- ItemInternet of things based visualisation of effect of air pollution on the lungs using HEPA filters air cleaner(Heliyon, 2023-07-03) Katushabe, Calorine; Santhi, Kumaran; Masabo, EmmanuelThe impact of air quality on human health and the environment is very significant, with poor air quality being responsible for numerous deaths and environmental damage worldwide. Whereas a number of studies have been done to monitor the quality of air with help of emerging technologies, little has been done to visualize its effect on health particularly on the lungs. The study explores an approach that combines Internet of Things (IoT) technology with High Efficiency Particulate Air (HEPA) filters air cleaner to monitor and visualize the effects of air pollution on lung health, highlighting the significant damage that poor air quality causes particularly on the lungs graphically. To achieve this, a 3D display of the lungs is modelled using HEPA filters, which changes colour based on the air pollutant concentrations detected by IoT based sensors. The collected air quality data is then transmitted to Thingspeak, a visualization platform for further analysis. It is observed that the colour of the 3D lung display changed to black over time as air pollutant concentrations increased which in our study is an indicator of unhealthy lung. The study presents an innovative approach to visualize the effects of air pollution on lung health using IoT and HEPA filters air cleaner, which could have significant implications for public health policies aimed at mitigating the harmful effects of air pollution, particularly on lung health.
- ItemMasked and Unmasked Face Recognition Model Using Deep Learning Techniques. A case of Black Race.(Kabale University, 2023) Mabirizi, Vicent; Ampaire, Ray Brooks; Muhoza, Gloria B.Currently, many institutions of higher learning in Uganda are faced with major security threats ranging from burglary to cyber threats. Consequently, the institutions have recruited and deployed several trained personnel to offer the desired security. As human beings, these personnel can make errors either by commission or omission. To overcome the limitation of trained security personnel, a number of face recognition models that detect masked and unmasked faces automatically for allowing access to sensitive premises have been developed. However, the state -of -the art of these models are not generalizable across populations and probably will not work in the Ugandan context because they have not been implemented with capabilities to eliminate racial discrimination in face recognition. This study therefore developed a deep learning model for masked and unmasked face recognition based on local context. The model was trained and tested on 1000 images taken from students of Kabale University using Nikon d850 camera. Machine learning techniques such as Principal Component Analysis, Geometric Feature Based Methods and double threshold techniques were used in the development phase while results were classified using CNN pre-trained models. From results obtained, VGG19 achieved the higher accuracy of 91.2% followed by Inception V 3 at 90.3% and VGG16 with 89.69% whereas the developed model achieved 90.32%.
- ItemAn Investigation into Information Security Managerial Practices in Selected Public Sector Organizations.(Kabale University, 2023) Ahimbisibwe, Benjamin K.; Nabende, Peter; Musiimenta, FlorenceThe study aims to examine information security managerial practices in organisations. It was guided by three specific objectives: identification of information security practices critical to information assets management; establishment of implementation processes involved in the execution of structured information security governance; and evaluation of policies that influence information security best practices. In line with these objectives, security was acknowledged as a requisite element in protecting organizational information assets. The study covered two public sector organisations specifically, Uganda Wildlife Authority and National Forestry Authority. Focus was made on information security practices critical to managing information like human security, information classification, procedures for information labelling, compliance, standards, command and control techniques. These security practices were selected based on their importance in the protection of confidentiality, integrity and availability of information assets. Descriptive research design was adopted to describe the phenomenon under study. Being an in-depth inquiry, qualitative approach was used, survey questionnaires representing zero and one scores were designed to collect data. The respondents were purposively selected based on their knowledge in the subject area, cost-effectiveness and delivery of timely results. These respondents included information technology officers, administrative secretaries, data clerks and security guards. Findings from the field were analyzed and presented in meaningful tables. The research findings demonstrate that evaluation of users’ actions was hierarchical in nature; based on associations with tasks performed; information security practices are not aligned to guidelines set by National Information Technology Authority; there was need to establish appropriate measures to handle new information security risk in organizations. Based on these findings, recommendations that reflect the importance of examining information security managerial practices in organizations were made.
- ItemE-Book Mobile Application: A Case of Kabale University Mukombe Library, Uganda(East African Journal of Information Technology, 2022) Clare, Ninsiima; Patricia, KyomugishaGlobally, many academic e-books are available in user-friendly forms like PDF and HTML that can be accessed on laptops, iPads, and smartphones, even though some e-books require a special e-book reader. However, university students find it difficult to access e-books because some of the university libraries have few computers that hold the downloaded e-books, which are stored in a folder, and little effort has been made as a result; there is low usage of e-books. The project’s goal was to investigate how e-book applications work and how students at Kabale University can access e-books via mobile phone or tablet. The objectives of the project were to investigate the existing e-books application, design and develop the e-books application, and test and validate the developed application that enables students at Kabale University to access e-books simultaneously. The literature review helped me read a number of pieces of literature about e-book applications. They were information sources about the E-books application such as the internet, books, journals, and newspapers, among others. The use of existing information from the library helped to develop a model to predict the E-book application and testing of the application using Android smartphones. It was concluded that the implementation of the e-book’s application was done using Android to enable users to access the books on their mobile phones or tablets. The study recommends that the administrator of the system should be taken through the tasks in order to be able to upload books ready for the application
- ItemA Mobile Based Technology to Improve Male Involvement in Antenatal Care.(Kabale University, 2022) Gloria, Muhoza B.; Mukasa, Ssemaluulu Paul; Mabirizi, VicentThe World Health Organization Technical Working Group on maternal health unit recommended a minimum level of care to be four visits throughout the pregnancy for pregnant mothers [1]. The first visit which is expected to screen and treat anaemia, syphilis, screen for risk factors and medical conditions that can be best dealt with in early pregnancy and initiate prophylaxis if required (e.g., for anaemia and malaria) is recommended to be made before the end of the fourth month of pregnancy. The second, third and fourth visits are scheduled at 24–28, 32 and 36 weeks, respectively. Male involvement in Antenatal health care has been described as a process of social and behavioral change that is needed for men to play more responsible roles in maternal health care with the aim of ensuring women and children’s wellbeing. A study by Okoth [1] reported that, in Uganda male involvement in antenatal care stands at only 6% and this has been attributed to social, economic and cultural related factors. The situation worsens with the lack of effective coordinated platform for males sharing their experience in taking part in ANC and this has affected the process of antenatal care service delivery. Objective. To assess the role of mobile technology to improving male involvement in antenatal care by developing a mobile based technology which sends SMS reminders to male partners encouraging them to escort their pregnant wives for antenatal care services. Research questions. What are the challenges towards the limited antenatal care seeking behaviours among pregnant mothers? What are the causes of limited male involvement in antenatal care? What roles do ICTs play in enhancing Antenatal Care seeking behaviours among pregnant mothers and in increasing the male involvement in Antenatal Care? Method. We purposively selected pregnant mothers who phones, had been receiving antenatal care services from Kabale general hospital and reported staying with her male partner. The recruited participants were interviewed together with their male partners. STATA 13 software was used to define participants’ demographic while qualitative data were analysed using content analysis to come up with classes describing participants’ perceptions. Results. Participants reported that reminding them of their next antenatal visit via SMS reminder plays a significant role towards their antenatal care seeking behaviour. Conclusion. Mobile health could be a potential approach to improving male involvement in antenatal care through sending timely SMS reminders to both the expectant mother and her male partner remaining them of their next antenatal visit.
