Mobile AGV is one of the nonholon-omic systems. The integration of the kinematic adaptive controller for the dynamic in this pa-per introduction a motion control problem's dynamic state feedback as well as output feedback tracking laws will be constructed with the adaptive extension of the controller is proposed. Feedback control strategies for mobile AGV are important to compensate for disturabances and errors in the initial condition. The problems of path following or tracking and of stabilization about a constant configuration have been treated as separate problems for nonholonomic mobile AGV.

This paper presents an adaptive finite element method for magnetostatic force computation using Maxwell's stress tensor. Mesh refinements are performed automatically by interelement magnetic field intensity discontinuity errors and element force errors. In initial mesh, the computed forces for different integration paths give great differences, but converge to a certain value as mesh division is performed by the adaptive scheme, We obtained good agreement between analytic solutions and numerical values in typical examples.

Objective : To explore the effect of intensive sensory integration therapy through daily camp programs for children with sensory modulation disorder. Methods : A comparison of quantitative data and qualitative description between before and after sensory integration therapy camp and main outcome measure was used, including MAP behavior checklist, JSI-2, COPM, sensory history, STEP-SI. Results : The adaptive response was increased and sensory modulation problems were observed less than before the camp. Conclusion : For this study a more diverse, extended and intensive SI program is considered necessary. Further study is needed to develop these findings.

Objective : To summarize and interpret observations of responses of child with sensory modulation disorder during four therapy sessions in order to contribute to future studies. Method : Analyze treatment goals and strengths and weaknesses of four therapy sessions and discuss implications of therapy. Results : Child's adaptive responses were improved throughout the therapy sessions. Conclusions : Intensive sensory integration therapy is needed continuously. Future study with this participant is needed to explore more effectiveness of sensory integration therapy.

Objective : To identify the effect of intensive sensory integration therapy through 5 days camp programs for children with dyspraxia Methods : A comparison of quantitative date and qualitative description between before and after sensory integration therapy camp described adaptative response of children and individual home-based program was designed and therapist educated parents about it. Results : The problem of control and apraxia which children have was improved rather than before camp and adaptive response increased. Conclusion : Follow-up study is needed to observe and investigate the effect of continuous treatment after camp participation.

Objective : Korean Academy of Sensory Integration(KASI) planned and executed sensory integration Therapy Camp to serve intensive sensory integration program for children with the sensory integrative dysfunction, to support their family with parent' education and home programs, and to suggest practical guideline for therapists through individual supervision and demonstrations. Methods : The camp was held during 5days in the children's center for developmental support that set up sensory integration tools. The camp executed the individual and group interventions that consisted of 7 children with sensory integrative dysfunction, especially dyspraxia and 7 therapists who manage them and 6 supervisors. Results : Children which served the intensive intervention showed the improved adaptive responses during the camp and their parents reported the satisfaction degree of the camp program was 83%. Their therapists also had a chance to understand the broader sensory integrative interventions through the supervision. Conclusion : To provide the clients for qualitative sensory integration service, the camp must be programmed that children with the sensory integrative dysfunction can service the intensive sensory integration program and their therapists can actually experience reeducation individually through supervision and demonstrations.

The high-order numerical method based on the adaptive mesh refinement(AMR) on the quadrilateral unstructured grids has been developed in this paper. This adaptive-grid method, originally developed with MUSCL-TVD scheme, is now extended to the WENO (weighted essentially no-oscillatory) scheme with the Runge-Kutta time integration of fifth order in spatial and temporal accuracy. The multidimensional interpolation was studied in the preliminary research, which allows us to maintain the same order of accuracy for the computation of numerical flux between two adjacent cells of different levels. Some standard benchmark tests are done to validate this method for checking the overall capacity and efficiency of the present adaptive-grid technique.

In this study, we present an approach for reducing the information inaccuracy of existing star aggregation based on bypass links when there are multi-constraint QoS parameters in asymmetric networks. In our approach, bypass links with low similarity are selected. Links that are not chosen as bypass links are included in each group depending on the star's link characteristics. Moreover, each link group is aggregated differently according to the similarity of the links that make up the group. The selection of a bypass link by using link similarity reduces the existing time complexity of O($N^3$) to O(N) by virtue of the simplification of the selection process. In addition, the adaptive integration according to the characteristics of the links in each group is designed to reduce the information inaccuracy caused by static aggregation. Simulation results show that the proposed method maintains low information distortion; specifically, it is 3.8 times lower than that of the existing method, even when the number of nodes in a network increases.

A numerical method of magnetic field calculation for the air-core solenoid is presented in this paper. In application of the Biot-Savart law, the magnetic field induced from the source current can be obtained by a double integration ormula. The numerical method named composite Simpson's rule for the integration is applied to the program and the adaptive quadrature method is used to adjust the step size in the calculation according to the precision we need. When the target point is in the solenoid and the intergrand's denominator may be zeroin the process of calculation, the method sill can provide an appropriate result. We have developed a program which calculates the magnetic field with at least 1ppm precision and named it as rzBI() to implement this method. The method has been used in the design of an MRI magnet, and the result show it is very flexible and convenient.
