The purpose of this study was to analyse motion of the one-turn in alpine snowboard. A total of 4 elite Alpine snowboard players were recruited to participate. The experiment was performed slope for experts while the kinematic three dimensional data was recorded and analyzed. Results show that: The height of the center of the mass at the fall line is 83.67±5.41 ㎝, the change of the center of the mass is 0.54±0.48 ㎝, the maximum speed in the center of mass is 25.14±3.82 ㎧, the angle of line of the COM at the fall line is 38.7±4.19 degree, the ROM of trunk angle is 15.72±4.66 degree, the ROM of upper-left thigh angle is 8.49±3.84 degree, the ROM of steering angle is 3.73±2.48 degree, the distance from flag is 1.24±O.55 m.

We projected of analysis that was aimed at enhanced kick performance of football posture for adolescent athletes and was measured lower limb angle, displacement of plantar center of pressure(COP) were occurred during each inside kick and instep kick(long kick). Healthy adolescent athletes(n=10, male, age: 13.6±.52) were recruited for our project. Range of motion(ROM) over Hip, Knee and Ankle Joint were measured by three-dimensional analysis using inertial measurement units. COP of each kicking and support foot was measured from sensor insole. Statistical analysis of independent t-test was performed(p<.05). The results revealed that inside kick caused greater ROM than instep kick over the phase for preparing kick in almost all joints. Inside kick showed smaller ROM than instep kick over the phase for kicking. COP displacement of support foot from inside kick was smaller than instep kick with significant(p<.05) when the event of initial contact of support foot or toe-off of kicking foot from the ground arose. These results suggest inside kick and instep kick have the different tendency of ROM over joint angle of lower limbs each other and have the different tendency of behavior strategy for stability of center of body in football athletes when the foot for support of kicking contacted on the ground.

스탈린주의의 근대성과 ‘밤의 마녀들’

소비에트 권력은 나치독일과의 총력전을 경험하면서 여성들을 최전선의 적진폭격을 위한 야간비행에 내세우기까지 하였다. 그러나 이것은 권력에 의한 강제라기보다는, 1930년대 소비에트 여성들에게 주입된 근대성, 예를 들어 양성평등, 여성의 공적영역 진출, 건설ㆍ개척과 자연정복, 꿈과 미래의 영역인 창공, 과학기술의 총아인 비행기 조종과 낙하산 점프, 유사시 사회주의 조국수호의 성스러운 임무 강조 등의 결과로 인한 여성들의 ‘자발적’ 참여라는 측면이 매우 강하다. 본질적으로는 여성동원이면서도 상당수 여성의 적극적인 ‘동의’가 표출되었다는 점에서, 대중독재의 한 유형인 스탈린체제의 성격이 극명하게 드러나는 대목이기도 하다. 아울러 여성의 적극적 참여와 동의라는 형태로 대중적 동원과 조직화에 일정하게 성공했다는 점에서 권력에 내장된 근대성이 두드러지게 나타나는 경우이기도 하다. 필자는 당시 몇몇 여성 비행사나 항법사의 기록에서 제시되고 재생산되는 당시 소비에트 사회의 지배담론에 유의하면서, 이를 여성 전투원이 내면화하고 전유한 모습을 밝히면서 스탈린체제의 근대화 프로젝트가 전시 여성의 의식과 행동 속에 여전히 영향을 주고 있음을 제시하고자 한다. Over the course of the Great Patriotic War, 1941-1945, Soviet women volunteered to the front. Among them were ‘the Night-Witches’, some decades of women who also mastered night bombers, in particular. Women’s compatibility with combat, in defense of their country was a product of the radical changes that Stalinist society underwent in the 1930s.

We consider the biomechanical analysis of four professional male snowboarders in order to produce basic data, which allows for improving the snowboarding performances of both athlete and amateur snowboarders. We measured the low limb angle and main muscle activation on snowboarding while the male snowboarder was in a snowboard riding and accoutered with whole body harness or upper body harness in simulator. The results show that the use of the whole body harness is more effective in restricting on hip joint and in activatiing left lateral gastrocnemius when the male snowboarder maintained snowboarding posture on the simulator. Our study suggests that application of whole body harness will be more suitable to posture training on the simulator than using upper body harness.

This study which it sees 2 people national athlete players of horizontal bar items technical analysis it leads in the object and also the trouble raises the completion degree of technical Yamawaki operation, becomes the help in light vigorous improvement and character it accomplishes, the result with afterwords is same. S1 it will see the angle of the important joint which puts out the aerial operating time which is longer S2 than indolently and the location in the body center when rotating the body from aerial operation, with the big thing appeared with the fact that it catches the seal with rotation the above the half wheel, shoulder joint angle also it appeared. Change in the body center S1 appeared with the fact that the center from the seal falls plentifully from the front and rear axis, from aerial operation the body moved in the landing at the time of and with the fact that the right and left celebration central movement is big it appeared. S2 operations compared in S1 and operation it is stable but a slowly high jump with the fact that the body center appeared with the low-end thing, vertical speed also S1 it sees it did not do. It will apply the kinetic program which following presents from two player all preceding researches and secondary experiment after training it will lead and the improvement of technique it will be able to expect.

논문(論文) : 두 가지 브레스트-리토프스크 조약과 우크라이나 독립에 나타난 민족자결론의 전개

in early 1992, a series of Ukrainian parliamentary measures established the symbolic rupture between the new state and the Ukrainian SSR by adopting the state symbols associated with the Ukrainian People`s Republic. Its independence was proclaimed by the Central Rada just before the Treaty of Brest-Litovsk, a separate peace treaty, which was signed on Feburary 9, 1918 by the Ukrainian representatives and Germany. This treaty was a significant event in the history of Ukrainian nationalism, as only a fully independent state could conclude an international treaty. Soviet Russia, which also signed a separate treaty on March 3, 1918 at Brest-Litovsk, was forced to recognize the Ukrainian People`s Republic. Two treaties of Brest-Litovsk are, therefore, to be analyzed in this work, which brings into focus Ukrainian nationalism and self-determination. The latter, in particular, had been exploited fully during the World War I to disintegrate Russian Empire by Germany and Bolsheviks alike. The failure of the Ukrainians to achieve permanent independent statehood during the upheaval caused by World War I was, in large measure, a result of the underdevelopment of the national movement. Ukrainian lacked a substantial middle class despite considerable economic development. The Ukrainian national movement hardly evoked widespread response either from the peasant or from the industrial worker. It remained the creation of a small but devoted band of intellectuals drawn predominantly from the teaching and literary professions. The movement, lacking any sold support at home, was compelled to seek foreign patronage, turning unwillingly to Germany since Brest-Litovsk peace and to Poland after the defeat of the former in opposition to Soviet Russia.

The purpose of this study was to examine the biomechanical factors during the golf driver swing in major phases and to provide insight into the efficient swing movements for golf professionals. Four male collegiate golfers performed swings with a driver while foot pressure was measured. At address, the subjects’ weights were distributed evenly between feet or slightly more on the right foot. During the backswing, their weights progressively moved into the right foot until the top of the backswing. During the downswing, the weights started moving back to the left foot. After the impact and finish, all the weights moved to the left foot. During a driver swing, the center of pressure movements in right to left and front to back directions were not consistent among subjects but all the movements indicated facilitation of weight transfer and usage of the ground reaction force.

The study presents an easy and effective method for obtaining kinematic data with the use of inertial sensor for verifying the effect of the snowboard training protocol. One experimental subject who was intervened with snowboard protocol, whereas, three subjects participated as a control group in the study (n=4). Kinematic variables, i.e. ROM of knee joint, trunk inclination angle and maximum acceleration of COM were calculated with the data obtained from inertial sensors. Also, EMG was used to calculate lower limbs MVC ratio. Comparison of the Pre-Post results showed reduced values in both kinematic variables as well as lower limbs MVC ratio. It is considered that the measurement conducted immediately after the competition on the subject might have affected the lowered the values.
