Item Sagip COUGHamilya: Improving prevention, and case management & care seeking in Sitio Durog, Barangay Palaca, MiagaoAsorio, Leslie S.; Clarito, Thea Joy A.; Dolorosa, Rex Victor V.; Marecap, Mitzi N.; Napulan, Andrea Marie N.; Recabar, James Mathew V.; Rodriguez, Sael D.; Velasco, Princess Monic Q. (Division of Biological Sciences, College of Arts and Sciences, University of the Philippines Visayas, 2019-06)According to the 2018 Morbidity Diseases Reports of Miag-ao’s Rural Health Unit (RHU), Acute Respiratory Infection (ARI) is the main cause of morbidity among the children in the municipality. Upon further review, the community that was found to have the greatest number of ARI cases is that of Barangay Palaca. To contribute with the reduction of ARI cases in the said community, Project Sagip COUGHamilya was implemented in Sitio Durog. This project aims to reduce the number of current ARI cases among children aging 2 months to 11 years old by at least 50% after the 6-week project implementation. In order to accomplish such goal, the team utilized strategic components such as: (1) establishment of a core group called FamiLEADERS, (2) honing the ARI case management knowledge and skills of the barangay health workers (BHWs) through FamiLINANG sessions for BHWs, (3) improving the mothers’ & guardians’ knowledge, attitude, and practices (KAP) towards care seeking and case management for ARI through FamiLINANG sessions for mothers, and (4) raising the children’s awareness on cough etiquette, proper handwashing, and other key health practices through LINIStorya sessions. Upon implementation, the project’s outputs include the 80% increase in the ARI case management knowledge and skills of BHWs, 44.47% increase in the KAP of the mothers & guardians towards care seeking and case management for ARI, and 12.5% increase in the children’s awareness towards cough etiquette, proper handwashing, and other key health practices. All these results were statistically found to be significant improvements. In conclusion, the strategies done by the group significantly improved the care seeking, case management, and key health practices for ARI in Sitio Durog, Barangay Palaca. As a result, Projesct Sagip COUGHamilya contributed to the reduction of ARI cases by 80%, far exceeding the goal of the project and deeming it to be very effective and successful.Item Mud crab (Scylla serrata) shells for the removal of humic acids from Santa Barbara well waterAsdillo, Reina Jean A. (Department of Chemistry, College of Arts and Sciences, University of the Philippines Visayas, 2010-04)The chemical contamination of drinking water from a wide range of contaminants such as humic acids can potentially lead to health-related in living organisms, especially humans. In rural areas of the Philippines, the use of low cost methods to remove water pollutants is, therefore, of great interest. In this study, osterized mud crab (Scylla serrata) shells or exoskeletons from cooked crab wastes were used to remove humic acids from the Santa Barbara well water. Adsorption experiments were done to evaluate its capacity to remove humic acids from the well water. Adsorption Isotherms and Fourier Transform Infrared Spectroscopy were employed to study the characteristics of the adsorption of humic acids onto the OSSE (osterized Scylla serrata exoskeletons). Adsorption experiments showed that at an average 1.0010 g of OSSE and after six hours of agitation, an average 74.95% of humic substances were removed from 50 mL of Montinola, Santa Barbara well water sample. Isotherm experiments showed that the experimental data can be fitted in both Langmuir and Freundlich models with low K values of 0.0235 L/mg and 0.4450 (mg/g)(L/mg), respectively. Based on the results of the above experiments, OSSE is a good adsorbent for humic acids in well waters (although more research need to be done on the removal of the substances remaining in the water after OSSE treatment) and the U-OSSE (used osterized Scylla serrata exoskeletons) can possibly be recycled.Item The growth and yield performance of oyster mushroom (Pleurotus ostreatus Fries) using fish wastewater as fertilizerArroyo, Karen T. (Division of Biological Sciences, College of Arts and Sciences, University of the Philippines Visayas, 2000-04)Oyster mushroom, Pleurotus ostreatus, is an edible wood-inhabiting fungi that continues to gain popularity in the Philippines, as well as in other tropical countries. With the use of modern technology, this mushroom can be grown in the Philippines, provided sufficient moisture is present. Its present cultivation is limited, perhaps due to insufficiency of planting materials and the limited knowledge about its culture. The main objective of the study was to establish the possibility of the replacement of urea, the commonly used fertilizer for mushroom cultivation by fish wastewater. The study also aimed to compare the effects of different concentrations of fish wastewater on the growth of mushrooms and determine which treatment produced the best results. A total of five groups were used: two control groups (positive and negative - using urea and water, respectively) and three experimental groups, the latter with different concentrations of fish wastewater serving as alternative fertilizer (A: 10%, B: 20%, C: 30%). Fruiting bags were inoculated with oyster mushroom spawn, and after a month of incubation, the growing mushrooms were assessed using the parameters of number, weight, length, and diameter. Results showed that the weight of oyster mushrooms was heaviest when the substrate was sprayed with plain water. However, the number of mushrooms harvested, their length, and the width of the pilei were not affected by spraying the substrate with urea or moistening these with up to 30% fish wastewater. The conclusions reached were: 1) when using sawdust as substrate for oyster mushroom cultivation, it is best to simply use water to maintain the moisture of the material; 2) sawdust used in combination with low concentration of fish wastewater (10%) can result in good production; 3) neither nitrogen nor urea may be a critical factor for the growth of oyster mushroom on sawdust; and 4) high amount of phosphorus and low potassium content of fish wastewater are favorable for oyster mushroom growth.Item Project EDI WAM!: Everybody Do It: War Against Malnutrition in Brgy. Roma, San Joaquin, IloiloBalogo, Philip G.; Bomediano, Maria Jonnah R.; Esparagoza, Marevi T.; Gallo, Czareena Anne; Mallari , Maria Katerina; Murillo, Gilbert Guy D.; Ortono, Jevi Marie P.; Oteda, Kristine Joy D.; Pameroyan, Nesly Joy G.; Radones, Charmaine Mae Keyien G.; Santocildes, Camille S.; Tirador, Anna Katharina L. (Division of Biological Sciences, College of Arts and Sciences, University of the Philippines Visayas, 2015-05)The Millenium Development Goals for the Philippines by 2015 is to reduce the underweight-by-age prevalence to 17.2% among 0-5 years old children. So far in 2013, the prevalence decreased from 20.7% in 2003 to 19.9%. Western Visayas ranks second (26.0%) in the most malnourished regions in the country, with trends increasing in Iloilo from 25.1% in 2008 to 27.4% in 2013. According to the National Nutrition Council, this small change in number for the past 10 years makes it unlikely that the country will achieve its MDG. Project EDI WAM! Every body Do It: War Against Malnutrition in Barangay Roma, San Joaquin, Iloilo aims to decrease the prevalence of malnutrition by 70% among children aged 24 to 72 months. Operation Timbang showed that out of the 42 children, 11 were identified as malnourished, giving a prevalence of 26.19%. Project EDI WAM! aims to decrease the number of undernourished children through health education, feeding, and supplementation programs. A functional core group of 9 members was formed and was later transformed into a Barangay Health Board. Cooking lessons dubbed Pinoy Mother Chef improved the mothers' food preparation practices and behavior. Hygiene and Sanitation increased by 36.60%, while proper meal planning increased by 24.83%. Ready-to-Use therapeutic food (RUTF) was prepared and supplemented to the children. Knowledge of mothers on health and nutrition also increased by 35.54%. Out of the 11 malnourished children, 4 were turned to normal, giving a decrease of 36.36%. The 70% goals was not achieved and may be attributed to the short period of time that the project was implemented. However there is a significant increase in weight among all the recipients (2.79% ) and malnourished (4.92%). A Mothers’ Association was established to continue the project advocacy, making the cooking and feeding program an annual event.Item Preparation and characterization of chitin-humic acid hybrid and chitin-humic acid hybrid hydrogel as absorbent for Cu(II)Balgos, Blyth Angela C. (Department of Chemistry, College of Arts and Sciences, University of the Philippines Visayas, 2017-06)Gelatinous chitin was functionalized with humic acid to produce a chitinhumic acid hybrid. The gelatinous chitin was protonated using HC1 and humic acid was deprotonated by using NaOH in separate containers. The protonated gelatinous chitin and the deprotonated humic acid were then mixed to form Hie chitin-humic acid hybrid. A portion of the chitin-humic acid hybrid was used to prepare the chitin-humic acid hydrogel. The chitin-humic acid hybrid hydrogel was then prepared using 1,2,3,4- butanetetracarboxylic dianhydride(BTCA) as crosslinker. The chitin-humic acid hybrid hydrogel was then characterized using FT-IR and swelling test. The degree of swelling of the chitin-humic acid hydrogel was found to be 38.10 ± 3.06. It can also be inferred from the results of the swelling test that the chitin-humic acid hybrid hydrogel has a low crosslink density. Characterization by FT-IR suggested successful immobilization for the hybrid and BTCA crosslinking for the hydrogel. The potential of chitin-humic acid hybrid and chitin-humic acid hybrid hydrogel to adsorb Cu(II) in a solution was then evaluated. The process was done by subjecting the chitin-humic acid hybrid to Cu(II) adsorption. The results for Cu(II) adsorption test was subjected to a Shapiro- Wilk test for normality and was determined to have normally distributed data. One- sample T-test was then used to compare the adsorption capacity of the hybrid and hydrogel. The mean % Cu(II) Removal of the chitin-humic acid hybrid and chitinhumic acid hybrid hydrogel were 41.36 ± 2.35% and 51.21 ± 1.32%, respectively. Results suggested that the chitin-humic acid hybrid hydrogel has significantly higher % Cu(II) Removal compared to the chitin-humic acid hybridItem Spatial variations of Benthic meiofauna communities from Palompon Bay, Northern LeyteBalasa, Melvy June (Division of Biological Sciences, College of Arts and Sciences, University of the Philippines Visayas, 2013-04)Meiofauna play a significant role in maintaining ecological balance in marine ecosystems especially in the dynamics of the seagrass meadows. The meiofauna links the upper trophic level with detritus-feeding organisms. Only few studies have been conducted in the Philippines, while no studies have been. This study was conducted in Palompon, northern Leyte in November 2011, to determine the spatial distribution of meiobenthic fauna in the area and to compare community structure in terms of species composition, species density, and species diversity among five stations included in the survey. Twenty taxa were identified with nematodes being numerically dominant, followed by harpacticoid copepods. It also showed the highest mean abundance for the entire habitat type. The overall mean density was 194585.1528 ind. m2, with the highest population at station 4. And the lowest population was recorded at station 2. Soft bottom habitat showed the highest recorded mean density among the 5 stations, Harpacticoids mostly dominated sandy substrate while nematodes were widely distributed.Item As the rivers flows: A history of laws and politics affecting the Iloilo River from the 1970's to the presentBaliao, Martin Earl D. (Division of Social Sciences, College of Arts and Sciences, University of the Philippines Visayas, 2013-04)This paper attempts to examine the history of national and local river laws and policies that pertain to changes in the ecology of the Iloilo River since the 1970s. Furthermore, this paper seeks to investigate the reasons for the laws and policies and the actions taken by different administrations across the decades that affected the ecology of the river. Library research and one interview was used to gather the necessary data for this research paper. This paper will conclude by discussing the effects of the different laws, policies, and plans on the ecology of the Iloilo River.Item Treatment of Vibrio harveyi-infected Penaeus monodon using Alibutbut (Tabernaemontana pandacaqui Poir.) plant powderBacaling, Marivic T. (Division of Physical Sciences and Mathematics, College of Arts and Sciences, University of the Philippines Visayas, 2005-04)The cytotoxicity test of crude methanolic leaf extract using Brine Shrimp Lethality Assay revealed that Alibutbut (Tabernaemontana pandacaqui Poir.) is safe to use in treating vibrio-infected penaeid shrimps. The effectiveness of the alibutbut powder against vibriosis was examined through the determination of the post-larvae 20 (PL 20) penaeid shrimp mortality and the water microbial assay after 48 hours. Percent penaied shrimp mortality (0-6.67%) and microbial count (2.91 x 10^4- 3.26 x 104 cfu/mL) of the plant treatments were significantly lower compared to the negative control (no treatment) that exhibited 50% penaeid shrimp mortality and a microbial count greater than 6.00 x 10^4 cfu/mL. The results of the experiment showed that Alibutbut plant powder is indeed effective in controlling Vibrio harveyi bacteria.Item Survey of pathogenic bacteria in bottom sediments of Iloilo River: An assessment of water sanitary qualityAraneta, Karla Teresa S.; Bugayong, Adrienne Marrie S.; Cabanilla, Jennifer C.; Caro, Mary Ann Gina C.; Gayatgay, Christian Era U.; Nufuar, Ernest Jan T.; Rufino Krystal Hope S. (Division of Biological Sciences, College of Arts and Sciences, University of the Philippines Visayas, 2009-03)This study assessed the water sanitary quality of the Iloilo River by determining the monthly heterotophic plate count (HPC), total coliform (TC), fecal coliform (FC), and fecal streptococcus (FS) counts of the bottom sediments in five sampling sites from October 2008 to February 2009. These parameters were then correlated with the physico-chemical parameters that were additionally obtained from the river water. The presence of Salmonella spp, E. coli. Vibrio spp, and fecal Streptococcus were also determined as indicators of the pathogenic bacteria in the bottom sediments of the Iloilo River. Using the FC:FS ratio, the study further distinguished fecal contamination sources from each site as human, animal, or mixed in origin. An assessment of sediment quality was done using DENR standards for TC and Kohl and Albinger's sediment quality criteria for HPC and FC. Sediment samples were taken from the following sampling sites along the Iloilo River: 1) Forbes. 2) Dungon, 3) IBRD, 4) Carpenter's, and 5) So-oc. No significant difference in any of the physico-chemical or microbiological parameters were found among sampling stations. However, analysis and comparison of the microbiological parameters of bottom sediments in terms of months showed significant temporal variability HPC, TC, and FC alternately decrease and increase every month while FS showed a generally increasing trend. The following correlations between the microbiological and physico-chemical parameters were found. 1) temperature with HPC and FS , 2) salinity with FS count, and 3) dissolved oxygen concentration with TC and FC Counts. The mean percentage of bottom sediment samples with Salmonella ranged from 3% to 10% while more than half of samples from all sampling sites showed the presence of Vibrio spp. and S. faecalis. Samples with E.coli from all sites ranged from 3 to 14%. Fecal contamination sources varied across sampling sites. So-oc show ed mostly animal sources as its orgin of fecal contamination, while other sites had either animal, human or mixed sources. S. faecalis and E. coli exhibited multiple antibiotic resistance, a grow ing health concent in many of today's rivers. All isolates were susceptible to Gentamicin and Ciprofloxacin but resistant to Penicillin. Based on HPC and FC values the degree of loading with easily decomposable organic substance and feces among the sampling sites ranges from very little to little. TC count of the sediment samples from all the sites does not exceed the limit of 5000 CFU/ 100ml set by the DENR. Results suggest that sediments were not a significant reservoir of bacterial pollution at the time this study was conducted.Item Knowledge, attitudes, and practices on dengue vectors of households in Tumagboc Catchment Area, Miagao, IloiloArbizo, Jeric L.; Baldevarona, Rosa Lea S.; Caoyonan, Louise Asuncion D.; Gabasa, Marah Febcy J.; Mapa, Fernie Love D.; Patria, Elaine Joy M.; Tenchavez, Darlene Ruth B.; Trivilegio, Enna Fleur C. (Division of Biological Sciences, College of Arts and Sciences, University of the Philippines Visayas, 2011-03)Previous studies have shown that knowledge, attitudes and practices have an association with the dengue vector control. As such, the independence of mosquito population on the sociodemographic characteristics and KAP of the household heads in Tumagboc Catchment Area, Miagao, Iloilo was tested. Based on the results, the household heads generally are unemployed, married females aging 41 to 50. Their households are composed of 4 to 7 members with no or one child below 15 years, and usually receive below P 1999 per month. Most of them are informed about dengue fever, but only one had suffered from it in the last two years. Moreover, they have moderate knowledge, poor attitudes, but good practices regarding dengue prevention. The container index is 2.71 for crude mosquito larvae and pupae population, and 0.39 for Aedes sp. The house index is 9.72, while the Breteaux indexis 13.19. Chi-square analysis at 0.05 level of significance confirmed the independence of mosquito larvae and pupae population from monthly income, dengue information reception, knowledge, attitudes and practices. A solid reason was the untimely conduct of the study in the beginning of the summer season, when stagnant water has dried up and with few vulnerable breeding sites.
