As in all Marquis Who's Who biographical volumes, individuals profiled are selected on the basis of current reference value. Factors such as position, noteworthy accomplishments, visibility, and prominence in a field are all taken into account during the selection process.Backed by nearly three decades of practiced experience in his field, Mr. Kwag is now president of Gaya Co., Ltd.In the mid-1980s, he started in the professional world in the department of engineering for Nassau Co., Ltd. After that, he worked for Woongbi Co., Ltd., in the department of instrumentation and at Insan Digichem Co., Ltd., where he developed UV cure acrylic foam tape. Now, he is a president of Gaya Co., ltd and his specialty is producing cold laminating films.Over the years, Mr. Kwag has completed lots of up-to-date training through the Small and Medium Business Corporation in Korea in such areas as the professional technology of adhesive, planning, management, marketing, international trading, and job management. As a president of Gaya, he endeavors to apply professionalism to working environments through innovative technologies. As a result, he has developed various new technologies and was able to register several patents, which are adhesive film with superior adhesive property, detachability and manufacturing methods, and a device for manufacturing pearl coating films which are capable of protecting digital prints. Moreover, he was able to apply for two patents, which are manufacturing methods of hard-coating film with improved curling ability and high-strength. Mr. Kwag is also a member of NTIS (National Science & Technology Service ) where he tries to interact with timely technologies and information.About Marquis Who's Who :Since 1899, when A. N. Marquis printed the First Edition of Who's Who in America , Marquis Who's Who has chronicled the lives of the most accomplished individuals and innovators from every significant field of endeavor, including politics, business, medicine, law, education, art, religion and entertainment. Today, Who's Who in America remains an essential biographical source for thousands of researchers, journalists, librarians and executive search firms around the world. Marquis now publishes many Who's Who titles, including Who's Who in America , Who's Who in the World , Who's Who in American Law , Who's Who in Medicine and Healthcare , Who's Who in Science and Engineering , and Who's Who in Asia .

Anti-inflammatory effects of sulfur-fed duck extract on colitis induced by 2.5% dextran sulfate sodium (DSS) were examined in male Balb/c mice. Animals were divided into eight groups: normal (0.1 mL of PBS without 2.5% DSS), control (0.1 mL of PBS with 2.5% DSS), SD-H (3 mL/kg of high sulfur-fed duck extract), SD-L (1 mL/kg of low sulfur-fed duck extract), GD-H (3 mL/kg of high general duck extract), GD-L (1 mL/kg of low general duck extract), GC-H (3 mL/kg of high general chicken extract), and GC-L (1 mL/kg of low general chicken extract). Mice were fed PBS or six different doses of extracts (sulfur-fed duck, general duck, and chicken), once daily for 14 days. Colitis was induced from day 7 to 14 via the administration of 2.5% DSS in drinking water. The colon length was significantly shortened in mice compared to the control group. The administration of SD-H, SD-L, and GD-L increased colon length and decreased histological colon injury from DSS-induced colitis. However, chicken extracts did not recover any clinical sign of the colitis. SD-L significantly suppressed not only the concentrations of IL-1β, IL-6, TNF-α, IL-17A, and IL-12 in serum but also the mRNA expressions of IL-6, TNF-α, iNOS and COX-2 in DSS-treated colon tissues (P<0.05). The administration of SD-H suppressed the concentrations of IL-6 in serum and the mRNA expressions of IL-6, iNOS, and COX-2 in colon tissues. Administration of GD-L suppressed the concentrations of IL-6, TNF-α, and IL-17A in serum and the mRNA expressions of IL-6, iNOS, and COX-2 in colon tissues. The inhibitory effects of sulfur-fed duck extracts were effective at a dose of 1 mL/kg. Our results indicate that sulfur-fed duck extracts may possess anti-inflammatory effects on DSS-induced colitis mice.

In vitro anticancer effects of black soybean doenjang on HT-29 human colon cancer cells were studied. SD (soybean doenjang prepared with nine-time baked bamboo salt) and BD (black soybean doenjang prepared with nine-time baked bamboo salt) were compared with CD (commercial doenjang). There were no significant differences between experimental groups in terms of pH, amino-type nitrogen, and ammonia-type nitrogen levels of the doenjang samples. BD showed the highest antioxidative effect, followed by SD and CD in that order. BD also showed the highest total polyphenol concentration of all samples. CD, SD, and BD extracts showed no toxic effects on normal RAW 264.7 cells at a concentration ranging from 0.1 to 0.5 mg/mL. BD exhibited anticancer effect on HT-29 cells by MTT assay. Also, BD manipulated mRNA expressions in certain factors; it suppressed pro-inflammatory cytokines such as TNF-α, IL-6, and COX-2, promoted cell-cycle-related genes of p21, and p53, suppressed expression of cyclin D1, and suppressed anti-apoptotic Bcl-2; such manipulation by BD was the strongest, followed by SD and CD in order. From the results above, BD exhibited the highest anticancer effects by inhibiting growth of HT-29 cells, probably by regulating pro-inflammatory cytokines, cell cycling related genes, etc. These results might be due to using black soybeans containing high levels of polyphenol, including anthocyanins. © 2015, Korean Society of Food Science and Nutrition.
