The fifth-generation (5G) cellular infrastructure is expected to bring about the widespread use of connected vehicles. This technological progress marks the beginning of a new era in vehicular networks, which includes a range of different types and services of self-driving cars and the smooth sharing of information between vehicles. Connected vehicles have also been announced as a main use case of the sixth-generation (6G) cellular, with ultimate requirements beyond the 5G (B5G) and 6G eras. These networks require full coverage, extremely high reliability and availability, very low latency, and significant system adaptability. The significant specifications set for vehicular networks pose considerable design and development challenges. The goals of establishing a latency of 1 millisecond, effectively handling large amounts of data traffic, and facilitating high-speed mobility are of utmost importance. To address these difficulties and meet the demands of upcoming networks, e.g., 6G, it is necessary to improve the performance of vehicle networks by incorporating innovative technology into existing network structures. This work presents significant enhancements to vehicular networks to fulfill the demanding specifications by utilizing state-of-the-art technologies, including distributed edge computing, e.g., mobile edge computing (MEC) and fog computing, software-defined networking (SDN), and microservice. The work provides a novel vehicular network structure based on micro-services architecture that meets the requirements of 6G networks. The required offloading scheme is introduced, and a handover algorithm is presented to provide seamless communication over the network. Moreover, a migration scheme for migrating data between edge servers was developed. The work was evaluated in terms of latency, availability, and reliability. The results outperformed existing traditional approaches, demonstrating the potential of our approach to meet the demanding requirements of next-generation vehicular networks. [ABSTRACT FROM AUTHOR]

Background Prolongation of the QT interval is associated with lethal arrhythmias. Early identification of QT/QTc prolongation followed by appropriate clinical interventions can avert this potentially lethal arrhythmia. Aim of the study To assess the association between QTc-interval prolongation and increased risk of cardiac arrhythmia in critically ill patients. Research design A descriptive correlational research design was utilized. Setting The study was conducted in the Critical Care Department, Al-Manial University Hospital, Cairo University. Patients and methods A purposive sample consisted of 270 adult patients. Tools of data collection An assessment sheet consists of two parts: part I: patients’ demographic and medical data, and part II: QT-interval monitoring sheet. Results The mean age of the study sample was 60.16±16.05, and 53.3% were males. Also, there was a statistically significant difference in patients’ QTc mean through five observations (f=19.086; P≤0.001). Moreover, there was no significant statistical difference in patients’ QT average means through five observations by their laboratory investigations and their diagnosis (P>0.05, P=0.133), respectively. Conclusion The highest prolongation of QTc was in torsade de pointes, and the lowest QTc prolongation was in atrial fibrillation. Recommendation Nursing assessment of critically ill patients in association with QTc calculation for early detection of lethal cardiac arrhythmia. [ABSTRACT FROM AUTHOR]

Many factors are currently pushing the hospitality sector to be more environmentally friendly. Moreover, hotel management is increasingly aware of its environmental impact, and it is gradually taking positive steps and green initiatives such as conserving water, energy-saving and solid waste reduction." Many hotels have already applied for some green plans. Besides, customers began to prefer green rather than regular hotels during their stay. This research aims to determine what influences the intention of hotel guests to participate in green activities. Results have also shown that green hotel policies and practices are well accepted by tourists, such as energysaving light bulbs in guest rooms, recycling bins in rooms and lobbies, as well as green certifications. Many guests agreed to the green initiatives proposed in the study. They preferred to stay and participate in greenbased practices and programs in hotels unless this could increase accommodation costs. The result also provides hoteliers with how these attributes can attract holidaymakers who care about the environment. These programs require to be monitored continuously with the growth in the greening of hotels. Finally, hotel establishments must pay attention and start implementing some of these green initiatives because they are inexpensive and help protect our environment. [ABSTRACT FROM AUTHOR]
