Five phase theory has significant effect on Traditional Chinese Medicine, which puts its emphasis on correlation and integrity. However, the five phase theory itself has a limitation that it cannot reflect the general correlation and special features of affairs. Traditional Chinese Medicine pertains the five organs to five elements, absorbing the essence of the five phase theory, and transcending the limitation of the five phase theory in practice. Therefore, Traditional Chinese Medicine and other traditional medicine theories can be called as "five viscera correlation theory". On the course of modernization of traditional medicine, the effects among the five viscera can be concluded to 3 correlations of promotion, coordination and inhibition, to illustrate the integrity and correlation theory of traditional medicine from different approaches.

Objectives: This study is to analyze Acupuncture Methods(鍼法) using Five Transport Points(五輸穴) and to consider the direction of development. Methods: This study focuses on Acupuncture Methods(鍼法) using Five Transport Points(五輸穴) that Five Phase Theory(五行學說) has been applied as a compound and it is designated Five Phase-Five Transport Points-Acupuncture Method(FPT Acupuncture Method, 五行五輸穴鍼法). Principles, Acupuncture Points(經穴), standards of diagnosis and treatment subjects of FPT Acupuncture Methods used in practices of Korean Medicine (韓醫學) were analyzed through updated literature. Next, the theoretical issues of FPT Acupuncture Methods regarding the composition of selecting exclusively on Five Transport Points(五輸穴) and targeted treatment subjects were investigated. Based upon the investigation, the future direction of development was studied. Results & Conclusions: Firstly, pattern identification and treatment of FPT Acupuncture Methods targeted mostly on Viscera and Bowels(臟腑). However, some showed the tendency to Five Phases Reductionism(五行 還元主義) which attempts to apply Five Phase Theory(五行學說) to symptoms that were not related to Viscera and Bowels(臟腑). Secondly, Five Transport Points(五輸穴) are theoretically related to 'Viscera and Bowels in Concept of Visceral Manifestation(臟象臟腑)'. Thirdly, when the cause of the symptoms exceeds the main therapeutic range of FPT Acupuncture Methods, it is effective to add Acupuncture Points(經穴) excluding Five Transport Points(五輸穴). And also, it is efficient to use Acupuncture Methods(鍼法) that is not based on principles of Five Phase Theory(五行學說). For the accomplishment, further researches on the approaches to apply basic Korean Medical principles such as Three Yin and Three Yang(三陰三陽) into Acupuncture Methods(鍼法) and Acupuncture Points(經穴) are necessary.

Traditional Chinese Medicine is based on Five Phase theory that link Liver, Heart, Spleen, Lung, Kidney to Wood, Fire, Earth, Metal, Water respectively. Recently, some argue that this correspondence scheme had been established by political or socio-humane issues in early Eastern Han dynasty. But according to our analysis on Changgongyeoljeon(in Sagi), it has been revealed that this scheme had their own history from early Western Han dynasty. So we may conclude that people with medical profession had preserved the current correspondence scheme in Five Phase theory regardless trends of literature and politics in Western and Eastern Han dynasty.

The visceral manifestation theory in the "Hwangjenaegyeong(黃帝內經)" was constructed by the reference of the study of Confucian classics which main characteristics is the extensive application of the five phase theory. "Image" plays an important role in the thinking of the Chinese ancient people and it is the basis of the construction of the visceral manifestation theory. "Concept of holism" is the main directed thinking of the "Hwangjenaegyeong(黃帝內經)" "Four seasons, five viscera, Yin yang" theory is the core contents of the visceral manifestation theory in the "Hwangjenaegyeong(黃帝內經)".

Background : Saam acupuncture were composed by applying the elemental concepts from the Five Phase theory - the relationships between the cycles such as Saeng(Sheng, 'nourishing' or 'creating') and Geuk(Ke, 'suppressing' or 'controlling') - onto the Five Phase points and 12 channels to compensate for the imbalance in each of the 12 main energy traits. Objective : The present study is aimed to find out the characteristics of Five Phase points pattern in Saam acupuncture. Methods : We analysed the characteristics of five elements of the Five Phase points in Korean medical texts such as Saamdoinchimguyogyeol, Dongeuibogam and Chimgugyeongheombang in mid Chosun Dynasty. Using non-negative factorization(NNMF) methods, we extracted the feature matrix of five elements of Five Phase points in each classic medical text. Results : In Saam acupuncture, two characteristics were most prominent: (1) "Self" component of Five elements, (2) "Mother" and "Grandmother" component of Five elements. Conclusions : Saam acupuncture used the combination of Five-Shu acupoint based on ZangFu pattern identification. Our findings suggest that grasping the characteristics of Five Phase points combinations can improve the understanding the selection of the relevant acupoints based on the ZangFu pattern identifications.

Traditionally, food and medicines are considered as having common roots. That is, their energies share the same source (藥食同源), which has created a unique food culture, and nurtured a unique academic area of dietary medicine (藥膳食料學). This study aimed to develop a desirable dietary life-style based on the oriental dietary medicine theorem originated from the schema of four qi as well as five flavors of foods (四氣五味), originated from the yin-yang and five phase theory based on a clear understanding of a modern point of view, and experimental analysis of nutrients and dietary effects of clear heat effect materials. This study can promote more healthy life-styles and prevent adult diseases by following oriental dietary medicine theory. We should develop a Yack-sun theory and dietary culture that is suitable for physical and genetic health.

To enhance torque density by harmonic current injection, optimal slot/pole combinations for five-phase permanent magnet synchronous motors (PMSM) with fractional-slot concentrated windings (FSCW) are chosen. The synchronous and the third harmonic winding factors are calculated for a series of slot/pole combinations. Two five-phase PMSM, with general FSCW (GFSCW) and modular stator FSCW (MFSCW), are analyzed and compared in detail, including the stator structures, star of slots diagrams, and MMF harmonic analysis based on the winding function theory. The analytical results are verified by finite element method, the torque characteristics and phase back-EMF are also taken into considerations. Results show that the MFSCW PMSM can produce higher average torque, while characterized by more MMF harmonic contents and larger ripple torque.

Using theoretical analysis based on Landau theory, it is shown that only five phenomenological parameters are necessary to describe the twelve bulk elastic constants of a biaxial nematic phase. Further, a simple method for determining the values of these five parameters experimentally is given. Comparison with the values of the well-known splay, twist, and bend elastic constants of the uniaial nematic is made.

The voltage-source inverters (VSI) supplying a motor drive are prone to open transistor faults. To address this issue in fault-tolerant drives applicable to electric vehicles, a new open transistor fault diagnosis (FD) method is presented in this paper. According to the proposed method, in order to define the FD index, the phase angle of the converter output current is estimated by a simple trigonometric function. The proposed FD method is adaptable, simple, capable of detecting multiple open switch faults and robust to load operational variations. Keeping the FD in mind as a mandatory part of the fault tolerant control algorithm, the FD block is applied to a five-phase converter supplying a multiphase fault-tolerant PM motor drive with non-sinusoidal unbalanced current waveforms. To investigate the performance of the FD technique, the fault-tolerant sliding mode control (SMC) of a five-phase brushless direct current (BLDC) motor is developed in this paper with the embedded FD block. Once the theory is explained, experimental waveforms are obtained from a five-phase BLDC motor to show the effectiveness of the proposed FD method. The FD algorithm is implemented on a field programmable gate array (FPGA).

The equilibrium constants of five deoxyribonucleosides (dDyd, dUrd, dGuo, dThd, dAdo) were estimated by the plate theory and the moment method under isocratic conditions of the Reversed-Phase High Performance Liquid Chromatography (RP-HPLC). The mobile phase in this system was composed of water and organic modifiers(acetonitrile and methanol) The plate theory of linear adsorption isotherm was treated on the basis of continuous flow of eluent through the plates of the column. The moment method was utilized to find the equilibrium constant from the first absolute moment of experimental data. The equilibrium constants of five deoxyribonucleosides in the two methods were very close, and also the equilibrium constants calculated by capacity factor were similar to those by both the plate theory and the moment method. The equilibrium constant was expressed as a semi-log function of the quantity of organic modifier. Excellent agreements between the calculated elusion profile by the plate theory and the experimental data were observed.
