정효경 대한치과기공학회 2016 대한치과기공학회지 Vol.38 No.4
Purpose:The intention of the study is to reveal the factors that influence the safety-behavior and safety-accident of the students of dental laboratory science. We intend to use the study as a basic data of searching effective ways to heighten the safety-behavior of clinical training and to prevent safety-accident. Methods: The survey was conducted on dental technology students. The collected data was analyzed by the statistical program SPSS 21.0. The results were analyzed by reliability, frequency, t-test, correlation, multiple regression. To test for significance on each item, p<0.05 has been decided as a standard. Results: The results of the study showed that the safety of the students was influenced by the school year, the leader of clinical training, clinical training environment and the experience of safety education. The safety-accident turned out to be influenced by the school year of the student and the safety behavior. Conclusion: Active leader of clinical training, clinical training environment that enables the safety-behavior, and the offering of the systematic safety education were the most important factors to heighten the safety behavior of the students and prevent the safety-accident. These factors were expected to not only induce the safety-behavior but also prevent the safety-accident as well.

치기공과 학생의 임상실습 만족도가 진로결정수준에 미치는 영향
정효경,곽동주,이종도 대한치과기공학회 2016 대한치과기공학회지 Vol.38 No.4
Purpose:This study aims to assess clinical practice satisfaction among dental technology students and to identify the factors that may influence their career decision levels. In doing so, the present study provides preliminary data as to ways to improve clinical practice satisfaction levels and career decision levels that would be optimal for one's competence. Methods: he survey was conducted on dental technology students. The collected data was analyzed by the statistical program SPSS 21.0. The results were analyzed by reliability, frequency, multiple-way ANOVA,correlation, multiple regression. To test for significance on each item, p<0.05 has been decided as a standard. Results: Analysis results indicate that the factors influencing clinical practice satisfaction of dental technology students include school year, satisfaction of major, area of clinical practice, and assigned department for clinical practice, while the factors that influence career decision levels include satisfaction of major and clinical practice satisfaction. Conclusion: Results of present study suggest that in order to improve clinical practice satisfaction among dental technology students and thereby career decision levels, one needs to focus on satisfaction of major and quality of clinical practice. Such efforts will enable a more active and effective approach toward clinical practice for the dental technology students, and with appropriate understanding and assessment of the experience, they will be better equipped to make a career decision where they can live up to their competence.

Full Zirconia Crown용으로 사용되는 block의 제조사의 굴곡강도와 임상작업후의 굴곡강도에 관한 연구
정효경,곽동주,Jung, Hyo-Kyung,Kwak, Dong-Ju 대한치과기공학회 2011 대한치과기공학회지 Vol.33 No.4
Purpose: The purpose of this study was to evaluate flexural strength of full zirconia crown using block after clinical work. Methods: The three point bending test was used to measure the flexural strength of zirconia block. Statistical analysis was done using the Statistical Package for Social Sciences version 19.0 for Windows. As for the analysis methods, the study used analysis of variance, Tukey's test. Results: The ave Rage value of flexural strengths of WIELAND, Zirkonzahn, Hass, D-MAX were 516.2 MPa, 612.6MPa, 566.2MPa, 744.6MPa. The ave Rage value of Surface Roughness of WIELAND, Zirkonzahn, Hass, D-MAX were 0.39Ra, 0.33Ra, 0.33Ra, 0.47Ra. Conclusion: Flexural strength of zirconia block decreased after clinical work. Flexural strength of zirconia block is equal to or higher than flexural strength of dental metal, so zirconia block can be used as dental material.
