Henri Lefebvre: possibilidades teórico-metodológicas para Arquitetura e urbanismo

This paper presents the theoretical-methodological possibilities of the French philosopher and sociologist Henri Lefebvre, for the discipline of architecture and urbanism in an effort to overcome the fragmentation imposed by the institutionalization of science in general. From Du rural à l'urbain (Lefebvre, 1970) compilation, it brings the author's other works from the period between 1968 and 1974, indicating the conduits for reflection and their interrelationships with methods, types of analyses and other procedures to treat the space-time urban. The methodology involves a research on the author s 'today and yesterday' in the scientific field, a research and analysis of his procedures in highlight of philosophical, social, economic and political aspects, the historical context of his references and provides significant and possible elements for the study, research and extension in the area in question

Experienciando a ausência do companheiro nas consultas de pré-natal

This research aimed to understand pregnant general meaning about consort absence in prenatal care. It s an exploratory and descriptive qualitative approach, developed at Centro de Saúde de Jardim Lola, São Gonçalo do Amarante / RN. Participated in investigation 20 pregnant enrolled in prenatal program, their aged over 18 years, guidance of mental faculties and who survive together her partner. Data were collected from March to May 2009, through semi-structured interview. The analysis was processed according to grounded theory and symbolic interactionism as theoretical and methodological references. To support discussions were used literature findings involving political aspects of women humanization in health care and gender relations within family. Following footsteps of points it were adopted derived following sub categories: ¨Realizing involvement of consort during prenatal¨, ¨Expressing feelings during prenatal¨ and ¨Manifesting attitudes during prenatal period¨. These, when they had their properties and dimensions analyzed, resulted in the main category ¨ Experiencing absence of compeer in clinical prenatal¨. The construction of this theory leads to conclusion that women understand absence of her partner, attributing this to even work at the moment prenatal care or does not like to attend health institutions. However, this does not mean that his presence is dismissed, because desire to be with him in prenatal care was mentioned by most interviewees. So, partner absent at time, leads women to experience desires, feelings, attitudes, perceptions and expectations about studied phenomenon. This reality, induce that absence of them partner in prenatal care predisposes women to strengthening of discomforts arising from pregnancy and therefore goes against wellbeing of pregnant, and ensure the possibility of marital discord. This requires professional nursing measures to get in inclusion of partner in daily pre-natal care in humanization perspective.

Segurança da informação no correio eletrônico com base na ISO/IEC 17799 :um estudo de caso em uma instituição superior com foco no treinamento

The electronic mail service is one of the most Internet services that grow in the corporate environment. This evolution is bringing several problems for the organizations, especially to information that circulates inside of the corporate net. The lack of correct orientation to the people, about the usage and the security importance of these resources, is leaving breaches and causing misusage and overuse of service, for example. In recent literature, it starts to coming out several ideas, which has helped to rganizations how to plain and how to implement the information security system to the electronic mail in computer environment. However, these ideas are still not placed in practice in many companies, public or private. This dissertation tries to demonstrate the results of a research that has like goal, identify the importance that user training has over the information security policy, through a case study inside of private superior education institute in this state. Besides, this work had by basic orientation the ISO/IEC 17799, which talk about People Security. This study was developed over a proposed model to this research, which looked for offer conditions to guide the institution studied, how to plan better a information security policy to the electronic mail. Also, this research has an exploratory and descreptive nature and your type, qualitative. Firstly, it was applied na questionary to the information technology manager, as better way to get some general data and to deepen the contact which still then, it was being kept through e-mail. Thereupon this first contact, eleven interviews were done with the same manager, beside one interview with twenty-four users, among employees e students. After that to collect and transcript the interviews, were review with the manager all informations given, to correct any mistakes and to update that informations, to then, start the data analyze. The research suggests that the institution has a pro attitude about the information security policy and the electronic mail usage. However, it was clear that answers have their perception about information security under a very inexperient way, derived of a planning lack in relation to training program capable to solve the problem

A formação pós-graduada em ensino de ciências naturais e matemática de docentes do IFRN: implicações na atuação docente

This research part of the educational context of the Federal Rio Grande do Norte, through the resumption of legal frameworks that characterize it as an institution belonging to the Federal Network of Professional Education and Technology Brazilian, with a focus on continued education policies for the servers who work there specifically teachers, especially those who have their work in the Teaching of Natural Science and Mathematics. To do this the cut in an agreement between the IFRN and UFRN PPGECNM through the professional master's degree Teaching of Natural Sciences and Mathematics. This agreement as we have research collaborators 08 master teachers who graduated in the period 2004 to 2010, so we undertook a qualitative and quantitative research aimed to conduct the study in general terms of description and analysis of the impacts caused by the formation of masters IFRN in PPGECNM UFRN, taking into account the production of the same academic (dissertation), his performance in the context of the institution and the historical, social, economic and political aspects involved, and also meet the guidelines of the project at the Observatory in 2008 - MEC / CAPES / BSD-P. We used the theoretical options methodological elements of Comprehensive Interview and multireferentiality, our data collection instrument was the main interview, we also performed the analysis of dissertations by lecturers and teachers featured, from the specific descriptors used in catalogs USP / IFUSP (1992, 1996) and UNICAMP / FE / CEDOC (1998) and by other researchers. In analyzing and understanding the speech of the interviewees were able to identify the implications of teacher education in the school context, the motivation to seek the Master; how was the construction of the object of study of the educational product and its use in teaching practice and intervention, the question of the role of master teachers in the school environment to the post master taking into account changes in professional performance and influence in the working groups, how does the use of research and investigation in the classroom after training and between training and educational quality in the context of IFRN. In reading and analysis of the dissertations were able to identify the main focus and under-explored thematic focus as well as the theoretical methodological references. At the end of the research developed a product that could be used for technical analysis studies and assessment in quantitative terms the results achieved by the master teachers IFRN through his training in PPGECNM UFRN

Instrumentalidade do serviço social na previdência social no Brasil contemporâneo

In the sociability of the capital, the challenges to the consolidation of social security as a public policy become expressive, which has implications for social security services, particularly for Social Works who works for the security and fulfillment of social rights. Therefore, in this context of denial of these rights becomes relevant the work of social worker, as a professional committed to the ethical-political project and the Matrix Theory and Methodology of Social work, which potentiate the action able to establish professional articulated strategies for the strengthening of collective struggles for equality in society. Thus, this study examines the instrumentality of social work in the contemporary world and its contribution to the realization of rights. For this, we conducted a literature review, using authors dealing with the issue, as Behring (2008), Boschetti (2003), Mota (1995), Guerra (2007) among others, as well as documentary research through laws, decrees, instructions Normative, Internal Guidelines, and especially the analysis of the Matrix itself of Social Work in welfare. We use also of paramount importance to our analysis - the field research, using techniques such as semi-structured interview and questionnaire. The research enables the identification of important aspects of the subject studied, as the understanding of professionals about the instrumentality of Social Works in its ethical-political aspects, both theoretical and methodological and technicaloperative. The demands made by the managers for the profession on the sociooccupational have extrapolated the powers and duties of the Law Regulating the Profession and the Matrix of Social Work in welfare. The subjects of this study emphasize the role of social category of the National Institute of Social Security and the Federal Council of Social Service in defense of Social Works. The knowledge of social and institutional framework is critical to building control strategies that strengthen social security and public policy, the guarantor of social rights for workers in Brazil

Relações entre pesquisa em ensino de Ciências e formação de professores: algumas representações

Este estudo foi realizado com o objetivo de investigar representações de pesquisadores da área de ensino de Física sobre a possível interferência da pesquisa da área de ensino de Ciências na maneira como se formam professores no Brasil. Para tal, foram analisadas as respostas a uma questão formulada em entrevistas a treze pesquisadores do ensino da Física, indicados por seus pares por meio de correio eletrônico encaminhado a pesquisadores do ensino de Ciências, incluindo as subáreas de Biologia, Física, Geociências e Química. A análise de discurso desenvolvida na França por Michel Pêcheux, a partir de subsídios obtidos principalmente em publicações de Eni Orlandi no Brasil, foi o apoio teórico que sustentou o estudo. As representações que os discursos selecionados permitem inferir evidenciam pequena influência. Entretanto, foram enunciados fatores de grande abrangência, incluindo desde aqueles internos à própria área, quanto fatores associados a políticas públicas. Também se observou uma diversidade de posições entre os pesquisadores entrevistados. No conjunto, os fatores abordados pelos entrevistados constituem um amplo quadro configurativo de representações que pode ser elemento de reflexão para outros pesquisadores. Acreditamos que essas representações têm potencial de contribuição para efetivas interferências na forma de realização de políticas públicas, sem a necessidade do uso de prescrições e cada vez menos com recomendações vazias.

Networked control system for the guidance of a four-wheel steering agricultural robotic platform

A current trend in the agricultural area is the development of mobile robots and autonomous vehicles for precision agriculture (PA). One of the major challenges in the design of these robots is the development of the electronic architecture for the control of the devices. In a joint project among research institutions and a private company in Brazil a multifunctional robotic platform for information acquisition in PA is being designed. This platform has as main characteristics four-wheel propulsion and independent steering, adjustable width, span of 1,80m in height, diesel engine, hydraulic system, and a CAN-based networked control system (NCS). This paper presents a NCS solution for the platform guidance by the four-wheel hydraulic steering distributed control. The control strategy, centered on the robot manipulators control theory, is based on the difference between the desired and actual position and considering the angular speed of the wheels. The results demonstrate that the NCS was simple and efficient, providing suitable steering performance for the platform guidance. Even though the simplicity of the NCS solution developed, it also overcame some verified control challenges in the robot guidance system design such as the hydraulic system delay, nonlinearities in the steering actuators, and inertia in the steering system due the friction of different terrains.
