Preliminary development of the Vietnamese Marital Satisfaction Scale (MSS-VN): a pilot study using a Vietnamese intellectual sample

BackgroundThe objective of the present study was to develop a scale to measure marital satisfaction within a Vietnamese context (Vietnamese Marital Satisfaction Scale – MSS-VN). Due to the lack of in-depth studies in Vietnam on marital satisfaction, as well as a paucity of specialized Vietnamese context measurement tools in this field, the marital satisfaction dimensions of the MSS-VN were based on extant research literature and the social-cultural context of Vietnamese intellectual couples.Participants and procedureA group of 10 Vietnamese intellectuals (ages 28 to 43 years, five males/five females) were used to vet the MSS-VN questions during the question development phase of the study. The final version of the MSS-VN was administered to a convenience sample consisting of 144 male and 145 female Vietnamese intellectuals (age 22 to 50 years, M = 31.60, SD = 5.40). Analysis involved tests of reliability and validity (internal consistency, content validity, and convergent validity).ResultsThe results in the exploratory factor analysis of the MSS-VN indicated the maintenance of 33 items, distributed in five factors: emotional support, division of responsibilities and housework, child-rearing, decision making and financial management, and cohesion. The convergent validity showed rather strong correlation between the final scale solution and the sub-scale “dyadic satisfaction” from the Dyadic Adjustment Scale of Spanier.ConclusionsThe MSS-VN was considered satisfactory for the proposed intent of developing a measure of marital satisfaction within a Vietnamese context, with consistency for application in other studies on Vietnamese intellectual’s marital satisfaction; however, due to the limitation of the convenience sample, further evidence on the validation of the MSS-VN is required.BackgroundThe objective of the present study was to develop a scale to measure marital satisfaction within a Vietnamese context (Vietnamese Marital Satisfaction Scale – MSS-VN).

Quality properties Of Vietnamese cocoa liquors

Vietnam (VN) is an emerging country targeting cocoa as a potential industrial domain. It is however still unclear how the quality of VN cocoa liquors can be positioned in the world cocoa supply. Three VN cocoa liquors exhibiting high to intermediate acidity (pH: 4.7 – 5.2) were selected to produce dark chocolate (48.0% sugar, 17.6% cocoa solids, 34.0% cocoa butter and 0.4% lecithin). A comparison study was conducted to investigate the difference between VN and Ghanaian (GH; pH: 5.6) dark chocolates in terms of Casson flow properties (yield stress sCA and viscosity hCA), hardness (F 20°C and F 30°C), water-soluble organic acid content, aroma profile and sensory evaluation. The impact of pre-treatments of cocoa liquor by ball-milling at different fat contents and conching (-C) was also examined

Extraction of Silica and Iron Oxide from Municipal Solid Waste Incineration Ash and Biomass-fired Power Plant and It’s Application in the Production of Magnetic Mesoporous Silica for Tetracycline Adsorption

Master of Science (Environmental Management), 2023Municipal solid waste incinerator and biomass power plant byproducts, namely bottom ash (BA) and fly ash (FA), are rich in silica and represent a potential source for the synthesis of silica-based materials. This study investigated the optimal conditions for alkaline fusion to extract silica from BA and FA, resulting in a supernatant solution that served as the source of silica for Magnetic mesoporous silica synthesis. To separate Fe2O3 from the ash, a low-temperature hydrothermal reaction was conducted using acid leaching, followed by efficient separation and extraction with methyl alcohol. Before experimentation, the mineralogical composition of the ashes was determined using X-ray fluorescence. Fourier transform-infrared (FTIR), X-ray diffraction (XRD) pattern, and scanning electron microscopy (SEM) were utilized to analyze the extracted silica and iron oxide from the ashes. Sequential extraction under these conditions yielded 71% extraction efficiency and 81% silica purification. However, the efficiency and purity of iron oxide separation are both relatively low. Subsequently, the silica and magnetic ash derived from the bottom ash were used to synthesize magnetic mesoporous silica (MMS) with a high adsorption capacity TC of 276.74 mg/g. FTIR, XRD, and SEM were also employed to characterize the MMS. Optimal conditions for overnight incubation at 60 °C and a pH of 6-8 were determined. The Langmuir isotherm and pseudo-second-order kinetic models were the optimal fitting models based on isotherm and kinetic equations. The adsorption process was identified as physisorption and spontaneous, as evidenced by the low entropy changes (ΔS°), negative enthalpy changes (ΔH°) of -15.94 kJ/mol, and negative Gibbs free-energy changes (ΔG°).Thailand Science Research and Innovation (TSRI), grant number 652A01012; Graduate Research Development Grant of Prince of Songkla University

The application of phosphor Sr4La(PO4)3O:Ce3+,Tb3+,Mn2+ on white light-emitting diodes

Using a high temperature solid-state technique, various phosphors Sr4La(PO4)3O:Ce3+, Tb3+,Mn2+ (SLPO:Ce,Tb,Mn) were produced. In Sr4La(PO4)3O, the luminescence characteristics, thermal stability, and energy conversion between Ce3+ and Tb3+-Mn2+ have been thoroughly studied. The sensitizer Ce3+ particles inclusion could considerably improve the feeble Tb3+ green radiation and Mn2+ red radiation via energy transfer. By adjusting the scale of Ce3+/Tb3+ over Ce3+/Mn2+ atoms, the color of the emission may be changed. White light was produced in the Sr4La(PO4)3O:0.12Ce3+,0.3Mn2+ specimen with chromatism coordinates of (0.3326, 0.3298), showing that the phosphors SLPO:Ce,Tb,Mn possess promising application on WLEDs. The conclusion is supported by Mie-scattering theory and Lambert-Beer's law

Color-adjustable phosphors Sr4La(PO4)3O:Ce3+,Tb3+,Mn2+ impact on luminescence of white light-emitting diodes

We used the ceramic approach to synthesize a sequence of Sr4La(PO4)3O:Ce3+,Tb3+,Mn2+ within our study. Especially, the attributes of Sr4La(PO4)3O that were extensively investigate are luminous characteristics, thermal stableness, and energy transfering from Ce3+ to Tb3 and Mn2+.Through energy transfer, sensitizer Ce3+ ions can considerably boost the fragile green radiation from Tb3+ and red radiation from Mn2+. The color of the radiation can be changed by adjusting the Ce3+/Tb3+ and Ce3+/Mn2+ ion ratios. The Sr4La(PO4)3O: 0.12Ce3+, 0.3Mn2+ specimen produced white light having hue coordinates of (0.3326, 0.3298). According to this result, it shows that Sr4La(PO4)3O:Ce3+,Tb3+,Mn2+ might be used in white light-emitting diodes (WLEDs)

Exploring Digital Literacy of University Students and Variables Affecting Digital Literacy Levels

Considered a pressing need for students in the 21st century, digital literacy is indispensable to navigate the digital world as much as the real world. This study aims to gain a comprehensive understanding of current Vietnamese university students’ digital literacy levels and to see if there is any difference between their digital literacy levels in terms of gender as well as regional settings among undergraduate students in Vietnamese universities. A mixed-methods approach included a questionnaire administered to 300 Vietnamese university students, semi-structured interview with 25 of them, was applied to collect the data. After analyzing the data, the findings indicated that Vietnamese students considered their digital competencies at good levels. In addition, there was a significant difference in digital transformation skills among undergraduate students in various parts of the country. In addition, the difference in genders did not result in distinct digital literacy levels. In light of the findings, some pedagogical implications are put forward with a view to improving university students’ digital ability and hence supporting the development of technology education in Vietnamese context

Job Satisfaction, Leadership Styles, Demographic Variables and Organisational Commitment among Pharmacists in Vietnam

Research Aims: To analyse the organisational commitment of pharmacists in Vietnamese enterprises, incorporating elements such as job satisfaction, leadership style and demographic variables. Design/Methodology/Approach: Based on a primary data sample, collected from 300 pharmacists in professional organisations (universities, hospitals, pharmaceutical companies and drugstore chains), and a structural equation model (SEM). Research Findings: The results show that organisational commitment is significantly dependent on perceived job satisfaction, leadership styles and demographic variables by pharmacists. Predictors of pharmacists\u27 organisational commitment differed significantly. Theoretical Contribution/Originality: This is the first study to consider factors affecting organisational commitment among pharmacists in Vietnamese enterprises. Managerial Implications in the Southeast Asian Context: This study could have potential practical implications in pharmacy management. Human resource management systems in each type of organisation (universities, hospitals, pharmaceutical companies and drugstore chains) must be aware of different predictors that affect the pharmacists\u27 commitment to their respective organisations and devise appropriate managerial standards. Research Limitations and Implications: Earlier research has shown that some control variables, such as age, gender, marital status, number of years in an organisation and level of education, which influence organisational commitments in particular, were not included in the model as direct control variables. Further research should use these control variables in their models to obtain a more complete explanation of organisational commitment among pharmacists in Vietnam
