This study was carried out to present the basic data needed for the establishment of management measures for the subjective symptoms of the musculoskeletal system according to the working postures of dental hygienists. The questionnaires, in which the answers were filled in directly by individuals, were distributed to those who accepted the offer and are in general hospitals, dental hospitals, private hospitals and so on during a month period between October 9th to November 2nd in 2012. The subjects were 80 people in general hospitals, 110 in dental hospitals and 60 in private hospitals which is a total of 250 people. Of these, 233 were retrieved and surveys with inappropriate or insincere responses were excluded. Hence, 230 surveys were used for analysis. Among these, those who responded that they have had musculoskeletal system disorder due to exercise or accident were excluded. For the data analysis, Stata(version 12.0 StataCorp LP College Ststion, TX, USA) program was used. 1. Looking at the subjective symptoms of pain according to bodily parts, the subjects' inadequate postures during examination or assisting examination were related to the parts that caused pain. In particular, when the neck is bent during examination, all the body parts investigated except the legs were shown to cause pain. 2. As a result of analyzing 49 people's management effect according to working posture among 147 people with pain, more than 90% answered that getting massaged was effective, more than 80% said physical therapy and herbal remedy, and exercise was less effective than other therapies. Management of pain for preventing work related pain is needed and for this, massage, physical therapy, exercise and so on have shown effectiveness. However, in order to reduce economic and temporal loss, an exercise education program that can prevent and manage pain should be developed to teach those experiencing pain in different working fields.

The purpose of this study was to examine the oral health behaviors and recognition of college students and any possible differences in those aspects according to their general characteristics in an attempt to provide some information on the oral health promotion of college students. The subjects in this study were 292 students who were selected by convenience sampling from colleges in Joenbuk. They included 186 male students and 106 female students. A self-administered survey was conducted to gather data. 1. As for oral health concern, the largest group of the college students(35.6%) replied they were a little concerned about oral health. Regarding oral health knowledge, the biggest group(69.2%) had an average level of oral health knowledge. As to self-rated oral health status, the greatest group(43.2%) found themselves to be in normal oral health. Concerning the importance of oral health, the largest group(70.2%) considered oral health to be important. 2. In regard to the relationship between general characteristics and limitation of activities caused by oral diseases, 41.8 percent answered they faced difficulties due to oral diseases, and 17.5 percent of those respondents replied their studies were affected by oral diseases. By gender and academic year, 50 percent of the female students and the largest group of the freshmen(47.3%) answered their daily lives were affected by oral diseases(p<0.05). In the case of the respondents whose studies were affected by oral diseases, the female students(22.6%) outnumbered the male students, and the rate of the freshmen(23.6%) was highest. There were statistically significant differences in that regard according to gender and academic year(p<0.05). 3. As to dental treatment experience over the last year, 58.2 percent of the college students didn't receive any dental treatment. By monthly mean allowances, the largest number of the respondents who received dental treatment over the last year got 510,000 thousand won or more for pocket money(70.0%), and the differences between them and the others were statistically significant(p<0.05). The most common reason that the respondents who needed to receive dental treatment over the last year actually didn't do it was time constraints(46.4%), followed by lack of concern(31.75%) and financial status (21.3%). 4. In terms of oral health education experience, 45.2 percent had ever received oral health education, and the female students(52.8%) had more experience to do that. As many as 72.3 percent of the smokers received no dental health education, and there were statistically significant differences in that aspect according to gender and smoking(p<0.05). There were differences among the college students in oral health awareness and behavior according to their general characteristics. Oral health education should be provided in consideration of their characteristics.

The purpose of this study was to examine the satisfaction level of adult patients with dental services provided by dental clinics in some regions in an effort to provide information on the improvement of dental environments and services. This is a field suryey involved 350adult patients treted in dental outpatient clinics in Jeon-Ra-Nam-Do between March 2012 and June 2012. 1. As for the characteristics of hospital use involving motivation of using particular dental institutions, the largest group(37.2%) decided to do that on their own. The most common type of treatment that they received was periodontal treatment(30.8%). 2. Regarding the level of dental service satisfaction, they gave the highest marks of 40.4 to the item "dental hygienists look neat and clean." They gave 3.72 to the item about general satisfaction with dentists, and there were significant differences according to marital status, academic background and occupation. They gave 3.72 to the item as to general satisfaction with dental hygienists, and the female patients gave significantly higher marks to that than the male patients. 3. Concerning general satisfaction with internal environments, they gave 3.86, and there were significant differences according to occupation only. In terms of general satisfaction with treatment process, they gave 3.72, and there were significant differences according to age and occupation. The patients who were in their 30s and who had the unspecified occupations were most satisfied(4.00). 4. As to general satisfaction with dental expenses, they gave 3.47, and there were significant differences according to age, academic background, occupation and income. The respondents who were aged between 30 and 40, who received college or higher education, who were government employees and who earned an income of three million won or more expressed the highest satisfaction. The findings of the study show that there were differences among dental patients in satisfaction level according to their general characteristics. Dental hospitals and clinics must try to improve their dental services in consideration of the differences of patients caused by their own characteristics.

The objective of this study is to determine the influence of sleep disorder on the population of Streptococcus mutans in the oral cavity. Total 158 college students were divided into GSHG(Good sleep habits group) and DSPG(Delayed sleep phase group) in accordance with their sleep habits, and also were classified into NSG(Normal sleep group) and SDG(Sleep disorder group) in accordance with the degree of daytime sleepiness. We conducted a survey about average sleep hours in weekends and weekdays, and daytime sleepiness index with ten volunteers of each GSHG and DSPG, and also 15 volunteers of each NSG and SDG. BY using selective medium, we compared the amount of salivation and the population of Streptococcus mutans in the oral cavity. In the study results, the average weekend sleep hours of DSPG(547.5±66.99) were significantly more than the ones of GSHG(452.8±49.07)(p<0.05) while the average weekend sleep hours of SDG(544.5±92.74) were significantly more than the ones of NSG(415±37.84)(p<0.05). In comparison of population of S. mutans, the average population of DSPG(11.6±2.78(107 CFU/ml)) was significantly more than the one of GSHG(6.7±2.75 (107 CFU/ml))(p<0.05). In case of salivation amount, there was no significance in the classification in accordance with sleep habits while the classification based on daytime sleepiness index showed significant difference in the amount of salivation between NSG(0.282±0.064 ml,) and SDG(0.228±0.058 ml)(p<0.05). In conclusion, it was found that college students' bad sleep habits increased the population of Streptococcus mutans in the oral cavity. We also found that college students who experienced daytime sleepiness had more population of Streptococcus mutans in the oral cavity and the amount of their salivation was also decreased compared to the students who had no experience of it.
