Item Application of Multi-criteria Decision Model and GIS for Criterion Weight Estimation(Department of Geography and Environmental Management, University of Ilorin., 2021) Babalola, A.This paper presents the application of Geographic Information Systems (GIS) and Multi-criteria analysis techniques for criteria weight estimation in an environmental decision making process. The location or siting of landfill in environmental management is based on certain factors or criteria. Criteria such as land use, slope, soil, rainfall, and distance to road, aspects, and groundwater and water body are considered here. The relative importance weightings of the criteria are determined using super decision software.Item Application of Spatial Analysis Approach for the Siting of MSW Landfills(Department of Geography and Environmental Management, University of Ilorin., 2021) Babalola, A.A spatial methodology which involves geographic information systems, spatial analysis and spatial statistics is presented. The aim of this methodology is to evaluate the suitability of the study area in order to site municipal solid waste (MSW) landfills. The methodology uses spatial analysis techniques to establish the criteria for evaluation, which are based on local legislation. Several; factors are used in the siting process including agricultural areas, aspect, commercial areas, educational areas, residential areas, road distance, sensitive sites, and water body. Adopting the simple additive approach, the suitability of the study area for landfill siting is evaluated. The final land suitability index report is on a grading scale of 0-5, which is from least suitable to most suitable land areas for landfill site in order to address the waste management problem.Item APPLICATIONS OF GEOGRAPHIC INFORMATION SYSTEM AND THE THEORY OF EVIDENCE FOR WASTE DISPOSAL SITE SELECTION(Department of Geography, Nassarawa State University, Keffi, 2017) Babalola, A.The increase in population and improved life style have led to the growth in the amount of municipal solid waste generation the world over, and the need to identify or locate suitable place (s) for these wastes to be dumped has also increased tremendously. This paper provides an overview of the theory of evidence and its applications to solid waste management. The theory of evidence particularly, Bayesian probability and the Dempster-Shafer theory (DST) approaches has emerged and has found favour in many types of applications such as signal detection, image classification, and sensor fusion. Here the DST approach is used to identify suitable sites for landfill in Damaturu. The DST method shows promise for the identification or location of sites for Waste managementItem DECISION MAKING IN SURVEYING AND GEOINFORMATICS(Faculty of Environmental Sciences, University of Ilorin Kwara State Nigeria, 2019) Babalola, A.; Ipadeola, A.O.; Issa, B.S.One of the most important decisions that a surveyor has to make before embarking on a given surveying project is the selection of the instrument. Where there are number of choices, a decision by way of selection has to be made. The selection can be based on a number of criteria, for instance, accuracy, cost, user friendly, size of project, user knowledge and experience, project type and duration. The need to have the best equipment for the right job cannot be overemphasized. This requires that the surveyor should select the equipment to be used in an objective way, taking into cognizance all factors and their priorities. The aim of this paper is to demonstrate the use of the Analytical Hierarchy Process (AHP) as a form of decision-making methodology in the selection of equipment for a surveying project. Priority weights for each factor controlling the choice are also determined. 3 instruments were considered for selection – Total station, DGPS and theodolite and 7 elements used in the instrument selection - accuracy, cost, user friendly, size of project, experience/ knowledge, project type and duration. The accuracy of the equipment appears to be the element with the highest importance. While experience and knowledge accounted for the next element on the level of importance. The element with the least importance user friendly element.Item DESIGN AND IMPLEMENTATION OF SUSTAINABLE BUILT ENVIRONMENT: THE ROLE OF SURVEYING AND GEOINFORMATICS TOWARDS EFFECTIVE COLLABORATION WITH OTHER PROFESSIONALS(Faculty of Environmental Sciences, University of Ilorin, 2019-04) Ahmadu, H. A; Babalola, A.; Salami, B. I.Built environment sustainability has become an issue of national concern, owing to the constant threat posed by its negative impacts on the survival of man. This has made it necessary for a study on how there can be collaboration for sustainable development in the built environment, in order to reduce or completely eliminate its negative impacts (such as climate change, environmental degradation, desert encroachment, etc.). This paper proposes the identification of the role of professionals in the design and implementation of built environment, as a means of enhancing effective collaboration for sustainable development in the built environment. The roles of Surveying and Geo-informatics in design and implementation stage of the built environment were investigated through a review of literature, after which a research questionnaire was issued to professionals in the built environment to seek their assessment on how each role could serve as a collaborative support towards achieving sustainable development in the built environment. Descriptive statistics (mean score) was used to analyze and gain an overview of the data obtained. The results showed that all the roles of Surveying and Geo-informatics at the design and implementation stage of built environment would support and enhance effective collaboration for sustainable development in the built environment.Item Knowledge, Awareness and Prevalence of Viral hepatitis Among Health Care workers (HCWs) of the Federal Medical Centre Bida, Nigeria(Department of Heamatology and Blood Transfusion, Federal Medical Centre, Bida, Nigeria, 2017-06) Awimero, C. E.; Nelson, E. A.; Yusuf, M.; Olaosebikan, O. F.; Adeboye, M. A. N.; Adamu, U. G.; Oladele, C.; Busuyi, J. S.; Erinle, S. A.; Babalola, A.Background: The health care workers (HCWs) hitherto are considered to be one of the vulnerable groups when compared to the general population due to the nature of their day-to-day workplace activities. However, in spite of the high seroprevalence level nationally, the level of awareness and knowledge about viral hepatitis amongst the general populace including the public health workers is non –uniform. Aims and Objective: To determine the knowledge, awareness and prevalence of viral hepatitis as well as to raise awareness among HCWs. Study design: cross sectional survey. Setting: Federal Medical Centre, Bida Niger State, Nigeria. Materials and Methods: A structured questionnaire was administered to Two Hundred and forty eight HCWs of the Federal Medical Centre, Bida. Blood samples were collected from individual participants and screened for Hepatitis B surface Antigen (HBsAg), Antibody to Hepatitis C Virus and Antibody to Hepatitis B core antigen using rapid ELIZA technique. Statistics: Data analysis was performed using SPSS version 20 software to obtain descriptive statistics for all participants with respect to demographic distribution, prevalence rate for HBV and HCV. Chi-square test was used to obtain relations between various categorical data. The statistical significance of the data was based on a p-value of ≤ 0.05 at the Yates’ continuity correction line. Results: Of the two hundred and forty eight participants, 41.1% were males and 58.9% were females, M: F 1:1.4. The mean age was 33.7 (SD 6.9) years (range 20 - 54yrs). Occupational distribution was based on four main categories of health care workers; Doctors, Nurses, Allied health workers (AHWs) and Admin Staffs with frequency of 23(9.3%), 52(21.0%), 100(40.3%) and 73(29.4%) respectively. With regards to the educational level of the participants, 20(8.1%) were in the category of lower level education, 58 (23.4%) had middle level of education and 170(68.5%) were highly educated. The overall seroprevalence of hepatitis among the health care workers (HCWs) were as follows: HBsAg (11.3%), HCV (2.4%) and HBcore antibody (46.0%). Overall Awareness of the various types of hepatitis was 70.6% with a marked trend over educational levels. Conclusion: This study provided prevalence data, relevant information on the magnitude of disease burden and the significance of education on awareness of hepatitis B and C in this settings. There is paucity of awareness and knowledge among certain category of HCWs. Therefore concern Authorities should provide more HBV / HCV interventional information impact measures to raise awareness and knowledge among this group. Policies and guidelines of critical preventive protocol to ensure safety in a workplace environment including pre and post-exposure vaccination intervention for HBV to the staff should be in place.Item Unusual Presentations of Multiple Myeloma: Case Report And Review With Focus On Therapeutic And Psychological Aspects(Internet Scientific Publications, 2006) Agaja, S.; Babalola, A.; Olawumi, H.; Babatunde, A.Background: Unusual presentations of multiple myeloma which poses a diagnostic dilemma. Objective: To report unusual presentations of multiple myeloma and highlight how early detection of these unusual features will encourage early investigation, diagnosis and appropriate management and consequently better prognosis of this difficult disease of multiple myeloma. Patients and Methods: Two cases of multiple myeloma initially managed at Ela Memorial Medical Centre, Ilorin, were presented. The clinical features, management and outcome were extracted from the case notes. After operations on the patients the histological specimens were sent to University of Ilorin Teaching Hospital (U.I.T.H.). The patients were later transferred to UITH for further management. Results: The first case report presented with multiple swellings on the right shoulder, left chest wall, and back and weight loss. X-ray showed fracture of the left clavicle. The erythrocyte sedimentation rate was normal. Bence-Jones Protein was positive and histological report and Bone Marrow aspiration cytology confirmed multiple myeloma. The second case report presented with inability to use the right upper limb and later developed severe pain on the right shoulder and weakness of the right upper limb. X-ray showed fracture of the upper third of the right humerus. Erythrocyte sedimentation rate was very high and Bence-Jones protein was negative. Histological report was suggestive of multiple myeloma whilst bone marrow aspiration confirmed multiple myeloma. The first case was lost to follow up whilst the second case died during chemotherapy. Conclusion: Presence of multiple swellings on the body and pathological fractures should suggest that such patients should be investigated for multiple myeloma. Failure to start the investigations will lead to delayed diagnosis, delayed management and very poor prognosis.
