Air-jet기능을 장착한 멀티형 복합유닛 핸드피스의 사용 만족도 조사

김임선,최병환 대한치과기공학회 2015 대한치과기공학회지 Vol.37 No.3

Purpose : This study was to investigate usage satisfaction of multi type handpiece with equipped air-jet function Methods : The subjects of this study through the survey was conducted for fifty-nine dental technicians in Daegu and Gyeongsangbukdo from the May 7 to 19, after the June 23 to July 4 2014. The survey was about the function and quality through user testing environment by cutting zirconia specimens using appliance for zirconia. The collected date was analyzed by the statistical program SPSS Win Ver 19.0 for the satisfaction of handpiece and control system. To test for significance on each item, p<0.05 had been decided a standard. General characteristics and relationship between the handpiece and control system was performed correlation analysis. Results : The results of this study is as follows. 35 dental technicians had 1~2 years career in zirconia part as the highest 59.3%, 95% of subjects expected that the prospects for the zirconia material have bright prospects. The satisfaction of multi type handpiece and control system design and function showed a significant difference. Subjects satisfied with the design and function of the multi type showed negative correlation with those of Standard. The satisfaction of multi type handpiece showed 3.37 points of air jet, 3.05 points of noise level, 2.69 points of water flow rate, and 1.98 points of cruise function. Sample differences in all parameters showed a statistically higher difference. Conclusions : High-speed cutting mechanism of multi-type is recommended working with zirconia materials and the multi-type unit combined handpiece motor, air-turbine and air-gun will be expected the increase of user due to the high satisfaction of air jet.

Base-Alloy에 따른 치과 도재의 소성방법과 열순환에 따른 결합강도 비교

김임선(Kim, Im-Sun),민경진(Min, Kyong-Jin) 한국산학기술학회 2010 한국산학기술학회논문지 Vol.11 No.2

이 연구는 심미성과 내구성을 살릴 수 있는 보철 재료들을 선택하기 위해 각종 도재 보철 재료들의 열 순 환 전후 결합 강도를 측정하였다. 결합 강도 측정을 위해 시중에 시판되고 있는 base-alloy중에서 with Beryllium 금속과 non-Beryllium 금속 8종과 Zirconia 1종위에 각종 도재 제품들을 소성하여 열 순환 전 후 결합 강도 측정 다음과 같은 결과를 얻었다. 1) PTM(press-to-metal) 도재가 열 순환 시행 전후의 각각 73.2MPa, 59.2MPa로 높은 결합 강도를 보였다. 2) non-Beryllium 금속 위에 소성한 도재가 with-Beryllium 금속 위에 소성한 도재보다 결합 강도가 우수했다. 3) Zirconia 도재는 38.7MPa의 가장 낮은 결합 강도를 보였다. This study measured the bonding strength of various porcelain prosthesis materials before and after thermocycling to select prosthesis materials that can maximize beauty and tolerance. To measure bonding strength, various porcelain materials were baked on with-Beryllium metals, non-Beryllium metals 8group and Zirconia 1 group among commercially available base alloys, and measured the bonding strength was measured before and after thermocycling. The findings of this study are as follows: 1) PTM(press-to-metal) porcelain non-Beryllium metal showed the, highteat bonding strength each 73.2MPa, 59.2MPa before and after thermocycling. 2) The porcelain materials baked on non-Beryllium metal showed higher bonding strength before and after thermocycling than those baked on with-Beryllium metal. 3) Zirconia products showed the lowest 38.7MPa bonding strength before and after thermocycling.

치기공과 학생의 임상실습 스트레스와 임상실습 만족도의 연관성

강월,김임선,최병환 대한치과기공학회 2017 대한치과기공학회지 Vol.39 No.4

Purpose: This study aimed to identify the effects of clinical practice stress on clinical practice satisfaction and to provide basic data for clinical practice improvement strategies. Methods: 150 students who had clinical experiences in Daegu Health College from June 12 to August 11, 2017 were selected by convenience sampling method and analyzed 130 questionnaires excluding 20 incomplete questionnaires. Statistical analysis was conducted using SPSS (Statistical Package for Social Science) 22.0 for windows Results: The satisfaction on major and the type of residentice showed statistically significant effect on the clinical practice satisfaction. The training environment in practice and the interpersonal relationship conflicts mostly effect on clinical practice satisfaction. Conclusion : In order to increase the clinical practice satisfaction, it is necessary to consider ways to improve the practical training environment and reduce interpersonal conflicts.

실습 수업에서 일부 치기공과 학생들의 블렌디드 러닝과 전통적인 면대면 수업 비교 연구

강월,김임선,Kang, Wol,Kim, Im-sun 대한치과기공학회 2020 대한치과기공학회지 Vol.42 No.3

Purpose: This study aimed to verify whether blended learning is worth alternating with traditional face-to-face learning for some dental technology students in practice teaching. Methods: A total of 68 students were included in this study. They were divided into two groups to compare blended learning and traditional face-to-face learning. The experiment had been carried out over 15 weeks. The following tests were performed: test of instructional quality, test of learning satisfaction, test of perceived usefulness, and test of learning flow. The IBM SPSS software was used to analyze the data. Results: The learning satisfaction and the perceived useful of blended learning by students appeared to be higher than that of traditional face-to-face learning. However, there was no significant difference in the variables of traditional face-to-face learning and those of blended learning (p<0.05). Conclusion: Blended learning is an alternative to traditional face-to-face learning for some dental technology students in practice teaching.

Purpose: The purpose of the study was to determine the general characteristics of students in dental technology departments; the correlations among their immersion in learning, class satisfaction, and academic achievement; factors influencing online learning experience; ways to improve students’ class satisfaction; and basic data for designing effective online courses. Methods: A total of 300 questionnaires were produced and distributed to dental technology students from September 29 through October 8, 2020. The outcome was analyzed using IBM SPSS Statistics ver. 25.0. A significance level of α=0.05 was used for reliable verification. Results: Immersion in learning, class satisfaction, and academic achievement were relatively high among students who studied on a regular basis, and class satisfaction and academic achievement were relatively high among students who studied with almost no interruption. Concerning the correlations between academic achievement, immersion in learning, and class satisfaction in online learning, the correlation between academic achievement and class satisfaction was the highest at r=0.862. Class satisfaction was the largest factor that influenced academic achievement, and the higher students’ immersion in learning and class satisfaction were, the higher their academic achievement was. Conclusion: The research is a case study that investigated the general characteristics of dental technology department students and the correlations among their immersion in learning, class satisfaction, and academic achievement. The study outcome could be used in determining factors that influence online learning and designing effective online courses that improve learner satisfaction.
