The purpose of this study was to evaluate suppression of Streptococcus mutans(S. mutans) colonization by long-term xylitol consumption among pregnant women who can easily get bad oral hygiene status during pregnancy and breast feeding. Participants were voluntarily recruited for a pregnant women's oral health prevention program, classified into two groups(a control and a xylitol group), and then followed for 18 months. Stimulated whole saliva was collected in the afternoon(1:00-3:00 p.m.) at baseline, 6 months, 12months, and 18 months. Information regarding oral health behavior(tooth brushing frequency and regular dental visits) was obtained via a questionnaire. S. mutans counts of the xylitol group decreased considerably between baseline and the re-examinations at 6, 12, and 18 months. Although the S. mutans counts decreased for all time points compared to baseline in the control group, these differences did not reach significance except 18 months. Regular chewing of xylitol gum over a long period may lead to decrease the colony counts of S. mutans.

While many social work studies has focused on the development of practice intervention and demonstration of the efficacy, little attention has been given to the way how the results can be disseminated and utilized in practice area. But attempts to bridge the research-practice gap empathize importance of dissemination and utilization including knowledge utilization, innovation diffusion, information dissemination, program replication, and technology transfer etc. In this recognition, this study that focused on the process after development of program tried to search and analyze the real disseminating process and utilization state with applying Growing-up Skills Program(GUSP) developed and disseminated by this researcher. For the purpose, theories and models for program diffusion were reviewed, and dissemination & utilization of GUSP was analyzed on the 'Herie & Martin's model' with retrospective perspectives. Through this tracer study, these were confirmed or founded as problems of GUSP in disseminating process : lack of specific strategy for the dissemination ; unplanned coping due to little preparation ; and unclear and insufficient understanding of the target system in the beginning stage of dissemination. And followings are suggested for the improvement of social work program dissemination & utilization in the field: to conduct diffusion process on the basis of a proper model; to consider integrative relationship between D&D and dissemination & utilization ; to endeavor for collecting feed back from the field ; and to reinforce social work education and study related to innovation diffusion. These results showed importance of dissemination & utilization in social work and utility of GUSP despite of several limitations. More concerns of dissemination & utilization are needed for the integration of research and practice in Korean social work.

In this experiment, eleven volunteers were followed up for 15 months after the injection of botulinum toxin type A on right and left masseter muscles. The measurement of masseter muscle atrophy for each volunteer was performed by CT(computed tomography) three times: before the injection, three and fifteen months after the injection. The thickness and area of muscle were measured in three positions which are 10 (position 1), 20 (position 2), and 40 mm (position 3) above the inferior border of mandible(the injection site was nearest the position 1). The thickness of masster muscle was decreased in all three positions three months after the injection, but no significant change was observed fifteen months after the injection. On the other hand, the area of masster muscle was decreased in all three positions three months after the injection. Furthermore, the area was decreased significantly in positions 1 and 2, but not in position 3 fifteen months after the injection. As a result, toxin is still in effect even fifteen months after the injection. Finally, the present study shows that the measurement of muscle area provides more precise informations than that of muscle thickness does.

The subject of investigation was 13,828 people who took periodical medical examiner in some health examination centers two times in 2009 and 2011 so as to analyze changes of borderline group, disease group for 4 diseases(hypertension, diabetes, liver disease, hyperlipemia) and health behavior of some medical examiner. For the contents of investigation, drinking and smoking habit was investigated as a general characteristic of subjects. For the items of health examination, there were SBP, DBP, AST, ALT, GGT, Glucose, Total Cholesterol and Triglyceride. The main results are as follows. In comparison with the starting year of research, drinking and smoking rate of the final year was reduced respectively by 1.6% and 1.4%. And, borderline group by examination items, hypertension was reduced by 2.2% from 62.0% to 59.8% in the final year in comparison with the starting year of investigation, And, fasting blood glucose was 17.1%, hyperlipemia was 6.6%, LFT was 2.0% for the reduction. In disease group, hypertension was reduced by 0.6% from 6.7% to 6.1%. And, fast blood glucose was 1.9%, hyperlipemia was 4.2%, LFT was 1.3% for reduction. Borderline group showed more reduction in comparison with disease group in all of items. The above results showed borderline group showed more reduction of manifestation rate than disease group in all of 4 diseases. Therefore, it's expected that disease group will show reduction in the future. But, it's necessary to study on future's changes through the continuous management and tracing observation.

In this study, we performed the carotid artery ultrasound targeting 140 subjects who have conducted to evaluate the changes in intima-media thickness(IMT) and plaque correlated with the presence or absence of a hematological test of the carotid artery. Considering that the IMT thickness more than 1mm is abnormal based on the carotid artery ultrasound to assess the presence or absence of plaque, and examined the correlation by classifying the blood lipid value and the fasting blood glucose level through the serum test. Consequently, the fasting blood glucose level is being analyzed as independent predictors of causing dental plaque(p=0.033), cut off value was determined as 126 mg/dL(sensitivity 56.25%, specificity 68.38%) in ROC curve analysis. Furthermore, the odds ratio appeared 1.01 times the value in the Logistic regression. Therefore, it seemed that the necessity to prospective studies in a number of subjects are considered, and also taking into account a number of blood test values along with the sonography of the carotid artery as a valuable part for effective primary prevention and follow-up observation of the cardiac and brain vascular disease is highly recommended.

Objectives: This study aimed to evaluate the change in weight and heart rate associated with the use of phentermine through meta-analysis based on the published literatures. Methods: Eight electronic databases, PubMed, EMBASE, Cochrane library, and five domestic databases were used to search the literature. Randomized controlled trials that evaluated the change in weight and heart rate with the use of phentermine compared with placebo were included in this study. The fixed-effect model weighted by the Mantel-Haenszel method was used in the meta-analysis, and the random-effects model was used when heterogeneity was present. Results: We included 12 studies comprising 677 patients. The change in weight observed with the use of phentermine (SMD = -1.37, 95% CI: -1.55, -1.19) was statistically significant compared with that observed with placebo. As per the subgroup analysis results, the change in weight by publication year, country, phentermine dosage, follow-up check was not heterogeneous. The change in heart rate observed with the use of phentermine (SMD = 0.64, 95% CI: 0.35, 0.92) was significant compared with that observed with placebo. Conclusions: Weight loss and increased heart rate were confirmed in phentermine compared with placebo.

This cohort study aimed to identify the effects of daily PM10 exposure on the hospital admission of patients with respiratory diseases, during the nine-year period (2002-2010), in Seoul, Korea. The research subjects were 13,974 patients who had been hospitalized with respiratory diseases, including chronic obstructive pulmonary disease (COPD), asthma, and pneumonia. During the follow-up period, an increase of 10 ug/m3 in PM10 under the threshold of 50 ug/m3 of PM10 led to hospital admission in 1.38% of the age group younger than 15 years, 1.62% in those 65 years or older, 2.87% in patients 75 years or older and in 1.50% of pneumonia patients, 1.51% of COPD patients, and 1.55% of pneumonia and asthma patients. Under the threshold of 80 ug/m3 of PM10, there was a 3.71% increase in new patients admitted in the age group 65 years or older and 4.25% in those at least 75 years old. Our study found that high PM10 was associated with increased risk of admission of respiratory patients, especially in the elderly. People who already have a respiratory disease should refrain from exposure to particulate matter when there is a high concentration of PM10, especially older patients.

The aim of this study is to evaluate the effect of noise-filtering earplugs on the hearing ability of dentists wearing them during noise-induced dental procedures. Pure tone audiometry and distortion product otoacoustic emission (DPOAE) tests were conducted at the initial visit and 1 year later to evaluate the hearing ability of the participants. As a result of the study, the pure tone average of the group wearing earplugs decreased significantly compared to the group not wearing earplugs, indicating an improvement in hearing. However, the signal-to-noise ratio of the DPOAE tests did not show a significant difference. These findings suggest that noise-filtering earplugs may have some effectiveness in preventing hearing loss. However, since the 1-year observation period may not be adequate to identify changes in hearing, a follow-up study with an extended follow-up period is necessary.
