PDMS-PU 탄성체의 합성과 물성 및 Zwitterionization에 관한 연구

윤정욱,왕은진,백남철 慶熙大學校 材料科學技術硏究所 1992 材料科學技術硏究論集 Vol.5 No.-

The mechanical properties of polyurethane elastomer synthesized from hydroxybutyl-terminated polydimethylsiloxane(PDMS) of molecular weight 1000 and 4,4'-methylene diphenyldiisocyanate(MDI) were investigated. Hard segment content varied from 33% to 56% and various chain extender with 1,4-butanediol(BD), N-methyldiethanolamine(MDEA) or ethylene diamine(ED) were used in the segmented polyurethane block copolymer. The MDEA-extended materials were zwitterionized by using 1,3-propane sultone. By using gel permeation chromatography, infrared spectroscopy, differential scanning calorimetry and universal tensile Testing machine, physical and thermal properties of these polymers were investigated. All of these polyurethane elastomer showed phase separation. BD-extended material shows a higher tensile strength for the higher hard segment content material. MDEA-extended materials which were ionized by 1,3-PS exhibited better tensile properties than un-ionized copolymer. The zwitterionomer material exhibited ionic aggregation within the hard domain. Hard domain cohesion was found to be a important factor in determining the tensile properties of the elastomers.

윤순녕,김영임,최정명,조희순,김영희,박영남,오경순,이분옥,조선녀,조소영,한선희,하영미 韓國學校保健學會 2005 韓國學校保健學會誌 Vol.18 No.1

Purpose: The purpose of this study was to identify the needs of health education in students, their parents and teachers in the elementary, middle and high schools and the current situation of health education class. Method: The subjects of this study were a total of 9450 persons including students, their parents and teachers from 279 schools throughout the country. They were selected through convenient sampling. Data were analyzed through x^(2)­test and ANOVA. Result: Students, their parents and teachers replied that 18 dimensions of health education class (DHEC) are necessary. The four DHEC - healthier life style, sex education, mental health and safety education - showed high educational needs in students, their parents, and teacher. High school students had higher educational need of 'symptom management for daily living' than elementary and middle school students. Students, their parents and teachers in elementary school had higher educational needs of 17 DHEC that those in middle and high school. The percentages of schools with health education class taught by health teachers were 99.2%, 75.5% and 66.0% respectively in elementary, middle and high schools. Health education was given mainly using physical education classes at elementary schools, and creative class hours at middle and high schools. In general, health education took 1-3 hours per week at elementary schools, and less than an hour at middle and high schools. Conclusion: Therefore, based on the results, systematic health education class should begin from elementary school to meet the need of health education in students, their parents and teachers, and further study should be made on the number of hours required and the amount of contents of 18 DHEC.

정중재,박수정,조현구,황윤찬,오원만,황인남 大韓齒科保存學會 2008 Restorative Dentistry & Endodontics Vol.33 No.4

본 연구에서는 치과용 디지털 색상 분석기기 중 하나인 ShadeScan (CYNOVAD, Montreal, Canada)의 색상 분석의 정확성과 재현 능력을 평가하였다. 균일한 치아 배열을 가진 20대 성인 남자 8명과 여자 8명의 상악 인상을 고무인 상제 (Exaflex, GC, Japan)를 이용하여 채득하고, 인상에 A2 색상의 임시 크라운 제작용 자가중합형 레진을 주입하여 치아 모델을 완성하고, ShadeScan을 이용해 각 치아의 영상을 얻어 컴퓨터의 ShadeScan 프로그램으로 분석하였다. 그리고 측정 결과의 재현 능력를 평가하기 위해 2개의 치아 모델을 임의로 선택하여 각 치아마다 10회의 색상 측정을 시행하여 분석 결과를 비교하였다. 또한 분석된 영상의 동일 shade 간의 색차를 확인하기 위해 광중합 복합레진인 Gradia Direct (GC, Tokyo, Japan)와 shade guide의 CIE L^(*)a^(*)b^(*) 값을 백색과 흑색 배경판 상에서 spectrophotometer (Spectrolino, GretagMacbeth, USA)로 측정하고, ShadeScan에 의해 동일한 shade로 분석된 shade guide간의 색차를 계산하여 다음의 결과를 얻었다. 모든 치아에서 모델 제작 재료와 동일한 A2 색상므로 분석된 경우는 없었으며, 개개의 치아에서 전체 순면이 동일한 색상으로 분석된 예는 없었다. 또한 동일한 치아군에서 치아의 크기 , 형태 , 순면의 굴곡 등에 따라 서로 다른 색상 분포를 보였다. 재현성 평가에서 각 치아의 중앙부는 비교적 일정한 재현성출 보였으나, 절단부와 주변 부위는 재현성이 낮았으며, 동일한 shade로 분석된 shade guide 간에는 3 이상의 색차 (ΔE^(*))를 보였다. 이상의 결과는 치과용 디지털 색상 분석기기는 비록 높은 재현 능력은 가지고 있지만 정확성에 오류가 있음을 시사하며 , 따라서 이러한 기기를 이용한 색상 분석 시 좀 더 세밀한 주의와 다른 방법의 추가 사용이 필요하리라 사료된다. This study was done to evaluate the reliability of the digital color analysis system (ShadeScan, CYNOVAD, Montreal, Canada) for dentistry. Sixteen tooth models were made by injecting the A2 shade chemical cured resin for temporary crown into the impression acquired from 16 adults. Surfaces of the model teeth were polished with resin polishing cloth. The window of the ShadeScan handpiece was placed on the labial surface of tooth and tooth images were captured, and each tooth shade was analyzed with the ShadeScan software. Captured images were selected in groups, and compared one another. Two models were selected to evaluate repeatability of ShadeScan, and shade analysis was performed 10 times for each tooth. And, to ascertain the color difference of same shade code analyzed by ShadeScan, CIE L^(*)a^(*)b^(*)values of shade guide of Gradia Direct (GC, Tokyo, Japan) were measured on the white and black background using the Spectrolino (GretagMacbeth, USA), and Shade map of each shade guide was captured using the ShadeScan. There were no teeth that were analyzed as A2 shade and unique shade. And shade mapping analyses of the same tooth revealed similar shade and distribution except incisal third. Color difference (ΔE^(*)) among the Shade map which analyzed as same shade by ShadeScan were above 3. Within the limits of this study, digital color analysis instrument for dentistry has relatively high repeatability, but has controversial in accuracy.

체형분류 방법에 따른 체형 유형 간 비교 : 18~20세 여성을 대상으로 Between 18 and 24 years old Korean Women

이정임,남윤자 한국의류산업학회 2004 한국의류산업학회지 Vol.6 No.2

The purpose of this study was to compare somatotypes from various classification methods, to analyze the interrelation among each somatotype or each high frequency type, and to suggest the basis to interpret body size and shape more accurately. As a sample, the subjects were 97 Korean females between 18 and 24 years old. They were measured both anthropometric and photographic measuring in November, 1999. Their somatotypes were classified by three kinds of classification methods. The first method was based on the lateral view of body; the second involved Factor and Cluster analysis with the photographic measurements of anterior and lateral body, and the third involved Factor and Cluster analysis with the anthropometric measurements of whole body. The upper body was classified into three types, and the lower body was classified into 6 types from the lateral view of body. The bend-forward/q-2 was found to be the `High-frequency type from the lateral view of body', and the Straight/n-1 was found to be the 'Straight type from the lateral view of body'. From the classification by the analysis of photographic measurements, the anterior body was classified into three types, the lateral was classified into 4 types. The X/e type was found to be the `High-frequency type from the analysis of photographic measurements of anterior and lateral body'. From the classification by the analysis of anthropometric measurements, the whole body was classified into three types. The i type was found to be the 'High-frequency type from the analysis of anthropometric measurements of whole body'. The significant interrelation was certified among some somatotypes or some High-frequency types. We found that both the view of body and the statistical analysis would make the clear definition of each somatotype possible. In order to certify the representativeness of High-frequency type, further analysis would be required of subjects who were in the High-frequency type and their body parts were in the High-frequency range.

본 연구는 새로운 치과용 색체계 개발을 목적으로 현재 치과에서 사용되고 있는 Vita shade를 사용하는 9 제조사의 12종의 광중합형 복합레진과 1종의 치과용 도재의 색상을 diffuse/8° 수광 방식을 사용하는 분광색체계 (MiniScan XE plus, Model 4000S, Hunter Lab, USA)를 이용해 D65 표준광과 10도 관찰자 시야 하에서 CIE L^(*)a^(*)b^(*) 값을 측정하고 색상 범위를 분석하였다. 분석한 정보를 color sorting system을 응용한 CNU Cons Dental Color Chart의 색상 표현 방식인 T###에 치과용 수복 재료들의 범위를 적용하여 다음의 결과를 얻었다. 측정된 L^(*)a^(*)b^(*)값의 분포를 분석해 보면 L^(*)값은 80.40과 52.70 사이에, a^(*)값은 10.60과-3.60 사이에, 그리고 b^(*)값은 28.40과 2.21 사이에 분포한다. L^(*)값의 평균값은 67.40, 중앙값은 67.30이며, a^(*)값은 2.89와 2.91, b^(*)값은 14.30 과 13.90 이다. 이러한 분석을 토대로 CNU Cons Dental Color Chart의 T###의 첫 번째 숫자에 해당하는 L^(*)값의 각 숫자간의 차이는 2.0으로, 그리고 2번째 숫자인 a^(*)값의 각 숫자간의 차이는 1, 그리고 세 번째 숫자인 b^(*)값의 각 숫자간의 차이는 2로 정하였다. T555에 해당하는 L^(*)값의 범위는 66.0이상, 68.0미만으로, a^(*)값의 범위는 3이상 4미만으로, b^(*)값의 범위는 14이상 16미만으로 결정하였다. The purpose of this study is to develope new dental color-space system. Twelve kinds of dental composites and one kind of dental porcelain were used in this study. Disk samples (15 ㎜ in diameter, 4 ㎜ in thickness) of used materials were made and sample’s CIE L^(*)a^(*)b^(*) value was measured by Spectrocolorimeter (MiniScan XE plus, Model 4000S, diffuse/8° viewing mode, 14.3 ㎜ Port diameters, Hunter Lab. USA). The range of measured color distribution was analyzed. All the data were applied in the form of T### which is expression unit in CNU Cons Dental Color Chart. The value of L^(*) lies between 80.40 and 52.70. The value of a^(*) are between 10.60 and 3.60 and b^(*) are between 28.40 and 2.21. The average value of L^(*) is 67.40, and median value is 67.30. The value of a^(*) are 2.89 and 2.91 respectively. And for the b^(*), 14.30 and 13.90 were obtained. The data were converted to T### that is the unit count system in CNU-Cons Dental Color Chart. The value of L^(*) is converted in the first digit of the numbering system. Each unit is 2.0 measured values. The second digit is the value of a^(*) and is converted new number by 1.0 measured value. For the third digit b^(*) is replaced and it is 2.0 measured unit apart. T555 was set to the value of L^(*) ranging from 66.0 to 68.0, value of a^(*) ranging from 3 to 4 and b^(*) value ranging from 14 to 16.

The knowledge of the specialized fields has been changed rapidly in the both side of quantity and quality. A hyper media as a knowledge based system is so fixed in the linked media in mutual that we could not tell it information provision with the view of user. In this paper, we propose the way of offering intellectual and flexible information which is same with demand in the side of user, selecting, searching and composing the HyperText at the point of user's view through the design of knowledge media system, three concepts is used in order to challenge the knowledge media system : special document, agent system and ontology. The special document is a knowledge using special fields. The agent system is a homogeneous controller that operates on an application to ensure that its activities are coordinated with those of the others within the community, providing a uniform control mechanism. The last 3th concept, ontology is a language for exchanging knowledge, which is a message exchanged among agents to ensure the proper interaction among them. The combination of these three concepts is used designed the prototype of knowledge media system.
