The objective of the paper is to analyze the extent to which elementary school students acquired, perceived, and practiced oral health knowledge provided by an elementary school-based oral health clinic (SBOHC). It is respectively investigated by gender and year of school. The paper will be relevant for developing specified oral health programs in elementary SBOHCs. By choosing three elementary schools that operate SBOHC in the school district of Daejeon Metropolitan City from April 11 to April 30, 2013, a self-administered questionnaire was given out to be answered directly by 350 students in the 4th, 5th, and 6th grades and their responses were collected. Of the collected responses, 326 responses were explored by using the SPSS 12.0. Those students' scores of oral health knowledge are found to be statistically meaningful for school year, not for gender. In them are included correct tooth brushing time, dental caries symptoms, gum disease symptoms, and correct tooth brushing method. Change in tooth brushing method after oral health education showed the statistically meaningful difference for gender and school year. In conclusion, every SBOHC should develop a variety of specified educational programs that depend on gender and grade in each elementary school.

This study aimed to qualitative analyze the cusp variation pattern of the mandibular second premolars using a three-dimensional virtual models, and to analyze the left-right bilateral symmetry with a quantitative analysis of the tooth surface area according to the cusp variation. 127 virtual mandibular second premolars were prepared and individual absolute/relative cusp area, total crown area and groove form were analyzed using RapidForm2004(INUS technology INC, Seoul, Korea). Independent t-test, Kruskal-Wallis test and chi-square were performed. As a result, the groove form showed high bilateral symmetry between the left and right sides. Based on the left side of groove form, the bilateral symmetry was 100.0% for the U pattern, and 73.7% for the H patterned, and 78.9% for the Y pattern(p<.001). The finding could be as a meaningful reference for manufacturing CAD/CAM dental prostheses, and it is expected that further studies will be conducted on more samples including the mandibular second premolar immediately after eruption.

Purpose: This descriptive study investigated the relationship between death awareness and life ethics awareness, according to life stress, among students in the department of paramedics. Methods: General characteristics were identified using means and frequency, and the differences between the two military models were analyzed using the χ²-test and t-test by dividing them into lower and higher groups based on the mean life stress score (99.76 points). Results: Those with high life stress had higher death awareness than those with low life stress at 114.11 points. In contrast, those with low life ethics experienced more severe life stress with a score of 145.61 points (t=-2.609, p=.010)(t=-2.953, p=.003). The death recognition attitude and bioethics according to the degree of living stress-showed a significant correlation between the low and high groups (r=.188, p=.043) (r=.201, p=.042). Conclusion: Paramedic students require education on how to cope with life stress. However, access to education is limited to people living in modern times. As a potential solution to this problem, observing videos on the Internet is recommended. Moreover, we suggest accessing Internet and smart phone applications for advertising/educational purposes.

The development of teaching models to strengthen practical education and actively participate in the classes of students is now required in recent education situations. This study examined the participation and satisfaction level of students' classes after applying a teaching model-integrated hospital and school laboratory (named L2L). A total of 33 students who took the subject of a clinical microbiology experiments were involved in this study. Each group representative participating in a pre-class field exercise in the hospital microbiology laboratory was asked to conduct the experiment. After applying the L2L teaching models, the academic self-efficacy ($2.87{\pm}0.58{\rightarrow}3.38{\pm}0.55$), class participation ($2.60{\pm}0.92{\rightarrow}3.62{\pm}0.78$), and class satisfaction ($2.48{\pm}1.01{\rightarrow}3.85{\pm}0.87$) increased significantly (P<0.05). This means that pre-class field exercises created interest in the student's class and boosted self-confidence, leading to increased participation and satisfaction for the class. In conclusion, the L2L teaching model is an effective teaching method to enhance the practical training for preliminary clinical laboratory technologists.

This study was conducted to check the effect of parenting attitudes on oral health behavior on lower grade elementary school students where oral care habits are formed. The subjects of the study were 366 students in the lower grades of elementary school, and the research tools used self-written questionnaires that were modified and supplemented to suit this purpose. Parenting attitudes of parents and lower-grade oral health behavior of elementary school students showed significant amounts of correlation, especially affectionate, autonomous and reasonable parenting attitudes were highly correlated with oral health behaviors(p<0.01). A multiple regression analysis to identify the factors affecting oral health behavior showed that parental attitudes also had a significant effect on the child variables(p<0.01). Therefore, since parenting attitudes are related to children's oral health behaviors, it is believed that measures should be taken to promote oral health education that can be improved by combining them.

Let me introduce a teaching method to improve practice capacity in dental laboratary work. I applied theories of layers of modeling and reflection constituting cognitive apprenticeship and peer tutoring to my class. At internet uploading a file showing a practice procedure a week before the class of a course, I let students preview it. During the class I demonstrated the practice procedure in front of students. A superior student and an inferior student paired according to the previous practice grade and a feedback between a peer tutor and a peer tutee was activated. Late in the class, a student self-evaluated his own practice result and had a check of a professor. Finally he compared his own practice result with that in the file uploaded at internet and reflected. This teaching method led to improvement in students' satisfaction and efficiency of learning.

The purpose of this study was to examine the quality of life of high schoolers related to oral health. The subjects in this study were 287 high school students, on whom a survey was conducted. After the collected data were analyzed, the following findings were given: 1. As for self-perceived oral health state, 34.8 percent of the high schoolers investigated found themselves to be in a good oral health, and 65.2 percent didn't. In regard to concern for oral health, 15.7 percent showed a lot of interest, and 52.6 percent were a little interested. 31.7 percent had no interest in that. 2. Out of the oral health impact profile (OHIP) areas, they scored highest on the area of physical pain(2.24) and lowest on the area of social disadvantage(1.35). The overall oral health impact profile was 1.66. 3. Concerning relationship between general characteristics and the OHIP areas, the high school boys got significantly higher scores on the area of social disadvantage, and those who had ever visited dentist's offices scored statistically significantly higher on the areas of physical pain and mental insecurity. 4. Regarding connections between concern for oral health and the OHIP areas, those who were very interested in oral health got statistically significantly higher scores on every area. 5. As to the correlation among the OHIP areas, there was a statistically significantly positive correlation among all the areas.

The purpose of this study was to examine the views of dental hygiene students about the possible countermeasure of domestic hospitals for the opening of the medical market. The subjects in this study were 269 dental hygiene sophomores, juniors and seniors at two different colleges in the region of Busan. The findings of the study were as follows: The opening of the medical market and views of possible countermove, whether they agreed to that or not made a statistically significant difference to their opinions on the necessity of customer-oriented marketing strategy(p=0.023), analysis of foreign medical markets/attempt to make inroads into the markets(p<0.000) and the improvement of the quality of medical services/the diversification of the services(p=0.025). As to an intention of going to a foreign hospital, they had a statistically significantly different intention about whether to go to a foreign hospital regardless of medical bills(p<0.000), whether to consult a doctor in a foreign hospital after going to a domestic hospital first (p<0.000), whether to consider the distance between their houses and a foreign hospital(p=0.05) and whether to take considerations on the assistance of an interpreter(p=0.023). In regard to preference for foreign hospitals, American hospitals ranked first(41.9), followed by Australian hospitals(19.9) and Canadian ones(14.2).

Objectives: The purpose of this study was to determine if self-rated oral health differed according to self-reported oral health behaviors in Korean adolescents. Methods: The raw data of 'The 6th Youth Health Behavior Online Survey' carried out by the Korea Center for Disease Control and Prevention were analysed. Independent t-test, one-way ANOVA, and Logistic regression analysis were used to assess the relationships between oral health behaviors and self-rated oral health (n=73,238). Results:Oral health behaviors had stronger influence on daily toothbrushing habits. In particular, participants who brushed their teeth in the morning and participants who brushed their teeth more than 3 times a day were more likely to have good self-rated oral (P<0.001). Conclusions: Korean adolescents with high self-rated oral health reported practicing good oral health behaviors. These results highlight the need for the further practicable oral health education programs.

Purpose: The purpose of this study was to assess the association of vocational interest and personality with temporomandibular disorders (TMD). Methods: Four hundred and fourteen college students in Gyeonggi-do completed Vocational Preference Inventory L form and a questionnaire and collected data were analyzed by R program. Results: The percentage of subjects who responded that they had at least one contributing factor for TMD was significantly different among 27 two-letter Holland codes (p<0.05). The two-letter Holland codes of which the first-letter was social (S) (S artistic [A], S investigative [I], S realistic [R], S conventional [C], S enterprising [E]) or C (CE, CS, CA, CI) had tendency of having the relatively higher prevalence of symptoms and contributing factors for TMD. Among 6 one-letter Holland codes, the prevalence of a symptom of frequent fatigue in the jaw and a habit of gum chewing showed the significant difference (p<0.05). E code seemed to have lower prevalence of a symptom of frequent fatigue in the jaw than other codes. S code appeared to use chewing gum more frequently than other codes. High scorers on emotional instability showed the significantly higher prevalence of TMD symptoms (p<0.05) and contributing factors for TMD (p<0.001) than low scorers. Furthermore, high scorers on emotional instability had significantly higher mean scales of the number of positive answers of TMD symptoms (p<0.01) and of contributing factors for TMD (p<0.001) than low scorers. Conclusions: Symptoms and contributing factors for TMD were related to emotional instability. Vocational Preference Inventory L form might be utilized in assessing emotional factors of persons with TMD symptoms.
