      • 혈액 투석 환자에서 중심정맥 협착에 대한 스텐트 삽입술 : Wallstent Placement

        임대승,노상필,이유선,정승현,김보영,이정우,강정아,김정희,이민수,정준용,최시완,정진옥,성인환,이강욱,신영태 충남대학교 의과대학 의학연구소 2002 충남의대잡지 Vol.29 No.1

        Stenosis of central vein is a common complication arising after percutaneous subclavian vein catheter insertion performed for temporary vascular access in chronic renal failure patients undergoing hemodialysis. There are several treatment methods for the condition like percutaneous angioplasty(PTA), stent insertion, and surgery, but recent trend is toward PTA and stents. Among the patients diagnosed with chronic renal failure from March 1993 to May 2002 and undergoing hemodialysis through AV fistula, the 14 Patients in whom central vein stenosis arose were selected for the study. A total of 28 percutaneous interventions(5 PTA and 23 stent placement) were performed, and restenosis rate and the time taken till the restenosis in de novo lesions and instant lesions were compared. All 28 cases were operated successfully. The 14 cases that received both anigioplasty and stent placement initially. (de novo lesion : 14 cases), Among the 10 cases with de novo lesion that followed up more than 1 year, 3 cases are currently undergoing hemodialysis without restenosis, and the remaining 7 cases have recurred stenosis with the mean time to restenosis of 10.9 months. In the 7 cases in whom stenosis recurred, 11 interventions were done(instent lesion: 11 cases). 4 of these were using only ballon angioplasty with 100% restenosis rate and the mean time of 3 months until restenosis. The remaining 7 cases were using both balloon angioplasty and stent placement, also with 100% restenosis rate but with the mean time of 12 months until restenosis, which was later than the group receiving only balloon angioplasty. In treating the patients with central vein stenosis, stent placement seems to be more advantageous over PTA in terms of restenosis rate and the mean duration of patency. In the case of instent lesion, inserting the stent for the second time after stenosis recurred lengthened the duration of patency compared to performing balloon angioplasty alone.

      • 철근 콘크리트 구조물의 내진 구조 해석에 관한 연구 : 비탄성 지진응답을 고려한 동적해석을 중심으로 Of Dynamic Analysis for Considering Inelastic Seismic Response

        임희철,장정수 朝鮮大學校 建設技術硏究所 1999 建設技術硏究 Vol.19 No.2

        The objective of this publication is to present the state-of-art in inelastic dynamic and static approaches to the analysis and design of structures subjected to earthquakes. This emphasizes that the response of building structures in actual intense earthquakes in inelastic, and that such response can be realistically estimated only though inelastic dynamic analysis. Much of the discussion is focused on the controlled utilization of inelastic response in earthquake-resistant design of concrete structures.

        林永大,李貞姬 新羅大學校 1984 論文集 Vol.17 No.-

        This study focused on the functional and the spatial structure of "Oncheonjang" in Busan. The results were as follows; 1. Commercial landuse in the study area is functionally specialized though its lower landuse intensity than the CBD. 2. There is a tendency of functional changes along the streets. In particular, such runctions as eating houses, taverns and lodging facilities tend increase relat-ively, and occupy an important position among the functions. 3. Customers of commercial facitilies in the study area are mainly local inhabitants and tourist. This suggests the change of regional characteristics from a tourist resort area to a local shopping center. 4. Number of customers makes peak between PM. 7 and 8 in time, and spring and autumn in season. Most customers are men and come with their friends.

        STS에 대한 고등학생들의 견해에 관한 평가도구 개발

        임재항,강순민,공영태,최병순,남정희 한국과학교육학회 2004 한국과학교육학회지 Vol.24 No.6

        이 연구의 목적은 STS에 대해서 우리 나라 고등학생들이 가지는 견해를 알아보기 위한 평가도구인 HS-VOSTS(Korean students' views on STS)를 개발하는 것이다. HS-VOSIS문항을 개발하기 위해서 다음과 같은 연구과 정을 수행하였다. 우선, 문헌과 선행 연구 고찰을 통해 4가지 범주의 10가지 하위 범주와 관련하여 23개의 논제를 포함하는 STS 범주 체계를 설정하였다. STS 범주 체계는 정의ㆍ과학의 외적 사회학ㆍ과학의 내적 사회학ㆍ인식론의 네 가지의 커다란 범주로 구성되어 있다. 다음은 91f 범주 체계를 기초로 4단계에 걸쳐 문항을 개발하였다. 1단계에서는 각 논제에 대한 짝진술문을 기초로 학생진술 문항지를 작성하여 772명의 고등학생들(16.3세)에게 투입하였다. 2단계에서는 짝진술문 중 하나를 제거하여 문항의 진술문으로 하고, 분류된 공통견해를 답지로 하여 1차 다지선다형 문항지를 구성하였다 3단계에서는 고등학생 28명(16.5세)을 대상으로 반구조화 면담을 실시하여 그 결과 분석을 통해 2차 다지선다형 문항지를 구성하였다. 4단계에서는 2차 다지선다형 문항지를 고등학생 306명에게 적용하여 낮은 반응비율을 보인 답지들을 제거하여 최종 검사도구를 완성하였다. HS-VOSTS는 학생들의 STS에 대한 신념 및 견해를 알아볼 수 있는 유용한 도구로서, 그 결과는 교사뿐만 아니라 교육과정 개발자, 교과서 저자, 교육정책 입안자들에게 많은 시사점을 줄 수 있을 것이라 생각한다. The purpose of this study was to develop HS-VOSTS(High School Students' Views On Science-Technology-Society), which is an instrument that monitors high school students' views on STS. For this study, 23 multiple-choice items were developed on four categories. First, a categorial scheme was constructed. The categorial scheme was based on many instruments that evaluate students' understanding on STS, literature review, and STS learning goal that many researchers had asserted. Second, the multiple-choice items were developed. The development of the items was carried out through four steps. In the first step, some pairs of statement on each subordinate category were formed. Next, the student statement questionaries which were based on the pairs of statement were responded by 772 students. In the second step, the response written by the students were analyzed to common viewpoints and the first multiple-choice items were constructed. In the third step, the semistructured interview with 28 high school students was implemented and the second multiple-choice items were constructed. In the fourth step, the final version of the instrument was developed through the analysis of the students' response on the second multiple-choice items. HS-VOSTS is an useful instrument for monitoring students' beliefs and viewpoints on STS topics. The results of the students' responses to HS-VOSTS items reflect the students' own thoughts directly. These results will give some implications for the curriculum developers, the authors of text books and the educational policy makers as well as the teachers.

        직장남성의 성격특성과 의복디자인 선호도와의 관계 연구

        林靖恩,李明姬 服飾文化學會 1999 服飾文化硏究 Vol.7 No.5

        The objectives of this study were to investigate the relation between personality(activity, emotional stability, and dominance) and clothing design preferences, and to examine the differences of clothing design preferences according to demographic variables of men, Subjects for the study were 255 male white-collar workers ranging in ages from twenties to fifties, in Seoul and Kwangju City, Korea. The men with higher activity of personality preferred the double jacket with 4 buttons, the combination of light color jacket and dark trousers, glen check pattern jacket, herringbone pattern jacket, light beige color dress shirts. The higher the imotional stability, the higher the preferences on diverse patterns such as fine stripe, plaid, hound's-tooth check, and small check pattern. The men with higher dominance preferred dark blue color suit, glen check pattern suit, and necktie of red circle, and disliked the necktie of gray circle. The men in their 20's and 30's liked the single jacket with 3 buttons, the suit of fine stripe and the necktie of gray circle more than the 40's and 50's did. The middle income group liked herringbone pattern most among three income groups. The higher the men's age and income were, the more they liked the conservative style such as a single jacket with 2 buttons. The men who reside in Seoul liked the suit of gray circle, the jacket and trousers of same color, the patternless jacket, and the patternless suit more than the men in Kwangju. Therefore, the men in metropolitan area preferred conservative clothing image. Fine stripe pattern and patternless materials were preferred when men wore jacket and trousers of same color, while glen check pattern was preferred as the pattern of jacket when jacket and trousers of different color. Male white-collar worker liked single jacket more than double jacket, and preferred the dark blue color suit and necktie, patternless suit, fine stripe suit, and the pale blue dress shirs generally. The present findings provide that the presonality of male has influence on the clothing design preferences, and it is possible to infer men's personality by their attire.

        녹차 및 결명자 추출물의 교정용 브라켓과 치면 사이의 경계부에서 분리된 mutans streptococci에 대한 항균작용

        임성훈,서정순,윤영주,김광원,유소영,김화숙,국중기,이병래,차종희,박재윤 대한치과교정학회 2003 대한치과교정학회지 Vol.33 No.5

        본 연구는 치아우식증에 관련된 Mutans streptococci 표준균주 및 임상분리 균주의 성장억제를 유도할 수 있는 천연 생약추출물을 검색하기 위하여 실시되었다. 녹차추출물은 CHMC-2032를 사용하였으며, 결명자 추출물은 50% 에탄올을 이용하여 얻었다. 이들 추출물의 Mutans streptococci 표준균주 및 교정환자들에서 브라켓과 치면 사이의 경계부에서 분리된 각각 10 균주씩의 S. mutans 및 S. sobrinus에 대한 최소성장억제농도를 액체배지 희석법으로 구하였다. 그 결과 CHMC-2032의 S. mutans 및 S. sobrinus의 표준 균주, S. sobrinus의 대부분 임상분리 균주에 대한 최소성장억제농도는 5 mg/ml이었다. 그러나 결명자 추출물에 의한 S. mutans 및 S. sobrinus에 대한 세균 성장억제 효과는 미미하였다. 본 연구 결과 치아우식증의 예방적 측면에서 결명자차보다는 녹차를 마시는 것이 유리하며, CHMC-2032를 이용하여 구강양치용액을 제조하여 사용할 경우 교정환자를 포함하여 대부분의 사람에게서 치아우식증 예방 효과가 있으리고 추정된다. Mutans streptococci is the major causative factor in dental caries. Especially, orthodontic patients with fixed appliance are a risk group for dental caries. Because fixed appliances attached on teeth may change the environment of dental plaque, the enamel decalcification or dental caries around the bracket and band is a major side effect of orthodontic treatment. The aim of this study was to search plant extracts that have antimicrobial effect on mutans streptococci. Seed-extract of Casio tora were prepared with ethanol and CHMC-2032, the leaf-extracts from Camellia sinensis extract, was obtained extract, 2 type strains and 20 clinical isolates of mutans streptococci isolated from the interface between orthodontic brackets and tooth surfaces in the orthodontic patients were used in this study. The minimal inhibitory concentration of CHMC-2032 was 5 mg/ml on the S. mutans KCTC 3065, S. sobrinus KCTC 3088, and 8 clinical isolates of S. sobrinus. However, there was no antibacterial effect of seed-extract of C. tora on mutans streptococci. These data suggest that green tea may be more effective than the tea prepared from C. tora in the prevention of enamel decalcification or dental caries around brackets.
