Design, development, and performance evaluation of carrot washing and grading machine
No full textCarrot washing and grading is performed after harvesting and before transporting to the market has been done with traditional methods by farmers in Ethiopia with too tedious, much time, and labor-consuming which leads to health problems, Fertile soil erosion, discouraging for carrot production and river water pollution. The main objective of this study was to design, develop, and perform the evaluation of carrot washing and grading machine after harvesting before transporting to market that was not used for cooking purposes to alleviate the above-stated problems. During design, a power source, initial speed, and discharge capacity of the pump were considered as 50W, 60rpm, and 0.036l/s respectively based on literature reviews. Performance of this machine evaluation was carried out with Nantey variety at two levels of feeding loads 10kg and 15 kg at different drum speeds; 14rpm, 21rpm, and 28rpm. The data was collected in both qualitative and quantitative methods and the collected data were analyzed by using Statistical Package for the Social Sciences software (SPSS) at a 5% level of significance. The overall mean results obtained for performance indicators in terms of time required to complete washing and grading activities, washing efficiency, grading efficiency, percentage of damage tuber, and throughout put capacity were recorded as 2.22minutes, 98.70%, 92.23%, 1.21%, and 242.17 kg/hr respectively. The evaluation results indicated the time required of 2 to 10.88minutes, washing efficiencies of 84.87 to 98.70 % for the range of the variable of drum speed between 14 to 28 rpm and for the range of the variable of feeding load 10-15kg. The grading efficiency increased 72.89 to 92.23% as the speed increased (14 to 28 rpm), for the feeding load increased from10 to 15kg. The carrot washing and grading machine is simple to operate and maintain without formal education and the machine was fabricated from locally sourced materials. The unit cost of this machine was birr 16363.52, which is cheap and can be afforded by an average of Ethiopian farmers
A post-traumatic stress disorder among internally displaced people in sub-Saharan Africa: a systematic review
No full textIntroductionDespite the prevalence of post-traumatic disorder in internally displaced persons, which is well established, and the fact that respective international organizations are working on the issues, little attention is given in the context of sub-Saharan Africa, This study aims to review the available data about the prevalence and determinants of post-traumatic stress disorders among internally displaced people in sub-Saharan Africa.MethodsStudies published in the English language that have a clear outcome of interest and are available in full text were included. Six electronic databases were searched to identify published studies on the prevalence and determinants of posttraumatic stress disorder among IDPs in sub-Saharan Africa. This includes PubMed/MEDLINE, Scopus, EMBASE, PsychInfo, and the Web of Science. All relevant studies till June, 2023 were assessed. The review was done as per the Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA-2009) and registered on PROSPERO (CRD420222997111).ResultsOriginally, 33,138 articles were found in six databases, and finally, eleven studies were reviewed. The prevalence of post-traumatic stress disorder in sub-Saharan African countries was disproportionately presented in this review, ranging from 12.3% in Central Sudan to 85.5% in Nigeria. From a total of 11 studies, eight of them reported more than 50% of the magnitude of post-traumatic stress disorder, pointing to a higher magnitude of the prevalence of post-traumatic stress disorders in the region. The study identified numerous factors that contributed to post-traumatic stress disorder among the internally displaced population. Female gender, depression, anxiety, stress, being single, low level of educational status, experiencing or witnessing traumatic events, and psychological trauma were evidenced for their association with post-traumatic stress disorder.ConclusionThese results demonstrate a higher prevalence of post-traumatic stress disorder compared to other regions of the world. The participants’ socio-demographic characteristics, including age, being single, being female, and a low level of education, were identified as factors contributing to PTSD. Moreover, the review identified that depression, anxiety, and experiencing or witnessing traumatic events were also influencing factors for PTSD among IDPs. The concerned bodies need to reinforce the monitoring and evaluation of the mental health programs of IDPs in the region.Systematic review registrationhttps://www.crd.york.ac.uk/prospero/display_record.php?RecordID=299711, CRD42022299711

Image_1_Knowledge, attitude, and its correlates of the community toward mental illness in Mattu, South West Ethiopia.TIFF
No full textBackgroundThe magnitude of mental health conditions in the general population was high in low-resource settings like Ethiopia. This was accompanied by little evidence on knowledge, attitudes, and related determinants in the general population. Therefore, the current survey is planned to assess the knowledge, attitude, and related factors of the community toward mental illness in Mattu, South West Ethiopia.ObjectivesOur study aimed to assess the knowledge, attitude, and related factors of the community toward mental illness in Mattu, South West Ethiopia.MethodsA community-based cross-sectional survey was conducted in South West Ethiopia, Mattu town from 1 April−20 June, 2022 using a systematic random sampling, a multistage stratified technique from 649 households, and employed an interviewer-administered pre-tested semi-structured English version questionnaire. Epi-data Version 3.1 and SPSS-V-23.3 were employed for data entry and analysis respectively. A statistically significant association was declared at a P-value ≤ 0.05 at a 95% confidence interval.ResultsIn the current study, poor knowledge regarding, and unfavorable attitudes toward, mental illness among study respondents were 28% (182) 95% CI (24.3, 31.6) and 60.4% (392) 95% CI (56.5, 64.3), respectively. After controlling for potential confounders, being self-employed was independently associated with poor knowledge [AOR = 3.1, 95%CI (1.65, 4.28)]. Moreover, current use of substances [AOR = 1.64 95%CI (1.09, 5.98)] and not hearing information about mental illness from social media have been shown to be associated in the final model with an unfavorable attitude [AOR = 3.44 95%CI (1.98, 5.99)].Conclusion and recommendationAbout one-third and more than one-half of the study participants showed poor knowledge and an unfavorable attitude, respectively. Compared to similar global and local findings, there was better community knowledge and a poor attitude toward mental illness in the area. Unfavorable attitudes toward mental illness were found to be exacerbated by participants not hearing about it on social media and by current substance use. Moreover, being self-employed was independently associated with poor knowledge of mental illness. Hence, all concerned stakeholders need to enhance mental health advocacy to improve public knowledge and attitude toward mental illness through media campaigns with a special focus on common substances. In addition, due attention should be given to self-employed groups of society to reduce the impacts of mental health conditions.</p
