De Novo and recurrent thrombotic microangiopathy (TMA) after renal transplantation: current concepts in management
Authors: Abbas Fedaei , Abbas Sara Fedaei
Published: December 2021

Thrombotic microangiopathy (TMA) is a well-recognized complication of kidney transplantation that leads frequently to allograft failure. This serious outcome depends greatly on the underlying etiology as well as the timing of therapeutic interventions. TMA syndromes may occur with no previous history of TMA, i.e., de novo TMA, mostly due to medications or infection, or more frequently recurs after kidney transplantation i.e., recurrent TMA in patients with ESRF due to the atypical hemolytic uremic syndrome (aHUS). On the other hand, patients with shiga-toxin induced HUS (classic HUS), particularly in childhood has a favorable prognosis. One of the fundamental tools of management of this disease is the genetic screening for abnormal mutations, determination of which will recognize the tools of therapy and consequently outcome of the disease to a large extent. While patients with CFH and CFI mutations have a worse prognosis, other patients with MCP mutations-for example- have a more favorable prognosis. Accordingly, plan of therapy can be thoroughly drawn with a better chance of cure. Unfortunately, the successful use of the biological agent “eculizumab”, an anti-C5 agent, in some of these syndromes is largely impeded by its high cost linked to its use as a life-long therapy. However, a new therapeutic option has been recently admitted ameliorating this drawback and improve the cost-effectiveness balance.

Published: December 2021

BACKGROUND

Secondhand smoke exposure (SHSe) is highly prevalent among children and has numerous adverse health effects. Consistent screening for SHSe is an essential first step to helping families break the toxic cycle of smoking.

METHODS

With this quality improvement project, we evaluated a SHSe screening and cessation resource distribution protocol in a general pediatrics inpatient unit of a safety-net hospital. Our primary outcome measure was the percent of admissions screened for SHSe, with a goal of increasing our documented rate of SHSe screening from 0% to 70% within 6 months of implementation. Our secondary outcome measure was the percent of those who screened positive for SHSe who were offered smoking cessation resources. Process measures included tracking nurse confidence in screening and compliance with new workflow training. Balancing measures were nurse satisfaction and brevity of screening.

RESULTS

From May 1, 2019, to April 30, 2020, nurses screened 97.2% of the 394 patients admitted to the pediatric unit for SHSe. Of the patients screened, 15.7% were exposed to cigarettes or other tobacco products, 5.6% to e-cigarettes, and 6.5% to marijuana. Nurses documented offering “Quit Kits” with cessation materials to 45 caregivers (72.6% of positive screen results) and offering 33 referrals to the California Smokers' Helpline (53.2% of positive screen results).

CONCLUSION

In this project, we successfully implemented a screening protocol for SHSe to tobacco, e-cigarettes, and marijuana and a workflow for cessation resource distribution in an inpatient pediatric setting that far exceeded goals. Requiring minimal maintenance and using just a simple paper-based format, the workflow could be adopted at other institutions.
Tensiones entre maternidad y aborto en la obra de Laura Pérez de Oleas Zambrano (Quito, 1959)
Authors: Loza Mayorga Natalia
Published: December 2021

Objetivo: este artículo propone una relectura de la novela Sangre en las manos (1959) de la autora Laura Pérez de Oleas Zambrano, para entender, desde una perspectiva histórica y de género, las tensiones entre maternidad y aborto a través del ejercicio de escritura. Metodología: se analiza la novela de Pérez desde la crítica literaria feminista y los nuevos historicismos. Esto permite entender la novela como un documento cultural que registra las estructuras de poder al mismo tiempo que las transgrede. Originalidad: el análisis de esta obra amplía la discusión sobre la historia de las mujeres en un diálogo interdisciplinario entre historia y literatura que trae al presente una compleja reflexión intelectual sobre la condición femenina desde la maternidad, el aborto y la escritura. Conclusiones: el artículo revela que las tensiones entre maternidad y aborto que surgen en Ecuador en la primera mitad del siglo xx dan cuenta de la centralidad del cuerpo femenino en los discursos públicos de la época; que el rol de la maternidad condiciona la experiencia de ciudadanía de las mujeres y su construcción como sujetos; y que el ejercicio de escritura de Pérez es un acto político que cuestiona la formación del sujeto femenino.
The structural dilemma of value-chain upgrading: Hungarian suppliers' integration into the world economy
Authors: Gerőcs Tamás
Published: December 2021

In the following paper, I examine the considerable impact of the recent world-economic shift that has determined the circumstances of Hungarian suppliers' value-chain integration. I argue that as a result of the specialized positions they occupied in the value-chain after the collapse of the Comecon market, Hungarian enterprises in export-oriented industries faced a dilemma—a trade-off between obtaining the most advanced technologies (and thus access to world-market niches) and retaining ownership in the hands of domestic capital. When company managers opted to protect ownership with the help of the state, they exposed themselves to greater risk of downgrading their position in the value chain. If they managed to get access to advanced technologies (and the requisite funding), they were more likely to lose control over their company's assets, either as a result of a hostile takeover or becoming part of the larger partner's merger-and-acquisition plans. This paper is a discussion of some of the particular characteristics of this dilemma, as well as a comparison with the experience of Hungarian service providers who implemented a different strategy. This paper is also a critical assessment of some of the chief characteristics of the world-economic evolution that has been underway since 2009, such as German automotive value chains' expansion in the CEE region and the growing role of Chinese capital in regional infrastructural projects.
The adoption of industry 4.0 and digitalisation of Hungarian SMEs
Authors: Endrődi-Kovács Viktória , Stukovszky Tamás
Published: December 2021

Hungarian small- and medium-sized enterprises are facing the challenges of digitalisation and innovation to survive fierce competition in the era of Industry 4.0, and particularly of COVID-19. Survival in the heavily hit sectors depends on the degree of digitalisation and involvement in e-commerce. This paper aims to examine Hungarian SMEs’ current scale of digitalisation and adoption of Industry 4.0 technologies. It also analyses the role of the Hungarian government’s support for SMEs’ digital transformation. To this end, secondary data were collected from Eurostat, the European Commission and the Hungarian Central Statistical Office, including the Digital Economy and Society Index (DESI), indices of skills and innovation from SME performance reviews and sectoral business statistics. In processing the data, the study strictly followed the European Commission’ classification protocol, complemented by a qualitative analysis of reports and programmes related to digitalisation and Industry 4.0 in Hungary. The findings reveal that there is a further need for strengthening the digitalisation and innovation capacities of Hungarian SMEs. The effects of introduced measures could not be seen yet. Hence, the Hungarian government should continue to support SMEs’ digital transformation in order to increase their role in high-tech manufacturing and knowledge-intensive services.

The optimum angle of the plates is determined considering aerodynamic, noise and energy aspects and equals 36°.
Analysis of hyperboloid cooling tower projection on 2D shape
Authors: Kwinta Andrzej , Bac-Bronowicz Joanna
Published: December 2021

This paper undertakes the problem of mapping a hyperboloid cooling tower on a single plane. Measurements performed by ground-based laser scanning technology quickly deliver substantial amounts of geometric data of the tower’s outer wall. The essence of the article is projection of the rotational hyperboloid on a plane. The shape of the hyperboloid cooling tower is not directly expandable to a single plane. Mapping a hyperboloid shape on a plane is, therefore, associated with distortions. This paper presents a comparison between cylindrical and conic projection of a hyperboloid cooling tower. The most popular method of mapping hyperboloid is cylindrical projection. The cylinder’s side surface is easily developed on the drawing sheet. For the hyperboloid cooling tower, the biggest distortions occur in the latitudinal direction and reach the highest values at the top and bottom edges. The equation (13) describe distortion for the cylindrical projection. The equation (18) describe distortion for the conical projection. This paper presents results obtained from the performed measurement. The analysis found that cone mapping produces less distortion than cylindrical projection for the hyperboloid cooling tower. We think, that in conical projection, the shape of a hyperboloid cooling tower and theoretical conic shape have better corresponding together than in cylindrical projection.
Determining the volume of soil masses using different measurement techniques
Authors: Kwoczyńska Bogusława
Published: December 2021

Calculating the volume for various types of surfaces and materials is important for many branches of engineering sciences. Correct volume calculation often has a significant impact on the cost and time of a given project. These type of calculations are already applied at the design level. Measurement of cubature is crucial, for example, in construction and mining.
The paper presents an analysis of and calculation results for measuring the volume of soil masses using different measurement techniques, which include: LIDAR (in this case of terrestrial and airborne laser scanning), photos taken with the use of UAV and measurements in the GNSS method. The object of the study was an earth mound located in the Park Dębnicki in Kraków. Relative volume error has been calculated in relation to the terrestrial laser scanning (TLS) method. For each of the tested methods, the error remained within the limits allowed by the standards and amounted to 0.2% for airborne laser scanning (ALS), 2.3% for photos obtained from UAVs and 3.4% for the GNNS-RTK method. The results of tests are presented in graphic and tabular forms. The obtained results were compared and the most advantageous measurement techniques to be used in determining the cubic capacity of this particular research object was indicated.
Energy cluster – an attempt in characterisation and definition
Authors: Gronkowska Joanna
Published: December 2021

Clusters are an organisational and economic phenomenon. This paper attempts to answer what an energy cluster actually is and whether it meets the requirements of a cluster in the classical approach of economic sciences.
The Act of 20 February 2015 on renewable energy sources (Ustawa OZE 2015) introduced the concept of an ‘energy cluster’. It was aimed at, among others, increasing energy security and environmental protection through an efficient use of renewable energy sources. In the literature on the subject, there is no single universally applicable definition of a cluster, it can only be considered in its various aspects. The concept of a cluster has so many applications, associations and meanings that in many respects it has become a ‘chaotic idea’ due to flattening and equalising different types, processes and spatial scales of economic location within one universal concept. However, the main doubt concerns the very definition of a cluster.
p38 regulates the tumor suppressor PDCD4 via the TSC-mTORC1 pathway

Published: December 2021

Programmed cell death protein 4 (PDCD4) exerts critical functions as tumor suppressor and in immune cells to regulate inflammatory processes. The phosphoinositide 3-kinase (PI3K) promotes degradation of PDCD4 via mammalian target of rapamycin complex 1 (mTORC1). However, additional pathways that may regulate PDCD4 expression are largely ill-defined. In this study, we have found that activation of the mitogen-activated protein kinase p38 promoted degradation of PDCD4 in macrophages and fibroblasts. Mechanistically, we identified a pathway from p38 and its substrate MAP kinase-activated protein kinase 2 (MK2) to the tuberous sclerosis complex (TSC) to regulate mTORC1-dependent degradation of PDCD4. Moreover, we provide evidence that TSC1 and TSC2 regulate PDCD4 expression via an additional mechanism independent of mTORC1. These novel data extend our knowledge of how PDCD4 expression is regulated by stress- and nutrient-sensing pathways.
The impact of Economic Policy Uncertainty on the real exchange rate: Evidence from the UK
Authors: Moldovan Paula , Lagoa Sérgio , Mendes Diana
Published: December 2021

The world economy has been punctuated by uncertainty as a result of the 2008 subprime crisis, the European sovereign debt crisis, Brexit, and the 2016 US presidential elections, to mention but a few of the reasons. This study explores how the UK real exchange rate reacts to economic policy uncertainty (EPU) shocks using monthly data for the period 1998 to 2020. We contribute to the literature by identifying the long-run and short-run impacts of EPU using a cointegrated ARDL model, and by studying a country that has been through periods of both relatively low and high uncertainty. Results confirm that EPU has an important effect in the long run by depreciating the exchange rate. In addition to urging policymakers and regulators to concentrate on the sometimes difficult task of keeping policy uncertainty to a minimum as a way of sustaining exchange rate stability and thus promoting long-term economic growth, further evidence is provided on exchange rate fundamentals.
UTOPIAS NA DOCÊNCIA EM HISTÓRIA: DIÁLOGOS COM PROFESSORES FRANCESES
Authors: PACIEVITCH CAROLINE
Published: December 2021

RESUMO: Este texto explora discursos de professores de histoire-géographie sobre a docência em História expressos em editoriais de duas revistas publicadas por associações docentes francesas: Historiens & Géographes e Les Clionautes (1998-2016). Problematizam-se as utopias políticas e educacionais percebidas nesses documentos, a fim de complexificar o olhar sobre os discursos que percorrem a formação de professores de História. Foram selecionados os editoriais que tratavam sobre formação de professores de História, destacando os que, de alguma maneira, expressavam utopias político-educacionais. Utopias são entendidas como narrativas fundadas em crítica ao tempo presente e que projetam futuros melhores, na esteira do Princípio Esperança de Ernst Bloch. A análise permitiu identificar diversas categoriais, sendo que, neste artigo, o foco é na didática e no papel da História no futuro dos estudantes. Dialogar com as revistas francesas, escritas por professores de histoire-géographie da educação básica, evidenciou que o foco nas utopias torna pouco importantes as dicotomias entre história e ensino. Conclui-se que, quando professores de História são provocados a falar sobre seus sonhos, perspectivas e responsabilidades profissionais, a atenção se desloca da repetição dos enunciados mais frequentes em direção a outros percursos, sempre inéditos, provocados pelos encontros com os estudantes e a história, na vida da sala de aula.

RESUMO: Os lugares ocupados pelas discussões no currículo dizem muito sobre a intencionalidade e sobre os interesses que circundam os documentos norteadores da educação brasileira. À vista disso, e com base no aporte teórico relacionado ao pensamento complexo e à Educação Ambiental crítica, o presente estudo versa sobre a identificação do lugar ocupado pela formação ambiental na Base Nacional Comum Curricular (BNCC) e na Base Nacional Comum para a formação inicial e continuada de professores da Educação Básica (BNC-Formação). Analisa-se, por meio de estudo documental e à luz da Análise Textual Discursiva, que o que de fato se delineia nos documentos mencionados é um não-lugar para a formação ambiental, convergindo, assim, para o silenciamento dos preceitos da Educação Ambiental crítica na Educação Básica e no Ensino Superior, este último no que diz respeito a cursos de licenciatura. Nesse sentido, os resultados desvelaram que a discussão socioambiental é objeto de generalização na BNCC e de invisibilização na BNC-Formação, demonstrando, desse modo, como tais documentos configuram-se como instrumentalizadores de uma formação reprodutora dos interesses da ordem dominante e do status quo e arraigada ao paradigma simplista e fragmentador da produção do conhecimento, o que impossibilita a percepção crítica e complexa da realidade.

Authors: Lima Neto Vicente de Sousa , Tavares Paulo Roberto Lacerda , Batista Tatiane Lima
Published: December 2021

Resumo As equações IDF são essenciais no gerenciamento, projeto e operação de sistemas hídricos e podem ser obtidas por meio de dados pluviográficos e de dados pluviométricos. Neste trabalho, dados pluviométricos de precipitação máxima diária anual foram coletados da Agência Nacional de águas (ANA) para 31 cidades da mesorregião Sertão Pernambucano. Inicialmente, testes de hipóteses não paramétricos foram aplicados aos dados ao nível de significância de 5%. Em seguida, os dados foram ajustados a distribuições de probabilidade e os parâmetros das equações IDF foram determinados pelo método de desagregação das isozonas e interpolação logarítmica. As intensidades calculadas pelo método das isozonas e as intensidades calculadas pela equação IDF ajustada foram comparadas pelos coeficientes de eficiência (NSE) e o erro padrão de estimativa (EPE) percentual para avaliar o ajuste dos parâmetros. Por fim, as intensidades de equações IDF de dados pluviométricos e de dados pluviográficos foram comparadas a partir de índices estatísticos para algumas cidades. Os resultados revelaram que EPE variou de 2% a 7%, NSE foi acima de 0,98 e os índices estatísticos apresentaram um ótimo desempenho. Portanto, a metodologia de desagregação empregada é uma alternativa viável no ajuste de equações IDF na região estudada.

Resumo A radiação solar é uma variável climatológica amplamente utilizada em estudos climáticos e pode ser mensurada por meio de estações meteorológicas. Devido ao alto custo e difícil manutenção dos equipamentos de mensuração, é possível estimá-la a partir de modelos matemáticos. Assim, o presente estudo objetivou calibrar e validar os parâmetros da equação de ångström-Prescott e de Hargreaves & Samani para realizar a estimativa da radiação solar incidente em Goiânia, Goiás. Dados históricos diários de temperatura máxima (Tmax; °C) e mínima (Tmin; °C), radiação solar incidente (Rs, MJ m-2 dia-1) e duração da insolação (n, h dia-1) da região foram utilizados. Os parâmetros foram calibrados para períodos mensais e sazonais empregando o método dos mínimos quadrados. Os parâmetros estimados foram validados por meio do índice de concordância (d), do coeficiente de correlação (r) e da raiz do erro quadrático médio (RMSE). O parâmetro kRs variou de 0,12 a 0,14 enquanto o parâmetro a variou entre 0,06 e 0,43 e o b de 0,16 a 0,72. As estimativas nos períodos sazonais apresentaram melhor desempenho quando comparadas aos mensais. Os índices obtidos demonstraram boas estimativas para os parâmetros nos períodos sazonais, sendo adequados para estimar a radiação solar no município de Goiânia.

Abstract This study aimed to analyze Fibroblast Growth Factor-2 (FGF-2) levels in the peri-implant crevicular fluid throughout supportive mucositis therapy. Twenty-six participants with Branemark protocol prosthesis were divided into two groups: the control group, characterized by healthy peri-implants, and the mucositis group, presenting a diagnosis of peri-implant mucositis. All participants underwent clinical examination, radiographic analysis, prosthesis removal, and non-invasive peri-implant therapy (mechanical debridement associated with chlorhexidine 0.12%) during a period of 36 days divided into three intervals. Peri-implant crevicular fluid samples were collected at each interval in order to analyze FGF-2 levels by immuno-enzymatic assay. The control and mucositis groups showed difference in keratinized mucosa. The smaller the range of keratinized mucosa the higher susceptibility of peri-implant mucositis. Throughout the treatment intervals, participants were diagnosed in different groups indicating whether or not the non-invasive therapy was able to treat peri-implant mucositis. There was a significant difference of FGF-2 levels between groups, with the higher FGF-2 levels in the control group (p=0.01). After supportive therapy, the mucositis group showed significantly increased FGF-2 levels (p<0.01) compared to initial levels. After 36 days of supportive therapy, there was a reduction of peri-implant mucositis from 70% to 23%. Clinical and laboratory outcomes showed a clear correlation since FGF-2 levels increased after 36 days. It was concluded that the therapy protocol was effective and promoted a regenerative reaction and FGF-2 can be considered a future target for peri-implant mucositis understanding.

Abstract The aims of this in vivo study were to evaluate the effect of bonding with resin-modified glass ionomer cement (RMGIC) and to assess enamel surface roughness before and after the removal of brackets bonded with composite or RMGIC from the maxillary central incisors. Fifteen orthodontic patients were selected for the study. For each patient, the teeth were rinsed and dried, and brackets were bonded with composite (Transbond XT) and RMGIC (Vitremer Core Buildup/Restorative). At the conclusion of orthodontic treatment, their brackets were removed. Dental replicas were made of epoxy resin in initial conditions (before bonded) and after polishing with an aluminum oxide disc system. Adhesive remnant index (ARI) and surface roughness was measured on the dental replicas and data were evaluated statistically by Mann-Whitney and paired t-test, respectively. No bracket debonding occurred during patients’ treatment periods. It was verified that the ARI values of the two maxillary central incisors were similar (p = 0.665). For both bonding materials, the ARI value of 3 was predominant. After polishing, surface roughness was similar in the composite and RMGIC groups (0.245 μm and 0.248 μm, respectively; p = 0.07). In both groups, enamel surface roughness values were significantly lower after polishing compared with the initial condition (p < 0.001). RMGIC promoted efficiency in cementing brackets without fail during treatment; the choice of composite or RMGIC materials was not a factor that influenced the roughness of the enamel surface, however, polishing led to smoother surfaces than those found at the beginning of the treatment.

Abstract The purpose was to evaluate, in vitro, the fracture strength of teeth restored with 0.3- or 0.6-mm-thick occlusal veneers made of Vita Enamic® bonded to enamel or dentin. Fifty third molars were allocated into five groups (n=10): Group C - control (sound teeth); Group 0.3E - 0.3-mm-thick occlusal veneers bonded to enamel; Group 0.6E - 0.6-mm-thick occlusal veneers bonded to enamel; Group 0.3D - 0.3-mm-thick occlusal veneers bonded to dentin; Group 0.6D - 0.6-mm-thick occlusal veneers bonded to dentin. After luting with Single Bond Universal and Filtek Z-100, the samples were subjected to fracture strength test in a universal testing machine. The fractures were classified as irreparable and reparable. Data were analyzed with 2-way and 1-way ANOVA (α=.05) followed by Tukey’s test. The teeth restored with 0.3-mm-thick occlusal veneers (2658 N) achieved significantly higher fracture strength compared to the teeth restored with 0.6-mm-thick occlusal veneers (2070 N) (p=0.017). The teeth restored with occlusal veneers bonded to enamel (2648 N) had significantly higher fracture strength compared to the teeth restored with occlusal veneers bonded to dentin (2049 N) (p=0.015). Group C (3355 N) and Group 0.3E (2965 N) did not differ significantly from each other, being the fracture strength significantly higher than the other groups (p<0.05). The fractures were predominantly reparable. The teeth restored with 0.3-mm-thick occlusal veneers achieved higher fracture strength compared to the teeth restored with 0.6-mm-thick occlusal veneers. The supporting substrate influenced the fracture strength, which was higher for the teeth restored with occlusal veneers bonded to enamel.

Published: December 2021

Abstract Root canal sealers should have optimum adhesion to the root dentin, low cytotoxicity, sufficient radiopacity and high dimensional stability, which depend mainly on their chemical composition. The aims of this study were to evaluate the chemical composition of Syntex (Cerkamed, Stalowa Wola, Poland), Adseal (Meta Biomed, Cheongju-si, Korea), Sealapex (SybronEndo, Scafati, Italy), MTA Fillapex (Angelus, Londrina, Brazil) and GuttaFlow Bioseal (Coltene/Whaledent, Altstätten, Switzerland) and to determine their radiopacity comparatively. Stainless steel molds with an inner diameter of 5 mm and a depth of 2 mm were constructed. Tested root-canal sealers were mixed and poured into the molds. Following setting, digital periapical radiographs of the specimens (n=12) were taken under standard exposure conditions and the mean gray-values of specimens were measured using a computer graphics program. Then the specimens were examined by scanning electron microscopy, and Energy-dispersive X-ray analysis was performed. The data were analyzed using One-way ANOVA followed by Holm-Sidak multi-comparison test (p = 0.05). Sealapex showed higher calcium peak than MTA Fillapex, GuttaFlow Bioseal, Adseal and Syntex sealers. MTA Fillapex contained a highest amount of tungstate. Sealapex presented the highest radiopacity value among the tested materials (p < 0.05), whereas MTA Fillapex was the least radiopaque material (p < 0.05). Each root canal sealer contains different compositions of radiopacifiers including bismuth oxide, calcium tungstate and zirconium oxide. The tested root canal sealers had radiopacity values above the ISO-specified limit. Sealapex was the most radiopaque root canal sealer followed by GuttaFlow Bioseal, Syntex, Adseal and MTA Fillapex.

O que impede a criatividade? Investigando a influência percebida por estudantes do Ensino Fundamental II de barreiras à criatividade para melhorar a simpatia em relação à criatividade na escola
Authors: Beloyianni Vasiliki , Zbainos Dimitrios
Published: December 2021

RESUMO Nos últimos anos, o cultivo da criatividade dos alunos é uma meta amplamente reconhecida da educação moderna. No entanto, várias barreiras impedem a expressão da capacidade criativa dentro do contexto escolar. A influência de muitas barreiras identificadas pela pesquisa pode variar em diferentes contextos culturais, bem como em relação à capacidade criativa individual. A esse respeito, o presente estudo investigou a influência percebida de certas barreiras à criatividade nos alunos do ensino médio grego em termos de gênero e capacidade criativa. Para os propósitos do estudo, 152 jovens adolescentes completaram a versão traduzida do instrumento Barreiras à Criatividade Pessoal (ALENCAR, 1996; MORAIS et al., 2014), enquanto seu potencial criativo foi avaliado pelas escalas gráfico-artísticas do instrumento Avaliação do Potencial Criativo (Evaluation of Creative Potential Battery - EPoC). Os resultados demonstraram que barreiras como falta de tempo e oportunidades, inibição, timidez e falta de motivação foram percebidas pelos participantes como obstáculos comuns que afetam consideravelmente sua criatividade, enquanto a repressão social relatou estar afetando sua criatividade em menor grau. Em geral, as percepções de obstáculos à criatividade não pareciam afetar significativamente o potencial criativo ou o gênero dos alunos. Nesse sentido, a alta influência percebida de inibidores específicos na criatividade refletiu um clima nas escolas gregas que, em geral, parece ter pouca simpatia pela criatividade. Assim, as intervenções para aumentar a criatividade dos alunos devem se concentrar na remoção de tais barreiras e na melhoria do clima escolar.

Abstract The current focus is on the overall pattern of seed storage present in the fragments of the soil of piedmont and alluvial landscapes of the environment. The present study predicted the seed banks of both soils of alluvial and piedmont zones in different ecological conditions and evaluate the potential of seeds in the restoration of both environments. The composition of the seed bank of soil is mainly affected by the alluvial environment and the structure of cleared area shows that more species of germinating annual grasses and growable seeds with the higher total number. Extant vegetation structures have an important role in the diversity of soil seed reservoirs, whose composition corresponded with the openness of the site. When in situ soil seed bank is recruited, it helps to restore only some components of the plant community in an alluvial environment. In our current research, it was confirmed that seed richness was higher in number at lower elevation (alluvial) than that at high elevation (piedmont). Seed richness showed a significant negative correlation with anions, cations, while significantly positive with altitude that suggests the richness pattern of the overall seed bank of the area is influenced by various environmental factors.

ABSTRACT Objective To estimate the prevalence and factors associated with the regular consumption of fruits and vegetables by the civil servants of the Minas Gerais State Judicial System. Methods This is a cross-sectional analytical study, with a representative sample (n=1.005) of the Minas Gerais State Judicial System’s civil servants. The outcome variable “regular fruit and vegetable consumption” refers to fruit and vegetable consumption on five or more days per week. The explanatory variables were divided into three blocks: (1) sociodemographic (gender, age, education, race/skin color; income); (2) health conditions and life habits (chronic diseases, absenteeism due to illness, consumption of alcoholic beverages, smoking, physical activity and nutritional status); and (3) work characteristics and psychosocial factors (weekly workload, position, overtime, use of the electronic Judicial Process, county, psychological demand and control). Hierarchical Poisson regression by blocks was used to analyze potential factors associated with the outcome. Results The prevalence of regular consumption of fruits and vegetables was 55.3%. Associations were found with female gender, income above 12 minimum wages, sufficient physical activity, use of Electronic Judicial Process, while there was a negative association with alcohol abuse. Conclusion Regular consumption of fruit and vegetable among civil servants in the Judiciary was positively associated with female gender, higher incomes and physical activity. The consumption of alcoholic beverages was negatively associated with the outcome. Educational actions and programs aimed at encouraging healthy lifestyle habits are recommended, in order to raise awareness and involve public servants at all stages of the process.

RESUMO Objetivo O objetivo deste estudo foi avaliar o efeito da educação visual no conforto dos pacientes que recebem terapia de hemodiálise. Métodos Foi utilizado um projeto de estudo aleatório em um ambiente controlado. Este estudo foi realizado com 90 pacientes hemodialisados crônicos em dois centros de diálise, sendo que 45 pacientes pertenciam ao grupo de intervenção e os outros 45 pacientes perterciam ao grupo de controle. Formulário de dados do paciente, escala de conforto de hemodiálise - Versão II, escala de controle de fluidos do paciente de hemodiálise, escala de conhecimento dietético e escala de comportamentos dietéticos foram os documentos usados. No grupo de intervenção, foram conduzidas três entrevistas. Na primeira entrevista, a educação visual foi aplicada e reaplicada após 15 dias. No grupo de controle, duas entrevistas foram realizadas e nenhuma intervenção foi feita. Resultados Descobriu-se que o programa de treinamento tem um amplo efeito sobre o conforto e relaxamento físico do paciente, assim como relaxamento psicoespiritual, transcendência psicoespiritual, transcendência ambiental e relaxamento sociocultural. Além disso, foi notado um efeito moderado sobre o alívio físico no grupo de intervenção no terceiro mês. Dessa maneira, foi determinado que o programa de educação visual aplicado teve um amplo efeito no controle de fluidos, conhecimento de dieta e comportamento do grupo de intervenção. Conclusão Verificou-se que a educação visual tem um efeito positivo no estado de conforto, no conhecimento dietético e no comportamento dietético dos pacientes submetidos à terapia de hemodiálise

ABSTRACT Objective To analyze the factors that are associated with the nutritional risk and appetite loss of long-aged older people with two assessment instruments. Methods A cross-sectional and quantitative study was developed in Três Lagoas, a city in the Brazilian state of Mato Grosso do Sul. The household data collection was conducted with 87 long-aged older adults (≥90 years) living in the community. The risk of malnutrition, malnutrition, and the risk of weight loss were the dependent variables, assessed by the Simplified Nutritional Appetite Questionnaire and by the Mini-Nutritional Assessment - Short Form. The association with independent sociodemographic, general health, psychological, cognitive, and physical variables was analyzed using logistic regressions. Results Most of the older adults were female (55.2%), with an average age of 93.3 years, and 1.4 years of schooling. According to the Simplified Nutritional Appetite Questionnaire, 34.5% of the older individuals were at risk of losing weight. As for the results of the Mini-Nutritional Assessment, 19.5% were classified as malnourished, and 39.1% at risk of malnutrition. A greater nutritional risk in both instruments was associated with the individual's poorer self-perceived health, lower calf circumference, and presence of depressive symptoms. The greater the number of medications used, the lower the chance of weight loss. The agreement between the two instruments was low. Conclusion There was an association connecting malnutrition and appetite/weight loss with lower calf circumference, worse self-perceived health status, and presence of depressive symptoms. These results can assist in interventions planning to reduce the nutritional risk and improve the life quality of older adults.

ABSTRACT Objective To investigate the availability and price of fresh and ultra-processed foods in supermarkets before and during the Covid-19 pandemic in a mid-size city in the Brazilian state of Minas Gerais. Methods Ecological and longitudinal study. A proportionate stratified random sampling method was applied to supermarkets in the municipality. To assess the availability, variety, and price of fresh and ultra-processed foods, we applied the Estudo do Ambiente Obesogênico em São Paulo (ESAO, Obesogenic Environment Study in São Paulo, Brazil) Food Store Observation Tool questionnaire and calculated the Healthy Food Store Index. The audits took place from December 2019 to January 2020, and we returned to the establishments in September 2020. Descriptive analyzes, McNemar tests, paired Student's T or Wilcoxon tests were performed using the SPSS software, version 20.0, with a 5% significance level. Results Ten supermarkets were evaluated. The prices of oranges (p=0.012), bananas (p=0.043), apples (p=0.004), and onions (p=0.004) were significantly increased during the time frame. Sugar-free soft drinks (p=0.044), powdered drinks (p=0.032), and corn snacks (p=0.015) showed a greater variety of brands and flavors during the pandemic. The Healthy Food Store Index score was 9.50±0.85 before the pandemic and 9.00±1.15 during it. Conclusion The prices of some fruits and vegetables increased, and supermarkets sold a greater variety of ultra-processed foods. Such findings highlight the importance of assessing the consequences of the Covid-19 pandemic on the food environment.
BIOCAPACITY OF BRAZILIAN BIOMES USING EMERGY ECOLOGICAL FOOTPRINT CONCEPTS

Abstract This work aimed to assess Brazilian biomes’ biocapacity (BC) using concepts of the Emergy Ecological Footprint method. Climate and forest cover data were interpolated using the Kriging method. In 2016, the Brazilian BC was among the largest in the world, 42.11 gha / cap. The biomes’ forest coverage areas were investigated and simulated in two scenarios: optimistic (with 100% forest coverage) and pessimistic (only 10%). The Amazon’s contribution of half the Brazilian BC would reduce by 88% in a pessimistic scenario. The Atlantic Forest contribution was only 1.9% of the national BC, however, in an optimistic scenario, it would increase by 690%. The reduction of deforestation, fires and expansion of areas protected by law are measures that positively impact the BC of the studied biomes. This methodology can be used as an environmental quality indicator as it adheres to the principles of Sustainable Development.
The goals of the National Biodiesel Program: between planning and implementation
Authors: Santana Gean Claudio de Souza
Published: December 2021

Abstract This work evaluated whether the main goals established by the National Program for the Production and Use of Biodiesel (PNPB) were achieved between 2004 and 2018. For this purpose, reports and surveys prepared by public agencies and soybean producers were used. The results reveal that expectations of improvement in living conditions in rural areas stemming from PNPB implementation were frustrated: there were job losses in agricultural occupations, continuity of rural exodus, increase in land concentration, reduction in the contingent of family farmers, non-inclusion of poor family farmers from the North and Northeast regions. Of the original PNPB goals, only the minimum percentage of biodiesel to diesel was achieved satisfactorily, but dependence on imported diesel increased, even with the development of biodiesel production.
How do community responses from global south contribute to climate justice and resilience debate?
Authors: Seleguim Fabiana Barbi
Published: December 2021

Abstract “Towards a just climate change resilience: Developing resilient, anticipatory and inclusive community response” fills an important gap in literature about climate justice and community responses by focusing its lenses in the global south. Designedly, the chapters cover the issue in all the continents where territories and their populations are located in the global south: Brazil and Uruguay (South America), Bangladesh (Asia), Mozambique (Africa) and Solomon Islands (Oceania). The biggest lesson learned from the cases is that strengthening the role of communities and multi-stakeholder coalitions is essential to reduce the injustices and inequalities inherent in anthropogenic climate change, in the face of deforestation, water contamination, declining catches, political instabilities and other economic impacts.
Between crises and insurgencies: the political ecology in defense of shared living

Published: December 2021

Abstract This article offers a review of the recent trajectories of political ecologies as communities of practice and movements for environmental justice, as well as a paradigm of scientific analysis. In this introduction to the 2021 special issue “Decolonial Insurgencies and Emancipatory Horizons: contributions from Political Ecology” of the Ambiente & Sociedade journal, we present a reflection on the contemporary socio-environmental reality, characterized by crises, environmental destruction, and climate emergency, focusing on the role of political ecology as a privileged space to critically discuss the socio-environmental relations that constitute new forms of violent appropriation of nature. Facing the tension of the current context marked by the rise of phenomena such as authoritarianism, climate change denial, and inequality, we highlight the construction of counter-narratives and alternatives that mobilize other horizons of emancipation and living projects through insurgencies and movements that emerge from the protagonism of marginalized populations and struggles for environmental justice.
