Doctors, researchers, and specialists are working on new-fangled methods to detect COVID-19 relatively efficiently, such as constructing computerized COVID-19 detection systems. Medical imaging, such as Computed Tomography (CT), has a lot of opportunity as a solution to RT-PCR approaches for quantitative assessment and disease monitoring. COVID-19 diagnosis based on CT images can provide speedy and accurate results. A quantitative criterion for diagnosis is provided by an automated segmentation method of infection areas in the lungs. As an outcome, automatic image segmentation is in high demand as a clinical decision aid tool. To detect COVID-19, Computed Tomography images might be employed instead of the time-consuming RT-PCR assay. In this research, a unique technique is provided for segmenting infection areas in the lungs using CT scan images from COVID-19 patients. “Ground Glass Opacity (GGO)” regions were detected using Novel Adaptive Histogram Binning Based Lesion Segmentation (NAHBLS) method. Many metrics were also employed to evaluate the proposed method, including “Sorensen–Dice similarity”, “Sensitivity”, “Specificity”, “Precision”, and “Accuracy” measures. Experiments have shown that the proposed method can effectively separate the lung infections with good accuracy. The results show that the proposed Novel Adaptive Histogram Binning Based Lesion Segmentation based on automatic approach is effective at segmenting the lesion region of the image and calculated the Infection Rate (IR) over the lung region in Computed Tomography scan.","PeriodicalId":13656,"journal":{"name":"Int.

Therefore, there should be ICT provision in underserved communities to bridge digital literacy and contribute to human and indigenous knowledge development. This paper aims to investigate how ICT access can impact youth employability in underserved townships. The quantitative method was used for the data collection process, using a structured questionnaire to draft both close-ended and open-ended questions. These were drafted into Google forms and distributed on social media platforms. While the sustainable livelihood theory was used to guide the study. Results derived from this study depict the inherent environmental factors that hinder youth access to ICTs. This study recommends policymakers can implement measures to provide sufficient ICT development initiatives to support youths living in underserved communities.","PeriodicalId":13656,"journal":{"name":"Int.

This study is motivated by the continuous challenges that are encountered by many African countries, either in the development or implementation or both, of the e-governance solution. The interpretivist approach was employed, and qualitative data were gathered using the semi-structured interview technique. Activity theory was used as a lens to guide the analysis of the data, from which six factors were found to influence the implementation of e-governance in the country. The factors are know-how; requirements of both technical and non-technical components; political-will, which draws on power to make decisions; heterogeneity; a repertoire of actors-power relationship; and governance, which includes standards, policies, and principles. The empiricism nature of the study boosts knowledgeability of the challenges that hinder implementation of the solution, which in-turn affect service delivery.","PeriodicalId":13656,"journal":{"name":"Int.

This is achieved by gathering knowledge and data on the protection of cybersecurity and analyzing the different tools and methods that terrorist organizations use to implement their cybercrimes. The goal is to find ways to overcome the various challenges that terrorists pose to regional (Arab-wide) and international cybersecurity systems to find mechanisms and solutions to deal with this phenomenon effectively and to reduce its increasing risks to people and the security, stability, and economies of nations. The most significant conclusion that was reached is the need to continue international efforts to strengthen the fight against cyberterrorism and to establish a binding legal treaty in this regard so as to prevent further harm to the safety of the international community.","PeriodicalId":13656,"journal":{"name":"Int.

It further sheds light on priorities for preparedness measures that need to be taken to ensure continuity during these adversities. Exploratory research was conducted in the form of focussed interviews with 20 senior management industry professionals, and these were analyzed using N-Vivo, and four important determinants of business continuity were identified based on which a research model was conceptualized using business continuity as dependent variable and others as independent variables. The model was further tested using quantitative research. For this purpose, a questionnaire was prepared, and a total of 200 responses were collected representing 26 sectors. These responses were analyzed using factor and variance analysis, and a multiple regression analysis was performed to test the role of these variables on business continuity. It was further concluded that the factors that ensure business continuity differ according to the industry in which the business is operating.","PeriodicalId":13656,"journal":{"name":"Int. J.
