    Framework for PKI Implementation: Optimizing Project Management in Ethiopia
    (Addis Ababa University, 2024-09) Binyam Ayele; Henock Mulugeta (PhD)
    In today's increasingly digital world, the security of online communications and transactions is paramount. Public Key Infrastructure (PKI) has emerged as a cornerstone technology for ensuring secure, authenticated, and confidential digital interactions. However, the implementation of PKI projects remains challenging due to its inherent complexities, including certificate management, key distribution, and system integration, National legal framework contradictions & Limitations, lack of interoperability. The lack of a standardized implementation framework further exacerbates these challenges, leading to inconsistent and often flawed deployments that fail to leverage the full potential of PKI. This study investigates the importance of optimizing a PKI Project implementation framework that support the establishment of a national or organizational PKI project at national or organizational level by developing a comprehensive framework that mitigate PKI project implementation challenges. The study seeks to address the critical need for a comprehensive PKI Project Implementation Framework that can guide organizations in navigating the complexities of PKI deployment. The problem under investigation is the absence of standardized and generic framework and best practices for PKI implementation, which has resulted in varied levels of security and effectiveness across different sectors. The study aims to develop a framework that is adaptable to diverse organizational contexts, ensuring that PKI systems are implemented in a manner that is both secure and scalable. To achieve this goal, a systematic literature review (SLR) methodology will be employed as the primary research method. The SLR will systematically identify, evaluate, and synthesize existing research on PKI implementation, focusing on the challenges, best practices, and potential solutions proposed in the literature. By analyzing a wide range of studies, the SLR will provide a comprehensive understanding of the current state of PKI implementation and identify gaps that the proposed framework can address. This method will ensure a rigorous and evidence-based approach to the development of the PKI Project Implementation Framework. This research focused on developing a PKI implementation framework that assist PKI project management. A case study and Key Performance Indictor (KPI) is incorporated to evaluate the proposed framework. As a direct outcome of this study, stakeholders who have plans to implement PKI within Ethiopia or other country will obtain a proactive understanding of potential implementation considerations that should be taken.

    Prevalence of Cervical Spondylosis and its Associated Factors Among Symptomatic Adult Patients Attending Referral hospital in Ethiopia 2023
    (Addis Ababa University, 2023-01-24) Beyan Abduljewad; Binyam Ayele
    Background: Cervical spondylosis is a comprehensive term that describes age-related chronic degenerative diseases that result in neck pain, tingling in the arms, and possible myelopathic-associated paralysis. Methods and Materials: The study was conducted at the Tikur Anbessa Specialized Hospital (TASH) neurology and rheumatology clinic from May 1, 2022, to December 30, 2022. A 2-year retrospective hospital-based design was implemented. The source population was all spondylosis patients. The study population was all cervical spondylosis patients with complete clinical and imaging data from January 2020 to January 2022, and a total of 339 were selected randomly. Data was collected using the Open Data Kit and the internet-based Kobo Toolbox and analyzed using SPSS version 26. Mean, median, and standard deviation for continuous data and a frequency table for categorical data A bivariate and multivariate logistic regression analysis was carried out to see the association between dependent and independent variables. Statistical significance was considered at a level of 5% significance and an adjusted odds ratio (AOR) with a 95% CI. Result: During the study period, 2176 degenerative spinal disease patients were diagnosed. Of these, the medical records of 339 cases were taken using simple random sampling. Among study participants, 189 (55.8%) were female and 150 (44.2%) were male. The mean age of patients was 54.9 years, with an SD of 10.044. The prevalence of cervical spondylosis was 97 (28.5%), which is the second most common next to lumbar spondylosis (199.5%). 40 (11.8%) had both cervical and lumbar spondylosis, and 3 (0.9%) had thoracic spondylosis. The odds of having cervical spondylosis among females were higher with an AOR of 2.959 (CI: 1.445–6.060; p =.003), and the age group between 40 and 59 was also higher with an AOR of 2.011 (CI: 1.164–6.240; p =.000); smokers with an AOR of 2.02 (CI: 1.843–11.0242; p =.008); and current alcohol intake with an AOR of 2.83 (CI: 1.520–6.0) Conclusion: The prevalence of cervical spondylosis (CS) was relatively high compared to the reported literature. In Korea, Bangladesh (Punjab), India (population), China, Nigeria, and Sweden, the prevalence was: 47.8, 47, 17.2, 13.8; 10.7; and 0.035 percent, respectively. The risk of CS increases with age in both sexes, and females were once mostly affected by cervical spondylosis.
