In order to confirm the efficiency of Oriental medical treatment on Vascular dementia, 24 probable and possible vascular dementia patients diagnosed by ADDTC criteria, were chosen and followed among the patients who had visited KOMC from April, 1996 to March, 1997. They were given herbal and acupuncture therapy, mainly focused on circulating qi(順氣)and removing phlegm(治痰) which is generally applied in early stage of cerebro-vascular disease, and then assessed by the improvement of stage according to the level of impairment, as proposed by APA. The results were as followed. 1. Out of 25 cases, 8 patients showed 2 grade improvement(++), 15 patients showed 1 grade improvement(+), and 1 patient showed no change. 2. The efficiency of treatment is higher when they're given treatment earlier. 3. The efficiency of treatment is higher when their symptoms are lighter. In conclusion, this study shows meaningful effect of Oriental medical treatment on vascular dementia and also shows that It's more effective in the case of short onset and mild symptom.

Two major endoglucanase genes (cel7B and cel5A) were cloned from Penicillium decumbens 114-2 using the method of modified thermal asymmetric interlaced polymerase chain reaction (TAIL-PCR). The result of Southern blotting suggested that P. decumbens has a single copy of the cel5A gene and a single copy of the cel7B gene in its chromosomal DNA. The expression levels of cel5A and cel7B were determined by means of real-time quantitative PCR, suggesting that the two genes were coordinately expressed, and repressed by glucose and induced by cellulose. Both endoglucanase genes were expressed in Saccharomyces cerevisiae and the recombinant proteins were purified. The recombinant Cel7B and Cel5A were both optimally active at $60^{\circ}C$ and pH 4.0. The recombinant Cel7B showed more than 8-fold, 30-fold, and 5-fold higher enzyme activities toward carboxymethyl cellulose, barley $\beta$-glucan, and PASC, respectively, in comparison with that of Cel5A. However, their activities toward pNPC and Avicel showed minor differences. The results suggested that Cel7B is a strict endoglucanase, whereas Cel5A showed processivity because of its relative higher ability to hydrolyze the crystal cellulose.

Hyperhidrosis is common complication of spinal cord injury, but localized unilateral hyperhidrosis is relatively rare disorder without autonomic disreflexia. A 52-year-old man with a 10-month history of cervical injury induced tetraplegia complained of excessive intermittent left-sided sweating. The sweating occurred by urinary retention or without any autonomic dysreflexia. The patient sweated excessively on the left face and upper body. In the point of Differentiation of Syndrom (辨證), the patient was diagnosed as Gi-Heo-Hyeol-Eo (Pi-Wei-Qi-Xu 氣虛血瘀) and was administered revised Boyanghwano-tang (reserved Bu-Yang-Huan-Wu-tang), and he was almost complaint free during 4 month about none dysreflexial hyperhidrosis.

A new conception of public-key cryptography MEPKC, Petri net based Multi-stage-Encryption Public-Key Cryptography, has been proposed in onder to guarantee stronger network communication security. Different from an ordinary public-key cryptography that opens only a single public key to the public, MEPKC opens a key-generator that can generate multiple encryption keys and uses these keys to encrypt a plain text to a cipher text stage by stage. In this paper, we propose the methods how to carry out the encryption operations. First, we describe how to design a hash function H that is used to conceal the encryption keys from attack. Then, given with a key-generator (a Petri net supposed to possess a large number of elementary T-invariants), we discuss how to randomly generate a series of encryption keys, the elementary T-invariants. Finally, we show how to use these encryption keys to encrypt a plain text to a cipher text by applying a private key cryptography, say DES.

A workflow is a flow of work supported by computers. An instance of a workflow is called case. Companies need to constantly refine their current workflows in order to meet various requirements. The change of current workflows is called dynamic change of the workflow. Since Ellis et al. proposed three change types, Flush, Abort, and Synthetic Cut-Over in 1995, various change types have been proposed. A promising change type is Migrate proposed by Sadiq et al., because Migrate changes workflow definitions immediately and makes the redo of cases minimum. However, the formal modeling and time-dependent analysis of Migrate has not been done. This paper proposes a method of computing change time of Migrate dynamic changes for time-dependent analysis. Change time is a measure for evaluating dynamic changes. We first show a Petri-nets-based model of Migrate dynamic changes. Then we present a method of computing change time based on the net model. Finally, we apply the method to 270 examples, and show experimental results, and comparison with Ellis et al..'s three change types.

A static load analysis of twin-screw kneaders is required not only for the dynamic analysis, but also because it is the basis of the stiffness and strength calculations that are essential for the design of bearings. In this paper, the static loads of twin-screw kneaders are analyzed, and a mathematical model of the force and torque moments is presented using a numerical integration method based on differential geometry theory. The calculations of the force and torque moments of the twin-screw kneader are given. The results show that the $M_x$ and $M_y$ components of the fluid resistance torque of the rotors change periodically in each rotation cycle, but the $M_z$ component remains constant. The axis forces $F_z$ in the female and male rotors are also constant. The static load calculated by the proposed method tends to be conservative compared to traditional methods. The proposed method not only meets the static load analysis requirements for twin-screw kneaders, but can also be used as a static load analysis method for screw pumps and screw compressors.

Cetirizine hydrochloride reacted with $BiI_4^-$ in an acidic aqueous solution to form precipitate. After centrifugation, the atomic emission intensity of $Bi^{3+}$ contained in the supernatant solution was measured at the characteristic wavelength of 206.170 nm. The difference between the spectral signal intensity of the blank solution and that of the supernatant, ${\Delta}I$, was linearly related to the concentration of cetirizine hydrochloride. As a result, a new inductively coupled plasmaatomic emission spectrometric (ICP-AES) method was developed for the analysis of cetirizine hydrochloride. The linear range was from 27.7 to 184.8 $mg{\cdot}L^{-1}$, with a correlation coefficient (r) of 0.9961 and a detection limit of 9.6 $mg{\cdot}L^{-1}$. This method is simple and accurate, Without using toxic organic solvents, and is feasible for the quality control of cetirizine hydrochloride tablets and capsules.

Generally, there are many kinds of pumps used on a ship, which play an obbligato role to assist the ship's running. However, due to the pump's own motor, it becomes a main vibration resource that may cause serious problems in local. If the above situation happened, it may cause local resonance even structural damage. Also, the bigger the pump's size is, the more serious the vibration is. Therefore, it is very important for researchers to estimate the vibrations situation of pumps accurately and avoid or reduce the probability of resonance. Based on a real marine pump-HHG8065, this paper did a vibration analysis by FEM (Finite Element Method) and compared the results with actual test. Finally, it gave a discussion on the estimation of pump and provided an improvement way to the vibration level.

A novel chemiluminescence (CL) flow injection method for the determination of balofloxacin is described. The method is based on the weak CL signal arising from the reaction of $KBrO_3$ with $Na_2S_2O_4$ in acidic medium being significantly enhanced by balofloxacin in the presence of europium (III) ion and sodium dodecyl benzene sulfonate (SDBS). The experimental conditions that affected CL intensity were carefully optimized and the CL reaction mechanism was briefly discussed. Under the optimum conditions, the relative CL intensity was proportional to the concentration of balofloxacin in the range of $7.0{\times}10^{-11}$ to $3.0{\times}10^{-7}g\;mL^{-1}$. The detection limit was $2.7{\times}10^{-11}g\;mL^{-1}$ and the relative standard deviation was 2.1% for $7.0{\times}10^{-10}g\;mL^{-1}$ balofloxacin (n = 13). The proposed method was successfully applied to the determination of balofloxacin in pharmaceutical formulations and biological fluids.
