Porous materials are useful in a wide range of applications including bio/electronic products. The preparation and processing of these materials are mainly progressed by using an organic solvent, which gives rise to air pollution by its emissions. Alternatively, supercritical fluids are well suited to the production of functional porous materials due to a number of specific physical, chemical, and toxicological advantages. In this review, we will introduce the preparation and processing techniques for the formation of the nano/macro pore structure and their morphology, which can be controled by using supercritical fluids.

A method for coating rice with a novel substance, SHC [soybean hydrolysate with Cyclo Histidine-Proline (CHP)], was developed to produce functional rice for food production. The dip coating and spray coating method was tested to reduce the loss of functionality during the manufacturing of enriched rice. The dip coating method showed a very low absorption rate ($0.079min^{-1}$) of the functional substance compared to control ($0.150min^{-1}$), while the spray-coating method with protective coating materials [a methyl cellulose solution (l%, w/v) containing 5% (w/v) of the SHC] showed relatively adequate absorption characteristics. A light yellowish stain was observed in the rice samples processed by the spray-coating method (b value; surface1 0.69, flour 4.91) compared to raw rice (b value; surface 9.67, flour 4.86). The microscopic appearance of whole kernels and longitudinal sections revealed that cracks formed in all rice samples, regardless of the coating method. In conclusion, spray coating is a potential method for producing SHC-fortified rice with excellent physical characteristics.

This study attempted to categorize the motivation for participation in leisure sports and analyze the difference in consumer demand for leisure sports wear according to the type. As a result of the analysis, the functionality of the preferred material consisted of movement, comfort, and body temperature maintenance. When purchasing, the factors to consider were extracted such as basic emphasis, emphasis on flaunting, and emphasis on practicality. The improvement requirement was composed of basic function improvement and various function additional factors, and the purchase satisfaction factor was composed of three factors: brand, practicality, design, and functionality. Motives for participation in marine leisure sports were grouped into mania, leisure, and health types. As for the functionality of the preferred material, the mania type and leisure type preferred movement, comfort, and body temperature maintenance functionality over the health type. As for the factors to consider when purchasing, the mania type and leisure type had higher consideration for the factors of basic emphasis, ostentation, and practicality than the health type. In the improvement requirements, both basic function improvement and various function additions had the highest mania type and the lowest health type. In terms of purchase satisfaction factors, practicality and brand were found to have a high leisure type, and functional factors were found to have a high mania type. For the enthusiastic group, it is thought that product development should focus on functionality and additional functions, and health types should be focused on design and utilization.

The main objective of this work is to prepare Rehmannia glutinosa extract (RE) incorporated functional chitosan (CH) based biomaterials and evaluate their physical properties, RE release properties, inhibitory effect of melanogenesis, and antioxidant and elastase inhibitory activities. RE incorporated CH based biomaterials were synthesized by a casting method and UV curing process. The surface and cross sections of prepared biomaterials were characterized by a field emission scanning electron microscope (FE-SEM). The physical properties such as tensile strength and elongation at break were also investigated. To apply the transdermal drug delivery system, RE release properties were examined with pH 4.5, 5.5, and 6.5 buffer solutions and artificial skin test at 36.5 ℃. Results indicated that RE release of RE incorporated biomaterials with/without the addition of plasticizers [glycerol (GL) and citric acid (CA)] at pH 6.5 was about 1.10 times higher than that of at pH 4.5. In addition, results of the artificial skin test verified that RE was released constantly for 6 h. To verify the applicability of the prepared biomaterials, tyrosinase, 2,2-diphenyl-1-picrylhydrazyl (DPPH), and elastase assays were investigated. Results indicated that RE incorporated biomaterials added CA exhibited tyrosinase activation, DPPH radical scavenging activity rate, and elastase activation of 45.12, 89.40, and 59.94%, respectively.

The antioxidant and ${\alpha}$-glucosidase inhibition activities of 10 kinds of seaweeds Ecklonia cava (EC), Ecklonia stolonifera (ES), Eisenia bicyclis (EB), Capsosiphon fulvescens (CF), Sargassum fulvellum (SF), Undaria pinnatifida (UP), Sargassum thunbergii (ST), Codium fragile (CFr), Hizikia fusiformis (HF), and Enteromorpha prolifera (EP) were investigated. Among all the tested seaweed extracts, the total polyphenol and flavonoid contents of the EB extract were highest 150.81 mg/g and 77.02 mg/g, respectively. The DPPH and ABTS radical scavenging abilities of the EB ethanol extract (1 mg/mL) were 86.26% and 99.71%, respectively, and its SOD-like activity and reducing power were 21.34% and 1.710 ($OD_{700}$). The ${\alpha}$-glucosidase inhibition activities of the EC, EB, and ST were above 98% at the 0.1 mg/mL concentration. These results suggest that seaweed extracts effectively prevent the what of antioxidants and decrease the blood glucose level, and may be used to develop various functional products.

The aim of this study was to show the antioxidant properties of chestnut (Castanea crenata) bur extracts fermented by Lactobacillus casei. The chestnut has been used as a cosmetic material in Korea for many years. This study showed that reactive oxygen species (ROS) were inhibited by the fermentation materials of chestnut bur extracts. The antioxidant activities were analyzed and expressed as EDA, ABTS, reducing power, SOD-like activity, hydrogen peroxide scavenging activity, superoxide anion radical scavenging activity, and nitric oxide scavenging ability. The antioxidant activities of fermentation materials from L. casei of chestnut bur extracts were higher than those of butylated hydroxyanisole (BHA), epigallocatechin gallate (EGCG), and ascorbic acid (AA). Therefore, we expect that fermentation materials from L. casei of chestnut bur extracts are valuable resources as natural antioxidants and functional cosmetics ingredients.

최근 사회의 다변화, 고령화 및 소비자의 다양한 욕구 증대 등으로 인하여 세분화된 소비계층을 겨냥한 다양한 신제품들이 출시, 판매되고 있는 반면, 일반 백색시유를 제외하고는 제품의 라이프사이클이 크게 줄어드는 경향을 보이고 있다. 건강기능식품 시대의 도래와 함께 첨단 기능성 소재들이 속속 등장하고 있으며, 유가공업계도 이들 소재를 응용한 연구개발과 공정개선을 통한 신제품 출시에 박차를 가하고 있다. 그러나 음용유 시장에서 절대적인 비중을 차지하고 있는 시유부문은 저출산율과 수입개방 등의 악재로 인하여 점차적인 감소 추세에 접어들고 있다. 따라서 국내 유가공업체는 원유소비 증대와 유제품 경쟁력을 확보하기 위해 유제품의 다양화, 고급화를 위한 기술개발 및 유제품의 적극적인 홍보 등의 전략이 필수적이다. 이를 위해서는 종래 단순가공에 의한 유제품 생산에서 탈피하여 새로운 공정 개발, 신물질 탐색 등으로 생산비 절감, 수율 증대, 다양한 형태의 유제품 개발, 그리고 기능성 소재의 탐색 등 건강 지향적 기능성 식품 개발에 노력을 해야 할 것이며 국공립 및 사립대학교 및 정부 출연기관과 일반 유업체의 공동과제 실시 확대로 기능성 식품에 대한인식제고가 필요할 것이다. 또한, TV 매체를 통한 홍보, 우유의 교과서 반영, 자조금 활성화 등으로 어릴 때부터 우유 먹는 습관을 형성하여 시유 소비기반 확대를 도모해야 할 것임과 아울러 교육당국과 협력하여 학생과 영양교사를 대상으로 한 우유에 대한 체계적인 교육프로그램 실시 및 중 ·고등학교 급식화대 추진 등 관련 기관과의 협력체계 구축을 통한 낙농진흥활동을 전개하여야 한다.유아의 창의성수준을 더 높게 평가하였다. 그러나 아버지와 교사간 평가의 상관은 유의하지 않았는데 이는 아버지의 평가수준이 매우 객관적인 것은 아님을 시사한다. 셋째, 창의적인 유아와 일반 유아 아버지 양육태도에서는 유의한 차이를 보였는데 특히 애정-적대요인과 자율-통제요인에서 창의적인 유아와 일반 유아간의 차이가 있는 것으로 나타났다. 넷째, 유아의 창의성과 아버지 양육태도간의 상관관계분석결과 애정적 양육태도와 유창성, 독창성간의 상관이 유의하였다. 집단별 분석시 창의적인 유아를 둔 아버지의 양육태도와 유아의 창의성간에는 상관이 없는 것으로 나타났고, 일반 유아의 아버지 양육태도와 유아의 창의성간의 상관에서는 아버지 양육태도의 성취-비성취 요인에서와 창의성제목의 추상성요인에서 상관이 있는 것으로 나타났다. 따라서 창의성이 높은 아동의 아버지의 양육태도는 일반 유아의 아버지와 보다 더 애정적이며 자율성이 높지만 창의성이 높은 아동의 집단내에서 창의성에 특별한 영향을 더 미치는 아버지의 양육방식은 발견되지 않았다. 반면 일반 유아의 경우 아버지의 성취지향성이 낮을 때 자녀의 창의성을 향상시킬 수 있는 것으로 나타났다. 이상에서 자녀의 창의성을 향상시키는 중요한 양육차원은 애정성이나 비성취지향성으로 나타나고 있어 정서적인 측면의 지원인 것으로 밝혀졌다.징에서 나타나는 AD-SR맥락의 반성적 탐구가 자주 나타났다. 반성적 탐구 척도 두 그룹을 비교 했을 때 CON 상호작용의 특징이 낮게 나타나는 N그룹이 양적으로 그리고 내용적으로 더 의미 있는 반성적 탐구를 했다용을 지원하는 홈페이지를 만들어 자료 제공 사이트에 대한 메타

The antioxidant, whitening, and anti-wrinkle activity of Spirodela polyrhiza extracts and fractions were evaluated to determine its efficacy as a functional cosmetic material. 1,1-diphenyl-2-picrylhydrazyl and 2,2'-azinobis-3-ethylbenzothiazoline-6-sulfonic acid radical scavenging activities were 44.2 and 74.3%, respectively, at 100 ㎍/mL of SE-E (the ethyl acetate fraction of 70% ethanol extract). To measure anti-wrinkle effects, procollagen biosynthesis and matrix metalloproteinase-1 (MMP-1) inhibition activity were determined. At 25 ㎍/mL of SE (70% ethanol extract), the biosynthesis activity was 48.5%, and SE-E showed the best activity (57.8%) at the same concentration. MMP-1 inhibition activity of SE and SE-E was 13.4 and 28.5%, respectively, at 25 ig/mL. Finally, the inhibition of cellular melanin synthesis and cellular tyrosinase were measured to determine the whitening effect; at 25 ㎍/mL, the inhibition activities of SE were 9.6 and 13.8%, respectively, and those for SE-E were 15.4 and 22.0%, respectively. Our results confirmed the possibility of SE and SE-E as effective functional materials. Further research investigating the antimicrobial, anti-inflammatory, and anticancer activities of S. polyrhiza is necessary to confirm its potential use in the food, cosmetics, and drug industries.
