The purpose of this study is the effects of 12 weeks complex training using swiss ball and elastic band on senior fitness and sarcopenia index in elderly women. The subject of this study was classified into exercise group (n=13) and control group (n=14). EG were carrier exercise program with swiss-ball and elastic band by 3 times a week, 3sets, RPE 11-13, and 60 minute. Test variables of among this study, senior fitness which is muscle strength, endurance, flexibility and dynamic balance and age-related sarcopenia index were muscle strength, muscle mass and short physical performance battery (SPPB). The results of this study were not significantly improvement at muscle strength, cardiopulmonary and flexibility but dynamic balance was significantly difference. And SPPB were significantly difference. In conclusion, the complex whole body training had positive effects on dynamic balance and SPPB of the elderly women.

The purpose of this study was to find out how Accumulation of Short Duration exercises influence on expression of apoptosis genes in a mouse skeletal muscle. The subjects, ICR-type mice, were divided into three cohorts, Accumulation of Short Duration exercise group, continuous aerobic exercise group, and control group. Accumulation of Short Duration exercise group performed wheel-running for fifteen minutes respectively in the morning and afternoon three times a week. Continuous exercise group performed wheel-running for thirty minutes three times a week. Both split and continuous groups completed the wheel-running trials for sixteen weeks. To identify the difference of apoptosis expression between groups, the data colleted from the skeletal muscle were analysed by one way ANOVA. Analyses of the data revealed that significant differences of apoptosis concentration in both continuous and Accumulation of Short Duration exercise groups, there was a notable differences were observed in control group.

이 글에서는 지금까지 대부분 기계 제품을 만들고 발전시키는 데 사용되어 왔던 기계공학 지식이 우리 인체의 움직임을 연구하는 데 어떻게 쓰일 수 있는지 한 가지 연구 주제를 예를 들어 설명하였다. 재료역학 이론을 바탕으로 만들어진 요추 모델을 통해 외부힘과 상체의 각도에 따라 각 요추의 움직임이 어떻게 달라지는지 알아보았다.

견관절은 우리 몸에서 가장 넓은 운동 범위를 나타내는 반면, 가장 불안정성한 구조를 가지고 있는 관절이다. 견관절을 이루는 해부학적 구조물들은 견관절 운동에 관여하지만 안정성 유지에도 기여하는 역할을 한다. 다음은 견관절을 구성하는 해부학적 구조물들을 주로 기능과 병리 측면에서 알아보고자 한다.

본 연구는 하퇴의지 착용자와 정상 성인간의 시간-거리, 운동형상학 변수를 조사하고 비교하기 위하여 실시하였다. 연구 대상자는 외상으로 인한 하퇴 절단자로서 내골격식 하퇴의지를 착용하고 독립적으로 보행이 가능한 20명과 연령, 신장으로 짝짓기한 대조군(matched control group) 20명이 참여하였다. 보행분석은 Vicon Clinical Manager Software (VCM)를 내장한 PC에 5개의 카메라가 연결되어 있는 Vicon 512 Motion Analysis System (MAS, Oxford Metrics Inc.)을 이용하였다. 하퇴의지 착용군의 단하지 지지시간이 정상 성인군에 비해 유의하게 짧았으며(p<.05), 하퇴의지 착용군에서 슬관절의 선전이 증가되었으며 족관절의 저측굴곡이 감소되었다(p<.05). 하퇴절단자들의 보행개선을 위해서는 하퇴절단자 개인의 보행능력에 알맞은 부품의 선택, 체계적인 보행훈련 및 평가, 보행능력 향상을 위한 근력강화 프로그램 등 체계적인 재활훈련 프로그램이 필요한 것으로 사료된다. 본 연구는 연구대상자의 수가 제한되어 있으므로 연구의 결과를 일반화하기에는 제한점이 있으나, 향후 편측 하퇴절단자의 보행연구에 대한 기초 자료로 사용될 수 있을 것이라고 생각된다.

Chemoenzymatic method was used in this study to evaluate the quality of cultured red seabrim. Level of ATP related compounds, ATPase and Adenylate energy charge (AEC) well reflected changes in condition of fish. ATP level in the muscle of exercised cultured red seabream was decreased significantly during cultured period. In contrast, the level of ADP in the muscle was increased during the period. Level of ATP related compounds in the muscle of cultured red seabream without exercise didn't show significant difference compared to the exercised group. AEC value in muscle of cultured red seabream without exercise was 0.89$\pm$0.02, while AEC value of the exercised group was 0.88$\pm$0.04. ATP and AEC levels among different size of fish did not show any significant difference. AEC value in all sample was higher than 0.8, indicating that the condition of cultured fish was healthy. Activity of Mg2$^{＋}$ (＋Ca2$^{＋}$), Mg2$^{＋}$ (-Ca2$^{＋}$) and Ca2$^{＋}$-ATPase during culture period did not change significantly, regardless of exercise. Therefore, the AEC appears to have some validity as fish health indicator.

The purpose of this study was to investigate the changes of body composition, serum lipids and several parameters of body fatness (percent body fat, waist-hip ratio) in abdominal women by exercise. For this study, 8-weeks intensive exercise(5km jogging/day, 50min/day) was continued by subjects and they limited only fat rich foods and controlled daily energy intake to 1,800kcal～2,100kcal per day. The subjects were 52 women and the distribution of ages was 36～54 years. The data were analyzed using SPSS/PC package program and the results were estimated by paired t-test, Pearson correlation. The results are summarized as follows : 1) After exercise-training for 8 weeks, percent body fat, body mass index, body weight, total cholesterol was decreased (p<0.05). 2) LDL cholesterol and triglyceride was decreased significantly(p=0.000). The changes in deep abdominal adipose tissue were related to changes in triglycerides. 3) After exercise training, the waist-hip ratio was significantly correlated to body weight and serum lipids. 4) According to the data of this study, Ⅰ recommended that obese women, especially, abdominal obese patients should exercise regularly and we should prolong many studies for obesity.

This paper investigates the kinematic and dynamic analysis of a spherical three degree of freedom parallel joint module, which is used in the exercise equipment for balance and leg-strength improvement of aged people. The joint module has three dyads which consist of two links and three revolute joints, and their all joints intersect at the global point located at the module's center. The paper shows the explicit mathematical procedure for deriving the closed form solutions in the inverse and forward position analysis of this parallel joint module. In velocity and acceleration analysis, we derived relations for joint velocities and accelerations of dyads and rotational velocity and acceleration of the top plate. For applying this module to rehabilitation exercise, we determined the dynamic model of the Korean males in their 50s and examined the model's results by dynamic model simulation.

Controlling fluid flows in micro scales is a non-trivial issue among those who are involved in designing lab-on-chips. Pumping and mixing by using electrokinetic principles has been popular in that the method requires a few parts and it is easy to control. This paper explains the basic mechanism of the electroosmotic flows caused by AC together with presenting some numerical results. In particular, the fundamental, physical idea involved in the mechanism will be illustrated in terms of the kinematic aspect. Since the electroosmotic flows are mainly driven by the motion of ions, we also demonstrate the ion motions by using the numerical-visualization method.

본 논문에서는 파킨슨병이 우리 사회에서 증가하고 있고 노인들 만이 아니라 젊은 사람들에게도 나타날 수 있기 때문에 환자들을 위해 근 기능 및 인지능력을 향상 시키는게 목표이다. 파킨슨병은 현재까지 원인이 알려지지 않았지만 도파민 세포가 손상되는 것으로 알려져 있기 때문에 아직은 약물치료와 식이요법 치료를 통해 질환의 증상을 중지시키거나 느리게 할 수 없다. 파킨슨병의 증강 중 가장 중심이 되는 근 기능 문제와 인지능력을 동시에 향상 시킬 수 있는 기대를 할 수 있으며 이것을 통해 다른 증상들도 느려 질 수 있도록 하는 기대를 할 수 있다. 프로그램을 통한 근 기능 능력이나 인지능력을 동시에 향상하고 대상자 개개인의 능력에 맞게 운동을 할 수 있는 프로그램을 개발하는데 목적이 있는 연구이다.
