Abstract: Background- Breastfeeding and good nutrition for children are essential for achieving the Millennium Development Goals, particularly the goals relating to child survival. Even though, most mothers in Ethiopia breastfeed their babies, they do not always follow the recommendations of the "National Strategy for Infant and Young Child Feeding". Objective- The aim of this study was to assess determinants of breastfeeding practices among mothers’ of children aged less than 24 months attending governmental maternal and child health clinics in Mekelle town.Methods- Institution based cross sectional study was carried out among five health facilities selected using simple random sampling technique. Data was collected by interviewer administered structured questionnaire and it was entered, cleaned and analyzed by using SPSS for windows version 16.0. The proportion was used to describe the results and it was presented in the form of figures, tables and texts. The binary logistic regression model was used to test the association between dependent and independent variables. Result- A total of 361 mothers with their index child were interviewed. The ever breastfeeding rate in this study was 98.9%. The timely initiation rate of breastfeeding and exclusive breastfeeding were 77.9% and 60.8%, respectively. Conclusion and recommendation-: A range of characteristics affects the practice of timely initiation of breastfeeding and exclusive breastfeeding. Coordination, strengthening, sustaining of the existing strategies and approaches for further improvement of optimal breastfeeding practice is recommended.

This study was conducted to examine problems that challenged academic performance of physics students in higher governmental institutions in the case of Arbaminch, Wolayita Sodo, Hawassa and Dilla Universities. Questionnaires, interviews and video recordings were used to collect relevant data for the study. Data from questionnaires was compiled and analyzed using a computerized data analysis package known as Statistical Package for Social Science SPSS 17.0. The Pearson chi-square test was used to compute to test association between dependent variable and independent variables and T-test was used to find out how academic performance varied with interest to subject matter. On the other hand, ANOVA test was used to test variation of the academic performance in study sites. Besides, percentages were used for comparison of data analysis. The findings reveal the existence of a significant influence of teachers both in fostering positive or negative attitude to subject (physics) and for their poor academic performance in lower class as well as in higher institutions. On the basis of the findings, the least percentage of students (16%) indicated that their current department was the best choice for them during application for admission. Whereas the highest percentage (84%) of sample class students was enrolled in department of physics without their interest and the academic performance (ESELS result), the highest percentage (70) of students who were admitted to department of physics was below 50%. The p values 0.01 and 0.00, respectively for students who are enrolled in department of physics with best choice and without their interest, are less than alpha level of significance (0.05), which reveals that, there is statistical significance academic performance deference between students in both cases. However, the difference is more significant for those students who are enrolled without their interest. By analysis of Pearson chi-square test summary in respective study sites, the p values 0.01, 0.007, 0.021 and 0.022 respectively are less than the alpha (α) level of significance of 0.05, which reveals that there is strong association between those variables. In the other corner of the ANOVA test analysis indicates that p value 0.01 is less than alpha level of significance 0.05. This reveals variation of academic performance of students between four higher governmental institutions where the study is made.

Berry Approach to Intrinsic Anomalous Hall Conductivity in Dilute Magnetic Semiconductors (Ga1-xMnxAs)  [PDF]
Sintayehu Mekonnen, P. Singh
World Journal of Condensed Matter Physics (WJCMP) , 2015, DOI: 10.4236/wjcmp.2015.53019
Abstract: We develop a model Hamiltonian to treat intrinsic anomalous Hall conductivity in dilute magnetic semiconductor (DMS) of type (III, Mn, V) and obtain the Berry potential and Berry curvature which are responsible for intrinsic anomalous Hall conductivity in Ga1-x MnxAs DMS. Based on Kubo formalism, we establish the relation between Berry curvature and intrinsic anomalous Hall conductivity. We find that for strong spin-orbit interaction intrinsic anomalous Hall conductivity is quantized which is in agreement with recent experimental observation. In addition, we show that the intrinsic anomalous Hall conductivity (AHC) can be controlled by changing concentration of magnetic impurities as well as exchange field. Since Berry curvature related contribution of anomalous Hall conductivity is believed to be dissipationless, our result is a significant step toward achieving dissipationless electron transport in technologically relevant conditions in emerging of spintronics.
Patterns of maternity care service utilization in Southern Ethiopia: Evidence from a community and family survey
Yared Mekonnen
Ethiopian Journal of Health Development , 2003,
Abstract: Background: Despite the fact that maternal health care utilization is essential for improvement of maternal and child health, little is known about the level and patterns of use of the service in Ethiopia. Objective: This study examined the levels and patterns of maternity care service use in the five densely populated zones of the Southern Region of Ethiopia. Data and Method: The study utilized data collected in a Community and Family Survey (CFS), which was conducted between early May and early June 1997. The CFS was cross-sectional by design and for this particular study a total of 1401 women who had at least one live birth in the six years preceding the survey were included. Result: The study revealed that only 26.1 % and 3.3% of the women received antenatal and delivery care services, respectively. The probability of a woman having an antenatal care for her most recent birth was 0.280, but this was significantly higher if she had received a check-up for her previous birth (0.787). On the other hand, the probability of having received delivery care for the most recent birth given that the woman had attended for her immediately preceding birth was only 0.468. The study also revealed that the use of both antenatal and delivery care services for subsequent pregnancies is less apparent among those women with more than one under-five children and those residing in the rural parts of the study area. Conclusion: To improve coverage of maternity care services in the study area health planners need to focus not only on those women who never utilize the services but also those who are not consistent in their use.

Liquid waste management: The case of Bahir Dar, Ethiopia
FH Mekonnen
Ethiopian Journal of Health Development , 2012,
Abstract: Background: Human beings pollute the environment with their industrial and domestic wastes. In Bahir Dar Town there is no conventional municipal waste water collection and treatment system. Objective: The aim of this study was to describe the liquid waste disposal practices of the residents of Bahir Dar Town and to assess the performance of waste water disposing institutions. Methods: Data were collected from 270 households and 16 experts working in liquid waste management institutions. Different closed and open ended structured questionnaires were prepared to collect the data from the samples. Results: Sixty-four percent of the respondents discharge their waste water in to the streets and open fields. The inadequacy of sanitation services resulted in defecating in open fields and discharging of raw waste water into inappropriate places and these, in turn, have created serious environmental problems. Conclusion: There is a weak implementation of the regional sanitation regulations in Bahir Dar. Controlling offenders through strict enforcement of the regulations should be encouraged. Skilled environmental health workers should be assigned at each kebele and sub-city to implement sanitation regulations and coordinate the sanitation efforts at the grassroots levels. [Ethiop. J.

Missed opportunity of tetanus toxoid immunization among pregnant women in Southern Ethiopia
Yared Mekonnen
Ethiopian Journal of Health Development , 2000,
Abstract: This study attempted to assess the presence of missed opportunity for tetanus toxoid immunization using a Community and Family Survey (CFS) data collected in the five densely populated zones of the SNNPR. The study established the existence of a true missed opportunity for tetanus toxoid immunization among antenatal clients after examining the data for possible sources of biases. A bivariate and multivariate analysis using logistic regression model suggested the absence of both recall and life long protection biases in the data. Accordingly, 11.6% of the women represented a true missed opportunity for tetanus toxoid immunization in the study area. The level of missed opportunity was found to be about 13% in the rural area as compared to only 4% in the urban parts of the study area. Missed opportunity was also high among those women who initiated antenatal visit in their third trimester of pregnancy and those women who had only one visit in the whole course of pregnancy. In the light of the findings, in-depth operational studies are recommended to better understand the reasons behind missed opportunity for tetanus immunization in the study area.

Indigenous legal tradition as a supplement to African transitional justice initiatives
D Mekonnen
African Journal on Conflict Resolution , 2010,
Abstract: This article interrogates the role of indigenous legal tradition (ILT) in contemporary African transitional justice initiatives. It departs from the assumption that most African cultures put emphasis on communality and the interdependence of the members of a community. Indigenous legal traditions, which include mechanisms for acknowledgement, truth telling, accountability, healing and reparations, continue to assume a prominent role in the lives of African societies and individuals. However, little attention has been given to the role of African indigenous legal tradition in terms of its contribution to postconflict transformation. Several African societies have deeply rooted social and communal values of conflict resolution which can serve as a reservoir of wisdom in future transitional justice initiatives. In furtherance of the main theme, the article discusses an example of ILT from Eritrea, and calls for a continued engagement and critical assessment of these values in promoting peace and justice in Africa.
From Tenuous Legal Arguments to Securitization and Benefit Sharing: Hegemonic Obstinacy – The Stumbling Block against Resolution of the Nile Waters Question
DZ Mekonnen
Mizan Law Review , 2010,
Abstract: Resolution of the Nile waters question has proved, once again, to be an elusive task. Identifying the major hurdle which has bedeviled past cooperative initiatives and rendered current efforts mere Sisyphean ones is thus of paramount importance. The main thrust of this article is to identify this challenge which has thus far stifled almost all efforts at resolution of the Nile waters question in a fair and equitable manner. The consistently obstinate position Egypt has taken over the years to maintain its poignantly inequitable “share” of Nile waters forever is the heart of the problem which makes any settlement of the Nile waters question a virtual impossibility. Relying on its status as the basin’s hydro-hegemon, Egypt has so far been able to not only defend the indefensible but has also been able to effectively hoodwink and contain the non-hegemonic riparians by engaging them in “cooperative initiatives” and a “benefit sharing” scheme it effectively is using as stalling tactics while aggressively pursuing giant hydraulic projects as instruments of resource capture. A real transformation and a breakthrough in this stalemate requires, of necessity, a change in the malign, oppressive nature of Egyptian hydro-hegemony into a benign, cooperative one, at least. The non-hegemonic riparian states have thus to adopt effective counter-hegemonic strategies in order to force Egypt back to the negotiation table, developing, in the mean time, the resource and technical capability that would enable them to resist and overcome the multifaceted pressure and influence the hydro-hegemon will inevitably exert to keep them in line; failure to do so would surely condemn them to live, ad infinitum, with the grotesquely inequitable status quo.
Leech infestation: The unusual cause of upper airway obstruction
D Mekonnen
Ethiopian Journal of Health Sciences , 2013,
Abstract: This paper presents a case of a 7 year-old child who presented with a 14-days history of blood stained saliva and shortness of breath of 3 days with signs of upper airway obstruction. Laryngoscopy revealed a blackish living foreign body in the proximal trachea. Under general anesthesia the leech was removed by applying forceps. I conclude that a high index of suspicion of leech infestation is required when faced with a child presenting with unexplained bleeding per mouth and signs of upper airway obstruction. KEY WORDS: Leech, Foreign body, Trachea, upper airway obstruction.
