Most African countries including Senegal face a deficit of doctors. This paper presents a new architecture at lower cost allowing the use of Access Point to pass the data from biosensors to the collects used in the field of medicine. The paper proposes a new QoS management prototype to put as priority traffic from biosensors at the expense of traffic from other types of clients in order to receive in real time physiological data collected from the patients. © 2016 IEEE.

This article discloses a system for locating mobile nodes and transfer data in a mobile learning system. The proposed solution is based on organizing cell cellular networks and the geographical coordinates. This means that mobile nodes are located thanks to their geographical position, which allows grouping the nearest nodes in a cell which we call Node Open Digital Space (NODS). In order to better organize the mobile learning system is a server placed at each Open Digital Space (ODS) allowing access to resources. These servers at each ODS are connected to a central server that centralizes all the data to identify the mobile nodes. This hierarchical architecture meets the needs of collaboration and latency reduction in a mobile learning solution that we want to implement in Senegal. © 2016 IEEE.

Frequent Itemsets Mining (FIM) is an essential data mining task, with many real world applications such as market basket analysis, outlier detection, and so one. Many efficient single-node FIM algorithms such as the well-known FP-Growth algorithm have been proposed in the last two decades. However, as large-scale datasets are usually adopted nowadays, these algorithms become inefficient to mine frequent itemsets over big data. Scalable parallel algorithms hold the key to solving the problem in this context. However, the existing parallel versions of FP-Growth algorithm implemented with the disk-based MapReduce model are not efficient enough for iterative computation. In this paper, we propose an implementation of scalable parallel FP-Growth using the inmemory parallel computing framework Apache Spark™. Our experimental results demonstrated that the proposed algorithm can scale well and efficiently process large datasets. © 2017 IEEE.

In 2006, the Senegalese government introduced the "Plan Sésame", an unprecedented policy in West Africa aimed at reducing social vulnerability among the elderly (i.e. people aged over 60 years). This paper examines the process of implementation of the "Plan Sésame". Using a qualitative approach, the study was based on a unique case study authorized by the Senegalese Ministry of Health. Three methods were used: i) individual interviews (n = 19), ii) discussion groups (n = 24), and iii) documentary study. Despite its social objective, the "Plan Sésame" was ultimately limited to free health care. However, even the health component of the plan has suffered from underfunding. Political obstacles, inadequate accompanying measures and short staffing have resulted in late reimbursements at a local level, thus limiting the implementation of the plan. While both health professionals and elderly people are in favor of free healthcare, they are also critical of the implementation issues surrounding the "Plan Sésame". Although it appears to be a viable solution, these issues may spell the end of the plan. The task of designing solid technical foundations and developing appropriate accompanying measures should not be overlooked because of the limited interest of international partners in the "Plan Sésame", the national dimension of the plan and its electoral importance.

In Senegal, great amounts of data are daily generated by medical activities such as consultation, hospitalization, blood test, x-ray, birth, death, etc. These data are still recorded in register, printed images, audios and movies which are manually processed. However, some medical organizations have their own software for non-standardized patient record management, appointment, wages, etc. without any possibility of sharing these data or communicating with other medical structures. This leads to lots of limitations in reusing or sharing these data because of their possible structural and semantic heterogeneity. To overcome these problems we have proposed a National Medical Information System for Senegal (SIMENS). As an integrated platform, SIMENS provides an EHR system that supports healthcare activities, a mobile version and a web portal. The SIMENS architecture proposes also a data and application integration services for supporting interoperability and decision making.

Erectile dysfunction (ED) is often a reason for consultation revealing the existence of cardiovascular risk factors. The objective of this study was to determine the cardiovascular risk factors associated with ED in the Dakar region.A descriptive and analytical cross-sectional study was conducted from March 18 to June 2, 2013. The study population was composed of married male subjects who sought care at the Ouakam Geriatric and Gerontology Center and the Grand Yoff General Hospital. Erectile function was assessed with the International Index of Erectile Function using the simplified five-item questionnaire (IIEF 5). R 2.2.9 software was used for the logistic regression multivariate analysis. Associations were measured using the adjusted odds ratio (ORaj) with confidence intervals.A total of 253 men were surveyed during this period. Average age was 16.758.2 years, range 24-90 years; 47% were aged under 60 years. ED was diagnosed in 110 patients (43.5%). ED was considered mild (33.6%), moderate (5.5%) or severe (4.3%). ED was more severe in patients older than 60 years. Cardiovascular risk factors associated with ED were diabetes ORaj=2.4 (1.24-4.68), sedentary lifestyle ORaj=3.08 (1.69-5.61), and hypertension ORaj=2.53 (1.33-4.81).These results should prompt health care providers to target patients with diabetes, hypertension and sedentary lifestyle for systematic ED screening as a routine practice in order to ensure early and effective care.

In Senegal, due to the young age of the population (60%) the concerns of the old tend to be put in the background. And yet, problems related to old age are a reality. These problems come up not in terms of demography (the old represent only 4.7% of the population), but in terms of the breaking-up of the social fabric, urbanization and the dismantling of the solidarity and poverty networks. This work is based on a collection of qualitative data from three studies conducted between 2008 and 2011 with the elderly to assess their real- life experiences, their perception of aging, their challenges and coping strategies. The results showed a transformation in the role and status of the old; this transformation being caused by social and society-related mutations. As a result, the inter-generation solidarity links have much loosened in the urban areas making the old people more vulnerable (in economic, social, health terms), especially those in charge of a family. The situation has been made worse by the unemployment affecting their offspring. In addition, the old people, who are often suffering from chronic diseases, find it hard to take charge of their medical expenses, despite the institution of the National Sesame Health Plan for the old or free health care policy. This has made them even more vulnerable. Yet before this precarious situation, the elderly develop strategies to cope with difficulties. Some recommendations have been made with a view to improving their lives and socioeconomic condition.

In 2005, Juels and Weis proposed HB+, a perfectly adapted authentication protocol for resource-constrained devices such as RFID tags. The HB+ protocol is based on the Learning Parity with Noise (LPN) problem and is proven secure against active adversaries. Since a man-in-the-middle attack on HB+ due to Gilbert et al. was published, many proposals have been made to improve the HB+ protocol. But none of these was formally proven secure against general man-in-the-middle adversaries. In this paper we present a solution to make the HB+ protocol resistant to general man-in-the-middle adversaries without exceeding the computational and storage capabilities of the RFID tag. © Copyright 2015 SCITEPRESS - Science and Technology Publications.

The bites of the venomous snakes constitute a medical, social and economic problem for the African, low-income rural populations and remote from health centers. The relatively high cost of the antivenomous serotherapy makes this treatment, today even, inaccessible to a major or to the quasi-totality of the African population. In Senegal, most of 8000 persons are bitten every year by a snake among which approximately 150-200 die from the consequences of these bites, mainly at the beginning and at the end of agricultural period. The use of extracts of plants with therapeutic aim is a current practice in African traditional medicine. The study was conducted between October, 2010 and January, 2011 and consisted in conducting a survey in three sites in three regions of Senegal: Dakar, Kaolack, and Kédougou, which were chosen on the basis of their accessibility and their important attendance rate by the patients presenting snake bites. The survey was conducted by means of questionnaires with intended opened answers, with tradipraticiens and chemists. Two families of plants were found to be used as well by the quack's and tradipraticiens than by the chemists. These families are all of the shru: (1) Annonaceae (four species): Anonna chrysophylla Boj., A. senegalensis the var. (Boj.) chrysophylla R. Sillans, the var latifolia Oliv. A. senegalensis, A. arenaria thonn; (2) Poligalaceae (one species): Securidaca longepedunculata. © 2011 Elsevier Masson SAS. All rights reserved.

The management of the data is an important aspect in the quality and the performance of the information system in higher education. It allows to do research from the collected data and especially to follow daily the learners in the progress of their learning activities (apprenticeship). By studying and by analyzing the evolution in Senegal of the increasing number of students from 2012 till 2015 and by being based on the results and the statistics supplied by the World Bank from 1971 till 2011 in terms of registration in higher education, a project was introduced for the implementation of an on-line environment of collection, treatment and data analysis. In our communication, a work was made within the framework of the searches on the learning platforms. This study is based on a sample of 6684 learners from three education structures. All this has allowed to confirm the studies and the analyses produced and published in the form of indicators of world development in the category of the education in Senegal. This article shows how the functional analysis of the platform LMDPRO is made to lead to interfaces allowing to collect, to handle and to analyze gross data for the improvement of the quality of the information for indicators in higher education. © 2015 IEEE.
