Colegio de San Juan de Letran grade 7 students socioeconomic characteristics and engagement in violent video games and academic grades
No full textThis paper focuses on the socioeconomic characteristics and engagement in violent video games and academic grades of the Grade 7 students of Colegio de San Juan de Letran-Calamba. It covers their sex, family income, and number of hours spent playing video games. The study was conducted using survey questionnaires administered to a total of 97 participants, 50 of them are male and 47 of them are female. Moreover, there are different income classes present in the participants and majority of them, belongs to the upper-middle class. In the findings, 53 out of 97 participants has an academic average ranging from 90-94. In terms of playing video games, most of them are interested in multiplayer online games which totaled to 68 students. There are 85 students who engage in violent video games and there are 11 who do not. From the results, the median score for sex and academic grade is 90–94. The correlation coefficient (rho) of family income and academic grade is -0.09, a very weak negative monotonic relationship. This also holds true for the number of hours spent playing video games and academic grades, which have a very weak negative monotonic relationship with a rho of -0.05. Lastly, the association between engagement in violent video games and the academic grades of the students resulted in a negative relationship with a point biserial coefficient of -0.07
Correlates of mental health and coping mechanisms among BS Human Ecology students at the University of the Philippines Los Baños
No full textThe study examined the mental health and coping mechanisms of undergraduate students during the transition to various learning modes at the University of the Philippines Los Baños. Results showed that female students experienced significantly higher levels of distress than males, whereas no significant differences were found in psychological well-being. Coping mechanisms did not differ significantly between the sexes, except for positive reframing. Year-level differences in coping mechanisms were observed for active coping and self-blame. No significant differences in mental health and coping mechanisms were seen across learning delivery modes. Correlation analysis found that only sophomore and senior students show significant relationships between financial status and psychological distress or well-being. Sophomores with high financial status showed increased distress and well-being, while seniors displayed a weak positive correlation between financial status and distress. Moreover, results revealed that freshmen had negative correlations between financial status and planning as well as acceptance. Sophomores exhibited a positive correlation between financial status and humor as a coping mechanism. Junior students displayed moderate positive correlations between income groups and coping mechanisms such as humor, self-blame, and substance use. Senior students with higher financial status demonstrated associations with self-distraction, venting, positive reframing, denial, and avoidant coping. Considering the weak to moderate relationships found, future studies should explore additional variables for a holistic understanding of the correlates of mental health and coping mechanisms among BS Human Ecology students
Gray to green: will households pay for constructed wetlands as nature-based water treatment in Peri-urban areas in the Philippines?
No full textConstructed wetlands (CWs) are globally recognized as effective nature-based wastewater solutions. These systems use natural processes to clean wastewater, which has significant environmental and socio-economic benefits. As a result of increasing urbanization and a growing population, the Philippines is suffering from extreme water pollution. Effective wastewater management is essential in human settlements planning as it protects public health and the environment by reducing water source contamination and disease transmission. It also enhances overall sustainability and livability, leading to a higher standard of living. Economic analysis is required to determine the long-term viability ofsustainable projectssuch as CWs. This study employed the contingent valuation approach to investigate the willingness to pay (WTP) of 270 households in Fishermen’s Gawad Kalinga Village in Bayawan, Negros Oriental. Results showed that 96.3% of the respondents were willing to pay for constructed wetland services, with a mean WTP of 107.28 PHP. This holds a significant promise for the government and other stakeholders to embrace and invest on NBS to wastewater treatment such as CW projects. Future research should focus on cost-benefit analysis and real-options analysis to strengthen the study by comparing costs and benefits and investigate the flexibility and adaptability of the project

No full textAcademic performance satisfaction of the Senior High School Students during the High School remote learning setup
No full textThe transition from the face-to-face to remote learning setup brought about various challenges to both the students and instructors which has affected their learning and teaching. Determining the students’ academic performance satisfaction will help in developing a better online learning system and educational environment. The main objective of the study is to analyze the academic performance satisfaction and related of factors of senior high school students. Questionnaires, containing both closed- and open-ended questions, were given out to the senior high school students online and face-to-face. Responses were analyzed using Spearman’s ρ and thematic analysis. This study found that overall the students are satisfied with their academic performance during the remote learning setup and have positive perceptions of these factors that affect it: learner-content interaction, learner-instructor interaction, and learner-learner interaction. From gauging potential challenges, it was identified that students have proper mean to learn remotely and put in their best efforts. However, it was also found that there is a split on whether students have adapted to the remote setup, have a favorable remote setup, or have a satisfying learning experience in the remote setup. Lastly, the majority of students were found to have experienced technical difficulties and have issues with mental health and motivation. The correlational analysis found strong positive relationships between the level of satisfaction and learner-content interaction (ρ=0.6911, p\u3c0.001); and between the level of satisfaction and challenges (ρ=0.6359, p\u3c0.001). Moderately positive relationships were found between learner-content interaction and learner-instructor interaction (ρ=0.5228, p\u3c0.001); and between learner-content interaction and challenges ( ρ=0.5724, p\u3c0.001). The thematic analysis found the following themes around students’ mental and environmental situations: student engagement, student personal factors, student’s environmental factors, student grades, the learning setup, and the student’s accessibility issues

A study on the voting preferences of first-time voters in the 2022 presidential elections
No full textYoung individuals who are first-time voters make up a large portion of our voting population. With the recent national elections that took place, it is important to look at what affected their voting preferences, especially those who voted for the first time. This study aims to evaluate the factors that affected voting preferences of first-time voters in the 2022 presidential elections together with how different sources of information influenced first-time voters’ voting decisions. Using an online survey, preliminary data were gathered along with possible participants for the interview. The online survey showed that most of the first-time voters who responded voted for the top 2 presidential candidates, Ferdinand Marcos Jr. and Leni Robredo, hence the participants for the interview were voters of the top 2 candidates only. There were a total of 6 interviews conducted for this research, and with the data gathered from these interviews common themes were identified through thematic analysis in relation to the voters’ voting preferences, environmental influences, and political participation. The study found that some of the qualities of a candidate that first-time voters looked into were their educational background, experience in government service, and cultural background as these can all be attributed to competency and ability to lead the country. Social media also played a huge part for first-time voters for information and as a platform for online political participation which contributed to their political knowledge and decision making. Lastly, the study also found their voting decisions are influenced by their families and friends as they engage in political discourse with them. Ultimately, these results contribute to political awareness of young individuals by putting importance on the reasons behind a vote, but could also be used as a springboard for further studies on voter’s education to create more critical voters in our country
Angiotensin Iconverting enzyme inhibitory and antioxidative activities of the bioactive peptides in the crude salt-soluble protein hydrolysates of pili nut (Canarium ovatum Engl.) cv. mayon kernel
No full textThe in silico enzyme digestion and peptide function annotation of pili nut (Canarium ovatum Engl.) 11S globulin protein sequence revealed the presence of bioactive peptides with antihypertensive and antioxidative activities. Molecular docking simulations showed that the proline-histidine (PH) ligand can better inhibit angiotensin I-converting enzyme (ACE) activity than captopril. This result was verified through biochemical assays. Pili kernel protein was extracted with 0.5 M NaCl buffer using the modified Osborne fractionation method, which yielded 100 mg of protein per gram of defatted pili kernel determined via Bradford assay. SDS-PAGE suggested that the protein extract had a major legumin-like (11S) globulin structure with an approximately 57 kDa molecular weight. Enzymatic hydrolysis using pepsin, thermolysin, α-chymotrypsin, and trypsin was used to release the potential antihypertensive and antioxidative peptides with an average rate of 0.03869 mm2 h-1, estimated from band intensity. The hydrolysates were tested for ACE inhibition and free radical scavenging. Captopril and enalapril had %ACE inhibitions of 74.02 and 83.57 %, respectively, whereas the 6 h hydrolysates had a peak %ACE inhibition of 99.73%. These same hydrolysates however, only had 51.32% 2,2-diphenyl-1-picrylhydrazyl (DPPH) radical scavenging activity compared to ascorbic acid, which had 75.59%. These results showed the potential of pili nut as a functional food, especially for preventing high blood pressure and other cardiovascular diseases
Dry matter production of two rice cultivars with contrasting root plasticity expression under different topographic conditions subjected to soil moisture fluctuation
No full textIn rainfed lowland rice fields characterized by sloping terrains and the presence of a hardpan in a flat topography, plants are often exposed to soil moisture fluctuation (SMF) stress due to erratic rainfall patterns. Root plasticity is one of the key traits that play important roles in plant adaptation under such conditions. In this study, two contrasting genotypes, KDML105 and IRAT109, were examined to quantify the expression of plasticity in root branching at different positions in the toposequence (TP) and in a flat topography with a hardpan, both without a groundwater table, and subjected to SMF. Results showed that KDML105 exhibited improved adaptation to SMF conditions due to its greater root system because of the promoted nodal root production and development of lateral roots in the upper soil layer (0 – 20 cm soil depth) along the TP and above the hardpan in a flat topography, which led to the maintenance of its stomatal conductance and dry matter production. IRAT109, on the other hand, did not express root plasticity in deep-rooting due to the absence of groundwater table, particularly in the upper TP, as well as branching ability above the hardpan in a flat topography, which resulted in less water uptake and reduced dry matter production under SMF. Overall, the results indicated that root plasticity in the upper soil layer could be an important trait for the adaptation of rice, both in a sloping TP without a hardpan or in a flat topography with a hardpan, experiencing SMF
