Objectives : The purpose of this study was to identify the relationship between decision-making types, public entrepreneurship, and performance management of local public hospital directors. Methods : A questionnaire survey was carried out to assess the dependent variables of directors' decision-making types and public entrepreneurship. The analysis of management performance was carried out through a comparison between 2016 results of, data of variation rate on medical revenue and change rate on medical profit and results in 2015. Results : Results indicated that local public hospital directors who used rational decision-making showed better performance management. The analysis showed that enterprise had a greater positive effect (+) on variation rate of medical revenue than that of innovation. However, innovation had a higher positive effect (+) on change rate of medical profit than that of enterprise. These results suggest that innovation and enterprise have a major influence on performance management. Conclusions : The survey used for this study suggests that an education and training program is needed to improve public hospital directors' ability for rational decision-making, public entrepreneurship and performance management. Additionally, the policy change guaranteeing autonomy within the proper range is demanded that Local Public Hospital Director having spirit of innovation and enterprise achieves peak capacity and have responsibility for management.

This study was intended to analyze the average abatement cost (AAC) of forest carbon offset projects to suggest a basic credit price for government purchase of forest carbon credits. For this purpose, an a/reforestation project and a forest management project were designed with 30 years of project period. It is assumed to plant pine trees (Pinus densiflora) for the a/reforestation project, while it is assumed to replace rigida pine trees(Pinus rigida) with oak trees (Quercus acutissima) for the forest management project. For each project, the forest carbon stock was calculated and the revenue and the cost were analyzed with standardized management activities. Korea Forest Service has supported private forest owners the cost of management activities and the consulting fee for designing carbon offset project. Therefore, the AAC were analyzed for two cases : the one with subsidy for consulting fee (case 1) and the other with subsidy for both consulting fee and management costs (case 2). In addition, the sensitiveness of AAC was analyzed according to the 4 credit prices : ￦5,000, ￦10,000, ￦15,000 and ￦20,000. The result showed that the AAC analyzed for the case 1 was so high that net revenue would not be expected from all project types with any credit price. However the AAC analyzed for the case 2 was relatively lower than the AAC of case 1. Net revenue was expected from a/reforestation project with credit price over ￦10,000, while from forest management project with credit price over ￦15,000. Based on the AAC analyzed in this study, ￦15,000 was suggested as the basic price for government purchase of forest carbon credit.

This paper analyzed what kind of institutional scheme for domestic policy instruments to reduce GHG emissions are desirable for Korea in complying with the international efforts to mitigate climate change, by focusing on independent abatement(equivalent to the imposition of carbon tax) and domestic emission trading. It also examined the economic and environmental implications of recycling the government revenue created from implementation of those policies. By utilizing a dynamic CGE model, this study shows that the economic cost under independent abatement is projected to be higher than that under emission trading. It is because under independent abatement scheme each emitter in economy must meet its emission target regardless of the abatement cost. On the other hand, emission trading allows emitters to reduce the marginal cost of abatement through trading of emission permits. In designing future domestic policies and measure to address the climate change problem in Korea, therefore, this study proposes the introduction of domestic emission trading scheme as the main domestic policy instrument for GHG emission abatement. In terms of double dividend, in addition, this study shows that both independent abatement and emission trading schemes under various assumption on the revenue recycling may not generate the double dividend in Korea.

This study was designed to find out the factors which influence on the financial performance of the hospital. Out of 32 provincial hospitals which were established by the government, 10 hospitals were selected as sample hospitals. Ten hospitals were divided into two groups(5 hospitals each), one of which was profit-making and the other loss-making. The criteria in selecting profit or loss-making hospitals was net profit to total revenue. The major finding of the study was as follows; 1. Whether or not a hospital had specialized in certain departments was proved to be the major factor influencing on the financial performance. Three out of five profit-making hospitals could harvest following results by operating specific departments. (1) Man powers needed for the operation of specific departments were 14.6 persons per 100 bed, which was only 1/7 of the general hospital. (2) The number of doctors has not increased in proportion to the increase of the number of beds. (3) Ratio of total revenue to MD.'s payroll expenses of the profit-making hospitals was 75.0% higher than the loss-making hospitals. (4) The average length of stay of specific department was very long(388.1 days). However, the specific departments were found to have contributed much to the financial performance because the occupancy rate of such departments was very high(94.5%). 2. The headcount per 100 bed of the profit-making hospitals was 23.9 persons(24.0%) less than the loss-making hospitals and the ratio of payroll expenses to total revenue 15.1% less. 3. Averagel revenue per specialist of the profit-making hospitals was 100 million(25.1%) more than loss-making hospitals and the ratio of total revenue to MD's payroll expenses of profit-making hospital was 75.0% higher. 4. Profit-making hospitals have introduced new systems or renovation in 36 fields, such as incentive payment system, utilization of contracted man powers, change of the payroll structure of the nurses, specialization in certain departments, etc; however, loss-making hospitals introduced only 25 new systems or renovations. These kind of renovation could not be achieved without the cooperation of the labor union and the strong will of the top management. Therefore, it could be said that the labor union of the profit-making hospitals seems to have been very cooperative compared with that of loss-making hospitals.

Purpose - Recently, the importance of rapid change in business models is more and more increasing as the change of information technology environment. Therefore, a variety of business models have emerged. On the other hand, there is no company that can generate revenue. Many enterprises are still maintained while they are changing only their appearance of the business model. Business model is important in e-commerce. However, a lot of researches are targeted only in Web sites. Thus, e-commerce companies do not have the infrastructure for measuring and business models. The purpose of paper is to evaluate factors which are related with the structuring of the e-commerce success. And it proposed a financial items and non-financial items. From the perspectives of administrators and managers, the paper researches the possibility for E-Commerce Evaluation Model as a valuable criteria in measuring business model. Research design, data and methodology - The methods are taken by the classification for the type of business-to-business transactions, transactions subject, and the degree of integration and innovation capabilities. Financial and Non-financial value is used to build E-Commerce Evaluation Model. Evaluation items in Administration's perspective are composed with enhance the effectiveness of the mission, improving efficiency of the administration, and control of costs. Evaluation items in the customer's perspective were measured by customer participation and cooperation with customer Satisfaction. In the case of researching the information system's perspective, three criteria are used such as adequacy of the development process, improvement of the quality of service, and maintenance of standardized information technology. In researching for the ICT competence's perspective, evaluation items were composed of enhanced user capabilities, utilizing new technologies, and empowerment of information workers. Results - In this paper, E-Commerce Evaluation Model with financial and non-financial perspectives shows the possibility to be criteria in the case of measuring business model. Moreover, it gives the positive expectation to be successful criteria. But the research may have ambiguity in its essential concept because it cannot avoid the limitation in selecting evaluation tools from merely the model. It is impossible to exclude the possibility in omitting specific properties which may take place in actual case study. Therefore, In hereafter research, it is necessary to include actual case study research in selecting evaluation tools in order to improve the limit point. Actual measurement items which are derived from actual case study should be subdivided, and it would be more effective to complete the research. Conclusions - In rapid change in business models, there are various kinds of business models. But it is general situation that companies which adopted business models have not brought in revenue. For this reason, E-Commerce Evaluation Model is needed as an important factor for the structuring of the e-commerce success. Although it has the limitation in selecting evaluation tools from model, E-Commerce Evaluation Model proposes the implication for measuring business models as a valuable criteria.

본 연구에서는 수질배출부과금제도의 부과체계를 분석하고 개선 방안을 연구하였다. 수질배출부과금제도는 환경오염 원인자에게 처리비용을 부담시켜 환경자원을 효율적으로 사용하도록 하는 경제적 유인 목적을 가지고 있으나 현행 수질배출부과금제도는 행정 규제적 성격이 강하다. 즉, 배출허용기준을 설정하여 이를 위반한 배출업소에 대하여 사업장 규모, 지역, 위반 횟수, 오염물질별 초과율을 고려한 누증적 부과계수를 적용하여 실제 환경오염 비용을 훨씬 초과하는 형벌적 성격의 부과금을 부과하고 있다. 그러나 과도한 부과금 부과로 배출부과금 징수율은 환경관련 부과금 중 가장 낮은 수준이다. 따라서 본 연구에서는 규제적 성격의 부과체계를 개편하여 경제적 유인제도로 수질배출부과금제도를 개편하는 부과체계 개편안을 연구하였으며 이에 따른 부과액 및 징수액 변화 효과를 추정하였다. 추정 결과를 보면 현행 부과금 부과액은 오염물질 처리단가의 약 4배 이상을 부과하고 있어 환경자원의 비효율적 배분을 초래하고 있음을 보여준다. 아울러 과도한 부과금 부과체계를 개선하는 경우에는 징수율도 제고되어 수질배출부과금제도의 기능을 회복할 수 있음을 보여준다.
