Dataset of Vietnamese preschool teachers' readiness towards implementing STEAM activities and projects.

STEAM education has significant impacts on improving preschoolers' learning engagement, cognition, confidence, and innovative thinking skills. The integration of content about local culture into STEAM projects also triggers students' awareness and engagement with surrounding communities and societies. However, teachers' competencies and willingness to implement STEAM activities are irreplaceable in determining STEM projects' frequency and effectiveness. This dataset surveyed 754 preschool teachers across ten cities and provinces in Vietnam from 8 Apr 2022 to 15 May 2022. The dataset includes seven main sections: (i) Demographics; (ii) Teachers' know-how about STEAM education; (iii) Teachers' competencies; (iv) Conditions to implement STEAM projects; (v) School policies; (vi) Local culture factors integrated with STEAM projects; and (vii) Teachers' willingness to implement STEAM education.

Copper Tolerance of Novel Rhodotorula sp. Yeast Isolated from Gold Mining Ore in Gia Lai, Vietnam.

In this study, twenty-five yeast strains were isolated from soil samples collected in the gold mining ore in Gia Lai, Vietnam. Among them, one isolate named GL1T could highly tolerate Cu2+ up to 10 mM, and the isolates could also grow in a wide range of pH (3-7), and temperature (10-40 °C). Dried biomass of GL1 was able to remove Cu2+ effectively up to 90.49% with a maximal biosorption capacity of 18.1 mg/g at pH 6, temperature 30 °C, and incubation time 60 min. Sequence analysis of rDNA indicated this strain was closely related to Rhodotorula mucilaginosa but with 1.53 and 3.46% nucleotide differences in the D1/D2 domain of the 28S rRNA gene and the ITS1-5.8S rRNA gene-ITS2 region sequence, respectively. Based on phylogenetic tree analysis and the biochemical characteristics, the strain appears to be a novel Rhodotorula species, and the name Rhodotorula aurum sp. nov. is proposed. This study provides us with more information about heavy metal-tolerant yeasts and it may produce a new tool for environmental control and metal recovery operations.

Mechanical properties of steel slag replaced mineral aggregate for road base/sub-base application based Vietnam and Japan standard.

Steelmaking slag is one of the most massive industrial by-products generated during steelmaking processes. This paper presents the current steelmaking slag production status and its potential to use as mineral aggregates in base/sub-base layer of road pavement. The mechanical properties of steelmaking slag were confirmed by the test method specified in Vietnam specification. The volume stability test of the slag was conducted based on JIS A 5015-2018 (Japanese Industrial Standard: Iron and steel slag for road construction). From the results, it was confirmed that steelmaking slag can satisfy all the mechanical requirements specified in Vietnam specification and the requirements regarding stability specified in JIS A 5015-2018. In addition, it was found that the elastic modulus of steelmaking slag applied as a base or sub-base layer in pavement was higher than that of the conventional graded aggregate made from mineral aggregate. Therefore, the thickness of pavement can be reduced by using steelmaking slag, and the construction cost can be lower.

Dataset of Vietnamese teachers' perspectives and perceived support during the COVID-19 pandemic.

The COVID-19 pandemic has caused unprecedented damage to the educational system worldwide. Besides the measurable economic impacts in the short-term and long-term, there is intangible destruction within educational institutions. In particular, teachers - the most critical intellectual resources of any schools - have to face various types of financial, physical, and mental struggles due to COVID-19. To capture the current context of more than one million Vietnamese teachers during COVID-19, we distributed an e-survey to more than 2,500 randomly selected teachers from two major teacher communities on Facebook from 6th to 11th April 2020. From over 373 responses, we excluded the observations which violated our cross-check questions and retained 294 observations for further analysis. This dataset includes: (i) Demographics of participants; (ii) Teachers' perspectives regarding the operation of teaching activities during the pandemic; (iii) Teachers' received support from their schools, government bodies, other stakeholders such as teacher unions, and parents' associations; and (iv) teachers' evaluation of school readiness toward digital transformation. Further, the dataset was supplemented with an additional question on the teachers' primary source of professional development activities during the pandemic.

Study on the gastrointestinal manifestation in malaria

486 case-record files of malaria patients admitted to Tropical Disease hospital, of mahidol University, Bangkok,Thai land from November 1st, 1999 to December 31st 1999. P.falciparum and P.vivax are most popular parasitic species. The personal history of malaria also affect to disease. The incidences of nausea, vomitting, abdominal pain and hepatomegaly in falciparum malaria were higher than those in vivax malaria patients in restrospective. It was noted that, Gl symptoms were th most common findings in severe and complicated malaria

Associated treatment of cerebral malaria

Celebral malaria is the most common complications of plasmodium falciparum with a mortality of 20-50%. Apart from special chemotherapy, some additional therapies were applied. Fever relief: in addition of physical method of hypothermy, ventilation, freezing compress, ... paracetamol is recommended. Antiseizure: intravenous diazepam can be infected slowly with 10mg in adults and 0,15mg/kg in children. Blood replaced perfusion is rather an increase of parasite count than a simple special medication, safely regulating severe anemia in patient with circulation overload is recommended only for very severe subjects, with very high level of parasity in blood
