ABSTRACT
This study examines how perceived organizational support (POS) can be leveraged to provide employees with guided responses to disruptive events. Specifically, this study addresses a previously overlooked yet practically relevant aspect of POS—its communicative role in managing employees' feelings of job insecurity. Drawing on the social identity perspective and research on individuals' psychological states of uncertainty, we argue that POS can have both direct and indirect influences on the sense of job insecurity in times of external threats. With this in mind, we used COVID-19 and resulting lockdowns in China as specific context examples of a disruptive event to administer a two-wave lagged survey measuring POS, perceived control, lockdown loneliness, and job insecurity. Theoretical arguments are put forward regarding organizational support for fostering individuals' social identity and emotional well-being under deeply disruptive work situations. Overall, this study offers insights into how managers may develop risk management and organizationally adaptive practices. © 2023, Springer Nature Limited.

Mobile communication technology is an important information science and technology. With the development and wide application of mobile communication technology, the security of mobile communication has become an important research field, and its security connotation is constantly enriched. First of all, this paper introduces the current situation of people’s life safety and the development of 5G communication technology in the face of COVID-19. Based on this situation, a positioning method is proposed and a method of constructing the association graph between mobile communication devices is designed. A health and safety monitoring system based on mobile communication positioning technology is designed. This paper applies mobile communication positioning technology to health and safety monitoring, and expands the security technology scope of mobile communication technology. © 2022, Springer Nature Singapore Pte Ltd.

ABSTRACT
Coronavirus disease 2019 (COVID-19) has been confirmed to transmit by contact and respiratory droplets, and possibly by aerosols. Medical staff of oral and maxillofacial surgery departments need close contact with head and face of patients during the diagnosis and treatment, and aerosols may be generated during the operation. The risk of infection exposure is high, and the ward management is facing severe challenges. During the COVID-19 epidemic, the diagnosis and treatment in oral and maxillofacial surgery wards should be carried out reasonably after comprehensive assessment of patient condition. We put forward relevant prevention and control measures during the epidemic from the aspects of patient treatment, ward infection prevention and control, supply management, emergency plan, and training of medical staff, so as to provide references for prevention and control of the epidemic in oral and maxillofacial surgery wards.
