Objectives : The treatment of Bell's palsy must be divided into three states(acute, subacute and healing state). 41 cases of the patient suffering from Bell's palsy were treated and observed from january 2000 to July 2001. The usage of herbal acupunctures on that disease have been effective. So I propose a method of herbal acupunctures on Bell's palsy. Methods : By the states(acute, subacute and healing state) of Bell's palsy, SY(消炎) herbal acupuncture is used at the acute state, Hominis Placenta(紫河車) at the subacute, JGH(中氣下陷) at the healing state. Results : 1. At the acute state, SY(消炎) herbal acupuncture is effective to postauricular pain. 2. At the subacute state, Hominis Placenta(紫河車) herbal acupuncture is effective to decreasing pain and improving symptoms. 3. By the states(acute, subacute and healing state) of Bell's palsy, SY(消炎), Hominis Placenta(紫河車) and JGH(中氣下陷) herbal acupuncture is effective to improving symptoms of Bell's palsy.

The current trend in automotive finishing industry is to use more electrostatic rotating bell (ESRB) need space to their higher transfer efficiency. The flow physics related with the transfer efficiency is strongly influenced by operating parameters. In order to improve their high transfer efficiency without compromising the coating quality, a better understanding is necessary to the ESRB application of metallic basecoat painting for the automobile exterior. This paper presents the results from experimental investigation of the ESRB spray to apply water-borne painting. The visualization, the droplet size, and velocity measurements of the spray flow were conducted under the operating conditions such as liquid flow rate, shaping airflow rate, bell rotational speed, and electrostatic voltage setting. The optical techniques used in here were a microscopic and light sheet visualization by a copper vapor laser, and a phase Doppler particle analyzer (PDPA) system. Water was used as paint surrogate for simplicity. The results show that the bell rotating speed is the most important influencing parameter for atomization processes. Liquid flow rate and shaping airflow rate significantly influence the spray structure. Based on the microscopic visualization, the atomization process occurs in ligament breakup mode, which is one of three atomization modes in rotating atomizer. In the spray transport zone, droplets tend to distribute according to size with the larger drops on the outer periphery of spray. In addition, the results of present study provide detailed information on the paint spray structure and transfer processes.

The Background and Purpose : Most diagnostic method for the facial palsy were invasive and complex. And we don't know very well prognosis for the recovery of facial palsy in the first stage after the onset. But the Digital Infrared Thermal Image(DITI) isn't invasive and complex diagnostic method for the facial palsy. So we should study on the clinical prognostic diagnosis of Bell's palsy among facial palsy with the DITI. Objective and Methods : This study researched into the clinical statistics for 89 case who are in Bell's palsy, and they are treated with oriental medical care at the Woosuk university during 2 years form November 1998 to October 2000. All objectives have the Grade 6(Zero state) of Bell's palsy in first week after the onset. It takes a patient's facial temperature after the onset. Group A is taken from 1 day to 4 days after the onset. Group B is taken from 5 day to 8 days after the onset. And group C is taken from 9 day to 12 days after the onset. Results and Conclusions : The Digital Infrared thermal image technique showed the more high temperature, the more rapid cure and short treatment period on TE23, B2, S3, S6 in abnormal site of Bell's palsy. But it showed the more low temperature, the more rapid cure and short treatment period on TE17 of abnormal site of Bell's palsy. As a conclusion, we could think that the prognostic diagnosis of Bell's palsy closely related with the thermal difference normal and abnormal site of Bell's palsy that were took picture after the onset.

The pH dependence of the kinetic parameters of recombinant acetohydroxy acid synthase catalyzed reaction was determined in order to obtain information about the chemical mechanism, particularly acid-base chemistry. The maximum velocity and V/K for pyruvate were bell-shaped with estimated pK values of 6.5-6.7 and 8.6-8.9, respectively. The maximum velocity and V/K for 2-ketobutyrate were also bell-shaped with estimated pK values of 6.6-7.0 and 8.4-8.6. The pH dependence of 1/Ki for 3-bromopyruvate, a competitive inhibitor of pyruvate, was also bell-shaped, giving pK values almost identical with those obtained for pyruvate. Since the same pK values were observed in the $pK_{i 3-bromopyruvate}$, V/K pH profiles and $V_{max}$ profiles, both enzyme groups must be in their optimum protonation state for efficient binding of reactants. These results reflect that two enzyme groups are necessary for binding of substrate and/or catalysis.

This parer describes the tracking control simulation of 6-DOF shaking table with a bell crank structure, which converts the direction of reciprocating movements. For the Joint coordinate-based control which uses lengths of each actuator, the trajectory conversion process inverse kinematics is performed. Applying the Newton-Euler approach, the dynamic equation of the shaking table is derived. To cope with nonlinear problems, time-delay control(TDC) is considered, which has been noted for its exceptional robustness to parameter uncertainties and disturbance, in addition to steady-state accuracy and computational efficiency. If the nominal model is equal to the real system, joint coordinate-based control can be very efficient. However, manufacturing tolerances installation errors and link offsets contaminate the nominal values of the kinematic parameters used in the kinematic model of the shaking table. To compensate differences between the nominal model and the real system. the joint coordinate-based control using acceleration feedback in the Cartesian coordinate space is proposed.

Let p be a prime number. It is known that the order o(r) of a root r of the irreducible polynomial $x^p-x-l$ over $\mathbb{F}_p$ divides $g(p)=\frac{p^p-1}{p-1}$. Samuel Wagstaff recently conjectured that o(r) = g(p) for any prime p. The main object of the paper is to give some subsets S of {1,...,g(p)} that do not contain o(r).

Kinetic studies on the reactions of five secondary acylic alkyl arenesulfonates with anilines are carried out in acetonitrile at 65.0 ℃. The magnitude of ρXZ determined (ρXZ=0.12-0.13) is slightly greater than that for the alicyclic series (ρXZ=0.11) under the same experimental condition. Ab initio MO results are found to support the slightly tighter transition state expected from the greater magnitude of ρXZ for the acyclic series. Despite the small variations, the magnitude of ρXZ and the theoretical transition state tightness remain relatively constant for the secondary carbon centers. Secondary kinetic isotope effects involving deuterated aniline nucleophiles show a successively smaller kH/kD(<1.0) value for a more sterically crowded reaction center carbon. This is in accord with the later transition state for bond-making predicted by the Bell-Evans-Polanyi principle for the more endothermic nucleophilic substitution reaction. Further support is provided by the results of the AM1 MO calculations on the reactions of secondary alkyl benzenesulfonates with chloride nucleophile.

Magnetron sputtered TiN, (Ti, Al)N and TiN/(Ti, Al)N multilayer coatings grown on cemented carbide substrates have been characterized by using electron probe microanalysis (EPMA), X-ray diffraction (XRD), scanning electron spectroscopy (SEM), nanoindentation, scratcher and cutting tests. Results show that TiN coating is bell mouth columnar structures, (Ti, Al)N coating is straight columnar structures and the modulation structure has been formed in the TiN/(Ti, Al)N multilayer coating. TiN/(Ti, Al)N multilayer coating exhibited higher hardness, better adhesion with substrate and excellent cutting performance compared with TiN and (Ti, Al)N coating.

High pressure X-ray diffraction study was carried out on a natural FeO(OH)-goethite to investigate its compressibility at room temperature. Energy dispersive X-ray diffraction method was employed using Mao-Bell type diamond anvil cell with Synchrotron Radiation. MgO powder was compressed together with goethite for the high pressure determinations. Bulk modullus was determined to be 147.9 GPa by the Birch-Murnaghan equation of state under assumption of K0' of 4. This value was subjected to compare with its structural analogs and related materials.
