Objectives : The purpose of this study was to determine of fluoride-releasing of orthodontic resin cements containing fluoride and compare decalcification of tooth attached fluoride and non-fluoride resin cements. Methods : Total eighty premolar tooth were used in this study. Forty tooth were used for fluoride releasing measurement and forty tooth were used for decalcification measurement. Each forty tooth were randomly divided into four groups, and brackets were attached on tooth surface with Blugloo, Light Bond, Orthofolw(experimental groups) and Transbond cement(control group). After brackets were attached on tooth surface, forty tooth were immersed in artificial salival and then the quantity of fluoride releasing was measured ever day for 8days and then three-days intervals for 3 weeks. Forty tooth were immersed in decalcification solution for 48hours and then degree of decalcification was measured as lesion area, ΔF, and ΔQ using QLF. The data were analysed by one-way ANOVA and Pearson`s correlation coefficient using SPSS 12.0 program. Results : Fluoride release of experimental groups was higher than control group(p<0.05). Cumulative fluoride release of experimental groups was also higher than control group(p<0.05). There were the highest release during first day. ΔF, and ΔQ was high TB > BG > OF > LB (p<0.05). Change of ΔF, and ΔQ was also high TB > BG > OF > LB (p<0.05). As for correlation between fluoride release and lesion area, ΔF, and ΔQ showed negative correlation but there was no significant difference. Conclusions : This study shows that orthodontic reins cements containing fluoride release fluoride and prevent initial enamel decalcification caused by orthodontic treatment.

본 연구의 목적은 첫 현장실습을 시작하는 치위생과 재학생들에게 현장적응교육을 수행한 후 수행자신감과 실무능력의 향상 정도를 확인하는 것이다. 이를 위해 치위생과 재학생 30명을 대상으로 15시간 동안 현장적응교육을 시행하였다. 교육 전·후 자기기입식 설문지를 이용하여 수행자신감을 조사하였고 교육 후 간접 및 직접 실기 평가를 통해 실무능력을 측정하였으며 설문지를 통한 현장실습만족도를 조사하였다. 교육 전후비교는 paired t-test, 현장적응교육과 현장실습만족도와의 상관성은 Pearson’s correlation, 현장실습만족도의 영향요인을 파악하기 위해 선형회귀분석을 시행하였다. 교육 수행 후 재학생의 수행자신감, 간접실무능력 및 직접실무능력은 교육 전에 비해 증가하였다(p<0.05). 수행자신감, 간접/직접실무능력, 교육만족도과 현장실습만족도와의 연관성 분석 결과, 교육만족도가 현장실습만족도 중 ‘교육내용’, ‘현장실습에 도움’ 영역과 상관관계를 나타냈다(p<0.05). 이상의 결과에 따라 현장적응교육은 첫 현장실습의 적응력을 높이고 현장실습 만족도를 높이므로 향후 다양한 적응 교육을 개발하여 운영을 도모할 필요가 있다. The purpose of this study is to confirm the degree of improvement in performance confidence and executive ability after conducting field adaptation education to dental hygiene students who start their first field practice. Thirty dental hygiene students were evaluated with performance confidence, indirect and direct evaluation of practical skill before and after the field adaptation education was conducted for 15 hours. Also field practice satisfaction was investigated after field practice. A paired t-test was conducted to compare performance confidence, indirect executive ability, and direct practical ability before and after education. Pearson’s correlation was performed on the correlation between field adaptation education and field practice satisfaction. Linear regression analysis was performed to identify the influencing factors of field practice satisfaction. As a results, performance confidence, indirect and direct practical skills of after field adaptation program were increased than before that(p<0.05). The correlation between field adaptation education and field practice satisfaction showed that “education satisfaction” among the field adaptation education sub-regions correlated with “education content” and “support of field practice” among the field practice satisfaction sub-regions(p<0.05). Therefore, it is necessary to develop and management various adaptation education in the future as it increases the adaptability of the first field practice and increases the satisfaction of field practice.

중국 청조(淸朝)의 복식 문양과 18세기 프랑스 복식 문양 비교연구

김명은(Myung Eun Kim),배수정(Soo Jeong Bae) 한국복식학회 2014 服飾 Vol.64 No.7

This thesis aims to compare the representative costume patterns of the Chinese Qing dynasty and contemporary 18th century French costumes. As a research method, qualitative research was performed to compare and analyze the patterns of the flowers, the birds and pagoda shown in Qing dynasty and France. The results are as follows: The Chinese flower patterns used the embroidery technique for 3-step gradation colors to decorate flowers with less than 10 petals. Also, the forms of the flowers were large and simple in China. The flower patterns of the 18th century France is more similar to those of Qing dynasty than to the traditional French flower patterns. They used the drawing technique for the gradation colors and completed the work by embroidery. In the case of bird patterns, the crane on menswear, and the phoenix on women’s wear were applied to signify the symbolic feature of the Chinese symbolism. On the other hand, those in France were used solely for the division of the gender. As a result the clear form of the birds in China contrasted with the unclear forms of birds in France. During the influx of mandarine square to France from China, the application of crane and phoenix according to gender seems to be stressed emphatically without considering their symbolic meaning. In light of the pagoda pattern, Qing dynasty showed interest only in the form of pagoda, denoting the simple two-tier structure without detailed description. Whereas in France, the pagodas were three or four tiers, with gorgeous colors and much more detail than those of Qing dynasty. In conclusion, the main determinants of influences on the patterns of France from China would be forms, colors, constructions and technique of embroidery, along with the disregard for symbolic significance.

김명은(Kim, Myung-Eun),김희경(Kim, Hee-Kyoung),이명렬(Lee, Myung-Lyeol) 한국웰니스학회 2021 한국웰니스학회지 Vol.16 No.4

본 연구는 심폐소생술 시 개인의 성향(내향형, 외향형), 수행 자신감, 수행불안 그리고 수행스트레스의 심리적 측면이 가슴압박 깊이에 미치는 영향을 확인하여 심폐소생술 교육의 기초자료를 제시하는데 목적이 있다. 치위생과 재학생 52명을 대상으로 심폐소생술 시 가슴압박 깊이를 측정하였고, 가슴압박 깊이 측정 전 개인 성향, 수행자신감, 수행불안, 수행스트레스를 측정하였다. 개인 성향, 심리적 변인(수행불안, 수행스트레스, 수행자신감) 및 가슴압박 깊이는 평균과 표준편차를 산출하였고, 관련성을 확인하기 위해 Pearson의 상관분석을 실시하였고, 가슴압박 깊이에 영향을 미치는 요인을 파악하기 위해 성향과 심리적 변인을 독립변수로, 가슴압박 깊이를 종속변수로 하여 다중선형회귀분석을 실시하였다. 분석결과 연구대상자의 개인 성향은 3.24, 가슴압박 깊이는 33.96 mm, 수행불안은 3.26, 수행자신감은 2.99, 수행스트레스는 2.76이었다. 심폐소생술 교육경험이 있는 대상자가 경험이 없는 대상자에 비해 높은 수행 자신감을 나타냈고(p<0.05), 가슴압박 깊이는 성향, 수행불안, 수행자신감과 관련성을 보였다(p<0.05, p<0.01). 개인 성향과 수행 불안이 가슴압박 깊이에 영향을 미치는 것으로 나타났으며, 성향이 외향적일수록 가슴압박 깊이가 깊고, 수행불안이 클수록 가슴압박 깊이가 낮은 것으로 나타났다(p<0.05). 이러한 결과로 심폐소생술 시 적절한 가슴압박깊이를 확보하기 위해 심폐소생술 교육 시 개인 성향을 고려하고 수행불안을 제거하며 수행자신감을 고취시키기 위한 교육 방안 마련되어야 한다. The purpose of this study is to present basic data for cardiopulmonary resuscitation(CPR) education by examining the effects of disposition (introverted and extroverted), performance confidence, performance anxiety, and psychological aspects of performance stress on the depth of chest compression during CPR. The depth of chest compressions during CPR was measured for 52 students enrolled in the dental hygiene department, and disposition, performance confidence, performance anxiety, and performance stress were measured prior to chest compression depth measurement. disposition, psychological variables (performance anxiety, performance stress, performance confidence) and chest compression depth were calculated as mean and standard deviation, and Pearson"s correlation analysis was performed to confirm the relationship. In order to identify the factors affecting the depth of chest compressions, multiple linear regression analysis was performed with propensity and psychological variables as independent variables and chest compression depth as dependent variables. As a result of the analysis, the tendency of the subjects was 3.24, the chest compression depth was 33.96 mm, the performance anxiety was 3.26, the performance confidence was 2.99, and the performance stress was 2.76. Subjects with experience in CPR training showed higher performance confidence than subjects without experience (p<0.05), and chest compression depth was related to disposition, performance anxiety, and performance confidence (p<0.05, p<0.01). Personal disposition and performance anxiety were found to affect chest compression depth, and the more extroverted, the deeper the chest compression depth, and the greater the performance anxiety, the lower the chest compression depth (p<0.05). As a result, in order to secure an appropriate chest compression depth during CPR, it is necessary to prepare an educational plan to take into account tendencies during CPR training, to remove performance anxiety, and to inspire performance confidence.

국가 R&D 정보 공동활용체제 구축 방안에 대한 연구

김명일(Kim Myung-Il),전성진(Jhun Sung-Jin),류범종(You Beom-Jong) 한국콘텐츠학회 2006 한국콘텐츠학회 종합학술대회 논문집 Vol.4 No.2

국가연구개발사업은 각 부처 산하의 연구관리전문기관을 통해 관리ㆍ운영되고 있으며, 각 사업을 통해 생산되는 국가 R&D 관련 정보는 각 기관의 특성에 따라 구조적ㆍ의미적으로 서로 다르게 설계 및 구축되고 있다. 이러한 이유로 인해 정보 간 상호운용을 통한 국가 차원의 종합적인 수집ㆍ분석ㆍ활용이 불가능하며, 인력ㆍ성과 등의 R&D 기반정보가 중복 저장ㆍ운용되는 문제점이 발생한다. 이러한 문제점을 해결하고, 국가연구개발사업의 투명성 및 효율성 제고를 위해 과학기술혁신본부에서는 2006년 1월부터 국가 R&D 정보의 공동활용을 기반으로 하는 국가과학기술종합정보시스템(NTIS, National Science and Technology Information System)을 구축하고 있다. 본 논문에서는 국가 R&D 정보를 관리하고 있는 각 기관의 자치성 침해를 최소화면서, 공동활용의 효과를 극대화 할 수 있는 국가 R&D 정보의 공동활용 체제 구축 방안을 제시한다. National R&D programs are managed and operated by institutes under different ministries. The R&D information created through these programs are designed and constructed heterogeneously both semantically and structurally. Therefore, integrated collection, analysis and application of the information through the interoperability of information at the national level becomes nearly impossible, and redundant production and operation of R&D information becomes a general problem. The Office of Science and Technology Innovation has started the construction of the National Science and Technology Information System(NTIS), which is based on the interoperability and sharing of R&D information, to resolve these issues. In this paper, we propose a method to construct a system for sharing national R&D information held by different ministries while minimizing the effect on the autonomy of the institutes involved.

셀룰러 이동망에서의 우선순위 큐 기반의 2단계 호 수락 제어 기법

김명일(Myung IL Kim),김성조(Sung Jo Kim) 한국정보과학회 2003 정보과학회논문지 : 정보통신 Vol.30 No.4

멀티미디어 어플리케이션은 문자 위주의 어플리케이션과는 달리 데이타의 연속성 때문에 QoS(Quality of Service)에 매우 민감하다. 셀룰러 이동망에서 고속으로 이동중인 사용자의 멀티미디어 어플리케이션에 대해 QoS를 지속적으로 제공하기 위해서는 효율적인 호 수락 기법이 필요하다. 본 논문은 우선순위를 이용한 호 수락 제어를 통해 MH(Mobile Host)에게 지속적인 QoS를 제공하는 2SCA(2-Step Call Admission) 기법을 제시한다. 본 논문에서는 셀의 크기가 작고, 서로 중첩되어 있는 셀 구조를 가정하였으며, MH의 호를 신규호, 핸드오프호 및 QoS 상향조정호로 분류하여 각각 다른 처리 기법을 적용하였다. 2SCA 기법은 기본 호 수락제어와 응용 호 수락제어로 구성되어 있다. 전자는 셀의 가용 대역폭에 따라 호 수락을 결정하며, 후자는 기본 호 수락제어에서 블록킹된 호를 대상으로 각 호의 종류에 따라 DTT(Delay Tolerance Time), PQueue(Priority Queue), UpQueue(Upgrade Queue) 알고리즘을 적용하여 호 수락을 결정한다. 본 논문에서 제시된 2SCA 기법의 성능을 평가하기 위해, 신규호 블록킹률, 핸드오프호 드롭핑률, 대역폭 이용률을 측정하였다. 시뮬레이션 결과, 본 논문의 호 수락 기법이 CSP (Complete Sharing Policy), GCP(Guard Channel Policy) 그리고 AGCP(Adaptive Guard Channel Policy) 등과 같은 기존의 메커니즘보다 우수함을 알 수 있었다. Multimedia applications are much more sensitive to QoS(Quality of Service) than text based ones due to their data continuity. In order to provide a fast moving MH(Mobile Host) using multimedia application with a consistent QoS, an efficient call admission mechanism is in need. This paper proposes the 2SCA(2-Step Call Admission) scheme based on call admission scheme using priority to guarantee the consistent QoS for mobile multimedia applications. A cell proposed in this scheme are assumed to be small and overlapped with its neighboring cells. The calls of MH are classified into new calls, hand-off calls, and QoS upgrading calls. The 2SCA is composed of the basic call admission and advanced call admission;the former determines the call admission based on bandwidth available in each cell and the latter determines the call admission by applying DTT(Delay Tolerance Time), PQueue(Priority Queue), and UpQueue(Upgrade Queue) algorithms according to the type of each call blocked at the basic call admission stage. In order to evaluate the performance of our mechanism, we measure the metrics such as the dropping probability of new calls, dropping probability of hand-off calls, and bandwidth utilization.The result shows that the performance of our mechanism is superior to that of existing mechanisms such as CSP(Complete Sharing Policy), GCP(Guard Channel Policy) and AGCP(Adaptive Guard Channel Policy).
