This study used the questionnaire method to find out the golf factor comparison and purchase inclination according the golfers' demographic characteristics. The golf factor comparison according to the Gyeongnam golfers' demographic characteristics was performed with cross analysis and $X^2$ verification, the purchase inclination with T verification and analysis of variance. And the Golfs' factor relation according to total income was performed with cross analysis and $x^2-test$. The golfers' demographic characteristics showed a significant difference in gender, educational background and occupations. The participation purposes of playing golf for men were as a hobby, relations and business. And the participation purposes of playing golf for women were as a hobby and health. The higher age was, the more the golf career was for both men and women. In the factor of marital status, unmarried people play for a hobby and married people play for better relations and business. In the factor of gross income, male golfers varied in the gold career and monthly playing times. Female golfers varied in the golf career. Regardless of gender, the higher the income was, the more the golf career was. In the comparison of buy behavior according to the golfers' demographic characteristics, male golfers showed a significant difference in ostentation and fashion according to the monthly purchase of golf-wear. The group that spends more on the monthly purchase of golf wear was higher than the group that spends less on the monthly purchase of golf wear. Unmarried golfers showed more ostentation tendency that married golfers.

This paper studies the effect of pad at initial stage and wear during braking on the dynamic contact pressure distribution. Wear is influenced by variable factor (contact pressure, sliding speed, radius, temperature) during dynamic braking and variation in contact pressure distribution. Many researchers have conducted complex eigenvalue analysis considering wear characteristic with Lim and Ashby wear map. The conventional analysis method is assumed the pad has smooth and flat surfaces. The purpose of this paper is to validate that wear rate induced by braking is considered for the precise squeal prediction. After obtaining pad wear from experiment, it is incorporated with FE model of brake system. Finally, the comparisons in fugitive nature of squeal will be carried out between the complex eigenvalue analysis and noise dynamometer experiment.

This study investigates the effects of fashion innovativeness and utilization on the price perception of formal wear and climbing wear as well as gender differences on price perception and the relationship of the variables. Price perception measurements were based on reference price and reservation price; subsequently, a premium price ratio was calculated based on the measured prices. A survey that involved male and female adult consumers was conducted in Daegu in August 2011. A total of 321 responses were analyzed using descriptive statistics, factor analysis, reliability analysis, correlations and independent sample t-test. Two factors of fashion innovativeness were derived and named as unique-oriented innovativeness and change-oriented innovativeness. The utilization of formal wear and climbing wear was higher in the male group versus the female group. Reference price and reservation price were identified similar to the actual consumer purchasing prices reported in previous studies. Male consumers showed a tendency in price perception in accordance with the utilization. The change-oriented innovativeness of the female group led to a positive relationship with the perceived price of climbing jackets.

건조 및 다습한 대기의 무윤활 또는 액체 윤활, 미끄럼 속도 그리고 온도 등 여러 조건 하에서 SiC-강 미끄럼 시 SiC가 나타내는 마모거동에 대하여 조사하였다. 또 SiC의 제조공정이 SiC 마모에 미치는 영향도 미끄럼 속도를 달리하면서 고찰하였다. 무윤활 미끄럼 시 대기 습도는 일종의 윤활제 역할을 하며, 특히 대기가 매우 건조한 조건 하에서 미끄럼 속도는 마모에 큰 영향을 미친다. 그리고 SiC의 제조공정 및 재료표면의 거칠기는 미끄럼 속도의 크기여하에 따라 상이한 마모거동을 초래한다. 특히 온도는 마모를 심화시키는 요인이어서 윤활 미끄럼 조건 하에서도 마모를 크게 가속한다.
