This study developed a portable respiratory training device to improve breathing stability, which is an important element in using the CyberKnife Synchrony respiratory tracking device, one of the typical Stereotactic Radiation Therapy (SRT) devices. It produced an interface for users to be able to select one of two displays, a graph type and a bar type, supported an auditory system that helps them expect next respiration by improving a sense of rhythm of their respiratory period, and provided comfortable respiratory inducement. By targeting 5 applicants and applying individual respiratory period detected through a self-developed program, it acquired signal data of 'guide respiration' that induces breathing through signal data gained from 'free respiration' and an auditory system, and evaluated the usability by comparing deviation average values of respiratory period and respiratory amplitude. It could be identified that respiratory period decreased $55.74{\pm}0.14%$ compared to free respiration, and respiratory amplitude decreased $28.12{\pm}0.10%$ compared to free respiration, which confirmed the consistency and stability of respiratory. SBRT, developed based on these results, using the portable respiratory training device, for liver cancer or lung cancer, is evaluated to be able to help reduce delayed treatment time due to respiratory instability and improve treatment accuracy, and if it could be applied to developing respiratory training applications targeting an android-based portable device in the future, even use convenience and economic efficiency are expected.

Youngsan is generally known as Pansori Danga(短歌). However, the contents of 'Yeongsan' in 『Songnamjabji』 are different. In 『Songnamjabji』, Cho Jaesam explained the contents related to 'Youngsan' using three kinds of poems: Shin Kwangsoo's poem, Baegho Imje's poem, Kim Myeongwon's poem. First, 'Ujo Youngsan' appears in Shin Kwangsoo's poem. Shin Kwangsoo wrote the (1750) when Yoo Jinhan's 『Manhwajib(晩華集)』(1754) was published. It is difficult to see the 'Ujo Youngsan', which appears in Shin Kwangsoo's poem written in a time when Pansori was not widely known, as the Pansori Danga. Second, Jo Jaesam called the music in Baegho Imje's poem 'Youngsan Dodeueum'. In 'Youngsan Dodeueum', flute and 'Dodeuli rhythm' were used. This fact is connected with , an instrumental music. , also a Buddhist term, continued to be used in the palace as well as among the people. Third, Cho Jaesam introduced Kim Myeongwon's poem in 'Yeongsan' part and called it 'Taryeong.' At that time, the term 'Taryeong' referred to both Pansori and Jeongga(正歌). Later, in the 19th century, 'Youngsan' was recorded as a term for the Danga to loosen the neck before Pansori began in earnest. In other words, the early 'Yeongsan' recorded in 『Songnamjabji』 was a Buddhist term, referring to the music of the upper class Seonbi, such as , Gasa(歌詞) and Sijo(時調). In 1855, when 『Songnamjabji』 was written, 'Youngsan' was used as a term used to refer to both Changbu-Music and Gagaek(歌客)-Music, mixed with the term 'Taryeong'. And as Pansori became popular, the term 'Taryeong' came to be called 'Pansori' and 'Youngsan' was used to refer to Pansori Danga. Therefore, all the records of 'Youngsan' should not be interpreted as Pansori Danga. This situation is closely related to religious and social change. The policy of worshipping Confucianism and suppressing Buddhism rejected the term 'Youngsan' which had a Buddhist meaning. In the middle of Joseon Dynasty, when Buddhism was suppressed, 'Youngsan' and 'Taryeong' were mixed. As Buddhism regrown in the late Joseon Dynasty, with the advent of Pansori, the term 'Youngsan' seems to be newly resettled in the sense of Danga. Pansori appeared in the 19th century and 'Yeongsan' was used as a Danga. And the reason should be regarded as this social and religious change.
