For the measurement of mass flow rate at a wide range of operation conditions, it is required that the critical nozzle gas different diameters, since the mass flow rate through the critical nozzle depends on the nozzle supply conditions and the nozzle throat diameter. In the present study, both computational and experimental investigations are performed to explore the variable critical nozzle. Computational work using the 2-dimensional, axisymmetric, compressible Navier-Stokes equations are carried out to simulate the gas flow through variable critical nozzle. In experimnet, a cylinder with several different diameters is inserted into the critical nozzle to vary the nozzle throat diameter. Computational results are compared with the experimented ones. The computed results are in close agreement with experiment. It is found that the displacement and momentum thickness of variable critical nozzle are given as a function of Reynolds numbers. The discharge coefficient of the variable critical nozzle is predicted using an empirical equation.

Purpose: This study was done to investigate the relationship between critical thinking disposition and clinical competence among nurses in general hospitals. Methods: This study was a descriptive-correlational study with a convenience sample of 560 nurses from 5 general hospitals. The data were collected by self-administered questionnaires. Critical thinking disposition was measured using the Critical Thinking Disposition Scale for Nursing Students. Clinical competence was measured using the Standardized Nurse Performance Appraisal Tool. Results: The mean score for critical thinking disposition and clinical competence was 3.37 and 4.10 respectively on a 5 point scale. A statistically significant correlation was found between critical thinking disposition and clinical competence. A regression model explained 72.8% of clinical competence. Prudence is the most significant predictor of clinical competence ($R^2=.728$). Conclusion: Study findings suggest that nurses with a higher level of critical thinking disposition would have a higher level of clinical competence. Furthermore, prudence might be the most important predictor of clinical competence. In order to strengthen clinical competence in nurses, the development and enhancement of critical thinking should be emphasized at the college level and nurses should be encouraged to make a clinical decision with greater prudence.

Objectives : The purpose of this study to investigate the Critical Thinking disposition in Nursing College students and related to ability of basic nursing science. Methods : Data were collected from 36 students who were students belong to one of province University. The instrument used in this study was California Critical Thinking Disposition Inventory(CCTDI) by Facione & Facione. The instrument was composed of 7 sub-items, truth-seeking, analyticity, systematicity, open-mindness, critical thinking, self-confidence, inquisitiveness, and maturity. The data were analyzed by descriptive statistics, t-test, ANOVA, Pearson Correlations with SPSS 12.0. Results : The result of this study were as follow; The average of total score in critical thinking disposition was 44.8, which means middle level(below 40: low, above 50: high level). Maturity was the highest while open-mindness was the lowest with an average score 5.01. There was significant difference between critical thinking and basic nursing science grade while there was no difference between age, gender, and religion. There was strongly relation between critical thinking disposition and basic nursing science(F=2.84, p=.01). Conclusion : According to the results of this study, nursing curriculum should be considered critical thinking disposition.

The purpose of this study was to examine the effects of internet-use Anatomy class, as one of the Flipped learning method, on critical thinking disposition. The class for this study was conducted from March 1 to April 10, 2018. The study involved a total of 180 people in the first year of a University located in C province. Data collection was carried out before and after the Flipped learning method application. Frequency analysis, Paired t-test, Pearson correlation, and Regression analysis were used for the analysis. According to the analysis, 28.3% of men and 71.1% of women and before applying the program analysis of correlation between Flipped learning perception and critical thinking disposition showed a significant correlation between confidence(sub-component of critical thinking) only (p<.005). Comparing the scores of critical thinking before and after the program, it was found that Truth seeking (p<.001), Open-mindness (p<.005), Confidence (p<.001), Systematicity (p<.005), Analyticity (p<.001), and Inquisitiveness (p<.001) scores had increased significantly except Maturity (p>.005). And the regression analysis of Flipped learning method applying influence on critical thinking disposition were significantly affected (p<.001). Based on the results of this study, it was possible to determine that Flipped learning method had a positive effect on critical thinking disposition.

Purpose: The purpose of this study was to examine the degree of intensive and critical care nursing competence in senior nursing students. Methods: The research method for this study comprised a descriptive survey study with a convenience sample of 113 senior nursing students from one university. The instrument entitled ICCN-CS-1, which measures intensive and critical care nursing competence, was translated by the authors following WHO guidelines for translation process. The data were collected using ICCN-CS-1. Results: The mean score of intensive and critical care nursing was above the intermediate level. The competence indices of knowledge, skill and attitude/value were also above the intermediate level, which suggests that their competence is good. For two intensive and critical care nursing domains, the nursing students' mean score of clinical competence is higher than that of professional competence. The competence of intensive and critical care is also influenced by nursing students' satisfaction in their major and clinical practice as well as their confidence in clinical practice. Conclusion: The senior nursing students' competence of intensive and critical care nursing is above the intermediate level. A consideration of the influencing factors of satisfaction of nursing major/ICU practice and confidence of ICU practice is needed in intensive and critical care nursing education.

The purpose of this study is to analyze the effects of Critical Thinking Strategy supporting argumentation activities between learners. The research question is whether the form of Critical Thinking Strategy offered to support meaningful interaction of collaborative argumentation between learners influences the knowledge acquisition, learning outcome, and student satisfaction. For this, the collaboration outcome of the group, the level of individual knowledge acquisition, the level of students satisfaction were measured as outcome of argumentation activity and their differences analyzed. This study concludes the following: A comparison of the group that was provided with Critical Thinking Strategy (test group) and the group provided with general argumentation scaffolds (compared group) showed there wasn't statistically significant differences in the quality of the learning outcome of collaboration between the groups and in students satisfaction. But there was significant difference in the degree of individual acquisition depending on the offering of scaffolding for Critical Thinking. Therefore, as premised in this study, supporting meaningful mutual interaction between learners during collaborative argumentation using Critical Thinking Strategy has a positive influence on the individual acquisition of domain knowledge. The group provided with scaffolding for Critical Thinking gained higher effect in the degree of knowledge sharing and individual acquisition of domain knowledge compared to the group provided with general argumentation scaffolding.

The differential equation, which can determine the dynamic critical loads for low parabcoic arches, is derived in this study. The dynamic critical loads of the parabolic arches subjected to a concentrated step load are nummerically analyzed for the changes of load positions. In cases of arches with different end conditions (both hinged, fixed hinged, both fixed), the effect of end conditions and that of the rises are investigated in detail. The summary of the results are the following: 1)The snapthrough does not occur when the rise of arch is very low, and the bifurcation appears clearly as the rise of arch increases. 2)The regions in which the dynamic critical loads are not defined for the both ends fixed are broader than that for the both ends hinged. 3)For all case, the load positions of minimum dynamic critical loads exsit at the near position from the end hinged. Thus, the results obtained in present study show that the magnitude of dynamic critical loads, the load positions of minimum dynamic critical loads and the regions in which the dynamic critical loads are not defined depend on end conditions of arches.
