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.

정보기술의 활용이 마케팅 전략의 중요한 부분으로 부각되는 시장 환경에서 본 논문에서는 패스트푸드 레스토랑에서 주문시 Self Service Technology(SST)를 사용 할 때 기술준비도와 소비자 준비도에 따른 사용동기, 태도, 사용의도의 차이를 검증하고자 하였다. Parasuraman이 TRI를 개발한 이후 SST와 TRI를 접목한 연구가 이루어져 왔지만 여전히 부족한 실정이다. 소비자 준비도 역시 SST사용에 대한 소비자의 동기와 태도 및 의도와 직접적인 영향을 미칠 수 있지만 이에 대한 연구는 이루어지지 않았다. 이에 본 연구에서는 패스트푸드 레스토랑에서 터치스크린 SST를 도입함에 있어 소비자의 기술준비도와 소비자 준비도가 Dabholkar & Bagozzi(1994)가 제안한 SST 핵심태도모델에 미치는 영향을 고찰하였다. 이때 모든 소비자와 상황적 요인에 따른 차이를 파악하고자 자아의식, 상호작용욕구, 기술에 대한 두려움 등의 소비자특성과 지각된 대기시간, 지각된 과밀 등의 상황적 요인에 따른 조절 효과를 검증하였다. AMOS 18.0프로그램을 사용하여 구조방정식 모델로 분석하였고 연구 결과 기술준비도 중 낙관성은 사용용이성과 재미 동기에 유의한 영향을 미치는 것으로 나타났다. 혁신성은 사용용이성과 성과에 유의한 영향을 미치는 것으로 나타났다. 역할의 명확성, 능력 및 자아 효능감으로 구성된 소비자준비도는 사용용이성, 성과와 재미 등 모든 SST사용동기 요소에 기술준비도보다 강하고 유의한 영향을 미치는 것으로 나타났다. 마지막으로 SST 핵심태도모델 내의 SST 사용 동기, 사용 태도 및 사용의도 간의 관계에서 소비자 특성과 상황적 요인의 조절효과를 검증한 결과 지각된 과밀을 제외한 모든 변수들이 조절효과를 지니는 것으로 나타났다. 이러한 연구 결과를 바탕으로 터치스크린 SST를 도입하려는 기업에 실무적 제언을 하였다.

Design/methodology/approach This study was designed to investigate the structural relationship between perceived value, perceived risk, network effect, usefulness, trust, and intention to use. Empirical analysis was done using SPSS 21.0 and AMOS 21.0 Findings Based on the results of this study, the following conclusions can be drawn. First, it was concluded that the higher the economic value of the accommodation sharing service is, the more useful and reliable the service is. Second, the higher the experiential value of the accommodation sharing service is, the higher the usefulness and reliability of the service are. Third, it was concluded that the higher the value of the mutual benefit of the accommodation sharing service is, the higher the trust level of the service is, but not the usefulness of the service. Fourth, it was concluded that the higher the perceived risk of accommodation sharing service is, the lower the service trust level is, but the service usability is not affected. Fifth, it was concluded that the larger the network effect of the accommodation sharing service is, the more useful the service is, but it does not affect the reliability of the service. Sixth, it was concluded that the higher the overall reliability of the accommodation sharing service is, the higher the usefulness of the service is. Seventh, it was concluded that the higher the overall usefulness and reliability of the accommodation sharing service are, the higher the intention to use the sharing service is. Finally, in order to test the effect of the experience on the use of trust and usefulness of the accommodation sharing service, multiple group analysis was conducted to examine the relationship between trust and usefulness, It is shown that there is a moderating effect in the path.
