Technological skills in the digital era of school librarians in Iloilo City: Basis for a proposed training design
Get PDFAbstract onlyThe descriptive study aims to determine the level of technological skills in the digital era of school librarians in Iloilo City as basis for a proposed training design. The respondents of the study were the school librarians in Iloilo City. This study both employed descriptive and inferential statistics to measure the variables under study. Frequency distribution, mean and rank were utilized as descriptive statistics. T-test and one-way analysis of variance (ANOVA) were also utilized as inferential statistics using the Statistical Package for the Social Science (SPSS) Software version 20. Results of the study found out that the school librarians in Iloilo demonstrate a “high” level of perceived technological skills with an average mean score of 4.04. However, there is a notable result found in the area of core applications of information tools and technologies which the school librarian responded a “moderate” result in demonstrating expertise in databases, metadata, information analysis and synthesis to improve retrieval and use in the organization. Additionally, in the area of core web tools, a “moderate” response was associated with the usage of web conferencing programs for synchronous, online meeting or learning and identifying and utilization of help menus, tutorials and support communities to acquire the necessary skills. The study inferred that it is a valid cognition of the rapid changing world of information, and the core web tools as product of emerging technologies and are seldom practiced or utilized by school librarians in the performance of their duties. Further, the results reveals that there were no significant differences noted on the level of technological skills when the respondents were classified according to age, educational attainment, length of experience, type of school library and number of ICT seminars/training attended for the last three years while sex and professional (librarian) eligibility status had a significant difference with their level of technological skills. This study concludes that school librarians in Iloilo City are skillful and technologically efficient.Includes bibliographical referencesMaster in Library and Information Scienc
Proposed "AA" slaughterhouse in Igbaras, Iloilo
Get PDFAbstract onlyMeat like pork, beef, or chicken has been the staple food of humans for the past years in order to survive and as the years passed by, the demand for meat production increases. An effective facility is needed to cater this demand of the consumer. Public slaughterhouse, also called as an abattoir, is a building used for killing farm animals where the meat is intended for human consumption. It is made to accommodate the number of meat products and the expanding volume of livestock community. Thus, to address this demand of the consumers the local government of the Municipality of Igbaras proposed to construct an “AA” slaughterhouse at Barangay Poblacion III, Igbaras, Iloilo where it will also serve as a producer for the meat production of the neighboring municipalities.
The proposed project is made of reinforced concrete. The National Meat Inspection Service, National Structural Code of the Philippines (NSCP) 2010 and Ultimate Strength Design (USD) were used as the basis for the structural analysis of reinforced concrete members and design. Anaerobic treatment will be used to treat the waste water from the slaughterhouse in order to minimize the foul odor. The proposed project will occupy a total area of 1 ,593 square meters with an estimated duration of 188 days and a total estimated cost of Php 12,982,776.44 that will come from the fund of local government of Igbaras and private sectors that are interested to donate and help in the construction of the project.Includes bibliographic referencesBachelor of Science in Civil Engineerin

Get PDFAbstract onlySlipper-cupped oyster shell contains 95% calcium carbonate and is considered as a promising source of lime in the future. This study aimed to design, fabricate, and evaluate a downdraft kiln to produce lime from Slipper-cupped oyster shells. Three kilograms of shells were calcined at 200 C for 30, 60, and 90 minutes, respectively, with 50 "C increment up to 500 °C which was the highest temperature the kiln had withstood. Calcined shells were powdered using LA Abrasion equipment for 150 seconds and the products obtained were characterized by particle size distribution using the Standard Tyler Sieve and calcium oxide content analysis conducted by the Regional Feed Laboratory. The results for particle size distribution showed that at temperature of 300 °C and residence time of 60 minutes, particle sizes smaller than 0.3 mm is 55.66 percent of the total mass which is greater compared to other trials. The results for percent calcium oxide (CaO) showed that the optimum operating temperature and residence time of the downdraft kiln in calcining Slipper-cupped oyster shell must be at a temperature of 400 °C and residence time of thirty (30) minutes to produce 54.726 % CaO can be considered already a very high-quality lime. Percent CaO of other trials is also greater than 50% and can also be categorized as high-quality lime.Includes bibliographical references (56-61)Bachelor of Science in Chemical Engineerin

Get PDFAbstract onlyThis study was designed for the purpose of evaluating acute dermal toxicity of Pomelo (Citrus maxima) peel essential oil extract which is known for its possible mosquito repellency in human and animals. This followed the limited availability of information regarding dermal toxicity of this citrus plant in Western Visayas (Region VI) despite the growing practice of utilizing the fruit peel essential oil as mosquito repellant. The fruit peel was subjected to steam distillation extraction process using aqueous solvent. All test animals were obtained from a New Zealand white rabbit breeder. Thus, acute dermal toxicity tests were conducted in healthy rabbits using the Institutional Animal Care and Use Committee (IACUC) guidelines. Irritation indices a 00 result, thus according to Draize these are considered as no occurrence of erythema and edema since none of them could reach PII of 5. On the other hand, findings from acute dermal toxicity tests showed no any overt signs of toxicity after 72 hours of treatment. Findings from this study have shown that, extracts from the peel of C. maxima exhibit acute dermal toxicity effects. The findings therefore suggests that essential oil extracts from the peel of C. maxima under its use as mosquito repellant applied on skin of rabbits do not cause any adverse effects externally.Includes bibliographical referencesBachelor of Science in Pharmac

Get PDFAbstract onlyThis study was conducted from January 30 to February 6, 2020 at the Western Visayas Integrated Agricultural Research Center (WESVIARC), Jaro, Iloilo City. This study aimed to determine the mycelial growth of Philippine edible straw mushroom (Volvariella volvacea) grown in banana leaf culture medium added with different levels of table sugar. The treatments consisted of different levels of table sugar such as: zero (control), 5, 10, 15, and 20 g/ per half liter of culture medium. The experimental treatments were laid out in a completely randomized design with three replications. Results of the study revealed that the first appearance of mycelia was observed from day 1 until day 2.7. The data showed that the mean no. of days to first mycelial appearance very slightly varied between 1.2 to 2.1 days (P>0.05). The highest spawning percentage (89%) was observed from the control culture medium and the one with 5 g of table sugar and lowest contamination percentage of 11%. The medium added with 10 g had 67% spawning percentage and 33% contamination. Moreover, the culture medium with 15 g and 20 g of table sugar had the lowest spawning and highest contamination percentage of 55.3% and 45%, respectively. Observed differences on both treatment means are not significantly different (P>0.05). Furthermore, the spawn-run diameter of Philippine edible straw mushroom (Volvariella volvacea) six days after inoculation revealed that spawn grown in control culture medium had the widest diameter of 5.93 cm, followed by 5 g of table sugar at 5.73 cm. Culture medium with 10 g and 15 g of table sugar had a spawn-run diameter of 4.90 cm and 4.83 cm, respectively. The narrowest spawn-run was obtained from culture medium with 20 g of table sugar at 4.20 cm. Just like other data calculated, statistical analysis revealed no significant difference (P>0.05) among treatment means.Includes bibliographical referencesBachelor of Science in Agricultur
Power demand medium term forecasting for Vitarich Corporation using data mining algorithm
Get PDFAbstract onlyForecasting provides a well founded decision in making future developments, in maintaining a stable system, and in avoiding technical risks. This study focuses on data mining the historical records of Vitarich Corporation, a feed milling company, accumulated starting April 2013 until September 2019. Applying Multiple Linear Regression, this aims to project power demand in the next five years which will be the basis in understanding the power system. Using Minitab Statistical Software, data were processed and analyzed, then the results were accumulated and compared to the data analysis gathered from another built-in application namely IBM Statistical Package for the Social Sciences (SPSS) in order to verify and secure its output forecast supervised by a professional statistician. It was determined during the first trial that only production was significant having the p-value equal to 0.0 while temperature, pressure, and humidity having p-values 0.505, 0.092, 0.864 respectively were out of range within the standard limit (0.0 - 0.05). Afterwhich, two succeeding reevaluations were done until it was observed that the residual result has a balanced standard deviation within the range (+4 to -4). Linear equation best fitted the model and gave the energy equation equal to 61822 + 1.1742 (PRODUCTION). The energy values were converted to its equivalent power values which is more vital in understanding capacity limit and power demand of Vitarich Corporation. Finally, it was determined that the system is still capable to withstand the requirement on the next five years having a forecasted power demand equal to 354.98 kW (443.72 kVA).Includes bibliographical referencesBachelor of Science in Electrical Engineerin
