The purpose of this study was to investigate the effects of power blog self- presentation and on-line shopping mall reviews on the word of mouth (WOM) effect and apparel purchasing behavior. Consumers living in Seoul and Gyeonggi received questionnaires. There were 303 usable forms that could be analyzed by descriptive statistics, factor analysis, Cronbach`s alpha, and regression analysis. The results were as follows: There was a significant effect of power blog self-presentation such as interactivity, media effect, and business intention on information acceptance through WOM. Power blog self-presentation, such as interactivity and business intention, affect information delivery by WOM significantly. There was a significant effect of review consideration, such as agreement, usefulness, enjoyment, and purity, on information acceptance of WOM. Reviews describing enjoyment, purity, and usefulness affect information delivery of WOM significantly. Business intention, media effect, and purity directly affect apparel-purchasing behavior, and affect the WOM effect as a mediator variable and then purchasing behavior. Whereas, interactivity, overstatement, and enjoyment affect the WOM effect as a mediator variable, and then affect overall purchasing behavior. Therefore, fashion firms consider active interaction with power blog visitors and promote the way of enjoying with fun through review of apparel on-line shopping mall when they try to implement viral marketing with WOM effect.
A new model for the prediction of the steepness profile across the strip in flat rolling
Jinseok Kim,Sangmoo Hwang 한국소성가공학회 2010 기타자료 Vol.2010 No.6
In flat rolling, wavy surfaces are easily formed in the strip, causing the problem of poor flatness. The wavy surfaces may not only reduce the commercial value of the product but also lead to the breakage of the strip while passing through the roll gap. Therefore, it is necessary to strictly control the wave formation. In this paper, we present a new approach to the prediction of the wavy shape of the strip. The approach is based on minimization of the potential energy and adopts Ritz method as a solution technique. The approach is described in detail, with emphasis on the procedure to treat the effect of the total tension on the shape of the formed waves. The prediction accuracy of the proposed model is examined through comparison with predictions from the finite element method. Then, demonstrated is the model’s capability of reproducing various wavy surfaces that may be observed in the flat rolling mill.

<P>The capacitance-voltage (<I>C</I>-<I>V</I>) characteristics with and without light illumination were evaluated for a capacitor with a Pt gate on the atomic-layer-deposited HfO<SUB>2</SUB> dielectric. The flat-band voltage (<I>V</I><SUB>fb</SUB>) is conventionally determined by a <I>C</I>-<I>V</I> curve. However, the extracted values of <I>V</I><SUB>fb</SUB> were dependent on the <I>C</I>-<I>V</I> sweep direction and the starting voltage of the sweep (<I>V</I><SUB>start</SUB>). The increasing differences between <I>V</I><SUB>start</SUB> and intrinsic <I>V</I><SUB>fb</SUB> (<I>V</I><SUB>fb,i</SUB>) results in the increasing deviations of <I>V</I><SUB>fb</SUB> from <I>V</I><SUB>fb,i</SUB>. Therefore, the value of <I>V</I><SUB>start</SUB> should be close to <I>V</I><SUB>fb,i</SUB> and different values of <I>V</I><SUB>start</SUB> must be applied to the devices with significantly different <I>V</I><SUB>fb,i</SUB>.</P>

<P>Influenza A virus has evolved and thrived in human populations. Since the 1918 influenza A pandemic, human H1N1 viruses had acquired additional N-linked glycosylation (NLG) sites within the globular head region of hemagglutinin (HA) until the NLG-free HA head pattern of the 1918 H1N1 virus was renewed with the swine-derived 2009 pandemic H1N1 virus. Moreover, the HA of the 2009 H1N1 virus appeared to be antigenically related to that of the 1918 H1N1 virus. Hence, it is possible that descendants of the 2009 H1N1 virus might recapitulate the acquisition of HA head glycosylation sites through their evolutionary drift as a means to evade preexisting immunity. We evaluate here the evolution signature of glycosylations found in the globular head region of H1 HA in order to determine their impact in the virulence and transmission of H1N1 viruses. We identified a polymorphism at HA residue 147 associated with the acquisition of glycosylation at residues 144 and 172. By <I>in vitro</I> and <I>in vivo</I> analyses using mutant viruses, we also found that the polymorphism at HA residue 147 compensated for the loss of replication, virulence, and transmissibility associated with the presence of the N-linked glycans. Our findings suggest that the polymorphism in H1 HA at position 147 modulates viral fitness by buffering the constraints caused by N-linked glycans and provide insights into the evolution dynamics of influenza viruses with implications in vaccine immunogenicity.</P>
