Create New Online Personal Styling Coordination Model
Zhao Cheng,이성필 한국인더스트리얼디자인학회 2012 산업디자인학연구 Vol.6 No.2
The objective of this research is to study on the existing wardrobe service system and the stylist working condition. In this study, preliminary identification in the system and customers’ dissatisfaction were made, next the framework were created to improve the current condition. Initially, analyzation were made through the existing wardrobe stylist service; and also to it’s work flow and service blue print. The service blueprint divided into four parts, it presents the figure of the service, the service provider and consumer behavior, the specialized service type and the required charge. We again subdivide the service work flow into eight portions. Then, key elements on each of the specialty of the work flow extracted into a questionnaire. Eight random customers who experienced the wardrobe stylist’s service are selected from FGI (FocusGroupInterview)interview section. Finally, through the analysis, the customers were not satisfied with the cloth match and try-on. In fact, the customers are not even satisfied with the service process instead of the service, they are also tired of the whole complex service process. For this reason, the research will investigate the problem in the whole service process and propose the new solution that would transfer the off-line service to on-line services. In this way, it will not only improve the efficiency, but also simplify the complex service process and the framework would be beneficial for the whole industry. In the future continuing research, new on-line service mode will be created based on the current framework, will be positively suitable for wardrobe stylist.

<P>The temporal-spatial structures of plasma flows and turbulence around tearing mode islands are presented. The experiments were performed using Langmuir probe arrays in the edge plasmas of J-TEXT tokamak. The correlation analyses clearly show that the flows have similar structures of <I>m</I>/<I>n</I> = 3/1 as the magnetic island does (<I>m</I> and <I>n</I> are the poloidal and toroidal mode numbers, respectively). The sign of the potential fluctuations for the flows inverses and the powers significantly reduce at <I>q</I> = 3 surface. Approaching to the last closed flux surface for the magnetic islands, the radially elongated flow structure forms. The flows are concentrated near separatrix and show quadrupole structures. The turbulence is concentrated near X-point and partly trapped inside the magnetic islands.</P>

In the thesis, through the analysis and research on the existing models such as Overall Model, Nicosia Model, Engel Mode, Howard-Sheth Model and so on, combining with the elements that influence WeChat apparel shopping behavior and the sorting results draw from KJ method and SPSS, it finds the relationship among Perceived risk, Online retail features, Apparel product quality, Customer satisfaction, Customer loyalty and Customer repurchase intention with the basis of elements in the previous research and creates the customer behavior hypothesis of WeChat apparel shopping platform; then, it makes questionnaire based on hypothesis and 250 questionnaire are sent to customers who have WeChat apparel shopping experience, among 233 received questionnaires, there are 209 effective questionnaire. In order to detect the factor of construct, all the factor values of EFA are bigger than 0.6 and all the reliabilities are bigger than 07; in aspect of statistics, the result is effective. The measurement index of the measurement model in the research is of high fitness and the result of CFA, every measurement value is obviously connected with the corresponding potential factor. So each result of CFA is effective as well in aspect of statistics. From model path coefficients H3 is false and others are true. Among them, H1 is negative correlation and others are positive correlation.

Time-encoded imagers (TEI) are important class of instruments to search for potential radioactive sources to prevent illicit transportation and trafficking of nuclear materials and other radioactive sources. The energy of the radiation cannot be known in advance due to the type and shielding of source is unknown in practice. However, the response function of the time-encoded imagers is related to the energy of neutrons or gamma-rays. An improved image reconstruction method based on MLEM was proposed to correct for the energy induced response difference. In this method, the count vector versus time was first smoothed. Then, the preset response function was adaptively corrected according to the measured counts. Finally, the smoothed count vector and corrected response were used in MLEM to reconstruct the source distribution. A one-dimensional dual-particle time-encode imager was developed and used to verify the improved method through imaging an AmeBe neutron source. The improvement of this method was demonstrated by the image reconstruction results. For gamma-ray and neutron images, the angular resolution improved by 17.2% and 7.0%; the contrast-to-noise ratio improved by 58.7% and 14.9%; the signal-to-noise ratio improved by 36.3% and 11.7%, respectively.

Background: Evidence supporting an association between the 8q24 rs4242382-A polymorphism and prostate cancer (PCa) risk has been reported in North American and Europe populations, though data from Asian populations remain limited. We therefore investigated this association by clinical detection in China, and meta-analysis in Asian, Caucasian and African-American populations. Materials and Methods: Blood samples and clinical information were collected from ethnically Chinese men from Northern China with histologically-confirmed PCa (n=335) and from age-matched normal controls (n=347). The 8q24 (rs4242382) gene polymorphism was genotyped by polymerase chain reaction-high-resolution melting analysis. We initially analyzed the associations between the risk allele and PCa and clinical covariates. A meta-analysis was then performed using genotyping data from a total of 1,793 PCa cases and 1,864 controls from our study and previously published studies in American and European populations, to determine the association between PCa and risk genotype. Results: The incidence of the risk allele was higher in PCa cases than controls (0.222 vs 0.140, $P=7.3{\times}10^{-5}$), suggesting that the 8q24 rs4242382-A polymorphism was associated with PCa risk in Chinese men. The genotypes in subjects were in accordance with a dominant genetic model (ORadj=2.03, 95%CI: 1.42-2.91, $Padj=1.1{\times}10^{-4}$). Presence of the risk allele rs4242382-A at 8q24 was also associated with clinical covariates including age at diagnosis ${\geq}65$ years, prostate specific antigen >10 ng/ml, Gleason score <8, tumor stage and aggressive PCa, compared with the non-risk genotype ($P=4.6{\times}10^{-5}-3.0{\times}10^{-2}$). Meta-analysis confirmed the association between 8q24 rs4242382-A polymorphism and PCa risk (OR=1.62, 95%CI: 1.39-1.88, $P=1.0{\times}10^{-5}$) across Asian, Caucasian and African American populations. Conclusions: The replicated data suggest that the 8q24 rs4242382-A variation might be associated with increased PCa susceptibility in Asian, Caucasian and African American populations. These results imply that this polymorphism may be a useful risk biomarker for PCa in multi-ethnic populations.
Microstructure and Magnetic Properties of Nanocomposite Sm₂Fe15Ga₂Cx / α-Fe Permanent Magnets
Zhao-hua Cheng 한국자기학회 2003 Journal of Magnetics Vol.8 No.1
In our previous work, microstructure and magnetic properties of two-phase exchange-coupled Sm₂Fe_(15)Ga₂Cx/α-Fe nanocomposites have been investigated by means of x-ray diffraction, transmission electron microscopy and magnetization measurement. It was found the exchange coupling between the magnetically hard phase Sm₂Fe_(15)Ga₂Cx and the magnetically soft one α-Fe results in an enhancement of the remanence. The sizes of crystallites of both phases are, however, much larger than the Bloch domain-wall width of the magnetically hard phase. This microstructure gives rise to a concave demagnetization curve and consequently reduces the maximum energy product. In order to improve their magnetic properties, a few percent of Zr, which may be effective to refine the microstructure through rapid quenching, was introduced into the nanocomposites. The addition of Zr was found to improve the magnetic properties significantly. Under optimum heat-treatment conditions, the remanence, coercivity and maximum energy product increase from 0.65 T, 0.48 T and 50 kJ/㎥ for the Zr-free sample to 0.72 T, 0.77 T and 71.6 kJ/㎥ for the 1 at.% Zr-containing one, respectively. The improvements of magnetic properties are due to the refinement of microstructure by the addition of Zr.
