W Melese, T Tadesse, W Asefa
Ethiopian Journal of Education and Sciences , 2009,
Abstract: This article explores the practice of learner-centered methodology in upper primary school of Ethiopia and the major obstacles for the effective use of such methods in the classroom. Data were collected from upper primary school teachers, school principals, and students through observation, interview and focus group discussion from the sample schools in the country. The results of the study revealed that even though it is not adequate, upper primary school teachers try to employee learner centered methodology in the classroom. The major hindering factors identified for effective implementation of these methods in the upper primary schools are generally related to student, teacher, school, and resource and equipment related factors.

Total Delay in Treatment among Smear Positive Pulmonary Tuberculosis Patients in Five Primary Health Centers, Southern Ethiopia: A Cross Sectional Study
Anteneh Asefa, Wondu Teshome
PLOS ONE , 2014, DOI: 10.1371/journal.pone.0102884
Abstract: Introduction The global burden of Tuberculosis (TB) remains enormous. Delay in TB diagnosis may lead to a higher infectious pool in the community and a more advanced disease state at presentation increasing the risk of mortality. This study is conducted to determine the total delay before treatment among smear positive Pulmonary Tuberculosis (PTB) patients. Methods A health institution based cross sectional study was conducted in five primary health centers in southern Ethiopia from June to December 2012. A total of 328 smear positive PTB patients were enrolled in the study. A structured and pre-tested questionnaire was used. Median patient, diagnostic, and treatment delays were calculated to determine the total delay. Multiple logistic regression analysis was used to identify factors associated with total delay. Results The median patient, diagnostic, treatment and total delays measured in days were 30 (IQR 20.2, 60), 7 (IQR: 3, 14), 3 (IQR: 1, 4) and 45 (IQR: 34.5, 69.5) days respectively. Patients for whom treatment was not initiated within 45 days of onset of symptom(s) (total delay) constituted 49% of the study participants (59.5% among males and 39.2% among females; P<0.001). Total delay was found to be associated with: being female [AOR = 0.34, 95% CI: 0.18–0.62], having attended tertiary level education [AOR = 0.11, 95% CI: 0.02–0.55], perceived severity of stigma during the current TB disease course [AOR = 2. 18, 95% CI: 1.07, 4.42] and living in houses with higher family size [AOR = 0.26, 95% CI: 0.11, 0.61]. Conclusion Total delay in treatment of TB is still high in the study area. Patient's sex, perceived stigma, educational status and family size are significantly contributing for total delay. Therefore, a concerted effort should be taken in order to improve health seeking behavior of the community on TB and to reduce delays from seeking care after experiencing TB symptoms.

Abstract:

This article analyzed determinants of gross margin income from fishing to the rural households around Lake Ziway and Langano in Ethiopia. Four districts adjacent to the two lakes were selected purposively from which 179 respondents drawn randomly. Both primary and secondary information comprises of household structure and assets, climate factors and supportive services were organized. Data analysis employed descriptive statistics, budgetary analysis and the Ricardian method. Budgetary analysis showed positive fish gross margin income (GMI) of ETB 3,023.40 to average fisher. The Ricardian analysis made use of the climate only model (Model 1) and comprehensive model (Model 2). Using Model 1, water level raise due to inflow is vital to earn fair income in addition to the rainfall amount in Season 1, which is supported with positive impact of precipitation water level interaction on fish income. Impact of precipitation was positive in Season 3, due to meher rainfall and withdrawal of fishing labor to join agriculture that minimized over fishing. Using Model 2, precipitation water level interaction has positive impact in Season 2 due to better inflow and Meher rainfall. The interaction term was negative in Season 4 attributed to decreased water level, dry weather and less precipitation. The result also showed positive impact of household members participation, participation in the traditional financial arrangement and capacity to finance

operating costs. The study highlights problems facing fishing business like: decreased lake size and water volume, lake turbidity and siltation, open access and weak institutional arrangement to guide fishing efforts, wetland farming and expansion of irrigation to the lake side, cost of fishing materials, minimum sales price as well as poor access to the fish market. Hence,

These nanoparticles have potential applications in clinical medicine and bioimaging, and thus their possible adverse events require thorough investigation. The primary aim of this work was to explore whether the nanoparticles are biocompatible with pneumatocyte bioenergetics (cellular respiration and adenosine triphosphate content). Other objectives included assessments of caspase activity, lung structure, and cellular organelles. Pneumatocyte bioenergetics of murine lung remained preserved after treatment with C–SiO2-etched or C–SiO2 nanoparticles. C–SiO2-etched nanoparticles, however, increased caspase activity and altered lung structure more than C–SiO2 did. Consistent with the known mitochondrial toxicity of cobalt, both C–Co–SiO2 and C–Co3O4–SiO2 impaired lung tissue bioenergetics. C–Co–SiO2, however, increased caspase activity and altered lung structure more than C–Co3O4–SiO2. The results indicate that silica shell is essential for biocompatibility. Furthermore, cobalt oxide is the preferred phase over the zerovalent Co(0) phase to impart biocompatibility to cobalt-based nanoparticles.

Ethiopian Journal of Health Development , 2000,
Abstract: A one year live birth cohort of all identified children born in Jimma, Keffa and Illubabor Zones of Southwest Ethiopia, was followed from birth to the end of the first year of life, or to an earlier death, to investigate factors associated with mortality. All identified live-born infants were visited as soon as they were born and then bimonthly to the age of one or early death or lost for follow-up. Information was collected on socio-economic, behavioral, biological, and environmental factors for infants, mothers, and family immediately after birth and in consecutive visits. Overall, infant mortality was 106.2/1000, with estimates of 97.0/1000 and 113.5/1000 for urban and rural areas, respectively. Based on the results of the final Cox Proportional Hazards Model, mortality was associated with mothers' education and with antenatal care follow-up: there was better survival with at least one antenatal care follow-up. It was not associated with the mother's age per se but with marital status. Birth weight was strongly associated with infant mortality, and boys were more likely to die than girls. Twins were much more likely to die than singletons, even after taking their birth weight into account. Once adjustment had been made for these variables, there was no independent effect of the mothers' ethnic group or religion, or of family income. Family size was found to be significantly associated with infant mortality and higher mortality rate to families with the 2-4 persons. The type of water supply to the home was not associated with mortality, but habit of use of soap by the mother in washing her hands was. These results suggest that improvements in survival could be brought about by attempts to improve maternal education, antenatal care attendance, and habit of soap use in washing her hands which are amenable for change with local resources.

Ethiopian Journal of Health Development , 2002,
Abstract: Background: data from different studies showed health care behaviour and estimated per capita health care expenditure for the general population, but the specific data for infants at different levels of care are lacking. The objectives of this study were to describe mothers' health service utilization during pregnancy and delivery, determine their health seeking behaviour and health care expenditures for infants during the first year of life. Methods: The study was longitudinal community based study consisted of a cohort of 8273 live births, their mothers and families between September 1992 and October 1994 in rural and urban settings in Jimma, Illubabor and Kefecho Zones, Southwest Ethiopia. Mothers were interviewed for their health care utilization during pregnancy and delivery. Occurrences of any illness for infants and mothers health care utilization during pregnancy and delivery. Occurrence of any illness for infants and mothers health seeking behavior was collected with the bimonthly visit for a period of 12 months. Results: Mothers' health seeking behaviour for ill babies at the various levels of care showed that 46.5, 42.7, 48.241.6 percent of diarrhea, cough, fever, and other illnesses, respectively, got treatment in health institutions. More than a quarter of ill-infants didn't get any kind of help be it at home, traditional or health institutions. The average health care expenditure in infancy was estimated to be 7.92 birr and it increased with increasing level of education and monthly family income. In all treatment groups about 43 to 58 percent of ill infants claimed to have been cured with highest cure proportion for diarrhea cases after the first treatment was given. Conclusion: improved socioeconomic status of families and at least elementary schooling of mothers would change mothers' behaviour in seeking care for infants in health institution and increase the power of the family to spend some of their earnings for better care. Improving and providing at least primary health care services in rural areas needs considerations on the side of planners and health care provider.
