Dental porcelain should have adequate strength and similar esthetics as natural teeth. Recently esthetics has become a high priority in clinical dentistry. Thus the evaluation of color stability of dental porcelain has become an important part in dental research. The purpose of this study was to evaluate the difference in color stability of 3 types of porcelain (Vintage, VMK 95, CERAMCO II). The porcelain were divided into groups by 2 types of treatment (Glazing or non-glazing and thermocycling or non-thermocycling). The porcelain wee dyed with methylene blue and distilled water, and then the color stability was evaluated with a spectrophotometer. The results were as follow ; 1. The color change of porcelain increased in the order of VMK 95, Vintage, CERAMCO II. But there was no significant difference. 2. The color change decreased in the glazing group compared to the non-glazing group(p<0.05). 3. The color change increased after thermocycling But there was no significant difference. 4. The color change according to dye method was significantly larger with methylene blue copared to distilled water(P<0.05).

PURPOSE: This study was done to identify effects of fatigue and postpartum depression on quality of life in early postpartum mothers. METHODS: The data were collected from 130 mothers at four general hospitals in J and M metropolitan cities. Instruments used to collect the data for the study were the Fatigue Scale developed by Pugh (1993); Postpartum Depression Scale developed by Cox, Holden & Sagovsky (1987), and the Quality of Life Scale developed by Hill, Aldag, Hekel, Riner, G., & Bloomfield (2006). RESULTS: Results showed that the mean for fatigue was 56.74, the mean for postpartum depression was 8.00+/-4.37 and mean for quality of life was 19.78. The quality of life variable showed statistically significant differences for the variable: age (F=3.20, p=.026). The relationship between fatigue and quality of life showed a significant negative correlation (r=-.44, p<.001). The relationship between postpartum depression and quality of life also showed a negative correlation (r=-.42, p<.001). The relationship between postpartum depression and fatigue showed a positive correlation (r=.59, p<.001). These factors explained 23% of the variance in quality of life. CONCLUSION: The results indicate that it is necessary to develop nursing intervention programs to improve quality of life in for early postpartum mothers.

The purpose of this study was to develop the CORE Program for sex offenders and to determine its effectiveness. The CORE Program was designed with an aim to achieve cognitive restructuring, improve the ability to empathize in interpersonal relationships, and enhance self-esteem and intimacy. We conducted this program over 48 sessions for 28 sex offenders. The effectiveness of the program was evaluated using the Interpersonal Responsiveness Index (IRI), Self-esteem Questionnaire (SEQ), UCLA Loneliness Scale (UCLALS), Coping Using Sex Inventory (CUSI), Rape Myth Acceptance Scale (RMAS), and Wilson's Sex Fantasy Questionnaire (WSFQ). The data were analyzed using paired t-tests. Our results showed no significant changes in the SEQ, UCLALS, and IRI scores after the treatment program. However, the scores for the CUSI, RMAS, and WSFQ significantly improved after this program. In this paper, we demonstrate the effectiveness of the CORE Program for sex offenders. We also discuss the limitations of our study and provide suggestions for future research. Our findings indicate that this treatment program should be provided to sex offenders for preventing recidivism.

PURPOSE: The purpose of this study was to determine the relationships of pain cognition, performance status, and hope with health-related quality of life. METHODS: Patients(n=149) with various cancer diagnoses completed the SF-36 standard Korean Version and the Herth Hope Index. The Perceived Meanings of Cancer Pain Inventory was used to measure the cognition dimension of pain, whereas the Brief Pain Inventory Korean version was used to represent the sensory dimension of pain. RESULTS: The patients in the pain group had significant differences in the three dimensions(loss, threat, spiritual awareness) of pain cognition. There were statistically significant negative correlations between the three dimensions(loss, threat, and spiritual awareness) of pain cognitions and SF-36 dimension, and the positive correlations between challenge dimension and SF-36 dimension. Hope had the positive correlation with SF-36 dimensions. CONCLUSION: Pain has a negative impact on health-related quality of life, especially on physical health. However, patients who ascribed more positive meaning to their pain, tended to have a higher quality of life. Therefore, nursing intervention to reinforce the positive aspects of pain cognition is to empower patients to create a sense of control and assume an active role in pain management and quality of life.

Purpose: This study used an exploratory sequential approach (mixed methods) design to explore essential meaning through comparing and analyzing the experiences of nursing students in virtual simulation practice and high fidelity simulation practice education in parallel. Methods: The study participants were 20 nursing students, and data were collected through focus group meetings from July 17 to August 5, 2020, and via online quantitative data from November 10 to November 15, 2020. The qualitative data were analyzed using Giorgi's phenomenological method, and the quantitative data were analyzed using descriptive statistics, the Mann-Whitney U test, Kruskal–Wallis H test analysis of variance and Spearman’s ρ correlation. Results: The comparison between the two simulation training experiences was shown in five contextual structures, as follows: (1) reflection of the clinical field, (2) thinking theorem vs. thinking expansion, (3) individual-centered learning vs. team-centered learning, (4) attitudes toward participating in practical training, (5) metacognition of personal competency as a prospective nurse, and (6) revisiting the method of practice training. There was a positive correlation between satisfaction with the practice and the clinical judgment ability of high fidelity simulation, which was statistically significant (r=.47, p=.036). Conclusion Comparing the experiences between virtual simulation practice training and high fidelity simulation practice training, which has increased in demand due to the Coronavirus Disease-2019 pandemic, is meaningful as it provides practical data for introspection and reflection on in-campus clinical education.

Purpose: Rapid changes have occurred in the educational environment of colleges since the outbreak of COVID-19. This study was conducted to determine the factors influencing college life adaptation for nursing students. Methods: The participants included 124 nursing students. A self-administered online questionnaire, available from March 30 to April 10, 2022, was used for data collection. The online questionnaires included COVID-19 stress, interpersonal relations, information literacy, and college life adaptation. Statistical analysis was performed using t-test, ANOVA, Pearson's correlation coefficient, and multiple regression analysis. Results: The average score for adapting to college life was 3.32±0.58. Significant differences in college life adaptation were found based on the number of exercise days per week (F=3.62, p=.015), regular daily routine (t=-3.41, p<.001), amount of sleep (t=-3.61, p<.001), sleep quality (t=-3.90, p<.001), and diagnostic self evaluation (F=19.55, p<.001). Factors that influenced college life adaptation included interpersonal relations (β=.36, p<.001), diagnostic self evaluation (good) (β=.48, p<.001), diagnostic self evaluation (fair) (β=.38, p=.005), and COVID-19 stress (β=-.11, p=.027), which explained 38.0% of the college life adaptation. Conclusion Development of a program that integrates interpersonal relations, diagnostic self- evaluation, and COVID-19 stress for nursing students is recommended to improve college life adaptation.

PURPOSE: Cytolethal distending toxin (CDT) considered as a key factor of localized aggressive periodontitis, endocarditis, meningitis, and osteomyelitis is composed of five open reading frames (ORFs). Among of them, the individual role of CdtA and CdtC is not clear; several reports presents that CDT is an AB2 toxin and they enters the host cell via clathrin-coated pits or through the interaction with GM3 ganglioside. So, CdtA, CdtC, or both seem to be required for the delivery of the CdtB protein into the host cell. Moreover, recombinant CDT was suggested as good vaccine material and antibody against CDT can be used for neutralization or for a detection kit. MATERIALS AND METHODS: We constructed the pET28a-cdtC plasmid from Aggregatibacter actinomycetemcomitans Y4 by genomic DNA PCR and expressed in BL21 (DE3) Escherichia coli system. We obtained the antibody against the recombinant CdtC in mice system. Using the anti-CdtC antibody, we test the native CdtC detection by ELISA and Western Blotting and confirm the expression time of native CdtC protein during the growth phase of A. actinomycetemcomitans. RESULTS: In this study we reconstructed CdtC subunit of A. actinomycetemcomitans Y4 and generated the anti CdtC antibody against recombinant CdtC subunit expressed in E. coli system. Our anti CdtC antibody can be interacting with recombinant CdtC and native CDT in ELISA and Western system. Also, CDT holotoxin existed at 24h but not at 48h meaning that CDT holotoxin was assembled at specific time during the bacterial growth. CONCLUSION: In conclusion, we thought that our anti CdtC antibody could be used mucosal adjuvant or detection kit development, because it could interact with native CDT holotoxin.
