Legal Improvement Measures to Prevent Defective Real Estate Registration - Analysis of the importance of improvement factors using AHP -

Jeong-Yun Ahn, Jaewoo Lee

형식적 심사주의와 절차적 행정에 치우쳐 있는 현행 등기제도는 국민 재산권 보호와 거래 안전성 확보라는 기존 목적을 충분히 달성하지 못하고 있는 것이 현실이다. 이에 본 연구는 우리나라 부동산등기제도의 구조적 문제를 해결하고 현실적 대안을 도출하고자 전문가와 실무자 인식에 기반하여 제도 개선 대안의 중요도를 분석하고 …

Synergistic Multi-UAV Path and Surveillance Planning Using APF-Enhanced PPO

HyeonJun Lee, Jun Hyeok Ji, Bongkyo Moon, Aye Aye Maw et autres

In this paper, a novel approach to multi-UAV mission planning is proposed, combining Proximal Policy Optimization (PPO) with Artificial Potential Fields (APF). The methodology efficiently addresses complex objectives such as collision avoidance in three-dimensional environments, evasion of detected threats, and surveillance of …
