Observa-se como estratégia mundial para a conservação da biodiversidade a criação de unidades de conservação. No Brasil, especificamente no Estado de São Paulo, devido a intensa degradação da Mata Atlântica, verifica-se a criação de unidades de proteção integral, a fim de se preservar de modo restrito os recursos naturais que ainda lhe restam. Na cidade de Ribeirão Preto, uma região com alto desempenho agrícola e intensa expansão urbana, constata-se a presença de uma Estação Ecológica (EERP), fragmento florestal de 154,16 ha, altamente isolado e fragmentado. Assim, a EERP e sua zona de amortecimento (ZA) vêm sendo fortemente pressionada pela expansão urbana e agrícola da região, comprometendo a sua integridade ecossistêmica. Dentre os impactos negativos gerados destacam-se: alta especulação imobiliária e o intenso cultivo de monoculturas, que contribuem para a degradação do solo nas regiões do entorno. A fim de se reduzir tais impactos, o presente trabalho buscou apresentar um prognóstico de planejamento ambiental para a ZA da EERP, a qual se encontra altamente impactada, segundo os critérios definidos por Ranieri (2004). Desse modo, criou-se cenários ideais para a preservação dos recursos naturais do local

The present work aims to draw some reflections on the role of art in integral education, particularly of art as a school subject. The paper focuses on the contribution of art to the development the individual and the higher psychological functions. The arguments presented here are based on the studies on art made by Lev Vygotsky and Georg Lukács and also on the educational studies made by Dermeval Saviani. We expect to contribute to the defense of the necessity of an integral education in which art, integrated with science and philosophy, opposes itself to the predominantly fetishistic and unilateral character of the activities that constitutes the life in the contemporary capitalist society.

The purpose of the present paper is to study some properties of solutions of Volterra integral equations on time scales. We generalize to a time scale some known properties concerning continuity and convergence of solutions from the continuous case.

Let m >= 3 be an integer, zeta(m) is an element of C a primitive mth root of unity, and K-m the cyclotomic field Q(zeta(m)). An explicit description of the integral trace form Tr-Km/Q(x (x) over bar)vertical bar Z[zeta(m)] where (x) over bar is the complex conjugate of x is presented. In the case where m is prime, a procedure for finding the minimum of the form subject to x being a nonzero element of a certain Z- module in Z[zeta(m)] is presented.

No Brasil a educação é um tema delicado, com histórico de índices de reprovação e evasão escolar altos, escolas públicas em condições precárias em muitas regiões e profissionais da área pouco valorizados. As políticas públicas são uma importante ferramenta quando se busca sanar todos estes problemas. Uma proposta que vem sendo implantada no Estado de São Paulo é o das Escolas de Tempo Integral, em que os alunos têm a oportunidade de passar mais tempo na escola, com atividades diferenciadas e um modelo diferente da escola comum. Assim, este trabalho tem como objetivo analisar a proposta do modelo e a implementação do mesmo na Escola Estadual Carolina Augusta Seraphim, localizada em Rio Claro. Para a análise de conteúdo, realizada neste trabalho, foi feito o levantamento de material bibliográfico referente ao tema de Escola de Tempo Integral, principalmente no Estado de São Paulo. Também foram analisados documentos e materiais disponíveis no blog da EE Carolina Augusta Seraphim. Podem ser destacados pontos positivos do Programa, como a dedicação exclusiva da equipe gestora, a valorização dos profissionais envolvidos, a participação mais aproximada da comunidade e família dos alunos, a possibilidade que os estudantes têm de pensar e planejar seu futuro. Existem ainda questões a serem melhor debatidas, analisadas ou até mesmo aprimoradas, devido às particularidades de cada escola e até mesmo inovações tecnológicas que podem ser usadas como ferramentas de ensino. Essas são algumas das questões abordadas e analisadas ao longo do trabalho

EE Prof. Carolina Augusta Seraphim, School of Basic Education Cycle II, located in the municipality of Rio Claro in São Paulo, adopted the new Model School of Integral Education in 2013 from analysis and studies of state and local experiences, as an alternative to the demands of the public. The objective of the study is to characterize the operation of this new teaching model implemented by the Secretary of Education of São Paulo, based on the experiences gained through this school in the city of Rio Claro. This is a documentary research that was grounded on the content analysis of documents relating to the design of the program and the school to be searched. Having the information gathered will be compiled and analyzed using the theoretical framework as bibliographies of authors related to the topic, resulting in discussions about the recovery and casualization of teaching about this new teaching model

Studies show that the disciplines of differential and integral calculus have high failure rates in all schools where they are present and, although this problem has been accentuated in recent years, it is not a local phenomenon. It's observed since 1970s in various Institutions of higher education in Brazil. These studies seek to understand the causes of failures and proposals for teaching methodology that aims to help reduce these rates. However, there is a large contingent of students who are successful at the first time that they perform these disciplines. And these cases, although they have not been studied, can contribute greatly to the understanding the aspects that are related to learning of them. And this understanding can lead to attitudes and learning and teaching methodologies that promote the expansion of this success. The fact that these subjects also have high failure rates in the Degree in Chemistry of this Institute, this study aimed to investigate the factors that were relevant to the cases for approval of the students performed for the first time. For this we constructed a questionnaire containing objective questions and open answers. The objective sought to diagnose the profile of these students with regard to age, gender, basic education (elementary and middle school), study habits, concurrent activities, among others. These questions were analyzed using simple statistics. The open-ended questions asked students to indicate that they attribute the success obtained in the disciplines and to suggest modes of study. These questions were analyzed using thematic categorization, a method of content analysis. This questionnaire was completed, voluntarily and without identification, by students who have passed the first time attended the courses Calculus I and/ or Calculus II and had never started another college prior to this. The results indicate that the most relevant factors in this process were dedication and correct habits...

The aim of this study was to evaluate the biological properties and biocompatibility of bovine non-demineralized lyophilized and composite bones implanted in tibiae bone cavities and at the subcutaneous level. Twenty-four rats were used and sacrificed 15 and 45 days later. At the subcutaneous level, after 15 days an inflammatory reaction was seen around biomaterial particles with the presence of giant cells and at 45 days fibrous connective tissue had also developed. No signs of ectopic bone formation were observed at tibiae regions; more bone neoformation was observed at the control group (15 days) with 42.8% of the outer cortex layer against 22.6% at Orthogen and 25% at GenMix groups. At 45 days, correspondent values for bone neoformation were 62.5% at control, 26% at Orthogen, and 35% at GenMix groups, respectively. It can be concluded that both materials tested were biocompatible aiming to bone neoformation by their osteoconductive properties with no ectopic formation sites observed.

This study aims to evaluate the quality of life of students aged 7 to 12 years in two municipal schools in the municipality of Minas Gerais. One offers full-time care to their students with extracurricular activities and other school offers only the normal. We used the questionnaire AUQEI, Autoquestionnaire Qualité de Vie Enfant Image. The questionnaire was administered to 232 children. Through this study, we observed that the proportion of children with a good Quality of Life was higher in school full time (81%), compared to the normal school hours (58%). Therefore, it is concluded that the school offers an extended workday, is set in an area rich able to develop the maximum potential of children and their personal skills, which will reflect positively on their quality of life.
