To investigate the perceptions and attitudes of dental hygienists toward radiation safety management in Korea. A total of 800 dental hygienists were randomly selected for an anonymous survey, and 203 of them participated. The questionnaire items included the following: sex, career period, type of installed radiographic equipment, recognition of the diagnostic reference level (DRL), participation in radiation safety education, and attitudes toward radiation protection for both patients and dental hygienists. The participants were divided into two groups according to their years of experience (< 10 years versus ≥ 10 years). The difference between the groups was investigated according to frequency distribution. Fisher's exact test or Pearson's chi-square (𝛘²) test was used as appropriate. A regression analysis was performed to investigate the impact of wearing a thyroid collar for personnel protection during patient radiation exposure. The types of installed radiographic equipment included panoramic radiography (96.1%), cephalometric radiography (76.9%), intraoral radiography (72.9%), and cone-beam computed tomography (69.5%). Significant differences were observed in the learning pathway for the DRL (Fisher's exact test, p < 0.05), satisfaction with radiation safety education (Pearson's 𝛘² test = 5.3975, Pr = 0.02), and use of personnel radiation monitoring systems (Pearson's 𝛘² test = 18.1233, Pr = 0.000) between the groups. Significant differences were also observed in personnel protection using a thyroid collar and patient protection during panoramic radiography (odds ratio = 14.2). Dental hygienists with more than 10 years of experience were more satisfied with radiation safety education and more interested in radiation monitoring. Considering career experience, customized, continuous, and effective radiation safety management education should be provided.

Purpose: To find objective validity of minimal acupuncture using a modified guide tube as a method to verify the effect of acupuncture. Methods: Subjects of this study were participants of a randomized clinical trial which was practiced to verify the effect of acupuncture on postmenopausal hot flash. There were 2 arms of treatment, one's for active acupuncture group(AG) with manipulation and De qi, the other's for minimal acupuncture group(MG) using a modified guide tube which was designed to give minimal stimulation to the patient. After 8 weeks' treatment followed by 4 weeks' observation, participants were asked to fill in self-report forms on their education, previous experiences of acupuncture, original idea on the efficacy of acupuncture and recognition of blinding. Results: 19 participants of 26 in AG and 19 of 26 in MG completed the self-report form. There was no difference between AG and MG in their education(p=0.5976, Fisher exact test) and previous experiences of acupuncture(p=0.9999, Fisher exact test). In their original ideas on the efficacy of acupuncture, most of AG and MG respondents have been thought that acupuncture is very effective or quite effective, and there was no difference between 2 groups(p=0.5065). 16 of 19 in AG and 14 of 19 in MG believed that they underwent more effective way, there was no statistical difference between 2 groups(p=0.6928, Fisher exact test). Participants believed in undergoing more effective way not because they recognized treatment method, but they were satisfied with the effectiveness of treatment retrospectively. Conclusion: As the result of this study, these authors suggest that minimal acupuncture using a modified guide tube is acceptable as a method to verify the effect of acupuncture in acupuncture-familiar Korean culture. Also further studies on the stimulation-specific effect of minimal acupuncture are demanded.

Objectives : This study identified the effects of the acupuncture associated with successful cessation at a smoking-cessation clinic of public health center in an urban area. Methods : The subjects of this study were 1121 patients to the smoking cessation clinic of the Anjung Public Healthcare Center in Pyeongtaek, from June 1, 2007 to December 31, 2008. The 123 patients of them were treated by the auricular acupuncture. The experimental group were treated by the acupuncture, and the control only participated in the smoking-cessation clinic program. The data were analysed by SPSS(version 17.0). Chi-square analysis were conducted to see the different of effects between experimental and control group. Also, to find out the factors that affect the success of smoking cessation, logistic regression and Fisher's exact test were done. Results & Conculusions : 1. As the result of the analysis, it showed that 73.2% of the experimental were able to quit smoking for 4 weeks and 6months. 2. Logistic regression and Fisher's exact test showed that number of Cigarette per day, Nicotine Dependence, CO figure(p=.004<.01), and Number of Acupuncture(p=.000<.001) were the factors that affect the successful smoking cessation. 3. The smoking cessation were more likely to success as patients have lower CO figure(B=-.074), more number of the acupuncture(B=1.718). The more number of acupuncture increased 1 time, the more smoking cessation success did 5.576 times(e$^{(1.718{\times}x)$=e$^{(1.718{\times}1)$ = 5.576). 4. As the result of the analysis between experimental and control group, the success rate have the significance difference(p=.000<.001). 73.2% of the experimental were able to quit smoking, but 45.1% of the control did.

Objective : We performed this study to investigate whether the use of closed-suction drainage following microvascular decompression (MVD) causes cerebrospinal fluid (CSF) leakage. Methods : Between 2004 and 2011, a total of 157 patients with neurovascular compression were treated with MVD. MVD was performed for hemifacial spasm in 150 (95.5%) cases and for trigeminal neuralgia in 7 (4.5%) cases. The mean age of the patients was $49.8{\pm}9.6$ years (range, 20-69). Dural substitutes were used in 44 (28.0%) patients. Ninety-two patients (58.6%) were underwent a 4-5 cm craniotomy using drainage (drainage group), and 65 (41.4%) did a small 2-2.5 cm retromastoid craniectomy without closed-suction drainage (no-drainage group). Results : Eleven (7.0%) patients experienced CSF leakage following MVD based on the criteria of this study; all of these patients were in the drainage group. In the unadjusted analyses, the incidence of CSF leakage was significantly related with the use of closed-suction drainage following MVD (12.0% in the drainage group vs. 0% in the no-drainage group, respectively; p=0.003; Fisher's exact test). Those who received dural substitutes and the elderly (cut-off value=60 years) exhibited a tendency to develop CSF leakage (p=0.075 and p=0.090, respectively; Fisher's exact test). In the multivariate analysis, only the use of closed-suction drainage was significantly and independently associated with the development of CSF leakage following MVD (odds ratio=9.900; 95% confidence interval, 1.418 to infinity; p=0.017). Conclusion : The use of closed-suction drainage following MVD appears to be related to the development of CSF leakage.

The purpose of this study was to investigate the effects of mindfulness meditation programs based on stress management on the perceived stress, self-control, self-esteem and satisfaction with life scale in nursing college students. A quasi-experimental study with a non-equivalent control group pretest-posttest design was used. Participants consisted of an experimental group(n=18) and a control group(n=22). The experimental group received the mindfulness meditation program for 60 minutes a week for 13 sessions. Data were analyzed using descriptive statistics, ${\chi}^2-test$, Fisher's exact test, t-test, Mann-Whitney U test. The results showed there were significant decrease for perceived stress(t=-9.43, p=.025) and improved self-esteem(t=1.98, p=.038) in the experimental compared to group control group. These findings indicate that mindfulness meditation programs is effective to psychological well-being in nursing college students. Therefore this program needs to be considered as a nursing curriculum for students.
