In the context of the need to ensure appropriate signalling of the publication of high-quality, international-calibre publications in Vietnam, as well as new policies to improve the quality and effectiveness of scientific research in Vietnam, it is practical to investigate the possibility of developing a national open access database (NOAD). This study aims to answer the question of whether it is necessary to establish a NOAD in Vietnam. We used document analysis to evaluate issues related to NOADs. The results of this study show the complexity, lack of consistency, and difficulty in obtaining practical statistics and assessing research and scientific records in Vietnam today. Furthermore, the findings of this study imply that it is necessary to establish a NOAD of scientific research in Vietnam. The information in this report can be used to develop a NOAD for Vietnam in particular, and for any country that lacks one in general.

Heat shock protein 70 ( HSP70) genes play essential roles in guarding plants against abiotic stresses, including heat, drought, and salt. In this study, the SlHSP70 gene family in tomatoes has been characterized using bioinformatic tools. 25 putative SlHSP70 genes in the tomato genome were found and classified into five subfamilies, with multi-subcellular localizations. Twelve pairs of gene duplications were identified, and segmental events were determined as the main factor for the gene family expansion. Based on public RNA-seq data, gene expression analysis identified the majority of genes expressed in the examined organelles. Further RNA-seq analysis and then quantitative RT-PCR validation showed that many SlHSP70 members are responsible for cellular feedback to heat, drought, and salt treatments, in which, at least five genes might be potential key players in the stress response. Our results provided a thorough overview of the SlHSP70 gene family in the tomato, which may be useful for the evolutionary and functional analysis of SlHSP70 under abiotic stress conditions.

Given principals’ central role in school performance, this study seeks to explore factors that influence school principal competency. The study employed a quantitative research approach. A survey questionnaire was administered to 290 principals across six northwestern mountainous provinces in Vietnam. The questionnaire considered eight areas of principal competency, including self-development and the development of others; school organization and operation; staff development; instructional programme management; education quality assurance management; management of financial resources; engagement with families, community and government; and the school’s strategic planning. Analyses of variance and correlation (Pearson’s r) techniques were used, and the findings demonstrate that principals’ competencies were statistically affected by both internal factors (gender, experience, health, family and IT skills) and external factors (school location, school demographics and school facilities). However, the study found no correlation between principals’ academic qualifications and their competencies.
