This study compares the accuracy of four soil moisture sensors differing in unit costs in coarse-, fine- and medium-textured soils. The sensor outputs were recorded for the VWC, ranging from 0% to 50%. Low-cost capacitive and resistive sensors were evaluated with and without the external 16-bit analog-to-digital converter ADS1115 to improve their performances without adding much cost. Without ADS1115, using only Arduino’s built-in analog-to-digital converter, the low-cost sensors had a maximum RMSE of 4.79% (v/v) for resistive sensors and 3.78% for capacitive sensors in medium-textured soil. The addition of ADS1115 showed improved performance of the low-cost sensors, with a maximum RMSE of 2.64% for resistive sensors and 1.87% for capacitive sensors. The higher-end sensors had an RMSE of up to 1.8% for VH400 and up to 0.95% for the 5TM sensor. The RMSE differences between higher-end and low-cost sensors with the use of ADS1115 were not statistically significant. 2026-02-24T00:00:00Z http://umt-ir.umt.edu.my:8080/handle/123456789/23398 Title: CHILDREN'S SOCIOEMOTIONAL SKILLS Authors: PSNZ Abstract: Mindfulness is a skill that enables individuals to accept their thoughts and feelings without judgement and to focus on their immediate experiences. It is important to determine the effects of mindfulness activities on children during the preschool period, as this is critical for their development. In this study, the systematic review method was used to examine the effects of mindfulness practices conducted with preschool children on their development. It is expected that the study will contribute to the scientific literature in terms of understanding the effects of mindfulness on children's different developmental areas and behaviours; it is also expected that it will be serves as a guide on the development of educational programmes and intervention practices to support mindfulness skills at an early age. The research included scientific studies and theses on mindfulness in preschool children (36-72 months) in Google Scholar, YÖK Thesis Centre, Tandfonline, ProQuest, EBSCO, Wiley Online Library, MEDLINE, Sage Journals, DergiPark, and JSTOR databases, which were conducted between 2015-2025 and could be accessed in full text. The databases were searched using the keywords "mindfulness" and "preschool" in English and "okul öncesi,” "mindfulness,” and "bilinçli farkındalık" in Turkish, which were determined by considering the subject title and the relationship with the purpose of the study. As a result of the search, 51 sources, 11 theses, and 40 studies were included in the review. The research results show that mindfulness-based programs have the potential to positively affect children's executive functioning, self-regulation skills, and social-emotional development. This study highlights the importance of early interventions and offers evidence-based guidance for future educational programs. 2026-01-25T00:00:00Z
