Le present travail a pour objectif, discuter le dialogue entre deux des formes de penser le processos santé-maladie: la médécine traditionnelle et celle scientifique. Et cette dernière représentée par le Système Unique de Santé, particulièrement par une Équipe de Santé de la Famille. Partant du questionnement “quel est le rôle de chaque système de santé dans les problèmes sanitaires ainsi que dans la prévention des maladies?”, il s‟agit de vérifier si l‟ ”Écologie des Savoirs” discutée par Santos (2007) a été appliquée dans les deux manières de penser et pratiquer les politiques de santé; tenant em compte que chacune d‟elles ayant son champ de possibilites et d‟impossibilités agit directement sur le quotidien des aires géographiques concernés par la recherche: le District de São João do Abade dans le Municipe de Curuçá/PA et l‟Équipe de Santé de la Famille Abade localisée dans ce même district. Cette étude fut réalisée à partir d‟instruments de collecte de données comme la recherche de terrain, l‟observation directe et les interviews semi-structurés (HAGUETTE, 1997) e apports théoriques à partir de certains des concepts clés les plus utilisés par les Épistémologies du Sud où nous mettons en relief l' “Écologie des Savoirs” (Santos, 2007); le “travail de Traduction” (SANTOS, 2008); la “Sociologie des Absences et la Sociologie des Émergences” (SANTOS, 2004); le concept de “Santé-Maladie” (MINAYO, 1988); ainsi que les discussions autor des “Savoirs de la Tradition” (ALMEIDA, 2010; RAMALHO et ALMEIDA, 2011). La stratégie “Santé de la Famille fut pensée à travers la vision de Guedelha (2008) et Vilar et al. (2011) où à partir de cette dernière la discussion sur le concept de “Médécine Communautaire” (DONNANGELO e PEREIRA, 1976) comme recours importante dans la recherche de l‟ “Écologie des Savoirs” dans la Stratégie Santé de la Famille a été possible.

Feeding is the primary selective pressure in all forms of animals. Nutritional ecological models predict consequences of preferred and non-preferred food consumption on behavioural, physiological and morphological adaptations. At same time, socioecological models infer socio-organizarion patterns based on feeding competition faced by animals. A list of preferred foods, and inferences regarding the intensity of feeding competition and its behavioural consequences are information of much importance for management of populations in fragments. In this work we observed the feeding behavior and spatial positioning of a group of more than 100 blond capuchin monkeys (Sapajus flavius) that inhabit a fragment of Atlantic forest, surrounded by sugarcane plantation. We compared the consumption of different food items with their monthly availability in the area to define the preferred and fallback food items. We recorded the vocalizations of aggression and the inter-individual distance (area of Minimum Convex Polygon/n individuals) to infer the type of food competition experienced by animals. In the year studied the fruit feeding time correlated with top consumed fruit productivity, indicating preference for fruits. Our data indicate that the species Elaeis sp., Cecropia palmata, Inga spp. and Simarouba amara are the preferred food items in the diet. Available all year round and uniformly distributed, sugarcane was a regular item in the diet and its was characterized as a staple fallback food for this group. Although fruits are preferential food items, direct competition rate did not correlate to fruit productivity in the area, maintaining the high rates throughout the year (2.45 events/ hour). The inter-individual distance index positively correlated with rain fall indicating scramble food competition. The number of neighbours of females carrying infants was smaller when fruit productivity is low, indicating that females carrying infants are suffering increased indirect competition. Our data indicates that blond capuchins in this fragment make use of sugar cane as a staple fallback food, which evidence the importance of sugar cane landscape for the survival of this critically endangered capuchin species in fragmented habitats in Northeast Brazil. A preliminary list of preferred and important foods is offered, and can assist in the choice of trees for reforestation, better fragments to be preserved and areas of release and translocation of animals. We did not observe an increase of contest competition while using preferred foods, but when using staple FBF. This may be due the altered environment, which results in high competition food throughout the year. Both the food preference as the social and behavioral consequences of high food competition experienced by animals in this fragment must be accompanied over the years to ensure the survival of this population.

O ser humano vive maior parte do seu tempo em contato direto com o ambiente construído, portanto tornou-se fundamental pesquisar as relações de alteridade, qualidade de vida e pertencimento dentro de um espaço específico, a casa. Ressaltando que a casa nesta pesquisa é todo e qualquer lugar de moradia, percebe-se que ela exprime um estilo de vida, ou seja, um modo de viver e conviver, de pensar, de sentir, e de se relacionar com as pessoas e com o espaço. A partir das relações de seis moradores do Município de Rio Grande com suas respectivas casas pudemos conhecer os processos que ali ocorrem e quais são os efeitos deles na vida e atitudes de cada morador dentro e fora da morada. O estudo é fundamentado primordialmente na Educação Ambiental e na Ecologia Onírica. Mais especialmente, na Educação Estética Ambiental e Educação Estética Onírica, porém também dialoga com outras áreas do conhecimento, como a Psicologia Ambiental. Esta avalia e compreende o homem, como ele reage, interpreta e sente os espaços, e consequentemente, como ele é constituído através de todas as experiências, vivências, memórias neste meio tão íntimo que é a casa de cada um. O objetivo da pesquisa foi, a partir das relações dos moradores entre si e com o espaço da casa, conhecer qual é o significado desta na vida dos seus moradores, despertar a valorização do espaço/morada e o sentimento de pertencimento a ela, promovendo através dessa consciência uma maior qualidade de vida dentro e fora de casa.

A Área de Proteção Ambiental da Lagoa Verde é composta por um mosaico de unidades ambientais. Entre elas, destaca-se um fragmento de mata de restinga que reúne características físicas e microclimáticas para o estudo de ecologia de briófitas. Este estudo teve por objetivo realizar o levantamento das espécies de briófitas; fornece novas ocorrências de briófitas para o Rio Grande do Sul; avaliar a influência dos gradientes longitudinal e vertical na distribuição de briófitas; quantificar a variação da diversidade de briófitas nos gradientes longitudinal e vertical. Foram identificadas 51 espécies de briófitas como novas ocorrências para o Rio Grande do Sul, sendo 11 musgos e 40 hepáticas. Além do local de estudo foram identificadas espécies que estavam no herbário SP. No estudo dos gradientes longitudinal e vertical foram identificadas 53 espécies de briófitas, sendo 17 musgos e 36 hepáticas. Através da análise dos transectos e da inclusão dos forófitos subdivididos em três zonas de altura, foram coletadas amostras terrícolas e corticícolas. As briófitas respondem aos gradientes, através dos fatores microclimáticos (luminosidade e umidade), em relação ao aumento da riqueza e mudança na composição de espécies. A partição aditiva da diversidade de briófitas quantificou a variação da composição de espécies em cada gradiente. A diversidade entre cada nível dos gradientes longitudinal (umidade) e vertical (luminosidade) variou em torno de 40% e 50%, respectivamente. Em conclusão, o estudo sobre a ecologia de briófitas gerou conhecimento sobre a diversidade e biogeografia das espécies; contribuiu para o entendimento da distribuição das briófitas em função dos gradientes longitudinal e vertical, por influência de fatores microclimáticos e; revelou a variação da composição de espécies em função dos gradientes horizontal (umidade) e vertical (luminosidade).

O estudo teve como objetivo descrever a biologia reprodutiva e a dieta de populações de Thamnodynastes hypoconia em ambientes úmidos subtemperados do extremo sul brasileiro. Para avaliação da reprodução foram feitas análises macroscópicas das gônadas. Para avaliação da ecologia alimentar foram empregadas análises de conteúdo estomacal e de isótopos estáveis (δ13C e δ15N). Os machos apresentaram maior comprimento rostro-cloacal que as fêmeas e atingiram a maturidade sexual com menor tamanho corporal. O ciclo reprodutivo das fêmeas foi sazonal, com vitelogênese secundária ocorrendo entre o inverno e a primavera. Os machos apresentaram ciclo contínuo. Aparentemente a cópula ocorre entre o final da primavera e o início do verão, quando foram detectados embriões nas fêmeas e a parturição ocorreu no verão. Não houve relação entre o tamanho da ninhada e o tamanho da fêmea, e a frequência reprodutiva de 40% foi considerada relativamente baixa. Todavia, por ser uma espécie dominante em banhados subtemperados do extremo sul do Brasil sua estratégia reprodutiva parece ser eficiente. Dessa forma, o ciclo contínuo dos machos, bem como a viviparidade possam potencializar o deslocamento do pico reprodutivo da população de modo a ajustar-se de acordo com os picos de temperatura do ambiente. A análise de conteúdo estomacal mostrou uma dieta predominantemente anurófaga, exceto por um único lagarto. Hylidae foi a família mais representativa, com predomínio de Hypsiboas pulchellus, seguida de Leptodactylidae, onde Leptodactylus latrans teve maior importância. As análises de isótopos estáveis corroboraram a importância dessas espécies na alimentação da serpente. Apesar de ser uma serpente terrestre, T. hypoconia apresentou assinatura isotópica mais próxima das fontes primárias oriundas do ambiente aquático, o que indica a importância das áreas alagáveis para a subsistência de organismos terrestres de habitats adjacentes.

The feeding habits and biological aspects of the reproductive cycle of two-spot astyanax, Astyanax cf. lacustris (Reinhardt, 1874) were investigated. Fish samples were captured on a monthly basis, using gillnets of 4 cm mesh size, from the Piató Lake, Assu, Rio Grande do Norte, during the period of September, 2006 to August, 2007. Physico-chemical parameters, such as, temperature, electrical conductivity and dissolved oxygen of the lake were registered. The monthly values of rainfall also were obtained. The 360 individuals captured, were measured, weighed, dissected, and stomach weight and the stage of gonadal maturity were registered. The stomach contents analyses were carried out based on volumetric method, points, frequency of occurrence and applying the Index of Relative Importance. The degrees of repletion of the stomachs were determined besides the Index of Repletion relating to feeding activity variations and frequency of ingestion with limnological parameters and rainfall. The food items identified were separated into distinct groups according to their origin. Sex ratio and Gonadosomatic Relation of females were verified to determine the spawning period and fecundity. The physico-chemical parameters presented the following annual mean values: temperature = 28.8ºC, electrical conductivity = 992.5 µS.cm-1; dissolved oxygen = 4.9 mg.L-1 during the study period. The annual mean of the rainfall was 63.5 mm. The results indicate that this species present an omnivorous feeding habit with a tendency towards insectivory, with an increase in feeding activity during the dry season. The aquatic oxygen to interfere very importance in the feeding activity than the others factors physico-chemicals of water and rainfall. There was a predominance of females, with a sex proportion of 1M:7F. The macroscopic characteristics of the ovaries and testicles revealed four stages of gonadal development: immature, maturing, mature and spent. A temporal variation was observed for the gonadal development of males and females. There was reproductive activity through out the year, with peaks in the months of February, April and June to correspond with the rain of precipitation of the region. The mean fecundity was 7.681 mature oocytes, varying from 4.476 to 12.036, with mean of 7.681. There was positive relation between fecundity and body mass. Condition Factor is not an efficient indicator of the reproductive period of this species. The species A. cf. lacustris is an opportunist and is well adapted to the conditions of the semi-arid Caatinga Biome

The Caatinga biome is rich in endemic fish species fauna. The present study the results of fish faunal surveys conducted in the hydrographic basin of Piranhas-Assu of the Brazilian Caatinga biome. The fish samples collected were distributed in four orders (Characiformes, Perciformes, Siluriformes and Synbranchiformes), 11 families (Characidae, Curimatidae, Auchenipteridae, Anostomidae, Prochilodontidae, Erythrinidae, Cichlidae, Sciaenidae, Heptapteridae, Loricariidae, Synbranchidae) and 22 species, of which 17 are endemic and five have been introduced from other basins. The order Characiformes was the most representative in number of species (46,35% ) followed by Perciformes (35,38%), Siluriformes (17,44%) and Synbranchiformes (0,5%). The Nile tilapia, Oreochomis niloticus, the only exotic species, was most expressive in number of individuals (24.92%) followed by the native species piau preto, Leporinus piau (18,77 %). Considering the relative frequency of occurrence of the 22 species, 13 were constant, five were accessory and four were occasional. This study investigated the reproductive ecology of an endemic fish black piau, Leporinus piau from the Marechal Dutra reservoir, Acari, Rio Grande do Norte. Samplings were done on a monthly basis from January to December 2009, and a total of 211 specimens were captured. The environmental parameters such as rainfall, temperature, pH, electrical conductivity and dissolved oxygen of water were recorded. The sampled population showed a slight predominance of males (55%), however females were larger and heavier. Both sexes of L. piau showed positive allometric growth, indicating a higher increase of weight than length. The first sexual maturation of males occurred at smaller size, with 16.5 cm in total length than females (20.5 cm). During the reproductive period, the condition factor and gonadosomatic index (GSI) of L. piau were negatively correlated. This species has large oocytes with a high mean fecundity of 54.966 with synchronous oocyte development and total spawning

The reproductive ecology of fish plays a key role both for rational exploitation methods and for protective measures of natural stocks. The purpose of this study was to analyze the reproductive aspects of the damsel-fish, Stegastes fuscus, during October 2004 to September 2005, in the coastal rocky reefs of Búzios Beach, Nísia Floresta, RN. Fish were captured using hooks and hand nets, during low tide. Reproduction was determined using sexual ratio, mean length of first maturation (L50), absolute fecundity and macroscopic characteristics of gonads. The following parameters were related to gonadosomatic index (GSI): condition factor (CF), hepatosomatic index (HSI), rain fall and temperature. In relation to sex distribution, it was observed that 78% were females and 22% were males. The L50 was 6.2 cm for females and 7.0 for males. Average fecundity was 6832 oocytes. Results showed that S. fuscus had better body condition in the months prior to spawning, particularly during initial and intermediate stages of maturation. Five stages of gonadal maturation were identified through macroscopic analysis: immature, in maturation, mature, spent and resting. The HSI was inversely related to the GSI. This was possibly due to the reproductive cycle of this species which was associated to the dry period of this region. During this period, low rain fall and high temperatures provide an propitious reproductive condition for the study species

En El Salvador, las Casas de Corredores de Bolsa, surgieron con el propósito de facilitar la intermediación bursátil de compra y venta de títulos valores, a través de la bolsa de valores, quién facilita las negociaciones de mercado primario, secundario, internacional y reportos a través de títulos valores como lo son las acciones, Euro bonos, letes, certificados de inversión, y otros instrumentos de inversión inscritos en la Bolsa de Valores de El Salvador y el registro público de la Superintendencia del Sistema Financiero. Esto contribuye con el desarrollo económico del país y la sociedad en general, sirviendo de intermediarios entre el emisor y el inversionista, canalizando los recursos hacia los sectores productivos para desarrollar proyectos, para capital de trabajo o simplemente para refinanciar deudas. Dichas Casas de Corredores de Bolsa realizan operaciones bursátiles bajo la fiscalización de la Superintendencia del Sistema Financiero. El Marco Regulatorio en El Salvador se ha ido adecuando para desarrollar un mercado dinámico y organizado dentro de un ambiente de libre competencia, con intermediarios autorizados; las disposiciones regulatorias de este sector se encuentran contenidas dentro de leyes tributarias emitidas por el Ministerio de Hacienda y normativa financiera emitidas por el Banco Central de Reserva de El Salvador. A raíz de la aprobación de la Ley de Impuesto a las Operaciones Financieras, el mercado bursátil, sufrió impacto por la aplicación en la implementación de las principales transacciones que se desarrollan dentro de dicho mercado. El impacto que han sufrido las Casas de Corredores de Bolsa, se ve reflejado en la disminución de los ingresos, los costos se incrementaron, el volumen de operaciones fue reducido considerablemente, durante los meses de septiembre a diciembre del año 2014; así como también las horas del personal que trabaja en las Casas de Corredores de Bolsa, se aumentaron. El mercado primario es el menos afectado, debido a que al invertir el cálculo del impuesto se hace únicamente por las comisiones generadas por operaciones de compra y venta, lo cual es un atractivo para los inversionistas en comparación con los otros mercados. La negociaciones en el mercado secundario ha sido las más afectadas, por la implementación de la Ley de Impuesto a las Operaciones Financieras, debido a que las transacciones de venta se hace el cálculo de las comisiones generadas por cada operación, en las compras es por el valor transado, más las comisiones; lo cual al momento de efectuar el pago de este impuesto afecta al inversionista, disminuyendo su margen de rendimiento e incrementando sus costos, Para la implementación de la Ley de Impuesto a las Operaciones Financieras, Se hace necesario que las Casas de Corredores de Bolsa, elaboren procedimientos internos, y para eso es necesario incrementar las horas hombre, y aumento en gastos de papelería y otros, para así poder cumplir con todas las exigencias en su aplicación en las principales transacciones que estas realicen
