The purpose of this research is to analysis the swing of driver used by professional golfers during on-season. In order to collect on-season driver swings of research objects, which are three KPGA(Korean Professional Golfer Association) professional golfers, measurements were carried out right after the last game of a season. The analysis range was set to down-swing point while analysis was conducted to after-impact, release point. As a result, systematic process between leading segments of the previous precise kinematic analysis research seems to turn up the same. However, there were different results compared to the preceding research. All three testers expressed adduction of left hand which could not be described with forming cocking angle, in consequence, adduction of left hand does not have a big effect on formation of cocking. Moreover, chest movement right before the impact; which was emphasized in previous research, the direction was not opposite but the same with the ball.

At the dawn of a new digital era, people's way of spending their leisure time and leisure activity preferences changed. Accordingly, Leisure culture is in the midst of change, such as watching movie and performance, enjoy golf etc. Due to its nature as an interactive medium, the digital game offers uniquely different approaches to the leisure activity. Leisure as state of mind is much more subjective in that it considers the individual's perception of an activity. In that regard, we used the digital games for leisure activity. Digital games are powerful environments for fun, including functional nature. For that reason digital leisure culture keep creative evolving.

In this research, to identify the degree of preference and participation in leisure sports, over 19-year-old adults living in the capital region were collected as subjects, and among them, 250 persons were chosen by purposive sampling method. Using SPSSWIN 16.0, I analyzed the collected data by reliability analysis, paired sample t-test, PPA(preference performance analysis) method. The conclusion is the following. First, the first quadrant showed wind surfing, skins-cuba, water-ski, and yacht, and as a result of this, it is necessary to improve the degree of participation in this field, the second quadrant showed golf, racketball snow board, ski, fishing, and climbing, and these field need to specific attention to maintain continuous attention, for they have a great deal of attendance, the third quadrant, showed water sleigh, cart, balloon, sky-diving, orienteering, hang gliding, model plane, and survival game. As the degree of preference and participation in these sports is low, it is recommended that more effort should be made for these sports. Finally, in the forth quadrant, there are tracking, mountain bike, inline skates, rafting, and cycling. As it's the participation is high, while that of preference is low, it is important to maintain the policy of the participation in leisure sports. Sencondly, the degree of preference and participation in leisure sport activicties acording to socio demographic characteristics differentiate.

Using SPSSWIN 16.0, I analyzed the collected data by Reliability Analysis, Paired Sample T-Test, and IP A method. The conclusion is the following. First, the first quadrant showed skins-cuba, water-ski, wind surfing, and clay-pigeon shooting, and as a result of this, it is necessary to improve the degree of participation in this field. Secondly, the second quadrant showed golf, snow board, ski, fishing, and climbing, and these field need to specific attention to maintain continuous attention, for they have a great deal of attendance. Thirdly, in the third quadrant, there are water sleigh, cart, balloon, sky-diving, orienteering, hang gliding, model plane, and survival game. As the degree of preference and participation in these sports is low, it is recommended that more effort should be made for these sports. Finally, in the forth quadrant, there are tracking, mountain bike, inline skates, rafting, and cycling. As it's the participation is high, while that of preference is low, it is important to maintain the policy of the participation in leisure sports. In conclusion, for the sports which is preferred that is difficult to join right now, most of all, it is necessary that we should pay attention to and invest the social infrastructure in which main items cannot be joined now.
