- Tác giả: Hồ Dũng Mạnh và Cộng sự.

- Tên tạp chí: Journal of Applied Toxicology

- ABSTRACT: The absorption of cadmium(Cd)may lead to Cd-related diseases such as renal tubular dysfunction and bone disease, and it is known to take around 10–30 years to reduce Cd concentrations to half their original levels. Urinary β2-microglobulin (β2-MG), N-acetyl-β-D-glucosaminidase (NAG), protein, glucose and albumin were used as indicators of renal dysfunction caused by Cd exposure. Our previous study found that urinary Cd concentrations had increased recently and that age was more strongly associated with urinary β2-MG concentration than recent Cd body burden. Therefore, the purpose of the present study was to investigate the effect of aging on Cd concentrations and renal dysfunction. The Cd, β2-MG, NAG, protein, glucose and albumin concentrations in the urine of 40 Japanese subjects (20 females and 20 males) environmentally exposed to Cd were collected. They lived in the Kakehashi River basin and were divided into three age categories: 50–69, 70–79 and 80–99 years. Significant differences in urinary Cd and β2-MG concentrations were found among age groups, with urinary Cd levels tending to increase with age in both sexes. No significant correlations were found between urinary Cd and any indicators of renal dysfunction. The correlation between age, Cd and indicators of renal dysfunction was observed more clearly in females than in males. Age is more strongly correlated with indicators of renal dysfunction than Cd body burden. Copyright © 2017 John Wiley & Sons, Ltd.

- Tên tạp chí: Science of the Total Environment

- ABSTRACT: Although Vietnam's massive herbicide exposure in 1960s and 1970swas clearly injurious to health, not all causal relationships have been clarified. We therefore explored associations among dioxins, steroid hormones, age and prostate cancer risk in men.Wecompared erumlevels of dioxin, steroid hormones and prostate specific antigen (PSA) in men aged 56–81 years from herbicide-exposed hotspots (n=50)with those fromnon-sprayed regions (n=48).Mean serum levels of dioxin congeners in the hotspot group were 1.5–11.3 times higher than the nonsprayed group depending on specific compound. Levels of estosterone, estradiol and 3β-hydroxysteroid dehydrogenase (3β-HSD) activity in the hotspot group were also significantly higher than in non-sprayed group. Estradiol levels were significantly related to levels of several specific dioxin derivatives in both group. Significant positive correlations were also found between DHT and 1234678-HpCDD or 1234678-HpCDF; and between 3β-HSD activity and 123678-HxCDD, 123478-HxCDF, 123678-HxCDF, or xCB#169.

- Tác giả: Cao Văn Dư và Cộng sự.

- Tên tạp chí: Journal of Environment Science and Health, Part A- ISSN: 1093-4529 (Print)

- ABSTRACT: In this study, the performance of poly(layered double hydroxides) [poly(LDHs)] beads as an adsorbent for arsenate removal from aqueous solution was investigated. The poly(LDHs) beads were prepared by immobilizing LDHs into spherical alginate/polyvinyl alcohol (PVA)-glutaraldehyde beads (spherical polymer beads). Batch adsorption studies were conducted to assess the effect of contact time, solution pH, initial arsenate oncentrations and co-existing anions on arsenate removal performance. The potential reuse of these poly(LDHs) beads was also investigated. Approximately 79.1 to 91.2% of arsenic was removed from an arsenate solution (50 mg As L¡-1) by poly(LDHs). The adsorption data were well described by the pseudo–second-order kinetics model and the Langmuir isotherm model, and the adsorption capacities of these poly(LDHs) beads at pH 8 were from 1.64 to 1.73 mg As g-1, as calculated from the Langmuir adsorption isotherm. The adsorption ability of the poly(LDHs) beads decreased by approximately 5–6% after 5 adsorption-desorption cycles. Phosphates markedly decreased arsenate removal. The effect of co-existing anions on the adsorption capacity declined in the following order: HPO4 2->> HCO3- > SO4 2- > Cl-. A fixed-bed column study was conducted with real-life arseniccontaining water. The breakthrough time was found to be from 7 to 10 h. Under optimized conditions, the poly(LDHs) removed more than 82% of total arsenic. The results obtained in this study will be useful for further extending the adsorbents to the field scale or for designing pilot plants in future studies. From the viewpoint of environmental riendliness, the poly(LDHs) beads are a potential cost-effective adsorbent for arsenate removal in water treatment.

4. Tên bài báo: The Fuzzy u-Chart for sustainable manufacturing in the Vietnam textile dyeing industry

- Tác giả: Nguyễn Thanh Lâm và Cộng sự.

- Tên tạp chí: JSymmetry 2017, 9(7), 116

- ABSTRACT: The inevitability of measurement errors and/or humans of subjectivity in data collection processes make accumulated data imprecise, and are thus called fuzzy data. To adapt to this fuzzy domain in a manufacturing process, a traditional u control chart for monitoring the average number of nonconformities per unit is required to extend. In this paper, we first generalize the u chart, named fuzzy u-chart, whose control limits are built on the basis of resolution identity, which is a well-known fuzzy set theory. Then, an approach to fuzzy-logic reasoning, incorporating the decision-maker’s varying levels of optimism towards the online process, is proposed to categorize the manufacturing conditions. In addition, we further develop a condition-based classification mechanism, where the process conditions can be discriminated into intermittent states between in-control and out-of-control. As anomalous conditions are monitored to some extent, this condition-based classification mechanism can provide the critical information to deliberate the cost of process   ntervention with respect to the gain of quality improvement. Finally, the proposed fuzzy u-chart is implemented in the Vietnam textile dyeing industry to replace its conventional u-chart. The results demonstrate that the industry can effectively evade unnecessary djustments to its current processes; thus, the industry can substantially reduce its operational cost and potential loss.

- Tác giả: Trần Thanh Tuyền và Cộng sự.

- Tên tạp chí: Neural Computing and Applications; ISSN: 0941-0643; DOI 10.1007/s00521-017-3058-9

- ABSTRACT: Accurately forecasting the demand for international and domestic tourism is a key goal for tourism industry leaders. The purpose of this study is to present more appropriate models for forecasting the demand for tourism in Vietnam. The authors apply GM(1,1), Verhulst, DGM(1,1) and DGM(2,1) to test which concise prediction models can improve the ability to predict the number of tourists visiting this country. In order to guarantee the accuracy of forecasting process, data cover in the period from 2005 through 2013 and are obtained from the official website of VNATR ‘‘Vietnam National Administration of Tourism’’ report. The MAPE, MSE, RMSE andMAD are four important criteria which are used to compare the various forecasting models results. Key findings indicate that the optimal value of GM(1,1), Verhulst, DGM(1,1) can enhance the forecasting results perfectly with minimum predicted errors. In the case of the tourismrevenue, using the Verhulst model is evidently better than the others. For the number of international and domestic tourist prediction, the application of Verhulst and DGM(1,1) models is well done. For visitors coming from specific countries (i.e., China, Korea, Taiwan, Japan and America), DGM(2,1) is very poor for predicting in this situation, whereas remaining three models GM(1,1), Verhulst, DGM(1,1) and DGM(2,1) perform excellently. The results also pointed out that the tourism demands in Vietnam are growing rapidly; thus, the governments must be well prepared for tourismindustry and enhance relative fundamental construction for tourism markets.

- ABSTRACT: In the past few years, it is transparently observed a strict policy in Taiwan that government always has a tendency to focus on vocational and technical education, which is believed to create positive and miracle changes to their economy. However, to some extent, this trend faces several challenges: excellent courses and supporting facilities, long effective in raining workers, are becoming outdated; students are getting less interested in vocational schools; and funding priorities for educational restructuring are still ambiguous. In addition, this thesis uses then Grey System theory is applied for gathering and analyzing these data in the period of 2007 to 2013, which then can be forecasted to 2016, while Moving Average has its own limitations so it is just used to forecast for 2014. Based on the potentials and accuracy of Grey model e.g., Grey model is still able to be applied for short-time forecasting or missing data, this study has finally used this model for further analysis by using its forecasting results. Consequently, the researcher demand for statistical data in term of how these numbers will increase or decrease in near future. As a result, imultaneously, when the downturns go to the “hot” majors, the trend experiences a huge increase in the Home Economics. To be more specific, it is observed a gradual and slight decline with the Marine Products majors. Therefore, this study can clearly provide the Ministry of Taiwanese Education a comprehensive vision so that pragmatic actions  egarding education policies and resources allocation will be taken in the future.

- ABSTRACT:

Nowadays, foreign trade plays very important role in the economic development of any country. Especially, Vietnam also exports a lot of agricultural products to other countries and imports the capital goods from other countries. Therefore, it is not wrong to say that economic development of a country depends of foreign trade. Besides, foreign trade provides foreign exchange that can be used to remove the poverty and other productive purposes.The demand factor plays very important role in increasing the production of any country. The foreign trade expands the market and encourages the producers. In Vietnam,domestic market is very limited due to low income and others. So it is necessary to solve the problem we should sell our product in other countries.This is reason;the researcher had done thisstudy.There were 200managers of small and medium enterpriseswho interviewed and answered about 21 questions. The Data collected from April2016 to April 2017. This study had been analyzed Cronbach's Alpha, KMO testing and the result of KMO testing used for the next research of the regression.

- ABSTRACT: In Vietnam, highly competitive market in the private hospital industry has caused increasing pressure on them to provide services with higher quality. The aim of this study was to find out the factors affecting the business success of ITO private hospital through service quality (ITO Sai Gon - Dong Nai). Besides, the patient satisfaction is the most important parameter for judging the quality of healthcare service being provided by a service provider to the patient. Positive feedback from the patient leads to the goodwill of service providers in the market, which indirectly expands their business, whereas negative feedback makes it shrink. This theory is also applicable to healthcare providers. Nowadays, patients are aware of their rights in terms of healthcare services and the quality of healthcare services being delivered to them. The study results showed that there were 550 patients who interviewed and answered about 27 questions. Data collected from December 2016 to April 2017. This study had been analyzed Cronbach's Alpha testing and the result of Cronbach's Alpha used for the next research. Patients’ responses measured through an adapted questionnaire on a 5-point Likert scale (Conventions: 1: Completely disagree, 2: Disagree, 3: Normal; 4: Agree; 5: completely agree). Hard copy and online questionnaire distributed among 40.000 patients. Besides, the result of Cronbach's Alpha is very high reliability statistics. All of variables surveyed Corrected Item-Total Correlation greater than 0.3 and Cronbach's Alpha if Item deleted greater than 0.6 and Cronbach’s Alpha is very reliability with significance level 5 percent.

- ABSTRACT: Commercial Banks have always played an important position in the country’s economy. They play a decisive role in the development of the industry and trade. They are acting not only as the custodian of the wealth of the country but also as resources of the country, which are necessary for the economic development of a nation. Besides, risk management is the main cause of uncertainty in any commercial banks. Thus, commercial banks increasingly focus more on identifying risks and managing them before they even affect the business. The ability to manage risk will help commercial banks act more confidently on future business decisions. Their knowledge of the risks they are facing will give them various options on how to deal with potential problems. Risk management’s objective is to assure uncertainty does not deflect the endeavor from the business goals. The objectives of this study are to reliability analysis of the factors of the effectiveness of risk management of commercial banks in Dong Nai province. The data analysis for this study is a quantitative type.

- ABSTRACT: The recently developed local enriched consecutive-interpolation 4-node quadrilateral element (XCQ4) is extended to study transient dynamic stress intensity factors (DSIFs) for isotropic solids and anisotropic composite materials containing stationary cracks. The XCQ4 involves both nodal values and averaged nodal gradients as interpolation conditions to smooth the distribution of unknown variables. The possible physical properties of enriched nodes in consecutive-interpolation procedure (CIP) would be thought as non-locality feature, which could improve the accuracy of results and eliminate the non-smooth stresses among inter-elements. In XCQ4, the crack is determined by level set function and enriched by Heaviside and crack-tip enrichment functions with special anisotropic enriched crack-tip functions. Timedependent discrete equations for dynamic cracks are solved by Newmark time integration scheme at each time step without considering the effects of velocity-based global damping matrix. The proposed method is verified through a series of numerical examples of transient fracture in both isotropic and anisotropic materials. Numerical DSIFs are compared with reference solutions available in literature. The behavior of dynamic response is explored in specimens with complex configuration under step and sine loads.
