Quantitative methods in the field of economic sciences
Authors: Borowska Maria 
Published: June 2020

The usage of quantitative tools for creating the mathematical models of functioning different economic facilities abounds the opportunity for better understanding and acquaintance of the surrounding reality. A lot of thinkers identify even universality of the particular branch of knowledge with the extent of its ‘mathematization’. Applying mathematical methods so called quantitative provide great and not to overestimate services not only in the science research of technique, physics, astronomy, biology and medicine, but also – within the qualitative methods- in the field of social science in the sphere of the control of the quality of production or in the process of service management or decision making. Complex nature of the social and economic phenomena requires making the usage of the most modern means and the ubiquitous computerization significantly confirms the usefulness of these methods. Progressing ‘mathematization’ and computerization of the science forces creating and applying quantitative (mathematical) models including economic science. The model of operating of studied system was considered in two variants. I. when the process of the product delivery to the store represents inclusively the subsystem of production and the subsystem of the transportation – it could be then said that the level of filling the store up is controlled by the aggregated process of the delivery of the product.
when the process of the product delivery to the store takes into account explicate both the production process and also the operating of transportation subsystem, so it is then the structural process of the product delivery. Both in the aggregated and structural version, the analyses of the functioning of the system was made in three variants of the store filling: intermediate state of the store filling; zero state of the store filling that is lower barrier; the state of full storage of the store, that is the upper barrier. The result of my analyses are two proprietary probabilistic models of system operation which are presented through the system of differential equations both in the aggregated and structural variant. Probabilistic models of functioning of the system in both variants presented throughout the probabilistic model also enable determining sizing prognosis which are characteristic for the functioning of this system. These prognoses are transferred to the unit of the management system and they provide the premises to the streamline of its functioning.
These tools create the basics of theoretical and methodological constructed computer programmes of the informative systems of decision-making support.

Authors: Georgiev Pencho G. , Sapunarova Katya G. , Goranova-Marinova Veselina S. , Goranov Stefan E. 
Published: June 2020

Background: Management of beta-thalassemia major (TM) requires life-long hemotransfusions leading to iron overload. Iron elimination is enhanced by the use of modern chelators.&nbsp;
Aim: To assess the effect of modern chelation therapy by dynamics of serum ferritin concentration and liver MRI T2*.
Patients and methods: Forty-six patients with TM (male to female ratio =1:1, mean age 33.2&plusmn;10.9 years) were prospectively studied between 2011 and 2014. Twenty-one patients (45.7%) were treated with deferasirox, 17 (37%) &ndash; with deferiprone, and 8 (17.3%) &ndash; with deferiprone in combination with deferoxamine. Ferritin was measured by ELISA. MRI T2* was assessed by Siemens Magnetom Avanto 1.5T. The patients were allocated into 3 groups based on their initial ferritin level and liver MRI T2*. Statistical analysis was performed using SPSS v. 18 for Windows. Data were analysed by descriptive analysis, analysis of variance and correlative analysis, means were compared using t-test and one-way ANOVA.
Results: In 2011, 9 (19.5%) patients had normal liver MRI T2*; in 2014 they were 17 (37%). The patients with mild grade liver siderosis were 12 (26%) in 2011, and in 2014 they were 14 (30.4%). In 2011, the patients with moderate liver siderosis were 14 (30.4%), and in 2014 &ndash; 12 (26.0%). Eleven patients (23.9%) had severe liver siderosis in 2011 and only two patients (4.0%) were diagnosed with the condition in 2014.
Conclusion: A reduction of iron overload was found in all studied groups. This positive effect is attributed to the use of modern chelators and the ease of access to accurate monitoring.
Does the Bulgarian Health Care System Need a Health Ombudsman?
Authors: Dzhafer Nigyar , Vodenicharov Tzekomir , Papathanasiou Janis 
Published: June 2020

Background: The Office of the Ombudsman of the Republic of Bulgaria (ORB) is an independent constitutional body elected by Bul&shy;garian Parliament in 2005. It serves to protect the rights of all citizens, including the rights of patients, children, people with disabilities, minorities, foreigners, etc. Bulgarian healthcare users complain when they feel that the healthcare system (HCS) has failed their needs or they have been recipients of an inappropriate treatment.
Aim: The aim of the present study was to analyze the structure and dynamics of all complaints from Bulgarian healthcare users referred to the ORB over a 13-year period (2005 &ndash; 2018).
Materials and methods: Retrospective documental research was used in the present study. The data included the complaints ob&shy;tained from the official annual reports of the ORB that are available online. Bibliographic and documental searches were also used as sources. The complaints were analyzed by their annual distribution and classified by problem areas in the HCS.
Results: Between 2005 and 2018, there were a total of 3288 complaints filed to ORB against HCS. In 2015, 368 complaints were re&shy;ceived by ORB from Bulgarian healthcare users and from various patient organizations concerning problems in the HCS. The filed complaints to ORB increased by 82% in 2016 (n=421). In 2017, the overall number of ORB-referred complaints amounted to 494, and in 2018 their number was as high as 607, which represents an increase by 23% compared to the number of complaints in 2017.
Conclusion: The great number of complaints referred to ORB about the HCS over the last four years strongly suggests that the institu&shy;tion of the Ombudsman in Bulgaria enjoys high confidence among Bulgarian healthcare users.
Genetic Polymorphisms Implicated in Major Pregnancy Complications: a Review
Authors: Dryllis Georgios , Liakou Panagiota , Politou Marianna 
Published: June 2020

Pregnancy short- or long-term complications may involve the mother&rsquo;s health, the fetus&rsquo;s health, or both. A systematic literature review was performed, including studies up to October 2018 from Medline (PubMed), Science Direct, Web of Science and Google Scholar. The following inclusion criteria were applied: studies published until 2018 concerning the genetic background of pregnancy complications such as high blood pressure, gestational diabetes, preeclampsia, pregnancy loss, endometrial death, placental abruption, premature labor, and intrauterine growth retardation which may render pregnancy a high risk condition.
We identified 164 articles that met the inclusion criteria and reviewed and analyzed them. The results so far are contradictory and the pathogenicity of these pregnancy complications remains unclear. For most of the polymorphisms studied so far, data refer to small studies size but research is on-going.
The identification of genetic polymorphisms with strong correlations with certain pregnancy complications could provide us with useful tools which could be incorporated in diagnostic algorithms that could facilitate early detection and treatment of major pregnancy complications.

Authors: Stoykova Zhivka , Ivanova Liliya , Cvetkova Snejinka , Yordanova Diana 
Published: June 2020

Background: Cytomegalovirus (CMV) is a worldwide spread herpes virus that establishes a latent infection after the primary infection. It becomes a major problem in immunocompromised patients and in cases of primary or reactivated infection during pregnancy. CMV is the most common congenital infection and is the leading infectious cause of sensoneural deafness and cerebral mental retardation.
Aim: &#1058;o raise the attention to the discordance in our knowledge of cCMV infection and the implementation of the knowledge in prac&shy;tice.
Materials and methods: CMV-DNA was extracted from saliva and plasma samples according to the protocol of DNA-Sorb-A, Sacace, Biotechnologies, Italy. Polymerase chain reaction (PCR) was performed using a commercial kit based on the Taq-man principle: Quantitative RT-PCR for CMV-DNA detection (Sacace, Biotechnologies, Italy). The linear range of the CMV Real-TM Quant PCR test is 500-10000000 copies/ml, and the reported sensitivity is 400 copies/ml.
Results: The infant was born with clinical manifestations involving development of hepatosplenomegaly, chorioretinitis, anemia, mi&shy;crocephaly and simultaneous dilatation of the brain ventricles. CMV infection was confirmed using modern PCR studies.
Conclusions: This case highlights the need for specific virological/PCR tests to be performed for all children with the least suspected congenital infection, especially when there is an option of a specific treatment.
Des inégalités déconfinées par le coronavirus
Authors: Damon Julien 
Published: June 2020

Comme indiqué en ouverture de ce forum (p. 43), le sujet de la crise du Covid-19 et de ses impacts n’est pas près d’être épuisé, et il intégrera progressivement le contexte général d’analyse de nombreux champs d’études. Il nous est cependant apparu important, en ce début d’été 2020, d’ouvrir les colonnes de Futuribles à divers experts pour en évoquer, encore « à chaud », différents aspects, d’ordre économique, social, sanitaire, alimentaire, écologique… Ce deuxième article, de Julien Damon, propose un éclairage sur les inégalités renforcées ou révélées par la crise du Covid-19, au sein de la société française, et celles qu’elle pourrait aussi engendrer dans les mois ou années à venir. La hiérarchie des priorités sociales va-t-elle en sortir bouleversée ? S.D.
Télétravail et croissance économique : une opportunité à saisir
Authors: Cette Gilbert 
Published: June 2020

Voici un cinquième article publié dans le cadre de notre forum « Covid-19 : causes, impacts et stratégies », qui vise à ouvrir les colonnes de Futuribles à divers experts pour évoquer, encore « à chaud », différents aspects, d’ordre économique, social, sanitaire, alimentaire, écologique…, de la crise du Covid-19. Gilbert Cette y montre qu’en dépit des difficultés inhérentes à cette crise sanitaire et aux conséquences économiques qui vont s’ensuivre, il existe aussi une opportunité à saisir dans le domaine du travail. En effet, le confinement et la limitation des déplacements ont permis une large extension du télétravail, qui pourrait perdurer par la suite et permettre, à terme, de relancer la productivité économique, qui semblait en phase d’épuisement depuis plusieurs décennies.

La Terreur, ou comment écrire l’histoire
Authors: Martin Jean-Clément 
Published: June 2020

Arrivera-t-on à prendre nos distances avec « La Terreur » ? Trois publications récentes invitent à revenir sur cette notion qui est au cœur de nos mémoires et de notre culture, et à lui faire perdre son mystère. La question est plus importante qu’il n’y paraît, n’étant ni simplement érudite voire anecdotique, ni réservée aux spécialistes de la Révolution française. La Terreur est un terme entré dans l’histoire mondiale, même dans la philosophie de l’histoire, pour comprendre le sens de l’Histoire et qualifier des événements survenus sur toute la planète. L’étude de « la Terreur » est donc un cas d’école exceptionnel qui fait réfléchir sur l’écriture même de l’histoire, à sa naissance.
Évaluation des compétences en littératie chez les enfants français de 4-5 ans
Authors: Écalle Jean , Labat Hélène , Thierry Xavier , Magnan Annie 
Published: June 2020

Introduction : Très tôt, les enfants d’âge préscolaire développent des capacités langagières dont certaines sont fortement prédictives de l’apprentissage de la lecture. But de l’étude : Cette recherche vise à utiliser un outil court pour évaluer les compétences en littératie. Elle a été réalisée auprès d’enfants de 4-5 ans ( n = 14 820) scolarisés dans des écoles maternelles publiques (réseau d’éducation prioritaire [REP] et non-REP) et privées en France. L’évaluation a porté sur trois domaines : la connaissance des lettres, les habiletés phonologiques et le vocabulaire, avec un nombre limité d’items. Résultats : Les enfants scolarisés en REP ont des scores significativement plus faibles que les enfants scolarisés dans des écoles hors REP. Aucune différence significative n’est relevée entre les scores des enfants scolarisés dans les écoles privées et les écoles publiques hors REP. Un impact significatif du sexe et de l’âge est observé – le premier en faveur des filles et le second en faveur des enfants plus âgés –, celui du sexe s’estompant chez les enfants plus âgés. Enfin, nous avons examiné la distribution des performances dans les trois domaines chez les enfants ayant obtenu les scores les plus faibles. Conclusions : L’utilisation d’un outil court de repérage des habiletés en littératie précoce permet d’examiner directement chez de jeunes enfants les compétences liées à l’apprentissage de la lecture. C’est aussi une occasion de définir et de coordonner des actions préventives pour réduire les difficultés d’apprentissage de la lecture.
Slow and Steady: Gradual Drawdown of Private Wetlands Supports Shorebirds During Northbound Migration
Authors: Souza-Cole Ian , Arthur Samantha , Jensen Laura , Sesser Kristin A. , Strum Khara M. 
Published: June 2020

AbstractThe Grasslands Ecological Area is the largest contiguous wetland complex in California's Central Valley and is a stronghold for hundreds of thousands of waterbirds. Primarily managed for waterfowl habitat and forage production, landowners of these privately owned seasonal wetlands in the Grassland Ecological Area typically flood the wetlands in the fall and dewater them the following spring in February and March. These wetlands support large populations of nonbreeding shorebirds and other waterbirds in winter. When the number of migratory shorebirds using the region peaks in mid-April, landowners have already dewatered most wetlands. The mismatch in the timing of available habitat and the habitat needs of migrating shorebirds contributes to the observed deficit of shorebird habitat in the Central Valley in spring. Working with private landowners, we developed and tested a wetland management practice designed to increase the amount of shallow-water habitat available to shorebirds in April by delaying the drawdown and reducing water levels more slowly (gradual drawdown) relative to the traditional management practice. On average, we found that wetlands managed with gradual drawdown provided over twice as much shorebird habitat, contributing up to 26% of the overall shorebird habitat objective for the Central Valley. Wetlands managed with gradual drawdown supported up to 21 times more migratory shorebirds during peak migration and a greater number of shorebird species than traditionally managed wetlands. Our results demonstrate the potential of working with private landowners to implement small changes in wetland management that can have a large impact in meeting regional conservation objectives for migratory shorebirds.
Crono-génesis de la historiografía asturiana alfonsina
Authors: Martin Georges 
Published: June 2020

Muy al contrario de lo que se afirmó antaño y alguno sigue opinando, la producción historiográfica del reinado de Alfonso III no tuvo los “pobres” y “bárbaros” albores de algún esbozo cronístico “seco”, “frío”, “lacónico” y “oscuro” –ni aun “sencillo” ni “sobrio”–. Tampoco se formó progresivamente, completando con retazos informativos alguna crónica de anteriores reinados. Surgió de golpe, por los años 877-881, con una obra amplia, densa, estructurada, razonada, culta e informadísima a la vez que inventiva, y de ambicioso alcance político: la versión “rotense” de la Crónica de Alfonso III. Sobre esta espléndida base, en el fervoroso scriptorium de la iglesia del Salvador, donde clérigos de procedencia astur, goda o mozárabe colaboraban a su manera en la conquista de un territorio otrora cristiano y en la construcción de la infraestructura gubernativa de un reino en pleno desarrollo, nació primero, en 881, un compendio historiográfico que vinculaba a Alfonso III y a los anteriores monarcas asturianos con los emperadores romanos y los reyes godos. En 883, este entró a formar parte de un memorándum o manual de saberes naturales e históricos que integró la monarquía asturiana en las grandes coordenadas físicas, históricas y culturales del ámbito universal e hispánico. Entre tanto, en el mismo año 883, se había forjado una profecía destinada a afianzar y alentar el impulso reconquistador de Alfonso III. Seguidamente, entre 883 y 890, un historiador regio que tenía a mano el conjunto de los textos conservados o producidos en Oviedo procedió a realzar la dignidad formal de la versión primitiva de la Crónica de Alfonso III, a expurgarla de sus contenidos molestos o escandalosos, y a centrarla más decididamente en la exaltación de la dinastía reinante.
La translation du Libro del Tesoro de Brunet Latin au cœur des enjeux culturels et politiques sous Sanche IV
Authors: Robert Sylvie 
Published: June 2020

Rédigé à Paris entre 1260 et 1267 par Brunet Latin, le Libro del Tesoro est une œuvre à caractère encyclopédique qui traite de l’homme, de Dieu, ou de l’histoire des peuples, mais elle ne peut se résumer à une simple compilation. Le prologue annonce que les trois livres qui constituent le Libro del Tesoro suivent les différentes parties de la philosophie, et le deuxième se centre sur l’Éthique à Nicomaque d’Aristote. Cet ouvrage entend dresser le portrait d’un monarque idéal, juste, savant et sage à travers l’exposition des vices et des vertus. Enfin, le Tesoro réaffirme l’importance du lien à Dieu promu par Sanche IV. On peut donc considérer l’œuvre de Latin comme un véritable manuel de comportement royal, rappelant ainsi la volonté du roi Sanche : asseoir une monarchie forte et chrétienne.
Traduire pour convaincre dans Le Libro de buen amor : les connecteurs en question
Authors: Mencé-Caster Corinne 
Published: June 2020

Le présent article entend examiner les rapports entre « traduire » et « convaincre », à la lumière de l’approche pragmatique de la traduction. En se fondant sur la distinction heuristique entre « sens » et « signification », il s’agira d’analyser la manière dont le traducteur-réenonciateur, qu’est souvent le scripteur médiéval, s’y prend pour inscrire dans le texte source les marques de son propre projet d’écriture. Ce faisant, ce traducteur s’essaie à convaincre son lecteur de la pertinence de sa lecture et de la nécessaire actualisation de sa source. La fable du coq et du saphir du Libro de buen amor constituera le corpus de base et sera analysé à partir des connecteurs.
Traduire pour quoi faire ? Arguments justifiant l’utilité de la traduction dans le prologue de l’Ysopete historiado
Authors: Coussemacker Sophie 
Published: June 2020

La communication examine les arguments avancés pour justifier la traduction en langue vernaculaire des fables, dans le prologue de l’Ysopete historiado castillan, présent dans plusieurs éditions (1482 à 1496). Il s’agit en fait d’une reprise du prologue inventé par le traducteur allemand des fables ésopiques, Heinrich Steinhöwel. Pour justifier ces traductions, ce dernier évoque la longue filiation de traductions de fables du grec au latin, puis aux langues vernaculaires. Il y ajoute aussi une justification par le lectorat : les fables ne doivent pas être réservées aux seuls princes lettrés, mais doivent servir à éduquer tout un chacun. Cette justification s’inscrit dans un débat qui anima le milieu humaniste, notamment italien, qui n’était pas en soi hostile aux fables, mais à leurs versions vernaculaires « populaires ».
Importância do uso das tecnologias na sala de aula
Authors: Silva Joana Brito Oliveira , Santos Maria Luzinete Pinto 
Published: June 2020

O uso de tecnologias na escola é entendido como um recurso para auxiliar o professor na integração dos conteúdos curriculares e inovadores para o fortalecimento da aprendizagem. O presente artigo tem como temática “A importância do uso de tecnologias na prática pedagógica do educador” e tem como objetivo geral analisar o uso das tecnologias na contribuição da aprendizagem. Este artigo nos convida a refletir sobre o uso das novas tecnologias no ensino aprendizado dos educandos e ainda repensar o papel do educador frente às inúmeros desafios que lhe é colocada, utilizar de forma criativa e inovadora os recursos tecnológicos como via de desenvolvimento de potenciais e de atividades necessárias para o desenvolvimento e de aprendizagem. Para a realização deste estudo, foram feitos entrevistas com alunos e professores para conhecer as práticas tecnológicas utilizadas em sala. Foi possível identificar que as maiorias dos educadores são favoráveis à mediação do aprendizado através das novas tecnologias, mas afirmam que existem inúmeros fatores que levam os mesmos a não utilizarem. A pesquisa realizada foi à pesquisa bibliográfica com autores que abordam sobre o tema escolhido e pesquisa de campo analisando o trabalho do educador e suas práticas pedagógicas. O uso da informática na educação implica em novas formas de comunicar, de pensar, de ensinar e aprender. O trabalho é fundamentado em uma pesquisa bibliográfica, a fundamentação se apoia em teóricos como Moran (2009), Freire, Fávero. Esses explicam qualitativa, acolhendo-se como método a pesquisa bibliográfica.
