  • The purpose of this study was to investigate the relationships between life style and clothing purchase intention and purchase criteria in internet shopping-mall of male and female consumers. The subjects were 275 internet users (male: 164, female: 111). The results of the study were as follows. Five factors of life style derived by factor analysis:'Digital Orientation','Economy Orientation','Positive Activity','Fun Orientation', and'Home Orientation'. The dress types to be based on the purchase intention in internet shopping-mall was classified into four dimensions by factor analysis: Casual Wears & Single Item Clothes','Formal Wears','Miscellaneous Goods', and'Underwears & Night Clothes'. Internet users showed relatively high purchase intention in casual wears & single item clothes and miscellaneous goods. Clothing purchase intention in internet shopping correlated significantly with home orientation in males, and with digital orientation in females. Subjects high in fun orientation placed importance on design as clothing purchase criteria. Males high in positive activity placed importance on price, color, sewing, brand, and wearing appearance. Females high in digital orientation believed design, color, material, refundment condition, and fashionability were important as purchase criteria. The level of digital orientation of dress purchasers in internet shopping-mall was higher than that of non-purchasers in case of males, and that of fun orientation was higher than that of non-purchasers in case of females. The present findings suggest that life style such as digital orientation and home orientation appeared to be important in predicting the clothing purchase intention in internet shopping mall.

  • We develop a proto-model of an off-axis reflective telescope for infrared wide-field observations based on the design of Schwarzschild-Chang type telescope. With only two mirrors, this design achieves an entrance pupil diameter of 50 mm and an effective focal length of 100 mm. We can apply this design to a mid-infrared telescope with a field of view of $8^{\circ}{\times}8^{\circ}$. In spite of the substantial advantages of off-axis telescopes in the infrared compared to refractive or on-axis reflective telescopes, it is known to be difficult to align the mirrors in off-axis systems because of their asymmetric structures. Off-axis mirrors of our telescope are manufactured at the Korea Basic Science Institute (KBSI). We analyze the fabricated mirror surfaces by fitting polynomial functions to the measured data. We accomplish alignment of this two-mirror off-axis system using a ray tracing method. A simple imaging test is performed to compare a pinhole image with a simulated prediction.
