On-Board Signaling equipment for the rail car is similar as a nerve network of human body which needs high reliability and stability. Busan metro line 1 was opened to the public on July 1985 and it is providing reliable and stable large-scale transportation for the Busan citizens up to the present. But, for 24 years of long operation, equipments are being obsolete and it is now facing several problems on maintaining and repairing the product because spare parts of the equipments are no longer manufactured. Specially, ATC/ATO train signaling equipments of Busan metro line 1 needs to have continuous support and functional upgrade because of relatively long runtime and unstable running environment which is different from ground signaling equipment. In this paper we have improved the difficulties of analysing and preventing recurrence of malfunction on the ordinary train signaling equipment which is unable to save and view the processing information data because limitations of circuit organization and usage of supplier's hardware & software. Specially our proposed platform is compatible with ordinary imported product in installation method and functional structure. Also it can be connected with ground signaling equipment of Busan metro line 1. In this research, we have studied overall improvement by means of "Function extend-type digital ATC/ATO train signaling equipment for Busan metro line 1" which has possibility of changing driving method according to the train stopping on regular position algorithm

用法이 겹치는 助詞에 대한 考察 : 格助詞를 中心으로 on the Basic Case Proposition
김봉택 건국대학교 1995 學術誌 Vol.39 No.1
A postpositional word is basic to the sentence construction, exposing its qualification to an independent word over the other independent word. Those postpositional words are characterized by their unique ways of using, but they are frequently used overlapping each other in very similar ways. In these occasions, there are some significant differences in word feeling and grammer, in particular. We may fall into a feat error by being ignorant of the way of using these postpositional words correctly. In korean language the postpositional words are being used correspondingly, thus easily mistakenly used without our full understanding of the postpositional words of Japanese language. In the study, an investication was attempted to expose the character of it in terms of overlapping each other, and the differences of in grammer and words felling. This study also suggests some ways of utilizing as learning materials in the methods of teaching Japanese language.
