Althoug h⁠ the country has made promising progress, especially through first and second-leve⁠l rural land registration and certification programs, urban land cadastral registratio n re mai⁠ns underdeveloped, characterized by incomplete coverage, institutional fragmentation, and widespread informal landholding. The study use d a mixed research method by c ollecting both quantitative and qualitative data. For the quantitative data, about 385 respon⁠dents were surveyed across six ru ral and urban sites, whereas the qualitative data we⁠r⁠e collected using ke y i⁠nformant interviews and focus group di⁠scussions. The research was conducted under university sponsorship during a period of restricted field acc⁠ess due to conflict-related⁠ limitations. The co llected d ata were analysed using both descriptive and thematic approaches to compare the⁠ urban and rural areas. The findings show deep stru⁠ctural disparities between urb an and rural a reas. Rura⁠l areas have achieved broader certi fication cover⁠age and higher percei ved tenure security due to co⁠nsist⁠ent⁠ program i mplementat⁠ion, yet still face ser ious challenges, including poor da⁠ta systems, limited skilled⁠ personne⁠l, weak enforcement, and reliance on customary practices. Urba n areas, w⁠hi le more technologically equipped and instit utionally resourced, stru ggle⁠ with legal ambiguities, fragmented governance, high registr⁠ation costs, and informality in peri-urban zone⁠s. The cadastral disparities contribute to unequal tenure security, land disputes, unequal access to land⁠based credit, and unbalanced development outcomes. The study concludes that minimizing the gaps needs harmonized legal frameworks, integrated and coordinated institutions, an d targeted support for both urban and rural cadastral systems.

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 ā€˜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.

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

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

Background Providing timely first-aid by trained responders can reduce deaths and disabilities from road trafficaccidents, a leading global cause of death. Ethiopia ranks 19th worldwide and 4th in Africa. Therefore, this studyassesses the knowledge and, attitudes toward emergency first aid, and its factors among public transport drivers inInjibara, Ethiopia.Objective To assess the Knowledge, and Attitude towards first-aid utilization and its associated factors among PublicTransport Service Drivers in Injibara, Northwest Ethiopia, 2023.Methods A cross-sectional study was conducted involving 419 public transport drivers, selected systematicallybased on vehicle side numbers, starting with a random choice for the first respondent. Subsequent participants werechosen at every second interval (k = 2). A structured questionnaire was used to collect relevant data. Binary logisticregression was performed using SPSS V.26 to assess the associations between independent and dependent variables.The strength of these associations was measured using odds ratios and 95% confidence intervals, with a P-value < 0.05deemed statistically significant.Result The study revealed that the prevalence of good knowledge and favorable attitudes toward first-aid utilizationwas 33.2% and 38.2%, respectively. Participation in first-aid training (AOR = 0.566, p = 0.027), access to a first-aid kit(AOR = 1.65, p = 0.027), and prior experience using first-aid at accident scenes (AOR = 0.476, p = 0.014) were factorsassociated with better first-aid utilization. Drivers who had used a first-aid kit (AOR = 0.476, p = 0.014) and thoseexposed to training (AOR = 0.486, p = 0.034) demonstrated more positive attitudes toward first aid.Conclusion The knowledge and attitude toward first-aid utilization remain low. Participation in first-aid training,access to first-aid kits, and experience using them during accidents were factors associated with improvedknowledge. Additionally, drivers who have used first-aid kits and received training tend to have a favorable attitude
toward their use. Therefore, relevant authorities must enhance the availability of first-aid kits, increase the exposure ofdrivers, and provide training to drivers to increase their knowledge and favorable attitude towards first-aid utilization.Clinical trial number Not applicable.Keywords Knowledge, Attitude, First aid, Transport service, Ethiopia

Abstract: The continuous reduction in peri-urban agricultural land due to spatial urban expansionforces subsistence farmers to seek arable land through different land access strategies. Among these,land rental transactions are crucial for accessing arable land across different regions. This studyaimed to examine factors affecting land rental transactions in the peri-urban areas of the East GojjamAdministrative Zone in Ethiopia. Data were collected from 353 household heads of peri-urban areas,who were affected by expropriation. A total of 350 valid responses were analyzed using descriptiveand inferential statistics and an econometrics model. The results indicated that 58% of the respondentsparticipated in both renting and renting out land, which underlines the importance of land rentaltransactions in the peri-urban areas. Specifically, 60% of female-headed households were engagedin land rental transactions, with 14% renting in and 46% renting out land. In contrast, 38% of themale-headed respondents rented land, while only 19% rented out land. The model result identifiedsex, landholding size, number of oxen, participation in off-farm activities, and extension service assignificant determinant variables for renting land. Households made land rental agreements bothorally and in written documents, with oral agreements being more prevalent. Transaction dueswere conducted through sharecropping and fixed rents, with sharecropping being the most commonmethod. Thus, land rental transactions play pivotal roles to support the livelihoods of peri-urbansubsistence farmers.Keywords: land rental; land scarcity; peri-urban; rent; rent out; impacts; gender

Malaria and leptospirosis are emerging vector-borne diseases that pose significant global healthproblems in tropical and subtropical regions. This study aimed to develop and analyze amathematical model for the transmission dynamics of malaria-leptospirosis co-infection withoptimal control measures. The model’s dynamics are examined through its two sub-models:one for malaria alone and the other for leptospirosis alone. We apply a next-generationmatrix approach to derive the basic reproduction numbers for the sub-models. By using thereproduction number, we demonstrate the local and global asymptotic stability of both disease-free and endemic equilibria in these sub-models. We perform numerical experiments to validatethe theoretical outcomes of the full co-infection model. The graphical results show that malaria-leptospirosis co-infection will be eradicated from the population through time if š‘…0š‘šš‘™ < 1.Conversely, if š‘…0š‘šš‘™ > 1, the co-infection will persist in the population. Furthermore, weinvestigate an optimal control model to demonstrate the impact of various time-dependentcontrols in reducing the spread of both diseases and their co-infection. We use the forward–backward sweep iterative method to perform numerical simulations of the optimal controlproblem. Our findings of the optimal control problem imply that strategy š·, which incorporatesall optimal controls, namely malaria prevention šœ”1(š‘”), leptospirosis prevention šœ”2(š‘”), insecticidecontrol measure for malaria šœ”3(š‘”), control sanitation rate of the environment šœ”4(š‘”) is the mosteffective in minimizing our objective function.

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.
Full Abstract:
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.

Abstract Preview:
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
