2.Effect of bamboo salt on the caries activity of Streptococcus mutans.
Journal of Korean Academy of Oral Health 2016;40(4):238-243
OBJECTIVES: The purpose of this study was to evaluate the anti-caries activity of bamboo salt on Streptococcus mutans. METHODS: The pH of bamboo salt, bay salt, and NaCl were measured at concentrations of 1%, 3%, 5%, and 10%. At 3, 6, 9, 12, 18, and 24 h, the growth and acid production of S. mutans was measured using a spectrophotometer and pH meter, respectively. RESULTS: The growth of S. mutans remarkably reduced with the addition of 1% NaCl. Bamboo salt showed effective growth inhibition at concentrations higher than 3%. Bay salt showed effective growth inhibition at concentrations higher than 5% (P<0.01). At salt concentrations of 1%, the pH value of bacterial culture broth reduced to below 5.5 after 12 h. Bamboo salt and NaCl reduced acid production at concentrations higher than 3%. Moreover, bay salt decreased acid production at concentrations higher than 5%. CONCLUSIONS: These results showed that the bamboo salt inhibited growth and acid production of S. mutans. Thus, bamboo salt can be considered a useful material for the prevention of dental caries.

This was designed to identify the relationship of perceived stress, ways of coping, and stress response in student nurses. The subjects of this study were 320 student nurses from two universities and three junior colleges located in Seoul. The data were collected from November 28 to December 10, 1997 by a questionnaire survey method. The instruments for this study were the perceived stress scale developed by Levenstein(1993), ways of coping scale developed by Lazarus and Folkman(1984), and the stress response scale developed by Choi(1991). The data were analyzed by SAS program, using descriptive statistics, Pearson correlation coefficient, and ANOVA. The results are summarized as follows : 1. The mean score for the level of perceived stress was 2.55. 2. The mean score for the level of problem oriented coping was 1.61 and the mean score for the level of emotional oriented coping was 1.37. 3. The mean score for the level of stress response was 3.74. Stress was classified into nine factors and the order of scoring for the most frequent was; assignments(3.98), as a nurse(3.97), interpersonal relationship(3.88). 4. The relationship between perceived stress and stress response revealed a positive significant correlation(r=0.23, p=0.0001). 5. The relationship between emotional oriented coping and stress response revealed a positive significant correlation(r=0.22, p=0.0001). 6. The relationship between perceived stress and emotional oriented coping revealed a positive significant correlations(r=0.13, p=0.020). In conclusion, this study revealed that the level of perceived stress and ways of coping were important factors influencing the stress response of student nurses. Therefore, in consideration of perceived stress, ways of coping should be included in the development of a stress management program for student nurses. Further research with an expanded area and subjects is recommended.

7.Effect of metronome rates on the quality of bag-mask ventilationduringmetronome-guided30:2cardiopulmonary resuscitation: A randomized simulation study

BACKGROUND:Metronome guidance is a feasible and effective feedback technique to improve the quality of cardiopulmonary resuscitation (CPR). The rate of the metronome should be set between 100 to 120 ticks/minute and the speed of ventilation may have crucial effect on the quality of ventilation. We compared three different metronome rates (100, 110, 120 ticks/minute) to investigate its effect on the quality of ventilation during metronome-guided 30:2 CPR. METHODS:This is a prospective, randomized, crossover observational study using a RespiTrainer?r. To simulate 30 chest compressions, one investigator counted from 1 to 30 in cadence with the metronome rate (1 count for every 1 tick), and the participant performed 2 consecutive ventilations immediately following the counting of 30. Thirty physicians performed 5 sets of 2 consecutive (total 10) bag-mask ventilations for each metronome rate. Participants were instructed to squeeze the bag over 2 ticks (1.0 to 1.2 seconds depending on the rate of metronome) and deflate the bag over 2 ticks. The sequence of three different metronome rates was randomized. RESULTS:Mean tidal volume significantly decreased as the metronome rate was increased from 110 ticks/minute to 120 ticks/minute (343±84 mL vs. 294±90 mL, P=0.004). Peak airway pressure significantly increased as metronome rate increased from 100 ticks/minute to 110 ticks/minute (18.7 vs. 21.6 mmHg, P=0.006). CONCLUSION:In metronome-guided 30:2 CPR, a higher metronome rate may adversely affect the quality of bag-mask ventilations. In cases of cardiac arrest where adequate ventilation support is necessary, 100 ticks/minute may be better than 110 or 120 ticks/minute to deliver adequate tidal volume during audio tone guided 30:2 CPR.

OBJECTIVES: This study was designed to evaluate the relationship between quality of life (QOL) and psycho-socio-spiritual characteristics in male patients with alcohol dependence. METHODS: The sample consisted of 109 men with alcohol dependence defined by DSM-IV criteria. We assessed QOL by the WHO QOL assessment instrument-BREF (WHOQOL) and SmithKline Beecham QOL (SBQOL). Sociodemographic and alcohol related data were collected, and 7 questionnaires were administered: MAST, BDI, STAI, Drinker Inventory of Consequences (DrInC), Scale of Social Support (SSS), Religious Beliefs and Behaviors (RBB) and Spiritual Well-being Scale (SWBS). The correlations between each QOL score and other variables were examined, and stepwise multiple regression analysis was performed. RESULTS: The WHOQOL score positively correlated with education level, SSS (support) and RBB and negatively correlated with MAST, DrInC, BDI, STAI (trait) and SSS (conflict) scores. In stepwise regression analysis, the scores on the STAI and BDI contributed to the score on the WHOQOL. The SBQOL score correlated with the income level, and negatively correlated with BDI and STAI score. STAI score was a weak predictor of SBQOL score. CONCLUSION: The significant predictors of QOL in patients with alcohol dependence were psychological factors such as anxiety and depression.

OBJECTIVES: The purpose of this study was to examine the risk factors for periodontal diseases in Korean adults. METHODS: In this study, raw data obtained from the third year of the 5th National Health and Nutrition Examination Survey (2010-2012) were used. The data were collected from 5,513 Korean adults, aged > or =19 years. Multiple logistic regression analysis was performed to determine the odds ratio (OR) and confidence interval in order to ascertain the factors influencing periodontal diseases. RESULTS: Multiple logistic regression analysis was performed to verify the risk factors responsible for periodontal diseases in Korean adults in 2012. After all factors were adjusted for, the following were identified as the only risk factors for periodontal diseases: sex, age, income level, educational level, occupation, history of smoking and alcohol consumption, usual stress recognition level, diabetes, self-assessed oral health, and daily tooth brushing frequency. CONCLUSIONS: The results of this study revealed that sociodemographic characteristics, health behavior and status, self-assessed oral health, and oral health were the factors that affect periodontal diseases.

PURPOSE: The purpose of this study is to correlate the MR findings with clinical stage and clinical outcome, and to describe the evolutional changes of abnormal MR findings of transverse myelitis. MATERIALS AND METHODS: Medical records and spinal MR images of 23 patients with both clinical and radiological diagnosis of transverse myelitis were retrospectively reviewed. MR findings were correlated with clinical stages including interval between MR imaging and full development of clinical symptoms, and compared with the clinical outcome. RESULTS: Diffuse high signal intensity of the spinal cord on T2-weighted image with mild cord bulging (67%) and focal contrast enhancement of the cord (75%) were observed within the first four weeks after full development of clinical symptoms. The findings decreased in extent or vanished later than four weeks on either initial or follow-up MR images. Most patients with either cord atrophy or focal hemorrhagewithin the cord lesion had poor clinical outcome. CONCLUSION: The MR findings of transverse myelitis are nonspecific, which may be seen in a variety of diseases. Serial MRIs, especially follow up examination over at least one month after full development of clinical symptoms are useful in the diagnosis of transverse myelitis and predicting its prognosis.
