Sié Ouattara, Georges Laussane Loum, Koné Adama, Alain Clément
Int'l J. of Communications, Network and System Sciences (IJCNS) , 2011, DOI: 10.4236/ijcns.2011.411092
Abstract: The mobile communication is nowadays one of the basic needs of humanity. It is essential to the flourishing of human beings. Considering this reality, the need to use its mobile phone is become more important and diversified. The subscribers of the various mobile telephone operators are increasingly demanding. This situation poses the problems of the cover mobile network to the operators and leads them to opt for several solutions and investments. The mobile operators in order to satisfy their customers use a policy of pushing the limits of network coverage in time and space for festive moments in targeted zones. Thus, we have conducted a study on the topic: study of a kit of GSM radio site for event-driven movable coverage. This work is applied to GSM (Global system mobile) network of the operator Orange-Ci, leader of mobile telephony in Ivory Coast. We thus proceeded under investigation initially of the various aspects of the ordinary sites (motionless radio site) which are already deployed with Orange-Ci in order to impregnate us infrastructures and equipment used. This study revealed us that a radio site comprises 4 parts: infrastructures, installations and energy equipments, installations and radio equipments, and installations and equipment of transmission. After the first analysis, we made a study of the movable site. The study of the movable site enabled us to see the various possible solutions to fulfill the basic functions of a movable radio site. After analysis we retained that our radio site will be built on a truck on which a mast of 25 m maximum length for the antennas will be embarked, it will be fed by a generator also embarked on the truck and the solution of transmission selected is the transmission by satellite more precisely technology VSAT. We choose the various equipments (radio, transmission, energy) according to features which we defined to constitute the kit of movable radio site.
A New Enhanced Soil Adjusted Vegetation Index: HYBRID
Adama Ouattara,Bruce E. Frazier,Abdourahamane Konare
Online Journal of Earth Sciences , 2012,
Abstract: First-order soil brightness effects are accounted for with orthogonal indices and Soil Adjusted Vegetation Indices (SAVI) and particularly true at very low Leaf Area Indices (LAI). However, they have limited dynamic range and they fail to account for residual soil brightness effects observed at intermediate LAI. The objective of the study is to devise an index from existing ones that would overcome these shortfalls. First, a graphical method is shown to give a general formulation for the orthogonal vegetation indices (i.e., ADVI). Then, from the analysis of ADVI, it is shown that ratio and orthogonal are functionally equivalent under certain conditions. Finally, by combining ADVI and SAVI, the new hybrid index (HYBRID) obtained is the least affected by soil brightness effects at all LAI values, has the greatest dynamic range, is the most sensitive to LAI changes, saturates at very high LAI and seems to evolve linearly with LAI.

Bambara Moussa, Coulibaly Karim, Diallo Abdoul Aziz, Ouattara Adama, Zampaligré Idrissa
Open Journal of Obstetrics and Gynecology (OJOG) , 2016, DOI: 10.4236/ojog.2016.611082
Abstract: Background: The authors report cases of sexual assault reported to the obstetrics and gynecology department of the Bamako’s 5th municipality medical center during a prospective study of eight months from 1st January to 31st August 31st, 2012. Results: Twenty-one cases of assault were reported out of a total of 13,482 consultations, representing a frequency of 0%, 15%. Most victims were represented by students and accounted 43% of the study population. In 76% of cases the victims knew their assailant. The type of sexual contact was genito-genital vaginal penetration in 67% of cases and the condom was used in only one case. The average time before consultation was 3 days. The preventive ARV treatment was administered in 24% of cases and emergency contraception in 43% of cases. Conclusion: Sexual assault is common in Bamako. The reality is probably underestimated because many cases are not reported. The victims are mostly children and adolescents. The risk of transmission of STIs and HIV is very high during the sexual assault. Education and awareness of the population are essential for early consultation. Training of health workers to care for victims of sexual assault is needed.

Bambara Moussa, Konségré Valentin, Ouattara Adama, Diallo Abdoul Aziz, Zampaligré Idrissa, Lompo Olga Goumbri
Open Journal of Obstetrics and Gynecology (OJOG) , 2016, DOI: 10.4236/ojog.2016.612091
Abstract: The authors report a case of tuberculosis of the uterine cervix observed at the maternity unit of the Souro Sanon Teaching Hospital (CHUSS) of Bobo-Dioulasso. This is a rare localization of genital tuberculosis and can take the appearance of a cervical cancer. Biopsy with histological study of the lesion confirms the diagnosis. The frequency of this pathology can reach up to 8%. The extension to the endometrium and/or tubes in a young woman may compromise future fertility. Early and well conducted TB treatment allows the ad integrum restitution cervix.
Application of the Dempster-Shafer Theory to the Classification of Pixels from Aster Satellite Images and Spectral Indices  [PDF]
Jean-Claude Okaingni, Sié Ouattara, Adles Francis Kouassi, Adama Koné, Wognin Joseph Vangah, Alain Clement
Journal of Applied Mathematics and Physics (JAMP) , 2017, DOI: 10.4236/jamp.2017.57120
Abstract: In this paper, it is proposed to apply the Dempster-Shafer Theory (DST) or the theory of evidence to map vegetation, aquatic and mineral surfaces with a view to detecting potential areas of observation of outcrops of geological formations (rocks, breastplates, regolith, etc.). The proposed approach consists in aggregating information by using the DST. From pretreated Aster satellite images (geo-referencing, geometric correction and resampling at 15 m), new channels were produced by determining the spectral indices NDVI, MNDWI and NDBaI. Then, the DST formalism was modeled and generated under the MATLAB software, an image segmented into six classes including three absolute classes (E,V,M) and three classes of confusion ({E,V}, {M,V}, {E,M}). The control on the land, based on geographic coordinates of pixels of different classes on said image, has made it possible to make a concordant interpretation thereof. Our contribution lies in taking into account imperfections (inaccuracies and uncertainties) related to source information by using mass functions based on a simple support model (two focal elements: the discernment framework and the potential set of belonging of the pixel to be classified) with a normal law for the good management of these.
Etiological Aspects of the Dilatation of the Upper Urinary Tract at University Hospital of Gabriel Toure  [PDF]
Amadou Kassogué, Mamadou Tidiani Coulibaly, Zanafon Ouattara, Adama Yaflé Diarra, Aly Tembely
Open Journal of Urology (OJU) , 2018, DOI: 10.4236/oju.2018.87022
Abstract: Introduction: The dilatation of the upper urinary tract, signs in the vast majority of cases the presence of a ureteral obstacle. The etiologies are diverse. Mali is a country where urinary schistosomiasis is endemic. Repeated infestation may result in long-term ureteropelastic dilatation secondary to stenotic sequelae. The objective is to study the causes of dilatations of the upper urinary tract. Materials and Methods: This is a prospective study of 12 months, from October 2010 to September 2011, performed in the urology department of Gabriel Toure University Hospital in Bamako. The parameters studied were: age, sex, reason for consultation, medical history, urinary analysis, etiological diagnosis, management, evaluation of renal failure. Result: In 12 months, we collected 50 cases of dilatations of the upper urinary tract representing 0.66% of all consultations. The average age of our patients was 35 years old. The sex ratio was 2.13 in favor of men. A history of urinary schistosomiasis was found in 25 patients or 50%. Low back pain was the most common reason for consultation, 76%. The renal and bladder ultrasonography performed in all 50 patients in our series found bilateral dilatation in 68% of patients and unilateral dilation in 32% of cases. Urinary tract infection with Escherichia coli was found in 53% of cases. Ureterovesical reimplantation was performed in 40% of cases. Conclusion: The dilatation of the upper urinary tract, consequence of an anatomical or functional obstruction, constitutes a rather frequent pathology and constituted 10% of the surgical acts of our service. Etiologies are diverse: congenital and acquired. Open surgery gives good results, but the introduction of innovative minimally invasive surgical technique is necessary.
An Unusual Intravesical Foreign Body for Abortion Attempt. About a Case Report at Bobo Dioulasso University Teaching Hospital (Burkina Faso) and Literature Review  [PDF]
Zaré Cyprien, Kambou Timothée, Sanon B. Gustave, Ouattara Adama, Traoré I. Alain, Paré Abdoul Karim, Somé D. Adolphe
Open Journal of Urology (OJU) , 2014, DOI: 10.4236/oju.2014.44006
Abstract:

We reported a case of an intravesical foreign body in a 16 years old teenager for abortion attempt. During laparotomy for suspected pelvic appendicitis, we incidentally discovered an intravesical foreign body. From this first observation in our urology division, we reviewed the literature on the nature and circumstance of self introduction in bladder of foreign body and their surgical ablation. We emphasized the importance of endoscopy as a support of diagnosis and therapeutic of intravesical foreign body. This observation also highlighted the lack of information in our teenagers about reproductive and sexual health.

Advances in Sexual Medicine (ASM) , 2014, DOI: 10.4236/asm.2014.41001
Abstract: Objective: To study erectile dysfunction in diabetic patients seen in two clinics in the city of Bobo-Dioulasso, Burkina Faso. Materials and Methods: A prospective cross-sectional descriptive study was conducted at the Souro Sanou Teaching Hospital (CHUSS) and the Saint Leopold clinic in Bobo-Dioulasso, from March 1 to September 1, 2012. A total of 107 patients data were collated and analysed, which was then grouped into two: the ED group, designating patients with erectile dysfunction and the NED group consisting of those patients without. The sample comprised of 61 patients with types 1 and 2 diabetesand were aged between 25-70 years. The IIEF-5 was used to evaluate erectile dysfunction. Results: The prevalence of erectile dysfunction was 57%. The average age of patients was 54.4 ± 8.3 years. All patients with ED had type 2 diabetes. The mean disease duration of diabetes was 7.2 ± 6 years. Erectile dysfunction was severe in 32.8% of cases, moderate in 31.1% of cases and mild in 36.1%. Its severity was significantly associated with glycated hemoglobin, triglycerides and BMI. Phosphodiesterase types 5 (PDE5) inhibitors were found to be effective in the treatment of erectile dysfunction with a satisfactory therapeutic response in 77.4% of users. Conclusion: Erectile dysfunction is a common complication in diabetic patients. Its occurrence and severity are influenced by several factors. The potential presence of this disorder should be assessed due to its negative impact on quality of life. Phosphodiesterase type 5 inhibitors are an effective treatment modality in diabetic patients.

Abstract:

Objective: To study the epidemiology and current trend in the management of urologic complications following obstetric and gynaecologic surgeries at CUUA University hospital of Cotonou. Patients and Methods: It was a retrospective study of patients referred with urologic complications following obstetric and gynaecological surgeries. The study took place at the Teaching Clinic of Urology Andrology at CNHU of Cotonou between April 1, 2008 and March 31, 2013. Results: Forty-one patients were studied. They represented 3.5% of people hospitalized at CUUA throughout the study period. The average age was 41 years swith range of 20 and 57 years. Twenty-one (51.2%) of them were married. Thirty patients (73.2%) were referred from a non-academichospital, while 7 patients (17.1%) were referred from academic hospital. Caesarean section was the primary gynecological surgery in 22 cases (53.7%) and hysterectomy in 19 cases (46.3%). Clinically, the pre- dominant symptoms were leakage of urine throughout the vagina and obstructive anuria with or without back pain. We found 31 cases of VVF, 5 cases of bilateral ligation of the ureters, 3 cases of unilateral ligation of the ureter, 1 ureteralinjury and 1 uretero-vaginal fistula. These complications were diagnosed postoperatively in 95.1% of cases. Surgeries done included VVF repair in 31 cases (75.6%), unilateral ureteral reimplantation in 4 cases (9.8%), removal of ligation of the ureters in 3 cases (7.3%), bilateral ureteral reimplantation for 2 cases (4.9%) and end-to-end anastomosisin 1 case (2.4%). The postoperative period was uneventful in 29 cases and we observed 7 cases of surgical site infection. The overall success rate was 87.8%. Conclusion: Urological complications following gynecologic surgeries managed at the urologic department of teaching hospital of Coto-nou had an even higher incidence. Early diagnosis especially during the operative procedure would save the patients’ serious complications and open surgery due to the lack of endo-urological facilities. The most important factor in prevention is good knowledge of pelvicanatomy and good knowledge of the surgical techniques of caesarean operation section and trans-abdominal hysterectomy.

A New Vectorial Order Approach Based on the Classification of Tuples Attribute and Relative Absolute Adaptive Referent: Applications to Multicomponent Images  [PDF]

Journal of Software Engineering and Applications (JSEA) , 2017, DOI: 10.4236/jsea.2017.106030
Abstract: In this paper, we are presenting a new vector order, a solution to the open problem of the generalization of mathematical morphology to multicomponent images and multidimensional data. This approach uses the paradigm of P–order. Its primary principle consists, first in partitioning the multi-component image in the attribute space by a classification method in different numbers of classes, and then the vector attributes are ordered within each class (intra-order-class). And finally the classes themselves are ordered in turn from their barycenter (inter-class order). Thus, two attribute vectors (or colors) whatever, belonging to the vector image can be compared. Provided with this relation of order, vectors attributes of a multivariate image define a complete lattice ingredient necessary for the definition of the various morphological operators. In fact, this method creates a strong close similarity between vectors in order to move towards an order of the same principle as defined in the set of real numbers. The more the number of classes increases, the more the colors of the same class are similar and therefore the absolute adaptive referent tends to be optimal. On the other hand, the more the class number decreases or equals two, the more our approach tends towards the hybrid order developed previously. The proposed order has been implemented on different morphological operators through different multicomponent images. The fundamental robustness of our approach and that relating to noise have been tested. The results on the gradient, Laplacian and Median filter operators show the performance of our new order.
