This study was conducted on 54 freshmen of the department of dental technology in D University to examine the effect of dental morphological practice mobile application utilization on the students' perception of class and satisfaction with learning. Major results of the study showed that satisfaction and utility towards functions of mobile application strengthened positive perception of dental morphology class, leading to improvement of satisfaction with learning, which suggested that functional convenience and utility in the use of applications were the effective factors for increasing the satisfaction with learning. Those results need to be given important consideration in designing the class using the mobile applications.

This study is analyzed to conduct better on-site practices with recognizing importance of the clinical practice of Dept. of dental technology and use it as a basic material in the clinical practice. Target people who are students studying dental technology in D college in Daegu were questioned by survey. Study results below 1. Average score of the survey about satisfaction of the operating method of clinical practice shows 3.26. In detail elements, 'credit assignment(10 credits)' is 3.65 as the highest score, 'execution period(vacation)' is 3.50, 'choice of the clinical practice organization' is 3.25, 'measures after practice' is 2.98 and 'pre-education' is 2.98 as the lowest score. 2. Through the real clinical practice, 'experience of new equipments and technology' is 3.64 as the highest score, 'choice of lecturer' is 3.61, 'guidance way' is 3.49, 'contents properness' is 3.44, 'environment of practice organization' is 3.36, 'evaluation way' is 3.35 and 'practical use of the evaluation material' is 3.18 as the lowest score. 3. The average score of survey about satisfaction after clinical practice of the participated students is 3.46 that is higher than both 'satisfaction about operating method(3.26)' about clinical practice of college and 'satisfaction about organization(3.44)' about environment of dental craft organizations and labs, guidance way of lecturer and evaluation. 4. In the improvement of distribution of the clinical practice evaluation, in the 'practice organization: college' viewpoint, '7:3' is 35.77% as the highest response, '6:4' is 25.20%, '8:2' is 22.76% and '4:6' is 16.26 in regular sequence. 5. In site evaluation reflection of clinical practice, 50% reflection is 32.93% as the highest percentage, 60% reflection is 26.83%, 20% reflection is 20.73% and 80% reflection is 6.10% in regular sequence. In attendance score, it shows percentage of reflecting 50% and 40% is 26.98%, students wanting to reflect 30% is 25.40%, reflecting 10% is 20.63% and no reflecting is 0%. In result of the analyzed data, clinical practice has to be studied more in considering that clinical practice is important point in education of Dept. of Dental Technology and also problems in college and on-site practice need improvements.

Purpose: The purpose of this study was to analyze the career barriers of students studying dental technology in D-College. Methods: This study targeted 490 college students studying Dental Technology in D-College. The survey about career barriers on this study consisted of 45 questions and was scored with 5-points per question. The corrected data was analyzed by SAS V8 for Windows. Results: The difference analysis of career barriers shows that differences exist depending on gender(p<.01) and serving military service(p<.05). Especially, female students(2.69) and male students(2.65) who didn't serve the military are more susceptible to career barriers. In the sub factors of career barriers, differences exist depending on and in order of gender, serving military service, experience studying one more year to enter the college, day and night, the affiliation of highschool graduated from, and hometown. The correlation between the sub factors of career barriers and perception of career barriers manifested 'Lack of self assurance'(0.84), 'Sense of physical inferiority'(0.76), 'Relationship with other important people'(0.73) and 'Lack of information on occupation' in order. Conclusion: In the factors affecting non-decision on the career, 'Lack of self assurance'(=0.2465) is the highest in terms of influence, followed by 'Difficulty in interpersonal relations’(=0.1801) and 'Lack of information on occupation' (=0.1391).

In manufacturing the all-ceramic crown whick look close to natural teeth, the effectiveness of the improved technique is expectected the technique of the heat treatment of gold plating coating die was experimented of a refractory cast model. The following results were obtainde 1. An advantage of build up on east die with out manufacturing veneer, crown, core, or masking(reduction of technical process, and retrenchment of time and money) 2. Esthetically more close to natural teeth than other technique 3. Easy to remove a refractors cast die 4. In manufacturing ceramo-metal crown the enomous effectiveness was obtainde on applying in the areas of cervical margin, the metal surface, and in the treatment of pinhole.

This study was performed to observe the microhardness change of the surface and the bonding strength between the porcelain and alloy specimens in order to investigate the effects of appended indium, tin and copper on interfacial properties of Au-Pd-Ag alloys. The hardness of castings was measured with a micro-Vicker's hardness tester. The interfacial shear bonding strength between alloy specimen and fused porcelain was measured with a mechanical testing system(MTS 858.20). The microhardness of Au-Pd-Ag alloy was increased by adding indium and tin, but not increased by adding copper. The shear bonding strength of Au-Pd-Ag-Sn alloy and Au-Pd-Ag-Cu alloy showed 87MPa, 57MPa. The higher concentration of adding elements showed the higher shear bonding strength.

Purpose: The author performed experiments on the microhardness and the marginal fitness of composite resins after polymerizing 4 kinds of composite resins on MOD standard specimens. Methods: For this study, in order to compare the microhardness and the marginal fitness of 4 kinds of composite resins. Results: The results are as follows. 1. In case of the microhardness, Tescera scored the highest among the four kinds of composite resins. 2. In case of the marginal fitness, Premise Indirect scored the highest. However, there was no statistically significant difference, all staying in clinically practical range. 3. Considering the above results, among the four kinds of composite resins, the author advises to use Tescera during teeth restoration which scored the highest in the micro- hardness. Conclusion: Conclusion: All of the composite marginal fitness were within the clinically useful range.

This study was performed to identify the current problem of The National Qualification Examination for Dental Technician and to provide suggestion for improvement of The National Qualification Examination System. This study was based on the questionaries answered by the professors in the department of dental technology of college and the members of Korea dental technician's society. The result could be summarized in the following. 1. The examination should be held not only in Seoul but in other areas simultaneously. 2. Prepartation of The National Qualification Examination should be entrusted to a committee composed of selected members of The Korea Dental Technician Association and selected members of professors in the department of dental technology. 3. The carrving practical examination should be continued and the method of grading should be change to ensure fairness, objectivity and balance. Specially colored wax can be used to prevent cheating in test. 4. The examination on the subject of "The Introduction Dental Anatomy" should be different for dental technicians and dental hygienists. And the subjects need to be divided into "Dental Morphology" and "Oral Anatomy".
