막구조는 근래에 와서 대공간 구조 및 지붕구조에 가장 보편적으로 사용되는 경량 인장 구조물로 각광받고 있다. 구조용 막재는 풍하중 및 설하중에 충분히 감당할 수 있도록 강도와 내구성을 가지고 있어야 한다. 일반적으로 막구조 재는 PVC코팅 폴리에스터막, 실리콘코팅 유리섬유막, PTFE코팅 유리섬유막이 있다. 제직되는 원단의 크기가 한정되어 있기 때문에 재단 후 접착하여 제작한다. 이 때문에 이음부분이 나 재단부분에 코팅으로 인한 접착이 어려워 고온고압으로 접착을 한다. 이 연구에서는 실리콘코팅 유리섬유막의 접착시 어려움을 보완하기 위해 저온 Plasma를 이용한 처리법으로 방전에 의해 Plasma를 발생시켜 50w, 100w 출력으로 10분, 20분간 처리하여 그 결과를 접촉각과 SEM 관찰을 통해 표면처리를 관찰하였다. Plasma 처리로 인해 실리콘 표면층에 균열이 발생하고 표면이 갈라짐을 확인할 수 있었다. 접촉각측정 결과 Plasma 출력과 시간의 증가함에 따라 접촉각은 감소하였다. 실리콘코팅 원단에 저온 Plasma 처리한 후 표면 특성을 분석하고 원단을 접착을 시켜 박리 강도를 측정함으로써 막구조 원단의 접착력 향상에 대한 연구를 진행하였다. KS K 0533 접착포의 박리 강도 시험방법으로 실리콘코팅 원단의 박리 강도를 측정한 결과 플라즈마 처리 원단이 플라즈마 미처리 원단보다 박리 강도가 향상된 것을 확인할 수 있었다. 저온 Plasma 처리 시간이 증가할수록 표면의 젖음성을 향상시켜 접촉각을 낮추었다. 이는 곧 표면에너지의 증가를 뜻하는 것으로 접착력을 증가시켜 실리콘코팅 원단의 접착성을 시킴으로써 강한 강도와 내구성을 갖춘 막구조물의 개발에 기대되고 있다.

Yeong-am's 'Jeongwon (貞元)' stone monument, designated as the Jeollanam-do Cultural Heritage, is considered to be the oldest of the epigraphs in Jeollanam-do. Immediately after the discovery, the possibility of it being a Maehyangbi of Memorial Inscriptions was mentioned and attracted attention. However, there is an absolute age of the 'Jeongwon (貞元) of 2 years' (786), so despite it is a relatively early epigraph (金石文), there are not many papers on the theme related to this stone monument. I believe that this stone monument is a Maehyangbi (埋香碑). While reviewing and comparing the results of the existing research, I decoded the text from the 42nd character of the 4th line. As a result of the review, that was conducted, it was confirmed that this stone monument is truly a Maehyangbi (埋香碑). In particular, it was recorded in the literature of the late Joseon Dongguk-myungsanggi (東國名山記) that the letters of the Maehyangbi (埋香碑) are not recognizable. However, it is clearly stated that this stone monument is a Maehyangbi (埋香碑). Although there is no common expression for 'bury (埋)' or 'incense burial (埋香)' in the traditional Maehyangbi (埋香碑), which were popular in the late Goryeo and early Joseon Periods, it can be seen that it is a Maehyangbi (埋香碑) from the words "hide (呑藏)" and "10 bundles of fragrant incense (合香十束)" that are engraved on the stone monument with the name 'Jeongwon.' In other words, it is thought that it meant 'hide (呑藏)' instead of 'bury (埋)'. Circumstantial evidence for the monument of Jingamseonsa (眞鑑禪師), built in 888, contains the an epigraph from the Unified Silla Era. There is a phrase on it that says 'Plant incense on the shore (海岸植香)' on the monument of Jingamseonsa (眞鑑禪師), and it conveys its meaning without using the character 'bury (埋)'. As a result of the absence of the character 'bury (埋)' on the stone monument with the name 'Jeongwon', it is not considered as a Maehyangbi (埋香碑). However, there is evidence that the stone monument with the name 'Jeongwon (貞元)' is in fact a Maehyangbi (埋香碑) and it is also in the Geumpyoseok (禁標石; Forbidden Stone) around Gukjangsaeng (國長生) and at the entrance of Dogapsa Temple (道甲寺). The letters written on the gold sign suggest the possibility that the charcoal used to burn incense (香炭) at the royal tombs of King Jeongjo (正祖) was produced around at Dogapsa Temple (道甲寺) in Wolchulsan (月出山). Since the charcoal used to burn incense (香炭) is naturally related to incense (香), it has been shown that the area around Wolchulsan, where Dogapsa Temple is located, has a long history related to incense (香). The letters visible on the stone monument, the record of Dongguk-myungsanggi (東國名山記) in the late Joseon Dynasty, and the letters on the Geompyoseok (禁標石; Forbidden Stone), all show that the stone monument with the name 'Jeongwon (貞元)' is a Maehyangbi (埋香碑). Considering the fact that the earliest Maehyangbi (埋香碑) in existence is the Maehyangbi (埋香碑) in Yeongam (靈巖) Ippam-ri (笠巖里), which has two dates from 1371 at the end of Goryeo and 1410 at the beginning of Joseon, the stone monument with the name 'Jeongwon' which was set up in 786, would be the oldest Maehyangbi (埋香碑) that we know of. In addition, there is a historical significance in that the Maehyangbi (埋香碑) is proven in the record of Dongguk-myungsanggi (東國名山記), a document from the late Joseon period.
