Mathematical Models for Influenza a Virus and Pneumococcus: Within-Host and Between-Host Infection
(Pan African University Institute for Basic Sciences, Technology and Innovation, 2019-04) Kamugisha, Mbabazi, Fulgensia
Infectious diseases have become problematic throughout the world, threatening individuals who come into contact with pathogens responsible for transmitting diseases. Pneumoccocal pneumonia, a secondary bacterial infection follows an influenza A infection, responsible for morbidity and mortality in children, elderly and immuno–comprised groups. The aims of this Thesis are to; develop a mathematical model for within–host co–infection of influenza A virus and pneumococcus, model between–host pneumococcal pneumonia in order to determine the effect of time delays due to latency and seeking medical care, and study the effect of antibiotic resistance awareness and saturated treatment in the control of pneumococcal pneumonia. Analysis of the stability of steady states of influenza A virus and pneumococcal co–infection, pnemococcal pneumonia with time delays and antibiotic resistance awareness is done. The graph theoretic method, combined linear and quadratic Lyapunov functions, Goh–Voltera Lyapunov function are used to get suitable Lyapunov functions for global stability of steady states. The results show that the endemic equilibrium of pneumococcal pneumonia is locally stable without delays and stable if the delays are under conditions. The results suggest that as the respective delays exceed some critical value past the endemic equilibrium, the system loses stability and yields Hopf–bifurcation. The results of influenza A virus and pneumococcal co–infection show that, there exist a biologically important steady state where the two pathogens of unequal strength co–exist and replace each other in the epithelial cell population when the pathogen fitness for each infection exceeds unity. The impact of influenza A virus onto pneumococcus and vice–versa yields a bifurcation state. The results show that, the presence of antibiotic resistance awareness and treatment during the spread of pneumococcal pneumonia drastically reduces the basic reproduction number R0 to less than unity, hence the disease could be eradicated.

Police, in the quest to keep law and order, handles issues manually. Once an issue is forwarded, it is recorded in the personal books that act as files for each individual; this is then captured in the central store which in all cases is a black book. Calls are then made using radio calls to make reports and a number of communications to other police stations. This process is time consuming, leads to data loss and does not maintain data integrity and security. A service desk will address all of the above mentioned problems. The researchers set to develop an Intranet Based Police Service Desk for Uganda Police to solve the problem above. This was in the effort to provide efficiency in police undertakings. In order to get information about the existing system, questionnaires, interviews and observations were conducted with top police officials to get a clear picture of how police operates, get user and system requirements needed for the proposed system. The Records Manager Mr. Okeleng John at the Police headquarters in Kampala and the District Police Commander (DPC) of Wandegeya Police Station were the main respondents during the study. Data Flow Diagrams, Entity Relationship Diagrams and context diagrams were the tools used in the design of the system. A database was developed to enhance dynamic interactivity and information storage of captured information. A Website was also developed to act as a user interface and sample screen shots of the interfaces were presented as well as reports generated from the system. In a nutshell, basing on the findings of the study like increased efficiency in Police operations, increased accessibility to information, improved communication, teamwork, enhanced focus and creation of a proactive approach to service provision, it is therefore advisable that Police implements the Intranet Based Police Service Desk.
Goal Models Vs Five Forces Models: A Comparative Study of Strategic Analyses
(University of Trent, 2015) Kasozi Musanje, Joseph Brian
The performance of an enterprise is determined by its strategic objectives, and the strategic plan it adopts through some form of strategic analysis in order to meet these objectives. However, strategic analysis is currently only supported through unsystematic and informal processes such as SWOT analysis and the Five Forces Model. This thesis proposes conceptual goal modeling as a systematic approach to strategic analysis and shows through a comparative study how this analysis can be conducted for a Goal Model and the Five Forces Model. The study is conducted through a case study adopted from the literature.
Designing an Architecture for Secure Sharing of Personal Health Records - A Case of Developing Countries
(2014) Ssembatya, Richard
While there has been an increase in the design and development of Personal Health Record (PHR) systems in the developed world, little has been done to explore the utility of these systems in the developing world. Despite the usual problems of poor infrastructure, PHR systems designed for the developing world need to conform to users with different models of security and literacy than those designed for developed world. This study investigated a PHR system distributed across mobile devices with a security model and an interface that supports the usage and concerns of low literacy users in developing countries. The main question addressed in this study is: “Can personal health records be stored securely and usefully on mobile phones?” In this study, mobile phones were integrated into the PHR architecture that we/I designed because the literature reveals that the majority of the population in developing countries possess mobile phones. Additionally, mobile phones are very flexible and cost efficient devices that offer adequate storage and computing capabilities to users for typically communication operations. However, it is also worth noting that, mobile phones generally do not provide sufficient security mechanisms to protect the user data from unauthorized access. The research question was addressed through a systematic review of healthcare systems, a survey of healthcare consumers and providers, and usability experimentation. The review of health systems was conducted to refine the problem. A survey of end-users (patients and healthcare givers) was carried out, and the findings were useful in understanding the current state of practice of personal health records, understanding patients’ needs and requirements, and deciding on the components of the PHR system to be implemented. The design, development, implementation and evaluation of the PHR system were achieved through a Patient-Centred Design (PCD) approach and Human Access Points (HAP) technique. Data security was implemented by incorporating in addition, an Identity-Based Encryption (IBE) architecture. The laboratory evaluation results of the mobile phone-based PHR system demonstrate that the proposed IBE can be extended to mobile phones to secure PHRs beyond the hospital’s server domain. Additionally, the usability evaluation results reveal that the system is useful to patients in: supporting their memory; confirming personal health records and accuracy; learning about their conditions regularly; and minimising medical jargons. Moreover, none of the medical practitioners reported any concern. Instead, the medical practitioners recalled their experience with the system in a positive light: supports medical-decision making; improves relationship with their patients; xvi and provides continuity of patients’ care when the healthcare server is offline due to frequent power outages and/or unreliable Internet connections.
Description of Continuing Professional Development Practices in Amolatar District.
(Uganda Martyrs University, 2012) Otile, Patrick
OTILE PATRICK (2012-M121-10028) Description of Continuing Professional Development Practices in Amolatar District Continuing Professional Development (CPD) is the way professionals continue to learn and develop throughout their careers so that they keep their skills and knowledge up-to-date and are able to work safely, legally and effectively. CPD is expected to have many advantages among them; improving the 13 knowledge and skills of health workers, motivating them to be more committed to their work and improve overall performance. It can be achieved through personal study, clinical/ professional meetings, workshops, conferences, conventions and supervision. Due to the importance attached to CPD, several efforts and resources (material & non-material) have been devoted by government (Ministry of health, districts, health facilities) and other development partners in support of CPD for health workers. However, little effort or deliberate measures have been undertaken to ascertain whether the resources devoted to CPD actually derive some benefits to the health workers or not. The goal of this study was to describe the CPD practices among health workers in Amolatar district and ascertain the perceived benefits from the CPD practices. The specific objectives of this study included: assessing the extent of participation of health workers in CPD in Amolatar district, examining the different forms of CPD practiced by health workers in Amolatar district, establishing the available factors enhancing effective execution of CPD and identifying benefits health workers associate to the CPDs they practice. Data collection was guided by the research objectives whereby the researcher applied descriptive, cross-sectional study design employing both quantitative and qualitative approaches so as to derive meanings from data that was generated. The research instruments used to obtain data during this study included administration of Likert scale questionnaires and interview guide. Document reviews were used for triangulation purposes with data collected using the other tools mentioned above. Respondents for the study were selected from the health facilities using proportionate to size sampling technique and key informants purposively selected from the District Health Office, considering their stake, knowledge and experience on the variables of study. All the eleven health facilities in Amolatar district were reached during this study. Key Words: Description, Continuing, Professional Development Practices, Amolatar Distric.
