A contribuição da educação ambiental para uma compreensão ética da relação entre indivíduos humanos e cães: inferências teóricas a partir de um estudo de caso no município de Rio Grande-RS

A presente pesquisa teve como problemática o cão abandonado, e fez a relação entre esta situação e os processos humanos e culturais que perpassam o problema. A questão central da pesquisa é: Como compreender a relação dos humanos com os cães, e como a Educação Ambiental pode contribuir para a construção da reflexão sobre o tema e a consequente mudança de postura dos humanos para com estes animais em seu convívio social? O foco da pesquisa é a ética entendida como ética da vida a partir de autores como Morin, Singer e Brugger. O objetivo da pesquisa é contribuir para a construção de uma nova mentalidade; fazer perceber uma ética que não está clara, e buscar compreender os processos que afastem os humanos desta mentalidade. Sendo assim, a fundamentação teórica concentra - se em estudos sobre a ética, a domesticação e o antropocentrismo. Justifico este trabalho por tratar de uma situação degradante para com a vida deste animal, por seu valor intrínseco, e por ser um animal que, em minha opinião, acompanhou e refletiu a própria história da humanidade. A metodologia utilizada foi o Estudo de Caso, aplicado na cidade de Rio Grande, entre 2011 e 2013, e contou com entrevistas com grupos de proteção animal, e com o atual prefeito municipal. Como ferramenta metodológica, para a realização da pesquisa e do texto, utilizei a Mandala Reflexiva, da Prof. Dra. Virginia Machado, que é uma configuração de abordagem pedagógica e epistemológica do processo de investigação. A interação da pesquisa, além do resultado da atividade com alunos jovens e adultos da 8ª série do PROMEJA de uma escola municipal, envolveu a proposta da produção de vídeos amadores de sensibilização sobre o tema, para ser aplicada em escolas ou em quaisquer tipos de projetos com interessados sobre o tema, a fim de difundir a questão a partir da experiência ético - estética. O resultado prático é o registro de uma nova expectativa em relação à resolução do problema dos cães abandonados nesta cidade. Filosoficamente, chegou - se a uma reflexão complexa sobre o ser humano e suas ações no planeta, que indicam que, quanto mais formos capazes de pensar no todo, e substituir o egoísmo por uma dosagem de altruísmo e de ética, mais sentido terá a nossa própria vida.

Diversidade de macroalgas marinhas bentônicas dos recifes de Maracajaú, área de preservação ambiental dos recifes de corais, Rio Grande do Norte, Brasil

Despite the importance of coral reefs to humanity, these environments have been threatened throughout the world. Several factors contribute to the degradation of these ecosystems. The Maracajaú Reef Complex, in Rio Grande do Norte state is part of the Coral Reefs Environment Preservation Area in northeastern Brazil. This area has been receiving an increasing influx of tourism and the integrity of the local reefs is a matter of concern. In this study, the reef macroalgae communities were studied and compared within two areas distinguished by the presence or absence of tourism activities. Two sample sites were chosen: the first one, where diving activities are intense; and the other, where these practices do not occur. Samples were collected at both sites within a quadrate of 625 cm2 of area randomly thrown 5 times along a 10 meters transect line. Richness, Shannon-Hill diversity and Simpson dominance indices were determined based on biomass data. Similarity between sites was analyzed with Bray-Curtis similarity and distance index. Fifty-eight macroalgae species were observed, including 7 Chlorophyta, 13 Phaeophyta and 38 Rhodophyta. In the non-disturbed site, 49 species were found, while at the disturbed site, there were 42 species. Dictyotaceae and Corallinaceae were the most representative families at the non-disturbed site, and Rhodomelaceae and Dictyotaceae at the disturbed site. The non-disturbed site presented a higher biomass and the greatest richness and diversity indices. In the disturbed site the dominance index was greater and Caulerpa racemosa was the dominant species. The dendogram based on similarity index showed two major clusters, and an isolated element at the center that corresponds to a sample from the disturbed site. In the first cluster, samples from the non-impacted site were predominant and fleshy brown algae were more conspicuous. The second cluster was composed primarily of samples from the impacted site, where C. racemosa and red filamentous and erect calcareous algae associations (turf forming) were observed covering large extensions. These associations are represented by groups of algae adapted to environments where disturbances are frequent. They can grow rapidly on substrate where benthic community was removed and do not allow the establishment of other species. The results of the present study show that tourism activity is an impacting factor that has been causing shifts in macroalgae communities in the Maracajaú Reef Complex

Can we predict agitation in patients with suicide attempts in the emergency department?

Background: The agitation in patients presenting to the emergency department (ED) after suicide attempts is common and an important problem. Objective: To establish whether we can predict agitated patients among suicide attempt patients in ED. Methods: This is a cross-sectional observational study of adult suicide attempt events in ED. Information was collected prospectively on a specially designed data-collection form. Patients aged 16 years old and above who presented to the ED for care due to suicide attempts were included in the study. Suicide attempts were grouped as aggressive and non-aggressive attempts. Results: A total of 533 patients were included. Forty-three of these patients had agitation in ED (8%). Non-aggressive suicide attempts were referred to psychiatry services more than aggressive ones (73.6%, n=345 vs 32.8%, n=21, P<0.0001). Agitation in ED and being male increased aggressive suicide attempt risk 3.5 (95% CI:1.6-7.6) and 3.2 times (95% CI:1.8-5.5), respectively. Agitation was statistically more frequent among these patients: those on antidepressant overdose, with previous suicide attempt; with aggressive suicide attempt; and those with confusion; and unconsciousness (P<0.05). Conclusion: Patients who attempted suicide and whose risk of harm to others included those with: antidepressant overdose, aggressive suicide attempt and the unconscious. Response teams should be prepared for these subgroups.

Compartimentação fisiográfica para análise ambiental do potencial erosivo a partir das propriedades da rede de drenagem

O presente trabalho teve como objetivo compartimentar a sub-bacia do Baixo Rio Piracicaba - SP, em unidades homogêneas quanto à potencialidade à erosão visando a subsidiar o gerenciamento ambiental. A importância desta pesquisa concentra-se no intenso desenvolvimento dos processos erosivos na área em foco e na sua importância socioeconômica em níveis estadual e nacional. O procedimento adotado para atingir o objetivo foi a análise da rede de drenagem e dos lineamentos obtidos pelas imagens TM/Landsat-5. O resultado obtido foi a divisão da área em quatro compartimentos quanto à potencialidade à erosão: muito alta, alta, média e baixa. Concluiu-se que a área estudada é heterogênea, com regiões sujeitas a diferentes intensidades de processos erosivos e que a sistemática adotada se mostrou eficiente para caracterizar as compartimentações fisiográficas da potencialidade erosiva, e essas compartimentações podem e devem ser utilizadas como ponto de partida para estudos ambientais e de utilização do território, em consonância com o desenvolvimento sustentável.

Clinical effect of intravenous thrombolysis combined with nicorandil therapy in patients with acute ST-segment elevation myocardial infarction

Purpose: To evaluate the effectiveness of intravenous thrombolysis in combination with nicorandil in the treatment of acute ST-segment elevation myocardial infarction (STEMI). Methods: Patients who developed acute STEMI and underwent intravenous thrombolysis in the hospital were selected and divided into observation group (n = 128) and control group (n = 114). Besides thrombolytic therapy, the observation group was also given 20 mg of nicorandil. The control group received conventional thrombolytic therapy only. Clinical effects and rehabilitation of patients were observed. Results: Cardiac troponin I (cTNI) level of the observation group was 4.0 ± 1.5, 8.3 ± 2.8 and 9.8 ± 3.9 after 4, 12 and 24 h, respectively, which is much lower than 5.8 ± 1.4, 11.4 ± 2.7 and 13.2 ± 4.2 in the control group (p < 0.05). ST-segment resolution of observation group was higher (44 ± 14, 52 ± 17, 69 ± 21 and 80 ± 18) % at different time points, compared with the control group (p < 0.05). The proportion of patients with Curtis-Walker score > 3 points, and ventricular wall motion score (4.70 %; 1.38 ± 0.11) in the observation group were both lower than those of the control group (21.00 %; 1.43 ± 0.15) (p < 0.05). The difference in adverse cardiac events between the observation group (N = 6, 4.70 %) and control group (N = 12, 10.50 %) was not statistically significant (p > 0.05) Conclusion: Combining intravenous thrombolysis with nicorandil therapy can enhance myocardial perfusion level, reduce myocardial damage, improve cardiac function and decrease risk of arrhythmia for acute STEMI patients.

Caracterização batimétrica e fisicooceanográfica do canal de acesso ao porto de Cabedelo/PB: uma análise ambiental ao derrame de óleo

The State of Paraíba is one of the most dynamic states of Brazil, strategically located in the northeast, is notable for the excellent potential for integration of different transportation modes forming the states of Rio Grande do Norte, Pernambuco and Alagoas. The dynamic that occurs with port activity causes changes in the space where it is installed. And the elements of this space are always more than suffering direct or indirect influences as the flow in the port is expanded. Therefore, this region became subject to the accidental spillage of oil, because it presents a heavy traffic of ships of various sizes that can run aground or collide with oil causing accidental events. The study of geomorphological and sedimentological compositions of seafloor becomes important as more is known about the relationships between these parameters and associated fauna, and can identify their preferred habitats. The database background, acoustically collected along the proposed study area, is a wealth of information, which were duly examined, cataloged and made available. Such information can serve as an important tool, providing a geomorphological survey of the sedimentary area studied, and come to subsidize, in a flexible, future decision making. With the study area Port of Cabedelo, Paraíba - Brazil, this research aimed to evaluate the influence of the tidal surface and background in modeling the seabed, including the acquisition of information about the location of submerged rocky bodies and the depth of these bodies may turn out to be natural traps for the trapping of oil in case of leaks, and obtain the relationship between types of bed and the hydrodynamic conditions present in the region. In this context, for this study were collected bathymetric data (depth) and physical oceanographic (height of water column, water temperature, intensity and direction of currents, waves and turbidity), meteorological (rainfall, air temperature, humidity, winds and barometric pressure) of the access channel to the Port of Cabedelo / PB and its basin evolution (where the cruise ships dock), and includes tools of remote sensing (Landsat 7 ETM +, 2001), so that images and the results are integrated into Geographic Information Systems and used in the elaboration of measures aimed at environmental protection areas under the influence of this scale facilities, serving as a grant to prepare a contingency plan in case of oil spills in the region. The main findings highlight the techniques of using hydroacoustic data acquisition together bathymetric surveys of high and low frequency. From there, five were prepared in bathymetric pattern of Directorate of Hydrography and Navigation - DHN, with the depth in meters, on a scale of 1:2500 (Channel and Basin Evolution of Access to Port of Cabedelo), where there is a large extent possible beachrocks that hinder the movement of vessels in the port area, which can cause collisions, running aground and leaking oil. From the scatter diagram of the vectors of currents, it can be seen as the tidal stream and undergoes a channeling effect caused by the bidirectional effect of the tide (ebb and flood) in the basin of the Port of Cabedelo evolution in NW-direction SE and the highest speed of the currents occurs at low tide. The characterization weather for the period from 28/02 to 04/07/2010 values was within the expected average for the region of study. The multidisciplinary integration of products (digital maps and remote sensing images), proved to be efficient for the characterization of underwater geomorphological study area, reaching the aim to discriminate and enhance submerged structures, previously not visible in the images

DOING MORE WITH SHORT PERIOD DATA: DETERMINING MAGNITUDES FROM CLIPPED AND OVER-RUN SEISMIC DATA AT MOUNT ST. HELENS

How can we calculate earthquake magnitudes when the signal is clipped and over-run? When a volcano is very active, the seismic record may saturate (i.e., the full amplitude of the signal is not recorded) or be over-run (i.e., the end of one event is covered by the start of a new event). The duration, and sometimes the amplitude, of an earthquake signal are necessary for determining event magnitudes; thus, it may be impossible to calculate earthquake magnitudes when a volcano is very active. This problem is most likely to occur at volcanoes with limited networks of short period seismometers. This study outlines two methods for calculating earthquake magnitudes when events are clipped and over-run. The first method entails modeling the shape of earthquake codas as a power law function and extrapolating duration from the decay of the function. The second method draws relations between clipped duration (i.e., the length of time a signal is clipped) and the full duration. These methods allow for magnitudes to be determined within 0.2 to 0.4 units of magnitude. This error is within the range of analyst hand-picks and is within the acceptable limits of uncertainty when quickly quantifying volcanic energy release during volcanic crises. Most importantly, these estimates can be made when data are clipped or over-run. These methods were developed with data from the initial stages of the 2004-2008 eruption at Mount St. Helens. Mount St. Helens is a well-studied volcano with many instruments placed at varying distances from the vent. This fact makes the 2004-2008 eruption a good place to calibrate and refine methodologies that can be applied to volcanoes with limited networks.

¬FISH DISTRIBUTIONS IN LAKE ONTARIO’S EASTERN BASIN AND THE UPPER ST. LAWRENCE RIVER: AN ANALYSIS USING GIS AND OCCUPANCY MODELLING TECHNIQUES

Predictive models of species distributions are important tools for fisheries management. Unfortunately, these predictive models can be difficult to perform on large waterbodies where fish are difficult to detect and exhaustive sampling is not possible. In recent years the development of Geographic Information Systems (GIS) and new occupancy modelling techniques has improved our ability to predict distributions across landscapes as well as account for imperfect detection. I surveyed the nearshore fish community at 105 sites between Kingston, Ontario and Rockport, Ontario with the objective of modelling geographic and environmental characteristics associated with littoral fish distributions. Occupancy modelling was performed on Round Goby, Yellow perch, and Lepomis spp. Modelling with geographic and environmental covariates revealed the effect of shoreline exposure on nearshore habitat characteristics and the occupancy of Round Goby. Yellow Perch, and Lepomis spp. occupancy was most strongly associated negatively with distance to a wetland. These results are consistent with past research on large lake systems indicate the importance of wetlands and shoreline exposure in determining the fish community of the littoral zone. By examining 3 species with varying rates of occupancy and detection, this study was also able to demonstrate the variable utility of occupancy modelling.
