This research is designed for a consumer, not a supplier when it was designed. And the purpose is to present the reference data which is in order to improve the curriculum by analyzing the present subject of the curriculum. The research collected the curriculum for Dental Technology from a total of 20 schools --3-year colleges and 4-year colleges-- all in Korea. And we analyzed the average credits of subjects from students. As a result of this analysis, we get the conclusion below: 1. In a distribution which students answered about each subjects; Dental esthetic, Dental morphology I II, Dental morphology practice I II, and Seminar don't have many credits and mostly have a converged tendency in high points, according to the arithmetic mean of the major basis subjects. 2. In an analysis of the correlation which is based on the distinction of sex; Dental ceramics practice III, Medical terminology, Seminar, and The major basis subjects have a meaningful difference. (${\rho}$ < 0.05) 3. In an analysis of the correlation which is based on an age; The major basis subjects, and the application subjects have meaningful difference. (${\rho}$ < 0.05) 4. In a correlation coefficient between subjects; The correlation coefficient of the major application subjects is higher than the major basis subjects. According to the student ? t, we found that the level of significance is ${\rho}$ < 0.001, which is meaningful. We feel that Department of Dental Technology also highly need to design, and conduct focusing on a consumer who is working at the society, not a supplier. And we need to increase or decrease credits which have a meaningful difference.

Objectives : Currently, it is being reported that new health technology (HT) is introduced and spread throughout Korea at a very fast rate. However, the current status of new HT related to dentistry has not been known or studied. Therefore, this study aims to understand the present state and awareness on dentistry-related domestic new HT via surveys and research, and thus apply this as a reference to construct an effective new HT-related system in the field of dentistry. Methods : The assessment status of New Health Technology Assessment (nHTA) committee was searched on the website for any updates on new HT5). The cases were searched in the range between Jan 1 2012 and Jul 31 2016 by submission date and were analyzed by year, division of technology, progress and major operating practitioner. Among those, technologies utilized by dentists were additionally analyzed. The survey result was obtained by combining responses of 25 participants from the workshop for new HT application and 11 members of Korean Association of Oral and Maxillofacial Surgeons (KAOMS). The workshop was co-hosted by KAOMS and Clinical Translational Research Center for Dental Science (CTRC) under Seoul National University Dental Hospital (SNUDH). Results : Most of the respondents to the survey have heard of new health technology but were unaware of the application procedure. 'Safety and effectiveness' was selected the most for things to consider when introducing new HT, followed by 'scientific evidence of the technology.' For new dental HT status, submissions between 2012 and Jul 31 2016 were analyzed by major operating practitioner, including cases where there are multiple practitioners. Yet, only 19 cases (17 %) of dentists were reported. Among 385 cases approved by nHTA, only 2 cases included dentists. Conclusions : Active publicity by the government on new HT and its application procedure, and continued interest and research in the dental and medical community is likely to be required for the development of dentistry.

Objectives; The purpose of the present study is to investigate workplace satisfaction level of dental technicians and the differences between that of dental lab owner's and that of employed dental technicians, who are working in dental laboratories. Methods; Samples were comprised of 137 dental technicians working in dental laboratories. Data were collected through self-administered questionnaires and analyzed to frequency distribution, correlation, t-test and multiple regression analysis. Results; 1) Dental technicians generally are 'somewhat or a bit satisfied' with their workplace situations, regardless of position, sex, and individual career. 2) Mean values of 4 items out of 11 work situation factors of employed dental technicians were significantly lower than those of lab owner's. The 4 items are the openness of management, working environment, pay, and policy in promotion and raise. They would be sources of dissatisfaction and conflict. 3) Level of satisfaction was significantly correlated with 2 subordinate variables, i.e. working conditions and administration policy. There is a tendency that administration policy is a bit more important for lab owners, while working conditions are a bit more important for employed dental technicians. Conclusion; The employer-employee relationship of dental technicians seems to be sound, as no signs of troublesome problem is detected. But the discrepancy revealed in the above results is telling that there certainly exist some disagreement in the viewpoints of the two groups. It is necessary for the dental technicians to find ways to deal with the possible triggers of discord and discontent.
