The city of Tacloban in Eastern Visayas, Philippines is prone to various natural hazards particularly floods, storm surges, and landslides. During disasters, government facilities are converted into evacuation centers. This study was conducted to assess the evacuation centers in Tacloban City if they are found within the natural hazard zone or multi-hazard prone areas as based on the thematic maps provided by the national government, particularly the Disaster Risk Reduction and Management Office in the country. The study used the Geographic Information System (GIS) spatial analysis. The thematic natural hazard maps that were used to overlay were flooding, storm surges, and landslides. The study showed that Tacloban City is prone to three natural hazards. The result further indicated that there were 97 identified evacuation centers in the city, and most of the evacuation centers are schools and public buildings. Most of them are found in low lying areas which are prone to flooding and storm surge. Some are found in landslide-prone areas which are highly risky. &nbsp;Few evacuation centers are found in the landslide and flood-prone areas. However, there are three evacuation centers located in three natural hazard-prone areas. &nbsp;In conclusion, there could be community folks that are at risk of natural hazards even if the government had placed them in evacuation centers and facilities. It is suggested that the government must thoroughly evaluate target areas where evacuation centers are to be built.</p> Gabino Hilvano Copyright (c) https://journal.evsu.edu.ph/index.php/itmj/article/view/ITMJ-01012018 Mon, 01 Jan 2018 00:00:00 +0800 INNOVATING AN ELECTRONIC BODY-MASS-INDEX CALCULATOR (E-BMIC) FOR THE TECHNO-CHALLENGED COMPUTER APPLICATION USERS https://journal.evsu.edu.ph/index.php/itmj/article/view/35 <p>Existing 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.</p> Evelyn Cardoso Copyright (c) https://journal.evsu.edu.ph/index.php/itmj/article/view/35 Mon, 01 Jan 2018 00:00:00 +0800 PRODUCTION PERFORMANCE OF NATIVE CHICKEN (Gallus gallus domesticus ) SUPPLEMENTED WITH FERMENTED GOLDEN APPLE SNAIL (Pomacea canaliculata Lamark) EXTRACTS https://journal.evsu.edu.ph/index.php/itmj/article/view/36 <p>The study was conducted to assess the potential of golden apple snail extracts as supplemental feed for native chicken. Using the Randomized Complete Block Design, the results revealed that there is a significant difference among treatments in terms of body weight. In a mixture of T1 got the highest in terms of body length followed by T2 and lastly is T0. The results on shank length and wingspan showed no significant difference, but it is an important economic trait of chicken to improve through continuous intense selection pressure on this trait under domestication. The average feed consumption and average body weight showed a significant difference and feed conversion efficiency resulted in no significant difference. This means that supplementation of golden apple snail has a great potential in the production of native chicken.</p> Francisco Buctot, Jr. Copyright (c) https://journal.evsu.edu.ph/index.php/itmj/article/view/36 Mon, 01 Jan 2018 00:00:00 +0800 SIMULATION MODEL OF EXOTHERMIC REACTIONS FOR HEAT LOSS MITIGATION ON STEAM PIPES https://journal.evsu.edu.ph/index.php/itmj/article/view/38 <p>Applying exothermic reaction to steam pipes to mitigate heat loss is an idea that is yet to be explored. By using simulation modeling, this paper focuses on gathering theoretical data to serve as the baseline for the actual application. The initial condition of the simulations was set-up to emulate the actual environment around steam pipes. The data gathered were able to provide enough theoretical evidence showing that applying exothermic reaction causes a tremendous increase in the temperature of the steam.</p> Marvin Credo, Danilo Metra, Jr. Copyright (c) https://journal.evsu.edu.ph/index.php/itmj/article/view/38 Mon, 01 Jan 2018 00:00:00 +0800 NON-INVASIVE ELECTRICAL SYSTEM PARAMETERS MONITORING DEVICE FOR ENERGY AUDIT https://journal.evsu.edu.ph/index.php/itmj/article/view/39 <p>With the continuous rise in the cost of energy and environmental concerns such as global warming, it is imperative for developing countries in the Asia-Pacific region to adopt energy conservation measures given the limited resources. One of these measures is for an establishment to submit for an energy audit. Using experimental-developmental method, the study aims to develop a device that is non-invasive to monitor the values of the basic parameters of an electrical system for an energy audit. The device was evaluated in terms of its accuracy and functionality. It was found out that the average percentage errors for all the parameters tested were all in the allowable range. Moreover, t-test results revealed that there is no significant difference between the readings of the reference meters and the developed device. It is recommended that should other researchers modify the device, it should be made in a way that frequency will be added to the parameters that the device is capable of reading.</p> Marvin Credo Copyright (c) https://journal.evsu.edu.ph/index.php/itmj/article/view/39 Mon, 01 Jan 2018 00:00:00 +0800 ETHEPHON TREATMENT FOR EARLY SPROUTING OF YAM (Dioscorea alata L.) TUBERS var. VU-2 https://journal.evsu.edu.ph/index.php/itmj/article/view/40 <p>This study was conducted to determine the effect of ethephon on the sprouting behavior of <em>VU-2</em> 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.</p> Mary Ann Jully Regis, Marcelo Quevedo Copyright (c) https://journal.evsu.edu.ph/index.php/itmj/article/view/40 Mon, 01 Jan 2018 00:00:00 +0800 AUTOMATED WATER BILLING SYSTEM OF HINUNANGAN MUNICIPALITY https://journal.evsu.edu.ph/index.php/itmj/article/view/41 <p>A water billing system is an automated system that makes the complex task of billing easy, fast and accurate. This paper presents the development of an Automated Water Billing System for the local government unit of Hinunangan in the province of Southern Leyte, Philippines. The system constitutes two applications - Desktop and Mobile Reader.&nbsp; The System Development Life Cycle (SDLC) framework was adopted in the development process utilizing the Waterfall Model. Survey and interviews were also done as a supplementary technique of the fact-finding. The purposive sampling method was employed in the selection of respondents, and a researcher-made questionnaire was used in the systems evaluation. Weighted mean was used as a statistical treatment. Based on the results of the study, the developed system contributes a greater advantage in providing and delivering better operation, reporting, and services to the clientele.</p> Madelyn Manun-og, Mondani Manun-og, Norman Claridad, Rolly Tereso, Jeffrey Libarios Copyright (c) https://journal.evsu.edu.ph/index.php/itmj/article/view/41 Mon, 01 Jan 2018 00:00:00 +0800 A FACILE PREPARATION OF VO2-PVP NANOCOMPOSITE COATING FOR SMART WINDOW APPLICATION WITH IMPROVED VISIBLE TRANSMITTANCE https://journal.evsu.edu.ph/index.php/itmj/article/view/42 <p>Vanadium dioxide (VO<sub>2</sub>) is a promising smart window coating due to its thermochromic ability. However, its practical application is still on hold due to some limitations. For instance, a thin film coating of VO<sub>2</sub> suffers from low visible transmittance (<em>T<sub>vis</sub></em>). A new and simple technique to solve this restriction is by embedding nanoparticles onto film. Hence, this paper presents a preparation of nanocomposite coating derived from hydrothermally synthesized VO<sub>2 </sub>with improved <em>T<sub>vis</sub></em>. Using polyvinylpyrrolidone (PVP) as host matrix, nanostructured VO<sub>2</sub> is dispersed onto a glass sample via a spin coating process. X-ray diffraction (XRD) scan showed the presence of monoclinic VO<sub>2</sub> in the film. Surface analysis of the sample was carried out using atomic force microscopy (AFM). Based on the results, the roughness of the scanned area (1.5x1.5 μm<sup>2</sup>) has a mean height (S<sub>a</sub>), and root mean square height (S<sub>q</sub>) of 3.94 nm and 2.73 nm, respectively. Finally, calculation of the optical properties of the sample was done with the aid of a UV-vis spectrophotometer. Accordingly, the prepared nanocomposite film has a <em>T<sub>vis</sub></em> of 79.81% which is significantly higher than a thin film sample (<em>T<sub>vis</sub></em> = 65%).</p> H.M. Barra, S.K.
