Because of the environmental problems, automotive companies are trying to reduce the weight of car body. Therefore, TRIP(TRansformation Induced Plasticity) steels, which have high strength and ductility have been developed. Welding process is a complex process; therefore deciding the optimal welding conditions on the basis of experimental data is an effective method. However, trial-and-error method to decide the optimal conditions requires too many experiments. To overcome these problems, response surface methodology was used. Response surface methodology is a collection of mathematical and statistical techniques that are used in the modeling and analysis of problems in which a response of interest is influenced by several variables and the objective is to optimize this response. This method was applied to the resistance spot welding process of the TRIP steel to optimize the welding parameters.

Frank O. Gehry is hewn to be an architect whose design 1anguage is so arbitrary and so unexpectedly changing that it seems to be almost impossible to trace any common language or my coherence over his entire career and works. To provide a counter-argument to this conception, this study explores the transformation pattern of the design language commanded by Gehry through his works. To pursue this study, Gehry's career was divided into four periods according to the design characteristics, and thorough analysis was conducted on the transformation pattern of the language both synchronically and diachronically. Based on the analysis, it was found that Gehry had been always trying to metaphorically embody the synchronic context of any given Period into his works, and the vehicles of this embodiment were materiality and morphology. Finally the argument of this study is that the changing process of Gehry's design language is not any "revolutionary change," as it was known to be, but 〃evolutionary transformation. "on."

Objective : This article is based on a formula taken from Essential Prescriptions of the Golden Chamber(金匮要略). Shen Qi Pill(肾气丸) is generally used for such deficiency cases as: consumptive diseases, xiaoke(消渴) (waisting, thirst), beriberi, urinary problems during pregnancy, phlegm and so forth, and its main purpose is to treat Kidney Qi depletion, Qi transformation disorders, without obvious hot/cold appearance patterns. Method : Mainly through the literature study of related treatise on IInner Canon of the Yellow Emperor's internal classic(黃帝内经) and The Essential Prescriptions of the Golden Chamber. Result : According to the Yellow Emperor's internal classic, the Kidney has three main functions, storing essence, controlling the waters and holding Qi. Shen Qi Pill's(肾气丸) source formula is intended to supplement even though its constituent herbs aren't the warming type. To reinforce the Qi's transformation ability is considered to be a main function of the kidney organ, and in clinic, diagnosed kidney related problems and its treatment process are mainly associated with warming to help the Qi transforming. Conclusion : Thus recovering the kidneys Qi's transformation function is part of the process to eliminate diseases. Just cause the Kidney is deficient we shouldn't think immediately of using warming supplement herbs.

The document transformation system is more widely used in order to transform business documents efficiently in diverse organization. In established researches on document transformation systems have been carried mainly focused on XML however, it is not only transformed XML form but also EDI or local form in realistic import and export process. Particularly, in the most completed research relate on document transformation, they used ontology to get rid of non-efficiency in the connection of XML schema by manual. Hence, those researches are lack of features, which are construct and modify the domain ontology automatically and the size wasn't enough to realize itself. In this paper we study development of ontology and basic system, which is critical in intelligent document conversion system. And we develop an ontology with editor can be modified and complemented by users, as well as we make it used in real import and export business process.

The phase transformation, variation of secondary phase, and critical current density $(J_c) for (Bi,Pb)_2Sr_2Ca_2Cu_3O_10 (2223)$ tapes have been studied through the thermal slide heat treatment (TSHT) process. This process consists of a multiple variations of oxygen partial pressures and temperatures at the initial heat treatment During the initial heat treatment some secondary phase such as $(Ca,Sr)_2CuO_3(2/1 AEC), (Ca,Sr)_{14}Cu_{24}O_{41} (14/24 AEC), and (Bi,Pb)_2Sr_2CuO_y$(2201, amorphous phase) farm in Bi-2223 tapes, especially at the 2223 grain boundaries. These secondary phases are detrimental to the phase transformation and final properties. In order to control the secondary phase in Bi-2223 tapes the amount and size of secondary phases among the TSHT process were observed. The results indicate that the amount and particle size of AEC particles were smaller when the TSHT process was used than when the normal process at the initial heat treatment was used which results in the improved $J_c$ properties after the final process.

In todays security industry, personal identification is also based on biometric. Biometric identification is performed basing on the measurement and comparison of physiological and behavioral characteristics, Biometric for recognition includes voice dynamics, signature dynamics, hand geometry, fingerprint, iris, etc. Iris can serve as a kind of living passport or living password. Iris recognition system is the one of the most reliable biometrics recognition system. This is applied to client/server system such as the electronic commerce and electronic banking from stand-alone system or networks, ATMs, etc. A new algorithm using nonlinear function in recognition process is proposed in this paper. An algorithm is proposed to determine the localized iris from the iris image received from iris input camera in client. For the first step, the algorithm determines the center of pupil. For the second step, the algorithm determines the outer boundary of the iris and the pupillary boundary. The localized iris area is transform into polar coordinates. After performing three times Wavelet transformation, normalization was done using sigmoid function. The converting binary process performs normalized value of pixel from 0 to 255 to be binary value, and then the converting binary process is compare pairs of two adjacent pixels. The binary code of the iris is transmitted to the by server. the network. In the server, the comparing process compares the binary value of presented iris to the reference value in the University database. Process of recognition or rejection is dependent on the value of Hamming Distance. After matching the binary value of presented iris with the database stored in the server, the result is transmitted to the client.

In order to establish a reliable and highly efficient method for genetic transformation of pepper, a monitoring system featuring GFP (green fluorescent protein) as a report marker was applied to Agrobacteriummediated transformation. A callus-induced transformation (CIT) system was used to transform the GFP gene. GFP expression was observed in all tissues of $T_0$, $T_1$ and $T_2$ peppers, constituting the first instance in which the whole pepper plant has exhibited GFP fluorescence. A total of 38 T0 peppers were obtained from 4,200 explants. The transformation rate ranged from 0.47 to 1.83% depending on the genotype, which was higher than that obtained by CIT without the GFP monitoring system. This technique could enhance selection power by monitoring GFP expression at the early stage of callus in vitro. The detection of GFP expression in the callus led to successful identification of the shoot that contained the transgene. Thus, this technique saved lots of time and money for conducting the genetic transformation process of pepper. In addition, a co-transformation technique was applied to the target transgene, CaCS (encoding capsaicinoid synthetase of Capsicum) along with GFP. Paprika varieties were transformed by the CaCS::GFP construct, and GFP expression in callus tissues of paprika was monitored to select the right transformant.

Objective : Min fire(民火) is mentioned as a kind of fire that exists in human body, which rarely appears in traditional medical books. It was mainly mentioned as a fire in urinary bladder, and was referred to have some function in the process of qi transformation(氣化) in urinary bladder. As the concept of min fire was originated from the Taoist internal alchemy, this study will make a comparative research between the examples of min fire in medical theory and Taoist internal alchemy, and will find out the conceptual significance of min fire in medical theory. Method : Among traditional medical books, min fire appears in such books as Yixuerumen(醫學入門), Youyoujicheng(幼幼集成), Fengshijinnangmilu(馮氏錦囊秘錄), and also in some books of Taoist internal alchemy. Though rather brief and informal, they show us some information about the performance of min fire in human body. So based on the information about min fire that was acquired from those books, this study will apply the concept of min fire to the traditional dispute on the problem of qi transformation in urinary bladder. Result & Conclusion : The concept of min fire that is related to the problem of qi transformation in urinary bladder, shows well that qi transformation in urinary bladder produces not only urine but also the ascent of shuijing(水精). And it also shows well that min fire acts as a power for the qi transformation in urinary bladder, which would perform well in the cooperation with sovereign fire(君火). This can be presented as a theoretical basis that the power for the qi transformation in urinary bladder is basically prepared in urinary bladder itself.

As digital contents based on 3D graphics are increased, the requirement for low power 3D graphic hardware for mobile devices is increased. We design a transformation engine for mobile 3D graphic processor. We propose a simplified transformation engine for mobile 3D graphic processor. The area of the transformation engine is reduced by merging a mapping transformation unit into a projective transformation unit and by replacing a clipping unit with a selection unit. It consists of a viewing transformation unit a projective transformation unit a divide by w nit, and a selection unit. It can process 32 bit floating point format of the IEEE-754 standard or a reduced 24 bit floating point format. It has a pipelined architecture so that a vertex is processed every 4 cycles except for the initial latency. The RTL code is verified using an FPGA.
