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 𝑅0𝑚𝑙 < 1.Conversely, if 𝑅0𝑚𝑙 > 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 𝐷, which incorporatesall optimal controls, namely malaria prevention 𝜔1(𝑡), leptospirosis prevention 𝜔2(𝑡), insecticidecontrol measure for malaria 𝜔3(𝑡), control sanitation rate of the environment 𝜔4(𝑡) is the mosteffective in minimizing our objective function. We also conduct a cost-effectiveness analysis toidentify the predominant strategy in terms of cost among the optimal strategies.

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

Background: Staphylococcus aureus is a major pathogenic bacterium associated with high morbidity and mortality worldwide. It exhibits resistance to multiple antibiotics, complicating treatment options. Despite its clinical significance, there is limited data on the prevalence of S. aureus infections and the patterns of methicillin and inducible clindamycin resistance, particularly in Ethiopia. Understanding these resistance trends is essential for guiding appropriate therapy and improving patient outcomes.
Objective: To assess the prevalence of S. aureus, methicillin and inducible clindamycin resistance patterns, and associated factors among patients with suspected bacterial infection at Debre Markos Comprehensive Specialized Hospital, Northwest Ethiopia.
Method: A hospital-based cross-sectional study was conducted among patients suspected of bacterial infections from 10 June 2023 to 28 February 2024. Blood, wound swab, cerebrospinal fluid, urine, eye swab, synovial fluid, ear swab, and pleural fluid were collected aseptically and inoculated onto appropriate media. S. aureus was identified based on colony morphology, Gram staining, DNase test and biochemical tests. Antimicrobial susceptibility testing was performed on the isolates using the disk diffusion and the D-test techniques based on CLSI guideline. Data were entered into SPSS version 26 for analysis. Logistic regression was applied to assess the relationship between predictors and the outcome variable. A P-value of ≤ 0.05 with a 95% CI was considered statistically significant.
Results: Among the 339 study participants, 38 (11.2%) (95% CI: 8-15) tested positive for S. aureus. Of these isolates, 14/38 (36.9%) were resistant to methicillin, 5/38 (13.1%) isolates were resistance to clindamycin by routine disk diffusion test whereas 10/38 (26.3%) isolates exhibited inducible clindamycin resistance using the D-test. The level of multidrug resistance was noted in 10/38 (26.3%) of the isolates. Significant factors associated with S. aureus infection included illiteracy (AOR = 13.51; 95% CI: 3.56-21.90; P = 0.018), having larger family size (AOR = 12.14; 95% CI: 2.38-20.43; P = 0.024), and income level of less than 3,000 ETB (AOR = 6.20; 95% CI: 1.03-30.09; P = 0.046).
Conclusion: The study revealed an 11.2% occurrence of S. aureus among the study participants, with a substantial proportion exhibiting methicillin resistance (36.9%) and inducible clindamycin resistance (26.3%). These findings highlight a higher burden of clindamycin resistance in MRSA, underscoring the need for routine D-test screening to guide appropriate antibiotic therapy. Additionally, factors such illiteracy, low income and residing in rural areas were associated with S. aureus infection. Targeted health education initiatives should be implemented, especially in rural areas and among populations with low literacy levels, to improve hygiene practices and reduce transmission.

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.
