An Online Hypertension Risk Monitoring System
Get PDFHigh Blood Pressure is a key risk factor for chronic kidney disease, haemorrhagic stroke, ischaemic stroke, heart failure, myocardial infarction, early death, and cognitive decline. It is still a problem for worldwide public health. The threat of hypertension and related disorders will be significantly reduced with early detection of hypertension and raising awareness. Having a web-based system will bring solutions to reducing its devastating effects on health. This study developed a hypertension risk monitoring web-based system that can be accessed by authorized medical practitioners and patients. The unified modeling language (UML) tools were used to design the system, and Web 2.0 technologies, MySQL, HTML, PHP, XML, Java, and CSS were used in its implementation. The local host Web-Apache-MySQL-PHP (WAMP) server was used to host the web-based hypertension risk monitoring system (BP_HRMSystem). Utilizing previously gathered hospital data for testing, the deployed system produced 100% accuracy. To offer reliable, fast, and comprehensive information regarding hypertension, it would be crucial to adopt this approach for monitoring hypertension risks. Medical practitioners and patients can use this hypertension risk monitoring system to identify, classify, diagnose, and manage hypertension and associated risk
Graphical Processing Unit and Central Processing Unit Performance in Human-Computer Interaction
Get PDFThe Graphical Processing Units (GPU) and Central Processing Units (CPU) performance in Human-Computer Interaction (HCI) has improved in recent years. Many researchers have worked in comparative analysis of GPU and CPU, but a lacuna was discovered in the area of importance of HCI-which is securing user satisfaction. This paper aims to review the performance evaluation of CPU and GPU systems. Questionnaire and experimental models were used for evaluation. Questionnaires were distributed to evaluate the level of user satisfaction, using demands and usability parameters. In experimental models, tools of evaluation were downloading PDF and textfiles. Parameters used to assess satisfaction were speed, storage capacity and execution time. The results of the evaluated performances on GPU and CPU systems based on the evaluation parameters were derived from the questionnaire and experimental data. Questionnaire results have shown that a lesser number of users demand GPU due to its high price, and a large number of users demand CPU due to its low cost of finance, despite its disadvantages. Based on the experimental model, resources were tested for two weeks with different test data and environments which showed that the GPU works faster than the CPU in terms of speed and storage capacity. The results of the functionality and performance level of the two processors showed how GPU obeys the laws of the user interface design principle and satisfied the importance of HCI by securing user satisfaction. Users in the area of Photography, Cinema, Film Production companies, etc. should be engaged with the use of GPU than CPU systems
REVITALIZATION OF HIGHER EDUCATION FOR SOCIO-ECONOMIC EMANCIPATION IN NIGERIA
Get PDFSocio-economic development is the primary goal of every well-meaning government, and it is essentially dependent on the level of economic activities in a country. There is no doubt about the fact that Nigeria socio-economic activities is confronted with daunting challenges and this includes poverty, insecurity, high rate of unemployment, banditry, low industrial output, unstable and deteriorating exchange rate, high inflation rate, inadequate physical and social infrastructure, very large domestic debt, and rising stock of external debt among others. Socio-economic emancipation relies on quality of human capital resource and this is a product of higher education in Nigeria. The contribution of Nigerian higher education is crucial if the country is to witness an increase in socio economic emancipation. Regrettably, a close look at the Nigerian higher education reveals that it is confronted with myriads of problems, which made it impossible to achieve the goal of contributing to socio-economic development of the country. This paper suggested ways of revitalizing higher education for socio economic emancipation in Nigeria. Suggestions raised include that government should ensure larger percentage of her budget is allocated for higher education, while every stakeholder should rise up to fund higher education so as to achieve socio-economic emancipation in Nigeria. Also, higher institutions should put in place strategic plan for impacting employability skills in their students, so as to prepare them for the tasks of life after schooling
ESTABLISHING THE NEXUS BETWEEN WOMEN, SECURITY AND PEACEBUILDING IN NIGERIA
Get PDFSecurity is the defense, policing, and intelligent functions of states, and the management of threats to the breach of peace through multilateral and bilateral processes. Security is often used to imply safety or freedom from danger and protection from external attack or infiltration. It is also a state of mind of the individual that is confidently secured of his/her well-being. Nigeria today lives in socially functional challenging times that make the state to be in a state of terror and has become quite paranoid and fearful of flying, of going to certain places, and fearful of certain people. These insecurity indices informed Nigerian search security, peace, and peace building through various methods that have yielded minimal positive results. Using the structural-functional theory, the paper qualitatively provided answers to questions such as: What roles can women play in curbing insecurity in Nigeria? To what extent has the women’s roles and position been utilized by the Nigerian government in peace and security? To what extent have previous security strategies of government worked without women's involvement? The paper revealed that without the adequate engagement of women in the management of insecurity the Nigerian search for a secured Nigeria may not yield the desired result. Women are veritable tools in the development of peace and security and should therefore not be neglected
