Authors: CAN Orhan Taner
Published: June 2020

Bu çalışmada toksik aromatik bir bileşik olarak bilinen fenolün BDD (Boron Doped Diamond), Ti/Pt ve MMO (Mixed Metal Oksit) elektrotları (Ti/RuO2-TiO2, Ti/RuO2-IrO2, Ti/IrO2-Ta2O5, Ti/Pt-IrO2) ile mineralizasyonu araştırıldı. Mineralizasyon seviyesinin belirlenmesi amacıyla deneylerin başında ve ilerleyen sürelerinde elektrooksidasyona tabi tutulan fenol çözeltisinden örnekler alınıp TOK (Toplam Organik Karbon) değerleri ölçüldü. Akım yoğunluğunun giderme verimine etkisini araştırmak için ise reaktöre üç farklı akım yoğunluğu (25 mA/cm2, 75 mA/cm2 ve 125 mA/cm2) uygulandı. Akım yoğunluğu artışı ile mineralizasyon veriminin artığı görülürdğ. 125 mA/cm2 akım yoğunluğunda BDD anot 180. dakikadan itibaren %100 giderme verimlerine ulaştı.  Deneyin başında düşük performans gösteren Pt elektrotun 300 dakikalık deney süresi sonunda % 84 lük giderme verimi ile, % 72-79 aralığında verim gösteren MMO anotların performansını geçtiği belirlendi. Çalışmanın sonunda BDD elektrodun fenolün sulardan gideriminde diğer anotlardan daha iyi performans gösterdiği görüldü.

The politics of renewable power in Spain
Authors: Duffield John S
Published: June 2020

Government support for renewable power in Spain has varied over time. After fostering a boom in the first decade of the 2000s, public support dried up in the early 2010s before making a reappearance in the last several years. This paper details and explains the fluctuating political fortunes of renewable power in Spain. It argues that the recent revival of support for renewable power should no come as no surprise. Rather, it reflects a reassertion of the underlying imperatives that prompted support by governments of different parties in previous years. Nevertheless, the role of government in promoting renewable power is now undergoing a fundamental change, as it shifts from directly subsidizing new generating capacity to removing barriers that might discourage private investment and facilitating the operation of market forces.
The effect of reduced unemployment duration on the unemployment rate: a Synthetic Control Approach
Authors: Stricker Luzius , Baruffini Moreno
Published: June 2020

This paper examines the impact of the fourth partial revision of the law of unemployment insurance (AVIG) on unemployment dynamics in Switzerland at a cantonal level. The authors apply the Synthetic Control Method (SCM), a matching method for comparative case studies. A counterfactual analysis of the cases studied is performed by combining a control group of several untreated units, which provides a better comparison to the treatment group than a single unit. The control unit is designed as a weighted average of the available cantons in the donor pool, taking into account the similarities between the chosen controls and the treated unit. Once policy changes are controlled, the results suggest a significant effect on the unemployment rate at a cantonal level: the reform had a discernible impact on lowering the unemployment rate in the Italian- and French-speaking cantons in Switzerland.
A comparative analysis of the European Union member states in terms of public spending on environmental protection in 2004-2017
Authors: Pawełek Barbara
Published: June 2020

The main purpose of the paper is to present the results of the comparative analysis of the member states of the European Union in terms of expenditure on environmental protection made by the public sector. An additional purpose of the paper is to verify whether there is convergence in public spending on environmental protection of the member states of the European Union. In the study, the convergence models and cluster analysis were used. The research results indicate, among others, that there was convergence in total public spending on environmental protection in the member states of the European Union in 2004-2017, and that the structure of the member states in terms of amounts of public spending on various aspects of environmental protection in 2004-2010 differed from the structure of the member states determined for the years 2011-2017.
Do confidence indicators have an impact on macro-financial indicators? An analysis of the financial service and real sector confidence indexes: evidence from Turkey
Authors: Kilci Esra N
Published: June 2020

The primary aim of this study is to analyze the impact of financial services and real sector confidence indexes on some macroeconomic and financial indicators such as industrial production, inflation, stock market index, foreign exchange rates and interest rates in Turkey for the period from May 2012 to May 2019. In this study, the unit root properties of these series are tested by using the Narayan and Popp (2010) unit root test with two structural breaks and the Enders and Lee (2012) Fourier ADF unit root test with multiple structural breaks. We investigate the causal link between confidence indicators and macro-financial variables using the Fourier Toda Yamamoto causality test proposed by Nazlioglu et al. (2016). The results suggest a strong link between financial services and real sector confidence indexes on macro-financial indicators such as stock market index and inflation, supporting the evidence of the short-run impact of confidence indexes on these variables.
A NOVEL FRAMEWORK FOR CARDIAC ARRHYTHMIA CLASSIFICATION BASED ON SUBSPACE PROJECTION AND DECISION TREE

Published: June 2020

Cardiac arrhythmia basically refers to
abnormal activity of heart. Correct classification of cardiac arrhythmia is
therefore crucial for appropriate treatment of heart diseases. In this paper, a
novel approach is proposed for cardiac arrhythmia classification. Initially,
the feature vectors extracted from raw electrocardiogram (ECG) signals are
projected into a particular subspace obtained via the Common Vector Approach,
which is an effective subspace method. The projected vectors are then fed into
two distinct decision-tree-based classifiers—namely, C4.5 and random forest.
The results obtained from the proposed approach are compared with those
obtained with the original feature vectors using the same classifiers. For this
purpose, the well-known MIT-BIH arrhythmia database was utilized. Six different
sets of features based on QRS, time-domain, wavelet transform and power
spectral density are derived from ECG signals in this database. The feature
sets are then used in the classification of five main beat types including
non-ectopic, ventricular ectopic, supraventricular ectopic, fusion and unknown.
The experimental results reveal that the recognition performances achieved by
most of the projected features are explicitly higher than those obtained with
the original ones. In addition, the classification accuracy of the proposed
approach climbs to 100% for the test set.
AN EXPERIMENTAL STUDY ON THE EFFICIENCY OF CHROMIUM (VI) REMOVAL WITH STARCH-MAGNETITE NANOCOMPOSITE (Starch@MNPs)
Authors: ŞİMŞEK Rojin , ÇİFTCİ Buşra Nur , UYSAL Yağmur
Published: June 2020

Nowadays, magnetic nanoadsorbents are
used commonly in the removal of heavy metal ions from wastewater. In this
study, we prepared starch-coated magnetic nanoparticles (Starch@MNPs) by the
co-precipitation method, and used to remove Cr(VI) ions from water. Several
batch experiments were performed to determine optimum conditions in the
adsorption studies for Starch@MNPs such as pH, contact time, temperature,
chromium ion and adsorbent concentrations. The synthesized Starch@MNPs were
analyzed by Scanning Electron Microscopy (SEM) to illustrate the shape and
surface properties of the nanoparticles. In order to define characterization of
the adsorbent, Fourier-transform infrared spectroscopy (FTIR) and Energy
Dispersive X-Ray Analysis (EDX) techniques were also used. The experimental
data were compared with isotherm and kinetic models in order to determine the
most suitable for fitting. The results showed that Cr (VI) adsorption of
Starch@MNPs was more suitable for Temkin isotherm and Psedudo-second kinetic
model, respectively. The maximum adsorption efficiency (98%) of Cr (VI) in 10
mg/L initial concentration was obtained at contact time of 60 min., pH 4.0 and
adsorbent concentration of 2.0 g/L. The obtained data from the study showed
that Starch@MNPs have quite high separation efficiency for Cr(VI) ions and also
showed that this adsorbent can be used as a promising adsorbent in future
adsorption studies.
HOURLY GLOBAL SOLAR RADIATION ESTIMATION BASED ON MACHINE LEARNING METHODS IN ESKISEHIR
Authors: ALSAFADI Massa , BAŞARAN FİLİK Ümmühan
Published: June 2020

Due to the increasing importance of knowing the global
solar radiation (GSR) amount incident on solar panels; short term data, such as
hourly global solar radiation (HGSR), is essentially required to obtain more accurate
and reliable power generation prediction. Nowadays, Machine Learning (ML)
methods are becoming a huge trend for data forecasting. Therefore, in this
paper, a comparison between Collares-Pereira & Rabl empirical model modified
by Gueymard (CPRG) and ML methods for HGSR estimation in Eskişehir city
in Turkey is conducted. Artificial Neural Network (ANN), Regression Tree (RT)
and Support Vector Regression (SVR) are ML methods that are used to predict
HGSR. Besides, hourly metrological and geographical parameters for the year
2014 are taken as inputs in the training models. The inputs are solar time,
solar hour angle, Julian day number, daily GSR, altitude, longitude, latitude, hourly
average humidity, hourly temperature and hourly pressure. To demonstrate these
techniques, a comparison is implemented using MATLAB software with the help of
existing toolboxes. Finally, this study proved that ML methods outperform the
CPRG model and not to mention that they have far more accurate results.
Although almost all ML models gave similar results, SVR
was the best among them with a correlation coefficient of 0.979532 for the
training set and 0.978244 for the testing set. In a nutshell, ML are successful
methods that should be to be taken into consideration to perfectly estimate
HGSR now and in the future in the field of solar renewable energy estimation.

Authors: ERDEM Beyhan , BİLGİN Kübra
Published: June 2020

A multifunctional heterogeneous acid catalyst named as spFe3O4@SBA-15@HPW was prepared, which consists of versatile properties such as magnetic separability, high conversion efficiency and reusability. This catalyst was characterized by XRD, FT-IR, VSM, TEM and SEM/EDX techniques with respect to structural, morphological and magnetic properties. The catalyst showed higher catalytic activity than the commercial catalysts such as Amberlyst-15 and Dowex 50Wx4 and also heteropoly tungstic acid (HPW) alone in terms of conversion of oleic acid for biodiesel production by the esterification of oleic acid with methanol. The experimental data were correlated by pseudo-first-order homogeneous and Eley-Rideal heterogeneous models, and the results demonstrate the suitability of Eley-Rideal mechanism.

Published: June 2020

A acuidade de se obter o conhecimento da diversidade de abelhas nativas de um determinado local e suas inter-relações com o ecossistema são inúmeras, afinal, além de serem os maiores polinizadores e responsáveis pelo desenvolvimento das plantas existentes do meio ambiente, também se destacam pelo seu valor econômico e sociocultural. Objetivou-se registrar o etnoconhecimento sobre abelhas sem ferrão pelos moradores da comunidade José Gomes, município de Cabeceiras do Piauí, Piauí. Os dados foram levantados por meio de entrevistas semiestruturadas aplicadas a 43 atores locais, sendo 39 homens e quatro mulheres. Os meliponíneos foram capturados por meio de rede entomológica e vasilhames, e encaminhados para identificação. Foram coletados 124 espécimes, distribuídos em seis gêneros e 13 espécies de abelhas sem ferrão. Das espécies amostradas, as mais abundantes foram Scaptotrigona sp. (n=25), Trigona sp. (n=17), Tetragona sp. (n=14), Trigona spinipes (n=13) e Partamona ailyae (n=10). O índice de Shannon-Wiener (H’) foi utilizado para estimar a diversidade de abelhas sem ferrão, que foi de H’=1,02. Constatou-se que os moradores percebem e reconhecem a diversidade de meliponíneos existentes na área estudada, não obstante é necessário que se estabeleça maior divulgação sobre a importância do papel desses insetos para a conservação do ecossistema, aprimorado por meio de uma intensificada educação ambiental, principalmente no que concerne a conservação das abelhas sem ferrão e das plantas melitófilas.

Published: June 2020

Purpose: The aim of this study to highlight the role of entrepreneurial culture in the relationship between entrepreneurship education and entrepreneurial intentions at higher education institutions as study variables. This study could play a vital role in guiding students to choose entrepreneurship as a career by encouraging them.

Methodology: A scoping review method was used to identify critical evidence in the reviewed relationships between the three above mentioned variables, which are: entrepreneurship education, entrepreneurial culture, and entrepreneurial intention. By using the scoping review method, the authors analyzed articles from Scopus and Web of Science databases published from the year 2003 to 2019, in which 52 relevant articles out of 105 related published articles were identified using Mendeley software to filter these articles. 

Main Findings: The results show that there was a significant positive relationship between entrepreneurship education, entrepreneurial culture, and entrepreneurial intention when the entrepreneurial culture was inculcated in entrepreneurship education activities at higher education institutions. This study shows that the most used theory is the Theory of Planned Behavior, in which most studies were done on the level of universities, and a significant volume of reviews have been carried out in developed countries.

Application of This study: The cultivation of entrepreneurial competencies is heavily influenced by the prevailing culture, which is usually strengthened through education and directed by individual entrepreneurial intention along with the role of entrepreneurial culture. Hence, this could be useful for developing and economies in transition countries that might face high unemployment rates to focus on these variables in comparison to developed countries.

Novelty: This study highlights and further proposes the mediation role of entrepreneurial culture in entrepreneurship education - entrepreneurial intention relationship based on the outcomes of the scoping review. Indeed, this relationship was just mentioned by words and not validated or measured comprehensively by the scholars. Hence, there is a chance for further studies in this body of knowledge.

Published: June 2020

Current energy policy and climate mitigation goals require distinct reductions of the primary energy demand in the building sector. The existing building stock poses challenge since clear-cut technical and economical retrofit strategies for different types of existing buildings are still not established. The goal of the study is to identify such retrofit strategies to achieve optimal cost levels and to assess costs and benefits of nearly zero energy buildings (nZEB). Firstly building types are defined by covering single-family houses, multi-family houses, office buildings and school buildings. Secondly, a large set of generic energy efficiency measures are described, covering seven strategic fields, namely building envelope measures, heating and hot water supply technologies and fuel choice, ventilation and lighting systems, electricity and district heat mixes. This covers the usage of smart home appliances, eco-friendly building ventilation system. Thirdly, energy performance is calculated based on technical and physical characteristics and using building energy balance software. Fourthly, investment costs and life cycle costs are established based on unitary costs of building elements and building technologies. Cost-effectiveness is determined based on he net present value method which is compared to the annuity method for a couple of cases. The integration of smart grid and IoT(Internet of Things) is a new concept for conserving more.

The paper presents that encryption of compressed video bit streams and hiding privacy information to protect videos during transmission or cloud storage. Digital video sometimes needs to be stored and processed in an encrypted format to maintain security and privacy. Here, data hiding directly in the encrypted version of H.264/AVC video stream is approached, which includes the following three parts. By analyzing he property of H.264/AVC codec, the code words of intra prediction modes, the code words of motion vector differences, and the code words of residual coefficients are encrypted with stream ciphers. Then, a data hider may embed additional data in the encrypted domain by using wrapping technique, without knowing the original video content. The paper results shows that used methods provides better performance in terms of computation efficiency, high data security and video quality after decryption. The parameters such as RMSE, PSNR, CC are evaluated to measure its efficiency

Published: June 2020

The main goal of reversible data hiding algorithms is to embed the secret information in cover image and recover it back successfully. So we have implemented two methods. In first method, cover image is encrypted using stream cipher and pseudo randomly generated key and compressed using haar wavelet compression. The encrypted compressed image acts as a media for hiding secret image. And in second method, secret image is encrypted using randomly generated key and it is hidden in cover image. In both the method data hiding is done using LSB based image steganography. At the receiver, reverse process is done to extract secret image and recover cover image. At the end, we conclude that second method gives better security of image compared to method one.

Authors: Sequeira Royden , Sebastian Renil , Bunde Yogesh , Suryawanshi Uday
Published: June 2020

In the terms of damage caused to the environment, air pollution can be easily characterized as the main culprit .The main sources of air pollution are industries. Therefore, this paper aims at using semi-conductor sensor for detecting the various pollutant gases at the emission outlets which detects the level of pollutants in the industries. Specifically in this paper, gas sensor MQ135 is used. When the pollution/emission level shoots beyond the permissible level, the process/machinery causing the polluted emission is immediately shut down and there will be an alarm (light alarm or buzzer) to indicate that the limit has been reached at a specific emission outlet. Simultaneously, the factory control room will be informed via GSM that the process/ machinery has been shut down and corrective action has to be taken. The execution and synchronization of the entire process is monitored and controlled by a microcontroller (PIC16F877A).
DATA COMMUNICATION USING VISIBLE LIGHT
Authors: Kinny Tyran , Puthuva Franklin , Komban Ashore , Belekar Dipti
Published: June 2020

Visible Light Communication (VLC) using a Light Fidelity system, as proposed by a German physicist—Harald Haas, provides transmission of data through illumination by sending data through an LED light source that varies in intensity that can be controlled and adjusted such that it appears as normal light to the naked human eye. Here the property of persistence of vision of the human eye is exploited for additional application of a free, sustainable and green source that can be used for wireless communication at very fast data rates. This paper focuses on developing a low cost Li-Fi based system and analyses its performance with respect to existing wireless technology. Wi-Fi is great for general wireless coverage within buildings, whereas Li-Fi is ideal for high density wireless data coverage in confined area and for relieving radio interference issues. Li-Fi based system provides better bandwidth, efficiency, availability and security than Wi-Fi and has already achieved higher data rates. By leveraging the low-cost nature of LEDs and lighting units there are many opportunities to exploit this medium, from public internet access through day-to-day light sources which have their primary purpose of only emitting light. This project envisions a future where data for communication devices will be transmitted through the visible spectrum thus de-clogging the currently overused RF spectrum.
AN INVESTIGATION OF SYMBIOTIC RELATIONS BETWEEN TOURISM AND DEVELOPMENT
Authors: Devi Kanchan , Upadhyay Vandana
Published: June 2020

Purpose of this study: Growth in the tourism sector helps in the reduction of poverty, maintenance of macroeconomic equilibrium by creating employment opportunities, earning foreign currencies, reduction of excessive dependence on a foreign country for their own development, reduction of the deficit of the current account of the balance of payment, etc. This study aims to acquaint deeply with the relationship between tourism and development so that we can check complexities, gaps, comparability, and the sustainability of impact on each other.

Methodology: Secondary sources of data are used in this descriptive research.

Main findings of my study: There is a symbiotic relationship between tourism and development and one cannot be separated from others and both are the causes of each other. From the empirical study of different countries with the co-integration method, it is proved that tourism has always been positively related to development.

Applications of my study: The study will be helpful to students, research scholars, different government & nongovernmental officials who are interested in any activities relating to tourism, environment and economy, academicians, environmentalists, tourists, and anyone interested in knowing the symbiotic relationship between tourism and development.

Novelty/Originality of this study: The novelty of the study lies in the hardness of finding such litterateurs, which are directly related to finding the symbiotic relations between tourism and development. The relations between the two are not one way or simple, there are many other factors like environment, externality, the spillover effect of government activities, etc. that affects the relationship. In this study, I tried to take all of this together to study the symbiotic relationship between tourism and development.
Cooperativas agropecuarias. Un factor indispensable para la soberanía alimentaria en Cuba
Authors: Acosta Morales Yaumara
Published: June 2020

Las cooperativas agropecuarias son la herramienta comúnmente utilizada a nivel mundial para promover procesos de integración. La globalización de los mercados y el aumento maximizado de la competencia hacen precisa una vertiginosa y eficiente respuesta en el cooperativismo internacional. Las decisiones arrogadas por las sociedades cooperativas han ido orientadas a la ejecución de procesos de integración o concentración, siendo la constitución de cooperativas de segundo grado una de las vías más estiladas. Las Cooperativas agropecuarias son empresas vinculadas de forma estable al territorio rural y al productor agroalimentario. Además, ejercen el liderazgo en la economía de estas áreas y en la fijación de población en municipios rurales, contribuyendo así al equilibrio, la ordenación y el desarrollo rural.Recibido: 03 marzo 2020Aceptado: 20 abril 2020Publicación en línea: 14 junio 2020
El asunto cooperativo en Cuba. Perspectivas
Authors: Fernández Peiso Avelino
Published: June 2020

La cooperativa en Cuba ha sufrido diversos abordajes. Hoy se mueve en un ambiente legal agropecuario y otro no agropecuario, sentados en normas legales no expresivas de su naturaleza social y aún pendiente de una Norma General de Cooperativas; asunto de suprema trascendencia para el proyecto socialista cubano del siglo XXI, en sede de que, si bien las cooperativas nacen en el capitalismo como respuesta de los desposeídos a las aberrantes formas de explotación, en el socialismo emergen por su naturaleza humanista y su capacidad de contribuir al desarrollo ético, moral, ideológico, socioeconómico y a los valores peculiares de la sociedad cubana. Para el desarrollo de esta contribución, el Estado cubano está obligado a garantizar eficiente promoción y fomento estatal. Sobre esta base, es propósito del presente trabajo incursionar en la cooperativa como institución socio/jurídica; la problemática del asunto cooperativo cubano, y en los planteos teóricos como fundamentos de su solución.Recibido: 10 febrero 2020Aceptado: 06 abril 2020Publicación en línea: 14 junio 2020
La asesoría jurídica en pos de la identidad cooperativa. Potenciales contribuciones a las Cooperativas No Agropecuarias cubanas
Authors: Rodríguez Musa Orestes
Published: June 2020

En Cuba, con el proceso de actualización del modelo socioeconómico, se han implementado nuevas formas de trabajo cooperado en sectores diferentes al agropecuario. Estas formas asociativas presentan dificultades que las apartan de la identidad cooperativa universalmente reconocida; sin embargo, la asesoría jurídica puede contribuir en este sentido. En el presente trabajo se explican estas potencialidades de la asesoría jurídica y, a continuación, se argumenta este propósito para las Cooperativas No Agropecuarias cubanas, de cara a los principios cooperativos enarbolados por la Alianza Cooperativa Internacional y a las recientes transformaciones legislativas implementadas en el país para el sector.Recibido: 30 marzo 2020Aceptado: 24 abril 2020Publicación en línea: 14 junio 2020
La actividad registral relativa a las cooperativas en Cuba. Perspectivas para su desarrollo
Authors: Hernández Aguilar C. Orisel
Published: June 2020

El presente trabajo se propone fundamentar algunos presupuestos que sirvan de guía para contribuir al perfeccionamiento de la actividad registral relativa a las cooperativas en Cuba. Este empeño coincide con los esfuerzos del país en tal dirección, puesto que han sido promulgadas normas nuevas para los distintos ámbitos del cooperativismo nacional en las que se han establecido las bases para una progresiva unificación del sistema registral de estos entes. A tal fin se analizarán los referentes históricos que vinculan a las instituciones estudiadas, se contrapondrán los regímenes jurídicos que ordenaron, por años, el tratamiento diferenciado de la actividad registral para el sector agropecuario y el que no lo es, y, finalmente, se formulará la aludida propuesta de presupuestos.Recibido: 20 marzo 2020Aceptado: 22 abril 2020Publicación en línea: 14 junio 2020

Authors: DURMUŞ Ensar , GÜNEYSU Fatih
Published: June 2020

COVID-19 disease is a worldwide pandemic. Patients present to hospitals with upper and lower respiratory tract symptoms such as cough, fever, shortness of breath, however it can also be encountered with many different clinics. We aimed to share the patient who has COVID-19 and presented with stroke. A 67-year-old female patient presented to the emergency service complaints of mental fog and shortness of breath. She had known lung cancer, hypertension and diabetes. There were no signs compatible with COVID-19 in her history or examination. No feature was detected in her blood tests. Diffuse cerebral infarction was observed in diffusion MRI examination. The patient, whose general condition was poor, was taken into follow up in intensive care unit. On the eighth day of her follow-up, the patient passed away. In places where COVID-19 disease is observed commonly, it would be appropriate for emergency physicians to take COVID-19 disease into consideration in stroke cases.

Unamuno, Don Juan and the Mal du siècle
Authors: Rivera Leonarda
Published: June 2020

Don Juan by Miguel de Unamuno belongs to the gallery of old and tired “donjuanes” that begin to populate the European Literature from late Nineteenth Century and extends into the Twentieth Century, that not only shows the inside of a series of elements of their own age like Boredom, Fatigue, Weariness, Tedium, etc., but also illustrates how this figure, that was born with Modernity, in the end also succumbs to the end-of-century crisis.

Authors: Dias Danilo Camargo , Moreira Walter , Alves Rachel Cristina Vesu
Published: June 2020

O crescimento das redes sociais e a forma de representar os seus recursos tornou-se objeto de diversos estudos na Ciência da Informação (CI). A imagem digital carrega uma dificuldade em relação a sua representação temática nesses redes sociais. Assim, o problema deste estudo consiste em investigar a recuperação da informação nas redes sociais, principalmente em redes que disponibilizam imagens digitais. Objetiva-se analisar as contribuições do Sistema de Organização do Conhecimento – SOC – da National Aeronautics and Space Administration - NASA, na representação temática de imagens digitais disponibilizadas em redes sociais do Flickr. Utilizou-se como metodologia a abordagem exploratória e descritiva, o que oportunizou o levantamento bibliográfico dos aspectos teóricos e a análise da terminologia em imagens digitais na NASA do Flickr. Por isso, foram analisados os termos de representação temática não controlados descritos por folksonomias e os termos controlados advindos do tesauro da NASA. Como resultados da análise destaca-se os desafios gerados no uso da folksonomia na representação temática de imagens digitais e as vantagens do uso do SOC no processos de representação temática e recuperação da informação nesses ambientes. Conclui-se que as folksonomias representam livremente os termos e refletem a realidade terminológica de uma comunidade; enquanto que os SOC contribuem para um controle de vocabulário e recuperação da informação mais precisa.
From “Infodemics” to Health Promotion: A Novel Framework for the Role of Social Media in Public Health
Authors: Schillinger Dean , Chittamuru Deepti , Ramírez A. Susana
Published: June 2020

Despite the ubiquity of health-related communications via social media, no consensus has emerged on whether this medium, on balance, jeopardizes or promotes public health. During the COVID-19 pandemic, social media has been described as the source of a toxic “infodemic” or a valuable tool for public health. No conceptual model exists for examining the roles that social media can play with respect to population health.

We present a novel framework to guide the investigation and assessment of the effects of social media on public health: the SPHERE (Social media and Public Health Epidemic and REsponse) continuum. This model illustrates the functions of social media across the epidemic–response continuum, ranging across contagion, vector, surveillance, inoculant, disease control, and treatment.

We also describe attributes of the communications, diseases and pathogens, and hosts that influence whether certain functions dominate over others. Finally, we describe a comprehensive set of outcomes relevant to the evaluation of the effects of social media on the public’s health.
La identidad geográfica del Parque Nacional de los Picos de Europa: la dificultad de su gestión
Authors: Rodríguez Gutiérrez Fermín , Menéndez Fernández Rafael , Pulgar Díaz Cristina
Published: June 2020

Los Picos de Europa son representativos de la montaña cantábrica. Con una parte, en 1918, se configuró el primer Parque Nacional español, ampliado en 1995 a la totalidad del macizo; por lo que incluye entidades de población y núcleos de aprovechamiento ganadero. Tras un complejo proceso administrativo, en el que han variado los enfoques con los que se trata su gestión, hoy sigue sin resolverse la fórmula que compatibilice las actividades económicas con la política de conservación del medio, lo que provoca un bloqueo persistente, atribuido a los cambios en el sistema de regulación del Estado, que va pasando de unitario a compuesto, y a la utilización de un enfoque sectorial, naturalista y burocrático, para resolver un problema que es de ordenación del territorio, por lo que necesita el enfoque holístico para su planificación y la lógica de proyecto para su gestión, integradas por evaluadores territoriales, capaces de conciliar las regulaciones funcionales y administrativas, mediante el conocimiento y el principio de cooperación, con la finalidad de conseguir la ocupación dinámica del territorio del Parque Nacional y de las comarcas que lo acogen, como medio de preservar su misión territorial de reserva de importantes recursos para la población.

Published: June 2020

Background: Carbofuran is a widely used broad-spectrum pesticide that, despite strict regulation and being banned for more than a decade, is still encountered in cases of intentional poisoning in dogs and wildlife. The objective of the study was to provide a complete and detailed description of the pathological, histological and toxicological findings of 7 cases of intentional carbofuran poisoning in dogs.Results: In this retrospective study, 7 cases of carbofuran intoxication recorded from July 2015 to June 2017 were analyzed. Following complete history recording, all cases were examined by complete necropsy and histopathology. Carbofuran intoxication was confirmed in all cases by gas chromatography. The postmortem examination revealed extensive hemorrhaging and congestion located mainly within the respiratory, nervous and cardiovascular systems, accompanied by degeneration and necrosis within the lungs, heart, and kidneys.Conclusions: Although carbamates have been banned in the European Union, carbamate poisoning is still frequently encountered, especially in wild animals. This paper will contribute to a better understanding of the occurrence and pathogenesis of acute carbofuran exposure in dogs and contribute some peculiar pathological features of this type of poisoning to the current literature.

Background: Previous studies show that galanin neurons in ventrolateral preoptic nucleus (VLPO-Gal) are essential for sleep regulation. Here, we explored the transcriptional regulation of the VLPO-Gal neurons in sleep by comparing their transcriptional responses between sleeping mice and those kept awake, sacrificed at the same diurnal time. Results: RNA-sequencing (RNA-seq) analysis was performed on eGFP(+) galanin neurons isolated using laser captured microdissection (LCM) from VLPO. Expression of Gal was assessed in our LCM eGFP(+) neurons via real time qPCR and showed marked enrichment when compared to LCM eGFP(-) neurons and to bulk VLPO samples. Gene set enrichment analysis utilizing data from a recent single-cell RNA-seq study of the preoptic area demonstrated that our VLPO-Gal samples were highly enriched with galanin-expressing inhibitory neurons, but not galanin-expressing excitatory neurons. A total of 263 genes were differentially expressed between sleep and wake in VLPO-Gal neurons. When comparing differentially expressed genes in VLPO-Gal neurons to differentially expressed genes in a wake-active neuronal region (the medial prefrontal cortex), evidence indicates that both systemic and cell-specific mechanisms contribute to the transcriptional regulation in VLPO-Gal neurons. In both wake-active and sleep-active neurons, ER stress pathways are activated by wake and cold-inducible RNA-binding proteins are activated by sleep. In contrast, expression of DNA repair genes is increased in VLPO-Gal during wakefulness, but increased in wake-active cells during sleep. Conclusion: Our study identified transcriptomic responses of the galanin neurons in the ventrolateral preoptic nucleus during sleep and sleep deprivation. Data indicate that VLPO contains mainly sleep-active inhibitory galaninergic neurons. The VLPO galanin neurons show responses to sleep and wake similar to wake-active regions, indicating these responses, such as ER stress and cold-inducible RNA-binding proteins, are systemic affecting all neuronal populations. Region-specific differences in sleep/wake responses were also identified, in particular DNA repair. Our study expands knowledge about the transcriptional response of a distinct group of neurons essential for sleep.
