수종의 NiTi 전동 파일 단면 형태 비교 및 pecking motion의 사용방법이 피로 파절에 미치는 영향

김재관,금기연,김의성 大韓齒科保存學會 2006 Restorative Dentistry & Endodontics Vol.31 No.2

본 연구는 현재 시판중인 Profile^(®), ProTaper^(®), K3^(®), Hero 642^(®), Hero Shaper^(®)를 단면을 비교하고 이들 5가지 NiTi 파일과 사용방법에 따른 피로 파절 소요 시간을 비교하고자 시행되었다. 각 NiTi 전동파일의 치근단 1/3을 temporary resin에 매몰시키고 다이아몬드 표면처리된 버로 잘라내어, 초음파를 이용하여 세척 후, 주사전자현미경으로 단면을 관찰하였다. 주기적인 피로 실험을 수행하기 위해, 회전속도, pecking 거리를 자동적으로 조절할 수 있는 장치를 제작하고 파일을 만곡된 상태를 재현하기 위하여 15도 경사진 금속 토막에 위치시키고 분당 300회전의 속도로 회전시켜 파일이 파절될 때까지의 시간을 측정하였다. 사용방법에 따른 실험군은 동적군과 정적군으로 나누고 pecking 거리는 3㎜, 6㎜로 하였다. 실험결과 동적군 보다는 정적군의 피로파절 소요시간이 통계학적으로 유의차 있게 짧았으며 3㎜, 6㎜의 pecking distance에 따른 영향은 나타나지 않았다. 결론적으로 NiTi전동파일은 pecking motion으로 사용하는 것이 피로파절을 줄이는데 도움이 될 것으로 사료된다. There are various factors affecting the fracture of NiTi rotary files. This study was performed to evaluate the effect of cross sectional area, pecking motion and pecking distance on the cyclic fatigue fracture of different NiTi files. Five different NiTi files-Profile^(®) (Maillefer, Ballaigue, Switzerland), ProTaper™ (Maillefer, Ballaigue, Switzerland), K3 ^(®) (SybronEndo, Orange, CA), Hero 642^(®) (Micro-mega, Besancon, France). Hero Shaper^(®) (Micro-mega, Besancon, France)-were used. Each file was embedded in temporary resin, sectioned horizontally and observed with scanning electron microscope. The ratio of cross-sectional area to the circumscribed circle was calculated. Special device was favricated to simulate the cyclic fatigue fracture of NiTi file in the curved canal,. On this device, NiTi files were rotated (300rpm) with different pecking distances (3㎜ or 6㎜) and with different motions (static motion or dynamic pecking motion). Time until fracture occurs was measured. The results demonstrated that cross-sectional area didn't have any effect on the time of file fracture. Among the files, Profile^(®) took the longest time to be fractured. Between the pecking motions, dynamic motion took the longer time to be fractured than static motion. There was no significant difference between the pecking distances with dynamic motion, however with static motion, the longer time was taken at 3㎜ distance. In this study, we could suggest that dynamic pecking motion would lengthen the time for NiTi file to be fractured from cyclic fatigue.

This study aims to Waterfront Development the present condition and its strategy of tourism merchandise in Japan In order to obtain objective material, the Waterfront Development the present condition and descriptive analysis as its primary method of analysis. In order to draw an inductive reasoning to understand the present situation, the study chose the method of case study as the secondary method of analysis through the field survey in the advanced countries of tourism. 1. It is necessary to establish a sustainable and organized policy and system through "periodic public hearings" in which local governments and universities cooperate. 2. An index for sustainable Waterfront Development should be developed by research institutions such as universities. 3. In order to construct a competitive theme park or the waterfront, which would require considerable time, technology and financial resources, the central government or local governments should seek foreign investment or make policies for tax cut down. 4. The direction for developing Waterfront Development tourism should be divided into tourism product development and tourism attraction development. 5. In order to actively confront the environmental change and establish an efficient marine tourism information system, a new program consisting of 3Cs of commerce, contents, and community should be developed. 6. Waterfront Development should take root in the social system and be standardized. 7. A gradual and systematic policy should be made by the local government in order to develop marine-leisure sports into lucrative regional business.

The purposes of this study were (1) to reexamine what were found by the survey on KNU Teachers College Students after the Pilot School Project (Ⅰ) in order to assess the possibility of .generalizing results of the survey across different groups of students who enter Teachers College after the Pilot School Project was implemented, (2) and to examine students' opinion toward the current procedures of assingning freshemen to departments or majors of the Teachers College. The subjects were freshmen of KNU Teachers' College from 1975 to 1777 academic year. However, the data pertaining to the students from 1975 to 1976 had been gathered while the survey on Teachers College Students after the Pilot School (Ⅰ) was being carried out. In order to collect the data with regard to the students entered the Teachers College in 1977, four different questionnaives were employed. The data were statistically tested by means of chi-technique only when it seemed necessary and appropriate. Major findings of this study are as following: (1) After the Pilot School Project was employed, there were general tendency in students' reason applying for admission to KNU Teachers College: Each academic year, approximately 40% of freshmen decided to enter the college to be secondary school teachers in the future. (2) Students' attitude toward the new procedures of screening college applicants, which was employed after the Pilot School Project, were negative in general. Furthermore, their negative attitude became stronger year by year. (3) The degree of students' satisfaction with their majors were relatively higher than that expressed by the students who entered the college before the Pilot School Project was employed. (4) Both students' criteria for selecting their majors and then reasons for changing their majors which they had been interested in applying were varied across time subjects and time. (5) The obtained contingency coefficient between departments and GPA students of each department earned during thir freshmen year was 0.831. It seems to indicate that majority of freshment tends to choose their majors according to their GPA rather than their interest or aptitude. (6) Approximately 67.73% of freshmen of the 1977 academic year accepted the end of the academic year as the most appropriate time for assigning them to departments they desire to enter. 7) Approximately 52.10% of freshment supported the idea of assigningas many students to the departments as they wish to enter, as far as it is possible, by adjusting the capacity of department, which is regulated by MOE. (8) Approximately 61.08% of freshmen claimed not to deduct their GPA when their first choice of department became impossible and turned down to the second or the third one.

Background: The purpose of this study was to determine the effectiveness of percutaneously place self-expanding metallic stent for the relief of biliary obstruction in patients with hilar cholangiocarcinoma. Materials and Methods: From November 2001 to December 2004, 48 patients with hilar cholangiocarcinoma were prospectively studied. After percutaneous placement of bilateral self-expanding, uncovered metallic stents, follow-up evaluation was carried out until July 2005. Results: There were 4 cased of Bismuth type Ⅱ,21 cases of Bismuth typeⅢa 8 cases of Bismuth type Ⅲb and 15 cases of Bismuth type Ⅳ. Stent placement was technically successful in all patients All patients had satisfactory biliary drainage, resulting in one week drainage rate of 72.8% and final drainage of 91.9% There were 12 cases (21.3%) of abdominal pain requiring analgesics and 1 case (7.1%) of cholangitis; both were successfully managed with conservative treatments. Late complications occurred in four patient (8.3%), including two patients with cholangitis, one patient with liver abscess, and one patient with biloma; all were appropriately managed by percutaneous drainage. The average length and median durations of stent patency and median survival time were 303 days (range, 60~815) and 338 days (range, 60 ~1175), respectively. Conclusion: Placement of a percutaneous metallic stent is an effective and safe method of palliation of patients with hilar cholangiocarcinoma.

五色의 意味에 관한 小考

김금주,김재웅 공주영상정보대학 1998 논문집 Vol.5 No.-

본고에서는 색채에 의한 음양 오행설과의 관계와 그 관념, 그리고 그에 따른 풍습을 많은 문헌의 예를 들어가면서 간략하게 살펴보았다. 그런 과정에서 얻어진 두 가지의 조그만 발견을 지적 해본다면, 첫번째는 고대의 완전한 사상체계인 음양오행설의 테두리 안에서 생성되어진 오색의 관념이 시대의 변화와 흐름에 동반하여, 점차로 원래의 속성과 그 상대성을 내포하고 있다는 점에 유의해 볼 필요성이 있다. 한 예로 그 당시에는 백색이 길흉과의 결합으로 인한 관념이 절대적으로 뿌리박고 있었을 터인데, 세월이 흐르자 어느 정도 상대적인 것으로 되어 버렸다. 일례로 중세기 초에 어느 서양인이 중국에서는 백색은 불길한 색이기 때문에 서양에서처럼 신부가 순백색의 웨딩드레스를 입는 습속은 도입되지 않을 것이라는 예언을 하고 있지만, 이러한 짐작은 보기 좋게 빗나가 지금 중국에 가면 북경이든 상해든 큰 도시의 웨딩 숍에서는 진열대에 가득 장식하여 영업을 하고 있음은 물론, 특히 대만에서는 웨딩드레스를 입고 영화 배우처럼 사진첩을 만들어 귀중한 물건처럼 보관함은 물론이고 주위의 친구들에게 기념으로 나누어주고 있을 정도이다. 그리고 본인이 알고 있는 몇몇의 중국 친구들 역시 횐 웨딩드레스에 대해 전혀 거부감을 느끼지 못한다는 대답을 듣고는 역시 민족적인 고유색의 관념도 변하고 있다는 것을 이해 할 수 있었다. 두 번째로는 쥐와 같이 상대성을 갖고 있으므로, 중국은 물론이고 주변 국가인 일본, 한국에 있어서도 음양오행설에 근거한 관한 습속들이 잔존하고 있다 위와 동일한 백색을 예로 들면, 거슬러 올라가 『삼국유사』에는, 단군이 아사달을 풍습으로 청하고 나라를 창건했다고 하는데 이 아사달은 백악(白岳)이라고 불리며 백주(白州)에 있었다고 적혀 있으며 조선시대에 있어서는 그것을 횐 산 즉 태백산맥이라고 지칭한 듯 하다. 이 역시 희다는 것은 오색설의 영향으로 고대부터 성스런 색이라고 존중되어 왔던 것이다. 그리고 현재에도 아이들이 정월이나 생일 등의 즐거운 날에 입는 화려한 옷에는 오색의 무늬가 새겨진 색동 저고리를 입는다. 이 역시 예로부터 자연스레 형성되어진 「피사진경(避邪進慶)」(액을 쫓아내고 경사스런 일만 불러들임)의미의 상징적인 색깔이며 아이러니컬하게도 민족적인 색채로서 친밀성을 갖게 되었으며, 무속 신앙에서 지내는 신에게 올린 제사에서마저도 오색보(五色布)가 쓰여지는 예로써 서울의 인왕산에 있는 국사당에서 행해지는 굿놀이 가운데서, 통로에서 출입구에 이르기까지의 나무에 오색의 천을 묶어 놓았는데 이를 외성황, 그리고 또 입구에서 본당에 이르는 통로에도 오색의 천을 묶어 놓고 내성황 이라고 부른다. 게다가 탈춤에서도 탈을 쓰고 추는 오방신장무 역시 그 관념의 잔영이며, 그 유명한 신라의 처용 전설에서부터 비롯된 처용무 역시 다섯 가지의 방위를 나타내는 다섯 명의 처용이 황색의 처용을 중심으로 춤을 추며, 오광대(五廣大) 놀이 역시 비슷한데 단지 오광대는 탈로서, 처용무에서는 의상으로서 오색을 구분하는 것이 차이가 일을 뿐, 오색의 관념에는 분명 차이가 없다. 결국 우리들이 평소에 상당히 민족적인 것이라고 여겨왔던 주위의 문화들이, 실제로는 중국의 오색의 영향을 얼마만큼 지대하게 받아 이제 까지 행해지고 있는가에 대해 생각해 본다면, 본 논문에서 다루어진 오색의 의미는 우리의 문화를 이해하고 연구하는 데에 중요한 길잡이가 되지 않을까 조심스레 여겨본다.

韓國人의 Toxoplasma Gondii 抗體價

金錦才 全北大學校 醫科大學附設 看護專門大學 1981 논문집 Vol.7 No.-

In order to determine the incidence of toxoplasma antibodies in Korean people, 72 medical and 166 nursing students were examined by Sabin-Feldman dye-test. Out of a total of 238 human sera from the Jeonbug University medical and nursing students, the overall positive rate was 41.6%. The difference in positive rate was observed between male and female, showing 33.3% and 45.2% respectively. There was a tendency that the dye-test titer of female is somewhat higher than that of male (medical students). The mode of transmission of the parasite to human was briefly discussed.
