This study is intending to look into the status of the hitherto established local governments light pollution control ordinance, and to use the ordinance status as basic data of ordinance enactment related to light pollution in time of its establishment and revision in accordance with regional characteristics of each local government for the time to come. This study conducted this research in a total of 3-phase research methods. 1) This study inquired into the direction of the research plan through the theoretical consideration and analysis of the preceding researches after setting up research objectives according to research background and purpose. 2) Targeting 11 local governments which are enforcing the hitherto established ordinance, this study surveyed the status of the light pollution control ordinance. 3) This study carried out the contents analysis of the ordinance in the method of doing a comparative analysis of each provision of the ordinance according to local governments. It's hoped that on the basis of this research, local governments across the nation, which have not yet established the same ordinance, could minimize the damage to natural eco-system due to artificial lighting by promoting the urgent ordinance establishment suited for each region, and create human-oriented light environment by modifying various disorderly lighting environment.

With it being inevitable to change the method of supervising as it is reorganized to EEZ coming out of the old concept of contamination in Korean area of the sea, it costs a lot to have good enough systems of total control for sea contamination and prevention of contamination as well as the effective marine superintendence because the governing bodies such as Ministry of Maritime Affairs and Fisheries, National Maritime Police Agency, and Authorities of Guiding Ships for Fishery, have their own source of laws and different ways to execute. In order to change such a wrong method of marine superintendence, it is necessary to conduct the merger and abolition of similar authorities with similar functions into authorities which are light but can be expected to play a major role, and to open the high-costing low-efficient organizations to make them remodel to be reborn as economical bodies. In addition to that, the maritime authorities, which are falling to incapable organizations not being able to work out any complicated tasks, have to be reborn as preventing bodies which take care of security and public peace and cut off a pollution source from sea and land.

With automobiles sharply increasing in numbers worldwide, we are faced with critical social issues such as traffic accidents, traffic jams, environmental pollution, and economic inefficiency. In response, research on ITS is promoted mainly by regions with advanced automotive industry such as the U.S., Europe, and Japan. While Korea is working on moving forward in the global market through developing and turning to global standards systems related to ASV (Advanced Safety Vehicle), the country is not fully prepared for such projects. The purpose of ACC (Adaptive Cruise Control) is to control a vehicle's longitudinal speed and distance and minimize driver workload. Such a system should be valuable in preventing accidents, as it reduces driver workload in the 21st-century world of telematics created by development of the automobile culture industry. In this light, the thesis presents a method to test and evaluate ACC system and a mathematical method to assess distance. For the proposed test and evaluation, theoretical values are tested with vehicle test and a database is acquired, by using vehicles equipped with an ACC system. Theoretical evaluation criteria for developing ACC system may be used and scenario-specific evaluation methods may find useful application through testing the formula proposed by comparing the database and mathematical method.

With automobiles sharply increasing worldwide, we are faced with serious social problems such as traffic accidents, traffic jams, environmental pollution, and economic inefficiency. In response, research on ITS is promoted mainly by regions with advanced automotive industry such as the US, Europe, and Japan. While Korea is working to get ahead to take global market through developing and turning into global standards systems related to ASV(Advanced Safety Vehicle), the country is not excellently prepared for such projects. The purpose of ACC is to control the vehicle's longitudinal speed and distance and minimize driver workload. Such a system should be useful in preventing accidents, as it reduces driver workload in the 21st-century world of telematics created by the development of automobile culture industry. In this light, the thesis presents a method to test and evaluate ACC system and a mathematical method to assess distance. Furthermore, for the proposed test and evaluation, theoretical values are tested with vehicle test and a database is acquired, by using vehicles equipped with an ACC system. We proposed the scenarios suitable for the domestic environment and conducted the actual road test. Theoretical evaluation criteria for developing ACC system may be employed and scenario-specific evaluation methods may find their useful application through testing the formula proposed by comparing the database and the mathematical method. and, many companies are expected to utilize the scenario in the developing stage of ACC, and be able to employ as a verification method by harnessing theoretical formula before a road test.
