Aim: To investigate the effect of continuing ethical education and on-site ethics-related meetings on the moral efficacy of clinical nurses and examine their perception of ethical climate in the workplace. Methods: A quantitative cross-sectional study was conducted by administering Japanese versions of the Moral Efficacy Scale (J-MES) and Hospital Ethical Climate Survey (J-HECS) to 300 nurses working at four hospitals in Japan. Respondents who underwent ethical education within the past year were considered one group, and the second group consisted of those who did not. Further, groups were formed based on the conduction of ethics-related meetings in respondents’ respective departments. The total and subscale scores of J-MES and J-HECS were calculated, and group scores were compared using the Mann-Whitney U test. Results: The 300 questionnaires that were distributed, generated 191 valid responses with a collection rate of 63%. The J-MES scores of the group that continued ethical education did not differ significantly from the group that did not receive it. Analysis of the J-HECS scores show that the group with ethical education had a significantly more positive perception of ethical climate in their workplace than the group that did not receive it (p<0.05). Moreover, the nurses who participated in on-site ethics-related meetings at their wards had higher J-MES and J-HECS scores than those who did not (p <0.05). Conclusions: Merely providing ethics education may not affect the moral efficacy of nurses. Further research is required to clarify the kind of ethics education/training needed to enhance moral efficacy. Furthermore, an environment in which ethical issues can be discussed within a department positively influences the moral efficacy of nurses. It is clear that the opportunity to simply discuss the patient positively influences the nurse"s perception.

Flow-induced acoustic resonance in a piping system containing closed tandem side branches was investigated experimentally. Velocityperturbation was induced at the mouth of a cavity by using two pumps and a block. An unusual acoustic mode change from a higher to alower mode was observed when the flow rate in the main pipe increased. This phenomenon was examined by high time-resolved particleimage velocimetry (PIV). It was found that fluid flows at different points in the cavity have some phase differences between them andthat they interact with each other. The relationship between the fluid flows was clarified and the phase difference between the acousticpressure fluctuations at different points in the cavity was obtained. Using these data, the phase delays of oscillations at different pointswere two-dimensionally mapped. This two-dimensional phase map was helpful in clarifying the feedback mechanism of self-inducedvibrations.
