Original articles, topical reviews, pictorial essays, and notable case reports are published in Ultrasonography covering state-of-the-art content. Ultrasonography also serves as a medium for cooperation among physicians and specialists from around the world who are focusing on various ultrasound technology and disease problems.
Different atomic spectrometric methods were applied for arsenic (As) speciation in foods, such as high performance liquid chromatography (HPLC) coupled with inductively coupled plasma mass spectrometry (ICP‐MS). In this study, the analytical method to determine arsenic speciation; the inorganic arsenic species As(III), As(V) and the organic species arsenobetaine (AsB), dimethyl arsinate (DMA) and monomethyl arsenate (MMA) were determined in foods by HPLC‐ICP/MS method. For liquid chromatographic separations we used a PerkinElmer Series 200 HPLC with an isocratic pump, auto‐sampler and C18 column. The mobile phase consisted of a solution containing 1.5 mM malonic acid and 1.5 mM 1‐octanesulfonic acid in water. The ion lenses of the ICP‐MS (ELAN DRC‐e, PerkinElmer) were optimized to achieve the highest signal/background ratio for the isotope 75As. The calibration curve showed linearity in the range between 0.998~0.999. Limits of quantification in As(III), As(V), AsB, DMA and MMA were measured 2.58, 0.08, 0.43, and 0.01 ug/kg, respectively. Intra‐day for As(III), As(V), AsB, DMA and MMA were 111, 91, 94, and 98%, and inter‐day were 111, 91, 94, and 98%, respectively. As(III) and AsB were below the determination limits (<DL) in laver samples studied. The toxic inorganic arsenic species: As(V) was 0.19 mg/kg and organic arsenic species: DMA and MMA were 0.21~0.65 mg/kg and 0.06 mg/kg, respectively.
Chromium poisoning phenomena were compared among three SOFC cathodes consisting of La 0.8 Sr 0.2 MnO 3 (LSM), La 0.6 Sr 0.4 Fe 0.8 Co 0.2 O 3 (LSCF) and LaNi 0.6 Fe 0.4 O 3 (LNF) under relatively large cathode polarization conditions. Deposition of chromium near the cathode/electrolyte interface seems to be affected only by the cathode polarization, not by the cathode materials nor the current density.
The purpose of this paper is to develop and test a conceptual model of purchase intentions, positive emotion, and e-servicescape that is defined as the online environment factors that exist during service delivery. Survey research method was used to gather data regarding consumers' perceptions of e-servicescape. Surveys were administered to 681 college students who experienced purchasing fashion products on the Internet. The results showed that e-servicescapes perceived by fashion consumers were composed of three dimensions: (1) Aesthetic appeal, (2) Ambient conditions, and (3) Layout & functionality. These dimensions of e-servicescape influenced consumers to lead positive emotions and purchase intentions. Additionally, positive emotions constituted a key variable for the purchase intention of fashion products during online exchange. The study revealed that consumers' interpretations of online environments exerted a powerful influence over positive emotion and purchase intentions. Also, it strongly endorsed the view that the purchase intentions of customers were linked to the extent to which they feel positive emotions by the e-service provider. This study provides insights into how consumers' interpretations of e-servicescape affect their subsequent positive emotions and ultimately their intentions to purchase. The findings of this study also have numerous implications for both services managers and internet developers related to fashion products.
The purposes of this study were to examine whether the e-promotion interest was an influencing variable on promotion-acceptance attitudes, browsing, consumer satisfaction and e-loyalty, and to investigate the predictors for e-loyalty of shopping mall according to e-promotion interests. A questionnaire was developed based on the previous researches. Data were obtained from 555 adults who had purchased fashion products in online shopping. Data were analyzed using by factor analysis, Cronbach's alpha, t-test and regression. The results showed that consumers with high e-promotion interests were more likely to accept e-promotions affectively and behaviorally, to have hedonic and utilitarian browsing, to satisfy the online shopping, and to make e-loyalty compared to them with low e-promotion interests. For high interested group in e-promotion, the more cognitive and affective attitudes toward promotion acceptance they were the greater e-loyalty in the context of online shopping for fashion products. Additionally, the more hedonic browsing and satisfy the online shopping they were the greater e-loyalty of shopping mall at Internet. However, for low interested group in e-promotion interests, the more utilitarian browsing and satisfy the online shopping they were the greater e-loyalty of online shopping for fashion products. It implies that consumer' e-promotion interest was an influencing variable on promotion-acceptance attitudes, browsing, consumer satisfaction and e-loyalty in online shopping for fashion products. Consumer satisfaction played an important role for making e-loyalty of fashion shopping malls. These findings are discussed in terms of insights for developing the strategies of encouraging to make the loyalty of shopping mall in the context of purchasing fashion products at Internet.
