Information is increasing continuously in on-line, it is real condition that inaccurate informations are mass-produced but effort to keep accuracy of these informations is lacking. Already, research about government official of information in World Wide Web is consisting of various method and viewpoint, but problem for the importance of correct information offer and offer of mistake information in World Wide Web about specification target and administration way presentation are no research reward yet and system that can keep accuracy of information is not equiped properly. ss and accuracy whether mistake information in harbor and bay connection web site's administration influences how in authoritativeness security of site and present condition information of harbor and bay and operation information. In this study, we wish to present administration way about mistake informations that is required that recognize problem of mistake information and the administration's importance in on-line in this research, and supply phenomenon information in Web site. We made the right definition about mistake of information through priority literature investigation and virtued research for this, and sorted mistake information in type. And we investigated Pusan port connection information and offered present condition in on-line and research on actual state of mistake information offer and analysis. Reflecting type and special quality of examined mistake informations, We want to make people recognize the importance af freshness and accuracy whether mistake information in harbor and bay connection web site's administration influences how in authoritativeness security of site and present condition information of harbor and bay and operation information.

As a city and industries are developed rapidly, a traffic accident and congestion take places on the road link become serious and it can be a large problem of the society in the future. Especially, most of the traffic accidents on the signalized intersection are caused by the human factor, vehicle and environmental factor mutually. The relation of the traffic accident and volume is acting on the outbreak of the traffic accident and the mistake of driver altogether as a major cause. The purpose of this paper is to develop a model for the forecasting of the traffic accident and to use research data gained to predict many traffic accidents. The data of this study were used with real one of the 73 areas of the four-legged signalized intersection in Kwang-ju city from 1996 to 1998 for three years to develop a model for the forecasting of the traffic accident. The statistical methods used in this paper are the principal component, regression and correlation analysis. We studied accident models to find out useful data from the statistics method and applied the data to the different area of the Choun-La province for the verification of the model. So, the result of this paper showed a reasonable model for the forecasting or the traffic accident and possibility of the model for simulating on real case. Finally, This study would be made of a study continually for the safe design and plan for the four-legged signalized intersection.
