The current study used the critical science paradigm to explore the kinds of oppression experienced by the families of patients in hospitals, and to suggest how the practices should be changed for problem solving. Ethnographic observations and individual interviews were peformed for data collection from the 25 family members of critically ill patients. The results revealed the powerlessness of patients' families caused by multiple oppressions. They were struggling with family-unfriendly hospital systems, negative interactions with medical staff, limited supports from health care systems, and their own resignation to fate. Strategies were discussed to facilitate changes in institutional, humane, policy, and religious/spiritual aspect. The study findings will contribute to promoting the rights of patients' families.

The paper deals with the vibration and dynamic stability of cantilevered pipes conveying fluid on elastic foundations. The relationship between the eigenvalue branches and corresponding unstable modes associated with the flutter of the pipe is thoroughly investigated. Governing equations of motion are derived from the extended Hamilton's principle, and a numerical scheme using finite element methods is applied to obtain the discretized equations. The critical flow velocity and stability maps of the pipe are obtained for various elastic foundation parameters, mass ratios of the pipe, and structural damping coefficients. Especially critical mass ratios, at which the transference of the eigenvalue branches related to flutter takes place, are precisely determined. Finally, the flutter configuration of the pipe at the critical flow velocities is drawn graphically at every twelfth period to define the order of the quasi-mode of flutter configuration.

Purpose - According to the applied studies knowledge, management implementation can improve organizational performance. The main objective of this study is to develop an understanding of critical success factors that enhance the successful implementation of knowledge management. Research design, data, and methodology - This study used Analytical Hierarchy Procedure (AHP), which is a multi-criteria decision making model that works on fuzzy logic. Using this method, researchers can find the proportion of success due to the contribution of the critical success factors (CSFs). Results - The results show that more than 70% of respondents indicate the possibility of success in knowledge management implementation. Further, the results show that top management support has the greatest relationship with the success of knowledge management implementation. This was followed by information technology, performance measurement, and culture, which had a high relation with knowledge management success. Process and activities have a moderate positive relation, while education and training has a low relation with success. Because of an inappropriate p-value, knowledge management strategies show no relation to the success of knowledge management in the Iranian health Industry. Conclusions - This study was conducted because of a critical issue in the Iranian health industry that indicated that a significant portion of the workforce would retire in 5 to 10 years. Most highly experienced and knowledge oriented employees would become eligible for retirement. Therefore, knowledge management is presented as a complete solution in the Iranian health sector.

A grid-connected inverter with critical loads should be able to supply a stable voltage to critical loads at mode change and during clearing time while detecting unintentional islanding. This study proposes a mode transfer method for a grid-connected inverter with critical loads. The proposed method, which integrates the grid-connected and islanded mode control loops into one control block, provides an autonomous and seamless mode transfer from the current control to the voltage control. Therefore, the proposed scheme can supply a stable voltage to critical loads at mode change and during clearing time. Experimental results are provided to validate the proposed method.

This study is to develop a new scoring system for rating Hazard analysis and critical control points prerequisite evaluation items for meat shops to provide a more objective and accurate evaluation of food safety compliance. The importance of each item was measured by looking at the hazard severity level and the rate of non-compliance associated with it. It was found that the new scoring system is more stringent and gives a clearer picture of compliance with the most critical safety standards, and therefore is expected to have a positive effect on the hygiene and safety of livestock products.

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.

Purpose - The purpose of this study is to contribute to the literature on casino services by investigating critical service failures using the critical incident technique (CIT) and provide effective recovery strategies that can be adopted in practice. Research design, data, and methodology - The data were collected from Asian casinos' HNI customers in China, Japan, and the Republic of Korea. This is the first study that has investigated VIP casino customers in leading Asian countries. The research used the critical incident technique (CIT) collect and a total of 227 incidents were analyzed. Results - The results show that three main categories and eleven subcategories are deduced. The first group concerns casino service system failures. The second group relates to service providers' responses to VIP customer complaints. The last group covers employees' attitudes and behavior toward customers. Conclusions - First, the most serious service problem in casinos was the service providers' attitudes rather than the service system failures. Second, Tangible recovery strategies such as "all pay" and "additional comps" were proven to enhance a casino's image and lower customers' intentions to switch. Customers, however, preferred intangible recovery strategies such as considerate responses, reliable problem management, sincere apologies, and accurate explanations.

This study examined the Family and Consumer Sciences (FCS) National Standards with some examples at the state level, analyzed the previous studies relevant to curriculum implementation in the USA, and explored critical success factors in moving toward the new perspective curriculum in exemplary states. The process, in which the FCS discipline struggled to clarify the identity and image as well as to find the mission and vision, produced the FCS National Standards in 1998 and 2008 in the USA. The FCS National Standards were established to fulfill the mission of the FCS based on a critical science perspective. The previous research on a state level implementation indicated that the majority of FCS state administrators agreed that the National Standards positively influenced curriculum development. The critical success factors in integrating National Standards into local programs included the dissemination of thephilosophical works of Marjorie Brown, the foundation of the FCS curriculum with a critical science perspective, the establishment of National Standards corresponding to the philosophical works and a critical science perspective, the openness of state FCS administrators to educational reform, the construction of an infrastructure to support reform, and the commitment by university professors to develop a teacher training program. The critical success factors identified can be employed as an informative guide for the future development and implementation of the Family and Consumer Sciences curriculum in Korea.

This study developed an integrative curriculum design plan for Home Economics through a deliberation method. This study established a research framework to integrate the deliberation models of Schwab, Walker, and Reid that inherited the intellectual tradition of curriculum deliberation along with the practical reasoning process of Brown and Paolucci from a critical science perspective. The practical research problem was formulated as "What should be done to develop a Home Economics integrative curriculum?" To address this practical research problem, deliberation with deliberators of each small, medium, and large groups was processed for the development of integrative curriculum design plans. An initial proposal was developed from small group deliberation processes. An initial proposal was examined and an alternative plan was developed from medium group deliberation processes. An alternative plan and its consequence were re-examined from large group deliberation processes. The authors finalized a proposal organized on four valued ends of self-formation, intersubjectivity, social action, and life skills. A practical problem focused integrative curriculum was developed and proposed to pursue the four valued ends. The suggested final practical problem focused curriculum demonstrates the power of Home Economics to contribute to the advancement of individuals, families, and society as well as the practical empowerment of students.
