이종필,Lee, Jong Phil 한국국토정보공사 공간정보연구원 2021 지적과 국토정보 Vol.51 No.1

최근 초경량무인비행장치(UAV)의 활용과 영상처리 기술 발달로 인해 정사영상과 수치모형 등을 활용한 응용 분야가 다양해지고 있다. 특히 토지측량분야에서도 이러한 결과물을 활용하여 위험지역분석과 같은 공간정보 활용이 활발해지고 있다. 본 연구에서는 UAV 고해상도 영상을 활용하여 고저차가 심한 경사지에서 정사영상의 위치정확도와 수치표면모델의 수직위치 정확도를 분석하고자 하였다. 연구 결과 대상지역 전역에 고르게 분포한 지상기준점(GCP)인 경우 2차원 정사영상에서 평면위치 오차는 크지 않았다. DSM의 수직위치의 경우 GCP의 선점위치를 점 간 고도차를 약 10m, 20m, 30m, 40m로 구분하여 전체를 포괄하는 각 8점의 GCP와 검사점을 대상으로 분석한 결과 비행코스별 고르게 분포되고 GCP 점 간 높이차가 30m일 경우(RMSEZ=0.07m) 가장 높은 정확도를 보였다. 본 연구지역과 유사한 대상지역을 UAV를 활용하여 수치모형을 제작할 경우 GCP 위치선정과 수직위치 정확도 향상에 도움이 될 수 있기를 기대한다. Recently, Unmanned Aerial Vehicle utilization and image processing technology for remote sensing have diversified remarkably with Orthophoto and Digital Surface Model. In particular, It uses more application fields such as spatial information analysis and hazardous areas as well as land surveying. This study analyses the accuracy of the coordinate on Orthophoto and DSM height on slope area with high and low differences by using UAV images. As the result of this study, in the case of GCP on 2D orthophoto, the location error was not produced significantly. The vertical position of the DSM showed the highest accuracy when the height difference between GCPs is under 30m(RMSEZ=0.07m). The location of the GCPs was divided into approximately 10m, 20m, 30m, and 40m with analysis for each of the eight points of GCP and inspection points in general. This study expects that producing both horizontal accuracy of Orthophoto and vertical accuracy of DSM using UAV on the sloped area which similar to this research area will help in spatial information fields.

지난 20년 동안 우리나라 국제여객항 카페리의 여객과 화물 운송 실적은 각각 연평균 8.6%의 증가율을 기록하였다. 하지만 항로의 발전과 항차의 양적 증대에 비해 국제여객항의 비효율적인 관리체계에 대한 개선 요구가 끊임없이 제기되어 왔다. 본 논문은 중요도-성취도(IPA) 기법을 응용·적용하여 우리나라의 대표 국제여객항인 인천항을 중심으로 최근 국제여객선 수급상황 변화와 정부·민간 등 이용 주체의 개선 요구를 반영한 여객터미널 관리체계 전반의 개선사항과 추진 방안을 제시하였다. IPA 분석결과, 인천항 국제여객터미널의 ‘운영’ 부문에서는 세관인력의 확대 및 상시통관 시스템 시행, ‘시설’에서는 연락교-선석 간 완충시설 설치 및 카페리 화물 전용 배후단지 마련, ‘제도’의 경우 비용부담 주체의 명확한 기준 설정 및 터미널 이용 관련 비용의 인상폭 제한 등이 관리체계 개선에 가장 필요한 항목으로 나타났다. 본 연구의 결과는 국제여객항의 효율적인 관리체계를 위해 운영, 시설 및 제도 등 다각적 차원에서 이해관계자의 의견을 반영한 정부의 정책 접근과 투자의 필요성을 시사한다. Over the past 20 years, Korea’s number of international passengers and freight transportation records has increased by 8.6% per year, respectively. However, despite the development of sea lanes and increased voyages, there have been constant calls for improving the inefficient management of international passenger ports. Hence, this paper presents improvements and further directions for international passenger port management. Focusing on the Incheon International passenger port as a representative case study, the main results show that the most important, urgent, possible measures for improving the port management include (i) the expansion of customs personnel and implementation of a 24-hours customs clearance system in operation, (ii) installation of buffer facilities between the ferry and ferry cargo and establishment of hinterland specialized in car ferry freight in a facility, and (iii) clear standards for cost-bearing subjects and limitation of high cost related to terminal use in institution. These results imply the need for government policy access and investment reflecting stakeholder opinions at various levels, such as operation, facilities, institution, and so forth, for efficient management of international passenger ports.

Objective : Adrenal medullary chromaffin cells are known to release analgesic substances such as opioides and catecholamines. Transplantation of them is a novel method that challenges current approaches in treating chronic pain. The transplantation of xenogeneic chromaffin cells into the central nervous system(CNS) supply antinociception in animals. In this study, we investigated the analgesic effects of rat adrenal medullary chromaffin cells transplanted into the CNS of the mouse. To study the antinociceptive efficacy of transplanted chromaffin cells, the survival of rat adrenal medullary chromaffin cells transplanted into the CNS of mouse was determined. Methods : The adrenal medullary chromaffin cells isolated from rat were transplanted into the striatum of mouse. These cells were confirmed of the release of Met-enkephalin and Leu-enkephalin by HPLC, and immunoblots for tyrosine hydroxylase(TH). Two weeks after transplantation, we performed immunohistochemistry for TH to determine the survival of implanted cells and assessed pain sensitivity at the same time. Results : The isolated rat adrenal medullary chromaffin cells were positive for anti-TH antibody and released Met-enkephalin and Leu-enkephalin more than rat endothelial cells. Transplanted rat chromaffin cells were stained with anti-TH antibody in striatum of mouse after 2 weeks. Pain sensitivity was reduced on the chromaffin cell-transplanted mouse compared to endothelial cell-transplanted mouse by the hot plate test. Conclusion : These results suggest that the rat chromaffin cells were suitably transplanted into the CNS of mouse. This approach could be used as a therapy for reducing of chronic pain induced by cancer or neuronal injury.
