    Assessement of Health Care Providers‘ Attitude and Associated Factors Towards Safe Abortion Care at Public Health Institiutions in East Gojjam Zone, Amhara, Ethiopia, Cross Sectional Study,2015
    (Addis Ababa University, 2015-06) Abebe, Meskerem; Berhe, Semarya (PhD)
    Background: Globally, unsafe abortion has become one of the fifith causes of maternal mortality and morbidity. Studies suggested that health care providers‘ attitudes towards safe abortion had an impact on safe abortion. In the countries where abortion is one of the major challenges, such attitudinal assessment is vital. The reason is that in Ethiopia, the annual rate of abortion was 23 per 1, 000 women aged 15-44 and the abortion ratio was 13 per 100 live birth. It was supposed that maternal mortality is closely related to the quality of health facilities and professionals. Objective: Assessment of Health Care Providers‘ Attitude and Associated Factors towards Safe Abortion care at Public health institution, in East Gojjam zone Amhara, Ethiopia, Cross Sectional Study, 2015. Method: A descriptive cross sectional study was done from January to June, 2015 using self administrative questionnaire. 249 samples of health care providers were targeted. Of these, 238 respondents completed and returned the questionnaires completel y. Hence, with the response rate of 96.5%, the data was coded into Epi data version 3.1 and computed with SPSS version 21 for its statistical significance and cross tabulation. The data was interpreted with simple frequency distribution,cross tabulation, logistic regression for statistical significance with confidence interval of 95 % of alpha 0.05. Result : The study revealed that 92.4% of health care providers believed that unsafe abortion was one of the major health problems in Ethiopia. Providers who had formal training were 3.740[95% CI 1.728-8.094] times more likely to have favorable attitudes than those who had no training. Similarl y, providers who had perform abortion were 2.025[95% CI 1.050-3.905] times more likely to have favorable attitudes than those who did not perform. Those health care providers who needed more legalization were 2.243[95% CI 1.059- 4.752] times more likely to have favorable attitudes than those who did not support more legalization Conclusion and Recommendation: It was concluded that training and more legalization were found to be significant to determine the attitudes of health care providers. It is recommended that health care providers should be given abortion training and legaliz ation to abortion should be more liberalized than the current status. Key words: Health care provider, attitude, and safe abortion care

    Knowledge Based System for Fault Iso lation and Diagnosis of Aircraft Maintenance in Ethiopian Airlines
    (Addis Ababa University, 2009-10) Abebe, Meskerem; Meshesha, Million (PhD); Gudeta, Haileleoul (PhD)
    Fault isolation and diagnosis is one of the key aircraft maintenance activities performed in Ethiopian Airlines. The main features of fault diagnosis in aircraft maintenance involve multidisciplinary knowledge in aircraft functional systems and the indefinite relationship between .symptom and source or failure. In order 10 facilitate these activities the experience and knowledge of aircraft technicians plays a significant role in quickly solving aircraft system failures without delaying flight schedules. However the airline is losing significant amount of skilled and experienced technicians whose contribution to the fault diagnosis was invaluable. A knowledge based system is developed to .facilitate the fault isolation technique., in aircrafi maintenance using the experience and knowledge of skilled technicians along with the relevant mail1lenance documents and maintenance records. The domain knowledge modeling is performed using decision trees in such a way that a rule based inference can be implemented for knowledge representation. The prototype developed employs the utilization of,/ac(s and come up with conclusions based on the backward chaining inference. The rules in (he knowledge base are constructed Form analyzing the records of the aircraft maintenance resume book along with (he available maintenance documel1ls. A prolog programming language is used to demonstrate the prototype and (he result of the study has revealed that there is an accuracy of 86%. Adopting the knowledge based system is supposed to retain the aircraft maintenance knowledge and makes the airline stronger by itself rather than depending fully on human experts. The knowledge based .system needs further works in updating its knowledge base when new facts are introduced besides of creating generalized pattern for identifying system faults.
