  • Debris flows are a natural hazard which looks like a combination of flood, land and rock slide. Large rainfall in July 2006 produced several large scale debris flows and many small debris flows that resulted in loss of life and considerable property and highway damage, as was widely reported in the national media. The hazard "debris flow" is still insufficiently researched Furthermore debris flows are very hard to predict. In this paper, a general over view of the debris flow problems along the highway, a generic way for the design and dimensioning of flexible barrier systems will be presented. A brief description of the various unique barrier types will be provided, too. The future for these barrier concepts looks promising because these barriers represent the state of art for such applications and are superior to many other available options.

  • Measurement of convergence was/is carried out manually throughout the world for tunnels under construction. However, manual method has certain limitations in terms of applicability for the tunnels in operation. This paper describes state of the art of convergence monitoring systems which are available for measuring displacement of existing tunnels. These technologies are analyzed as follows: 1 The Sofo system using the fiber optic sensors has been applied to the stress measurement of the tunnel lining. It has not yet been used for the monitoring of tunnel convergence because of its cost and reliability 2. A TPMS(Tunnel Profile Monitoring System) using tilt sensors and displacement sensors is used for the convergence monitoring of highway tunnels, subway tunnels and underground ducts. 3. A BCS(Bassett Convergence System) using a pair of tilt sensors can be used for the convergence monitoring of tunnels, however the accuracy of the measurement has to be improved because it uses AC input voltage during data acquisition. The system has to be validated before it can be applied to the tunnels in operation. Convergence monitoring systems using TPMS and/or BCS are recommended to be evaluated and improved by a series or tests in tunnels under construction in order to be applied to the main measuring section and the tunnels in operation.

  • The purpose of this study is to examine the value of grotesque fashion and to predict the future fashion trend. The grotesque originates the formative art. It emerges towards of a century or transitional period in most case. In particular, it was used as the expressive method of an individual's inside and a satire on society through the work of artists in the Middle Age, the renaissance, the sym-bolism, the dadaism, the surrealism, the pop art, the technology art, and the post-modernism, etc. The grotesque in fashion is represented in the work of avant-garde fashion designers who lead the high fashion. The grotesque fashion which was combined with an image of non-formality, non-rationality, an absurdity and reality. It has been begun shape of female dress in the renaissance. Afterwards, it was represented in extremely exaggerated and distorted pop art, hippies' fashion in the 1960's. In the 1970's, it was reflected in genderless rock star and destructive punk fashion. It was also represented in the androgynous fashion which was combined with both sexes, the goth/gothic fashion which was expressed with a realistic and fanciful shape and the tattoo of skin-head in the 1980's. In the 1990's, the grungy look which was dirty and the cyber punk fashion. In general, it was also expressed by the avant-garde fashion designers. To sum up, a grotesque fashion which is expressed by experimental designers is classified into four shapes. 1, Union of some extraneous is expressed as different kinds of fashion theme, such as abnormality of texture, uses of surrealistic elements and chaos of sex. Although it appears that the abnormal union of grotesque has only discord and collision, it also shows a feeling of freedom for the tension. 2. Introduction of real and fanciful image is expressed as a cyborg, realistic description of disgusting animal skin and aggressive shape. Especially, it is worth while to notice Tierre Mugler and Alexander Macqueen's work which expressed the shape of mingling human of Middle Age. 3. distortion or exaggeration is expressed as an unformed shape, the exaggeration of a clothing size, the abnormal exaggeration of human body and the ignorance of clothing form. 4. Introduction of a disgusting image is expressed as an extremity of reality, motifs of death, clothing material of disgusting hair and the ostentation of sex. Motto which leads modern fashion is something new and shocking. The grotesque fashion is an expression of eagerness for something new. It often show something ironic in the form of humor which is embedded in an abnormal and shocking pattern. The grotesque fashion is represented as an extreme beauty. It will stand as an important element of the future fashion and as a particular style with the change and fluidity.

  • This study aims on providing a design technique that expresses aesthetical elements by arranging the analysis of sensual beauty into detailed elements of design from music video outfits by genre of pop music, by observing music videos of female vocalists chosen from each genre of pop music focusing on their fashion. The results of this study are the following. 1. In the genre rock, the sensual beauty of female were expressed with a boyish and neutral style using texture such as leather or denim, and such style had the effect of emphasizing their feminine side even more. 2. In the genre dance music, exposure is extensive compared to other genre using sexy or lingerie look, and I found an ambivalent style of feminism with clothes in the form of drapery using textures such as chiffon and silk, and femme fatale style with textures adhering to the body such as leggings, leotard, and bodysuit. 3. In the genre of rap and hip-hop, clothes from casual and costume-play style were found using training jersey, t-shirt, and denim pants, and emphasized the sensual beauty of women by showing a silhouette with short length and fitting style using shiny textures. 4. In the genre of R&B, there were diverse outfits that suits the characteristics of characters appearing in the stories, or the situation of the story since there are many dramatic representation in the form of story Especially in case of female characters, the feminine side was emphasized staging a feminine style by wearing dresses with the texture of chiffon and silk. Exposure was restrained compared to other genre.

  • Debris flows are a natural hazard which looks like a combination of flood, land and rock slide. Large rainfall in July 2006 produced several large scale debris flows and many small debris flows that resulted in loss of life and considerable property and railway damage, as was widely reported in the national media. The hazard "debris flow" is still insufficiently researched. Furthermore debris flows are very hard to predict. Flexible Ring net barriers are multi-functional mitigation devices commonly applied to rock fall or floating wood protection in floods, snow avalanches and also mud flows or granular debris flows, if properly dimensioned for the process or processes for which they are intended. Overtopping of the barriers by debris flows and sediment transport is possible, supporting the design concept that a series of barriers may be used to stop volumes of debris larger than are possible using only one barrier. The future for these barrier concepts looks promising because these barriers represent the state of art for such applications and are superior to many other available options.

  • The prediction of structural mechanical behaviors is vital important to early perceive the abnormal conditions and avoid the occurrence of disasters. Especially for underground engineering, complex geological conditions make the structure more prone to disasters. Aiming at solving the problems existing in previous studies, such as incomplete consideration factors and can only predict the continuous performance, the deep attention fused temporal convolution network (DATCN) is proposed in this paper to predict the spatial mechanical behaviors of structure, which integrates both the temporal effect and spatial effect and realize the cross-time prediction. The temporal convolution network (TCN) and self-attention mechanism are employed to learn the temporal correlation of each monitoring point and the spatial correlation among different points, respectively. Then, the predicted result obtained from DATCN is compared with that obtained from some classical baselines, including SVR, LR, MLP, and RNNs. Also, the parameters involved in DATCN are discussed to optimize the prediction ability. The prediction result demonstrates that the proposed DATCN model outperforms the state-of-the-art baselines. The prediction accuracy of DATCN model after 24 hours reaches 90 percent. Also, the performance in last 14 hours plays a domain role to predict the short-term behaviors of the structure. As a study case, the proposed model is applied in an underwater shield tunnel to predict the stress variation of concrete segments in space.

  • This research was started to study how the design identity of an overseas fashion house was formed, changed and connected. For the purpose of the study, Saint Laurent House was selected as the subject of the study, because it began as a couture house and launched the $pr\hat{e}t-\grave{a}-porter$ for the first time among the designer brands, and also contributed to the development of modern women's fashion. Literature survey on related books and papers was performed to study the Saint Laurent House. Then, fashion collection photos of the house from 1962 SS to 2014 SS were collected to analyze and compare the features of the designs. The photos were collected from related books, fashion magazines and internet sites. The results are as follows: The features of Yves Saint Laurent's early designs were contemporarily sensational with their couture tradition. His representative designs including Le Smoking, Pea Coat, Loose Fit Blouse, Safari Look, Jumpsuit, Ethnic Look and Art Look became the signature looks of the Saint Laurent House. His designs expressed the liberation of sex, multi-cultural sensitivity and the fusion of art and fashion. His successor, chief designer Tom Ford designed with strong sensitivity of his own. He dealt with Yves Saint Laurent's design themes and signature looks in sensual as well as trendy and sophisticated way. Stefano Pilati showed the Parisienne chic and elegance. He re-made the legacies of Yves Saint Laurent with his own design style using new materials or cutting technique. Hedi Slimane reinterpreted the signature looks of the house with his rock' n roll mood for young, modern women while reflecting the spirit of Yves Saint Laurent's early stage. In conclusion, the design identity of Saint Laurent House is not just a fixed one. By the subsequent chief designers, the signature items and design spirit of Yves Saint Laurent have been succeeded, reintroduced or changed to be trendy and to reflect the designers' design sensitivity. All of these make and maintain the design identity of the fashion house.

  • Gianni Versace was a designer who established his unique fashion world by thinking creatively and using rich design sources. The purpose of this study is to present designers a methodology for creative and characteristic design development by searching Gianni Versace's idea source for fashion design. As a method of the study, visual and textual data were investigated for Versace's fashion and design source especially focusing on those elements that inspired him. Versace was born in the southern area of Italy in 1946. Ever since his childhood, he had a lot of experience with clothes because his mother was a dressmaker. His first collection was made in 1978, and Versace became one of the most famous fashion designers in the world within 20 years. He used a wide range of design sources such as history, culture, and art and created his design world with it. He focused on four important epochs. They were classicism, Byzantium, the eighteenth century centering on Baroque, and the 1920s and 1930s centering on Madeleine Vionnet and Madame Gres. Among cultural elements, costume design for ballet and opera and rock 'n' roll music inspired him greatly. Also, Pop art and various paintings such as Chagall's and Delaunay's had a huge effect on Versace. With these elements, he created a bold and unique coordination of style by mixing & matching history, genre, material, and style into his design. Thus he completed an extraordinary and original fashion style by emphasizing on decorative and glamorous points and changing a way of thinking.

The First North Korean Painting in the Collection of the National Museum of Korea: Myogilsang on Diamond Mountain by Seon-u Yeong (국립중앙박물관 소장 산률(山律) 선우영(鮮于英) 필(筆) <금강산 묘길상도>)

  • Myogilsang on Diamond Mountain, signed and dated (2000) by Seon-u Yeong (1946-2009), is the first work by a North Korean artist to enter the collection of the National Museum of Korea (fig. 1a). The donor acquired the painting directly from the artist in Pyeongyang in 2006. In consequence, there are no issues with the painting's authenticity.This painting is the largest among all existing Korean paintings, whether contemporary or from the Joseon Dynasty, to depict this iconography (see chart 1. A Chronological List of Korean Myogilsang Paintings.) It is ink and color on paper, measures 130.2 × 56.2 centimeters, and is in a hanging scroll format. Since this essay is intended as a brief introduction of the painting and not in-depth research into it, I will simply examine the following four areas: 1. Seon-u Yeong's background; 2. The location and the traditional appellation of the rock-cut image known as Myogilsang; 3. The iconography of the image; and 4) A comparative analysis of Seon-u Yeong's painting in light of other paintings on the same theme. Finally, I will present two more of his works to broaden the understanding of Seon-u Yeong as a painter. 1. Seon-u Yeong: According to the donor, who met Seon-u at his workshop in the Cheollima Jejakso (Flying Horse Workshop) three years before the artist's death, he was an individual of few words but displayed a firm commitment to art. His preference for subjects such as Korean landscapes rather than motifs of socialist realism such as revolutionary leaders is demonstrated by the fact that, relative to his North Korean contemporaries, he seems to have produced more paintings of the former. In recent years, Seon-u Yeong has been well publicized in Korea through three special exhibitions (2012 through 2019). He graduated from Pyeongyang College of Fine Arts in 1969 and joined the Central Fine Arts Production Workshop focusing on oil painting. In 1973 he entered the Joseon Painting Production Workshop and began creating traditional Korean paintings in ink and color. His paintings are characterized by intense colors and fine details. The fact that his mother was an accomplished embroidery specialist may have influenced on Seon-u's choice to use intense colors in his paintings. By 1992, he had become a painter representing the Democratic People's Republic of Korea with several titles such as Artist of Merit, People's Artist, and more. About 60 of his paintings have been designated as National Treasures of the DPRK. 2. The Myogilsang rock-cut image is located in the Manpok-dong Valley in the inner Geumgangsan Mountain area. It is a high-relief image about 15 meters tall cut into a niche under 40 meters of a rock cliff. It is the largest of all the rock-cut images of the Goryeo period. This image is often known as "Mahayeon Myogilsang," Mahayeon (Mahayana) being the name of a small temple deep in the Manpokdong Valley (See fig. 3a & 3b). On the right side of the image, there is an intaglio inscription of three Chinese characters by the famous scholar-official and calligrapher Yun Sa-guk (1728-1709) reading "妙吉祥"myogilsang (fig. 4a, 4b). 3. The iconography: "Myogilsang" is another name for the Bhodhisattva Mañjuśrī. The Chinese pronunciation of Myogilsang is "miaojixiang," which is similar in pronunciation to Mañjuśrī. Therefore, we can suggest a 妙吉祥 ↔ Mañjuśrī formula for the translation and transliteration of the term. Even though the image was given a traditional name, the mudra presented by the two hands in the image calls for a closer examination. They show the making of a circle by joining the thumb with the ring finger (fig. 6). If the left land pointed downward, this mudra would conventionally be considered "lower class: lower life," one of the nine mudras of the Amitabha. However, in this image the left hand is placed across its abdomen at an almost 90-degree angle to the right hand (fig. 6). This can be interpreted as a combination of the "fear not" and the "preaching" mudras (see note 10, D. Saunders). I was also advised by the noted Buddhist art specialist Professor Kim Jeong-heui (of Won'gwang University) to presume that this is the "preaching" mudra. Therefore, I have tentatively concluded that this Myogilsang is an image of the Shakyamuni offering the preaching mudra. There is no such combination of hand gestures in any other Goryeo-period images. The closest I could identify is the Beopjusa Rock-cut Buddha (fig. 7) from around the same time. 4. Comparative analysis: As seen in , except for the two contemporary paintings, all others on this chart are in ink or ink and light color. Also, none of them included the fact that the image is under a 40-meter cliff. In addition, the Joseon-period paintings all depicted the rock-cut image as if it were a human figure, using soft brushstrokes and rounded forms. None of these paintings accurately rendered the mudra from the image as did Seon-u. Only his painting depicts the natural setting of the image under the cliff along with a realistic rendering of the image. However, by painting the tall cliff in dark green and by eliminating elements on either side of the rock-cut image, the artist was able to create an almost surreal atmosphere surrounding the image. Herein lies the uniqueness of Seon-u Yeong's version. The left side of Seon-u's 2007 work Mount Geumgang (fig. 8) lives up to his reputation as a painter who depicts forms (rocks in this case) in minute detail, but in the right half of the composition it also shows his skill at presenting a sense of space. In contrast, Wave (fig. 9), a work completed one year before his death, displays his faithfulness to the traditions of ink painting. Even based on only three paintings by Seon-u Yeong, it seems possible to assess his versatility in both traditional ink and color mediums.

  • Micropiles are widely used in construction field to enhance bearing capacity and reduce settlement of existing foundation. It has various benefits such as low construction expense, simple installation process, and small construction equipment. Recently, new microple equipped with the base expansion structure at the end has been developed to improve the foundation bearing capacity. The improvement of load capacity can be conceptually achieved by expanding the base expansion structure when a load is applied to the micropile. However, the expansion mechanism of the base expansion structure and the improvement of load capacity of the micropile were not yet experimentally validated. Therefore, in this study, a series of centrifuge model tests was performed to evaluate the effect of the base expansion structure on the improvement of load capacity. Two types of soil, sand and weathered rock, were prepared and the loading tests were performed using the real micropile with the base expansion structure. During the tests, the earth pressures surrounding the base expansion structure were monitored. As a result, when a load of 30 kN was applied to the micropile, the increase in the ratio of the horizontal to vertical pressure increment (∆σh/∆σ𝜈) ranged from 0.4 to 0.58 in sand and ∆σh/∆σ𝜈 = 0.19 in weathered rock, respectively. Therefore, it can be concluded that the increase in the horizontal earth pressure adjacent to the base expansion structure will improve the bearing capacity of the micropile.
