  • A customer satisfaction at business activity has influence on affirmative customer reaction. The customer reaction encouragement system(CRES) is to expand the present customer response concept in this paper. The CRES application can make real-time connection between customers and sellers at EC(B2C) environment, and on the basis of this application, it can derive the positive customer reaction encouragement. In this paper, the comparison results between new EC system applied for the CRES and present EC system are proposed.

  • Cleft lip and/or palate are common birth defects in humans and the causes including multiple genetic and environmental factors are complex. Combinations of genetic, biochemical, and embryological approaches in the laboratory mice are used to investigate the molecular mechanisms underlying normal craniofacial development and the congenital craniofacial malformations including cleft lip and/or palate. Both forward and reverse genetic approaches are used. The forward genetic approach involves identification of causative genes and molecular pathways disrupted by uncharacterized mutations that cause craniofacial malformations including cleft lip and/or cleft palate. The reverse genetic approach involves generation and analyses of mice carrying null or conditional mutations using the Cre-loxP mediated gene targeting techniques.

  • The cosmic ray experiment (CRE) on board the KITSAT-1 has been operating normally since the launch of the satellite. CRE is composed of two parts : the cosmic particle experiment (CPE) and the total dose experiment (TDE). Of these, we will discuss on the CPE results obtained the last several months. The data show much larger high energy Particle flux than the Previous UOSAT-3 data. The 550(single event upset) rate is also an order of magnitude higher than the UOSAT-3result. We will compare these results with the Bredictions of the CREME codel. ReferTncesAdams, J. H., Jr., 1987, NRL Memorandun Report 5901

  • In vitro antimicrobial activities of hot water extracts of Camellia sinensis (L.) O. Kuntze, for carbapenem-resistant Enterobacteriaceae (CRE) were compared to commonly used conventional antimicrobial agents. CRE was not only resistant to imipenem, meropenem or ertapenem, but also to various antimicrobial agents, such as amikacin (> $128{\mu}g/mL$). The hot water extracts of Camellia sinensis (L.) O. Kuntze had the lowest MIC ($0.06{\sim}0.5{\mu}L/mL$) of the carbapenem-resistant E. coli, K. pneumoniae, and Enterobacter spp. tested, and it was possible more potent than various conventional antimicrobial agents. Synergistic combinations of the extract with used commonly antimicrobial agents might even improve its antimicrobial chemotherapy property.

  • Geft is a guanine nucleotide exchange factor, which can specifically activate Rho family of small GTPase by catalyzing the exchange of bound GDP for GTP. Geft is highly expressed in the excitable tissue as heart and skeletal muscle and plays important roles in many cellular processes, such as cell proliferation, migration, and cell fate decision. However, the in vivo role of Geft remains unknown. Here, we generated a Geft conditional knockout mouse by flanking exons 5-17 of Geft with loxP sites. Cre-mediated deletion of the Geft gene in heart using Mef2c-Cre transgenic mice resulted in a dramatic decrease of Geft expression. Geft knockout mice develop normally and exhibit no discernable phenotype, suggesting Geft is dispensable for the development of the second heart field in mouse. The Geft conditional knockout mouse will be a valuable genetic tool for uncovering the in vivo roles of Geft during development and in adult homeostasis.

  • We need education program and contents that satisfy on-off line's education maximize an initiative spirit development in an absence of UI design for infants and elementary students. For the multiplicity of inflection of these initiative spirit development education program, we need development of contents and teaching materials(Cre-kids) that can educate both in on-line and in off-line. Cre-kids are divided of four areas that are increased fluency, flexibility, originality and delicacy. Four areas are ideas of language, visual, making and computer. Through each area, we can develop children's systematic modeling idea ability. And we divide of fluency, flexibility, originality and delicacy each four areas and evaluate each aspect and mark for index. That is CDQ(Creativity Design Quotient). Through the evaluation result, we will be able to study about a modeling initiative spirit index.

  • Cyperi Rhizoma (CR), the rhizome of Cyperus rotundus L., exhibits neuroprotective effects in in vitro and in vivo models of neuronal diseases. Nevertheless, no study has aimed at finding the neuroactive constituent(s) of CR. In this study, we identified active compounds in a CR extract (CRE) using bioactivity-guided fractionation. We first compared the anti-oxidative and neuroprotective activities of four fractions and the CRE total extract. Only the ethyl acetate (EA) fraction revealed strong activity, and further isolation from the bioactive EA fraction yielded nine constituents: scirpusin A (1), scirpusin B (2), luteolin (3), 6'-acetyl-3,6-diferuloylsucrose (4), 4',6' diacetyl-3,6-diferuloylsucrose (5), p-coumaric acid (6), ferulic acid (7), pinellic acid (8), and fulgidic acid (9). The activities of constituents 1-9 were assessed in terms of anti-oxidative, neuroprotective, anti-inflammatory, and anti-amyloid-${\beta}$ activities. Constituents 1, 2, and 3 exhibited strong activities; constituents 1 and 2 were characterized for the first time in this study. These results provide evidence for the value of CRE as a source of multi-functional neuroprotectants, and constituents 1 and 2 may represent new candidates for further development in therapeutic use against neurodegenerative diseases.

  • As smart-phones become popular, mobile data traffic has been dramatically increasing and intensive researches on the next-generation mobile communication network is in progress to meet the increasing demand for mobile data traffic. In particular, heterogeneous network (HetNet) is attracting much interest because it can significantly enhance the network capacity by increasing the spatial reuse with macro and small cells. In the HetNet, we have several problems such as load imbalance and interference because of the difference in transmit power between macro and small cells and cell range expansion (CRE) can mitigate the problems. In this paper, we propose a new cell selection scheme with adaptive cell range expansion bias (CREB) for ultra dense HetNet and we analyze the performance of the proposed scheme in terms of average cell transmission rate through system-level simulations and compare it with those of other schemes.
