Steel slag, an industrial reject from the steel rolling process, has been identified as one of the suitable, environmentally friendly materials for concrete production. Given that the coarse aggregate portion represents about 70% of concrete constituents, other economic approaches have been found in the use of alternative materials such as steel slag in concrete. Unfortunately, a standard framework for its application is still lacking. Therefore, this study proposed functional model equations for the determination of strength properties (compression and splitting tensile) of steel slag aggregate concrete (SSAC), using gene expression programming (GEP). The study, in the experimental phase, utilized steel slag as a partial replacement of crushed rock, in steps 20%, 40%, 60%, 80%, and 100%, respectively. The predictor variables included in the analysis were cement, sand, granite, steel slag, water/cement ratio, and curing regime (age). For the model development, 60-75% of the dataset was used as the training set, while the remaining data was used for testing the model. Empirical results illustrate that steel aggregate could be used up to 100% replacement of conventional aggregate, while also yielding comparable results as the latter. The GEP-based functional relations were tested statistically. The minimum absolute percentage error (MAPE), and root mean square error (RMSE) for compressive strength are 6.9 and 1.4, and 12.52 and 0.91 for the train and test datasets, respectively. With the consistency of both the training and testing datasets, the model has shown a strong capacity to predict the strength properties of SSAC. The results showed that the proposed model equations are reliably suitable for estimating SSAC strength properties. The GEP-based formula is relatively simple and useful for pre-design applications.

'Beauty(美)' is pursued by many women. It has been expressed through fashion which has become more various as the society became wealthier. This phenomenon can also be found in the Salon Culture of the 17~18th Centuries and in the way that the free-style socialization without specific purposes began by women. Such 'salon culture' fashions have been reproduced in various methods by contemporary fashion designers as they met the trends or as they became the inspiration and source of ideas and were reinterpreted in various styles. Therefore, it is necessary to compare and analyze the studies and expression methods regarding that style's effects on contemporary fashion at a time when the women's salon culture fashion of the 17~18th Centuries is being naturally combined with or restructured to fit in with contemporary fashion. Therefore, the purpose of this study is to analyze, establish the concept of, and summarize the characteristics of the salon fashion style in order to provide fundamental scholarly information and a direction for the fashion design market by establishing a database on the characteristics of both eras based on the characteristics analysis results of the contemporary fashion style and salon culture era. Moreover, this study is also significant in that it will be a helpful tool for new design development to satisfy consumer needs, and in that the comparison analysis on the salon culture and contemporary fashion characteristics can be a useful tool to understand the fashions of both era. The study methods were, first, through a literature review to study the concepts and background of the salon culture. The second method was to setup a style analysis of a period of 4 years and collect visual data from internet fashion information web sites, such as collection books, to collect and analyze the data. Third, the analysis focused mainly on the results of the categorization of images with 20 fashion experts. Fourth, the details of the salon culture fashion style that are used the most in contemporary fashion were summarized and analyzed. Therefore, the results of this study are as follows The development of the socializing culture during the economically abundant era of the 17~18th Centuries became the stepstool for women to enter a new society and at the same time became the background of the development of the salon and related literature. For the characteristics of the salon culture fashion of the 17~18th Centuries, the changes were more significant in the details of the collars, necklines, sleeves, and robes, rather than in partial silhouette changes. It was found that the same fashion repeats in several-century intervals depending on the era changes; however, it has been reinterpreted newly based on consumer preferences and era situations instead of being reused exactly. Therefore, this study will become scholarly and fundamental data to establish the contemporary understanding of the fashion of the salon culture.

The purpose of this study is to expand satirical expressions that appear in a wide range of arts into fashion and to analyse and present satirical expressions that appear in contemporary fashion through the collections of Thom Browne. Theoretical examination of satirical concepts were made of domestic and foreign academic theses, dissertations, precious studies, and publications related to satire. Analysis was conducted on cases in which satirical expressions were applied in literature, painting, sculpture, and fashion. Based on these studies, analysis was conducted on satirical expressions appearing in Thom Browne's work. Material was gathered from collection reviews, interview articles, professional books, and internet photo material from professional fashion magazines encompassing 16 years of Thom Browne's collections officially recorded in the international fashion magazine 'Vogue', ranging from the 2006 S/S collection to the 2021 S/S collection. From this, a total of 1,753 photos were collected as data. Characteristics of satirical expression were analyzed and the results were as follows. A fluid reconstruction of 'gender fluid', dual meanings of metaphorical allegories, playful expressions of visual wit, constructions made of overlapped disassembled material, and borrowing of morphological distortion were all identified. Accordingly, satirical approaches as social aspects and objects in the flow of modern thought appear as positive forms based in humor that hope to be improved. This study anticipate the concept of satire will expand into a positive form as a new direction of fashion.

Hallmarks of clinical behaviors of adenoid cystic carcinoma(ACC) of salivary glands are the delayed onset of vascular metastasis and poor responses to classical chemotherapeutic agents. Poor prognoses from salivary ACC are caused by lung metastases that are resistant to conventional therapy. Therefore, cellular and molecular characteristics that influence the dissemination of metastatic cells are important for the design of more effective treatment of salivary ACC. Tumor angiogenesis has been known to be essential for the distant metastasis of malignant cells. So, we determined expressions of angiogenic proteins in benign (pleomorphic adenoma) and malignant (ACC, mucoepidermoid carcinoma) tumors of salivary glands and compared each other and to those in oral squamous cell carcinoma. Using surgical specimens, we performed immunohistochemical assays with anti-vascular endothelial growth factor (VEGF), VEGF receptor-2 (VEGFR-2), phosphorylated VEGFR-2 (pVEGFR-2), matrix metalloproteinase (MMP)-9, and interleukin (IL)-8 antibodies. Most angiogenic factors were overexpressed in malignant salivary tumors than in pleomorphic adenoma which is benign nature. Moreover, ACC demonstrated more expression of VEGFR-2 than that of squamous cell carcinoma which used as control. Conclusively, these data show those angiogenic factors produced by salivary gland tumors may affect the propagation and metastasis of malignant cells of salivary tumors, and could be used as biomarkers for the malignant transformation of salivary gland tumors. Prospectively, although further studies will be needed, these biomarkers related to angiogenesis can be molecular targets for the therapy of salivary ACC, which has propensity for delayed vascular metastasis.

The purpose of this study is to examine how fine art is received in fashion, and to contribute to the development of a creative fashion culture. In order to do this examination, this study focuses on the formative ideas of De Stijl which appeared in the early 20th century. In addition, this study presents examples of today's fashion that still reflects the formative ideas of De Stijl. The De stijl movement did not last for a long time, but it has had significant influence on modern art, and has been a source of inspiration to fashion designers since the Mondrian look was presented by Yves Saint Laurent in 1965. The study on the basis of De Stijl such as Neo-Plasticism of Piet Mondrian and Elementalism of Theo van Doesburg, has been conducted in this study. As a result, this study presents formative characteristics of the De Stijl group in fashion as follows: First, contemporary fashion designers have searched for proportion and thickness of lines and the side split using lines, a stylistic trait of an artist in the De Stijl group. Second, color scheme defined by the De Stijl group has been applied with modification to contemporary fashion. Modification and selective choice of the limited colors are for a contemporaneous style. Third, formative ideas of De Stijl, which strives to achieve the vision of Utopia, has turned up in contemporary fashion as a simple and minimal silhouette. Contemporary fashion has enhanced their aesthetic value by deriving not only a superficial expression but also plastic principle and philosophy from De stijl. It can be regarded as the fashion's ideal way to embrace style of art and it might be so described as a key to edifying artistic and creative attributes of fashion.

Focusing on the cases applied to korean brand-name apartments In 1960s, economical growth and introduction of western-type cultures led to a boom of apartment construction. After internationalization'in 1980s through Olympic games in 1988, korean culture has attracted attention and individual life quality has been improved. Since 1990s, changes in personal life style has affected the housing culture and the construction companies started moving from quantitative supply to developing their own differential characteristics. Differentiation scheme triggered by construction companies since mid-1990s mainly focused on various ideas for space deployment. Space plans include such things as a private ground, a kitchen in the south, etc. while interior plans include to provide selection of the korean traditional style, natural or casual one. 'korean traditional style' apartment is one of such theme of the brand-named apartment. Interests on 'Tradition' can be broken down into a social trend and media trend. Firstly, the former includes the designation of Bukchon as a reserving area, one of the governmental 'Hanok Survival Program', and traditional building promotion scheme on the basis of construction policy plans. Secondly, the latter covers the interests which attract through the media showing oriental cosmetics, korean culture export via Hallyu, popularity of korean dramas, etc. Thus, it seems worth studying on the apartments with traditional factors. And also, this study aims to setup the concept and trends of korean traditional style apartments through the interior expression on the korean-factor space developed by brand-name apartments so that it could correct such false knowledge out of misunderstood concept of traditional space which results from simple decoration or structure type not accompanying Korean emotion or spirit rendered by some misleading media.

성능 기반 내진설계를 위해서는 지진후 건물의 사용성과 복원성에 대한 명확한 목표가 필요하다. 이를 위해서는 건물의 구성 재료의 검토가 필요하고, 특히, 부재에 잔류하는 변형을 지표로 사용하는 것은 유용하다. 프리스트레스트 콘크리트는 PC 강재의 원점지향적 성질 덕분에 많이 이용이 될 것으로 생각된다. 이 연구는 PSC 보부재의 잔류 변형을 연구하고 산정하는 것에 목표를 두고 있다. '등가 소성 힌지 길이법'을 바탕으로 위험단면에서의 곡률과 등가 소성 힌지 길이를 이용하여 부재의 변형각을 구하는 식을 유도한다. '분할 요소 해석법'을 통하여 PC강재와 콘크리트 사이의 부착-미끄러짐을 고려하면서 힘의 균형과 변형을 적합 조건을 만족하는 해석값을 도출했다. 잔류 변형률에 영향을 미치는 각종 요인들을 파라미터 스터디를 통하여 잔류 변형률 산정식에 필요한 각종 수치를 결정했다. 그중에서 잔류변형에 많은 영향을 미치는 피크시 등가 소성 힌지 길이, 잔류 변형시 등가 소성 힌지 길이 및 피크시부터 잔류 변형시에 발생하는 위험 단면 위치에서의 곡률 감소량에 대하여 중점적으로 검토를 실시했다. 이 연구 결과를 바탕으로 앞으로 활발한 연구가 진행되기를 기대한다.
