Apontamentos do movimento ambiental e desenvolvimento sustentável

Na formação do movimento ambientalista, as Conferências Internacionais realizadas desde o final da década de 1960, através do Clube de Roma, até os dias atuais, com as Conferências das Partes – COP, há uma tentativa de colocar nas agendas dos países e da humanidade um alerta demonstrando a preocupação e a necessidade de mudanças do pensar e do atuar desenvolvimentista com novas propostas que aproximem a relação sadia do homem com a natureza

Pensando a sustentabilidade: um olhar sobre a Agenda 21

Trata-se neste ensaio de uma reflexão que permite subsidiar práticas politicamente avançadas que delineiem ações emancipadas. Nas últimas décadas, a degradação ambiental tem aumentado em níveis insuportáveis, caracterizada por diferentes estágios de desenvolvimento econômico e de ação humana, levando- nos a acreditar que medidas concretas e efetivas precisam ser tomadas no sentido de articular o crescimento das condições socioeconômicas com a sustentabilidade. Um dos caminhos teórico-práticos diz respeito à implantação da Agenda 21, contemplando normas e diretrizes para implementar ações locais e regionais. Thinking over sustainability: a reflection over Agenda 21 Abstract This paper is about a reflection that allows us to subsidise policie advanced which sketch emancipated actions. In the last decades, the environmental degradation has increased to intolerable levels, characterized by different stages of economic development and human action, leading us to believe that real and effective measures have to be taken to articulate the growth of the social economic conditions with sustainabillity. One of the theoretical practical ways concerns the introduction of Agenda 21 which contemplates rules and principles to implement local and regional actions

Em busca de uma proposta metodológica para o desenvolvimento de software educativo colaborativo

Apesar da existência de metodologias para especificação de sistemas computacionaisconsolidadas na área de Computação e Informática, o caráter diferenciado do softwareeducativo vem impulsionado a investigação nesta área, em busca de uma proposta quecontemple, além dos aspectos computacionais, também os aspectos educacionais, deinterface e colaboração. O presente artigo apresenta uma proposta metodológica para odesenvolvimento de software educativo colaborativo. Este estudo considera a análisedas especificidades dos softwares educativos em relação aos de aplicação comercial eindustrial, bem como as diferentes metodologias de desenvolvimento propostas pelaárea de engenharia de software. Esta metodologia está sendo validada na construção doambiente PALCO (Portal Acessível para Linguagem Colaborativa), atualmente emdesenvolvimento pelo Grupo de Pesquisa de Tecnologias de Informação do CentroUniversitário Feevale

Relevance of the sustainability theme between of the term paper of the bachelor in Information and Communication Technologies

The present study proposes the exploration, analysis and representation of the term paper, in Portuguese language the TCCs, presented as a requirement to obtain a bachelor's degree in the Information and Communication Technologies, Federal University of Santa Catarina, Campus Araranguá. TCCs submitted to the University's repository in the period 2012 and 2015. Through the extraction of different items available in the TCCs as: teacher, keywords, abstract and year, and submission to the techniques of extraction and representation of data, it was possible to analyze and classify the works into 5 dimensions of cultural, spatial / geographical, ecological, economic, social and temporal sustainability. The search identified 83 TCCs, of which 28 presented key words with relevance to sustainability. At the end of this research one can observe the different relevant points of the production of the TCCs, as well as the interdisciplinary character intrinsic to the course.Este trabalho propõe a exploração, análise e representação dos Trabalhos de Conclusão de Curso para a obtenção do grau de Bacharel no curso de Tecnologias da Informação e Comunicação, da Universidade Federal de Santa Catarina, campus Araranguá, submetidos ao repositório da universidade. Tem como objetivo minerar estes TCCs, entre 2012 a 2015, através de técnicas de extração de conhecimento, usando ferramentas de representação do conhecimento, tornando os dados legíveis e passíveis de inferências, através da extração de diferentes termos nos TCCs, como: professor (a) ou orientador (a), palavras-chave, resumo, ano. Com a submissão às técnicas de extração e representação de dados foi possível analisar e classificar os trabalhos em 05 dimensões de sustentabilidade cultural, espacial/geográfica, ecológica, econômica, social e temporal. A busca identificou 83 TCCs, 28 apresentaram palavras-chave com referência à sustentabilidade. Como resultado, pode-se observar os diferentes pontos relevantes dos TCCs, bem como o caráter interdisciplinar intrínseco ao curso

Multilobular Tumor of Bone in a Dog

Background: Multilobular tumor of bone (MTB) is a primary bone neoplasm, uncommon in dogs. This tumor was called of many names for a long time, as: chondroma rodens, multilobular osteochondrosarcoma, multilobular osteoma, multilobular chondroma, calcificating aponeurotic fibroma, although MTB was preferred chosen, because these other name could be correlated with humans’ tumors. This tumor is observed specially in skull bone, although it was reported in zygomatic arc, hard palate, axilla, spine and penis. Mostly happen in big breeds dogs, and middle to old age patients. Clinical signs depending of region and how aggressive the tumor is, usually are related to compression of any structure. The growth of MTB is frequently slow and progressive, locally invasive, occurring relapse after surgical revomal, although the tumor has low to moderate metastatic potential. The aim of this study is to report a case of MTB in a female dog and describe anatomopathological changes.Case: A female dog, mixed breed, 13 year-old, of middleweight was admitted in Pathology Department of College of Agricultural Sciences and Veterinary Medicine (FCAV-Unesp), Campus of Jaboticabal - SP, to be undergone to necropsy. The patient have never shown any epileptic crisis or neurologic signs. In macroscopic examination was found a mass in skull, which invaded the orbit and frontal sinus, but it was not invading brain cavity. The neoplasm had and irregular surface, firm consistent, color was white mixed to red areas, after cut it was granular and rough, and had some point mineralized areas. The lobs of lung had much firm masses, colored gray to white. In cytology it was observed fusiform to polyhedric isolated mesenchymal cells, moderated pleomorphic, basophilic cytoplasm, thin granulated nuclear chromatin, and visible nucleoli that was involved by eosinophilic extracellular matrix. The proposed diagnostic was bone sarcoma. Histopathological assessment showed mesenchymal neoplastic proliferation, and multilobular characteristic, the lobules had different sizes and was well organized, and they were separated by thin conjunctive septs. In the center of lobules, there was an “island” with mineralized or chondroitin bone matrix, in some of these islands there were osteoclast. The cells had moderated pleomorphism and low mitotic activity (three mitotic cells in ten high-power field). At least, it showed big necrosis areas and invasion of near tissue. In lung was observed metastatic areas, which had same histopathologic way of primary neoplasm in skull. That way, the histopathologic exam was similar to Multilobular tumor of bone grade II.Discussion: The MTB is an uncommon neoplasm, which assaults mostly skull bone in large breeds dogs and middle age of eight years old. This case accord to literature about breed size, age and local of tumor.  The clinical signs in this dog was related to region what it was growing and near structure compression. Besides that, the patient had lung metastasis, that is the principal metastatic sites according to literature. The Histopathologic exam showed the same characters of MTB, which was considered grade II according to literature. Despite MTB is an uncommon neoplasm in clinic of dogs and cats, the epidemiological knowns as age, breed and localization, anatomopathological changes, and histopathological exam allows to have a diagnosis, showing the importance of including this neoplasm in differential diagnosis of bone tumor in dogs.
