The purposes of this study were to identify acoustic parameters of connected speech and to contribute to acoustic analysis of dysphonic voice about patient's natural speech voice as well as sustained phonation of vowels. Acoustic parameters of sentences included LTAS (long-term average spectrum) mean and spectral slope over frequence ranges such as 0-4kHz, 0-6kHz, 0-8kHz, 0-12.5kHz as well as HNR. Acoustic parameters of the vowel 'a' included jitter, RAP, shimmer, NHR, and HNR. Based on 'G' of GRBAS for the severity of dysphonia, two experienced raters judged and classified as four groups including controls, mild, moderate and severe dysphonic group. Connected speech was two sentences extracted from 'stroll' passage. Parameters of the vowel and LTAS mean of the sentences were measured by CSL. The spectral slope of the sentences and HNR of the vowel and the sentences were measured by Praat. Data were statistically analyzed by Spearman correlation and Kruskal-Wallis test using SPSS 12.0. The results of this study are as follows: First, jitter, RAP, shimmer and NHR were significantly different between the groups. Second, for several frequencies, LTAS mean and spectral slope of the sentences were significantly different between the groups. Third, the HNR of the sentences were significantly different between the groups. Forth, there was a presence of correlation between HNR and NHR of the vowel and HNR of the sentences. Accordingly, this study concluded that LTAS, spectral slope, and HNR were predictive parameters of connected speech voice for dysphonic voice.

Background: Breast cancer is the leading cause of cancer-related deaths in women. Despite being associated with high morbidity and mortality, breast cancer is a disease that can be diagnosed and treated early. Materials and Methods: In this cross-sectional study of 321 women, data were collected by Questionnaire, Breast Cancer Risk Assessment Form and Champion's Health Belief Model Scale. Mann-Whitney U, Kruskal-Wallis, Chisquared tests and logistic regression were used in the statistical analysis. Results: It was found that only 2.2% of women have high and very high risk levels of breast cancer risk. There is a positive correlation between early diagnosis techniques and Health Belief Model Sub-Dimension scores which are sensibility, health motivation, BSE (Breast self-examination) self-efficient perception and negative correlation between mammography barrier score and BSE barrier score (p 0.05). When factors for not having BSE were examined, it was determined that the women who do not have information about breast cancer and the women who smoke have a higher risk of not having BSE. Conclusions: It is important to determine health beliefs and breast cancer risk levels of women to increase the frequency of early diagnosis. Women's health beliefs are thought to be a good guide for planning health education programs for nurses working in this area.

Purpose: This study was conducted to identify the relationships between the perceived and actual achievement on skill performance assessment and identify the relation to learning motivation factors. Methods: A total of 80 senior nursing students currently studying at a university participated in the study in 2015. Students completed a performance examination of 20 nursing skills at the end of their 7-week training period; their performance was rated using checklists. Students then completed a survey, which included questions about learning motivation and perceived achievement level. Data were analyzed by descriptive statistics, Pearson's correlation, and Kruskal-Wallis test. Results: There was a weak correlation between perceived and actual achievement. Intrinsic and extrinsic goal-orientation and self-efficacy in learning motivation factors was significantly correlated to perceived achievement. Perceived achievement and self-efficacy in middle quartile of actual achievement were higher than other upper- or lower-quartile group. Conclusion: The findings suggest that the motivation factors of learners should be taken into account to maximize academic achievement in nursing skills training. In addition, it should be considered a strategy to reduce the gap between perceived and actual achievement.

Purpose : The purpose of this study was to identify factors influencing the clinical competence of nursing students. Methods : The participants of this study were 209 nursing students who were in 3rd and 4th grade. The collected data were analyzed using one-way ANOVA, Kruskal-Wallis test, Mann-Whitney test, Pearson's correlation coefficients, and stepwise multiple regression. Results : Clinical competence had positive relationships with self-leadership (r=.59, p <.001) and resilience (r=.64, p <.001). Clinical competence was influenced by resilience (𝛽=.45), self-leadership (𝛽=.20), and grade (𝛽=.20), with an explanatory power of 44.9%. Conclusions : Based on these results, it is suggested that future nursing education should develop a curriculum that enhances students' personal abilities such as self-leadership and resilience, rather than only teaching knowledge and skills.

Objectives: The purpose of this study is to investigate the relationship between the degree of menopausal symptom and granulocyte/lymphocyte ratio, and heart rate varibility(HRV). Methods: From 11th April 2011 to 20th May 2011, a total 30 female subjects (age 41-60) was recruited. We evaluated the degree of menopausal symptoms by Kupperman' s index and measured subject's WBC differential count and HRV. The data were analyzed by Kruskal-Wallis test and Spearman correlation test using SPSS/PC ver 13.0 program. Results: 1. There was no statistically significant difference in granulocyte/lymphocyte ratio and HRV among 4 classified groups according to Kupperman's index.- Mild, Moderate, Severe and Urgent. 2. Granulocyte ratio and general symptom score(within Kupperman's index) significantly showed negative correlation coefficient(r=-0.499, p=0.005), and Lymphocyte ratio and general symptom score significantly showed positive correlation coefficient (r=0.374, p=0.042). 3. Granulocyte/lymphocyte ratio and HRV showed no significant correlation. Conclusions: There was no significant relation among the degree of menopausal symptoms and granulocyte/lymphocyte ratio, and HRV. But furthermore large scale study is required.
