Authors: Li Ying , de La Rochefoucauld Ombeline , Zeitoun Philippe
Published: November 2020

In recent years, integral imaging, a promising three-dimensional imaging technology, has attracted more and more attention for its broad applications in robotics, computational vision, and medical diagnostics. In the visible spectrum, an integral imaging system can be easily implemented by inserting a micro-lens array between a image formation optic and a pixelated detector. By using a micro-Fresnel Zone Plate (FZP) array instead of the refractive lens array, the integral imaging system can be applied in X-ray. Due to micro-scale dimensions of FZP in the array and current manufacturing techniques, the number of zones of FZP is limited. This may have an important impact on the FZP imaging performance. The paper introduces a simulation method based on the scalar diffraction theory. With the aid of this method, the effect of the number of zones on the FZP imaging performance is numerically investigated, especially the case of very small number of zones. Results of several simulation of FZP imaging are presented and show the image can be formed by a FZP with a number of zones as low as 5. The paper aims at offering a numerical approach in order to facilitate the design of FZP for integral imaging.

Published: November 2020

Spectroscopic techniques based on Distributed FeedBack (DFB) Quantum Cascade Lasers (QCL) provide good results for gas detection in the mid-infrared region in terms of sensibility and selectivity. The main limitation is the QCL relatively low tuning range (~10 cm−1) that prevents from monitoring complex species with broad absorption spectra in the infrared region or performing multi-gas sensing. To obtain a wider tuning range, the first solution presented in this paper consists of the use of a DFB QCL array. Tuning ranges from 1335 to 1387 cm−1 and from 2190 to 2220 cm−1 have been demonstrated. A more common technique that will be presented in a second part is to implement a Fabry–Perot QCL chip in an external-cavity (EC) system so that the laser could be tuned on its whole gain curve. The use of an EC system also allows to perform Intra-Cavity Laser Absorption Spectroscopy, where the gas sample is placed within the laser resonator. Moreover, a technique only using the QCL compliance voltage technique can be used to retrieve the spectrum of the gas inside the cavity, thus no detector outside the cavity is needed. Finally, a specific scheme using an EC coherent QCL array can be developed. All these widely-tunable Quantum Cascade-based sources can be used to demonstrate the development of optical gas sensors.

Published: November 2020

The high heterogeneity of 5G use cases requires the extension of the traditional per-component testing procedures provided by certification organizations, in order to devise and incorporate methodologies that cover the testing requirements from vertical applications and services. In this paper, we introduce an experimentation methodology that is defined in the context of the 5GENESIS project, which aims at enabling both the testing of network components and validation of E2E KPIs. The most important contributions of this methodology are its modularity and flexibility, as well as the open-source software that was developed for its application, which enable lightweight adoption of the methodology in any 5G testbed. We also demonstrate how the methodology can be used, by executing and analyzing different experiments in a 5G Non-Standalone (NSA) deployment at the University of Malaga. The key findings of the paper are an initial 5G performance assessment and KPI analysis and the detection of under-performance issues at the application level. Those findings highlight the need for reliable testing and validation procedures towards a fair benchmarking of generic 5G services and applications.

Published: November 2020

Physiological pressure measurement is one of the most common applications of sensors in healthcare. Particularly, continuous pressure monitoring provides key information for early diagnosis, patient-specific treatment, and preventive healthcare. This paper presents a thin-film flexible wireless pressure sensor for continuous pressure measurement in a wide range of medical applications but mainly focused on interface pressure monitoring during compression therapy to treat venous insufficiency. The sensor is based on a pressure-dependent capacitor (C) and printed inductive coil (L) that form an inductor-capacitor (LC) resonant circuit. A matched reader coil provides an excellent coupling at the fundamental resonance frequency of the sensor. Considering varying requirements of venous ulceration, two versions of the sensor, with different sizes, were finalized after design parameter optimization and fabricated using a cost-effective and simple etching method. A test setup consisting of a glass pressure chamber and a vacuum pump was developed to test and characterize the response of the sensors. Both sensors were tested for a narrow range (0–100 mmHg) and a wide range (0–300 mmHg) to cover most of the physiological pressure measurement applications. Both sensors showed good linearity with high sensitivity in the lower pressure range <100 mmHg, providing a wireless monitoring platform for compression therapy in venous ulceration.

Published: November 2020

Laser time transfer is of great significance in timing and global time synchronization. However, the temperature drift may occur and affect the delay of the electronics system, optic generation and detection system. This paper proposes a post-processing method for the compensation of temperature-induced system delay, which does not require any changes to the hardware setup. The temperature drift and time stability of the whole system are compared with and without compensation. The results show that the propagation delay drift as high as 240 ps caused by temperature changes is compensated. The temperature drift coefficient was diminished down to ~0.05 ps/°C from ~20.0 ps/°C. The system precision was promoted to ~2 ps from ~11 ps over a time period of 80,000 s. This method performs significant compensation of single-photon laser time transfer system propagation drift and will help to establish an ultra-stable laser time transfer link in space applications.

Authors: Božič Alex , Kos Matjaž , Jezeršek Matija
Published: November 2020

The increase in complex workpieces with changing geometries demands advanced control algorithms in order to achieve stable welding regimes. Usually, many experiments are required to identify and confirm the correct welding parameters. We present a method for controlling laser power in a remote laser welding system with a convolutional neural network (CNN) via a PID controller, based on optical triangulation feedback. AISI 304 metal sheets with a cumulative thickness of 1.5 mm were used. A total accuracy of 94% was achieved for CNN models on the test datasets. The rise time of the controller to achieve full penetration was less than 1.0 s from the start of welding. The Gradient-weighted Class Activation Mapping (Grad-CAM) method was used to further understand the decision making of the model. It was determined that the CNN focuses mainly on the area of the interaction zone and can act accordingly if this interaction zone changes in size. Based on additional testing, we proposed improvements to increase overall controller performance and response time by implementing a feed-forward approach at the beginning of welding.
Advances in Wearable Sensors: Signalling the Provenance of Garments Using Radio Frequency Watermarks
Authors: Foroughi Javad , Safaei Farzad , Raad Raad , Mitew Teodor
Published: November 2020

There is a significant nascent market for ethically produced products with enormous commercial potential around the world. A reliable method to signal the provenance of products is therefore critical for industry, given that competition based on price is not a viable strategy. The ability to trace and signal ethical treatment of animals is also of significant value to textiles manufactures. The efficacy of such a method can be measured with respect to the cost of implementation, scalability, and the difficulty of counterfeiting. The key to traceability is to win the trust of the consumer about the veracity of this information. Wearable sensors make it possible to monitor and improve the management of traceability and/or provenance. In this paper, we introduce a method for signalling the provenance of garments using radio frequency watermarks. The proposed model consists of two levels of authentication that are easy to use by legitimate vendors, but extremely difficult to imitate or hack, because the watermark is built-in and based on the radiation signature of electroactive materials.

Authors: Seljeseth Mats , Yamin Muhammad Mudassar , Katt Basel
Published: November 2020

Information Technology (IT) has become an essential part of our lives and due to the emergence of the Internet-of-Things (IoT), technology has encompassed a majority of things that humans rely on in their daily lives. Furthermore, as IT becomes more relevant in daily lives, the need for IT to serve public emergency services has become more important. However, due to the infancy status of IoT, there is a need for a data consortium that would prove to be best used in servicing policing in a technological driven society. This paper will discuss the plausibility of creating a universal format for use in carrying out public services, such as emergency response by the police and regular law maintenance. In this research we will discuss what the police requires in their line-of-duty and how smart devices can be used to satisfy those needs. A data formatting framework is developed and demonstrated, with the goal of showing what can be done to unifying data from smart city sensors.

Social innovation is recognised for its potential to turn societal challenges into opportunities and develop sustainable solutions for people and nature. We identify and examine challenges that Ukrainian forestry is facing and apply an “action arena” conceptual approach to explore whether and how social innovation can enhance the sustainable development of forestry. We develop a framework to analyse the reconfiguration of social practices by using research methods that focus on the use of documentation of the institutional contexts and interviewing forest policy experts, as well as stakeholder evaluation of the challenges and ways forward for Ukrainian forestry. We apply the Q-method to identify stakeholder attitudes and examine the role of people in the reconfiguring of social practices and promoting sustainable development of the forest sector. Implications for changing the rules of the game and institutional perspectives on forestry are identified, with examples of social innovation initiatives presented. Results show that to emerge, develop, and be transformative, social innovation must have supporting institutional conditions to create new norms, rules, and social practices. Relevant stakeholders need to envision alternative futures, reshape places, and become more actively engaged in decision-making processes. We identify the key directions for changing the rules of the game and the opportunities that social innovation has to offer.

Published: November 2020

Precast concrete elements provide a feasible way to expedite on-site construction; however, typical precast components are massive, making their use particularly undesirable at construction sites that suffer from low load-bearing capacity or have swelling soils. This research aims to develop an optimal lightweight expanded polystyrene foam concrete (EPS-foam concrete) slab through a consideration of various parameters. The precast EPS-foam concrete half-shaped slabs were prepared with a density and compressive strength of 1980 kg/m3 and 35 MPa, respectively. Quarry dust (QD) and EPS beads were utilized as substitutions for fine and coarse aggregates with replacement-levels that varied from 5% to 22.5% and 15% to 30%, respectively. The use of EPS beads revealed sufficient early age strength; at the same time, the utilization of quarry dust in EPS-foam concrete led to a more than 30% increase in compressive strength compared to the EPS-based mixtures. Two hundred and fifty-six trial mixes were produced to examine the physical and mechanical characteristics of EPS-foam concrete. Three batches of a total of four EPS-foam concrete half-shaped slabs with spans of 3.5 and 4.5 m and thicknesses of 200 and 250 mm were prepared. Findings showed that the ultimate shear forces for the full-scale EPS-foam concrete half-shaped slabs were approximately 6–12% lower than those of the identical concrete samples with a 2410 kg/m3 average density, and 26–32% higher than the theoretical predictions. Also, it was observed that the self-weight of EPS-foam concrete was reduced by up to 20% compared to the control mixtures. Findings revealed that the prepared precast EPS-foam concrete half-shaped slabs could possibly be applied as flooring elements in today’s modern infrastructure.
Growing Together: Community Coalescence and the Social Dimensions of Urban Sustainability
Authors: Glennie Charlotte
Published: November 2020

Urban sustainability is most often measured using a series of social, economic, and ecological indicators. Assessment methods for urban sustainability typically factor in the ecological dimensions of greenspace, such as biodiversity maintenance, stormwater management, and/or air quality—yet indicator schemas that consider only the ecological dimensions largely overlook the social benefits of some types of urban greenspace, particularly community gardens and orchards. This article makes the case that the process of community formation and strengthening that occurs in shared growing spaces is an important element of urban sustainability in its own right. Based on 55 interviews of community garden advocates, policy-makers, and development professionals involved in urban agriculture planning, this article traces the widespread understanding among practitioners that shared growing spaces strengthen social as well as environmental sustainability, though the social benefits are often difficult to measure. The latter concern was most frequently expressed by urban agriculture advocates who, after involvement in the political process, perceived the need for such metrics in order to communicate persuasively with planners and policy makers. The social values of shared growing spaces, at once self-evident to garden advocates and difficult for them to demonstrate with quantitative data, may be theorized by drawing on insights from sociology: A truly sustainable city requires community coalescence among diverse citizens, and such community is fostered particularly well in shared growing spaces.

Authors: Apud Agustina , Faggian Robert , Sposito Victor , Martino Diego
Published: November 2020

Urban green infrastructure (UGI) has the potential to address a wide range of challenges associated with rapidly growing cities in a changing climate, while also providing multiple environmental, economic and social benefits. However, the location of projects is often determined according to a single potential benefit rather than a set of benefits. Furthermore, while UGI is recognized as a successful strategy to support resilience in many cities around the world, it has not been implemented in Uruguay. This study develops a model to identify priority areas in need of green infrastructure in Montevideo, Uruguay. The GIS-based model, termed the “Green Infrastructure Suitability Model” (GISM) is based on a multi-criteria decision analysis approach and is similar in structure to land suitability analysis. The model considers a range of socioeconomic, biophysical and environmental factors to prioritize the need for UGI across the case-study region. Resulting suitability maps identify areas for multifunctional UGI localization in places where benefits can be maximized. The GISM has potential as a tool to support future planning for multifunctional UGI.

Published: November 2020

This research aimed to study the applicability and limitations of a distributed hydrological model under discontinuous steep topography and hydrogeological conditions. Based on GIS spatial analysis, typical cases of steep and gentle terrains were selected to construct the distributed hydrological model framework of the research areas (Qinhuangdao and Zhuanghe City, China). The observed runoff was used to test the applicability of the model in different terrain watersheds and to analyze the versatility of the model structure and the relevant parameters of the core modules. The results show that: in the process of using a distributed hydrological model to build models for different regions, problems such as a discontinuous dislocation of the empty area and poor connectivity of the water system will appear in the process of sub-basin division of a steep terrain. By determining the optimal threshold, selecting the best node, discontinuous dislocation, void fusion and other methods, we put forward the corresponding solutions to the problems in the division process and constructed the research area’s distributed hydrological model. The rainfall–runoff process in the study area was simulated accordingly, and the SUFI2 algorithm was used to calibrate the relevant parameters in the model. The relative error (Re), correlation coefficient (R2) and Nash–Sutcliffe efficiency (NSE), which meet the runoff accuracy in the study area, were obtained. The model verification results show that the NSE of steep terrain is 0.90, and R2 is 0.98; the NSE of gentle terrain is 0.91, and R2 is 0.984: the simulation values fit the measured values well, which makes the calibrated model suitable for both steep and gentle terrains. The results can provide a reference for the construction of a distributed hydrological model in watersheds with different terrain.
IT Adoption and Sustainable Growth of Firms in Different Industries—Are the Benefits Still Expected?
Authors: Oh Inha , Shim Dongnyok
Published: November 2020

This study uses data from the Korea business activity survey panel from 2008 to 2016 to examine the effects on the sustainable growth of firms that initially adopted Information Technology (IT) applications during 2010 to 2012 compared to those that did not. The effects are examined for four years after adoption and divided into areas such as sales, labor productivity, profitability, increases in male and female employment, wages, and exports. Because the effects of IT adoption are known to vary greatly depending on the industry, the manufacturing industry is divided into traditional, medium-tech, and hi-tech manufacturing, and the service industry is divided into the materials service and information service sectors; the effects on each sector are then observed. In addition, the propensity score matching methodology is used to overcome selection bias arising from a simple comparison between firms that began using IT and firms that did not. The results show that, although there was little impact on productivity, there were impacts on sales and employment and large differences were found between the industrial sectors.
Blockchain and Healthcare: Opportunities and Prospects for the EHR
Authors: Capece Guendalina , Lorenzi Francesco
Published: November 2020

Health protection has always been a primary concern for mankind. Despite its important social role, current systems for managing the health records are slow, complicated, sometimes expensive and exposed to human errors and misunderstandings. In the health sector, the Medicalchain project seems to have the potential to become a new standard for managing health records using blockchain technology as a platform. In this paper, we propose a new model consisting of a permissioned blockchain to manage and store the electronic health records (EHR) of registered patients. This system guarantees transparency and especially immutability, which are essential for secure management and storage, ensuring a system that is efficient both for doctors and patients and, hopefully, bringing about renewed trust in the public health system. Our aim is that our work may contribute to gain momentum on the application of the blockchain technology to EHR and stimulate further discussion with health institutions to fully exploit the potential of the technology.
Tourism Accessibility and Its Impact on the Spiritual Sustainability of Sacred Sites
Authors: Aulet Silvia , Duda Tomasz
Published: November 2020

Religious heritage sites are defined by their nature, both religious and non-religious (historical, social, cultural, etc.), as being pilgrimage destinations, as well as tourist attractions. The main aim of this paper is to determine whether there is a relationship between tourism accessibility and the concept of spiritual sustainability. Spiritual sustainability is presented in the paper by analyzing the concept of a sacred place and the connection it may have with tourism development. The authors have attempted to distinguish the elements determining the tourist and religious (spiritual) attractiveness of several pilgrimage sites as destinations for religious tourism, proposing a model for analyzing the connection between the two concepts studied. Two European regions have been compared—Pomerania (Poland) and Catalonia (Spain)—by analyzing 30 sacred sites (15 per region) using a combination of qualitative and quantitative research methods. The results show that a lack of accessibility positively affects the spiritual sustainability of the sites. In other cases, the impact that accessibility can have depends on the management system.
Evaluating the Effectiveness of Picture-Based Agricultural Extension Lessons Developed Using Participatory Testing and Editing with Smallholder Women Farmers in Nepal

Published: November 2020

Printed pictures are traditional forms of agricultural extension for smallholder farmers. They receive historical academic criticism but remain inexpensive, do not require technical skills (unlike smartphones), and bypass language/literacy barriers. Here, a comprehensive participatory pipeline is described that included 56 Nepalese women farmer editors to develop 100 picture-based lessons. Thereafter, the Theory of Planned Behavior is used as a framework to evaluate 20 diverse lessons using quantitative and qualitative data (Nvivo-11) collected from four groups, focusing on low-literacy women: the women farmer editors (n = 56); smallholder field testers who had prior exposure to extension agents and the actual innovations (control group, n = 120), and those who did not (test group, n = 60); expert stakeholders (extension agents/scientists, n = 25). The expected comprehension difference between farmer groups was non-substantive, suggesting that the participatory editing/testing approaches were effective. There were surprising findings compared to the academic literature: smallholders comprehended the pictures without the help of extension agents, perhaps because of the participatory approaches used; children assisted their mothers to understand caption-based lessons; the farmers preferred printed pictures compared to advanced information and communication technologies (ICTs); and the resource-poor farmers were willing to pay for the printed materials, sufficient to make them cost-neutral/scalable. These findings have implications for smallholder farmers beyond Nepal.
Smart-Guided Pedestrian Emergency Evacuation in Slender-Shape Infrastructure with Digital Twin Simulations
Authors: Han Tianran , Zhao Jianming , Li Wenquan
Published: November 2020

Rapid exploitation of city underground space has led to the development of increasingly more underground slender-shape infrastructure like pedestrian tunnels, concourses, subway walkways, underground shopping streets, etc. Pedestrian evacuation in those public places in case of emergency can be disastrous if not properly guided. Therefore, it is important to understand how to enhance the evacuation efficiency through proper active guidance. In this study, we propose a digital twin based guiding system for pedestrian emergency evacuation inside a slender-shape infrastructure, aiming at enhancing the overall evacuation efficiency. Composition and calibration process of the guiding system are described, and a cellular automata based model is established to serve as the digital twin model. Two guidance strategies, namely traditional fixed guidance and smart guidance, are adopted by the digital twin to generate guidance instructions. A smart guidance strategy using a semi-empirical approach is proposed based on the understanding of the free movement and congested movement of pedestrian flow. Systems under different guiding strategies are compared and discussed over their effectiveness to promote excavation efficiency in different pedestrian population distribution settings. The simulation results show that a system under smart guidance tends to have shorter evacuation time (up to 23.8% time saving) and performs with more stability for pedestrian evacuations over the traditional fixed guided systems. The study provides insight for potential real applications of a similar kind.
Opportunities and Limitations of Building Energy Performance Simulation Tools in the Early Stages of Building Design in the UK
Authors: Mahmoud Ramy , Kamara John M. , Burford Neil
Published: November 2020

This research investigates the use of Building Energy Performance Simulation (BEPS) tools in the early stages of building design in UK architectural practices with a particular focus on the barriers and opportunities to their effective application and further uptake. Two primary methods of investigation were undertaken; the first was a wide survey among UK architects and architectural practices, where the responses of 418 participants were electronically gathered and analysed. A deeper understanding of the issues was developed through an analysis of the process of low-energy building design using semi-structured interviews with six representatives of well-established architectural practices in the UK. The findings reveal that while there is an increasing understanding of the importance of BEPS involvement at the early design stages, there was limited evidence of actual early implementation of BEPS tools other than a few well known but specialised tools such as Passive House Planning Package (PHPP) which were used mainly for domestic energy performance evaluation. However, many practices surveyed showed interest in achieving higher standards than the “basic” regulatory backstops, which has resulted in Passive House and BREEAM seeing increasing use in domestic and non-domestic projects respectively. Although there has been a significant increase in the development and availability of tools and methodologies for assessing building energy performance our study shows that the focus for future research needs to be shifted from the “tool development” to looking at methods of implementing and using such tools in practice at the early design stages.
Assessing Ecological Carrying Capacity in the Guangdong-Hong Kong-Macao Greater Bay Area Based on a Three-Dimensional Ecological Footprint Model
Authors: Wang Ye-Ning , Zhou Qiang , Wang Hao-Wei
Published: November 2020

As one of the most developed and competitive metropolitan areas in the world, the contradiction between resource depletion and sustainable development in the Guangdong-Hong Kong-Macao Greater Bay Area (GHMGBA) has become a crucial issue nowadays. This paper analyzed the natural capital utilization patterns in GHMGBA during 2009–2016 based on a three-dimensional ecological footprint model. Ecological carrying capacity intensity (ECintensity) was calculated to optimize the accounting of ecological carrying capacity (EC). Ecological footprint depth (EFdepth) and ECintensity were quantitatively investigated and influencing factors were further explored based on a partial least squares (PLS) model. Results showed that GHMGBA had been operating in a deficit state due to the shortage of natural capital flow and accumulated stock depletion. The highest EFdepth occurred in Macao (17.11~26.21) and Zhongshan registering the lowest (2.42~3.58). Cropland, fossil energy and construction land constituted the most to total ecological deficit, while woodland was continuously in a slight surplus. Natural capital utilization patterns of 11 cities were divided into four categories through hierarchical clustering analysis. Driving factors of EFdepth, ECintensity and three-dimensional ecological deficit (ED3D) were mainly students in primary and secondary education, disposable income, consumption expenditure, R&D personnel and freight volume. Our findings could provide guidance for decision-makers to develop resource utilization portfolios in GHMGBA.

Published: November 2020

The Sichuan snub-nosed monkey (Rhinopithecus roxellana) is a typical arboreal group-living Old-World primate and has been studied broadly in hand preference. However, infants have not been tested independently from other immature individuals to date. The purpose of the present study was to investigate hand preference in a spontaneously unimanual feeding task in nine infants at 12 months and the relationship of hand preference with their parents in R. roxellanae. Most infants (89%) showed individual-level hand preference. No correlation was found in the direction of hand preference between infant and its parents, and a significant negative correlation in the strength of hand preference was found between infants and their mothers (r = −0.715, p = 0.03). Moreover, there was no sex difference in the direction and strength of hand preference both in infants and adults (i.e., parents). Meanwhile, the strength of hand preference in adults was stronger than that in infants. This study is a first and preliminary exploration for the expression of hand preference in R. roxellanae infants and whether their hand preference was influenced by familial inheritance.

Published: November 2020

This paper proposes a further development of the mathematical theory of swarms to behavioral dynamics of social and economic systems, with an application to the modeling of price series in a market. The complexity features of the system are properly described by modeling the asymmetric interactions between buyers and sellers, specifically considering the so-called cherry picking phenomenon, by which not only prices but also qualities are considered when buying a good. Finally, numerical simulations are performed to depict the predictive ability of the model and to show interesting emerging behaviors, as the coordination of buyers and their division in endogenous clusters.

Published: November 2020

The employment of natural substances such as beehive products with a preventive and therapeutic purpose has been a widespread custom since ancient times. In this investigation, the antibacterial activity of 41 honey samples from different Ukraine regions has been evaluated. For each honey, melissopalynological and physico-chemical analysis were performed in order to determine botanical origin, pH, glucose and fructose contents and free acidity. So, antibacterial activity against Staphylococcusaureus CCM 4223, Listeria monocytogenes ATCC 7644, Salmonella enterica serovar Typhimurium CCM 3807 and Escherichia coli ATCC 25922 was assessed through the determination of MIC (Minimum Inhibitory Concentration) and MBC (Minimum Bactericidal Concentration) values by the microdilutions method. The results show that the most susceptible bacterial strain was L. monocytogenes. Its growth was inhibited at a honey concentration ranging from 0.094 to 0.188 g/mL. The most resistant bacterial strain was S. aureus. As concerns MBC values, L. monocytogenes was the most susceptible bacteria, while S. aureus was the most resistant. Helianthus spp. honeys was the most effective against all tested bacterial strains, followed by Robinia spp. and multifloral honeys. Promising results for MIC tests have been found for Brassica spp.

Published: November 2020

Pyometra is considered the most common disease in intact bitches, being associated with potentially life-threatening disorders. Myocardial damage is a potentially life-threatening consequence of pyometra. The aim of this study was to describe the electrocardiographic patterns in bitches affected by closed cervix pyometra, to assess the clinical relevance of electrocardiographic changes with the occurrence of pyometra, and to relate their severity with laboratory and clinical findings. A total of 39 bitches with closed cervix pyometra and 10 healthy female dogs were included in this study. During the hospitalization, bitches underwent a complete physical examination. An electrocardiographic examination before the ovariohysterectomy was performed. Blood samples for biochemical and hematological analysis were also evaluated. Bitches suffering pyometra at least one arrhythmia 31/39 (79.4%), sinus tachycardia (22/39, 56.4%), ventricular premature complexes (9/39, 23%), increased amplitude of T wave (7/39, 17.9%), ST depression (4/39, 10.2%), second-degree atrioventricular block (2/39, 5.1%), increase of QT interval (2/39, 5.1%), sinus bradycardia (2/39, 5.1%), and first-degree atrioventricular block (1/39, 2.5%). Some bitches were also detected with low wave amplitude (17/39, 43.5%). Cardiac arrhythmias associated with canine pyometra are frequent events. These data suggest that arrhythmias may be the consequence of one or more factors that can occur during pyometra, such as myocardial damage, electrolyte/metabolic disorders, and/or sepsis.

Published: November 2020

Introdução: O Programa Restaurante Popular tem como objetivo ofertar refeições saudáveis e a preços acessíveis, reduzindo assim, o número de pessoas em situação de insegurança alimentar. Objetivo: Verificar a qualidade nutricional, sensorial e o tipo de processamento dos alimentos utilizados no preparo das refeições de um restaurante popular do município de Belo Horizonte/MG. Materiais e Métodos: Estudo de caso descritivo e de caráter qualitativo. Foi avaliada a qualidade nutricional e sensorial das refeições servidas no período de fevereiro a maio de 2018 através do método Avaliação Qualitativa das Preparações do Cardápio. Os critérios avaliados foram frequência de folhosos, frutas, doces, cores iguais, alimentos ricos em enxofre, carne gordurosa, fritura e doce associado à fritura. Os cardápios foram então classificados em ótimo, bom, regular, ruim ou péssimo. O tipo de processamento dos alimentos utilizados no preparo das refeições foi avaliado de acordo com as recomendações do Guia Alimentar para a População Brasileira. Resultados: Os cardápios foram classificados como bom pela oferta de folhosos (89,3%), preparações com cores iguais (10,7%) e frituras (10,7%); regular para a presença de frutas (57,1%), doces (42,9%), preparações ricas em enxofre (27,4%) e carnes gordurosas (26,2%); e ótima pela oferta de doces associados a frituras (0%). A maioria dos ingredientes utilizados era in natura ou minimamente processados (75,6%), o per capita médio de óleo/gordura foi adequado (8,3 mL), mas o de sal foi elevado (7 gramas). Conclusão: O cardápio ofertado no restaurante popular apresentou boa qualidade sensorial e atendeu em parte às recomendações alimentares preconizadas pelo Guia Alimentar para a População Brasileira. Desta forma, é necessário a revisão de suas técnicas de preparo para reduzir a quantidade de sal e gorduras ultraprocessadas utilizadas para assim proporcionar a oferta de refeições nutricionalmente adequadas às pessoas socialmente vulneráveis ou que se alimentam fora de casa.

Introdução: No início de 2015 foram detectadas as primeiras infecções do vírus Zika no Nordeste do Brasil e no final do mesmo ano constatou-se a sua propagação para pelo menos quatorze estados brasileiros, incluindo Minas Gerais. Objetivo: Descrever o perfil epidemiológico dos casos de infecção por vírus Zika em Juiz de Fora, com foco especial nas gestantes infectadas. Materiais e Métodos: Dados referem-se ao período de janeiro de 2016 a junho de 2019, da cidade de Juiz de Fora obtidos através do Departamento de Vigilância Epidemiológica e Ambiental, do Sistema de Informação de Agravos de Notificação e do Registro de Eventos em Saúde Pública (RESP). Foram extraídos: data das notificações, idade, sexo, período de gravidez, raça, nível de escolaridade, se a infecção foi autóctone, bairro de residência e critério utilizado para confirmação da infecção. Resultados: 288 casos tiveram a confirmação através de exames laboratoriais (RT-PCR), sendo 19 gestantes. Não houve registro de óbitos ou abortos pela infecção. Em 13 dos 19 casos em gestantes, o RESP não foi completamente preenchido. A média de idade foi 36,69 ±17,81 anos, 68,05% do sexo feminino, e o nível de escolaridade predominante foi fundamental incompleto e médio completo. Conclusão: Apesar dos dados incompletos nos sistemas de notificações, foi identificada maior taxa de infeção no sexo feminino, na faixa etária de 20 a 49 anos.

Introdução: Na prática e pesquisa é cada vez mais presente o uso de tecnologias que auxiliam o trabalho dos profissionais, como o geoprocessamento, útil para investigar variáveis espaciais de determinado fenômeno, quando se busca averiguar dados, a partir de ferramentas geoestatísticas. Objetivo: Analisar a distribuição espacial de pacientes atendidos no setor emergência de hospital terciário. Material e Métodos: Estudo transversal, realizado de julho a setembro de 2017, na emergência de hospital terciário, com 783 fichas de atendimento/prontuários. A análise espacial foi realizada com o software Quantum GIS 2.18.10. Resultados: A maioria dos atendimentos foi do sexo masculino (63,9%), com idade média de 52 anos. Os procedentes das cidades circunvizinhas (75,6%) possuíram classificação de risco, predominantemente, nas cores amarela e vermelha, enquanto a classificação nas cores verde e amarela prevaleceu dentre os pacientes do mesmo município de localização do hospital. Os atendimentos ocorreram a pacientes oriundos da região norte do estado do Ceará, com maior densidade nos municípios da macrorregião de Sobral, entretanto, houve atendimentos a pacientes de Fortaleza e sertão do estado. Conclusão: A distribuição espacial aponta que os atendimentos do setor de emergência contemplaram pacientes do norte do estado do Ceará, sertão e região metropolitana da capital do estado. A densidade de atendimentos e classificação de risco nas cores azul e verde foi diretamente proporcional à proximidade geográfica com o hospital, enquanto as cores amarela e vermelha possuíram relação inversamente proporcional com tal distância.
O Cancioneiro de Clínia: epigramas amorosos de Jean Visagier em tradução poética
Authors: Da Cunha Lima Ricardo
Published: November 2020

Jean Visagier, membro do círculo humanístico de Lyon, publicou quatro obras em latim, dedicadas ao gênero epigramático, entre os anos de 1536 e 1538. Obediente às normas clássicas do epigrama, compôs a grandemaioria deles em dístico elegíaco. A temática é muito variada, como é característico no gênero. Deixando de lado os epigramas encomiásticos e vituperiosos, a presente tradução se concentra em um conjunto de 30 epigramas amorosos, nos quais aparece como personagem central uma puella, chamada Clínia, que serve para representar as mais diversas cenas do relacionamento amoroso, tal como na elegia erótica romana. A forte tradição da Antiguidade, por outro lado, também é modulada por conceitos trovadorescos e petrarquistas. A tradução foi feita em versos metrificados. No caso do dístico elegíaco, optou-se por um dístico composto por um verso dodecassílabo e um decassílabo.
Do “povo amorfo” ao populismo. A trajetória do conceito de populismo nas ciências sociais brasileiras.
Authors: Gentile Fábio
Published: November 2020

Este artigo pretende fornecer um panorama analítico, histórico-crítico e metodológico, embora não exaustivo, dos usos do conceito de populismo nas ciências sociais brasileiras. A hipótese central, sustentada no trabalho, é que, embora não seja possível individuar uma verdadeira teoria do populismo brasileiro na década de 1920 e 1930, é necessário reconhecer que o conceito de “povo amorfo” elaborado pelos teóricos do Estado autoritário varguista abriu o caminho para o uso do conceito de populismo na análise dos processos de modernidade-modernização brasileira do século XX.
Soft Power Mineiro
Authors: Gomes de Castro Vanessa , Rodrigues Tavares Thiago
Published: November 2020

O presente artigo analisa os resultados do edital Circula Minas de Intercâmbio Cultural, do ano de 2015 a 2018, com atenção especial à área de patrimônio. Os editais, amparados em políticas culturais e sociais, tiveram por finalidade apoiar financeiramente artistas, pesquisadores, mestres dos saberes tradicionais e afins, domiciliados no estado de Minas Gerais, em viagens para apresentação e capacitação em diversas áreas culturais, visando à difusão nacional e internacional da cultura mineira, bem como a sua preservação. Diante disso, busca-se refletir sobre os editais, considerando o conceito de soft power, entendido como a construção de relações de poder amistosas, por exemplo, através de políticas culturais, fortalecendo, assim, o poder político e econômico dentro e fora do país, pela atratividade cultural. Os resultados são apresentados em tabelas, contendo a quantidade de propostas selecionadas por ano, as áreas culturais contempladas, o valor do apoio financeiro, as cidades de origem e os países de destino. As conclusões enfatizam os potenciais retornos de medidas como os referidos editais, na promoção e proteção da cultura e do patrimônio do estado, fortalecendo o soft power mineiro e brasileiro.
