The study analyzed changes in urban green space coverage over the past 20 years in two rapidly urbanizing cities in Ethiopia, Debre Berhan and Debre Markos, using GIS and remote sensing. The researchers used Landsat 5 and 8 data with a spatial resolution of 30 m to determine different land use and land cover classes, including urban green spaces, barren and croplands, built-up areas, and water bodies. The classification accuracy ranged between 90% and 91.4%, with a Kappa Statistic of 0.85 to 0.88. The results showed that both cities experienced significant decreases in vegetation cover in their urban cores between 2000 and 2020, with radical changes observed from green spaces and croplands to built-up areas. In Debre Berhan, barren and croplands decreased by 32.96%, while built-up and green spaces increased by 357.9% and 37.4%, respectively, in 2020. In Debre Markos, built-up areas increased by 224.2%, while green spaces and barren and croplands decreased by 41% and 5.71%, respectively. The spatial structure of cities and planning policies were noticed as the major factors for big green cover change. Thus it has an implication for other rapidly urbanized cities in Africa and Asia. Overall, rapid urbanization threatens green spaces and agricultural areas, highlighting the need for ecological-based spatial planning in rapidly urbanizing cities. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=green%20space%20coverage" title="green space coverage">green space coverage</a>, <a href="https://publications.waset.org/abstracts/search?q=GIS%20and%20remote%20sensing" title=" GIS and remote sensing"> GIS and remote sensing</a>, <a href="https://publications.waset.org/abstracts/search?q=Landsat" title=" Landsat"> Landsat</a>, <a href="https://publications.waset.org/abstracts/search?q=LULC" title=" LULC"> LULC</a>, <a href="https://publications.waset.org/abstracts/search?q=Ethiopia" title=" Ethiopia"> Ethiopia</a> </p> <a href="https://publications.waset.org/abstracts/181113/monitoring-urban-green-space-cover-change-using-gis-and-remote-sensing-in-two-rapidly-urbanizing-cities-debre-berhan-and-debre-markos-ethiopia" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/181113.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">56</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> Affordable Housing and Economic Sustainability: The Case of the Poorest of the Poor Housing in Debre Markos City</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Michael%20Menberu">Michael Menberu</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Housing affordability is a crucial policy objective. Incorporating economic sustainability in affordable housing in the development of the poorest of the poor's housing programs has become a major concern. This paper examines the affordability and economic sustainability of the poorest of the poor affordable housing in Debre Markos city. To address this, this study uses both quantitative and qualitative methods, Using a questionnaire survey, Interviews, field observation, household survey, and Pearson correlation analysis. The findings show that households in the expansion area have lower monthly incomes than in the past, but they are satisfied with the housing quality, rental pricing, and tenure security of their homes. This demonstrates in providing affordable housing for the poorest of the poor the location of the houses must be considered in order to have affordable and economically sustainable development. The findings show that housing is not truly affordable if it is in an inaccessible place with a long commute to work, high transportation expenditures, and land use that is homogeneous. Increasing the supply of affordable housing in accessible locations helps the poorest of the poor achieve multiple planning objectives: it reduces transportation costs, improves incomes, provides infrastructure, and reduces the distance to the work area. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=housing" title="housing">housing</a>, <a href="https://publications.waset.org/abstracts/search?q=affordable%20housing" title=" affordable housing"> affordable housing</a>, <a href="https://publications.waset.org/abstracts/search?q=economic%20sustainability" title=" economic sustainability"> economic sustainability</a>, <a href="https://publications.waset.org/abstracts/search?q=the%20poorest%20of%20the%20poor%20housing" title=" the poorest of the poor housing"> the poorest of the poor housing</a> </p> <a href="https://publications.waset.org/abstracts/186702/affordable-housing-and-economic-sustainability-the-case-of-the-poorest-of-the-poor-housing-in-debre-markos-city" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/186702.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">50</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> Rethinking Urban Green Space Quality and Planning Models from Users and Experts’ Perspective for Sustainable Development: The Case of Debre Berhan and Debre Markos Cities, Ethiopia</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Alemaw%20Kefale">Alemaw Kefale</a>, <a href="https://publications.waset.org/abstracts/search?q=Aramde%20Fetene"> Aramde Fetene</a>, <a href="https://publications.waset.org/abstracts/search?q=Hayal%20Desta"> Hayal Desta</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This study analyzed the users' and experts' views on the green space quality and planning models in Debre Berhan (DB) and Debre Markos (DM) cities in Ethiopia. A questionnaire survey was conducted on 350 park users (148 from DB and 202 from DM) to rate the accessibility, size, shape, vegetation cover, social and cultural context, conservation and heritage, community participation, attractiveness, comfort, safety, inclusiveness, and maintenance of green spaces using a Likert scale. A key informant interview was held with 13 experts in DB and 12 in DM. Descriptive statistics and tests of independence of variables using the chi-square test were done. A statistically significant association existed between the perception of green space quality attributes and users' occupation (χ² (160, N = 350) = 224.463, p < 0.001), age (χ² (128, N = 350) = 212.812, p < 0.001), gender (χ² (32, N = 350) = 68.443, p < 0.001), and education level (χ² (192, N = 350) = 293.396, p < 0.001). 61.7 % of park users were unsatisfied with the quality of urban green spaces. The users perceived dense vegetation cover as "good," with a mean value of 3.41, while the remaining were perceived as "medium with a mean value of 2.62 – 3.32". Only quantitative space standards are practiced as a green space planning model, while other models are unfamiliar and never used in either city. Therefore, experts need to be aware of and practice urban green models during urban planning to ensure that new developments include green spaces to accommodate the community's and the environment's needs. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=urban%20green%20space" title="urban green space">urban green space</a>, <a href="https://publications.waset.org/abstracts/search?q=quality" title=" quality"> quality</a>, <a href="https://publications.waset.org/abstracts/search?q=users%20and%20experts" title=" users and experts"> users and experts</a>, <a href="https://publications.waset.org/abstracts/search?q=green%20space%20planning%20models" title=" green space planning models"> green space planning models</a>, <a href="https://publications.waset.org/abstracts/search?q=Ethiopia" title=" Ethiopia"> Ethiopia</a> </p> <a href="https://publications.waset.org/abstracts/181281/rethinking-urban-green-space-quality-and-planning-models-from-users-and-experts-perspective-for-sustainable-development-the-case-of-debre-berhan-and-debre-markos-cities-ethiopia" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/181281.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">58</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> Implementation Of Evidence Based Nursing Practice And Associated Factors Among Nurses Working In Jimma Zone Public Hospitals, Southwest Ethiopia</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Dawit%20Hoyiso">Dawit Hoyiso</a>, <a href="https://publications.waset.org/abstracts/search?q=Abinet%20Arega"> Abinet Arega</a>, <a href="https://publications.waset.org/abstracts/search?q=Terefe%20Markos"> Terefe Markos</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Background: - In spite of all the various programs and strategies to promote the use of research finding there is still gap between theory and practice. Difference in outcomes, health inequalities, and poorly performing health service continue to present a challenge to all nurses. A number of studies from various countries have reported that nurses’ experience of evidence-based practice is low. In Ethiopia there is an information gap on the extent of evidence based nursing practice and its associated factors. Objective: - the study aims to assess the implementation of evidence based nursing practice and associated factors among nurses in Jimma zone public hospitals. Method: - Institution based cross-sectional study was conducted from March 1-30/2015. A total of 333 sampled nurses for quantitative and 8 in-depth interview of key informants were involved in the study. Semi-structured questionnaire was adapted from funk’s BARRIER scale and Friedman’s test. Multivariable Linear regression was used to determine significance of association between dependent and independent variables. Pretest was done on 17 nurses of Bedele hospital. Ethical issue was secured. Result:-Of 333 distributed questionnaires 302 were completed, giving 90.6% response rate. Of 302 participants 245 were involved in EBP activities to different level (from seldom to often). About forty five(18.4%) of the respondents had implemented evidence based practice to low level (sometimes), one hundred three (42 %) of respondents had implemented evidence based practice to medium level and ninety seven (39.6 %) of respondents had implemented evidence based practice to high level(often). The first greatest perceived barrier was setting characteristic (mean score=26.60±7.08). Knowledge about research evidence was positively associated with implementation of evidence based nursing practice (β=0.76, P=0.008). Similarly, Place where the respondent graduated was positively associated with implementation of evidence based nursing practice (β=2.270, P=0.047). Also availability of information resources was positively associated with implementation of evidence based practice (β=0.67, P= 0.006). Conclusion: -Even though larger portion of nurses in this study were involved in evidence-based practice whereas small number of participants had implemented frequently. Evidence-based nursing practice was positively associated with knowledge of research, place where respondents graduated, and the availability of information resources. Organizational factors were found to be the greatest perceived barrier. Intervention programs on awareness creation, training, resource provision, and curriculum issues to improve implementation of evidence based nursing practice by stakeholders are recommended. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=evidence%20based%20practice" title="evidence based practice">evidence based practice</a>, <a href="https://publications.waset.org/abstracts/search?q=nursing%20practice" title=" nursing practice"> nursing practice</a>, <a href="https://publications.waset.org/abstracts/search?q=research%20utilization" title=" research utilization"> research utilization</a>, <a href="https://publications.waset.org/abstracts/search?q=Ethiopia" title=" Ethiopia"> Ethiopia</a> </p> <a href="https://publications.waset.org/abstracts/165502/implementation-of-evidence-based-nursing-practice-and-associated-factors-among-nurses-working-in-jimma-zone-public-hospitals-southwest-ethiopia" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/165502.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">95</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> Building a Stochastic Simulation Model for Blue Crab Population Evolution in Antinioti Lagoon</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Nikolaos%20Simantiris">Nikolaos Simantiris</a>, <a href="https://publications.waset.org/abstracts/search?q=Markos%20Avlonitis"> Markos Avlonitis</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This work builds a simulation platform, modeling the spatial diffusion of the invasive species Callinectes sapidus (blue crab) as a random walk, incorporating also generation, fatality, and fishing rates modeling the time evolution of its population.

Hence, predictive data mining techniques can greatly benefit to analyze and discover new patterns from huge datasets like that of EDHS 2011 data. Objectives: The objective of this study is to build a predictive modeling for HIV testing and identify determinants of HIV testing for adults with age above fourteen years using data mining techniques. Methods: Cross-Industry Standard Process for Data Mining (CRISP-DM) was used to predict the model for HIV testing and explore association rules between HIV testing and the selected attributes among adult Ethiopians. Decision tree, Naïve-Bayes, logistic regression and artificial neural networks of data mining techniques were used to build the predictive models. Results: The target dataset contained 30,625 study participants; of which 16, 515 (53.9%) were women. Nearly two-fifth; 17,719 (58%), have never been tested for HIV while the rest 12,906 (42%) had been tested. Ethiopians with higher wealth index, higher educational level, belonging 20 to 29 years old, having no stigmatizing attitude towards HIV positive person, urban residents, having HIV related knowledge, information about family planning on mass media and knowing a place where to get testing for HIV showed an increased patterns with respect to HIV testing. Conclusion and Recommendation: Public health interventions should consider the identified determinants to promote people to get testing for HIV. <p class="card-text"><strong>Keywords:</strong> <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=HIV" title=" HIV"> HIV</a>, <a href="https://publications.waset.org/abstracts/search?q=testing" title=" testing"> testing</a>, <a href="https://publications.waset.org/abstracts/search?q=ethiopia" title=" ethiopia"> ethiopia</a> </p> <a href="https://publications.waset.org/abstracts/34140/human-immunodeficiency-virus-hiv-test-predictive-modeling-and-identify-determinants-of-hiv-testing-for-people-with-age-above-fourteen-years-in-ethiopia-using-data-mining-techniques-edhs-2011" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/34140.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">496</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">12</span> Design and Synthesis of Copper-Zeolite Composite for Antimicrobial Activity and Heavy Metal Removal From Waste Water</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Feleke%20Terefe%20Fanta">Feleke Terefe Fanta</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Background: The existence of heavy metals and coliform bacteria contaminants in aquatic system of Akaki river basin, a sub city of Addis Ababa, Ethiopia has become a public concern as human population increases and land development continues. Hence, it is the right time to design treatment technologies that can handle multiple pollutants. Results: In this study, we prepared a synthetic zeolites and copper doped zeolite composite adsorbents as cost effective and simple approach to simultaneously remove heavy metals and total coliforms from wastewater of Akaki river. The synthesized copper–zeolite X composite was obtained by ion exchange method of copper ions into zeolites frameworks. Iodine test, XRD, FTIR and autosorb IQ automated gas sorption analyzer were used to characterize the adsorbents. The mean concentrations of Cd, Cr, and Pb in untreated sample were 0.795, 0.654 and 0.7025 mg/L respectively. These concentrations decreased to Cd (0.005 mg/L), Cr (0.052 mg/L) and Pb (bellow detection limit, BDL) for sample treated with bare zeolite X while a further decrease in concentration of Cd (0.005 mg/L), Cr (BDL) and Pb (BDL) was observed for the sample treated with copper–zeolite composite. Zeolite X and copper-modified zeolite X showed complete elimination of total coliforms after 90 and 50 min contact time respectively. Conclusion: The results obtained in this study showed high antimicrobial disinfection and heavy metal removal efficiencies of the synthesized adsorbents. Furthermore, these sorbents are efficient in significantly reducing physical parameters such as electrical conductivity, turbidity, BOD and COD. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=WASTE%20WATER" title="WASTE WATER">WASTE WATER</a>, <a href="https://publications.waset.org/abstracts/search?q=COPPER%20DOPED%20ZEOITE%20X" title=" COPPER DOPED ZEOITE X"> COPPER DOPED ZEOITE X</a>, <a href="https://publications.waset.org/abstracts/search?q=ADSORPITION" title=" ADSORPITION"> ADSORPITION</a>, <a href="https://publications.waset.org/abstracts/search?q=HEAVY%20METAL" title=" HEAVY METAL"> HEAVY METAL</a>, <a href="https://publications.waset.org/abstracts/search?q=DISINFECTION" title=" DISINFECTION"> DISINFECTION</a>, <a href="https://publications.waset.org/abstracts/search?q=AKAKI%20RIVER" title=" AKAKI RIVER"> AKAKI RIVER</a> </p> <a href="https://publications.waset.org/abstracts/179364/design-and-synthesis-of-copper-zeolite-composite-for-antimicrobial-activity-and-heavy-metal-removal-from-waste-water" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/179364.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">72</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">11</span> The Lived Experience of Risk and Protective Contexts of Blind Successful University Students in Sidist Kilo Campus</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Zelalem%20Markos%20Borko">Zelalem Markos Borko</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The quality of life of people with blindness is significantly influenced by the level of resilience they possess. A qualitative approach of the descriptive phenomenological design was employed to address basic study objectives. The researcher purposely selected three blind graduate students from Sidist Kilo Campus and conducted a semi-structured interview to gather data. Data were analyzed by using thematic coding techniques. The present study found that personal characteristics such as commitment, living hope, motivation, positive self-esteem, self-confidence, and communication have shaped resiliency for successful university students with visual disabilities. The finding showed that the school environment is the place in which blind students had developed/experienced social, psychological, and economical competency and hope for their academic and entire life success. Furthermore, the finding showed that blind students had experienced individual, family, school, and community-related risks in the success track. Therefore, governmental and non-governmental organizations should provide training for students with visual impairments that focus on the individual traits that shape resilience for academic success, such as commitment, living hope, motivation, positive self-esteem, self-confidence, and communication and also community-oriented training should be to break the social stigma and discriminations for the individuals with the visual impairment. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=blind%20students" title="blind students">blind students</a>, <a href="https://publications.waset.org/abstracts/search?q=risk%20and%20protective%20factors" title=" risk and protective factors"> risk and protective factors</a>, <a href="https://publications.waset.org/abstracts/search?q=lived%20experience" title=" lived experience"> lived experience</a>, <a href="https://publications.waset.org/abstracts/search?q=success" title=" success"> success</a> </p> <a href="https://publications.waset.org/abstracts/168295/the-lived-experience-of-risk-and-protective-contexts-of-blind-successful-university-students-in-sidist-kilo-campus" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/168295.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">81</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">10</span> Assessment of Work-Related Stress and Its Predictors in Ethiopian Federal Bureau of Investigation in Addis Ababa</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Zelalem%20Markos%20Borko">Zelalem Markos Borko</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Work-related stress is a reaction that occurs when the work weight progress toward becoming excessive. Therefore, unless properly managed, stress leads to high employee turnover, decreased performance, illness and absenteeism. Yet, little has been addressed regarding work-related stress and its predictors in the study area. Therefore, the objective of this study was to assess stress prevalence and its predictors in the study area. To that effect, a cross-sectional study design was conducted on 281 employees from the Ethiopian Federal Bureau of Investigation by using stratified random sampling techniques. Survey questionnaire scales were employed to collect data. Data were analyzed by percentage, Pearson correlation coefficients, simple linear regression, multiple linear regressions, independent t-test and one-way ANOVA statistical techniques. In the present study13.9% of participants faced high stress, whereas 13.5% of participants faced low stress and the rest 72.6% of officers experienced moderate stress. There is no significant group difference among workers due to age, gender, marital status, educational level, years of service and police rank. This study concludes that factors such as role conflict, performance over-utilization, role ambiguity, and qualitative and quantitative role overload together predict 39.6% of work-related stress. This indicates that 60.4% of the variation in stress is explained by other factors, so other additional research should be done to identify additional factors predicting stress. To prevent occupational stress among police, the Ethiopian Federal Bureau of Investigation should develop strategies based on factors that will help to develop stress reduction management. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=work-related%20stress" title="work-related stress">work-related stress</a>, <a href="https://publications.waset.org/abstracts/search?q=Ethiopian%20federal%20bureau%20of%20investigation" title=" Ethiopian federal bureau of investigation"> Ethiopian federal bureau of investigation</a>, <a href="https://publications.waset.org/abstracts/search?q=predictors" title=" predictors"> predictors</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/168292/assessment-of-work-related-stress-and-its-predictors-in-ethiopian-federal-bureau-of-investigation-in-addis-ababa" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/168292.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">70</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">9</span> A Universal Troupe, “Athens Dramatic Company”: Tours and Performances (1887-1935)</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Papazafeiropoulou%20Olga">Papazafeiropoulou Olga</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The “Athens Dramatic Company” was one of the longest-running and most widely traveled troupes in the history of modern Greek theatre. The theatre company had been established since 1887, and the following: Euthychios Vonaseras, Eleni Kotopoulis, etc., like the founder of the troupe Theodoros Pofantis, referred to the distribution of the works presented in Patras: The price of a crime, The niece of her uncle, Agathopoulos, Amphitryon, The Two Sergeants, Lawyer and Actors, The Crusaders, The Daughter of Pantopolos, He Will Kill Himself, Macbeth, The Two Orphans, The Auction, Pistis Hope and Mercy, Love Attempt, The Crusaders, The lady is in Loutra, Markos Votsaris. In 1921, after peregrinations in Cyprus, Constantinople, Romania, Crete, Thessaloniki, Volos, Smyrna, the “Athens Dramatic Company” toured in Africa, where the Greek communities flourished. In 1923, the collaborations of troupe’s members and the repertoire varied several times, such as in Johannesburg, from where they traveled via Cape Town to Australia, where they presented the works: Dikaioma o Eros, Enochos, Psychokori, Kolokotronis. Atimoi, Voskopoula, Golfo, etc., while they impressed with the tragedy Oedipus Tyrannus, which was watched by Australians. Alongside the “Athens Dramatic Company” was also touring “Vrysoula’s Pantopoulos Troupe” and most of the members of the two troupes went to America, uniting their formation. In 1927, the old leader of “Athens Dramatic Company” (Theodoros Pofantis) decided to re-establish his troupe, but after unpleasant adventures, he passed away. In the year 1934, the Greek Dramatic Troupe of Athens revived with works including: The Man of the Day, A Dying Heart, A Dream Was and Gone, An Inspection, The Two Sergeants, The Mother, the Father-in-Law and the Non-existent Son-in-law, before finally expiring in 1935, after nearly 40 years of historical passage. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=athens" title="athens">athens</a>, <a href="https://publications.waset.org/abstracts/search?q=dramatic" title=" dramatic"> dramatic</a>, <a href="https://publications.waset.org/abstracts/search?q=company" title=" company"> company</a>, <a href="https://publications.waset.org/abstracts/search?q=universal" title=" universal"> universal</a>, <a href="https://publications.waset.org/abstracts/search?q=troupe" title=" troupe"> troupe</a> </p> <a href="https://publications.waset.org/abstracts/176757/a-universal-troupe-athens-dramatic-company-tours-and-performances-1887-1935" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/176757.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">72</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">8</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.

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 href="https://publications.waset.org/abstracts/search?q=Ethiopia" title=" Ethiopia"> Ethiopia</a>, <a href="https://publications.waset.org/abstracts/search?q=fixed-effect%20model" title=" fixed-effect model"> fixed-effect model</a>, <a href="https://publications.waset.org/abstracts/search?q=food%20security" title=" food security"> food security</a> </p> <a href="https://publications.waset.org/abstracts/163190/food-and-nutritional-security-in-the-context-of-climate-change-in-ethiopia-using-household-panel-data" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/163190.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">116</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">7</span> The Quasar 3C 47:Extreme Population B Jetted Source with Double-Peaked Profile</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Shimeles%20Terefe%20Mengistue">Shimeles Terefe Mengistue</a>, <a href="https://publications.waset.org/abstracts/search?q=Paola%20Marziani"> Paola Marziani</a>, <a href="https://publications.waset.org/abstracts/search?q=Ascensi%C3%B3ndel%20Olmo"> Ascensióndel Olmo</a>, <a href="https://publications.waset.org/abstracts/search?q=Jaime%20Perea"> Jaime Perea</a>, <a href="https://publications.waset.org/abstracts/search?q=Mirjana%20Povi%C4%87"> Mirjana Pović</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The theory that rotating accretion disks are responsible for the broad emission-line profiles in quasars is frequently put forth; however, the presence of accretion disk (AD) in active galactic nuclei (AGN) had limited and indirect observational support. In order to evaluate the extent to which the AD is a source of the broad Balmer lines and high ionization UV lines in radio-loud (RL) AGN, we focused on an extremely jetted RL quasar, 3C 47 that clearly shows a double peaked profile. This work presents its optical spectra and UV observations from the HST/FOS covering the rest-frame spectral range from 2000 to 7000 \AA. The fit of the low ionization lines, Hbeta, Halpha and MgII2800 show profiles that are in very good agreement with a relativistic Keplerian AD model. The profile of the prototypical high ionization lines can also be modeled by the contribution of the AD, with additional components due to outflows and emissions from the innermost part of the narrow line regions (NLRs). A prominent fit of the resulting double peaked profiles were found and very important disk parameters of the disk have been determined using the Hbeta, Halpha and MgII2800 lines: the inner and outer radii (both in units of G/mbh, where mbh is the supermassive black hole), an inclination to the line of sight, the emissivity index and the local broadening parameter. In addition, the accretion parameters, /mbh and /lledd are also determined. This work indicates that the line profile of 3C 47 shows the most convincing direct evidence for the presence of a rotating AD in AGN and the broad, double-peaked profiles originate from this AD that surrounds an /mbh. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=active%20galactic%20nuclei" title="active galactic nuclei">active galactic nuclei</a>, <a href="https://publications.waset.org/abstracts/search?q=quasars" title=" quasars"> quasars</a>, <a href="https://publications.waset.org/abstracts/search?q=emission%20lines" title=" emission lines"> emission lines</a>, <a href="https://publications.waset.org/abstracts/search?q=Double-peaked" title=" Double-peaked"> Double-peaked</a>, <a href="https://publications.waset.org/abstracts/search?q=supermassive%20black%20hole" title=" supermassive black hole"> supermassive black hole</a> </p> <a href="https://publications.waset.org/abstracts/175551/the-quasar-3c-47extreme-population-b-jetted-source-with-double-peaked-profile" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/175551.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">75</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">6</span> Prevalence of Visual Impairment among School Children in Ethiopia: A Systematic Review and Meta-Analysis</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Merkineh%20Markos%20Lorato">Merkineh Markos Lorato</a>, <a href="https://publications.waset.org/abstracts/search?q=Gedefaw%20Diress%20Alene"> Gedefaw Diress Alene</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Introduction: Visual impairment is any condition of the eye or visual system that results in loss/reduction of visual functioning. It significantly influences the academic routine and social activities of children, and the effect is severe for low-income countries like Ethiopia. So, this study aimed to determine the pooled prevalence of visual impairment among school children in Ethiopia. Methods: Databases such as Medical Literature Analysis and Retrieval System Online, Excerpta Medica dataBASE, World Wide Web of Science, and Cochrane Library searched to retrieve eligible articles. In addition, Google Scholar and a reference list of the retrieved eligible articles were addressed. Studies that reported the prevalence of visual impairment were included to estimate the pooled prevalence. Data were extracted using a standardized data extraction format prepared in Microsoft Excel and analysis was held using STATA 11 statistical software. I² was used to assess the heterogeneity. Because of considerable heterogeneity, a random effect meta-analysis model was used to estimate the pooled prevalence of visual impairment among school children in Ethiopia. Results: The result of 9 eligible studies showed that the pooled prevalence of visual impairment among school children in Ethiopia was 7.01% (95% CI: 5.46, 8.56%). In the subgroup analysis, the highest prevalence was reported in South Nations Nationalities and Tigray region together (7.99%; 3.63, 12.35), while the lowest prevalence was reported in Addis Ababa (5.73%; 3.93, 7.53). Conclusion: The prevalence of visual impairment among school children is significantly high in Ethiopia. If it is not detected and intervened early, it will cause a lifetime threat to visually impaired school children, so that school vision screening program plan and its implementation may cure the life quality of future generations in Ethiopia. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=visual%20impairment" title="visual impairment">visual impairment</a>, <a href="https://publications.waset.org/abstracts/search?q=school%20children" title=" school children"> school children</a>, <a href="https://publications.waset.org/abstracts/search?q=Ethiopia" title=" Ethiopia"> Ethiopia</a>, <a href="https://publications.waset.org/abstracts/search?q=prevalence" title=" prevalence"> prevalence</a> </p> <a href="https://publications.waset.org/abstracts/185116/prevalence-of-visual-impairment-among-school-children-in-ethiopia-a-systematic-review-and-meta-analysis" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/185116.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">37</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">5</span> Enhancing Green Infrastructure as a Climate Change Adaptation Strategy in Addis Ababa: Unlocking Institutional, Socio-Cultural and Cognitive Barriers for Application</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Eyasu%20Markos%20Woldesemayat">Eyasu Markos Woldesemayat</a>, <a href="https://publications.waset.org/abstracts/search?q=Paolo%20Vincenzo%20Genovese"> Paolo Vincenzo Genovese</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In recent years with an increase in the concentration of Green House Gases (GHG), Climate Change (CC) externalities are mounting, regardless of governments, are scrambling to implement mitigation and adaptation measures. With multiple social, economic and environmental benefits, Green Infrastructure (GI) has evolved as a highly valuable policy tool to promote sustainable development and smart growth by meeting multiple objectives towards quality of life. However, despite the wide range of benefits, it's uptake in African cities such as Addis Ababa is very low due to several constraining factors. This study, through content analysis and key informant interviews, examined barriers for the uptake of GI among spatial planners in Addis Ababa. Added to this, the study has revealed that the spatial planners had insufficient knowledge about GI planning principles such as multi-functionality, integration, and connectivity, and multiscale. The practice of implementing these holistic principles in urban spatial planning is phenomenally nonexistent. The findings also revealed 20 barriers categorized under four themes, i.e., institutional, socio-cultural, resource, and cognitive barriers. Similarly, it was identified that institutional barriers (0.756), socio-cultural barriers (0.730), cognitive barriers (0.700) and resource barriers (0.642), respectively, are the foremost impending factors for the promotion of GI in Addis Ababa. It was realized that resource barriers were the least constraining factor for enshrining the GI uptake in the city. Strategies to hasten the adoption of GI in the city mainly focus on improving political will, harmonization sectorial plans, improve spatial planning and implementation practice, prioritization of GI in all planning activities, enforcement of environmental laws, introducing collaborative GI governance, creating strong and stable institutions and raising awareness on the need to conserve environment and CC externalities through education and outreach mechanisms. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Addis%20Ababa" title="Addis Ababa">Addis Ababa</a>, <a href="https://publications.waset.org/abstracts/search?q=climate%20change" title=" climate change"> climate change</a>, <a href="https://publications.waset.org/abstracts/search?q=green%20infrastructure" title=" green infrastructure"> green infrastructure</a>, <a href="https://publications.waset.org/abstracts/search?q=spatial%20planning" title=" spatial planning"> spatial planning</a>, <a href="https://publications.waset.org/abstracts/search?q=spatial%20planners" title=" spatial planners"> spatial planners</a> </p> <a href="https://publications.waset.org/abstracts/121570/enhancing-green-infrastructure-as-a-climate-change-adaptation-strategy-in-addis-ababa-unlocking-institutional-socio-cultural-and-cognitive-barriers-for-application" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/121570.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">121</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">4</span> Design and Synthesis of Copper Doped Zeolite Composite for Antimicrobial Activity and Heavy Metal Removal from Waste Water</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Feleke%20Terefe%20Fanta">Feleke Terefe Fanta</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The existence of heavy metals and microbial contaminants in aquatic system of Akaki river basin, a sub city of Addis Ababa, has become a public concern as human population increases and land development continues. This is because effluents from chemical and pharmaceutical industries are directly discharged onto surrounding land, irrigation fields and surface water bodies. In the present study, we synthesised zeolites and copper- zeolite composite based adsorbent through cost effective and simple approach to mitigate the problem. The study presents determination of heavy metal content and microbial contamination level of waste water sample collected from Akaki river using zeolites and copper- doped zeolites as adsorbents. The synthesis of copper- zeolite X composite was carried out by ion exchange method of copper ions into zeolites frameworks. The optimum amount of copper ions loaded into the zeolites frameworks were studied using the pore size determination concept via iodine test. The copper- loaded zeolites were characterized by X-ray diffraction (XRD). The XRD analysis showed clear difference in phase purity of zeolite before and after copper ion exchange. The concentration of Cd, Cr, and Pb were determined in waste water sample using atomic absorption spectrophotometry. The mean concentrations of Cd, Cr, and Pb in untreated sample were 0.795, 0.654 and 0.7025 mg/L respectively. The concentration of Cd, Cr, and Pb decreased to 0.005, 0.052 and BDL mg/L for sample treated with bare zeolite X while a further decrease in concentration of Cd, Cr, and Pb (0.005, BDL and BDL) mg/L respectively was observed for the sample treated with copper- zeolite composite. The antimicrobial activity was investigated by exposing the total coliform to the Zeolite X and Copper-modified Zeolite X. Zeolite X and Copper-modified Zeolite X showed complete elimination of microbilas after 90 and 50 minutes contact time respectively. This demonstrates effectiveness of copper- zeolite composite as efficient disinfectant. To understand the mode of heavy metals removal and antimicrobial activity of the copper-loaded zeolites; the adsorbent dose, contact time, temperature was studied. Overall, the results obtained in this study showed high antimicrobial disinfection and heavy metal removal efficiencies of the synthesized adsorbent. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=waste%20water" title="waste water">waste water</a>, <a href="https://publications.waset.org/abstracts/search?q=copper%20doped%20zeolite%20x" title=" copper doped zeolite x"> copper doped zeolite x</a>, <a href="https://publications.waset.org/abstracts/search?q=adsorption%20heavy%20metal" title=" adsorption heavy metal"> adsorption heavy metal</a>, <a href="https://publications.waset.org/abstracts/search?q=disinfection" title=" disinfection"> disinfection</a> </p> <a href="https://publications.waset.org/abstracts/168687/design-and-synthesis-of-copper-doped-zeolite-composite-for-antimicrobial-activity-and-heavy-metal-removal-from-waste-water" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/168687.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">82</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">3</span> Machine Learning Model to Predict TB Bacteria-Resistant Drugs from TB Isolates</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Rosa%20Tsegaye%20Aga">Rosa Tsegaye Aga</a>, <a href="https://publications.waset.org/abstracts/search?q=Xuan%20Jiang"> Xuan Jiang</a>, <a href="https://publications.waset.org/abstracts/search?q=Pavel%20Vazquez%20Faci"> Pavel Vazquez Faci</a>, <a href="https://publications.waset.org/abstracts/search?q=Siqing%20Liu"> Siqing Liu</a>, <a href="https://publications.waset.org/abstracts/search?q=Simon%20Rayner"> Simon Rayner</a>, <a href="https://publications.waset.org/abstracts/search?q=Endalkachew%20Alemu"> Endalkachew Alemu</a>, <a href="https://publications.waset.org/abstracts/search?q=Markos%0D%0AAbebe"> Markos Abebe</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Tuberculosis (TB) is a major cause of disease globally. In most cases, TB is treatable and curable, but only with the proper treatment. There is a time when drug-resistant TB occurs when bacteria become resistant to the drugs that are used to treat TB. Current strategies to identify drug-resistant TB bacteria are laboratory-based, and it takes a longer time to identify the drug-resistant bacteria and treat the patient accordingly. But machine learning (ML) and data science approaches can offer new approaches to the problem. In this study, we propose to develop an ML-based model to predict the antibiotic resistance phenotypes of TB isolates in minutes and give the right treatment to the patient immediately. The study has been using the whole genome sequence (WGS) of TB isolates as training data that have been extracted from the NCBI repository and contain different countries’ samples to build the ML models. The reason that different countries’ samples have been included is to generalize the large group of TB isolates from different regions in the world. This supports the model to train different behaviors of the TB bacteria and makes the model robust. The model training has been considering three pieces of information that have been extracted from the WGS data to train the model. These are all variants that have been found within the candidate genes (F1), predetermined resistance-associated variants (F2), and only resistance-associated gene information for the particular drug. Two major datasets have been constructed using these three information. F1 and F2 information have been considered as two independent datasets, and the third information is used as a class to label the two datasets. Five machine learning algorithms have been considered to train the model. These are Support Vector Machine (SVM), Random forest (RF), Logistic regression (LR), Gradient Boosting, and Ada boost algorithms. The models have been trained on the datasets F1, F2, and F1F2 that is the F1 and the F2 dataset merged. Additionally, an ensemble approach has been used to train the model. The ensemble approach has been considered to run F1 and F2 datasets on gradient boosting algorithm and use the output as one dataset that is called F1F2 ensemble dataset and train a model using this dataset on the five algorithms. As the experiment shows, the ensemble approach model that has been trained on the Gradient Boosting algorithm outperformed the rest of the models. In conclusion, this study suggests the ensemble approach, that is, the RF + Gradient boosting model, to predict the antibiotic resistance phenotypes of TB isolates by outperforming the rest of the models. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=machine%20learning" title="machine learning">machine learning</a>, <a href="https://publications.waset.org/abstracts/search?q=MTB" title=" MTB"> MTB</a>, <a href="https://publications.waset.org/abstracts/search?q=WGS" title=" WGS"> WGS</a>, <a href="https://publications.waset.org/abstracts/search?q=drug%20resistant%20TB" title=" drug resistant TB"> drug resistant TB</a> </p> <a href="https://publications.waset.org/abstracts/181519/machine-learning-model-to-predict-tb-bacteria-resistant-drugs-from-tb-isolates" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/181519.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">52</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">2</span> Multilevel of Factors Affected Optimal Adherence to Antiretroviral Therapy and Viral Suppression amongst HIV-Infected Prisoners in South Ethiopia: A Prospective Cohort Study</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Terefe%20Fuge">Terefe Fuge</a>, <a href="https://publications.waset.org/abstracts/search?q=George%20%20Tsourtos"> George Tsourtos </a>, <a href="https://publications.waset.org/abstracts/search?q=Emma%20Miller"> Emma Miller</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Objectives: Maintaining optimal adherence and viral suppression in people living with HIV (PLWHA) is essential to ensure both preventative and therapeutic benefits of antiretroviral therapy (ART). Prisoners bear a particularly high burden of HIV infection and are highly likely to transmit to others during and after incarceration. However, the level of adherence and viral suppression, as well as its associated factors in incarcerated populations in low-income countries is unknown. This study aimed to determine the prevalence of non-adherence and viral failure, and contributing factors to this amongst prisoners in South Ethiopia. Methods: A prospective cohort study was conducted between June 1, 2019 and July 31, 2020 to compare the level of adherence and viral suppression between incarcerated and non-incarcerated PLWHA. The study involved 74 inmates living with HIV (ILWHA) and 296 non-incarcerated PLWHA. Background information including sociodemographic, socioeconomic, psychosocial, behavioural, and incarceration-related characteristics was collected using a structured questionnaire. Adherence was determined based on participants’ self-report and pharmacy refill records, and plasma viral load measurements which were undertaken within the study period were prospectively extracted to determine viral suppression. Various univariate and multivariate regression models were used to analyse data. Results: Self-reported dose adherence was approximately similar between ILWHA and non-incarcerated PLWHA (81% and 83% respectively), but ILWHA had a significantly higher medication possession ratio (MPR) (89% vs 75%). The prevalence of viral failure (VF) was slightly higher (6%) in ILWHA compared to non-incarcerated PLWHA (4.4%). The overall dose non-adherence (NA) was significantly associated with missing ART appointments, level of satisfaction with ART services, patient’s ability to comply with a specified medication schedule and types of methods used to monitor the schedule. In ILWHA specifically, accessing ART services from a hospital compared to a health centre, an inability to always attend clinic appointments, experience of depression and a lack of social support predicted NA. VF was significantly higher in males, people of age 31-35 years and in those who experienced social stigma, regardless of their incarceration status. Conclusions: This study revealed that HIV-infected prisoners in South Ethiopia were more likely to be non-adherent to doses and so to develop viral failure compared to their non-incarcerated counterparts. A multitude of factors was found to be responsible for this requiring multilevel intervention strategies focusing on the specific needs of prisoners. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Adherence" title="Adherence ">Adherence </a>, <a href="https://publications.waset.org/abstracts/search?q=Antiretroviral%20therapy" title=" Antiretroviral therapy"> Antiretroviral therapy</a>, <a href="https://publications.waset.org/abstracts/search?q=Incarceration" title=" Incarceration"> Incarceration</a>, <a href="https://publications.waset.org/abstracts/search?q=South%20Ethiopia" title=" South Ethiopia"> South Ethiopia</a>, <a href="https://publications.waset.org/abstracts/search?q=Viral%20suppression" title=" Viral suppression"> Viral suppression</a> </p> <a href="https://publications.waset.org/abstracts/138366/multilevel-of-factors-affected-optimal-adherence-to-antiretroviral-therapy-and-viral-suppression-amongst-hiv-infected-prisoners-in-south-ethiopia-a-prospective-cohort-study" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/138366.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">135</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">1</span> Optical and Near-UV Spectroscopic Properties of Low-Redshift Jetted Quasars in the Main Sequence in the Main Sequence Context</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Shimeles%20Terefe%20Mengistue">Shimeles Terefe Mengistue</a>, <a href="https://publications.waset.org/abstracts/search?q=Ascensi%C3%B3n%20Del%20Olmo"> Ascensión Del Olmo</a>, <a href="https://publications.waset.org/abstracts/search?q=Paola%20Marziani"> Paola Marziani</a>, <a href="https://publications.waset.org/abstracts/search?q=Mirjana%20Povi%C4%87"> Mirjana Pović</a>, <a href="https://publications.waset.org/abstracts/search?q=Mari%CC%81a%20Angeles%20Marti%CC%81nez-Carballo"> María Angeles Martínez-Carballo</a>, <a href="https://publications.waset.org/abstracts/search?q=Jaime%20Perea"> Jaime Perea</a>, <a href="https://publications.waset.org/abstracts/search?q=Isabel%20M.%20%C3%81rquez"> Isabel M.

The absence of spectra with a high S/N ratio led to the impression that all quasars (QSOs) are spectroscopically similar. Although different attempts were made to unify these two classes, there is a long-standing open debate involving the possibility of a real physical dichotomy between RL and RQ quasars. In this work, we present new high S/N spectra of 11 extremely powerful jetted quasars with radio-to-optical flux density ratio > 1000 that concomitantly cover the low-ionization emission of Mgii𝜆2800 and Hbeta𝛽 as well as the Feii blends in the redshift range 0.35 < z < 1, observed at Calar Alto Observatory (Spain). This work aims to quantify broad emission line differences between RL and RQ quasars by using the four-dimensional eigenvector 1 (4DE1) parameter space and its main sequence (MS) and to check the effect of powerful radio ejection on the low ionization broad emission lines. Emission lines are analysed by making two complementary approaches, a multicomponent non-linear fitting to account for the individual components of the broad emission lines and by analysing the full profile of the lines through parameters such as total widths, centroid velocities at different fractional intensities, asymmetry, and kurtosis indices. It is found that broad emission lines show large reward asymmetry both in Hbeta𝛽 and Mgii2800A. The location of our RL sources in a UV plane looks similar to the optical one, with weak Feii UV emission and broad Mgii2800A. We supplement the 11 sources with large samples from previous work to gain some general inferences. The result shows, compared to RQ, our extreme RL quasars show larger median Hbeta full width at half maximum (FWHM), weaker Feii emission, larger 𝑀BH, lower 𝐿bol/𝐿Edd, and a restricted space occupation in the optical and UV MS planes. The differences are more elusive when the comparison is carried out by restricting the RQ population to the region of the MS occupied by RL quasars, albeit an unbiased comparison matching 𝑀BH and 𝐿bol/𝐿Edd suggests that the most powerful RL quasars show the highest redward asymmetries in Hbeta. <p class="card-text"><strong>Keywords:</strong> <a
