Avaliação de duas variedades de Passiflora edulis sobre as respostas comportamentais de camundongos e um possível mecanismo de ação

The medicinal plants constitute a rich source of biologically active compounds used for the treatment of many psychiatric disorders, such as anxiety disorders and depression. Generalized anxiety disorder has increased significantly, being the second most prevalent disorder in care facilities to public health. Depression is considered a chronic and common psychiatric disorder that affects 350 million people of all ages around the world. In this context, the pharmacological intervention conduits have been employed, effective, although leave to be desired when observed adverse effects. The genus Passiflora is commonly commercially known by its fruit, but is also widely used in traditional Brazilian medicine. Passiflora edulis displays considerable morphological variability. This plant produces two types of fruit: Purple (Passiflora edulis Sims fo. edulis) and yellow (Passiflora edulis fo. flavicarpa Degener). This study investigated the central effects of aqueous extract of the leaves of the two varieties of the species Passiflora edulis in tests used to assess behavior related to anxiety and depression, as well as investigating the potential effect of the antidepressant-like fractions of edulis fo. edulis and neuropharmacological mechanisms responsible for this action. To conduct this study used male Swiss mice (2 months old, weighing 30-35 g). The animals received the aqueous extract of the leaves of the two species of Passiflora: edulis fo. edulis (100, 300, 1000 mg / kg) and fractions ethyl acetate, butanol and aqueous waste (25, 50, 75, 100 mg / kg) and edulis fo. flavicarpa (30, 100, 300, 1000 mg / kg) or saline by gavage 60 minutes prior to the maze tests at high cross the open field test, test forced swim test and sedation induced by thiopental. To investigate the mechanism of action of the activity of antidepressant type of fractions the following drugs were used: PCPA (inhibitor of 5-HT synthesis) AMPT (inhibitor of catecholamine synthesis), DSP-4 (noradrenergic neurotoxin) and Sulpiride (antagonist selective dopamine D2 receptor). They were used as a standard positive control, fluoxetine and nortriptyline. The results of the phytochemical profile show very different characteristics to the aqueous extract of the varieties of Passiflora edulis "flavicarpa" and "edulis". The aqueous extracts of both varieties of Passiflora edulis share anxiolytic activity type (edulis fo. edulis 300 mg/kg; edulis fo. flavicarpa 300 and 1000 mg/kg) and antidepressant (edulis fo. edulis 300 mg/kg; edulis fo flavicarpa 1000 mg/kg), while the effect hipolocomotor/sedative was only seen for edulis fo. edulis (1000 mg/kg). Both fractions ethyl acetate, butanol aqueous extract edulis fo. edulis showed activity type antidepressant at a dose of 50 mg/kg in the forced swim test. The data suggest that the effect of antidepressant-like fractions edulis fo. edulis involves catecholaminergic and serotonergic neurotransmission, particularly dopaminergic, there is seen that pre-treatment DSP-4 is not affected antidepressant action of fractions as was dependent activation of dopamine D2 receptors.

Uma proposta de indicadores para o acompanhamento de alunos em projetos de desenvolvimento colaborativo de software com foco no desenvolvimento de habilidades transversais

Soft skills and teamwork practices were identi ed as the main de ciencies of recent graduates in computer courses. This issue led to a realization of a qualitative research aimed at investigating the challenges faced by professors of those courses in conducting, monitoring and assessing collaborative software development projects. Di erent challenges were reported by teachers, including di culties in the assessment of students both in the collective and individual levels. In this context, a quantitative research was conducted with the aim to map soft skill of students to a set of indicators that can be extracted from software repositories using data mining techniques. These indicators are aimed at measuring soft skills, such as teamwork, leadership, problem solving and the pace of communication. Then, a peer assessment approach was applied in a collaborative software development course of the software engineering major at the Federal University of Rio Grande do Norte (UFRN). This research presents a correlation study between the students' soft skills scores and indicators based on mining software repositories. This study contributes: (i) in the presentation of professors' perception of the di culties and opportunities for improving management and monitoring practices in collaborative software development projects; (ii) in investigating relationships between soft skills and activities performed by students using software repositories; (iii) in encouraging the development of soft skills and the use of software repositories among software engineering students; (iv) in contributing to the state of the art of three important areas of software engineering, namely software engineering education, educational data mining and human aspects of software engineering.

Crescimento urbano e seus impactos no sistema de drenagem de uma bacia em Natal/RN

The uncontrolled growth of most Brazilian cities is not accompanied by the development of urban infrastructure. With increasing soil sealing, runoff and decreased infiltration volume, impacts on water resources and on population of the areas affected by urban growth are inevitable. This study aims to evaluate the use and occupation of a watershed and analyze the drainage system in order to control the impact using tools to integrate urban development with the drainage of rainwater in an important watershed in the Natal City, Rio Grande do Norte State. The study involved the characterization of the basin XII.4 on the land use and occupation, for the years 2005 and 2014. With the application of SWMM model was possible to analyze the impacts caused by the urbanization process in the existing drainage system, showing the two years analyzed have their areas very close to percentage saturation of impervious areas. Although the region is still predominantly single family residential, suffers increasing verticalization of mainly commercial buildings. The drainage system is inefficient for the area's needs by the year 2005. The drainage system was also tested for four variations of land use by developing scenarios. Scenario 1 is related to the year 2014, considered current. Scenario 2 was adopted the maximum rate of 80% for land use, allowed for the Natal City. Scenario 3 gives the critical condition of land use, with the area 100% impervious. Scenario 4 is applied to the existence of LID (Low Impact Device). The scenarios analysis showed that all indicate deficiency at some point of the drainage system as a result of the high degree of occupation of the area that generate higher flows than the initial drainage system capacity. With the study it became clear that the adoption of non-structural tools are effective in reducing flooding and improving the drainage system capacity.

Plano de desenvolvimento sustentável e articulação de políticas públicas: o controle de políticas ambientais pelo poder judiciário

The right to the preservation of a healthy environment is perceived as a Fundamental Right, inserted in the National Constitution and referring to present and future generations. The preservation of the environment is directly connected to the right to Health and Human Dignity and, therefore, must be treated as a personal right, unavailable, claiming for a positive response from the Brazilian State, through the development of related public policies, control of potentially harmful economic activities, with special focus on the principles of precaution and solidarity. The Brazilian judiciary must thus be attentive to the guardianship of the Fundamental Right. The judiciary control over the execution of public policies is based on obeying the principle of the separation, independence and harmony between the Powers, however it should never deviate from the constitutional obligation of caring for the effectivation of the rights and guarantees within the Magna Carta. In the balance between the principle of human dignity, from which springs the right to a healthy environment and the principle of separation of powers, the former should prevail, maintaining the latter to a core minimum.

Estudo da usabilidade do portal do aluno do SIGAA Mobile Android da UFRN: identificando diretrizes de interface a serem utilizadas como recomendações no processo de desenvolvimento das funcionalidades deste sistema

Avaliação de usabilidade é um processo importante durante o desenvolvimento de um software, seja ele para um sistema web ou mobile. No caso de um sistema mobile, o custo é bastante oneroso, tanto no que se refere à mão de obra especializada, como de recursos tecnológicos utilizados, tornando essa avaliação de usabilidade ainda mais importante. Além disso, as versões webdos sistemas SIG da UFRN já estão consolidadas e com uma grande aceitação, fazendo com que suas versões mobile tenham, ainda mais, a preocupação de lançar um produto de boa qualidade para manter essa credibilidade dos sistemas SIG , tanto na UFRN, como nas demais instituições que utilizam esses sistemas. Com este trabalho, buscou-se identificar algumas diretrizes de interface que possam ser utilizadas no processo de desenvolvimento dos sistemas SIG Mobile, mais especificamente o SIGAA Mobile, de modo a facilitar o desenvolvimento de novas funcionalidades voltadas para estes sistemas. Para isso, foi realizada uma avaliação de usabilidade no Portal do Aluno do SIGAA Mobile Android, tomando como base padrões de interface já existentes na literatura. Posteriormente, foi aplicado um questionário com os usuários do sistema para coletar as opiniões e sugestões dos mesmos. De posse de todos esses dados coletados, foi possível definir algumas diretrizes de interface a serem seguidas como recomendações no processo de desenvolvimento dos sistemas SIG Mobile.

A pedagogia de projetos e o ensino de música na educação básica da cidade de Natal/RN

This research aims to investigate the use of Project based learning as a method for teaching music in Elementary Schools located in Natal, RN. Its main objective is to analyze how this method is used during the classes of music at school context and which are its implications to the process of music learning acquirement. The specific objectives comprise: gathering the music teachers in preschool that work with project based learning as a method for their classes; identifying how the theory meets their practice; and analyzing how project based learning contributes to the learning process of music within schools. The main scholars adopted as theoretical reference were Boutinet (2002), Hernández (1998; 200), Antunes (2001), Cavalcante (2009), from Education area; and Penna (2008), Fonterrada (2008), Queiroz (2012), regarding Musical Education. Such choice was made in views of identifying the relationship and how project based pedagogy associates to the current Brazil school curriculum. For data collection, mixed methodological strategies were used, of qualitative and quantitative approaches that are complementary for better meeting the research needs. By applying a questionnaire, it was sought to identify the music schools and teachers who reported working with project based learning. Based on these results were selected two schools, one private school and one public school to perform a participant observation in two groups following the development of music classes based on project based learning, and the information were recorded in a diary of audio and video recordings. The results of this work show that the Project Education is a methodology frequently used by music teachers from Natal/ RN contributing to the integration of content and subjects and engages students in activities awakening interest and contributing to the development of music education at school. However, it was identified that many of the conceptions of the teachers about projects are confused by ambiguities from the use of the term in different areas and in various theoretical perspectives as well as the lack of publications that address the music education through the project based learning. It is hoped that this study provides discussions and research about the project based learning applied to music education in elementary school.

Desenvolvimento profissional de futuros professores: travessias que se entrecruzam em contextos formativos

This study aimed to understand how the educational context contributes to the professional development of future teachers on introduction to teaching practice. To this end, we seek to characterize what the learning and the difficulties experienced in training contexts by future teachers, as well as the intrinsic elements to the training contexts that enable professional development. The investigated contexts were the Institutional Program Initiation Grant to Teaching (Programa Institucional de Bolsa de Iniciação à Docência – PIBID), specifically the sub-projects of Chemistry and Physics of the Federal University of Rio Grande do Norte (Universidade Federal do Rio Grande do Norte – UFRN) and Masters in Teaching of Physics and Chemistry of the University of Lisbon (MEFQ ). In both contexts, the future teachers are in contact with the school in a systematic way. The methodology used in our study is rooted in qualitative research with interpretative guidance and the design in the study of multiple cases with instrumental purpose. Participated in this study as the main subject, 40 future teachers PIBID of Physics, 24 PIBID future teachers of Chemistry and 5 future Master Teachers in Teaching Chemistry and Physics. As supporting subjects, participated in 3 PIBID Area Coordinators, the teacher of Introduction to Professional Practice of MEFQ, and 8 teachers who teach chemistry and / or physics in public schools. Multiple data collection tools were used: naturalistic observation, descriptive questionnaire, individual interviews, focus groups, reading of written records and official documents. In analyzing the data, we used the method of questioning and constant comparison. The results showed that the main learning of future teachers are related to the strategy employed in class, the change in the understanding of the role of teacher and student in the classroom, the construction of the professional profile and the development of collaborative practices. The main difficulties were related to the development of activities, the management of time and group, the dynamics of the classroom and the material conditions of work. The characteristics inherent in training contexts investigated for professional development are: the practice itself of the research, the collaboration, the focused reflection on practice, focus on student learning and the improving public schools. From the results, it is evidenced that the training contexts centered at school have the capability to resize the practice based on the analysis of actions, in a collaborative work as well as create opportunities for awareness of the concepts, the acting and the way to understand the profession. It is needed for effective mediation trainers, so that future teachers undertake their own practice and, therefore, they can build teaching strategies that promote learning which, in addition to increase the quality of education, favor the professional development throughout life.

DESENVOLVIMENTO DO TEATRO MUSICAL BRASILEIRO À LUZ DA NOTORIEDADE MIDIÁTICA DAS ADAPTAÇÕES E DOS ARTISTAS

O trabalho tem a proposta de analisar os desdobramentos do teatro musical brasileiro desde a primeira encenação em território nacional de adaptações de espetáculos do Teatro de Revista, gênero originário da França, até as superproduções musicais realizadas nos últimos 16 anos de adaptações de espetáculos americanos. O panorama histórico e analítico será estudado, com ênfase no teatro musical que se utiliza de elementos midiatizados para estar inserido em uma sociedade em que a produção cultural é vista como internacionalizada e mercantilizada. Como forma de marketing, os produtores utilizam-se da notoriedade midiática presente em formatos estrangeiros já consagrados, adaptações renomadas e bem aceitas pelo público, além da fama de celebridades que são escaladas para os musicais. Tudo para a conquista de um patrocinador que, por sua vez, acaba fazendo exigências que interferem de maneira decisiva na montagem dos espetáculos. Em meio a um processo onde são tantos os direcionamentos pré-estabelecidos por patrocinadores, onde se encontra o genuíno teatro musical brasileiro? A pesquisa abrange o ineditismo da presença de temáticas nacionais em formatos estrangeiros e agrega o conjunto de fatores que possibilitam que um roteiro de musical saia do papel e adentre os palcos, tais como as políticas públicas de incentivos fiscais; a ligação de empresas patrocinadoras e suas marcas a musicais; o fato de que, mesmo as produções sendo pagas por dinheiro público, possuírem ingressos que não são a preços populares. Para auxiliar nas conjecturas a serem formadas, será utilizada uma metodologia histórico-descritiva com foco na relação do tema com elementos notórios na mídia, como os artistas e obras a serem adaptadas no palco.

A relação entre os jovens e o corpo em Natal

O presente estudo resulta de uma pesquisa em desenvolvimento na Universidade Federal do Rio Grande do Norte que busca estabelecer relações entre o papel do corpo, em um contexto midiático, na construção e constituição da subjetividade de jovens em Natal, capital norte-riograndense. Expressões dessa subjetividade indicam que o corpo, a mídia eletrônica e a Internet são referências importantes que permitem perceber traços ao mesmo tempo singulares e universais de uma cultura juvenil, que é complexa e ambivalente por natureza

Modelo institucional do processo de estruturação de empresas de desenvolvimento de software: um estudo de múltiplos casos

Some authors have shown the need of understanding the technological structuring process in contemporary firms. From this perspective, the software industry is a very important element because it provides products and services directly to many organizations from many fields. In this case, the Brazilian software industry has some peculiarities that distinguish it from other industries located in developed countries, which makes its understanding even more relevant. There is evidence that local firms take different strategies and structural configurations to enter into a market naturally dominated by large multinational firms. Therefore, this study aims to understand not only the structural configurations assumed by domestic firms but also the dynamic and the process that lead to these different configurations. To do so, this PhD dissertation investigates the institutional environment, its entities and the isomorphic movements, by employing an exploratory, descriptive and explanatory multiple cases study. Eight software development companies from the Recife's information technology Cluster were visited. Also, a form was applied and an interview with one of the main firm s professional was conducted. Although the study is predominantly qualitative, part of the data was analyzed through charts and graphs, providing a companies and environment overview that was very useful to analysis done through the interviews interpretation. As a result, it was realized that companies are structured around hybrids business models from two ideal types of software development companies, which are: software factory and technology-based company. Regarding the development process, it was found that there is a balanced distribution between the traditional and agile development paradigm. Among the traditional methodologies, the Rational Unified Process (RUP) is predominant. The Scrum is the most used methodology among the organizations based on the Agile Manifesto's principles. Regarding the structuring process, each institutional entity acts in such way that generates different isomorphic pressure. Emphasis was given to entities such as customers, research agencies, clusters, market-leading businesses, public universities, incubators, software industry organizations, technology vendors, development tool suppliers and manager s school and background because they relate themselves in a close way with the software firms. About this relationship, a dual and bilateral influence was found. Finally, the structuring level of the organizational field has been also identified as low, which gives a chance to organizational actors of acting independently
