In this study, we developed a microfiber-based flexible pressure sensor with high sensitivity and excellent skin breathability. A nonwoven fabric composed of microfibers was prepared by electrospinning, which resulted in excellent moisture permeability of the sensor (143 g∙m^-2∙h^-1). In particular, high-pressure sensitivity (0.36 kPa^-1) was achieved by introducing submicron structures on the microfiber surface by controlling the ambient humidity during electrospinning. The fabrication technology of the microfiber-based flexible pressure sensors reported in this study is expected to contribute to the commercialization of flexible pressure sensors applicable to long-term wearable health monitoring as well as virtual/augmented reality and electronic skin applications.

The facial skin condition expresses physical healthy as well as is considered one of important factors for attractiveness. Especially, most people prefer shiny skin. So various cosmetics has been manufactured for expression of shiny skin. However, shiny skin is subjectively evaluated, and difficult to evaluate clear shininess using the existing method in oily skin. Moreover, there is no clear classification criteria between shininess and glossiness, which is assessed negatively in the skin. So there has not been a reference value by mechanical measurement to define and classify shiny skin from greasy skin. In this study, we measured skin biophysical parameters (gloss, hydration, translucency and sebum) and facial images which are selected by volunteers using sensory evaluation. According to the measurement results, the values of gloss, sebum, and translucency were similar in both shiny and greasy skin; the values of sebum and gloss increased, whereas those of translucency decreased. However only skin moisture values statistically increased in shiny skin. In conclusion, we propose objective assessment criteria for classifying shiny and greasy skin using device measurement and quantitative assessment.

Using Fervidobacterium islandicum AW-1, polar low molecular weight keratin peptides were produced and confirmed through factors related to the skin elasticity. As a result of confirming the cytotoxicity and collagen synthesis ability according to the concentration of the polar low molecular weight keratin peptide in human fibroblasts, it was confirmed that the cytotoxicity did not appear and the collagen synthesis in human fibroblasts was increased. A mask pack containing a polar low-molecular weight keratin peptide was used, and a test product was used for 4 weeks in 22 healthy women subjects. As a result, it showed statistically significant effects on skin elasticity, skin torsion elasticity, skin color and moisture improvement. Through this test, it was confirmed that the polar low-molecular keratin peptide can be used as a cosmetic ingredient that helps improve skin elasticity.

The aim of this study was to evaluate the effect of kimchi powder levels (0, 1, 2, and 3%) and pork skin (5%) on the quality characteristics of liver sausages. The additions of the kimchi powder and pork skin improved the color, cooking yield, and sensory properties of the sausages. The addition of the pork skin and increasing concentrations of the kimchi powder significantly increased cooking yields. The moisture and protein contents of the sausages made with kimchi powder and pork skin were higher than those of the control (p<0.05). Due to the low pH of the kimchi powder, the pH values of the batter and sausages with added kimchi powder were lower than those of the treatment without kimchi powder (p<0.05). The control had the lowest hardness, gumminess, and chewiness values (p<0.05). For the sensory attributes of the samples, color, flavor, juiciness, and overall acceptability were higher in the treatments made with kimchi powder than in the treatments without kimchi powder, in which the treatment with 2% kimchi powder had the highest overall acceptability (p<0.05). In conclusion, the additions of kimchi powder and pork skin improved the quality characteristics of liver sausages.

Ceramides are commonly studied and developed in the cosmetics industry as ingredients that help a moisturized skin and strengthen a skin barrier. In this study, we determined how much great effects the moisturing cream containing a ceramide, obtained from evening primrose oil instead of using a common synthetic ceramide, made on the changes in moisturizing and transdermal water loss of skin. The result showed that the cream with a ceramide showed much better results than the cream without a ceramide at the skin moisture resistance and transdermal water loss of skin.

The moisture absorption rate and structural strength changes of oven-cured composite skin based on closed molds were studied. Moisture absorption was performed on specimens with and without filler applied. The specimens were exposed to moisture for up to 231 days. Tensile and compression tests were conducted with and without filler application. As a result of the test, the moisture absorption rates of the tensile and compressive specimens without filler were 2.4 and 0.3% higher, respectively, than those with the filler applied. The tensile and compressive strengths of the specimen without filler applied were average 305 MPa and 139 MPa, respectively, and the tensile and compressive strengths of the specimen with filler applied were 313 MPa and 166 MPa, respectively, appeared high.

Elasticity and softness of the skin depend on the level of moisture present in the stratum corneum, which is known to be affected by various environmental changes, such as cold and hot winds and dry environments. However, not many studies have been conducted on changes in skin moisture and the degree of recovery due to individual skin differences. In the present study, we aimed to investigate the effect of warm air heating on skin hydration levels and develop moisturizing formulas to improve lowered skin hydration levels. In order to deliver warm air heating condition, heating dryer (40 ℃, 6 m/s, 30 cm apart from forearm) was applied into inner forearm of healthy subjects (male: 10, female: 39, age: 25 - 63) Among 49 subjects, 26 subjects showed significantly lowered skin hydration levels until 30 min after warm air heating exposure (lowered group). In addition, moisturizing cream with high water holding capacity was applied to forearm of 10 subjects in lowered group for 3 weeks and skin hydration levels after warm air heating were significantly improved at the levels of before application of warm air heating. From this study, we found out that there is a skin type that skin hydration levels are significantly decreased under warm air heating condition (dehydrated skin) and this dehydrated skin can be improved by moisturizing formulas with high water holding capacity.

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.
