This study is what tried to examine the importance of material in industrial design. Then, if planning is to start of product design, the use of material is the last step to complete design. Design material has existed from the time before mankind were born, and the new material which is useful for human beings is developing rapidly. It is no exaggeration to say that our environment is the aggregation of material which was surrounded with us. Then, material has the timely, spatial and cultural feature as well as physical feature. Besides, all sorts of functions of communicating information are being contained in accordance with the character of material. The outside surface of material has the function to develop the sense organ of human beings. This study examines 4 kinds of cultural features in design materials and shown by findings is as follows : Rrst is the technical progressivity to lead new Design form. Second is the symbolic nature to perform the communication function. Third is the sensible attribute to develop surface effect of Design material. Fourth is the future-oriented nature to convince the future such as new material and technology etc. Thus, so as to perform the competitive product design, it is important to grasp the harmony between material and design, structure and processing, and the substantial meaning that the material has and apply them properly, above all. Because the discovery of material will be the measure to forecast future design.

This paper is the first geomorphological research on TAENGNIGI which is famous for old geography book in Korea. The purpose of this paper is to explain TAENGNIGI in modem geomorphological viewpoint and then, lay the foundation for establising Korean style geomorphological terms. It also analyzes TAENGNIGI from Lee, Jung-Hwan(the authority of TAENGNIGI's geomorphological viewpoint. The main results are summarized as follows. Firstly, It is estimated that TAENGNIGI is a geography book including human and physical geography. Secondly, in spite of Lee, Jung-Hwan's some metaphysical explanation of feng-shui in TAENGNIGI. his geomorphological appreciative eye is excellent. Thirdly, it is possible that a Korean style geomorphological term will be established based upon the result of this paper on TAENGNIGI. Fourthly, Lee, Jung-Hwan indicted geography(地理), profit(生利), human nature(人心), landscape(山水) as factors in selecting of people's dwelling place(可居地) and he described that geography(mainly physical geography) was mostly important among the four factors mentioned in selecting of people's dwelling place. Especially he also mentioned that good landscapes have a favorable influence upon the forming of people's character.

The pursuit of freedom by the individual--desire to be liberated from all forms of restrictions-- is one of the defining character-istic of the modern society. As costume is, in part, a product of the spirit of the times, it was only natural that this desire for freedom would find its expression in modern costume as well. Among various forms of restrictions, differentiaton by sex has placed one of the most significant binding influences on individual behavior. From early times, the dichotomous division by sex was incorporated into the disign of costume, and the traditional differestriction of costume by sex imposed a significant restriction on the background,“the modern androhynous look”was born as a by-product of the sexual liberation movement in the second half of the 20th century, based on the concept of the individual as a complete human being rather than as a member exclusively of either the male or the female sex. This paper seeks to examine the androgynous look within a coherent theoretical frame-work, and explore new design possibilities by analyzing and understanding the visual characteristics of the androgynous look. In addition, this paper seeks to define the functional aspects of the androgynous look based on the premise that costume is an embodiment of the spirit of the times. As for research methodology, both theoretical and historical methods are employed. Through a theoretical examination of historical documents, the meaning of the androgynous look is explored from various angles, and order to examine its place in modern fashion, an-drogynous styles are categorized and system atically analyzed. The main findings of the paper can be summarized as follows : 1. Androgyny is a compound word consisting of“andro-”(meaning man) and“gyn-”(meaning woman). In modern times, this word has been associated with the socio-cultural aspect of gender rather than the physical or physiological aspect with the pshchological characteristics of the male and female sexes. Androgynous styles also appear in fashion and general arts such as drama, film, dance, and music. In fashion, the androgynous look, represented by the visual superimposition of “masculine”and “faminine”elements, has emerged as a major element of the 20th-century costume, and has gained broad acceptance among those free spirits wishing to be liberated from the conventional conceptions of male clothing, and the unisex look. 3. The androgynous look in modern fashion reflects the spirit of the 20th century society and culture, and performs various functions as follows : expression of fun, change in gender roles, expression of the inner consciousness, and pursuit of the ideal human type.

This study is an introductory survey of the labyrinth/maze in gardens. The term 'garden labyrinth' may seem an oxymoron given that the garden represents the terrestrial paradise, while the labyrinth is a symbol of the most chaotic face of the world. In etymological and ontological terms, however, gardens are enclosed places and this characteristic corresponds to the character of the labyrinth, which is the one of the oldest signs in human civilization, symbolizing the paths of human life filled with uncertainty and complexity. The garden labyrinth has developed in various forms and shapes since the Renaissance period. Literature and paintings contributed to the dissemination of the concepts of the garden labyrinth, especially in the form of the 'garden of love'. While the labyrinths in ancient and medieval times focused on plane shapes and symbolic and/or spiritual meanings, later garden labyrinths emphasized the three dimensional form and synesthetic pleasures. New patterns, which deviated from the classical unicursal form, emerged in the Petit Parc at Versailles in the 17th century. The garden labyrinth/maze was easy to adopt in formal gardens because of its geometric form, but for that reason, it went on to decline during the fad of picturesque garden. In this study, a brief history of labyrinths, the patterns, forms, and arrangement of the garden labyrinths in the formal gardens of the Renaissance and Baroque periods and its meanings are reviewed.

In Web registration pages and online polling applications, CAPTCHA(Completely Automated Public Turing Test To Tell Computers and Human Apart) is used for distinguishing human users from automated programs. Text-based CAPTCHAs have been widely used in many popular Web sites in which distorted text is used. However, because the advanced optical character recognition techniques can recognize the distorted texts, the reliability becomes low. Image-based CAPTCHAs have been proposed to improve the reliability of the text-based CAPTCHAs. However, these systems also are known as having some drawbacks. First, some image-based CAPTCHA systems with small number of image files in their image dictionary is not so reliable since attacker can recognize images by repeated executions of machine learning programs. Second, users may feel uncomfortable since they have to try CAPTCHA tests repeatedly when they fail to input a correct keyword. Third, some image-base CAPTCHAs require high communication cost since they should send several image files for one CAPTCHA. To solve these problems of image-based CAPTCHA, this paper proposes a new CAPTCHA based on both image and text. In this system, an image and keywords are integrated into one CAPTCHA image to give user a hint for the answer keyword. The proposed CAPTCHA can help users to input easily the answer keyword with the hint in the fused image. Also, the proposed system can reduce the communication costs since it uses only a fused image file for one CAPTCHA. To improve the reliability of the image-text fusion CAPTCHA, we also propose a dynamic building method of large image dictionary from gathering huge amount of images from theinternet with filtering phase for preserving the correctness of CAPTCHA images. In this paper, we proved that the proposed image-text fusion CAPTCHA provides users more convenience and high reliability than the image-based CAPTCHA through experiments.

This article aims to investigate the geographical distribution and the cultural, historical, and symbolic meanings of the place names in the area of Bukhansanseong (Fortress), and to basically suggest the several features which have happened throughout the process of toponymic changes. In order to realize the purpose of the article, I collected the chronological toponymic data, particularly focusing on the Bukhanji (Record of Bukhansanseong, 1745) in which the most existing place names related to Bukhansanseong are recorded. In the meantime, I proposed the character of distributions and types of the physical, human place names according to the rear-part of toponymic morpheme, i.e. the generic name. Moreover, selecting the main place names such as 'Bukhansan', etc., I analyzed some features on the toponymic meanings and changes in accordance with the fore-part of toponymic morpheme, the specific name. Consequently, I identified the facts that the name of 'Bukhansan' in the era of the Three Kingdoms, 'Samgaksan' in the Goryeo Dynasty, and again 'Bukhansan' or 'Buksan' in the Joseon Dynasty era had been primarily called. And then the place name, 'Bukhansan' has been officially named until now since constructing the Bukhansanseong Fortress in 1711. Meanwhile, the physical place names related to mountainous and fluvial topography, the place names of artificial facilities such as a mountain fortress on this geographical environment, and especially Buddhistic place names which was named and identified by Buddhist monk, Seongneung who wrote the Bukhanji, representing the Buddhistic identity and ideology, form a large majority of the place names within Bukhansanseong.

High-density micromass culture was needed to take three dimensions culture with ASCs(adipose derived stromal cells) and chondrogenesis. However, the synthetic polymer has hydrophobic character and low affinity to cells and other biomolecules. Therefore, the surface modification without changes of physical and chemical properties is necessary for more suitable condition to cells and biomolecules. This study was performed to investigate the effect of surface modification of poly (lactic-co-glycolic acid)(PLGA) scaffold by plasma treatment (P(+)) on the adhesion, proliferation and chondrogenesis of ASCs, and not plasma treatment (P(-)). ASCs were isolated from human subcutaneous adipose tissue obtained by lipectomy and liposuction. At 1 hour 30 minutes and 3days after cell seeding onto the P(-) group and the P(+) group, total DNA amount of attached and proliferated ASCs markedly increased in the P(+) group (p < 0.05). The changes of the actin under confocal microscope were done for evaluation of cellular affinity, at 1 hour 30 minutes, the shape of the cells was spherical form in all group. At 3rd day, the shape of the cells was fiber network form and finely arranged in P(+) group rather than in P(-) group. RT-PCR analysis of cartilage-specific type II collagen and link protein were expressed in 1, 2 weeks of induction. Amount of Glycoaminoglycan (GAG) markedly increased in P(+) group(p < 0.05). In a week, extracellular matrix was not observed in the Alcian blue and Safranin O staining. However in 2 weeks, it was observed that sulfated proteoglycan increased in P(+) group rather than in P(-) group. In conclusion, we recognized that plasma treatment of PLGA scaffold could increase the hydrophilic property of cells, and provide suitable environment for high-density micromass culture to chondrogenesis

ROC(Receiver Operating Characteristic)curve is the method that estimate detected insignificant signal from the human's sense of sight, it has been raised excellent results. In this study, we evaluate image quality and equipment character by obtaining a chest image from CR(Computed Radiography) and DDR(Direct Digital radiography) using the human chest phantom, The parameter of exposure for obtaining chest image was 120 kVp/3.2 mAs and the SID(Source to Image Distance) was 180cm. The images were obtained by CR(AGFA MD 4.0 General plate, JAPAN) and DDR(HOLOGIC nDirect Ray, USA). Using some pieces of Aluminum and stone for expressing regions, then attached them on the heart, lung and thoracic vertebrae of the phantom. 29 persons hold radiology degrees were participated in ROC analysis. As a result of the ROC analysis, TPF(true positive fraction) and FPF(false positive fraction) of DDR and CR are 0.552 and 0.474 and 0.629 and 0.405, respectively. By using the results, the ROC curve of CR has higher image quality than DDR. According to the theory, DDR has the higher image quality than CR in chest X-ray image. But, CR has the higher image quality than DDR. quality of DDR inserted the enhance board. The results confirmed that image post-processing is important element decipherment of clinical.

21th century that is repealing change is making the world that can enjoy human spiritual character and freedom wholeheartedly. Therefore, meet hereupon arid design may have to bring conversion to position of beginning that can be software at position that is hardware look raw and result look who is wrapping last result arts provide cause. Therefore, user supposes that do difficult form in that recognize things form, and that difference about attribution reaction may do differ and contradictory attribution reaction while specially 40s and 50s recognize product form laying stress on external form embodiment of product form meaning by guess and this research compares and investigates attribution process for human's attribution reaction instinct and attribution reaction type through scientific, theoretical considerations about form and things theoretically and defined cause reasoning in design. And designed product that things are recognized whether felt thing in product form is what hearing example relation sex between analysis and form of meaning induction by attribution leading person about subjective estimation reaction through literature arrange, and analyze and defined if cause some effect to designed product because drawing urea about attribution reaction through an experiment. And presented model about design access method and forward pratical use possibility and hereafter subject together with conclusion.
