For centuries have studied the man in a segmented manner, which today, even with the emergence of new forms of research, holistic, we see that the influence of centuries of construction of scientific knowledge has taken root in such a way that even now with new understandings about matter and its structure pointing to systemic relations, studies are still largely dichotomized by dividing body, mind and environment. This paper is a literature review on several sources of knowledge, seeking an interdisciplinary way in physics, chemistry, biology, psychology and physical education, relate the body, mind and their interactions with the environment, building a more current concept of body. The studies showed that the physical, cognitive, emotional, social and environmental aspects involve an interaction continues between human been with the world, which changes shapes, balances and transactions, and thus human behavior. So when we speak of the body should relate all this that makes us conscious organisms in constant internal and external dynamic with the universe

Quality is a variable concept, which involves many factors, depending on the consumer market. In meat production, the concern with environmental aspects, animal welfare and the health and safety of workers is increasing. This work studied the effect of controlled atmosphere stunning of broilers on meat features and biochemical parameters for stress. Cobb broilers were stunned by electrical stunning and by controlled atmosphere with 70% CO2 and 70% CO2 + 30% Argon. After stunning, serum levels of glucose, lactate and corticosterone were compared with those of broilers at rest, immediately before transportation and slaughter and after 12 h of feed withdrawal (control group). At slaughter, blood volume drained during bleeding was not different for the stunning methods tested, ranging from 3.3 to 3.4% birds weight. This finding was important to demonstrate that gas stunning was not responsible for the animals′ death. Final pH in breast (6.1 to 6.2) and thigh (6.3 to 6.5) also did not vary among the different stunning methods (P > 0.05). Lightness (L = 60.55) and redness (a = +8.94) values found for breasts from electrical stunning showed that they were darker and redder (P < 0.05), probably due to changes in blood pressure. Glucose and corticosterone levels were not different between gas stunned birds (302.45 to 315.7 mg/dl and 55.71 to 72.49 ng/ml respectively) and birds at rest (305.95 mg/dl and 50.65 ng/ml) (P > 0.05). These stress indicators were higher (337.65 mg/dl for glucose and 104.13 ng/ml for costicosterone) when electrical stunning was used (P < 0.05). Lactate concentrations were lower (5.4 mmol/l) for birds at rest (P < 0.05) but not different for all stunning methods tested (7.3 to 8.1 mmol/l; P > 0.05). These results show that serum glucose may be used as a stress indicator in birds, with the advantage of being a quick and cheap biochemical test. Gas stunning favored birds′ management during slaughter and so reduced workers′ effort and injury hazard and the amount of feces and dust in the room. To make this method available for a large scale process, adjustments in equipments will be necessary to avoid delays in the processing line.

Much has been discussed lately about reusing waste in new construction materials and countless studies have been carried out based on this objective. However, before these products can be called “sustainable” and a recycling system can be effectively implemented, it is fundamental for all the aspects involved in this action to be understood, and more important, what are the true gains for the productive sector and what are the benefits for the environment if this was to occur. In order to obtain a general framework for all environmental aspects and potential impacts associated with these products, over their entire life cycle, the most appropriate methodology is the Life Cycle Assessment (LCA). In view of the above, the objective of this work is to provide an overview of current studies of LCA, its history, its importance, its standards and the methodology employed and its applications related to civil construction. It is expected, to obtain a more complete scenario of the influences from a study of LCA, as well as establishing a contribution for the assessment of specific products and processes for civil construction, disseminating the importance of the use of this tool within the sector.

Within the current context of environmental degradation, primarily caused by unsustainable pat terns of production and consumption (AGENDA 21, 1992), the Protected Areas (PAs) are considered internationally as one of the most successful measures for the conservat ion of biodiversity, according to the Union for the Conservation of Nature (IUCN). The city of Rio Claro (Sao Paulo, Brazi l ) has a significant conservation area in both environmental aspects as historical and cultural, the State Forest 'Edmundo Navarro de Andrade' (FEENA). Beyond the conservation measures, there is a need to develop environmental education that encourages community participation and appreciation in the unit 's maintenance and protection, as well as provide moments of reflection that could conduct perceptual changes, behavioral, attitudinal and evaluative on relations between human beings and their environment . This work brings the proposal to create an interpretive trail in the area of public use of FEENA to contribute to the Unit Management Plan in order to make it an Environmental Education tool. To prepare the planning of the interpretive trail, a deep bibliographic and cartographic review was performed on the subject. It was applied questionnaires in order to know the visitors better and map the features of public visitation, as well as map the visitor preferences about how they would like to receive information on the area and expose field studies in the track site. The trail was traced taking into account the environmental and social aspects, we propose a track suspended above the ground, in order to affect as little as possible and to include the area in the context of PAs people with reduced mobility and visually impaired

The objective of the present work is the construction of percentual indexes of sustainable development "Status" - PIDSD (%) aiming to order and classify the rural settlements, considering agricultural, socioeconomic and environmental aspects, in order to diagnose their sustainable reality. This way, we considered multivariate statistical procedure to establish analytical descriptors - indexes - like the principal components technique (CP). The CP technique was used in a matrix formed by 47 variables observed in 50 rural settlements, distributed in seven different regions of the state of Mato Grosso, obtained from diagnostics, provided by "Mato-Grossense" Enterprise of Research, Assistance and Rural Extension S/A - EMPAER - MT, in order to obtain the indexes used in the construction of PIDSD (%). The settlements with higher PIDSD (%) were considered "higher potential" or "higher sustainable" in relation to the analyzed variables, making the establishment of assistance strategies and cooperation possible, allowing the government and civil society in general, to improve those with worse results ("lower potential" or "lower sustainable"), and search for ways to strengthen and multiply the results of the "higher potential" settlements. Vale do Seringal settlement had the best conditions in relation to the variables, mainly those of higher weigh and was considered the one with "higher potential". São Sebastião had the worst conditions and was considered "lower potential".

Entrepreneurs responsible for the housing project “Vale do Sol III”, (claim of deployment), proposed a technique, in order to resolve conflicts of interest arising in respect Vale do Sol I residents (already implemented). Conflicts taken place in accordance with environmental problems that originated (past) in poor drainage of rainwater from Água Fria stream. This work, based on study case method with deductive approach, analyzed the environmental aspects of the area in order to contribute to the process of sustainable management of medium-sized cities (present), as well as analyzing the prospects for adequate outcome environmental demand (future) . In terms of technical and methodological procedures, was used geoprocessing softwares for the purpose of supporting analysis. It was concluded that, technique proposed at Vale do Sol III enterprise, don’t have necessary, sufficient and satisfactory solution in order to, at least, mitigate the problems of area sustainability. In terms of future prospects, it was concluded that, good sustainable environmental management, with preventive measures, from the point of view of mitigating the environmental and urban conflicts, and corrective measures.

Responsible entrepreneurs responsible for housing project "Vale do Sol III" (claim of deployment) had proposed technique in order to solve conflicts of interest, arising with respect to residents of Vale do Sol I (already implemented). Conflicts gave up due to environmental and urban problems, originated in a notification of responsible concessionaire for the administration of Marechal Rondon highway (entry and exit of people on the road, in the city of Botucatu, Sao Paulo state). This work, based on study case method, within a deductive approach, analyzed urban and environmental aspects of the area in order to contribute to sustainable management of medium-sized cities. There was, moreover, use of GIS software for purpose of supporting this technical analysis. Investigations were carried out within environmental and urban viewpoints about Água Fria watershed, as well as technical and legal basis arising devices both municipal and federal regulations. It was concluded that proposed project of Vale do Sol III, about containment of stormwater and alternative technical and locational traffic, not presented as necessary solution, sufficient and satisfactory in the sense of, at least, mitigate sustainability problems of surrounding area (Água Fria watershed, into which could insert even Vale do Sol I condominium, subject to notification).
