Purpose: Predicting the financial distress distribution of an enterprise is important to warn enterprises about their future. Predicting the possibility of financial distress helps companies have action plans to avoid the possibility of bankruptcy. In this study, the author conducted a forecast of the financial distress distribution of enterprises. Research design, data and methodology: The forecasting method is based on Logit and Discriminant analysis models. The data was collected from companies listed on Vietnam Stock Exchange from 2012 to 2020. In which there are both companies suffer from financial distress and non-financial distress. Results: The forecast analysis results show that the Logistic model has better predictability than the Discriminant analysis model. At the same time, the results also indicate three main factors affecting the financial distress of enterprises at all three research stages: (1) Liquidity, (2) Interest payment, and (3) firm size. In addition, at each stage, the impact of factors on financial distress differs. Conclusions: From the results of this study, the author also made several recommendations to help companies better control company operations to avoid falling into financial distress. Adjustments to current assets, debt, and company expansion considerations are the most important factors for companies.

Purpose - Vietnam is among the fastest growing digital economies in the Southeast Asian region, and has made enormous efforts to adopt digital measures to facilitate trade. The paper aims to assess Vietnam’s performance of digital trade facilitation and estimate the impact of digital trade facilitation on Vietnam’s exports to the Association of Southeast Asian Nations (ASEAN). Design/Methodology/Approach - Vietnam’s implementation of digital trade facilitation is assessed through a constructed framework based on two groups of indicators, including Information Availability and Formalities Automation extracted from the OECD Trade Facilitation database. Further, a gravity model was adopted to estimate the impact of digital trade facilitation on Vietnam’s exports. Findings - The results show that Vietnam performs a slightly better than the average level of ASEAN countries. However, Vietnam’s implementation of digital trade facilitation tends to be ỉmproving at a slower rate than other ASEAN countries’ implementations, as well as the country’s overall implementation of other trade facilitation. The paper is among leading studies to quantify the impact of digital trade facilitation on Vietnam’s exports to ASEAN countries, and finds that if Vietnam and ASEAN countries increase trade facilitation through Information Availability measures by 1%, Vietnam’s exports will increase more than proportionately by 1.29% and 1.01%, respectively. Meanwhile, the digitalization of trade formalities so far has had no effect on Vietnam’s exports to this region. Research Implications - Vietnam should place priority on enhancing automation in trade-related administrative procedures, especially in customs procedures. Furthermore, it should pay more attention to promote the electronic publication of trade-related information, enhance the transparency of government policymaking, and increase the quality of enquiry points.

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.

몇 가지 다른 폴리아스팔트아미드 유도체를 아스팔트산의 열축합 고분자인 폴리숙신이미드의 에탄올아민과 또 다른 아민 화합물을 사용한 연속적인 개환 아미노분해 반응으로부터 제조하였다. 합성한 폴리아스팔트아미드 고분자의 화학적 구조를 NMR과 FTIR 분광기를 사용하여 확인하였다. 물리적 가교제 및 접착물성 증진제로서 탄닌산과 위에서 합성한 고분자를 수용액 상에서 여러 다른 중량비로 혼합함으로써 두 성분간의 컴플렉스 젤을 제조하였다. 이들 컴플렉스 젤 형성 거동과 제조된 젤 시료의 서로 다른 기질과 조건에 대한 접착 물성을 비교 검토하였다. 한편, 열중량분석과 FTIR을 이용하여 재료의 열분해 특성과 두 성분간의 분자간 상호작용을 고찰하였다. 성분 간 강한 수소결합에 기인한 이들 생체적합성 폴리아미노산 고분자와 탄닌산의 컴플렉스 젤은 신규 생체의료용 및 산업용 접착소재로서 응용 가능할 것으로 기대된다. Several polyaspartamide copolymers were prepared from polysuccinimide, the thermal polycondensation product of aspartic acid, via a successive ring-opening reaction using ethanolamine and other amine nucleophiles. 1H NMR and FTIR spectroscopy were used to identify the chemical structure of the polyaspartamide copolymers. A complex gel was formed upon adding tannic acid (TA) as both a physical cross-linker and adhesive enhancer to the polymer solution at different compositions in an aqueous system. The complexation behavior was investigated and the adhesive properties of the resulting complex gels were measured and compared each other. The thermal properties of the complex gels were also investigated using thermogravimetric analysis. Strong multiple hydrogen-bonding interactions between TA and the polymer chain are considered to be responsible for the formation of these biocompatible complex gels, which have potential use as novel biocompatible adhesive materials.

This study aims to examine and measure the impact of capital structure on the profitability of companies in emerging markets. The research sample includes eighteen rubber companies listed on the Vietnam stock exchange from 2015–2019. After collecting the research data, it was imported into excel to calculate the criteria for the research model. By using Stata 16 software, the study selected a data processing model and evaluated the relevance of the regression analysis model. The research results show that the profitability of listed rubber companies in Vietnam (measured by return on equity (ROE) has a positive relationship with the debt-to-asset ratio but has a negative relationship with the long-term debt-to-asset ratio. The results also show a positive impact of firm size and revenue growth on profitability while liquidity and the ratio of tangible fixed assets to total assets do not affect significantly. These results are consistent with most of the previously published studies. However, in contrast to many previous studies, our study shows that the long-term debt-to-assets ratio has a negative effect on profitability while the debt-to-asset ratio has a positive effect. This is entirely consistent with the characteristics of long-term debt use in emerging markets.

<P><B>Abstract</B></P> <P>In this study, Fe-nano zeolite was applied to the removal of ortho, meta and para-nitrophenols to evaluate its potential applications as an effective adsorbent. Scanning electron microscopy, Fourier-transformed infrared spectroscopy, and gas adsorption analysis were used to compare the advanced properties of Fe-nano zeolite with those of commercial activated carbon (AC). The Fe-nano zeolite with a greatly improved surface area was particularly effective in the removal of the nitrophenols. The maximum adsorption capacity of <I>m</I>-, <I>o</I>- and <I>p</I>-nitrophenol were 168.7, 193.9 and 223.1mg/g, respectively. These adsorbents were applied to the remediation of wastewater containing high <I>p</I>-nitrophenol concentration of 380mg/L. The results revealed 92.8% removal efficiency of <I>p</I>-nitrophenol from wastewater by Fe-nano zeolite, which is much higher than those AC (56.5%). The regeneration characteristics of the <I>p</I>-nitrophenol-loaded adsorbent were analyzed. Even after 15 adsorption-desorption cycles, the removal efficiencies of <I>p</I>-nitrophenol by Fe-nano zeolite and AC were 78.6 and 57.9%, respectively. The required adsorption cost for the treatment of 1000kg wastewater containing 380mg/L of <I>p</I>-nitrophenol using Fe-nano zeolite was 67.6% lower than that using AC. Based on these results, Fe-nano zeolite can be used as economic and effective adsorbent for removal of nitrophenols from wastewater.</P> <P><B>Highlights</B></P> <P> <UL> <LI> Fe-nano zeolite is an effective adsorbent for nitrophenol removal. </LI> <LI> Adsorption capacity of <I>m</I>-, <I>o</I>- and <I>p</I>-nitrophenol were 168.7, 193.9 and 223.1mg/g, respectively. </LI> <LI> Removal efficiency from wastewater by Fe-nano zeolite (92.8%) was much higher than AC (56.5%). </LI> <LI> Adsorption cost for treatment of 1000kg wastewater by Fe-nano zeolite was 67.6% lower than AC. </LI> </UL> </P> <P><B>Graphical abstract</B></P> <P>[DISPLAY OMISSION]</P>
