The Consumers Using Intention of International E-Commerce
Dao, Duy Thang(따오뒤탕),Hyun, In Gyou(현인규) 한국물류학회 2017 물류학회지 Vol.27 No.4
베트남에서 전자 상거래는 10년 전부터 사용되어 왔지만 최근에는 관세 장벽을 제거함으로써 외국 웹 사이트의 거의 모든 것을 쉽게 구입할 수 있다. 그러나 국경을 초월한 베트남 고객의 사용 의도를 분석하는 방법에 대한 연구는 거의 이루어지지 않았다. 본 연구는 외국 직접 온라인 쇼핑에 대한 고객의 의도 사용에 영향을 미치는 요인을 찾는 것을 목적으로 한다. 고객의 신뢰와 가치의 관점에서 개념 모델을 개발했다. 또한 고객의 신뢰에 대한 정보의 신호, 보안 및 안전, 국가 이미지의 영향을 조사하고, 아울러 고객의 인식 가치에 대한 혜택, 혁신 및 비용의 영향도 조사하였다. 이 연구는 온라인 설문 조사를 사용하여 요인에 대한 설문지를 작성하고 응답을 사용하여 연구 모델을 검증하였다. 연구 결과는 연구자와 실무자가 국경 간 전자 상거래에 대한 호치민시의 고객의 장벽과 행동을 이해하고 이익을 창출하는 전략을 고안하는 데 도움이 될 수 있을 것이다. Vietnam E-commerce has been used and developed 10 years ago but recently, with removing tariff barriers, Vietnam’s customers can easily buy almost everything in the foreign website. However, little research has been done to study how to analyze customer’s using intention on across national borders. This study aims to find the factors that affect customer’s using intention on foreign direct online shopping. A conceptual model is developed from the perspectives of customer’s trust and value. We also examine the impact of information’s signal, security and safe, a country image on customer’s trust, as well as the impact of benefits, innovation, and costs on customer’s perceived value. This study uses an online survey to make questionnaire about the factors and uses the answers to test the research model. Our findings can help researchers and practitioners understand the barriers and behavior of Ho Chi Minh City’s customers to cross-border e-commerce and devise strategies to make profit.
Microscopic Investigation of the Magnetic Saturation Process for Co/Pt Multilayers
Duy-Truong Quach,Dong-Hyun Kim,Kyung-Min Lee,정종율,Duc-Thang Pham 한국물리학회 2016 THE JOURNAL OF THE KOREAN PHYSICAL SOCIETY Vol.69 No.1
We have systematically investigated the magnetic saturation process for Co/Pt multilayers with perpendicular magnetic anisotropy by using the first-order reversal-curve (FORC) technique. We find that even for a field that apparently is higher than the major-loop saturation field, some microscopically not-yet-annihilated domains still remain. The true saturation on a microscopic scale field is found to be about 1.5 to 2.5 times greater than the macroscopicall-determined majorloop saturation field. Not-yet-annihilated domains are observed to be exponentially reduced with respect to the applied magnetic field.

<P><B>Abstract</B></P> <P>We report our local X-ray absorption spectra (XAS) measurement mapping for a Co/Pt multilayer using scanning transmission microscopy with 25-nm spatial resolution and 0.1-eV spectral resolution. We have systematically analyzed the two-dimensional XAS intensity variation over the corresponding magnetic domain patterns, revealing a XAS profile across the magnetic domain wall as well as the simultaneous high-throughput measurement of local XAS spectra.</P>

This study is empirically to examine relationship of Vietnam Online Shopping Mall Characteristic, System Quality and Consumer Reuse. Data was collected by administering a survey to consumer used online shopping mall. The survey questionnaire comprised of a 5-point Likert scale. The demographic analysis was conducted using the frequency analysis method and relationship of variable was conducted using the EFA analysis, reliability analysis, multiple regression analysis. The results of study are “online shopping mail characteristic effect to consumer satisfaction”, “system quality effect to consumer reliability” but “System interactivity don’t effect to consumer Reliability”, and “consumer reliability and satisfaction effect to Consumer reuse Intention”.

In this research, a simple method has been presented to synthesize the magnetic - semiconductor Fe₃O₄/TiO₂ heterostructure nanocomposites via three steps: firstly, synthesis of Fe₃O₄ nanoparticles by co-precipitation method; thereafter, formation of Fe₃O₄/TiO₂ composites by sol-gel method; finally, annealing to form Fe₃O₄/TiO₂ anatase (denoted as Fe₃O₄/TiO₂-A) and Fe₃O₄/TiO₂ rutile (denoted as Fe₃O₄/TiO₂-R) heterostructure nanocomposites, respectively. The results of X-ray diffraction, transmission electron microscopy, and energy-dispersive X-ray spectroscopy show that the Fe₃O₄/TiO₂-A and Fe₃O₄/TiO₂-R heterostructure nanocomposite samples contain both magnetite (Fe₃O₄) and semiconductor TiO₂ (anatase or rutile phase, respectively). The asprepared nanocomposite samples exhibit superparamagnetic properties at room temperature with high saturation magnetization (Ms) above 19.5 emu/g at the applied magnetic field of 11 kOe. Moreover, the Fe₃O₄/TiO₂-A and Fe₃O₄/TiO₂-R heterostructure nanocomposites with a low band gap energy of 2.89 eV and 2.81 eV, respectively, are promising to enhance the performance of photocatalytic activities in the visible light region for application in wastewater treatment.
