The development of smart devices has brought about significant changes in daily life and one of the most significant changes is the virtual reality zone. Virtual reality is a technology that creates the illusion that a 3D high-resolution image has already been created using a display device just like it does in itself. Unrealized subjects are forced to rely on audiovisual materials, resulting in a decline in the concentration of practices and the quality of classes. It used virtual reality to develop effective teaching materials for radiology students. In order to produce a video clip bridge using virtual reality, a radiology clinic was selected to conduct two exposures from July to September 2017. The video was produced taking into account the radiology and work flow chart and filming was carried out in two separate locations : in the computerized tomography unit and in the LINAC room. Prior to filming the scenario and the filming route were checked in advance to facilitate editing of the video. Modeling and mapping was performed in a PC environment using the Window XP operating system. Using two leading virtual reality camera Gopro Hero, CC pixels were produced using a 4K UHD, Adobe, followed by an 8 megapixel resolution of $3,840{\times}2,160/4,096{\times}2,160$. Total regeneration time was performed in about 5 minutes during the production of using virtual reality to prevent vomiting and dizziness. Currently developed virtual reality radiation and educational contents are being used to secure the market and extend the promotion process to be used by various institutions. The researchers will investigate the satisfaction level of radiation and educational contents using virtual reality and carry out supplementary tasks depending on the results.

Background: Cardiac injuries are the most commonly overlooked injuries in patients who die from trauma. Patients who survive blunt cardiac rupture or penetrating injuries are rare and the incidence is not well defined. Many patients require urgent or emergency operations and operative mortality is very high. Material and Method: A retrospective review of 26 patients with cardiac injuries due to thoracic trauma undergoing emergency thoracotomy from January 1997 to December 2005. Result: There were 17 male and 9 female patients, with a mean age of $45.3{\pm}16.2\;(range:\;17{\sim}80)$. Thirteen patients (50%) were injured in motor vehicle accidents, and five patients (19%) in motorcycle accidents. Six patients (23%) were injured by knives, and two patients (8%) were injured by falling. Anatomic injuries included right atrium (12 [46%]), left atrium (1 [4%]), right ventricle (5 [19%]), left ventricle (5 [19%]), and cardiac chambers (2 [7%]). Diagnosis was made by computer tomography in 12 patients and sonography in 14 patients. The average times from admission to operating room was $89.2{\pm}86.7\;min\;(range:\;10{\sim}335)$. The average time for diagnosis was $51.3{\pm}13.6\;min\;(range:\;5{\sim}280)$. The mean Revised Trauma Score (RTS) was $6.7{\pm}0.8$, and the Glasgow Coma Scale (GCS), was $12.8{\pm}2.8$. The overall mortality rate was 12% (3 out of 26 patients). Conclusion: The mortality rate from cardiac injury is very high. The survival rate can be increased only by a high index of suspicion, aggressive expeditious diagnostic evaluation, and prompt appropriate surgical management.
