Pesquisa do Estado da Bahia - FAPEB / The present study has as main objective the research on educational processes in the Museu Casa do Sert?o, belonging to the Universidade Estadual de Feira de Santana, in the analysis of the expository route of guided tours. To this end, we used a process of qualitative research with semi-structured interview, questionnaire, analysis of some documents and some observations from the exhibitions. The theoretical framework is constructed according to Certeau's ideas (1996), Canclini (2013), Albuquerque (2011), Cury (2006) among other authors. The discourse of its creator, Eurico Alves Boaventura, is very present in the exhibition, but it also coexists with some elements of modernity in the use of certain industrialized materials present in some objects. The historical perspective is striking in the exhibition, though the exhibits focus on other issues such as, for example, man's relationship with nature. These discursive elements relate to other discursive productions on the Brazilian Northeast accentuating a cultural repertoire that produces a scenario typically propagated by the media. In addition, there was a didactical trend in your exhibitions, assuming that the most of public of this Museum is scholar. / O presente estudo tem como objetivo principal a investiga??o sobre as a??es pedag?gicas do Museu Casa do Sert?o, pertencente ? Universidade Estadual de Feira de Santana, procurando analisar o percurso expositivo das visitas guiadas. Para tanto, utilizou-se um processo de pesquisa qualitativa com entrevista semi-estruturada, question?rio, an?lise de documentos da institui??o e observa??es das exposi??es. O referencial te?rico est? constru?do de acordo com as ideias de Certeau (1996), Canclini (2013), Albuquerque J?nior (2011), Cury (2006) entre outros autores. O discurso do seu idealizador, Eurico Alves Boaventura, est? bastante presente nas exposi??es, mas ele tamb?m convive com alguns elementos da modernidade na utiliza??o de determinados materiais industrializados presentes em alguns objetos. A perspectiva hist?rica ? marcante nas exposi??es, embora elas versem sobre outros assuntos como, por exemplo, a rela??o do ser humano com a natureza. Estes elementos discursivos se relacionam com outras produ??es discursivas sobre o Nordeste acentuando um repert?rio cultural que produz um cen?rio tipicamente veiculado pela m?dia. Al?m disso, observou-se uma tend?ncia didatizante nas exposi??es, levando em considera??o que a maior parte do p?blico do Museu ? escolar.

Para isso, levou-se em considera??o indicadores socioecon?micos como: participa??o em cooperativas, associativismo, aspectos administrativos e de controle da produ??o, destino e pre?o dos produtos produzidos, custo da produ??o, principais problemas enfrentados pela atividade realizada, entre outros. A coleta de dados foi realizada durante o per?odo da seca, atrav?s de aplica??o de question?rios com 30 produtores da regi?o e os dados coletados foram analisados atrav?s da estat?stica descritiva. Espera-se promover a consolida??o dessa metodologia, com a integra??o entre os outros indicadores de sustentabilidade para a avalia??o dos sistemas de produ??o animal e a sua utiliza??o para apoiar pol?ticas p?blicas, al?m de promover um desenvolvimento rural sustent?vel e a compreens?o de sua complexidade. / This project aims to evaluate the vulnerability of family farming that produces milk in Serid? Potiguar, analyzing and understanding the factors that influence it. The study was based on vulnerability analysis chart developed by Turner et al (2003a) , in which the vulnerability involves not only the exposure to hazards , but also the sensitivity and resilience of the system . Data collection was conducted between the months of May and June, in 2013, through questionnaires with 30 producers in the region. Data were tabulated in spreadsheets and analyzed using descriptive statistics and cluster analysis. High levels of exposure and sensitivity were found, as well as a low level of resilience. The result of the study shows that the system is considered at a high level of vulnerability, but the final average found is located very close to the boundary between low and high, showing that there is still a great opportunity to reverse this situation if necessary changes begin to be made in time. It is necessary to continue studies to monitor developments in this situation of vulnerability, identifying of risk categories for which alternatives are consistent with the real needs of producers, seeking to promote a local socioeconomic development and moving toward sustainability of the whole system in the short, medium and long term.

Durante o processo de envelhecimento, ocorrem altera??es fisiol?gicas que levam uma diminui??o na velocidade de processamento cerebral. Nos ?ltimos anos a realidade virtual (RV), vem se ampliando cada vez mais aplicada nos centros de reabilita??o, portanto conhecer a influ?ncia da RV sob a atividade cerebral, nessas popula??es se faz necess?rio. Dentro desse contexto, a Eletroencefalografia ? considerada como um dos principais meios de capta??o da atividade cerebral. Atrav?s da obten??o da atividade cerebral, podemos estud?-la de diversas formas, uma delas ? o estudo de coer?ncia entre pares de eletrodos, permitindo analisar as rela??es de diferentes ?reas cerebrais e como estas trocam informa??es. Objetivo: Este estudo teve por objetivo, investigar a influ?ncia imediata da exposi??o a uma sess?o de treino de equil?brio em ambiente virtual sobre a coer?ncia entre os lobos frontais de adultos jovens e idosos, mensurada atrav?s do Emotiv EPOC. Metodologia: Estudo comparativo, envolvendo 20 indiv?duos divididos nos grupos: jovem (GJ) e idoso (GI). Ap?s passarem por uma avalia??o do estado geral, do suporte necess?rio para a marcha (FAC) e do estado cognitivo (MEEM), os participantes realizaram durante 4 minutos, o jogo penguin slide da categoria de equil?brio do Nintendo Wii, cujos efeitos sobre a atividade cortical foram observados por meio da coleta realizada pelo EPOC. Resultados: O GJ apresentou valores de coer?ncia inter-hemisf?rica semelhantes na banda alfa e na banda beta em compara??o ao GI. Quanto a coer?ncia de fase o GI apresentou uma antecipa??o do hemisf?rio direito enquanto, o GJ apresentou do hemisf?rio esquerdo. Conclus?o: A realidade virtual parece estimular igualmente o GJ e o GI. Entretanto o GJ, apresentou padr?es de ativa??o e de coer?ncia de fase, que sugerem compatibilidade com aprendizado pr?vio ? RV, justificando as diferen?as encontradas na coer?ncia de fase entre os grupos. / Introduction: During the aging process, physiological changes occur that lead to a decrease in brain processing speed. In recent years virtual reality (VR) has been increasingly applied in rehabilitation centers, so knowing the influence of VR under brain activity, in these populations is necessary. Within this context, Electroencephalography is considered as one of the main means of capturing brain activity. By obtaining the brain activity, we can study it in several ways, one of them is the study of coherence between pairs of electrodes, allowing to analyze the relations of different brain areas and how they exchange information. Objective: This study aims to investigate the immediate influence of exposure to a balance session in a virtual environment on the coherence between the frontal lobes of young and old adults, measured using Emotiv EPOC. Methodology: A comparative study involving 20 individuals divided into the groups: young (GJ) and elderly (GI). After undergoing an evaluation of the general condition, the necessary support for the gait (FAC) and the cognitive state (MEEM), the participants performed during 4 minutes, the penguin slide game of the balancing category of Nintendo Wii, whose effects on the activity Were collected through COPD. Results: The GJ presented similar inter-hemispheric coherence values in the alpha band and in the beta band in comparison to the GI. Regarding phase coherence, the GI presented an anticipation of the right hemisphere while, the GJ presented of the left hemisphere. Conclusion: Virtual reality seems to stimulate both GJ and GI. However, the GJ presented patterns of activation and phase coherence, which suggest compatibility with prior learning to VR, justifying the differences found in phase coherence between the groups.

Na atualidade, uma das t?cnicas que tem permitido o monitoramento da atividade cerebral ? a eletroencefalografia a partir de interfaces n?o-invasivas e wireless. Estudos envolvendo EEG t?m investigado a rela??o entre altera??es nos padr?es de ativa??o cerebral e mudan?as no comportamento do indiv?duo. No entanto, pouco se sabe acerca do comportamento da ativa??o cerebral durante tarefas motoras e de que forma esta ativa??o ? caracterizada em ambientes virtuais ou reais.Objetivo: Investigar o comportamento do potencial de ativa??o das ondas theta, alpha, beta e gamma de adultos jovens saud?veis durante uma tarefa motora para membros inferiores em um ambiente virtual e em um ambiente real. Metodologia: Estudo cross-over, no qual 10 jovens saud?veis foram submetidos a uma avalia??o eletroencefalogr?fica durante a execu??o de tarefa de subir e descer um degrau no ambiente virtual (jogo basic step do Nintendo Wii) e em ambiente real, ambas com dura??o de 1 minuto. Os dados foram analisados atrav?s dos testes de Wilcoxon e o teste t?Student de amostras dependentes.Resultados: Descritivamente, a atividade de theta e alpha foi maior em ambiente real e a atividade de beta e gamma foi maior em ambiente virtual. O ambiente virtual promoveu maior ativa??o do hemisf?rio direito e de canais ?ntero-frontais bilateralmente. Al?m disso, na frequ?ncia theta, a regi?o occipital direita foi mais ativada em ambiente real do que virtual (p<0,05). Conclus?o: O comportamento do potencial de ativa??o das ondas theta, alpha, beta e gamma observado durante a execu??o de uma tarefa motora apresenta-se de forma vari?vel em fun??o do ambiente que o indiv?duo est? sendo exposto - real ou virtual. Dessa forma, ressalta-se a implementa??o de estudos futuros que promovam embasamento para tomada de decis?o cl?nica de forma que a escolha do ambiente terap?utico (real ou virtual) seja de acordo com as ?reas cerebrais que se objetiva ativar. / Introduction: Brain activity is defined as the propagation of electrical impulses in order to promote a functional integration of the brain. Electroencephalography is one of the techniques that allows brain activity?s monitoring by using non-invasive and wireless interfaces. Studies involving EEG have investigated the relationship between changes in patterns of brain activity and in individual behavior. However, knowledge about brain activity during motor tasks and how this activity is characterized in virtual or real environments is still unclear. Objective: Compare theta, alpha, beta and gamma power in healthy young adults during a lower limb motor task performed in a virtual and real environment. Methodology: Cross-over study in which 10 healthy young adults were subjected to an EEG assessment while performing a one-minute task consisted of going up and down a step in a virtual environment (performed by the virtual game ?Basic step?) and real environment. Wilcoxon and t'Student tests were executed to analyze data. Results: Descriptively, theta and alpha power were higher in real environment while beta and gamma power were higher in virtual environment. Virtual environment caused greater activation of the right hemisphere and anterior-frontal channels bilaterally. Furthermore, in theta frequency, the right occipital region?s activity in real environment was higher than in virtual environment (p <0.05). Conclusion: Theta, alpha, beta and gamma power observed while performing a motor task present variation according to environment in which the individual is being exposed - real or virtual. Thus, we emphasize the implementation of future studies in order to promote basis for clinical decision-making so that the choice of the therapeutic environment (real or virtual) would be according to the brain areas that are in need for activation.

Objective - The main objective of this thesis was to investigate the influence of an exercise protocol, based on virtual reality, on PB and QOL of pregnant women. Methodology - Randomized controlled clinical trial with a sample of 57 pregnant women divided into a control group (CG = 29) and an experimental group (EG = 28). Sociodemographic, clinical and obstetric information was collected, was evaluated the PB (Balance Master System?) and Wii Fit Plus? was used to train this body function. The evaluation of the quality of life was carried out through the Quality of Life Index of Ferrans and Powers. The CG participated in 12 meetings of the Preparatory Course for Gestation, Childbirth and Postpartum (PCGCP). The GE attended the PCGCP and, simultaneously, performed the training protocol, based on RV, which consisted in the execution of 5 games for postural balance, during 12 individual sessions, held three times a week. For statistical analysis were used Student's t-tests for independent samples, Mann-Whitney, Chi-square and repeated measures ANOVA (2x2). Results - The main result of this study was that there were no intra and intergroup differences for PB (P> 0.11) and QoL (P = 0.20), indicating maintenance of these variables with the progress of pregnancy and through the implementation of the two proposed interventions. Conclusion - The results suggest that health education interventions and training with Wii Fit Plus? prevent worsening of postural balance and quality of life, expected with the onset of the pregnancy period.

It contains the doctrine of sensitivity responsible for the intuitions, which rests on the concepts of space and time, and, with this, the tematiza??o of two important questions. For Kant s philosophy in its epistemologic source what s the importance of the concepts of and time? How these concepts of space and time inscribe themselves with such statute as an investigatory task of metaphysics? The specification of the concepts of space and time as ingredients of the theories treated and enrolled in this work are segmented of the Aesthetic transcendental of Kant, and interpreted under Strawson s light. The research is divided in two chapter; first, constituted of two parts, the first part presents an introduction to the Aesthetic transcendental of Kant, to show the doctrine of the sensitivity which is part of with its forms space and time, authentic forms of the intuition. The second chapter, is constituted of four parts, that deal with the interpretation of the austere model of Strawson and related with Kant s transcendental Aesthetic. The conclusion of our work, about the declared objection of Strawson in its austere interpretation that refuses the idea of space and time, even keeping its a priori character, cannot be accepted.

Cognitive-Behavioral Therapy (CBT) is one of the most effective therapeutic approaches for PTSD. Although effective, some patients are refractory to imaginal exposure, a frequently used thecnique in CBT for PTSD, and there is a high dropout rate. In order to increase therapeutic efficacity and treatment adherence, Virtual Reality (VR) devices have been developed since 1990 to be used in Virtual Exposure Therapy (VET). This therapy is a variation of CBT therapeutic interventions that have been showing good outcomes. However, most researches in this area study military populations or victims of terrorist attacks. Few studies have been found in literature review about the treatment of victims of urban violence, a very common type of trauma in developing countries such as Brazil. Still, some occupations are more exposed to violence, as is the case of bank employees. The objective of this study is to evaluate posttraumatic reactions in victims of bank robberies and the efficacy of VET in the treatment of PTSD. This study is composed of (1) an introduction to the main concepts used to develop this research; (2) a theoretical review of the advantages and disadvantages of VET in the treatment of PTSD; (3) an empirical section on an assessment of posttraumatic reactions on bank employees victims of bank robberies who sought psychological care; (3) a presentation of a VET protocol for victims of bank robberies who develop PTSD; (4) an evaluation of the proposed treatment protocol through a case study of a bank employee with PTSD and (5) final considerations of the main findings of this work. The results suggest that bank employee?s victims of robberies who sought psychological care present an elevated percentage of psychiatric disorders. Among them, PTSD is the most frequent. In the case study performed, the VET protocol proved to be efficient, with reduction of posttraumatic, depressive and anxiety symptoms. / O Transtorno de Estresse P?s-Traum?tico (TEPT) ? um transtorno mental que pode se desenvolver a partir da exposi??o a um evento traum?tico. Suas caracter?sticas s?o a reviv?ncia do trauma, evita??o de situa??es que relembrem o evento ou provocam ansiedade, altera??es negativas nas cogni??es e humor, e excitabilidade aumentada. A Terapia Cognitivo-Comportamental (TCC) ? uma das abordagens terap?uticas com maior efic?cia no tratamento do TEPT. Apesar de eficaz, alguns pacientes s?o refrat?rios ?s t?cnicas de exposi??o atrav?s da imagina??o frequentemente usadas na TCC para o TEPT, e o percentual de abandono do tratamento ? elevado. Visando ao aumento da efic?cia terap?utica e uma maior ades?o ao tratamento, v?m sendo desenvolvidos desde a d?cada de 1990 dispositivos de Realidade Virtual (RV) que possam ser utilizados para realiza??o da Terapia de Exposi??o Virtual (TEV). Esta terapia ? uma varia??o das interven??es terap?uticas tradicionalmente utilizadas na TCC e tem apresentado bons resultados. Por?m, a maior parte dos estudos nesta ?rea explora popula??es militares ou v?timas de ataques terroristas. Poucos estudos s?o encontrados sobre o tratamento de v?timas de viol?ncia urbana, um tipo de trauma muito frequente em pa?ses em desenvolvimento como o Brasil. Ainda, profissionais de algumas ?reas est?o mais expostos ? viol?ncia, como ? o caso dos banc?rios. O objetivo deste estudo ? avaliar as rea??es p?s-traum?ticas em banc?rios v?timas de ataques a banco e a efic?cia da TEV no tratamento do TEPT desenvolvido a partir deste trauma. Esta tese ? composta de (1) uma introdu??o aos principais conceitos utilizados no desenvolvimento desta pesquisa; (2) uma revis?o te?rica sobre as vantagens e desvantagens da utiliza??o da TEV no tratamento do TEPT; (3) um se??o emp?rica sobre a avalia??o de rea??es p?s-traum?ticas em banc?rios v?timas de assaltos a banco que buscaram atendimento psicol?gico; (3) a apresenta??o de um protocolo de TEV para v?timas de assaltos a banco que desenvolveram TEPT; (4) a avalia??o da efic?cia do protocolo de tratamento proposto atrav?s do estudo de caso de uma banc?ria portadora de TEPT e (5) considera??es finais compilando os principais achados deste trabalho. Os resultados encontrados indicam que banc?rios v?timas de ataques a banco que buscaram atendimento psicol?gico apresentam um elevado percentual de transtornos psiqui?tricos. Entre eles, o TEPT ? o mais frequente. No estudo de caso realizado, a TEV proposta se mostrou eficaz, com redu??o significativa dos sintomas p?s-traum?ticos, depressivos e de ansiedade.

Estudo transversal desenvolvido com 180 indiv?duos adultos e idosos com idade entre 18-80 anos, ambos os sexos, com diagn?stico de s?ndrome metab?lica, segundo os crit?rios do National Cholesterol Education Program Adult Treatment Panel III (NCEP-ATP III). Foi considerada como vari?vel dependente a concentra??o de 25OHD; e como vari?veis independentes: idade, sexo, cor da pele, uso de filtro solar, fototipo de pele, escore de exposi??o solar, ?ndice de radia??o ultravioleta (IRUV), localiza??o geogr?fica, esta??es do ano, ?ndice de massa corporal (IMC), rela??o cintura-quadril (RCQ), circunfer?ncia da cintura (CC), paratorm?nio (PTH), c?lcio total s?rico, al?m do c?lcio e vitamina D da dieta. Potenciais preditores para a magnitude do status de 25OHD foram investigados por meio de 16 modelos de regress?o linear univariado, e sete modelos de regress?o m?ltipla. Foram estabelecidas medidas de associa??o e correla??o. O n?vel de signific?ncia adotado foi 5%. O status de 25OHD foi significativamente diferente entre inverno e ver?o (P=0,017). A m?dia de 25OHD indicou insufici?ncia no inverno (25,89ng/mL+7,61) e sufici?ncia no ver?o (31,81ng/mL+10,22), com aumento de 5,59ng/mL no ver?o. No modelo de regress?o linear simples, a concentra??o de 25OHD associou-se significativamente com o ver?o (P=0,003), de modo que a vari?vel esta??o do ano explicou 4,2% da variabilidade do status de 25OHD. O escore de exposi??o solar foi significativamente associado com a concentra??o de 25OHD (P=0,008), explicando 3,4% da variabilidade. No modelo de regress?o m?ltipla, sexo (P=0,027), RCQ (P=0,027), escore de exposi??o solar (P=0,006) e inverno vs. ver?o (P=0,004), explicaram 10,4% da varia??o da concentra??o de 25OHD. Os homens tiveram a concentra??o de 25OHD 3,71ng/mL maior do que as mulheres. O aumento de 1,0 unidade no escore de exposi??o solar, resultou no acr?scimo de aproximadamente 0,16ng/mL na concentra??o de 25OHD. A RCQ teve associa??o inversa com a concentra??o de 25OHD. A esta??o do ano ver?o e a exposi??o solar influenciaram no status de 25OHD dos indiv?duos com s?ndrome metab?lica residentes de uma regi?o do Brasil com elevados ?ndices de radia??o ultravioleta. / The risk of metabolic syndrome can be influenced by inadequate vitamin D levels, and exposure to sunlight is the main external source of vitamin D. This study assessed the influence of environmental, biological and nutritional factors as a function of seasons on the 25OHD status among individuals with metabolic syndrome. A cross-sectional study was developed with 180 adult and elderly individuals of both genders, between 18-80 years of age, with metabolic syndrome according to the National Cholesterol Education Program Adult Treatment Panel III (NCEP-ATP III) criteria. The 25OHD concentration was considered dependent variable; the independent variables were age, gender, skin color, use of sunscreen, skin type, sun exposure score, ultraviolet index (UVI), geographic location, season, body mass index (BMI), waist-hip ratio (WHR), waist circumference (WC), parathyroid hormone (PTH) level, total serum calcium level, and diet levels of calcium and vitamin D. The potential predictors for the 25OHD levels were investigated using 16 univariate linear regression models and seven multiple regression models. Measures of association and correlation were established and statistical significance was assumed for P < 0.05 (5%). The 25OHD status differed significantly between winter and summer (P = 0.017). The average 25OHD level was insufficient during the winter (25.89 ? 7.61 ng/mL) and sufficient during the summer (31.81 ? 10.22 ng/mL), with an increase of 5.59 ng/mL in the summer. In the simple linear regression model, 25OHD concentration was significantly associated with the summer season (P = 0.003); the season variable explained 4.2% of the variability in 25OHD concentration. The sun exposure score was significantly associated with 25OHD concentration (P = 0.008), explaining 3.4% of the variability. In the multiple regression model, gender (P = 0.27), WHR (P = 0.27), sun exposure score (P = 0.006), and winter vs. summer (P = 0.004) explained 10.4% of the variation in 25OHD concentration. Men had a 25OHD concentration 3.71 ng/mL higher than that of women. An increase of 1.0 unit in the sun exposure score resulted in an increase of approximately 0.16 ng/mL on 25OHD concentration. WHR showed an inverse association with the 25OHD concentration. The summer season and sun exposure influenced the 25OHD status in individuals with metabolic syndrome living in a region of Brazil with a high ultraviolet radiation index.

The macroinfauna of two sandy beaches were sampled between winter-2005 and summer-2006 during low tide; one beach was protected (Flamengo beach) located in Guanabara bay, and the other was exposed to waves in the oceanic zone (Grumari beach). The hypothesis that the physical characteristics of the beaches determine the difference in composition and relative abundance of the macroinfauna was tested. Flamengo beach was characterized as dissipative and had comparatively higher t?xon richenes and lower biomass, when compared with Grumari beach that was classsified as reflective. In Flamengo beaches, higher abundance was recordded for Enoploides sp, and Emerita brasiliensis, whereas in Grumari beach Sacocirrus sp and E. brasiliensis were the most abundant taxons. The beaches showed highe dissimilarity in composition and relative abundance of the taxons (91.75%). Sacocirrus sp, Enoploides sp, Dispio uncinata, Scolelepis goodbobyi and E. brasiliensis explained 63.70% of the dissimilarity between the two beaches. In both beaches, we observed extratification in occurence and abundance of the macroinfauna in two seasons. Emerita brasiliensis occurred mainly in Grumary beach in the extrate 1 and Sacocirrus sp in extrate 2, while in Flamengo beach E. brasiliensis and Enoploides sp had the highest abundance in extrate 1 and S. goodbody and D. uncinata in extrate 3. The hypothesis that the macrofauna differs among extrate and beaches was accepted and the differences in composition and relative abundance of the macroinfauna were attributed to morphodynamism, althought other environmental factores can be influencing such differences. / O morfodinamismo, estratifica??o e a sazonalidade s?o os fatores mais importantes na determina??o da composi??o e abund?ncia da macroinfauna em praias arenosas. A macroinfauna de duas praias foi amostrada no inverno/2005 e ver?o/2006 durante a mar? baixa, sendo uma praia protegida (Flamengo) localizada na ba?a de Guanabara, e outra praia exposta localizada na zona oce?nica (Grumari). Foi testada a hip?tese que as caracter?sticas f?sicas das praias determinam diferen?as na composi??o e abund?ncia da macroinfauna. A praia do Flamengo foi caracterizada como dissipativa e apresentou maior riqueza de t?xons, e menor biomassa, quando comparada com a praia de Grumari classificada como refletiva. Na praia do Flamengo as maiores abund?ncias foram registradas para Enoploides sp, e Emerita brasiliensis, enquanto em Grumari foram Sacocirrus sp e E. brasiliensis. As praias apresentaram elevada dissimilaridade na composi??o e abund?ncia relativa dos t?xons (91.75%), Sacocirrus sp, Enoploides sp, Dispio uncinata, Scolelepis goodbobyi e E. brasiliensis explicaram 63.70% das diferen?as entre as praias. Em ambas as praias foram observadas estratifica??es na ocorr?ncia e abund?ncia da macroinfauna nas duas esta??es analisadas. Na praia de Grumari, E. brasiliensis ocorreu principalmente no estrato 1 e Sacocirrus sp no estrato 2, enquanto na praia do Flamengo E. brasiliensis e Enoploides sp apresentaram as maiores abund?ncias no estrato 1 e S. goodbodyi e D. uncinata no estrato 3. A hip?tese da varia??o na composi??o da macroinfauna entre os extratos foi aceita, e as diferen?as observadas na composi??o e abund?ncia da macroinfauna foram atribu?das ao morfodinamismo; no entanto, outros fatores ambientais podem estar relacionados com tais diferen?as.

Definiu-se como ?rea de estudo o bairro M?e Luiza, em Natal, capital do Estado do Rio Grande do Norte. O local foi escolhido por historicamente apresentar diversas condi??es de vulnerabilidade e exposi??o ao risco de desastres. Ap?s caracteriza??o socioambiental do local, foram elaborados dois ?ndices: Vulnerabilidade Social (IVS), com base em 17 vari?veis dispostas em question?rio aplicado ao longo do n?cleo populacional do bairro, sobre malha regular (amostragem sistem?tica), classificado em 5 n?veis de VS a partir de m?dia ponderada; e o ?ndice de Exposi??o aos Movimentos de Massa (IEMM), que teve como base 16 vari?veis que caracterizam condi??es de exposi??o a movimentos de massa no bairro, em n?veis classificados a partir de m?dia ponderada de 1 a 5. A rela??o entre estes dois resultados, especializados em mapa do bairro, produziu o ?ndice de Vulnerabilidade Socioambiental (IVSA) de M?e Luiza, classificado tamb?m em 5 n?veis, a partir de l?gica Boleana de correla??o para sobreposi??o cartogr?fica, com uso de software computacional ArcGIS v.9.3, sendo nomeadas como: Muito Baixa; Baixa; M?dia; Alta; e Muito Alta Vulnerabilidade Socioambiental no bairro. O estudo se baseia em metodologia proposta por Guerra et. al (2009) para o IEMM e Almeida (2010) para o IVS, que foram modificadas e adaptadas para a realidade local, produzindo uma in?dita metodologia aplicada nesta ?rea. Concluiu-se que o bairro tem maior parte de sua ?rea com Alta e Muito Alta Vulnerabilidade socioambiental a desastres, sendo definidas sete (7) ?reas cr?ticas, com Muito Alto IVSA, e perigos associados a movimentos de massa ou alagamento. Ao final elencou-se os principais problemas socioambientais encontrados, como elementos geradores para a proposi??o de medidas mitigadoras e/ou interven??es propostas, referentes a fatores de vulnerabilidade de ordem estruturais: como baixo padr?o construtivo das resid?ncias; drenagem urbana deficiente; im?veis abandonas em via de desabamento; infraestrutura dos acessos e conten??o de talude. E sociais: como falta de educa??o sobre risco socioambiental; renda e escolaridade dos moradores; presen?a de pessoas com dificuldade de locomo??o e/ou portadores de necessidades especiais. Esta realidade evidencia a necessidade de a??es urgentes aplicadas na resolu??o e/ou diminui??o dos problemas apontados, o que ? pauta ao final deste trabalho. / This work has as object the elaboration of social environmental indicator of disaster risk that are present in precarious areas of human occupation, related to intense environmental dynamic from the perspective of the studies about the subject in Geography. The District of M?e Luiza in Natal, capital city of Rio Grande do Norte, was defined as the study area. The place was chosen because it presents ?historically- several vulnerability conditions and exposure to disaster risk. After a local social environmental description, two indexes were elaborated: the Social Vulnerability Index (SVI or IVS in Portuguese), based on 17 (seventeen) variables arranged on a questionnaire addressed to the population nucleus of the district, on regular grid (systematic sampling), classified into 5 (five) levels of SV from the weighted average; and the Physical and Natural Exposure to the Mass Movements Index (EMMI or IEMM in Portuguese) which had 16 (sixteen) variables that feature conditions of exposure to the mass movements in the district with classified levels from the weighted average of 1 (one) to 5 (five). The relationship between these two results, specialized in the district map, produced the Social Environmental Vulnerability Index (SEVI or IVSA in Portuguese) of M?e Luiza, also classified into 5 (five) levels, following the Boolean logic correlation for cartographic overlay with use of computer software ArcGIS v.9.3, being named as: Very Low; low; average; high; and Very High Environmental Vulnerability in District. The study is based on the methodology proposed by Guerra et al (2009) for EMMI and by Almeida (2010) for SVI. They were modified and adapted according to the local reality, producing a new methodology in this study area. It was concluded that the neighborhood has most of its area with High and Very High Socio-environmental vulnerability to disasters, defined seven (7) critical areas, with Very High IVSA, and hazards associated with mass movements or flooding. In the end, the main issues that were found, such as generating elements for proposing mitigation measures and/or the proposed interventions were enumerated, related to structural order of vulnerability factors: how low constructive pattern of households; poor urban drainage; Real Estate forsaken in landslide routes; infrastructure ready access roads and slope containment. And social: as a lack of education about environmental risk; income and education of residents; presence of persons with limited mobility and/or those with special needs. This reality highlights the need for urgent action applied to the resolution and/or reduction of these problems, which is focusing the end of this work.
