This study focuses on the development of a Last-Mile delivery service using unmanned vehicles to deliver goods directly to the end consumer utilizing drones to perform autonomous delivery missions and an image-based precision landing algorithm for handoff to a robot in an intermediate facility. As the logistics market continues to grow rapidly, parcel volumes increase exponentially each year. However, due to low delivery fees, the workload of delivery personnel is increasing, resulting in a decrease in the quality of delivery services. To address this issue, the research team conducted a study on a Last-Mile delivery service using unmanned vehicles and conducted research on the necessary technologies for drone-based goods transportation in this paper. The flight scenario begins with the drone carrying the goods from a pickup location to the rooftop of a building where the final delivery destination is located. There is a handoff facility on the rooftop of the building, and a marker on the roof must be accurately landed upon. The mission is complete once the goods are delivered and the drone returns to its original location. The research team developed a mission planning algorithm to perform the above scenario automatically and constructed an algorithm to recognize the marker through a camera sensor and achieve a precision landing. The performance of the developed system has been verified through multiple trial operations within ETRI.

해양수산부와 산업통산자원부가 공동으로 추진하고 있는 자율운항선박 기술개발 프로젝트의 핵심기술은 지능항해시스템, 기관자동화시스템, 성능실증센터 및 실증기술, 운용기술 및 표준화로 나누어지며, 대한민국은 2025년까지 자율운항수준을 대양에서는 IMO Level 3, 연안에서는 IMO Level 2까지 달성하는 것을 목표로 하고 있다. 한편, 삼면이 바다로 둘러싸인 대한민국은 세계물류 이동의 거점임과 동시에 어선 등록 척수가 매년 6만 5년여 척이 넘는 어업이 활성화된 나라이며, 주요 어업 해역인 남해안은 대표적 무역항인 부산항, 광양항 등으로 통하는 항로와 중첩되기 때문에 자율운항선박의 원활한 운항을 위해서는 어업이라는 변수가 반드시 고려되어야 한다. 이 연구에서는 핵심기술 중 지능항해시스템 기술개발과 관련, 어업이 지능항해에 미칠 수 있는 영향을 어구, 어법, 어선으로 분류하여 고찰하였고, 발생 가능한 변수를 줄이기 위한 연구 방향을 제시하였다.

The Korea Post is providing postal, savings, and insurance services to the public. Although it has been automated due to the development of the industry, the risk of industrial accidents is high. Safety and health education should be effectively conducted to reduce industrial accidents. In this study, a survey was conducted for postal service workers. As a result, there was a tendency to prefer instructors with technical experience and professional qualifications, and increasing direct participation training through on-site inspection and audio-visual training and hands-on training were found to be helpful. analyzed. Based on this, an efficient safety and health education plan was presented to improve safety and health awareness, and it can be used as a basic data
