Published: February 2021

Teknologi informasi dan komunikasi memang tidak dapat dipisahkan dan perpaduan keduanya semakin meningkat dengan hadirnya internet dalam memperoleh informasi dan melakukan komunikasi dikalangan masyarakat, bahkan sekolah–sekolah juga sudah menerapkan teknologi informasi ini untuk meningkatkan dan mengembangkan kinerja guru dan pembelajaran bagi para siswa. Adapun nilai akademik siswa adalah data yang sangat penting untuk sekolah, siswa terutama untuk orangtua siswa karena itu merupakan nilai acuan dari hasil belajar anak mereka selama disekolah. Salah satunya di SDN Keroncong 3 Tangerang, sistem pengolahan nilai akademik siswa saat ini masih menggunakan cara manual seperti, wali kelas mengelola nilai siswa dari guru untuk semua mata pelajaran serta pada proses pengolahan nilai siswa masih kurang efektif, penggunaan kertas yang jumlahnya banyak dan adanya kesalahan dalam mengelola data nilai siswa serta proses pengolahan nilai untuk pengisian pada rapor siswa masih memerlukan waktu yang cukup lama. Oleh karena itu, penulis tertarik untuk melakukan penelitian. Dalam penelitian ini dibangun sebuah sistem yang lebih baik dalam proses pengolahan nilai akademik siswa yang bermanfaat untuk membantu, mempercepat dan mempermudah proses penilaian siswa. Perancangan sistem informasi nilai akademik siswa yang berbasis web ini menggunakan metode PHP (Page Hypertext Prepocessor) untuk membantu proses penilaian menjadi lebih cepat, tepat dan akurat; kemudian UML (Unified Modeling Languange) untuk menggambarkan rancangan sistem yang berjalan dan dibantu dengan MySQL (My Structure Query Language) sebagai database pendukungnya

Published: February 2021

Pengenalan profesi sejak dini sangatlah bermanfaat bagi anak untuk menambah wawasan mengenai profesi, sehingga orangtua bisa mengarahkan anak pada cita-cita di masa depan. Pengenalan profesi bisa didapat anak dari guru atau orangtua, namun tentu profesi-profesi yang diajarkan terbatas. Media pembelajaran yang biasanya digunakan hanya buku bergambar atau dengan lisan, sehingga anak mudah bosan dalam belajar. Smartphone Android bisa dijadikan sebuah media pembelajaran. Oleh karena itu, perlunya sebuah aplikasi pengenalan profesi pada anak usia dini berbasis android untuk mengenalkan profesi secara interaktif pada anak. Aplikasi ini didukung dengan desain gambar yang menarik, backsound serta animasi untuk memberikan informasi mengenai profesi. Sistem dibangun dan dirancang menggunakan Adobe Animate CC 2019 dan Adobe Illustrator sebagai pengolah desain.
Abdominal Arteryel Vasküler Varyasyonlarının Tespitinde Çok Kesitli Bilgisayarlı Tomografi
Authors: TOPCU Adem , İKİZCELİ Türkan , OĞUZ KÖSEHAN Dilek
Published: February 2021

Amaç: Çok Kesitli Bilgisayarlı Tomografi ile abdominal aorta ve ana dallarında izlenen varyasyonları saptamak, bu varyasyonları sınıflandırmak ve sıklıklarını ortaya koymaktır.
Gereç ve Yöntem: Ocak 2010 –Mart 2012 tarihleri arasında intravenöz kontrast madde verilmesini takiben dinamik abdomen BT tetkiki yapılan 19-91 yaşları arasındaki 390 erişkin hastanın verileri cinsiyet ve yaş farkı gözetilmeksizin retrospektif olarak çalışmaya alındı. Geçirilmiş solid organ ya da abdominal ana damarsal anatomiyi etkileyebilecek cerrahi öyküsü olan hastalar çalışmaya dahil edilmedi. Veriler iş istasyonunda değerlendirildi. Abdominal aorta ve dallarında görülen varyasyon sıklıkları incelendi ve her iki cinsiyet arasında varyasyon sıklıkları açısından anlamlı bir farklılık olup olmadığı araştırıldı.
Bulgular: Çalışmamızda abdominal aorta ve ana dallarında hepatik arter, gastroduedonal arter, çöliyak arter ve renal arterlerde sıklıkla varyasyon saptandı. Splenik arter ve sol gastrik arterde ise diğer damarsal yapılara göre daha az varyasyon izlendi. Varyasyon sıklıkları açısından cinsiyetlere göre istatistiksel anlamlı farklılık saptanmadı.
Sonuç: Hepatik ve renal arterlerde varyasyonlar sık görülmektedir. Bu varyasyonların önceden bilinmesi özellikle karaciğer, böbrek nakilleri ve bu organlara yönelik yapılacak girişimsel radyolojik işlemlerde büyük önem arz etmektedir.
Diatoms from small ponds and terrestrial habitats in Deserta Grande Island (Madeira Archipelago)
Authors: Gonçalves Vítor , Ritter Catarina , Marques Helena , Teixeira Dinarte , Raposeiro Pedro
Published: February 2021

Freshwater diversity, and diatoms in particular, from Desertas Islands (Madeira Archipelago, Portugal) is poorly known, although the Islands are protected and became a Natural Reserve in 1995. During two field expeditions in 2013 and 2014 to Deserta Grande Island, several freshwater and terrestrial habitats were sampled. The analysis of these samples aims to contribute to the biodiversity assessment of the freshwater biota present in Deserta Grande Island. Here, we present the diatom diversity in Deserta Grande Island resulting from that survey. This study contributes to improve the knowledge of Madeira Archipelago freshwater diversity, particularly in the Desertas sub-archipelago.

To our knowledge, we present the first diatom data for the Desertas sub-archipelago. This work resulted in a list of 60 diatom taxa for Deserta Grande, from which 57 were identified to species level. From the 60 new records for Desertas sub-archipelago, 30 of them were also new records for Madeira Archipelago. Several specimens could not be assigned to a known species and may be new diatom species not yet described.
First records of the pest leaf beetle Chrysolina (Chrysolinopsis) americana (Linnaeus, 1758) (Coleoptera, Chrysomelidae) in Cyprus - a study initiated from social media
Authors: Hadjiconstantis Michael , Zoumides Christos
Published: February 2021

The leaf beetle Chrysolina (Chrysolinopsis) americana (Linnaeus, 1758), commonly known as the Rosemary beetle, is native to some parts of the Mediterranean region. In the last few decades, it has expanded its distribution to new regions in the North and Eastern Mediterranean basin. Chrysolina americana feeds on plants of the Lamiaceae family, such as Rosmarinus officinalis, Lavandula spp., Salvia spp., Thymus spp. and others. Chrysolina americana is considered a pest, as many of its host plants are of commercial importance and are often used as ornamentals in house gardens and green public spaces. In this work, we report the first occurrence of C. americana in Cyprus and we present its establishment, expansion and distribution across the Island, through recordings for the period 2015 – 2020. The study was initiated from a post on a Facebook group, where the species was noticed in Cyprus for the first time, indicating that social media and citizen science can be particularly helpful in biodiversity research.
Course à la suprématie technologique et géopolitique de l’innovation
Authors: Clerc Philippe , Cappe de Baillon Patrick
Published: February 2021

La course à la suprématie technologique, notamment dans les domaines de l’IA, de l’informatique quantique et de la 5G, entre les deux « hégémons » américain et chinois, dessine une géopolitique de l’innovation qui laisse peu de place à une Europe en mal d’autonomie stratégique. Comment reprendre la main ? Tout d’abord, en réajustant nos grilles de lecture des rapports de forces technologiques et économiques mondiaux, ainsi que des stratégies sophistiquées de nos grands concurrents, États-Unis et Chine. Face à ces deux géants, qui ne respectent pas les règles du jeu, usant de la force et de la ruse (arme de l’extra-territorialité du droit américain, interventionnisme de l’État chinois, « encerclement cognitif »), « l’agir stratégique » européen devra se traduire par une refonte de la politique de concurrence et une stratégie industrielle offensive. Pour cela, l’Union européenne devra continuer de déployer et de renforcer son arsenal de sécurité économique, redéfinir rapidement sa doctrine à l’égard des investissements étrangers. Cette stratégie pro-active s’impose aussi si l’on veut gagner le combat en cours pour la maîtrise des données privées et des données des entreprises.
Territoire(s) et intelligence économique
Authors: Haberbusch Benoît
Published: February 2021

Dans le contexte de la crise de la Covid-19, face à un environnement économique de plus en plus incertain et à des entreprises fragilisées, l’Intelligence économique (IE) représente un enjeu majeur pour la Gendarmerie nationale (GN). Mais cette préoccupation n’est pas nouvelle pour la GN : pleinement inscrite dans la politique publique d’IE lancée en 2005, elle a su déployer un arsenal d’outils et de solutions et tirer profit de son maillage territorial pour s’affirmer auprès des acteurs de la vie économique du pays. Son expertise en matière de sécurité économique, fruit d’une longue histoire, en fait un référent apprécié en matière de prévention des risques qui pèsent sur les entreprises (et les particuliers) avec l’apparition notamment des nouveaux territoires numériques.

Crise de la Covid-19 dans le secteur du tourisme
Authors: Blanchet Cyril
Published: February 2021

Cet article de recherche permet de comprendre comment l’information se transmet en période de crise et quelle coopération se construit entre des acteurs médiatiques et académiques spécialisés sur le secteur du tourisme. Nous partirons de l’hypothèse qu’en période de crise, une collaboration des compétences se construit pour apporter des informations fiables et de qualités aux lecteurs. À travers une veille sectorielle des médias et des revues scientifiques pendant (17 mars 2020 – 11 mai 2020) et après le confinement (11 mai 2020 – 11 septembre 2020), nous illustrerons les différentes sources d’informations portées par chacun des acteurs, qu’ils soient médiatiques ou académiques.

Authors: Arnaux Sébastien , Da Re Claudia
Published: February 2021

Situé autour d’un ancien pont-aqueduc romain, le Pont du Gard est un site patrimonial exceptionnel, qui accueille un million de visiteurs par an. Il bénéficie du label Patrimoine mondial Unesco et appartient à la Réserve de biosphère des Gorges du Gardon . Face à la première vague de la Covid, le site a dû arrêter, puis adapter son activité. Grâce à la résilience de l’équipe et à la détermination de son directeur, la saison 2020 a été maintenue. La crise devient aussi un moment de réflexion stratégique. Comment promouvoir un tourisme durable, une offre touristique de qualité, adossée au développement économique de la région, mais dans une logique de sauvegarde et de développement durable ? Sébastien Arnaux identifie deux points clés : le renforcement du réseau territorial de tous les acteurs du secteur et la responsabilisation des usagers à l’égard de leur territoire.
Le capital de l’imaginaire
Authors: Aanza Sinzo
Published: February 2021

Le romancier et plasticien Sinzo Aanza interroge la place de l’artiste face au pouvoir depuis l’époque précoloniale jusqu’à nos jours dans le Congo contemporain. Ce qu’il appelle le « capital de l’imaginaire » se déploie avec et contre le pouvoir sur le marché de la valeur : tandis que les vendeurs de masques sont asservis par des discours d’authenticité fantasmée sur de l’art rituel, d’autres artistes s’attachent à dire l’expérience coloniale, l’exploitation des corps et des terres, dont les prédations minières contemporaines sont la continuation. C’est le rôle du poète et de l’artiste congolais qui est analysé en définitive, eux qui sont porteurs d’imaginaires tournés vers le futur et le monde.
Tanina ntoto !
Authors: Kisukidi Yala
Published: February 2021

L’article entend constituer la grand-mère comme figure centrale de transmission, comme personnage politique radical : figure de récit, figure de continuité mémorielle là où la colonisation a sapé l’autorité des lignées paternelles. Se décalant d’un récit qui pense la colonisation comme une castration symbolique des pères, l’auteure interroge les lignées féminines et leur pouvoir de transmission de trames narratives et mémorielles. La grand-mère est érigée en force politique, capable de défaire l’autorité patriarcale et de recréer des liens défaits. La force des « petites histoires » racontées par les grand-mères face aux défaites de la « grande histoire » des pères : tel est le pouvoir des fabulations politiques de soi qui s’inventent au-delà ou contre les identités normatives et produisent de nouveaux imaginaires politiques.
Champ politique et champ musical populaire
Authors: Tsambu Léon
Published: February 2021

Le politique et le chanteur : deux figures qui semblent bien éloignées mais que l’auteur rassemble en partant de la scène kinoise. Stratégie de subversion, culte de la personnalité, culture du clash, soutien de supporters, fonctionnement en factions : avec humour, l’auteur dresse des parallèles entre les univers musicaux et politiques pour, d’une part, souligner combien la musique porte une large part de politique et pour, d’autre part, déconstruire l’autorité du champ politique par la dérision. La dictature est ainsi lue comme le plébiscite, par les masses, d’hommes de scènes, passés maîtres dans la gestion des slogans et des bonnes répliques. Les stars de la chanson, de leur côté, sont partie prenante des campagnes électorales et participent aux stratégies de marketing de la scène politique. Au-delà des jeux de rapprochement, l’article interroge la fabrication des élites, l’espace médiatique, la création des « stars » et l’usage de la parole politique.
Ré-enchanter l’Afrique
Authors: Mbembe Achille
Published: February 2021

Au cours de cet entretien mené par Yala Kisukidi, Achille Mbembe revient sur les thèmes clés de son ouvrage  Brutalisme  (2020) : la définition de l’idée d’« Afrique », la nécessité de sortir d’une « histoire de la prédation » et de réinvestir des utopies par le « ré-enchantement », la revalorisation d’une « politique du soin » tandis que la terre est endommagée, la création d’un espace africain de libre circulation sont évoquées tour à tour. Convoquant les écrivains Amos Tutuola et Sony Labou Tansi, Mbembe souligne le rôle de l’imaginaire, et singulièrement de la littérature, dans la fabrique des utopies de demain. L’art, entendu comme réserve de vie et de possibles, constitue une ressource pour penser les migrations contemporaines et imaginer d’autres modèles alternatifs au modèle actuel néolibéral. Face à la criminalisation des circulations, le pillage des ressources, la violence du « brutalisme » contemporain, Mbembe en appelle à une « politique du soin » capable d’inclure, depuis l’Afrique, la question du commun et du partage de la Terre.
L e turfurisme ou L’invention du turfu
Authors: Fofana Makan
Published: February 2021

Pour entrer dans l’ère post-banlieue il faut passer du questionnement sociologique qui décrit le triste présent au questionnement philosophique qui invente le futur. La banlieue du turfu est un espace de connexion, producteur d’une culture hybride entre banlieue et monde, qui explore la banlieue comme une contrée lointaine et le monde comme une banlieue et trace une multiplicité de lignes de fuite possibles.
« A » comme Amérique, Amazonie et abeilles
Authors: Szaniecki Barbara
Published: February 2021

« Amérique latine » est un nom empreint d’un passé colonial qui ne correspond aucunement à la diversité de ce vaste continent. Oser un redesign  de l’Amérique latine signifie ici ouvrir des possibilités… plutôt que conclure des projets. Cela implique de revoir en traits rapides l’histoire de la formation des États-nations et les conséquences récentes du national-développementisme. Ensuite, de présenter quelques initiatives biopolitiques dans les enchevêtrements d’une biozone partagée par plusieurs nations latino-américaines. Enfin, de suivre les « abeilles sans dard » de la forêt jusqu’en ville pour, au bout du chemin, grâce à leurs pollinisations et essaimages, percevoir les contours d’une ZAD amazonienne en formation.
Généalogie du gouvernement Bolsonaro
Authors: Cocco Giuseppe
Published: February 2021

L’arrivée au pouvoir de Jair Bolsonaro au Brésil a eu lieu dans l’affirmation d’un nouveau warfare  : une guerre diffuse où la distinction entre l’ami et l’ennemi devient floue. C’est un double dispositif qui s’est mis en place. D’une part, le retour aux affaires de l’armée brésilienne dans le cadre des missions de paix menées pendant les gouvernements de la gauche, en Haïti et dans les favelas de Rio de Janeiro. D’autre part, la polarisation par Lula et la gauche a préparé la mobilisation d’une nouvelle extrême droite. Avec la crise du Covid, grâce à la mise en place d’un revenu de base, le «  lulismo  » se transmute en «  bolsonarismo  ».
Radiographie du commandantisme vénézuélien
Authors: Martínez Jeudiel , Andréani Fabrice
Published: February 2021

Né du culte militaire et d’un coup d’État raté, le « chavisme » est devenu un phénomène politique. Après avoir survécu au coup d’État de 2002, il a commencé à coloniser l’État dans un processus progressif mais continu dans lequel est apparu un nouveau type de militarisme de gauche que l’on pourrait appeler le «  comandantismo » . Ce régime est entré en crise avec la mort de Chavez et la chute des prix du pétrole. Avec Maduro, son successeur, une tentative de réforme a connu le succès dans la lutte pour le pouvoir mais a échoué à obtenir des changements mettant fin à un désastre systémique qui a commencé il y a plus de dix ans.

Published: February 2021

La pandémie de la Covid-19 a entraîné l’accélération du processus de démantèlement des institutions démocratiques dans de nombreux pays du continent sud-américain. Mais les racines de ce processus d’affaiblissement des pratiques démocratiques sont bien antérieures. Dans cet article, nous retraçons quelques moments forts de ce remaniement de la démocratie en Équateur tout au long du XXI e  siècle. Nous analysons les limites des progressismes et leur contribution à la consolidation d’un État intense en pratiques autoritaires et faible en participation et en démocratie.
Pourquoi Lucho et David ont remporté les élections en Bolivie ?
Authors: Solón Pablo , De Roo Priscilla
Published: February 2021

Le MAS a remporté les élections présidentielles boliviennes d’octobre 2020 dès le premier tour, avec 55,1 % des voix. Pablo Solón, ancien ministre d’Evo Morales, énumère dans cet article les raisons de ce triomphe et trace les défis qui s’imposent au nouveau gouvernement du président élu, Luis Arce. De fait, c’est une phase post Evo Morales qui s’ouvre, dans un pays profondément marqué par la pandémie, l’écocide, la corruption, les atteintes à l’état de droit, ainsi que par grave crise économique. La clé pour relancer un « processus de changement » repose dans la capacité d’autogestion et d’autonomie des organisations sociales.
Impacts of insect consumption on human health
Authors: Stull V.J.
Published: February 2021

Edible insects represent an understudied food resource that may promote human health. They characteristically contain ample protein, healthy fatty acids, minerals, and vitamins, and have been touted for their environmental benefits given their efficient resource use. While numerous in vitro, animal, and nutrient quantification studies have elucidated a framework of potential health impacts of entomophagy, few have measured direct health outcomes. This review investigates and summarises existing evidence on health impacts derived exclusively from human interventions. A systematic literature search was conducted in three databases: SCOPUS, Web of Science, and PubMed. Out of 1,691 initial results, only nine studies met the inclusion criteria. In these limited studies, insects were shown to have potential to: (1) promote growth and influence iron status when added to complementary foods; (2) modulate gut microbiota with some prebiotic effects; and (3) provide amino acids similar to soya protein. One study also provided isolated evidence that an insect-herb mixture could possibly reduce symptoms of chronic obstructive pulmonary disease when added to routine treatment. Importantly, results reveal a significant lack of human subjects research directly measuring health outcomes from insect consumption. Findings from the included studies indicate that insects are generally safe and offer both beneficial and neutral outcomes compared to other foods. These discoveries, in tandem with extensive evidence from non-human studies, support claims that insect consumption could further enhance health by addressing micronutrient deficiencies or promoting gut health. There are also other plausible health promoting properties of insects that could help ameliorate complications with hypertension and other non-communicable disease. More rigorous and better controlled human intervention trials are fundamental to confirm health benefits and better assess risks associated with entomophagy, while also addressing unanswered questions regarding nutrient bioavailability, the fate of dietary chitin, and in vivo activity of bioactive peptides.
Corneal Cross-linking at the Slit Lamp
Authors: Hafezi Farhad , Richoz Olivier , Torres-Netto Emilio A. , Hillen Mark , Hafezi Nikki L.
Published: February 2021

PURPOSE:

To describe a new surgical technique where corneal cross-linking (CXL) (to treat corneal ectasias) and photo-activated chromophore for keratitis-CXL (PACK-CXL) are performed while the patient is seated in an upright position at the slit lamp.

METHODS:

Topical anesthesia is applied in the waiting room, 10 minutes before the procedure. Once in the office or procedure room, eyelids and periorbital areas are disinfected with chloramphenicol and the patient is seated at the slit lamp. Epithelial debridement is performed with a cotton swab soaked in freshly prepared 40% ethanol, using 70 seconds of tapping, followed by gentle pressure to remove the epithelium. The patient is placed in the supine position for riboflavin application for 10 minutes. Stromal thickness is assessed using ultrasound pachymetry after 5 and 10 minutes. Finally, the patient is returned to the slit lamp to receive ultraviolet irradiation.

RESULTS:

CXL at the slit lamp is an easy-to-perform technique that substantially reduces the infrastructure needed to perform CXL and PACK-CXL procedures.

CONCLUSIONS:

A significant advantage of allowing CXL treatment at the slit lamp is that CXL technology can now be used in clinics that do not have easy access to an operating room infrastructure. Slit-lamp CXL can also reduce procedure costs by eliminating the technical fees related to the use of an operating room, making this treatment not only more accessible for patients, but also affordable.

Two-Year Follow-up of Intracorneal Ring Segments Implantation in Adolescent Patients With Keratoconus
Authors: Peris-Martínez Cristina , Hernández-Díaz Mikhail , Roig-Revert Maria José , Alfonso-Muñoz Enrique , Montolío-Marzo Santiago , Monsálvez-Romín Daniel
Published: February 2021

PURPOSE:

To evaluate the visual, refractive, topographic, and aberrometric outcomes after intracorneal ring segments (ICRS) implantation in adolescent patients with keratoconus.

METHODS:

A retrospective longitudinal study was undertaken with a total of 61 eyes from 47 patients with keratoconus, aged between 13 and 18 years, implanted with a Ferrara-type ICRS. Topography (flattest keratometry, steepest keratometry, and asphericity), uncorrected distance visual acuity (UDVA), corrected distance visual acuity (CDVA), refractive error (sphere and cylinder), and aberrometric measurements (spherical aberration and vertical coma) were evaluated before surgery and at 1 month, 6 months, 1 year, and 2 years after surgery.

RESULTS:

UDVA exhibited a statistically significant increase at all times from 1 month to 2 years postoperatively (
P
< .001), whereas CDVA showed a statistically significant improvement at 1 month, 6 months, and 2 years (
P
< .002), but dropped in significance at 1 year postoperatively (
P
= .097). The refractive error analysis showed no variation in statistical significance in the sphere (
P
= .712) after 2 years. The cylinder presented a statistically significant decrease in diopters at all times from preoperatively to 2 years postoperatively (
P
< .007). Steepest keratometry manifested a statistically significant decrease in steepness at all times after surgery (
P
< .001), whereas flattest keratometry lost significance at 1 year (
P
= .298) and 2 years (
P
= .053) postoperatively. There was no statistically significant change in the spherical aberration at any of the measured times. The vertical coma was only significantly different at 2 years postoperatively (
P
= .001).

CONCLUSIONS:

ICRS implantation is a safe and effective treatment for improving visual and corneal morphological parameters as shown at 2 years of follow-up in adolescent patients with keratoconus. It is a good option to flatten and regularize the cornea and to temporarily improve the quality of life of young patients and delay the need for keratoplasty.

Explicaciones históricas de la huella genética norteafricana en el noroeste de Iberia
Authors: Peterson David
Published: February 2021

Se analizan siete estudios recientes sobre la huella genética norteafricana en Iberia. En todos ellos se observan las mayores concentraciones de características genéticas asociables con el Magreb en el noroeste de la Península Ibérica, una región no sólo alejada de África sino también sujeta al control político andalusí durante menos tiempo que prácticamente cualquier otra región peninsular. Los intentos para buscar un contexto histórico para tan anómala distribución han sido lastrados por una lectura algo simplista de la historiografía, en detrimento de cualquier explicación altomedieval, favoreciendo en cambio soluciones alternativas más historio-gráficamente problemáticas. En consecuencia, estos estudios han sido generalmente ignorados por los medievalistas, así agravando la falta de diálogo entre ambas disciplinas. Sugerimos que la percibida paradoja entre un breve periodo de control político y una profunda huella genética debe servir para cuestionar la interpretación tradicional de los acontecimientos del siglo VIII, y así obligarnos a contemplar una mayor influencia Bereber en el noroeste, en vez de conducir a la marginalización por parte de los historiadores de tan llamativos resultados.
Lidiar con fieras: el árabe y el hebreo en el Tesoro de Covarrubias
Authors: Hasson Or
Published: February 2021

Este estudio examina la representación del árabe y del hebreo en el Tesoro de la lengua castellana o española (Madrid, 1611) desde una perspectiva comparada. Partiendo del discurso ideológico y metalingüístico del lexicógrafo, trato de reconstruir sus postulados en torno a las respectivas historias del hebreo y árabe, la relación entre sí y el papel que desempeñan en la historia del español tal como la narra Covarrubias. A la luz de estos postulados, y teniendo en cuenta los conocimientos del lexicógrafo, así como las fuentes e informantes a los que recurre, examino algunas de sus prácticas etimológicas, y, en particular, sus intentos de emplear sus conocimientos de la gramática y léxico hebreos para iluminar etimologías arábigas de vocablos castellanos. Combinando el nivel ideológico del texto con el técnico, reflexiono sobre la interacción entre saber e ignorancia en el estudio de las lenguas semíticas en el Tesoro.
Cómo aprendió árabe Campomanes: sobre el aprendizaje de lenguas orientales en la Ilustración española
Authors: Rodríguez-Mediano Fernando
Published: February 2021

Pedro Rodríguez Campomanes fue una de las figuras más destacadas de la Ilustración española. Uno de sus principales intereses fue el de la erudición arábiga. Conocemos su relación con proyectos institucionales, ligados, por ejemplo, a la Real Academia de la Historia, pero ignoramos cuál fue su relación directa con la lengua árabe, cómo la aprendió o cuál fue su conocimiento de la tradición orientalista. En este artículo estudio cómo aprendió árabe Campomanes, a partir de documentos de su archivo personal, y también de manuscritos de la Biblioteca Nacional de España pertenecientes a un colega de Campomanes, José Carbonel y Fogasa. Carbonel y Campomanes estudiaron juntos árabe con Miguel Casiri, y su documentación proporciona materiales de interés, no sólo para el aprendizaje del árabe y de otras lenguas extranjeras en el s. XVIII, sino en general sobre la historia del orientalismo europeo de esa época.

Published: February 2021

Critical thinking skills are very important to have for students given the rapid distribution of information. To promote the critical thinking skills of the student, it could be done by including critical thinking learning in a formal learning environment. However, for the purpose of increasing this skill could be achieved, it required the motivation to learn. This study aimed to increase critical thinking skills and students' motivation through the implementation of an inquiry mind map tool. The study used a quasi-experimental group with a non-equivalent control-group pretest-posttest. The experimental class used an inquiry learning assisted inquiry mind map tool, whereas the control class requires that conventional learning. The sample consisted of 206 students from different schools and different genders. Data on critical thinking skills used essay tests referred to indicators from Sari in 2019. Motivation data learning taken from instrument motivation toward science learning from Tuan, Chin & Shied in 2005. Answers analyzed using ANCOVA. The research findings show that there were differences in the ability to think critically and students' learning motivation using an inquiry mind map tool. The results also examined no difference between school and gender on critical thinking skills and learning motivation. The results of the study show that the inquiry mind map tool was an impact on increasing critical thinking skills and learning motivation. It was recommended to be able to develop more other learning tools and learning model to improve critical thinking skills. Some im-plication was also provided in the article.

Authors: Ge Dongjun , Wang Xiaoyue , Liu Jingting
Published: February 2021

Developed countries regard preschool education as an important starting point and foundation for elite training. In recent years, preschool education has also attracted a growing attention in developing countries like China. Considering the significance of the teaching quality of preschool teachers to lifelong academic achievement, this paper designs a teaching quality evaluation model for preschool teachers based on deep learning. Firstly, a progressive system with a hierarchical structure was developed for the relevant evaluation indices. Then, the fuzzy comprehensive evaluation of each index layer and evaluation criterion was determined by the principle of fuzzy relationship synthesis. Finally, an evaluation prediction model was established based on extreme gradient boosting (XGBoost) algorithm and technology services’ ResNet (TS-ResNet), and proved effective and accurate through experiments. The research results provide a reference for the application of the proposed model in other evaluation prediction scenarios.

This paper presents a modification of a well-known routing protocol, namely Ad hoc On-Demand Distance Vector, as a solution to improve the performance of mobile ad hoc networks. We adapted the mobile agent technology as to novel metrics for routing in those networks. The metric is a function of the loss rate, the bandwidth and the end-to-end delay of the link. Indeed, we established a new tunable parameter to obtain a tradeoff between throughput and delay when computing the new metric. As a result, any routing protocol using this metric can al-ways choose a high-throughput and low-delay path between a source and a destination. Hence, the achievable performance of the mobile ad hoc networks has been improved remarkably with our modified routing protocol,

Abstract— Data Mining plays a decisive role especially in medical domain. Decision trees are predominant model in machine learning. Decision trees are simple and very effective classification approach. The decision tree identifies the utmost prime features of a given problem. One of the most common disease in India is Liver Cirrhosis. It is distinctly difficult to uncover Liver Cirrhosis in its initial stage. However early diagnosis of Liver Cirrhosis is highly important.The liver disease data set has a collection of distinguishing features that affect the healthy state of a patient. Machine Learning methods enable knowledge acquisition in early stages and use of this acquired knowledge plays an important role in solving problems like suppose if we want to predict whether the patient with the Liver Cirrhosis has also been suffering from Hepatitis C or not. In order to easily arrive at this knowledge certainly there is a need for fully integrated system. In this paper the collected Liver disease data set is analyzed and prognosticated whether the patient is suffering from liver cirrhosis or not.

In the 21st century, University educations are becoming a key pillar of social and economic life. It plays a major role not only in the educational process but also in the ensuring of two important things which are a prosperous career and financial security. However, predicting university admission can be especially difficult because the students are not aware of admission requirements. For that reason, the main purpose of this research work is to provide a recommender system for early predicting university admission based on four Machine Learning algorithms namely Linear Regression, Decision Tree, Support Vector Regression, and Random Forest Regression. The experimental results showed that the Random Forest Regression is the most suitable Machine Learning algorithm for predicting university admission. Also, the Cumulative Grade Point Average (CGPA) is the most important parameter that influences the chance of admission.

We described a human regulatory T cell (Treg) population activated by IgG+ B cells presenting peptides of the heavy C region (Fc) via processing of the surface IgG underlying a model for B cell–Treg cooperation in the human immune regulation. Functionally, Treg inhibited the polarization of naive T cells toward a proinflammatory phenotype in both a cognate and a noncognate fashion. Their fine specificities were similar in healthy donors and patients with rheumatoid arthritis, a systemic autoimmune disease. Four immunodominant Fc peptides bound multiple HLA class II alleles and were recognized by most subjects in the two cohorts. The presentation of Fc peptides that stimulate Treg through the processing of IgG by dendritic cells (DC) occurred in myeloid DC classical DC 1 and classical DC 2. Different routes of Ag processing of the IgG impacted Treg expansion in rheumatoid arthritis patients.

Coronavirus disease 2019 (COVID-19) is associated with immune dysregulation and cytokine storm. Exploring the immune-inflammatory characteristics of COVID-19 patients is essential to reveal pathogenesis and predict progression. In this study, COVID-19 patients showed decreased CD3+, CD4+, and CD8+ T cells but increased neutrophils in circulation, exhibiting upregulated neutrophil-to-lymphocyte and neutrophil-to-CD8+ T cell ratio. IL-6, TNF-α, IL-1β, IL-18, IL-12/IL-23p40, IL-10, Tim-3, IL-8, neutrophil extracellular trap–related proteinase 3, and S100A8/A9 were elevated, whereas IFN-γ and C-type lectin domain family 9 member A (clec9A) were decreased in COVID-19 patients compared with healthy controls. When compared with influenza patients, the expressions of TNF-α, IL-18, IL-12/IL-23p40, IL-8, S100A8/A9 and Tim-3 were significantly increased in critical COVID-19 patients, and carcinoembryonic Ag, IL-8, and S100A8/A9 could serve as clinically available hematologic indexes for identifying COVID-19 from influenza. Moreover, IL-6, IL-8, IL-1β, TNF-α, proteinase 3, and S100A8/A9 were increased in bronchoalveolar lavage fluid of severe/critical patients compared with moderate patients, despite decreased CD4+ T cells, CD8+ T cells, B cells, and NK cells. Interestingly, bronchoalveolar IL-6, carcinoembryonic Ag, IL-8, S100A8/A9, and proteinase 3 were found to be predictive of COVID-19 severity and may serve as potential biomarkers for predicting COVID-19 progression and potential targets in therapeutic intervention of COVID-19.

In Italy, to match medical doctors to specialty residencies, the Minister of Education organizes a national multiple choice questions exam composed of 140 items. The curriculum grants additional points based on the candidates’ grade average and graduation mark. Both national and international policies assume that curriculum scores can be evaluated in absolute terms, irrespective of the course attended by the candidate or its University of graduation. A fair inquiry over the current criteria of selection is not available to this day. Hence, this study aimed at investigating the degree of association between results in the Italian national residency test and the score given for each candidate’s curriculum. We calculated Spearman’s correlation coefficients between the score obtained at the 2019 test and curriculum scores. A moderate/high degree of correlation (rho=0.600) was reached. Spearman’s rho ranged from 0.447 to 0.788, considering the single Universities. We thus measured a modest but non-negligible between-University variability. As differences between test and curriculum scores across institutions may determine the admission or not to the residency for many candidates, the authors call for broader attention on the topic.
Gastric strangulation and perforation caused by a giant inguinal-scrotal hernia
Authors: Vinod Vijay Chander , Younis Muhammad Umar
Published: February 2021

Acute abdomen is always a challenging case presentation in an emergency department. A thorough clinical examination and prompt differential diagnosis and required investigations can save patients from potentially life-threatening conditions. We report the case of a 49-year-old gentleman who presented with a rare presentation of acute lower abdominal pain which initially mimicked renal colic (flank pain and dysuria), later as an upper gastrointestinal bleed manifested by massive hematemesis due to the stomach being pulled down into a giant inguinoscrotal hernia resulting in a gastric perforation. The patient underwent life-saving emergency midline open laparotomy. To our knowledge and as per the literature reviewed, this is an uncommon presentation of an acute lower abdomen pain wherein the gastric perforation due to a giant inguinoscrotal hernia masquerade as renal colic and posed a diagnostic challenge to the treating emergency physician.

OBJECTIVES:

Although studies in the field of emergency medical services (EMS) generally compare survival and hospital discharge rates, there are not many studies measuring the quality of cardiopulmonary resuscitation (CPR). In this study, we aimed to compare the mechanical chest compression device and paramedics in terms of CPR quality.

METHODS:

This is an experimental trial. This study was performed by the EMS of Ankara city (capital of Turkey). Twenty (ten males and ten females) paramedics participated in the study. We used LUCAS™ 2 as a mechanical chest compression device in the study. Paramedics applied chest compression in twenty rounds, whereas mechanical chest compression device applied chest compression in another set of twenty rounds. The depth, rate, and hands-off time of chest compression were measured by means of the model's recording system.

RESULTS:

The median chest compression rate was 120.1 compressions per minute (interquartile range [IQR]: 25%–75% = 117.9–133.5) for the paramedics, whereas it was 102.3 compressions per minute for the mechanical chest compression device (IQR: 25%–75% = 102.1–102.7) (P < 0.001). The median chest compression depth was 38.9 mm (IQR: 25%–75% = 32.9–45.5) for the paramedics, whereas it was 52.7 mm for the mechanical chest compression device (IQR: 25%–75% = 51.8–55.0) (P < 0.001). The median hands-off time during CPR was 6.9% (IQR: 25–75 = 5.0%–10.1%) for the paramedics and 9% for the mechanical chest compression device (IQR: 25%–75% = 8.2%–12.5%) (P = 0.09).

CONCLUSION:

During patient transport, according to the chest compression performed by the health-care professionals, it was found that those performed by the mechanical chest compression device were more suitable than that performed by the guides in terms of both speed and duration.
Prolonged cognitive dysfunction in patient with splenial lesion of the corpus callosum caused by glufosinate ammonium poisoning
Authors: Lee Hyun Jung , Kang Jeong Ho
Published: February 2021

Glufosinate ammonium (GLA) is widely used as a commercial herbicide in many countries. Neurotoxicity of GLA has been associated with serious neurological complications such as loss of consciousness, convulsions, and memory impairment. Late-onset memory impairment due to GLA-induced hippocampal lesions is the most distinct clinical feature in GLA poisoning. However, the lesion of the splenium of the corpus callosum (SCC) is a rare condition in GLA poisoning, so the clinical features are not well known. We report the case of a 57-year-old male patient who developed SCC damage after GLA poisoning. The patient had various late-onset neurotoxic symptoms, including prolonged overall cognitive dysfunction and psychosis-like symptoms. Emergency physicians should be aware that GLA-induced SCC lesions may be associated with various late-onset neurotoxic symptoms.
