    Challenges And Effect Of Implementing Enterprise Resource Planning (ERP) On Organizational Performance (A Case Study At Ethiopian Agricultural Transformation Agency)
    (Addis Ababa University, 2019-06) Solomon, Feven; Ensermu, Matiwos (PhD)
    Enterprise Resource Planning (ERP) is a process of managing all resources of an enterprise in a coordinated manner. The system is considered as a powerful weapon to optimize performance of the organization. The objective of this study was to analyze the challenges in implementing ERP system and its’s effect on organizational performance of the Agricultural Transformation Agency (ATA) in Ethiopia. Analysis of effect of ERP implementation on Performance require determination of major components; Quality Management, Financial Management, Customer relationship Management, Inventory management, Procure ment management, Logistics management and Human Resource Management. The problems of, longer lead and cycle times, high implementation costs, user resistance, lack of training and incentives, high inventory level, in ERP implementation were the critical factors that initiated this study for investigation. Both descriptive and an explanatory research design was employed with a sample of 184 employees through Sample survey that was 92% of the response rate. A questionnaire was used as a research tool for collecting data. Available data on these factors was gathered, formatted, processed and thoroughly checked for continuity and consistency. The ERP implementation and organizational performance data were infilled using the Five Point Likert-Scale while the Cronbach Alpha was used to check the data for reliability of measurement scale. The relationship between independent variables (ERP Adoption) and dependent variables (organizational Performance) are also cross-checked from Pearson correlation matrix. To predict organizational performance from ERP Adoption dimensions, such Quality Management, Financial Management, Customer relationship Management, Inventory management, procure ment management, Logistics management and Human Resource Management, the multiple linear regression model was adopted. The analysis indicated that the independent variables, ERP Adoption with respect to the seven dimensions (Quality Management, Financial Management, Customer relationshipManagement, Inventory management, procure ment management, Logistics management and Human Resource Manage-ment) explained 44 % variance on organizational performance. Out of the seven independent var-iables, five of them (Procurement management, financial management, customer relationship management Quality management and logistics management ) were statistical significant with p-value of less than 0.05 whereas the remaining two (Inventory management, and Human Resource Management) were statistical insignificant with p-value greater than.05.; this implies that these dimensions of ERP Implementation are not at the optimal level in the organization. It is recommended that all the seven dimensions of ERP implementation (Quality Management Financial Management, Customer relationship Management, Inventory management, procure ment management, Logistics management and Human Resource Management) should have to be integrated at the optimal level through system automation, framework agreement and relationship management in order to be an efficient and effective organizational performance

    Cost effectiveness analysis of cervical cancer screening methods at family guidance association, Addis Ababa,Ethiopia 2017
    (2018-10) Solomon, Feven; Hailemariam, Damen (Professor,MD, MPH, PhD)
    Background: Cervical cancer is one of the most widespread and second leading cause of gynecological related mortality worldwide. In developing countries, the number of deaths and morbidities from the disease has been on the rise. Cervical cancer is usually detected in advanced stages in these countries due to the lack of effective preventive mechanisms. In Ethiopia only 1% of age eligible women receive effective screening for cervical cancer. Although organized cervical cancer screening has been proven to be effective in saving significant number of lives in developed world, there are a number of barriers to expand them into developing world such as competing health care needs, limited human and financial resources, poorly developed health care services, gender related barriers, political instability and widespread poverty. Objectives: To evaluate the cost-effectiveness of cervical cancer screening methods, Addis Ababa, Ethiopia. Methods: Institutional based cross sectional study design was used. The cost was from societal perspective. Sample size was determined using singe population mean formula and systematic random sampling techniques was used to include women for the interview and also the cost from provider perspective were collected from the three clinics. Full economics evaluation was done using Markova model to construct and simulate the natural history of HPV-induced cervical dysplasia to compare cost and effectiveness of Papanicolaou, Visual Inspection of cervix with Acetic acid and Human Papilloma virus Deoxyribonucleic Acid test. A micro-costing approach was used to measure and aggregate the cost of all resources used to provide cervical cancer screening at individual level. Cost-effectiveness analysis was used to determine the incremental cost-effectiveness ratio. Results: Cost of VIA, PAP and HPV DNA test from societal perspective was found to be $14.23, $ 20.51and $19.06 respectively. Among the three screening strategies, Pap smear was not cost effective at any given willingness to pay threshold. VIA and HPV DNA test was cost effective at incremental cost effectiveness ratio $ 268.10 per disability adjusted life year averted. Conclusion: Cervical cancer screening using VIA and HPV DNA test are cost-effective strategies.

    Spatial and temporal water quality trend analysis using sediment cores and water samples from Aba Samuel Lake, south west of Addis Ababa, central Ethiopia
    (Addis Ababa Universty, 2007-07) Solomon, Feven; Umer, Mohammed (PhD)
    The first objective of this work is to assess the temporal variation of Cu, Zn, Pb, Cd, Cr and Ni in sediments of the Aba Samuel Reservoir Lake, south west of Addis Ababa. Two sediment cores with 44 and 49 cm length were recovered at the proximity of the dam in the south (Core 1) and at the western shore (Core 2). Sediment slices have been taken from top, middle and bottom parts of the cores for analysis. Sedimentation rate was estimated using constant rate and therefore by linear extrapolation using the age of the dam as a base line (68 yrs). Considering 4m average depth of sediment over the span of time the dam construction took, an average sedimentation rate of 6cm/yr has been calculated. The core bottom sediments contain therefore the history over the last 7 years. The result of the analyzed heavy metals shows a general increasing trend from the bottom to the top samples in the cores. The amounts currently obtained, except for Nickel and copper, are still below the standard value. However, the value of all analyzed metals will be higher than the standard if the current concentration is to be projected towards the next 7 years. Nickel concentration is higher than the standard value for both sediment cores. Comparing the concentrations in the respective sediment cores, sediment core 2 has an average value of 51.4 mg/kg and sediment core 1 contains 42.5 mg/kg on average. This shows the slight spatial variation within the lake. The variation could be due to differential trapping along the path of the water and the closeness of sediment core 2 to the inlet point of the lake than sediment core 1. Nutrient analyses have been conducted for the lake water. Nitrate and phosphate show decreasing trends from the inlet towards the outlet of the lake; this could be due to the uptake of these nutrients by water hyacinth and the settlement of nutrients along with sediments. While, ammonia increases from the inlet to the outlet, possibly owing to the prevalence of a reducing environment which results in the formation of ammonia. From this study it was possible to observe that, the pollution load in the Aba Samuel Lake is increasing. This confirms the importance of anthropogenic load becoming important in the background of possible constant natural supply. Therefore, proper monitoring of pollutants in the lake environment is crucial.
