Purpose: This study was performed to investigate the perceived relationship among professional self-concept, head nurse's leadership, and nursing clinical competency by clinical nurses. Methods: This study was a cross-sectional survey. Participants were 601 nurses working at the five general hospitals in four provincial cities, Gyeungbuk, Korea. Data were collected from July 14, 2010 to August 31 and analyzed by SPSS/PC ver 18.0 programs. Results: Professional self-concept and head nurse's leadership were slightly above the middle average, but nursing clinical competency was good. According to participants' age, marital status, job satisfaction, and length of service, there were perceptional differences in professional self-concept, head nurse's leadership, and nursing clinical competency. Nursing clinical competency could be explained by head nurse's leadership, professional self-concept, job satisfaction and length of service. Head nurse's leadership was independent variable affecting nursing clinical competency, professional self-concept was partial mediating variable, and job satisfaction and length of service were extraneous variables. Conclusion: It is concluded that head nurse's leadership is more important than professional self-concept to improve nursing clinical competency. Nursing managers should plan various strategies to improve head nurse's leadership and professional self-concept, to increase clinical nurses' job satisfaction and length of service.

The role and use of self-service technology (SST) becomes increasingly more important in the e-government service area. Users evaluate the service quality of SST in their everyday life and this evaluation works as a guideline of how SST should evolve for user satisfaction. This study classifies the types of SST according to its purpose and interface, and then investigates the causal relationship of service quality and user satisfaction. In the process, we introduced the three dimensions of service quality - usability, information, and empathy. The analysis results indicate that the three service quality dimensions have positive influence on user satisfaction. While the relationship between information and empathy is significant, that between usability and empathy is not significant. Implications and future research directions are also discussed.

Recently, various researches have been studied to support service-oriented IoT networking. This is because the IoT environment coexists with various service devices for providing the service in a certain unified area. Thus, in this network environment, an effective data delivery service is not provided in a network configuration. Also, in order to provide efficient IoT services in this network environment, new scheme is necessary to recognize services by themselves and to construct network structures for each service. In this paper, we propose a service oriented self-constructive network (SO-SCN) scheme that can construct a service-oriented network in IoT environments composed of various service devices. The proposed scheme is a method that can minimize the network overhead required for service provisioning and extend the network lifetime. Through simulation, we show that the proposed service oriented self-construction network scheme improves the performance, in terms of the number of packets generated for end-to end data transmission and the end-to-end delay.

The purposes of this study were to understand the influence of brand personality-self image congruence in quick service restaurants on customer satisfaction and to empirically analyze whether or not customers' brand identification plays a moderating role between brand personality-self image congruence and customer satisfaction. Based on a total of 478 samples obtained from empirical research from June 10 to June 16, 2010, self-administered questionnaires were completed by patrons in a metropolitan area, and data were analyzed based on frequency, exploratory factor analysis, reliability analysis, correlation analysis, and hierarchical regression analysis. Results of the study were as follows: From the factor analysis of brand personality and self-image, 5 factors, i.e. sophistication (5 items), competence (5 items), likability (5 items), trendiness (5 items), and ruggedness (5 items) were extracted. The results show that trendiness (${\beta}$=-0.151) among brand personality-self image congruence had a significant positive effect on customer satisfaction. Further, customers' brand identification (${\beta}$=0.645) had a significant positive effect on customer satisfaction. In addition, the effect of brand personality-self image congruence (only, likability ${\times}$ brand identification; ${\beta}$=0.245) in quick service restaurants on customer satisfaction was found to be partially moderated by customers' brand identification. In other words, the findings show that customers wanted to identify with a specific brand because it provides a means to continue transactions with the brand if it corresponds with their self-image or if the overall image of the brand is favorable. Limitations and future research directions are also discussed.
