Objectives: Neurological examination on balance function is widely applied in clinical practice. Balance function may be clinically relevant to an assessment of yinyang balance in such therapies as temporomandibular joint balancing medicine. Fukuda stepping test is a relatively not-well-known method of balance function test. This study reviewed the procedures and criteria of Fukuda stepping test. Method: Recent articles on Fukuda stepping test were searched in public database (Pubmed, Proquest) and reviewed for its procedures and clinical implications. Results: Fukuda stepping test adopts 50 steps or 100 steps with subsequent assessment of the deviation or displacement of the subject. It may not be reliable during acute phase. Conclusion: Fukuda stepping test may be utilized and be further developed to assess balance function in the neurological management of functions.

PURPOSE: The Fukuda test can be used at home and in school to diagnose scoliosis at an early stage and prevent serious curvature of the spine. This study aimed to use the Fukuda test to detect scoliosis. An additional aim was to invoke the national interest in imbalanced postures and habits, which result in scoliosis, by providing data obtained in periodic assessments. METHODS: The study consisted of 35 idiopathic scoliosis patients (22 in right lumbar spinal region and 13 in the left lumbar spinal region). The distance of displacement and angle of displacement were measured following the Fukuda test. A correlation analysis was then used to examine the distance of displacement and angles of displacement and rotation with regard to the direction of the curve in scoliosis. RESULTS: There was a significant negative correlation (p<0.00) between the direction of the curve in scoliosis and the angle of displacement, but there was no correlation between the cobb's angle and distance of displacement or between the cobb's angle and angle of rotation. CONCLUSION: The Fukuda test did not capture changes in spinal curvature such as the cobb's angle, or subsequent changes in the muscles. Thus, the Fukuda test is not suited to examining the direction or status of the thoracic curve in scoliosis patients. Simple methods to objectively measure scoliosis need to be developed.

본 연구의 목적은 교합안정장치의 착용이 신체의 균형에 미치는 영향을 알아보기 위함이다. 연구 대상자는 교합과 저작계에 이상이 없고, 보행에 지장이 없으며, 악관절의 병력을 가지고 있지 않은 10명을 대상으로 하였다. 신체 균형은 Fukuda stepping test, Stability of limit test를 이용하여 측정하였으며, 교합안정장치 착용 전과 착용 후의 유의성을 검정하기 위하여 Wilcoxon signed test를 실시하였다. 통계학적인 유의성을 검정하기 위한 유의수준 ${\alpha}$는 .05로 하였다. 연구 결과 교합안정장치 착용 전과 착용 후에 Fukuda stepping test의 이동거리와 Stability of limit test에서 유의한 차이가 있었다(p<.05). 본 연구의 결과를 통해 교합안정장치의 착용은 신체 균형에 긍정적인 효과가 있음을 알 수 있었다.

We developed the copper core ball electroplated with Sn-Ag-Cu of the eutectic composition which used mostly as Pb free solder ball with high reliability. In order to search for the practicality of this developed copper core ball, the evaluation was executed by measuring the initial joint strength of the sample mounted on the substrate and reflowed and by measuring the joint strength of the sample after the high temperature leaving test and the constant temperature and the humidity leaving test. This evaluation was compered with those of the usual other copper core balls electroplated with (Sn,Sn-Ag,Sn-Cu,Sn-Bi) and the Sn-Ag-Cu solder ball.

Background: The purpose of this study was to investigate the effect of a complex exercise program for elderly people who had experienced a fall on their balance ability and proprioception when their visual sense was blocked. Methods: The subjects were 24 elderly people with experienced fall. They were equally and randomly divided into a blind group and a general group. The subjects performed the complex exercise program for 30 minutes, twice a day, five days a week for 4 weeks a total of 20 times. Outcome measures were the 10-meter walking test (10MWT), Berg balance scale (BBS), Fukuda stepping test(FST), proprioception test (PT). Results: After the intervention, the blind group showed improvements in 10MWT, BBS, FST, PT. The general group showed improvements in 10MWT and PT. Conclusions: The complex exercise program for elderly people helped enhance their balance ability and proprioception.

Communication device to use slight movement for serious disabled is proposed. This device is developed mainly for patients suffering from ALS or a cerebral infarction. They often have communication difficulty because of deterioration of muscular functions. Features of this device are that the device is wearable on the user’s body and that it detects the movement of eyebrow. Because of these features, it is quite easy to install the sensor on the patient’s body, not like the conventional sensors. Furthermore, an adaptive communication software is incorporated. A feature of this software is that the arrangement and size of the button and window on the display can be optimized depending on the user's physical ability. In the field test it is confirmed that the communication device developed in this study is successfully helped the people with disability for increasing their communication ability.

A high strength aluminum alloy bolt (A7050, T7 temper treatment) has been developed by the authors. The bolt has a small grain size in the whole area of the bolt because of the large equivalent strain followed by thermo-mechanical treatment. As the bolt made of A 7050 has a risk of stress corrosion cracking, each grain should be strengthened the grain inside than the grain boundary in order to improve the stress corrosion cracking resistance. It has been confirmed that the nano-indentation hardness at each grain inside increased with the increasing equivalent strain by thermo-mechanical treatment processing.

Purpose: The purpose of this study was to investigate the effects of lumbar stabilization exercise on balance ability in patients with adolescent idiopathic scoliosis. Methods: This study was one group pretest-posttest design. Twenty young idiopathic scoliosis patients were recruited for this study. They had the lumbar stabilization exercise program for 40 minutes a day, three times per week for 3 weeks. The lumbar trunk muscle endurance test and clinical balance tests (functional forward reach, functional lateral reach, Fukuda 50-stepping, one leg standing with eyes open and eyes closed) were measured before and after the lumbar stabilization exercise. Results: There were significant differences between pre-and post-test in absolute value of the difference between right and left lateral reach, distance of Fukud 50-stepping and one leg standing on the each side with eyes closed(p<.05). The results showed that the lumbar trunk muscle endurance significantly increased(p<.05). Conclusion: In this study indicated that the lumbar stabilization exercise was effective on balance ability and lumbar trunk muscle endurance in patients with young idiopathic scoliosis.

Electrorheological(ER) fluid is a kind of smart material with variable shear stress and dynamic viscosity under various electric field intensity. Electric field can control the damping characteristics of ER damper. The objective of this study is the analysis of the performance of ER damper and its application to shock absorber. Idealized nonlinear Bingham plastic shear flow model is used to predict the velocity profile between electrodes. Cylindrical dashpot ER damper with moving electrode is constructed and tested under various electric fields. The analytic and experimental results for damping force are compared and discussed. Drop test system using ER damper is prepared to identify transient vibration characteristics. The rebound is eased as the applied electric field increases. When semi-active control algorithm is applied, rebound phenomenon disappears and vibration energy level decays faster than the case of zero electric field.
