Published: June 2021

Background: The coronavirus disease-2019 (COVID-19) outbreak and a 3-month lockdown of Wuhan may have had a long-term impact on the mental health of frontline healthcare workers (HWs). However, there is still a lack of comparative studies on the mental health of front-line HWs in the initial phase of the lockdown and 1 month after the lifting of the lockdown.

Methods: We recruited 1717 HWs during the initial phase of the lockdown and 2214 HWs 1 month after the lifting of the lockdown, and their baseline characteristics and psychiatric health in these two phases were compared. Furthermore, Pearson's Chi-square test and multivariate logistic regression analysis were used to determine the possible risk factors associated with depressive symptoms in the front-line HWs.

Results: Compared with the initial phase of the lockdown, the proportion of HWs with anxiety symptoms and stress decreased, while the proportion of HWs with depressive symptoms increased a month after the lifting of the lockdown. Male sex, exercise habit, comorbidities, and having family members or relatives with suspected or confirmed COVID-19 infection were significantly related to the increased incidence of depressive symptoms during the initial phase of the lockdown. Comorbidities, negative effect of media coverage, working >4 days a week, lower annual household income, and deteriorating relationships with family members were associated with depressive symptoms a month after the lifting of the lockdown.

Conclusion: The increased proportion of HWs with depressive symptoms 1 month after the lifting of the lockdown suggested that mental health of front-line HWs should be a top-priority issue, not only during, but also after the pandemic.

Published: June 2021

Background: The present study was designed to investigate the relationship between two malnutrition assessment scales, perioperative nutrition screen (PONS) and Nutritional Risk Screening 2002 (NRS2002), with postoperative complications in elderly patients after noncardiac surgery.

Methods: This was a secondary analysis of a prospective cohort study. Elderly patients (65–90 years) undergoing noncardiac surgery were enrolled in Peking University First Hospital. Malnutrition was screened by PONS and NRS2002 at the day before surgery. Multivariable analysis was employed to analyze the relationship between PONS and NRS2002 and postoperative 30-day complications. Receiver operating characteristic (ROC) curve was generated to evaluate the predictive value of PONS and NRS2002 in predicting postoperative complications.

Results: A total of 915 patients with mean age of 71.6 ± 5.2 years were consecutively enrolled from September 21, 2017, to April 10, 2019. The incidence of malnutrition was 27.3% (250/915) by PONS ≥ 1 and 53.6% (490/915) by NRS2002 ≥ 3. The overall incidence of complications within postoperative 30 days was 45.8% (419/915). After confounders were adjusted, malnutrition by PONS ≥ 1 (OR 2.308, 95% CI 1.676–3.178, P < 0.001), but not NRS2002 ≥ 3 (OR 1.313, 95% CI 0.973–1.771, P = 0.075), was related with an increased risk of postoperative complications. ROC curve analysis showed that the performances of PONS [area under the ROC curve (AUC) 0.595, 95% CI 0.558–0.633] showed very weak improvement in predicting postoperative complications than NRS2002 score (AUC 0.577, 95% CI 0.540–0.614).

Conclusion: The present study found that malnutrition diagnosed by PONS was related with an increased risk of postoperative complications. The performances of PONS and NRS2002 were poor in predicting overall postoperative complications.

A Mirror-Based Active Vision System for Underwater Robots: From the Design to Active Object Tracking Application
Authors: Cortés-Pérez Noel , Torres-Méndez Luz Abril
Published: June 2021

A mirror-based active system capable of changing the view’s direction of a pre-existing fixed camera is presented. The aim of this research work is to extend the perceptual tracking capabilities of an underwater robot without altering its structure. The ability to control the view’s direction allows the robot to explore its entire surroundings without any actual displacement, which can be useful for more effective motion planning and for different navigation strategies, such as object tracking and/or obstacle evasion, which are of great importance for natural preservation in environments as complex and fragile as coral reefs. Active vision systems based on mirrors had been used mainly in terrestrial platforms to capture the motion of fast projectiles using high-speed cameras of considerable size and weight, but they had not been used on underwater platforms. In this sense, our approach incorporates a lightweight design adapted to an underwater robot using affordable and easy-access technology (i.e., 3D printing). Our active system consists of two arranged mirrors, one of which remains static in front of the robot’s camera, while the orientation of the second mirror is controlled by two servomotors. Object tracking is performed by using only the pixels contained on the homography of a defined area in the active mirror. HSV color space is used to reduce lighting change effects. Since color and geometry information of the tracking object are previously known, a window filter is applied over the H-channel for color blobs detection, then, noise is filtered and the object’s centroid is estimated. If the object is lost, a Kalman filter is applied to predict its position. Finally, with this information, an image PD controller computes the servomotor articular values. We have carried out experiments in real environments, testing our active vision system in an object-tracking application where an artificial object is manually displaced on the periphery of the robot and the mirror system is automatically reconfigured to keep such object focused by the camera, having satisfactory results in real time for detecting objects of low complexity and in poor lighting conditions.
The Climate Challenge in Managing Water: Evidence Based on Projections in the Mahanadi River Basin, India
Authors: Kumar M. Dinesh , Bassi Nitin
Published: June 2021

This study analyzes the long-term changes in the rainfall and surface hydrology of the upper and middle sub-basins of Mahanadi, an inter-state river basin in eastern India that experiences climate-induced hydrological extremes, and draws implications for the sustainability of irrigation and drinking water supplies. The likely impacts of rainfall changes on surface flow were also modeled. A Water Evaluation and Planning (WEAP) model was set up (beginning June 2009 and ending May 2050) to analyze the future water balance of the basin for the expected changes in socio-economic conditions. The model was also run for future scenarios that considered different water management interventions, and hydrological consequences of climate variability and change. The model results showed that there would be a water deficit, about 2,182 million cubic meters (MCM) by 2050 (20% of the demand) even under the business-as-usual scenario. The gap is expected to widen to 5,005 MCM (25% of the demand) under a high growth scenario. Further, the water demand management interventions in agriculture would be able to reduce the overall demand for water in the basin to some extent, while it would also reduce the supplies slightly due to a reduction in return flows occurring as a result of irrigation efficiency improvement. The water deficit under this scenario will reduce to about 2,773 MCM in 2050. Under the predicted changes in climate, the water deficit is expected to reduce further (will be 1,684–2,373 MCM in 2050) due to an increase in supplies owing to an increase in the catchment yields resulting from higher rainfall. While there will be a significant amount of outflow from the two sub-basins in all the scenarios in most future years (ranging from 25,286 MCM to 28,697 MCM in 2050), during drought years, the water deficit in the upper basin areas will increase slightly, but with a significant reduction in the outflows to the lower sub-basin areas by 2046–47 (will be about 11,311 MCM). These results indicate that there is a need for building more water storage/diversion infrastructure to detain floodwaters during wet years that can provide buffer storage for the dry years.

Published: June 2021

Objective: The aim of this study is to evaluate the possible value of endolymphatic hydrops (EH) in patients with unilateral idiopathic sudden sensorineural hearing loss (UISSNHL) with four types according to audiometry.

Methods: Seventy-two patients (40 men and 32 women; age range, 28–78 years; mean age: 50.0 ± 12.9 years) with UISSNHL were admitted retrospectively into this study. Based on the pure tone audiometry before treatment, the hearing loss of all these patients were categorized into four types: low-frequency group (LF-G), high-frequency group (HF-G), flat group (F-G), and total deafness group (TD-G). The average time from symptom onset to the first examination was 6.9 ± 4.4 days (1–20 days). 3D-FLAIR MRI was performed 24 h after intratympanic injection of gadolinium (Gd) within 1 week after the UISSNHL onset. The incidence of EH in the affected ears based on four types of hearing loss were analyzed using the Chi-square test, and the possible relationship with vertigo and prognosis were also assessed.

Results: Eleven of 21 patients (52.4%) in LF-G had the highest EH-positive rate, followed by 18.2% in HF-G, 11.8% in F-G, and 17.4% in TD-G. The significant difference was found in the four groups (P = 0.018). The EH rate of LF-G was statistically significantly higher than that of F-G and TD-G (P = 0.009, P =0.014), respectively. After being valued by the volume-referencing grading system (VR scores), the EH level was represented by the sum scores of EH. In LF-G, no statistically significant difference was found in the prognosis of ISSNHL patients between with the EH group and the no EH group (P = 0.586). The symptom “vertigo” did not correlate with EH and prognosis.

Conclusions: EH was observed in UISSNHL patients by 3D-FLAIR MRI. EH may be responsible for the pathology of LF-G but not related to prognosis. It might be meaningless to assess EH in other hearing loss types, which might be more related to the blood-labyrinth dysfunction.

Published: June 2021

Piglets with low birth weight (LBW) usually have reduced muscle mass and increased lipid deposition compared with their normal-birth-weight (NBW) littermates. Supplementation of piglets with amino acids during the first days of life may improve muscle growth and simultaneously alter the intramuscular lipid deposition. The aim of the current study was to investigate the influence of glutamine (Gln) supplementation during the early suckling period on lipid deposition in the longissimus muscle (MLD) and the role of different perilipin (PLIN) family members in this process. Four groups were generated consisting of 72 male LBW piglets and 72 NBW littermates. Piglets were supplemented with either 1 g Gln/kg body weight or an isonitrogenous amount of alanine (Ala) between days post natum (dpn) 1 and 12. Twelve piglets per group were slaughtered at 5, 12, and 26 dpn, and muscle tissue was collected. Perilipins were localized by immunohistochemistry in muscle sections. The mRNA and protein abundances of PLIN family members and related lipases were quantified by quantitative RT-PCR (qPCR) and western blots, respectively. While PLIN1 was localized around lipid droplets in mature and developing adipocytes, PLIN2 was localized at intramyocellular lipid droplets, PLIN3 and 4 at cell membranes of muscle fibers and adipocytes, and PLIN5 in the cytoplasm of undefined cells. The western blot results indicated higher protein abundances of PLIN2, 3, 4, and 5 in LBW piglets (p < 0.05) at 5 dpn compared with their NBW littermates independent of supplementation, while not directly reflecting the mRNA expression levels. The mRNA abundance of PLIN2 was lower while PLIN4 was higher in piglets at 26 dpn in comparison with piglets at 5 dpn (p < 0.01). Relative mRNA expression of LPL and CGI-58 was lowest in piglets at 5 dpn (p < 0.001). However, ATGL mRNA was not influenced by birth weight or supplementation, but the Spearman correlation coefficient analysis revealed close correlations with PLIN2, 4, and 5 mRNA at 5 and 26 dpn (r > 0.5, p < 0.001). The results indicated the importance of birth weight and age for intramuscular lipid deposition and different roles of PLIN family members in this process, but no clear modulating effect of Gln supplementation.

Direct observation of the lithiation and de-lithiation in lithium batteries on the component and microstructural scale is still difficult. This work presents recent advances in MeV ion-beam analysis, enabling quantitative contact-free analysis of the spatially-resolved lithium content and state-of-charge (SoC) in all-solid-state lithium batteries via 3 MeV proton-based characteristic x-ray and gamma-ray emission analysis. The analysis is demonstrated on cross-sections of ceramic and polymer all-solid-state cells with LLZO and MEEP/LIBOB solid electrolytes. Different SoC are measured ex-situ and one polymer-based operando cell is charged at 333 K during analysis. The data unambiguously show the migration of lithium upon charging. Quantitative lithium concentrations are obtained by taking the physical and material aspects of the mixed cathodes into account. This quantitative lithium determination as a function of SoC gives insight into irreversible degradation phenomena of all-solid-state batteries during the first cycles and locations of immobile lithium. The determined SoC matches the electrochemical characterization within uncertainties. The presented analysis method thus opens up a completely new access to the state-of-charge of battery cells not depending on electrochemical measurements. Automated beam scanning and data-analysis algorithms enable a 2D quantitative Li and SoC mapping on the µm-scale, not accessible with other methods.

Published: June 2021

It is widely recognized that body dissatisfaction is an important public health concern. In the past, being a fashion model was almost synonymous with anorexia/bulimia, and even today, there are cases of eating disorders in young women whose ambition is to become a top model. Moreover, stress can play a substantial role within ill health via related behaviors such as smoking, substance abuse, and inappropriate eating. In our study, we examined 112 aspiring fashion models aged between 15 and 24 years (M = 19.5, SD = 2.08) from 32 different countries of the world during an international contest, and 100 students (control group), aged between 16 and 22 years (M = 18.6, SD = 1.39). The purpose of this cross-sectional study was to examine whether stress mediated the relationship between body dissatisfaction and eating disorders. The study included the administration of stress and self-efficacy and the locus of control dimensions, body (image) dissatisfaction, and eating attitude disorder. Results indicated higher scores on body dissatisfaction, stress level, and eating attitudes disorder among the group of fashion models compared to the control. Mediational analyses showed that body dissatisfaction was partially mediated by stress level on eating disorders. Especially in the aspiring fashion models, there are often many possibilities that competitive stress causes candidates to exacerbate attempts to maintain their body weight below normal weight/height parameters. These results indicated that appropriate intervention for the management of stress level could possibly defend against the negative impact of body dissatisfaction on eating disorder symptoms. The presence of skilled health workers in the field of nutrition and psychology can be extremely important in the field of fashion to maintain an adequate quality of life.

Published: June 2021

(1) Background: The effects of exercise-based cardiac rehabilitation (CR) on left ventricular function in patients with acute myocardial infarction (AMI) after percutaneous coronary intervention (PCI) are important but poorly understood. (2) Purpose: To evaluate the effects of an exercise-based CR program (exercise training alone or combined with psychosocial or educational interventions) compared with usual care on left ventricular function in patients with AMI receiving PCI. (3) Data sources, study selection and data extraction: We searched PubMed, WEB OF SCIENCE, EMBASE, EBSCO, PsycINFO, LILACS and Cochrane Central Register of Controlled Trials databases (CENTRAL) up to 12th June 2021. Article selected were randomized controlled trials and published as a full-text article. Meta-analysis was conducted with the use of the software Review manager 5.4. (4) Data synthesis: Eight trials were included in the meta-analysis, of which three trials were rated as high risk of bias. A significant improvement was seen in the exercise-based CR group compared with the control group regarding left ventricular ejection fraction (LVEF) (std. mean difference = 1.33; 95% CI:0.43 to 2.23; p = 0.004), left ventricular end-diastolic dimension (LVEDD) (std. mean difference = −3.05; 95% CI: −6.00 to −0.09; p = 0.04) and left ventricular end-systolic volume (LVESV) (std. mean difference = −0.40; 95% CI: −0.80 to −0.01; p = 0.04). Although exercise-based CR had no statistical effect in decreasing left ventricular end-systolic dimension (LVESD) and left ventricular end-diastolic volume (LVEDV), it showed a favorable trend in relation to both. (5) Conclusions: Exercise-based CR has beneficial effects on LV function and remodeling in AMI patients treated by PCI.
Revisiting Giancarlo De Carlo’s Participatory Design Approach: From the Representation of Designers to the Representation of Users
Authors: Charitonidou Marianna
Published: June 2021

The article examines the principles of Giancarlo De Carlo’s design approach. It pays special attention to his critique of the modernist functionalist logic, which was based on a simplified understanding of users. De Carlo′s participatory design approach was related to his intention to replace of the linear design process characterising the modernist approaches with a non-hierarchical model. Such a non-hierarchical model was applied to the design of the Nuovo Villaggio Matteotti in Terni among other projects. A characteristic of the design approach applied in the case of the Nuovo Villaggio Matteotti is the attention paid to the role of inhabitants during the different phases of the design process. The article explores how De Carlo’s “participatory design” criticised the functionalist approaches of pre-war modernist architects. It analyses De Carlo’s theory and describes how it was made manifest in his architectural practice—particularly in the design for the Nuovo Villaggio Matteotti and the master plan for Urbino—in his teaching and exhibition activities, and in the manner his buildings were photographs and represented through drawings and sketches. The work of Giancarlo De Carlo and, especially, his design methods in the case of the Nuovo Villaggio Matteotti can help us reveal the myths of participatory design approaches within the framework of their endeavour to replace the representation of designers by a representation of users. The article relates the potentials and limits of De Carlo’s participatory design approach to more contemporary concepts such as “negotiated planning”, “co-production”, and “crossbenching”. The article also intends to explore whether there is consistency between De Carlo’s theory of participation and its application.
Novel Applications of NSAIDs: Insight and Future Perspectives in Cardiovascular, Neurodegenerative, Diabetes and Cancer Disease Therapy
Authors: Kaduševičius Edmundas
Published: June 2021

Once it became clear that inflammation takes place in the modulation of different degenerative disease including neurodegenerative, cardiovascular, diabetes and cancer the researchers has started intensive programs evaluating potential role of non-steroidal anti-inflammatory drugs (NSAIDs) in the prevention or therapy of these diseases. This review discusses the novel mechanism of action of NSAIDs and its potential use in the pharmacotherapy of neurodegenerative, cardiovascular, diabetes and cancer diseases. Many different molecular and cellular factors which are not yet fully understood play an important role in the pathogenesis of inflammation, axonal damage, demyelination, atherosclerosis, carcinogenesis thus further NSAID studies for a new potential indications based on precise pharmacotherapy model are warranted since NSAIDs are a heterogeneous group of medicines with relative different pharmacokinetics and pharmacodynamics profiles. Hopefully the new data from studies will fill in the gap between experimental and clinical results and translate our knowledge into successful disease therapy.
Simulation and Theory of Classical Spin Hopping on a Lattice
Authors: Gerst Richard , Becerra Silva Rodrigo , Harmon Nicholas J.
Published: June 2021

The behavior of spin for incoherently hopping carriers is critical to understand in a variety of systems such as organic semiconductors, amorphous semiconductors, and muon-implanted materials. This work specifically examined the spin relaxation of hopping spin/charge carriers through a cubic lattice in the presence of varying degrees of energy disorder when the carrier spin is treated classically and random spin rotations are suffered during the hopping process (to mimic spin–orbit coupling effects) instead of during the wait time period (which would be more appropriate for hyperfine coupling). The problem was studied under a variety of different assumptions regarding the hopping rates and the random local fields. In some cases, analytic solutions for the spin relaxation rate were obtained. In all the models, we found that exponentially distributed energy disorder led to a drastic reduction in spin polarization losses that fell nonexponentially.
Mild Fetal Tricuspid Regurgitation in the First Trimester as a Predictor of Perinatal Outcomes
Authors: Park Ji-Eun , Jo Hyen-Chul , Lee Seon-Mi , Baek Jong-Chul , Cho In-Ae , Lee Soon-Ae
Published: June 2021

Background and Objectives: This study aimed to investigate whether mild fetal tricuspid regurgitation (TR) at 11+ 0 to 13+ 6 weeks of gestation affects perinatal outcomes. Since fetal right ventricular load is associated with placental resistance, we hypothesized that fetal mild TR would be associated with perinatal outcomes as a consequence of abnormal placentation. Materials and Methods: We retrospectively evaluated 435 women with first-trimester scan data. Blood flow across the tricuspid valve was examined in singleton pregnancies between 11+ 0 and 13+ 6 weeks of gestation. Women were categorized according to the presence or absence of fetal mild TR, and the maternal and pregnancy characteristics and perinatal outcomes were compared. Multiple linear and logistic regression analyses were conducted to identify independent predictors of perinatal outcome. Results: In the group with mild TR, there were more cases of borderline amniotic fluid index, including oligohydramnios (p = 0.031), and gestational age- and sex-specific birth weights were lower (p = 0.012). There were no significant differences in other perinatal outcomes, including preeclampsia, gestational hypertension and small for gestational age. Gestational diabetes (adjusted odds ratio (OR) 0.514, 95% confidence interval (CI) 0.312–0.947) and fetal mild TR (adjusted OR 1.602, 95% CI 1.080–2.384) were identified as factors associated with below borderline amniotic fluid index before birth. The factors that affected gestational age and sex-specific birth weight were also gestational diabetes (adjusted beta coefficient 9.673, p = 0.008) and the presence of fetal mild TR (adjusted beta coefficient −6.593, p = 0.007). Conclusions: Mild fetal TR observed in the first trimester is negatively associated with fetal growth and the amniotic fluid index at term but not with other adverse pregnancy or perinatal outcomes due to abnormal placentation.

Published: June 2021

Today, most user services are based on cloud computing, which leverages data center networks (DCNs) to efficiently route its communications. These networks process high volumes of traffic and require exhaustive failure management. Furthermore, expanding these networks is usually costly due to their constraint designs. In this article, we present enhanced Torii (eTorii), an automatic, scalable, reliable and flexible multipath routing protocol that aims to accomplish the demanding requirements of DCNs. We prove that eTorii is, by definition, applicable to a wide range of DCNs or any other type of hierarchical network and able to route with minimum forwarding table size and capable of rerouting around failed links on-the-fly with almost zero cost. A proof of concept of the eTorii protocol has been implemented using the Ryu SDN controller and the Mininet framework. Its evaluation shows that eTorii balances the load and preserves high-bandwidth utilization. Thus, it optimizes the use of DCN resources in comparison to other approaches, such as Equal-Cost Multi-Path (ECMP).
Potential and Limitations of Feedback-Supported Gait Retraining in Users of Lower Limb Prostheses
Authors: Rayl Kaitlyn , Fiedler Goeran
Published: June 2021

The outcomes of prosthetic rehabilitation after lower limb loss are, in large part, affected by the effectiveness of the provided gait retraining. The noted prevalence of adverse long-term effects, such as further joint and muscle degeneration, suggests that traditional rehabilitation programs have limitations. Recent advances in technology and in the understanding of motor learning promise the potential for better gait retraining interventions. This article reviews current literature on systems and methodologies of improving gait parameters in those with lower limb prostheses via exercise programs and various biofeedback systems. A total of 13 articles were included in the qualitative analysis. Findings indicate that many of the investigated systems are able to effectively analyze and change gait in the target population, but there remain considerable gaps in the knowledge. It has been noted that feedback modalities and dosage must be customized based on patient characteristics and rehabilitation goals, yet there is currently not enough published evidence to inform such customization.
Functions of nurses through the eyes of patients treated in in-patient departments
Authors: Burlova Natalia
Published: June 2021

The purpose of the study was to examine the adequacy of the provided nursing care to the patient's needs. Results. It was found that, according to patients, the professional functions of a nurse to a greater extent consist in assisting the doctor with the condition of observing the norms of ethics and deontology. A nurse as a subject of the treatment process with the ability to realize competence in teaching self-care and nursing skills, determining the patient's need for nursing manipulations, and taking measures to maintain and promote health is defined as “significant” by only one fourth of the patients participating in the study. The differences in the patients' expectations were identified depending on the profile of the department in which they were being treated, their educational level, social status, and the degree of self-care. Conclusion. It is necessary to further study the opinions of patients about the professional functions of a nurse and the organization of measures to develop the professional activities of a nurse related to the prevention and instructing of patients.
Acceso a las tecnologías digitales para mujeres indígenas rurales. Barreras, catalizadores y sueños
Authors: Hurtado Merlyn Johanna
Published: June 2021

La transformación digital puede beneficiar a un sector de la población y, al mismo tiempo, acentuar las desigualdades de otro. Esta investigación tiene el objetivo de conocer el acceso que tienen las mujeres indígenas a las tecnologías digitales en zonas rurales, reconocer las barreras, catalizadores y sueños, y crear colectivamente las propuestas para eliminar la brecha digital de género en sus comunidades. Las comunidades indígenas participantes son el pueblo nasa (Colombia) y el pueblo ch’orti’ (Guatemala). La metodología combina diferentes herramientas, como las herramientas de investigaciones de género en acceso a internet y uso, Facebook Ads, diagnósticos participativos, Design Thinking y análisis cualitativo. Los resultados encontrados son: el acceso a las tecnologías digitales es precario, no empodera y es inseguro. Las violencias, la asequibilidad y las normas sociales son las principales barreras para el acceso a las tecnologías digitales, y la violencia sexual es la mayor barrera para las niñas indígenas. Los sueños de las mujeres indígenas respecto a las tecnologías digitales son tecnologías para fortalecer el sentir, vivir y pensar como pueblos originarios. Este trabajo presenta estrategias para eliminar la brecha de género, que son relevantes para la cooperación internacional y los actores locales. Se concluye que el ODS 5 (meta 5b) debería incluir la implementación de soluciones tecnológicas que permitan el empoderamiento, y la transformación digital en la ruralidad requiere una agenda conjunta entre los gobiernos, la cooperación internacional y las organizaciones de mujeres indígenas.

Este artigo apresenta resultados de pesquisa que investigou impactos econômicos, sociais e culturais na vida de moradoras/es remanescentes atingidas/os pela intervenção urbanística Orla, que compõe o Projeto Portal da Amazônia em Belém do Pará. A pesquisa foi orientada pelo método do materialismo histórico e dialético e contou com levantamento bibliográfico, documental e de campo. Foram entrevistados/as 39 moradores/as não removidos/as pelo referido Projeto. Durante a pesquisa, pôde-se perceber a memória dos/as moradores/as como forma de resistência às lógicas do projeto, tensionando os discursos oficiais de resgate do contato com o rio e de democratização da orla. Verificou-se que a implementação do Projeto Orla reforça a segregação socioespacial, agrava as condições de moradia e a insegurança da posse. A pesquisa revelou, ainda, como o lugar da memória, do vivido e do valor de uso contrapõe-se ao lugar da intervenção, do valor de troca e da cidade mercantilizada.

Published: June 2021

O artigo problematiza os conceitos de classes e grupos subalternos em Antonio Gramsci a partir da obra carcerária e, particularmente, do Quaderno 25. Objetiva propor uma metodologia de pesquisa para estes conceitos, haja vista o caráter dos Quaderni del Carcere, isto é, uma obra não sistematizada para a publicação. Nesse sentido, partindo de uma pesquisa bibliográfica na edição crítica italiana dos Quaderni, organizada por Valentino Gerratana, evidencia-se a fundamentação teórica do Quaderno 25, na medida em que nele Gramsci apresenta as classes e grupos subalternos, bem como sua história desagregada e episódica, como submetidos a iniciativa da classe dominante. Assim, o problema de como “pôr” fim a subalternidade está atravessada pelo estudo destes conceitos, dada a dedicação de Gramsci em investigar as formas de superá-la, rompendo com a subalternidade econômica, mas, sobretudo, cultural que a estrutura.
DRUCKER-PRAGER MODELS FOR DYNAMIC ANALYSIS OF GRANULAR METAMATERIALS IN EARTHQUAKE ENGINEERING

Published: June 2021

Problem of developing methods for protecting buildings and structures from the vibrations transmitted to them from the soil under the action of seismic effects is extremely important to date. One of these modern methods is seismic pads. The purpose of this work was to study the effectiveness of adding a pad of granu-lar metamaterials under the foundation of the building to decrease influence of seismic shear waves. The Finite Element Analysis of Mohr-Coulomb models was used to achieve this goal. The FE model consists of a ten-story superstructure rested on the slab foundation, under which there is a layer of granular metamateri-als. The values of five variables that affect the mechanical properties of these metamaterials were analyzed (density – cohesion – internal friction angle – Young's modulus – Poisson's ratio) for two different pad thicknesses. The dynamic analysis performed using the software package Abaqus/CAE showed the effec-tiveness of the granular metamaterials in their ability to significantly reduce magnitudes of displacements, velocities and accelerations in the building compared to the same values in the absence of these metamateri-als. The analysis also revealed that among the studied variables, the cohesion is the parameter most influenc-ing the effectiveness of metamaterials in their ability to dissipate seismic waves, while no significant effect was observed for the other parameters

Sensors capable of monitoring dynamic mechanics of tendons throughout a body in real time could bring systematic information about a human body’s physical condition, which is beneficial for avoiding muscle injury, checking hereditary muscle atrophy, and so on. However, the development of such sensors has been hindered by the requirement of superior portability, high resolution, and superb conformability. Here, we present a wearable and stretchable bioelectronic patch for detecting tendon activities. It is made up of a piezoelectric material, systematically optimized from architectures and mechanics, and exhibits a high resolution of

. Additionally, a tendon real-time monitoring and healthcare system is established by integrating the patch with a micro controller unit (MCU), which is able to process collected data and deliver feedback for exercise evaluation. Specifically, through the patch on the ankle, we measured the maximum force on the Achilles tendon during jumping which is about 16312 N, which is much higher than that during normal walking (3208 N) and running (5909 N). This work not only provides a strategy for facile monitoring of the variation of the tendon throughout the body but also throws light on the profound comprehension of human activities.
Folk Legend Malai Mahadheshwara – A Cultural Study
Authors: T.M Geethanjali
Published: June 2021

Malai Mahadeshwara is south Karnataka’s most loved folk legend. It was during the Veerashaiva revolution of 12th century-which sought to establish ‘truth’ ‘dharma’ ‘equality’ in the society, created the circumstances to make a legend like Mahadeshwara who took his rightful place as the people’s leader. He rose to the mantle through his own will and hard work. The critical events of his life have been documented as the folk epic “Malai Mahadeshwara’ passed on as folklore to every generation. This article is also derived from this folk epic. My aim is to educate the modern public about how casteism has propagated and affected our society throughout time and how this has led to revolutions creating many heroes whom to this day are worshiped. People still tell their stories, songs and follow customs, ideals of that era of heroes who broke the shackles of oppression and paved a way for liberation. This enabled people to live a life of dignity, equality in our society, equal opportunities to everyone. Because of the work of these legends, we are able to live today in peace, where everyone has an opportunity to rise up, where people have their own individual identity and are treated with respect. Today any person regardless of caste/religion/gender can rise to the highest rank in society or in organization, can set their own standards for life and make independent decisions. Through this article I want to highlight the contribution of one- Mahadeshwara who became a messiah of common people.

Annelik bekçiliği kavramı, babalığı etkileyen faktörler arasında çok önemli bir yere sahiptir. Alanda nispeten yeni olan annelik bekçiliği kavramı, ülkemizde çok daha yeni bir kavramdır ve halen bu konuda pek çok eksiklikler bulunmaktadır. Bu çalışma ile Fagan ve Barnett’in (2003) ortaya koyduğu Annelik Bekçiliği Ölçeği’nin (ABÖ), okul öncesi dönemde (3-6 yaş aralığı) ve ilkokul döneminde çocuğu olan (7-11 yaş aralığı) hem anneler hem de babalar için ayrı ayrı Türkçe’ye uyarlamasını gerçekleştirmek hedeflenmiştir. Çalışmanın katılımcıları 3-6 yaşında okul öncesi kuruma giden ve 7-11 yaşında ilkokula giden çocuğu olan, evli annelerden ve babalardan oluşmaktadır (okul öncesi için 156 anne ve baba, ilkokul dönemi için 214 anne ve 202 baba). Okul öncesi dönemde çocuğu olan annelerin yaş ortalaması 34.05 (SS=5.22) ve babaların yaş ortalaması 37.17’dir (SS=5.95). Çalışmanın katılımcılarını oluşturan ilkokul döneminde çocuğu olan annelerin yaş ortalaması 34.89 (SS=5.03) ve babaların yaş ortalaması 38.85’tir (SS=5.11). Gerçekleştirilen doğrulayıcı faktör analizi ve güvenirlik analizleri sonucunda, Okul Öncesi Dönem Annelik Bekçiliği Ölçeği-Anne Formu ile Okul Öncesi Dönem Annelik Bekçiliği Ölçeği-Baba Formu’nun ve İlkokul Dönemi Annelik Bekçiliği Ölçeği-Anne Formu ile İlkokul Dönemi Annelik Bekçiliği Ölçeği-Baba Formu’nun istatistiksel açıdan geçerli ve güvenilir olduğu tespit edilmiştir. Ayrıca hem okul öncesi hem de ilkokul dönemi için anne ve baba formları arasında olumlu yönde anlamlı ilişki olduğu görülmüştür. Ölçeklere yönelik betimsel istatistikler de bulgular kısmında sunulmuştur. Uyarlanan ölçeklerle ilgili bulgular literatür çerçevesinde tartışılmıştır.
