        타닌산-아연 복합체를 이용한 단일수준에서의 동물세포 코팅

        이준오(Juno Lee) 한국생물공학회 2017 KSBB Journal Vol.32 No.2

        Coating of individual cells with organic or inorganic materials has drawn a great deal of attention, because it provides the cells with physicochemical durability, which would contribute to the development of bioreactors, biosensor, and lab-on-a-chip, as well as to the fundamental studies in single cell-based biology. Although many strategies have been developed for coating of microbial cells, limited methods are available to coat mammalian cells because most mammalian cells do not have a robust membrane or exoskeleton. Instead, they are enclosed in a lipid bilayer, which is fluidic and vulnerable to changes in its environments. It is more difficult to treat mammalian cells in vitro than microbial cells because the surfaces of mammalian cells are not protected or reinforced by a tough coat. In this work, we report a cytocompatible and degradable nanocoat for mammalian cells. Three types of mammalian cells (HeLa cells, NIH 3T3 fibroblasts, and Jurkat T cells) were individually coated within metal-polyphenol. To maintain the viability of the mammalian cells, we performed the whole processes under strictly physiological culture conditions, and carefully selected nontoxic materials.

        AHP 분석을 통한 인천국제공항 환승객 증대방안에 대한 연구

        전제형,송제환,유수준,이준오,유광의,Jeon, Je-Hyung,Song, Je-Hwan,Yoo, Su-Jun,Lee, Juno,Yoo, Kwang-Eui 한국항공운항학회 2015 한국항공운항학회지 Vol.23 No.2

        This study deals with transfer passengers in hub airports. The research objective is to derive measures for transfer passenger quantity enhancement at Incheon International Airport by applying Analytic Hierarchy Process. In pursuing the above objective, this study conducted a survey to evaluate various selection criteria for choosing transfer airports and ranked attributes in weight order with Analytic Hierarchy Process. Furthermore, based on the trend analysis of Incheon International Airport's transfer passenger movement, this paper analysed main transit routes of Incheon International Airports against competitor airports among the region. The main result found from the study is flight frequency, ticket price and connecting hour were the most important 3 factors when people choose transit airports. Therefore, it is recommended government, airport authority and airlines to cooperate closely to meet the transfer passengers' needs on frequency, price and transit hour of flights.
