  • 스펜스의 "천안문"은 고난에 찬 중국현대사를 마치 한편의 소설이나 영화처럼 생생하게 소개한 저작이다. 이 책이 지식인 중심으로 지난 백년간의 중국혁명을 서술했다면, 이스트만의 "중국사회의 지속과 변화"는 4세기에 걸친 근대 시기의 사회 경제사를 추적한다.

  • This paper proposes an implementation of SPARQL-DL, which is a query language for OWL ontologies, for query-answering over the OWL ontologies virtually generated from existing RDBs. The proposed SPARQL-DL processor internally translates input SPARQL-DL queries into SQL queries and then executes the translated queries. There are two advantages in the query processing method. First, another repository to store OWL ontologies generated from RDBs is not required. Second, a large ABox generated from an RDB instance is able to be served without using Tableau algorithm based reasoners which have a problem in large ABox reasoning. Our algorithm for query rewriting is designed to create one corresponding SQL query from one input SPARQL-DL query to minimize the overhead by establishing connections with RDBs.

  • Though the Platform Screen Door System (PSD) has received a positive evaluation and is installed in all the Urban Railroad platforms, PSD is not installed in the Intercity Railroad platforms. The limitation of PSD in the Intercity Railroad platforms is due to the fact that first, various types of trains such as KTX, Saemaeul, Mugunghwa, and Nuriro stop at the platforms and their locations of the doors are different and secondly, they are not operated under ATO (automatic train operation). RPSD system currently under research and development, on the other hand, is based on the improved door that slides up and down and can be installed in any Intercity Railroad platform regardless of the length of the train, the location of doors, and the number of doors. This study considers the mechanism of RPSD, develops a manual open/close algorithm, and evaluates the function of RPSD. The results show that the manual open/close algorithm achieves a significant improvement in efficiency when provided with power supply.
