To access the effect of binder ingredients on friction characteristics of brake pad material, five kinds of specimens with different phenolic resins were prepared. Binder materials used in the study are modified phenolic resin containing the same amount of Acrylic, Xylok, Silicone, Epoxy and Straight phenolic resin, respectively, while keeping other ingredients, such as fibers, lubricants, abrasives, fillers the same. The friction materials were tested by 1/5 scale brake dynamometer, and the transfer film formed on the rotor during the abrasive test of respective specimen was observed by SEM.<br/> Effectiveness friction stability increased with increase in brake deceleration at velocity of 130㎞/h for all the specimen studied. For all the specimens under study, the friction coefficient decreased with increase in brake deceleration, especially at high velocity such as 130㎞/h. In fade & recovery test, specimen containing Straight phenolic resin showed excellent fade resistance, while specimens containing Acrylic, Silicone showed excellent recovery resistance. The friction stability was the best for specimen containing Straight phenolic resin, but the worst for specimen containing silicone.

This study focused Southern Eastsea area(Donghae and Samcheok) in regionally. This area has many regional development difficulties, and has lower development level than Northern Eastsea area. The purpose of this study is to explore the residents` agree attitude on the marine sport tourism the study surveyed 467 subjects and processed the result by using SPSS. For statistical analysis. As a result of this analysis, The residents` attitude on the marine sport tourism is very strong and firm. Their collected opinions are as follows. First, The potentiality of marine sport tourism resources are sufficient, such as clean sea, famous beaches and long use term. Second, The regional infrastructures are well equipped, for example touism facilities, accessibility and resident`s strong will for marine sport tourism. Third, it is needed trying to develop the marine space for sport tourism, events and marine resort. So This area must try to attain regional development through Marine sport tourism.
