  • Oxidative stress derived from reactive oxygen species (ROS) is one of the major damaging factors in plants exposed to environmental stress. In order to develop the platform technology to solve the global food and environmental problems in the 21st century, we focus on the understanding of the antioxidative mechanism in plant cells, the development of oxidative stress-inducible antioxidant genes, and the development of transgenic plants with enhanced tolerance to stress. In this report, we describe our recent results on industrial transgenic plants by the gene manipulation of antioxidant enzymes. Transgenic tobacco plants expressing both superoxide dismutase (SOD) and ascorbate peroxidase (APX) in chloroplasts were developed and were evaluated their protection effects against stresses, suggesting that simultaneous overexpression of both SOD and APX in chloroplasts has synergistic effects to overcome the oxidative stress under unfavorable environments. Transgenic tobacco plants expressing a human dehydroascorbate reductase gene in chloroplasts were showed the protection against the oxidative stress in plants. Transgenic cucumber plants expressing high level of SOD in fruits were successfully generated to use the functional cosmetic purpose as a plant bioreactor. In addition, we developed a strong oxidative stress-inducible peroxidase promoter, SWPA2 from sweetpotato (Ipomoea batatas). We anticipate that SWPA2 promoter will be biotechnologically useful for the development of transgenic plants with enhanced tolerance to environmental stress and particularly transgenic cell lines engineered to produce key pharmaceutical proteins.

  • Since the Hwang scandal, the South Korean state has expressed often-conflicting interests of encouraging stem cell research and the IVF industry to save the country and introducing the ethical regulation in conformity with "Global Standard." As the tightening ethical regulation of stem cell research has enervated the field of human Embryonic stem cell(hESC) research, somatic stem cells (re-)emerged as an alternative savior that could rescue the future of research communities, bio-industry, practicing doctors, patients and the nation itself from the crisis. The recent literature on Korean biotechnology, however, mainly focus on hESC and relatively little attention has been given to the rapidly growing field of research on somatic stem cells like hematopoietic stem cells(HSCs) or Adipose derived stem cells(ASCs). While the hESC therapy is often regarded as experimental and ethically controversial, the HSCs or Mesenchymal stem cell(MSC) therapies have already made their ways into people's everyday life through market without much public discussion. Many ordinary people in South Korea are familiar with the story of patients who survived leukemia with the HSCs treatment; the number of doctors who are actively marketing the ASCs therapies is on the rapid increase; the concept of cosmetic products made from ASCs is gaining popularity among consumers. In this context, this article argues that the current ethical debates solely focusing on hESC or on the state policy and research regulation are too limiting to fully illuminate the politics of stem cell technologies in South Korea.

  • For the development of the chitosan industry in Korea, the catch of red snow crabs caught on the east coast is rapidly decreasing. Therefore, it is urgent to develop raw materials that can replace the red snow crab as the top priority to solve the supply and demand problems, as well as wastewater treatment costs account for a large proportion of the cost of chitosan. In order to solve the problems, continuous research on biological extraction methods such as enzymatic extraction and microbial fermentation will increase production efficiency and lower unit cost as well as chemical extraction methods. Further efficient manufacturing method can be established. Establishing of novel techniques is indispensable for production of high-purity chitosan and the ability to regulate and separate the molecular weight, as well as joint research with industry, academia and research institute for the research and development of high-functional chitosan derivatives.

  • Carotenoids are red, orange, and yellow fat-soluble pigments that exist in nature, and are known as physiologically active substances with various functions, such as provitamin A, antioxidant, anti-inflammatory, and anticancer. Because of their physiological activity and color availability, carotenoids are widely used in the food, cosmetics, and aquaculture industries. Currently, most carotenoids used industrially use chemical synthesis because of their low production cost, but natural carotenoids are in the spotlight because of their safety and physiologically active effects. However, the production of carotenoids in plants and animals is limited for economic reasons. Carotenoids produced by bacteria have a good advantage in replacing carotenoids produced by chemical synthesis. Since carotenoids produced from bacteria have limited industrial applications due to low productivity, studies are continuously being conducted to increase the production of carotenoids by bacteria. Studies conducted to increase carotenoid production from bacteria include the activity of enzymes in the bacterial carotenoid biosynthesis pathway, the development of mutant strains using physical and chemical mutagens, increasing carotenoid productivity in strain construction through genetic engineering, carotenoid accumulation through stress induction, fermentation medium composition, culture conditions, co-culture with other strains, etc. The aim of this article was to review studies conducted to increase the productivity of carotenoids from bacteria.

  • Rhapontin is the glycosylated stilbene compound, and comprising major component of rhubarb root extract. Rhapontin has been used as a raw material of skin-whitening cosmetics in Korea. Rhapontigenin, the aglycone of rhapontin, has been suggested to be more active than its glycosylated form. Therefore, the rhubarb root extract was treated with commercial enzyme, Pectinex to remove glycosylated moiety of rhapontin and rhapontigenin was prepared. The resulting material was analysed and identified as rhapontigenin by proton NMR and MALDI-Mass. Rhapontigenin exhibited tyrosinase inhibitory activity with an $IC_{50}$ of $126.72{\mu}g/mL$. The tyrosinase inhibitory activity of rhapontigenin was six times higher than that of rhapontin. In melanin biosynthesis inhibition assay using Streptomyces bikiniensis, rhapontigenin showed wider inhibition zone than that of rhapontin. From these results, we expect that rhapontigenin has stronger skin whitening effect than rhapontin and has advantages in cosmetic industry.

  • The human's basic desire for aesthetics, which has existed along with human history, has been more individualized and diversified according to the progress of modern economic social change. In the case of men, who have a relatively higher connection and experience of mass media compared to women, there is a characteristic to apply and utilize information acquisition and share appearance management quickly on the media. This paper classified and arranged the image and characteristics of the modern male image analyzed the relationship between men's appearance management and information exploration. In addition, exploration relation per information medium was considered by dividing the men's appearance management behavior and characteristics into make-up, hair management, skin care, hands and feet care, and plastic surgery. This appears to be useful for the industrial group, e.g. beauty treatment, cosmetics, hospital, etc. as advertisement marketing information.

  • Silicone-based surfactants consist of a hydrophobic organosilicone group coupled to one or more hydrophilic polar groups, while the hydrophobic groups of hydrocarbon surfactants are hydrocarbons. Silicone surfactants have been widely used in many industrial fields starting from polyurethane foam to construction materials, cosmetics, paints & inks, agrochemicals, etc., because of their low surface tension, lubricity, spreading, water repellency and thermal and chemical stability. A wide range of silicone surfactant structures are required to provide the functional diversity for reflecting the necessities in the various applications. This review covers the basic properties and the synthetic schemes of polydimethylsiloxane and reactive polysiloxanes as hydrophobic siloxane backbones, the main reaction schemes, such as hydrosilylation reaction, for coupling reactive polysiloxanes to hydrophilic groups, and the synthetic schemes of the main polysiloxane surfactants including polyether-, ionic-, carbohydrate-type surfactants.
