Instant messengers (IM) mediate several types of negative social exchanges that can affect the psychological well-being of their users. Using an instant messenger popular in Taiwan (LINE) as an example, this study examined the relationship between IM communication and well-being. An online survey was conducted and found that negative IM social exchanges in which messages were ignored by their recipients, interfered with other activities, or contained hostility or ridicule were directly related to a global measure of negative social exchange that included face-to-face as well as online interactions. Insensitive IM social exchanges were positively related to loneliness, depression, and fear of missing out (FoMO), and were negatively related to social support.

Interlocking nailing is a common surgical operation to stabilize fractures in long bones. One of the difficult parts of the surgery is how to locate the position and direction of a screw hole on the interlocking nail, which is invisible to the naked eye after insertion of the nail into the medullary canal. Here, we propose a novel two-stage targeting process using two passive magnetic devices to locate the position and direction of the screw hole without radiation for the locking screw procedure. This involves a ring-shape positioning magnet inside the nail to generate a magnetic field for targeting. From the accuracy test results of these two-stage targeting devices, the search region can be identified in less than 20 seconds by the 1st-stage targeting device, while the total targeting time to locate the drilling position and direction takes less than 4 minutes, with 100% successful rate in 50 attempts. The drilling test further combines the two-stage targeting process and drilling process on the swine tibia, and it is shown that a 100% successful rate is achieved in all 10 attempts, where the total time needed is less than 5 minutes.
