Now in the 21st century the Dong Son and other historically renowned drum types have become symbols for Vietnam＇s emergence into an international cultural and economic arena. This paper charts three Vietnamese international events that illustrate the emblematic use of traditional drumming as a nationalistic symbol of modern Vietnam： The Third Asian Indoor Games held in Hanoi in 2009 opened with a drumming spectacle using battle drums; the Jubilee celebrations of the Vietnamese Catholic Church in 2010, opened in the north in the Ha Nam province with an immense traditional drumming performance within its religious setting; the 2012 Hue International Arts Festival incorporated ＂Resounding the Vietnamese Spirit＂, a specific drums and percussion festival, with performances using Binh Dinh war drums, royal drums from Hue, Dong Son drums, and Tay Son battle drums. These displays of traditional drumming it is argued have popularised particular nationalistic styles of drumming amongst Vietnamese youth, extending from the use of drumming in lion dance performances to the emergence of small, youth drumming groups who perform in the streets of Hanoi and Ho Chi Minh City展开更多

Using both total manufacturing industry and sub-manufacturing industrial regressions, the analysis focuses on the trend of technological progress (TP) and technical efficiency change (TEC), and the role of productivity change in economic growth. According to the estimated results, the annual technical progress for the manufacturing industry and sub-manufacturing industries are calculated directly from the estimated parameters of the translog stochastic frontier production function by taking a partial derivative of output with respect to time t. The average technical changes in manufacturing industry and sub-manufacturing industries are positive, with an average technical change about 5.2%, 5.8%, 5.4%, 11.8%, 4.6%, 4.1%, 7.3%, 4.8%, 4.8% and 4.8% for total sample, food products & beverages, textile & wearing apparel, footwear, paper & products, industrial chemicals, rubber & plastic products, non- metallic mineral, basic & fabricated metal and other sub-industries, respectively. Total TFP in the manufacturing sector has grown at the annual rate of 0.052, although the rate of growth decreased continuously during the sample period. For the sub-industry estimates during the sample period, TFP grew fastest in the footwear sub-industry, with annual average growth rate of 11.8%, followed by the rubber & plastic products with a rate of 7.3%, and the food products & beverages with a rate of 5.8% per annum.展开更多

Because of this, it is necessary to develop an exposure model that can realistically mimic clothes wearing conditions. This study aims to preliminarily develop a health risk assessment model for formaldehyde in clothing, and then to assess the potential health risk posed by formaldehyde in textiles to adults and infants in Vietnam using the model. Finally, this study aims to examine the plausibility of the adopted permissible values for formaldehyde in cloth- ing in Vietnam. In the model, two exposure factors for dermal exposure and overall exposure routes, i.e. sweat type and perspiration area, were considered. The margins of exposure (MOE) were calculated to estimate the health risks from worst case and average exposures. The assessment shows that acute exposure via inhalation can pose health risks to Vietnamese consumers in both cases. In regards to chronic exposure, dermal exposure is about four (for infants) and seven (for adults) times higher than exposure via inhalation, but no risks were found for average exposure. If a MOE of 100 is defined as ‘safe’ used, dermal and total chronic exposure to worst case cause potential risks, whereas no health risks were found for exposure to average case. With the model, the adopted Vietnamese permissible values for formaldehyde in clothing were assessed as not posing a health risk to Vietnamese consumers, hence they are accepted.展开更多

It plays an important role, especially in terms of food security for not only Vietnam but also the world. However, the Vietnamese Mekong Delta is projected to be heavily affected by： （1） the annual （fluvial） flood, which would be changed in terms of time and spatial distribution after impacts of climate change scenarios （i.e., sharper hydrograph with shorter flood period）; and （2） sea level rise. Such combination would result in significant changes of surface water resources, leading to consequent impacts on the existing fanning systems in the Vietnamese Mekong Delta. Therefore, this paper presents a new approach of integrating a one-dimensional hydrodynamic model （ISIS-1 D） with GIS （Geographic Information System ） analyses to： （1） identify priority areas for flood adaptation and mitigation; （2） provide an insight to local decision-makers in the Vietnamese Mekong Delta in changes of future floods.展开更多

Methods: The original English-language version was translated into Vietnamese, back translated and after some revisions tested for psychometric properties. Subjects (n = 724) were asked to self-administer a questionnaire but could ask for assistance. Convergent validity was tested by investigating associations between OHIP domain and total scores, and dichotomized self-reported satisfaction with 1) the dentition in general, 2) chewing function, and 3) esthetics. Groups validity was evaluated by comparing OHIP scores of subjects having ≤6 molars vs. >6 molars and tooth decay vs. no decay. Test-retest reliability was investigated in a convenience sample (n = 54) and expressed in Intraclass Correlation Coefficients (ICCs). Internal consistency was assessed by Cronbach’s alpha and average interitem correlation coefficients. Results: Validity: all associations were in the hypothesized directions. Differences in mean OHIP total were statistically sig-nificant for all discriminative variables. OHIP scores completed with assistance were significantly lower than those from self-administered questionnaires and therefore analyzed separately. For both administration formats differences in mean scores were still significant for “satisfaction” but for having ≤6 molars or decay the differences lost significance for most domain and total scores. Reliability: ICCs ranged from 0.54 - 0.74. Internal consistency: Cronbach’s alphas for OHIP total scores were 0.93 (self-administered) and 0.91 (with assistance). Average interitem correlation coefficients ranged from 0.26 - 0.67 (self-administered) and 0.28 - 0.69 (with assistance). Conclusions: This Vietnamese version of the OHIP-14 demonstrated good construct validity and acceptable reliability for OHIP total scores however OHIP-14VN domain scores should be interpreted with caution.展开更多

The most important contribution of Ly Thai To in Vietnamese history is to move the capital from Hoa Lu to Dai La, and rename it as Thang Long （Ascending Dragon） in 1010. Nowadays, it is known as Hanoi. Ly Thai To promoted Buddhism, and reduced the centuries-old influence of Confucianism in the kingdom. The growth and prevalence of Buddhism brought about a long period of peace, where Buddhist literature consequently flourished with seminal achievements. Due to King Ly Thai To＇s enormous contributions, the Vietnamese have created several legends and anecdotes to mystify his life. Thus, although a historical figure, his life remains a mystery and controversy. In 2010, Hanoi celebrated the 1000th anniversary of Thang Long. On this occasion, Vietnamese historical films about Ly Cong Uan were produced. This created intriguing variations within historical facts, legends, and on-screen stories. This paper will explore the reconstruction of Ly Cong Uan＇s life from an adaptation studies perspective through four historical films： Legend of the Capital Relocation （Huyen su thien do）, Thang Long Aspiration （Khat vong Thang Long）, Ly Cong Uan The Road to Thang Long Citadel （Ly Cong Uan： Dtrong toi thanh Thang Long）, Child of the Dragon （Ngtroi con cua Rong）. This research also wants to clarify the issues of national identity, nationalism, and cultural interaction reflected through the representations of Ly Thai To in those cinematic products展开更多

文摘The fascination of Vietnamese with drums and drumming reaches back into the pre-historic when bronze drums （Dong Son）, from the Red River Delta region of Vietnam＇s north, were prized trading commodities throughout the Asian world of that time. Now in the 21st century the Dong Son and other historically renowned drum types have become symbols for Vietnam＇s emergence into an international cultural and economic arena. This paper charts three Vietnamese international events that illustrate the emblematic use of traditional drumming as a nationalistic symbol of modern Vietnam： The Third Asian Indoor Games held in Hanoi in 2009 opened with a drumming spectacle using battle drums; the Jubilee celebrations of the Vietnamese Catholic Church in 2010, opened in the north in the Ha Nam province with an immense traditional drumming performance within its religious setting; the 2012 Hue International Arts Festival incorporated ＂Resounding the Vietnamese Spirit＂, a specific drums and percussion festival, with performances using Binh Dinh war drums, royal drums from Hue, Dong Son drums, and Tay Son battle drums.

文摘Deep learning created a sharp rise in the development of autonomous image recognition systems,especially in the case of the medical field.Among lung problems,tuberculosis,caused by a bacterium called Mycobacterium tuberculosis,is a dangerous disease because of its infection and damage.When an infected person coughs or sneezes,tiny droplets can bring pathogens to others through inhaling.Tuberculosis mainly damages the lungs,but it also affects any part of the body.Moreover,during the period of the COVID-19(coronavirus disease 2019)pandemic,the access to tuberculosis diagnosis and treatment has become more difficult,so early and simple detection of tuberculosis has been more and more important.In our study,we focused on tuberculosis diagnosis by using the chestX-ray image,the essential input for the radiologist’s profession,and researched the effectiveness of the transfer learning approach in the case study of Vietnamese chest X-ray images.We proposed four strategies to clarify our hypothesis in different ways of applying transfer learning and different training set types.We also prepared a Vietnamese X-ray image dataset with the support of the VRPACS team to provide the basis for training and testing deep learning models.Our experiments were carried out by applying three different architectures,Alexnet,Resnet,and Densenet,on international,Vietnamese,and combined X-ray image datasets.After training,all models were verified on a pure Vietnamese X-rays set.The results show that transfer learning is suitable in the case study of Vietnamese chest X-ray images with high evaluating metrics in terms of AUC(Area under the Receiver Operating Characteristic Curve),sensitivity,specificity,and accuracy.In the best strategy,most of the scores were more than 0.93,and all AUCs were more than 0.98.
文摘This study applies a stochastic frontier production approach to decompose the sources of total productivity (TFP) growth into technical progress and changes in technical efficiency of 8057 firms in Vietnamese manufacturing industries during 2003-2007. Using both total manufacturing industry and sub-manufacturing industrial regressions, the analysis focuses on the trend of technological progress (TP) and technical efficiency change (TEC), and the role of productivity change in economic growth. According to the estimated results, the annual technical progress for the manufacturing industry and sub-manufacturing industries are calculated directly from the estimated parameters of the translog stochastic frontier production function by taking a partial derivative of output with respect to time t. The average technical changes in manufacturing industry and sub-manufacturing industries are positive, with an average technical change about 5.2%, 5.8%, 5.4%, 11.8%, 4.6%, 4.1%, 7.3%, 4.8%, 4.8% and 4.8% for total sample, food products & beverages, textile & wearing apparel, footwear, paper & products, industrial chemicals, rubber & plastic products, non- metallic mineral, basic & fabricated metal and other sub-industries, respectively. Total TFP in the manufacturing sector has grown at the annual rate of 0.052, although the rate of growth decreased continuously during the sample period. For the sub-industry estimates during the sample period, TFP grew fastest in the footwear sub-industry, with annual average growth rate of 11.8%, followed by the rubber & plastic products with a rate of 7.3%, and the food products & beverages with a rate of 5.8% per annum.

文摘The assessment of potential health risks posed by formaldehyde in clothing to consumers is of increasing concern worldwide. Because of this, it is necessary to develop an exposure model that can realistically mimic clothes wearing conditions. This study aims to preliminarily develop a health risk assessment model for formaldehyde in clothing, and then to assess the potential health risk posed by formaldehyde in textiles to adults and infants in Vietnam using the model. Finally, this study aims to examine the plausibility of the adopted permissible values for formaldehyde in cloth- ing in Vietnam. In the model, two exposure factors for dermal exposure and overall exposure routes, i.e. sweat type and perspiration area, were considered. The margins of exposure (MOE) were calculated to estimate the health risks from worst case and average exposures. The assessment shows that acute exposure via inhalation can pose health risks to Vietnamese consumers in both cases. In regards to chronic exposure, dermal exposure is about four (for infants) and seven (for adults) times higher than exposure via inhalation, but no risks were found for average exposure. If a MOE of 100 is defined as ‘safe’ used, dermal and total chronic exposure to worst case cause potential risks, whereas no health risks were found for exposure to average case. With the model, the adopted Vietnamese permissible values for formaldehyde in clothing were assessed as not posing a health risk to Vietnamese consumers, hence they are accepted.

文摘In recent years,speech synthesis systems have allowed for the produc-tion of very high-quality voices.Therefore,research in this domain is now turning to the problem of integrating emotions into speech.However,the method of con-structing a speech synthesizer for each emotion has some limitations.First,this method often requires an emotional-speech data set with many sentences.Such data sets are very time-intensive and labor-intensive to complete.Second,training each of these models requires computers with large computational capabilities and a lot of effort and time for model tuning.In addition,each model for each emotion failed to take advantage of data sets of other emotions.In this paper,we propose a new method to synthesize emotional speech in which the latent expressions of emotions are learned from a small data set of professional actors through a Flow-tron model.In addition,we provide a new method to build a speech corpus that is scalable and whose quality is easy to control.Next,to produce a high-quality speech synthesis model,we used this data set to train the Tacotron 2 model.We used it as a pre-trained model to train the Flowtron model.We applied this method to synthesize Vietnamese speech with sadness and happiness.Mean opi-nion score(MOS)assessment results show that MOS is 3.61 for sadness and 3.95 for happiness.In conclusion,the proposed method proves to be more effec-tive for a high degree of automation and fast emotional sentence generation,using a small emotional-speech data set.
文摘The Vietnamese Mekong Delta is located at the end of the Mekong River, one of the 10 largest rivers in the world. It plays an important role, especially in terms of food security for not only Vietnam but also the world. However, the Vietnamese Mekong Delta is projected to be heavily affected by： （1） the annual （fluvial） flood, which would be changed in terms of time and spatial distribution after impacts of climate change scenarios （i.e., sharper hydrograph with shorter flood period）; and （2） sea level rise. Such combination would result in significant changes of surface water resources, leading to consequent impacts on the existing fanning systems in the Vietnamese Mekong Delta. Therefore, this paper presents a new approach of integrating a one-dimensional hydrodynamic model （ISIS-1 D） with GIS （Geographic Information System ） analyses to： （1） identify priority areas for flood adaptation and mitigation; （2） provide an insight to local decision-makers in the Vietnamese Mekong Delta in changes of future floods.
文摘Coordinate compounds are compounds in which the constituent components are grammatically equivalent.This study focuses on the contrastive analysis of the combination order of the words”constituent components making up coordinate compounds in both the Korean and Vietnamese languages to find the differences as well as similarities under the lens of cognitive linguistics.Specifically,this study looks into the combination order of the compounds”constituent components through the system of the senses—cognition through sensory perception,psychological mechanism—psychological cognition and social cognition of the Korean and Vietnamese people.
文摘Aim: To validate a Vietnamese short version (OHIP- 14VN) for use in epidemiological studies. Methods: The original English-language version was translated into Vietnamese, back translated and after some revisions tested for psychometric properties. Subjects (n = 724) were asked to self-administer a questionnaire but could ask for assistance. Convergent validity was tested by investigating associations between OHIP domain and total scores, and dichotomized self-reported satisfaction with 1) the dentition in general, 2) chewing function, and 3) esthetics. Groups validity was evaluated by comparing OHIP scores of subjects having ≤6 molars vs. >6 molars and tooth decay vs. no decay. Test-retest reliability was investigated in a convenience sample (n = 54) and expressed in Intraclass Correlation Coefficients (ICCs). Internal consistency was assessed by Cronbach’s alpha and average interitem correlation coefficients. Results: Validity: all associations were in the hypothesized directions. Differences in mean OHIP total were statistically sig-nificant for all discriminative variables. OHIP scores completed with assistance were significantly lower than those from self-administered questionnaires and therefore analyzed separately. For both administration formats differences in mean scores were still significant for “satisfaction” but for having ≤6 molars or decay the differences lost significance for most domain and total scores. Reliability: ICCs ranged from 0.54 - 0.74. Internal consistency: Cronbach’s alphas for OHIP total scores were 0.93 (self-administered) and 0.91 (with assistance). Average interitem correlation coefficients ranged from 0.26 - 0.67 (self-administered) and 0.28 - 0.69 (with assistance). Conclusions: This Vietnamese version of the OHIP-14 demonstrated good construct validity and acceptable reliability for OHIP total scores however OHIP-14VN domain scores should be interpreted with caution.
文摘Born as Ly Cong Uan, Ly Thai To is the first king of the Ly Dynasty. The most important contribution of Ly Thai To in Vietnamese history is to move the capital from Hoa Lu to Dai La, and rename it as Thang Long （Ascending Dragon） in 1010. Nowadays, it is known as Hanoi. Ly Thai To promoted Buddhism, and reduced the centuries-old influence of Confucianism in the kingdom. The growth and prevalence of Buddhism brought about a long period of peace, where Buddhist literature consequently flourished with seminal achievements. Due to King Ly Thai To＇s enormous contributions, the Vietnamese have created several legends and anecdotes to mystify his life. Thus, although a historical figure, his life remains a mystery and controversy. In 2010, Hanoi celebrated the 1000th anniversary of Thang Long. On this occasion, Vietnamese historical films about Ly Cong Uan were produced. This created intriguing variations within historical facts, legends, and on-screen stories. This paper will explore the reconstruction of Ly Cong Uan＇s life from an adaptation studies perspective through four historical films： Legend of the Capital Relocation （Huyen su thien do）, Thang Long Aspiration （Khat vong Thang Long）, Ly Cong Uan The Road to Thang Long Citadel （Ly Cong Uan： Dtrong toi thanh Thang Long）, Child of the Dragon （Ngtroi con cua Rong）. This research also wants to clarify the issues of national identity, nationalism, and cultural interaction reflected through the representations of Ly Thai To in those cinematic products
