In this paper, numerical results for 3-D supersonic turbine flow have been firstly compared with the experimental results to verify results computed by $Fine^{TM}/Turbo$. It was found that $Fine^{TM}/Turbo$ can accurately predict flow characteristics within supersonic turbine. Next, an grid system for 3D turbine flow was optimized selected through grid independency test. Finally, the effect of axial gap between rotor and nozzle and chamfer angle of blade edge on the flow characteristics within 3-D supersonic turbine was analyzed with Frozen Rotor method.

ABSTRACT: The purpose of this study is to categorize and clarify rural planning system in japan. To such this study, Firstly, Existing rural plans are gathered and categorized, which are composed of related five plans. In japan, No single law deal with all aspects of rural planning and development. Rural planning and development are dealt with by a number of law and the other schemes of government. Secondly, Existing rural planning system is examined in the theory of planning process, which is planning area, establishment, execution and control of rural planning. In addition, Some implication for improving rural planning system in korea is drew.

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.
