1. Whole body vibration in operators using agricultural soil preparation equipment
RESUMO: A utilização de tratores agrícolas tem causado efeitos negativos na saúde do operador. Faz-se necessário que no projeto de uma máquina agrícola sejam levados em consideração fatores humanos, para aumentar a segurança e melhorar a qualidade de trabalho. O objetivo do presente trabalho foi avaliar a transmissibilidade da vibração em equipa

2. REPETITIVE MOTION AND POSTURAL ANALYSIS OF MACHINE OPERATORS IN MECHANIZED WOOD HARVESTING OPERATIONS
ABSTRACT The objective of this study was to evaluate operators’ posture and repetitive motions in the mechanized wood harvesting operations, aiming comfort, safety, and health of forest operators. The study was carried out in the clearcutting of pine stands located in Paraná State, Brazil. Data were obtained in tree cutting operations with feller buncher

3. Cognitive Based Design of a Human Machine Interface for Telenavigation of a Space Rover
ABSTRACT: Human Machine Interface (HMI) design is a critical field of work because no general guidelines or rules have been assessed. In order to aid practitioners to design effective HMIs, different methodologies have been studied. To understand task objectives and plan goal-oriented actions, human operators exploit specific cognitive processes that have to

4. Mechanized methods for harvesting residual biomass from Mediterranean fruit tree cultivations
This study evaluates the technology and work systems used in order to harvest residual biomass from pruning in the specific conditions of Mediterranean fruit orchards (narrow distances between crop-rows). Harvesting has been divided into several types of operations - pruning, biomass alignment between crop tracks, biomass concentration in piles, chipping and

5. Distúrbios osteomusculares relacionados ao trabalho de operadores da colheita florestal mecanizada / Work-related musculoskeletal disorders of operators of mechanized harvesting
The Repetitive Strain Injury / Work Related Musculoskeletal Disorders (LER / DORT) can arise in any field of activity; just there is a causal factor, ie, functions and jobs that expose workers to risk factors. These risk factors are present in the operator of the harvesting machinery activities. Throughout the workday upper limbs are highly required, necessi

6. Mimetic finite difference methods in image processing
We introduce the use of mimetic methods to the imaging community, for the solution of the initial-value problems ubiquitous in the machine vision and image processing and analysis fields. PDE-based image processing and analysis techniques comprise a host of applications such as noise removal and restoration, deblurring and enhancement, segmentation, edge det

7. Análise de similaridades de modelagem no emprego de técnicas conexionistas e evolutivas da inteligência computacional visando à resolução de problemas de otimização combinatorial: estudo de caso - problema do caixeiro viajante. / Similarity analysis for conexionist and evolutionary tecniques of the computational intelligence fild focused on the resolution of combinatorial optimization problems: case study - traveling salesman problem.
An analysis between the Evolutionary Computation and the Neural Computation fields was presented in order to identify similarities and mappings between the theories. In the analysis, the identification of similarities between the models designed for combinatorial optimization problems results in a comparison between the Boltzmann Machine and the Two-Membered

8. BALANCEO DE UN SISTEMA DE COSECHA MECANIZADO UTILIZANDO SIMULACIÓN DE EVENTOS DISCRETOS
ABSTRACT A mechanized harvest system was analysed, working in a radiata pine clear cut operation and compound by a feller buncher, a grapple skidder, a grapple processor and a three-wheeler. A Discrete - Event Simulation Model was built with the goal to balance the system. The mechanized wood processing was the bottleneck according to the time study results,

9. Computação Evolutiva para a Construção de Regras de Conhecimento com Propriedades Específicas / Evolutionary Computing for Knowledge Rule Construction with Specific Properties
Most symbolic machine learning approaches use if-then know-ledge rules as the description language in which the learned knowledge is expressed. The aim of these learners is to find a set of classification rules that can be used to predict new instances that have not been seen by the learner before. However, these sorts of learners take into account the rule

10. Dimensões dos princípios jurídicos na teoria do direito segundo Willis Santiago Guerra Filho: aspectos de uma contribuição brasileira à filosofia do direito contemporânea
The context in which the current discussion is situated about juridical principles and basic rights, central in contemporary theory of the right, is what we intend to show with the Brazilian contribution given by Willis Santiago Gerra Filho, according which, the fenomenology would offer the best preparation for the necessary overcoming of the formalistic pos

11. Entraves institucionais para concessão de auxilio doença acidentario da previdencia social no municipio de Indaiatuba / The institucional hindrances in the path to obtain the concession of the Brazilian National Social Security s accident-compensation, in the Municipality of Indaiatuba
Law nº 8213/91, in article 20, defines occupational disease as the disease acquired or unleashed by the special conditions in which work is done and has a direct relation to it. Once the causal relationship is confirmed, the worker receives compensation from the Brazilian National Social Security System for working disability, which is called accident-compe

12. The Production Process in Mining Sand River in Poti in Teresina - PiauÃ: a look at the Health, Work and Environmental / O processo produtivo na mineraÃÃo de areia no rio Poti em Teresina-PiauÃ: um olhar para a saÃde, o trabalho e o ambiente
This descriptive and cross-sectional survey was designed to evaluate the workersâ health, including occupational risks factors, and the environmental damages caused by sand mining, using hydraulical dredges, on the banks and the riverbed of the Poti river, in Teresina, in Northeast Brazil. Twenty-one dredges were visited, and 18 owners or managers and 75 wo
