본 연구는 미수 허목의 정원 유적인 연천 은거당의 공간구성 및 정원적 특질을 구명하기 위해, "미수기언" 등의 시문과 고지도 그리고 소치 허련의 <연천 태령십청원도>를 중심으로 은거당의 입지와 핵심 정원인 십청원과 괴석원의 공간구성, 정원식물과 시설 등을 조사 분석한 것으로 연구 결과는 다음과 같다. 은거당의 건물은 안채, 사랑채, 별묘 그리고 행랑채 등이며 정원은 안채와 별묘 사이의 십청원과 녹봉으로 이어지는 후원 그리고 사랑채 전정의 괴석원 등으로 모두 괴석을 정원시설로 중요하게 활용한 것으로 확인된다. "십청원기" 등 기문 분석과 후손의 인터뷰 결과, 십청원은 하도를 표방한 용도서를, 괴석원은 낙서를 상징한 귀문원을 구현하고자 한 석정(石庭)의 형태를 갖는 정원으로 추정된다. 또한 십청원에 도입된 상록식물은 용도서에 등장하는 십장청(十長靑)의 식물과 일치하는데 이를 통해 맑고 시원한 이미지를 추구한 것으로 판단되며 괴석과 함께 활용함으로써 성리학적 격물치지(格物致知)와 불로장생의 도가적 이상세계의 소우주를 구현한 것으로 이해된다. 또한 괴석원과 주변에 도입된 화려한 화목과 화초는 귀문원에서 찾을 수 있는 변화의 용(用)을 의미하며 십청원의 상록식물과 대비를 이룬다. 더불어 은거당 정원에 도입된 괴석은 미수의 전서체에서 느껴지는 기이함과 동질의 미적 대상으로서 창고미(蒼古美)와 고태미(古態美)를 창출하고자 한 것으로 파악된다. 궁극적으로 미수는 상록식물로 바탕을 삼고 화훼류로 변화를 꾀하며 기(氣)의 체(體)와 골(骨)에 해당하는 괴석을 둠으로써 그 뜻을 더욱 견고히 한 것으로 추론되며 이는 은거당의 정원적 특질로 귀착된다. 본 연구에서 얻어진 은거당 정원의 의장적(意匠的) 특질은 향후 은거당 복원의 기초자료로 활용되기를 기대한다.

The study aims to investigate general characteristics of Jae-sil from an architectural perspective by grasping location, deployment, structure, and plan composition based on existing inhabited conditions in Jeollabukdo. Results derived from the study are as follows. First, the location of Jae-sil is classified into mountainous and village types, and the two types showed a similar distribution. The village type showed the most distribution in the foot of a mountain in the rear of village, while the mountainous type is close to graveyard. The Jae-sil were mostly exposed to south, southeast, and southeast, which was not significantly different from residence. For deployment of the Jae-sil, a "二" shaped house, where main quarter and gated building are parallel located, can be common, indicating that additional attached building is less required. Second, for the platform out of structural components, coursed masonry was conducted by using natural rocks, and placed were a prop on the platform, first line on processed foot stone, and others on natural foot stone. For pillar, front line round columns, while others square columns. The binding type of the upper part of pillar is dominated by jangyeosujang and sorosujang. For wooden frame structure, 5ryangs were the most distributed, and out of these, 1goju 5ryang was the most generally used. For a roof part, it was composed with gambrel roof with single eave, and the roof was constructed by placing traditional Korean tile roof on the top. Third, for a size of Jae-sil out of plan composition, although the facade and the side of it were presented in a diverse manner, 4 facade rooms and 1.5 side rooms were the most frequently presented, and all Jae-sil were equipped with front ceremonial space. For spatial composition of Jae-sil, main floored hall is placed at the center, and each room is placed on the left and right side to secure space for ancestral rite for participants of it, and for a house with 5 rooms or more, it shows that main floored hall and rooms are weighted from side to side.

The Punggi (風旗) is one of the meteorological instruments made in the Joseon Dynasty (朝鮮王朝). Its purpose was to observe the direction of the wind. It is estimated that it started its operation in the $16^{th}$ century at least. But it does not remain in a perfect form, like the Chugugi (測雨器) and the Supyo (水標). The Punggi (風旗) can only be found at old document data, while the stone used to build the Punggi still remains. Since the stone had been named as the Punggi-dae (風旗臺) by 和田雄治 (1917), the name has not been changed until now. The Punggi is currently located in the Gyeongbok-gung (景福宮) and the Changgyeong-gung (昌慶宮). Meantime, there have been several transfers of its position. However, 和田雄治 (1917)'s paper and the "每日新報" (Maeil-Sinbo, 1929) articles have provided new clues. Also, the word 'Hupungso (候風所)' was found in the "朝鮮王朝實錄" (The annals of the Joseon Dynasty) and the "承政院日記" (Daily records of royal secretariat of Joseon dynasty). A designed harbor where the ship was staying was usually considered a special section for wind observations. It is assumed that the Hupungso was in most of the harbors at that time. This paper assumes the Punggi and the Hupungso had a lot of interest in wind observations in the Joseon Dynasty. In this study, we'll look for contained information about the Punggi and the viewpoints about wind during the Joseon Dynasty.

The modern town houses in Philippines has been changed through Spanish colonization over 300years and American military administration in 20C. Especially Cebu, the first contemporary capital of colonized Philippines by Spain, has various cultural characteristics and historical remains including old houses. By the economy condition in Cebu growing up, Bahay na bato, stone and wood house, has been settled for the elite or middle class of Cebu around 19C influenced by Spanish or Europe and Philippines native house called bahay kubo. Bahay na bato shows a common features, as revealed in this study, which all of them has a two stories with cut stone curtain wall and wooden beam and lintel, fronting the main street by approaching directly from street. And spatial separating also shown by setting living space to upper level instead of using storage or entrance hall called zaguan in lower level. Bahay na bato studied here shows a particular appearances in elevation, having volada and elaborate geometric or floral window pattern, also playing a role for ventilation with vetanilas below volada and main window in section. They have a rectangular plan with caida, sala, comedo, azotea almost similar to Spanish and ealier colonial Mexico style mixed with Philippines traditional style showing the strong spatial separation functionally and space wideness for party occasionally.

For a locally compact Hausdorff space, we denote by $C_0(X)$ the Banach space of all continuous complex valued functions defined on X which vanish at infinity, equipped with the usual sup norm. In case X is compact, we write C(X) instead of $C_0(X)$. A well-known Banach-Stone theorem states that the existence of an isometry between the function spaces $C_0(X)$ and $C_0(Y)$ implies X and Y are homemorphic. D. Amir [1] and M. Cambern [2] independently generalized this theorem by proving that if $C_0(X)$ and $C_0(Y)$ are isomorphic under an isomorphism T satisfying $\left\$\mid$ T \right\$\mid$ \left\$\mid$ T^1 \right\$\mid$ < 2$, then X and Y must also be homeomorphic.

담관 결석은 동통뿐만 아니라 황달이나 담도염 또는 췌장염 등을 유발할 수 있다. 결석에 대한 내시경적 제거가 실패할 경우 체외충격파쇄석술이 요구될 수 있는데, 이 논문은 담관 결석환자에 대한 체외충격파쇄석술 적용에 있어 보다 더 적절한 선택 기준을 정하는데 도움을 주기 위함이다. 총담관 결석 환자 중 기계적 쇄석술을 포함한 내시경적 제거에 실패한 46명이 체외충격파쇄석술을 받았다. 46명 모두 체외충격파쇄석술 전에 내시경적 유두괄약근 절개술을 받았으며, 경비담도배액관의 삽입이 이루어 졌다. 사용된 쇄석기는 초음파 유도하에 결석을 포착하는 시스템으로 spark-gap type이였다. 쇄석 후 추가적인 내시경적 제거술이 이루어 졌으며, 결석이 완전 제거된 경우는 89.1%(41/46)였으며, 자연 배출된 경우는 6.5%였다. 쇄석 후 결석제거율은 결석의 수(단일: 82.8%, 둘-셋: 100%, 넷 이상: 100%)와 크기(33 mm 미만: 92.9%, 33 mm 이상: 83.3%)에서는 큰 차이가 없었으나, 결석들의 장축 길이 합과 결석이 위치하지 않는 부분의 총담관 길이 합을 비교하였을 때 완전 제거된 경우와 그렇지 않은 경우의 비가 1:1.4와 1:1.1, 그리고 가장 큰 결석의 직경과 결석하방의 총담관 직경을 비교한 경우는 그 비가 1:0.9와 1:0.4로 의미 있는 차이를 보였다. 결론적으로, 결석의 수나 크기보다는 총담관 내에 분쇄된 결석이 충분히 움직여 바스켓으로 포획될 수 있는 공간이 있을 경우에 체외충격파쇄석술 적용이 상당히 유용하나 그렇지 않은 경우는 경피적 담도경을 이용한 제거가 유용할 것으로 보인다.

Statement of problem: Silicone Index Tooth Tray impression system which does not use gingicord has a shortcoming. It takes time to remove internal wall of Silicone Index Tooth Tray for space of wash impression material. Purpose: This study was to evaluate whether providing certain space to impression body can prevent from doing complicated laboratory work. Material and methods: After mounting metal dies with shoulder and chamfer margins arbiturarily, SITT was produced using $Blu-mousse^(R)$. In one experimental group, wash impression was taken using $Fit-tester^(R)$ without removing interior surface of SITT and in the other group, wash impression was taken using $Fit-tester^(R)$ providing 0.5mm space in the SITT and then compared the differences in two groups. Results: 1. There was no significant difference between a group which did not allow space and a group which granted equal 0.5mm space. 2. There was no significant difference between gingival diameter, occlusal diameter of metal die that has shoulder margin and gingival diameter, occlusal diameter of metal die that has chamfer margin. 3. There was no significant difference between a group which did not take pick-up impression and a group which took pick-up impression through relining method using SITT 4. There was no significant difference between a group that poured immediately after taking primary impression and a group that poured after removing poured stone die. Conclusions: When taking an impression of an abutment using SITT impression system, it is considered to obtain clinically identical results between a group that did not grant a 0.5mm space within SITT for wash impression and a group which invest a space. Furthermore, it is considered possible to produce an individual die through secondary pouring.
