Due to the recent surge in popularity of cryptocurrency, the threat of cryptojacking, a malicious code for mining cryptocurrencies, is increasing. In particular, web-based cryptojacking is easy to attack because the victim can mine cryptocurrencies using the victim's PC resources just by accessing the website and simply adding mining scripts. The cryptojacking attack causes poor performance and malfunction. It can also cause hardware failure due to overheating and aging caused by mining. Cryptojacking is difficult for victims to recognize the damage, so research is needed to efficiently detect and block cryptojacking. In this work, we take representative distinct symptoms of cryptojacking as an indicator and propose a new architecture. We utilized the K-Nearst Neighbors(KNN) model, which trained computer performance indicators as behavior-based dynamic analysis techniques. In addition, a K-means model, which trained the frequency of malicious script words for script similarity-based static analysis techniques, was utilized. The KNN model had 99.6% accuracy, and the K-means model had a silhouette coefficient of 0.61 for normal clusters.

A 15-year-old, neutered male, Shih-Tzu, was presented at the Chonnam National Veterinary Medical Teaching Hospital for evaluation of acute onset of persistent coughing, exercise intolerance, and abnormal heart sound. On thoracic auscultation, a split-second heart sound and a wheezing sound were detected on both sides of the chest walls. On physical examination, the dog's body condition score (BCS) was 7/9, and had stenotic nares. Thoracic radiographs revealed right-sided enlargement of the cardiac silhouette (vertebral heart score (VHS) 11.2; reference interval = 8.9-10.1), mild main pulmonary artery (MPA) bulging, mild interstitial infiltration, and hepatomegaly. The electrocardiogram showed right axis deviation, suggesting right ventricular hypertrophy. The echocardiographic study showed moderate pulmonary hypertension and moderate tricuspid regurgitation. There were no findings of a tracheobronchial disease, pulmonary thromboembolism, congenital shunt, left heart disease, or parasitic disease. Based on clinical signs and diagnostic findings, the dog was diagnosed with pulmonary hypertension secondary to brachycephalic syndrome. To rectify respiratory exacerbating factors, the dog was recommended weight control by restricting dietary intake and managing concurrent Cushing's syndrome. Treatments included sildenafil, pimobendan, furosemide, and ramipril. After five months of taking medications and weight control, the severity of pulmonary hypertension improved from moderate to mild. The clinical signs of the patient, including coughing and exercise intolerance, improved a lot. For 5 months of follow-up, the patient has not reported further recurrence of respiratory distress.

This study aimed to examine the appearance of heated clothing in relation to fashion trends by analyzing constructive components of clothing using product images and actual products. A total of 91 images of domestic and foreign heated clothing products were collected, and a product analysis conducted with six parameters of item classification, namely, concept and image, silhouette, color, number of heating elements, and heating parts. In addition, an in-depth analysis was carried out with 11 products among them, while focusing on further detailed components of the design and heating system. As a result, the overall exterior design of domestic products has been changed from outdoor clothing to daily clothing reflecting the current design trend. Compared with domestic products, foreign products showed a diverse assortment and a greater number of heating regions per individual item of clothing. The current heating system commonly consists of a heating element, power source, controller board, and wires, although the existence and type of switches differed from product to product. To develop a more efficiently heated clothing to expand the market, the design, ease of use, safety, consumer preference, heating functionality, and durability should be considered. Along with design recommendations for future heated clothing, this study also provides a practical guide to the technical aspects of the design of the components of heated clothing.

The purpose of this study is to perform research of ecology concepts expressed in fashion and to propose a new ecology fashion design based on the results. As a specific research method, first, to determine the concept of ecology, the contents related to ecology were extracted and organized through literature research, and then a fashion collection research was conducted to acquire basic design data, such as silhouettes, materials, details, and colors. From WGSN, and a total of 57 images were selected and used as basic data for the design suggestions. As a result of collecting the collection images, it was found that cotton or denim fabrics were mainly used, and in particular, the frequency of use was high mainly for bright tones. The use of chambray, lace, and wrinkles, was also frequent, and the use of expression techniques using burn-out, bleach, and bleaching effects or parts, or entire dyeing was often noticeable. The colors showed neutral and pastel-toned characteristics, and the silhouette was mainly composed of long silhouettes centered on maxi, such as a top or calf based on the knee, rather than a mini. Fabrics for the final designs were linen and sappan wood, and they were used for the dye and red was used as the overall color. The silhouettes were simplified, and care was taken to prevent unnecessary waste, such as paper or materials, from being generated during the production stage. We tried to achieve the purpose of eco-logy by refraining from excessive trimming, except for essential subsidiary materials, such as zippers.

Modernism is an internationally accepted design style. In addition, traditional Korean costume is not the clothing of the past, but its form is also used in modern fashion. Therefore, the purpose of this study is to examine the social and cultural contents of the morphological structure of traditional Korean costume, in order to derive the design characteristics of modernism and examine the global applicability of traditional Korean costume structure. For this study, photographic materials from museums, schematic drawings of relics, and Hanbok production books published by government agencies were analyzed. Further, this study examined traditional Korean costume, especially the modernism characteristics derived from Paul Greenhalgh and previous studies. The results are as follows. First, The traditional Korean costume is a cut based on basic shapes, along with a silhouette appears according to the background of the times. Second, the characteristics of modernism can be divided into universality, functionality, and simplicity. Third, as a result of analyzing the form structure of traditional Korean costume based on the characteristics of modernism, universality is expressed as standardized form, functionality as practical aesthetics, and simplicity as sustainable diversity. Furthermore, Korean costume has a difference in that was greatly influenced by various Eastern ideas and aesthetics of the late Joseon Dynasty. These findings provide a perspective of modern reinterpretation of the uniqueness and universality of traditional Korean costume in line with globalization by utilizing the design characteristics of modernism, an international style.

This study aims to use Art brut works-the artwork of the socially underprivileged and alienated-to influence social roles in fashion design, employing a formative expression method to promote social acceptance of diversity in the industry. The research method involved investigating Art brut's concept and evolution in domestic and foreign literature and previous studies. The formative characteristics of the movement were derived by analyzing the works of Art brut artist Johann Hauser. One hundred and twenty images of Johann's work were collected through online sources like the Gugging Museum's website, Christian Berst Gallery's website were developed as fashion design using the CLO 3D program. The formative characteristics of Johann's works appeared to be transparent overlapping, divisional decorativeness emphasized simplicity, and vibrant chromaticity. Based on this analysis, the results of the 3D digital fashion designs were as follows. First, the characteristics of the atypical objects and figures in Johann's works were applied to the design silhouette, revealing a uniquely beautiful form. Second, Johann used a method in which numerous line shapes overlap and fill the area. The point of connecting the work is expressed as a graphic pattern by decorating the lines of the hem and hem of the garment with piping or attaching overlapping straps on top of pants and dresses. Third, the combination of overlapping colors used in Johann's work is a color block design of fashion, which utilizes the formative fun.

This study aimed to facilitate the use of virtual technologies such as sewing, appearance, and material expression in 3D virtual wear programs. For product production and education, we expounded how to express the shoulder shape and silhouette of sleeve-expanded power shoulder jackets. Two designs of sleeve-expanded power shoulder jackets were selected, and virtual jackets were produced using a virtual avatar based on the body dimensions of female subjects in their 20s. The essential purpose of a 3D virtual power shoulder jacket is to express the shoulder angle rise and shoulder width, which are much wider than the avatar's shoulder. Therefore, the virtual pad values were adjusted for the collision and rendering of each thickness. In addition, the position and angle of the virtual pads were controlled through simulation. Appearance similarity was evaluated using photographic data and the virtual jackets. For the set-in sleeve virtual power shoulder jacket, the wrinkle expressions of the torso and sleeve were rated as moderate, and material expression was slightly insufficient. The similarity of some ease and width items of the torso was tightly expressed, and the overall appearance, positions of lines, and details of jackets were rated high, especially at the neck and sleeve shapes. In the case of the kimono virtual power shoulder jacket, the expressions of the torso wrinkles and buttons were slightly lower; however, the overall similarity, basic lines, ease, shoulder and neck details, and material expression of the virtual jackets were highly evaluated.

This study analyzes the characteristics of each element of neo-deconstructivist fashion design and examines fashion expression methods and techniques. This study combines theoretical research and case analysis to analyze the aesthetic characteristics of neo-deconstructivist fashion and the expressive characteristics of neo-deconstructivist fashion. Through analysis of previous research, the aesthetic characteristics of neo-deconstructivism were derived as inclusiveness, playfulness, communication, and intertextuality. Inclusivity in fashion refers to including various people, body types, aesthetics, and cultural backgrounds in the scope of design, and does not limit the scope of clothing design based on individual differences such as body type or gender. Playfulness is a neo-deconstructive fashion brand that combines exaggerated makeup, vibrant colors, intriguing designs, and imaginative fashion shows to spread upbeat and playful ideas. Communication in neo-deconstructivist fashion demonstrates communication through the use of creative themes and items that reflect consumers' needs through design and the consumer's fashion presentation method. Through the mutual quotation of aspects like traits, status, T.P.O., and materials that can reveal opposing texts, intertextuality emerged as a tendency to break up binary oppositions or break away from genres. The expressive qualities of neo-deconstructivist fashion design were examined and applied to the creation of innovative fashion design through examination of the case's silhouette, color, and material. Six sets of women's clothing were designed and produced. The results of this study can be used as basic data for the development of neo-deconstructivist fashion design, and are expected to provide a wide range of inspiration for fashion design ideas.
