To meet recent increasing demand for electric power in large cities in Korea, and to improve reliability of the power supply. Especially, demand for electric power apparatus places great emphasis on not only function but also environmental factors. In this paper, environpolitics describes according to large capacity demand for extra high voltage underground transmission lines and high reliability of the power supply.

This study has been carried out with the purpose of coming up with suggestions for designation of domestic protection areas and improvement of their management through a comparative analysis of the systems of management of the protection areas in South Korea, Japan and China. Starting with the designation of natural reserves in 1962, South Korea has prepared legal systems for preserving ecosystems and biodiversity, while continuing to designate protected areas. As the state has so far monopolized the designation and management of all South Korean protection areas that take up 10.8% of its entire land area (as of Dec. 2011), with such persisting issues as multiple designations of one and the same area for protection, overlapping management authorities, and management of privately owned land in the protection areas. In Japan, which has protected area sizes and relevant legal systems similar to those in South Korea, the state provides the basic framework for management, while delegating most of the duties related to direct operation and management to specific municipalities. China, with an integrated administrative management of protected areas, has related government offices and municipalities responsible for the designation and management of individual protected areas. South Korea needs to provide a legally based support system that would further enhance the value of areal protection and contribute to the promotion of local economy and community.

Agriculture nonpoint pollution source is a significant contributor to water quality degradation. To establish effective water quality control policy, environpolitics establishment person must be able to estimate nonpoint source loads to lakes and streams. To meet this need for orchard area, we investigated a real rainfall runoff phenomena about it. We developed nonpoint source runoff estimation models for vineyard area that has lots of fertilizer, compost specially between agricultural areas. Data used in nonpoint source estimation model gained from real measuring runoff loads and it surveyed for two years(2008-2009 year) about vineyard. Nonpoint source runoff loads estimation models were composed of using independent variables(rainfall, storm duration time(SDT), antecedent dry weather period(ADWP), total runoff depth(TRD), average storm intensity(ASI), average runoff intensity(ARI)). Rainfall, total runoff depth and average runoff intensity among six independent variables were specially high related to nonpoint source runoff loads such as BOD, COD, TN, TP, TOC and SS. The best regression model to predict nonpoint source runoff load was Model 6 and regression factor of all water quality items except for was $R^2=0.85$.
