title: IMPROVING THE QUALITY OF EDUCATION IN TECHNICAL SCHOOLS USING ARTIFICIAL INTELLIGENCE: ISSUES OF THE TEACHING PROCESS, EDUCATIONAL ACTIVITIES AND QUALITY ASSURANCE (IN THE CONTEXT OF UZBEKISTAN)

description: The rapid integration of artificial intelligence (AI) into technical colleges systems has created new opportunities for enhancing educational quality. This study examines the role of artificial intelligence in improving teaching and learning practices, assessment systems, student support mechanisms, and institutional quality assurance processes. Using a qualitative conceptual research design based on a systematic review of international literature and policy documents, the paper analyzes how AI-driven tools contribute to student-centered learning, data-informed decision-making, and continuous quality improvement. Particular attention is given to the context of technical colleges reforms in Uzbekistan, where digital transformation has been identified as a strategic priority. The findings indicate that artificial intelligence can significantly enhance learning outcomes, institutional efficiency, and transparency when aligned with quality assurance frameworks. However, challenges related to ethics, data protection, digital readiness, and staff capacity remain critical. The study concludes with strategic recommendations for the effective and responsible integration of AI into technical colleges quality systems.

title: SEA_Cropland10: Annual 10-m high-resolution cropland maps for Southeast Asia since 2019

description: SEA_Cropland10 is a high-resolution (10-meter) annual cropland dataset covering Southeast Asia from 2019 to 2024, achieving overall accuracies exceeding 92%. Developed within Google Earth Engine, it synergizes Sentinel-1 SAR and Sentinel-2 optical imagery with embeddings from the AlphaEarth foundation model. This integration effectively mitigates challenges posed by persistent cloud cover and complex terrain, significantly improving the detection of fragmented smallholder farms and sloping agriculture compared to existing global products.

The dataset is provided as binary raster layers: cropland pixels—encompassing paddy fields, drylands, and sloping agriculture—are assigned a value of 1. All non-cropland categories (e.g., forests, water, built-up areas) and regions outside the study area are masked as NoData, ensuring the data strictly represent cultivated land.

Specifications & Usage:





Format: GeoTIFF (WGS 84, EPSG:4326)




Resolution: 10 meters




Temporal Coverage: Six annual layers (2019–2024)



This dataset is optimized for regional food security monitoring, analyzing land-use change dynamics, and assessing agricultural expansion into highland areas. It is fully compatible with standard GIS software (QGIS, ArcGIS) and spatial analysis environments (Python, R).

title: Accelerometer Dataset from Office Workers Collected on Weekdays

description: The dataset was collected using Axivity AX6 accelerometers (Axivity Ltd., UK). Each participant (n = 69) wore a single device positioned on the upper back in the paravertebral region at the C7–T1 level to record continuous triaxial acceleration signals related to posture and physical activity.

The main dataset includes processed accelerometer data exported in .csv format.

To support behavioural validation, participants completed daily self-reported activity diaries. These diaries are provided in .xlsx format and are additionally available as a compressed .zip archive.

For sensor calibration and activity classification, a separate calibration group (n = 30) performed a standardised experimental movement protocol. Calibration files include raw device recordings (.cwa), processed data (.csv), and annotated protocol files (.xlsx) for each participant.

The data are available upon reasonable request, please communicate with the authors (jelena.reste@rsu.lv; nadina.rimere@rsu.lv)

title: A spectral induced polarization instrument using square-wave current injection to track critical zone processes: application to long-term monitoring of a wetland (Guidel, France).

description: Dataset of spectral induced polarization measurements collected in the wetland area at the Ploemeur-Guidel hydrogeological observatory, to monitor reactive processes with high spatial resolution across the top meter of soil. The spectral content of a signal with line spectrum resulting from square-wave current is exploited by injecting successively three square-wave currents with periods of 1, 10 and 100 s, covering the frequency range of 0.01 to 100 Hz in less than 4 minutes. One dataset consists of eight successive current injections at different depths. For each current injection, the electrical potential is simultaneously measured at seven dipoles. The time-series are recorded with a 2 kHz sampling rate, allowing the Fourier transform of the time-series into amplitude and phase spectra for each quadrupole. Details can be found in the corresponding paper.

title: КОМПЛЕКСНАЯ ДИАГНОСТИКА РАННЕГО РАКА ШЕЙКИ МАТКИ

description: Рак шейки матки остаётся одной из ведущих причин онкологической заболеваемости и смертности среди женщин репродуктивного возраста. Эффективность лечения и прогноз заболевания во многом определяются стадией, на которой установлен диагноз, что подчёркивает важность раннего выявления патологического процесса. В данной статье представлен аналитический обзор современных методов комплексной диагностики раннего рака шейки матки, основанный на анализе отечественных и зарубежных научных источников. Рассмотрены возможности и ограничения цитологических, молекулярно-биологических, кольпоскопических и морфологических методов исследования, а также их роль в выявлении предраковых изменений и начальных форм злокачественного процесса. Особое внимание уделено значению ВПЧ-тестирования как высокочувствительного метода скрининга и необходимости его сочетания с цитологическим и инструментальным обследованием для повышения специфичности диагностики. Показано, что комплексный подход обеспечивает более точную стратификацию риска, снижает вероятность гипо- и гипердиагностики и способствует своевременному выбору оптимальной тактики ведения пациенток.

title: Willingness-to-taste in UK children aged 4-7 years was driven by contextual facilitation, not intervention, in a randomized controlled trial of sensory food education

description: Data comprise the anonymised quantified results of the OASES RCT study. Data reflect individual participant behaviour during a vegetable and fruit tasting activity, conducted before (baseline) and after (follow-up) a six session sensory food education intervention ('Flavour School') delivered by school teachers during class time. Children were free to taste (or not) any/all of nine samples (7 vegetables, 2 fruit). Participants were individually video recorded during the activity. Primary outcomes were willingess-to-taste the foods offered, mean valence of facial expressions (positive/negative/neutral), termed 'Enjoyment', and a count of changes of facial expression, termed 'Expressiveness'.
