This study aimed at elucidating the present situation of scholarly journals published in Vietnam according to the minimum criteria to be indexed in the ASEAN Citation Index (ACI) and Scopus, with the goal of suggesting development strategies for scholarly journals in Vietnam. From the 387 journals accredited by the Vietnamese State Council for Professorship, 13 education journals were arbitrarily selected, and their compliance with the five minimum criteria for the ACI (peer review, timeliness, abstracts in English, references in Roman script, and a website in English) and the six minimum criteria for Scopus (peer review, timeline, abstracts in English, references in Roman characters, Electronic International Standard Serial Number [ISSN], and publication ethics) were assessed. Two of the 13 journals were eligible to be indexed in the ACI, while none fulfilled the minimum criteria to be indexed in Scopus. An urgent task for the editors of those journals is to establish an informative journal homepage in English that provides basic information on the journal. Then, an Electronic ISSN can be obtained from the ISSN International Center. Furthermore, the following steps are suggested for journal promotion: establishment of appropriate editorial policies and publication ethics procedures, improvement of research integrity, enhancement of the journals’ reputation in the international scientific community, and improvement of the online publishing system by adopting a journal manuscript management system. To achieve those goals, financial support from the Vietnamese government will be invaluable.

Purpose: This study aimed to analyze the bibliographic characteristics and content of articles on education published in Scopus-indexed journals by authors with Vietnamese affiliations from 2009 to 2018. Methods: Scopus was searched on July 6, 2019 using the search option “affiliation country,” with “Vietnam OR Viet Nam” as the country name, and “subject area” as “social sciences AND education.” Results: A total of 193 articles were identified. They were classified by publication year, co-authors’ country, affiliation, subarea, journal, and author. Content analysis of these articles demonstrated that the number of publications on education from Vietnam in Scopus increased rapidly during the last 10 years. The top five countries of co-authors were Australia, the USA, New Zealand, the UK, and the Netherlands. The main research subfields were English-language teaching, pedagogy, and educational management. Conclusion: Although Vietnamese education researchers collaborated with colleagues in developed countries to publish papers, there was still a lack of articles discussing global trends in education, such as cross-border education, equity in education, and international assessment programs.

This paper presents an Adaptive Cuckoo Search Algorithm (ACSA) for solving economic load dispatch problem where thermal units with multiple fuel options and valve point loading effect are taken into account. ACSA is first developed by improving the optimal solution search ability of conventional Cuckoo search algorithm. In ACSA, the initial eggs are evaluated and classified into two groups including good group and bad group. The updated step size in ACSA at the first new solution generation via Lévy is adaptive at each iteration and therefore the selection of the parameter is not an issue in the paper. The proposed ACSA method is tested on a ten-unit system considering multiple fuel options and valve point loading effect with different load cases. The comparisons of obtained results among the proposed method with others reported in the paper have indicated that ACSA is efficient for applying to the problem.

In vitro conservation is one of the most effective strategies for rare plant protection, especially for orchid species. To maximize the success rates of in vitro explant establishment (stage I) in conservation programs, the application of tissue culture additives such as Plant Preservative MixtureTM (PPMTM) should be emphasized. In this study, we used Dendrobium thyrsiflorum Rchb.f. (1875) seeds and seedlings as a model for the evaluation of PPMTM’s phyto- toxicity in the meristematic tissues of epiphytic orchids. PPMTM had no observable inhibitory effect on protocorm, shoot, or root development when it was supplemented at 0.1%. PPMTM supplementation caused adverse effects on D. thyrsiflorum explants at concentrations > 0.2%. At high concentrations, young in vitro seedlings showed damage, especially at the root tissue level. Based on this model, supplementation of 0.1-0.2% PPMTM to culture media was successfully implemented to establish in vitro cultures of other rare orchid species in our conservation program.

This paper proposes an intelligent system performing an application with assistance of an Internet of Things (IoT) platform to control a traffic lights system. In our proposed systems, the traffic lights can be remotely controlled through the Internet. Based on IoT platform, the traffic conditions at different intersections of roads are collected and the traffic lights are controlled in a central manner. For the software part, the algorithm is designed based on the green wave theory to maximize the green bandwidth of arterial roads while addressing a challenging issue: the rapid changes of parameters including cycle time, splits, offset, non-fixed vehicles' velocities and traffic flow along arterial roads. The issue typically happens at some areas where the transportation system is not well organized like in Vietnam. For the hardware part, PLC S7-1200 are placed at the intersections for two purposes: to control traffic lights and to collect the parameters and transmit to a host machine at the operation center. For the communication part, the TCP/IP protocol can be done using a Profinet port embedded in the PLC. Some graphical user interface captures are also presented to illustrate the operation of our proposed system.

The goal of this study was to develop an adsorptive membrane based on electrospun graphene oxide/poly(vinylidene) fluoride fiber mat coated with chitosan (GO-PVDF/CS composite membrane) which can potentially be used to remove Mn2+ from aqueous solutions by a continuous filtration process. This composite membrane was composed of two layers: the first layer was the electrospun PVDF fiber mat containing GO, supporting mechanical strength, improving hydrophilicity, and providing adsorptive sites; the second layer was a thin CS film coated on top of the first layer with the aim of significantly enhancing hydrophilicity and adsorption capacity of the composite membrane. The hydrophilicity and porosity of the GO-PVDF/CS composite membrane depended on the concentration of the CS solution, subsequently affecting the Mn2+ removal efficiency of the membrane. The GO-PVDF/CS membrane achieved the maximum Mn2+ removal efficiency of 90.7 wt% by a continuous flow filtration process with a flux of 157.3 L.m-2.h-1.bar-1. The GO-PVDF/CS membrane was able to decrease the concentration of Mn2+ from 5.72 to 0.38 mg/L in the groundwater-contaminated Mn2+ after two filtration processes, reaching the notification level of Mn2+ for drinking water that was allowed by several countries. Therefore, the GO-PVDF/CS membrane can be an effective adsorptive filtration membrane used to remove Mn2+ from groundwater.
