ChatGPT has gained popularity among Philippine educational institutions due to its versatility and usefulness in academic activities. However, educators have raised concerns about the ethical issues, academic dishonesty, and technology dependence associated with its use. This study aimed to develop and validate an instrument called KAP-CQ39 that assesses the knowledge, attitudes, and practices of preservice...

S-invariant Termwise Addition of Reactions Via Reaction Vector Multiples (STAR-RVM) Transformation
Interest in connecting Chemical Reactions Network Theory (CRNT) and evolutionary game theory (EGT) arise viewing the tools of network in the analysis of evolutionary games. Here, the evolution of population species is studied as a biological phenomenon and describing the rate of such changes through a replicator system becomes a focus. A set of polynomial...
Assessing the Compliance of a Coastal Municipality to the Ecological Solid Waste Management Act of 2000 (RA 9003)
To bring about a significant change in the SWM situation in the Philippines, the Ecological Solid Waste Management Act of 2000 (RA 9003) was enacted to provide local government units with frameworks that would help them solve the looming garbage problem in the country. Despite the presence of the decree, managing wastes remains a problem...
On the j-Edge Intersection Graph of Cycle Graph
This paper defines a new class of graphs using the spanning subgraphs of a cycle graph as vertices. This class of graphs is called j-edge intersection graph of cycle graph, denoted by EC(n,j). The vertex set of EC(n,j) is the set of spanning subgraphs of cycle graph with j edges where n≥3 and j is a nonnegative integer such that 1≤j≤n. Moreover, two distinct vertices are...
Automated Computer-Aided Detection and Classification of Intracranial Hemorrhage Using Ensemble Deep Learning Techniques
Diagnosing Intracranial Hemorrhage (ICH) at an early stage is difficult since it affects the blood vessels in the brain, often resulting in death. We propose an ensemble of Convolutional Neural Networks (CNNs) combining Squeeze and Excitation–based Residual Networks with the next dimension (SE-ResNeXT) and Long Short-Term Memory (LSTM) Networks in order to address this issue....
Distribution and Management of the Invasive Swietenia macrophylla King (Meliaceae) at the Foot of a Protected Area in Luzon Island, Philippines
Invasive alien plant species (IAPS) pose one of the most significant threats to native biodiversity. Swietenia macrophylla, or big leaf mahogany, is among the most threatening invasive plants in the Philippines. This article aimed to formally document the presence of S. macrophylla along the edges of Mt. Banahaw de Nagcarlan, a protected area on Luzon Island, Philippines. The...
Formulated Hand Sanitizer Utilizing Passion Fruit (Passifloraedulis) Leaf Extract as an Active Ingredient
Passiflora edulis leaf extracts were added as an active ingredient for alcohol-based hand sanitizer (ABHS). Matured leaveswere air-dried, powdered, and soaked in methanol (1:10, w/v) for 24 hours. The solvent-free crude extract was used toformulate hand sanitizer utilizing varying amounts of leaf extract (1,3 and 5% w/w). The antimicrobial activities of the leafextracts and the...
Design of Patient Specific Hip Prosthesis based on Finite Element Analysis: A Comparative Study
This study aims to develop a patient-specific hip implant for osteoarthritis conditions and to compare with intact and conventional implant. The femoral bone with head and shaft region was segmented from the pelvic griddle and converted into 3D model. The parameters such as femoral ball diameter, shaft length, acetabular cup diameter, and neck angle were...
A 2xVDD digital output buffer with gate driving stability andnon-overlapping signaling control for slew-rate auto-adjustment using16-nm FinFET CMOS process
This paper presents a 2 × VDD mixed-voltage digital output buffer where its slew rate (SR) is automatically adjusted based on PVT (process, voltage, and temperature) detection. The developed buffer is the first to be fabricated using TSMC 16-nm CMOS Logic FinFET Compact (Shrink) LL ELK Cu 1P13 M process. Since slew rate is one...
A 1.0 fJ energy/bit single-ended 1 kb 6T SRAM implemented using 40 nm CMOS process
An ultra-low-energy SRAM composed of single-ended cells is demonstrated on silicon in this investigation. More specifically, the supply voltages of cells are gated by wordline (WL) enable, and the voltage mode select (VMS) signals select one of the corresponding supply voltages. A lower voltage is selected to maintain stored bit state when cells are not...
