Converting UML Class Diagrams into Temporal Object Relational DataBase

Number of active researchers and experts, are engaged to develop and implement new mechanism and features in time varying database management system (TVDBMS), to respond to the recommendation of modern business environment..Time-varying data management has been much taken into consideration with either the attribute or tuple time stamping schema. Our main approach here is to try to offer a better solution to all mentioned limitations of existing works in order to provide the non-procedural data definitions, queries of temporal data as complete as possible technical conversion that allow to easily realize and share all conceptual details of the UML class specifications, from conception and design point of view. This paper contributes to represent a logical design schema by UML class diagrams, which are handled by stereotypes to express a temporal object relational database with attribute timestamping

A Marketing authenticity and fair trade: toward a new relationship? Case of cooperatives in Souss Massa region

Abstract Fair trade has based on values such as trust, fairness, transparency and proximity, which are often displayed on the product’s packaging to meet the postmodern consumer’s need. This later asks for authenticity that rejoins the principles promoted by fair trade. Our paper is in line with this. It aims to explore the relationship between fair trade and authenticity through marketing approach. On the literature review’s section, we propose a state of the art on the marketing of authenticity and fair trade. Then, in the empirical section, we present a qualitative study with eight cooperatives in Souss Massa region on their practices and perceptions of this relationship. The key result is that despite the flowering of terroir products, the cooperatives display a certain ambiguity in their marketing’s manners. We advise cooperatives to consider this association: fair trade products and authenticity. Successful international trade would not always mean the marginalization of the local consumer: achieving international certification is a guarantee of quality, but satisfying local expectations is a guarantee of peripety. Keywords: marketing of authenticity, fair trade, authenticity, cooperative, Souss Mass

Pilomatricome: étude de 22 cas

Le pilomatricome est une tumeur cutanée fréquente et bénigne du follicule pileux chez l’enfant. C’est une tumeur annexielle souvent méconnue et confondue avec d’autres lésions cutanées. Les localisations habituelles sont la tête et le cou. Le but de ce travail est de rapporter une série de 22 cas comportant des formes inhabituelles colligées au service de dermatologie sur une période allant de Janvier 2006 jusqu’au Mai 2015. L’étude a concerné 16 femmes et 6 hommes. La moyenne d’âge était de 23,3 ans (4-80 ans). La localisation cervico faciale a été observée dans 12 cas, 2 patients avaient des localisations multiples, un garçon de 4ans avait une localisation au niveau fronto-temporal et une fillette de 14 ans avait une localisation au niveau du visage et de l’avant-bras,et un patient de 48 ans avait une localisation sous unguéale. L’aspect clinique était typique dans tous les cas avec des nodules sous cutanés de consistance pierreuse. Tous les patients ont bénéficié d’une exérèse des nodules sous anesthésie locale. L’étude histologique était en faveur d’un épithélioma momifié de Malherbe d’exérèse complète sans signes de malignité. Aucun patient n’a présenté de rechute. L’originalité de notre étude réside dans la présence de localisations exceptionnelles au niveau latéro-vertébral, des membres et sous-unguéale, l’âge de survenue inhabituel à 80 ans et la présence de localisations multiples signalées chez 2 enfants.Pan African Medical Journal 2016; 2

Ethanol Extract of Chinese Propolis Facilitates Functional Recovery of Locomotor Activity after Spinal Cord Injury

An ethanol extract of Chinese propolis (EECP) was given intraperitoneally to rats suffering from hemitransection of half of their spinal cord (left side) at the level of the 10th thoracic vertebra to examine the effects of the EECP on the functional recovery of locomotor activity and expression of mRNAs of inducible nitric oxide (NO) synthase (iNOS) and neurotrophic factors in the injury site. Daily administration of EECP after the spinal cord injury ameliorated the locomotor function, which effect was accompanied by a reduced lesion size. Furthermore, the EECP suppressed iNOS gene expression, thus reducing NO generation, and also increased the expression level of brain-derived neurotrophic factor and neurotrophin-3 mRNAs in the lesion site, suggesting that the EECP reduced the inflammatory and apoptotic circumstances through attenuation of iNOS mRNA expression and facilitation of mRNA expression of neurotrophins in the injured spinal cord. These results suggest that Chinese propolis may become a promising tool for wide use in the nervous system for reducing the secondary neuronal damage following primary physical injury

La temporalidad en España. Explotación estadística de los microdatos de la EPA

La temporalidad en España ha sido uno de los principales desafíos del mercado laboral. Por esta razón, es crucial realizar un análisis sobre este tema. El objetivo de este trabajo es identificar a los individuos empleados en trabajos temporales utilizando los microdatos de la Encuesta de la Población Activa (EPA) correspondientes al cuarto trimestre de 2023, analizados a través del programa estadístico SPSS. Se busca determinar qué características personales y profesionales influyen en la probabilidad de tener un contrato temporal. En primer lugar, se realiza un análisis descriptivo de los asalariados temporales. Posteriormente, se estudian las tasas de temporalidad y se identifican las variables que afectan a la probabilidad de tener un contrato temporal versus indefinido. Finalmente, se estima un modelo logit para cuantificar el impacto de estas variables en la probabilidad de tener un contrato temporal.Grado en Administración y Dirección de Empresa
