In the modern fashion industry, the application of different materials along with an emotional design is emerging as an important factor stimulating consumer sentiment. This has led to the diversity of materials and continued active research on materials. Traditional Korean paper is expressed in various ways in the field of visual arts based on Korean sentiment and unique formative characteristics. Hanji costumes have been produced in various ways over the past 20 years utilizing Hanji's physical characteristics, showing unique surface texture and various techniques that differentiate them from existing fabrics, making it symbolic in expanding the area of fashion materials. In this work, various techniques were developed by utilizing the nonwoven characteristics and excellent variability of Hanji while considering visual images, focusing on the delicate decorations and materialistic representations of wedding dresses. In addition, minimal wedding dresses with unique textures were produced to realize fantasy ideas and show surface aesthetics, confirming as a fashion material different from that of existing wedding dresses. The direction of high value-added creation for the industrialization and globalization of Hanji wedding dresses was presented, and the usefulness and scalability of Hanji materials for practical and industrialization were identified in materials that expressed visual art. To in the fashion industry, which is changing in both the wedding industry and the global market, the development of materials with high sensitivity images and original and solid identity should continue.

One of the effective ways to increase data transmission rate is to use massive antenna technique where tens or hundreds of antennas are deployed in base station and spatial diversity gain is improved by multiuser method. If multiuser method is applied, there will be inter-user interference and maximal ratio combiner (MRC) is conventionally used to reduce the complexity of the receiver and to eliminate interference. However, as the number of mobile devices increases, the performance of the conventional receiver becomes deteriorated. To solve this problem, we propose a new detector that completely eliminates the interference from the registered devices and reduces that from the unregistered devices. Then, to reduce the complexity of the proposed scheme, we propose adaptive algorithm of the proposed scheme. Through simulation, we show that the proposed scheme has better bit error rate performance than the conventional scheme.

The purpose of this study is to analyze how modern fashion brands practice cultural sustainability by investigating the ways they use and reinterpret traditional culture and clothing. The transmission and reinterpretation of traditional cultural elements connect the past, present, and future. These forces also lead to the development of new creativity in the fashion industry. Three brands have been selected for case studies: Danha (Korea), Mittan (Japan), and Jan Jan Van Essche (Belgium). These brands possess in-depth understanding of traditional cultural elements, including clothing, dyeing techniques, and patterns unique to various regions and minority groups. The brands all make use of traditional cultural identities whose clothing contains the historical and sentimental values of various regions and ethnic groups. The use and mixing of various cultures can be seen as the respectful preservation of global culture. Also, in contemporary fashion, the use of traditional culture plays an important role in the presentation and development of creative designs. The use of traditional handicraft techniques and the use of traditional clothing in the past convey cultural diversity to future generations; they will have a lasting influence on future fashion trends. The results of the study show that cultural sustainability in contemporary fashion has been implemented through safeguarding and respecting indigenous cultures and developing cultural elements into creative design.

IoT (Internet of Things) devices are being attacked by malware due to many security vulnerabilities, such as the use of weak IDs/passwords and unauthenticated firmware updates. However, due to the diversity of CPU architectures, it is difficult to set up a malware analysis environment and design features. In this paper, we design time series features using the byte sequence of executable files to represent independent features of CPU architectures, and analyze them using recurrent neural networks. The proposed feature is a fixed-length time series pattern extracted from the byte sequence by calculating partial entropy and applying linear interpolation. Temporary changes in the extracted feature are analyzed by RNN and LSTM. In the experiment, the IoT malware detection showed high performance, while low performance was analyzed in the malware family classification. When the entropy patterns for each malware family were compared visually, the Tsunami and Gafgyt families showed similar patterns, resulting in low performance. LSTM is more suitable than RNN for learning temporal changes in the proposed malware features.

Objectives: This study aimed to review the clinical research of the gut microbiome for respiratory diseases to assist the design of trials for respiratory diseases by regulating the gut microbiome with herbal medicine later. Methods: We searched three international databases (PubMed, CENTRAL and EMBASE) to investigate randomized controlled trials (RCTs) of the gut microbiome for respiratory diseases. The selected trials were analyzed by study design, subject diseases, inclusion/exclusion criteria, sample size, study period, intervention group, control group, outcome measures, and study results. Results: A total of 25 studies were included and published from 1994 to 2021 mostly in Europe and Asia. Subject diseases were many in the order of respiratory tract infection, cystic fibrosis, allergy, and so on. As outcome measures, the gut microbiome in a fecal sample was analyzed by 16S rRNA sequencing analysis method, and symptom assessment tools related each disease were used. Major intervention drugs were probiotics and the results were mostly improved in the composition and diversity of the gut microbiome. Conclusion: Clinical studies of the gut microbiome for respiratory diseases have confirmed various effects and this review provides basic data for a well-designed clinical study for respiratory diseases by regulating the gut microbiome with herbal medicine.

Recently, a lot of data has been generated according to the diversity and utilization of information, and the importance of big data analysis to collect, store, process and predict data has increased, and the ability to collect only necessary information is required. More than half of the web space consists of text, and a lot of data is generated through the organic interaction of users. There is a crawling technique as a representative method for collecting text data, but many crawlers are being developed that do not consider web servers or administrators because they focus on methods that can obtain data. In this paper, we design and implement an improved dynamic web crawler that can efficiently fetch data by examining problems that may occur during the crawling process and precautions to be considered. The crawler, which improved the problems of the existing crawler, was designed as a multi-process, and the work time was reduced by 4 times on average.

This paper starts out with a review of the concepts of naturalism and natural clothes. Based on these concepts, the paper aims to create nature-friendly and high-value modem designs by grafting natural images from butterflies into human bodies. The images of butterflies are combined to show distinguished luxury and diversity with natural materials such as denim. As for the design technology, Adove Illustrator 10, Photoshop 7.0, and Prima Vision Textile Design System are used since they are very popular in the CAD system. The followings are the main findings of our research. Naturalism displays its objectivity based on its inherent interest in human nature and its factual description in scientific approaches with an intention to find a true meaning of human life in nature. Natural clothes can be defined as the clothes of natural silhouette which are made of pure materials in natural colors and dyes from natural motifs such as animals, plants or natural phenomena. We have realized that the visually distinguished looks of butterflies are indeed far more luxurious than those of any other insects and this visual distinction can be utilized to attract the attention from designers. Lastly, it turns out that the digital printing technique can create more variety in colors and design forms than the manual printing, thereby providing designers with more options and practicality.

Road design safety assessment by existing tools and methods have normally been examined by expert judgements using design documents and on-site inspections. The existing methods, however, have two main problems such as insufficiency of objectiveness and inability to measure effects of accident countermeasures. This paper studies ways to develop a road safety assessment system through reviewing the IHSDM developed in USA. The crash prediction module of IHSDM calculate accident frequency and rate of roadway segments using accident prediction models and accident modification factors for safety evaluation. The methodology of evaluation and development of accident modification factors somewhat overcome the problems of the existing methods. In spite of these advantages, IHSDM could not relevantly reflect characteristics of domestic rural roadways since it overestimate the number of accidents and rate of korean rural roadways. Especially, IHSDM may not evaluate or consider land use patterns of Korean roadways, and futhermore, original environment on base conditions used to develop IHSDM may not be different from ours. The user requirements being developed for a road safety assessment system for Korean roadways include enhanced flexibility and diversity of data input-output processes.

The interactions of the societal-industrial system with the environment form one of the most critical issues in today's world. The inadequacy of current environmental regulatory structures and of traditional ways of analyzing environmental issues, together with the continuing need to mitigate the environmental perturbations arising from this complex relationship, have led to the development of a new conceptual framework termed industrial ecology. Industrial ecology (IE), defined by Graedel and Allenby, is the means by which humanity can deliberately and rationally approach and maintain a desirable carrying capacity, given continued economic, cultural and technological evolution. The concept requires that an industrial system be viewed not in isolation from its surrounding systems, but in concert with them. IE is a systems view in which one seeks to optimize the total materials cycle from virgin material, to finished material, to component, to product, to obsolete product, and to ultimate disposal. Factors to be optimized include resources, energy, and capital. In the present paper, the concept of Industrial Ecology and its application through efficient and practical Design for Environment (DFE) methodologies and tools will be introduced to Korea. This paper will also emphasis on the industrial environment within which DFE methodologies must be used, including the fundamentals of industrial design activities, concurrent engineering, constraints on design choices and existing technological infrastructure.

Due to the increasing influence of the Korean Wave, traditional themes are emerging to the forefront of performance content development, emphasizing the necessity of applying the art of storytelling to the creative process. The purpose of this research is to examine the differentiated costume design of the Pansori ballet "Dokkaeba! Dokkaeba!," developed through the implementation of storytelling in its performance creation process. Choreographers, writers, and costume designer collaborated throughout the storytelling process from planning to content creation. This resulted in a clarified depiction of the Dokkaebi as divine beings with transcendental powers who are simultaneously friendly and familiar entities, often appearing in the form of humans and objects. Accordingly, the costume design based on this collaborative storytelling deliberately avoided the appearance of Dokkaebi reminiscent of 'Kwimyeonwa' or Japanese 'Oni', typically expressed with horns or decorations, and instead implemented novel design elements, such as fusion Hanbok with a variety of dimensionally aesthetic accessories, meaningful color contrast in modern clothing, textural elements indirectly expressing character and transmogrification, and daily clothing attire to illustrate the humanized Dokkaebi. Therefore, this study seeks to contribute to the production of new performance art showcasing the Dokkaebi by identifying the diversity of expression and direction within costume design.
