No full textThis study determined the physico-chemical and sensory qualities of wine from makopa (Syzygium samarangense) in terms of pH, total soluble solids (TSS), titratable acidity (TA), specific gravity, alcohol content, clarity, aroma, flavor, taste, and overall acceptability. Evergreen makopa fruits were collected from Eastern Samar and were prepared following standard procedures and underwent anaerobic fermentation for 45 days and aging for four months. A digital pH meter was used to determine pH, titration for TA, refractometer for TSS, hydrometer for specific gravity, and dichromate oxidation and redox titration for alcohol content. Thirty tasters composed of 23 students, four teachers, and three security guards served as sensory evaluators. Results showed that makopa wine had the following mean values: pH, 4.40; TA, 3.11 g/L; TSS, 14.47 °Brix; specific gravity, 1.05; and alcohol content, 8.61%. For the sensory qualities, the mean scores are 3.70 for clarity, described as slightly clear; aroma, 3.93, described as distinct makopa odor; flavor, 4.03, described as distinct makopa flavor; taste, 4.30, having a very desirable. The overall acceptability is 8.60, interpreted as extremely acceptable. Makopa fruit of evergreen variety is suitable for the production of fruit wine considered as off-dry wine due to its lower alcohol. It is recommended that other varieties be tested in winemaking, lengthen the aging period, and other local fruits, especially the exotic ones, can also be studied
TEACHERS\u27 LIVED EXPERIENCES OF USING DIGITAL AND REAL LABORATORY ACTIVITIES IN BIOCHEMISTRY
No full textThe main objective of the study is to describe and evaluate the use of digital and real laboratory activities on science teachers\u27 conceptual understanding and laboratory performance skills. Digital laboratory activities involved the use of videos and online quizzes through Schoology, a learning management system. In contrast, real laboratory activities employed actual conduct of the laboratory activities, use of laboratory performance evaluation sheets, preparation of written laboratory reports, group outputs, reflective journals, and interviews. This study employed the Plan-Do-Study-Act (PDSA) model utilizing a mixed-method approach. An intact class of in-service teachers (N=16) enrolled in the course Laboratory Teaching in Basic Science Course served as participants in this study. The impacts of the intervention on the teachers\u27 performance skills were based on the teacher-researcher observations throughout the intervention, teachers\u27 actual hands-on work, and the written reports, reflections, and narratives. Qualitative data showed that conceptual understanding and laboratory performance skills of the teachers were enhanced using digital and real laboratory activities. Specifically, comprehension and mastery of the content were enhanced with digital laboratory activities, additive skills, written communication skills, and critical thinking skills of the real lab. It also indicated that the teachers attitudes towards the activity were improved as they showed collaboration and active participation within the group. Overall findings indicate that the use of digital laboratory activities as part of the laboratory instructions provides learning and the real lab.

No full textWith the Coronavirus Disease 2019 (COVID-19) outbreak, closure of factories and manufacturing hubs produced a drastic effect on the production and labor sector. Through the previously going industrial revolution, additive manufacturing (AM), which is considered to be one of the disruptive technologies, must be looked into consideration and be studied for its applications as the new normal to comply with the current demand for manufacturing. It disrupts how the manufacturing process is done and the underlying factors that can be substantially reduced, such as time spent and resource consumption in manufacturing. This paper provides a review of worldwide trends and current local government initiatives in 3D printing (3DP). Policy recommendations are discussed with respect to the governing factors that must be considered under a new normal
A SYSTEM DYNAMICS APPROACH TO UNDERSTANDING THE COVID-19 (NOVEL CORONAVIRUS) PANDEMIC
No full textThe novel coronavirus disease (COVID-19) pandemic has caused an overwhelming impact on lives around the world. Countries around the world have scrambled to implement various control measures such as social distancing, community lockdowns, quarantines in varying degrees of stringency and success. This paper proposed the application of the system dynamics (SD) modeling framework to capture the complex relationships, feedbacks, and delays present in a disease transmission system so that policies may be developed to effectively target the issue. In this study, three common policies, namely social distancing, quarantine, and vaccination, were integrated into the basic flu model to assess which would be the most effective in mitigating the infection and identify the portion of the system it would be best to leverage actions on. Results revealed that policies that remove the possibility of transmission through quarantine and vaccination performed best in reducing the spread and consequences of the pandemic. This model may help policymakers evaluate potential policy alternatives, especially when responding to high-risk issues such as a pandemic

The first aim of this paper is to describe (a) the general characteristics of viruses, (b) the coronaviruses, and (c) SARS-CoV-2 virus. The second aim is to discuss the diagnostic tests used for the detection of SARS-CoV-2 and COVID-19. Since the virus is new, there is a need to disseminate information about viruses in general and SARS-CoV-2 in particular. The laboratory tests for the detection of the virus and the disease are likewise presented. Altogether, the pieces of information provided here can help various stakeholders make sound and prudent decisions to contain the disease and prevent further spread of the virus so that everybody will be able to live once again a normal lif
INNOVATING AN ELECTRONIC BODY-MASS-INDEX CALCULATOR (E-BMIC) FOR THE TECHNO-CHALLENGED COMPUTER APPLICATION USERS
No full textExisting Body-Mass-Index (BMI) calculators generate reports by data migration, or encoding analyzed nutritional data into the spreadsheet. Then, the user formats these reports according to the Organization’s specifications. In some cases, the user does manual computation and analysis, or the spreadsheets require additional coding and importation of growth standards. These knowledge and skills are beyond the capability of most end-users. This paper, therefore, aimed to innovate an electronic Body-Mass-Index Calculator (e-BMIC) for generating auto-formatted nutritional reports that are usable by even the techno-challenged end- user. The program was written in Visual Basic Application for Excel following the modified waterfall software design. Since it runs on personal computers and mobile devices, it is useful for health workers conducting field monitoring and reporting in rural communities. Its major distinct features are the following: (a) automatic calculation, generation, and formatting reports without data migration; (b) provision of management modules for data entry to allow users with limited Excel knowledge and skills; and (c) immediate display of an individual client’s nutritional status in the user-interface and worksheet. Based on accuracy and reliability, it generated error-free nutritional status reports for Eastern Samar Division of the Department of Education in the Philippines. It was assessed as excellent for usability and more likely to be recommended to users. However, the future of this application is intensifying its usability and capability while extending it for general purpose implementation

ETHEPHON TREATMENT FOR EARLY SPROUTING OF YAM (Dioscorea alata L.) TUBERS var. VU-2
No full textThis study was conducted to determine the effect of ethephon on the sprouting behavior of VU-2 yam tubers and to establish the most effective concentration and time of application of ethephon for early sprouting of yam tubers. The ethephon concentration of 500 mg/L was more effective when applied at one month after harvest (OMAH) in promoting early and high percentage and long sprouts while the delayed application (i.e., two months after harvest) resulted to delayed sprouting, low sprouting incidence, and production of short sprouts. Also, tubers applied with 500 mg/L ethephon immediately after harvest (IAH) reached 50% sprouting the earliest. The degree of sprouting, shriveling, and decay incidence was not significantly affected by the different concentration and time of application of ethephon
