This cross-sectional analytical study examined the relationship between academic pressure, family habits, personality traits, and school-related sedentary behavior among senior high school students in Iligan City. A total of 800 students aged 15 to 19 years from public and private schools participated. Data were collected using validated self-report questionnaires assessing academic pressure, family habits, personality traits, and sedentary behavior. Statistical analyses determined relationships and identified significant predictors. The findings showed that academic pressure, family habits, and personality traits had direct and significant relationships with school-related sedentary behavior. Identified predictors included sedentary mealtime behavior, sedentary entertainment viewing habits, despondency, sedentary reading and listening activities, and sedentary digital gaming and social media use. Emerging predictors included conscientiousness, worry about grades, open-mindedness, self-expectations, agreeableness, study-related pressure, and extraversion. Collectively, these models accounted for 14% to 23% of the variance in sedentary subscales. The results underscore the need to transition toward dynamic learning environments that integrate active breaks and digital wellness initiatives, alongside personality-sensitive support systems, to reduce sedentary habits and safeguard adolescent well-being.

The nano oxides were prepared in an environmentally friendly manner (by treatment with aqueous eucalyptus leaves (from trees in Diyala governorate, Iraq) extracts using different sources of iron, FeSO₄.7H₂O and FeCl₂.4H2O as the nanoscale iron oxide. The Fe (OH)₂ nanoparticles were obtained by slow addition of sodium hydroxide solution to eucalyptus extract. Then, to obtain α-Fe₂O₃, calcination of Fe (OH)₂nanoparticles was carried out at 550 °C. These oxides and nanocomposites were diagnosed by FTIR, XRD, FESEM, and DLS techniques. Brunauer-Emmett-Teller (BET) was used to determine the surface area of the nanomaterials. X-ray diffraction (XRD) examination showed that the size of α-Fe₂O₃ nanoparticles was 48 nm, characterized using several techniques, including XRD, AFM, FT-IR, and FESEM. These nanocomposites were used to study the adsorption of methyl orange dye from their aqueous solutions. The effects of equilibrium time, surface area weight, and temperature on the adsorption process were investigated. The results showed that the optimal equilibrium time was 40 min for the α-Fe2O3/paraffine nanocomposite and 60 min for the Fe2O3/AC nanocomposite. The optimal weight for dye removal was 0.25 g for the α -Fe2O3/paraffine nanocomposite. The optimal pH for removing methyl orange dye was 5 for all nano composites.
