The present day Ethiopia is in multifaceted socio-political crisis. One can mention a number of reasons for the presence of these crisis nation wide. But, needless to say, the venomous ethnic, language and religion based teachings and conceptions that has been sewed to the virgin minds of Ethiopian people for years through ‘anti narratives’ take the lion share. They seriously infected the socio-cultural, religious and cultural assets of the people and destroyed the strong fabrics that form the edifice of Ethiopia as a country. Many Ethiopians including the elite group, have been propagating these anti narratives and have been subserviently celebrating their catastrophic consequences. However, apart from being a lip service for elits and the government, the nature and contribution of these anti narratives for the present socio-political crisis is not studied in a scholarly fashion yet. The components of these anti narratives, the motif and motive behind them and the means of transmission to the generation are not well identified and investigated yet. The present researchers strongly believe that ttheir absence of in depth scientific investigation on anti narratives makes the effort to bring a solution as a nation very difficult and almost impossible.
The present research , therefore, atempted to be part of the nationwide effort to tackle these anti narratives and show the possible solution for the effects they have created on the nation so far at large and the Amhara people in particular. To ttheir effect, a special focus is given to Amhara region, as it is not only one of the most affected areas by these antinarratives but also it is an area being in a serious socio political crisis. Narrative analysis is used as a research design and the data collection, sampling and analysis methods employed in ttheir research will be guided by the principles of ttheir design.

INVESTIGATION OF IRON MINERALIZATION IN GONCHA, EAST GOJJAM, ETHIOPIA
ABSTRACT The main objective of the research is to investigate iron deposit by using petrographic, geochemical, XRD and geophysical results. To achieve the desired objective, secondary data compilation and interpretation, field work and post-field work (including petrographic result, geochemical result, XRD and geophysical result analysis) have been conducted. The study area is comprised of both Mesozoic sedimentary rocks and Tertiary - Quaternary volcanic rocks. The sedimentary rocks include sandstone, limestone, and shale, whereas the volcanic rocks are basalt and trachyte. Ternary diagrams of Al2O3-Fe2O3-SiO2 are commonly used to determine the degree of laterization. As laterization progresses increases, silica is leached out of the rock, leaving behind iron oxides. Fe2O3-rich samples are indicative of higher degrees of lateritization, while SiO2-rich composition experienced weak lateritization (Meyer et al., 2002). Data points for iron ore samples from the study area, were plotted in moderate to strong lateritization field. Hematite, magnetite, goethite and siderite are the primary ore minerals, according to both polished section petrography and XRD investigations. Furthermore, the main gangue phases in the region are anatase, quartz and kaolinite. The mineral concentration is between 20.16 and 71.88% hematite, 7–40% goethite, 1–30 siderite, and 1-3 percent magnetite. Approximately 5–10.5% kaolinite, 3–25% quartz, and 0.5% anatase are among the related gangue minerals. Varying amplitudes of magnetic anomaly signature indicates that the ore body is not evenly distributed along the respective profile across the study area and the ore bodies suspected to be magnetic mineral exist near surface to medium depth which is between 23.33m to 52.5m. Iron occurrence resource estimation was done by a conventional approach methods, such as, resources = A (m2) *T (m) * ρ (g/cm3). As a result the total tonnage of iron resource is about 17,844,964.452 tons. Key words: Iron deposit, magnetic anomaly, geochemical result, geological map, host rock

Knowledge and associated factors of patients towards informed consent in obstetric and gynecologic surgical procedures at Debre Markos Comprehensive Specialized Hospital, Ethiopia
Background: Informed consent (IC) is a principle in medical ethics and medical law that a patient must have adequate information and understanding before making decisions about their medical care. It is very essential for both clinician and patient in surgery and should be seen as a usual activity. Knowledge is one of the main intervention tools to improve patient comprehension in informed consent for surgical patients. In Ethiopia, little is known about the knowledge level and its determinant factors toward obstetric and gynecologic surgical informed consent. Due to this reason, this study aimed to assess the level of knowledge and associated factors of surgical informed consent among patients who underwent obstetric and gynecologic surgery at Debre Markos Comprehensive Specialized Hospital.
Methods: An institutional-based cross-sectional study was conducted from 28 November to 30 December 2023, among 298 postoperative women admitted to Debre Markos Comprehensive Specialized Hospital. Data were collected using a pretested, structured interviewer-administered questionnaire by using a systematic random sampling technique. The collected data were entered into EpiData version 4.6 and then exported to SPSS statistical software version 25 for analysis. A multivariable logistic regression analysis was employed to estimate the effect of independent variables on the outcome variable. An adjusted odds ratio [adjusted odds ratio (AOR)] with a 95% confidence interval (CI) was computed to report the presence of association between the dependent and independent variables. Statistical significance was determined at a P-value of

Male involvement in infant care is an effective intervention to improve infant health outcomes. However, evidence regarding male involvement in infant care and its associated factors is limited in Ethiopia. To assess the male involvement in infant care and associated factors among infants less than one year in Bibugn district of Ethiopia. A community-based cross-sectional study was conducted among 606 participants from April 1-30/2023. A systematic sampling technique was used to select each study participant. Data was collected using interviewer-administered questionnaires. Data were entered into Epi data 4.6 and analyzed using statistical Product Service and Solution (SPSS) version 2 5. Both descriptives, mean, frequency and analytical statistics were employed. Variables with a p-value of less than 0.25 in bivariate logistic regression were entered into a multivariate logistic regression to identify associated factors. Statistical significance was declared at p < 0.05. The prevalence of male involvement in infant care was 42.2% with a 95% CI (38.26-46.12). Male who did not attend formal education (AOR = 0.24, 95% CI = 0.14-0.43), having one child (AOR = 5.66, 95%CI = 2.94-10.88), having male infants (AOR = 2.51, 95% CI = 1.60-3.95), first infant order (AOR = 2.70, 95% CI = 1.36-5.39), having adequate knowledge towards infant care (AOR = 5.56,95% CI = 0.12-0.28), and having favorable attitude towards infant care (AOR = 1.70,95% CI = 0.34-0.99) were factors associated with male involvement in infant care. Less than 50% ( 50%) of males are involved in their infant care. Educational status of males, number of infants, male infants, male knowledge, and attitude towards infant care were significantly associated with involvement in infant care. Therefore, efforts should be directed at improving males' educational status, knowledge, and attitude to improve their engagement in caring for their infants.

Small scale irrigation (SSI) technologies offer a promising solution to address challenges of low agricultural productivity, unreliable rainfall, and rural poverty in Ethiopia. However, their performance and sustainability remain inconsistent, particularly in regions like East Gojjam Zone, Amhara Region. This study aimed to assess the adoption trends, performance challenges, and economic viability of furrow irrigation and motor pump systems across two districts Debre Elias and Machakel. A cross sectional, mixedmethods design was employed, drawing on data from 280 smallholder farmers selected through a multistage sampling procedure. Descriptive analysis showed moderate irrigation access, but a 25.4% overall defect rate raised concerns about technology reliability. Binary logistic regression identified income, credit access, and training as key factors reducing defect occurrence, while motor pump use and larger irrigated areas increased risk. Economic analysis revealed that furrow systems were more profitable, yielding a higher five year Net Present Value and Benefit Cost Ratio than motor pumps. Despite these gains, sustainability challenges persisted, including soil degradation and inefficient water use. The study also found notable district level variation, with furrow systems dominating in Debre Elias due to affordability, and topography favoring gravity flow and motor pumps preferred in Machakel for their productivity potential. Qualitative findings highlighted high maintenance costs and limited institutional support as barriers to sustained use. Based on these insights, the study recommends strengthening farmer access to credit, improving training services, and upgrading irrigation technologies to enhance the long term impact of SSI on smallholder livelihoods and agricultural sustainability

The use of long acting contraceptive methods is a commonpractice among women seeking to prevent unintended pregnanciesand plan their families. This study seeks to identify factors associ-ated with the practice of long-acting contraceptive methods, par-ticularly in a conflict-affected area in Awi zone, North WestEthiopia. A cross-sectional study was conducted on a multistagerandom sample of 1,334 women’s. Bivariable and multivariablebinary logistic regression has been applied to identify determinantfactors. Among the 1,334 women surveyed, 25.49% reportedusing long-acting contraceptive methods. The analysis revealedthat women’s educational level, wealth index, being visited byhealth extension, marital status, use of children as a source ofincome, and occupational status of women were factors signifi-cantly hindering the use of long-acting contraceptive methods inthe area. In conclusion, higher contraceptive use was observedamong educated, married women, women who used children as asource of income, and women employed by the government. It istherefore recommended that government officials in Awi Zone andpolicy makers should implement programs to increase female edu-cation and employment, which could lead to greater use of contra-ceptive methods for effective family planning.

Melioidosis is a significant health problem in tropical and subtropical regions, especially inSoutheast Asia and Northern Australia. Recurrent melioidosis is a major obstacle to eliminatingthe disease from the community in these nations. This work aims to propose and analyzea human melioidosis model with recurrent phenomena and an optimal control model byincorporating time-dependent control functions. The basic reproduction number (𝑅0) of theuncontrolled model is derived using the method of the next-generation matrix. Using theconstruction of a Lyapunov functional, we present the global asymptotic dynamics of theautonomous model in the presence of recurrent for both disease-free and endemic equilibria. Theglobal asymptotic stability of the model’s equilibria shows the absence of a backward bifurcationfor the model in both cases, whether in the absence or presence of relapse. The sensitivityanalysis aims to identify the parameters that have the most significant impact on the model’sdynamics. Furthermore, qualitative analysis of the model’s global dynamics and the changingeffect of the most influential parameters on 𝑅0 are supported by numerical experiments, with theresults being illustrated graphically. The model with time-dependent controls is analyzed usingoptimal control theory to assess the impact of various intervention strategies on the spread ofthe epidemic. The numerical results of the optimality system are carried out using the Forward–Backward Sweep method in Matlab. We also conducted a cost-effectiveness analysis using twoapproaches: the average cost-effectiveness ratio and the incremental cost-effectiveness ratio.

This study investigates the status of biomass stove usage in East Gojjam, Ethiopia, and evaluates the health, economic, and environmental benefits of an improved biomass stove which was designed and fabricated using locally available materials. Major challenges in the study areas were uses of traditional three-stone stoves, which are inefficient and produce harmful emissions. The study aims to assess the status of stoves used, source, amount and type of biomass consumption per household, to analyze the health impact of improved biomass stove with conventional stove and to analyze the economic and environmental impact of the conventional and improved stove.Two stove models were fabricated: one for household use and another for institutional settings. Construction materials included angle iron, sheet metal, ceramic tiles, sand, and clay for insulation. Eucalyptus wood a commonly used local biomass fuel was standardized for all testing, including oven drying and storage procedures. Performance evaluation was based on cooking time, fuel consumption, and emissions (CO and PM2.5), using laboratory and field tests. Additional data were collected through surveys, interviews, focus group discussions, and direct observations from 400 households across three districts: Dejen, Yedwuha and Debrework.According to the result; the improved biomass stove significantly outperformed the conventional three stone stove: reducing cooking time by 51.61%, fuel consumption by 12.34%, carbon monoxide emissions by 99.72%, and PM2.5 emissions by 75.52%. It also demonstrated substantial environmental benefits, including lower firewood demand and reduced deforestation. Economically, households saved over 3,225 birr per year in fuel and time costs.In conclusion, the improved biomass stove offers a viable, scalable solution to Ethiopia’s household energy and health challenges. Its adoption can significantly mitigate household air pollution, improve public health, reduce environmental degradation, and strengthen economic resilience, particularly for women and children.

This study investigates the status of biomass stove usage in East Gojjam, Ethiopia, and evaluates the health, economic, and environmental benefits of an improved biomass stove which was designed and fabricated using locally available materials. Major challenges in the study areas were uses of traditional three-stone stoves, which are inefficient and produce harmful emissions. The study aims to assess the status of stoves used, source, amount and type of biomass consumption per household, to analyze the health impact of improved biomass stove with conventional stove and to analyze the economic and environmental impact of the conventional and improved stove.Two stove models were fabricated: one for household use and another for institutional settings. Construction materials included angle iron, sheet metal, ceramic tiles, sand, and clay for insulation. Eucalyptus wood a commonly used local biomass fuel was standardized for all testing, including oven drying and storage procedures. Performance evaluation was based on cooking time, fuel consumption, and emissions (CO and PM2.5), using laboratory and field tests. Additional data were collected through surveys, interviews, focus group discussions, and direct observations from 400 households across three districts: Dejen, Yedwuha and Debrework.According to the result; the improved biomass stove significantly outperformed the conventional three stone stove: reducing cooking time by 51.61%, fuel consumption by 12.34%, carbon monoxide emissions by 99.72%, and PM2.5 emissions by 75.52%. It also demonstrated substantial environmental benefits, including lower firewood demand and reduced deforestation. Economically, households saved over 3,225 birr per year in fuel and time costs.In conclusion, the improved biomass stove offers a viable, scalable solution to Ethiopia’s household energy and health challenges. Its adoption can significantly mitigate household air pollution, improve public health, reduce environmental degradation, and strengthen economic resilience, particularly for women and children. The study recommends expanding the dissemination of the improved biomass stoves through targeted policy support, community education, and financing mechanisms.
