This study aims to analyze the characteristics of 'Korean Chic' through the collections of Korean designer Eudon Choi, who has gained prominence in the international fashion market. The term 'Korean Chic' encompasses four main traits: coexistence, eclecticism, practicality, and uniqueness. First, coexistence involves blending masculine and feminine elements as well as traditional and modern aspects. This is evident in Choi's use of strong, angular designs typically seen in menswear alongside soft silhouettes and feminine touches found in womenswear. Additionally, traditional Korean hanbok elements are harmoniously integrated with modern design techniques. Second, eclecticism is seen in the balanced mix of direct and subtle expressions, including the fusion of hanbok details with diverse fashion elements, and the combination of monochromatic and vivid colors. This trait also involves blending strong and delicate features to create a dynamic and versatile look. Third, practicality is a cornerstone of Choi's design philosophy. He emphasizes the importance of creating wearable yet innovative pieces that are suitable for daily wear. His collections feature practical materials and items that prioritize comfort without compromising creativity. Last, unique is highlighted through hidden details and unexpected design elements. Choi often incorporates surprising prints or decorations that are not immediately visible, adding an element of discovery and delight for the wearer. This can include witty combinations of traditional and contemporary elements, as well as formal and casual styles. Through study aims to shed light on the design identity of Korean fashion designers by examining the characteristics of Korean Chic in Eudon Choi's work. It also calls for further research on other Korean designers to enhance the understanding and global recognition of Korean fashion's unique aesthetic and growing influence in the international fashion scene.

A grounding system in a large-scale apartment complex consists of a TT grounding system when viewed in each building unit, but the characteristics of TN grounding system appears when viewed in the total ground system function. Therefore, this study examined the characteristics of a grounding system in a large-scale apartment complex using design draft, field measurements and PSCAD/EMTDC modeling. This paper proposes an algorithm for fault analysis depending on the grounding system structure in large-scale apartment complexes considering the connection of the underground culvert as well as a design algorithm for each grounding system considering the contact voltage and step voltage. The simulation results based on the proposed modeling and algorithm confirmed that it is useful for analyzing the characteristics of a grounding system in a large-scale apartment complex.

Gravity wall combined with anchoring frame beam is widely adopted to support a high slope under complex geomorphic condition, in which the rigid gravity wall is adopted as a lower structure and the flexible anchoring frame beam serves as an upper structure. The seismic anchor force and the seismic active earth pressure are two essential issues for the seismic design of combined retaining structure in high seismic intensity area. In this study, an analytical model of combined retaining structure is established based on the upper bound theorem of limit analysis, and the formulas for seismic anchor force and seismic active earth pressure of combined retaining structure are derived. The results are optimized by using the global optimization algorithm. The proposed method is verified by a comparison with previous method. Moreover, the influence of main parameters on seismic anchor force and seismic active earth pressure is analyzed to facilitate the seismic design of such combined retaining structure.

Nowadays, global wedding dress companies are interested in the Chinese wedding market because of expectations in consumption patterns of the post 80's generation. Therefore, wedding behavior, selection criteria for wedding dresses, and favored image by segmented groups targeting 20's to 30's Chinese women were studied to help the Korean wedding dress industry to establish their business in China. The survey was conducted in Shanghai city and three neighboring cities-Wuxi, Zhengziang, and Hangzhou-, and the primary data were analyzed using the SPSS program. As results, Chinese women thought that the wedding ceremony should be elegant and dignified, and they wanted to choose their favorite style rather than a recommended style. The criteria of selection were classified into four factors. Overall image and well fitting with their face and body were the most important factors in the selection of wedding dress. The most favored image was unique/novel image. Several favored images for their wedding dress were significantly different by occasion (ceremony day and photo shoot day) and education level. People of higher education level preferred more luxurious and classic image during the ceremony, and a classic and gorgeous image on the photo shoot day. A white dress and a colored dress for weddings were favored more than the Chinese traditional dress on both occasions. There was also a significant difference between general consumers and the wedding business employees in the quantity of wanted wedding dress.
