Resumo: Este estudo buscou compreender facilitadores, barreiras e estratégias para o uso de marcadores do consumo alimentar por profissionais da atenção primária à saúde (APS). As respostas de 235 profissionais de saúde a um questionário eletrônico foram utilizadas para desenvolver um roteiro para grupos focais realizados virtualmente. Em 10 grupos focais, 34 profissionais de cargos assistenciais e gestão de todas as macrorregiões brasileiras foram incluídos e as transcrições das gravações foram analisadas tematicamente. Profissionais da assistência e gestores enfatizaram a necessidade de infraestrutura para o uso adequado dos marcadores, apontando falta de equipamentos e instabilidade na conexão como principais barreiras. Gestores destacaram a possibilidade de uso por qualquer profissional como facilitadora, ao passo que profissionais da assistência assinalaram positivamente a estrutura dos marcadores, mas a falta de sensibilização sobre sua importância foi mencionada como barreira pelos participantes. Apesar da lentidão, a acessibilidade das plataformas para registro dos marcadores foi apontada como facilidade, assim como a condicionalidade com políticas públicas, especialmente quando vinculadas a incentivos financeiros. Os grupos focais permitiram trocas de estratégias, como educação permanente, treinamentos para digitadores, formas de uso dos marcadores nos espaços de assistência à saúde e ampliação da divulgação dos dados. Investir em infraestrutura, qualificação profissional e colaboração entre equipes da APS, com compartilhamento de estratégias, foram fatores cruciais para fortalecer o uso dos marcadores do consumo alimentar.
Analysis o fluid flow in Lapple cyclone using analytical method and computer modelling
Authors: Oliveira Junior Givaldo Leopoldo de , Bentes Flavio Maldonado
Published: February 2025

ABSTRACT Cyclones are industrial equipment widely used to induce the separation of suspended solid particles based on a driving force related to the terminal velocity in fluid flow. They are applicable to both gaseous and liquid fluids (hydrocyclones), enabling separation between the solid-fluid physical states. The physical principle behind the separation and operation phenomenon is inertia, utilizing centrifugal force to displace air, consequently facilitating the removal of particulate matter present in the stream. One of its main functions is gas cleaning in industrial processes, due to its low acquisition, operation, and maintenance costs, along with the ability to handle streams at high pressures and temperatures. The primary objective of this study is to simulate the flow and disaggregation profiles in a cyclonic separator using computational fluid dynamics (CFD) via finite volumes, where a control volume is subdivided into discrete elements aimed at referencing points within the continuous domain. This approach enables the application of constitutive equations, converting partial differential equations into systems of linear equations. This study applies the method to a Lapple-type cyclone, validating the numerical results obtained with those available in the scientific literature under the same operating conditions. The comparative parameter used to estimate the relative error was the pressure drop. As a secondary objective, the applicability of the cyclone for neutralizing the hazardous chemical agent ammonia was evaluated. This was achieved through its chemical reaction with acetic acid, enabling a realistic hypothetical leakage study to investigate the possibility of formulating emergency plans. In the event of an industrial accident involving ammonia dispersion, this system could be activated. For this purpose, a multiphase plug flow reactor (PFR) was designed, estimating the conversion, reaction time, and dynamic concentration profiles for the synthesis of ammonium acetate, a chemical agent with lower toxicity compared to ammonia.

ABSTRACT In order to investigate the effect of periodic solar radiation on oil vapor diffusion and small breathing losses in dome roof tanks, a theoretical model of unsteady heat and mass transfer in dome tanks is established based on the ASHRAE clear-sky model and oil evaporation theory. The heat flux UDF is self-programmed, and CFD software is used to simulate the heat and mass transfer process in the gas space of the dome tank. Dynamic mesh technology is used to realize the overpressure relief of the breathing valve and calculate the small breathing losses. The results show that the gas space temperature decreases from top to bottom; it has a concave and convex distribution near the tank wall. The average temperature decreases with increasing liquid level. The vapor concentration in the gas space increases from top to bottom, and there is a clear concentration layer near the liquid level. The average vapor concentration increases with the liquid level. Gas space pressure increases gradually from top to bottom. The number of breathing valve exhausts decreases with the increase in liquid level. The small breathing losses increase with the liquid level and the seasonal warming, and the loss rate increases with the seasonal warming.

ABSTRACT Lead is a hazardous heavy metal known for its severe health impacts, including its association with cancer. In this study, copper-doped activated carbon was synthesized using copper acetate and bean husk, activated chemically through potassium hydroxide (KOH). The data was fitted by the Langmuir isotherm model more accurately than by any other isotherm, and the adsorption capacity of Cu-AC nanoparticles was found to be 94.339 mg/g. For the removal of lead ions over Cu-AC nano-adsorbent, when comparing the values of qe calculated and qe experimental. Activated copper doped carbon has the capacity to operate as an adsorbent in the treatment of lead metal ion pollution and other associated heavy metal ion pollutants. Surface chemistry analysis identified hydroxyl, amino, aromatic, and carbonyl functional groups. Field emission scanning electron microscopy revealed interconnected mesoporous structures with numerous open pores. Adsorption experiments demonstrated that the sorption process aligned. The maximum adsorption capacity was recorded at 94.339 mg/g, with a significant desorption efficiency using HCl as the desorbing agent. Thermodynamic analysis confirmed that the lead ion removal occurred primarily through a physisorption mechanism.

Published: February 2025

ABSTRACT This research paper aims to develop hybrid fibre-reinforced Engineered Cementitious Composites (ECC) deploying different modulus of fibre and to explore the mechanical and flexural response of newly refined Hybrid ECC in the 30 mm thick bottom layer of reinforced concrete (RC) beams. This investigation uses five combinations in the RC beam. The focus of hybridization is to increase the flexural response and structural functioning of RC beams. ECC mixes were attempted with the deployment of Polyvinyl Alcohol (PVA) Fibre and Polypropylene (PP) fibre with 2% as a mono fibremix. Hybridization is made with 0.65% of PVA and 1.35% of PP, 1% of PVA and 1% of PP, 1.35% of PVA, and 0.65% of PP. In this research investigation, mono fibre ECC with 2.0 % PVA fibre mix was taken as a base mix for comparison. From the behavior of the beam, it was found that the mix with PVA fibre of 1.35% hybrid with PP fibre of 0.65% exhibited better performance in flexural when compared with conventional concrete. However, PP fibre of 2% volume fraction has high energy absorption capacity, and PVA fibre of 2% volume fraction has high ductile displacement compared to conventional concrete.

Published: February 2025

ABSTRACT Micro/meso fabrication techniques have gained significant recognition globally for their advanced manufacturing capabilities. Among these, microforming stands out as a leading process in micromanufacturing. Despite growing interest in microextrusion for industrial applications, the technology remains underdeveloped compared to conventional forming methods, with limited expertise available. To address this gap, it is essential to develop a comprehensive understanding of the microextrusion process, which can guide the production of metallic microcomponents. This research focuses on the numerical simulation of microextrusion to study the influence of die entry angles on the deformation behavior of AA6063 aluminum alloy. Simulations were conducted using die angles of 15°, 30°, 45°, and 60° under varying frictional conditions. Results show a direct relationship between die angle and forming load, while punch displacement decreases as the die angle increases. The role of friction was also found to be crucial in the extrusion process. Numerical results for the 30° die angle were compared with experimental data, highlighting the effectiveness of finite element analysis in predicting microforming outcomes. This study demonstrates the potential of numerical simulation as a powerful tool for optimizing microforming processes in industrial applications.

Abstract The study aimed to identify species of the genus Crassostrea from Rio Grande do Sul and to trace the identity of C. praia, a species recognized under conchological or distributive precepts of native oyster species occurring in an ecological gradient beyond mangrove vegetation. To achieve this, oysters were collected in the southernmost region of Brazil (RS) for morphological and molecular identification of C. praia. The specimens were subjected to a diagnostic PCR-RFLP analysis and sequencing of the mitochondrial 16S rDNA gene. Based on the molecular identity of the specimens, a comparative anatomical assessment was made, involving the sizes of the mantle and the labial palps, the shapes of the accessory heart, heart, and anus, and pattern of the tentacles on the edge of the mantle. The molecular results showed the presence of two species in RS: C. rhizophorae and C. gasar, with the latter being a new occurrence for regions beyond mangrove vegetation. C. praia proved to be conspecific with C. rhizophorae, being its synonym. Anatomical data related to the species are plastic and incapable of generating specific criteria for identification between C. gasar and C. rhizophorae. Regarding the shell criteria used to promote the construction of the C. praia entity, they are deeply related to environmental conditions and the effect of population density on its conchological characters, since its molecular identity indicates that this species is synonymous with C. rhizophorae.

Abstract Background Despite considerable study, there is still no consensus defining the ideal compression regimen after ablation of the great saphenous vein with radio frequency or endolaser. Objective To identify the Brazilian Society of Angiology and Vascular Surgery members’ current compression therapy practices after ablation of the great saphenous vein. Methods A multiple-choice electronic questionnaire on post-endovenous ablation compression was developed and made available on-line to Brazilian vascular surgeons for 60 days. Results A total of 430 responses were received, 362 (84.2%) of which were considered valid. Laser ablation was the predominant technique (73.5%) and the majority of procedures were conducted in hospitals or day hospitals. Ninety-four percent of the surgeons treated associated varicose veins in the same procedure, for which phlebectomy was the technique most employed. After ablation of the great saphenous vein, 99% of the surgeons applied compression immediately; 34.3% used 35 mmHg compression stockings, 26% preferred crepe bandages, and 12.4% opted for 20-30 mmHg compression stockings, with an average duration of 2.79 (±2 days). After this period, 88.4% used additional compression, with 20-30 mmHg compression stockings (80.9%) and an average duration of 39.3 (±24.0 days). Conclusions Compression therapy is widely employed after thermal ablation of the great saphenous vein. Practice immediately after ablation was divergent, but after the initial phase, the majority of surgeons prescribed additional compression, predominantly using 20-30 mmHg stockings.

ABSTRACT Background Stenosis resulting from neointimal hyperplasia remains a significant concern associated with dysfunction of arteriovenous fistulas (AVF). Objectives To investigate the safety and efficacy of paclitaxel drug-coated balloon (DCB) angioplasty for treating failing AVFs. Methods Investigators analyzed 58 hemodialysis patients treated with RangerTM DCBs from December 2022 to December 2023 across four centers. Lesions treated were de novo or restenotic and located in the juxta-anastomosis, cannulation zone, and outflow segment. Patients were evaluated through physical examinations and Duplex ultrasound at 1, 3, and 6 months. The primary efficacy endpoint was target lesion primary patency at 1, 3, and 6 months, and the primary safety endpoint was freedom from serious adverse events through 30 days post-procedure. Secondary endpoints were access circuit primary patency and technical and procedural success. Results Nine patients (16%) had thrombosed access at the initial presentation, and 31 (53%) presented with recurrent stenosis. The target lesion primary patency rate at 6 months was 85.7%, and the access circuit primary patency rate at 6 months was 67.5%. No serious adverse events, either local or systemic, were reported. Sex, age, stenosis location, type of lesion, presence of thrombosis, lesion recurrence, diabetes status, or whether post-ballooning dilation was performed did not significantly affect the 6-month target lesion primary patency. Conclusions DCB angioplasty was shown to be safe and effective for treating peripheral stenosis in vascular access.

Published: February 2025

ABSTRACT The Pera sweet orange tree is the most cultivated scion variety in Brazil, mainly grafted onto Rangpur lime rootstock. Despite its drought tolerance, Rangpur lime is susceptible to various citrus diseases. More recently, trifoliate orange and its hybrids have been used as alternative rootstocks, but most genotypes are graft-incompatible with Pera. In this study, we assessed the long-term performance of Pera IAC sweet orange, which is a pre-immunized clone against citrus tristeza virus, grafted onto 11 trifoliate orange-derived rootstocks, one somatic hybrid and the standard Rangpur lime. The experiment was installed in Bebedouro, SP, Brazil, in February 2011, in a rainfed regime. The design was completely randomized with 13 treatments, 10 replications and one tree in the plot. Changsha × English Large (IAC 1711) citrandarin rootstock conjugated the tallest trees, high cumulative yield, and good drought tolerance up to 2020, followed by Rangpur lime and tetraploid citranges. The Flying Dragon trifoliate orange and tetraploid Carrizo citrange (IAC 387) rootstocks induced the highest content of soluble solids and acidity in Pera oranges. At 9 years old, four citrandarins, a citradia and one somatic hybrid rootstocks were graft-incompatible with Pera IAC sweet orange. All scion/rootstocks’ combinations were affected by huanglongbing. The IAC 1711 citrandarin, tetraploids Troyer (IAC 385) and Carrizo (IAC 387) citranges and Flying Dragon trifoliate orange have potential as graft-compatible rootstocks of Pera IAC, but evaluations should continue in the long term. In addition, the later rootstock must be evaluated in irrigated high-density orchards aiming at competitive yields.

ABSTRACT This study sought to identify superior genotypes of Coffea arabica and Coffea canephora suitable for agroforestry systems. The experiment took place in two distinct environments: monoculture and an agroforestry system featuring rubber trees (Hevea brasiliensis). Employing a randomized complete block design with four replications, the plants were spaced 3 m apart between rows and 1 m between plants in monoculture. In the agroforestry system, the spacing widened to 8 m between rows and 1 m between plants. The evaluation encompassed 11 genotypes, with 10 plants per plot in monoculture and 18 in the agroforestry system. Thirteen morpho-agronomic characteristics, spanning plant shape, uniformity of maturation, fruit size, vigor, pest and disease resistance, and production, were assessed. Employing the restricted maximum likelihood method and the best unbiased linear prediction method in the Selegen software facilitated data analysis, and selection was executed through the Mulamba-Rank index. Comparative analysis revealed that mean values for the evaluated characteristics were consistently higher in the agroforestry system compared to monoculture. Notably, clones A1, 5V, 308 and LB1 (C. canephora) emerged as the most promising genotypes in agroforestry system. Consequently, these clones stand out as robust candidates for inclusion in the composition of varieties tailored for agroforestry systems. This research offers valuable insights into optimizing coffee cultivation in the context of sustainable agroforestry practices.
Além das galáxias brilhantes: a descoberta da matéria escura e o papel de Vera Rubin
Authors: Medeiros Julia , Ferreira Gabriela Kaiana
Published: February 2025

Desde a década de 1930 os cientistas enfrentavam dificuldades para calcular a massa de aglomerados de galáxias a partir da luminosidade, pois os efeitos gravitacionais observados não correspondiam à soma das massas visíveis. Esse ponto volta a ser uma questão em debate na comunidade científica em função de uma série de estudos ao longo do último século, incluindo os realizados pela astrônoma Vera Rubin e seus colaboradores, que analisaram a rotação de galáxias e observaram que as curvas de velocidades divergiam das previsões teóricas. Atualmente, a explicação mais aceita é de que existe uma entidade, denominada de matéria escura, capaz de interagir apenas gravitacionalmente, que explica a constância das curvas de rotação das galáxias. E, ainda, existe em uma quantidade significativamente maior que a matéria ordinária. Este artigo apresenta uma discussão histórico-epistemológica sobre o processo de construção do conceito de matéria escura e, associado a isso, evidencia a exemplar contribuição de Vera Rubin para a Ciência. Dentre os resultados da pesquisa, foram identificados diversos elementos para análise e interpretação, sob a perspectiva filosófica de Thomas Kuhn. Como bem indicado pela literatura especializada da educação em ciências, esses apontamentos podem contribuir substancialmente para uma maior compreensão da Natureza da Ciência.

ABSTRACT Emitter clogging is the main limitation of drip irrigation systems operating with wastewater. This paper aimed to employ discriminant analysis (DA) to generate classification functions that characterize aquaculture wastewater (AW) dilutions in well water (WA), delivered through non-self-compensating drippers. Five AW dilutions in WA were tested (D1: 100% AW; D2: 75% AW + 25% WA; D3: 50% AW + 50% WA; D4: 25% AW + 75% WA; and D5: 100% WA) to investigate the clogging susceptibility of three non-self-compensating dippers: TS (1.6 L h-1), SL (1.6 L h-1), and NJ (1.7 L h-1) after 160 h of operation. Three hydraulic performance evaluations of the drippers were performed in this period. During the same interval, the quality attributes of the AW dilutions in WA were also quantified. The statistical analyses included correlation matrix and DA. The correlation matrix identified 188 variables with significant correlations. Discriminant functions were constructed for each dripper using DA. These functions revealed Mg2+ as the most significant variable. The classification matrix of these functions achieved a 100% success rate.

Zirconia-toughened alumina (ZTA) is a promising material for dentistry; however, its current formulation exhibits a mauve coloration. This study aimed to synthesize a white ZTA ceramic by doping it with 0.7 wt% magnesium oxide (MgO). Specimens (1.2 mm in thickness x 12 mm in diameter) were divided into 3 groups (n = 15): ZTA doped with chromium oxide (ZTA-Cr2O3), ZTA doped with MgO (ZTA-MgO) and ICE-Zirkon (control group). The materials were analyzed using X-ray diffraction, energy-dispersive X-ray fluorescence spectrometer, scanning electron microscopy, and spectrophotometer. Biaxial flexural strength was conducted, and the Weibull modulus (m) and probability of failure were calculated. ZTA-MgO group had a white color, showing the pattern for alumina and zirconia grains in ZTA with a typical composition of the materials. It demonstrated superior BFS (915 ±41 MPa) and higher reliability than the ZTA-Cr2O3. ZTA-MgO proved to be able to produce white ZTA for future use in dentistry.

Published: February 2025

ABSTRACT Objective: to analyze the potentialities and challenges of developing the Policy for Minimum Price Guarantees for Sociobiodiversity Products (PGPM-Bio) within the context of the State Plan for Bioeconomy of Pará (PlanBio). Theoretical approach: from the perspective of Amartya Sen and his work Development as freedom, the study seeks to examine how PGPM-Bio establishes minimum prices for extractivist products and fosters sustainable development in the region. Method: the research employs a qualitative methodology based on the triangulation of data from national and state legislation related to the bioeconomy, as well as socioeconomic and demographic data analyzed through the lens of Amartya Sen’s capabilities theory. Data analysis was conducted using three main constructs emerging from the literature: public policies, bioeconomy, and minimum prices. Results: the main evidence indicates that the minimum price policy positively impacts the income of extractivist producers and traditional communities, contributing to the conservation of sociobiodiversity and sustainable development in the state of Pará. However, challenges are also anticipated, such as the need for more robust financial resources and policy enhancements to ensure effective implementation. The findings suggest that PGPM-Bio, by guaranteeing minimum prices for extractivist products, contributes to improving the income and quality of life of extractivists, promoting food security and economic inclusion. Conclusions: this research will contribute to the development of more effective public policies and the strengthening of the bioeconomy in the region, fostering social inclusion and environmental conservation.

It is currently subdivided into four subfamilies, and only Delimoideae and Doliocarpoideae have species distributed in the Neotropics, including Brazil and Rio de Janeiro. Six genera occur in Brazil, Curatella, Davilla, Doliocarpus, Neodillenia and Pinzona circumscribed in Doliocarpoideae, and Tetracera representing Delimoideae. According to the latest Brazilian list published, only three threatened species of Dilleniaceae are recognized at the national level, among them is Davilla glaziovii, a species classified as Endangered (EN), endemic to Rio de Janeiro, and the only one occurring exclusively within the limits of the state. With the aim of surveying the Dilleniaceae in the state of Rio de Janeiro, we made field collections in sites of known occurrence of the species, and studied collections in herbaria in person or through online consultations. The occurrence of 16 species of Dilleniaceae was confirmed for the state of Rio de Janeiro. The most species-rich genera are Davilla and Doliocarpus, with six species each, followed by Tetracera, with four species. In addition to Davilla glaziovii, Doliocarpus sessiliflorus and Doliocarpus littoralis are confirmed as endemic to the state of Rio de Janeiro and six other species are classified as threatened.

Resumo Objetivo Identificar o nível de expectativas e satisfação das gestantes com o cuidado de pré-natal. Método Estudo descritivo, transversal, conduzido com 86 gestantes que realizam o acompanhamento de pré-natal em uma Unidade de Estratégia de Saúde da Família da cidade de Natal, Rio Grande do Norte. A coleta de dados ocorreu de novembro de 2022 a fevereiro de 2023, através de um questionário de caracterização de dados sociodemográficos, obstétricos e o instrumento Patient Expectations and Satisfaction with Prenatal Care. A análise foi realizada a partir de estatística descritiva simples. Resultados Participaram da pesquisa 86 gestantes. Foi identificado o predomínio de alta expectativa (34,93) e alta satisfação (72,93). No domínio expectativa, as subescalas “cuidado integral” e “seguimento com o mesmo profissional” tiveram baixa expectativa, enquanto “cuidado personalizado” e “outros serviços” apresentaram alta expectativa. No domínio satisfação, todas as subescalas indicaram satisfação das gestantes. Conclusões e implicações para a prática As expectativas e satisfação das gestantes com relação ao cuidado de pré-natal foram avaliadas positivamente. Contudo, alguns aspectos receberam baixa satisfação, especialmente as características do sistema, como o tempo de espera e as condições da sala de espera. Os resultados deste estudo contribuem para o aperfeiçoamento da assistência em saúde destinada às gestantes.
Well-being aligned with sustainability: contributions of the Brazilian solidarity economy

Abstract The struggle that has taken place in the world of work since the 20th century includes issues relating to decent working conditions and the preservation of nature in defense of a fairer society. The changes that have historically affected work are accompanied by the degradation of environmental and life conditions and are intrinsically linked to broad and immeasurable social precariousness. From the theoretical-practical perspective of Critical Social Psychology, specifically, Social Psychology of Work, in this essay, we intend to present a critical reflection on work and the hegemonic, environmentally unsustainable and socially unfair model of economic development and recognize other ways of operate in life and resist capitalism, patriarchy and colonialism, envisioning possibilities for the solidarity economy to flourish. The problematizations result from the academic trajectory, teaching and work of the authors. Specifically, we revisit a specific study on the Justa Trama agroecological cotton solidarity network, which features female leadership and a broad intercooperation network based on the agroecological cotton production chain, health promotion and environmental sustainability. In the daily interventions and controls that the cooperative members openly promote over the intricacies of the organizational process, actions that promote health and good living can be seen.

Abstract This study aimed to evaluate the performance of the Eta Regional Climate Model in reproducing the seasonal climate over South America for the rainy season from November until April, with emphasis on the Madeira, São Francisco, and Paraná river basins. For this purpose, a 10-year set of 6-month range seasonal hindcasts was produced using the Eta Regional Climate Model at 20-km horizontal resolution driven by the CFSv2 forecasts. In addition to dynamical downscaling, the precipitation and 2-meter temperature were statistically downscaled by applying a Quantile Mapping bias correction. The Eta model forecasts reasonably reproduced the precipitation and temperature patterns in the region, with some errors that were reduced by the statistical downscaling. Precipitation skill scores are higher in the northern and central areas of the continent. Although it has shown mixed performance for extreme events—low in the Paraná basin and limited but useful in the Madeira and São Francisco basins—the dynamical-statistical system developed with the Eta model shows higher skill and added value over the driver model, indicating potential to support water resources management in South America.

Abstract Etlingera elatior is a promising ornamental horticultural species with various purposes such as medicinal, antibacterial agent, culinary, ornamental, and floral arrangement. The increasing demand for more variation has led to the improvements of E. elatior via tissue culture technology. Somaclonal variation helps to overcome the lack of variation of this species due to asexual propagation. The aims of this study are to induce callus and shoot and to detect genetic variations using ISSR markers. The results showed that the Murashige & Skoog (MS) basal medium supplemented with glucose and 1.5 mg L-1 6-benzylaminopurine (BAP) and 3 mg L-1 2,4-dichlorophenoxyacetic acid (2,4-D) produced significantly higher callus percentage, 50% after 20 weeks of culture. The friable calluses were then transferred to shoot induction media containing different concentrations of different BAP, 1-naphthaleneacetic acid (NAA) and thidiazuron (TDZ). After 12 weeks in shoot induction media, a root-like structure was observed in calluses masses T11 (0.1 mg L-1 NAA and 0.3 mg L-1 TDZ). Seven ISSR primers were used to evaluate the genetic variation of calluses. Seventy-two bands were generated, of which 51 bands were polymorphic with an average percentage of polymorphic bands of 72%. Jaccard’s coefficient of similarity values recorded between 0.3529 and 0.4762 exhibited the level of genetic variation among calluses. In short, the explants were affected by different concentrations of auxin and cytokinin for callus induction. ISSR markers revealed the occurrence of genetic variation during callus and shoot induction processes, suggesting a potential to generate new variants using tissue culture.

Authors: Jofré Hugo , Cabezas José Miguel
Published: February 2025

Resumen En el año 2017 se estrenó un nuevo sistema electoral para las elecciones de diputados y senadores de Chile. Este nuevo sistema electoral – con mayor proporcionalidad – reemplazó al sistema electoral binominal, introduciendo nuevos incentivos a la contienda electoral y generando cambios en el sistema político. Luego de dos procesos electorales con este nuevo sistema electoral, las elecciones legislativas de 2017 y 2021, es posible evaluar los efectos de dicha reforma sobre el sistema de partidos. Analizamos la conformación de la cámara de diputados en 4 procesos electorales, dos con el sistema binominal – 2009 y 2013 – y dos con el nuevo sistema. Con una muestra de 3.115 candidatos y 550 diputados electos, medimos el número efectivo de partidos (NEP) y el número efectivo de listas (NEL) del periodo 2009- 2021. Dentro de nuestros hallazgos encontramos un aumento sostenido en la fragmentación del sistema de partidos de Chile, lo que podría conducir a complicaciones para el proceso democrático chileno.

ABSTRACT Objective: To investigate the inclusion of pediatric dentistry in the curricular matrix of dental courses in the state of Rio Grande do Sul, Brazil. Material and Methods: A descriptive exploratory study was conducted. Searches were conducted from the e-MEC systems in December of 2023. The variables of interest were the categorization of the course (public or private), total course load, structuring of the teaching of pediatric dentistry (curricular, elective/optative or extension), course load of pediatric dentistry, number of semesters and nomenclature. Results: There are 28 dental courses in the state (three public and 25 private). Total course load ranged from 4,000 to 4,700 hours and 80% of the courses had ten semesters. Pediatric dentistry is curricular and normally available between the seventh and ninth semesters, with a total hourly load between 120 and 420 hours, generally in two consecutive semesters. Conclusion: The state of Rio Grande do Sul, Brazil, underwent an exponential expansion of dental courses, especially in the form of private schools. The courses follow the national curricular guidelines (NCGs), and pediatric dentistry is a curricular discipline normally offered in the last semesters of the course. Considerable divergence, however, was found in the course load for pediatric dentistry. There is an evident need for the definition of theoretical content and minimum clinical training to enable students to develop skills for treating children.
