    Assessment of Vocational Behavior of Persons with . Mental Retardation in Addis Ababa
    (Addis Ababa University, 2006-06) Bogale, Kassahun; Desta, Daniel (PhD)
    The participants of this study were thirty two students (mild males=9, mild females =3 ,moderate males=J2 and moderatefemales=8), six teachers, two principals of the center, and one Ministry of Labor and Social Affair team leader of persons with disabilities. Except the students all of them were selected using pwposive sampling method; hence the students were selected by random sampling. Four data collection instruments were used, namely, competency rating scale, questionnaire, interview, and document analysis. In order to analyze the data both qualitative and quantitative analysis were used The result showed that in center of mental retardation there are ten varieties of prevocational adaptive skills and prevocational skills training given for students with mental retardation. The majority of the students were competent in these skills training, except in functional academics and petty trading; and their first vocational skill training choice was janitorial activity. Moreover, the performance on prevocational adaptive skill was correlated with prevocational skill training. On the other hand, the pelformance on these skills training analyzed by sex seems to appear in favor of males, where as in the case level of retardation, mild students performed bener than those of moderate with some exceptions. The results also showed that persons with mental retardation have higher rates of unemployment comparing with persons with and with out disabilities. In addition, the finding indicated that the main challenge of the implementation policy was financial shortage, lack of skilled persons, and lack of awareness. This study concluded that students with mental retardation are able to perform different tasks of vocational skills training options with appropriate order and supervision. Despite this demonstration of competency, many persons with mental retardation are underemployed However, few of them have job in non-governmental organizations Suggestions and recommendations based on this study are included

    Early Numerical Intervention Utilizing Ethiopian Gabat’a on Achievement and Motivation of Students with Mathematics Difficulties
    (AAU, 2021-06) Bogale, Kassahun; T/Mariam, Alemayehu(DR
    In the field of mathematics difficulties, there is an often-noted lack of researches. The present study investigated the effect of concrete fading numerical intervention utilizing gabat‘a on early numerical achievement and early mathematics motivation of primary school students with MD. Gabat‘a, the Ethiopian indigenous math game, has six holes, two storages, and stones/beads for playing in pair.In the present study, it was organized for dual purposes: for instruction and game. Children with MD exhibit multifaceted problems in comparison with their counter parts. These lead them to have long term educational problems. At 3 sites, 72 students with MD were screened using BANUCA and other screening tools. A method of quantitative experimental research utilizing pretest-posttest control group design was used in tandem with MANCOVA to analyze the data. The design used stratified randomization, taking gender, difficulty type, prior mathematics knowledge as a strata and then randomly allocated into: Experiment 1 entailed two groups, CIGO and control group; and experiment 2 involved three groups, AIGG, AIGO, and control group. The interventions occurred in total for 18 week, 3 sessions per week and 45–60 min per session. Then, a MANCOVA result shows that students with MD in both experiments exhibited significantly higher performance than control group on counting and number concept achievement, arithmetic achievement, and early mathematics motivation. However, students with MD in AIGG condition did not show significant performances than that of AIGO condition. In addition, the findings indicated that mostly gender, difficulty type, and prior mathematics knowledge did not play significant roles in achievement and early mathematics motivation. With respect to correlational results, within the addition and subtraction constructs, the correlation was highest, similar results were found in cross correlation as well. The multiple regression findings indicated that addition had a unique significant contribution for subtraction than counting. Moreover, a canonical correlation shows that early mathematics motivation positively influenced achievement of counting and number concept, but not for arithmetic. To recap, the CRA sequence utilizing gabat‘a is effective in teaching early numeral interventions for students who struggle in mathematics. This pattern of instructional intervention could be, robust techniques of counting and number concept and arithmetic teaching in the future, which integrated with classroom activities if teachers want to increase students‘ early numerical performance and early mathematics motivation. Practical implications, limitation of the study, and suggestions for future research in this area are provided.

    Outcome of patients with Acute Coronary Syndrome admitted to Tikur Anbessa Specialized Hospital, Addis Ababa, Ethiopia
    (Addis Ababa University, 2017-01) Bogale, Kassahun; Nedi, Teshome (PhD)
    Outcome of patients with Acute Coronary Syndrome admitted to Tikur Anbessa Specialized Hospital, Addis Ababa, Ethiopia Kassahun Bogale Addis Ababa University, 2017 Worldwide, coronary artery disease (CAD) is the single most frequent cause of death. Over seven million people every year die from CAD, accounting for 12.8% of all deaths. The objective of this study was to assess the treatment outcome and associated factors for Acute Coronary Syndrome (ACS) patients admitted at Tikur Anbessa Specialized Hospital (TASH). A retrospective cross sectional study was conducted by chart review of patients who were discharged with a diagnosis of ACS during the period January 1, 2012 to December 31, 2014. Of 124 ACS patients who were admitted during the three years period, 90(72.6%) were diagnosed as STEMI. The mean age was 56.3 ±13.7 years. The average length of hospital stay was 9.77± 6.42 days. The average time from onset of ACS symptoms to presentation in the emergency department was 3.8 days (91.7 hours). In about 76 (61.3%) patients hypertension was the leading risk factor for development of ACS. 36.4% of ACS patients in TASH were either Killip class III or IV. Biomarkers were measured for 118(95.2%) patients. 79.2% of patients had ejection fraction (EF) of less than 40% and 29.2% had less than 30%. In-hospital medications include loading dose of aspirin (79%), anti-coagulants (77.4%), beta-blockers (88.1%), statins (85.5%), morphine (12.9%), and nitrates (35.5%). The in-hospital mortality was 27.4%. Predictors of inhospital mortality in TASH included age (P=0.042), time from symptom onset to presentation (P=0.001), previous history of hypertension (P=0.025), being Killip class III and IV (P=0.001), and STEMI diagnosis (P=0.005). Hence, based on the results the medical management of ACS patients in TASH was in line with the recommendations of international guidelines but inhospital mortality was very high (27.4%).
