Item Restricted Improvements of Technical Blockchain to Combat Ransomware Attacks in Healthcare(Newcastle University, 2024) Albalawi, Sarah; Mace, JohnIn the face of increasing cybersecurity threats, ransomware attacks have become a significant risk to critical sectors such as healthcare. As medical healthcare systems increasingly rely on electronic health records, they face heightened vulnerabilities that can compromise patient data and disrupt essential medical services. Ransomware attacks can encrypt and render critical medical records inaccessible, jeopardising patient care. This research aims to develop and evaluate a blockchain-based solution designed to secure medical healthcare records against ransomware, enhancing data integrity, availability, and security in healthcare systems. By leveraging blockchain technology, specifically by using smart contracts and decentralised applications on the Ethereum platform, the proposed solution creates a decentralised, immutable medical record management system. The system's robustness is demonstrated through a Python-based ransomware simulation, which compares locally stored medical data with data managed via blockchain. The findings show that the blockchain-based approach and smart contracts maintain data integrity and availability during ransomware attacks, preventing unauthorised access and ensuring continuous healthcare operations. These results suggest that adopting blockchain technology in healthcare can significantly mitigate the risks posed by ransomware, reduce operational disruptions, and protect patient data from evolving cyber threats, ultimately providing a scalable and secure solution for enhancing cybersecurity in the healthcare sector.16 0Item Restricted Managing Successful Mega Saport Events(Leeds Beckett University, 2024-05-13) Albalawi, Sarah; Laville, LucyMega events are large-scale occasions that are widely publicised to draw visitors domestically and from abroad (Hall, 2006). With considerable improvements in home viewing content and technology the audience who prefers to stay at home and enjoy first-rate experiences without having to deal with the inconvenience of physically being at the event venue has become a rival to the growing quantity and variety of mega events. This suggests, from the standpoint of event management, that mega-events should be planned to involve the physical audience and provide a memorable, transformative experience that makes them want to come back and find more opportunities for interaction (Bowdin, 2011). Saudi Arabia is a new entrant into the world of mega-events with strong government support and finance from the sovereign wealth fund. Technology's accessibility and ease of use suggest that it is affordable and available to everybody, even to new entrants such as Saudi Arabia. The purpose of this study is to investigate whether providing audiences attending mega events in Saudi Arabia with an enhanced experience may be achieved via the use of digital technologies and engaging tactics. The results, which were obtained through the use of a comprehensive survey instrument distributed to the target audience in Saudi Arabia, indicate that going to a mega-event is motivated by more than just a keen interest in the topic, sport, or artist; it's also a way to try something new and get away from social and personal pressures. The results of this study indicated that while both the hard and soft elements of the physical environment are significant, they were not equally so. According to the survey, comfortable furnishings and good visibility are important for the hard physical environment, while convenient scheduling, plenty of clear signage, good service, the availability of event staff to help with problems, and reasonably priced, high-quality food and beverages are important for the soft aspects. The study concludes that safety and security are the most crucial factors for any mega-event. According to this research, when a mega-event is presented in an immersive and interesting way, people have an extraordinarily positive experience. Furthermore, this study discovers that positive attendee experiences result in more positive word-of-mouth. Attendee satisfaction increases the likelihood that they will tell their network about the mega event, which will contribute to its continued success. The study's findings indicate that Saudi Arabia's mega-events have been effective in providing captivating and immersive experiences.18 0Item Restricted The Reality and Obstacles of Teachers' Practicing of Methods of Encouraging Creative Thinking Among Gifted Students in Kingdom of Saudi Arabia(Saudi Digital Library, 2023-02-05) Albalawi, Sarah; Algarrah, Abdeinasser; Alabbasi, AhmedThe current study aims to reveal the level of practice of teachers of gifted students in the Tabuk and Hail regions of methods of encouraging creative thinking from the point of view of students, in addition to identifying the obstacles to creative thinking from the point of view of teachers. The study population consisted of all student teachers in addition to all gifted students in my city Hail and Tabuk in the Kingdom of Saudi Arabia. The study followed the analytical descriptive approach by designing two questionnaires as tools to collect data from the study sample consisting of (150) teachers and (400) students. The SPSS program was also used for statistical analysis, which included arithmetic means and multiple analysis of variance. The study concluded that the means of the practice level of teachers of gifted students in the Tabuk region for methods of encouraging creative thinking from the point of view of the students as a whole is (3.83). The means of the level of obstacles to creative thinking from the point of view of teachers as a whole was (3.04), the results indicated that there were statistically significant differences between the means of students' responses about the level of practice of teachers of gifted students in the Tabuk region for methods of encouraging creative thinking due to the school stage variable in favor of medium stage in all fields and the total score. The results also indicated that there were statistically significant differences in the field of creative thinking obstacles related to the curriculum between teachers whose experience ranged between (5 years - less than 10 years) ,(less than 5 years) and those with more than 10 years of experience, their experience ranges between (less than 5 years) and between (5 years - less than 10 years), decision-making and taking in accordance with the requirements of the times and students' tendencies and desires.41 0
