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.

As ten years have passed since national parks were adjusted and released inceptively, it is the time for evaluating the effectiveness of the national park policy and improving it on the basis of the evaluation result. In this study, the method of appraising the environmental and socio-economical ripple effect on the implementation of national park regulation were provided, based on the institutional consideration, the environment analysis, the survey of residents consciousness, the statistical analysis and so on. It is applied to target sites where were released from national parks, and the policy direction was suggested for sustainable use and management of national parks. National parks, that exhibit various characteristics depending on geographical and local conditions, were categorized through the statistical approach. Released sites from Seoraksan National park, where was categorized as the core national park for sustainable use and management, were evaluated environmentally based on the time-series analysis of environmental thematic maps and socio-economically based on the survey on residents perceptions. As a result of this study, the environmental effect of released sites has been declined or threatened, and the residents' economic, social and living condition in these areas are still not improved(p<0.05) since the adjustment of national parks. Based on the policy approach reflecting regional characteristics, natural resources are kept and enhanced for the sustainable use and management of national parks. And a consensus on the national park policy of national park should be developed between local residents and voluntary participation and public awareness should be attracted from them, based on the construction and the supplement of the infrastructure.

Nowadays, countries all over the world are deeply concerned about pollution in the global environment, so they are seeking various ways to adequately disposal of waste. Still, the environmental situation seems to be getting worse and worse. It is evident that such wastes and pollution have been endangering human life nestled in this globe up to the end of the 20th century. We should not, however, tolerate such human misconduct and mal-management of resources any more in the new millenium. For realizing a society that is sustainable for generations to come, it is important to establish a social system for minimizing wastes, promote re-use and recycling, and develop technology for improving recycling efficiencies, including product designs that facil-itate re-use and recycling and innovative technologies for processing wastes. In this paper, reviewing the current status of Korean waste problems, the governmental policy and specific approach for the establishment for recycling society is considered.

Intermediaries are presenting not only transactional information that orchestrates electronic transaction, but also market related information and knowledge useful for sellers' understanding of the market status. However, we do not have strong evidence that the market related information and knowledge is properly utilized by sellers and that it has an actual influence on sellers' performance. According to the research result, absorptive capacity and the pattern of information system utilization is statistically significant to sellers' performance mediated by operational efficiency and market knowledge creation. Especially, explorative utilization of information system and realized absorptive capacity has a stronger influence on sellers' performance mediated by market knowledge creation. With this research result, this study maintains that sellers are required to absorb and utilize market related information and knowledge more actively through explorative utilization of information system to achieve better performance in the e-marketplace. On the other hand, intermediaries are recommended to provide abundant and valuable market related information and knowledge for the sellers to build up better e-marketplaces.

We estimated the price range of electricity transactions under the prosumer system, considering the spread of renewable energy and the prospect of introducing a surplus power trading system between power consumers in Korea. The range (min/max) of power transaction prices was estimated by prosumers and consumers who could purchase electricity from utilities if needed. It is assumed that utilities purchased electricity from prosumers and consumers under a Time-of-Use (TOU) rate, trading at a monthly price. The range of available transaction prices according to the amount of power purchased from utilities and the amount of transaction power was also estimated. The price range that can be traded is expected to vary depending on variables such as the TOU rate, purchased and surplus power, levelized cost of electricity, etc.
