Of the material assignments we evaluated, polytetrafluoroethylene (PTFE) showed the best overall agreement with measurement. Calculated and measured doses agree within 3.5% for a 340-degree arc technique (which averages transmission and scatter effects) with the Acuros XB algorithm and PTFE as the assigned material. To confirm that PTFE is a reasonable substitute for kyphoplasty cement, we performed measurements in a slab phantom using rectangular inserts of cement and PTFE, showing average agreement of all photon modes within 2%. Based on these findings, we conclude that the PTFE material assignment provides acceptable dose calculation accuracy for the AAA and Acuros XB photon algorithms in the Eclipse TPS. We recommend that the cement be delineated as a structure and assigned the PTFE material for accurate dose calculation. "Message order" and "active participation" could be effective as risk communication methods. "Anticipated regret" (AR) has also been recognized as affecting risk perception and vaccine uptake in vaccination risk communication. We aimed to evaluate the effects of message order and active participation and the interactions between these two interventions on AR for vaccination. We conducted a 2 (message order positive-negative or negative-positive) × 2 (message calendar with or without planning) factorial design study among 81 study participants. The effects of message order and active participation of mothers, using a message calendar, were evaluated on mothers' decision-making regarding vaccination with Haemophilus influenzae type b vaccine and pneumococcal conjugate vaccine for their children. Participants completed questionnaires to evaluate the AR of infection if unvaccinated (anticipated regret of inaction) and of side effects if vaccinated (anticipated regret of actio
