Instituições, agricultura familiar e crédito rural: avaliação de resultados do Pronaf B nos territórios rurais do Rio Grande do Norte

Broadly anchored on Institutionalist literature this dissertation seeks to answer: Why rural credit granted to farming families in Rio Grande do Norte, Pronaf group B, has shown positive results in some territories while in others the same results are insatisfactory? Considering formal rules are the same, then why such results are so distinguished? This research supports the fact that these results are a direct consequence of the quality of institutions defined as longstanding social rules established and built in social interactions. For institutions one understands; organizational structures, formal and non-formal rules, social trust, thinking behaviors and its evolution as well as routines. Using Pronaf Rural Credit as a background this study measures and compares results obtained in the rural areas of Seridó, Sertão do Apodi, Mato Grande, Assú-Mossoró, Trairi, Potengi and Alto Oeste. The dimensions of measurement considered were: economics, social and guarantee of transparency. The study considers a sample of 402 Group B farming families. It also elaborates a socio-economic profile of these families in the considered areas and underlines the main causes for defaulted loans, difficulties to improve family income and results of access to Pronaf B credit line, as well as it proposes solutions to surpass obstacles to improve the efficiency of this credit line

Programa Nacional de Incentivo à Leitura - PROLER: avaliação da implementação pelo Comitê Potiguar

The National Reading Incentive Program (PROLER) is a national initiative to promote and encourage reading throughout the country, linked to the National Library Foundation (FBN) of the Ministry of Culture (MinC). This research aims to assess the PROLER’s implementation process in the state of Rio Grande do Norte, from the actions of their local committee. The framework is based on contextualize the policies that seek to encourage the book and reading, as well as the processes of implementation and evaluation of public policies. The research is understood as a qualitative descriptive-exploratory study, comprising a single case study. Makes use of semi-structured interview as a tool for data collection, which was attended by 8 members of Potiguar Committee as respondents. The techniques of bibliographical and documentary analysis were used for the analysis and discussion of data obtained from surveys and documents on PROLER; as to the content of the interviews, the technique used was the analysis of conversations. As for the results, the existence of four barriers to program implementation in the state that are worth mentioning is observed: a) the political-administrative discontinuity; b) the limited resources and few partnerships; c) the management of school libraries and absence from the post of librarian in the state and; d) the absence of a process or assessment tool able to evaluate the results or the impacts of actions taken by the Potiguar Committee. It was noticed that these limiting four come PROLER making the implementation of the Rio Grande do Norte a process that, although complying with the national regulations of teacher training and follow school libraries and their needs, not flawed to develop assessments that can measure program impacts, making the feedback process of ineffective policy. Another observation of this study is seen in the fact that the Committee did not get enough to supply their shares resources, as well as not being able to articulate new partnerships, thus contributing negatively to the scope of the program form and, consequently, for the effectiveness of their actions. Has even mentioning the fact that the Committee do nothing regarding the mismanagement of the libraries that are in their care, ie, do not use the power of coercion as guaranteed by the National Policy on Reading and federal laws that treat the school library, and is therefore ineffective in relation to compliance with the program guidelines

Integridade tissular de pacientes com úlceras venosas: um estudo baseado na Classificação dos Resultados de Enfermagem

The venous ulcer is an epidemiological problem of high prevalence, causing disability and dependence. Assess the tissue impairment level of patients with venous lesions, within a nursing referential, is relevant for the implementation of a directed assistance to specific clientele. Thus, this work aims to characterize the health status regarding the integrity the lower limbs skin of patients with venous ulcers, according to the of tissue integrity outcome indicators from the Nursing Outcomes Classification. A cross-sectional study conducted in a university hospital in Natal - Rio Grande do Norte. The sample consisted of 50 participants, selected through consecutive sampling. Data collection occurred through a interview and physical examination form and a operational definitions tool for indicators of the nursing Tissue Integrity outcome directed to patients with venous ulcer, applied from February to June 2012. Data analysis was done by descriptive statistics and nonparametric tests (Spearman, Kruskal-Wallis and Mann-Whitney tests). The project was approved by the Research Ethics Committee with protocol 608/11 and Presentation Certificate to Ethical Consideration No. 0038.0.294.000-11. The results were presented using three scientific articles derivatives of research. It was found that the indicators show moderate impairment, light and not impaired, as the median. The respondents had an average of 59.72 years, 66% female, 50% were retired, 60% with a partner, 44% had arterial hypertension, 26% allergies, 20% diabetes mellitus, 96% were sedentary, 14% drank alcohol and 6% were smokers. There was a statistically significant correlation of low intensity between age and hydration (p=0.032; rs=-0.304) and skin desquamation (p=0.026; rs=-0.316), family income and necrosis (p=0.012; rs=-0.353); Ankle Brachial Index and tissue perfusion (p=0,044; rs=-0,329); Diabetes Mellitus and texture (p=0.015) and tissue perfusion (p=0.026); allergy and texture (p=0.034), physical activity and hydration (p=0.034), smoking and thickness (p=0.018), and alcohol consumption and exudate (p=0.045). We conclude that the patients had light to moderate impairment, indicating a good state of health on the integrity of the skin of the lower limbs, according to the indicators of the outcome of tissue integrity Classification Nursing Outcomes valued in the present study. It is believed that the evaluation of impairment tissue using a self-nursing system and its relation with socioeconomic, clinical and risk factors are unique tools in the care planning and in the wound healing

Influência do hipoestrogenismo por ooforectomia na adaptação antioxidante em ratas wistar exercitadas regularmente

Post-menopause is a period of women s life cycle that is characterized by estrogen depletion and therefore increasing cardiovascular diseases, neurodegenerative disorders, urogenital atrophy, osteoporosis, hot flushes and sexual discomfort incidences. Estrogen is a hormone with comfirmed antioxidant action and its depletion is related to oxidative stress instalation and damaging various important biomolecules. Regular physical activity has been identified as a factor involved in reducing women s post-menopausal complications in addition to improving antioxidant defense by reducing the oxidative damage and consequently improving life s quality in this part of the population. This study aims to evaluate the influence of hypoestrogenism in antioxidant adaptation due to regular exercise, by determining reduced glutathione (GSH) and Thiobarbituric Acid Reactive Substances (SRAT) concentrations and antioxidant enzymes glutathione peroxidase (GPx), Superoxide Dismutase (SOD) and Catalase (CAT) activities in blood, brain and liver of rats. To achieve this goal we used 50 Wistar rats, weighing 180-250g which were divided into two groups, control - GC (25) and ooforectomized - GO (25). Each group was subdivided into five subgroups: Not-trained - S (5), Not-trained Acute Exercise - SEA (5), regular exercise 30 days - E30 (5), regular exercise 60 days - E60 (5) and regular exercise 90 days - E90 (5). Each of the three subgroups exercised regularly was subjected to acute exercise on the eve and the day of sacrifice to collect biological samples of blood, liver and brain and subsequent determination of SRAT concentration, GSH content and antioxidant enzymes GPx, SOD and CAT activities. The results indicated that the sedentary animals acutely exercised presented oxidative stress and regular physical activity led to antioxidant adaptation. In ooforectomized group the antioxidant adaptation seen in control animals showed to be impaired. Unlike the results from blood and liver, in brain there was a shield against oxidative damage originated by the exercise and that hypoestrogenism led to a loss of this natural antioxidant potential. Therefore, hypoestrogenism interferes negatively in antioxidant adaptation due to regular exercise

Doenças sem doentes: Ocorrência de Distúrbios Osteomusculares Relacionados ao Trabalho DORT nos operadores de caixa de um banco

The changes incurred in the financial system with the introduction of new technologies and new forms of administration of banks has caused impact on the health of workers. These changes, which passed in the process of work, generate a combined share of the risk factors that result in numerous injuries and illnesses among banks, notably between the operators of banks tellers. The Work-Related Musculoskeletal Disordes - WRMD represent a group of occupational diseases always present among these workers. Because of its high incidence and the amount of financial resour envolved to manage the problem has been the object of constant study. This paper aims to analyze the bank teller activity; search the occurrence of WRMD in the activity, identifying the factors determining the occurrence of WRMD in the activity and determine the real number of touchs on a keyboard made by the operator and propose solutions that influence the reduction of illness in the workplace of the bank teller. Methodological tools of ergonomics are used to provide a broad knowledge of aspects of work that have been studied and influential in the generation of occupational diseases studied. It was found that activity put workers to serious risk of occupational diseases. As the main contributory factors and determinants for this illness: the requirements and control the numbers daily endorsements; evaluation system based on performance targets for productivity; management system at time of service to customers; work with stressful factors (broken box); excess of time worked; furniture of workstations with ergonomic inadequacies and policy for the prevention of occupational diseases inefficient. They have also noted cases of illness for DORT workers without fulfilling the legal requirement of the issuance of the communication of labour accident and without the removal of the employee of the workplace

Correlação entre torque, equlíbrio e função do joelho após reconstrução do LCA

Background: Several studies emphasize the importance of assessing the knee function after anterior cruciate ligament (ACL) reconstruction. The influence of several variables on the function of these patients has been analyzed, but there is no consensus in the science literature. Purpose: To evaluate the correlation between the torque and balance on the knee function after ACL reconstruction. Methods: 23 males patients with ACL reconstruction were tested. The procedures of the study included analysis of concentric peak torque at 60o/s and 180o/s of quadriceps femoris and hamstring muscle with a isokinetic dynamometer. The balance in single-limb stance was measured with stabilometry. The functional performance were performed by two hop tests. To estimate the subjective function of the patients was applied Lysholm Knee Scoring Scale and a Global Rating scale. Results: The analysis of data showed a moderate positive correlation between knee extensor torque and functional performance tests (r= 0,48; p=0,02). A moderate negative correlation was found between the two variables of the stabilometry center of pressure and average speed of centre of pressure and the Global Rating scale (r = -0.4, p = 0,04 and r = -0,49, p = 0 ,02, respectively). No correlation was found between peak torque and balance in single-limb stance. Conclusion: The results of the present study suggest that knee extensor strength and postural balance have some influence on knee function in patients after ACL reconstruction

Tradução e adaptação da escala de dependência de substâncias do Millon Clinical Multiaxial III para o Brasil

Millon describes the normal personality by means of adaptation styles that are effective in normal environments and personality disorders such as unadapted operating styles. To operacionalize his theoretical model, Millon has built several instruments, including the Millon Clinical Multiaxial Inventory III (MCMI-III), wich consists of a self report inventory composed by 175 true or false response items, containing four verification scales, and others scales wich evaluates 14 personality patterns and 10 clinical syndromes. The Substance Dependence scale (T) is placed along with Clinical Syndromes scales. This research is justified by the lack of a Brazilian instrument to assess personality psychopathological aspects, and aims to translate and semantically adapt the MCMI-III to the Brazilian context, checking validity elements of the Substance Dependence scale, and developing a computer application for assisting the evaluation of assessment results. To this intent, 2.588 individuals data was collected, male and female, aged between 18 and 85 years, characterized as belonging to a clinical or non-clinical group, who took part in the survey via the internet or in person. Respondents completed the MCMI-III, a socio-demographic questionnaire and a subgroup also answered to the Goldberg General Health Questionnaire (GHQ). Besides descriptive statistics, we performed the analysis using the Student t test, principal components analysis and internal consistency. Despite difficulties related to translating very specific English terms, the assessment by judges, experts on Millon´s theory, and the back translation, attested the adequacy of the Brazilian version. Factorial analysis indicated the grouping of translated T scale items into three factors (social activities prejudice, lack of impulse control, and oppositional behavior), by presenting a single item on a fourth factor (apparently related to seeking pleasurable stimuli). The Cronbach alpha for this set of items was 0,82, indicating an acceptable scale reliability. The data analysis resulted in distinction of scores between clinical and non-clinical groups and between men and women; the relationship between high scores on the scale T and the other scales; scores of drug users according to the declared used substance; and the relationship between high scores on T and the verification of disorder or risk on GHQ mental health factor, indicating the instrument´s adequate sensistivity in identifying psychopathologies and the relationship between the different disorders or psychopathological personality patterns. Although further studies are necessary to develop the scores transformation factors, the computerized correction tool was adequate.

O acolhimento como promoção da saúde entre pacientes com câncer

Cancer has been affecting people all around the world; disregard sex, ethnicity or social class. Despite the fact it is not always deadly, to be diagnosed and treated of cancer brings a lot of physical, emotional and social suffering, specially for those with less economic resources. Considering the complexity of the problem, there has been perceived that medical treatment is not enough to support cancer patients. There is an increasing understanding about their necessity of integral care, supposed to be given by a multidisciplinary health care equip that can consider all the different aspects involved in the illness process. Everyone has a particular way of been ill or healthy, and gives different meanings to the experienced events. The starting point of the research was the contact with a called work `group of shelter', developed with cancer patients by a multidisciplinary health care equip working on the LIGA Norte Riograndense Contra o Câncer. The research goal is to identify meanings people give to the shelter they receive in the group and to understand the way they experience the disease. Considering it singularity of this process, one worked with individually half-structuralized interviews, carried through with nine patients of the chemotherapy clinics and suck, that they had passed for the experience of the group of shelter, having approached getting ill, the treatment, the shelter and the recreation of the psychosocial processes (or not) after all this process. It was chosen as focus of analysis the creation of psychosocial processes and production of felt of these social actors through its discourse analysis perspective, boarded in accordance with the following thematic axles: the experience of the cancer, the shelter and recreation of the psychosocial processes the life. It was found that shelter has an extensive meaning going beyond the the group and involving others besides the multidisciplinary health care equip, and being important to give each patient the best possible benefit. It was also identified the importance of other social actors, such as relatives, friends and neighbors; added of religious faith, mentioned by all interviewees. It is to be considered the recovering capacity shown by eight interviewees, demonstrated by changing the way of interacting with others, getting new values and behaviors, and demonstrating more wisdom. We can consider the possibility of making this strategy to become part of the everyday practices of others health services working with cancer patients, what we think can help to minimize their suffering

Multicast packing problem: abordagem multiobjetivo

This work presents a algorithmic study of Multicast Packing Problem considering a multiobjective approach. The first step realized was an extensive review about the problem. This review serverd as a reference point for the definition of the multiobjective mathematical model. Then, the instances used in the experimentation process were defined, this instances were created based on the main caracteristics from literature. Since both mathematical model and the instances were definined, then several algoritms were created. The algorithms were based on the classical approaches to multiobjective optimization: NSGA2 (3 versions), SPEA2 (3 versions). In addition, the GRASP procedures were adapted to work with multiples objectives, two vesions were created. These algorithms were composed by three recombination operators(C1, C2 e C3), two operator for build solution, a mutation operator and a local search procedure. Finally, a long experimentation process was performed. This process has three stages: the first consisted of adjusting the parameters; the second was perfomed to indentify the best version for each algorithm. After, the best versions for each algorithm were compared in order to identify the best algorithm among all. The algorithms were evaluated based on quality indicators and Hypervolume Multiplicative Epsilon

Análises clínicas, radiográfica e microscópica de molares permanentes sem ou com lesão de cárie na superfície oclusal

O presente trabalho, objetivou avaliar comparativamente o diagnóstico clínico, radiógráfico e histológico de molares permanentes humanos sem ou com lesão de cárie na superfície oclusa!. Vinte e quatro dentes que estavam armazenados em formalina a 10% foram selecionados e em seguida submetidos a um exame clínico, através da inspeção visual, onde foram separados em 3 grupos: grupo 1 (G1), formado por dentes hígidos; grupo 2(G2), por dentes com pigmento na superfície oclusal e grupo 3(G3), aqueles com lesão de cárie na oclusal. Este exame foi realizado com auxílio de luz artificial proveniente de um refletor odontológico, sem qualquer manipulação da superfície. Para cada dente foram realizados duas tomadas radiográficas com e sem tela milimetrada, no sentido vestibulo lingual por um dos avaliadores, simulando uma radiografia interproximal, onde o feixe incidiu perpendicular ao longo eixo do dente. Em seguida os dentes foram preparados histomorfologicamente para coloração com hematoxilina e eosina e análise microscópica. Pela avaliação dos resultados a partir da amostra de 100%, foi possível concluir: 1) Os dentes clinicamente considerados hígidos (G1) apresentaram radiograficamente 74,99% de ausência de imagem radiolúcida e em 25% presença desta imagem na Junção Amelo¬dentinária e microscopicamente ausência de cárie em 100%; 2) os dentes que clinicamente apresentaram fissura pigmentada' (G2) notou-se em 33,33%, ausência da imagem radiolúcida e em 66,66% presente esta imagem na junção amelodentinária, 100% de ausência de cárie através da análise microscópica; 3) clinicamente, os dentes que apresentaram lesão de cárie (G3), radiograficamente foram comprovados 100% de imagem radiolúcida sugestiva de cárie e microscopicamente dos 100% destas, foram considerados cáries rasa (16,66%), média (61,10%) e profunda (22,22%) respectivamente

Aplicação do Sensoriamento Remoto e do Sistema de Informações Geográficas na Detecção de Manchas de Óleo na Região do Pólo de Exploração de Guamaré, R.N.

Objective to establish a methodology for the oil spill monitoring on the sea surface, located at the Submerged Exploration Area of the Polo Region of Guamaré, in the State of Rio Grande do Norte, using orbital images of Synthetic Aperture Radar (SAR integrated with meteoceanographycs products. This methodology was applied in the following stages: (1) the creation of a base map of the Exploration Area; (2) the processing of NOAA/AVHRR and ERS-2 images for generation of meteoceanographycs products; (3) the processing of RADARSAT-1 images for monitoring of oil spills; (4) the integration of RADARSAT-1 images with NOAA/AVHRR and ERS-2 image products; and (5) the structuring of a data base. The Integration of RADARSAT-1 image of the Potiguar Basin of day 21.05.99 with the base map of the Exploration Area of the Polo Region of Guamaré for the identification of the probable sources of the oil spots, was used successfully in the detention of the probable spot of oil detected next to the exit to the submarine emissary in the Exploration Area of the Polo Region of Guamaré. To support the integration of RADARSAT-1 images with NOAA/AVHRR and ERS-2 image products, a methodology was developed for the classification of oil spills identified by RADARSAT-1 images. For this, the following algorithms of classification not supervised were tested: K-means, Fuzzy k-means and Isodata. These algorithms are part of the PCI Geomatics software, which was used for the filtering of RADARSAT-1 images. For validation of the results, the oil spills submitted to the unsupervised classification were compared to the results of the Semivariogram Textural Classifier (STC). The mentioned classifier was developed especially for oil spill classification purposes and requires PCI software for the whole processing of RADARSAT-1 images. After all, the results of the classifications were analyzed through Visual Analysis; Calculation of Proportionality of Largeness and Analysis Statistics. Amongst the three algorithms of classifications tested, it was noted that there were no significant alterations in relation to the spills classified with the STC, in all of the analyses taken into consideration. Therefore, considering all the procedures, it has been shown that the described methodology can be successfully applied using the unsupervised classifiers tested, resulting in a decrease of time in the identification and classification processing of oil spills, if compared with the utilization of the STC classifier
