    Local Community Participation in Alternative Basic Education Program in North Wollo Challenges and Prospects
    (Addis Ababa University, 2007-03) Tadesse, Samuel; Ingdayehu, yalew (PhD)
    Basic education is a key element to development. Recognizing this, worldwide effort has been made to access basic education for all in a shortest time possible. Hence, alternative approaches such as alternative basic education program (ABEP) came into being. One of the purposes of introducing this alternative approach to basic education is to make a difference in regard to local community participation. It is to create a sense of ownership and to initiate the whole community to participate actively. However, in spite of physical proximity, fiexibilities, facilities and other peculiarities of the program, the local communities ' involvement in the ABEP seems unsatisfactory, limited and almost all problems that are related to local community participation in the formal program are still persisting. This motivates the researcher to assess the challenges and prospects of the local community participation in the ABEP in the study area (North Wollo). To this end, a descriptive survey method was used as an appropriate methodology to reflect the intended purpose of the study. Besides, the Input - Process - Output (IPO) model was used to identify the available inputs, the nature of the process and the results to identify the challenges and prospects of the local community participation. Relevant data on a wide range of issues pertinent to the study were collected from three woredas of North Wollo namely Kobo, Meket and Wadla. The basic instruments used were questionnaire, focus group discussions and structured interviews. The respondents were education experts, school cluster supervisors, ABE facilitators, ABE centre management committees, ABE students, parents and other local community members. Looking through the process, forms and extents of participation of the local communities, the study identified challenges of local community participation in ABEP and prospects for active participation. The major challenges identified are mismatch of interest and economic capacity of local communities to participate, low level of awareness of local communities on ABEP, lack of adequate and relevant procedures / guidelines, high expectation of external support (donation and other external support), lack of joint planning mechanisms among sectors of the woredas, absence of formal mechanisms to maintain and transform knowledgelinformation and documents. Consequently, the prospect seems blurred and active participation might not be obtained, unless those obstacles are removed timely. Finally, the study includes recommendations. The major recommendations are: prepare user friendly and relevant procedures / guidelines specifically on ABEP and community participation, design formal mechanism to transfer knowledge/ information and documents, provide detail orientation to the local community; and create mechanism to enable government sectors to plan their schedule jointly.

    Prospective Cross sectional study of Radio-Pathologic correlation of soft tissue tumors in patients evaluated at Tikur Anbessa specialized hospital and St Paul millennium medical college, Addis Ababa University, Addis Ababa, Ethiopia, 2019
    (Addis Abeba University, 2019-08) Tadesse, Samuel; Admassie, Daniel (MD, professor of Radiology); Zenebe, Moges(MD, Assistant professor of Radiology); Gezahegn, Hiwot (MD, Assistant professor of Radiology)
    Introduction: Soft tissue is the supportive tissue of various organs and the non-epithelial, extra skeletal structures exclusive of lympho-hematopoietic tissues. It includes fibrous connective tissue, adipose tissue, skeletal muscle, blood/lymph vessels, and the peripheral nervous system. Most soft tissue tumors are classified as ether benign and malignant there are also intermediate groups implying aggressive local behavior with low to moderate probability for metastasis. Soft tissue tumors are classified histologically on the basis of the adult tissue they resemble. Objective: Assessment of radio-pathologic correlation of soft tissue tumors in patients evaluated at Tikur Anbessa Specialized Hospital, Addis Ababa, Ethiopia 2019. Method: The study was conducted at TASH from May 2018-January 2019. Hospital based prospective cross sectional study was conducted at TASH to address the specific objective during study period. The Study was conducted among patients being evaluated at Tikur Anbessa Specialized Hospital oncology department who have both MRI and pathology result during study period. Data was collected by evaluating the MRI report and biopsy result from oncology department and also using structured questionnaires. The data was checked for clarity and completeness. Computerized data analysis was conducted by using SPSS version 25 software. Result: Total of 73 cases evaluated with 60% malignant. The sensitive MRI parameters for malignancy are size >5cm (91%), necrosis (82%), bone involvement (80%). The specific MRI parameters include age>25yr (86%), necrosis (78%), heterogeneous enhancement (75%). From all the MRI parameters only necrosis had significant correlation with malignancy on imaging in our study. Conclusion: The most sensitive and specific MRI parameter to predict malignancy in our study are size > 5cm, necrosis, heterogeneous enhancement. Necrosis had significant correlation for malignancy.
