Thank you for viewing. This is a listing for "Byoki ga Mieru Vol. 15 Pediatrics." I purchased it and stored it after reading it through once. The biggest feature, the **bag containing the "QR code (bonus app version serial code)" is unopened and unused.** 【Recommended for】 • Medical students and nursing students: For clinical practice and national exam preparation. The illustrations are abundant, so understanding is overwhelmingly faster than with textbooks that are just text. • Young doctors and residents: When you want to immediately check the overall picture of a disease in the field. • Nurses and medical staff assigned to pediatrics: For those who want to visually understand the mechanisms of complex pediatric diseases. • Those who want to study on their smartphones: Since the serial code is unused, you can register for the app version without additional charges and study without carrying heavy books.
