Purpose: The purpose of this study was to investigate the experience of nursing students who volunteered as dementia partners for elderly persons with dementia. Methods: This qualitative study utilized focus group interviews to investigate the experiences of 20 nursing students who performed dementia partner activities for more than one year. Data were analysed using an inductive content analysis approach based on Elo & Kyngäs. Results: The analysis yielded the following four major themes: "becoming a dementia expert," "becoming an evangelist for prevention of dementia," "overcoming prejudices against aged with dementia," and "acquiring motivation and skills of geriatric nursing" That means the experience as a dementia partner serves as an opportunity to broaden human understanding and shows its potential as a means to complement the effectiveness of practical nursing education. Conclusion: Dementia partner experiences have changed the perception, attitude and behavior of nursing students about the aged with dementia, so there is a need to extend this kind of experience to other students in nursing. Moreover, educational policy support should be continuously provided for this purpose.

Since large-scale commercial wind turbine generator systems such as MW-class wind turbines are becoming widely operated, the vibration and distortion of the blade are becoming larger and larger. Therefore the soft structure design instead of the solid-design is one of the important concepts to reduce the structural load and the cost of the wind turbine rotors. The objectives of the study are development of the fluid-structure coupled analysis code and evaluation of soft rotor-blade design to reduce the unsteady structural blade load. In this paper, fluid-structure coupled analysis for the HAWT rotor blade is performed by free wake panel method coupled with hinge-spring blade model for the flapwise blade motion. In the model, the continuous deflection of the rotor blade is represented by flapping angle of the hinge with one degree of freedom. The calculation results are evaluated by comparison with the database of the NREL unsteady aerodynamic experiment. In the analysis the unsteady flapwise moments in yawed inflow conditions are compared for the blades with different flapwise eigen frequencies.

The purpose of this study was to analyze the formative beauty of metro sexual expressed on the 21C men's fashion. in 21C, metro sexual is being accepted as an object to lead the world consumption culture, and it is said to be most appropriate to the definition as a model that can determine the most modern men. Moreover, with well being life style, it shows characteristic that expresses chic sense through fashion. The results of the study were as below. 1. In recent men's wear, sensory feminine that looks young and trendy is being presented through clothes, rather than the image of men who are strong. Therefore, by wearing splendid flower print, bold color and gorgeous accessories, men send off their attractions. 2. The recent body king syndrome gave new aesthetic value on men's body. Therefore, men's body is becoming cultural icon of metro sexual as another face that shows social status and cultural taste. 3. The men's image of metro sexual that is felt from softer skin and hair than women, and well-built body is appealing more through body conscious look. Here, men's body silhouette is being sublimated aesthetically through design with various materials such as see-through and leather etc., and this is body conscious image that can be seen only in metro sexual. Like this, metro sexual fashion sense was expressed by feminine softness sometimes, and beautiful body silhouette sometimes by expressing one's sexiness enough, being away' from conceptual masculine. Therefore, the appearance of metro sexual can be understood that men's body exposure is becoming a social virtue that expresses beauty.

Recently, the range of using Internet in business is expanding rapidly. And through Internet, companies are strengthening both their internal efficiency and their external competitive advantage in the market. In recent years, building and managing companies' web sites are becoming unavoidable tasks in business. Such a trend is becoming more imperative in business over the world. There is a great deal of research in progress to study the cases of companies with increasing performance from the use of their Internet web sites. But it is considered that there has not been enough of study in the area of levels of Internet application in business especially in strategic areas and application levels among countries. This research is in the same line of the research that was carried out on such topics in 1999. study in 1999 showed that there are significant differences in the usage levels of Internet in business between countries with long history of using Internet and those who are not. The 1999 study also suggested the model on development stages of Internet usage in business. This study is the continuation of the 1999 research and used two years of data to compare and analyze the trend of the Internet development stages in leading corporations in Korea, U.S.A., and Japan. This study found that there have been significant developments in the ability to use Internet in business in three countries. The differences in Internet usage level in each stage among different countries are compared and analyzed in this study.

Recently, global warming and environmental pollution are becoming more important, and fuel economy is becoming important. Each automobile company is actively developing various new technologies to increase fuel efficiency. CVVD(Continuously Variable Valve Duration) system means a device that continuously changes the rotational speed of the camshaft to change the valve duration according to the state of the engine. In this paper, VVT(Variable Valve Timing) and CVVD were applied to a single-cylinder diesel engine, and the characteristics of intake and exhaust flow rate and in-cylinder pressure characteristics were analyzed by numerical analysis. In order to analyze the effect of CVVD on the actual engine operation, the study was performed by setting the valve control and injection pressure as variables in two sections of the engine operating region. As a result, In the case of applying CVVD, the positive overlap with the exhaust valve is maintained, thus it is possible to secure the flow smoothness of air and increase the volumetric efficiency by improving the flow rate. The section 2 condition showed the highest peak pressure, but the pressure rise rate was similar to that of the VVT 20 and CVCD 20 conditions up to 40 bar due to the occurrence of ignition delay.
