"Stupa of Buddhist Monk, YeomGeo"(844) is known as the earliest Seon-stupa relic remains in Korean peninsula, from which, during late Silla and ealy Goryeo period, there were more than 30 of stupa was built on such canon. and became the well-known material culture in Seon Buddhism in late Silla period. In $9^{th}$ century, with the JeonDeong(delivering the light of Seon)from Tang to Silla, the culture of "GeonTapIpBi(building the pagoda and erecting stele)" was also moved in. And it was right after the style of monk's stupa had been methodically changed in china, from having the room in stupa for the corpse, named as "QuanShenSheLi", to the lessened stupa that contain the cremated. Analyzing the "Master ChengGuang's stupa"（807）and its stele, it can be found the correspondences of octagonal plan and the subjects of ornamentation to that of Stupas built in Silla, reveals they were made by the same canon. By the document in the stele, surmising the historical cause of alteration in Chan stupa, there was the most famous zen master ShenHui at the time, who has the most important role of making the NanZongChan to get the authenticity in Chan Buddhism. His reliqury was the first ${\acute{s}}ar{\bar{i}}ra$ casket discovered among Chan monks' relics, consequentially it was to influence to Chan cuture and size the monks 'stupa for his ${\acute{s}}ar{\bar{i}}ra$. The stupa of master ChengGuang, by its shape and geological location, is the lost piece in the Puzzle of Chan stupa culture between Silla and Tang.

Shipping and logistics safety, security system is strengthening worldwide, the development of shipping and logistics safety security core technology for national security logistics system construction has been carried out. In addition, it is necessary to localize the Array Detection System, which is a core component of the container search machine, to cope with the 100% pre-inspection of the container scheduled for 2018 in the United States. In this research, we propose a test software program developed by using TI-RTOS (Texas Instruments - Real Time Operating System) with a test digital signal processing board which is developed self development. We have developed a program that can test GPIO, SRAM, TCP/IP, and SDcard using M4 MCU. Also we propose a study on a self-developed Digital Signal Processing Board among the array detection systems that replace foreign products. We have developed a test board that can test M4 MCU and developed an X-Ray Detector Digital Signal Processing Board that combines MCU and FPGA.
