This study conducted a team-based CPR simulation with 32 fourth-year emergency rescue students to determine the effectiveness of training feedback using body cameras used at emergency rescue sites, and measured awareness, training feedback effectiveness, and satisfactio+n before and after body camera feedback. , preferences and difficulties in using body camera devices were identified. Data analysis was performed using SPSS 27.0 program, including descriptive statistics, frequency analysis, paried t-test, and Wilcoxon signed rank test. As a result of the study, the perception of body camera use showed a positive change from 3.73±0.62 points to 4.45±0.54 points, and a positive satisfaction level of 3.98±0.51 was shown (p<.001). Additionally, there was a significant increase in self-check accuracy and performance score after body camera feedback (p<.001). Therefore, during team-based simulation resuscitation training, positive feedback effects in improving self-inspection ability and performance can be achieved by watching body camera videos and using self-checklists without direct feedback from the instructor.

레피어 직기는 1,000rpm 이상의 워터제트와 에어제트 직기의 생산성에 미치지는 못하지만 제직 범위가 넓고 다양한 색사 사용이 가능하다는 장점으로 인해 고급직물을 생산하기 위해 오늘날에도 폭넓게 사용되고 있다. 현재는 외국 선진국뿐만 아니라 국내에서도 레피어직기는 제트직기와 더불어 주력개발기종 중의 하나이다. 근래 레피어직기의 개발방향은 고속화에 주력하고 있다. 레피어를 고속화하기 위한 시도는 위입구동부, 바디침기구, 개구부, 송출부 및 권취부 등 전반적으로 검토되어야 하지만 본 연구에서는 바디침기구의 고속화를 위해 바디침기구의 구동원이 되는 구동캠의 성능향상에 목적을 두고 수행되었다.

When restoring with a dental digital system for implant-supported prosthesis, a double digital scanning technique is required: an intraoral scan of the three-dimensional implant location and intraoral scan after placement of temporary denture or provisional prosthesis. During the intraoral scan, the use of scan body as a stable landmark can improve the accuracy of digital impression and simplify laboratory process. In this case, a full-digital system was used to plan and fabricate a custom abutment, provisional prosthesis, and definitive prosthesis. After implant placement, the scan area of the intraoral scan body connected with implant and the intraoral scan body marked on the inside of temporary denture were superimposed. Out of the superimposed files, a custom abutment and provisional prosthesis were fabricated which match the vertical dimension of temporary denture, and definitive prosthesis was fabricated based on provisional prosthesis. We report this case because result has been functionally and esthetically satisfactory by using vertical dimension and central relation set during the fabrication of temporary denture to the definitive prosthesis.
