Conhecimento de Acadêmicos de Enfermagem Frente à Parada Cardiorrespiratória
Authors: Gomes Juliana Araújo Pereira , Braz Márcia Ribeiro
Published: March 2021

Vítimas que sofrem uma parada cardíaca e ficam sem assistência adequada por mais de 3 minutos podem evoluir para um prognóstico ruim, chegando até a morte. A reanimação cardiopulmonar é um conjunto de procedimentos que aprendemos durante a graduação em enfermagem, porém, não é muito aprofundado o tema durante as aulas, devido à especificidade da grade curricular, que aponta para um curso generalista. Este estudo propõe como objetivo identificar o conhecimento de acadêmicos graduandos em enfermagem sobre a atuação do enfermeiro em casos de parada cardiorrespiratória. Trata-se de uma pesquisa de natureza qualitativa descritiva e contou com a participação de acadêmicos de um Curso em Enfermagem da região serrana do Rio de Janeiro, sendo utilizado um questionário estruturado para avaliação das manobras de ressuscitação cardiopulmonar. Concluímos que poucos discentes da Instituição pesquisada saberiam o que fazer diante de uma vítima de PCR, apesar de estarem próximos á a conclusão do curso. Observamos que, apesar do conteúdo teórico e prático sobre PCR ser oferecido em algumas disciplinas, ao final do curso, o discente ainda sai com essa lacuna em sua formação. O futuro enfermeiro, ao sair da faculdade, deve estar apto a auxiliar e identificar problemas de saúde em situação de risco e fazer sucessivas reavaliações posteriores conforme as mudanças apresentadas no quadro do paciente, visando sempre rapidez e sincronismo com a equipe para uma melhor assistência prestar.
Implementation of Subsidized Fuel Policy in Gorontalo City
Authors: Sakbir Sakbir , Idji Rusly Abdurahman
Published: March 2021

This study aims to determine the implementation of the subsidized fuel oil (BBM) policy in Gorontalo City. The method used in this research is descriptive qualitative. Data collection techniques used interview techniques and focus group discussion (FGD). The results showed that the communication of the implementation of the subsidized fuel policy in the city of Gorontalo was well implemented. The socialization was carried out through coordination with all relevant stakeholders, the unfolding of notification banners related to the Subsidized Fuel policy at each gas station point. Resources, in order to support the implementation of the subsidized fuel policy in Gorontalo City, are not sufficient. It can be seen from the minimal number of gas stations that distribute subsidized fuel and the low volume of fuel supplied for each subsidized fuel. The attitude of the implementer/disposition towards the subsidized fuel policy in Gorontalo City is not very good. It can be seen from the attitude of the government and other stakeholders that they do not care about the distribution of subsidized fuel to non-target groups, as in this case it is given to retailers only. The bureaucratic structure does not work optimally, it can be seen from the absence of officers from either the government, Pertamina or other stakeholders at each gas station point who should be in charge of controlling and supervising the distribution of Subsidized Fuel.

Published: March 2021

En el mundo se han desarrollado en el sector agropecuario tecnologías innovadoras que como principal meta aumentar la calidad de los productos y aumentar el volumen, actualmente uno de los objetivos más importantes, es el cuidado del medio ambiente y el consumo de alimentos sanos. La principal innovación de este proyecto son los cultivos hidropónicos en módulos para poder cultivar hortalizas en espacios pequeños de las casas (traspatio). Estos cultivos tienen la ventaja de producir cosechas en un menor tiempo. Por lo anterior, se planeó implementar el uso de módulos en traspatio para cultivo de hortalizas con mayor demanda en la zona de Tuxpan, Veracruz. Se realizaron encuestas tomando en cuenta sólo a la población económicamente activa de un rango de edades de 18 a más de 40 años, obteniendo un tamaño de muestra de 382 personas a encuestar, el objetivo de las encuestas fue principalmente determinar el tipo de hortalizas que tienen mayor demanda y el tipo de módulos que los ciudadanos estarían dispuestos a adquirir para producir sus hortalizas para propio consumo y/o comercialización. Los resultados que se obtuvieron mostraron: que de las 382 personas encuestadas, se confirmó el consumo de hortalizas por 1135 personas más; los sitios preferidos para adquirir las hortalizas son las tiendas pequeñas locales y el mercado; las hortalizas que tienen mayor demanda son tomate, tomate verde, chile, cebolla, cilantro, calabacita, acelgas, espinacas, lechuga, papa ajo, rábanos, zanahoria, brócoli, frijol, coliflor, epazote y berenjena; las principales causas de consumo de hortalizas son por salud y nutrición; el 47% de la población tiene noción de técnicas de hidroponía, afirma que consumirían productos cultivados bajo dicha técnica, les gustaría tener su propio módulo hidropónico y le gustaría adquirir el paquete tecnológico; y finalmente, a 336 personas encuestadas estarían interesado en adquirir algún módulo hidropónico, de los cuales sólo 186 están dispuestos a pagar un valor de $1000.00 a $3000.00 pesos.

Published: March 2021

El manglar es un ecosistema complejo y dinámico, considerado un humedal de importancia internacional ya que posee una fuerte interrelación inter/intra específica con el medio. Su importancia radica en innumerables servicios que brindan a distintos ámbitos, incluyendo el económico. Sin embargo, pese a esto, los manglares han sido impactados negativamente por la contaminación, teniendo una tasa anual de deforestación de aproximadamente 2.5%, pasando de 775 mil ha en 2005 a 764 mil 486 ha en 2010. El objetivo de esta investigación fue establecer dos zonas del sitio Ramsar 1602 “Manglares y Humedales de Tuxpan”, una al norte y otra al sur (ZN y ZS), de una hectárea de superficie cada una. Dentro de los principales contaminantes del área se encuentran efectos del turismo, infraestructura carretera y petrolera, actividades agropecuarias y marícolas, la reducción del flujo de agua por obras de riego y contaminación de las aguas por agroquímicos, metales pesados, nutrimentos e hidrocarburos asociados a varias actividades, principalmente en la zona norte. Se evaluaron concentraciones de hidrocarburos fracción pesada (HFP) en 16 submuetras de los dos áreas obtenidas a una profundidad de 70 cm de la superficie para obtener una muestra compuesta por cada zona, la cual fue analizada (EPA 1661a y 9071b con algunas modificaciones), cuantificando los HFP por diferencia de peso. Se encontraron hidrocarburos fracción pesada en ambas zonas de muestreo, con la mayor concentración en la zona norte, sin embargo, las concentraciones no fueron estadísticamente diferentes.

Published: March 2021

En el presente trabajo se determinó la presencia y concentraciones de los pesticidas organoclorados (PO), en agua y sedimentos de Laguna de Metztitlán, Hidalgo; con el objetivo de identificar el uso de estos compuestos como un factor de presión sobre la biodiversidad y un potencial de riesgo asociado a la salud, problemática que se acentúa debido a que inmerso en la reserva hay asentamientos humanos y que la principal actividad económica de la región es la agricultura. Para su evaluación se tomaron cinco muestras compuestas de agua en la Laguna de Metztitlán en el 2016 y una en la desembocadura del Río Metztitlán, tanto en época de sequía como de lluvia, bajo los lineamientos de la NMX-AA-003-1980. Se analizaron de manera individual por triplicado por cromatografía de gases y espectrofotometría de masas. Los resultados corroboran lo reportado bibliográficamente, además de que a las concentraciones observadas hay un potencial de riesgo para la salud y la biodiversidad, lo cual implica la necesidad de monitorear la zona permanentemente para evaluar la presencia y concentración de estos compuestos, así como su potencial impacto en el ambiente y en la población.

O artigo discute sobre o processo histórico da questão agrária no Brasil, abordando a política agrária como processo de consolidação do capitalismo no campo, partindo do pressuposto econômico como determinação da dominação política e social. O objetivo é analisar os elementos que desencadearam a constituição das políticas agrárias na Amazônia brasileira, alinhadas ao modo de produção capitalista e à reforma agrária de mercado, alicerçada em políticas públicas pautadas na plataforma neoliberal para manutenção da estrutura do capitalismo no campo. A metodologia utilizada é de caráter bibliográfico no viés do materialismo histórico com teóricos que discutem a política de reforma agrária e o capitalismo, além do uso de dados estatísticos secundários. Os resultados evidenciam que o processo histórico agrário se consolidou nas bases do capitalismo dependente atendendo aos interesses do grande capital, fatores que contribuíram para sustentação da estrutura fundiária na Amazônia, cujo destaque é a concentração de terras, a exploração e a dominação.Como citar este artigo:FEITOSA, Osmiriz Lima; OLIVEIRA, Selma Suely Baçal de.

Review on Buildings Health Monitoring System by Using Hybrid Data Optimization Based on Machine Learning Algorithm
Authors: Shenmare Shweta D
Published: March 2021

The detection of cracks is a crucial task in monitoring structural health and ensuring structural safety. The manual process of crack detection is pains takingly time-consuming and suﬀers from subjective judgments of inspectors. This study establishes an intelligent model based on image processing techniques for automatic crack recognition and analyses. In the new model, a gray intensity adjustment method, called Min-Max Gray Level Discrimination (M2GLD), is proposed to preprocess the image thresholded by the Otsu method. The goal of this gray intensity adjustment method is to meliorate the accuracy of the crack detection results. Experimental results point out that the integration of M2GLD and the Otsu method, followed by other shape analysis algorithms, can successfully detect crack defects in digital images. Therefore, the constructed model can be a useful tool for building management agencies and construction engineers in the task of structure maintenance.

Authors: Haisley Phillip , Grandorff Catherine , Agbonlahor Osasohan , Mendez Sylvia , Hansen Mandy
Published: March 2021

Globally, collegiate students possess distinct drives, opportunities, and constraints that influence their choices regarding if, when, and where to study abroad. This research explored the study abroad motivations of US students who were studying in other countries as well as international students who were studying in the US. Data was collected using a cross-sectional survey constructed from pre-existing study abroad motivation instruments. Human capital theory and the push-pull model of international education flow were used as the theoretical frameworks grounding this study’s survey. A principal components analysis helped determine the most parsimonious number of latent motivation constructs in the survey. Using independent samples t-tests, significant differences were found in motivations related to language learning, academic enrichment, avoiding social limitations, and aspiration to work in host country; these factors were significantly higher among international students as compared to US students. An ordinary least squares (OLS) regression analysis found that when holding all other independent variables constant, international student status significantly predicted language learning as a study abroad motivation. This study’s results offer insight on how colleges and universities can craft global experiences suited to students’ desires to study outside their home country. It also brings awareness to the role of country of origin in motivational factors when studying abroad and encourages stakeholders to consider the importance of cultural and national background when engaging students in these opportunities.

IDENTIFICATION OF UNORGANIZED WORKERS: A STEP PRIOR TO SOCIAL SECURITY
Authors: Vijayvargiya Harshita
Published: March 2021

The Union Government with its aim to provide optimum benefits of Social schemes is trying to cover the unorganized workers under an umbrella of unique numbers for their identification. But, the identification of the unorganized workers is still lingering in uncertainties. The main focus of this research paper is on understanding the attempts made by different stakeholders in identifying the unorganized workers. The attempts may be termed bizarre as they have completely mixed two different concepts – the informal sector and unorganized workforce. Social Workers can be efficiently trained to help the Government in identifying unorganized workers. A policy specifically dealing with the unorganized workers including their identification, their needs, and mechanism to deliver services is need for the hour. Employment rate or number can’t be a foundation to define or describe the worker as unorganized.

Authors: Nita Dea Refika , Anwarudin Oeng , Nazaruddin Nazaruddin
Published: March 2021

Farmer regeneration is an effort to maintain and increase the number of farmers who have decreased. One of the programs to attract young generation in agriculture is Sustainable Food House Areas (SFHA) activities. The purposes of this study are to describe the level of youth interest, analyse factors that decide the interest, and formulate some strategies for developing youth interest in SFHA activities. This study was conducted in Sukatani, Sukaraja Sub-district, Bogor Regency in April â€“ June 2020. This study used 50 peoples which determined using simple random sampling technique. The variables consist of individual characteristics, external factors, and youth interest in SFHA activities. Data analysis that used in this study is a descriptive analysis, correlation Rank Spearman analysis, and SWOT analysis. The results showed 52% of youth respondents had a high interest in SFHA activities. The factors that decide youth interest in SFHA activity are ICT access, cosmopolitan behavior, motivation, and some external factors. The strategies that can be undertaken to develop youth interest in SFHA activities are external factors support (family support, agricultural extension, community support and natural resources) to overcome the weaknesses (ICT access and cosmopolitan). Efforts that can be made are information media supply as a reference for youth generation in both of printed or electronic media, and actively conducting training and agricultural extension as a form of SFHA development.

Regulation of microRNA-33, SREBP and ABCA1 genes in a mouse model of high cholesterol
Authors: Zhang Xianglun , Zhao Hongbo , Sheng Qingkai , Liu Xiaomu , You Wei , Lin Haichao , Liu Guifen
Published: March 2021

Abstract. MicroRNAs are short non-coding RNAs that regulate gene expression.
Several microRNAs, useful for coronary artery disease assessment, have
previously been identified. MicroRNA-33 is located within SREBP introns and
controls cholesterol homeostasis. In order to find the possibility of
microRNA-33 as a potential biomarker in high cholesterol disease, we
developed a mouse model for coronary heart disease by feeding mice with a
high-fat diet. The expression differences of microRNA-33, SREBP and ABCA1
genes in the liver, muscle, and lipid tissues were compared between a
high-cholesterol group and control group in mice. The results showed that
ABCA1 was up-regulated by high cholesterol conditions in liver, muscle and
lipid tissues. SREBP1C was up-regulated by high cholesterol conditions in
the liver and lipid tissues and down-regulated by high cholesterol
conditions in the muscle tissue. MicroRNA-33 and SREBP2 were down-regulated
by high cholesterol conditions in the liver and muscle tissues and
up-regulated by high cholesterol conditions in the lipid tissue. Our study
suggests that antisense therapeutic targeting of microRNA-33 may be a
potential biomarker for cardiovascular disease.
Characterizing and correcting the warm bias observed in AMDAR
temperature observations
Authors: de Haan Siebren , de Jong Paul M. A. , van der Meulen Jitze
Published: March 2021

Abstract. Some aircraft temperature observations, retrieved through the Aircraft Meteorological Data Relay (AMDAR), suffer from a significant warm bias when comparing observations with numerical weather prediction (NWP) model. In this manuscript we show that this warm bias of AMDAR temperature can be characterized and consequently reduced substantially. The characterization of this warm bias is based on the methodology of measuring temperature with a moving sensor and can be split into two separate processes. The first process depends on the flight phase of the aircraft and relates to difference of timing, as it appears that the time of measurement of altitude and temperature differ. When an aircraft is ascending or descending this will result in small bias in temperature due to the (on average) presence of an atmospheric temperature lapse rate. The second process is related to internal corrections applied to pressure altitude without feedback to temperature observation measurement. Based on NWP model temperature data combined with additional information on Mach number and true airspeed, we were able to estimate corrections using an 18 months period from January 2017 to July 2018. Next, the corrections were applied on AMDAR observations over the period from September 2018 to mid-December 2019. Comparing these corrected temperatures with (independent) radiosonde temperature observations demonstrates a reduction of the temperature bias from 0.5 K to around zero and reduction of standard deviation of almost 10 %.

Abstract. Semantic segmentation of ground-based all-sky images (ASIs) can provide high-resolution cloud coverage information of distinct cloud types, applicable for meteorology, climatology and solar energy-related applications. Since the shape and appearance of clouds is variable and there is high similarity between cloud types, a clear classification is difficult. Therefore, most state-of-the-art methods focus on the distinction between cloudy- and cloudfree-pixels, without taking into account the cloud type. On the other hand, cloud classification is typically determined separately on image-level, neglecting the cloud's position and only considering the prevailing cloud type. Deep neural networks have proven to be very effective and robust for segmentation tasks, however they require large training datasets to learn complex visual features. In this work, we present a self-supervised learning approach to exploit much more data than in purely supervised training and thus increase the model's performance. In the first step, we use about 300,000 ASIs in two different pretext tasks for pretraining. One of them pursues an image reconstruction approach. The other one is based on the DeepCluster model, an iterative procedure of clustering and classifying the neural network output. In the second step, our model is fine-tuned on a small labeled dataset of 770 ASIs, of which 616 are used for training and 154 for validation. For each of them, a ground truth mask was created that classifies each pixel into clear sky, low-layer, mid-layer or high-layer cloud. To analyze the effectiveness of self-supervised pretraining, we compare our approach to randomly initialized and pretrained ImageNet weights, using the same training and validation sets. Achieving 85.8 % pixel-accuracy on average, our best self-supervised model outperforms the conventional approaches of random (78.3 %) and pretrained ImageNet initialization (82.1 %). The benefits become even more evident when regarding precision, recall and intersection over union (IoU) on the respective cloud classes, where the improvement is between 5 and 20 % points. Furthermore, we compare the performance of our best model on binary segmentation with a clear-sky library (CSL) from the literature. Our model outperforms the CSL by over 7 % points, reaching a pixel-accuracy of 95 %.
Improving the monitoring of deciduous broadleaf phenology using the Geostationary Operational Environmental Satellite (GOES) 16 and 17
Authors: Wheeler Kathryn I. , Dietze Michael C.
Published: March 2021

Abstract. Monitoring leaf phenology tracks the progression of
climate change and seasonal variations in a variety of organismal and
ecosystem processes. Networks of finite-scale remote sensing, such as the
PhenoCam network, provide valuable information on phenological state at high
temporal resolution, but they have limited coverage. Satellite-based data with
lower temporal resolution have primarily been used to more broadly measure
phenology (e.g., 16 d MODIS normalized
difference vegetation index (NDVI) product). Recent versions of the Geostationary
Operational Environmental Satellites (GOES-16 and GOES-17) can monitor NDVI at
temporal scales comparable to that of PhenoCam throughout most of the
western hemisphere. Here we begin to examine the current capacity of these
new data to measure the phenology of deciduous broadleaf forests for the
first 2 full calendar years of data (2018 and 2019) by fitting
double-logistic Bayesian models and comparing the transition dates of the start, middle, and end of the
season to those obtained from PhenoCam and MODIS 16 d
NDVI and enhanced vegetation index (EVI) products. Compared to these MODIS products, GOES was more
correlated with PhenoCam at the start and middle of spring but had a larger
bias (3.35 ± 0.03 d later than PhenoCam) at the end of spring.
Satellite-based autumn transition dates were mostly uncorrelated with those
of PhenoCam. PhenoCam data produced significantly more certain (all
p values ≤0.013) estimates of all transition dates than any of the
satellite sources did. GOES transition date uncertainties were significantly
smaller than those of MODIS EVI for all transition dates (all p values ≤0.026), but they were only smaller (based on p value <0.05) than those
from MODIS NDVI for the estimates of the beginning and middle of spring. GOES will
improve the monitoring of phenology at large spatial coverages and provides
real-time indicators of phenological change even when the entire spring
transition period occurs within the 16 d resolution of these MODIS
products.
Quantifying the role of moss in terrestrial ecosystem carbon dynamics in
northern high-latitudes
Authors: Zha Junrong , Zhuang Qianlai
Published: March 2021

Abstract. In addition to woody and herbaceous plants, mosses are ubiquitous in northern terrestrial ecosystems, which play an important role in regional carbon, water and energy cycling. Current global land surface models without considering moss may bias the quantification of the regional carbon dynamics. Here we incorporate moss into a process-based biogeochemistry model, the Terrestrial Ecosystem Model (TEM 5.0), as a new plant functional type to develop a new model (TEM_Moss). The new model explicitly quantifies the interactions between higher plants and mosses and their competition for energy, water, and nutrient. Compared to the estimates using TEM 5.0, the new model estimates that the regional terrestrial soils store 132.7 Pg more C at present day, and will store 157.5 Pg and 179.1 Pg more C under the RCP 8.5 and RCP 2.6 scenarios, respectively, by the end of the 21st century. Ensemble regional simulations forced with different parameters for the 21st century with TEM_Moss predict that the region will accumulate 161.1 ± 142.1 Pg C under the RCP 2.6 scenario, and 186.7 ± 166.1 Pg C under the RCP 8.5 scenario over the century. Our study highlights the necessity of coupling moss into Earth System Models to adequately quantify terrestrial carbon-climate feedbacks in the Arctic.

Abstract. The Organization of Tropical East Pacific Convection (OTREC) field campaign investigated the dynamical structure of convection in the tropical east Pacific and Caribbean. One of the central data sets for this field campaign is the thermodynamic structure of the atmosphere measured by dropsondes released from the NSF/NCAR G-V research aircraft. Between 7 August and 2 October 2019, 648 dropsondes were successfully released from 22 research flights. Soundings were launched in a grid pattern with a typical spacing of 1∘ longitude and 1.2∘ latitude and provided profiles of pressure, temperature, humidity, and winds between the surface and on average 13.3 km. Of these soundings, 636 provided complete vertical profiles of all parameters with a nominal vertical resolution between 6 to 12 m from the surface to almost flight altitude. OTREC deployed the new NRD41 dropsonde, which is the most advanced model that has been developed at NCAR. Here, we describe the data set, the processing of the measurements, and general statistics of all dropsonde observations. The data set is available at https://doi.org/10.26023/EHRT-TN96-9W04 (UCAR/NCAR and Vömel, 2019).
Do small and large floods have the same drivers of change? A regional attribution analysis in Europe

Published: March 2021

Abstract. Recent studies have shown evidence of increasing and decreasing trends for average floods and flood quantiles across Europe. Studies attributing observed changes in flood peaks to their drivers have mostly focused on the average flood behaviour, without distinguishing small and large floods. This paper proposes a new framework for attributing flood changes to potential drivers, as a function of return period (T), in a regional context. We assume flood peaks to follow a non-stationary regional Gumbel distribution, where the median flood and the 100-year growth factor are used as parameters. They are allowed to vary in time and between catchments as a function of the drivers quantified by covariates. The elasticities of floods with respect to the drivers and the contributions of the drivers to flood changes are estimated by Bayesian inference. The prior distributions of the elasticities of flood quantiles to the drivers are estimated by hydrological reasoning and from the literature.
The attribution model is applied to European flood and covariate data and aims at attributing the observed flood trend patterns to specific drivers for different return periods at the regional scale. We analyse flood discharge records from 2370 hydrometric stations in Europe over the period 1960–2010. Extreme precipitation, antecedent soil moisture and snowmelt are the potential drivers of flood change considered in this study. Results show that, in northwestern Europe, extreme precipitation mainly contributes to changes in both the median (q2) and 100-year flood (q100), while the contributions of antecedent soil moisture are of secondary importance. In southern Europe, both antecedent soil moisture and extreme precipitation contribute to flood changes, and their relative importance depends on the return period. Antecedent soil moisture is the main contributor to changes in q2, while the contributions of the two drivers to changes in larger floods (T>10 years) are comparable. In eastern Europe, snowmelt drives changes in both q2 and q100.

Abstract. A novel measurement device for simultaneous high temperature measurements of the electrical conductivity and the Hall coefficient has been developed. Simulations were used to design a suitable screen-printed planar platinum heating structure that generates temperatures of up to 600 ∘C by Joule heating. Simulations of the temperature distribution have been validated using thermal imaging. With the hardware setup of two permanent magnetic yoke systems with a magnetic flux density of ±760 mT, the electrical conductivity and the charge carrier densities of a silicon wafer and a gold film were measured, as examples of a typical semiconductor with low charge carrier densities but high mobility and a metal representing materials with very high charge carrier densities but moderate mobilities, respectively. Measurements were compared with data from the literature to validate the functionality of the novel, low-cost measurement device.
