The Effects of an 8-Weeks Training on Postural Control for the Elderly
유창호,권대규,표용준,김경 한국정밀공학회 2014 International Journal of Precision Engineering and Vol. No.
This paper presented the 8-weeks training effects of training system based on an unstable platform and a visual interactive system for improving the ability of postural control. To confirm the effects of the training, fifteen elderly volunteers took part in a series of balance training using this system. Fifteen elderly volunteers as the control group compared with the training group. To evaluate the effects of the training, the relevant parameters such as the time of timed up and go (TUG) test, the transfer limits of the different directions, the sway path of center of pressure (COP), and the root mean square (RMS) of COP in anteroposterior (AP) direction and mediolateral (ML) direction, concentric isokinetic strength of ankle and knee joints were measured from pre-training to post-training. The results showed that the training system could successfully assess the gradual improvement of the postural control capability of the volunteers in the system and showed a possibility of improving balance capability of the volunteers. Moreover, the significant improvement in the postural capability of the elderly suggested that the elderly could benefit more from the training using the system for the improvement of the ability of postural control.

Objective : This study was performed to evaluate the treatment of Acupuncture therapy including Herbal Acupuncture theraphy and Korean Bee Venom Theraphy in Klippel-Trenaunay-Weber Syndrome. Methods : We treated 1 case of Klippel-Trenaunay-Weber Syndrome patient with mainly Korean Bee Venom Theraphy, and herbal Acupuncture, acupuncture theraphy from 27th August, 2001 to February, 2003. Results : After 3 weeks of Korean Bee Venom Theraphy, and herbal Acupuncture, acupuncture theraphy, a remarkable improvement was made for Klippel-Trenaunay-Weber Syndrome. Conclusions : Korean Bee Venom Theraphy and other acupuncture therapies were effective in reducing the symptoms. We think that it need the further study and clinical trial for Klippel-Trenaunay-Weber Syndrome.

In this paper, an overload detecting algorithm for an excavator is presented. The proposed overload detecting algorithm is based on the time series analysis especially correlation function. The main purpose of this paper is to prevent damage or crack from the fatigue loaded on an excavator in advance. Generally, the larger data, the longer processing time, and the amount of the data used in this paper are also large, especially every sampling period, 1600 data are gathered and calculated. So this paper focuses on minimizing the number of required sensors by using the correlation function. From the cross correlation function, similar pattern sensors are eliminated and dissimilar pattern sensors are considered, and from the auto correlation function, the overload can be detected. To prove the efficiency of the proposed overload detecting algorithm, this paper shows the computer simulation results.
