Um estudo do perfil de formação dos técnicos de segurança do trabalho no Brasil na perspectiva de sistemas de gestão de segurança e saúde ocupacional

This work provides great contribution to the documental study of the Work Safety courses offered by CEFETs in Brazil, under the perspective of safety management and occupational health, using as a referential the specification OHSAS 18001 (BSI, 1999), as well as directions provided by OIT (ILO, 2001). The theoretical research compares technical and managing competences of the projects of Work Safety courses at CEFETs with the international legislation mentioned above. For field research, questionnaires containing open and close questions were answered by teachers and students aiming at identifying the importance of technical and managing competences for the formation of Work Safety technicians, besides trying to identify which level of minimal formal knowledge should be required to perform managing activities in the area of Work Safety Management Systems and Occupational Health (SGSSO, in Portuguese). The results of the theoretical research point out differences between the projects of the Work Safety technical courses at CEFETs under the perspective of SGSSO. The field research shows that students and teachers opinions converge about most technical and managing competences. In relation to academic formation, the research suggests divergences to the criterion stated by the norm ISO 19011(ABNT, 2002)

Gestão ambiental na educação: um estudo sobre fatores que afetam o comportamento ambiental de professores do ensino médio, na cidade de Floriano-PI

The present work sets out environmental issues in educational field. The aim of this research was to investigate the factors capable to influence the environmental behavior of the teachers in High school of the public school in Floriano, state of Piaui. For this, the methodology utilized an explanatory and descriptive search like a survey; questionnaires were applied with open and close questions establishing shifts that made up the following aspects; knowledge, behavior, responsibility, participation and trait of the teachers. The statistic techniques to analyze the data were descriptive analysis and analysis of multiple regression. The results reveal that teachers care about the real surrounding problems and believe that the school must develop ambient activities to stir the consciousness, it is important to the environmental improvement of the city. However, the results point out that are developed little activities related to theme concerned, besides the level of ambient consciousness given to the students are median. It was observed that teachers have little knowledge about theme like Agenda 21 and ISO14000. After identifying some factors of environmental knowledge, it was showed recommendations. The Agenda 21 recognizes in the educational field a mean of popular consciousness; the school should develop an education according to national policy of the environmental education

Avaliação da importância dos sistemas de gestão da qualidade nas universidades federais

This thesis aims at analyzing from the perspective of the manager the importance of the use of quality management tools and concepts in Federal Universities. It was motivated by the following research problem: do Federal University managers consider it to be relevant the quality management in their institution? Therefore, we sought to gather evidence for a satisfactory approach that addresses the complexity of the topic researched: quality, higher education and quality management systems. We chose to adopt an applied study, the exploratory-descriptive research as to the objective and the quantitative and qualitative research as to the approach to the problem. The object of study is composed by the Planning Provosts of Federal Universities listed in the University Ranking Sheet - (RUF) in 2013. We chose to restrict the sample listing only the provosts of the 20 best-placed universities in the ranking of the Federal Universities. The research instrument was composed of 26 questions, of which 6 questions were designed to identify the profile of the manager, 16 questions of perception (manifested variables) on the importance of quality management in the University, where the managers assigned values (answers) to the affirmatives (that address the main topic of this thesis) based on a Likert scale of 5 points, and 4 open and optional questions, in order to identify general management practices used. It was used for statistical analysis (data analysis) descriptive and factorial statistics. The responses collected through the questionnaire portray the managers´ perception regarding the importance of quality management in their institutions. Sixteen variables were addressed, the results of factor analysis of importance were "Important" and "Very Important", where the variable (V2) was "Important" and all others "Very important." With this information, it is possible to prioritize some areas that deserve immediate action. As it was observed that some variables are "Very important" for the vast majority of managers, others did not show the same result as example (V2, V10, V11). It is concluded that the manager´s perception of quality management in his or her institution is relevant, but the same importance is not given to quality programs implemented in other segments of the economy, and that, despite the advancements offered by SINAES, the model does not evaluate the institution in a global way. Thus, with the results, it is expected to contribute to the advancement of the subject, trying to arouse interest from the managers of Federal Universities in the subject, emphasizing the importance of quality management systems as a necessary tool to raise the institutional quality

Análise da eficiência de aquecedor solar espiral com e sem efeito estufa para piscinas

The technical and economic viability of solar heating for swimming pools is unquestionable, besides there it replaces the high costs and environmental impacts of conventional supply of energy, and it improves an optimization in the pool heating uses. This work applies the principles of the greenhouse effect: advanced thermodynamics, heat retention and equalization of temperature, to optimize the solar heating equipment, reducing the area required by collectors as much as 40% (still estimated value) for commercial collectors, with minor architectural and aesthetic impacts on the environment. It features a solar heating alternative in pools, whose main characteristics: low cost, simplicity in manufacturing and assembly and a faster heating. The system consists of two collectors spiral hoses made of polyethylene with a hundred meters each, and working on a forced flow, with only one pass of the working fluid inside the coils, and is used to pump itself treatment of pool water to obtain the desired flow. One of the collectors will be exposed to direct solar radiation, and the other will be covered by a glass slide and closed laterally, so providing the greenhouse effect. The equipment will be installed in parallel and simultaneously exposed to the sun in order to obtain comparative data on their effectiveness. Will be presented results of thermal tests for this the two cases, with and without transparent cover. Will be demonstrated, by comparison, the thermal, economic and material feasibility of these systems for heating swimming pools.

Envelhecimento ambiental em compósitos poliméricos à base de tecidos de reforços híbridos

The utilization of synthetic fibers for plastic reinforcement is more and more frequent and this growing interest requires that their mechanic behavior under the most variable conditions of structural applications be known. The use of such materials in the open and exposed to the elements is one of them. In this case, it becomes extremely necessary to study their mechanical properties (strength, stiffness) and the mechanism of fracture by which the environment aging them out. In order to do that, the material must be submitted to hot steam and ultraviolet radiation exposure cycles, according to periods of time determined by the norms. This study proposal deals with the investigation of accelerated environmental aging in two laminated polymeric composites reinforced by hybrid woven made up of synthetic fibers. The configurations of the laminated composites are defined as: one laminate reinforced with hybrid woven of glass fibers/E and Kevlar fibers/49 (LHVK) and the other laminate is reinforced with hybrid tissue of glass fibers/E and of carbon fibers AS4 (LHVC). The woven are plane and bidirectional. Both laminates are impregnated with a thermofix resin called Derakane 470-300 Epoxy Vinyl-Ester and they form a total of four layers. The laminates were industrially manufactured and were made through the process of hand-lay-up. Comparative analyses were carried out between their mechanical properties by submitting specimen to uniaxial loading tractions and three-point flexion. The specimen were tested both from their original state, that is, without being environmentally aging out, and after environmental aging. This last state was reached by using the environmental aging chamber

A interpretação semântica dos auxiliares modais poder, precisar e dever: uma abordagem da semântica cognitiva

Apresentamos, neste trabalho, com base na semântica cognitiva, uma análise do significado, em contexto, dos auxiliares modais poder, precisar e dever. Analisamos 120 textos produzidos por candidatos ao vestibular e por alunos do ensino fundamental, como resposta da questão número três da prova discursiva de Língua Portuguesa do vestibular 2005 da UFRN, que pede aos candidatos para explicitar a diferença de sentido entre três frases, observando o uso desses três verbos. Consideramos que um item lexical não é incorporado a uma representação lingüística semântica fixa, limitada e única, mas antes, é ligado a uma representação lingüística semântica flexível e aberta que provê acesso a muitas concepções e sistemas conceituais dependente de cada contexto determinado. Com base em seu significado, um item lexical evoca um grupo de domínios cognitivos, que por sua vez, apresentam um determinado conteúdo conceitual. Isto implica em afirmar que a rede de significados lexicais vai variar conforme o conhecimento de mundo de cada um (LANGACKER, 2000). A relevância deste trabalho é proporcionar uma contribuição para a descrição semântica do português

Increasing Moodle Resources Through Cloud Computing

The increase of higher education offer is a basic need of developed and emerging countries. It requires increasing and ongoing investments. The offer of higher education, by means of Distance Learning, based on the Internet, is one of the most efficient manners for the massification of this offer, as it allows ample coverage and lower costs. In this scenario, we highlight Moodle, an open and low-cost environment for Distance Learning. Its utilization may be amplified through the adoption of an emerging Information and Communication Technology (ICT), Cloud Computing, which allows the virtualization of Moodle sites, cutting costs, facilitating management and increasing its service capacity. This article diffuses a public tool, opened and free, for automatic conversion of Moodle sites, such that these may be hosted on Azure: the Cloud Computing environment of Microsoft.

Desempenho muscular e equilíbriu postural em idosas frágeis residentes na comunidade

Human aging is physiological process causes alterations in several systems of the organism. In the musculoskeletal system, a main change is the decreased muscle strength, that in the lower extremity, compromises the ability to respond quickly with enough strength to prevent falls, causing alterations in postural balance. Currently, many researchers have study the human frailty, defined as a multifactorial syndrome, with excess of vulnerability to stressors, reducing ability in maintaining or regulating homeostasis. Its characteristics are directly related to physical function. Aim: To analyze muscle performance and postural balance in frail and pre-frail elderly women, and to compare them according with the frailty phenotypes criteria proposed by Fried 2001. Method: 39 frail elderly women living in the community, aged 65 years and older, were assessed muscle performance of lower extremity using isokinetic dynamometer and postural balance using Berg s balance scale and computerized baropodometry. Results: There was significant difference in plantar flexor, knee flexor and knee extensor strength, in anteroposterior (AP) oscillation with eyes open and on Berg s scores between groups. A weak correlation was observed between strength and balance. Conclusion: The results suggest that the frail elderly present worse muscle performance in lower extremity and worse postural balance compared to the pre-frail elderly. There were correlations between muscle performance and balance impairments in these elderly, but several variables are also involved in maintaining postural balance

Além das xícaras: a construção do Café São Luiz como lugar de memória em Natal (1950-1980)

This research stands in discussions involving the relationship between memory, history and space. We will work with the Café São Luiz in the neighborhood of Cidade Alta in Natal, an place which remains open and founded in 1953. The place was opened in the district of greater movement of the 1950s, a zone of concentration of commerce and leisure. In consequence an impulse of memory, the Café São Luiz was represented by different statements, which they built a space that serves to support memory and identity of a group. The speeches elaborate the Café São Luiz as a monument, a place of memory according to Pierre Nora. Among these discourses of construction of the Café São Luiz stands out the 1982 book titled Na Calçada do Café São Luiz by José Luiz Silva. This research aims to discuss the construction of the Café São Luiz as a place of memory, questioning their representations, traversing the authorship of speeches over the place

Comércio internacional e meio ambiente: estímulo à produção sustentável ou mero protecionismo comercial a posição do Brasil em dois casos de litígio

The World Trade Organization (WTO) was established in 1994 as a result of the Uruguay Round, and has as its principal aim advocate for the maintenance of free trade between nations. The preamble of its Constitutive Agreement specifically cites as an institution the goal of achieving sustainable development and the pursuit of protecting and preserving the environment, bringing into the sphere of world trade the idea that concern for the environmental cause is not restricted only the group of environmentalists, but rather has entered the economic landscape in a way not only ideological, but also pragmatic. The General Agreement on Tariffs and Trade (GATT) 1947, part of the GATT 1994, contains a device that allows the adoption of trade restrictive measures, provided that such measures aimed at protecting the environment - Article XX. The Settlement Body (DSB) is part of the WTO and acts in dissolving disputes between the countries motivated by trade. It examines two cases where countries have imposed restrictive trade measures with environmental justification. The first case was closed in 1996, with award of damages given to Brazil, on the breakdown of U.S. environmental legislation imposed on imported gasoline from Brazil - and the second, begun in 2005 and closed in 2007, coming out victorious again Brazil is on the import ban on retreaded tires to Brazil. The objective is to answer the question: how the environment is treated in the midst of trade discussions - which is aimed at its protection or its use with economic objectives in disguise? For the preparation of this work, extensive documentary research was undertaken with the virtual site of the WTO to review the entire production of legal cases and subsequent analysis of the key issue for the work, and literature of authors who have studied the tense relationship between trade international environment. The first case, it could be seen that the political movement performed by the U.S. with the aim of achieving acceptable standards of air quality was an institutional effort to ensure the quality of air, and thus would be inappropriate to say that the regulation of gasoline was merely a disguised trade barrier.However, a careful analysis of the implementation and operation of gasoline regulation may reveal intentions disguised trade and U.S. environmental argument did not hold. The weight of this environment was relegated, since there were clearly outside interests to the environmental cause. The second case, it was realized that, despite clear attempts by the EC to promote ecological dumping, send when brought to Brazil, supposedly a country with weaker environmental structure on surveillance, a residue that, pursuant to internal policies, as could not be sent to their own landfills, the Brazilian discourse remained focused on the environmental cause, and this sort there was the existence of disguised trade barriers, but of importance, at least a priori, the discussion of foreign forces on the environment environment because there is no way to legally justify the reversal of the total understanding of the first judging body, the sight of all the arguments presented by Brazil and the nonsubmission of new facts upon appeal. Still, quite heartening to reflect on the role of trade liberalization on the environment in general, because, while they do not reach a definitive conclusion will reveal positions in both directions, both for and against, the that only adds to the discussions and makes this a very fertile topic for future research

Impactos sócio-econômicos e ambientais da introdução da Tilápia do Nilo, Oreochromis niloticus, em açudes públicos do semi-árido nordestino, Brasi

The stocking of exotic fish, especially the tilapia, has become a common practice in the public reservoirs of the Brazilian semi-arid region. The stocking of tilapias has had as its main aim the improvement of the fisheries in the reservoirs and consequently the improvement of the socio-economic conditions of the families that have fishing as the main source of income. However, the environmental risks associated with this practice are high and can lead to a loss in aquatic biodiversity and to changes in the quality of the water. The object of this work was to quantify the socio-economic and environmental effects of the introduction of the Nile tilapia in the public reservoirs of the semi-arid northeastern Brazil. The analysis of the fish yield of 100 public reservoirs from 1970 to 2000 demonstrated that the introduction of the Nile tilapia apparently contributed to an increase in the total fish yield from the late 1970 s until the mid-1980 s. Nevertheless, from that time onwards the fish yield in these reservoirs has fallen into decline to levels inferior to those observed prior to the introduction of the tilápia. The analysis of the fishing activity statistics of the Gargalheiras reservoir located in the city of Acari, Rio Grande do Norte, demonstrated that the introduction of the Nile tilapia in the reservoir has not significantly increased the fish yield, the gross overall income, the gross per capita income nor the number of fishermen actively fishing in the reservoir. On the other hand, the analysis of the fishing activity statistics of the Gargalheiras reservoir has revealed a significant reduction in the captures of other commercially important fish species after the introduction of the tilapia. This result suggests that the Nile tilapia could have negatively affected other species of fish in the reservoir, contributing to the decline in their stocks. In order to assess the perception of the fishermen concerning the effects of the Nile tilapia over other species of fish and the quality of the water, questionnaires containing open and multiple choice questions were applied with 30 fishermen from the colony of the Gargalheiras reservoir. The great majority of the local fishermen stated that the tilapia is currently the most important species of fish to those who depend on fishing as a source of income and that they have not caused damage to other species of fish nor to the quality of the water in the reservoir. However, the results of the present work indicate that the alleged socio-economic benefits, employed to justify the introduction of the Nile tilapia in the reservoirs, are overestimated while the environmental impacts of the introduction of this exotic species are underestimated

A dinâmica territorial da Assembléia de Deus do seridó do Rio Grande do Norte

In the norte-rio-grandense backwoods is possible to join to the power forms both political and economical ones, religious groups keeping under your control areas, people and flow of them, as well as settling new places of acts. That control refers to a field of power delimited by space, in other words, it refers to a territory marked and planned to reproductive intentions on the space. In relation to the religious pluralism, the Assembly of God church, in your territorial dynamics, has been standing out by the strategies of delimitation and space increase which by a constant territorial division process (1943-2010) managed to widen material and symbolic scale of its power for all cities of the Rio Grande do Norte backwoods. The Assembly of God church as the greatest Pentecostal denomination of Brazil was formed in the Rio Grande do Norte Seridó, following a ecclesiastical and governmental model divided into three ecclesiastical fields hosted in those following cities: Caicó, Currais Novos and Parelhas. Those headquarters interlink a limited number of churches through normative codes, which they express a functional dimension (bureaucratic) and in another symbolic one (charismatic) in an only field of territorial control. In this manner, the maintenance of the territorial power in the Assembly of God church is done by a charismatic-bureaucratic administration, expressed in the interdependent of material and abstract mechanisms. The believers permanent contact toward those mechanisms of institutional control revealed territorial identities which causes a feeling of property of the believer as much to the Pentecostal belief system as to community of the Assembly of God church. Considering new possibilities of articulation of the Rio Grande do Norte backwoods towards others territories more multiple, culturally, noticed cultural adjustments and revaluation at themselves. In relation to the territory of the Assembly of God church this one has exposed itself defensive faced with that cultural hybridization tendency, resisting a closer dialogue to new symbolic elements, mainly those came from the multifaceted neo-pentecostal movement. Unlike more open and flexible churches towards others significant systems, The Assembly of God church tries to reinforce the boundaries of its territory considering by the orthodoxy of its routine and customs

Adesivos à base de cianoacrilato para síntese de tecido mole

FUNDAMENTOS - Adesivos teciduais têm sido muito usados para síntese de ferida, em função de ser um método indolor, rápido e de fácil execução. OBJETIVOS -Analisar e comparar compatibilidade dos adesivos, etil- cianoacrilato (Super Bonder) e butilcianoacrilato (Histoacryl), e a reparação de incisões em dorso de ratos entre o fio de sutura e os respectivos adesivos. MÉTODOS - Foram usados 15 ratos. Realizaram-se duas lojas cirúrgicas no dorso. em cada uma, foi implantado um tubo de polietileno (10mm x 1mm), os quais foram preenchidos com os adesivos Super Bonder (lado direito) e Histoacryl (lado esquerdo). As incisões, do lado esquerdo, foram coaptadas com Super Bonder, e as do lado direito, com Histoacryl. Uma incisão mediana, entre as duas incisões,foi realizada e suturada com fio de seda. Os animais foram mortos, depois de 7(sete), 35(trinta) e 120 (cento e vinte dia) dias. RESULTADOS: Os adesivos usados, no presente estudo, não promoveram reação inflamatória, quando usados para síntese das incisões. Porém, estes adesivos, quando implantados no subcutâneo, promoveram reação inflamatória até 120 (cento e vinte dia) dias, no entanto, a reação é mais intensa com Histoacryl. CONCLUSÕES: Super Bonder e Histoacryl permitem o processo cicatricial dos tecidos incisados; facilitam a sutura das incisões. Desta forma, estes podem ser utilizados para sínteses de feridas, lacerações ou incisões cutâneas.
