The purpose of this study is to determine the effect of chitosan treatment on the bamboo charcoal dyed cotton knit. The K/S, CIE $L^*$, $a^*$, $b^*$ and Munsell values of dyed and chitosan treated samples were measured. As chitosan treatment concentration increased, dye uptake decreased progressively. The chitosan treated cotton knit showed a red tone and a yellow tone on the Munsell color system. The antibacterial property, deodorization performance, moisture regain, thermal transmittance property were improved by chitosan treatment. The bamboo charcoal dyed and chitosan treated cotton knit showed high colorfastness to dry cleaning and washing.

경흉부 심초음파에서 관찰된 엡스타인 기형: 증례보고 2례

김성희,Kim, Sung-Hee 대한임상검사과학회 2019 대한임상검사과학회지(KJCLS) Vol.51 No.2

엡스타인 기형은 삼첨판엽이 삼첨판륜에 붙지 않고 아래쪽 우심실 첨부 쪽으로 내려가 우심실 안에 붙는 심장 기형으로 대부분에서 20대까지 생존하는 것으로 되어 있으며 25세 이상에서는 심부전과 급사의 발생이 비슷하였으며 약 70%에서 2세까지 생존하고, 50%에서 3세까지, 5%이하에서 50세 이상까지 생존한다. 본 예를 통해 엡스타인 기형은 다양한 형태로 존재함을 경험하였고, 22세의 WPW 증후군이 동반된 예와 77세까지도 생존하고 있는 예를 보고하는 바이다. 아울러 심첨 4강 단면도에서 정상적인 심장구조는 승모판륜보다 삼첨판륜이 심첨 쪽으로 약간 내려가 있기는 하나 거의 비슷한 선에서 관찰되어야 하는데 그렇지 않다면 반드시 이 기형을 의심해 봐야 한다. 더 나아가 선천성 심장기형의 진단 및 예후를 파악하는데 심장초음파는 중요한 역할을 하고 있으며 필수검사로 임상에서 활용되어지고 있다. Ebstein's anomaly is attached to the right ventricle with the tricuspid leaf attached to the lower right ventricle without any attachment to the tricuspid annulus. Most patients in their 20s are alive. Patients older than 25 years of age are similar in the incidence of heart failure and sudden death, and survive approximately 70% from 2 years, and 50% from 3 years, from 5% to over 50 years of age. Through this example, Ebstein's anomaly exists in various forms. A 22 year old case with WPW syndrome and those who survived to 77 years of age are reported. The normal heart structure in the apical four-chamber view should be observed on similar lines, even though the tricuspid annulus is slightly lower than the mitral annulus. If not, there will be some doubt regarding this anomaly. Furthermore, echocardiography plays an important role in the diagnosis and prognosis of congenital heart disease.

김성희,오건택,Kim, Sung-Hee,O, Gun-Teak 한국과학기술정보연구원 과학기술정보센터 2006 Journal of Information Science Theory and Practice Vol.37 No.2

본 연구에서는 하이퍼 링크 구조를 이용한 웹 검색 알고리즘에 대해 살펴 본 후 페이지 품질을 측정하기 위해 웹의 하이퍼 구조를 이용하고 있는 알고리즘인 HITS와 PageRank를 분석하였다. 이어서 이들 방법을 이용한 검색 엔진인 Google과 Ask.com을 검색 알고리즘의 특성을 기준으로 분석하였다. 이런 연구는 미래의 웹 문서의 중요도를 평가하는 데 기초자료로 활용할 수 있으며, 웹 정보검색의 검색성능을 향상시키는 시스템 개발에 도움이 될 수 있을 것이라 생각한다. In this paper, after reviewing hyperlink based ranking methods, we saw various other parameters that effect ranking. Then, We analyzed the PageRank and HITS(Hypertext Induced Topic Search) algorithm, which are two popular methods that use eigenvector computations to rank results in terms of their characteristics. Finally, google and Ask.com search engines were examined as examples for applying those methods. The results showed that use of Hyperlink structure can be useful for efficiency of web site search.

김성희,최성호,조규성,채중규,박광균,김종관,Kim, Sung-Hee,Choi, Seong-Ho,Cho, Kyoo-Sung,Chai, Jung-Kiu,Park, Kwang-Kyun,Kim, Chong-Kwan 대한치주과학회 1997 Journal of Periodontal & Implant Science Vol.27 No.4

치주질환은 세균에 의한 감염성 질환으로, 기계적 치태제거에 의한 치료의 한계를 극복하기 위하여 항세균 제재를 통한 화학적 치태 및 세균제거가 필요하게 되었다. 전신적으로 항생제를 투여할 경우 유효농도의 유지를 위해 많은 양의 약물이 투여되어야 하고, 여러가지 부작용의 위험이 있으므로, 이러한 단점을 극복하기 위한 국소 약물 송달체계가 필요하게 되었다. 본 실험의 목적은 치주질환 치료에 가장 많이 쓰이는 tetracycline을 calcium sulfate와 혼합하여, calcium sulfate의 서방형 국소 약물 송달효과에 대해 알아보고자 함이다. Modified calcium sulfate paste 와 10% tetracycline을 혼합한 것을 실험 1군으로, calcium sulfate와 10% tetracycline을 혼합하여 완전 경화 시킨 것을 실험 2군으로, calcium sulfate와 10% tetracycline을 혼합하여 경화되기 전에 사용한 것을 실험 3군으로, tetracycline-ethylene vinyl acetate fiber를 실험 4군으로 하여 시간별 tetracycline 방출농도, 유효농도 지속시간, calcium sulfate의 흡수기간 등을 관찰하여 다음과 같은 결론을 얻었다. 1. 실험 1군은 실험 5주까지 유효농도($4{\mu}g/ml$)이상의 농도를 유지하였고, 실험 2군은 실험 9일까지 유지하였으며, 실험 3군은 실험 7일까지 유효농도이상의 농도를 유지하였고, 실험 4군은 실험 15일까지 유지하였다. 2. 실험 2군은 평균 11.8일에 완전 용해 되었고, 실험 3군은 14.8일에 완전용해되었다. 3. 실험 2군과 3군은 실험 1주까지 방출된 tetracycline의 농도에 유의차를 보이지 않았다(p<0.05). 이상의 결과에서 볼 때, calcium sulfate는 tetracycline과 혼합하였을 때 일정 기간 동안 충분한 양의 tetracycline을 방출시키고, $11{\sim}14$일 정도 후에는 완전히 녹아 없어지므로, 서방형 국소 약물 송달 제재로서 가능성이 있으리라 생각된다. Periodontal disease is a bacterially causal by disease, To remove plaque and bacteria, it has been necessary to prescribe chemical drug to patient to subjugate therapeutic unvalue by mechanical scaling. As a patient on a high dosage of the antibiotics to maintain the effective concentration may produce unfavorable side effects, this decase demands the Slow-release local drug delivery system. The object of the experiment is to study on the slow-release local drug delivery effects of calcium sulfate compounded with tetracycline that mainly used in periodontal disease. Experimental groups were divided into four classes as follow: Group 1 10% tetracycline compounded modified calcium sulfate paste. Group 2 : compounded and hardened 10% tetracycline and calcium sulfate. Group 3 : compounded 10% tetracycline and calcium sulfate, used Just before hardened. Group 4 : tetracycline-ethylene vinyl acetate fiber. In the four groups, release concentration, it's durability and the period of absorption by times are observed and concluded as follow: 1. An effective concentration($4{\mu}g/ml$) remained until 5 weeks in group 1, 9 days in group 2, 7 days in group 3, 15 days in group 4. 2. It was fully fused at 11.8 days average in group 2 and 14.8 days average in group 3. . There were no statistically significant results in tetracycline concentration until a week in group 2 and 3(p<0.05) These results suggest that tetracycline loaded calcium sulfate release sufficient tetracycline and fused in $11{\sim}14$ days, so calcium sulfate is useful carrier as slow release local drug delivery system.

This study was carried out to investigate the quality characteristics and storage of noodle with added flowering cherry fruit powder. Wet noodles were prepared at concentration of 1, 2, and 3% (w/w) of the fruit based on flour weight. Moisture content of the noodles with or without flowering cherry fruit powder was 33.09~33.50%. Ca, K and Mg contents of flowering cherry fruit noodle were increasing at increasing concentrations of flowering cherry fruit powder. Cooked weight, volume, and water absorption decreased with increased fruit powder, whereas turbidity increased. For Hunter's color values of noodles, L (lightness) and b (yellowness) values decreased with increasing concentration of flowering cherry fruit powder, whereas a (redness) value increased. For mechanical characteristics of the noodles, adhesiveness of cooked noodle with flowering cherry fruit powder were higher than those of control. The pH of flowering cherry fruit noodle was lower than that of control during storage. Bacterial counts of wet noodle with flowering cherry fruit powders were lower than those of the control on the 10th day of storage at $5^{\circ}C$. From the sensory evaluation of 20's, texture, taste, and overall preference were not significantly different between the control and the fruit groups, but the color scores of 2% and 3% flowering cherry fruit noodle were significantly higher than that of 1% fruit noodle (p<0.05). In 40's sensory evaluation, color and overall preference scores of flowering cherry fruit noodle were significantly higher than those of control. In conclusion, the results of this study were suggested that the addition of flowering cherry fruit powder in combination with flour was tended to improve antimicrobial effects during storage when compared to control.

김성희,김영종,김신,정태성,Kim, Seong-Hee,Kim, Young-Jong,Kim, Shin,Jeong, Tae-Sung 대한소아치과학회 2012 大韓小兒齒科學會誌 Vol.39 No.2

본 연구는 CBCT(Cone-beam computed tomography)영상에서 미맹출 치아 크기 측정의 재현성과 정확성을 평가하기 위해 시행되었다. 매복치를 주소로 부산대학교 치과병원 소아치과에 내원한 혼합치열기 환자 중 진단 목적으로 CBCT 채득에 동의한 환자의 미맹출 견치 및 소구치 69개를 대상으로 하였다. CBCT 영상에서 측정한 미맹출 치아의 최대 근원심 폭경 계측치와 동일한 치아가 구강 내로 완전히 맹출한 후 채득한 석고 모형에서 대상 치아를 digital caliper로 측정한 최대 근원심 폭경 계측치를 비교하여 다음과 같은 결론을 얻었다. 1. CBCT 영상에서 미맹출 치아를 계측하는 방법은 재현성이 높다(ICC=0.91). 2. CBCT 영상에서 측정한 미맹출 치아의 최대 근원심 폭경 계측치와 석고 모형에서 측정한 대상 치아의 최대 근원심 폭경 계측치는 높은 상관 관계가 있었다(r=0.91). 3. CBCT 영상에서 측정한 미맹출 치아 최대 근원심 폭경 계측치와 석고 모형에서 측정한 대상 치아의 최대 근원심 폭경 계측치는 통계적으로 유의한 차이가 있었다($p$ <0.05). CBCT 영상에서 측정한 미맹출 치아 최대 근원심 폭경의 계측치가 석고 모형에서 측정한 대상 치아의 최대 근원심 폭경 계측치보다 평균 0.2 mm 작게 측정되었다. 그러나 이러한 차이는 임상적으로 수용 가능한 수준이라 생각된다. The purpose of this study was to evaluate the accuracy and reproducibility of measuring the size of unerupted permanent tooth via cone beam computed tomography(CBCT). Ten children were scanned with dental CBCT, and 3-dimensional reconstruction of the dentitions were generated CBCT. Mesio-distal dimension and buccolingual dimension of the teeth were made directly on the model with a high-precision digitalcaliper and on the CBCT by using three-dimensional dental imaging software. Reliability and accuracy were assessed by using intraclass correlation and paired $t$-tests. ($p$ <0.05) The results were as follows : 1. Intraclass correlations were above 0.9 for Both the CBCT and the model measurements, showinghigh reliability. 2. Although there were high correlation values(r=0.91) between CBCT and model messurement methods, comparisons between the CBCT and model messurement methods showed a statistically significant difference($p$ <0.05). 3. The CBCT measurements tended to slightly underestimate by 0.2 mm. But, the systematic difference of CBCT measurements were clinically acceptable Therefore, CBCT measurement method can be used to measure the size of unerupted teeth in a sufficiently accurate way.

김성희,이희웅(Sung-hee Kim),Hee-woong Lee 한국정보과학회 1998 정보과학회 컴퓨팅의 실제 논문지 Vol.4 No.4

컴퓨터 그래픽스 프로그램은 그래픽 객체(graphical object)의 관리, 디스플레이(display), 그리고 객체들에 발생하는 이벤트(event)등을 처리해야 한다. 또한 다양한 그래픽스 라이브러리와 윈도우 시스템의 개발로 프로그램의 이식성(portability)이 한층 강조되고 있다. 이와 같은 기능들은 상당히 복잡할 뿐 아니라 많은 그래픽스 응용 프로그램에 공통되는 내용들이기 때문에, 이들을 하나의 툴로 개발하여 많은 응용 프로그램 개발자가 공통적으로 사용하고자 하는 시도가 계속되어져 왔다. 본 논문에서는 사용하기 편리하고, 다른 시스템으로의 이식이 용이하며, 객체 지향 기법으로 설계되었기 때문에 확장이 용이한 그래픽스 저작도구의 설계 및 구현에 대해 설명한다. Computer graphics applications require managing and displaying objects as well as handling events. There are a number of graphics libraries and window systems that can be used for these purposes. These modules are general in nature and quite complex, so it would be best if we provide these features as a toolkit or a framework to the general purpose graphics programmers. This paper presents a toolkit that is easy to use, portable, and well suited for the usual modeling and rendering tasks. The object-oriented programming techniques used in designing the toolkit make it flexible and extensible.

The ultimate goal of periodontal therapy is promoting the regeneration of lost periodontal tissue. The purpose of this study is to evaluate the effect of treatment using decalcified freeze dried bone allograft as a bone graft material. 47 intrabony defects from 27 patients with clinical diagnosis of chronic periodontitis were selected among those 24 defects were treated via flap operation only and designated as the control group, the other 23 defects were treated with decalcified freeze dired bone allografting via flap operation and designated as the experimental group. Clinical parameters including probing depth, loss of attachment, probing bone level and gingival recession have been recorded at 6th months, and the significance of the changes has been analyzed. The results are as follows : 1. Probing depths were reduced significantly in both control group($2.75{\pm}0.99mm$) and experimental group($3.69{\pm}0.97mm$) postoperatively(p<0.01). Experimental group showed significantly higher decrease compared to the control group(p]0.01). 2. Loss of attachment showed statistically significant decrease in both control group($1.77{\pm}1.08mm$) and experimental group postoperatively($2.70{\pm}1.55mm$). Experimental group showed significantly higher decrease compared to the control group(p]0.05). 3. Probing bone levels were reduced with statistically significance in both control group($1.08{\pm}0.97mm$) and experimental group($4.00{\pm}1.41mm$) postoperatively(p<0.01). Experimental group showed significantly higher decrease compared to the control group(p<0.01). 4. Gingival recession showed statistically significant increase in the control group($1.21{\pm}0.72mm$) and experimental group($1.00{\pm}1.09mm$) postoperatively(p<0.01). There was no statistical significance between the control group and the experimental group. On the basis of these results, treatment using allogenic decalcified freeze dried bone is effective in reducing probing depth, loss of attachment and probing bone level. Therefore allogenic decalcified freeze dried bone is an effective bone graft material in periodontal regeneration.
