Much attention has been given recently to solve the environmental contamination in golf courses Changing to culture practice rather than chemical practice that depends on pesticides and fertilizers is a hot issue in golf courses or grasslands. Organic soil conditioners improve soil-plant envirormental conditions rich in physical properties. In this study, measuring systems to evaluate soil conditioning effects were set up for on-site purpose. After establishing the methodology for evaluating soil conditioner effects, 2 kinds of organic conditioners were rested for examination. The systems for the methodology included a set of simulating equipment for field capacity, an impact type soil column compactor, and an infiltration-percolation system. Test results using the systems showed bulk density and infiltration rate of mixed soil were decreased at highter rates of conditioner, but total porocities were increased. Increased porocities were most capillary pore space which has a positive effect on soil water potential. The systems and methodology in this study seem to have an efficiency to measure the effects of soil conditioner on site purpose.

Objectives: This study examined the impact of a smoke-free policy on indoor air quality at indoor recreation facilities by assessing $PM_{2.5}$ concentrations before and after the implementation of the new policy. Methods: Using real-time monitors, $PM_{2.5}$ concentrations were measured in 50 billiard rooms and 50 golf simulator rooms in Seoul, Korea. The characteristics of the indoor recreation facilities, smoking status, and atmospheric conditions were recorded at the same time.After the enforcement of a smoke-free policy, $PM_{2.5}$ concentrations, installation of smoking room, and smoking status were examined when the facilities were revisited. Results: Almost a half of the billiard rooms and over 80% of golf simulator rooms were located underground. Seventy percent of the billiard rooms and one hundred percent of the golf simulator rooms were equipped with a local exhaust ventilation system. After the implementation of the smoke-free policy, 46% of the billiard rooms and 20% of the golf simulator rooms newly installed a smoking room. In the billiard rooms with a newly-installed smoking room, the $PM_{2.5}$ concentrations decreased from 97.9 to $45.6{\mu}g/m^3$ after the implementation of the smoke-free policy. The same change of 29.0 to $ 26.3{\mu}g/m^3$ was not statistically significant in golf simulator rooms. Indoor $PM_{2.5}$ concentrations were correlated with outdoor $PM_{2.5}$ concentrations, number of smokers, and number of people in the room. Conclusions: The smoke-free policy for indoor recreation facilities was not effective at making the indoor spaces free from second hand smoke. Although a few billiard rooms installed a smoking room, indoor $PM_{2.5}$ concentrations were still higher than those of outdoor $PM_{2.5}$ or atmospheric $PM_{2.5}$. Stricter enforcement of the smoke-free policy should be achieved to prevent secondhand smoke exposure.

본 연구의 목적은 시간의 흐름에 따라 생성되는 사건을 매개체로 하여 골프코스를 해석하고자 하는 것이다. 골프경기를 하면서 티샷, 두 번째 샷, 피팅, 홀아웃과 같은 다양한 사건이 발생하는데, 이러한 사건들을 바탕으로 버디, 파, 보기, 더블보기와 같은 준원인에 의한 사건의 계열화가 발생한다. 그러나 이러한 사건의 계열화는 항상 예측할 수 없는 방향으로 진행된다. 이러한 예측 불가능한 사건의 발생은 공간의 특성을 변화시키는 동시에 골퍼에게는 잊을 수 없는 체험을 제공한다. 질 들뢰즈는 공간의 특성을 홈 패인 공간과 매끈한 공간으로 구분하고 있다. 홈 패인 공간이란 차원적이고 계산되어지고 중심을 가지는 원거리적 공간으로 정주민적 공간의 특성을 지니는 공간이며, 매끈한 공간은 방향적이고 탈중심적이며 촉지적인 근거리적 공간으로 유목민적 공간의 특성을 지니는 공간을 말한다. 본 연구는 이러한 매끈한 공간과 홈 패인 공간을 개념적 기준으로 하여 공간의 특성을 분석하였다. 골프코스는 본래 인공적으로 설계된 매끈한 공간의 특성을 지니고 있으나, 골프경기가 진행되면서 사건생성적인 공간으로 변모한다. 즉, 동적이고 변화무쌍하며, 스케일이 장소에 따라 가변화되는 매끈한 공간으로 탈바꿈하게 된다. 경기를 진행함에 따라 이러한 공간적 특성의 반전은 예측할 수 없는 다양한 사건을 통하여 반복된다. 또한, 경기의 주체인 골퍼는 정위-중심설정-한정-순치라는 일련의 장소만들기 과정을 통하여 골프코스와의 역동적, 유기적 맞물림을 통하여 현상학적 체험과정을 느끼게 된다.

In this study, weight carrying pattern analysis and comparison method of four foot region were suggested. We used three types of club(driver, iron7, pitching wedge). This analysis method can compare between top class golfer and beginner. And the comparison data can be used to correct the swing pose of trainee. If motion analysis system, which can measure the swing speed and instantaneous acceleration at the point of hitting a ball, is combined with this plantar foot force analysis method, new design development of golf shoes to increase comfort and ball flight distance will be available. 1. Regional change of force acting, in address, is evenly distributed on both feet. In back swing top, 76% on right foot, 75% on left foot as impact, and 86% on left foot as finish. As regional force acting, in address, pros get high marks on rare and inside of right foot and rare and outside for amateurs. In back swing top, it is higher as fore and inside of left foot, pros as rare part of right foot and amateurs as forefoot. In impact, it is higher for pros and amateurs in outside and rare part of left foot and fore and inside of right foot. In finish, for both pros and amateurs, it is higher for outside and rare parts of left foot. 2. For each club, forces are evenly distributed on both feet in address. In back swing top, the shorter a club is, the higher impact on right foot and the higher finish distribution on left foot. For all the clubs used, in each region, pros get higher on rare and inside of right foot and as amateurs on rare and outside of left foot in address. In back swing top, for all clubs, pros get higher on rare and outside of right foot as fore and outside for amateurs. In impact acting, for all clubs, rare and outside of left foot get higher. In finish, force concentrates on rarefoot. 3. On both feet force, right foot forces of amateurs is higher than those of pros in back swing top. In impact and finish, pros get higher on left foot.

In recent years, the construction of golf course has been increasing very rapidIy and serious concern is paid to its environmental consequences both in Korea and in Japan. EIA systems as a major requirements for golf course developments emerged to reduce the adverse impact of their developments in Korea as well as in Japan. This study aims to compare EIA systems, procedures and methodologies employed between Korea and Japan in order to demonstrate the success and failure of EIAs in each country. The results of this study can be summarized as follows : 1) EIAs are systematically undertaken based upon law in Korea but on regulation in Japan. 2) Public participation Isn't encouraged in the Korean EIA procedure while the Japan EIA system involves public participation. 3) Korean EISs shall be prepared after the proposed projects are approved according to the related laws and be followed by the necessary procedures, but in the carte of Japan, EISs be prepared prior to their approval . 4) ELSs shall be prepared by agencies with special expertise with respect to 7he environmental impacts (appointed by government) or the sponsoring agencies themselves in Korea whereas they be prepared by agencies proposing the projects in japan. 5) EISs both in Korea and in Japan are characterized by cliches which may be unfamiliar to reviews and the public. 6) EIAs describe the existing presence and predict and evaluate that a development work influences the present conditions. Here Japan EIA treats mainly natural - and life environment, whereas Korean EIA dose social - and economic environment. And hence in the case of Japan is undertaken more quantitative and scientific analysis, whereas in the case of Korea is less. It is suggested that the key point to impact analysis is to use the correct concepts, fomulate the comparative studies of methodologies and find the methods that suit the decision as well as which country's own circumstances.

According to a rise in leisure time thanks to a five-day workweek system, the population of golf tends to rise day by day as exercise not extreme and doing together with nature, and as a sport with high concentration degree, by virtue of people who have an interest in health care and who strive to enjoy a leisure life. This study targeted the whole male and female golfers who reside in the areas of Seoul and Gyeonggi-do and are now playing golf, carried out sampling, and finally used 485 sheets for analyzing data. The study results were as follows; First, as a result of analyzing the whole lifestyle propensity depending on golfers' gender, it was shown that, as a result of making it type by factor, a male golfer was classified into shopping intention, fashion intention, family intention and tradition intention, and a female golfer was divided into shopping intention, fashion intention, family intention and man-and-woman equality intention. Second, as a result of analyzing a characteristic of gender depending on the standard of selecting goods, it showed the difference between genders as for the standard of selecting goods in case of purchasing golfwear, and it showed the difference in style/design, physique fitness, wearing of a famous golfer, convenience of laundry and management, and functionality, and male golfers were shown to select after seeing the clothes which a famous golfer did wear, compared to female golfers. Also, it could be seen that there was difference depending on the standard of selecting goods and the purchasing propensity in case of buying golfwear.
