The switching of LLC converter becomes hard switching at the time of overload. In this study, we elucidated the mechanism of hard switching and the current path. The reason of hard switching is the commutation of magnetizing current to the secondary side. It is possible to make a judgement whether overload or not from the voltage value at the end of resonance. Voltage value can be obtained from the circuit constants. In this way, it becomes possible to judge the success or failure of soft switching from the circuit constants.

For maintaining resilience of socio-technical systems, it is believed that knowledge sharing among practical ?eld staffs should be a crucial. The purpose of this study, therefore, is to propose a new method to enhance their knowledge sharing effectively. Especially, authors focused on their chats in a refresh room and developed a method to promote their job-related chats in a refresh room by using a large size touch panel display presenting a lot of job-related information. Authors conducted the experiments to examine the effect of developed method. As a result, the expected effect was observed approximately while some possible limitations related to characteristics of job and human relationship among target members were captured. In the conclusion, future works are discussed.
