Assisting students with autism to cooperate with their peers to perform computer mouse collaborative pointing operation on a single display simultaneously

The purpose of this study was to provide students with autism spectrum disorder (ASD) the chance to cooperate with their peers to perform computer mouse collaborative pointing operation. In this study, we adopted the Single Display Groupware (SDG) concept to develop the Multiple Cursor Collaborative Operating Program (MCCOP) software, which allows multiple users to operate a single computer simultaneously without interfering with each other. With the implementation of MCCOP software, users control their own cursors to perform a function in their respective cursor moving areas on a single display. A collaborative pointing test software (CPTS) program was designed in this experiment to evaluate participants’ collaborative pointing performance. This study adopted an ABAB design, and the experimental results show that all participants significantly increased their collaborative pointing performance during the intervention phase, compared to the baseline phase. Practical and developmental implications of the findings are discussed.

Postoperative convalescence after inguinal hernia surgery: Prospective randomized multicenter study of laparoscopic versus Shouldice inguinal hernia repair in 1042 patients

Interest in inguinal hernia surgery has increased significantly with the introduction of new operating techniques during the past decade. This multicenter study compared short-term results in patients treated by the laparoscopic transabdominal preperitoneal patch technique (TAPP; n=518) and the Shouldice technique (n=524). We evaluated demographics, operative data, complications, hospital stay, postoperative pain, use of analgesics, functional status, sick leave, and complaints up to 3 months postoperatively. The median operating time was shorter in the Shouldice group (55 vs. 65 min), but there were no significant differences in complication rates, and major complications were rare. The hospital stay was 1 day or less in over 98% of cases in both groups, but more operations were performed on outpatient basis in the Shouldice group. In the TAPP group postoperative pain and analgesic consumption were less, postoperative functional status was better, and sick leave was shorter (10 vs. 14 days). These results show that the two methods are equally safe and have few major complications. The TAPP operation is associated with less postoperative pain, better postoperative functional status, and shorter sick leave, but at the price of a longer operating time. Electronic Publication
