Background: To evaluate the influences of Eye movement program applied to elderly people on static balance. Methods: The subjects consisted of fourteen elderly people. The subjects were divided into two group. The control group (n=7) received no exercise and/or stimulation. The Eye movement program training (E/P) group (n=7) performed balance training using word card and batom. E/P group were accomplished during 4weeks (5 day/week, 60 min/day). All tests were completed before and after experiment. The static balance ability was measured by normal standing when eye open and close on good balance system, respectively. For each case, the experimental data were obtained in 3 item; mean X speed, mean Y speed and velocity moment. Results: The result of this study were as follows: 1. In E/P group, the statistically significants were shown on only mean Y speed in the case of normal standing when eye open (p<.05), but the statistically significants were not shown on mean X, Y speed and velocity moment in the case of normal standing when eye close (p>.05). 2. In control group, the statistically significants were not shown on all posture (p>.05). 3. There was a statistically significant difference on the mean Y speed and velocity moment in the case of normal standing when eye open between control group and E/P group (p<.05). Conclusions: The above results revealed that balance training using Eye movement program were partly effective for improving the static balance ability.

Modeling and system development for the fabrication process in the semiconductor manufacturing is presented in this paper. Maximization of wafer production can be achieved by the wafer flow balance under high utilization of bottleneck machines. Relatively simpler model is developed for the fabrication line by considering main characteristics of logistics. Simulation system is developed to evaluate the line performance such as balance rate, utilization, WIP amount and wafer production. Scheduling rules and input rules are suggested, and tested on the simulation system. We have shown that there exists good combination of scheduling and input rules.

Purpose: This is designed to study the effect of weight-support walking training through motor learning on motor functions of children with cerebral palsy, in particular their activity of daily living and balance. Methods: Thirteen children with spastic cerebral palsy, at gross motor function classification system (GMFCS) levels III~IV, underwent treadmill walking training. It used principles of weight support, 4 times a week for 7 weeks, 10 minutes at a time, before and after neurodevelopmental physical therapy. Everyday functions were measured using Functional Independence Measure for Children (Wee-FIM). The ability to keep their balance was measured using electronic measuring equipment from good balance system and the assessment was made before and after the experiment. Results: There were significant differences (p<0.05) between pre and post experiment levels of functional independence in everyday life, in self-care activities, mobility, locomotion and social cognition. With regard to changes in standing balance, there were significant differences before and after the experiment (p<0.05) in GMFCS level III. There was a reduction in the agitation velocity in the x- and y-axes which measures the left-to-right shaking; in GMFCS level IV, velocity moment was reduced. Conclusion: Walking training using a treadmill can help improve the everyday activity and balance in children with spastic cerebral palsy. It can also be served as a useful purpose as a method of intervention in pediatric care.

In this paper, sensor system and inspection algorithm in order to inspect steel balance weight for automobile is described. Steel balance weight is composed of clip and weight, which is joined by press process. The defective one has a gap between clip and weight. To detect whether there is a gap, sensor system is simply configured with laser line projector and USB camera, which make it possible to measure the height difference of clip and weight area. Laser line pattern which is made on the surface of a balance weight is captured by USB camera. In case that USB camera is used in machine vision, barrel distortion caused by wide angle lens makes the captured image distorted. Image warping function is applied to correct the distortion. Simple image processing algorithm is applied to extract the laser line information and whether it is good or not is judged through the extracted information.

Postural balance of temporomandibular joint (TMJ) reflects the neuromuscular balance. TMJ posture treatment for meridian yinyang balance has been asserted to have an impact upon cervical spine alignment with an episodic good clinical result for refractory torticollis cases. A retrospective study with one-group pretest-posttest design was conducted to review cervical spine imaging data and clinical symptom changes in cervical dystonia cases to explore the effect of TMJ balance treatment. Review of clinical symptoms and cervical spine imaging data including computed tomography and simple x-ray of 9 cervical dystonia cases revealed significant improvement of cervical spine alignment and clinical symptoms. Improvement of cervical spine alignment may be an underlying mechanism of TMJ balance treatment, as a way of balancing the whole-body meridian system.

본 연구는 수중과 지상에서의 장애물 훈련 프로그램이 만성 뇌졸중 환자의 균형에 미치는 효과를 비교하고자 시행하였다. 연구대상자는 수중운동집단(15명)과 지상운동집단(15명)으로 나누어 장애물 훈련 프로그램을 12주간 주 3회, 40분씩 실시하였다. 정적균형은 Good Balance System을 이용하여 눈을 뜬 상태에서 내 외측 동요속도와 전 후측 동요속도 그리고 동요면적을 측정하였고, 동적 균형검사는 기능적 팔 뻗기 검사와 일어나 걸어가기 검사를 이용하여 측정하였다. 그 결과, 두 집단 모두에서 정적 균형(내 외측 동요속도, 전 후측 동요속도, 동요면적)과 동적균형(기능적 팔 뻗기 검사와 일어나 걸어가기 검사)에서 유의한 차이를 보였고, 집단 간 차이에서는 모든 변수에서 수중운동군과 지상운동군 간의 유의한 차이를 보였다. 이상의 결과를 볼 때, 수중과 지상에서의 장애물 훈련이 만성 뇌졸중 환자의 균형 능력 증진을 향상시키며, 수중이란 환경에서의 훈련이 지상운동보다 유의한 효과가 있다는 결과를 알 수 있었다. 수중운동은 만성 뇌졸중 환자의 균형 능력 증진을 위한 방법으로 유용하다고 생각되며, 앞으로도 균형능력 증진을 위한 수중운동에 대한 연구가 활발하게 이루어져야 할 것으로 사료된다.

육상에서 석유 제품의 수송에 가장 많이 활용되는 방법이 송유관을 이용하는 방법이다. 그러나 누유 혹은 도유로 인한 대형사고 및 환경 재해의 위험이 있기 때문에 일반적으로 누유 감지 시스템 (Leak Detection System)을 활용하여 이에 대처하고 있다. 장거리 송유관에 많이 활용되는 방법은 저압확장파((Negative Pressure Wave)를 활용한 누유 감지 기법인데 저압확장파 기반의 시스템은 감지 성능이 뛰어나지만 높은 오알람 발생률로 인하여 누유 알람의 신뢰성이 저하되는 단점이 있다. 본 논문에서는 송유관 양단의 유량 차이 (Volume Balance) 비교를 추가로 활용하여 저압확장파 기반 누유 감지 시스템의 오알람을 필터링하는 알고리즘과 실험 결과를 제시한다.
