  • The purpose of this study was to investigate the changes of kinetic and kinematic parameters in obstacle gaits after 12 weeks of an aquatic exercise program. Eight female elders walked in four different heights of obstacles(0, 2.5, 5.1, & 15.2cm) on their self-selected speed. The ROM of hip was significantly increased after the aquatic exercise program. Swing and Stance duration were decreased. The step length was significantly increased and the step width was decreased. After the exercise program the clearance between the right foot and the top of obstacle(except 15.2cm) increased and the crossing speed was increased. The braking force, propulsive force, braking impulse, and propulsive impulse were significantly changed after the aquatic exercise program. The 12 weeks of the aquatic exercise program resulted in lower body strength and balance gains in female elders. The improvements were associated with changes in kinetic and kinematic parameters leading to an obstacle-crossing speed and a safer lower-limb control. The aquatic exercise program is suggested as an effective intervention to promote gait ability and prevent fall-related to the injuries.

  • In this study, examined are the characteristics of 'One Book, One City' reading campaigns conducted in Seattle. Chicago, and 'The Big Read', a nationwide 'One Book' campaign, supported by the NEA, in the U.S.A. and Seoul and Cheongju in Korea. Some differences as well as similarities were found in the goal setting, selection of books, strategies for reading and discussion, and programs of these 'One Book' reading campaigns. While, as a mass reading event, 'One Book' reading campaigns in various communities share the goal of promoting literacy and communication through reading and discussion, each 'One Book' campaign seems to show uniqueness in the criteria of book selection, reading and discussion guides, and the activities and Programs. which make up cultural contents.

  • A series of experiments has been performed to investigate the flapping motion, which has been generally considered as an intrinsic characteristic of plane flow, of the horizontal merging buoyant jet discharged into stationary ambient water. For Horizontal merging buoyant jets, the flapping motions has been observed and the average onsets of flapping motion coincided with the start of merging transition. The Strouhal number, which describes the measure of frequency of vortices on the flow boundary with respect to the local properties of the flow, varies and converges to a constant value over merging transition. Considering the merging transition and the variation of local flow properties, the characteristics of flapping motion of plane flow can be applied to merging buoyant jets.

  • Lesch-Nyhan 증후근(LNS)은 hypoxanthine guanine phosphoribosyle transferase(HGPRT) 효소를 암호화 하는 X 염색체가 불완전해서 일어나는 유전적인 추제외로계(또는 기저핵)의 드문 병변이다. 출생시 LNS 유아는 정상적인 운동발달이 관찰되어진다. LNS에게서 현저하게 진단적인 특징으로 보여지는 운동심리적 행동인 self-mutilating 행위는 4살 이후에나 나타난다. LNS 아이들은 오히려 초기에 Rett's 증후근, 뇌성마비, 자폐, 다운증후근과 유사한 운동행위를 보인다. 그래서 LNS 아이들은 앞에 기술한 신경학적 장애로 오진을 받을 수가 있다. 오진으로 인해 초기에 적절한 치료를 받지 못한다면 LNS는 결과적으로 합병증(신장부전)과 self-mutilating 행위로 인하여 치명적일 수가 있다. 그러므로, 이 연구의 목적은 LNS 평가 동안 더 나은 진단을 하도록 하기 위하여 LNS와 관련된 기능부전에 대한 지식을 임상가들에게 제공하고자 함이었다. 연구 대상자는 10살인 2명의 쌍둥이 남아이었으며 실험은 뻗기 과제 수행(reaching task)시 움직임 특성을 보기 위하여 운동형상학적과 비디오 분석을 사용하였다. 기술통계로 분석 결과 움직임 시간과 단위가 증가됨을 보였고 사지의 분절적 움직임이 협응되지 않음을 보였다. ballistic과 jerky 움직임 양상은 dysmetric과 비긴장성 운동 행위에서 우세하였다. LNS은 추체로계 운동 장애 (과근긴장도나 저긴장도) 와 추체외로계의 운동 장애(dystonia와 choreoathetosis)의 혼합된 형태를 보였다. 결론으로 이 연구는 운동발달 장애를 가진 아이들을 치료하고자 할 때 임상가들한테 LNS 아이들의 움직임 장애의 다른 진단적 특징을 알아야 한다는 것을 제시하고자 한다.

  • The purposes of this study were to examine whether aquatic exercise has influence on the neuroplasticity and vestibulo-motor function in diffuse brain injury rats. 80 Sprague-Dawley rats were assigned to four groups; Group I: control group (n=20), Group II: aquatic exercise (n=20), Group III: treadmill exercise with change of velocity and inclination (n=20), Group IV: simple treadmill exercise (n=20). And we applied exercise each groups for 3 weeks except Group I. Before the rats were sacrificed to identify immunohistochemistry study at each time of measurement day, Rota-Rod test was given to assess changes in vestibulomotor function. then, the immunohistochemistry study of GAP-43 in discrete regions of the rat brain was performed to measure changes in neuroplasticity. The results demonstrate that aquatic exercise group is more effective than other groups. expression of GAP-43 and vestibulo-motor function were increased most in aquatic exercise group. Therefore, this study suggest that aquatic exercise may effective therapeutic approach to increase neuroplasticity and vestibulo-motor function in traumatic brain injury.
