ASSESSING THE SUSTAINABILITY OF URBAN LAND USE IN PLEIKU CITY, GIA LAI PROVINCE

Nguyen Ninh Hai, Nguyen Thi Lan Thuong, Nguyen Thi Ly, Nguyen Thi Ha, Truong Quoc Minh
Sustainability in land use plays an important role in the urbanization process toward achieving the goals of the 2030 Agenda for Sustainable Development. This study integrates Earth observation data through satellite imagery analysis combined with field surveys to assess the Urban Land Use Efficiency (ULUE) by using the land use efficiency index, estimates the relationship between land use, population growth, and the urbanization process in Thang Loi ward over a 20-year period. The findings reveal inefficient urban land use, where the expansion rate of built-up areas exceeds the population growth rate in the studied area. From 2002 to 2022, the population and built-up area increased by 339% and 460%, respectively. In most of the expanding areas, there is widespread hoarding and fragmentation of land use, with numerous plots of land being vacant or underutilized for many years due to lack of control. Therefore, to improve land productivity and ensure sustainable urban growth, the local government should consider improving the Urban Land Use Efficiency Index.
Primates play a huge role in biomedical research. They are raised for medical research and to test new vaccines before being used for humans. The yellow-cheeked gibbon (Nomascus gabriellae) is an endemic mammal of Vietnam, included in the Vietnam Red Book 2007, and described in the IUCN Red Book 2009. This species is an endangered species found only in a small region of Indochina, and its populations have declined in most known sites. The purpose of this article is to present an overview research on taxonomy, identification, reproduction, behavior, ecology, distribution, population, and conservation status of this species. The overall results are intended to support the conservation of this rare endemic animal species and provide reference in related biomedical research.
This study which entitles “Learners’ Attitudes towards the Project Works in promoting English learner autonomy: a Case Study at Foreign Trade University-Ho Chi Minh Campus” was conducted with the following objectives: (1) to investigate students’ attitudes towards the use of project works to enhance their autonomous learning in an English speaking class; (2) to find out to what extent students believe that using project works can promote their autonomous learning; and (3) to figure out difficulties that learners have during the time they conduct Video making project. The study population was 73 second-year students who took the course English listening and speaking 2. An open-ended questionnaire and semi-structured interview were employed as research instruments for data collection. The result firstly shows that the students have positive attitudes towards the use of project works in English class that may have enhanced their autonomous learning. Then, it reveals students’ preference in having more project works to do in their English classes. Nonetheless, using project works’ evaluation as one of criteria for course assessment is a controversial issue among these students. In addition, students’ interest in utilizing information technology devices is remarked as one of the significant findings in this study. Furthermore, some difficulties when conducting projects are found including time constraints, teamwork conflicts, cultural differences and technology problems. In short, because of students’ positive attitudes toward Video making project in enhancing their autonomous learning, it is suggested that teachers should consider applying the project in their language teaching.
Vietnam's economy is operated to serve more than ninety million people so this is a very vivid picture. The large population brings many advantages to the food production sector in general and the production of fresh noodles in particular. Fresh vermicelli is the raw material for processing many dishes of the Vietnamese people for a long time, that's why there are many Vietnamese dishes with indispensable ingredients, which as Noodles in the national culinary books. Vietnam. The production of fresh vermicelli with the main ingredient is fermented and shaped rice with simple steps, but hidden inside there are environmental issues that need to be considered. The production and business associated with environmental protection are the responsibility of most enterprises and production facilities in Vietnam. The fresh noodle food production industry is no exception. Instead of learning about the aspects that affect the environment in the traditional way of collecting information, analyzing, and evaluating the current situation, this time the research team looked at understanding the causes of environmental pollution in terms of consumption. ISO 14001 international standard. ISO 14001 Environmental Management System is an international standard that helps businesses and establishments identify the important role of the environment as well as the risks brought by the environment, thereby realizing the environment as an activity of the Organization. In this standard, the commitment to prevent environmental pollution is a mandatory condition, so determining the environmental aspects to overcome the impacts is a key element of the standard. If a business achieves ISO 14001 Certification, it will have a very good effect in promoting the corporate image of being responsible for the environment and the community.

Through analysis of the DPSIR model, combined with research methods such as field surveys, and survey questionnaires, the author has given the following results: The amount of waste is increasing; Not paying attention to the classification at source, Solid waste collection is still limited; Environmental quality is degraded due to the stench caused by domestic waste in some neighborhoods; The soil environment is polluted due to solid waste treatment that is difficult to decompose; Surface water and groundwater are also leaked due to leachate, wastewater from landfills; The polluted environment has, directly and indirectly, affected the health and production and business activities of the people in the ward, degraded the ecosystem, and lost the urban beauty. The author has proposed solutions to reduce environmental pollution caused by domestic waste such as population policy, establishing collection groups, craft village planning, and applying the circular green model in economic development.
Binh Duong is a province in the Southeast region. It has a long history of growth and numerous noteworthy historical and cultural values. This paper provides a summary of the cultural and historical significance of Binh Duong Province during the prehistoric, land exploration, and settlement phases. It discusses population, administrative structure, social structure, economic traits (agriculture, handicrafts, commerce), and social culture throughout the various eras (prehistory, settlement phase, Nguyen dynasty). The findings demonstrate that Binh Duong not only has a rich history with numerous economic and cultural assets, but also point to possible research avenues for safeguarding and advancing moral principles in the construction and development of Binh Duong province today and in the future.
Declining supplies of fossil fuels, increasing population, global industrialization and demand for transportation fuels has triggered an increase in the demand for renewable energy sources. To address such problems most of the green research in the recent years has focused on the development of bioethanol (23 MJ/L) as a substitute to conventional gasoline (34.3 MJ/L) based fuels owing to the similarity in energy density values in addition to several other advantages (American Council on renewable energy, 2010). Second-generation biofuels are derived from lignocellulosic biomass or woody crops, mostly coming from agricultural residues. Extraction of fuel from such biomass is difficult because of their recalcitrant nature (corn stover, rice straw, wheat straw, sugar cane and sweet sorghum). Lignocellulosic fuel has the potential to solve several problems (food competing with fuel) that are currently associated with first generation biofuels. Moreover, lignocellulosic fuels can supply a larger proportion of the global fuel leading to sustainability at lower cost, and with greater environmental benefits (Liz Marsall, 2009). The production of ethanol from the complex sugars in leaves and stalks is a promising strategy to radically broaden the range of possible ethanol feedstock. Keywords: lignocellulose, bioethanol, biomass, pretreatment, hydrolysis, fermentation.
