  • The main object of this experiment is to estimate the hydrodynamic forces acting on a submerged streamlined body placed in a one-end-opened cylindrical tube moving with certain translational velocity. The best experimental design for this object is mimicking real situation, however sizes of model body and cylinder tube are just the same as those of real, for avoiding scale effects, mimicking real situation is not realizable. Hence, in this experiment, target body and cylindrical tube were designed to be towed with varying body position relative to cylindrical tube. For measuring hydrodynamic forces and flow velocity in the cylindrical tube, six one-component load cells and several one-hole Pitot tubes were used. Several conditions were checked with various end-plates those had different opening areas. Experiment results show that forces and flow velocity had different tendency with those expected, and the presence of a end-plate slows down the flow velocity in the cylindrical tube and affects pressure field in the tube to push the model submerged body forward of the tube. This tendency grows with decreasing opened area.

  • Examples and experiences of risk management on radiation under prolonged exposure situation are shown. The accident of the Fukushima dai-ichi nuclear power plant after the great east Japan earthquake (11 March, 2011) elevates background level of environmental radiation around the east Japan. For example, ambient dose equivalent rate around Tohkatsu area next to Tokyo located about 200 km-south from the plant, is about 0.1-0.6 micro-Sv $h^{-1}$ mainly due to $^{134}Cs$ and $^{137}Cs$ falling on the ground soil. This level is about double or up to ten times higher than the genuine natural level around the area. International Commission on Radiological Protection (ICRP) recommends how to face the existing exposure situation; that is the prolonged exposure situation. Referring to ICRP's reports and/or related international/domestic documents, we have been discussing and acting to gain public's safety and relief, who have a possibility to be exposed to prolonged lower-dose radiation. Here, we introduce our several experiences on risk management, especially focusing on risk communication, radiation education to public, and stakeholder involvements into making decision in local governments on radiation protection, relating to the accident.

  • It is important to predict the hydrodynamic maneuvering derivatives, which consist of the forces and moment acting on a hull during a maneuvering motion, when estimating the maneuverability of a ship. The estimation of the maneuverability of a ship with a change in the stern hull form is often performed at the initial design stage. In this situation, a method that can reflect the change in the hull form is necessary in the prediction of the maneuverability of the ship. In particular, the linear hydrodynamics maneuvering derivatives affect the yaw checking motion as the key factors. In the present study, static drift calculations were performed using Computational Fluid Dynamics (CFD) based on Reynolds Average Navier-Stokes (RANS) for a 40-segment hull. A prediction method for the linear hydrodynamic maneuvering derivatives was proposed using the slender body theory from the distribution of the lateral force acting on each segment of the hull. Moreover, the results of a comparison study to the model experiment for KVLCC1 performed by KRISO are presented in order to verify the accuracy of the static drift calculation. Finally, the linear hydrodynamic maneuvering derivatives obtained from both the model test and calculation are compared and presented to verity the usefulness of the method proposed in this study.

  • Purpose: The purpose of this study was to provide basic data to improve coping abilities of elementary school students in emergency situations. Method: The data were collected from 1633 3-6th grade elementary school students using a self-report questionnaire. Results: 1) The mean score for the coping ability of the students was low at .38(${\pm}.36$). 2) The mean scores for the 8 categories were, [Care for common symptoms], .54(${\pm}.48$), [Call for help & check], .47(${\pm}.43$), [Care for injury by heat cold & foreign body], .39(${\pm}.45$), [Care for tissue damage], .36(${\pm}.44$), [Offering help], .36(${\pm}.42$), [Rescue & escape], .31(${\pm}.51$), [Evacuation], .28(${\pm}.49$), and [Appropriate response for the situation], .27(${\pm}.43$). The mean scores for 2 areas were, 'Acting tips', .35(${\pm}.36$) and 'First aid', .42(${\pm}.40$). There were significant differences in coping ability according to students' gender (t=4.964, p<.001), and family type (t=-2.484, p=.013). 4) Among the categories, there were significant correlations between all 8 categories and significant correlation between 'Acting tips' and 'First aid' (r=.808, p<.001), 'Acting tips' and 'Coping ability' (r=.956, p<.001), and 'First aid' and 'Coping ability' (r=.946, p<.001). Conclusion: The findings indicate a need for programs to improve the coping ability of elementary school students in emergency situations.

  • Recently emotional labor is an essential situation for hospital employees in relation to surface and deep acting as the core of emotional labor strategies. This study empirically examines the relation between hospital employees' emotional intelligence and emotional labor strategies in the context of emotional labor. For empirical experiments, we conducted a questionnaire survey targeting hospital employees, and we employed the method of Partial Least Squares (PLS) for data analysis. Major findings are as follows. Hospital employees' emotional intelligence including self emotion appraisal, others' emotion appraisal, regulation of emotion, and use of emotion, have a significantly positive effect on hospital employees' deep acting. And hospital employees' deep acting has a significantly positive effect on hospital employees' organizational attachment, knowledge sharing intentions, and innovative activities.

  • The purpose of this study was to realize and apply Taekwondo's technology and the fact that actors on stage and screen have much in common. In the meantime, there have been many prior studies on the development of the theoretical field. However, there is a slight lack of practical development and development plans, and it is time to improve. This seems to be a lack of practical experience leading to the creation of physical images. In that sense, I think that it should be supported by the complement of concrete and detailed research that seeks to make changes in open technology significantly. Considering this situation, it is necessary to further develop the practical field in parallel with the theoretical field. Therefore, I suggested the principle of physical behavior through Taekwondo technology and the development of acting skill. The performance training using these taekwondo techniques is meaningful research.

  • This study concerns the role of costume in Shakespeare\`s history plays from the viewpoint of the role theory. The term “role” has been used to represent the behavior expected of the occupant of a given position or status. A specific role can not be successfully performed without the aid of the costumes. Costumes are adopted in relation with a specific role. The term ‘role’ had been borrowed from the drama. The similarity between the role on the stage and the role of the social man had been recognized. The similarity between the role on the stage and the role of the social man had been recognized. The typical examples in which the costume help to make access to a specific role and can be effectively exploited for the performance of the role are manifested in the history plays of Shakespeare. Thus, our goal in this study is to analyze the role of costume which appears in Shakespeare\`s history plays from the viewpoint of the role theory. The role of social status and position reflects sex, age, occupation, class, economic position of the characters. In his works, the crown and the mace represented not only the throne but also a previllege and supreme position. The situation role of costume could be widely used for visualizing the psychological situation and external environments of the characters on the stage. The disguise role hided one\`s status, thereby makes possible acting other\`s position. The costume also could symbolize the social status, position, rank, occupation, and the situation, and functioned as a media fo delivering messages to others. The costume performed the role of the physical and psychic protection, and provided its wearer with consolation and peaceful mind. The costume reflected the custom of a society through its wearing configuration. The costume (or a uniform) adopted by a group notified the characteristics and the expectation of action of the group to others. The results obtained from this study can provide useful cues for understanding the role action in the social structure. This kind of understanding reveals the costume phenomena in real life, allows one to perform roles properly and efficiently, and opens our insight on the overall aspects of the costume culture.

  • Purpose: We explored emergency nurses' experiences of coping with moral distress. Methods: A qualitative research design was used. We conducted in-depth interviews with 11 nurses working at a regional emergency medical center in South Korea. Data were analyzed using conventional content analysis. Results: The main theme of nurses' coping with moral distress was "a passive emotion-based response." We also extracted three categories of coping strategies: "uncritical adaptation to anguished situation," "self-justification for not acting," and "flight from ethical decision making." Conclusion: Nurses coped with moral distress in a passive and emotional way, possibly because of perceived incompetence and compliance to an organizational hierarchy. The findings imply that effective approaches to addressing moral distress in emergency nurses are needed at the individual and organizational levels.
