In this study, we investigated a lower limbs muscle activity during body weight support treadmill training (BWSTT). Informed consent was obtained from 16 healthy men. Experimental system consists of force plate, treadmill, three-dimensional motion analysis system, electromyograph, and body weight support device. Body weight support (BWS) was set every 15% increase from 0% to 45%. Walking speed was...
We describes a feasibility study of the hybrid functional electrical stimulation (FES) walking assistive system, which is based on the fundamental principle of passive walking.
In summary, the core design of B-trees has remained unchanged in 40 years: balanced trees, pages or other units of I/O as nodes, efficient root-to-leaf search, splitting and merging nodes, etc. On the other hand, an enormous amount of research and development has improved every aspect of B-trees including data contents such as multi-dimensional data, access algorithms such as multi-dimensional queries,...
Online index functionality allows concurrent queries and updates during index maintenance tasks, e.g., creation of a new secondary index. Nonetheless, index operations can be both extremely resource-intensive and also extremely long-running. As such, necessary system activities such as adding a new secondary index or changing the primary index may introduce significant contention for resources such...
One of the most challenging aspects of managing a very large data warehouse is identifying how queries will behave before they start executing. Yet knowing their performance characteristics - their runtimes and resource usage - can solve two important problems. First, every database vendor struggles with managing unexpectedly long-running queries. When these long-running queries can be identified...
An importance of wearable devices in the field of medical treatment such as nursing care and rehabilitation has been strongly recognized. Also, the development of the power assisted device has been done to support the nursing care work for the elderly. The purpose of our study is to develop a flexible displacement sensor and bending sensor which can measure the movement of human body, flexible actuator...
Indium-tungsten-oxide (IWO) films were prepared by dc magnetron sputtering at ambient substrate temperature (Ts). Characteristics of the films were compared with those of In2O3–SnO2 (ITO) thin films prepared under the same condition. The sputter-deposited IWO films have entirely amorphous structure with an average transmittance of over 85% in the visible range and exhibit a minimum resistivity of...
Growth habit, heading date and Vrn genotypewere examined for wheat landraces cultivated in China,Korea and Japan, to study their ecogeographicaldifferentiation in east Asia. Spring type landracesaccounted for 43.6% of the whole, and the frequencyvaried between the localities, being closely relatedto the degree of winter coldness. Spring typelandraces mainly adapted to north and south Chinawhere average...
A 1,25-dihydroxyvitamin D [1,25-(OH) 2 D] deficiency and immobilization-related increased serum calcium concentration have been observed in hemiplegic stroke patients. To elucidate the influence of increased serum calcium concentration on bone metabolism, we measured serum biochemical indices and bone mineral density (BMD) in the second metacarpals of 170 elderly subjects with hemiplegic stroke...
Significant reduction in bone mineral density (BMD) occurs in stroke patients on the hemiplegic and contralateral sides, correlating with the degree of paralysis and vitamin D and K deficiency due to malnutrition, and increasing the risk of hip fracture. We evaluated the efficacy of vitamin K 2 (menatetrenone: menaquinone-4; MK-4) in maintaining BMD by comparing serum biochemical indices of...
A new quantum structure of AlGaAs laser for high temperature operation has been demonstrated. The new laser has a multiple-quantum barrier (MQB) structure located in the middle of the active region. This location of the MQB improves the efficiency of the hole injection into the active region compared to conventional MQB structure. It also maintains the suppressible effect of the electron overflow...
