Proposta para a implantação de uma trilha interpretativa com bases na Pedagogia Waldorf na Floresta Estadual Edmundo Navarro de Andrade - Rio Claro, SP

At a time when people turn increasingly to technological innovations and virtual networks, a closer interaction with the environment can provide sensitizing experiences. One tool that facilitates this approach is the interpretative trail: its use in a Unit of Conservation (UC) allows more contact between the visitor and the nature elements. This research aimed to propose the establishment of an interpretative trail at the State Florest “Edmundo Navarro de Andrade” (FEENA) in Rio Claro (SP) with theoretical bases from Waldorf Pedagogy. The proposed trail is destined for students with 07-14 years-old, a period that the awareness is more accurate in a person, according to Waldorf tenets. On the path of the trail, we propose some educational activities at the points of interpretation: storytelling about environment; “photograph” the place with a drawing; create a song with sounds produced by the body and by nature elements; blindfold guide and a circle of people to share experiences. The activities aim to provide in the student a close and harmonious contact with oneself, with other people and with the natural world, and also serve as a support for programs of public use and environmental education at UC. The environmental awareness process in the context of FEENA - which has a significant landscape valuation - develops through the sensibilities of exterior and interior world. And also develops with the creation if images, thoughts, feelings and interdependencies relationships. Therefore, the ecologic education allows changes and formation of values and sensitive attitudes to students about the environment

Life cycle assessment applied to municipal solid waste management: a case study

This study analyzes the environmental performance of the Municipal Solid Waste Management System (MSWMS) of Piedade, São Paulo, from a systemic perspective. A life cycle assessment (LCA) technique was applied according to an attributional approach to evaluate both the current operational situation and different prospective scenarios, which were devised based on the application of targets for recycling dry and wet waste suggested by the pre-draft version of the Brazilian Plan for Solid Waste. The life cycle impact assessment method EcoIndicator 99, in association with normalization and weighting procedures, was used to conduct the analysis. It was observed that the adoption of goals of 30%, 50% and 70% for recovering of the recyclable dry waste, resulted in improvement of the environmental performance of the waste management system under analysis, respectively of 10%, 15% and 20%. It was also possible to detect an evolution in the order of 54% in reducing impacts resulting from the adoption of targets for composting. LCA proved to be effective for the evaluation of the environmental performance of MSWMS-Piedade. However, for future evaluations, the attributional approach should be replaced by the methodological practice of substitution to enable the avoided burdens to be considered in estimations of the environmental performance municipal solid waste management systems.

Assoreamento de lago integrante da sub-baciado Córrego da Cascata, Botucatu, SP: implicações morfométricas

The watershed is considered a unit of territorial study, planning and land management, and is molded by the local geologic conditions and climate. Thus, this study aimed to assess the morphometric features of the subwatershed of Cascata Stream, in Botucatu (SP), and their implications for the siltation process in a lake. The assessment included indexes generated from data calculated by means of a digitalized cartographic basis georeferenced on the 1:10,000 scale using the software AutoCad map 2004. The software Quantum GIS 1.8 was also employed to generate the digital elevation model (DEM) and the map of declivities which led to the mean declivity (Dm) of the subwatershed. According to the indexes form factor (Kf), sinuosity (Is), circularity (Ic) and compacity coefficient (Kc), the subwatershed had elongated form, low propensity to floods and rapid flow. The draining density (Dd) and relief ratio (Rr) indicated more efficient mean drainage, favoring higher desiccation and mean erosive stage. The roughness coefficient (Cr) indicated that this subwatershed is suited to agriculture. The anthropic intervention at the watershed dividing line is the major factor for sediment carrying in the lake and compromises not only the landscape beauty, but also the aquatic life of this ecosystem.

Medium Light and Medium Roast Paper-Filtered Coffee Increased Antioxidant Capacity in Healthy Volunteers: Results of a Randomized Trial

We compared the effects of medium light roast (MLR) and medium roast (MR) paper-filtered coffee on antioxidant capacity and lipid peroxidation in healthy volunteers. In a randomized crossover study, 20 volunteers consumed 482 +/- 61 ml/day of MLR or MR for four weeks. Plasma total antioxidant status (TAS), oxygen radical absorbance capacity (ORAC), oxidized LDL and 8-epi-prostaglandin F2 alpha, erythrocyte superoxide dismutase (SOD), glutathione peroxidase (GPx), and catalase (CAT) activity were measured at baseline and after the interventions. MLR had higher chlorogenic acids-(CGA; 334 mg/150 mL) and less caffeine (231 mg/150 ml) than MR had (210 and 244 mg/150 ml, respectively). MLR also had fewer Maillard reaction products (MRP) than MR had. Compared with baseline, subjects had an increase of 21 and 26 % in TAS, 13 and 13 % in CAT, 52 and 75 % in SOD, and 62 and 49 % in GPx after MLR and MR consumption (P < 0.001), respectively. ORAC increased after MLR (P = 0.004). No significant alteration in lipid peroxidation biomarkers was observed. Both coffees had antioxidant effects. Although MLR contained more CGA, there were similar antioxidant effects between the treatments. MRP may have contributed as an antioxidant. These effects may be important in protecting biological systems and reducing the risk of diseases related to oxidative stress.

Premotor and occipital theta asymmetries as discriminators of memory- and stimulus-guided tasks

The saccadic paradigm has been used to investigate specific cortical networks involving visuospatial attention. We examined whether asymmetry in theta and beta band differentiates the role of the hemispheres during the execution of two different prosacadic conditions: a fixed condition, where the stimulus was presented at the same location; and a random condition, where the stimulus was unpredictable. Twelve healthy volunteers (3 male; mean age: 26.25) performed the task while their brain activity pattern was recorded using quantitative electroencephalography. We did not find any significant difference for beta, slow- and fast-alpha frequencies for the pairs of electrodes analyzed. The results for theta band showed a superiority of the left hemisphere in the frontal region when responding to the random condition on the right, which is related to the planning and selection of responses, and also a greater activation of the right hemisphere during the random condition, in the occipital region, related to the identification and recognition of patterns. These results indicate that asymmetries in the premotor area and the occipital cortex differentiate memory- and stimulus-driven tasks. (C) 2011 Elsevier Inc. All rights reserved.

Analysis of slow- and fast-alpha band asymmetry during performance of a saccadic eye movement task: Dissociation between memory- and attention-driven systems

This study aimed at analyzing the relationship between slow- and fast-alpha asymmetry within frontal cortex and the planning, execution and voluntary control of saccadic eye movements (SEM), and quantitative electroencephalography (qEEG) was recorded using a 20-channel EEG system in 12 healthy participants performing a fixed (i.e., memory-driven) and a random SEM (i.e., stimulus-driven) condition. We find main effects for SEM condition in slow- and fast-alpha asymmetry at electrodes F3-F4, which are located over premotor cortex, specifically a negative asymmetry between conditions. When analyzing electrodes F7-F8, which are located over prefrontal cortex, we found a main effect for condition in slow-alpha asymmetry, particularly a positive asymmetry between conditions. In conclusion, the present approach supports the association of slow- and fast-alpha bands with the planning and preparation of SEM, and the specific role of these sub-bands for both, the attention network and the coordination and integration of sensory information with a (oculo)-motor response.

Alpha-band power in the left frontal cortex discriminates the execution of fixed stimulus during saccadic eye movement

Introduction: The saccadic paradigm has been used to investigate specific cortical networks involving attention. The behavioral and electrophysiological investigations of the SEM contribute significantly to the understanding of attentive patterns presented of neurological and psychiatric disorders and sports performance. Objective: The current study aimed to investigate absolute alpha power changes in sensorimotor brain regions and the frontal eye fields during the execution of a saccadic task. Methods: Twelve healthy volunteers (mean age: 26.25; SD: +/- 4.13) performed a saccadic task while the electroencephalographic signal was simultaneously recorded for the cerebral cortex electrodes. The participants were instructed to follow the LEDs with their eyes, being submitted to two different task conditions: a fixed pattern versus a random pattern. Results: We found a moment main effect for the C3, C4, F3 and F4 electrodes and a condition main effect for the F3 electrode. We also found interaction between factor conditions and frontal electrodes. Conclusions: We conclude that absolute alpha power in the left frontal cortex discriminates the execution of the two stimulus presentation patterns during SEM. (C) 2012 Elsevier Ireland Ltd.
