The purpose of this study was to develop an auxiliary device useful for promoting continued participation in the golf among young golfers and female beginner-level golfers who were gradually increasing in number but often losing interest in the golf and gave up playing golf due to difficulty with posture, boredom from golf itself, slow improvement of skill, etc., in the process of learning the golf. For that, a hardware device fitted with various sensors was attached to the lower part of golf club grip to develop a platform capable of collecting and transmitting the data on each golfer's swing posture, driving distance, etc. If a smartphone app, which can analyze and store those data, is developed and synchronized, each golfer's postures can be identified and golfers can correct the posture on their own. Moreover, the smartphone app provides the contents for self-comparison and comparison with others and will be able to infuse the beginner-level golfers with internal motivation for continued participation in the golfing exercise if the game-type elements are added.

The purpose of this study was to suggest a direction for golfwear design targeting young female golfers, based on the analysis of their preference of recent sportswear trend. Total 197 respondents, female golfers, were sampled for data gathering, who were asked to answer to the self-report questionnaire with the stimuli of five trendy golfwear styles [i.e., representing recent sportswear trend]. In summary, the results of this study were as follows: 1) The female golfers showed significant difference in their preference of recent sportswear-trend sues, according to their age or marital status. 2) Among the five trendy styles, each of which corresponded to five themes in 2002 S/S sportswear trend, the style of "Retro Chic", a type of retrospective trend theme, was most favored. 3) The female golfers in their twenties residing in Kangnam, were found to have ① relatively higher fashion leadership, and ② higher preference of maximal and kitsch trends, when compared with the rest of the respondents. 4) The most influential design elements in each trendy style, dominating the golfers' preference, varied with the feature of trend themes. 5) Based on the analysis of the young female golfers′ preferences of recent sportswear trend, a direction for golfwear design were suggested.

It has been reported that there are many cases of chronic shoulder injuries of golf players, however acute injuries at dominant tide are relatively rare. In this paper, we show a case of acute rotator cuff tears at dominant side due to bad swing in middle-aged woman. We suggest that golfers should be cautious with playing at winter to prevent acute rotator cuff tears by starting with a warm-up and correcting faulty swings.

This study was to investigate gender differences in muscle activities on tibialis anterior muscle, gastrocnemius and vastus medialis obliqus and outside and prime mover, antagonist and assistance mover during golf drive swing by electromyography. Ten healthy professional golfers (KPGA(n)=5, KLPGA(n)=5) volunteered in this experiment. All statistical analyses were performed using SPSS. Statistical differences were assess using t-test (p<.05). The conclusion of this study was as following. Muscle dislocation of differences, according to gender, was the highest in case of males in right side of gastrocnemius with the section from the address to the backswing of top and was the highest in case of females in tibialis anterior muscle. Results also show that prime mover was left side of low muscle in case of male with all the sections and situations and is right side low muscle in case of female. These results were significant differences. In case of males, it was though that primer mover was left side of tibialis anterior muscle with moving weight from backswing of top till the address section. In case of females, primer movers were right side of vastus medialis obliqus and tibialis anterior muscle with pushing action form the right knee to the left knee. Therefore, if they try to do the training be able to development right side of vastus medialis obliqus and tibialis anterior muscle in case of females and left side of vastus medialis obliqus and tibialis anterior muscle in case of males, it is consider that golfers' distance and direction will get better.

The purpose of this study is to research on changes of body surface according to golf movements in designs of golf slacks pattern and reflect it to designs of golf slacks pattern to enhance adaptability. For the first stage of this study, length of body surface was analyzed by using 3D body shape. In second stage, analysis of wearing test of golf slacks is performed to extract major pattern design factor of golf slacks and then research patterns were designed. In third stage, 4 differently designed 1st, 2nd slacks were used for analysis of 3D Clothing air volume. The results of this research is as follow. The variation rate of body surface length according to golf swing posture resulted the longest on back swing posture and follow through posture. Waist circumference-omphalion, thigh and ankle circumference increased more than 10% of body surface during golf swing. Front waist circumference-omphalion, right waist to hip length, left waist to hip length and right back center length were decreased more than 10%. As a result of analysis on measurements of 1st slacks pattern design, waist front center getting in values, waist front center going down value, front hip width, and front crotch extension had similar industrial pattern design. Back center line angle, back crotch extension, and knee center point~back waist center point had significant differences. The designs and ease proposed for golf slacks pattern in this study are waist circumference 75.5 cm(1.8 cm, 2.38%), hip circumference 95 cm(2 cm, 2.11%), crotch length(front: -0.8 cm, -1.25%; rear: -1.8 cm, -2.83%), slacks length 96c m, gradient of C.B.L $10^{\circ}$, crotch extension (back 9.2~10.4 cm, front 3.2 cm).

The purpose of this study is to develop a program that computes the position of the instantaneous center of rotation while an object moves in a circular motion. For this study, a mathematical algorithm was developed and implemented on the experimental data. Data for pitching (40m carry) and putting (4m) strokes were obtained from a skilled female golfer. A computer program (Centering 1.0) calculated the experimental data and found the radius of the instantaneous center of rotation. When the data were taken broadly, the program produced an error distance of radius. When the data were divided gradually, the program produced a very close instantaneous center of rotation. On comparing pitching and putting strokes, putting was found to have a greater radius than pitching. The instantaneous centers of rotation of putting were not in the golfer's body rather, they were 3m away from the club head. The Centering 1.0 program can calculate the instantaneous center of rotation with at least three sets of experimental data.
