This study simulated the range of golf ball with different projection angles using a drive swing condition. For the simulation purpose, the differential equation of dynamics was induced by using Bernoulli's principle and average back spin frequency, instant velocity, and dimple of golf ball from amateur group, professional group, and Tiger Woods were chosen as the initial condition. The study result indicated that lift coefficient($C_{lift}$) relative to drag coefficient ($C_d$), 0.3 of differential equation was applied differently in terms of back spin Sequency, and when $C_{lift}$ was 0.4 for amateur, 0.5 for professional, and 0.7 for Tiger Woods the projection ranges of ball were closely matched with initial condition. With selected $C_{lift}$ and back spin frequency of initial condition, the ranges with different projection angle was measured as 193m ($13-17^{\circ}$) for amateur, 240m ($9-13^{\circ}$), professional and 273m ($9^{\circ}$)Tiger Woods, respectively. For the range in terms of back spin frequency and projection angle, the amateur group indicated relatively high spin frequency (70 RPS) and showed the maximal range (195m) with $13^{\circ}$ of projection angle. The tendency of longer range with higher projection angle was also found under the different conditions of spin frequency in this group. The professional group showed their maximal range (245m) with conditions of 60RPS of spin frequency and $9^{\circ}$ of projection angle. Their range was decreased dramatically when the spin frequency was reduced to 40-50 RPS. For Tiger Woods, the maximal range was found with 40RPS of spin frequency and the range was decreased notably when the spin frequency was above 40RPS.

The purpose of this study is to comprehend the contemporary sports star fashion and to contemplate aesthetic characteristics of sports star fashion, thereby to establish the styles of sports star fashion. For such purposes, this study first examines aesthetic characteristics of sports fashion and star fashion based on previous studies, in order to analyze aesthetic characteristics of sports star fashion, and conducts a case study by analyzing photographic materials of fashion styles of well-known male sports stars such as the English soccer player David Beckham and American golf player Tiger Woods. The result of this study is as follows: the aesthetic characteristics of the contemporary sports star fashion are virility, functionality, sensuality and deconstruction. (1) Virility emphasizes manly features by displaying trained and disciplined body. (2) Functionality is expressed through structural simplicity and temperance of decoration. High-tech textiles and fibers are favored in order to fit in comfortable bodily movement for the heavy exercises. (3) Sensuality, as an expression of indulgence of sexual pleasure, is expressed through bodily exposure. Lastly, (4) deconstruction, which means destroying existed boundaries of cultural categories, is shown as co-existence of design elements from different times and places, stereotypes and sensibilities. Virility and functionality are prominent characteristics expressed in sports uniforms and training costumes. Sensuality and deconstruction are shown in daily fashion and formal dress outside the sports field.

Purpose: This study sought to examine the symbolization of brand identity in Nike golf advertisements and to provide implications for sporting goods ads. Research design, data, and methodology: The study employed Socher's semiotic theory to analyze characteristics embedded in Nike video advertisements. In specific, the study selected 'No cup is safe' among Nike video ads and analyzed structures of ad message and presented metaphors of ad messages. Results: As a study on the semiotic analysis of communication by case, this study investigated how the brand identity pursued by Nike in the advertisement is symbolized by identifying the signifier and signified in the advertisement. As a result of the study, it was possible to segment and analyze a total of 8 advertisement scenes, from the most important tee shot in golf, setting the aiming, sending to the center of the fairway, and applying the general situation of ball in and hole out to the cases of Tiger Woods and McIlroy, thereby helping the general public. Conclusions: Summary of above results showed that it was also conveying the message of metaphor and metonymy that 'I can be like Tiger Woods and McIlroy' by using Nike golf products. Further implications were discussed.
