The subjects in this study were 117 parents and their children who resided in rural communities in the region of K. Methods: A survey was conducted with the consent of the parents from July 1 to 30, 2010. As for the survey on the children, the children who were in the lower grades were interviewed, and the upper graders filled out the questionnaires in person. A frequency analysis was carried out to find out the general characteristics of the parents and children, and x2-test was utilized to grasp the links between the general characteristics of the parents and the children`s oral health care. A SPSS WIN 12.0 program was employed to analyze all the collected data. The findings of the study were as follows: Result: 1. As a result of investigating the relationship of the occupation of the parents to the children`s regular dental checkup, the 71.8 percent of the entire children didn`t get a dental checkup on a regular basis. The biggest percentage of the children of the self-employed parents(100%) got a regular dental checkup, and 90.9 percent of the children of the government workers did that(p<.05). 2. As a result of checking the relationship of the occupation of the parents to the children`s dental-caries experiences, 39.3 percent of the whole children had no such experiences. The largest percentage of the children of the company employees(51.9%) had dental-caries experiences(p<.05). 3. Concerning the links between the academic credential of the parents and the children`s toothbrushing method, the biggest percentage of the children(40.2%) brushed their teeth up and down. The largest rate of the children whose parents were high-school graduates(41.5%) brushed their teeth in that way(p<.05). 4. Regarding the links between the toothbrushing time of the parents and the children`s view, 43.6 percent found their parents to take good care of their teeth to make them clean. 60 percent whose parents brushed their teeth after having breakfast and dinner took the best view(p<.001). 5.

Objective: The purpose of this study was to examine the relationship of the oral health behavior of oral prophylaxis clients and some residents in a community to their simplified oral environment index. Methods: The subjects in this study were 520 people who had their teeth cleaned in the oral prophylaxis practice lab in the department of dental hygiene at J health college. A survey was conducted from March 23 to June 3, 2010, by way of the self-reported questionnaire. The data materials are analyzed by general characteristics frequency and ratio, the relationship of oral health behavior and sex, age, scaling experience, simplified oral hygiene index x2 test analysis. Results: 1. Concerning links between gender and oral health behavior including daily toothbrushing frequency, the largest group of the respondents brushed their teeth three times a day(p<0.05). As to educational experiences on toothbrushing method and the use of oral hygiene supplies, the women had more educational experiences than the men(p<0.05). 2. Regarding connections between age and oral health behavior involving daily toothbrushing frequency, the largest number of the respondents brushed their teeth three times a day in every age group (p<0.001). As for educational experiences on toothbrushing method, those who were in their 50s and up(64.7%) learned about that, and they had more educational experiences with age(p<0.05). As for scaling experiences, the older respondents had their teeth scaled more often (p<0.001). 3. As to relationship between scaling experiences and oral health behavior, there were differences in toothbrushing frequency according to scaling experiences(p<0.05). Regarding educational experiences on toothbrushing method, those who had their teeth cleaned received more toothbrushing education(p<0.001). Concerning smoking, the nonsmokers had more experiences to get their teeth cleaned (p<0.001). 4. As for links between simplified oral environment index and oral health behavior including a time for toothbrushing, the respondents who did toothbrushing after every meal(80.4%) had good simplified oral environment indexes(p<0.05). 5. In regard to relationship between simplified oral environment index and oral health behavior, oral environment index had a positive correlation to the use of oral hygiene supplies(r=0.129**), toothbrushing time(r=0.116**) and educational experiences on toothbrushing method (r=0.099**). Smoking(r=-0.092**) had a negative correlation to that. Conclusion: The above-mentioned findings illustrate that oral health behavior is one of crucial factors to affect oral health status and oral environment care. Therefore oral prophylaxis practice lab visitors should receive education on the right toothbrushing method and the use of oral hygiene supplies to promote their oral health, and an incremental oral health care system that involves regular scaling should be introduced.

Objectives: The purpose of this study was to examine the satisfaction level of students with a job tour program and their major and their adaptation to their major in an effort to provide some information on student guidance and the improvement of dental hygiene education. Methods: The subjects in this study were 269 freshmen to find out their views of job tour and the relationship of their general characteristics and motivation of major choice to satisfaction level with their major and adaptation to the department, t-test and one-way ANOVA were carried out. And correlation analysis was made to look for connections among major satisfaction, major adaptation and satisfaction with job tour. Results: 1. As for the choice of major, the biggest group of 128 students (47.6%) made a decision on their own. 2. In regard to satisfaction level with their major, the freshmen got 3.55±0.67, and the sophomores got 3.36±0.66. There was a significant difference according to academic year(p<0.05). 3. Concerning the links between motivation for major choice and major satisfaction, the students who chose their major in consideration of their own aptitude or personality got the highest marks of 3.96±0.64(p<0.05). 4. As to satisfaction level with the job tour program, they were most satisfied with field trip(4.03±0.74). 5. Regarding the correlation among major satisfaction, major adaptation and satisfaction with the job tour program, there was a significant correlation among all the variables(p<0.01). Conclusions: The students who gave priority to their own aptitude and personality in choosing their major were more satisfied with their major and were better adapted to that. Therefore it`s required to consider how to boost the satisfaction level of students with their major and their adaptation to that.
