Purpose - Based on the extended theory of planned behavior (TPB), this study aims to investigate the antecedents of online purchase behavior toward organic cosmetics for Generation Z (Gen Z) and Millennials by focusing on the impact of subjective norms, health consciousness, trust, attitude, and intention. Design/Methodology/Approach - A survey method using an online questionnaire was adopted to collect data from 341 Gen Z and Millennial consumers in Vietnam. The collected data were then analyzed using structural equation modeling (SEM). Findings - The results of the study showed that, among antecedents, that attitude has the strongest impact on the purchase intention of online customers toward organic cosmetics, followed by trust and subjective norms. Interestingly, health consciousness has also been found to significantly impact Gen Z and Millennial online purchase intention toward organic cosmetics. Research Implications - This paper extends the academic literature on purchase intention toward green products. More importantly, to the best of the authors’ knowledge, this study is among the first to examine the antecedents of online purchase intention toward the organic cosmetics of Gen Z and Millennials in an emerging economy, Vietnam. The findings offer important implications for cosmetics companies, retailers, and other stakeholders to have deeper insights into factors influencing young Vietnamese consumer intentions toward purchasing organic beauty products online.

Different kinds of materials for electrodes based on glassy carbon, carbon fibers, and modified by an ionic liquid (BMIMBF4) were used to determine 2,4,6-trinitrotoluene (TNT) in water environment by differential pulse adsorptive stripping voltammetry. The modified electrode based on BMIMBF4 showed a better performance than those based on the microelectrode and glassy carbon electrode (GCE) in term of sensitivity. The best performance was obtained with the ionic liquid-modified electrode with 80:10:10 (w/w/w) of the graphite powder/paraffin oil/BMIMBF4 composition in PBS, pH 8. The TNT concentration was linear in the range 1.5 to ~30 ppm for all studied electrodes (r = 0.9978) with a detection limit of 88.6 ppb using IL-CPE (ionic liquid-modified carbon paste electrode). This latter electrode was used to measure real samples taken from Red River, Vietnam. The recovery study for TNT in natural samples gave values from 99.7% to 103.3%. IL-CPE demonstrated long-term stability and reproducibility, with a relative standard deviation of 1.67%.

NGUYEN, Thi Hanh Duyen,LE, Van Luyen,HAU, Nguyen Van,DO, Duc Tai,THAO, Nguyen Thi Thu Korea Distribution Science Association 2020 The Journal of Asian Finance, Economics and Busine Vol.7 No.9

In recent years, the quality of auditing human resources in domestic auditing firms in Hanoi has certain limitations in which professional skills of auditors have not been given adequate attention. The number of customers at local auditing firms is forecast to increase gradually. Therefore, the quantity and quality of auditors need to be improved to meet requirements of the workload. Data for this research were collected through surveying 120 customers of domestic auditing firms in Hanoi on the 5-point Likert scale. Based on the collected data, we employ both qualitative and quantitative methodology along with some tools such as descriptive statistics, Cronbach's Alpha, T-test and ANOVA to analysis, evaluate and measure the professional skills of auditors in local auditing firms in Hanoi. The results show that the professional skills of auditors in auditing firms include 17 attributes. The majority of respondents show appreciation for the professionalism and professional competence of auditors, while, they think that critical thinking skills and creative thinking skills are still limited and need to be improved. These findings, not only help auditors to improve themselves, but also provide solutions for managers of domestic auditing firms in Hanoi to enhance quality of audited human resources.

베트남의 1986년도 정치경제 개혁, 즉 도어머이(Doi Moi)는 베트남의 경제를 개방적 사회주의경제로 전환시켰으며, 이를 계기로 베트남 경제는 획기적으로 근대화되었다. 그러나 이 과정에서 급속한 도시화는 도농 간 불균형을 가져왔으며, 이 도농 간 격차를 줄이기 위해 베트남 정부는 2006년에 새농촌개발(NRD) 프로그램을 도입하기에 이르렀다. 이 프로그램은 농촌 지역의 사회기반시설의 확충과 생활환경의 개선, 생산 활동의 종합적 발전, 소득증대, 농민들의 육체적ㆍ정신적 건강 증진 등을 목표로 하고 있었다. 이 논문의 주된 목적은 NRD 프로그램의 시행이 NRD의 궁극적 목적 중 하나인 농가소득 증대에 미치는 영향에 대한 과학적 증거를 제시하는 데 있다. 또한 이와 더불어 새마을운동의 시범사업을 실시한 지역과 그렇지 않은 지역 간에 소득 증대에서 차이가 있는가를 다중회귀분석을 통해 밝혀보고자 한다. 분석 결과는 NRD의 시행이 상당히 긍정적 결과를 가져왔으며 코민 수준에서 농가소득 증대와 생활환경의 개선에 중요한 영향을 미쳤다는 것을 보여주었다. 또한 도로 건설, 전기 도입, 주민 역량 강화, 제도의 발전 등이 농가소득 증대에 큰 영향을 미쳤음을 확인했다. 회귀분석의 결과는 또한 새마을 사업을 시행하고 있는 코뮌들이 그렇지 않은 코뮌에 비해 연소득이 1200만 동(미화530달러) 더 많다(또는 41.8% 더 높다)는 것을 보여주었다. The economic and political reform of Vietnam in 1986 (the Doi Moi) has transformed its economy positively and significantly into an open socialist-oriented market economy. This caused a dramatic change of Vietnam’s economy towards modernization. However, the urbanization process created an unbalanced development between the urban and rural regions. To solve the gaps between these regions, the government of Vietnam firstly introduced the New Rural Development (NRD) program in 2006 to encourage and mobilize a revolutionary and campaign to improve local infrastructure, living condition, comprehensive development of related-production activities in rural regions, as well as increase income, and improve physical and mental health of people living in rural communities. One of the main purposes of this research paper is aimed at providing a scientific evidence for justifying whether the NRD implementation could have an impact on rural households’ income, one of the ultimate goals of the NRD, and examining the difference of incomes between Saemaul Undong (SU)-piloted provinces with the other provinces by employing a multiple regression model. The analysis results show that the NRD implementation has shown positive results and significant impacts on increasing rural households’ income and improving living conditions at the communal levels. Criteria such as road development, access to electricity, capacity building, and institutional development have significantly influenced on the households’ income. The regression model also indicates that the communes currently implementing SU pilots have a better annual income of 12 million VND (~US$ 530) or 41.8% higher than the other communes.

This study describes the preparation and characterization of a green and safe membrane based on a natural polymer for metal adsorption. Natural rubber-grafted-(2-hydroxyethyl methacrylate) with a special nanostructure was synthesized by graft copolymerization of 2-hydroxyethyl methacrylate (HEMA) onto the surface of natural rubber (NR) particles using tert-butylhydroperoxide/tetraethylenepentamine as initiators. Optimal conditions for achieving high conversion and grafting efficiency were identified. Characterization of the as-synthesized samples was performed using Fourier-transform infrared spectroscopy, transmission electron microscopy, thermogravimetric analysis, tensile measurement, swelling degree determination, and cytotoxicity testing. The results revealed that HEMA formed a nanoscale matrix surrounding NR particles, which improved the tensile strength, thermal resistance, and swelling degree of the as-prepared samples. Cytotoxicity testing demonstrated that the membrane was safe for human use, as it did not exhibit toxicity to Vero cells at concentrations up to 1024 μg/mL. Furthermore, the membrane displayed a high adsorption capacity toward Fe3+ and was well described by Koble-Corrigan isotherm model and the first–second-order kinetic equation. Moreover, the membrane demonstrated excellent recyclability maintaining its adsorption ability towards Fe3+ ions over five consecutive cycles. Overall, these findings may recommend the NR-HEMA membrane as a promising candidate for metal removal applications.

Thi Thu Cuc NGUYEN,My Hanh HO 한국유통과학회 2021 The Journal of Asian Finance, Economics and Busine Vol.8 No.7

Nowadays, small- and medium-sized enterprises (SMEs) are placed among the key components of the economy in both developed and developing countries. They are internationally known as the driving force based on their enormous contributions to Gross Domestic Product (GDP) and generating new employment. They are generally presumed as the leader of environmental sustainability, economic prosperity, and innovation, particularly for the economy of developing countries such as Vietnam. However, SMEs have difficulty in raising capital, as well as access to credit. One of the reasons is that there are inadequacies in accounting information quality in SMEs as well as the provision of accounting information and accounting information confidentiality. The main objective of this study was to identify, evaluate, and measure the attributes of accounting information quality of SMEs in Hanoi. The study was based on a field survey using a semi-structured questionnaire on a sample of 150 accountants. The study has identified and measured six (6) attributes of accounting information quality of SMEs that have great effects on accountants. There is, statistically, no significant difference in the level of accounting information quality of SMEs in Hanoi from these different business areas. There is no, statistically, significant difference in the level of accounting information quality of SMEs in Hanoi between the mentioned three groups of the job description. Based on the findings, some recommendations are given for SMEs to improve accounting information quality.
