Abordagem da ergonomia para avaliação do treinamento simulado das equipes de resposta à emergência em lançamentos de veículos aeroespaciais

This dissertation introduces a study that aims to analyze the simulated training of emergency teams and proposes recommendations for the current training system in order to improve the collective skills and resilience of these teams when facing possible critical situations, triggered by possible accident occurrences during aerospace vehicle launching operations in the Barreira do Inferno Launch Center in Parnamirim / RN. This is a field, exploratory, descriptive, explanatory, and a case study with a qualitative approach. Therefore, we adopted the ergonomics approach, using the situated method of ergonomic work analysis (AET), combining observational and interactive methods. The relevance of this research is characterized by the contributions to minimize the human and material hazzards resulting from possible accidents in these operations, the scientific contribution of the AET for simulated emergency training analysis in the launching operations of aerospace vehicles - which are complex and involve risk of accidents - and consequently, the scientific contribution to the current process of recovering the Brazilian Space Program. The survey results point to problems of various kinds in the current simulated training system which compromise the safety of the operations. These problems are grouped into four categories: technological, organizational, team training and from the activity itself, regarding more specifically communication and cooperation (among the team members and these ones with other sectors involved in the launching operation) and regarding the coordination of actions. We propose: a) a new training model, from the creation and application of scenarios based on postulated abnormalities, which could simulate real critical situations, in order to train and improve the skills of the emergency response teams especially in terms of communication, coordination and cooperation; b) restructuring and reorganizing the current training system, based on the formal establishment of a managing staff, on the clear division of responsibilities, on the standardization of processes, on the production of management indicators, on the continuous monitoring, on the feedback from trainees about the quality of the training and on the continuing and frequent training of emergency teams.

Caracterização de superfícies seletivas de frequência de periódicas e não-periódicas

The past years have seen a great interest in the use of frequency selective surfaces (FSS), as spatial filters, in many microwave applications. Among these, we highlight applications in telecommunication systems (such as satellite communications and radar), high gain antennas (combined with planar antennas) and (home and industrial) microwave ovens. The FSS is usually composed of two-dimensional periodic arrays, with equally spaced elements, which may be metallic patches (printed on dielectric substrates) or aperture (holes in thin metal surfaces). Using periodic arrays, the FSS have been able to meet the demands of the telecommunications industry. However, new demands are finding technological limitations. In this context, adverse filtering requirements have forced designers to use FSS optimization methods to find specific formats of FSS elements. Another alternative that has been used to increase the selectivity of the FSS is the cascaded FSS, a simple technique that has as main drawback the increased dimensions of the structure, as well as its weight. This work proposes the development of a new class of selective surfaces frequency (FSS) composed of quasi-periodic (or non-periodic) arrangements. The proposed FSS have no array periodicity, in relation with the spatial position of their elements. The frequency responses of these structures were simulated using commercial softwares that implement full-wave methods. For the purpose of validation of this study, FSS prototypes were built and measured, being possible to observe a good agreement between simulated and measured results. The main conclusions of this work are presented, as well as suggestions for future works.

Qualidade de vida no trabalho: o caso de enfermeiros dos Hospitais Públicos Walfredo Gurgel e Santa Catarina

The theoretical foundation of this study addresses the construct Quality of Worklife involving pro-active reading organizations in face to social developments of the working class, which is a challenge to the people s management. In this sense, as a contribution to the studies of quality of worklife (QOWL), this study addresses the quality of lifework of nurses at Walfredo Gurgel and Santa Catarina public hospitals. The goal is to make a diagnosis about the quality of lifework of these employees taking as a basis dimensions and performance indicators shown in the model by Fernandes (1996). The research is characterized by field, in a descriptive way. This survey comprised 75 nurses, with 49 by Walfredo Gurgel hospital and 26 by Santa Catarina one. The data collection was carried out through structured questionnaire. The questions were processed in the software Statistic 6.0, with factor analysis and multiple regressions, after the systematization of data. As a result, the most nurses in hospitals are dissatisfied with the quality of lifework, with the highest incidence in Santa Catarina hospital. The variable occupational health assessment was more negative in the hospital Santa Catarina one, whereas in Walfredo Gurgel, was family assistance. The variable guarantee of employment was more positive assessment in two hospitals without, though, implying in high importance on QOWL of nurses. The factor structure and decision showed greater sensitivity to explain the QOWL of nurses, joining 17 variables from 40 of the model. The factor working conditions, joining 6 variables, showed the second highest sensitivity. The compensation factor, gathering 5 variables, showed the third highest sensitivity while image and health factors showed minor importance

As pessoas na organização e o (re)alinhamento estratégico: o modelo de gestão da Alesat combustíveis em Natal/RN

Este trabalho consiste num estudo de caso na empresa Alesat cujo objetivo geral foi compreender o modelo de gestão de pessoas adotad por uma empresa norteriograndense à luz do modelo estratégico de gestão de pessoas. O estudo baseouse na literatura de Albuquerque (2002); Ashton, Haffenden e Lambert (2004); Fischer (2002); Legge (1995); Mascarenhas (2008); Tanure, Evans e Pucik (2007), Ulrich (2000) e Vasconcelos (2006), dentre outros, paa apreender como os profissionais que atuam no delineamento de estratégias e operacionalização das ações de recursos humanos concebem o seu posicionamento e eventual alinhamento à estratégia organizacional. O método analisou e descreveu o modelo de gestão de pessoas da empresa campo do estudo. A coleta de dados contou com a realização de entrevistas semi-estruturadas com os 05 gestores de RH que atuam na matriz (Natal/RN). Também foram coletados dados secundários, além de documentos e comunicações internas da empresa que tocam ao RH. Os dados coletados foram analisados à luz da análise de conteúdo de Bardin (1977). Através da análise, foi possível identificar políticas e práticas de RH que perpassam um modelo de gestão de pessoas bem definido e consolidado, com impactos mensuráveis no desempenho organizacional. Percebeu-se, também, a forte disseminação de uma cultura organizacional com foco no posicionamento estratégico e na informalidade e proximidade das relações, que permeiam o modelo de gestão de pessoas. Concluiuse a coerência entre as políticas estratégicas da empresa e as de recursos humanos. A pesquisa apreendeu as interfaces do modelo de gestão estratégica de pessoas da empresa; estas implicam uma alternância entre pensamentos e atitudes vinculados à versão hard, onde o papel das prática de RH é garantir que as pessoas alcancem os objetivos empresariais; e à versão soft, onde o papel do RH é desenvolver o capital intelectual e humano para diversificar os negócios e alcançar resultados sustentáveis e diferenciados. O salto qualitativo atingido pela Ale pode ser atribuído ao fato de possuir um RH situado hierarquicamente na alta cúpula da empresa, em posição de consultoria interna o que oferece perspectivas de atuação que vão muito além das rotinas operacionais desenvolvidas por boa parte das empresas no Brasil

Henrique Novaes: técnica, território e cidade em uma trajetória profissional: Brasil, primeira metade do século XX

The career of civil engineer Henrique de Novaes, a remarkable figure in the academic, technical and political fields, demonstrates its extensive and relevant work across Brazil in the first half of the twentieth century. It covered from the design of water supply and sewage works, road and rail transport networks, works against drought in the Northeast, hydroelectric and harbor facilities to the urbanization planning and architectural projects, which displays a systematic and multiple production. City and territory conformed to his fields of verification, practical and above all, transformation. The search for understanding of the inclusion of a social actor in this process thus contributes to the specific analysis of the doings of Henrique de Novaes, who graduated at Polytechnic School of Rio de Janeiro in 1906. From a polymorphic activity in different scales, one tries to figure how, through academic education or professional practice, urban history in Brazil can be told or built. The introduction of technological innovations matched the purposes of planning and urban sprawl, as well as met the specifications of regulation and institutionalization of public infrastructure services at the time. The overall plans proposed by the engineer thought of the city as a whole, interconnected to the structural networks. At the same time, the knowledge of a larger physical scale the territory bounces back in the urban in a relationship of reciprocity and completeness. The objective research, therefore, tries to understand the roles played by Henrique de Novaes s works and academic education in the accomplishment of systematic modernization of Brazilian urban space and territory, recovering a little known historical figure by current historiography. It is proposed, as methodological axis, that the study of this professional career configures itself as an essential element for understanding the idea of progress embodied in the technical studies and proposals for improvements and sanitation nationwide in the first half of the twentieth century . The primary sources for the construction of this analysis were technical articles in journals of the period ( Clube de Engenharia , Viação e Revista Brasileira de Engenharia ), and technical reports, government messages, newspaper articles published at the time, autobiographical reports and the engineer s verbal communications with relatives. The work is structured in three chapters: "Biographical traces, academic education and 'technical and political' activities" illustrates the initiation into the technical, public and political environment; Chapter 2, "Technique and territory" outlines his network understanding through sanitation and transport services; Chapter 3 "Technique and City" describes the influence of polytechnics knowledge on the propositions of modernization of cities; Finally, "Final Thoughts: An Evaluation," presents an overview of the affiliations and practice of an engineer in the different scales, and its contribution to the modernization of Brazilian urban and territorial space
