Factors affecting sustainable ecotourism in Vietnam: Mediating role of tourist satisfaction and attractive destination

The paper aims to identify factors affecting sustainable ecotourism in Vietnam, including the mediating role of tourist satisfaction and attractive destinations. The valid quantitative data were collected from a survey of 515 domestic tourists who have traveled to ecotourism areas in 5 selected areas in Vietnam, including Ca Mau Province, Can Tho City, Ho Chi Minh City, Binh Dinh Province, and Dong Nai Province. To test research hypotheses, data were analyzed using AMOS 24.0 and structural equation modeling (SEM). Research results show that tourist satisfaction strongly affects sustainable ecotourism (β = 0.341), followed by attractive destinations (β = 0.175) and environmental awareness (β = 0.147). In contrast, tourism management policy does not affect sustainable ecotourism. Besides, tourism management policy has the strongest influence on attractive destinations (β = 0.393), followed by the natural environment (β = 0.129), culture and society (β = 0.082), but infrastructure does not affect attractive destinations. Research results also show that the strongest influential determinant of tourist satisfaction is infrastructure (β = 0.448), followed by culture and society (β = 0.180), the natural environment (β = 0.150), and tourism management policy (β = 0.136).

Assessment of the impact of ethnic minorities’ capacity in Binh Dinh province, Vietnam, to access land and exercise land use rights by application of linear structure model (PLS-SEM)

Abstract The study aimed to evaluate the impact of ethnic minority people’s capacity on land access and exercise of land use rights. The research model and hypotheses were tested using exploratory factor analysis (EFA) and PLS-SEM methods with 70 preliminary quantitative survey samples and 273 official quantitative survey samples of ethnic minorities. The research results revealed that strengthening the capacity of ethnic minorities is the key to improving their effectiveness in accessing land and exercising land use rights. The research findings demonstrate a robust and affirmative correlation between the capacity of ethnic minorities to acquire land access and the implementation of land use rights (βCO→LA = 0.325; βCO→LUR = 0.736; estimated path coefficients close to +1 represent strong positive relationships). The research model attains a significance level of 1% (tCO→LA = 8.412; tCO→LUR = 42.643). The outcomes of this research can serve as a foundation for the People’s Committee of Binh Dinh Province, Committee for Ethnic Minority, to further establish policies, support programs, and training to enhance the capacity of ethnic minorities, and to provide guidance on improving the effectiveness of land access and exercise of land use rights for this community.

Biodiversity of coral reefs and associated seagrass beds in Quy Nhon Bay, Binh Dinh Province

The distribution of critical marine habitats in Quy Nhon Bay, Binh Dinh Province, was assessed with the combination of resolution of Google Earth images and local knowledge through local consultations and ground truthing using small boats to check the sites supporting coral reefs and seagrass beds with local involvement. Detailed surveys on species diversity and conditions of marine habitats were conducted at 24 sites of coral reefs and four sites of seagrass beds at three sites (Nhon Ly, Nhon Hai, Ghenh Rang, and Nhon Chau) in 2016–2017. More than 152 ha of coral reefs, 5 ha of seagrass beds, and 720 species belonging to 7 key groups (290 species of fishes; reef-building corals: 194, molluscs: 123, seaweeds: 47, echinoderms: 40, crustaceans: 20 and seagrasses: 6 species) associated with the above habitats were recorded in the Bay. Among them, 92 species were facing different threats, in which 3 species were endangered (EN), including branching corals (Alveopora minuta), flat pen shells (Atrina vexillum), and top shells (Tectus pyramis); 38 species at vulnerable (VU); and 51 species at near threatened (NT) following the IUCN Red List and Vietnam Red Book. In general, the coral reefs and seagrass beds at Bai Dua and Seo Island (Nhon Ly); Kho Nho Island, Bo Dap (Nhon Hai); S. Ngang Island, Bai Nam and Bai Nom of Dat Island (Ghenh Rang); Da Ban, Bai Lang, Bai Lang Ba and Ong Gia Island (Nhon Chau) supported higher diversity and better conditions than other sites. Establishing restricted zones at these sites is an urgent need, but it also holds the premise of sustainable utilization and conservation of resources in the future.

Survival and Growth of Food Borne Harmful Fungi during Storage of Vietnamese Ramie Leaf Rice Cake

Background: Ramie leaf rice cake is a traditional dessert in Vietnam. To date, there are no data regarding the nature of mycotoxins that may contaminate this product in this country. This study was conducted to find out if harmful fungal strains were present in traditional ramie leaf rice cake in Binh Dinh province, Vietnam. Method: The ramie leaf rice cake samples were collected at traditional cake production facilities in Binh Dinh province, transported to the laboratoryand then kept at room temperature. After 3 to 5 days, the cake began to mold, with a slimy surface and a rancid smell. We then carried out microbial analyses. The genetic correlation between the fungal strains discovered was then determined. Results: The isolation process and preliminary identification through morphological characteristics revealed the presence of four harmful fungal strains. After PCR identification and ITS sequencing, the results showed that the four fungal strains belong to the genus Aspergillus: Aspergillus niger, Aspergillus flavus, Aspergillus tamariiand Aspergillus fumigatus. The traditional Binh Dinh ramie leaf rice cake in Vietnam is very perishable due to Aspergillus fungus if not consumed quickly. Producers and consumers should pay attention to storage methods, especially during transportation to other areas.

Characteristics of first-time blood donors with unsatisfactory hemoglobin level and positive hepatitis B test in Binh Dinh Province

Blood transfusion is essential in the treatment of a various diseases. In order to guarantee a safe and sufficient volume of blood supply, it is crucial to select appropriate donors based on stringent eligibility criteria. The objective of this study was to furnish robust epidemiological information and identify the risk factors linked to hepatitis B virus (HBV) infection and low hemoglobin levels in first-time blood donors in Binh Dinh. Understanding the causes for donor deferrals can assist better plan and establish an efficient recruiting strategies as well as evaluate donor selection criteria. A cross-sectional study was undertaken in Binh Dinh Provincial General Hospital from November 2022 to February 2023 to examine individuals in their first-time blood donation. Data were sourced directly from voluntary blood donation registration forms. HBsAg results were assessed using rapid immunochromatographic tests and chemiluminescent immunoassays. The rate of unsatisfactory hemoglobin levels was 2.56% tested on 1,638 participants. This rate was significantly associated with female sex (18 times greater odds than males), and lower weight. The results revealed that the rate of HBV infection was 3.13% when detected by the rapid test, but increased by 0.58% when measured by chemiluminescent microparticle immunoassay. The positive hepatitis B deferral correlated with sex (p<0.05), age group (p<0.05) and occupation (p<0.05). HBV was found the leading cause of deferral in the study area and associated with males, age groups (25–35 and 36–44), officer, worker-farmer, and self-employed people. The prevalence of low hemoglobin donor deferral obtained was 2.56%. Low hemoglobin deferral is associated with female gender, lower body weight, worker-farmer, and self-employed - others. This finding underscores a significant public health concerns, highlighting the need for strategies to lower the infection rates. Understanding the factors leading to defered donation can contribute to development of proactive strategies for recruiting and retaining donors.

Evaluation of surface water quality and carrying capacity as planned by 2030 in the Lai Giang River basin, Binh Dinh Province, Vietnam

The quality of surface water in the river basin under the influence of industrial development and urbanization is one of the issues that need attention in the management of water resources in Binh Dinh province. The study assessed water quality in the Lai Giang river basin gives an overview of the surface water quality situation and predicts future changes in wastewater reception through the 2030 planning scenario. The study corrected the NAM model flow at An Hoa hydrological station with R2 = 0.777 and BIAS = 5%. The results of adjustment of water level and flow in 2016 for R2 are 0.893 and 0.731, respectively. The test of water level and flow in 2017 for R2 is 0.882 and 0.582 respectively, along with the test result of water level in 2021 is 0.689. The calculation of the current carrying capacity in 2021 and the planning scenario in 2030 shows that there is still capability to receive, but consideration should be given to rational use of water resources.

Assessing the water potential and wastewater load capacity of the La Tinh River, Binh Dinh province by MIKE 11AD and Ecolab model combined with GIS method

The study used the NAM model of flow simulation with a time series of 14 years (2008 - 2021), statistical analysis method, and MIKE 11 AD water quality model, and Ecolab combined with GIS method to calculate wastewater reception capacity and load capacity of the basin. The model validation is highly reliable with a model efficiency factor of R2 of 0.777 and BIAS = 5%. The results of the application of the NAM model have determined the daily flow series of 14 years (2008 - 2021) and the average flow characteristics of many years of the La Tinh basin such as Qo flow is about 5.9; 6.0 m3/s, total amount of Wo = 292.1; 188.8 million m3 flow modulus Mo = 19.3 l/s-km2 flow class Yo = 611 mm and flow coefficient α= 0.3 for all sub-basins. The results of the study show that the capacity of receiving wastewater, the capacity of most river sections in the La Tinh basin is still received with five parameters at a relatively high level, the section of the Binh Tri river upstream alone has exceeded its capacity to receive. This is one of the very useful tools in integrated management and effective use management of river basin water resources.

The objective of this study is to evaluate the sensitivity, specificity, and accuracy of artificial intelligence (AI) for diabetic retinopathy (DR) screening in community in Binh Dinh Province in Vietnam. This retrospective, descriptive, cross-sectional study assessed the DR screening efficacy of EyeArt system v2.0 by analyzing 2332 nonmydriatic digital fundus pictures of 583 diabetic patients from hospitals and health centers in Binh Dinh province. First, we selected thirty patients with 120 digital fundus pictures to perform the Kappa index by two eye doctors who would be responsible for the DR clinical feature evaluation and DR severity scale classification. Second, all digital fundus pictures were coded and then sent to the two above-mentioned eye doctors for the evaluation and classifications according to the International Committee of Ophthalmology's guidelines. Finally, DR severity scales with EyeArt were compared with those by eye doctors as a reference standard for EyeArt's effectiveness. All the data were analyzed using the SPSS software version 20.0. Values (with confidence interval 95%) of sensitivity, specificity, positive predictive value, negative predictive value, and accuracy were calculated according to DR state, referable or not and vision-threatening DR state or not. P < 0.05 was considered statistically significant. The sensitivity and specificity of EyeArt for DR screening were 94.1% and 87.2%. The sensitivity and specificity for referable DR and vision-threatening DR were 96.6%, 90.1%, and 100.0%, 92.2%. Accuracy for DR screening, referable DR, and vision-threatening DR were 88.9%, 91.4%, and 93.0%, respectively. EyeArt AI was effective for DR screening in community.

The influence of destination images and emotional value on visitors' satisfaction and return intention in Quy Nhon City

This study assesses the influence of tourist destination images and their emotional value on the satisfaction and return intention of domestic tourists in Quy Nhon City, Vietnam. 500 tourists visiting Quy Nhon City were surveyed using a convenient sampling method. The authors use structural equation modeling (SEM) to show that destination images and emotional value have a direct impact on visitor satisfaction. Destination images also impact on their return intentions. Moreover, the study also indicates that the destination image can be measured via four key factors: natural features, tourism facilities, infrastructure, and government support. Some implications are given to tourism businesses and policymakers of Binh Dinh Province. This can be a valuable aid in identifying key issues for tourism development in the region and help in the development of service measures aimed at increasing tourists' return intentions.

Impact of the customary law on the implementation of land use rights of Bana ethnic minority in Vinh Thanh district, Binh Dinh province

The study was conducted to test the impact of customary law on the exercise of land use rights of ethnic minorities. The research model of the paper is the linear structural equation model (SEM). The method of partial least squares (PLS) tests the SEM model with 124 survey samples of households and individuals of the Bana ethnic group in Vinh Thanh District, a mountainous district in West Northern Binh Dinh Province, Vietnam. The research results show many differences between customary law and law in implementing land use rights of the Bana ethnic minorities, leading to transactions on land use rights of the Bana ethnic group not being registered at the state agency. The research results confirm a robust relationship between customary law and the exercise of land use rights of ethnic minorities. This relationship is shown through the significance level of the research model achieved at 1%; the coefficient β for evaluating the relationship between customary law and the exercise of land use rights is 0.458. The estimated path coefficient close to +1 indicates a strong positive relationship. The research results provide some suggestions for further integrating customary law into the law in implementing and developing land law policies to improve the efficient implementation of land use rights for ethnic minorities.

Bio-agronomic characteristics of new promising short duration rice (Oryza sativa L.) lines and varieties in Central Vietnam

Rice is an important food crop in Vietnam and facing challenges due to climate change, limited cultivation area, and limited adaptable varieties. Therefore, field experiments were carried out in two seasons of summer 2022 and spring 2023 at the Agricultural Science Institute for Southern Coastal Central of Vietnam (ASISOV), Binh Dinh province, to evaluate the growth, development and yield of new promising short duration rice lines and varieties in Binh Dinh province. Promising 10 lines and varieties namely ANS1 (control), BDR97, BDR57, BDR79, BDR87, BDR36, Line 159, Line 243, Line 64, and Line 46 were used for the study. They were arranged in a randomized block design with three replications. Research results showed that the duration of rice lines and varieties ranged from 90 to 112 days. The yield of the lines and varieties was from 5.94 to 7.44 t/ha in the summer season 2022 and 6.42 to 8.05 t/ha in the spring season 2023. The quality of rice lines and varieties was rated from average to good. Two new promising varieties were identified, including BDR79 and BDR57, with a short duration of 91-103 days, yield from 7.27-8.05 t/ha, higher than the control variety from 11.6-20.5% and belonging to good quality classification.

Toward sustainable community-based tourism development: Perspectives from local people in Nhon Ly coastal community, Binh Dinh province, Vietnam.

Community-based tourism (CBT) is no longer a new form in many countries, including Vietnam. However, the approach of CBT in a sustainable manner, especially in coastal villages, where tourism has recently emerged as an alternative livelihood, has received little attention. This study explores the impact of tourism on the lives of the local community, the level of people's participation in tourism, and the challenges of tourism development in the coastal commune of Nhon Ly, Binh Dinh province. By utilizing a qualitative method such as observation and semi-structured interviews with 19 villagers engaged in tourism, the results show that tourism contributes significantly to the lives of the residents in Nhon Ly (e.g., improving income, changing livelihoods from fishing to tourism, improving environmental awareness). However, tourism development has obstacles related to local people's skills and knowledge working in tourism and their limited participation in tourism policy and planning. Other issues were related to the negative impacts of tourism on cultural-social and environmental aspects in Nhon Ly. Therefore, there is a need for comprehensive coordination among all tourism stakeholders, building long-term strategies to overcome barriers toward sustainable CBT development in the future.

ASSESSMENT OF THE POTENTIAL FOR DEVELOPMENT OF AGRITOURISM IN BINH DINH PROVINCE, VIETNAM

This study evaluates the potential for agritourism development in Binh Dinh Province, Central Vietnam. The analytical hierarchical process is used to determine the weights of four factors with 25 measurement criteria to assess agritourism potential. The research results show that Binh Dinh Province has great agritourism potential based on four evaluation factors, including (1) local agricultural tourism resources, (2) the trend for agritourism development and the agritourism market, (3) the local community’s willingness, and (4) the supporting activities of the local government. In particular, the local agricultural tourism resources factor received the highest score, followed by the local community’s willingness and the supporting activities of the local government. The trend for agritourism development and the agritourism market was rated the lowest. Therefore, Binh Dinh has viable opportunities to encourage the growth of agritourism to improve farmers’ livelihoods

Impact of gender equality on implementation of land use rights through land access of ethnic minorities in central Vietnam

The study was conducted to test the impact of gender equality on implementing land use rights through land access of ethnic minorities. Preliminary scale evaluation using Cronbach's Alpha coefficient and EFA exploratory factor analysis with 100 survey samples was performed using SPSS 26.0 software. The official quantitative research model was tested by the partial minimum average method (PLS) in SmartPLS3 software with 349 survey samples from 3 ethnic minority groups, including Cham, Bana, and Hre, in Binh Dinh province, a province in the center of Vietnam. Research results show that all three ethnic groups, Cham, Bana, and Hre, who participated in the survey, said that women currently face many disadvantages in accessing land and exercising land use rights compared to men. The research results confirm a solid positive indirect and positive relationship between gender equality and the exercise of land use rights through the intermediate variable of land access. The research results contribute some theoretical implications in developing land policies to achieve equality in land access, improve land access and realize land use rights for ethnic minorities women.

Sequence stratigraphy and evolution of the southern Central Vietnam Shelf during Late Pleistocene-Holocene

The central Vietnam continental shelf is located on the western margin of the East Vietnam Sea (South China Sea). This study provides new findings regarding the Late Pleistocene-Holocene evolution of the southern central Vietnam shelf off Binh Dinh province using high-resolution seismic profiles and sediment cores. The study found that the Late Pleistocene-Holocene sequence stratigraphic model of the study area can be divided into three systems tracts: the regressive systems tract (RST), the transgressive systems tract (TST), and the highstand systems tract (HST). The RST is the oldest and thickest of the three systems tracts and is characterized by forced regressive and lowstand deposits. These deposits likely formed between the Marine Isotope Stages (MIS) 5e highstand and the Last Glacial Maximum (LGM) termination. The RST is well-preserved at water depths deeper than 60 m and has a maximum thickness of about 40 m. The TST is the middle systems tract and was likely deposited during a postglacial transgressive period, from the LGM lowstand termination to around 8 cal ky BP. The TST is thickest in shallow water depths in the southern part of the study area and within incised-valley systems. The HST is the youngest of the three systems tracts and is dominated by thick mud clinoforms that prograde onto the shelf following mid-Holocene sea-level highstand until the present day. The HST was primarily deposited in shallow water depths of 0–50 m and decreases in thickness towards the outer shelf, ending at a water depth of around 80 m.The study also found that Late Pleistocene-Holocene relative sea-level change is the main factor controlling the overall stratigraphic organization of units on the study area. The presence of the beach-ridge structure at a water depth of approximately 140 m below the modern sea level in the southernmost part of the study area suggests that the region experienced a sea-level lowstand in the past. This lowstand was likely a result of subsidence due to a high sedimentation rate. This discovery is consistent with earlier studies conducted on the central Vietnam shelf. There are similarities in the deposition of Late Pleistocene-Holocene deposits between Binh Dinh and other shelves worldwide, indicating that there may be consistent controlling factors that govern the geological history of these regions. However, the thickness and distribution of deposits in the study area may be different due to local factors that interacted to shape the area differently than others.
