申性休 成均館大學校 1983 論文集 Vol.33 No.-

I made the three male Hurdlers of Korea(our country) in the 110m Hurdle Race as subjects of my research. I could come to the conclusion as follows, from the anlysis of the developed films by taking photographs of First Hurdling with 16mm and 8mm Movie Camera (64 Frame/sec, 70 Frame/sec). 1. The center of gravity moves to the left while they are hurdling, but it turns back to the original point after the go over the hurdle. 2. When hip joint is high, the horizontal distance between hip joint and hurdle is from 21.1 to 26㎝, and that distance is shorter than 30㎝ which was reported by Mr. Kim Won Yong. 3. Although the hurdling time was recorded as from 0.6248sec to 0.6532 sec, that was the later time 0.495-0.593sec which was reported by Terry and Daniel. 4. The horizon shifting distance of the center of gravity in hurdling was 4.15-4.724M, and it was appeared the distance was longer than 4.17M-4.52M reported by Terry and Daniel. 5. The horizon velocity of center of gravity was between 6.3533m/sec and 7.3928m/sec. If the above velocity is conpared with the velocity. 8.3735-7.2491m/sec shown by Terry and Daniel, it was shown that there were great difference between the velocity appeared in my research and that of Terry and Daniel.

The purpose of this study was to examine the kinematical characteristics on the rotational motion in discuss throwing, and to grope for the better discuss throwing technique. The subjects, four collegiate discuss throwing players, were the standing player. 2S-VHS video cameras were used for the data collection. The Direct Linear Transformation(DLT) technique was employed to obtain 3-D position coordinates of 21 landmarks(20 body and 1 disk landmarks(Abdel-Aziz & Kararah, 1971) and a cubic spline function was used for smoothing and differentiation. It also calculates the location of center of mass using Plagenhoef's data. In this study, the rotational motion was divided into 4 events(ROF, RON, LON and REL) and two phases(LT, RT for the data analysis. From those, time duration, displacement of COG, velocity of COG and discuss, and trunk and release angles were calculated, and the following conclusions were drawn: 1. Last phase(LT) showed relatively shorter in time than the other phases. 2. In the displacement of COG, first phase(LT) showed longer displacement in horizontal direction, last phase(RT) showed longer displacement in lateral-medial direction and vertical direction 3. Last(RT) showed faster in the horizontal, lateral-medial and verical velocity. 4. At release, horizontal velocity was superior than lateral-medial and vertical direction. 5. The players rotated their body with backward. 6. The angular velocity of body was larger in beginning of rotation.

본 연구는 조사료 연중생산이 불리한 남부산간지역(전북 장수군)에서 봄과 여름에 재배하는 조사료 귀리의 적정 파종과 수확시기를 구명하고자 하였다. 시험품종은 여름 재배용 국산 조사료 귀리 품종 '하이스피드'와 '다크호스'이었다. 남부산간지에서 봄과 여름 조사료 귀리의 적정 파종기와 수확시기를 구명하기 위하여 파종과 수확시기를 달리하여 각각 재배하고 조사료 수량과 품질 변화 양상을 분석하였다. 시험장소는 전북 장수군 소재 농가 논 포장이었다. 2015년과 2016년에 2년간 수행한 연구결과를 요약하면 다음과 같다. 1. 조사료 귀리를 2월 하순, 3월 상순과 중순에 파종하였을 때, 출수까지 적산온도가 각각 690℃, 724℃, 743℃이었고, 8월 상순, 중순, 하순에 파종하였을 때, 출수까지 적산온도는 각각 1,449℃, 1,091℃, 888℃이었다. 2. 조사료 귀리 품종(하이스피드, 다크호스)을 2월 하순부터 9일 간격으로 3월 중순까지 파종하면 출수기는 모두 5월 10일~5월 16일이었고 평균 3일 정도만 늦었고, 8월 상순부터 10일 간격으로 8월 하순까지 파종하면 출수기는 모두 10월 13일~10월 15일이었고 평균 1~2일 정도만 늦어지는 것으로 나타났다. 특히 9월 상순에 파종한 조사료 귀리는 출수하지 않았다. 3. 봄과 여름 조사료 귀리의 건물수량과 품질은 모두 파종 시기에 유의미한 영향을 받지 않았다. 4. 봄 조사료 귀리의 조단백 함량은 5월 하순에 수확한 것이 12.0%로 가장 높았고 그 이후 수확시기가 10일씩 늦을수록 급격히 감소하여 6월 상순에는 8.2%, 6월 중순에는 단백질 함량이 6.5%까지 감소하였고, TDN 함량(59~62%)도 비슷한 경향이었지만 감소폭은 작았다. 5. 여름 조사료 귀리는 파종시기가 늦을수록 단백질과 TDN 함량이 증가하는 경향이었고, 10월 하순부터 11월 중순까지 10일 간격으로 수확한 조사료 귀리의 조단백 함량이 8.4~8.7%, TDN 함량이 59.0~60.1% 정도이었다. 6. 봄 조사료 귀리는 6월 상순과 6월 중순에 수확한 건물수량이 각각 18.7톤/ha와 19.5톤/ha으로 5월 하순에 수확한 것보다 각각 83%와 91% 정도 높았다. 7. 여름 조사료 귀리는 11월 상순과 중순에 수확한 건물수량이 각각 12.5톤/ha와 12.1톤/ha으로 10월 하순에 수확한 것보다 각각 75%와 71% 정도 높았다. 8. 봄과 여름 귀리의 조사료 수량은 출수 이후 수확까지 적산온도와 높은 정의 상관관계를 나타내었다. 9. 봄과 여름 조사료 귀리의 건물수량과 품질을 고려하였을 때, 남부산간지에서 조사료 귀리를 봄에 재배할 경우에 3월 15일까지 파종하고 6월 10일경에 수확하고, 여름에 재배할 경우에는 8월 25일경까지 파종하고 11월 상순 이후 수확하면 단백질 함량이 8% 이상인 고품질 조사료의 최대 수량을 얻을 수 있는 것으로 판단되었다. Oats (Avena sativa L.) represent a good forage crop for cultivation in regions with short growing periods and/or cool weather, such as the mountainous areas of southern Korea. In this study, using the Korean elite summer oat varieties 'High speed' and 'Dark horse', we aimed to determine the optimal time to plant and harvest forage oats seeded in spring and summer in a mountainous area. Seeds were planted three times from late February and early August at 9- or 10-days intervals, respectively, and plants were harvested three times from late May to October at 10-day intervals. The experiment was carried out in an upland field (Jangsu-gun Jeonbuk) in 2015 and 2016. We investigated the changes in forage yield (FY) and quality [crude protein (CP) and total digestible nutrient (TDN) contents] based on the time of planting and harvest. Neither the forage quality nor yield of either spring and summer oats was significantly influenced by the time of planting. The CP of spring oats harvested three times at 10-day intervals from late May was 12.0%, 8.2%, and 6.5%, thereby indicating a reduction with a delay in the time of harvest. In summer oats, CP ranged from 8.4% to 8.7%, although unlike CP in spring oats, was not significantly influenced by the time of harvest. For both forage types, harvest time had no significant effect on TDN. The FY of spring oats harvested in late May and early and mid-June was 10.2, 18.7, and 19.5 ton ha^-1, respectively, with that of oats harvested on the latter two dates being significantly increased by 83% and 91%, respectively, compared with that in late May. Similarly, the FY of spring oats harvested in late October and early and mid-November was 7.1, 12.5, and 12.1 ton ha^-1, respectively, with that of oats harvested on the latter two dates being significantly increased by 75% and 71%, respectively, compared with that in late October. Taking into consideration forage yield and quality (not less than 8% CP), it would be profitable to plant spring oats in the mountainous areas of southern Korea until March 15 and harvest around June 10, whereas summer oats could be beneficially planted until August 25 and harvested from early November.

The purpose of this research is to offer the basic data for Korean Javelin throwers, through analyzing at the men Javelin qualifying in Seoul Olympics. The kinematic data were obtained of the subjects(n = 21) who were throwed more than 75m through Javelin qualifying. The analysis of each phase used the data Analyzer(MFG by L-W PHOTONC) from the data obtained through high speed cinematographic method(64fps and shutter speed is 1/400 sec) The results are as follows : 1. Delivery phase 1) The width of stance is 116.44∼1.56.94cm and each individual ratio between stance and hight is about 61∼86.7% it shows that the width of stance must have 70% of each individual hight for not decreasing horizontal velocity. 2) The body center of gravity moving horizontal velocity is 4.31∼6.34m/sec and the average is 5.43m/sec. 3) The pull distance of right foot is 25.19∼64.13cm and its average is 46.40cm The pull distance of right foot is increase because the stance to too wide adequate stance is an essential key to prevent the exceed amount of pull distance of right foot. 4) The angle of lean body is 58.5˚∼70.5˚ and its average is 65.26˚ when the upper body has the most extension the most reasonable the angle of lean body is 80˚∼90˚ because the less the angle of lean body, the less the horizontal velocity. 2. Throwing phase 1) The body center of gravity moving horizontal velocity is 2.58∼3.68m/sec and the average 319m / sec. 2) At the releasing moment the angle of gravity is 69˚∼84˚ and the average angle is 75.6° the angle of gravity most exceed 90˚ to throw the Javelin more further.

신성휴,Jin-Seok Lee,Beom-Young Son,Jung-Tae Kim,Sang Gon Kim,Mi-Jung Kim,Sun-Lim Kim,Young-Up Kwon,Seong-Bum Baek,우미옥,Hwan Hee Bae 한국작물학회 2014 Journal of crop science and biotechnology Vol.17 No.4

Sweet corn has a short growing period of 80 to 90 days in Korea, which allows famers to grow this crop using various croppingsystems. This objective of this study was to find the optimum plant density for Korean sweet corn (se) hybrids ‘Godangok’ and‘Guseulok’ when they were grown as the second crop. Plant densities were 5,710, 6,670, and 8,000 plants 10a-1 and planting dateswere 20 July and 30 July, 2013. There was no interactive effect between plant density and hybrid for all the analyzed parameters inthis study. Increasing plant density up to 8,000 plants 10a-1 led to no significant gain in marketable ear yield. Although the total numberof ears was increased about 21 ~ 33% at the highest plant density than at lower densities, e.g., 6,670 or 5,710 plants 10a-1, the percentageof marketable ear number and individual ear weight decreased with increasing plant density. Individual ear weight of marketableears was significantly greater, e.g., by 8 ~ 13%, at 5,710 plants 10a-1 and 6,670 plants 10a-1 than at 8,000 plants 10a-1. Similarresults were obtained for ear length and width and filled length under the given plant densities, which indicated that increasing plantdensity may decrease individual ear fresh weight and ear size with good tip fill. Increasing plant density up to 8,000 plants 10a-1caused the lowest harvest index, which resulted in little gain in fresh ear yield compared to the lower plant densities of 5,710 and6,670 plants 10a-1. These results indicated that the optimum plant density for those sweet corn hybrids planted in July would bebetween 5,700 and 6,700 plants 10a-1 in terms of marketable ear yield and quality of marketable ears
