염동철(Yeom Dong-Chul) 한국체육과학회 2011 한국체육과학회지 Vol.20 No.4

The purpose of this study was to examine the effects of modified gradual overload training on performance (squat, snatch) and biochemistry factors(blood lactate, stress related hormones) in elite weight lifters. All subjects (n=16, Age: 24.1±4.3yr; height: 176.5±3.3㎝; Weight: 81.8±19.31㎏; Career: 9.9±2.3yr) were participated normal (GT) or modified gradual overload training(M-GT) during six weeks (6 time week-1, 2~hour/day). The 1RM of squat and snatch was markedly increased when applied M-GT training compared to that of GT. blood lactate level after squat 1RM test was significantly higher immediately after 1RM test and all recovery time course in M-GT. blood lactate level in M-GT after snatch 1RM test was same as squat 1RM test except for immediately after and 3, 5min recovery time compared to GT. Blood IGF-1 level has no significantly difference between GT and M-GT. Interestingly, Serum norepinephrine and cortisol level were significantly decreased when applied M-GT. these results showed that M-GT may improve weight lifting performance which is not because of growth related hormone but stress related hormone.

염동철 ( Yeom Dong-chul ),원진희 ( Won Jin-hee ) 한국체육대학교 체육과학연구소 2020 스포츠사이언스 Vol.38 No.1

본 연구는 시계열 분석을 활용한 역도선수들의 경기력을 예측하기 위한 목적으로 진행되었다. 이러한 목적에 따라 국내 전국체전에 참가한 역도 선수들 중 남자(77kg), 여자(58kg) 선수들의 10년 동안의 경기 기록을 준거로 시계열 분석을 통해 경기력 예측모형을 산출하였다. 10년 간의 기록을 토대로 시계열 자료를 생성한 다음 각각 선수집단들의 순차도표를 평가한 결과 남자 및 여자선수 모두 계절성이나 차분은 나타나지 않았다. 그리고 시계열 모형의 생성을 통해 각각 자료의 독립성을 검토한 결과 생성된 모형은 적합기준을 준수하는 것으로 나타났으며 남자선수의 경우에는 추세 및 차분은 나타나지 않았으나 여자선수의 경우에는 차분은 나타나지 않았으나 추세가 있는 것으로 나타났다. 이에 따라 남자(77kg)선수의 경우에는 지수평활모형의 단순추세분석을 적용하였으며 여자(58kg)선수의 경우에는 지수평활모형의 Holt 선형추세분석을 적용하였다. 이러한 과정을 통해 선수들의 예측모형을 도출한 결과 남자(77kg)급에서는 기록의 향상 없는 인상과 용상 총합 301.32kg~303.84kg의 범위로 예측되었다. 그러나 여자(58kg)급 에서는 165.41kg~183.9kg의 범위 안에서 지속적으로 향상되는 것으로 나타났다. The purpose of this study was to predict the performance of weightlifters using time series analysis. According to this purpose, the performance prediction model was calculated through time series analysis based on the 10-year competition records of men (77kg) and women (58kg) among weightlifters who participated in the national sports competition in Korea. After generating time series data based on a 10-year record, each of the sequential charts of the athletes' groups showed no seasonality or differential. In addition, after examining the independence of the data through the creation of a time series model, it was found that the models produced conformed to the criteria for compliance, and that there was no trend and differential for male athletes, but there was no difference for female athletes, but there was a trend. Therefore, simple trend analysis of index smoothing model was applied for men (77kg) and Holt linear trend analysis for women (58kg) models was applied for women. As a result of deriving the athletes' prediction models through this process, the men's (77 kg) class was expected to have a range of 301.32 kg to 303.84 kg overall for the clean and jerk and the increase in record-breaking performance. However, in the women's (58 kg) class, continuous improvement was shown in the range of 165.41 kg to 183.9 kg.

염동철 ( Yeom Dong-chul ),조준용 ( Cho Joon-yong ),이정호 ( Lee Jung-ho ) 한국체육대학교 체육과학연구소 2016 스포츠사이언스 Vol.34 No.1

본 연구는 엘리트 육상 단거리 선수 9명을 대상으로 단 기간의 크레아틴 섭취 후 급성 카페인 섭취가 운동수행능력에 미치는 영향을 분석하고자 하였다. 이를 위해 선수들은 시기별로 CON 집단, CRE+CAF 집단, CRE+PLA 집단으로 구분하여 실험에 참가하였으며, 이전 처치에 따른 효과를 최대한 배제하기 위해 1주일 간의 wash-out 기간을 두었다. 5일간의 크레아틴 섭취 후 6일차에 카페인(혹은 위약)을 섭취하고 2시간 30분 후에 등속성 각근력 검사, 무산소성 파워검사를 실시하였다. 신체구성성분을 분석한 결과, 체중, BMI, 체지방량, BMC, 체지방률은 집단간에 통계적으로 유의한 차이는 없었다. 제지방량은 통계적으로 유의한 차이가 있었으며, CON집단에 비해 CRE+CAF, CRE+PLA 집단에서 모두 증가한 것으로 나타났다. 둘째, 등속성 각근력을 분석한 결과, 슬관절은 왼쪽 신근력의 평균파워는 통계적으로 유의한 차이가 있었지만, 다른 항목에서는 차이가 없었다. 오른쪽 신근력의 경우에는 모든 항목에서 통계적으로 유의한 차이가 없었다. 굴근력의 오른쪽은 최대파워에서 CRE+CAF 집단에 비해 CRE+PLA 집단에서 통계적으로 유의하게 감소한 것으로 나타났다. 왼쪽의 경우, 모든 항목에서 통계적으로 유의한 차이는 없었다. 요부관절 등속성 각근력의 결과, 신근력과 굴근력의 모든 항목에서 통계적으로 유의한 차이는 나타나지 않았다. 셋째, 무산소성 파워를 검사한 결과, 모든 항목에서 통계적으로 유의한 차이는 없었다. 이상의 결과를 종합해 볼 때, 단 기간 크레아틴 섭취 후 급성 카페인 섭취는 운동수행능력에 영향을 미치지 않은 것으로 나타났다. 하지만 크레아틴 섭취 후 급성 카페인 섭취 시 운동수행능력이 증가하는 경향은 나타났다. 따라서 사례수를 보강하고 객관적인 측정을 추가적으로 실시한다면 의미 있는 결과를 얻을 수 있을 것으로 생각된다. This study aims to analyze the impact of the rapid caffeine intake after short-term creatine intake on athletic performance with nine elite sprinters. For this purpose, athletes divided into a CON group, CRE+CAF group and CRE+PLA group by the period participated in experiments, and in order to exclude the effect of the previous treatment to the maximum, this study put a 1-week wash-out period. 2 hours and 30 minutes after they took in caffeine (or placebo) on Day 6 after creatine intake for 5 days, an isokinetic leg strength test and an anaerobic power test were conducted. As a result of an analysis of body composition, there were no statistically significant differences in weight, BMI, fat mass, BMC and body fat ratio among the groups. There was a statistically significant difference in fat mass, and it turned out that it increased in both CRE+CAF group and CRE+PLA group as compared to the CON group. Second, as a result of analysis of the isokinetic leg strength, there was a statistically significant difference in the average power of the left extensor in the knee joint, but there was no difference in the other items. There were no statistically significant differences in all items in the right extensor. On the right side of the flexor, there was a statistically significant decrease in the maximum power in the CRE+PLA group as compared to the CRE+CAF group. On the left side, there were no statistically significant differences in all items. As a result of measurement of the isokinetic leg strength of the lumbar joint, there were no statistically significant differences in all items of the extensor and flexor. Third, as a result of a test of anaerobic power, there was a tendency of increases in all items in the CRE+PLA group as compared to the CON group, and there was a tendency of decreases in all items in the CRE+PLA group as compared to the CRE+CAF group, but there were no statistically significant differences. To sum up the above findings, it turned out that rapid caffeine intake after short-term creatine intake did not affect athletic performance. However, there was a tendency of increase in athletic performance in the rapid caffeine intake after the creatine intake. Therefore, increasing the number of cases and additionally making objective measurements could obtain a meaningful result.

Tunable gratings in a hollow-core photonic bandgap fiber based on acousto-optic interaction

Yeom, Dong-Il,Park, Hyun Chul,Hwang, In Kag,Kim, Byoung Yoon The Optical Society 2009 Optics express Vol.17 No.12

<P>We demonstrate a coherent intermodal coupling in a hollow-core photonic bandgap fibers (PBGF) using an acoustic grating. A theoretical study on the properties of acoustic and optical wave propagating the PBGF is performed indicating that the applied frequency higher than 10 MHz is required to obtain the acousto-optic interaction at the wavelength around 1550 nm. Wavelength-tunable coupling from fundamental mode to higher-order core modes is achieved with more than 90% coupling efficiency at the applied frequency of 11.54 MHz. The low dispersive properties and the mode filed distributions of the higher-order guided modes of the air-core PBGF in the experiment show reasonable agreement with the simulation results.</P>

The corrugated steel-plate is ductile structural member which has high sectional properties compared with same thickness of plate. Corrugated steel-plate resist the external force by the combined action of retained soils and structures. Since it is easy to transport and assemblage of in-situ, the duration and cost of construction can be reduced. Corrugated plate structures, therefore, are widely used in culverts, hydro passages and simple bridges. In this study, behavior analysis is performed to corrugated steel-plate in earth with elastic-plastic soil element method and spring soil element method. An object of this study is to decide more suitable method which indicate practical behavior of corrugated steel-plate in earth.
