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.

In this study, graphene oxide (GO) was synthesized by the improved Hummers’ method. The degree of oxidation from graphite (Gi) to GO was determined through interlayer spacing calculated from X–ray diffraction. Besides, the effect of KMnO4:Gi ratios (X1), H2SO4 volume (X2), oxidation temperature (X3), oxidation time of stage 1 (X4), and oxidation time of stage 2 (X5) was screened by the Plackett–Burman model. The simultaneous impact of three factors that influenced the degree of oxidation (X1, X2, and X3) was studied by the Box–Behnken experimental model of response surface methodology to achieve suitable conditions for the GO synthesis process. The characterization of GO product was investigated via the modern analytical methods: X-ray diffraction, Raman spectroscopy, Fourier transform infrared spectroscopy, UV–Vis spectroscopy, field emission scanning electron microscopy, transmission electron microscopy, and atomic force microscopy. In addition, the study was also carried out on a pilot scale for orientation in industrial application with the yield of 14 g/batch.

2P-388 Understanding the Electrochemical Behavior of Tin-based Alloy Anode Materials for Magnesium Ion Batteries

( Nguyen Thi Huong Giang ),( Nguyen Dan Thien ),송승완 한국공업화학회 2017 한국공업화학회 연구논문 초록집 Vol.2017 No.1

Rechargeable magnesium battery is a potential candidate as an alternative to lithium-ion battery for use in energy storage systems due to low cost, high specific volumetric capacity (3833 mAh/㎤) and reasonable gravimetric capacity (2205 mAh/g). However, the development of Mg cells still faces many challenges. The formation of electrochemically inactive surface blocking layer on Mg metal anode prohibits its reversible reaction in electrolyte containing commercially available magnesium salts such as Mg(TFSI)₂ or Mg(ClO₄)₂ in room temperature polar aprotic solvents. To mitigate those issues, insertiontype anode materials have been introduced as alternatives to Mg metal. Our recent works have demonstrated that tin-based materials have a high potential for use as anode active materials in Mg-ion batteries at room temperature. In this presentation, we will report the synthesis and characterization tin-alloy materials, and their electrochemical behavior in room temperature Mg-ion cells.

아시아는 현재 세계에서 가장 역동적인 경제지역으로 손꼽히고 있으며, 세계 경제의 확장 및 발전에 있어 중추적인 역할을 맡고 있다는 점은 주지의 사실이다. 이러한 배경 속에서 지역경제협력의 촉진을 목적으로 하여 아시아 지역에서는 오늘도 수많은 양자 및 다자간 무역 협상이 이루어지고 있다. 아시아 지역의 핵심 구성원 중 하나인 베트남 역시 동남아시아 및 동아시아 국가들과의 경제통합노력에 활발히 참여하고 있으며, 구체적인 방안으로 베트남 내의 외국인 투자에 주된 장벽으로 간주되던 베트남 경제 분야의 법제도 개정에 박차를 가하고 있다. 베트남 정부는 관료주의적 절차의 철폐 및 외국인 투자자에 대한 자율권 확대 등 경제 분야의 법제도의 근본적인 변화를 모색하고 있으며, 이를 통하여 외국인투자자 및 외국인투자자본에 대한 우호적 환경이 마련될 것으로 전망된다. It is well-established fact that Asia is one of the world"s most dynamic economies and growingly plays pivotal role in the expansion and development of the world"s economy. Given this fact, a series of negotiating forums is established in order to promote the intraregional economic cooperation through bilateral and multilateral trade agreements concluded between the governments concerned. As a key player of regional arena, Vietnam has launched vigorous attempts to integrate tightly with other regional economies under specific attention to South East Asia and East Asia countries. One of the practical efforts is to amend the current legal framework, which has been long believed as the major barrier to foreign investors. Through fundamental changes such as cutting off bureaucratic procedures and giving enterprises with greater freedom to do a business, the adjusted Law on Enterprises is supposed to offer favorable environment to foreign investment capitals and contributes to the Asian economy integration in the long term. More important, this expresses the Vietnamese government"s strong commitment to speed up economic integration process within East Asian countries.

Foreign Direct Investment -Small and Medium Enterprises Linkages and Global Value Chain Participation: Evidence from Vietnam

NGUYEN, Thi Minh Thu,NGUYEN, Thi Tuong Anh,NGUYEN, Thi Thuy Vinh,PHAM, Huong Giang Korea Distribution Science Association 2021 The Journal of Asian Finance, Economics and Busine Vol.8 No.3

Using a multinomial logit model with the panel-data set of Vietnam manufacturing firms, this paper investigates the impacts of foreign direct investment (FDI) - small and medium enterprises (SMEs) linkages and other factors on SMEs' participation in the global value chain (GVC). We consider GVC firms are those engaging in any of the three modes including (i) using domestic inputs to export (D2E), (ii) using imported inputs to produce for the domestic market (I2P), (iii) using imported inputs to export (I2E). We discover that FDI-SME linkages statistically encourage Vietnamese SMEs to integrate into the GVC via I2P and I2E, while no statistical association between FDI-SME linkage and D2E participation is found. GVCs participation likelihood is also positively correlated with the introduction of new product introduction. The establishment of firms' production facilities in industrial zones and foreign ownership are both reported to be significantly decisive factors to SMEs' decisions on GVC participation. Besides, there is a strong association between firms' attributes, i.e. employment, capital intensity as well as financial access, and their participation in the GVC. Local governance quality (proxied by the Provincial Competitiveness Index) and the share of skilled labor at the province-level can facilitate firms' integration into GVCs, while greater market concentration may be a hurdle to such potential.

The objectives of the present study were to evaluate theanatomic localization of porcine reproductive andrespiratory syndrome virus (PRRSV) in naturally infectedpigs and to determine whether oral fluid could be used todetect the virus in infected animals. Two sows, seven2-month-old grower pigs, and 70 6-month-old gilts wereincluded in this study. PRRSV in sera and oral fluid wereidentified by nested reverse transcription PCR (nRT-PCR)while lung, tonsil, and tissue associated with oral cavity weresubjected to nRT-PCR, immunohistochemistry, and in situhybridization. In sows, PRRSV was identified in oral fluidand tonsils. PRRSV was also detected in oral fluid, tonsils,salivary glands, oral mucosa, and lungs of all seven growerpigs. However, viremia was observed in only two growerpigs. Double staining revealed that PRRSV was distributedin macrophages within and adjacent to the tonsillar cryptepithelium. In gilts, the North American type PRRSV fieldstrain was detected 3 to 8 weeks after introducing theseanimals onto the farm. These results confirm previousfindings that PRRSV primarily replicates in tonsils and isthen shed into oral fluid. Therefore, oral fluid sampling maybe effective for the surveillance of PRRSV in breeding herds.

Studies have shown that smoking is a learnt behavior, often initiated during adolescence. This paper aims to describe tobacco-related knowledge, attitude and associations among school adolescents aged 13-15 with exposure to anti-smoking information. Using data from the Global Youth Tobacco Survey (GYTS) in Viet Nam, 2014, knowledge was measured through 4 questions about tobacco use, and attitude was assessed through 3 questions on personal, social and environmental aspects. Students giving most anti-tobacco responses to all questions were considered as having correct knowledge or appropriate attitude or both. Access to anti-smoking information was determined by exposure to any media messages on tobacco control during the past 30 days and teaching in school about the danger of tobacco use during the past 12 months. A substantial percentage of students thought that being near others who smoke might be harmful to them and smoking is harmful to health (89.4% and 89.6% respectively). However, only 46.4% reported that it is definitely difficult to quit smoking and 66.9% thought that smoking for only 1 or 2 years, once stopped, is harmful to health. Slightly more than half of the respondents reported appropriate attitude that young smokers have fewer friends than others and smoking makes them less attractive and less comfortable at social events. Noticing anti-smoking messages in the media together with having lessons in school about the dangers of tobacco substantially increased the likelihood of having correct knowledge, appropriate attitude and both. Despite relatively high awareness about smoking harms, effective educational communication is still highly needed to improve the level of comprehensive knowledge and an appropriate attitude regarding tobacco use.

GCC2Verilog Compiler Toolset for Complete Translation of C Programming Language into Verilog HDL

Giang Nguyen Thi Huong,김선욱 한국전자통신연구원 2011 ETRI Journal Vol.33 No.5

Reconfigurable computing using a field-programmable gate-array (FPGA) device has become a promising solution in system design because of its power efficiency and design flexibility. To bring the benefit of FPGA to many application programmers, there has been intensive research about automatic translation from high-level programming languages (HLL) such as C and C++ into hardware. However, the large gap of syntaxes and semantics between hardware and software programming makes the translation challenging. In this paper, we introduce a new approach for the translation by using the widely used GCC compiler. By simply adding a hardware description language (HDL) backend to the existing state-of-the-art compiler, we could minimize an effort to implement the translator while supporting full features of HLL in the HLL-to-HDL translation and providing high performance. Our translator, called GCC2Verilog, was implemented as the GCC's cross compiler targeting at FPGAs instead of microprocessor architectures. Our experiment shows that we could achieve a speedup of up to 34 times and 17 times on average with 4-port memory over PICO microprocessor execution in selected EEMBC benchmarks.

Trong Luan NGUYEN,Trung Hau NGUYEN,Thao Vy THACH,Doan Vy TRAN,Nguyen Huong Giang HOANG,Ngoc Phuong Trang PHAM 한국유통과학회 2022 The Journal of Asian Finance, Economics and Busine Vol.9 No.1

Entrepreneurs are valuable assets for any country. Rather than being confronted with new obstacles, they should be fostered and nurtured. Entrepreneurial firms have the power to influence how we live and work, in addition to producing jobs and contributing to economic progress. Entrepreneurs have the ability to change the world by creating diversified skill sets and profitable businesses that are vital to the advancement of our economies. How does one go about being a successful business, though? More resources are believed to be needed to create entrepreneurial environments in higher education that foster progressive ideas and innovation while also providing students with the practical knowledge and skills they need to navigate the troublesome, difficult, and uncertain situations that come with owning a business. This article will outline the scales of components from which to measure variables impacting universities’ ability to encourage entrepreneurial behavior among students, based on the aforementioned significance of universities. This article is based on a survey of 507 students from different universities and backgrounds in Vietnam. The research methods used are Cronbach’s alpha test and Structural Equation Modeling. From the research results, it can be seen that the university’s environment plays a significant role in fostering entrepreneurial behavior among students.
