The following results were reached through investigations on the prescriptions using Rhei Rhizoma as a main component. Objectives : Analysis of prescriptions According to the formula : Liquid Extract Prescriptions were used widely on three parts to treat fever and damp heat in the interior organs. Powder Prescriptions were taken with hot water, thin porridge, tea etc. to treat damp heat, congestion of phlegm, acute episodes. Liquid Mixed Pill treat congestion of QI, damp heat, phlegm. Honey Mixed Pill treat accumulated fever, distension, acute excessive fever. Paste Pill treat blood stagnation, excessive toxic-fever, epidemic diseases. External Application treat inflammation by injury, swelling due to severe fever by internal damage. Methods : Analysis of prescriptions According to the manipulation of Rhei Rhizoma : Prescriptions including Liquor processed Rhei Rhizoma treat excessive toxic-fever, congestion of phlegm, blocking orifices on the upper side. Steamed Rhei Rhizoma strengthen effects of making evacuate and cooling of heat. Processed Rhei Rhizoma with vinegar strengthen effects of removing blood stagnation by activating blood movement, releasing gathering. Results : Analysis of prescriptions According to the Composition of Rhei Rhizoma : 41% of the total prescriptions were on the area of less than 20%. In case of lower groups show increased frequency of combination with Pharbitidis Semen, Persicae Semen, Scutellariae Radix and manipulation of baking, steaming, roasting. In case of higher groups show increased frequency of treating excess syndrome, critical illness, acute severe illness, and using proccesed Rhei Rhizoma with vinegar. Treatment of damp heat on the liver and gallbladder, disorder of the spleen and stomach is done mostly by prescriptions on the area of less than 30%.

Residue Number System is used for the purpose of increasing the speed of processing in the many application parts of Image Processing, Computer Graphic, Neural Computing, Digital Signal Processing etc, since it has the characteristic of parallelism and no carry propagation at each moduli. DRNS has the twice RNS Conversion, it is used to decreases the size of the operator in RNS. But it has a week point on the Second Residue to First Residue Conversion time. So, in this paper SRTFR(Second Residue to First Residue) Converter using MRC(Mixed Radix Conversion) is designed to decrease the size of RTB(Residue to Binary) Converter. Since the proposed SRTFR Converter using MRC(Mixed Rdix Convertion) has a pipeline processing. Also, modular operation is applied to at each partitioned SAM(Subtraction and Addition) and MA(Multiplication and addition). In the following study, the more effective design on MA is needed.

Objectives : Huangqintang(⿈芩湯) is a famous herbal prescription in the Traditional Korean Medicine (e.g. Shanghanlun) to treat various chronic disease such as neurological disease and digestive system disease. Its components include Scutellariae Radix(⿈芩), Paeonia lactiflora(芍藥), Glycyrrhizae Radix et Rhizoma(⽢草), Zizyphi Fructus(⼤棗). Methods : In this study, we standardize the name, composition and medical uses of Huangqintang by literature studying and paper searching. Based on the comparison between oriental medicine and modern medicine pharmacology, we linked the medical uses of Huangqintang to Korean Standard Classification of Diseases (KCD). Results and Conclusion : The name of the prescription is unified into "Huangqintang", and its composition ratio between Scutellariae Radix, Paeonia lactiflora, Glycyrrhizae Radix et Rhizoma, and Zizyphi Fructus is 3:2:2:3. Huangqintang is used for enteritis diseases due to its antipyretic and antinflammatory effects. Its medical application was relatied with 'A'code, 'C'code, and 'K'code as indicated by KCD. By standardizing the mixed conceptions of Huangqintang, this review will facilitate the coding of Huangqintang prescription. Therefore, it will make Huangqintang prescription more useful in clinics.

The Extension of Base is a fundamental Method to expend the moduli in RNS(Residue Number System). RNS has the benefit of parallelism and no carry propagation at each moduli, but division , extension of base and etc. is the problem of RNS in case of the operation speed.Generally this method is applied to system using Mixed Radix Conversion. it appears to decrease the size of Arithmetic Unit, but increasing the time of operation. So in this paper, the Improved Extension of Base is proposed using Chinese Remainder Theorem. it has the comparative small size and Improved speed.

We propose and describe new error control algorithms for redundant residue number systems (RRNSs) and residue number system product codes. These algorithms employ search techniques for obtaining error values from within a set of values (that contains all possible error values). For a given RRNS, the error control algorithms have a computational complexity of $t{\cdot}O(log_2\;n+log_2\;{\bar{m}})$ comparison operations, where t denotes the error correcting capability, n denotes the number of moduli, and ${\bar{m}}$ denotes the geometric average of moduli. These algorithms avoid most modular operations. We describe a refinement to the proposed algorithms that further avoids the modular operation required in their respective first steps, with an increase of ${\lceil}log_2\;n{\rceil}$ to their computational complexity. The new algorithms provide significant computational advantages over existing methods.

MRNS network is a general algebraic structure of Hypercube network which has recently drawn considerable attention to supercomputing and message-passing communication. In this paper, we investigate the routing of a message in an n- dimensional MRNS network that is a key to the performance of this network. On the n-dimensional MRNS network we would like to transmit packets from a source node to a destination node simultaneously along a fixed number of paths, where the superscript packet will traverse along the superscript path. In order for all packets to arrive at the destination node quickly and securely, the ith path must be node-disjoint from all other paths. By investigating the conditions of node-disjoint paths, we will employ the special matrices called as the Hamiltonian Circuit Latin Square(HCLS) described in 〔1〕to construct a set of node-disjoint paths and suggest a linear-time parallel routing algorithm for the MRNS network.

Scaling is an important operation because of the iterative nature of arithmetic processes in digital signal processors (DSPs). In residue number system (RNS)-based DSPs, scaling represents a performance bottleneck based on the complexity of intermodulo operations. To design an efficient RNS scaler for special moduli sets, a body of literature has been dedicated to the study of the well-known moduli sets {2ⁿ - 1, 2ⁿ, 2ⁿ + 1} and {2ⁿ, 2ⁿ - 1, 2ⁿ⁺¹ - 1}, and their extension in vertical or horizontal forms. In this study, we propose an efficient programmable RNS scaler for the arithmetic-friendly moduli set {2^n+p, 2ⁿ - 1, 2ⁿ⁺¹ - 1}. The proposed algorithm yields high speed and energy-efficient realization of an RNS programmable scaler based on the effective exploitation of the mixed-radix representation, parallelism, and a hardware sharing technique. Experimental results obtained for a 130 nm CMOS ASIC technology demonstrate the superiority of the proposed programmable scaler compared to the only available and highly effective hybrid programmable scaler for an identical moduli set. The proposed scaler provides 43.28% less power consumption, 33.27% faster execution, and 28.55% more area saving on average compared to the hybrid programmable scaler.

Routing security is related to the confidentiality of the route taken by the data transmitted over the network. If the route is detected by the adversary, the probability is higher that the data are lost or the data can be intercepted by the adversary. Therefore, the route must be protected. To accomplish this, we select an intermediate node secretly and transmit the data using this intermediate node, instead of sending the data to the destination node using the shortest path. Furthermore, if we use a number of secret routes from the starting node to the destination node, data security is much stronger since we can transmit partial data rather than the entire data along a secret route. In this paper, the routing algorithm for multiple secret paths on MRNS(Mixed Radix Number System) Network, which requires O(1) for the time complexity where is the number of links on a node, is presented employing the HCLS(Hamiltonian Circuit Latin Square) and is analyzed in terms of entropy.
