Purpose: This study was to determine ICU nurses noncompliance of critical care nursing standards in order to provide basic data for education aimed at improvement in practice and evaluation of quality of nursing care in ICU. Methods: Data was collected from 150 nurses who work for three educational hospitals which have more than 800 beds and located in Gyeonggi province using questionnaires from September 2007 to October 2007. Results: The highest categories of noncompliance of critical care nursing standards were admission care($2.71\pm.60$) and infection control($2.31\pm.70$). The main causes of noncompliance critical care nursing standards that nurses regarded as causes were lack of attention(80.7%). ICU nurses mainly reported their noncompliance to charge nurses(89.3%) within 30minutes (84.7%). The reasons they reported were to solve problems rapidly and correctly, to reduce a harm to patients, and to prevent making noncompliance again. The reasons they didn't report were that they thought it might be not a problem and there was no change of patients conditions. Conclusion: ICU nurses noncompliance of critical care nursing standards was determined, therefore it can be used for prevention of further noncompliance.

Critical thinking ability based on a sound sense of logic is essential for analyzing a given engineering design problem and assessing it to arrive at the most plausible conclusion. Engineering design classes require students to organize their engineering design experiences through reports, and engineering design reports require detailed specifications of their tasks at each stage. Given the nature of these curriculums, design classes provide writing courses focusing on science and engineering within specialized fields, but there still lies many obstacles for communication education that embraces both general education and major subjects. This study proposes a specified step-by-step writing model for engineering design reports that encompasses critical thinking for the objective of systemizing design experiences from engineering design report writing. For the purpose of the study, the concepts and relationship between critical thinking and creative problem solving have been examined, followed by a proposal of application methods for critical thinking criteria and elements from a case example on engineering design. Furthermore, the study proposes a critical thinking-based assessment rubric for logical decision making at each stage of engineering design as well as a resulting model for engineering design report writing.

Studies are being done to replace conventional refrigerants with alternatives that have low or no ozone depletion and greenhouse warming Potentials, yet possess appropriate pro perties for a refrigeration cycle. To achieve this goal, a consistent set of thermodynamic properties of the working fluid is required. A common problem with the possible alternative refrigerants is that sufficient experimental data do not exist, thus making it difficult to develp complete equations of state that can predict properties in all regions including the vapor-liquid equilibrium. One solution is the use of the generalized equation of state correlations that can predict thermodynamic properties with a minimum number of characteristic parameters. Characteristic parameters required for the generalized equation of state are, in general, critical temperature, critical pressure, critical volume and normal boiling temperature. In this study, estimation of these characteristic parameters of refrigerants by group contribution method is developed.

Finding the critical path (or the longest path) on acyclic directed graphs, which is well-known as PERT/CPM, the ambiguity of each acr's length can be modeled as a range or an interval, in which the actual length of arc may realize. In this case, the min-max regret criterion, which is widely used in the decision making under uncertainty, can be applied to find the critical path minimizing the maximum regret in the worst case. Since the min-max regret critical path problem with the interval arc's lengths is known as NP-hard, this paper proposes a heuristic algorithm to diminish the maximum regret. Then the computational experiments shows the proposed algorithm contributes to the improvement of solution compared with the existing heuristic algorithms.

Introduction: Critical thinking involves identifying problem(s), assessing resources, and generating possible solutions and allows clinical nurses to decide which solution is the most reasonable under the given circumstances, taking into consideration the "hat ifs" and how they will affect the end result. This research was conducted to further understanding and identification of subjective factors in critical thinking in clinical nurses. Methods: The research design was a Q-Methodological Approach. Q-population was formulated from a non-structured questionnaire and interviews from 17 experienced clinical nurses. Thirty selected Q-statements were sorted by 30 experienced clinical nurses. Results: Four factors for critical thinking were identified: (1) Deductive reasoning based on causal relation, (2) Construction of an effective model based on patients' responses, (3) Formulating categories based on priorities for effective interventions, and (4) Judging validity of the situational significance on clinical performances. Conclusion: Critical thinking is an attitude and reasoning process. From this study, the frame of reference for clinical nurses in formulating critical thinking within the context of clinical settings is identified and indicates the way nurses utilize thinking skills when they care for patients and areas that need further exploration as nurses and faculty develop education systems to advance clinical performance competency.

In every sectors of industry, the Business Process Reengineering(BPR) has been applied for taking competitive advantage under rapidly changing environment. A company adopting the BPR has begun to consider the introduction of Enterprise Resource Planning ERP systems. ERP systems can integrates many core activities of business, such as manufacturing management, human resource management, financial management, supply chain management by applying the best practices to facilitate a rapid decision-making, cost reductions, and organizational control. Unfortunately, however, many tentative risk factors are existed through each phase of the introduction of ERP systems. As a result, it can bring an enormous benefits to a company or it can be a disastrous for organization. Therefore, two critical questions regarding the introduction of ERP systems should be analyzed before actual introduction has happened. They are "how can ERP systems be introduced successfully\ulcorner" and "what are the critical success factors for each phase of introduction of ERP systems\ulcorner". Through this research, We studied and analyzed the characteristics of critical success factors requiring at each phase of the introduction of ERP systems by applying the questionnaire survey method. Finally, we suggest the list of barriers and critical success factors for each phase of introduction of ERP systems.tion of ERP systems.

Purpose: The purpose of this study was to investigate the relationships among critical thinking disposition, problem solving ability, and triage competency in nurses working in Emergency Rooms (ERs). Methods: This cross-sectional study, conducted in August and September 2021, involved 118 ER nurses from three hospitals in the Gyeonggi-do metropolitan area. The data were analyzed using t-test, ANOVA, Scheffé test, Pearson correlation coefficients, and multiple linear regression analysis using SPSS for Windows version 25.0. Results: The mean score of triage competency among ER nurses was 87.63±15.65. In the regression model, age, ER experience, triage experience, critical thinking disposition, and problem solving ability predicted 52% of the triage competency. Both critical thinking disposition and problem-solving ability were noted to be significant (β=.32, p<.001; β=.36, p<.001, respectively). Conclusion: Critical thinking disposition and problem solving ability of ER nurses were identified as major factors in triage competency. To improve ER nurses' triage competency and enhance critical thinking disposition and problem solving ability, a systematic and ongoing program should be developed and implemented.

Purpose: The purpose of this study was to identify factors that affect nursing students' clinical practice ability. Methods: The data were collected from 303 nursing students who had more than 500 hours of experience in clinical practicum at 4 universities in Seoul and the metropolitan area. The instruments consisted of 27 items of critical thinking, 19 items of professionalism, 40 items of self reported leadership, 20 items of communication evaluation tool, and 61 items of nursing practice performance evaluation. Results: For the clinical practicum, most difficult for nursing students were cardiopulmonary resuscitation, fecal enema, stoma care, and blood transfusion. Clinical practice abilities were positively correlated with nursing professionalism(r=.26, p<.001), leadership (r=.16, p=.007) and critical thinking(r=.12, p=.031). Professionalism(${\beta}=.32$, p=.001) was the most significant factor influencing the clinical practice ability of nursing students. Critical thinking was the second largest factor but not significant(${\beta}=.16$, p=.058). Conclusion: The findings suggest that the nursing curriculum should include nursing knowledge and nursing skills as well as various case-based or field-based decision making training programs to cultivate professionalism, critical thinking and other abilities for clinical practice.
