  • Molecular imprinting, which was first proposed by Wulff and Sarhan in 1972 [1], is a facile way to construct molecular recognition sites by applying a simple radical polymerization [2]. Since 1994, the authors have proposed an alternative molecular imprinting method in which polymeric materials are directly converted into molecular recognition materials [3].(omitted)

  • The demand of micro electrical mechanical system (MEMS) bio/chemical sensor is rapidly increasing. To prevent the contamination of sensing area, a filtration system is required in on-chip total analyzing MEMS bio/chemical sensor. A nano-filter was mainly applied in some application detecting submicron feature size bio/chemical products such as bacteria, fungi and so on. We suggested a simple nano-filter fabrication process based on replication process. The mother pattern was fabricated by holographic lithography and reactive ion etching process, and the replication process was carried out using polymer mold and UV-imprinting process. Finally the nano-filter is obtained after removing the replicated part of metal deposited replica. In this study, as a practical example of the suggested process, a nano-dot array was replicated to fabricate nano-filter fur bacteria sensor application.

  • An imprinting technique with labile covalent interactions has been developed in the design of new polymer catalysts. The template monomer 2 was prepared and copolymerized with DVB or EDMA to provide the polymer with a cavity having the shape of th e transition state of the reaction as well as binding sites for the substrate and catalytic functionalities. The rate of hydrolysis of diphenyl carbonate (1) in the presence of the imprinted polymer IP-DVB-THF was found to be 120 times faster than the background uncatalyzed reaction. A Km of 32 mM and a kcat of 1.8 ${\times}$ 10-3min-1 were observed from Michaelis-Menten kinetics with the imprinted polymer IP-DVB-THF.

  • Characterization of quantitative trait loci (QTL) was investigated in the experimental cross population between Berkshire and Yorkshire breed. A total of 512 F$_2$ offspring from 65 matting of F$_1$ parents were phenotyped the carcass traits included average daily gain (ADG), average backfat thickness (ABF), tenth rip backfat thickness (TRF), loin eye area (LEA), and last rip backfat thickness (LRF). All animals were genotyped for 125 markers across the genome. Marker linkage maps were derived and used in QTL analysis based on line cross least squares regression interval mapping. A decision tree to identify QTL with imprinting effects was developed based on tests against the Mendelian mode of QTL expression. To set the evidence of QTL presence, empirical significance thresholds were derived at chromosome-wise and genome-wise levels using specialized permutation strategies. Significance thresholds derived by the permutation test were validated in the data set based on simulation of a pedigree and data structure similar to the Berkshire-Yorkshire population. Genome scan revealed significant evidences for 13 imprinted QTLs affecting growth and body compositions of which nine were identified to be QTL with paternally expressed inheritance mode. Four of QTLs in the loin eye area (LEA), and tenth rip backfat thickness (TRF), a maternally expressed QTL were found on chromosome 10 and 12. These results support the useful statistical models to analyse the imprinting far the QTLs related carcass trait.

  • Along with the advent of the digital era, the media environment in which an informant would convey information one-sidedly has evolved more towards engaging customers to actively participate and produce contents themselves. This change in content consumption behavior has brought about the new marketing paradigm. The new communication strategy is interactive marketing, which enhances brand-imprinting Effects, and has been consistently proposed these days. This study aims to examine these brand-imprinting effects through an empirical study and to propose an application plan. Therefore, methods of approach for engaging customers' participation and the methods of experiences are categorized by types through the case analysis of various domestic as well as international interactive marketing techniques. In addition, in-depth interviews have been carried out in order to verify the influence of interactive marketing on brand-imprinting effects. Through the interview, potential needs of customers were found. Based on the findings, marketing strategies that utilize interactive media installation for brand-imprinting effects have been constructed. First, to utilize a space for a medium of communication between customers and advertising media. Second, using storytelling as a construct that focuses on the individual's situation. Third, to design interactions that are proper to the situation and context.

  • We have investigated electric field effect on the formation of phase separated composite organic film structure which is utilized by anisotropic phase separation from LC and prepolymer mixtures. Application of bias field resulted in a significant change in liquid crystal alignment between glass substrate and polymer layer. The liquid crystal molecules segregated into the inter-electrodes and formed twisted structure which is the result of imprinting of LC alignment by the bias field on polymer layers during polymerization process.
