The purpose of this study is to analyze and document special design elements of the knit material, such as yarn, stitch, and gauge used in various types of knit in a collection of men's fashion, and to provide basic data for database design. The analysis covers 37 brand collections of men's clothing, used to collect a total of 1,954 men's knitwear photographs, and others were collected from 12 collections from F/W to 2017 S/S collection through www.vogue.com. The results of the analysis of the knit design elements of the contemporary men's collection since 2011 are as follows. First, there were 1,513 straight yarn (77%) and 440 decorative yarn (23%) types of yarn. There were many different kinds of decorative yarn, such as two tone and melange effect in three colors, and the emergence of hairy yarn, like mohair and angora shannell, which was much common in low gauge's knitwear designs. Second, the frequency was high with low and middle gauges. thin and light high-gauges were often found in S/S collections, but there were also thick types of yarn in low-gauge knitwear. Third, 794 (40.6%) items used basic stitches such as plain stitch, which was the most utilized. The plain stitch, which is the most basic of the knit stitches, appears to be in high demand for its use, along with the use of various decorators. The development of printing and dyeing technologies has led to many designs that utilize the printer for the plain stitch. 326 (16.7 %), of colored jacard stitch, and of 175 (0.9 %) of intasia stitch.

The purpose of this study was to study the beauty-coordination characteristics of Genderless fashion, which is emerging as a new trend by analyzing the trend in the latest collection and classify the resulting expression characteristics of make-up. Methods and scope of the study were based on collections published in the 2020 S/S season and 35 out of 84 designers with design elements were selected to analyze the garments most likely to be genderless. The characteristics of the expression of the genderless derived through this analysis were classified into compromise, androgyny, sensuality, exaggeration, enjoyment, and historicity. Compromise was the highest, and the lowest was for enjoyment of the classifications. The designer's work according to the characteristics of each expression shows that the pieces by Saint Laurent were the highest in compromise, sensuality, and historicity, and the pieces by Maison Margiela were the highest in androgyny while Balenciaga was the highest in exaggeration and enjoyment. Compromise represented a mixture of discord, such as incongruous bonding and coloring of heterogeneous materials, and androgyny led to the use of silhouettes and colors, with sensuality utilizing see-through material and incision lines allowing for physical exposure. Exaggeration intentionally destroyed the existing concept by breaking the overall balance of the human body through the enlargement of certain parts of the body, while enjoyment showed unexpectedness by destroying the line and sides of the garment. Lastly, historicity was analyzed for its retro design that transcends time and space with regional cultural and period characteristics.

The purpose of this study is to grasp creation background and social position of courtesan which is treated in social and cultural context and its effect on fashion and research representative courtesans from ancient hetaera to the 19th century and their costume characteristics. Its another purpose is to analyze the costume of Violetta, who is a heroine of opera and its costume characteristic as a courtesan. Most Courtesan clothing were made from bright color, silk and lace which were light, or transparent materials. Using silk and cashmere which were the symbols of class, she took the cutting edge fashion and struggled to break the social barriers. The clothing which the Courtesan wore always became a gossip among people and popular to the designers who could show their creativities because the Courtesan boldly wore the cloth like movie actresses or stars. The Courtesan who led the fashion not only showed the fashion as a simple expression of the beauty but also as a socio-cultural phenomenon which reflected their social awareness with arts, and changed according to the situations of the time and people. Violetta's party dress which was shown in the first and third acts of showed the shoulders and chest because of the deep and wide cut decollete, the waist was tightened with a corset as much as possible, and the opulent hips were inflated by the crinoline so when they walked it was swaying. Also it was decorated with splendid materials such as silk and lace, and sparkling jewels, fans, and neckless and even in case of the general clothing in the second act, it was decorated with braids and lace, frills and ribbons. In the third act, the weakness of the sick woman who was closing her life as the splendid Courtesan was emphasized by using colors of white and light purple and thin transparent materials.

The purpose of this study is to investigate the causes of clothes phenomenon of the ruling class women on the Heian period of Japan in the aspects of politics, economics, society, culture, and religion. The findings of the study are as follows. The main characteristics of the Heian period of Japan may include a rare sense of internationalism, low sense of nationalism, and frequent cases of political intrigue. However, noble culture, centered on royal court, was flourished and it enabled to develop sophisticated and graceful culture. During the Nara period and the Heian period (from $8^{th}$ to $12^{th}$ century), there were enormous changes in the clothes, starting from the mid $10^{th}$ century. The clothes of the ruling class in the Heian period underwent changes from the imitative clothes-imitating the clothes of the Tang age of China- to Japanesque clothes-adding the aesthetic consciousness of Japanese ruling class people. Particularly, the clothes of the ruling class women became massive, majestic, and decorative. The changed clothes had also features such as layered look, utilizing underwear as outer garments, using a wide variety of colors, and using hard and solid materials to make clothes. It can be concluded that the clothes of the ruling class people in the Heian period were affected by plural factors such as national and international political situation, economics, society, culture, and religion. The clothes were used by ruling class people as means of expressing their noble and sophisticated beauty, which led to produce humanistic beauty. The Heian period can be described as an era of the highest reach of humanity.

Light-emitting-diodes (LEDs) are a lighting source useful for the precise evaluation of light quality effect on biological systems. Despite the importance of light spectra on the regeneration of land plant protoplasts ("naked cells"), this factor has not been tested yet on protoplasts from multicellular algae. This study reports on the effects of pure primary colors (red, blue, and green), dichromatic (red plus blue, RB, 1 : 2) and white LEDs on protoplast regeneration from male and female Undaria pinnatifida gametophytes. We also evaluated the effect of different light spectra on pigment composition (chlorophyll a, chlorophyll c, and fucoxanthine), and the light intensities under the best condition on the regeneration process. In the early stages, blue or RB LEDs increased the percentage of dividing female protoplasts, whereas red, blue, and RB LEDs enhanced that of dividing male protoplasts. In the later stages, RB LEDs showed a positive effect only on the percentage of multiple rhizoid-like protrusions (male gametophyte). They also increased the final area of both regenerated gametophytes. The LEDs did not affect pigment composition in female gametophytes. In male gametophytes, in contrast, they reduced chlorophyll c, while blue, RB, and green LEDs decreased fucoxanthin. Under RB LEDs, the optimal light intensity was 80 µmol photons m^-2 s^-1 for female gametophytes and 40 to 60 µmol photons m^-2 s^-1 for male gametophytes. Our results suggest that dichromatic LED illumination (red-blue) improves regeneration of U. pinnatifida gametophyte-isolated protoplasts. Thus, dichromatic LEDs might a suitable light source for enhancing protoplast regeneration in brown seaweeds.

본 연구는 식물공장에서 인공광원에 따른 서로 다른 파장이 'Seneca RZ'와 'Gaugin RZ' 반결구 상추의 광합성 특성, 생육 및 기능성물질 함량에 미치는 영향을 밝히고자 수행하였다. 본 실험에서는 FL(fluorescent lamp), 적색LED와 청색LED 및 백색LED(RBW; red : blue : white = 5 : 4 : 1)와 MH(metalhalide lamp)를 사용하였다. 두 품종 모두 생육 중기에는 RBW에서 광합성속도가 높고 생육 후기에는 'Seneca RZ' 품종은 RBW에서, 'Gaugin RZ' 품종은 MH에서 그 생육이 좋았다. 반결구 상추의 생육은 광원에 따라 생육 차이를 보였으나 각각의 광원의 영향은 품종에 따라 서로 다른 결과를 보였다. 'Seneca RZ' 품종은 생육 중기에는 MH에서, 생육 후기에는 FL에서 생육이 좋았고, 'Caugin RZ' 품종은 생육 중기와 후기 모두 MH에서 생육이 좋은 결과를 보였다. 그러나 수확시기에 'Seneca RZ' 품종은 모든 광원 처리에서, 'Gaugin RZ' 품종은 FL을 제외한 나머지 광원에서 반결구 상추의 잎끝마름증이 발생하는 결과를 보였다. 생육 단계별로 두 품종 모두 생육 중기가 후기에 비해 전반적으로 생육속도가 빠른 결과를 보였다. 'Gaugin RZ' 품종에서 생육 중기에만 광원 종류에 대한 생육속도의 차이를 보였고 생육후기에는 광원의 종류와 품종의 영향을 받지 않는 것으로 나타났다. 인공광원에 따른 두 품종의 반결구 상추의 영양학적 특성은 대부분의 성분에서 광원의 종류에 따른 통계적 유의성이 인정되어 광질이 반결구 상추의 영양학적 품질에 미치는 것으로 판단하였다. 두 품종 모두 RBW에서 4종의 비타민 함량이 높은 결과를 보였으며, 특히 ${\beta}$-Carotene의 함량이 'Gaugin RZ' 품종의 MH에서 가장 높은 결과를 보였다. 이상의 결과에서 인공광원의 종류에 따라 반결구 상추의 생육, 광합성 특성 및 영양학적 품질이 차이가 있으나 품종과 기능성 물질에 따라 각 광원의 영향이 서로 다른 결과를 보여 식물공장 내에서 재배하는 품종과 증진시키고자 하는 기능성 물질에 따라 광원의 선택을 고려해야 할 것으로 판단하였다.
