Факторы, оказывающие воздействие на кредитование малых и средних предприятий во Вьетнаме

Article retractedThe difficulty in accessing loans is one of the major barriers to the development of small and medium enterprises (SMEs) in Vietnam. Low accessibility to capital forces SMEs to spend both official and unofficial costs in order to obtain loans, and/or to access the unofficial market at higher interest rates, thereby increasing cost of production of enterprises. Studies suggest that the determinants of bank loan processing through which small and medium enterprises can access official loans include: characteristics of enterprises; indicators, reflecting the performance of enterprises; characteristics of loans; characteristics of enterprises, enterprise owners; geographical position of enterprises; the creditworthiness of enterprises and the role of the network.Purpose of the study. The aim of this paper is the quantitative analysis of the factors, affecting accessibility to credit capital of small and medium enterprises in Vietnam.Materials and methods. This study was conducted on the basis of a survey in December 2017. The survey includes 301 enterprises in Hanoi city. Selected enterprises are also enterprises, surveyed in the annual enterprise survey by the General Statistics Office of Vietnam. This paper uses the Probit and Logit regression approach to estimate the impact of factors, affecting the disbursement probability of a loan of an enterprise. The number of SMEs accounts for 56.69% of the samples. The number of enterprises, applying for a bank loan accounts for 58.4% of the total samples, of which the percentage of disbursed loans for SMEs accounts for only 47.3%. For enterprises without a bank loan, eliminating the reasons for the lack of demand and unwish to be in debt, the main reasons not to access bank loans are high interest rates, complicated loan procedures and insufficient collateral.Results. The results obtained from the Logistic and Probit models show that the estimated coefficients are statistically significant, affecting the probability of taking a business loan, accepted by financial institutions. Although the coefficients, estimated from Logistics model are larger than those estimated from the Probit model, the estimated results show that the direction of impact of the variables in two estimation techniques gives quite similar results.Conclusion. Based on the results of this study, the Government of Vietnam should implement policies to support SMEs in the direction of improving their access to capital. The credit institutions should design products and services suitable to the characteristics of SMEs in Vietnam.Статья отозванаТрудность в доступе к кредитам является одним из основных препятствий на пути развития малых и средних предприятий (МСП) во Вьетнаме. Низкая доступность капитала вынуждает МСП тратить как официальные, так и неофициальные расходы на получение кредитов и/или на доступ к неофициальному рынку с более высокими процентными ставками, тем самым увеличивая стоимость производства предприятий. Исследования показывают, что детерминанты обработки банковских кредитов, через которые малые и средние предприятия могут получить доступ к официальным кредитам, включают: характеристики предприятий; показатели, отражающие показатели деятельности предприятий; характеристики кредитов; характеристики предприятий, владельцев предприятий; географическое положение предприятий; кредитоспособность предприятий и роль сети.Цель исследования. Целью настоящей работы является количественный анализ факторов, оказывающие воздействие на кредитование малых и средних предприятий во Вьетнаме.Материалы и методы. Для достижения поставленной цели статья была проведена на основе опроса в декабре 2017 года. В опросах приняли участие 301 предприятие в городе Ханой. Данные предприятия также являются предприятиями, опрошенными в ежегодном обследовании предприятий Главным статистическим управлением Вьетнама. В этой статье используется подход регрессии Probit и Logit для оценки влияния факторов, влияющих на вероятность выплаты кредита предприятию. На долю МСП приходится 56,69% образцов. Количество предприятий, обращающихся за банковским кредитом, составляет 58,4% от общего объема выборок, из которых доля выданных кредитов для МСП составляет всего 47,3%. Для предприятий без банковского кредита, устраняя причины отсутствия спроса и не желая быть в долгу, основными причинами не получения банковских кредитов являются высокие процентные ставки, сложные процедуры кредитования и недостаточное обеспечение.Результат. Результаты, полученные в модели Logistic и Probit, показывают, что оценочные коэффициенты являются статистически значимыми, что влияет на вероятность принятия бизнес-кредита, принятого финансовыми учреждениями. Хотя коэффициенты, оцененные по модели логистики, больше, чем оцененные по модели Пробита, оценочные результаты показывают, что направление воздействия переменных в двух методах оценки дает весьма схожие результаты.Заключение. Исходя из результатов этого исследования, правительство Вьетнама должно осуществлять политику поддержки МСП в направлении улучшения их доступа к капиталу. Кредитные учреждения должны проектировать товары и услуги, соответствующие характеристикам МСП во Вьетнаме

Rheological properties of emulsion of crude oil and water

In the paper the rheological properties of crude oil of White Tiger oil-field (Vietnam) and its emulsion with sea-water, including measurement results and analytical approximation formulae for wide range of pressure, temperature and water concentration, are presented. As it is known, the crude oil of White Tiger oil-field is a high-paraffin and high-viscous oil. At the low temperature (T ≤ 40°C) it behaves as non-Newtonian fluid of Bingham-Shvedov group. Therefore, beside the effective viscosity, the effective dynamic shear stress is also measured and approximated. The rheological properties of crude oil and emulsion of crude oil and water are also measured and approximated for the case when the mixture contains 0.1% chemical reagent ES-3363

Health and safety management practices of contractors in South East Asia: A multi country study of Cambodia, Vietnam, and Malaysia

© 2017 Elsevier Ltd The construction sector is notorious for accounting for numerous occupational deaths, injuries and illnesses in many countries. In emerging economies this situation could be direr, and health and safety (H&S) management by contractors is important to tackling this. This study investigated the H&S management practices of contractors in three South East Asian countries (Malaysia, Vietnam, and Cambodia) with the view to highlighting implementation issues. A questionnaire instrument containing 40 H&S management practices was administered to contractors in the three countries. Analysis of the data revealed that in each of the three countries there are at least seven practices that are not commonly implemented by contractors. Whilst the study further suggests this to be acute in Malaysia and Cambodia, it also elucidates that the apparent situation could be due to inter alia: a significantly greater proportion of the contractors in the Malaysia sample being micro size firms; and also the effect of two national occupational H&S programmes implemented in Vietnam from 2006 to 2015. Overall, the findings offer an opportunity for contractors and key industry stakeholders (e.g. state authorities) to reflect on their approach/initiatives to improving H&S management in construction. Further studies which could offer additional empirical realities are also suggested

Emerging Role of Circulating Tumor Cells in Gastric Cancer

With over 1 million incidence cases and more than 780,000 deaths in 2018, gastric cancer (GC) was ranked as the 5th most common cancer and the 3rd leading cause of cancer deaths worldwide. Though several biomarkers, including carcinoembryonic antigen (CEA), cancer antigen 19-9 (CA19-9), and cancer antigen 72-4 (CA72-4), have been identified, their diagnostic accuracies were modest. Circulating tumor cells (CTCs), cells derived from tumors and present in body fluids, have recently emerged as promising biomarkers, diagnostically and prognostically, of cancers, including GC. In this review, we present the landscape of CTCs from migration, to the presence in circulation, biologic properties, and morphologic heterogeneities. We evaluated clinical implications of CTCs in GC patients, including diagnosis, prognosis, and therapeutic management, as well as their application in immunotherapy. On the one hand, major challenges in using CTCs in GC were analyzed, from the differences of cut-off values of CTC positivity, to techniques used for sampling, storage conditions, and CTC molecular markers, as well as the unavailability of relevant enrichment and detection techniques. On the other hand, we discussed future perspectives of using CTCs in GC management and research, including the use of circulating tumor microembolies; of CTC checkpoint blockade in immunotherapy; and of organoid models. Despite the fact that there are remaining challenges in techniques, CTCs have potential as novel biomarkers and/or a non-invasive method for diagnostics, prognostics, and treatment monitoring of GC, particularly in the era of precision medicine

A modified Sequential Organ Failure Assessment score for dengue: development, evaluation and proposal for use in clinical trials

Background Dengue is a neglected tropical disease, for which no therapeutic agents have shown clinical efficacy to date. Clinical trials have used strikingly variable clinical endpoints, which hampers reproducibility and comparability of findings. We investigated a delta modified Sequential Organ Failure Assessment (delta mSOFA) score as a uniform composite clinical endpoint for use in clinical trials investigating therapeutics for moderate and severe dengue. Methods We developed a modified SOFA score for dengue, measured and evaluated its performance at baseline and 48 h after enrolment in a prospective observational cohort of 124 adults admitted to a tertiary referral hospital in Vietnam with dengue shock. The modified SOFA score included pulse pressure in the cardiovascular component. Binary logistic regression, cox proportional hazard and linear regression models were used to estimate association between mSOFA, delta mSOFA and clinical outcomes. Results The analysis included 124 adults with dengue shock. 29 (23.4%) patients required ICU admission for organ support or due to persistent haemodynamic instability: 9/124 (7.3%) required mechanical ventilation, 8/124 (6.5%) required vasopressors, 6/124 (4.8%) required haemofiltration and 5/124 (4.0%) patients died. In univariate analyses, higher baseline and delta (48 h) mSOFA score for dengue were associated with admission to ICU, requirement for organ support and mortality, duration of ICU and hospital admission and IV fluid use. Conclusions The baseline and delta mSOFA scores for dengue performed well to discriminate patients with dengue shock by clinical outcomes, including duration of ICU and hospital admission, requirement for organ support and death. We plan to use delta mSOFA as the primary endpoint in an upcoming host-directed therapeutic trial and investigate the performance of this score in other phenotypes of severe dengue in adults and children

Excess body weight and age associated with the carriage of fluoroquinolone and third-generation cephalosporin resistance genes in commensal Escherichia coli from a cohort of urban Vietnamese children.

PURPOSE: Antimicrobial-resistant bacterial infections in low- and middle-income countries (LMICs) are a well-established global health issue. We aimed to assess the prevalence of and epidemiological factors associated with the carriage of ciprofloxacin- and ceftriaxone-resistant Escherichia coli and associated resistance genes in a cohort of 498 healthy children residing in urban Vietnam. METHODOLOGY: We cultured rectal swabs onto MacConkey agar supplemented with resistant concentrations of ciprofloxacin and ceftriaxone. Additionally, we screened meta-E. coli populations by conventional PCR to detect plasmid-mediated quinolone resistance (PMQR)- and extended-spectrum β-lactamase (ESBL)-encoding genes. We measured the associations between phenotypic/genotypic resistance and demographic characteristics using logistic regression.Results/Key findings. Ciprofloxacin- and ceftriaxone-resistant E. coli were cultured from the faecal samples of 67.7 % (337/498) and 80.3 % (400/498) of children, respectively. The prevalence of any associated resistance marker in the individual samples was 86.7 % (432/498) for PMQR genes and 90.6 % (451/498) for β-lactamase genes. Overweight children were significantly more likely to carry qnr genes than children with lower weight-for-height z-scores [odds ratios (OR): 1.24; 95 % confidence interval (CI): 10.5-1.48 for each unit increase in weight for height; P=0.01]. Additionally, younger children were significantly more likely to carry ESBL CTX-M genes than older children (OR: 0.97, 95 % CI: 0.94-0.99 for each additional year, P=0.01). CONCLUSION: The carriage of genotypic and phenotypic antimicrobial resistance is highly prevalent among E. coli in healthy children in the community in Vietnam. Future investigations on the carriage of antimicrobial resistant organisms in LMICs should focus on the progression of carriage from birth and structure of the microbiome in obesity

An Outbreak of Severe Infections with Community-Acquired MRSA Carrying the Panton-Valentine Leukocidin Following Vaccination

Background: Infections with community-acquired methicillin-resistant Staphylococcus aureus (CA-MRSA) are emerging worldwide. We investigated an outbreak of severe CA-MRSA infections in children following out-patient vaccination. Methods and Findings: We carried out a field investigation after adverse events following immunization (AEFI) were reported. We reviewed the clinical data from all cases. S. aureus recovered from skin infections and from nasal and throat swabs were analyzed by pulse-field gel electrophoresis, multi locus sequence typing, PCR and microarray. In May 2006, nine children presented with AEFI, ranging from fatal toxic shock syndrome, necrotizing soft tissue infection, purulent abscesses, to fever with rash. All had received a vaccination injection in different health centres in one District of Ho Chi Minh City. Eight children had been vaccinated by the same health care worker (HCW). Deficiencies in vaccine quality, storage practices, or preparation and delivery were not found. Infection control practices were insufficient. CA-MRSA was cultured in four children and from nasal and throat swabs from the HCW. Strains from children and HCW were indistinguishable. All carried the Panton-Valentine leukocidine (PVL), the staphylococcal enterotoxin B gene, the gene complex for staphylococcal-cassette-chromosome mec type V, and were sequence type 59. Strain HCM3A is epidemiologically unrelated to a strain of ST59 prevalent in the USA, althoughthey belong to the same lineage. Conclusions. We describe an outbreak of infections with CA-MRSA in children, transmitted by an asymptomatic colonized HCW during immunization injection. Consistent adherence to injection practice guidelines is needed to prevent CA-MRSA transmission in both in- and outpatient settings
