    Investigating the Strength Characteristics of Laterittic Soil Blended with Marble Dust
    (Addis Ababa University, 2016-11) Assefa, Blen; Tadesse, Samuel (PhD)
    The purpose of this study is to investigate the strength characteristics of a stabilized lateritic soil with marble dust. The sample of the residual lateritic soil used in the study is taken from Mekanejo area. The soil is classified as A-7-5 according to AASHTO classification. The material could possibly termed true laterite, since silica-sesquioxide ratio is Less than 1.33. An attempt has been made in the study to improve the index and engineering properties of the lateritic soil by stabilization using an industrial waste, marble-dust. This method is both low-cost and ecofriendly. Accordingly, the lateritic soil was treated with marble-dust of 4%, 8%, 12%, 16% and 20% by dry weight of soil, and various tests have been carried out on the marble-stabilized soil to assess alterations in its strength characteristics. The lateritic soil responded very well to the marble-dust treatment, as exhibited in improvement of its strength, and its increased resistance to softening by water. 20% marble dust is the optimum quantity in terms of improving plasticity index, maximum dry density and soaked and unsoaked CBR properties but for unconfined compressive value, the optimum marble dust content is 8%. The addition of marble-dust to the lateritic soil has beneficial effects on its engineering properties, including reduction in plasticity, improved workability, increased strength, more resistance to moisture effect, and enhanced durability. Besides, a trial pavement design revealed that lateritic subgrade stabilization results in thinner pavement structures, and hence reduces costs of road construction

    Maternal Satisfaction with Delivery Services of Public Health Centers in Addis Ababa, Ethiopia, 2017 Gc
    (Addis Ababa University, 2017-06) Assefa, Blen; Cherie, Amsale (PhD)
    Background:Accessibility of maternal services alone cannot guarantee usage by womenneither does the use of maternal health services guarantee optimal out comes for women.Maternal satisfaction with delivery services affects selection of birthplaces, helps to identify gaps between the actual health care and the desired health care outcomes and assists policy makers in developing interventions based on findings. Objective:The aim of the study was to assess the level of maternal satisfaction with delivery services and identify factors affecting the level of maternal satisfaction in public health centers of Addis Ababa, Ethiopia, 2017 GC. Methods:Institution based cross sectional quantitative and qualitative study was conducted from April12 to May 20, 2017. Multi stage sampling method was used to select 461 mothers from 20 health centers. Interviews using a structured questionnaire wereused to collect the quantitative data. And data was entered using Epi –info 7 and analyzed using SPSS version 20. Bivariate and multivariate logistic regressions were applied at 95% CI.For the qualitative part of the study, in depth interviews were used for data collection and thematic analysis was used to generate themes. Result:This study’s finding indicated an overall maternal satisfaction level of 82%. Women who were satisfied by respectfulness of the staff were 8.7 times more satisfied with the overall services than those who weren’t AOR(95%CI) 8.712(2.171,34.961). Mothers who received cognitive care were 18.6 times more satisfied than those who didn’t AOR(95%CI) 18.611(2.658,30.294). Mothers who were satisfied with the sex of the health workers who attended their deliveries were 10.7 times more satisfied than those who weren’t AOR(95%CI) 10.742(3.218,35.866).Mothers who felt like their babies received adequate care were 38.8 times more satisfied than those who didn’t. Conclusion: Cognitive care, competency, respectfulness, neonatal care and satisfaction with the sex of health workers were important predictors of maternal satisfaction. Recommendation:Addis Ababa city administration health bureau, health facility managers and health workers should work together on identified factors to improve maternal satisfaction. Key words: Maternal satisfaction, delivery services, public health center
