Academic setbacks such as incomplete (INC) grades and course failures remain persistent challenges to student retention in information technology programs in Philippine state universities. It is critical to distinguish between these two academic statuses: an INC grade signifies that a student has completed substantial coursework but has unfinished requirements due to valid, often extenuating, circumstances, whereas a failing grade denotes that the student did not meet the minimum academic standards for the course (Romero & Ventura, 2020). Adopting a proactive, preventive approach, this study analyzed contributing factors, support system utilization, and emotional impacts among 101 computing students at a state university in the Philippines using a validated structured survey. Quantitative techniques such as descriptive statistics, Spearman correlation, one-way ANOVA, chi-square, and multiple linear regression were applied. Financial difficulties (M=3.22), heavy course load (M=3.14), and time management issues (M=3.10) were the top-rated contributors. A regression model explained 37% of stress variance (R²=0.370; F(15,72)=2.82, p=.002), with lack of resources (β=0.433), work commitments (β=0.320), and subject difficulty (β=0.303) as significant predictors. Second-year students showed significantly higher resource and connectivity barriers across all ANOVA factors (p<.05, η²=0.07–0.12). Findings support the development of data-driven early warning systems and proactive academic advising frameworks within computing programs.

Solar water distillation systems are required for developing countries, especially in rural areas with an increasing population and environmental water pollution where there is no clean drinking water. Thus, solar still is the most important technology to increase pure water productivity in these regions. So, it is necessary to explore more about the system of solar distillation. In practical applications, design and performance analysis are essential to predict the efficiency of the solar still. This study aims to present the analysis of the temperature profile and fresh water output of the pyramid-shaped solar water distillation system by theoretical, numerical, and experimental analysis. The CFD simulation of the solar water distillation system was created using ANSYS FLUENT, and the experimental test was conducted in Mandalay, Myanmar, which is situated at a North Latitude of 21.996° and an East Longitude of 96.1° on 23rd April, 2022. In the performance analysis, the glass cover was tilted at 45°, and the water depth in the basin was 1 cm. For output verification, the experimental measurements were compared with theoretical and numerical results. The highest solar heat flux was 811.36 W/m2 in theory and 799.32W/m2 in experiment at 12:00 noon. During the solar still operation, the basin temperature was higher than the water and glass cover temperatures. The highest operating temperatures in the solar still in theoretical, numerical, and experimental analysis were 330 K, 331 K and 332 K respectively. The maximum pure water productivity was obtained at 335.5 ml/hr in theoretical analysis, 357.4 ml/hr in numerical analysis, and 437.5 ml/hr in experimental analysis. It has been found that all the analytical results among the theoretical, numerical, and experimental works show good agreement, which verifies and supports each other.
