Effects of different nutrient solutions on growth and flower quality of gerbera (Gerbera jamesonii) grown in hydroponic close system

The nutrient solution is the decisive factor for the growth and development of hydroponic plants. This study was conducted to determine the effect of five nutrient solutions, namely, Hoagland, Knop, Hydro Umat F, BKFAST, and Bio-Life, on the growth and development of gerbera (Gerbera jamesonii) in the hydroponic system. The results show that Hydro Umat F is the most suitable solution for planting gerbera in terms of plant height, number of leaves, leaf size, and root volume. In addition, the flower yield of the gerbera plants nourished on Hydro Umat F is also the highest, with 8.7 flowers per plant after five months in the hydroponic system. The flowers have a diameter of 9.8 cm and natural durability of 19.67 days. Meanwhile, gerbera plants stop growing after 15 days in the Bio-Life solution and 30 days in the Knop solution

EFL TEACHERS’ STRATEGIES AND CHALLENGES IN PROMOTING HIGH SCHOOL STUDENTS’ AUTONOMY IN VOCABULARY LEARNING

Learner autonomy is now regarded as a desirable objective in language teaching. The objective of the study was to identify ELT teachers’ strategies in promoting EFL high school students’ autonomy in vocabulary learning. Besides, this research attempts to find out the challenges that ELT high school teachers employ in promoting EFL students’ autonomy in vocabulary learning. A questionnaire and an interview were used in this study to find out the strategies adopted by the teachers in the current research as well as the challenges they face. The findings of this study revealed that English language teachers frequently promoted autonomous learners in their classrooms. They usually implemented different teaching strategies, which can be categorized into three groups involving students in a student-centered atmosphere; playing various roles in the classroom; and equipping students with the strategies to learn vocabulary. Additionally, the results demonstrated that teachers faced challenges such as learners' lack of independent learning abilities, rules and regulations implemented in schools, and teachers' lack of fundamental ways to promote autonomous learning. Finally, it is hoped that the proposed pedagogical implications will contribute to the innovation of promoting learner autonomy in vocabulary learning in the context of high school in the Mekong Delta of Vietnam.  Article visualizations

Impact of Foreign Direct Investment on Economic Restructuring in Bac Ninh

In recent years, foreign direct investment (FDI) has played an important role in Bac Ninh’s economic restructuring. Of all provinces, Bac Ninh has always been leading the way for attracting foreign investment in Vietnam. The goal of this article is to study the relationship between FDI and the structure of economy of Bac Ninh. We use Ordinary Least Squares regression (OLS) to analyze the influence of the province’s FDI on its economic restructuring over the period from 2009 to 2019. The result partly shows that the FDI has had a strong impact on Bac Ninh’s economic restructuring in both speed and quality. Through these findings, we propose several recommendations for the local authorities to continue to attract the FDI and reinforce the positive impacts of the FDI on the province’s economic restructuring in the future. Keywords: Bac Ninh, foreign direct investment (FDI), economic restructuring, OLS DOI: 10.7176/EJBM/12-15-03 Publication date:May 31st 202

Factors affecting intention to purchase organic agriculture products among Vietnamese

Globally, customer intention to purchase has become the essential part of the product and organization's success in the market. More recently, the idea has captured the attention of academic and policymakers alike. Therefore, the current article analyses product quality features such as agreeableness, emotional stability conscientiousness, openness to experience and extroversion on the intention to purchase organic agricultural products in the context of Vietnam. The study also analyses the mediating role of customer satisfaction between the association of product quality features and intention to purchase organic products in Vietnam. The present study uses questionnaires to collect data pertaining to the health sector of Vietnam. The current study employs the smart-PLS to analyze the constructs and items' reliability as well as the association among constructs. The results show that product quality features except extroversion have a positive and significant association with intention to purchase organic products in Vietnam. The results also reveal that customer satisfaction significantly and positively mediates among the associations of product quality features and intention to purchase organic products in Vietnam. This study is suitable for policymakers while formulating policies that may directly or indirectly affect customers' intention to purchase organic agricultural products.Luong Thu Thuy (Faculty of Economics, Academy of Finance, Vietnam), Tran Thi Phuong Diu (Faculty of Economics, Academy of Finance, Vietnam), Nguyen Dinh Hoan (Faculty of Economics, Academy of Finance, Vietnam), Vu Viet Ninh (Faculty of Economics, Academy of Finance, Vietnam), Nguyen Thi Thuy Nga (Faculty of Economics, Academy of Finance, Vietnam)Includes bibliographical reference

Knowledge of tuberculosis among physicians working at community health stations in Vietnam

Tuberculosis (TB) remains a significant health problem worldwide, including in Vietnam, where around 174,000 newly diagnosed cases and 13,200 patients died in 2018. There are challenges in the diagnostic process, treatment, and follow-up. The physicians with knowledge of TB working at commune health stations play an essential role in this struggle. The primary purpose of this study was to evaluate knowledge of TB and related factors among physicians working at community health stations in the Northern provinces of Vietnam. A cross-sectional survey was implemented on 335 physicians working at community health stations in 5 Northern provinces in Vietnam from September 2019 to October 2020. The result showed that the TB knowledge of physicians was not good. There were some severe knowledge gaps concerning at-risk groups, the main symptoms of TB, sputum tests for both diagnosis and follow-up and management of attack therapy. The TB training participants had better TB knowledge than others (aOR=1.68; 95%CI: 1.047-2.712). This study underlines the importance of clinical experience and TB training to TB knowledge. We suggest that a TB training plan is required for physicians. Our survey results could inform the process of defining the physicians who work at community health stations' role in TB management in the future

The psychological impact of the COVID-19 epidemic among healthcare workers at the grassroots level in Vietnam

The COVID-19 pandemic has significantly affected the mental health of healthcare workers (HCWs). Therefore, an immediate priority is to monitor rates of mental health issues to understand related factors and inform interventions. The main purpose of this study was to evaluate the psychological and mental health impact of COVID-19 and some related factors among HCWs at the grassroots level in Vietnam. A cross-sectional study was conducted on 675 HCWs working at health facilities through questionnaires. The finding showed the rate of HCWs who were psychologically affected by the COVID-19 pandemic was 37.2%, of which 64.1% of HCWs were afraid to tell their families about the risk of exposure to COVID-19 at work. The 31.0% of HCWs had difficulty sleeping deeply/insomnia due to the COVID-19 epidemic. No statistically significant differences were found in the psychological impact of COVID-19 between HCW groups by age, gender, seniority, and professional qualifications. Some groups of HCWs were found to have poor psychological health. Our research suggests that during the COVID-19 pandemic, HCWs working in healthcare facilities experienced an increased psychological burden; psychological interventions for those at high risk and with common mental disorders should be included to reduce this burden and protect HCWs' mental health

An Empirical Study of Affective Commitment: the Case of Machinery Enterprises in Hochiminh City

The study aims to investigate the impact of participation in decision-making (PDM) and perceived organizational support (POS) on affective commitment in machinery enterprises. The study applies structural equation modeling (SEM) to test the research hypotheses. The authors surveyed 220 employees who work in machinery enterprises to collect data for the research. The study results indicate that both PDM and POS positively impact affective commitment. The findings provide empirical evidence to support the theoretical models that PDM and POS have a positive effect on affective commitment. The findings have implications for management theory: PDM and POS are the key antecedents of affective commitment. The findings also have implications for practical management in the machinery enterprises that managers should practice both PDM and POS to increase affective commitment
