  • We investigate the change of the Fano effect by considering one Majorana zero mode to couple laterally to the single-dot Fano interferometer. It is found that the Majorana zero mode quenches the Fano effect thoroughly and causes the conductance to be independent of the dot level, the dot-lead coupling, and the increase of the Majorana-dot coupling. As a result, the linear conductance becomes only related to the interlead coupling and the magnetic-flux phase factor. These results can be helpful for the detection of Majorana zero mode.

  • Emotional consumption value orientation has played a significant role to have a direct effect on making purchase in our lives. And emotional value has been dealt within the SPA brand contexts recently. Therefore, the current study investigates how SPA brand consumers' emotional value consumption orientation has affected brand loyalty, with a focus on mediation effects of marketing mix attributes assessment. Results of this research are as follows. First, there was a significant difference between Zara and Uniqlo on the assessment of marketing mix attributes. Second, emotional consumption value orientation had significantly impact on brand loyalty for both Zara and Uniqlo. Third, multi-regression analysis was conducted to find out the mediation effect of marketing mix attributes assessment in the relationships between emotional consumption value orientation and brand loyalty. For Zara, hedonic promotional and pricing attributes of products and place show full mediation effect on brand loyalty. For Uniqlo, utilitarian, hedonic and pricing attributes have impact on brand loyalty. The current study strives to find out how emotional consumption value orientation attected the consumer evaluation process and purchase behavior in the contexts of SPA brand product purchase. Product assessments have stronger effect than place, and hedonic attributes have stronger effect on brand loyalty in comparison with utilitarian attributes. Also, hedonic attributes of product and place have stronger effect on brand loyalty in comparison with utilitarian attributes.

  • Understanding charge trapping at the interface between conjugated semiconductor and polymer dielectric basically gives insight into the development of long-term stable organic field-effect transistors (OFET). Here, the charge transport properties of OFETs using polymer dielectric with various molecular weights (MWs) have been investigated. The conjugated semiconductor, pentacene exhibited morphology and crystallinity, insensitive to MWs of polymethyl methacrylate (PMMA) dielectric. Consequently, transfer curves and field-effect mobilities of as-prepared devices are independent of MWs. Under bias stress in humid environment, however, the drain current decay as well as transfer curve shift are found to increase as the MW of PMMA decreases (MW effect). The charge trapping induced by MW effect is irreversible, that is, the localized charges are difficult to be delocalized. The MW effect is caused by the variation in the density of polymer chain ends in the PMMA: the free volumes at the PMMA chain ends act as charge trap sites, corresponding to drain current decay depending on MWs of PMMA.

  • To consider dynamic magnification effect at the static design stage, impact load factor is applied to design load. Current impact load factor adopted EUROCODE without verification while Japan suggested impact load factor including velocity of high-speed train throughout theoretical and experimental studies. On the purpose of evaluate current impact load factor, this study investigated the calculation of impact load factor from dynamic response of running train.

  • The primary dose effects on an insulated gate bipolar transistor (IGBT) irradiated with a $^{60}Co$ gamma-ray source are found in both of the components of the threshold shifting due to oxide charge trapping in the MOS and the reduction of current gain in the bipolar transistor. In this letter, the IGBT macro-model incorporating irradiation is implemented, and the electrical characteristics are analyzed by SPICE simulation and experiments. In addition, the collector current characteristics as a function of gate emitter voltage, VGE, are compared with the model considering the radiation damage of different doses under positive biases.

  • A hydrogenperoxide sensor containing peroxidase extracted from horseradish was constructed and pH effect on its sensing ability was investigated. Current profiles of the biosensor with pH and the electrophoretic analysis showed that horseradish peroxidase consists of two isozymes. Assuming that it is a hypothetical twoisozyme mixture, the current profiles were deconvoluted into two Gaussians. Application of the new Michaelis-Menten equation connoting pH concept to this system enabled to find all the related dissociation constants of the isozyme-substrates and the isozyme-proton complexes and to determine pHs for the maximal isozyme activities.

  • Much studies have been concentrated to develop the fabrication technique for high critical current density but still there are a lot of gap which should be overcome for large scale application of superconducting materials at liquid nitrogen temperature. The improvement of the critical current can be achieved by forming the nano size defect working as a flux pinning center inside the superconductor. In this paper, the establishment of fabrication condition and additive effects of second elements were examined so as to improve the related properties to the practical use of superconductor.

  • Nanocomposites consisting of a nanocrystalline brass matrix (grain size ; 20-100nm) with sub-micron sized Al2O3 particles (60-200nm) were prepared by pulsed current electrodeposition. The microhardness of the nanocomposite with a grain size of 90-100nm was approximately 1.7 times higher than that of a comparable electrodeposit with no particles. However, significant variations in microhardness were not observed between the nanocomposites with grain sizes of 20 nm and the comparable electrodeposit.

  • To understand the relationship between factors influencing customers' intention to switch from current banking services to mobile banking service. We first investigates immediate influence of customers' satisfaction with existing banking service and attractiveness of mobile banking as an alternative service. We further examines the moderating effect of alternative service attractiveness that influences the relationship between existing service satisfaction and switching intention to mobile banking service.
