This work is part of the research line "Fundamentals of educational processes" and discusses the meaning of philosophical paideía, the human n' The Republic. Of bibliographical and theoretical in the Greek sense of the term, this work is a quest for the meaning of being and education. This sense, we now seem to have lost sight of their arkhé, guiding principle of the formation of man, in view of the ideal of paideía. At that time the discourse and pedagogical practice restricted to limited understanding and poor education confused with the school as if these terms were synonymous, Greek philosophy teaches that the télos, the end of education is the conversion of the soul to the Well. Socrates leads the educator of today to gestate ideas and concepts thinking of the real through lógos, and questioning established knowledge by the exercise of maiêutica. Education is fully realized as periagogé, motion of rotating the look from the sensible to the intelligible plan, rising to perfection, the areté is the virtue which leads to overcoming limits and allows the realization of the potentialities of man in the tireless search for eudaimonía, happiness. To think with Plato the problems of education means to interrogate the sense of collective life...

This study investigated the construction and mobilization of teaching knowledge to train chemistry teachers for school inclusion. The research was especially guided by aspects intrinsic to qualitative approach. We chose an action-research, given the purpose of providing to those involved the conditions to think, reflect and discuss the nature and complexity of real problems we are experiencing. This research was developed in two spiral cycles of action-research. The first cycle included the planning and development of the free core subject entitled Foundations of Inclusive Education (FIE) in 2010, and the second cycle was the development of supervised training at the Brazilian Center for Support and Rehabilitation of the Visually Impaired (CEBRAV) in 2011. The participants were students of the subject FEI, trainees of the Education Degree in Chemistry who have developed their internships at CEBRAV and visually impaired students of CEBRAV. The instruments for data collection were, for the 1st cycle, the collective diaries and in the 2nd cycle, we use the collective diaries and transcripts of audio and video recordings of pedagogical interventions (PI) performed in CEBRAV. The collected data were analyzed using content analysis technique (CA) and through the transcripts of PI. The narratives produced in collective diaries indicated that students of the subject FEI have appropriated the discussions promoted in groups...

The religious feasts, in a general set, are related to the celebrations and tributes done to the worshiped deities in any other religious follow-up. The present study emphasizes the religious feasts as a social cultural practice that spatializes in Goiás State. The feasts space materializes itself in the scenery, in the territory and in the territorialities construction. The chosen places to the research development are the villages of Muquém and Posse D Abadia, respectively set in the goiano boroughs of Niquelândia and Abadiânia and the town of Trindade. The catholic religious feasts are manifestations that boost these boroughs spaces, revealing, in their organization, a religious identity expressed in the studied places territory. The work main goal is the comprehension of how it occurs the patron feasts spatialization and its reflexes in the formation and structuration of the goiano territorial and cultural space. With this study it is searched to present a theoretical-methodological reflection about the patron feasts traditions that sustain a territorial identity in the State. For this identity, the patron is the faith, territory and the feast centrality. The territory is built and donated to the patron, which domain is effective with the possession and the power as protector of the mentioned places. The territorial identity is placed as a religious identity assigned to this patron. The formed identity...

The aim of this research is to investigate the possible relationships between visual arts and literature from the study of works produced by the Brazilian artists José Roberto Aguilar (1941-) and Lenir de Miranda (1945-). Both have appropriated the character Ulysses from Homer's Odyssey and produced works using painting. Based on a literature review focused on the history of art, contemporary art theory and intersemiotic translation studies, we focus our study around the concepts of appropriation and expanded field. We conclude that the literary signs are appropriated for the artists in the field expanded of contemporary art as a poetic possibility.; O objetivo dessa pesquisa é investigar as possíveis relações entre artes visuais e literatura a partir do estudo de obras produzidas pelos artistas brasileiros José Roberto Aguilar (1941-) e Lenir de Miranda (1945-). Ambos se apropriaram do personagem Ulisses, da Odisseia de Homero, e produziram séries de pinturas. Com base em uma revisão bibliográfica centrada na história da arte, na teoria da arte contemporânea e nos estudos de tradução intersemiótica, centramos nosso estudo em torno dos conceitos de apropriação e de campo ampliado. Concluímos que os signos literários são apropriados pelas artes visuais dentro do campo ampliado como uma possibilidade poética.

Goiânia has many conflicts that result from the misuse of water. Their streams, with the increasing urbanization, suffered degradation in water quality. The aim of this study was to evaluate the different socio-environmental characteristics and its influence on the biotic and abiotic factors and the influence of human disturbance on the environment. Sites along the stream were selected for water sampling and also were used qualitative methodologies and techniques like questionnaires and interviews. Thus, this work scaled and assessed the importance of Cascavel stream for farmers who occupy the region close to this water source, located between Jardim Atlântico and Vila Rosa, Goiânia, Goiás. Questionnaires were applied, with the surrounding residents and gardeners who live in this area and carried out the diagnosis of biotic and abiotic factors, thus verifying the environmental characteristics. The study evaluated the whole process of human disturbance of the Cascavel stream until today. It appeared that the inhabitants of the surrounding ranchers and yearn for the improvement of the environment, because they live and depend on it, but want to be targeted for this benefit, as learning new techniques for planting or replanting the banks of the stream. It was further observed that the government...

The human papillomavirus (HPV) is a major etiologic factor in the development of cervical cancer, DNA virus primarily infects the epithelium and may induce benign and malignant lesions of the mucous membranes and skin. Carcinogenesis is a multistep process that involves both changes genetic and epigenetic. The two changes epigenetic most studied are DNA methylation and histone acetylation. DNA methylation may be related development to cancer, and their presence or absence can affect the prognosis. The objective of this study was to evaluate the prognosis of patients with cervical cancer in stages I and II through the verification of HPV high and low risk, and the presence and absence of genes methylated and unmethylated RARβ, TIMP3, CDH1 and MGMT. We analyzed 129 records and samples of paraffin embedded biopsies of patients with cervical cancer in stages I and II. Detection of HPV - DNA was performed by PCR for HPV DNA of low and high oncogenic risk and MSP-PCR to detect the genes methylated or not, RARβ, TIMP3, CDH1 and MGMT. The calculation of survival used the Kaplan-Meier method and the log-hank test to compare means of survival between the prognostic factors for cervical cancer. The overall survival at 60 months of patients with the presence of RARβ...

The expansion of the culture of sugar cane in Brazil is being driven towrds the Brazilian Midwest, particularly in the states of Mato Grosso do Sul (MS) and Goiás, since the end of last century. Goiás stands out in this process, but is now among the three states with the largest cultivated area and production. South mesoregion excels, especially micro-Quirinopolis (MRQ), where the process began in 2004, replacing grain areas and pastures. This research aims to analyze the influence of different management practice in the cultivation of cane sugar in the MRQ, using sensitive biological and physico-chemical indicators of water quality and soil, to contribute to sustainable models with parameters that sugarcane expansion. Eight sampling sites were selected in areas occupied by soil type Red Oxisol dystrophyc and distroferric, with previous uses of soybeans, pasture and pasture / soybean, and in parallel, two profiles as a reference, with native vegetation, the type Semidecidual Forest, once dominant. Were also selected two stocks next crop of sugar cane, collections with the Montate and downstream of each channel. Descriptions and Samples of soil and water were carried out in September 2010 and March 2011. Proceeded physical...

v.16, n.4, p. 538-547 out./dez. 2015.; Canine visceral leishmaniasis (CVL) is a disease with multisystemic injuries, and among the various tissues affected, the third eyelid (TE) is often involved. This ocular adnexa has been studied for the leishmaniasis pathogenesis elucidation and for diagnosis advance. This study aimed to carry out the parasite immunodetection and evaluate histologic lesions in TE of Leishmania (leishmania) chagasi naturally infected dogs. Twenty-six TE samples from infected dogs were submitted to histologic evaluation and to immunohistochemistry for Leishmania sp. The main lesion observed in the third eyelid conjunctiva (TEC) was lymphoplasmacytic inflammation, with Mott cells and parasitized histiocytes. Additionally, loss of epithelial stratification, ulceration, goblet cells thinning or hyperplasia were often found. The same inflammatory pattern was observed in the third eyelid lacrimal gland (TELG), often accompanied by acinar atrophy and secretory ducts dilatation. Immunohistochemistry revealed parasitism in all samples, in different intensities.; Programa de Apoio à Publicações Periódicas Científicas (PROAPUPEC) da UFG;CNPq; CAPES; A leishmaniose visceral canina (LVC) é uma doença que envolve lesões multissistêmicas e...

v.10, n. 3, p. 01-18, jul./set., 2015.; The aim of this study is to determine the mechanical behavior of precast mortar panels containing expanded vermiculite. Three types of panels are analyzed, i.e., solid panels, hollow core panels and modified hollow core panels formed of a lightweight mortar pre-panel enveloped by a thin layer of grout. The panels are reinforced with a mesh steel or fiberglass fabric. The mechanical behavior of panels is determined from bending tests or compression tests under static loading. The use of mortars with expanded vermiculite as lightweight aggregate decreases the flexural strength of panels, but increases their thermal insulation by up to 10%. The use of fiberglass fabric prevents sudden failure of the modified hollow core panels. The main finding of this study is the technical feasibility of lightweight panels made of pre-cast panel mortar and expanded vermiculite reinforced with fiberglass fabric.; Programa de Apoio à Publicações Periódicas Científicas (PROAPUPEC) da UFG; O objetivo deste trabalho é determinar o comportamento mecânico de painéis pré-moldados confeccionados com argamassa contendo apenas Vermiculita Expandida.

v. 45, n. 3, p. 340-347, jul./set. 2015.; The intensive and uninterrupted tomato cultivation has favored the establishment of several diseases that affect fruit yield and quality. Genetic resistance is the best method to control the disease called ‘vira-cabeça’ (caused by distinct species of the genus Tospovirus), being Sw-5 the first resistance gene effectively identified to control it in tomato plants. This study aimed at identifying new potential sources of tospovirus resistance in wild Solanum (Lycopersicon) species, as well as performing phylogenetic analysis related to the evolutionary characteristics of the Sw-5b gene, in accessions of wild tomato species. These analyses showed that the different tomato species belong to distinct evolutionary groups. Most of the accessions with wide-spectrum resistance to Tospovirus species correspond to allelic variants closely related to the original Sw-5b gene copy. However, resistant accessions of S. chilense and S. habrochaites are located in distinct phylogenetic groups, meaning that they may represent promising sources of new genes/alleles, providing wide resistance to tospovirus.; Programa de Apoio à Publicações Periódicas Científicas (PROAPUPEC) da UFG;CNPq; CAPES; O cultivo ininterrupto e intensivo de tomateiro tem favorecido o estabelecimento de diversas doenças que afetam a produção e a qualidade dos frutos.

v. 45, n. 3, p. 356-363, jul./set. 2015.; Vascular wilting in tomato plants constitutes an important group of diseases incited by soil inhabiting pathogens, especially Fusarium oxysporum f. sp. lycopersici, that causes significant production losses. The introgression of genes that express specific resistance is considered the main control method, however, due to the rapid emergence of races that suppress resistance, biocontrol has been presented as an option to be integrated with genetic control methods. This study aimed at evaluating the ability of rhizobacteria isolates, especially from the Bacillus genus, as biological control agents of Fusarium wilt in tomato plants. The laboratory assay was carried out to verify the ability of the isolates in acting as inhibitors of mycelial growth, besides detecting the genes involved in the expression of polypeptides with antimicrobial action. In the greenhouse, the assay comprised of microbiolized seeds and addition of a suspension of propagules of each rhizobacteria to the soil at the moment of transplanting the tomato seedlings. All the rhizobateria isolates showed variable control levels of the pathogen in vitro. The UFG-07 and UFG-10 isolates, with high similarity with Bacillus subtilis and Bacillus circulans...

v. 35, n. 3, p. 397-416, set./dez. 2015.; Santiago de Compostela, the capital of the Autonomous Community of Galicia, is one of the main tourist centers of Spain. It attracts millions of visitor every year because of its cultural and architectonic assets. The religious heritage, in particular, leads thousands of pilgrims to walk the so-called Way of St. James. As a result, the city of Santiago de Compostela has developed a notable tourism infrastructure. This paper precisely aims to analyze both tourism supply and demand in Santiago. It was based on the use of cartographic methods suitable for representing qualitative data, such as typologies of attractions and existing tourist facilities; as well as quantitative data, like the number of visitors and offers of accommodations. Research results show that the cartographic representation of tourist information allows aggregating an extremely useful geographic variable to planning and spatial planning of tourism. The comparative analysis of the geographic distribution of tourism demand and supply demonstrates the existence of preferred spaces for tourism, plus a strong seasonality, which represent a challenge to government actions and policies. On the other hand, the maps also reveal problems related to the spatial variability of certain types of information. For instance...

v. 18, n. 2, p. 22-35, jul./dez. 2015.; This study aims to understand how the spiritist discourse has become political and socially possible, especially in Brazil, by establishing confrontations and accessions with other knowledge coming from the field of philosophy, science and Christianity, thus gaining legitimacy. It is argued that spiritism can be understood as part of a network of forces that conditioned the dialogue between religion and discursive values of modernity. The theoretical approach and analytical devices are based on Thompson, Bakhtin and Foucault, and it is adopted as a corpus of spiritualism founding texts written by Allan Kardec, The results show that spiritist dialogism is built in a intertextual and discursivelyway, revealing a redefinition of some Greek philosophical thesis, Christian ethics and positivism. It assumes that there is an attempt to associate the "know thyself " (gnôthi seautón) with the “self care” (epiméleia heautoû), based on the assumption of " rational faith " and " spiritist science ".; Este estudio tiene como objetivo comprender cómo el discurso espírita se há convertido en política y socialmente posible, especialmente en Brasil, para establecer confrontaciones y membresías con otros conocimientos que surgen desde el campo de la filosofía...

v. 18, n. 2, p. 145-162, jul./dez. 2015.; From the representation of the city of Palmelo (GO) as “spiritualist city”, to question what extent the sociological notion the “city” is compatible with the link to a religious cultural identity? The question-problem takes the theoretical par Weberian society / community as a starting point for understanding the concept of city in process complexity and functional differentiation in tension with advances in questioning of Stuart Hall (2006) on cultural identity decentralizes the modern subject – it’s the same subjectpresupposed in the classical theory of the community, generating inferences so also in this last concept. Under this questioning, the specific objective of this work is to take religion theory notes as symbolic form, questioning possible limitations on Weber (2000), Cassirer (1992) and Bourdieu (2009), before conflicting notions of identity and community.; A partir de la representación de la ciudad de Palmelo (GO) como “la ciudad espiritualista”, cuestionamos ¿En qué medida la noción sociológica de la ciudad es compatible con el enlace a una identidad cultural religiosa? La pregunta-problema toma el par teórico weberiano sociedad / comunidad como punto de partida para entender el concepto de ciudad en la complejidad del proceso y la diferenciación funcional en tensión con los avances en el cuestionamiento de Stuart Hall (2006) sobre la identidad cultural qué descentraliza el sujeto moderno - es el mismo supuesto chico en la teoría clásica de la comunidad...

v. 18, n. 02, p. 163-179, jul./dez. 2015.; This article's initial proposal to perform a conceptual survey of citizenship, as well as an analysis of the evolution of Information and Communication Technologies (ICTs) and their potential uses with regard to optimize the process of appropriation of this citizenship by living individuals in the polis. Through a survey led by the literature review method has teamed up classic and modern concepts on the subject in question, plotting them in today's reality in which technology has a strong presence in the processes of meaning and redefinition of citizen's status and citizenship itself , theme of this research. Possession of concepts and contextual analysis of the ICT - Citizenship is reached, in this study, a depression of perspective between them, where the anachronism is present and requires measures to be able to correct such asynchronicity. Finally this text reinforces the need to rethink the current educational process in this society, so that individuals are prepared to master the technology in search of reaching the citizen condition.; La propuesta inicial de este artículo para realizar un estudio conceptual de la ciudadanía, así como un análisis de la evolución de las Tecnologías de la Información y la Comunicación (TIC) y sus usos potenciales en cuanto a optimizar el proceso de apropiación de esta ciudadanía por las personas que viven en la polis.
