        한국판 운동의존성 척도의 타당화 검증

        오영택,양명환 국기원 2019 국기원태권도연구 Vol.10 No.3

        The purpose of this study was to verify whether the Exercise Dependence Scale-Korean Version(EDS-K) can be applied to Korean Taekwondo athletes properly and reliably. Two separate studies were conducted to achieve this goal. In study 1, 231 Taekwondo athletes were included, in study 2, 355 athletes were participated. Construct validity was verified through exploratory and confirmatory factor analysis, and criterion-related validity was verified through correlation analysis with the criterion variables, and were examine internal consistency reliability analysis. The main results were as follows. First, in study 1, seven factors were extracted from 21 items through exploratory factor analysis. The 21 item 7 factor scale obtained a good reliability value and confirmed the 7 factor structure through confirmatory factor analysis. Convergent validity and discriminant validity were also found to be good. Second, criterion-related validity was obtained through the correlation analysis between passion, deliberated practice and the seven factors of EDS-K developed in this study. Second, as a result of study 2, the factor structure shown in study 1 was reproduced and adequate validity(convergent and discriminant) and internal consistency were reverified. We also reaffirmed the criterion-related validity through correlation analyses between passion, perfectionism, deliberated practice, shame and EDS-K. Third, the construct validity was analyzed by the experimental method, and there were significant differences according to gender and school level. In conclusion, EDS-K is a multidimensional tool that can reliably and properly measure the exercise dependence of Korean Taekwondo athletes. 본 연구의 목적은 한국판 운동의존성 척도(EDS-K)가 우리나라 태권도선수들에게도 타당하고 신뢰롭게 적용될 수 있는지 여부를 검증하였다. 연구 1에서는 태권도 선수 231명을 대상으로, 연구 2에서는 태권도 선수 355명을 대상으로 이루어졌다. 탐색적, 확인적 요인분석을 통해 구인타당도를 검증하고 준거변인들과의 상관관계 분석을 통하여 준거타당도 검증과 신뢰도분석을 실시하여 다음과 같은 주요 결과를 추출하였다. 첫째, 탐색적 요인분석을 통하여 21문항 7개의 요인을 추출하였다. 21문항 7요인 척도는 양호한 신뢰도 값을 얻었으며, 확인적 요인분석을 통해 7요인 구조를 확증하였다. 또한 본 척도의 수렴타당성과 판별타당성도 양호한 것으로 나타났다. 열정, 의도적 연습 변인들과 본 연구에서 개발된 7요인들 간의 상관관계분석을 통하여 적절한 준거타당도를 확보하였다. 둘째, 연구 2의 분석결과 연구 1의 요인구조를 재확인하였고, 적절한 수준의 타당도와 신뢰도를 확보하였다. 또한 열정, 완벽주의, 의도적 연습, 수치심과 EDS-R간의 상관분석을 통하여 구인타당도를 재확인하였다. 셋째, 구인타당도 분석 결과, 성별과 학교급간에 따라서 유의한 차이를 보였다. 결론적으로 EDS-K는 한국 태권도선수들의 운동의존성을 신뢰롭고 타당하게 측정할 수 있는 다차원의 도구임을 확인하였다.

        직접분사식 디젤기관에서 EGBE 첨가에 의한 배기가스 배출특성과 분석에 관한 실험적 연구

        오영택,최승훈,O,,Yeong-Taek,Choe,,Seung-Hun 대한기계학회 2002 大韓機械學會論文集B Vol.26 No.3

        Improvements of fuel properties have become essential for exhaust emission reduction as well as for optimization of directly-related design factors and exhaust gas aftertreatment. In this study, the potential possibility of oxygenated fuel such as ethylene glycol mono-n-butyl ether(EGBE) was investigated for the sake of smoke reduction from diesel engine. Because EGBE include oxygen content approximately 27%, it is a kind of effective oxygenated fuel that the smoke emission of EGBE is reduced remarkably in comparison with commercial diesel fuel, that is, it can supply oxygen component sufficient at high load and speed in diesel engine. And, it was tried to analyze the quantities of the low and high boiling point hydrocarbon among the exhaust emissions in diesel engine. It have been investigated by the quantitative analysis of the hydrocarbon $C_1$~ $C_{6}$ using the gas chromatography. This study was carried out by comparing the chromatogram with diesel fuel and diesel fuel blended EGBE 20vo1-%. The results of this study show that the hydrocarbon $C_1$~C$_{6}$ among the exhaust emission of the mixed fuels are exhausted lower than those of the diesel fuel at the all load and speed. In particular, high boiling point hydrocarbons such as $C_{5}$ and $C_{6}$ were reduced remarkably at high speed and load.d.

      • 디젤기관의 성능진단을 위한 프로그램 개발

        吳永澤 全北大學校 1991 論文集 Vol.33 No.-

        The purpose of this study is to develop programs for engine performance test in a naturally aspirated D.I. diesel engine. To accomplish this object, first of all, we must develop the new domestic technology and produce products which make use of the derived technology. In the experiment, while the engine was operated for a range of speeds, loads, injection timings and a kind of fuels, the rate of heat release and its quantitive analysis by Wiebe's function from indicator were calculated. These programs have the ultimate goal that is to found basic technology data for activated domestic automobile industry and extended a chance to the college men and specialist with the fundamental experimentation. The obtained results are as follows: 1. It was developed a fundamental data to calculate the rate of heat release and the rate of combustion, that is, combustion analysis for localization of engine analyzer with personal computer in diesel engine, and we could decide the ignition, misfire and ignition easily from the rate of heat release. 2. The rate of heat release by quantitive analysis was represented by six parameters. Engine performance can express by those parameters which consist of the rate of heat release. We were able to know that premixed combustion period(θ^p ≒ 7.0 ℃A), diffusion combustion characteristics (M^p ≒ 3.0) and premixed combustion characteristics values(M^d ≒ 0.5) were uniform in spite of any engine operation conditions.

        Samter's Triad 환자에서 Tramadol 주사 후 발생한 급성 천식 발작 1예

        오영택,조경래,최정환,허건 대한이비인후과학회 2010 대한이비인후과학회지 두경부외과학 Vol.53 No.2

        Samter's triad is a well known syndrome and is characterized by a triad of asthma, aspirin or NSAID sensitivity and chronic sinusitis with nasal polyp. Chronic sinusitis with Samter's triad is difficult to treat completely and has poor prognosis. Tramadol is a non-opioid analgesic that rarely shows respiratory suppression and is known to be relatively safe because it does not inhibit prostaglandin synthesis. For that reason, patients with asthma may avoid drug-induced exacerbations of the disease by substituting Tramadol for NSAIDs. We experienced a case of asthma attack in a patient with Samter's triad after Tramadol injection. Korean J Otorhinolaryngol-Head Neck Surg 2010;53:121-5
