The economic reform in China since 1978 has been increasingly sped up and deepened. The recent development of private enterprises, especially, has significant economic and political implications, whereas its regional differentiation has considerable impacts on both the development potential of certain regions and overall regional growth pattern. This study aims to understand the regional pattern of private enterprise growth as well as the institutional change which has structured the growth process. The development of private enterprises turned out to be closely tied to the marketization strategy of dual-track system and policy needs to reduce the unemployment level in both urban and 겨ral China. The regional pattern of the private enterprise growth can be characterized as ever-increasing spatial differentiation. Based on the basic statistical analysis results, it is argued that the private enterprise growth is closed related with the marketization level of the regional economy. Therefore, the strategy of developing private sector will be more important in shaping the regional development path as well as potential.

The quantum logic was introduced by G. Birkhoff and 1. von Neumann in order to study projections of a Hilbert space for a formulation of quantum mechanics, and Husimi proposed orthomodular law and orthomodular lattices to complement the quantum logic. Abott introduced orthoimplication algebras and its properties to investigate an implication of orthomodular lattice. The commuting relation is an important property on orthomodular lattice which is related with the distributive law and the modular law, etc. In this paper, we define a binary operation on orthoimplication algebra and the greatest lower bound by using this operation and research some properties of this operation. Also we define a homomorphism and characterize the commuting relation of orthoimplication algebra by the homomorphism.

This essay begins with the following questions; "What is a fundamental source of media power?" and "How can the media power dominate market?". This essay aims at answering the questions. I made my selection of countries such as Venezuela, Italy and UK for this article with a political economic approach. This analysis found evidence that an enormous conglomerate ownership, and alliance or convergence between media and political power are two fundamental source of the media power. With the integration of newspaper and television the media monopoly increased their supplies and political influences as I have shown. Despite the growing threat of media monopoly power to democracy and public interest, in recent years, governments worldwide have chosen to ease regulations.
