Today, AI image creation technology is being expanded and utilized across industries. Accordingly, various AI image creation programs optimized for the fashion industry are being developed and commercialized. In this study, we compared and analyzed the visual characteristics of fashion images created by AI image creation programs such as Playground, Midjourney, and The New Black to identify the characteristics of each program and point out areas where each program can be used and problems. The results are as follows: First, while Playground and Midjourney intuitively applied the contents of the command to create images that were different from actual fashion trends, Dannew Black created images that were relatively similar to fashion trends. Second, while Playground separates or combines images corresponding to the command content, Midjourny tends to create new images by adding and fusing various details. Third, in Playground, colors not included in the command appear randomly, and in The New Black, colors not included in the command appear coordinated, and Midjourney generates the color specified in the command relatively accurately. In conclusion, Midjourney can be used when seeking inspiration for developing unique and creative fashion designs, and The New Black can be helpful in referencing fashion trends or fashion styling. On the other hand, playgrounds can be somewhat confusing when it comes to color creation, so this is something to be careful about. It is expected that AI image creation tools can be used more efficiently in fashion design development.

This study compared the production systems and packaging methods as pre- and post-harvest factors for Korean head cabbage, which is minimally processed at the industry locus. It examined how different crop production systems, specifically winter and spring cultivations, affect the characteristics of the Korean head cabbage after harvest. The quality of changes in cabbage characteristics was evaluated over 4 weeks at 10℃. After harvesting, soluble solids content (SSC), hardness, and DPPH (2,2-diphenyl-1-picrylhydrazyl) levels exhibited variations depending on the crop production system, with winter kimchi cabbage maintaining higher levels. These attributes were also influenced by the crop systems and packaging methods. Significant differences were observed in the changes in fresh weight of the Korean head cabbage depending on the packaging method; the extent of these changes was reduced with polypropylene (PP) film packaging. Although the freshness of Korean head cabbage decreased during storage, the appearance was somewhat preserved through film packaging after harvest. The results indicated that the properties of stored Korean head cabbages experienced different effects on pre- and post-harvest quality and characteristics, depending on the measurement items.

Recent Chinese animations emphasize the harmony between content and form, as well as the fusion of reality, emotion, and aesthetic ideals, through character designs that blend traditional cultural elements with modern aesthetic sensibilities. We have observed that this fusion has significantly contributed to the development of the Chinese animation industry. In particular, "Nezha: Birth of the Demon Child" stands out as an important example, where traditional character images are reinterpreted in a modern way, showcasing a unique artistic direction. In this study, we have conducted an in-depth analysis of the major characters in "Nezha: Birth of the Demon Child", focusing on their form, acting, and movement elements based on the theoretical foundation of traditional Chinese aesthetics.We explored how traditional Chinese costumes, totems, and painting styles were utilized in the design of the characters' forms, and discovered that these elements imparted a distinctive artistic quality. Furthermore, we found that the acting and movement elements were influenced by Chinese cultural practices, traditional theater, and martial arts, enriching the characters' motions and expressions. Through this research, we aim to highlight how Chinese animation integrates tradition and modernity, creating new artistic value, and establishing a unique competitive edge in the global animation market.

In light of the development of modern high-tech industries, where human sustainability is becoming increasingly important, anorthosite needs to be reevaluated not only for its potential as a new source of aluminum, but also as a primary resource with a wide range of industrial applications. In particular, a relatively simple chemical composition with a high CaO content and Al₂O₃/SiO₂ ratio, along with its relatively low impurity levels and chemically stable nature offers significant advantages in industrial processes. Thus, anorthosite is considered as an important industrial resource in the age of energy transition. In this review, we examine the mineralogical and geochemical characteristics of anorthosite that determines their stability and reactivity. Based on their characteristics, we propose the potential use of utilizing the anorthosite as an alternative to the Bayer process which has the limitations. We also explore its application as the eco-friendly geo-synthetic materials, and as the new materials for carbon dioxide storage and utilization. As the demand for aluminum applications accelerates, anorthosite is gaining their importance in the geological industry and clean energy field. Therefore, advanced and extensive research on anorthosite complex occurring in the Hadong and Sancheong regions of Korea is critical to obtain opportunities to enhance economic advantages through efficient utilization of national resources and to lead to sustainable development.

This work was carried out to investigate the effect of waterlogging on the growth and nutrient contents of 'Campbell Early' and 'Kyoho' grapevines under the vinyl house condition from June 14 to July 20, 2005. For the trial, seedlings of two-year-old grapevine were transplanted to 40 L pot with a sandy loam soil. Irrigation point of non-waterlogging(control) treatment was controlled at -40 kPa of soil water tension using tensiometer and waterlogging treatments were imposed for 35 days at the water levels of above 10 cm from the soil surface using tap water. The growth of aerial(shoot length, leaf number and stem diameter) and underground(root) parts of 'Campbell Early' and 'Kyoho' grapevines tended to be wholly reduced by waterlogging, while the growth of aerial parts were more severely impaired in 'Kyoho' than in 'Campbell Early' cultivar. The different responses for waterlogging between two grapevines seem to be related with the capacity for absorbing mineral nutrients, because nitrogen content of 'Campbell Early' cultivar leaves was significantly higher than that of 'Kyoho' cultivar although the contents of phosphorus and potassium in leaves of two grapevine cultivars were similarly declined. There was no significant different of fruit quality, such as contents of soluble solid, titratable acidity and weight of berry in 'Campbell Early' between waterlogging and control. In 'Kyoho' cultivar, however, berry weight and titratable acidity were decreased and soluble solid content was increased by waterlogging. It was assumed that waterlogging stress for grapevines promotes maturation and coloring processes of berries by stimulating maturation hormone such as ethylene. In conclusion, 'Campbell Early' cultivar seems to be more tolerable than 'Kyoho' cultivar when comparing the growth responses and nutrient contents between two grapevine cultivars under waterlogging.

This study was conducted to identify the optimum condition for dehydration and storage for maintaining the seed vigor in pelleted carrot seeds. The water content of solid materials of un-pelleted seeds was 4.9% (F.W. basis), and that of pelleted seeds was 24%. When we dehydrated pelleted seeds for 3 hr at $25^{\circ}C$, $35^{\circ}C$, and $45^{\circ}C$, all seeds were dehydrated to 5% - the same level of water content as that before pelleting. Pelleted seeds did not show any significant difference in germination from un-pelleted seeds, and neither was there any significant time or germination difference between pelleted and un-pelleted seeds at the tested dehydration temperatures. However, the $T_{50}$ value of pelleted seeds increased about 3 days larger than that of un-pelleted seeds. Germination speed of pelleted seeds in which the dehydration period was prolonged at $45^{\circ}C$ was delayed compared to those prolonged at $25^{\circ}C$ or $35^{\circ}C$ for the same period. The optimum dehydration condition, which could be applied for large scale in the industry, was dehydration at $35^{\circ}C$ for 3 hr, and the optimum storage temperature which could maintain the seed performance was $5^{\circ}C$.

The effects of drying methods on the browning and moisture sorption characteristics of Rubus coreanus were studied. Fruits were steamed for 5 min at $100^{\circ}C$, dried by sun drying, infrared drying, or freeze drying, and powdered to a size of 20 mesh. Color values were measured and equilibrium moisture contents (EMC) were determined at $20^{\circ}C$, over a range of water activity ($a_w$) from 0.11 to 0.90. The browning indices $L^*$ and $a^*$ values were higher and lower, respectively, in freeze-dried Rubus coreanus compared with other samples. The $b^*$ value was greatest in freeze-dried Rubus coreanus. EMC tended to increase with increasing $a_w$ values, and a particularly sharp increment was observed above 0.75 $a_w$. The EMC of freeze-dried Rubus coreanus was significantly higher compared with the EMC of sun-dried and infrared-dried fruit at constant aw. The moisture sorption isotherms showed a typical sigmoid shape, and the Halsey, Kuhn, and Oswin models were the best fits for the sun-dried, infrared-dried, and freeze-dried powder isotherms, respectively. With respect to monolayer moisture content, the Guggenheim-Anderson-Boer (GAB) equation showed that the various drying methods yielded very different results, with monolayer moisture contents of 0.005 g $H_2O/g$ dry solid in infrared-dried and 0.019 g $H_2O/g$ dry solid in sun- and freeze-dried powders, respectively. These results indicate that the drying method affects the browning and moisture sorption characteristics of Rubus coreanus.
