Cynanchi Wilfordii Radix has been used for the treatment of prematurely grey hair, bald and constipation and Polygoni Multiflori Radix has been used for the treatment of weakness, knee pain, premature greying, elevated serum cholesterol, coronary heart disease, naurasthenia and insominia. Pattern recognition for the analysis of Cynanchi Wilfordii Radix and Polygoni Multiflori Radix was conducted using HPLC method. Pattern of Cynanchi Wilfordii Radix and Polygoni Multiflori Radix was different and we distinguished two medicinal plants by HPLC.

Vibration table is required to obtain high packing density in lost form casting process. Packing density, which is important manufacture factor, depends on the vibration pattern induced by vibration table. In general, circular vibration pattern is recognized as the best pattern. The existing vibration table is investigated to identify current vibration pattern and consider a countermeasure. Modal test is utilized to identify the dynamic characteristics of vibration table, and finite element method is used to present the improved design

For a good design, it is important to understand consumers and trend of textile and fashion design. Previous researches on textile pattern design with CAD have been done. They have studied on Korean traditional floral motives/hand painting or some geometric patterns. Few studies have been done on conversational design. Therefore the purpose of study was to observe types of textile pattern design for the recent fiver years and determine fabric pattern trends, especially on the conversational motifs. The types of patterns were analysed with professional panels from the 2005～2009 collection sources, using SPSS program. This study was also develop textile patterns creating using CAD. We conducted design process on motif creating, repeat, and mapping jobs, using textile special design program Prima vision and Photoshop CS3.

Rapid Prototyping(RP) has been widely applied in designing and developing process of new products. RP can reduce the lead time and expense required to bring a new product form initial concept to production. Among several RP process can dramatically reduce the total build time and be applied for fabrication of large-sized and free form object because it uses in LOM the paper thickness is 0.05∼0.38mm as deposition feature segment. In this study, mechanical properties of pattern with LOM system is studied for optimal design of sand mold casting. The main result is that tensile, compressive strength and pattern size are significantly affected by temperature of hot roll.

Calculation of the launch-condition dependent near field pattern, modal power distribution and far field pattern of the SGS mode scrambler by ray optical approch fits well with the experiment. These results were applied to explain how to establish the stable mode launching into the grated index multimode fiber under test by the SGS mode scrambler. The effective use of the 5G5 mode scrambler is found to restrict the launching NA as well as possible. This was also confirmed by experiment.

Recently, It is gradually raised necessity that thickness of thin film is measured accuracy and managed in industrial circles and medical world. Ultrasonic Signal processing method is likely to become a very powerful method for NDE method of detection of microdefects and thickness measurement of thin film below the limit of Ultrasonic distance resolution in the opaque materials, provides useful information that cannot be obtained by a conventional measuring system. In the present research, considering a thin film below the limit of ultrasonic distance resolution sandwiched between three substances as acoustical analysis model, demonstrated the usefulness of ultrasonic Signal processing technique using information of ultrasonic frequency for NDE of measurements of thin film thickness, sound velocity, and step height, regardless of interference phenomenon. Numeral information was deduced and quantified effective information from the image. Also, pattern recognition of a defected input image was performed by neural network algorithm. Input pattern of various numeral was composed combinationally, and then, it was studied by neural network. Furthermore, possibility of pattern recognition was confirmed on artifical defected input data formed by simulation. Finally, application on unknown input pattern was also examined.

Objective : The objective of this study is to define the conceptional meaning of Shanghanlun provision while applying Shanghanlun disease pattern identification diagnostic system. Methods : 2 clinical cases, whose patients were treated by Injinho-tang, which was selected according to Shanghanlun provisions dualized with Je-Gang(提綱) and Jo-Moon(條文), were analyzed. Results : According to the results of analysis of 2 cases, the patients' diseases were improved when the treatment was applied according to Shanghanlun disease pattern identification diagnostic system and the interpretation of Shanghanlun provisions according to the etymology of Chinese character. Conclusions : These results suggests that Shanghanlun provisions be applied according to etymological interpretation of Chinese character in Shanghanlun disease pattern identification diagnostic system.

Purpose - Transnational corporations (TNCs) have influenced drastic changes (financial services, manufacturing, labor, technology transfer) in Central Eastern Europe (CEE). This paper examines the indirect changes in the CEE pattern of industrial development and market distribution. Research design, data, and methodology - Over 25 years, neighboring (or rival) countries competed to attract TNCs as a double-edged strategy for privatization and debt reduction. Through their experience attracting foreign direct investment (FDI), many countries started to reflect aspects of national capitalism. Countries also began to realize in 2010 that TNCs sought to enter markets with more favorable conditions for export-oriented manufacturing. Results - The analysis reveals that TNC investment strategies were aimed at eliminating local competition to acquire industrial "brown fields" to convert into "green fields." CEE countries have since strengthened their national systems and the support of large-scale state-owned enterprises and small and medium-sized start-up enterprises. Conclusions - CEE has changed based on industrial development and a regional structure of TNC market distribution and associated government policies. The pattern toward flexible markets gives countries the ability to further their economies.

The intelligent trajectory control method that controls moving direction and average velocity for a prosthetic arm is proposed by pattern recognition and force estimations using EMG signals. Also, we propose the real time trajectory planning method which generates continuous accelleration paths using 3 stage linear filters to minimize the impact to human body induced by arm motions and to reduce the muscle fatigue. We use combination of MLP and fuzzy filter for pattern recognition to estimate the direction of a muscle and Hogan's method for the force estimation. EMG signals are acquired by using a amputation simulator and 2 dimensional joystick motion. The simulation results of proposed prosthetic arm control system using the EMG signals show that the arm is effectively followed the desired trajectory depended on estimated force and direction of muscle movements.

Recently, a new technique called Electronic Speckle Pattern Inteferometry(ESPI) has been developed to overcome the drawbacks of existing holography. This technique enable real-time interference fringes to be displayed directly on TV monitor without recourse to any form of photographic processing. This research was carried out for the purpose of applying the vibration analysis method employing Electronic Speckle Pattern Interference technique to the vibration analysis of uniform rectangular cantilever plate, The natural vibration frequencies found by ESPI were in fair agreement with theoretical eigen frequencies acquired using theoretical formula G. B. Warburton proposed.
