Vam Ho bird sanctuary Natural Reserve (NR), Ben Tre province have many potential and opportunities to develop ecotourism due to its rich biodiversity, many wild birds with large populations. These wild birds are concentrated in this habitat, nesting, and breeding. However, the exploitation of ecotourism here is not commensurate with the existing potential, mainly spontaneous. Based on the literature related to Vam Ho bird sanctuary published, experiences and field surveys of the authors, potential assessment articles, analysis of the factors affecting the development of ecotourism, proposed Ecotourism development strategy in Vam Ho bird sanctuary NR in Ben Tre Province until 2022.

This study aimed at assessing the community participation in ecotourism at Bidoup Nui Ba National Park in Lac Duong District, Lam Dong Province. A qualitative exploratory study was conducted by questionnaire surey direct interview each household. The findings showed that: Community participated as responses to call to action and got paid for their participation. They gave ideas for development planning, but the National Park Management Board reserved the right to make decisions. (2) Four variables related to community’ participation included age, culture exchange, literacy, and residence period. (3) Local residents held positive attitudes towards tourism development because of benefits is created by tourism. It was the participants who had more positive attitudes and understandings than non-participants. This is the basis for proposing some solutions towards sustainable tourism development at Bidoup Nui Ba National Park.

Climate change has caused bad weathers, significantly impacted agricultural production. From agricultural restructuring to adapt to climate change, inefficient rice farm areas was changed into fruit farms. To improve the efficiency of production of mango “ba mau” (three colors), this study used Stochastic approach with Cobb-Douglass model to estimate the efficiency of the applied technology and determine factors that affected its production. The result indicated that 100% mango producers reached the efficiency in a range of 95 - 100%. Based on technical inefficiency function (TIE), this study determined three factors that affected technical efficiency of three colors mango, including applied science and technology (Z = - 0.050), technical qualification (Z = -0.023), years for harvest (Z = - 0.011).

In the salmon fillet processing industry, the amount of by-product is relatively high and is not used effectively. Salmon head and belly flap account for about 18% of by-products which have relatively high oil content (20%) and high nutritional value. Therefore, utilization of by-products for the processing of high quality of fish oil product is desirable. This study aimed to determine the most suitable processing conditions to enhance the yield and quality of the resultant salmon oil. This study investigated the effect of microwave power levels (495, 630 and 900 W) on the oil yield and quality. The results showed that salmon oil yield tended to increase and at the microwave powder of 900 W gave the high oil yield with good quality. Different moisture contents (15%, 20% and 25%) of the salmon head and belly flap prior to press was also investigated. The preliminary results indicated that the high oil yield was obtained when the moisture content was about 25%. The preliminary results also indicated that the rotation speed of the screw had a significant effect on the oil yield. The graphical optimization was adopted and it predicted the optimal press conditions including rotation speed of 9 rpm and moisture content of 22,5%. Under such conditions, the highest oil yield (84,2%) and good quality parameters including peroxide value (0,35 meqO2/kg), saponification value (188.1 mgKOH/g), acid value (3,5 mgKOH/g) and moisture content (0.89%) were predicted and confirmed.

This study aimed to investigate high school and university students' perceptions of filial piety and behaviors associated with the framework of filial responsibility in Vietnamese culture. The survey was conducted in the form of questionnaires to 300 students, including 150 students at a university in Tan Phu District, 75 students at an international private high school and 75 students of a public high school in District 3. The findings showed that most high school and university students' perceptions of filial piety were compatible with Vietnamese culture. In addition, those whose perceptions were considered 'right' according to Vietnamese culture generally tend to comply with their parents’ instructions more than the rest.

Corpus stylistics is a recent field of study in the contemporary Western stylistics, applying modern computational techniques to process large articles. Corpus-based approach has many applicable values in conducting research in Vietnam and has prospects of creating a breakthrough in research methodology and techniques. It will bring to Vietnamese language learning, which is based mainly on human intuition and manual analysis, a new trend of corpus quantitative analysis with the aid of computers. In order to help Vietnamese readers have basic knowledge of corpus- based approach so that they will have an in-depth thorough understanding of this field or apply it to research on the actual corpora, especially the corpora in Vietnamese language. This article introduces the basic research achievements of Western corpus-based approach. It has five main sections, including definition, approaches, research methodology, software tools, typical research works, strengths and limitations of corpus-based approach.

Vocabulary teaching with long lists of L1 equivalents in classes of grammar-translation method (GTM) at most high school contexts in Vietnam is criticized for abusing translation, focusing much on form and structure, lacking space for communicative performance; whereas communicative lan- guage teaching (CLT) is preferred in modern language teaching trends because it motivates learners’ discovery, participation and communication. How likely is it for EFL high school students to gain a significant improvement in their vocabulary acquisition through translation integrated with CLT in a communication-based translation activity (CTA)? This study suggests some CTA models for teaching and learning EFL vocabulary at high school in Vietnam based on the theories of receptive and pro- ductive vocabulary knowledge, and word processes by Nation (2001), together with the advantages of translation and characteristics of CLT. The study may provide practical implications for improving EFL students’ vocabulary and communicative performance at high school in Vietnam.

This study was conducted to examine the role of management commitment and management support in the quality of information system (IS) in enterprises in Ho Chi Minh City. This study included 175 participants working in different positions in businesses of various types. Data was collected primarily through the questionnaire (March, 2017 – June, 2017) and then it was analyzed for descriptive statistics, research reliability and validity and hypothesis testing through a multiple linear regression with the support of SPSS. Research results showed that the quality of IS was influenced by the training and the management support. In addition, some research implications were also presented to enhance the role of management as a factor in the quality of IS in Vietnamese enterprises.

The survey was carried out with participation of 30 farmers, 13 cooperative organizations, 270 samples (Soil, H2O and vegetables). Heavy metal contents and pesticide residues were collected to evaluate the food safety of vegetable production (SVP) and proposed solutions to improve the quality of SV products in the SVP chain in Can Duoc district and Can Giuoc district. The results showed that farmers had good conditions for safe vegetable production. However, 63% of the farmers were not licensed Food Safety Certificates. 30% of the farmers did not have irrigation systems. 24% of the households Lived in remote places and had difficulty with SVP transport. For cooperative organizations, 77% of the organizations had good conditions for processing SVP. 69% of the cooperative organizations had no internal quality control regulations; 46% of the cooperative organizations did not have one-way arrangement, 23% of the cooperative organizations did not fully participate in training and certification of food safety. There were found heavy metals (As, Cd , Pb, Cu, Zn ) in the soil and water in insignificant amounts. As a result of analysis of residues of pesticides in vegetables, there were 3.33% of SVP samples infected with Chlopyrifos (56,42 mg / kg); 2.22% samples infected with Cypermethrin (29.28 mg/kg) and 01 samples infected with Carbofuran with an average value of 1.06 mg/kg.

There are five types of couplets of “bien van”: “tu tu”, “bat tu”, “song quan”, “cach cu” and “goi hac”. In the Tang Dynasty, the ryhthm in the first clause must be 4 and that in the following must be 6. This is called antithetical couplets or“bien le” in Vietnamese; In Song Dynasty, “bien le” was regulated with “niem” and it came into academic writing. The name of “bien le” in this dynasty was “tu luc”. The difference between “bien le”, “tu luc” and the couplets mentioned above (called “old type”) is that “bien le” and ‘tu luc” are early modern type of couplets. One kind of a special “tu luc” was found in Nam Bo, is tu luc accompanied with “niem”. Some related works are “Sai vai” (Nguyen Cu Trinh), “Ki bao de tho” (A letter for younger brother) (Nguyen Dinh Chieu), “Hich Truong Dinh” (anonymous author's name),…

This article will explore two representative character types of anecdotes: intellectual character and crotchet character. From this study, we find in the anecdotes, the type of intellectual character, is based on two fundamental trends: perfectionism and earthiness. In crotchet character, the anec- dote builds the image through two main trends: showing talents, demonstrating characteristics and expressing opinions; and being against the royal power. The social and historical context which has formed the intellectual character is the examination system of the feudalism. However, the crotchet character has been grounded on the image of philosopher Trang Tu and the moral failure of the feu- dalism in the final stage of Le Dynasty and the beginning of Nguyen Dynasty.
