Celebrities form a dominant culture of one era and are cultivating influence to lead new fashion. Domestic women celebrities attending Seoul Fashion Week build their image as a fashion leader by exposing their own fashion aesthetics to the public. This promotes PR and sales of the brand of fashion designers in the collection. This study considers the fashion trends of women celebrities by analyzing the fashion style of women celebrities in Seoul Collection over the recent five years. The results of this study on contents analysis are as follows. First, straight silhouettes, achromatic colors, and an absence of a pattern or decoration comprised a high proportion. Celebrities preferred a modern and minimal style. Second, they preferred a feminine style that shows traditional feminine beauty through slim and princess silhouettes, one-piece dress or skirts, soft materials, and decorations with ruffles. In addition, as a matching jacket on one-piece dresses also appeared, it showed that celebrities attempted to change the chic feminine style with masculine beauty. Third, boxy silhouettes, multi-color mixed with colorful colors, graphic or lettering patterns, glittering materials and lots of details comprised a high proportion. This means celebrities pursue a maximal style that reveals their strong presence as fashion leaders.

We investigated the effects of skin hydration and anti-irritation of exopolysaceharide (GF-glucan) produced from submerged culture of Grifola frondosa. The moisturizing effects and trans-epidermal water loss (TEWL) of GF-glucan in cosmetic products (O/W emulsion) were clinically studied. GF-glucan showed good skin hydration effects when compared with sodium hyaluronate which is a commonly using moisturizer. The skin protective effects of GF-glucan against sodium lauryl sulfate (SLS) were also found. Twice a day application of the CF-glucan to skin reduced local inflammation remarkably. Irritant reactions were assessed by various aspects of skin function, erythema (skin color reflectance), hydration (electrical capacitance) and TEWL. In the human skin test, 5-day treatment of the GF-glucan was found to reduce SLS-induced skin erythema and Improve bier regeneration. Taken all together, GF-glucan should be a very useful cosmetic ingredient, as a moisturizer, and a protecting agent for various skin irritations.

A rice bran physically treated to increase the residual gamma amino butyric acid (GABA) content (200 mg/100 g) or its hot-water extract (200 mg/100 g) was added into a white pan bread, and changes in the physical properties including color, and volume and texture changes during storage at room temperature were examined. The addition of bran powders had negative effects on bread quality and storage stability whereas that of rice bran extract (RBE) improved the storage stability of bread. The lightness of bread crumbs decreased but the volume of bread slightly increased after addition of the RBE. The increase in crumb hardness during storage was retarded by the RBE addition. The residual concentration of GABA in bread was increased 38-fold when 20% of RBE was added. The addition of RBE to white pan bread improved the resistance to staling and health-promoting function because of GABA.

'Geumhyang2ho', a new brown and labor-saving variety of Flammulina velutipes, was bred by spontaneous crossing between 'Geumhyang' and 'Garlmoe' during demonstration cultivation in bag culture farm of oyster mushroom in 2013. During bottle cultivation, the temperature was maintained at $16^{\circ}C$; the variety displayed good quality compared to the control ('Geumhyang'), without necessitating vinyl cone treatment. The time periods necessary for mycelial growth, fruit body growth, and primordia formation were 24 days, 11 days, and 8 days, respectively. The total cultivation period was 43 days, which was 2 days longer than that of the control. The pileus diameter was smaller, but the pileus thickness and stipe diameter were greater than those of the control. The pileus color was yellowish ivory, which was very similar to that of the control. The yield of 'Geumhyang2ho' was 118 g per 850 ml bottle, which was markedly lower than that for bottle cultivation with vinyl cone treatment. However, its good quality suggests the potential of the labor-saving bottle-based cultivation of 'Geumhyang2ho' without vinyl cone treatment in oyster mushroom farms.

A strawberry variety 'Arihyang' was derived as an artificial cross between 'Tochiotome' and 'Seolhyang' in 2014. The seedling and line selections were conducted from 2014 to 2015. Preliminary and advanced yield trials of '14-5-5,' which was the final selected line, were conducted from 2015 to 2017. 'Arihyang' is suitable for forced cultivation and has strong plant vigor, uniformly large-sized fruit, and a high yield compared to those of the check variety, 'Seolhyang' and 'Maehyang.' Especially, vitamin C was at a significant level, which was approximately 15% higher than that of 'Seolhyang.' The average number of flowers per first flower cluster was 10.5, which could reduce the labor of thinning fruit. Its fruit has a conical shape, dark red color, and glossy skin. The fruit was of good quality but has recommendations for harvest at the fully ripened stage. 'Arihyang' has intermediate resistant to phytophthora crown rot, but is susceptible to powdery mildew, gray mold, anthracnose, and fusarium wilt. It is reguired to manage major diseases and pests using optimum cultivation techniques and chemical control.

Some flowers have a high sensual appeal owing to their unique shape, color, smell, and taste and have been used as functional food and oriental medicine. Recently, edible dry flowers (EDFs) have attracted social attention as noble sources of functional teas. In this study, for the risk assessment of EDFs, pathogenic bacteria, heavy metals, and pesticide residues were monitored in 23 types of commercial EDF. No Enterobacteria spp. and Listeria spp. were found in all EDF products. However, common aerobic bacteria (3.24~3.85 Log CFU/g) were found in EDF, namely, Pueraria lobata, Chamaemelum nobile, Acacia decurrens, Rhododendron mucronulatum Turcz, Oenothera lamarckiana, Brassica napus, and Prunus serrulata. Staphylococcus aureus was found in 11 and Salmonella sp. was found in 8 of the 23 EDFs. Considering the cold extraction of EDF for tea and beverages, the regulation of pathogenic bacteria in EDFs is necessary. No heavy metals such as Pb, Cd, Co, Cr, Cu, Ni, and As were found in all EDFs, except the dry flower of Hemerocallis fulva, which contained Pb at 0.08 ppm. Different pesticides and fungicides were found in EDFs, but their concentrations were very low (0.01~0.08 ppm) and below the maximal residue level. Only the dry flower of Chrysanthemum morifolium had a high content of chlorpyrifos (0.215 ppm), which is long-lasting pesticide. Our results suggest that the establishment of EDF regulations for pesticide residue, culture separation between edible and garden flowers, and guidelines for preventing pathogenic microbial contamination are necessary.

Flammulina velutipes is the representative edible mushroom in Korea. It makes up around 18% of the total mushroom production and accounts for about 36% of the total mushroom export. Despite being one of the most industrially important mushroom in Korea, the distribution rate of domestic cultivar was low (~31.6%) in 2020. Therefore, we need a new domestic cultivar with high quality as the main export mushroom. We developed a new white domestic cultivar, 'Seolhan', bred by mating two monokaryotic strains isolated from Baekseung and Woori-1ho. The optimum mycelial growth temperature was 25℃ and Seolhan had higher mycelial growth than the control at 20 and 25℃. In bottle cultivation, the optimum temperature of incubation was from 15℃ to 17℃ and the growth temperature of Seolhan was 7-8℃, which was slightly higher than that of the control. The yield of Seolan was 226.5±8.0 g, an increase of 18.4% compared to the control. The period of primodia formation also was a couple of days ahead. In morphological traits, the pileus of Seolhan was smaller than that of the control, the stipe was thicker, and the color brighter. As the results of replacement culture and genetic diversity test, it was confirmed that Seolhan was genetically different from other white varieties.

The effects of punching treatment on mycelial culture and fruiting body productivity were investigated in a new Lentinula edodes cultivar, "Jadam", in sawdust medium for the stable production of oak mushroom. As the punching volume and number increased, the weight loss rate and color difference increased and the L value decreased. After spawn inoculation, the sawdust medium temperature and CO₂ concentration reached their highest values at 33 and 19 days of incubation, respectively. The O₂ concentration showed the lowest value on the 14^th day of incubation, which was the opposite pattern to the CO₂ concentration. As the punching volume and the number increased, the medium temperature and O₂ concentration increased, and the CO₂ concentration decreased. Higher punching volumes and numbers resulted in higher temperatures and lower CO₂ concentrations. The best fruiting body yield was 5 × 70 mm - 30 (punching diameter × depth - number), and the total yield after three cycles was 644.7 g.

The Gymnocalycium mihanovichii has been an important export item of Korean flower industry for a long time. Although there is a high demand for grafted cactus from overseas, its production for export is limited. In this study, the growth and marketable yield characteristics of Gymnocalycium mihanovichii 'I-Hong' were compared between soil culture and ebb-and-flow hydroponic system with single- or double-tier bench. As a result, hydroponic methods with single-tier bench resulted in higher fresh weight and glove diameter compared to other cultivation methods. In the ebb-and-flow hydroponic system, hydroponic system with double-tier bench of grafted cactus traits has a lower growth rate than other cultivations. However, the hydroponic system with double-tier bench of grafted cactus significantly increased the yield. In conclusion, the yield from hydroponic system with double-tier bench was better than soil cultivation method. Although there were some differences in color depending on the cultivation method, it was considered that there was no difference in appearance of Gymnocalycium mihanovichii 'I-Hong'. Our results suggest the cultivation methods to overcome production constraints, expand their exports, and improve the value-added characteristics of grafted cactus.
