Mapeamento de estudos brasileiros sobre hábitos saudáveis na escola: um recorte dos estudos sobre atividade física e hábitos alimentares

Pesquisas apontam que 15% das crianças brasileiras, entre 5 e 9 anos, são obesas. Os fatores indicados como responsáveis desse cenário são a má alimentação e a falta de exercício físico. Hábitos como alimentação saudável e prática de atividades físicas são, em sua maioria, constituídos na infância, principalmente em crianças com idade escolar e tendem a estender para a vida adulta. Considerando que as crianças passam mais de um terço de sua infância na escola, acredita-se que esse ambiente seja um facilitador para a mudança do comportamento saudável dos alunos. Este estudo tem por objetivo realizar um levantamento de pesquisas sobre aquisição de hábitos saudáveis na escola, mapeando a produção no campo da Educação Física, com ênfase em intervenções sobre atividade física e hábitos alimentares. Foi realizada uma revisão da produção de conhecimentos em teses e dissertações bem como da publicação de artigos em periódicos nacionais e internacionais publicados entre os anos de 2004 até 2014, com os seguintes descritores e variações destes: educação física, hábitos saudáveis, escola. Foram consultadas as seguintes bases de dados: Banco Digital de Teses e Dissertações, Banco de Teses da Capes e Bireme. Com resultado foram encontradas 27 teses e dissertações, sendo apenas sete pertencentes a Educação Física, das quais três apresentavam intervenção. Quanto aos artigos, entre os sete recuperados, apenas dois apresentam intervenções com interfaces nas aulas de Educação Física. Em termos de impacto, os resultados dessas intervenções variam de baixo à efetivo, sendo que apenas um dos trabalhos apresenta um resultado efetivamente positivo. Dessa forma pode-se perceber o baixo número de publicações sobre a temática na área da Educação Física, além da existência de barreiras para um resultado positivo nessas intervenções. As pesquisas apontaram mais barreiras que facilitadores...

Emprego do método eletromagnético (em) na investigação e mapeamento de contaminações geradas por cemitérios: o caso de Monte Alto/SP

The use of geophysical methods in the analysis and mapping of likely contamination plumes has shown a huge value in the development of researches related to environmental issues. Among the main geophysical methods applied to this purpose, the geoelectrical methods stand out, being based on the use of electric and electromagnetic fields. The electromagnetic method (EM) uses physical environment responses created by electromagnetic field propagation, consisting of an alternated electric output and a magnetization force, used to obtain the electric conductivity (σ) of the subsurface materials. It has a broad application in the mineral exploration and prospection, and its use has been also efficient in environmental researches. By the electromagnetic method, this work examined and mapped possible contaminations created by cemetery leachate in the Saudade's Cemetery, located in the city of Monte Alto, Sao Paulo, where sedimentary rocks of the Bauru Group are exposed. Cemetery leachate is a putrefactive liquid, generated from the decomposition of organic matter, which contains substances that can contaminate soil and groundwater. Results achieved in this work show that the use of the electromagnetic method is an important indirect tool in the investigation of environmental contaminations in areas with highly contrasting physical properties

Utilização de análise de agrupamento na caracterização do perfil agrícola e climático da região sudeste do Estado de Mato Grosso

The multivariate analysis grouping was used to characterize the productive and climate profile of southeastern of Mato Grosso state. This technique allowed the junction of similar micro regions from characteristics of productivity and climatic, without the need for the assumption of the number or structure of the groups. Cluster analysis allowed the design of a mosaic of spatial heterogeneity regions. It established different profiles in the composition of groups, joining the more traditional in the culture of a species, or more productive, or those for the development of a particular culture. The results obtained by estimation of the climatic parameters and the multivariate procedures enabled the provision of systematic information that will allow farmers to better decision-making on the competitiveness and maintaining the flow of investment in agricultural sector southeastern Mato Grosso.

Manutenção da diversidade agrícola em assentamentos rurais: um estudo de caso em Moji-Mirim - SP, Brasil

Maintenance of agricultural diversity in rural settlements – a case study in Moji-Mirim, São Paulo, Brazil. This paper investigated whether farmers, when established in rural settlements, keep some traditional features with regard to crops diversity and circulation of planting material. Its aims were to make an ethnobotanical survey of species and varieties and analyze the dinamics of seeds and propagules circulation. A total of 139 varieties of food crops (55 species/28 families) were found, being 87% of them intended for self-consumption; 54% of varieties come from Minas Gerais, home state of most respondents. The number of varieties grown per household ranged from 17 to 54. The informal and free circulation of planting material is the most important way of acquisition. The circulation network is very active, showing a potential for the management of crops diversity, with emphasis on the contribution of settlers to the maintenance and valorization of traditional varieties.

Análise energética na agricultura: ferramenta importante para a produção agrícola mais sustentável

A produção de alimentos e matérias-primas é considerada um dos maiores desafios da atualidade. Assim, os impactos gerados pela atividade da agricultura são muitos, como por exemplo, erosão dos solos, poluição de águas doces e geração de resíduos. Com isso faz-se necessário o desenvolvimento de tecnologias para promover a redução desses impactos. O presente trabalho tem como objetivo apresentar e discutir análises energéticas em sistemas de produção agrícola como uma ferramenta capaz de destacar a dependência dos agroecossistemas de energia externa e de fontes não renováveis, particularmente de fontes fósseis. Assim, com o uso dessa ferramenta, alternativas para uma produção agrícola com menos impacto ambiental pode ser alcançada, proporcionando a ampliação das possibilidades para uma produção mais sustentável.

Consumo de combustível de um trator agrícola em função do tipo de soloe da pressão de inflação nos pneus utilizando o equipamento canteirador

Agricultural mechanization improved the efficiency of field operations by providing an increase in crop production. The intensified mechanization, however, has led to higher energy use mainly in the area of fuel consumption. The objective of this study was to compare the fuel consumption of tractors using two different tire pressures for two different types of soil during tillage with irrigated cotton in semi-arid regions. These tests were performed at the Maricopa Agricultural Center (MAC), an experimental farm belonging to The University of Arizona with a Case 4x2 TDA 88kW equipped with an autopilot system. The results showed lower fuel consumption using a tire pressure of 124 kPa on sandy clay loan soil.

Consumo de combustível de um trator agrícola no preparo do solo para a cultura do algodão irrigado em função da pressão de inflação nos pneus

Currently, the efficiency in field operations and the increased productivity of crops is only possible with the use of agricultural machinery and equipment. This intensification of mechanized activities in agriculture, however, led to higher energy costs on farms mainly in the fuel consumption of agricultural tractors. The objective was to compare the fuel consumption of a tractor on tillage operations for irrigated cotton in semi-arid region varying two tire inflation pressures. The tests were conducted in Maricopa Agricultural Center (MAC), an experimental farm belonging to The University of Arizona using a 4x2 TDA Case tractor equipped with a 88kw autopilot system. The results showed lower values in the hourly fuel consumption by using the minimum tire inflation pressure of 124 kPa for all tillage equipment used.

Geoprocessamento aplicado na determinação das áreas de preservação permanente e áreas de conflito com cultivo agrícola no município de Lençóis Paulista/SP

The city of Lençóis Paulista has a great part of its agricultural land cultivated by sugar cane and reforestation of eucalyptus and pine trees. In the county there are industries that exploit energy extracted from energy cogeneration. The city of Lençóis Paulista, in recent years, has been demonstrating considerable levels of economic and social growth with the industries that are working with sugarcane and eucalyptus mainly responsible. However, the expansion of agricultural land in many cases does not take into consideration the permanent preservation areas that are protected by the law. The APP's are of fundamental importance in the management and conservation of the environment preserving the natural plants and wildlife, and also preventing erosion and the silting of drainage networks. This objective of this study was to diagnose land use, analyze if Permanent Preservation Areas are regulated to the Brazilian Forestry Code (1965) and also diagnose areas of conflict. In relation to the use and occupation of land, the research has shown how the land is divided (agricultural crops and urban zones), and highlighted areas of conflict with the Permanent Preservation Areas. All of the information is contained in maps using Geographic Information Systems. However, it has become clear that environmental laws are not respected as much in urban areas as they are in rural areas. The PPA's are virtually nonexistent, thus creating damage to the environment and local population.
