최근 해양쓰레기는 환경적 문제뿐만 아니라 해양 생물부터 인간의 건강까지 막대한 해를 끼친다. 또한, 해양 생물의 다양성을 보전하기 위한 해양보호구역에도 많은 양의 해양쓰레기의 피해가 발견되지만 사람에 의한 직접 접근 및 수거는 쉽지 않다. 이를 해결하기 위해 드론 기술을 접목해 해양쓰레기 파악 및 수거 다양한 연구가 진행되고 있다. 이 논문에서는 해양보호구역의 해양쓰레기 수거 체계를 위하여 드론 기술을 접목하여 드론 영상 수집 및 저장 시스템을 제안한다. 해양보호구역과 드론 비행 가능 구역을 비교하여 비행 장소를 선정하고 드론 조종 프로그램을 통해 해양쓰레기 영상을 수집 및 저장하는 시스템을 설계한다. Recently, marine litter not only causes environmental problems, but also causes enormous harm from marine life to human health. In addition, a large amount of marine litter damage has been found in marine protected areas where preserve the diversity of marine organisms, but it is not easy to direct access and collection by humans. To solve this problem, various studies are underway to identify and collect marine litter by incorporating drone technology. In this paper, we propose a drone image collection and storage system by incorporating drone technology for a marine litter collection system in marine protected areas. It compares the marine protected area and the area where drones can fly, selects a flight location, and designs a system that collects and stores marine litter images through a drone control program.

Objectives: Although vaccination rates have increased, problems still remain in the storage and handling of vaccines. This study focused on inspecting actual vaccine storage status and awareness, and comparing them before and after education was provided. Methods: In the primary inspection, a status survey checklist was completed by visual inspection. A questionnaire on the awareness of proper vaccine storage and handling was also administered to vaccine administrators in private medical institutions in 4 regions in Gyeongsangbuk-province. One-on-one education was then carried out, and our self-produced manual on safe vaccine storage and management methods was provided. In the secondary inspection, the investigators visited the same medical institutions and used the same questionnaire and checklist used during the primary inspection. The results before and after education were compared, by treating each appropriate answer as 1 point. Results: The average checklists score was 9.74 (out of 15 points), which increased significantly after education was provided (by 0.84, p<0.001). The participants demonstrated improved practices in recording storage temperatures (p=0.016), storing vaccines in the center of the refrigerator (p=0.004), storing vaccines with other medication and nonmedical items (p=0.031) after education. The average score calculated from the questionnaires was 10.48 (out of 14points), which increased after education (by 1.03, p<0.001). Conclusions: This study suggests that vaccine storage practices and awareness are inadequate, but can be partially improved by providing relevant education. Repetitive education and policy-making are required to store vaccines safely because one-off education and unenforced guidelines offer limited efficacy.

Despite the high commercial value of the pine mushroom (Tricholoma matsutake) around the world, its production still depends upon natural harvesting. In recent years, mushroom researchers in Korea and Japan have been successful in artificially cultivating T. matsutake by producing single mushroom through matsutake-infected pine seedlings. In this study, we determined the minimum seedling height required for the survival of matsutake mycelia in the infected pine seedlings in the field. The survival rate of matsutake mycelia in the matsutakeinfected pine seedlings was 50% (14) in two years and 71% (10) in one year after their transplantation. The average height at time of transplantation of the matsutake-infected pine seedlings that bore surviving mycelia after transplantation was 25 cm (minimum 12 cm to maximum 40 cm). In conclusion, the matsutake mycelium of matsutake-infected pine seedlings was able to survive in field conditions if the height of the seedling at the time of T. matsutake infection was at least 12 cm. These results suggest that the height of the host plants used in conventional matsutake-infected pine seedling production should be greatly reduced to improve the matsutake cultivation. Therefore, standardization of the seedling height for artificial cultivation of pine mushrooms by the matsutake-infected pine seedling method is suggested.
