Objectives: The purpose of this study was to investigate tooth whitening maintenance efficacy of several dentifrices containing effective ingredients for tooth whitening. Methods: Hydroxyapatite specimens(HAPs) staining was done by using modified Stookey's methods. HAPs were treated with 2.9% hydrogen peroxide containing strip for whitening, and were shaken with several dentifrice slurry(dentifrice 1 : artificial saliva 2) for 30 minutes. The HAPs were finally dipped in staining solution for an hour. Shaking and dipping were repeated 4 times and lightness values were measured by colorimeter at each step. In clinical test, test 4 dentifrice and control dentifrice were evaluated by 21 subjects for 2 months after receiving institutional review board(IRB) approval. Organoleptic(vita shade guide) and instrumental(SHADEEYE-NCC) evaluation were performed for whiteness change of teeth. Statistical analysis was performed using repeated measures ANOVA, Tukey's post hoc test and ${\chi}^2$-test(p<0.05). Results: All dentifrices showed statistical significance in comparison with control dentifrice containing sodium fluoride and test 4 dentifrice containing sodium pyrophosphate, sodium metaphosphate, candelilla wax, and sodium fluoride showed statistical significance in comparison with other dentifrices by inhibiting staining in vitro(p<0.05). In clinical test, test 4 dentifrice showed better effects than control dentifrice in organoleptic and instrumental evaluation in tooth whitening maintenance efficacy(p<0.05). The awareness toward tooth whitening maintenance efficacy for 2 months use showed that test 4 dentifrice was much better than control dentifrice, but did not show statistically significant(p>0.05). Conclusions: Dentifrice containing sodium pyrophosphate, sodium metaphosphate, candelilla wax and sodium fluoride was more effective in keeping teeth white.

This study aimed to develop a peer-assisted learning (PAL) program for use in a core nursing skills education course and to investigate the effects of the education program on three key outcomes. A comparative study was conducted through the division of students of a core nursing skills education program into a treatment group and control group. After the programs, self-efficacy, confidence and satisfaction were compared between the groups. The comparison of these three factors indicated that the related scores were significantly higher in the treatment group receiving the education program with the PAL method than those of the control group receiving traditional education. We concluded that self-efficacy gave the nursing students the confidence that they could successfully perform their tasks and motivation to learn. Education programs using the PAL method are suggested as an effective method for the acquisition of skills among nursing students.

The purpose of this study is to develop cognitive behavioral therapy(CBT) to improve the parenting efficacy of married immigrant women, and verify its effectiveness. In the CBT of this study, behavioral technique was added to cognitive reconstruction based on cultural context in order to improve parenting efficacy. The study selected 28 married immigrant women, and randomly divided them into a CBT group(10), a general treatment group(8) and a control group(10). The CBT and the general treatment programs consisted of 10 sessions, approximately 2 hours in duration. The results of the study were as follows. 1) The level of parenting efficacy was improved significantly in the CBT and the general treatment group. 2) The level of negative automatic thoughts and dysfunctional parenting thoughts was significantly decreased only in the CBT group. 3) In the CBT and the general treatment group, the level of parenting stress and acculturative stress was decreased while the level of psychological well-being improved. On the other hand, the level of parent-adolescent communication was improved significantly only in the CBT group. 4) In comparison with the general treatment group, the CBT group showed higher parenting efficacy and lower automatic thoughts and dysfunctional parenting thoughts. This study has significance in its attempt to develop a parent training program to improve the parenting efficacy of married immigrant women by integrating behavioral modification and communication skills training focused on cognitive reconstruction of parenting-related negative thoughts and beliefs in application of the CBT paradigm.

PURPOSE: This study was conducted to determine the effect of dual-task training (based on the International Classification of Functioning, Disability, and Health; ICF) on walking ability and self-efficacy in individuals with chronic stroke. METHODS: 22 chronic stroke patients participated in this study. Participants were randomly allocated into either the single-task group (n=11) or the dual-task group (n=11). Both groups had physical training three a week for 4 weeks, and at a three-week follow-up. Outcome measures included the 10m walking test (10MWT), figure of 8 walk test (F8WT), dynamic gait index (DGI), and Self-efficacy scale. All data were analyzed using SPSS 18.0 for Windows. Between-group and within-group comparison were analyzed by using the Mann-Whitney U test and Wilcoxon singed-rank test respectively. RESULTS: In the dual-task group, the 10MWT, time and steps of F8WT, DGI, and self-efficacy showed significant differences between pre- and post-test (p<.05). The Changes between the pre- and post-test values of 10MWT (p<.05), DGI (p<.05), and self-efficacy scale (p<.05) showed significant differences between the dual-task group and single-task group. CONCLUSION: Participants reported improved walking ability and self-efficacy, suggesting that dual-task training holds promise in the rehabilitation of walking in chronic stroke patients. This study showed that ICF-based on a dual-task protocol contiributes to motor learning after chronic stroke.

This article examines gender differences in stress levels and coping strategies while using mobile phones. We constructed an e-mail survey to collect data from 1,000 adults in South Korea, and used latent means comparison and multi-group structural regression in structural equation modeling. It was determined that as compared to men, women were more vulnerable to stress. Regarding coping, women used all three coping strategies more equally than men, including active coping, expressive support seeking, and avoidance, whereas men mainly chose active coping; however, there were no significant gender differences in coping outcomes, and both women and men coped effectively by choosing their own personal strategies. We suggested how to reduce stress levels for women through enhancing their self-efficacy, as self-efficacy was shown to reduce stress levels specifically for women. Additionally, based on our findings, we proposed how both men and women could cope more effectively.
