This study explored the mechanism by which stars and fans build a global fandom community based on social connectivity of social media based on BTS' official Twitter and in-depth interviews with Chinese, American, and Korean fans. Stars and fans use the connectivity of social media to build a pseudo-private relationship that crosses public and private affairs. Even though they won the award, BTS "congratulates" the fan club, ARMY, and organizes a dialogue method so that each fan becomes the subject. From a fan's point of view, it comes to be seen as a personal message to them, which is not just applied to the text composition method. On days when there is no public message such as official activities or anniversaries, a device to communicate without missing a day has been prepared by raising private messages or previous memories. It was found that the sense of constant connection strengthens fans' sense of community toward each other.

This paper investigates using small UAVs as communications relay nodes for expanding communications links and improving communications quality, primarily for a fleet of ground or navy vessels. An airborne relay in ground/maritime space can effectively connect to units operating over the horizon, beyond normal communication range, or under limited satellite communication environment. Even if the equipment development is mature for communications relay, where to locate UAVs for efficient relay is still a pending question. With this background, this paper will develop high-level deployment algorithms to optimize the location of UAVs for improving the connectivity of a wireless network among a fleet of ground or navy vessels.
