Improving the Accuracy of RPA Image Classification in Vegetation Mapping of Magsaysay, Occidental Mindoro using RGB Indices, Canopy Heights, and Feature Importance Weighting

Abstract. Mapping vegetation cover is an important step in generating baseline data for various purposes such as smart agriculture, disaster and hazard monitoring, as well as risk assessment and planning. For this purpose, the use of Remotely Piloted Aircraft (RPA) has become prevalent in recent years as an efficient and cost-effective way of obtaining very-high-resolution images. However, it is limited by its lack of spectral bands used for discriminating between land cover classes, especially vegetation. An object-based approach was used due to its suitability with high-resolution input datasets, as it can recognize complex shapes and patterns aside from spectral characteristics. The drone images were segmented using optimal parameters to produce image objects which were subsequently classified through supervised learning using the Random Forest (RF) algorithm. This study incorporated non-conventional spectral indices that use RGB bands only, such as Triangular Greenness Index (TGI), Excess Green (ExG), and Tree-Grass Differentiation Index (TGDI), as well as the canopy height data derived from RPA photogrammetry to improve classification accuracy. To further improve model performance, appropriate band weights for segmentation were determined by running a RF classifier to obtain band importance values. Accuracy assessments reveal that using additional indices and heights improved the accuracy resulting in a 20% increase in the average f1-score, with the vegetation classes improving by a 25% increase in their f1-scores (8–41% improvement per class). Using the integration of band importance values as weights to the object-based segmentation slightly decreased accuracy values for the vegetation classes by an average of 0.04 in the f-1 score. The methods developed to improve the accuracy of RPA image classification make it more suitable for mapping vegetation.

Online Instruction in Science Pursued in a Selected National High Schools in Sablayan North Schools Division of Occidental Mindoro: Basis for a Proposed Model

The challenge of evolving meaningful classroom instruction in the tertiary level is faced with lots of constraints. A few of these are the inadequacy of textbooks and instructional materials and ineptness in the part of the teachers on the teaching methodologies/ approaches to use that impact knowledge and skills to the students; and importantly, appropriating technology and instituting initiatives to impact quality education. The concerns, so far, have not been fully addressed, hence, the researcher in his desire to enhance technology instruction has designed and developed a Proposed Online Interactive Work Plan Model, a syllabus-based and experienced and empirical-based Model instruction. It is in this context that this study is conducted since he believes, his proposed instructional tool will serve as a useful material for both teachers of science-technology and students of information communication technology subjects using online interactive approach. This study is descriptive in nature where 6 schools administrators and expert in the persons of school principals and science supervisor, and science coordinators; and 14 teachers of science; and 172 students, representing the three (3) material high school of Sablayan North of the Schools Division of Occidental Mindoro as respondents of the study.

Towards Sustainable Internet Service Provision: Analyzing Consumer Preferences through a Hybrid TOPSIS–SEM–Neural Network Framework

In our increasingly digital world, grasping consumer preferences for internet service providers (ISPs) is paramount. This study was conducted in Occidental Mindoro, Luzon, the Philippines, and surveyed 280 respondents across ten municipalities with 81 in-person and online questionnaires. The research focused on twelve latent variables: internet speed, assurance, tangibility, responsiveness, reliability, empathy, data privacy, service quality, value-added services, price, customer satisfaction, and customer loyalty. Methods such as Technique for Order of Preference by Similarity to Ideal Solution (TOPSIS), Structural Equation Modeling (SEM), and an Artificial Neural Network (ANN) were integrated for the analysis. The study utilized TOPSIS to rank ISPs based on Service Quality (SERVQUAL) parameters, followed by SEM to delve into variable connections affecting preferences, and through as ANN, consumer behavior and loyalty were predicted. The SEM–ANN results revealed that assurance, responsiveness, empathy, and data privacy directly impacted service quality. Moreover, a significant correlation was found between customer satisfaction and service quality, influencing further customer loyalty alongside pricing. By integrating these methodologies, the study provides a comprehensive understanding of ISP preferences and emphasizes service quality as the most significant factor in industry decision-making.

A disaster communication plan for Higher Education Institutions in the Island Province of Occidental Mindoro, Philippines

Natural disasters, as they impede development and exacerbate poverty, have been the foremost concern of developing countries such as the Philippines. With this, the Philippine Disaster Risk Reduction Management Act (RA 10121) highlights the role of Higher Education Institutions (HEIs) in disaster resiliency and requires the incorporation of disaster communication in their institutions. Since disaster communication is considered to be one of the most valuable assets during disasters, academic institutions are provided visibility, credibility, and concrete direction to address chaos and confusion and to secure the safety of their stakeholders. The study created Safeguard Against Natural Disasters of Academes Through Actions (SANDATA), a disaster communication plan for HEIs in Occidental Mindoro to provide disaster communication strategies that can be used by them in securing a disaster-resilient academic environment. The output of this study was materialized using factor and thematic analysis and through the 300 respondents assigned for the quantitative data and 30 respondents assigned for the qualitative data. These findings influenced the disaster communication strategies employed by HEIs under the disaster stages of the Crisis Emergency Risk Communication (CERC) Theory, stakeholders' identified communication challenges as experienced by them, and their recommendations for improving the existing strategies of their institutions.
