Eighth order Predictor-Corrector Method to Solve Quadratic Riccati Differential Equations

In this paper, the eighth-order predictor-corrector method is presented for solving quadratic Riccati differential equations. First, the interval is discretized and then the method is formulated by using Newton’s backward difference interpolation formula. The stability and convergence of the method have been investigated. To validate the applicability of the proposed method, two model examples with exact solutions have been considered and numerically solved. Maximum absolute errors are presented in tables and figures for different values of mesh size h and the present method gives better results than some existing numerical methods reported in the literature. &nbsp

Evaluating the application of human rights principles in crime investigation in Ethiopia : a case study of the Addis Ababba city police

In any society the police are organized with the responsibility of keeping peace and order, ensuring the rule of law, justice, prevention of crime as well as protection of human rights. Regardless of the circumstances in which the police find them, they should act towards every human being with a sense of duty and care for human rights; it is the responsibility of the police to conduct the process of arrest, search and seizure according to the law with no neglect of duties. The police are expected to comply with the arrest, search and seizure procedures designed to ensure the protection of human rights. Nevertheless, usually, the task of investigation is vulnerable to human right violation. This is particularly true in the case of the developing countries where the process of democratization is so infant that most of them not only lack the required level of awareness/understanding pertaining to the human right principles but also the necessary institutional mechanisms that contribute to the proper application of human right principles are missing. The report of the Ethiopian Federal Police Inspection Service conducted in the year 2003 indicated that there were some suspects arrested without court warrant and with the existence of reasonable doubt for their guiltiness. Moreover, findings of a research conducted in the same year on certain Addis Ababa sub-city police stations also clearly indicate this fact. The objective of the this research is to evaluate the extent to which crime investigator, who are duty bearers in the Addis Ababa city police, adhere to the human right principles pertaining to the rights of suspected, accused and arrested person that are recognized in pertinent international instruments and enshrined in the Federal Democratic Republic of Ethiopia (FDRE) constitution and other related laws of the country while fulfilling their duties and responsibilities throughout the crime investigation process. Specifically the study is also aimed at exploring the form and type of commonly violated human right, if any and the determinant factors behind the respective types of human right violation by crime investigation belong to the Addis Ababa police .Methodologically the study followed and is mainly relied on the qualitative empirical approach to social science research.Police PracticeM.

PREVALENCE OF PERCEIVED MORBIDITY IN ADDIS ZEMEN TOWN, ETHOPIA

ABSTRACT A morbidity interoiew-survey was conducted in Addis Zemen, North-Western Ethiopia. Four hundred (20%) of the households (1710 people) were randomly selected to praticipate in the survey, to test the recall of recent health problems during a four week period. 310 people (18%) of the sample reported health problems, particularly of the digestive, visual, musculoskeletal and respiratory systems. Morbidity varied with age and sex. There were relatively higher reports of morbidity in the preschoolage as well as during later life. There was also a preponderence of females ( 12%) versus males (6%) reporting illnesses as a consequence of which adults lost 0.65 days of work per month per person, estimated at 8.0 days per year. Only 7.9% of persons reporting illnesses were disabled for three or more days, while over half of those reporting illness utilized medical care, with a preference for modem medicine, 40% failed to utilize any fonn of medical care. The major reason given was cost

Assessment of knowledge, attitude and risk behaviors towards HIV/AIDS and other sexual transmitted infection among preparatory students of Gondar town, north west Ethiopia

<p>Abstract</p> <p>Background</p> <p>The first case of HIV in Ethiopia was reported in 1984. Since then, HIV/AIDS has become a major public health concern in the country, leading the Government of Ethiopia to declare a public health emergency in 2002. Although the epidemic is currently stable, HIV/AIDS remains a major development challenge for Ethiopia. The spread of HIV in any community is in part determined by the knowledge of attitude towards sexuality of its members and by their actual sexual practices. The aim of the study was to assess students' knowledge, attitudes and practices regarding HIV/AIDS and STDs in Gondar, North West Ethiopia.</p> <p>Methods</p> <p>A cross sectional study was conducted between February 1 to March 1, 2009 in preparatory high school students. Pre-tested questioner was used to generate the data and analysis was made by SPSS version 15. Chi -square value was calculated and p-value < 0.05 was considered statistically significant.</p> <p>Results</p> <p>All the students had heard about AIDS before the interview. Knowledge on some aspect of the disease was quite low in the study group. Only half of the students knew that at present, AIDs is incurable and that HIV infection can be acquired through sexual contact with a 'familiar' person. Knowledge about STI was also quite low, 39% knew that pus in the urine is a symptom of STI and 45.4% knew that acquisition of other STIs is increases the chance of HIV transmission following unsafe sex with known cases. 25% of the study group had previous sexual intercourse and exposed at least one risk behavior. About 34% of the respondents had negative attitude towards AIDS and STDs.</p> <p>Conclusion</p> <p>Awareness about STDs and methods of prevention of HIV and STDs was low. More risk behavior was observed in male and those with alcohol and drugs of abuse.</p

Implementation fidelity and challenges of optimal cold chain management in Assossa district health system, Benshangul-Gumuz region, Western Ethiopia

AbstractIntroduction: Preventive programs which have proven to be effective in clinical trials may not necessarily impact the health and wellbeing of the community unless they are implemented with fidelity. While cold chain is the backbone of immunization programs, limited studies exist to explain fidelity implementation which likely contributes to a lack of evidence-based instructional practices of cold chain management.Aim: This study aimed to explore the fidelity implementation and challenges of optimal cold chain management in the Benshangul-gumuz region.Methods: A qualitative approach was utilized to explore the underlying challenges to optimum implementation of cold chain management in Benshangul-gumuz region. Observational techniques and key informant interviews with 12 key-informants were conducted. Data was collected at all levels of the health system including, the regional health bureau, Ethiopian Pharmaceuticals Supply Agency hub, district health offices, Health centers, and health posts. Data analysis and interpretation was performed using the framework analysis approach. Open Code 4.02 software was used for analysis.Findings: This study identified three main themes including adherence to intervention, human resource development, and availability and use of resources. The findings also revealed that a significant number of the employees were not adhering to the optimal cold chain management guidelines. Staff development, availability and utilization of equipment and related finances were major fidelity implementation challenges of cold chain management.Conclusions: Across the health facilities under study, implementation fidelity of cold chain management was considered poor. Human resource development, proper allocation and effective management of logistics and related finance could facilitate optimal cold chain management practices, and efforts to save lives through delivery of safe and quality vaccines.

The Burden of Internal Conflict on Expanded Programs on Immunization in Northwest Ethiopia: Implementation Science Study

AbstractBackground: Despite the rapid progress in immunization service delivery systems worldwide, populations in areas of conflict often have limited or no access to lifesaving vaccines. Hence, evidence generation and translation for context-specific strategies and tailored action would be important, before, during and after an acute humanitarian emergency.Aim: To explore factors affecting immunization service delivery during and after conflict among internally displaced communities in Northwest Ethiopia.Methods: Qualitative and quantitative (record review) methods were applied, phenomenological study design and in-depth interviews were applied to collect the lived experiences of participants in the affected areas. Transcribed and translated data were analyzed and thematized using open code software. A Twenty-four-month record review of quantitative data was analyzed descriptively using an excel sheet to develop immunization coverage trends for tracer antigens.Results: We found that the immunization program had seriously deteriorated during and after the conflict in the study area. The monthly EPI service report in the affected areas showed a decline with the lowest records in December and January when the internal conflict was peak. Security problems, displacement of health workers, destruction of health infrastructures, mixing of the displaced community in the host community and poor coordination among stakeholders and partners, clients having other emergent needs and shortages of resources were important factors for immunization services.Conclusion: Vaccination service delivery was found to have significantly declined in the study area. Security problems affected not only the service utilizers but also the service providers’ wing as well. Coordination of stakeholders and strong leadership systems are crucial in maintaining optimum vaccination service delivery even at the time of conflict. [Ethiop. J.

How to optimize health facilities and community linkage in order to enhance immunization service? The case of West Amhara Region, Ethiopia

AbstractBackground: Health facility-community linkages are important in designing community-level interventions, appropriate immunization service provision modalities, and changing unhealthy behaviors. However, there is limited evidence on the influence of community and facility linkage on vaccination services in Ethiopia.Aim: This study aimed to explore how the linkage between health facilitiesa and the community could be optimized in order to enhance immunization services.Methods: A Phenomenological study design, using an explanatory approach was applied in the two districts (Shebele Berenta &amp; South Achefer district) of the Amhara region for the month of June , 2020. Forty-six key informants were interviewed using an interview guide and data was analyzed using open code version 4.02. The data was coded, and thematic analysis was applied.Results: The finding revealed that there were community platforms to facilitate community and health facility linkage. Respondents also perceived that the community to health facility linkage was an effective strategy for the Expanded Program on Immunization (EPI) service provision. The study revealed that perception of health care providers, health care providers attitude and practices, shortages of stock (medication and supplies), distance from main road and transportation, irregularity in the implementation of rules and regulations, lack of incentives, inadequate counseling and support, lack of awareness, shortages of human resources and lack of training support for health care workers were barriers for effective community-health facility linkage.Conclusion: The linkage of community and facilities were not approached in the same manner within districts and facilities. Therefore, strengthening a common system for community-health facility linkage and community engagement is critical during immunization services. Establishing a strong strategy of incentivizing mechanisms is vital for the effective implementation of immunization services. An advocacy strategy to mobilize engagement among policy and decision-makers, and other key stakeholders was an important strategy for improving the program. [Ethiop. J.

Assessment of barriers to the implementation of community-based data verification and immunization data discrepancies between health facilities and the community in Tach Gayint district, Northwest Ethiopia.

AbstractIntroduction: While community-based data verification (CBDV) is critical for effective implementation of immunization programs, limited evidence exists detailing its implementation at the local levels thereby threatening data quality which is used to guide decision making.Aim: To explore the barriers to proper implementation of CBDV and determine the level of immunization data discrepancy between the health facilities and community levels in Tach Gayint district of Northwest Ethiopia.Methods: A Mixed methods approach was used. Interviews with twenty-six key informants’ (health experts) in immunization data, and an additional a sample of 324 infants were recruited. All health centers in the district (6) and 2 health posts from each health center (12 in total) were selected using Simple Random Sampling. Key informant interviewees were purposely included from all health facilities. For quantitative data, samples of infants were proportionally allocated for each health facility as per their DPT/Pentavalent-1 vaccine report. Thematic analysis of the qualitative data and descriptive quantitative analysis were performed using statistical software open-code v-4.02 and STATA v14.1 respectively.Results: Only few health facilities implemented CBDV and consider it to be their routine task. Also, barriers to effective implementation of CBDV such as lack of prioritization, poor capacity among health staff, and conflicting job roles were identified. The highest immunization data discrepancy among community and health facilities was observed for the measles-one vaccine (35.4%), and the minimum was for DPT/Pentavalent-1 (25.6%).Conclusion: This study revealed a poor level of CBDV implementation and barriers to its effective implementation which include lack of prioritizing CBDV, limited capacity among health staff in performing CBDV, and conflicting job roles among health staff. There was a high level of immunization data discrepancy for measles-1 and DTP/Pentalent-3 vaccines. Based on our finding, we make the following recommendations: building skills among health workers to perform CBDV, enhancing availability and use of standard CBDV tools, ensuring monitoring, and control mechanism, and setting clear definition of roles regarding CBDV, as well as closing the gap in level of immunization data discrepancy could help foster effective implementation of CBDV.
