This study examined the trend and aesthetic value of image fashion of the 21st century through empirical case study with image media as fashion communication tool. This research is intended to provide the basic material for both better comprehension of image fashion as emotional medium in the modern fashion and more activated research on interactivity and communication in the fashion communication area by examining how fashion designers deliver their design philosophy, thought and vision via image fashion. For the research method, the theoretical study was realized about image media and fashion communication with focus on related literature and precedent research. Also, the empirical study was performed about image fashion covering 2005 through 2012 by the group of fashion film, fashion animation, and video look-book. Fashion image in the research was developed into various layouts that include the story based or non-story based creative images, many kinds of episode or behind-the-scenes story in the prep course of collection, designer's personal life or product world, or re-cutting course after collection. It also played a communicative role for public relation of new product ad, concept conveyance of seasonal collections, means as online collection to substitute for the existing offline collections, and better understandings of designer or fashion brand. Aesthetic values derived from case analysis of image fashion in the modern fashion of 21st century appeared in the form of trans-boundary as convergence art, fantasy in harmony with virtuality and reality, and interactivity among the humans, image media and fashions.

Flower buds of the mulberry(Morus alba L., Morus bombycis Koidz.) were cultured under different conditions such as basal media, and various concentrations of plant growth substances. Effects of the culture conditions on growth of the buds and organ regeneration were investigated and the result obtained are as follows: Murashige and Skoog(M.S.) medium was more effective on budding and growth of female(Keomseolppong) and male(Kaeryangppong) flower buds isolated directly from branches, compared to Greshoff & Doy(G.D.) and Wolter & Skog(W.S.) media. The growth of the female buds was promoted at higher concetration of benzyl amino purine(BAP) i.e., 2.0ppm. The female and male buds cultured after cuuting for seven days showed better growth than those without cutting treatment. The females and the males bloomed to form healthy stigmas and anthers, respectively, when cultured on M.S. media containing high Kinetin with low concentration of indole acetic acid(IAA).

Recently, Google MedeiaPipe presents a novel approach for neural network-based hair segmentation from a single camera input specifically designed for real-time, mobile application. Though neural network related to hair segmentation is relatively small size, it produces a high-quality hair segmentation mask that is well suited for AR effects such as a realistic hair recoloring. However, it has undesirable segmentation effects according to hair styles or in case of containing noises and holes. In this study, the energy function of the test image is constructed according to the estimated prior distributions of hair location and hair color likelihood function. It is further optimized according to graph cuts algorithm and initial hair region is obtained. Finally, clustering algorithm and image post-processing techniques are applied to the initial hair region so that the final hair region can be segmented precisely. The proposed method is applied to MediaPipe hair segmentation pipeline.

The expansion of the performing arts market to include new genres of art that combine art and cutting-edge media technology has surpassed the limitations of traditional theatre art elements such as stage, costumes, lighting, sound, and props, allowing free expression of space-time and visual art. It is growing into a wide area with unlimited potential in the performing arts sector. In response to these changes and the demands of the time, there is an increasing demand for multi-talents who can plan and produce arts and technology-converged contents that will contribute to the development of the performing arts industry. As a result, university departments related to theatre art across the country feel that it is urgent to develop curricula that will enhance students' competency by incorporating the latest media technologies such as virtual reality, holography, and interactive motion sensors into the existing performance art visualization process. In this study, the author will examine the process of developing courses in technology-incorporated theatre art (design) through case studies of media technology-converged performances from the past 10 years. Based on the traditional concept of theatre art, the attempt to fuse stage art with media technology will be a cornerstone of attempts to foster a group of talented artists who transcend the limits of creative visual expression and creative value.

Four experiments were conducted to determine growth regulators, their concentrations and treatment time, rooting medium, and plant parts for optimum seedling propagation by stem cuttings in yacon (Polymnia sonchifolia Poepp. & Endl.). NAA was the most effective on rooting, and followed by IBA 2,4-D, and IAA. Dipping the base of cuttings in 50 or 100 ppm solutions of IBA increased rooting ratios. The 100 ppm solution of IBA was 14% higher than the 50 ppm solution for rooting ratios. Rooting medium with equal volumes of clay loam and sand was the most suitable for rooting of cuttings. Cuttings with both terminal bud and the first node or cuttings with both the first and second nodes were higher in rooting ratios than cuttings with only terminal bud or the first or second nodes. Days to rooting was not affected by plant parts.

The reaction-sintered alumina and zirconia-alumina ceramics having low firing shrinkage were prepared from the Al/Al2O3 or Al/ZrO2(Ca-PSZ) powder mixtures via the attrition milling. And in this milling process the effect of the characteristics of used powders was investigated. Attrition milling was much more effective in reducing the particle size of ceramic/metal mixed powders than ball milling. Powder mixtures of flake-type Al with coarse alumina was much more effectively comminuted by the attrition milling than the mixtures of globular-type Al with coarse alumina powders. And coarse alumina than fine alumina was much more beneficial in cutting and reducing the ductile Al particles. In the contrary to Al/Al2O3 powder mixtures, Al/ZrO2 powder mixtures was not effectively comminutd. But whether using the alumina ball media or attrition milled with Al2O3 powder rather than Al, the milling efficiency was much more increased.

Vibrational film has been more employed in ear-phones or small type of speakers along with a wide use of portable multi-media equipments such as MP3 and MP4. However, the current hand work production process of diaphragms is inefficient. In this study, a die-and-mold and a single production forming machine are developed, and they result in a multi-production forming machine. The multi-production forming machine consists primarily of a film feeding unit and an unwinding unit. A vacuum suction device provides the film feeding unit, while the unwinding unit is obtained using an appropriate damper. The advantage of the developed single production forming machine is shown according to a proper voice test.
