    A preliminary study on the extraction of alginic acid from three species of brown algae: Sargassum polycystum, Sargassum cristaefolium and Turbinaria sp. in Taklong Is.,Guimaras
    Adelantar, Geoffrey V. (Division of Biological Sciences, College of Arts and Sciences, University of the Philippines Visayas, 1996-04)
    Three species of brown algae were harvested in Taklong Is., Guimaras. These were Sargassum polycystum, Sargassum cristaefolium, and Turbinaria sp. These brown algae were subjected to physical and chemical treatment to extract and compare the amount of their alginic acid in the form of sodium alginate. Four seaweed collections for extraction were made between August to December, 1995. Values obtained during the first three extractions gave almost similar results. S. polycystum exhibited the highest percentage yield of sodium alginate with a mean of 22.84%. It was followed by S. cristaefolium at 22.21%. Turbinaria sp. gave the lowest yield with a mean of 14.12%. The last extraction somehow showed a decrease in the percentage yield of all three samples. S. polycystum yielded just 20.00%, S. cristaefolium at 19.00% and Turbinaria sp. at just. 10.10%. Several factors may have contributed to the differences in the amount of alginic acid of the three species of brown algae. Among these are the inherent capability of the different species of brown algae to produce alginates, the thickness and sturdiness of the samples, the viscosity of the extracts, and seasonal changes.

    Personal meanings, experiences, and coping strategies for poverty of women 4P's beneficiaries
    Acuesta, Princes B. (Division of Biological Sciences, College of Arts and Sciences, University of the Philippines Visayas, 2015-06)
    This is a phenomenological study which sought to describe the experiences of poverty of women Pantawid Pamilyang Pilipino Program (4Ps) beneficiaries, their personal understanding of poverty, how their membership in 4Ps has affected their experiences of poverty, and their strategies for coping with difficulties associated with poverty. The participants of this study were four women 4Ps beneficiaries residing in Bay-bay Sur, Miagao, Iloilo. An interview guide questionnaire was constructed to gather narratives of poverty experiences from the participants. The results showed that personal meanings of poverty and the experiences of poverty among the participants are generally similar. All of the participants reported that 4Ps lessened their poverty experience in a relative sense. They all believed that daily struggles of inadequacy of basic needs could be fought by hard work. Lastly, all the participants believed that education is the key to their economic mobility and better way of life.

    Prevalence of Ascaris lumbricoides, Trichuris trichiura, and Enterobius vermicularis in the hands of preschool children in day care centers in Miagao, Iloilo
    Abellon, Rupert L., III (Division of Biological Sciences, Bachelor of Science in Public Health, University of the Philippines Visayas, 2002-03)
    The hands of 199 preschool children in Day Care Centers of Miag-ao, Iloilo were swabbed and examined for the presence of parasitic ova, specifically soil-transmitted parasites. Prevalence rates of parasitic ova were determined and tested for significant differences with variables that include age, sex, parent’s educational level, and location of the day care center of the preschoolers. Ascaris had a prevalence rate of 24.12% (48), Enterobius with 1.51% (3) and Trichuris with 1.01% (2). Toxocara canis had a 6.03% prevalence (12) in the hands of preschoolers. Using the Chi-square test to test for differences, it was shown that there were no significant differences in the presence of parasitic ova in the hands among preschoolers with regards to age, sex, and parent’s educational level except for location of the day care center. There was a significant difference in the prevalence rate of parasitic ova in the hands of preschoolers in coastal areas and those in non-coastal areas. Preschoolers in the coastal areas had a higher prevalence rate (29.82%) compared to those in the non-coastal areas (16.47%). With a sample of 121 stools from the same group of preschoolers, the study showed that there was no direct association between the presence of Ascaris ova in the hands and their presence in stools.

    Economics of copra production in selected barangays of Buenavista, Guimaras
    Aranda, Odessa T. (Division of Social Sciences, College of Art and Sciences, University of the Philippines Visayas, 1996-11)
    This paper provides a background and baseline information on the prevailing profile of copra production and profitability with the use of thirty-five producers based in Buenavista, Guimaras. This study also gave an overview on the problems encountered by copra producers and provided recommendations for the improvement of the local copra industry. Costs and returns analysis showed that average costs in copra production was P9.14/kg. Of the average costs, average fixed costs, average variable costs, and opportunity costs accounted for .33%, 26.59%, and 73.08%, respectively. Average fixed costs was P.03/kg where a third (33.33%) can be attributed to depreciation costs (P.02/kg). As to the average variable costs of the respondents, P2.43/kg was incurred which was primarily attributed by cost of hired labor (P89.71). Opportunity costs/kg for all producers was P6.68. The major opportunity costs (81.44%) was the implicit cost of coconuts. Average revenue was P9.43/kg. As a whole, the respondents gained P6.97/kg financial profit. Meanwhile, gross profit was P7.00 for all respondents. Copra producers in Buenavista, Guimaras earned a positive P0.29/kg economic profit. Payback period of 4.56 years, 7.30% return on investment, and 11.93% return on variable costs were other measures used to deterimine profitability in copra production.

    KAPIT PISI: Sa mga Kababayang Aeta Pisi Poso ay Ihahandog na Tulong Para Iwas Soil transmitted helminth Infection
    Acma, Kathleen Ann L.; Adolfo, Estee Joy G.; Bautista, Ezekiel Therese S.; Calimot, Andro Dominic A.; Dinopol, Christine Alexis S.; Gasataya, Chraisse Ann G.; Ingles, John Wibelle B.; Legaspi, Marienne C.; Linas, Pearl Joy C.; Lunar, Lanilyn Marie F.; Moises, Rochelle Anne Q.; Yunque, Vanessa Aura T. (Division of Biloigical Sciences, College of Arts and Sciences, University of the Philippines Visayas, 2015-05)
    Soil Transmitted Helminth Infection is one of the most common parasitic infections in the world, and it is considered as a neglected tropical disease which affects poverty-stricken, indigent and marginalized sectors of the community (World Health Organization, 2012). STH is transmitted through the fecal-oral route transmitted by the three most common species of helminths: Ascaris lumbricoides, Trichuris trichiura, and hookworm. In a study conducted in Davao del Norte, Philippines, the cumulative prevalence in indigenous people (IP) school children was significantly higher than in non-IP children with rates at 39.0% and 29.9%, respectively. The Kapit Pisi project aims to decrease the prevalence of soil transmitted helminth (STH) infections among children ages 0-12 years old of Sitio Igtuba, an Aeta community in Brgy. Camangahan, Guimbal, Iloilo. A qualitative stool examination was conducted before project implementation and results show that 56% of the children were positive for A. lumbricoides infection, 72% were positive for T. trichura infection, and 40% are positive for hookworm infection. Fifteen out of the twenty five (60%) children had mixed infection. They were further quantified as light, moderate, and heavy infection. In order to address the problem, the Kapit Pisi project organized a reliable, independent core group for the implementation and monitoring of the project well represented by the members of the community. A series of health education were conducted to increase the knowledge, attitude, and practices among the children through different triggering tools adapted from the Philippine Approach to Total Sanitation. This includes lectures on environmental sanitation, importance of handwashing, and disease transmission. Hygiene kits and slippers were also distributed to the children. Pre and posttest were conducted and results show that the KAP increased by 35% and 36% for children and parents, respectively. A deep well was constructed to provide safe water supply through bayanihan system. The well is already being used for their daily needs except for drinking and food preparation. The pisi poso was not feasible as of the moment because of inadequate water level due to the summer season. Two toilets were installed and ten are currently constructed which was spearheaded by Guimbal through the participation of different sectors of the community.
