Youths' Social Traits in Water Management as a Precursor for Good Water Governance
Authors: Gatt Kevin
Published: August 2017

Today's youths are yesterday's future generation and tomorrow's guardian of future generations. Successful water governance requires the sustainable management of water resources which in turn implies the maximisation of economic, social and environmental goals. This research, whilst focusing on the social traits of the current youth cohort, forms the basis of a wider national survey amongst Maltese society in order to identify their economic, social and environmental traits as one of the basis for developing a robust water governance framework for Malta. The research shows that whilst there is a solid foundation in the current youth crop to build upon for effective water governance, there is still considerable work that needs to be undertaken in order to raise awareness amongst a sizeable component of the current youth cohort.

Published: August 2017

This chapter is a continuation from Chapter 1. The two chapters draw attention to discussions on the Earth and its systems, which are driven by the outer motion of the Solar System. It gives an analytical view of what is known about the Universe. It elaborates upon the Earth's structure and the associated spheres and their interactions. These interactions account for activities that form the whole Earth dynamism, which manifest as tectonic movements, polar wondering and magnetic reversals, seasonal changes, hydrological cycle, atmospheric processes and life on Earth as a whole. The study of these is a fundamental component of geospatial science research.

Authors: Mfundisi Kelebogile B. , Mudabeti Alex M. , Makati Anastacia
Published: August 2017

Exposure to flood waters poses a risk to land productivity and livelihoods of communities in the Zambezi River Basin who are engaged in arable agricultural activities along its floodplains. This is exacerbated by occurrence of frequent flooding events in the area since 2008 due to climate variability. The objective of this research is to assess the extent of exposure to flooding on floodplain land used for maize production along the Zambezi River in Namibia. Existing survey information on geospatial locations of farms is used as baseline data. Field survey maps are then overlaid into flood maps developed using 2013 Landsat satellite data taken during peak flood event, and DEM. Weighted sum overlay results show that 14.5% of croplands were inundated with floods by March 2013. Integration of inundation results into a DEM show areas at low, medium and high risk to flooding. This provides useful geospatial information for flood mitigation.

Authors: Marin Mario Zasso , Júnior Cícero Jaime Bley , Gonzalez Rafael Hernando de Aguiar
Published: August 2017

Além da produção de alimentos e matérias-primas o espaço rural brasileiro tem se caracterizado, nas duas últimas décadas, pela incorporação de novas atividades, chamadas de atividades não agrícolas no rural (turismo rural, agroindústrias familiares, agroenergia). No Oeste paranaense, pertencente ao território da Bacia Hidrográfica do Paraná 3 (BP3), a pecuária (aves, suínos e bovinos) é uma das atividades desenvolvidas pela agricultura familiar que gera enormes quantidades de dejetos (biomassa residual). O objetivo desse artigo foi caracterizar o território da BP3 e destacar a sua vocação agroenergética como estratégia de geração de renda e emprego. Por meio de ações da Itaipu Binacional e demais parceiros na BP3 a biomassa residual da pecuária tem sido aproveitada por meio de biodigestores para a produção do biogás e do mesmo energia (elétrica e térmica), biofertilizantes e créditos de carbono. Trata-se de uma nova atividade que permite evitar a contaminação ambiental, gerar renda e promover o desenvolvimento rural sustentável.

Este artigo tem o objetivo de apresentar a micromobilidade física de trabalhadores-estudantes do curso de Geografia para a Unespar (Universidade Estadual do Paraná - Campus de Campo Mourão, PR). Partimos das propostas conceituais e metodológicas expressas por Rocha (1998) e com apoio cartográfico, buscamos respostas à seguinte questão: Como se articulam as micromobilidades dos trabalhadores-estudantes do curso de geografia gerados pela Unespar de Campo Mourão? Para tanto, utilizamos os programas Sphink Plus Léxica e Philcarto. Os resultados apresentados são referentes a pesquisa de TIDE (Tempo Integral de Dedicação Exclusiva). São informações coletadas em pesquisa exploratória por meio de entrevistas, a 57% dos acadêmicos que cursaram Geografia na Instituição, em 2013. Tratam-se de deslocamentos para a qualificação dos indivíduos, com o intuito de melhorar o seu status profissional, ocasionalmente motivados pela busca de maiores e melhores oportunidades de trabalho. Esta mobilidade é circunspeta por deslocamentos regulares (cotidianos) dos estudantes, originados na maioria das vezes de municípios da mesorregião Centro-Ocidental do Estado do Paraná como consequência da necessidade no ingresso no Ensino Superior. Assim, a busca pela formação de professores de Geografia em suas cidades de origem, leva muitos estudantes dos municípios próximos a Campo Mourão, a se deslocarem diariamente em busca de educação. Neste sentido, este estudo apresenta reflexões e contribuições acerca de aspectos importantes dentro dos estudos de desenvolvimento regional: as mobilidades ao trabalho e ao estudo.

Published: August 2017

A maioria das paisagens são influenciadas pela ação antrópica e o mosaico de paisagens resultante é uma mistura de elementos naturais e antrópicos que variam em tamanho, forma e arranjo, de modo que medidas usadas para descrever seus padrões, podem ser aplicadas na análise de sua estrutura. Desta forma, o presente estudo teve como objetivo analisar os efeitos da intensidade do uso e cobertura da terra sobre os padrões espaciais e temporais da paisagem de São Carlos, em 2003 e 2013, através do Índice de Qualidade Ambiental dos Recursos Hídricos, Índice de Qualidade Ambiental da Vegetação, Índice de Vulnerabilidade Ambiental, Índice de Densidade de Floresta Ciliar e Índice de Comprimento Médio de Fragmentos Florestais, no intuito de avaliar a condição de sustentabilidade ecológica da mesma. Identificou-se uma redução das áreas de vegetação nativa ao longo do tempo, com expansão das áreas agrícolas, evidenciando-se a diminuição da qualidade ambiental da paisagem. O crescimento das atividades antrópicas e a diminuição das áreas naturais podem levar a perda da biodiversidade e dos benefícios que estas proporcionam, as quais servem de suporte para manutenção das atividades urbanas e agrícolas de uma forma geral.

Authors: Photharin Somkuan , Tipparach Udom
Published: August 2017

We have synthesyzed TiO2 nanotubes by an anodization method. The cathode was titanium (Ti) sheets and anode was platinum (Pt). The electrolytes were mixtures of ethylene glycol (EG), ammonium fluoride (NH4F) and deionized water (DI water). The anodizing voltage was set to 50 V and the process was carried out for 2 h. The titanium foils were anodized at room temperature. Then Ag nanoparticles were loaded in TiO2 nanotube arrays by immersed in 50 ml solutions containing of AgNO3 (1.0, 1.5 and 2.0 mM) for 24 h. The morphology, structure, and optical properties of the prepared nanotubes were characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM) and and UV-vis spectroscopy (UV-vis) respectively. The structures of TiO2 nanotubes obtained from the nanotube arrays were crystallized by annealing at 450 °C for 2 h before immersed in solution and immersed in solution before crystallized by annealing are similar. When the concentration of silver nitrate (AgNO3) increases, the TiO2 nanotube arrays cracked and are not well arranged.

Authors: Zhu Guo Liang , Wang Rui , Wang Wei , Shu Da , Dong An Ping , Wang Dong Hong , Wang Jun
Published: August 2017

A novel method to remove impurity silicon from aluminum melt by the addition of K2TiF6 was studied. The mechanism for silicon removal is the formation and sedimentation of Ti(Al1-x,Six)3 phase and the removal efficiency is mostly decided by the solubility of silicon in TiAl3 phase, which increases with the increasing of the initial silicon concentration in aluminum melt. The effect of holding temperature on the impurity Si purification efficiency was investigated and the result indicated that the effect of holding temperature is very finite.

Authors: Liu Chang Yi , Zhang Bai Shou , Shrestha Suman
Published: August 2017

Drilling experiments of titanium alloy Ti6Al4V were conducted. Taking the speed and feed as the process variables, a set of experimental cutting forces are obtained and compared. From the experimental results it is concluded that within the experimental extent the thrust force and torque of drilling process rises with the feed rate. The lower spindle speed resulted in the greater amount of thrust. Feed rates have greater influence on the thrust force than the spindle speed. The combination of greater feed rate and lower spindle speed results in the maximum amount of thrust. However, combination of greater feed rate and spindle speed resulted in maximum amount of torque.

Published: August 2017

Thermally sprayed tungsten carbide-based coatings deposited by High Velocity Oxygen Fuel (HVOF) has been widely developed for its high corrosion and wear resistance. The finishing of the coated surface by grinding process is essential because of the high surface roughness of carbide coatings. Residual stresses existing in most hard coatings have significant influence on the adhesion, mechanical properties and tribological performance. The present study investigated the effect of grinding process on the residual stress of WC-10Co-4Cr coating by HVOF. The residual stress of coating was measured by the X-ray diffraction (XRD) technique using sin2ψ method. In addition, the effect of diffraction peak positioning method on the accuracy of residual stress of WC-10Co-4Cr coating was determined in the XRD technique. Four peak positioning methods and their effects on the accuracy of X-ray diffraction (XRD) residual stress measurement are considered. The results showed that the compressive residual stress of the WC-10Co-4Cr coating increase after grinding process. The parabolic method was selected for the peak positioning to measure the precise residual stress of HVOF-deposited WC-10Co-4Cr coating.

Published: August 2017

Aspect ratio of crack is one of key factors of fatigue strength prediction in engineering design and civil structures using fracture mechanics and nondestructive inspection. However the author proposed the method to predict crack shape, it has the error caused by stress distribution of notch. In this study, in order to investigate the relationship between predicted crack shape and empirical observed it, the aspect ratio of cracks at notch root was observed, analyzed and discussed. We obtained the two important conclusions which are between predicted crack shape and empirical observed it. Predicted aspect ratio of crack was 17% bigger than that of observation result. The aspect ratio of crack should be defined considering scale of crack and notch shape.

Published: August 2017

Using samarium (III) nitrate hexahydrate, manganese nitrate and citric acid as main raw materials, the SmMnO3 gel was prepared by sol-gel process. The gel was kept at 100 °C for 24 h to get the xerogel. Then, the xerogel was respectively calcined in muffle furnace at 600 °C, 700 °C, 800 °C and 900 °C. The structure and morphology of samples were characterized by powder X-ray diffraction (XRD), scanning electron microscopy (SEM) and Fourier Transform Infrared (FT-IR) spectroscopy. The UV photocatalytic activities of SmMnO3 were investigated by methyl orange which was used as simulated sewage. The results show that the pure SmMnO3 can be obtained through calcination between 700 °C and 800 °C, and the SmMnO3 have an average particle size of 80 nm. The SmMnO3 samples calcined at 700 °C and 800 °C show high photocatalytic activity for decomposition of methyl orange under UV-light irradiation. The SmMnO3 samples are consistent with first-order kinetics for the degradation of methyl orange. And the apparent rate constants are respectively k700 =0.01206 min-1and k800=0.01088 min-1.

Authors: Zhang Yan , Xu Qing Nan , Li Yang Wei , Yang Ti , Sun Yan Zhou
Published: August 2017

In this paper, the emission spectra of the atmospheric N2 and N2/CO2 DBD plasma being processed by PP sample are analyzed. The results indicate the spectrum lines of oxygen atoms ion (O+) in the region of 382.1 nm - 389.3 nm and 412.1 nm - 421.3 nm are observed in N2 plasma. However, the spectrum lines of O+ has absolutely disappeared, furthermore the γ spectrum band of NO in the region of 270nm-325nm has appeared in N2/CO2 plasma because the metastable nitrogen molecules () are quenched by CO2 molecules. This causes that the collision of the metastable nitrogen molecules () and PP sample surface were reduced and ultimately leads to a reduction in the treatment effect of the N2/CO2 plasma on the surface of the PP sample. Therefore, this indicates the metastable nitrogen molecules () in the plasma region plays a key role in improving the characteristics of the PP surface.

Published: August 2017

One of the main shortcomings of individualized training in the use of computer aided design (CAD), and computer aided manufacturing (CAM) tools is that students lack a sound and broad understanding of the type of tools, and their specific and integrated applications in industrial manufacturing. This study aimed to design an integrated curricular training programme in computer aided tools for the design and manufacture of mechanical components based on reverse engineering techniques. By using real products that students can see and touch, a scanned copy is obtained for subsequent reconstruction into a virtual three-dimensional model using the software for optimizing the point cloud, meshing, and creating both the surface and solid. Once the virtual three-dimensional model has been obtained, it is exported to a solid modelling CAD (3D-CAD) software for modification according to the geometrical requirements. The next step is for students to manufacture a component using rapid prototyping techniques, which allow them to visualize, analyse, and inspect a component to optimize its design. The use of computer aided manufacturing software enables students to design and plan machining operations virtually to obtain a computer numeric control (CNC) program for the manufacture of a component with a CNC machine tool. Finally, students perform a quality control of the component by employing a range of measurement techniques. This training program is integrated into the subjects of the mechanical engineering degree, where students can work with these tools in line with an intergraded curriculum.

Initiating a different story about immigrant Somali parents’ support of their primary school children’s education
Authors: Daniels Doria
Published: August 2017

The ability of parents to nurture and support their children during their primary school years is considered to be fundamental for the child’s development and learning. Teachers and educational psychologists assign great prominence to parental involvement as a tool to advance educational success for children, especially for those who are faced with disadvantages. In the past two decades, we have seen South African schools radically shifting from being racially and ethnically homogenous to becoming culturally, ethnically and linguistically heterogeneous. It is especially the schools in the lower socioeconomic areas that find themselves under tremendous pressure to serve their growing immigrant school population. Not enough is known about the cultural capital that lies embedded in these learners’ home contexts and the roles that their parents play in their education. In this manuscript, I investigate the potential intersectionality of school and home and critique the affiliation between teachers and immigrant parents as an important dimension of learning success in the primary school. I situate the discussion in a community school with a strong Somali immigrant population.
Community development workers as agents of change and conduit of authentic public participation: The case of Mpumalanga Province in South Africa
Authors: Mokoena Sipho K. , Moeti Kabelo B.
Published: August 2017

This article explores the role of community development workers (CDWs) in the Mpumalanga Province of South Africa. The CDWs are by law expected to regularly communicate, inter alia, government initiatives in a way which is easily accessible to community members. Literature shows that the CDWs forward concerns and issues on the service provided by national and provincial government in general, and local government to be specific. This article acknowledges that CDWs share the working space with Ward Committees who have a direct say in the planning, decision-making and project implementation that have impact on their respective wards. The question that this article attempts to answer is whether the establishment of CDWs in the country has achieved the desired result to the extent that it can be recommended for permanent incorporation in the local municipality structures. The research design used in this article was a qualitative method. Data were collected through extensive review of public documents, accredited journal articles, observations and interviews. The results showed that the CDWs coordinate teams of volunteers in community projects, coordinate teams employed on public works programmes, help communities develop and submit proposals for inclusion in integrated development plans to municipalities, and other spheres of government or donors. Furthermore, the roles and functions of both CDWs and Ward Committees do overlap. It is very difficult for the local communities to differentiate between these two structures.
Lombaard's categorical invitation for minority dissent against 'suspicion': How real is the 'religious' in post-secular context?
Authors: Schreiber Dudley A.
Published: August 2017

In the broader context of post-secularism and Lombaard’s contributions, needful of philosophy, this minority report lights upon an analytic–post-secular crossover. Here, responding to Lombaard’s categorical quest for the ‘religious’, philosophy serves to support greater realism in the discourse of the philosophy/sociology of religion so that we might better consider social, spiritual and philosophical capital. By small means, focusing on ontological, relational, democratic, psychological, social and analytic features of the humble category, it is suggested that an attitude of mitigated realism serves best in relief from suspicious theoretical pasts.Intradisciplinary and/or interdisciplinary implications: This article attempts to demonstrate how post-secular categories like that of the ‘religious’ are enriched in post-analytic engagement with European philosophy and what this might require of theory.

Published: August 2017

Abstract. Small phytoplankton are anticipated to be more important in a recently warming and freshening ocean condition. However, little information on the contribution of small phytoplankton to overall phytoplankton production is currently available in the Amundsen Sea. To determine the contributions of small phytoplankton to total biomass and primary production, carbon and nitrogen uptake rates of total and small phytoplankton were obtained from 12 productivity stations in the Amundsen Sea. The daily carbon uptake rates of total phytoplankton averaged in this study were 0.42 g C m−2 d−1 (SD  =  ± 0.30 g C m−2 d−1) and 0.84 g C m−2 d−1 (SD  =  ± 0.18 g C m−2 d−1) for non-polynya and polynya regions, respectively, whereas the daily total nitrogen (nitrate and ammonium) uptake rates were 0.12 g N m−2 d−1 (SD  =  ± 0.09 g N m−2 d−1) and 0.21 g N m−2 d−1 (SD  =  ± 0.11 g N m−2 d−1), respectively, for non-polynya and polynya regions, all of which were within the ranges reported previously. Small phytoplankton contributed 26.9 and 27.7 % to the total carbon and nitrogen uptake rates of phytoplankton in this study, respectively, which were relatively higher than the chlorophyll a contribution (19.4 %) of small phytoplankton. For a comparison of different regions, the contributions for chlorophyll a concentration and primary production of small phytoplankton averaged from all the non-polynya stations were 42.4 and 50.8 %, which were significantly higher than those (7.9 and 14.9 %, respectively) in the polynya region. A strong negative correlation (r2 = 0. 790, p<0. 05) was found between the contributions of small phytoplankton and the total daily primary production of phytoplankton in this study. This finding implies that daily primary production decreases as small phytoplankton contribution increases, which is mainly due to the lower carbon uptake rate of small phytoplankton than large phytoplankton.

Abstract. In recent years, monitoring of the status of ecosystems using low-cost web (IP) or time lapse cameras has received wide interest. Networked cameras can provide information about snow cover and vegetation status with a broad spatial coverage and high temporal resolution, and serve as ground truths to earth observations, and be useful for gap-filling of cloudy areas in earth observation time series. Networked cameras can also play an important role in supplementing laborious phenological field surveys and citizen-science projects, which also suffer from observer-dependent observation bias. We established a network of digital surveillance cameras for automated monitoring of phenological activity of vegetation and snow cover in the boreal ecosystems of Finland. Cameras were mounted at 14 sites, each site having 1–3 cameras. Here, we document the network, basic camera information and access to images (see, https://doi.org/10.5281/zenodo.777952) in the permanent data repository (https://www.zenodo.org/communities/phenology_camera/). Individual DOI-referenced image time series from cameras are consisted of half-hourly images collected between 2014 and 2016. Additionally, we present example colour index time series derived from image time series from two contrasting sites.
Understanding of morphometric features for adequate water resource management in arid environments

Abstract. Hydrological characteristics such as topographic parameters, drainage attributes, and land use/land cover patterns are essential to evaluate the water resource management of a watershed area. In the current study, delineation of a watershed and calculation of morphometric characteristics were undertaken using the ASTER global digital elevation model (GDEM). The drainage density of the basin was estimated to be very high, which indicates that the watershed possesses highly permeable soils and low to medium relief. The stream order of the area ranges from first to sixth order, showing a semi-dendritic and radial drainage pattern that indicates heterogeneity in textural characteristics, and it is influenced by structural characteristics in the study area. The bifurcation ratio (Rb) of the basin ranges from 2.0 to 4.42, and the mean bifurcation ratio is 3.84 in the entire study area, which signifies that the drainage pattern of the entire basin is controlled much more by the lithological and geological structure. The elongation ratio is 0.14, which indicates that the shape of the basin has a narrow and elongated shape. A land use/land cover map was generated by using a Landsat-8 image acquired on 10 August 2015 and classified to distinguish mainly the alluvial deposit from the mountainous rock.
Continuum model of wave propagation in fragmented media: linear damping approximation
Authors: Khudyakov Maxim , Dyskin Arcady V. , Pasternak Elena
Published: August 2017

Abstract. Energy dissipation during wave propagation in fragmented geomaterials can be caused by independent movement of fragments leading to energy loss on their impact. By considering a pair of impacting fragments at times much greater than the period of their oscillations, we show that at a large timescale, the dynamics of the pair can be described by a linear viscous model with damping coefficients expressed through the restitution coefficient representing energy loss on impact. Wave propagation in fragmented geomaterials is also considered at the large timescale assuming that the wavelengths are much larger than the fragment sizes such that the attenuation associated with wave scattering on the fragment interfaces can be neglected. These assumptions lead to the Kelvin–Voigt model of damping during wave propagation, which allows the determination of a dispersion relationship. As the attenuation and dispersion are not related to the rate dependence of rock deformation, but rather to the interaction of fragments, the increased energy dispersion at low frequencies can be seen as an indication of the fragmented nature of the geomaterial and the capacity of the fragments for independent movement.

La responsabilidad y la solidaridad como valores que alimentan los sentimientos de comunidad y fundamentan la ética (MORIN, E.; 2006: 25), así como las actitudes que se fundan en ellos, se adquieren y desarrollan mediante la experiencia y las prácticas sociales. A su vez y dado el escenario de crisis civilizatoria en el que estamos inmersos, la educación con y para la solidaridad y la responsabilidad se constituye en un imperativo moral de primer orden por

lo que todas las instituciones educativas en general y las de Educación Básica y Obligatoria en particular deben asumir la responsabilidad social de educar en estos valores, aprovechando todas las posibilidades que brindan las mismas. Obviamente esto exige esfuerzos y compromisos

multidimensionales, sostenibles y perdurables de carácter político, estructural, organizativo, curricular, educativo, docente y comunitario que pueden y deben estar dirigidos

a construir y a desarrollar Escuelas Solidarias. Sin embargo esta aspiración que late y existe seminalmente en muchas de nuestras actuales escuelas, no podrá germinar y dar frutos si

la solidaridad, la responsabilidad y la confianza no se constituyen como formas habituales, cotidianas y naturales de vida, trabajo, aprendizaje y convivencia. En esta línea, el presente artículo intenta aportar diversas reflexiones y sugerencias de carácter teórico y práctico basadas en las experiencias de su autor y orientadas a hacer posible la construcción y el desarrollo de una Escuela Solidaria.

Behrens, Carlos Rodrigues Brandão, Maria José de Pinho e vários outros que consubstanciam as elocubrações aqui colocadas. Não há a intenção aqui de comprovação do que foi dito, mas de incitar novas reflexões a partir do tema que suscita, na atualidade, uma ideia de transformação

da educação, a partir, nesse caso, da transformação da escola como desenvolvedora do seu próprio potencial criativo, assim como de seus alunos. Assim, para iniciar esse diálogo, procuro responder à diversas perguntas que se me surgem sobre a pergunta inicial. E assim se segue...
Educação para paz: um caminhar no pensamento complexo através de cinco pedagogias integradas e complementares
Authors: Salles Filho Nei Alberto
Published: August 2017

Este artigo apresenta os elementos centrais da tese intitulada “Cultura de Paz e Educação para a Paz: olhares a partir da Teoria da Complexidade de Edgar Morin”, defendida no Programa de Pós-Graduação em Educação – Mestrado e Doutorado, da Universidade Estadual de Ponta Grossa, Paraná. A tese, de caráter teórico-reflexivo, que tem como objeto de estudo a Educação para a Paz à luz do pensamento complexo, propõe que os processos relacionados às violências e convivências escolares, ganham maior sentido se pensados na integração entre cinco dimensões fundamentais, de)nidas como as “cinco pedagogias da paz”: Pedagogia dos Valores Humanos, Pedagogia dos Direitos Humanos, Pedagogia da Conflitologia, Pedagogia da Ecoformação e Pedagogia

das Vivências/Convivências. No decorrer do artigo, argumentamos sobre tais relações. Com a tese em questão, pretende-se avançar na construção da Educação para a Paz como campo de conhecimento e pesquisa no Brasil.

A Escola Comunitária Cirandas foi fundada em 2014 com o intuito de construir um projeto de transformação social através da educação. Atualmente, recebe 53 crianças agrupadas em um único ciclo, equivalente do 1o ao 5o ano do Ensino Fundamental. O processo de ensino e aprendizagem realiza-se através de pesquisas e projetos idealizados pelas crianças, em parceria com toda a comunidade escolar. Não temos provas, notas ou uniformes. Acreditamos no diálogo como base para a construção coletiva do conhecimento, assim como valorizamos diferentes formas de saber e aprender. A metade dos alunos tem bolsas escolares, na intenção de construirmos um ambiente sociodiverso. A diversidade social permite amplitude nas relações sociais, na visão de mundo e na formação integral do ser humano.

Published: August 2017

Este artigo originou-se do desejo de que os fazeres e os saberes vivenciados na Escola Casa Verde, Aparecida de Goiânia, Goiás/Brasil, ultrapassassem os muros da Escola. Trabalho baseado em muitos anos de estudos e prática. Planejado na tentativa de romper com a pratica tradicional

desde o início. Nesse fazer, a comunidade escolar e as crianças vivem a experiência de lapidação feito pedra preciosa na direção do sonhado. Este texto tem como objetivo apresentar a Escola, descrever o processo criativo do trabalho pedagógico e justificar a quebra de paradigma na linha de atuação que tece a dinâmica escolar. Contudo, sabemos que as palavras fogem, deixam de alcançar a dimensão do objeto observado. A riqueza do vivido ultrapassa a capacidade do registro. O principal, nessa tarefa, é afirmar que a Casa Verde troca a inércia repetidora por experiências e acontecimentos vinculados à vida que pulsa fora dos muros da escola.
