Journal of Geoscience and Environment Protection 2019年第7期7卷 154-171页

作者： Jean-Jacques Tanoh Koua Armand Kouao Anoh drissa Tanina Soro Jean Kan Kouame Roger Jean Patrice Jourda Environment Training and Research Unit Jean Lorougnon Guédé University Daloa Cote d’Ivoire Earth Sciences and Mineral Resources Training and Research Unit Felix Houphouet Boigny University Abidjan Cote d’Ivoire University Center for Research and Application in Remote Sensing Abidjan Cote d’Ivoire

This study has used RUSLE model factors within a GIS component to evaluate eroded soil and developed viable agricultural practices scenarios to reduce soil loss in Buyo Lake catchment in the Western region of Côte d’ivoire. Consequently, five study cases were tested as following: scenario 1—association of dense forest and crops with a high percentage of mulch;scenario 2—corn and sorghum combination by considering a high yield without conventional tillage;scenario 3—establishment of an herbaceous meadow;and scenario 4—association of palm, coffee, and cocoa with green cover. Scenario P was the setting up of straw mulch after corn or sorghum harvest. The erosion map resulting from these study cases showed by estimation, an average of soil loss of about 95 t/ha/year. The respective values obtained for the scenarios 1, 2 and 3 are 28 t/ha/year, 66 t/ha/year and 30 t/ha/year. This indicates a decrease of 68%. By scenario 4, the estimated average was 2 t/ha/year corresponding to a decrease of 98%. The combination of scenario 2 with scenario P gave soil losses average of 5 t/ha/year, i.e. a 95% reduction. This study shows that the association of palm, coffee, and cocoa with green cover would be very effective in reducing soil loss.

This study focuses on the problem of access to drinking water in the fractured areas of the departments of Yamoussoukro and Toumodi. The problem has become more acute since most of the boreholes drilled have failed. The main objective of this study is to map the areas that are favorable for the installation of large boreholes in the departments of Yamoussoukro and Toumodi in order to increase the population’s drinking water needs. Hydroclimatic and cartographic data, technical surveys of boreholes and satellite images were used to conduct this study. The AHP multi-criteria analysis method was adopted. It consists in aggregating the criteria by weighting and allowed to combine these different data to generate maps of groundwater availability, accessibility and exploitability indicators. These different indicators were then considered as criteria and combined using the full aggregation technique to produce the water potential map. These results show that the study area has significant groundwater reserves with nearly 63% of these areas being favorable for the establishment of large flow boreholes. This study provides some answers to the question of groundwater resources and could be used as a decision support tool in the execution of groundwater collection works in the departments of Yamoussoukro and Toumodi in order to avoid the high percentage of drilling failures encountered in past projects.

The relationship between diabetes and periodontitis is established and described as a bidirectional influence, whereas that with dental caries is still controversial. The objective of this study was to analyze the relationship between blood glucose control and oral diseases in a population of diabetics followed at the “Centre Anti diabétique d’Abidjan” (CAdA). The dental condition of the diabetics included in this cross-sectional study was assessed by the dMF index, periodontal condition by the CPITN and oral hygiene by the OHIS index. diabetes data were extracted from CAdA patient medical records. Blood glucose control has been defined by an average of the blood glucose values of the last 3 months less than or equal to 1.26 g/l. Regression models were constructed to estimate the risk of diabetes imbalance adjusted for all characteristics collected. The sample of 356 diabetics consisted of 53.7% women with an average age of 55.6 years (range: 12 - 85 years). The average dMF index was 7.9 (Std: 6.6) with an estimated prevalence of caries of 77.0%, that of periodontitis of 53.1%. The proportion of subjects with good glycemic control was estimated at 41.3%. The characteristics associated with glycemic control were: dry mouth (p = 0.005), type of diabetes treatment (p d duration of diabetes (p = 0.039) and periodontal status assessed with the CPITN (p = 0.014). The results of this study confirmed the link between periodontitis and glycemic control of diabetes described in the literature but didn’t find significant association between dental caries and diabetes.

The biodiversity-rich primary forest of cote d’ivoire has been substantially converted into a mosaic of secondary forests, cash and lumber plantations, food crops, and timber plantations, food crops, and wasteland. deforestation started even before independence but has increased dramatically in the last three decades, resulting in the loss of most of the country’s biodiversity. It is essential to have information about the condition of the country’s natural resources following many human pressures. This research aimed to examine the cote d’ivoire Phytogeographical zones to understand the state of the wood’s ad wildlife in 2020 about the anthropic pressure on the whole Ivorian land. The Land-Use Planner approach has been used as a tool for creating a model for preserving biodiversity. There are 15 endangered tree species recognized, five each phytogeographical zone. Buffaloes are seen and distributed in the West and north of cote d’ivoire, duikers are observed in nearly all phytogeographical zones, elephants are observed in the West and North. At the same time, harnessed guibs are observed and dispersed across the nation, according to the findings. In terms of endangered tree species, the most frequent endangered trees species in the country’s south are Strombosia pustulata (6.2%), diospyros mannii (5.1%), Protomegabaria stapfiana (3.7%), Musanga cecropiodes (3.6%), and Xylopia quintasii (3.2%). In the Middle Tectona grandis accounts for (11.8%), Nesogordonia papaverifera accounts for (4.2%), Cedrela odorata accounts for (3.7%), and Gmelia Arborea accounts for (2.8%). In the North, Isoberlinia doka accounts for (10.3%), Upaca togoenisis accounts for 8.9%, Anogeisssus leicarpa accounts for (5.1%), Pterocarpus erinaceus accounts for (4.6%), and Pericopsis laxiflora accounts for (3.9%).

A study on some physico-chemical and biological variables of water quality was conducted on a coastal river in Ivory Coast. It’s the first assessment on water quality state. Those coastal rivers actually play an important role in the physical, biological and hydrological exchange between lagoons and the sea. Unfortunately, they are not taken into account by the national monitoring for water quality (RNO-CI). The samples were collected along Boubo River body through three stations, in the south of cote d’ivoire, during two years. Results show sharp fluctuations of the concentration N-NO3- nitrate, N-NH4+ ammonium and chlorophyll a with more than 20% variation. However, small fluctuations were noted for temperature, pH and conductivity with 4% - 20%. Measures are generally inferior to the threshold for hazardous water class. But respective average concentrations of N-NO3-, P-PO43-, COd and BOd5 are above natural water threshold, representing 67% of the analyzed samples of P-PO43- and 100% of the other. These results show that the river is not exempt of pollution: 0.2 mg/l of P-PO43- and 0.9 mg/l of N-NO3- are the limits of appropriate siege for the proliferation of invasive aquatic plants (IAP).

Introduction: Africans ensure their offspring by transmitting their own genes. Even if adoption is a common thing in Africa, the biological kinship keeps its supremacy. The following study tries to identify socio-cultural factors that may influence the couples’ attitude towards the gametes donation. Methods: All female patients consulting for a childbearing desire and with an indication of an assisted reproductive technique with a third donor, were included in this longitudinal retrospective and prospective study at the teaching hospital of Yopougon and in a private clinic from 1st September 2014 to 31 October 2015. 100 couples were included. Chi square test was used for statistics data. The following factors were analyzed: age, sex, religion, profession, anterior procreation, existence of a common child, infertility duration. Results: Only the age had a significant link with the egg donation refusal rate. Conclusion: This work makes it possible to foresee that Africans have the same conception of procreation because one finds this desire of childbearing in all the layers of the society.

The diabetes mellitus is a public health problem in C?te d’ivoire. The Glycemic index (GI) and the Glycemic load (GL) determination of commonly consumed foods such as juice fruits is an alternative to prevent metabolic diseases. This study carried out three wild fruits locally named Baobab (Adansonia digitata), Tomi (Tamarindus indica) and Néré (Parkia biglobosa) collected at maturity stage. The juices from the pulp of fruits have been elaborated, pasteurized, submitted to microbiological and physicochemical analysis before GIs/GLs determination. Ten healthy subjects with body mass index and age average respectively 21.57 ± 1.06 and 28 ± 2 years old tested the three juices and glucose (50 g) as reference food. Blood samples have been collected at 0, 15, 30, 45, 60, 90 and 120 min after foods consumption. The GIs/GLs has been determined according to ISO/FdI 26642:2010 protocol. data showed that pasteurized juices has a weak microbiologic load (1.0102 - 2.4102 of Mesophylls Aerobic Germs) and not contain pathogen germs. The GI and GL of Néré juice are high with respective values of 89.54 ± 1.63 and 29.22 ± 4.09 whereas those of Baobab and Tomi juice are moderate with respective GI/GL values of 66.48 ± 2.12/13.24 ± 1.99 and 60.41 ± 2.63/12.87 ± 1.67. The juice of Néré should be consumed occasionally when those of Baobab and Tomi should be consumed with moderation. It would be suitable to know more about the GI and GL of all the juice fruits produced locally so as to prevent efficiently diabetes mellitus in the country.

Introduction: Violence in hospital is a major Public Health issue. In cote d’ivoire, acts of violence against health professionals exist and may sometimes take a dramatic turn. Objective: To research the causes of this violence for the purpose to prevent them. Materials and Methods: This is a cross-sectional, descriptive study conducted in the Obstetrics & Gynecology and Pediatrics departments at the University Teaching Hospital of Bouaké from 26 January 2016 to 24 February 2016. It included 129 health workers who gave their consent. The data collection was done through individual interviews followed by a focus group according to the socio-professional category. Results: Out of 129 health professionals included, 100 were a victim of violence i.e. a frequency of 77.5%. Most of the violence occurred during “on-call hours” (55.8%) in the emergency units (34.8%). The violence was verbal (52.5%), physical (28.6%), moral and psychological (11.6%), theft (7.3%). The aggression was mainly related to patient’s care (32.1%), visiting hours (26%) and the low level of understanding of the person (16.5%). The victim’s immediate feelings were dominated by frustration (26.7%), discouragement (21.3%) and insecurity (18.3%). The victims received a medical assistance in 9% of cases. To prevent this violence, the staff mainly offered to raise awareness about violence (27.6%) and the respect for hospital staff (25%). Conclusion: Violence against health professionals is common and has negative impacts on staff and hospital activity. Its prevention requires a holistic approach centered on awareness. Keywords: Violence, Hospital, Pediatrics, Staff, cote d’ivoire.
