Purpose: This study was conducted to describe qualitatively the entities of nurse's experiences in general hospitals and to suggest basic data guiding research on developing Standards of clinical nursing practice in Korea. Method: Fourteen nurses working at general hospitals with over 300 beds in Seoul were interviewed in-depth until saturation using tape-recorders and transcription. Result: The central theme of clinical nursing practice experienced by subjects was "being with clients" that means accepting client's personal character, solving client's needs and providing client-centered nursing. A also "being with clients" was felt to be the responsibility of nurses which was learned from their nursing schools. The nursing strategies performed in order to be with patients were proving skillful nursing techniques, accepting, educating, emotional support, advocating, and self-reflecting, the subjects experienced somewhat problematic affects such as difficulties in interpersonal relationship, work overload, negative image of nursing, deficit of self-confidence for nursing actions, poor working conditions, and unfair treatment. Nurses at the hospital practiced with pride when they felt that they were accepted by clients. Conclusion: Further research is needed to analysis problems in clinical practice and the comparison of nurses' experiences of clinical practice, with nurses' experiences in various settings.

In this paper, we was designed three-dimensional face recognition algorithm using polynomial based RBFNNs and proposed method to calculate the recognition performance. In case of two-dimensional face recognition, the recognition performance is reduced by the external environment like facial pose and lighting. In order to compensate for these shortcomings, we perform face recognition by obtaining three-dimensional images. obtain face image using three-dimension scanner before the face recognition and obtain the front facial form using pose-compensation. And the depth value of the face is extracting using Point Signature method. The extracted data as high-dimensional data may cause problems in accompany the training and recognition. so use dimension reduction data using PCA algorithm. accompany parameter optimization using optimization algorithm for effective training. Each recognition performance confirm using PSO, DE, GA algorithm.

Synthetic zinc wave employs Pulsed plane wave as transmit beam with linear time delay curve. The received echoes in different transmit directions at different transmit times are superposed at imaging Points with Proper time delay compensation using synthetic focusing scheme. This scheme. which uses full aperture in transmit, obtains a high SNR image, and also features high lateral resolution by using two way dynamic focusing at all imaging depths. In this Paper, we consider the Problems in realization of synthetic zinc wave. Also. we have applied the scheme to obtain phantom and in-vivo images using a linear array of 5 MHz. In phantom test. experimental images show high resolution over a more extended imaging depth than conventional fixed Point transmit and receive dynamic focusing schemes In-vivo images show that the resolution could not overcome conventional focusing systems because of motion blurring and(or) aberration of tissue. but the frame rate tan be increased by a factor of more than 5 compared to conventional focusing schemes. with competitive resolution at all imaging depths .

The modern trend in costumes, influenced by postmodernism, is to use of various patterns and images borrowed from diverse cultures of many ethnic groups. The Yi tribe studied in this paper is miner ethnic group in China, whose traditional costume is very splendid and modern. In addition, its embroidery or $appliqu{\acute{e}}$ pattern have a high artistic value in that its shapes are diverse, splendid and each one has its own peculiar elegance. As for the research method, I examined the Yi tribe's history, culture, traditional costumes and patterns through related books, research papers and inter web sites. As for the result, the Yi tribe's costumes consisted of a jacket, trousers or a skirt, an apron and a belt. Although the favorite color of the costume is black color, there are splendid embroidery or $appliqu{\acute{e}}$ decorations with the colors of red, yellow, green and purple on the chest or shoulder part of a jacket, the adjusting lines, cuffs or a part of a trousers and aprons. Patterns in their traditional clothing also show details that depict traditional cultural ideas that have long been formed in various fields, such as aesthetics, religion, philosophy, and customs. Moreover, most patterns displayed in their traditional clothing contain nature motifs and represent unique and beautiful designs; some patterns are even reminiscent of abstract paintings by modern artists. In conclusion, the traditional patterns of Chinese ethnic minorities reflect the values and notions of these races as well as decorative magnificence and a unique spiritual image. In other words, traditional patterns indicate the spiritual depth or symbolic stories beyond mere formative beauty.

A web based virtual try-on provides customers a more enjoyable shopping experience that visualize clothes on personal mannequin. The researchers compared virtual fitting models which were developed in 2000 at Korea and in 2000 and 2002 at U.S. The results of this study as follows: The information about user's body size was required to input for selection of a virtual fitting model. 7 to 19 different body size, shape, and face features including weight and height were needed for visualizing virtual fitting model. The body type of the U.S virtual fitting model(My virtual model) was selected by front view silhouette for women, and by shoulder width and midriff silhouette for men. The more detailed information was required for developing Korean virtual fitting model. The additional body size information required in the site were leg and arm lengths, waist length, and thigh and ankle circumferences. The body proportion of Korean cyber personal mannequin was longer and narrower than the U.S cyber personal mannequin. It was recommended that standardized body length, width, and depth proportions calculated from national anthropometric data must be applied for developing Korean virtual fitting model. With application of more detailed information on face feature and advanced graphic image technology the 'My virtual model in 2002 resembled the human body shape of various race.

This study analyzes historical drama costumes as a domain of popular culture through an examination of the changing process, factors, and design characteristics of historical drama costumes according to trend changes in historical dramas after the 2000s. Public interest in Korean traditional clothing has grown due to the historical drama fever. Research results are as follows. First, historical dramas are divided into: authentic historical dramas, popular dramas, and fusion dramas. Historical drama costumes show characters' status and roles to help viewers become absorbed in dramas and increase understanding the historical periods and knowledge. Second, the characteristics of TV historical drama costumes (according to changes of the historical dramas according to 2000) brought diversification as they are diversified by period, genre, and character and costumes which are suitable for them additionally resurfaced. Third, as for the design characteristics by type in TV historical costume after 2000s, authentic historical dramas' design was done by comparatively in-depth historical research based on historical materials to help public understand the past. Popular historical drama costumes are based on history, but the forms of costumes were emphasized (or exaggerated); in addition, colors, subjects, and patterns were modified to emphasize image beauty, dramas' atmosphere, and characters by reflecting intention. The fusion of historical dramas' costumes attracted the attention of the public about Korean designs that harmonized tradition with modernity to actively reflect current trends in past periods and show new types of creative design.

Cold water observed at sea surface near the southeastern coast of Korea in summers 1982 and 1983 was studied by using data of hydrography, sea level, wind and satellite image. In summer season when water column shows 3-layered structure a "full" upwelling occurs by southwesterly transient wind continuing for several days. During upwelling event, surface water of high temperature moved offshore, middle water of low temperature outcropped to the sea surface, and sea level was lowered, however, equilibrium depth of surface layer was not changed. It may be concluded that cold water at the surface originates from middle layer and strong surface front is a result of surfacing of seasonal thermocline. In order to see the relationship between position of surface front and wind input, a model of Csanady (1982) was applied in a rigid lid approximation. The results show that frontal position can be determined by wind input and water structure near the southeastern coast of Korea. Cold water in summer can appear at the sea surface only when there is wind larger than a minimum wind impulse of order $10m^2/sec$.

The purpose of this study is to find fitness of brassiere by means of body measuring value, its variation volume, the evaluation of perceptive image, and the evaluation of the sense of wearing. The results were as follows; 1) According to comparison for body measuring value before and after wearing brassiere, bust point (B.P.) height, lower bust height, upper chest circumference, chest circumference, and bust depth are increased, and lower chest circumference, bust point breadth, shoulder middle point - B.P., B.P. -under bust, and cup horizontal girth are decreased. 2) The difference of variation volume by material is not accepted. The part above $20\%$ at variation rate is under the region of the armpit, that is, the region connected arm from the back. 3) The subjects replied that they wore the brassiere in order to compensate the breast and needed to wear it regardless of thiness and obesity. They wore the brassiere in order to dress themselves in good shape, and felt that it put pressure upon the body, while it had nothing to do with adjusting bodily temperature and gave the sense of security. 4) The estimate of the sense of wearing by material is recognized as the difference of the attention at attentive level $1\%$. The multiple factor analysis of each item in the sense of wearing showed that the items which are explained over $90\%$ by common factors are '1. Unpreasant in touch', '2. The part of edge is haggard', '15. Not to be fit'.

In this paper, a slit light laser range finding method using perspective warping calibration is proposed. This approach has an advantage to acquire relatively high accuracy, although the optical system is nonlinear. In the calibration, we detect the calibration points which are marked on the calibration panel and acquire the center position of the slit light laser in the image, which are used for computing the real positions of the slit light by using perspective warping. A calibration file is obtained by integrating the calibration data with the transition of the panel. The range data is acquired by interpolating the center position of the slit light laser to the calibration coordinates. Experimental results show that the proposed method provides the accuracy of 0.08mm error in depth range of 130mm with the low cost optical system.
