This study provides a basic data necessary to design a facility of smoke management after calculating the critical velocity of the gradient scale model tunnel and reviewing its adequacy to establish an optimum disaster prevention system for a road tunnel at fire. The experiment is carried out by using Froude scaling to a scale model which is about 1/29 as big as the real tunnel, and its critical velocity calculation is calculated to the 0-2% gradient of the tunnel. The result shows that the higher the gradient is, the stronger the critical velocity, but that it doesn't affect the critical velocity so much when the gradient is less 2%. In addition, this result is studied in comparison with the results done by other researchers to review the adequacy of the critical velocity.

The purpose of this study was to develope a critical pathway for the chemotherapy of non-small cell lung cancer patients and to identify its effects after implementation. Critical pathway was developed through 5 steps including content and clinical validity tests with collaborative efforts of nurses, clinicians, and other allied healthcare professionals with the aim of improving the quality of patient care, while minimizing cost to the patients. This paper was described an evaluation of the impact of a developed critical pathway on complication rate, length of stay, costs, the interval of treatment and patient satisfaction by nonequivalent control group posttest-only non-synchronized research design.Results were compared between the two groups of patients. There were no significant differences in demographic variables and the occurrence of bone marrow suppression between experimental group and control group(t=-0.01, p=0.992). There were statistically significant decreases in the average length of stay(t=-10.45, p=0.000), in the average cost(t=-2.988, p=0.004), and in the interval of treatment(t=-6.75, p=0.000) after implementation of the critical pathway compared to control group. Also, there was a statistically significant improvement of the patient satisfaction after implementation of the critical pathway compared to control group(t=4.57, p=0.000). This paper concludes that critical pathway in chemotherapy for lung cancer, implemented in the context of an general hospital, is the useful tool to shorten the hospital stay, reduce treatment costs, and improve the quality of life in cancer patients. Further study needs to be conducted to identify other clinical outcomes including job satisfaction, collaboration among health professionals and potential for use in education. Also, it is recommended that nurses should revise continuously the developed critical pathway through clinical implementation and maintain their role of patient advocacy through monitoring pathway compliance.

Purpose: This study was carried out to describe the process and evaluation of a critical thinking class for new community health practitioners. Methods: The case study design was used to develop and evaluate a critical thinking class for 46 participants in the community health practitioners training program. The class was held two hours a week for 8 weeks. Critical thinking disposition was tested before and after the class and critical skill was graded according to the final test score. Data analysis was performed using descriptive statistics and paired t-tests using SPSS WIN 20.0. Results: Clinical critical thinking competences were identified through the literature review. The case situations with questions guiding the problem-solving process were developed and used for group discussion. Critical thinking disposition of participants was determined to have increased slightly after having taken the class. 17.4% of the participants had a competency level high enough to solve a problem and half of them stayed at the level of understanding of critical thinking. Compared with the class's satisfaction with the relevance to their jobs, the satisfaction with the learning method and instructor was high. Conclusion: The findings of this research will serve as the basis for developing critical thinking classes for community health nurses in order to improve their critical thinking competence.

In this study, the artistic background and formative nature of representative 19th century realist artists Gustave Courbet and Honoré Daumier were analyzed and applied in a fashion context. By displaying representational desires (necessary adhesions of man and society) in their work, they became characteristic matrixes of critical realism and to perceive critical realism. The purpose of the study was to apply the characteristics of critical realism to the contemporary fashion collections of Alexander McQueen. Research was conducted to analyze the characteristics that appear in the field of fashion and to review methods of expression and internal aesthetics displayed through various aspects of fashion design. Characteristics of critical realism were analyzed by researching the formativeness and periodical background of the paintings of Courbet and Daumier. Based on these characteristics, analysis was conducted to identify critical realism in the fashion collections of Alexander McQueen. Data and scope included fashion information sites, internet photo data, and video material. Critical realist characteristics were categorized into five types as follows: 'The proper borrowing of extremely realistic subjects signifies', 'satirical reconstruction and narrative composition', 'antipathetic distortions and abject representations', 'critical reproductions based on technology', and 'the maximization of ambivalent sexuality'. It was concluded that the characteristics of critical realism (recognized by the common formation of Courbet and Daumier) also appeared in Alexander McQueen's fashion collection but were inherited in a form that transcended pictorial expression due to the overall difference in use of visual arts.

Purpose : This study aimed to investigate changes in critical nursing activities from 2009 to 2020 and explore the relationship between nurse staffing and such activities in intensive care units. Methods : A total of 446,445 adult patients admitted to intensive care units in tertiary and general hospitals from 2009 to 2020 were identified using the National Health Insurance claims database. The Critical Nursing Activities Index was calculated based on the following critical nursing activities: ventilator, extracorporeal membrane oxygenation (ECMO), and continuous renal replacement therapy (CRRT). Trend analysis was performed to analyze changes in critical nursing activities over 12 years and to assess linear trends across different staffing levels. Results : The annual utilization days for ventilators, ECMO, and CRRT, as well as the Critical Nursing Activities Index significantly increased over the study period (p-for-trend<.001) in tertiary and general hospitals, except for ventilator use in general hospitals. Ventilator, ECMO, and CRRT utilization exhibited a significant upward trend with higher nurse staffing levels (Bonferroni adjusted p-for-trend<.001). The Critical Nursing Activities Index was significantly higher in hospitals with higher staffing levels compared to those with lower staffing levels (Bonferroni adjusted p <.05). Conclusion : The findings underscore the need for improved nurse staffing levels in intensive care units. Government policies should ensure that staffing levels align with critical nursing activities among critically ill patients to uphold the quality of care.
