  • Integration of Multi Criteria Analysis Methods to a Spatio Temporal Decision Support System for Epidemiological Monitoring
    Integration of Multi Criteria Analysis ICAASE'2014 Methods to a Spatio Temporal Decision Support System for Epidemiological Monitoring Integration of Multi Criteria Analysis Methods to a Spatio Temporal Decision Support System for Epidemiological Monitoring Farah Amina Zemri Djamila Hamdadou LIO Laboratory LIO Laboratory BP 1524 EL M’ Naouer, Oran University, Algeria BP 1524 EL M’ Naouer, Oran University, Algeria [email protected] [email protected] Abstract – The present study aims to integrate Multi Criteria Analysis Methods (MCAM) to a decision support system based on SOLAP technology, modeled and implemented in other work. The current research evaluates on the one part the benefits of SOLAP in detection and location of epidemics outbreaks and discovers on another part the advantages of multi criteria analysis methods in the assessment of health risk threatening the populations in the presence of the risk (presence of infectious cases) and the vulnerability of the population (density, socio-economic level, Habitat Type, climate...) all that, in one coherent and transparent integrated decision-making platform. We seek to provide further explanation of the real factors responsible for the spread of epidemics and its emergence or reemergence. In the end, our study will lead to the automatic generation of a risk map which gives a classification of epidemics outbreaks to facilitate intervention in order of priority. Keywords – Multi criteria Analysis Decision Support (MCAM), Spatial Data Mining (SDM), Spatial on Line Analysis Processing (SOLAP), Data warehouse (DW), Epidemiological Surveillance (SE). devoted to the PROMETHEE method tool used for the development of multi criteria decision 1.

  • La Couverture Sanitaire De La Wilaya D'oran
    La couverture sanitaire de la wilaya d’Oran Pr. Larbi ABID La wilaya d'Oran est située au nord-ouest du pays. Peuplée de 1 734 133 habitants en 2014 pour une superficie de 2 114 km2, elle est bordée à l'est par la wilaya de Mostaganem, au sud-est par celle de Mascara, au sud-ouest par celle de Sidi Bel Abbes et à l'ouest par celle d’Ain Témouchent. Le relief de la wilaya d’Oran est présenté selon six composantes naturelles : • La bordure côtière où on distingue les côtes rocheuses s’étalant des monts d’Arzew jusqu’à Mers El Kebir à l’Ouest et du Cap Lindles jusqu’à Cap Sigal, limite administrative de la wilaya ; les plages sableuses de la basse plaine de Bousfer-les Andalouses et de la baie d’Arzew. • Les collines du Sahel constituées par les monts d’Arzew : Ensemble de hautes collines bordant toutes les falaises abruptes allant d’Arzew à Canastel (Est d’Oran) et le Murdjadjo et ses prolongements à l’Ouest. • La basse plaine littoral de Bousfer-Les Andalouses, ensemble pénéplaine déclinant vers le Nord, très abrité par les collines sahéliennes disposées en amphithéâtre. Un seul cours d’eau important draine cette basse plaine à l’Ouest, l’oued Sidi Hammadi près du complexe touristique des Andalouses. • Le plateau d’Oran-Gdyel, s’étendant sur une vaste superficie, des piémonts du Murdjadjo, jusqu’au Sahel d’Arzew. Ce plateau est marqué par une absence de drainage et de nombreuses dépressions plus ou moins salées : la grande Sebkha d’Oran qui marque la limite du Plateau à l’Ouest, la Daya Morsli, le lac Télamine, les Salines d’Arzew limite du plateau à l’Est.

Pour cela, deux images spatiales ont été utilisées issues des satellites LANDSAT datant respectivement de 1987 et 2016 ainsi des cartes topographiques de 1987. Les résultats obtenues sont discutés et comparés à l’étude de l’évolution démo- graphique sur les quatre derniers recensements de RGHP (Recensement général de la population et de l’habitat). Les résultats ont montré que le phénomène de la saturation des principales villes du littoral ouest oranais (Oran, Ain El Turck) a été accompagné d’un coté de la croissance démographique importante, et d’un autre côté de la réalisation des nouvelles zones d’habitat urbain planifié intense.

    Plant Archives Volume 20 No.2, 2020 pp. 4627-4632 e-ISSN:2581-6063 (online), ISSN:0972-5210 MINERAL BALANCE OF AN INVASIVE ALGA CAULERPA RACEMOSA VAR. CYLINDRACEA ON THE COAST WEST OF ALGERIA Ghellai Malika 1*, Bachir Bouiadjra Benabdallah1, Bachir Bouiadjra Mohammed El Amine2, Sahih Faouzia2 and Mahmoudi Kenza2 1*Laboratory of Science and Technic of animal Production (LSTPA), University of Mostaganem (UMAB), Algeria. 2University Center of Relizane, Algeria. Abstract Our study was based on the demonstration of the water contents, of Chlorophylls a, Chlorophyll b, and Carotenoids, and of the mineral elements Na+, K+, Mg2+, Ca2+, in the thalli of the invasive alga Caulerpa racemosa var cylindracea harvested in eight stations located on the west coast of Algeria positioned on the Wilaya of AIN TEMOUCHANT; Sbiaat, the wilaya of ORAN; Bousfer, Kristel, Arzew, Mers el hadjadj, and the wilaya of MOSTAGANEM; Stidia, Salamander and Grove. The results obtained indicate a high water content for our thalli and high pigments contents compared for the stations studied, and significant contents in nutrients Na, Mg for the thalli from the different study sites marking a lack of element K by Na ratio by studying the Na / K ratio and a Ca level which is within the norms, which leads us to conclude that our species is rich in essential elements for its well being. Key word s: Caulerpa racemosa Var cylindracea, mineral elements, Chlorophyll a, Chlorophyll b, Carotenoids, Algeria. Introduction looking at the spread of this invasive species on the Algae are unicellular or multicellular eukaryotic Algerian coast. Our study is based on the identification organisms (Pereira & Neto 2015), presenting a great of the content of chlorophylls a, b and carotenoids, and a 2+ 2+ + diversity (Stengel & Connan 2015), according to their study on the content of mineral elements Mg , Ca , K , + size, they can be divided into microalgae and macroalgae, and Na which are necessary for the food and the well which also include green, brown and red algae according being of this species.
