A model for evaluating sustainability applied to two urban cycleways in brasilia

Este artigo propôs um modelo quantitativo usando Dimensões, Características e Indicadores de Sustentabilidade para avaliar a sustentabilidade das ciclovias. O modelo foi aplicado como um estudo de caso a duas ciclovias reais na capital brasileira, Brasília. O processo de seleção de indicadores de sustentabilidade empregou o método Delphi com 9 especialistas seniores da área de transporte e, originalmente, foram identificados 650 indicadores. Estes foram convertidos para fornecer 28 indicadores consolidados. Utilizou-se o método Função Multiatributo Aditiva (Multiattribute Utility Theory) para estabelecer uma hierarquia de dimensões, características e indicadores. Outros nove especialistas definiram níveis de importância e atribuíram pesos a Dimensões, Características e Indicadores. No total, 40 pesos foram atribuídos aos três níveis hierárquicos e o peso final de cada nível foi considerado a média aritmética dos pesos indicados pelos 9 especialistas. Os pesos dos indicadores foram multiplicados pelos pesos de suas respectivas Características e Dimensões, resultando em uma equação para o Índice de Sustentabilidade na forma de uma combinação linear dos pesos com os indicadores. Os usuários das ciclovias analisadas foram entrevistados e atribuíram pontuações a cada um dos indicadores. A partir dessas pontuações, foi possível calcular o indicador de sustentabilidade de cada ciclovia. A ciclovia 2 obteve uma melhor avaliação em relação a ciclovia 1 em todos os cenários de ponderação analisados.This paper proposed a quantitative model using Sustainability Dimensions, Characteristics and Indicators for evaluating the sustainability of cycleways. The model was applied as a case study to two actual cycleways in the Brazilian capital, Brasília. The sustainability indicator selection process employed the Delphi method with 9 senior experts from the field of transportation and originally 650 indicators were identified. These were converted to provide 28 consolidated indicators. Multi-attribute Utility Theory method was used to establish a hierarchy of the Dimensions, Characteristics and Indicators. Nine other experts defined levels of importance and attributed weights to Dimensions, Characteristics and Indicators. 40 weights altogether were attributed to the three hierarchic levels and the final weight for each level was taken to be the arithmetical average of the weights indicated by the 9 experts. The weights of the indicators were multiplied by the weights of their respective Characteristics and Dimensions, resulting in an equation for the Sustainability Index in the form of a linear combination of the weights with the indicators. The users of the analyzed cycleways were interviewed and assigned scores to each of the indicators. From these scores, it was possible to calculate the sustainability indicator of each bicycle path. The cicloway 2 had a better rating compared to cicloway 1 in all weighting scenarios analyzed

The distances covered by basketball referees in a match increase throughout the competition phases, with no change in physiological demand

It is crucial to know the demands on basketball referees, in different match periods (MPs) and phases of competition, for planning referee training and subsequent successful refereeing. To measure and evaluate the distance covered by referees in a match by measuring the number of interruptions, percentage of heart rate (%HR), and blood lactate concentration ([lac]) in different phases of competition and in different MPs. We studied the qualifying (QP), semifinal (SP), and final (FP) phases of a total of 12 matches (four matches in each phase) of the 2009-2010 Brazilian Basketball League. Distance covered, number of match interruptions, and referees' %HR and [lac] were analyzed. We compared the results between competition phases and between MPs (1st MP, 2nd MP, 3rd MP, and 4th MP). Regarding the distances covered, we observed significant differences (P < 0.05) in the 1st, 2nd, and 3rd MPs between the FP and the other two phases (SP and QP) throughout the match, between each phase; in the 4th MP, a significant difference was found when comparing the QP and the other two phases. Comparing the periods within each phase, we found that a greater distance was covered in the 4th MP in relation to the 3rd MP during the FP. No significant differences were found among the remaining variables. The distances covered by referees in a basketball match increase throughout competition phases. This information is essential for planning of training and for the subsequent success of a referee.It is crucial to know the demands on basketball referees, in different match periods (MPs) and phases of competition, for planning referee training and subsequent successful refereeing.

Ergonomic assessment of postal workers´ pain symptoms and musculoskeletal risks related to parcel processing activity for delivery

The parcel delivery activity is carried out all over the world and workers in this sector have suffered from musculoskeletal disorders (MSDs) due to the strong demand for work generated by the recent increase in e-commerce. This study aimed to evaluate postal workers' pain symptoms, movements and identify MSDs risks related to the parcel processing activity for delivery, proposing preventive measures. A sample of thirty-two workers was evaluated with the application of sociodemographic and Nordic questionnaires and electrical bioimpedance. The motion capture sensors were used to evaluate right/left shoulder joints, segment C7-T1 (Cervical) and segment L5- S1 (Lumbar) of three postal workers (percentiles of anthropometric data: 5, 50, and 95) during four real work activities that are part of the parcel processing. The analyzed workers presented musculoskeletal complaints in practically all body regions, with a greater prevalence in shoulders, hands, lower back, and knees. According to the Body Mass Index (BMI), they were on average overweight (27.8 ± 3.7 kg/m2 ). In the movement analysis, we identified risks related to cervical protrusion, anterior trunk flexion, and shoulder flexion, in addition to repetitive movements. In some activities, the higher stature showed an increase in lumbar and cervical anterior flexion. The set of evaluations showed that the activity of processing orders for delivery offers musculoskeletal risks. We identify that ergonomic adaptations are necessary to adapt the heights of the work environment to the statures of the postal workers. Relevance to industry: The activity of processing orders for delivery is carried out practically all over the world generating jobs and income for its employees. Nonetheless, there are still situations of ergonomic disadvantage that can generate musculoskeletal risks. The findings elucidate ergonomic risks and provide useful information for future ergonomic interventions in the postal/delivery workplace environment.ECT -Eaga Charitable Trust(undefined

It can be differentiated through the age of the patients, anatomic location and behavior of the lesion. In this context, this paper reports on the findings of a rare pathology case: juvenile ossifying fibroma, focusing primarily on its clinical, medical imaging and histopathological features characteristics, in order to familiarize the dentist, provide correct diagnosis and the most appropriate treatment

Impacto do desenho da malha viária na mobilidade urbana

The paper analyzes the performance of different street plans to determine which variables are present in each type, as first step to creating a walkability index. Three neighborhoods of Lisbon are used as case studies: (a) Campo de Ourique - with a grid street plan - (b) Graça ”“ with irregular roads - and (c) Telheiras - with a contemporary street plan. It was found that the grid-based street plan has more road homogeneity, a lower straightness index and a higher average integration index. The contemporary street plan performs the worst, while the organic street plan is ranked in the middle.&nbsp;O artigo explora o desempenho de diferentes malhas viárias de modo a apresentar quais variáveis estão mais presentes em cada tipo de malha criando diretrizes para a composição de um índice de caminhabilidade.

Verificou-se que a malha regular apresenta maior homogeneidade viária, menor índice de conversão e maior média de integração, enquanto a malha contemporânea apresentou o pior desempenho e a malha orgânica, por sua vez, uma posição intermediária

Planejamento e gestão do processo de trabalho em saúde: avanços e limites no Subsistema de Atenção à Saúde Indígena do SUS

The Indigenous Health Care Subsystem (SasiSUS), as part of the Brazilian National Health System (SUS), is responsible for health care for indigenous peoples in Brazil. At the local level, the Special Indigenous Health Districts (DSEI) are responsible for managing, planning, and organizing the work process of the multidisciplinary indigenous health teams (EMSI), which provide primary health care for this population. The objective of the study was to analyze how the planning and the management of the EMSI work process occurs. A holistic multiplecase study was carried out, considering seven DSEI as units of analysis. The main source of data used were interviews and, in a complementary way, direct observation. The results indicated that, in general, planning is present in the organization of the teams’ work process, with variations between the DSEI. Carrying out the planned actions was related to the availability of different resources: adequate functioning of the information system and the intra and intersectoral articulation of SasiSUS. As a conclusion, the need to radicalize participation in planning and management, necessary for a coordinated action to guarantee differentiated care and the principles of SUS, was pointed out.O Subsistema de Atenção à Saúde Indígena (SasiSUS), como parte do Sistema Único de Saúde (SUS), é responsável pela atenção à saúde dos povos indígenas do Brasil.

Cenários para a matriz de geração de eletricidade do Ceará em 2050: pt

Based on the worldwide proposition of energy matrix scenarios for 2050, the objective of this article is to present scenarios of electricity generation for Ceará in 2050, showing the participation of sources already used in the state's electric matrix and adding new ones. The article proposes three scenarios: a conservative one, where the present proportion of electricity generation sources of the state is maintained, a transitional one, with 50% of electricity generation from non-renewable sources and the other 50% from renewable sources, and 100% renewable, without the use of fossil or nuclear fuels. Estimates for 2050 in the state are obtained by extrapolating generation data from 2011 to 2017, reaching an estimated 94,775 GWh. In the conservative scenario, it is observed that half of this generation is made by thermoelectric plants and the other half by wind farms. In the transition scenario, dominated by the use of natural gas, the exponential growth of photovoltaic generation stands out. In the 100% renewable scenario, dominated by wind farms, in addition to the similar growth of photovoltaic generation as in the transition scenario, we highlight the use of urban solid waste and solar thermal concentration plants.A partir da proposição de cenários de matrizes energéticas a nível mundial para 2050, o objetivo do presente artigo é apresentar cenários de geração de eletricidade para o estado do Ceará em 2050, mostrando a participação de fontes já usadas na matriz elétrica do estado e acrescentando novas. O artigo propõe três cenários: um conservador, onde é mantida a proporção atual das fontes de geração de eletricidade do estado, um de transição, com 50% da geração de energia elétrica oriunda de fontes não renováveis e os outros 50% provenientes de fontes renováveis, e um 100% renovável, sem o uso de combustíveis fósseis ou nuclear. As estimativas para 2050 no estado são obtidas através de extrapolação de dados de geração de 2011 a 2017, alcançando um valor estimado de 94.775 GWh. No cenário conservador, observa-se que metade dessa geração é realizada por termelétricas e a outra metade por parques eólicos. No cenário de transição, dominado pelo gás natural, destaca-se o crescimento exponencial da geração fotovoltaica. No cenário 100% renovável, dominado por parques eólicos, além do crescimento semelhante da geração fotovoltaica como no cenário de transição, destaca-se a utilização dos resíduos sólidos urbanos e de centrais solar térmicas de concentração

Pervasive gaps in Amazonian ecological research

Biodiversity loss is one of the main challenges of our time,1,2 and attempts to address it require a clear un derstanding of how ecological communities respond to environmental change across time and space.3,4 While the increasing availability of global databases on ecological communities has advanced our knowledge of biodiversity sensitivity to environmental changes,5–7 vast areas of the tropics remain understudied.8–11 In the American tropics, Amazonia stands out as the world’s most diverse rainforest and the primary source of Neotropical biodiversity,12 but it remains among the least known forests in America and is often underrepre sented in biodiversity databases.13–15 To worsen this situation, human-induced modifications16,17 may elim inate pieces of the Amazon’s biodiversity puzzle before we can use them to understand how ecological com munities are responding. To increase generalization and applicability of biodiversity knowledge,18,19 it is thus crucial to reduce biases in ecological research, particularly in regions projected to face the most pronounced environmental changes. We integrate ecological community metadata of 7,694 sampling sites for multiple or ganism groups in a machine learning model framework to map the research probability across the Brazilian Amazonia, while identifying the region’s vulnerability to environmental change. 15%–18% of the most ne glected areas in ecological research are expected to experience severe climate or land use changes by 2050. This means that unless we take immediate action, we will not be able to establish their current status, much less monitor how it is changing and what is being lostinfo:eu-repo/semantics/publishedVersio
