The improvement of safety and health education method in construction site was investigated through the survey for workers and delphi technique. The results of preliminary survey done for workers were analyzed using the multi variance analyses, and the questionnaires for delphi survey were composed based on the results of preliminary survey. Finally, the participatory safety and health education method was suggested. The result showed that most of workers were very interested in accident prevention and health. On the contrary, they did not actively participate in safety activities in sites including safety and health education. In order to improve workers' levels of safety consciousness and prevent the construction accident, the participatory safety and health education method that construction workers directly examine and give presentations about accident causes and measures was suggested and verified by tests. One-way instructor-led safety and health education used widely and participatory safety and health education with workers were carried out by dividing participants into two groups. After education, the examination is done for two groups. The test results found that the average score of safety consciousness of the worker group that received participatory safety education was higher than that of the work group that received instructor-led safety education. And the Delphi technique utilizing experts was analyzed that participatory safety education has a great effect on improvement of workers' level of safety consciousness.

This research is the first research on developing the speed limit select model and also it is the result of the research on the importance of each element and consideration factors when selecting the speed limit. For the consideration factor discrimination and calculation of the importance, the delphi method and AHP method was used. The delphi survey was processed through third round survey, 5 high consideration factor(Level 1) and 23 low consideration factor(Level 2) was discriminated. During the process of the third delphi survey, when the CVR cost was in the range between 0.4~1.0 it was treated as the consideration factor when selecting the speed limit and less than 0.4 cost was eliminated. In the process of the second delphi survey, 33 consideration factors were discriminated but was reordered into 23 categories through the third survey. Based on the 23 categories earned through the third delphi analysis, the AHP survey was processed. The result of the AHP survey was that out of the importance of the 5 high consideration factor(Level 1), the traffic condition was evaluated as the number one factor and the vessel condition, waterway condition, environment condition, supporting condition and etc. conditions were evaluated following the traffic condition. Out of the 23 low consideration factor(Level 2) consideration, the visibility was evaluated to be the first important and the performance of the vessel steering, objective factors within the harbor, amount of traffic and density, distance between the passing vessel, speed of the steering capacity and tidal current were the following evaluated factors.
