As the smart phone market grows rapidly, the significance of the application (app) market also increases. The purposes of this study were to identify market segments according to technological innovativeness and clothing involvement, and to compare the differences in lifestyles, benefits of fashion information app sought, and intention to use. The data were collected from smart phone users in their 10s to 30s in 2013, and a total of 292 data sets were analyzed. The findings of this study were as follows. The respondents were divided into three groups, innovative group, clothing involvement group, and passive group. Significant differences were found among three segments in terms of age, marital status, education level, and monthly income. With respect to five lifestyle factors, innovative group and clothing involvement group had higher mean scores for rational purchase, personal relationship, and personality pursuit than passive group. However, these two groups showed differences in brand pursuit factor. The benefits of the fashion information app were generated into two factors, information benefit and enjoyment benefit. Innovative group and clothing involvement group had higher values than passive group in these two factors. Finally, innovative group had the highest value on the intentionto use fashion information app. This study attempts to provide fundamental information about the potential market segment for managers or marketers developing fashion information apps.

SNCM420 steel is one of the cam shaft materials which are used in the supply unit for ship engine cam shaft. In this study the assessment of cutting behavior was conducted for the SNCM 420 steel and SM45C steel with various cutting conditions as depth of cut 0.5, 1.0, 1.5, 2.0mm and feed rate 0.1~0.3m/rev. The controlled chip was produced in feed rate 0.2, depth of cut 1.0 for SNCM420 and feed rate 0.2, depth of cut 2.0 for SM45C. There is no difference cutting force between SM45C and SNCM420 steels.

The wear and friction characteristics of cam shaft in power supply unit have been investigated as function of a driving loads and speeds. The cam shaft is a core part in ship engine. To improve the efficiency of the engine, we had tested the friction and wear of them. The wear of SM45C is more degraded up to compared with SNCM420 materials. Also the friction characteristics of SNCM420 is lower than SM45C in high loads.
