The purpose of this study was to investigate learning motivation, learning attitude and self-directed learning in collaborative learning. For this study, sampled 31 dental hygiene students, period of 1 semester, Dept of Dental Hygiene, H University. statistical verification conducted pared t- test through SPSS 18.0. The results of this study are as follows: 1. Students were increased positive change in learning motivation(concentration and self confidence) after collaborative learning (p<0.05). 2. Students were increased positive change in learning attention(preparation and self Participation) after collaborative learning (p<0.05). 3. Students were increased positive change in self-directed learning and self-efficacy after collaborative learning (p<0.05). 4. collaborative learning satisfaction was higher in learning process (self-directed learning, communication) and learning effect (Utilization in the clinical situation, Medical thinking and judgment, Disease diagnostic capabilities) more than direct instruction (p<0.05). In conclusion, collaborative learning for dental hygiene students education was more effective in learning motivation, learning attitude and self-directed learning. therefore this study suggest that collaborative learning contribute to enhancing learning effect throught self-directed learning.

This study has reached the conclusion as follows, being done through a questionnaire method for 250 parents with children under 7, hospitalized in the pediatric associations, daycare centers and pediatric dental clinics located in Daegu and Gyeongbuk from July 10th, 2013 to August 5th. 1. It was relatively higher appeared the average (range : 1~4) of the oral health behavior of the mothers about their children as 28.62 points. Among the practice questions of the ten, it is the highest this statement : “I exchange my kid's toothbrush regularly.” and followed this one : “I let my child brush his teeth before going to sleep.” 2. It was highly meaningful statistically for the oral health behavior about children by general features in the case of having a high level of education and getting an occupation(p<.05). and also as high as their monthly income possible (p<.01). 3. The comparison result of the children's oral health practice by the birth and the early childhood caries factors for relationship is highly meaningful as having many children (p<.05) and in the case of the mother's recognition about the early childhood caries or no having the early childhood caries and the dental caries (p<.01). 4. The effective factors of the maternal health practice to her child include like this : the childhood caries recognition, monthly income, the numbers of children and the mother's age, moreover a mother with the recognition of the childhood caries, high monthly incomes and a younger one who has many children does high frequency as to the oral health practices (p<.05, 01, 001). According to these results, in order to improve the children's oral health, we need to develop our national level's oral health education program and regular enforcement for the mothers of the infant or the pregnant women.

This study was carried out in order to examine the influence of oral health education upon subjective perception and oral health impact profile by figuring out OHIP (Oral Health Impact Profile) according to the difference in subjective perception by school year and to the oral health perception, targeting 217 students in freshman, junior, and senior who are attending M university in Jeollanam- do Province from September to December in 2012. Thus, the following conclusions were obtained. 1. As for the difference in subjective perception by school year, the significant difference wasn't shown in health perception. However, the significant difference was indicated in oral health perception, oral health knowledge, oral health attitude, and oral health practice. 2. As for items on functional limitation out of OHIP, the significant difference was shown according to oral health perception in 6 items among totally 9 items. 3. As for items on physical pain out of OHIP, the significant difference was shown according to oral health perception in 6 items among totally 9 items. 4. As for items on psychological distress out of OHIP, the significant difference was shown according to oral health perception in all of 5 items among totally 5 items. 5. As for items on physical, psychological, and social abilities out of OHIP, the significant difference was shown according to oral health perception in 15 items among totally 26 items. Synthesizing the above results, the higher in school year and the more increase in credits completed for major subjects lead to having influence upon OHIP (Oral Health Impact Profile). In light of this, the increase in an opportunity of oral health education for people is considered to lead to likely bringing finally about improvement in quality of life through OHIP.

The purpose of this study is to apply an oral health education program o certain high school students, and to evaluate the improvement of its knowledge and behavior, the promotion of oral health, and its satisfaction with the education through in-depth interviews, thus using all of those results as the basic data for the future oral health education to be required in high school students in Korea. For the objectives, the oral health education program was administered among 1st year students of M high school in Nowon-gu, Seoul, for the period from 28 May 2010 to 19 October 2010, followed by the interviews with five students selected among those involved in the program all the way. First, the knowledge level on oral health education has been improved significantly as a whole. Second, even with the improvement of oral health behaviors through the education, there was hardly significant on such behaviors as regular checkups and dental floss. Third, the effect of S -PHP index looked to be gradually decreased over the education sessions, with the change of brushing administration. Fourth, overall the students has been satisfied with the program educator, but not for the education methods. Taken together the those results, for the oral health promotion in high school students the education should be to be emphasized on the behavior-change objectives rather than on the knowledge-based objectives. In addition, to prevent the recurrence to the old bad behaviors there must be required the ongoing oral health education as well as the development of educational methods attracting the attention. In considering of their oral growth, particularly, such a education content as plaque removal or prophylaxis needs to be included in the further advanced education. It can be said that this study has its significance, in providing its results and implications could be used as the basic data for further developing systematic materials on the oral health education in the high school students.

In this study, Journal of Dental Hygiene system for the first time published papers published in the Journal of Dental Hygiene research methods, statistical analysis on the type and frequency of status to identify and analyze trends, Journal of the overall research identifying the current situation and future direction of to address this research was conducted. Thus the search of the paper changes, and recent research by identifying trends continue in future to establish the identity of the Journal of Dental Hygiene Research out to find ways to develop the knowledge base for establishing and may have important significance. This study published in the Journal of Dental Hygiene study were included in the study. Journal of the Society of Dental Hygiene is published since 1999 was conducted in this study to investigate research trends 1 1999 1 (first issue) from 14 in 2012 to No. 4 published papers were finally selected. Released in the process of data collection as much as possible try to collect all of the Society between 2001 and 2002, but have not been able to find Journal of the data. Journal of Research on the final missing data in the collection, except for a total of 185 research papers were finally selected. 1. Looking at the two methods of data collection questions District 163 service (70.9%) The most common oral examination 25 service (10.9%), other 12 service (5.2%), 11 interviews law service (4.8%), experiment 7 service (3.0 %), literature by 6 (2.6%), observation (2.6 percent). 2. Except experimental study by target 209 research papers on the dental hygienist look at a paper target 46 service (22.0%) and was most common in patients admitted to the dental hygiene students and one paper each side 28 (13.4%), target 19 public service (9.1%), 17 college students target service (8.1%), guardian side target 16 (7.7%). 3. The number of authors 2, 70 (37.8%) was the most common, one of 69 (37.3%), 3 of the 36 (19.5%), 4 of the 6 (3.2%), five or more persons 4 (2.2%) in order.

Oral health research in behavioral science subjects classified 80 (43.2%) and was most common application Dental Hygiene 58 (31.4%), other 22 (11.9%), basic dental hygiene 11 (5.9%), dental hygiene education 8 (4.3%), dental hygiene management 6 (3.2 percent). 6. The references cited in the paper, an average number of 16.6 References 11.6 domestic and foreign reference number showed a level of 4.7, the average level of self-citations in the Journal of the low level of 0.25, respectively. The effort by this study to analyze the paper included in the Journal of the Korean academy of dental hygiene to grasp research trends in the field of dental hygiene is expected to be of some use for the determination of the right directions of dental hygiene research in the future.

The study aims to examine the relationship between sterilization and disinfection of the instruments frequently used by dental hygienists and assistants and to determine the optimal shchedule for sterilization. This survey was conducted 133 dental hygienists and dental assistants in dental clinics located in Jeollanam-do. The data were collected by using the self-administered survey method. Collected data were analyzed by using the SPSS Window ver.12.0 (SPSS Inc, Kor) statistics program. 1. 60.7% of dental hygienists and dental assistants had experiences in infection control education. As for the age group, 73.9% of dental hygienists and dental assistants in their twenties experienced infection control education, which was higher than the figure of 46.9% of dental hygienists and dental assistants over the age of 30. As for the job classification, 75.5% of dental hygienists had experiences with the education, which was higher than that of dental assistants. 2. As for the dental items or instruments, 90.4% of dental handpieces, 97.8% of ultrasonic scalers, 76.1% of resin instruments, 100% of dental standard instruments, 80.6% of crown removers, 78.5% of dental injection syringe, 73.1% of condensers, 83.7% of reusable dental impression trays, 100% of periodontal hand instruments and 97% of implant surgical instruments were being sterilized and disinfected. 3. As for the sterilization and disinfection of dental treatment instruments, 23.8% of dental handpieces, 50.0% of ultrasonic scalers, 31.4% of resin instruments, 81.5% of dental standard instruments, 43.5% of crown removers, 26.4% of dental injection syringe, 38.8% of condensers, 72.6% of reusable dental impression trays, 86.7% of periodontal hand instruments and 100% of implant surgical instruments were being sterilized and disinfected for ‘every a patient’. 4. Also, 83.0% responded that the 'infection control of dental hygienists and dental assistants' was the most important element for improving the infection control. The sterilization and disinfection of semi-critical dental items should be reinforced, and the infection control should be educated to the dental health-care personnel on a regular basis.
