  • 본격적인 우주기술 활용시대가 전망되는 현재의 시점에서 고해상도 영상취득이 가능한 국토관측위성의 발사가 2021년으로 예정되어 있다. 이에 따라 국토관측위성의 지상국의 핵심설계요소로 영상사용자의 위성영상 활용성과 작업자의 처리효율성 증대가 강조되어 왔다. 이에 대응하여, 국토관측위성의 수집, 처리, 저장, 관리 및 활용을 위한 핵심기술과 국토관측위성 지상국의 운영시스템을 개발하는 국토관측위성 수집 및 활용기술개발 연구사업이 진행되었다. 본 논문에서는 상기 연구개발사업의 성과로 개발된 국토관측위성 활용핵심기술과 지상국 운영시스템 개발결과를 소개한다. 개발된 지상국 운영시스템은 한반도 전역의 GCP(Ground Control Point) chip DB(Database)와 DEM(Digital Elevation Model) DB를 시스템 내에 구축하여 자동화된 방식으로 정밀정사영상을 생성하기 위한 기술 및 시스템을 구현하였다. 나아가 생성된 정밀정사영상을 1:5,000 도엽단위로 분할한 도엽정사영상을 생산하여 향후 분석준비자료 (ARD(Analysis Ready Data)) 체계로 발전할 수 있도록 개발하였다. 또한 정밀정사영상 및 도엽정사영상으로부터 DSM(Digital Surface Model)자료, 변화탐지지도, 객체추출지도 등 다양한 활용산출물이 체계적으로 생산될 수 있도록 활용산출물 생산 SW를 지상국 운영시스템과 연동시킬 수 있게 개발하였다. 본 연구진이 개발한 국토위성정보 활용기술 및 운영시스템은 국내 최초로 한반도 GCP chip DB구축을 통해서 자동화된 정밀정사영상생성 기술을 확보하고 다양한 활용산출물의 생산을 위성지상국 운영시스템에 접목했다는 점에서 의의가 있다고 판단된다. 개발된 국토위성정보 운영시스템은 국토관측위성의 주 활용부처인 국토지리정보원 국토위성정보활용센터에 설치되었으며, 향후 동 센터의 업무에 크게 기여할 것으로 바라보고 있다. 또한, 향후 발사예정인 여러 저궤도 지구관측위성의 지상국 시스템에 대한 기준을 제시할 수 있을 것으로 기대한다.

  • Under the current medical system, a terminal patient and his/her family who are neglected inevitably face various aspects of crises including not only physical, but also psychological, social, economic, spiritual and legal problems. Nurses often look after many terminal patents with these types of complicated problems. Therefore, educating the nurses who will take care of such patents would greatly reduce stress so the patents end could their lives in peace and without losing their dignity. This research is a quasi experimental study of nonequivalent control group. A pretest-posttest design where a basic education program is developed for nurses, who frequently treat terminal patents, to understand the importance of the role of hospice and to apply their understandings to treat terminal lancer patents. A sample of the nurses were taken from those who were working in general wards at two general hospitals in Seoul during October, 2003${\sim}$December 2003. The study was composed of 46 experimental group and 43 control group. A basic hospice education program was developed by taking emphasized and overlapping parts from advanced practice hospice nurses education course, short-term education course, an extensive literature survey and by consulting three professionals as well. With the group of 5 professors with vast experiences in oncolgy, 5 nursing administrator, 3 nursing practitioner, the tentative first version of the program was developed and reviewed. Afterwards, by utilizing person to person interviews with 2 head nurses experienced with terminal patients, 1 nurse in charge of hospice, 1 nurse on the contents of the program, and a person to person rating on the educating medium by a nurse were performed. The final version of a basic education program was developed after the second revision. The hospice basic education program consists of introduction to hospice, hospice and commucation, management of pain for terminal cancer patients, physical management for terminal cancer patients, socio-psycological caring of terminal cancer patients and management of death and separation. Total education time was four hours organized into 50 minutes of instruction and 10 minutes of break. $Powerpoint^{(R)}$ software was used as the education medium. As research tools, "Knowledge on Hospice" was developed by the author after receiving a review from one expert. "Attitude of Hospice Nursing" was revised Kim(2001)'s attitude measuring tool which was based on Wang(1998), Kwon(1989), Park and Sung(1991)'s tool. "Liability on nursing terminal patients" was used as developed by Zarits(1980) and Mongomory(1985) translated by Lee(1985). For collecting data, preliminary investigation prior to 1 week of the hospice basic education program and post-investigations after 1 week and 4 weeks of the education were carried out for the nurses at a general ward who understood and agreed on the purpose of the program. Collected data were analyzed throughout t-test, $x^2-test$, Manova test and Bonferroni correction in $SAS^{(R)}$ program. The summary of the investigation is as follows: Hypothesis 1: "Educated experimental group would possess more knowledge on hospice compared to the un-educated control group" was supported after 1 (F=12.14, p=.00) and 4 (F=5.3, p=.02) weeks of education. Hypothesis 2: "Educated experimental group would take a positive attitude toward hospice nursing compared to the un-educated control group" was supported after 1(F=3.92, p=.05) and 4(F=5.05, p=.02) weeks of education. Hypothesis 3: "Educated experimental poop would feel less liability compared to the un-educated control group in nursing terminal cancer patients' was rejected. In this study, it was found that knowledge on hospice was significantly important. By applying hospice basic education programs to nurses, the education program helped nurses to take a positive attitude toward terminal patients. It was, however, seen that the education program had no effect on alleviating liability in nursing terminal patients. Therefore, it is expected that this educational program would help hospices and nurses at general wards to understand the concept and the role of hospice so that terminal patents, now neglected under current medical system, would be able to end their lives in peace.
