Serviço Social e terceiro setor: considerações sobre as atuais relações e condições de trabalho para o Assistente Social em Natal

The present study analyses the actual relations and work conditions found in the third sector in Natal city, in the context of productive restoration and increasingly retraction from the State in providing Social Service before the new approach that has been destined to the social issue. The study talks about the work of the social worker when fighting the different expressions the social issue has, such as social service provision as a way of teamwork associated to work relations and conditions, to accessible resources and quality control management. These are elements that affect and interfere in the accomplishment and in the work of the social worker itself. The State s improvement, according to neoliberal-political precepts and increasingly retraction from the public investment in the areas of social concern (health, social welfare, assistance) and in the wage and employment policy, besides expanding the partnership with the public and private areas, in search for social services with quality, it has diversified the structures of the professional work with the growth of the so called third sector institutions. However, the absorption of the social workers by the third sector groups in general, has as major features the impoverishment of work relations, the maintenance of an unequal salary model, pointing out the deadline contracts and/or single tasks that generate work instability. The research debates, with a critical view and full perspective, over the conception of the third sector, interpreted as an action that expresses functions and values, treated as a real phenomenon generated from the restoration of the capital based on neoliberal principles. This study aims for responding what the established work relations are and under what work conditions the social worker has been fitting in the third sector and how such a reality echoes in the current work conditions for a social work in the city of Natal, before this new model of state intervention that transfers part of the social service provision to distinctive divisions of society, among them the so called third sector. The research results have shown that like the other workers the social worker passes through the same crises, dilemmas, advances and challenges that occur in the world of employment and which are expressed in the drop of salary average in the growth of contemporary contracts, unemployment, and in the ever more selective requirements to one be included in the social spaces, where the professional work is done, having as a result a greater impoverishment of work relations and conditions as well as more vulnerability as a salaried occupation

As relações de gênero no trabalho: uma análise da inserção das mulheres e homens na rede de fast food

The purpose of this study was investigate the sexual division of the work in a chain of fast food, in Natal, RN. These aspects were analyzed with the ways of organization of the work, being made a case study. The main objective of this survey was to analyze the influence of gender relations in the insertion of men and women in the job market and to analyze the question of feminine submission in the professional world. These questions were analyzed considering the current period of the worldwide capitalism, from the characteristics of productive process and the growth of the service sectors. The research was made with a group of workers on the production sectors; attendance, management and human resources at restfood store, where six clerks were interviewed. Through our research, it is possible to perceive the permanence of the sexual division at the job in the interior of the productive processes at Restfood, that puts the woman in a subordinate position in relation to the man. This result can be confirmed if we considerate that the women, on this chain of food, occupy in first place the function of waitress and on this, trere s no functional progression, while her workmates (the men) for occupying other functions can progress inside the company. It was also evidenced that in a context of globalization of the capital, deregulation and disrespect of labor laws, the capital acts without any respect to workers. That was what we observed at the interviewer speech; the scarcity of the conditions of work and the constant disrespect of the labor laws. This way, we could evidence that the scarcity of work conditions hit men and women, but it has a crueler face with the women, and this one reproduces itself, day by day in the process of social reproduction, through family life, insertion in the world of the work, information and received social education. So, the capital explores all of them, but the gender relations create to the capital, the possibility of a different degree of exploration, becoming this way, the women main victims herself

Violência nas escolas: Um novo olhar ante as relações sociais

The most varied ways of manifestation of the violence phenomenon in the contemporary society are each time more found in the media spaces and among society discussions. It makes think about procedures to be taken before the growth and new outbreaks of such phenomenon. The violences manifestations in schools reveal themselves as a reflection of what happens in the scope of social violence. Its dynamics originates in society and reflects itself in scholl, that is, the violences in schools combine internal and external elements to school enviroment of many fields and spheres of which the individuals participate. To reflect about the violences in the schools requires, over all, to make a bridge with the categories: youth and violence. Violences in schools: A new look to the social relations, is a Ms. Sc. Dissertation that has as main objective: to analyze the main existing forms of violence in the school space. For its achievement, it was made a bibliographical survey, questionnaires application (annexed) and observation. Thus, this research articulated the two approaches: qualitative and quantitative. The questionnaires application happened in a state school of the Natal city and amongst yhe criteria for this choice there was the fact of the school had more than 500 pupils, to be located on a strategical place of the city, providing a subjects heterogeneity to be researched, deyond the limitations of available resources financial and material and the available time for the research accomplishment. The scool congregates objective conditions, specifically in what concerns the criteria previously defined: age range, socioenomical level and number of pupils. Amongst the main results obtained, it can be detached that the violence is a phenomenon seen, for the great majority of the research subjects, as a phenomenon connected to the most visible violence forms: the agressions. And a question always present in the public education institutions: infrastructures precariousness, high scool evasion índex and vulnerability among the pupils that makes possible to the pupil to see school as an home extension. Such dissertation concludes that the phenomenon of the violence in scools demands and requires of the most varied subjects involved in the processes na understanding of its determinants so that thus, one can intervene in such phenomenon that does not restrains itself to the physical acts of aggression, but that it is, over all, on a non respecting the different

Desempenho escolar de crianças com Distúrbio Específico de Linguagem: relações com habilidades metafonológicas e memória de curto prazo

OBJETIVO: Descrever o desempenho de crianças com Distúrbio Específico de Linguagem (DEL) em provas de leitura, escrita, aritmética, consciência fonológica e memória seqüencial auditiva, assim como, verificar se há associação positiva entre as provas que avaliam a aprendizagem escolar e as que avaliam o processamento da informação. MÉTODOS: Vinte sujeitos com diagnóstico de DEL, com idades entre 7 e 12 anos, foram submetidos ao Teste de Desempenho Escolar (TDE) e a duas provas, que avaliam o processamento da informação (Perfil de Habilidades Fonológicas e Subteste de Memória Seqüencial Auditiva do Teste de Illinois de Habilidades Psicolingüísticas - ITPA). RESULTADOS: A maioria apresentou alteração em todas as provas realizadas. As associações entre o desempenho do grupo nas diferentes provas demonstram que a habilidade metafonológica apresentou associação estatisticamente significante com as habilidades de leitura (p=0,02) e escrita (p=0,02). Por sua vez, a habilidade de memória seqüencial auditiva apresentou associação estatisticamente significante apenas com a habilidade de aritmética (p=0,0003). CONCLUSÃO: O desempenho escolar, assim como as habilidades de consciência fonológica e memória de curto prazo mostraram-se defasados na maioria dos sujeitos avaliados, havendo associação positiva entre: a prova de memória de curto prazo e a prova de aritmética; a prova de consciência fonológica e as provas de leitura e escrita. Neste contexto, reforça-se aqui a utilização de programas de intervenção baseados em Modelos Psicolingüísticos, que sugerem o uso de estratégias individuais para o desenvolvimento das habilidades metafonológicas.

Urbanização turística em ponta negra: relações de força e processos sociais no período de 1979-2009

This master thesis aimed to investigate how the power relations operating in the tourism social processes, have shaped the urbanization of Ponta Negra district, Natal, Rio Grande do Norte - RN. The study assumes that the production of space is the result of global phenomena individualized by local forces a process of glocalization. The method used was the case study. It used primary and secondary data and information were treated using the technique of content analysis. The urbanization of Ponta Negra is inserted in the context of global process triggered in the 1970s. The Park of Dunas and Costeira Highway (PD/VC) urbanization project marks the beginning of the Tourisms since 1979. The period in focus was 1979 to 2009. The tourism was dived into four major sections time: tourism in Natal before the Coastal Highway (1939-1979); Project Parque das Dunas / Coastal Highway to the first boom in domestic tourism (1979 - 1990); the internationalization of tourism (1991-2000) and, of first "boom" to "decline" of international tourism (2001-2009). Based on the historical evolution of the tourism were elected three different social processes, able to demonstrate how relations of social forces brought in space act on them and help shape the process of urbanization of the neighborhood in question: The removal of beach hut , the soccer field Botafogo Football Club and the skyscrapers . Finally, it should summarize the research identified interests and conflicts among the actors that form the thrust of spatial transformations: cultural conflicts resulting from the imposition of social practices that differ from the taste of native; clashes between different groups that reflect the duality between use value and exchange value; and interests in land values. In addition, demonstrated that the social relations that involve the production of the area are stimulated by deep-seated societal processes historically and camouflaged by market relations and a modern facade that the city has acquired in recent times; revealed that the actors are linked in networks to increase their influence and that this influence varies mainly according to economic and political power that they or their associates hold

Protozoários de vida livre em dois trechos da bacia hidrográfica do rio pirangi (RN): relações com a educação em ciências e preservação

The vast hidric wealth of Brazil gets its watersheds more susceptible to impacts that compromise the water quality, affecting the ecosystem stability of aquatic environments. The decrease in the quality of water resources also results in a decrease of its multiple uses, especially in tourist areas of the coast, where the continuous flow of people to these sites increases even further the probability of inappropriate behavior of both tourists and local residents. Studies regarding the microbiological communities are still scarce, especially on the free-living protozoa that play unique roles in the food chain of aquatic ecosystems. Due to the large role played by this group of microorganisms in aquatic environments, the present study aimed at identifying the genus and species of free-living protozoa present in two sections of the Pium River, east coast of Rio Grande do Norte, making an association between the its occurrence and trophic conditions of the environment in which they are, also checking the bioindicator capacity of these organisms in water quality. It also aimed to conduct a survey with students to identify the main difficulties regarding the knowledge of free-living protozoa and hydric transmission diseases in two public schools near the river studied in the Pium district, county of Parnamirim. The survey was analyzed by means of questionnaires at both schools. Students identified several activities developed Pium river, highlighting its multifunctionality and importance to the region. A total of 76 taxa of free-living protozoa was recorded, of these, 33 were ciliates, 19 flagellates and 24 sarcodia. The spatial and temporal patterns of these organisms to both points studied revealed the bioindicator potentiality of some effective species identified. However, knowledge about the free-living protozoa proved quite lagged, presenting misconceptions that show them as pathogenic organisms exclusively, totally disregarding their ecological role. In order to remedy the flaws existing in students in relation to the functional role of protozoa, workshops were planned on these microorganisms while also addressing issues related to hydric transmission diseases through lectures, recreational activities and interactive presentations. These practical activities of Science Education had the goal of bringing students the context of local water resources, aiming to promote a greater clarification regarding of the functional role of free-living protozoa in aquatic environments

Ambiente institucional e desempenho diferenciado na agropecuária norte-rio-grandense: quais as relações?

This thesis aims to identify how civil servants perceive changes made inthe carrying out of their work after their taking part in the Course forTechnicians in Public Management of the Government of Rio Grande do NorteState. As for the methodological procedures, an exploratory-descriptivequantitative research has been carried out through structured questionnaires appliedto 118 civil servants from the first groups of the Course for Technicians, thusshowing a margin of error of 4.18% to 95% of confidence, according to theprocedures of finite sampling. The table processing and analysis rested uponthe Statistical Package for the Social Sciences SPSS and was carried outthrough univariate, bivariate and multivariate techniques with emphasis on thetechnique called Factor Analysis. It was possible to identify that the level ofsatisfaction of the students was high and there was a clear perception by themthat the course assisted to changes in their work. Through Factor Analysis itwas verified that the factors that may be related to changes in the work of thecivil servants are "Contribution to Society", "Efficiency andEfficacy in the Work Environment", "Applicability of Contents"and "Capacitating for Leadership". The conclusion of the studyindicates that the factors obtained are directly related to the basis of thenew public management by means of guidance toward efficiency and efficacy in aperspective of leadership, the contents of the course being thus made into newattitudes toward work which end up yielding better results for society

Geologia, Geocronologia, Geoquímica e Petrogênese das Rochas Ígneas Cretácicas da Província Magmática do Cabo e suas Relações com as Unidades Sedimentares da Bacia de Pernambuco (NE do Brasil)

The area studied forms a thin NNE-directed belt situated south of Recife town (Pernambuco state), northeastern Brazil. Geologically, it comprises the Pernambuco Basin (PB), which is limited by the Pernambuco Lineament to the north, the Maragogi high to the south and the Pernambuco Alagoas massif to the west, all of them with Precambrian age. This thesis reports the results obtained for the Cabo Magmatic Province (CMP), aiming the characterization of the geology, stratigraphy, geochronology, geochemistry and petrogenesis of the Cretaceous igneous rocks presented in the PB. The PB is composed of the Cabo Formation (rift phase) at the base (polymictic conglomerates, sandstones, shales), an intermediate unit, the Estiva Formation (marbles and argillites), and, at the top, the Algodoais Formation (monomictic conglomerates, sandstones, shales). The CMP is represented by trachytes, rhyolites, pyroclastics (ignimbrites), basalts / trachy-andesites, monzonites and alkali-feldspar granite, which occur as dykes, flows, sills, laccoliths and plugs. Field observations and well descriptions show that the majority of the magmatic rocks have intrusive contacts with the Cabo Formation, although some occurrences are also suggestive of synchronism between volcanism and siliciclastic sedimentation. 40Ar/39Ar and zircon fission tracks for the magmatic rocks indicate an average age of 102 r 1 Ma for the CMP. This age represents an expressive event in the province and is detected in all igneous dated materials. It is considered as a minimum age (Albian) for the magmatic episode and the peak of the rift phase in the PB. The 40Ar/39Ar dates are about 10-14 Ma younger than published palynologic ages for this basin. Geochemically, the CMP may be divided in two major groups; i) a transitional to alkaline suite, constituted by basalts to trachy-andesites (types with fine-grained textures and phenocrysts of sanidine and plagioclase), trachytes (porphyrytic texture, with phenocrysts of sanidine and plagioclase) and monzonites; ii) a alkaline suite, highly fractionated, acidic volcano-plutonic association, formed by four subtypes (pyroclastic flows ignimbrites, fine-to medium-grained rhyolites, a high level granite, and later rhyolites). These four types are distinguished essentially by field aspects and petrographic and textural features. Compatible versus incompatible trace element concentrations and geochemical modeling based on both major and trace elements suggest the evolution through low pressure fractional crystallization for trachytes and other acidic rocks, whereas basalts / trachy-andesites and monzonites evolved by partial melting from a mantle source. Sr and Nd isotopes reveal two distinct sources for the rocks of the CMP. Concerning the acidic ones, the high initial Sr ratios (ISr = 0.7064-1.2295) and the negative HNd (-0.43 to -3.67) indicate a crustal source with mesoproterozoic model ages (TDM from 0.92 to 1.04 Ga). On the other hand, the basic to intermediate rocks have low ISr (0.7031-0.7042) and positive HNd (+1.28 to +1.98), which requires the depleted mantle as the most probable source; their model ages are in the range 0.61-0.66 Ga. However, the light rare earth enrichment of these rocks and partial melting modeling point to an incompatible-enriched lherzolitic mantle with very low quantity of garnet (1-3%). This apparent difference between geochemical and Nd isotopes may be resolved by assuming that the metasomatizing agent did not obliterate the original isotopic characteristics of the magmas. A 2 to 5% partial melting of this mantle at approximately 14 kbar and 1269oC account very well the basalts and trachy-andesites studied. By using these pressure and temperatures estimates for the generation of the basaltic to trachy-andesitic magma, it is determined a lithospheric stretching (E) of 2.5. This E value is an appropriated estimate for the sub-crustal stretching (astenospheric or the base of the lithosphere?) region under the Pernambuco Basin, the crustal stretching probably being lower. The integration of all data obtained in this thesis permits to interpret the magmatic evolution of the PB as follows; 1st) the partial melting of a garnet-bearing lherzolite generates incompatible-enriched basaltic, trachy-andesitic and monzonitic magmas; 2nd) the underplating of these basaltic magmas at the base of the continental crust triggers the partial melting of this crust, and thus originating the acidic magmas; 3rd) concomitantly with the previous stage, trachytic magmas were produced by fractionation from a monzonitic to trachy-andesitic liquid; 4th) the emplacement of the several magmas in superficial (e.g. flows) or sub-superficial (e.g. dykes, sills, domes, laccoliths) depths was almost synchronically, at about 102 r 1 Ma, and usually crosscutting the sedimentary rocks of the Cabo Formation. The presence of garnet in the lherzolitic mantle does not agree with pressures of about 14 kbar for the generation of the basaltic magma, as calculated based on chemical parameters. This can be resolved by admitting the astenospheric uplifting under the rift, which would place deep and hot material (mantle plume?) at sub-crustal depths. The generation of the magmas and their subsequent emplacement would be coupled with the crustal rifting of the PB, the border (NNE-SSW directed) and transfer (NW-SE directed) faults serving as conduits for the magma emplacement. Based on the E parameter and the integration of 40Ar/39Ar and palynologic data it is interpreted a maximum duration of 10-14 Ma for the rift phase (Cabo Formation clastic sedimentation and basic to acidic magmatism) of the PB

O sensemaking e o Comitê Regional das Associações e Cooperativas do Artesanato Seridoense :buscando compreender um complexo de relações

The generation of direction, sensemaking, is the process where the actors start to perceive the events around them establishing and creating meanings in their actions that they play daily. At the moment where they happen the interactions in a net business-oriented between the actors are that sensemaking is generated. A business-oriented example of a relationship net is the work developed for the Committee of Associations and Regional Cooperatives of Handcraft of Seridó - CRACAS. This organization, with headquarters in the city of Caicó - Rio Grande of North exists with the objective to manage the net of craftsmen of the region of the norteriograndense Seridó. The present inquiry had as objective generality to understand the generation of sensible of the activities carried through for the organizational, inserted actors in the CRACAS in Caicó/RN, directed toward the use of the resources in its daily business-oriented. The specific objectives had been) To identify the resources used for the organizational actors of the CRACAS; b) To apprehend the way for which the craftsmen play activities directed toward the control and use of the available resources in its environment business-oriented; c) To identify the role played for the organizational actors (craftsmen) in its business-oriented daily activities; d) To understand as the organizational actors of the CRACAS they generate sensible of its business-oriented activities and finally e) To verify the principles that guide the interactions of the craftsmen. Of this process of empirical inquiry, the methodology used in the inquiry consisted of a Study of Case in the CRACAS and the seven Associations of the Embroidering it. It was concluded that sensemaking happens during the accomplishment of the activity as during the confection of the products. In accordance with craftsman the financial resources do not come from the CRACAS. One evidenced that the seven cities of the business-oriented embroidering interact as a net of the handcraft and that it exists a lack of resources and infrastructure in the associations

Estudo geoquímico e geocronológico Rb-Sr e Sm-Nd em zonas de cisalhamento mineralizadas em ouro e suas relações com as rochas encaixantes e geocronológico Sm-Nd em mineralizações de scheelita na faixa Seridó

Great part of the gold mineralizations are associated with shearing zones through which circulate a great volume of fluids, that interact with the host rocks, originating leaching or precipitation of chemical elements, including gold. The studied mineralizations are inserted in the Seridó Belt. The tungsten mineralization in Brejuí Mine is hosted in calcsilicate rocks from Jucurutu Formation. The São Francisco auriferous mineralization has as host rocks mica-schists from Seridó Formation, while the Ponta da Serra and Fazenda Simpático mineralizations are hosted in orthogneisses of this fold belt basement. The research conducted on these mineralizations had the purpose of integrate the data of chemical elements behavior during the shearing/mineralizing event, and its influence on the isotopic systems Rb-Sr and Sm-Nd. The studies of chemical mobility in the auriferous mineralizations showed that elements that during the shearing displayed in general an immobile behavior were Al, Ti and Zr. Among the elements that were mobilized during the event, K and Rb showed mass gain in ali belts of transformed rocks, while the elements Ca, Na and Sr normally lost mass. Petrographic studies showed that the minerais biotite and plagioclase, in all investigated mineralizations, played an important role in the chemical reactions occurred in the transformed rocks to the generation of muscovite, cordierite and sillimanite, justifying the input of K to the formation of muscovite, and the release of Na and Ca from plagioclase to the fluid phase. In the São Francisco auriferous mineralization, the results of the Rb-Sr isotopic analysis yielded ages of 645 ± 19 Ma and 596 ± 17 Ma, with both samples, from original and transformed rocks. Two ages, 569 ± 20 Ma. and 554 ± 19 Ma., were obtained with samples frem the transformed rocks domain. These ages suggest that there were two metamorphic pulses during the emplacement of the mineralized shearing zone. The Sm-Nd data yielded TDM ages of 1,31 Ga and 1,26 Ga with 3Nd (0,6 Ga) of -0,26 e -0,40 for the original and final transformed rocks, respectively. In case of the orthogneisses of Caicó Complex, e.g. the Ponta da Serra and Fazenda Simpático mineralizations, the Rb-Sr data did not yield ages with geological significance. In the Ponta da Serra mineralization, the Sm-Nd isotopic data yielded T DM ages of 2,56 Ga and 2,63 Ga to the original rocks and of 2,71 Ga to the mineralized sheared rock, and values of 3Nd (2,0 Ga) between -3,70 e -5,42 to the original and sheared rock, respectively. In the Fazenda Simpático, Sm-Nd data yielded TDM between 2,65 and 2,69 Ga with values of 3Nd (2,0 Ga) between -5,25 e -5,52. Considering the Sm-Nd data, the TDM ages may be admitted as the age of the parental magma extraction, producer of the protoliths of the orthogneisses from Ponta da Serra and Fazenda Simpático mineralizations. The chemical mobility studies showed that in the basement hosted mineralizations, Rb achieved mass while Sr lost mass, as Sm as well as Nd were strongly mobilized. The Sm/Nd ratio remained constant, however, confirming the isochemical character of those elements. In the basement mineralizations, Rb-Sr ages are destituted of geological significance, because of the partial opening of the isotopic system during the tectono-metamorphic transformations. In the tungsten mineralization, the diagram Sm-Nd constructed with the whole-rock data of calcsilicatic and the high-temperature paragenesis (garnet, diopside and iron-pargasitic hornblende) indicated an 631 ± 24 Ma age, while with the whole-rock data and low-temperature paragenesis (vesuvianite, epidote and calcite), a 537 ± 107 Ma age was obtained. These ages, associated with the petrographic observations, suggest that there was a time gap among the hydrothernal events responsible by the formation of the high and low temperature paragenesis in the calcsilicatic rocks mineralized in scheelite

As relações entre tectonismo e seqüências deposiconais no rifte potiguar - porção SW do Graben de Umbuzeiro, bacia potiguar emersa

Through an integrated approach, using litho, chrono and biostratigraphic data, the relative importance of climate variations and tectonics were recognized in rift sediments of the onshore Potiguar Basin, Northeast Brazil. Concepts of sequence stratigraphy were applied as a template to integrate sedimentological and geochemical data (oxygen isotopes), as well as quantitative palynologic methods to address and recognize the main depositional patterns produced in a rift basin. The main objective was to address the relative importance of climate changes and tectonics to the resultant stratigraphic architecture. The results of computer simulations of sedimentary basin fills of rift basins were quite useful to test working hypothesis and mimic the process of filling a half graben during a rift event. The studied section includes a neovalanginian-eobarremian (Lower Cretaceous) rift interval from the Pendência Formation, located in the southwestern portion of Umbuzeiro Graben, in the offshore Potiguar Basin. The depositional setting is interpreted as progradational deltaic system entering a lake from its flexural margin. Sismoestratigraphyc and well logs analyses allowed to interpret two regressive intervals (Green and Yellow Sequences), separated by a broad transgressive interval (Orange Sequence), known as the Livramento Shale. The depositional history encompass three stages: two tectonically active phases, during the deposition of the Green and Yellow Sequences, and a tectonically quiescent phase, during the deposition of the Orange Sequence. Paleoclimatic interpretation, based on quantitative palynology and geochemical data (��18O), suggests a tendency to arid conditions during the tectonically active phases and wet conditions during the tectonically quiescent phase. Stratigraphic modeling and backstripping techniques, supported by paleoclimatic/paleoecologic interpretations provide a powerful methodology to evaluate the tectonic and climatic controls on tectonic lakes

Atitudes e conhecimentos de agentes comunitários de saúde e suas relações com idosos

OBJETIVO: Analisar as relações entre agentes comunitários de saúde e os cuidados prestados a idosos. MÉTODOS: Estudo transversal descritivo, com 213 agentes comunitários das 12 unidades básicas de saúde e das 29 unidades de saúde da família de Marília em 2010. Os dados foram coletados por meio de um questionário sociodemográfico, um instrumento de escala de atitudes em relação à velhice (Escala de Neri) e um questionário para avaliar conhecimentos gerontológicos (Questionário Palmore-Neri-Cachioni). Para a análise dos dados, foi utilizado o programa Statistical Package for the Social Sciences versão 16.0 para Windows. RESULTADOS: Predominaram no quadro dos agentes comunitários os adultos jovens, do sexo feminino, casados, escolaridade > 12 anos e inseridos na atividade há mais de seis anos. A maioria dos agentes relatou experiência com grupo de idosos e convivência intradomiciliar com pessoas dessa faixa etária, porém menos da metade referiu capacitação no tema envelhecimento. As avaliações positivas dos agentes quanto às atitudes perante a velhice ocorreram principalmente em aspectos como a sabedoria e generosidade dos idosos, porém foram marcantes as atitudes negativas para lentidão e rigidez. O número de acertos sobre gerontologia foi baixo e esteve diretamente associado às capacitações recebidas pelos agentes. Foram observados estereótipos em relação ao idoso, na medida em que muitos agentes os consideravam insatisfeitos e dependentes. CONCLUSIONES: Mudar as atitudes e melhorar o conhecimento que se tem acerca do envelhecimento é essencial no enfrentamento das demandas advindas dessa fase da vida. Qualificar a formação do agente comunitário de saúde é fundamental no cuidado ao idoso na atenção primária.

Qualidade da carne de cordeiros confinados recebendo diferentes relações de volumoso: concentrado na dieta

Este estudo teve como objetivo avaliar a qualidade da carne de cordeiros terminados em regime de confinamento que receberam dietas com diferentes teores de concentrado. Foram utilizados 18 cordeiros ½ Ile de France ½ Santa Inês não castrados, com peso inicial de aproximadamente 15 kg, distribuídos em dois lotes, representados pelo tratamento 1 (T1) animais que receberam na dieta relação volumoso:concentrado de 35:65 e (T2) cordeiros que receberam relação volumoso:concentrado de 65:35 até atingirem 32 kg de peso corporal em regime de confinamento, peso pré-determinado para o abate dos animais. Os cordeiros do tratamento 1 e 2 apresentaram valores similares de pH, força de cisalhamento, perdas por cocção e capacidade de retenção de água da carne, com valores médios de 5,70, 1,03 kgf/cm², 35,20 e 59,31%, respectivamente. A relação volumoso:concentrado não influenciou na qualidade centesimal da carne dos cordeiros alimentados com dietas mais concentradas ou mais volumosas, para umidade, proteína, extrato etéreo e matéria mineral. Concluiu-se que os cordeiros terminados em confinamento recebendo diferentes teores de concentrado na dieta apresentaram qualidade da carne similar; portanto, a escolha da dieta vai depender do custo dos ingredientes no momento do confinamento.

Limiar anaeróbio e velocidade crítica determinada com diferentes distâncias em nadadores de 10 a 15 anos: relações com a performance e a resposta do lactato sanguíneo em testes de endurance

O objetivo deste estudo foi comparar a velocidade crítica (VC) determinada através de diferentes distâncias com o limiar anaeróbio (LAn) e as velocidades máximas mantidas em testes de 20 (V20) e 30 (V30) minutos na natação, verificando se a idade cronológica em jovens nadadores interfere nessas relações. Participaram do estudo 31 nadadores (17 meninas e 14 meninos) divididos segundo a idade cronológica em dois grupos: 10 a 12 anos e 13 a 15 anos. O LAn foi determinado como sendo a velocidade correspondente a 4mM de lactato sanguíneo. A VC1 (25/50/100m), VC2 (100/200/400m) e a VC3 (50/100/200m) foram calculadas através do coeficiente angular da reta de regressão linear entre as distâncias e seus respectivos tempos. As V20 e V30 foram determinadas através de três a seis repetições, com coletas de sangue no 10º minuto e ao final do tiro. Para o grupo de 10 a 12 anos, a VC1 (m/s) (0,98 ± 0,17) e o LAn (0,97 ± 0,12) não foram diferentes entre si, sendo maiores do que a VC2 (0,92 ± 0,16), VC3 (0,89 ± 0,18), V20 (0,92 ± 0,11) e V30 (0,90 ± 0,11). Para o grupo de 13 a 15 anos, a VC1 (m/s)(1,11 ± 0,11) foi maior do que o LAn (1,02 ± 0,07), V20 (0,99 ± 0,09), V30 (0,97 ± 0,09), VC2 (0,98 ± 0,11) e VC3 (1,00 ± 0,11). Pode-se concluir que a distância utilizada na determinação da VC interfere no valor obtido, independente da idade cronológica. A VC determinada com distâncias entre 50 e 400m pode ser utilizada na avaliação da capacidade aeróbia de crianças e adolescentes, substituindo os testes contínuos máximos com durações próximas a 20 ou 30 minutos.
