Published: March 2021

Achieving multiple physical properties from a single material through three-dimensional (3D) printing is important for manufacturing applications. In addition, industrial-level durability and reliability is necessary for realizing individualized manufacturing of devices using 3D printers. We investigated the properties of architected materials composed of ultraviolet (UV)-cured urethane elastomers for use as insoles. The durability and reliability of microlattice and metafoam architected materials were compared with those composed of various foamed materials currently used in medical insoles. The hardness of the architected materials was able to be continuously adjusted by controlling the design parameters, and the combination of the two materials was effective in controlling rebound resilience. In particular, the features of the architected materials were helpful for customizing the insole properties, such as hardness, propulsive force, and shock absorption, according to the user’s needs. Further, using elastomer as a component led to better results in fatigue testing and UV resistance compared with the plastic foam currently used for medical purposes. Specifically, polyethylene and ethylene vinyl acetate were deformed in the fatigue test, and polyurethane was mechanically deteriorated by UV rays. Therefore, these architected materials are expected to be reliable for long-term use in insoles.

Published: March 2021

The Tactile Internet will require ultra-low latencies for combining machines and humans in systems where humans are in the control loop. Real-time and perceptual coding in these systems commonly require content-specific approaches. We present a generic approach based on deliberately reduced number accuracy and evaluate the trade-off between savings achieved and errors introduced with real-world data for kinesthetic movement and tele-surgery. Our combination of bitplane-level accuracy adaptability with perceptual threshold-based limits allows for great flexibility in broad application scenarios. Combining the attainable savings with the relatively small introduced errors enables the optimal selection of a working point for the method in actual implementations.

Published: March 2021

A series of sky surveys were launched in search of supernovae and generated a tremendous amount of data, which pushed astronomy into a new era of big data. However, it can be a disastrous burden to manually identify and report supernovae, because such data have huge quantity and sparse positives. While the traditional machine learning methods can be used to deal with such data, deep learning methods such as Convolutional Neural Networks demonstrate more powerful adaptability in this area. However, most data in the existing works are either simulated or without generality. How do the state-of-the-art object detection algorithms work on real supernova data is largely unknown, which greatly hinders the development of this field. Furthermore, the existing works of supernovae classification usually assume the input images are properly cropped with a single candidate located in the center, which is not true for our dataset. Besides, the performance of existing detection algorithms can still be improved for the supernovae detection task. To address these problems, we collected and organized all the known objectives of the Panoramic Survey Telescope and Rapid Response System (Pan-STARRS) and the Popular Supernova Project (PSP), resulting in two datasets, and then compared several detection algorithms on them. After that, the selected Fully Convolutional One-Stage (FCOS) method is used as the baseline and further improved with data augmentation, attention mechanism, and small object detection technique. Extensive experiments demonstrate the great performance enhancement of our detection algorithm with the new datasets.

Authors: Biliszczuk Jan , Hawryszków Paweł , Teichgraeber Marco
Published: March 2021

The Rędziński Bridge in Wrocław is the biggest Polish concrete cable-stayed bridge. It is equipped with a large structural health monitoring (SHM) system which has been collecting the measured data since the bridge opening in the year 2011. This paper presents a comparison between the measured data and the finite element method (FEM) calculations, while taking into account 7 years of data collection and analyses. The first part of this paper concerns the SHM application. In the next part, which contains comparisons between forces in cables and temperature changes throughout the structure, the measured data are presented. The third part includes SHM-based calculations and simulations with a complex FEM model to check the measured data and to estimate future measurements. The last part contains a durability assessment calculation for the cable stays.
Green Shooting: Media Sustainability, A New Trend
Authors: Lopera-Mármol Marta , Jiménez-Morales Manel
Published: March 2021

Research on media sustainability has a long tradition of criticising climate change and environmental issues, mainly through content, and while it is important to do so, it seems that the sector is oblivious to the impact that it itself generates. Moreover, sustainability is often (and wrongly) only related to environmental impact, and very little research exists on how the audio-visual sector can be sustainable not only from an environmental standpoint, but also from a socio-cultural and economic one. This article constitutes a relatively new area that has emerged from the notion of Green Shooting, a term used to describe all the practices ranging from the pre-production, production and post-production to the publicising of an audio-visual product: Documentary, television series (including those of streaming platforms), videogame, film, festival or an advertisement. There has been little previous evidence of an academic article that brings together all the practices that several companies and initiatives worldwide have already implemented as emerging solutions to mitigate their impact, including new roles such as eco-assistant. The authors aim to develop an overarching theoretical framework of what already exists in the practical field, and make it available to the academic community.
A Parametric Approach for Determining Fishway Attraction Flow at Hydropower Dams
Authors: Heneka Patrick , Zinkhahn Markus , Schütz Cornelia , Weichert Roman B.
Published: March 2021

High discharges at hydropower plants (HPP) may mask fishway attraction flows and, thereby, prevent fishes from locating and using fishways critical for their access to upstream spawning and rearing habitats. Existing methods for determining attraction flows are either based on simple guidelines (e.g., a proportion of HPP discharge) that cannot address the spatial and temporal complexity of tailrace flow patterns or complicated studies (e.g., combinations of detailed hydraulic and biological investigations) that are expensive and time-consuming. To bridge this gap, we present a new, intermediate approach to reliably determine attraction flows for technical fishways at small to medium-sized waterways (mean annual flow up to 400 m3/s). Fundamental to our approach is a design criterion that the attraction flow should maintain its integrity as it propagates downstream from the fishway entrance to beyond the highly turbulent zone characteristic of HPP tailraces to create a discernable migration corridor connecting the fishway entrance to the downstream river. To implement this criterion, we describe a set of equations to calculate the width of the entrance and the corresponding attraction discharge. Input data are usually easy to obtain and include geometrical and hydraulic parameters describing the target HPP and its tailrace. To confirm our approach, we compare model results to four sites at German waterways where the design of attraction flow was obtained by detailed experimental and numerical methods. The comparison shows good agreement supporting our approach as a useful, intermediate alternative for determining attraction flows that bridges the gap between simple guidelines and detailed hydraulic and biological investigations.
Small plate vibration sound-absorbing device with a clearance and without surrounding restriction: Theoretical analysis and experiment
Authors: Sakamoto Shuichi , Fujisawa Kouhei , Watanabe Shunsuke , Watanabe Taku , Kominami Ryota , Akiba Yuki
Published: March 2021

This article focuses on the theoretical analysis and experiment of a small plate vibration sound-absorbing device with a clearance and without surrounding restriction. Generally, a plate vibration sound-absorbing device absorbs sound in a frequency range lower than that of porous material,
which is used as a sound-absorbing material, and its sound absorption coefficient is small. Furthermore, note that the plate is fixed at the periphery in a conventional plate vibration sound-absorbing device. Hence, when the plate is small, vibration barely occurs and effective sound-absorbing
effect is not obtained. Given that the plate vibration sound-absorbing device has a restriction wherein a particular size of plate is required, it is primarily utilized for indoor finishing considering the architectural acoustics, and finding applications for small-sized machines has been
challenging. Theoretical values in this work are calculated assuming that the clearance and back air layer for the small plate vibration sound-absorbing device constitute a Helmholtz resonator. Furthermore, experiments were conducted to perform comparisons against the theoretical value. The
theoretical analysis was conducted by connecting the clearance and back air layer in parallel with the plate portion in the electrical equivalent circuit. By performing the experiments using various parameters, the sound absorption characteristics of the proposed plate vibration sound-absorbing
device were determined. If the clearance is smaller than the boundary layer thickness, then the conventional resistive end correction cannot be applied.
Exploring commissioners’ understandings of early primary care network development: qualitative interview study
Authors: Warwick-Giles Lynsey , Hammond Jonathan , Bailey Simon , Checkland Kath
Published: March 2021

Background

Primary care networks (PCNs) are financially incentivised groupings of general practices in the English NHS. Their purpose is to deliver a number of policy goals set out in The NHS Long Term Plan. Clinical commissioning groups (CCGs) have a role in their establishment, support, and oversight.

Aim

To explore commissioners’ perspectives on the early development of PCNs.

Design and setting

Qualitative study of CCG staff using telephone interviews.

Method

Semi-structured interviews were carried out with 37 CCG employees involved in PCN establishment. Interviewees were asked about local PCNs’ characteristics, factors shaping development and form, activities to date, challenges and benefits, and their CCGs’ relationship with PCNs. Interviewee responses were summarised within a matrix and analysed thematically.

Results

Three meta-themes were identified: the multifaceted role of the commissioner, tensions between PCN policy and locally commissioned services, and engaging the broader system. Interviewees reported that the policy potentially favours those PCNs working from a ‘blank slate’ and does not sufficiently account for the fact some GP practices and wider system organisations have been doing similar work already. The prescriptive, contractual nature of the policy has led to local challenges, trying to ensure that local good practices are not lost during implementation. Interviewees also considered an important part of their work to be protecting PCNs from the weight of expectations placed on them.

Conclusion

CCGs are well placed to understand the complexities of local systems and to facilitate PCNs and working practices between wider system partners. It is important that this local role is not lost as CCGs continue to merge and cover larger geographical populations.

Authors: Hajinezhad Mohammad Reza , Hajian Shahri Shaghayegh , Rahdar Abbas , Zamanian Hojjat
Published: March 2021

Background: The present study was conducted to investigate the potential protective effect of cerium oxide nanoparticles (CeNPs) against lead acetate-induced toxicity. Materials and Methods: In this study, 30 adult male Wistar rats were randomly divided into three groups and treated simultaneously, except for the normal control, for 5 weeks with lead acetate in drinking water (1000 mg/L). Control rats and negative control rats received saline intraperitoneally. At the same time, the third group was treated with intraperitoneal injections of CeNPs at the dose of 0.5 mg/kg 1 week before lead administration, and continued with its administration. Finally, serum was obtained by the conventional methods and rats were sacrificed to obtain liver, heart, testis, and kidney tissue for histopathological examinations. Results: The lead-treated group showed significant increases in blood urea nitrogen (BUN), serum creatinine, serum aspartate aminotransferase (AST), serum alanine aminotransferase (ALT), and malondialdehyde (MDA) levels (P<0.01). Lead-intoxicated rats treated with CeNPs showed a significant decrease in serum lactate dehydrogenase (LDH), AST, and ALT levels compared to the untreated negative control group (P<0.01). The histopathological examination of liver and kidney tissues showed signs of lead-induced injuries, necrotic hepatocytes, and glomerulosclerosis. The CeNPs-treated group showed noticeable reductions in histopathological signs of lead-induced injuries. Lipid peroxidation levels were also lower in CeNPs-treated rats than negative controls (P<0.05). Conclusion: The current experimental study proved the protective effects of CeNPs in rats exposed to chronic lead-induced toxicity; however, more experiments are required to evaluate the possible side effects and interactions.

Published: March 2021

Background: A hydatidiform mole or molar pregnancy is the most prevalent gestational trophoblastic disease (GTD). About 55%-60% of women with trophoblastic diseases have overt hyperthyroidism at the time of diagnosis, which may have severe manifestations. This study examined the relationship between gestational hypertension and the level of thyroid hormones with beta human chorionic gonadotropin (β-HCG) in patients with a hydatidiform mole. Materials and Methods: This cross-sectional study enrolled 65 patients with a hydatidiform mole admitted to Khalij-e Fars hospital, Bandar Abbas, Iran. Patients were divided into three groups of clinical hyperthyroidism, subclinical hyperthyroidism, and healthy. The serum levels of thyroid-stimulating hormone (TSH), T4, T3, and β-HCG were checked in all subjects, and the relationship between gestational hypertension and the level of thyroid hormones with β-HCG in patients with a hydatidiform mole was examined. Results: The mean age of patients was 29.93 ± 9.04 years, and their mean gestational age was 11.09 ± 4.2 weeks. In this study, 12.3% of the patients had subclinical hyperthyroidism, 41.5% had clinical hyperthyroidism, and 46.2% were healthy. A significant relationship was found between the serum level of β-HCG and thyroid function in patients with clinical and subclinical hyperthyroidism compared to the healthy group (P= 0.001). No significant relationship was found between systolic/ diastolic blood pressure and the serum level of β-HCG. Conclusion: A significant relationship was observed between the serum levels of β-HCG and TSH, free T3, and free T4 in patients with a hydatidiform mole and thyrotoxicosis. Thus, early diagnosis of hyperthyroidism can help treat these patients more quickly.

Published: March 2021

Background: Diaper dermatitis (DD) is a prevalent skin disease in children, which causes child discomfort and parental concern. This study aimed to compare the effects of aloe vera ointment with routine treatment on the severity of DD in hospitalized children. Materials and Methods: This double-blinded randomized clinical trial was carried out on 60 children aged less than two years admitted to Tabriz pediatric hospital in Iran from February to June 2017. Using convenience sampling method, the patients were assigned into two equal groups (n=30 in each) of intervention and control. The intervention group received routine combination treatment, whereas the control group received aloe vera ointment. The patients were examined on the first, third, and sixth days of the study. Data analysis was performed using SPSS software (version 22) and descriptive and analytical statistics. Results: The severity of DD in both groups improved on the sixth day compared to the first day. In comparison, no significant difference was observed between the two groups regarding the severity of dermatitis (P>0.05). Conclusion: Herbal products cause fewer side effects than chemical products and seem to have significant pharmacological effects on the skin. Thus, aloe vera ointment appears to help treat DD and, with further studies, may emerge as a possible therapeutic option.

Published: March 2021

Background: The present study aimed to investigate the relationship between the serum vitamin D level and the severity of bronchiolitis in infants. Materials and Methods: The population of this descriptive-analytical study included all infants within the age range of 1 month to 24 months old with bronchiolitis hospitalized in Bandar Abbas children’s hospital in 2018-2019. According to the exclusion and inclusion criteria, patients were entered in the study and diagnosed with bronchiolitis by a pediatric infectious disease specialist. Then, their serum levels of vitamin D were measured as well. Results: Of the 85 patients, 62.4% and 37.6% were males and females, respectively. The mean serum level of vitamin D was 29.74±13.44 ng/mL. In addition, the mean age in groups with mild-, moderate-, and severe-intensity was 9.27±4.52 months, 5.12±3.95 months, and 3.16±1.16 months (P<0.001), respectively. Further, the Spearman’s correlation between age and serum vitamin D levels was r = 0.05 (P<0.001). Based on the results, there was a statistically significant difference between the mean age in the two study groups (P<0.001). Finally, a statistically significant association was found between the severity of bronchiolitis and vitamin D status (P=0.007). Conclusion: According to the results of the present study, more than half of the infants admitted to the diagnosis of bronchiolitis had insufficient serum levels of vitamin D. There was also a significant association between the severity of bronchiolitis and serum vitamin D levels.

Authors: Almousa Samaher , Suleiman Ammar , Mohsen Samer
Published: March 2021

Background: A recent ongoing pandemic of coronavirus disease named coronavirus disease 2019 (COVID-19) has spread in Syria from March 2020 with a pattern of a slow case increase. So far, the government has put the country under lock-down orders as a preventive measure. However, there is a considerable belief in the medical community of our country supposes that the virus has previously passed through the country depending on the high numbers of diagnosed severe respiratory infections early in 2020. Thus, this study was designed to determine the number of people with detectable antibodies to SARS-CoV-2 from two samples of healthy adults with and without a previous history of severe respiratory infection in the last 6 months of the study. Materials and Methods: To this end, samples were collected from 123 and 198 subjects with a previous severe respiratory infection and healthy controls, respectively. Then, immunoglobulin M (IgM) and IgG anti-SARS-CoV-2 antibodies were tested as well. Results: None of the samples from both groups tested IgG positive in the assay while four tested IgM samples were positive. Accordingly, these positive samples were re-analyzed and remained IgM positive in the second test although the reverse transcriptase-polymerase chain reaction for the SARS-CoV-2 virus was negative. Conclusion: Based on our findings, there is no evidence concerning the previous COVID-19 infection in Syria thus it is suggested that all isolation and lock-down orders should be respected as an effective preventive tool in this regard.

Published: March 2021

Background: Alzheimer’s disease (AD) is the most common brain failure for which no cure has yet been found. The disease starts with a disturbance in the brain structure and then it manifests itself clinically. Therefore, by timely and correct diagnosis of changes in the structure of the brain, the occurrence of this disease or at least its progression can be prevented. Due to the fact that magnetic resonance imaging (MRI) can be used to obtain very useful information from the brain, and also because it is non-invasive, this method has been considered by researchers. Materials and Methods: The data were obtained from an MRI database (MIRIAD) of 69 subjects including 46 AD patients and 23 healthy controls (HC). Individuals were categorized based on two criteria including NINCDS-ADRAD and MMSE, as the gold standard. In this paper, we used the support vector machine (SVM) and Bayesian SVM classifiers. Results: Using the SVM classifier with Gaussian radial basis function (RBF) kernel, we distinguished AD and HC with an accuracy of 88.34%. The most important regions of interest (ROIs) in this study included right para hippocampal gyrus, left para hippocampal gyrus, right hippocampus, and left hippocampus. Conclusion: This study showed that the SVM model with Gaussian RBF kernel can distinguish AD from HC with high accuracy. These studies are of great importance in medical science. Based on the results of this study, MRI centers and neurologists can perform AD screening tests in people over the age of 50 years.

Authors: Ibrahim Ilham Khalid , Hassan Fatiheea Fatihalla , Abdulkareem Nashwan Karkhi
Published: March 2021

Background: In conventional X-ray examinations, patients are exposed to radiation. Biological hazards from radiation of any source is expressed as effective dose, and is measured in millisieverts (mSv). The purpose of this study was to assess and calculate the effective dose values for patients undergoing posteroanterior (PA) chest, abdomen, anteroposterior (AP) pelvis, and cervical spine X-ray examinations in general hospitals of Erbil city and compare it with those of other studies. Materials and Methods: A total of 255 patients between 20-70 years of age participated in this work (85 per hospital). The patients’ characteristics included age, sex, examination type, projection posture, and exposure parameters captured by NOMEX Multimeter including tube potential and current-time product. The mean effective doses (EDs) of four different examinations (chest (PA), pelvis (AP), abdomen, and cervical spine) were measured using the Monte Carlo method and compared with those of other studies. Results: The mean EDs were calculated 1.04, 2.01, 3.12, and 3.22 mSv for chest (PA), pelvis (AP), abdomen, and cervical spine, respectively. All ED values in this study were higher than those of published studies. The aim of the study was to increase the awareness of the radiographer and patients undergoing conventional X-ray diagnostic radiology on the risk of ionizing radiation for radiological protection in Erbil hospitals. Conclusion: The mean EDs were increased by an increase in the age; this may increase the probability of cancer incidence and heritable diseases. Hence, dose optimization is required due to more probable incidence of cancer when compared to other studies.

Published: March 2021

Background: Tramadol is a synthetic drug with central mechanisms which binds to µ-opioid receptors. Recently, increased consumption and serious complications have been reported about this drug. Thus, the aim of this study was to determine the frequency of tramadol toxicity in Shahid Mohammadi Hospital in Bandar Abbas. Materials and Methods: This retrospective descriptive study was performed on individuals with tramadol toxicity admitted to Shahid Mohammadi Hospital, Bandar Abbas during 2013- 2014. Information was collected through patients’ medical files using a checklist including demographic characteristics, toxicity complications, and patients’ clinical outcomes. The acquired data were then analyzed using SPSS software. Results: The mean age of 53 patients was 24.71±7.76 years, of which 69.8% were males and 49.1% had a history of drug abuse. In addition, the seizure was observed in 49.1% of them, and 47.2% of cases simultaneously used another drug, along with tramadol. Further, the history of mental disorders was reported in 24.5% of patients. Clinical manifestations included a decreased level of consciousness (49.1%), nausea and/or vomiting (45.3%), and headache (30.2%). Furthermore, the duration of hospital stay was 48 hours in 90.6% of patients. Eventually, a significant correlation was found between seizure and drugs other than tramadol (P=0.001), gender (P=0.004), and occupation (P=0.010). Conclusion: Most cases of tramadol toxicity occur in students and young adults, resulting in complications such as seizure, decreased levels of consciousness, and nausea and/or vomiting. Accordingly, awareness of the complications of tramadol and meticulous observations over its methods of delivery could reduce the associated harms.

Improving norms in research culture to incentivize transparency and rigor
Authors: Mellor David Thomas
Published: March 2021

Improving research culture to value transparency and rigor is necessary to engage in a productive “Credibility Revolution.” The field of educational psychology is well positioned to act toward this goal. It will take specific actions by both grassroots groups plus leadership to set standards that will ensure that getting published, funded, or hired is determined by universally supported ideals. These improved standards must ensure that transparency, rigor, and credibility are valued above novelty, impact, and incredibility. Grassroots groups advocate for change and share experience so that the next generation of researchers have the experience needed to sustain these early moves. Each community can take inspiration from others that have made shifts toward better practices. These instances provide opportunities for emulating trail-blazers, training for new practices such as preregistration, and constructively evaluating or criticizing practice in ways that advances the reputation of all involved.

En este contexto, la educación enfrenta nuevos retos y desafíos que no sólo estarán permeados por la enseñanza de aprendizajes cognitivos, sino por otros aprendizajes emocionales que promuevan la formación integral del ser humano como se establece en los principios filosóficos de la educación mexicana. La presente investigación, tiene como propósito realizar un análisis teórico a partir de la revisión bibliográfica sobre las emociones y la educación socioemocional como área formativa que pretende favorecer el desarrollo armónico e integral de los estudiantes. Se hace un análisis conceptual de las emociones, la educación socioemocional y la socioformación como enfoque emergente de enseñanza que orienta la formación del individuo a partir de la resolución de problemas del contexto, el trabajo colaborativo y el desarrollo del talento humano. Los resultados concluyen que los educadores deben potenciar el desarrollo de las habilidades socioemocionales en los estudiantes para favorecer su formación integral y el despliegue de las capacidades de autoconocimiento, autorregulación y autonomía en el marco de la empatía y la colaboración.
Capoeira e inmovilidad: estrategias de resistencia y los desafíos frente a la emergencia sanitaria del COVID-19
Authors: González Varela Sergio
Published: March 2021

El presente artículo describe los principales efectos sociales que ha tenido la pandemia del COVID-19 en la práctica del arte marcial y ritual afrobrasileño de la Capoeira desde una perspectiva antropológica. El problema se centra en la inmovilidad que se ha producido dentro de los grupos como consecuencia de la emergencia sanitaria global. El texto se enfoca en las relaciones sociales que los líderes han desarrollado con sus discípulos y con académicos. La metodología usada parte de un análisis sobre las interacciones en línea que se generaron desde inicios del año 2020, en lo que en antropología se llama como etnografía virtual, a través de entrevistas con diferentes miembros y grupos de Capoeira en Brasil y México. Los resultados de esta investigación argumentan que los efectos de la inmovilidad han forzado a los líderes a priorizar la transmisión de su conocimiento, el cual se guarda normalmente en secreto, a través del Internet a partir del diálogo en foros y la impartición de clases en línea para una audiencia global. La conclusión afirma que, debido a la situación actual, los líderes han comenzado a diseminar por medios digitales sus enseñanzas como parte de un mecanismo de resistencia cultural. Obligados por la emergencia sanitaria, tanto practicantes y estudiosos de la Capoeira han comenzado a experimentar nuevas maneras de crear relaciones sociales para el contexto de inmovilidad actual.
“Mi Mestre no es brasileño”: Sobre la autenticidad y legitimidad de la capoeira en México
Authors: Contreras Islas David Sebastian
Published: March 2021

Griffith propone los marcadores de autenticidad como formas de capital cultural que permiten ganar legitimidad en el campo social de la capoeira. Entre ellos, destaca el grado de Mestre como último marcador de autenticidad/legitimidad. Pese a la globalización de la práctica, la literatura reporta la existencia de pocos Mestres no-brasileños, especialmente en las regiones del Norte Global. En este contexto, el caso de México es atípico por contar con un número equiparable de Mestres mexicanos y brasileños. Este estudio analiza las historias de vida de dos de estos Mestres mexicanos, que han sido pioneros en la formación de profesionistas de la capoeira en el país, con el objetivo de comparar sus estrategias de legitimación con las observadas por Griffith. Con ello, el presente estudio prueba el alcance analítico de la propuesta de Griffith y contribuye a un mejor entendimiento de la economía de la autenticidad de la práctica. En contraste con las observaciones de Griffith, se sugiere que la innovación puede operar como marcador carismático para ganar legitimidad, mientras que el género puede mermar la legitimidad de un/a Mestre/a, abriendo nuevas perspectivas sobre las dinámicas del campo social de la capoeira y otras prácticas similares.
La Capoeira en la era de la globalización: comprendiendo las dinámicas de sus inicios y difusión en la ciudad de Medellín (Colombia)
Authors: Montoya Nanclares Rubén Dario
Published: March 2021

Crear conciencia sobre la memoria histórica y las dinámicas que en ella se vivencian es fundamental en esta era de la globalización en la cual la Capoeira se ha difundido por diferentes lugares del mundo. Debido a la falta de información y a la diversidad de narrativas –algunas contradictorias- se emprendió un ejercicio investigativo orientado por la pregunta: ¿cómo surgió la Capoeira en la ciudad de Medellín (Colombia)? El método bajo el cual se apoyó fue la etnometodología, se utilizaron como dispositivos para la generación de la información la entrevista semiestructurada y el diario de campo, los cuales a partir de la narrativa de los participantes-protagonistas, permitió mapear diferentes acontecimientos que caracterizan la historia de esta manifestación cultural en la ciudad de Medellín-Colombia. Este zoom a uno de los lugares donde ha llegado la Capoeira, permitió mantener vigente la memoria histórica y reconocer a los protagonistas que en diferentes contextos han hecho posible su difusión; igualmente con esta experiencia se hace un aporte para comprender las dinámicas generadas en los inicios de la Capoeira en contextos por fuera de Brasil, lo cual es un referente importante para analizar las formas en que esta, ha logrado traspasar fronteras, culturas, ideologías, etc. convirtiéndose en una embajadora de la cultura afro brasilera alrededor del mundo.
Herencias corporales, un ejercicio etnográfico sobre la etnomotricidad en el juego de la Capoeira
Authors: Tobón Londoño Lina Marcela
Published: March 2021

Este artículo reflexiona e indaga por el concepto de etnomotricidad dentro de la práctica de la Capoeira, reconociendo que este concepto no está institucionalizado ni nombrado así dentro de la práctica misma. La etnomotricidad comienza a develarse en la Capoeira desde una búsqueda personal y por la necesidad de generar reflexiones ante la singularidad en el gesto motriz propio de esta arte, en su relación con la comunidad que la práctica y en sus posibles significados. Con este propósito se realiza una revisión etnográfica del concepto de etnomotricidad dentro del juego de la capoeira a través de entrevistas a algunos participantes del grupo Oficina da Capoeira Medellín, posteriormente se realizó una triangulación en el análisis con fotos del acervo, revisión teórica y el resultado de las entrevistas, permitiendo conocer las posibles mutaciones y pervivencias del gesto motriz que los practicantes reconocen en su propia experiencia como capoeiristas.
Liquid crystal lens with tunable conical lens properties
Authors: Kawamura Marenori , Ichimura Yuki , Sugawara Tomoki
Published: March 2021

A three-dimensional numerical calculation for analyzing reorientation in liquid crystal (LC) directors and optical phase retardation in an LC lens, which exhibits a tunable conical lens property, is developed. The proposed LC lens design employs a circular electrode, ring electrodes, and a circularly hole-patterned electrode employing a highly-resistive layer in a flat nematic cell. The three-dimensional tilt and azimuthal angle distributions are calculated. Subsequently, the conical phase retardation in the lens region can be estimated. The experimental results obtained for the optical phase profile agree well with the numerically calculated results.
The challenges of digital transformation: Case of Tunisian companies
Authors: Ben Hadj Hassine Amine
Published: March 2021

The objective of this article is to identify the challenges of Tunisian small and medium-sized enterprises (SMEs) in the implementation of Industry 4.0. Indeed, the Subject of Digital Transformation has its relevance as Industry 4.0 is considered as the first industrial revolution to be predicted before it happened. Competition from digital companies is disrupting business models, and leaders no longer have a choice: the time has come for digital transformation (Dussart, C, 2015). This transition is not new. It covers a necessary reality, especially for so-called traditional companies, which were not born in digital culture. Built on an old model, they must initiate and succeed in their transformation to remain competitive. This paper aims to analyze the opportunities brought by digital transformation for Tunisian companies. In our research and on the methodological section, we used an exploratory qualitative approach with Tunisian companies, using a questionnaire. The results of this investigation have shown that the great opportunities and challenges facing Tunisian companies are human capital in the first place, funding and above all methodological support. And the government must be the first to assist and support the digitization process.
