Background: The objective of this study was to evaluate the efficiency of an emergency ambulance system and to investigate socio-economic and clinical characteristics associated with emergency ambulance service. Methods: Based on 2011 Korea health panel, unmet need and inappropriate use of emergency ambulance service were measured by Gibson in 1977. Furthermore, the factors associated with unmet need and inappropriate use of emergency ambulance service were identified by Fisher's exact tests and multiple logistic regression models. Results: Unmet need, defined as the proportion of emergency patients who clinically need ambulance transportation but do not receive it, was found to be 59.8%. Inappropriate use, defined as the proportion of emergency patient receiving ambulance care who did not clinically need it, was found to be 37.2%. There were statistically significant differences between appropriate and inappropriate groups in overall variables of socio-economic and clinical characteristics. Specifically, gender, age, relationship to household, and reasons of visiting emergency department (accident/disease) were statistically significant factors associated with appropriate use of emergency ambulance service. Conclusion: Unmet ambulance need is a useful measure for patients needs assessment, and inappropriate ambulance use is a valid criteria in judging the efficiency of emergency ambulance system. To improve and understand emergency ambulance system, unmet need and inappropriate use of emergency ambulance service should be more concerned.

Smartphone services seem to be appealing to people worldwide and show rapid growth in mobile service market. Based on the theoretical framework like attachment theory and self-congruity theory, we developed the research model and proposed six hypotheses. An analysis of 113 smartphone service users found that continued use intention in smartphone services is affected by uses' attachment to the service. We also found that the attachment is significantly increased by self-congruity, customization, and perceived usefulness. Our aim was to gain insight into ways of creating an environment that facilitating continued use intention of smartphone services. This study has important implications for academic researchers and practitioners who seek to understand why smartphone service users continuously use their smart phone services. Other practical implications of these findings and future research implications are also discussed.

This research attempts to identify N-screen users' motivational and dissatisfying factors in relation to their willingness for continued future use of the service. An on-line survey was conducted (N=558) to reveal five major factors for N-screen use: Medium usability (interface usability and daily usefulness), Socialness (potential for social use with family and friends), Mobility (use without restraints of time and space), Contents (diversity of contents catalogue and related information search), and Habitual use. With exception of Contents factor, four of those factors were proven to be meaningful predictors of the users' willingness for continued future use of N-screen service. Meanwhile, two factors were extracted as the major source for N-screen users' dissatisfaction: Customer service (dissatisfaction associated with the service itself) and Contents (dissatisfaction relating to contents use). The effect of those two dissatisfaction factors was examined. The results show that Contents dissatisfaction, in comparison with Customer service dissatisfaction, was a more powerful predictor for discontinuing of N-screen service use.
