Authors: Gutiérrez Uribe Jorge Eliécer
Published: March 2022

La presente investigación tuvo como propósito la generación de un modelo didáctico para la enseñanza y aprendizaje de las matemáticas con materiales didácticos manipulables en alumnos del ciclo de la educación básica primaria, en las instituciones oficiales del municipio de Piedecuesta, Santander. Para lo cual, se consideró fundamental realizar un análisis sobre las concepciones que poseen los docentes sobre la enseñanza y aprendizaje de las matemáticas y atendiendo a estos resultados, se definieron las categorías que explicaron la práctica desde sus ideas. De la misma manera, se analizaron las actuaciones que en la práctica tenían los docentes sobre la didáctica que implementaban, para hacer la propuesta teórica de un modelo didáctico. Teóricamente, la investigación se fundamentó en las consideraciones de Godino (2011), quien concibe la didáctica de las matemáticas como una ciencia orientada al diseño de procesos. Epistemológicamente, se atendió la relación del sujeto cognoscente y el objeto por conocer, enmarcado desde el paradigma y enfoque epistemológico de la investigación científica cualitativa de carácter fenomenológico. El espacio universo estuvo constituido por los docentes de aula del ciclo de educación básica primaria, de quienes se recogió información mediante la aplicación de una entrevista semiestructurada. Todo ello motivó a la generación de un modelo didáctico para la enseñanza y aprendizaje de las matemáticas con materiales manipulativos, conllevando a la construcción de aportes teóricos para el fortalecimiento de la enseñanza de la matemática a partir de las concepciones docentes y prácticas pedagógicas.

Uno de los desafíos presentes en el contexto educativo es el de mejorar la apropiación del conocimiento en las diferentes temáticas impartidas en el aula, tomando en consideración la complejidad de las mismas y las diversas formas de aprender de los estudiantes actuales. En este sentido la gamificación se constituye como una herramienta fundamental para enriquecer y apropiar de mejor forma los procesos de enseñanza y aprendizaje en el aula, teniendo como ventaja el incremento de la motivación y la inmersión por parte de los estudiantes en las temáticas de los diferentes cursos. En ese mismo orden de ideas, las empresas también requieren la apropiación de conocimiento en ciertas temáticas por parte de sus trabajadores y clientes, por lo que la inclusión de la gamificación puede contribuir a mejorar la competitividad de estas en el mercado de la mano de la innovación. De acuerdo a lo anterior, en este artículo se propone como aporte la construcción de un recurso educativo basado en M-Learning y gamificación para contribuir con la apropiación del proceso de construcción y mantenimiento de los sistemas de producción acuapónica por parte de los trabajadores y clientes de la empresa GREENFISH del departamento del Cauca. El recurso construido fue validado a través de la prueba de conocimiento, la cual permitió evidenciar una mejora representativa en el número de participantes que respondieron de manera correcta a las preguntas en el postest con respecto al pre-test.

Authors: Adibi Mina , Naghavi Nafiseh Sadat , Zohrabi Dina Sadat
Published: March 2022

Using inexpensive sources is a crucial point in the production of valuable compounds such as lactic acid. In the present study, the production of lactic acid by an efficient isolate of S. thermophilus was optimized using whey as a carbon source and yeast extract as a nitrogen source. MRS culture medium with 6.5 % NaCl was used for the isolation of streptococci from industrial yogurt samples and the selected isolate was identified using the 16S rRNA gene sequencing. Evaluation of lactic acid production was done by the Randox method. Lactic acid production by the selected isolate was optimized by response surface methodology (RSM) in MRS broth regarding to different concentrations of whey and yeast extract. The isolate that produced the highest amount (8.9 g.L-1) of lactic acid within 52 h growth in MRS broth was identified as a strain of S. thermophilus by molecular identification. Optimization of concentrations of carbon and nitrogen sources resulted in the induction of lactic acid production by Streptococcus thermophilus up to 24.18 g.L-1 in the presence of 3.5 % of whey and 5 % of yeast extract as external carbon and nitrogen sources in the MRS medium, which was similar to the value predicted by RSM. Yeast extract was found to be more effective on lactic acid production than whey. Optimization of lactic acid production by low-cost substrates whey and yeast extract resulted in high induction of lactic acid production by S. thermophilus compared to some other studies that used other cost-effective substrates and/or bacteria isolated from traditional dairy products.

Authors: Al-Rubaye Ali , Abdulwahid Dhurgham , Ejbary Abbas , Al-Rubaye Laith , Albadran Aymen
Published: March 2022

Background: The recent coronavirus (SARS-CoV-2) pandemic has created a serious public health concern worldwide. Shortly after the successful mapping of the genome sequence of SARS-CoV-2 and the declaration of the pandemic by the World Health Organization (WHO) in early 2020, scientists and pharmaceutical companies raced against time in efforts to develop vaccines. As of the 18th of February 2021, the WHO had approved at least seven different vaccines to be rolled out worldwide. However, despite the seriousness of the pandemic and its rapid spread, Iraqi society still refrains from taking vaccines against the disease. Although there is an increase in vaccination with the availability of coronavirus vaccines in Iraq, the rate remains below the level required to achieve herd immunity in Iraqi society soon.
Objectives: To assess the spread of COVID-19 vaccine related misinformation in the Iraqi community.
Methods: A cross-sectional study based on an internet survey that contained a 14-item questionnaire to assess public knowledge related to the COVID-19 vaccine.
Results: A total of 1066 participants completed the survey questionnaire. The study showed a high level of COVID-19 vaccine–related misinformation in the Iraqi community. Individuals who are unemployed with low education levels and living in rural areas, those who did not take the vaccine, and those who were unwilling to advise others to take the vaccine had significantly increased the level of COVID-19 vaccine–related misinformation. In addition, this study found that the most common sources of information among participants were websites and social media.
Conclusions: COVID-19 vaccine–related misinformation is widely spread. This aspect must be considered in any planned public measure that aims to control the pandemic.
Contrast Enhanced Fluid-Attenuated Inversion Recovery Versus Contrast Enhanced T1-Spin Echo Magnetic Resonance Imaging in the Evaluation of Infectious Meningitis
Authors: Abdul-Ra'aoof Husham , Al-Khalissi Mohammed
Published: March 2022

Background                                                                                                                                        
Infectious meningitis is an infection of the subarachnoid space causing inflammation of the leptomeninges. Early diagnosis is crucial to initiate appropriate therapy, avoid complications, and improve prognosis. Cerebrospinal fluid analysis is important in the diagnosis and is done by performing lumbar puncture with some limitations and complications. MRI plays a role in the diagnosis by depicting abnormal leptomeningeal enhancement.
Aim of the study
To evaluate the efficiency of contrast-enhanced fluid-attenuated inversion recovery compared with contrast-enhanced T1 spin echo in the diagnosis of infectious meningitis.
Patients and Methods
A prospective analytical study of diagnostic tests was conducted. Brain MRI was done using a 3-Tesla system. Gadolinium was used as contrast material. The final diagnosis of meningitis was made based on cerebrospinal fluid analysis. Validity parameters, predictive values, and diagnostic accuracy for both sequences were calculated and compared to each other. Quantitative and qualitative analysis was performed.
Results
Fifty-six patients were involved (31 males and 25 females) in this study, and they ranged from 15 to 68 years in age. Cerebrospinal fluid analysis was positive in 41 patients and negative in 15. Contrast enhanced–fluid attenuated inversion recovery has higher sensitivity, specificity, positive predictive value, negative predictive value, and accuracy compared with contrast enhanced–T1 spin echo. The mean net meningeal enhancement is significantly higher in contrast enhanced–fluid attenuated inversion recovery. Substantial interobserver agreement between the two sequences was observed.
Conclusion
Contrast enhanced–fluid attenuated inversion recovery is superior to contrast enhanced–T1 spin echo in the diagnosis of infectious meningitis.

Authors: Ahmed Sahira , Mohammed Ali
Published: March 2022

Background: Patients undergoing endoscopic sinus surgery may develop complications because of the sinuses’ proximity to the orbit and skull base. Endoscopic sinus surgery is done for patients with chronic rhinosinusitis with polyps (CRSwNP), chronic rhinosinusitis without polyps (CRSsNP) not responding to the medical treatment, and antrochoanal polyps.
Objectives: The present study aims to evaluate the complications of functional endoscopic sinus surgery (FESS) in Mosul city.
Methods: A case series study of 70 patients of different age groups who underwent functional endoscopic sinus surgery (FESS) for chronic rhinosinusitis with polyps (CRSwNP), chronic rhinosinusitis without polyps (CRSsNP), and antrochoanal polyps at Al-Jamhoory Teaching Hospital, Mosul, Iraq, for the period from October 2011 to August 2012.
Results: The age of patients ranged from 11 to 65 years, with a mean of 33.1 years.
Thirty-four patients (48.57%) were male, and 36 patients were female (51.43%). Minor complications were observed in 25.71% of our patients. No major complications occurred.
Conclusion: Although functional endoscopic sinus surgery (FESS) is an effective and minimally invasive technique, intraoperative and postoperative complications can still arise. Fortunately, complications are mostly minor, but patients should be informed about these complications. We recommend further studies on complications of endoscopic sinus surgery with more patients and a longer follow-up period.

Authors: Fiori Simone , Sabino Nicola , Bonci Andrea
Published: March 2022

The present paper reports on the current progress about the laboratory-based assessment of the fluency of attitude maneuvering of a quadcopter. The manuscript illustrates a laboratory-based data-acquisition setup and a mathematical data-processing algorithm to test a novel attitude maneuvering fluency estimation index termed geometric lurch. The geometric lurch index is defined in terms of angular variables’ values as returned by gyroscopic sensors that a quadcopter vehicle is equipped with. The results of several numerical tests, conducted on both synthetic and real-world gyroscopic signals, show that the geometric lurch index is fairly sensitive to the fluency of attitude maneuvering.

Published: March 2022

En este trabajo presentamos un acercamiento a la categoría de institución social apartir de diferentes enfoques. Para ello elegimos por un enfoque metodológico cualitativobasado en entrevistas a integrantes de la justicia penal. Luego pasamos a analizar alcastigo estatal como una compleja institución social, dado que dicho castigo vienerecibiendo múltiples objeciones en las últimas décadas, especialmente por su aparenteineficacia. Los resultados más relevantes que se presentan se vinculan con dos elementosque conforman la dimensión judicial del castigo estatal. El primero está relacionado conlas instituciones que los propios actores judiciales consideran importantes a la hora deanalizar la administración de la sanción del Estado. El segundo elemento se orienta alimpacto concreto que produce la pena según las percepciones que brindan al respecto losoperadores jurídicos. En definitiva, a partir de la articulación de ambos componentesanalizamos con mayor detalle algunos de los criterios judiciales que configuran elproblema social del castigo estatal.

Evaluation of Different Turbulence Models at Low Reynolds Number for the Flow over Symmetric and Cambered Airfoils
Authors: Hassan Tafsirul , Islam Md. Tazul , Rahman Md. Mizanur , Ali Abu Raihan Ibna , Ziyan Asif Al
Published: March 2022

This paper presents an evaluation of five different turbulence models by comparing the numerical data derived from these models using ANSYS Fluent with experimental data at a Reynolds number and a Mach number of 0.05 × 106 and 0.015 respectively based on the centerline chord of the airfoil for the flow over NACA 0012 and NACA 2412 airfoils. Moreover, the aim of the present study is to demonstrate the difference in aerodynamic characteristics of the airfoils in order to find aerodynamically more advantageous airfoil. It is concluded that Spalart-Allmaras model and k-ω SST model are capable of providing the most accurate prediction for lift coefficient at a low angle of attack for both airfoils. Standard k - ε model gives a slightly low value of lift coefficient at low angle of attack and slightly high value of lift coefficient at high angle of attack for both airfoils. k-ω SST model, Spalart-Allmaras model, Transition k-kL - ω model, and γ-Rⅇθ Transition SST model can predict drag coefficient reasonably at low angle of attack. At a high angle of attack, however, no turbulence model is able to give a satisfactory prediction for lift coefficient as well as drag coefficient, which implies that these models are unable to predict post-stall characteristics. NACA 2412 airfoil produces more lift coefficient than that of the NACA 0012 airfoil at all angles of attack. Moreover, the drag coefficient of NACA 2412 airfoil is less than that of the NACA 0012 airfoil, which implies that NACA 2412 airfoil exhibits better aerodynamic performance. The lift to drag coefficient ratio of NACA 2412 airfoil is also higher than that of the NACA 0012 airfoil indicating NACA 2412 airfoil to be more fuel economic.
AIRCRAFT POSITIONING USING MULTIPLE DISTANCE MEASUREMENTS AND SPLINE PREDICTION
Authors: Ostroumov Ivan , Marais Karen , Kuzmenko Nataliia
Published: March 2022

During the crucial phases of take-off, initial climb, approach, and landing where aircraft are close to the ground, Global Navigation Satellite Systems (GNSS) signal strength may not be sufficient to guarantee safe operation, especially in the presence of potential interference, malicious or otherwise, from ground equipment. When the GNSS location is lost, aircraft typically revert to other navigation aids. The most accurate navigation aid is Distance Measuring Equipment (DME). However, whereas GNSS location is triangulated, the navigation equipment on-board aircraft can only measure two DME signals simultaneously. Therefore, location based on DME tends to be accurate only to hundreds of meters, compared to meters for GNSS. A new approach is presented for positioning using multiple DMEs. The approach is based on regression analysis for prediction of DMEs distances in time of measurement. This approach increases positioning accuracy due to availability of multiple DMEs data in the system of navigation equations. Spline functions were used in a regression model in order to achieve the most accurate prediction values. An approach was verified using real flight data and shown the decreasing of navigation system error on value depending on availability and geometry of ground stations locations.

Households are economic actors that play a significant role in the economic condition. Thus, households’ consumption expenditures are a variable that deserves a through analysis in an economy. This study aims to identify the impact of financial technology on household consumption by using the theory of the absolute income hypothesis. We use the partial adjustment model (PAM) approach and the Chow test to detect the structural change on households’ consumption function in Indonesia with the observation period of 1990–2017. The results demonstrate that Indonesian households’consumption function exhibits structural change because of the development of financial technology 3.0 era that started in 2000. Besides, the partial adjustment model also suggests that financial technology positively affects Indonesian households’consumption in both short-run and long-run. The findings imply that on the one hand, the findings are a positive signal to rely on finteh as the factor that encourages economic growth in Indonesia. On the other hand, the results indicate that fintech motivates the public to be more consumptive that will potentially lead to higher inflation rates.

In 2017, the California-Kepler Survey (CKS) published its first data release (DR1) of high-resolution optical spectra of 1305 planet hosts. Refined CKS planet radii revealed that small planets are bifurcated into two distinct populations, super-Earths (smaller than 1.5 R
⊕) and sub-Neptunes (between 2.0 and 4.0 R
⊕), with few planets in between (the “radius gap”). Several theoretical models of the radius gap predict variation with stellar mass, but testing these predictions is challenging with CKS DR1 due to its limited M
⋆ range of 0.8–1.4 M
⊙. Here we present CKS DR2 with 411 additional spectra and derived properties focusing on stars of 0.5–0.8 M
⊙. We found that the radius gap follows R

p
∝ P

m
with m = −0.10 ± 0.03, consistent with predictions of X-ray and ultraviolet- and core-powered mass-loss mechanisms. We found no evidence that m varies with M
⋆. We observed a correlation between the average sub-Neptune size and M
⋆. Over 0.5–1.4 M
⊙, the average sub-Neptune grows from 2.1 to 2.6 R
⊕, following

R

∝

with α = 0.25 ± 0.03. In contrast, there is no detectable change for super-Earths. These M
⋆–R

p
trends suggest that protoplanetary disks can efficiently produce cores up to a threshold mass of M

c
, which grows linearly with stellar mass according to M

c
≈ 10 M
⊕(M
⋆/M
⊙). There is no significant correlation between sub-Neptune size and stellar metallicity (over −0.5 to +0.5 dex), suggesting a weak relationship between planet envelope opacity and stellar metallicity. Finally, there is no significant variation in sub-Neptune size with stellar age (over 1–10 Gyr), which suggests that the majority of envelope contraction concludes after ∼1 Gyr.
L’ouverture de la fiction, manifestation d’un verrouillage institutionnel : le cas du site internet Pottermore et de la franchise Harry Potter
Authors: Nicolas Agathe
Published: March 2022

Cet article présente les enjeux de pouvoir et les rapports de force façonnant la franchise Harry Potter et son important cortège de fictions, produits, marques et entreprises dérivés, à travers une étude du site internet Pottermore. Comment Pottermore peut-il paradoxalement être défini à la fois comme un nouveau moyen de déployer la fiction Harry Potter et comme une part d’une stratégie de verrouillage de l’univers fictionnel ? Cette problématique est traitée suivant deux axes principaux : une analyse de la manière dont Pottermore se fait le lieu d’un déploiement et d’un renouveau de l’univers Harry Potter, afin de mettre en évidence la stratégie globale de contrôle et de verrouillage mise en place pour la franchise ; une étude de Pottermore comme enjeu des rapports de force et des jeux de pouvoir entre deux acteurs clés : J.K. Rowling et Warner Bros.
L’Égypte dans la Première Guerre mondiale : l’Établissement du protectorat comme élément de fragilisation de la domination britannique
Authors: de Gayffier-Bonneville Anne-Claire
Published: March 2022

Le 18 décembre 1914, un protectorat britannique sur l’Égypte est proclamé. La présence britannique en Égypte se normalise sur le schéma d’autres situations coloniales. Or le changement de statut imposé à l’Égypte en raison de la guerre, loin de consolider le pouvoir et la présence britanniques, comme espéré, les fragilise. La multiplication des dysfonctionnements et maladresses dans la prise en main du protectorat est une première cause de fragilité. La seconde tient à la réception de ce nouveau statut par les Égyptiens. Ceux-ci sont déçus de ne pas voir leur pays gagner en autonomie. Enfin, le contexte d’une guerre qui se prolonge oblige les Britanniques à solliciter l’aide de la population locale, contrairement à ce qu’ils avaient promis au début du conflit. Les difficultés du quotidien et le non-respect de l’engagement pris suscitent la colère de la population qui met en cause la structure même du protectorat.
Israël 1967-1977 : les grandes mutations au gré des guerres
Authors: Cohen-Muller Rina
Published: March 2022

La période allant de 1967 à 1977 est marquée par l’euphorie de la victoire militaire de la guerre de 1967 qui a radicalement transformé la réalité israélienne. Le jeune pays dirigé par le mouvement sioniste socialiste définissant Israël comme un État social et comme la seule démocratie au Proche-Orient bascule dans un système néolibéral d’économie de marché tout en devenant une puissance militaire. Cet article analyse ce basculement, qui a eu des conséquences sur tous les domaines de la vie israélienne. Cette période a fait apparaître les clivages (juifs-arabes ; gauche-droite ; religieux-séculiers ; centre-périphérie ; ashkenazim - mizrahim ) qui la caractérisent aujourd’hui, fixant les paramètres du conflit israélo-palestinien. D’une société qui se voulait melting pot et rassemblement des exilés, Israël devient un pays pluriculturel, voire multicommunautaire.

Les anciens combattants de la Première Guerre mondiale et l’État. Le cas des États-Unis
Authors: Burtin Olivier
Published: March 2022

Cet article propose de réorienter la recherche sur les anciens combattants dans l’entre-deux-guerres. En s’appuyant sur une synthèse de l’historiographie nord-américaine, qui est rarement mise en discussion avec l’européenne, il démontre que l’étude des politiques publiques pour vétérans permet d’approcher sous un angle nouveau la question plus large de leur relation avec l’État et la société civile. L’article retrace pour ce faire le rôle crucial joué par les anciens combattants dans le développement de l’État-providence aux Etats-Unis entre la fin de la guerre de Sécession et la Seconde Guerre mondiale, en s’attachant à montrer non seulement comment leurs avantages sociaux furent l’objet de l’action politique mais aussi comment ils en conditionnèrent les termes.
Remettre les corps en place à la Libération : exhumations, identifications et transferts après 1944
Authors: Dreyfus Jean-Marc
Published: March 2022

Dès la libération du territoire français, des recherches furent engagées pour retrouver les corps des disparus et de nombreuses exhumations eurent lieu. Au moins 70 000 cadavres furent exhumés et réinhumés. Cet article veut décrire ces exhumations et les catégoriser en fonction des catégories de corps telles qu’elles ont été définies à ce moment-là. Les agents de ces exhumations seront ensuite décrits, avec en particulier la recentralisation des décisions d’exhumations au sein du ministère des Anciens combattants et l’intervention progressive des autorités traditionnelles en charge du traitement des cadavres : magistrats et médecins légistes. Enfin des interprétations seront proposées : précédents de l’après-Première Guerre mondiale et rétablissement de la légalité républicaine.
Comprendre et gérer les paradoxes organisationnels inhérents à la « transformation digitale » : une nécessité managériale
Authors: Perrin Aurélie
Published: March 2022

La transformation digitale dans le secteur médico-social questionne les pratiques professionnelles et créée d’importantes difficultés dans les organisations. De ce contexte particulier, émergent les paradoxes organisationnels (Lewis, 2000) qui mettent en jeu l’équilibre de l’organisation. Le cadre de proximité voit alors la nécessité de prendre en compte ces paradoxes inhérents au changement et d’adopter des stratégies particulières de gestion, appelées « pratiques paradoxales organisationnelles » (Josserand et Perret, 2003) pour ainsi dépasser « vertueusement » ces tensions. Notre étude exploratoire porte sur l’émergence de paradoxes organisationnels lors du déploiement d’un progiciel, au sein d’établissements médico-sociaux. Cette recherche amène une double contribution aux équipes de management ; à la fois la reconnaissance de paradoxes perçus par une équipe et à la fois la mise en œuvre de pratiques de gestion par le cadre de proximité.
