A representação social de disciplinas didático-pedagógicas no contexto da formação inicial docente: um entremear de saberes

We seek, through this study, to analyze about social representation that the students of licentiate degree course of the Federal Institute of Education, Science and Technology of Rio Grande do Norte - IFRN - have about didactic-pedagogical subjects. We utilize the Social Representations Theory (MOSCOVICI, 2009; 2012; JODELET, 2001) as a theoretical and methodological contribution and as aim, we identify this social representation and understand how it is influenced by the formation of these undergraduates. So we developed the research under the seven undergraduate classroom courses offered by IFRN, namely: Biology, Spanish, Physics, Geography, Computer Science, Mathematics and Chemistry, covering units located both in the capital and in the countryside. While methodological approach we used the Procedure of Multiple Classification (PMC) - (ROAZZI, 1995), whose realization requires a set of words achieved through of Free Technique of Words Association - FTWA - (ABRIC, 1998). For this realization we have a total of one hundred twenty (120) participants, with thirty (30) in FTWA and other stage in the realization of free classification and directed that correspond to the MPR. Achieved the empirical data, we use the analysis of content (BARDIN, 2011; FRANCO, 2007) and multidimensional (ROAZZI, 1995) for the course of his interpretation. Finally, we identify the social representation of didactic and pedagogical subjects centered around the idea that it is through these subjects that can achieve the profile of "good professional" as one who gathers knowledge and attributes required for the full development of teaching involving capabilities it and characteristics that mark the sense of professionalism. Furthermore, we found that the anchoring social representation on the understanding that these disciplines "teach the teacher to be" in the image and its objectification of the "good teacher", ie, one that reaches through the training process and experiences, qualities that make it unique and able to carry full professional. Still see that the actions of the teacher trainer affects the way students perceive, assume and engage in the study of teaching and pedagogical subjects and it reflects significantly the social representation then created

A Tessitura de sentidos: representação social de licenciados do curso deletras da UFRN sobre o ensinar

En esta investigación, se busca comprender los procesos de formación de pregrado del Curso de Cartas da UFRN, de estas representaciones sociales acerca de los estudiantes de enseñanza. Por lo tanto, el objetivo fue conocer y analizar las representaciones sociales de curso de pregrado UFRN Cartas sobre la enseñanza. Por lo tanto, se aplica la Técnica de Libre de Palabras Asociación (TALP) con 20 participantes, después de haber sido probados individualmente, utilizando como estímulo palabra "enseñar" y limitar el número de invocaciones a 03 palabras por participante. Esta técnica fue elegida porque es una técnica proyectiva que permite la reducción y racionalización permite acceder al campo semántico de las representaciones sociales, en nuestro caso, en la enseñanza del de pregrado do Curso de Cartas da UFRN. Por lo tanto, llegamos a total de 60 llamadas, análisis de frecuencia después de 41 y 24 después de un análisis del significado que se utilizaron en otro procedimiento aplicado en esta investigación, las calificaciones de Procedimiento de Múltiples Calificaciones (PCM). Estas palabras, sobre la base de las justificaciones de las evocaciones y significados que atribuyen participantes en la investigación, se dividieron en 4 campos semánticos: Campo 1: Aspectos técnicos de la enseñanza, Campo 2: aspectos volitivos, Campo 3: aspectos relacionales de la enseñanza y de Campo 4: Elementos del campo. El PCM se aplicó de forma individual, con 50 estudiantes. Para el análisis de los datos generados, utilizamos Análisis Multidimensional (MDS) para la Escala Multidimensional de Evaluación Análisis gratuito (MSA: Multidimensional Scalogram Analysis) y el análisis de clasificación selectiva de los espacios menores (SSA: Smallest Space Analysis).

Del análisis del contenido de las justificaciones de la PCM, llegó a 5 categorías, a saber: Hacer la enseñanza, la faceta negativa, Escuela, Formación y faceta afectiva del profesor. El TALP aporta pruebas de que algunos de estos estudiantes ve la oportunidad de adquirir unos conocimientos en esta área, la formación en un nivel superior, como quieran, simplemente tienen un título universitario para realizar licitación abierta. El PCM nos ha hecho comprender que el contenido representacional en cuestión se configura desde el universo consensual conectado a la profesión y la formación. Por lo tanto, podemos decir que los titulares de licencias con respecto al tema estudiado anclar la representación social de "enseñar" a la imagen de ser un maestro y objetivar la imagen de la profesión

Entre flores e espinhos: a atuação do técnico em enfermagem na estratégia saúde da família

It is about a study of an exploratory/descriptive type with a qualitative approach whose aim was to analyze the actuation of nursing technicians in Family Health Strategy (FHS), taking into consideration the defined attributions by the Ministry of Health (MH). Thus, it was sought to identify what activities they carry out, the difficulties encountered, what contributed to their professional performance, and what vision they have about FHS and about themselves in the context. Based on the assumption that the practice of Nursing Technician is not still geared to completeness and that the developed actions by this professional are predominantly individual and curative. We know that FHS proposes the work organization as a team, with territory definition, prioritization of promotion actions, protection and recovery of the individual/family/community health, choosing as a central point the establishment of entails between the professionals and the same ones. However, the team work pass through interdisciplinary, tying and competence, starting making the difference in the way of thinking and doing health. To the accomplishment of this study were interviewed twenty one Nursing Technicians of Family Health Units from Sanitário Oeste district in Natal-RN, using semistructured instrument. From the analysis, three empiric categories emerged: starting from the first, The reality of a dream: what FHS is for the Nursing Technician, we obtained two classifications: one inherent to the own conception they have about FHS, nominated The realization of a dream in the possible and another that corresponds to what they think about FHS, while project that doesn't take place fully, denominated of The beauty of a dream that doesn't take place. The second category was The FHS: a dream built in the daily of Nursing Technician treats of the day by day information of that professional; the activities they perform and how those are established. This created three other items, to know: The role of a Nursing Technician: a project that became routine; The pre-determined role of a Nursing Technician: the scale as factor of (non-)autonomy; and, Knowledge about the practice in FHS: challenges that are presented to the role of Nursing Technician. The third category, denominated of Charms and disenchantment in the beginning of a new practice, it is related to the facilities or difficulties in professional's actuation and how he sees himself in the context. From it emerged the "flowers" and the "thorns" found on the construction of a dream, which gave this study the title. The results indicate that, being considered the characteristics of researched professional category, it becomes fundamental the resizing of labor relations in FHS, being imperative that new glances is conducted, so that the way as those Nursing Technicians interacts with the families can become compatible, together with the team, as well as to return the attention for their possibilities and limits in face of the work process in FHS. Besides, it is necessary changes in the professional formation, so that it can guarantee the conceptual bases in the construction of new practices, seeking to answer to the model of current attention.

Hipertensão arterial e fatores de risco em servidores atendidos pelo departamento de assistência da Universidade Federal do Rio Grande do Norte

Systemic arterial hypertension is a multifactorial disease that contributes to the country´s high cardiovascular morbi-mortality rates. Considering that hypertension affects individuals in their most productive age while facing work and living risk factors, it is important to investigate its occurrence and predisposing factors in different occupational segments. The objective of this study was to identify the prevalence of hypertension among workers attended to in a medical service of a public university, their hypertension levels, the risk factors present, and their knowledge of the factors that influence the arterial pressure. The epidemiologic study was conducted in the Health Department of the Federal University of Rio Grande do Norte with 102 workers that sought care in the medical clinic during the months of March to May 2009. Data were collected by means of a questionnaire and measurements of systolic and diastolic arterial pressure (SAP and DAP) that were classified in stages according to the Brazilian Society of Hypertension and the degree of risk for cardiovascular events according to the criteria of the Brazilian Society for Cardiology. Data were analyzed using descriptive statistics. The workers were, on average, 54 years of age; the majority (67%) was male and had primary or middle educational level; they worked mainly in supplemental units and deanship offices conducting different functions such as security guards, administrative assistants, health auxiliaries and constructions workers; 48 (47%) of the workers identified themselves as hypertensive for 8 years on average, with the majority executing hard labor and administrative functions. Among the workers with hypertension, the number of the pressure levels classified as pre-hypertensive, stage I and II were: (12% in the SAP and 20% in the DAP); (16% in the SAP and 9% in the DAP); and (15% in the SAP and 5% in the DAP), respectively. The workers that did not identify themselves as hypertensive presented classifications with greater frequencies were: normal (16% in the SAP and 30% in the DAP); and pre-hypertensive (21% in the SAP and 16% in the DAP). The risk factors identified in more than 50% of the workers were: tobacco smoking, alcohol consumption and indices of being overweight, although physical activities are also present. Of the 48 workers diagnosed as hypertensive, those that had 5 risk factors present and limitrophic pressure levels (12%), in stage I hypertension (16%) and stage II hypertension (15¨%) were categorized as being in high risk for vascular events. The number of workers that indicated they had knowledge of the factors that influence their hypertension was less than 39% for each factor. It is concluded that there is a high prevalence of systemic arterial hypertension in the university workers, even amongst those already under treatment. They constitute a population at risk considering their age group, their work functions, and their inadequate life habits. Health care of these hypertensive workers that seek attention in the Health Department is an important aspect of the internal workers health policy in the institution. Educational interventions are recommended for the improvement of quality of life and of work in these workers

Estudo sistemático de estrelas variáveis na era dos grandes surveys

The interest in the systematic analysis of astronomical time series data, as well as development in astronomical instrumentation and automation over the past two decades has given rise to several questions of how to analyze and synthesize the growing amount of data. These data have led to many discoveries in the areas of modern astronomy asteroseismology, exoplanets and stellar evolution. However, treatment methods and data analysis have failed to follow the development of the instruments themselves, although much effort has been done. In present thesis, we propose new methods of data analysis and two catalogs of the variable stars that allowed the study of rotational modulation and stellar variability. Were analyzed the photometric databases fromtwo distinctmissions: CoRoT (Convection Rotation and planetary Transits) and WFCAM (Wide Field Camera). Furthermore the present work describes several methods for the analysis of photometric data besides propose and refine selection techniques of data using indices of variability. Preliminary results show that variability indices have an efficiency greater than the indices most often used in the literature. An efficient selection of variable stars is essential to improve the efficiency of all subsequent steps. Fromthese analyses were obtained two catalogs; first, fromtheWFCAMdatabase we achieve a catalog with 319 variable stars observed in the photometric bands Y ZJHK. These stars show periods ranging between ∼ 0, 2 to ∼ 560 days whose the variability signatures present RR-Lyrae, Cepheids , LPVs, cataclysmic variables, among many others. Second, from the CoRoT database we selected 4, 206 stars with typical signatures of rotationalmodulation, using a supervised process. These stars show periods ranging between ∼ 0, 33 to ∼ 92 days, amplitude variability between ∼ 0, 001 to ∼ 0, 5 mag, color index (J - H) between ∼ 0, 0 to ∼ 1, 4 mag and spectral type CoRoT FGKM. The WFCAM variable stars catalog is being used to compose a database of light curves to be used as template in an automatic classifier for variable stars observed by the project VVV (Visible and Infrared Survey Telescope for Astronomy) moreover it are a fundamental start point to study different scientific cases. For example, a set of 12 young stars who are in a star formation region and the study of RR Lyrae-whose properties are not well established in the infrared. Based on CoRoT results we were able to show, for the first time, the rotational modulation evolution for an wide homogeneous sample of field stars. The results are inagreement with those expected by the stellar evolution theory. Furthermore, we identified 4 solar-type stars ( with color indices, spectral type, luminosity class and rotation period close to the Sun) besides 400 M-giant stars that we have a special interest to forthcoming studies. From the solar-type stars we can describe the future and past of the Sun while properties of M-stars are not well known. Our results allow concluded that there is a high dependence of the color-period diagram with the reddening in which increase the uncertainties of the age-period realized by previous works using CoRoT data. This thesis provides a large data-set for different scientific works, such as; magnetic activity, cataclysmic variables, brown dwarfs, RR-Lyrae, solar analogous, giant stars, among others. For instance, these data will allow us to study the relationship of magnetic activitywith stellar evolution. Besides these aspects, this thesis presents an improved classification for a significant number of stars in the CoRoT database and introduces a new set of tools that can be used to improve the entire process of the photometric databases analysis

Uma nova forma de calcular os centros dos Clusters em algoritmos de agrupamento tipo fuzzy c-means

Clustering data is a very important task in data mining, image processing and pattern recognition problems. One of the most popular clustering algorithms is the Fuzzy C-Means (FCM). This thesis proposes to implement a new way of calculating the cluster centers in the procedure of FCM algorithm which are called ckMeans, and in some variants of FCM, in particular, here we apply it for those variants that use other distances. The goal of this change is to reduce the number of iterations and processing time of these algorithms without affecting the quality of the partition, or even to improve the number of correct classifications in some cases. Also, we developed an algorithm based on ckMeans to manipulate interval data considering interval membership degrees. This algorithm allows the representation of data without converting interval data into punctual ones, as it happens to other extensions of FCM that deal with interval data. In order to validate the proposed methodologies it was made a comparison between a clustering for ckMeans, K-Means and FCM algorithms (since the algorithm proposed in this paper to calculate the centers is similar to the K-Means) considering three different distances. We used several known databases. In this case, the results of Interval ckMeans were compared with the results of other clustering algorithms when applied to an interval database with minimum and maximum temperature of the month for a given year, referring to 37 cities distributed across continents

O símbolo esvaziado: a teoria do romance do jovem György Lukács

O presente artigo investiga como A teoria do romance (1916) de G. Lukács, um texto fragmentado e de ocasião, tornou-se um clássico da reflexão sobre a modernidade. Para Lukács, o romance é a forma artística que corresponde à fratura entre o sujeito e o mundo, vivida pelo homem contemporâneo. Utilizando o conceito de símbolo esvaziado este texto apreende em que medida o autor ao rever as classificações anteriores sobre o gênero romance, perpetua a tradição romântica ou rompe com ela, elaborando conceitos originais para a compreensão da modernidade na literatura.

CrossMDA2: Uma abordagem para minimizar o problema da fragilidade de pointcuts na evolução de sistemas orientados a aspectos

This work proposes a model based approach for pointcut management in the presence of evolution in aspect oriented systems. The proposed approach, called conceptual visions based pointcuts, is motivated by the observation of the shortcomings in traditional approaches pointcuts definition, which generally refer directly to software structure and/or behavior, thereby creating a strong coupling between pointcut definition and the base code. This coupling causes the problem known as pointcut fragility problem and hinders the evolution of aspect-oriented systems. This problem occurs when all the pointcuts of each aspect should be reviewed due to any software changes/evolution, to ensure that they remain valid even after the changes made in the software. Our approach is focused on the pointcuts definition based on a conceptual model, which has definitions of the system's structure in a more abstract level. The conceptual model consists of classifications (called conceptual views) on entities of the business model elements based on common characteristics, and relationships between these views. Thus the pointcuts definitions are created based on the conceptual model rather than directly referencing the base model. Moreover, the conceptual model contains a set of relationships that allows it to be automatically verified if the classifications in the conceptual model remain valid even after a software change. To this end, all the development using the conceptual views based pointcuts approach is supported by a conceptual framework called CrossMDA2 and a development process based on MDA, both also proposed in this work. As proof of concept, we present two versions of a case study, setting up a scenario of evolution that shows how the use of conceptual visions based pointcuts helps detecting and minimizing the pointcuts fragility. For the proposal evaluation the Goal/Question/Metric (GQM) technique is used together with metrics for efficiency analysis in the pointcuts definition

A representação social de educação tecnológica de docentes da Rede Federal de Educação Profissional e Tecnológica: CEFETs do Rio Grande do Norte

The aim of this study was to investigate the social representation of technological education teachers at the Federal Technological Education Network. The survey was conducted from 2007 to 2010, and the respondents were 275 teachers, 135 of the Federal Center for Technological Education (CEFET in portuguese) in the state of Amazonas, in Manaus unit headquarters; 140 of the CEFET in the state of Rio Grande do Norte, a unit based in Natal. We adopt the concept of technological education as the top level of professional education, that is to say, the undergraduate programs of short duration called technological courses. The Federal Technological Education Network gathers hundreds of related institutions, coordinated and supervised by the Office of Vocational and Technological Education of the Ministry of Education. Although many of these institutions offer courses in technology education, no research addressing this subject from the perspective of Social Representations Theory (SRT) was found in the literature. We seek to unravel the social representation of technological education of the teachers by adopting the procedural approach of SRT. This is a qualitative approach, focusing on significant aspects of the representative activity and the formation mechanisms of the representation. Therefore, we search the socio-genesis of the representation in the articulations between discourses, social institutions and practices. We initiated the research through applying critical reading and an analytical perspective on the historical and regulatory documents of technological education in Brazil, from the early twentieth century to the present day. We adopt the Procedure for Multiple Classifications (PMC) from the Free Words Association Technique (FWAT) to access the elements of representational content. For the analysis of the data obtained with FWAT and selection of major words / phrases pertinent to the semantic field of education technology, we used Hamlet II software. For the data analysis of PMC and Free Classification (FC) we used the SPSS ® (Statistical Package for the Social Sciences) version 17.0 and used the method of multidimensional scaling - Multidimensional scaling - (MDS). The output from the central MDS takes the form of a set of scatterplots - "perceptual maps" - of which the points are the elements of the representational content. For the FC data analysis we used the Scalogram Multidimensional Analysis (SMA) - which makes use of the original data in its raw form and allows categorical data to be interpreted in the map as measures of (di)similarity. In order to help with the understanding of the settings of the perceptual maps of FC, we used the Content Analysis of the discourse fragments of the teachers interviewed. The results confirm our initial hypothesis regarding the presence of a single plot among the socio-cognitive study subjects, which is the basis for a social representation of technological education in line with the historic assumption of the dichotomy between mental and manual labor. In spite of the three merging representational elements of the representational content, the perceptual maps compiled from the MSA statistics corroborates the dichotomy, with the exception of the map relating to the subgroup of teachers belonging to the humanities

Comitês de Classificadores para o Reconhecimento Multibiométrico em Dados Biométricos Revogáveis

This work discusses the application of techniques of ensembles in multimodal recognition systems development in revocable biometrics. Biometric systems are the future identification techniques and user access control and a proof of this is the constant increases of such systems in current society. However, there is still much advancement to be developed, mainly with regard to the accuracy, security and processing time of such systems. In the search for developing more efficient techniques, the multimodal systems and the use of revocable biometrics are promising, and can model many of the problems involved in traditional biometric recognition. A multimodal system is characterized by combining different techniques of biometric security and overcome many limitations, how: failures in the extraction or processing the dataset. Among the various possibilities to develop a multimodal system, the use of ensembles is a subject quite promising, motivated by performance and flexibility that they are demonstrating over the years, in its many applications. Givin emphasis in relation to safety, one of the biggest problems found is that the biometrics is permanently related with the user and the fact of cannot be changed if compromised. However, this problem has been solved by techniques known as revocable biometrics, which consists of applying a transformation on the biometric data in order to protect the unique characteristics, making its cancellation and replacement. In order to contribute to this important subject, this work compares the performance of individual classifiers methods, as well as the set of classifiers, in the context of the original data and the biometric space transformed by different functions. Another factor to be highlighted is the use of Genetic Algorithms (GA) in different parts of the systems, seeking to further maximize their eficiency. One of the motivations of this development is to evaluate the gain that maximized ensembles systems by different GA can bring to the data in the transformed space. Another relevant factor is to generate revocable systems even more eficient by combining two or more functions of transformations, demonstrating that is possible to extract information of a similar standard through applying different transformation functions. With all this, it is clear the importance of revocable biometrics, ensembles and GA in the development of more eficient biometric systems, something that is increasingly important in the present day

Caracterização físico-química de farinhas de mandioca de diferentes localidades do Brasil

A farinha de mandioca (Manihot esculenta Crantz) é produzida em diferentes regiões do Brasil e faz parte do hábito alimentar do brasileiro. Caracteriza-se num alimento de alto valor energético, possui teor elevado de amido, contém fibras e alguns minerais como potássio, cálcio, fósforo, sódio e ferro. Entre os diferentes estados, os do Norte e Nordeste consomem quantidades de farinha de mandioca bem maiores que os demais. Frente à importância econômica e nutricional deste produto, com o presente trabalho, objetivou-se caracterizar farinhas de mandioca de diferentes estados do País, esperando com isso fornecer informações referentes à composição e às características físico-químicas do produto, tanto para as indústrias produtoras quanto aos consumidores. Os resultados obtidos mostraram que, quanto à composição centesimal, as farinhas analisadas diferem entre si e entre as regiões produtoras, inclusive para classificações de mesmo grupo e subgrupo. Para proteínas e acidez, as farinhas não estão de acordo com os limites da legislação. As farinhas apresentam teores baixos a moderados de fibras, contudo, devido ao seu amplo consumo, contribui como importante fornecedor de fibras na alimentação. A classificação de algumas farinhas quanto à cor não está de acordo com as análises de seus componentes de cromaticidade.

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

Miomas submucosos: classificação pré-operatória para avaliação da viabilidade da cirurgia histeroscópica

OBJETIVO: desenvolver uma nova classificação pré-operatória dos miomas submucosos para avaliação da viabilidade e do grau de dificuldade da miomectomia histeroscópica. MÉTODOS: conduzimos um estudo onde quarenta e quatro pacientes foram submetidas a ressecção histeroscópica de 51 miomas submucosos. Foram considerados a possibilidade da ressecção total do mioma, o tempo cirúrgico, o balanço hídrico e a incidência de complicações. Os miomas foram classificados pela classificação da sociedade Européia de Cirurgia Endoscópica (CSECE) e pela Classificação Proposta (CP) pelo nosso grupo, que, além do grau de penetração do mioma no miométrio, adiciona como parâmetros a extensão da base do mioma em relação à parede do útero, o tamanho do nódulo em centímetros e a topografia na cavidade uterina. Para análise estatística foram usados o teste de Fisher, o teste t de Student e a análise de variância. Foi considerado estatisticamente significativo quando o valor de p-valor foi menor que 0,05 no teste bicaudal. RESULTADOS: em 47 miomas a cirurgia histeroscópica foi considerada completa. Não houve diferença significativa entre os três níveis (0, 1 e 2) da CSECE. Pela CP, a diferença quanto ao número de cirurgias completas foi significativa (p=0,001) entre os dois níveis (grupos I e II). A diferença da duração da cirurgia quando se compara as duas classificações foi significativa. em relação ao balanço hídrico, apenas a CP mostrou diferenças entre os níveis (p=0,02). CONCLUSÕES: a CP inclui mais dados sinalizadores das dificuldades da miomectomia histeroscópica do que a CSECE, atualmente em uso. Deve ser enfatizado que o número de miomectomias histeroscópicas usado para essa análise foi modesto, sendo interessante a avaliação do desempenho dessa classificação em séries maiores de casos.
