Objectives: This study aimed to provide the measures for improving the self-directed learning ability and the reference data for substantializing the educational programs by verifying the main factors affecting the self-directed learning ability of dental hygiene students in reality when the learners' autonomy is emphasized than ever. Methods: From June 20 to July 4, 2022, an online survey was conducted targeting total 218 dental hygiene students. The collected data was analyzed by using the SPSS Program Version 22.0. Results: First, in the results of analyzing differences in detailed items of self-directed learning ability according to the general characteristics, the 'students who entered the department of dental hygiene by considering their aptitude and interest' showed higher results than the 'students who entered the department by considering their high school record'. Second, when the academic efficacy, study immersion, and problem-solving ability of dental hygiene students were higher, their self-directed learning ability was also high. Third, the factor that had the greatest effect on self-directed learning ability of dental hygiene students was problem-solving ability, which was followed by academic efficacy and study immersion. Conclusion: Putting together the results above, in order to cultivate the problem-solving ability of dental hygiene students, it would be necessary to operate the problem-solving-centered simulation course that could foster critical thinking, interactions with others, and creative approach and solution to problems in dental medical site. It would be also possible to improve their academic efficacy by applying the learning mentoring & one-to-one learning counseling program, and also strengthening proper feedbacks for learners. Moreover, the study immersion could be strengthened by developing and operating the emotion-based learning motivation program & learning coaching program through the process of verifying the potential and growth needs of learners, exploring one's own resources through learning diagnosis/introspection, and exploring the career-related vision for strengthening the learning motivation, which could have positive effects on the improvement of self-directed learning ability.

The realistic problem about the dental hygiene education in our country is what the correlation between theoretical education and clinical education is short, and what the systematically clinical-practice education is failing to be realized. In order to solve this problem, the aim is to introduce preceptor and to present necessity in order to apply preceptor to the practice education for dental hygiene department. 1. What is the largest in the difference between the observation experience and the performance experience by element in clinical-performance activity is the patience-care service sphere(P < .001). 2. A hospital with the highest observation-practice experience level in children with the observation experience by hospital was in order of K hospital, Y hospital, H hospital, B hospital, and A hospital(P < .001, P < .01). 3. A hospital was the highest in the difference of the performance-practice experience level by hospital. And, the next was in order of H hospital, Y hospital, K hospital, and B hospital(P < .001, P < .01). 4. As for recognition on importance of clinical-practice activity in dental hygienists, the dental hygienists with more than the third year were indicated to be the highest than the dental hygienists with less than the 3rd year among 58 dental hygienists. Given seeing the results of this study, the more systematic and educational clinical-practice environment will need to be improved by suggesting a role of preceptor and to seek for a plan for application in the clinical-practice education.

Objectives : The purpose of this study was to investigate the effect of non-thermal atmospheric pressure plasma jet(NTAPPJ) on surface properties and Streptococcus mutans disinfection of denture base resin. Methods : Self-cured denture base resin (Jet denture repair resin, Lang dental Mfg, co., USA) was used to make specimen($12mm{\times}2mm$). To observe surface change before and after plasma process, surface roughness and contact angle were measured. For sterilization experiments, the surfaces of specimens were treated with nitrogen and air NTAPPJ for 1 minute after S. mutans was inoculated on the material surfaces. Results : Before plasma process, surface roughness of denture base resin was $0.21{\mu}m{\pm}0.02{\mu}m$. After air and nitrogen NTAPPJ process, surface roughness was $0.19{\mu}m{\pm}0.03{\mu}m$ and $0.18{\mu}m{\pm}0.01{\mu}m$ respectively. There was no significant difference(p>0.05). Contact angle of control group without plasma process was $83.81^{\circ}{\pm}3.14^{\circ}$, while after plasma treatment, contact angles of air NTAPPJ and nitrogen NTAPPJ groups were $63.29^{\circ}{\pm}2.27^{\circ}$ and $46.68^{\circ}{\pm}5.82^{\circ}$ respectively. The result showed a significant decrease in contact angle after plasma process(p<0.05). Compared to the control group 6020.33(CFU/mL) without plasma process, CFU decreased significantly after air NTAPPJ 90.75(CFU/mL) and nitrogen NTAPPJ 80.25(CFU/mL) treatment(p<0.05). Conclusions : It was considered that NTAPPJ can be used for denture disinfection without changing surface properties of materials.

The purpose of this study is to analyze and compare dental hygine curriculum of three countries--Korea, U.S.A., and Japan--, focusing on the ways of organizing content. In this study, 30 curriculum documents of dental hygienist in U.S., Japan, and Korea were analyzed and discussed by a framework of analysis which was constructed referring to Tylerian curriculum model. Using this framework, three kinds of key components of curriculum document were compared according to specific elements of each component. More specifically, comparing those curriculum documents, we must consider the dimension of content organization. In this study, the problem of course organization was viewed on three dimensions: continuity, sequence, and integration of curriculum content. Based on the results of this study, the conclusions are as follows. 1. Courses of dental hygienist education should be organized so that the curriculum foster the cumulative and continuous learning. It will be accomplished by considering the essential procedures or sequence of dental hygiene activities. 2. When organizing curriculum elements, we should consider the continuity dimension of learning content. Continuity deals with the vertical manipulation or repetition of curriculum components. In other words, it accounts for the reappearance in the curriculum of certain major ideas or skills. Therefore, courses should be based on the level of the dental hygienist activities in order to ensure a continuity of learning experiences. 3. Dental hygienist curriculum must be organized in a way to integrate the logic of dental hygiene as a discipline with the process of dental hygiene performance. Integration refers to the linking of all types of knowledge and experiences contained within the curriculum design. It emphasizes horizontal relations among various content topics and themes involving all domains of knowledge recognized. Thus, courses of dental hygiene curriculum should be integrated to allow college students to obtain a unified view of knowledge and an in-depth meaning of the dental hygiene as a profession.

Objectives : The recognition rate for issues and improving resolution for the recuperation income expense claim policy was examined. Methods : 1,135 copies of survey have been sent to the group of people who have claimed the dental recuperation income expense to dental recuperation institutions in Daejeon, Chungcheong Do that are registered to the health insurance evaluation and estimation office as of the May 2010 and 207 surveys that were regarded to be sincere for answering were analyzed. Results : Majority of respondence were belonged to the dentist institutions with more than 5 years of claim experiences as well as 10~50% of claim rate. The recognition of medical fee evaluation guideline was normal level, and negative recognition was higher to the health center with daily charge policy compare to the dental hospital and university affiliated dental center with treatment charge policy, Highest opinion for inappropriateness of dentist with significance was found (p<0.05). The openness of evaluation cases are regarded to be discharged through the transparent evaluation and most of the opinions for insurance claim evaluation adjustment are within the both 'Do not understand the evaluation guideline and program error of disease category, code and program' with significance(p<0.05). The reaction after the evaluation adjustment was high in reflection on the claim process after examining the reason for the evaluation adjustment through the evaluation and estimation office and university affiliated dental institution and dental center was regarded to be most active and deputy reclaimment was seemed to be most actively discharge the objection registration task (p<0.05). The claim error improving resolution recognition was highly prioritized to the accurate charting for the disease title and treatment description, improving the setting of claim program, and most highly recognized by the university affiliated dental hospital/dental center and comparably low by health center(p<0.05). and although the most of the responds of treatment description and browsing the medical fee was positive, 50% of dentists disagreed the idea so that this was creating a significant discrepancy with other groups(p<0.05). Conclusions : From this research, the recognition of medical fee evaluation guideline for dental (university) hospital and dentists were negative and high adjustment experience was examined as lacking of evaluation guideline understanding and error of disease name, code and programs and deputy reclaimment, university affiliated dental hospital/dental center were most actively handle the objection registration tasks and dentists have objection on the treatment description and browsing the treatment fee so that if these indexes can be referred to implement into the recuperation income claim process, this can be regarded to be a opportunity to create mutual credibility between recuperation institution, treatment pensioner and the evaluation institutions.

Background: To promote and maintain oral health among adults, the relationship between oral health and obesity was examined, and the effects of oral health on obesity were investigated. Methods: A total of 4,270 Korean adults aged ≥20 years were selected as study subjects using raw data from the first year (2019) of the eighth period of the Korea National Health and Nutrition Examination Survey (KNHANES). Complex sample Rao-Scott chi-square test and complex sample logistic regression analysis were performed using PASW Statistics ver. 18.0. Results: The prevalence of abdominal obesity was 1.3 times higher subjects with poor oral health than in those with good perceived oral health and 1.3 times higher in subjects who did not receive dental checkups compared to those that did. The frequency of brushing of teeth was 1.2 times higher for subjects who reported brushing 2~3 times per day compared to those who reported brushing four or more times per day. The risk of being overweight was 1.3 times higher in subjects with one or more dental implants than in those with none. Conclusion: To build an integrated health program, it is thought that a preventive approach through self and expert oral health care, considering the age-specific characteristics of adults, is necessary for the intervention process used to build customized obesity prevention projects at the national level.
