The resignation rate within 1 year dropped from 44.5% to 8.3%(p=.034). Conclusions: The specialized six month mentoring program was effective in reducing early resignation rate.

오일러 알고리즘의 안내된 재 발명 : RME 기반 미분 방정식 수업에서 점진적 수학화 과정 분석 An Analysis of Progressive Mathematization in RME-Based Differential Equations Course

권오남,주미경,김영신 한국수학교육학회 2003 수학교육 Vol.42 No.3

Realistic Mathematics Education (RME) focuses on guided reinvention through which students explore experientially realistic context problems to develop informal problem solving strategies and solutions. This research applied this philosophy of RME to design a differential equation course at a university level. In particular, the course encouraged the students of the course to use numerical methods to slove differential equations. In this contest, the purpose of this research was to describe the developmental process in which the students constructed and reinvented Euler algorithm in the class. For the purpose, this paper will present the didactical principle of RME and describe the process of developmental research to investigate the inferential process of students in solving the first order differential equation numerically. Finally, the qualitative analysis of the students' reasoning and use of symbols reveals how the students reinvent Euler algorithm under the didactical principle of guided reinvention. In this research, it has been found that the students developed deep understanding of Euler algorithm in the class. Moreover, it has been shown that the experience of doing mathematics in the course had a positive impact on students' mathematical belief and attitude. These findings imply that the didactical principle of RME can be applied to design university mathematical courses and in general, provide a perspective on how to reform mathematics curriculum at a university level.

The purpose of this research was to identify nursing interventions performed by the ICU nurses from 2 university hospital in Taegu. For this research, I used the Nursing Intervention questionnaire developed by the Iowa Intervention Project and translated by korean specialists and professor concerned to the same field. In order to obtain the data, a special group of professor, head nurse, charge nurse, researcher was instituted. The special group work validataed 205 nursing interventions with agreement of more than 50% becuse the NIC(433 nursing intervention) survey process was too time-consuming and not appropriate for all labels. The data were collected from June 1 to 30, 1999 and analysed with SAS program. The obtained results are as follows; (1) 94 interventions were performed at least daily. (2) The most frequently used nursing interventions were Parenteral Medication Administration, Aspiration Precautions, Pressure Ulcer Prevents, Positioning, Airway Management, Cough Enhancement in rank. In conclusion, this research using NIC has helped to figure out the component to the ICU care in korea. The use of this results will contribute to enhance quality assessment and improve standard of ICU nursing.

권수미,김태균,유미경,이광원 대한치과보존학회 2009 Restorative Dentistry & Endodontics Vol.34 No.6

본 연구에서는 치수강이 개방된 근관와동에 5.25% NaOCl용액을 각각 다른 시간 동안 적용시킨 뒤 접착레진에 의한 미세인장결합강도의 변화를 측정하였으며, 10% sodium ascorbate를 NaOCl 용액에 일정시간 노출시킨 상아질에 다시 10분 동안 적용하여 결합강도에 미치는 효과를 연구하고자 하였다. 연구결과 본 실험에서 상부 치수강 상아질과 하부 치수강 상아질에 대한 결합강도는 모든 실험군내에서 유의한 차이 (p > 0.05)를 보이지 않았다. 5.25% NaOCl 용액을 적용하지 않고 치수강 상아질에 접착시킨 대조군에 비해 20분간 적용시킨 실험군에서는 결합강도의 감소가 초래되었으나 통계적인 유의성 (p > 0.05)은 없었다. 그러나 5.25% NaOCl 용액을 40분과 80분 동안 치수강 상아질에 적용시킨 실험군에서는 대조군에 비해 유의하게 낮은(p < 0.05) 결합강도의 변화를 나타내었다. 5.25% NaOCl 용액을 40분동안 그리고 10% sodium ascorbate를 10분간 처리한 실험군에서는 유의한 결합강도의 회복을 나타내었다. 그러나 5.25% NaOCl 용액을 80분 동안 그리고 10% sodium ascorbate를 10분간 적용한 실험군에서는 대조군에 비해 통계적으로 유의한 차이(p < 0.05)를 보임으로써 여전히 결합강도가 회복되지 못하고 있음을 나타내었다. 5.25% NaOCl 용액을 5분간 적용한 뒤 10% sodium ascorbate를 10분간 적용한 실험군에서는 오히려 대조군에 비해 높은 결합강도(p < 0.05)를 보여줌으로써 높은 회복효과를 나타내었다. Clinical suggestion for the limitation of application time of NaOCl solution is needed to avoid large reductions in resin-dentin bond strength. The aim of this study was to measure the change of -tensile bond strength after the various application time of 5.25% NaOCl solution to pulp chamber dentin in endodontic access cavity, and to evaluate the effect of 10% sodium ascorbate application for 10 min on bond strength after the treatment of 5.25% NaOCl solution. In this experiment, there were no statistical differences(p > 0.05) in bond strengths between upper chamber dentin and lower chamber dentin. NaOCl-treated group for 20 min did not show any significant decrease(p > 0.05) in bond strength than non-treated control group. In contrast to that, bond strengths of NaOCl-treated groups for 40 & 80 min were significantly lower(p < 0.05) than that of non-treated control group. 10% sodium ascorbate retreated group for 10 min after 5.25% NaOCl application for 40 min to chamber dentin showed the recovery of bond strength significantly. However, the bond strength of sodium ascorbate retreated group after 5.25% NaOCl application for 80 min was still significantly lower(p < 0.05) compared to the non-treated control group, which means the reductions in resin-dentin bond strength were not fully reversed. On the contrary, sodium ascorbate retreated group after 5.25% NaOCl application for 5 min showed significantly higher(p < 0.05) bond strength compared to the control group, which demonstrates its superior recovery effect. In SEM exminations of specimens retreated with 10% sodium ascorbate after NaOCl application for 40 & 80 min showed that resin tags were formed clearly and densely, but weakly in density and homogeneity of individual resin tag compared to the control specimen.

권은경,김은숙,곽주석,이황,이수종,임미경 大韓齒科保存學會 2002 Restorative Dentistry & Endodontics Vol.27 No.1

Black-pigmented bacteria have been implicated in the endodontic infections. This group of microorganisms includes Porphyromonass endodontalis, Porphyromonas gingicalis, Prevotella intermedia, and Prevotella nigresceus. The organisms display a wide variety of virulence factors that may be pertinent to acute endodontic infections. The aim of this study was to identify P.endodontalis, P.gingivalis, P.intermedia, and P.nigrescens by using special potency disk test, filter paper spot test, 16S rRNA gene-directed PCR, and API 32A. Microbial samples were collected from root canals of 33 intact teeth with necrotic pulp and/or apical periodontitis. Conventional laboratory methods were used for identification of the strains of black pigmented bacteria. Eighteen of 33 samples were positive for the growth of black-pigmented bacteria. Five colonies were cultured from each pure cultured colonies from Brucella agar plate. Seventy seven colonies were positive for the growth of black-pigmented bacteria. Thirty three of 77(42.6%) were identifed as P.nigrescens, 10 of 77(12.9%) were P.gingivalis, 6 of 77(7.8%) were P.endodontalis, 10 of 77(12.9%) were P.intermedia. On the contraty the reference strains of P.nigrescens, experimental strains of P.nigrescens was sensitive to kanamycin in special potency disk test. 16S rRNA gene PCR and API test after rapid presumptative identification methods. such as special potency disk test and filter paper spot test, would be accurate detection methods for black-pigmented bacteria.
