Abstract: Human beings have never removed so much of the environment as in recent years. Guided byvalues based on consumerism, they have entered in the dynamics of nature. Removing from it at anycost, its resources: minerals, flora, fauna, besides water, soil and which become more and more aplace of discharge of various pollutants. As a result of this society of consumerism, waste appearsas na ally, producing thousands of tons of garbage daily by human beings. Recently, the politics ofthe administration of urban solid residues in Brazil created by the Federal Government, whichincludes the support of organizations of collectors of recycled waste, has encouraged the implanta-tion of the selective collection of garbage and the passing on of funds for the implantation of sanitary landfills in municipal districts. In Araguari (MG) this process began in 2001. This was themoment in which we participated more directly in the implantation of the selective collection. A lotof experience was accumulated during this participation, especially the implantation of the selec-tive colletion in schools of the municipal district. In this article, we will make reference to theseexperiences, contemplating the misunderstandings and the progress conquered. With this, webelieved to be contributing with those who want, in the school context, to begin or to reformulateways in the universe of the separation of materials be sent to recycling industries.

Revista Sociedade & Natureza , 2004,
Abstract: More than a confinde science, Ecology shows us today how to see life and act in ti. In recent years, Deep Ecology a proposal by Arne Naess in 1973, has brought up questions that make us review our concepts and attitudes by proposing that each individual opens themselves to a personal revolution, changing their deportmente in light of the world. After advancing for o long period of time without objetcitves and clear methodologies, formal Environmental Education is beginning to be seen and lived as na important dimentsion in the educational process. This process, individual criticisms and is capable of constructing alternative ways to minimize social environmental problems. For this to happen, a scholl in its totality, must turn to na integrated work which the complexity of relations is developed to be a reference to the definition of its pedagogical proposal.

Lena Lendahls, Ingrid Edvardsson
Health (Health) , 2018, DOI: 10.4236/health.2018.105044
Abstract: Aims and objectives: To examine health and well-being, as well as the need for support among children and parents where the child has T1DM with low HbA1c (<52 mmol/mole). The purpose was also to investigate the extent to which children’s and parents’ experiences match. Introduction: Studies have shown that children with diabetes type 1 (T1DM) rate their lives as worse than healthy peer ratings. In Sweden, views have been expressed that children, as well as their parents, feel pressurized by the diabetes teams to achieve low HbA1c values, which can lead to poorer mental health for the family. Design: A qualitative study. Methods: A consecutive sample of 11 children and their parents (one father, ten mothers) was interviewed together but individually guided by a semi structured interview guide. Interviews were analyzed using thematic content analysis. Results: Four main categories were consistent across children and their parents; 1) attitude to the illness, 2) sadness about diabetes, 3) the importance of the social network, and 4) the importance of the diabetes team. Worries about hyperglycemia were more prominent than worries about hypoglycemia in both children and parents. A distinguishing feature of the interviewed children was that they were responsible, strict and targeted. Many of them were competitive and took part in various sports, even at a very advanced level. Conclusions: This study shows that children with low HbA1c values experience good health and good well-being. Family support, good planning, and high acceptance of their illness contributed to this.

Abstract: domestic ordinary drilling machines have been used in orthopedic surgeries in brazilian hospitals, for bone drilling. however, it is an electric thermo-sensitive appliance, non-specific for surgical use, not assessed in terms of sterilization efficiency, as well as on potential surgical infections associated to its use. the objective of this review was to describe the state-of-the-art use of domestic drills in orthopaedic surgeries, considering the difficulties of cleaning and sterilization. the lilacs and medline databases were consulted using mesh and free medical terms, without time restraints. two specific articles were found about the use of domestic electric drills in orthopaedic surgeries. in the first article, the author suggests the disposal of the equipment in cases of any noticeable blood contamination that could result in difficulties to clean it. the second article describes how to adapt a domestic drilling machine for orthopaedic surgery, but the sterilization process is performed by using formalin tablets at room conditions. further studies are required for evaluating the current practice and to recommend safe conditions for its use or towards giving it up.
