This study aims to determine the demographic, epidemiologic, and clinical characteristics of COVID-19 cases that are highly susceptible to COVID-19 infection, with longer hospitalization and at higher risk of mortality and to provide insights that may be useful to assess the vaccination priority program and allocate hospital resources. Methods that were used include descriptive statistics, nonparametric analysis, and survival analysis. Results of the study reveal that women are more susceptible to infection while men are at risk of longer hospitalization and higher mortality. Significant risk factors to COVID-19 mortality are older age, male sex, difficulty breathing, and comorbidities like hypertension and diabetes. Patients with these combined symptoms should be considered for admission to the COVID-19 facility for proper management and care. Also, there is a significant delay in the testing and diagnosis of those who died, implying that timeliness in the testing and diagnosis of patients is crucial in patient survival.

The present study describes the attempt to achieve the competencies of the Philippine K to 12 Science Program through thematic instruction. It seeks to address the challenges encountered by science teachers with the current curriculum design. The researchers used a thematic instructional model in giving classroom instruction. Two sets of pre-service teachers, taking part as facilitators and as observers, were purposely chosen in the study. The researchers used convergent mixed methods design in analysing the pre-service teachers' experience and observations in teaching through thematic instruction. Results revealed that the thematic instruction implemented in the study has the potential to address the challenges of the current K to 12 science curriculum in terms of design, lesson content, and implementation. Consequently, the results suggest that the thematic instruction design in the study can be used to help achieve the desired outcomes of the K to 12 Science Curriculum.

COVID-19 has disrupted the education system globally, leading education institutions to migrate into remote learning. This study on online learning readiness and competence was conducted among management students on their perceptions on the importance of, and the confidence level of their online learning competence factors. Using the Student Readiness for Online Learning (SROL) instrument, the results show that the students consider Technical Competence as very important and that they are somewhat confident with their online learning competence. Both perceptions of the importance of the online competence factors and competency levels significantly correlate with the students’ self-report of whether or not they have learned in the course. Among the eight online learning challenges, the students find the “lack of technical skills in using online learning” as the least challenging. This study concludes with the recommendations that pedagogical and technological interventions be pursued to address the inadequacies in the online teaching-learning process.

Traffic flow mismanagement is a significant challenge in all countries especially in crowded cities. An alternative solution is to utilize smart technologies to predict traffic flow. In this study, frequency spectrum describing traffic sound characteristics is used as an indicator to predict the next five-minute vehicle density. Sound frequency and vehicle intensity are collected during a thirteen-hour data gathering. The collected sound intensity and frequency are then used to learn three machine-learning models - support vector machine, artificial neural network, and random forest and to predict vehicle intensity. It was found out that the performances of the three models based on root-mean-square-error values are 12.97, 16.01, and 10.67, respectively. These initial and satisfactory results pave a new way to predict traffic flow based on traffic sound characteristics which may serve as a better alternative to conventional features.

The study aimed to develop a software application to capture tourist activity information, extract movement patterns from the dataset through sequential pattern mining (SPM), and visualize spatiotemporal movement. Tourist activity information was captured through crowdsourced trajectory movements by scanning unique QR (Quick Response) codes for each visited tourist spots. The AprioriAll algorithm was used to find frequent trajectory patterns on tourist visits. The resulting maximal k-sequences and their subsequences represent the recommended trip itinerary. The spatial and temporal movements were visualized through a flow map and a heat map, respectively. The directed edges in the flow map show the recommended sequence of tourist sites to visit. The heat map shows the density of tourist visits in different areas at time intervals. The application was validated with selected tour planning experts to verify functional suitability, usability, and acceptability. Experimental results show positive indicators that the application met the users’ expectations.

The paper introduced the concept of a fractal distribution using a power-law distribution. It proceeds to determining the relationship between fractal and exponential distribution using a logarithmic transformation of a fractal random variable which turns out to be exponentially distributed. It also considered finding the point estimator of fractional dimension and its statistical characteristics. It was shown that the maximum likelihood estimator of the fractional dimension λ is biased. Another estimator was found and shown to be a uniformly minimum variance unbiased estimator (UMVUE) by Lehmann-Scheffe’s theorem.

This study is about the generated electricity from wastewater using carbon electrodes with the absence/presence of salt bridge through the biofilm anode of the microbial fuel cell (MFC) technology. The three wastewater samples used were from a pond, an abaca pulp mill, and rice fields. Results showed that one of the abaca pulp mill treatments, using carbon rod electrodes with salt bridge presence, reached the highest mean voltage and current to 578.7 mV and 0.2022 mV, respectively. The study revealed that the number of sensible power generation days, from start to end of experimentation, has a significant difference between treatments. Throughout the 20-day fermentation process, a total count of 8.94x105 colony forming units (CFU) per ml was found and purified from the biofilm anodes from pond wastewater. Likewise, 9.14x105 CFU per ml isolates from the abaca pulp mill, and 1.65x106 CFU per ml isolates from the rice field.

This paper deals with 1) angle trisection, 2) Bhaskara’s first proof, and 3) Pythagorean theorem. The purpose of this paper is threefold. First, to show a new, direct method of trisecting the 900 angle using unmarked straight edge and compass; secondly, to show Bhaskara’s first proof of the Pythagorean theorem (c2 = a2 + b2) as embedded in this new, direct trisection of the 900 angle; lastly, to show the derivation of the Pythagorean theorem from this trisection of the 900 angle. This paper employs the direct dissection method. It concludes by presenting four points: a) the concept of trisectability as distinct from concept of constructability; b) the trisection of the 900 angle as really a new, different method; c) Bhaskara’s first proof of the Pythagorean theorem as truly embedded in this trisection of the 900 angle and; d) another way of deriving Pythagorean theorem from this trisection of the 900 angle.

A novel computer vision application is developed to measure the deflection of two-dimensional (2D) reinforced concrete structural members. Eight beam samples, with dimensions of 160 mm x 150 mm x 1400 mm are loaded and simulated under a four-point loading test until failure using a reaction framework machine. A camera is fixed at the center front view of the concrete beams to capture the deflection of the samples while testing. In each test, a dial indicator is installed and the maximum deflection is manually recorded. Based on the results, the maximum deflection values recorded by the proposed application obtained an average error of 18.38 % when compared to the manual measured results. This indicates that computer vision-based application can provide a beam-wide scale deflection performance, compared to the traditional point-based deflection reading. This study paves a new possibility of aiding manual measurements of concrete beams and all other structural studies.
开发了一种新的计算机视觉应用程序来测量二维钢筋混凝土结构构件的挠度。8个尺寸为160 mm x 150 mm x 1400 mm的梁样品在四点加载试验下加载和模拟,直到使用反应框架机失效。摄像机固定在混凝土梁的中心前视图,以便在测试时捕获样品的挠度。在每次测试中,安装一个刻度表,并手动记录最大挠度。根据结果,与人工测量结果相比,所提出的应用程序记录的最大挠度值的平均误差为18.38%。这表明,与传统的基于点的偏转读数相比,基于计算机视觉的应用可以提供波束范围的偏转性能。这项研究为帮助手工测量混凝土梁和所有其他结构研究铺平了新的可能性。

This study was conducted to determine the technical performance of a rice hull-fueled cabinet food dryer. Data gathered from the drying performance in terms of drying behavior, drying rate, and dryer heat utilization efficiency using cassava chips was analyzed through an experimental design. The study also evaluated fuel consumption, thermal conversion efficiency, energy use efficiency, heat utilization efficiency, temperature distribution and economic performance. Results indicated that the dryer's average fuel consumption and the thermal conversion efficiency is 11.19 kg/hr and 6.17%. While the energy use efficiency is 41.51%, and the dryer efficiency is 11.79 %. The moisture reduction of the rice hull-fueled dryer is 8.156 kg/hr, and the heat utilization efficiency is 41.51%. The break-even of using the dryer is ₱ 4.988/kg; if rented out at ₱ 59.86/hr, the payback period is 0.988 batch/hr.
