Análise dos fatores responsáveis pela alta salinidade do aqüífero fissural da microbacia da Riacho do Feijão - Pedro Avelino/RN

The fissures aquifer northeast semi-arid Brazilian, present high text frequently of leave, with of low a hídric availability. The research has as objective main to analyze the components that inside influence in the salinity of the waterbearing fissures of an evaluation physicist-chemistry of the water, leading in consideration the physical interventions of the environment. One used techniques of interpretation of image of Landsat satellite -1999 and delimitation of the micro basin through the topographical map SUDENE. One identified waters of the NaCl type with Ca++ and Mg++ in secondary concentrations. The analyzed wells (15), had presented an average salinity of 5.147 mg/L of STD and a well only supplies drinking waters with 319 mg/L of STD. The recharge of the aquifer one if carries through for infiltration in the open fracture of ortognaisse it migmatization. The type and directions of the fracture do not control the STD. Relations between salinity and out let do not exist. The quality of the well of low salinity is identical the superficial waters (aquifer dam and alluvial). The studies of the meteoric erosion processes had evidenced that in the transformations of the rock in ground, the Ca++ and Na+ are taken for superficial waters. The treatment of the data chemical showed that the grade of Na+, Ca++, Mg++ and Cl-are controlled for the evaporation process, from only water that would have the qualities of superficial waters or the well of low salinity. Already the HCO3-grade is controlled for the precipitation of the dolomite. The STD of this aquifer one would be consequence of the high tax of evaporation of dams constructed in regions of plain topography. You leave them precipitated in deep argillaceous ones dry dams are led for the aquifer in first rains. The research suggests some recommendations for the use and exploitation of the water salinity in piscicultura, carcinicultura, culture of the grass-salt (Atriplex sp), among others

A representação da mulher e as questões de gênero na toponímia urbana de Caicó-RN

This piece wants to investigate the relations between gender identities and the toponymy in Caicó city. To do so, we will discuss the reason why places are named, the practice of naming places, so as the process of choosing the names of neighborhoods, streets and city public squares. Thereby, we will investigate the space changes in Caicó city since its formation, as a village, until the decade of 1970. This period of time was chosen in order to discuss the toponymic process of the city, besides having noticed that public places and locations in Caico with the feminine nominations only appear from the second half of the 60s decade and in the beginning of the 70s. This way, we preferred to investigate who were the first Caicó women to have their names in the urban space; why women only begin to have homage from the decade of the 60s on; what is the importance and the location of the places with feminine names; and what gender image is there on this homage

Nos tempos do blackout: cena musical, práticas urbanas e a ressignificação da Rua Chile, Natal-RN

This study aims to analyze the process of resignification of Chile Street, in Natal, from the development of a music scene in the late 1990s. Chile Street, as part of the Historic Centre of Natal, had its images constructed from the discursive practices and everyday life of its regular visitors, leading to a series of symbolic and imaging transformations throughout the twentieth century. Initially transformed into glamorous space as a result of urban actions of the new republic of Albuquerque Maranhão, in the early twentieth century, Ribeira and Chile Street, specifically, came to be seen as bohemian area, during the war time"; followed by a marginal phase, it was eventually transformed into the main rocker area of Natal, with the development of a musical scene in the second half of the 1990s. This music scene, its practices, economic interests, cultural events and identity ties created among their practitioners made Chile Street, "in the time of Blackout night club", an "alternative" space. As the historic centers, inserted in the logic of postmodern city marketing, both spaces are dynamic in their practices, as in their images, Chile Street also suffered changes in its meanings and symbols, around the year 2000 when the alternative-underground space became a pop space, where people from various parts of the city began attending its events and places, transforming it into a point of very heterogeneous sociability

Caracterização estatística de processos sísmicos via Distribuição Generalizada de Pareto. Estudo de caso: João Câmara-RN

The work is to make a brief discussion of methods to estimate the parameters of the Generalized Pareto distribution (GPD). Being addressed the following techniques: Moments (moments), Maximum Likelihood (MLE), Biased Probability Weighted Moments (PWMB), Unbiased Probability Weighted Moments (PWMU), Mean Power Density Divergence (MDPD), Median (MED), Pickands (PICKANDS), Maximum Penalized Likelihood (MPLE), Maximum Goodness-of-fit (MGF) and the Maximum Entropy (POME) technique, the focus of this manuscript. By way of illustration adjustments were made for the Generalized Pareto distribution, for a sequence of earthquakes intraplacas which occurred in the city of João Câmara in the northeastern region of Brazil, which was monitored continuously for two years (1987 and 1988). It was found that the MLE and POME were the most efficient methods, giving them basically mean squared errors. Based on the threshold of 1.5 degrees was estimated the seismic risk for the city, and estimated the level of return to earthquakes of intensity 1.5°, 2.0°, 2.5°, 3.0° and the most intense earthquake never registered in the city, which occurred in November 1986 with magnitude of about 5.2º

Fatores associados à condição de saúde bucal de pacientes internados em hospitais públicos do município de Natal-RN

The hospitalization is an event that can attack any person, independent of gender, race, social and economical condition. Last year, the prevalence of hospitalization was 8.1 for 100 inhabitants and the average time of hospitalization was 8.5 days for each patient one in Natal city. Therefore, an important point is whether the attention to the patients during the permanence in these health establishments incorporates the health integral model suggested by the principles proposed by the National Health System in Brazil (SUS), with actions of promotion and protection by different kinds of professionals, beside those called convalescence. Then, the aim of this study was to evaluate the patient s oral health conditions hosted in public hospitals of the Natal city, looking for to establish its relationship with several risk factors by two dimensions: the characteristics of the hospitalization and the patient s general and economical conditions. We accomplished a cross-sectional study with 205 patients distributed among the hospitals Onofre Lopes, Giselda Trigueiro and Monsenhor Walfredo Gurgel, looking for to know the socio-demographic characteristics, the food habits and of oral hygiene and the conditions of oral health, through the Visible Plaque Index and Gingival Bleeding Index. We observed that the conditions of the patient s oral health interned at public hospitals of reference of the municipal district of Natal is bad, existing accumulation of dental plaque and, consequently, a great number of patients with gingival bleeding. However, the time of hospitalization and its reason, the type of medicine used in this time and the toothbrush frequency were not configured as risk factors for this oral health condition

Prevalência e determinantes de oclusopatias nas dentições decídua, mista e permanente na cidade do Natal/RN

This work is intended to bring a contribuition to the verification of the prevalance of malocclusion in the deciduous, permanent and mixed dentition in the student population in the city of Natal, Brazil. In this purpose, a sectional study of infantiles aging 5, 8 and 12 years old was carried out. The average prevalance of malocclusions in the group as a whole was 76,5%. Considering the different dentitions separately, the study showed malocclusion prevalence as follows: Deciduous Dentition 75,5%; Mixed Dentition 84% and Permanent Dentition 70,5%. The most common malocclusion cases found in the deciduous dentition were openbite (20.6%); overbite (16.6%) and maxillary overjet (14,7). Mixed Dentition: the most commonly found occlusional malfunctions in this dentitional phase were maxillary overjet (33,8%); crowding (28,3%), and mandillary discrepancy (19,9%). In the univaried analysis, he application of the Chi square test of independence, (significance 5%), has indicated a meaningful association of the variables social class (p=0,019), primata space (p = 0,036), habits (p= 0,002) and time-and-habit (P=0,03). The same test on the permanent dentition group revealed a significant association for the independent variables, as follows: Social class (p=O,OOO), School (p=O,OOI), Income (p=O,OOO), housing standard (p=0,001), facial pattem (p=0,004), caries record (p=0,031). No significant association was found in the mixed dentition. The Logistic Regression analysis on the deciduous dentition has shown that income, ethnicity, habit and canine relationship constitute factors of risk regardless of the other variables. As for the permanent dentition, only Facial Pattem was pointed as a factor of risk for the formation of malocclusion

Caracterização do processo de trabalho do cirurgiãodentista na estratégia de saúde da família do município de Parnamirim-RN

Family Health Strategy (FHS), founded in 1994 has appeared to play a strategic role in the SUS construction and consolidation. It has reaffirmed its Principles and Guidelines and has elected family as core of attention. The principle that has guided the work concerns the quality of the relationship between professional and family. Thus, the FHS has the family as a subject of health-disease process, and relations with its own characteristics and can be partners in building their health and improvement of quality of life of its members and the entire community. This study aims to characterize the surgeon-dentist (SD) working process in the family health strategy, from the knowledge of the SD integration with other team members; organization of services; development of shares, changes perceived by SDs, as well as knowing the surgeon-dentist profile who is part of this strategy. The collecting tool used was a semi-structured questionnaire, in which participated 30 professionals. As for profile, most professionals were women, completed the graduation in public university and did not have any training to work by joining the FHS. Almost all have other public or private working ties. They often carry out activities with students, and occasionally do home visits. In relation to team work, in activities such as home visits, school health, community activities, among others, they sometimes seek the cooperation of other members. The way of accessing for users in the most part has occurred through the schedule. The most frequently activities made to the Centro Especialidades Odontológicas (CEO), are in Endodontics and Prosthesis. The majority of them participate in team meetings, but they do not have frequency set to happen. As for the planning and programming of activities to be conducted, most said that individually develops them. Concerning the performance of their duties, most reported being satisfied, but that improvements could happen. Besides, they reported improvements in dental care following the inclusion of SD in the FHS in various aspects, such as access, organization, humanization, care and oral disease prevention. The professionals had poor integration with other team members, in addition to have a profile to more individualistic work, a fact seized by way of development and planning of actions. They work the actions in individual and curative way, in detriment promotion and collective ones. They work humanization, definition of territory and adscript population. Thus, it is concluded that the working process developed by SDs, includes the part which is advocated by FHS. This points out to a greater undertaking of this process aiming to detect the weakness met in order to reach the potential that the FHS represents in organization of basic attention

Assistência odontológica diferenciada para crianças de 0 a 3 anos: avaliação de impacto no Serviço Público Municipal em Natal-RN

In Brazil, 0-5 years old children just have an oral health care system since 1990 s. Innumerable experiences of implantation of the attendance to the babies in the cities had appeared throughout the years, but it hasn´t been evaluated the comparative effect between children displayed and not displayed to the program. In this regard, the main of this research was describe the Early Childhood Oral Health Care in public health service in Natal, Rio Grande do Norte, Brazil and evaluate the impact of this specific oral health care for babies by comparison of indicators between exposed and non-exposed children. It was created an experimental group, formed by children covered by program which was paired, based on sex, age and socioeconomic status, with a control group, formed by uncovered children. After filling ethical application, the parents of children were questioned about some risk factors to dental caries and, in sequence, it was accomplish an oral examination in the child. It was verified the Visible Plaque Index (VPI), Gingival Bleeding Index (GBI), dmf-s and verification of caries activity. The sample was 40 children in each group. The results showed, for VPI, a difference of 7 percentile points for the experimental group, however this difference had no statistical significance, obtained by Student s t test (p=0.314). In relation to GBI, the control group showed a low mean (0.8%) comparing with experimental group (2.77%) and this difference was statistically significant (p=0.003). The results for dmf-s and evaluation of caries activity showed no statistical difference between groups. Among the probable reasons for absence of impact of intervention, could be included: (a) the practice model was the same in two groups, or the difference was very weak and (b) the oral health care has intrinsic limitations for to impact on oral health in low income populations

Satisfação dos usuários e qualidade dos tratamentos protéticos realizados nos centros de especialidades odontológicas da grande Natal RN

Aim: To evaluate user satisfaction and quality of prosthetic treatments performed in specialized dental clinics (CEOs) of Natal Metropolitan Region - RN. Methods: Cross-sectional study with subjects who underwent prosthetic CEOs in the cities of Natal, Macaíba, Parnamirim and Sao Goncalo do Amarante in the period 2007 to 2009. Data collection was performed by questionnaire, clinical examination of the oral cavity and examination of fabricated denture. This analysis involved the following aspects: retention, stability, aesthetics and prosthesis fixation. The variables are presented by means of absolute numbers and proportions. The determination of the association between the independent and dependent variables was conducted by the association of Chi-square test and Fisher exact test. Results: A total of 149 users, totaling 233 conventional dentures (148 upper and 85 lower). Most patients (56.4%) were rehabilitated with conventional complete dentures. The technical quality of the denture was regarded as satisfactory in the majority (52.7%), whereas the inferior dentures were rated as unsatisfactory in 90.5% of cases. Satisfaction with the prosthesis was 69.1% (N = 103). The average time to begin treatment was 3 months to receive while the prosthesis was 4 months old. The presence of injury from the upper prosthesis occurred in 21.5% of cases (N = 32), candidiasis being the most frequent (N = 18). The technical quality of the upper prosthesis (p=0,041), as well as retention (p=0,002) and stability (p<0,001) were significantly associated with user satisfaction. Conclusions: The specialized Dental clinics has been fulfilling its role of providing treatment of intermediate complexity for low-income population with the majority of satisfield patients, even when their dentures have problems of technical quality

Avaliacão da satisfação do usuário e da qualidade dos tratamentos endodônticos em Centros de Especialidades Odontológicas da Grande Natal-RN

Objective: To evaluate the degree of users satisfaction and technical quality of endodontic treatment in specialized dental clinics (CEO) of Grande Natal / RN between 2006 and 2008. Methodology: evaluated 282 endodontically treated teeth in CEOs through clinical and radiographic examinations. A questionnaire about the clinical condition of the tooth, evaluation of care and satisfaction with treatment was applied. Data on pre-and trans-operative were noted by the patient's clinical record. Endodontically treated teeth were examined by a specialist in endodontics, which compared with previous radiographs and current ones. The collected datas were presented descriptively by absolute numbers, percentages, averages. To determine the association between the independent and dependent variables was carried out through the bivariate association test Chi-square and Fisher exact test. Results: 79.8% presented with radiographic normal and 84.4% without pain symptoms. 8.2% of the teeth were fractured and 3.2% extracted. The persistence of the periapical lesion was associated with initial periapical status (p <0.05). 91.5% of patients are satisfied with the outcome of treatment. Such satisfaction is associated with absence of pain and an adequate esthetic tooth position (p <0.05). Conclusion: endodontic treatment in specialized dental clinics have an adequate technical quality, resulting in the success of endodontic therapy performed in these centers and that users are satisfied with the treatment

Atividades preventivas realizadas pelos cirurgiões-dentistas do PSF de Natal-RN

Family Health Program (FHP) presents itself as a restructured model on basic cares besides having prevention practices and promotion in health as essential parts. According to that, the purpose of this study is to perceive which prevention practices in oral health are accomplished by the dentists from the FHP of Natal-RN as well as the way they have been developed, the knowledge basis to execute the procedure and the use of evaluation instruments by the dentists and by the Oral Health Co-Ordinator. A list of dentists participating on the FHP of Natal in March, 2006 (n= 91) was obtained so it was possible to formulate a structured interview. After excluding those with less than six months attending to the program, and considering the loss, eighty dentists got to be interviewed. It had questions about individual and group preventive procedures, sources of basement to develop the activities and to verify the impact and evaluation instruments. Besides that, an interview was made with the Oral Health Co-Ordinator about the evaluating process and the existence of a protocol as well as about document analysis in the Ambulatory Informations System Unique Health System (AIS-UHS), Information of Basic Care System and Pact of Recorder. The main individual activities consist on Oral Hygiene Orientation (87,5%) and Fluoridization (95%). Group activities remain at scholar groups acts(91,25%) being fluoridization done by 91,25% and educative activities by 86,25% mainly through speeches (61,25%).Orientations about oral cancer were detached on the aged group (39,96%)and hypertensive and diabetic group (19,51%), as well as integration with the health team was respectively 21,93% and 39,02%. Speeches and talk rounds are the main activities for aged, hypertensive and diabetics, and are also expressive to pregnant women. For pregnant women and babies group predominate hygiene and diet orientation. About the evaluation instruments 73,75% of the dentists do not consider their existence, despite 73,75% consider that actions have impact specially due to a increase of hygiene and decrease of caries index on the children. The main sources of basement are clinical experience (42,5%) and preparative courses (33,75%), only 7,5% mentioned population need and local reality. The Oral Health Co-Ordinator related the Attention Pact Recorder and records from the AIS - UHS as evaluation source but also detached the lack of epidemiologic surveying. She mentioned the increase of supervised brushing as a positive result and detached the hardness of the professional to act inside the family and as a team. The AIS-UHS records showed that fluoridization is more used individually and the supervised brushing is predominant as a group action, besides that educative activities at the Health Establishment predominate due to actions at the community. Facing the results, it was verified the act in different groups, special attention given to scholars, as well as focus the activities on caries giving less emphasis to other oral problems. Despite that, there was no epidemiologic instruments or data of the local reality to guide the actions and to be part of the planning and evaluation process
