  • The complete structural characterization of dehydrodivanillin, an important natural product of interest to the food, cosmetics and aroma industries, has been carried out using multi-dimensional NMR spectroscopic techniques, and its previously $reported^{13}$C-NMR values have been reassigned. Dense and granular thin films of dehydrodivanillin have been grown by sublimation under high vacuum and studied using Scanning Electron Microscopy (SEM), electrical and optical techniques. The transmittance spectra of the films indicate a wide optical band gap of more than 3 eV. Typical J-V characteristics of Glass/ITO/dehydrodivanillin/Al structure exhibited moderate current densities ${\sim}10^{-4}\;A/cm^2$ at voltages > 25 V with an appreciable SCLC mobility of the order of $10^{-6}\;cm^2$/V-s.

  • Although brand love is a major interest in global business, very little is known about how the effects of brand love are affected by relevant constructs. This study examines how the brand love-loyalty link is moderated by shopping value (hedonic vs. utilitarian) and how the moderated moderation effect of gender difference influences the consumer-brand relationship. Based on a unique dataset of 254 Chinese consumers of Korean cosmetic brands in China, we tested our proposed hypotheses using Regression PROCESS macro (model = 3). One of our novel findings is that brand love has a positive influence on brand loyalty. However, this relationship is sensitive to moderators. Regarding the brand love-loyalty linkage, consumers who seek hedonic shopping value is higher than consumers who seek utilitarian shopping value. In particular, female consumers are more passionate and loyal than male consumers. Finally, male consumers seeking hedonic shopping value feature greater brand love-loyal linkage than other consumers; however, this effect is very limited.

  • Fructan is a polysaccharide composed of fructose and can be classified into several types, such as inulin, levan, and fructo-oligosaccharides, based on their linkage patterns and degree of polymerization. Owing to its structural and functional diversity, fructan has been used in various fields including prebiotics, foods and beverages, cosmetics, and pharmaceutical applications. With increasing interest in fructans, efficient and straightforward production methods have been explored. Since the 1990s, yeast cells have been employed as producers of recombinant enzymes for enzymatic conversion of fructans including fructosyltransferases derived from various microbes and plants. More recently, yeast cell factories are highlighted as efficient workhorses for fructan production by direct fermentation. In this review, recent advances and strategies for fructan biosynthesis by yeast cell factories are discussed.

  • Collagen은 세포 외에 존재하며, 분자의 수명이 매우 긴 단백질이므로, 노화와 관련된 비효소적 당화의 대상으로 많은 관심이 모아지고 있다. 본 연구에서는 진피 collagen의 비효소적 당화와 분해 및 가교결합에 대한 자외선(UVA)과 활성산소종들의 영향을 검토하였다. 암소 피부로부터 얻은 collagen 과 glucose의 혼합물에 몇가지 활성산소 소거제를 첨가하고 UVA를 조사하여 비효소적 당화, 단백질 분해, 가교결합의 정도를 관찰하였다. 비효소적 당화는 자외선에 의해 증가되지 않았으며, 수퍼옥사이드 라디칼과 일중항 산소의 소거제에 의해서는 감소하였으나, 히드록시 라디칼 소거제에 의해서는 변화가 없었다. 단백질 분해와 가교결합은 자외선에 의해 증가되었으며, 분해는 세가지 활성산소의 소거제 모두에 의해 감소되었으나, 가교결합은 특히 히드록시 라디칼 소거제의 영향이 컸다. 즉 수퍼옥사이드 라디칼과 일중항 산소는 자외선과는 관계 없이 당의 자동산화에 의해 발생되어 당화로 인한 변화의 초기 단게에 관여하고, 반응의 뒷부분에서는 당단백질과 자외선에 의해 만들어진 히드록시 라디칼이 주된 역할을 하고 있다. 상기의 결과로부터 활성산소종들과 자외선은 다른 조직 및 세포물질들을 손상시키듯이 노화와 관련된 collagen 변화를 증가시키는 것을 알 수 있었다. 이는 자외선 차단제와 함께 활성산소 소거 물질들을 외용도포하는 것이 태양광선의 해로운 영향으로부터 진피를 보호하는데 도움이 될 수 있음을 의미한다.

  • Demand for cosmetics with functionality and eco-friendliness has increased dramatically due to recent aging, well-being trends, and increased interest in beauty. Cosmetics production in 2014 was 8,970.4 billion won, an increase of about 50% compared to 6,014.6 billion won in 2010. In the midst of this, similar companies in intense competition are pursuing differentiated strategies and innovation activities to solve quality, price and delivery problems. In particular, cosmetics packaging work is getting more difficult due to the increasing bill of materials (BOM) and difficult assembly methods. Therefore, in this study, the following problems were identified and suggestions for the improvement of the packaging Many research laboratories such as biotechnology, chemistry, and pharmaceuticals, which are undergoing various studies, are equipped with ready-made laboratory safety equipments such as bio-safety workbenches, aseptic bases, and exhaust workbenches. However, most researchers are disadvantaged in using existing safety equipment. This is because existing safety equipment can not take into account all of the unique characteristics of the research. For this reason, researchers are demanding the development of customized safety equipment that is well suited to their research needs. process of Company C, which is facing difficult situation to respond to the customer 's delivery due to the 52 - hour work week. First, we used the stopwatch to find the difficulty process in the packaging process and show ways to improve it. Second, to improve the efficiency of line balancing in the packaging process, we integrate processes, improve work methods, and perform simple automation. As a result, the prepare loss for replacement was reduced by 1 minute from 5 minutes, resulting in a 23% increase in productivity from 112 ea./hour to 137ea./ hour per person. At this time, the LOB of the packaging process was improved from 70% to 82% by operating one more production line through one person per line, total 9 people saving.

  • Amaranth(Amaranthus spp. L.) and quinoa (Chenpodium quinoa Willd.) are old crops from South, Central America and Central Asia and their grains have been identified as very promising food crops because of their exceptional nutritive value. Squalene is an important ingredient in skin cosmetics and computer disc lubricants as well as bioactive materials such as inhibition of fungal and mammalian sterol biosynthesis, antitumor, anticancer, and immunomodulation. Amaranth has a component called squalene (2,6,10,15,19,23-hexamethyl-2,6,10,14,22-tetraco-sahexaene) about 1/300 of the seed and $5\~8\%$ of its seed oil. Oil and squalene content in amaranth seed were different for the species investigated. Squalene content in seed oil also increased by $15.5\%$ due to puffing and from 6.96 to $8.01\%$ by refining and bleaching. Saponin concentrations in quinoa seed ranged 0.01 to $5.6\%$. Saponins are located in the outer layers of quinoa grain. These layers include the perianth, pericarp, a seed coat layer, and a cuticle like structure. Oleanane-type triterpenes saponins are of great interest because of their diverse pharmacological properties, for instance, anti-inflammatory, antibiotic, contraceptive, and cholesterol-lowering effects. It is known that quinoa contains a number of structurally diverse saponins including the aglycones, oleanolic acid, hederagenin, and phytolaccagenic acid, which are new potential in gredient for pharmacological properties. It is likely that these saponin levels will be considerably affected by genetic, agronomic and environmental factors as well as by processing. With the current enhanced public interest in health and nutrition amaranth and quinoa will most likely remain in the immediate future within the realm of exotic health foods until such time as agricultural production meets the quantities and qualify required by industrial food manufacturers.
