AI 지능을 이용하여 개인별 학습지를 생성하여 학習 효율性和 대상성 을 향상시킵니다. Note: There seems to be a mix of Chinese and English in the original sentence. I've translated it to Korean maintaining the meaning as closely as possible. However, "효율性和 대상성" might not be the exact terms used in Korean for "效率與針對性". If you could provide the exact terms, I can adjust the translation accordingly.
