In this research, the magnetic abrasive finishing process using (Nd-Fe-B) permanent magnet was applied to confirm the performance and to find the optimum conditions. The STS304 bar was used as the specimen in this experiment. In order to confirm the performance of magnetic abrasive finishing process, the surface roughness (Ra) and diameter reduction were measured when the specimens were processed under the conditions of rotational speeds, frequencies, and magnetic pole shapes. The rotational speeds were varied at 8000rpm, 15000rpm, 20000rpm, and 25000rpm. And the frequencies were changed to 0Hz, 4Hz and 10Hz. Also the shapes of the magnetic pole were changed to flat edge, sharp edge and round edge. It can be concluded that the surface roughness (Ra) and diameter reduction were found to be the best at 25000rpm, 4Hz, flat edge.

This study aims to investigate which difference exists in emotional reaction induced by advertising and attitude toward advertising depending on the types of advertising appeals(emotional appeal/rational appeal). And this study tries to reveal the effects of emotional reaction about bottled water advertising on attitude toward advertising and purchase intentions. Total 300 questionnaires were distributed and 260 were returned usable. Subjects were exposed to print ads of two versions of emotional appeal and rational appeal. The results of this study were as follows : First, the consumer emotional reaction of bottled water advertising by the types of appeal showed statistically significant difference. Except for emotional reaction of ‘domination’, emotional appeal advertising was more higher than rational advertising for ‘pleasure’ and ‘arousal’ feeling. Second, there existed the significant differences between rational appeal and emotional appeal to the attitude toward the advertising. Third, the consumer emotional reaction evoked by bottled water advertising had a significant influence on the attitude toward advertising. Fourth, advertising attitude had a positive influence on purchase intention.
