    Breaking Bad News Knowledge and Attitude of Junior Physician Practicing at Tikur Anbessa Specialized Hospital, Addis Ababa, Ethiopia.
    (Addis Abeba University, 2021-12) Mitiku, Tilahun; Dr.Merkebu, Ermias(Pulmonologist and Critical care specialist)
    Introduction: Breaking bad news to patients or discussing a serious case with a patient is part of the daily activity of many healthcare professionals and it is an inevitable clinical duty. In a Medical setting bad news is any information likely to alter drastically a patient's view of his or her future perspectives and vision of life. Effective communication skills of delivering bad news are very important to develop good patient-physician relationships. Objective; To assess the Knowledge, and Attitude of TASH Junior physicians about breaking bad news. Methods: An institutional-based cross-sectional study at Tikur Anbessa specialized hospital, Addis Ababa Ethiopia from August to October 2021, and comprised 286 postgraduate residents of different specialties making a 98% response rate. Their knowledge and attitude were assessed by using a specifically-designed questionnaire based on SPIKES protocol. It is a six-step protocol of Setting, Perception, Invitation, Knowledge, Empathy, and Summarizing model. Data were collected through self-administered questionnaires and online surveys. The collected data were entered into Microsoft excel, then it was exported to SPSS of version 26.0 for analysis. Bivariate and multivariate analysis using logistic regression models was used to determine the association between different predictor variables with the dependent variable Results: Among 286 respondents, 201 (70.3%) were males and 85(29.7) were females and the mean age of the participants was 29.69 years (SD±2.205) years).98.3% of participants have been involved in breaking bad news, (37.1%) admitted bad experience in breaking bad news and 87.6% did not have any specific teaching or training on BBN. The mean and median score of the participants' knowledge about breaking bad news in this study was 5.94 (SD ± 1.100) and 6 respectively. Among participants, 70.3% had good knowledge, followed by a poor knowledge (16.4%) and a Moderate level of knowledge (13.3%). From self-reported breaking bad news skills majority of participants (57.7%) of participants were only fairly satisfied with their BBN skills. Conclusion Most of the participating physicians didn’t receive any training on BBN, a substantial number of residents didn't follow BBN protocol. Even though a majority of participants had good knowledge they had little satisfaction regarding their BBN skills Recommendation Education and training for trainees during their residency programs to improve their BBN skills should be considered and adoption of BBN protocol

    Determinants of Credit Risk Management Effectiveness in Private Commercial Banks in Ethiopia
    (A.A.U, 2022-03) Mitiku, Tilahun; Teklu, Tilahun (PhD)
    Risk management involves a set of tool and models for measuring and controlling risk. There is a research gap in risk understanding, risk identification system, risk assessment and analysis, risk monitoring system, and risk evaluation determinants in the Ethiopian context in general and in the study area in particular. The main objective of this study is to examine determinants of credit risk management effectiveness in Ethiopian private commercial banks in Addis Ababa city. A quantitative research and explanatory research method is used. The data was collected using self-administered close ended structured questionnaires from 166 respondents by using nonrandom sample technique called convenience sampling technique. Descriptive statistics and multiple linear regressions were used for analysis. Assumptions are tested to check the appropriateness of multiple linear regressions for analysis. The descriptive statistics result of (risk understanding, risk assessment and analysis, risk monitoring system, and risk evaluation) mean score is high which is above the mean score of point 3 and risk identification system has medium value. The multiple regression analysis result revealed that the four predictors risk understanding, risk identification system, risk assessment and analysis, and risk evaluation have significant and positive coefficient of beta values indicating that they have positive effect on credit risk management effectiveness under the study while one predictor risk monitoring system has insignificant alpha valve which indicated that it has no any effect on credit risk management effectiveness under the study. It is recommended that the managers of each bank had better to maintain current established risk management techniques and that employees are expected to perceive in the bank; the management of each bank also set up proper risk identification mechanism to minimize occurrence of high risk in the bank; they had better asses and analysis their effectiveness related to loan and repayment performance in the bank ; each private commercial bank in Ethiopia had better continue the timely evaluation of financial risks to find out measurements to be taken in order to maintain safe balance of loan in the bank. Key Words: Credit risk management effectiveness, Risk understanding, risk identification system, risk assessment and analysis, risk monitoring system, and risk evaluation

    Study on Technical Feasibility and Design of Grid Connected Solar PV Based Power Supply System for the Ethio-Djibouti Railway Line
    (Addis Ababa University, 2020-10) Mitiku, Tilahun; Fekadu, Shewarga (PhD)
    In this thesis work the technical feasibility, design, and simulation of a single-phase grid-connected PV system is studied. The aim is to design and simulate a single-phase grid-connected PV system for railway traction applications. The design of a single-phase grid-connected PV system now days is applicable for residential, commercial, and also for large scale PV farms. To design and simulate the system, solar radiation of the site should be estimated well. Solar radiation of the site Adama, Metehara, Awash Arba, and Asebe Teferi is estimated by using temperature method and the average obtained results are 6.62 kWh/m2, 7.26 kWh/m2, 6.891 kWh/m2 and 6.45 kWh/m2 respectively. The accuracy of the estimated solar radiation values was tested by computing the MBE, RMSE, and MPE. The value of MBE and RMSE should be small as seen from the obtained results the estimated shows that the obtained value is minimum. The estimated MPE value should be in the range of (±10%) to testify the estimated value is accurate or not then, the result shows that MPE value is between in the range. The designed system to harass energy from the PV system shows that the designed power is enough to run the trainload. And also it saves 124,980.44 tons of Co2 emissions during the lifetime of the project. The designed thesis will be applicable for railway traction of Ethio-Djibouti railway routes specifically around Awash Arba sections. Design will be designed and simulated by using well know software Matlab/Simulink. The design consideration for this thesis is 1 MW to run the trainload based on the technical proposal of ERC the train load is 815.4 kW. Boosting converter is used to step-up DC voltage due to the drawback of PV system efficiency. The simple and very popular perturbed and observe MPPT method is used in this thesis works to increase solar system efficiency. This MPPT produces a duty cycle that is dependent on PV module voltage and power. The output voltage of the boost converter ranges from 1500-1600 V. The feasibility of the designed system is studied and it takes 4.61 years of payback and which is feasible. Based on the technical proposal of Ethiopian Railway Corporation daily and annual energy consumption of the trainload is calculated and the result obtained is 3686.05 kWh and 1345.4 MWh respectively. For this thesis research energy generated from the single-phase grid-connected PV system is estimated monthly and annually and the obtained result is 884564.85 kWh and 10415.036 MWh respectively.
