The purpose of this study is to investigate the effects of badminton exercise program on fundamental motor skills of teen-aged peoples with developmental disabilities. For this purpose, exercise group (n = 8) and control group (n = 4) were selected for the developmental disabilities aged 10-18 years including intellectual disabilities and autistic disorder. Two times a week, a 50-minute badminton exercise program was conducted for 10 weeks, and fundamental motor skills before and after the program were measured with TGMD-2. The results showed that the control group showed no significant changes in the overall score, locomotor skill, and object control skill, while the exercise group showed significant improvement in overall score, locomotor skill, and object control skill. In addition, all skills of object control skill(striking a stationary ball, catch, stationary dribble, kick, overhand throw, underhand roll) and 3 skills of locomotor skill(run, hop, horizontal jump) were significantly improved in the exercise group. In conclusion, the badminton exercise program had a positive effect on the overall basic motor skills of teen-aged peoples with developmental disabilities and confirmed that badminton was a proper program for children and adolescents with developmental disabilities. In the future, appropriate physical activity program should be actively developed to promote participation of sports and improve motor skills for a wide range of people with disabilities.

우리나라 콜시장에서의 유동성 효과: 공개시장조작 자료를 이용한 분석

권태용 ( Tae Yong Kwon ),강영관 ( Young Kwan Kang ) 한국금융학회 2008 금융연구 Vol.22 No.1

본 논문에서는 2006년 1월 9일~2007년 10월 22일 동안의 콜금리와 한국은행의 일별 지급준비금 자료를 이용하여 우리나라 콜시장에서의 유동성 효과를 분석하였다. EGARCH 모형을 이용한 분석결과는 다음과 같다. 첫째, 우리나라에서는 지급준비금 적립 마감 1~4일을 제외하고는 지준적립기간 중의 대부분의 날에서 유동성 효과가 발견되지 않았다. 특히 미국이나 일본과 달리 지준마감일에 유동성 효과가 크지 않았는데, 이는 한국은행이 과거 지준마감일에 예금은행의 지준과부족을 시장금리와 큰 차이가 없는 금리수준에서 해소해 주던 유동성 조절 관행 때문이라고 판단된다. 둘째, 2006년 11월 23일 지준율 인상 발표 이후 유동성 효과가 그 이전 기간 보다 커졌다. 이는 한국은행의 공개시장조작이 지준율 인상 발표 이후에는 시장개입 빈도를 줄이고 지준마감일에는 시장금리보다 높거나 낮은 금리로 지준과부족을 해소하는 방식으로 변경된 데 기인하는 것으로 보인다. 셋째, 한국은행의 공개시장조작이나 외생적 요인에 의한 지급준비금 변동에 대하여 현행 통화정책 운용목표인 콜금리보다 국내은행의 콜차입금리가 더 민감하게 반응하는 것으로 나타났다. 이는 현행 운용목표인 콜금리가 은행 뿐 아니라 지준 적립의무가 없는 제2금융권의 거래량과 거래금리까지 가중평균하기 때문인 것으로 분석된다. 넷째, 지급준비금의 증가와 감소가 각각 콜금리에 미치는 효과가 비대칭적이었는데 이는 은행들이 지급준비금이 부족할 때 처할 수 있는 평판 손상(stigma)을 회피하기 때문인 것으로 보인다. There seems to be a consensus among financial market participants in Korea that as the overnight call rate has been almost fixed at the target level, regardless of liquidity supply and demand conditions in the money market, its functions of market information signaling and liquidity allocation have greatly weakened. Also, restricted volatility of the call rate has led to an over-concentration of short-term funds in the overnight call market and the drying-up of term transactions in the money market. Accordingly, the transmission channel running from the call rate to short-term interest rates and long-term interest rates has not been able to function properly. Considering the drawbacks in the call rate targeting framework, the Bank of Korea (BOK) has recently reformed its monetary policy operational framework. This reform includes the change of the policy rate from the call rate to the BOK`s Base Rate applied to transactions between it and financial institutions, the regularization of open market operations and the introduction of standing facilities. In order to empirically verify this consensus by estimating the liquidity effect in the Korean call market, we use the daily aggregate level of reserves calculated by the Bank of Korea while preparing open market operations during January 2006~October 2007. We apply the EGARCH model to estimate the liquidity effect. Our key findings are as follows. First, unlike in other overnight inter-bank markets in foreign countries, we cannot find a liquidity effect on most days of the reserve maintenance period except during the one-to four-day period before settlement day (the end day of the maintenance period). Particularly, there is only a very weak liquidity effect even on settlement day - unlike the case in inter-bank markets in most foreign countries, where it is strong. This may be attributed to the BOK`s liquidity management practice of absorbing excess liquidity or supplementing for liquidity shortages at the market rate on settlement day. In addition, the higher aggregate level of reserve balances in comparison with settlement demand in the banking system is associated with the smaller liquidity effect in the Korean call market. These factors have contributed to the fixedness of the call rate. Second, we find that since the announcement of the increase in reserve requirements in November 2006, the liquidity effect has become stronger than before. This is because the BOK has changed its method of liquidity management to encourage banks to adjust their reserves in more moderate ways. The BOK has minimized liquidity adjustments on settlement day and reduced the number of market interventions during the maintenance period. This has led banks to pay more attention to changes in the aggregate level of reserves than before. In this sense, the BOK`s new framework, which has less frequent but more regular market intervention, is expected to alleviate the fixedness of the call rate. Third, what we refer to as "the banks` call rate," calculated based on the rates quoted by commercial banks only, responds more sensitively to a change in reserves than the overall call rate (the BOK`s operating target and policy rate), which weighs the rates quoted by all participants in the call market. This may be attributed to the fact that call loan volume and interest rate have been dominated by asset management companies, which are under no reserve requirement obligation. This means that the BOK`s operating target might not significantly represent changes in demand and supply in the reserve market. Finally, the banks` call rate responds more sensitively to the impact of a reserve decrease than to that of a reserve increase. This asymmetric response of the banks` call rate to a reserve change reflects the fact that most banks try to avoid the stigma attached to a bank that is short of reserves. This finding indicates that the banks may be reluctant to use the BOK`s newly introduced lending facility.

This study aimed to identify how relative players’height differences in Ssireum matches affect players’performance, skill pattern and skill effectiveness. For this purpose, we selected 103 Kumkang class competitions in which the height difference between two players is 5.0 cm or more. With the selected matches, the frequency of the win, used skills, succeeded skills and failed skills of the short and tall players were analyzed. Results showed that there were statistically significant differences between short and tall players in terms of the frequency of used skills, succeeded skills, and failed skills. Among 5 skill types, short players used skills in the order of waist skill, leg skill, and hand skill, whereas tall players frequently used waist skill and leg skill. Also, Short players had higher success rates of the waist skill and the hand skill, whereas tall players had higher success rates of waist skill and lower success rates of leg skill. Results indicate that the height difference between two players in the Ssireum match can be an important factor influencing skill patterns and skill effectiveness of short and tall players.

The purpose of this study was to investigate the change of performance of driver and iron shot by 12-week weight training for improvement of upper body and core muscle strength in middle aged female golfers. For this purpose, we divided 14 women aged 40-60 years into control group(n=7) and experimental group(n=7) and analyzed swing of driver and iron shots before and after applying weight training. The results showed there were significant improvements in the club speed, ball speed, and distance of the driver and iron shots in exercise group with weight training. On the other hand, control group showed no significant differences in club speed, ball speed, and distance of the driver and iron shots. These results were supported by a two-way ANOVA with a significant main effect of Time(pre vs post) and Time×Group interaction. In conclusion, upper body and core weight training had positive effects on the overall performance of driver and iron shots of middle-aged female golfers and confirmed that they could be useful training for golfers. Also, we suggest that this training might be necessary not only for improving performance of the golf swing but also for prevention of injury.

This study conducted a quantitative and qualitative analysis on five skilled and five unskilled players to improve forehand high-clear skill of amateur badminton players. The analysis was made for swing time, X-Factor (Stretch), trunk rotation angle and wrist joint, elbow joint, shoulder joint, pelvis, trunk angle for the skilled and unskilled. The results are as follows: 1) The time required for each section of the two groups showed a significant difference in P1 (p<.05). 2) The X-Factor (Stretch) angle showed a significant difference in E4 (p<.01). 3) The coordination of the pelvis and trunk segment was more efficient when the skilled person increased the trunk (distal) rotation speed when the pelvis (proximal) rotation speed was the maximum value in the E2-E3 section 5) In shoulder, elbow, and wrist joints, both groups showed proper coordination, but the experts showed higher differences in the rotational speed of the shoulders, elbows, and wrists at E3 (maximum backswing) than the unskilled. In conclusion, the skilled group showed effective high-clear movement through the coordinated movement of the trunk, pelvis, and upper extremity joints in qualitative terms.
