By development of renewable energy and more efficient facilities in an increasingly deregulated electricity market, the operation cost of distributed generation (DG) is becoming more competitive. International environmental regulations of the leaking carbon become effective to reinforce global efforts for a low-carbon paradigm. Through increased DG, operators of DG are able to supply electric power to customers who are connected directly to DG as well as loads that are connected to entire network. In this situation, a community energy system (CES) with DGs is a new participant in the energy market. DG's purchase price from the market is different from the DG's sales price to the market due to transmission service charges and other costs. Therefore, CES who owns DGs has to control the produced electric power per hourly period in order to maximize profit. Considering the international environment regulations, CE will be an important element to decide the marginal cost of generators as well as the classified fuel unit cost and unit's efficiency. This paper introduces the optimal operation of CES's DG connected to the distribution network considering CE. The purpose of optimization is to maximize the profit of CES. A Particle Swarm Optimization (PSO) will be used to solve this complicated problem. The optimal operation of DG represented in this paper would guide CES and system operators in determining the decision making criteria.

The implementation of an place-based rural policy requires changes in the intra-governmental relations and between the public and private sectors and civil society. Over the past decades, Japan has been increasingly devolving and decentralizing public responsibilities and resources to sub-national government levels. There is assumption that such transfers produce more efficiency in terms of public management and create better conditions for economic development. At the same time, these transfer respond to new expectations of citizens and civil society to participate more closely in the democratic decision-making process. Coordination is also needed at the local level to integrate sectoral approaches, to involve private partners and to achieve the appropriate geographic scale. Local public and private actors join a partnership and pool knowledge and resources. This type of local partnership is characterized by the participation of different actors, including municipalities, sub-regional government institution and development agencies. The participation of private actors(private firms, cooperatives, associations, non-profit organizations, farm organizations, other categories organizations, etc,) is also important.

Some spread-effects and their dynamics accruing to regional community from the new location of large firms would be an interesting theme in economic geography On the assumption that all firms not only should. have cooperative relations with their regional communities but also try to realize such cooperations in case of locating their facilities, some rationale for their philanthropic activities will be discussed in this paper. The focus of this paper is on the community contributions or philanthropy which are executed as the non-profit motivated activities of firms. Why and how should firms respond to the growing requirements of their communities, and what type of philanthropic activities could be good for their social behavioral contexts are the questions to be solved in this study. It is possible to get some guidelines of a firm's philanthropy through the comparisons on the practices in the three largest firm.5: Kodak. Dupont, and POSCO.

Recently as return farmers has been increased rapidly, the introduction of a system of rental housing is being considerated in order to induce regional fixation. It was examined organizational management, business scope of rural type rental housing, management role, through the analysis about the management realities of the business of similar form Rural-Fishing New Town project. Jangseonggun and Hwasungun have maneged rental housing 280ho in Rural-Fishing New Town project. It is large village among Rural Rental Housing. And these counties have organized the complex on a large scale among the rental housing. Local governments have managed and operated directly, also these governments have two different methods for the co-management, and the way of making payment. Rental housing management services are divided into rental management, housing management, tenant management. Rental management services such as residents of recruitment, tenants and retreat, rent collection and the storage, management and leasing promotion of the cantilever, surveys of residents. Housing management services such as check of various facilities, maintenance and maintenance work, security and cleaning and daily facility management. Tenant management is life management in connection with housing welfare. In the rural type of rental housing, there are few cases to operate a management office. It is often supplied by rental housing to buy a house or vacant land within the existing village. In this case, by utilizing community facilities within the existing village instead of establishment of extra facilities,It doesn't need to make payment for maintenance fee. In the smaller complex than No. 20, it is self-managed by the tenants in order to reduce the administrative costs and specify the necessary municipal manager. Organization form can be maneged directly from local governments and part of for the management of the building can be employed a mixed management system to delegate management to private organizations such as non-profit organizations or neighborhood association. Tenant management helps people who move in a rental house live on stable circumstance in there area by connection with the program of life support.
