Background Pediatric Rheumatology (PR) is a young specialty that has not yet gained momentum in Algeria. The aim of this study is the assessment of the perception of PR by pediatric residents in Algeria and the current practice of this young sub-specialty in our country. Methods Descriptive cross-sectional study evaluating the perception of PR by pediatric residents was created on Google forms and distributed via email and Facebook to be taken as a self-administered online survey. The survey is composed of three parts: socio-demographic characteristics of the participant, current practice of PR and perspectives of PR training. Results Seventy-seven residents responded to the online questionnaire, with an average age of 30.40 ± 3.13 years and 65% of participants being female. Participation included different regions of Algeria (Batna, Annaba, Setif, Constantine, Algiers and Oran) and different levels of training (from the first year to the fifth year of residency) Ninety-two percent (92%) of participants had managed PR consultations, with a frequency of once a week in 75.3% of cases and twice a week in 15.6% of cases. In 81% of cases, it was not the initial presentation. The patients were mainly referred by a general practitioner or a general pediatrician. The Management of these patients was provided by a general pediatrician in 69.4% of cases and only in 37.7% by a specialized pediatrician. In 71.4% of cases, there was no pediatric rheumatologist in the establishment where the resident was being trained. The level of knowledge in PR was admitted to be poor by 59.7% of the respondents. Seventy-five percent of the residents wanted to have rotations dedicated to this sub-specialty during their training. Seventy percent thought that PR is equally as important to know as the other subspecialties in pediatrics (pediatric endocrinology, pediatric pneumology ...). Interest in further PR training was expressed by 80.5% of participants, given the chance. Conclusion This survey reinforces the perception that PR training needs to be improved in Algeria, especially as the number of PR consultations is on the rise. The creation of specialized training in PR is becoming a necessity.
Background Gourgerot-Sjögren syndrome (GSS) is a systemic autoimmune disease characterized by lymphocytic infiltration of the exocrine glands leading to dryness of the mucous membranes. It may also involve other organs and organ systems. GSS can be primary (pGSS) or secondary due to other autoimmune diseases. pSGS mainly affects women over 40 years old, but can occur at any age. GSS is rare in children and is often secondary to other diseases. We report the case of a 12-year-old girl with primary Gougerot-Sjögren Syndrome Methods and results A 12-year-old girl from Batna (Algeria) presented to her pediatrician in 2016 for a rash with arthralgia. She had no relevant past medical history and is the child of a non-consanguineous marriage. Clinical examination found a well-nourished child with a purpuric rash on her lower limbs. She complained of arthralgia without clinical signs of arthritis. The child also complained of a sensation of a foreign body and burning in both eyes. The eye exam was normal except for a positive Schirmer’s test. There were no signs of parotitis. Laboratory tests showed an erythrocyte sedimentation rate (ESR) of 84 mm the first h and a negative C-reactive protein (CRP). She was also Leukopenic. Serological testing resulted in a positive Anti SS-A and Anti SS-B. The abdominal pelvic ultrasound was normal. The patient was diagnosed with primary Gougerot-Sjögren Syndrome. Artificial tears and hydroxychloroquine were started as initial therapy. One year later we added an immunosuppressant (Methotrexate) due to the persistence of clinical signs. Conclusion Our case is particular in that primary Gougerot-Sjögren Syndrome is rare in children. Routine follow- up with this patient is important to determine whether it is indeed pGSS with pediatric onset or GSS secondary to another autoimmune disease.
Stratigraphic, sedimentological and magnetic study was performed on alluvial terraces, rich in archaeological tools, the region of OUM ALI, in north-eastern Algeria. The sedimentological points of view, the sediments are dominated by the sand fraction followed by the silt fraction; moderate concentrations of CaCO3 are the result of the dissolution of the surrounding limestone reliefs (Maastrichtian limestone). The morphoscopic observation of quartz grains with a dissecting microscope allows us to offer more or less significant changes, since they are often dull or sub-blunted. The results of the magnetic survey are consistent with those of the sedimentological study. The values of magnetic susceptibility are strong in the middle part of the stratigraphic section (just above the archaeological level) and decrease slightly at the top. Lower values are stored in the lower part. The dependence of frequency values of magnetic susceptibility (fd) are strong throughout the stratigraphic section and show the presence of a mixture of single-domain grain size (R), pseudo-single domain (PMD) and superparamagnetic (SP) (with a predominance of SP grains). The high concentration of SP grain size reveals the presence of significant soil formation during the implementation of the sediment
Dans cet article, l’objectif est de fournir aux chercheurs intéressés par la compétence interculturelle des pistes de réflexion sur son évaluation. Il s’agit de porter un regard analytique sur ce construit multidimensionnel tel qu’il est approché dans les différentes recherches. La clarification du concept nous permettra de dresser les modalités de son évaluation, leurs avantages ainsi que leurs limites tout en tenant compte des considérations méthodologiques garantissant leur validité et fiabilité selon le contexte de la recherche. Notre but est de dépasser une vision réductrice du concept altérant son opérationnalisation et de proposer des alternatives que le chercheur pourrait adopter.
With the huge increase of large-scale multimedia over Internet, especially images, building Content-Based Image Retrieval (CBIR) systems for large-scale images has become a big challenge. One of the drawbacks associated with CBIR is the very long execution time. In this article, we propose a fast Content-Based Image Retrieval system using Spark (CBIR-S) targeting large-scale images. Our system is composed of two steps. (i) image indexation step, in which we use MapReduce distributed model on Spark in order to speed up the indexation process. We also use a memory-centric distributed storage system, called Tachyon, to enhance the write operation (ii) image retrieving step which we speed up by using a parallel k-Nearest Neighbors (k-NN) search method based on MapReduce model implemented under Apache Spark, in addition to exploiting the cache method of spark framework. We have showed, through a wide set of experiments, the effectiveness of our approach in terms of processing time.
Un bref aperçu des confinements sporadiques - auxquels sont soumises plusieurs populations de par le monde depuis mars 2020 - supposerait des déséquilibres psycho-sociaux bien plus pernicieux et durables que la conjoncture coronavirale. Pour quelques rares personnes, cette réalité oppressive fut une aubaine : réorganiser son quotidien, apprendre une langue, exceller dans un domaine...
En ces moments de désintégration des ultimes gravats de la tour de Babel, les Fables de Jean de La Fontaine s’imposeraient certainement comme des textes salvateurs. Méfiant ou blasé des discours des hommes, Jean de la Fontaine a doté le bestiaire de paroles pleines de sagesse et de raison. Nulle cacophonie, aucune profération narcissique, pas la moindre visée trompeuse et manipulatrice, ni de jargon suprémaciste relevant de l’escroquerie et de l’imposture, les animaux de Jean de la Fontaine, sublimes personnages de ses Fables, sont indéniablement pragmatiques, authentiques, laconiques surtout et enseignent de grandes leçons morales.
Si l’humour est considéré comme un loisir populaire, voire même trivial, c’est sans doute parce qu’il est souvent spontané, incontrôlable, fortuit. Il est donc déconsidéré sur le plan artistique. Et n’est en aucun cas reconnu comme genre littéraire, tout en usant des mots et de leurs agencements. Cependant, Rabelais, Molière, Voltaire, Diderot, Queneau, et jusqu’au sublissime Frédéric Dard, alias San-Antonio, ont donné les lettres de noblesse à l’humour et à son expression. Ce troisième numéro de la série « Parenthèses » propose justement d'étudier ce rapport entre littérature et humour...

La chanson a toujours animé la société depuis les temps les plus anciens. Au-delà de la distraction et du divertissement, cet art a depuis des millénaires accompagné les hommes au gré de circonstances diverses, rythmant leurs joies, leurs péripéties et leurs peines ; officialisant ici une conquête, déplorant là-bas un deuil ; les solennités infinies qui en découlent ne manquent guère d’intérêt et confirment à elles seules l’attention grandissante que les chercheurs lui portent. Paradoxalement et malgré son importance capitale, les travaux universitaires algériens s’y rapportant se font rares. Cette journée d’étude vise à exploiter la chanson sur tous les plans, que l’on use de la linguistique, de la sémiologie, de la rhétorique, de la poétique ou de la didactique pour l’appréhender, ces disciplines peuvent aider à la comprendre, à s’en servir pour l’enseignement, ou encore, à y inclure des modalités d’analyse nouvelles au profit de la recherche scientifique.
Nowadays, we assist the global extension of reliability optimization problems from the design phase of systems and sub-systems to the design and operational phases, not only of systems and sub-systems, but also of bio functionality design. This chapter investigates the relative performances of particle swarm optimization (PSO) variants when used to find reliability in the total hip prosthesis by finding the maximization of jumping distance (JD) to avoid dislocation and the minimization of system’s stability to offer mobility. Statistical analysis of different cases of head diameters of 22, 28, 36, 40 mm has been conducted to survey the convergence and relative performances of the main PSO variants when applied to solve reliability in the total hip prosthesis.
In this study, a passive solar house prototype was built using Trombe wall and was tested in the semi-arid region of Batna, in eastern Algeria. Traditional local materials (stone and adobe) were used for the construction of the thermal storage wall. A new local bio-based material made from date palm trunks was used for the insulation of the passive house prototype. For a better understanding of passive house heating and for a comparative study, a numerical simulation, using Fluent, was carried out. The aim of this study was to supply recommendations for improving the passive systems and to participate to the energy consumption control in the building sector. The results show that the experimental and numerical simulation results are in good agreement. The optimal orientation of the solar passive house has been determined, which is at 160° southeast. The use of local and bio-based materials has proven its effectiveness in the construction of the passive house. The thermal behavior of date palm wood has been found to be close to those of insulation materials commonly used in buildings. That means it has the same thermal insulation ability (thermal conductivity). On the other hand, the results show that the thermal efficiency of the passive solar heating system, with an adobe wall is significantly higher (50%) than that with a stone wall (30.7%).
La présente contribution a pour objectif de déterminer la place de l’écrit par rapport à l’oral dans le système éducatif algérien ainsi que de rendre compte de la manière dont la pédagogie du projet permet le développement des compétences de compréhension et de production de l’écrit. Pour ce faire, nous avons pris les programmes du cycle moyen du système éducatif algérien comme objet d’étude. Dans un premier temps, nous avons analysé les programmes, manuels scolaires, et guides des professeurs, dans le but de déterminer l’importance accordée par les instances éducatives aux deux compétences (écrit, oral). Nous avons expliqué, dans un second temps, à travers la présentation d’un exemple de projet comment la pédagogie du projet permet-elle un meilleur développement de la compétence de l’écrit.
