface temperature, salinity, and density. For 30-year windows, moving correlations between PEA and surface properties are obtained over the 100-year simulations to characterize the evolving relationships. As climate change progresses, stratification in three of the four models is increasingly associated with variable surface salinity, in both regions. Lagrangian analyses of surface flow pathways in the decades preceding 1990 and 2040, for one of the models in which surface salinity grows in influence, indicate that the subpolar presence of fresh Arctic waters and saline Atlantic waters increase and decrease respectively by 2040. Furthermore, in three of the four models, surface density compensation associated with correlation of surface temperature and salinity anomalies is progressively replaced by combined surface warming and freshening, lowering surface density, and strengthening stratification. The extent of these model-dependent changes and processes are of consequence for the projected fate of the AMOC by the mid 21st century.

Authors: Baloch Muhammad Daniyal , Abduhaer Abulaiti
Published: December 2023

Background Elevated Gamma Glutamyl transferase (GGT) and uric acid levels have been associated with worse outcomes in critically ill patients, but their predictive value in Pediatric Intensive Care Unit (PICU) patients is unclear. We conducted a systematic review and meta-analysis to evaluate the association between GGT/uric acid and mortality in PICU patients.Methods PubMed, Embase and Cochrane Library were searched for observational studies examining the association between GGT/uric acid levels and mortality in PICU patients. Pooled risk ratios (R.R.) with 95% confidence intervals (CI) were calculated using random-effects models.Results 8 studies with 2,134 patients were included. Elevated GGT was associated with significantly higher mortality risk (RR 1.86, 95% CI 1.34–2.58). The association remained significant when restricted to multivariate analyses (RR 1.95, 95% CI 1.17–3.26). Elevated uric acid levels were also associated with higher mortality (RR 1.97, 95% CI 1.33–2.90). Significant heterogeneity was present.Conclusions Elevated Gamma Glutamyl transferase (GGT) and uric acid levels are associated with higher mortality risk in Pediatric Intensive Care Unit (PICU) patients. These biomarkers may assist in risk stratification, although additional studies are needed to confirm these findings.
Thermal Analysis and Crystallization of MY(Sb70Te30)100-Y (M = Ag, Sn; Y = 0, 7.5) Amorphous Thin Films
Authors: Rocca Javier , Ureña María Andrea , Fontana Marcelo
Published: December 2023

Antimony-telluride based phase-change materials doped with different metals have been proposed to be ideal materials for improving the performance of phase-change memories. It is well known that Sb70Te30 thin films show a sharp fall in the electrical resistance in a narrow temperature range when heating. Therefore, it is interesting to study the effect of adding metallic atoms into this composition. In this work, the crystallization of My(Sb0.70Te0.30)100-y (M = Ag, Sn; y = 0, 7.5) amorphous thin films, obtained by pulsed laser deposition, has been studied by means of differential scanning calorimetry under continuous heating regime. The as-deposited samples and the crystallization products have been characterized by X-ray diffraction. The crystallization and melting temperatures were determined, as well as the enthalpies involved in such processes. The activation energy for crystallization was also determined. From the obtained results, it is observed that the addition of metals shifts the crystallization process to higher temperatures around 15-25 K and increases its activation energy. The transformation diagrams (Temperature-Time-Transformation and Temperature-Heating rate-Transformation) are calculated. The experimental results are discussed and correlated with proposed structures for the glass and the crystalline states. The present results are also compared with those reported by other authors.

Published: December 2023

People worldwide are familiar with the health benefits of juices that are extracted from a variety of readily available fruits. The abundance, flavor, and health benefits of mangos make them a valuable fruit. Mango extract is used to make mango juice. Thus, research on mango juice is required to assess its nutritional value using various nutrient parameters and comparative analyses. Because of the chemicals (such as sulfur dioxide and sodium benzoate) added to the ingredients and the high concentration of microorganisms (yeast, mold), processed mango juice may not always be safe. All age groups agree that mango juice is the most popular non-alcoholic beverage in the world. In order to determine the pH, moisture content, TSS, TTA, protein, ash content, fat, and vitamin C values of the raw and processed mango juices from various local companies that are sold in the Arba Minch markets, our research looked at the following values: 3.95, 84.20, 13.91, 0.13, 1.4, 0.61, 0.51 and 28.87, 87.14, 12.19, 0.10, 0.99,0.73, 0.51, 39.18, respectively. The conventional physical and chemical methods determine all the parameters. This study shows that a significant number of various kinds of these nutritional components can be found in mango juices. The study's findings were contrasted with the original mango extract, which will help consumers evaluate the safety and nutritional value of mango juices. It was discovered that raw juice was more widely accepted than processed juice. The study suggests that juice be consumed raw by humans.

Authors: Piddubnyi Artem , Tkachenko Iryna , Shubin Pavlo , Korenkov Oleksii
Published: December 2023

Introduction. Ovarian cancer is an oncogynecological disease with high mortality. High mortality caused by this pathology is associated with diagnosis at the III–IV stage of the disease. This stage of the disease is characterized by metastasis and reflected in the 5-year survival rate, decreasing to 30.2 %. At the same time, when diagnosed at the I-II stage, this indicator is 92.6%.
The aim of the work is bibliometric analysis and generalization of data from scientific sources on the study of ovarian cancer metastasis.
Materials and methods. Information was searched on electronic resources of the Scopus, Web of Science, PubMed, and Google Scholar databases using the keywords "ovarian cancer" and "metastases." An online platform for monitoring and analyzing scientific sources was used for bibliometric analysis. We used several VOSviewer bibliometric network visualization system tools and SciVal (Scopus) modern citation requirements.
Results. It has been established that metastasis of ovarian cancer can occur in several ways and depends on the conditions of the tumor microenvironment. The influence of E-cadherin, MMP-2, and transglutaminase-2 on metastasis processes was evaluated. Also, the role of cytokines in the invasiveness of the tumor process and metastasis was established. The results of bibliometric analysis of scientific sources showed that over the past 20 years, the number of publications on ovarian cancer metastasis has increased significantly, and the most widely given topic is studied in the USA and China.
Conclusions. Metastasis of ovarian cancer can occur in several ways and depends on the conditions of the tumor microenvironment. It was found that among the analyzed 496 publications, the most relevant directions are molecular-biological and signaling pathways, which are described in many ways in scientific sources on ovarian cancer metastasis. The calcification of peritoneal metastases and their formation mechanism are currently not investigated, and there is no thorough explanation that may become a perspective for further research.

Published: December 2023

Study objectives. This study aims to investigate potential differences in sleep parameters between children with metabolic syndrome (MetS) and their healthy counterparts using the portable cardiorespiratory monitoring device SOMNOcheck micro CARDIO.
Methods. The study included 71 children and adolescents aged 10 to 17 years, with 39 in the MetS group and 32 in the control group. The main anthropometric parameters were: neck circumference (NC), waist circumference (WC) and waist-to-height ratio (WHtR). All children were assessed using the Friedman tongue position (FTP) scale. Children completed the Epworth Sleepiness Scale for Children and Adolescents (ESS-CHAD) and the Montreal Cognitive Assessment (MoCA). Salivary cortisol was collected in the morning immediately after waking up. The sleep study was performed using a portable SOMNOcheck micro CARDIO device with a special cardiaс sensor. Statistical analysis of the data was performed using EZR version 1.61.
Results. Significant differences in cardiorespiratory sleep monitoring were observed between between the MetS and non-MetS groups. Patients with MetS had higher daytime sleepiness scores and lower MoCA scores compared to the control group. Cortisol levels in morning saliva showed a marked increase among children with obstructive apnea/hypopnea index ≥ 1. A logistic regression model established a link between FTP stages III and IV and the autonomous arousal index.
Conclusions. These findings highlight the differences (p < 0.05) in sleep-related parameters between the MetS and non-MetS groups, which may indicate an increased risk of sleep-disordered breathing and cognitive impairment in such children.

The Relationship Between Employee Attitudes in the Pygmalion Effect and Trust in Supervisors: A Study on Hotel Establishments
Authors: DEMİRDAĞ Şerif Ahmet , TURPCU Eray
Published: December 2023

Regardless of the type of business, the common goal of every establishment is to make sustainable profits and thus to ensure its continuity. In the service sector, which also includes tourism establishments, where social relations and labor power are intense, the productivity and profitability of establishments completely depend on the human factor. For this reason, the managers in these establishments want to get the highest benefit from the employees and they enter into an expectation in this direction. Managers who expect employees to show higher performance reveal these expectations by showing interest to their employees. This situation is referred to as the “Pygmalion effect” in the literature. On the other hand, in addition to this effect, the trust of the employees in their supervisors plays an important role in increasing the productivity in the establishments. The aim of this study is to reveal the relationship/effect between the attitudes of employees working in hotels towards the Pygmalion effect and their level of trust in the supervisor. This study only covers employees of four-star and five-star hotels operating in Istanbul. In the study, only the Pygmalion effect and trust in the supervisor variables of the participants were discussed, and other forms of organizational behavior were not focused on. The important factor here is the resources and transportation allocated to the study, especially time limitation. Questionnaire technique was used as a data collection tool, and 423 usable questionnaires were obtained from four-star and five-star hotels operating in Istanbul. According to the findings obtained from the analysis of the data, it was found that the participants' perception of the Pygmalion effect and their level of trust in the supervisor were high. When the relations and effects between the variables were examined, it was observed that there were weak relationships between the attitudes in the Pygmalion effect of the participants and their level of trust in the supervisor. On the other hand, it was determined that there was a very weak relationship between Pygmalion effect attitude in the “general self-efficacy (GSE)” dimension and trust in the supervisor, a very weak relationship between the Pygmalion effect attitude in the “managerial self-efficacy (MSE)” dimension and trust in the supervisor, and a weak relationship between the Pygmalion effect attitude in the “Pygmalion Attitude Index (PAI)” dimension and trust in the supervisor.

Multi-Objective Optimization for IRS-Aidded Multi-user MIMO SWIPT Systems
Authors: Quyet Pham Van , Kha Ha Hoang
Published: December 2023

In this paper, we investigate an intelligent reflecting surface (IRS) assisted simultaneous wireless information and power transfer (SWIPT) system in which users equipped with multiple antennas exploit power-splitting (PS) strategies for simultaneously information decoding (ID) and energy harvesting (EH). Different from the majority of previous studies which focused on single objective optimization problems (SOOPs) and assumed the linearity of EH models, in this paper, we aim at studying the multi-objective optimization problem (MOOP) of the sum rate (SR) and the totalharvested energy (HE) subject to the maximum transmit power (TP) constraint, the user quality of service (QoS), and HE requirements at each user with taking a practical non-linear EH (NLEH) model into consideration. To investigate insightful tradeoffs between the achievable SR and total HE, we adopt the modified weighted Tchebycheff method to transform the MOOP into a SOOP. However, solving the SOOPs and modified SOOP is mathematically difficult due to the non-convexity of the object functions and the constraints of the coupled variables of the  base station (BS) transmit precoding matrices (TPMs), the user PS ratios (PSRs), and the IRS phase shift matrix (PSM). To address these challenges, an alternating optimization (AO) framework is used to decompose the formulated design problem into sub-problems. In addition, we apply the majorization-minimization (MM) approach to transform the sub-problems into convex optimization ones. Finally,  numerical simulation results are conducted to verify the tradeoffs between the SR and the total amount of HE. The numerical results also indicate that the considered system using the IRS with optimal phase shifts provides considerable performance improvement in terms of the achievable SR and HE as compared to the counterparts without using the IRS or with the IRS of fixed phase shifts.
Performance Analysis of Gradient Inversion Attack in Federated Learning with Healthcare Systems
Authors: Dao Thi-Nga , Nguyen Tien Phat
Published: December 2023

Federated learning (FL) is widely applied to healthcare systems with the primary aim of keeping the privacy of patient's data while improving classification quality by using knowledge from multiple participants. However, the training images are believed to be embedded into the shared gradient, which indicates a privacy risk when sharing the gradient with other participants in FL. Therefore, this work aims to design and evaluate an image recovery attack on medical images. More specifically, dummy images are trained to match the dummy gradient to the shared gradient while maintaining the smoothness and naturalness of reconstructed images. On the adversary side, an optimization problem is formulated with variables of dummy images and network parameters treated as constants. We evaluate the gradient attack on two medical datasets and reconstructed images clearly show the details of chest X-ray and MRI images including bone and blood vessels of captured areas. Our work aims to increase the awareness of people on sharing the gradient in FL, especially in healthcare systems.

Authors: CANBOLAT Gökhan
Published: December 2023

Numerical studies on stress, deformation, and damages due to fluid flow have been highly carried out using Fluid-Structure Interaction (FSI) in recent years. FSI is highly efficient in investigating a solid domain deformed by the fluid flow. In this study, a one-way fluid-structure interaction study is performed by a straight pipe under different pressure and thermal conditions. Here, the thermophysical properties of the fluid and mechanical properties of the solid domain can be subjected to change during fluid flow. An aluminum straight pipe with a 1 mm wall thickness is operated under 1 Bar, 5 Bar, and 10 Bar with three different surface temperatures -10ºC, 20ºC, and 50ºC. This study aims to investigate the structural variation of aluminum by the temperature and pressure change of operating fluid in the pipe. Variation of thermophysical properties of fluid by heated pipe surface is integrated into the numerical analysis by generated functions. Numerical analysis showed that the variation of temperature in operating fluid highly affects the fluid characteristic and the structural response of the solid domain by different temperatures. An increase in the operating pressure caused maximum deformation to approximately %100 from 1 Bar to 5 Bar, and approximately %120 from 1 Bar to 10 Bar for the adiabatic process as expected but in the heating conditions stress is nearly three times higher than cooling conditions. As a result, one-way FSI solutions are highly effective in investigating the deformed solid domain as a result of flow, thermal, and operating conditions.

Elektromekanik düşük frekanslı salınımlar, büyük çaplı enterkonnekte güç sistemlerinin kararlılığı için başlıca kaygılar arasındadır. Etki ettikleri sistem bileşenlerine bağlı olarak bu düşük frekanslı salınımlar, lokal salınımlar, alanlar arası salınımlar, kontrol modu salınımları veya burulma modu salınımları olarak sınıflandırılabilirler. Alanlar arası salınım, birbirlerine zayıf bağlantı hatları ile bağlı yüksek miktarda güç transferinin yapıldığı iki alanda bulunan generatör gruplarının birbirlerine karşı salınımları ile meydana gelmektedir. Generatörlerin uyarım sistemine ek bir sönümleme sinyali eklenmesi için kurulan güç sistemi kararlaştırıcıları (PSS) lokal modların sönümlendirilmesinde oldukça etkili bir çözüm iken alanlar arası modların sönümlendirilmesinde yetersiz kalmaktadırlar. Bunun nedeni alanlar arası modların gözlemlenebilirliğinin lokal sinyallerde düşük olmasıdır.

Güç sistemlerinde güç aktarım kontrolü ve geçici durum kararlılığı sağlama gibi amaçlarla kullanılan Tristör Kontrollü Seri Kompanzatör (TCSC) cihazlar, alanlar arası modların gözlemlenebilirliğinin yüksek olduğu sinyallere (global sinyaller) doğrudan erişimi sağlandığında bu modların sönümlendirilmesine de katkı vermektedirler. Global sinyal tabanlı PSS ve TCSC cihazların koordineli kullanımıyla alanlar arası salınım modlarının sönümlendirilmesinde etkili sonuçlar alınmaktadır. Bu çalışmada alanlar arası salınım çalışmalarında referans model olarak kullanılan 2 alanlı 4 generatörlü güç sistemi için TCSC tabanlı bir geniş alan sönümleme kontrol sistemi tasarlanmıştır. Sönümleme performansı öncelikle sistemde sadece TCSC aktif iken değerlendirilmiştir. Sonrasında global sinyal tabanlı bir PSS, TCSC üzerinden sisteme eklenmiş ve performans değerlendirmesi yeniden yapılmıştır. Benzetim sonuçları ile global PSS ve TCSC’nin koordineli kullanımıyla hem alanlar arası salınımın modlarının başarıyla sönümlendirildiği hem de alanlar arası güç aktarımının iyileştirildiği gösterilmiştir.
Campo educativo, práctica docente y políticas educativas en Colombia

Este artículo se enfoca en explorar la relación entre las políticas educativas en Colombia, específicamente las orientaciones curriculares, los procesos educativos y la práctica docente. El análisis se basa en tres conceptos clave: a) la noción de campo, resaltando su independencia dentro del Estado; b) el poder social que el Estado ejerce sobre diversos campos, incluido el educativo; y c) el papel autónomo del docente dentro del aparente control estatal a través de normativas y orientaciones educativas, examinado desde tres perspectivas: la tendencia a mantener prácticas tradicionales de enseñanza, la resistencia a implementar las directrices de políticas públicas en la educación, y la importancia de la reflexión como elemento esencial para el desarrollo profesional y la mejora de las prácticas educativas.

La enseñanza y aprendizaje remotos por emergencia durante pandemia han demostrado la urgente necesidad de capacitar a los docentes en la incorporación tecnología al aula de clase. En la enseñanza del inglés (ELT), esta necesidad se convierte en una exigencia debido a que el uso de herramientas digitales posibilita el desarrollo de la competencia cultural e intercultural mediante el acercamiento de los estudiantes a registros auténticos en hablantes nativos, y variaciones de la lengua objetivo en hablantes de inglés pertenecientes a otras lenguas. La revisión literaria demuestra que modelos, como el T-Pack de Mishra and Koehler’s, el SAMR de Puentedura, y el SOSE de Salem, muestran como guiar este proceso de integración de las TIC en educación en general, pero no existe un diseño didáctico que describa concretamente los procedimientos para capacitar docentes de inglés. El presente artículo busca describir y sustentar teóricamente un Diseño Didáctico basado en la Web para entrenar docentes de inglés en el uso de las TIC en ELT. El Diseño es parte de la fase de intervención de un estudio que persigue establecer sus efectos en la Competencia Digital Docente utilizando el marco del DigCompEdu en tres poblaciones de docentes de inglés en Colombia.
Nomes próprios e humor agressivo nas redes sociais
Authors: Possenti Sírio
Published: December 2023

Este artigo apresenta um conjunto de piadas que funcionam basicamente segundo o seguinte procedimento: ler um nome próprio como se não designasse um indivíduo, mas como se fosse um enunciado de tamanho variável que se refere a classes de indivíduos, a ações, que são declarações. Por exemplo, “Eu pinto paredes; o Jânio Quadros”, “Lima Maria” (lhe mamaria), “Jorge, O Ringo Star?” (O Ringo está?) etc. Em geral, ocorrem pequenas alterações de sons ou diferentes separações das sequências (star / está), obrigando o leitor a descobrir outro enunciado sob um enunciado que é ou parece ser um nome próprio, o que implica teorias da leitura que vão além da relação som-letra. Às vezes se trata de uma piada inocente, mero jogo de linguagem. Em outros casos, pessoas ou grupos são objeto de derrisão.

Em face de inquietações teórico-metodológicas vivenciadas em uma pesquisa conduzida durante a pandemia de COVID-19, este artigo problematiza as atividades que legitimaram o trabalho antropológico ao longo do que Mariza Peirano chamou de história-e-teoria da Antropologia, a fim de abordar a seguinte questão: é possível produzir conhecimento antropológico sem etnografia? Partindo da antropologia moderna e de sua ênfase no “trabalho de campo”, passamos também pelo interpretativismo de Clifford Geertz, pela preocupação dos pós-modernos com a autoridade etnográfica e pela ideia de “momento etnográfico” de Marilyn Strathern. Finalmente, a fim de evidenciar uma nova proposta antropológica, a qual desassocia a disciplina da prática da etnografia, abordamos a ideia de “correspondência” de Tim Ingold.

RESUMO

Introdução: Compreende-se estomia como uma intervenção cirúrgica cujo objetivo é estabelecer a comunicação entre um órgão e o meio externo, sendo sua denominação de acordo com o órgão exteriorizado. No Brasil a pessoa estomizada é contemplada com diretrizes e políticas públicas, além de ser entendida como uma deficiência, sendo necessário assim um cuidado integral, exigindo do profissional que presta a assistência e/ou orientação educação permanente. Objetivo: Relatar acerca da capacitação sobre cuidados de enfermagem com estomias intestinais aos enfermeiros atuantes na Secretaria Municipal de São Bento do Sul/Santa Catarina(SC) Metodologia:Trata-se de um estudo descritivo qualitativo do tipo relato de experiência, que se deu através de capacitação realizada em Junho de 2022, com os enfermeiros que atuam na secretaria municipal de saúde de São Bento do Sul/SC, o qual conta com 44 enfermeiros atuantes em 21 unidades básicas de saúde (UBS), com a temática 'cuidados de enfermagem com estomia de eliminação' , tendo o mesmo sido ministrado por enfermeira estomaterapeuta no formato presencial com discussão teórica e prática. Resultados e discussão: O Ministério da Saúde (MS) em parceria com o Ministério da Educação (ME) vem incentivando práticas formativas aos profissionais inseridos nos serviços, as quais estão amparadas na Política Nacional de Educação Permanente. Uma vez que a formação de enfermeiros no Brasil é generalista, os cursos e capacitação se tornam uma ferramenta fundamental para uma atuação reflexiva. Assim, dos 44 enfermeiros atuantes no município , participaram do treinamento 21 (47,72%), atendendo ao critério de ao menos um profissional por UBS , podendo este ser um multiplicador de conhecimento, estratégia importante da educação permanente em saúde. A capacitação em sua parte teórica abordava questões anatomofisiológicas e possíveis complicações, enquanto que na parte prática foram tratados estudos de caso e oficinas, com simulação,  a fim de desenvolver o raciocínio clínico. Ao final do curso, foram desenvolvidos fluxos de atendimento com os participantes,  buscando a descentralização do cuidado para as unidades básicas de cada enfermeiro, favorecendo a criação de vínculo dos pacientes com a equipe de saúde. Conclusões: Visto que um profissional orientado e seguro em sua prática implica diretamente na segurança do paciente, nesse sentido a realização de atividades como cursos, capacitações e eventos, principalmente quando se trata de pacientes estomizados, os quais geralmente sofrem com a resistência dos profissionais para realizar seu atendimento justamente por conta da insegurança, se tornam importantes ferramentas de aprimoramento profissional.

CONTRIBUIÇÕES DA EDUCAÇÃO PERMANENTE PARA OS CONSELHOS DE SAÚDE: UM ESTUDO DE REVISÃO INTEGRATIVA
Authors: Pessoa Giuliano Silva , Barbosa Aldenisia Alves Albuquerque , Castro Janete Lima de , Lima Rafael Rodolfo Tomaz de
Published: December 2023

Introdução: A educação permanente propicia uma reflexão contínua frente à realidade posta e nos instiga a buscar soluções criativas para a superação dos problemas de saúde e, por conseguinte, qualificar as ações dos conselheiros de saúde, no intuito de aumentar a resolubilidade, a qualificação técnica e a eficiência do sistema de saúde. Objetivo: Analisar as contribuições da educação permanente para os Conselhos de Saúde. Metodologia: Trata-se de uma revisão integrativa da literatura científica guiada pelo checklist Indicativos de Qualidade para Artigos de Revisão Integrativa, realizada em julho de 2021 e atualizada em junho de 2023. Resultados: Os 15 artigos incluídos na amostra final versam, em sua maioria, sobre os Conselhos Municipais de Saúde (73%), são decorrentes de estudos realizados no Sudeste do Brasil (60%) e foram publicados nos últimos vinte anos, com maior frequência em 2011 (20%). As congruências identificadas nos artigos foram organizadas em três categorias: 1) O papel do conselheiro de saúde; 2) Desafios encontrados no exercício do controle social; 3) A qualificação para o aperfeiçoamento dos processos decisórios dos Conselhos de Saúde. Os achados do estudo mostram que a falta de conhecimentos específicos e a ausência de ações de educação permanente para os conselheiros de saúde dificultam os processos decisórios e deliberativos dos Conselhos de Saúde. Conclusões: As consequências da falta de conhecimento sobre os temas pertinentes ao exercício do controle social têm grande influência na condução de políticas públicas e do sistema de saúde no Brasil.
