Most of the eunuches were from the lowest class or the slave during the form al period of Koryo dynasty, whose job were just limited to the miscellaneous work in the royal court. Also, they were not treated fairly and their public post were restricted by ‘Nambanchilpum(南班7品)’ Nevertheless, the eunuches could gain more influence starting to manage the royal treasury during the reign of ‘Yejong(睿宗)’, the 16th King. Royal authority had been weakened until the beginning of the reign of the King ‘Euijong(毅宗)’, which was partially due to the rough throne succession. That was why the King ‘Euijong(毅宗)’ tried to look for a way out by giving power to the eunuches. It was hard for the eunuches to get stablized influence by the 6th year of reign as ‘Daegan(臺諫)’ were opposed to giving more authority to the eunuches. The circumstance becam e still when one of the eunuch suicided and ‘Euijong(毅宗)’ reached a com promise with ‘Daegan (臺諫)’. However, the incident that an officer of royal secret inspectors striped off an eunchs formal uniform 4 years later became the turning point, and then ‘Euijong(毅宗)’ and the eunches started to gain more power. In the 12th year of ‘Euijong(毅宗)’s reign, ‘Jungham(鄭?)’ was appointed ‘Gwunjihabm unjihu(權知閤門祗候)’ and it proved the balance had been inclined. In exchange for being committed to strengthen royal authority, eunuches gained special favor of the King since the occasion. For example, ‘Euijong (毅宗)’ entrusted eunuches with supervising ‘byeolgunggongnab(別宮貢納)’. It seem s that the special favor was often abused and became one of the main triggers of ‘Musinran(武臣亂)’. It means effort to defense his sovereign power with eunuches is deeply related with the Rebellion(武臣亂), and the King ‘Euijong(毅宗)’ and his eunuches shared their joys and sorrows.
지능형 교통체계(Intelligent Transport Systems: 이하 ITS)의 제반서비스는 사용자가 요구하는 다양한 형태의 동적교통정보의 제공가능성이 전제되어야 한다. 이는 많은 데이터 및 정보들이 수집, 가공단계를 거쳐 최종 정보이용자에게 효율적으로 전달되어짐을 의미하며 이를 위해 GIS기반의 공간데이터베이스를 사용하게 된다. 현재 국내외에서 교통관련시스템에서 사용되는 공간데이터베이스는 시스템의 목적에 따라 상이한 설계와 내용을 가지고 있다. 이는 시스템간에 공간상의 위치정보를 공유함에 있어서 시스템에 맞는 적절한 변환과정을 거쳐야만 한다. 특히 실시간으로 정보의 공유가 필요한 경우는 더 큰 문제를 노정하고 있다. 본 연구에서는 ITS 서비스에서 사용되는 공간위치정보-동적위치정보, 정적위치정보-를 시스템간에 실시간으로 공유하기 위해 ITS Map Datum (기본이 되는 지형데이터)과 위치참조기법을 개발하고 실제 적용을 위한 한가지의 프로파일을 제안하였다. 또한 제안된 프로파일과 지리정보 소프트웨어를 이용하여 서로 다른 공간데이터베이스상에서도 교통정보가 제공되어지고 더 나아가 공유되어질 수 있는 가능성을 평가하였다.
