This study was conducted targeting dental hygienists who take radiographs at dental institutions located in Daegu, Busan, Ulsan Metropolitan City and Kyungnam and Kyungbuk Province from July 18 to August 26 2011, in order to figure out factors to affect anxiety about being exposed to radiation. The findings of this study are as below. 1. The average score of anxiety about being exposed to radiation was 3.76±0.77, and the average score of radiation safety management behavior was 2.73±0.62. 2. There were meaningful differences in anxiety about being exposed to radiation, the current state of defense facilities (p<0.020), the intention of participating in safety management education (p<0.041), person in charge of handling radiation (p<0.010) and the need for safety management education (p<0.036). 3. In relation to radiation safety management behavior, there were significant differences in experience in safety management education (p<0.026), measurement of exposed dose (p<0.021) and the current state of defense facilities (p<0.008). 4. The level of defense facilities (p<0.015), the necessity for safety management education (p<0.031) and a radiographer (p<0.15) were found to be factors to affect anxiety about being exposed to radiation. In conclusion, these results imply that it is important to relieve anxiety of dental hygienists about radiation and improve radiation safety management behaviors, by enhancing the level of defense facilities of dental clinic's the radiography room and knowledge about radiation safety management through radiation safety management education.

In this study, the self-based survey was conducted with 225 dental staffs employed by the clinics, general hospitals and university hospitals in Busan and Gyeongsangnam -do. With SPSS Win. 19.0, frequency analysis, descriptive statistics, cross-tabulations, and multiple regression analysis were performed on the collected data. The results were as follows: 1. In frequency analysis of interest in the infection control, analysis factor of respondents in dental hospitals is 58.2 percent, higher than the dental clinics 2. The order in which the average of the practice of dental practitioners appear: sterilization & disinfection, personal hygiene, personal protective methods, asepsis, medical waste management. 3. Influence was investigated that high interest of co-workers or high interest of dentist or training of dental infection or high patient needs personal hygiene to personal hygiene of sub-area dental infection control practice 4. Influence was investigated that not being around cleaners or training of dental infection to personal protection methods of sub-area dental infection control practice. 5. Influence was investigated that high interest of co-workers or high interest of dentist to asepsis of sub-area dental infection control practice. 6. Influence was investigated that working in dental hospital or high interest of dentist to sterilization & disinfection of sub-area dental infection control practice. Putting above results together, we can confirm that ongoing commitment and perceptions about infection control of dental office are changing, and recognition and practice of infection control are going on well in dental hospitals employing many doctors and staffs. Therefore, we conclude that constant attention and training are required in dental clinics, and non-continuous interest and research are performed for further promotion and development.

The purpose of this study was to evaluate the actual state college students' behavior about the use of oral hygiene devices and to collect the baseline data for developing appropriate educational objectives to improve oral health. The subjects in this study 103 in province S university students' from september 2 to september 22, 2011. For the data analysis, an SPSS WIN 12.0 program was used and its signification level was 0.05. 1. To sex and age according to the practice application of oral hygiene auxiliary supplies distinction, there were significant difference that dental floss, interdental brush (p<0.05). 2. Regarding the motivation of using those oral hygiene devices 56.3% that it was because of recommendation by dental hospital. Negative answers 54.9% that it was because no selection guidance. 3. The affecting factors on the oral health state was gargle the solution, explained 7.2% (β=-0.265, p<0.05). The finding of this study, to increase the use of oral hygiene auxiliary supplies to people of the appropriate selection and correct usage of oral hygiene auxiliary supplies. To improve the oral health status effectively, informations and materials should be provide to dentist, dental hygienists and people.

This study was conducted in order to survey and compare adaptation to college life between vocational and general high school graduates among college students of health‐related majors and to provide materials for guiding vocational high school graduates’ adaptation to college life and high school students’ future career. The subjects of this study were freshmen and sophomores of some two ‐year colleges having healthrelated departments in the J Area, and data were collected through a survey from the 19th to 24th of September, 2011 using a self‐administered questionnaire. A total of 445 questionnaires were used in analysis. Data were analyzed empirically at significance level p<.05, p<.01 and p<.001 and SPSS Ver.18.0 was used. The major results of this study were as follows. 1. With regard to difference in adaptation to college life, general high school graduates were somewhat higher than vocational high school ones in academic adaptation and satisfaction with college life. 2. When adaptation to college life was compared between male and female students, male students except some of them showed higher adaptation to college life than female ones. In both types of high school graduates, male students were higher than female ones in academic adaptation, emotional adaptation, and satisfaction with college life. This may be partially because more than half of the male students had returned after completing their military service, but this needs to be studied further. 3. When adaptation to college life was compared according to school year, among vocational high school graduates, satisfaction with college life was higher in freshmen than in sophomores, but among general high school graduates, only emotional adaptation was higher in freshmen than in sophomores. The difference was relatively large in emotional adaptation and satisfaction with college life probably because study grows more difficult in the 2nd year due to the characteristics of health‐related departments and, as a result, vocational high school graduates’ satisfaction goes down in the 2nd year compared to that in the 1st year. In case of general high school graduates, their emotional adaptation was high in the 1st year but went down with advancing school year. These results suggest that, despite difference between them, both vocational and general high school graduates feel difficulty in study with advancing school year. As this study included only freshmen and sophomores sampled from two‐year colleges, however, more precise research may be necessary including 3rd‐year students. 4. When adaptation to college life was compared according to graduation year, among vocational high school graduates, those graduated earlier than 2010 or before showed the highest adaptation level in academic adaptation, emotional adaptation and satisfaction with college life domain but not in social adaptation, and those graduated in 2011 showed the second highest adaptation, and those graduated in 2010 showed the lowest adaptation. Among general high school graduates, those graduated earlier than 2010 showed the highest level of adaptation to college life in all the domains, those graduated in 2011 showed the second highest level, and those graduated in 2010 showed the lowest adaptation to college life. That is, without difference between vocational and general high school graduates, students who had graduated from the high school long ago, namely, late learners and students who had returned after the military service were most excellent in adaptation to college life, and those graduated in 2011, namely, freshmen were also good at adaptation. Those who had graduated in 2010, most of whom were supposed to be sophomores, showed the lowest adaptation. These results, similar to those according to school year, suggest that the curriculums of two‐year colleges should be more flexible and that further cause analysis is necessary in future research. From the results of this study as presented above, it was found that adaptation to college life was not different between vocational and general high school graduates but it was significantly different between male and female students, according to school year, and according to graduation year for the reasons such as the inclusion of male students who had returned after completing the military service, and more specific cause analysis is required for the reasons. Based on these results, we suggest future research to get objective materials for guiding vocational high school graduates studying health‐related majors and to develop research tools for broadening cause analysis to college students in four‐year colleges and universities.
