Background: Stroke is a neurological disorder characterized by an impaired static balance. A change in poor posture after stroke may worsen static balance. The balance control through an upright posture may include kinesiology taping of the middle back. Objectives: To investigated the effect of kinesiology taping of middle back on static balance in patients with stroke. Design: A randomized controlled trial. Methods: A total of 10 patients with stroke were divided into two groups. The experimental and control groups received kinesiology taping and placebo taping of the middle back, respectively. After 24 h, static balance (i.e., sway area and path length) was measured in closed eyes condition. Results: The experimental group (kinesiology taping group) showed a significant decrease in sway area and path length after the intervention. In addition, kinesiology taping group showed a significant decrease in sway area and path length compared to the control group. Conclusion: Kinesiology taping of the middle back can improve static balance in stroke patients.

This paper describes a detailed simulation model of the static condenser (STATCON) to analyze the dynamic interaction with the ac transmission line. The static condenser was represented by a 12-pulse voltage-source inverter sharing an energy storage dc capacitor. The voltage-source inverter consists of two 6-pulse bridges modeled with ideal gate-turn-off switches. The control system for the static condenser was designed through a mathematical model deduced from the equivalent circuit. Simulation results show that the conceived model is very effective to analyze the dynamic interaction between the static condenser and the ac transmission system.

Numerical analysis of slope stability is presented using slice method, static seismic analysis methods, and earthquake response analysis methods. Static seismic force is considered as 0.2g while vertical static seismic force is not considered in analysis. For earthquake response analysis, Hachinohe-wave is applied. Safety factor calculated using slice method for failure surface. Calculating methods are Bishop's method and Janhu's method. Static seismic analysis was applied using Mhor-Coulomb model and earthquake response analysis was applied using non-linear elastic model.

The problem of controlling static gaits for a quadruped walking robot is investigated. A theoretical approach to gait study is proposed in which the static stability margins for periodic gaits are expressed in terms of the kinematic gait formula. The effects fo the stride length on static stability are analyzed and the relations between static stability and initial body configurations are examined. It is shown that the moving velocity can be increased to some extent without affecting stability margins for a given initial body configuration. Computer simulations are performed to verify the analysis.

Static inverters are essential devices onboard of rolling stock. State-of-the-art static inverters have an impact on both rail infrastructure and vehicle maintenance due to their new topology with new features. The paper describes two important aspects as examples of new features available in state-of-the-art static inverters: active input current control and the effects on the rail infrastructure as well as the detection of the state of charge and the state of health of batteries to simplify vehicle maintenance.

In this short paper, we investigate the existence of non-trivial almost Ricci solitones on static manifolds. As a result we show any compact nontrivial static manifold is isometric to a Euclidean sphere.

성범죄자의 재범 우려가 큰 가운데 특정 성범죄자들은 다른 성범죄자들에 비해 재범하는 경향이 더 높은 것으로 알려져 있다. 이에, 연구자들은 성범죄자의 재범을 예측하는 요인들을 규명하기 위해 노력해왔다. 본 연구에서는 현재 교정시설에서 사용하는 STATIC-99(정적 위험 요인 평가)와 HAGSOR-동적요인을 사용하여, 각 도구의 재범 예측력을 분석하였다. 분석 결과 STATIC-99와 HAGSOR-동적요인은 통계적으로 유의한 재범 예측력을 가진 것으로 나타났다(각각 AUC = .737, AUC = .597, ps < .001). 그러나 성범죄 재범에 대해서는 STATIC-99만 통계적으로 유의한 예측력을 보였다(AUC = .743, p < .001). 또한 HAGSOR-동적요인을 추가한 Model의 재범 예측에 대한 설명력은 STATIC-99만을 투입한 Model보다 통계적으로 유의한 수준에서 증가하는 것으로 나타나(∆χ² = 12.721, p < .001), HAGSOR-동적요인의 증분적 재범 예측력이 확인되었다. 그러나 성범죄에 대한 증분적 재범 예측력은 확인되지 못하였다. 재범 위험성 평가 항목 중 정적 위험요인은 친족피해자를 제외한 모든 항목이 재범을 유의하게 예측하였으며, 동적 위험요인 중 범죄적 성격, 대인관계 공격성, 사회적지지(부족)이 재범에 영향을 미치는 것으로 분석되었다. 결과에 대한 함의와 현장에서 도구의 사용 문제, 개선 방향 등이 추가로 논의되었다.

Objective : The purpose of this study was to investigate the effect of sensory stimulation for static balance on normal children. Sensory input was consisted of colors, and music tempo stimulation. Methods : Participants were consisted of 20 normal kindergarten children ranging in age from six to seven years. The static balance was tested by a BPM(Balance Performance Monitor). In this study one-way ANOVA was used and the statistical significance level of results was determined at 0.05. Results : 1. According to color stimulation, there was no significant difference in static balance among red, yellow, green(p>0.05). 2. According to music tempo stimulation, there was no significant difference in static balance, among the high music tempo and low music tempo children in a general environment(p>0.05). 3. However, both green color and low music tempo stimulation have a little effect on static balance on normal children. Conclusion : These results indicate the possibility that the application method of green color and low music tempo stimulation may help in the improvement of static balance for the disabled children. This study will be used as the foundational data of therapeutic environment for the disabled children.

The purpose of this study were to compare light touch, two-point discrimination, position sense, and static balance ability and to examine the relationship of static balance ability and different senses in those who are wearing various heights of high-heeled shoes. Each 29 women was classified two different heights (below 3 cm, above 7 cm) by experience in wearing shoes. A t-test was used to determine the differences between low- and high-heeled shoe in light touch, two-point discrimination, position sense, and static balance ability. Pearson correlation was used to examine the relationship of static balance ability to these sensation. The results were as follows: 1) No significant differences in average light touch, position sense between two groups were found(p>0.05). But significant differences in average two-point discrimination, static balance ability were found(p<0.05). 2) Static balance ability was not significantly correlated with light touch, position sense, two-point discrimination(p>0.05). The results suggest that long time experience in wearing high-heeled shoe may be caused local sensory change and decreased static balance ability. Even though, static balance ability was not significantly affected but correlated with two-point discrimination, position sense, and light touch in order.

An aluminum suspension corner module is widely used in high class passenger cars to reduce vehicle weight and improve fuel economy. According to the change of material and suspension type, the evaluation of the static strength and failure mode of the corner module is important. In this study, static strength and failure mode analysis of aluminium multi-link suspension corner module is presented. Static strength test system is designed and static failure mode tests of the corner module are carried out in longitudinal, lateral, and vertical direction. From the resuls of the tests we found that the failure modes are different compare to those of the steel corner module. The static failure modes and load-displacement curves of this study will be used as a guidance in design of a passenger car aluminium multi-link suspension corner module.
