REPRESENTATION OF POTENTIAL EMPLOYEES ABOUT A MEDICAL ORGANIZATION AS AN ATTRACTIVE EMPLOYER
Authors:   Ural State University of Economics, Pesha A. V. , Litun A. V. ,   LLC “European Medical Center UMMC-Health”
Published: April 2021

In the context of the worldwide acute shortage of qualified personnel in healthcare organizations, one of the most relevant tools for attracting talented doctors to work is an employer brand. The authors analyzed the views of potential job seekers of a medical organization about an attractive, “ideal” employer. Basic research methods are a content analysis of scientific works and an online survey. Based on the content analysis of publications of two abstract databases – eLIBRARY and Web of Science, the work presents the dynamics of the authors’ activity over the past five years, the key focus of the work, and the representation of an employer brand in medical organizations. The analysis reveals that among the abundance and against the background of positive trends in the number of works, only four papers on the employer brand deals with the study of the context in health care organizations, which does not allow judging the disclosure of this topic and offers opportunities for further scientific research. The authors identified the main components of the concept of an employer brand followed by the world scientific community – the presence of a positive image; the set of benefits associated with working in a particular company; and a holistic employer image. These elements formed the basis of the survey. One hundred twenty-nine respondents took part in the empirical part of the study. The study results reflect key factors of the attractiveness of a medical organization as an employer – reputation, personnel care, the existence of a strong leader, competitive salary, possibility of development, and human relations. The paper presents the ideal employer characteristics, according to the respondents, stated in the authors’ concept.

Published: April 2021

Para execução de uma obra residencial é necessário primeiramente a etapa de desenvolvimento de projetos, projetando cada disciplina sequencialmente ou paralelamente. A interação de mais de um profissional na elaboração de um projeto é o caminho certo para uma boa elaboração, entretanto, a centralização de dados permite melhor gestão das informações mitigando problemas de incompatibilidade, que refletem na separação sequencial dos projetos, uma vez que compatibilização fornece uma visão holística do processo. O objetivo deste artigo é analisar erros de execução na construção de uma edificação habitacional em estruturas de concreto armado com lajes pré-moldadas de concreto e vedação em alvenaria, devido à incompatibilidade entre projetos. Para o desenvolvimento da pesquisa foi desenvolvido o acompanhamento das fases de construção por meio de visitas técnicas regulares e registro fotográfico. Sendo uma obra de pequeno porte, os projetos foram realizados de maneira independente e sem o estudo prévio das etapas da construção, o que favoreceu as inconformidades neste estudo de caso. Foram verificados erros de execução causados por incompatibilidade entre projetos arquitetônico, estrutural, elétrico e hidráulico que impactaram negativamente durante a execução do projeto. Desta maneira ressalta-se a importância da compatibilidade entre projetos independente do porte da obra.

Published: April 2021

São inúmeros os impactos que os conhecimentos de Arquitetura e Urbanismo podem repercutir em uma sociedade. Desde 1816, quando fora criada a primeira escola no Brasil, até 2020, são ao todo 67 cursos de Arquitetura e Urbanismo ofertados em 59 instituições públicas. Com isso, este artigo tem por objetivo analisar a distribuição no espaço e no tempo desses cursos públicos de Arquitetura e Urbanismo no Brasil. Para tal, foram levantadas as instituições públicas com essa oferta, suas categorias administrativas, total de vagas anual e data de criação. Esses dados foram processados em figuras e tabelas que permitem observar a distribuição de cursos e vagas pelo território brasileiro, a expansão com o plano de expansão e interiorização das Universidades Federais e a criação dos Institutos Federais de Educação, Ciência e Tecnologia e também as assimetrias regionais. Entende-se que continuar projetos de expansão de formação desses bacharéis para áreas mais periféricas seja fundamental, sobretudo pela possibilidade de se planejar sociedades mais equitativas, com maior qualidade de vida e equilíbrio ambiental.

Authors: Paiva Mayanne Vieira de , Freitas Marcus Vinícius Pereira , Soares Carlos Eduardo
Published: April 2021

As patologias existentes nas edificações de concreto armado ocorrem em função de diversas variáveis, uma das principais é a falta de controle tecnológico durante a obra, a partir do qual é possível prever ou detectar “não conformidades”. A falta ou falha nesse controle pode ocasionar problemas nas estruturas, portanto, os ensaios não destrutivos (ENDs) surgiram como métodos para se estimar a resistência do concreto e verificar a necessidade de reparos ou reforços nas estruturas. O Ensaio Esclerométrico é um END que mede a dureza superficial do concreto, fornecendo elementos para a avaliação da qualidade do concreto em estruturas novas ou antigas, auxiliando na identificação e prevenção de danos associados à durabilidade e segurança estrutural. Este trabalho objetiva realizar uma revisão sobre o ensaio de esclerometria e suas particularidades, bem como analisar os principais fatores que influenciam no ensaio. Buscou-se esclarecer questões acerca das vantagens e limitações da esclerometria e promover conhecimentos sobre a realização do ensaio através de uma revisão bibliográfica que apresenta debates entre normas vigentes relativas ao tema e literaturas publicadas sobre alguns fatores específicos, sendo estes: mão de obra, tipos de cimento e carbonatação, além de apresentar ensaios que auxiliam na análise do índice esclerométrico.

Published: April 2021

Background: External skeletal fixator (ESF) has been recommended as biological method to stabilize open fracture as it does not involves the wound site, besides protecting adjacent soft tissue structures. Considering the advantages of ESF, this study was envisaged with an objective to study the outcome of open fractures of radius-ulna and tibia-fibula stabilized with linear ESF in dogs. Methods: This study included 17 dogs suffering from open long bone fractures of radius-ulna and tibia-fibula, divided into three groups; linear ESF type I or II (group I, n=8) and type III (group II, n=3). In group III (n=6), open fractures were initially treated using conservative methods i.e management of open wound till complete healing followed by delayed internal fixation using intramedullary pin or bone plating. Result: Majority of the open fractures of radius-ulna and tibia-fibula were transverse (64.71%), involving distal third diaphysis (47.06%) in heavy weight (54.55%), 1-3 year old (64.71%), non-descript (35.29%), male (88.23%) dogs due to automobile accidents (58.82%). Neutrophilic (81.47±4.45%) leukocytosis (24610±2461.88 per cumm) and elevated levels of alkaline phosphatase and creatine kinase were observed. Staphylococcus spp. was the common isolated bacteria sensitive to Gentamicin, Cefotaxime, Tobramycin, Amikacin and Neomycin. High per cent fractures (83.33%) in group III had acceptable functional outcome as compared to fractures treated with linear ESF (55.55%) in groups I and II. Osteomyelitis due to pin tract infections was the major complication (8/11; 72.7%) recorded in ESF groups (Group I and II) that lead to delayed and/or nonunion. Weight bearing score improved markedly after removal of the ESF frame. In conclusions, immediate fixation of the long bone fracture using linear ESF in the presence of open contaminated / infected wounds leads to unacceptable outcome. Poor animal compliance, pin tract discharge, osteomyelitis, delayed union and nonunion are major complications associated with linear ESF. Conservative management of the open fracture wound using standard treatment for 2-3 weeks till complete wound healing followed by internal fixation with intramedullary pin or bone plate is recommended for open long bone fractures in dogs.

Published: April 2021

Background: Canine transmissible venereal tumour (CTVT) also known as infectious sarcoma, venereal granuloma, transmissible lymphosarcoma or sticker tumour is usually transmitted through coitus and mainly affects the external genitalia of young sexually matured dogs. Surgery, chemotherapy, radiotherapy and immunotherapy are considered as effective treatment protocols. Therefore, depending upon the availability present study was designed to investigate the efficacy of different surgico-chemotherapeutic protocols for treatment of canine transmissible venereal tumour. Methods: The study was conducted during January 2018 to July 2018 at the Teaching Veterinary Clinical Complex (TVCC) and Department of Veterinary Surgery and Radiology, College of Veterinary Science and A.H., Anjora, Durg (C.G.) on 18 canines of various breed, irrespective of age, sex and divided into three groups consisting 6 animals in each group. Group A was treated with surgical excision of tumour only where as Group B and Group C were treated with surgical excision of tumour followed by administration of Doxorubicin (30mg/m2) BSA and Vincristine sulphate (0.025 mg/kg) intravenously alongwith DNS at 7th and 14th post-operative days respectively. Different physiological and haemato-biochemical parameters (Hb, PCV, TLC, TPC, DLC, serum glucose, TSP, SUN, SC, ALT, AST and ALP) were recorded preoperatively, postoperatively and after chemotherapy at 10th, 30th and 60th days intervals. Result: The present investigation showed transient changes in physiological and haemato-biochemical parameters before, post surgery and post chemotherapeutic management and was within normal range. Histopathological examination revealed confluent sheet of tumour cells arranged in large round oval or polyhedral shaped distributed in tight clusters or cords. Group A showed mild to moderated reoccurrence while Group B showed minimum reoccurrence. Group C showed no reoccurrence. Thus, surgery combined with vincristine therapy is most effective for treating dogs suffering with transmissible venereal tumour.
Efficacy of Natural Plants Extract and Ethnomedicinal Dilution on Bruchid (Callosobruchus maculatus) Management in Storage Mungbean [Vigna radiata (L.) Wilczek]
Authors: Ghosh Sanhita , Roy Anindita , Kundagrami Sabyasachi
Published: April 2021

Background: Storage of pulse grain is a severe on-going problem for farmers, traders and also the consumers. Mungbean [Vigna radiata (L.) Wilczek] is one of such vital protein rich pulse crops of Indian origin referred to as poor man’s meat. Bruchids (Callosobruchus maculatus) (Coleoptera: Bruchidae) are the major polyphagous storage pest of mungbean which causes the substantial post-harvest qualitative and quantitative loss, especially in long time storage condition. This loss directly affects the agricultural economy and also the human health. Methods: To find a solution, we first screened a large variety of mungbean genotypes against bruchid attack and narrowed down to six most potential varieties with highest resistance to bruchids. The present study is intended to manage pest control in post-harvest storage condition using easily available natural and eco-friendly treatment materials against the much-used chemical pest control materials. We have instinctively chosen eight treatment materials that are not used before except one in any earlier but similar studies of pest control management on other grains. Apart from direct natural sources of these treatment materials, we have used two ethnomedicinal dilution and evaluated their management efficacy as well. Result: The study highlights a new promising eco-friendly approach for bruchid management either through the ‘Homeo-Bruchid Interaction’ or through the ‘Easily Available Homemade Remedies.’ Our results are based on the crude extracts. In few specific situations, we have tried to give possible molecular level interactions that provide the bruchid resistance. However, further investigation is deemed necessary to properly assess the quality components of treating seed as well as identifying particular properties that are responsible for bruchid resistance and to confirm the level of human safety based on their bioactivity before commercialization.

Authors: Ramamurthy V. , Sangeetha G. , Shyla B.
Published: April 2021

Background: Horizontal expansion of area under pulses at country level has very little possibilities. This necessitates exploring alternate ways to increase the area and production of pulses. Bt cotton is the major cash crop grown in large area in Southern transition zone of Karnataka on red soils. Bt cotton hybrids are sown at wide row spacing hence provide sufficient space for cultivation of short duration pulses like cowpea and horse gram. Methods: On-farm trials were carried out in medium deep red soils of Basavanagiri village of Mysore district, Karnataka during 2014-15 and 2015-16. There were six treatments consists of Bt cotton with farmers practice (T1), Bt cotton with best management practice (T2), sole cowpea (T3), sole horse gram (T4), Bt cotton intercropped with cowpea (T5) and Bt cotton inter cropped with horse gram (T6). On-farm trials were laid out by using RCBD design in five farmer fields, which served as replications. Result: On-farm investigation indicated that there was no much difference between cotton yield sole crop with BMP and inter cropped cotton yield. However, cotton yield was significantly lower in farmers practice over BMP. Intercropping of cowpea and horse gram with Bt cotton resulted in higher cotton equivalent yield, LER and production efficiency over the sole cotton cropping system. This was due to the wider spacing of the cotton and better resource use efficiency in intercropping system.
Genetics of Cercospora Leaf Spot Resistance in Mungbean [Vigna radiata (L.) Wilczek] through Generation Mean Analysis
Authors: Choudhary Priyanka , Chand Ramesh , Singh Anil Kumar
Published: April 2021

Background: Cercospora leaf spot (CLS) is a fungal disease of mungbean [Vigna radiata (L.) Wilczek] caused by Cercospora canescens and now emerged as an important biotic stress. A better understanding of the genetics of CLS resistance will help in formulating efficient breeding procedures in mungbean. Methods: The present investigation focused on genetics of CLS resistance through generation mean analysis (six parameter model) in two intra-specific mungbean crosses namely, Kopergaon × HUM12 and Kopergaon × ML1720. Four quantitative disease resistance components, viz., Area under disease progress curve (AUDPC), Incubation period (IP), Latent period (LP) and degree of sporulation (SP) were studied. Result: A high correlation of AUDPC with latent period (r = –0.68 to –0.79, P less than 0.0001) and SP (r = 0.72 to -0.81, P less than 0.0001) advocated that both are main contributor for CLS disease development. High heterosis along with high heritability in terms of AUDPC ( greater than 0.09) indicated the importance of genetic factor(s) in controlling CLS resistance. Generation mean analysis of both the crosses revealed duplicate epistatic interaction and involvement of two genes for CLS resistance in terms of AUDPC. This study supports oligogenic nature of inheritance, advocating AUDPC along with IP, LP and SP as important disease indicator for selection of CLS resistance in mungbean.

Published: April 2021

En Côte d’Ivoire, plus de la moitié du couvert forestier (57 %) a disparu en un quart de siècle (1990-2015) avec une perte importante de biodiversité. Pour mieux comprendre les dynamiques en cours et appuyer les politiques de réduction de la déforestation, des cartographies fines et régulières des changements d’occupation et d’usage des terres sont nécessaires. Cependant, ces études sont rarement conduites sur de grands territoires ou bien elles sont parfois obsolètes à cause de la rapidité des processus anthropiques sous-jacents. L’objectif de cette étude est d’évaluer les changements d’occupation et d’usage des terres, en particulier les dynamiques de déforestation et de dégradation forestière dans trois régions du Sud-Est de la Côte d’Ivoire, entre 2016 et 2019. La méthodologie est basée sur l’utilisation d’images Sentinel-2 à 10 et 20 m de résolution spatiale sur une zone d’étude de 22 014 km2. Des données d’apprentissage ont d’abord été délimitées en suivant une description de la zone en 16 catégories d’occupation et d’usage des terres. Celles-ci ont ensuite été utilisées avec l’algorithme Random Forests pour produire des cartes d’occupation et d’usage des terres en 2016 et 2019 avec une précision globale respective de 92 % et 87 %. Enfin, ces cartes ont été croisées pour décrire les transitions forestières de la zone étudiée. Les résultats révèlent que l’extension des cultures de rente (cacao-café, hévéa et palmier à huile), des cultures et jachères non différenciées ainsi que des infrastructures (habitations et routes) a conduit à un taux de déforestation de 4,95 % par an sur la période étudiée. Cette étude fournit ainsi une compréhension détaillée et actualisée des changements d’occupation et d’usage des terres, et contribue aux réflexions sur la mise en place d’un système national de surveillance des terres.
Evaluation of different peatland management scenarios to reduce GHG emissions from fires. A case study in tropical peatlands in Ogan Komering Ilir, Indonesia.
Authors: RODRÍGUEZ VÁSQUEZ María José
Published: April 2021

Tropical peatlands play an important role as carbon pools. Over the last decades, deforestation and degradation of Indonesian peatlands have led to a significant amount of carbon loss. Anthropogenic fires damage the ecology, the economy, and the public health of the entire region. This PhD is based on a case study in Ogan Komering Ilir (OKI) district of Indonesia. In OKI, traditional practices discard unwanted biomass with open fires, and often result in peat fires. We considered different scenarios of biomass valorisation to incite changes of practices, and to reduce peatland fires. We assessed the feasibility of converting aboveground biomass into bioenergy or other ligno-cellulosic materials.
We estimated a business as usual (BAU) scenario by evaluating sources of emission of the current land management. We investigated potential mitigation scenarios, including biomass valorisation and peatland restoration, as alternative land management options. We evaluated the impact of these mitigation scenarios on climate change, according to their economic limitations.
The analysis of GHG emissions in the BAU scenario shows that areas affected by fire release 70 ± 30, 140 ± 31 and 160 ± 27 Tonnes CO2-eq/ha/yr for degraded peatland, oil palm plantations and pulpwood plantations, respectively. Areas not affected by fires release 19 ± 12, 85 ± 21 and 108 ± 15 Tonnes CO2-eq/ha/yr, respectively. For the restoration scenario, we found similar GHG emissions of –0.9 Tonnes CO2-eq/ha/yr for the three land uses.
Encouraging the biomass market in the areas where it is profitable for farmers could help reducing fire occurrences, without government investment. We instead suggest focusing government efforts on other methods such as incentive payments, or peatland restoration strategies, in the areas where biomass market is not economically viable. For the region, we find that biomass valorisation can reduce the GHG emissions by 4% to 6% compared to the BAU.
As such, biomass valorisation is a promising alternative to current practices, potentially reducing the negative impact of fires while generating a new income for the population.

La diagnosi di infezione da HIV negli anziani è un argomento poco discusso. Tuttavia, sarebbe importante stabilire l’esatta prevalenza dell’infezione nei pazienti di età superiore ai 70 anni. Presentiamo qui il caso di una donna di 86 anni senza alcun fattore di rischio noto per infezione da HIV in cui, accidentalmente, la diagnosi è stata effettuata di recente. Condividiamo, inoltre, le nostre riflessioni riguardanti le difficoltà legate alla gestione, il follow-up ed il trattamento dei pazienti più anziani.
Co-infezione da SARS-CoV-2 in una coorte di persone con infezione da HIV: un’esperienza monocentrica.
Authors: C Russo , al. et
Published: April 2021

Da febbraio 2020 ad oggi diversi autori hanno studiato e descritto il decorso clinico dei pazienti con infezione da HIV e la concomitante infezione con il nuovo coronavirus SARS-CoV-2. Tra il 24 febbraio e il 15 giugno 2020 quattro pazienti con infezione da HIV e diagnosi certa di infezione da SARS-CoV-2 sono stati registrati nel nostro Ospedale. Di questi quattro pazienti, due avevano un’età maggiore di 65 anni e comorbidità multiple. Uno dei due pazienti over 65 ha avuto una infezione asintomatica da SARS-CoV-2, l’altro è invece deceduto in ospedale dopo ventilazione meccanica non invasiva. Gli altri due pazienti avevano un’età inferiore ai 65 anni ed una anamnesi patologica remota non rilevante. Entrambi i pazienti con età inferiore a 65 anni sono guariti dal COVID-19. Tutti e quattro i pazienti, alla stadiazione per HIV precedente la diagnosi di COVID-19, avevano una conta di linfociti T CD4 > 500/mmc e HIV-RNA non rilevabile. I dati preliminari della nostra osservazione inducono a considerare che il paziente HIV anche in buon compenso immuno-virologico può essere considerato più a rischio di gravità della polmonite da SARS-COV-2 se è anziano e con multiple comorbidità, quindi alla stregua dei pazienti non-HIV con patologia COVID-19.

Authors: Kostiukow Anna , Kaniowska Marta , Samborski Włodzimierz
Published: April 2021

Introduction Physical efficiency determines ability to undertake various every-day activities. The greater it is, the better a person’s quality of life and health becomes. Aim The aim of the study was the characterization of motor skills in primary school students from the 7th and 8th classes, and to compare individuals training volleyball with those who participated only in physical education classes. Material and methods The research material included 76 individuals, 41 of whom were from the training group and 35 from ordinary classes of the 7th and 8th classes of primary school. The method was the Physical Efficiency Index created by Zuchora, by means of which speed, jumping ability, arm strength, abdominal muscle strength, flexibility and stamina were evaluated. In addition, the students’ parents completed the author’s questionnaire about their own and their children’s physical activity and eating habits. Results and conclusion The training group obtained 21 points on average and the group that did not train volleyball – 17. Despite this difference, both classes qualified for an average good mark – in the volleyball classes, over 50% got good or very good marks, whereas in the ordinary classes, more than 50% received good or satisfactory marks. In the individual trials, statistically significant (α ≥ 0.05) differences were found in the jumping ability, arm strength and stamina. Students of sports classes demonstrate better physical efficiency and the biggest differences are visible in the area of stamina. Regular physical activity has a positive impact on the students’ efficiency and fitness. Keywords: primary school pupils, physical activity, physical efficiency, motor skills
Derrames de la inversión extranjera directa y su efecto en las exportaciones: una aplicación empírica en un país emergente
Authors: Mesa Ramón Javier , Villar Cristina , Pla-Barber Jose
Published: April 2021

Este trabajo investiga, por primera vez en el caso colombiano, los efectos indirectos de los derrames de la inversión extranjera directa (IED) sobre las exportaciones de las empresas nacionales. A nivel empírico utilizamos una muestra de conveniencia formada por 32 empresas exportadoras, 14 filiales extranjeras y 18 empresas domésticas, las cuales mantuvieron continuidad en cerca de 60% del valor total de la oferta exportable nacional en el periodo de 2007 a 2016. Mediante el uso de un panel de datos con efectos fijos, demostramos que los efectos positivos de la entrada de IED sobre la exportación de las empresas locales se asocian más con mecanismos de reacción para la protección de sus mercados internacionales a partir del denominado efecto competencia, y no con los procesos de aprendizaje exportador por el conocimiento, la tecnología y la experiencia que poseen las empresas extranjeras.

Published: April 2021

HighlightThe highest composition was Bacillariophyceae class and lowest was Cyanophyceae.Phytoplankton community abundance in waters is tightly related with nutrient content such as phosphate, nitrate, silicate, and other nutrients.Relation between abundance, biomass, and nutrients in Mamberamo river had the same pattern throughout February, May, and August in 2016.High biomass in an area related positively with phytoplankton abundance in its area.AbstractMemberamo River in Papua Province, that is a place of livelihood for the surrounding population, has a high biodiversity. This study aimed to provide information about the condition of the waters in the Mamberamo River by using biological and chemical parameters, namely community and phytoplankton biomass and chlorophyll-a content. The method used in determining the location was purposive random sampling based on differences in microhabitat that conducted in February, March, August, and October 2016. Phytoplankton observations were carried out through the method of sweeping Sediment Rafter (SR), and phytoplankton biomass obtained from chlorophyll-a. The results of this study showed three classes of phytoplankton were found, namely Bacillariophyceae, Chlorophyceae, and Cyanophyceae. The highest class of abundance was found in the river such as Bacillariophycea Chlorophyceae, and Cyanophyceae respectively. The chlorophyll-a concentration of phytoplankton biomass ranged from 2.01-548.73 mg/l and equation obtained from regression analysis between abundance and chlorophyll-a content was y = 1.2206 x – 0.7702 with a coefficient of determination r = 0.68.

HighlightHeavy metals (Cu, Zn, Pb, and Cd) in the seawater, sediment, and soft part of marine mussels were analyzedBioaccumulation Factor (BAF), Estimated Daily Intake and Target Hazard Quotient (THQ) were calculatedHeavy metals in the seawater, sediment and marine mussels were found in varying concentrationsHealth risk assessment indexes showed low values which means insignificant health hazardAbstractMarine mussels are known as one of the biological indicators of heavy metals pollution in the aquatic environment and the sources of protein for human consumption. This study aimed to investigate the concentration of heavy metals (Cu, Zn, Pb, and Cd) in the seawater, sediment, and soft parts of the marine mussels (Perna viridis, Meretrix sp., and Anadara granosa), as well as to evaluate its health risk of consumption from Madura Strait, Indonesia. The seawater, sediment, and marine mussels were obtained from four sites and heavy metal concentrations were analyzed using Atomic Absorption Spectroscopy. In the seawater, heavy metals were in the order of Cu, Pb, Cd, and Zn from the highest to the lowest concentration respectively, while they went down in the order of Zn, Cu, Pb, and Cd in the sediment respectively. Excluding the Pb, higher Cu and Zn concentrations were observed in marine mussels than in seawater and sediments (BAF> 1). Furthermore, it was proven that Cu and Zn were considered as essential metals and required for metabolism, while Pb and Cd were non-essential metals which their biological functions were unknown. The Estimated Daily Intake (EDI) of the marine mussels was lower than the oral reference dose (ORD) and low values of target hazard quotient (THQ < 1) had shown that the consumption of mussels containing heavy metals would not cause significant health risks to humans. The health risk assessment indexes showed low values, which meant insignificant health hazard. However, long-term exposure and the impact of consuming mussels containing heavy metals may require additional investigation

The consensus problem has a crucial role in theoretical and practical aspects of interconnected systems, for instance in smart computing field. This paper is concerned with the observer-based H∞ consensus problem for a class of linear multi-agent systems subject to measurement outliers. In the addressed observer-based H∞ consensus problem, measurement outliers can affect the estimation accuracy and thus affect the consensus performance. To assuage the impact of measurement outliers, a control protocol based on an observer containing a saturation function with variable saturation limits is proposed. The purpose of this paper is to find a solution to the addressed H∞ consensus problem for a class of linear multi-agent systems subject to measurement outliers by designing an observer-based control protocol such that multi-agent systems can fulfill the H∞ consensus performance over a finite horizon. With the aid of Lyapunov theory, the sufficient condition is established to guarantee that the consensus error dynamic system satisfies the H∞ consensus performance. Then, the linear matrix inequality (LMI) approach is used to obtain the desired parameters of the observer-based control protocol. Finally, the effectiveness of the proposed control protocol is verified in a simulation environment. Aim: The purpose of this study is to find a solution to the addressed H∞ consensus problem for a class of linear multi-agent systems subject to measurement outliers. Methods: By choosing a suitable Lyapunov function, the sufficient condition is obtained, which can guarantee the consensus error dynamic system satisfying the given H∞ consensus performance. The LMI approach is employed to design the desired controller. With Matlab LMI toolbox, a numerical example was conducted to demonstrate the effectiveness of the proposed observer-based control protocol in the simulation environment. Results: A satisfactory consensus performance can be guaranteed for multi-agent systems subject to measurement outliers under the proposed observer-based control protocol. The constructed saturation function with variable saturation limits can mitigate the effect of measurement outliers by dynamically regulating saturation limits. Compared with the traditional observer-based control protocol, in this paper, the proposed observer-based control protocol shows robustness against measurement outliers. Conclusion: A solution to the addressed multi-agent consensus problem subject to measurement outliers was found by designing an observer-based consensus controller. The obtained results can be extended to sensor networks, neural networks, and nonlinear multi-agent systems.

Published: April 2021

Background: Micronutrients has roles in strengthening and maintaining immune function, but its supplementation and/or deficiency effects on respiratory tract infections are inconclusive. This review aims to systematically assess the associations between micronutrient supplementation or deficiency, with novel coronavirus incidence and disease severity. Methods: Systematic literature searches conducted in 5 electronic databases identified 751 unique studies, of which 33 studies (5 supplementation studies, 1 supplementation and deficiency study, and 27 deficiency studies) were eventually included in this review. Proportions of incidence and severity outcomes in each group, and adjusted summary statistics with their relevant 95% confidence intervaIs (CI) were extracted. Data from 19 studies were pooled in meta-analysis using the generic inverse variance method. Findings: A total of 360,346 patients across 16 countries, with a mean age between 32 and 87.7 years, were involved across 33 studies. All studies were on COVID-19 infections. In individuals without micronutrient deficiency, there was a significant reduction on odds of COVID-19 incidence (pooled OR: 0.37, 95% CI: 0.18, 0.78), and ICU admissions or severe/critical disease onset (pooled OR: 0.26, 95% CI: 0.08, 0.89). Insignificant protective effects were observed on other outcome measures – mortality, ICU admission, progression to respiratory-related complications, severe/critical disease onset or requiring respiratory support and hospitalization rate. Conclusion: The absence of micronutrient deficiency significantly reduced COVID-19 incidence and clinical deterioration in hospitalized patients. Usage of micronutrients as prophylaxis and complementary supplement in therapeutic management of COVID-19 patients may be a promising and cost-effective approach warranting in-depth investigation.

Published: April 2021

This paper proposes a method for monitoring the structural health of concrete bridges in Iran. In this method, the bridge condition index (BCI) of bridges is determined by the analytical hierarchy process. BCI constitutes eight indices that are scored based on the experts' views, including structural, hydrology and climate, safety, load impact, geotechnical and seismicity, strategic importance, facilities, and traffic and pavement. Experts' views were analyzed by Expert Choice software, and the relative importance (weight) of indices were determined using the analytical hierarchy process (AHP). Then, the gave scores of experts were assigned to indices for various conditions. Bridge inspectors can examine the bridge, determine the scores of indices, and compute BCI. Higher values of BCI ​​indicate better conditions. Therefore, bridges with lower BCI take priority in maintenance activities. Five bridges in Iran, Semnan province, were selected as the case studies, and BCI calculation of these bridges was conducted.

Published: April 2021

In Model-Driven Development (MDD), the models, their generation, and imposing changes on them (model transformation) are used for the development of software. Models provide a framework to start from the imagination and abstraction to create and accomplish the final system. Models create a slow and steady transition from whatness to howness, i.e. from the natural path of the generation of software. For supporting this path, the Logic and Functionality of software must be changeable during its evolution. Here we provide a brief introduction to the concept of Model Driven Development.
