This study was conducted to identify the educational need of pregnant women, and to evaluate the effect of the 2-hour childbirth class provided by researchers. The subjects were composed of 183 pregnant women who participated voluntarily in the 2-hour childbirth class, and the data were collected by self reporting structured questionnaire designed by researchers. The data were analyzed with descriptive statistics, paired t test, and McNemar test by SPSS pc program. The results were as follows ; 1. Mean age of th subjects was 27 and most subjects graduated from the high school and the college. 80.3% of the subjects had nuclear family. 82.5% of the subjects were full time housewives. 2. 85.8% of the subjects were ipara. Though 71.6% of the subjects might have antepartal care in the clinic, 67.2% of the subjects had no chance to participate in the childbirth class before this study. 3. Subject's health and lifestyle, especially related to eating habits, were changed in the antepartum period. We found that the pregnancy affected positively on health and lifestyle of the women. Over 75% of the subjects became to understand the progress of labor, breath methods during the labor, and perineal exercise. Most subjects changed to think that they could control their body more actively and positively during the labor after participating in the childbirth class. 93.4% answered that 'childbirth class was necessary and important'. Most subjects wanted to be taught the contents, such as postpartum care, breast feeding, and infant care in the childbirth class. In conclusion, pregnant women to attend the childbirth educational program with their husband, and the 2-hour childbirth class provided by the researchers very effective in many aspects. Therefore we anticipated that the childbirth class on basis of pregnant women's needs will contribute to improvement of pregnant women's health and well-being during the labor.

Background: This research evaluated the effectiveness of an online education model in teaching breast self-examination to university staff and students. Materials and Methods: 1,679 women participated in a breast self-examination online training program. Breast self-examination knowledge evaluation forms developed by Maurer (1997) were used in the research and were evaluated on a 100 point scale. Paired t-test and McNemar's Test statistics were employed. Results: The participants scored an average of 46.5 (14.0%) on knowledge on breast self-examination before training, but 77.4 (11.0%) one month after education and 76.7 (9.52%) after six months. There was a clear significant difference between these knowledge levels (p<0.05). Similarly, while the rate for systematic practice of breast self-examination among women was 30.8% before training it increased to 47.8% afterwards. Again the difference was significant (p<0.05). Conclusions: Online education is an effective method for teaching breast self-examination to women.

Purpose: The purpose of this study was to determine the effects of an environmental enrichment program on barrier, benefit, confidence, and compliance of breast self-examination in women at 3 months after instruction. Methods: Nonequivalent control group pretest-posttest design was conducted among 62 healthy women. Data were collected through the self-reported questionnaires from December 2008 to March 2009. Women were assigned to one of two treatment groups: (a) no-support of environmental enrichment with the instruction control group; (b) the support of environmental enrichment with the instruction experimental group. All women received the same instruction on breast self-examination once a week for two weeks. Data were analyzed with paired t-test, McNemar test and ANCOVAs of controlling for age run using SPSS/WIN 17.0. Results: The experimental group was significantly lower than control group on perceived barrier (F=5.91, p=.02) and higher than control group on compliance of breast self-examination (F=4.57, p=.04) after environmental enrichment program. However the environmental enrichment program did not make significant differences on benefit (F=0.01, p=.91) and confidence (F=0.77, p=.38). Conclusion: Findings suggest that the environmental enrichment should be needed to support women's breast self-examination and expanded for compliance of breast self-examination to promote the secondary prevention of women breast cancer.

Purpose: The purpose of this study was to investigate hemato-oncology patients' discomfort and bleeding in relation to the bedrest time after bone marrow examination. Methods: A descriptive correlational study was conducted. The data were collected using self- report questionnaire from total of 131 patients who underwent bone marrow examination from January 2017 to September 2017. Data were analyzed with descriptive statistics, Wilcoxon Signed-rank test, McNemar's test and logistic regression. Results: The level of discomfort after 4 hours of bedrest was significantly higher when compared to 2 hours of bedrest(p<.001). The occurrence of bleeding after 2 hours of bedrest was significantly higher than 4 hours of bedrest(p<.001), however the degree of bleeding was slight. No bleeding occurred in 84% of the patients after 2 hours of bedrest. Conclusion: The results of this study demonstrated that shortening the bed rest time after bone marrow examination was helpful in improving the patient's well-being. Bedrest time could be shortened according to the site of bone marrow examination and patient's condition.

Purpose: The purpose of this study was to identify changes in the experience rate and level of symptoms of visual display terminal syndrome in college students attending online classes during the COVID-19 pandemic. Methods: Data were collected from February 22 to June 8, 2021 at three measurement points. A total of 117 college students were administered a visual display terminal syndrome survey just before online classes (T1), one month after the start of online classes (T2), and three months after the start of online classes (T3). The collected data were analyzed by frequency and percentage, paired t-test, McNemar test, and repeated measures analysis of variance using the IBM SPSS 25.0 program. Results: The intensity of college students' visual display terminal syndrome during online classes increased at T2 and T3 compared to T1. The rate of experiencing back discomfort or pain increased abruptly at T2 compared to T1. The intensity of college students' eye related symptoms and skin related symptoms increased at T2 and T3 compared to T1, while the intensity of college students' psychological symptoms, general body discomfort, and musculoskeletal symptoms increased at T3 compared to T1. Conclusion: The results of this study suggest that self-care programs are needed to prevent visual display terminal syndrome in college students who are in long-term online classes.

Objectives: The aim of this study was to perform a clinical and radiographic analysis of endodontically treated teeth (ETT) restored with cast metal posts (CMPs) or prefabricated glass fiber posts (GFPs) and crowns. Materials and Methods: Fifty ETT were restored with 25 CMPs and 25 GFPs at a private dental clinic between 2001 and 2016. The restorations consisted of 12 all-ceramic crowns, 31 metal-ceramic crowns, and 7 composite resin crowns. Demographic data, type of teeth, type of post-and-core system, time of placement, crown restorations, the number of proximal contacts, the type of antagonist, and reports of any complications after post-and-core placement were recorded for each patient. Assessments were performed at baseline (radiographic) and follow-up (radiographic and clinical). Data were analyzed by the McNemar test, the Pearson χ² test, and Kaplan-Meier survival curves (α = 0.05). The mean follow-up was 67.6 months. Results: No significant difference was observed for any of the radiographic parameters when the baseline and final radiographs were compared. In the clinical evaluation, anatomical form (p = 0.009) and occlusion (p = 0.001) showed significant differences according to the type of crown restoration; specifically, metal-ceramic and all-ceramic crowns outperformed composite resin crowns. Conclusions: CMPs and GFPs showed favorable results for restoring ETT after 6 years of follow-up. All-ceramic and metal-ceramic crowns showed higher survival rates and better clinical outcomes.

Diplophonia is generally defined as the perception of more than one fundamental frequency component in a voice. Its perceptual aspect has traditionally been used to evaluate diplophonia because the perceptions can be easily evaluated, but there are limitations in the validity of the reliability of the intra- and inter-raters, examination situation, and variation of voice sample. Therefore, the purpose of this study is to confirm the reliability and accuracy of auditory perceptual evaluation by comparing non-invasive indirect assessment methods (sound waveform and EGG analysis), and to identify their usefulness with diplophonia. A total of 28 diplophonic voices and 39 non-periodic voices were assessed. Three raters assessed the diplophonia by performing an auditory perception evaluation and identifying the quasi-periodic perturbations of the acoustic waveform and EGG. Among the three discrimination methods, intra- and inter-rater reliability, sensitivity, specificity, accuracy, positive likelihood ratio, and negative likelihood ratio were examined, and the McNemar test was performed to compare the discriminant agreement. The accuracy of the auditory perceptual evaluation (86.57%) was not significantly different from that of sound waveform acoustic (88.06%), but it was significantly different from that of EGG (83.33%). The reading time (6.02 s) for the auditory perceptual evaluation was significantly different from that for sound waveform analysis (30.15 s) and EGG analysis (16.41 s). In the discrimination of diplophonia, auditory perceptual evaluation has sufficient reliability and accuracy as compared to sound waveform and EGG. Since immediate feedback is possible, auditory perceptual evaluation is more convenient. Therefore, it can continue to be used as a tool to discriminate diplophonia in clinical practice.
