Objectives : Suwenliuqixuanzhumiyu is a book that strongly influenced the following generations' theory of five Circuits and six Qi. It is understood that Wangbing authored the book during the Tang dynasty, but another theory suggests that a nameless author devised the book falsely in Wangbing's name. A comprehensive research is greatly significant in the development of the theory of five Circuits and six Qi. Methods : The study will focus on the analysis on the truth about Suwenliuqixuanzhumiyu, its impact on the following generations' theory of five Circuits and six Qi, the contents and comparison of Suwen's xuanzhumiyu, and the 17 books and 27 chapters of xuanzhumiyu. Results & Conclusions : First, xuanzhu was authored by Wangbing sometime around 762 AD, and Suwenliuqixuanzhumiyu was written in 690 during the rule of Empress Wu Zetian, meaning that Wangbing is not the author of Suwenliuqixuanzhumiyu. Second, Wangbing's style of writing is regular yet elegant, and keeps itself within the range of medical style of writing, but Suwenliuqixuanzhumiyu is written in a very rough style, and finds itself within the range of Tao literatures and books on trickery. Third, Wangbing's xuanzhu is a commentary on Suwen, whereas Suwenliuqixuanzhumiyu is consisting of the theory of five Circuits and six Qi, and trickeries predictive picture. As such, the two books have entirely different characters. Theories that received relatively significant impacts to the following generations' the theory of five Circuits and six Qi include Gandeokbu, Jeongwhadaewha, and the Calculation method of normal Qi. Suwen's chapter on the theory of five Circuits and six Qi and Suwenliuqixuanzhumiyu have many inconsistent and differing theories, leading the scholars to believe that they are dealing with different theory of five Circuits and six Qi which derived from separate schools of beliefs.

The task of plastic theory is twofold: first, to set up relationships between stress and strain that adequately describe the observed plastic deformation of metals, and second, to develop techniques for using these relationships in studying of the mechanics of metal forming processes, and the anlaysis and design of structures. One of the major problems in the theory of plasticity is to describe the behavior of work-hardening materials in the plastic range for complex loading histories. This can be achieved by formulating constitutive laws either in the integral or differential forms. To adequately predict the response of steel members during cyclic loading, the hardening rule must account for the features of cyclic stress-strain behavior. Neithe of the basic isotropic and kinematic hardening rules is suitable for describing cyclic streess-strain behavior, although a kinematic hardening rule describes the nearly linear portions of the stabilized hystersis loops. There is also a limited expansion of the yield surface as predicted by the isotropic hardening rule. Strong ground motions or wind gusts affect the complex and nonproportional loading histories in the inelastic behavior of structues rather than the proportional loading. Nonproportional loading is defined as externally applied forces on the structure, with variable ratios during the entire loading history. This also includes the rate of time-dependency of the loads. For nonproportional loading histories, unloading may take place along a chord instead of the radius of the load surface. In such cases, the shape of the stress-strain curve has to be determined experimentally for all non-radial loading conditions. The plasticity models including two surface models ae surveyed based on a yield surface and a bound surface that represent a state of maximum stress. This paper is concerned with the improvement of a plasticity models of the two-surface type for structural steel. This is follwed by an overview of plasticity models on structural steel. Finally the need for further research is identified.

The purpose of this study is to search for the main content system and Confucian meaning of "Yu Shu;虞書" of "The Book of Documents; 書經". This research covers two things: first, the form of The Book of Documents and the main content system of "Yu Shu". The Book of Documents consists of 4 main dynasties' Shu in ancient chinese history; "Yu Shu" 5 chapters, "Xia Shu; 夏書" 4 chapters, "Shang Shu; 商書" 17 chapters, and "Zhou Shu; 周書" 32 chapters, for a total 58 chapters. This book is organized in the form of six formalities(六體) or ten examples(十例). Second, the Confucian value of The Book of Documents and philosophical meaning of Yu Shu. Yu Shu shows a benign rule(仁政), confucianism ideal politic, as an historic example of a benevolent administration. By this research, we recognize that the tradition of abdication in the confucian society and the way of selecting people are theoretical foundation of politics based on people, rule by virtue and, by extension, a dynastic revolution. In addition, governing a country and rule the world that is treated in Yu Shu are a theory of leadership and moral training as a background of "Da Xue"(大學; Great Learning). Furthermore, Xiao(孝;filial piety) emphasized on this book is the main virtue of leaders and core value of practical action among the human relation. by extension, we recognize that the "Yu Shu" is the origin of "Xiao Jing; 孝經".

Rodolphe Toepfer invented cartoon frames and following cartoonists developed this idea. But cartoon frames defineed before in historical documens and artifacts give a hint of the structure of a cartoon frame. In historical documents and artifacts show various form of the quadrangle frames. Now we see the cartoon frame is a result of historical things. Artists input in the framework, dubbed as a cartoon frame, all kinds of icons that belong to cartoon's language. Readers accept messages that artists want to say by considering this formation. Although cartoon frames are similar to camera frames they are more flexible than other general frames. By this flexibility, different shapes of frame influence reader's experiences. Applying these various cartoon frames extends function of framework. And if used by many cartoonists, you gradually get a rule. A time-tested rule standardizes it. In theory, shapes of frame are changeable in many ways. But frequently used frames are standardized in just one formation. In the process, I think it is a tacit rule of human lifestyle. That is a quadrangle. Why is the quadrangle chosen by a long term polished rule of frame? This study is to realise why a quadrangle form is used and its relation to human lifestyle.

The physiological signals measured by Oriental Medicine instruments have been analyzed quantitatively in the view of the rule of promoting and counteracting relation of five evolutive phases theory. We tried to reduce the physiological signals measured by EAV(Elec-tro-Acupuncture according to Voll) and IR thermography to the representation of five evelutive phases. The EAV index and local skin temperature on acupuncture points of each phases measured and normalized so that the total value of five phases became unity. We assumed that the normalized EAV index and local skin temperature mean the deficiency or excess of Qi for each phases. The state of Qi distribution for each phases were approximately agree with the diagnostic pattern of O. M. doctor. Taking account of the Qi distribution state of·or the five evolutive phases, we performed a proper needle insertion on acupuncture points to induce the distinct change of Qi for each phases. We compared the measured results with the predictions of Qi variation by the rule of pro- moting and counteracting relation over the five evolutive phases. For all cases, the variation of Qi in the own phase on which a needle insertion was performed were exactly same to the theoretical prediction and partial agreement was shown for the other four phases. The same analysis was carried to the results of skin temperature measurements at accupoints. We found that the local skin temperature at accupoints of each phases shelved a finite change by the needle insertion and the behavior- of its change were strongly correlated to the rule of promoting and counteracting relation of five evolutive phases.

In this paper, we introduce and investigate a new category of rule-based fuzzy inference system based on Information Granulation(IG). The proposed rule-based fuzzy modeling implements system structure and parameter identification in the efficient form of “If..., then...” statements, and exploits the theory of system optimization and fuzzy implication rules. The form of the fuzzy rules comes with three types of fuzzy inferences: a simplified one that involves conclusions that are fixed numeric values, a linear one where the conclusion part is viewed as a linear function of inputs, and a regression polynomial one as the extended type of the linear one. By the nature of the rule-based fuzzy systems, these fuzzy models are geared toward capturing relationships between information granules. The form of the information granules themselves becomes an important design features of the fuzzy model. Information granulation with the aid of HCM(Hard C-Means) clustering algorithm hell)s determine the initial parameters of rule-based fuzzy model such as the initial apexes of the membership functions and the initial values of polynomial function being used in the Premise and consequence Part of the fuzzy rules. And then the initial Parameters are tuned (adjusted) effectively with the aid of the improved complex method(ICM) and the standard least square method(LSM). In the sequel, the ICM and LSM lead to fine-tuning of the parameters of premise membership functions and consequent polynomial functions in the rules of fuzzy model. An aggregate objective function with a weighting factor is proposed in order to achieve a balance between performance of the fuzzy model. Numerical examples are included to evaluate the performance of the proposed model. They are also contrasted with the performance of the fuzzy models existing in the literature.

This study theoretically analyzes the cost allocation of replacement costs that occur when existing operators have to replace circuit breakers due to the entry of new generators. We adopt the sequential equal contributions rule as the cost allocation rule, which is widely used in cost allocation problems in cooperative game theory. We derive various cost allocation plans based on several criteria and examine to what extent each alternative meets various desirable axioms. According to the analysis, (i) the alternative that excludes the cost of the new operator, residual value, and network operator and (ii) the alternative that excludes the cost of the new operator, residual value, and includes network operator are relatively superior to other schemes. We also identify a realistic plan by taking into account practical factors and analyze its axiomatic characteristics.

Nonlinear behavior of functionally graded material (FGM) plates under thermal loads is investigated here using an efficient sinusoidal shear deformation theory. The displacement field is chosen based on assumptions that the in-plane and transverse displacements consist of bending and shear components, and the shear components of in-plane displacements give rise to the sinusoidal distribution of transverse shear stress through the thickness in such a way that shear stresses vanish on the plate surfaces. Therefore, there is no need to use shear correction factor. Unlike the conventional sinusoidal shear deformation theory, the proposed efficient sinusoidal shear deformation theory contains only four unknowns. The material is graded in the thickness direction and a simple power law based on the rule of mixture is used to estimate the effective material properties. The neutral surface position for such FGM plates is determined and the sinusoidal shear deformation theory based on exact neutral surface position is employed here. There is no stretching-bending coupling effect in the neutral surface-based formulation, and consequently, the governing equations and boundary conditions of functionally graded plates based on neutral surface have the simple forms as those of isotropic plates. The non-linear strain-displacement relations are also taken into consideration. The thermal loads are assumed as uniform, linear and non-linear temperature rises across the thickness direction. Closed-form solutions are presented to calculate the critical buckling temperature, which are useful for engineers in design. Numerical results are presented for the present efficient sinusoidal shear deformation theory, demonstrating its importance and accuracy in comparison to other theories.

In this study, it propose a proof theory method for expressing and reasoning knowledge in a multiagent environment. Since this method determines logical results in a mechanical way, it has developed as a core field from early AI research. However, since the proposition cannot always be proved in any set of closed sentences, in order for the logical result to be determinable, the range of expression is limited to the sentence in the form of a clause. In addition, the resolution principle, a simple and strong reasoning rule applicable only to clause-type sentences, is applied. Also, since the proof theory can be expressed as a meta predicate, it can be extended to the metalogic of the proof theory. Metalogic can be superior in terms of practicality and efficiency based on improved expressive power over epistemic logic of model theory. To prove this, the semantic method of epistemic logic and the metalogic method of proof theory are applied to the Muddy Children problem, respectively. As a result, it prove that the method of expressing and reasoning knowledge and common knowledge using metalogic in a cooperative multiagent environment is more efficient.

A new method, the Triple I method is proposed for solving the problem of fuzzy reasoning. The Triple I method for solving fuzzy modus ponens is compared with the CRI method i.e., Compositional Rule of Inference and reasonableness of the Triple I method is clarified. Moreover the Triple I method can be generalized to provide a theory of sustentation degrees. Lastly, the Triple I method can be bring into the framework of classic logics.
