This study aims to assess the attraction of foreign direct investment in Vietnamese economic zones (including industrial zones and economic zones). The main research method used are synthesis and comparison analysis based on the data collected from the surveyed group comprising of enterprises operating in the economic zones in the Middle (Chu Lai, Nhon Hoi, Dung Quat) and the Southern (the largest island: Phu Quoc). After conducting surveys, research results show that there is a difference between the assessment and the level to meet the requirements of investors with business environment, expressed through the following criteria: (1) the infrastructure; (2) quality of public services; (3) preferential policies; (4) labor; (5) market; and (6) social services. Based on the assessment of the identified criteria, this paper had suggested six number of recommendations to promote the role of attracting foreign direct investment capital into the economic zones in Vietnam: (1) implementing the one-stop-shop policy; (2) continuing to improve the infrastructure of economic zones; (3) prevent and ensure the security of economic zones; (4) implementing vocational training activities to improve quality of human resources; (5) development of supporting industries; (6) raising the quality of capital invested in the economic zone.

Based on the assessment of the identified criteria, this paper had suggested six number of recommendations to promote the role of attracting foreign direct investment capital into the economic zones in Vietnam: (1) implementing the "one-stop-shop" policy; (2) continuing to improve the infrastructure of economic zones; (3) prevent and ensure the security of economic zones; (4) implementing vocational training activities to improve quality of human resources; (5) development of supporting industries; (6) raising the quality of capital invested in the economic zone

In this work, a lactose biosensor was developed by co-immobilizing b-galactosidase (b-Gal) and glucose oxidase (GOx) on microelectrodes pre-modified with Pt/graphene/P(1,5-DAN) for estimation of lactose in dairy products to prevent lactose intolerance. The Pt microelectrode was modified with graphene and 1,5-polydiaminonaphthalene film. Graphene was synthesized by chemical vapor deposition on copper tape and manually transferred to the electrode surface. Polymeric P(1,5-DAN) was grafted on top of the graphene film by electropolymerization. Modified surface of the electrode was characterized by Raman spectra analysis, FE-SEM, AFM and cyclic voltammetry. The results indicated that deposition graphene film on electrode surface induced considerable enhancement in current signal, over 20 times as high as the uncoated electrode surface. The developed sensor was successfully used to determine lactose in model samples with sensitivity, correlation coefficient (R2) and limit of detection (LOD) estimated to be 1.33 mA/(mgml1), 0.995 and 1.3 mg/ml, respectively. The combined graphene and conductive P(1,5-DAN) could serve as a novel sensing platform on electrochemical sensors with superior sensitivity.

Nanocomposites containing two or more functional constituents are attractive candidates for advanced nanomaterials. In this study, multifunctional Ag/Fe3O4-CS nanocomposites were successfully prepared, using chitosan as a stabilizing and cross-linking agent. The as-synthesized nanocomposites were characterized by Transmission Electron Microscopy (TEM), Scanning Electron Microscopy (SEM), X-ray diffraction (XRD), Energy-dispersive X-ray spectroscopy (EDS), UVevisible spectrophotometer (UVeVis) and vibrating sample magnetometer (VSM). The results demonstrated that Ag/Fe3O4-CS composite nanoparticles (NPs) were composed of parent components, Fe3O4 and Ag NPs, which were uniformly dispersed in the chitosan matrix. The hybrid NPs exhibited strong antibacterial property against Pseudomonas aeruginosa. With high magnetization value (67 emu/g), the synthesized Ag/Fe3O4-CS composite can be easily separated or recycled in potential biomedical applications. Furthermore, the results showed that the multicomponent hybrid nanostructures appeared to be the promising material for local hyperthermia, which can be used as thermoseeds for localized hyperthermia treatment of cancers.

Going beyond Border? Intention to Use International Bank Cards in Vietnam
Dzung Tran Trung PHAN,Thanh Thi Ha NGUYEN,Tuan Anh BUI 한국유통과학회 2019 The Journal of Asian Finance, Economics and Busine Vol.6 No.3
The paper aims to explore the factors affecting potential users of international bank cards in Vietnam. With milestones treaties being signed CPTPP and EVFTA, Vietnam is now exposing itself to the international open environment. Bank card market is at the core of this wind of change, and that is the reason for us to research the intention to use international bank cards. Given that the decision to choose international bank cards could either be the switch from domestic cards or adopting a brand new card, we develop some specific constructs to reflect that consideration, specifically PE and PD, asides from traditional constructs used in TPB and TAM frameworks. The analysis work is conducted using PLS-SEM approach. Our findings reveals that most of our proposed hypotheses are supported, in which SN plays the most important direct role to INT, while total effect of PU on INT is similar to that of SN. The newly introduced PD negatively and significantly impacts INT, and PE also has a positive impact on INT. The findings suggest that overall, it is important for bank card issuers to have a balance approach to the market, with focus on increasing usefulness and reducing potential disadvantages of international bank cards.
