Purpose: To objectively define the degree of cupping, the authors extracted 3-dimensional slope surface maps from Cirrus HDTM-OCT data and assessed their differentiating characteristics between normal subjects and glaucomatous patients. Methods: One eye from each of 40 normal subjects and 1 eye from each of 39 patients with glaucoma were examined using automated visual field perimetry and Cirrus HDTM-OCT. The Optic Disc Cube 200 × 200 protocol was performed. The individual OCT data were reconstructed as the 3-dimensional surface maps of the optic disc cup and the slope of each contour was calculated using custom-developed software. Several disc cup slope parameters were derived. The parameters measuring the internal features of the optic disc cup were calculated and compared between groups. Results: Sum of cup slope, sum of thresholded cup slope, and sum of thresholded cup slope / thresholded cup area parameters were differentiating factors between the normal and glaucoma groups (p < 0.05). The area under the receiver operating characteristic curve (AUROC) value of the slope parameters ranged from 0.718 to 0.753. The sum of thresholded cup slope / thresholded cup area parameter was well correlated with visual field mean deviation (r = -0.250, p = 0.028). Conclusions: The optic disc cup slope parameter obtained with OCT may be a useful parameter for representing glaucomatous cupping.

1995 년 아리랑위성 1 호 사업 수행 시에는, 아리랑위성 1 호 지상국의 성공적인 구축과 운영준비/운영에 중요성을 두었다. 1 호 사업의 성공 후, 지상국 핵심 기술에 대한 국산화를 확대 추진하였고, 그 과정에서 항우연의 자체 역량의 강화와 함께 자체 수행하는 부문의 확대를 추진하여왔다. 이러한 10 여년의 연구, 개발, 운영과정을 통해, 현재 항우연 지상국의 경우, 국내 유일의 실용급 저궤도/정지궤도 위성관제 능력을 보유하고 있으며, 관제, 수신, 처리분야에서 내부 기술력을 축적하여왔다. 축적된 역량을 바탕으로, 이제는 향후 10 년 후의 수요에 대비하여, 다중위성 시스템으로의 고도화 연구, 관련 기술의 표준화, 제품 및 운용서비스 상용화까지 추진 중에 있다. 본 논문에는 그간 항공우주연구원의 축적된 연구 개발 성과 및 위성 지상국 관련 제공 가능한 분야의 서비스들이 기술되어 있다. During the KOMPSAT-1 satellite program staring in 1995, it was mainly concentrated on the successful deployment and operation of ground system. After the success of KOMPSAT-1 program, the main goal has been shifted to boost its technical competition through the expansion of localization on the core technology in all ground system. As a result of around 10 years effort to enlarge the localization so far, KARI has accumulated both invaluable experience in satellite operation, mission data receiving and processing of both LEO and GEO satellite and engineering capacity through deep involvements in system implementation. Based on the specialized experience and capacity, study on the advanced ground system in multi-missions operation environments, standard on the relevant core technologies, and commercial products and services is in progress to meet the potential needs in next 10 years. This paper describes the R&D capacity achievements by KARI and service items which can be served by KARI
