The research was done to assess the impact of groundwater resources degradation on agriculture in the coastal area of Vinh Chau District, Soc Trang Province. The structured and semi-structured interviewing method (households and local government) was used to determine the impact of declining groundwater resources on to agricultural cultivation (vegetable and aquaculture growing) of local farmers. The obtained results showed that the groundwater resources have had signs of degradation, causing impacts on exploitation and use of groundwater especially in agriculture and aquaculture. In particular, groundwater resources degradation have caused difficulties in extracting to irrigation leading to the increase of time and cost in irrigating, upgrading of pumping equipment. Moreover, groundwater resources degradation has also led to the increase in the number of well (drilling deeper wells in order to ensure enough water for irrigation because of the shortage of water of the former wells). The result of the study is the basis for supporting decision, planning, management and mining licensing for coastal provinces in the Mekong Delta.

Nitrogen biofertilizer was made from Burkholderia vietnamiensis CT1 in Burk's liquid without nitrogen (Park et al., 2005). It was stored for more than 3 months, then mixed with germinated seeds of high-yield rice (cv. OM4218). The efficacy of Burkholderia vietnamiensis CT1 was investigated on the OM4218 rice growth under pots condition, in the summer-autumn crop of 2016. The results showed that nitrogen biofertilizer of the Burkholderia vietnamiensis CT1 could replace up to 50% of N used for high-yield rice grown in pots, which had a significant effect on biomass accumulation, number of effective shoots of rice bush and the yild of rice harvested per pot compared to the control. The effect of nitrogen biofertilizer also affected significantly the accumulation of protein in the rice kernel and maintained the total N in the soil after rice harvest. In conclusion, Burkholderia vietnamiensis CT1 can provide up to 50% of the biological nitrogen needed for the growth and development of the OM4218 high-yield rice planted in pots.

The study of potential groundwater recharge in the Mekong Delta region is still limited. The study is to estimate the natural recharge of the groundwater and its response to the rainfall change in Hau Giang province. Based on observed precipitation and water level fluctuations in the past of ten years at eight monitored stations, groundwater recharge has been estimated, and the recharge map for the unconfined aquifer has been established for Hau Giang province. Then, by the obtained correlation equations rainfall and groundwater recharge, recovery potential maps of the groundwater resources for the future in years of 2020 and 2050 have been created using Kriging method under forecast rainfall data from the global climate model which based on Fourth Assessment Report (AR4). The results presented an application approach of data analysis and a tool for estimation and mapping of groundwater recharge. Results of study show the different level and imbalance between the amount of groundwater recharge (supply) and the exploitation (withdraw), which support the subtainable management plan of groundwater resources in Hau Giang province.

Coastal region has extremely harsh conditions for living. Plants changed the morphological and anatomical features for adapting to this particular environment. The plants, which live in coastal region of Nhon Ly, Quy Nhon city, Binh Dinh province, have adaptive traits with strong winds, high lighting intensity and drought conditions. The study was carried out on the morphological and anatomical features of 5 plant species of undershrub and grass in Magnoliopsida. The methods used include morphological comparison, microsurgery, double staining, microscope measurement and microscope photograph of leaf, stem and root. The results showed that the leaf palisade tissue developed (92.70% of leaf thickness), leaf upper epidermis is covered by thick hair layer or thick cuticle (4.55% of leaf thickness) which helped plant adapt to bright sunlight and high temperature; the short stem or growing close to the ground, the secondary xylem developed in stem (up to 59.21% of the stem radius) and in root (up to 78.34% of the root radius); xylem and phloem fibers much located in stem for adapting to strong winds; the high numbers of root xylem (183.17 ± 6.15 vessels/mm2 ) for adapting to drought.

It has been an emergency that wild medicinal plants resource has overexploited in An Giang province, and that led to the decrease of the source in recent years. This study sought to examine wild medicial plants diversity and distribution at Cam Mountain, An Giang in order to find an alternative medical plant source and record data for management and bioconservation. The study was conducted from August 2016 to May 2017 using the field survey methods to examine five featured areas with five pathways in Nui Cam. There were 120 species collected which belong to 54 families of Polypodiophyta and Magnoliophyta. Specifically, Magnoliophyta accounted for the highest number of species with 117 species belonged to 51 families, and the rest were found in the first phylum. The surveyed species could be classified into four groups regarding their growth habits in which the highest group was herbaceous plant (44 species), followed by the climbing and shrubs plants with 29 and 26 species, respectively. Woody plant was recorded as the lowest group with 21 species. Medicinal plants in this survey have been recorded as effective treatments for rheumatoid arthritis, body aches, cough, fever, and diarrhea. Roots were used popularly in herbal combinations among 11 plant parts categories. In terms of endangered species, there were six species recorded in Vietnam Red Data Book (2007).  The digital mapping was also conducted to site wild medicinal plants in this study area. Most plants were densely located along the trails (74 species) and inside the forest (69 species). The richest density of plant distribution was recorded between 400 m and 500 m mountain height.

1,3,4-Oxadizole exhibites a wide range of biological activities including antibacterial, antifungal, antiinflammatory, analgesic, hypolipidemic, anticancer, anticonvulsant, anti-diabetic, antiviral and ulcerogenic activities. In this study, two derivatives of 2-phenyl-5-(3,4,5-trimethoxyphenyl)-1,3,4-oxadiazole (6a) and 2-(4-methoxy-6-methylnaphthalen-2-yl)-5-phenyl-1,3,4-oxadiazole (8b) have been successfully synthesized in very good yields. The synthesis key step was cyclization of acylhydrazones into 1,3,4-oxadiazoles using stoichiometric amount of molecular iodine in potassium carbonate. The synthetic method also worked well with crude acylhydrazone substrates obtained from the condensation of aldehydes and hydrazides. Antimicrobial activity evaluation of two derivatives (6a) and (8b) showed that these two compounds possessed activity against three bacterial strains of Escherichia coli, Staphylococcus aureus and Bacillus cereus.

The study was conducted to identify the most common cestodes species which mostly affect dogs in some provinces of the Mekong Delta (An Giang, Dong Thap, Soc Trang, Kien Giang). There were 882 dogs examined for tapeworm infection by Skrjabin comprehensive method. The tapeworm samples were described based on the morphological and molecular features. The morphological features of tapeworm were identified for their properties such as scolex, neck, mature proglottid, gravid proglottid and egg. The genome sequences of tapeworm strains were obtained from the database resources of the National Center for Biotechnology Information (USA). The results showed that the infection rate of parasitic tapeworms in dogs was at 26,3%. The five species were Dipylidium caninum, Spirometra mansoni, Taenia pisiformis, Taenia hydatigena, and Diphylobothrium latum. Amongst them, Dipylidium caninum was the most common tapeworm species determined in this study with highest infection rate. The DNA sequencing indicated 96% of homologous gene sets of the American tapeworm Dipylidium caninum on the National Center for Biotechnology Information with the registration code AF023120.1

To develop the bio-safety duck farming is one of the most important directions of reorganization of our agriculture. Recent years, in the trend of integration the developing rate of biosafety duck production is increasing from day to day to meet consumption demands for the region and the whole the country. The government promotes farmers to incorporate bio-safety measures into duck production. This new duck farming system replaces the tradional one and has improved and get advantages for the producers. The results showed that the efficiency brought from bio-safety duck is higher than the tradional; this method of duck production brings farmers a lot of benefits, including extra profit, case study in My Duc district, Ha Noi city.

Households should add new techniques, invest in capital to develop efficient and sustainable biosafety model. Besides, the farmers have to been need the offering technical and financial support from the government and relevant agencies.

The study was conducted from October 2016 to August 2017. The method for E. coli isolation was done following Barrow and Feltham (2003) and Viet Nam standard, TCVN 5155-90. The results showed that 2,238 diseased ducks/44,750 surveyed ducks from 52 duck flocks, accounting for 5%. The isolated results from 200 fecal samples were E. coli positive at rate of 100%, specifically in lung (80.5%), in bone marrow (75.5%), in liver (74%) and lowest in spleen (71%). The disease caused by E. coli on ducks depended on breed as supper meat ducks (61%) was higher than Co duck (39%). The rate of disease of these ducks form 0 to 30 days old (51%) was higher than that of the ducks at 90 days old (26.5%) and 31 to 90 days old (22.5%). The serotypes of E. coli icluding O1 (12.73%), O78 (10.91%), O111 (8.18%), O35 (8.57%), O18 (7.27%), O92 (5.71%), O36, O81 and O93 accounted for 2.86%, the serotype of O2 that did not find. The E. coli was moderate resistant to ampicillin (54.44%), streptomycin (53,85%), trimethoprim/sulfamethazine (53.85%) and tetracycline (52.07%) and showed multi-drugs resistance from 2 to 12 out of 13 kinds of antibiotics with 79 diversified and complex resistant patterns. The sensitive antibiotics can be used for treatment of diseases on the ducks caused by E. coli were cefuroxime (97.63), doxycycline (91.72%), florphenicol (91.12%), amikacin (90.53%), ciprofloxacin (82.25%), ceftazidime (75.74%), colistin (75.15%), ofloxacin (65.68%), and gentamycin (65.09%).

To identify molecular markers linked to salt-tolerant gene of rice, both phenotypic and genotypic evaluation of salt tolerance were performed atseedling stage. The phenotypic screening forsalinity stress at EC=12 mS/cm was doneusing the standard protocol of the International Rice Research Institute. About 23.7% of rice varieties were identified as salt tolerant, 28.9% were moderately tolerant, 39.5% were susceptible and 7.9% were highly susceptible. Two SSR markers (RM493 and RM3412) have shown the ability (over 70%) for salt tolerant identification in all groups. Additionally, 36 rice varieties were grouped into 7 major clusters by UPGMA method based on these markers. Most of tolerant genotypes belonged to cluster I while moderately tolerant genotypes were in cluster II and III. From clusters IV to VII included susceptible and highly susceptible genotypes. These results indicated that RM493 and RM3412 were useful for marker assisted selection at seedling stage.

Dry root rot has been damaging over a wide range of Citrus nobilis, causing a decline in fruit yield and quality. The objective of this study was to evaluate some selected physical, chemical and biological soil properties in order to provide the basic data for reducing dry root rot disease.

A factorial experiment design with eight treatments, and three replicates for each, was carried out to evaluate the combined effect of C/N ratios (5, 10, 15 and non C/N manipulated cultures) and feeding regimes (standard feeding regime (SF) and 2/3 SF) on performance and biomass production of Artemia franciscana under laboratory conditions. The result showed that the growth in length of Artemia was reduced as a result of reduced feeding regime; however, Artemia length was increased when molasses was added. However, the survival of Artemia was not improved by molasses addition into Artemia culture. The Artemia biomass production was reduced by reducing feeding regime, but the biomass production increased when molasses was added into the culture, especially Artemia biomass production was significantly increased (p < 0.05) in the treatment with SF and C/N 15 and 2/3 SF and C/N 5 as compared to that obtained in the respective control treatment. The results indicated that Artemia length and biomass production were improved when molasses was added to obtain C/N ratios at 5 and 15, especially biomass production at reduced feeding regime (2/3 SF) was nearly equal to that obtained in SF when C/N 5 was applied.

Zoning of aquaculture water quality in Cau Hai lagoon was conducted by comparing with the national standards (QCVN02-19:2014/BNNPTNT, QCVN08-MT:2015/BTNMT, and QCVN38:2011/BTNMT) through the help of GIS. Temperature, dissolved oxygen (DO), nitrate parameters were suitable to aquaculture activities. One hundred percent of the area had pH values in suitable range for aquaculture in the dry season, whereas only 79.4% was in the rainy season. Salinities were most in suitable range for shrimp culture. The alkalinity was unsuitable for aquaculture in rainy season and dry season was respectively 88.04% and 28.92%. BOD5 levels exceeded the QCVN08-MT:2015/BTNMT standard. Phosphate contents were not suitable for aquaculture with 91.13% and 53.57% of the areas the rainy season and dry season, respectively. Un-ionized ammonia concentrations exceeded the standard, with 41.68% and 36.55% of the areas in rainy season and dry season, respectively. The concentrations of total coliform were higher than the standard with 63.33% of the areas in rainy season and 44.19% in the dry season.

The study on the fishing activities of inshore trawlers and inshore gill nets was conducted from March to December 2017 in Bac Lieu province. The results showed that the inshore trawlers and inshore gill nets had highest number of fishing boats and yields. Trawlers and gill nets can capture whole year round, and the main fishing season was from November to coming April. The scale of gill net boats was (41.3±14.2 CV), larger than that (36.1±15.1 CV) of trawl boats. The yield and ratio of trash fish of gill nets were (13.5±3.9 tons/year; 16.8%) lower than those (18.7±2.4 tons/year; 41.2%) of trawlers, but profits and benefit ratios of gill nets (429±311 million VND, 1.05±1.03 times, respectively) were higher than those of trawlers (162±162 million VND, 0.68±0.64 times, respectively). Therefore, in the future, government should promote developing gill nets and restrict development of trawlers. For the sustainable development of trawl nets and gill nets, the development and management of fisheries resources should be promoted, supporting fishermen to access low interest rates to invest in production, and training fishermen to use fishing equipment to increase their fishing efficiency.

The study was conducted to assess the effects of different supplementation level of Grobiotic®-Ain the diet for growth and disease resistance of catfish (Pangasianodon hypothalamus). Four experimental diets were formulated to contain different GroBiotic®-A levels namely 0% (control), 1%, 2% and 4%. Five replicate groups of fish (80 fish per 500 L tank with an average body weight of 15.14±2.79 g) were assigned to each diet for 60 days. Results showed that growth rate of fish fed diets containing GroBiotic®-A were significantly higher (p0.05) in growth performance among diets containing between 1% and 4% GroBiotic®-A. Feed conversion ratio in the 4% GroBiotic®-A treatment was lowest and statistically different from the control and the 1% and 2% GroBiotic®-A groups. Moreover, after 21 days of challenge test, the 4% GroBiotic®-A diet gave the best resistance against hemorrhagic disease caused by bacteria Aeromonas hydrophyla that could be considered a suitable level for catfish diet.

The smallscale croaker Boesemania microlepis (Bleeker 1858) exploitation status on the Bassac river, Mekong Delta was conducted from January to October 2017 through direct interviews with 90 fishing households by using the prepared questionnaire. The results show that the smallscale croaker is exploited all year round on the Bassac river. The fishing season is concentrated from February to April and from July to November (lunar calendar) annually. The smallscale croaker production on the Bassac river is decrease by more than 45% compared to that 5 years ago. The highest average production is in the upstream of the Bassac river, followed by the downstream and the lowest one is in the middle. Smallscale croaker is mainly consumed as unprocessed fish for local traders. The main difficulties of the smallscale croaker exploitation are the decline in production, the fluctuation in price of products, fishermen’s lack of information about the market. Most of the trawl nets fishing households lack the capital to invest in fishing. The erratic change of the weather greatly affected smallscale croaker exploiting production on the Bassac river, Mekong Delta.

Dramatically increasing trend of urbanization and industrialization promotes visitors to look for simple beauty, fresh air and traditional cultural values ​​in the countryside. Therefore, rural tourism has become a development trend in many countries all over the world. Tinh Bien district, An Giang province has great potential for developing rural tourism based on Khmer community. However, most of the tourism resources in this area have existed in the form of potential, and tourism activities are spontaneous, ineffective, and without generating income for the people. This paper is to analyze the tourism potentials and propose solutions for rural tourism development based on Khmer community which contribute to improving people's living conditions and boosting construction of new rural areas.

Forecasting export prices is very important for exporters and policymakers to make strategic business decisions. The objective of the study was to apply the seasonal autoregressive integrated moving average (SARIMA) model to predict the short-term export price of tiger shrimp using the monthly time series data of free on board (FOB) price at size 30-40 pieces/kg in the period from January 2011 to December 2016. The results confirmed that the SARIMA (2,1,1)(0,1,11)12 model was the most suitable for explaining the fluctuation of black tiger shrimp prices. The forecasting model was proved to be very reliable; the predicted shrimp prices in January 2017 were roughly equal to the real ones with the 95% confidence interval.

The result form Cobb – Douglas regression reveals agricultural growth in Can Tho by increasing physical capital for agriculture, expanding land due to irrigation and technology. Of the total inputs, physical capital had the most important contribution to the output growth (40,51%), Total factor productivity contributed 33,28% to the agricultural output growth.

This paper is aimed at proposing an effective model for measuring impacts of information technology (IT) on components of competitive capacity (CCC) of enterprises in Can Tho city. The research is based direct interviews of enterprises in Can Tho city selected through stratified random sampling by their fields of activity. The respondents include enterprise’s directorate board, chief accountant and department heads, those are knowledgeable on (enterprise’s activities) and responsible for enterprise’s performance. The results from qualitative and quantitative analyses showed that the application of IT in business activities are very important and meaningful for enterprises. Without IT application and e-commerce then the enterprise would be very difficult to compete with others. In addition, the application of IT and e-commerce could cut many operation costs which in turn helps the enterprise develop faster, enhance its competitiveness and effectiveness in the course (context) of economic integration.

This study is aimed to investigate the awareness of Can Tho University undergraduates in Mutual Recognition Agreements fields towards labour mobility within ASEAN Economic Community (AEC), and, as a result, to propose some suggestions to raise students’ awareness of this issue. This study uses descriptive statistics, Stages of Concern Questionnaires from Concerns-Based Adoption Model, crosstabs and Chi-square method to analyze the samples of 680 observations. Some important findings are: firstly, 85% respondents have heard about AEC, yet only half of them have known about free movement of professionals within AEC; secondly, in general, students are aware of, though not significantly, and expect to receive more information about this matter; thirdly, those with better individual ability or more positive attitude towards international labour mobility are more likely to have a higher level of concern. Therefore, several proposals which focus on enhancing communication activities as well as students’s specialization and soft skills were made.

Health practitioners who give diagnosis and treat treatment – called doctors in the scope of this research – are highly clarified among the noble proefessions. However, similar to other professions, if they negligently cause omissions, they must be responsible for the damage. Medical malpractice is defined as any act or omission by a physician during treatment of a patient that deviates from accepted norms of practice in the medical community and causes an injury to the patient (translated from the definition of Medical malpractice, abbrreviated MM). MM is a problem occurring all over the world in different levels. In this study, on the basis of the general provisions of the MM generally applied in the Member States of the European Union, the study is to focus on analyzing and comparing the two legal systems of Belgium and England. Whereby, the following contents will be studied on negligent omissions, the elements which establish doctor’s liability, the common negligent omissions, and systems of compensation for damage. The research shows that although the Belgian and English legislations have similarities, there are differencies to adjust the malpractice of the doctors.
