The rapid development of the fashion industry in contemporary society has also caused various problems such as environmental pollution, material excess, and spiritual poverty. Accordingly, traditional Chinese Taoist aesthetics can solve the spiritual poverty that people are facing today, and the spiritual pursuit of returning to innocence. This study focuses on the works of first generation Chinese designer Ma Ke as an example to discuss the embodiment and application of Taoist aesthetics. The results are as follows: First, Ma Ke's works emphasize the value of handicraft through traditional handcrafting and natural fibers, which reflect the beauty of simplicity and the non-action of Taoist aesthetics. Second, the works acknowledge nature by using natural materials and retaining their original appearance, which embodies Taoist aesthetics of the beauty in non-action and living in harmony with nature. Third, the collections reflect a critical attitude toward the fashion industry and consumer culture by rethinking consumerism and advocating environmental protection, thus propagating the beauty in simplicity and the harmonious life with nature in Taoism aesthetics. In conclusion, Ma Ke's designs incorporating sustainability and handicraft exhibit the core features of Taoist aesthetics, including the beauty in simplicity, non-action, and living in harmony with nature while exploring the relationship between modernity and tradition, man and nature, and handicraft and fashion. This research can contribute to understanding Ma Ke's works in promoting critical thinking about the fashion industry through Taoist aesthetics.

Recently, interest in natural fabric materials that are not harmful has increased, and hemp is being studied as a new eco-friendly product. This study produced hemp fabric with improved flexibility and increased antibacterial properties by blending it with Hanji yarn. Various weaving methods were proposed to overcome the rough physical properties of hemp, and the functions of the developed products were evaluated through antibacterial tests. The mixing ratios of hemp and Hanji yarns was 50% hemp: 50% Hanji weft, 70% hemp: 30% Hanji weft, 30% hemp: 70% Hanji weft, and 100% hemp. Overall, the higher the ratio of Hanji yarn, the higher the fastness property, and the higher the ratio of hemp yarn, the higher the flexibility of the fabric, which was evaluated to be comfortable to wear. The 99.9% antibacterial properties of hemp products were considered to contribute to maintaining the health of modern people. Owing to its high intensity and high air permeability, it is considered highly usable in the production of children's clothing with a lot of activity. It was evaluated as an advantage that the disadvantage of hemp, which was limited as a material for summer clothing, was broadened to use for all seasons due to the fusion of Hanji. Otherwise, low consumer satisfaction as an outdoor wear is a disadvantage because hemp products had low elasticity and wrinkles.

In the era of globalization, cultural appropriation, stemming from the interaction and clash of diverse cultures, remains inadequately defined, leading to controversy in many designs. This study aims to provide a theoretical basis for understanding cultural appropriation by comparing similar concepts and examining specific cases. It proposes methods for the rational use of traditional cultures in apparel to minimize controversy. Firstly, the study investigates the concept of cultural appropriation by exploring differences among related terms. Secondly, it examines instances of cultural appropriation in fashion through form, color, pattern, and material, drawing from papers and Google searches over the past decade. Thirdly, it categorizes representative cases by domestic and foreign fashion brands, analyzing the underlying reasons. The goal is to establish a theoretical foundation for developing culturally sensitive clothing products. Based on the findings, several measures are proposed: understanding and respecting cultural backgrounds through in-depth research on the history and significance of elements; collaborating with cultural groups and consulting experts for feedback; explaining the source of design inspiration to help consumers understand the cultural elements' meanings; avoiding the reinforcement of stereotypes and respecting cultural diversity and complexity; respecting intellectual property and ensuring moral and legal appropriateness; and learning from case studies of other designers' and brands' successes and failures.

The first esterification reactor in the continuous polymerization of poly(ethylene terephthalate) has been analyzed by solving the material balances for the two-phase system with respect to the solubility of terephthalic acid. The Newton-Raphson method was used to solve the material balance equations instead of the Simplex method that is frequently used for finding a minimum point of a residual rather than a solution of an equation. A solution for the material balance equations, with the constraint of non-zero liquid phase fraction, could not be obtained with the solubility data of Yamada et al., but could be obtained with solubilities over a minimum value that is larger than their data. Thus, the solubility data of Yamada et al. are considered to be too small. On the other hand, the solubility data of Baranova and Kremer are so large that they gave a solution with the liquid phase only. Based on our results, several typical solubility curves satisfying the constraint of a non-zero liquid phase fraction are suggested in this study; we studied the reaction characteristics of the system using these curves. A higher temperature and a lower pressure are preferred for reducing the content of diethylene glycol.
