ABSTRACT:
This study examines the determinants of online academic dishonesty using the theory of planned behavior. We surveyed 1087 college students in Central Philippines and utilized a partial least squares-structural equation modeling analysis to evaluate a proposed model. Results demonstrate that 10 of the 11 hypothesized relationships are statistically significant. Moreover, the paths leading to online academic dishonesty are significantly supported with a 38.6 percent coefficient of determination. Other significant findings have practical implications for theory and practice in higher education, particularly in online assessment. These insights indicate that educational leaders must recognize the need for targeted interventions to promote ethical behavior and uphold academic integrity. Educators and policymakers can use these insights to develop measures addressing online academic dishonesty.

ABSTRACT:
This study mainly investigated the perceived level of vocabulary development of the students watching English/Filipino movies with English subtitles. Moreover, the relationship of variable accessibility to variables knowledge acquisition and attitude and the relationship of these three variables to vocabulary development were also determined. Four hundred fifty first-year students of a state university in the Philippines served as respondents in this study. Each student answered a survey questionnaire with a total of 23 items that detail their perception of using English/Filipino movies with English subtitles as a tool for developing their vocabulary. The overall perceived level of significance of the three variables showed positive results. Furthermore, the results extracted from Partial Least Squares Structural Equation Modeling (PLS-SEM) indicated that accessibility has a significant relationship to knowledge acquisition and attitude. Additionally, all three variables were found to affect vocabulary development. The study ascertained the significant relationship between English/Filipino movies with English subtitles and the underlying variables attached to the students’ vocabulary development.

ABSTRACT:
This study contends that the Maranao people’s induction into the Tausug community of the Sulu aquapelago in the Philippines – an induction supervised by the colonial state – exemplifies a case of dialectical insularity or aquapelagicity in the production of a unique islandic identity that evolves through the deconstruction of Ramayan legends within templates of Darangen mythology. While numerous studies explore the role of myths and cultural narratives in reshaping and reinterpreting the identities of Muslim Filipinos, there is a notable scarcity of research specifically addressing how the Maranao community articulates its desired aquapelagic identity, particularly in the context of the ‘piratical’ movements and global commerce from the 16th to 18th centuries. Employing an interdisciplinary critical methodology, the study investigates how these reimagined myths provide affective sustenance for the Maranao’s imagined community, despite their, arguably, limited awareness of the Ramayan’s Indic, Hindu, and Puranic origins. The Maranao’s distinctive focus on Ravan (who is otherwise typically viewed as the Ramayan’s anti-hero in mainstream Indian interpretations) serves as a prominent index of their political praxis characterised by a unique affective dimension in their identity within Filipino cultures, the Malay Archipelago, and the larger Southeast Asian legacy of the Ramayan. This affective – or what I view as an aquapelagic – reinterpretation of the Ramayan within Maranao culture parallels the Tausug’s self-representation, characterised by ‘piratical’ assertions of their ‘Muslimness’ and their political stance on the Sabah dispute. This occurs within a decolonial framework that unveils the identity of the archipelago as an aquapelago, encompassing the marginal voices that shape its emancipatory future. Eventually, this constitutes a resistance to cultural and psychological erasure by colonial legacies – a resistance that influences the ongoing discourse of preserving unique political identities in the Malay archipelago and the wider Southeast Asian region.

ABSTRACT:
The internationalization of higher education has become an increasingly important topic in academic research, as evidenced by a systematic review of 1,412 articles published over the past 25 years. Key themes surrounding this phenomenon include mobility, knowledge transfer, and cooperation, alongside competition, national strategies, and the mutual influence of higher education systems. The globalization of the economy has created pressures on academics, students, and university administrators, with challenges such as inadequate research funding and technological limitations. In response, universities have sought partnerships and alternative funding sources to enhance student and faculty mobility and foster research collaboration. This study builds on the work of Moshtari and Safarpour (2024), who identified key issues faced by East African countries in higher education, by exploring similar challenges in Southeast Asia, specifically the Philippines. These challenges are categorized into four main areas: i) policy; ii) financial and physical resources; iii) academic competencies; and iv) social and cultural factors. Additionally, our research proposes an agenda for success that includes the following dimensions: i) international engagement and mobility; ii) internationalization of the curriculum; iii) research collaboration; iv) reputation building; and v) fostering a research culture focused on innovation.

ABSTRACT:
This research assessed the acceptability and effectiveness of Interaction-based activities in teaching speaking to propose appropriate enhancements. It utilized two instruments – Interaction-based Activities and the Acceptability Survey Questionnaire. The Descriptive normative survey, which involved the analysis of the Interaction-based Activities in its acceptability through the Acceptability Survey Questionnaire and effectiveness in developing students’ communicative performance through the 49 student-respondents, was utilized in this research. The findings using the Interaction-based activities through the statistical treatment of Pearson r showed that the student’s performance in communicative and discourse competence is approaching proficiency, and strategic competence is proficient. On the other hand, the four aspects of the Interaction-based activities’ acceptability level, as perceived by the student respondents, received an acceptable response. Moreover, a moderate positive correlation exists between learners’ performance and their perceived acceptability level. The following conclusions are capsulized based on the findings: Interaction-based activities using Jose Garcia Villa’s select poems are accepted and can be improved for utilization to develop learners’ performance in discourse and strategic competence anchored on Lev Vygotsky’s Interactionist Theory and Canale and Swain’s Communicative Competence Theory. Based on these findings and conclusions, it is recommended that enhanced interaction-based activities be utilized to refine Grade VII learners’ communicative competence.

ABSTRACT:
Integrating artificial intelligence into teaching practices has become a prominent topic in recent literature, raising concerns about how teachers’ moral ascendancy and dependency can be attributed and measured in a behavioral context. This study addresses this gap by developing and validating the teachers’ perceived moral ascendancy and dependency on the AI integration (MAD-AI) scale. The methodological process involved the following key steps: initially identifying the scale’s dimensionality and creating draft items through a literature review; conducting validation with four experts; revising items based on expert feedback; holding two focus group discussions with six pre-service and four in-service teachers; refining dimensions and items based on these discussions; and finally, establishing the psychometric properties of the scale through exploratory factor analysis and confirmatory factor analysis with 383 survey responses from 224 in-service and 159 preservice teachers in the Philippines. The final 30-item MAD-AI scale for teachers includes two dimensions for moral ascendancy: (a) ethical transparency and accountability (7 items) and (b) professional integrity (8 items), as well as two dimensions for dependency: (a) institutional support (8 items) and (b) educator preparedness (7 items). Results demonstrated acceptable fit measures, strong reliability, convergent validity, and discriminant validity, supporting the structural soundness of the scale.

ABSTRACT:
With the introduction of virtual reality, the education sector has increasingly integrated this technology into the teaching and learning process. This paper analyzes the perspectives of pre-service teachers on integrating virtual reality in the select contents of world history and geography subjects within the social studies curriculum of a higher education institution. The research employs the Concurrent Triangulation Design methodology. It involves 41 survey respondents and 16 Focus Group Discussion participants who are pre-service social studies teachers from a state university in the Philippines. The findings reveal three significant outcomes: firstly, integrating virtual reality into world history and geography subjects enhances the perceived competence of pre-service teachers. Secondly, these pre-service teachers strongly advocate incorporating virtual learning experiences into teaching world history and geography subjects. However, a third important finding highlights the challenges associated with implementing virtual reality, including the need for increased budget allocation to purchase VR headsets and software subscriptions and mitigate the discomfort experienced by the participants while using the headsets. These challenges underscore the importance of considering resource allocation and technological infrastructure since this study was conducted in a government-funded institution of a developing economy where the budget is limited. Finally, this paper emphasizes the potential benefits and practical considerations of integrating virtual reality technology into the social studies curriculum, overcoming traditional methods by creating unique immersive learning experiences.

ABSTRACT:
This study explored the survival mechanisms of Badjao migrants in Mambaling, Cebu City. It also examined how they respond to the different challenges they encounter in their daily lives, specifically the perceived discrimination from society, and how the government and other private sectors have helped them improve their lives. This research utilized a naturalistic inquiry method and purposive snowball sampling to identify and understand the survival mechanisms of Badjao migrants. The study involved 10 key informants who were asked to answer a questionnaire and participate in interviews. The results revealed that their survival mechanisms include fulfilling physiological needs, security, love and belongingness, esteem needs, and self-actualization. These mechanisms have evolved over time due to migration. Their lives in the city have provided them with various survival strategies to thrive despite their limitations and the social discrimination they have faced. Additionally, the support from local government units and various private organizations has helped them gain better opportunities in life. In conclusion, migration has had a major influence on the lives of the Badjao migrants in Mambaling. As a result of these influences, they have developed alternative strategies and survival mechanisms to support their daily existence. However, life remains a struggle for them. While they maintain a strong sense of community, fulfilling all their needs is not easy.

ABSTRACT:
This study applies the Technology Acceptance Model (TAM) to evaluate the factors influencing the adoption of pneumatic precision planters in corn farming in the Philippines. Data from 393 farmers were analyzed using Partial Least Squares Structural Equation Modeling (PLS-SEM) to examine the relationships between Perceived Usefulness (PU), Perceived Ease of Use (PEU), Behavioral Intention (BI), and three extended TAM constructs: Compatibility (CO), Observability (OB), and Personal Innovativeness (PI). The model was validated for reliability and discriminant validity, with the Average Variance Extracted (AVE) ranging from 0.664 to 0.823. Statistical significance was observed in ten out of twelve hypothesized relationships, indicating a high likelihood of adoption. This study extends TAM by incorporating external factors such as CO, OB, and PI, offering a deeper understanding of how these variables influence farmers’ perceptions of the technology’s usefulness and ease of use. The findings suggest that, for successful adoption, policymakers should focus on enhancing the visibility of the technology’s benefits, ensuring compatibility with existing farming practices, and promoting openness to innovation through targeted education and support. The results highlight the need for practical interventions, such as educational programs and demonstration projects, which could significantly improve technology adoption, productivity, and sustainability in Philippine agriculture.

ABSTRACT:
Integrating the Internet of Things (IoT) in STEM education has gained attention for its potential to transform traditional teaching and learning. The paper reviews and examines the challenges and opportunities of incorporating IoT into STEM curricula, following the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines. An initial Web of Science (WoS) and Scopus search identified 1,014 records. After removing duplicates (159), non-English sources (3), book series (261), conference proceedings (243), systematic review papers (70), and studies lacking relevance (254), only 24 articles met the final inclusion criteria. The review reveals seven key challenges to IoT integration: resource limitations, skill gaps, lack of standardized curriculum, data security and privacy concerns, integration with existing systems, effectiveness, and reliability. Conversely, seven opportunities were identified, including adaptive and hands-on learning, actionable STEM education, improved problem-solving skills, innovation and creativity, industry alignment and career readiness, real-time data analysis, and global connectivity. These challenges and opportunities were grouped into five themes: personnel management, IoT infrastructure, financial considerations, skill alignment, and educational administration. We offer policy insights derived from the identified challenges and opportunities of integrating IoT into STEM education.

ABSTRACT:
This study investigated the preferred oral corrective feedback (OCF) strategies of Filipino ESL preservice teachers at a Philippine State University. Grounded in Krashen’s Input Hypothesis, it aimed to identify learners’ preferences to improve language instruction. A mixed-methods approach was employed, involving 192 preservice teachers from six academic majors—Mathematics, English, Science, Social Studies, Technology and Livelihood Education, and Elementary Education—enrolled in a Purposive Communication course. Data was gathered through surveys and interviews using a 6-point Likert scale, where 1 indicated strongly disagree and 6 indicated strongly agree. Quantitative analysis involved ANOVA to compare preferences across majors and T-tests to assess gender-based differences. Thematic analysis was applied to qualitative responses. The study identified the most preferred OCF strategy during oral examinations and examined whether preferences differed by academic major or gender. Results showed that private feedback was most preferred, with no statistically significant differences across majors or genders. These findings highlight the value of individualized feedback and may help educators and policymakers develop more learner-centered language teaching approaches. Previous research also emphasizes the influence of learners’ proficiency levels on feedback preferences, reinforcing the need to tailor corrective strategies to individual needs for more effective instruction.

ABSTRACT:
Tourism provides socio-economic benefits, enhances environmental protection, and improves the well-being of rural communities. This study assessed the sustainability of selected tourism sites in southwestern Cebu to inform the development of a tourism sustainability plan. A descriptive research design was employed, using two researcher-designed questionnaires to gather data from 60 community members and 25 tourists selected through random sampling. Data were analyzed using frequency, percentage, weighted mean, Chi-square Test of Independence, and One-Way ANOVA. Findings revealed that both groups perceived financial and manufactured capital as sustainable, while social and human capital were moderately sustainable, and natural capital was less sustainable. Aesthetic appeal, facilities, accessibility, and visitor experience were rated excellent, while customer service and value for money were rated good. Significant relationships were found between respondents’ demographics and their perceptions of sustainability, with differences observed between community members and tourists in their assessment of financial, natural, and manufactured capital. The study recommends implementing a tourism development plan that prioritizes environmental conservation, service improvements, and equitable economic opportunities for local communities while maintaining high-quality tourism facilities.

ABSTRACT:
Micro and small enterprises managed by women are the pillars of a country’s economy in developing countries. These micro enterprises face many challenges: hostile business environment, difficult-to-obtain financing, lack of effectiveness of networks, recognized to contribute to survival and growth. This chapter aimed at a better understanding of the reality of micro enterprises, facing stereotypes on women’s capacity to manage and cultural negative influence. Despite these constraints, those women taking risks and with innovative spirit succeed. More specifically, this research seeks to verify hypotheses from the literature on facilitators and deterrents of their perceived financial performance. The role of micro-financing is often found useful.

ABSTRACT:
The purpose of this study was to examine the effects of various forms of collaborative training on embedded students’ metacognitive skills and their capacity to make sociotechnical decisions within an artificial intelligence classroom environment. Part of making decisions in the social science involves both identifying problems and developing, testing, and ultimately settling on solutions. Using the IMPROVE methodology, we compared two distinct collaborative training approaches, each with its own set of embedded metacognitive instructions. Two hundred and fifty-three diploma students from three separate colleges took part: one in a conventional setting of collaborative learning (COLED), another with embedded metacognitive questions (COLED+EMB), and a control group that did not undergo any intervention. In comparison to the control group, students in the two training situations performed better on both measures of sociotechnical decision making. Regardless, there was no difference in performance between the COLED and COLED+EMB conditions for the students. The learning outcomes on the regulatory component of metacognition improved with time in all settings. Students in the COLED+EMB condition had the best average performance on the posttest, although this finding was not statistically significant. The possible outcomes of introducing metacognitive training into science classes are the focus of the conversation.

ABSTRACT:
Optimizing feature selection to capture temporal dynamics and seasonal variations enhances the accuracy of multivariate load forecasting models. Careful consideration of factors like temperature fluctuations effectively models load behavior and improves forecasting robustness. The paper uses a multivariate forecasting model with fractal-fuzzy feature selection to enhance predictive accuracy by focusing on key and influential features. Performance is evaluated through statistical techniques, including paired t-tests and one-way ANOVA, to test null hypotheses regarding model performance differences before and after feature selection. We applied our method using multivariate data from CEBECO and PAGASA to forecast peak energy demand based on meteorological factors. The temperature-related variables achieved an FFCC≈0.99, indicating their strong influence on demand variability. As the parameter α increases, the importance of temperature features grows, while the relevance of rainfall and wind speed decreases. The paper shows that using selected features improves computational efficiency while maintaining accuracy. Feature selection reduced average training times from 25.58 seconds to about 5 to 10 seconds, significantly enhancing processing speed compared to models with the full feature set. Experimental results demonstrate that the fractal-fuzzy feature selection approach improves the predictive accuracy of forecasting models. Key environmental variables, particularly temperature, significantly enhance peak electricity demand predictions. The paper explores how weather affects energy consumption and suggests that better forecasting models can improve energy management by integrating fractal and fuzzy logic to select external factors to include in the forecasts.

ABSTRACT:
Traditional feature selection methods often overlook complex feature interactions and fail to capture variability and uncertainty in feature contributions, leading to potentially misleading conclusions about their influence. The paper presents a framework that generates triangular fuzzy weights for each feature based on importance scores of PCA (Principal Component Analysis). This approach captures uncertainty and variability. It applies a Mandelbrot fractal transformation to the fuzzy decision matrix, modeling the complex interactions between climate features and peak demand while emphasizing critical influences. Additionally, it creates a fuzzy fractal matrix to adjust feature contributions according to fractal principles. We also established the Fuzzy Fractal Closeness Coefficient (FFCC), integrating PCA-explained variance and introducing an adaptive parameter for dynamic weighting, which recalibrates the fractal influence and FFCC to measure closeness to ideal solutions, resulting in an interpretable closeness score. To apply the method in a real-world setting, we used multivariate data from CEBECO and PAGASA to predict peak demand from weather features. After applying the approach, the temperature-related variables yield FFCC≈0.99 to the most critical contributors to variability in peak energy demand. For instance, in energy demand forecasting, the paper demonstrates that temperature-related features (TMAX, TMIN, TMEAN) gain stronger influence as α increases, while the relevance of rainfall and wind speed diminishes. The balance of the deterministic structure of fractal influence with the flexibility of fuzzy reasoning yields robust feature selection.

ABSTRACT:
The Philippines aims to achieve a 50% renewable energy (RE) share in its electricity mix and a 24 % economy-wide energy savings by 2040, requiring substantial advancements in the power sector and electricity market. Renewable energy (RE) integration in the Philippines continues to expand as the country aims for a more sustainable and secure energy future. However, the variability of RE is driven by weather conditions and technological limitations, which challenge maintaining stable electricity prices and a reliable supply. Electricity pricing models must evolve to address these disruptions in the market. While RE reduces dependence on fossil fuels, it can also increase price volatility and financial risk if not managed properly. To respond to these challenges, pricing mechanisms such as Real-Time Pricing (RTP), Locational Marginal Pricing (LMP), and Renewable Energy Certificates (RECs) can help improve market efficiency and investment signals. To support these innovations, collaboration between government, regulators, industry, and academia is essential to modernize pricing structures, strengthen grid operations, and promote long-term energy sustainability.

ABSTRACT:
The use of artificial intelligence (AI) in mathematics teaching emphasizes the necessity for future educators to develop digital literacy (DL) and AI literacy (AIL). Despite increasing attention being paid to these competencies, little is known about how DL influences AIL among pre-service mathematics teachers. A descriptive correlational research design was used in this study to assess the levels of DL and AIL, explore their relationship, and profile participants based on gender and year level. Teachers (AILST)instruments, including the Digital Literacy Scale and AI Literacy Scale for Teachers (AILST), measured four AIL dimensions: perception, knowledge and skills, application and innovation, and ethics. Digital literacy was evaluated concurrently. The data were analyzed using IBM SPSS Statistics (version 21). Descriptive statistics (means and standard deviations) summarized overall literacy levels. To determine relationships, Pearson’s r was used to assess the correlation between digital and AI literacy, Spearman’s rho examined associations with year level, and the chi-square test explored the relationship between gender and literacy variables. Results showed that pre-service teachers had above-average competence of DL and AIL, with a moderate positive correlation between the two, indicating that greater digital fluency supports stronger AI-related competencies. However, notable gaps persist in applying AI for innovation and in critically evaluating AI-generated content. These findings indicate the need to integrate DL and AIL in teacher education programs to prepare aspiring mathematics educators for ethical, effective, and innovative AI use in classrooms, thereby contributing to research-informed instructional practices and responsive curriculum development.

ABSTRACT:
This study investigates the influence of land use and land-cover changes on water quality within the Mananga River Watershed Reserve, Metro Cebu, Philippines, over three distinct time periods: 2010, 2015, and 2020. The watershed supplying around 40% of Metro Cebu’s water found significant land-use shifts due to urban expansion and declining forest areas. Using geographic information system-based analysis, the research correlates land cover data with water quality parameters. It identifies brushlands/shrubs, perennial crops, annual crops, and built-up areas as dominant land uses. Findings show perennial crop areas correlate positively with dissolved oxygen levels, while grasslands are linked to higher nitrate levels, indicating agricultural pollutants. Closed and open forests are vital for water quality, showing negative correlations with various pollutants. The study links forest cover loss and increased built-up areas to poorer water quality, threatening crucial sources like the Jaclupan Dam. This is the first study to quantify land-use change impacts on water quality in Metro Cebu, providing key insights for urban watershed management. Recommendations include sustainable land management practices such as enrichment planting, preventing encroachment, promoting organic farming, and implementing soil and water conservation technologies. Limitations related to topography and agricultural practices’ influence on water pollution are acknowledged.

ABSTRACT:
Tourism provides socio-economic benefits, enhances environmental protection, and improves the well-being of rural communities. This study assessed the sustainability of selected tourism sites in southwestern Cebu to inform the development of a tourism sustainability plan. A descriptive research design was employed, using two researcher-designed questionnaires to gather data from 60 community members and 25 tourists selected through random sampling. Data were analyzed using frequency, percentage, weighted mean, Chi-square Test of Independence, and One-Way ANOVA. Findings revealed that both groups perceived financial and manufactured capital as sustainable, while social and human capital were moderately sustainable, and natural capital was less sustainable. Aesthetic appeal, facilities, accessibility, and visitor experience were rated excellent, while customer service and value for money were rated good. Significant relationships were found between respondents’ demographics and their perceptions of sustainability, with differences observed between community members and tourists in their assessment of financial, natural, and manufactured capital. The study recommends implementing a tourism development plan that prioritizes environmental conservation, service improvements, and equitable economic opportunities for local communities while maintaining high-quality tourism facilities.

ABSTRACT:
Addressing the global shortage of qualified math and science teachers is a serious challenge, especially for developing countries that are losing skilled educators to jobs overseas. The paper examines the factors influencing career aspirations among preservice teachers in mathematics and science, an area that has received limited focused investigation. Using covariance-based structural equation modeling (CB-SEM), the proposed model examines how motivation, social influence, professional identity, and decision self-efficacy contribute to career decidedness, subsequently informing career aspirations. Data were collected from 615 mathematics and science preservice teachers enrolled in teacher education institutions across the Visayas region of the Philippines. The CB-SEM results revealed three key findings: (a) motivation significantly predicts teaching career aspirations, (b) career decidedness has a strong direct positive effect on the intention to pursue teaching, and (c) preservice science teachers demonstrate stronger links between motivation, decisional self-efficacy, and career decidedness compared to their mathematics counterparts. These findings have implications for teacher education policy programs aimed at strengthening aspirations, recruitment, and retention in mathematics and science teaching professions.

ABSTRACT:
This study examines the relationships among sustainability competencies, institutional support, environmental awareness, and behavioral intentions among university students at Cebu Technological University–Danao Campus. Guided by the Theory of Planned Behavior and Social Cognitive Theory, this cross-sectional study collected data from 315 randomly selected students through a structured questionnaire using a five-point Likert scale, designed to measure each construct with validated items adapted from prior studies. Data were analyzed using Structural Equation Modeling (SEM) to test the hypothesized relationships and assess model fit. Results showed strong institutional support (Mean = 4.23, SD = 0.56) and high behavioral intentions toward sustainability (Mean = 4.25, SD = 0.52). Sustainability competencies (Mean = 4.13, SD = 0.60) did not have a significant direct effect on environmental awareness (β = 0.03, p = 0.740) but had a strong positive effect on institutional support (β = 0.45, p < 0.001). Institutional support significantly influenced environmental awareness (β = 0.52, p < 0.001), which in turn positively impacted behavioral intentions (β = 0.67, p < 0.001). These findings indicate that institutional support mediates the relationship between sustainability competencies and environmental awareness, ultimately enhancing behavioral intentions. Based on these results, the study recommends strengthening institutional policies and programs to support sustainability education and initiatives, as such support plays a critical role in translating competencies into increased environmental awareness and sustainable behaviors among students.

ABSTRACT:
Dissolved Gas Analysis (DGA) is a practical, non-intrusive test to check transformer health status, as it is widely used in the field. However, the traditional methods of DGA based diagnostics have intrinsic weaknesses. For example, the Rogers ratio method is limited only to gases involved in the computation. The interpretation of the IEC Ratio method can be unknown at some point. The Duval triangle method cannot diagnose healthy degradation of oil from faulty ones. All traditional methods were subject to expert subjective judgment. To fill these gaps, this paper introduces the two-layer framework using a random forest algorithm with the IEEE C57.104 – 2019TM guide as a watchdog (layer 1) for unhealthy oil degradation versus normal ones. The prediction model (layer 2) used the random forest algorithm. Using the 277 DGA datasets from Distribution Utilities from different parts of the Philippines, the framework surpassed the accuracy of traditional methods (Duval triangle method, IEC ratio, Doernunberg method) with an accuracy of 100%. The Duval triangle got 98.92% accuracy, the IEC ratio had 28.32% accuracy, and the Doernunberg method had an accuracy of 27.50%. Other ML algorithms, such as ANN (MLP), K-nearest neighbors, SVM (linear), and J48, were also used for comparison. The ANN (MLP), K-Nearest neighbor, and SVM (linear) got 78.6%, 85.7%, and 78.6% accuracy, respectively. The random forest got the highest cross-validation score (89.14% ave.) among all ML methods. Further evaluations were used for J48, DT, and Random Forest since all got 100% accuracy. RF algorithm still got the highest PR-AUC (94%, 89%) and ROC AUC (95%, 97%) scores among the J48 and DT in the 70/30 and 80/20 data split.

ABSTRACT:
Creating conflict-free academic timetables that respect teacher availability, subject eligibility, and limited re-sources remains a persistent challenge in educational institutions. This study introduces a novel hybrid algorithm that combines Self-Organizing Maps (SOM), Secure Convex Dominating Sets (SCDS), and Genetic Algorithms (GA) to address this problem effectively. SOM is employed to cluster subjects based on teaching duration and eligibility, providing structured guidance in initial scheduling. SCDS identifies the most conflict-prone subjects—typically those with limited eligible teachers—and ensures they are prioritized, thereby reducing downstream bottlenecks. GA then iteratively refines the schedule by evaluating room assignments, teacher loads, and constraint satisfaction. Extensive simulation experiments were conducted under varying conditions, including worst-case scenarios with dense scheduling conflicts. The system achieved high success rates, particularly in moderate to complex settings, and demonstrated robustness even in constrained environments. Notably, SOM improved spatial and temporal coherence, while SCDS enhanced conflict resolution and GA enabled adaptive optimization. Runtime and convergence results remained within practical limits, with a time complexity of O(n2+gpn). The proposed hybrid framework balances structural prioritization and evolutionary refinement, offering a scalable and intelligent solution to the timetabling problem. It stands out by gracefully handling worst-case scenarios where traditional heuristics often fail.

ABSTRACT:
This paper presents a novel approach for sidewalk detection in urban environments using multi-scale feature fusion combined with adaptive edge enhancement techniques. The proposed method integrates a modified U-Net architecture with attention mechanisms and incorporates geometric constraints based on urban infrastructure characteristics. Our approach processes RGB images captured from vehicle-mounted cameras and pedestrian viewpoints to segment sidewalk regions with high accuracy. The multi-scale feature fusion module captures both fine-grained texture details and global contextual information, while the adaptive edge enhancement component refines boundary detection between sidewalks and adjacent surfaces. Experimental validation on a custom dataset of 5,000 urban images from various cities demonstrates that our method achieves a mean Intersection over Union (IoU) of 87.3% and an F1-score of 91.2%, outperforming existing state-of-the-art methods by 5.8% and 4.6%, respectively. The approach shows robust performance across different lighting conditions, weather scenarios, and urban layouts, making it suitable for real-world applications in autonomous navigation systems and accessibility planning tools.

ABSTRACT:
This paper examines unregulated pricing practices targeting foreign tourists, revealing that local tourism markets suffer more severe damage than international markets through cross-market contagion mechanisms. Using integrated system dynamics and agent-based modeling validated with 92% accuracy against documented tourism crises, we analyze dual-market interactions under unregulated pricing scenarios over 10-year periods. Our simulation results reveal that local tourism arrivals decline by 76% compared to 44% for international tourism, with local satisfaction collapsing by 82% versus 63% for international visitors. Community support falls to 20%, and cultural authenticity drops to 32%, indicating a fundamental breakdown in sustainability. Recovery of local tourism requires 2-3 times longer than international recovery (15-35 versus 8-15 years) due to the need to rebuild community relationships. The study introduces cross-market contagion theory through three novel feedback loops: exploitation-reputation spiral, local tourism displacement loop, and cultural commodification accelerator. Policy intervention analysis demonstrates that integrated dual-market approaches achieve superior outcomes, with local tourism showing a 179% improvement under transparency measures compared to 39% for international tourism. These findings challenge traditional tourism economics by positioning local tourism as the foundational stability mechanism for destination competitiveness. The research establishes that effective pricing policies must explicitly protect both international and local market segments simultaneously.

ABSTRACT:
Taro (Colocasia esculenta) is a nutrient-dense root crop rich in dietary fiber, vitamins, and antioxidants, making it beneficial for digestive health and immune support. Despite taro’s nutritional benefits and abundance in tropical regions, its potential for value-added snack production remains underexplored, creating a significant research gap. The present study assessed the sensory attributes and acceptability of taro root kropeck. A quantitative experimental design was employed, incorporating five treatment formulations with varying ratios of all-purpose and taro flour: T1 (control-100% all-purpose flour), T2 (100% taro flour), T3 (50:50 all-purpose flour to taro flour), T4 (60:40 taro to all-purpose flour), and T5 (40:60 taro to all-purpose flour). Each formulation contained constant amounts of ground chicken and seasonings. Sensory evaluation was conducted using a structured questionnaire to assess color, crispiness, and flavor. Data was analyzed using descriptive statistics and mean comparison techniques. Key findings revealed that higher taro flour content significantly influenced the color, making it darker, with consumer preference leaning towards slightly brown and brown hues. Crispiness ratings across treatments remained within the “Liked Moderately” category, indicating that taro flour substitution did not negatively affect the texture. However, flavor acceptability varied, with formulations containing moderate taro flour levels (50% and 75%) receiving higher ratings. These findings imply that taro root kropeck is a viable snack alternative with potential commercial appeal. Further research may explore optimization techniques to enhance flavor while maintaining its nutritional benefits.

ABSTRACT:
Cassava (Manihot esculenta) and malunggay (Moringa oleifera) are widely cultivated in the Philippines and valued for their nutritional and health benefits. Cassava is a major source of carbohydrates and dietary fiber, while malunggay is rich in vitamins, minerals, and antioxidants. This study aimed to develop and evaluate cassava flour chips infused with fresh blended malunggay leaves as a functional, locally sourced snack that may help combat malnutrition. Three chip formulations containing different concentrations of malunggay leaves (¼ cup, ½ cup, and ¾ cup) were prepared. Sensory evaluation was conducted with 30 food experts and 70 consumer panelists, using a 5-point hedonic scale to assess aroma, color, taste, and texture. Data were analyzed using analysis of variance (ANOVA). Results showed that all formulations were generally acceptable, but F1 (¼ cup malunggay) obtained the highest overall scores (aroma = 3.91 ± 0.86, color = 3.70 ± 0.94, taste = 4.00 ± 0.82, texture = 3.85 ± 0.89). Significant differences (p < 0.05) were observed among formulations in taste and texture, indicating that higher malunggay content slightly reduced acceptability. The study demonstrates the novelty of integrating malunggay into cassava-based snack products, providing both enhanced nutritional value and consumer acceptability. This work highlights the potential of cassava–malunggay chips as an affordable, nutritious, and sustainable food innovation that can support public health and local agricultural development.
