        정구 한국스포츠학회 2019 한국스포츠학회지 Vol.17 No.1

        본 연구는 정구선수의 소속별 스포츠 상해관련 요인 분석을 하여 최종적으로 정구 지도자와 선수들의 스포츠 상 해에 대한 재활과 향후 대처 방안에 대한 구체적인 정보를 제공하는데 연구의 목적을 두고 실시하였다. 이에 본 연구는 소속별 정구 선수 179명에게 스포츠 상해 특성을 분석하기 위한 설문을 실시하였으며, 설문조사 결론은 다음과 같다. 상해 유형에 관한 분석결과 근육통과 인대손상의 빈도가 높게 나타났으며, 소속별 상해원인 분석결과 환경적인 요소에 서는 소속별 모두 장소에서 상해유발 요인으로는 훈련강도와 훈련방법에서 통계적으로 유의한 빈도에 의한 차이를 보 였다. 재활치료에 관한 분석결과 중 재활치료 장소로 병원과 한의원에서 주 1-2회의 치료횟수에 대한 유의한 빈도 차이 를 보였으며, 상해 후 경기 복귀 기간에 대한 결과는 고등부와 대학부는 1주미만, 일반부는 2-3주에 통계적으로도 유의 한 빈도에 의한 차이를 보였다. 소속별 상해 인식대한 분석결과에서는 고등부는 ‘아니다’ 와 대학부와 일반부에서 ‘그렇 다’ 재 상해에 대한 분석결과에서는 고등부는 ‘없다’ 대학부와 일반부는 ‘있다’에 통계적으로 유의한 빈도에 의한 차이를 보이는 결과를 보였다. 결론적으로 정구 선수들의 스포츠 상해 방지를 위한 기술의 특성을 과학적으로 분석 및 체계적이 며 효과적인 운동 프로그램을 개발 하는데 노력을 하여야 하며, 지도자들 또한 선수들의 상해 예방을 위한 교육 및 훈련 지도가 필요함을 제시하고 있다. The purpose of this study is to analyze sports injury-related factors at each teams in soft tennis players and provide information on rehabilitation and further coping methods for sports injuries for soft tennis coaches and players. A questionnaire survey was conducted with 179 soft tennis players at each teams to analyze the characteristics of sports injuries. The following conclusions were drawn. The result of analyzing injury types showed high frequency in muscle pain and ligament injury. As a result of analyzing injury causes at each teams, first, environmental elements were statistically significantly different in all places at each teams and second, injury causing factors were statistically significantly different in training intensity and training methods. For the results of analyzing rehabilitation, there was a significant difference in frequency in hospital and Oriental medicine clinic for rehabilitation place and once or twice per week for rehabilitation frequency. For the periods for return to play after injury, a statistically significant difference in frequency was found in less than one week for high school and university teams and in 2-3 weeks for general teams. For injury perception at each teams, there was a statistically significant difference in frequency in 'No' for high school teams and 'Yes' in university and general teams. For re-injury at each teams, while there was a statistically significant difference in frequency in 'No' for high school teams and in 'Yes' for university and general teams. In conclusion, efforts should be made to scientifically analyze the characteristics of techniques to prevent sports injuries and develop systematic and effective sports programs for soft tennis players. Moreover, coaches should receive education and training coaching to prevent players’sports injuries.

        성상신경절차단으로 유발된 혈역학적 변화 및 임상증상

        이정구,박원균,전재규,한성욱,김중강 대한마취과학회 2000 Korean Journal of Anesthesiology Vol.38 No.6

        Background : Stellate ganglion block (SGB) is the most common nerve block procedure in pain clinics. To evaluate chnnges in the hemodyoamics and peripheral blood flow on the affected extremity after SGB, SGB was performed unilaterally one at a time on the right and left stellate ganglions by injecting 1% mepivacaine 10 ml withoet epinephrine in a designated healthy man. Methods : SGB was repeated 16 times in and subject (right side SGB: 8, left side SGB: 8) by the same clinician. The tnean artetial pramare (MAP), heatt rate (HR), cardiac index (CI, systemic vascular resistance index (SVRl) and peripheral blood flow were measured in the supine positian before (control), and 3, 6, 9, 12, and 15 minutes after SGB using thoracic electrical bioimpedence (Bioz system A-10043, Cardiodynatnics, USA), sphygomanometer, and flow meter, Results : The values after SGB including MAP, HR, CI, and SVRI increased slightly compared to the control value, However, peripheral blood flow incraeed significantly (p $lt; 0.05). The SGB did not affect systematic hemodynsmics and the comparison between left and right SGB in hemodynamic changes were not clinically significant. Following SGB, ptosis (100%), nasal stiffness (100%), skin temperature elevation (100%), hoarseness (100%), numbness (81%), dizziness (25%), and swallowing difficulty (25%) were observed. Conclusions : We concluded that SGB showed to be a hemodynamically safe clinical technique. (Korean J Anesthesiol 2000; 38: 1l9~1016)

        표본검정성적으로부터 검정간격의 생산량을 추정하기 위한 계수 산출

        이정구,주종철 한국축산학회 1991 한국축산학회지 Vol.33 No.5

        This research was performed to estimate the shape of an average lactation curve and to develop adjustment factors to reduce errors in estimating test-interval milk yields from sample-day production. Complete records were available for 187 lactations for the period from calving to 310 days in milk. The average daily production increased rapidly from calving to a peak at 39 days in milk and declined at a nearly linear rate. To estimate test-interval yields accurately adjustment for the location of sample days on the lactation curve, especially the interval from talking to first sample days, interval around the lactation peak and interval after last sample day were required. Separate factors were developed for the three interval,; of the lactation curve that require the adjustment. Factors from this study were similar to USDA factors but different from those adopted in Korea Animal Improvement Association.

        사료 제한급여 수준에 따른 정상 및 왜소 육용종계의 생산능력 비교;1. 사료급여 수준이 육성계의 성장능력에 미치는 효과

        이정구,주종철,장재익 한국축산학회 1991 한국축산학회지 Vol.33 No.11

        This experiment was performed to compare the growth performance of normal and dwarf broiler breeders under various degrees of feed restriction and to evaluate the breeder's recommended growth curve and corresponding feeding program for each strain. The feeding programs within each strain were designed according to the desired growth curves as ad libitum(AL). 5% above the breeder's standard curve (+5%), standard curve(STD), and 5% below the standard curve(-5%). The normal strains consumed 26 to 33% more feed than the dwarf strain under the AL feeding programs and 3 to 9% more under the STD. Under the STD feeding, the normal strains consumed 3% more feed than the feed allowance recommended by the breeder's guide, and the dwarf strain consumed 10% more feed. At 21 weeks of age the dwarf pullets weighed about 86% of the normal strains under the STD feeding programs. Viability was significantly lower for the dwarf strain than for the normal strains but was not different between feeding programs within a strain. The degree of feed restriction had a significant effect on delay of sexual maturity of pullets.

        검정간격의 유량을 보정하기 위한 한국종축개량협회 계수와 미국농무부 계수의 정확도 비교

        이정구 한국축산학회 1993 한국축산학회지 Vol.35 No.2

        The purpose of this research was to compare accuracy of Korea Animal Improvement Association (KAIA) factors with USDA factors for adjusting test-interval milk (TIM) yields. Data used in this analysis were 721 lactation records with 305 daily milk yields. When test-interval yields adjusted by KAIA factors and by USDA factors were compared with actual yields, by stage of lactation, USDA factors could reduce bias of TIM yields from actual yields more effetively than KAIA factors all in the first. second, and last test intervals. When test days of individual record were randomly chosen at 26 to 34 day intervals, bias of TIM yields from actual yield was largest in the first test interval(78.5㎏ for first lactation and 94.0㎏ for later lactations), the second test interval( -20.0㎏ and -22.6㎏), and the interval after last test-day(10.9㎏ and 15.0㎏). The bias wasn't reduced reasonably in the TIM yields adjusted by KAIA factors in any test interval whereas the amount of bias in the yields adjusted by USDA factors was reduced effectively in all of the three test intervals. Sampling errors of test interval yields adjusted by USDA factors were equal to or smaller than ones adjusted by KAIA factors.

        암성 통증 치료를 위한 경막외 카테터 터널 거치법

        이정구,전재규,정정길 대한통증학회 1991 The Korean Journal of Pain Vol.4 No.2

        Continuous epidural analgesia with intermittent morphine injection is a good technique for the management of intractabie cancer pain. Since epidural tunnelling was introduced for the first time to our institution in 1988, it has been widely used for the cancer pain management. Recently epidural tunnelling was introduced for the keeping an inserted catheter for a long period of time. Twenty-five patients with terminal cancer had been used an epidural tunnelling at the pain clinic of Dongsan Medical Center during the period of 3 months in 1991. Among the 25 patients, l4 were male and 11 were female, and most of them were at the ages of 6th decade. The causes of pain were from stomach cancer in l2, CBD cancer in 3, hepatoma in 2, pancreatic cancer in 2, uterine cervical cancer in 2, and miscellaneous cancer in 4 cases respectively. The outcome of treatment were excellent results in 14(56%), good in 9(36% ), and moderate in 2.patients(8%). Accordingly satisfactory pain relief was achieved in 92% of the patients. It is suggested that this long-term management of intractable cancer pain by epidural bupivacaine and morphine with epidural tunnelling is satisfactory and reliable.
