조선시대 산릉조성에 있어서 간심에 대한 연구: 원릉을 중심으로
This thesis is about placing of royal tomb of Yeongjo(英祖) who is the 21st king of Joseon dynasty. The royal tomb of Youngjo was named Wonneung(元陵). There were many twists and turns when placing Wonneung site in Dongguneung(東九陵). The purpose of this study is to analyze Ganshim(看審, evaluating a site) which was given by administrators or geomancers in site selecting process at that time. And next is to scrutinize the effect of Ganshim on deciding the site for Royal tomb. More specifically, this study is to find the reason why Yeongjo could not be placed on the right side of his Queens tomb which was a chosen site before his dead. And also, this study is to discover why they chose the right area of Geunwonneung(健元陵, the first kings tomb of Joseon Dynasty) as Wonneung site among many options.
Through this study, it is found that the reason of not being placed in Hongneong(弘陵) heohuji(虛右地), which was his chosen site for his after dying tomb, is because of the so called jangyeongappijibeob(長年甲避之法). Burial time and Bungeom(分金, space angle coordinate) could be indicated as 60 gapja(甲子). According to Jangyeongappijibeob(長年甲避之法), if time and space angle match up as the same first letter of cheongan(天干), it is considered as an ominous case, and Hongneong was one of them.
There was some hesitation in making former Neung leong(寧陵) site as Won leong, but a problem of the great urgency surpassed this weak point. As a result, they could use the former tomb site as a new one by only changing back and head orientation, and it was the best way to change old to new without spending any time or manpower.
Over viewing of The Annals of the Joseon Dynasty(朝鮮王朝實錄) and Shan Leong Do Gam Yui Gwea(山陵都監儀軌), the conclusion is as follows. His new young Queen-Jeongsoon(貞純王后) is not to be blamed for Young Jo(英祖)s not being able to be placed on the side of his former queens tomb, Hong leong. And also, it is not because of Jeong Jo(正祖) though he had an authority to change it. Only because, there were an inharmony between the earth fortune and his death year.이 논문은 2016년도 원광디지털대학교의 교비 지원에 의해서 수행됨
Direct synthesis of nanotubes on suspended microheaters for low power gas sensors
학위논문(석사) - 한국과학기술원 : 기계공학과, 2017.2,[v, 51 p. :]오늘날 대기 오염이 심각해 짐에 따라 모바일 기기를 이용한 대기 환경 모니터링에 대한 관심이 높아지는 가운데, 금속산화물 가스센서는 크기가 작고, 가격이 저렴하며, 높은 감도를 보이기 때문에 모바일 기기용 가스센서로 각광받고 있다. 그러나 금속산화물 가스센서는 가스의 반응을 촉진하기 위하여 고온에서 작동되며 이는 큰 소모전력을 필요로 한다. 소모전력을 줄이기 위하여 MEMS 기술을 이용한 마이크로 히터 플랫폼과 고감도 나노 소재를 결합하려는 노력이 꾸준히 있었으나, 나노 소재 집적기술의 한계 때문에 소모전력을 줄이는 데 한계가 있었다.
본 연구에서는 금속산화물 1차원 나노 소재의 집적기술을 활용하여 초저전력 가스센서를 구현하고 그 성능을 검증한다. 최적 설계를 통해 제작된 공중부유형 마이크로 히터를 이용하여 실리콘 기판으로 누설되는 열을 줄였다. 또한 ZnO 나노와이어를 마이크로 히터의 국소 가열을 통해 합성하고, 이를 템플릿으로 액상증착법을 통해 치환함으로써, 표면적이 큰 나노튜브를 3Ⅹ110 이내의 영역에 집적하였다. 이를 통해 고감도, 저전력 센서를 구현할 수 있었다.한국과학기술원 :기계공학과
