This study is aimed at applying the philosophical concept of "$diff{\acute{e}}rance$" to contemporary men's fashion design, which could effectively show the shift in thinking. For the study method, the author examined the theoretical background of deconstruction and prepared the standard of analysis by organizing the concept of "$diff{\acute{e}}rance$," which exists at the center of philosophy. This study selected the three most popular brands: Maison Margiela, Comme des Garcons, and Yohji Yamamoto. The results are as follows. First, there is expression of perpetual reservation emphasizing time. This includes texture, patchworks, hems with ladder, and exposure of seam that expresses the trace of time flow and delayed delivery of immediate meaning, and the expression creates delay between major and minor and leads to consistent role exchange. Second, the trace of blank that emphasizes the space gives a visual sense of weight on spares with the intentionally granted space, as well as the space that is the trace of trace and creates a sense of depth through the direction of empty space. Third, the space created in the process of wearing cloth is visualized, the structure of clothing is deconstructed, and the movement from the process recomposes the shape of space and expands the definition that enables expansion of time and space. Fourth, the undetermined relationship expresses the border of time and space visually and deconstructs time and space. The approaches are mostly constructive, demonstrating an avant-garde form of clothes-wearing to show the non-form or imbalance condition.

Online retailers' offline channel expansion is rapidly growing as an important consumer incentive strategy, despite the enormous initial costs of establishing a store. This study focuses on the offline channel operation of online shopping malls, and examines the effects and influencing factors of the channel expansion strategy from a consumer perspective. In-depth interviews were conducted with ten customers in their 20s and 30s who had visited online retailers' stores or purchased products. Major issues were extracted based on the framework of a channel effect mechanism proposed by Cao and Li (2015). Subsequently, it was found that existing online retailers could enhance brand image and perception by expanding their channels to offline stores. It was also emphasized that the consumer trust on the quality of the product in offline stores is a key variable, and it has a significant influence on consumer's continuous purchase and revisit intention. This study showed that borderless channel integration was the most important task when expanding channels of online retailers. So it will be necessary to strive for an omni-channel strategy so that channel integration can be strategically executed and consumers can interact regardless of channels.

Patricia Waugh once regarded modernism fiction as 'the struggle for personal autonomy' against the opposition existing social institutions and conventions. Michael Cunningham's characterizations of Virginia Woolf and Septimus in The Hours show the two contrasting reactions to individual alienation and mental dissolution in the modern era. As the personifications of endurance and self-destruction against the mechanical power of contemporary world, Woolf and Septimus consist of just the world of diptych where the woman's role is confined to the angel in the house. By creating Mrs. Brown based upon his own alienated mother image, however, Cunningham succeeds in representing the more dramatically vivid world of triptych where woman can have her own room and self-realization despite still facing the dilemma of the traditional family. Accepting Joycean Bloom's optimistic and relaxing way of life in part, Mrs. Brown connects the labyrinths between the author's (and also Richard's) alienation with the theme of celebration of the life. Clarissa in postmodern New York setting is still a concealed and mystified character. Similar to Mrs. Dalloway, on the one hand Clarissa watches other people's tragedy with compassion. Cunningham's Clarissa, on the other hand, is no longer seeking for either winning or defeat in the spectacular world unlike her predecessors. In many resilient attitudes of everyday life Clarissa is closest to Mrs. Brown whom Virginia Woolf originally hopes to describe. Without any fear or rage toward the society Clarissa witnesses and achieves "the humanity, humour, depth" of female values by successfully turning the trivial life into an epic journey.

An application of the instrumented indentation technique has been expanded from the measurements of hardness and elastic modulus to the analysis of residual stress. A slope of the indentation loading curve increases (or decreases) according to compressive (or tensile) residual stress. A theoretical equation has been established for quantifying residual stress from the slope change. However, a precise observation of the remnant indents is indispensible because the theoretical approach needs actual contact information. In addition, the conventional hardness test is still used for predicting the residual stress distribution of welded joints. Thus, we observed the three-dimensional morphologies of the remnant indents formed on artificial stress states and analyzed stress effects on morphological recovery of the indents. First, a depth recovery ratio, which has been regarded as a sensitive stress indicator, did not show a clear dependency with the residual stress. Thus an analysis on volumetric recovery was tried in this study and yielded a inverse proportional behavior with the residual stress. In addition, an elastic to plastic volume recovery ratio showed more significant correlation with the residual stress.

The aim of this study is to investigate morphological characteristics of Hanbok images in children's books and propose a direction for the modernization and globalization of traditional culture. This study examines 43 children's books by contemporary foreign illustrators that contain Hanbok illustrations and analyzes them from postcolonial perspective. The results include the following three attributes: first, the transformation of clothing structure and donning method that confuse fundamentals of Korean costume; second, the Westernization of silhouette drawing with tailored garments analogous to Western dress; and third, extension to East Asian dress that represents Hanbok mixed with Chinese or Japanese costume and use what is considered to be the East Asian patterns instead of Korean traditional ones. These attributes are based on Eurocentrism, which expresses and interprets the East from the Western view point with continuously distorted image of the East. Korean illustrators also painted Hanbok incorrectly, which could influence foreign illustrators. Nevertheless, traditional dress illustrated in various ways has artistic value and has a popular global impression. Further, it enables children to experience either own or other cultures through dress illustrations. Thus, the outsider requires an in-depth understanding of other cultures, while the insider needs a critical perception of their own culture as described by others while revisiting the original resources. Furthermore, we suggest follow-up research on Hanbok for subsequent generations; publishing translated books on various topics, producing and disseminating a primer for diverse readers, and essentially receiving counsel from experts.

The article seeks to explore Ukrainian media art and its features in a global context. In particular, it performs an in-depth analysis of the stages of its development from video art of the 1990s, media installations of the 2000s, and to various digital and VR technologies today. Due to historical circumstances, the development of media art was quite rapid, as young artists sought to gain new experience in media art. Most often, their experience was broadened through international cooperation and studying abroad. The paper analyzes the presentation of Ukrainian media art outside the country during 1993-2020 and distinguishes the main thematic areas of the artists' work. It examines how artists present and reveal the peculiarities of the Ukrainian worldview, aesthetics, and culture through the problematization of certain aspects and themes in their work. Specifically, among the principal topics which are problematized in the work of media artists are a sensory experience, limited sensory capabilities, gender issues, the Chernobyl tragedy, the development of utopian models of the city, and global communication. The leading themes of Ukrainian artists also include revolution and war. Notably, political and social sentiments determine the unique energy and vitality of contemporary Ukrainian art, create a revolutionary creative environment, and unite media artists in group art projects. It is concluded that by showing, exhibiting, and presenting them outside the country, artists shape the image of Ukrainian art in a global context.

Purpose: Direct intraoral scanning and superimposing methods have recently been applied to measure the dimensions of periodontal tissues. The aim of this study was to analyze various correlations between labial gingival thickness and underlying alveolar bone thickness, as well as clinical parameters among 3 tooth types (central incisors, lateral incisors, and canines) using a digital method. Methods: In 20 periodontally healthy subjects, cone-beam computed tomography images and intraoral scanned files were obtained. Measurements of labial alveolar bone and gingival thickness at the central incisors, lateral incisors, and canines were performed at points 0-5 mm from the alveolar crest on the superimposed images. Clinical parameters including the crown width/crown length ratio, keratinized gingival width, gingival scallop, and transparency of the periodontal probe through the gingival sulcus were examined. Results: Gingival thickness at the alveolar crest level was positively correlated with the thickness of the alveolar bone plate (P<0.05). The central incisors revealed a strong correlation between labial alveolar bone thickness at 1 and 2 mm, respectively, inferior to the alveolar crest and the thickness of the gingiva at the alveolar crest line (G0), whereas G0 and labial bone thickness at every level were positively correlated in the lateral incisors and canines. No significant correlations were found between clinical parameters and hard or soft tissue thickness. Conclusions: Gingival thickness at the alveolar crest level revealed a positive correlation with labial alveolar bone thickness, although this correlation at identical depth levels was not significant. Gingival thickness, at or under the alveolar crest level, was not associated with the clinical parameters of the gingival features, such as the crown form, gingival scallop, or keratinized gingival width.

The automatic defect sorting function of machinery parts is being introduced to the automation of the manufacturing process. In the final stage of automation of the manufacturing process, it is necessary to apply computer vision rather than human visual judgment to determine whether there is a defect. In this paper, we introduce a deep learning method to improve the classification performance of typical mechanical parts, such as welding parts, galvanized round plugs, and electro galvanized nuts, based on the results of experiments. In the case of poor welding, the method to further increase the depth of layer of the basic deep learning model was effective, and in the case of a circular plug, the surrounding data outside the defective target area affected it, so it could be solved through an appropriate pre-processing technique. Finally, in the case of a nut plated with zinc, since it receives data from multiple cameras due to its three-dimensional structure, it is greatly affected by lighting and has a problem in that it also affects the background image. To solve this problem, methods such as two-dimensional connectivity were applied in the object segmentation preprocessing process. Although the experiments suggested that the proposed methods are effective, most of the provided good/defective images data sets are relatively small, which may cause a learning balance problem of the deep learning model, so we plan to secure more data in the future.
