In vitro in screening test aiming to find monoamine oxidase (MAO) inhibitors from Vietnamese medicinal plants, the MeOH extracts of seventeen medicinal plants were tested for the inhibitory effects on monoamine oxidase activity. MAO was purified from mouse brain and its activity was determined by fluorospectrophotometer using kynuramine as a substrate. Five MeOH extracts of medicinal plants including Cnidium monnineri showed quite strong inhibitory effects at the concentration of 250 ㎍/㎖. Six MeOH extracts of herbs including Astragalus membranaceus showed moderate inhibitory effects on this enzyme. Seven medicinal plants which showed good inhibitory effects on MAO were fractionated with CH_2Cl_2, EtOAc, BuOH and H_2O, successively. They were investigated for the inhibitory effects on MAO.

Currently, small and medium-sized enterprises (SMEs) are accounting for about 98% of the total number of enterprises in Vietnam. Each year, SMEs create over one million new jobs, utilize up to 51% of the labor force in the society, and contribute more than 40% of GDP to the country. The study aims to analyze factors affecting the management competency of directors in small and medium enterprises in Vietnam. To achieve these research objectives, quantitative and qualitative methods were used concurrently. 300 questionnaires were sent out, but only 276 were collected and used for the quantitative analysis through SPSS 20.0 software. Cronbach’s Alpha, EFA, and regression were used to further confirm the research findings. The research findings show that all four proposed factors have impacts on the management competency of SME directors, among which enterprise features and specific policies for entrepreneur development in the locality have the strongest impacts, followed by personal features and business environment. The findings of this study suggest that managers need to focus on factors affecting the management competency of directors. This paper also provides new insight into the management competency of directors. Based on the findings, some recommendations are given for SMEs to improve management competency.

LE Thi Lan Huong,HOANG Vu Hiep,HOANG Mai Duc Minh,NGUYEN Hong Phuc,BUI Xuan Bach 한국유통과학회 2022 유통과학연구 Vol.20 No.6

Purpose: This research aims to provide empirical evidence on the impact of digital literacy on behavioural intention regarding using technology for distribution of higher education. Design, Methodology, and Approach: Quantitative analysis was carried out using Covariance-Based Structural Equation Model with data collected from 901 students who fully experienced 2-year study online at different universities in Vietnam. The structural model was built with digital literacy as the primary indicator and other variables were included based on modified version of Unified Theory of Acceptance and Use of Technology (UTAUT2) by adopting performance expectancy, effort expectancy, social influence, habit, and hedonic motivation variables specifically for education sector. Self-efficacy was added to eliminate possible bias in technology acceptance. Results: From the results of model estimation, digital literacy presented positive impact on the online distribution of higher education in Vietnam. The mediating effects of various indicators such as performance expectancy, effort expectancy, social influence, habit, hedonic motivation, and self-efficacy are significantly determined by research model. Conclusion: The higher level of digital literacy of the students, the more likely that they will use technology in higher education study, especially online learning. Additionally, the mediating effects of indicators from the UTAUT2 theoretical model were also evident to be positively significant.

Van Vien VU,Van Hao HOANG,Lan Huong VU 한국유통과학회 2024 유통과학연구 Vol.22 No.2

Purpose: Although many studies have addressed destination marketing concepts, the relationship between beach tourists’ memorable tourism experience (MTE), revisit intention and electronic word of mouth (eWOM) remains unknown. To address this issue, the authors established a model to investigate the effects of MTE’s dimensions on revisit intention and eWOM. Research design, data and methodology: Drawing on 581 questionnaires from domestic beach tourists in Vietnam, a quantitative study approach was administered to empirically analyze a partial least squares path model in PLS-SEM. Results: The findings revealed that four dimensions of MTE including hedonism, local culture, meaningfulness and involvement have positive influence on beach tourists' revisit intention. Besides, meaningfulness and knowledge directly affect eWOM. It is worth noting that beach tourists' revisit intention significantly and directly influence their eWOM. The findings also confirm the indirect effects of hedonism, local culture, meaningfulness and involvement on eWOM through the mediating role of revisit intention. Conclusions: This study will be important to determine beach tourists’ behavior through each dimension of MTE. This study also emphasizes on the direct effect of beach tourists’ revisit intention on eWOM, as well as confirms its mediating role in the relation between MTE and eWOM. The findings will assist policymakers and destination marketers with strategies and effective future actions.

Objectives: The average alcohol consumption per capita among Vietnamese adults has consistently increased. Although alcoholrelated disorders have been extensively studied, there is a paucity of research shedding light on this issue among Internet users. The study aimed to examine the severity of alcohol-related disorders and other associated factors that might predispose individuals towards alcohol usage in a sample of youths recruited online. Methods: An online cross-sectional study was conducted with 1,080 Vietnamese youths. A standardized questionnaire was used. Respondent-driven sampling was applied to recruit participants. Multivariate logistic and Tobit regressions were utilized to identify the associated factors. Results: About 59.5% of the males and 12.7% of the total youths declared that they were actively using alcohol. From the total sample, a cumulative total of 32.3% of the participants were drinking alcohol, with 21.8% and 25.0% of the participants being classified as drinking hazardously and binge drinkers, respectively. The majority of the participants (60.7%) were in the pre-contemplative stage. Conclusions: A high prevalence of hazardous drinking was recognized among online Vietnamese youths. In addition, we found relationships between alcohol use disorder and other addictive disorders, such as tobacco smoking and water-pipe usage. Our results highlighted that the majority of the individuals are not receptive to the idea of changing their alcohol habits, and this would imply that there ought to be more government effort towards the implementation of effective alcohol control policies.

Objectives: The incidence of posttraumatic stress disorder (PTSD) has increased, particularly among individuals who have recovered from coronavirus disease 2019 (COVID-19) infection. Health literacy is considered a “social vaccine” that helps people respond effectively to the pandemic. We aimed to investigate the association between long COVID-19 and PTSD, and to examine the modifying role of health literacy in this association.Methods: A cross-sectional study was conducted at 18 hospitals and health centers in Vietnam from December 2021 to October 2022. We recruited 4,463 individuals who had recovered from COVID-19 infection for at least 4 weeks. Participants provided information about their sociodemographics, clinical parameters, health-related behaviors, health literacy (using the 12-item short-form health literacy scale), long COVID-19 symptoms and PTSD (Impact Event Scale-Revised score of 33 or higher). Logistic regression models were used to examine associations and interactions.Results: Out of the study sample, 55.9% had long COVID-19 symptoms, and 49.6% had PTSD. Individuals with long COVID-19 symptoms had a higher likelihood of PTSD (odds ratio [OR], 1.68; 95% confidence interval [CI], 1.63–2.12; p<0.001). Higher health literacy was associated with a lower likelihood of PTSD (OR, 0.98; 95% CI, 0.97–0.99; p=0.001). Compared to those with long COVID-19 symptoms and the lowest health literacy score, those with long COVID-19 symptoms and a 1-point health literacy increment had a 3% lower likelihood of PTSD (OR, 0.97; 95% CI, 0.96–0.99; p=0.001).Conclusion: Health literacy was found to be a protective factor against PTSD and modified the negative impact of long COVID-19 symptoms on PTSD.
