Trabalho e família: um estudo da interação de papéis com secretários executivos

The balance between the demands of two important spheres of human life, work and family, has become a challenge due to the pressures of the contemporary that is expanding around the difficulties of reconciling these two comínios. In this sense, this research aimed to understand the work-family interaction in the perception of executive secretaries. The analysis approach used was qualitative research, by worrying about a reality that can not be quantified due to the subjectivity of his goal. The data collection technique used was the semistructured interview to twenty executive secretaries, servants of a Federal Institution of Higher Education. For the understanding and interpretation of the data, we used the technique of content analysis. The results of both analyzes identified the existence of conflict as enrichment in this interaction. The time was identified as the largest generator of conflict work. The overload, relationship stress and conflict emerged as elements common to both domains. As main implications of labor disputes, were revealed: problamas health for secretaries and stress. As main implications of family conflicts emerged: motivation for work, lower performance and lack of concentration. The attempt at balance was identified as the strategy most used by secretaries to minimize work-family conflict. The work-family enrichment was seen as resources that contribute to improving the lives of the secretary in both domains. The opportunity to add knowledge was highlighted as enriching element of work and family values ​​as elements enriching family. The support and experience emerged as enrichment items common to both domains. Regarding the implications of enrichment resulting from the interaction of work and family, the more perceived by respondents were: increased knowledge and skills, material and psychological benefits, improved quality of life and personal and professional fulfillment. From the perception of executive secretaries, work and family spheres of human life are essential and complementary, and that help is contrary, however, this relationship is the primary management of conflicts, ie, how the individual sees and manages the negative side of the work-family

A Relação professor-aluno e a afirmação do discente como sujeito do processo projetual: um estudo exploratório sobre a produção do trabalho final de graduação em arquitetura e urbanismo na UFC e na UFRN

This work deals with teacher-student relationship (TSR), held in a very special moment: the semester of graduation of architecture and urbanism, where students prepare the final work called Graduation Final Work (GFW). That is the last stage to obtain the title of architect and urban planner in Brazil. The text discusses this problem in several ways, emphasing the relationship between graduated student and his/her mentors into the consolidation process of the student as an actor of the planning process, here defined as "autonomy". The work is focused on understanding the TSR in order to elucidate its importance for improvement of teaching bases on development of the GFW, more than the relation between curriculum and institution. Related with the exploratory characteristic of this master thesis, methodologically, the field work happened through: (i) observation of mentorship guidance, (ii) interviews, and (iii) application of questionnaires to teachers and students. Participated 10 pairs of student and mentors of two federal university of Northeast: 05 pairs of the Federal University of Ceará (UFC) and 05 pairs of the Federal University of Rio Grande do Norte (UFRN). The results presented the development of the GFW as a difficult process / fearful for students, highlighting the main problem situations: the difficulty in choosing the theme, the super-sizing of the process, students' insecurities, and parental relationship with the supervisor process. Summing up, the work indicates that the students has a limited autonomy on the GFW process, which calls for a revision in order to promote the consolidation of the student autonomy, which must be observed for some positions recognition of the role of each actor in the process of orientation

Estudo da sinterização do aço inox 316L reforçado com 3% Carbeto de Tântalo - TaC

The present work shows a contribution to the studies of development and solid sinterization of a metallic matrix composite MMC that has as starter materials 316L stainless steel atomized with water, and two different Tantalum Carbide TaC powders, with averages crystallite sizes of 13.78 nm and 40.66 nm. Aiming the metallic matrix s density and hardness increase was added different nanometric sizes of TaC by dispersion. The 316L stainless steel is an alloy largely used because it s high resistance to corrosion property. Although, its application is limited by the low wear resistance, consequence of its low hardness. Besides this, it shows low sinterability and it cannot be hardened by thermal treatments traditional methods because of the austenitic structure, face centered cubic, stabilized mainly in nickel presence. Steel samples added with TaC 3% wt (each sample with different type of carbide), following a mechanical milling route using conventional mill for 24 hours. Each one of the resulted samples, as well as the pure steel sample, were compacted at 700 MPa, room temperature, without any addictive, uniaxial tension, using a 5 mm diameter cylindrical mold, and quantity calculated to obtain compacted final average height of 5 mm. Subsequently, were sintered in vacuum atmosphere, temperature of 1290ºC, heating rate of 20ºC/min, using different soaking times of 30 and 60 min and cooled at room temperature. The sintered samples were submitted to density and micro-hardness analysis. The TaC reforced samples showed higher density values and an expressive hardness increase. The complementary analysis in optical microscope, scanning electronic microscope and X ray diffractometer, showed that the TaC, processed form, contributed with the hardness increase, by densification, itself hardness and grains growth control at the metallic matrix, segregating itself to the grain boarders

Sinterização de aço inoxidável reforçado com partículas nanométricas dispersas de carbeto de nióbio - NbC

Metal powder sintering appears to be promising option to achieve new physical and mechanical properties combining raw material with new processing improvements. It interest over many years and continue to gain wide industrial application. Stainless steel is a widely accepted material because high corrosion resistance. However stainless steels have poor sinterability and poor wear resistance due to their low hardness. Metal matrix composite (MMC) combining soft metallic matrix reinforced with carbides or oxides has attracted considerable attention for researchers to improve density and hardness in the bulk material. This thesis focuses on processing 316L stainless steel by addition of 3% wt niobium carbide to control grain growth and improve densification and hardness. The starting powder were water atomized stainless steel manufactured for Höganäs (D 50 = 95.0 μm) and NbC produced in the UFRN and supplied by Aesar Alpha Johnson Matthey Company with medium crystallite size 16.39 nm and 80.35 nm respectively. Samples with addition up to 3% of each NbC were mixed and mechanically milled by 3 routes. The route1 (R1) milled in planetary by 2 hours. The routes 2 (R2) and 3 (R3) milled in a conventional mill by 24 and 48 hours. Each milled samples and pure sample were cold compacted uniaxially in a cylindrical steel die (Ø 5 .0 mm) at 700 MPa, carried out in a vacuum furnace, heated at 1290°C, heating rate 20°C stand by 30 and 60 minutes. The samples containing NbC present higher densities and hardness than those without reinforcement. The results show that nanosized NbC particles precipitate on grain boundary. Thus, promote densification eliminating pores, control grain growth and increase the hardness values

Efeito da moagem de alta energia na microestrutura e nas propriedades magnéticas do compósito wc-10%p.Co

This work a studied the high energy milling effect in microstructure and magnetic properties of the WC-10wt.%Co composite. The composite powders were prepared by mechanical mixed and milled at 2 hours, 100 hours, 200 hours and 300 hours in planetary milling. After this process the composite were compacted in stainless steel die with cylindrical county of 10 mm of diameter, at pressure 200 Mpa and sintered in a resistive furnace in argon atmosphere at 1400 oC for 5 min. The sintered composite were cutted, inlaid, sandpapered, and polished. The microestrutural parameters of the composite was analyzed by X-ray diffraction, scanning electronic microscopy, optical microscopy, hardness, magnetic propriety and Rietveld method analyze. The results shows, with milling time increase the particle size decrease, it possibility minor temperature of sintering. The increase of milling time caused allotropic transformation in cobalt phase and cold welding between particles. The cold welding caused the formation of the particle composite. The X-ray diffraction pattern of composite powders shows the WC peaks intensity decrease with the milling time increase. The X-ray diffraction pattern of the composite sintered samples shows the other phases. The magnetic measurements detected a significant increase in the coercitive field and a decrease in the saturation magnetization with milling time increase. The increase coercitive field it was also verified with decrease grain size with milling time increase. For the composite powders the increase coercitive field it was verified with particle size reduction and saturation magnetization variation is relate with the variation of free cobalt. The Rietveld method analyze shows at milling time increase the mean crystalline size of WC, and Co-cfc phases in composite sintered sample are higher than in composite powders. The mean crystallite size of Co-hc phase in composite powders is higher than in composite sintered sample. The mean lattice strains of WC, Co-hc and Co-cfc phases in composite powders are higher than in composite sintered samples. The cells parameters of the composite powder decrease at milling time increase this effect came from the particle size reduction at milling time increase. In sintered composite the cells parameters is constant with milling time increase

Desenvolvimento e caracterização de um compósito matriz metálica (CMM): aço EUROFER97 reforçado com Carbeto de Tântalo - TaC

Steel is an alloy EUROFER promising for use in nuclear reactors, or in applications where the material is subjected to temperatures up to 550 ° C due to their lower creep resistance under. One way to increase this property, so that the steel work at higher temperatures it is necessary to prevent sliding of its grain boundaries. Factors that influence this slip contours are the morphology of the grains, the angle and speed of the grain boundaries. This speed can be decreased in the presence of a dispersed phase in the material, provided it is fine and homogeneously distributed. In this context, this paper presents the development of a new material metal matrix composite (MMC) which has as starting materials as stainless steel EUROFER 97, and two different kinds of tantalum carbide - TaC, one with average crystallite sizes 13.78 nm synthesized in UFRN and another with 40.66 nm supplied by Aldrich. In order to improve the mechanical properties of metal matrix was added by powder metallurgy, nano-sized particles of the two types of TaC. This paper discusses the effect of dispersion of carbides in the microstructure of sintered parts. Pure steel powders with the addition of 3% TaC UFRN and 3% TaC commercial respectively, were ground in grinding times following: a) 5 hours in the planetary mill for all post b) 8 hours of grinding in the mill Planetary only for steel TaC powders of commercial and c) 24 hours in the conventional ball mill mixing the pure steel milled for 5 hours in the planetary mill with 3% TaC commercial. Each of the resulting particulate samples were cold compacted under a uniaxial pressure of 600MPa, on a cylindrical matrix of 5 mm diameter. Subsequently, the compressed were sintered in a vacuum furnace at temperatures of 1150 to 1250 ° C with an increment of 20 ° C and 10 ° C per minute and maintained at these isotherms for 30, 60 and 120 minutes and cooled to room temperature. The distribution, size and dispersion of steel and composite particles were determined by x-ray diffraction, scanning electron microscopy followed by chemical analysis (EDS). The structures of the sintered bodies were observed by optical microscopy and scanning electron accompanied by EDS beyond the x-ray diffraction. Initial studies sintering the obtained steel EUROFER 97 a positive reply in relation to improvement of the mechanical properties independent of the processing, because it is obtained with sintered microhardness values close to and even greater than 100% of the value obtained for the HV 333.2 pure steel as received in the form of a bar

Compósitos de matriz metálica à base níquel com adição de TaC e NbC produzidos via metalurgia do pó

Carbide reinforced metallic alloys potentially improve some important mechanical properties required for the overall use of important engineering materials such as steel and nickel. Nevertheless, improved performance is achieved not only by composition enhancement but also by adequate processing techniques, such as novel sintering methods in the case of powder metallurgy. The method minimizes energy losses in addition to providing uniform heating during sintering. Thus, the general objective of this study was to evaluate the density, hardness, flexural strength, dilatometric behavior and to analyze the microstructure of metal matrix composites based nickel with addition of carbides of tantalum and / or niobium when sintered in a conventional furnace and Plasma assisted debinding and sintering (PADS). Initially, were defineds best parameters of granulation, screening and mixing procedure. After, mixtures of carbonyl Ni and 5%, 10% and 15 wt.% NbC and TaC were prepared in a Y-type mixer under wet conditions during 60 minutes. The mixtures were then dried and granulated using 1.5 wt. % paraffin diluted in hexane. Granulates were cold pressed under 600 MPa. Paraffin was then removed from the pressed pellets during a pre-sintering process carried out in a tubular furnace at 500 °C during 30 min. The heating rate was 3 ºC/min. The pellets were then sintered using either a plasma assisted reactor or a conventional resistive tubular furnace. For both methods, the heating rate was set to 8 ºC/min up to 1150 °C. The holding time was 60 minutes. The microstructure of the sintered samples was evaluated by SEM. Brinell hardness tests were also carried out. The results revealed that higher density and higher hardness values were observed in the plasma-assisted sintered samples. Hardness increased with the concentration of carbides in the Ni-matrix. The flexural strength also increased by adding the carbides. The decline was larger for the sample with addition of 5% 5% TaC and NbC. In general, compositions containing added carbide 10% showed less porous and more uniform distribution of carbides in the nickel matrix microstructural appearance. Thus, both added carbide and plasma sintering improved density, hardness, flexural strength and microstructural appearance of the composites

Análise do estado da arte dos aspectos diagnóticos, periciais e jurisprudenciais das LER/DORT no contexto previdenciário das doenças do trabalho no Brasil

Objetivo: analisar o estado da arte dos aspectos diagnósticos, periciais e jurisprudenciais das LER/DORT (Lesões por Esforços Repetitivos / Distúrbios Osteomusculares Relacionados ao Trabalho) no Brasil. Materiais e Método: trata-se de pesquisa descritiva, de natureza qualitativa, com formato documental, utilizando-se a técnica de análise de conteúdo. A avaliação evolutiva da legislação previdenciária relacionada as LER/DORT foi realizada através da pesquisa no banco de dados disponibilizado pelo Governo Federal e mediante a consulta ao DATAPREV/Sislex. A avaliação dos aspectos diagnósticos foi instrumentalizada através, principalmente, de artigos científicos publicados entre 2003 e 2008, nas línguas portuguesa, inglesa, espanhola e francesa, relacionados com os métodos de diagnósticos complementares das LER-DORT (ressonância magnética, tomografia computadorizada, ultrassonografia e eletroneuromiografia). As jurisprudências foram obtidas através da busca dos julgados sobre o tema, entre 2003 e 2008, pertencentes ao Supremo Tribunal Federal, Superior Tribunal de Justiça, Tribunais Regionais Federais, Tribunal Superior do Trabalho e Tribunais Regionais do Trabalho. Resultados: foram identificados 48 artigos abordando os aspectos diagnósticos das LER-DORT, observando-se que os exames por ressonância magnética, ultrassonografia e eletromiografia demonstraram ser mais efetivos, dentro das suas especificidades, para a complementação do exame clínico de patologias relacionadas às LER-DORT. A análise das 123 jurisprudências selecionadas demonstrou, de forma geral, que as LER-DORT equiparam-se ao acidente de trabalho, devendo apresentar nexo de causalidade (atestado através de laudo médico-pericial) e, ainda, ensejam a ação por danos morais, a qual, devido à EC nº 45 passou a ser competência da Justiça do Trabalho. O Estado da arte dos aspectos periciais encontra-se representado pela vigência da Instrução Normativa n. 98/2003, a qual traz como aspecto fundamental a determinação de novos parâmetros a serem considerados na definição de um quadro de LER-DORT, dispondo, ainda, sobre a conduta ética que deve ser adotada pelo médico perito, bem como chama a atenção para a necessidade dessas doenças do trabalho serem comunicadas às autoridadades competentes, através da emissão da Comunicação de Acidente de Trabalho (CAT). Conclusão: as LER-DORT representam, hoje, um problema de importante impacto, não apenas previdenciário, mas também econômico em diversos países, nos quais o Brasil encontra-se inserido. Estudos sobre o estado da arte relacionados às LER-DORT são fundamentais para auxiliar na construção de um modelo crítico e consciente que colabore com a garantia de sustentabilidade do sistema previdenciário no Brasil

Representações sociais sobre o acidente de trabalho em saúde

The aim of the present study was to identify the representational elements of workrelated accidents in the health field, as well as investigate their most frequent occurrences at a university hospital, seeking to understand the cognitive, affective and social elements subjacent to the work process involved in health. The analysis focused on 470 middle and senior support staff of this hospital, based on the theoretical-methodological support of the Social Representations Theory. A combination of the following instruments was used for data collection: a free wordassociation test, a questionnaire, an interview and a field journal. Evoc 2000 software was used to identify representational structure. Chi-square and Mann-Whitney tests, at a significance level of 5%, were performed to verify the association between the independent variables and the occurrence of work accidents. In addition, thematic content analysis and lexicographic analysis by ALCESTE software program were used to understand textual content. It was observed that social representations of work-related accidents in the health area are centered in the contamination category, while the categories of prevention and professional unpreparedness are found peripherally. There was a significant association between the existence of multiple employment, the use of personal protective equipment (PPI) during work, job satisfaction and the occurrence of work accidents. The conclusions indicate that perforating-cutting occupational accidents predominated in the hospital and that the representations of the subjects intertwined, with a traditional discourse of work accidents strongly present in Occupational Health. It is therefore suggested that certain subjective aspects related to culture, in terms of controlling work accidents, such as: management, process, organization and the increasing precariousness

O trabalho doméstico de adolescentes: naturalização da exclusão e submissão

This work demonstrates important aspects of domestic work performed by adolescents between 16 and 18 years in residential spaces. This is to highlight the process of naturalization of invisibility, their source of insecurity and social exclusion, in view of the strong personal relationship of domination. Pointing out the relations of pseudo-affection that can obscure the exploitation of domestic labor. Highlight a preliminary discussion on the composition of social relations embedded in the context of domestic work, with emphasis on reflection on the condition of subordination of young domestic workers as a result of a process of socialization consists of relations of domination - gender and social class, resulting in formation of social identity-forming negative stigma. This paper results from a survey of the work of young maids, held in the city of Aracaju, whose main objective was to understand how they operated the differences and inequalities in the relations of domestic based, including information on adolescents' own. Fieldwork was conducted from August 2009 to January 2010 and data collection techniques were used oral history / life history, questionnaires and use of semi-structured interviews, as well as secondary data from PNAD / IBGE which formed the basis of comparative national situation and local context. It emphasizes the links of domestic work involving teenagers question the lifestyles of working class who are confronted by the various "systems" for each home, which leads to the development of adaptation strategies that make possible the coexistence of a stranger the house at the other. It focuses on how the work goes into their lives in terms of socialization offered by working families to their children's, and as this class habitus is adequate for the job market in domestic employment through a socialization process that sometimes opposes and now reinforces the practices and values seized in family socialization
