Preoperative prediction of International Federation of Gynecology and Obstetrics (FIGO) stage in patients with epithelial ovarian cancer (EOC) is crucial for determining appropriate treatment strategy. This study aimed to explore the value of contrast-enhanced CT (CECT) radiomics in predicting preoperative FIGO staging of EOC, and to validate the stability of the model through an independent external dataset.

Forest fires present a significant threat to the tropical forest ecosystem in the northwestern region of Vietnam. Our study aimed to assess the impacts of environmental factors on forest fire occurrence and to map forest fire probability for the whole region. The forest fire occurrence data over the period 2003–2016, environmental factors (climate, fuel condition, topography, and human activity), and the MaxEnt approach were used for this study.

High school teachers are mentors and facilitators that must be concerned about their students' formal thinking abilities. Students may not take a conservation task seriously because they perform operations without consulting. This necessitates modifying the learning process to increase student motivation.

The purpose of the study is to develop evaluation methodology and evaluate agro-industrial territorial-economic systems that have a significant production potential of agricultural sectors in the regions of the Russian Federation. The author justifies the choice of indicators and evaluation criteria. The study was based on economic and mathematical modeling of empirical spatial data, calculated on the basis of official statistical information within the Russian Federation regions.

In the first post-war decade, studies of the problems of the regional economy were developed in many countries based on the supply chain management. Prerequisites were created for the unification of regional scientists and a new attempt to synthesize theories of spatial and regional economics. At this stage, the avant-garde role was played by an American scientist, W. Isard.

The paper "Applying machine learning algorithms to classify forest cover type from sentinel 2 MSI data" presents the results of forest cover classification in Dak Lak province from Sentinel 2 optical satellite image data using machine learning techniques. Sentinel 2 MSI images taken in November 2015 and December 2020 are used to classify forest cover objects and then evaluate forest cover changes in the period 2015-2020.

In the research "DEM generation and topographic changes of central Hanoi, Vietnam" a DEM is generated using elevation data from a newly published topographic map in 2018. By comparing the two patterns of DEM for 2005 and 2018, the areas of urban transformation can be clarified. These high-resolution DEMs are useful not only for analyzing the urban transformation of central Hanoi but also for urban sustainable development, as in the improvement of urban infrastructure and disaster prevention.

In the study "Distribution, fate and ecological toxicity of some heavy metals in sediment: A case study from Day river downstream, Vietnam" the 50 surface sediment samples were collected along Day River downstream in July 2018 and January 2019 (25 sampling sites) to clarify the status, movement and potential risk of some heavy metals (Cr, Pb, Cu, Cd and Hg). The receptor model of Principal Component Analysis (PCA) was applied to track the source types of these metals.

The study "Three-dimensional building model using drone point clouds" primarily outlines the theory of high-resolution aerial mapping for 3D construction using drone point clouds of the Provincial Hall in Chiang Rai Province, in northern Thailand. The use of geographic information systems (GIS) to support and convey information to environmental managers and the general public is excellent for presenting data obtained from ongoing location monitoring.

In the study "Building a 3D information model for underground coal mines" a 3D information model for a mine is built using BIM. The Industry Foundation Classes (IFC) standard is used to define the mining information model. Point clouds collected by Terrestrial laser scanning (TLS) provide geometric and attributive information for building BIM models. This information model was applied to the NUI BEO underground coal mine. The information model was built for important structures of the mine, including the mine shaft and tunnels.

In the study "Swash model approach for flows induced by low-frequency waves over wooden fences" the low-frequency wave, which is considered the main contribution to flows, is focused on assessing the possibility of sediment transports through the wooden fence. This study applies the SWASH model developed by Delft University of Technology to carry out a couple of wave scenarios for the southeast and northeast monsoons that were inherited from a previous study.

The paper "The role of orographic effects on heavy rainfall event over central Vietnam in October 2021" use observation data and high-resolution (3 km) simulations from the WRF model, driven by FNL data, to investigate the causes of heavy rain over Central Vietnam from 22nd to 29th October 2021. Our findings confirm the significant role of topography in causing heavy rain. In terms of the atmosphere’s vertical structure, the surface’s northeast wind, almost perpendicular to the Central region’s topography, combined with the east wind and trade winds above, caused strong convection.

The paper "A novel approach of neural networks and USLE in smart soil erosion modeling, case study in Southern coastal of Viet Nam" adopted one of the neural networks - the Long ShortTerm Memory (LSTM) to analyze temporal variations in erosion patterns over time, aiding in understanding erosion dynamics. Furthermore, another common soil erosion model - the Universal Soil Loss Equation (USLE) was investigated to predict annual soil loss. Our data were extracted from remotely sensed data (DEM - Digital Elevation Model and MODIS) and vector data of the study area.
