This paper is about the study on the failure mode identification of railway signaling embedded system thru which quantitative reliability and safety can be compared reciprocally. Frequency of each failure mode makes possible to compare the reliability of each system and frequency of dangerous failure is used as the measurement standards for system safety. Therefore, this paper provides both reliability-related failure mode and safety-related failure mode by modeling the railway signaling embedded system.

The lineage village is a very characteristic form of village in Korea. Although it was known as having established on the base of the Lineage Law, the complexities of political and economical structures played an important role in the process of establishing the village. The continuous political struggles between the scholar officials forced them to abuse the blood ties as well as the academic and regional relation. Using the disorder of land ownership system, the ruling elite made chances to expand the private land ownership, and these became the fiscal background of the formation of the lineage village and the agglomeration. The capital area's lineage villages were used of fiscal background by scholar officials lived in Hanyang. In the reason of political struggle, the initiator came to Osan-ri in late 16th Century. And in early 17th century, with a government dignitary, Shin Kye-Young, and with the reproduction of population, Osan-ri formed a typical lineage village with many clan households in the late of 17th century.

In this study, the performance of the DPRMs is evaluated and the measurement precision for the pile driving is presented. The DPRMs is a visual-measurement system for the pile rebound and the penetration movement using a high speed line-scan camera. But the measurement errors of the DPRMs are caused by the strong impact for the pile driving. Therefore, the DPRMs should guarantee its measurement values for the pile driving. For this reason, the performance of the DPRMs by the vibration signal analysis is studied. It is found from this study that the measurement values of the DPRMs are reliable.
