현재 시행 중인 부하관리 프로그램들은 거의 대부분 간접부하관리 방식에 의존하고 있으며, 이러한 간접부하관리 프로그램들은 요금혜택에 기반을 두고 있다. 직접부하관리가 우리나라에 도입된 것은 2001년 5월이며, 이러한 직접부하관리 프로그램은 간접부하관리 프로그램에 비하여 다음과 같은 다양한 장점을 가지고 있다. 1) 부하관리 자원의 이용 가능성(availability)이 간접부하관리에 비하여 상대적으로 높다는 것과, 2) 기존의 간접부하관리 프로그램에서의 성과계량, 즉, 부하관리 실시에 따른 피크 수요감소량을 명확하게 알 수 있으므로 전력회사가 장단기 수급계획을 수립하는데 보다 확실하게 이를 고려할 수 있다는 것과, 3) 부하차단의 주체가 전력회사가 되므로 간접부하관리 방식이 안고 있는 수용가 부하차단의 불확실성이 낮아지며, 4) 궁극적으로 비용효과가 간접부하관리보다 큰 유용한 자원이다. 본 논문에서는 이러한 직접부하제어자원의 개요와 전력시장 참여 현황 및 해외사례를 소개하고자 한다.

We develop a business model for facade cleaning service robot system that provides service by meeting the market needs and environments. The size of the facade cleaning market is growing rapidly in recent years due to the increasing importance of indoor space and the modern trend of building construction methods. Also, maintenance of exterior appearance of buildings has become an important factor in residential and commercial facilities. Though demand for facade cleaning services is rising, the current facade cleaning services are performed dangerously in a human labor-dependent way. It is desirable that the existing human resource service should be replaced with robot-based services. In addition, quantitative analysis of rental pricing model was conducted to propose effective launch of products to the market. The robot system is economically attractive from the consumer's point of view. When the actual facade cleaning robot service is released, it is expected that verification of the business models and more accurate analysis with specific figures can be performed.

The domestic ESCO project was introduced in 1992 as one of the energy efficiency improvement programs. In recent energy market, the changes in the market conditions such as smart grid, renewable energy, and the importance of demand response became important issues. As the diversified business models are required, examples of overseas exercises are examined. Business areas in Europe or the US where the ESCO industry has been active include measures to improve the efficiency of energy facilities in all areas, ranging from energy supply facilities and energy services to end users. This type of ESCO overseas business model can be classified into various types such as project execution method, supplier demand management, financing method, climate change and emission rights, new and renewable energy, and other criteria. In this study, we propose to adopt IEC (Integrated Energy Contracting) contract method in domestic ESCO market for additional business models. Current convention of listing the specific individual business types being allowed by regulation turned out to be obstacles to the revitalization of the related market. In order to achieve the goal of energy conservation, it is recommended, instead, to revise the current funding guidelines to be a negative system.

For analyzing resources demand appropriately, corresponding demand data is essential. But it is hard to get the suitable data of each resource demand, because every resources has various type as refined and many kind of alloyed. That reason makes many analyses to employ the data of refined metals as the representative quantity. But those refined metals are factors for producing final goods so those in domestic market are not always meant for producing domestic end goods. Thus in this paper, the domestic demands of refined copper, lead and zinc are analyzed empirically with 'intensity of use' and foreign countries' income variable applied model for recovering the data availability.

The market-based fisheries resources management system was reviewed and the improvement scheme was studied for seeking the sustainability of marine ecosystems and their fisheries resources. A demand-side policy is currently emerging to the management of fisheries resources by reducing over-exploitation, based on the consumer's selection. The role of consumers in the sustainable fishery was studied by comparing the social responsibility and consumer's activity between Korea and foreign countries and international NGO groups, based on the FAO guideline. The adoption of the Marine Stewardship Council (MSC)'s eco-labelling certificate was suggested by expanding the existing environment-friendly certification system in Korea. This new system will contribute to the protection of young immature fish and spawners in coastal and offshore fisheries as well as to the international trade of seafood in terms of fish products from well-managed fisheries. It is noted that the consumer's activities in the markets as regulators will contribute to the ecosystem health and sustainability.

The demand for the study about the pollution haven activities under increasing return to scale is increasing since the trade theory under increasing return to scale has been developed. In this paper, based on Davis (1998)'s argument about home market effect, pollution haven activities under increasing return to scale is developed. The result shows that pollution haven effect can be identified with the high trade barriers. When the trade barriers are lowered, both pollution haven effect of heavy polluted industries and migration of low polluted industries are mixed together. Even the behavior under pollution haven hypothesis and that of pollution haven effects are co-existed. Therefore, to keep both environmental protection and continuous economic development, the local government of the region with high environment preservation value encourages the productivity increase of the environmental technique.

In order to manage the demand resources of project participants and to provide appropriate strategies in the virtual power plant's power trading platform for consumers or operators who want to participate in the distributed resource collective trading market, it is very important to forecast the next day's demand of individual participants and the overall system's electricity demand. This paper developed a power demand forecasting model for the next day. For the model, we used LSTM algorithm of deep learning technique in consideration of time series characteristics of power demand forecasting data, and new scheme is applied by applying one-hot encoding method to input/output values such as power demand. In the performance evaluation for comparing the general DNN with our LSTM forecasting model, both model showed 4.50 and 1.89 of root mean square error, respectively, and our LSTM model showed high prediction accuracy.

Car-sharing is a representative model of the sharing economy, and it is a service that rents or uses a car for the necessary time without owning a car. This industry is growing due to various factors such as technological advances, increasing awareness of environmental protection, and increasing demand for solving traffic congestion problems in cities. Accordingly, there is a need for a strategic approach for companies providing car-sharing services to respond quickly to market changes in order to expand market share and differentiate services. Accordingly, this study conducted a case study on open innovation activities between Gongcar and existing rental car companies, focusing on the research question "What effects do open innovation activities between car-sharing companies and existing rental car companies cause?" As a result of the study, it was confirmed that Gongcar have (1) the ability to actively respond to market fluctuations by establishing a flexible vehicle supply chain based on demand, (2) have significantly reduced growth capital expenditure (Growth Capex), and both cafe and rental car companies have (3) performed successful open innovation by improving key KPI indicators and recording financial performance. This study reveals how open innovation acts as a key business growth engine in the car-sharing industry, and its significance is found in that it empirically confirmed the successful implementation conditions of open innovation based on resource dependence theory.
