SAÚDE: Direito Assegurado Constitucionalmente
A Constituição Federal almeja a igualdade entre os seres humanos, tratamento igualitário independente de sua origem. Logo, surge o ordenamento social que busca o bem-estar e a justiça social, seus aspectos são regidos com o objetivo de trazer igualdade de condições e condições adequadas às necessidades básicas do ser humano. Concentra-se o referido trabalho na ordem social referente à saúde, um acesso devido a todos e que apresenta um trâmite que, muitas vezes, pode ocasionar sérios danos, devido à lenta marcha da máquina jurisdicional. Assim, tentando-se amenizar sofrimentos maiores, responsabiliza-se o Poder Público vindo desta forma a gerar uma grande discussão de quem seria responsabilidade no fornecimento dos referidos medicamentos

VEER: Um Algoritmo de Seleção de Pares em Redes Ad Hoc Veiculares
National audienceThis paper introduces Veer, a peer selection algorithm for vehicular ad hoc networks running peer-to-peer file exchange applications. Contrary to existing approaches that basically consider vehicular networks as ordinary mobile ad hoc networks, Veer relies on the individual mobility patterns of the vehicles when making peer selection, and this at low control overhead. In Veer, replies are only sent by peers that share part of their trajectories with the requesting node. The file transfer is then scheduled to the time interval when both vehicles meet. In this way, Veer avoids multi-hop file transfers, thus reducing contention areas and increasing the global capacity of the network. We show through extensive simulation that using such an opportunistic one-hop transfer mechanism gives better results than multi-hop file tranfers. In order to support our simulation results, we show through real experiments the capacity of car-to-car links with off-the-shelf hardware
Veer: A Trajectory-Based Peer Selection Algorithm for Networks of Vehicles
International audienceWe propose Veer, a peer selection algorithm for file exchange in vehicular ad hoc networks. The innovative aspect of Veer is that it relies on embedded GPS devices to determine individual mobility patterns and, consequently, to help select the peers that increase the probability that a file transfer succeeds. Transfer opportunities are computed in advance based on an estimation of the contact time window between a node and its selected peers. We show that such an opportunistic one-hop transfer mechanism leads to better results than traditional multi-hop file transfers both in terms of goodput and delivery ratio
Measuring the capacity of in-car to in-car vehicular networks
International audienceA particular class of vehicular networks is the one that includes off-the-shelf end-user equipment (e.g., laptops and PDAs) running from the interior of vehicles: in-car nodes. They are subject to limited communication conditions when compared with nodes specifically designed to this context. Existing works either consider antennas installed on top of the vehicle roof or nodes that operate in infrastructure mode. In this article, we investigate through real experiments the characteristics of links formed by in-car nodes running off-the-shelf wireless technologies such as IEEE 802.11(a/g) in ad hoc mode. We surprisingly observe that in-car nodes do show enough performance in terms of network capacity to be used in a number of applications, such as file transfer in peer-to-peer applications. Nonetheless, we identify some key performance issues and devise a number of configuration recommendations and future work directions
NEOTROPICAL CARNIVORES: a data set on carnivore distribution in the Neotropics
Mammalian carnivores are considered a key group in maintaining ecological health and can indicate potential ecological integrity in landscapes where they occur. Carnivores also hold high conservation value and their habitat requirements can guide management and conservation plans. The order Carnivora has 84 species from 8 families in the Neotropical region: Canidae; Felidae; Mephitidae; Mustelidae; Otariidae; Phocidae; Procyonidae; and Ursidae. Herein, we include published and unpublished data on native terrestrial Neotropical carnivores (Canidae; Felidae; Mephitidae; Mustelidae; Procyonidae; and Ursidae). NEOTROPICAL CARNIVORES is a publicly available data set that includes 99,605 data entries from 35,511 unique georeferenced coordinates. Detection/non-detection and quantitative data were obtained from 1818 to 2018 by researchers, governmental agencies, non-governmental organizations, and private consultants. Data were collected using several methods including camera trapping, museum collections, roadkill, line transect, and opportunistic records. Literature (peer-reviewed and grey literature) from Portuguese, Spanish and English were incorporated in this compilation. Most of the data set consists of detection data entries (n = 79,343; 79.7%) but also includes non-detection data (n = 20,262; 20.3%). Of those, 43.3% also include count data (n = 43,151). The information available in NEOTROPICAL CARNIVORES will contribute to macroecological, ecological, and conservation questions in multiple spatio-temporal perspectives. As carnivores play key roles in trophic interactions, a better understanding of their distribution and habitat requirements are essential to establish conservation management plans and safeguard the future ecological health of Neotropical ecosystems. Our data paper, combined with other large-scale data sets, has great potential to clarify species distribution and related ecological processes within the Neotropics. There are no copyright restrictions and no restriction for using data from this data paper, as long as the data paper is cited as the source of the information used.
