Representative systematic evaluation studies of the workspace and the extent to which that space is suitable for performing tasks have been developed by professionals engaged on finding evidence as to the importance of users and designers being joint participants in drawing up projects. In this context, this paper sets out to evaluate the environment of a control room in the hydroelectric sector, based on a multidisciplinary method which integrates ergonomics, architecture and environmental psychology so as to assess the influence of space on the user, and thus to identify the user's level of satisfaction with it. It was observed that some adaptation strategies of the space for activities were not implemented satisfactorily, resulting in the need for further studies on making workspaces suitable. 相似文献

This is a research study based on an analysis which sets out to identify and pinpoint ergonomic and usability problems found in a sample of automobile dashboards. The sample consisted of three dashboards, of three different makes and characterized as being a popular model, an average model and a luxury model. The examination was conducted by observation, with the aid of photography, notes and open interview, questionnaires and performing tasks with users, the bases of which are on the principles laid down by methodologies. From this it was possible to point to the existence of problems such as: complaints about the layout, lighting, colors, available area, difficult access to points of interaction, such as buttons, and the difficult nomenclature of dials. Later, the findings and recommendations presented show the need for a further, deeper study, using more accurate tools, a larger sample of users, and an anthropometric study focused on the dashboard, since reading and understanding it have to be done quickly and accurately, and that more attention be given to the study of automobile dashboards, particularly in the most popular vehicles in order to maintain the standards of usability, and drivers' comfort and safety. 相似文献

This paper refers to the comparative study of the equipment used for cooking in commercial of kitchens restaurants that use the system of traditional cooking and those ones which use the system called smart cooking (combination oven). The study investigates the usability issues concerning to the two systems, analyzing comparatively the aspects related to anthropometry, dimensional variables, the use of the product and also the product safety, as well as issues of information related to operation of the new concepts of cooking in intelligent systems. 相似文献

The Ergonomic Work Analysis reports that there are many activities performed by the professional caregivers and that they are exposed to physical and psychological overload. This situation favors the emergence of pain which influences the quality of life in the work place. In this way, the objective of this study was to verify the main postural constraints adopted by caregivers in public day cares. Visits were conducted in 28 day cares aiming at performing an interview to 126 caregivers who have been working for more than 4 years. From the questionnaire it was found that 80% of the participants refer some sort of pain, being 42% in the trunk, 33% in the shoulder and 25% in the lower limbs. The data from OWAS method showed that from the total of 30 postures performed during the work One could see that the main postures adopted by the caregivers were: flexion, lateral inclination and rotation of the trunk and most of the time they are standing. These movements, when bad performed, can lead to injuries in the lower limbs, upper limbs and trunk. It's necessary more attention to these workers.Thought preventive ergonomic actions to reduce pain symptoms and promote a work in health and safety. 相似文献

The Fire Brigade of the State of Rio de Janeiro (CBMERJ) is Brazil's most ancient and is one of the military forces of the state. It has the primary function of activities related to civil defense of the state. This study aims to contribute to the improvement of the current situation by proposing a solution of eliminating totally or at least mitigating risks of ergonomic injury, since all operating activities are based on the performance of man, applying techniques and equipment with intensive use of hands, teamwork, extended shifts and living with stressful situations, which enhance the occurrence of awkward postures among other ergonomic risk factors. This is a quantitative study. The fields of study were five operational units with the highest statistical service of the Corporation. The following items were analyzed: profile of the firemen, work environment, activity performed, adequacy of training received and epidemiological assessment of pain. In total, 208 questionnaires were answered. Data analysis was performed by frequency and presented in tables, charts and graphs. It is important to implement procedures aimed at occupational health and safety of firefighters in the light of ergonomic concepts, so that crews activities are carried out with increased safety and quality. 相似文献

This research deals with the design of leaflets of medicines, evidencing the problems resulting from the lack of Brazilian normalization to promote the use of the graphical representation of instructional texts warnings. It approaches studies related to the effectiveness and efficiency of information systems, highlighting the semiotics and the cultural and informational ergonomics. The analysis of the context uses as method, an analytical study on selected warnings of thirty leaflets of medicines, followed by interviews lead with the public managers involved with the regulation of the pharmaceutical companies, and two experiments with users performed in city of Recife, in State of Pernambuco: one aiming at to identify how they interact with the leaflets of medicines, and the second one testing their understanding concerning standardized illustrations in the United States and the South Africa. The results show the need for improvements in presentation and graphic representation of leaflets of medicines, powering them to the role of communication, to ensure the consumption of medicine safely by its users. The conclusion congregates parameters and recommendations for the graphic representation of warnings in leaflets of medicines in Brazil. 相似文献

In many survival studies, covariates effects are time-varying and there is presence of spatial effects. Dynamic models can
be used to cope with the variations of the effects and spatial components are introduced to handle spatial variation. This
paper proposes a methodology to simultaneously introduce these components into the model. A number of specifications for the
spatial components are considered. Estimation is performed via a Bayesian approach through Markov chain Monte Carlo methods.
Models are compared to assess relevance of their components. Analysis of a real data set is performed, showing the relevance
of both time-varying covariate effects and spatial components. Extensions to the methodology are proposed along with concluding
remarks. 相似文献

Visual attention patterns measured with eye-tracking techniques provide indirect clues about sexual response. This study aimed to test the category specificity of sexual responses to stimuli varying in gender and age by evaluating both early and late attention of gynephilic and androphilic men and women. We simultaneously presented sexually preferred and nonpreferred stimuli and measured time to first fixation and total duration of fixation on four areas of interest: entire body, then face, chest, and pelvis. Androphilic women’s early attention patterns were nonspecific, whereas gynephilic women and both groups of men showed a category-specific pattern for the entire body. In contrast, all groups showed gender-specific patterns of late attention for all areas of interest. We also found support for age specificity of early and late visual attention in all four groups, with greater attention to adult than child stimuli. This study supports the usefulness of a competing stimulus eye-tracking paradigm as a method to examine gender specificity in gynephilic women and androphilic and gynephilic men, and as a measure of age specificity in gynephilic and androphilic men and women. 相似文献

By doing a parallel between old and new reforms on governance issues applied in Latin America, this paper seeks to identify learnings as well as to understand what is new and what is not from this type of policy endeavor. The article focuses on the analysis of the State reforms implemented in Latin America during the 1920s and those of the 1990s. It shows that modernization of public administration follows the State reform; that needs calling for modernization are permanent; and that while ends pursued by the State change in the long run, modernization has to be a permanent activity.
