Aspectos ambientais e sociais envolvidos na transmissão da L. chagasi no município de Parnamirim/RN

Visceral leishmaniasis hás adapted in the past 20 years to periurban and urban areas, and in Natal, Rio Grande do Norte, it became endemic. Thid study aimed to evaluate the environmental and social aspectsof Leishmania chagasi infection and its epidemiologic transmission chain in an urban, periurban and rural area of Parnamirim-RN. A study with three sections was conducted: Section 1: Sectional study of the human and canine infection by L. chagasi and its environmental and social determinants. Section 2: Observational longitudinal cohort to evaluate the dynamics of the canine infection. Section 3: Longitudinal study to evaluate the behavior of Lu. Longipalpis vector and the seasonal factors related to its dynamics. To include in the study the hauses were randomly selected and georreferenciated. Montenegro skin test was done in the human population and blood samples were collected for anti-Leishmania antibody detection. The canine population was examinated for L. chagasi infection by RIFI, ELISA and ELISA for rK39. An entomologic surveillance was monthly done with CDC light trapsin 10 houses of each locality. Quantitative and qualitative analyses was done using STATISC 6.0. Probality and prediction maps were done using ArcGis 9.0 model. In the human population L. chagasi infection was associated with the area of the hause, age, sex, population densyti, vegetation, kind of the floor of thr hause, water and resides destiny. In the canine population L. chagasi infection was associated with the breed, size, time of living in the hause, presence of dogs in the neighborhood, presence of horses and donkeys in the neighborhood, vegetation, kind of the floor and walls of the hause. The human infection was associated with canine infction only when analyzed taking into account the locality. In the prospective study, serum conversion and antibody lost observed in 30,8% and 22% of the animals examined, respectively. The human infection rate by L. chagasi was 24,6%, by the presence of anti-Leishmania antibody and 38,6% by the Montenegro skin test. The canine infection rate 32,5% by the presence of anti-Leishmania antibody. The vector Lu longipalpis showed an atypical behavior. These results indicate that environmental and social factors are important variables associated with L. chagasi infection in humans and canines, with punctual association of thr last two. Control measures of the infection on the studied points are necessary, in the aim to reduce the endemic focus of the disease in the study area. This research was carried out in a multidisciplinary involving the categories of: doctor, biologist, veterinarian, statistical, pharmaceutical and biochemical

Environmental enrichment reduces aggression of pearl cichlid, Geophagus brasiliensis, during resident-intruder interactions

Em lutas entre peixes residentes e intrusos, residentes geralmente vencem, provavelmente porque valorizam o território mais do que os intrusos. Nós aventamos a hipótese de que ambientes enriquecidos aumentam o valor da área em disputa, levando os residentes a defenderem mais violentamente ambientes enriquecidos de recursos do que ambientes empobrecidos, pois possuiriam mais motivação para mantê-lo. No entanto, no presente estudo, ao testarmos as interações entre intrusos e residentes em acarás, Geophagus brasiliensis, observamos que o enriquecimento ambiental reduz a agressividade e pode levar a cohabitação entre os peixes, sem luta. Adicionalmente, em nossos experimentos, o efeito da residência prévia ocorreu independente da condição de enriquecimento. A diminuição das interações entre os peixes e, consequentemente, a diminuição do nível de agressividade é aqui atribuída aos efeitos da diminuição da visibilidade entre os peixes devido ao aumento de complexidade do ambiente.

Modos de ser e modos de viver : a trajetória dos estrangeiros em Natal/RN

This work aims to understand the trajectory of immigrants living in Natal / RN, between the years 1990 and 2009, their motivations for this change, their sociability relations, as well as the impact of this group in Natal and specifically, in the district of Ponta Negra, where most of them established their residences or work. Considering that the historical, political, economical and social environment where these immigrants are inserted, are different from that experienced by former immigrants who came to Brazil in the late nineteenth and early twentieth centuries, a period of mass migration, it was revealed that immigration studied in contemporary Natal constitutes a new configuration (Elias, 1994). This new configuration is represented by several characteristics that distinguish this contemporary immigration, as: the relationship established by these foreigners, both with their country of origin and the destination, the formation of social networks that offer support to newcomers and those already installed, the relations of sociability with locals and a new relationship of belonging with the space, since the possibility of coming and going from one country to the other, allows a (re)production of their original ?? social and economic life in the new space. The research methodology was based on the analysis of narrative interviews, in light of the theory of Schütze (1977) in order to understand the faces of this immigration. As theoretical support for the data analysis the theories of authors such as Norbert Elias, presentedin his work about the established and outsiders, Pierre Bourdieu, and his concept of habitus, distinction and style of life, Georg Simmel, and his study of life in the metropolis, his analysis of the foreigner and his theory of sociability, among others. This study attempted to give visibility to foreigners living in Natal, who experience the dynamics of the district of Ponta Negra and reconstruct their daily relations of sociability in this space. In fact, the presence of foreigners in this urban context allows for the construction of new configurations, both in terms of the physical space of the neighborhood, which has been modified by the touristification process and the real estate market, which is molded to meet this demand, but also in their social sphere, with regard to the relations established between foreign residents and locals. In seeking to characterize these migratory experiences it could be understood that the trajectories of each foreigner is part of a broader social structure, which cannot be evaluated neither disconnected from the contexts in which they operate, nor under a single point of view

Indústria cultural e forró eletrônico no Rio Grande do Norte

The present study aimed to understand how and to what extent the electronic forró, currently hegemonic in the music market in the state of Rio Grande do Norte, establishes and maintains relations of domination in the social contexts in which it is produced, transmitted and received. Based, in significant form-content, on the writings of the first generation of theorists of the so-called Frankfurt School (Critical Theory), particularly with Theodor W. Adorno, and systematically using the contributions of the Cultural Studies (from the Centre for Contemporary Cultural Studies of Birmingham) and of the sociology of Pierre Bourdieu, this study aimed to perform, in the fertile intersection of these references, a critical possibility of interpretation of the electronic forró predominantly spread in the state of Rio Grande do Norte. To this end, aiming at a better apprehension of the so-called capital circuits/culture circuits , this study resulted from a qualitative investment of research, based on structured interviews with musicians, entrepreneurs of the sector and music consumers, as well as on the analysis of the themes contained in the official discography of the electronic forró band called Garota Safada (Shameless Girl). As a general empirical conclusion, it was possible to infer that far from the significant presence of domination or mere prevalence of oppositions, there is a relational pluralism of forms of domination and ways of resistances present in the production and consumption of electronic forró, regardless of gender, age, income, education or place of residence. However, the artifices of the cultural industry has been shown to be efficient: from large-scale businessmen to small producers enabled by the so-called open markets . The currentness of the concept of cultural industry is based on the idea that its products are offered systematically (the systematic insistence of everything to everyone) and on the notion that its production primarily meets the administrative criteria of control over the effects on the receiver (capacity of prescription of desires). Thus, the Adornian reflection on the pseudo-individualization leads to the inference that even in some of the most apparent ways of negotiation and/or refusal regarding the consumption of forró, certain behaviors of the cultural industry still prevail both in the very (re)interpretation of the forró and in the choice of other music genres also standardized, rationalized and massified. Therefore, despite the absence of cause-effect relation and the recognition of the popular capacity of re-elaboration and contestation of the media consumption, some world views prevailing in relation to the electronic forró establish or, at least, support some hegemonic ideologies, especially those concerning the life style, consumption and genre relations (fun by all means). Therefore, due the massification of certain songs, some ways of dissemination of values, beliefs and feelings are potentially experienced from the electronic forró. So, it is presumable that in the current advance of the process of semiformation (Halbbildung), the habitus of a part of the youth from the state of Rio Grande do Norte reinforces and is reinforced by the centrality of the trinomial fun, love and sex present in the songs, emphasized in some constructive practices of sense and in certain flows of social significance

Efeitos de um programa de intervenção precoce baseado no modelo mais que palavras - HANEN, para crianças menores de três anos com risco de autismo

In the last decades, studies on early intervention involving children with autism have suggested that there is no single intervention model capable of addressing the needs of all individuals in the spectrum. The role of parents as active intervention agents is, however, highly recommended. The More Than Words-HANEN Program has been specifically created for parents of children, under five years of age, who are in the autism spectrum. This intervention aims at improving the social competence and language comprehension of the child, as well as their parents empowerment. Until now only three studies have been performed in order to evaluate the effectiveness of the HMTW program. The purpose of this investigation is to evaluate the effects of an early intervention program inspired on HMTW model on the level of caregiver responsiveness and child communication skills. The present study adds to the existing research literature on family-centered early intervention that uses a developmental paradigm. A two year boy in risk for autism, his mother and nanny took part in this investigation, which was carried out in the child´s home in Mossoró, Rio Grande do Norte. The caretakers were given one fifty-two hours of training, divided into thirteen weekly meetings. A quasi-experimental A-B-C design (baselineintervention- follow-up) showed improvement in the caretakers level of responsiveness and meaningful social-communicative gains in the child´s response

Qualidade de vida na perspectiva de idosos institucionalizados no Município de Natal - RN

A descriptive and exploratory Study, quantitative in nature, with the aim to assess the Quality of Life (QL) of the elderly leaving in a Long Residence Institution (LRI) according to their own perception. It was conducted in six Public Institutions of Long Residence for Seniors, in the municipality of Natal - RN, in the period of July to August 2007. The data was collected using two structured interview forms: the first, containing questions about socio-demographic aspects and the second - the WHOQUOL-OLD, prepared by the World Health Organization to assess elderly s quality of life. The reference population was 266 old persons, and a random sample, of 43, being 28 women and 15 men, who account for 30%. The results indicated there is a predominance of older women (65.1%) and the average age is 76.6 years; the predominant religion is the Catholic - 44.2% and, 32.6% are unmarried without children. As for schooling and precedence, 41.9% are illiterate and 67.4% come from the rural area. The time of residency in the institution goes between 1 to 5 years for 69.8% of the elderly, 37.2% of them residing in the institution for not having another option. Most elderly informed using medicines. 51.3% said they are taking anti-hypertensive. As for the other aspects of QL: sensory aspects, autonomy, past, present and future activities, social participation, death and dying and intimacy, the WHOQOL-OLD, showed an average total score of 52.9% (scale of 0 to 100), with a tendency to neutrality, denoting that the elderly, in this study, evaluated their QL as neither satisfactory or unsatisfactory. Of all the facets of the instrument of QL, the sensory facet secured the highest average scores (68,1%), showing that the elderly are "happy" in the situation in which they find themselves, not showing significant disabilities. The facet of autonomy, which refers to the independence and the ability to make decisions on their own life, received the lowest average scores (40.7%), showing the dissatisfaction of the elderly on this aspect. The evaluation of the elderly on other facets were: social participation (48.2%); activities past, present and future (44.6%) and intimacy (50.6%), all perceived as neither unsatisfactory or satisfactory. On the item death and dying, the elderly people declared themselves satisfied, with average score of 65.5%. The analysis of the reliability of the WHOQOL-OLD by the Cronbach Alpha showed 0.57, considering the 24 items that cover the instrument, showing regular internal reliability of the instrument, in our reality. The result is probably due to differences between the regions south and east and the broader sociocultural diversity. We believe that the elderly in this study, tended to realize their QL as neutral, considering it as neither unsatisfactory or satisfactory, result likely related to the resignation with the destine, characterized, at the time, by the finitude of life, feeling very common among elderly, or perhaps, even for an accommodation, often accompanied by discouragement, present in the daily life of many of them

Trajetória do hospital dia Dr. Elger nunes: um recorte histórico da psiquiatria e saúde mental no Rio Grande do Norte

In Brazil, the mental health network proposed by the Psychiatric Reform inserts the intermediate and replacement services in the pursuit of alignment or resocialization of patients with mental and behavioral disorder in the community. Was adopted, among other services, the Center for Psychosocial Care, Home Therapy, Sheltered Home, Day Hospital and psychiatric beds in general hospital. In this context, the State of Rio Grande do Norte implanted the Day Hospital Dr. Elger Nunes (HDEN) in Natal / RN in 1996, linked to State Department of Public Health. At HDEN happened a multi and interdisciplinary therapeutic work, besides being the scene of disciplinary practices, and extension projects for graduate courses in Higher Education Institutions in the city. However, with the process of decentralization of local services, the hospital was terminated by an administrative state act in 2006, leaving damage to the activities provided to users, disciplinary practices and extension activities. From this breakdown, the objective was to narrate the trajectory of HDEN through a multidisciplinary team of professionals and teachers who used it as a field of disciplinary practices. It is characterized as a documental and qualitative, backed in the technique of thematic oral history, following the phases: authorization of the interviewee, interview recording, transcription, textualization and transcreation of the material obtained. We used documents, ordinances, general reports of activities, among others, plus interviews to fifteen employees who used this service, being thirteen part of the multidisciplinary team of professionals and two graduation professors of health care area, nursing and medicine. The stories collected were organized according to the technique chosen, respecting its steps. In preparing the body subjected to ALCESTE computer program, priority was given to the vital tone for the formation of categories and classes elected by the program, structured in three thematic areas. In the first axis, called Trajectory of HDEN, were recalled the beginning of its activities, the steps of that time, their activities, and its actors - users, families, professionals, and teaching practices. The second axis has dealt with the process of extinction of HDEN, rescuing the feelings of employees, the main reasons given at the time and immediate postextinction scenario. And the third axis revealed in an articulated form the situation of mental health in Natal / RN, listing to the challenges and prospects for the psychosocial care, starting from the trajectory of HDEN with emphasis on activities. Moreover, the trajectory of HDEN provides recognition of the historical basis outlined in the constitution of the network of substitute services present in the current scenario of psychosocial care in the city of Natal and in RN.

As ações de controle da tuberculose na atenção primária à saúde: a visão do doente

Tuberculosis is a disease of great impact on the world context today. In Brazil, the disease management was directed to the Primary Health Care, due to the determination of the Ministry of Health to decentralize health actions for primary care. Thus, since the actions of diagnosis, treatment and control of the disease should happen in this context, however, there are still many barriers that may hinder the realization of these determinations. This study aims to analyze the development of tuberculosis control activities conducted in the services of primary health care from the patient's vision. This is a descriptive, cross-sectional and quantitative study. The population consists of 517 tuberculosis patients treated in units of Primary Health Care in the city of Natal-RN; the sample consists of 93 TB patients. The collect instrument is structured, based in The Primary Care Assessment Tool (PCAT), validated in Brazil and adapted to assess attention to TB in Brazil, with modifications. This instrument was divided into blocks: the first one describes the socio-demographic information of patients with TB and the second one describes the health services working in control, diagnosis and treatment of TB, and includes issues related to the dimensions of primary care: access, bond, services, coordination of care, guidance to the community and family focus. For quantitative analysis, were built indicators for each item of the instrument. The response patterns are followed according to the Likert scale, which was assigned a value between one and five meant that the degree of preference relation (or agreement) of the statements. Values between 1 and 3 were considered unsatisfactory for the indicator, between 3 and less than 4, regular, and between 4 and 5, satisfactory. The results indicate that 62.37% of patients are male, 27.96% aged 41 to 50 years old, and 34.41% unemployed, with low education and low family income. It was found that the reference hospital services are the front door to the patient (59.14%), and are also the local diagnosis of the disease (72.04%). On access, the conditions satisfactory found are: the number of times the patients need to pick up the health care issue, the marking and the facility to get a consultancy in the HS, assistance provided without harm to the individual's attendance labor and facilities related to the proximity between the residence and services; were considered unsatisfactory conditions related to travel to the HS, and on hours and days of operation of services. As for the cast of services were satisfactory and regular actions related to the request for examination to become viable in the first HS, the availability of pot to perform smear and medicines for the treatment, as well as consultations control and receiving information about the disease and the treatment performed; it is considered unsatisfactory the performance of the home care for patients with TB by the HS that acts as a front door, for implementation of the Directly Observed Treatment (DOT), home visits during treatment, the provision of transportation allowance to the patient and the existence of groups for TB patients. Regarding the coordination of care, resulted in regular the action of referring the patient to other HS to obtain examinations, and as unsatisfactory referral to obtain medications. The relationship bond between patient and health team were considered satisfactory in the majority or regular. As for the family and community focus, is satisfactory only the indicator relating to questions from professionals to the patient about the existence of respiratory symptoms in the family. It is considered that there is need for greater commitment from government entities to the incentives required to TB control, as well as the availability of necessary inputs and training of human resources working in the PHC in the ongoing quest to strengthen primary care, as a place of broader host needs to contact the user with the actions and health professionals. It is recommended the adoption of management mechanisms possible to expand the capacity of the health PHC, promoting the service delivery to the user and ensuring attention to population health.

Trauma em idosos atendidos pelo serviço pré-hospitalar móvel

O The aim of this study was to characterize the occurrence of trauma in the elderly population served by the mobile pre-hospital service, in Natal, Rio Grande do Norte. This is a descriptive, transversal and quantitative approach and whose population consisted of 2,080 trauma victims. The sample, of systematic random type, consisted of 400 elderly people, aged from 60 years old, assisted by the Office of Mobile Emergency in Natal / RN, between January 2011 and December 2012. Data collection began after consent and assent of the institution of a Research Ethics Committee under No. 309 505. It was proceeded to documentary retrospective analysis of records of this service through a form of self-development, validated by expert judges considered reliable (α> 0.75) and valid (CVI = 0.97) in their clarity and relevance. Data were tabulated by the Statistical Package for Social Sciences, version 20.0. The results show that older victims have an average age of 74.19 years old, with a prevalence of female involvement by chronic diseases, especially hypertension, average usage of 2.2 routine medications with vital signs within normal limits. The trauma prevailed during the daytime, in the residence of the victims, north of the city and on weekends. Among the mechanisms of trauma were falls, traffic accidents and physical aggression, whose most common type was brain-cerebral trauma and the main consequences were suture wounds and closed fractures. Basic Support Units were as more driven to pre-hospital care (87.8%) and the main destination place consisted of a referral hospital for emergency of the state (57.5%). Among the most commonly performed procedures by nursing staff immobilization with rigid board and neck collar and the peripheral venipuncture, and the main component used for volume replacement to saline were highlighted. There was a significant relationship between the deaths and the mechanism of injury, mechanism of injury and procedures, except medication administration procedures carried out, except immobilization and unit for service. It is highlighted the prevalence of trauma in the elderly, poor follow-up Pre-Hospital Trauma Life Support protocol and the paucity of records and nursing procedures performed. There is need for a protocol of care specific to elderly trauma victims and education strategies for the prevention of such events

Responsabilidade social e competitividade :um estudo sobre a influência de práticas sociais na decisão de escolha de um destino turístico

The work objective was to investigate the influence of social practices social in the choise decision of a tourist destination. For in such a way, a survey with the aid of a questionnaire, was used as being the research instrument. The study used a simple random sample without replacement, due to elements of the population had a equal probability different of zero, to be selected for forming part of the sample. The used collection method of data was personal interview. The data was collected at Augusto Severo International Airport at the moment in which tourists were embarking in return to the residence place or another tourist destination. For determination of sample size, it was considered the tourist who had visited Natal in November and December, 2004, supplied by the Secretariat of Tourism in the RN. The sample for the research was of 403 people. Results showed that the interviewed express the existence of high level of competitiveness in the tourism industry. It was observed that 42.5% of the interviewed believes to exist a very aggressive competition, and 47.5% believed that the competition is aggressive in the tourism industry. 10.4% of the interviewed expressed much interest in knowing about social practices in the tourism industry and 2.8% had not presented any interest in knowing about social practices in the tourism industry. For the interviewed, the travel agency image is a significant item in the choice for a tourist package, because of 35.6% believed that this factor is very important in the choice. 5% of the interviewed only find that little important or that sometimes the travel agency image can be seen as s decisive factor in the tourist package choice

Análise do desempenho térmico de um sistema de aquecimento solar utilizando coletor com superfície absorvedora em chapas de PVC

It s presented a solar collector to be used in a system for heating bath water, whose main characteristic is its low cost. The collector consists of five plates of PVC with 10 mm thick, 200 mm in width and 1400mm in length, with an area equal to 1.4 square meters. The plates were connected in parallel to the ends of PVC tubes of  40 mm and 32 mm. The plates were coated on one side with aluminum sheets of soft drinks and beers cans open. The system worked on a thermosiphon and was tested in two configurations: the plates uncoated and coated with aluminum material, to determine the influence of material on the efficiency of the collector. For both configurations was used EPS plates below the surface to minimize heat losses from the botton. The thermal reservoir of the heating system is, also, alternative and low cost, since it was constructed from a polyethylene tank for storing water, with volume of 150 end 200 liters. It will be presented the thermal efficiency, heat loss, water temperature of the thermal reservoir at the end of the process and simulation of baths for a house with four residents. The will be demonstrated thermal, economic and material viability of the proposed collector, whose main innovation is the use of recyclables materials, cans of beer and soft drinks, to increase the temperature of the absorber plate.
