In electro-galvanizing line to manufacture the electro-galvanized steel sheet, polishing system is required to maintain clean surface of conductor roll and to secure the quality of the steel sheet. At the same time, prediction and decision of the replacement cycle for felt material and its brush installed in the polishing system is also important because the brush is directly contacted on the conductor roll surface. In this study, the polishing system has been designed which the brush is repetitive translating according to the longitudinal direction of the conductor roll. Furthermore, the prediction on the wear-life of the felt material used for the brush is performed using the contact pressure extracted by finite element analysis. And to verify the predicted wear-life of the felt material, the experimental study is also carried out. From the comparison result between the predicted and the measured wear-life of the felt material, it is presented that the wear-life and the replacement cycle of the felt material are well predicted by considering a wear compensation factor, and the wear compensation factor is useful and reasonable.

Thanks to the popularization of golf, the population of young golfers including female players has been continuously increasing and the market specialization of golf-wear has been gradually intensifying with a growing number of new import brands in the market. This study is aimed to provide a direction to strengthen and invigorate the competitiveness of domestic golf wear brands through research on the benefits pursued by, the purchase attitudes towards local and overseas brands and the purchasing behaviors of female customers who have emerged as the newest customer group in the golf-wear market. The subjects of the research were 409 female golfers and the statistical analyses used for the study were factor analysis, cluster analysis, ANOVA, Scheffe test, and chi-square test. The results showed that there were six factors sought for golf-wear benefits: figure compensation, brand orientation, comfort, youth/fashion, maturity/conformity, and individuality. Cluster analysis showed that there were three groups of golf-wear benefits sought. Overall, the three groups were different in regard to golf involvement and golf-wear preferences. Based upon the results mentioned above, this study summarizes the key features of each group and can provide applicable suggestions for conducting strategic marketing activities.

Middle age is the time of the most important meaning in life and also the time of physical and mental change, which offers new social activities for self-development. Middle-aged women form the major consumer class in current clothing industry, but few have been performed on this so far. The researcher studied in many aspect on the clothes which middle-aged women need to wear during this period of change. Thus this study is executed to examine what benefits middle-aged women pursue in clothing attitudes and the relationship among clothing pursuit benefit and their somatotype compensation and image orientation. The research performed the theoretical study and practical study simultaneously. The subjects are 238 middle-aged women between 35 and 49 years old in September, 2004. The results of this study are as follows: 1. The attitude of women's clothing patterns in relation with image consist of two factor structures. One is the body image and the other is the appearance image. 2. As a result of researching the attitude for choosing clothes of each body group by Rohrer index, the women with gross body group take a top priority for the lower-body compensation, while the women with slim body group take a top priority for volume compensation. 3. As a result of researching the cognitive somatotype group's attitude for choosing clothes, gross body group takes a top priority for lower-body compensation and upper-body compensation. 4. As a result of researching the relationship between real somatotype and cognitive somatotype by Rohrer index, middle-aged women think of themselves as being fatter than present state. And choosing the clothes, the body misunderstanding group of women usually show that they consider more compensation than the normally body understanding group. 5. The evaluation on real somatotype, cognitive somatotype, ideal somatotype influences on the body cathexis.
