The applicability of Diabetes Mellitus(DM) in Oriental Medicine might be placed under the category in Wasting-thirst(消渴, WT). However, because of WT having so various concepts, classification, and names in Oriental Medicine, this resulted in confusion in applying WT treatment to DM. WT occurs mainly due to dryness-heat(燥熱) which by depleting 'Fluid and Humor'(津液) makes symptoms of thirst(口渴) swift digestion with rapid hungering(消穀善饑) frequent urination(小便頻數) according to the "Internal Classic"(內經). WT was also called Sodan(消癉), Bidan(脾癉), or Sojoong(消中) in the "Internal Classic", which was caused by not only the disorder of 'five viscera' (五臟), but also the failure of 'three yin and three yang'(三陰三陽). However, the doctors of those days had a tendency to manage WT (including DM) with herbal drugs of dryness-heat or with drugs that recover the pancreas and the kidney, that have a tendency to appreciate that WT is the disease of 'five viscera'(五臟). Accoding to the "Internal Classic"(內經) and "Jinguiyaolue"(金匱要略), WT was appreciated that WT is also due to the disorder of Meridian including 'three yin and three yang'(三陰三陽) theory. Disorder of 'yang brightness'(陽明) or 'reverting yin'(厥陰) would cause Wasting-thirst(消渴), so the 'three yin and three yang'(三陰三陽) theory should be considered in WT treatments. Furthermore, 'yang brightness'(陽明) and 'reverting yin'(厥陰) all belong to 'the door'(闔) in the bolt-door-pivot(關闔樞) theory, and the mean of 'the door'(闔) is the function of storage, so we could understood WT is the wasting disease due to the disorder of 'the door'(闔) system in Meridian. WT should also be understood by the point of the bolt-door-pivot(關闔樞) theory in addition to the 'three yin and three yang'(三陰三陽) theory.

The automotive door has a large finite element model in analysis and many design requirements such as stiffness, natural frequency, side intrusion, etc. Thus, various related governing equations should be solved for systematic analysis and design. Because each governing equation has different characteristics, it is almost impossible to solve them simultaneously. Instead, they are separately handled and the analysis results are incorporated into the design separately. Currently, the design is usually conducted by trials and errors with engineering intuition in design practice. In this research, MDO methods are proposed to solve the problems that share design variables in disciplines. The idea is from the Gauss-Seidel type method for multi-discipline analysis. The developed methods show stable convergence and the weight of the door is reduced by fifteen percent.

In vehicle's door wiring harness (W/H) system is more toward to arrange a passenger compartment than a hinge and a weatherstrip. An opening/closing member of a vehicle is attached to a vehicle by a hinge in a manner enabling easy opening and closing of the opening/closing member. Such members include doors, such as side-doors and rear doors, and other opening/closing members, such as trunk lids. This article gives some insight into the dimensioning process, with special focus on large deflection analysis of wiring harness(W/H) in vehicle's door structures for durability problem. The Finite elements analysis for door wiring harness(W/H) is used for residual stresses and dimensional stability with bending flexible. Durability test data for slam test specimens were compared with the numerical predicted fatigue life for verification. The final testing of the component combines the effects of these microstructural features with the complex stress state arising from the combined service loading and residual stresses.

In this study, the safest model can be selected by the simulation result of structural safety analysis according to the shape of impact bar affected at side door of automobile. The open sectional model of semicircle type has the lowest deformation and stress among 4 kinds of models. As the weight of this model has 30% in comparison with other models, it becomes most economical and stable. As the open sectional model of cap type the highest deformation and stress among 4 kinds of models, it becomes weakest. The closed models with circular and rectangular types has the stress far lower than cap type. The maximum deformation is shown at the center part of impact bar but the maximum stress occurs at the joint part between impact bar and frame.

Weight reduction for automobile components has been sought to achieve fuel efficiency and energy conservation. There are two approaches in reducing their weights. One is by using material lighter than steel, and the other is by redesigning their structures. The latter has been performed by adopting hydroforming, tailor weled blank, optimization, etc. In this research, the kriging approximation method and simulated annealing algorithm are applied to the design of a front door made by TWB (Tailor Welded Blank) technology. The design variables are set up as the thicknesses of parts and the positions of parting lines. A thickness set considered as a design variable of each part is not arbitrarily determined but selected from standard products, so it is a discrete set. This research presents the discrete and continuous structural optimization method for an automotive door design.

First, three point bending analysis for the inclined press door impact beam was carried out to investigate inclination angle effect on the maximum strength with varying support distance. Next, for the system model with spring elements representing body stiffness at door mounting area, the bending structural behavior of impact beam mounted on vehicle was estimated. The mounting distance and inclination angle were changed and the beam bending buckling strength was presumed at the head displacement below which spring stiffness change has little effect on the load. Finally strength ratio to predict the bending buckling strength of impact beam mounted on vehicle from three point bending maximum strength of fixed support distance was suggested.
