Shaped by European influences, the Brazilian urban landscape was marked by the predominant use of exotic species in planted
areas. In the 19th century along the city streets of Rio de Janeiro, trees were planted at a standard distance from each other.
With time, native species began to be used in the urban landscape. Our purpose was to evaluate the utilization of exotic plant
species in the urban landscape of Rio de Janeiro, evaluate the city’s arboreal deficit, and relate its neighborhood arboreal
density to its economic index. Arboreal deficit represents the negative difference between the total number of expected trees
and the observed number in the streets based in the standard distance used in the past. Twenty native and 40 exotic species
were found in the 1701 streets sampled. A high percent of streets did not have any planted trees and the number of trees was
greater in wealthier neighborhoods. The strong prevalence of exotic species is indicative of the negative impact of human
activity on the biota. Since the municipality of Rio de Janeiro harbors forested areas, the risk for dissemination of exotic
species is high. 相似文献

A radiological dispersal device (RDD) is a simple weapon capable of causing human harm, environmental contamination, disruption, area denial, and economic cost. It can affect small, large, or long areas depending on atmospheric stability. The risk of developing a radio‐induced cancer depends on exposure, and an effective response depends upon available timely guidance. This article proposes and demonstrates a convergence of three different capabilities to assess risk and support rapid safe resource efficient response. The three capabilities that are integrated are Hotspot for dispersion, RERF for epidemiological risk, and RESRAD‐RDD for response guidance. The combined methodology supports decisions on risk reduction and resource allocation through work schedules, the designation and composition of response teams, and siting for operations. In the illustrative RDD scenario, the contamination area for sheltering, evacuation, and long‐term public concern was greatest for calm atmospheric conditions, whilst close‐quarter responders faced highest dose rates for neutral atmospheric conditions. Generally, the risks to women responders were found to be significantly greater than for men, and the risks to 20‐year‐old responders were three times that of their 60‐year‐old counterparts for similar exposure. 相似文献

The Project for Schools Modernization taking place in Portugal, with an estimated total investment of 2450 million for the intervention in the first 205 schools, provide the reclassification of 332 secondary schools by 2015. One of the questions we can pose is if the authorities and the teams of architects selected to design these schools considered fundamental for the correctness of architectural barriers within the school and its accessibility the implementation of standards and principles of inclusion of children/teenagers with special needs within their school environment. As most of the projects are already being implemented, the main aim of this paper is to present the outcomes of a comparative analysis and synthesis of six schools located in the northern part of the country. This analysis occurs from the of Participatory Design perspective which appeals to the experience of the disable children to look (or evaluate) the negative and positive factors in terms of physical space, interpreted by inclusive design rules and orientations. Therefore, the evaluation of schools modernization project, and its discussion, is central for the understanding how these children are addressed in projects which are directed at them. 相似文献

The paper presents the development of a cutting tool guide, specifically for the harvest of bamboo. The development was made based on precepts of eco-design and ergonomics, for prioritizing the physical health of the operator and the maintenance of the environment, as well as meet specific requirements of bamboo. The main goal is to spread the use of bamboo as construction material, handicrafts, among others, from a handy, easy assembly and material available tool. 相似文献

Industrial Design encompasses both product development and optimization of production process. In this sense, Ergonomics plays a fundamental role, because its principles, methods and techniques can help operators to carry out their tasks most successfully. A case study carried out in an industry shows that the interaction among Design, Production Engineering and Materials Engineering departments may improve some aspects concerned security, comfort, efficiency and performance. In this process, Ergonomics had shown to be of essential importance to strategic decision making to the improvement of production section. 相似文献

The hospitals mostly have a high level of complexity, diversity of services and, consequently, occupational risks. The tasks of mobilization and manual repositioning of patients may require professional of the physical demands due to the weight or excessive patient dependency, attitudes arising from inadequate to lean on a bed or work in a restricted area, sudden weight change that can occur if a patient loses balance or strength to change the position or while moving. These, among many other factors can cause or aggravate musculoskeletal problems in health care workers. These diseases translate into frequent musculoskeletal complaints, high rates of absenteeism, licenses and problems of prolonged labor, creating a vicious cycle that compromises patient safety and performance of institutions. The literature has suggested the administration of courses on handling and transportation of patients as one of the most important strategies to reduce the incidence of problems in the spine between the worker's healths. An exercise program emphasizing global distension and strength, mainly the posterior chain muscles (dorsal region), held twice a week, combined with an approach to ergonomics can reduce musculoskeletal symptoms and absenteeism in nursing. 相似文献

The environment where everyday activities are developed, these should be appropriate and the individual who will execute them, for greater efficiency of their work and even if you feel safe, comfortable and satisfied when interacting with that space, expending less energy to this interaction. Given this context, this study aims to structure a software with the results obtained in the field, from anthropometric measure to subsidize the furniture industry in manufacturing of furniture, definition work situations, considering the different anthropometric measurements made between 2001 and 2010, using data from this sample of adults aged 18 to 65 years old and children between 6 and 11 years old. It was convenient to make the software with a site, only instead of staying on the Web has been recorded on CD Rom. Tests with the prototype allow navigation through the structure of the software. The data needed to implement the remaining modules were also raised. Issues related to system layout and usability of the interface also were not considered, because it is an initial prototype. 相似文献
