자외선 경화코팅 필름-기질 계면에서의 견딤성에 대하여 조사하였다. 특히, UV 경화 우레탄 아크릴레이트계 배합물에서 모노머 및 올리고머의 코팅필름 주름현상에 미치는 영향은 조사하였다. 실험결과, 주름현상은 DMTA이 손실모듈러스 피크가 넓고 shouldr가 있을수록 덜 나타났다. 특히, 변성된 방향족 우레탄 아크릴레이트를 지방족계에 첨가하므로서 hard하면서도 flexible한 코팅필름을 얻을 수 있음을 알 수 있었다. 따라서 주름현상 방지효과는 높은 손실모듈러스값 때문인 것으로 나타났다. SEM 및 instron 실험결과도 위의 결론을 입증하고 있음을 알 수 있었다.

It has been considered that malic acid, $\alpha$-hydroky succinic acid, could not form crosslinks in the cellulosic materials unless activated by other polycarboxylic acids such as butanetetracarboxylic acid or citric acid because there are only two carboxylic acids per molecule available fur the formation of one anhydride intermediate. However we found that the dicarboxylic malic acid with sodium hypophosphite catalyst without the addition of other crosslinkers was able to improve wrinkle resistance of cotton up to $294^{\circ}$(dry WRA) and $285^{\circ}$ (wet WRA), which is a measure of crosslinking level in cotton. $^1$H FT-NMR, FT-IR and GPC analysis indicated the in-situ formation of an trimeric $\alpha$, $\beta$-rnalic acid with a composition of 1:3 through the esterification between hydroxyl group and one of carboxylic groups in malic acid during curing. The crosslinking of cotton was attributed to the trimeric $\alpha$, $\beta$-malic acid, a tetracarboxylic acid, which can form two anhydride rings during curing. The influence of crosslinking conditions such as concentrations of malic acid and catalyst, pH of the formulation bath, and curing temperature were investigated in terms of imparted wrinkle resistance and whiteness. The addition of reactive polyurethane resin in the formulation slightly increased the mechanical strength retention of crosslinked fabric coupled with additional increase in wrinkle resistance.

Pericarpium castaneae extracts have variously potent activities, such as anti-oxidative activity and free radical scavenging activity. in vivo and in vivo studies both indicate that pericarpium castaneae extracts acts as a flee radical scavenger ($IC_{50}$/: 7.6$\mu\textrm{g}$/ml) stronger than gallic acid($IC_{50}$/: 12.5$\mu\textrm{g}$/ml) and ellagic acid($IC_{50}$/: 15$\mu\textrm{g}$/ml) which could prevent cutaneous UV damages and skin aging. The extracts showed a good effect as a anti-oxidant ($IC_{50}$/: 50$\mu\textrm{g}$/ml). It was shown that the appearance of wrinkle in human skin was reduced by topical application of pericarpium castaneae extracts. And the treatment of human skin with the extracts increased the elasticity and moisture of the skin. We investigated the effect of tile pericarpium castaneae extracts on production of extracellular matrix using cultured A431 fibroblast cells. The results indicated that the extracts had no detectable effect on collagen synthesis, But synthesis of cell adhesion protein was increased by the extracts. The results suggest that increase of cell adhesion protein synthesis by pericarpium castaneae extracts has closely related to reduction of wrinkle in skin.

Anti-melanogenesis and skin anti-wrinkle effects of methanol (ME) and hot water (HE) extracts from the fruiting bodies of Ganoderma applanatum were investigated in this study. The total phenolic contents of the ME and HE of the mushroom were 11.68 and 3.15 ㎍ GAEs/mg, respectively, whereas the total flavonoid contents of the ME and HE were 21.82 and 2.69 ㎍ QEs/mg, respectively. The survival rate of B16-F10 murine melanoma cells treated with 750 ㎍ ME and HE were 83.46% and 85.54%, respectively, thereby suggesting that mushroom extracts were slightly cytotoxic at the tested concentration. The in vitro tyrosinase inhibition by ME (83.15%) and HE (83.44%) was significantly lower than that of kojic acid (99.61%), the positive control, at 2.0 mg/mL. Although the inhibition of cellular melanin synthesis in B16-F10 melanoma cells by 2.0 mg/mL of ME (50.24%) and HE (51.24%) was lower than that of arbutin (64.84%), the inhibition by both ME and HE was higher than 50%. Collagenase inhibition by HE was comparable to 2.0 mg/mL epigallocatechin (EGCG), the positive control; however, elastase inhibition by ME and HE was lower than that of EGCG at the concentration tested. The results showed that the fruiting bodies of G. applanatum had good anti-tyrosinase, good anti-collagenase, and moderate anti-elastase activities, which might be useful for developing novel skin-whitening and anti-wrinkle agents.

Gryllus bimaculatus extract (GbE) have reported that anti-inflammatory activity by suppression of pro-inflammatory cytokines. However, the effects of fermented Gryllus bimaculatus extract (FGbE) have not yet been investigated. In this study, we evaluated the anti-inflammatory and anti-wrinkle effect of the fermented Gryllus bimaculatus extracts using Bacillus subtilis (JB PMB-18) in RAW264.7 cells. Both GbE and FGbE exerted no cytotoxic effects until 1000 ㎍/mL concentration. FGbE decreased NO production and decreased iNOS and COX-2 mRNA levels in a concentration-dependent manner. In addition, the protein production of inflammatory cytokines TNF-α, IL-1β and IL-6 was effectively reduced compared to the GbE. Inhibitory activities of elastase and collagenase associated with skin wrinkle improvement were measured to be 45% and 69%, respectively, at a concentration of 500 ㎍/mL in FGbE. From these results, FGbE can be used as a health functional food and skin functional cosmetic materials for preventing inflammatory diseases because it has excellent anti-inflammatory and anti-wrinkle effects.

Objective : Solar ultraviolet (UV) light can cause photoaging of human skin. Many researchers have focused on effective prevention to mitigate the aging process. This study was aimed to investigate anti-wrinkle effects of pomegranate concentration solution (PCS) using photoaged hairless mouse model. Method : To clarify the protective effect of PCS against UVB-induced photo-damage, water capacity was measured with transepidermal water loss (TEWL) in SKH-1 hairless mice. In addition, image of skin replicas was analyzed. Results : Our results showed that the PCS treatment protects skin against UVB-induced photoaging, based on the parameters including moisture capacity and TEWL. According to visual assessment of skin replica, application of 1 ml/kg PCS inhibited UV-induced wrinkle formation in mice skin as compared to the vehicle-applied control mice. Conclusion : Taken together, these results indicated that PCS could improve skin wrinkle formation induced by UVB irradiation in SHK-1 hairless mice. PCS could be applied as an anti-wrinkle agent.

The purpose of this study is to investigate types and formative characteristics of 'Seon' represented of costume in Amitabha of the late Koryo Dynasty. The results were as follows; The type of 'Seon' is classified into Standard, Decoration and Application types. According to three types, the types of the standard are subdivided into same rotor and no pattern and different color and no pattern, the types of the decoration are subdivided into same color and pattern and different color and pattern, And the types of the application are subdivided into wrinkle and beads-decorated wrinkle according to whether decorative beads exist or not. In the Standard type of Seon, same color and no pattern in the Decoration type of Seon, different color and pattern was most often used as its type while, in the applied type of Seon had its main type of beads-decorated wrinkle. Patterns used for Seon were complex in its composition type and filing in its arrangement style. Seon was used mainly for guneui(裙衣) and daeeui(大衣). The color arrangement of Seon, in most cases, used complementary colors, followed by same ones. Regarding costumes aesthetic characteristics in accordance with the type of Seon, those costumes appeared natural and plain when their Seon was same color and no pattern in type, artificial and plain when their Seon was different color and no pattern in type, natural and brilliant when same color and pattern in type and artificial and brilliant when different color and pattern. In regard to the applied type of Seon, such costumes looked sophisticated and delicate when their Seon was wrinkle in type and dynamic and decorative when beads-decorated wrinkle.
