It serves as a source of food and nutrition, income and livelihood for many inhabitants. However, the fishery in Lake Hawassa shows a declining trend, especially for the most valuable species, such as the Nile tilapia (Oreochromis niloticus L.), indicating that the existing management systems are either not fully enforced or inadequate. The aim of this study was therefore to develop management policy options for the sustainable utilization and management of fishery resources in Lake Hawassa. A blend of primary and secondary data was used for the study. Primary data were collected using Participatory Rural Appraisal (PRA) techniques such as focus group discussions with members of fishing co-operatives, co-operative leaders and key informant discussion to understand the current state of the fisheries resources. Then literatures were reviewed to obtain secondary data and develop alternative management policy options. It has been realized that Lake Hawassa is not very species-rich in terms of fish diversity. It contains only six species belonging to four families, of which only three are commercially important, including the Nile tilapia (90 % of catches), the African catfish Clarias gariepinus B. (7 % of catches) and the African large barb Labeobarbus intermedius R. (only 3 % of catches). The production has been declining since 2007. The top six challenges that could be responsible for this decline, identified by about two-thirds of respondents and supported by the literature review, are directly linked to fisheries and fisheries management, with overfishing, irregular monitoring, control, and surveillance (MCS) system and the lack of a fishing licensing system ranking first, second and third respectively. It is, therefore, important to address these and other problems identified in the study. Of the management options analyzed, we suggest adapting the management approach to sustain the fishery in Lake Hawaasa and its socio-economic benefits. We also present important conditions for successfully implementing co-management in this and other lakes in Ethiopia. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=comanagement" title="comanagement">comanagement</a>, <a href="https://publications.waset.org/abstracts/search?q=community-based%20management" title=" community-based management"> community-based management</a>, <a href="https://publications.waset.org/abstracts/search?q=fishery" title=" fishery"> fishery</a>, <a href="https://publications.waset.org/abstracts/search?q=overfishing" title=" overfishing"> overfishing</a>, <a href="https://publications.waset.org/abstracts/search?q=participatory%20approach" title=" participatory approach"> participatory approach</a>, <a href="https://publications.waset.org/abstracts/search?q=top-down%20management" title=" top-down management"> top-down management</a> </p> <a href="https://publications.waset.org/abstracts/193181/development-of-intervention-policy-options-for-sustainable-fisheries-management-of-lake-hawassa-ethiopia" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/193181.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">10</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">44</span> Agro-Morphological Traits Based Genetic Diversity Analysis of ‘Ethiopian Dinich’ Plectranthus edulis (Vatke) Agnew Populations Collected from Diverse Agro-Ecologies in Ethiopia</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Fekadu%20Gadissa">Fekadu Gadissa</a>, <a href="https://publications.waset.org/abstracts/search?q=Kassahun%20Tesfaye"> Kassahun Tesfaye</a>, <a href="https://publications.waset.org/abstracts/search?q=Kifle%20Dagne"> Kifle Dagne</a>, <a href="https://publications.waset.org/abstracts/search?q=Mulatu%20Geleta"> Mulatu Geleta </a> </p> <p class="card-text"><strong>Abstract:</strong></p> ‘Ethiopian dinich’ also called ‘Ethiopian potato’ is one of the economically important ‘orphan’ edible tuber crops indigenous to Ethiopia. We evaluated the morphological and agronomic traits performances of 174 samples from Ethiopia at multiple locations using 12 qualitative and 16 quantitative traits, recorded at the correct growth stages. We observed several morphotypes and phenotypic variations for qualitative traits along with a wide range of mean performance values for all quantitative traits. Analysis of variance for each quantitative trait showed a highly significant (p<0.001) variation among the collections with eventually non-significant variation for environment-traits interaction for all but flower length. A comparatively high phenotypic and genotypic coefficient of variation was observed for plant height, days to flower initiation, days to 50% flowering and tuber number per hill. Moreover, the variability and coefficients of variation due to genotype-environment interaction was nearly zero for all the traits except flower length. High genotypic coefficients of variation coupled with a high estimate of broad sense heritability and high genetic advance as a percent of collection mean were obtained for tuber weight per hill, number of primary branches per plant, tuber number per hill and number of plants per hill. Association of tuber yield per hectare of land showed a large magnitude of positive phenotypic and genotypic correlation with those traits. Principal components analysis revealed 76% of the total variation for the first six principal axes with high factor loadings again from tuber number per hill, number of primary branches per plant and tuber weight. The collections were grouped into four clusters with the weak region (zone) of origin based pattern. In general, there is high genetic-based variability for ‘Ethiopian dinich’ improvement and conservation. DNA based markers are recommended for further genetic diversity estimation for use in breeding and conservation. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=agro-morphological%20traits" title="agro-morphological traits">agro-morphological traits</a>, <a href="https://publications.waset.org/abstracts/search?q=Ethiopian%20dinich" title=" Ethiopian dinich"> Ethiopian dinich</a>, <a href="https://publications.waset.org/abstracts/search?q=genetic%20diversity" title=" genetic diversity"> genetic diversity</a>, <a href="https://publications.waset.org/abstracts/search?q=variance%20components" title=" variance components"> variance components</a> </p> <a href="https://publications.waset.org/abstracts/86088/agro-morphological-traits-based-genetic-diversity-analysis-of-ethiopian-dinich-plectranthus-edulis-vatke-agnew-populations-collected-from-diverse-agro-ecologies-in-ethiopia" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/86088.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">190</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">43</span> Innovative In-Service Training Approach to Strengthen Health Care Human Resources and Scale-Up Detection of Mycobacterium tuberculosis</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Tsegahun%20Manyazewal">Tsegahun Manyazewal</a>, <a href="https://publications.waset.org/abstracts/search?q=Francesco%20Marinucci"> Francesco Marinucci</a>, <a href="https://publications.waset.org/abstracts/search?q=Getachew%20Belay"> Getachew Belay</a>, <a href="https://publications.waset.org/abstracts/search?q=Abraham%20Tesfaye"> Abraham Tesfaye</a>, <a href="https://publications.waset.org/abstracts/search?q=Gonfa%20Ayana"> Gonfa Ayana</a>, <a href="https://publications.waset.org/abstracts/search?q=Amaha%20Kebede"> Amaha Kebede</a>, <a href="https://publications.waset.org/abstracts/search?q=Tsegahun%20Manyazewal"> Tsegahun Manyazewal</a>, <a href="https://publications.waset.org/abstracts/search?q=Francesco%20Marinucci"> Francesco Marinucci</a>, <a href="https://publications.waset.org/abstracts/search?q=Getachew%20Belay"> Getachew Belay</a>, <a href="https://publications.waset.org/abstracts/search?q=Abraham%20Tesfaye"> Abraham Tesfaye</a>, <a href="https://publications.waset.org/abstracts/search?q=Gonfa%20Ayana"> Gonfa Ayana</a>, <a href="https://publications.waset.org/abstracts/search?q=Amaha%20Kebede"> Amaha Kebede</a>, <a href="https://publications.waset.org/abstracts/search?q=Yewondwossen%20Tadesse"> Yewondwossen Tadesse</a>, <a href="https://publications.waset.org/abstracts/search?q=Susan%20Lehman"> Susan Lehman</a>, <a href="https://publications.waset.org/abstracts/search?q=Zelalem%20Temesgen"> Zelalem Temesgen</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In-service health trainings in Sub-Saharan Africa are mostly content-centered with higher disconnection with the real practice in the facility. This study intended to evaluate in-service training approach aimed to strengthen health care human resources. A combined web-based and face-to-face training was designed and piloted in Ethiopia with the diagnosis of tuberculosis. During the first part, which lasted 43 days, trainees accessed web-based material and read without leaving their work; while the second part comprised a one-day hands-on evaluation. Trainee’s competency was measured using multiple-choice questions, written-assignments, exercises and hands-on evaluation. Of 108 participants invited, 81 (75%) attended the course and 71 (88%) of them successfully completed. Of those completed, 73 (90%) scored a grade from A to C. The approach was effective to transfer knowledge and turn it into practical skills. In-service health training should transform from a passive one-time-event to a continuous behavioral change of participants and improvements on their actual work. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ethiopia" title="Ethiopia">Ethiopia</a>, <a href="https://publications.waset.org/abstracts/search?q=health%20care" title=" health care"> health care</a>, <a href="https://publications.waset.org/abstracts/search?q=Mycobacterium%20tuberculosis" title=" Mycobacterium tuberculosis"> Mycobacterium tuberculosis</a>, <a href="https://publications.waset.org/abstracts/search?q=training" title=" training"> training</a> </p> <a href="https://publications.waset.org/abstracts/13878/innovative-in-service-training-approach-to-strengthen-health-care-human-resources-and-scale-up-detection-of-mycobacterium-tuberculosis" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/13878.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">504</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">42</span> Genome Analysis of Lactobacillus Plantarum and Lactobacillus Brevis Isolated From Traditionally Fermented Ethiopian Kocho and Their Probiotic Properties</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Guesh%20Mulaw">Guesh Mulaw</a>, <a href="https://publications.waset.org/abstracts/search?q=Haile%20Beruhulay"> Haile Beruhulay</a>, <a href="https://publications.waset.org/abstracts/search?q=Anteneh%20Tesfaye"> Anteneh Tesfaye</a>, <a href="https://publications.waset.org/abstracts/search?q=Tesfaye%20Sisay%20Diriba%20Muleta"> Tesfaye Sisay Diriba Muleta</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Probiotics are live microorganisms that, when administered in adequate amounts, promote the health of a consumer. The present work aims to study the whole genome sequence of probiotic strains of lactic acid bacteria (LAB) isolated from traditional Ethiopian fermented kocho for bacteriocin production and to evaluate their probiotic properties. LAB were isolated from traditionally fermented kocho samples and characterized following standard methods. Accordingly, a total of 150 LAB were isolated, of which 7 (4.67%) isolates showed 50.52-74.05% and 33.33-62.40% survival rates at pH 2 for 3 and 6 h, respectively. The 7 acid-tolerant isolates were also tolerated 0.3% bile salt for 24 h with 88.96 to 98.10% survival. The acid and bile salt-tolerant LAB isolates also inhibited some reference foodborne pathogenic bacteria to varying degrees. All 7 acid- and bile salt-tolerant isolates were susceptible to ampicillin, tetracycline and erythromycin. However, the potent isolates showed remarkable resistance to kanamycin. Likewise, four of the 7 isolates were resistant to streptomycin, but three of the 7 isolates were sensitive to streptomycin. The identification of the seven selected probiotic LAB isolates and their genetic relatedness was performed based on whole-genome sequence comparisons. Consequently, these isolates belonged to Lactobacillus species, including 6 Lb. plantarum, 1 Lb. brevis. Among the 7 potential probiotic LAB strains, BAGEL predicted 2 bacteriocin for class II in the genome of 7 strains. The 7 Lactobacillus strains were found to be potentially useful for producing functional products and could be suitable probiotic candidates for food processing industries <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=ferneted%20foods" title="ferneted foods">ferneted foods</a>, <a href="https://publications.waset.org/abstracts/search?q=kocho" title=" kocho"> kocho</a>, <a href="https://publications.waset.org/abstracts/search?q=probiotics" title=" probiotics"> probiotics</a>, <a href="https://publications.waset.org/abstracts/search?q=lactic%20acid%20bacteria" title=" lactic acid bacteria"> lactic acid bacteria</a> </p> <a href="https://publications.waset.org/abstracts/190134/genome-analysis-of-lactobacillus-plantarum-and-lactobacillus-brevis-isolated-from-traditionally-fermented-ethiopian-kocho-and-their-probiotic-properties" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/190134.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">29</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">41</span> Reducing Road Traffic Accident: Rapid Evidence Synthesis for Low and Middle Income Countries</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Tesfaye%20Dagne">Tesfaye Dagne</a>, <a href="https://publications.waset.org/abstracts/search?q=Dagmawit%20Solomon"> Dagmawit Solomon</a>, <a href="https://publications.waset.org/abstracts/search?q=Firmaye%20Bogale"> Firmaye Bogale</a>, <a href="https://publications.waset.org/abstracts/search?q=Yosef%20Gebreyohannes"> Yosef Gebreyohannes</a>, <a href="https://publications.waset.org/abstracts/search?q=Samson%20Mideksa"> Samson Mideksa</a>, <a href="https://publications.waset.org/abstracts/search?q=Mamuye%20Hadis"> Mamuye Hadis</a>, <a href="https://publications.waset.org/abstracts/search?q=Desalegn%20Ararso"> Desalegn Ararso</a>, <a href="https://publications.waset.org/abstracts/search?q=Ermias%20Woldie"> Ermias Woldie</a>, <a href="https://publications.waset.org/abstracts/search?q=Tsegaye%20Getachew"> Tsegaye Getachew</a>, <a href="https://publications.waset.org/abstracts/search?q=Sabit%20Ababor"> Sabit Ababor</a>, <a href="https://publications.waset.org/abstracts/search?q=Zelalem%20Kebede"> Zelalem Kebede</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Globally, road traffic accident (RTA) is causing millions of deaths and injuries every year. It is one of the leading causes of death among people of all age groups and the problem is worse among young reproductive age group. Moreover the problem is increasing with an increasing number of vehicles. The majority of the problem happen in low and middle income countries (LMIC), even if the number of vehicles in these countries is low compared to their population. So, the objective of this paper is to summarize the best available evidence on interventions that can reduce road traffic accidents in low and middle income countries (LMIC). Method: A rapid evidence synthesis approach adapted from the SURE Rapid Response Service was applied to search, appraise and summarize the best available evidence on effective intervention in reducing road traffic injury. To answer the question under review, we searched for relevant studies from databases including PubMed, the Cochrane Library, TRANSPORT, Health system evidence, Epistemonikos, and SUPPORT summary. The following key terms were used for searching: Road traffic accident, RTA, Injury, Reduc*, Prevent*, Minimiz*, “Low and middle-income country”, LMIC. We found 18 articles through a search of different databases mentioned above. After screening for the titles and abstracts of the articles, four of them which satisfy the inclusion criteria were included in the final review. Then we appraised and graded the methodological quality of systematic reviews that are deemed to be highly relevant using AMSTAR. Finding: The identified interventions to reduce road traffic accidents were legislation and enforcement, public awareness/education, speed control/ rumble strips, road improvement, mandatory motorcycle helmet, graduated driver license, street lighting. Legislation and Enforcement: Legislation focusing on mandatory motorcycle helmet usage, banning cellular phone usage when driving, seat belt laws, decreasing the legal blood alcohol content (BAC) level from 0.06 g/L to 0.02 g/L bring the best result where enforcement is there. Public Awareness/Education: focusing on seat belt use, child restraint use, educational training in health centers and schools/universities, and public awareness with media through the distribution of videos, posters/souvenirs, and pamphlets are effective in the short run. Speed Control: through traffic calming bumps, or speed bumps, rumbled strips are effective in reducing accidents and fatality. Mandatory Motorcycle Helmet: is associated with reduction in mortality. Graduated driver’s license (GDL): reduce road traffic injury by 19%. Street lighting: is a low-cost intervention which may reduce road traffic accidents. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=evidence%20synthesis" title="evidence synthesis">evidence synthesis</a>, <a href="https://publications.waset.org/abstracts/search?q=injury" title=" injury"> injury</a>, <a href="https://publications.waset.org/abstracts/search?q=rapid%20review" title=" rapid review"> rapid review</a>, <a href="https://publications.waset.org/abstracts/search?q=reducing" title=" reducing"> reducing</a>, <a href="https://publications.waset.org/abstracts/search?q=road%20traffic%20accident" title=" road traffic accident"> road traffic accident</a> </p> <a href="https://publications.waset.org/abstracts/148077/reducing-road-traffic-accident-rapid-evidence-synthesis-for-low-and-middle-income-countries" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/148077.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">164</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">40</span> Model Predictive Controller for Pasteurization Process</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Tesfaye%20Alamirew%20Dessie">Tesfaye Alamirew Dessie</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Our study focuses on developing a Model Predictive Controller (MPC) and evaluating it against a traditional PID for a pasteurization process.

However, to the best of the authors' knowledge, the effect of mixing water temperatures on plastic shrinkage cracking of concrete has not been studied yet. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=water%20temperature" title="water temperature">water temperature</a>, <a href="https://publications.waset.org/abstracts/search?q=early%20age%20concrete%20strength" title=" early age concrete strength"> early age concrete strength</a>, <a href="https://publications.waset.org/abstracts/search?q=mechanical%20properties%20of%20concrete" title=" mechanical properties of concrete"> mechanical properties of concrete</a>, <a href="https://publications.waset.org/abstracts/search?q=strength" title=" strength"> strength</a> </p> <a href="https://publications.waset.org/abstracts/186313/water-temperature-on-early-age-concrete-property" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/186313.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">57</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">38</span> Boryl Radical-Promoted Dehydroxylative Alkylation of 3-Hydroxyoxindole Derivatives</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Tesfaye%20Tebeka%20Simur">Tesfaye Tebeka Simur</a>, <a href="https://publications.waset.org/abstracts/search?q=Tian-Yu%20Peng"> Tian-Yu Peng</a>, <a href="https://publications.waset.org/abstracts/search?q=Yi-Feng%20Wang"> Yi-Feng Wang</a>, <a href="https://publications.waset.org/abstracts/search?q=Xiu-Wei%20Wu"> Xiu-Wei Wu</a>, <a href="https://publications.waset.org/abstracts/search?q=Feng-Lian%20Zhang"> Feng-Lian Zhang</a> </p> <p class="card-text"><strong>Abstract:</strong></p> A boryl radical-promoted dehydroxylative alkylation of 3-hydroxy-oxindole derivatives is achieved. The reaction starts from addition of 4-dimethylaminopyridine (DMAP)-boryl radical to the amide carbonyl oxygen atom, which induces a spin-center shift process to promote the C−O bond cleavage. The elimination of a hydroxide anion from a free hydroxy group is also accomplished. Capture of the generated carbon radical with alkenes furnishes a variety of C-3 alkylated oxindoles.

Merging the EHRs with big data analytics (BDA) capabilities enable healthcare stakeholders to provide effective and efficient treatments for chronic diseases. Though there are huge opportunities and efforts that exist in the deployment of EMRs and the development of BDA, there are challenges in addressing resources and organizational capabilities that are required to achieve the competitive advantage and sustainability of EHRs and BDA. The resource-based view (RBV), information system (IS), and non- IS theories should be extended to examine organizational capabilities and resources which are required for successful data analytics in the healthcare industries. The main purpose of this study is to develop a conceptual framework for the development of healthcare BDA capabilities based on past works so that researchers can extend. The research question was formulated for the search strategy as a research methodology. The study selection was made at the end. Based on the study selection, the conceptual framework for the development of BDA capabilities in the healthcare settings was formulated. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=EHR" title="EHR">EHR</a>, <a href="https://publications.waset.org/abstracts/search?q=EMR" title=" EMR"> EMR</a>, <a href="https://publications.waset.org/abstracts/search?q=Big%20data" title=" Big data"> Big data</a>, <a href="https://publications.waset.org/abstracts/search?q=Big%20data%20analytics" title=" Big data analytics"> Big data analytics</a>, <a href="https://publications.waset.org/abstracts/search?q=resource-based%20view" title=" resource-based view"> resource-based view</a> </p> <a href="https://publications.waset.org/abstracts/119580/deployment-of-electronic-healthcare-records-and-development-of-big-data-analytics-capabilities-in-the-healthcare-industry-a-systematic-literature-review" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/119580.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">131</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">35</span> Volarization of Sugarcane Bagasse: The Effect of Alkali Concentration, Soaking Time and Temperature on Fibre Yield</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Tamrat%20Tesfaye">Tamrat Tesfaye</a>, <a href="https://publications.waset.org/abstracts/search?q=Tilahun%20Seyoum"> Tilahun Seyoum</a>, <a href="https://publications.waset.org/abstracts/search?q=K.%20Shabaridharan"> K.

Since we design our structures economically for the maximum actions expected in the life of structures they go beyond their elastic limit, in need of nonlinear analysis. In this paper conventional pushover analysis (nonlinear static analysis) is used for the performance assessment of the case study Reinforced Concrete (RC) Frame building located in Addis Ababa City, Ethiopia where proposed peak ground acceleration value by RADIUS 1999 project and others is more than twice as of EBCS-8:1995 (RADIUS 1999 project) by taking critical planar frame. Fiber beam-column model is used to control material nonlinearity with tension stiffening effect. The reliability of the fiber model and validation of software outputs are checked under verification chapter. Therefore, the aim of this paper is to propose a way for structural performance assessment of existing reinforced concrete frame buildings as well as design check. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=seismic" title="seismic">seismic</a>, <a href="https://publications.waset.org/abstracts/search?q=performance" title=" performance"> performance</a>, <a href="https://publications.waset.org/abstracts/search?q=fiber%20model" title=" fiber model"> fiber model</a>, <a href="https://publications.waset.org/abstracts/search?q=tension%20stiffening" title=" tension stiffening"> tension stiffening</a>, <a href="https://publications.waset.org/abstracts/search?q=reinforced%20concrete" title=" reinforced concrete"> reinforced concrete</a> </p> <a href="https://publications.waset.org/abstracts/178786/fiber-based-pushover-analysis-of-reinforced-concrete-frame" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/178786.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">77</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">31</span> Shades of Memory, Echoes of Despair: Exploring Melancholy in Modern Amharic Novels</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Dawit%20%20Dibekulu">Dawit Dibekulu</a>, <a href="https://publications.waset.org/abstracts/search?q=Tesfaye%20Dagnew"> Tesfaye Dagnew</a>, <a href="https://publications.waset.org/abstracts/search?q=Tesfamaryam%20G.%20Meskel"> Tesfamaryam G.

Employing a psychoanalytic lens focused on Freud and Klein's theories of mourning and melancholia, we explore the psychological depths of characters ravaged by grief. Through an interpretive paradigm and descriptive research design, we unpack the intricate tapestry of the novel, revealing how love's ashes morph into melancholic despair. The loss of loved ones, be it sudden death or betrayal, casts long shadows on the characters' souls, distorting their behavior and twisting their narratives. Altered thoughts, self-blame, and paralyzing yearning become their companions, weaving a tragic dance of longing and despair. ‘Yäqənat Zār’ serves as a powerful testament to the transformative power of storytelling, allowing us to navigate the labyrinthine paths of melancholia and gain a glimpse into the Ethiopian soul grappling with loss. This study not only sheds light on the individual's struggle with sadness but also illuminates the cultural fabric of grief and melancholia intricately woven into Ethiopian society. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=melancholy" title="melancholy">melancholy</a>, <a href="https://publications.waset.org/abstracts/search?q=loss" title=" loss"> loss</a>, <a href="https://publications.waset.org/abstracts/search?q=psychoanalysis" title=" psychoanalysis"> psychoanalysis</a>, <a href="https://publications.waset.org/abstracts/search?q=grief" title=" grief"> grief</a>, <a href="https://publications.waset.org/abstracts/search?q=identity" title=" identity"> identity</a> </p> <a href="https://publications.waset.org/abstracts/181870/shades-of-memory-echoes-of-despair-exploring-melancholy-in-modern-amharic-novels" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/181870.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">64</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">30</span> Analysis of the Impact of Climate Change on Maize (Zea Mays) Yield in Central Ethiopia</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Takele%20Nemomsa">Takele Nemomsa</a>, <a href="https://publications.waset.org/abstracts/search?q=Girma%20Mamo"> Girma Mamo</a>, <a href="https://publications.waset.org/abstracts/search?q=Tesfaye%20Balemi"> Tesfaye Balemi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Climate change refers to a change in the state of the climate that can be identified (e.g. using statistical tests) by changes in the mean and/or variance of its properties and that persists for an extended period, typically decades or longer. In Ethiopia; Maize production in relation to climate change at regional and sub- regional scales have not been studied in detail. Thus, this study was aimed to analyse the impact of climate change on maize yield in Ambo Districts, Central Ethiopia. To this effect, weather data, soil data and maize experimental data for Arganne hybrid were used. APSIM software was used to investigate the response of maize (Zea mays) yield to different agronomic management practices using current and future (2020s–2080s) climate data. The climate change projections data which were downscaled using SDSM were used as input of climate data for the impact analysis. Compared to agronomic practices the impact of climate change on Arganne in Central Ethiopia is minute. However, within 2020s-2080s in Ambo area; the yield of Arganne hybrid is projected to reduce by 1.06% to 2.02%, and in 2050s it is projected to reduce by 1.56 While in 2080s; it is projected to increase by 1.03% to 2.07%. Thus, to adapt to the changing climate; farmers should consider increasing plant density and fertilizer rate per hectare. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=APSIM" title="APSIM">APSIM</a>, <a href="https://publications.waset.org/abstracts/search?q=downscaling" title=" downscaling"> downscaling</a>, <a href="https://publications.waset.org/abstracts/search?q=response" title=" response"> response</a>, <a href="https://publications.waset.org/abstracts/search?q=SDSM" title=" SDSM "> SDSM </a> </p> <a href="https://publications.waset.org/abstracts/49392/analysis-of-the-impact-of-climate-change-on-maize-zea-mays-yield-in-central-ethiopia" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/49392.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">383</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">29</span> Effectiveness of Reinforcement Learning (RL) for Autonomous Energy Management Solutions</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Tesfaye%20Mengistu">Tesfaye Mengistu</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This thesis aims to investigate the effectiveness of Reinforcement Learning (RL) for Autonomous Energy Management solutions. The study explores the potential of Model Free RL approaches, such as Monte Carlo RL and Q-learning, to improve energy management by autonomously adjusting energy management strategies to maximize efficiency. The research investigates the implementation of RL algorithms for optimizing energy consumption in a single-agent environment. The focus is on developing a framework for the implementation of RL algorithms, highlighting the importance of RL for enabling autonomous systems to adapt quickly to changing conditions and make decisions based on previous experiences. Moreover, the paper proposes RL as a novel energy management solution to address nations' CO2 emission goals. Reinforcement learning algorithms are well-suited to solving problems with sequential decision-making patterns and can provide accurate and immediate outputs to ease the planning and decision-making process. This research provides insights into the challenges and opportunities of using RL for energy management solutions and recommends further studies to explore its full potential. In conclusion, this study provides valuable insights into how RL can be used to improve the efficiency of energy management systems and supports the use of RL as a promising approach for developing autonomous energy management solutions in residential buildings. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=artificial%20intelligence" title="artificial intelligence">artificial intelligence</a>, <a href="https://publications.waset.org/abstracts/search?q=reinforcement%20learning" title=" reinforcement learning"> reinforcement learning</a>, <a href="https://publications.waset.org/abstracts/search?q=monte%20carlo" title=" monte carlo"> monte carlo</a>, <a href="https://publications.waset.org/abstracts/search?q=energy%20management" title=" energy management"> energy management</a>, <a href="https://publications.waset.org/abstracts/search?q=CO2%20emission" title=" CO2 emission"> CO2 emission</a> </p> <a href="https://publications.waset.org/abstracts/167464/effectiveness-of-reinforcement-learning-rl-for-autonomous-energy-management-solutions" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/167464.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">83</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">28</span> Methanolic Extract of the Exudates of Aloe Otallensis and Its Effect on Leishmania Donovani Parasite</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Zerihun%20Tesfaye%20Nigusse">Zerihun Tesfaye Nigusse</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Objective: This study evaluates the antileishmanial activity of the methanolic extract of Aloe otallensis (A. otallensis) on the promastigote stage of Leishmaniadonovani (L. donovani) as compared to standard drugs and to screen its phytochemical constituents.

The result was compared to standard drugs of sodium stibogluconate, milfostin and paramomycin. Results: The extract has good antileishmanial activity with an IC50 of 0.123 0 μg/mL on L. donovani (AM 563). The experimental data showed that relatively, it had better activity than paramomycin and milfostin but less activity than sodium stibogluconate. The data analyses were done by GraphPad Prism version 5 software after it was read by an ELISA reader at the wavelength of 650 nm. The phytochemical screening of the exudates of A. otallensis showed the presence of phenol, alkaloid and saponin. Conclusions: The methanol extract of the exudates of A.otallensishas a good anti- leishmaniasis activity and this may be attributed to phenol, alkaloid and saponin present in the plant. But it needs further analysis for the conformation of which constituent presents in high concentration to know which one has the strongest effect. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=anti%20leshimaniasis" title="anti leshimaniasis">anti leshimaniasis</a>, <a href="https://publications.waset.org/abstracts/search?q=aloe%20otallensis" title=" aloe otallensis"> aloe otallensis</a>, <a href="https://publications.waset.org/abstracts/search?q=leshimania%20ethiopica" title=" leshimania ethiopica"> leshimania ethiopica</a>, <a href="https://publications.waset.org/abstracts/search?q=IC50" title=" IC50"> IC50</a> </p> <a href="https://publications.waset.org/abstracts/188744/methanolic-extract-of-the-exudates-of-aloe-otallensis-and-its-effect-on-leishmania-donovani-parasite" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/188744.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">40</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">27</span> The Role of Formal and Informal Institutions in Water Governance in the Central Rift Valley of Ethiopia</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Endalew%20Jibat">Endalew Jibat</a>, <a href="https://publications.waset.org/abstracts/search?q=Feyera%20Senbeta"> Feyera Senbeta</a>, <a href="https://publications.waset.org/abstracts/search?q=Tesfaye%20Zeleke"> Tesfaye Zeleke</a>, <a href="https://publications.waset.org/abstracts/search?q=Fitsum%20Hagos"> Fitsum Hagos</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Institutions can play a key role in coordinating how natural resources are effectively used without over-exploitation. Institutions are the laws, policies, and organizational arrangements that permit, forbid or regulate human action. The aim of this study was to look into the roles of formal and informal institutions, as well as their interactions, in water resource governance in Ethiopia's Central Rift Valley (CRV), where water scarcity is a concern. Key informant interviews, group discussions, in depth-interview, and secondary data sources were used to generate relevant data. The study revealed that formal and informal institutions were involved in water resource governance in the study area. However, the influence of informal institutions on formal institutions or vice versa is trivial to change the action of water users. Lack of clear roles and responsibilities of actors, weak capacity and lack of meaningful decentralization and participation of key actors in policy development, lack of synergy and incongruence between formal and informal institutions, and absence of enforcement mechanisms including incentives are attributed to inefficient use of water resources in the CRV. Enhancing the interplay of formal and informal institutions in the water resource policy development and meaningful decentralization and key stakeholders' engagement is recommended for sustainable water use. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=institutions" title="institutions">institutions</a>, <a href="https://publications.waset.org/abstracts/search?q=governance" title=" governance"> governance</a>, <a href="https://publications.waset.org/abstracts/search?q=institutional%20interplay" title=" institutional interplay"> institutional interplay</a>, <a href="https://publications.waset.org/abstracts/search?q=water%20users" title=" water users"> water users</a> </p> <a href="https://publications.waset.org/abstracts/155986/the-role-of-formal-and-informal-institutions-in-water-governance-in-the-central-rift-valley-of-ethiopia" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/155986.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">178</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">26</span> Dynamics of Museum Visitors’ Experiences Studies: A Bibliometric Analysis</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Tesfaye%20Fentaw%20Nigatu">Tesfaye Fentaw Nigatu</a>, <a href="https://publications.waset.org/abstracts/search?q=Alexander%20Trupp"> Alexander Trupp</a>, <a href="https://publications.waset.org/abstracts/search?q=Teh%20Pek%20Yen"> Teh Pek Yen</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Research on museums and the experiences of visitors has flourished in recent years, especially after museums became centers of edutainment beyond preserving heritage resources. This paper aims to comprehensively understand the changes, continuities, and future research development directions of museum visitors’ experiences. To identify current research trends, the paper summarizes and analyses research article publications from 1986 to 2023 on museum visitors' experiences. Bibliometric analysis software VOSviewer and Harzing POP (Publish or Perish) were used to analyze 407 academic articles. The articles were generated from the Scopus database. The study attempted to map new insights for future scholars and academics to expand the scope of museum visitors’ experience studies by analyzing keywords, citation patterns, influential articles in the field, publication trends, collaborations between authors, institutions, and clusters of highly cited articles.

Seeds of 12 Lentil accessions were grown at laboratory (Petri dish) condition with different levels of salinity (0, 2, 4, and 8 dSm-1 NaCl) for 4 weeks. The experimental design was completely randomized design (CRD) in factorial combination with three replications. Data analysis was carried out using SAS software. Average germination time, germination percentage, seedling shoot and root traits, seedling shoot and root weight were evaluated. The two way ANOVA for varieties revealed statistically significant variation among lentil accession, NaCl level and their interactions (p<0.001) with respect to the entire parameters. It was found that salt stress significantly delays germination rate and decreases germination percentage, shoot and root length, seedling shoot and root weight of lentil accessions. The degree of decrement varied with accessions and salinity levels. Accessions 36120, 9235 and 36004 were better salt tolerant than the other accessions. As the result, it is recommended to be used as a genetic resource for the development of lentil accession and other very salt sensitive crop with improved germination under salt stress condition. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=accession" title="accession">accession</a>, <a href="https://publications.waset.org/abstracts/search?q=germination" title=" germination"> germination</a>, <a href="https://publications.waset.org/abstracts/search?q=lentil" title=" lentil"> lentil</a>, <a href="https://publications.waset.org/abstracts/search?q=NaCl" title=" NaCl"> NaCl</a>, <a href="https://publications.waset.org/abstracts/search?q=screening" title=" screening"> screening</a>, <a href="https://publications.waset.org/abstracts/search?q=seedling%20stage" title=" seedling stage"> seedling stage</a> </p> <a href="https://publications.waset.org/abstracts/29040/screening-some-accessions-of-lentil-lens-culinaris-m-for-salt-tolerance-at-germination-and-early-seedling-stage-in-eastern-ethiopia" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/29040.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">339</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">24</span> Constructing a Semi-Supervised Model for Network Intrusion Detection</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Tigabu%20Dagne%20Akal">Tigabu Dagne Akal</a> </p> <p class="card-text"><strong>Abstract:</strong></p> While advances in computer and communications technology have made the network ubiquitous, they have also rendered networked systems vulnerable to malicious attacks devised from a distance. These attacks or intrusions start with attackers infiltrating a network through a vulnerable host and then launching further attacks on the local network or Intranet. Nowadays, system administrators and network professionals can attempt to prevent such attacks by developing intrusion detection tools and systems using data mining technology. In this study, the experiments were conducted following the Knowledge Discovery in Database Process Model. The Knowledge Discovery in Database Process Model starts from selection of the datasets. The dataset used in this study has been taken from Massachusetts Institute of Technology Lincoln Laboratory. After taking the data, it has been pre-processed. The major pre-processing activities include fill in missed values, remove outliers; resolve inconsistencies, integration of data that contains both labelled and unlabelled datasets, dimensionality reduction, size reduction and data transformation activity like discretization tasks were done for this study. A total of 21,533 intrusion records are used for training the models. For validating the performance of the selected model a separate 3,397 records are used as a testing set. For building a predictive model for intrusion detection J48 decision tree and the Naïve Bayes algorithms have been tested as a classification approach for both with and without feature selection approaches. The model that was created using 10-fold cross validation using the J48 decision tree algorithm with the default parameter values showed the best classification accuracy. The model has a prediction accuracy of 96.11% on the training datasets and 93.2% on the test dataset to classify the new instances as normal, DOS, U2R, R2L and probe classes. The findings of this study have shown that the data mining methods generates interesting rules that are crucial for intrusion detection and prevention in the networking industry. Future research directions are forwarded to come up an applicable system in the area of the study. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=intrusion%20detection" title="intrusion detection">intrusion detection</a>, <a href="https://publications.waset.org/abstracts/search?q=data%20mining" title=" data mining"> data mining</a>, <a href="https://publications.waset.org/abstracts/search?q=computer%20science" title=" computer science"> computer science</a>, <a href="https://publications.waset.org/abstracts/search?q=data%20mining" title=" data mining"> data mining</a> </p> <a href="https://publications.waset.org/abstracts/3289/constructing-a-semi-supervised-model-for-network-intrusion-detection" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/3289.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">296</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">23</span> The Application of AI in Developing Assistive Technologies for Non-Verbal Individuals with Autism</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ferah%20Tesfaye%20Admasu">Ferah Tesfaye Admasu</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Autism Spectrum Disorder (ASD) often presents significant communication challenges, particularly for non-verbal individuals who struggle to express their needs and emotions effectively. Assistive technologies (AT) have emerged as vital tools in enhancing communication abilities for this population. Recent advancements in artificial intelligence (AI) hold the potential to revolutionize the design and functionality of these technologies. This study explores the application of AI in developing intelligent, adaptive, and user-centered assistive technologies for non-verbal individuals with autism. Through a review of current AI-driven tools, including speech-generating devices, predictive text systems, and emotion-recognition software, this research investigates how AI can bridge communication gaps, improve engagement, and support independence. Machine learning algorithms, natural language processing (NLP), and facial recognition technologies are examined as core components in creating more personalized and responsive communication aids. The study also discusses the challenges and ethical considerations involved in deploying AI-based AT, such as data privacy and the risk of over-reliance on technology. Findings suggest that integrating AI into assistive technologies can significantly enhance the quality of life for non-verbal individuals with autism, providing them with greater opportunities for social interaction and participation in daily activities. However, continued research and development are needed to ensure these technologies are accessible, affordable, and culturally sensitive. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=artificial%20intelligence" title="artificial intelligence">artificial intelligence</a>, <a href="https://publications.waset.org/abstracts/search?q=autism%20spectrum%20disorder" title=" autism spectrum disorder"> autism spectrum disorder</a>, <a href="https://publications.waset.org/abstracts/search?q=non-verbal%20communication" title=" non-verbal communication"> non-verbal communication</a>, <a href="https://publications.waset.org/abstracts/search?q=assistive%20technology" title=" assistive technology"> assistive technology</a>, <a href="https://publications.waset.org/abstracts/search?q=machine%20learning" title=" machine learning"> machine learning</a> </p> <a href="https://publications.waset.org/abstracts/192336/the-application-of-ai-in-developing-assistive-technologies-for-non-verbal-individuals-with-autism" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/192336.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">19</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">22</span> Effects of Drying Method and Seed Priming Duration on Coffee Seed and Seedling Quality</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Taju%20Mohammednur">Taju Mohammednur</a>, <a href="https://publications.waset.org/abstracts/search?q=Tesfaye%20Megersa"> Tesfaye Megersa</a>, <a href="https://publications.waset.org/abstracts/search?q=Karta%20Kaske"> Karta Kaske</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Coffee is an economically important cash crop in Ethiopia. However, the conditions under which coffee seeds are dried and processed significantly affect the seedling quality and productivity. The objective of this study was to evaluate the effect of pre-sowing treatments and drying methods on the physiological quality of coffee seeds and seedlings. The study included two coffee varieties (74110, 75227), two drying conditions (under-shade drying room, open sun), and five durations of seed hydro priming (6, 8, 18, 24 hours, and an untreated control). Factorial combinations of the three factors were laid out in a Completely Randomized Design of three replications. Results indicated that the highest germination percentage (91%), emergence rate (90%), and seedling vigor index-I (2236 cm %) were recorded for seeds dried under-shade drying room. In contrast, the lowest values of germination percentage, emergence rate, and vigor index were observed for seeds dried under open sun. There was a significant difference in seed germination based on hydro priming time, with the highest germination percentage (83%) recorded for seeds soaked for 6 hours, followed by 24 hours (83%). The lowest germination percentage (77%) was recorded for un-soaked seeds. In conclusion, drying seeds under shade is better for coffee seed quality, and hydro priming has improved seedling vigor. However, further investigation into seed priming methods and preservation techniques for primed seeds is necessary to improve coffee seed quality. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=coffee" title="coffee">coffee</a>, <a href="https://publications.waset.org/abstracts/search?q=germination" title=" germination"> germination</a>, <a href="https://publications.waset.org/abstracts/search?q=seed%20drying" title=" seed drying"> seed drying</a>, <a href="https://publications.waset.org/abstracts/search?q=seed%20longevity" title=" seed longevity"> seed longevity</a>, <a href="https://publications.waset.org/abstracts/search?q=seed%20priming" title=" seed priming"> seed priming</a> </p> <a href="https://publications.waset.org/abstracts/191107/effects-of-drying-method-and-seed-priming-duration-on-coffee-seed-and-seedling-quality" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/191107.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">28</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">21</span> Comparison of Sign Language Skill and Academic Achievement of Deaf Students in Special and Inclusive Primary Schools of South Nation Nationalities People Region, Ethiopia</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Tesfaye%20Basha">Tesfaye Basha</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The purpose of this study was to examine the sign language and academic achievement of deaf students in special and inclusive primary schools of Southern Ethiopia. The study used a mixed-method to collect varied data.

For quantitative (n=70) deaf students and for qualitative data collection, 16 participants were involved. The finding revealed that the limitation of sign language is a problem in signing and academic achievements. This displays that schools are not linguistically rich to enable sign language achievement for deaf students. Moreover, the finding revealed that the contribution of Total Communication in the growth of natural sign language for deaf students was unsatisfactory. The results also indicated that special schools of deaf students performed better sign language skills and academic achievement than inclusive schools. In addition, the findings revealed that high signed skill group showed higher academic achievement than the low skill group. This displayed that sign language skill is highly associated with academic achievement. In addition, to qualify deaf students in sign language and academics, teacher institutions must produce competent teachers on how to teach deaf students with sign language and literacy skills. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=academic%20achievement" title="academic achievement">academic achievement</a>, <a href="https://publications.waset.org/abstracts/search?q=inclusive%20school" title=" inclusive school"> inclusive school</a>, <a href="https://publications.waset.org/abstracts/search?q=sign%20language" title=" sign language"> sign language</a>, <a href="https://publications.waset.org/abstracts/search?q=signed%20Amharic" title=" signed Amharic"> signed Amharic</a>, <a href="https://publications.waset.org/abstracts/search?q=signed%20English" title=" signed English"> signed English</a>, <a href="https://publications.waset.org/abstracts/search?q=special%20school" title=" special school"> special school</a>, <a href="https://publications.waset.org/abstracts/search?q=total%20communication" title=" total communication"> total communication</a> </p> <a href="https://publications.waset.org/abstracts/130014/comparison-of-sign-language-skill-and-academic-achievement-of-deaf-students-in-special-and-inclusive-primary-schools-of-south-nation-nationalities-people-region-ethiopia" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/130014.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">133</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">20</span> A Review on Valorisation of Chicken Feathers: Current Status and Future Prospects</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Tamrat%20Tesfaye">Tamrat Tesfaye</a>, <a href="https://publications.waset.org/abstracts/search?q=Bruce%20Sithole"> Bruce Sithole</a>, <a href="https://publications.waset.org/abstracts/search?q=Deresh%20Ramjugernath"> Deresh Ramjugernath</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Worldwide, the poultry–processing industry generates large quantities of feather by-products that amount to 40 billion kilograms annually. The feathers are considered wastes although small amounts are often processed into valuable products such as feather meal and fertilizers. The remaining waste is disposed of by incineration or by burial in controlled landfills. Improper disposal of these biological wastes contributes to environmental damage and transmission of diseases. Economic pressures, environmental pressures, increasing interest in using renewable and sustainable raw materials, and the need to decrease reliance on non-renewable petroleum resources behove the industry to find better ways of dealing with waste feathers. A closer look at the structure and composition of feathers shows that the whole part of a chicken feather (rachis and barb) can be used as a source of a pure structural protein called keratin which can be exploited for conversion into a number of high-value bio products. Additionally, a number of technologies can be used to convert other biological components of feathers into high value added products. Thus, conversion of the waste into valuable products can make feathers an attractive raw material for the production of bio products. In this review, possible applications of chicken feathers in a variety of technologies and products are discussed. Thus, using waste feathers as a valuable resource can help the poultry industry to dispose of the waste feathers in an environmentally sustainable manner that also generates extra income for the industry. Their valorisation can result in their sustainable conversion into high-value materials and products on the proviso of existence or development of cost-effective technologies for converting this waste into the useful products. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=biodegradable%20product" title="biodegradable product">biodegradable product</a>, <a href="https://publications.waset.org/abstracts/search?q=keratin" title=" keratin"> keratin</a>, <a href="https://publications.waset.org/abstracts/search?q=poultry%20waste" title=" poultry waste"> poultry waste</a>, <a href="https://publications.waset.org/abstracts/search?q=feathers" title=" feathers"> feathers</a>, <a href="https://publications.waset.org/abstracts/search?q=valorisation" title=" valorisation"> valorisation</a> </p> <a href="https://publications.waset.org/abstracts/45685/a-review-on-valorisation-of-chicken-feathers-current-status-and-future-prospects" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/45685.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">296</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">19</span> Determinants of Household Food Security in Addis Ababa City Administration</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Estibe%20Dagne%20Mekonnen">Estibe Dagne Mekonnen</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In recent years, the prevalence of undernourishment was 30 percent for sub-Saharan Africa, compared with 16 percent for Asia and the Pacific (Ali, 2011). In Ethiopia, almost 40 percent of the total population in the country and 57 percent of Addis Ababa population lives below the international poverty line of US$ 1.25 per day (UNICEF, 2009). This study aims to analyze the determinant of household food secrity in Addis Ababa city administration. Primary data were collected from a survey of 256 households in the selected sub-city, namely Addis Ketema, Arada, and Kolfe Keranio, in the year 2022. Both Purposive and multi-stage cluster random sampling procedures were employed to select study areas and respondents. Descriptive statistics and order logistic regression model were used to test the formulated hypotheses. The result reveals that out of the total sampled households, 25% them were food secured, 13% were mildly food insecure, 26% were moderately food insecure and 36% were severely food insecure. The study indicates that household family size, house ownership, household income, household food source, household asset possession, household awareness on inflation, household access to social protection program, household access to credit and saving and household access to training and supervision on food security have a positive and significant effect on the likelihood of household food security status. However, marital status of household head, employment sector of household head, dependency ratio and household’s nonfood expenditure has a negative and significant influence on household food security status. The study finally suggests that the government in collaboration with financial institutions and NGO should work on sustaining household food security by creating awareness, providing credit, facilitate rural-urban linkage between producer and consumer and work on urban infrastructure improvement. Moreover, the governments also work closely and monitor consumer good suppliers, if possible find a way to subsidize consumable goods to more insecure households and make them to be food secured. Last but not least, keeping this country’s peace will play a crucial role to sustain food security. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=determinants" title="determinants">determinants</a>, <a href="https://publications.waset.org/abstracts/search?q=household" title=" household"> household</a>, <a href="https://publications.waset.org/abstracts/search?q=food%20security" title=" food security"> food security</a>, <a href="https://publications.waset.org/abstracts/search?q=order%20logit%20model" title=" order logit model"> order logit model</a>, <a href="https://publications.waset.org/abstracts/search?q=Addis%20Ababa" title=" Addis Ababa"> Addis Ababa</a> </p> <a href="https://publications.waset.org/abstracts/179572/determinants-of-household-food-security-in-addis-ababa-city-administration" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/179572.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">73</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">18</span> Prediction of California Bearing Ratio of a Black Cotton Soil Stabilized with Waste Glass and Eggshell Powder using Artificial Neural Network</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Biruhi%20Tesfaye">Biruhi Tesfaye</a>, <a href="https://publications.waset.org/abstracts/search?q=Avinash%20M.%20Potdar"> Avinash M.

Hence advanced prediction of CBR plays a significant role as it is applicable In pavement design. The prediction of CBR of treated soil was executed by Artificial Neural Networks (ANNs) which is a Computational tool based on the properties of the biological neural system. To observe CBR values, combined eggshell and waste glass was added to soil as 4, 8, 12, and 16 % of the weights of the soil samples. Accordingly, the laboratory related tests were conducted to get the required best model. The maximum CBR value found at 5.8 at 8 % of eggshell waste glass powder addition. The model was developed using CBR as an output layer variable. CBR was considered as a function of the joint effect of liquid limit, plastic limit, and plastic index, optimum moisture content and maximum dry density. The best model that has been found was ANN with 5, 6 and 1 neurons in the input, hidden and output layer correspondingly. The performance of selected ANN has been 0.99996, 4.44E-05, 0.00353 and 0.0067 which are correlation coefficient (R), mean square error (MSE), mean absolute error (MAE) and root mean square error (RMSE) respectively. The research presented or summarized above throws light on future scope on stabilization with waste glass combined with different percentages of eggshell that leads to the economical design of CBR acceptable to pavement sub-base or base, as desired. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=CBR" title="CBR">CBR</a>, <a href="https://publications.waset.org/abstracts/search?q=artificial%20neural%20network" title=" artificial neural network"> artificial neural network</a>, <a href="https://publications.waset.org/abstracts/search?q=liquid%20limit" title=" liquid limit"> liquid limit</a>, <a href="https://publications.waset.org/abstracts/search?q=plastic%20limit" title=" plastic limit"> plastic limit</a>, <a href="https://publications.waset.org/abstracts/search?q=maximum%20dry%20density" title=" maximum dry density"> maximum dry density</a>, <a href="https://publications.waset.org/abstracts/search?q=OMC" title=" OMC"> OMC</a> </p> <a href="https://publications.waset.org/abstracts/139867/prediction-of-california-bearing-ratio-of-a-black-cotton-soil-stabilized-with-waste-glass-and-eggshell-powder-using-artificial-neural-network" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/139867.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">190</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">17</span> Intellectual Property and SMEs in the Baltic Sea Region: A Comparative Study on the Use of the Utility Model Protection</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Christina%20Wainikka">Christina Wainikka</a>, <a href="https://publications.waset.org/abstracts/search?q=Besrat%20Tesfaye"> Besrat Tesfaye</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Several of the countries in the Baltic Sea region are ranked high in international innovations rankings, such as the Global Innovation Index and European Innovation Scoreboard. There are however some concerns in the performance of different countries. For example, there is a widely spread notion about “The Swedish Paradox”. Sweden is ranked high due to investments in R&D and patent activity, but the outcome is not as high as could be expected. SMEs in Sweden are also below EU average when it comes to registering intellectual property rights such as patents and trademarks. This study is concentrating on the protection of utility model. This intellectual property right does not exist in Sweden, but in for example Finland and Germany. The utility model protection is sometimes referred to as a “patent light” since it is easier to obtain than the patent protection but at the same time does cover technical solutions. In examining statistics on patent activities and activities in registering utility models it is clear that utility model protection is scarcely used in the countries that have the protection. In Germany 10 577 applications were made in 2021. In Finland there were 259 applications made in 2021. This can be compared with patent applications that were 58 568 in Germany in 2021 and 1 662 in Finland in 2021. In Sweden there has never been a protection for utility models. The only protection for technical solutions is patents and business secrets. The threshold for obtaining a patent is high, due to the legal requirements and the costs. The patent protection is there for often not chosen by SMEs in Sweden. This study examines whether the protection of utility models in other countries in the Baltic region provide SMEs in these countries with better options to protect their innovations. The legal methodology is comparative law. In order to study the effects of the legal differences statistics are examined and interviews done with SMEs from different industries. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=baltic%20sea%20region" title="baltic sea region">baltic sea region</a>, <a href="https://publications.waset.org/abstracts/search?q=comparative%20law" title=" comparative law"> comparative law</a>, <a href="https://publications.waset.org/abstracts/search?q=SME" title=" SME"> SME</a>, <a href="https://publications.waset.org/abstracts/search?q=utility%20model" title=" utility model"> utility model</a> </p> <a href="https://publications.waset.org/abstracts/149097/intellectual-property-and-smes-in-the-baltic-sea-region-a-comparative-study-on-the-use-of-the-utility-model-protection" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/149097.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">114</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">16</span> Food and Nutritional Security in the Context of Climate Change in Ethiopia: Using Household Panel Data</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Aemro%20Tazeze%20Terefe">Aemro Tazeze Terefe</a>, <a href="https://publications.waset.org/abstracts/search?q=Mengistu%20K.%20Aredo"> Mengistu K.

Tesfaye</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Climate-induced shocks have been shown to reduce agricultural production and cause fluctuation in output in developing countries. When livelihoods depend on rain-fed agriculture, climate-induced shocks translate into consumption shocks. Despite the substantial improvements in household consumption, climate-induced shocks, and other factors adversely affect consumption dynamics at the household level in Ethiopia. Therefore, household consumption dynamics in the context of climate-induced shocks help to guide resilience capacity and establish appropriate interventions and programs. The research employed three-round panel data based on the Ethiopian Socioeconomic Survey with spatial rainfall data to define unique measures of rainfall variability. The linear dynamic panel model results show that the lagged value of consumption, market shocks, and rainfall variability positively affected consumption dynamics. In contrast, production shocks, temperature, and amount of rainfall had a negative relationship. Coping strategies mitigate adverse climate-induced shocks on consumption aftershocks that smooth consumption over time. Support to increase the resilience capacity of households can involve efforts to make existing livelihoods and forms of production or reductions in the vulnerability of households. Therefore, government interventions are mandatory for asset accumulation agendas that support household coping strategies and respond to shocks. In addition, the dynamic linkage between consumption and significant socioeconomic and institutional factors should be taken into account to minimize the effect of climate-induced shocks on consumption dynamics. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=climate%20shock" title="climate shock">climate shock</a>, <a
