    (Addis Ababa University, 2014-06) Abraham Yohannes; Hussein Kedir
    This study was conducted to explore practices and problems of secondary School Leaderships in West Wollega Administrative Zone. To this effect, a descriptive survey method was employed. Questionnaire, interview, FGD and document analysis were used as data gathering tools. The data were collected from 5 secondary schools which are found in 5 woredas of the administrative zone. The schools and woredas were selected by simple random sampling technique. Based on this, a total of 112 teachers were selected by simple random sampling technique. 15 principals, 5 secondary school supervisors, 5 WEOs and 5 PTA leaders were selected by purposive sampling technique and included as a subject of the study. The data were tabulated and analyzed with the help of percentage, mean, frequency, and t-test. The finding of the study revealed that majority of the principals were not qualified in the position they hold currently and they were assigned to the position by merits only without keeping the directives of MoE. School leadership were found to be in good position in practices like inspiring the school vision, preparing appropriate school plan, participating the staff in decision making process and in developing mechanisms of sharing experiences. But the school leadership has limitations in practices like supervision and curriculum development practices. Moreover qualification and experience, organizing and situation related problems were the challenges that secondary school leadership faced. Based on the findings one can conclude that for assigning appropriate person the concerned body did not keep the directives set by MoE, school principals were not included themselves in supervising and visiting the classroom, The interest of a community to participate in school affairs was low (has no continuity), the school leadership were not integrate, coordinate and organize all managerial roles to implement at school level. More over problems related qualification, organizing and situational problems were the problems of school leadership. Based on conclusion to assign appropriate person to the position keeping the directives set by MoE, principals included the selves in supervising and visiting class room, to extend the interest of the community to participate in school affairs all concerned body arrange awareness raising conferences, to avoid problems related to qualification arranging short and long term training were adivised and for organizing problem collaboration work with staff members were recommended to bring about the effectiveness of their tasks

    Sensitivity and Specificity of Fine Needle Aspiration Cytology on Breast Mass as Compared to Histology Evaluation
    (Addis Ababa University, 2014-10) Abraham Yohannes
    Introduction: Breast cytology has been used for many years as a diagnostic tool for managing patients with breast lesions. In experienced hands, FNAB was found to be highly sensitive and specific. Objective: To evaluate the accuracy and diagnostic performance of fine needle aspiration FNA cytology in diagnoses of breast masses. Methods: FNA diagnoses and biopsy of breast masses of patients who underwent subsequent histopathologic evaluation during June2013-June2014 at Black lion Hospital pathology laboratory were evaluated. Cytological diagnoses was classified as benign, suspicious for malignancy, malignant, and inadequate or inconclusive and was compared with the histopathologic diagnoses obtained from incisional biopsy or mastectomy specimen to assess the diagnostic performance of FNA. Result and conclusion: The sensitivity and specificity of FNAc was found to be 86.7% and 90.3% respectively. FNA is still proved to be a good diagnostic modality for immediate diagnosis and patient follow up. The positive and negative predictive values are 86.7% and 90.3% respectively. masses of patients who underwent subsequent histopathologic evaluation during June2013-June2014 at Black lion Hospital pathology laboratory were evaluated.
