Relationship between medicine and iching is what has been followed to be inherited from the period of generation in iching. This writing examined the Thought of the Relation between Medicine and I- ching in Donguibogam. Donguibogam implies the thought that the principles in medicine and iching are same, and is the thought that is broadly spread in Donguibogam. Donguibogam is very rich in yi-yi-study(醫易學)-based contents, which are involved in research subjects of the relation between medicine and iching such as the theory of Taiji(太極) ba gua(八卦), the thought of human and nature, the thought of Yin and Yang, and sign system of gua(卦), and the theory of Image and Number.

We propose a hardware architecture called Multiring which is applicable for various geometrical operations on rectilinear objects such as design rule checking in VLSI layout and many image processing operations including noise suppression and coutour extraction. It has both a fast execution speed and extremely high flexibility. The whole architecture is mainly divided into four parts` I/O between host and Multiring, ring memory, linear processor array and instruction decoder. Data transmission between host and Multiring is bit serial thereby reducing the bandwidth requirement for teh channel and the number of external pins, while each row data in the bit map stored in ring memory is processed in the corresponding processor in full parallelism. Each processor is simultaneously configured by the instruction decoder/controller to perform one of the 16 basic instructions such as Boolean (AND, OR, NOT, and Copy), geometrical(Expand and Shrink), and I/O operations each ring cycle, which gives Multiring maximal flexibility in terms of design rule change or the instruction set enhancement. Correct functional behavior of Multiring was confirmed by successfully running a software simulator having one-to-one structural correspondence to the Multiring hardware.

A computer simulation methiod for costume design has been developed using LUMENA, a generic-purpose 2-dimensional graphic software. In this study the palette, tone chart, fabric chart, styling chart, and costume drawing were constructed on the computer. In costume design simulation, fabric swatches with various colors and patterns were applied to the base garment image taken by using a scanner or a video camera. In this procedure the original 3-dimensional effect was fully retained. Using this simulation method, a number of costume designs could be carried out in short time without actually making the garment. A portfolio including the tone chart, fabric chart, styling chart, costume drawing, and simulation results were made for the purpose of demonstration, using the animation tools of LUMENA.

In this paper, the active backlight control technology with data processing algorithm was developed in order to improve image quality for IPS-mode LCD-TV applications. The image blinking problem caused by repeatedly abrupt change of the backlight luminance was solved by algorithms-Fba(Flexible Boundary algorithm) and Cfa(Cumulative Feedback algorithm)-and the optimized number and space of backlight dimming steps based on perception. In the IPS-mode 42" TFT-LCD panel, the dynamic contrast ratio can be more than twice the typical level by means of lower block luminance and higher white luminance. Additionally, Power consumption and LCD temperature was decreased.

It is a challenging problem to search the intended images from a large number of candidates. Content based image retrieval (CBIR) is the most promising way to tackle this problem, where the most important topic is to measure the similarity of images so as to cover the variance of shape, color, pose, illumination etc. While previous works made significant progresses, their adaption ability to dataset is not fully explored. In this paper, we propose a similarity learning method on the basis of probabilistic generative model, i.e., probabilistic latent semantic analysis (PLSA). It first derives Fisher kernel, a function over the parameters and variables, based on PLSA. Then, the parameters are determined through simultaneously maximizing the log likelihood function of PLSA and the retrieval performance over the training dataset. The main advantages of this work are twofold: (1) deriving similarity measure based on PLSA which fully exploits the data distribution and Bayes inference; (2) learning model parameters by maximizing the fitting of model to data and the retrieval performance simultaneously. The proposed method (PLSA-FK) is empirically evaluated over three datasets, and the results exhibit promising performance.

Soil texture has an important influence on agriculture such as crop selection, movement of nutrient and water, soil electrical conductivity, and crop growth. Conventionally, soil texture has been determined in the laboratory using pipette and hydrometer methods requiring significant amount of time, labor, and cost. Recently, in-situ soil texture classification systems using optical diffuse reflectometry or mechanical resistance have been reported, especially for precision agriculture that needs more data than conventional agriculture. This paper is a part of overall research to develop an in-situ soil texture classification system using image processing. Issues investigated in this study were effects of sensor travel speed and light source and intensity on image quality. When travel speed of image sensor increased from 0 to 10 mm/s, travel distance and number of pixel were increased to 3.30 mm and 9.4, respectively. This travel distances were not negligible even at a speed of 2 mm/s (i.e., 0.66 mm and 1.4), and image degradation was significant. Tests for effects of illumination intensity showed that 7 to 11 Lux seemed a good condition minimizing shade and reflection. When soil water content increased, illumination intensity should be greater to compensate decrease in brightness. Results of the paper would be useful for construction, test, and application of the sensor.

Today, the hotel industry in a whole are facing serious problems with a number of reasons. To overcome this situation, Customer-Oriented Marketing is considered to be a solution for the hotel F & B management, due to the potential of F & B department. The main purpose of this study was to present the Food and Beverage Marketing Mix Strategies suitable for the market characteristics. To achieve the purpose of this study, theoretical and empirical approaches were used. In review of theoritical background, basic concepts and characteristics of hotel F & B, hotel F & B marketing environment, and hotel F & B marketing mix were studied. Based on the theoritical studies and previous studies, F & B marketing mix sub-components were chosen. In this research, F & B 5P's and 1I marketing mix are discussed, they are Product, Price, Promotion, People, Physical evidence and Image. Through the survey, a number of important segment markets are emerged, which lead to essential segment markets ; business, conference and leisure market. F & B marketing mix strategies as follows. First, for the physical evidence mix, to build up the position as deluxe hotels, it is necessary to matte an investment in technical and decorative components. Second, for the people mix, to assure the service quality, the education and training programs for employee are required. Third, for the image mix, to ensure the image of hotel brand strength, the consideration for public area layout, restaurant and bar ambience, and green policy are required. Fourth, for the product and price mix, to differentiate the F & B, it is necessary to offer thorned and ethnic cuisine, and signature restaurants. Fifth, for the promotion mix, to attract more cumstomers, creative and various promotion activities, and long-term investment in customer-oriented marketing are required. There were some limitations in this study. That is, most of hotels don't operate the concrete and effective F & B marketing, have difficulty in getting data base for F & B customer. Despite their limitations, this study add some values to hotel F & B management in that it introduce the service marketing mix strategies to hotel F & B marketing.

A newmethod of fast mask operators for edge detection is proposed, which is based on the matrix factorization. The output of each component in the multi-directional mask operator is obtained adding every image pixels in the mask area weighting by corresponding mask element. Therefore, it is same as the result of matrix-vector multiplication like one dimensional transform, i, e, , trasnform of an image vector surrounded by mask with a transform matrix consisted of all the elements of eack mask row by row. In this paper, for the Sobel and Prewitt operators, we find the transform matrices, add up the number of operations factoring these matrices and compare the performances of the proposed method and the standard method. As a result, the number of operations with the proposed method, for Sobel and prewitt operators, without any extra storage element, are reduced by 42.85% and 50% of the standard operations, respectively and in case of an image having 100x100 pixels, the proposed Sobel operator with 301 extra storage locations can be computed by 35.93% of the standard method.
