Interação entre professora e alunos em salas de aula com proposta pedagógica de educação inclusiva

Correntes teóricas presentes na literatura científica têm demonstrado a importância das relações interpessoais para o processo de construção do conhecimento. É no contexto da interação professor e aluno que se configura a relação entre as necessidades educacionais dos alunos e as respostas pedagógicas a elas disponibilizadas, o que envolve o domínio do conhecimento pelo professor, sua capacitação técnico-científica, a competência de ensinar pesquisando, as características sócio-culturais e o perfil psicológico dos atores sociais envolvidos- professor e aluno. Buscando melhor compreender este universo, elaborou-se este estudo que teve como objetivo descrever as interações ocorridas entre uma professora, e seus alunos, em classes em que se propunha adotar uma prática pedagógica inclusiva. Os dados foram coletados em 2 salas de aula, em escola estadual de Ensino Fundamental, no município de Bauru. O processo de coleta de dados se deu através do registro da realidade de sala de aula em vídeo tape. Optou-se por este método, por permitir a recuperação posterior dos dados. A coleta se deu no transcorrer do 1º semestre do ano letivo de 2001. A análise fundamentou-se em sistema prévio de categorias, e tratou os dados quantitativa e qualitativamente. Os resultados demonstraram peculiaridades e diferenças nas interações da professora com os seus alunos, em função da presença ou ausência da deficiência. Indicaram, também, que a interação vem demonstrando avanços na prática educacional, no que diz respeito à atenção pedagógica, da professora, ao aluno com deficiência.

Custos e viabilidade econômica da produção de lambari-do-rabo amarelo em Monte Castelo/SP: um estudo de caso

The aim of this study was to analyze the cost of production and economic viability of production of Lambari in Monte Castelo/SP, with the primary market for the live-bait for sport fishing of carnivorous fish. To calculate the operating cost structure was used the model proposed by the Instituto de Economia Agricola from São Paulo/Brazil. In analyzing the economic viability of investment, we determined the Internal Rate of Return (IRR) and Pay Back Period. It was noted that the inputs represented approximately 74.0% of the EOC (Effective Operating Cost). In the rentability analysis (short term), there was an operating profit of R$ 3,133.45 for a cycle, with a profitability of 18.65% for four months of production, a cost price of R$ 13.02 kg(-1). For viability of the activity (long term), the results were attractive to recovery capital from the 3(rd) year (Pay Back), with an IRR of 25.68% and 89.0% return on the producer in 5 years (BCR - benefit cost ratio). The study of costs and economic viability analysis reinforce the importance of rational management in the productive system and the importance of planning and managing the profitability of the activity.

Composição da artropodofauna entomófoga associada a diferentes genótipos de sorgo granífero no cerrado do Sudeste do Brasil

Espécies de artrópodos entomófagos foram coletadas e identificadas nos genótipos sorgo AF-28, IAC-83/75-5-1-6, TX-2536, BR-300, IPA-201 e SAR, no Município de Selvíria, MS. Foram conduzidos três experimentos em campo, com os genótipos sendo semeados em 03/1988, 10/1988 e 02/1989, respectivamente. Para contagem dos artrópodos entomófagos, no início do florescimento foram marcadas 560 panículas por genótipo. Após esse momento, diariamente e durante 14 dias seguidos, foram coletadas 40 panículas por genótipo (10 por parcela). Nas coletas foram utilizados sacos plásticos com 10 litros de capacidade para envolver as panículas e capturar os artrópodos presentes. As panículas coletadas foram levadas para o Laboratório de Entomologia da Faculdade de Engenharia/UNESP, Campus de Ilha Solteira, SP, para separação, contagem e identificação dos artrópodos. Nas panículas provenientes da semeadura da seca coletou-se, em média, maior número de artrópodos entomófagos em relação à semeadura das águas. Dos artrópodos entomófagos coletados, as aranhas apresentaram maior número de espécies e, desses, a tecelã Alpaida veniliae (Keys.), a aranha corredora noturna Cheiracanthium inclusum (Blackwall), e a caçadora de emboscada, Misumenops pallidus (Keys.), foram as mais abundantes. O genótipo de sorgo IPA-201 comportou-se como o mais atrativo ao percevejo Orius sp. e à tesourinha Doru lineare (Eschs.), enquanto que o IAC-83/75-5-1-6 foi medianamente atrativo a D. lineare. As aranhas foram coletadas em maior número nos genótipos BR-300 e SART.

Uma abordagem anotativa para gerência de variabilidade em linhas de processos de software: concepção, implementação e avaliação

Nowadays, the importance of using software processes is already consolidated and is considered fundamental to the success of software development projects. Large and medium software projects demand the definition and continuous improvement of software processes in order to promote the productive development of high-quality software. Customizing and evolving existing software processes to address the variety of scenarios, technologies, culture and scale is a recurrent challenge required by the software industry. It involves the adaptation of software process models for the reality of their projects. Besides, it must also promote the reuse of past experiences in the definition and development of software processes for the new projects. The adequate management and execution of software processes can bring a better quality and productivity to the produced software systems. This work aimed to explore the use and adaptation of consolidated software product lines techniques to promote the management of the variabilities of software process families. In order to achieve this aim: (i) a systematic literature review is conducted to identify and characterize variability management approaches for software processes; (ii) an annotative approach for the variability management of software process lines is proposed and developed; and finally (iii) empirical studies and a controlled experiment assess and compare the proposed annotative approach against a compositional one. One study a comparative qualitative study analyzed the annotative and compositional approaches from different perspectives, such as: modularity, traceability, error detection, granularity, uniformity, adoption, and systematic variability management. Another study a comparative quantitative study has considered internal attributes of the specification of software process lines, such as modularity, size and complexity. Finally, the last study a controlled experiment evaluated the effort to use and the understandability of the investigated approaches when modeling and evolving specifications of software process lines. The studies bring evidences of several benefits of the annotative approach, and the potential of integration with the compositional approach, to assist the variability management of software process lines

Avaliação sistemática de abordagens de derivação de produto

Product derivation tools are responsible for automating the development process of software product lines. The configuration knowledge, which is responsible for mapping the problem space to the solution space, plays a fundamental role on product derivation approaches. Each product derivation approach adopts different strategies and techniques to manage the existing variabilities in code assets. There is a lack of empirical studies to analyze these different approaches. This dissertation has the aim of comparing systematically automatic product derivation approaches through of the development of two different empirical studies. The studies are analyzed under two perspectives: (i) qualitative that analyzes the characteristics of approaches using specific criteria; and (ii) quantitative that quantifies specific properties of product derivation artifacts produced for the different approaches. A set of criteria and metrics are also being proposed with the aim of providing support to the qualitative and quantitative analysis. Two software product lines from the web and mobile application domains are targets of our study

Uma abordagem sistemática para implementação, gerenciamento e customização de testes de linhas de produto de software

Through the adoption of the software product line (SPL) approach, several benefits are achieved when compared to the conventional development processes that are based on creating a single software system at a time. The process of developing a SPL differs from traditional software construction, since it has two essential phases: the domain engineering - when common and variables elements of the SPL are defined and implemented; and the application engineering - when one or more applications (specific products) are derived from the reuse of artifacts created in the domain engineering. The test activity is also fundamental and aims to detect defects in the artifacts produced in SPL development. However, the characteristics of an SPL bring new challenges to this activity that must be considered. Several approaches have been recently proposed for the testing process of product lines, but they have been shown limited and have only provided general guidelines. In addition, there is also a lack of tools to support the variability management and customization of automated case tests for SPLs. In this context, this dissertation has the goal of proposing a systematic approach to software product line testing. The approach offers: (i) automated SPL test strategies to be applied in the domain and application engineering, (ii) explicit guidelines to support the implementation and reuse of automated test cases at the unit, integration and system levels in domain and application engineering; and (iii) tooling support for automating the variability management and customization of test cases. The approach is evaluated through its application in a software product line for web systems. The results of this work have shown that the proposed approach can help the developers to deal with the challenges imposed by the characteristics of SPLs during the testing process

Uso de modelos i* para enriquecer requisitos em métodos ágeis

The activity of requirements engineering is seen in agile methods as bureaucratic activity making the process less agile. However, the lack of documentation in agile development environment is identified as one of the main challenges of the methodology. Thus, it is observed that there is a contradiction between what agile methodology claims and the result, which occurs in the real environment. For example, in agile methods the user stories are widely used to describe requirements. However, this way of describing requirements is still not enough, because the user stories is an artifact too narrow to represent and detail the requirements. The activities of verifying issues like software context and dependencies between stories are also limited with the use of only this artifact. In the context of requirements engineering there are goal oriented approaches that bring benefits to the requirements documentation, including, completeness of requirements, analysis of alternatives and support to the rationalization of requirements. Among these approaches, it excels the i * modeling technique that provides a graphical view of the actors involved in the system and their dependencies. This work is in the context of proposing an additional resource that aims to reduce this lack of existing documentation in agile methods. Therefore, the objective of this work is to provide a graphical view of the software requirements and their relationships through i * models, thus enriching the requirements in agile methods. In order to do so, we propose a set of heuristics to perform the mapping of the requirements presented as user stories in i * models. These models can be used as a form of documentation in agile environment, because by mapping to i * models, the requirements will be viewed more broadly and with their proper relationships according to the business environment that they will meet

Avaliação da contribuição de desenvolvedores para projetos de software usando mineração de repositórios de software e mineração de processos

Software Repository Mining (MSR) is a research area that analyses software repositories in order to derive relevant information for the research and practice of software engineering. The main goal of repository mining is to extract static information from repositories (e.g. code repository or change requisition system) into valuable information providing a way to support the decision making of software projects. On the other hand, another research area called Process Mining (PM) aims to find the characteristics of the underlying process of business organizations, supporting the process improvement and documentation. Recent works have been doing several analyses through MSR and PM techniques: (i) to investigate the evolution of software projects; (ii) to understand the real underlying process of a project; and (iii) create defect prediction models. However, few research works have been focusing on analyzing the contributions of software developers by means of MSR and PM techniques. In this context, this dissertation proposes the development of two empirical studies of assessment of the contribution of software developers to an open-source and a commercial project using those techniques. The contributions of developers are assessed through three different perspectives: (i) buggy commits; (ii) the size of commits; and (iii) the most important bugs. For the opensource project 12.827 commits and 8.410 bugs have been analyzed while 4.663 commits and 1.898 bugs have been analyzed for the commercial project. Our results indicate that, for the open source project, the developers classified as core developers have contributed with more buggy commits (although they have contributed with the majority of commits), more code to the project (commit size) and more important bugs solved while the results could not indicate differences with statistical significance between developer groups for the commercial project

Sistema de apoio à interatividade em revisões sistemáticas em engenharia de software

A colaboração na pesquisa é uma das tarefas centrais da área acadêmica. Atualmente, muitos pesquisadores estão utilizando meios modernos de troca de arquivos digitais através de ferramentas assíncronas e também com o uso de ferramentas mais sofisticadas, do tipo síncronas. Juntamente com o fato da crescente quantidade de artigos sendo gerados, mais complexos, diversificados e aumentando de forma desorganizada, o que trás ao pesquisador uma tarefa difícil para organizá-los de forma a se extrair o melhor conteúdo destes, isto ocorre porque uma subárea da Engenharia de Software (ES) ainda é bastante mal aproveitada, a Engenharia de Software Experimental (ESE). Utilizando-se de um dos tipos de experimentos que a ESE oferece, as revisões sistemáticas entram como uma solução bastante robusta, na qual o pesquisador pode identificar o conhecimento existente em uma área e planejar devidamente sua pesquisa, evitando a repetição de erros em pesquisas já efetivadas por outros pesquisadores no passado. Contudo, estas duas abordagens, a colaboração virtual de pesquisadores e a utilização de revisões sistemáticas, contem problemas: na primeira, sistemas colaborativos são geralmente difíceis de configurar e usar; na segunda, apesar da robustez da metodologia de revisões sistemáticas, ainda se torna necessário uma rigorosa revisão na literatura para se conseguir um resultado satisfatório. Assim, com o foco de unir estas duas abordagens, este trabalho propõe uma maneira de produzir revisões sistemáticas de forma organizada e com a possibilidade de interação entre usuários, com o desenvolvimento de um sistema interativo, no qual as revisões sistemáticas possam ser geradas por usuários em colaboração com outros e também ser avaliadas seguindo a orientação de um profissional da área, tornando o seu conteúdo mais consistente e de melhor qualidade. O sistema não possui níveis de acesso, ou seja, qualquer pessoa pode se cadastrar e usufruir de seus recursos, seja na área acadêmica ou mesmo na área profissional

POPT: uma abordagem de ensino de programação orientada a problema e testes

There is a growing interest of the Computer Science education community for including testing concepts on introductory programming courses. Aiming at contributing to this issue, we introduce POPT, a Problem-Oriented Programming and Testing approach for Introductory Programming Courses. POPT main goal is to improve the traditional method of teaching introductory programming that concentrates mainly on implementation and neglects testing. POPT extends POP (Problem Oriented Programing) methodology proposed on the PhD Thesis of Andrea Mendonça (UFCG). In both methodologies POPT and POP, students skills in dealing with ill-defined problems must be developed since the first programming courses. In POPT however, students are stimulated to clarify ill-defined problem specifications, guided by de definition of test cases (in a table-like manner). This paper presents POPT, and TestBoot a tool developed to support the methodology. In order to evaluate the approach a case study and a controlled experiment (which adopted the Latin Square design) were performed. In an Introductory Programming course of Computer Science and Software Engineering Graduation Programs at the Federal University of Rio Grande do Norte, Brazil. The study results have shown that, when compared to a Blind Testing approach, POPT stimulates the implementation of programs of better external quality the first program version submitted by POPT students passed in twice the number of test cases (professor-defined ones) when compared to non-POPT students. Moreover, POPT students submitted fewer program versions and spent more time to submit the first version to the automatic evaluation system, which lead us to think that POPT students are stimulated to think better about the solution they are implementing. The controlled experiment confirmed the influence of the proposed methodology on the quality of the code developed by POPT students

Entendendo as interações entre povos pesqueiros, manguezal e área protegida: RDS estadual Ponta do Tubarão (RN, Brasil)

The mangrove ecosystem has a great importance to maintaining marine biodiversity, and to the livelihoods of communities living around it. Despite its importance, many mangrove areas have been extensively cleared and converted to other uses. There are few places where communities can retain their traditional uses of mangrove. A good example of conservation of traditional costumes are the fishing communities of the Sustainable Development Reserve (Reserva de Desenvolvimento Sustentável RDS) Ponta do Tubarão. The creation of the reserve came from the own population, and the devastation of a mangrove area, which would be destined for activity shrimp, was one of the reasons that led the population to ask authorities the establishment of a legally protected area. Thus, this study aimed to investigate the environmental perception of the fishing communities of RDS Ponta do Tubarão with respect to the mangroves in a biological, ecological and social perspective as well as evaluate the influence of the reserve in the mangrove conservation and quality of life. To meet objectives of this study was required the appropriation of some method and approaches of ethnosciences and environmental perception. Data were collected through direct observation, and semi-structured interviews. Through content analysis found that the population has a strong dependence on the mangrove ecosystem, as well as provides a good ecological knowledge of ecosystem functions. It was also found that the reservation has a good performance in the conservation of the mangroves; however, need to outline strategies to conciliate both the biological and cultural conservation.

Associação entre acrocórdons e resistência à insulina

FUNDAMENTOS: Acrocórdons são lesões dermatológicas comuns na população e estão associados ao diabetes mellitus, à obesidade, à resistência insulínica e à aterosclerose. A identificação precoce de pacientes com resistência insulínica pode ter papel preventivo primário. OBJETIVO: Avaliar a associação entre presença de acrocórdons cervicais ou axilares e resistência insulínica. MÉTODOS: Estudo transversal com pacientes dermatológicos adultos atendidos em hospital universitário. Casos foram definidos como portadores de mais de cinco acrocórdons cervicais e/ou axilares. A resistência insulínica foi estimada pelo índice HOMA-IR. Resultados foram ajustados pelas demais covariáveis de risco para resistência insulínica conhecidos, a partir de regressão logística múltipla. RESULTADOS: Avaliaram-se 98 casos e 103 controles, que não diferiram entre si quanto à idade ou ao gênero. Acrocórdons se associaram diretamente aos valores de HOMA-IR (Odds Ratio = 1,4), hipertrigliceridemia e índice de massa corpórea, independentemente do ajuste por diabetes mellitus, idade, fototipo, gênero, história de diabetes mellitus familiar e relação cintura/quadril. Níveis qualitativamente elevados de HOMA-IR (> 3,8) também evidenciaram associação significativa (Índice de probabilidade = 7,5). CONCLUSÕES: Presença de múltiplos acrocórdons se associou à resistência insulínica, independentemente dos demais fatores de risco.

O território das novas economias e suas implicações socioambientais na comunidade pesqueira de Barra do Cunhaú

This dissertation aims to analyze the territory of the new economies and their social implications in the district of Barra do Cunhaú / Canguaretama. We used techniques of qualitative research (document analysis, interviews and observations in situ). It was found that the changes occurring in the territory are linked to the pressures caused by factors internal and external orders, such as the deployment and expansion of projects for development of tourism and shrimp in place, which led to the advancement of real estate speculation and intensification of the deforestation of areas of mangroves along the estuary of the river Curimataú / Cunhaú, contributing to the abandonment of fishing and agriculture for livelihood in this community, therefore, the loss of traditional knowledge applied in the conduct of this activity. It was also found that changes in the use of territory and resources threaten biodiversity and have contributed to the reduction of fish stocks of the Municipality of Canguaretama and thus bar the Cunhaú, especially the stock of crab, Uca (ucides cardatus ). The results indicated that the production in large scale in a market economy, as is the shrimp, ignores the search for balance in regional settings. Thus the environmental disturbances resulting from the shrimp and tourism have consequences for social and cultural aspects, directly affecting the livelihood of the residents of Barra do Cunhaú. Companies of shrimp and related to tourism have absorbed the fishermen who are leaving the fishing activity. However, the low level of education associated with age are factors that make them far outside the framework of employees of these companies. Therefore, it is necessary to create conditions that allow the development of the shrimp and tourism without putting at risk the sustainability of the region
