In this work, nano-needle structures ate formed to solve problem, related to low density of quantum dots for nano floating gate memory. Such structures ate fabricated and electrical properties' of MIS devices fabricated on the nano-structures are studied. Nano floating gate memory based on quantum dot technologies Is a promising candidate for future non-volatile memory devices. Nano-structure is fabricated by reactive ion etching using $SF_6$ and $O_2$ gases in parallel RF plasma reactor. Surface morphology was investigated after etching using scanning electron microscopy Uniform and packed deep nano-needle structure is established under optimized condition. Photoluminescence and capacitance-voltage characteristics were measured in $Al/SiO_2/Si$ with nano-needle structure of silicon. we have demonstrated that the nano-needle structure can be applicable to non-volatile memory device with increased charge storage capacity over planar structures.

현대 한국불교의 사상은 『金剛經』을 중심으로 하고 있다고 해도 과언이 아니겠지만,불교역사에 있어서도 수많은 판본과 주석서가 그 중요성을 말해준다. 그러나 수많은 주석서들은 지나치게 현학적으로 기술되어 있거나 格外道理를 강조하다 보니 본문의 흐름이나 표현방식을 간과하고 있다. 이에 본고는 『금강경』 본문의 표현방식의 변화를 살피면서 본문을 좀 더 명확하게 분석하고자 하였다. 여기서는 구마라습역을 중심으로 하고 전재성과 각묵역을 참조하여 본문 분석의 기초를 삼았다. 그리고 『금강경』을 한역하면서 상하로 구분하거나 두 부분으로 구분한 학자들도 있지만 구분의 필연성보다 편의적 기준으로 나누어져 있었다. 그래서 본고는 卽非的 話法과 卽非是名的 話法을 분류의 기준으로 삼아 『금강경 』 본문을 두 부분으로 나누어 보았더니 전반부는 주로 즉비적 화법으로 표현되어 있었고 후반부는 즉비시명적 화법으로 이루어져 있음을 발견하였다. 이에 본고는 즉비적 화법과 즉비시명적 화법의 차이점을 분석하여 보임으로써 『금강경』후반부의 표현방식이 전반부의 표현방식과 배치되는 입장에 있다는 결론에 도달하였다. It is commonly recognized that contemporary Korean Buddhist thought is largely based on the Diamond Sutra [金剛經]. A considerable number of printings and commentaries attest to the importance of the Diamond Sutra in the history of Buddhism. However, many such commentaries are often written in a pedantic manner and ignore the original text's flow or mode of expression, by emphasizing supramundane principles outside the realm of ordinary conceptual thought [格外道理]. Therefore, this study attempts to analyze the Diamond Sutra [金剛經] more clearly by examining the changes in its mode of expression. In this essay, the analysis of the original text is mostly based on the commentary of Kumārajīva (鳩摩羅什: 344-413), with references to Jae-Seong Cheon's (金在星:2003) and Gakmuk's (覺黙:2001) translation. Though some scholars divided the Diamond Sutra [金剛經] into two parts when translating into Chinese, this was not due to inevitability but due to convenience. Therefore, this study attempts to divide the Sutra into two parts, classifying it as ‘Just-not Speech’ [卽非的 話法] and ‘Just-not but-named Speech’ [卽非是名的 話法]. I find that the former was mostly composed of ‘Just-not Speech’ [卽非的 話法] and the latter ‘Just-not but-named Speech’ [卽非是名的 話法]. Through the analysis of the difference between the two, this essay concludes that the Sutra's mode of expression in the two parts conflict with each other.

In general, collections in museum are kept in storage according to a preservation and administration program in long or short term, after conservators’ conservation treatment. Museum activities related to conservation science are common to do before and after exhibitions. That is, the museum collections include a flow mechanism, which circulate a space in where conservation science related activity is carried on centering around its storage. The purpose of this study is to suggest the design guidelines of a conservation area in a museum. The results of this study as follows. First, to program space planning, conservation area of museum is divided into 4 kinds of zone. Second, space for relics unloading in basically includes ‘unloading room’, ‘control room’, ‘worker room’, ‘unpacking room’, and ‘unloading tools storage’ and considers to install ‘outdoor arrangement space’, etc. In case of space for making relics collections, ‘arrangement room’ and ‘temporary storage’ are separately planned in order to arrange and temporarily store relics taken in. Conservation analysis space should be divided into 2 kinds of zone, ‘conservation analysis lab’ for analysis of collection characters and ‘restoration lab’ for conservation treatment in the bigger museum. In case of large-scale museum, conservation treatment space is basically classified with characters of museum collections. And it considers installing ‘waterlogged wood lab’, ‘painting’ clothes treatment lab’, ‘storage of treated relics’ etc. Third, for ‘the spaces for analysis treatment’, must consider activity contents and sizes of the department for scientific conservation every museum, can classify in detail required space, and must review the space for relics settlement in construction.
지도를 이용한 길 찾기 훈련이 성인 뇌졸중환자의 인지기능과 일상생활동작에 미치는 영향

본 연구는 지도를 이용한 길 찾기 훈련이 뇌졸중 환자의 인지기능과 일상생활동작 수행능력 증진에 효과적인 방법인지를 알아보고자 하였다. 뇌졸중으로 인해 편마비 진단을 받은 7명의 환자를 대상으로, 병원에 서 지도를 이용한 길 찾기 훈련을 일주일에 3회씩 2주간 실시하였다. 중재 전후 인지기능과 일상생활 동작수행 능력은 로웬스타인 작업치료인지평가(Loewenstein Occupational Therapy Cognitive Assessment, LOTCA)와 기능적 독립 평가(Functional Independence Measure, FIM)로 측정하였다. 연구 결과, 지도를 사용하여 길 찾기 훈련에 참여한 대상자에게서 인지요소의 하위 영역 중 시지각 영역과 공간지각 영역의 공간관계 항목에서 통계학적으로 유의한 증가를 보였다(p<.05). 또한, 일상생활동작의 하위 영역 중 이동하기 영역의 걷기/의자차타기 항목, 사회적인지 영역의 문제해결능력 항목에서 통계학적으로 유의한 증가를 보였다(p<.05). 따라서 본 연구 결과를 바탕으로, 뇌졸중 환자의 인지기능과 일상생활동작 수행능력 증진에 있어서 지도를 이용한 길 찾기 훈련의 적용 가능성을 확인해 볼 수 있었다. The purpose of this study is to investigate the effectiveness of the way-finding exercise using a map in rehabilitation of cognitive function and activities of daily living in patients with a stroke. For the seven patients diagnosed with hemiplegia from a stroke, we executed the way-finding exercise using a map in the hospital, three times a week for two weeks. Loewenstein Occupational Therapy Cognitive Assessment(LOTCA) and Functional Independence Measure(FIM) were used to measure the cognitive function and performance of activities of daily living before and after intervention. For the visual perception area and the spatial relations of the spatial perception area of LOTCA, scores were significantly higher than before intervention(p<.05). For the walk/wheelchair of locomotion area and the problem solving of the social cognition area of FIM, scores were significantly higher than before intervention(p<.05). The results of this study show that a way-finding exercise for patients with a stroke is a useful therapeutic approach by enhancing cognitive function and performance of activities of daily living.
