Sustainability in projects in the view of students and graduates of the Technical Building Course
The need to reconcile economic and social progress with the preservation of natural resources has
become increasingly necessary, as well as the training of building technicians with the theme of
sustainability. The Teaching Institution plays an important role in the formation of the individual,
because it is through it that the construction of ethical principles occurs, in addition to the social
and cultural relationship. The insertion of themes that deal with the development of sustainable
projects, assists in the mitigation of environmental impacts. The present work aims to analyze how
sustainability is being worked during the middle level course in Building Technician. The research
was conducted from an online form, answered by course students and trained technicians. hrough
the results, it was concluded that educational institutions need to address more content related to
sustainability in the classroom
A BELEZA SECA: ASPECTOS DO PAISAGISMO NO SEMIÁRIDO BRASILEIRO
A conservação dos escassos recursos hídricos na região Nordeste do Brasil exige um programa de gerenciamento mais eficiente. A má distribuição pluvial na localidade, a urbanização e as secas periódicas intensificam a demanda por água. Entretanto, a ocupação urbana ainda modifica a morfologia espacial sem se atentar para o potencial paisagístico natural, enquanto busca reproduzir padrões estéticos externos e distintos. Diante disso, faz-se necessária a percepção da urgência de minimizar o desperdício de água. Remodelar a paisagem através de planejamento e modificações adequadas não só ajudam a reduzir seu consumo, mas também os custos com sua manutenção. Nesse sentido, o presente trabalho apresenta soluções paisagísticas mais eficientes em termos de economia hídrica e combate à desertificação na região semiárida brasileira. Técnicas como ordenamento da flora por necessidade de água, elaboração de oásis artificiais, utilização de mantas e quebra-ventos demonstram eficiência quando aliados aos mecanismos de sobrevivência inerentes à vegetação nativa
A beleza seca: aspectos do paisagismo no semiárido brasileiro.
The conservation of scarce water resources in Northeast region of Brazil requires a more efficient
management program. The bad rainfall distribution on site, urbanization and periodic droughts
intensify the water demand. However, the urban occupation still modifies the spatial morphology
without noticing the natural landscaping potential, while seeking to reproduce aesthetic external and
different patterns. Therefore, it is necessary the perception of the urgency of minimize the waste of
water. Reshaping the landscape through suitable planning and modifications not only help reduce
its consumption, but also maintenance costs. Thus, the present work presents more efficient
landscaping solutions with regard to water economy and fight against desertification in Brazilian
semiarid region. Techniques such as plant sorting due to the water need, elaboration of artificial
oasis, using mulches and windbreaks demonstrate efficiency when allied to the survival mechanisms
inherent to native vegetation
The position of the students of Environmental Engineering and Civil Engineering of the Federal Institute of Bahia in relation to Sustainability in the Civil Constructions of Brazil
The objective of this article is to discuss sustainability in civil construction presenting the concept
of the theme, arguing about the difficulties and advantages in conciliating constructions with the
balanced environment. n addition to presenting innovations in the area of construction such as the
'' Green Roof '' and the '' Brick Pet ''. With the purpose of discussing the subject also in the
academic environment, a questionnaire was made presenting the opinion of the upper level
students of the courses of Environmental Engineering and Civil Engineering Of the initial
semesters, in which each student presented his opinion on the subject treated, sustainable
construction. The work was conceived as an exploratory and descriptive research of quantitative
character. It is concluded after analysis that investments need to be made to increase sustainability
more and more in the constructions of Brazil and the world, in addition to public policies that
arouse an interest for sustainable materials by companies and contractors responsible for works
Green buildings: a vision of engineers in relation to the implementation of sustainability in the development of civil projects.
Construction is a transformation sector, due to this, it is acknowledged that it can cause various
environmental impacts. Hence, there is a general concern, in the civil society, over the damages
that can be caused by this sector once that it is known as strategic for economic growth but it
usually causes environmental harm and generates a great amount of solid waste. The necessity in
promoting a plan that aims to preserve the environment through sustainability in construction
projects has become a driven factor in the professional qualification of engineers. This paper aims
to analyse the conception of engineers referring to the adoption of sustainable practices in their
projects; besides, this paper also aims to identify ecological practices adopted during engineers
projects. To achieve this, the following step was adopted: A survey was conducted amongst
engineers in order to gather information for further data analysis and an awareness work over the
impacts of badly designed projects over the environment was carried out
A proposal of a cryptographic system of public key using classical and quantum convolutional codes
Orientador: Reginaldo Palazzo JuniorDissertação (mestrado) - Universidade Estadual de Campinas, Faculdade de Engenharia Eletrica e de ComputaçãoResumo: A proposta de um sistema criptográfico de chave pública que utiliza códigos convolucionais de memória-unitária clássicos e quânticos apresentada neste trabalho, está baseada na utilização de transformações armadilha que, ao serem aplicadas as submatrizes reduzem a capacidade de correção de erros do código. Este processo proporciona um aumento no grau de privacidade da informação a ser enviada devido a dois fatores: para a determinação de códigos ótimos de memória unitária è necessário resolver o Problema da Mochila e a redução da capacidade de correção de erro dos códigos ocasionada pelo embaralhamento das colunas das submatrizes geradoras. São também apresentados neste trabalho, novos códigos convolucionais quânticos concatenados [(4, 1, 3)].Abstract: The proposal of a cryptographic system of public key that uses classical and quantum convolutional codes of unit-memory presented in this work, is based on the use of trapdoors functions which when applied to submatrices reduce the capacity of correction of errors of the code. This process gives us an increase in the degree of privacy of information being sent, because of two factors, namely: to establish good unit-memory codes is necessary to solve the knapsack problem, and the reduction of the capacity of correcting errors of codes provided by scrambling the columns of generating submatrices. We also present in this work, news quantum convolutional codes [(4, 1, 3)].MestradoTelecomunicações e TelemáticaMestre em Engenharia Elétric
REWAT: Sustainable Rainwater Reuse
O homem, desde o início das primeiras sociedades, começou a extrair da natureza, de maneira
predatória, os recursos necessários para o sustento da civilização e muitos projetos já evoluíram
através das Tecnologias da Informação e Comunicação (TICs), mas ainda continua intrínseco à
realidade nacional, o pensamento contrário ao ambiente natural. Dessa forma, esse artigo, através
de pesquisas de projetos similares, aquisição dos materiais para a construção do protótipo e
pesquisas de validação comercial, tem como objetivo descrever aspectos do projeto do
reaproveitamento sustentável da água da chuva, buscando refletir e destacar a importância do
empreendedorismo sustentável para o desenvolvimento econômico e social nessa ordem
econômico-ecológica do país com o fito de resolver as dores da escassez da água para pessoas
físicas, fábricas, shoppings ou estabelecimentos comerciais. Sendo assim, os resultados indicam
que estabelecimento comercial é o segmento de mercado com maior expressividade e a fim de
deixar o KIT mais acessível é necessário pensar ações efetivas de formas de pagamento e custos de
manutenção, sendo essencial a educação dos clientes para eficiência do processo de interação da
REWAT, bem como as ações integradas do projeto sirvam de base para formação de um cidadão
planetário crítico, ético e capaz de mobilizar e transformar a realidade.From the beginning of the early societies, man began to extract predatory resources from nature in
order to sustain civilization, and many projects have already evolved through Information and
Communication Technologies (ICTs), but are still intrinsic to reality national, the contrary thought
to the natural environment. Thus, this article, through researches of similar projects, acquisition of
materials for the construction of the prototype and commercial validation research, aims to
describe aspects of the project of the sustainable reuse of rainwater, seeking to reflect and
highlight the importance of entrepreneurship sustainable economic and social development in this
economic-ecological order of the country with the purpose of solving the pains of water scarcity
for individuals, factories, malls or commercial establishments. Thus, the results indicate that
commercial establishment is the market segment with greater expressiveness and in order to make
the KIT more accessible it is necessary to think about effective actions of payment methods and
maintenance costs, being essential the education of the clients for efficiency of the process of
interaction of REWAT, as well as the integrated actions of the project serve as the basis for the
formation of a planetary citizen who is critical, ethical and capable of mobilizing and transforming
reality
