In the actual context of social distancing due to the Coronavirus, many hospitality facilities face an economic crisis. Tourists are very concerned and think twice before choosing to accommodate in a hotel. In order to limit human contact, many studies have been developed with the aim to find the best options for front desk services and tourist access control. Other issues that had to be taken care of were security and energy efficiency. This paper proposes a study of different hotel management facilities that should respond to the actual needs of both the hoteliers and the tourists, in order to ensure a safer and comfortable staying.

Context: Nowadays, developing computer skills is important for a student's success. Objective: Smart classrooms bring new experiences for both students and teachers not only in this current context, by increasing safety, data availability, teaching and learning optimized processes, and much more. Method: For improving the transmit and receive process (TX and RX) performances of the educational experience, we propose a system based on a Learning Management System (LMS) and the Internet of Things (IoT). Results: The results of this concept can be perceived at a theoretical level for now. LMS and IoT offer high tech solutions for sustainable and smart classrooms. The immediate result is the improvement of everyday activities and learning methods. Conclusion: The aim of this paper is to describe the efficiency of the LMS and IoT infrastructure in restructuring the traditional learning methods.

The actual situation facing mankind due to the new Coronavirus is pushing researchers to develop new technologies that involve physical distancing for people, in many domains. But life goes on, and although some activities can be carried out online, there are some domains that require human presence. For example, analysis of the environment, evaluating exposure to different toxicants to different ecosystems are some of the activities in the environment sector that need to be carried out involving human presence. This is why this paper will propose a system that limits human contact during hotel stays for scientists, researchers, or tourists.

Context: The education sector is the root of our society. Living in a fast changing environment, we need to keep pace by implementing new technologies and techniques. A widespread solution is the Internet of Things together with Cloud computing technologies. Both technologies offer sustainable solutions for improving the efficiency of learning and teaching. Thus, these IT solutions become the main aspect of our society by interconnecting heterogeneous devices and technologies in different aspects of life. Objective: This paper focuses on the Internet of Things' major technologies and applications with an orientation in the education sector. This overview can help scholars and academia to adopt and participate in the endeavor to streamline the receive-transmit process of education. Method: A systematic literature review was performed considering the main scientific databases. The number of the research paper was narrowed after the exclusion criteria were applied. Results: This paper underlines the importance of adopting both IoT and Cloud computing in teaching and learning activities. The evidence on the diversity of both IoT and Cloud computing applications are underline
