임비오 한국운동역학회 2001 한국운동역학회지 Vol.11 No.3

The purpose of this study was to establish and compare kinematic data among four groups of collegiate soccer players who kicked the inside left kick, inside right kick, instep left kick and instep right kick. Twenty-four kinematic parameters were measured for 8 collegiate soccer players. Approximately 62.5% of these parameters showed significant differences among the four kick variations. Among the kinematic variables that showed the significance in statistics were the angle of running, the angle of final support foot, the angle of pelvis tilting, and so on. In angle of running, instep kick was the great more than inside kick. Also, right direction of kick was the great more than left direction of kick. In left direction of inside kick and instep kick, the final support foot were located left side. At ball impact the right direction of inside kick had the greatest pelvis tilting angle. Understanding kinematic differences can help a soccer kicker select and learn different kick drills and can help a goalkeeper learn how to predict the kick direction.

본 연구의 목적은 다운증후군 보행에 영향을 주는 근력 훈련이 성장기에 있는 다운증후군 아동의 지면반력의 변화에 미치는 효과를 살펴보는 것이다. 본 연구의 대상자는 삼염색체 다운증후군을 가진 남자 아동(11세~13세) 8명이며, 근력훈련 전에 지면반력 변인(수직력, 전후력, 좌우력, 총압력중심)을 측정하였으며 근력훈련 후에도 동일한 방법으로 지면반력 변인을 측정하였다. 지면반력 변인의 측정은 2대의 AMTI 지면반력기를 사용하였으며, 초당 100Hz로 데이터를 수집하여 분석하였다. 근력 훈련은 하지 근육 강화 훈련 4종목(스쿼트, 레그 컬, 레그 익스텐션, 토 레이즈)과 복근 및 척추기립근 강화 훈련 2종목(하이퍼 익스텐션, 윗몸 일으키기)으로 구성하여 8주간 주당 3회, 1회 운동 시 10~15RM×3세트로 점증부하 원리에 의거하여 실시하였다. 본 연구를 통한 결론은 다음과 같다. 근력 훈련 전후의 수직력, 전후력, 좌우력의 변화패턴은 다운증후군 아동별로 다양하게 나타났으며, 근력훈련으로 정상인과 비슷한 패턴으로 향상되었다. 또한, 훈련 전 · 후의 총압력중심의 이동궤적은 연구대상자별로 다양한 이동궤적이 나타나서 명확한 설명을 하기가 어려우며, 이에 대한 보다 종합적인 후속 연구가 필요할 것으로 사료된다. 본 연구를 통하여 다운증후군 아동들의 보행의 운동역학적 기전의 이해와 운동학적 결과의 해석을 돕고 향후 병적 보행의 평가에 대한 기초자료를 제시할 수 있을 것으로 사료된다. The purposes of this study were to investigate the effects of strength training on the change of ground reaction force for the children with trisomy 21 Down syndrome. The subjects of this study were consisted of eight elementary school students with Down syndrome who participated in the strength training. The strength training was administered by six items such as squat, leg curl, leg extension, toe raise, sit-ups, and hyperextension. For strengthening muscle, each group also was treated by walking for 8 weeks, three times a week, 10-15RM, 3sets, which was based on the principle of progressive overload. For inquiring the effect of strength training, the ground reaction force variables were measured in two phases : before-training and 8 week-after training. The gait of each subject was acquisition using 2 AMTI force platforms set at 100 frequency. The results of this study were as follows: The pattern of vertical, antero-posterior and modio-lateral forces, trajectory of net COP and the timing ratio of reaching the each events were shown variously. So, it is not easy to explain these variables clearly. As the result of strength training, these variables were changed. However, the results of within subjects differ greatly, there was no difference statistically.

Korean Journal of Sport Biomechanics Vol. 13, No. 1,pp. 109-119.'2003 Korean Society of Sport Biomechanics proceedings. The purpose of this study was to investigate differences of the mechanical efficiency of the characteristics of the basketball wheelchairs(cambers & size of the handrims). Nine mechanical efficiency on the characteristics of the basketball wheelchairs(cambers 7 size of the handrims). Nine healthy and normal wheelchair basketball players who had no impairments to their upper extremities were volunteered to participate in this study. VO_2 was collected using automatic gas analyzer(vmax29). Gross efficiency, net efficiency and work efficiency were analyzed from the calculated external power output and energy expenditure. The results were followed. First, gross efficiency in the basketball wheelchairs was observed across the range form 4 to 10%. Gross efficiency in this study showed less values than that from the literature reviewed in the arm cranking(15%), racing wheelchair(above 30%), gait(27%) and cycling(18-23%). Second, the small size of handrim(61cm) at the 16 degrees of camber produced higher efficiency values than the large size of handrim(66cm) whereas the different sizes of handrim at the 20 degrees of camber did not show any pattern. Third, both faster speed(1.11㎧→1.39㎧) and increase in treadmill inclination produced increases in energy expenditure. The results of this study may provide not only better understanding of the mechanical efficiency with adequate camber degree and proper size of handrim but also fundamental information for manufacturing the wheelchair.

The purpose of this study was to compare two putting styles in direction and distance by analyzing the results of the statistical analysis. One style was a performed by conventional putter, the other style was performed by a newly manufactured putter. A conventional putter was performed in frontal plane and A newly manufactured putter was performed in sagital plane. Six expert and sixteen novice subjects executed thirty times per putter and distance as accurately as possible, in order to reach a target distance of 4 and 7 m. The distance at which the balls stopped away from the cup was measured and analyzed statistically. According to statistical analysis, in distance, the style which performed in sagital planes was better than the style which performed in frontal planes in novice and expert. Therefore, the traditional method of putting may not be the best technique for golfers; other methods such as using a newly performed styles may be more effective.

기업이 실시하고 있는 다양한 마케팅 방법 중의 효과적으로 알려진 로열티 프로그램에 대 한 정의와 실시된 배경과 그 과정 그리고 현재까지의 발전된 모습을 통해 소비자에게는 실 용적이고 쾌락적인 혜택을 준다는 것이 확인되었으며, 기업에게는 포화된 시장에서의 고객 과의 관계를 유지시키며 이 관계에서 더 나아가 새로운 고객을 확보하는데 영향을 주고 있 음을 알았다. 그러나 모방이 되기 쉽고 단기적인 영향을 끼치며 높아지는 소비자의 기대를 충족시키기에 문제가 있다는 점에서 장기적인 관점과 더불어 세분화된 시장에 전략적으로 접근하는 노력이 필요하며, 각 분야의 협력을 통해 구체적인 방안을 마련해야함을 조언한다.

Fatigue characteristics of Pb ( Zr , Ti ) O3 capacitors on donor doping

(Bee Lyong Yang) 한국열처리공학회 2002 熱處理工學會誌 Vol.15 No.3

N/A Fatigue characteristics of ferroelectric Pb(Zr,Ti)O_3 (PZT) based capacitors through donor doping is reported in this paper. La substitution up to 10% were carried out to study systematically the fatigue behaviors of epitaxial ferroelectric capacitors grown on Si using (Ti_0.9Al_0.1)N/Pt conducting barrier composite. Ferroelectric capacitors substituted with 10% La show sufficient low voltage switched polarization and fatigue free performance. Systematic decrease in the tetragonality of the ferroelectric phase (i.e., c/a ratio) results in the corresponding reduction in coercive voltage, sufficient remnant polarization at 1.5-3V, and good fatigue property.
