  • The control effectiveness and disturbance suppressibility are mainly governed by a left eigenstructure of a system. In this paper, a control algorithm which uses an output feedback eigenstructure assignment scheme is proposed in order that a desired closed-loop system has the specified degree of controllability and/or degree of disturbance suppressibility. To do this, a modal and a gross disturbance suppressibility measures are proposed. A modified version of Hamdan and Nayfeh's modal controllability measure is also presented. The validity and usefulness of the proposed measures and the controller design algorithm are illustrated by designing a controller for a third-order system as an example.

  • Purpose: This study examined the effects of spinal stabilization exercises using visual feedback on the gross motor function and balance of the sitting posture in children with cerebral palsy. Methods: The subjects were 18 children with cerebral palsy aged 8-15 years in the I-III stages of the Gross Motor Function Classification System. The subjects were divided into an experimental group (n=9) and control group (n=9). The experimental group was treated with 30 minutes of neurodevelopmental treatment and 20 minutes of spinal stabilization exercises using visual feedback. The control group was treated with 30 minutes of neurodevelopmental treatment and 20 minutes of spinal stabilization exercises without visual feedback. Both groups participated in the experiment twice a week for eight weeks. The Gross Motor Function Measurement was performed to evaluate the changes between pre- and the post-intervention in gross motor function. The Seated Limit of Stability Surface Area was measured to evaluate the changes in trunk balance. Results: Both experimental and control groups showed a significant increase in the gross motor function and trunk balance (p<0.05). The experimental group showed a significant increase in gross motor function compared to the control group (p<0.05). The experimental group showed a significant increase in the dynamic trunk balance in all directions when measuring the Seated Limit of Stability Surface Area (p<0.05). Conclusion: Spinal stabilization exercises using visual feedback for the neurodevelopmental treatment of children with cerebral palsy can improve their gross motor function and trunk balance when in a sitting posture more effectively.

  • Fashion business must reflect the seasonable fashion trend because fashion has change always, and therefore fashion business has a big risk at the attribute. Careful consideration should be given to the selection of a particular color code to meet the purpose of marketing research in various color products. It must be designed to grasp systematically and comprehensively the current trend of colors. The most suitable color code for meeting this proposition would be one based on the designation by color ranges. The ISCC-NBS method of designating colors, published in 1955, was established by dividing the color solid into 267 color name blocks. The detailed classification like the ISCC-NBS system is very appropriate to serve the purpose of giving all color names according to color ranges. But it is somewhat too complicated to answer the purpose of surveying the trend of colors and of comparing and evaluating the ups and downs in the popularity of the range of each individual color. I have worked out the most convenient method of designating colors in accordance with the type of investigation needed. It is the classification which involves four classification system in itself, fundamental, gross, medium, and minute. The fundamental classification system classifies hues and neutrals into 16ranges. The gross classification system divides the above 16 ranges into 30. The medium classification divides the above 30 ranges into 103 in terms of tones. The minute classification divides the above 103 ranges into 207 in terms of specipic hues.

  • Background and Objetive : Lack of uniformity in reporting facial nerve recovery in patients with facial nerve paralysis has been a major disadvantage in comparing treatment modalities. The objective evaluation of facial nerve function is a complex procedure. The House and Brackmann grading system, the Yanagihara grading system has been recommend as a universal standard for assessing the degree of facial nerve palsy. However, clinical studies for treatment of facial palsy have rarely used this universal standard in oriental medicine. That is the reason for analysing this facial nerve grading system. Material and Method : We choose 10 scales reported from 1955 till 1995. These facial nerve grading systems may be classified as Gross system, Regional system and Specific system. Result and Conculsion : The scales of Botmann and Jonkees, May, Peitersen, and House and Brackmann are the gross facial nerve grading systems with which we grossly assess the facial motor dysfunction and the secondary defect. Among these scales, H-B scale is the most widespred The scales of Yanagihara(若杉文吉), Smith, Adour and Swanson, Jassen, FEMA are the regional facial nerve grading system in which we weight, or unweight the facial motor dysfunction and the secondary defect. For example, the scales of Yanagihara(若杉文吉) and Smith are the unweighted regional scale, the scale of Adour and Swanson, Jassen, FEMA are the weighted regional grading system. The scale of Stennert is the Specific facial nerve grading system in which we respectively assess the grade of facial dysfunction at rest, in motion and the secondary defect. For the objective evaluation of the oriental medicine treatment for facial palsy, we must use the universal standard scale, i.e. the H-B scale, the Yanagihara scale.
