Ulsan made its contributions to modern Korea as an industrial city. In the 1960s, Ulsan was appointed as a special industrial zone. After that, industrial complexes were built without environmental considerations so Ulsan was once called “the polluted city”. However, in the early 2000s, the main concern of Ulsan’s policies was gradually shifted from the economic growth to the environmental issues. In order to enhance the environmental quality and to make the Ulsan more environmentally friendly eco-city where human and nature coexist, Ulsan city declared “The Eco-polis Ulsan” in 2004 based on “The Master Plan for Eco-polis Ulsan” which included the eco-industrial park as an action plan. This study aims at defining the concepts of eco-city and policies to build Ulsan-style eco-city as environmentally friendly city and proposing Ulsan as a role model to cities and towns of developing countries. In addition, Ulsan’s EIP project which will be implemented for 15 years from 2005, is elaborated including regulatory issues and technologies to be applied.

This study conducted a basic experiment to build vibration power generation system that has no limit of location to install, has consistent generation all the time regardless of weather changes, and forecast power supply. The vibration power generation system applies vibration energy occurring from cars driving on the bridge to infrastructure facilities by using Faraday's law and changing into electric energy. As a basic experiment study to build the vibration power generation system infra, this study suggested a non-powered self-generator and analyzed a relationship with electromotive force of vibration energy and the vibration generator through analysis of dynamic characteristics of the vibration generator and the interior experiment in order to lead and verify the formula generating electromotive force.
