Purpose: The purpose of this study was to identify the relationship between critical thinking disposition and clinical competency of nursing students. Method : The sample consisted of 151 nursing students, who have ever had clinical practice. Data were collected by self reporting questionnaire for 13 days from April 18-30, 2005. The data were analyzed by descriptive statistics, t-test, ANOVA, Duncan test, Pearson Correlation Coefficient with SPSS Programs. Result : The result of this study were as follows : 1. The total mean score of critical thinking dispositions in the nursing students was moderately(3.50). There was a statistically significant difference in critical thinking disposition according to satisfaction with the nursing major(F=5.563, p=.005). 2. The total mean score of clinical competency in the nursing students was slightly high(3.37). There was a statistically significant difference in clinical competency according to adaptation with the nursing major(F=5.202, p=.007), satisfaction with clinical practice(F=3.172, p=.045). 3. A significant positive correlation between critical thinking disposition and clinical competency was founded(r= .421, p<.000). Conclusion : In conclusion, this study revealed that critical thinking disposition influences clinical competence. Therefore, the finding of this study may provide significant basic data for nursing education and nursing practice.

Purpose: This study aimed to evaluate the performance of Clinical Research Nurses (CRNs) and the importance of their roles at the Regional Clinical Trial Centers (RCTCs). Method: A questionnaire focused on the role of CRNs was crafted by a researcher and the content validity was verified by a panel of experts on clinical research. The subjects of this study were 91 CRNs and Clinical Research Coordinators (CRCs), who were Korean registered nurses working at nine RCTCs. 77 subjects yielded valid data were analyzed using descriptive analysis, the Mann-Whitney U test, Spearman's rank order correlation coefficient, and Kruskal-Wallis test. Results: The performance of CRNs and the recognition in the importance of their roles were statistically significant different in age, education, CRN careers, positions, employment status and the phase of clinical trial. The role of direct caregiver was performed most often by CRNs. The role of coordinator of care and research (pre-study) was considered the most important role but performed the least frequent. Conclusions: The role of CRNs can easily be differentiated from CRCs who are not registered nurses. The domains of CRNs should be clearly identified and established. Moreover, research should be carried out on CRN training programs to cultivate competence in CRNs.

Purpose: This study was conducted to identify the effect of verbal violence, clinical practice stress, and coping with stress on the major satisfaction in nursing students during clinical practice. Methods: A cross-sectional study was used. A survey was conducted from May 3 to May 10, 2022, on 200 nursing students who were in their junior and seneior years at two universities in Gyeongsangbuk-do. Descriptive statistics, frequency analysis, independent t-test, one-way ANOVA, Scheffé's test, Pearson correlation coefficient, and hierarchical regression analysis were employed to analyze the data. Results: Major satisfaction was found to be significantly negatively correlated with verbal violence (r=-.30, p<.001) and clinical practice stress (r=-.15, p=.032) and to be positively correlated with coping with stress (r=.24, p<.001). Their satisfaction with clinical practice (β=.29, p=.037), verbal violence (β=-.23, p<.001), coping with stress (β=.16, p=.015), religion (β=.14, p=.041), and clinical practice stress (β =-.13, p=.048) explained 19.3% of the variance in nursing students' major satisfaction during clinical practice. Conclusion: A verbal violence and coping with stress program for nursing students should be developed to increase nursing students' major satisfaction during clinical practice.

This article is a narrative review that discusses the recommended sample size requirements to design a pilot study to assess the reliability of a questionnaire. A list of various sample size tables that are based on the kappa agreement test, intra-class correlation test and Cronbach's alpha test has been compiled together. For all calculations, type I error (alpha) was set at a maximum value of 0.05, and power was set at a minimum value of 80.0%. For the kappa agreement test, intra-class correlation test, and Cronbach's alpha test, the recommended minimum sample size requirement based on the ideal effect sizes shall be at least 15, 22, and 24 subjects respectively. By making allowances for a non-response rate of 20.0%, a minimum sample size of 30 respondents will be sufficient to assess the reliability of the questionnaire. The clear guideline of minimum sample size requirement for the pilot study to assess the reliability of a questionnaire is discussed and this will ease researchers in preparation for the pilot study. This study provides justification for a minimum requirement of a sample size of 30 respondents specifically to test the reliability of a questionnaire.

Background: Quantitation of urine protein is important in dogs with chronic kidney disease. Various analyzers are used to measure urine protein-to-creatinine ratios (UPCR). Objectives: This study aimed to compare the UPCR obtained by three types of analyzers (automated wet chemistry analyzer, in-house dry chemistry analyzer, and dipstick reading device) and investigate whether the differences could affect clinical decision process. Methods: Urine samples were collected from 115 dogs. UPCR values were obtained using three analyzers. Bland-Altman and Passing Bablok tests were used to analyze agreement between the UPCR values. Urine samples were classified as normal or proteinuria based on the UPCR values obtained by each analyzer and concordance in the classification evaluated with Cohen's kappa coefficient. Results: Passing and Bablok regression showed that there were proportional as well as constant difference between UPCR values obtained by a dipstick reading device and those obtained by the other analyzers. The concordance in the classification of proteinuria was very high (κ = 0.82) between the automated wet chemistry analyzer and in-house dry chemistry analyzer, while the dipstick reading device showed moderate concordance with the automated wet chemistry analyzer (κ = 0.52) and in-house dry chemistry analyzer (κ = 0.53). Conclusions: Although the urine dipstick test is simple and a widely used point-of-care test, our results indicate that UPCR values obtained by the dipstick test are not appropriate for clinical use. Inter-instrumental variability may affect clinical decision process based on UPCR values and should be emphasized in veterinary practice.

After a health examination, abnormal patients were classified into two groups. One needs clinical treatment immediately, while the other one needs check-up in 2~3 month after for blood tests and preventive medical study. To discover the status and importance of the follow-up study in a health program, blood test upon health examination was compared to the test from the follow-up. We examined patients of ages from 20's to 70's. Among these patients, most of them were between 40's and 50's, and in male patients the follow-up test were more freguent than female. We examined blood obtained from January 2007 to December 2008. We analyzed and compared initial and the follow up blood test. Lipid profile, liver test, thyroid function tests (TFTs), glucose fasting, and HbA1c were examined from the blood tests. We also surveyed their distribution and status. The value of the follow up blood tests was significantly decreased with the most striking differences in lipid profiles and liver test. Follow up study is able to improve life style of patients through doctor's advice in a health program. Therefore, we can conclude that the follow up blood test is also quite critical.

This study was conducted to develop a simulation-based education program for respiratory infectious disease and to identify the effects of clinical competency, self-leadership and critical thinking after applying to nursing students. A non-equivalent pre-post test of quasi-experimental design was used. The study subjects were 30 students for the experimental group and 30 for the control group. Respiratory infectious disease simulation-based education was provided for 5 weeks. Data analysis was performed using SPSS WIN Ver 21.0 with Fisher's exact test, independent t-test, and paired t-test. Clinical competency, self-leadership, and critical thinking of the experimental group showed statistically significant differences in comparison with the control group. These study results proved that a simulation-based education program for respiratory infectious disease is effective in raising nursing students' clinical competency, self-leadership and critical thinking. Therefore, it is considered that simulation-based education should be provided to cultivate nursing problem-solving clinical competency, self-leadership or critical thinking by developing a scenario based on various clinical situations.

Purpose: The aims of this study were to evaluate the clinical characteristics of patients with altered sensation and/or pain, and to determine outcome predictors affecting persistent neuropathy. Methods: Patients who complained an altered sensation or pain following trigeminal nerve trauma were involved in this study. To determine outcome predictors affecting persistent neuropathy, the patients were divided into two groups; transient vs. persistent, and the clinical phenotypes are compared between groups. Data were analyzed with t-tests, chi-square, and multiple regression analyses with 95% confidence interval and p<0.05 significance level. Results: A total of 111 patients were included: 23 with transient and 88 persistent groups. The panoramic result and pin-prick test score were statistically different between the groups. Radiating symptoms after blunt and pinprick stimuli were also significantly different between groups. The results revealed that the presence of a neurologic lesion in the panoramic view result, reduced sensation in the pinprick test, and radiation in the pinprick test could affect the persistent group. Conclusions: The presence of a neurologic lesion in panoramic view result and reduced sensation and radiating symptoms in the pin prick test would be defining features of one of the main clinical features of persistent neuropathy. These features could serve as outcome predictors diagnosing the permanent nerve injury in trigeminal nerve.
