Only service organizations providing service quality above customers' anticipations have survived and developed in hyper competitive environment. These organizations are more dependent on their customer-contact service employees than those providing tangible products, because of the characteristics of service, intangibility, inseparability, heterogeneity, and perishability. But few researches focused on the efficient managements or controls of service organizations in this context. Therefore, author aimed at understanding of the determinants of service organizations' control system(i.e., characteristics of service), service employees' reaction on control types(i.e., service employees' role stress), and their performance(perceived service quality by customers). First the concepts of service quality and control systems are described. Specially, author explained the differences between service quality and service satisfaction or service attitude, and the control system types and their fundamental ideologies. Second, some propositions are provided according to integrated framework developed in this paper: (1)control types according to the characteristics of service, (2)influences of control systems on employees' reactions and (3)perceives service quality by the customers, and (4)relationships between the reactions and the service quality. This paper concludes with a summary, a discussion of theoretical and managerial implications, and several suggestions for future directions.

The purpose of this study is to provide empirical and quantitative analysis on user's perceived privacy, security, and user satisfaction when providing visualization information about objects and service provider behaviors that users can not perceive in internet service process. Through previous research, we have examined the importance of privacy and security factors as a key factor to be considered for the characteristics of the Internet of things and the Internet of things. In addition, service blueprint, which is one of the service design methodologies to examine the flow of service usage in providing Internet service of things, was examined. In the flow of things internet service utilization, it is found that the things that are out of the user's cognitive area and the behavior of the service provider take up a large part. Therefore, the hypothesis that the trust of the Internet service security and the satisfaction of the user experience can be improved by providing the security visualization information about the behavior of the object and the invisible service provider in the non-contact aspect of the user and the object. In order to verify the hypothesis, we conducted experiments and questionnaires on the use of virtual objects' internet environment and conducted statistical analysis based on them. As a result, it was analyzed that visual information feedback on non - contact and invisible objects and service provider's behaviors had a positive effect on user's perceived privacy, security, and satisfaction. In addition, we conclude that it can be used as a service design evaluation tool to eliminate psychological anxiety about security and to improve satisfaction in internet service design. We hope that this research will be a great help for the research on application method of service design method in Internet environment of objects.

Naegleria fowleri, a pathogenic free-living amoeba, leads to a fatal infection known as primary amebic meningoencephalitis (PAM) in human and animals. PAM is an acute, fulminant, necrotizing, and hemorrhagic disease that leads to death in approximately seven days. In this study, we investigate the cytotoxicity of target cells and the secreted molecules of N. fowleri under the non-contact condition. The target cell (U87MG cell) treated with N. fowleri lysates showed no morphological changes and no cytotoxicity. By contrast, the U87MG cells co-cultured with N. fowleri trophozoites under the non-contact condition induced morphological changes and reduction in number. When U87MG cells were co-cultured with N. fowleri trophozoites under the non-contact condition for 30 min, 2 hr, and 4 hr, the levels of cytotoxicity of target cells were 32.3, 35.5, and 37.8%, respectively. Particularly, when the ratio of amoeba to target cells is 10 to 1, the level of cytotoxicity of target cells was 49.7% at 30 min. To show the proteins secreted from N. fowleri under the non-contact condition, we carried out 2D electrophoresis and observed 6 major proteins. Finally, these results suggest that the molecules released from N. fowleri under the non-contact condition induce the cell death and this process is an important step in pathogenesis of N. fowleri.

Railway wheels and axles belong to the most critical components in railway vehicles. The service conditions of railway vehicles became more severe in recent years due to the increase of speed. Therefore, a more precise evaluation of wheel/set life and safety has been requested. One of the major reasons of railway wheel damage is a contact zone failure by wheel/rail contact. In this paper, we conducted a rolling contact fatigue test for wheels using a specimen of wheel/rail. the behavior of hardeness and residual stress below the contact surface of the test pieces in the fatigue process were analyzed. Finally, the relation between fatigue life and contact pressure was obtained.

The purpose of this study was to investigate the effect of fairness, culture, and service points on organizational management to maximize the ability of organizational members. The subjects of the survey were selected from major hospitals, small and medium hospitals. A total of 500 questionnaires were distributed, but 404 (80.8%) were used for the final analysis. The SPSS WIN 20 program was used to analyze the collected data. The following conclusions were obtained. First, in this study, organizational fairness did not show any general difference, and fairness was obtained with relatively high scores. In terms of improving organizational culture, size of hospital there is a statistically significant difference. the larger the organization, the more the organizational culture needs to be improved. Organizational fairness were significant differences in service encounter points and size of hospital. Second, the correlation between fairness, organizational culture improvement, service contact point and management performance showed a very positive correlation. Third, fairness has no effect on business performance. However, in this study, organizational culture improvement and service contact points are statistically significant and positive (+) influence on dependent variable management performance. Therefore, in order to improve the organizational culture of the hospital, it is necessary for the CEO to the vision, core, to discuss and make a reasonable plan. In order to actively cope with rapidly changing hospital environment, it will be necessary to positively support the of new medical market and the increase of market share.

The estimation of fatigue limit for the component with complicated shape is difficult than of standard fatigue specimen, due to complex test equipment. So, we substitute maximum principle stress from FEM results for fatigue limit diagram made by standard fatigue specimen. Then we can estimate endurance safety of component with high trust. The static stress analysis, the nonlinear contact stress analysis and the model analysis for turbine blade is performed by ANSYS ver. 5.6. the comparison of maximum static stress around hole with maximum contact stress between pun and hole can make the cause of fracture for turbine blade clear. The difference of fatigue limit between fatigue test by standard specimen and in-service mechanical components is due to surface roughness and machining condition etc. In in-service mechanical components, Goodman diagram has to consider surface roughness for failure analysis. To find fracture mechanism of torison-mounted blade in nuclear plant. This study performs the static stress, the nonlinear contact stress and the modal analysis on torison-mounted blade with finite element method and makes the estimation for safety of turbine blade.
