March or Die: road-killed herpetofauna along BR-040 highway, an ancient road on the Atlantic Forest from Southeastern Brazil / Marche ou Morra: herpetofauna atropelada ao longo da rodovia BR-040, uma antiga estrada na Mata Atlântica do Sudeste do Brasil

Abstract The construction of highways is responsible for access to previously protected areas, resulting in changes in landscape and dynamics of the animal populations that live in these areas. These enterprises are the major responsible for the mortality of wild animals, surpassing hunting and even the trafficking of animals. The objective of this study was to make a list that reflects the diversity of amphibians and reptile's road-killed along the BR-040, a highway that crosses the threaten lowland Atlantic Forest in Southeastern region of Brazil, including the use of microhabitats, lifestyle, activity pattern, reproductive cycles, and possible rare or endangered species. The study area consists of 180,4 km of highways. Monitoring began in 2006 and continues to the present day. A total of 1,410 individuals from 60 species were recorded in this study. The reptiles were more frequent in number of individuals and species. The commonest species recorded were Crotalus durissus and Dipsas mikanii. We have registered a single endangered species: Ranacephala hogei. The highest rates of road-kill were recorded during the wet season. Road-kills of fauna is a major threat to species, studies are of great importance to define plans that seek to mitigate the effects generated by these enterprises.

Resumo A construção de rodovias é responsável pelo acesso a áreas anteriormente protegidas, resultando em alterações na paisagem e na dinâmica das populações animais que vivem nessas áreas. Esses empreendimentos são os maiores responsáveis pela mortalidade de animais silvestres, superando a caça e até mesmo o tráfico de animais. O objetivo deste estudo foi realizar uma lista que reflita a diversidade de anfíbios e répteis atropelados ao longo da BR-040, uma rodovia que atravessa a ameaçada Mata Atlântica na região Sudeste do Brasil, incluindo o uso de microhabitats, estilo de vida, padrão de atividade, ciclos reprodutivos, e possíveis espécies raras ou ameaçadas. A área de estudo é constituída por 180,4 km de rodovias. O monitoramento começou em 2006 e segue até os dias atuais. Ao todo 1.410 indivíduos de 60 espécies foram registrados nesse estudo. Os répteis foram mais frequentes, em número de indivíduos e espécies. As espécies mais comumente registradas foram Crotalus durissus e Dipsas mikanii. Registramos uma espécie ameaçada de extinção: Ranacephala hogei. A maior taxa de atropelamento foi registrada durante a estação chuvosa. O atropelamento de fauna é uma grande ameaça as espécies, sendo de grande importância estudos para definição de planos que busquem mitigar os efeitos gerados por esses empreendimentos.

Negative impacts of mining on Neotropical freshwater fishes

Mining activities have significantly affected the Neotropical freshwater ichthyofauna, the most diverse in the world. However, no study has systematized knowledge on the subject. In this review, we assembled information on the main impacts of mining of crude oil, gold, iron, copper, and bauxite on aquatic ecosystems, emphasizing Neotropical freshwater fishes. The information obtained shows that mining activities generate several different disturbances, mainly via input of crude oil, metals and other pollutants, erosion and siltation, deforestation, and road construction. Mining has resulted in direct and indirect losses of fish diversity in several Neotropical waterbodies. The negative impacts on the ichthyofauna may change the structure of communities, compromise entire food chains, and erode ecosystem services provided by freshwater fishes. Particularly noteworthy is that mining activities (legal and illegal) are widespread in the Neotropics, and often located within or near protected areas. Actions to prevent and mitigate impacts, such as inspection, monitoring, management, and restoration plans, have been cursory or absent. In addition, there is strong political pressure to expand mining; if - or when - this happens, it will increase the potential of the activity to further diminish the diversity of Neotropical freshwater fishes.(AU)

As atividades de mineração têm impactado significativamente a ictiofauna de água doce Neotropical, a mais diversa do mundo. Porém, nenhum estudo sistematizou o conhecimento sobre o assunto. Nesta revisão, reunimos informações sobre os principais impactos da mineração de petróleo, ouro, ferro, cobre, e bauxita sobre os ecossistemas aquáticos, com ênfase nos peixes de água doce Neotropicais. As informações obtidas mostram que as atividades de mineração geram diferentes distúrbios, principalmente por meio de petróleo bruto, metais e outros poluentes, erosão e assoreamento, desmatamento e construção de estradas. A mineração resultou em perda direta e indireta de diversidade de peixes de vários corpos d'água Neotropicais. Os impactos negativos sobre a ictiofauna podem alterar a estrutura das comunidades, comprometer cadeias alimentares inteiras, bem como degradar os serviços ecossistêmicos fornecidos pelos peixes de água doce. Particularmente importante é que as atividades de mineração (legais e ilegais) são generalizadas na região Neotropical, e frequentemente estão localizadas dentro ou perto de áreas protegidas. Ações de prevenção e mitigação de impactos, como planos de fiscalização, monitoramento, manejo e restauração, têm sido precárias ou ausentes. Além disso, há forte pressão política para expandir a mineração; se - ou quando - isso acontecer, aumentará o potencial da atividade em diminuir ainda mais a diversidade de peixes de água doce Neotropicais.(AU)

Mortandad de vertebrados por atropellos en carreteras en Tambogrande, Piura, Perú / Vertebrates road-killed in Tambogrande, Piura, Peru

Resumen Entre los impactos negativos sobre la biodiversidad que causan las obras viales, como las carreteras, se tiene la mortandad de fauna por atropello. En el presente estudio se determina la mortandad de anfibios, reptiles, aves y mamíferos por atropello, en tres carreteras que confluyen en el distrito de Tambogrande (Piura en el norte de Perú) y establecer los sitios de mayor incidencia. Los datos se colectaron entre enero y junio de 2018 en 24 recorridos una vez por semana entre las 7:00 y 14:00 horas. Los recorridos se realizaron sobre una moto lineal a 25 km/h, los datos registrados fueron coordenadas geográficas del punto de atropello principalmente. La mortandad de vertebrados en los transectos se analizó usando el Índice Kilométrico de Abundancia. Los sitios de alta incidencia de atropellos se determinaron con un análisis de densidad de Kernel. Se hallaron 437 animales atropellados pertenecientes a 29 especies. Los animales atropellados más abundantes fueron los mamíferos seguidos de aves, reptiles y anfibios. El IKA promedio fue de 0.2 (IC 95% 0.1 - 0.3) N° de atropellos/Km. Se presentaron 24 puntos de alta incidencia en el área de estudio cercanos entre sí. Utilizando la información de este trabajo se sugiere construir ocho pasos de fauna para vertebrados según estándares internacionales y complementados con señalética adecuada.

Abstract Among the negative impacts on biodiversity caused by road works, such as road and highways, are the killed caused by collisions with vehicles. In this study, the mortality of amphibians, reptiles, birds and mammals by collision with vehicles is determined, on three roads that converge in the Tambogrande district (Piura in northern Peru), and the places with the highest incidence are established. Observations were between January and June of 2018 with a frequency of 24 trips once a week between the hours of 7.00 and 14.00. The trips were taken on a motorcycle at 25 km/h. Geographical coordinates of the point of collisions were recorded. The vertebrates mortality in transects lines was analyzed using the Kilometric Abundance Index (KAI). High incidence places were determined with a Kernel Density Analysis. 437 animals were found dead corresponding to 29 species. The animal group most affected was mammals followed by birds, reptiles and amphibians in that order. The mean KAI was 0.2 (95% CI 0.1 - 0.3) N° of incidences/km. We determinate 24 points of high incidence, they were close to each other. Based in our results, we propose to build eight animal crossing structures for vertebrates complemented with appropriate transit signals.

Falta de atenção ao conduzir veículo automotor como causa de acidentes de trânsito nas rodovias federais brasileiras / Distracted driving of a motor vehicle on Brazilian federal highways as a cause of traffic accidents

RESUMO: Introdução: Falta de atenção ao conduzir (FAC) veículo é tida como fator de risco em ascensão para Acidentes de Transporte Terrestre (ATT). Objetivo: Os objetivos deste estudo foram identificar a tendência do número de vítimas em acidentes por FAC e do número de infrações por uso de aparelho telefônico celular nas rodovias federais brasileiras e problematizar a categoria FAC tal como vem sendo empregada no país. Método: Estudo de séries temporais, com dados de acidentes com vítimas disponibilizados pela Polícia Rodoviária Federal, cuja causa tenha sido FAC, no período de 2007 a 2016, e dados de infrações por dirigir utilizando celular. Resultados: Identificou-se tendência de aumento mensal do número de vítimas de acidentes por FAC no país até meados de 2011 (variação percentual mensal - VPM = 0,57%), seguida de diminuição significante (VPM = -0,45%). As macrorregiões apresentaram comportamento similar, com exceção do Sudeste. Houve tendência de aumento mensal do número de infrações pelo uso de celular pelo condutor de 2007 a 2013. Conclusão: A tendência é de aumento mensal do número de vítimas decorrentes de FAC no Brasil e na maioria das macrorregiões até 2011, com posterior tendência de declínio. A inexatidão da expressão "falta de atenção" compromete a qualidade dos dados e, por consequência, o adequado dimensionamento das vítimas atribuível a esse fator de risco. A díade celular-condução pode estar na origem de acidentes com vítimas por FAC no país.

ABSTRACT: Introduction: Distracted driving (DD) of a motor vehicle is considered an increasing risk factor for land transport accidents. Objective: To identify the tendency in the number of victims in DD accidents and in the number of offences due to cell phone use on Brazilian federal highways, as well as analyze the DD category in depth as it is being used in the country. Method: A time series study with data on accidents with victims, made available by the Federal Highway Police, whose cause was distracted driving, from 2007 to 2016 and data on offences for driving using a cell phone. Results: There was a tendency towards a monthly increase in the number of distracted driving accident victims in the country up to mid-2011 (percentage monthly variation - PMV = 0.57%), followed by a significant decrease (PMV = -0.45%). Macro-regions showed similar behavior, except in the Southeast. There was a monthly increase in the number of offences caused by drivers using cell phones from 2007 to 2013. Conclusion: There was a tendency towards monthly increases in the number of victims of distracted driving in Brazil and in most macro-regions up to 2011, followed by a subsequent downward tendency. The inaccurate nature of the expression "distraction" compromises the quality of the data and, consequently, the adequate estimation of victims attributable to this risk factor. The cell phone-driving dyad could be the root cause of accidents with victims caused by distracted driving in the country.

Estimativa da erosão em carreadores de cana-de-açúcar através da Equação Universal de Perdas de Solo / Estimation of erosion in earth roads of sugar cane using Universal Soil Loss Equation

RESUMO A erosão do solo em carreadores de cana-de-açúcar é um problema que não pode ser desprezado, dado o aumento de área plantada com essa cultura no território brasileiro. No presente artigo, são estimadas as perdas de solo, através do emprego da Equação Universal de Perdas de Solo (EUPS), de quatro trechos de carreadores de cana de uma fazenda no município de Itirapina (SP). Os resultados mostraram estimativas de perdas que variaram de 60,6 a 90,1 t.ha-1 para o tipo de solo Neossolo Quartzarênico.

ABSTRACT Soil erosion in earth roads of sugar cane is a problem that cannot be ignored, given the increase in planted area to this crop in Brazil. In this article soil losses are estimated using the Universal Soil Loss Equation (USLE), at four stretches of sugar cane earth roads of a farm at Itirapina (São Paulo State). Results showed that loss estimates ranged from 60.6 to 90.1 t.ha-1 for typic Quartzipsamment soil.

Tendência do número de vítimas em acidentes de trânsito nas rodovias federais brasileiras antes e depois da Década de Ação pela Segurança no Trânsito / Tendencia del número de víctimas en accidentes de tráfico en carreteras federales brasileñas antes y después de la Década de Acción por la Seguridad en el Tráfico / Trends in the number of traffic accident victims on Brazil's federal highways before and after the start of the Decade of Action for Road Safety

Resumo: O objetivo deste estudo foi analisar a tendência do número de mortos, feridos graves e feridos leves por acidentes de trânsito nas rodovias federais brasileiras, segundo macrorregião, antes e depois do início da Década de Ação pela Segurança no Trânsito (DAST). Trata-se de estudo de séries temporais interrompidas com dados sobre acidentes com vítimas, fatais ou feridas, disponibilizados pela Polícia Rodoviária Federal para o período de 2007 a 2017. Utilizou-se o método de Prais-Winsten para o cálculo da variação percentual mensal (VPM) do número de mortos, feridos graves e feridos leves. Antes da DAST, havia uma tendência de aumento mensal do número de mortos nesses acidentes no país (VPM de 0,71%) e em todas as regiões, com destaque para o Sul (VPM de 1,01%) e Centro-oeste (VPM de 0,84%). Verificou-se tendência inversa após o início da DAST, com diminuição significante no Brasil (VPM de -1,24%) e macrorregiões. Para cada pessoa que morre em um acidente em rodovia federal, há, pelo menos, 12 outras, em média, que sofrem lesões não fatais. Houve tendência de aumento do número de vítimas com ferimentos graves (VPM de 0,53%) e leves (VPM de 0,8%) no Brasil e nas macrorregiões no período que antecedeu a DAST. Após a introdução da DAST, houve uma tendência de diminuição nas frequências absolutas significantes desses desfechos nos níveis nacional e regional. Conclui-se que, antes da DAST, houve tendência de aumento mensal do número de vítimas fatais e feridas por acidentes de trânsito nas rodovias federais. Após o início da DAST, em 2011, observou-se tendência inversa, ou seja, de declínio desses desfechos nos locais estudados.

Abstract: This study aimed to analyze the trend in the number of fatalities, severe injuries, and minor injuries from traffic accidents on Brazil's federal highways according to the country's major geographic regions before and after the start of the Decade of Action for Road Safety (DARS). This was an interrupted time series study of data on accidents with fatal or injured victims provided by the Brazilian Federal Highway Police from 2007 to 2017. The Prais-Winsten method was used to calculate the monthly percentage change (MPC) in the number of fatalities, severe injuries, and minor injuries. Before the DARS, there was an upward monthly trend in the number of fatalities in these accidents in the country as a whole (MPC 0.71%) and in all five regions, especially in the South (MPC 1.01%) and Central-West (MPC 0.84%). There was an inverse trend after the start of the DARS, with a significant decrease in Brazil as a whole (MPC -1.24%) and in the major geographic regions. For each person that dies in an accident on a federal highway, at least 12 others suffer non-fatal injuries. There was an upward trend in the number of victims with severe injuries (MPC 0.53%) and minor injuries (MPC 0.8%) in Brazil and in the major geographic regions in the period prior to the DARS. After the start of the DARS, there was a significant downward trend in the absolute frequencies of these outcomes at the national and regional levels. In conclusion, before the DARS, there was an upward monthly trend in the number of fatal and injured victims of traffic accidents on Brazil's federal highways. After the start of the DARS, in 2011, there was an inverse trend, namely a decline in these outcomes in the country.

Road Traffic Accidents In India: An Overview

Road traffic accidents claim over a million lives every year in the world. As per World Health Organization (WHO) it is one of the leading cause of death. India, being a rapidly developing country with expanding economy has its own issues as regarding road traffic accidents due to rapid proliferation of motorization. Road traffic accidents causes enormous morbidity and mortality and at the same time, the toll on the economy of the country as a result of it is quite heavy. Road traffic accident is a result of an interaction among different factors which include the environ-ment, vehicle and the human being. Traditionally it is considered that road traffic accidents are accidents which are unpredictable, inevitable and not preventable. But road traffic accidents are indeed predictable and preventable in majority of the cases. This require the knowledge of factors contributing and leading to road traffic accidents. There are certain preventive measures which if adopted can lead to decrease in morbidity and mortality resulting from RTA. Hence, it is the responsibility of all to contribute in reducing road traffic accidents.

Factors limiting the Northeast Indian elderly population from seeking cataract surgical treatment: Evidence from Kolasib district, Mizoram, India

Purpose: Reliable data on the barriers to the uptake of cataract surgical services in the Northeast Indian states are scanty. The purpose of this study was to assess the barriers to uptake of cataract surgical services among elderly patients and suggest appropriate strategies to reduce these. Methods: A cross-sectional study was conducted among patients who failed to avail cataract surgical services, 6–12 months' postinitial diagnosis at a community eye health camp. Validated questionnaire was used to collect information through face-to-face interviews at the residence of the participants. Descriptive statistics and Chi-square tests were conducted to assess the association between the barriers quoted and sociodemographic variables. Results: A total of 140 (89.2%) individuals participated in the study, of whom 56 (40%) were aged between 71 and 80 years. The median age for men and women was 73.5 and 72.5 years, respectively. About 57% of participants were female patients. A total of 66 (47.1%) participants had borderline visual acuity followed by those with poor vision (41.4%, n = 58). “Bad roads/difficult terrain” (P = 0.009), “witnessed bad surgical outcomes in others” and “did not feel important” (P < 0.024), “poor overall health status” (P < 0.001), “lack of information” (P = 0.025) and “no escort” (P = 0.025) were significant barriers reported by this population. Conclusion: Most of the barriers reported in this study seem to be endogenous in nature and appear to be within the purview of the local eye care service provider to remedy. Counseling and targeted awareness and information, education, and communication strategies could nullify many of the barriers reported in this study.

New strategies of laparoscopic cholecystectomy from left upper abdomen under massive adhesion of right upper abdomen / 中国内镜杂志

Objective Seen from the laparoscope, there is massive adhesion after the peritonitis, an operation with a large incision or radiation treatment in right upper abdomen. After failing to dissociate the adhesion and create e-nough space with the help of laparoscope, the laparoscopic cholecystectomy from the left upper abdomen is adopted depending on the specific situation to explore the possibility and practicability of creating instrument channel and operating space. Methods From May 2001 to May 2015, 13 patients (with a medical history of peritonitis, an opera-tion with a large incision, serious peritonitis or radiation treatment in right upper abdomen) were received operations of laparoscopic cholecystectomy, adhesion was serious near the trauma or otherwise. During the operation, massive adhesion was found in the right upper abdomen. The conventional LC did not work. Instrument channel and operat-ing space were created from the left upper abdomen through facies inferior hepatis and falciform ligament. LC cost 70 minutes to 155 minutes with an average of 117 minutes. Results LC of 13 patients (with a massive adhesion) from left upper abdomen was successful. In this way, it was easy to create instrument channel and operating space and avoid the massive adhesion. The operations took a longer time without injuring stomach intestines and bile vessel. Conclusion Acquired adhesion's peculiarity is negative correlation with distance, LC from the left upper abdomen through facies inferior hepatis and falciform ligament can be avoided the disassociation of massive adhesion and be created the instrument channel and operating space. The two ways are proved to be effective.

Spatial distribution and contamination assessment of heavy metals in street dust from Camagüey city (Cuba) using X-ray fluorescence / Distribución espacial y estudio de contaminación por metales pesados en polvos urbanos de la ciudad de Camagüey (Cuba) mediante fluorescencia de rayos X

Concentrations of Cr, Co, Ni, Cu, Zn, Pb and Fe in the street dust from Camagüey city were studied by X-ray .uorescence analysis. The mean Cr, Co, Ni, Cu, Zn and Pb contents in the urban dust samples (97 ± 30, 14 ± 2, 35 ± 36, 94 ± 26, 199 ± 87 and 42 ± 29 mg.kg-1 dry weight, respectively) were compared with mean concentrations in other cities around the world. Spatial distribution maps indicated the same behaviour for Cr-Ni and Pb-Zn-Cu, respectively, whereas the spatial distribution of Co differs from other heavy metals. The metal-to-iron normalization, using Cuban average metal soil contents as background, showed that street dusts from Camagüey city are moderately or significantly Zn-Pb enriched in those areas associated with heavy traffic density and metallurgic plant location. However, the calculation of the potential ecological risk index shows that metal content in Camagüey street dust does not represent any risk for the city population.

Se determinan por fluorescencia de rayos X las concentraciones de Cr, Co, Ni, Cu, Zn y Pb en los polvos urbanos de la ciudad de Camagüey. Los contenidos medios de metales pesados en las muestras de polvos urbanos (97 ± 30, 14 ± 2, 35 ± 36, 94 ± 26, 199 ± 87 y 42 ± 29 mg.kg-1 en peso seco respectivamente) son comparados con las concentraciones medias determinadas en otras ciudades del mundo. Los mapas de distribución espacial indican comportamientos similares para Cr-Ni y Pb-Zn-Cu respectivamente, en tanto la distribución espacial de Co difiere del resto de los metales. La normalización a un metal de referencia, empleando como fondo los valores medios de concentraciones de metales pesados cubanos, mostró que los polvos urbanos de la ciudad de Camagüey tienen un enriquecimiento moderado o significativo de Zn y Pb en aquellas áreas que están asociadas a una elevada densidad del tráfico automotor y a la ubicación de plantas metalúrgicas. El cálculo del índice de riesgo ecológico potencial mostró que el contenido de metales pesados en los polvos urbanos de Camagüey no representa riesgo alguno para su población.

Spatial and temporal evolution of family-farming land use in the Tapajós region of the Brazilian Amazon / Evolução espacial e temporal do uso da terra para agricultura familiar na região do Tapajós, Amazônia Brasileira

Pressures on the Brazilian Amazon forest have been accentuated by agricultural activities practiced by families encouraged to settle in this region in the 1970s by the colonization program of the government. The aims of this study were to analyze the temporal and spatial evolution of land cover and land use (LCLU) in the lower Tapajَs region, in the state of Parل. We contrast 11 watersheds that are generally representative of the colonization dynamics in the region. For this purpose, Landsat satellite images from three different years, 1986, 2001, and 2009, were analyzed with Geographic Information Systems. Individual images were subject to an unsupervised classification using the Maximum Likelihood Classification algorithm available on GRASS. The classes retained for the representation of LCLU in this study were: (1) slightly altered old-growth forest, (2) succession forest, (3) crop land and pasture, and (4) bare soil. The analysis and observation of general trends in eleven watersheds shows that LCLU is changing very rapidly. The average deforestation of old-growth forest in all the watersheds was estimated at more than 30% for the period of 1986 to 2009. The local-scale analysis of watersheds reveals the complexity of LCLU, notably in relation to large changes in the temporal and spatial evolution of watersheds. Proximity to the sprawling city of Itaituba is related to the highest rate of deforestation in two watersheds. The opening of roads such as the Transamazonian highway is associated to the second highest rate of deforestation in three watersheds.

As pressões sobre a Floresta Amazônica Brasileira têm sido acentuadas por atividades agrícolas de muitas famílias que foram estimuladas a se estabelecer nessa região durante o Programa de Colonização do Governo Federal, na década de 1970. Os objetivos deste presente estudo foram de analisar a evolução espacial e temporal em termos de mudanças de cobertura da terra e uso da terra (CTUT) na região do baixo Tapajós, no Estado do Pará. Contrastam-se 11 bacias que são geralmente representativas do processo de colonização regional por agricultores familiares, e para tanto imagens de satélite Landsat de três diferentes anos (1986, 2001, e 2009) foram analisadas utilizando-se um Sistema de Informação Geográfica. Imagens individuais não-supervisionadas foram classificadas usando-se GRASS, e o algoritmo de classificação de Probabilidade Máxima, para todos os comprimentos de onda do espectro visível e infravermelho (1 a 5 e 7). As classes retidas para a representação do CTUT nesse estudo foram: (1) floresta primária levemente alterada; (2) floresta de sucessão; (3) terra agricultável e pastagem; e (4) solo nu. A análise e observação de tendências gerais em 11 bacias mostram que o CTUT tem mudado rapidamente. O desmatamento médio de floresta primária em todas as bacias foi estimado em mais de 30% no período de 1986 a 2009. A análise em escala local de bacias revela a complexidade do CTUT, notavelmente em relação a grandes mudanças na evolução espacial e temporal das bacias. A proximidade com a cidade de Itaituba, que se encontra em plena expansão, está relacionada com a maior taxa de desmatamento em duas bacias hidrográficas, ao passo que a abertura de estradas, como a Rodovia Transamazônica, está associada à segunda maior taxa de desmatamento em três bacias hidrográficas.

Association between light absorption measurements of PM2.5 and distance from heavy traffic roads in the Mexico City metropolitan area / Asociación entre las mediciones de PM2.5 por absorbancia y la distancia a vías de alto tráfico en la zona metropolitana de la Ciudad de México

OBJECTIVE: To study the relationship between light absorption measurements of PM2.5 at various distances from heavy traffic roads and diesel vehicle counts in Mexico City. MATERIALS AND METHODS: PM2.5 samples were obtained from June 2003-June 2005 in three MCMA regions. Light absorption (b abs) in a subset of PM2.5 samples was determined. We evaluated the effect of distance and diesel vehicle counts to heavy traffic roads on PM2.5 b abs using generalized estimating equation models. RESULTS: Median PM2.5 b abs measurements significantly decrease as distance from heavy traffic roads increases (p<0.002); levels decreased by 7% (CI95% 0.9-14) for each 100 additional meters from heavy traffic roads. Our model predicts that PM2.5 b abs measurements would increase by 20% (CI95% 3-38) as the hourly heavy diesel vehicle count increases by 150 per hour. CONCLUSION: PM2.5 b abs measurements are significantly associated with distance from motorways and traffic density and therefore can be used to assess human exposure to traffic-related emissions.

OBJETIVO: Evaluar la relación entre las mediciones de absorción de luz de las PM2.5 a diferentes distancias de vías de tráfico y el aforo vehicular de diesel en la Ciudad de México. MATERIAL Y MÉTODOS: Se realizaron mediciones de PM2.5 y su análisis de b abs en tres zonas de la Ciudad de México. Se usaron modelos GEE para evaluar el efecto de la distancia y el aforo vehicular de tráfico pesado sobre PM2.5 b abs. RESULTADOS: Se observó una tendencia decreciente en la mediana de PM2.5 b abs conforme se incrementó la distancia a las avenidas de alto tráfico (p<0.002); los niveles decrecen en 7% (CI95% 0.9-14) por cada 100 metros de incremento. Las mediciones de PM2.5 b abs se incrementan en 20% (CI95% 3-38) cuando el aforo vehicular a diesel es mayor de 150 en una hora. CONCLUSIONES: Las mediciones de PM2.5 b abs están significativamente asociadas con la distancia de avenidas con alto tránsito vehicular y con vehículos de diesel.

Factores asociados al trauma fatal en motociclistas en Medellín, 2005-2008 / Factors associated with fatal trauma in Medellín (Colombia) motorcyclists

Introducción. En medio de un cambio en la movilidad vial, en el que la motocicleta se ha generalizado como herramienta de transporte y de trabajo, se da el trauma en motociclistas que genera consecuencias desfavorables para la salud pública, por lo que el conocimiento de sus factores asociados sirve de base para formular estrategias de prevención. Objetivo. Describir las características de persona, tiempo, lugar, vehículo y circunstancias de los accidentes de tránsito en motociclistas y explorar su asociación con trauma fatal en Medellín entre 2005 y 2008. Materiales y métodos. Se hizo un estudio transversal con análisis de caso y controles de datos retrospectivos de la población de la Secretaría de Transporte y Tránsito y de la Secretaría de Salud. Se analizaron 24.062 registros de motociclistas lesionados y 345 fallecidos. Se calculó la razón de momios (odds ratio, OR) (IC95%) para explorar la asociación entre el trauma fatal y las características de exposición, y la OR ajustada (IC95%) mediante un análisis de regresión logística. Resultados. Se encontró una fuerte asociación entre el trauma fatal en motociclistas y el choque contra objeto fijo. Hay mayores posibilidades de morir en los tramos de vía y vías diferentes a intersección o glorieta, vías de dos carriles, en las comunas Robledo, Aranjuez y Guayabal. Los hombres y motociclistas entre 20 y 30 años, entre 40 y 49, y los mayores 50 años, tienen mayores posibilidades de morir e, igualmente, cuando conducen motocicletas de modelo anterior a 1991, o conducen en la madrugada o en horas de alta densidad vehicular. Conclusiones. En Medellín, los motociclistas son un grupo de interés en el sistema vial; por su mayor exposición, la energía que acumulan en los choques contra un objeto fijo es mucho mayor y más letal que la acumulada en otra clase de accidentes, y aunque hay más accidentes de tránsito en glorietas e intersecciones, la mayor posibilidad de morir se presenta en los tramos de vía de doble carril y en otras vías.

Introduction. Motorcycles have come into widespread use as mode of transport and commuting to work. Given the degree of trauma occurring in motorcycle accidents, this increased use has generated adverse consequences for public health. Categorization of factors associated with these events can form the basis for prevention strategies. Objective. The characteristics of person, time, place, vehicle and circumstances of occurrence were described for motorcycle accidents involving rider injury, and the associations were explored with fatal trauma in the city of Medellín, Colombia, in 2005-2008. Materials and methods. A cross-sectional case-control retrospective study was conducted based on population data from the Secretaría de Transporte y Tránsito and Secretaría de Salud. Records were analyzed of incidents involving 24,062 injuries and 345 fatalities. The odds ratio statistic (95% CI) was used to detect significant associations between fatalies and characteristics of trauma exposure; adjusted ORs (95% CI) were obtained by logistic regression analysis. Results. A strong association emerged between fatal trauma and collision with a fixed object. There is a greater chance of dying at railroad crossings, approaches to intersections or roundabouts, and (in the districts of Robledo, Aranjuez and Guayabal) two lane roads. Males, motorcyclists between 20-30 yrs, between 40 and 49 yrs, and >50 yrs were more likely to die. Motorcycle models prior to 1991, travel in early morning hours, or periods of high vehicular density were additional factors of high association. Conclusions. Because motorcyclists have greater exposure, crashes against fixed objects were much more lethal than in other kinds of events. Although an increased mortality occurred at roundabouts and intersections, a greater mortalities occurred at railroad crossings in the sections of single-rail, double-rail and other configurations.

Seguridad vial y peatonal: una aproximación teórica desde la política pública: [revisión] / Road and pedestrian’s security: a theoretical approach from public politics: [review] / Segurança vial e do pedestre: uma aproximação teórica desde a politica pública: [revisão]

Introducción: la seguridad vial se constituye en una de las grandes preocupaciones de los países donde, por los procesos acelerados de desarrollo y expansión de las ciudades, sobresalen los vehículos sobre los peatones. Objetivo: analizar el despliegue de los elementos que involucran el componente teórico y de políticas públicas en el accionar de esfuerzos conjuntos, para reconocer la articulación de los diferentes actores de la sociedad involucrados en la problemática. Materiales y métodos: se revisaron exhaustivamente las bases de datos de Proquest, Hinari, Ovid, Lilacs, Medline y el índice bibliográfico de Scielo. Se acopió una lista de palabras clave relacionadas con el tema motivo de la revisión e incluidas en la ventana de observación desde la década de los 60 hasta la actualidad; se captaron aproximadamente 35 publicaciones que reunían los requerimientos del caso. Resultados: se evidencia desde los años 60 la sinergia de la triada del componente humano, el entorno medioambiental y el relacionado con los vehículos para explicar la génesis de los accidentes viales. Un cuarto elemento es el concepto de exposición, definido como la probabilidad de que se presente un evento de acuerdo con la distancia recorrida; además, está la concepción poblacional y el análisis de la accidentalidad vial desde la visión holística, y la necesidad de incluir el componente del consenso o pacto social. Las políticas públicas de seguridad vial han tratado el concepto de cultura ciudadana como el proceso de los ciudadanos para comprender reglas y normas de forma voluntaria, con el fin de lograr niveles de convivencia ciudadana. Conclusiones: plantear las políticas públicas de seguridad vial y peatonal incluyentes e integrales que amplíen el enfoque conductual humano, de exposición y de factores ambientales a un enfoque poblacional, de cultura ciudadana y de visión social del riesgo. Es necesario pensar lo público desde los pactos sociales establecidos con políticos y entes gubernamentales, en el contexto local y municipal, con el fin de que se logre la concordancia con los elementos que lo componen.

Introduction: road security constitutes a great worry in those countries where, because of the accelerated city development and expansion processes, cars exceed pedestrians. Objective: To analyze the display of the elements that involve the theoretical and public policies component in the activation of joint efforts to recognize the articulation of different society actors involved in the problem. Materials and method: Proquest, Hinari, Ovid, Lilacs, Medline y the Scielo bibliographic index were exhaustedly reviewed. A list of keywords related to the topic which motivated this review which have been included in the observation window since the decade of the 60’s to date. Approximately 35 publications were captured which met the case requirements. Results: It is evident since the 60’s the synergy of the triad: human component, environment setting and that related to the vehicles to explain the genesis of road accidents. A fourth element is the exposure concept defined as the probability to have an event depending on the distance traveled; besides, there is the population conception and the road accident frequency analysis from the holistic view and the need to include the consensus or social pact component. The road security public policies have dealt with the concept of citizen culture as the process through which citizens understand rules and regulations in a voluntary way in order to reach the levels of citizen coexistence. Conclusions: It is necessary to propose road and pedestrian inclusive, comprehensive, security policies that widen the human behavioral environmental factor approach towards a population, citizen culture, and social risk view approach. It is necessary to think the public aspect from the social pacts established with politicians and governmental entities in the local and municipal contexts in order to achieve concordance with the elements that constitute it.

Objetivos. Comparar los niveles de cansancio, somnolencia y sus repercusiones entre conductores formales e informales de ómnibus interprovinciales. Evaluar las condiciones laborales en ambos grupos de estudio. Materiales y métodos.Se realizó un estudio transversal comparativo con muestreo no probabilístico. Se incluyó 100 empresas de transporte terrestre, de las cuales 17 fueron formales según registros oficiales del Ministerio de Transportes y Comunicaciones (MTC), asimismo, los conductores se catalogaron como formales o informales. La encuesta incluía un cuestionario y la versión peruana validada de la escala de somnolencia de Epworth. Resultados. Participaron 71 conductores formales y 274 informales, todos fueron varones. De 134 conductores que pertenecían a las empresas formales de acuerdo al MTC, sólo 43 (32%) pertenecen al grupo formal en base a los criterios propuestos. El 48% (34) de los conductores formales y el 43% (118) de los informales duermen menos de siete horas al día. Admitieron haberse accidentado o ôcasi accidentadoõ el 48% (34) de los formales y 135 (49%) informales; el horario más frecuente fue entre la 01.00 y 04.00 horas. La madrugada es el período en que ambos grupos sienten más cansancio. El 44% (30) de los conductores formales y el 54% (144) de informales realizan cinco o más turnos nocturnos por semana. Del total de los entrevistados, el 16% (56) presentaron somnolencia. La asociación con accidentes de tránsito fue similar. Conclusiones. Los niveles de cansancio y somnolencia fueron similares entre conductores formales e informales. Aquellas empresas catalogadas como formales, presentan alto porcentaje de informalidad entre sus conductores.

Objectives. To compare the levels of fatigue, sleepiness and their consequences between formal and informal drivers of interprovincial buses. To evaluate labor conditions between both study groups. Materials and methods. A comparative cross-sectional study was performed with non-probabilistic sampling. 100 companies of land transport were included,out of which 17 were formal according to the official registries of the Ministry of Transport and Communications (MTC), the drivers were also classified as formal or informal. The survey included one questionnaire and a Peruvian validated version of the Epworth sleepiness scale. Results. 71 formal drivers and 274 informal drivers participated, all were males. Out of the 134 drivers that worked for the formal companies according to the MTC, only 43 (32%) belong to the formal group based on the proposed criteria. 48% (34) of the formal drivers and 43% (118) of the informal sleep less than 7 hours a day. 48% (34) of the formal and 49% (135) of the informal admitted having had an accident or "almost" having had it, the most frequent time of the day was between 01.00 and 04.00 in the morning. The dawn is the period in which both groups feel most tired. 44% (30) of the formal drivers and 54% (144) of the informal ones perform 5 or more night shifts per week. Out of the total of interviewed, 16% (56) had sleepiness. The association with road traffic accidents was similar. Conclusions. The fatigue and sleepiness levels were similar between formal and informal drivers. Companies classified as formal, have a high percentage of informality amongst their drivers.

Impact of road network on the structure of a multifunctional forest landscape unit in southern Turkey.

Forest roads have many kinds of direct and indirect effects such as physical, ecological, and socio-economic effects in landscape scale. In this study the relationship between forest road network and the structure of a multifunctionally planned forest landscape, in the south of Turkey was examined. The aim of the study was to determine whether or not the correlation between road network and landscape structure across a gradient of road density, categorical road/no road approach and landscape pattern data from the managed forest landscapes existed. It was concerned with three type polygons that were forest functioning patches, compartments, and stand patches and were associated with higher road density or existing of road network. To quantify the case, it was analyzed whether the spatial structure of forest patches adjacent to roads differs from the spatial structure of forest patches away from roads. GIS was used to integrate quantitative indices of landscape structure. There was little negatively significant relationship between road density and patch area/size, patch perimeter, and shape index of patton index (PI) and no correlation with patch number and Fractal Dimension (FD). The forest road network modified spatial pattern of patch shape through PI values. The road network increased the number of patch and decreased mean patch size. The existence of road network was more effective than topography index appearing of PI and FD in the roaded areas. It was indicated to potential reverse impacts of road network on spatial structure of forest compartments in terms of shape index (FD). Highest proportions of harvestable forest areas fall into roaded areas. The results define that road networks are effective on the spatial structure of forest landscape. The forest road network of study area has all probable ecological impacts of forest roads mentioned in context.

Principais fatores associados à ocorrência de acidentes de trânsito na BR 163, Mato Grosso, Brasil, 2004 / Main factors associated with motor vehicle accidents on Federal Highway 163, Mato Grosso State, Brazil, 2004

O transporte é essencial para o desenvolvimento econômico de Mato Grosso, Brasil, sendo a BR 163 a principal rodovia de escoamento da produção agropecuária da região. Uma das conseqüências desta atividade é a ocorrência de acidentes de trânsito. Com o objetivo de analisar e categorizar os principais fatores associados à ocorrência de acidentes nesta rodovia, foram utilizados dados da Superintendência de Polícia Rodoviária Federal referentes ao ano de 2004. Nos resultados, destacaram-se como fatores associados à maior chance de ocorrência de acidentes com vítimas (com significância estatística): a condição de rolamento regular (OR = 1,89; IC: 1,32-2,70); os acidentes do tipo colisão frontal (OR = 14,14; IC: 8,96-22,32) e atropelamento de pedestre (OR = 35,95; IC: 8,10-159,52); e os fatores contribuintes defeito na via (OR = 4,35; IC: 1,94-9,75) e desobediência à sinalização (OR = 5,69; IC: 2,01-16,12). Conclui-se que para reduzir o problema dos acidentes nesta rodovia é preciso estabelecer medidas de intervenção de caráter global, não focalizando ações somente na modificação do comportamento do condutor e na fiscalização, mas considerando questões regionais e suas dimensões econômicas, sociais e culturais.

Transportation is essential to the economic development of Mato Grosso State, Brazil, and Federal Highway 163 is the main route for marketing regional agricultural produce. One unfortunate consequence of this activity is the occurrence of motor vehicle accidents. With the aim of analyzing and categorizing the main factors associated with motor vehicle accidents on this highway, the current study used data from the Mato Grosso State Division of the Brazilian Federal Highway Patrol for the year 2004. Factors significantly associated with accidents involving casualties were: substandard paving (OR = 1.89; CI: 1.32-2.70); front-end collisions (OR = 14.14; CI: 8.96-22.32); and running over pedestrians (OR = 35.95; CI: 8.10-159.52. Contributing factors included highway maintenance problems (OR = 4.35; CI: 1.94-9.75) and disobeying traffic signs (OR = 5.69; CI: 2.01-16.12). In conclusion, reduction of motor vehicle accidents on this highway requires comprehensive intervention rather than targeting measures only to drivers or highway patrol personnel, but considering regional issues and their economic, social, and cultural dimensions.

Utilização dos recursos naturais por comunidades humanas do Parque Ecoturístico do Guamá, Belém, Pará / Utilization of natural resources by the human communities of the Guamá Ecotouristic Park, Belém, Pará

O trabalho apresenta dados sobre o uso dos recursos naturais por populações humanas em pequenas comunidades (vilas) localizadas no entorno (n = 6) e no interior (n = 1) do Parque Ecoturístico do Guamá (PEG), visando avaliar os impactos sobre a fauna e flora local, ante a implantação de um projeto de infra-estrutura rodoviária local. A metodologia consistiu da aplicação de dois modelos de questionários. Um direcionado a pessoas-chave, como: moradores mais antigos, presidentes de associações, agentes de saúde, etc, e o outro aplicado aleatoriamente aos adultos locais. Buscou-se atingir pelo menos 50 por cento das famílias das pequenas localidades (<10 famílias) e 10-15 por cento no caso de comunidades maiores ( >11 famílias). Em todos os casos é realizado o extrativismo da fauna e flora, principalmente com o objetivo de subsistência. As espécies mais caçadas foram Agouti paca,Dasyprocta agouti,Nasua nasua, Euphractus sexcintus e Hydrochaeris hydrochaeris. A complementação da renda familiar através do comércio de caça sob encomenda é realizada em todas as comunidades estudadas. Frutíferas como Euterpe oleracea Mart., Musa spp e Theobroma cacao foram encontradas em 100 por cento das comunidades (n=7). Plantas medicinais são rotineiramente cultivadas e empregadas. As espécies madeireiras exploradas são utilizadas com o objetivo de produção de carvão, construção de casas e de meios de transporte, predominando o Inga edulis, Virola surinamensis (Rol.) Warb e Simaruba amara (Aubl.). O trabalho discute os resultados sob o aspecto da implantação do projeto viário, oferecendo recomendações para a minimização dos impactos do mesmo sobre a fauna, a flora e o modo tradicional de vida das comunidades.

This work shows data about the use of natural resources by the human population located in (n=1) and around (n=6) the Guamá Ecotouristic Park (GEP), in order to evaluate the impact on the local fauna and flora in view of the project for constructing a road through the park. The methodology utilized in this community study was the application of two different types of questionnaires. One was directed to key persons such as old residents, presidents of associations, health agents, etc., and the other was randomly applied to local adults. We attempted to approach at least 50 percent of the families in the small villages (< 10 families) and 10-15 percent in the larger communities (> 11 families). In all cases, there was flora and fauna extractivism, especially for subsistence. The most hunted species were the Agouti paca, Dasyprocta agouti, Nasua nasua, Euphractus sexcintus and Hidrochaeris hidrochaeris. All the communities studied complement their family income by hunting wildlife on order. Fruit trees such as Euterpe oleracea Mart., Musa spp and the Theobroma cacao were found in 100 percent of the communities (n=7). Medicinal plants are cultivated and used routinely. Timber species such Inga edulis,Virola surinamensis (Rol.) Warb e Simaruba amara (Aubl.) are used for charcoal production, house building and transportation means. We discuss the results relating to construction of the road, and make recommendations for reducing the impact on the fauna, the flora and the traditional livelihood of the communities.
