The purpose of this study is to analyze the contents of moral textbooks in Chinese elementary school with a multicultural perspective. This can be seen as a plan to prevent conflicts due to migrants in our society. Therefore, the importance of multicultural education in moral education were discussed. And then the contents of Chinese primary moral textbooks(grade 1) was critically analyzed according to content areas. As China was composed of 56 ethnics, the culture of domestic ethnic minority should be understood primarily. As a research result, the educational contents were primarily composed of children's daily lives and social norms which citizens should be abided by. The contents of textbooks do not reflect the feature of china as a typical multi-ethnic society. This can be seen that the Chinese moral education in primary school focuses on social integration. Therefore, we emphasize that the educational contents should be reconstructed with a multicultural perspective. And we hope our research can contribute to recognize and respect the differences between various nations and form a mutually beneficial relationship.

Printing process has been a major sector in the textile industries for a long period of time. With the advent of digital textile printing, the complex procedures of printing preparations and after-treatment processes have been streamlined. For the design of the motives of images to be printed, the use of image handling software, e.g. Photoshop(Adobe), has been of prime importance. Even though the software is extremely useful and functionally versatile, there are many laborious steps involved for the specific textile printing process. The use of a CAD-based textile printing function may help the textile printing process in streamlining the complex processing stages. The image qualities of the output designs have been compared objectively with the aid of several image similarity evaluation schemes including the SSIM, and FSIM Index methods.

This research investigates the influence of chair tilt functionality on biometric signals and user comfort, addressing the ergonomic challenges posed by modern sedentary lifestyles. Through an experimental study involving eight male participants, the impact of chair tilt on electromyography (EMG), heart rate, metabolic rate, pressure distribution, and distance between the lumbar spine and the lumbar support part of the chair was measured across different seating postures. The study utilized chairs with both synchronous and non-synchronous tilt mechanisms to explore how adjustments in chair design affect user comfort and physiological responses during prolonged sitting. Key findings suggest that chair tilt functionality can significantly reduce muscle activity and energy expenditure, enhancing user comfort and potentially mitigating health risks associated with prolonged sedentary behavior. Notably, the study revealed a preference among participants for chairs that aligned the rotational center of the tilt with the hip joint, highlighting the importance of this ergonomic feature in enhancing user comfort. Additionally, the research proposes a novel methodology for assessing seating comfort through the analysis of both biometric and physical signals, providing valuable insights for the development of ergonomic chair designs focused on user health and comfort.

This study aims to express the androgynous image via shirts as a fashion item. Shirts are widely worn as a fashion item regardless of sex and age, with growing importance as a casual outer, with the increase in leisure activities driven by the recent implementation of the 5-Day Work Week system in Korea. As for the theoretical background, the study was reviewed previous studies of books, thesis, a series of publication, and the Internet sites on this topic. Through a careful analysis of these previous studies, it designed and made shirts that inspired by androgynous image. Conclusions of this study are as follows: First, the study found that meanings of symbolism in clothing continue to change, not fixed at all, depending on historic and cultural environments, and so does symbolism for femininity and masculinity of clothing. Second, shirts are widely worn as a fashion item regardless of sex and age, with growing importance as a casual outer, with the increase in leisure activities driven by the recent implementation of the 5-Day Work Week system in Korea. Third, two patters were used for the work in this study in order to emphasize its form, along with mono color white and stripe patterns. For materials, cotton and blend as a most basic material for a shirt were used with unique variations in the form. Fourth, decorative details or trimming such as ribbon tying methods, shirring, attaching in layers, and irregular pleading widely used for women's wear were applied, and silhouettes with strong drape feelings were used to add feminine feature to men' shirts, in an effort to propose a fashion design of the androgynous look. Fifth, clothes proposed in this study are different from feminine clothing item blouse, because they are androgynous shirts mixing masculinity and femininity. Stiff pads were used in collars and cuffs characteristics of men's traditional shirts to maintain masculinity of a shirt, and design was developed by adding feminine decorative elements, which is different from women's blouse.

The genus Dendronephthya, generally known as soft corals, is reported as an abundant and variable taxon. They mostly distribute in warmer waters of the Undo-Pacific Ocean region including Korea. In spite of their abundance and ecological importance as habitats of marine organisms, there are difficulties in the study of their identification and systematics because they have morphological variabilities and limited taxonomec characters. To resolve the problems, we attempted to elucidate the genetic relationships in the genus Dendronephthya by using random amplified polymorphic DNA (RAPD) analysis. This study was based on eight dendronephthian species and one Alcyoniidae species, Alcyonium gracillimum, as an outgroup. The results from all analysis suggest that they could be classified into four groups by the growth form and the anthocodial grades as follows: the first one,D. putteri and D. suensoni with the divaricate form and VI grade; the second one,D. sp.1 and D. sp.2 with the divaricate form and III or IV grade; the third one, D. gigantea and D. aurea being closer than D. spinifera with the glomerate form and III grade; the last one, D. castanea related to D. gigantea rather than D. putteri with the umbellate form and IV grade. Moreover, the divaricate form was separated from the group of the glomerate and umbellate form. At the intraspecies level, the types of the D. castanea, D. gigantea and D. spinifera were separated depending on the feature of spicules in the polyp head, and the coloration could not influence genetic variation. From this study, we can confirm that their morphological characters are compatible with the genetic variation, also RAPD analysis is a very useful method for resolving the systematic relationships of den-deonephthians.
